Administrator means the Administrator of the Environmental
Protection Agency or the Administrator's authorized representative.
Agency means the Environmental Protection Agency.
Applicant means a person or entity who submits an application for a
reference or equivalent method determination under Sec. 53.4, or a
person or entity who assumes the rights and obligations of an applicant
under Sec. 53.7. Applicant may include a manufacturer, distributor,
supplier, or vendor.
Automated method or analyzer means a method for measuring
concentrations of an ambient air pollutant in which sample collection
(if necessary), analysis, and measurement are performed automatically by
an instrument.
Candidate method means a method for measuring the concentration of
an air pollutant in the ambient air for which an application for a
reference method determination or an equivalent method determination is
submitted in accordance with Sec. 53.4, or a method tested at the
initiative of the Administrator in accordance with Sec. 53.7.
Class I equivalent method means an equivalent method for
PM2.5 which is based on a sampler that is very similar to the
sampler specified for reference methods in appendix L of this part, with
only minor deviations or modifications, as determined by EPA.
Class II equivalent method means an equivalent method for
PM2.5 that utilizes a PM2.5 sampler in which an
integrated PM2.5 sample is obtained from the atmosphere by
filtration and is subjected to a subsequent filter conditioning process
followed by a gravimetric mass determination, but which is not a Class I
equivalent method because of substantial deviations from the design
specifications of the sampler specified for reference methods in
appendix L of part 50 of this chapter, as determined by EPA.
Class III equivalent method means an equivalent method for
PM2.5 that has been determined by EPA not to be a Class I or
Class II equivalent method. This fourth type of PM2.5 method
includes alternative equivalent method samplers and continuous
analyzers, based on designs and measurement principles different from
those specified for reference methods (e.g., a means for estimating
aerosol mass concentration other than by conventional integrated
filtration followed by equilibration and gravimetric analysis. These
samplers (or monitors) are those deemed to be substantially different
from reference method samplers and
[[Page 7]]
are likely to use components and methods other than those specified for
reference method samplers.
Collocated describes two or more air samplers, analyzers, or other
instruments which sampler the ambient air that are operated
silmultaneously while located side by side, separated by a distance that
is large enough to preclude the air sampled by any of the devices from
being affected by any of the other devices, but small enough so that all
devices obtain identical or uniform ambient air samples that are equally
representative of the general area in which the group of devices is
located.
Equivalent method means a method for measuring the concentration of
an air pollutant in the ambient air that has been designated as an
equivalent method in accordance with this part; it does not include a
method for which an equivalent method designation has been canceled in

equivalent method samplers and monitors.
ISO-certified auditor means an auditor who is either certified by
the Registrar Accreditation Board (in the United States) as being
qualified to audit quality systems using the requirements of recognized
standards such as ISO 9001, or who, based on information submitted to
the EPA, meets the same general requirements as provided for ISO-
certified auditors.
Manual method means a method for measuring concentrations of an
ambient air pollutant in which sample collection, analysis, or
measurement, or some combination therof, is performed manually. A method
for PM10 or PM2.5 which utilizes a sampler that
requires manual preparation, loading, and weighing of filter samples is
considered a manual method even though the sampler may be capable of
automatically collecting a series of sequential samples.
PM2.5 sampler means a device, associated with a manual
method for measuring PM2.5, designed to collect
PM2.5 from an ambient air sample, but lacking the ability to
automatically analyze or measure the collected sample to determine the
mass concentrations of PM2.5 in the sampled air.
PM10 sampler means a device, associated with a manual
method for measuring PM10, designed to collect
PM10 from an ambient air sample, but lacking the ability to
automatically analyze or measure the collected sample to determine the
mass concentrations of PM10 in the sampled air.
Reference method means a method of sampling and analyzing the
ambient air for an air pollutant that is specified as a reference method
in an appendix to part 50 of this chapter, or a method that has been
designated as a reference method in accordance with this part; it does
not include a method for which a reference method designation has been
canceled in accordance with Sec. 53.11 or Sec. 53.16.
Sequential samples for PM samplers means two or more PM samples for
sequential (but not necessarily contiguous) time periods that are
collected automatically by the same sampler without the need for
intervening operator service.
Test analyzer means an analyzer subjected to testing as part of a
candidate method in accordance with subparts B, C, D, E, or F of this
part, as applicable. Test sampler means a PM10 sampler or a
PM2.5 sampler subjected to testing as part of a candidate
method in accordance with subparts C, D, E, or F of this part.

(B) Where the appendix specifies a measurement principle and
calibration procedure, to cancel reference method designations based on
the appendix.
[[Page 18]]
(C) To cancel equivalent method designations based on the existing
reference method(s).
(ii) The notice of proposed rulemaking will include the terms or
substance of the proposed revision, will indicate what period(s) of time
the Administrator proposes to allow for replacement of existing methods
under section 2.3 of appendix C to part 58 of this chapter, and will
solicit public comments on the proposal with particular reference to the
considerations set forth in paragraphs (a) and (b) of this section.
(2)(i) If, after consideration of comments received, the
Administrator determines that the appendix to part 50 in question should
be revised, the Administrator will, by publication in the Federal
Register:
(A) Promulgate the proposed revision, with such modifications as may
be appropriate in view of comments received.
(B) Where the appendix to part 50 (prior to revision) specifies a
measurement principle and calibration procedure, cancel reference method
designations based on the appendix.
(C) Cancel equivalent method designations based on the existing
reference method(s).

under Sec. 53.8(c). The requirements and procedures for cancellation set
forth in Sec. 53.11 shall be inapplicable to cancellation of reference
or equivalent method designations under this section.
(4) If the appendix to part 50 of this chapter in question is
revised to specify a new measurement principle and calibration procedure
on which the applicant's candidate method is based, the Administrator
will take appropriate action under Sec. 53.5 to determine whether the
candidate method is a reference method.
(5) Upon taking action under paragraph (e)(2) of this section, the
Administrator will send notice of the action to all applicants for whose
methods reference and equivalent method designations are canceled by
such action.
(f) An applicant who has received notice of a determination under
paragraph (d)(2) of this section may appeal the determination by taking
one or more of the following actions:
(1) The applicant may submit new or additional information in

Subpart B--Procedures for Testing Performance Characteristics of
Automated Methods SO2, CO, O3, and NO2
Sec. 53.20 General provisions.
(a) The test procedures given in this subpart shall be used to test
the performance of candidate automated methods against the performance
specifications given in table B-1. A test analyzer representative of the
candidate automated method must exhibit performance better than, or
equal to, the specified value for each such specification (except Range)
to satisfy the requirements of this subpart. Except as provided in
paragraph (b) of this section, the range of the candidate method must be
the range specified in table B-1 to satisfy the requirements of this
subpart.
(b) For a candidate method having more than one selectable range,
one range must be that specified in table B-1 and a test analyzer
representative of the method must pass the tests required by this
subpart while operated in that range. The tests may be repeated for a
broader range (i.e., one extending to higher concentrations) than that
specified in table B-1 provided that the range does not extend to
concentrations more than two times the upper range limit specified in
table B-1. If the application is for a reference method determination,
the tests may be repeated for a narrower range (one extending to lower
concentrations) than that specified in table B-1.
If the tests are conducted or passed only for the specified range, any
reference or equivalent method determination with respect to the method
will be limited to that range. If the tests are passed for both the
specified range and a broader range (or ranges), any such determination
will include the broader range(s) as well as the specified range,
provided that the tests required by subpart C of this part (if
applicable) are met for the broader range(s). If the tests are passed
for both the specified range and a narrower range, a reference method
determination for the method will include the narrower range as well as
the specified range. Appropriate test data shall be submitted for each
range sought to be included in a reference or equivalent
[[Page 20]]
method determination under this paragraph (b).
(c) For each performance specification (except Range), the test
procedure shall be initially repeated seven (7) times to yield 7 test
results. Each result shall be compared with the corresponding
specification in table B-1; a value higher than or outside that
specified constitutes a failure. These 7 results for each parameter
shall be interpreted as follows:
(1) Zero (0) failures: Candidate method passes the performance
parameter.
(2) Three (3) or more failures: Candidate method fails the
performance parameter.
(3) One (1) or two (2) failures: Repeat the test procedures for the
parameter eight (8) additional times yielding a total of fifteen (15)
test results. The combined total of 15 test results shall then be
interpreted as follows:
(i) One (1) or two (2) failures: Candidate method passes the
performance parameter.
(ii) Three (3) or more failures: Candidate method fails the
performance parameter.

time, and precision shall be combined into a single sequential procedure
to be conducted at various line voltages and ambient temperatures
specified in Sec. 53.23(e). The tests for noise, lower detectable limit,
and interference equivalents shall be made at any temperature between 20
deg.C. and 30 deg.C. and at any normal line voltage between 105 and
125 volts, and shall be conducted such that not more than three (3) test
results for each parameter are obtained per 24 hours.
(e) All response readings to be recorded shall first be converted to
concentration units according to the calibration curve constructed in
accordance with Sec. 53.21(b).
(f) All recorder chart tracings, records, test data and other
documentation obtained from or pertinent to these tests shall be
identified, dated, signed by the analyst performing the test, and
submitted.

(a) Set-up and start-up of the test analyzer shall be in strict
accordance with the operating instructions specified in the manual
referred to in Sec. 53.4(b)(3). Allow adequate warm-up or stabilization
time as indicated in the operating instructions before beginning the
tests. If the candidate method does not include an integral strip chart
recorder,
[[Page 21]]
connect the output signal of the test analyzer to a suitable strip chart
recorder of the servo, null-balance type. This recorder shall have a
chart width of at least 25 centimeters, chart speeds up to 10 cm per
hour, a response time of 1 second or less, a deadband of not more than
0.25 percent of full scale, and capability either of reading
measurements at least 5 percent below zero or of offsetting the zero by
at least 5 percent.
Note: Other data acquisition components may be used along with the
chart recorder during conduct of these tests. Use of the chart recorder
is intended only to facilitate evaluation of data submitted.
(b) Calibration of the test analyzer shall be as indicated in the
manual referred to in Sec. 53.4(b)(3) and as follows: If the chart
recorder does not have below zero capability, adjust either the controls
of the test analyzer or the chart recorder to obtain a +5% offset zero
reading on the recorder chart to facilitate observing negative response
or drift. If the candidate method is not capable of negative response,
the test analyzer (not recorder) shall be operated with an offset zero.
Construct and submit a calibration curve showing a plot of recorder
scale readings (ordinate) against pollutant concentrations (abscissa). A
plot of output units (volts, millivolts, milliamps, etc.) against
pollutant concentrations shall also be shown for methods not including
an integral chart recorder. All such plots shall consist of at least
seven (7) approximately equally spaced, identifiable points, including 0
and 905 percent of full scale.
(c) Once the test analyzer has been set up and calibrated and the
tests started, manual adjustment or normal periodic maintenance is
permitted only every 3 days. Automatic adjustments which the test
analyzer performs by itself are permitted at any time. The submitted
records shall show clearly when any manual adjustment or periodic
maintenance was made and describe the operations performed.
(d) If the test analyzer should malfunction during any of the
performance tests, the tests for that parameter shall be repeated. A
detailed explanation of the malfunction, remedial action taken, and
whether recalibration was necessary (along with all pertinent records
and charts) shall be submitted. If more than one malfunction occurs, all
performance test procedures for all parameters shall be repeated.
(e) Tests for all performance parameters shall be completed on the
same test analyzer, except that use of multiple test analyzers to
accelerate testing will be permitted when alternate ranges of a multi-
range candidate method are being tested.
Sec. 53.22 Generation of test atmospheres.
(a) Table B-2 specifies preferred methods for generating test
atmospheres and suggested methods of verifying the concentrations. Only
one means of establishing the concentration of a test atmosphere is
normally required. If the method of generation can produce reproducible
concentrations, verification is optional. If the method of generation is
not reproducible, then establishment of the concentration by some
verification method is required. However, when a method of generation
other than that given in table B-2 is used, the test concentration shall
be verified.
(b) The test atmosphere delivery system shall be designed and
constructed so as not to significantly alter the test atmosphere
composition or concentration during the period of the test. The delivery
system shall be fabricated from borosilicate glass or FEP Teflon.
(c) The output of the test atmosphere generation system shall be
sufficiently stable to obtain stable response during the required tests.
If a permeation device is used for generation of a test atmosphere, the
device, as well as the air passing over it, shall be controlled to
0.1 deg.C.
(d) All diluent air shall be zero air free of contaminants likely to
cause a detectable response on the test analyzer.

Sec. 53.23 Test procedures.
(a) Range--(1) Technical definition. Nominal minimum and maximum
concentrations which a method is capable of measuring.
Note: The nominal range is specified at the lower and upper range
limits in concentration units, for example, 0-0.5 p/m.
(2) Test procedure. Submit a suitable calibration curve, as
specified in Sec. 53.21(b), showing the test analyzer's response over at
least 95 percent of the required range.
Note: A single calibration curve will normally suffice.
(b) Noise--(1) Technical definition. Spontaneous, short duration
deviations in output, about the mean output, which are not caused by
input concentration changes. Noise is determined as the standard
deviation about the mean and is expressed in concentration units.
(2) Test procedure. (i) Allow sufficient time for the test analyzer
to warm up and stabilize. Determine at two concentrations, first using
zero air and then a pollutant test gas concentration as indicated below.
The noise specification in table B-1 shall apply to both of these tests.
(ii) Connect an integrating-type digital meter (DM) suitable for the
test analyzer's output and accurate to three significant digits, to
measure the analyzer's output signal.
Note: Use of a chart recorder in addition to the DM is optional.
(iii) Measure zero air for 60 minutes. During this 60-minute
interval, record twenty-five (25) readings at 2-minute intervals. (See
Figure B-2 in appendix A.)
(iv) Convert each DM reading to concentration units (p/m) by
reference to the test analyzer's calibration curve as determined in
Sec. 53.21(b). Label the converted DM readings r1,
r2, r3 . . . ri . . . r25.
(v) Calculate the standard deviation, S, as follows:
where i indicates the i-th DM reading in ppm.
(vi) Let S at 0 ppm be identified as So; compare So
to the noise specification given in table B-1.
(vii) Repeat steps (iii) through (vi) of this section using a
pollutant test atmosphere concentration of 805 percent of
the upper range limit (URL) instead of zero gas, and let S at 80 percent
of the URL be identified as S80. Compare S80 to
the noise specification given in table B-1.
(viii) Both S0 and S80 must be less than or
equal to the specification for noise to pass the test for the noise
parameter.
(c) Lower detectable limit--(1) Technical definition. The minimum
pollutant concentration which produces a signal of twice the noise
level.
(2) Test procedure. (i) Allow sufficient time for the test analyzer
to warm up and stabilize. Measure zero air and record the stable reading
in ppm as BZ. (See Figure B-3 in appendix A.)
(ii) Generate and measure a pollutant test atmosphere concentration
equal to the value for the lower detectable limit specified in table B-
1.
Note: If necessary, the test atmosphere concentration may be
generated or verified at a higher concentration, then accurately diluted
with zero air to the final required concentration.
[[Page 24]]
(iii) Record the test analyzer's stable indicated reading, in ppm,
as BL.
(iv) Determine the Lower Detectable Limit (LDL) as LDL =
BL-BZ. Compare this LDL value with the noise
level, S0, determined in Sec. 53.23(b), for 0 concentration
test atmosphere. LDL must be equal to or higher than 2S0 to
pass this test.
(d) Interference equivalent--(1) Technical definition. Positive or
negative response caused by a substance other than the one being
measured.
(2) Test procedure. The test analyzer shall be tested for all
substances likely to cause a detectable response. The test analyzer
shall be challenged, in turn, with each interfering agent specified in
table B-3. In the event that there are substances likely to cause a
significant interference which have not been specified in table B-3,
these substances shall be tested at a concentration substantially higher
than that normally found in the ambient air. The interference may be
either positive or negative, depending on whether the test analyzer's
response is increased or decreased by the presence of the interferent.
Interference equivalents shall be determined by mixing each interferent,
one at a time, with the pollutant at the concentrations specified in
table B-3, and comparing the test analyzer's response to the response
caused by the pollutant alone. Known gas-phase reactions that might
occur between an interferent and the pollutant are designated by
footnote 3 in table B-3. In these cases, the interference equivalent
shall be determined in the absence of the pollutant.
(i) Allow sufficient time for warm-up and stabilization of the test
analyzer.
(ii) For a candidate method using a prefilter or scrubber based upon
a chemical reaction to derive part of its specificity, and which
requires periodic service or maintenance, the test analyzer shall be
``conditioned'' prior to each interference test as follows:

(A) Service or perform the indicated maintenance on the scrubber or
prefilter as directed in the manual referred to in Sec. 53.4(b)(3).
(B) Before testing for each interferent, allow the test analyzer to
sample through the scrubber a test atmosphere containing the interferent
at a concentration equal to the value specified in table B-3. Sampling
shall be at the normal flow rate and shall be continued for 6 continuous
hours prior to testing.
(iii) Generate three test atmosphere streams as follows:
(A) Test atmosphere P: Pollutant concentration.
(B) Test atmosphere I: Interference concentration.
(C) Test atmosphere Z: Zero air.
(iv) Adjust the individual flow rates and the pollutant or
interferent generators for the three test atmospheres as follows:
(A) The flow rates of test atmospheres I and Z shall be identical.
(B) The concentration of pollutant in test atmosphere P shall be
adjusted such that when P is mixed (diluted) with either test atmosphere
I or Z, the resulting concentration of pollutant shall be as specified
in table B-3.
(C) The concentration of interferent in test atmosphere I shall be
adjusted such that when I is mixed (diluted) with test atmosphere P, the
resulting concentration of interferent shall be equal to the value
specified in table B-3.
(D) To minimize concentration errors due to flow rate differences
between I and Z, it is recommended that, when possible, the flow rate of
P be from 10 to 20 times larger than the flow rates of I and Z.
(v) Mix test atmospheres P and Z by passing the total flow of both
atmospheres through a mixing flask.
(vi) Sample and measure the mixture of test atmospheres P and Z with
the test analyzer. Allow for a stable reading, and record the reading,
in concentration units, as R (see Figure B-3).
(vii) Mix test atmospheres P and I by passing the total flow of both
atmospheres through a mixing flask.
(viii) Sample and measure this mixture. Record the stable reading,
in concentration units, as RI.
(ix) Calculate the interference equivalent (IE) as:
IE = RI-R
IE must be equal to or less than the specification given in table B-1
for each interferent to pass the test.
(x) Follow steps (iii) through (ix) of this section, in turn, to
determine the interference equivalent for each interferent.
(xi) For those interferents which cannot be mixed with the
pollutant, as indicated by footnote (3) in table B-3, adjust the
concentration of test atmosphere I to the specified value without being
mixed or diluted by the pollutant test atmosphere. Determine IE as
follows:
(A) Sample and measure test atmosphere Z (zero air). Allow for a
stable reading and record the reading, in concentration units, as R.
(B) Sample and measure the interferent test atmosphere I. If the
test analyzer is not capable of negative readings, adjust the analyzer
(not the recorder) to give an offset zero. Record the stable reading in
concentration units as RI, extrapolating the calibration
curve, if necessary, to represent negative readings.
(C) Calculate IE=RI-R. IE must be equal to or less than
the specification in table B-1 to pass the test.
(xii) Sum the absolute value of all the individual interference
equivalents. This sum must be equal to or less than the total
interferent specification given in table B-1 to pass the test.
(e) Zero drift, span drift, lag time, rise time, fall time, and
precision--(1) Technical definitions--(i) Zero drift: The change in
response to zero pollutant concentration, over 12- and 24-hour periods
of continuous unadjusted operation.
(ii) Span drift: The percent change in response to an up-scale
pollutant concentration over a 24-hour period of continuous unadjusted
operation.
(iii) Lag time: The time interval between a step change in input
concentration and the first observable corresponding change in response.
(iv) Rise time: The time interval between initial response and 95
percent of final response after a step increase in input concentration.
[[Page 27]]
(v) Fall time: The time interval between initial response and 95
percent of final response after a step decrease in input concentration.
(vi) Precision: Variation about the mean of repeated measurements of
the same pollutant concentration, expressed as one standard deviation
about the mean.
(2) Tests for these performance parameters shall be accomplished
over a period of seven (7) or more days. During this time, the line
voltage supplied to the test analyzer and the ambient temperature
surrounding the analyzer shall be varied from day to day. One test
result for each performance parameter shall be obtained each test day,
for seven (7) or fifteen (15) test days as necessary. The tests are
performed sequentially in a single procedure.
(3) The 24-hour test day may begin at any clock hour. The first 12
hours out of each test day are required for testing 12-hour zero drift.
Tests for the other parameters shall be conducted during the remaining
12 hours.
(4) Table B-4 specifies the line voltage and room temperature to be
used for each test day. The line voltage and temperature shall be
changed to the specified values at the start of each test day (i.e., at
the start of the 12-hour zero test). Initial adjustments (day zero)
shall be made at a line voltage of 115 volts (rms) and a room
temperature of 25 deg.C.
(5) The tests shall be conducted in blocks consisting of 3 test days
each until 7 or 15 test results have been obtained. (The final block may
contain fewer than three test days.) If a test is interrupted by an
occurrence other than a malfunction of the test analyzer, only the block
during which the interruption occurred shall be repeated.
(6) During each block, manual adjustments to the electronics, gas,
or reagent flows or periodic maintenance shall not be permitted.
Automatic adjustments which the test analyzer performs by itself are
permitted at any time.
(7) At least 4 hours prior to the start of the first test day of
each block, the test analyzer may be adjusted and/or serviced according
to the periodic maintenance procedures specified in the manual referred
to in Sec. 53.4(b)(3). If a new block is to immediately follow a
previous block, such adjustments or servicing may be done immediately
after completion of the day's tests for the last day of the previous
block and at the voltage and temperature specified for that day, but
only on test days 3, 6, 9, and 12.
Note: If necessary, the beginning of the test days succeeding such
maintenance or adjustment may be delayed as necessary to complete the
service or adjustment operation.
(8) All response readings to be recorded shall first be converted to
concentration units according to the calibration curve. Whenever a test
atmosphere is to be measured but a stable reading is not required, the
test atmosphere shall be measured long enough to cause a change in
response of at least 10% of full scale. Identify all readings and other
pertinent data on the strip chart. (See Figure B-1 illustrating the
pattern of the required readings.)

(xxx) Measure test atmosphere A0 and record the stable
reading as L2.
(xxxi) Measure test atmosphere A80 and record the stable
reading as P11.
(xxxii) Sample test atmosphere A90; a stable reading is
not required.
(xxxiii) Measure test atmosphere A80 and record the
stable reading as P12.
(xxxiv) Repeat steps (viii) through (xxxiii) of this section, each
test day.
(xxxv) If zero and span adjustments are made after the readings are
taken on test days 3, 6, 9, or 12, complete all adjustments; then
measure test atmospheres A0, A80, and A20.
Allow for a stable reading on each, and record the readings as
Z'nS'n, and Mn respectively, where n =
the test day number.
(10) Determine the results of each day's tests as follows. Mark the
recorder chart to show readings and determinations.
(i) Zero drift. (A) 12-hour. Examine the strip chart pertaining to
the 12-
[[Page 31]]
hour continuous zero air test. Determine the minimum (Cmin.) and maximum
(Cmax.) readings (in p/m) during this period of 12 consecutive hours,
extrapolating the calibration curve to negative concentration units if
necessary. Determine the 12-hour zero drift (12ZD) as 12ZD =
Cmax.-Cmin.. (See Figure B-5 in appendix A.)
(B) Calculate the 24-hour zero drift (24ZD) for the n-th test day as
24ZDn = Zn-Zn-1, or 24ZDn =
Zn-Z'n-1 if zero adjustment was made on the
previous day, where Zn = \1/2\(L1+L2)
for L1 and L2 taken on the n-th test day.
(C) Compare 12ZD and 24ZD to the zero drift specification in table
B-1. Both 12ZD and 24ZD must be equal to or less than the specified
value to pass the test for zero drift.
(ii) Span drift. (A) Span drift at 20 percent of URL (MSD)

specifications given in table B-1 to pass the test for span draft.
(iii) Lag time. Determine, from the strip chart, the elapsed time in
minutes between the mark made in step (xxvi) and the first observable
(two times the noise level) response. This time must be equal to or less
than the time specified in table B-1 to pass the test for lag time.
(iv) Rise time. Calculate 95 percent of reading P9 and
determine from the recorder chart, the elapsed time between the first
observable (two times noise level) response and a response equal to 95
percent of the P9 reading. This time must be equal to or less
than the rise time specified in table B-1 to pass the test for rise
time.
(v) Fall time. Calculate five percent of (P10-
L2) and determine, from the strip chart, the elapsed time in
minutes between the first observable decrease in response following
reading P10 and a response equal to five percent of
(P10-L2). This time must be equal to or less than
the fall time specification in table B-1 to pass the test for fall time.

Subpart C--Procedures for Determining Comparability Between Candidate
Methods and Reference Methods
Source: 62 FR 38792, July 18, 1997, unless otherwise noted.
Sec. 53.30 General provisions.
(a) Determination of comparability. The test procedures prescribed
in this subpart shall be used to determine if a candidate method is
comparable to a reference method when both methods measure pollutant
concentrations in ambient air.
[[Page 38]]
(1) Comparability is shown for SO2, CO, O3,
and NO2 methods when the differences between:
(i) Measurements made by a candidate manual method or by a test
analyzer representative of a candidate automated method.
(ii) Measurements made simultaneously by a reference method, are
less than or equal to the values specified in the last column of table
C-1 of this subpart.
(2) Comparability is shown for lead methods when the differences
between:
(i) Measurements made by a candidate method.
(ii) Measurements made by the reference method on simultaneously
collected lead samples (or the same sample, if applicable), are less
than or equal to the value specified in table C-3 of this subpart.
(3) Comparability is shown for PM10 and PM2.5
methods when the relationship between:
(i) Measurements made by a candidate method.
(ii) Measurements made by a reference method on simultaneously
collected samples (or the same sample, if applicable) at each of two
test sites, is such that the linear regression parameters (slope,
intercept, and correlation coefficient) describing the relationship meet
the values specified in table C-4 of this subpart.
(b) Selection of test sites--(1) All methods. Each test site shall
be in a predominately urban area which can be shown to have at least
moderate concentrations of various pollutants. The site shall be clearly
identified and shall be justified as an appropriate test site with
suitable supporting evidence such as maps, population density data,
vehicular traffic data, emission inventories, pollutant measurements
from previous years, concurrent pollutant measurements, and
meteorological data. If approval of a proposed test site is desired
prior to conducting the tests, a written request for approval of the
test site or sites must be submitted prior to conducting the tests and
must include the supporting and justification information required. The
Administrator may exercise discretion in selecting a different site (or
sites) for any additional tests the Administrator decides to conduct.
(2) Methods for SO2, CO, O3, and
NO2. All test measurements are to be made at the same test
site. If necessary, the concentration of pollutant in the sampled
ambient air may be augmented with artificially generated pollutant to
facilitate measurements in the specified ranges described under
paragraph (d)(2) of this section.
(3) Methods for Pb. Test measurements may be made at any number of
test sites. Augmentation of pollutant concentrations is not permitted,
hence an appropriate test site or sites must be selected to provide lead
concentrations in the specified range.
(4) Methods for PM10. Test measurements must be made, or
derived from particulate samples collected, at not less than two test
sites, each of which must be located in a geographical area
characterized by ambient particulate matter that is significantly
different in nature and composition from that at the other test site(s).
Augmentation of pollutant concentrations is not permitted, hence
appropriate test sites must be selected to provide PM10
concentrations in the specified range. The tests at the two sites may be
conducted in different calendar seasons, if appropriate, to provide
PM10 concentrations in the specified ranges.
(5) Methods for PM2.5. Augmentation of pollutant
concentrations is not permitted, hence appropriate test sites must be
selected to provide PM2.5 concentrations and
PM2.5/PM10 ratios (if applicable) in the specified
ranges.
(i) Where only one test site is required, as specified in table C-4
of this subpart, the site need only meet the PM2.5 ambient
concentration levels required by Sec. 53.34(c)(3).
(ii) Where two sites are required, as specified in table C-4 of this
subpart, each site must be selected to provide the ambient concentration
levels required by Sec. 53.34(c)(3). In addition, one site must be
selected such that all acceptable test sample sets, as defined in
Sec. 53.34(c)(3), have a PM2.5/PM10 ratio of more
than 0.75; the other site must be selected such that all acceptable test
sample sets, as defined in Sec. 53.34(c)(3), have a PM2.5/
PM10 ratio of less than 0.40. At least two reference method
[[Page 39]]
PM10 samplers shall be collocated with the candidate and
reference method PM2.5 samplers and operated simultaneously
with the other samplers at each test site to measure concurrent ambient
concentrations of PM10 to determine the PM2.5/
PM10 ratio for each sample set. The PM2.5/
PM10 ratio for each sample set shall be the average of the
PM2.5 concentration, as determined in Sec. 53.34(c)(1),
divided by the average PM10 concentration, as measured by the
PM10 samplers. The tests at the two sites may be conducted in
different calendar seasons, if appropriate, to provide PM2.5
concentrations and PM2.5/PM10 ratios in the
specified ranges.
(c) Test atmosphere. Ambient air sampled at an appropriate test site
or sites shall be used for these tests. Simultaneous concentration
measurements shall be made in each of the concentration ranges specified
in tables C-1, C-3, or C-4 of this subpart, as appropriate.
(d) Sample collection--(1) All methods. All test concentration
measurements or samples shall be taken in such a way that both the
candidate method and the reference method receive air samples that are
homogenous or as nearly identical as practical.
(2) Methods for SO2, CO, O3, and
NO2. Ambient air shall be sampled from a common intake and
distribution manifold designed to deliver homogenous air samples to both
methods. Precautions shall be taken in the design and construction of
this manifold to minimize the removal of particulates and trace gases,
and to ensure that identical samples reach the two methods. If
necessary, the concentration of pollutant in the sampled ambient air may
be augmented with artificially-generated pollutant. However, at all
times the air sample measured by the candidate and reference methods
under test shall consist of not less than 80 percent ambient air by
volume. Schematic drawings, physical illustrations, descriptions, and
complete details of the manifold system and the augmentation system (if
used) shall be submitted.
(3) Methods for Pb, PM10 and PM2.5. The
ambient air intake points of all the candidate and reference method
collocated samplers for lead, PM10 or PM2.5 shall
be positioned at the same height above the ground level, and between 2
and 4 meters apart. The samplers shall be oriented in a manner that will
minimize spatial and wind directional effects on sample collection.
(4) PM10 methods employing the same sampling procedure as
the reference method but a different analytical method. Candidate
methods for PM10 which employ a sampler and sample collection
procedure that are identical to the sampler and sample collection
procedure specified in the reference method, but use a different
analytical procedure, may be tested by analyzing common samples. The
common samples shall be collected according to the sample collection
procedure specified by the reference method and shall be analyzed in
accordance with the analytical procedures of both the candidate method
and the reference method.
(e) Submission of test data and other information. All recorder
charts, calibration data, records, test results, procedural descriptions
and details, and other documentation obtained from (or pertinent to)
these tests shall be identified, dated, signed by the analyst performing
the test, and submitted. For candidate methods for PM2.5, all
submitted information must meet the requirements of the ANSI/ASQC E4
Standard, sections 3.3.1, paragraphs 1 and 2 (reference 1 of appendix A
of this subpart).
Sec. 53.31 Test conditions.
(a) All methods. All test measurements made or test samples
collected by means of a sample manifold as specified in Sec. 53.30(d)(2)
shall be at a room temperature between 20 deg.C and 30 deg.C, and at a
line voltage between 105 and 125 volts. All methods shall be calibrated
as specified in paragraph (c) of this section prior to initiation of the
tests.
(b) Samplers and automated methods. (1) Setup and start-up of the
test analyzer, test sampler(s), and reference method (if applicable)
shall be in strict accordance with the applicable operation manual(s).
If the test analyzer does not have an integral strip chart or digital
data recorder, connect the analyzer output to a suitable strip chart or
digital data recorder. This recorder shall have a chart width of at
least 25
[[Page 40]]
centimeters, a response time of 1 second or less, a deadband of not more
than 0.25 percent of full scale, and capability of either reading
measurements at least 5 percent below zero or offsetting the zero by at
least 5 percent. Digital data shall be recorded at appropriate time
intervals such that trend plots similar to a strip chart recording may
be constructed with a similar or suitable level of detail.
(2) Other data acquisition components may be used along with the
chart recorder during the conduct of these tests. Use of the chart
recorder is intended only to facilitate visual evaluation of data
submitted.
(3) Allow adequate warmup or stabilization time as indicated in the
applicable operation manual(s) before beginning the tests.
(c) Calibration. The reference method shall be calibrated according
to the appropriate appendix to part 50 of this chapter (if it is a
manual method) or according to the applicable operation manual(s) (if it
is an automated method). A candidate manual method (or portion thereof)
shall be calibrated, according to the applicable operation manual(s), if
such calibration is a part of the method.
(d) Range. (1) Except as provided in paragraph (d)(2) of this
section, each method shall be operated in the range specified for the
reference method in the appropriate appendix to part 50 of this chapter
(for manual reference methods), or specified in table B-1 of subpart B
of this part (for automated reference methods).
(2) For a candidate method having more than one selectable range,
one range must be that specified in table B-1 of subpart B of this part
and a test analyzer representative of the method must pass the tests
required by this subpart while operated on that range. The tests may be
repeated for a broader range (i.e., one extending to higher
concentrations) than the one specified in table B-1 of subpart B of this
part, provided that the range does not extend to concentrations more
than two times the upper range limit specified in table B-1 of subpart B
of this part and that the test analyzer has passed the tests required by
subpart B of this part (if applicable) for the broader range. If the
tests required by this subpart are conducted or passed only for the
range specified in table B-1 of subpart B of this part, any equivalent
method determination with respect to the method will be limited to that
range. If the tests are passed for both the specified range and a
broader range (or ranges), any such determination will include the
broader range(s) as well as the specified range. Appropriate test data
shall be submitted for each range sought to be included in such a
determination.
(e) Operation of automated methods. (1) Once the test analyzer has
been set up and calibrated and tests started, manual adjustment or
normal periodic maintenance as specified in the manual referred to in
Sec. 53.4(b)(3) is permitted only every 3 days. Automatic adjustments
which the test analyzer performs by itself are permitted at any time.
The submitted records shall show clearly when manual adjustments were
made and describe the operations performed.
(2) All test measurements shall be made with the same test analyzer;
use of multiple test analyzers is not permitted. The test analyzer shall
be operated continuously during the entire series of test measurements.
(3) If a test analyzer should malfunction during any of these tests,
the entire set of measurements shall be repeated, and a detailed
explanation of the malfunction, remedial action taken, and whether
recalibration was necessary (along with all pertinent records and
charts) shall be submitted.
Sec. 53.32 Test procedures for methods for SO2, CO, O3, and NO2.
(a) Conduct the first set of simultaneous measurements with the
candidate and reference methods:
(1) Table C-1 of this subpart specifies the type (1- or 24-hour) and
number of measurements to be made in each of the three test
concentration ranges.
(2) The pollutant concentration must fall within the specified range
as measured by the reference method.
(3) The measurements shall be made in the sequence specified in
table C-2 of this subpart, except for the 1-hour SO2
measurements, which are all in the high range.
[[Page 41]]
(b) For each pair of measurements, determine the difference
(discrepancy) between the candidate method measurement and reference
method measurement. A discrepancy which exceeds the discrepancy
specified in table C-1 of this subpart constitutes a failure. Figure C-1
of this subpart contains a suggested format for reporting the test
results.
(c) The results of the first set of measurements shall be
interpreted as follows:
(1) Zero failures. The candidate method passes the test for
comparability.
(2) Three or more failures. The candidate method fails the test for
comparability.
(3) One or two failures. Conduct a second set of simultaneous
measurements as specified in table C-1 of this subpart. The results of
the combined total of first-set and second-set measurements shall be
interpreted as follows:
(i) One or two failures. The candidate method passes the test for
comparability.
(ii) Three or more failures. The candidate method fails the test for
comparability.
(4) For SO2, the 1-hour and 24-hour measurements shall be
interpreted separately, and the candidate method must pass the tests for
both 1- and 24-hour measurements to pass the test for comparability.
(d) A 1-hour measurement consists of the integral of the
instantaneous concentration over a 60-minute continuous period divided
by the time period. Integration of the instantaneous concentration may
be performed by any appropriate means such as chemical, electronic,
mechanical, visual judgment, or by calculating the mean of not less than
12 equally spaced instantaneous readings. Appropriate allowances or
corrections shall be made in cases where significant errors could occur
due to characteristic lag time or rise/fall time differences between the
candidate and reference methods. Details of the means of integration and
any corrections shall be submitted.
(e) A 24-hour measurement consists of the integral of the
instantaneous concentration over a 24-hour continuous period divided by
the time period. This integration may be performed by any appropriate
means such as chemical, electronic, mechanical, or by calculating the
mean of 24 sequential 1-hour measurements.
(f) For ozone and carbon monoxide, no more than six 1-hour
measurements shall be made per day. For sulfur dioxide, no more than
four 1-hour measurements or one 24-hour measurement shall be made per
day. One-hour measurements may be made concurrently with 24-hour
measurements if appropriate.
(g) For applicable methods, control or calibration checks may be
performed once per day without adjusting the test analyzer or method.
These checks may be used as a basis for a linear interpolation-type
correction to be applied to the measurements to correct for drift. If
such a correction is used, it shall be applied to all measurements made
with the method, and the correction procedure shall become a part of the
method.
Sec. 53.33 Test procedure for methods for lead.
(a) Sample collection. Collect simultaneous 24-hour samples
(filters) of lead at the test site or sites with both the reference and
candidate methods until at least 10 filter pairs have been obtained. If
the conditions of Sec. 53.30(d)(4) apply, collect at least 10 common
samples (filters) in accordance with Sec. 53.30(d)(4) and divide each to
form the filter pairs.
(b) Audit samples. Three audit samples must be obtained from the
address given in Sec. 53.4(a). The audit samples are 3/4x8-inch glass
fiber strips containing known amounts of lead at the following nominal
levels: 100 [mu]g/strip; 300 [mu]g/strip; 750 [mu]g/strip. The true
amount of lead, in total [mu]g/strip, will be provided with each audit
sample.
(c) Filter analysis. (1) For both the reference method samples and
the audit samples, analyze each filter extract three times in accordance
with the reference method analytical procedure. The analysis of
replicates should not be performed sequentially, i.e., a single sample
should not be analyzed three
[[Page 42]]
times in sequence. Calculate the indicated lead concentrations for the
reference method samples in [mu]g/m3 for each analysis of
each filter. Calculate the indicated total lead amount for the audit
samples in [mu]g/strip for each analysis of each strip. Label these test
results as R1A, R1B, R1C,
R2A, R2B, ..., Q1A, Q1B,
Q1C, ..., where R denotes results from the reference method
samples; Q denotes results from the audit samples; 1, 2, 3 indicate the
filter number, and A, B, C indicate the first, second, and third
analysis of each filter, respectively.
(2) For the candidate method samples, analyze each sample filter or
filter extract three times and calculate, in accordance with the
candidate method, the indicated lead concentrates in [mu]g/m3
for each analysis of each filter. Label these test results as
C1A, C1B, C2C, ..., where C denotes
results from the candidate method. For candidate methods which provide a
direct measurement of lead concentrations without a separable procedure,
C1A = C1B = C1C, C2A =
C2B = C2C, etc.
(d) Average lead concentration. For the reference method, calculate
the average lead concentration for each filter by averaging the
concentrations calculated from the three analyses:
Equation 1
[GRAPHIC] [TIFF OMITTED] TR18JY97.052
where:
i is the filter number.
(e) Acceptable filter pairs. Disregard all filter pairs for which
the lead concentration as determined in the previous paragraph (d) of
this section by the average of the three reference method
determinations, falls outside the range of 0.5 to 4.0 [mu]g/
m3. All remaining filter pairs must be subjected to both of
the following tests for precision and comparability. At least five
filter pairs must be within the 0.5 to 4.0 [mu]g/m3 range for
the tests to be valid.
(f) Test for precision. (1) Calculate the precision (P) of the
analysis (in percent) for each filter and for each method, as the
maximum minus the minimum divided by the average of the three
concentration values, as follows:
Equation 2
[GRAPHIC] [TIFF OMITTED] TR18JY97.053
or
Equation 3
[GRAPHIC] [TIFF OMITTED] TR18JY97.054
where:
i indicates the filter number.
(2) If any reference method precision value (PRi) exceeds
15 percent, the precision of the reference method analytical procedure
is out of control. Corrective action must be taken to determine the
source(s) of imprecision and the reference method determinations must be
repeated according to paragraph (c) of this section, or the entire test
procedure (starting with paragraph (a) of this section) must be
repeated.
(3) If any candidate method precision value (PCi) exceeds
15 percent, the candidate method fails the precision test.
(4) The candidate method passes this test if all precision values
(i.e., all PRi's and all PCi's) are less than 15
percent.
(g) Test for accuracy. (1)(i) For the audit samples calculate the
average lead concentration for each strip by averaging the
concentrations calculated from the three analyses:
Equation 4
[GRAPHIC] [TIFF OMITTED] TR18JY97.055
where:
i is audit sample number.
(ii) Calculate the percent difference (Dq) between the
indicated lead concentration for each audit sample and the true lead
concentration (Tq) as follows:
[[Page 43]]
Equation 5
[GRAPHIC] [TIFF OMITTED] TR18JY97.056
(2) If any difference value (Dqi) exceeds 5
percent, the accuracy of the reference method analytical procedure is
out of control. Corrective action must be taken to determine the source
of the error(s) (e.g., calibration standard discrepancies, extraction
problems, etc.) and the reference method and audit sample determinations
must be repeated according to paragraph (c) of this section, or the
entire test procedure (starting with paragraph (a) of this section) must
be repeated.
(h) Test for comparability. (1) For each filter pair, calculate all
nine possible percent differences (D) between the reference and
candidate methods, using all nine possible combinations of the three
determinations (A, B, and C) for each method, as:
Equation 6
[GRAPHIC] [TIFF OMITTED] TR18JY97.057
where:
i is the filter number, and n numbers from 1 to 9 for the nine possible
difference combinations for the three determinations for each method
(j = A, B, C, candidate; k = A, B, C, reference).
(2) If none of the percent differences (D) exceeds 20
percent, the candidate method passes the test for comparability.
(3) If one or more of the percent differences (D) exceeds
20 percent, the candidate method fails the test for
comparability.
(i) The candidate method must pass both the precision test
(paragraph (f) of this section) and the comparability test (paragraph
(h) of this section) to qualify for designation as an equivalent method.
Sec. 53.34 Test procedure for methods for PM10 and PM2.5.
(a) Collocated measurements. Set up three reference method samplers
collocated with three candidate method samplers or analyzers at each of
the number of test sites specified in table C-4 of this subpart. At each
site, obtain as many sets of simultaneous PM10 or
PM2.5 measurements as necessary (see paragraph (c)(3) of this
section), each set consisting of three reference method and three
candidate method measurements, all obtained simultaneously. For
PM2.5 candidate Class II equivalent methods, at least two
collocated PM10 reference method samplers are also required
to obtain PM2.5/PM10 ratios for each sample set.
Candidate PM10 method measurements shall be 24-hour
integrated measurements; PM2.5 measurements may be either 24-
or 48-hour integrated measurements. All collocated measurements in a
sample set must cover the same 24- or 48-hour time period. For samplers,
retrieve the samples promptly after sample collection and analyze each
sample according to the reference method or candidate method, as
appropriate, and determine the PM10 or PM2.5
concentration in [mu]g/m3. If the conditions of
Sec. 53.30(d)(4) apply, collect sample sets only with the three
reference method samplers. Guidance for quality assurance procedures for
PM2.5 methods is found in section 2.12 of the Quality
Assurance Handbook (reference 6 of appendix A to subpart A of this
part).
(b) Sequential samplers. For sequential samplers, the sampler shall
be configured for the maximum number of sequential samples and shall be
set for automatic collection of all samples sequentially such that the
test samples are collected equally, to the extent possible, among all
available sequential channels or utilizing the full available sequential
capability.
(c) Test for comparability and precision. (1) For each of the
measurement sets, calculate the average PM10 or
PM2.5 concentration obtained with the reference method
samplers:
Equation 7
[GRAPHIC] [TIFF OMITTED] TR18JY97.058
where:
[[Page 44]]
R denotes results from the reference method;
i is the sampler number; and
j is the set.
(2)(i) For each of the measurement sets, calculate the precision of
the reference method PM10 or PM2.5 measurements
as:
Equation 8
[GRAPHIC] [TIFF OMITTED] TR18JY97.059
If the corresponding Rj is below:

(3) If Rj falls outside the acceptable concentration
range specified in table C-4 of this subpart for any set, or if
Pj RPj as applicable, exceeds the value specified
in table C-4 of this subpart for any set, that set of measurements shall
be discarded. For each site, table C-4 of this subpart specifies the
minimum number of sample sets required for various conditions, and
Sec. 53.30(b)(5) specifies the PM2.5/PM10 ratio
requirements applicable to Class II candidate equivalent methods.
Additional measurement sets shall be collected and analyzed, as
necessary, to provide a minimum of 10 acceptable measurement sets for
each test site. If more than 10 measurement sets are collected that meet
the above criteria, all such measurement sets shall be used to
demonstrate comparability.
(4) For each of the acceptable measurement sets, calculate the
average PM10 or PM2.5 concentration obtained with
the candidate method samplers:
Equation 10
[GRAPHIC] [TIFF OMITTED] TR18JY97.061
where:
C denotes results from the candidate method;
i is the sampler number; and
j is the set.
(5) For each site, plot the average PM10 or
PM2.5 measurements obtained with the candidate method
(Rj) against the corresponding average PM10 or
PM2.5 measurements obtained with the reference method
(Rj). For each site, calculate and record the linear
regression slope and intercept, and the correlation coefficient.
(6) If the linear regression parameters calculated under paragraph
(c)(5) of this section meet the values specified in table C-4 of this
subpart for all test sites, the candidate method passes the test for
comparability.

Subpart D--Procedures for Testing Performance Characteristics of Methods
for PM10
Source: 52 FR 24729, July 1, 1987, unless otherwise noted.
Sec. 53.40 General provisions.
(a) The test procedures prescribed in this subpart shall be used to
test the performance of candidate methods for PM10 against
the performance specifications given in table D-1. Except as provided in
paragraph (b) of this section, a test sampler or samplers representative
of the sampler described in the candidate method must exhibit
performance better than, or equal to, the specified value for each
performance parameter, to satisfy the requirements of this subpart.
(b) For a candidate method using a PM10 sampler
previously approved as part of a designated PM10 method, only
the test for precision need be conducted and passed to satisfy the
requirements of this subpart. For a candidate method using a
PM10 sampler inlet previously approved as part of a
designated PM10 method, the tests for precision and flow rate
stability must be conducted and passed to satisfy the requirements of
this subpart; the tests for sampling effectiveness and 50 percent
cutpoint need not be conducted if suitable rationale is provided to
demonstrate that test results submitted for the previously approved
method are applicable to the candidate method.
(c) The liquid particle sampling effectiveness and 50 percent
cutpoint of a test sampler shall be determined in a wind tunnel using 10
particle sizes and three wind speeds as specified in table D-2. A
minimum of 3 replicate measurements of sampling effectiveness shall be
required for each of the 30 test conditions for a minimum of 90 test
measurements.
(d) For the liquid particle sampling effectiveness parameter, a
smooth
[[Page 48]]
curve plot shall be constructed of sampling effectiveness (percent)
versus aerodynamic particle diameter ([mu]m) for each of the three wind
speeds. These plots shall be used to calculate the expected mass
concentration for the test sampler, using the procedure in
Sec. 53.43(a). The candidate method passes the liquid particle sampling
effectiveness test if the expected mass concentration calculated for the
test sampler at each wind speed differs by no more than 10
percent from that predicted for the ``ideal'' sampler.*
---------------------------------------------------------------------------
* The sampling effectiveness curve for this ``ideal'' sampler is
described by column 5 of table D-3 and is based on a model that
approximates the penetration of particles into the human respiratory
tract. Additional information on this model may be found in a document
entitled, ``Particle Collection Criteria for 10 Micrometer Samplers,''
which is available from the Quality Assurance Division (MD-77),
Environmental Monitoring Systems Laboratory, U.S. Environmental
Protection Agency, Research Triangle Park, NC 27711.
---------------------------------------------------------------------------
(e) For the 50 percent cutpoint parameter, the test result for each
wind speed shall be reported as the particle size at which the curve
specified in Sec. 53.40(d) crosses the 50 percent effectiveness line.
The candidate method passes the 50 percent cutpoint test if the test
result at each wind speed falls within 100.5 [mu]m.
(f) The solid particle sampling effectiveness of a test sampler
shall be determined in a wind tunnel using 25 [mu]m particles at 2 wind
speeds as specified in table D-2. A minimum of three replicate
measurements of sampling effectiveness for the 25 [mu]m solid particles
shall be required at both wind speeds for a minimum of 6 test
measurements.
(g) For the solid particle sampling effectiveness parameter, the
test result for each wind speed shall be reported as the difference
between the average of the replicate sampling effectiveness measurements
obtained for the 25 [mu]m solid particles and the average of the
replicate measurements obtained for the 25 [mu]m liquid particles. The
candidate method passes the solid particle sampling effectiveness test
if the test result for each wind speed is less than, or equal to, 5
percent.
(h) The precision and flow rate stability of three identical test
samplers shall be determined at a suitable test site by simultaneously
sampling the PM10 concentration of the atmosphere for 10
periods of 24 hours.
(i) For the precision parameter, the test result for each of the 10
periods of 24 hours shall be calculated using the procedure in
Sec. 53.43(c). The candidate method passes the precision test if all of
the test results meet the specifications in table D-1.
(j) For the flow rate stability parameter, the test results for each
of the three test samplers and for each of the 10 periods of 24 hours
shall be calculated using the procedure in Sec. 53.43(d). The candidate
method passes the flow rate stability test if all of the test results
meet the specifications in table D-1.
(k) All test data and other documentation obtained from or pertinent
to these tests shall be identified, dated, signed by the analyst
performing the test, and submitted to EPA.

Sec. 53.41 Test conditions.
(a) Set-up and start-up of all test samplers shall be in strict
accordance with the operating instructions specified in the manual
referred to in Sec. 53.4(b)(3).
(b) If the internal surface or surfaces of the candidate method's
sampler inlet on which the particles removed by the inlet are collected
is a dry surface (i.e., not normally coated with oil or grease), those
surfaces shall be cleaned prior to conducting wind tunnel tests with
solid particles.
(c) Once the test sampler or samplers have been set up and the
performance tests started, manual adjustment shall be permitted only
between test points for the sampling effectiveness and 50 percent
cutpoint tests or between test days for the precision and flow rate
stability tests. The manual adjustments and any periodic maintenance
shall be limited to only those procedures prescribed in the manual
referred to in Sec. 53.4(b)(3). The submitted records shall show clearly
when any manual adjustment or periodic maintenance was made and shall
describe the operations performed.
(d) If a test sampler malfunctions during any of the sampling
effectiveness and 50 percent cutpoint tests, that test run shall be
repeated. If a test sampler malfunctions during any of the precision and
flow rate stability tests, that day's test shall be repeated. A detailed
explanation of all malfunctions and the remedial actions taken shall be
submitted to EPA with the application.
Sec. 53.42 Generation of test atmospheres for wind tunnel tests.
(a) A vibrating orifice aerosol generator shall be used to produce
monodispersed liquid particles of oleic acid tagged with uranine dye and
monodispersed solid particles of ammonium fluoroscein with equivalent
aerodynamic diameters as specified in table D-2. The geometric standard
deviation for each particle size and type generated shall not exceed 1.1
(for primary particles) and the proportion of multiplets (doublets and
triplets) in a test particle atmosphere shall not exceed 10 percent. The
particle delivery system shall consist of a blower system and a wind
tunnel having a test section of sufficiently large cross-sectional area
such that the test sampler, or portion thereof, as installed in the test
section for testing, blocks no more than 15 percent of that area. To be
acceptable, the blower system must be capable of achieving uniform wind
speeds at the speeds specified in table D-2.

combination of particle size and wind speed): 90.
Number of solid particle test points (minimum of 3 replicates for each
combination of particle size and wind speed): 6.
Total number of test points: 96.
(b) The size of the test particles delivered to the test section of
the wind tunnel shall be established using the operating parameters of
the vibrating orifice aerosol generator and shall be verified during the
tests by microscopic examination of samples of the particles collected
on glass slides or other suitable substrates. When sizing liquid
particles on glass slides, the slides should be pretreated with an
oleophobic surfactant and an appropriate flattening factor shall be used
in the calculation of aerodynamic diameter. The particle size, as
established by the operating parameters of the vibrating orifice aerosol
generator, shall be within the tolerance specified in table D-2. The
precision of the particle size verification technique shall be 0.5 [mu]m
or better, and particle size determined by the verification technique
shall not differ by more than 0.5 [mu]m or 10 percent, whichever is
higher, from that established by the operating parameters of the
vibrating orifice aerosol generator.
[[Page 50]]
(c) The population of multiplets in a test particle atmosphere shall
be determined during the tests and shall not exceed 10 percent. Solid
particles shall be checked for dryness and evidence of breakage or
agglomeration during the microscopic examination. If the solid particles
in a test atmosphere are wet or show evidence of significant breakage or
agglomeration ([mu]5 percent), the solid particle test atmosphere is
unacceptable for purposes of these tests.
(d) The concentration of particles in the wind tunnel is not
critical. However, the cross-sectional uniformity of the particle
concentration in the sampling zone of the test section shall be
established during the tests using isokinetic samplers. An array of not
less than five evenly spaced isokinetic samplers shall be used to
determine the particle concentration uniformity in the sampling zone. If
the particle concentration measured by any single isokinetic sampler in
the sampling zone differs by more than 10 percent from the mean
concentration, the particle delivery system is unacceptable in terms of
uniformity of particle concentration. The sampling zone shall be a
rectangular area having a horizontal dimension not less than 1.2 times
the width of the test sampler at its inlet opening and a vertical
dimension not less than 25 centimeters. The sampling zone is an area in
the test section of the wind tunnel that is horizontally and vertically
symmetrical with respect to the test sampler inlet opening.
(e) The wind speed in the wind tunnel shall be determined during the
tests using an appropriate technique capable of a precision of 5 percent
or better (e.g., hot-wire anemometry). The mean wind speed in the test
section of the wind tunnel during the tests shall be within 10 percent
of the value specified in table D-2. The wind speed measured at any test
point in the test section shall not differ by more than 10 percent from
the mean wind speed in the test section. The turbulence intensity
(longitudinal component and macroscale) in the test section shall be
determined during the tests using an appropriate technique (e.g., hot-
wire anemometry).
(f) The accuracy of all flow measurements used to calculate the test
atmosphere concentrations and the test results shall be documented to be
within 2 percent, referenced to a primary standard. Any flow
measurement corrections shall be clearly shown. All flow measurements
shall be given in actual volumetric units.
(g) Schematic drawings of the particle delivery system (wind tunnel
and blower system) and other information showing complete procedural
details of the test atmosphere generation, verification, and delivery
techniques shall be submitted to EPA. All pertinent calculations shall
be clearly presented.
Sec. 53.43 Test procedures.
(a) Sampling effectiveness--(1) Technical definition. The ratio
(expressed as a percentage) of the mass concentration of particles of a
given size reaching the sampler filter or filters to the mass
concentration of particles of the same size approaching the sampler.
(2) Test procedure. (i) Establish a wind speed specified in table D-
2 and measure the wind speed and turbulence intensity (longitudinal
component and macroscale) at a minimum of 12 test points in a cross-
sectional area of the test section of the wind tunnel. The mean wind
speed in the test section must be within 10 percent of the
value specified in table D-2 and the variation at any test point in the
test section may not exceed 10 percent of the mean.
(ii) Generate particles of a size and type specified in table D-2
using a vibrating orifice aerosol generator. Check for the presence of
satellites and adjust the generator as necessary. Calculate the
aerodynamic particle size using the operating parameters of the
vibrating orifice aerosol generator and record. The calculated
aerodynamic diameter must be within the tolerance specified in table D-
2.
(iii) Collect a sample of the particles on a glass slide or other
suitable substrate at the particle injection point. If a glass slide is
used, it should be pretreated with an appropriate oleophobic surfactant
when collecting liquid particles. Use a microscopic technique to size a
minimum of 25 primary particles in three viewing fields (do not include
multiplets). Determine
[[Page 51]]
the geometric mean aerodynamic diameter and geometric standard deviation
using the bulk density of the particle type (and an appropriate
flattening factor for liquid particles if collected on a glass slide).
The measured geometric mean aerodynamic diameter must be within 0.5
[mu]m or 10 percent of the aerodynamic diameter calculated from the
operating parameters of the vibrating orifice aerosol generator. The
geometric standard deviation must not exceed 1.1.
(iv) Determine the population of multiplets (doublets and triplets)
in the collected sample by counting a minimum of 100 particles in three
viewing fields. The multiplet population of the particle test atmosphere
must not exceed 10 percent.
(v) Introduce the particles into the wind tunnel and allow the
particle concentration to stabilize.
(vi) Install an array of five or more evenly spaced isokinetic
samplers in the sampling zone (see Sec. 53.42(d)) of the wind tunnel.
Collect particles on appropriate filters (e.g., glass fiber) over a time
period such that the relative error of the measured particle
concentration is less than 5 percent. Relative error is defined as
(px100%)/(X), where p is the precision of the fluorometer on the
appropriate range, X is the measured concentration, and the units of p
and X are the same.
(vii) Determine the quantity of material collected with each
isokinetic sampler in the array using a calibrated fluorometer.
Calculate and record the mass concentration for each isokinetic sampler
as:
[GRAPHIC] [TIFF OMITTED] TC09NO91.015
where
i = replicate number and j = isokinetic sampler number.
(viii) Calculate and record the mean mass concentration as:
[GRAPHIC] [TIFF OMITTED] TC09NO91.016
where
n = total number of isokinetic samplers.
(ix) Calculate and record the coefficient of variation of the mass
concentration measurements as:
[GRAPHIC] [TIFF OMITTED] TC09NO91.017
If the value of CViso(i) exceeds 0.10, the particle
concentration uniformity is unacceptable and steps (vi) through (ix)
must be repeated. If adjustment of the vibrating orifice aerosol
generator or changes in the particle delivery system are necessary to
achieve uniformity, steps (ii) through (ix) must be repeated. Remove the
array of isokinetic samplers from the wind tunnel. NOTE: A single
isokinetic sampler, operated at the same nominal flow rate as the test
sampler, may be used in place of the array of isokinetic samplers for
the determination of particle mass concentration used in the calculation
of
[[Page 52]]
sampling effectiveness of the test sampler in step (xiii). In this case,
the array of isokinetic samplers must be used to demonstrate particle
concentration uniformity prior to the replicate measurements of sampling
effectiveness.
(x) If a single isokinetic sampler is used, install the sampler in
the wind tunnel with the sampler nozzle centered in the sampling zone
(see Sec. 53.42(d)). Collect particles on an appropriate filter (e.g.,
glass fiber) for a time period such that the relative error of the
measured concentration (as defined in step (vi)) is less than 5 percent.
Determine the quantity of material collected with the isokinetic sampler
using a calibrated fluorometer. Calculate and record the mass
concentration as Ciso(i) as in step vii. Remove the
isokinetic sampler from the wind tunnel.
(xi) Install the test sampler (or portion thereof) in the wind
tunnel with the sampler inlet opening centered in the sampling zone (see
Sec. 53.42(d)). To meet the maximum blockage limit of Sec. 53.42(a) or
for convenience, part of the test sampler may be positioned external to
the wind tunnel provided that neither the geometry of the sampler nor
the length of any connecting tube or pipe is altered. Collect particles
on an appropriate filter or filters (e.g., glass fiber) for a time
period such that the relative error of the measured concentration (as
defined in step (vi)) is less than 5 percent.
(xii) Determine the quantity of material collected with the test
sampler using a calibrated fluorometer. Calculate and record the mass
concentration as:
[GRAPHIC] [TIFF OMITTED] TC09NO91.018
where i=replicate number.
(xiii) Calculate and record the sampling effectiveness of the test
sampler as:
[GRAPHIC] [TIFF OMITTED] TC09NO91.019
where i = replicate number.
Note: If a single isokinetic sampler is used for the determination
of particle mass concentration, replace Ciso(i) with
Ciso(i).
(xiv) Remove the test sampler from the wind tunnel. Repeat steps
(vi) through (xiii), as appropriate, to obtain a minimum of three
replicate measurements of sampling effectiveness.
(xv) Calculate and record the average sampling effectiveness of the
test sampler as:
[GRAPHIC] [TIFF OMITTED] TC09NO91.020
where n=number of replicates.
(xvi) Calculate and record the coefficient of variation for the
replicate sampling effectiveness measurements of the test sampler as:
[GRAPHIC] [TIFF OMITTED] TC09NO91.021
If the value of CVE exceeds 0.10, the test run (steps (ii)
through (xvi)) must be repeated.
(xvii) Repeat steps i through xvi for each wind speed, particle
size, and particle type specified in table D-2.
(xviii) For each of the three wind speeds (nominally 2, 8, and 24
km/hr), correct the liquid particle sampling effectiveness data for the
presence of multiplets (doublets and triplets) in the test particle
atmospheres.
(xix) For each wind speed, plot the corrected liquid particle
sampling effectiveness of the test sampler (Ecorr) as a
function of particle size (dp) on semi-logarithmic graph
paper where dp is the
[[Page 53]]
particle size established by the operating parameters of the vibrating
orifice aerosol generator. Construct a smooth curve through the data.
(xx) For each wind speed, calculate the expected mass concentration
for the test sampler under the assumed particle size distribution and
compare it to the mass concentration predicted for the ideal sampler, as
follows:
(A) Extrapolate the upper and lower ends of the corrected liquid
particle sampling effectiveness curve to 100 percent and 0 percent,
respectively, using smooth curves. Assume that Ecorr = 100
percent at a particle size of 1.0 [mu]m and Ecorr = 0 percent
at a particle size of 50 [mu]m.
(B) Determine the value of Ecorr at each of the particle
sizes specified in the first column of table D-3. Record each
Ecorr value as a decimal between 0 and 1 in the second column
of table D-3.
(C) Multiply the values of Ecorr in column 2 by the
interval mass concentration values in column 3 and enter the products in
column 4 of table D-3.
(D) Sum the values in column 4 and enter the total as the expected
mass concentration for the test sampler at the bottom of column 4 of
table D-3.
(E) Calculate and record the percent difference in expected mass
concentration between the test sampler and the ideal sampler as:
[GRAPHIC] [TIFF OMITTED] TC09NO91.022
where:
Csam(exp) = expected mass concentration for the test sampler,
[mu]g/m\3\
Cideal(exp) = expected mass concentration for the ideal
sampler, [mu]g/m\3\ (calculated for the ideal sampler and given at the
bottom of column 7 of table D-3.)
(F) The candidate method passes the liquid particle sampling
effectiveness test if the [Delta] C value for each wind speed meets the
specification in table D-1.
(xxi) For each of the two wind speeds (nominally 8 and 24 km/hr),
calculate the difference between the average sampling effectiveness
value for the 25 [mu]m solid particles and the average sampling
effectiveness value for the 25 [mu]m liquid particles (uncorrected for
multiplets).
(xxii) The candidate method passes the solid particle sampling
effectiveness test if each such difference meets the specification in
table D-1.

(b) 50 Percent cutpoint--(1) Technical definition. The particle size
for which the sampling effectiveness of the sampler is 50 percent.
(2) Test procedure. (i) From the corrected liquid particle sampling
effectiveness curves for each of the three wind speeds, determine the
particle size at which the curve crosses the 50 percent effectiveness
line and record as D50 on the corresponding sampling
effectiveness plot.
(ii) The candidate method passes the 50 percent cutpoint test if the
D50 value at each wind speed meets the specification in table
D-1.
(c) Precision--(1) Technical definition. The variation in the
measured particle concentration among identical samplers under typical
sampling conditions.
(2) Test procedure. (i) Set up three identical test samplers at the
test site in strict accordance with the instructions in the manual
referred to in Sec. 53.4(b)(3). Locate the test sampler inlet openings
at the same height and between 2 and 4 meters apart. The samplers shall
be oriented in a manner that will minimize spatial and wind directional
effects on sample collection. Perform a flow calibration for each test
sampler in accordance with the instructions given in the instruction
manual and/or appendix J to part 50 of this chapter. Set the operating
flow rate to the value prescribed in the sampler instruction manual.
Note: For candidate equivalent methods, this test may be used to
satisfy part of the requirements of subpart C of this chapter. In that
case, three reference method samplers are also used at the test site,
measurements with the candidate and reference methods are compared as
specified in Sec. 53.34, and the test site must meet the requirements of
Sec. 53.30(b).
(ii) Measure the PM10 concentration of the atmosphere
using the three test samplers for 10 periods (test days) of 24 hours
each. On each of the 10 test days, measure the initial and final flow
rates of each test sampler. On three of the test days, measure the flow
rate of each test sampler after 6, 12, and 18 hours of operation. All
measurements of flow rate and mass collected must be made in accordance
with the procedures prescribed in the sampler instruction manual and/or
appendix J to part 50 of this chapter. All measurements of flow rate
must be in actual volumetric units. Record the PM10
concentration for each sampler and each test day as C(i)(j)
where i is the sampler number and j is the test day.
(iii) For each test day, calculate and record the average of the
three measured PM10 concentrations as C(j) where j
is the test day. If C(j)<30 [mu] g/m\3\ for any test day,
data from that test day are unacceptable and the tests for that day must
be repeated.
[[Page 55]]
(iv) Calculate and record the precision for each of the 10 test days
as:
(v) The candidate method passes the precision test if all 10
Pj or RPj values meet the specifications in table
D-1.
(d) Flow rate stability--(1) Technical definition. Freedom from
variation in the operating flow rate of the sampler under typical
sampling conditions.
(2) Test procedure. (i) For each of the three test samplers and each
of the 10 test days of the precision test, record each measured flow
rate as F(i)(j)(t), where i is the sampler number, j is the
test day, and t is the time of flow rate measurement (t=0, 6, 12, 18, or
24 hours).
(ii) For each sampler and for each test day, calculate and record
the average flow rate as:
where n = number of flow rate measurements during the 24-hour test day.
(iii) For each sampler and for each test day, calculate and record
the percent difference between the average flow rate and the initial
flow rate as:
where F(i)(j)(0) is the initial flow rate (t=0).
(iv) For each sampler and for each of the 3 test days on which flow
measurements were obtained at 6-hour intervals throughout the 24-hour
sampling period, calculate and record the percent differences between
each measured flow rate and the initial flow rate as:
where t = 6, 12, 18, or 24 hours.
(v) The candidate method passes the flow rate stability test if all
of the [Delta] F(i)(j) and [Delta] F(i)(j)(t)
values meet the specifications in table D-1.
Subpart E--Procedures for Testing Physical (Design) and Performance
Characteristics of Reference Methods and Class I Equivalent Methods for
PM2.5
Source: 62 FR 38799, July 18, 1997, unless otherwise noted.
Sec. 53.50 General provisions.
(a) This subpart sets forth the specific tests that must be carried
out and the test results, evidence, documentation, and other materials
that must be
[[Page 56]]
provided to EPA to demonstrate that a PM2.5 sampler
associated with a candidate reference method or Class I equivalent
method meets all design and performance specifications set forth in 40
CFR part 50, appendix L, as well as additional requirements specified in
this subpart E. Some of these tests may also be applicable to portions
of a candidate Class II equivalent method sampler, as determined under
subpart F of this part. Some or all of these tests may also be
applicable to a candidate Class III equivalent method sampler, as may be
determined under Sec. 53.3(a)(4) or Sec. 53.3(b)(3).
(b) Samplers associated with candidate reference methods for
PM2.5 shall be subject to the provisions, specifications, and
test procedures prescribed in Secs. 53.51 through 53.58. Samplers
associated with candidate Class I equivalent methods for
PM2.5 shall be subject to the provisions, specifications, and
test procedures prescribed in all sections of this subpart. Samplers
associated with candidate Class II equivalent methods for
PM2.5 shall be subject to the provisions, specifications, and
test procedures prescribed in all applicable sections of this subpart,
as specified in subpart F of this part.
(c) The provisions of Sec. 53.51 pertain to test results and
documentation required to demonstrate compliance of a candidate method
sampler with the design specifications set forth in 40 CFR part 50,
appendix L. The test procedures prescribed in Secs. 53.52 through 53.59
pertain to performance tests required to demonstrate compliance of a
candidate method sampler with the performance specifications set forth
in 40 CFR part 50, appendix L, as well as additional requirements
specified in this subpart E. These latter test procedures shall be used
to test the performance of candidate samplers against the performance
specifications and requirements specified in each procedure and
summarized in table E-1 of this subpart.
(d) Test procedures prescribed in Sec. 53.59 do not apply to
candidate reference method samplers. These procedures apply primarily to
candidate Class I equivalent method samplers for PM2.5 which
have a sample air flow path configuration upstream of the sample filter
that is modified with respect to that specified for the reference method
sampler, as set forth in 40 CFR part 50, appendix L, figures L-1 to L-
29, such as might be necessary to provide for sequential sample
capability. The additional tests determine the adequacy of aerosol
transport through any altered components or supplemental devices that
are used in a candidate sampler upstream of the sample filter. In
addition to the other test procedures in this subpart, these test
procedures shall be used to further test the performance of such an
equivalent method sampler against the performance specifications given
in the procedure and summarized in table E-1 of this subpart.
(e) A 10-day operational field test of measurement precision is
required under Sec. 53.58 for both candidate reference and equivalent
method samplers. This test requires collocated operation of three
candidate method samplers at a field test site. For candidate equivalent
method samplers, this test may be combined and carried out concurrently
with the test for comparability to the reference method specified under
Sec. 53.34, which requires collocated operation of three reference
method samplers and three candidate equivalent method samplers.
(f) All tests and collection of test data shall be performed in
accordance with the requirements of reference 1, section 4.10.5 (ISO
9001) and reference 2, part B, section 3.3.1, paragraphs 1 and 2 and
part C, section 4.6 (ANSI/ASQC E4) in appendix A of this subpart. All
test data and other documentation obtained specifically from or
pertinent to these tests shall be identified, dated, signed by the
analyst performing the test, and submitted to EPA in accordance with
subpart A of this part.
Sec. 53.51 Demonstration of compliance with design specifications and manufacturing and test requirements.
(a) Overview. (1) The subsequent paragraphs of this section specify
certain documentation that must be submitted and tests that are required
to demonstrate that samplers associated with a designated reference or
equivalent method for PM2.5 are properly manufactured to meet
all applicable design and
[[Page 57]]
performance specifications and have been properly tested according to
all applicable test requirements for such designation. Documentation is
required to show that instruments and components of a PM2.5
sampler are manufactured in an ISO 9001-registered facility under a
quality system that meets ISO-9001 requirements for manufacturing
quality control and testing.
(2) In addition, specific tests are required to verify that two
critical features of reference method samplers impactor jet diameter and
the surface finish of surfaces specified to be anodized meet the
specifications of 40 CFR part 50, appendix L. A checklist is required to
provide certification by an ISO-certified auditor that all performance
and other required tests have been properly and appropriately conducted,
based on a reasonable and appropriate sample of the actual operations or
their documented records. Following designation of the method, another
checklist is required, initially and annually, to provide an ISO-
certified auditor's certification that the sampler manufacturing process
is being implemented under an adequate and appropriate quality system.
(3) For the purposes of this section, the definitions of ISO 9001-
registered facility and ISO-certified auditor are found in Sec. 53.1. An
exception to the reliance by EPA on ISO-certified auditors is the
requirement for the submission of the operation or instruction manual
associated with the candidate method to EPA as part of the application.
This manual is required under Sec. 53.4(b)(3). EPA has determined that
acceptable technical judgment for review of this manual may not be
assured by ISO-certified auditors, and approval of this manual will
therefore be performed by EPA.
(b) ISO registration of manufacturing facility. (1) The applicant
must submit documentation verifying that the samplers identified and
sold as part of a designated PM2.5 reference or equivalent
method will be manufactured in an ISO 9001-registered facility and that
the manufacturing facility is maintained in compliance with all
applicable ISO 9001 requirements (reference 1 in appendix A of this
subpart). The documentation shall indicate the date of the original ISO
9001 registration for the facility and shall include a copy of the most
recent certification of continued ISO 9001 facility registration. If the
manufacturer does not wish to initiate or complete ISO 9001 registration
for the manufacturing facility, documentation must be included in the
application to EPA describing an alternative method to demonstrate that
the facility meets the same general requirements as required for
registration to ISO-9001. In this case, the applicant must provide
documentation in the application to demonstrate, by required ISO-
certified auditor's inspections, that a quality system is in place which
is adequate to document and monitor that the sampler system components
and final assembled samplers all conform to the design, performance and
other requirements specified in this part and in 40 CFR part 50,
appendix L.
(2) Phase-in period. For a period of 1 year following the effective
date of this subpart, a candidate reference or equivalent method for
PM2.5 that utilizes a sampler manufactured in a facility that
is not ISO 9001-registered or otherwise approved by EPA under paragraph
(b)(1) of this section may be conditionally designated as a reference or
equivalent method under this part. Such conditional designation will be
considered on the basis of evidence submitted in association with the
candidate method application showing that appropriate efforts are
currently underway to seek ISO 9001 registration or alternative approval
of the facility's quality system under paragraph (b)(1) of this section
within the next 12 months. Such conditional designation shall expire 1
year after the date of the Federal Register notice of the conditional
designation unless documentation verifying successful ISO 9001
registration for the facility or other EPA-acceptable quality system
review and approval process of the production facility that will
manufacture the samplers is submitted at least 30 days prior to the
expiration date.
(c) Sampler manufacturing quality control. The manufacturer must
ensure that all components used in the manufacture of PM2.5
samplers to be sold as part of a reference or equivalent method and that
are specified by design in
[[Page 58]]
40 CFR part 50, appendix L, are fabricated or manufactured exactly as
specified. If the manufacturer's quality records show that its quality
control (QC) and quality assurance (QA) system of standard process
control inspections (of a set number and frequency of testing that is
less than 100 percent) complies with the applicable QA provisions of
section 4 of reference 4 in appendix A of this subpart and prevents
nonconformances, 100 percent testing shall not be required until that
conclusion is disproved by customer return or other independent
manufacturer or customer test records. If problems are uncovered,
inspection to verify conformance to the drawings, specifications, and
tolerances shall be performed. Refer also to paragraph (e) of this
section--final assembly and inspection requirements.
(d) Specific tests and supporting documentation required to verify
conformance to critical component specifications--(1) Verification of
PM2.5 impactor jet diameter. The diameter of the jet of each
impactor manufactured for a PM2.5 sampler under the impactor
design specifications set forth in 40 CFR part 50, appendix L, shall be
verified against the tolerance specified on the drawing, using standard,
NIST-traceable ZZ go/no go plug gages. This test shall be a final check
of the jet diameter following all fabrication operations, and a record
shall be kept of this final check. The manufacturer shall submit
evidence that this procedure is incorporated into the manufacturing
procedure, that the test is or will be routinely implemented, and that
an appropriate procedure is in place for the disposition of units that
fail this tolerance test.
(2) Verification of surface finish. The anodization process used to
treat surfaces specified to be anodized shall be verified by testing
treated specimen surfaces for weight and corrosion resistance to ensure
that the coating obtained conforms to the coating specification. The
specimen surfaces shall be finished in accordance with military standard
specification 8625F, Type II, Class I (reference 4 in appendix A of this
subpart) in the same way the sampler surfaces are finished, and tested,
prior to sealing, as specified in section 4.5.2 of reference 4 in
appendix A of this subpart.
(e) Final assembly and inspection requirements. Each sampler shall
be tested after manufacture and before delivery to the final user. Each
manufacturer shall document its post-manufacturing test procedures. As a
minimum, each test shall consist of the following: Tests of the overall
integrity of the sampler, including leak tests; calibration or
verification of the calibration of the flow measurement device,
barometric pressure sensor, and temperature sensors; and operation of
the sampler with a filter in place over a period of at least 48 hours.
The results of each test shall be suitably documented and shall be
subject to review by an ISO-certified auditor.
(f) Manufacturer's audit checklists. Manufacturers shall require an
ISO-certified auditor to sign and date a statement indicating that the
auditor is aware of the appropriate manufacturing specifications
contained in 40 CFR part 50, appendix L, and the test or verification
requirements in this subpart. Manufacturers shall also require an ISO-
certified auditor to complete the checklists, shown in figures E-1 and
E-2 of this subpart, which describe the manufacturer's ability to meet
the requirements of the standard for both designation testing and
product manufacture.
(1) Designation testing checklist. The completed statement and
checklist as shown in figure E-1 of this subpart shall be submitted with
the application for reference or equivalent method determination.
(2) Product manufacturing checklist. Manufacturers shall require an
ISO-certified auditor to complete a Product Manufacturing Checklist
(figure E-2 of this subpart), which evaluates the manufacturer on its
ability to meet the requirements of the standard in maintaining quality
control in the production of reference or equivalent devices. The
initial completed checklist shall be submitted with the application for
reference or equivalent method determination. Also, this checklist
(figure E-2 of this subpart) must be completed and submitted annually to
retain a reference or equivalent method designation for a
PM2.5 method.
[[Page 59]]
(3) Phase-in period. If the conditions of paragraph (b)(2) of this
section apply, a candidate reference or equivalent method for
PM2.5 may be conditionally designated as a reference or
equivalent method under this part 53 without the submission of the
checklists described in paragraphs (f)(1) and (f)(2) of this section.
Such conditional designation shall expire 1 year after the date of the
Federal Register notice of the conditional designation unless the
checklists are submitted at least 30 days prior to the expiration date.
[62 FR 38799, July 18, 1997; 63 FR 7714, Feb. 17, 1998]
Sec. 53.52 Leak check test.
(a) Overview. In section 7.4.6 of 40 CFR part 50, appendix L, the
sampler is required to include the facility, including components,
instruments, operator controls, a written procedure, and other
capabilities as necessary, to allow the operator to carry out a leak
test of the sampler at a field monitoring site without additional
equipment. This test procedure is intended to test the adequacy and
effectiveness of the sampler's leak check facility. Because of the
variety of potential sampler configurations and leak check procedures
possible, some adaptation of this procedure may be necessary to
accommodate the specific sampler under test. The test conditions and
performance specifications associated with this test are summarized in
table E-1 of this subpart. The candidate test sampler must meet all test
parameters and test specifications to successfully pass this test.
(b) Technical definitions. (1) External leakage includes the total
flow rate of external ambient air which enters the sampler other than
through the sampler inlet and which passes through any one or more of
the impactor, filter, or flow rate measurement components.
(2) Internal leakage is the total sample air flow rate that passes
through the filter holder assembly without passing through the sample
filter.
(c) Required test equipment. (1) Flow rate measurement device, range
70 mL/min to 130 mL/min, 2 percent certified accuracy, NIST-traceable.
(2) Flow rate measurement adaptor (40 CFR part 50, appendix L,
figure L-30) or equivalent adaptor to facilitate measurement of sampler
flow rate at the top of the downtube.
(3) Impermeable membrane or disk, 47 mm nominal diameter.
(4) Means, such as a micro-valve, of providing a simulated leak flow
rate through the sampler of approximately 80 mL/min under the conditions
specified for the leak check in the sampler's leak check procedure.
(5) Teflon sample filter, as specified in section 6 of 40 CFR part
50, appendix L.
(d) Calibration of test measurement instruments. Submit
documentation showing evidence of appropriately recent calibration,
certification of calibration accuracy, and NIST-traceability (if
required) of all measurement instruments used in the tests. The accuracy
of flow rate meters shall be verified at the highest and lowest
pressures and temperatures used in the tests and shall be checked at
zero and one or more non-zero flow rates within 7 days of use for this
test.
(e) Test setup. (1) The test sampler shall be set up for testing as
described in the sampler's operation or instruction manual referred to
in Sec. 53.4(b)(3). The sampler shall be installed upright and set up in
its normal configuration for collecting PM2.5 samples, except
that the sample air inlet shall be removed and the flow rate measurement
adaptor shall be installed on the sampler's downtube.
(2) The flow rate control device shall be set up to provide a
constant, controlled flow rate of 80 mL/min into the sampler downtube
under the conditions specified for the leak check in the sampler's leak
check procedure.
(3) The flow rate measurement device shall be set up to measure the
controlled flow rate of 80 mL/min into the sampler downtube under the
conditions specified for the leak check in the sampler's leak check
procedure.
(f) Procedure. (1) Install the impermeable membrane in a filter
cassette and install the cassette into the sampler. Carry out the
internal leak check procedure as described in the sampler's operation/
instruction manual and verify that the leak check acceptance
[[Page 60]]
criterion specified in table E-1 of this subpart is met.
(2) Replace the impermeable membrane with a Teflon filter and
install the cassette in the sampler. Remove the inlet from the sampler
and install the flow measurement adaptor on the sampler's downtube.
Close the valve of the adaptor to seal the flow system. Conduct the
external leak check procedure as described in the sampler's operation/
instruction manual and verify that the leak check acceptance criteria
specified in table E-1 of this subpart are met.
(3) Arrange the flow control device, flow rate measurement device,
and other apparatus as necessary to provide a simulated leak flow rate
of 80 mL/min into the test sampler through the downtube during the
specified external leak check procedure. Carry out the external leak
check procedure as described in the sampler's operation/instruction
manual but with the simulated leak of 80 mL/min.
(g) Test results. The requirements for successful passage of this
test are:
(1) That the leak check procedure indicates no significant external
or internal leaks in the test sampler when no simulated leaks are
introduced.
(2) That the leak check procedure properly identifies the occurrence
of the simulated external leak of 80 mL/min.
Sec. 53.53 Test for flow rate accuracy, regulation, measurement accuracy, and cut-off.
(a) Overview. This test procedure is designed to evaluate a
candidate sampler's flow rate accuracy with respect to the design flow
rate, flow rate regulation, flow rate measurement accuracy, coefficient
of variability measurement accuracy, and the flow rate cut-off function.
The tests for the first four parameters shall be conducted over a 6-hour
time period during which reference flow measurements are made at
intervals not to exceed 5 minutes. The flow rate cut-off test, conducted
separately, is intended to verify that the sampler carries out the
required automatic sample flow rate cut-off function properly in the
event of a low-flow condition. The test conditions and performance
specifications associated with this test are summarized in table E-1 of
this subpart. The candidate test sampler must meet all test parameters
and test specifications to successfully pass this test.
(b) Technical definitions. (1) Sample flow rate means the
quantitative volumetric flow rate of the air stream caused by the
sampler to enter the sampler inlet and pass through the sample filter,
measured in actual volume units at the temperature and pressure of the
air as it enters the inlet.
(2) The flow rate cut-off function requires the sampler to
automatically stop sample flow and terminate the current sample
collection if the sample flow rate deviates by more than the variation
limits specified in table E-1 of this subpart (10 percent
from the nominal sample flow rate) for more than 60 seconds during a
sample collection period. The sampler is also required to properly
notify the operator with a flag warning indication of the out-of-
specification flow rate condition and if the flow rate cut-off results
in an elapsed sample collection time of less than 23 hours.
(c) Required test equipment. (1) Flow rate meter, suitable for
measuring and recording the actual volumetric sample flow rate at the
sampler downtube, with a minimum range of 10 to 25 L/min, 2 percent
certified, NIST-traceable accuracy. Optional capability for continuous
(analog) recording capability or digital recording at intervals not to
exceed 30 seconds is recommended. While a flow meter which provides a
direct indication of volumetric flow rate is preferred for this test, an
alternative certified flow measurement device may be used as long as
appropriate volumetric flow rate corrections are made based on
measurements of actual ambient temperature and pressure conditions.
(2) Ambient air temperature sensor, with a resolution of 0.1 deg.C
and certified to be accurate to within 0.5 deg.C (if needed). If the
certified flow meter does not provide direct volumetric flow rate
readings, ambient air temperature measurements must be made using
continuous (analog) recording capability or digital recording at
intervals not to exceed 5 minutes.
[[Page 61]]
(3) Barometer, range 600 mm Hg to 800 mm Hg, certified accurate to 2
mm Hg (if needed). If the certified flow meter does not provide direct
volumetric flow rate readings, ambient pressure measurements must be
made using continuous (analog) recording capability or digital recording
at intervals not to exceed 5 minutes.
(4) Flow measurement adaptor (40 CFR part 50, appendix L, figure L-
30) or equivalent adaptor to facilitate measurement of sample flow rate
at the sampler downtube.

sampler flow rate such that the sampler flow rate is decreased slowly
over several minutes to a flow rate slightly less than the flow rate
[[Page 62]]

zero and at least one flow rate within 3 percent of 16.7 L/
min within 7 days prior to use for this test. Where an instrument's
measurements are to be recorded with an analog recording device, the
accuracy of the entire instrument-recorder system shall be calibrated or
verified.
(e) Test setup. (1) Setup of the sampler shall be performed as
required in this paragraph (e) and otherwise as described in the
sampler's operation or instruction manual referred to in
Sec. 53.4(b)(3). The sampler shall be installed upright and set up in
the pressure-controlled chamber in its normal configuration for
collecting PM2.5 samples. A sample filter and (or) the device
for creating an additional 55 mm Hg pressure drop shall be installed for
the duration of these tests. The sampler's ambient temperature, ambient
pressure, and flow measurement systems shall all be calibrated per the
sampler's operating manual within 7 days prior to this test.
[[Page 70]]
(2) The inlet of the candidate sampler shall be removed and the flow
measurement adaptor installed on the sampler's downtube. A leak check as
described in the sampler's operation or instruction manual shall be
conducted and must be properly passed before other tests are carried
out.
(3) The inlet of the flow measurement adaptor shall be connected to
the outlet of the flow rate meter.
(4) The barometer shall be installed in the test chamber such that
it will accurately measure the air pressure to which the candidate

(f) Procedure. (1) Set up the sampler as specified in paragraph (e)
of this section and otherwise prepare the sampler for normal sample
collection operation as directed in the sampler's operation or
instruction manual.
(2) The test shall consist of two test runs, one at each of the
following conditions of chamber pressure:
(i) 600 mm Hg.
(ii) 800 mm Hg.
(3) For each of the two test runs, set the selected chamber pressure
for the test run. Upon achieving each pressure setpoint in the chamber,
the candidate sampler shall be pressure-equilibrated for a period of at
least 30 minutes prior to the test run. Following the conditioning time,
set the sampler to automatically start a 6-hour sample collection period
at a convenient time.
(4) During each 6-hour test period:
(i) Measure and record the sample flow rate with the flow rate meter
at intervals not to exceed 5 minutes. If ambient temperature and

ambient temperature and pressure shall be measured at the same frequency
as that of the certified flow rate measurements. Note and record the
actual start and stop times for the 6-hour flow rate test period.
(ii) Determine and record the ambient (chamber) pressure indicated

not automatically terminated by the sampler) and download all archived
instrument data for the test run from the test sampler.
(g) Test results. For each of the two test runs, examine the chamber
pressure measurements. Verify that the pressure met the requirements
specified in paragraph (f) of this section at all times during the test.
If not, the test run is not valid and must be repeated. Determine the
test results as follows:
(1) Mean sample flow rate. (i) From the certified measurements
(Qref) of the test sampler flow rate, tabulate each flow rate
measurement in units of L/min. If ambient temperature and pressure
corrections are necessary to calculate volumetric flow rate, each
measured flow rate shall be corrected using its corresponding
temperature and pressure measurement values. Calculate the mean flow
rate for the sample period (Qref,ave) as follows:
Equation 17
[GRAPHIC] [TIFF OMITTED] TR18JY97.079
where:

[GRAPHIC] [TIFF OMITTED] TR18JY97.083
(ii) To successfully pass this test, the absolute difference in
values calculated in Equation 21 of this paragraph (g)(4) must not
exceed 0.3 (CV%) for each test run.
(5) Ambient pressure measurement accuracy. (i) Calculate the
absolute difference between the mean ambient air pressure indicated by
the test sampler and the ambient (chamber) air pressure measured with
the reference barometer as:
Equation 22
[GRAPHIC] [TIFF OMITTED] TR18JY97.084
where:
Pind,ave = mean ambient pressure indicated by the test
sampler, mm Hg; and
Pref,ave = mean barometric pressure measured by the reference
barometer, mm Hg.

Sec. 53.57 Test for filter temperature control during sampling and post-sampling periods.
(a) Overview. This test is intended to measure the candidate
sampler's ability to prevent excessive overheating of the
PM2.5 sample collection filter (or filters) under conditions
of elevated solar insolation. The test evaluates radiative effects on
filter temperature during a 4-hour period of active sampling as well as
during a subsequent 4-hour non-sampling time period prior to filter
retrieval. Tests shall be conducted in an environmental chamber which
provides the proper radiant wavelengths and energies to adequately
simulate the sun's radiant effects under clear conditions at sea level.
For additional guidance on conducting solar radiative tests under
controlled conditions, consult military standard specification 810-E
(reference 6 in appendix A of this subpart). The performance parameters
tested under this procedure, the corresponding minimum performance
specifications, and the applicable test conditions are summarized in
table E-1 of this subpart. Each performance parameter tested, as
described or determined in the test procedure, must meet or exceed the
associated performance specification to successfully pass this test.
(b) Technical definition. Filter temperature control during sampling
is the ability of a sampler to maintain the temperature of the
particulate matter sample filter within the specified deviation (5
deg.C) from ambient temperature during any active sampling period.
[[Page 72]]
Post-sampling temperature control is the ability of a sampler to
maintain the temperature of the particulate matter sample filter within
the specified deviation from ambient temperature during the period from
the end of active sample collection of the PM2.5 sample by
the sampler until the filter is retrieved from the sampler for
laboratory analysis.
(c) Required test equipment. (1) Environmental chamber providing the
means, such as a bank of solar-spectrum lamps, for generating or
simulating thermal radiation in approximate spectral content and
intensity equivalent to solar insolation of 1000 50 W/
m2 inside the environmental chamber. To properly simulate the
sun's radiative effects on the sampler, the solar bank must provide the
spectral energy distribution and permitted tolerances specified in table
E-2 of this subpart. The solar radiation source area shall be such that
the width of the candidate sampler shall not exceed one-half the
dimensions of the solar bank. The solar bank shall be located a minimum
of 76 cm (30 inches) from any surface of the candidate sampler. To meet
requirements of the solar radiation tests, the chamber's internal volume
shall be a minimum of 10 times that of the volume of the candidate
sampler. Air velocity in the region of the sampler must be maintained
continuously during the radiative tests at 2.0 0.5 m/sec.
(2) Ambient air temperature recorder, range -30 deg.C to =50
deg.C, with a resolution of 0.1 deg.C and certified accurate to within
0.5 deg.C. Ambient air temperature measurements must be made using
continuous (analog) recording capability or digital recording at
intervals not to exceed 5 minutes.
(3) Flow measurement adaptor (40 CFR part 50, appendix L, figure L-
30) or equivalent adaptor to facilitate measurement of sampler flow rate
at the sampler downtube.
(4) Miniature temperature sensor(s), capable of being installed in
the sampler without introducing air leakage and capable of measuring the
sample air temperature within 1 cm of the center of the filter,
downstream of the filter; with a resolution of 0.1 deg.C, certified
accurate to within 0.5 deg.C, NIST-traceable, with continuous (analog)
recording capability or digital recording at intervals of not more than
5 minutes.
(5) Solar radiometer, to measure the intensity of the simulated
solar radiation in the test environment, range of 0 to approximately
1500 W/m2. Optional capability for continuous (analog)
recording or digital recording at intervals not to exceed 5 minutes is
recommended.
(6) Sample filter or filters, as specified in section 6 of 40 CFR
part 50, appendix L.
(d) Calibration of test measurement instruments. Submit
documentation showing evidence of appropriately recent calibration,
certification of calibration accuracy, and NIST-traceability (if
required) of all measurement instruments used in the tests. The accuracy
of flow rate meters shall be verified at the highest and lowest
pressures and temperatures used in the tests and shall be checked at
zero and at least one flow rate within 3 percent of 16.7 L/
min within 7 days prior to use for this test. Where an instrument's
measurements are to be recorded with an analog recording device, the
accuracy of the entire instrument-recorder system shall be calibrated or
verified.
(e) Test setup. (1) Setup of the sampler shall be performed as
required in this paragraph (e) and otherwise as described in the
sampler's operation or instruction manual referred to in
Sec. 53.4(b)(3). The sampler shall be installed upright and set up in
the solar radiation environmental chamber in its normal configuration
for collecting PM2.5 samples (with the inlet installed). The
sampler's ambient and filter temperature measurement systems shall be
calibrated per the sampler's operating manual within 7 days prior to
this test. A sample filter shall be installed for the duration of this
test. For sequential samplers, a sample filter shall also be installed
in each available sequential channel or station intended for collection
of a sequential sample (or at least 5 additional filters for magazine-
type sequential samplers) as directed by the sampler's operation or
instruction manual.
(2) The miniature temperature sensor shall be temporarily installed
in the test sampler such that it accurately
[[Page 73]]
measures the air temperature 1 cm from the center of the filter on the
downstream side of the filter. The sensor shall be installed such that
no external or internal air leakage is created by the sensor
installation. The sensor's dimensions and installation shall be selected
to minimize temperature measurement uncertainties due to thermal
conduction along the sensor mounting structure or sensor conductors. For
sequential samplers, similar temperature sensors shall also be
temporarily installed in the test sampler to monitor the temperature 1
cm from the center of each filter stored in the sampler for sequential
sample operation.
(3) The solar radiant energy source shall be installed in the test
chamber such that the entire test sampler is irradiated in a manner
similar to the way it would be irradiated by solar radiation if it were
located outdoors in an open area on a sunny day, with the radiation
arriving at an angle of between 30 deg. and 45 deg. from vertical. The
intensity of the radiation received by all sampler surfaces that receive
direct radiation shall average 1000 50 W/m2,
measured in a plane perpendicular to the incident radiation. The
incident radiation shall be oriented with respect to the sampler such
that the area of the sampler's ambient temperature sensor (or
temperature shield) receives full, direct radiation as it would or could
during normal outdoor installation. Also, the temperature sensor must
not be shielded or shaded from the radiation by a sampler part in a way
that would not occur at other normal insolation angles or directions.
(4) The solar radiometer shall be installed in a location where it
measures thermal radiation that is generally representative of the
average thermal radiation intensity that the upper portion of the
sampler and sampler inlet receive. The solar radiometer shall be
oriented so that it measures the radiation in a plane perpendicular to
its angle of incidence.
(5) The ambient air temperature recorder shall be installed in the
test chamber such that it will accurately measure the temperature of the
air in the chamber without being unduly affected by the chamber's air
temperature control system or by the radiant energy from the solar
radiation source that may be present inside the test chamber.
(f) Procedure. (1) Set up the sampler as specified in paragraph (e)
of this section and otherwise prepare the sampler for normal sample
collection operation as directed in the sampler's operation or
instruction manual.
(2) Remove the inlet of the candidate test sampler and install the
flow measurement adaptor on the sampler's downtube. Conduct a leak check
as described in the sampler's operation or instruction manual. The leak
test must be properly passed before other tests are carried out.
(3) Remove the flow measurement adaptor from the downtube and re-
install the sampling inlet.
(4) Activate the solar radiation source and verify that the
resulting energy distribution prescribed in table E-2 of this subpart is
achieved.
(5) Program the test sampler to conduct a single sampling run of 4
continuous hours. During the 4-hour sampling run, measure and record the
radiant flux, ambient temperature, and filter temperature (all filter
temperatures for sequential samplers) at intervals not to exceed 5
minutes.
(6) At the completion of the 4-hour sampling phase, terminate the
sample period, if not terminated automatically by the sampler. Continue
to measure and record the radiant flux, ambient temperature, and filter
temperature or temperatures for 4 additional hours at intervals not to
exceed 5 minutes. At the completion of the 4-hour post-sampling period,
discontinue the measurements and turn off the solar source.
(7) Download all archived sampler data from the test run.
(g) Test results. Chamber radiant flux control. Examine the
continuous record of the chamber radiant flux and verify that the flux
met the requirements specified in table E-2 of this subpart at all times
during the test. If not, the entire test is not valid and must be
repeated.
(1) Filter temperature measurement accuracy. (i) For each 4-hour
test period,
[[Page 74]]
calculate the absolute value of the difference between the mean filter
temperature indicated by the sampler (active filter) and the mean filter
temperature measured by the reference temperature sensor installed
within 1 cm downstream of the (active) filter as:
Equation 23
[GRAPHIC] [TIFF OMITTED] TR18JY97.085
where:
Tind,filter = mean filter temperature indicated by the test
sampler, deg.C; and
Tref,filter = mean filter temperature measured by the
reference temperature sensor, deg.C.
(ii) To successfully pass the indicated filter temperature accuracy
test, the calculated difference between the measured means
(Tdiff,filter) must not exceed 2 deg.C for each 4-hour test
period.
(2) Ambient temperature measurement accuracy. (i) For each 4-hour
test period, calculate the absolute value of the difference between the
mean ambient air temperature indicated by the test sampler and the mean
ambient air temperature measured by the reference ambient air
temperature recorder as:
Equation 24
[GRAPHIC] [TIFF OMITTED] TR18JY97.086
where:
Tind,ambient = mean ambient air temperature indicated by the
test sampler, deg.C; and
Tref,ambient = mean ambient air temperature measured by the
reference ambient air temperature recorder, deg.C.
(ii) To successfully pass the indicated ambient temperature accuracy
test, the calculated difference between the measured means
(Tdiff,ambient) must not exceed 2 deg.C for each 4-hour test
period.
(3) Filter temperature control accuracy. (i) For each temperature
measurement interval over each 4-hour test period, calculate the
difference between the filter temperature indicated by the reference
temperature sensor and the ambient temperature indicated by the test
sampler as:
Equation 25
[GRAPHIC] [TIFF OMITTED] TR18JY97.087
(ii) Tabulate and inspect the calculated differences as a function
of time. To successfully pass the indicated filter temperature control
test, the calculated difference between the measured values must not
exceed 5 deg.C for any consecutive intervals covering more than a 30-
minute time period.
(iii) For sequential samplers, repeat the test calculations for each
of the stored sequential sample filters. All stored filters must also
meet the 5 deg.C temperature control test.

Sec. 53.58 Operational field precision and blank test.
(a) Overview. This test is intended to determine the operational
precision of the candidate sampler during a minimum of 10 days of field
operation, using three collocated test samplers. Measurements of
PM2.5 are made at a test site with all of the samplers and
then compared to determine replicate precision. Candidate sequential
samplers are also subject to a test for possible deposition of
particulate matter on inactive filters during a period of storage in the
sampler. This procedure is applicable to both reference and equivalent
methods. In the case of equivalent methods, this test may be combined
and conducted concurrently with the comparability test for equivalent
methods (described in subpart C of this part), using three reference
method samplers collocated with three candidate equivalent method
samplers and meeting the applicable site and other requirements of
subpart C of this part.
(b) Technical definition. (1) Field precision is defined as the
standard deviation or relative standard deviation of a set of
PM2.5 measurements obtained concurrently with three or more
collocated samplers in actual ambient air field operation.
(2) Storage deposition is defined as the mass of material
inadvertently deposited on a sample filter that is stored in a
sequential sampler either prior to or subsequent to the active sample
collection period.
(c) Test site. Any outdoor test site having PM2.5
concentrations that are reasonably uniform over the test area
[[Page 75]]
and that meet the minimum level requirement of paragraph (g)(2) of this
section is acceptable for this test.
(d) Required facilities and equipment. (1) An appropriate test site
and suitable electrical power to accommodate three test samplers are
required.
(2) Teflon sample filters, as specified in section 6 of 40 CFR part
50, appendix L, conditioned and preweighed as required by section 8 of
40 CFR part 50, appendix L, as needed for the test samples.
(e) Test setup. (1) Three identical test samplers shall be installed
at the test site in their normal configuration for collecting
PM2.5 samples in accordance with the instructions in the
associated manual referred to in Sec. 53.4(b)(3) and should be in
accordance with applicable supplemental guidance provided in reference 3
in appendix A of this subpart. The test samplers' inlet openings shall
be located at the same height above ground and between 2 and 4 meters
apart horizontally. The samplers shall be arranged or oriented in a
manner that will minimize the spatial and wind directional effects on
sample collection of one sampler on any other sampler.
(2) Each test sampler shall be successfully leak checked,
calibrated, and set up for normal operation in accordance with the
instruction manual and with any applicable supplemental guidance
provided in reference 3 in appendix A of this subpart.
(f) Test procedure. (1) Install a conditioned, preweighed filter in
each test sampler and otherwise prepare each sampler for normal sample
collection. Set identical sample collection start and stop times for
each sampler. For sequential samplers, install a conditioned, preweighed
specified filter in each available channel or station intended for
automatic sequential sample filter collection (or at least 5 additional
filters for magazine-type sequential samplers), as directed by the
sampler's operation or instruction manual. Since the inactive sequential
channels are used for the storage deposition part of the test, they may
not be used to collect the active PM2.5 test samples.
(2) Collect either a 24-hour or a 48-hour atmospheric
PM2.5 sample simultaneously with each of the three test
samplers.
(3) Following sample collection, retrieve the collected sample from
each sampler. For sequential samplers, retrieve the additional stored
(blank, unsampled) filters after at least 5 days (120 hours) storage in
the sampler if the active samples are 24-hour samples, or after at least
10 days (240 hours) if the active samples are 48-hour samples.
(4) Determine the measured PM2.5 mass concentration for
each sample in accordance with the applicable procedures prescribed for
the candidate method in appendix L, 40 CFR part 50 of this chapter, in
the associated manual referred to in Sec. 53.4(b)(3) and in accordance
with supplemental guidance in reference 2 in appendix A of this subpart.
For sequential samplers, also similarly determine the storage deposition
as the net weight gain of each blank, unsampled filter after the 5-day
(or 10-day) period of storage in the sampler.
(5) Repeat this procedure to obtain a total of 10 sets of any
combination of 24-hour or 48-hour PM2.5 measurements over 10
test periods. For sequential samplers, repeat the 5-day (or 10-day)
storage test of additional blank filters once for a total of two sets of
blank filters.
(g) Calculations. (1) Record the PM2.5 concentration for
each test sampler for each test period as Ci,j, where i is
the sampler number (i = 1,2,3) and j is the test period (j = 1,2, . . .
10).
(2)(i) For each test period, calculate and record the average of the
three measured PM2.5 concentrations as Cj where j
is the test period:
Equation 26
[GRAPHIC] [TIFF OMITTED] TR18JY97.088
(ii) If Cave,j < 10 [mu]g/m3 for any test
period, data from that test period are unacceptable, and an additional
sample collection set must be obtained to replace the unacceptable data.
(3)(i) Calculate and record the precision for each of the 10 test
days as:
[[Page 76]]
Equation 27
[GRAPHIC] [TIFF OMITTED] TR18JY97.089
(ii) If Cave,j is below 40 [mu]g/m3 for 24-
hour measurements or below 30 [mu]g/m3 for 48-hour
measurements; or
Equation 28
[GRAPHIC] [TIFF OMITTED] TR18JY97.090
(iii) If Cave,j is above 40 [mu]g/m3 for 24-
hour measurements or above 30 [mu]g/m3 for 48-hour
measurements.
(h) Test results. (1) The candidate method passes the precision test
if all 10 Pj or RPj values meet the specifications
in table E-1 of this subpart.
(2) The candidate sequential sampler passes the blank filter storage
deposition test if the average net storage deposition weight gain of
each set of blank filters (total of the net weight gain of each blank
filter divided by the number of filters in the set) from each test
sampler (six sets in all) is less than 50 [mu]g.
Sec. 53.59 Aerosol transport test for Class I equivalent method samplers.
(a) Overview. This test is intended to verify adequate aerosol
transport through any modified or air flow splitting components that may
be used in a Class I candidate equivalent method sampler such as may be
necessary to achieve sequential sampling capability. This test is
applicable to all Class I candidate samplers in which the aerosol flow

would normally connect.
(2) The test particle delivery system shall be connected to the
sampler downtube so that the test aerosol is introduced at the top of
the downtube.
(f) Test procedure. (1) All surfaces of the added or modified

Subpart F--Procedures for Testing Performance Characteristics of Class
II Equivalent Methods for PM2.5
Source: 62 FR 38814, July 18, 1997, unless otherwise noted.
Sec. 53.60 General provisions.
(a) This subpart sets forth the specific requirements that a
PM2.5 sampler associated with a candidate Class II equivalent
method must meet to be designated as an equivalent method for
PM2.5. This subpart also sets forth the explicit test
procedures that must be carried out and the test results, evidence,
documentation, and other materials that must be provided to EPA to
demonstrate that a sampler meets all specified requirements for
designation as an equivalent method.
(b) A candidate method described in an application for a reference
or equivalent method application submitted under Sec. 53.4 shall be
determined by the EPA to be a Class II candidate equivalent method on
the basis of the definition of a Class II equivalent method given in
Sec. 53.1.
(c) Any sampler associated with a Class II candidate equivalent
method
[[Page 81]]
(Class II sampler) must meet all requirements for reference method
samplers and Class I equivalent method samplers specified in subpart E
of this part, as appropriate. In addition, a Class II sampler must meet
the additional requirements as specified in paragraph (d) of this
section.
(d) Except as provided in paragraphs (d) (1), (2), and (3) of this
section, all Class II samplers are subject to the additional tests and
performance requirements specified in Sec. 53.62 (full wind tunnel
test), Sec. 53.65 (loading test), and Sec. 53.66 (volatility test).
Alternative tests and performance requirements, as described in
paragraphs (d)(1), (2), and (3) of this section, are optionally
available for certain Class II samplers which meet the requirements for
reference method or Class I samplers given in 40 CFR part 50, appendix
L, and in subpart E of this part, except for specific deviations of the
inlet, fractionator, or filter.
(1) Inlet deviation. A sampler which has been determined to be a
Class II sampler solely because the design or construction of its inlet
deviates from the design or construction of the inlet specified in 40
CFR part 50, appendix L, for reference method samplers shall not be
subject to the requirements of Sec. 53.62 (full wind tunnel test),
provided that it meets all requirements of Sec. 53.63 (wind tunnel inlet
aspiration test), Sec. 53.65 (loading test), and Sec. 53.66 (volatility
test).
(2) Fractionator deviation. A sampler which has been determined to
be a Class II sampler solely because the design or construction of its
particle size fractionator deviates from the design or construction of
the particle size fractionator specified in 40 CFR part 50, appendix L
for reference method samplers shall not be subject to the requirements
of Sec. 53.62 (full wind tunnel test), provided that it meets all
requirements of Sec. 53.64 (static fractionator test), Sec. 53.65
(loading test), and Sec. 53.66 (volatility test).
(3) Filter size deviation. A sampler which has been determined to be
a Class II sampler solely because its effective filtration area deviates
from that of the reference method filter specified in 40 CFR part 50,
appendix L, for reference method samplers shall not be subject to the
requirements of Sec. 53.62 (full wind tunnel test) nor Sec. 53.65
(loading test), provided it meets all requirements of Sec. 53.66
(volatility test).
(e) The test specifications and acceptance criteria for each test
are summarized in table F-1 of this subpart. The candidate sampler must
demonstrate performance that meets the acceptance criteria for each
applicable test to be designated as an equivalent method.
(f) Overview of various test procedures for Class II samplers--(1)
Full wind tunnel test. This test procedure is designed to ensure that
the candidate sampler's effectiveness (aspiration of an ambient aerosol
and penetration of the sub 2.5-micron fraction to its sample filter)
will be comparable to that of a reference method sampler. The candidate
sampler is challenged at wind speeds of 2 and 24 km/hr with monodisperse
aerosols of the size specified in table F-2 of this subpart. The
experimental test results are then integrated with three idealized
ambient distributions (typical, fine, and coarse) to yield the expected
mass concentration measurement for each. The acceptance criteria are
based on the results of this numerical analysis and the particle
diameter for which the sampler effectiveness is 50 percent.
(2) Wind tunnel inlet aspiration test. The wind tunnel inlet
aspiration test directly compares the inlet of the candidate sampler to
the inlet of a reference method sampler with the single-sized, liquid,
monodisperse challenge aerosol specified in table F-2 of this subpart at
wind speeds of 2 km/hr and 24 km/hr. The acceptance criteria, presented
in table F-1 of this subpart, is based on the relative aspiration
between the candidate inlet and the reference method inlet.
(3) Static fractionator test. The static fractionator test
determines the effectiveness of the candidate sampler's 2.5-micron
fractionator under static conditions for aerosols of the size specified
in table F-2 of this subpart. The numerical analysis procedures and
acceptance criteria are identical to those in the full wind tunnel test.
(4) Loading test. The loading test is conducted to ensure that the
performance of a candidate sampler is not significantly affected by the
amount of
[[Page 82]]
particulate deposited on its interior surfaces between periodic
cleanings. The candidate sampler is artificially loaded by sampling a
test environment containing aerosolized, standard test dust. The
duration of the loading phase is dependent on both the time between
cleaning as specified by the candidate method and the aerosol mass
concentration in the test environment. After loading, the candidate's
performance must then be evaluated by Sec. 53.62 (full wind tunnel
evaluation), Sec. 53.64 (wind tunnel inlet aspiration test), or
Sec. 53.64 (static fractionator test). If the results of the appropriate
test meet the criteria presented in table F-1 of this subpart, then the
candidate sampler passes the loading test under the condition that it be
cleaned at least as often as the cleaning frequency proposed by the
candidate method and that has been demonstrated to be acceptable by this
test.
(5) Volatility test. The volatility test challenges the candidate
sampler with a polydisperse, semi-volatile liquid aerosol. This aerosol
is simultaneously sampled by the candidate method sampler and a
reference method sampler for a specified time period. Clean air is then
passed through the samplers during a blow-off time period. Residual mass
is then calculated as the weight of the filter after the blow-off phase
is subtracted from the initial weight of the filter. Acceptance criteria
are based on a comparison of the residual mass measured by the candidate
sampler (corrected for flow rate variations from that of the reference
method) to the residual mass measured by the reference method sampler
for several specified clean air sampling time periods.
(g) Test data. All test data and other documentation obtained from
or pertinent to these tests shall be identified, dated, signed by the
analyst performing the test, and submitted to EPA as part of the
equivalent method application. Schematic drawings of each particle
delivery system and other information showing complete procedural
details of the test atmosphere generation, verification, and delivery
techniques for each test performed shall be submitted to EPA. All
pertinent calculations shall be clearly presented. In addition,
manufacturers are required to submit as part of the application, a
Designation Testing Checklist (Figure F-1 of this subpart) which has
been completed and signed by an ISO-certified auditor.
Sec. 53.61 Test conditions for PM2.5 reference method equivalency.
(a) Sampler surface preparation. Internal surfaces of the candidate
sampler shall be cleaned and dried prior to performing any Class II
sampler test in this subpart. The internal collection surfaces of the
sampler shall then be prepared in strict accordance with the operating
instructions specified in the sampler's operating manual referred to in
section 7.4.18 of 40 CFR part 50, appendix L.
(b) Sampler setup. Set up and start up of all test samplers shall be
in strict accordance with the operating instructions specified in the
manual referred to in section 7.4.18 of 40 CFR part 50, appendix L,
unless otherwise specified within this subpart.
(c) Sampler adjustments. Once the test sampler or samplers have been
set up and the performance tests started, manual adjustment shall be
permitted only between test points for all applicable tests. Manual
adjustments and any periodic maintenance shall be limited to only those
procedures prescribed in the manual referred to in section 7.4.18 of 40
CFR part 50, appendix L. The submitted records shall clearly indicate
when any manual adjustment or periodic maintenance was made and shall
describe the operations performed.
(d) Sampler malfunctions. If a test sampler malfunctions during any
of the applicable tests, that test run shall be repeated. A detailed
explanation of all malfunctions and the remedial actions taken shall be
submitted as part of the equivalent method application.
(e) Particle concentration measurements. All measurements of
particle concentration must be made such that the relative error in
measurement is less than 5.0 percent. Relative error is defined as (s x
100 percent)/(X), where s is the sample standard deviation of the
particle concentration detector, X is the measured concentration, and
the units of s and X are identical.
[[Page 83]]
(f) Operation of test measurement equipment. All test measurement
equipment shall be set up, calibrated, and maintained by qualified
personnel according to the manufacturer's instructions. All appropriate
calibration information and manuals for this equipment shall be kept on
file.
(g) Vibrating orifice aerosol generator conventions. This section
prescribes conventions regarding the use of the vibrating orifice
aerosol generator (VOAG) for the size-selective performance tests
outlined in Secs. 53.62, 53.63, 53.64, and 53.65.
(1) Particle aerodynamic diameter. The VOAG produces near-
monodisperse droplets through the controlled breakup of a liquid jet.
When the liquid solution consists of a non-volatile solute dissolved in
a volatile solvent, the droplets dry to form particles of near-
monodisperse size.
(i) The physical diameter of a generated spherical particle can be
calculated from the operating parameters of the VOAG as:
Equation 1
[GRAPHIC] [TIFF OMITTED] TR18JY97.094
where:
Dp = particle physical diameter, [mu]m;
Q = liquid volumetric flow rate, [mu]m3/sec;
Cvol = volume concentration (particle volume produced per
drop volume), dimensionless; and
f = frequency of applied vibrational signal, 1/sec.
(ii) A given particle's aerodynamic behavior is a function of its
physical particle size, particle shape, and density. Aerodynamic
diameter is defined as the diameter of a unit density ([rho]o
= 1g/cm3) sphere having the same settling velocity as the
particle under consideration. For converting a spherical particle of
known density to aerodynamic diameter, the governing relationship is:
Equation 2
[GRAPHIC] [TIFF OMITTED] TR18JY97.095
where:
Dae = particle aerodynamic diameter, [mu]m;
[rho]p = particle density, g/cm3;
[rho]o = aerodynamic particle density = 1 g/cm3;
CDp = Cunningham's slip correction factor for physical
particle diameter, dimensionless; and
CDae = Cunningham's slip correction factor for aerodynamic
particle diameter, dimensionless.
(iii) At room temperature and standard pressure, the Cunningham's
slip correction factor is solely a function of particle diameter:
Equation 3
[GRAPHIC] [TIFF OMITTED] TR18JY97.096
or
Equation 4
[GRAPHIC] [TIFF OMITTED] TR18JY97.097
(iv) Since the slip correction factor is itself a function of
particle diameter, the aerodynamic diameter in equation 2 of paragraph
(g)(1)(ii) of this section cannot be solved directly but must be
determined by iteration.
(2) Solid particle generation. (i) Solid particle tests performed in
this subpart shall be conducted using particles composed of ammonium
fluorescein. For use in the VOAG, liquid solutions of known volumetric
concentration can be prepared by diluting fluorescein powder
(C20H12O5, FW = 332.31, CAS 2321-07-5)
with aqueous ammonia. Guidelines for preparation of fluorescein
solutions of the desired volume concentration (Cvol) are
presented by Vanderpool and Rubow (1988) (Reference 2 in appendix A of
this subpart). For purposes of converting particle
[[Page 84]]
physical diameter to aerodynamic diameter, an ammonium fluorescein
density of 1.35 g/cm3 shall be used.
(ii) Mass deposits of ammonium fluorescein shall be extracted and
analyzed using solutions of 0.01 N ammonium hydroxide.
(3) Liquid particle generation. (i) Tests prescribed in Sec. 53.63
for inlet aspiration require the use of liquid particle tests composed
of oleic acid tagged with uranine to enable subsequent fluorometric
quantitation of collected aerosol mass deposits. Oleic acid
(C18H34O2, FW = 282.47, CAS 112-80-1)
has a density of 0.8935 g/cm3. Because the viscosity of oleic
acid is relatively high, significant errors can occur when dispensing
oleic acid using volumetric pipettes. For this reason, it is recommended
that oleic acid solutions be prepared by quantifying dispensed oleic
acid gravimetrically. The volume of oleic acid dispensed can then be
calculated simply by dividing the dispensed mass by the oleic acid
density.
(ii) Oleic acid solutions tagged with uranine shall be prepared as
follows. A known mass of oleic acid shall first be diluted using
absolute ethanol. The desired mass of the uranine tag should then be
diluted in a separate container using absolute ethanol. Uranine
(C20H10O5Na2, FW = 376.3,
CAS 518-47-8) is the disodium salt of fluorescein and has a density of
1.53 g/cm3. In preparing uranine tagged oleic acid particles,
the uranine content shall not exceed 20 percent on a mass basis. Once
both oleic acid and uranine solutions are properly prepared, they can
then be combined and diluted to final volume using absolute ethanol.
(iii) Calculation of the physical diameter of the particles produced
by the VOAG requires knowledge of the liquid solution's volume
concentration (Cvol). Because uranine is essentially
insoluble in oleic acid, the total particle volume is the sum of the
oleic acid volume and the uranine volume. The volume concentration of
the liquid solution shall be calculated as:
Equation 5
[GRAPHIC] [TIFF OMITTED] TR18JY97.098
where:
Vu = uranine volume, ml;
Voleic = oleic acid volume, ml;
Vsol = total solution volume, ml;
Mu = uranine mass, g;
[rho]u = uranine density, g/cm3;
Moleic = oleic acid mass, g; and
[rho]oleic = oleic acid density, g/cm3.
(iv) For purposes of converting the particles' physical diameter to
aerodynamic diameter, the density of the generated particles shall be
calculated as:
Equation 6
[GRAPHIC] [TIFF OMITTED] TR18JY97.099
(v) Mass deposits of oleic acid shall be extracted and analyzed
using solutions of 0.01 N sodium hydroxide.

Sec. 53.62 Test procedure: Full wind tunnel test.
(a) Overview. The full wind tunnel test evaluates the effectiveness
of the candidate sampler at 2 km/hr and 24 km/hr for aerosols of the
size specified in table F-2 of this subpart (under the heading, ``Full
Wind Tunnel Test''). For each wind speed, a smooth curve is fit to the
effectiveness data and corrected for the presence of multiplets in the
wind tunnel calibration aerosol. The cutpoint diameter (Dp50)
at each wind speed is then determined from the corrected effectiveness
curves. The two resultant penetration curves are then each numerically
integrated with three idealized ambient particle size distributions to
provide six estimates of measured mass concentration. Critical
parameters for these idealized distributions are presented in table F-3
of this subpart.
(b) Technical definitions. Effectiveness is the ratio (expressed as
a percentage) of the mass concentration of particles of a specific size
reaching the sampler filter or filters to the mass concentration of
particles of the same size approaching the sampler.
(c) Facilities and equipment required--(1) Wind tunnel. The particle
delivery system shall consist of a blower system
[[Page 85]]
and a wind tunnel having a test section of sufficiently large cross-
sectional area such that the test sampler, or portion thereof, as
installed in the test section for testing, blocks no more than 15
percent of the test section area. The wind tunnel blower system must be
capable of maintaining uniform wind speeds at the 2 km/hr and 24 km/hr
in the test section.
(2) Aerosol generation system. A vibrating orifice aerosol generator
shall be used to produce monodisperse solid particles of ammonium
fluorescein with equivalent aerodynamic diameters as specified in table
F-2 of this subpart. The geometric standard deviation for each particle
size generated shall not exceed 1.1 (for primary particles) and the
proportion of multiplets (doublets and triplets) in all test particle
atmosphere shall not exceed 10 percent of the particle population. The
aerodynamic particle diameter, as established by the operating
parameters of the vibrating orifice aerosol generator, shall be within
the tolerance specified in table F-2 of this subpart.
(3) Particle size verification equipment. The size of the test
particles shall be verified during this test by use of a suitable
instrument (e.g., scanning electron microscope, optical particle sizer,
time-of-flight apparatus). The instrument must be capable of measuring
solid and liquid test particles with a size resolution of 0.1 [mu]m or
less. The accuracy of the particle size verification technique shall be
0.15 [mu]m or better.
(4) Wind speed measurement. The wind speed in the wind tunnel shall
be determined during the tests using an appropriate technique capable of
a precision of 2 percent and an accuracy of 5 percent or better (e.g.,
hot-wire anemometry). For the wind speeds specified in table F-2 of this
subpart, the wind speed shall be measured at a minimum of 12 test points
in a cross-sectional area of the test section of the wind tunnel. The
mean wind speed in the test section must be within 10
percent of the value specified in table F-2 of this subpart, and the
variation at any test point in the test section may not exceed 10
percent of the measured mean.
(5) Aerosol rake. The cross-sectional uniformity of the particle
concentration in the sampling zone of the test section shall be
established during the tests using an array of isokinetic samplers,
referred to as a rake. Not less than five evenly spaced isokinetic
samplers shall be used to determine the particle concentration spatial
uniformity in the sampling zone. The sampling zone shall be a
rectangular area having a horizontal dimension not less than 1.2 times
the width of the test sampler at its inlet opening and a vertical
dimension not less than 25 centimeters.
(6) Total aerosol isokinetic sampler. After cross-sectional
uniformity has been confirmed, a single isokinetic sampler may be used
in place of the array of isokinetic samplers for the determination of
particle mass concentration used in the calculation of sampling
effectiveness of the test sampler in paragraph (d)(5) of this section.
In this case, the array of isokinetic samplers must be used to
demonstrate particle concentration uniformity prior to the replicate
measurements of sampling effectiveness.
(7) Fluorometer. A fluorometer used for quantifying extracted
aerosol mass deposits shall be set up, maintained, and calibrated
according to the manufacturer's instructions. A series of calibration
standards shall be prepared to encompass the minimum and maximum
concentrations measured during size-selective tests. Prior to each
calibration and measurement, the fluorometer shall be zeroed using an
aliquot of the same solvent used for extracting aerosol mass deposits.

generator or changes in the particle delivery system are necessary to
achieve uniformity, steps 1 through 5 must be repeated. When an
acceptable aerosol spatial uniformity is achieved, remove the array of
isokinetic samplers from the wind tunnel.

provided that neither the geometry of the sampler nor the length of any
connecting tube or pipe is altered. Collect particles for a time period

particle mass concentration, replace Ciso(i) with
Ciso.

effectiveness. (i) Repeat steps in paragraphs (d)(5) through (d)(7) of
this section, as appropriate, to obtain a minimum of three valid
replicate measurements of sampling effectiveness.

sizes specified in table F-2 of this subpart.
(10) Repeat steps in paragraphs (d)(1) through (d)(9) of this
section until tests have been successfully conducted for both wind
speeds of 2 km/hr and 24 km/hr.
(e) Calculations--(1) Graphical treatment of effectiveness data. For
each wind speed given in table F-2 of this subpart, plot the particle
average sampling effectiveness of the candidate sampler as a function of
aerodynamic particle diameter (Dae) on semi-logarithmic graph
paper where the aerodynamic particle diameter is the particle size
established by the parameters of the VOAG in conjunction with the known
particle density. Construct a best-fit, smooth curve through the data by
extrapolating the sampling effectiveness curve through 100 percent at an
aerodynamic particle size of 0.5 [mu]m and 0 percent at an aerodynamic
particle size of 10 [mu]m. Correction for the presence of multiplets
shall be performed using the techniques presented by Marple, et al
(1987). This multiplet-corrected effectiveness curve shall be used for

(i) Determine the value of corrected effectiveness using the best-
fit, multiplet-corrected curve at each of the particle sizes specified

Sec. 53.63 Test procedure: Wind tunnel inlet aspiration test.
(a) Overview. This test applies to a candidate sampler which differs
from the reference method sampler only with respect to the design of the
inlet. The purpose of this test is to ensure that the aspiration of a
Class II candidate sampler is such that it representatively extracts an
ambient aerosol at elevated wind speeds. This wind tunnel test uses a
single-sized, liquid aerosol in conjunction with wind speeds of 2 km/hr
and 24 km/hr. The test atmosphere concentration is alternately measured
with the candidate sampler and a reference method device, both of which
are operated without the 2.5-micron fractionation device installed. The
test conditions are summarized in table F-2 of this subpart (under the
heading of ``wind tunnel inlet aspiration test''). The candidate sampler
must meet or exceed the acceptance criteria given in table F-1 of this
subpart.

(expressed as a percentage) of the aerosol mass concentration measured
by the candidate sampler to that measured by a reference method sampler.

(Sec. 53.62(c)).
(d) Setup. The candidate and reference method samplers shall be
operated with the PM2.5 fractionation device removed from the
flow path throughout this entire test procedure. Modifications to
accommodate this requirement shall be limited to removal of the
fractionator and insertion of the filter holder directly into the
downtube of the inlet.
(e) Test procedure--(1) Establish the wind tunnel test atmosphere.
Follow the procedures in Sec. 53.62(d)(1) through (d)(4) to establish a

this subpart.
(2) Measure the aerosol concentration with the reference sampler.
(i) Install the reference sampler (or portion thereof) in the wind

that neither the geometry of the sampler nor the length of any
connecting tube or pipe is altered. Collect particles for a time period
such that the relative error of the measured concentration is less than
5.0 percent.

sampler using a calibrated fluorometer. Calculate and record the mass
concentration as:

Mcand = mass of material collected with the candidate
sampler;
[[Page 90]]

(iii) Remove the candidate sampler from the wind tunnel.
(4) Repeat steps in paragraphs (d) (2) and (d)(3) of this section.
Alternately measure the tunnel concentration with the reference sampler
and the candidate sampler until four reference sampler and three
candidate sampler measurements of the wind tunnel concentration are
obtained.

candidate sampler run as:

(B) If the value of CVA exceeds 10 percent, the entire
test procedure must be repeated.
(f) Evaluation of test results. The candidate method passes the
inlet aspiration test if all values of A meet the acceptance criteria
specified in table F-1 of this subpart.
Sec. 53.64 Test procedure: Static fractionator test.
(a) Overview. This test applies only to those candidate methods in
which the sole deviation from the reference method is in the design of
the 2.5-micron fractionation device. The purpose of this test is to
ensure that the fractionation characteristics of the candidate
fractionator are acceptably similar to that of the reference method
sampler. It is recognized that various methodologies exist for
quantifying fractionator effectiveness. The following commonly-employed
techniques are provided for purposes of guidance. Other methodologies
for determining sampler effectiveness may be used contingent upon prior
approval by the Agency.
(1) Wash-off method. Effectiveness is determined by measuring the
aerosol mass deposited on the candidate sampler's after filter versus
the aerosol mass deposited in the fractionator. The material deposited
in the fractionator is recovered by washing its internal surfaces. For
these wash-off tests, a fluorometer must be used to quantitate the
aerosol concentration. Note that if this technique is chosen, the
candidate must be reloaded with coarse aerosol prior to each test point
when reevaluating the curve as specified in the loading test.
(2) Static chamber method. Effectiveness is determined by measuring
the aerosol mass concentration sampled by the candidate sampler's after
filter versus that which exists in a static chamber. A calibrated
fluorometer shall be used to quantify the collected aerosol deposits.
The aerosol concentration is calculated as the measured aerosol mass
divided by the sampled air volume.
(3) Divided flow method. Effectiveness is determined by comparing
the aerosol concentration upstream of the candidate sampler's
fractionator versus that concentration which exists downstream of the
candidate fractionator. These tests may utilize either
[[Page 91]]
fluorometry or a real-time aerosol measuring device to determine the
aerosol concentration.
(b) Technical definition. Effectiveness under static conditions is
the ratio (expressed as a percentage) of the mass concentration of
particles of a given size reaching the sampler filter to the mass
concentration of particles of the same size existing in the test
atmosphere.
(c) Facilities and equipment required--(1) Aerosol generation.
Methods for generating aerosols shall be identical to those prescribed
in Sec. 53.62(c)(2).
(2) Particle delivery system. Acceptable apparatus for delivering
the generated aerosols to the candidate fractionator is dependent on the
effectiveness measurement methodology and shall be defined as follows:
(i) Wash-off test apparatus. The aerosol may be delivered to the
candidate fractionator through direct piping (with or without an in-line
mixing chamber). Validation particle size and quality shall be conducted
at a point directly upstream of the fractionator.
(ii) Static chamber test apparatus. The aerosol shall be introduced
into a chamber and sufficiently mixed such that the aerosol
concentration within the chamber is spatially uniform. The chamber must
be of sufficient size to house at least four total filter samplers in
addition to the inlet of the candidate method size fractionator.
Validation of particle size and quality shall be conducted on
representative aerosol samples extracted from the chamber.
(iii) Divided flow test apparatus. The apparatus shall allow the
aerosol concentration to be measured upstream and downstream of the
fractionator. The aerosol shall be delivered to a manifold with two
symmetrical branching legs. One of the legs, referred to as the bypass
leg, shall allow the challenge aerosol to pass unfractionated to the
detector. The other leg shall accommodate the fractionation device.
(3) Particle concentration measurement--(i) Fluorometry. Refer to
Sec. 53.62(c)(7).
(ii) Number concentration measurement. A number counting particle
sizer may be used in conjunction with the divided flow test apparatus in
lieu of fluorometric measurement. This device must have a minimum range
of 1 to 10 [mu]m, a resolution of 0.1 [mu]m, and an accuracy of 0.15
[mu]m such that primary particles may be distinguished from multiplets
for all test aerosols. The measurement of number concentration shall be
accomplished by integrating the primary particle peak.
(d) Setup--(1) Remove the inlet and downtube from the candidate
fractionator. All tests procedures shall be conducted with the inlet and
downtube removed from the candidate sampler.
(2) Surface treatment of the fractionator. Rinsing aluminum surfaces
with alkaline solutions has been found to adversely affect subsequent
fluorometric quantitation of aerosol mass deposits. If wash-off tests
are to be used for quantifying aerosol penetration, internal surfaces of
the fractionator must first be plated with electroless nickel.
Specifications for this plating are specified in Society of Automotive
Engineers Aerospace Material Specification (SAE AMS) 2404C, Electroless
Nickel Plating (Reference 3 in appendix A of subpart F).
(e) Test procedure: Wash-off method--(1) Clean the candidate
sampler. Note: The procedures in this step may be omitted if this test
is being used to evaluate the fractionator after being loaded as
specified in Sec. 53.65.
(i) Clean and dry the internal surfaces of the candidate sampler.

Sec. 53.65 Test procedure: Loading test.
(a) Overview. (1) The loading tests are designed to quantify any
appreciable changes in a candidate method sampler's performance as a
function of coarse aerosol collection. The candidate sampler is exposed
to a mass of coarse aerosol equivalent to sampling a mass concentration
of 150 [mu]g/m3 over the time period that the manufacturer
has specified between periodic cleaning. After loading, the candidate
sampler is then evaluated by performing the test in Sec. 53.62 (full
wind tunnel test), Sec. 53.63 (wind tunnel inlet aspiration test), or
Sec. 53.64 (static fractionator test). If the acceptance criteria are
met for this evaluation test, then the candidate sampler is approved for
multi-day sampling with the periodic maintenance schedule as specified
by the candidate method. For example, if the candidate sampler passes
the reevaluation tests following loading with an aerosol mass equivalent
to sampling a 150 [mu]g/m3 aerosol continuously for 7 days,
then the sampler is approved for 7 day field operation before cleaning
is required.
(2) [Reserved]
(b) Technical definition. Effectiveness after loading is the ratio
(expressed as a percentage) of the mass concentration of particles of a
given size reaching the sampler filter to the mass concentration of
particles of the same size approaching the sampler.
(c) Facilities and equipment required--(1) Particle delivery system.
The particle delivery system shall consist of a static chamber or a low
velocity wind tunnel having a sufficiently large cross-sectional area
such that the test sampler, or portion thereof, may be installed in the
test section. At a minimum, the system must have a sufficiently large
cross section to house the candidate sampler inlet as well as a
collocated isokinetic nozzle for measuring total aerosol concentration.
The mean velocity in the test section of the static chamber or wind
tunnel shall not exceed 2 km/hr.
(2) Aerosol generation equipment. For purposes of these tests, the
test aerosol shall be produced from commercially available, bulk Arizona
road dust. To provide direct interlaboratory comparability of sampler
loading characteristics, the bulk dust is specified as 0-10 [mu]m ATD
available from Powder Technology Incorporated (Burnsville, MN). A
fluidized bed aerosol generator, Wright dust feeder, or sonic nozzle
shall be used to efficiently deagglomerate the bulk test dust and
transform it into an aerosol cloud. Other dust generators may be used
contingent upon prior approval by the Agency.
(3) Isokinetic sampler. Mean aerosol concentration within the static
chamber or wind tunnel shall be established using a single isokinetic
sampler containing a preweighed high-efficiency total filter.
(4) Analytic balance. An analytical balance shall be used to
determine the weight of the total filter in the isokinetic sampler. The
precision and accuracy of this device shall be such that the relative
measurement error is less than 5.0 percent for the difference between
the initial and final weight of the total filter. The identical analytic
balance shall be used to perform both initial and final weighing of the
total filter.
[[Page 97]]
(d) Test procedure. (1) Calculate and record the target time
weighted concentration of Arizona road dust which is equivalent to
exposing the sampler to an environment of 150 [mu]g/m3 over
the time between cleaning specified by the candidate sampler's
operations manual as:
Equation 40
[GRAPHIC] [TIFF OMITTED] TR18JY97.133
where:
t = the number of hours specified by the candidate method prior to
periodic cleaning.
(2) Clean the candidate sampler. (i) Clean and dry the internal
surfaces of the candidate sampler.
(ii) Prepare the internal surfaces in strict accordance with the
operating manual referred to in section 7.4.18 of 40 CFR part 50,
appendix L.
(3) Determine the preweight of the filter that shall be used in the
isokinetic sampler. Record this value as InitWt.
(4) Install the candidate sampler's inlet and the isokinetic sampler
within the test chamber or wind tunnel.
(5) Generate a dust cloud. (i) Generate a dust cloud composed of
Arizona test dust.
(ii) Introduce the dust cloud into the chamber.
(iii) Allow sufficient time for the particle concentration to become
steady within the chamber.
(6) Sample aerosol with a total filter and the candidate sampler.
(i) Sample the aerosol for a time sufficient to produce an equivalent
TWC equal to that of the target TWC 15 percent.
(ii) Record the sampling time as t.
(7) Determine the time weighted concentration. (i) Determine the
postweight of the isokinetic sampler's total filter.
(ii) Record this value as FinalWt.
(iii) Calculate and record the TWC as:
Equation 41
[GRAPHIC] [TIFF OMITTED] TR18JY97.134
where:
Q = the flow rate of the candidate method.
(iv) If the value of TWC deviates from the target TWC 15
percent, then the loaded mass is unacceptable and the entire test
procedure must be repeated.
(8) Determine the candidate sampler's effectiveness after loading.
The candidate sampler's effectiveness as a function of particle
aerodynamic diameter must then be evaluated by performing the test in
Sec. 53.62 (full wind tunnel test). A sampler which fits the category of
inlet deviation in Sec. 53.60(e)(1) may opt to perform the test in
Sec. 53.63 (inlet aspiration test) in lieu of the full wind tunnel test.
A sampler which fits the category of fractionator deviation in
Sec. 53.60(e)(2) may opt to perform the test in Sec. 53.64 (static
fractionator test) in lieu of the full wind tunnel test.
(e) Test results. If the candidate sampler meets the acceptance
criteria for the evaluation test performed in paragraph (d)(8) of this
section, then the candidate sampler passes this test with the
stipulation that the sampling train be cleaned as directed by and as
frequently as that specified by the candidate sampler's operations
manual.
Sec. 53.66 Test procedure: Volatility test.
(a) Overview. This test is designed to ensure that the candidate
method's losses due to volatility when sampling semi-volatile ambient
aerosol will be comparable to that of a federal reference method
sampler. This is accomplished by challenging the candidate sampler with
a polydisperse, semi-volatile liquid aerosol in three distinct phases.
During phase A of this test, the aerosol is elevated to a steady-state,
test-specified mass concentration and the sample filters are conditioned
and preweighed. In phase B, the challenge aerosol is simultaneously
sampled by the candidate method sampler and a reference method sampler
onto the preweighed filters for a specified time period. In phase C (the
blow-off phase), aerosol and aerosol-vapor free air is sampled by the
samplers for an additional time period to partially volatilize the
aerosol on the filters. The candidate sampler passes the volatility test
if the acceptance criteria presented in table F-1 of this subpart are
met or exceeded.
(b) Technical definitions. (1) Residual mass (RM) is defined as the
weight of
[[Page 98]]
the filter after the blow-off phase subtracted from the initial weight
of the filter.
(2) Corrected residual mass (CRM) is defined as the residual mass of
the filter from the candidate sampler multiplied by the ratio of the
reference method flow rate to the candidate method flow rate.
(c) Facilities and equipment required--(1) Environmental chamber.
Because the nature of a volatile aerosol is greatly dependent upon
environmental conditions, all phases of this test shall be conducted at
a temperature of 22.0 0.5 deg.C and a relative humidity of
40 3 percent. For this reason, it is strongly advised that
all weighing and experimental apparatus be housed in an environmental
chamber capable of this level of control.
(2) Aerosol generator. The aerosol generator shall be a pressure
nebulizer operated at 20 to 30 psig (140 to 207 kPa) to produce a
polydisperse, semi-voltile aerosol with a mass median diameter larger
than 1 [mu]m and smaller than 2.5 [mu]m. The nebulized liquid shall be
A.C.S. reagent grade glycerol (C3H8O, FW = 92.09,
CAS 56-81-5) of 99.5 percent minimum purity. For the purpose of this
test the accepted mass median diameter is predicated on the stable
aerosol inside the internal chamber and not on the aerosol emerging from
the nebulizer nozzle. Aerosol monitoring and its stability are described
in (c)(3) and (c)(4) of this section.
(3) Aerosol monitoring equipment. The evaporation and condensation
dynamics of a volatile aerosol is greatly dependent upon the vapor
pressure of the volatile component in the carrier gas. The size of an
aerosol becomes fixed only when an equilibrium is established between
the aerosol and the surrounding vapor; therefore, aerosol size
measurement shall be used as a surrogate measure of this equilibrium. A
suitable instrument with a range of 0.3 to 10 [mu]m, an accuracy of 0.5
[mu]m, and a resolution of 0.2 [mu]m (e.g., an optical particle sizer,
or a time-of-flight instrument) shall be used for this purpose. The
parameter monitored for stability shall be the mass median instrument
measured diameter (i.e. optical diameter if an optical particle counter
is used). A stable aerosol shall be defined as an aerosol with a mass
median diameter that has changed less than 0.25 [mu]m over a 4 hour time
period.
(4) Internal chamber. The time required to achieve a stable aerosol
depends upon the time during which the aerosol is resident with the
surrounding air. This is a function of the internal volume of the
aerosol transport system and may be facilitated by recirculating the
challenge aerosol. A chamber with a volume of 0.5 m3 and a
recirculating loop (airflow of approximately 500 cfm) is recommended for
this purpose. In addition, a baffle is recommended to dissipate the jet
of air that the recirculating loop can create. Furthermore, a HEPA
filtered hole in the wall of the chamber is suggested to allow makeup
air to enter the chamber or excess air to exit the chamber to maintain a
system flow balance. The concentration inside the chamber shall be
maintained at 1 mg/m3 20 percent to obtain
consistent and significant filter loading.
(5) Aerosol sampling manifold. A manifold shall be used to extract
the aerosol from the area in which it is equilibrated and transport it
to the candidate method sampler, the reference method sampler, and the
aerosol monitor. The losses in each leg of the manifold shall be
equivalent such that the three devices will be exposed to an identical
aerosol.
(6) Chamber air temperature recorders. Minimum range 15-25 deg.C,
certified accuracy to within 0.2 deg.C, resolution of 0.1 deg.C.
Measurement shall be made at the intake to the sampling manifold and
adjacent to the weighing location.
(7) Chamber air relative humidity recorders. Minimum range 30 - 50
percent, certified accuracy to within 1 percent, resolution of 0.5
percent. Measurement shall be made at the intake to the sampling
manifold and adjacent to the weighing location.
(8) Clean air generation system. A source of aerosol and aerosol-
vapor free air is required for phase C of this test. This clean air
shall be produced by filtering air through an absolute (HEPA) filter.
(9) Balance. Minimum range 0 - 200 mg, certified accuracy to within
10 [mu]g, resolution of 1 [mu]g.
[[Page 99]]
(d) Additional filter handling conditions. (1) Filter handling.
Careful handling of the filter during sampling, conditioning, and
weighing is necessary to avoid errors due to damaged filters or loss of
collected particles from the filters. All filters must be weighed
immediately after phase A dynamic conditioning and phase C.
(2) Dynamic conditioning of filters. Total dynamic conditioning is
required prior to the initial weight determined in phase A. Dynamic
conditioning refers to pulling clean air from the clean air generation
system through the filters. Total dynamic conditioning can be
established by sequential filter weighing every 30 minutes following
repetitive dynamic conditioning. The filters are considered sufficiently
conditioned if the sequential weights are repeatable to 3
[mu]g.
(3) Static charge. The following procedure is suggested for
minimizing charge effects. Place six or more Polonium static control
devices (PSCD) inside the microbalance weighing chamber, (MWC). Two of
them must be placed horizontally on the floor of the MWC and the
remainder placed vertically on the back wall of the MWC. Taping two
PSCD's together or using double-sided tape will help to keep them from
falling. Place the filter that is to be weighed on the horizontal PSCDs
facing aerosol coated surface up. Close the MWC and wait 1 minute. Open
the MWC and place the filter on the balance dish. Wait 1 minute. If the
charges have been neutralized the weight will stabilize within 30-60
seconds. Repeat the procedure of neutralizing charges and weighing as
prescribed above several times (typically 2-4 times) until consecutive
weights will differ by no more than 3 micrograms. Record the last
measured weight and use this value for all subsequent calculations.
(e) Test procedure--(1) Phase A - Preliminary steps. (i) Generate a
polydisperse glycerol test aerosol.
(ii) Introduce the aerosol into the transport system.
(iii) Monitor the aerosol size and concentration until stability and
level have been achieved.
(iv) Condition the candidate method sampler and reference method
sampler filters until total dynamic conditioning is achieved as
specified in paragraph (d)(2) of this section.
(v) Record the dynamically conditioned weight as InitWtc
and InitWtr where c is the candidate method sampler and r is
the reference method sampler.
(2) Phase B - Aerosol loading. (i) Install the dynamically
conditioned filters into the appropriate samplers.
(ii) Attach the samplers to the manifold.
(iii) Operate the candidate and the reference samplers such that
they simultaneously sample the test aerosol for 30 minutes.
(3) Phase C - Blow-off. (i) Alter the intake of the samplers to
sample air from the clean air generation system.
(ii) Sample clean air for one of the required blow-off time
durations (1, 2, 3, and 4 hours).
(iii) Remove the filters from the samplers.
(iv) Weigh the filters immediately and record this weight,
FinalWtc and FinalWtr, where c is the candidate
method sampler and r is the reference method sampler.
(v) Calculate the residual mass for the reference method sampler:
Equation 41a
[GRAPHIC] [TIFF OMITTED] TR18JY97.135
where:
i = repetition number; and
j = blow-off time period.
(vi) Calculate the corrected residual mass for the candidate method
sampler as:
Equation 41b
[GRAPHIC] [TIFF OMITTED] TR18JY97.136
where:
i = repetition number;
j = blow-off time period;
Qc = candidate method sampler flow rate, and
Qr = reference method sampler flow rate.
(4) Repeat steps in paragraph (e)(1) through (e)(3) of this section
until three repetitions have been completed for each of the required
blow-off time durations (1, 2, 3, and 4 hours).
[[Page 100]]
(f) Calculations and analysis. (1) Perform a linear regression with
the candidate method CRM as the dependent variable and the reference
method RM as the independent variable.
(2) Determine the following regression parameters: slope, intercept,
and correlation coefficient (r).
(g) Test results. The candidate method passes the volatility test if
the regression parameters meet the acceptance criteria specified in
table F-1 of this subpart.

Incorporated by Reference Into Part 55, by State
Authority: Section 328 of the Clean Air Act (42 U.S.C. 7401, et
seq.) as amended by Public Law 101-549.
Source: 57 FR 40806, Sept. 4, 1992, unless otherwise noted.
Sec. 55.1 Statutory authority and scope.
Section 328(a)(1) of the Clean Air Act (``the Act''), requires the
Environmental Protection Agency (``EPA'') to establish requirements to
control air pollution from outer continental shelf (``OCS'') sources in
order to attain and maintain Federal and State ambient air quality
standards and to comply with the provisions of part C of title I of the
Act. This part establishes the air pollution control requirements for
OCS sources and the procedures for implementation and enforcement of the
requirements, consistent with these stated objectives of section
328(a)(1) of the Act. In implementing, enforcing and revising this rule
and in delegating authority hereunder, the Administrator will ensure
that there is a rational relationship to the attainment and maintenance
of Federal and State ambient air quality standards and the requirements
of part C of title I, and that the rule is not used for the purpose of
preventing exploration and development of the OCS.
Sec. 55.2 Definitions.
Administrator means the Administrator of the U.S. Environmental
Protection Agency.
Corresponding Onshore Area (COA) means, with respect to any existing
or proposed OCS source located within 25 miles of a State's seaward
boundary, the onshore area that is geographically
[[Page 106]]
closest to the source or another onshore area that the Administrator
designates as the COA, pursuant to Sec. 55.5 of this part.
Delegated agency means any agency that has been delegated authority
to implement and enforce requirements of this part by the Administrator,
pursuant to Sec. 55.11 of this part. It can refer to a State agency, a
local agency, or an Indian tribe, depending on the delegation status of
the program.
Existing source or existing OCS source shall have the meaning given
in the applicable requirements incorporated into Secs. 55.13 and 55.14
of this part, except that for two years following the date of
promulgation of this part the definition given in Sec. 55.3 of this part
shall apply for the purpose of determining the required date of
compliance with this part.
Exploratory source or exploratory OCS source means any OCS source
that is a temporary operation conducted for the sole purpose of
gathering information. This includes an operation conducted during the
exploratory phase to determine the characteristics of the reservoir and
formation and may involve the extraction of oil and gas.
Modification shall have the meaning given in the applicable
requirements incorporated into Secs. 55.13 and 55.14 of this part,
except that for two years following the date of promulgation of this
part the definition given in section 111(a) of the Act shall apply for
the purpose of determining the required date of compliance with this
part, as set forth in Sec. 55.3 of this part.
Nearest Onshore Area (NOA) means, with respect to any existing or
proposed OCS source, the onshore area that is geographically closest to
that source.
New source or new OCS source shall have the meaning given in the
applicable requirements of Secs. 55.13 and 55.14 of this part, except
that for two years following the date of promulgation of this part, the
definition given in Sec. 55.3 of this part shall apply for the purpose
of determining the required date of compliance with this part.
OCS source means any equipment, activity, or facility which:
(1) Emits or has the potential to emit any air pollutant;
(2) Is regulated or authorized under the Outer Continental Shelf
Lands Act (``OCSLA'') (43 U.S.C. Sec. 1331 et seq.); and
(3) Is located on the OCS or in or on waters above the OCS.
This definition shall include vessels only when they are:
(1) Permanently or temporarily attached to the seabed and erected
thereon and used for the purpose of exploring, developing or producing
resources therefrom, within the meaning of section 4(a)(1) of OCSLA (43
U.S.C. Sec. 1331 et seq.); or
(2) Physically attached to an OCS facility, in which case only the
stationary sources aspects of the vessels will be regulated.
Onshore area means a coastal area designated as an attainment,
nonattainment, or unclassifiable area by EPA in accordance with section
107 of the Act. If the boundaries of an area designated pursuant to
section 107 of the Act do not coincide with the boundaries of a single
onshore air pollution control agency, then onshore area shall mean a
coastal area defined by the jurisdictional boundaries of an air
pollution control agency.
Outer continental shelf shall have the meaning provided by section 2
of the OCSLA (43 U.S.C. Sec. 1331 et seq.).
Potential emissions means the maximum emissions of a pollutant from
an OCS source operating at its design capacity. Any physical or
operational limitation on the capacity of a source to emit a pollutant,
including air pollution control equipment and restrictions on hours of
operation or on the type or amount of material combusted, stored, or
processed, shall be treated as a limit on the design capacity of the
source if the limitation is federally enforceable. Pursuant to section
328 of the Act, emissions from vessels servicing or associated with an
OCS source shall be considered direct emissions from such a source while
at the source, and while enroute to or from the source when within 25
miles of the source, and shall be included in the ``potential to emit''
for an OCS source. This definition does not alter or affect the use of
this term for any other purposes under Secs. 55.13 or 55.14 of this
part, except that vessel emissions must be
[[Page 107]]
included in the ``potential to emit'' as used in Secs. 55.13 and 55.14
of this part.
Residual emissions means the difference in emissions from an OCS
source if it applies the control requirements(s) imposed pursuant to
Sec. 55.13 or Sec. 55,14 of this part and emissions from that source if
it applies a substitute control requirement pursuant to an exemption
granted under Sec. 55.7 of this part.
State means the State air pollution control agency that would be the
permitting authority, a local air pollution permitting agency, or
certain Indian tribes which can be the permitting authority for areas
within their jurisdiction. State may also be used in the geographic
sense to refer to a State, the NOA, or the COA.
[57 FR 40806, Sept. 4, 1992, as amended at 62 FR 46408, Sept. 2, 1997]

(10) Such other information as may be necessary to determine the
source's impact in onshore areas.
[[Page 108]]
(c) Exploratory sources and modifications to existing sources with
designated COAs shall be exempt from the requirement in paragraph
(b)(10) of this section.
(d) The scope and contents of the NOI shall in no way limit the
scope and contents of the required permit application or applicable
requirements given in this part.
Sec. 55.5 Corresponding onshore area designation.
(a) Proposed exploratory sources. The NOA shall be the COA for
exploratory sources located within 25 miles of States' seaward
boundaries. Paragraphs (b), (c), and (f) of this section are not
applicable to these sources.
(b) Requests for designation. (1) The chief executive officer of the
air pollution control agency of an area that believes it has more
stringent air pollution control requirements than the NOA for a proposed
OCS source, may submit a request to be designated as the COA to the
Administrator and at the same time shall send copies of the request to
the chief executive officer of the NOA and to the proposed source. The
request must be received by the Administrator within 60 days of the
receipt of the NOI. If no requests are received by the Administrator
within 60 days of the receipt of the NOI, the NOA will become the
designated COA without further action.
(2) No later than 90 days after the receipt of the NOI, a
demonstration must be received by the Administrator showing that:
(i) The area has more stringent requirements with respect to the
control and abatement of air pollution than the NOA;
(ii) The emissions from the source are or would be transported to
the requesting area; and
(iii) The transported emissions would affect the requesting area's
efforts to attain or maintain a Federal or State ambient air quality
standard or to comply with the requirements of part C of title I of the
Act, taking into account the effect of air pollution control
requirements that would be imposed if the NOA were designated as the
COA.
(c) Determination by the Administrator. (1) If no demonstrations are
received by the Administrator within 90 days of the receipt of the NOI,
the NOA will become the designated COA without further action.
(2) If one or more demonstrations are received, the Administrator
will issue a preliminary designation of the COA within 150 days of the
receipt of the NOI, which shall be followed by a 30 day public comment
period, in accordance with paragraph (f) of this section.
(3) The Administrator will designate the COA for a specific source
within 240 days of the receipt of the NOI.
(4) When the Administrator designates a more stringent area as the
COA with respect to a specific OCS source, the delegated agency in the
COA will exercise all delegated authority. If there is no delegated
agency in the COA, then EPA will issue the permit and implement and
enforce the requirements of this part. The Administrator may retain
authority for implementing and enforcing the requirements of this part
if the NOA and the COA are in different States.
(5) The Administrator shall designate the COA for each source only
once in the source's lifetime.
(d) Offset requirements. Offsets shall be obtained based on the
applicable requirements of the COA, as set forth in Secs. 55.13 and
55.14 of this part.
(e) Authority to designate the COA. The authority to designate the
COA for any OCS source shall not be delegated to a State or local
agency, but shall be retained by the Administrator.
(f) Administrative procedures and public participation. The
Administrator will use the following public notice and comment
procedures for processing a request for COA designation under this
section:
(1) Within 150 days from receipt of an NOI, if one or more
demonstrations are received, the Administrator shall make a preliminary
determination of the COA and shall:
(i) Make available, in at least one location in the NOA and in the
area requesting COA designation, a copy of all materials submitted by
the requester, a copy of the Administrator's preliminary determination,
and a copy or summary of other materials, if any, considered by the
Administrator in
[[Page 109]]
making the preliminary determination; and
(ii) Notify the public, by prominent advertisement in a newspaper of
general circulation in the NOA and the area requesting COA designation,
of a 30-day opportunity for written public comment on the available
information and the Administrator's preliminary COA designation.
(2) A copy of the notice required pursuant to paragraph (f)(1)(ii)
of this section shall be sent to the requester, the affected source,
each person from whom a written request of such notice has been
received, and the following officials and agencies having jurisdiction
over the COA and NOA: State and local air pollution control agencies,
the chief executive of the city and county, the Federal Land Manager of
potentially affected Class I areas, and any Indian governing body whose
lands may be affected by emissions from the OCS source.
(3) Public comments received in writing within 30 days after the
date the public notice is made available will be considered by the
Administrator in making the final decision on the request. All comments
will be made available for public inspection.
(4) The Administrator will make a final COA designation within 60

Sec. 55.6 Permit requirements.
(a) General provisions--(1) Permit applications. (i) The owner or
operator of an OCS source shall submit to the Administrator or delegated
agency all information necessary to perform any analysis or make any
determination required under this section.
(ii) Any application submitted pursuant to this part by an OCS
source shall include a description of all the requirements of this part
and a description of how the source will comply with the applicable
requirements. For identification purposes only, the application shall
include a description of those requirements that have been proposed by
EPA for incorporation into this part and that the applicant believes,
after diligent research and inquiry, apply to the source.
(2) Exemptions. (i) When an applicant submits any approval to
construct or permit to operate application to the Administrator or
delegated agency it shall include a request for exemption from
compliance with any pollution control technology requirement that the

by the permitting authority, the owner or operator of the source shall
be subject to the permitting requirements of Secs. 55.13 and 55.14 of
this part that apply subsequent to the submission of a complete permit
application. When a source receives the permit or permits required under
this part, its TPA shall expire.
(4) Until the date that a source subject to this subsection receives
the permit or permits required under this part, that source shall cease
operation if, based on projected or actual emissions, the permitting
authority determines that the source is currently or may in the future
cause or contribute to a violation of a State or Federal ambient air
quality standard or exceed any applicable increment.

into the final permit issued by the delegated agency. If no permit is
required, the Administrator's final decision on the request shall be
implemented and enforced by the delegated agency.
(d) Preliminary determination. The Administrator or delegated agency
shall issue a preliminary determination in accordance with paragraph (f)
of this section. A preliminary determination shall propose to grant or
deny the request for exemption. A preliminary determination to grant the
request shall include proposed substitute control requirements and
offsets necessary to comply with the requirements of paragraph (e) of
this section.
(e) Grant of exemption. (1) The source shall comply with a
substitute requirement(s), equal to or as close in stringency to the
original requirement as possible, as determined by the Administrator or
delegated agency.
(2) An OCS source located within 25 miles of States' seaward
boundaries shall offset residual emissions resulting from the grant of
an exemption request in accordance with the requirements of the Act and
the regulations thereunder. The source shall obtain offsets in
accordance with the applicable requirements as follows:

delegation within 6 months of the receipt of the request.
(d) If the Administrator finds that the State regulations are
adequate, the Administrator will authorize the State to implement and
enforce the OCS requirements under State law. If the Administrator finds
that only part of the State regulations are adequate, he will authorize
the State to implement and enforce only that portion of this part.
(e) Upon delegation, a State may use any authority it possesses
under State law to enforce any permit condition or any other requirement
of this part for which the agency has delegated authority under this
part. A State may use anyauthority it possesses under State law to
require monitoring and reporting and to conduct inspections.
(f) Nothing in this part shall prohibit the Administrator from
enforcing any requirement of this part.
(g) The Administrator will withdraw a delegation of any authority to
implement and enforce any or all of this part if the Administrator

Sec. 55.11(b) of this part.
(h) Sharing of information. Any information obtained or used in the
administration of a delegated program shall be made available to EPA
upon request without restriction. If the information has been submitted
to the delegated agency under a claim of confidentiality, the delegated
agency must notify the source of this obligation and submit that claim
to EPA. Any information obtained from a delegated agency accompanied by
a claim of confidentiality will be treated in accordance with the
requirements of 40 CFR part 2.
(i) Grant of exemptions. A decision by a delegated agency to grant
or deny an exemption request may be appealed to the Administrator in
accordance with Sec. 55.7 of this part.
(j) Delegated authority. The delegated agency in the COA for sources
located within 25 miles of the State's seaward boundary or the delegated
agency in the NOA for sources located beyond 25 miles of the State's
seaward boundary will exercise all delegated authority. If there is no
delegated agency in the COA for sources located within 25 miles of the
State's seaward boundary, or in the NOA for sources located beyond 25
miles of the State's seaward boundary, the EPA will issue the permit and
implement and enforce the requirements of this part. For sources located
within 25 miles of the State's seaward boundary, the Administrator may
retain the authority for implementing and enforcing the requirements of
this part if the NOA and COA are in different States.

evaluate the requirements of part 55 to determine whether they are
consistent with the current onshore requirements.
(2) If the Administrator finds that part 55 is inconsistent with the
requirements in effect in the onshore area, EPA will conduct a notice
and comment rulemaking to update part 55 accordingly.
(c) Consistency reviews triggered by receipt of an NOI. Upon receipt
of an NOI, the Administrator will initiate a consistency review of
regulations in the onshore area.
(1) If the NOI is submitted by a source for which the COA has
previously been assigned, EPA will publish a proposed consistency update
in the Federal Register no later than 60 days after the receipt of the
NOI, if an update is deemed necessary by the Administrator:
(2) If the NOI is submitted by a source requiring a COA designation,
EPA will publish a proposed consistency update in the Federal Register,
if an update is deemed necessary by the Administrator:
(i) No later than 75 days after receipt of the NOI if no adjacent

U.S.C. 7410, 7414, 7419, and 7601); sec. 406 of Pub. L. 95-95.
Source: 50 FR 6448, Feb. 15, 1985, unless otherwise noted.
Subpart A--General
Sec. 57.101 Purpose and scope.
(a) Applicability of the regulations. The regulations in subparts A
through H govern:
(1) The eligibility of smelters for a Primary Nonferrous Smelter
Order (NSO) under section 119 of the Clean Air Act;
(2) The procedures through which an NSO can be approved or issued by
EPA; and
(3) The minimum contents of each NSO required for EPA issuance or
approval under section 119. Subpart I et
[[Page 132]]
seq., will contain NSOs in effect for individual smelters.
(b) State authority to adopt more stringent requrements. Nothing in
this part shall preclude a State from imposing more stringent
requirements, as provided by section 116 of the Clean Air Act.
Sec. 57.102 Eligibility.
(a) A primary copper, lead, zinc, molybdenum, or other nonferrous
smelter is eligible for an NSO if it meets the following conditions:
(1) The smelter was in existence and operating on August 7, 1977;
(2) The smelter is subject to an approved or promulgated sulfur
dioxide (SO2) State Implementation Plan (SIP) emission
limitation which is adequate to ensure that National Ambient Air Quality
Standards (NAAQS) for SO2 are achieved without the use of any
unauthorized dispersion techniques; and
(3) The Administrator determines, based on a showing by the smelter
owner, that no means of emission limitation applicable to the smelter
which would enable it to comply with its SIP stack emission limitation
for SO2 has been adequately demonstrated to be reasonably
available (taking into account the cost of compliance, nonair quality
health and environmental impact, and energy considerations) in
accordance with Sec. 57.201(d)(1).
(b) For the purposes of these regulations:
(1) The following means of emission limitation shall be considered
adequately demonstrated for nonferrous smelters. (Taking into account
nonair quality health and environmental impact and energy
considerations, but not the cost of compliance).
(i) Retrofit control technologies.
(A) Sulfuric acid plant in conjunction with an adequately
demonstrated replacement technology or process modification;
(B) Magnesium oxide (concentration) scrubbing;
(C) Lime/limestone scrubbing; and
(D) Ammonia scrubbing.
(ii) Replacement or process modifications.
(A) Flash smelting;
(B) Oxygen enrichment;
(C) Supplemental sulfur burning in conjunction with acid plant;
(D) Electric Furnace;
(E) Noranda process;
(F) Fluid bed roaster;
(G) Continuous smelting (Mitsubishi) process; and
(H) Strong stream/weak stream gas blending.
(2) Each adequately demonstrated means of emission limitation which
would enable a smelter to comply with its SIP emission limitation for
SO2 shall be considered applicable to the smelter unless the
smelter operator demonstrates that the use of a particular system at
that smelter is technically unreasonable, for reasons specific to that
site.
(3) An applicable means of emission limitation which would enable a
smelter to comply with its SIP emission limitation for SO2
shall be considered adequately demonstrated to be reasonably available
to the smelter (taking into account the cost of compliance) if the
information submitted under Secs. 57.107(a) and 57.203(b) (plus any
necessary supplemental information) shows, according to the criteria,
procedures, and tests contained in appendix A to this part and in
accordance with Sec. 57.201(d)(1), that both of the following two tests
are met.
(i) The rate of return test. The present value of the smelter's
future net cash flow (during and after investment in constant control
technology) is more than book value of the smelter's net investment in
constant dollars.
(ii) The profit protection test. The constant control technology
expenditure reduces the present value of the smelter's forecast pretax
profits by less than 50%.
(c) When applying for an NSO, a smelter must establish, for purposes
of applying the financial eligibility tests, which adequately
demonstrated constant control technology applicable to that smelter is
the most economically feasible for use at that smelter.
[50 FR 6448, Feb. 15, 1985, as amended at 51 FR 10211, Mar. 25, 1986]
Sec. 57.103 Definitions.
(a) The Act means the Clean Air Act, as amended.
[[Page 133]]
(b) Active use refers to an SO2 constant control system
installed at a smelter before August 7, 1977 and not totally removed
from regular service by that date.
(c) Adequate SO2 emission limitation means a SIP emission
limitation which was approved or promulgated by EPA as adequate to
attain and maintain the NAAQS in the areas affected by the stack
emissions without the use of any unauthorized dispersion technique.
(d) Administrative Law Judge means an administrative law judge
appointed under 5 U.S.C. 3105 (see also 5 CFR part 930, as amended by 37
FR 16787), and is synonymous with the term ``Hearing Examiner'' as
formerly used in Title 5 of the U.S. Code.
(e) The Administrator means the Administrator of the U.S.
Environmental Protection Agency, or the Administrator's authorized
representative.
(f) Ambient air shall have the meaning given by 40 CFR 50.1(e), as
that definition appears upon promulgation of this subpart, or as
hereafter amended.
(g) Ambient air quality refers only to concentrations of sulfur
dioxide in the ambient air, unless otherwise specified.
(h) An approved measure refers to one contained in an NSO which is
in effect.
(i) Assistant Administrator for Air and Radiation means the
Assistant Administrator for Air and Radiation of the U.S. Environmental
Protection Agency.
(j) Constant controls, control technology, and continuous emission
reduction technology mean systems which limit the quantity, rate, or
concentration, excluding the use of dilution, and emissions of air
pollutants on a continuous basis.
(k) Effective date of an NSO means the effective date listed in the
Federal Register publication of EPA's issuance or approval of an NSO.
(l) EPA and the Agency means the Administrator of the U.S.
Environmental Protection Agency, or the Administrator's authorized
representative.
(m) Fugitive emissions means any air pollutants emitted to the
atmosphere other than from a stack.
(n) Issuance of an NSO means the final transmittal of the NSO
pursuant to Sec. 57.107(a) by an issuing agency (other than EPA) to EPA
for approval, or the publication of an NSO issued by EPA in the Federal
Register.
(o) Issuing agency, unless otherwise specifically indicated, means
the State or local air pollution control agency to which a smelter's
owner has applied for an NSO, or which has issued the NSO, or EPA, when
the NSO application has been made to EPA. Any showings or demonstrations
required to be made under this part to the issuing agency, when not EPA,
are subject to independent determinations by EPA.
(p) Malfunction means any unanticipated and unavoidable failure of
air pollution control equipment or process equipment or of a process to
operate in a normal or usual manner. Failures that are caused entirely
or in part by poor design, poor maintenance, careless operation, or any
other preventable upset condition or preventable equipment breakdown
shall not be considered malfunctions. A malfunction exists only for the
minimum time necessary to implement corrective measures.
(q) Maximum production capacity means either the maximum
demonstrated rate at which a smelter has produced its principal metallic
final product under the process equipment configuration and operating
procedures prevailing on or before August 7, 1977, or a rate which the
smelter is able to demonstrate by calculation is attainable with process
equipment existing on August 7, 1977. The rate may be expressed as a
concentrate feed rate to the smelter.
(r) NAAQS and National Ambient Air Quality Standards, unless
otherwise specified, refer only to the National Primary and Secondary
Ambient Air Quality Standards for sulfur dioxide.

the purposes of this part, the term supplementary control system does
not include any dispersion technique based solely on the use of a stack
the height of which exceeds good engineering practice (as determined
under regulations implementing section 123 of the Act).
(v) Unauthorized dispersion technique refers to any dispersion
technique which, under section 123 of the Act and the regulations
promulgated pursuant to that section, may not be used to reduce the
degree of emission limitation otherwise required in the applicable SIP.
(w) Unless otherwise specified in this part, all terms shall have
the same meaning given them by the Act.
[50 FR 6448, Feb. 15, 1985, as amended at 57 FR 5328, Feb. 13, 1992]
Sec. 57.104 Amendment of the NSO.
An NSO shall be amended whenever necessary for compliance with the
requirements and purposes of this part.
(a)(1) Issuance of amendment. A State or local issuing agency may
issue an amendment of any NSO it has issued. Any amendment issued by a
State or local issuing agency shall be subject to approval by EPA to the
same extent as was the original NSO. Any smelter owner may apply to the
agency which originally issued its NSO for an amendment of the NSO at
any time. Such an application shall be accompanied by whatever
documentation is required by that agency (or EPA) to support the
requested amendment.

date is unchanged. Delays longer than 3 months shall be handled
according to the provisions of Sec. 57.104(a)(1).
(ii) Changes made in accordance with this subparagraph may be
effective immediately but must be submitted to EPA within seven days.
EPA will give public notice of receipt of such changes by publication of
a Notice in the Federal Register.
(3) In any case in which the issuing agency fails to issue an
amendment necessary for compliance with the requirements and purposes of
this part, EPA may, after first giving the issuing Agency notice, issue
such amendment.
(b) Revision of SCS Manual. Operation in accordance with the revised
provisions of an SCS operational manual (see Sec. 57.402(e)) shall not
be considered a violation of an NSO while the application for approval
of those revisions as NSO amendments is pending before the issuing
agency (or EPA) for approval: Provided, that:
(1) No violations of NAAQS occur in the smelter's Designated
Liability Area during that time; and
(2) The smelter operator has not been informed by the issuing agency
or EPA that its application is not adequately documented, unless such
deficiency has been remedied promptly.
(c) Notice and opportunity for hearing. Notice and opportunity for
public hearing shall be provided before issuance of all major
amendments.
Sec. 57.105 Submittal of required plans, proposals, and reports.
(a) The failure of a smelter owner to submit any plan, report,
document or proposal as required by its NSO or by this part shall
constitute a violation of its NSO.
(b) If the Administrator determines that a nonferrous smelter is in
violation of a requirement contained in an NSO approved under these
regulations, the Administrator shall, as provided by section 119(f) of
the Act:
(1) Enforce such requirement under section 113 (a), (b), or (c) of
the Act;
(2) Revoke the order after notice and opportunity for hearing;
(3) Give notice of noncompliance and commence action under section
120 of the act; or
(4) Take any appropriate combinations of these actions.
(c) Under section 304 of the Act, any person may commence a civil
action
[[Page 135]]
against an owner or operator of a smelter which is alleged to be in
violation or any order approved under this part.
Sec. 57.106 Expiration date.
Each NSO shall state its expiration date. No NSO issued under this
regulation shall expire later than January 1, 1988.
Sec. 57.107 The State or local agency's transmittal to EPA.
(a) Content and bases of the State or local agency's NSO. Issuance
of an NSO by a State or local agency shall be completed by the issuing
agency's transmittal to the appropriate EPA Regional Office of:
(1) The text of the NSO;
(2) The application submitted by the smelter owner, except for
appendix A to this part, all correspondence between the issuing agency
and the applicant relating to the NSO, and any material submitted in
support of the application;
(3) A concise statement of the State or local agency's findings and
their bases; and
(4) All documentation or analyses prepared by or for the issuing
agency in support of the NSO.
(b) The State or local agency's enforcement plan. The transmittal
under paragraph (a) of this section shall be accompanied by a
description of the issuing agency's plans for monitoring compliance with
and enforcement of the NSO. The transmittal shall also include a
description of the resources which will be used to implement those
plans. If the enforcement plans appear inadequate, EPA may require that
the NSO be modified such that the NSO will be adequately enforced.
Sec. 57.108 Comparable existing SIP provisions.
Notwithstanding any other provision of this part, an NSO may contain
provisions to which the affected smelter is subject under the applicable
EPA-approved State Implementation Plan (SIP) for sulfur dioxide in lieu
of the corresponding provisions which would otherwise be required under
this part if the Administrator determines that those SIP provisions are
substantially equivalent to the corresponding NSO provisions which would
otherwise be required, and if the Administrator determines that the
smelter is in substantial compliance with those SIP provisions. For the
purposes of this section, provisions to which the affected smelter is
subject under the applicable EPA-approved State Implementation Plan are
those which became effective before the smelter owner applied for the
NSO.
Sec. 57.109 Maintenance of pay.
The Administrator will not approve or issue an NSO for any smelter
unless he has approved or promulgated SIP provisions which are
applicable to the smelter and which satisfy the requirements of section
110(a)(6) of the Clean Air Act.
Sec. 57.110 Reimbursement of State or local agency.
As a condition of issuing an NSO, any issuing agency may require the
smelter operator to pay a fee to the State or local agency sufficient to
defray the issuing agency's expenses in issuing and enforcing the NSO.
Sec. 57.111 Severability of provisions.
The provisions promulgated in this part and the various applications
thereof are distinct and severable. If any provision of this part or the
application thereof to any person or circumstances is held invalid, such
invalidity shall not affect other provisions, or the application of such
provisions to other persons or circumstances, which can be given effect
without the invalid provision of application.
Subpart B--The Application and the NSO Process
Sec. 57.201 Where to apply.
Any eligible smelter may apply for an NSO to the appropriate EPA
Regional Office or to the appropriate State or local air pollution
control agency.
(a) When application is made to EPA, all parts of the application
required to be submitted under this subpart shall be sent directly to
the Director, Stationary Source Compliance Division
[[Page 136]]
(EN-341), U.S. Environmental Protection Agency, 1200 Pennsylvania Ave.,
NW., Washington, DC 20460, Attention: Confidential Information Unit. In
addition, the smelter owner shall send a copy of the application, except
that part required to be submitted under Sec. 57.203(b) (eligibility),
directly to the appropriate EPA Regional Office.
(b) When application is made to the appropriate State or local
agency, the smelter owner shall submit one complete copy of all parts of
the application required to be submitted under this subpart to that
agency, in addition to the application requirements contained in
paragraph (a) of this section. If the smelter owner is requesting an
advance eligibility determination pursuant to Sec. 57.203(b), such
request must be made in writing and shall accompany the copy of the
application being sent to the Director of the Stationary Source
Compliance Division of the Environmental Protection Agency.
(c) If the smelter owner is requesting a waiver of the interim
constant control requirement of Sec. 57.301, such request must be sent
directly to the Director, Stationary Source Compliance Division, at the
time of application, in accordance with Sec. 57.802.
(d) The NSO Process. (1) A smelter desiring an NSO shall apply for
an NSO by submitting an application under subpart B including the
financial information required in appendix A and including the
information necessary to make the determinations required by this
subparagraph and Sec. 57.201(d)(2). The issuing agency shall analyze the
financial information according to the financial eligibility test
prescribed by subpart A and described in appendix A. The issuing Agency
shall then determine whether the smelter is able to comply with its SIP
on or before the date required in the SIP by installing adequately
demonstrated technology which is reasonably available. See also
Sec. 57.102(a)(3). If the test demonstrates that adequately demonstrated
technology is not reasonably available to the smelter to allow it to
comply with the SIP by the required compliance date, the smelter is
eligible for an NSO.
(2)(i) If the smelter is determined to be eligible for an NSO under
paragraph (d)(1) of this section, the issuing Agency shall apply the
appendix A financial eligibility tests again before issuing an NSO in
order to determine if the smelter can comply with its SIP requirements
on or before January 1, 1988 by installing adequately demonstrated
technology which is reasonably available.
(ii) If application of the tests shows that the smelter could comply
by or before January 1, 1988, the issuing agency shall notify the
smelter of this determination, and shall not issue an NSO to the smelter
unless the NSO contains a SIP compliance schedule meeting the
requirements of Sec. 57.705. Such a compliance schedule must provide for
compliance with the smelter's SO2 SIP as expeditiously as
practicable and in no case later than January 1, 1988. A smelter must
submit to the issuing agency information necessary to determine a
compliance schedule meeting the requirements of Sec. 57.705. This
information shall be submitted by a smelter within thirty days after the
smelter is notified by the issuing agency that a SIP compliance schedule
is required. The Administrator may consider an NSO application to be
withdrawn for SIP enforcement purposes if a smelter fails to submit such
information within the time required under this paragraph.
(iii) If no adequately demonstrated technology is found to be
reasonably available to enable a smelter to comply by January 1, 1988,
it would be excused from the compliance schedule requirement in
Sec. 57.201(d)(2)(ii), but it would be subject to reevaluation of its
ability to comply by that date at any time during the term of the NSO.
(See Sec. 57.201(d)(3)).
(3) At any time during the term of an NSO which does not contain a
SIP compliance schedule, EPA or the issuing agency may reevaluate the
availability of technology to the smelter. If EPA or the issuing agency
determines that adequately demonstrated technology is reasonably
available to permit the smelter to comply with its SIP by or before
January 1, 1988, the NSO shall be amended within 3 months time after
such determination. The amendment shall require compliance with all SIP
requirements by or before January 1, 1988, and shall include a
[[Page 137]]
compliance schedule meeting the requirements of Sec. 57.705. The
determination that adequately demonstrated technology is reasonably
available shall be made by reapplying the same appendix A financial
eligibility tests required by subpart B, updated by economic data
reflecting current operating conditions and currently demonstrated
control technology. Any such determination and amendment shall be
governed by the provisions of this part and section 119 of the Clean Air
Act.
(4) Notice and opportunity for public hearing in accordance with
section 119 of the Clean Air Act must be provided before issuance of any
NSO.
(e) A smelter that does not have any constant SO2
controls or whose existing constant SO2 controls when in full
operation and optimally maintained are not sufficient to treat all
strong SO2 streams may apply for a waiver of the requirements
of subpart C to install interim constant controls by submitting an
application under subpart H. A waiver may be granted only with respect
to the requirement to eliminate bypass of constant controls through the
installation of new constant control equipment, not with respect to the
requirements for optimum maintenance and operation of existing
equipment. EPA shall then determine the smelter's ability to afford
installation of the required additional interim constant SO2
control equipment at the smelter based on financial eligibility
information analyzed according to the financial test prescribed in
appendix A. A waiver of the requirement for additional interim constant
controls will be granted if EPA determines in accordance with the
procedures of subpart H that imposition of this requirement would
necessitate closure of the smelter for at least one year.
Sec. 57.202 How to apply.
(a) Letter of intent. To initiate an application for an NSO, the
owner or operator of a smelter shall send a letter of intent to an
appropriate air pollution control agency. The letter of intent shall
contain a statement of the owner's intent to apply for an NSO, and an
agreement to provide any information required under this part. The
letter of intent shall be signed by a corporate official authorized to
make such commitments. Upon receipt of any letter of intent by the
issuing agency, the SIP emission limitation for sulfur dioxide, as to
that applicant, shall be deemed suspended for 60 days. The 60 day
suspension may be extended for good cause at the discretion of the
Administrator.
(b) Complete application. (1) Within the period referred to in
paragraph (a) of this section, the smelter owner shall submit its
completed application pursuant to Sec. 57.201. Receipt of all parts of a
substantially complete application postmarked within the original or
extended application period shall be deemed to continue the suspension
of the SIP emission limitation for SO2 until the issuing
agency issues or declines to issue an NSO. This suspension shall in all
cases terminate, however, 90 days after receipt of the substantially
completed application, unless extended for good cause at the discretion
of the Administrator. If, in the Administrator's judgment, good faith
effort has been made to submit a complete application, additional time
may be granted to allow for correction of minor deficiencies.
(2) If an issuing agency transmits an NSO to EPA for approval before
the expiration of the suspension of the Federal SIP emission limitation,
the suspension shall continue until EPA approves or disapproves the NSO.
Sec. 57.203 Contents of the application.
(a) Claim of confidentiality. The smelter owner may make a business
confidentiality claim covering all or part of the information in the NSO
application in accordance with 40 CFR part 2, subpart B (41 FR 36906 et
seq., Sept. 1, 1976 as amended by 43 FR 39997 et seq., Sept. 8, 1978). A
claim is effective only if it is made at the time the material is
submitted to the issuing agency or EPA. A claim shall be made by
attaching to the information a notice of confidentiality. Information
claimed as confidential will be handled by EPA under the provisions of
40 CFR part 2, subpart B. If no claim accompanies the information, it
may be made available to the public without further notice.
[[Page 138]]
(b) Each smelter owner shall make the showing required by
Sec. 57.102(a)(3) by completing and submitting appendix A to this part
and any necessary supplemental information to the issuing agency as a
part of its application. Each smelter shall also submit as part of its
application the information which, in conjunction with the information
required by appendix A, is necessary for the issuing agency to make the
determination required by Sec. 57.201(d)(2). Any smelter owner or State
may, at its option, simultaneously submit this material to EPA for an
advance eligibility determination.
(c) Current operating information. A complete NSO application shall
also contain the following information:
(1) A process flow diagram of the smelter, including current process
and instrumentation diagrams for all processes or equipment which may
emit or affect the emission of sulfur dioxide; the characteristics of
all gas streams emitted from the smelter's process equipment (flow
rates, temperature, volumes, compositions, and variations over time);
and a list of all monitoring data and strip charts, including all data,
charts, logs or sheets kept with respect to the operation of any process
equipment which may emit or affect the emission of sulfur dioxide;
(2) The smelter's maximum daily production capacity (as defined in
Sec. 57.103(r)), the operational rate (in pounds of concentrate charged
to the smelting furnace per hour) of each major piece of process
equipment when the smelter is operating at that capacity; and the
smelter's average and maximum daily production rate for each product,
co-product, or by-product, by year, for the past four years;
(3) The optimal conversion efficiency (defined in terms of percent
of total SO2 removed from the input flow stream) of any acid
plant or other sulfur dioxide control system under the normal process
operating conditions (excluding malfunctions) most conducive to optimal
conversion efficiency;
(4) The average conversion efficiency of any acid plant or other
sulfur dioxide control system during normal process operations
(excluding malfunctions), by month, during the past four years.
(5) The percent of the time the acid plant or other control system
was available for service during each month for the past four years,
excluding downtime for scheduled maintenance, and a full explanation of
any major or recurring problems with the system during that time;
(6) The frequency and duration of times during the past four years
when the SO2 system was unavailable because of scheduled
maintenance of the system;
(7) A description of all scheduled, periodic, shutdowns of the
smelter during the past four years, including their purpose, frequency
and duration; and the same information with respect to unscheduled
shutdowns;
(8) The gas volume, rates, and SO2 concentration which
the control system was actually designed to accommodate, taking into
account any modifications made after its installation;
(9) The average monthly sulfur balance across the process and
control equipment, including fugitive emissions, for the past 4 years;
and
(10) A description of engineering techniques now in use at the
smelter to prevent the release of fugitive emissions into the atmosphere
at low elevations.
(d) The smelter owner's proposals. The smelter owner shall submit as
part of its application, draft NSO provisions which would implement the
requirements of subparts C through G of this part. The issuing agency
may use these proposals as the basis for any NSO that may be granted, or
may modify these proposals in any way it deems necessary in order to
comply with the requirements of this part.
(e) A smelter may submit as part of its application, information
necessary to determine any SIP compliance schedule which might be
required under Sec. 57.201(d)(2).
(f) Additional information. The smelter owner shall designate in its
application a corporate officer responsible and authorized to supply
supplemental technical and economic information and explanations as
required by the issuing agency during the formulation of the
[[Page 139]]
NSO. Failure to supply such information and explanations shall
constitute a failure to submit a complete application.
(g) Request for a waiver of constant controls. Any request for a
waiver of the requirement interim constant control of all strpmg streams
of Sec. 57.301 shall be made in accordance with Sec. 57.802. The
criteria and procedures for granting the waiver are governed by subpart
H of this part.
(h) Unless a smelter applies for a waiver in accordance with subpart
H, a smelter shall submit as part of its application a proposed schedule
for compliance with the interim constant control requirements of subpart
C which satisfies the requirements of Sec. 57.702.
Sec. 57.204 EPA action on second period NSOs which have already been issued.
(a) EPA may approve a second period NSO issued by a State before the
date of publication of these regulations in the Federal Register,
without requiring a complete reapplication under this subpart and new
State proceedings, provided:
(1) The second period NSO was issued by the State consistent with
the procedural requirements of section 119 of the Clean Air Act;
(2) EPA can make a determination that the smelter is eligible for a
second period NSO and whether the smelter can comply with its
SO2 SIP limits on or before January 1, 1988 under the
financial eligibility tests in these regulations on the basis of
available information and such supplementary information as the Agency
may request the smelter to submit; and
(3) The provisions of the NSO are consistent with the requirements
of these regulations.
(b) Should EPA require a smelter to submit information before taking
final action on an NSO referred to in paragraph (a), of this section, it
shall specify a reasonable period for submission of such information in
light of the nature of the information being required. The duration of
such period shall not exceed the period allowed for submission of a
complete application under Sec. 57.202 (a) and (b).
(c) The Agency shall consider the SIP emission limitation for
SO2 to be suspended with respect to a smelter which received
an NSO described in subpart A until EPA takes final action on such NSO.
Such suspension shall terminate if the smelter does not submit
supplementary information within the time specified under paragraph (b).
Sec. 57.205 Submission of supplementary information upon relaxation of an SO2 SIP emission limitation.
(a) In the event an SO2 SIP limit is relaxed subsequent
to EPA approval or issuance of a second period NSO, the smelter issued
the NSO shall submit to the issuing agency and EPA such supplementary
information that EPA considers appropriate for purposes of determining
whether the means of compliance with the new SIP limit are adequately
demonstrated to be reasonably available under the financial eligibility
tests specified in Sec. 57.102(b)(3). The smelter shall submit such
information within sixty days of notification by EPA. This time limit
may be extended by EPA for good cause.
(b) Upon receipt of any supplementary information required under
paragraph (a), the issuing agency shall promptly reevaluate the
availability of the means of compliance with the new SIP limit under the
NSO eligibility tests specified in Sec. 57.102(b)(3). If the issuing
agency determines that the demonstrated control technology necessary to
attain the new SO2 SIP limit is adequately demonstrated to be
reasonably available under the eligibility tests, so as to permit the
smelter to comply with the new SIP limit on or before January 1, 1988,
the NSO shall be amended within the time contemplated by Sec. 57.202(a)
after receipt of the supplementary information. Such amendment shall
require compliance with the new SO2 SIP limit as
expeditiously as practicable in accordance with Sec. 57.201(d)(3). The
issuing agency, if not EPA, shall promptly submit its determination and
any necessary NSO amendments to EPA.
(c) EPA shall take action to approve or disapprove the issuing
agency's determination and NSO amendment, if
[[Page 140]]
any, within a reasonable time after receipt of such determination and
amendment.
(d) If EPA disapproves the issuing agency's determination or NSO
amendment, or if a smelter fails to submit any supplementary information
as required under paragraph (a), EPA and/or the issuing agency shall
take appropriate remedial action. EPA shall take appropriate remedial
action if the issuing agency does not make any determination and
amendment required by this section within the time contemplated by
Sec. 57.202(a).
Subpart C--Constant Controls and Related Requirements
Sec. 57.301 General requirements.
Each NSO shall require an interim level of sulfur dioxide constant
controls to be operated at the smelter, unless a waiver of this
requirement has been granted to the owner under subpart H of this part.
Except as otherwise provided in Sec. 57.304, the interim constant
controls shall be properly operated and maintained at all times. The NSO
shall require the following gas streams to be treated by interim
constant controls:
(a) In copper smelters, off-gases from fluidized bed roasters, flash
furnaces, NORANDA reactors, electric furnaces and copper converters;
(b) In lead smelters, off-gases from the front end of the sintering
machine and any other sinter gases which are recirculated;
(c) In zinc smelters, off-gases from mult-hearth roasters, flash
roasters and fluidized bed roasters; and
(d) In all primary nonferrous smelters, all other strong
SO2 streams.
(e) In all primary nonferrous smelters, any other process streams
which were regularly or intermittently treated by constant controls at
the smelter as of August 7, 1977.
Sec. 57.302 Performance level of interim constant controls.
(a) Maximum feasible efficiency. Each NSO shall require: that the
smelter operate its interim constant control systems at their maximum
feasible efficiency, including the making of any improvements necessary
to correct the effects of any serious deficiencies; that the process and
control equipment be maintained in the way best designed to ensure such
operation; and that process operations be scheduled and coordinated to
facilitate treatment of process gas streams to the maximum possible
extent. Maximum feasible efficiency shall be expressed in the NSO in the
form of a limitation on the concentration of SO2 in the tail
gas of each individual control system in combination with an appropriate
averaging period, as provided below in paragraphs (b) and (c) of this
section.
(b) The limitation level for SO2 concentration in the
control system tail gas. The level at which the concentration limitation
is set shall take into account fluctuations in the strength and volume
of process off-gases to the extent that those fluctuations affect the
SO2 content of the tail gas and cannot be avoided by improved
scheduling and coordination of process operations. The limitation shall
exclude the effect of any increase in emissions caused by process or
control equipment malfunction. The limitation shall take into account
unavoidable catalyst deterioration in sulfuric acid plants, but may
prescribe the frequency of catalyst screening or replacement. The NSO
shall also prohibit the smelter owner from using dilution air to meet
the limitation.
(c) Averaging period. (1) The averaging period shall be derived in
combination with the concentration limitation and shall take into
account the same factors described in paragraph (b). The averaging
period established under this paragraph should generally not exceed the
following:
(i) For sulfuric acid plants on copper smelters, 12-hour running
average;
(ii) For sulfuric acid plants on lead smelters, 6-hour running
average;
(iii) For sulfuric acid plants on zinc smelters, 2-hour running
average;
(iv) For dimethylaniline (DMA) scrubbing units on copper smelters,
2-hour running average.
(2) A different averaging period may be established if the applicant
demonstrates that such a period is necessary in order to account for the
factors described in paragraph (b) of this
[[Page 141]]
section: Provided, that the period is enforceable and satisfies the
criteria of paragraph (a) of this section.
(d) Improved performance. (1) The performance level representing
maximum feasible efficiency for any existing control system (e.g., a
sulfuric acid plant or a DMA scrubber) shall require the correction of
the effects of any serious deficiencies in the system. For the purpose
of this paragraph, at least the following problems shall constitute
serious deficiencies in acid plants:
(i) Heat exchangers and associated equipment inadequate to sustain
efficient, autothermal operation at the average gas strengths and
volumes received by the acid plant during routine process equipment
operation;
(ii) Failure to completely fill all available catalyst bed stages
with sufficient catalyst;
(iii) Inability of the gas pre-treatment system to prevent unduly
frequent plugging or fouling (deterioration) of catalyst or other
components of the acid plant; or
(iv) Blower capacity inadequate to permit the treatment of the full
volume of gas which the plant could otherwise accommodate, or in-leakage
of air into the flues leading to the plant, to the extent that this
inadequacy results in bypassing of gas around the plant.
(2) Notwithstanding any contrary provisions of Sec. 57.304(c)
(malfunction demonstration), no excess emissions (as defined in
Sec. 57.304(a)) shall be considered to have resulted from a malfunction
in the constant control system if the smelter owner has not upgraded
serious deficiencies in the constant control system in compliance with
the requirements of Sec. 57.302(d)(1), unless the smelter owner
demonstrates under Sec. 57.304(c) that compliance with those
requirements would not have affected the magnitude of the emission.
(e) Multiple control devices. (1) At any smelter where off-gas
streams are treated by various existing control systems (e.g., multiple
acid plants or a DMA scrubber and an acid plant), the NSO shall require
the use of those systems in the combination that will result in the
maximum feasible net SO2 removal.
(2) To the extent that compliance with this requirement is
demonstrated by the smelter operator to result in excess emissions
during unavoidable start up and shut down of the control systems, those
excess emissions shall not constitute violations of the NSO.
Sec. 57.303 Total plantwide emission limitation.
(a) Calculation of the emission limitation. Each NSO shall contain a
requirement limiting the total allowable emissions from the smelter to
the level which would have been associated with production at the
smelter's maximum production capacity (as defined in Sec. 57.103(r)) as
of August 7, 1977. This limitation shall be expressed in units of mass
per time and shall be calculated as the sum of uncontrolled process and
fugitive emissions, and emissions from any control systems (operating at
the efficiency prescribed under Sec. 57.302). These emission rates may
be derived from either direct measurements or appropriately documented
mass balance calculations.
(b) Compliance with the emission limitation. Each NSO shall require
the use of specific, enforceable testing methods and measurement periods
for determining compliance with the limitation established under
paragraph (a) of this section.
Sec. 57.304 Bypass, excess emissions and malfunctions.
(a) Definition of excess emissions. For the purposes of this
subpart, any emissions greater than those permitted by the NSO
provisions established under Sec. 57.302 (performance level of interim
constant controls) or Sec. 57.303 (plantwide emission limitation) of
this subpart shall constitute excess emissions. Emission of any gas
stream identified under Sec. 57.301 (a), (b), (c), (d) or (e) of this
subpart that is not treated by a sulfur dioxide constant control system
shall also constitute an excess emission under this subpart.
(b) The excess emission report. Each NSO shall require the smelter
to report all excess emissions to the issuing agency, as provided in
Sec. 57.305(b). The report shall include the following:
[[Page 142]]
(1) Identity of the stack or other emission points where the excess
emissions occurred;
(2) Magnitude of the excess emissions expressed in the units of each
applicable emission limitation, as well as the operating data,
documents, and calculations used in determining the magnitude of the
excess emissions;
(3) Time and duration of the excess emissions;
(4) Identity of the equipment causing the excess emissions;
(5) Nature and cause of such excess emissions;
(6) Steps taken to limit the excess emissions, and when those steps
were commenced;
(7) If the excess emissions were the result of a malfunction, the
steps taken to remedy the malfunction and to prevent the recurrence of
such malfunction; and
(8) At the smelter owner's election, the demonstration specified in
paragraph (c) of this section.
(c) Malfunction demonstration. Except as provided in
Sec. 57.302(e)(2) or in paragraph (d) or (e) of this section, any excess
emission shall be a violation of the NSO unless the owner demonstrates
in the excess emissions report required under paragraph (b) of this
section that the excess emission resulted from a malfunction (or an
unavoidable start up and shut down resulting from a malfunction) and
that:
(1) The air pollution control systems, process equipment, or
processes were at all times maintained and operated, to the maximum
extent practicable, in a manner consistent with good practice for
minimizing emissions;
(2) Repairs were made as expeditiously as practicable, including the
use of off-shift labor and overtime;
(3) The amount and duration of the excess emissions were minimized
to the maximum extent practicable during periods of such emissions; and
(4) The excess emissions were not part of a recurring pattern
indicative of serious deficiencies in, or inadequate operation, design,
or maintenance of, the process or control equipment.
(d) Scheduled maintenance exception. Excess emissions occurring
during scheduled maintenance shall not constitute violations of the NSO
to the extent that:
(1) The expected additional annual sulfur dioxide removal by any
control system (including associated process changes) for which
construction had not commenced (as defined in 40 CFR 60.2 (g) and (i))
as of August 7, 1977 and which the smelter owner agrees to install and
operate under subpart F, would have offset such excess emissions if the
system had been in operation throughout the year in which the
maintenance was performed;
(2) The system is installed and operated as provided in the NSO
provisions established under subpart F; and
(3) The system performs at substantially the expected efficiency and
reliability subsequent to its initial break-in period.
(e) An NSO may provide that excess emissions which occur during acid
plant start-up as the result of the cooling of acid plant catalyst due
to the unavailability of process gas to an acid plant during a prolonged
SCS curtailment or scheduled maintenance are not excess emissions. If
the NSO does so provide, it shall also require the use of techniques or
practices designed to minimize these excess emissions, such as the
sealing of the acid plant during prolonged curtailments, the use of
auxiliary heat or SO2 injected during the curtailment, or the
preheating of the acid plant before start-up of the process equipment it
serves.
(f) Requirements for a smelter with constant controls that applies
for a waiver.
(1) If a smelter that has some interim constant controls applies for
a waiver in accordance with subpart H, the following requirements shall
apply pending action on the waiver application and following final
action granting or approving a waiver:
(i) The NSO shall require the smelter to implement maintenance and
operation measures designed to reduce to the maximum extent feasible the
potential for bypass of existing interim constant controls.
[[Page 143]]
(ii) Upon application for a waiver under subpart H, the smelter
shall submit to the issuing agency for its approval and to EPA proposed
maintenance and operation measures for compliance with the requirements
of paragraph (i).
(iii) The remainder of this subpart shall apply except that: (A) The
emission limitations required under this subpart shall be based only on
existing constant control equipment as upgraded through the improved
maintenance and operation required by this paragraph, and (B) bypass of
existing controls shall not constitute excess emissions, provided the
maintenance and operation requirements and emission limitations
prescribed by the NSO are satisfied.
(2) After any denial of a waiver by the issuing Agency, or any
disapproval by EPA of a waiver granted by the issuing agency, the NSO
shall be amended consistent with the requirements of this subpart and
Sec. 57.702.
Sec. 57.305 Compliance monitoring and reporting.
(a) Monitoring. (1) Each NSO shall require compliance with the
control system performance requirements established pursuant to this
subpart to be determined through the use of continuous monitors for
measuring SO2 concentration.
(i) Such monitors must be installed, operated and maintained in
accordance with the performance specifications and other requirements
contained in appendix D to 40 CFR part 52 or part 60. The monitors must
take and record at least one measurement of SO2 concentration
from the effluent of each control system in each 15-minute period.
Failure of the monitors to record at least 95% of the 15-minute periods
in any 30-day period shall constitute a violation of the NSO.
(ii) The sampling point shall be located at least 8 stack diameters
(diameter measured at sampling point) downstream and 2 diameters
upstream from any flow disturbance such as a bend, expansion,
constriction, or flame, unless another location is approved by the
Administrator.
(iii) The sampling point for monitoring emissions shall be in the
duct at the centroid of the cross section if the cross sectional area is
less than 4.645m2 (50 ft2) or at a point no closer
to the wall than 0.914m (3 ft) if the cross sectional area is
4.645m2 (50 ft2) or more. The monitor sample point
shall be in an area of small spatial concentration gradient and shall be
representative of the concentration in the duct.
(iv) The measurement system(s) installed and used pursuant to this
paragraph shall be subject to the manufacturer's recommended zero
adjustment and calibration procedures at least once per 24-hour
operating period unless the manufacturer specifies or recommends
calibration at shorter intervals, in which case such specifications or
recommendations shall be followed. Records of these procedures shall be
made which clearly show instrument readings before and after zero
adjustment and calibration.
(2) Each NSO shall require the monitoring of any ducts or flues used
to bypass gases, required under this subpart to be treated by constant
controls, around the smelter's sulfur dioxide constant control system(s)
for ultimate discharge to the atmosphere. Such monitoring shall be
adequate to disclose the time of the bypass, its duration, and the
approximate volume and SO2 concentration of gas bypassed.
(b) Reporting. (1) Each NSO shall require that the smelter maintain
a record of all measurements required under paragraph (a) of this
section. Results shall be summarized monthly and shall be submitted to
the issuing agency within 15 days after the end of each month. The
smelter owner shall retain a record of such measurements for one year
after the NSO period terminates.
(2) Each NSO shall require that the smelter maintain a record of all
measurements and calculations required under Sec. 57.303(b). Results
shall be summarized on a monthly basis and shall be submitted to the
issuing agency at 6-month intervals. The smelter owner shall retain a
record of such measurements and calculations for at least one year after
the NSO terminates.
(3) The report required under Sec. 57.304(b) shall accompany the
report required under paragraph (b)(1) of this section.
[[Page 144]]
(c) Quality assurance and continuous data--(1) Quality assurance.
Each NSO shall require that the smelter submit a plan for quality
assurance to the issuing agency for approval and that all monitoring
performed by continuous monitors shall be verified for quality assurance
by the smelter. Such plans must follow current EPA guidelines for
quality assurance, in order to be approvable.
(2) Continuous data. Manual source testing methods equivalent to 40
CFR part 60, appendix A shall be used to determine compliance if the
continuous monitoring system malfunctions.
Subpart D--Supplementary Control System Requirements
Sec. 57.401 General requirements.
Except as provided in subpart E, each NSO shall require the smelter
owner to prevent all violations of the NAAQS in the smelter's designated
liability area (DLA) through the operation of an approved supplementary
control system (SCS).
Sec. 57.402 Elements of the supplementary control system.
Each supplementary control system shall contain the following
elements:
(a) Air quality monitoring network. An approvable SCS shall include
the use of appropriate ambient air quality monitors to continuously
measure the concentration of sulfur dioxide in the air in the smelter's
DLA.
(1) The monitors shall be located at all points of expected
SO2 concentrations necessary to anticipate and prevent
possible violations of NAAQS anywhere in the smelter's DLA. The
determination of the locations where such concentrations may occur shall
take into account all recorded or probable meteorological and operating
conditions (including bypassing of control equipment), as well as the
presence of other sources of SO2 significantly affecting
SO2 concentrations in the DLA.
(2) The number and location of sites shall be based on dispersion
modeling, measured ambient air quality data, meteorological information,
and the results of the continuing review required by paragraph (f) of
this section. The system shall include the use of at least 7 fixed
monitors unless the issuing agency determines, on the basis of a
demonstration by the smelter owner, that the use of fewer monitors would
not limit coverage of points of high SO2 concentration or
otherwise reduce the capability of the smelter owner to prevent any
violations of the NAAQS in the smelter's DLA.
(3) All monitors shall be continuously operated and maintained and
shall meet the performance specifications contained in 40 CFR part 53.
The monitors shall be capable of routine real time measurement of
maximum expected SO2 concentrations for the averaging times
of SO2 NAAQS.
(b) Meteorological network. The SCS must have a meteorological
assessment capability adequate to predict and identify local conditions
requiring emission curtailment to prevent possible violations of the
NAAQS. The meteorological assessment capability shall provide all
forecast and current information necessary for successful use of the SCS
operational manual required by paragraph (e) of this section.
(c) Designated liability area. The system shall be required to
prevent all violations of the NAAQS within the smelter's DLA. The DLA of
any smelter is the area within which the smelter's emissions may cause
or significantly contribute to violations of the NAAQS for
SO2 when the smelter is operating at its maximum production
capacity under any recorded or probable meterological conditions. The
boundaries of that area shall be specified in the NSO.
(1) Unless an acceptable demonstration is made under paragraph
(c)(2) of this section, the DLA shall be a circle with a center point at
the smelter's tallest stack and a minimum radius as given in the
following table:
Radius for SO2 Emissions at Maximum Production Capacity \1\
------------------------------------------------------------------------
Emission rate in Radius in
Emissions rate in tons per hour grains per sec. kilometers
------------------------------------------------------------------------
16 or less.......................... 4,000 or less......... 11
24.................................. 6,000................. 16
32.................................. 8,000................. 24
40.................................. 10,000................ 32
[[Page 145]]
48 or more.......................... 12,000 or more........ 40
------------------------------------------------------------------------
\1\ Maximum emission rates for periods not to exceed 24 hours. Minimum
radii may be determined from the table by linear interpolation.
(2) The NSO may provide for a DLA with different boundaries if the
smelter owner can demonstrate through the use of appropriate dispersion
modeling and ambient air quality monitoring data that the smelter's
controlled emissions could not cause or significantly contribute to a
violation of the NAAQS beyond the boundaries of such a different area
under any recorded or probable meteorological conditions.
(3) A violation of the NAAQS in the DLA of any smelter shall
constitute a violation of that smelter's NSO, unless the issuing agency
determines on the basis of a showing by the smelter owner that the
smelter owner had taken all emission curtailment action indicated by the
SCS operational manual and that the violation was caused in significant
part by:
(i) Emissions of another source(s) which were in excess of the
maximum permissible emissions applicable to such source(s),
(ii) Fugitive emissions of another source(s), or
(iii) The smelter's own fugitive emissions: Provided, that the
smelter is in compliance with all requirements of or under subpart E of
this part.
(4) For the purposes of this section, maximum permissible emissions
for other sources are the highest of:
(i) SIP emission limitation;
(ii) Orders in effect under section 113(d) of the Clean Air Act; or
(d) Overlapping designated liability areas. Notwithstanding any
other provisions of this subpart, the following requirements shall apply
whenever the designated liability areas of 2 or more smelters do, or
may, overlap:
(1) In the case of any NSO applicant that would have a DLA which
would overlap with the DLA of any other smelter that has applied for an
NSO or has an NSO in effect, the NSO applicant shall include in its
application an enforceable joint plan, agreed to by such other
smelter(s). In determining whether a joint plan is required, the NSO
applicant shall calculate its DLA according to the table in paragraph
(c)(1) of this section. The DLA of the other smelter shall be calculated
according to the table in paragraph (c)(1) unless the other smelter has
an NSO in effect, in which case the boundaries in that NSO shall be
used. The enforceable joint plan shall provide for:
(i) Emission curtailment adequate to ensure that the NAAQS will not
be violated in any areas of overlapping DLAs; and
(ii) Conclusive prospective allocation of legal liability in the
event that the NAAQS are violated in the area of overlapping DLAs.
Such plans may, but need not, include the operation of a joint SCS
system. Each NSO shall require adherence by the NSO applicant owner to
the joint plan for emission curtailment and allocation of liability,
unless the issuing agency determines, pursuant to the provisions of
paragraph (c)(2) of this section, that the NSO applicant's DLA does not
overlap with that of any other smelter.
(2) In the case of any NSO applicant that would have a DLA which
would overlap with the DLA of any other smelter whose owner has not
applied for an NSO (and does not have an NSO in effect), the NSO
applicant's submittal shall contain a written consent, signed by a
corporate official empowered to do so. The consent shall state that if,
at any time thereafter, the owner of the other smelter applies for an
NSO, and the other smelter's DLA would overlap with the NSO applicant's
DLA, the NSO applicant will negotiate and submit an enforceable joint
plan for emission curtailment and allocation of liability (as described
in paragraph (d)(1) of this section). In determining whether it is
necessary to submit such a consent, each smelter's DLA shall be
calculated according to the table set forth in paragraph (c)(1) of this
section. The consent shall state that a joint plan shall be submitted
within 90 days of the issuing agency's notification to the NSO applicant
of receipt of the other smelter's letter of intent, unless the issuing
agency determines that the DLAs do not overlap.
[[Page 146]]
Failure of the NSO applicant to submit such a plan shall constitute
grounds for denial of its NSO application or a violation of an effective
NSO, as applicable.
(e) The SCS operational manual. Each NSO shall require the smelter
to be operated in accordance with the provisions of an SCS operational
manual approved by the issuing agency. The SCS operational manual shall
describe the circumstances under which, the extent to which, and the
procedures through which emissions shall be curtailed to prevent
violations of the NAAQS in the smelter's DLA. Failure to curtail
emissions when and as much as indicated by the manual or to follow the
provisions of the manual implementing the requirements of paragraph
(e)(3) of this section shall constitute a violation of the NSO.
(1) The operational manual shall prescribe emission curtailment
decisions based on the use of real time information from the air quality
monitoring network dispersion model estimates of the effect of emissions
on air quality, and meteorological observations and predictions.
(2) The operational manual shall also provide for emission
curtailment to prevent violation of the NAAQS within the smelter's DLA
which may be caused in part by stack emissions, and to the extent
practicable fugitive emissions, from any other source (unless that other
source is a smelter subject to an NSO).
(3) The SCS operational manual shall include (but not be limited
to):
(i) A clear delineation of the authority of the SCS operator to
require all other smelter personnel to implement the operator's
curtailment decisions;
(ii) The maintenance and calibration procedures and schedules for
all SCS equipment;
(iii) A description of the procedures to be followed for the regular
acquisition of all meteorological information necessary to operate the
system;
(iv) The ambient concentrations and meteorological conditions that
will be used as criteria for determining the need for various degrees of
emission curtailment;
(v) The meteorological variables as to which judgments may be made
in applying the criteria stated pursuant to paragraph (e)(3)(iv) of this
section;
(vi) The procedures through which and the maximum time period within
which a curtailment decision will be made and implemented by the SCS
operator;
(vii) The method for immediately evaluating the adequacy of a
particular curtailment decision, including the factors to be considered
in that evaluation;
(viii) The procedures through which and the time within which
additional necessary curtailment will immediately be effected; and
(ix) The procedures to be followed to protect the NAAQS in the event
of a mechanical failure in any element of the SCS.
(f) Continuing review and improvement of the SCS. Each NSO shall
require the smelter owner to conduct an active program to continuously
review the design and operation of the SCS to determine what measures
may be available for improving the performance of the system. Among the
elements of this program shall be measures to locate and examine
possible places both inside and outside the DLA where unmonitored NAAQS
violations may be occurring. Such measures shall include the use of
modeling as appropriate and mobile ambient air quality monitors,
following up on information and complaints from members of the public,
and other appropriate activities. The NSO shall also require the
submission of a semi-annual report to the issuing agency detailing the
results of this review and specifying measures implemented to prevent
the recurrence of any violations of NAAQS.
Sec. 57.403 Written consent.
(a) The consent. The NSO shall include a written consent, signed by
a corporate official empowered to do so, in the following form:
As a condition of receiving a Primary Nonferrous Smelter Order (NSO)
under Section 119 of the Clean Air Act, for the smelter operated by
(name of company) at (location), the undersigned official, being
empowered to do so, consents for the company as follows:
(1) In any civil proceeding (judicial or administrative) to enforce
the NSO, the company will not contest:
[[Page 147]]
(a) Liability for any violation of the National Ambient Air Quality
Standards for sulfur dioxide in the smelter's designated liability area
(DLA), except on the ground that a determination under 40 CFR
57.402(c)(3) was clearly wrong; or
(b) The conclusive allocation of liability under NSO provisions
satisfying 40 CFR 57.402(d)(1) between the company's smelter and any
other smelter(s) for any violation of the National Ambient Air Quality
Standards for sulfur dioxide in an area of overlapping DLAs.
(2) The issuing agency (as defined in 40 CFR 57.103) will be allowed
unrestricted access at reasonable times to inspect, verify calibration
of, and obtain data from ambient air quality monitors operated by the
company under the requirements of the NSO.
(b) Rights not waived by the consent. This consent shall not be
deemed to waive any right(s) to judicial review of any provisions of an
NSO that are otherwise available to the smelter owner or operator under
section 307(b) of the Clean Air Act.
Sec. 57.404 Measurements, records, and reports.
(a) Measurements. Each NSO shall require the smelter owner to
install, operate, and maintain a measurement system(s) for continuously
monitoring sulfur dioxide emissions and stack gas volumetric flow rates
in each stack (except a stack used exclusively for bypassing control
equipment) which could emit 5 percent or more of the smelter's total
potential (uncontrolled) hourly sulfur dioxide emissions.
(1) Such monitors shall be installed, operated, and maintained in
accordance with the performance specifications and other requirements
contained in appendices D and E to 40 CFR part 52. The monitors must
take and record at least one measurement of sulfur dioxide concentration
and stack gas flow rate from the effluent of each affected stack in each
fifteen-minute period. (The NSO shall require the smelter operator to
devise and implement any procedures necessary for compliance with these
performance specifications.)
(2) The sampling point shall be located at least eight stack
diameters (diameter measured at sampling point) downstream and two
diameters upstream from any flow disturbance such as a bend, expansion,
constriction, or flame, unless another location is approved by the
Administrator.
(3) The sampling point for monitoring emissions shall be in the duct
at the centroid of the cross section if the cross sectional area is less
than 4.645 m2 (50 ft 2) or at a point no closer to
the wall than 0.914m (3 ft) if the cross sectional area is 4.645
m2 (50 ft2) or more. The monitor sample point
shall be in an area of small spatial concentration gradient and shall
provide a sample which is representative of the concentration in the
duct.
(4) The measurement system(s) installed and used pursuant to this
paragraph shall be subject to the manufacturer's recommended zero
adjustment and calibration procedures at least once per 24-hour
operating period unless the manufacturer specifies or recommends
calibration at shorter intervals, in which case such specifications or
recommendations shall be followed. Records of these procedures shall be
made which clearly show instrument readings before and after zero
adjustment and calibration.
(5) The results of such monitoring, calibration, and maintenance
shall be submitted in the form and with the frequency specified in the
NSO.
(b) Records. Each NSO shall require the smelter owner to maintain
records of the air quality measurements made, meteorological information
acquired, emission curtailment ordered (including the identity of the
persons making such decisions), and calibration and maintenance
performed on SCS monitors during the operation of the SCS. These records
shall be maintained for the duration of the NSO.
(c) Reports. Each NSO shall require the smelter owner to:
(1) Submit a monthly summary indicating all places and times at
which the NAAQS for SO2 were violated in the smelter's DLA,
and stating the SO2 concentrations at such times;
(2) Immediately notify EPA and the State agency any time
concentrations of SO2 in the ambient air in the smelter's DLA
reaches 0.3 part per million (800 micrograms/cubic meter), 24-hour
average, or exceed the warning stage in any more stringent emergency
plan in the applicable State Implementation Plan; and
[[Page 148]]
(3) Make such other reports as may be specified in the NSO.
Sec. 57.405 Formulation, approval, and implementation of requirements.
(a) SCS content of the application. The requirements of
Sec. 57.203(d) shall be satisfied with respect to this subpart as
follows:
(1) Each NSO application shall include a complete description of any
supplementary control system in operation at the smelter at the time of
application and a copy of any SCS operational manual in use with that
system.
(2) Each NSO application shall contain proposed NSO provisions for
compliance with the requirements of Secs. 57.401, 57.402 (c), (d), and
(f), 57.403, 57.404, and 57.405 (b)(2).
(3) Each NSO application shall include a specific plan for the
development of a system fulfilling the requirements of Sec. 57.402(a),
(b), and (e) (covering air quality monitoring network, meteorological
network, and the SCS operational manual).
(b) SCS content of the order. (1) Each NSO shall include an approved
version of the plan described in paragraph (a)(3) of this section and
shall provide increments of progress towards its completion. Each NSO
shall require, upon completion of the measures specified in the approved
plan, submission of a report which describes each element of the SCS and
explains why the elements satisfy the requirements of the plan and
submission of a copy of the SCS operational manual developed under the
plan.
(2) Each NSO shall require the submission of a final report, within
6 months of the required date for completion of the measures specified
in the approved plan evaluating the performance and adequacy of the SCS
developed pursuant to the approved plan. The report shall include:
(i) A detailed description of how the criteria that form the basis
for particular curtailment decisions were derived;
(ii) A complete description of each SCS element listed in
Sec. 57.402 (a) through (d) (covering monitoring, meteorology, and the
DLA), and an explanation of why the elements fulfill the requirements of
those sections;
(iii) A reliability study demonstrating that the SCS will prevent
violations of the NAAQS in the smelter's DLA at all times. The
reliability study shall include a comprehensive analysis of the system's
operation during one or more three-month seasonal periods when
meteorological conditions creating the most serious risk of NAAQS
violations are likely to occur. Where it is impossible, because of time
restraints, to include in such a study and analysis of the three month
seasonal period with meteorological conditions creating the most serious
risk of NAAQS violations, the study shall analyze the system's operation
on the basis of all available information. The NSO shall provide that in
such case, a supplemental reliability study shall be submitted after the
end of the worst case three-month period as a part of the next semi-
annual report required under Sec. 57.402(f).
(iv) A copy of the current SCS operational manual.
(c) Amendment of the NSO. Each NSO shall be amended, if necessary,
within 3 months of completion of the measures required under the SCS
development plan and also, if necessary, within three months of
submission of the final report or any supplement to the final report
required under paragraph (b)(2) of this section, to reflect the most
current approved elements of the SCS and, as appropriate, to fulfill all
other requirements of this subpart. Each NSO shall also be subsequently
amended (as provided in Sec. 57.104) whenever necessary as a result of
the program required by Sec. 57.402(f) or to reflect improved SCS
operating procedures or other system requirements.
Subpart E--Fugitive Emission Evaluation and Control
Sec. 57.501 General requirements.
(a) Each NSO shall require the smelter owner to use such control
measures as may be necessary to ensure that the smelter's fugitive
emissions do not result in violations of the NAAQS for SO2 in
the smelter's DLA.
[[Page 149]]
(b) A smelter which is operating under an NSO containing a SIP
compliance schedule established in accordance with Sec. 57.705 is
required to be making progress toward compliance with any fugitive
control requirements contained in its respective SIP and need not meet
the other requirements contained in this subpart.
(c) A smelter which is subject to an NSO which does not contain a
SIP compliance schedule must meet the provisions of Secs. 57.502 and
57.503.
Sec. 57.502 Evaluation.
(a) Evaluation at the time of application. Any smelter owner may
demonstrate at the time of application for an NSO that the smelter's
SO2 fugitive emissions will not cause or significant
contribute to violations of the NAAQS in the smelter's DLA. If such
demonstration is not made, the smelter owner shall submit the design and
workplan for a study adequate to assess the sources of significant
fugitive emissions from the smelter and their effects upon ambient air
quality.
(b) Evaluation during the first 6 months of the NSO. The design and
workplan of the study shall be approved, if adequate, by the issuing
agency and included in the NSO. The study shall commence no later than
the date when the NSO becomes effective and an analysis of its results
shall be submitted to the issuing agency within 6 months of the
effective date of the NSO. The study shall include an appropriate period
during which the ambient air shall be monitored to determine the impact
of fugitive emissions of sulfur dioxide, arsenic (at copper smelters
only), lead (at lead and zinc smelters only), and total suspended
particulates on the ambient air quality in the smelter's DLA.
Sec. 57.503 Control measures.
The NSO of any smelter subject to the requirements of Sec. 57.502(b)
shall be amended, if necessary, within 6 months of EPA's receipt of the
analysis specified in Sec. 57.502(b), as provided in Sec. 57.704(c) to
implement the requirement of Sec. 57.501. Measures required to be
implemented may include:
(a) Additional supplementary control. The use of the supplementary
control system, if the additional use of the system does not interfere
with the smelter owner's ability to meet the requirements of subpart D;
and
(b) Engineering and maintenance techniques. The use of engineering
and maintenance techniques to detect and prevent leaks and capture and
vent fugitive emissions through appropriate stacks. These techniques
include but are not limited to:
(1) For reactors, installation and proper operation of primary
hoods;
(2) For roasters, installation and proper operation of primary hoods
on all hot calcine transfer points;
(3) For furnaces, installation and proper operation of primary hoods
on all active matte tap holes, matte launders, slag skim bays, and
transfer points;
(4) For converters, installation and proper operation of primary
hoods for blowing operations, and where appropriate, secondary hoods for
charging and pouring operations;
(5) For sintering machines, installation and proper operation of
primary hoods on the sinter bed, all hot sinter ignition points, all

(6) For blast furnaces, installation and proper operation of primary
hoods on all active slag and lead bullion furnace tap holes and transfer
points;
(7) For dross reverberatory furnaces, installation and proper
operation of primary hoods on all active charging and discharging
points;
(8) Maintenance of all ducts, flues and stacks in a leak-free
condition to the maximum extent possible;
(9) Maintenance of all process equipment under normal operating
conditions in such a fashion that out-leakage of fugitive gases will be
prevented to the maximum extent possible;
(10) Secondary or tertiary hooding on process equipment where
necessary; and
(11) Partial or complete building evacuation as appropriate.
Sec. 57.504 Continuing evaluation of fugitive emission control measures.
Each NSO shall require the smelter owner to conduct an active
program to continuously review the effectiveness
[[Page 150]]
of the fugitive emission control measures implemented pursuant to
Sec. 57.503 in maintaining the NAAQS and, if such measures are not
sufficiently effective, to evaluate what additional measures should be
taken to assure that the NAAQS will be maintained with a reasonably
degree of reliability. The NSO shall also require submission of a semi-
annual report to the issuing Agency detailing the results of this review
and evaluation. Such a report may be submitted as part of the report
required under Sec. 57.402(f).
Sec. 57.505 Amendments of the NSO.
An NSO shall be amended within three months of submission of any
report required under Sec. 57.504 so as to require additional fugitive
emission control measures if such report establishes that such
additional measures are necessary to assure that the NAAQS will be
maintained with a reasonable degree of reliability.
Subpart F--Research and Development Requirements
Sec. 57.601 General requirements.
(a) This subpart is not applicable to NSOs which contain a SIP
compliance schedule in accordance with Sec. 57.705.
(b) The requirements of this subpart may be waived with respect to a
smelter if the owner of that smelter submits with its NSO application a
written certification by a corporate official authorized to make such a
certification that the smelter will either comply with its
SO2 SIP limits by January 2, 1988 or close after January 1,
1988 until it can comply with such limits.
(c) Except as provided in paragraphs (a) and (b), each NSO shall
require the smelter to conduct or participate in a specific research and
development program designed to develop more effective means of
compliance with the sulfur dioxide control requirements of the
applicable State Implementation Plan than presently exist.
Sec. 57.602 Approval of proposal.
(a) The smelter owner's proposal. The smelter owner's NSO
application shall include a proposed NSO provision for implementing the
requirement of Sec. 57.601, a fully documented supporting analysis of
the proposed program, and an evaluation of the consistency of the
proposed program with the criteria listed in Sec. 57.603. The
application shall also specify:
(1) The design and substantive elements of the research and
development program, including the expected amount of time required for
their implementation;
(2) The annual expected capital, operating, and other costs of each
element in the program;
(3) The smelter's current production processes, pollution control
equipment, and emissions which are likely to be affected by the program;
(4) Potential or expected benefits of the program;
(5) The basis upon which the results of the program will be
evaluated; and
(6) The names, positions, and qualifications of the individuals
responsible for conducting and supervising the project.
(b) EPA approval. (1) If the issuing agency will not be EPA, the
smelter owner or the issuing agency may also submit to EPA the
information specified in paragraph (a) of this section at the same time
the information is submitted to the issuing agency. As soon as possible
after the receipt of the information described in paragraph (a) of this
section, EPA shall certify to the issuing agency and to the applicant
whether or not in the judgment of the Administrator the smelter owner's
final proposals are approvable. If EPA does not receive an advance copy
of the proposal, the ultimate approval will occur when the NSO is
approved rather than in advance of receipt of the NSO.
(2) A prerequisite for approval of an R&D proposal by EPA and any
issuing agency is that the planned work must yield the most cost
effective technology possible.
(c) Optional preproposal. The smelter owner may, at its option,
submit to EPA for its approval and comment a preproposal generally
describing the project the owner intends to propose under paragraph (a)
of this section. A preproposal may be submitted to EPA any time prior to
the submission of a proposal under paragraph (a) of this section. As
soon as possible after the
[[Page 151]]
receipt of a preproposal, EPA shall certify to the applicant (and to any
other issuing agency, as applicable) whether or not the project would be
approvable. This certification may include comments indicating necessary
modifications which would make the project approvable.
Sec. 57.603 Criteria for approval.
The approvability of any proposed research and development program
shall be judged primarily according to the following criteria:
(a) The likelihood that the project will result in the use of more
effective means of emission limitation by the smelter within a
reasonable period of time and that the technology can be implemented at
the smelter in question, should the smelter be placed on a SIP
compliance schedule at some future date when adequately demonstrated
technology is reasonably available;
(b) Whether the proposed funding and staffing of the project appear
adequate for its successful completion;
(c) Whether the proposed level of funding for the project is
consistent with the research and development expenditure levels for
pollution control found in other industries;
(d) The potential that the project may yield industrywide pollution
control benefits;
(e) Whether the project may also improve control of other pollutants
of both occupational and environmental significance;
(f) The potential effects of the project on energy conservation; and
(g) Other non-air quality health and environmental considerations.
Sec. 57.604 Evaluation of projects.
The research and development proposal shall include a provision for
the employment of a qualified independent engineering firm to prepare
written reports at least annually which evaluate each completed
significant stage of the research and development program, including all
relevant information and data generated by the program. All reports
required by this paragraph shall be submitted to EPA and also to the
issuing agency if it is not EPA.
Sec. 57.605 Consent.
Each NSO shall incorporate by reference a binding written consent,
signed by a corporate official empowered to do so, requiring the smelter
owner to:
(a) Carry out the approved research and development program;
(b) Grant each issuing agency and EPA and their contractors access
to any information or data employed or generated in the research and
development program, including any process, emissions, or financial
records which such agency determines are needed to evaluate the
technical or economic merits of the program;
(c) Grant physical access to representatives and contractors of each
issuing agency to each facility at which such research is conducted;
(d) Grant the representatives and contractors of EPA and the issuing
agency reasonable access to the persons conducting the program on behalf
of the smelter owner for discussions of progress, interpretation of data
and results, and any other similar purposes as deemed necessary by EPA
or any issuing agency.
Sec. 57.606 Confidentiality.
The provisions of section 114 of the Act and 40 CFR part 2 shall
govern the confidentiality of any data or information provided to EPA
under this subpart.
Subpart G--Compliance Schedule Requirements
Sec. 57.701 General requirements.
This section applies to all smelters applying for an NSO. Each NSO
shall require the smelter owner to meet all of the requirements within
the NSO as expeditiously as practicable but in no case later than the
deadlines contained in this subpart or any other section of these
regulations. For requirements not immediately effective, the NSO shall
provide increments of progress and a schedule for compliance. Each
schedule must reflect the extent to which any required equipment or
systems are already in place and the extent to which any required
reports or studies have already been completed.
