                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1

    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, July 1, 2016), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

PAST PROVISIONS OF THE CODE

    Provisions of the Code that are no longer in force and effect as of 
the revision date stated on the cover of each volume are not carried. 
Code users may find the text of provisions in effect on any given date 
in the past by using the appropriate List of CFR Sections Affected 
(LSA). For the convenience of the reader, a ``List of CFR Sections 
Affected'' is published at the end of each CFR volume. For changes to 
the Code prior to the LSA listings at the end of the volume, consult 
previous annual editions of the LSA. For changes to the Code prior to 
2001, consult the List of CFR Sections Affected compilations, published 
for 1949-1963, 1964-1972, 1973-1985, and 1986-2000.

``[RESERVED]'' TERMINOLOGY

    The term ``[Reserved]'' is used as a place holder within the Code of 
Federal Regulations. An agency may add regulatory information at a 
``[Reserved]'' location at any time. Occasionally ``[Reserved]'' is used 
editorially to indicate that a portion of the CFR was left vacant and 
not accidentally dropped due to a printing or computer error.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed as 
an approved incorporation by reference, please contact the agency that 
issued the regulation containing that incorporation. If, after 
contacting the agency, you find the material is not available, please 
notify the Director of the Federal Register, National Archives and 
Records Administration, 8601 Adelphi Road, College Park, MD 20740-6001, 
or call 202-741-6010.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Authorities 
and Rules. A list of CFR titles, chapters, subchapters, and parts and an 
alphabetical list of agencies publishing in the CFR are also included in 
this volume.

[[Page vii]]

    An index to the text of ``Title 3--The President'' is carried within 
that volume.
    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

REPUBLICATION OF MATERIAL

    There are no restrictions on the republication of material appearing 
in the Code of Federal Regulations.

 Subpart ZZZZ_National Emissions Standards for Hazardous Air Pollutants 
        for Stationary Reciprocating Internal Combustion Engines

    Source: 69 FR 33506, June 15, 2004, unless otherwise noted.

                        What This Subpart Covers



Sec.  63.6580  What is the purpose of subpart ZZZZ?

    Subpart ZZZZ establishes national emission limitations and operating 
limitations for hazardous air pollutants (HAP) emitted from stationary 
reciprocating internal combustion engines (RICE) located at major and 
area sources of HAP emissions. This subpart also establishes 
requirements to demonstrate initial and continuous compliance with the 
emission limitations and operating limitations.

[73 FR 3603, Jan. 18, 2008]



Sec.  63.6585  Am I subject to this subpart?

    You are subject to this subpart if you own or operate a stationary 
RICE at a major or area source of HAP emissions, except if the 
stationary RICE is being tested at a stationary RICE test cell/stand.
    (a) A stationary RICE is any internal combustion engine which uses 
reciprocating motion to convert heat energy into mechanical work and 
which is not mobile. Stationary RICE differ from mobile RICE in that a 
stationary RICE is not a non-road engine as defined at 40 CFR 1068.30, 
and is not used to propel a motor vehicle or a vehicle used solely for 
competition.
    (b) A major source of HAP emissions is a plant site that emits or 
has the potential to emit any single HAP at a rate of 10 tons (9.07 
megagrams) or more per year or any combination of HAP at a rate of 25 
tons (22.68

[[Page 17]]

megagrams) or more per year, except that for oil and gas production 
facilities, a major source of HAP emissions is determined for each 
surface site.
    (c) An area source of HAP emissions is a source that is not a major 
source.
    (d) If you are an owner or operator of an area source subject to 
this subpart, your status as an entity subject to a standard or other 
requirements under this subpart does not subject you to the obligation 
to obtain a permit under 40 CFR part 70 or 71, provided you are not 
required to obtain a permit under 40 CFR 70.3(a) or 40 CFR 71.3(a) for a 
reason other than your status as an area source under this subpart. 
Notwithstanding the previous sentence, you must continue to comply with 
the provisions of this subpart as applicable.
    (e) If you are an owner or operator of a stationary RICE used for 
national security purposes, you may be eligible to request an exemption 
from the requirements of this subpart as described in 40 CFR part 1068, 
subpart C.
    (f) The emergency stationary RICE listed in paragraphs (f)(1) 
through (3) of this section are not subject to this subpart. The 
stationary RICE must meet the definition of an emergency stationary RICE 
in Sec.  63.6675, which includes operating according to the provisions 
specified in Sec.  63.6640(f).
    (1) Existing residential emergency stationary RICE located at an 
area source of HAP emissions that do not operate or are not 
contractually obligated to be available for more than 15 hours per 
calendar year for the purposes specified in Sec.  63.6640(f)(2)(ii) and 
(iii) and that do not operate for the purpose specified in Sec.  
63.6640(f)(4)(ii).
    (2) Existing commercial emergency stationary RICE located at an area 
source of HAP emissions that do not operate or are not contractually 
obligated to be available for more than 15 hours per calendar year for 
the purposes specified in Sec.  63.6640(f)(2)(ii) and (iii) and that do 
not operate for the purpose specified in Sec.  63.6640(f)(4)(ii).
    (3) Existing institutional emergency stationary RICE located at an 
area source of HAP emissions that do not operate or are not 
contractually obligated to be available for more than 15 hours per 
calendar year for the purposes specified in Sec.  63.6640(f)(2)(ii) and 
(iii) and that do not operate for the purpose specified in Sec.  
63.6640(f)(4)(ii).

[69 FR 33506, June 15, 2004, as amended at 73 FR 3603, Jan. 18, 2008; 78 
FR 6700, Jan. 30, 2013]



Sec.  63.6590  What parts of my plant does this subpart cover?

    This subpart applies to each affected source.
    (a) Affected source. An affected source is any existing, new, or 
reconstructed stationary RICE located at a major or area source of HAP 
emissions, excluding stationary RICE being tested at a stationary RICE 
test cell/stand.
    (1) Existing stationary RICE.
    (i) For stationary RICE with a site rating of more than 500 brake 
horsepower (HP) located at a major source of HAP emissions, a stationary 
RICE is existing if you commenced construction or reconstruction of the 
stationary RICE before December 19, 2002.
    (ii) For stationary RICE with a site rating of less than or equal to 
500 brake HP located at a major source of HAP emissions, a stationary 
RICE is existing if you commenced construction or reconstruction of the 
stationary RICE before June 12, 2006.

    (d) You must conduct three separate test runs for each performance 
test required in this section, as specified in Sec.  63.7(e)(3). Each 
test run must last at least 1 hour, unless otherwise specified in this 
subpart.
    (e)(1) You must use Equation 1 of this section to determine 
compliance with the percent reduction requirement:
[GRAPHIC] [TIFF OMITTED] TR30JA13.007


Where:

Ci = concentration of carbon monoxide (CO), total 
          hydrocarbons (THC), or formaldehyde at the control device 
          inlet,

    (2) You must normalize the CO, THC, or formaldehyde concentrations 
at the inlet and outlet of the control device to a dry basis and to 15 
percent oxygen, or an equivalent percent carbon dioxide 
(CO2). If pollutant concentrations are to be corrected to 15 
percent oxygen and CO2 concentration is measured in lieu of 
oxygen concentration measurement, a CO2 correction factor is 
needed. Calculate the CO2 correction factor as described in 
paragraphs (e)(2)(i) through (iii) of this section.
    (i) Calculate the fuel-specific Fo value for the fuel 
burned during the test using values obtained from Method 19, Section 
5.2, and the following equation:
[GRAPHIC] [TIFF OMITTED] TR30JA13.008

Where:

Fo = Fuel factor based on the ratio of oxygen volume to the 
          ultimate CO2 volume produced by the fuel at zero 
          percent excess air.
0.209 = Fraction of air that is oxygen, percent/100.
Fd = Ratio of the volume of dry effluent gas to the gross 
          calorific value of the fuel from Method 19, dsm\3\/J (dscf/
          10\6\ Btu).
Fc = Ratio of the volume of CO2 produced to the 
          gross calorific value of the fuel from Method 19, dsm\3\/J 
          (dscf/10\6\ Btu)

    (ii) Calculate the CO2 correction factor for correcting 
measurement data to 15 percent O2, as follows:

[[Page 26]]

[GRAPHIC] [TIFF OMITTED] TR30JA13.009

Where:

XCO2 = CO2 correction factor, percent.
5.9 = 20.9 percent O2--15 percent O2, the defined 
          O2 correction value, percent.
    (iii) Calculate the CO, THC, and formaldehyde gas concentrations 
adjusted to 15 percent O2 using CO2 as follows:
[GRAPHIC] [TIFF OMITTED] TR30JA13.010

Where:

Cadj = Calculated concentration of CO, THC, or formaldehyde 
          adjusted to 15 percent O2.
Cd = Measured concentration of CO, THC, or formaldehyde, 
          uncorrected.
XCO2 = CO2 correction factor, percent.
%CO2 = Measured CO2 concentration measured, dry 
          basis, percent.

    (f) If you comply with the emission limitation to reduce CO and you 
are not using an oxidation catalyst, if you comply with the emission 
limitation to reduce formaldehyde and you are not using NSCR, or if you 
comply with the emission limitation to limit the concentration of 
formaldehyde in the stationary RICE exhaust and you are not using an 
oxidation catalyst or NSCR, you must petition the Administrator for 
operating limitations to be established during the initial performance 
test and continuously monitored thereafter; or for approval of no 
operating limitations. You must not conduct the initial performance test 
until after the petition has been approved by the Administrator.
    (g) If you petition the Administrator for approval of operating 
limitations, your petition must include the information described in 
paragraphs (g)(1) through (5) of this section.
    (1) Identification of the specific parameters you propose to use as 
operating limitations;
    (2) A discussion of the relationship between these parameters and 
HAP emissions, identifying how HAP emissions change with changes in 
these parameters, and how limitations on these parameters will serve to 
limit HAP emissions;
    (3) A discussion of how you will establish the upper and/or lower 
values for these parameters which will establish the limits on these 
parameters in the operating limitations;
    (4) A discussion identifying the methods you will use to measure and 
the instruments you will use to monitor these parameters, as well as the 
relative accuracy and precision of these methods and instruments; and
    (5) A discussion identifying the frequency and methods for 
recalibrating the instruments you will use for monitoring these 
parameters.
    (h) If you petition the Administrator for approval of no operating 
limitations, your petition must include the information described in 
paragraphs (h)(1) through (7) of this section.
    (1) Identification of the parameters associated with operation of 
the stationary RICE and any emission control device which could change 
intentionally (e.g., operator adjustment, automatic controller 
adjustment, etc.) or unintentionally (e.g., wear and tear, error, etc.) 
on a routine basis or over time;
    (2) A discussion of the relationship, if any, between changes in the 
parameters and changes in HAP emissions;
    (3) For the parameters which could change in such a way as to 
increase HAP emissions, a discussion of whether establishing limitations 
on the parameters would serve to limit HAP emissions;
    (4) For the parameters which could change in such a way as to 
increase HAP emissions, a discussion of how you could establish upper 
and/or lower

[[Page 27]]

values for the parameters which would establish limits on the parameters 
in operating limitations;
    (5) For the parameters, a discussion identifying the methods you 
could use to measure them and the instruments you could use to monitor 
them, as well as the relative accuracy and precision of the methods and 
instruments;
    (6) For the parameters, a discussion identifying the frequency and 
methods for recalibrating the instruments you could use to monitor them; 
and
    (7) A discussion of why, from your point of view, it is infeasible 
or unreasonable to adopt the parameters as operating limitations.
    (i) The engine percent load during a performance test must be 
determined by documenting the calculations, assumptions, and measurement 
devices used to measure or estimate the percent load in a specific 
application. A written report of the average percent load determination 
must be included in the notification of compliance status. The following 
information must be included in the written report: the engine model 
number, the engine manufacturer, the year of purchase, the 
manufacturer's site-rated brake horsepower, the ambient temperature, 
pressure, and humidity during the performance test, and all assumptions 
that were made to estimate or calculate percent load during the 
performance test must be clearly explained. If measurement devices such 
as flow meters, kilowatt meters, beta analyzers, stain gauges, etc. are 
used, the model number of the measurement device, and an estimate of its 
accurate in percentage of true value must be provided.

the work, operation or management practices in items 1 or 2 of Table 2c 
to this subpart or in items 1 or 4 of Table 2d to this subpart, you have 
the option of utilizing an oil analysis program in order to extend the 
specified oil change requirement in Tables 2c and 2d to this subpart. 
The oil analysis must be performed at the same frequency specified for 
changing the oil in Table 2c or 2d to this subpart. The analysis program 
must at a minimum analyze the following three parameters: Total Base 
Number, viscosity, and percent water content. The condemning limits for 
these parameters are as follows: Total Base Number is less than 30 
percent of the Total Base Number of the oil when new; viscosity of the 
oil has changed by more than 20 percent from the viscosity of the oil 
when new; or percent water content (by volume) is greater than 0.5. If 
all of these condemning limits are not exceeded, the engine owner or 
operator is not required to change the oil. If any of the limits are 
exceeded, the engine owner or operator must change the oil within 2 
business days of receiving the results of the analysis; if the engine is 
not in operation when the results of the analysis are received, the 
engine owner or operator must change the oil within 2 business days or 
before commencing operation, whichever is later. The owner or operator 
must keep records of the parameters that are analyzed as part of the 
program, the results of the analysis, and the oil changes for the 
engine. The analysis program must be part of the maintenance plan for 
the engine.

subpart, you have the option of utilizing an oil analysis program in 
order to extend the specified oil change requirement in Tables 2c and 2d 
to this subpart. The oil analysis must be performed at the same 
frequency specified for changing the oil in Table 2c or 2d to this 
subpart. The analysis program must at a minimum analyze the following 
three parameters: Total Acid Number, viscosity, and percent water

[[Page 30]]

content. The condemning limits for these parameters are as follows: 
Total Acid Number increases by more than 3.0 milligrams of potassium 
hydroxide (KOH) per gram from Total Acid Number of the oil when new; 
viscosity of the oil has changed by more than 20 percent from the 
viscosity of the oil when new; or percent water content (by volume) is 
greater than 0.5. If all of these condemning limits are not exceeded, 
the engine owner or operator is not required to change the oil. If any 
of the limits are exceeded, the engine owner or operator must change the 
oil within 2 business days of receiving the results of the analysis; if 
the engine is not in operation when the results of the analysis are 
received, the engine owner or operator must change the oil within 2 
business days or before commencing operation, whichever is later. The 
owner or operator must keep records of the parameters that are analyzed 
as part of the program, the results of the analysis, and the oil changes 
for the engine. The analysis program must be part of the maintenance 
plan for the engine.

                   Continuous Compliance Requirements



Sec.  63.6635  How do I monitor and collect data to demonstrate
continuous compliance?

    (a) If you must comply with emission and operating limitations, you 
must monitor and collect data according to this section.
    (b) Except for monitor malfunctions, associated repairs, required 
performance evaluations, and required quality assurance or control 
activities, you must monitor continuously at all times that the 
stationary RICE is operating. A monitoring malfunction is any sudden, 
infrequent, not reasonably preventable failure of the monitoring to 
provide valid data. Monitoring failures that are caused in part by poor 
maintenance or careless operation are not malfunctions.
    (c) You may not use data recorded during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
in data averages and calculations used to report emission or operating 
levels. You must, however, use all the valid data collected during all 
other periods.

[69 FR 33506, June 15, 2004, as amended at 76 FR 12867, Mar. 9, 2011]



Sec.  63.6640  How do I demonstrate continuous compliance with the 
emission limitations, operating limitations, and other requirements?

    (a) You must demonstrate continuous compliance with each emission 
limitation, operating limitation, and other requirements in Tables 1a 
and 1b, Tables 2a and 2b, Table 2c, and Table 2d to this subpart that 
apply to you according to methods specified in Table 6 to this subpart.
    (b) You must report each instance in which you did not meet each 
emission limitation or operating limitation in Tables 1a and 1b, Tables 
2a and 2b, Table 2c, and Table 2d to this subpart that apply to you. 
These instances are deviations from the emission and operating 
limitations in this subpart. These deviations must be reported according 
to the requirements in Sec.  63.6650. If you change your catalyst, you 
must reestablish the values of the operating parameters measured during 
the initial performance test. When you reestablish the values of your 
operating parameters, you must also conduct a performance test to 
demonstrate that you are meeting the required emission limitation 
applicable to your stationary RICE.
    (c) The annual compliance demonstration required for existing non-
emergency 4SLB and 4SRB stationary RICE with a site rating of more than 
500 HP located at an area source of HAP that are not remote stationary 
RICE and that are operated more than 24 hours per calendar year must be 
conducted according to the following requirements:
    (1) The compliance demonstration must consist of at least one test 
run.
    (2) Each test run must be of at least 15 minute duration, except 
that each test conducted using the method in appendix A to this subpart 
must consist of at least one measurement cycle and include at least 2 
minutes of test data phase measurement.
    (3) If you are demonstrating compliance with the CO concentration or 
CO percent reduction requirement, you must measure CO emissions using 
one of the CO measurement methods specified in Table 4 of this subpart, 
or using appendix A to this subpart.
    (4) If you are demonstrating compliance with the THC percent 
reduction requirement, you must measure THC emissions using Method 25A, 
reported as propane, of 40 CFR part 60, appendix A.
    (5) You must measure O2 using one of the O2 
measurement methods specified in Table 4 of this subpart. Measurements 
to determine O2 concentration must be made at the same time 
as the measurements for CO or THC concentration.
    (6) If you are demonstrating compliance with the CO or THC percent 
reduction requirement, you must measure CO or THC emissions and 
O2 emissions simultaneously at the inlet and outlet of the 
control device.
    (7) If the results of the annual compliance demonstration show that 
the emissions exceed the levels specified in Table 6 of this subpart, 
the stationary RICE must be shut down as soon as safely possible, and 
appropriate corrective action must be taken (e.g., repairs,

[[Page 32]]

catalyst cleaning, catalyst replacement). The stationary RICE must be 
retested within 7 days of being restarted and the emissions must meet 
the levels specified in Table 6 of this subpart. If the retest shows 
that the emissions continue to exceed the specified levels, the 
stationary RICE must again be shut down as soon as safely possible, and 
the stationary RICE may not operate, except for purposes of startup and 
testing, until the owner/operator demonstrates through testing that the 
emissions do not exceed the levels specified in Table 6 of this subpart.
    (d) For new, reconstructed, and rebuilt stationary RICE, deviations 
from the emission or operating limitations that occur during the first 
200 hours of operation from engine startup (engine burn-in period) are 
not violations. Rebuilt stationary RICE means a stationary RICE that has 
been rebuilt as that term is defined in 40 CFR 94.11(a).
    (e) You must also report each instance in which you did not meet the 
requirements in Table 8 to this subpart that apply to you. If you own or 
operate a new or reconstructed stationary RICE with a site rating of 
less than or equal to 500 brake HP located at a major source of HAP 
emissions (except new or reconstructed 4SLB engines greater than or 
equal to 250 and less than or equal to 500 brake HP), a new or 
reconstructed stationary RICE located at an area source of HAP 
emissions, or any of the following RICE with a site rating of more than 
500 brake HP located at a major source of HAP emissions, you do not need 
to comply with the requirements in Table 8 to this subpart: An existing 
2SLB stationary RICE, an existing 4SLB stationary RICE, an existing 
emergency stationary RICE, an existing limited use stationary RICE, or 
an existing stationary RICE which fires landfill gas or digester gas 
equivalent to 10 percent or more of the gross heat input on an annual 
basis. If you own or operate any of the following RICE with a site 
rating of more than 500 brake HP located at a major source of HAP 
emissions, you do not need to comply with the requirements in Table 8 to 
this subpart, except for the initial notification requirements: a new or 
reconstructed stationary RICE that combusts landfill gas or digester gas 
equivalent to 10 percent or more of the gross heat input on an annual 
basis, a new or reconstructed emergency stationary RICE, or a new or 
reconstructed limited use stationary RICE.
    (f) If you own or operate an emergency stationary RICE, you must 
operate the emergency stationary RICE according to the requirements in 
paragraphs (f)(1) through (4) of this section. In order for the engine 
to be considered an emergency stationary RICE under this subpart, any 
operation other than emergency operation, maintenance and testing, 
emergency demand response, and operation in non-emergency situations for 
50 hours per year, as described in paragraphs (f)(1) through (4) of this 
section, is prohibited. If you do not operate the engine according to 
the requirements in paragraphs (f)(1) through (4) of this section, the 
engine will not be considered an emergency engine under this subpart and 
must meet all requirements for non-emergency engines.
    (1) There is no time limit on the use of emergency stationary RICE 
in emergency situations.
    (2) You may operate your emergency stationary RICE for any 
combination of the purposes specified in paragraphs (f)(2)(i) through 
(iii) of this section for a maximum of 100 hours per calendar year. Any 
operation for non-emergency situations as allowed by paragraphs (f)(3) 
and (4) of this section counts as part of the 100 hours per calendar 
year allowed by this paragraph (f)(2).
    (i) Emergency stationary RICE may be operated for maintenance checks 
and readiness testing, provided that the tests are recommended by 
federal, state or local government, the manufacturer, the vendor, the 
regional transmission organization or equivalent balancing authority and 
transmission operator, or the insurance company associated with the 
engine. The owner or operator may petition the Administrator for 
approval of additional hours to be used for maintenance checks and 
readiness testing, but a petition is not required if the owner or 
operator maintains records indicating that federal, state, or local 
standards require maintenance and

[[Page 33]]

testing of emergency RICE beyond 100 hours per calendar year.
    (ii) Emergency stationary RICE may be operated for emergency demand 
response for periods in which the Reliability Coordinator under the 
North American Electric Reliability Corporation (NERC) Reliability 
Standard EOP-002-3, Capacity and Energy Emergencies (incorporated by 
reference, see Sec.  63.14), or other authorized entity as determined by 
the Reliability Coordinator, has declared an Energy Emergency Alert 
Level 2 as defined in the NERC Reliability Standard EOP-002-3.
    (iii) Emergency stationary RICE may be operated for periods where 
there is a deviation of voltage or frequency of 5 percent or greater 
below standard voltage or frequency.
    (3) Emergency stationary RICE located at major sources of HAP may be 
operated for up to 50 hours per calendar year in non-emergency 
situations. The 50 hours of operation in non-emergency situations are 
counted as part of the 100 hours per calendar year for maintenance and 
testing and emergency demand response provided in paragraph (f)(2) of 
this section. The 50 hours per year for non-emergency situations cannot 
be used for peak shaving or non-emergency demand response, or to 
generate income for a facility to supply power to an electric grid or 
otherwise supply power as part of a financial arrangement with another 
entity.
    (4) Emergency stationary RICE located at area sources of HAP may be 
operated for up to 50 hours per calendar year in non-emergency 
situations. The 50 hours of operation in non-emergency situations are 
counted as part of the 100 hours per calendar year for maintenance and 
testing and emergency demand response provided in paragraph (f)(2) of 
this section. Except as provided in paragraphs (f)(4)(i) and (ii) of 
this section, the 50 hours per year for non-emergency situations cannot 
be used for peak shaving or non-emergency demand response, or to 
generate income for a facility to an electric grid or otherwise supply 
power as part of a financial arrangement with another entity.
    (i) Prior to May 3, 2014, the 50 hours per year for non-emergency 
situations can be used for peak shaving or non-emergency demand response 
to generate income for a facility, or to otherwise supply power as part 
of a financial arrangement with another entity if the engine is operated 
as part of a peak shaving (load management program) with the local 
distribution system operator and the power is provided only to the 
facility itself or to support the local distribution system.
    (ii) The 50 hours per year for non-emergency situations can be used 
to supply power as part of a financial arrangement with another entity 
if all of the following conditions are met:
    (A) The engine is dispatched by the local balancing authority or 
local transmission and distribution system operator.
    (B) The dispatch is intended to mitigate local transmission and/or 
distribution limitations so as to avert potential voltage collapse or 
line overloads that could lead to the interruption of power supply in a 
local area or region.
    (C) The dispatch follows reliability, emergency operation or similar 
protocols that follow specific NERC, regional, state, public utility 
commission or local standards or guidelines.
    (D) The power is provided only to the facility itself or to support 
the local transmission and distribution system.
    (E) The owner or operator identifies and records the entity that 
dispatches the engine and the specific NERC, regional, state, public 
utility commission or local standards or guidelines that are being 
followed for dispatching the engine. The local balancing authority or 
local transmission and distribution system operator may keep these 
records on behalf of the engine owner or operator.

    Glycol dehydration unit means a device in which a liquid glycol 
(including, but not limited to, ethylene glycol, diethylene glycol, or 
triethylene glycol) absorbent directly contacts a natural gas stream and 
absorbs water in a contact tower or absorption column (absorber). The 
glycol contacts and absorbs water vapor and other gas stream 
constituents from the natural gas and becomes ``rich'' glycol. This 
glycol is then regenerated in the glycol dehydration unit reboiler. The 
``lean'' glycol is then recycled.

be aggregated with emissions from other similar units, to determine 
whether such emission points or stations are major sources, even when 
emission points are in a contiguous area or under common control;
    (2) For oil and gas production facilities, emissions from processes, 
operations, or equipment that are not part of the same oil and gas

    Oil and gas production facility as used in this subpart means any 
grouping of equipment where hydrocarbon liquids are processed, upgraded 
(i.e., remove impurities or other constituents to meet contract 
specifications), or stored prior to the point of custody transfer; or 
where natural gas is processed, upgraded, or stored prior to entering 
the natural gas transmission and storage source category. For purposes 
of a major source determination, facility (including a building, 
structure, or installation) means oil and natural gas production and 
processing equipment that is located within the boundaries of an 
individual surface site as defined in this section. Equipment that is 
part of a facility will typically be located within close proximity to

    Potential to emit means the maximum capacity of a stationary source 
to emit a pollutant under its physical and operational design. Any 
physical or operational limitation on the capacity of the stationary 
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 part of 
its design if the limitation or the effect it would have on emissions is 
federally enforceable. For oil and natural gas production facilities 
subject to subpart HH of this part, the potential to emit provisions in 
Sec.  63.760(a) may be used. For natural gas transmission and storage 
facilities subject to subpart HHH of this part, the maximum annual 
facility gas throughput for storage facilities may be determined 
according to Sec.  63.1270(a)(1) and the maximum annual throughput for

occupancy and no buildings with four or more stories within 220 yards 
(200 meters) on either side of the centerline of any continuous 1-mile 
(1.6 kilometers) length of pipeline. Each separate dwelling unit in a 
multiple dwelling unit building is counted as a separate building 
intended for human occupancy.
    (ii) The pipeline segment does not lie within 100 yards (91 meters) 
of either a building or a small, well-defined outside area (such as a 
playground, recreation area, outdoor theater, or other place of public 
assembly) that is occupied by 20 or more persons on at least 5 days a 
week for 10 weeks in any 12-month period. The days and weeks need not be 
consecutive. The building or area is considered occupied for a full day 
if it is occupied for any portion of the day.
    (iii) For purposes of this paragraph (2), the term pipeline segment 
means all parts of those physical facilities through which gas moves in 
transportation, including but not limited to pipe, valves, and other 
appurtenance attached to pipe, compressor units, metering stations, 
regulator stations, delivery stations, holders, and fabricated 
assemblies. Stationary RICE located within 50 yards (46 meters) of the 
pipeline segment providing power for equipment on a pipeline segment are 
part of the pipeline segment. Transportation of gas means the gathering,

the manufacturer's recommended operating air/fuel ratio divided by the 
stoichiometric air/fuel ratio at full load conditions is less than or 
equal to 1.1. Engines originally manufactured as rich burn engines, but 
modified prior to December 19, 2002 with passive emission control 
technology for NOX (such as pre-combustion chambers) will be 
considered lean burn engines. Also, existing engines where there are no 
manufacturer's recommendations regarding air/fuel ratio will be 
considered a rich burn engine if the excess oxygen content of the 
exhaust at full load conditions is less than or equal to 2 percent.
    Site-rated HP means the maximum manufacturer's design capacity at 
engine site conditions.
    Spark ignition means relating to either: A gasoline-fueled engine;

theoretical Otto combustion cycle. Spark ignition engines usually use a 
throttle to regulate intake air flow to control power during normal 
operation. Dual-fuel engines in which a liquid fuel (typically diesel 
fuel) is used for CI and gaseous fuel (typically natural gas) is used as 
the primary fuel at an annual average ratio of less than 2 parts diesel

storage vessel that contains a hydrocarbon liquid with a stock tank gas-
to-oil ratio equal to or greater than 0.31 cubic meters per liter and an 
American Petroleum Institute gravity equal to or greater than 40 degrees 
and an actual annual average hydrocarbon liquid throughput equal to or 
greater than 79,500 liters per day. Flash emissions occur when dissolved 
hydrocarbons in the fluid evolve from solution when the fluid pressure 
is reduced.
    Subpart means 40 CFR part 63, subpart ZZZZ.
    Surface site means any combination of one or more graded pad sites, 
gravel pad sites, foundations, platforms, or the immediate physical 
location upon which equipment is physically affixed.
    Two-stroke engine means a type of engine which completes the power 
cycle in single crankshaft revolution by combining the intake and 
compression operations into one stroke and the power and exhaust 
operations into a second stroke. This system requires auxiliary 
scavenging and inherently runs lean of stoichiometric.

\1\ Sources have the option to utilize an oil analysis program as
  described in Sec.   63.6625(i) or (j) in order to extend the specified
  oil change requirement in Table 2d of this subpart.
\2\ If an emergency engine is operating during an emergency and it is
  not possible to shut down the engine in order to perform the
  management practice requirements on the schedule required in Table 2d
  of this subpart, or if performing the management practice on the
  required schedule would otherwise pose an unacceptable risk under
  federal, state, or local law, the management practice can be delayed
  until the emergency is over or the unacceptable risk under federal,
  state, or local law has abated. The management practice should be
  performed as soon as practicable after the emergency has ended or the
  unacceptable risk under federal, state, or local law has abated.
  Sources must report any failure to perform the management practice on
  the schedule required and the federal, state or local law under which
  the risk was deemed unacceptable.

\a\ After you have demonstrated compliance for two consecutive tests,
  you may reduce the frequency of subsequent performance tests to
  annually. If the results of any subsequent annual performance test
  indicate the stationary RICE is not in compliance with the CO or
  formaldehyde emission limitation, or you deviate from any of your
  operating limitations, you must resume semiannual performance tests.

   Sec. Appendix A to Subpart ZZZZ of Part 63--Protocol for Using an 
    Electrochemical Analyzer to Determine Oxygen and Carbon Monoxide 
                   Concentrations From Certain Engines

            1.0 Scope and Application. What is this Protocol?

    This protocol is a procedure for using portable electrochemical (EC) 
cells for measuring carbon monoxide (CO) and oxygen (O2) 
concentrations in controlled and uncontrolled emissions from existing 
stationary 4-stroke lean burn and 4-stroke rich burn reciprocating 
internal combustion engines as specified in the applicable rule.

            1.1 Analytes. What does this protocol determine?

    This protocol measures the engine exhaust gas concentrations of 
carbon monoxide (CO) and oxygen (O2).

------------------------------------------------------------------------

                                                  whichever is less
                                                  restrictive.
Oxygen (O2)....................       7782-44-7
------------------------------------------------------------------------

          1.2 Applicability. When is this protocol acceptable?

    This protocol is applicable to 40 CFR part 63, subpart ZZZZ. Because 
of inherent cross sensitivities of EC cells, you must not apply this 
protocol to other emissions sources without specific instruction to that 
effect.

    1.3 Data Quality Objectives. How good must my collected data be?

    Refer to Section 13 to verify and document acceptable analyzer 
performance.

   1.4 Range. What is the targeted analytical range for this protocol?

    The measurement system and EC cell design(s) conforming to this 
protocol will determine the analytical range for each gas component. The 
nominal ranges are defined by choosing up-scale calibration gas 
concentrations near the maximum anticipated flue gas concentrations for 
CO and O2, or no more than twice the permitted CO level.

1.5 Sensitivity. What minimum detectable limit will this protocol yield 
                     for a particular gas component?

    The minimum detectable limit depends on the nominal range and 
resolution of the specific EC cell used, and the signal to noise ratio 
of the measurement system. The minimum detectable limit should be 2 
percent of the nominal range or 1 ppm, whichever is less restrictive.

                         2.0 Summary of Protocol

    In this protocol, a gas sample is extracted from an engine exhaust 
system and then conveyed to a portable EC analyzer for measurement of CO 
and O2 gas concentrations. This method provides measurement 
system performance specifications and sampling protocols to ensure 
reliable data. You may use additions to, or modifications of vendor 
supplied measurement systems (e.g., heated or unheated sample lines, 
thermocouples, flow meters, selective gas scrubbers, etc.) to meet the 
design specifications of this protocol. Do not make changes to the 
measurement system from the as-verified configuration (Section 3.12).

                             3.0 Definitions

    3.1 Measurement System. The total equipment required for the 
measurement of CO and O2 concentrations. The measurement 
system consists of the following major subsystems:
    3.1.1 Data Recorder. A strip chart recorder, computer or digital 
recorder for logging measurement data from the analyzer output. You may 
record measurement data from the digital data display manually or 
electronically.
    3.1.2 Electrochemical (EC) Cell. A device, similar to a fuel cell, 
used to sense the presence of a specific analyte and generate an 
electrical current output proportional to the analyte concentration.
    3.1.3 Interference Gas Scrubber. A device used to remove or 
neutralize chemical compounds that may interfere with the selective 
operation of an EC cell.
    3.1.4 Moisture Removal System. Any device used to reduce the 
concentration of moisture in the sample stream so as to protect the EC 
cells from the damaging effects of condensation and to minimize errors 
in measurements caused by the scrubbing of soluble gases.
    3.1.5 Sample Interface. The portion of the system used for one or 
more of the following: sample acquisition; sample transport; sample 
conditioning or protection of the EC cell from any degrading effects of 
the engine exhaust effluent; removal of particulate matter and condensed 
moisture.
    3.2 Nominal Range. The range of analyte concentrations over which 
each EC cell is operated (normally 25 percent to 150 percent of up-scale 
calibration gas value). Several

[[Page 65]]

nominal ranges can be used for any given cell so long as the calibration 
and repeatability checks for that range remain within specifications.
    3.3 Calibration Gas. A vendor certified concentration of a specific 
analyte in an appropriate balance gas.
    3.4 Zero Calibration Error. The analyte concentration output 
exhibited by the EC cell in response to zero-level calibration gas.
    3.5 Up-Scale Calibration Error. The mean of the difference between 
the analyte concentration exhibited by the EC cell and the certified 
concentration of the up-scale calibration gas.
    3.6 Interference Check. A procedure for quantifying analytical 
interference from components in the engine exhaust gas other than the 
targeted analytes.
    3.7 Repeatability Check. A protocol for demonstrating that an EC 
cell operated over a given nominal analyte concentration range provides 
a stable and consistent response and is not significantly affected by 
repeated exposure to that gas.
    3.8 Sample Flow Rate. The flow rate of the gas sample as it passes 
through the EC cell. In some situations, EC cells can experience drift 
with changes in flow rate. The flow rate must be monitored and 
documented during all phases of a sampling run.
    3.9 Sampling Run. A timed three-phase event whereby an EC cell's 
response rises and plateaus in a sample conditioning phase, remains 
relatively constant during a measurement data phase, then declines 
during a refresh phase. The sample conditioning phase exposes the EC 
cell to the gas sample for a length of time sufficient to reach a 
constant response. The measurement data phase is the time interval 
during which gas sample measurements can be made that meet the 
acceptance criteria of this protocol. The refresh phase then purges the 
EC cells with CO-free air. The refresh phase replenishes requisite 
O2 and moisture in the electrolyte reserve and provides a 
mechanism to de-gas or desorb any interference gas scrubbers or filters 
so as to enable a stable CO EC cell response. There are four primary 
types of sampling runs: pre- sampling calibrations; stack gas sampling; 
post-sampling calibration checks; and measurement system repeatability 
checks. Stack gas sampling runs can be chained together for extended 
evaluations, providing all other procedural specifications are met.
    3.10 Sampling Day. A time not to exceed twelve hours from the time 
of the pre-sampling calibration to the post-sampling calibration check. 
During this time, stack gas sampling runs can be repeated without 
repeated recalibrations, providing all other sampling specifications 
have been met.
    3.11 Pre-Sampling Calibration/Post-Sampling Calibration Check. The 
protocols executed at the beginning and end of each sampling day to 
bracket measurement readings with controlled performance checks.
    3.12 Performance-Established Configuration. The EC cell and sampling 
system configuration that existed at the time that it initially met the 
performance requirements of this protocol.

                           4.0 Interferences.

    When present in sufficient concentrations, NO and NO2 are 
two gas species that have been reported to interfere with CO 
concentration measurements. In the likelihood of this occurrence, it is 
the protocol user's responsibility to employ and properly maintain an 
appropriate CO EC cell filter or scrubber for removal of these gases, as 
described in Section 6.2.12.

                         5.0 Safety. [Reserved]

                       6.0 Equipment and Supplies.

        6.1 What equipment do I need for the measurement system?

    The system must maintain the gas sample at conditions that will 
prevent moisture condensation in the sample transport lines, both before 
and as the sample gas contacts the EC cells. The essential components of 
the measurement system are described below.

                   6.2 Measurement System Components.

    6.2.1 Sample Probe. A single extraction-point probe constructed of 
glass, stainless steel or other non-reactive material, and of length 
sufficient to reach any designated sampling point. The sample probe must 
be designed to prevent plugging due to condensation or particulate 
matter.
    6.2.2 Sample Line. Non-reactive tubing to transport the effluent 
from the sample probe to the EC cell.
    6.2.3 Calibration Assembly (optional). A three-way valve assembly or 
equivalent to introduce calibration gases at ambient pressure at the 
exit end of the sample probe during calibration checks. The assembly 
must be designed such that only stack gas or calibration gas flows in 
the sample line and all gases flow through any gas path filters.
    6.2.4 Particulate Filter (optional). Filters before the inlet of the 
EC cell to prevent accumulation of particulate material in the 
measurement system and extend the useful life of the components. All 
filters must be fabricated of materials that are non-reactive to the gas 
mixtures being sampled.
    6.2.5 Sample Pump. A leak-free pump to provide undiluted sample gas 
to the system at a flow rate sufficient to minimize the response time of 
the measurement system. If located upstream of the EC cells, the pump 
must be constructed of a material that is non-reactive to the gas 
mixtures being sampled.
    6.2.8 Sample Flow Rate Monitoring. An adjustable rotameter or 
equivalent device used

[[Page 66]]

to adjust and maintain the sample flow rate through the analyzer as 
prescribed.
    6.2.9 Sample Gas Manifold (optional). A manifold to divert a portion 
of the sample gas stream to the analyzer and the remainder to a by-pass 
discharge vent. The sample gas manifold may also include provisions for 
introducing calibration gases directly to the analyzer. The manifold 
must be constructed of a material that is non-reactive to the gas 
mixtures being sampled.
    6.2.10 EC cell. A device containing one or more EC cells to 
determine the CO and O2 concentrations in the sample gas 
stream. The EC cell(s) must meet the applicable performance 
specifications of Section 13 of this protocol.
    6.2.11 Data Recorder. A strip chart recorder, computer or digital 
recorder to make a record of analyzer output data. The data recorder 
resolution (i.e., readability) must be no greater than 1 ppm for CO; 0.1 
percent for O2; and one degree (either [deg]C or [deg]F) for 
temperature. Alternatively, you may use a digital or analog meter having 
the same resolution to observe and manually record the analyzer 
responses.
    6.2.12 Interference Gas Filter or Scrubber. A device to remove 
interfering compounds upstream of the CO EC cell. Specific interference 
gas filters or scrubbers used in the performance-established 
configuration of the analyzer must continue to be used. Such a filter or 
scrubber must have a means to determine when the removal agent is 
exhausted. Periodically replace or replenish it in accordance with the 
manufacturer's recommendations.

     7.0 Reagents and Standards. What calibration gases are needed?

    7.1 Calibration Gases. CO calibration gases for the EC cell must be 
CO in nitrogen or CO in a mixture of nitrogen and O2. Use CO 
calibration gases with labeled concentration values certified by the 
manufacturer to be within 5 percent of the label 
value. Dry ambient air (20.9 percent O2) is acceptable for 
calibration of the O2 cell. If needed, any lower percentage 
O2 calibration gas must be a mixture of O2 in 
nitrogen.
    7.1.1 Up-Scale CO Calibration Gas Concentration. Choose one or more 
up-scale gas concentrations such that the average of the stack gas 
measurements for each stack gas sampling run are between 25 and 150 
percent of those concentrations. Alternatively, choose an up-scale gas 
that does not exceed twice the concentration of the applicable outlet 
standard. If a measured gas value exceeds 150 percent of the up-scale CO 
calibration gas value at any time during the stack gas sampling run, the 
run must be discarded and repeated.
    7.1.2 Up-Scale O2 Calibration Gas Concentration.
    Select an O2 gas concentration such that the difference 
between the gas concentration and the average stack gas measurement or 
reading for each sample run is less than 15 percent O2. When 
the average exhaust gas O2 readings are above 6 percent, you 
may use dry ambient air (20.9 percent O2) for the up-scale 
O2 calibration gas.
    7.1.3 Zero Gas. Use an inert gas that contains less than 0.25 
percent of the up-scale CO calibration gas concentration. You may use 
dry air that is free from ambient CO and other combustion gas products 
(e.g., CO2).

                   8.0 Sample Collection and Analysis

    8.1 Selection of Sampling Sites.
    8.1.1 Control Device Inlet. Select a sampling site sufficiently 
downstream of the engine so that the combustion gases should be well 
mixed. Use a single sampling extraction point near the center of the 
duct (e.g., within the 10 percent centroidal area), unless instructed 
otherwise.
    8.1.2 Exhaust Gas Outlet. Select a sampling site located at least 
two stack diameters downstream of any disturbance (e.g., turbocharger 
exhaust, crossover junction or recirculation take-off) and at least one-
half stack diameter upstream of the gas discharge to the atmosphere. Use 
a single sampling extraction point near the center of the duct (e.g., 
within the 10 percent centroidal area), unless instructed otherwise.
    8.2 Stack Gas Collection and Analysis. Prior to the first stack gas 
sampling run, conduct that the pre-sampling calibration in accordance 
with Section 10.1. Use Figure 1 to record all data. Zero the analyzer 
with zero gas. Confirm and record that the scrubber media color is 
correct and not exhausted. Then position the probe at the sampling point 
and begin the sampling run at the same flow rate used during the up-
scale calibration. Record the start time. Record all EC cell output 
responses and the flow rate during the ``sample conditioning phase'' 
once per minute until constant readings are obtained. Then begin the 
``measurement data phase'' and record readings every 15 seconds for at 
least two minutes (or eight readings), or as otherwise required to 
achieve two continuous minutes of data that meet the specification given 
in Section 13.1. Finally, perform the ``refresh phase'' by introducing 
dry air, free from CO and other combustion gases, until several minute-
to-minute readings of consistent value have been obtained. For each run 
use the ``measurement data phase'' readings to calculate the average 
stack gas CO and O2 concentrations.
    8.3 EC Cell Rate. Maintain the EC cell sample flow rate so that it 
does not vary by more than 10 percent throughout 
the pre-sampling calibration, stack gas sampling and post-sampling 
calibration check. Alternatively, the EC cell sample flow rate can be 
maintained within a tolerance range that

[[Page 67]]

does not affect the gas concentration readings by more than 3 percent, as instructed by the EC cell manufacturer.

                     9.0 Quality Control (Reserved)

                  10.0 Calibration and Standardization

    10.1 Pre-Sampling Calibration. Conduct the following protocol once 
for each nominal range to be used on each EC cell before performing a 
stack gas sampling run on each field sampling day. Repeat the 
calibration if you replace an EC cell before completing all of the 
sampling runs. There is no prescribed order for calibration of the EC 
cells; however, each cell must complete the measurement data phase 
during calibration. Assemble the measurement system by following the 
manufacturer's recommended protocols including for preparing and 
preconditioning the EC cell. Assure the measurement system has no leaks 
and verify the gas scrubbing agent is not depleted. Use Figure 1 to 
record all data.
    10.1.1 Zero Calibration. For both the O2 and CO cells, 
introduce zero gas to the measurement system (e.g., at the calibration 
assembly) and record the concentration reading every minute until 
readings are constant for at least two consecutive minutes. Include the 
time and sample flow rate. Repeat the steps in this section at least 
once to verify the zero calibration for each component gas.
    10.1.2 Zero Calibration Tolerance. For each zero gas introduction, 
the zero level output must be less than or equal to 3 percent of the up-scale gas value or 1 ppm, whichever is less restrictive, for the CO channel 
and less than or equal to 0.3 percent 
O2 for the O2 channel.
    10.1.3 Up-Scale Calibration. Individually introduce each calibration 
gas to the measurement system (e.g., at the calibration assembly) and 
record the start time. Record all EC cell output responses and the flow 
rate during this ``sample conditioning phase'' once per minute until 
readings are constant for at least two minutes. Then begin the 
``measurement data phase'' and record readings every 15 seconds for a 
total of two minutes, or as otherwise required. Finally, perform the 
``refresh phase'' by introducing dry air, free from CO and other 
combustion gases, until readings are constant for at least two 
consecutive minutes. Then repeat the steps in this section at least once 
to verify the calibration for each component gas. Introduce all gases to 
flow through the entire sample handling system (i.e., at the exit end of 
the sampling probe or the calibration assembly).
    10.1.4 Up-Scale Calibration Error. The mean of the difference of the 
``measurement data phase'' readings from the reported standard gas value 
must be less than or equal to 5 percent or 1 ppm for CO or 0.5 percent 
O2, whichever is less restrictive, respectively. The maximum 
allowable deviation from the mean measured value of any single 
``measurement data phase'' reading must be less than or equal to 2 percent or 1 ppm for CO or 
0.5 percent O2, whichever is less 
restrictive, respectively.
    10.2 Post-Sampling Calibration Check. Conduct a stack gas post-
sampling calibration check after the stack gas sampling run or set of 
runs and within 12 hours of the initial calibration. Conduct up-scale 
and zero calibration checks using the protocol in Section 10.1. Make no 
changes to the sampling system or EC cell calibration until all post-
sampling calibration checks have been recorded. If either the zero or 
up-scale calibration error exceeds the respective specification in 
Sections 10.1.2 and 10.1.4 then all measurement data collected since the 
previous successful calibrations are invalid and re-calibration and re-
sampling are required. If the sampling system is disassembled or the EC 
cell calibration is adjusted, repeat the calibration check before 
conducting the next analyzer sampling run.

                        11.0 Analytical Procedure

    The analytical procedure is fully discussed in Section 8.

                   12.0 Calculations and Data Analysis

    Determine the CO and O2 concentrations for each stack gas 
sampling run by calculating the mean gas concentrations of the data 
recorded during the ``measurement data phase''.

                        13.0 Protocol Performance

    Use the following protocols to verify consistent analyzer 
performance during each field sampling day.
    13.1 Measurement Data Phase Performance Check. Calculate the mean of 
the readings from the ``measurement data phase''. The maximum allowable 
deviation from the mean for each of the individual readings is 2 percent, or 1 ppm, whichever is 
less restrictive. Record the mean value and maximum deviation for each 
gas monitored. Data must conform to Section 10.1.4. The EC cell flow 
rate must conform to the specification in Section 8.3.

    Example: A measurement data phase is invalid if the maximum 
deviation of any single reading comprising that mean is greater than 
2 percent or 1 ppm (the 
default criteria). For example, if the mean = 30 ppm, single readings of 
below 29 ppm and above 31 ppm are disallowed).

    13.2 Interference Check. Before the initial use of the EC cell and 
interference gas scrubber in the field, and semi-annually thereafter, 
challenge the interference gas scrubber with NO and NO2 gas 
standards that are

[[Page 68]]

generally recognized as representative of diesel-fueled engine NO and 
NO2 emission values. Record the responses displayed by the CO 
EC cell and other pertinent data on Figure 1 or a similar form.
    13.2.1 Interference Response. The combined NO and NO2 
interference response should be less than or equal to 5 percent of the up-scale CO calibration gas 
concentration.
    13.3 Repeatability Check. Conduct the following check once for each 
nominal range that is to be used on the CO EC cell within 5 days prior 
to each field sampling program. If a field sampling program lasts longer 
than 5 days, repeat this check every 5 days. Immediately repeat the 
check if the EC cell is replaced or if the EC cell is exposed to gas 
concentrations greater than 150 percent of the highest up-scale gas 
concentration.
    13.3.1 Repeatability Check Procedure. Perform a complete EC cell 
sampling run (all three phases) by introducing the CO calibration gas to 
the measurement system and record the response. Follow Section 10.1.3. 
Use Figure 1 to record all data. Repeat the run three times for a total 
of four complete runs. During the four repeatability check runs, do not 
adjust the system except where necessary to achieve the correct 
calibration gas flow rate at the analyzer.
    13.3.2 Repeatability Check Calculations. Determine the highest and 
lowest average ``measurement data phase'' CO concentrations from the 
four repeatability check runs and record the results on Figure 1 or a 
similar form. The absolute value of the difference between the maximum 
and minimum average values recorded must not vary more than 3 percent or 1 ppm of the up-scale 
gas value, whichever is less restrictive.

    (c) You may not conduct performance tests during periods of startup, 
shutdown, or malfunction, as specified in Sec.  63.7(e)(1).
    (d) Except for opacity and VE observations, you must conduct three 
separate test runs for each performance test required in this section, 
as specified in Sec.  63.7(e)(3). Each test run must last at least 1 
hour.
    (e) The emission rate of particulate matter (PM) from each lime kiln 
(and each lime cooler if there is a separate exhaust to the atmosphere 
from the lime cooler) must be computed for each run using Equation 1 of 
this section:

    (i) A test must include three or more runs in which a pair of 
samples is obtained simultaneously for each run according to section 
11.2.6 of ASTM Method D6735-01.
    (ii) You must calculate the test run standard deviation of each set 
of paired samples to quantify data precision, according to Equation 1 of 
this section:

[[Page 81]]

[GRAPHIC] [TIFF OMITTED] TR05JA04.003

Where:

RSDa = The test run relative standard deviation of sample 
          pair a, percent.
C1a and C2a = The HCl concentrations, milligram/
          dry standard cubic meter(mg/dscm), from the paired samples.

    (iii) You must calculate the test average relative standard 
deviation according to Equation 2 of this section:
[GRAPHIC] [TIFF OMITTED] TR05JA04.004

Where:

RSDTA = The test average relative standard deviation, 
          percent.
RSDa = The test run relative standard deviation for sample 
          pair a.
p = The number of test runs, =3.

    (iv) If RSD\TA\ is greater than 20 percent, the data are invalid and 
the test must be repeated.
    (v) The post-test analyte spike procedure of section 11.2.7 of ASTM 
Method D6735-01 is conducted, and the percent recovery is calculated 
according to section 12.6 of ASTM Method D6735-01.
    (vi) If the percent recovery is between 70 percent and 130 percent, 
inclusive, the test is valid. If the percent recovery is outside of this 
range, the data are considered invalid, and the test must be repeated.
    (b) If you conduct tests to determine the rates of emission of 
specific organic HAP from lime kilns at LMP for use in applicability 
determinations under Sec.  63.7081, you may use either:
    (1) Method 320 of appendix A to this part, or
    (2) Method 18 of appendix A to part 60 of this chapter, or
    (3) ASTM D6420-99, Standard Test Method for Determination of Gaseous 
Organic Compounds by Direct Interface Gas Chromatography-Mass 
Spectrometry (GC/MS), provided that the provisions of paragraphs 
(b)(3)(i) through (iv) of this section are followed:
    (i) The target compound(s) are those listed in section 1.1 of ASTM 
D6420-99;
    (ii) The target concentration is between 150 parts per billion by 
volume and 100 parts per million by volume;
    (iii) For target compound(s) not listed in Table 1.1 of ASTM D6420-
99, but potentially detected by mass spectrometry, the additional system 
continuing calibration check after each run, as detailed in section 
10.5.3 of ASTM D6420-99, is conducted, met, documented, and submitted 
with the data report, even if there is no moisture condenser used or the 
compound is not considered water soluble; and
    (iv) For target compound(s) not listed in Table 1.1 of ASTM D6420-
99, and not amenable to detection by mass spectrometry, ASTM D6420-99 
may not be used.
    (c) It is left to the discretion of the permitting authority whether 
or not idled kilns must be tested for (HCl) to claim area source status. 
If the facility has kilns that use common feed materials and fuel, are 
essentially identical in design, and use essentially identical emission 
controls, the permitting authority may also determine if one kiln can be 
tested, and the HCl emissions for the other essentially identical kilns 
be estimated from that test.

 Subpart BBBBB_National Emission Standards for Hazardous Air Pollutants 
                     for Semiconductor Manufacturing

    Source: 68 FR 27925, May 22, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec.  63.7180  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for semiconductor manufacturing facilities. This 
subpart also establishes requirements to demonstrate initial and 
continuous compliance with the emission standards.



Sec.  63.7181  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a 
semiconductor manufacturing process unit that is a major source of 
hazardous air pollutants (HAP) emissions or that is located at, or is 
part of, a major source of HAP emissions.
    (b) A major source of HAP emissions is any stationary source or 
group of stationary sources located within a contiguous area and under 
common control that emits or has the potential to emit, considering 
controls, in the aggregate, any single HAP at a rate of 10 tons per year 
(tpy) or more or any combination of HAP at a rate of 25 tpy or more.



Sec.  63.7182  What parts of my facility does this subpart cover?

    (a) This subpart applies to each new, reconstructed, or existing 
affected source that you own or operate that manufactures 
semiconductors.
    (b) An affected source subject to this subpart is the collection of 
all semiconductor manufacturing process units used to manufacture p-type 
and n-type semiconductors and active solid-state devices from a wafer 
substrate, including research and development activities integrated into 
a semiconductor

[[Page 95]]

manufacturing process unit. A semiconductor manufacturing process unit 
includes the equipment assembled and connected by ductwork or hard-
piping including furnaces and associated unit operations; associated wet 
and dry work benches; associated recovery devices; feed, intermediate, 
and product storage tanks; product transfer racks and connected ducts 
and piping; pumps, compressors, agitators, pressure-relief devices, 
sampling connecting systems, open-ended valves or lines, valves, 
connectors, and instrumentation systems; and control devices.
    (c) Your affected source is a new affected source if you commence 
construction of the affected source after May 8, 2002, and you meet the 
applicability criteria in Sec.  63.7181 at the time you commence 
construction.
    (d) Your affected source is a reconstructed affected source if you 
meet the criteria for ``reconstruction,'' as defined in Sec.  63.2.
    (e) Your source is an existing affected source if it is not a new or 
reconstructed affected source.



Sec.  63.7183  When do I have to comply with this subpart?

    (a) If you have a new or reconstructed affected source, you must 
comply with this subpart according to paragraphs (a)(1) and (2) of this 
section.
    (1) If you start up your affected source before May 22, 2003, then 
you must comply with the emission standards for new and reconstructed 
sources in this subpart no later than May 22, 2003.
    (2) If you start up your affected source after May 22, 2003, then 
you must comply with the emission standards for new and reconstructed 
sources in this subpart upon startup of your affected source.
    (b) If you have an existing affected source, you must comply with 
the emission standards for existing sources no later than 3 years from 
May 22, 2003.
    (c) If you have an area source that increases its emissions or its 
potential to emit such that it becomes a major source of HAP and an 
affected source subject to this subpart, paragraphs (c)(1) and (2) of 
this section apply.
    (1) Any portion of your existing facility that is a new affected 
source as specified at Sec.  63.7182(c), or a reconstructed affected 
source as specified at Sec.  63.7182(d), must be in compliance with this 
subpart upon startup.
    (2) Any portion of your facility that is an existing affected 
source, as specified at Sec.  63.7182(e), must be in compliance with 
this subpart by not later than 3 years after it becomes a major source.
    (d) You must meet the notification requirements in Sec.  63.7189 and 
in subpart A of this part. You must submit some of the notifications 
(e.g., Initial Notification) before the date you are required to comply 
with the emission limitations in this subpart.

                           Emission Standards



Sec.  63.7184  What emission limitations, operating limits, and work practice standards must I meet?

    (a) If you have a new, reconstructed, or existing affected source, 
as defined in Sec.  63.7182(b), you must comply with all applicable 
emission limitations in this section on and after the compliance dates 
specified in Sec.  63.7183.
    (b) Process vents--organic HAP emissions. For each organic HAP 
process vent, other than process vents from storage tanks, you must 
limit organic HAP emissions to the level specified in paragraph (b)(1) 
or (2) of this section. These limitations can be met by venting 
emissions from your process vent through a closed vent system to any 
combination of control devices meeting the requirements of Sec.  
63.982(a)(2).
    (1) Reduce the emissions of organic HAP from the process vent stream 
by 98 percent by weight.
    (2) Reduce or maintain the concentration of emitted organic HAP from 
the process vent to less than or equal to 20 parts per million by volume 
(ppmv).
    (c) Process vents--inorganic HAP emissions. For each inorganic HAP 
process vent, other than process vents from storage tanks, you must 
limit inorganic HAP emissions to the level specified in paragraph (c)(1) 
or (2) of this section. These limitations can be met by venting 
emissions from your process vent through a closed vent system to a 
halogen scrubber meeting the requirements of Sec. Sec.  63.983 (closed 
vent system requirements) and Sec.  63.994 (halogen

[[Page 96]]

scrubber requirements); the applicable general monitoring requirements 
of Sec.  63.996; the applicable performance test requirements; and the 
monitoring, recordkeeping and reporting requirements referenced therein.
    (1) Reduce the emissions of inorganic HAP from the process vent 
stream by 95 percent by weight.
    (2) Reduce or maintain the concentration of emitted inorganic HAP 
from the process vent to less than or equal to 0.42 ppmv.
    (d) Storage tanks. For each storage tank, 1,500 gallons or larger, 
you must limit total HAP emissions to the level specified in paragraph 
(d)(1) or (2) of this section if the emissions from the storage tank 
vent contains greater than 0.42 ppmv inorganic HAP. These limitations 
can be met by venting emissions from your storage tank through a closed 
vent system to a halogen scrubber meeting the requirements of Sec. Sec.  
63.983 (closed vent system requirements) and 63.994 (halogen scrubber 
requirements); the applicable general monitoring requirements of Sec.  
63.996; the applicable performance test requirements; and the 
monitoring, recordkeeping and reporting requirements referenced therein.
    (1) Reduce the emissions of inorganic HAP from each storage tank by 
95 percent by weight.
    (2) Reduce or maintain the concentration of emitted inorganic HAP 
from the process vent to less than or equal to 0.42 ppmv.
    (e) You must comply with the applicable work practice standards and 
operating limits contained in Sec.  63.982(a)(1) and (2). The closed 
vent system inspection requirements of Sec.  63.983(c), as referenced by 
Sec.  63.982(a)(1) and (2), do not apply.
    (f) Process vents--combined HAP emissions. For each combined HAP 
process vent, other than process vents from storage tanks, you must

Sec.  63.7186  By what date must I conduct performance tests or other
initial compliance demonstrations?

    For each process vent or storage tank vent emission limitation in 
Sec.  63.7184 for which initial compliance is demonstrated by meeting a 
percent by weight HAP emissions reduction, or a HAP concentration 
limitation, you must conduct performance tests or an initial compliance 
demonstration within 180 days after the compliance date that is 
specified for your source in Sec.  63.7183 and according to the 
provisions in Sec.  63.7(a)(2).



Sec.  63.7187  What performance tests and other compliance procedures
must I use?

    (a) You must conduct each performance test in Table 1 to this 
subpart

[[Page 97]]

that applies to you as specified for process vents in Sec.  63.982(a)(2)

conducted under maximum operating conditions or HAP emissions potential. 
Section 63.982(a)(1) and (2) only includes methods to measure the total 
organic regulated material or total organic carbon (TOC) concentration. 
The EPA Methods 26 and 26A are included in Table 1 to this subpart in 
addition to the test methods contained within Sec.  63.982(a)(1) and 
(2). The EPA Method 26 or 26A must be used for testing regulated 
material containing inorganic HAP. Method 320 of 40 CFR part 63, 
appendix A, must be used to measure total vapor phase organic and 
inorganic HAP concentrations.
    (b) If, without the use of a control device, your process vent 
stream has an organic HAP concentration of 20 ppmv or less or an 
inorganic HAP concentration of 0.42 ppmv or less, or your storage tank 
vent stream has an inorganic HAP concentration of 0.42 ppmv or less, you 
may demonstrate that the vent stream is compliant by engineering 
assessments and calculations or by conducting the applicable performance 
test requirements specified in Table 1 to this subpart. Your engineering 
assessments and calculations, as with performance tests (as specified in 
Sec.  63.982(a)(1) and (2)), must represent your maximum operating 
conditions or HAP emissions potential and must be approved by the 
Administrator. You must demonstrate continuous compliance by certifying 
that your operations will not exceed the maximum operating conditions or 
HAP emissions potential represented by your engineering assessments, 
calculations, or performance test.
    (c) If you are using a control device to comply with the emission 
limitations in Sec.  63.7184 and the inlet concentration of HAP to the 
control device is 20 ppmv or less, then you may demonstrate that the 
control device meets the percent by weight HAP emission reduction 
limitation in Sec.  63.7184(c)(1) or (d)(1) by conducting a design 
evaluation as specified in paragraph (i) of this section. Your design 
evaluation must represent your maximum operating conditions or HAP 
emissions potential and must be approved by the Administrator. You must 
demonstrate continuous compliance by certifying that your operations 
will not exceed the maximum operating conditions or HAP emissions 
potential represented by your design evaluation.

    (e) For each monitoring system required in this section, you must 
develop and submit for approval a site-specific monitoring plan that 
addresses the criteria specified in paragraphs (e)(1) through (3) of 
this section.
    (1) Installation of the continuous monitoring system (CMS) sampling 
probe or other interface at a measurement location relative to each 
affected process unit such that the measurement is representative of 
control of the exhaust emissions (e.g., on or downstream of the last 
control device);
    (2) Performance and equipment specifications for the sample 
interface, the pollutant concentration or parametric signal analyzer, 
and the data collection and reduction system; and
    (3) Performance evaluation procedures and acceptance criteria (e.g., 
calibrations).
    (f) In your site-specific monitoring plan, you must also address the 
procedural processes in paragraphs (f)(1) through (3) of this section.
    (1) Ongoing operation and maintenance procedures in accordance with 
the general requirements of Sec.  63.8(c)(1), (3), (4)(ii), (7), and 
(8);

general requirements of Sec.  63.8(d); and
    (3) Ongoing recordkeeping and reporting procedures in accordance 
with the general requirements of Sec.  63.10(c), (e)(1), and (e)(2)(i).
    (g) You must conduct a performance evaluation of each CMS in 
accordance with your site-specific monitoring plan.
    (h) You must operate and maintain the CMS in continuous operation 
according to the site-specific monitoring plan.
    (i) Design evaluation. To demonstrate that a control device meets 
the required percent by weight inorganic HAP emission reduction 
limitation in Sec.  63.7184(c)(1) or (d)(1), a design evaluation must 
address the composition of

[[Page 98]]

the inorganic HAP concentration of the vent stream entering the control 
device. A design evaluation also must address other vent stream 
characteristics and control device operating parameters as specified in 
any one of paragraphs (i)(1) through (5) of this section, depending on 
the type of control device that is used. If the vent stream is not the 
only inlet to the control device, the efficiency demonstration must also 
consider all other vapors, gases, and liquids, other than fuels, 
received by the control device.
    (1) For a condenser, the design evaluation shall consider the vent 
stream flow rate, relative humidity, and temperature and shall establish 
the design outlet organic HAP compound concentration level, design 
average temperature of the condenser exhaust vent stream, and the design 
average temperatures of the coolant fluid at the condenser inlet and 
outlet. The temperature of the gas stream exiting the condenser must be 
measured and used to establish the outlet organic HAP concentration.
    (2) For a carbon adsorption system that regenerates the carbon bed 
directly onsite in the control device such as a fixed-bed adsorber, the 
design evaluation shall consider the vent stream flow rate, relative 
humidity, and temperature and shall establish the design exhaust vent 
stream organic compound concentration level, adsorption cycle time, 
number and capacity of carbon beds, type and working capacity of 
activated carbon used for carbon beds, design total regeneration stream 
mass or volumetric flow over the period of each complete carbon bed 
regeneration cycle, design carbon bed temperature after regeneration, 
design carbon bed regeneration time, and design service life of carbon. 
For vacuum desorption, the pressure drop shall be included.
    (3) For a carbon adsorption system that does not regenerate the 
carbon bed directly onsite in the control device such as a carbon 
canister, the design evaluation shall consider the vent stream mass or 
volumetric flow rate, relative humidity, and temperature and shall 
establish the design exhaust vent stream organic compound concentration 
level, capacity of carbon bed, type and working capacity of activated 
carbon used for carbon bed, and design carbon replacement interval based 
on the total carbon working capacity of the control device and source 
operating schedule.
    (4) For a scrubber, the design evaluation shall consider the vent 
stream composition, constituent concentrations, liquid-to-vapor ratio, 
scrubbing liquid flow rate and concentration, temperature, and the 
reaction kinetics of the constituents with the scrubbing liquid. The 
design evaluation shall establish the design exhaust vent stream organic 
compound concentration level and will include the additional information 
in paragraphs (i)(5)(i) and (ii) of this section for trays and a packed 
column scrubber.
    (i) Type and total number of theoretical and actual trays;
    (ii) Type and total surface area of packing for entire column, and 
for individual packed sections if column contains more than one packed 
section.

part 63, subpart A), and in this section as follows:
    Combined HAP process vent means a process vent that emits both 
inorganic and organic HAP to the atmosphere.
    Control device means a combustion device, recovery device, recapture 
device, or any combination of these devices used for the primary purpose 
of reducing emissions to comply with this subpart. Devices that are 
inherent to a process or are integral to the operation of a process are 
not considered control devices for the purposes of this subpart, even

emissions.

[[Page 102]]

    Inorganic HAP process vent means a process vent that emits only 
inorganic HAP to the atmosphere.
    Organic HAP process vent means a process vent that emits only 
organic HAP to the atmosphere.
    Process vent means the point at which HAP emissions are released to 
the atmosphere from a semiconductor manufacturing process unit or 
storage tank by means of a stack, chimney, vent, or other functionally 
equivalent opening. The HAP emission points originating from wastewater 
treatment equipment, other than storage tanks, are not considered to be 
a process vent, unless the wastewater treatment equipment emission 
points are connected to a common vent or exhaust plenum with other 
process vents.
    Semiconductor manufacturing means the collection of semiconductor 
manufacturing process units used to manufacture p-type and n-type 
semiconductors or active solid state devices from a wafer substrate, 
including processing from crystal growth through wafer fabrication, and

devices include semiconductor diodes, semiconductor stacks, rectifiers, 
integrated circuits, and transistors.
    Semiconductor manufacturing process unit means the collection of 
equipment used to carry out a discrete operation in the semiconductor 
manufacturing process. These operations include, but are not limited to, 
crystal growing; solvent stations used to prepare and clean materials 
for subsequent processing or for parts cleaning; wet chemical stations 
used for cleaning (other than solvent cleaning); photoresist 
application, developing, and stripping; etching; gaseous operation 
stations used for stripping, cleaning, doping, etching, and layering; 
separation; encapsulation; and testing. Research and development 
operations associated with semiconductor manufacturing and conducted at 
a semiconductor manufacturing facility are considered to be 
semiconductor manufacturing process units.
    Storage tank means a stationary unit that is constructed primarily 
from nonearthen materials (such as wood, concrete, steel, fiberglass, or 
plastic) which provides structural support and is designed to hold an 
accumulation of liquids or other materials used in or generated by a 
semiconductor manufacturing process unit. The following are not storage 
tanks for the purposes of this subpart:
    (1) Tanks permanently attached to motor vehicles such as trucks, 
railcars, barges, or ships;
    (2) Flow-through tanks where wastewater undergoes treatment (such as 
pH adjustment) before discharge, and are not used to accumulate

                        What This Subpart Covers



Sec.  63.7280  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for pushing, soaking, quenching, and battery 
stacks at coke oven batteries. This subpart also establishes 
requirements to demonstrate initial and continuous compliance with all 
applicable emission limitations, work practice standards, and operation 
and maintenance requirements in this subpart.



Sec.  63.7281  Am I subject to this subpart?

    You are subject to this subpart if you own or operate a coke oven 
battery at a coke plant that is (or is part of) a major source of 
hazardous air pollutant (HAP) emissions. A major source of HAP is a 
plant site that emits or has the potential to emit any single HAP at a 
rate of 10 tons or more per year or any combination of HAP at a rate of 
25 tons or more per year.



Sec.  63.7282  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new or existing affected source at 
your coke plant. The affected source is each coke oven battery.
    (b) This subpart covers emissions from pushing, soaking, quenching, 
and battery stacks from each affected source.
    (c) An affected source at your coke plant is existing if you 
commenced construction or reconstruction of the affected source before 
July 3, 2001.
    (d) An affected source at your coke plant is new if you commenced 
construction or reconstruction of the affected source on or after July 
3, 2001. An affected source is reconstructed if it meets the definition 
of ``reconstruction'' in Sec.  63.2.

            Emission Limitations and Work Practice Standards



Sec.  63.7290  What emission limitations must I meet for capture systems and control devices applied to pushing emissions?

    (a) You must not discharge to the atmosphere emissions of 
particulate matter from a control device applied to pushing emissions 
from a new or existing coke oven battery that exceed the applicable 
limit in paragraphs (a)(1) through (4) of this section:
    (1) 0.01 grain per dry standard cubic foot (gr/dscf) if a cokeside 
shed is used to capture emissions;
    (2) 0.02 pound per ton (lb/ton) of coke if a moveable hood vented to 
a stationary control device is used to capture emissions;
    (3) If a mobile scrubber car that does not capture emissions during 
travel is used:
    (i) 0.03 lb/ton of coke for a control device applied to pushing 
emissions from a short battery, or
    (ii) 0.01 lb/ton of coke for a control device applied to pushing 
emissions from a tall battery; and
    (4) 0.04 lb/ton of coke if a mobile control device that captures 
emissions during travel is used.
    (b) You must meet each operating limit in paragraphs (b)(1) through 
(4) of this section that applies to you for a new or existing coke oven 
battery.
    (1) For each venturi scrubber applied to pushing emissions, you must 
maintain the daily average pressure drop and scrubber water flow rate at 
or above the minimum levels established during the initial performance 
test.
    (2) For each hot water scrubber applied to pushing emissions, you 
must maintain the daily average water pressure and water temperature at 
or above the minimum levels established during the initial performance 
test.
    (3) For each capture system applied to pushing emissions, you must 
maintain the daily average volumetric flow rate at the inlet of the 
control device at or above the minimum level established during the 
initial performance test; or
    (i) For each capture system that uses an electric motor to drive the 
fan, you must maintain the daily average fan motor amperes at or above 
the minimum level established during the initial performance test; and
    (ii) For each capture system that does not use a fan driven by an 
electric motor, you must maintain the daily average static pressure at 
the inlet to the control device at an equal or greater vacuum than the 
level established during the initial performance test or maintain the 
daily average fan revolutions per minute (RPM) at or above the minimum 
level established during the initial performance test.
    (4) For each multicyclone, you must maintain the daily average 
pressure drop at or below the minimum level established during the 
initial performance test.

Sec.  63.7291  What work practice standards must I meet for fugitive
pushing emissions if I have a by-product coke oven battery with vertical
flues?

    (a) You must meet each requirement in paragraphs (a)(1) through (7) 
of this section for each new or existing by-product coke oven battery 
with vertical flues.
    (1) Observe and record the opacity of fugitive pushing emissions 
from each oven at least once every 90 days. If an oven cannot be 
observed during a 90-day period due to circumstances that were not 
reasonably avoidable, you must observe the opacity of the first push of 
that oven following the close of the 90-day period that is capable of 
being observed in accordance with the procedures in Sec.  63.7334(a), 
and you must document why the oven was not observed within a 90-day 
period. All opacity observations of fugitive pushing emissions for 
batteries with vertical flues must be made using the procedures in Sec.  
63.7334(a).
    (2) If two or more batteries are served by the same pushing 
equipment and total no more than 90 ovens, the batteries as a unit can 
be considered a single battery.
    (3) Observe and record the opacity of fugitive pushing emissions for 
at least four consecutive pushes per battery each day. Exclude any push 
during which the observer's view is obstructed or obscured by 
interferences and observe the next available push to complete the set of 
four pushes. If necessary due to circumstances that were not reasonably 
avoidable, you may observe fewer than four consecutive pushes in a day; 
however, you must observe and record as many consecutive pushes as 
possible and document why four consecutive pushes could not be observed. 
You may observe and record one or more non-consecutive pushes in 
addition to any consecutive pushes observed in a day.
    (4) Do not alter the pushing schedule to change the sequence of 
consecutive pushes to be observed on any day. Keep records indicating 
the legitimate operational reason for any change in your pushing 
schedule which results in a change in the sequence of consecutive pushes 
observed on any day.
    (5) If the average opacity for any individual push exceeds 30 
percent opacity for any short battery or 35 percent opacity for any tall 
battery, you must take corrective action and/or increase coking time for 
that oven. You must complete corrective action or increase coking time 
within either 10 calendar days or the number of days determined using 
Equation 1 of this section, whichever is greater:

X = 0.55 * Y (Eq. 1)

Where:

X = Number of calendar days allowed to complete corrective action or 
          increase coking time; and
Y = Current coking time for the oven, hours.


For the purpose of determining the number of calendar days allowed under 
Equation 1 of this section, day one is the first day following the day 
you observed an opacity in excess of 30 percent for any short battery or 
35 percent for any tall battery. Any fraction produced by Equation 1 of 
this section must be counted as a whole day. Days during which the oven 
is removed from service are not included in the number of days allowed 
to complete corrective action.
    (6)(i) You must demonstrate that the corrective action and/or 
increased coking time was successful. After a period of time no longer 
than the number of days allowed in paragraph (a)(5) of this section, 
observe and record the opacity of the first two pushes for the oven 
capable of being observed using the procedures in Sec.  63.7334(a). The 
corrective action and/or increased coking time was successful if the 
average opacity for each of the two pushes is 30 percent or less for a 
short battery or 35 percent or less for a tall battery. If the 
corrective action and/or increased coking time was successful, you may 
return the oven to the 90-day reading rotation described in paragraph 
(a)(1) of this section. If the average opacity of either push exceeds 30 
percent for a short battery or 35 percent for a tall battery, the 
corrective action and/or increased coking time was unsuccessful, and you 
must complete additional corrective action and/or increase coking time 
for that oven within the number of days allowed in paragraph (a)(5) of 
this section.

[[Page 107]]

    (ii) After implementing any additional corrective action and/or 
increased coking time required under paragraph (a)(6)(i) or (a)(7)(ii) 
of this section, you must demonstrate that corrective action and/or 
increased coking time was successful. After a period of time no longer 
than the number of days allowed in paragraph (a)(5) of this section, you 
must observe and record the opacity of the first two pushes for the oven 
capable of being observed using the procedures in Sec.  63.7334(a). The 
corrective action and/or increased coking time was successful if the 
average opacity for each of the two pushes is 30 percent or less for a 
short battery or 35 percent or less for a tall battery. If the 
corrective action and/or increased coking time was successful, you may 
return the oven to the 90-day reading rotation described in paragraph 
(a)(1) of this section. If the average opacity of either push exceeds 30 
percent for a short battery or 35 percent for a tall battery, the 
corrective action and/or increased coking time was unsuccessful, and you 
must follow the procedures in paragraph (a)(6)(iii) of this section.
    (iii) If the corrective action and/or increased coking time was 
unsuccessful as described in paragraph (a)(6)(ii) of this section, you 
must repeat the procedures in paragraph (a)(6)(ii) of this section until 
the corrective action and/or increased coking time is successful. You 
must report to the permitting authority as a deviation each unsuccessful 
attempt at corrective action and/or increased coking time under 
paragraph (a)(6)(ii) of this section.
    (7)(i) If at any time you place an oven on increased coking time as 
a result of fugitive pushing emissions that exceed 30 percent for a 
short battery or 35 percent for a tall battery, you must keep the oven 
on the increased coking time until the oven qualifies for decreased 
coking time using the procedures in paragraph (a)(7)(ii) or (a)(7)(iii) 
of this section.
    (ii) To qualify for a decreased coking time for an oven placed on 
increased coking time in accordance with paragraph (a)(5) or (6) of this 
section, you must operate the oven on the decreased coking time. After 
no more than two coking cycles on the decreased coking time, you must 
observe and record the opacity of the first two pushes that are capable 
of being observed using the procedures in Sec.  63.7334(a). If the 
average opacity for each of the two pushes is 30 percent or less for a 
short battery or 35 percent or less for a tall battery, you may keep the 
oven on the decreased coking time and return the oven to the 90-day 
reading rotation described in paragraph (a)(1) of this section. If the 
average opacity of either push exceeds 30 percent for a short battery or 
35 percent for a tall battery, the attempt to qualify for a decreased 
coking time was unsuccessful. You must then return the oven to the 
previously established increased coking time, or implement other 
corrective action(s) and/or increased coking time. If you implement 
other corrective action and/or a coking time that is shorter than the 
previously established increased coking time, you must follow the 
procedures in paragraph (a)(6)(ii) of this section to confirm that the 
corrective action(s) and/or increased coking time was successful.
    (iii) If the attempt to qualify for decreased coking time was 
unsuccessful as described in paragraph (a)(7)(ii) of this section, you 
may again attempt to qualify for decreased coking time for the oven. To 
do this, you must operate the oven on the decreased coking time. After 
no more than two coking cycles on the decreased coking time, you must 
observe and record the opacity of the first two pushes that are capable 
of being observed using the procedures in Sec.  63.7334(a). If the 
average opacity for each of the two pushes is 30 percent or less for a 
short battery or 35 percent or less for a tall battery, you may keep the 
oven on the decreased coking time and return the oven to the 90-day 
reading rotation described in paragraph (a)(1) of this section. If the 
average opacity of either push exceeds 30 percent for a short battery or 
35 percent for a tall battery, the attempt to qualify for a decreased 
coking time was unsuccessful. You must then return the oven to the 
previously established increased coking time, or implement other 
corrective action(s) and/or increased coking time. If you implement 
other corrective action and/or a coking time that is shorter than the 
previously established increased coking

[[Page 108]]

time, you must follow the procedures in paragraph (a)(6)(ii) of this 
section to confirm that the corrective action(s) and/or increased coking 
time was successful.
    (iv) You must report to the permitting authority as a deviation the 
second and any subsequent consecutive unsuccessful attempts on the same 
oven to qualify for decreased coking time as described in paragraph 
(a)(7)(iii) of this section.
    (b) As provided in Sec.  63.6(g), you may request to use an 
alternative to the work practice standards in paragraph (a) of this 
section.



Sec.  63.7292  What work practice standards must I meet for fugitive
pushing emissions if I have a by-product coke oven battery with horizontal
flues?

    (a) You must comply with each of the requirements in paragraphs 
(a)(1) through (4) of this section.
    (1) Prepare and operate by a written plan that will eliminate or 
minimize incomplete coking for each by-product coke oven battery with 
horizontal flues. You must submit the plan and supporting documentation 
to the Administrator (or delegated authority) for approval no later than 
90 days after completing all observations and measurements required for 
the study in paragraph (a)(3) of this section or April 14, 2004, 
whichever is earlier. You must begin operating by the plan requirements 
by the compliance date that is specified in Sec.  63.7283. The written 
plan must identify minimum flue temperatures for different coking times 
and a battery-wide minimum acceptable flue temperature for any oven at 
any coking time.
    (2) Submit the written plan and supporting documentation to the 
Administrator (or delegated authority) for review and approval. Include 
all data collected during the study described in paragraph (a)(3) of 
this section. If the Administrator (or delegated authority) disapproves 
the plan, you must revise the plan as directed by the Administrator (or 
delegated authority) and submit the amended plan for approval. The 
Administrator (or delegated authority) may require you to collect and 
submit additional data. You must operate according to your submitted 
plan (or submitted amended plan, if any) until the Administrator (or 
delegated authority) approves your plan.
    (3) You must base your written plan on a study that you conduct that 
meets each of the requirements listed in paragraphs (a)(3)(i) through 
(x) of this section.
    (i) Initiate the study by July 14, 2003. Notify the Administrator 
(or delegated authority) at least 7 days prior to initiating the study 
according to the requirements in Sec.  63.7340(f).
    (ii) Conduct the study under representative operating conditions, 
including but not limited to the range of moisture content and volatile 
matter in the coal that is charged.
    (iii) Include every oven in the study and observe at least two 
pushes from each oven.
    (iv) For each push observed, measure and record the temperature of 
every flue within 2 hours before the scheduled pushing time. Document 
the oven number, date, and time the oven was charged and pushed, and 
calculate the net coking time.
    (v) For each push observed, document the factors to be used to 
identify pushes that are incompletely coked. These factors must include 
(but are not limited to): average opacity during the push, average 
opacity during travel to the quench tower, average of six highest 
consecutive observations during both push and travel, highest single 
opacity reading, color of the emissions (especially noting any yellow or 
brown emissions), presence of excessive smoke during travel to the 
quench tower, percent volatile matter in the coke, percent volatile 
matter and percent moisture in the coal that is charged, and the date 
the oven was last rebuilt or completely relined. Additional 
documentation may be provided in the form of pictures or videotape of 
emissions during the push and travel. All opacity observations must be 
conducted in accordance with the procedures in Sec.  63.7334(a)(3) 
through (7).
    (vi) Inspect the inside walls of the oven after each observed push 
for cool spots as indicated by a flue that is darker than others (the 
oven walls should be red hot) and record the results.

[[Page 109]]

    (vii) For each push observed, note where incomplete coking occurs if 
possible (e.g., coke side end, pusher side end, top, or center of the 
coke mass). For any push with incomplete coking, investigate and 
document the probable cause.
    (viii) Use the documented factors in paragraph (a)(3)(v) of this 
section to identify pushes that were completely coked and those that 
were not completely coked. Provide a rationale for the determination 
based on the documentation of factors observed during the study.
    (ix) Use only the flue temperature and coking time data for pushes 
that were completely coked to identify minimum flue temperatures for 
various coking times. Submit the criteria used to determine complete 
coking, as well as a table of coking times and corresponding 
temperatures for complete coking as part of your plan.
    (x) Determine the battery-wide minimum acceptable flue temperature 
for any oven. This temperature will be equal to the lowest temperature 
that provided complete coking as determined in paragraph (a)(3)(ix) of 
this section.
    (4) You must operate according to the coking times and temperatures 
in your approved plan and the requirements in paragraphs (a)(4)(i) 
through (viii) of this section.
    (i) Measure and record the percent volatile matter in the coal that 
is charged.
    (ii) Measure and record the temperature of all flues on two ovens 
per day within 2 hours before the scheduled pushing time for each oven. 
Measure and record the temperature of all flues on each oven at least 
once each month.
    (iii) For each oven observed in accordance with paragraph (a)(4)(ii) 
of this section, record the time each oven is charged and pushed and 
calculate and record the net coking time. If any measured flue 
temperature for an oven is below the minimum flue temperature for an 
oven's scheduled coking time as established in the written plan, 
increase the coking time for the oven to the coking time in the written 
plan for the observed flue temperature before pushing the oven.
    (iv) If you increased the coking time for any oven in accordance 
with paragraph (a)(4)(iii) of this section, you must investigate the 
cause of the low flue temperature and take corrective action to fix the 
problem. You must continue to measure and record the temperature of all 
flues for the oven within 2 hours before each scheduled pushing time 
until the measurements meet the minimum temperature requirements for the 
increased coking time for two consecutive pushes. If any measured flue 
temperature for an oven on increased coking time falls below the minimum 
flue temperature for the increased coking time, as established in the 
written plan, you must increase the coking time for the oven to the 
coking time specified in the written plan for the observed flue 
temperature before pushing the oven. The oven must continue to operate 
at this coking time (or at a longer coking time if the temperature falls 
below the minimum allowed for the increased coking time) until the 
problem has been corrected, and you have confirmed that the corrective 
action was successful as required by paragraph (a)(4)(v) of this 
section.
    (v) Once the heating problem has been corrected, the oven may be 
returned to the battery's normal coking schedule. You must then measure 
and record the flue temperatures for the oven within 2 hours before the 
scheduled pushing time for the next two consecutive pushes. If any flue 
temperature measurement is below the minimum flue temperature for that 
coking time established in the written plan, repeat the procedures in 
paragraphs (a)(4)(iii) and (iv) of this section.
    (vi) If any flue temperature measurement is below the battery-wide 
minimum acceptable temperature for complete coking established in the 
written plan for any oven at any coking time, you must remove the oven 
from service for repairs.
    (vii) For an oven that has been repaired and returned to service 
after being removed from service in accordance with paragraph (a)(4)(vi) 
of this section, you must measure and record the temperatures of all 
flues for the oven within 2 hours before the first scheduled pushing 
time. If any flue

[[Page 110]]

temperature measurement is below the minimum flue temperature for the 
scheduled coking time, as established in the written plan, you must 
repeat the procedures described in paragraphs (a)(4)(iii) and (iv) of 
this section.
    (viii) For an oven that has been repaired and returned to service 
after removal from service in accordance with paragraph (a)(4)(vi) of 
this section, you must report as a deviation to the permitting authority 
any flue temperature measurement made during the initial coking cycle 
after return to service that is below the lowest acceptable minimum flue 
temperature.
    (b) As provided in Sec.  63.6(g), you may request to use an 
alternative to the work practice standards in paragraph (a) of this 
section.



Sec.  63.7293  What work practice standards must I meet for fugitive
pushing emissions if I have a non-recovery coke oven battery?

    (a) You must meet the requirements in paragraphs (a)(1) and (2) of 
this section for each new and existing non-recovery coke oven battery.
    (1) You must visually inspect each oven prior to pushing by opening 
the door damper and observing the bed of coke.
    (2) Do not push the oven unless the visual inspection indicates that

prepare and operate at all times according to a written work practice 
plan for soaking. Each plan must include measures and procedures to:
    (1) Train topside workers to identify soaking emissions that require 
corrective actions.
    (2) Damper the oven off the collecting main prior to opening the 
standpipe cap.
    (3) Determine the cause of soaking emissions that do not ignite 
automatically, including emissions that result from raw coke oven gas 
leaking from the collecting main through the damper, and emissions that 
result from incomplete coking.
    (4) If soaking emissions are caused by leaks from the collecting 
main, take corrective actions to eliminate the soaking emissions. 
Corrective actions may include, but are not limited to, reseating the 
damper, cleaning the flushing liquor piping, using aspiration, putting 
the oven back on the collecting main, or igniting the emissions.
    (5) If soaking emissions are not caused by leaks from the collecting 
main, notify a designated responsible party. The responsible party must 
determine whether the soaking emissions are due to incomplete coking. If 
incomplete coking is the cause of the soaking emissions, you must put 
the oven back on the collecting main until it is completely coked or you 
must ignite the emissions.
    (b) As provided in Sec.  63.6(g), you may request to use an 
alternative to the work practice standard in paragraph (a) of this 
section.



Sec.  63.7295  What requirements must I meet for quenching?

oven battery, you must meet each of the requirements in paragraphs 
(b)(1) through (4) of this section.
    (1) You must equip each quench tower with baffles such that no more 
than 5 percent of the cross sectional area of the tower may be uncovered 
or open to the sky.
    (2) You must wash the baffles in each quench tower once each day 
that the tower is used to quench coke, except as specified in paragraphs 
(b)(2)(i) and (ii) of this section.
    (i) You are not required to wash the baffles in a quench tower if 
the highest measured ambient temperature remains less than 30 degrees 
Fahrenheit throughout that day (24-hour period). If the measured ambient 
temperature rises to 30 degrees Fahrenheit or more during the day, you 
must resume daily washing according to the schedule in your operation 
and maintenance plan.
    (ii) You must continuously record the ambient temperature on days 
that the baffles were not washed.
    (3) You must inspect each quench tower monthly for damaged or 
missing baffles and blockage.

of the physical appearance of the equipment (e.g., presence of holes in 
ductwork or hoods, flow constrictions caused by dents or accumulated 
dust in ductwork, and fan

[[Page 112]]

erosion). In the event a defect or deficiency is found in the capture 
system (during a monthly inspection or between inspections), you must 
complete repairs within 30 days after the date that the defect or 
deficiency is discovered. If you determine that the repairs cannot be 
completed within 30 days, you must submit a written request for an 
extension of time to complete the repairs that must be received by the 
permitting authority not more than 20 days after the date that the 
defect or deficiency is discovered. The request must contain a 
description of the defect or deficiency, the steps needed and taken to 
correct the problem, the interim steps being taken to mitigate the 
emissions impact of the defect or deficiency, and a proposed schedule 
for completing the repairs. The request shall be deemed approved unless 
and until such time as the permitting authority notifies you that it 
objects to the request. The permitting authority may consider all 
relevant factors in deciding whether to approve or deny the request 
(including feasibility and safety). Each approved schedule must provide

you must initiate corrective action to determine the cause of the alarm 
within 1 hour of the alarm, initiate corrective action to correct the 
cause of the problem within 24 hours of the alarm, and complete the 
corrective action as soon as practicable. Actions may include, but are 
not limited to:
    (i) Inspecting the baghouse for air leaks, torn or broken bags or 
filter media, or any other condition that may cause an increase in 
emissions.
    (ii) Sealing off defective bags or filter media.
    (iii) Replacing defective bags or filter media or otherwise 
repairing the control device.
    (iv) Sealing off a defective baghouse compartment.
    (v) Cleaning the bag leak detection system probe, or otherwise 
repairing the bag leak detection system.

demonstrate initial compliance with the emission limits for particulate
matter?

    (a) You must conduct each performance test that applies to your 
affected source according to the requirements in paragraph (b) of this 
section.
    (b) To determine compliance with the emission limit for particulate 
matter from a control device applied to pushing emissions where a 
cokeside shed is the capture system, follow the test methods and 
procedures in paragraphs (b)(1) and (2) of this section. To determine 
compliance with a process-weighted mass rate of particulate matter (lb/

Sec.  63.7323  What procedures must I use to establish operating limits?

    (a) For a venturi scrubber applied to pushing emissions from a coke 
oven battery, you must establish site-specific operating limits for 
pressure drop and scrubber water flow rate according to the procedures 
in paragraphs (a)(1) and (2) of this section.
    (1) Using the continuous parameter monitoring systems (CPMS) 
required in Sec.  63.7330(b), measure and record the pressure drop and 
scrubber water flow rate for each particulate matter test run during 
periods of pushing. A minimum of one pressure drop measurement and one 
scrubber water flow rate measurement must be obtained for each push.
    (2) Compute and record the average pressure drop and scrubber water 
flow rate for each test run. Your operating limits are the lowest 
average pressure drop and scrubber water flow rate values recorded 
during any of the three runs that meet the applicable emission limit.
    (b) For a hot water scrubber applied to pushing emissions from a 
coke oven battery, you must establish site-specific operating limits for 
water pressure and water temperature according to the procedures in 
paragraphs (b)(1) and (2) of this section.
    (1) Using the CPMS required in Sec.  63.7330(c), measure and record 
the hot water pressure and temperature for each particulate matter test 
run during periods of pushing. A minimum of one pressure measurement and 
one temperature measurement must be made just prior to each push by 
monitoring the hot water holding tank on the mobile scrubber car.
    (2) Compute and record the average water pressure and temperature 
for each test run. Your operating limits are the lowest pressure and 
temperature values recorded during any of the three runs that meet the 
applicable emission limit.
    (c) For a capture system applied to pushing emissions from a coke 
oven battery, you must establish a site-specific operating limit 
according to the procedures in paragraphs (c)(1), (2), or (3) of this 
section.
    (1) If you elect the operating limit in Sec.  63.7290(b)(3) for 
volumetric flow rate, measure and record the total volumetric flow rate 
at the inlet of the control device during each push sampled for each 
particulate matter test run. Your operating limit is the lowest 
volumetric flow rate recorded during any of the three runs that meet the 
emission limit.
    (2) If you elect the operating limit in Sec.  63.7290(b)(3)(i) for 
fan motor amperes, measure and record the fan motor amperes during each 
push sampled for each particulate matter test run. Your operating limit 
is the lowest fan motor amperes recorded during any of the three runs 
that meet the emission limit.
    (3) If you elect the operating limit in Sec.  63.7290(b)(3)(ii) for 
static pressure or fan RPM, measure and record the static pressure at 
the inlet of the control device or fan RPM during each push sampled for 
each particulate matter test run. Your operating limit for static 
pressure is the minimum vacuum recorded during any of the three runs 
that meets the emission limit. Your operating limit for fan RPM is the 
lowest fan RPM recorded during any of the three runs that meets the 
emission limit.
    (d) For a multicyclone applied to pushing emissions from a coke oven 
battery, you must establish a site-specific operating limit for pressure 
drop according to the procedures in paragraphs (d)(1) and (2) of this 
section.
    (1) Using the CPMS required in Sec.  63.7330(f), measure and record 
the pressure drop for each particulate matter test run during periods of 
pushing. A minimum of one pressure drop measurement must be obtained for 
each push.
    (2) Compute and record the average pressure drop for each test run. 
Your operating limit is the highest average

[[Page 115]]

pressure drop value recorded during any of the three runs that meet the 
emission limit.
    (e) You may change the operating limit for a venturi scrubber, 
capture system, or mobile control device that captures emissions during 
pushing if you meet the requirements in paragraphs (e)(1) through (3) of 
this section.
    (1) Submit a written notification to the Administrator of your

Sec.  63.7334  How do I demonstrate continuous compliance with the work
practice standards that apply to me?

    (a) For each by-product coke oven battery with vertical flues 
subject to the work practice standards for fugitive pushing emissions in 
Sec.  63.7291(a), you must demonstrate continuous compliance according 
to the requirements of paragraphs (a)(1) through (8) of this section:
    (1) Observe and record the opacity of fugitive emissions for four 
consecutive pushes per operating day, except you may make fewer or non-
consecutive observations as permitted by Sec.  63.7291(a)(3). Maintain 
records of the pushing schedule for each oven and records indicating the 
legitimate operational reason for any change in the pushing schedule 
according to Sec.  63.7291(a)(4).
    (2) Observe and record the opacity of fugitive emissions from each 
oven in a battery at least once every 90 days. If an oven cannot be 
observed during a 90-day period, observe and record the opacity of the 
first push of that oven following the close of the 90-day period that 
can be read in accordance with the procedures in paragraphs (a)(1) 
through (8) of this section.
    (3) Make all observations and calculations for opacity observations 
of fugitive pushing emissions in accordance with Method 9 in appendix A 
to 40 CFR part 60 using a Method 9 certified observer unless you have an 
approved alternative procedure under paragraph (a)(7) of this section.
    (4) Record pushing opacity observations at 15-second intervals as 
required in section 2.4 of Method 9 (appendix A to 40 CFR part 60). The 
requirement in section 2.4 of Method 9 for a minimum of 24 observations 
does not apply, and the data reduction requirements in section 2.5 of 
Method 9 do not apply. The requirement in Sec.  63.6(h)(5)(ii)(B) for 
obtaining at least 3 hours of observations (thirty 6-minute averages) to 
demonstrate initial compliance does not apply.
    (5) If fewer than six but at least four 15-second observations can 
be made, use the average of the total number of observations to 
calculate average opacity for the push. Missing one or more observations 
during the push (e.g., as the quench car passes behind a building) does 
not invalidate the observations before or after the interference for 
that push. However, a minimum of four 15-second readings must be made 
for a valid observation.

[[Page 123]]

    (6) Begin observations for a push at the first detectable movement 
of the coke mass. End observations of a push when the quench car enters 
the quench tower.
    (i) For a battery without a cokeside shed, observe fugitive pushing 
emissions from a position at least 10 meters from the quench car that 
provides an unobstructed view and avoids interferences from the topside 
of the battery. This may require the observer to be positioned at an 
angle to the quench car rather than perpendicular to it. Typical 
interferences to avoid include emissions from open standpipes and 
charging. Observe the opacity of emissions above the battery top with 
the sky as the background where possible. Record the oven number of any 
push not observed because of obstructions or interferences.
    (ii) For a battery with a cokeside shed, the observer must be in a 
position that provides an unobstructed view and avoids interferences 
from the topside of the battery. Typical interferences to avoid include 
emissions from open standpipes and charging. Observations must include 
any fugitive emissions that escape from the top of the shed, from the 
ends of the shed, or from the area where the shed is joined to the 
battery. If the observer does not have a clear view to identify when a 
push starts or ends, a second person can be positioned to signal the 
start or end of the push and notify the observer when to start or end 
the observations. Radio communications with other plant personnel (e.g., 
pushing ram operator or quench car operator) may also serve to notify 
the observer of the start or end of a push. Record the oven number of 
any push not observed because of obstructions or interferences.
    (iii) You may reposition after the push to observe emissions during 
travel if necessary.
    (7) If it is infeasible to implement the procedures in paragraphs 
(a)(1) through (6) of this section for an oven due to physical 
obstructions, nighttime pushes, or other reasons, you may apply to your 
permitting authority for permission to use an alternative procedure. The 
application must provide a detailed explanation of why it is infeasible 
to use the procedures in paragraphs (a)(1) through (6) of this section, 
identify the oven and battery numbers, and describe the alternative 
procedure. An alternative procedure must identify whether the coke in 
that oven is not completely coked, either before, during, or after an 
oven is pushed.
    (8) For each oven observed that exceeds an opacity of 30 percent for 
any short battery or 35 percent for any tall battery, you must take 
corrective action and/or increase the coking time in accordance with 
Sec.  63.7291(a). Maintain records documenting conformance with the 
requirements in Sec.  63.7291(a).
    (b) For each by-product coke oven battery with horizontal flues 
subject to the work practice standards for fugitive pushing emissions in 
Sec.  63.7292(a), you must demonstrate continuous compliance by having 
met the requirements of paragraphs (b)(1) through (3) of this section:
    (1) Measuring and recording the temperature of all flues on two 
ovens per day within 2 hours before the oven's scheduled pushing time 
and ensuring that the temperature of each oven is measured and recorded 
at least once every month;
    (2) Recording the time each oven is charged and pushed and 
calculating and recording the net coking time for each oven; and
    (3) Increasing the coking time for each oven that falls below the 
minimum flue temperature trigger established for that oven's coking time 
in the written plan required in Sec.  63.7292(a)(1), assigning the oven 
to the oven-directed program, and recording all relevant information 
according to the requirements in Sec.  63.7292(a)(4) including, but not 
limited to, daily pushing schedules, diagnostic procedures, corrective 
actions, and oven repairs.
    (c) For each non-recovery coke oven battery subject to the work 
practice standards in Sec.  63.7293(a), you must demonstrate continuous 
compliance by maintaining records that document each visual inspection 
of an oven prior to pushing and that the oven was not pushed unless 
there was no smoke in the open space above the coke bed and there was an 
unobstructed view of the door on the opposite side of the oven.
    (d) For each by-product coke oven battery subject to the work 
practice

[[Page 124]]

standard for soaking in Sec.  63.7294(a), you must demonstrate 
continuous compliance by maintaining records that document conformance 
with requirements in Sec.  63.7294(a)(1) through (5).
    (e) For each coke oven battery subject to the work practice standard 
for quenching in Sec.  63.7295(b), you must demonstrate continuous 
compliance according to the requirements of paragraphs (e)(1) through 
(3) of this section:
    (1) Maintaining baffles in each quench tower such that no more than 
5 percent of the cross-sectional area of the tower is uncovered or open 
to the sky as required in Sec.  63.7295(b)(1);
    (2) Maintaining records that document conformance with the washing, 
inspection, and repair requirements in Sec.  63.7295(b)(2), including 
records of the ambient temperature on any day that the baffles were not 
washed; and
    (3) Maintaining records of the source of makeup water to document 
conformance with the requirement for acceptable makeup water in Sec.  
63.7295(a)(2).



Sec.  63.7335  How do I demonstrate continuous compliance with the 
operation and maintenance requirements that apply to me?

    (a) For each by-product coke oven battery, you must demonstrate 
continuous compliance with the operation and maintenance requirements in 
Sec.  63.7300(b) by adhering at all times to the plan requirements and 
recording all information needed to document conformance.
    (b) For each coke oven battery with a capture system or control 
device applied to pushing emissions, you must demonstrate continuous 
compliance with the operation and maintenance requirements in Sec.  
63.7300(c) by meeting the requirements of paragraphs (b)(1) through (3) 
of this section:
    (1) Making monthly inspections of capture systems according to Sec.  
63.7300(c)(1) and recording all information needed to document 
conformance with these requirements;
    (2) Performing preventative maintenance for each control device 
according to Sec.  63.7300(c)(2) and recording all information needed to 
document conformance with these requirements; and
    (3) Initiating and completing corrective action for a bag leak 
detection system alarm according to Sec.  63.7300(c)(3) and recording 
all information needed to document conformance with these requirements. 
This includes records of the times the bag leak detection system alarm 
sounds, and for each valid alarm, the time you initiated corrective 
action, the corrective action(s) taken, and the date on which corrective 
action is completed.
    (c) To demonstrate continuous compliance with the operation and 
maintenance requirements for a baghouse applied to pushing emissions 
from a coke oven battery in Sec.  63.7331(a), you must inspect and 
maintain each baghouse according to the requirements in Sec.  
63.7331(a)(1) through (8) and record all information needed to document 
conformance with these requirements. If you increase or decrease the 
sensitivity of the bag leak detection system beyond the limits specified 
in Sec.  63.7331(a)(6), you must include a copy of the required written 
certification by a responsible official in the next semiannual 
compliance report.
    (d) You must maintain a current copy of the operation and 
maintenance plans required in Sec.  63.7300(b) and (c) onsite and 
available for inspection upon request. You must keep the plans for the 
life of the affected source or until the affected source is no longer 
subject to the requirements of this subpart.



Sec.  63.7336  What other requirements must I meet to demonstrate
continuous compliance?

    (a) Deviations. You must report each instance in which you did not 
meet each emission limitation in this subpart that applies to you. This 
includes periods of startup, shutdown, and malfunction. You must also 
report each instance in which you did not meet each work practice 
standard or operation and maintenance requirement in this subpart that 
applies to you. These instances are deviations from the emission 
limitations (including operating limits), work practice standards, and 
operation and maintenance requirements in this subpart. These deviations 
must be reported according to the requirements in Sec.  63.7341.
    (b) Startup, shutdowns, and malfunctions. (1) Consistent with 
Sec. Sec.  63.6(e) and 63.7(e)(1), deviations that occur during

semiannual monitoring report required by 40 CFR 70.6(a)(3)(iii)(A) or 40 
CFR 71.6(a)(3)(iii)(A), and the compliance report includes all the 
required information concerning deviations from any emission limitation 
or work practice standard in this subpart, submission of the compliance 
report satisfies any obligation to report the same deviations in the 
semiannual monitoring report. However, submission of a compliance report 
does not otherwise affect any obligation you may have to report 
deviations from permit requirements to your permitting authority.

through an open standpipe prior to pushing and ends when the coke begins 
to be pushed from the oven.
    Soaking emissions means the discharge from an open standpipe during 
soaking of visible emissions due to either incomplete coking or leakage 
into the standpipe from the collecting main.
    Standpipe means an apparatus on the oven that provides a passage for 
gases from an oven to the atmosphere when the oven is dampered off the

                        What This Subpart Covers



Sec.  63.7480  What is the purpose of this subpart?

    This subpart establishes national emission limitations and work 
practice standards for hazardous air pollutants (HAP) emitted from 
industrial, commercial, and institutional boilers and process heaters 
located at major sources of HAP. This subpart also establishes 
requirements to demonstrate initial and continuous compliance with the 
emission limitations and work practice standards.



Sec.  63.7485  Am I subject to this subpart?

    You are subject to this subpart if you own or operate an industrial, 
commercial, or institutional boiler or process heater as defined in 
Sec.  63.7575 that is located at, or is part of, a major source of HAP, 
except as specified in Sec.  63.7491. For purposes of this subpart, a 
major source of HAP is as defined in Sec.  63.2, except that for oil and 
natural gas production facilities, a major source of HAP is as defined 
in Sec.  63.7575.

Sec.  63.7500  What emission limitations, work practice standards, and
operating limits must I meet?

    (a) You must meet the requirements in paragraphs (a)(1) through (3) 
of this section, except as provided in paragraphs (b), through (e) of 
this section. You must meet these requirements at all times the affected 
unit is operating, except as provided in paragraph (f) of this section.
    (1) You must meet each emission limit and work practice standard in 
Tables 1 through 3, and 11 through 13 to this subpart that applies to 
your boiler or process heater, for each boiler or process heater at your 
source, except as provided under Sec.  63.7522. The output-based 
emission limits, in units of pounds per million Btu of steam output, in 
Tables 1 or 2 to this subpart are an alternative applicable only to 
boilers and process heaters that generate either steam, cogenerate steam 
with electricity, or both. The output-based emission limits, in units of 
pounds per megawatt-hour, in Tables 1 or 2 to this subpart are an 
alternative applicable

[[Page 134]]

only to boilers that generate only electricity. Boilers that perform 
multiple functions (cogeneration and electricity generation) or supply 
steam to common headers would calculate a total steam energy output 
using equation 21 of Sec.  63.7575 to demonstrate compliance with the 
output-based emission limits, in units of pounds per million Btu of 
steam output, in Tables 1 or 2 to this subpart. If you operate a new 
boiler or process heater, you can choose to comply with alternative 
limits as discussed in paragraphs (a)(1)(i) through (iii) of this 
section, but on or after January 31, 2016, you must comply with the 
emission limits in Table 1 to this subpart.
    (i) If your boiler or process heater commenced construction or 
reconstruction after June 4, 2010 and before May 20, 2011, you may 
comply with the emission limits in Table 1 or 11 to this subpart until 
January 31, 2016.
    (ii) If your boiler or process heater commenced construction or 
reconstruction on or after May 20, 2011 and before December 23, 2011, 
you may comply with the emission limits in Table 1 or 12 to this subpart 
until January 31, 2016.
    (iii) If your boiler or process heater commenced construction or 
reconstruction on or after December 23, 2011 and before April 1, 2013, 
you may comply with the emission limits in Table 1 or 13 to this subpart 
until January 31, 2016.
    (2) You must meet each operating limit in Table 4 to this subpart 
that applies to your boiler or process heater. If you use a control 
device or combination of control devices not covered in Table 4 to this 
subpart, or you wish to establish and monitor an alternative operating 
limit or an alternative monitoring parameter, you must apply to the EPA 
Administrator for approval of alternative monitoring under Sec.  
63.8(f).
    (3) At all times, you must operate and maintain any affected source 
(as defined in Sec.  63.7490), including associated air pollution 
control equipment and monitoring equipment, in a manner consistent with 
safety and good air pollution control practices for minimizing 
emissions. Determination of whether such operation and maintenance 
procedures are being used will be based on information available to the 
Administrator that may include, but is not limited to, monitoring 
results, review of operation and maintenance procedures, review of 
operation and maintenance records, and inspection of the source.
    (b) As provided in Sec.  63.6(g), EPA may approve use of an 
alternative to the work practice standards in this section.
    (c) Limited-use boilers and process heaters must complete a tune-up 
every 5 years as specified in Sec.  63.7540. They are not subject to the 
emission limits in Tables 1 and 2 or 11 through 13 to this subpart, the 
annual tune-up, or the energy assessment requirements in Table 3 to this 
subpart, or the operating limits in Table 4 to this subpart.
    (d) Boilers and process heaters with a heat input capacity of less 
than or equal to 5 million Btu per hour in the units designed to burn 
gas 2 (other) fuels subcategory or units designed to burn light liquid 
fuels subcategory must complete a tune-up every 5 years as specified in 
Sec.  63.7540.
    (e) Boilers and process heaters in the units designed to burn gas 1 
fuels subcategory with a heat input capacity of less than or equal to 5 
million Btu per hour must complete a tune-up every 5 years as specified 
in Sec.  63.7540. Boilers and process heaters in the units designed to 
burn gas 1 fuels subcategory with a heat input capacity greater than 5 
million Btu per hour and less than 10 million Btu per hour must complete 
a tune-up every 2 years as specified in Sec.  63.7540. Boilers and 
process heaters in the units designed to burn gas 1 fuels subcategory 
are not subject to the emission limits in Tables 1 and 2 or 11 through 
13 to this subpart, or the operating limits in Table 4 to this subpart.
    (f) These standards apply at all times the affected unit is 
operating, except during periods of startup and shutdown during which 
time you must comply only with items 5 and 6 of Table 3 to this subpart.

Sec.  63.7501  [Reserved]

                     General Compliance Requirements



Sec.  63.7505  What are my general requirements for complying with 
this subpart?

    (a) You must be in compliance with the emission limits, work 
practice standards, and operating limits in this subpart. These emission 
and operating limits apply to you at all times the affected unit is 
operating except for the periods noted in Sec.  63.7500(f).
    (b) [Reserved]
    (c) You must demonstrate compliance with all applicable emission 
limits using performance stack testing, fuel analysis, or continuous 
monitoring systems (CMS), including a continuous emission monitoring 
system (CEMS), or particulate matter continuous parameter monitoring 
system (PM CPMS), where applicable. You may demonstrate compliance with 
the applicable emission limit for hydrogen chloride (HCl), mercury, or 
total selected metals (TSM) using fuel analysis if the emission rate 
calculated according to Sec.  63.7530(c) is less than the applicable 
emission limit. (For gaseous fuels, you may not use fuel analyses to 
comply with the TSM alternative standard or the HCl standard.) 
Otherwise, you must demonstrate compliance for HCl, mercury, or TSM 
using performance stack testing, if subject to an applicable emission 
limit listed in Tables 1, 2, or 11 through 13 to this subpart.
    (d) If you demonstrate compliance with any applicable emission limit 
through performance testing and subsequent compliance with operating 
limits through the use of CPMS, or with a CEMS or COMS, you must develop 
a site-specific monitoring plan according to the requirements in 
paragraphs (d)(1) through (4) of this section for the use of any CEMS, 
COMS, or CPMS. This requirement also applies to you if you petition the 
EPA Administrator for alternative monitoring parameters under Sec.  
63.8(f).
    (1) For each CMS required in this section (including CEMS, COMS, or 
CPMS), you must develop, and submit to the Administrator for approval 
upon request, a site-specific monitoring plan that addresses design, 
data collection, and the quality assurance and quality control elements 
outlined in Sec.  63.8(d) and the elements described in paragraphs 
(d)(1)(i) through (iii) of this section. You must submit this site-
specific monitoring plan, if requested, at least 60 days before your 
initial performance evaluation of your CMS. This requirement to develop 
and submit a site specific monitoring plan does not apply to affected 
sources with existing CEMS or COMS operated according to the performance 
specifications under appendix B to part 60 of this chapter and that meet 
the requirements of Sec.  63.7525. Using the process described in Sec.  
63.8(f)(4), you may request approval of alternative monitoring system 
quality assurance and quality control procedures in place of those 
specified in this paragraph and, if approved, include the alternatives 
in your site-specific monitoring plan.
    (i) Installation of the CMS sampling probe or other interface at a 
measurement location relative to each affected process unit such that 
the measurement is representative of control of the exhaust emissions 
(e.g., on or downstream of the last control device);
    (ii) Performance and equipment specifications for the sample 
interface, the pollutant concentration or parametric signal analyzer, 
and the data collection and reduction systems; and
    (iii) Performance evaluation procedures and acceptance criteria 
(e.g., calibrations, accuracy audits, analytical drift).
    (2) In your site-specific monitoring plan, you must also address 
paragraphs (d)(2)(i) through (iii) of this section.
    (i) Ongoing operation and maintenance procedures in accordance with 
the general requirements of Sec.  63.8(c)(1)(ii), (c)(3), and 
(c)(4)(ii);
    (ii) Ongoing data quality assurance procedures in accordance with 
the general requirements of Sec.  63.8(d); and
    (iii) Ongoing recordkeeping and reporting procedures in accordance 
with the general requirements of Sec.  63.10(c) (as applicable in Table 
10 to this subpart), (e)(1), and (e)(2)(i).
    (3) You must conduct a performance evaluation of each CMS in 
accordance with your site-specific monitoring plan.

[[Page 136]]

    (4) You must operate and maintain the CMS in continuous operation 
according to the site-specific monitoring plan.
    (e) If you have an applicable emission limit, and you choose to 
comply using definition (2) of ``startup'' in Sec.  63.7575, you must 
develop and implement a written startup and shutdown plan (SSP) 
according to the requirements in Table 3 to this subpart. The SSP must 
be maintained onsite and available upon request for public inspection.

       Testing, Fuel Analyses, and Initial Compliance Requirements



Sec.  63.7510  What are my initial compliance requirements and by what
date must I conduct them?

    (a) For each boiler or process heater that is required or that you 
elect to demonstrate compliance with any of the applicable emission 
limits in Tables 1 or 2 or 11 through 13 of this subpart through 
performance (stack) testing, your initial compliance requirements 
include all the following:
    (1) Conduct performance tests according to Sec.  63.7520 and Table 5 
to this subpart.
    (2) Conduct a fuel analysis for each type of fuel burned in your 
boiler or process heater according to Sec.  63.7521 and Table 6 to this 
subpart, except as specified in paragraphs (a)(2)(i) through (iii) of 
this section.
    (i) For each boiler or process heater that burns a single type of 
fuel, you are not required to conduct a fuel analysis for each type of 
fuel burned in your boiler or process heater according to Sec.  63.7521 
and Table 6 to this subpart. For purposes of this subpart, units that 
use a supplemental fuel only for startup, unit shutdown, and transient 
flame stability purposes still qualify as units that burn a single type 
of fuel, and the supplemental fuel is not subject to the fuel analysis 
requirements under Sec.  63.7521 and Table 6 to this subpart.
    (ii) When natural gas, refinery gas, or other gas 1 fuels are co-
fired with other fuels, you are not required to conduct a fuel analysis 
of those Gas 1 fuels according to Sec.  63.7521 and Table 6 to this 
subpart. If gaseous fuels other than natural gas, refinery gas, or other 
gas 1 fuels are co-fired with other fuels and those non-Gas 1 gaseous 
fuels are subject to another subpart of this part, part 60, part 61, or 
part 65, you are not required to conduct a fuel analysis of those non-
Gas 1 fuels according to Sec.  63.7521 and Table 6 to this subpart.
    (iii) You are not required to conduct a chlorine fuel analysis for 
any gaseous fuels. You must conduct a fuel analysis for mercury on 
gaseous fuels unless the fuel is exempted in paragraphs (a)(2)(i) and 
(ii) of this section.
    (3) Establish operating limits according to Sec.  63.7530 and Table 
7 to this subpart.
    (4) Conduct CMS performance evaluations according to Sec.  63.7525.
    (b) For each boiler or process heater that you elect to demonstrate 
compliance with the applicable emission limits in Tables 1 or 2 or 11 
through 13 to this subpart for HCl, mercury, or TSM through fuel 
analysis, your initial compliance requirement is to conduct a fuel 
analysis for each type of fuel burned in your boiler or process heater 
according to Sec.  63.7521 and Table 6 to this subpart and establish 
operating limits according to Sec.  63.7530 and Table 8 to this subpart. 
The fuels described in paragraph (a)(2)(i) and (ii) of this section are 
exempt from these fuel analysis and operating limit requirements. The 
fuels described in paragraph (a)(2)(ii) of this section are exempt from 
the chloride fuel analysis and operating limit requirements. Boilers and 
process heaters that use a CEMS for mercury or HCl are exempt from the 
performance testing and operating limit requirements specified in 
paragraph (a) of this section for the HAP for which CEMS are used.
    (c) If your boiler or process heater is subject to a carbon monoxide 
(CO) limit, your initial compliance demonstration for CO is to conduct a 
performance test for CO according to Table 5 to this subpart or conduct 
a performance evaluation of your continuous CO monitor, if applicable, 
according to Sec.  63.7525(a). Boilers and process heaters that use a CO 
CEMS to comply with the applicable alternative CO

[[Page 137]]

CEMS emission standard listed in Tables 1, 2, or 11 through 13 to this 
subpart, as specified in Sec.  63.7525(a), are exempt from the initial 
CO performance testing and oxygen concentration operating limit 
requirements specified in paragraph (a) of this section.
    (d) If your boiler or process heater is subject to a PM limit, your 
initial compliance demonstration for PM is to conduct a performance test 
in accordance with Sec.  63.7520 and Table 5 to this subpart.
    (e) For existing affected sources (as defined in Sec.  63.7490), you 
must complete the initial compliance demonstrations, as specified in 
paragraphs (a) through (d) of this section, no later than 180 days after 
the compliance date that is specified for your source in Sec.  63.7495 
and according to the applicable provisions in Sec.  63.7(a)(2) as cited 
in Table 10 to this subpart, except as specified in paragraph (j) of 
this section. You must complete an initial tune-up by following the 
procedures described in Sec.  63.7540(a)(10)(i) through (vi) no later 
than the compliance date specified in Sec.  63.7495, except as specified 
in paragraph (j) of this section. You must complete the one-time energy 
assessment specified in Table 3 to this subpart no later than the 
compliance date specified in Sec.  63.7495.
    (f) For new or reconstructed affected sources (as defined in Sec.  
63.7490), you must complete the initial compliance demonstration with 
the emission limits no later than July 30, 2013 or within 180 days after 
startup of the source, whichever is later. If you are demonstrating 
compliance with an emission limit in Tables 11 through 13 to this 
subpart that is less stringent (that is, higher) than the applicable 
emission limit in Table 1 to this subpart, you must demonstrate 
compliance with the applicable emission limit in Table 1 no later than 
July 29, 2016.
    (g) For new or reconstructed affected sources (as defined in Sec.  
63.7490), you must demonstrate initial compliance with the applicable 
work practice standards in Table 3 to this subpart within the applicable 
annual, biennial, or 5-year schedule as specified in Sec.  63.7515(d) 
following the initial compliance date specified in Sec.  63.7495(a). 
Thereafter, you are required to complete the applicable annual, 
biennial, or 5-year tune-up as specified in Sec.  63.7515(d).
    (h) For affected sources (as defined in Sec.  63.7490) that ceased 
burning solid waste consistent with Sec.  63.7495(e) and for which the 
initial compliance date has passed, you must demonstrate compliance 
within 60 days of the effective date of the waste-to-fuel switch. If you 
have not conducted your compliance demonstration for this subpart within 
the previous 12 months, you must complete all compliance demonstrations 
for this subpart before you commence or recommence combustion of solid 
waste.
    (i) For an existing EGU that becomes subject after January 31, 2016, 
you must demonstrate compliance within 180 days after becoming an 
affected source.
    (j) For existing affected sources (as defined in Sec.  63.7490) that 
have not operated between the effective date of the rule and the 
compliance date that is specified for your source in Sec.  63.7495, you 
must complete the initial compliance demonstration, if subject to the 
emission limits in Table 2 to this subpart, as specified in paragraphs 
(a) through (d) of this section, no later than 180 days after the re-
start of the affected source and according to the applicable provisions 
in Sec.  63.7(a)(2) as cited in Table 10 to this subpart. You must 
complete an initial tune-up by following the procedures described in 
Sec.  63.7540(a)(10)(i) through (vi) no later than 30 days after the re-

Sec.  63.7515  When must I conduct subsequent performance tests, 
fuel analyses, or tune-ups?

    (a) You must conduct all applicable performance tests according to 
Sec.  63.7520 on an annual basis, except as specified in paragraphs (b) 
through (e), (g), and (h) of this section. Annual performance tests must 
be completed no more than 13 months after the previous performance test, 
except as specified in paragraphs (b) through (e), (g), and (h) of this 
section.
    (b) If your performance tests for a given pollutant for at least 2 
consecutive years show that your emissions are at or below 75 percent of 
the emission limit (or, in limited instances as specified in Tables 1 
and 2 or 11 through 13 to this subpart, at or below the emission limit) 
for the pollutant, and if there are no changes in the operation of the 
individual boiler or process heater or air pollution control equipment 
that could increase emissions, you may choose to conduct performance 
tests for the pollutant every third year. Each such performance test 
must be conducted no more than 37 months after the previous performance 
test. If you elect to demonstrate compliance using emission averaging 
under Sec.  63.7522, you must continue to conduct performance tests 
annually. The requirement to test at maximum chloride input level is 
waived unless the stack test is conducted for HCl. The requirement to 
test at maximum mercury input level is waived unless the stack test is 
conducted for mercury. The requirement to test at maximum TSM input 
level is waived unless the stack test is conducted for TSM.
    (c) If a performance test shows emissions exceeded the emission 
limit or 75 percent of the emission limit (as specified in Tables 1 and 
2 or 11 through 13 to this subpart) for a pollutant, you must conduct 
annual performance tests for that pollutant until all performance tests 
over a consecutive 2-year period meet the required level (at or below 75 
percent of the emission limit, as specified in Tables 1 and 2 or 11 
through 13 to this subpart).
    (d) If you are required to meet an applicable tune-up work practice 
standard, you must conduct an annual, biennial, or 5-year performance 
tune-up according to Sec.  63.7540(a)(10), (11), or (12), respectively. 
Each annual tune-up specified in Sec.  63.7540(a)(10) must be no more 
than 13 months after the previous tune-up. Each biennial tune-up 
specified in Sec.  63.7540(a)(11) must be conducted no more than 25 
months after the previous tune-up. Each 5-year tune-up specified in 
Sec.  63.7540(a)(12) must be conducted no more than 61 months after the 
previous tune-up. For a new or reconstructed affected source (as defined 
in Sec.  63.7490), the first annual, biennial, or 5-year tune-up must be 
no later than 13 months, 25 months, or 61 months, respectively, after 
April 1, 2013 or the initial startup of the new or reconstructed 
affected source, whichever is later.
    (e) If you demonstrate compliance with the mercury, HCl, or TSM 
based on fuel analysis, you must conduct a monthly fuel analysis 
according to Sec.  63.7521 for each type of fuel burned that is subject 
to an emission limit in Tables 1, 2, or 11 through 13 to this subpart. 
You may comply with this monthly requirement by completing the fuel 
analysis any time within the calendar month as long as the analysis is 
separated from the previous analysis by at least 14 calendar days. If 
you burn a new type of fuel, you must conduct a fuel analysis before 
burning the new type of fuel in your boiler or process heater. You must 
still meet all applicable continuous compliance requirements in Sec.  
63.7540. If each of 12 consecutive monthly fuel analyses demonstrates 75 
percent or less of the compliance level, you may decrease the fuel 
analysis frequency to quarterly for that fuel. If any quarterly sample 
exceeds 75 percent of the compliance level or you begin burning a new 
type of fuel, you must return to monthly monitoring for that fuel, until 
12 months of fuel analyses are again less than 75 percent of the 
compliance level. If sampling is conducted on one day per month, samples 
should be no less than 14 days apart, but if multiple samples are taken 
per month, the 14-day restriction does not apply.
    (f) You must report the results of performance tests and the 
associated fuel analyses within 60 days after the completion of the 
performance tests. This report must also verify that the

[[Page 139]]

operating limits for each boiler or process heater have not changed or 
provide documentation of revised operating limits established according 
to Sec.  63.7530 and Table 7 to this subpart, as applicable. The reports 
for all subsequent performance tests must include all applicable 
information required in Sec.  63.7550.
    (g) For affected sources (as defined in Sec.  63.7490) that have not 
operated since the previous compliance demonstration and more than one 
year has passed since the previous compliance demonstration, you must 
complete the subsequent compliance demonstration, if subject to the 
emission limits in Tables 1, 2, or 11 through 13 to this subpart, no 
later than 180 days after the re-start of the affected source and 
according to the applicable provisions in Sec.  63.7(a)(2) as cited in 
Table 10 to this subpart. You must complete a subsequent tune-up by 
following the procedures described in Sec.  63.7540(a)(10)(i) through 
(vi) and the schedule described in Sec.  63.7540(a)(13) for units that 
are not operating at the time of their scheduled tune-up.
    (h) If your affected boiler or process heater is in the unit 
designed to burn light liquid subcategory and you combust ultra-low 
sulfur liquid fuel, you do not need to conduct further performance tests 
(stack tests or fuel analyses) if the pollutants measured during the 
initial compliance performance tests meet the emission limits in Tables 
1 or 2 of this subpart providing you demonstrate ongoing compliance with 
the emissions limits by monitoring and recording the type of fuel 
combusted on a monthly basis. If you intend to use a fuel other than 
ultra-low sulfur liquid fuel, natural gas, refinery gas, or other gas 1 
fuel, you must conduct new performance tests within 60 days of burning 
the new fuel type.
    (i) If you operate a CO CEMS that meets the Performance 
Specifications outlined in Sec.  63.7525(a)(3) of this subpart to 
demonstrate compliance with the applicable alternative CO CEMS emission 
standard listed in Tables 1, 2, or 11 through 13 to this subpart, you 
are not required to conduct CO performance tests and are not subject to 
the oxygen concentration operating limit requirement specified in Sec.  
63.7510(a).

Sec.  63.7520  What stack tests and procedures must I use?

    (a) You must conduct all performance tests according to Sec.  
63.7(c), (d), (f), and (h). You must also develop a site-specific stack 
test plan according to the requirements in Sec.  63.7(c). You shall 
conduct all performance tests under such conditions as the Administrator 
specifies to you based on the representative performance of each boiler 
or process heater for the period being tested. Upon request, you shall 
make available to the Administrator such records as may be necessary to 
determine the conditions of the performance tests.
    (b) You must conduct each performance test according to the 
requirements in Table 5 to this subpart.
    (c) You must conduct each performance test under the specific 
conditions listed in Tables 5 and 7 to this subpart. You must conduct 
performance tests at representative operating load conditions while 
burning the type of fuel or mixture of fuels that has the highest 
content of chlorine and mercury, and TSM if you are opting to comply 
with the TSM alternative standard and you must demonstrate initial 
compliance and establish your operating limits based on these 
performance tests. These requirements could result in the need to 
conduct more than one performance test. Following each performance test 
and until the next performance test, you must comply with the operating 
limit for operating load conditions specified in Table 4 to this 
subpart.
    (d) You must conduct a minimum of three separate test runs for each 
performance test required in this section, as specified in Sec.  
63.7(e)(3). Each test run must comply with the minimum applicable 
sampling times or volumes specified in Tables 1 and 2 or 11 through 13 
to this subpart.
    (e) To determine compliance with the emission limits, you must use 
the F-Factor methodology and equations in sections 12.2 and 12.3 of EPA 
Method 19 at 40 CFR part 60, appendix A-7 of this

[[Page 140]]

chapter to convert the measured particulate matter (PM) concentrations, 
the measured HCl concentrations, the measured mercury concentrations, 
and the measured TSM concentrations that result from the performance 
test to pounds per million Btu heat input emission rates.
    (f) Except for a 30-day rolling average based on CEMS (or sorbent 
trap monitoring system) data, if measurement results for any pollutant 
are reported as below the method detection level (e.g., laboratory 
analytical results for one or more sample components are below the 
method defined analytical detection level), you must use the method 
detection level as the measured emissions level for that pollutant in 
calculating compliance. The measured result for a multiple component 
analysis (e.g., analytical values for multiple Method 29 fractions both 
for individual HAP metals and for total HAP metals) may include a 
combination of method detection level data and analytical data reported 
above the method detection level.

emission averaging according to the following procedures and 
requirements in paragraphs (g)(1) through (4) of this section.
    (1) If requested, you must submit the implementation plan no later 
than 180 days before the date that the facility intends to demonstrate 
compliance using the emission averaging option.
    (2) You must include the information contained in paragraphs 
(g)(2)(i) through (vii) of this section in your implementation plan for 
all emission sources included in an emissions average:
    (i) The identification of all existing boilers and process heaters 
in the averaging group, including for each either the applicable HAP 
emission level or the control technology installed as of January 31, 
2013 and the date on which you are requesting emission averaging to

    (ii) The process parameter (heat input or steam generated) that will 
be monitored for each averaging group;
    (iii) The specific control technology or pollution prevention 
measure to be used for each emission boiler or process heater in the 
averaging group and the date of its installation or application. If the 
pollution prevention measure reduces or eliminates emissions from 
multiple boilers or process heaters, the owner or operator must identify

of how the operating limits will be determined;
    (vi) If you request to monitor an alternative operating parameter 
pursuant to Sec.  63.7525, you must also include:
    (A) A description of the parameter(s) to be monitored and an 
explanation of the criteria used to select the parameter(s); and
    (B) A description of the methods and procedures that will be used to 
demonstrate that the parameter indicates proper operation of the control 
device; the frequency and content of monitoring, reporting, and 
recordkeeping requirements; and a demonstration, to the satisfaction of 
the Administrator, that the proposed monitoring frequency is sufficient 
to represent control device operating conditions; and
    (vii) A demonstration that compliance with each of the applicable 
emission limit(s) will be achieved under representative operating load 
conditions. Following each compliance demonstration and until the next 
compliance demonstration, you must comply with the operating limit for 
operating load conditions specified in Table 4 to this subpart.
    (3) If submitted upon request, the Administrator shall review and 
approve or disapprove the plan according to the following criteria:
    (i) Whether the content of the plan includes all of the information 
specified in paragraph (g)(2) of this section; and
    (ii) Whether the plan presents sufficient information to determine 
that compliance will be achieved and maintained.
    (4) The applicable Administrator shall not approve an emission 
averaging implementation plan containing any of the following 
provisions:

[[Page 148]]

    (i) Any averaging between emissions of differing pollutants or 
between differing sources; or
    (ii) The inclusion of any emission source other than an existing 
unit in the same subcategories.
    (h) For a group of two or more existing affected units, each of 
which vents through a single common stack, you may average PM (or TSM), 
HCl, or mercury emissions to demonstrate compliance with the limits for 
that pollutant in Table 2 to this subpart if you satisfy the 
requirements in paragraph (i) or (j) of this section.
    (i) For a group of two or more existing units in the same 
subcategory, each of which vents through a common emissions control 
system to a common stack, that does not receive emissions from units in 
other subcategories or categories, you may treat such averaging group as 
a single existing unit for purposes of this subpart and comply with the 
requirements of this subpart as if the group were a single unit.
    (j) For all other groups of units subject to the common stack 
requirements of paragraph (h) of this section, including situations 
where the exhaust of affected units are each individually controlled and 
then sent to a common stack, the owner or operator may elect to:
    (1) Conduct performance tests according to procedures specified in 
Sec.  63.7520 in the common stack if affected units from other 
subcategories vent to the common stack. The emission limits that the 
group must comply with are determined by the use of Equation 6 of this 
section.

Where:
En = HAP emission limit, pounds per million British thermal units (lb/
          MMBtu) or parts per million (ppm).
Eli = Appropriate emission limit from Table 2 to this subpart for unit 
          i, in units of lb/MMBtu or ppm.
Hi = Heat input from unit i, MMBtu.

    (2) Conduct performance tests according to procedures specified in 
Sec.  63.7520 in the common stack. If affected units and non-affected 
units vent to the common stack, the non-affected units must be shut down 
or vented to a different stack during the performance test unless the 
facility determines to demonstrate compliance with the non-affected 
units venting to the stack; and
    (3) Meet the applicable operating limit specified in Sec.  63.7540 
and Table 8 to this subpart for each emissions control system (except 
that, if each unit venting to the common stack has an applicable opacity 
operating limit, then a single continuous opacity monitoring system may 
be located in the common stack instead of in each duct to the common 
stack).
    (k) The common stack of a group of two or more existing boilers or 
process heaters in the same subcategories subject to paragraph (h) of 
this section may be treated as a separate stack for purposes of 
paragraph (b) of this section and included in an emissions averaging 
group subject to paragraph (b) of this section.

Sec.  63.7525  What are my monitoring, installation, operation, and
maintenance requirements?

    (a) If your boiler or process heater is subject to a CO emission 
limit in Tables 1, 2, or 11 through 13 to this subpart, you must 
install, operate, and maintain an oxygen analyzer system, as defined in 
Sec.  63.7575, or install, certify, operate and maintain continuous 
emission monitoring systems for CO and oxygen (or carbon dioxide 
(CO2)) according to the procedures in paragraphs (a)(1) 
through (6) of this section.
    (1) Install the CO CEMS and oxygen (or CO2) analyzer by 
the compliance date specified in Sec.  63.7495. The CO and oxygen (or 
CO2) levels shall be monitored at the same location at the 
outlet of the boiler or process heater. An

[[Page 149]]

owner or operator may request an alternative test method under Sec.  
63.7 of this chapter, in order that compliance with the CO emissions 
limit be determined using CO2 as a diluent correction in 
place of oxygen at 3 percent. EPA Method 19 F-factors and EPA Method 19 
equations must be used to generate the appropriate CO2 
correction percentage for the fuel type burned in the unit, and must 
also take into account that the 3 percent oxygen correction is to be 
done on a dry basis. The alternative test method request must account 
for any CO2 being added to, or removed from, the emissions 
gas stream as a result of limestone injection, scrubber media, etc.
    (2) To demonstrate compliance with the applicable alternative CO 
CEMS emission standard listed in Tables 1, 2, or 11 through 13 to this 
subpart, you must install, certify, operate, and maintain a CO CEMS and 
an oxygen analyzer according to the applicable procedures under 
Performance Specification 4, 4A, or 4B at 40 CFR part 60, appendix B; 
part 75 of this chapter (if an CO2 analyzer is used); the 
site-specific monitoring plan developed according to Sec.  63.7505(d); 
and the requirements in Sec.  63.7540(a)(8) and paragraph (a) of this 
section. Any boiler or process heater that has a CO CEMS that is 
compliant with Performance Specification 4, 4A, or 4B at 40 CFR part 60, 
appendix B, a site-specific monitoring plan developed according to Sec.  
63.7505(d), and the requirements in Sec.  63.7540(a)(8) and paragraph 
(a) of this section must use the CO CEMS to comply with the applicable 
alternative CO CEMS emission standard listed in Tables 1, 2, or 11 
through 13 to this subpart.
    (i) You must conduct a performance evaluation of each CO CEMS 
according to the requirements in Sec.  63.8(e) and according to 
Performance Specification 4, 4A, or 4B at 40 CFR part 60, appendix B.
    (ii) During each relative accuracy test run of the CO CEMS, you must 
be collect emission data for CO concurrently (or within a 30- to 60-
minute period) by both the CO CEMS and by Method 10, 10A, or 10B at 40 
CFR part 60, appendix A-4. The relative accuracy testing must be at 
representative operating conditions.
    (iii) You must follow the quality assurance procedures (e.g., 
quarterly accuracy determinations and daily calibration drift tests) of 
Procedure 1 of appendix F to part 60. The measurement span value of the 
CO CEMS must be two times the applicable CO emission limit, expressed as 
a concentration.
    (iv) Any CO CEMS that does not comply with Sec.  63.7525(a) cannot 
be used to meet any requirement in this subpart to demonstrate 
compliance with a CO emission limit listed in Tables 1, 2, or 11 through 
13 to this subpart.
    (v) For a new unit, complete the initial performance evaluation no 
later than July 30, 2013, or 180 days after the date of initial startup, 
whichever is later. For an existing unit, complete the initial 
performance evaluation no later than July 29, 2016.
    (vi) When CO2 is used to correct CO emissions and 
CO2 is measured on a wet basis, correct for moisture as 
follows: Install, operate, maintain, and quality assure a continuous 
moisture monitoring system for measuring and recording the moisture 
content of the flue gases, in order to correct the measured hourly 
volumetric flow rates for moisture when calculating CO concentrations. 
The following continuous moisture monitoring systems are acceptable: A 
continuous moisture sensor; an oxygen analyzer (or analyzers) capable of 
measuring O2 both on a wet basis and on a dry basis; or a 
stack temperature sensor and a moisture look-up table, i.e., a 
psychrometric chart (for saturated gas streams following wet scrubbers 
or other demonstrably saturated gas streams, only). The moisture 
monitoring system shall include as a component the automated data 
acquisition and handling system (DAHS) for recording and reporting both 
the raw data (e.g., hourly average wet-and dry basis O2 
values) and the hourly average values of the stack gas moisture content 
derived from those data. When a moisture look-up table is used, the 
moisture monitoring system shall be represented as a single component, 
the certified DAHS, in the monitoring plan for the unit or common stack.

[[Page 150]]

    (3) Complete a minimum of one cycle of CO and oxygen (or 
CO2) CEMS operation (sampling, analyzing, and data recording) 
for each successive 15-minute period. Collect CO and oxygen (or 
CO2) data concurrently. Collect at least four CO and oxygen 
(or CO2) CEMS data values representing the four 15-minute 
periods in an hour, or at least two 15-minute data values during an hour 
when CEMS calibration, quality assurance, or maintenance activities are 
being performed.
    (4) Reduce the CO CEMS data as specified in Sec.  63.8(g)(2).
    (5) Calculate one-hour arithmetic averages, corrected to 3 percent 
oxygen (or corrected to an CO2 percentage determined to be 
equivalent to 3 percent oxygen) from each hour of CO CEMS data in parts 
per million CO concentration. The one-hour arithmetic averages required 
shall be used to calculate the 30-day or 10-day rolling average 
emissions. Use Equation 19-19 in section 12.4.1 of Method 19 of 40 CFR 
part 60, appendix A-7 for calculating the average CO concentration from 
the hourly values.
    (6) For purposes of collecting CO data, operate the CO CEMS as 
specified in Sec.  63.7535(b). You must use all the data collected 
during all periods in calculating data averages and assessing 
compliance, except that you must exclude certain data as specified in 
Sec.  63.7535(c). Periods when CO data are unavailable may constitute 
monitoring deviations as specified in Sec.  63.7535(d).
    (7) Operate an oxygen trim system with the oxygen level set no lower 
than the lowest hourly average oxygen concentration measured during the 
most recent CO performance test as the operating limit for oxygen 
according to Table 7 to this subpart.
    (b) If your boiler or process heater is in the unit designed to burn 
coal/solid fossil fuel subcategory or the unit designed to burn heavy 
liquid subcategory and has an average annual heat input rate greater 
than 250 MMBtu per hour from solid fossil fuel and/or heavy liquid, and 
you demonstrate compliance with the PM limit instead of the alternative 
TSM limit, you must install, maintain, and operate a PM CPMS monitoring 
emissions discharged to the atmosphere and record the output of the 
system as specified in paragraphs (b)(1) through (4) of this section. As 
an alternative to use of a PM CPMS to demonstrate compliance with the PM 
limit, you may choose to use a PM CEMS. If you choose to use a PM CEMS 
to demonstrate compliance with the PM limit instead of the alternative 
TSM limit, you must install, certify, maintain, and operate a PM CEMS 
monitoring emissions discharged to the atmosphere and record the output 
of the system as specified in paragraph (b)(5) through (8) of this 
section. For other boilers or process heaters, you may elect to use a PM 
CPMS or PM CEMS operated in accordance with this section in lieu of 
using other CMS for monitoring PM compliance (e.g., bag leak detectors, 
ESP secondary power, and PM scrubber pressure). Owners of boilers and 
process heaters who elect to comply with the alternative TSM limit are 
not required to install a PM CPMS.
    (1) Install, operate, and maintain your PM CPMS according to the 
procedures in your approved site-specific monitoring plan developed in 
accordance with Sec.  63.7505(d), the requirements in Sec.  
63.7540(a)(9), and paragraphs (b)(1)(i) through (iii) of this section.
    (i) The operating principle of the PM CPMS must be based on in-stack 
or extractive light scatter, light scintillation, beta attenuation, or 
mass accumulation detection of PM in the exhaust gas or representative 
exhaust gas sample. The reportable measurement output from the PM CPMS 
must be expressed as milliamps.
    (ii) The PM CPMS must have a cycle time (i.e., period required to 
complete sampling, measurement, and reporting for each measurement) no 
longer than 60 minutes.
    (iii) The PM CPMS must have a documented detection limit of 0.5 
milligram per actual cubic meter, or less.
    (2) For a new unit, complete the initial performance evaluation no 
later than July 30, 2013, or 180 days after the date of initial startup, 
whichever is later. For an existing unit, complete the initial 
performance evaluation no later than July 29, 2016.
    (3) Collect PM CPMS hourly average output data for all boiler or

hourly average PM CPMS output data collected during all boiler or 
process heater operating hours (milliamps).
    (5) Install, certify, operate, and maintain your PM CEMS according 
to the procedures in your approved site-specific monitoring plan 
developed in accordance with Sec.  63.7505(d), the requirements in Sec.  
63.7540(a)(9), and paragraphs (b)(5)(i) through (iv) of this section.
    (i) You shall conduct a performance evaluation of the PM CEMS 
according to the applicable requirements of Sec.  60.8(e), and 
Performance Specification 11 at 40 CFR part 60, appendix B of this 
chapter.

Performance Specification 11 at 40 CFR part 60, appendix B of this 
chapter, you shall collect PM and oxygen (or carbon dioxide) data 
concurrently (or within a 30-to 60-minute period) by both the CEMS and 
conducting performance tests using Method 5 at 40 CFR part 60, appendix 
A-3 or Method 17 at 40 CFR part 60, appendix A-6 of this chapter.
    (iii) You shall perform quarterly accuracy determinations and daily 
calibration drift tests in accordance with Procedure 2 at 40 CFR part 
60, appendix F of this chapter. You must perform Relative Response 
Audits annually and perform Response Correlation Audits every 3 years.
    (iv) Within 60 days after the date of completing each CEMS relative 
accuracy test audit or performance test conducted to demonstrate 
compliance with this subpart, you must submit the relative accuracy test 
audit data and performance test data to the EPA by successfully 
submitting the data electronically into the EPA's Central Data Exchange 
by using the Electronic Reporting Tool (see http://www.epa.gov/ttn/
chief/ert/erttool.html/).
    (6) For a new unit, complete the initial performance evaluation no 
later than July 30, 2013, or 180 days after the date of initial startup,

    (4) The COMS data must be reduced as specified in Sec.  63.8(g)(2).
    (5) You must include in your site-specific monitoring plan 
procedures and acceptance criteria for operating and maintaining each 
COMS according to the requirements in Sec.  63.8(d). At a minimum, the 
monitoring plan must include a daily calibration drift assessment, a 
quarterly performance audit, and an annual zero alignment audit of each 
COMS.
    (6) You must operate and maintain each COMS according to the 
requirements in the monitoring plan and the requirements of Sec.  
63.8(e). You must identify periods the COMS is out of control including 
any periods that the COMS fails to pass a daily calibration drift 
assessment, a quarterly performance audit, or an annual zero alignment 
audit. Any 6-minute period for which the monitoring system is out of 
control and data are not available for a

[[Page 152]]

required calculation constitutes a deviation from the monitoring 
requirements.
    (7) You must determine and record all the 6-minute averages (and 
daily block averages as applicable) collected for periods during which 
the COMS is not out of control.
    (d) If you have an operating limit that requires the use of a CMS 
other than a PM CPMS or COMS, you must install, operate, and maintain 
each CMS according to the procedures in paragraphs (d)(1) through (5) of 
this section by the compliance date specified in Sec.  63.7495.
    (1) The CPMS must complete a minimum of one cycle of operation every

operation, one representing each of the four 15-minute periods in an 
hour, to have a valid hour of data.
    (2) You must operate the monitoring system as specified in Sec.  
63.7535(b), and comply with the data calculation requirements specified 
in Sec.  63.7535(c).
    (3) Any 15-minute period for which the monitoring system is out-of-
control and data are not available for a required calculation 
constitutes a deviation from the monitoring requirements. Other 
situations that constitute a monitoring deviation are specified in Sec.  
63.7535(d).
    (4) You must determine the 30-day rolling average of all recorded 
readings, except as provided in Sec.  63.7535(c).

test but no less frequently than annually.
    (f) If you have an operating limit that requires the use of a 
pressure monitoring system, you must meet the requirements in paragraphs 
(d) and (f)(1) through (6) of this section.
    (1) Install the pressure sensor(s) in a position that provides a 
representative measurement of the pressure (e.g., PM scrubber pressure

    (2) Minimize or eliminate pulsating pressure, vibration, and 
internal and external corrosion consistent with good engineering 
practices.
    (3) Use a pressure sensor with a minimum tolerance of 1.27 
centimeters of water or a minimum tolerance of 1 percent of the pressure 
monitoring system operating range, whichever is less.
    (4) Perform checks at least once each process operating day to 
ensure pressure measurements are not obstructed (e.g., check for 
pressure tap pluggage daily).
    (5) Conduct a performance evaluation of the pressure monitoring 
system in accordance with your monitoring plan at the time of each 
performance test but no less frequently than annually.
    (6) If at any time the measured pressure exceeds the manufacturer's

weigh hopper, or hopper flow measurement device), you must meet the 
requirements in paragraphs (d) and (i)(1) through (2) of this section.
    (1) Install the system in a position(s) that provides a 
representative measurement of the total sorbent injection rate.
    (2) Conduct a performance evaluation of the sorbent injection rate 
monitoring system in accordance with your monitoring plan at the time of 
each performance test but no less frequently than annually.
    (j) If you are not required to use a PM CPMS and elect to use a 
fabric filter bag leak detection system to comply with the requirements 
of this subpart, you must install, calibrate, maintain, and continuously 
operate the bag leak detection system as specified in paragraphs (j)(1) 
through (6) of this section.
    (1) You must install a bag leak detection sensor(s) in a position(s)

instrumentation and alert may be shared among detectors.
    (k) For each unit that meets the definition of limited-use boiler or 
process heater, you must keep fuel use records for the days the boiler 
or process heater was operating.
    (l) For each unit for which you decide to demonstrate compliance 
with the mercury or HCl emissions limits in Tables 1 or 2 or 11 through 
13 of this subpart by use of a CEMS for mercury or HCl, you must 
install, certify, maintain, and operate a CEMS measuring emissions 
discharged to the atmosphere and record the output of the system as 
specified in paragraphs (l)(1) through (8) of this section. For HCl, 
this option for an affected unit takes effect on the date a final 
performance specification for a HCl CEMS is published in the Federal 
Register or the date of approval of a site-specific monitoring plan.
    (1) Notify the Administrator one month before starting use of the

[[Page 154]]

CEMS, and notify the Administrator one month before stopping use of the 
CEMS.
    (2) Each CEMS shall be installed, certified, operated, and

    (5) Compliance with the applicable emissions limit shall be 
determined based on the 30-day rolling average of the hourly arithmetic 
average emissions rates using the continuous monitoring system outlet 
data. The 30-day rolling arithmetic average emission rate (lb/MMBtu) 
shall be calculated using the equations in EPA Reference Method 19 at 40 
CFR part 60, appendix A-7, but substituting the mercury or HCl 
concentration for the pollutant concentrations normally used in Method 
19.
    (6) Collect CEMS hourly averages for all operating hours on a 30-day 
rolling average basis. Collect at least four CMS data values 
representing the four 15-minute periods in an hour, or at least two 15-
minute data values during an hour when CMS calibration, quality 
assurance, or maintenance activities are being performed.
    (7) The one-hour arithmetic averages required shall be expressed in 
lb/MMBtu and shall be used to calculate the boiler 30-day and 10-day 
rolling average emissions.
    (8) You are allowed to substitute the use of the PM, mercury or HCl 
CEMS for the applicable fuel analysis, annual performance test, and 
operating limits specified in Table 4 to this subpart to demonstrate 
compliance with the PM, mercury or HCl emissions limit, and if you are 
using an acid gas wet scrubber or dry sorbent injection control 
technology to comply with the HCl emission limit, you are allowed to 
substitute the use of a sulfur dioxide (SO2) CEMS for the 
applicable fuel analysis, annual performance test, and operating limits 
specified in Table 4 to this subpart to demonstrate compliance with HCl 
emissions limit.
    (m) If your unit is subject to a HCl emission limit in Tables 1, 2, 
or 11 through 13 of this subpart and you have an acid gas wet scrubber 
or dry sorbent injection control technology and you elect to use an 
SO2 CEMS to demonstrate continuous compliance with the HCl 
emission limit, you must install the monitor at the outlet of the boiler 
or process heater, downstream of all emission control devices, and you 
must install, certify, operate, and maintain the CEMS according to 
either part 60 or part 75 of this chapter.
    (1) The SO2 CEMS must be installed by the compliance date 
specified in Sec.  63.7495.
    (2) For on-going quality assurance (QA), the SO2 CEMS

Procedure 1 of appendix F of part 60 or the applicable daily, quarterly, 
and semiannual or annual requirements in sections 2.1 through 2.3 of 
appendix B to part 75 of this chapter, with the following addition: You 
must perform the linearity checks required in section 2.2 of appendix B 
to part 75 of this chapter if the SO2 CEMS has a span value 
of 30 ppm or less.
    (3) For a new unit, the initial performance evaluation shall be 
completed no later than July 30, 2013, or 180 days after the date of 
initial startup, whichever is later. For an existing unit, the initial 
performance evaluation shall be completed no later than July 29, 2016.
    (4) For purposes of collecting SO2 data, you must operate 
the SO2 CEMS

[[Page 155]]

as specified in Sec.  63.7535(b). You must use all the data collected 
during all periods in calculating data averages and assessing 
compliance, except that you must exclude certain data as specified in 
Sec.  63.7535(c). Periods when SO2 data are unavailable may 
constitute monitoring deviations as specified in Sec.  63.7535(d).
    (5) Collect CEMS hourly averages for all operating hours on a 30-day 
rolling average basis.
    (6) Use only unadjusted, quality-assured SO2 
concentration values in the emissions calculations; do not apply bias 
adjustment factors to the part 75 SO2 data and do not use 
part 75 substitute data values.

Sec.  63.7530  How do I demonstrate initial compliance with the emission
limitations, fuel specifications and work practice standards?

    (a) You must demonstrate initial compliance with each emission limit 
that applies to you by conducting initial performance tests and fuel 
analyses and establishing operating limits, as applicable, according to 
Sec.  63.7520, paragraphs (b) and (c) of this section, and Tables 5 and 
7 to this subpart. The requirement to conduct a fuel analysis is not 
applicable for units that burn a single type of fuel, as specified by 
Sec.  63.7510(a)(2). If applicable, you must also install, operate, and 
maintain all applicable CMS (including CEMS, COMS, and CPMS) according 
to Sec.  63.7525.
    (b) If you demonstrate compliance through performance stack testing, 
you must establish each site-specific operating limit in Table 4 to this 
subpart that applies to you according to the requirements in Sec.  
63.7520, Table 7 to this subpart, and paragraph (b)(4) of this section, 
as applicable. You must also conduct fuel analyses according to Sec.  
63.7521 and establish maximum fuel pollutant input levels according to 
paragraphs (b)(1) through (3) of this section, as applicable, and as 
specified in Sec.  63.7510(a)(2). (Note that Sec.  63.7510(a)(2) exempts 
certain fuels from the fuel analysis requirements.) However, if you 
switch fuel(s) and cannot show that the new fuel(s) does (do) not 
increase the chlorine, mercury, or TSM input into the unit through the 
results of fuel analysis, then you must repeat the performance test to 
demonstrate compliance while burning the new fuel(s).
    (1) You must establish the maximum chlorine fuel input (Clinput) 
during the initial fuel analysis according to the procedures in 
paragraphs (b)(1)(i) through (iii) of this section.
    (i) You must determine the fuel type or fuel mixture that you could 
burn in your boiler or process heater that has the highest content of 
chlorine.
    (ii) During the fuel analysis for hydrogen chloride, you must 
determine the fraction of the total heat input for each fuel type burned 
(Qi) based on the fuel mixture that has the highest content of chlorine, 
and the average chlorine concentration of each fuel type burned (Ci).
    (iii) You must establish a maximum chlorine input level using 
Equation 7 of this section.
[GRAPHIC] [TIFF OMITTED] TR21MR11.006


Where:

Clinput = Maximum amount of chlorine entering the boiler or process 
          heater through fuels burned in units of pounds per million 
          Btu.
Ci = Arithmetic average concentration of chlorine in fuel type, i, 
          analyzed according to Sec.  63.7521, in units of pounds per 
          million Btu.
Qi = Fraction of total heat input from fuel type, i, based on the fuel 
          mixture that has the highest content of chlorine during the 
          initial compliance test. If you do not burn multiple fuel 
          types during the performance testing, it is not necessary

[[Page 156]]

          to determine the value of this term. Insert a value of ``1'' 
          for Qi. For continuous compliance demonstration, the actual 
          fraction of the fuel burned during the month should be used.
n = Number of different fuel types burned in your boiler or process 
          heater for the mixture that has the highest content of 
          chlorine.

    (2) You must establish the maximum mercury fuel input level 
(Mercuryinput) during the initial fuel analysis using the procedures in 
paragraphs (b)(2)(i) through (iii) of this section.
    (i) You must determine the fuel type or fuel mixture that you could 
burn in your boiler or process heater that has the highest content of 
mercury.
    (ii) During the compliance demonstration for mercury, you must 
determine the fraction of total heat input for each fuel burned (Qi) 
based on the fuel mixture that has the highest content of mercury, and 
the average mercury concentration of each fuel type burned (HGi).
    (iii) You must establish a maximum mercury input level using 
Equation 8 of this section.
[GRAPHIC] [TIFF OMITTED] TR21MR11.007


Where:

Mercuryinput = Maximum amount of mercury entering the boiler or process 
          heater through fuels burned in units of pounds per million 
          Btu.
HGi = Arithmetic average concentration of mercury in fuel type, i, 
          analyzed according to Sec.  63.7521, in units of pounds per 
          million Btu.
Qi = Fraction of total heat input from fuel type, i, based on the fuel 
          mixture that has the highest mercury content during the 
          initial compliance test. If you do not burn multiple fuel 
          types during the performance test, it is not necessary to 
          determine the value of this term. Insert a value of ``1'' for 
          Qi. For continuous compliance demonstration, the actual 
          fraction of the fuel burned during the month should be used.
n = Number of different fuel types burned in your boiler or process 
          heater for the mixture that has the highest content of 
          mercury.

    (3) If you opt to comply with the alternative TSM limit, you must 
establish the maximum TSM fuel input (TSMinput) for solid or liquid 
fuels during the initial fuel analysis according to the procedures in 
paragraphs (b)(3)(i) through (iii) of this section.
    (i) You must determine the fuel type or fuel mixture that you could 
burn in your boiler or process heater that has the highest content of 
TSM.
    (ii) During the fuel analysis for TSM, you must determine the 
fraction of the total heat input for each fuel type burned (Qi) based on 
the fuel mixture that has the highest content of TSM, and the average 
TSM concentration of each fuel type burned (TSMi).
    (iii) You must establish a maximum TSM input level using Equation 9 
of this section.
[GRAPHIC] [TIFF OMITTED] TR31JA13.013

Where:

TSMinput = Maximum amount of TSM entering the boiler or process heater 
          through fuels burned in units of pounds per million Btu.
TSMi = Arithmetic average concentration of TSM in fuel type, i, analyzed 
          according to Sec.  63.7521, in units of pounds per million 
          Btu.
Qi = Fraction of total heat input from fuel type, i, based on the fuel 
          mixture that has the highest content of TSM during the initial 
          compliance test. If you do not burn multiple fuel types during 
          the performance testing, it is not necessary to

[[Page 157]]

          determine the value of this term. Insert a value of ``1'' for 
          Qi. For continuous compliance demonstration, the actual 
          fraction of the fuel burned during the month should be used.
n = Number of different fuel types burned in your boiler or process 
          heater for the mixture that has the highest content of TSM.

    (4) You must establish parameter operating limits according to 
paragraphs (b)(4)(i) through (ix) of this section. As indicated in Table 
4 to this subpart, you are not required to establish and comply with the 
operating parameter limits when you are using a CEMS to monitor and 
demonstrate compliance with the applicable emission limit for that 
control device parameter.
    (i) For a wet acid gas scrubber, you must establish the minimum 
scrubber effluent pH and liquid flow rate as defined in Sec.  63.7575, 
as your operating limits during the performance test during which you 
demonstrate compliance with your applicable limit. If you use a wet 
scrubber and you conduct separate performance tests for HCl and mercury 
emissions, you must establish one set of minimum scrubber effluent pH, 
liquid flow rate, and pressure drop operating limits. The minimum 
scrubber effluent pH operating limit must be established during the HCl 
performance test. If you conduct multiple performance tests, you must 
set the minimum liquid flow rate operating limit at the higher of the 
minimum values established during the performance tests.
    (ii) For any particulate control device (e.g., ESP, particulate wet 
scrubber, fabric filter) for which you use a PM CPMS, you must establish 
your PM CPMS operating limit and determine compliance with it according 
to paragraphs (b)(4)(ii)(A) through (F) of this section.
    (A) Determine your operating limit as the average PM CPMS output 
value recorded during the most recent performance test run demonstrating 
compliance with the filterable PM emission limit or at the PM CPMS 
output value corresponding to 75 percent of the emission limit if your 
PM performance test demonstrates compliance below 75 percent of the 
emission limit. You must verify an existing or establish a new operating 
limit after each repeated performance test. You must repeat the 
performance test annually and reassess and adjust the site-specific 
operating limit in accordance with the results of the performance test.
    (1) Your PM CPMS must provide a 4-20 milliamp output and the 
establishment of its relationship to manual reference method 
measurements must be determined in units of milliamps.
    (2) Your PM CPMS operating range must be capable of reading PM 
concentrations from zero to a level equivalent to at least two times 
your allowable emission limit. If your PM CPMS is an auto-ranging 
instrument capable of multiple scales, the primary range of the 
instrument must be capable of reading PM concentration from zero to a 
level equivalent to two times your allowable emission limit.
    (3) During the initial performance test or any such subsequent 
performance test that demonstrates compliance with the PM limit, record 
and average all milliamp output values from the PM CPMS for the periods 
corresponding to the compliance test runs (e.g., average all your PM 
CPMS output values for three corresponding 2-hour Method 5I test runs).
    (B) If the average of your three PM performance test runs are below 
75 percent of your PM emission limit, you must calculate an operating 
limit by establishing a relationship of PM CPMS signal to PM 
concentration using the PM CPMS instrument zero, the average PM CPMS 
values corresponding to the three compliance test runs, and the average 
PM concentration from the Method 5 or performance test with the 
procedures in paragraphs (b)(4)(ii)(B)(1) through (4) of this section.
    (1) Determine your instrument zero output with one of the following 
procedures:
    (i) Zero point data for in-situ instruments should be obtained by 
removing the instrument from the stack and monitoring ambient air on a 
test bench.
    (ii) Zero point data for extractive instruments should be obtained 
by removing the extractive probe from the stack and drawing in clean 
ambient air.
    (iii) The zero point may also be established by performing manual 
reference

[[Page 158]]

method measurements when the flue gas is free of PM emissions or 
contains very low PM concentrations (e.g., when your process is not 
operating, but the fans are operating or your source is combusting only 
natural gas) and plotting these with the compliance data to find the 
zero intercept.
    (iv) If none of the steps in paragraphs (b)(4)(ii)(B)(1)(i) through 
(iii) of this section are possible, you must use a zero output value 
provided by the manufacturer.
    (2) Determine your PM CPMS instrument average in milliamps, and the 
average of your corresponding three PM compliance test runs, using 
equation 10.
[GRAPHIC] [TIFF OMITTED] TR31JA13.014

Where:

X1 = the PM CPMS data points for the three runs constituting 
          the performance test,
Y1 = the PM concentration value for the three runs 
          constituting the performance test, and
n = the number of data points.

    (3) With your instrument zero expressed in milliamps, your three run 
average PM CPMS milliamp value, and your three run average PM 
concentration from your three compliance tests, determine a relationship 
of lb/MMBtu per milliamp with equation 11.
[GRAPHIC] [TIFF OMITTED] TR31JA13.015

Where:

R = the relative lb/MMBtu per milliamp for your PM CPMS,
Y1 = the three run average lb/MMBtu PM concentration,
X1 = the three run average milliamp output from you PM CPMS, 
          and
z = the milliamp equivalent of your instrument zero determined from 
          (B)(i).

    (4) Determine your source specific 30-day rolling average operating 
limit using the lb/MMBtu per milliamp value from Equation 11 in equation 
12, below. This sets your operating limit at the PM CPMS output value 
corresponding to 75 percent of your emission limit.
[GRAPHIC] [TIFF OMITTED] TR31JA13.016

Where:

Ol = the operating limit for your PM CPMS on a 30-day rolling 
          average, in milliamps.
L = your source emission limit expressed in lb/MMBtu,
z = your instrument zero in milliamps, determined from (B)(i), and
R = the relative lb/MMBtu per milliamp for your PM CPMS, from Equation 
          11.

    (C) If the average of your three PM compliance test runs is at or 
above 75 percent of your PM emission limit you must determine your 30-
day rolling average operating limit by averaging the PM CPMS milliamp 
output corresponding to your three PM performance test runs that 
demonstrate compliance with the emission limit using equation 13 and you 
must submit all compliance test and PM CPMS data according to the 
reporting requirements

[[Page 159]]

in paragraph (b)(4)(ii)(F) of this section.
[GRAPHIC] [TIFF OMITTED] TR31JA13.017

Where:

X1 = the PM CPMS data points for all runs i,
n = the number of data points, and
Oh = your site specific operating limit, in milliamps.

    (D) To determine continuous compliance, you must record the PM CPMS 
output data for all periods when the process is operating and the PM 
CPMS is not out-of-control. You must demonstrate continuous compliance 
by using all quality-assured hourly average data collected by the PM 
CPMS for all operating hours to calculate the arithmetic average 
operating parameter in units of the operating limit (milliamps) on a 30-
day rolling average basis, updated at the end of each new operating 
hour. Use Equation 14 to determine the 30-day rolling average.
[GRAPHIC] [TIFF OMITTED] TR31JA13.018

Where:

30-day = 30-day average.
Hpvi = is the hourly parameter value for hour i
n = is the number of valid hourly parameter values collected over the 
          previous 30 operating days.

    (E) Use EPA Method 5 of appendix A to part 60 of this chapter to 
determine PM emissions. For each performance test, conduct three 
separate runs under the conditions that exist when the affected source 
is operating at the highest load or capacity level reasonably expected 
to occur. Conduct each test run to collect a minimum sample volume 
specified in Tables 1, 2, or 11 through 13 to this subpart, as 
applicable, for determining compliance with a new source limit or an 
existing source limit. Calculate the average of the results from three 
runs to determine compliance. You need not determine the PM collected in 
the impingers (``back half'') of the Method 5 particulate sampling train 
to demonstrate compliance with the PM standards of this subpart. This 
shall not preclude the permitting authority from requiring a 
determination of the ``back half'' for other purposes.
    (F) For PM performance test reports used to set a PM CPMS operating 
limit, the electronic submission of the test report must also include 
the make and model of the PM CPMS instrument, serial number of the 
instrument, analytical principle of the instrument (e.g. beta 
attenuation), span of the instruments primary analytical range, milliamp 
value equivalent to the instrument zero output, technique by which this 
zero value was determined, and the average milliamp signals 
corresponding to each PM compliance test run.
    (iii) For a particulate wet scrubber, you must establish the minimum 
pressure drop and liquid flow rate as defined in Sec.  63.7575, as your 
operating limits during the three-run performance test during which you 
demonstrate compliance with your applicable limit. If you use a wet 
scrubber and you conduct separate performance tests for PM and TSM 
emissions, you must establish

[[Page 160]]

one set of minimum scrubber liquid flow rate and pressure drop operating 
limits. The minimum scrubber effluent pH operating limit must be 
established during the HCl performance test. If you conduct multiple 
performance tests, you must set the minimum liquid flow rate and 
pressure drop operating limits at the higher of the minimum values 
established during the performance tests.
    (iv) For an electrostatic precipitator (ESP) operated with a wet 
scrubber, you must establish the minimum total secondary electric power 
input, as defined in Sec.  63.7575, as your operating limit during the 
three-run performance test during which you demonstrate compliance with 
your applicable limit. (These operating limits do not apply to ESP that 
are operated as dry controls without a wet scrubber.)
    (v) For a dry scrubber, you must establish the minimum sorbent 
injection rate for each sorbent, as defined in Sec.  63.7575, as your 
operating limit during the three-run performance test during which you 
demonstrate compliance with your applicable limit.
    (vi) For activated carbon injection, you must establish the minimum 
activated carbon injection rate, as defined in Sec.  63.7575, as your 
operating limit during the three-run performance test during which you 
demonstrate compliance with your applicable limit.
    (vii) The operating limit for boilers or process heaters with fabric 
filters that demonstrate continuous compliance through bag leak 
detection systems is that a bag leak detection system be installed 
according to the requirements in Sec.  63.7525, and that each fabric 
filter must be operated such that the bag leak detection system alert is 
not activated more than 5 percent of the operating time during a 6-month 
period.
    (viii) For a minimum oxygen level, if you conduct multiple 
performance tests, you must set the minimum oxygen level at the lower of 
the minimum values established during the performance tests.
    (ix) The operating limit for boilers or process heaters that 
demonstrate continuous compliance with the HCl emission limit using a 
SO2 CEMS is to install and operate the SO2 
according to the requirements in Sec.  63.7525(m) establish a maximum 
SO2 emission rate equal to the highest hourly average 
SO2 measurement during the most recent three-run performance 
test for HCl.
    (c) If you elect to demonstrate compliance with an applicable 
emission limit through fuel analysis, you must conduct fuel analyses 
according to Sec.  63.7521 and follow the procedures in paragraphs 
(c)(1) through (5) of this section.
    (1) If you burn more than one fuel type, you must determine the fuel 
mixture you could burn in your boiler or process heater that would 
result in the maximum emission rates of the pollutants that you elect to 
demonstrate compliance through fuel analysis.
    (2) You must determine the 90th percentile confidence level fuel 
pollutant concentration of the composite samples analyzed for each fuel 
type using the one-sided t-statistic test described in Equation 15 of 
this section.
[GRAPHIC] [TIFF OMITTED] TR31JA13.019

Where:

P90 = 90th percentile confidence level pollutant concentration, in 
          pounds per million Btu.
Mean = Arithmetic average of the fuel pollutant concentration in the 
          fuel samples analyzed according to Sec.  63.7521, in units of 
          pounds per million Btu.
SD = Standard deviation of the mean of pollutant concentration in the 
          fuel samples analyzed according to Sec.  63.7521, in units of 
          pounds per million Btu. SD is calculated as the sample

          according to Equation 15 of this section.
Qi = Fraction of total heat input from fuel type, i, based on the fuel 
          mixture that has the highest mercury content. If you do not 
          burn multiple fuel types, it is not necessary to determine the 
          value of this term. Insert a value of ``1'' for Qi. For 
          continuous compliance demonstration, the actual fraction of 
          the fuel burned during the month should be used.

          heater for the mixture that has the highest TSM content.

    (d)[Reserved]
    (e) You must include with the Notification of Compliance Status a 
signed certification that either the energy assessment was completed 
according to Table 3 to this subpart, and that the assessment is an 
accurate depiction of your facility at the time of the assessment, or 
that the maximum number of on-site technical hours specified in the 
definition of energy assessment applicable to the facility has been 
expended.
    (f) You must submit the Notification of Compliance Status containing 
the results of the initial compliance demonstration according to the 
requirements in Sec.  63.7545(e).
    (g) If you elect to demonstrate that a gaseous fuel meets the 
specifications of another gas 1 fuel as defined in Sec.  63.7575, you 
must conduct an initial fuel specification analyses according to Sec.  
63.7521(f) through (i) and according to the frequency listed in Sec.  
63.7540(c) and maintain records of the results of the testing as 
outlined in Sec.  63.7555(g). For samples where the initial mercury

operating limit in Tables 4 and 8 to this subpart, you may do so only if 
your affected boiler or process heater:
    (1) Has a system using wet scrubber or dry sorbent injection and 
SO2 CEMS installed on the unit; and
    (2) At all times, you operate the wet scrubber or dry sorbent 
injection for acid gas control on the unit consistent with Sec.  
63.7500(a)(3); and
    (3) You establish a unit-specific maximum SO2 operating 
limit by collecting the maximum hourly SO2 emission rate on 
the SO2 CEMS during the paired 3-run test for HCl. The 
maximum SO2 operating limit is equal to the highest hourly 
average SO2 concentration measured during the HCl performance 
test.

Sec.  63.7533  Can I use efficiency credits earned from implementation
of energy conservation measures to comply with this subpart?

    (a) If you elect to comply with the alternative equivalent output-
based emission limits, instead of the heat input-based limits listed in 
Table 2 to this subpart, and you want to take credit for implementing 
energy conservation measures identified in an energy assessment, you may 
demonstrate compliance using efficiency credits according to the 
procedures in this section. You may use this compliance approach for an 
existing affected boiler for demonstrating initial compliance according 
to Sec.  63.7522(e) and for demonstrating monthly compliance according 
to Sec.  63.7522(f). Owners or operators using this compliance approach 
must establish an emissions benchmark, calculate and document the 
efficiency credits, develop an Implementation Plan, comply with the 
general reporting requirements, and apply the efficiency credit 
according to the procedures in paragraphs (b) through (f) of this 
section. You cannot use this compliance approach for a new or 
reconstructed affected boiler. Additional guidance from the Department 
of Energy on efficiency credits is available at: http://www.epa.gov/ttn/
atw/boiler/boilerpg.html.

[[Page 163]]

    (b) For each existing affected boiler for which you intend to apply 
emissions credits, establish a benchmark from which emission reduction 
credits may be generated by determining the actual annual fuel heat 
input to the affected boiler before initiation of an energy conservation 
activity to reduce energy demand (i.e., fuel usage) according to 
paragraphs (b)(1) through (4) of this section. The benchmark shall be 
expressed in trillion Btu per year heat input.
    (1) The benchmark from which efficiency credits may be generated 
shall be determined by using the most representative, accurate, and 
reliable process available for the source. The benchmark shall be 
established for a one-year period before the date that an energy demand 
reduction occurs, unless it can be demonstrated that a different time 
period is more representative of historical operations.
    (2) Determine the starting point from which to measure progress. 
Inventory all fuel purchased and generated on-site (off-gases, residues) 
in physical units (MMBtu, million cubic feet, etc.).
    (3) Document all uses of energy from the affected boiler. Use the 
most recent data available.
    (4) Collect non-energy related facility and operational data to 
normalize, if necessary, the benchmark to current operations, such as 
building size, operating hours, etc. If possible, use actual data that 
are current and timely rather than estimated data.
    (c) Efficiency credits can be generated if the energy conservation 
measures were implemented after January 1, 2008 and if sufficient 
information is available to determine the appropriate value of credits.
    (1) The following emission points cannot be used to generate 
efficiency credits:
    (i) Energy conservation measures implemented on or before January 1, 
2008, unless the level of energy demand reduction is increased after 
January 1, 2008, in which case credit will be allowed only for change in 
demand reduction achieved after January 1, 2008.
    (ii) Efficiency credits on shut-down boilers. Boilers that are shut 
down cannot be used to generate credits unless the facility provides 
documentation linking the permanent shutdown to energy conservation 
measures identified in the energy assessment. In this case, the bench 
established for the affected boiler to which the credits from the 
shutdown will be applied must be revised to include the benchmark 
established for the shutdown boiler.
    (2) For all points included in calculating emissions credits, the 
owner or operator shall:
    (i) Calculate annual credits for all energy demand points. Use 
Equation 19 to calculate credits. Energy conservation measures that meet 
the criteria of paragraph (c)(1) of this section shall not be included, 
except as specified in paragraph (c)(1)(i) of this section.
    (3) Credits are generated by the difference between the benchmark 
that is established for each affected boiler, and the actual energy 
demand reductions from energy conservation measures implemented after 
January 1, 2008. Credits shall be calculated using Equation 19 of this 
section as follows:
    (i) The overall equation for calculating credits is:
    [GRAPHIC] [TIFF OMITTED] TR31JA13.023
    
Where:

ECredits = Energy Input Savings for all energy conservation measures 
          implemented for an affected boiler, expressed as a decimal 
          fraction of the baseline energy input.
EISiactual = Energy Input Savings for each energy 
          conservation measure, i, implemented for an affected boiler, 
          million Btu per year.
EIbaseline = Energy Input baseline for the affected boiler, 
          million Btu per year.

[[Page 164]]

n = Number of energy conservation measures included in the efficiency 
          credit for the affected boiler.

    (ii) [Reserved]
    (d) The owner or operator shall develop, and submit for approval 
upon request by the Administrator, an Implementation Plan containing all 
of the information required in this paragraph for all boilers to be 
included in an efficiency credit approach. The Implementation Plan shall 
identify all existing affected boilers to be included in applying the 
efficiency credits. The Implementation Plan shall include a description 
of the energy conservation measures implemented and the energy savings 
generated from each measure and an explanation of the criteria used for 
determining that savings. If requested, you must submit the 
implementation plan for efficiency credits to the Administrator for 
review and approval no later than 180 days before the date on which the 
facility intends to demonstrate compliance using the efficiency credit 
approach.
    (e) The emissions rate as calculated using Equation 20 of this 
section from each existing boiler participating in the efficiency credit 
option must be in compliance with the limits in Table 2 to this subpart 
at all times the affected unit is subject to numeric emission limits, 
following the compliance date specified in Sec.  63.7495.
    (f) You must use Equation 20 of this section to demonstrate initial 
compliance by demonstrating that the emissions from the affected boiler 
participating in the efficiency credit compliance approach do not exceed 
the emission limits in Table 2 to this subpart.
[GRAPHIC] [TIFF OMITTED] TR31JA13.024

Where:

Eadj = Emission level adjusted by applying the efficiency 
          credits earned, lb per million Btu steam output (or lb per 
          MWh) for the affected boiler.
Em = Emissions measured during the performance test, lb per 
          million Btu steam output (or lb per MWh) for the affected 
          boiler.
ECredits = Efficiency credits from Equation 19 for the affected boiler.

    (g) As part of each compliance report submitted as required under 
Sec.  63.7550, you must include documentation that the energy 
conservation measures implemented continue to generate the credit for 
use in demonstrating compliance with the emission limits.

                   Continuous Compliance Requirements



Sec.  63.7535  Is there a minimum amount of monitoring data I must obtain?

    (a) You must monitor and collect data according to this section and 
the site-specific monitoring plan required by Sec.  63.7505(d).
    (b) You must operate the monitoring system and collect data at all 
required intervals at all times that each boiler or process heater is 
operating and compliance is required, except for periods of monitoring 
system malfunctions or out of control periods (see Sec.  63.8(c)(7) of 
this part), and required monitoring system quality assurance or control 
activities, including, as applicable, calibration checks, required zero 
and span adjustments, and scheduled CMS maintenance as defined in your 
site-specific monitoring plan. A monitoring system malfunction is any 
sudden, infrequent, not reasonably preventable failure of the monitoring 
system to provide valid data. Monitoring system failures that are caused 
in part by poor maintenance or careless operation are not malfunctions. 
You are required to complete monitoring system repairs in response to 
monitoring system malfunctions or out-of-control periods and to return 
the monitoring system to operation as expeditiously as practicable.
    (c) You may not use data recorded during periods of startup and 
shutdown, monitoring system malfunctions or out-of-control periods, 
repairs associated with monitoring system malfunctions or out-of-control 
periods, or

[[Page 165]]

required monitoring system quality assurance or control activities in 
data averages and calculations used to report emissions or operating 
levels. You must record and make available upon request results of CMS 
performance audits and dates and duration of periods when the CMS is out 
of control to completion of the corrective actions necessary to return 
the CMS to operation consistent with your site-specific monitoring plan. 
You must use all the data collected during all other periods in 
assessing compliance and the operation of the control device and 
associated control system.
    (d) Except for periods of monitoring system malfunctions, repairs 
associated with monitoring system malfunctions, and required monitoring 
system quality assurance or quality control activities (including, as 
applicable, system accuracy audits, calibration checks, and required 
zero and span adjustments), failure to collect required data is a 
deviation of the monitoring requirements. In calculating monitoring 
results, do not use any data collected during periods of startup and 
shutdown, when the monitoring system is out of control as specified in 
your site-specific monitoring plan, while conducting repairs associated 
with periods when the monitoring system is out of control, or while 
conducting required monitoring system quality assurance or quality 
control activities. You must calculate monitoring results using all 
other monitoring data collected while the process is operating. You must 
report all periods when the monitoring system is out of control in your 
semi-annual report.

FR 72812, Nov. 20, 2015]



Sec.  63.7540  How do I demonstrate continuous compliance with the
emission limitations, fuel specifications and work practice standards?

    (a) You must demonstrate continuous compliance with each emission 
limit in Tables 1 and 2 or 11 through 13 to this subpart, the work 
practice standards in Table 3 to this subpart, and the operating limits 
in Table 4 to this subpart that applies to you according to the methods 
specified in Table 8 to this subpart and paragraphs (a)(1) through (19) 
of this section.
    (1) Following the date on which the initial compliance demonstration 
is completed or is required to be completed under Sec. Sec.  63.7 and 
63.7510, whichever date comes first, operation above the established 
maximum or below the established minimum operating limits shall 
constitute a deviation of established operating limits listed in Table 4 
of this subpart except during performance tests conducted to determine 
compliance with the emission limits or to establish new operating 
limits. Operating limits must be confirmed or reestablished during 
performance tests.
    (2) As specified in Sec.  63.7555(d), you must keep records of the 
type and amount of all fuels burned in each boiler or process heater 
during the reporting period to demonstrate that all fuel types and 
mixtures of fuels burned would result in either of the following:
    (i) Equal to or lower emissions of HCl, mercury, and TSM than the 
applicable emission limit for each pollutant, if you demonstrate 
compliance through fuel analysis.
    (ii) Equal to or lower fuel input of chlorine, mercury, and TSM than 
the maximum values calculated during the last performance test, if you 
demonstrate compliance through performance testing.
    (3) If you demonstrate compliance with an applicable HCl emission 
limit through fuel analysis for a solid or liquid fuel and you plan to 
burn a new type of solid or liquid fuel, you must recalculate the HCl 
emission rate using Equation 16 of Sec.  63.7530 according to paragraphs 
(a)(3)(i) through (iii) of this section. You are not required to conduct 
fuel analyses for the fuels described in Sec.  63.7510(a)(2)(i) through 
(iii). You may exclude the fuels described in Sec.  63.7510(a)(2)(i) 
through (iii) when recalculating the HCl emission rate.
    (i) You must determine the chlorine concentration for any new fuel 
type in units of pounds per million Btu, based on supplier data or your 
own fuel analysis, according to the provisions in your site-specific 
fuel analysis plan developed according to Sec.  63.7521(b).
    (ii) You must determine the new mixture of fuels that will have the 
highest content of chlorine.

[[Page 166]]

    (iii) Recalculate the HCl emission rate from your boiler or process 
heater under these new conditions using Equation 16 of Sec.  63.7530. 
The recalculated HCl emission rate must be less than the applicable 
emission limit.
    (4) If you demonstrate compliance with an applicable HCl emission 
limit through performance testing and you plan to burn a new type of 
fuel or a new mixture of fuels, you must recalculate the maximum 
chlorine input using Equation 7 of Sec.  63.7530. If the results of 
recalculating the maximum chlorine input using Equation 7 of Sec.  
63.7530 are greater than the maximum chlorine input level established 
during the previous performance test, then you must conduct a new 
performance test within 60 days of burning the new fuel type or fuel 
mixture according to the procedures in Sec.  63.7520 to demonstrate that 
the HCl emissions do not exceed the emission limit. You must also 
establish new operating limits based on this performance test according 
to the procedures in Sec.  63.7530(b). In recalculating the maximum 
chlorine input and establishing the new operating limits, you are not 
required to conduct fuel analyses for and include the fuels described in 
Sec.  63.7510(a)(2)(i) through (iii).
    (5) If you demonstrate compliance with an applicable mercury 
emission limit through fuel analysis, and you plan to burn a new type of 
fuel, you must recalculate the mercury emission rate using Equation 17 
of Sec.  63.7530 according to the procedures specified in paragraphs 
(a)(5)(i) through (iii) of this section. You are not required to conduct 
fuel analyses for the fuels described in Sec.  63.7510(a)(2)(i) through 
(iii). You may exclude the fuels described in Sec.  63.7510(a)(2)(i) 
through (iii) when recalculating the mercury emission rate.
    (i) You must determine the mercury concentration for any new fuel 
type in units of pounds per million Btu, based on supplier data or your 
own fuel analysis, according to the provisions in your site-specific 
fuel analysis plan developed according to Sec.  63.7521(b).
    (ii) You must determine the new mixture of fuels that will have the 
highest content of mercury.
    (iii) Recalculate the mercury emission rate from your boiler or 
process heater under these new conditions using Equation 17 of Sec.  
63.7530. The recalculated mercury emission rate must be less than the 
applicable emission limit.
    (6) If you demonstrate compliance with an applicable mercury 
emission limit through performance testing, and you plan to burn a new 
type of fuel or a new mixture of fuels, you must recalculate the maximum 
mercury input using Equation 8 of Sec.  63.7530. If the results of 
recalculating the maximum mercury input using Equation 8 of Sec.  
63.7530 are higher than the maximum mercury input level established 
during the previous performance test, then you must conduct a new 
performance test within 60 days of burning the new fuel type or fuel 
mixture according to the procedures in Sec.  63.7520 to demonstrate that 
the mercury emissions do not exceed the emission limit. You must also 
establish new operating limits based on this performance test according 
to the procedures in Sec.  63.7530(b). You are not required to conduct 
fuel analyses for the fuels described in Sec.  63.7510(a)(2)(i) through 
(iii). You may exclude the fuels described in Sec.  63.7510(a)(2)(i) 
through (iii) when recalculating the mercury emission rate.
    (7) If your unit is controlled with a fabric filter, and you 
demonstrate continuous compliance using a bag leak detection system, you 
must initiate corrective action within 1 hour of a bag leak detection 
system alert and complete corrective actions as soon as practical, and 
operate and maintain the fabric filter system such that the periods 
which would cause an alert are no more than 5 percent of the operating 
time during a 6-month period. You must also keep records of the date, 
time, and duration of each alert, the time corrective action was 
initiated and completed, and a brief description of the cause of the 
alert and the corrective action taken. You must also record the percent 
of the operating time during each 6-month period that the conditions 
exist for an alert. In calculating this operating time percentage, if 
inspection of the fabric filter demonstrates that no corrective action 
is required, no alert time is counted. If corrective action is required, 
each alert shall be counted as a minimum of 1 hour. If you take longer 
than 1 hour

[[Page 167]]

to initiate corrective action, the alert time shall be counted as the 
actual amount of time taken to initiate corrective action.
    (8) To demonstrate compliance with the applicable alternative CO 
CEMS emission limit listed in Tables 1, 2, or 11 through 13 to this 
subpart, you must meet the requirements in paragraphs (a)(8)(i) through 
(iv) of this section.
    (i) Continuously monitor CO according to Sec. Sec.  63.7525(a) and 
63.7535.
    (ii) Maintain a CO emission level below or at your applicable 
alternative CO CEMS-based standard in Tables 1 or 2 or 11 through 13 to 
this subpart at all times the affected unit is subject to numeric 
emission limits.
    (iii) Keep records of CO levels according to Sec.  63.7555(b).
    (iv) You must record and make available upon request results of CO 
CEMS performance audits, dates and duration of periods when the CO CEMS 
is out of control to completion of the corrective actions necessary to 
return the CO CEMS to operation consistent with your site-specific 
monitoring plan.
    (9) The owner or operator of a boiler or process heater using a PM 
CPMS or a PM CEMS to meet requirements of this subpart shall install, 
certify, operate, and maintain the PM CPMS or PM CEMS in accordance with 
your site-specific monitoring plan as required in Sec.  63.7505(d).
    (10) If your boiler or process heater has a heat input capacity of 
10 million Btu per hour or greater, you must conduct an annual tune-up 
of the boiler or process heater to demonstrate continuous compliance as 
specified in paragraphs (a)(10)(i) through (vi) of this section. You 
must conduct the tune-up while burning the type of fuel (or fuels in 
case of units that routinely burn a mixture) that provided the majority 
of the heat input to the boiler or process heater over the 12 months 
prior to the tune-up. This frequency does not apply to limited-use 
boilers and process heaters, as defined in Sec.  63.7575, or units with 
continuous oxygen trim systems that maintain an optimum air to fuel 
ratio.
    (i) As applicable, inspect the burner, and clean or replace any 
components of the burner as necessary (you may perform the burner 
inspection any time prior to the tune-up or delay the burner inspection 
until the next scheduled unit shutdown). Units that produce electricity 
for sale may delay the burner inspection until the first outage, not to 
exceed 36 months from the previous inspection. At units where entry into 
a piece of process equipment or into a storage vessel is required to 
complete the tune-up inspections, inspections are required only during 
planned entries into the storage vessel or process equipment;
    (ii) Inspect the flame pattern, as applicable, and adjust the burner 
as necessary to optimize the flame pattern. The adjustment should be 
consistent with the manufacturer's specifications, if available;
    (iii) Inspect the system controlling the air-to-fuel ratio, as 
applicable, and ensure that it is correctly calibrated and functioning 
properly (you may delay the inspection until the next scheduled unit 
shutdown). Units that produce electricity for sale may delay the 
inspection until the first outage, not to exceed 36 months from the 
previous inspection;
    (iv) Optimize total emissions of CO. This optimization should be 
consistent with the manufacturer's specifications, if available, and 
with any NOX requirement to which the unit is subject;
    (v) Measure the concentrations in the effluent stream of CO in parts 
per million, by volume, and oxygen in volume percent, before and after 
the adjustments are made (measurements may be either on a dry or wet 
basis, as long as it is the same basis before and after the adjustments 
are made). Measurements may be taken using a portable CO analyzer; and
    (vi) Maintain on-site and submit, if requested by the Administrator, 
a report containing the information in paragraphs (a)(10)(vi)(A) through 
(C) of this section,
    (A) The concentrations of CO in the effluent stream in parts per 
million by volume, and oxygen in volume percent, measured at high fire 
or typical operating load, before and after the tune-up of the boiler or 
process heater;
    (B) A description of any corrective actions taken as a part of the 
tune-up; and
    (C) The type and amount of fuel used over the 12 months prior to the 
tune-

[[Page 168]]

up, but only if the unit was physically and legally capable of using 
more than one type of fuel during that period. Units sharing a fuel 
meter may estimate the fuel used by each unit.
    (11) If your boiler or process heater has a heat input capacity of 
less than 10 million Btu per hour (except as specified in paragraph 
(a)(12) of this section), you must conduct a biennial tune-up of the 
boiler or process heater as specified in paragraphs (a)(10)(i) through 
(vi) of this section to demonstrate continuous compliance.
    (12) If your boiler or process heater has a continuous oxygen trim 
system that maintains an optimum air to fuel ratio, or a heat input 
capacity of less than or equal to 5 million Btu per hour and the unit is 
in the units designed to burn gas 1; units designed to burn gas 2 
(other); or units designed to burn light liquid subcategories, or meets 
the definition of limited-use boiler or process heater in Sec.  63.7575, 
you must conduct a tune-up of the boiler or process heater every 5 years 
as specified in paragraphs (a)(10)(i) through (vi) of this section to 
demonstrate continuous compliance. You may delay the burner inspection 
specified in paragraph (a)(10)(i) of this section until the next 
scheduled or unscheduled unit shutdown, but you must inspect each burner 
at least once every 72 months. If an oxygen trim system is utilized on a 
unit without emission standards to reduce the tune-up frequency to once 
every 5 years, set the oxygen level no lower than the oxygen 
concentration measured during the most recent tune-up.
    (13) If the unit is not operating on the required date for a tune-
up, the tune-up must be conducted within 30 calendar days of startup.
    (14) If you are using a CEMS measuring mercury emissions to meet 
requirements of this subpart you must install, certify, operate, and 
maintain the mercury CEMS as specified in paragraphs (a)(14)(i) and (ii) 
of this section.
    (i) Operate the mercury CEMS in accordance with performance 
specification 12A of 40 CFR part 60, appendix B or operate a sorbent 
trap based integrated monitor in accordance with performance 
specification 12B of 40 CFR part 60, appendix B. The duration of the 
performance test must be 30 operating days if you specified a 30 
operating day basis in Sec.  63.7545(e)(2)(iii) for mercury CEMS or it 
must be 720 hours if you specified a 720 hour basis in Sec.  
63.7545(e)(2)(iii) for mercury CEMS. For each day in which the unit 
operates, you must obtain hourly mercury concentration data, and stack 
gas volumetric flow rate data.
    (ii) If you are using a mercury CEMS, you must install, operate, 
calibrate, and maintain an instrument for continuously measuring and 
recording the mercury mass emissions rate to the atmosphere according to 
the requirements of performance specifications 6 and 12A of 40 CFR part 
60, appendix B, and quality assurance procedure 6 of 40 CFR part 60, 
appendix F.
    (15) If you are using a CEMS to measure HCl emissions to meet 
requirements of this subpart, you must install, certify, operate, and 
maintain the HCl CEMS as specified in paragraphs (a)(15)(i) and (ii) of 
this section. This option for an affected unit takes effect on the date 
a final performance specification for an HCl CEMS is published in the 
Federal Register or the date of approval of a site-specific monitoring 
plan.
    (i) Operate the continuous emissions monitoring system in accordance 
with the applicable performance specification in 40 CFR part 60, 
appendix B. The duration of the performance test must be 30 operating 
days if you specified a 30 operating day basis in Sec.  
63.7545(e)(2)(iii) for HCl CEMS or it must be 720 hours if you specified 
a 720 hour basis in Sec.  63.7545(e)(2)(iii) for HCl CEMS. For each day 
in which the unit operates, you must obtain hourly HCl concentration 
data, and stack gas volumetric flow rate data.
    (ii) If you are using a HCl CEMS, you must install, operate, 
calibrate, and maintain an instrument for continuously measuring and 
recording the HCl mass emissions rate to the atmosphere according to the 
requirements of the applicable performance specification of 40 CFR part 
60, appendix B, and the quality assurance procedures of 40 CFR part 60, 
appendix F.
    (16) If you demonstrate compliance with an applicable TSM emission 
limit through performance testing, and you

[[Page 169]]

plan to burn a new type of fuel or a new mixture of fuels, you must 
recalculate the maximum TSM input using Equation 9 of Sec.  63.7530. If 
the results of recalculating the maximum TSM input using Equation 9 of 
Sec.  63.7530 are higher than the maximum total selected input level 
established during the previous performance test, then you must conduct 
a new performance test within 60 days of burning the new fuel type or 
fuel mixture according to the procedures in Sec.  63.7520 to demonstrate 
that the TSM emissions do not exceed the emission limit. You must also 
establish new operating limits based on this performance test according 
to the procedures in Sec.  63.7530(b). You are not required to conduct 
fuel analyses for the fuels described in Sec.  63.7510(a)(2)(i) through 
(iii). You may exclude the fuels described in Sec.  63.7510(a)(2)(i) 
through (iii) when recalculating the TSM emission rate.
    (17) If you demonstrate compliance with an applicable TSM emission 
limit through fuel analysis for solid or liquid fuels, and you plan to 
burn a new type of fuel, you must recalculate the TSM emission rate 
using Equation 18 of Sec.  63.7530 according to the procedures specified 
in paragraphs (a)(5)(i) through (iii) of this section. You are not 
required to conduct fuel analyses for the fuels described in Sec.  
63.7510(a)(2)(i) through (iii). You may exclude the fuels described in 
Sec.  63.7510(a)(2)(i) through (iii) when recalculating the TSM emission 
rate.
    (i) You must determine the TSM concentration for any new fuel type 
in units of pounds per million Btu, based on supplier data or your own 
fuel analysis, according to the provisions in your site-specific fuel 
analysis plan developed according to Sec.  63.7521(b).
    (ii) You must determine the new mixture of fuels that will have the 
highest content of TSM.
    (iii) Recalculate the TSM emission rate from your boiler or process 
heater under these new conditions using Equation 18 of Sec.  63.7530. 
The recalculated TSM emission rate must be less than the applicable 
emission limit.
    (18) If you demonstrate continuous PM emissions compliance with a PM 
CPMS you will use a PM CPMS to establish a site-specific operating limit 
corresponding to the results of the performance test demonstrating 
compliance with the PM limit. You will conduct your performance test 
using the test method criteria in Table 5 of this subpart. You will use 
the PM CPMS to demonstrate continuous compliance with this operating 
limit. You must repeat the performance test annually and reassess and 
adjust the site-specific operating limit in accordance with the results 
of the performance test.
    (i) To determine continuous compliance, you must record the PM CPMS 
output data for all periods when the process is operating and the PM 
CPMS is not out-of-control. You must demonstrate continuous compliance 
by using all quality-assured hourly average data collected by the PM 
CPMS for all operating hours to calculate the arithmetic average 
operating parameter in units of the operating limit (milliamps) on a 30-
day rolling average basis.
    (ii) For any deviation of the 30-day rolling PM CPMS average value 
from the established operating parameter limit, you must:
    (A) Within 48 hours of the deviation, visually inspect the air 
pollution control device (APCD);
    (B) If inspection of the APCD identifies the cause of the deviation, 
take corrective action as soon as possible and return the PM CPMS 
measurement to within the established value; and
    (C) Within 30 days of the deviation or at the time of the annual 
compliance test, whichever comes first, conduct a PM emissions 
compliance test to determine compliance with the PM emissions limit and 
to verify or re-establish the CPMS operating limit. You are not required 
to conduct additional testing for any deviations that occur between the 
time of the original deviation and the PM emissions compliance test 
required under this paragraph.
    (iii) PM CPMS deviations from the operating limit leading to more 
than four required performance tests in a 12-month operating period 
constitute a separate violation of this subpart.
    (19) If you choose to comply with the PM filterable emissions limit 
by using PM CEMS you must install, certify, operate, and maintain a PM 
CEMS and record the output of the PM CEMS as

[[Page 170]]

specified in paragraphs (a)(19)(i) through (vii) of this section. The 
compliance limit will be expressed as a 30-day rolling average of the 
numerical emissions limit value applicable for your unit in Tables 1 or 
2 or 11 through 13 of this subpart.
    (i) Install and certify your PM CEMS according to the procedures and 
requirements in Performance Specification 11--Specifications and Test 
Procedures for Particulate Matter Continuous Emission Monitoring Systems 
at Stationary Sources in Appendix B to part 60 of this chapter, using 
test criteria outlined in Table V of this rule. The reportable 
measurement output from the PM CEMS must be expressed in units of the 
applicable emissions limit (e.g., lb/MMBtu, lb/MWh).
    (ii) Operate and maintain your PM CEMS according to the procedures 
and requirements in Procedure 2-- Quality Assurance Requirements for 
Particulate Matter Continuous Emission Monitoring Systems at Stationary 
Sources in Appendix F to part 60 of this chapter.

CEMS at least once annually.
    (B) You must conduct the relative correlation audit (RCA) for your 
PM CEMS at least once every 3 years.
    (iii) Collect PM CEMS hourly average output data for all boiler 
operating hours except as indicated in paragraph (v) of this section.
    (iv) Calculate the arithmetic 30-day rolling average of all of the 
hourly average PM CEMS output data collected during all nonexempt boiler 
or process heater operating hours.
    (v) You must collect data using the PM CEMS at all times the unit is 
operating and at the intervals specified this paragraph (a), except for 
periods of monitoring system malfunctions, repairs associated with 
monitoring system malfunctions, and required monitoring system quality 
assurance or quality control activities.
    (vi) You must use all the data collected during all boiler or 
process heater operating hours in assessing the compliance with your 
operating limit except:
    (A) Any data collected during monitoring system malfunctions, 
repairs associated with monitoring system malfunctions, or required 
monitoring system quality assurance or control activities conducted 
during monitoring system malfunctions in calculations and report any 
such periods in your annual deviation report;
    (B) Any data collected during periods when the monitoring system is 
out of control as specified in your site-specific monitoring plan, 
repairs associated with periods when the monitoring system is out of 
control, or required monitoring system quality assurance or control 
activities conducted during out of control periods in calculations used 
to report emissions or operating levels and report any such periods in 
your annual deviation report;
    (C) Any data recorded during periods of startup or shutdown.
    (vii) You must record and make available upon request results of PM 
CEMS system performance audits, dates and duration of periods when the 
PM CEMS is out of control to completion of the corrective actions 
necessary to return the PM CEMS to operation consistent with your site-
specific monitoring plan.
    (b) You must report each instance in which you did not meet each 
emission limit and operating limit in Tables 1 through 4 or 11 through 
13 to this subpart that apply to you. These instances are deviations 
from the emission limits or operating limits, respectively, in this 
subpart. These deviations must be reported according to the requirements 
in Sec.  63.7550.
    (c) If you elected to demonstrate that the unit meets the 
specification for mercury for the unit designed to burn gas 1 
subcategory, you must follow the sampling frequency specified in 
paragraphs (c)(1) through (4) of this section and conduct this sampling 
according to the procedures in Sec.  63.7521(f) through (i).
    (1) If the initial mercury constituents in the gaseous fuels are 
measured to be equal to or less than half of the mercury specification 
as defined in Sec.  63.7575, you do not need to conduct further 
sampling.
    (2) If the initial mercury constituents are greater than half but 
equal to or less than 75 percent of the mercury specification as defined 
in Sec.  63.7575, you

[[Page 171]]

will conduct semi-annual sampling. If 6 consecutive semi-annual fuel 
analyses demonstrate 50 percent or less of the mercury specification, 
you do not need to conduct further sampling. If any semi-annual sample 
exceeds 75 percent of the mercury specification, you must return to 
monthly sampling for that fuel, until 12 months of fuel analyses again 
are less than 75 percent of the compliance level.
    (3) If the initial mercury constituents are greater than 75 percent 
of the mercury specification as defined in Sec.  63.7575, you will 
conduct monthly sampling. If 12 consecutive monthly fuel analyses 
demonstrate 75 percent or less of the mercury specification, you may 
decrease the fuel analysis frequency to semi-annual for that fuel.
    (4) If the initial sample exceeds the mercury specification as 
defined in Sec.  63.7575, each affected boiler or process heater 
combusting this fuel is not part of the unit designed to burn gas 1 
subcategory and must be in compliance with the emission and operating 
limits for the appropriate subcategory. You may elect to conduct 
additional monthly sampling while complying with these emissions and 
operating limits to demonstrate that the fuel qualifies as another gas 1 
fuel. If 12 consecutive monthly fuel analyses samples are at or below 
the mercury specification as defined in Sec.  63.7575, each affected 
boiler or process heater combusting the fuel can elect to switch back 
into the unit designed to burn gas 1 subcategory until the mercury 
specification is exceeded.
    (d) For startup and shutdown, you must meet the work practice 
standards according to items 5 and 6 of Table 3 of this subpart.

is out of control as specified in your site-specific monitoring plan, 
while conducting repairs associated with periods when the monitoring 
system is out of control, or while conducting required monitoring system 
quality assurance or quality control activities, and periods when this 
unit is not operating. The 240 hours should be consecutive, but not 
necessarily continuous if operations were intermittent.
    30-day rolling average means the arithmetic mean of the previous 720

    Dutch oven means a unit having a refractory-walled cell connected to 
a conventional boiler setting. Fuel materials are introduced through an 
opening in the roof of the dutch oven and burn in a pile on its floor. 
Fluidized bed boilers are not part of the dutch oven design category.
    Efficiency credit means emission reductions above those required by 
this subpart. Efficiency credits generated may be used to comply with 
the emissions limits. Credits may come from pollution prevention 
projects that result in reduced fuel use by affected units. Boilers that

one-third of its potential

[[Page 184]]

electric output capacity and more than 25 MWe output to any utility 
power distribution system for sale is considered an electric utility 
steam generating unit. To be ``capable of combusting'' fossil fuels, an 
EGU would need to have these fuels allowed in their operating permits 
and have the appropriate fuel handling facilities on-site or otherwise 
available (e.g., coal handling equipment, including coal storage area, 
belts and conveyers, pulverizers, etc.; oil storage facilities). In 
addition, fossil fuel-fired EGU means any EGU that fired fossil fuel for

evaluated to identify energy savings opportunities, within the limit of 
performing an 8-hour on-site energy assessment.
    (2) The energy assessment for facilities with affected boilers and 
process heaters with a combined heat input capacity of 0.3 to 1.0 TBtu/

additional 1.0 TBtu/yr not to exceed 160 on-site technical hours, but 
may be longer at the discretion of the owner or operator of the affected 
source. The boiler system(s), process heater(s), and any on-site energy 
use system(s) accounting for at least 20 percent of the energy (e.g.,

mercury, selenium, or arsenic) using an aliquot of the dried sample, 
then the drying temperature must be modified to prevent vaporizing these 
metals. On the other hand, if metals analysis is done on an ``as 
received'' basis, a separate aliquot can be dried to determine moisture 
content and the metals concentration mathematically adjusted to a dry 
basis.
    (6) An equivalent pollutant (mercury, HCl) determinative or 
analytical procedure means a published VCS or EPA method that clearly 
states that the standard, practice, or method is appropriate for the

capture particulate matter by filtering gas streams through filter 
media, also known as a baghouse. A fabric filter is a dry control 
system.

enforceable by the EPA Administrator, including, but not limited to, the 
requirements of 40 CFR parts 60, 61, 63, and 65, requirements within any 
applicable state implementation plan, and any permit requirements 
established under 40 CFR 52.21 or under 40 CFR 51.18 and 40 CFR 51.24.
    Fluidized bed boiler means a boiler utilizing a fluidized bed 
combustion process that is not a pulverized coal boiler.
    Fluidized bed boiler with an integrated fluidized bed heat exchanger 
means a boiler utilizing a fluidized bed combustion where the entire 
tube surface area is located outside of the furnace section at the exit 
of the cyclone section and exposed to the flue gas stream for conductive 
heat transfer. This design applies only to boilers in the unit designed 
to burn coal/solid fossil fuel subcategory that fire coal refuse.
    Fluidized bed combustion means a process where a fuel is burned in a 
bed

[[Page 186]]

of granulated particles, which are maintained in a mobile suspension by 
the forward flow of air and combustion products.
    Fossil fuel means natural gas, oil, coal, and any form of solid, 
liquid, or gaseous fuel derived from such material.
    Fuel cell means a boiler type in which the fuel is dropped onto 
suspended fixed grates and is fired in a pile. The refractory-lined fuel 
cell uses combustion air preheating and positioning of secondary and 
tertiary air injection ports to improve boiler efficiency. Fluidized 
bed, dutch oven, pile burner, hybrid suspension grate, and suspension

furnace gas and process gases that are regulated under another subpart 
of this part, or part 60, part 61, or part 65 of this chapter, are 
exempted from this definition.
    Heat input means heat derived from combustion of fuel in a boiler or 
process heater and does not include the heat input from preheated 
combustion air, recirculated flue gases, returned condensate, or exhaust 
gases from other sources such as gas turbines, internal combustion 
engines, kilns, etc.
    Heavy liquid includes residual oil and any other liquid fuel not 
classified as a light liquid.
    Hourly average means the arithmetic average of at least four CMS 
data values representing the four 15-minute periods in an hour, or at 
least two 15-minute data values during an hour when CMS calibration, 
quality assurance, or maintenance activities are being performed.

external to the vessel. Hot water boilers (i.e., not generating steam) 
combusting gaseous, liquid, or biomass fuel with a heat input capacity 
of less than 1.6 million Btu per hour are included in this definition. 
The 120 U.S. gallon capacity threshold to be considered a hot water 
heater is independent of the 1.6 MMBtu/hr heat input capacity threshold 
for hot water boilers. Hot water heater also means a tankless unit that 
provides on demand hot water.
    Hybrid suspension grate boiler means a boiler designed with air 
distributors to spread the fuel material over the entire width and depth 
of the boiler combustion zone. The biomass fuel combusted in these units 
exceeds a moisture content of 40 percent on an as-fired annual heat 
input basis as demonstrated by monthly fuel analysis. The drying and 
much of the combustion of the fuel takes place in suspension, and the 
combustion is completed on the grate or floor of the boiler. Fluidized 
bed, dutch oven, and pile burner designs are not part of the hybrid 
suspension grate boiler design category.
    Industrial boiler means a boiler used in manufacturing, processing, 
mining, and refining or any other industry to provide steam, hot water, 
and/or electricity.
    Light liquid includes distillate oil, biodiesel, or vegetable oil.

heater divided by heat input during the performance test that 
established the minimum sorbent injection rate or minimum activated 
carbon injection rate, expressed as a fraction (e.g., for 50 percent 
load the load fraction is 0.5). For boilers and process heaters that co-
fire natural gas or refinery gas with a solid or liquid fuel, the load 
fraction is

[[Page 187]]

determined by the actual heat input of the solid or liquid fuel divided 
by heat input of the solid or liquid fuel fired during the performance 
test (e.g., if the performance test was conducted at 100 percent solid 
fuel firing, for 100 percent load firing 50 percent solid fuel and 50 
percent natural gas the load fraction is 0.5).

or dry sorbent injection control technology to comply with the HCl 
emission limit, the lowest average ratio of sorbent to sulfur measured 
during the most recent performance test.
    Minimum total secondary electric power means the lowest hourly 
average total secondary electric power determined from the values of 
secondary voltage and secondary current to the electrostatic 
precipitator measured according to Table 7 to this subpart during the 
most recent performance test demonstrating compliance with the 
applicable emission limits.
    Natural gas means:
    (1) A naturally occurring mixture of hydrocarbon and nonhydrocarbon 
gases

[[Page 188]]

found in geologic formations beneath the earth's surface, of which the 
principal constituent is methane; or
    (2) Liquefied petroleum gas, as defined in ASTM D1835 (incorporated 
by reference, see Sec.  63.14); or
    (3) A mixture of hydrocarbons that maintains a gaseous state at ISO

of light and obscure the view of an object in the background.
    Operating day means a 24-hour period between 12 midnight and the 
following midnight during which any fuel is combusted at any time in the 
boiler or process heater unit. It is not necessary for fuel to be 
combusted for the entire 24-hour period. For calculating rolling average 
emissions, an operating day does not include the hours of operation 
during startup or shutdown.
    Other combustor means a unit designed to burn solid fuel that is not 
classified as a dutch oven, fluidized bed, fuel cell, hybrid suspension 
grate boiler, pulverized coal boiler, stoker, sloped grate, or 
suspension boiler as defined in this subpart.
    Other gas 1 fuel means a gaseous fuel that is not natural gas or 
refinery gas and does not exceed a maximum concentration of 40 
micrograms/cubic meters of mercury.
    Oxygen analyzer system means all equipment required to determine the 
oxygen content of a gas stream and used to monitor oxygen in the boiler 
or process heater flue gas, boiler or process heater, firebox, or other 
appropriate location. This definition includes oxygen trim systems. The 
source owner or operator must install, calibrate, maintain, and operate 
the oxygen analyzer system in accordance with the manufacturer's 
recommendations.
    Oxygen trim system means a system of monitors that is used to 
maintain excess air at the desired level in a combustion device over its 
operating load range. A typical system consists of a flue gas oxygen 
and/or CO monitor that automatically provides a feedback signal to the 
combustion air controller or draft controller.
    Particulate matter (PM) means any finely divided solid or liquid 
material, other than uncombined water, as measured by the test methods 
specified under this subpart, or an approved alternative method.
    Period of gas curtailment or supply interruption means a period of 
time during which the supply of gaseous fuel to an affected boiler or 
process heater is restricted or halted for reasons beyond the control of 
the facility. The act of entering into a contractual agreement with a 
supplier of natural gas established for curtailment purposes does not 
constitute a reason that is under the control of a facility for the 
purposes of this definition. An increase in the cost or unit price of 
natural gas due to normal market fluctuations not during periods of 
supplier delivery restriction does not constitute a period of natural 
gas curtailment or supply interruption. On-site gaseous fuel system 
emergencies or equipment failures qualify as periods of supply 
interruption when the emergency or failure is beyond the control of the 
facility.
    Pile burner means a boiler design incorporating a design where the 
anticipated biomass fuel has a high relative moisture content. Grates 
serve to support the fuel, and underfire air flowing up through the 
grates provides oxygen for combustion, cools the grates, promotes 
turbulence in the fuel bed, and fires the fuel. The most common form of 
pile burning is the dutch oven.
    Process heater means an enclosed device using controlled flame, and 
the unit's primary purpose is to transfer heat indirectly to a process 
material (liquid, gas, or solid) or to a heat transfer material (e.g., 
glycol or a mixture of glycol and water) for use in a process unit, 
instead of generating steam. Process heaters are devices in which the 
combustion gases do not come into direct contact with process materials.

[[Page 189]]

A device combusting solid waste, as defined in Sec.  241.3 of this 
chapter, is not a process heater unless the device is exempt from the 
definition of a solid waste incineration unit as provided in section 
129(g)(1) of the Clean Air Act. Process heaters do not include units 
used for comfort heat or space heat, food preparation for on-site 
consumption, or autoclaves. Waste heat process heaters are excluded from 
this definition.
    Pulverized coal boiler means a boiler in which pulverized coal or 
other solid fossil fuel is introduced into an air stream that carries 
the coal to the combustion chamber of the boiler where it is fired in 
suspension.

is supplied for heating, and/or producing electricity, or for any other 
purpose, or
    (2) The period in which operation of a boiler or process heater is 
initiated for any purpose. Startup begins with either the first-ever 
firing of fuel in a boiler or process heater for the purpose of

steam output,
    (2) For a boiler that cogenerates process steam and electricity 
(also known as combined heat and power), the total energy output, which 
is the sum of the energy content of the steam exiting the turbine and 
sent to process in MMBtu and the energy of the electricity generated 
converted to MMBtu at a rate of 10,000 Btu per kilowatt-hour generated 
(10 MMBtu per megawatt-hour), and
    (3) For a boiler that generates only electricity, the alternate 
output-based emission limits would be the appropriate emission limit 
from Table 1 or 2 of this subpart in units of pounds per million Btu 
heat input (lb per MWh).
    (4) For a boiler that performs multiple functions and produces steam 
to be used for any combination of paragraphs (1), (2), and (3) of this 
definition that includes electricity generation of paragraph (3) of this 
definition, the total energy output, in terms of MMBtu of steam output, 
is the sum of the energy content of steam sent directly to the process 
and/or used for heating (S1), the energy content of turbine 
steam sent to process plus energy in electricity according to paragraph

[[Page 191]]

(2) of this definition (S2), and the energy content of 
electricity generated by a electricity only turbine as paragraph (3) of 
this definition (MW(3)) and would be calculated using 
Equation 21 of this section. In the case of boilers supplying steam to 
one or more common heaters, S1, S2, and 
MW(3) for each boiler would be calculated based on the its 
(steam energy) contribution (fraction of total steam energy) to the 
common heater.

\a\ If you are conducting stack tests to demonstrate compliance and your performance tests for this pollutant
  for at least 2 consecutive years show that your emissions are at or below this limit, you can skip testing
  according to Sec.   63.7515 if all of the other provisions of Sec.   63.7515 are met. For all other pollutants
  that do not contain a footnote ``a'', your performance tests for this pollutant for at least 2 consecutive
  years must show that your emissions are at or below 75 percent of this limit in order to qualify for skip
  testing.
\b\ Incorporated by reference, see Sec.   63.14.
\c\ If your affected source is a new or reconstructed affected source that commenced construction or
  reconstruction after June 4, 2010, and before April 1, 2013, you may comply with the emission limits in Tables
  11, 12 or 13 to this subpart until January 31, 2016. On and after January 31, 2016, you must comply with the
  emission limits in Table 1 to this subpart.
\d\ An owner or operator may request an alternative test method under Sec.   63.7 of this chapter, in order that
  compliance with the carbon monoxide emissions limit be determined using carbon dioxide as a diluent correction
  in place of oxygen at 3%. EPA Method 19 F-factors and EPA Method 19 equations must be used to generate the
  appropriate CO2 correction percentage for the fuel type burned in the unit, and must also take into account
  that the 3% oxygen correction is to be done on a dry basis. The alternative test method request must account
  for any CO2 being added to, or removed from, the emissions gas stream as a result of limestone injection,
  scrubber media, etc.

\a\ If you are conducting stack tests to demonstrate compliance and your performance tests for this pollutant
  for at least 2 consecutive years show that your emissions are at or below this limit, you can skip testing
  according to Sec.   63.7515 if all of the other provisions of Sec.   63.7515 are met. For all other pollutants
  that do not contain a footnote a, your performance tests for this pollutant for at least 2 consecutive years
  must show that your emissions are at or below 75 percent of this limit in order to qualify for skip testing.
\b\ Incorporated by reference, see Sec.   63.14.
\c\ An owner or operator may request an alternative test method under Sec.   63.7 of this chapter, in order that
  compliance with the carbon monoxide emissions limit be determined using carbon dioxide as a diluent correction
  in place of oxygen at 3%. EPA Method 19 F-factors and EPA Method 19 equations must be used to generate the
  appropriate CO2 correction percentage for the fuel type burned in the unit, and must also take into account
  that the 3% oxygen correction is to be done on a dry basis. The alternative test method request must account
  for any CO2 being added to, or removed from, the emissions gas stream as a result of limestone injection,
  scrubber media, etc.
