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, 1997), 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.
OBSOLETE PROVISIONS
Provisions that become obsolete before the revision date stated on
the cover of each volume are not carried. Code users may find the text
of provisions in effect on a given date in the past by using the
appropriate numerical list of sections affected. For the period before
January 1, 1986, consult either the List of CFR Sections Affected, 1949-
1963, 1964-1972, or 1973-1985, published in seven separate volumes. For
the period beginning January 1, 1986, a ``List of CFR Sections
Affected'' is published at the end of each CFR volume.
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.
Properly approved incorporations by reference in this volume are
listed in the Finding Aids at the end of this volume.
What if the material incorporated by reference cannot be found? If
you have any problem locating or obtaining a copy of material listed in
the Finding Aids of this volume 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, Washington DC
20408, or call (202) 523-4534.
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 Statutory
Authorities and Agency Rules (Table I), and Acts Requiring Publication
in the Federal Register (Table II). A list of CFR titles, chapters, and
parts and an alphabetical list of agencies publishing in the CFR are
also included in this volume.
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.
[[Page vii]]
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.

General Provisions
Sec. 425.01 Applicability.
This part applies to any leather tanning and finishing facility
which discharges or may discharge process wastewater pollutants to the
waters of the United States, or which introduces or may introduce
process wastewater pollutants into a publicly owned treatment works.
Sec. 425.02 General definitions.
In addition to the definitions set forth in 40 CFR part 401, the
following definitions apply to this part:
(a) ``Sulfide'' shall mean total sulfide as measured by the
potassium ferricyanide titration method described in Appendix A or the
modified Monier-Williams method described in Appendix B.
(b) ``Hide'' means any animal pelt or skin as received by a tannery
as raw material to be processed.
(c) ``Retan-wet finish'' means the final processing steps performed
on a tanned hide including, but not limited to, the following wet
processes: retan, bleach, color, and fatliquor.
(d) ``Hair pulp'' means the removal of hair by chemical dissolution.
(e) ``Hair save'' means the physical or mechanical removal of hair
which has not been chemically dissolved, and either selling the hair as
a by-product or disposing of it as a solid waste.
(f) ``Chrome tan'' means the process of converting hide into leather
using a form of chromium.
(g) ``Vegetable tan'' means the process of converting hides into
leather using chemicals either derived from vegetable matter or
synthesized to produce effects similar to those chemicals.
(h) ``Raw material'' means the hides received by the tannery except
for facilities covered by subpart D and subpart I where ``raw material''
means the hide or split in the condition in which it is first placed
into a wet process.
(i) ``Monthly average'' means the arithmetic average of eight (8)
individual data points from effluent sampling and analysis during any
calendar month.
(j) ``Interference'' means the discharge of sulfides in quantities
which can result in human health hazards and/or risks to human life, and

[47 FR 52870, Nov. 23, 1982, as amended at 53 FR 9181, Mar. 21, 1988]
Sec. 425.03 Sulfide analytical methods and applicability.
(a) The potassium ferricyanide titration method described in
appendix A to part 425 shall be used whenever practicable for the
determination of sulfide in wastewaters discharged by plants operating
in all subcategories except the hair save or pulp, non-chrome tan,
retan-wet finish subcategory (subpart C, see Sec. 425.30). In all other
cases, the modified Monier-Williams method as described in appendix B to
part 425 shall be used as an alternative to the potassium ferricyanide
titration method for the determination of sulfide in wastewaters
discharged by plants operating in all subcategories except subpart C.
(b) The modified Monier-Williams method as described in appendix B
to part 425 shall be used for the determination of sulfide in
wastewaters discharged by plants operating in the hair save or pulp,
non-chrome tan, retan-wet finish subcategory (subpart C, see
Sec. 425.30).
[53 FR 9181, Mar. 21, 1988]
Sec. 425.04 Applicability of sulfide pretreatment standards.
(a) A POTW receiving wastewater from a facility subject to this part
may require more stringent pretreatment
[[Page 8]]
standards for sulfide than those established by this part without EPA
approval.
(b) The pretreatment standards for sulfide established by this part
will not apply if the POTW receiving wastewater from a facility subject
to this part certifies in writing with explanation of relevant factors
considered, in accordance with the provisions of paragraph (c) of this
section, that the discharge of sulfide from the facility does not
interfere with the operation of the POTW. In making this determination,
the POTW shall consider all relevant factors including but not limited
to the following:
(1) The presence and characteristics, of other industrial
wastewaters which can increase or decrease sulfide concentrations, pH,
or both.
(2) The characteristics of the sewer/interceptor collection system
which either minimize or enhance opportunities for release of hydrogen
sulfide gas.
(3) The characteristics of the receiving POTWs headworks,
preliminary and primary treatment systems, and sludge holding and
dewatering facilities which either minimize or enhance opportunities for
release of hydrogen sulfide gas.
(4) The occurrence of any prior sulfide related interference as
defined in Sec. 425.02(j).
(c)(1) On October 13, 1983, a POTW which intends to certify that the
sulfide pretreatment standard should not apply must publish, in a local
newspaper with the largest circulation, a notice that presents the
findings supporting this determination consistent with paragraph (a) of
this section. Allowance for public hearing of these findings also must
be provided. The POTW shall identify all existing facilities to which
the sulfide pretreatment standard otherwise established by this part
would not apply.
(2) On January 11, 1984, a POTW which intends to certify that the
sulfide pretreatment standard should not apply must file a written
certification with the Regional Water Management Division Director,
Environmental Protection Agency, in the appropriate Regional Office.
This certification shall include the findings supporting this
determination and the results of public comments, and public hearing(s)
if held.
(3) On February 10, 1984, EPA shall acknowledge to the POTW receipt
of any certification submitted under paragraphs (c) (1) and (2) of this
section, and shall indicate to the POTW the adequacy of the submission
based upon a review of the factors set forth in paragraph (b) of this
section.
(4) Within 30 days of the date of receipt of adequate submissions
under paragraphs (c) (1), (2), and (3) of this section, EPA shall
publish a notice in the Federal Register identifying those facilities to
which the sulfide pretreatment standards of this part shall not apply.
(5) A POTW may certify that the sulfide pretreatment standards of
this part should not apply to a new source planning to discharge into
the POTW. This certification must be submitted prior to the commencement
of discharge, and must conform at a minimum with criteria in paragraph
(b) of this section and the general procedures and intervals of time
contained in paragraphs (c) (1), (2), (3), and (4) of this section.
(d)(1) If, after EPA and the POTW have determined in accordance with
this section that the sulfide pretreatment standards of this part are
not applicable to specified facilities, a POTW then determines that
there have been changed circumstances (including but not limited to
changes in the factors specified in paragraph (b) of this section) which
justify application of the sulfide pretreatment standards, the POTW
shall revoke the certification submitted under paragraph (c) of this
section. The POTW and EPA shall then adhere to the general procedures
and time intervals contained in paragraph (c) of this section in order
to determine whether the sulfide pretreatment standards contained in
this part are applicable.
(2) If pursuant to paragraph (d)(1) of this section, the sulfide
pretreatment standards of this part are applicable to a specified
facility, the indirect discharger shall comply with the sulfide
pretreatment standards no later than 18 months from the date of
publication of the Federal Register notice identifying the facility.
[[Page 9]]
(e) At any time after October 13, 1983, if a POTW determines that
there have been changed circumstances (including but not limited to
changes in the factors specified in paragraph (b) of this section), it
may initiate proceedings contained in paragraph (c) of this section to
determine that the sulfide pretreatment standards of this part shall not
be applicable. The POTW and EPA shall follow the procedures and time
intervals contained in paragraph (c) of this section to make this
determination. A final determination that the sulfide pretreatment
standards are not applicable must be made prior to the discharge of
sulfide not in accordance with the standards set forth in this part.
(The information collection and reporting requirements contained in
paragraphs (b) and (c) were approved by the Office of Management and
Budget under control number 2040-0032)

Appendix A to Part 425--Potassium Ferricyanide Titration Method
Source
The potassium ferricyanide titration method is based on method SLM
4/2 described in ``Official Method of Analysis,'' Society of Leather
Trades' Chemists, Fourth Revised Edition, Redbourn, Herts., England,
1965.
Outline of Method
The buffered sulfide solution is titrated with standard potassium
ferricyanide solution in the presence of a ferrous dimethylglyoxime
ammonia complex. The sulfide is oxidized to sulfur. Sulfite interferes
and must be precipitated with barium chloride. Thiosulfate is not
titrated under the conditions of the determination (Charlot, ``Ann.
chim, anal,'', 1945, 27, 153; Booth; ``J. Soc. Leather Trades'
Chemists,'' 1956, 40, 238).
Apparatus
Burrette, 10 ml.
[[Page 20]]
Reagents
1. Preparation of 0.02N potassium ferricyanide; Weigh to the nearest
tenth of a gram 6.6 g. of analytical reagent grade potassium
ferricyanide and dissolve in 1 liter distilled water. Store in an amber
bottle in the dark. Prepare fresh each week.
2. Standardization of ferricyanide solution: Transfer 50 ml. of
solution to a 250 ml. Erlenmeyer flask. Add several crystals of
potassium iodide (about 1 g.), mix gently to dissolve, add 1 ml. of 6N
hydrochloric acid, stopper the flask, and swirl gently. Let stand for
two minutes, add 10 ml. of a 30 percent zinc sulfate solution, and
titrate the mixture containing the gelatinous precipitate with
standardized sodium thiosulfate or phenylarsine oxide titrant in the
range of 0.025-0.050N Add 1 ml. of starch indicator solution after the
color has faded to a pale yellow, and continue the titration to the
disappearance of the blue color. Calculate the normality of the
ferricyanide solution using the equation:
(ml of thiosulfate added) (normality of thiosulfate)
Normality of Potassium Ferricyanide = ------------------------------------------------------------------------
[K3Fe(CN)6] Ml of K3Fe(CN)6
3. Preparation of 6M ammonium chloride buffer, pH 9.3: Dissolve 200
g. ammonium chloride in approximately 500 ml. distilled water, add 200
ml. 14M reagent grade ammonium hydroxide and make up to 1 liter with
distilled water. The buffer should be prepared in a hood. Store in a
tightly stoppered container.
4. Preparation of 0.05M barium chloride solution: Dissolve 12-13 g.
barium chloride dihydrate in 1 liter of distilled water.
5. Preparation of ferrous dimethylglyoxime indicator solution: Mix
10 ml. 0.6 percent ferrous sulfate, 50 ml. 1 percent dimethylglyoxime in
ethanol, and 0.5 ml. concentrated sulfuric acid.
6. Preparation of stock sulfide standard, 1000 ppm: Dissolve 2.4 g.
reagent grade sodium sulfide in 1 liter of distilled water. Store in a
tightly stoppered container. Diluted working standards must be prepared
fresh daily and their concentrations determined by EPA test procedure
376.1 (see 40 CFR 136.3, Table IB, parameter 66 (49 FR 43234, October
26, 1984, with correction notice at 50 FR 690, January 4, 1985))
immediately prior to use.
7. Preparation of 10N NaOH: Dissolve 400 g. of analytical reagent
grade NaOH in 1 liter distilled water.
Sample Preservation and Storage
Samples are to be field filtered (gravity or pressure) with coarse
filter paper (Whatman 4 or equivalent) immediately after collection.
Filtered samples must be preserved by adjustment to pH> 12 with 10N
NaOH. Sample containers must be covered tightly and stored at 4 deg.C
until analysis. Samples must be analyzed within 48 hours of collection.
If these procedures cannot be achieved, it is the laboratory's
responsibility to institute quality control procedures that will provide
documentation of sample integrity.
Procedure
1. Transfer 100 ml. of sample to be analyzed, or a suitable portion
containing not more than 15 mg. sulfide supplemented to 100 ml. with
distilled water, to a 250 ml. Erlenmeyer flask.
2. Adjust the sample to pH 8.5-9.5 with 6N HC1.
3. Add 20 ml. of 6M ammonium chloride buffer (pH 9.3), 1 ml. of
ferrous dimethylglyoxime indicator, and 25 ml. of 0.05M barium chloride.
Mix gently, stopper, and let stand for 10 minutes.
4. After 10 minutes titrate with standardized potassium ferricyanide
to disappearance of pink color. The endpoint is reached when there is no
reappearance of the pink color after 30 seconds.
Calculation and Reporting of Results.

----------------------------
1. mg./l. sulfide = vol. in ml. of sample
titrated
where A=volume in ml. of potassium ferricyanide solution used,
and B=normality of potassium ferricyanide solution.
2. Report results to two significant figures.
Quality Control
1. Each laboratory that uses this method is required to operate a
formal quality control program. The minimum requirements of this program
consist of an initial demonstration of laboratory capability and the
analysis of replicate and spiked samples as a continuing check on
performance. The laboratory is required to maintain performance records
to define the quality of data that is generated. Ongoing performance
checks must be compared with established performance criteria
[[Page 21]]
to determine if the results of analyses are within precision and
accuracy limits expected of the method.
2. Before performing any analyses, the analyst must demonstrate the
ability to generate acceptable precision and accuracy with this method
by performing the following operations.
(a) Perform four replicate analyses of a 20 mg./l. sulfide standard
prepared in distilled water (see paragraph 6 under ``Reagents'' above).
(b)(1) Calculate clean water precision and accuracy in accordance
with standard statistical procedures. Clean water acceptance limits are
presented in paragraph 2(b)(2) below. These criteria must be met or
exceeded before sample analyses can be initiated. A clean water standard
must be analyzed with each sample set and the established criteria met
for the analysis to be considered under control.
(2) Clean water precision and accuracy acceptance limits: For
distilled water samples containing from 5 mg./l. to 50 mg./l. sulfide,
the mean concentration from four replicate analyses must be within the
range of 50 to 110 percent of the true value.
3. The Method Detection Limits (MDL) should be determined
periodically by each participating laboratory in accordance with the
procedures specified in ``Methods for Chemical Analysis of Municipal and
Industrial Wastewater,'' EPA-660/4-82-057, July 1982, EMSL, Cincinnati,
OH 45268. For the convenience of the user, these procedures are
contained in appendix C to part 425.
4. A minimum of one spiked and one duplicate sample must be
performed for each analytical event, or five percent spikes and five
percent duplicates when the number of samples per event exceeds twenty.
Spike levels are to be at the MDL (see paragraph 3 above for MDL
samples) and at x where x is the concentration found if in excess of the
MDL. Spike recovery must be 40 to 120 percent for the analysis of a
particular matrix type to be considered valid. If a sample or matrix
type provides performance outside these acceptance limits, the analyses
must be repeated using the modified Monier-Williams procedures described
in appendix B to this part.
5. Report results in mg./liter. When duplicate and spiked samples
are analyzed, report all data with the sample results.
[53 FR 9183, Mar. 21, 1988]
Appendix B to Part 425--Modified Monier-Williams Method
Outline of Method
Hydrogen sulfide is liberated from an acidified sample by
distillation and purging with nitrogen gas (N2). Sulfur
dioxide interference is removed by scrubbing the nitrogen gas stream in
a pH 7 buffer solution. The sulfide gas is collected by passage through
an alkaline hydrogen peroxide scrubbing solution in which it is oxidized
to sulfate. Sulfate concentration in the scrubbing solution is
determined by either EPA gravimetric test procedure 375.3 or EPA
turbidimetric test procedure 375.4 (see 40 CFR 136.3, Table IB,
parameter 65 (49 FR 43234, October 26, 1984, and correction notice at 50
FR 690, January 4, 1985)).

Reagents
1. Potassium hydroxide, 6N: Dissolve 340 g. of analytical reagent
grade KOH in 1 liter distilled water.
2. Sodium hydroxide, 6N: Dissolve 240 g. of analytical reagent grade
NaOH in 1 liter distilled water.
3. Sodium hydroxide, 0.03N: Dilute 5.0 ml. of 6N NaOH to 1 liter
with distilled water.
4. Hydrochloric acid, 6N: Dilute 500 ml. of concentrated HCl to 1
liter with distilled water.
5. Potassium phosphate stock buffer, 0.5M: Dissolve 70 g. of
monobasic potassium phosphate in approximately 800 ml. distilled water.
Adjust pH to 7.0 0.1 with 6N potassium hydroxide and dilute
to 1 liter with distilled water. Stock solution in stable for several
months at 4 deg.C.
6. Potassium phosphate buffer, 0.05M: Dilute 1 volume of 0.5M
potassium phosphate stock buffer with 9 volumes of distilled water.
Solution is stable for one month at 4 deg.C.
7. Alkaline 3% hydrogen peroxide: Dilute 1 volume of 30 percent
hydrogen peroxide with 9 volumes of 0.03N NaOH. Prepare this solution
fresh each day of use.
8. Preparation of stock sulfide standard, 1000 ppm.: Dissolve 2.4 g.
reagent grade sodium sulfide in 1 liter of distilled water. Store in a
tightly stoppered container. Diluted working standards must be prepared
fresh daily and their concentrations determined by EPA test procedure
376.1 immediately prior to use (see 40 CFR 136.3, Table IB, parameter 66
(49 FR 43234, October 26, 1984, and correction notice at 50 FR 690,
January 4, 1985)).
Sample Preservation and Storage
Preserve unfiltered wastewater samples immediately after collection
by adjustment to pH>9 with 6N NaOH and addition of 2 ml. of 2N zinc
acetate per liter. This amount of zinc acetate is adequate to preserve
64 mg./l. sulfide under ideal conditions. Sample containers must be
covered tightly and stored at 4 deg.C until analysis. Samples must be
analyzed within seven days of collection. If these procedures cannot be
achieved, it is the laboratory's responsibility to institute quality
control procedures that will provide documentation of sample integrity.
Procedure (See Figure 1 for apparatus layout.)
1. Place 50 ml. of 0.05M pH 7.0 potassium phosphate buffer in Trap
No. 1.
2. Place 50 ml. of alkaline 3 percent hydrogen peroxide in Trap No.
2.
3. Sample introduction and N2 prepurge: Gently mix sample
to be analyzed to resuspend settled material, taking care not to aerate
the sample. Transfer 400 ml. of sample, or a suitable portion containing
not more than 20 mg. sulfide diluted to 400 ml. with distilled water, to
the distillation flask. Adjust the N2 flow so that the
impingers are frothing vigorously, but not overflowing. Vaccum may be
applied at the outlet of Trap No. 2 to assist in smooth purging. The
N2 inlet tube of the distillation flask must be submerged
deeply in the sample to ensure efficient agitation. Purge the sample for
30 minutes without applying heat. Test the apparatus for leaks during
the prepurge cycle (Snoop or soap water solution).
4. Volatilization of H2S: Interrupt the N2
flow (and vacuum) and introduce 100 ml. of 6N HCl to the sample using
the separatory funnel. Immediately resume the gas flow (and vacuum).
Apply maximum heat with the heating mantle until the sample begins to
boil, then reduce heat and maintain gentle boiling and N2
flow for 30 minutes. Terminate the distillation cycle by turning off the
heating mantle and maintaining N2 flow through the system for
5 to 10 minutes. Then turn off the N2 flow (and release
vacuum) and cautiously vent the system by placing 50 to 100 ml. of
distilled water in the separatory funnel and opening the stopcock
carefully. When the bubbling stops and the system is equalized to
atmospheric pressure, remove the separatory funnel. Extreme care must be
exercised in terminating the distillation cycle to avoid flash-over,
draw-back, or violent steam release.
5. Analysis: Analyze the contents of Trap No. 2 for sulfate
according to either EPA gravimetric test procedure 375.3 or EPA
turbidimetric test procedure 375.4 (see 40 CFR 136.3, Table IB,
parameter 65 (49 FR 43234, October 26, 1984, and correction notice at 50
FR 690, January 4, 1985)). Use the result to calculate mg./l. of sulfide
in wastewater sample.

presented in paragraph 2(b)(2) below. These criteria must be met or
exceeded before sample analyses can be initiated. A clean water standard
must be analyzed with each sample set and the established criteria met
for the analyses to be considered under control.
(2) Clean water precision and accuracy acceptance limits: For
distilled water samples containing from 5 mg./l. to 50 mg./l. sulfide,
the mean concentration from four replicate analyses must be within the
range of 72 to 114 percent of the true value.
3. The Method Detection Limit (MDL) should be determined
periodically by each participating laboratory in accordance with the
procedures specified in ``Methods for Chemical Analysis of Municipal and
Industrial Wastewater,'' EPA-600/4-82-057, July 1982, EMSL, Cincinnati,
OH 45268. For the convenience of the user, these procedures are
contained in appendix C to part 425.

This procedure is designed for applicability to a wide variety of
sample types ranging from reagent (blank) water containing analyte to
wastewater containing analyte. The MDL for an analytical procedure may
vary as a function of sample type. The procedure requires a complete,
specific and well defined analytical method. It is essential that all
sample processing steps of the analytical method be included in the
determination of the method detection limit.
The MDL obtained by this procedure is used to judge the significance
of a single measurement of a future sample.
The MDL procedure was designed for applicability to a broad variety
of physical and chemical methods. To accomplish this, the procedure was
made device- or instrument-independent.
Procedure
1. Make an estimate of the detection limit using one of the
following:
(a) The concentration value that corresponds to an instrument
signal/noise ratio in the range of 2.5 to 5. If the criteria for
qualitative identification of the analyte is based upon pattern
recognition techniques, the least abundant signal necessary to achieve
identification must be considered in making the estimate.
(b) The concentration value that corresponds to three times the
standard deviation of replicate instrumental measurements for the
analyte in reagent water.
(c) The concentration value that corresponds to the region of the
standard curve
[[Page 25]]
where there is a significant change in sensitivity at low analyte
concentrations, i.e., a break in the slope of the standard curve.
(d) The concentration value that corresponds to known instrumental
limitations.
It is recognized that the experience of the analyst is important to
this process. However, the analyst must include the above considerations
in the estimate of the detection limit.
2. Prepare reagent (blank) water that is as free of analyte as
possible. Reagent or interference free water is defined as a water
sample in which analyte and interferent concentrations are not detected
at the method detection limit of each analyte of interest. Interferences
are defined as systematic errors in the measured analytical signal of an
established procedure caused by the presence of interfering species
(interferent). The interferent concentration is presupposed to be
normally distributed in representative samples of a given matrix.
3. (a) If the MDL is to be determined in reagent water (blank),
prepare a laboratory standard (analyte in reagent water) at a
concentration which is at least equal to or in the same concentration
range as the estimated MDL. (Recommended between 1 and 5 times the
estimated MDL.) Proceed to Step 4.
(b) If the MDL is to be determined in another sample matrix, analyze
the sample. If the measured level of the analyte is in the recommended
range of one to five times the estimated MDL, proceed to Step 4.
If the measured concentration of analyte is less than the estimated
MDL, add a known amount of analyte to bring the concentration of analyte
to between one and five times the MDL. In the case where an interference
is coanalyzed with the analyte:
If the measured level of analyte is greater than five times the
estimated MDL, there are two options:
(1) Obtain another sample of lower level of analyte in same matrix
if possible.
(2) The sample may be used as is for determining the MDL if the
analyte level does not exceed 10 times the MDL of the analyte in reagent
water. The variance of the analytical method changes as the analyte
concentration increases from the MDL, hence the MDL determined under
these circumstances may not truly reflect method variance at lower
analyte concentrations.
4. (a) Take a minimum of seven aliquots of the sample to be used to
calculate the MDL and process each through the entire anlaytical method.
Make all computations according to the defined method with final results
in the method reporting units. If blank measurements are required to
calculate the measured level of analyte, obtain separate blank
measurements for each sample aliquot anlayzed. The average blank
measurement is subtracted from the respective sample measurements.
(b) It may be economically and technically desirable to evaluate the
estimated MDL before proceeding with 4a. This will: (1) Prevent
repeating this entire procedure when the costs of analyses are high and
(2) insure that the procedure is being conducted at the correct
concentration. It is quite possible that an incorrect MDL can be
calculated from data obtained at many times the real MDL even though the
background concentration of analyte is less than five times the
calculated MDL. To insure that the estimate of the MDL is a good
estimate, it is necessary to determine that a lower concentration of
analyte will not result in a significantly lower MDL. Take two aliquots
of the sample to be used to calculate the MDL and process each through
the entire method, including blank measurements as described above in
4a. Evaluate these data:
(1) If these measurements indicate the sample is in the desirable
range for determining the MDL, take five additional aliquots and
proceed. Use all seven measurements to calculate the MDL.
(2) If these measurements indicate the sample is not in the correct
range, reestimate the MDL, obtain new sample as in 3 and repeat either
4a or 4b.
5. Calculate the variance (S2) and standard deviation (S)
of the replicate measurements, as follows:
where: the xi, i = 1 to n are the analytical results in the
final method reporting units obtained from the n sample
aliquots and
refers to the sum of the X values from i = 1 to n.
6. (a) Compute the MDL as follows:
MDL = t(n-1, 1-a = .99) (S)
where:
MDL=the method detection
t(n-1, 1-a=.99)=the students' t value appropriate for a 99
percent confidence level and a standard deviation estimate
with n-1 degrees of freedom. See Table.
S=standard deviation of the replicate analyses.
(b) The 95 percent confidence limits for the MDL derived in 6a are
computed according
[[Page 26]]
to the following equations derived from percentiles of the chi square
over degrees of freedom distribution (X2/df) and calculated as follows:
MDLLCL=0.69 MDL
MDLUCL=1.92 MDL where MDLLCL and MDLUCL
are the lower and upper 95 percent confidence limits
respectively based on seven aliquots.
7. Optional iterative procedure to verify the reasonableness of the
estimated MDL and calculated MDL of subsequent MDL determinations.
(a) If this is the initial attempt to compute MDL based on the
estimated MDL in Step 1, take the MDL as calculated in Step 6, spike in
the matrix at the calculated MDL and proceed through the procedure
starting with Step 4.
(b) If the current MDL determination is an iteration of the MDL
procedure for which the spiking level does not permit qualitative
identification, report the MDL as that concentration between the current
spike level and the previous spike level which allows qualitative
identification.
(c) If the current MDL determination is an iteration of the MDL
procedure and the spiking level allows qualitative identification, use
S2 from the current MDL calculation and S2 from
the previous MDL calculation to compute the F ratio.
then compute the pooled standard deviation by the following equation:
respike at the last calculated MDL and process the samples through the
procedure starting with Step 4.
(d) Use the Spooled as calculated in 7b to compute the
final MDL according to the following equation:
MDL=2.681 (Spooled)
where 2.681 is equal to t (12, 1-a=.99)
(e) The 95 percent confidence limits for MDL derived in 7c are
computed according to the following equations derived from percentiles
of the chi squared over degrees of freedom distribution.
MDLLCL=0.72 MDL
MDLUCL=1.65 MDL
where LCL and UCL are the lower and upper 95 percent confidence limits
respectively based on 14 aliquots.
Reporting
The analytical method used must be specifically identified by number
or title and the MDL for each analyte expressed in the appropriate
method reporting units. If the analytical method permits options which
affect the method detection limit, these conditions must be specified
with the MDL value. The sample matrix used to determine the MDL must
also be identified with the MDL value. Report the mean analyte level
with the MDL. If a laboratory standard or a sample that contained a
known amount analyte was used for this determination, report the mean
recovery, and indicate if the MDL determination was iterated.
If the level of the analyte in the sample matrix exceeds 10 times
the MDL of the analyte in reagent water, do not report a value for the
MDL.
