                               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, 2007), 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, 2001, consult either the List of CFR Sections Affected, 1949-
1963, 1964-1972, 1973-1985, or 1986-2000, published in 11 separate 
volumes. For the period beginning January 1, 2001, 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 202-741-6010.

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 Statutory 
Authorities and Agency Rules (Table I). 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.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

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 standards for sulfide than those 
established by this part without EPA approval.
    (b) The pretreatment standards for sulfide established by this part 
will not

[[Page 8]]

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.
    (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

[[Page 9]]

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.

     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.

                                Reagents

    1. Preparation of 0.02N potassium ferricyanide; Weigh to the nearest 
tenth of a gram

[[Page 20]]

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:
[GRAPHIC] [TIFF OMITTED] TR25SE06.000

    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.

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 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

    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.

[[Page 23]]

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 pH9 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 H2 S: 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.

                             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 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 accuracy and precision by performing the 
following operations.

[[Page 24]]

    (a) Perform four replicate analyses of a 20 mg./l. sulfide standard 
prepared in distilled water (see paragraph 8 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 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.
    4. A minimum of one spiked and one duplicate sample must be run 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 when x is the concentration found if in excess of the MDL. Spike 
recovery must be 60 to 120 percent for the analysis of a particular 
matrix type to be considered valid.
    5. Report all results in mg./liter. When duplicate and spiked 
samples are analyzed, report all data with the sample results.

 Appendix C to Part 425--Definition and Procedure for the Determination 
                    of the Method Detection Limit \1\

    The method detection limit (MDL) is defined at the minimum 
concentration of a substance that can be identified, measured and 
reported with 99 percent confidence that the analyte concentration is 
greater than zero and determined from analysis of a sample in a given 
matrix containing analyte.

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

                          Scope and Application

    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 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.

[[Page 25]]

    (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 (S\2\) 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 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 
S\2\ from the current MDL calculation and S\2\ from the previous MDL 
calculation to compute the F ratio.

[[Page 26]]



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.

establishes the quantity or quality of pollutants or pollutant 
properties controlled by this section which may be discharged to a 
publicly owned treatment works by a new point source subject to the 
provisions of this subpart. Because of the recognition that animal and 
vegetable oils can be adequately removed in a publicly owned treatment 
works, whereas mineral oil may not be readily removed and may pass 
through untreated, two separate limitations are established.

Sec. 426.126  Pretreatment standards for new sources.

    Any new source subject to this subpart that introduces process 
wastewater pollutants into a publicly owned treatment works must comply 
with 40 CFR part 403. In addition, the following pretreatment standard 
establishes the quantity or quality of pollutants or pollutant 
properties controlled by this section which may be discharged to a 
publicly owned treatment works by a new point source subject to the 
provisions of this subpart. Because of the recognition that animal and 
vegetable oils can be adequately removed in a publicly owned treatment 
works, whereas mineral oil may not be readily removed and may pass 
through untreated, two separate limitations are established.

pollutants to the waters of the United States, or which introduces or 
may introduce process wastewater pollutants into a publicly owned 
treatment works.



Sec. 429.11  General definitions.

    In addition to the definitions set forth in 40 CFR part 401, the 
following definitions apply to this part:
    (a) The term ``hydraulic barking'' means a wood processing operation 
that removes bark from wood by the use of water under a pressure of 6.8 
atm (100 psia) or greater.
    (b) The terms ``cubic feet'' or ``cubic meters'' of production in 
subpart A means the cubic feet or cubic meters of logs from which bark 
is removed.
    (c) The term ``process wastewater'' specifically excludes non-
contact cooling water, material storage yard runoff (either raw material 
or processed wood storage), boiler blowdown, and wastewater from washout 
of thermal oxidizers or catalytic oxidizers, wastewater from biofilters, 
or wastewater from wet electrostatic precipitators used upstream of 
thermal oxidizers or catalytic oxidizers installed by facilities covered 
by subparts B, C, D or M to comply with the national emissions standards 
for hazardous air pollutants (NESHAP) for plywood and composite

[[Page 87]]

wood products (PCWP) facilities (40 CFR part 63, subpart DDDD). For the 
dry process hardboard, veneer, finishing, particleboard, and sawmills 
and planing mills subcategories, fire control water is excluded from the 
definition.
    (d) The term ``gross production of fiberboard products'' means the 
air dry weight of hardboard or insulation board following formation of 
the mat and prior to trimming and finishing operations.
    (e) The term ``hardboard'' means a panel manufactured from 
interfelted ligno-cellulosic fibers consolidated under heat and pressure 
to a density of 0.5 g/cu cm (31 lb/cu ft) or greater.
    (f) The term ``insulation board'' means a panel manufactured from 
interfelted ligno-cellulosic fibers consolidated to a density of less 
than 0.5 g/cu cm (less than 31 lb/cu ft).
    (g) The term ``smooth-one-side (S1S) hardboard'' means hardboard 
which is produced by the wet-matting, wet-pressing process.
    (h) The term ``smooth-two-sides (S2S) hardboard'' means hardboard 
which is produced by the wet-matting, dry-pressing process.
    (i) The term ``debris'' means woody material such as bark, twigs, 
branches, heartwood or sapwood that will not pass through a 2.54 cm (1.0 
in) diameter round opening and is present in the discharge from a wet 
storage facility.
    (j) For the subcategories for which numerical limitations are given, 
the daily maximum limitation is a value that should not be exceeded by 
any one effluent measurement. The 30-day limitation is a value that 
should not be exceeded by the average of daily measurements taken during 
any 30-day period.

\a\ This subpart is contained in the 40 CFR parts 425 through 699, edition revised as of July 1, 1997.



Sec. 430.01  General definitions.

    In addition to the definitions set forth in 40 CFR part 401 and 40 
CFR 403.3, the following definitions apply to this part:
    (a) Adsorbable organic halides (AOX). A bulk parameter that measures 
the total mass of chlorinated organic matter in water and wastewater.
    (b) Annual average. The mean concentration, mass loading or 
production-normalized mass loading of a pollutant over a period of 365 
consecutive days (or such other period of time determined by the 
permitting authority to be sufficiently long to encompass expected 
variability of the concentration, mass loading, or production-normalized 
mass loading at the relevant point of measurement).
    (c) Bleach plant. All process equipment used for bleaching beginning 
with the first application of bleaching agents (e.g., chlorine, chlorine 
dioxide, ozone, sodium or calcium hypochlorite, or peroxide), each 
subsequent extraction stage, and each subsequent stage where bleaching 
agents are applied to the pulp. For mills in subpart E of this part 
producing specialty grades of pulp, the bleach plant includes process 
equipment used for the hydrolysis or extraction stages prior to the 
first application of bleaching agents. Process equipment used for oxygen 
delignification prior to the application of bleaching agents is not part 
of the bleach plant.
    (d) Bleach plant effluent. The total discharge of process 
wastewaters from the bleach plant from each physical bleach line 
operated at the mill, comprising separate acid and alkaline filtrates or 
the combination thereof.
    (e) Chemical oxygen demand (COD). A bulk parameter that measures the 
oxygen-consuming capacity of organic and inorganic matter present in 
water or wastewater. It is expressed as the amount of oxygen consumed 
from a chemical oxidant in a specific test.
    (f) Elemental chlorine-free (ECF). Any process for bleaching pulps 
in the absence of elemental chlorine and hypochlorite that uses 
exclusively chlorine dioxide as the only chlorine-containing bleaching 
agent.
    (g) End of the pipe. The point at which final mill effluent is 
discharged to waters of the United States or introduced to a POTW.
    (h) Fiber line. A series of operations employed to convert wood or 
other fibrous raw material into pulp. If the final product is bleached 
pulp, the fiber line encompasses pulping, de-knotting, brownstock 
washing, pulp screening, centrifugal cleaning, and multiple bleaching 
and washing stages.
    (i) Minimum level (ML). The level at which the analytical system 
gives recognizable signals and an acceptable

[[Page 105]]

calibration point. The following minimum levels apply to pollutants in 
this part:

    (j) New source. (1) Notwithstanding the criteria codified at 40 CFR 
122.29(b)(1), a source subject to subpart B or E of this part is a ``new 
source'' if it meets the definition of ``new source'' at 40 CFR 122.2 
and:
    (i) It is constructed at a site at which no other source is located; 
or
    (ii) It totally replaces the process or production equipment that 
causes the discharge of pollutants at an existing source, including the 
total replacement of a fiber line that causes the discharge of 
pollutants at an existing source, except as provided in paragraph (j)(2) 
of this section; or
    (iii) Its processes are substantially independent of an existing 
source at the same site. In determining whether these processes are 
substantially independent, the Director shall consider such factors as 
the extent to which the new facility is integrated with the existing 
plant; and the extent to which the new facility is engaged in the same 
general type of activity as the existing source.
    (2) The following are examples of changes made by mills subject to 
subparts B or E of this part that alone do not cause an existing mill to 
become a ``new source'':
    (i) Upgrades of existing pulping operations;
    (ii) Upgrades or replacement of pulp screening and washing 
operations;
    (iii) Installation of extended cooking and/or oxygen delignification 
systems or other post-digester, pre-bleaching delignification systems;
    (iv) Bleach plant modifications including changes in methods or 
amounts of chemical applications, new chemical applications, 
installation of new bleaching towers to facilitate replacement of sodium 
or calcium hypochlorite, and installation of new pulp washing systems; 
or
    (v) Total replacement of process or production equipment that causes 
the discharge of pollutants at an existing source (including a 
replacement fiber line), but only if such replacement is performed for 
the purpose of achieving limitations that have been included in the 
discharger's NPDES permit pursuant to Sec. 430.24(b).
    (k) Non-continuous discharger. (1) Except as provided in paragraph 
(k)(2) of this section, a non-continuous discharger is a mill which is 
prohibited by the NPDES authority from discharging pollutants during 
specific periods of time for reasons other than treatment plant upset 
control, such periods being at least 24 hours in duration. A mill shall 
not be deemed a non-continuous discharger unless its permit, in addition 
to setting forth the prohibition described above, requires compliance 
with the effluent limitations established for non-continuous dischargers 
and also requires compliance with maximum day and average of 30 
consecutive days effluent limitations. Such maximum day and average of 
30

[[Page 106]]

consecutive days effluent limitations for non-continuous dischargers 
shall be established by the NPDES authority in the form of 
concentrations which reflect wastewater treatment levels that are 
representative of the application of the best practicable control 
technology currently available, the best conventional pollutant control 
technology, or new source performance standards in lieu of the maximum 
day and average of 30 consecutive days effluent limitations for 
conventional pollutants set forth in each subpart.
    (2) A mill is a non-continuous discharger for the purposes of 
determining applicable effluent limitations under subpart B or E of this 
part (other than conventional limits for existing sources) if, for 
reasons other than treatment plant upset control (e.g., protecting 
receiving water quality), the mill is prohibited by the NPDES authority 
from discharging pollutants during specific periods of time or if it is 
required to release its discharge on a variable flow or pollutant 
loading rate basis.
    (l) POTW. Publicly owned treatment works as defined at 40 CFR 
403.3(o).
    (m) Process wastewater. For subparts B and E only, process 
wastewater is any water that, during manufacturing or processing, comes 
into direct contact with or results from the production or use of any 
raw material, intermediate product, finished product, byproduct, or 
waste product. For purposes of subparts B and E of this part, process 
wastewater includes boiler blowdown; wastewaters from water treatment 
and other utility operations; blowdowns from high rate (e.g., greater 
than 98 percent) recycled non-contact cooling water systems to the 
extent they are mixed and co-treated with other process wastewaters; 
wastewater, including leachates, from landfills owned by pulp and paper 
mills subject to subpart B or E of this part if the wastewater is 
commingled with wastewater from the mill's manufacturing or processing 
facility; and storm waters from the immediate process areas to the 
extent they are mixed and co-treated with other process wastewaters. For 
purposes of this part, contaminated groundwaters from on-site or off-
site groundwater remediation projects are not process wastewater.
    (n) Production. (1) For all limitations and standards specified in 
this part except those pertaining to AOX and chloroform: Production 
shall be defined as the annual off-the-machine production (including 
off-the-machine coating where applicable) divided by the number of 
operating days during that year. Paper and paperboard production shall 
be measured at the off-the-machine moisture content, except for subpart 
C of this part (as it pertains to pulp and paperboard production at 
unbleached kraft mills including linerboard or bag paper and other mixed 
products, and to pulp and paperboard production using the unbleached 
kraft neutral sulfite semi-chemical (cross recovery) process), and 
subparts F and J of this part (as they pertain to paperboard production 
from wastepaper from noncorrugating medium furnish or from corrugating 
medium furnish) where paper and paperboard production shall be measured 
in air-dry-tons (10% moisture content). Market pulp shall be measured in 
air-dry tons (10% moisture). Production shall be determined for each 
mill based upon past production practices, present trends, or committed 
growth.
    (2) For AOX and chloroform limitations and standards specified in 
subparts B and E of this part: Production shall be defined as the annual 
unbleached pulp production entering the first stage of the bleach plant 
divided by the number of operating days during that year. Unbleached 
pulp production shall be measured in air-dried-metric-tons (10% 
moisture) of brownstock pulp entering the bleach plant at the stage 
during which chlorine or chlorine-containing compounds are first applied 
to the pulp. In the case of bleach plants that use totally chlorine free 
bleaching processes, unbleached pulp production shall be measured in 
air-dried-metric tons (10% moisture) of brownstock pulp entering the 
first stage of the bleach plant from which wastewater is discharged. 
Production shall be determined for each mill based upon past production 
practices, present trends, or committed growth.
    (o) TCDD. 2,3,7,8-tetrachlorodibenzo-p-dioxin.

[[Page 107]]

    (p) TCDF. 2,3,7,8-tetrachlorodibenzofuran.
    (q) Totally chlorine-free (TCF) bleaching. Pulp bleaching operations 
that are performed without the use of chlorine, sodium hypochlorite, 
calcium hypochlorite, chlorine dioxide, chlorine monoxide, or any other 
chlorine-containing compound.
    (r) Wet Barking. Wet barking operations shall be defined to include 
hydraulic barking operations and wet drum barking operations which are 
those drum barking operations that use substantial quantities of water 
in either water sprays in the barking drums or in a partial submersion 
of the drums in a ``tub'' of water.

Sec. 430.03  Best management practices (BMPs) for spent pulping liquor, soap,
and turpentine management, spill prevention, and control.

    (a) Applicability. This section applies to direct and indirect 
discharging pulp, paper, and paperboard mills with pulp production in 
subparts B (Bleached Papergrade Kraft and Soda) and E (Papergrade 
Sulfite).
    (b) Specialized definitions--(1) Action Level: A daily pollutant 
loading that when exceeded triggers investigative or

[[Page 111]]

corrective action. Mills determine action levels by a statistical 
analysis of six months of daily measurements collected at the mill. For 
example, the lower action level may be the 75th percentile of the 
running seven-day averages (that value exceeded by 25 percent of the 
running seven-day averages) and the upper action level may be the 90th 
percentile of the running seven-day averages (that value exceeded by 10 
percent of the running seven-day averages).
    (2) Equipment Items in Spent Pulping Liquor, Soap, and Turpentine 
Service: Any process vessel, storage tank, pumping system, evaporator, 
heat exchanger, recovery furnace or boiler, pipeline, valve, fitting, or 
other device that contains, processes, transports, or comes into contact 
with spent pulping liquor, soap, or turpentine. Sometimes referred to as 
``equipment items.''
    (3) Immediate Process Area: The location at the mill where pulping, 
screening, knotting, pulp washing, pulping liquor concentration, pulping 
liquor processing, and chemical recovery facilities are located, 
generally the battery limits of the aforementioned processes. 
``Immediate process area'' includes spent pulping liquor storage and 
spill control tanks located at the mill, whether or not they are located 
in the immediate process area.
    (4) Intentional Diversion: The planned removal of spent pulping 
liquor, soap, or turpentine from equipment items in spent pulping 
liquor, soap, or turpentine service by the mill for any purpose 
including, but not limited to, maintenance, grade changes, or process 
shutdowns.
    (5) Mill: The owner or operator of a direct or indirect discharging 
pulp, paper, or paperboard manufacturing facility subject to this 
section.
    (6) Senior Technical Manager: The person designated by the mill 
manager to review the BMP Plan. The senior technical manager shall be 
the chief engineer at the mill, the manager of pulping and chemical 
recovery operations, or other such responsible person designated by the 
mill manager who has knowledge of and responsibility for pulping and 
chemical recovery operations.
    (7) Soap: The product of reaction between the alkali in kraft 
pulping liquor and fatty acid portions of the wood, which precipitate 
out when water is evaporated from the spent pulping liquor.
    (8) Spent Pulping Liquor: For kraft and soda mills ``spent pulping 
liquor'' means black liquor that is used, generated, stored, or 
processed at any point in the pulping and chemical recovery processes. 
For sulfite mills ``spent pulping liquor'' means any intermediate, 
final, or used chemical solution that is used, generated, stored, or 
processed at any point in the sulfite pulping and chemical recovery 
processes (e.g., ammonium-, calcium-, magnesium-, or sodium-based 
sulfite liquors).
    (9) Turpentine: A mixture of terpenes, principally pinene, obtained 
by the steam distillation of pine gum recovered from the condensation of 
digester relief gases from the cooking of softwoods by the kraft pulping 
process. Sometimes referred to as sulfate turpentine.
    (c) Requirement to implement Best Management Practices. Each mill 
subject to this section must implement the Best Management Practices 
(BMPs) specified in paragraphs (c)(1) through (10) of this section. The 
primary objective of the BMPs is to prevent leaks and spills of spent 
pulping liquors, soap, and turpentine. The secondary objective is to 
contain, collect, and recover at the immediate process area, or 
otherwise control, those leaks, spills, and intentional diversions of 
spent pulping liquor, soap, and turpentine that do occur. BMPs must be 
developed according to best engineering practices and must be 
implemented in a manner that takes into account the specific 
circumstances at each mill. The BMPs are as follows:
    (1) The mill must return spilled or diverted spent pulping liquors, 
soap, and turpentine to the process to the maximum extent practicable as 
determined by the mill, recover such materials outside the process, or 
discharge spilled or diverted material at a rate that does not disrupt 
the receiving wastewater treatment system.

[[Page 112]]

    (2) The mill must establish a program to identify and repair leaking 
equipment items. This program must include:
    (i) Regular visual inspections (e.g., once per day) of process areas 
with equipment items in spent pulping liquor, soap, and turpentine 
service;
    (ii) Immediate repairs of leaking equipment items, when possible. 
Leaking equipment items that cannot be repaired during normal operations 
must be identified, temporary means for mitigating the leaks must be 
provided, and the leaking equipment items repaired during the next 
maintenance outage;
    (iii) Identification of conditions under which production will be 
curtailed or halted to repair leaking equipment items or to prevent 
pulping liquor, soap, and turpentine leaks and spills; and
    (iv) A means for tracking repairs over time to identify those 
equipment items where upgrade or replacement may be warranted based on 
frequency and severity of leaks, spills, or failures.
    (3) The mill must operate continuous, automatic monitoring systems 
that the mill determines are necessary to detect and control leaks, 
spills, and intentional diversions of spent pulping liquor, soap, and 
turpentine. These monitoring systems should be integrated with the mill 
process control system and may include, e.g., high level monitors and 
alarms on storage tanks; process area conductivity (or pH) monitors and 
alarms; and process area sewer, process wastewater, and wastewater 
treatment plant conductivity (or pH) monitors and alarms.
    (4) The mill must establish a program of initial and refresher 
training of operators, maintenance personnel, and other technical and 
supervisory personnel who have responsibility for operating, 
maintaining, or supervising the operation and maintenance of equipment 
items in spent pulping liquor, soap, and turpentine service. The 
refresher training must be conducted at least annually and the training 
program must be documented.
    (5) The mill must prepare a brief report that evaluates each spill 
of spent pulping liquor, soap, or turpentine that is not contained at 
the immediate process area and any intentional diversion of spent 
pulping liquor, soap, or turpentine that is not contained at the 
immediate process area. The report must describe the equipment items 
involved, the circumstances leading to the incident, the effectiveness 
of the corrective actions taken to contain and recover the spill or 
intentional diversion, and plans to develop changes to equipment and 
operating and maintenance practices as necessary to prevent recurrence. 
Discussion of the reports must be included as part of the annual 
refresher training.
    (6) The mill must establish a program to review any planned 
modifications to the pulping and chemical recovery facilities and any 
construction activities in the pulping and chemical recovery areas 
before these activities commence. The purpose of such review is to 
prevent leaks and spills of spent pulping liquor, soap, and turpentine 
during the planned modifications, and to ensure that construction and 
supervisory personnel are aware of possible liquor diversions and of the 
requirement to prevent leaks and spills of spent pulping liquors, soap, 
and turpentine during construction.
    (7) The mill must install and maintain secondary containment (i.e., 
containment constructed of materials impervious to pulping liquors) for 
spent pulping liquor bulk storage tanks equivalent to the volume of the 
largest tank plus sufficient freeboard for precipitation. An annual tank 
integrity testing program, if coupled with other containment or 
diversion structures, may be substituted for secondary containment for 
spent pulping liquor bulk storage tanks.
    (8) The mill must install and maintain secondary containment for 
turpentine bulk storage tanks.
    (9) The mill must install and maintain curbing, diking or other 
means of isolating soap and turpentine processing and loading areas from 
the wastewater treatment facilities.
    (10) The mill must conduct wastewater monitoring to detect leaks and 
spills, to track the effectiveness of the BMPs, and to detect trends in 
spent pulping liquor losses. Such monitoring must be performed in 
accordance with paragraph (i) of this section.

[[Page 113]]

    (d) Requirement to develop a BMP Plan. (1) Each mill subject to this 
section must prepare and implement a BMP Plan. The BMP Plan must be 
based on a detailed engineering review as described in paragraphs (d)(2) 
and (3) of this section. The BMP Plan must specify the procedures and 
the practices required for each mill to meet the requirements of 
paragraph (c) of this section, the construction the mill determines is 
necessary to meet those requirements including a schedule for such 
construction, and the monitoring program (including the statistically 
derived action levels) that will be used to meet the requirements of 
paragraph (i) of this section. The BMP Plan also must specify the period 
of time that the mill determines the action levels established under 
paragraph (h) of this section may be exceeded without triggering the 
responses specified in paragraph (i) of this section.
    (2) Each mill subject to this section must conduct a detailed 
engineering review of the pulping and chemical recovery operations--
including but not limited to process equipment, storage tanks, pipelines 
and pumping systems, loading and unloading facilities, and other 
appurtenant pulping and chemical recovery equipment items in spent 
pulping liquor, soap, and turpentine service--for the purpose of 
determining the magnitude and routing of potential leaks, spills, and 
intentional diversions of spent pulping liquors, soap, and turpentine 
during the following periods of operation:
    (i) Process start-ups and shut downs;
    (ii) Maintenance;
    (iii) Production grade changes;
    (iv) Storm or other weather events;
    (v) Power failures; and
    (vi) Normal operations.
    (3) As part of the engineering review, the mill must determine 
whether existing spent pulping liquor containment facilities are of 
adequate capacity for collection and storage of anticipated intentional 
liquor diversions with sufficient contingency for collection and 
containment of spills. The engineering review must also consider:
    (i) The need for continuous, automatic monitoring systems to detect 
and control leaks and spills of spent pulping liquor, soap, and 
turpentine;
    (ii) The need for process wastewater diversion facilities to protect 
end-of-pipe wastewater treatment facilities from adverse effects of 
spills and diversions of spent pulping liquors, soap, and turpentine;
    (iii) The potential for contamination of storm water from the 
immediate process areas; and
    (iv) The extent to which segregation and/or collection and treatment 
of contaminated storm water from the immediate process areas is 
appropriate.
    (e) Amendment of BMP Plan. (1) Each mill subject to this section 
must amend its BMP Plan whenever there is a change in mill design, 
construction, operation, or maintenance that materially affects the 
potential for leaks or spills of spent pulping liquor, turpentine, or 
soap from the immediate process areas.
    (2) Each mill subject to this section must complete a review and 
evaluation of the BMP Plan five years after the first BMP Plan is 
prepared and, except as provided in paragraph (e)(1) of this section, 
once every five years thereafter. As a result of this review and 
evaluation, the mill must amend the BMP Plan within three months of the 
review if the mill determines that any new or modified management 
practices and engineered controls are necessary to reduce significantly 
the likelihood of spent pulping liquor, soap, and turpentine leaks, 
spills, or intentional diversions from the immediate process areas, 
including a schedule for implementation of such practices and controls.
    (f) Review and certification of BMP Plan. The BMP Plan, and any 
amendments thereto, must be reviewed by the senior technical manager at 
the mill and approved and signed by the mill manager. Any person signing 
the BMP Plan or its amendments must certify to the permitting or 
pretreatment control authority under penalty of law that the BMP Plan 
(or its amendments) has been prepared in accordance with good 
engineering practices and in accordance with this regulation. The mill 
is not required to obtain approval from the permitting or pretreatment 
control authority of the BMP Plan or any amendments thereto.

[[Page 114]]

    (g) Record keeping requirements. (1) Each mill subject to this 
section must maintain on its premises a complete copy of the current BMP 
Plan and the records specified in paragraph (g)(2) of this section and 
must make such BMP Plan and records available to the permitting or 
pretreatment control authority and the Regional Administrator or his or 
her designee for review upon request.
    (2) The mill must maintain the following records for 3 years from 
the date they are created:
    (i) Records tracking the repairs performed in accordance with the 
repair program described in paragraph (c)(2) of this section;
    (ii) Records of initial and refresher training conducted in 
accordance with paragraph (c)(4) of this section;
    (iii) Reports prepared in accordance with paragraph (c)(5) of this 
section; and
    (iv) Records of monitoring required by paragraphs (c)(10) and (i) of 
this section.
    (h) Establishment of wastewater treatment system influent action 
levels. (1) Each mill subject to this section must conduct a monitoring 
program, described in paragraph (h)(2) of this section, for the purpose 
of defining wastewater treatment system influent characteristics (or 
action levels), described in paragraph (h)(3) of this section, that will 
trigger requirements to initiate investigations on BMP effectiveness and 
to take corrective action.
    (2) Each mill subject to this section must employ the following 
procedures in order to develop the action levels required by paragraph 
(h) of this section:
    (i) Monitoring parameters. The mill must collect 24-hour composite 
samples and analyze the samples for a measure of organic content (e.g., 
Chemical Oxygen Demand (COD) or Total Organic Carbon (TOC)). 
Alternatively, the mill may use a measure related to spent pulping 
liquor losses measured continuously and averaged over 24 hours (e.g., 
specific conductivity or color).
    (ii) Monitoring locations. For direct dischargers, monitoring must 
be conducted at the point influent enters the wastewater treatment 
system. For indirect dischargers monitoring must be conducted at the 
point of discharge to the POTW. For the purposes of this requirement, 
the mill may select alternate monitoring point(s) in order to isolate 
possible sources of spent pulping liquor, soap, or turpentine from other 
possible sources of organic wastewaters that are tributary to the 
wastewater treatment facilities (e.g., bleach plants, paper machines and 
secondary fiber operations).
    (3) By the date prescribed in paragraph (j)(1)(iii) of this section, 
each existing discharger subject to this section must complete an 
initial six-month monitoring program using the procedures specified in 
paragraph (h)(2) of this section and must establish initial action 
levels based on the results of that program. A wastewater treatment 
influent action level is a statistically determined pollutant loading 
determined by a statistical analysis of six months of daily 
measurements. The action levels must consist of a lower action level, 
which if exceeded will trigger the investigation requirements described 
in paragraph (i) of this section, and an upper action level, which if 
exceeded will trigger the corrective action requirements described in 
paragraph (i) of this section.
    (4) By the date prescribed in paragraph (j)(1)(vi) of this section, 
each existing discharger must complete a second six-month monitoring 
program using the procedures specified in paragraph (h)(2) of this 
section and must establish revised action levels based on the results of 
that program. The initial action levels shall remain in effect until 
replaced by revised action levels.
    (5) By the date prescribed in paragraph (j)(2) of this section, each 
new source subject to this section must complete a six-month monitoring 
program using the procedures specified in paragraph (h)(2) of this 
section and must develop a lower action level and an upper action level 
based on the results of that program.
    (6) Action levels developed under this paragraph must be revised 
using six months of monitoring data after any change in mill design, 
construction, operation, or maintenance that materially affects the 
potential for leaks or spills of spent pulping liquor, soap, or

[[Page 115]]

turpentine from the immediate process areas.
    (i) Monitoring, corrective action, and reporting requirements. (1) 
Each mill subject to this section must conduct daily monitoring of the 
influent to the wastewater treatment system in accordance with the 
procedures described in paragraph (h)(2) of this section for the purpose 
of detecting leaks and spills, tracking the effectiveness of the BMPs, 
and detecting trends in spent pulping liquor losses.
    (2) Whenever monitoring results exceed the lower action level for 
the period of time specified in the BMP Plan, the mill must conduct an 
investigation to determine the cause of such exceedance. Whenever 
monitoring results exceed the upper action level for the period of time 
specified in the BMP Plan, the mill must complete corrective action to 
bring the wastewater treatment system influent mass loading below the 
lower action level as soon as practicable.
    (3) Although exceedances of the action levels will not constitute 
violations of an NPDES permit or pretreatment standard, failure to take 
the actions required by paragraph (i)(2) of this section as soon as 
practicable will be a permit or pretreatment standard violation.
    (4) Each mill subject to this section must report to the NPDES 
permitting or pretreatment control authority the results of the daily 
monitoring conducted pursuant to paragraph (i)(1) of this section. Such 
reports must include a summary of the monitoring results, the number and 
dates of exceedances of the applicable action levels, and brief 
descriptions of any corrective actions taken to respond to such 
exceedances. Submission of such reports shall be at the frequency 
established by the NPDES permitting or pretreatment control authority, 
but in no case less than once per year.
    (j) Compliance deadlines--(1) Existing direct and indirect 
dischargers. Except as provided in paragraph (j)(2) of this section for 
new sources, indirect discharging mills subject to this section must 
meet the deadlines set forth below. Except as provided in paragraph 
(j)(2) of this section for new sources, NPDES permits must require 
direct discharging mills subject to this section to meet the deadlines 
set forth below. If a deadline set forth below has passed at the time 
the NPDES permit containing the BMP requirement is issued, the NPDES 
permit must require immediate compliance with such BMP requirement(s).
    (i) Prepare BMP Plans and certify to the permitting or pretreatment 
authority that the BMP Plan has been prepared in accordance with this 
regulation not later than April 15, 1999;
    (ii) Implement all BMPs specified in paragraph (c) of this section 
that do not require the construction of containment or diversion 
structures or the installation of monitoring and alarm systems not later 
than April 15, 1999.
    (iii) Establish initial action levels required by paragraph (h)(3) 
of this section not later than April 15, 1999.
    (iv) Commence operation of any new or upgraded continuous, automatic 
monitoring systems that the mill determines to be necessary under 
paragraph (c)(3) of this section (other than those associated with 
construction of containment or diversion structures) not later than 
April 17, 2000.
    (v) Complete construction and commence operation of any spent 
pulping liquor, collection, containment, diversion, or other facilities, 
including any associated continuous monitoring systems, necessary to 
fully implement BMPs specified in paragraph (c) of this section not 
later than April 16, 2001.
    (vi) Establish revised action levels required by paragraph (h)(4) of 
this section as soon as possible after fully implementing the BMPs 
specified in paragraph (c) of this section, but not later than January 
15, 2002.
    (2) New sources. Upon commencing discharge, new sources subject to 
this section must implement all of the BMPs specified in paragraph (c) 
of this section, prepare the BMP Plan required by paragraph (d) of this 
section, and certify to the permitting or pretreatment authority that 
the BMP Plan has been prepared in accordance with this regulation as 
required by paragraph (f) of this section, except that the action levels 
required by paragraph (h)(5) of this section must be established not 
later than 12 months after commencement of discharge,

[[Page 116]]

based on six months of monitoring data obtained prior to that date in 
accordance with the procedures specified in paragraph (h)(2) of this 
section.
    (k) The provisions of paragraphs (c) through (j) of this section do 
not apply to the bleached papergrade kraft mill, commonly known as the 
Androscoggin Mill, that is owned by International Paper and located in 
Jay, Maine. In lieu of imposing the requirements specified in those 
paragraphs, the permitting authority shall establish conditions for the 
discharge of COD and color for this mill on the basis of best 
professional judgment.

        Subpart B_Bleached Papergrade Kraft and Soda Subcategory



Sec. 430.20  Applicability; description of the bleached papergrade kraft and soda subcategory.

    The provisions of this subpart apply to discharges resulting from: 
The production of market pulp at bleached kraft mills; the integrated 
production of paperboard, coarse paper, and tissue paper at bleached 
kraft mills; the integrated production of pulp and fine papers at 
bleached kraft mills; and the integrated production of pulp and paper at 
soda mills.



Sec. 430.21  Specialized definitions.

    (a) The general definitions, abbreviations, and methods of analysis 
set forth in 40 CFR part 401 and Sec. 430.01 of this part apply to this 
subpart.
    (b) Baseline BAT limitations or NSPS means the BAT limitations 
specified in Sec. 430.24(a) (1) or (2), as applicable, and the NSPS 
specified in Sec. 430.25(b) (1) or (2), as applicable, that apply to 
any direct discharger that is not ``enrolled'' in the ``Voluntary 
Advanced Technology Incentives Program.''
    (c) Enroll means to notify the permitting authority that a mill 
intends to participate in the ``Voluntary Advanced Technology Incentives 
Program.'' A mill can enroll by indicating its intention to participate 
in the program either as part of its application for a National 
Pollutant Discharge Elimination System (NPDES) permit, or through 
separate correspondence to the permitting authority as long as the mill 
signs the correspondence in accordance with 40 CFR 122.22.
    (d) Existing effluent quality means the level at which the 
pollutants identified in Sec. 430.24(a)(1) are present in the effluent 
of a mill ``enrolled'' in the ``Voluntary Advanced Technology Incentives 
Program.''
    (e) Kappa number is a measure of the lignin content in unbleached 
pulp, determined after pulping and prior to bleaching.
    (f) Voluntary Advanced Technology Incentives Program is the program 
established under Sec. 430.24(b) (for existing direct dischargers) and 
Sec. 430.25(c) (for new direct dischargers) whereby participating mills 
agree to accept enforceable effluent limitations and conditions in their 
NPDES permits that are more stringent than the ``baseline BAT 
limitations or NSPS'' that would otherwise apply, in exchange for 
regulatory- and enforcement-related rewards and incentives.



Sec. 430.22  Effluent limitations representing the degree of effluent reduction 
attainable by the application of the best practicable control technology 
          currently available (BPT).

    (a) Except as provided in 40 CFR 125.30 through 125.32, any existing 
point source subject to this subpart must achieve the following effluent 
limitations representing the degree of effluent reduction attainable by 
the application of the best practicable control technology currently 
available (BPT):

Sec. 430.35  New source performance standards (NSPS).

    Any new source subject to this subpart must achieve the following 
new source performance standards (NSPS), except that non-continuous 
dischargers shall not be subject to the maximum day and average of 30 
consecutive days effluent limitations for BOD5 and TSS, but shall be 
subject to annual average effluent limitations. Also, for non-continuous 
dischargers, concentration limitations (mg/l) shall apply, where 
provided. Concentration limitations will only apply to non-continuous 
dischargers. Only facilities where chlorophenolic-containing biocides 
are used shall be subject to pentachlorophenol and trichlorophenol 
limitations. Permittees not using chlorophenolic-containing biocides 
must certify to the permit-issuing authority that they are not using 
these biocides:

Sec. 430.45  New source performance standards (NSPS).

    Any new source subject to this subpart must achieve the following 
new source performance standards (NSPS), except that non-continuous 
dischargers shall not be subject to the maximum day and average of 30 
consecutive days effluent limitations for BOD5 and TSS, but shall be 
subject to annual average effluent limitations. Also, for non-continuous 
dischargers, concentration limitations (mg/l) shall apply, where 
provided. Concentration limitations will only apply to non-continuous 
dischargers. Only facilities where chlorophenolic-containing biocides 
are used shall be subject to pentachlorophenol and trichlorophenol 
limitations. Permittees not using chlorophenolic-containing biocides 
must certify to the permit-issuing authority that they are not using 
these biocides:

                Subpart E_Papergrade Sulfite Subcategory



Sec. 430.50  Applicability; description of the papergrade sulfite subcategory.

    The provisions of this subpart apply to discharges resulting from 
the: Integrated production of pulp and paper at papergrade sulfite 
mills, where blow pit pulp washing techniques are used; and the 
integrated production of pulp and paper at papergrade sulfite mills 
where vacuum or pressure drums are used to wash pulp.



Sec. 430.51  Specialized definitions.

    (a) Except as provided in paragraphs (b) and (c) of this section, 
the general definitions, abbreviations, and methods of analysis set 
forth in 40 CFR part 401 and Sec. 430.01 of this part apply to this 
subpart.
    (b) Sulfite cooking liquor is defined as bisulfite cooking liquor 
when the pH of the liquor is between 3.0 and 6.0 and as acid sulfite 
cooking liquor when the pH is less than 3.0.
    (c) For this subpart, the segments for the papergrade sulfite 
subcategory are defined as follows:
    (1) The calcium-, magnesium-, or sodium-based sulfite pulp segment 
consists of papergrade sulfite mills where pulp and paper are produced 
using an acidic cooking liquor of calcium, magnesium, or sodium sulfite, 
unless those mills are specialty grade sulfite mills;
    (2) The ammonium-based sulfite pulp segment consists of papergrade 
sulfite mills where pulp and paper are produced using an acidic cooking 
liquor of ammonium sulfite, unless those mills are specialty grade 
sulfite mills;
    (3) The specialty grade sulfite pulp segment consists of those 
papergrade sulfite mills where a significant portion of production is 
characterized by pulp with a high percentage of alpha cellulose and high 
brightness sufficent to produce end products such as plastic molding 
compounds, saturating and laminating products, and photographic papers. 
The specialty grade segment also includes those mills where a major 
portion of production is 91 ISO brightness and above.



Sec. 430.52  Effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology 
          currently available (BPT).

Sec. 430.75  New source performance standards (NSPS).

    (a) The following applies to mechanical pulp facilities where pulp 
and paper at groundwood mills are produced through the application of 
the thermo-mechanical process; mechanical pulp facilities where the 
integrated production of pulp and coarse paper, molded pulp products, 
and newsprint at groundwood mills occurs; and mechanical pulp facilities 
where the integrated production of pulp and fine paper at groundwood 
mills occurs: any new source subject to this subpart must achieve the 
following new source performance standards (NSPS), except that non-
continuous dischargers shall not be subject to the maximum day and 
average of 30 consecutive days effluent limitations for BOD5 and TSS, 
but shall be subject to annual average effluent limitations. Also, for 
non-continuous dischargers, concentration limitations (mg/l) shall 
apply, where provided. Concentration limitations will only apply to non-
continuous dischargers. Pentachlorophenol and trichlorophenol 
limitations are only applicable at facilities where chlorophenolic-
containing biocides are used. Permittees not using chlorophenolic-
containing biocides must certify to the permit-issuing authority that 
they are not using these biocides. Zinc limitations are only applicable 
at facilities where zinc hydrosulfite is used as a bleaching agent. 
Permittees not using zinc hydrosulfite as a bleaching agent must certify 
to the permit issuing authority that they are not using this bleaching 
compound:

Sec. 430.103  Effluent limitations guidelines representing the degree of effluent reduction
attainable by the application of the best conventional pollutant 
          control technology (BCT).

    (a) Except as provided in 40 CFR 125.30 through 125.32, any existing 
point source subject to this subpart shall achieve the following 
effluent limitations representing the degree of effluent reduction 
attainable by the application of the best conventional pollutant control 
technology (BCT): The limitations shall be the same as those specified 
for conventional pollutants (which are defined in 40 CFR 401.16) in 
Sec. 430.102 of this subpart for the best practicable control 
technology currently available (BPT).
    (b) For secondary fiber non-deink facilities where paperboard from 
wastepaper is produced, non-continuous dischargers shall not be subject 
to the maximum day and average-of-30-consecutive-days limitations, but 
shall be subject to annual average effluent limitations determined by 
dividing the average-of-30-consecutive-days limitations for BOD5 and TSS 
by 1.77 and 2.18.
    (c) For secondary fiber non-deink facilities where builders' paper 
and roofing felt from wastepaper are produced, non-continuous 
dischargers shall not be subject to the maximum day and average-of-30-
consecutive-days limitations, but shall be subject to annual average 
effluent limitations determined by dividing the average-of-30-
consecutive-days limitations for BOD5 and TSS by 1.90 and 1.90.



Sec. 430.104  Effluent limitations representing the degree of effluent reduction attainable 
by the application of the best available technology economically 
          achievable (BAT).

    Except as provided in 40 CFR 125.30 through 125.32, any existing 
point source subject to this subpart where chlorophenolic-containing 
biocides are used must achieve the following effluent limitations 
representing the degree of effluent reduction attainable by the

application of the best available technology economically achievable 
(BAT). Non-continuous dischargers shall not be subject to the maximum 
day mass limitations in kg/kkg (lb/1000 lb) but shall be subject to 
concentration limitations. Concentration limitations are only applicable 
to non-continuous dischargers. Permittees not using chlorophenolic-
containing biocides must certify to the permit-issuing authority that 
they are not using these biocides:
