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 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

[[Page 9]]

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 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.

                                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:

    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

[[Page 21]]

there is no reappearance of the pink color after 30 seconds.

                             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.

         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.

ability to generate acceptable accuracy and precision by performing the 
following operations.
    (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.\1\

                          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

[[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.

Sec. 426.116  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.

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

[[Page 45]]

in a publicly owned treatment works, whereas mineral oil may not be 
readily removed and may pass through untreated, two separate limitations 
are established.

                           General Provisions



Sec. 429.10  Applicability.

    This part applies to any timber products processing operation, and 
any plant producing insulation board with wood as the major raw 
material, 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. 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 noncontact 
cooling water, material storage yard runoff (either raw material or 
processed wood storage), and boiler blowdown. 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.

                           General Provisions



Sec. 430.00  Applicability.

    This part applies to any pulp, paper, or paperboard mill 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. 430.01  General definitions.

    In addition to the definitions set forth in 40 CFR part 401, the 
following definitions apply to this part:
    (a) 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 subparts A, B, D, and E 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.
    (b) 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.
    (c) 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 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.

Sec. 430.10  Applicability; description of the unbleached kraft subcategory.

    The provisions of this subpart are applicable to discharges 
resulting from the production of pulp and paper at unbleached kraft 
mills.



Sec. 430.11  Specialized definitions.

    For the purpose of this subpart, the general definitions, 
abbreviations, and methods of analysis set forth in 40 CFR part 401 and 
Sec. 430.01 shall apply to this subpart.



Sec. 430.12  Effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology 
          currently available (BPT).

    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. 430.55  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 determined by dividing 
the average of 30 consecutive days limitations for BOD5 by 1.91 and TSS 
by 1.90. 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. 430.72  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), except that noncontinuous discharges 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 by 1.78 and TSS by 1.82.

Sec. 430.95  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 determined by dividing 
the average of 30 consecutive days limitations for BOD5 by 1.91 and TSS 
by 1.90. 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 these biocides.

Sec. 430.115  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 determined by dividing 
the average of 30 consecutive days limitations for BOD5 by 1.91 and TSS 
by 1.90. 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 
chlorophenic-containing biocides must certify to the permit-issuing 
authority that they are not using these biocides.

Sec. 430.210  Applicability; description of the papergrade sulfite (drum wash) subcategory.

    The provisions of this subpart are applicable to discharge resulting 
from the integrated production of pulp and paper at papergrade sulfite 
mills, where vacuum or pressure drums are used to wash pulp.



Sec. 430.211  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, 
abbreviations, and methods of analysis set forth in 40 CFR part 401 and 
Sec. 430.01 shall apply to this subpart.
    (b) Sulfite cooking liquor shall be 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.

Sec. 430.212  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), except that noncontinuous 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 by 1.78 and TSS by 1.82.

Sec. 430.245  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 determined by dividing 
the average of 30 consecutive days limitations for BOD5 by 1.48 and TSS 
by 1.64. 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. 431.10  Applicability; description of the builders' paper and roofing felt subcategory.

    The provisions of this subpart are applicable to discharges 
resulting from the production of builders' paper and roofing felt from 
wastepaper.



Sec. 431.11  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, 
abbreviations, and methods of analysis set forth in 40 CFR

[[Page 185]]

part 401 and Sec. 430.01 shall apply to this subpart.
    (b) 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. Production shall be 
measured at the off-the-machine moisture content. Production shall be 
determined for each mill based upon past production practices, present 
trends, or committed growth.
    (c) 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 by this subpart 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 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 this subpart.



Sec. 431.12  Effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology 
          currently available (BPT).

    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

              Subpart A--Simple Slaughterhouse Subcategory



Sec. 432.10   Applicability; description of the simple slaughterhouse subcategory.

    The provisions of this subpart are applicable to discharges 
resulting from the production of red meat carcasses, in whole or part, 
by simple slaughterhouses.



Sec. 432.11   Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, abbreviations 
and methods of analysis set forth in 40 CFR part 401 shall apply to this 
subpart.
    (b) The term ``slaughterhouse'' shall mean a plant that slaughters 
animals and has as its main product fresh meat as whole, half or quarter 
carcasses or smaller meat cuts.
    (c) The term ``simple slaughterhouse'' shall mean a slaughterhouse 
which accomplishes very limited by-product processing, if any, usually 
no more than two of such operations as rendering, paunch and viscera 
handling, blood processing, hide processing, or hair processing.
    (d) The term ``LWK'' (live weight killed) shall mean the total 
weight of the total number of animals slaughtered during the time to 
which the effluent limitations apply; i.e., during any one day or any 
period of thirty consecutive days.
    (e) The term ``ELWK'' (equivalent live weight killed) shall mean the 
total weight of the total number of animals slaughtered at locations 
other than the slaughterhouse or packinghouse, which animals provide 
hides, blood, viscera or renderable materials for processing at that 
slaughterhouse, in addition to those derived from animals slaughtered on 
site.
    (f) The term ``oil and grease'' shall mean those components of 
process waste water amenable to measurement by the method described in 
``Methods for Chemical Analysis of Water and Wastes,'' 1971, EPA, 
Analytical Quality Control Laboratory, page 217.

Sec. 432.12   Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best practicable control 
          technology currently available.

    Except as provided in Secs. 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 practicable control technology 
currently available (BPT):
    (a) The following limitations establish the quantity or quality of 
pollutants or pollutant properties, controlled by this section and 
attributable to on-site slaughter or subsequent meat, meat product or 
by-product processing of carcasses of animals slaughtered on-site, which 
may be discharged by a point source subject to the provisions of this 
subpart after application of the best practicable control technology 
currently available:

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, abbreviations 
and methods of analysis set forth in 40 CFR part 401 shall apply to this 
subpart.
    (b) The term ``slaughterhouse'' shall mean a plant that slaughters 
animals and has as its main product fresh meat as whole, half or quarter 
carcasses or smaller meat cuts.
    (c) The term ``complex slaughterhouse'' shall mean a slaughterhouse 
that accomplishes extensive by-product processing, usually at least 
three of such operations as rendering, paunch and viscera handling, 
blood processing, hide processing, or hair processing.
    (d) The term ``LWK'' (live weight killed) shall mean the total 
weight of the total number of animals slaughtered during the time to 
which the effluent limitations apply; i.e., during any one day or any 
period of thirty consecutive days.
    (e) The term ``ELWK'' (equivalent live weight killed) shall mean the 
total weight of the total number of animals slaughtered at locations 
other than the slaughterhouse or packinghouse, which animals provide 
hides, blood, viscera or renderable materials for processing at that 
slaughterhouse, in addition to those derived from animals slaughtered on 
site.
    (f) The term ``oil and grease'' shall mean those components of 
process waste water amenable to measurement by the method described in 
``Methods for Chemical Analysis of Water and Wastes,'' 1971, EPA,

           Subpart C--Low-Processing Packinghouse Subcategory



Sec. 432.30   Applicability; description of the low-processing packinghouse subcategory.

    The provisions of this subpart are applicable to discharges 
resulting from the production of red meat carcasses in whole or part, by 
low-processing packinghouses.



Sec. 432.31   Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, abbreviations 
and methods of analysis set forth in 40 CFR part 401 shall apply to this 
subpart.
    (b) The term ``packinghouse'' shall mean a plant that both 
slaughters animals and subsequently processes carcasses into cured, 
smoked, canned or other prepared meat products.
    (c) The term ``low processing packinghouse'' shall mean a 
packinghouse that processes no more than the total animals killed at 
that plant, normally processing less than the total kill.
    (d) The term ``LWK'' (live weight killed) shall mean the total 
weight of the total number of animals slaughtered during the time to 
which the effluent limitations apply; i.e., during any one day or any 
period of thirty consecutive days.
    (e) The term ``ELWK'' (equivalent live weight killed) shall mean the 
total weight of the total number of animals slaughtered at locations 
other than the slaughterhouse or packinghouse, which animals provide 
hides, blood, viscera or renderable materials for processing at that 
slaughterhouse, in addition to those derived from animals slaughtered 
on-site.
    (f) The term ``oil and grease'' shall mean those components of 
process waste water amenable to measurement by the method described in 
``Methods for Chemical Analysis of Water and Wastes,'' 1971, EPA, 
Analytical Quality Control Laboratory, page 217.



Sec. 432.32   Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best practicable control 
          technology currently available.

    Except as provided in Secs. 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 practicable control technology 
currently available (BPT):
    (a) The following limitations establish the quantity or quality of 
pollutants or pollutant properties, controlled by this section and 
attributable to on-site slaughter or subsequent meat, meat product or 
byproduct, processing of carcasses of animals slaughtered on-site, which 
may be discharged by a point source subject to the provisions of this 
subpart after application of the best practicable control technology 
currently available:

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, abbreviations 
and methods of analysis set forth in 40 CFR part 401 shall apply to this 
subpart.
    (b) The term ``packinghouse'' shall mean a plant that both 
slaughters animals and subsequently processes carcasses into cured, 
smoked, canned or other prepared meat products.
    (c) The term ``high-processing packinghouse'' shall mean a 
packinghouse which processes both animals slaughtered at the site and 
additional carcasses from outside sources.
    (d) The term ``LWK'' (live weight killed) shall mean the total 
weight of the total number of animals slaughtered during the time to 
which the effluent limitations apply; i.e., during any one day or any 
period of thirty consecutive days.
    (e) The term ``ELWK'' (equipment live weight killed) shall mean the 
total

[[Page 200]]

weight of the total number of animals slaughtered at locations other 
than the slaughterhouse or packinghouse, which animals provide hides, 
blood, viscera or renderable materials for processing at that 
slaughterhouse, in addition to those derived from animals slaughtered 
on-site.
    (f) The term ``oil and grease'' shall mean those components of 
process waste water amenable to measurement by the method described in 
``Methods for Chemical Analysis of Water and Wastes,'' 1971, EPA,

Sec. 433.12  Monitoring requirements.

    (a) In lieu of requiring monitoring for TTO, the permitting 
authority (or, in the case of indirect dischargers, the control 
authority) may allow dischargers to make the following certification 
statement: ``Based on my inquiry of the person or persons directly 
responsible for managing compliance with the permit limitation [or 
pretreatment standard] for total toxic organics (TTO), I certify that, 
to the best of my knowledge and belief, no dumping of concentrated toxic 
organics into the wastewaters has occurred since filing of the last 
discharge monitoring report. I further certify that this facility is 
implementing the toxic organic management plan submitted to the 
permitting [or control] authority.'' For direct dischargers, this 
statement is to be included as a ``comment'' on the Discharge Monitoring 
Report required by 40 CFR 122.44(i), formerly 40 CFR 122.62(i). For 
indirect dischargers, the statement is to be included as a comment to 
the periodic reports required by 40 CFR 403.12(e). If monitoring is 
necessary to measure compliance with the TTO standard, the industrial 
discharger need analyse for only those pollutants which would reasonably 
be expected to be present.
    (b) In requesting the certification alternative, a discharger shall 
submit a solvent management plan that specifies to the satisfaction of 
the permitting authority (or, in the case of indirect dischargers, the 
control authority) the toxic organic compounds used; the method of 
disposal used instead of dumping, such as reclamation, contract hauling, 
or incineration; and procedures for ensuring that toxic organics do not 
routinely spill or leak into the wastewater. For direct dischargers, the 
permitting authority shall incorporate the plan as a provision of the 
permit.
    (c) Self-monitoring for cyanide must be conducted after cyanide 
treatment and before dilution with other streams. Alternatively, samples 
may be taken of the final effluent, if the plant limitations are 
adjusted based on the dilution ratio of the cyanide waste stream flow to 
the effluent flow.

    (a) The term ``acid or ferruginous mine drainage'' means mine 
drainage which, before any treatment, either has a pH of less than 6.0 
or a total iron concentration equal to or greater than 10 mg/l.
    (b) The term ``active mining area'' means the area, on and beneath 
land, used or disturbed in activity related to the extraction, removal, 
or recovery of coal from its natural deposits. This term excludes coal 
preparation plants, coal preparation plant associated areas and post-

bond based upon its determination that reclamation work (including, in 
the case of underground mines, mine sealing and abandonment procedures) 
has been satisfactorily completed.
    (e) The term ``coal preparation plant'' means a facility where coal 
is subjected to cleaning, concentrating, or other processing or

being re-mined.
    (i) The construction of which is commenced after May 4, 1984; or
    (ii) Which is determined by the EPA Regional Administrator to 
constitute a ``major alteration''. In making this determination, the 
Regional Administrator shall take into account whether one or more of 
the following events resulting in a new, altered or increased discharge 
of pollutants has occurred after May 4, 1984 in connection with the mine 
for which the NPDES permit is being considered:

    (E) Such other factors as the Regional Administrator deems relevant.
    (2) No provision in this part shall be deemed to affect the 
classification as a new source of a facility which was classified as a 
new source coal mine under previous EPA regulations, but would not be 
classified as a new source under this section, as modified. Nor shall 
any provision in this part be deemed to affect the standards applicable 
to such facilities, except as provided in Sec.  434.65 of this chapter.
    (k) The term ``post-mining area'' means:

recurrence interval of once in one, two, and ten years respectively as 
defined by the National Weather Service and Technical Paper No. 40, 
``Rainfall Frequency Altas of the U.S.,'' May 1961, or equivalent 
regional or rainfall probability information developed therefrom.
    (o) The terms ``treatment facility'' and ``treatment system'' mean 
all structures which contain, convey, and as necessay, chemically or 
physically treat coal rine drainage, coal preparation plant process 
wastewater, or drainage from coal preparation plant associated areas,

[[Page 228]]

Imhoff cone to the one-liter mark with a thoroughly mixed sample. Allow 
to settle undisturbed for 45 minutes. Gently stir along the inside 
surface of the cone with a stirring rod. Allow to settle undisturbed for 
15 minutes longer. Record the volume of settled material in the cone as 
milliliters per liter. Where a separation of settleable and floating 
materials occurs, do not include the floating material in the reading. 
Notwithstanding any provision of 40 CFR part 136, the method detection 
limit for measuring settleable solids under this part shall be 0.4 ml/l.



Sec. 434.65  Modification of NPDES permits for new sources.

    Any coal mine or coal preparation plant which was considered a new 
source under previous EPA regulations may, notwithstanding Sec. 122.62

Sec. 435.10  Applicability; description of the offshore subcategory.

    The provisions of this subpart are applicable to those facilities 
engaged in field exploration, drilling, well production, and well 
treatment in the oil and gas extraction industry which are located in 
waters that are seaward of the inner boundary of the territorial seas 
(``offshore'') as defined in section 502(g) of the Clean Water Act. 
Offshore facilities that transport wastes to onshore or coastal 
locations for treatment and disposal offshore are subject to the 
regulations that are applicable to the location of where the wastes are 
generated or the wellhead. Wastes transported from one subcategory for 
subsequent discharge in another subcategory of the oil and gas 
extraction point source category may only be disposed of pursuant to a 
valid NPDES permit.



Sec. 435.11  Specialized definitions.

concentration allowed as measured in any single sample of the barite.
    (l) The term maximum for any one day as applied to BPT, BCT and BAT 
effluent limitations and NSPS for oil and grease in produced water shall 
mean the maximum concentration allowed as measured by the average of 
four grab samples collected over a 24-hour period that are analyzed 
separately. Alternatively, for BAT and NSPS the maximum concentration 
allowed may be determined on the basis of physical composition of the 
four grab samples prior to a single analysis.
    (m) The term minimum as applied to BAT effluent limitations and NSPS 
for drilling fluids and drill cuttings shall mean the minimum 96-hour 
LC50 value allowed as measured in any single sample of the discharged 
waste stream. The term minimum as applied to BPT and BCT effluent 
limitations and NSPS for sanitary wastes shall mean the minimum 
concentration value allowed as measured in any single sample of the 
discharged waste stream.

existing NPDES permit immediately prior to the effective date of these 
guidelines pending EPA issuance of a new source NPDES permit.
    (q) The term no discharge of free oil shall mean that waste streams 
may not be discharged when they would cause a film or sheen upon or a 
discoloration of the surface of the receiving water or fail the static 
sheen test defined in appendix 1 to 40 CFR part 435, subpart A.

         Appendix 1 to Subpart A of Part 435--Static Sheen Test

                        1. Scope and Application

    This method is to be used as a compliance test for the ``no 
discharge of free oil'' requirement for discharges of drilling fluids, 
drill cuttings, produced sand, and well treatment, completion and 
workover fluids. ``Free oil'' refers to any oil contained in a waste 
stream that when discharged will cause a film or sheen upon or a 
discoloration of the surface of the receiving water.

                          2. Summary of Method

    15-mL samples of drilling fluids or well treatment, completion, and 
workover fluids, and 15-g samples (wet weight basis) of drill cuttings 
or produced sand are introduced into ambient seawater in a container 
having an air-to-liquid interface area of 1000 cm2 (155.5 
in2). Samples are dispersed within the container and observations 
made no more than one hour later to ascertain if these materials cause a 
sheen, iridescence, gloss, or increased reflectance on the surface of 
the test seawater. The occurrence of any of these visual observations 
will constitute a demonstration that the tested material contains ``free 
oil,'' and therefore results in a prohibition of its discharge into 
receiving waters.

                            3. Interferences

    Residual ``free oil'' adhering to sampling containers, the magnetic 
stirring bar used to mix the sample, and the stainless steel spatula 
used to mix the sample will be the principal sources of contamination 
problems. These problems should only occur if improperly washed and 
cleaned equipment are used for the test. The use of disposable equipment 
minimizes the potential for similar contamination from pipettes and the 
test container.

                  4. Apparatus, Materials, and Reagents

    4.1 Apparatus
    4.1.1  Sampling Containers: 1-liter polyethylene beakers and 1-liter 
glass beakers.
    4.1.2  Graduated cylinder: 100-mL graduated cylinder required only 
for operations where predilution of mud discharges is required.
    4.1.3  Plastic disposable weighing boats.

    None currently specified.

                      6. Quality Control Procedures

    None currently specified.

                    7. Sample Collection and Handling

    7.1  Sampling containers must be thoroughly washed with detergent, 
rinsed a minimum of three times with fresh water, and allowed to air dry 
before samples are collected.
    7.2  Samples of drilling fluid to be tested shall be taken at the 
shale shaker after cuttings have been removed. The sample volume should 
range between 200 mL and 500 mL.
    7.3  Samples of drill cuttings will be taken from the shale shaker 
screens with a clean spatula or similar instrument and placed in a glass 
beaker. Cuttings samples shall be collected prior to the addition of any 
washdown water and should range between 200 g and 500 g.
    7.4  Samples of produced sand must be obtained from the solids 
control equipment from which the discharge occurs on any given day and 
shall be collected prior to the addition of any washdown water; samples 
should range between 200 g and 500 g.
    7.5  Samples of well treatment, completion, and workover fluids must 
be obtained from the holding facility prior to discharge; the sample 
volume should range between 200 mL and 500 mL.
    7.6  Samples must be tested no later than 1 hour after collection.
    7.7  Drilling fluid samples must be mixed in their sampling 
containers for 5 minutes prior to the test using a magnetic bar stirrer. 
If predilution is imposed as a permit condition, the sample must be 
mixed at the same ratio with the same prediluting water as the 
discharged muds and stirred for 5 minutes.
    7.8  Drill cuttings must be stirred and well mixed by hand in their 
sampling containers prior to testing, using a stainless steel spatula.

                              8. Procedure

    8.1  Ambient receiving water must be used as the ``receiving water'' 
in the test. The temperature of the test water shall be as close as 
practicable to the ambient conditions in the receiving water, not the 
room temperature of the observation facility. The test container must 
have an air-to-liquid interface area of 1000 50 cm2. 
The surface of the water should be no more than 1.27 cm (.5 inch) below 
the top of the test container.
    8.2  Plastic liners shall be used, one per test container, and 
discarded afterwards. Some liners may inhibit spreading of added oil; 
operators shall determine an appropriate local source of liners that do 
not inhibit the spreading of the oil film.
    8.3  A 15-mL sample of drilling fluid or well treatment, completion, 
and workover fluids must be introduced by pipette into the test 
container 1 cm below the water surface. Pipettes must be filled and 
discharged with test material prior to the transfer of test material and 
its introduction into test containers. The test water/test material 
mixture must be stirred using the pipette to distribute the test 
material homogeneously throughout the test water. The pipette must be 
used only once for a test and then discarded.
    8.4  Drill cuttings or produced sand should be weighed on plastic 
weighing boats; 15-g samples must be transferred by scraping test 
material into the test water with a stainless steel spatula. Drill 
cuttings shall not be prediluted prior to testing. Also, drilling fluids 
and cuttings will be tested separately. The weighing boat must be 
immersed in the test water and scraped with the spatula to transfer any 
residual material to the test container. The drill cuttings or produced 
sand must be stirred with the spatula to an even distribution of solids 
on the bottom of the test container.
    8.5  Observations must be made no later than 1 hour after the test 
material is transferred to the test container. Viewing points above the 
test container should be made from at least three sides of the test 
container, at viewing angles of approximately 60 deg. and 30 deg. from 
the horizontal. Illumination of the test container must be 
representative of adequate lighting for a working environment to conduct 
routine laboratory procedures. It is recommended that the water surface 
of the test container be observed under a fluorescent light source such 
as a dissecting microscope light. The light source shall be positioned 
above and directed over the entire surface of the pan.
    8.6  Detection of a ``silvery'' or ``metallic'' sheen or gloss, 
increased reflectivity, visual color, iridescence, or an oil slick on 
the water surface of the test container surface shall constitute a 
demonstration of ``free oil.'' These visual observations include 
patches, streaks, or sheets of such altered surface characteristics. If 
the free oil content of the sample approaches or exceeds 10%, the water 
surface of the test container may lack color, a sheen, or iridescence, 
due to the increased thickness of the film; thus, the observation for an 
oil slick is required. The surface of the test container shall not be 
disturbed in any manner that reduces the size of any sheen or slick that 
may be present.
    If an oil sheen or slick occurs on less than one-half of the surface 
area after the sample is introduced to the test container, observations 
will continue for up to 1 hour. If the sheen or slick increases in size 
and covers greater than one-half of the surface area of

[[Page 236]]

the test container during the observation period, the discharge of the 
material shall cease. If the sheen or slick does not increase in size to 
cover greater than one-half of the test container surface area after one 
hour of observation, discharge may continue and additional sampling is 
not required.
    If a sheen or slick occurs on greater than one-half of the surface 
area of the test container after the test material is introduced, 
discharge of the tested material shall cease. The permittee may retest 
the material causing the sheen or slick. If subsequent tests do not 
result in a sheen or slick covering greater than one-half of the surface 
area of the test container, discharge may continue.

   Appendix 2 to Subpart A of Part 435--Drilling Fluids Toxicity Test

                          I. Sample Collection

    The collection and preservation methods for drilling fluids (muds) 
and water samples presented here are designed to minimize sample 
contamination and alteration of the physical or chemical properties of 
the samples due to freezing, air oxidation, or drying.

                              I-A Apparatus

    (1) The following items are required for water and drilling mud 
sampling and storage:
    a. Acid-rinsed linear-polyethylene bottles or other appropriate 
noncontaminating drilling mud sampler.
    b. Acid-rinsed linear-polyethylene bottles or other appropriate 
noncontaminating water sampler.
    c. Acid-rinsed linear-polyethylene bottles or other appropriate 
noncontaminated vessels for water and mud samples.
    d. Ice chests for preservation and shipping of mud and water 
samples.

                           I-B. Water Sampling

    (1) Collection of water samples shall be made with appropriate acid-
rinsed linear-polyethylene bottles or other appropriate non-
contaminating water sampling devices. Special care shall be taken to 
avoid the introduction of contaminants from the sampling devices and 
containers. Prior to use, the sampling devices and containers should be 
thoroughly cleaned with a detergent solution, rinsed with tap water, 
soaked in 10 percent hydrochloric acid (HCl) for 4 hours, and then 
thoroughly rinsed with glass-distilled water.

                       I-C. Drilling Mud Sampling

    (1) Drilling mud formulations to be tested shall be collected from 
active field systems. Obtain a well-mixed sample from beneath the shale 
shaker after the mud has passed through the screens. Samples shall be 
stored in polyethylene containers or in other appropriate uncontaminated 
vessels. Prior to sealing the sample containers on the platform, flush 
as much air out of the container by filling it with drilling fluid 
sample, leaving a one inch space at the top.
    (2) Mud samples shall be immediately shipped to the testing facility 
on blue or wet ice (do not use dry ice) and continuously maintained at 
0-4 deg. C until the time of testing.
    (3) Bulk mud samples shall be thoroughly mixed in the laboratory 
using a 1000 rpm high shear mixer and then subdivided into individual, 
small wide-mouthed (e.g., one or two liter) non-contaminating containers 
for storage.
    (4) The drilling muds stored in the laboratory shall have any excess 
air removed by flushing the storage containers with nitrogen under 
pressure anytime the containers are opened. Moreover, the sample in any 
container opened for testing must be thoroughly stirred using a 1000 rpm 
high shear mixer prior to use.
    (5) Most drilling mud samples may be stored for periods of time 
longer than 2 weeks prior to toxicity testing provided that proper 
containers are used and proper condition are maintained.

           II. Suspended Particulate Phase Sample Preparation

    (1) Mud samples that have been stored under specified conditions in 
this protocol shall be prepared for tests within three months after 
collection. The SPP shall be prepared as detailed below.

                             II--A Apparatus

    (1) The following items are required:
    a. Magnetic stir plates and bars.
    b. Several graduated cylinders, ranging in volume from 10 mL to 1 L
    c. Large (15 cm) powder funnels.
    d. Several 2-liter graduated cylinders.
    e. Several 2-liter large mouth graduated Erlenmeyer flasks.
    (2) Prior to use, all glassware shall be thoroughly cleaned. Wash 
all glassware with detergent, rinse five times with tap water, rinse 
once with acetone, rinse several times with distilled or deionized 
water, place in a clean 10-percent (or stronger) HCl acid bath for a 
minimum of 4 hours, rinse five times with tap water, and then rinse five 
times with distilled or deionized water. For test samples containing 
mineral oil or diesel oil, glassware should be washed with petroleum 
ether to assure removal of all residual oil.
    Note: If the glassware with nytex cups soaks in the acid solution 
longer than 24 hours, then an equally long deionized water soak should 
be performed.

[[Page 237]]

                  II-B Test Seawater Sample Preparation

    (1) Diluent seawater and exposure seawater samples are prepared by 
filtration through a 1.0 micrometer filter prior to analysis.
    (2) Artificial seawater may be used as long as the seawater has been 
prepared by standard methods or ASTM methods, has been properly 
``seasoned,'' filtered, and has been diluted with distilled water to the 
same specified 202 ppt salinity and 202 deg. C 
temperature as the ``natural'' seawater.

                         II-C Sample Preparation

    (1) The pH of the mud shall be tested prior to its use. If the pH is 
less than 9, if black spots have appeared on the walls of the sample 
container, or if the mud sample has a foul odor, that sample shall be 
discarded. Subsample a manageable aliquot of mud from the well-mixed 
original sample. Mix the mud and filtered test seawater in a volumetric 
mud-to-water ratio of 1 to 9. This is best done by the method of 
volumetric displacement in a 2-L, large mouth, graduated Erlenmeyer 
flask. Place 1000 mL of seawater into the graduated Erlenmeyer flask. 
The mud subsample is then carefully added via a powder funnel to obtain 
a total volume of 1200 mL. (A 200 mL volume of the mud will now be in 
the flask).
    The 2-L, large mouth, graduated Erlenmeyer flask is then filled to 
the 2000 mL mark with 800 mL of seawater, which produces a slurry with a 
final ratio of one volume drilling mud to nine volumes water. If the 
volume of SPP required for testing or analysis exceeds 1500 to 1600 mL, 
the initial volumes should be proportionately increased. Alternatively, 
several 2-L drill mud/water slurries may be prepared as outlined above 
and combined to provide sufficient SPP.
    (2) Mix this mud/water slurry with magnetic stirrers for 5 minutes. 
Measure the pH and, if necessary, adjust (decrease) the pH of the slurry 
to within 0.2 units of the seawater by adding 6N HCl while stirring the 
slurry. Then, allow the slurry to settle for 1 hour. Record the amount 
of HCl added.
    (3) At the end of the settling period, carefully decant (do not 
siphon) the Suspended Particulate Phase (SPP) into an appropriate 
container. Decanting the SPP is one continuous action. In some cases no 
clear interface will be present; that is, there will be no solid phase 
that has settled to the bottom. For those samples the entire SPP 
solution should be used when preparing test concentrations. However, in 
those cases when no clear interface is present, the sample must be 
remixed for five minutes. This insures the homogeneity of the mixture 
prior to the preparation of the test concentrations. In other cases, 
there will be samples with two or more phases, including a solid phase. 
For those samples, carefully and continuously decant the supernatant 
until the solid phase on the bottom of the flask is reached. The 
decanted solution is defined to be 100 percent SPP. Any other 
concentration of SPP refers to a percentage of SPP that is obtained by 
volumetrically mixing 100 percent SPP with seawater.
    (4) SPP samples to be used in toxicity tests shall be mixed for 5 
minutes and must not be preserved or stored.
    (5) Measure the filterable and unfilterable residue of each SPP 
prepared for testing. Measure the dissolved oxygen (DO) and pH of the 
SPP. If the DO is less than 4.9 ppm, aerate the SPP to at least 4.9 ppm 
which is 65 percent of saturation. Maximum allowable aeration time is 5 
minutes using a generic commercial air pump and air stone. Neutralize 
the pH of the SPP to a pH 7.8.1 using a dilute HCl solution. 
If too much acid is added to lower the pH saturated NaOH may be used to 
raise the pH to 7.8.1 units. Record the amount of acid or 
NaOH needed to lower/raise to the appropriate pH. Three repeated DO and 
pH measurements are needed to insure homogeneity and stability of the 
SPP. Preparation of test concentrations may begin after this step is 
complete.
    (6) Add the appropriate volume of 100 percent SPP to the appropriate 
volume of seawater to obtain the desired SPP concentration. The control 
is seawater only. Mix all concentrations and the control for 5 minutes 
by using magnetic stirrers. Record the time; and, measure DO and pH for 
Day 0. Then, the animals shall be randomly selected and placed in the 
dishes in order to begin the 96-hour toxicity test.

III. Guidance for Performing Suspended Particulate Phase Toxicity Tests 
                         Using Mysidopsis bahia

                             III-A Apparatus

    (1) Items listed by Borthwick [1] are required for each test series, 
which consists of one set of control and test containers, with three 
replicates of each.

                  III-B Sample Collection Preservation

    (1) Drilling muds and water samples are collected and stored, and 
the suspended particulate phase prepared as described in section 1-C.

                         III-C Species Selection

    (1) The Suspended Particulate Phase (SPP) tests on drilling muds 
shall utilize the test species Mysidopsis bahia. Test animals shall be 3 
to 6 days old on the first day of exposure. Whatever the source of the 
animals, collection and handling should be as gentle as possible. 
Transportation to the laboratory

[[Page 238]]

should be in well-aerated water from the animal culture site at the 
temperature and salinity from which they were cultured. Methods for 
handling, acclimating, and sizing bioassay organisms given by Borthwick 
[1] and Nimmo [2] shall be followed in matters for which no guidance is 
given here.

                      III-D Experimental Conditions

    (1) Suspended particulate phase (SPP) tests should be conducted at a 
salinity of 202 ppt. Experimental temperature should be 
202 deg.C. Dissolved oxygen in the SPP shall be raised to or 
maintained above 65 percent of saturation prior to preparation of the 
test concentrations. Under these conditions of temperature and salinity, 
65 percent saturation is a DO of 5.3 ppm. Beginning at Day 0-before the 
animals are placed in the test containers DO, temperature, salinity, and 
pH shall be measured every 24 hours. DO should be reported in milligrams 
per liter.
    (2) Aeration of test media is required during the entire test with a 
rate estimated to be 50-140 cubic centimeters/minute. This air flow to 
each test dish may be achieved through polyethylene tubing (0.045-inch 
inner diameter and 0.062-inch outer diameter) by a small generic 
aquarium pump. The delivery method, surface area of the aeration stone, 
and flow characteristics shall be documented. All treatments, including 
control, shall be the same.
    (3) Light intensity shall be 1200 microwatts/cm \2\ using cool white 
fluorescent bulbs with a 14-hr light and 10-hr dark cycle. This light/
dark cycle shall also be maintained during the acclimation period and 
the test.

                      III-E Experimental Procedure

    (1) Wash all glassware with detergent, rinse five times with tap 
water, rinse once with acetone, rinse several times with distilled or 
deionized water, place in a clean 10 percent HCl acid bath for a minimum 
of 4 hours, rinse five times with tap water, and then rinse five times 
with distilled water.
    (2) Establish the definitive test concentration based on results of 
a range finding test. A minimum of five test concentrations plus a 
negative and positive (reference toxicant) control is required for the 
definitive test. To estimate the LC-50, two concentrations shall be 
chosen that give (other than zero and 100 percent) mortality above and 
below 50 percent.
    (3) Twenty organisms are exposed in each test dish. Nytex 
cups shall be inserted into every test dish prior to adding the animals. 
These ``nylon mesh screen'' nytex holding cups are fabricated by gluing 
a collar of 363-micrometer mesh nylon screen to a 15-centimeter wide 
Petri dish with silicone sealant. The nylon screen collar is 
approximately 5 centimeters high. The animals are then placed into the 
test concentration within the confines of the Nytex cups.
    (4) Individual organisms shall be randomly assigned to treatment. A 
randomization procedure is presented in section V of this protocol. Make 
every attempt to expose animals of approximately equal size. The 
technique described by Borthwick [1], or other suitable substitutes, 
should be used for transferring specimens. Throughout the test period, 
mysids shall be fed daily with approximately 50 Artemia (brine shrimp) 
nauplii per mysid. This will reduce stress and decrease cannibalism.
    (5) Cover the dishes, aerate, and incubate the test containers in an 
appropriate test chamber. Positioning of the test containers holding 
various concentrations of test solution should be randomized if 
incubator arrangement indicates potential position difference. The test 
medium is not replaced during the 96-hour test.
    (6) Observations may be attempted at 4, 6 and 8 hours; they must be 
attempted at 0, 24, 48, and 72 hours and must be made at 96 hours. 
Attempts at observations refers to placing a test dish on a light table 
and visually counting the animals. Do not lift the ``nylon mesh screen'' 
cup out of the test dish to make the observation. No unnecessary 
handling of the animals should occur during the 96 hour test period. DO 
and pH measurements must also be made at 0, 24, 48, 72, and 96 hours. 
Take and replace the test medium necessary for the DO and pH 
measurements outside of the nytex cups to minimize stresses on the 
animals.
    (7) At the end of 96 hours, all live animals must be counted. Death 
is the end point, so the number of living organisms is recorded. Death 
is determined by lack of spontaneous movement. All crustaceans molt at 
regular intervals, shedding a complete exoskeleton. Care should be taken 
not to count an exoskeleton. Dead animals might decompose or be eaten 
between observations. Therefore, always count living, not dead animals. 
If daily observations are made, remove dead organisms and molted 
exoskeletons with a pipette or forceps. Care must be taken not to 
disturb living organisms and to minimize the amount of liquid withdrawn.

       IV. Methods for Positive Control Tests (Reference Toxicant)

    (1) Sodium lauryl sulfate (dodecyl sodium sulfate) is used as a 
reference toxicant for the positive control. The chemical used should be 
approximately 95 percent pure. The source, lot number, and percent 
purity shall be reported.
    (2) Test methods are those used for the drilling fluid tests, except 
that the test material was prepared by weighing one gram sodium lauryl 
sulfate on an analytical balance,

[[Page 239]]

adding the chemical to a 100-milliliter volumetric flask, and bringing 
the flask to volume with deionized water. After mixing this stock 
solution, the test mixtures are prepared by adding 0.1 milliliter of the 
stock solution for each part per million desired to one liter of 
seawater.
    (3) The mixtures are stirred briefly, water quality is measured, 
animals are added to holding cups, and the test begins. Incubation and 
monitoring procedures are the same as those for the drilling fluids.

                       V. Randomization Procedure

                        V-A Purpose and Procedure

    (1) The purpose of this procedure is to assure that mysids are 
impartially selected and randomly assigned to six test treatments (five 
drilling fluid or reference toxicant concentrations and a control) and 
impartially counted at the end of the 96-hour test. Thus, each test 
setup, as specified in the randomization procedure, consists of 3 
replicates of 20 animals for each of the six treatments, i.e., 360 
animals per test. Figure 1 is a flow diagram that depicts the procedure 
schematically and should be reviewed to understand the over-all 
operation. The following tasks shall be performed in the order listed.
    (2) Mysids are cultured in the laboratory in appropriate units. If 
mysids are purchased, go to Task 3.
    (3) Remove mysids from culture tanks (6, 5, 4, and 3 days before the 
test will begin, i.e. Tuesday, Wednesday, Thursday, and Friday if the 
test will begin on Monday) and place them in suitably large maintenance 
containers so that they can swim about freely and be fed.

    Note: Not every detail (the definition of suitably large containers, 
for example) is provided here. Training and experience in aquatic animal 
culture and testing will be required to successfully complete these 
tests.

[[Page 241]]

    (4) Remove mysids from maintenance containers and place all animals 
in a single container. The intent is to have homogeneous test population 
of mysids of a known age (3-6 days old).
    (5) For each toxicity test, assign two suitable containers (500-
milliliter (mL) beakers are recommended) for mysid separation/
enumeration. Label each container (A1, A2, B1, B2, and C1, C2, for 
example, if two drilling fluid tests and a reference toxicant test are 
to be set up on one day). The purpose of this task is to allow the 
investigator to obtain a close estimate of the number of animals 
available for testing and to prevent unnecessary crowding of the mysids 
while they are being counted and assigned to test containers. Transfer 
the mysids from the large test population container to the labeled 
separation and enumeration containers but do not place more than 200 
mysids in a 500-mL beaker. Be impartial in transferring the mysids; 
place approximately equal numbers of animals (10-15 mysids is 
convenient) in each container in a cyclic manner rather than placing the 
maximum number each container at one time.

    Note: It is important that the animals not be unduly stressed during 
this selection and assignment procedure. Therefore, it will probably be 
necessary to place all animals (except the batch immediately being 
assigned to test containers) in mesh cups with flowing seawater or in 
large volume containers with aeration. The idea is to provide the 
animals with near optimal conditions to avoid additional stress.

    (6) Place the mysids from the two labeled enumeration containers 
assigned to a specific test into one or more suitable containers to be 
used as counting dishes (2-liter Carolina dishes are suggested). Because 
of the time required to separate, count, and assign mysids, two or more 
people may be involved in completing this task. If this is done, two or 
more counting dishes may be used, but the investigator must make sure 
that approximately equal numbers of mysids from each labeled container 
are placed in each counting dish.
    (7) By using a large-bore, smooth-tip glass pipette, select mysids 
from the counting dish(es) and place them in the 36 individually 
numbered distribution containers (10-ml beakers are suggested). The 
mysids are assigned two at a time to the 36 containers by using a 
randomization schedule similar to the one presented below. At the end of 
selection/assignment round 1, each container will contain two mysids; at 
the end of round 2, they will contain four mysids; and so on until each 
contains ten mysids.

    (8) Transfer mysids from the 36 distribution containers to 18 
labeled test containers in random order. A label is assigned to each of 
the three replicates (A, B, C) of the six test concentrations. Count and 
record the 96 hour response in an impartial order.
    (9) Repeat tasks 5-7 for each toxicity test. A new random schedule 
should be followed in Tasks 6 and 7 for each test.

    Note: If a partial toxicity test is conducted, the procedures 
described above are appropriate and should be used to prepare the single 
test concentration and control, along with the reference toxicant test.

                  V-B. Data Analysis and Interpretation

    (1) Complete survival data in all test containers at each 
observation time shall be presented in tabular form. If greater than 10 
percent mortality occurs in the controls, all data shall be discarded 
and the experiment repeated. Unacceptably high control mortality 
indicates the presence of important stresses on the organisms other than 
the material being tested, such as injury or disease, stressful physical 
or chemical conditions in the containers, or improper handling, 
acclimation, or feeding. If 10 percent mortality or less occurs in the 
controls, the data may be evaluated and reported.

[[Page 242]]

    (2) A definitive, full bioassay conducted according to the EPA 
protocol is used to estimate the concentration that is lethal to 50 
percent of the test organisms that do not die naturally. This toxicity 
measure is known as the median lethal concentration, or LC-50. The LC-50 
is adjusted for natural mortality or natural responsiveness. The maximum 
likelihood estimation procedure with the adjustments for natural 
responsiveness as given by D.J. Finney, in Probit Analysis 3rd edition, 
1971, Cambridge University Press, chapter 7, can be used to obtain the 
probit model estimate of the LC-50 and the 95 percent fiducial 
(confidence) limits for the LC-50. These estimates are obtained using 
the logarithmic transform of the concentration. The heterogeneity factor 
(Finney 1971, pages 70-72) is not used. For a test material to pass the 
toxicity test, according to the requirements stated in the offshore oil 
and gas extraction industry BAT effluent limitations and NSPS, the LC-
50, adjusted for natural responsiveness, must be greater than 3 percent 
suspended particulate phase (SPP) concentration by volume unadjusted for 
the 1 to 9 dilution. Other toxicity test models may be used to obtain 
toxicity estimates provided the modeled mathematical expression for the 
lethality rate must increase continuously with concentration. The 
lethality rate is modeled to increase with concentration to reflect an 
assumed increase in toxicity with concentration even though the observed 
lethality may not increase uniformly because of the unpredictable animal 
response fluctuations.
    (3) The range finding test is used to establish a reasonable set of 
test concentrations in order to run the definitive test. However, if the 
lethality rate changes rapidly over a narrow range of concentrations, 
the range finding assay may be too coarse to establish an adequate set 
of test concentrations for a definitive test.
    (4) The EPA Environmental Research Laboratory in Gulf Breeze, 
Florida prepared a Research and Development Report entitled Acute 
Toxicity of Eight Drilling Fluids to Mysid Shrimp (Mysidopsis bahia), 
May 1984 EPA-600/3-84-067. The Gulf Breeze data for drilling fluid 
number 1 are displayed in Table 1 for purposes of an example of the 
probit analysis described above. The SAS Probit Procedure (SAS 
Institute, Statistical Analysis System, Cary, North Carolina, 1982) was 
used to analyze these data. The 96-hour LC50 adjusted for the estimated 
spontaneous mortality rate is 3.3 percent SPP with 95 percent limits of 
3.0 and 3.5 percent SPP with the 1 to 9 dilution. The estimated 
spontaneous mortality rate based on all of the data is 9.6 percent.

     V-C. The Partial Toxicity Test for Evaluation of Test Material

    (1) A partial test conducted according to EPA protocol can be used 
economically to demonstrate that a test material passes the toxicity 
test. The partial test cannot be used to estimate the LC-50 adjusted for 
natural response.
    (2) To conduct a partial test follow the test protocol for 
preparation of the test material and organisms. Prepare the control 
(zero concentration), one test concentration (3 percent suspended 
particulate phase) and the reference toxicant according to the methods 
of the full test. A range finding test is not used for the partial test.
    (3) Sixty test organisms are used for each test concentration. Find 
the number of test organisms killed in the control (zero percent SPP) 
concentration in the column labeled X0 of Table 2. If the number of 
organisms in the control (zero percent SPP) exceeds the table values, 
then the test is unacceptable and must be repeated. If the number of 
organisms killed in the 3 percent test concentration is less than or 
equal to corresponding number in the column labeled X1 then the 
test material passes the partial toxicity test. Otherwise the test 
material fails the toxicity test.
    (4) Data shall be reported as percent suspended particulate phase.

    (b) Any overflow from facilities governed by this subpart shall not 
be subject to the limitations of paragraph (a) of this section if the 
facilities are designed, constructed and maintained to contain or treat 
the volume of waste water which would result from a 10-year 24-hour 
precipitation event.
    (c) In the case of a discharge into receiving waters for which the 
pH, if unaltered by man's activities, is or would be less than 6.0 and 
water quality criteria in water quality standards approved under the Act 
authorize such lower pH, the pH limitations for such discharge may be 
adjusted downward to the pH water quality criterion for the receiving 
waters. In no case shall a pH limitation outside the range 5.0 to 9.0 be 
permitted.

                           General Provisions



Sec. 439.0  Applicability.

    This part applies to any pharmaceutical manufacturing 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.

[48 FR 49821, Oct. 27, 1983; 48 FR 50322, Nov. 1, 1983]



Sec. 439.1  General definitions.

    In addition to the definitions set forth in 40 CFR part 401, the 
following definitions apply to this part:

[[Page 262]]

    (a) The term ``maximum 30-day average'' shall mean the maximum 
average of daily values for 30 consecutive days.
    (b) The term ``cyanide destruction unit'' shall mean a treatment 
system designed specifically to remove cyanide.



Sec. 439.2  Monitoring requirements.

    Unless otherwise noted, self-monitoring will be conducted at the 
final effluent discharge point.



              Subpart A--Fermentation Products Subcategory



Sec. 439.10  Applicability; description of the fermentation products subcategory.

    The provisions of this subpart are applicable to discharges 
resulting from the manufacture of pharmaceuticals by fermentation.



Sec. 439.11  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, 
abbreviations, and methods of analysis set forth in 40 CFR part 401 and 
Sec. 439.01 shall apply to this subpart.
    (b) The term ``product'' shall mean pharmaceutical products derived 
from fermentation processes.



Sec. 439.12  Effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology 
          currently available (BPT).

    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).
    (a) The following limitations establish the quantity or quality of 
pollutants or pollutant properties, controlled by this paragraph, which 
may be discharged by a fermentation products plant from a point source 
subject to the provisions of this paragraph after application of the 
best practicable control technology currently available:
    (1) The allowable effluent discharge limitation for the daily 
average mass of BOD5 in any calendar month shall be expressed in mass 
per unit time and shall specifically reflect not less than 90% reduction 
in the long term daily average raw waste content of BOD5 multiplied by a 
variability factor of 3.0.
    (2) The allowable effluent discharge limitation for the daily 
average mass of COD in any calendar month shall be expressed in mass per 
unit time and shall specifically reflect not less than 74 percent 
reduction in the long term daily average raw waste content of COD 
multiplied by a variability factor of 2.2.
    (3) The long term daily average raw waste load for the pollutants 
BOD5 and COD is defined as the average daily mass of each pollutant 
discharged in the influent to the wastewater treatment system over a 12 
consecutive month period within the most recent 36 months, which shall 
include the greatest production effort.
    (4) To assure equity in regulating discharges from the point sources 
covered by this subpart of the point source category, calculation of raw 
waste loads of BOD5 and COD for the purpose of determining NPDES permit 
limitations (i.e., the base numbers to which the percent reductions are 
applied) shall exclude any waste load associated with separable mycelia 
and solvents in those raw waste loads, except that residual amounts of 
mycelia and solvents remaining after the practice of recovery and/or 
separate disposal or reuse may be included in the calculation of the raw 
waste loads. These practices of removal, disposal, or reuse include 
physical separation and removal of separable mycelia, recovery of 
solvents from waste streams, incineration of concentrated solvent waste 
streams (including tar still bottoms), and broth concentration for 
disposal other than to the treatment system. This regulation does not 
prohibit inclusion of such waste in the raw waste loads in fact, nor 
does it mandate any specific practice, but rather describes the 
rationale for determining the permit conditions. These limits may be 
achieved by any of several or a combination thereof of programs and 
practices.
    (5) The pH shall be within the range of 6.0-9.0 standard units.

[[Page 263]]

    (6) The allowable effluent discharge limitation for the daily 
average mass of TSS in any calendar month shall be 1.7 times the BOD5 
limitation determined in paragraph (a)(1) of this section.
    (7) For those plants using or generating cyanide in the 
manufacturing process, the allowable effluent discharge for cyanide is 
shown below.
    (i) See table below:

    (ii) If all cyanide-containing waste streams are diverted to a 
cyanide destruction unit and the effluent from the cyanide destruction 
unit is discharged to a biological treatment system, self-monitoring 
must be conducted after cyanide treatment and before dilution with other 
streams. Alternatively, self-monitoring may be conducted at the final 
effluent discharge point, if the daily maximum cyanide limitation is 
multiplied by 0.18, the maximum 30 day average cyanide limitation is 
multiplied by 0.35, and both limitations are adjusted based on the 
dilution ratio of the cyanide-contaminated waste stream flow to the 
total process wastewater discharge flow. However, if all cyanide-
containing waste streams are not treated in a cyanide destruction unit 
or if the effluent from the cyanide destruction unit is not discharged 
to a biological treatment system, self-monitoring must be conducted at 
the final effluent discharge point and the daily maximum cyanide 
limitation must be multiplied by 0.18, the maximum 30 day average 
cyanide limitation must be multiplied by 0.35, and both limitations must 
be adjusted based on the dilution ratio of the cyanide-contaminated 
waste stream flow to the total process wastewater discharge flow. 
Permittees not using or generating cyanide must certify to the permit-
issuing authority that they are not using or generating this compound.
    (b) Dilution to meet the above effluent limitations may not be 
practiced.

               Subpart B--Extraction Products Subcategory



Sec. 439.20  Applicability; description of the extraction products subcategory.

    The provisions of this subpart are applicable to discharges 
resulting from the manufacture of pharmaceuticals by extraction.



Sec. 439.21  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, 
abbreviations, and methods of analysis set forth in 40 CFR part 401 and 
Sec. 439.01 shall apply to this subpart.
    (b) The term ``product'' shall mean biological and natural 
extraction products. This subcategory shall include blood fractions, 
vaccines, serums, animal bile derivatives, endocrine products, and 
isolation of medicinal products, such as alkaloids, from botanical drugs 
and herbs.



Sec. 439.22  Effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology 
          currently available (BPT).

    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).
    (a) The following limitations establish the quantity or quality of 
pollutants or pollutant properties, controlled by this paragraph, which 
may be discharged by an extraction products plant from a point source 
subject to the provisions of this paragraph after application of the 
best practicable control technology currently available:
    (1) The allowable discharge for the pollutant parameters BOD5 and 
COD shall be expressed in mass per unit time and shall represent the 
specified wastewater treatment efficiency in terms of a residual 
discharge associated with an influent to the wastewater treatment plant 
corresponding to the maximum production period for a given 
pharmaceutical plant as defined in paragraph (a)(4) of this section.
    (2) The allowable effluent discharge limitation for the daily 
average mass of BOD5 in any calendar month shall specifically reflect 
not less than 90 percent reduction in the long term daily average raw 
waste content of BOD5 multiplied by a variability factor of 3.0. 
However, a plant shall not be required to attain a maximum 30-day 
average BOD5 effluent limitation of less than the equivalent of 45 mg/l.
    (3) The allowable effluent discharge limitation for the daily 
average mass of COD in any calendar month shall specifically reflect not 
less than 74 percent reduction in the long term daily average raw waste 
content of COD multiplied by a variability factor of 2.2. However, a 
plant shall not be required to attain a maximum 30-day average COD 
effluent limitation of less than the equivalent of 220 mg/l.
    (4) The long term daily average raw waste load for the pollutants 
BOD5 and COD is defined as the average daily mass of each pollutant 
discharged in the influent to the wastewater treatment system over a 12 
consecutive month period within the most recent 36 months, which shall 
include the greatest production effort.
    (5) To assure equity in regulating discharges from the point sources 
covered by this subpart of the point source category, calculation of raw 
waste loads of BOD5 and COD for the purpose of determining NPDES permit 
limitations (i.e., the base numbers to which the percent reductions are 
applied) shall exclude any waste load associated with solvents in those 
raw waste loads, except that residual amounts of solvents remaining 
after the practice of recovery and/or separate disposal or reuse may be 
included in the calculation of the

[[Page 267]]

raw waste loads. Those practices of removal, disposal, or reuse include 
recovery of solvents from waste streams and incineration of concentrated 
solvent waste streams (including tar still bottoms). This regulation 
does not prohibit inclusion of such wastes in the raw waste loads in 
fact, nor does it mandate any specific practice, but rather describes 
the rationale for determining the permit conditions. These limits may be 
achieved by any one of several or a combination thereof of programs and 
practices.
    (6) The allowable effluent discharge limitation for the daily mass 
of TSS in any calendar month shall be 1.7 times the BOD5 limitation 
determined in paragraph (a)(2) of this section.
    (7) The pH shall be within the range of 6.0-9.0 standard units.
    (8) For those plants using or generating cyanide in the 
manufacturing process, the allowable effluent discharge for cyanide is 
shown below.

    (ii) If all cyanide-containing waste streams are diverted to a 
cyanide destruction unit and the effluent from the cyanide destruction 
unit is discharged to a biological treatment system, self-monitoring 
must be conducted after cyanide treatment and before dilution with other 
streams. Alternatively, self-monitoring may be conducted at the final 
effluent discharge point, if the daily maximum cyanide limitation is 
multiplied by 0.18, the maximum 30-day average cyanide limitation is 
multiplied by 0.35, and both limitations are adjusted based on the 
dilution ratio of the cyanide-contaminated waste stream flow to the 
total process wastewater discharge flow. However, if all cyanide-
containing waste streams are not treated in a cyanide destruction unit 
or if the effluent from the cyanide destruction unit is not discharged 
to a biological treatment system, self-monitoring must be conducted at 
the final effluent discharge point and the daily maximum cyanide 
limitation must be multiplied by 0.18, the maximum 30-day average 
cyanide limitation must be multiplied by 0.35, and both limitations must

Permittees not using or generating cyanide must certify to the permit-
issuing authority that they are not using or generating this compound.
    (b) Dilution to meet the above effluent limitations may not be 
practiced.

           Subpart C--Chemical Synthesis Products Subcategory



Sec. 439.30  Applicability; description of the chemical synthesis products subcategory.

    The provisions of this subpart are applicable to discharges 
resulting from the manufacture of pharmaceuticals by chemical synthesis.



Sec. 439.31  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, 
abbreviations, and methods of analysis set forth in 40 CFR part 401 and 
Sec. 439.01 of this chapter shall apply to this subpart.
    (b) The term ``product'' shall mean pharmaceutical products derived 
from chemical synthesis processes.



Sec. 439.32  Effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology 
          currently available (BPT).

    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).
    (a) The following limitations establish the quantity or quality of 
pollutants or pollutant properties, controlled by this paragraph, which 
may be discharged by a chemical synthesis plant from a point source 
subject to the provisions of this paragraph after application of the 
best practicable control technology currently available:
    (1) The allowable discharge for the pollutant parameters BOD5 and 
COD shall be expressed in mass per unit time and shall represent the 
specified wastewater treatment efficiency in terms of a residual 
discharge associated with an influent to the wastewater treatment plant 
corresponding to the maximum production period for a given 
pharmaceutical plant as defined in paragraph (a)(4) of this section.
    (2) The allowable effluent discharge limitation for the daily 
average mass of BOD5 in any calendar month shall specifically reflect 
not less than 90 percent reduction in the long term daily average raw 
waste content of BOD5 multiplied by a variability factor of 3.0.
    (3) The allowable effluent discharge limitation for the daily 
average mass of COD in any calendar month shall specifically reflect not 
less than 74 percent reduction in the long term daily average raw waste 
content of COD multiplied by a variability factor of 2.2.
    (4) The long term daily average raw waste load for the pollutant 
parameters BOD5 and COD is defined as the average daily mass of each 
pollutant discharged in the influent to the wastewater treatment system 
over a 12 consecutive month period within the most recent 36 months, 
which shall include the greatest production effort.
    (5) To assure equity in regulating discharges from the point sources 
covered by this subpart of the point source category, calculation of raw 
waste loads of BOD5 and COD for the purpose of determining NPDES permit 
limitations (i.e., the base numbers to which the percent reductions are 
applied) shall exclude any waste load associated with solvents in those 
raw waste loads, except that residual amounts of solvents remaining 
after the practice of recovery and/or separate disposal or reuse may be 
included in the calculation of the raw waste loads. These practices of 
removal, disposal, or reuse include recovery of solvents from waste 
streams and incineration of concentrated solvent waste streams 
(including tar still bottoms). This regulation does not prohibit 
inclusion of such wastes in the raw waste loads in fact, nor does it 
mandate any specific practice, but rather describes the rationale for 
determining the permit conditions. These limits may be achieved by any 
one of several or a combination thereof of programs and practices.

[[Page 271]]

    (6) The pH shall be within the range of 6.0 to 9.0 standard units.
    (7) The allowable effluent discharge limitation for the daily 
average mass of TSS in any calendar month shall be 1.7 times the BOD5 
limitation determined in paragraph (a)(2) of this section.
    (8) For those plants using or generating cyanide in the 
manufacturing process, the allowable effluent discharge for cyanide is 
shown below.

    (ii) If all cyanide-containing waste streams are diverted to a 
cyanide destruction unit and the effluent from the cyanide destruction 
unit is discharged to a biological treatment system, self-monitoring 
must be conducted after cyanide treatment and before dilution with other 
streams. Alternatively, self-monitoring may be conducted at the final 
effluent discharge point, if the daily maximum cyanide limitation is 
multiplied by 0.18, the maximum 30-day average cyanide limitation is 
multiplied by 0.35, and both limitations are adjusted based on the 
dilution ratio of the cyanide-contaminated waste stream flow to the 
total process wastewater discharge flow. However, if all cyanide-
containing waste streams are not treated in a cyanide destruction unit 
or if the effluent from the cyanide destruction unit is not discharged 
to a biological treatment system, self-monitoring must be conducted at 
the final effluent discharge point and the daily maximum cyanide 
limitation must be multiplied by 0.18, the maximum 30-day average 
cyanide limitation must be multiplied by 0.35, and both limitations must 
be adjusted based on the dilution ratio of the cyanide-contaminated 
waste stream flow to the total process wastewater discharge flow. 
Permittees not using or generating cyanide must certify to the permit-
issuing authority that they are not using or generating this compound.
    (b) Dilution to meet the above effluent limitations may not be 
practiced.

        Subpart D--Mixing/Compounding and Formulation Subcategory



Sec. 439.40  Applicability; description of the mixing/compounding and formulation subcategory.

    The provisions of this subpart are applicable to discharges 
resulting from mixing/compounding and formulaton operations of 
pharmaceutical products.



Sec. 439.41  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, 
abbreviations, and methods of analysis set forth in 40 CFR part 401 and 
Sec. 439.01 of this chapter shall apply to this subpart.
    (b) The term ``product'' shall mean products from plants which 
blend, mix, compound, and formulate pharmaceutical ingredients. 
Pharmaceutical preparations for human and veterinary use such as 
ampules, tablets, capsules, vials, ointments, medicinal powders, 
solutions, and suspensions are included.



Sec. 439.42  Effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology currently available (BPT).

    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).
    (a) The following limitations establish the quantity or quality of 
pollutants or pollutant properties, controlled by this paragraph, which 
may be discharged by a mixing/compounding and formulation plant from a 
point source subject to the provisions of this paragraph after 
application of the best practicable control technology currently 
available:
    (1) The allowable discharge for the pollutant parameters BOD5 and 
COD shall be expressed in mass per unit time and shall represent the 
specified wastewater treatment efficiency in terms of a residual 
discharge associated with an influent to the wastewater treatment plant 
corresponding to the maximum production period for a given 
pharmaceutical plant as defined in paragraph (a)(4) of this section.
    (2) The allowable effluent discharge limitation for the daily 
average mass of BOD5 in any calendar month shall specifically reflect 
not less than 90 percent reduction in the long term daily average raw 
waste content of BOD5 multiplied by a variability factor 3.0. However, a 
plant shall not be required to attain a maximum 30-day average BOD5 
effluent limitation of less than the equivalent of 45 mg/l.
    (3) The allowable effluent discharge limitation for the daily 
average mass of COD in any calendar month shall specifically reflect not 
less than 74 percent reduction in the long term daily average raw waste 
content of COD multiplied by a variability factor of 2.2. However, a 
plant shall not be required to attain a maximum 30-day average COD 
effluent limitation of less than the equivalent of 220 mg/l.
    (4) The long term daily average raw waste load for the pollutant 
parameters BOD5 and COD is defined as the average daily mass of each 
pollutant discharged in the influent to the wastewater treatment system 
over a 12 consecutive month period within the most recent 36 months, 
which shall include the greatest production effort.
    (5) To assure equity in regulating discharges from the point sources 
covered by this subpart of the point source category, calculation of raw 
waste loads of BOD5 and COD for the purpose of determining NPDES per 
limitations (i.e., the base numbers to which the percent reductions are 
applied) shall exclude any waste load associated with solvents in those 
raw waste loads except that residual amounts of solvents remaining after 
the practice of recovery and/or separate disposal or reuse may be 
included in the calculation of the

[[Page 275]]

raw waste loads. These practices of removal, disposal, or reuse include 
recovery of solvents from waste streams and incineration of concentrated 
solvent waste streams (including tar still bottoms). This regulation 
does not prohibit inclusion of such wastes in the raw waste loads in 
fact, nor does it mandate any specific practice, but rather describes 
the rationale for determining the permit conditions. These limits may be 
achieved by any one of several or a combination thereof of programs and 
practices.
    (6) The allowable effluent discharge limitation for the daily 
average mass of TSS in any calendar month shall be 1.7 times the BOD5 
limitation determined in paragraph (a)(2) of this section.
    (7) The pH shall be within the range of 6.0-9.0 standard units.
    (8) For those plants using or generating cyanide in the 
manufacturing process, the allowable effluent discharge for cyanide is 
shown below.

    (ii) If all cyanide-containing waste streams are diverted to a 
cyanide destruction unit and the effluent from the cyanide destruction 
unit is discharged to a biological treatment system, self-monitoring 
must be conducted after cyanide treatment and before dilution with other 
streams. Alternatively, self-monitoring may be conducted at the final 
effluent discharge point, if the daily maximum cyanide limitation is 
multiplied by 0.18, the maximum 30-day average cyanide limitation is 
multiplied by 0.35, and both limitations are adjusted based on the 
dilution ratio of the cyanide-contaminated waste stream flow to the 
total process wastewater discharge flow. However, if all cyanide-
containing waste streams are not treated in a cyanide destruction unit 
or if the effluent from the cyanide destruction unit is not discharged 
to a biological treatment system, self-monitoring must be conducted at 
the final effluent discharge point and the daily maximum cyanide 
limitation must be multiplied by 0.18, the maximum 30-day average 
cyanide limitation must be multiplied by 0.35, and both limitations must 
be adjusted based on the dilution ratio of the cyanide-contaminated 
waste stream flow to the total process wastewater discharge flow. 
Permittees not using or generating cyanide must certify to the permit-
issuing authority that they are not using or generating this compound.
    (b) Dilution to meet the above effluent limitations may not be 
practiced.

                     Subpart E--Research Subcategory



Sec. 439.50  Applicability; description of the research subcategory.

    The provisions of this subpart are applicable to discharges 
resulting from pharmaceutical research.



Sec. 439.51  Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, 
abbreviations, and methods of analysis set forth in in 40 CFR part 401 
and Sec. 439.01 shall apply to this subpart.
    (b) The term ``product'' shall mean products or services resulting 
from pharmaceutical research, which includes microbiological, 
biological, and chemical operations.



Sec. 439.52  Effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology 
          currently available (BPT).

    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).
    (a) The following limitations establish the quantity or quality of 
pollutants or pollutant properties, controlled by this paragraph, which 
may be discharged by a pharmaceutical research operation from a point 
source subject to the provisions of this paragraph after application of 
the best practicable control technology currently available:
    (1) The allowable discharge for the pollutant parameters BOD5 and 
COD shall be expressed in mass per unit time and shall represent the 
specified wastewater treatment efficiency in terms of a residual 
discharge associated with an influent to the wastewater treatment plant 
corresponding to the maximum production period for a given 
pharmaceutical plant as defined in paragraph (a)(4) of this section.
    (2) The allowable effluent discharge limitation for the daily 
average mass of BOD5 in any calendar month shall specifically reflect 
not less than 90 percent reduction in the long term daily average raw 
waste content of BOD5 multiplied by a variability factor of 3.0. 
However, a plant shall not be required to attain a maximum 30-day 
average BOD5 effluent limitation of less than the equivalent of 45 mg/l.
    (3) The allowable effluent discharge limitation for the daily 
average mass of COD in any calendar month shall specifically reflect not 
less than 74 percent reduction in the long term daily average raw waste 
content of COD multiplied by a variability factor of 2.2. However, a 
plant shall not be required to attain a maximum 30-day average COD 
effluent limitation of less than the equivalent of 220 mg/l.
    (4) The long term daily average raw waste load for the pollutant 
parameters BOD5 and COD is defined as the average daily mass of each 
pollutant influent to the wastewater treatment system over a 12 
consecutive month period within the most recent 36 months, which shall 
include the greatest production effort.
    (5) To assure equity in regulation discharges from the point sources 
covered by this subpart of the point source category, calculation of raw 
waste loads of BOD5 and COD for the purpose of determining NPDES permit 
limitations (i.e., the base numbers to which the percent reductions are 
applied) shall exclude

[[Page 279]]

any waste load associated with solvents in those raw waste loads, except 
that residual amounts of solvents remaining after the practice of 
recovery and/or separate disposal or reuse may be included in the 
calculation of the raw waste loads. These practices of removal, 
disposal, or reuse include recovery of solvents from waste streams and 
incineration of concentrated solvent waste streams (including tar still 
bottoms). This regulation does not prohibit inclusion of such wastes in 
the raw waste loads in fact, nor does it mandate any specific practice, 
but rather describes the rationale for determining the permit 
conditions. These limits may be achieved by any one of several or a 
combination thereof of programs and practices.
    (6) The allowable effluent discharge limitation for the daily 
average mass of TSS in any calendar month shall be 1.7 times the BOD5 
limitation determined in paragraph (a)(2) of this section.
    (7) The pH shall be within the range of 6.0-9.0 standard units.
    (b) Dilution to meet the above effluent limitations may not be 
practiced.

    (c)(1) Except as provided in paragraph (c) of this section, there 
shall be no discharge of process wastewater to navigable waters from 
mills that employ magnetic and physical methods to beneficiate iron ore 
in the Mesabi Range. The Agency recognizes that the elimination of the 
discharge of pollutants to navigable waters may result in an increase in 
discharges of some pollutants to other media. The Agency has considered 
these impacts and has addressed them in the preamble published on 
December 3, 1982.
    (2) In the event that the annual precipitation falling on the 
treatment facility and the drainage area contributing surface runoff to 
the treatment facility exceeds the annual evaporation, a volume of water 
equivalent to the difference between annual precipitation falling on the 
treatment facility and the drainage area contributing surface runoff to 
the treatment facility and annual evaporation may be discharged subject 
to the limitations set forth in paragraph (a) of this section.

    (b)(1) Except as provided in paragraph (b) of this section, there 
shall be no discharge of process wastewater to navigable waters from 
mills that use the froth-flotation process alone, or in conjunction with 
other processes, for the beneficiation of copper, lead, zinc, gold, 
silver, or molybdenum ores or any combination of these ores. The Agency 
recognizes that the elimination of the discharge of pollutants to 
navigable waters may result in an increase in discharges of some 
pollutants to other media. The Agency has considered these impacts and 
has addressed them in the preamble published on December 3, 1982.
    (2)(i) In the event that the annual precipitation falling on the 
treatment facility and the drainage area contributing surface runoff to 
the treatment facility exceeds the annual evaporation, a volume of water 
equal to the difference between annual precipitation falling on the 
treatment facility and the drainage area contributing surface runoff to 
the treatment facility and annual evaporation may be discharged subject 
to the limitations set forth in paragraph (a) of this section.
    (ii) In the event there is a build up of contaminants in the recycle 
water which significantly interferes with the

[[Page 298]]

ore recovery process and this interference can not be eliminated through 
appropriate treatment of the recycle water, the permitting authority may 
allow a discharge of process wastewater in an amount necessary to 
correct the interference problem after installation of appropriate 
treatment. This discharge shall be subject to the limitations of 
paragraph (a) of this section. The facility shall have the burden of 
demonstrating to the permitting authority that the discharge is 
necessary to eliminate interference in the ore recovery process and that 
the interference could not be eliminated through appropriate treatment 
of the recycle water.
    (c)(1) Except as provided in paragraph (c) of this section, there 
shall be no discharge of process wastewater to navigable waters from 
mine areas and mills processes and areas that use dump, heap, in-situ 
leach or vat-leach processes to extract copper from ores or ore waste 
materials. The Agency recognizes that the elimination of the discharge 
of pollutants to navigable waters may result in an increase in 
discharges of some pollutants to other media. The Agency has considered 
these impacts and has addressed them in the preamble published on 
December 3, 1982.
    (2) In the event that the annual precipitation falling on the 
treatment facility and the drainage area contributing surface runoff to 
the treatment facility exceeds the annual evaporation, a volume of water 
equal to the difference between annual precipitation falling on the 
treatment facility and the drainage area contributing surface runoff to 
the treatment facility and annual evaporation may be discharged subject 
to the limitations set forth in paragraph (a) of this section.
    (d)(1) Except as provided in paragraph (d) of this section, there 
shall be no discharge of process wastewater to navigable waters from 
mills that use the cyanidation process to extract gold or silver. The 
Agency recognizes that the elimination of the discharge of pollutants to 
navigable waters may result in an increase in discharges of some 
pollutants to other media. The Agency has considered these impacts and 
has addressed them in the preamble published on December 3, 1982.
    (2) In the event that the annual precipitation falling on the 
treatment facility and the drainage area contributing surface runoff to 
the treatment facility exceeds the annual evaporation, a volume of water 
equal to the difference between annual precipitation falling on the 
treatment facility and the drainage area contributing surface runoff to 
the treatment facility and annual evaporation may be discharged subject 
to the limitations set forth in paragraph (a) of this section.

              Subpart L--General Provisions and Definitions



Sec. 440.130  Applicability.

    Abbreviations and methods of analysis set forth in 40 CFR part 401 
shall apply to part 440 except as provided in these general provisions 
and definitions. The general provisions and definitions in this subpart 
apply to all subparts of part 440 unless otherwise noted.



Sec. 440.131  General provisions.

    (a) Combined waste streams. In the event that waste streams from 
various subparts or segments of subparts in part 440 are combined for 
treatment and discharge, the quantity and concentration of each 
pollutant or pollutant property in the combined discharge that is 
subject to effluent limitations shall not exceed the quantity and 
concentration of each pollutant or pollutant property that could have 
been discharged had each waste stream been treated separately. In 
addition, the discharge flow from the combined discharge shall not 
exceed the volume that could have been discharged had each waste stream 
been treated separately.
    (b) Storm exemption for facilities permitted to discharge. If, as a 
result of precipitation or snowmelt, a source with an allowable 
discharge under 40 CFR part 440 has an overflow or excess discharge of 
effluent which does not meet the limitations of 40 CFR part 440, the 
source may qualify for an exemption from such limitations with respect 
to such discharge if the following conditions are met:
    (1) The facility is designed, constructed and maintained to contain 
the maximum volume of wastewater which would be generated by the 
facility during a 24-hour period without an increase in volume from 
precipitation and the maximum volume of wastewater resulting from a 10-
year, 24-hour precipitation event or treat the maximum flow associated 
with these volumes. In computing the maximum volume of wastewater which 
would result from a 10-year, 24-hour precipitation event, the facility 
must include the volume which would result from all areas contributing 
runoff to the individual treatment facility, i.e., all runoff that is 
not diverted from the active mining area and runoff which is not 
diverted from the mill area.
    (2) The facility takes all reasonable steps to maintain treatment of 
the

[[Page 300]]

wastewater and minimize the amount of overflow.
    (3) The facility complies with the notification requirements of 
Sec. 122.60 (g) and (h). The storm exemption is designed to provide an 
affirmative defense to an enforcement action. Therefore, the operator 
has the burden of demonstrating to the appropriate authority that the 
above conditions have been met.
    (c) Storm exemption for facilities not permitted to discharge. If, 
as a result of precipitation (rainfall or snowmelt), a source which is 
not permitted to discharge under 40 CFR part 440, has an overflow or 
discharge which violates the limitations of 40 CFR part 440, the source 
may qualify for an exemption from such limitations with respect to such 
discharge if the following conditions are met:
    (1) The facility is designed, constructed, and maintained to contain 
the maximum volume of wastewater stored and contained by the facility 
during normal operating conditions without an increase in volume from 
precipitation and the maximum volume of wastewater resulting from a 10-
year, 24-hour precipitation event. In computing the maximum volume of 
wastewater which would result from a 10-year, 24-hour precipitation 
event, the facility must include the volume which would result from all 
areas contributing runoff to the individual treatment facility, i.e., 
all runoff that is not diverted from the area or process subject to zero 
discharge, and other runoff that is allowed to commingle with the 
influent to the treatment system.
    (2) The facility takes all reasonable steps to minimize the overflow 
or excess discharge.
    (3) The facility complies with the notification requirements of 
Sec. 122.60(g) and (h). The storm exemption is designed to provide an 
affirmative defense to an enforcement action. Therefore, the operator 
has the burden of demonstrating to the appropriate authority that the 
above conditions have been met.
    (d) pH adjustment. (1) Where the application of neutralization and 
sedimentation technology to comply with relevant metal limitations 
results in an inability to comply with the pH range of 6 to 9, the 
permit issuer may allow the pH level in the final effluent to slightly 
exceed 9.0 so that the copper, lead, zinc, mercury, and cadmium 
limitations will be achieved.
    (2) In the case of a discharge into natural receiving waters for 
which the pH, if unaltered by human activities, is or would be less than 
6.0 and approved water quality standards authorize such lower pH, the pH 
limitations for the discharge may be adjusted downward to the pH water 
quality criterion for the receiving waters provided the other effluent 
limitations for the discharge are met. In no case shall a pH limitation 
below 5.0 be permitted.
    (e) Groundwater infiltration provision. In the event a new source 
subject to a no discharge requirement can demonstrate that groundwater 
infiltration contributes a substantial amount of water to the tailing 
impoundment or wastewater holding facility, the permitting authority may 
allow the discharge of a volume of water equivalent to the amount of 
groundwater infiltration. This discharge shall be subject to the 
limitations for mine drainage applicable to the new source subcategory.

    For the purpose of this subpart M, the general definitions, 
abbreviations, methods of analysis, and general provisions set forth in 
40 CFR part 401 shall apply except as superseded by those below. The 
general provisions and definitions set forth in 40 CFR part 440, subpart 
L, shall not apply to this subpart.
    (a) Specialized definitions. The following specialized definitions 
apply to this subpart only.
    (1) ``Beneficiation area'' means the area of land used to stockpile 
ore immediately before the beneficiation process, the area of land used 
for the beneficiation process, the area of land used to stockpile the

beneficiation process.
    (14) ``Permit area'' means the area of land specified or referred to 
in an NPDES permit in which active mining and related activities may 
occur that result in the discharge regulated under the terms of the 
permit. Usually this is specifically delineated in an NPDES permit or 
permit application, but in other cases may be ascertainable from an 
Alaska Tri-agency permit application or similar document specifying the 
mine location, mining plan and similar data.
    (15) ``Plant site'' means the area occupied by the mine, necessary 
haulage ways from the mine to the beneficiation process, the 
beneficiation area, the area occupied by the wastewater treatment 
facilities and the storage areas for waste materials and solids removed 
from the wastewaters during treatment.
    (16) ``Process wastewater'' means all water used in and resulting 
from the beneficiation process, including but not limited to the water 
used to move the ore to and through the beneficiation process, the water 
used to aid in classification, and the water used in gravity separation,

organic or inorganic) which will settle in one hour expressed in 
milliliters per liter (ml/l) as determined using an Imhoff cone and the 
method described for Residue--Settleable in 40 CFR part 136.
    (b) Specialized provisions--storm exemption. This specialized 
provision applies to this subpart M only. If, as a result of 
precipitation (rainfall or snowmelt), a source subject to this subpart 
has an overflow or discharge of effluent which does not meet the 
limitations or standards of this subpart, the source may qualify for an 
exemption from such limitations and standards with respect

[[Page 303]]

to such discharge if the following conditions are met:
    (1) The treatment system is designed, constructed, and maintained to 
contain the maximum volume of untreated process wastewater which would 
be discharged, stored, contained and used or recycled by the 
beneficiation process into the treatment system during a 4-hour 
operating period without an increase in volume from precipitation or 
infiltration, plus the maximum volume of water runoff resulting from a 
5-year, 6-hour precipitation event. In computing the maximum volume of 
water which would result from a 5-year, 6-hour precipitation event, the 
operator must include the volume which would result from the plant site 
contributing runoff to the individual treatment facility.
    (2) The operator takes all reasonable steps to maintain treatment of 
the wastewater and minimize the amount of overflow.
    (3) The source is in compliance with the BMP in Sec. 140.148 and 
related provisions of its NPDES permit.
    (4) The operator complies with the notification requirements of 
Sec. 122.41 (m) and (n) of this title. The storm exemption is designed 
to provide an affirmative defense to an enforcement action. Therefore, 
the operator has the burden of demonstrating to the appropriate 
authority that the above conditions have been met.

such mining operation.
    (a) Surface water diversion: The flow of surface waters into the 
plant site shall be interrupted and these waters diverted around and 
away from incursion into the plant site.
    (b) Berm construction: Berms, including any pond walls, dikes, low 
dams and similar water retention structures shall be constructed in a 
manner such that they are reasonably expected to reject the passage of 
water.
    (c) Pollutant materials storage: Measures shall be taken to assure 
that pollutant materials removed from the process water and wastewater 
streams will be retained in storge areas and not discharged or released 
to the waters of the United States.
    (d) New water control: The amount of new water allowed to enter the 
plant site for use in ore processing shall be limited to the minimum 
amount required as make-up water for processing operations.
    (e) Maintenance of water control and solids retention devices: All 
water control devices such as diversion structures and berms and all 
solids retention structures such as berms, dikes, pond structures and 
dams shall be maintained to continue their effectiveness and to protect 
from unexpected and catastrophic failure.

Anhydride; Quinmethionate; Rotenone; Sulfoxide; Triazine compounds (both 
symmetrical and asymmetrical); and Warfarin and similar anticoagulants. 
Provided, however, that the effluent limitations of this subpart for 
BOD5 and TSS, but not COD, apply to manufacturers of Ametryn, Prometon, 
Prometryn, Terbutryn, Cyanazine, Atrazine, Propazine, Simazine, 
Terbuthylazine, Hexazinone, and Glyphosate.
    (b) For the purpose of calculating BPT effluent limitations for 
organic Pesticide chemicals, the provisions of

[[Page 318]]

this subpart are applicable to discharges resulting from the manufacture 
of the following organic active ingredients: Aldrin, BHC, Captan, 
Chlordane, DDD, DDE, DDT, Dichloran, Dieldrin, Endosulfan, Endrin, 
Heptachlor, Lindane, Methoxychlor, Mirex, PCNB, Toxaphene, Trifluralin,

Parathion Methyl, Parathion Ethyl, Aminocarb, Carbaryl, Methiocarb, 
Mexacarbate, Propoxur, Barban, Chlorpropham, Diuron, Fenuron, Fenuron-
TCA, Linuron, Monuron, Monuron-TCA, Neubron, Propham, Swep, 2,4-D, 
Dicamba, Silvex, 2,4,5-T, Siduron, Perthane, and Dicofol.
    (c) The intermediates used to manufacture the active ingredients and 
active ingredients used solely in experimental pesticides are excluded 
from coverage in this subpart. Insecticidal pathogenic organisms such as 
Bacillus thuringiensis, insect growth hormones, plant extracts such as 
pyrethrins; sex attractants and botanicals such as Rotenone are also 
excluded from BPT coverage in this subpart.
    (d) A plant that manufactures a pesticide active ingredient listed 
in Table 1 of this part must comply with the BAT effluent limitations 
and new source performance and pretreatment standards for that pesticide 
active ingredient listed in table 2 (BAT and PSES) or Table 3 of this 
part (NSPS and PSNS). A plant that manufactures a pesticide active 
ingredient listed in Table 1 of this part must also comply with the BAT 
effluent limitations and new source performance and pretreatment 
standards for priority pollutants listed in Tables 4, 5 and 6 of this 
part. The limitations in Table 4 of this part (BAT and NSPS) are 
applicable to existing and new direct discharge point sources that use 
End-of-Pipe biological treatment. The limitations in Table 5 of this 
part (BAT and NSPS) are applicable to existing and new direct discharge 
point sources that do not use end-of-pipe biological treatment. The 
limitations in Table 6 of this part (PSES and PSNS) are applicable to 
existing and new sources that discharge to Publicly Owned Treatment 
Works.
    (e) In the case of lead and total cyanide, the discharge quantity 
(mass) shall be determined by multiplying the concentrations listed in 
the applicable tables in this subpart times the flow from non-complexed 
lead-bearing waste streams for lead and times the flow from non-
complexed cyanide-bearing waste streams for total cyanide. Discharges of 
cyanide in cyanide-bearing waste streams are not subject to the cyanide 
limitation and standards of this subpart if the permit writer or control 
authority determines that the cyanide limitations and standards are not 
achievable due to elevated levels of non-amenable cyanide (i.e., cyanide 
that is not oxidized by chlorine treatment) that result from the 
unavoidable complexing of cyanide at the process source of the cyanide-
bearing waste stream and establishes an alternative total cyanide or 
amenable cyanide limitation that reflects the best available technology 
economically achievable. The determination must be based upon a review 
of relevant engineering, production, and sampling and analysis 
information, including measurements of both total and amenable cyanide 
in the waste stream. An analysis of the extent of complexing in the 
waste stream, based on the foregoing information, and its impact on 
cyanide treatability shall be set forth in writing and, for direct 
dischargers, be contained in the fact sheet required by 40 CFR 124.8.

             Subpart A--Photographic Processing Subcategory



Sec. 459.10   Applicability; description of the photographic processing subcategory.

    The provisions of this subpart are applicable to point source 
discharges resulting from the development or printing of paper prints, 
slides, negatives, enlargements, movie film, and other sensitized 
materials except that facilities processing 150 sq. meters (1600 sq. 
feet) per day or less are not covered. Both commercial and military 
facilities are covered by this subpart.



Sec. 459.11   Specialized definitions.

    For the purpose of this subpart:
    (a) Except as provided below, the general definitions, abbreviations 
and methods of analysis set forth in part 401 of this chapter shall 
apply to this subpart.

[[Page 338]]

    (b) The term ``product'' shall mean articles developed or printed by 
photographic processes, such as paper prints, slides, negatives, 
enlargements, movie film and other sensitized materials.



Sec. 459.12   Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best practicable control technology currently available.

    In establishing the limitations set forth in this section, EPA took 
into account all information it was able to collect, develop and solicit 
with respect to factors (such as age and size of plant, raw materials, 
manufacturing processes, products produced, treatment technology 
available energy requirements and costs) which can affect the industry 
subcategorization and effluent levels established. It is, however, 
possible that data which would affect these limitations have not been 
available and, as a result, these limitations should be adjusted for 
certain plants in this industry. An individual discharger or other 
interested person may submit evidence to the Regional Administrator (or 
to the State, if the State has the authority to issue NPDES permits) 
that factors relating to the equipment of facilities involved, the 
process applied, or other such factors related to such discharger are 
fundamentally different from the factors considered in the establishment 
of the guidelines. On the basis of such evidence or other available 
information, the Regional Administrator (or the State) will make a 
written finding that such factors are or are not fundamentally different 
for that facility compared to those specified in the Development 
Document. If such fundamentally different factors are found to exist, 
the Regional Administrator or the State shall establish for the 
discharger effluent limitations in the NPDES permit either more or less 
stringent than the limitations established herein, to the extent 
dictated by such fundamentally different factors. Such limitations must 
be approved by the Administrator of the Environmental Protection Agency. 
The Administrator may approve or disapprove such limitations, specify 
other limitations, or initiate proceedings to revise these regulations.
    (a) The following limitations establish the quantity or quality of 
pollutants or pollutant properties, controlled by this paragraph, which 
may be discharged from a photographic processing point source subject to 
the provisions of this paragraph after application of the best 
practicable control technology currently available:

Sec. 461.1  Applicability.

    This part applies to any battery manufacturing plant that discharges 
or may discharge a pollutant to waters of the United States or that 
introduces pollutants to a publicly owned treatment works. Battery 
manufacturing operations subject to regulation under this part shall not 
be subject to regulation under part 413 or 433.



Sec. 461.2  General definitions.

    In addition to the definitions set forth in 40 CFR part 401, the 
following definitions apply to this part:
    (a) ``Battery'' means a modular electric power source where part or 
all of the fuel is contained within the unit and electric power is 
generated directly from a chemical reaction rather than indirectly 
through a heat cycle engine. In this regulation there is no 
differentiation between a single cell and a battery.
    (b) ``Battery manufacturing operations'' means all of the specific 
processes used to produce a battery including the manufacture of anodes 
and cathodes and associated ancillary operations. These manufacturing 
operations are excluded from regulation under any other point source 
category.
    (c) ``Ancillary operations'' means all of the operations specific to 
battery manufacturing and not included specifically within anode or 
cathode manufacture (ancillary operations are primarily associated with 
battery assembly and chemical production of anode or cathode active 
materials).
    (d) ``Plate soak'' shall mean the process operation of soaking or 
reacting lead subcategory battery plates, that are more than 2.5 mm 
(0.100 in) thick, in sulfuric acid.
    (e) ``Discharge allowance'' means the amount of pollutant (mg per kg 
of production unit) that a plant will be permitted to discharge. For 
this category the allowances are specific to battery manufacturing 
operations.
    (f) ``Miscellaneous wastewater streams'' shall mean the combined 
wastewater streams from the process operations listed below for each 
subcategory. If a plant has one of these

[[Page 341]]

streams then the plant receives the entire miscellaneous waste stream 
allowance.
    (1) Cadmium subcategory. Cell wash, electrolyte preparation, floor 
and equipment wash, and employee wash.
    (2) Lead subcategory. Floor wash, wet air pollution control, battery 
repair, laboratory, hand wash, and respirator wash.
    (3) Lithium subcategory. Floor and equipment wash, cell testing, and 
lithium scrap disposal.
    (4) Zinc subcategory. Cell wash, electrolyte preparation, employee 
wash, reject cell handling, floor and equipment wash.
    (g) ``Trucked batteries'' shall mean batteries moved into or out of 
the plant by truck when the truck is actually washed in the plant to 
remove residues left in the truck from the batteries.



Sec. 461.3  Monitoring and reporting requirements.

    The ``monthly average'' regulatory values shall be the basis for the 
monthly average discharge in direct discharge permits and for 
pretreatment standards. Compliance with the monthly discharge limit is 
required regardless of the number of samples analyzed and averaged.



Sec. 461.4  Compliance date for PSES.

    The compliance date for pretreatment standards for existing sources 
is March 9, 1987.



                     Subpart A--Cadmium Subcategory



Sec. 461.10  Applicability; description of the cadmium subcategory.

    This subpart applies to discharges to waters of the United States, 
and introductions of pollutants into publicly owned treatment works from 
the manufacturing of cadmium anode batteries.



Sec. 461.11  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:

    (b) There shall be no discharge allowance for process wastewater 
pollutants from any battery manufacturing operation other than those 
battery manufacturing operations listed above.
    (c)(1) In cases where battery employee shower wastewater containing 
concentrations of lead exceeding 0.20 mg/l is combined with process 
wastewaters prior to treatment, the Control Authority may, for purposes 
of applying the Combined Wastestream Formula under Sec. 403.6(e) of this 
chapter, notwithstanding the provisions of Sec. 403.6(e), exercise its 
discretion and classify battery employee shower wastewater as an 
unregulated rather than a dilute (FD) wastestream.
    (2) Before the Control Authority may exercise its discretion to 
classify such a stream as an unregulated stream, the battery 
manufacturer must provide engineering, production, and sampling and 
analysis information sufficient to allow a determination by the Control 
Authority on how the stream should be classified.

                           General Provisions



Sec. 463.1  Applicability.

    (a) This part applies to any plastics molding and forming process 
that discharges or may discharge pollutants to waters of the United 
States or that introduces pollutants into a publicly owned treatment 
works. Plastics molding and forming processes include processes that 
blend, mold, form, or otherwise process plastic materials into 
intermediate or final plastic products. They include commonly recognized 
processes such as extrusion, molding, coating and laminating, 
thermoforming, calendering, casting, foaming, cleaning, and finishing.
    (b) Plastics molding and forming processes (e.g., extrusion and 
pelletizing) used by plastics resin manufacturers to process crude 
intermediate plastic material for shipment off-site are excluded from 
this regulation and regulated under the organic chemicals, plastics, and 
synthetic fibers category. Plastics molding and forming processes used 
by plastic resin manufacturers to process crude intermediate plastic 
materials, which are further processed on-site into intermediate or 
final plastics products in molding and forming processes, are controlled 
by the effluent limitations guidelines and standards for the plastics 
molding and forming category in this part.
    (c) Processes that coat a plastic material onto a substrate may fall 
within the definition of electroplating and metal finishing as defined 
in 40 CFR parts 413 and 433. These coating processes are excluded from 
the effluent limitations guidelines and standards for the electroplating 
and metal finishing point source categories and are subject to the 
plastics molding and forming regulation in this part.
    (d) Coating of plastic material onto a formed metal substrate is 
also covered by the plastics molding and forming effluent limitations 
guidelines and standards and is not covered by the specific metal 
forming guidelines such as aluminum forming (40 CFR part 467), copper 
forming (40 CFR part 468), and nonferrous metals forming (40 CFR part 
471). However, the plastics molding and forming effluent limitations 
guidelines and standards in this part apply only to the coating process; 
the metal forming operations are subject to the specific metal forming 
regulation.
    (e) Research and development laboratories that produce plastic 
products using a plastics molding and forming process are subject to the 
effluent limitations guidelines and standards in this part if the 
plastics molding and forming process discharges process water. The mass 
of plastic product produced in the plastics molding and forming process 
is not considered when determining the applicability of the plastics 
molding and forming regulation in this part to plastics molding and 
forming processes at research and development laboratories.
    (f) Chemical and thermal reticulation processes for polyurethane 
foam are not subject to the effluent limitations guidelines and 
standards in this part. Water used in those processes is not considered 
to be process water as defined in this regulation. Processes used to 
further mold or form the reticulated foam are subject, however, to this 
regulation if they discharge process water.
    (g) Processes used to regenerate cellulose and to produce a product 
(e.g., rayon) from the regenerated cellulose are not subject to the 
effluent limitations guidelines and standards in this part. Processes 
that mold or form cellulose derivatives (e.g., cellulose acetate) are 
subject to the effluent limitations guidelines and standards in this 
part if they discharge process water.

Sec. 463.2  General definitions.

    In addition to the definitions set forth in 40 CFR part 401, the 
following definitions apply to this part:
    (a) ``Plastics molding and forming'' is a manufacturing process in 
which plastic materials are blended, molded, formed, or otherwise 
processed into intermediate or final products.
    (b) ``Process water'' is any raw, service, recycled, or reused water 
that contacts the plastic product or contacts shaping equipment surfaces 
such as molds and mandrels that are, or have been, in contact with the 
plastic product.

[[Page 374]]

    (c) ``Contact cooling and heating water'' is process water that 
contacts the raw materials or plastic product for the purpose of heat 
transfer during the plastics molding and forming process.
    (d) ``Cleaning water'' is process water used to clean the surface of 
an intermediate or final plastic product or to clean the surfaces of 
equipment used in plastics molding and forming that contact an 
intermediate or final plastic product. It includes water used in both 
the detergent wash and rinse cycles of a cleaning process.
    (e) ``Finishing'' water is processed water used to remove waste 
plastic material generated during a finishing process or to lubricate a 
plastic product during a finishing process. It includes water used to 
machine or to assemble intermediate or final plastic products.
    (f) ``Plastic material'' is a synthetic organic polymer (i.e., a 
thermoset polymer, a thermoplastic polymer, or a combination of a 
natural polymer and a thermoset or thermoplastic polymer) that is solid 
in its final form and that was shaped by flow. The material can be 
either a homogeneous polymer or a polymer combined with fillers, 
plasticizers, pigments, stabilizers, or other additives.
    (g) ``Crude intermediate plastic material'' is plastic material 
formulated in an on-site polymerization process.
    (h) ``Mass of pollutant that can be discharged'' is the pollutant 
mass calculated by multiplying the pollutant concentration times the 
average process water usage flow rate.

    The ``monthly average'' regulatory values shall be the basis for the 
monthly average effluent limitations guidelines and standards in direct 
discharge permits. Compliance with the monthly average effluent 
limitations guidelines and standards is required regardless of the 
number of samples analyzed and averaged.



        Subpart A--Contact Cooling and Heating Water Subcategory



Sec. 463.10  Applicability; description of the contact cooling and heating water subcategory.

    This subpart applies to discharges of pollutants from processes in 
the contact cooling and heating water subcategory to waters of the 
United States and the introduction of such pollutants into publicly

                           General Provisions



Sec. 464.01  Applicability.

    (a) This part applies to metal molding and casting facilities that 
discharge or may discharge pollutants to waters of the United States or 
that introduce pollutants into a publicly owned treatment works.



Sec. 464.02  General definitions.

    In addition to the definitions set forth in 40 CFR part 401, the 
following definitions apply to this part:
    (a) Aluminum casting. The remelting of aluminum or an aluminum alloy 
to form a cast intermediate or final product by pouring or forcing the 
molten metal into a mold, except for ingots, pigs, or other cast shapes 
related to nonferrous (primary and secondary) metals manufacturing (40 
CFR part 421) and aluminum forming (40 CFR part 467). Processing 
operations following the cooling of castings not covered under aluminum 
forming, except for grinding scrubber operations which are covered here, 
are covered under the electroplating and metal finishing point source 
categories (40 CFR parts 413 and 433).
    (b) Copper casting. The remelting of copper or a copper alloy to 
form a cast intermediate or final product by pouring or forcing the 
molten metal into a mold, except for ingots, pigs, or other cast shapes 
related to nonferrous (primary and secondary) metals manufacturing (40 
CFR part 421). Also excluded are casting of beryllium alloys in which 
beryllium is present at 0.1 or greater percent by weight and precious 
metals alloys in which the precious

[[Page 380]]

metal is present at 30 or greater percent by weight. Except for grinding 
scrubber operations which are covered here, processing operations 
following the cooling of castings are covered under the electroplating 
and metal finishing point source categories (40 CFR parts 413 and 433).
    (c) Ferrous casting. The remelting of ferrous metals to form a cast 
intermediate or finished product by pouring the molten metal into a 
mold. Except for grinding scrubber operations which are covered here, 
processing operations following the cooling of castings are covered 
under the electroplating and metal finishing point source categories (40 
CFR parts 413 and 433).
    (d) Zinc casting. The remelting of zinc or zinc alloy to form a cast 
intermediate or final product by pouring or forcing the molten metal 
into a mold, except for ingots, pigs, or other cast shapes related to 
nonferrous (primary) metals manufacturing (40 CFR part 421) and 
nonferrous metals forming (40 CFR part 471). Processing operations 
following the cooling of castings not covered under nonferrous metals 
forming are covered under the electroplating and metal finishing point 
source categories (40 CFR parts 413 and 433).
    (e) POTW shall mean ``publicly owned treatment works.''
    (f) A non-continuous discharger is a plant which does not discharge 
pollutants during specific periods of time for reasons other than 
treatment plant upset, such periods being at least 24 hours in duration. 
A typical example of a non-continuous discharger is a plant where 
wastewaters are routinely stored for periods in excess of 24 hours to be 
treated on a batch basis. For non-continuous discharging direct 
discharging plants, NPDES permit authorities shall apply the mass-based 
annual average effluent limitations or standards and the concentration-
based maximum day and maximum for monthly average effluent limitations 
or standards established in the regulations. POTWs may elect to 
establish concentration-based standards for non-continuous discharges to 
POTWs. They may do so by establishing concentration-based pretreatment 
standards equivalent to the mass-based standards provided in 
Secs. 464.15, 464.16, 464.25, 464.26, 464.35, 464.36, 464.45, and 464.46 
of the regulations. Equivalent concentration standards may be 
established by following the procedures outlined in Sec. 464.03(b).
    (g) Total phenols shall mean total phenolic compounds as measured by 
the procedure listed in 40 CFR part 136 (distillation followed by 
colorimetric--4AAP).
    (h) Sm \3\ shall mean standard cubic meters.
    (i) SCF shall means standard cubic feet.
    (j) Total toxic organics (TTO) shall mean the sum of the mass of 
each of the toxic organic compounds which are found at a concentration 
greater than 0.010 mg/l. The specialized definitions for each subpart 
contain a discrete list of toxic organic compounds comprising TTO for 
each process segment in which TTO is regulated.



Sec. 464.03  Monitoring and reporting requirements.

    (a) As an alternative to monitoring for TTO (total toxic organics), 
an indirect discharging plant may elect to monitor for Oil and Grease 
instead. Compliance with the Oil and Grease standard shall be considered 
equivalent to complying with the TTO standard. Alternate Oil and Grease 
standards are provided as substitutes for the TTO standards provided in 
Secs. 464.15, 464.16, 464.25, 464.26, 464.35, 464.36, 464.45, and 
464.46.
    (b) POTWs may establish concentration standards rather than mass 
standards, but must ensure that the concentration standards are exactly 
equivalent to the mass-based standards provided in Secs. 464.15, 464.16, 
464.25, 464.26, 464.35, 464.36, 464.45, and 464.46. Equivalent 
concentration standards may be determined by multiplying the mass-based 
standards included in the regulations by an appropriate measurement of 
average production, raw material usage, or air scrubber flow (kkg of 
metal poured, kkg of sand reclaimed, or standard cubic meters of air 
scrubbed) and dividing by an appropriate measure of average discharge 
flow to the POTW, taking into account the proper conversion factors to 
ensure that the units (mg/l) are correct.
    (c) The ``monthly average'' regulatory values shall be the basis for 
the

[[Page 381]]

monthly average effluent limitations guidelines and standards in direct 
discharge permits and for pretreatment standards. Compliance with the 
monthly average effluent limitations guidelines and standards is 
required regardless of the number of samples analyzed and averaged.



Sec. 464.04  Compliance date for PSES.

    The compliance date of PSES is October 31, 1988.

Sec. 464.13  Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best available technology economically achievable.

    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 available technology economically 
achievable, except that non-continuous dischargers shall not be subject 
to the maximum day and maximum for monthly average mass (kg/1,000 kkg or 
lb/million lb of metal poured; kg/62.3 million Sm3 or lb/billion 
SCF of air scrubbed) effluent limitations for copper, lead, zinc, and 
total phenols. For non-continuous dischargers, annual average mass 
limitations and maximum day and maximum for monthly average 
concentration (mg/l) limitations shall apply. Concentration limitations 
and annual average mass limitations shall only apply to non-continuous 
dischargers.

Sec. 464.22  Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best practicable control technology currently available.

    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, except that non-continuous dischargers shall not be subject 
to the maximum day and maximum for monthly average mass (kg/1,000 kkg or 
lb/million lb of metal poured; kg/62.3 million Sm3 or lb/billion 
SCF of air scrubbed) effluent limitations for copper, lead, zinc, total 
phenols, oil and grease, and TSS. For non-continuous dischargers, annual 
average mass limitations and maximum day and maximum for monthly average 
concentration (mg/l) limitations shall apply. Concentration limitations 
and annual average mass limitations shall only apply to non-continuous 
dischargers.

    (b) Cast Iron. An iron containing carbon in excess of the solubility 
in the austentite that exists in the alloy at the eutectic temperature. 
Cast iron also is defined here to include any iron-carbon alloys 
containing 1.2 percent or more carbon by weight.
    (c) Ductile Iron. A cast iron that has been treated while molten 
with a master alloy containing an element such as magnesium or cerium to 
induce the formation of free graphite as nodules or spherules, which 
imparts a measurable degree of ductility to the cast metal.
    (d) Gray Iron. A cast iron that gives a gray fracture due to the 
presence of flake graphite.
    (e) Malleable Iron. A cast iron made by a prolonged anneal of white 
cast iron in which decarburization or graphitization, or both, take 
place to eliminate some or all of the cementite. Graphite is present in 
the form of temper carbon.
    (f) Steel. An iron-base alloy containing carbon, manganese, and 
often other alloying elements. Steel is defined here to include only 
those iron-carbon alloys containing less than 1.2 percent carbon by 
weight.
    (g) The ``primary metal cast'' shall mean the metal that is poured 
in the greatest quantity at an individual plant.
    (h) Multiple Ferrous Melting Furnace Scrubber Configuration. A 
multiple ferrous melting furnace scrubber configuration is a 
configuration where two or more discrete wet scrubbing devices are 
employed in series in a single melting furnace exhaust gas stream. The 
ferrous melting furnace scrubber mass allowance shall be given to each 
discrete wet scrubbing device that has an associated wastewater 
discharge in a multiple ferrous melting furnace scrubber configuration. 
The mass allowance for each discrete wet scrubber shall be identical and 
based on the air flow of the exhaust gas stream that passes through the 
multiple scrubber configuration.
    (i) Discrete Wet Scrubbing Device. A discrete wet scrubbing device 
is a distinct, stand-alone device that removes particulates and fumes 
from a contaminated gas stream by bringing the gas stream into contact 
with a scrubber liquor, usually water, and from which there is a 
wastewater discharge. Examples of discrete wet scrubbing devices are: 
Spray towers and chambers, venturi scrubbers (fixed and variable), wet 
caps, packed bed scrubbers, quenchers, and orifice scrubbers. Semi-wet 
scrubbing devices where water is added and totally evaporates prior to 
dry air pollution control are not considered to be discrete wet 
scrubbing devices. Ancillary scrubber operations such as fan washes and 
backwashes are not considered to be discrete wet scrubber devices. These 
ancillary operations are covered by the mass limitations of the 
associated scrubber. Aftercoolers are not considered to be discrete wet 
scrubbing devices, and water discharges from aftercooling are not 
regulated as a process wastewater in this category.



Sec. 464.32  Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best practicable control technology currently available.

    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, except that non-continuous dischargers shall not be subject 
to the maximum day and maximum for monthly average mass (kg/1,000 kkg or 
lb/million lb of metal poured; kg/1,000 kkg or lb/million lb of sand 
reclaimed; kg/62.3 million Sm3 or lb/billion SCF of air scrubbed) 
effluent limitations for copper, lead, zinc, total phenols, oil and 
grease, and TSS. For non-continuous dischargers,

[[Page 401]]

annual average mass limitations and maximum day and maximum for monthly 
average concentration (mg/l) limitations shall apply. Concentration 
limitations and annual average mass limitations shall only apply to non-
continuous dischargers.

Sec. 464.33  Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best available technology economically achievable.

    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 available technology economically 
achievable, except that non-continuous dischargers shall not be subject 
to the maximum day and maximum for monthly average mass (kg/1,000 kkg or 
lb/million lb of metal poured; kg/1,000 kkg or lb/million lb of sand 
reclaimed; kg/62.3 million Sm\3\ or lb/billion SCF of air scrubbed) 
effluent limitations for copper, lead, zinc, and total phenols. For non-
continuous dischargers, annual average mass limitations and maximum day 
and maximum for monthly average concentration (mg/l) limitations shall 
apply. Concentration limitations and annual average mass limitations 
shall only apply to non-continuous dischargers.
    (a) Casting Cleaning Operations. (1) Applicable to plants that are 
casting primarily ductile or gray iron and to plants that are casting 
primarily malleable iron where greater than 3,557 tons of metal are 
poured per year.

Sec. 464.43  Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best available technology economically achievable.

    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 available technology economically 
achievable, except that non-continuous dischargers shall not be subject 
to the maximum day and maximum for monthly average mass (kg/1,000 kkg or 
lb/million lb of metal poured; kg/62.3 million Sm 3 or lb/billion 
SCF of air scrubbed) effluent limitations for copper, lead, zinc, and 
total phenols. For non-continuous dischargers, annual average mass 
limitations and maximum day and maximum for monthly average 
concentration (mg/1) limitations shall apply. Concentration limitations 
and annual average mass limitations shall only apply to non-continuous 
dischargers.

facilities controlled by this regulation.
    (a) Periodic analyses for cyanide are not required when both of the 
following conditions are met:
    (1) The first wastewater sample taken in each calendar year has been 
analyzed and found to contain less than 0.07 mg/l cyanide
    (2) The owner or operator of the coil coating facility certifies in 
writing to the POTW authority or permit issuing authority that cyanide 
is not used in the coil coating process.
    (b) The ``monthly average'' regulatory values shall be the basis for 
the monthly average discharge limits in direct discharge permits and for 
pretreatment standards. Compliance with the monthly discharge limit is 
required regardless of the number of samples analyzed and averaged.
    (c) The following determination method shall be used for the 
determination of the concentration of oil and grease in wastewater 
samples from all subcategories of coil coating (Based on Standard 
Methods, 15th Edition, Methods 503A and 503E). In this method, a 
partition gravimetric procedure is used to determine hydrocarbon 
(petroleum based) oil and grease (O&G-E).

Sec. 466.01  Applicability.

    (a) Except as provided in paragraphs (b) and (c) of this section, 
the provisions of this part apply to any porcelain enameling facility 
which discharges pollutants to waters of the United States or introduces 
pollutants into a publicly owned treatment works.
    (b) Any existing porcelain enameling facility which prepares or 
coats less than 1600 m\2\/day and which introduces less than 60,000 1/
day of wastewater into a publicly owned treatment works is not 
controlled by the pretreatment standards for existing sources 
established by this regulation. Such facilities must comply with the 
provisions of 40 CFR part 403.
    (c) This part does not apply to the porcelain enameling on precious 
metal basis material.
    (d) When wastewaters from coating cast iron are cotreated with 
wastewaters from coating steel, the limitations for coating steel 
contained in Sec. 466.11 may be applied to the entire wastestream.

Sec. 466.02  General definitions.

    In addition to the definitions set forth in 40 CFR part 401, the 
following definitions apply to this part:
    (a) ``Porcelain enameling'' means the entire process of applying a 
fused vitreous enamel coating to a metal basis material. Usually this 
includes metal preparation and coating operations.
    (b) ``Basis material'' means the metal part or base onto which 
procelain enamel is applied.
    (c) ``Area processed'' means the total basis material area exposed 
to processing solutions.
    (d) ``Area coated'' means the area of basis material covered by each 
coating of enamel.
    (e) ``Coating operations'' means all of the operations associated 
with preparation and application of the vitreous coating. Usually this 
includes ballmilling, slip transport, application of slip to the 
workpieces, cleaning and recovery of faulty parts, and firing (fusing) 
of the enamel coat.

[[Page 436]]

    (f) ``Metal preparation'' means any and all of the metal processing 
steps preparatory to applying the enamel slip. Usually this includes 
cleaning, pickling and applying a nickel flash or chemical coating.
    (g) The term ``control authority'' is defined as the POTW if it has 
an approved pretreatment program; in the absence of such a program, the 
NPDES state if it has an approved pretreatment program or EPA if the 
State does not have an approved program.
    (h) The term ``precious metal'' means gold, silver, or platinum 
group metals and the principal alloys of those metals.



Sec. 466.03  Monitoring and reporting requirements.

    (a) Periodic analyses for chromium as may be required under part 122 
or 403 of this chapter is not required when both of the following 
conditions are met.
    (1) The first wastewater sample of each calendar year has been 
analyzed and found to contain less than 0.08 mg/l chromium.
    (2) The owner or operator of the porcelain enameling facility 
certifies in writing to the control authority or permit issuing 
authority that chromium is not contained in the raw materials or process 
chemicals of that facility and will not be used in the facility.
    (b) The ``monthly average'' regulatory values shall be the basis for 
the monthly average discharge in direct discharge permits and for 
pretreatment standards. Compliance with the monthly discharge limit is 
required regardless of the number of samples analyzed and averaged.

                           General Provisions



Sec. 467.01  Applicability.

    (a) Aluminum forming includes commonly recognized forming operations 
such as rolling, drawing, extruding, and forging and related operations 
such as heat treatment, casting, and surface treatments. Surface 
treatment of aluminum is any chemical or electrochemical treatment 
applied to the surface of aluminum. Such surface treatment is considered 
to be a part of aluminum forming whenever it is performed as an integral 
part of aluminum forming. For the purposes of this regulation, surface 
treatment of aluminum is considered to be an integral part of aluminum 
forming whenever it is performed at the same plant site at which 
aluminum is formed and such operations are not considered for regulation 
under the Electroplating and Metal Finishing provisions of 40 CFR parts 
413 and 433. Casting aluminum when performed as an integral part of 
aluminum forming and located on-site at an aluminum forming plant is 
considered an aluminum forming operation and is covered under these 
guidelines. When aluminum forming is performed on the same site as 
primary aluminum reduction the casting shall be regulated by the 
nonferrous metals guidelines if there is no cooling of the aluminum 
prior to casting. If the aluminum is cooled prior to casting then the 
casting shall be regulated by the aluminum forming guidelines.
    (b) This part applies to any aluminum forming facility, except for 
plants identified under paragraph (c) of this section, which discharges 
or may discharge pollutants to waters of the United States or which 
introduces or may introduce pollutants into a publicly owned treatment 
works.

[[Page 445]]

    (c) This part is applicable to indirect discharging aluminum forming 
plants that extrude less than 3 million pounds of product per year and 
draw, with emulsions or soaps, less than 1 million pounds per year.

    Note: This paragraph is promulgated as an Interim Final Rule.

[48 FR 49149, Oct. 24, 1983; 49 FR 11631, Mar. 27, 1984]



Sec. 467.02  General definitions.

    In addition to the definitions set forth in 40 CFR part 401, the 
following definitions apply to this part:
    (a) Aluminum forming is a set of manufacturing operations in which 
aluminum and aluminum alloys are made into semifinished products by hot 
or cold working.
    (b) Ancillary operation is a manufacturing operation that has a 
large flow, discharges significant amounts of pollutants, and may not be 
present at every plant in a subcategory, but when present is an integral 
part of the aluminum forming process.
    (c) Contact cooling water is any wastewater which contacts the 
aluminum workpiece or the raw materials used in forming aluminum.
    (d) Continuous casting is the production of sheet, rod, or other 
long shapes by solidifying the metal while it is being poured through an 
open-ended mold using little or no contact cooling water. Continuous 
casting of rod and sheet generates spent lubricants and rod casting also 
generates contact cooling water.
    (e) Degassing is the removal of dissolved hydrogen from the molten 
aluminum prior to casting. Chemicals are added and gases are bubbled 
through the molten aluminum. Sometimes a wet scrubber is used to remove 
excess chlorine gas.
    (f) Direct chill casting is the pouring of molten aluminum into a 
water-cooled mold. Contact cooling water is sprayed onto the aluminum as 
it is dropped into the mold, and the aluminum ingot falls into a water 
bath at the end of the casting process.
    (g) Drawing is the process of pulling metal through a die or 
succession of dies to reduce the metal's diameter or alter its shape. 
There are two aluminum forming subcategories based on the drawing 
process. In the drawing with neat oils subcategory, the drawing process 
uses a pure or neat oil as a lubricant. In the drawing with emulsions or 
soaps subcategory, the drawing process uses an emulsion or soap solution 
as a lubricant.
    (h) Emulsions are stable dispersions of two immiscible liquids. In 
the aluminum forming category this is usually an oil and water mixture.
    (i) Cleaning or etching is a chemical solution bath and a rinse or 
series of rinses designed to produce a desired surface finish on the 
workpiece. This term includes air pollution control scrubbers which are 
sometimes used to control fumes from chemical solution baths. Conversion 
coating and anodizing when performed as an integral part of the aluminum 
forming operations are considered cleaning or etching operations. When 
conversion coating or anodizing are covered here they are not subject to 
regulation under the provisions of 40 CFR Part 433, Metal Finishing.
    (j) Extrusion is the application of pressure to a billet of 
aluminum, forcing the aluminum to flow through a die orifice. The 
extrusion subcategory is based on the extrusion process.
    (k) Forging is the exertion of pressure on dies or rolls surrounding 
heated aluminum stock, forcing the stock to change shape and in the case 
where dies are used to take the shape of the die. The forging 
subcategory is based on the forging process.
    (l) Heat treatment is the application of heat of specified 
temperature and duration to change the physical properties of the metal.
    (m) Hot water seal is a heated water bath (heated to approximately 
180 deg. F) used to seal the surface coating on formed aluminum which 
has been anodized and coated. In establishing an effluent allowance for 
this operation, the hot water seal shall be classified as a cleaning or 
etching rinse.
    (n) In-process control technology is the conservation of chemicals 
and water throughout the production operations to reduce the amount of 
wastewater to be discharged.
    (o) Neat oil is a pure oil with no or few impurities added. In 
aluminum

[[Page 446]]

forming its use is mostly as a lubricant.
    (p) Rolling is the reduction in thickness or diameter of a workpiece 
by passing it between lubricated steel rollers. There are two 
subcategories based on the rolling process. In the rolling with neat 
oils subcategory, pure or neat oils are used as lubricants for the 
rolling process. In the rolling with emulsions subcategory, emulsions 
are used as lubricants for the rolling process.
    (q) The term Total Toxic Organics (TTO) shall mean the sum of the 
masses or concentrations of each of the following toxic organic 
compounds which is found in the discharge at a concentration greater 
than 0.010 mg/1:

p-chloro-m-cresol
2-chlorophenol
2,4-dinitrotoluene
1,2-diphenylhydrazine
ethyblenzene
fluoranthene
isophorone
napthalene
N-nitro sodi phenyl amine
phenol
benzo(a) pyrene
benzo(ghi)perylene

endrin
endrin aldehyde
PCB-1242, 1254, 1221
PCB-1232, 1248, 1260, 1016
acenaphthene

    (r) Stationary casting is the pouring of molten aluminum into molds 
and allowing the metal to air cool.
    (s) Wet scrubbers are air pollution control devices used to remove 
particulates and fumes from air by entraining the pollutants in a water 
spray.
    (t) BPT means the best practicable control technology currently 
available under section 304(b)(1) of the Act.
    (u) BAT means the best available technology economically achievable 
under section 304(b)(2)(B) of the Act.
    (v) BCT means the best conventional pollutant control technology, 
under section 304(b)(4) of the Act.
    (w) NSPS means new source performance standards under section 306 of 
the Act.
    (x) PSES means pretreatment standards for existing sources, under 
section 307(b) of the Act.
    (y) PSNS means pretreatment standards for new sources, under section 
307(c) of the Act.
    (z) The production normalizing mass (/kkg) for each core or 
ancillary operation is the mass (off-kkg or off-lb) processed through 
that operation.
    (aa) The term off-kilogram (off-pound) shall mean the mass of 
aluminum or aluminum alloy removed from a forming or ancillary operation 
at the end of a process cycle for transfer to a different machine or 
process.

53 FR 52369, Dec. 27, 1988]



Sec. 467.03  Monitoring and reporting requirements.

    The following special monitoring and reporting requirements apply to 
all facilities controlled by this regulation.
    (a) Periodic analyses for cyanide as may be required under part 122 
or 403 of this chapter are not required when both of the following 
conditions are met:
    (1) The first wastewater sample of each calender year has been 
analyzed and found to contain less than 0.07 mg/l cyanide.
    (2) The owner or operator of the aluminum forming plant certifies in 
writing to the POTW authority or permit issuing authority that cyanide 
is not and will not be used in the aluminum forming process.
    (b) As an alternative monitoring procedure for pretreatment, the 
POTW user may measure and limit oil and grease to the levels shown in 
pretreatment standards in lieu of measuring and regulating total toxic 
organics (TTO).
    (c) The ``monthly average'' regulatory values shall be the basis for 
the monthly average discharge limits in direct discharge permits and for 
pretreatment standards. Compliance

[[Page 447]]

with the monthly discharge limit is required regardless of the number of 
samples analyzed and averaged.

(Information collection requirements in paragraph (a) were approved by 
the Office of Management and Budget under control number 2040-0033)

reduction attainable by the application of the best conventional 
pollutant control technology.  [Reserved]



                    Subpart C--Extrusion Subcategory



Sec. 467.30  Applicability; description of the extrusion subcategory.

    This subpart applies to discharges of pollutants to waters of the 
United States and introductions of pollutants into publicly owned 
treatment works from the core and the ancillary operations of the 
extrusion subcategory.



Sec. 467.31  Specialized definitions.

    For the purpose of this subpart:
    (a) The ``core'' of the extrusion subcategory shall include 
extrusion die

[[Page 460]]

cleaning, dummy block cooling, stationary casting, artificial aging, 
annealing, degreasing, and sawing.
    (b) The term ``extrusion die cleaning'' shall mean the process by 
which the steel dies used in extrusion of aluminum are cleaned. The term 
includes a dip into a concentrated caustic bath to dissolve the aluminum 
followed by a water rinse. It also includes the use of a wet scrubber 
with the die cleaning operation.
    (c) The term ``ancillary operation'' shall mean any operation not 
previously included in the core, performed on-site, following or 
preceding the extrusion operation. The ancillary operations shall 
include direct chill casting, press or solution heat treatment, cleaning 
or etching, degassing, and extrusion press hydraulic fluid leakage.



Sec. 467.32  Effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology 
          currently available.

    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:

Sec. 469.13  Monitoring.

    (a) In lieu of monitoring for TTO, the permitting authority may 
allow direct dischargers to include the following certification as a 
``comment'' on the Discharge Monitoring Report required by Sec. 122.44 
(i), formerly Sec. 122.62(i): ``Based on my inquiry of the person or 
persons directly responsible for managing compliance with the permit 
limitation for total toxic organics (TTO), I certify that, to the best 
of my knowledge and belief, no dumping of concentrated toxic organics 
into the wastewaters has occurred since filing the last discharge 
monitoring report. I further certify that this facility is implementing 
the solvent management plan submitted to the permitting authority.''
    (b) In requesting that no monitoring of TTO be required, the direct 
discharger shall submit a solvent management plan that specifies to the 
permitting authority's satisfaction the toxic organic compounds used; 
the method of disposal used instead of dumping, such as reclamation, 
contract hauling, or incineration; and procedures for assuring that 
toxic organics do not routinely spill or leak into the wastewater. The 
permitting authority shall incorporate the plan as a provision of the 
permit.
    (c) In lieu of monitoring for TTO, the control authority may allow 
industrial users of POTWs to make the following certification as a 
comment to the periodic reports required by Sec. 403.12(e): ``Based on 
my inquiry of the person or persons directly responsible for managing 
compliance with the pretreatment standard for total toxic organics 
(TTO), I certify that, to the best of my knowledge and belief, no 
dumping of concentrated toxic organics into the wastewaters has occurred 
since filing the last discharge monitoring report. I further certify 
that this facility is implementing the solvent management plan submitted 
to the control authority.''
    (d) In requesting that no monitoring be required, industrial users 
of POTWs shall submit a solvent management plan that specifies to the 
control authority's satisfaction the toxic organic compounds used; the 
method of disposal used instead of dumping, such as reclamation, 
contract hauling, or incineration; and procedures for assuring that 
toxic organics do not routinely spill or leak into the wastewater.

Sec. 471.01  Applicability.

    (a) This part applies to discharges of pollutants to waters of the 
United States and introduction of pollutants into a publicly owned 
treatment works from the forming of nonferrous metals (including 
nonferrous metal alloys), except beryllium, copper, and aluminum and 
their alloys. Aluminum alloys are defined as any alloy in which aluminum 
is the major constituent in percent by weight. Copper alloys are defined 
as any alloy in which copper is the major constituent in percent by 
weight except when copper is alloyed with precious metals. Any copper-
precious metal alloy containing 30 percent or greater precious metal is 
considered a precious metal alloy for the purposes of this part. 
Beryllium alloys are any alloy in which beryllium is present at 0.1 
percent or greater. This part applies to:
    (1) Forming operations, including rolling (both hot and cold), 
extruding, forging, drawing, swaging, cladding, and tube reducing, and
    (2) Ancillary operations performed as an integral part of the 
forming of these metals, including casting for subsequent forming, heat 
treatment, surface treatment, alkaline cleaning, solvent degreasing, 
product testing, surface coating, sawing, grinding, tumbling, 
burnishing, and wet air pollution control.
    (b) This part also applies to discharges of pollutants to waters of 
the United States and introduction of pollutants into a publicly owned 
treatment works from mechanical metal powder production operations, 
forming of parts from metal powders, and associated ancillary operations 
(listed in paragraph (a)(2) of this section) of:
    (1) Iron, copper, and aluminum, and their alloys; and
    (2) The nonferrous metals and their alloys described in paragraph 
(a) of this section. This part does not regulate the production of metal 
powders by chemical means such as precipitation. The production of metal 
powder as the final step in refining metal is regulated under the 
Nonferrous Metals Manufacturing Point Source Category regulation, 40 CFR 
part 421.
    (c) Surface treatment includes any chemical or electrochemical 
treatment applied to the surface of the metal. For the purposes of this 
regulation, surface treatment of metals is considered to be an integral 
part of the forming of metals whenever it is performed at the

[[Page 514]]

same plant site at which the metals are formed. Such surface treatment 
operations are not regulated under the Electroplating or Metal Finishing 
Point Source Category regulations, 40 CFR part 413 or 433, respectively.
    (d) Casting is covered by this part when it is performed as an 
integral part of the metal forming process and takes place at the same 
plant site at which metals are formed. Such casting will not be 
regulated under the provisions of Metal Molding and Casting Point Source 
Category regulations, 40 CFR part 464.
    (e) This part does not apply to the forming of the metals cadmium, 
chromium, gallium, germanium, indium, lithium, manganese, neodymium, or 
praseodymium.



Sec. 471.02  General definitions.

    In addition to the definitions set forth in 40 CFR part 401, the 
following definitions apply to this part:
    (a) ``Nonferrous metal'' is any pure metal other than iron or any 
metal alloy for which a metal other than iron is its major constituent 
in percent by weight.
    (b) ``Forming'' is a set of manufacturing operations in which metals 
and alloys are made into semifinished products by hot or cold working.
    (c) ``Alkaline cleaning'' uses a solution (bath), usually detergent, 
to remove lard, oil, and other such compounds from a metal surface. 
Alkaline cleaning is usually followed by a water rinse. The rinse may 
consist of single or multiple stage rinsing. For the purposes of this 
part, an alkaline cleaning operation is defined as a bath followed by a 
rinse, regardless of the number of rinse stages. Each alkaline cleaning 
bath and rinse combination is entitled to a discharge allowance.
    (d) ``Atomization'' is the process in which a stream of water or gas 
impinges upon a molten metal stream, breaking it into droplets which 
solidify as powder particles.
    (e) ``Burnishing'' is a surface finishing process in which minute 
surface irregularities are displaced rather than removed.
    (f) ``Casting'' is pouring molten metal into a mold to produce an 
object of desired shape.
    (g) ``Cladding'' or ``metal cladding'' is the art of producing a 
composite metal containing two or more layers that have been 
metallurgically bonded together by roll bonding (co-rolling), solder 
application (or brazing), or explosion bonding.
    (h) ``Contact cooling water'' is any wastewater which contacts the 
metal workpiece or the raw materials used in forming metals for the 
purpose of removing heat from the metal.
    (i) ``Continuous casting'' is the production of sheet, rod, or other 
long shapes by solidifying the metal while it is being poured through an 
open-ended mold.
    (j) ``Degreasing'' is the removal of oils and greases from the 
surface of the metal workpiece. This process can be accomplished with 
detergents as in alkaline cleaning or by the use of solvents.
    (k) ``Direct chill casting'' is the pouring of molten nonferrous 
metal into a water-cooled mold. Contact cooling water is sprayed onto 
the metal as it is dropped into the mold, and the metal ingot falls into 
a water bath at the end of the casting process.
    (l) ``Drawing'' is the process of pulling a metal through a die or 
succession of dies to reduce the metal's diameter or alter its cross-
sectional shape.
    (m) ``Dye penetrant testing'' is a nondestructive method for finding 
discontinuities that are open to the surface of the metal. A dye is 
applied to the surface of metal and the excess is rinsed off. Dye that 
penetrates surface discontinuities will not be rinsed away thus marking 
these discontinuities.
    (n) ``Emulsions'' are stable dispersions of two immiscible liquids. 
In the Nonferrous Metals Forming and Metal Powders Point Source 
category, this is usually an oil and water mixture.
    (o) ``Electrocoating'' is the electrodeposition of a metallic or 
nonmetallic coating onto the surface of a workpiece.
    (p) ``Extrusion'' is the application of pressure to a billet of 
metal, forcing the metal to flow through a die orifice.
    (q) ``Forging'' is deforming metal, usually hot, with compressive 
force into desired shapes, with or without dies. Where dies are used, 
the metal is forced to take the shape of the die.

[[Page 515]]

    (r) ``Grinding'' is the process of removing stock from a workpiece 
by the use of a tool consisting of abrasive grains held by a rigid or 
semi-rigid grinder. Grinding includes surface finishing, sanding, and 
slicing.
    (s) ``Heat treatment'' is the application of heat of specified 
temperature and duration to change the physical properties of the metal.
    (t) ``Hot pressing'' is forming a powder metallurgy compact at a 
temperature high enough to effect concurrent sintering.
    (u) ``Hydrotesting'' is the testing of piping or tubing by filling 
with water and pressurizing to test for integrity.
    (v) ``Impregnation'' is the process of filling pores of a formed 
powder part, usually with a liquid such as a lubricant, or mixing 
particles of a nonmetallic substance in a matrix of metal powder.
    (w) ``In-process control technology'' is the conservation of 
chemicals and water throughout the production operations to reduce the 
amount of wastewater to be discharged.
    (x) ``Metal powder production'' operations are mechanical process 
operations which convert metal to a finely divided form.
    (y) ``Milling'' is the mechanical treatment of a nonferrous metal to 
produce powder, or to coat one component of a powder mixture with 
another.
    (z) ``Neat oil'' is a pure oil with no or few impurities added. In 
nonferrous metals forming, its use is mostly as a lubricant.
    (aa) ``Powder forming'' includes forming and compressing powder into 
a fully dense finished shape, and is usually done within closed dies.
    (bb) ``Precious metals'' include gold, platinum, palladium, and 
silver and their alloys. Any alloy containing 30 or greater percent by 
weight of precious metals is considered a precious metal alloy.
    (cc) ``Product testing'' includes operations such as dye penetrant 
testing, hydrotesting, and ultrasonic testing.
    (dd) ``Refractory metals'' includes the metals of columbium, 
tantalum, molybdenum, rhenium, tungsten and vanadium and their alloys.
    (ee) ``Rolling'' is the reduction in thickness or diameter of a 
workpiece by passing it between lubricated steel rollers.
    (ff) ``Roll bonding'' is the process by which a permanent bond is 
created between two metals by rolling under high pressure in a bonding 
mill (co-rolling).
    (gg) ``Sawing'' is cutting a workpiece with a band, blade, or 
circular disc having teeth.
    (hh) ``Shot casting'' is the production of shot by pouring molten 
metal in finely divided streams to form spherical particles.
    (ii) ``Stationary casting'' is the pouring of molten metal into 
molds and allowing the metal to cool.
    (jj) ``Surface treatment'' is a chemical or electrochemical 
treatment applied to the surface of a metal. Such treatments include 
pickling, etching, conversion coating, phosphating, and chromating. 
Surface treatment baths are usually followed by a water rinse. The rinse 
may consist of single or multiple stage rinsing. For the purposes of 
this part, a surface treatment operation is defined as a bath followed 
by a rinse, regardless of the number of stages. Each surface treatment 
bath, rinse combination is entitled to discharge allowance.
    (kk) ``Swaging'' is a process in which a solid point is formed at 
the end of a tube, rod, or bar by the repeated blows of one or more 
pairs of opposing dies.
    (ll) ``Tube reducing'' is an operation which reduces the diameter 
and wall thickness of tubing with a mandrel and a pair of rolls with 
tapered grooves.
    (mm) ``Tumbling'' or ``barrel finishing'' is an operation in which 
castings, forgings, or parts pressed from metal powder are rotated in a 
barrel with ceramic or metal slugs or abrasives to remove scale, fins, 
or burrs. It may be done dry or with an aqueous solution.
    (nn) ``Ultrasonic testing'' is a nondestructive test which applies 
sound, at a frequency above about 20 HJz, to metal, which has been 
immersed in liquid (usually water) to locate inhomogeneities or

control devices used to remove particulates and fumes from air by 
entraining the pollutants in a water spray.

[[Page 516]]

    (pp) ``Grab sample'' is a single sample which is collected at a time 
and place most representative of total discharge.
    (qq) ``Composite sample'' is a sample composed of no less than eight 
grab samples taken over the compositing period.
    (rr) A ``flow proportional composite sample'' is composed of grab 
samples collected continuously or discretely in proportion to the total 
flow at time of collection or to the total flow since collection of the 
previous grab sample. The grab volume or frequency of grab collection 
may be varied in proportion to flow.
    (ss) The term ``control authority'' is defined as the POTW if it has 
an approved pretreatment program; in the absence of such a program, the 
NPDES State if it has an approved pretreatment program or EPA if the 
State does not have an approved program.
    (tt) ``Continuous operations'' means that the industrial user

    (1) There shall be no discharge of process wastewater pollutants 
except as provided under paragraph (d)(2) of this section.
    (2) Process wastewater pollutants may be discharged, with no 
allowance for any pollutants discharged, provided the facility owner or 
operator demonstrates, on the basis of analytical methods set forth in 
or approved pursuant to 40 CFR part 136, that the concentrations of 
nitrosamine compounds in the wastewater discharged from the tube 
reducing process do not exceed 0.050 mg/l of N-nitrosodimethylamine, 
0.020 mg/l of N-nitrosodiphenylamine, and 0.020 mg/l of N-nitrosodi-n-
propylamine.
    (3) The demonstration required under paragraph (d)(2) of this 
section shall be made once per month until the demonstration has been 
made for all three nitrosamine compounds for six consecutive months, 
after which time the demonstration may be made once per quarter. If a 
sample is found to contain

[[Page 534]]

any of the foregoing nitrosamine compounds at concentrations greater 
than those specified in paragraph (d)(2) of this section, the actions 
described in paragraph (d)(4) of this section shall be taken, and the 
demonstration required under paragraph (d)(2) of this section shall be 
made once per month until it has been made for all three nitrosamine 
compounds for six consecutive months.
    (4) If sampling results show that any of the foregoing nitrosamine 
compounds is present in the process wastewater at concentrations greater 
than those specified in paragraph (d)(2) of this section, the facility 
owner or operator shall ensure that, within thirty days of receiving 
written notification of the sampling results, there is no further 
discharge of tube reducing spent lubricant wastewater until the owner or 
operator:
    (i) Performs a subsequent analysis which demonstrates that the 
concentrations of the foregoing nitrosamine compounds do not exceed the 
levels specified in paragraph (d)(2) of this section; or
    (ii) Substitutes a new tube reducing lubricant and thereafter 
complies with the requirements of paragraph (d)(3) of this section; or
    (iii) Determines the source of the pollutant whose concentration

    (d) Tube Reducing Spent Lubricant--Subpart C--BAT.
    (1) There shall be no discharge of process wastewater pollutants 
except as provided under paragraph (d)(2) of this section.
    (2) Process wastewater pollutants may be discharged, with no 
allowance for any pollutants discharged, provided the facility owner or 
operator demonstrates, on the basis of analytical methods set forth in 
or approved pursuant to 40 CFR part 136, that the concentrations of 
nitrosamine compounds in the wastewater discharged from the tube 
reducing process do not exceed 0.050 mg/l of N-nitrosodimethylamine, 
0.020 mg/l of N-nitrosodiphenylamine, and 0.020 mg/l of N-nitrosodi-n-
propylamine.
    (3) The demonstration required under paragraph (d)(2) of this 
section shall be made once per month until the demonstration has been 
made for all three nitrosamine compounds for six consecutive months, 
after which time the demonstration may be made once per quarter. If a 
sample is found to contain any of the foregoing nitrosamine compounds at 
concentrations greater than those specified in subparagraph (d)(2) of 
this section, the actions described in paragraph (d)(4) of this section 
shall be taken, and the demonstration required under subparagraph (d)(2) 
of this section shall be made once per month until it has been made for 
all three nitrosamine compounds for six consecutive months.
    (4) If sampling results show that any of the foregoing nitrosamine 
compounds is present in the process wastewater at concentrations greater 
than those specified in subparagraph (d)(2) of this section, the 
facility owner or operator shall ensure that, within thirty days of 
receiving written notification of the sampling results, there is no 
further discharge of tube reducing spent lubricant wastewater until the 
owner or operator:
    (i) Performs a subsequent analysis which demonstrates that the 
concentrations of the foregoing nitrosamine compounds do not exceed the 
levels specified in paragraph (d)(2) of this section; or
    (ii) Substitutes a new tube reducing lubricant and thereafter 
complies with the requirements of paragraph (d)(3) of this section; or
    (iii) Determines the source of the pollutant whose concentration 
exceeded the level specified in paragraph (d)(2) of this section and 
demonstrates to the satisfaction of the NPDES issuing authority that 
such source has been eliminated.
    (5) The concentration limits specified in paragraph (d)(2) of this 
section apply at the point of discharge from the tube reducing process. 
However, sampling after the tube reducing wastewater has been commingled 
with other wastewaters is permitted if:
    (i) Any dilution caused by the other wastewaters is taken into 
account in determining the appropriate (i.e., lower) allowable discharge 
concentration; and
    (ii) An analytical method of sufficient sensitivity is used to 
measure the

[[Page 539]]

levels of each of the foregoing nitrosamine compounds in the wastewaters 
being sampled.
    (e) Drawing spent neat oils--Subpart C--BAT. There shall be no 
discharge of process wastewater pollutants.
    (f) Drawing spent emulsions.

    (d) Tube Reducing Spent Lubricant--Subpart C--NSPS.
    (1) There shall be no discharge of process wastewater pollutants 
except as provided under paragraph (d)(2) of this section.
    (2) Process wastewater pollutants may be discharged, with no 
allowance for any pollutants discharged, provided the facility owner or 
operator demonstrates, on the basis of analytical methods set forth in 
or approved pursuant to 40 CFR part 136, that the concentrations of 
nitrosamine compounds in the wastewater discharged from the tube 
reducing process  do  not  exceed  0.050  mg/l  of N-
nitrosodimethylamine, 0.020 mg/l of N-nitrosodiphenylamine, and 0.020 
mg/l of N-nitrosodi-n-propylamine.
    (3) The demonstration required under paragraph (d)(2) of this 
section shall be made once per month until the demonstration has been 
made for all three nitrosamine compounds for six consecutive months, 
after which time the demonstration may be made once per quarter. If a 
sample is found to contain any of the foregoing nitrosamine compounds at 
concentrations greater than those specified in paragraph (d)(2) of this 
section, the actions described in paragraph (d)(4) of this section shall 
be taken, and the demonstration required under paragraph (d)(2) of this 
section shall be made once per month until it has been made for all 
three nitrosamine compounds for six consecutive months.
    (4) If sampling results show that any of the foregoing nitrosamine 
compounds is present in the process wastewater at concentrations greater 
than those specified in paragraph (d)(2) of this section, the facility 
owner or operator shall ensure that, within thirty days of receiving 
written notification of the sampling results, there is no further 
discharge of tube reducing spent lubricant wastewater until the owner or 
operator:
    (i) Performs a subsequent analysis which demonstrates that the 
concentrations of the foregoing nitrosamine compounds do not exceed the 
levels specified in paragraph (d)(2) of this section; or
    (ii) Substitutes a new tube reducing lubricant and thereafter 
complies with the requirements of paragraph (d)(3) of this section; or
    (iii) Determines the source of the pollutant whose concentration 
exceeded the level specified in paragraph (d)(2) of this section and 
demonstrates to the satisfaction of the NPDES issuing authority that 
such source has been eliminated.
    (5) The concentration limits specified in paragraph (d)(2) of this 
section apply at the point of discharge from the tube reducing process. 
However, sampling after the tube reducing wastewater has been commingled 
with other wastewaters is permitted if:
    (i) Any dilution caused by the other wastewaters is taken into 
account in determining the appropriate (i.e., lower) allowable discharge 
concentration; and
    (ii) An analytical method of sufficient sensitivity is used to 
measure the levels of each of the foregoing nitrosamine compounds in the 
wastewaters being sampled.

    (d) Tube Reducing Spent Lubricant--Subpart C--PSES.
    (1) There shall be no discharge of process wastewater pollutants 
except as provided under paragraph (d)(2) of this section.
    (2) Process wastewater pollutants may be discharged, with no 
allowance for any pollutants discharged, provided the facility owner or 
operator demonstrates, on the basis of analytical methods set forth in 
or approved pursuant to 40 CFR part 136, that the concentrations of 
nitrosamine compounds in the wastewater discharged from the tube 
reducing process  do  not  exceed  0.050  mg/l  of N-
nitrosodimethylamine, 0.020 mg/l of N-nitrosodiphenylamine, and 0.020 
mg/l of N-nitrosodi-n-propylamine.
    (3) The demonstration required under paragraph (d)(2) of this 
section shall be

[[Page 547]]

made once per month until the demonstration has been made for all three 
nitrosamine compounds for six consecutive months, after which time the 
demonstration may be made once per quarter. If a sample is found to 
contain any of the foregoing nitrosamine compounds at concentrations 
greater than those specified in paragraph (d)(2) of this section, the 
actions described in paragraph (d)(4) of this section shall be taken, 
and the demonstration required under paragraph (d)(2) of this section 
shall be made once per month until it has been made for all three 
nitrosamine compounds for six consecutive months.
    (4) If sampling results show that any of the foregoing nitrosamine 
compounds is present in the process wastewater at concentrations greater 
than those specified in paragraph (d)(2) of this section, the facility 
owner or operator shall ensure that, within thirty days of receiving 
written notification of the sampling results, there is no further 
discharge of tube reducing spent lubricant wastewater until the owner or 
operator:
    (i) Performs a subsequent analysis which demonstrates that the 
concentrations of the foregoing nitrosamine compounds do not exceed the 
levels specified in paragraph (d)(2) of this section; or
    (ii) Substitutes a new tube reducing lubricant and thereafter 
complies with the requirements of paragraph (d)(3) of this section; or
    (iii) Determines the source of the pollutant whose concentration 
exceeded the level specified in paragraph (d)(2) of this section and 
demonstrates to the satisfaction of the POTW control authority that such 
source has been eliminated.
    (5) The concentration limits specified in paragraph (d)(2) of this 
section apply at the point of discharge from the tube reducing process. 
However, sampling after the tube reducing wastewater has been commingled 
with other wastewaters is permitted if:
    (i) Any dilution caused by the other wastewaters is taken into 
account in determining the appropriate (i.e., lower) allowable discharge 
concentration; and
    (ii) An analytical method of sufficient sensitivity is used to 
measure the levels of each of the foregoing nitrosamine compounds in the 
wastewaters being sampled.
    (e) Drawing spent neat oils--Subpart C--PSES. There shall be no 
discharge of process wastewater pollutants.
    (f) Drawing spent emulsions.

    (d) Tube Reducing Spent Lubricant--Subpart C--PSNS.
    (1) There shall be no discharge of process wastewater pollutants 
except as provided under paragraph (d)(2) of this section
    (2) Process wastewater pollutants may be discharged, with no 
allowance for any pollutants discharged, provided the facility owner or 
operator demonstrates, on the basis of analytical methods set forth in 
or approved pursuant to 40 CFR part 136, that the concentrations of 
nitrosamine compounds in the wastewater discharged from the tube 
reducing process do not exceed 0.050 mg/l of  N-nitrosodimethylamine, 
0.020 mg/l of N-nitrosodiphenylamine, and 0.020 mg/l of N-nitrosodi-n-
propylamine.
    (3) The demonstration required under subparagraph (d)(2) of this 
section shall be made once per month until the demonstration has been 
made for all three nitrosamine compounds for six consecutive months, 
after which time the demonstration may be made once per

quarter. If a sample is found to contain any of the foregoing 
nitrosamine compounds at concentrations greater than those specified in 
paragraph (d)(2) of this section, the actions described in paragraph 
(d)(4) of this section shall be taken, and the demonstration required 
under paragraph (d)(2) of this section shall be made once per month 
until it has been made for all three nitrosamine compounds for six 
consecutive months.
    (4) If sampling results show that any of the foregoing nitrosamine 
compounds is present in the process wastewater at concentrations greater 
than those specified in subparagraph (d)(2) of this section, the 
facility owner or operator shall ensure that, within thirty days of 
receiving written notification of the sampling results, there is no 
further discharge of tube reducing spent lubricant wastewater until the 
owner or operator:
    (i) Performs a subsequent analysis which demonstrates that the 
concentrations of the foregoing nitrosamine compounds do not exceed the 
levels specified in paragraph (d)(2) of this section (2); or
    (ii) Substitutes a new tube reducing lubricant and thereafter 
complies with the requirements of paragraph (d)(3) of this section; or
    (iii) Determines the source of the pollutant whose concentration 
exceeded the level specified in subparagraph (2) above and demonstrates 
to the satisfaction of the POTW control authority that such source has 
been eliminated.
    (5) The concentration limits specified in paragraph (d)(2) of this 
section apply at the point of discharge from the tube reducing process. 
However, sampling after the tube reducing wastewater has been commingled 
with other wastewaters is permitted if:
    (i) Any dilution caused by the other wastewaters is taken into 
account in determining the appropriate (i.e., lower) allowable discharge 
concentration; and
    (ii) An analytical method of sufficient sensitivity is used to 
measure the levels of each of the foregoing nitrosamine compounds in the 
wastewaters being sampled.
    (e) Drawing spent neat oils--Subpart C--PSNS. There shall be no 
discharge of process wastewater pollutants.
    (f) Drawing spent emulsions.

    (g) Tube Reducing Spent Lubricant--Subpart I--BPT.
    (1) There shall be no discharge of process wastewater pollutants 
except as provided under paragraph (g)(2) of this section.
    (2) Process wastewater pollutants may be discharged, with no 
allowance for any pollutants discharged, provided the facility owner or 
operator demonstrates, on the basis of analytical methods set forth in 
or approved pursuant to 40 CFR part 136, that the concentrations of 
nitrosamine compounds in the wastewater discharged from the tube 
reducing process do not exceed 0.050 mg/l of N-nitrosodimethylamine, 
0.020 mg/l of N-nitrosodiphenylamine, and 0.020 mg/l of N-nitrosodi-n-
propylamine.
    (3) The demonstration required under subparagraph (g)(2) of this 
section shall be made once per month until the demonstration has been 
made for all three nitrosamine compounds for six consecutive months, 
after which time the demonstration may be made once per quarter. If a 
sample is found to contain any of the foregoing nitrosamine compounds at 
concentrations greater than those specified in subparagraph (g)(2) of 
this section, the actions described in paragraph (g)(4), of this section 
shall be taken, and the demonstration required under paragraph (g)(2) of 
this section shall be made once per month until it has been made for all 
three nitrosamine compounds for six consecutive months.
    (4) If sampling results show that any of the foregoing nitrosamine 
compounds is present in the process wastewater at concentrations greater 
than those specified in subparagraph (g)(2) of this section, the 
facility owner or operator shall ensure that, within thirty days of 
receiving written notification of the sampling results, there is no 
further discharge of tube reducing spent lubricant wastewater until the 
owner or operator:
    (i) Performs a subsequent analysis which demonstrates that the 
concentrations of the foregoing nitrosamine compounds do not exceed the 
levels specified in paragraph (g)(2) of this section; or
    (ii) Substitutes a new tube reducing lubricant and thereafter 
complies with the requirements of paragraph (g)(3) of this section; or
    (iii) Determines the source of the pollutant whose concentration 
exceeded the level specified in paragraph (g)(2) of this section and 
demonstrates to the satisfaction of the NPDES issuing authority that 
such source has been eliminated.
    (5) The concentration limits specified in paragraph (g)(2) of this 
section apply at the point of discharge from the tube reducing process. 
However, sampling after the tube reducing wastewater has been commingled 
with other wastewaters is permitted if:
    (i) Any dilution caused by the other wastewaters is taken into 
account in determining the appropriate (i.e.,

[[Page 615]]

lower) allowable discharge concentration; and
    (ii) An analytical method of sufficient sensitivity is used to 
measure the levels of each of the foregoing nitrosamine compounds in the 
wastewaters being sampled.
    (h) Surface treatment spent baths.

sample is found to contain any of the foregoing nitrosamine compounds at 
concentrations greater than those specified in paragraph (g)(2) of this 
section, the actions described in paragraph (g)(4) of this section shall 
be taken, and the demonstration required under paragraph (g)(2) of this 
section shall be made once per month until it has been made for all 
three nitrosamine compounds for six consecutive months.
    (4) If sampling results show that any of the foregoing nitrosamine 
compounds is present in the process wastewater at concentrations greater 
than those specified in paragraph (g)(2) of this section, the facility 
owner or operator shall ensure that, within thirty days of receiving 
written notification of the sampling results, there is no further 
discharge of tube reducing spent lubricant wastewater until the owner or 
operator:
    (i) Performs a subsequent analysis which demonstrates that the 
concentrations of the foregoing nitrosamine compounds do not exceed the 
levels specified in paragraph (g)(2) of this section; or
    (ii) Substitutes a new tube reducing lubricant and thereafter 
complies with the requirements of paragraph (g)(3) of this section; or
    (iii) Determines the source of the pollutant whose concentration 
exceeded the level specified in paragraph (g)(2) of this section and 
demonstrates to the satisfaction of the NPDES issuing authority that 
such source has been eliminated.
    (5) The concentration limits specified in paragraph (g)(2) of this 
section apply at the point of discharge from the tube reducing process. 
However, sampling after the tube reducing wastewater has been commingled 
with other wastewaters is permitted if:
    (i) Any dilution caused by the other wastewaters is taken into 
account in

[[Page 618]]

determining the appropriate (i.e., lower) allowable discharge 
concentration; and
    (ii) An analytical method of sufficient sensitivity is used to 
measure the levels of each of the foregoing nitrosamine compounds in the 
wastewaters being sampled.
    (h) Surface treatment spent baths.

    (g) Tube Reducing Spent Lubricant--Subpart I--NSPS:
    (1) There shall be no discharge of process wastewater pollutants 
except as provided under paragraph (g)(2) of this section.
    (2) Process wastewater pollutants may be discharged, with no 
allowance for any pollutants discharged, provided

[[Page 620]]

the facility owner or operator demonstrates, on the basis of analytical 
methods set forth in or approved pursuant to 40 CFR part 136, that the 
concentrations of nitrosamine compounds in the wastewater discharged 
from the tube reducing process do not exceed 0.050 mg/l of N-
nitrosodimethylamine, 0.020 mg/l of N-nitrosodiphenylamine, and 0.020 
mg/l of N-nitrosodi-n-propylamine.
    (3) The demonstration required under paragraph (g)(2) of this 
section shall be made once per month until the demonstration has been 
made for all three nitrosamine compounds for six consecutive months, 
after which time the demonstration may be made once per quarter. If a 
sample is found to contain any of the foregoing nitrosamine compounds at 
concentrations greater than those specified in paragraph (g)(2) of this 
section, the actions described in paragraph (g)(4) of this section shall 
be taken, and the demonstration required under paragraph (g)(2) of this 
section shall be made once per month until it has been made for all 
three nitrosamine compounds for six consecutive months.
    (4) If sampling results show that any of the foregoing nitrosamine 
compounds is present in the process wastewater at concentrations greater 
than those specified in paragraph (g)(2) of this section, the facility 
owner or operator shall ensure that, within thirty days of receiving 
written notification of the sampling results, there is no further 
discharge of tube reducing spent lubricant wastewater until the owner or 
operator:
    (i) Performs a subsequent analysis which demonstrates that the 
concentrations of the foregoing nitrosamine compounds do not exceed the 
levels specified in paragraph (g)(2) of this section; or
    (ii) Substitutes a new tube reducing lubricant and thereafter 
complies with the requirements of paragraph (g)(3) of this section; or
    (iii) Determines the source of the pollutant whose concentration 
exceeded the level specified in paragraph (g)(2) of this section and 
demonstrates to the satisfaction of the NPDES issuing authority that 
such source has been eliminated.
    (5) The concentration limits specified in paragraph (g)(2) of this 
section apply at the point of discharge from the tube reducing process. 
However, sampling after the tube reducing wastewater has been commingled 
with other wastewaters is permitted if:
    (i) Any dilution caused by the other wastewaters is taken into 
account in determining the appropriate (i.e., lower) allowable discharge 
concentration; and
    (ii) An analytical method of sufficient sensitivity is used to 
measure the levels of each of the foregoing nitrosamine compounds in the 
wastewaters being sampled.
    (h) Surface treatment spent baths.

    (g) Tube Reducing Spent Lubricant--Subpart I--PSES.
    (1) There shall be no discharge of process wastewater pollutants 
except as provided under paragraph (g)(2) of this section.
    (2) Process wastewater pollutants may be discharged, with no 
allowance for any pollutants discharged, provided the facility owner or 
operator demonstrates, on the basis of analytical methods set forth in 
or approved pursuant to 40 CFR part 136, that the concentrations of 
nitrosamine compounds in the wastewater discharged from the tube 
reducing process  do  not  exceed  0.050  mg/l  of N-
nitrosodimethylamine, 0.020 mg/l of N-nitrosodiphenylamine,

[[Page 623]]

and 0.020 mg/l of N-nitrosodi-n-propylamine.
    (3) The demonstration required under paragraph (g)(2) of this 
section shall be made once per month until the demonstration has been 
made for all three nitrosamine compounds for six consecutive months, 
after which time the demonstration may be made once per quarter. If a 
sample is found to contain any of the foregoing nitrosamine compounds at 
concentrations greater than those specified in subparagraph (g)(2) of 
this section, the actions described in paragraph (g)(4) of this section 
shall be taken, and the demonstration required under subparagraph (g)(2) 
of this section shall be made once per month until it has been made for 
all three nitrosamine compounds for six consecutive months.
    (4) If sampling results show that any of the foregoing nitrosamine 
compounds is present in the process wastewater at concentrations greater 
than those specified in subparagraph (g)(2) of this section, the 
facility owner or operator shall ensure that, within thirty days of 
receiving written notification of the sampling results, there is no 
further discharge of tube reducing spent lubricant wastewater until the 
owner or operator:
    (i) Performs a subsequent analysis which demonstrates that the 
concentrations of the foregoing nitrosamine compounds do not exceed the 
levels specified in paragraph (g)(2) of this section; or
    (ii) Substitutes a new tube reducing lubricant and thereafter 
complies with the requirements of paragraph (g)(3) of this section; or
    (iii) Determines the source of the pollutant whose concentration 
exceeded the level specified in paragraph (g)(2) of this section and 
demonstrates to the satisfaction of the POTW control authority that such 
source has been eliminated.
    (5) The concentration limits specified in paragraph (g)(2) of this 
section apply at the point of discharge from the tube reducing process. 
However, sampling after the tube reducing wastewater has been commingled 
with other wastewaters is permitted if:
    (i) Any dilution caused by the other wastewaters is taken into 
account in determining the appropriate (i.e., lower) allowable discharge 
concentration; and
    (ii) An analytical method of sufficient sensitivity is used to 
measure the levels of each of the foregoing nitrosamine compounds in the 
wastewaters being sampled.
    (h) Surface treatment spent baths.

    (g) Tube Reducing Spent Lubricant--Subpart I--PSNS.
    (1) There shall be no discharge of process wastewater pollutants 
except as provided under paragraph (g)(2) of this section.
    (2) Process wastewater pollutants may be discharged, with no 
allowance for any pollutants discharged, provided the facility owner or 
operator demonstrates, on the basis of analytical methods set forth in 
or approved pursuant to 40 CFR part 136, that the concentrations of 
nitrosamine compounds in the wastewater discharged from the tube 
reducing process  do  not  exceed  0.050  mg/l  of N-
nitrosodimethylamine, 0.020 mg/l of N-nitrosodiphenylamine, and 0.020 
mg/l of N-nitrosodi-n-propylamine.
    (3) The demonstration required under subparagraph (g)(2) of this 
section shall be made once per month until the demonstration has been 
made for all three nitrosamine compounds for six consecutive months, 
after which time the demonstration may be made once per quarter. If a 
sample is found to contain any of the foregoing nitrosamine compounds at 
concentrations greater than those specified in subparagraph (g)(2) of 
this section, the actions described in paragraph (g)(4) of this section 
shall be taken, and the demonstration required under paragraph (g)(2) 
shall be made once per month until it has been made for all three 
nitrosamine compounds for six consecutive months.
    (4) If sampling results show that any of the foregoing nitrosamine 
compounds is present in the process wastewater at concentrations greater 
than those specified in subparagraph (g)(2) of this section, the 
facility owner or operator shall ensure that, within thirty days of 
receiving written notification of the sampling results, there is no 
further discharge of tube reducing spent lubricant wastewater until the 
owner or operator:
    (i) Performs a subsequent analysis which demonstrates that the 
concentrations of the foregoing nitrosamine compounds do not exceed the 
levels specified in paragraph (g)(2) of this section; or
    (ii) Substitutes a new tube reducing lubricant and thereafter 
complies with the requirements of paragraph (g)(3) of this section; or
    (iii) Determines the source of the pollutant whose concentration 
exceeded the level specified in paragraph (g)(2) of this section and 
demonstrates to the satisfaction of the POTW control authority that such 
source has been eliminated.
    (5) The concentration limits specified in paragraph (g)(2) of this 
section apply at the point of discharge from the tube reducing process. 
However, sampling

[[Page 626]]

after the tube reducing wastewater has been commingled with other 
wastewaters is permitted if:
    (i) Any dilution caused by the other wastewaters is taken into 
account in determining the appropriate (i.e., lower) allowable discharge 
concentration; and
    (ii) An analytical method of sufficient sensitivity is used to 
measure the levels of each of the foregoing nitrosamine compounds in the 
wastewaters being sampled.
    (h) Surface treatment spent baths.
