                               EXPLANATION

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

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

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

LEGAL STATUS

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

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, July 1, 2023), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

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

OMB CONTROL NUMBERS

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

[[Page vi]]

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

PAST PROVISIONS OF THE CODE

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

``[RESERVED]'' TERMINOLOGY

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

INCORPORATION BY REFERENCE

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

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Authorities 
and Rules. A list of CFR titles, chapters, subchapters, and parts and an 
alphabetical list of agencies publishing in the CFR are also included in 
this volume.
    An index to the text of ``Title 3--The President'' is carried within 
that volume.

[[Page vii]]

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

REPUBLICATION OF MATERIAL

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

425.30).

[53 FR 9181, Mar. 21, 1988]



Sec.  425.04  Applicability of sulfide pretreatment standards.

    (a) A POTW receiving wastewater from a facility subject to this part 
may require more stringent pretreatment standards for sulfide than those 
established by this part without EPA approval.

[[Page 8]]

    (b) The pretreatment standards for sulfide established by this part 
will not apply if the POTW receiving wastewater from a facility subject 
to this part certifies in writing with explanation of relevant factors 
considered, in accordance with the provisions of paragraph (c) of this 
section, that the discharge of sulfide from the facility does not 
interfere with the operation of the POTW. In making this determination, 
the POTW shall consider all relevant factors including but not limited 
to the following:
    (1) The presence and characteristics, of other industrial 
wastewaters which can increase or decrease sulfide concentrations, pH, 
or both.
    (2) The characteristics of the sewer/interceptor collection system 
which either minimize or enhance opportunities for release of hydrogen 
sulfide gas.
    (3) The characteristics of the receiving POTWs headworks, 
preliminary and primary treatment systems, and sludge holding and 
dewatering facilities which either minimize or enhance opportunities for 
release of hydrogen sulfide gas.
    (4) The occurrence of any prior sulfide related interference as 
defined in Sec.  425.02(j).
    (c)(1) On October 13, 1983, a POTW which intends to certify that the 
sulfide pretreatment standard should not apply must publish, in a local 
newspaper with the largest circulation, a notice that presents the 
findings supporting this determination consistent with paragraph (a) of 
this section. Allowance for public hearing of these findings also must 
be provided. The POTW shall identify all existing facilities to which 
the sulfide pretreatment standard otherwise established by this part 
would not apply.
    (2) On January 11, 1984, a POTW which intends to certify that the 
sulfide pretreatment standard should not apply must file a written 
certification with the Regional Water Management Division Director, 
Environmental Protection Agency, in the appropriate Regional Office. 
This certification shall include the findings supporting this 
determination and the results of public comments, and public hearing(s) 
if held.
    (3) On February 10, 1984, EPA shall acknowledge to the POTW receipt 
of any certification submitted under paragraphs (c) (1) and (2) of this 
section, and shall indicate to the POTW the adequacy of the submission 
based upon a review of the factors set forth in paragraph (b) of this 
section.
    (4) Within 30 days of the date of receipt of adequate submissions 
under paragraphs (c) (1), (2), and (3) of this section, EPA shall 
publish a notice in the Federal Register identifying those facilities to 
which the sulfide pretreatment standards of this part shall not apply.
    (5) A POTW may certify that the sulfide pretreatment standards of 
this part should not apply to a new source planning to discharge into 
the POTW. This certification must be submitted prior to the commencement 
of discharge, and must conform at a minimum with criteria in paragraph 
(b) of this section and the general procedures and intervals of time 
contained in paragraphs (c) (1), (2), (3), and (4) of this section.
    (d)(1) If, after EPA and the POTW have determined in accordance with 
this section that the sulfide pretreatment standards of this part are 
not applicable to specified facilities, a POTW then determines that 
there have been changed circumstances (including but not limited to 
changes in the factors specified in paragraph (b) of this section) which 
justify application of the sulfide pretreatment standards, the POTW 
shall revoke the certification submitted under paragraph (c) of this 
section. The POTW and EPA shall then adhere to the general procedures 
and time intervals contained in paragraph (c) of this section in order 
to determine whether the sulfide pretreatment standards contained in 
this part are applicable.
    (2) If pursuant to paragraph (d)(1) of this section, the sulfide 
pretreatment standards of this part are applicable to a specified 
facility, the indirect discharger shall comply with the sulfide 
pretreatment standards no later than 18 months from the date of 
publication of the Federal Register notice identifying the facility.
    (e) At any time after October 13, 1983, if a POTW determines that 
there have

[[Page 9]]

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)

  Sec. Appendix A to Part 425--Potassium Ferricyanide Titration Method

                                 Source

    The potassium ferricyanide titration method is based on method SLM 
4/2 described in ``Official Method of Analysis,'' Society of Leather 
Trades' Chemists, Fourth Revised Edition, Redbourn, Herts., England, 
1965.

                            Outline of Method

    The buffered sulfide solution is titrated with standard potassium 
ferricyanide solution in the presence of a ferrous dimethylglyoxime 
ammonia complex. The sulfide is oxidized to sulfur. Sulfite interferes 
and must be precipitated with barium chloride. Thiosulfate is not 
titrated under the conditions of the determination (Charlot, ``Ann. 
chim, anal,'', 1945, 27, 153; Booth; ``J. Soc. Leather Trades' 
Chemists,'' 1956, 40, 238).

                                Apparatus

    Burrette, 10 ml.

                                Reagents

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

[[Page 20]]

6.6 g. of analytical reagent grade potassium ferricyanide and dissolve 
in 1 liter distilled water. Store in an amber bottle in the dark. 
Prepare fresh each week.
    2. Standardization of ferricyanide solution: Transfer 50 ml. of 
solution to a 250 ml. Erlenmeyer flask. Add several crystals of 
potassium iodide (about 1 g.), mix gently to dissolve, add 1 ml. of 6N 
hydrochloric acid, stopper the flask, and swirl gently. Let stand for 
two minutes, add 10 ml. of a 30 percent zinc sulfate solution, and 
titrate the mixture containing the gelatinous precipitate with 
standardized sodium thiosulfate or phenylarsine oxide titrant in the 
range of 0.025-0.050N Add 1 ml. of starch indicator solution after the 
color has faded to a pale yellow, and continue the titration to the 
disappearance of the blue color. Calculate the normality of the 
ferricyanide solution using the equation:
[GRAPHIC] [TIFF OMITTED] TR25SE06.000

    3. Preparation of 6M ammonium chloride buffer, pH 9.3: Dissolve 200 
g. ammonium chloride in approximately 500 ml. distilled water, add 200 
ml. 14M reagent grade ammonium hydroxide and make up to 1 liter with 
distilled water. The buffer should be prepared in a hood. Store in a 
tightly stoppered container.
    4. Preparation of 0.05M barium chloride solution: Dissolve 12-13 g. 
barium chloride dihydrate in 1 liter of distilled water.
    5. Preparation of ferrous dimethylglyoxime indicator solution: Mix 
10 ml. 0.6 percent ferrous sulfate, 50 ml. 1 percent dimethylglyoxime in 
ethanol, and 0.5 ml. concentrated sulfuric acid.
    6. Preparation of stock sulfide standard, 1000 ppm: Dissolve 2.4 g. 
reagent grade sodium sulfide in 1 liter of distilled water. Store in a 
tightly stoppered container. Diluted working standards must be prepared 
fresh daily and their concentrations determined by EPA test procedure 
376.1 (see 40 CFR 136.3, Table IB, parameter 66 (49 FR 43234, October 
26, 1984, with correction notice at 50 FR 690, January 4, 1985)) 
immediately prior to use.
    7. Preparation of 10N NaOH: Dissolve 400 g. of analytical reagent 
grade NaOH in 1 liter distilled water.

                     Sample Preservation and Storage

    Samples are to be field filtered (gravity or pressure) with coarse 
filter paper (Whatman 4 or equivalent) immediately after collection. 
Filtered samples must be preserved by adjustment to pH12 with 
10N NaOH. Sample containers must be covered tightly and stored at 4 
[deg]C until analysis. Samples must be analyzed within 48 hours of 
collection. If these procedures cannot be achieved, it is the 
laboratory's responsibility to institute quality control procedures that 
will provide documentation of sample integrity.

                                Procedure

    1. Transfer 100 ml. of sample to be analyzed, or a suitable portion 
containing not more than 15 mg. sulfide supplemented to 100 ml. with 
distilled water, to a 250 ml. Erlenmeyer flask.
    2. Adjust the sample to pH 8.5-9.5 with 6N HC1.
    3. Add 20 ml. of 6M ammonium chloride buffer (pH 9.3), 1 ml. of 
ferrous dimethylglyoxime indicator, and 25 ml. of 0.05M barium chloride. 
Mix gently, stopper, and let stand for 10 minutes.
    4. After 10 minutes titrate with standardized potassium ferricyanide 
to disappearance of pink color. The endpoint is reached when there is no 
reappearance of the pink color after 30 seconds.

                  Calculation and Reporting of Results.
[GRAPHIC] [TIFF OMITTED] TR25SE06.007

where A = volume in ml. of potassium ferricyanide solution used,
and B = normality of potassium ferricyanide solution.

    2. Report results to two significant figures.

                             Quality Control

    1. Each laboratory that uses this method is required to operate a 
formal quality control program. The minimum requirements of this program 
consist of an initial demonstration of laboratory capability and the 
analysis of replicate and spiked samples as a continuing check on 
performance. The laboratory is required to maintain performance records 
to define the quality of data that is generated. Ongoing performance 
checks must be compared with established performance criteria to 
determine if the results of analyses are within precision and accuracy 
limits expected of the method.
    2. Before performing any analyses, the analyst must demonstrate the 
ability to generate acceptable precision and accuracy with this method 
by performing the following operations.
    (a) Perform four replicate analyses of a 20 mg./l. sulfide standard 
prepared in distilled water (see paragraph 6 under ``Reagents'' above).
    (b)(1) Calculate clean water precision and accuracy in accordance 
with standard statistical procedures. Clean water acceptance limits are 
presented in paragraph 2(b)(2) below. These criteria must be met or 
exceeded before sample analyses can be initiated. A clean water standard 
must be analyzed with each sample set and the established criteria met 
for the analysis to be considered under control.
    (2) Clean water precision and accuracy acceptance limits: For 
distilled water samples containing from 5 mg./l. to 50 mg./l. sulfide, 
the mean concentration from four replicate analyses must be within the 
range of 50 to 110 percent of the true value.
    3. The Method Detection Limits (MDL) should be determined 
periodically by each participating laboratory in accordance with the 
procedures specified in ``Methods for Chemical Analysis of Municipal and 
Industrial Wastewater,'' EPA-660/4-82-057, July 1982, EMSL, Cincinnati, 
OH 45268. For the convenience of the user, these procedures are 
contained in appendix C to part 425.
    4. A minimum of one spiked and one duplicate sample must be 
performed for each analytical event, or five percent spikes and five 
percent duplicates when the number of samples per event exceeds twenty. 
Spike levels are to be at the MDL (see paragraph 3 above for MDL 
samples) and at x where x is the concentration found if in excess of the 
MDL. Spike recovery must be 40 to 120 percent for the analysis of a 
particular matrix type to be considered valid. If a sample or matrix 
type provides performance outside these acceptance limits, the analyses 
must be repeated using the modified Monier-Williams procedures described 
in appendix B to this part.
    5. Report results in mg./liter. When duplicate and spiked samples 
are analyzed, report all data with the sample results.

[53 FR 9183, Mar. 21, 1988]



      Sec. 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,

    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.

    7. Alkaline 3% hydrogen peroxide: Dilute 1 volume of 30 percent 
hydrogen peroxide with

[[Page 23]]

9 volumes of 0.03N NaOH. Prepare this solution fresh each day of use.
    8. Preparation of stock sulfide standard, 1000 ppm.: Dissolve 2.4 g. 
reagent grade sodium sulfide in 1 liter of distilled water. Store in a 
tightly stoppered container. Diluted working standards must be prepared 
fresh daily and their concentrations determined by EPA test procedure 
376.1 immediately prior to use (see 40 CFR 136.3, Table IB, parameter 66 
(49 FR 43234, October 26, 1984, and correction notice at 50 FR 690, 
January 4, 1985)).

                     Sample Preservation and Storage

    Preserve unfiltered wastewater samples immediately after collection 
by adjustment to pH9 with 6N NaOH and addition of 2 ml. of 2N 
zinc acetate per liter. This amount of zinc acetate is adequate to 
preserve 64 mg./l. sulfide under ideal conditions. Sample containers 
must be covered tightly and stored at 4 [deg]C until analysis. Samples 
must be analyzed within seven days of collection. If these procedures 
cannot be achieved, it is the laboratory's responsibility to institute 
quality control procedures that will provide documentation of sample 
integrity.

             Procedure (See Figure 1 for apparatus layout.)

    1. Place 50 ml. of 0.05M pH 7.0 potassium phosphate buffer in Trap 
No. 1.
    2. Place 50 ml. of alkaline 3 percent hydrogen peroxide in Trap No. 
2.
    3. Sample introduction and N2 prepurge: Gently mix sample 
to be analyzed to resuspend settled material, taking care not to aerate 
the sample. Transfer 400 ml. of sample, or a suitable portion containing 
not more than 20 mg. sulfide diluted to 400 ml. with distilled water, to 
the distillation flask. Adjust the N2 flow so that the 
impingers are frothing vigorously, but not overflowing. Vaccum may be 
applied at the outlet of Trap No. 2 to assist in smooth purging. The 
N2 inlet tube of the distillation flask must be submerged 
deeply in the sample to ensure efficient agitation. Purge the sample for 
30 minutes without applying heat. Test the apparatus for leaks during 
the prepurge cycle (Snoop or soap water solution).
    4. Volatilization of H2 S: Interrupt the N2 
flow (and vacuum) and introduce 100 ml. of 6N HCl to the sample using 
the separatory funnel. Immediately resume the gas flow (and vacuum). 
Apply maximum heat with the heating mantle until the sample begins to 
boil, then reduce heat and maintain gentle boiling and N2 
flow for 30 minutes. Terminate the distillation cycle by turning off the 
heating mantle and maintaining N2 flow through the system for 
5 to 10 minutes. Then turn off the N2 flow (and release 
vacuum) and cautiously vent the system by placing 50 to 100 ml. of 
distilled water in the separatory funnel and opening the stopcock 
carefully. When the bubbling stops and the system is equalized to 
atmospheric pressure, remove the separatory funnel. Extreme care must be 
exercised in terminating the distillation cycle to avoid flash-over, 
draw-back, or violent steam release.
    5. Analysis: Analyze the contents of Trap No. 2 for sulfate 
according to either EPA gravimetric test procedure 375.3 or EPA 
turbidimetric test procedure 375.4 (see 40 CFR 136.3, Table IB, 
parameter 65 (49 FR 43234, October 26, 1984, and correction notice at 50 
FR 690, January 4, 1985)). Use the result to calculate mg./l. of sulfide 
in wastewater sample.

where A = mg./l. of sulfate in Trap No. 2
B = liquid volume in liters in Trap No. 2
and C = volume in ml. of waste sample distilled

    3. Report results to two significant figures.

                             Quality Control

    1. Each laboratory that uses this method is required to operate a 
formal quality control program. The minimum requirements of this program 
consist of an initial demonstration of laboratory capability and the 
analysis of replicate and spiked samples as a continuing check on 
performance. The laboratory is required to maintain performance records 
to define the quality of data that is generated. Ongoing performance 
checks must be compared with established performance criteria to 
determine if the results of analyses are within precision and accuracy 
limits expected of the method.

[[Page 24]]

    2. Before performing any analyses, the analyst must demonstrate the 
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.

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

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

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

                          Scope and Application

    This procedure is designed for applicability to a wide variety of 
sample types ranging from reagent (blank) water containing analyte to 
wastewater containing analyte. The MDL for an analytical procedure may 
vary as a function of sample type. The procedure requires a complete, 
specific and well defined analytical method. It is essential that all 
sample processing steps of the analytical method be included in the 
determination of the method detection limit.
    The MDL obtained by this procedure is used to judge the significance 
of a single measurement of a future sample.
    The MDL procedure was designed for applicability to a broad variety 
of physical and chemical methods. To accomplish this, the procedure was 
made device- or instrument-independent.

                                Procedure

    1. Make an estimate of the detection limit using one of the 
following:
    (a) The concentration value that corresponds to an instrument 
signal/noise ratio in the range of 2.5 to 5. If the criteria for 
qualitative identification of the analyte is based upon pattern 
recognition techniques, the least abundant signal necessary to achieve 
identification must be considered in making the estimate.
    (b) The concentration value that corresponds to three times the 
standard deviation of replicate instrumental measurements for the 
analyte in reagent water.
    (c) The concentration value that corresponds to the region of the 
standard curve where there is a significant change in sensitivity at low 
analyte concentrations, i.e., a break in the slope of the standard 
curve.
    (d) The concentration value that corresponds to known instrumental 
limitations.
    It is recognized that the experience of the analyst is important to 
this process. However, the analyst must include the above considerations 
in the estimate of the detection limit.
    2. Prepare reagent (blank) water that is as free of analyte as 
possible. Reagent or interference free water is defined as a water 
sample in which analyte and interferent concentrations are not detected 
at the method detection limit of each analyte of interest. Interferences 
are defined as systematic errors in the measured analytical signal of an 
established procedure caused by the presence of interfering species 
(interferent). The interferent concentration is presupposed to be 
normally distributed in representative samples of a given matrix.
    3. (a) If the MDL is to be determined in reagent water (blank), 
prepare a laboratory

[[Page 25]]

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 (S\2\) and standard deviation (S) of the 
replicate measurements, as follows:


where: the xi, i = 1 to n are the analytical results in the 
          final method reporting units obtained from the n sample 
          aliquots and
          
          
refers to the sum of the X values from i = 1 to n.
    6. (a) Compute the MDL as follows:

MDL = t(n-1,1-a = .99) (S)

where:

MDL = the method detection
\t\ (n-1, 1-a = .99) = the students' t value appropriate for a 99 
          percent confidence level and a standard deviation estimate 
          with n-1 degrees of freedom. See Table.
S = standard deviation of the replicate analyses.
    (b) The 95 percent confidence limits for the MDL derived in 6a are 
computed according to the following equations derived from percentiles 
of the chi square over degrees of freedom distribution (X2/df) and 
calculated as follows:

MDLLCL = 0.69 MDL
MDLUCL = 1.92 MDL where MDLLCL and 
          MDLUCL are the lower and upper 95 percent 
          confidence limits respectively based on seven aliquots.

    7. Optional iterative procedure to verify the reasonableness of the 
estimated MDL and calculated MDL of subsequent MDL determinations.
    (a) If this is the initial attempt to compute MDL based on the 
estimated MDL in Step 1, take the MDL as calculated in Step 6, spike in 
the matrix at the calculated MDL and proceed through the procedure 
starting with Step 4.
    (b) If the current MDL determination is an iteration of the MDL 
procedure for which the spiking level does not permit qualitative 
identification, report the MDL as that concentration between the current 
spike level

[[Page 26]]

and the previous spike level which allows qualitative identification.
    (c) If the current MDL determination is an iteration of the MDL 
procedure and the spiking level allows qualitative identification, use 
S\2\ from the current MDL calculation and S\2\ from the previous MDL 
calculation to compute the F ratio.


then compute the pooled standard deviation by the following equation:




respike at the last calculated MDL and process the samples through the 
procedure starting with Step 4.
    (d) Use the Spooled as calculated in 7b to compute the 
final MDL according to the following equation:

MDL = 2.681 (Spooled)
where 2.681 is equal to \t\ (12, 1 -a = .99)
    (e) The 95 percent confidence limits for MDL derived in 7c are 
computed according to the following equations derived from percentiles 
of the chi squared over degrees of freedom distribution.

    MDLLCL = 0.72 MDL
    MDLUCL = 1.65 MDL

where LCL and UCL are the lower and upper 95 percent confidence limits 
          respectively based on 14 aliquots.

                                Reporting

    The analytical method used must be specifically identified by number 
or title and the MDL for each analyte expressed in the appropriate 
method reporting units. If the analytical method permits options which 
affect the method detection limit, these conditions must be specified 
with the MDL value. The sample matrix used to determine the MDL must 
also be identified with the MDL value. Report the mean analyte level 
with the MDL. If a laboratory standard or a sample that contained a 
known amount analyte was used for this determination, report the mean 
recovery, and indicate if the MDL determination was iterated.
    If the level of the analyte in the sample matrix exceeds 10 times 
the MDL of the analyte in reagent water, do not report a value for the 
MDL.

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

Sec.  426.126  Pretreatment standards for new sources.

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

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

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

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



Sec.  430.01  General definitions.

    In addition to the definitions set forth in 40 CFR part 401 and 40 
CFR 403.3, the following definitions apply to this part:
    (a) Adsorbable organic halides (AOX). A bulk parameter that measures 
the total mass of chlorinated organic matter in water and wastewater. 
The approved method of analysis for AOX is Method 1650, which is 
available in Appendix A of this part, and online at http://
water.epa.gov/scitech/methods/cwa/index.cfm.
    (b) Annual average. The mean concentration, mass loading or 
production-normalized mass loading of a pollutant over a period of 365 
consecutive days (or such other period of time determined by the 
permitting authority to be sufficiently long to encompass expected 
variability of the concentration, mass loading, or production-normalized 
mass loading at the relevant point of measurement).
    (c) Bleach plant. All process equipment used for bleaching beginning 
with the first application of bleaching agents (e.g., chlorine, chlorine 
dioxide, ozone, sodium or calcium hypochlorite, or peroxide), each 
subsequent extraction stage, and each subsequent stage where bleaching 
agents are applied to the pulp. For mills in subpart E of this part 
producing specialty grades of pulp, the bleach plant includes process 
equipment used for the hydrolysis or extraction stages prior to the 
first application of bleaching agents. Process equipment used for oxygen 
delignification prior to the application of bleaching agents is not part 
of the bleach plant.
    (d) Bleach plant effluent. The total discharge of process 
wastewaters from the bleach plant from each physical bleach line 
operated at the mill, comprising separate acid and alkaline filtrates or 
the combination thereof.
    (e) Chemical oxygen demand (COD). A bulk parameter that measures the 
oxygen-consuming capacity of organic and inorganic matter present in 
water or wastewater. It is expressed as the amount of oxygen consumed 
from a chemical oxidant in a specific test.
    (f) Elemental chlorine-free (ECF). Any process for bleaching pulps 
in the absence of elemental chlorine and hypochlorite that uses 
exclusively chlorine dioxide as the only chlorine-containing bleaching 
agent.
    (g) End of the pipe. The point at which final mill effluent is 
discharged to waters of the United States or introduced to a POTW.
    (h) Fiber line. A series of operations employed to convert wood or 
other fibrous raw material into pulp. If the final product is bleached 
pulp, the fiber line encompasses pulping, de-knotting, brownstock 
washing, pulp screening, centrifugal cleaning, and multiple bleaching 
and washing stages.
    (i) Minimum level (ML). The level at which the analytical system 
gives recognizable signals and an acceptable calibration point. The 
following minimum levels apply to pollutants in this part:

------------------------------------------------------------------------
             Pollutant                Method          Minimum level

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

[[Page 106]]

    (2) A mill is a non-continuous discharger for the purposes of 
determining applicable effluent limitations under subpart B or E of this 
part (other than conventional limits for existing sources) if, for 
reasons other than treatment plant upset control (e.g., protecting 
receiving water quality), the mill is prohibited by the NPDES authority 
from discharging pollutants during specific periods of time or if it is 
required to release its discharge on a variable flow or pollutant 
loading rate basis.
    (l) POTW. Publicly owned treatment works as defined at 40 CFR 
403.3(o).
    (m) Process wastewater. For subparts B and E only, process 
wastewater is any water that, during manufacturing or processing, comes 
into direct contact with or results from the production or use of any 
raw material, intermediate product, finished product, byproduct, or 
waste product. For purposes of subparts B and E of this part, process 
wastewater includes boiler blowdown; wastewaters from water treatment 
and other utility operations; blowdowns from high rate (e.g., greater 
than 98 percent) recycled non-contact cooling water systems to the 
extent they are mixed and co-treated with other process wastewaters; 
wastewater, including leachates, from landfills owned by pulp and paper 
mills subject to subpart B or E of this part if the wastewater is 
commingled with wastewater from the mill's manufacturing or processing 
facility; and storm waters from the immediate process areas to the 
extent they are mixed and co-treated with other process wastewaters. For 
purposes of this part, contaminated groundwaters from on-site or off-
site groundwater remediation projects are not process wastewater.
    (n) Production. (1) For all limitations and standards specified in 
this part except those pertaining to AOX and chloroform: Production 
shall be defined as the annual off-the-machine production (including 
off-the-machine coating where applicable) divided by the number of 
operating days during that year. Paper and paperboard production shall 
be measured at the off-the-machine moisture content, except for subpart 
C of this part (as it pertains to pulp and paperboard production at 
unbleached kraft mills including linerboard or bag paper and other mixed 
products, and to pulp and paperboard production using the unbleached 
kraft neutral sulfite semi-chemical (cross recovery) process), and 
subparts F and J of this part (as they pertain to paperboard production 
from wastepaper from noncorrugating medium furnish or from corrugating 
medium furnish) where paper and paperboard production shall be measured 
in air-dry-tons (10% moisture content). Market pulp shall be measured in 
air-dry tons (10% moisture). Production shall be determined for each 
mill based upon past production practices, present trends, or committed 
growth.
    (2) For AOX and chloroform limitations and standards specified in 
subparts B and E of this part: Production shall be defined as the annual 
unbleached pulp production entering the first stage of the bleach plant 
divided by the number of operating days during that year. Unbleached 
pulp production shall be measured in air-dried-metric-tons (10% 
moisture) of brownstock pulp entering the bleach plant at the stage 
during which chlorine or chlorine-containing compounds are first applied 
to the pulp. In the case of bleach plants that use totally chlorine free 
bleaching processes, unbleached pulp production shall be measured in 
air-dried-metric tons (10% moisture) of brownstock pulp entering the 
first stage of the bleach plant from which wastewater is discharged. 
Production shall be determined for each mill based upon past production 
practices, present trends, or committed growth.
    (o) TCDD. 2,3,7,8-tetrachlorodibenzo-p-dioxin.
    (p) TCDF. 2,3,7,8-tetrachlorodibenzofuran.
    (q) Totally chlorine-free (TCF) bleaching. Pulp bleaching operations 
that are performed without the use of chlorine, sodium hypochlorite, 
calcium hypochlorite, chlorine dioxide, chlorine monoxide, or any other 
chlorine-containing compound.
    (r) Wet Barking. Wet barking operations shall be defined to include 
hydraulic barking operations and wet drum barking operations which are 
those drum barking operations that use substantial quantities of water 
in

[[Page 107]]

either water sprays in the barking drums or in a partial submersion of 
the drums in a ``tub'' of water.
    (s) TCDD. 2,3,7,8-tetrachlorodibenzo-p-dioxin. The approved method 
of analysis for TCDD is Method 1613B, which is available in Appendix A 
of this part, and online at http://water.epa.gov/scitech/methods/cwa/

analysis for TCDF is Method 1613B, which is available in Appendix A of 
this part, and online at http://water.epa.gov/scitech/methods/cwa/
index.cfm.
    (u) Chloroform. The approved methods of analysis for chloroform are 
listed in Table IC at 40 CFR 136.3.
    (v) The approved method of analysis for the following chlorinated 
phenolic compounds is Method 1653, which is available in Appendix A of 
this part, and online at http://water.epa.gov/scitech/methods/cwa/

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

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

[[Page 112]]

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

[[Page 113]]

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

[[Page 114]]

    (f) Review and certification of BMP Plan. The BMP Plan, and any 
amendments thereto, must be reviewed by the senior technical manager at 
the mill and approved and signed by the mill manager. Any person signing 
the BMP Plan or its amendments must certify to the permitting or 
pretreatment control authority under penalty of law that the BMP Plan 
(or its amendments) has been prepared in accordance with good 
engineering practices and in accordance with this regulation. The mill 
is not required to obtain approval from the permitting or pretreatment 
control authority of the BMP Plan or any amendments thereto.
    (g) Record keeping requirements. (1) Each mill subject to this 
section must maintain on its premises a complete copy of the current BMP 
Plan and the records specified in paragraph (g)(2) of this section and 
must make such BMP Plan and records available to the permitting or 
pretreatment control authority and the Regional Administrator or his or 
her designee for review upon request.
    (2) The mill must maintain the following records for 3 years from 
the date they are created:
    (i) Records tracking the repairs performed in accordance with the 
repair program described in paragraph (c)(2) of this section;
    (ii) Records of initial and refresher training conducted in 
accordance with paragraph (c)(4) of this section;
    (iii) Reports prepared in accordance with paragraph (c)(5) of this 
section; and
    (iv) Records of monitoring required by paragraphs (c)(10) and (i) of 
this section.
    (h) Establishment of wastewater treatment system influent action 
levels. (1) Each mill subject to this section must conduct a monitoring 
program, described in paragraph (h)(2) of this section, for the purpose 
of defining wastewater treatment system influent characteristics (or 
action levels), described in paragraph (h)(3) of this section, that will 
trigger requirements to initiate investigations on BMP effectiveness and 
to take corrective action.
    (2) Each mill subject to this section must employ the following 
procedures in order to develop the action levels required by paragraph 
(h) of this section:
    (i) Monitoring parameters. The mill must collect 24-hour composite 
samples and analyze the samples for a measure of organic content (e.g., 
Chemical Oxygen Demand (COD) or Total Organic Carbon (TOC)). 
Alternatively, the mill may use a measure related to spent pulping 
liquor losses measured continuously and averaged over 24 hours (e.g., 
specific conductivity or color).
    (ii) Monitoring locations. For direct dischargers, monitoring must 
be conducted at the point influent enters the wastewater treatment 
system. For indirect dischargers monitoring must be conducted at the 
point of discharge to the POTW. For the purposes of this requirement, 
the mill may select alternate monitoring point(s) in order to isolate 
possible sources of spent pulping liquor, soap, or turpentine from other 
possible sources of organic wastewaters that are tributary to the 
wastewater treatment facilities (e.g., bleach plants, paper machines and 
secondary fiber operations).
    (3) By the date prescribed in paragraph (j)(1)(iii) of this section, 
each existing discharger subject to this section must complete an 
initial six-month monitoring program using the procedures specified in 
paragraph (h)(2) of this section and must establish initial action 
levels based on the results of that program. A wastewater treatment 
influent action level is a statistically determined pollutant loading 
determined by a statistical analysis of six months of daily 
measurements. The action levels must consist of a lower action level, 
which if exceeded will trigger the investigation requirements described 
in paragraph (i) of this section, and an upper action level, which if 
exceeded will trigger the corrective action requirements described in 
paragraph (i) of this section.
    (4) By the date prescribed in paragraph (j)(1)(vi) of this section, 
each existing discharger must complete a second six-month monitoring 
program using the procedures specified in paragraph (h)(2) of this 
section and must establish revised action levels based on the results of 
that program. The initial

[[Page 115]]

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

[[Page 116]]

    (vi) Establish revised action levels required by paragraph (h)(4) of 
this section as soon as possible after fully implementing the BMPs 
specified in paragraph (c) of this section, but not later than January 
15, 2002.
    (2) New sources. Upon commencing discharge, new sources subject to 
this section must implement all of the BMPs specified in paragraph (c) 
of this section, prepare the BMP Plan required by paragraph (d) of this 
section, and certify to the permitting or pretreatment authority that 
the BMP Plan has been prepared in accordance with this regulation as 
required by paragraph (f) of this section, except that the action levels 
required by paragraph (h)(5) of this section must be established not 
later than 12 months after commencement of discharge, based on six 
months of monitoring data obtained prior to that date in accordance with 
the procedures specified in paragraph (h)(2) of this section.
    (k) The provisions of paragraphs (c) through (j) of this section do 
not apply to the bleached papergrade kraft mill, commonly known as the 
Androscoggin Mill, that is owned by International Paper and located in 
Jay, Maine. In lieu of imposing the requirements specified in those 
paragraphs, the permitting authority shall establish conditions for the 
discharge of COD and color for this mill on the basis of best 
professional judgment.

        Subpart B_Bleached Papergrade Kraft and Soda Subcategory



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

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



Sec.  430.21  Specialized definitions.

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

Sec.  430.35  New source performance standards (NSPS).

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

Sec.  430.45  New source performance standards (NSPS).

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

                Subpart E_Papergrade Sulfite Subcategory



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

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



Sec.  430.51  Specialized definitions.

    (a) Except as provided in paragraphs (b) and (c) of this section, 
the general definitions, abbreviations, and methods of analysis set 
forth in 40 CFR part 401 and Sec.  430.01 of this part apply to this 
subpart.
    (b) Sulfite cooking liquor is defined as bisulfite cooking liquor 
when the pH of the liquor is between 3.0 and 6.0 and as acid sulfite 
cooking liquor when the pH is less than 3.0.
    (c) For this subpart, the segments for the papergrade sulfite 
subcategory are defined as follows:
    (1) The calcium-, magnesium-, or sodium-based sulfite pulp segment 
consists of papergrade sulfite mills where pulp and paper are produced 
using an acidic cooking liquor of calcium, magnesium, or sodium sulfite, 
unless those mills are specialty grade sulfite mills;
    (2) The ammonium-based sulfite pulp segment consists of papergrade 
sulfite mills where pulp and paper are produced using an acidic cooking 
liquor of ammonium sulfite, unless those mills are specialty grade 
sulfite mills;
    (3) The specialty grade sulfite pulp segment consists of those 
papergrade

sulfite mills where a significant portion of production is characterized 
by pulp with a high percentage of alpha cellulose and high brightness 
sufficent to produce end products such as plastic molding compounds, 
saturating and laminating products, and photographic papers. The 
specialty grade segment also includes those mills where a major portion 
of production is 91 ISO brightness and above.



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

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

Sec.  430.75  New source performance standards (NSPS).

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

effluent reduction attainable by the application of the best conventional 
pollutant control technology (BCT).

    Except as provided in 40 CFR 125.30 through 125.32, any existing 
point source subject to this subpart shall achieve the following 
effluent limitations representing the degree of effluent reduction 
attainable by the application of the best conventional pollutant control 
technology (BCT): The limitations shall be the same as those specified 
for conventional pollutants (which are defined in 40 CFR 401.16) in 
Sec.  430.92 of this subpart for the best practicable control technology 
currently available (BPT).



Sec.  430.94  Effluent limitations representing the degree of effluent 
reduction attainable by the application of the best available technology 
economically achievable (BAT).

    Except as provided in 40 CFR 125.30 through 125.32, any existing 
point source subject to this subpart where chlorophenolic-containing 
biocides are used must achieve the following effluent limitations 
representing the degree of effluent reduction attainable by the 
application of the best available technology economically achievable 
(BAT). Non-continuous dischargers shall not be subject to the maximum 
day mass limitations in kg/kkg (lb/1000 lb) but shall be subject to

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

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



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

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

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

           Sec. Appendix A to Part 430--Methods 1650 and 1653

 Method 1650--Adsorbable Organic Halides by Adsorption and Coulometric 
                                Titration

                        1.0 Scope and Application

    1.1 This method is for determination of adsorbable organic halides 
(AOX) associated with the Clean Water Act; the Resource Conservation and 
Recovery Act; the Comprehensive Environmental Response, Compensation, 
and Liability Act; and other organic halides amenable to combustion and 
coulometric titration. The method is designed to meet the survey and 
monitoring requirements of the Environmental Protection Agency (EPA).
    1.2 The method is applicable to the determination of AOX in water 
and wastewater. This method is a combination of several existing methods 
for organic halide measurements (References 1 through 7).
    1.3 The method can be used to measure organically-bound halides 
(chlorine, bromine, iodine) present in dissolved or suspended form. 
Results are reported as organic chloride (Cl-). The detection 
limit of the method is usually dependent on interferences rather than 
instrumental limitations. A method detection limit (MDL; Reference 8) of 
6.6 [micro]g/L, and a minimum level (ML; Section 18) of 20 [micro]g/L, 
can be achieved with no interferences present.
    1.4 This method is for use by or under the supervision of analysts 
experienced in the use of a combustion/micro-coulometer. Each laboratory 
that uses this method must demonstrate the ability to generate 
acceptable results using the procedures described in Section 9.2.
    1.5 Any modification of the method beyond those expressly permitted 
(Section 9.1.2) is subject to application and approval

[[Page 208]]

of an alternate test procedure under 40 CFR 136.4 and 136.5.

                          2.0 Summary of Method

    2.1 Sample preservation: Residual chlorine that may be present is 
removed by the addition of sodium thiosulfate. Samples are adjusted to a 
pH <2 and maintained at 0 to 4 [deg]C until analysis.
    2.2 Sample analysis: Organic halide in water is determined by 
adsorption onto granular activated carbon (GAC), washing the adsorbed 
sample and GAC to remove inorganic halide, combustion of the sample and 
GAC to form the hydrogen halide, and titration of the hydrogen halide 
with a micro-coulometer, as shown in Figure 1.
    2.3 Micro-coulometer.
    2.3.1 This detector operates by maintaining a constant silver-ion 
concentration in a titration cell. An electric potential is applied to a 
solid silver electrode to produce silver ions in the cell. As hydrogen 
halide produced from the combustion of organic halide enters the cell, 
it is partitioned into an acetic acid electrolyte where it precipitates 
as silver halide. The current produced is integrated over the combustion 
period. The electric charge is proportional to the number of moles of 
halogen captured in the cell (Reference 6).
    2.3.2 The mass concentration of organic halides is reported as an 
equivalent concentration of organically bound chloride (Cl-).

                             3.0 Definitions

    3.1 Adsorbable organic halides is defined as the analyte measured by 
this method. The nature of the organo-halides and the presence of semi-
extractable material will influence the amount measured and 
interpretation of results.
    3.2 Definitions for terms used in this method are given in the 
glossary at the end of the method (Section 18).

                            4.0 Interferences

    4.1 Solvents, reagents, glassware, and other sample processing 
hardware may yield elevated readings from the micro-coulometer. All 
materials used in the analysis shall be demonstrated to be free from 
interferences under the conditions of analysis by running method blanks 
initially and with each sample batch (samples started through the 
adsorption process in a given eight-hour shift, to a maximum of 20 
samples). Specific selection of reagents and purification of solvents 
may be required.
    4.2 Glassware is cleaned by detergent washing in hot water, rinsing 
with tap water and distilled water, capping with aluminum foil, and 
baking at 450 [deg]C for at least one hour. For some glassware, 
immersion in a chromate cleaning solution prior to detergent washing may 
be required. If blanks from glassware without cleaning or with fewer 
cleaning steps show no detectable organic halide, the cleaning steps 
that do not eliminate organic halide may be omitted.
    4.3 Most often, contamination results from methylene chloride vapors 
in laboratories that perform organic extractions. Heating, ventilating, 
and air conditioning systems that are shared between the extraction 
laboratory and the laboratory in which organic halide measurements are 
performed transfer the methylene chloride vapors to the air in the 
organic halide laboratory. Exposure of the activated carbon used in the 
analysis results in contamination. Separate air handling systems, 
charcoal filters, and glove boxes can be used to minimize this exposure.
    4.4 Activated carbon.
    4.4.1 The purity of each lot of activated carbon must be verified 
before each use by measuring the adsorption capacity and the background 
level of halogen (Section 9.5). The stock of activated carbon should be 
stored in its granular form in a glass container that is capped tightly. 
Protect carbon at all times from sources of halogen vapors.
    4.4.2 Inorganic substances such as chloride, chlorite, bromide, and 
iodide will adsorb on activated carbon to an extent dependent on their 
original concentration in the aqueous solution and the volume of sample 
adsorbed. Treating the activated carbon with a solution of nitrate 
causes competitive desorption of inorganic halide species. However, if 
the inorganic halide concentration is greater than 2,000 times the 
organic halide concentration, artificially high results may be obtained.
    4.4.3 Halogenated organic compounds that are weakly adsorbed on 
activated carbon are only partially recovered from the sample. These 
include certain alcohols and acids such as chloroethanol and 
chloroacetic acid that can be removed from activated carbon by the 
nitrate wash.
    4.5 Polyethylene gloves should be worn when handling equipment 
surfaces in contact with the sample to prevent transfer of contaminants 
that may be present on the hands.

                               5.0 Safety

    5.1 The toxicity or carcinogenicity of each reagent used in this 
method has not been precisely determined; however, each chemical 
substance should be treated as a potential health hazard. Exposure to 
these substances should be reduced to the lowest possible level. The 
laboratory is responsible for maintaining a current awareness file of 
OSHA regulations regarding the safe handling of the chemicals specified 
in this method. A reference file of material safety data sheets (MSDSs) 
should be made available to all personnel involved in the chemical 
analysis. Additional information on laboratory

[[Page 209]]

safety can be found in References 9 through 11.
    5.2 This method employs strong acids. Appropriate clothing, gloves, 
and eye protection should be worn when handling these substances.
    5.3 Field samples may contain high concentrations of toxic volatile 
compounds. Sample containers should be opened in a hood and handled with 
gloves that will prevent exposure.

                       6.0 Equipment and Supplies

    Note: Brand names, suppliers, and part numbers are for illustrative

    6.4.1 Adsorption module: Dohrmann AD-2, Mitsubishi TXA-2, or 
equivalent with pressurized sample and nitrate-wash reservoirs, 
adsorption columns, column housings, gas and gas pressure regulators, 
and receiving vessels. For each sample reservoir, there are two 
adsorption columns connected in series. A small steel funnel for filling

method, organic halide units were commercially available from the 
Dohrmann Division of Rosemount Analytical, Santa Clara, California; 
Euroglas BV, Delft, the Netherlands; and Mitsubishi Chemical Industries, 
Ltd., Tokyo, Japan.
    6.5.1 Combustion system: Older systems may not have all of the 
features shown in Figure 4. These older systems may be used provided the 
performance requirements (Section 9) of this method are met.
    6.5.1.1 Combustion tube: Quartz, capable of being heated to 800 to 
1000 [deg]C and accommodating a boat sampler. The tube must contain an 
air lock for introduction of a combustion boat, connections for purge 
and combustion gas, and connection to the micro-coulometer cell.
    6.5.1.2 Tube furnace capable of controlling combustion tube in the 
range of 800 to 1000 [deg]C.
    6.5.1.3 Boat sampler: Capable of holding 35 to 45 mg of activated 
carbon and a polycarbonate filter, and fitting into the

[[Page 210]]

combustion tube (Section 6.5.1.1). Some manufacturers offer an enlarged 
boat and combustion tube for this purpose. Under a time-controlled 
sequence, the boat is first moved into an evaporation zone where water 
and other volatiles are evaporated, and then into the combustion zone 
where the carbon and all other organic material in the boat are burned 
in a flowing oxygen stream. The evolved gases are transported by a non-
reactive carrier gas to the micro-coulometer cell.
    6.5.1.4 Motor driven boat sampler: Capable of advancing the 
combustion boat into the furnace in a reproducible time sequence. A 
suggested time sequence is as follows:
    A. Establish initial gas flow rates: 160 mL/min CO2; 40 
mL/min O2.
    B. Sequence start.
    C. Hold boat in hatch for five seconds to allow integration for 
baseline subtraction.
    D. Advance boat into vaporization zone.
    E. Hold boat in vaporization zone for 110 seconds.
    F. Establish gas flow rates for combustion: 200 mL/min 
O2; 0 mL/min CO2; advance boat into pyrolysis zone 
(800 [deg]C).
    G. Hold boat in pyrolysis zone for six minutes.
    H. Return gas flow rates to initial values; retract boat into hatch 
to cool and to allow remaining HX to be swept into detector 
(approximately two minutes).
    I. Stop integration at 10 minutes after sequence start.

    Note: If the signal from the detector does not return to baseline, 
it may be necessary to extend the pyrolysis time. The sequence above may 
need to be optimized for each instrument.

    6.5.1.5 Absorber: Containing sulfuric acid to dry the gas stream 
after combustion to prevent backflush of electrolyte is highly 
recommended.
    6.5.2 Micro-coulometer system: Capable of detecting the equivalent 
of 0.2 [micro]g of Cl- at a signal-to-noise ratio of 2; 
capable of detecting the equivalent of 1 [micro]g of Cl- with 
a relative standard deviation less than 10%, and capable of accumulating 
a minimum of the equivalent of 500 [micro]g of Cl- before a 
change of electrolyte is required.
    6.5.2.1 Micro-coulometer cell: The three cell designs presently in 
use are shown in Figure 1. Cell operation is described in Section 2.
    6.5.2.2 Cell controller: Electronics capable of measuring the small 
currents generated in the cell and accumulating and displaying the 
charge produced by hydrogen halides entering the cell. A strip-chart 
recorder is desirable for display of accumulated charge.
    6.6 Miscellaneous glassware: nominal sizes are specified below; 
other sizes may be used, as necessary.
    6.6.1 Volumetric flasks: 5-, 10-, 25-, 50-, 100-, and 1000-mL.
    6.6.2 Beakers: 100-, 500-, and 1000-mL.

    6.6.4 Volumetric micro-pipets: 10-, 20-, 50-, 100-, 200-, and 500-
[micro]L with pipet control (Hamilton 0010, or equivalent).
    6.6.5 Graduated cylinders: 10-, 100-, and 1000-mL.
    6.7 Micro-syringes: 10-, 50-, and 100-[micro]L.
    6.8 Balances.
    6.8.1 Top-loading, capable of weighing 0.1 g.
    6.8.2 Analytical, capable of weighing 0.1 mg.
    6.9 pH meter.
    6.10 Wash bottles: 500- to 1000-mL, PTFE or polyethylene.
    6.11 Strip-chart recorder: suggested but not required--useful for 
determining end of integration (Section 11.4.2).

                       7.0 Reagents and Standards

    7.1 Granular activated carbon (GAC): 75 to 150 [micro]m (100 to 200 
mesh); (Dohrmann, Mitsubishi, Carbon Plus, or equivalent), with chlorine 
content less than 1 [micro]g Cl- per scoop (<25 [micro]g 
Cl- per gram), adsorption capacity greater than 1000 [micro]g 
Cl- (as 2,4,6-trichlorophenol) per scoop (<=25,000 [micro]g/
g), inorganic halide retention of less than 1 [micro]g Cl- 
per scoop in the presence of 10 mg of inorganic halide (<20 [micro]g 
Cl- per gram in the presence of 2500 mg of inorganic halide), 
and that meets the other test criteria in this method.
    7.2 Reagent water: Water in which organic halide is not detected by 
this method.
    7.2.1 Preparation: Reagent water may be generated by:
    7.2.1.1 Activated carbon: Pass tap water through a carbon bed 
(Calgon Filtrasorb-300, or equivalent).
    7.2.1.2 Water purifier: Pass tap water through a purifier (Millipore 
Super Q, or equivalent).
    7.2.2 pH adjustment: Adjust the pH of the reagent water to <2 with 
nitric acid for all reagent water used in this method, except for the 
acetic acid solution (Section 7.13).
    7.3 Nitric acid (HNO3): Concentrated, analytical grade.
    7.4 Sodium chloride (NaCl) solution (100 [micro]g/mL of 
Cl-): Dissolve 0.165g NaCl in 1000 mL reagent water. This 
solution is used for cell testing and for the inorganic halide rejection 
test.
    7.5 Ammonium chloride (NH4Cl) solution (100 [micro]g/mL 
of Cl-): Dissolve 0.1509 g NH4Cl in 1000 mL 
reagent water.
    7.6 Sulfuric acid: Reagent grade (specific gravity 1.84).
    7.7 Oxygen: 99.9% purity.
    7.8 Carbon Dioxide: 99.9% purity.
    7.9 Nitrate stock solution: In a 1000-mL volumetric flask, dissolve 
17g of NaNO3 in approximately 100 mL of reagent water, add 
1.4 mL nitric acid (Section 7.3) and dilute to the mark with reagent 
water.

[[Page 211]]

    7.10 Nitrate wash solution: Dilute 50 mL of nitrate stock solution 
(Section 7.9) to 1000 mL with reagent water.
    7.11 Sodium thiosulfate (Na2S2O3) 
solution (1 N): Weigh 79 grams of 
Na2S2O3 in a 1-L volumetric flask and 
dilute to the mark with reagent water.
    7.12 Trichlorophenol solutions.

    Note: The calibration solutions in this section employ 100-mL 
volumes. For determinations requiring a larger or smaller volume, 
increase or decrease the size of the volumetric flasks commensurately. 
For example, if a 1-L sample is to be analyzed, use 1000-mL flasks 
(Sections 7.12.3.1 and 7.12.4) and 10 times the volume of reagent water 
(Sections 7.12.3.1 and 7.12.4). The volume of stock solution added to 
the calibration solutions and precision and recovery (PAR) test solution 
remain as specified (Sections 7.12.3.2 and 7.12.4) so that the same 
amount of chloride is delivered to the coulometric cell regardless of 
the volume of the calibration and PAR solutions.

    7.12.1 Methanol: HPLC grade.
    7.12.2 Trichlorophenol stock solution (1.0 mg/mL of Cl-): 
Dissolve 0.186 g of 2,4,6-trichlorophenol in 100 mL of halide-free 
methanol.
    7.12.3 Trichlorophenol calibration solutions.
    7.12.3.1 Place approximately 90 mL of reagent water in each of five 
100-mL volumetric flasks.
    7.12.3.2 Using a calibrated micro-syringe or micro-pipets, add 2, 5, 
10, 30, and 80 [micro]L of the trichlorophenol stock solution (Section 
7.12.2) to the volumetric flasks and dilute each to the mark with 
reagent water to produce calibration solutions of 2, 5, 10, 30, and 80 
[micro]g Cl- per 100 mL of solution (20, 50, 100, 300, and 
800 [micro]g/L).
    7.12.3.3 Some instruments may have a calibration range that does not 
extend to 800 [micro]g/L (80 [micro]g of Cl-). For those 
instruments, a narrower dynamic range may be used. However, if the 
concentration of halide in a sample exceeds that range, the sample must 
be diluted to bring the concentration within the range calibrated.
    7.12.4 Trichlorophenol precision and recovery (PAR) test solution 
(10 [micro]g/L of Cl-): Partially fill a 100-mL volumetric 
flask, add 10 [micro]L of the stock solution (Section 7.12.2), and 
dilute to the mark with reagent water.
    7.13 Acetic acid solution: Containing 30 to 70% acetic acid in 
deionized water, per the instrument manufacturer's instructions.

            8.0 Sample Collection, Preservation, and Storage

    8.1 Sample preservation.
    8.1.1 Residual chlorine: If the sample is known or suspected to 
contain free chlorine, the chlorine must be reduced to eliminate 
positive interference that may result from continued chlorination 
reactions. A knowledge of the process from which the sample is collected 
may be of value in determining whether dechlorination is necessary. 
Immediately after sampling, test for residual chlorine using the 
following method or an alternative EPA method (Reference 12):
    8.1.1.1 Dissolve a few crystals of potassium iodide in the sample 
and add three to five drops of a 1% starch solution. A blue color 
indicates the presence of residual chlorine.
    8.1.1.2 If residual chlorine is found, add 1 mL of sodium 
thiosulfate solution (Section 7.11) for each 2.5 ppm of free chlorine or 
until the blue color disappears. Do not add an excess of sodium 
thiosulfate. Excess sodium thiosulfate may cause decomposition of a 
small fraction of the OX.
    8.1.2 Acidification: Adjust the pH of aqueous samples to <2 with 
nitric acid. Acidification inhibits biological activity and stabilizes 
chemical degradation, including possible dehalogenation reactions that 
may occur at high pH. Acidification is necessary to facilitate thorough 
adsorption.
    8.1.3 Refrigeration: Maintain samples at a temperature of 0 to 4 
[deg]C from time of collection until analysis.
    8.2 Collect the amount of sample necessary for analysis (Section 11) 
and all QC tests (Section 9) in an amber glass bottle of the appropriate 
size (Section 6.1.1).
    8.3 Analyze samples no less than three days nor more than six months 
after collection.

                           9.0 Quality Control

    9.1 Each laboratory that uses this method is required to operate a 
formal quality assurance program. The minimum requirements of this 
program consist of an initial demonstration of laboratory capability, an 
ongoing analysis of standards and blanks as tests of continued 
performance, and analysis of matrix spike and matrix spike duplicate 
(MS/MSD) samples to assess accuracy and precision. Laboratory 
performance is compared to established performance criteria to determine 
if the results of analyses meet the performance characteristics of the 
method.
    9.1.1 The laboratory shall make an initial demonstration of the 
ability to produce acceptable results with this method. This ability is 
demonstrated as described in Section 9.2.
    9.1.2 The laboratory is permitted to modify this method to improve 
separations or lower the costs of measurements, provided that all 
performance specifications are met. Each time a modification is made to 
the method, the laboratory is required to repeat the procedures in 
Sections 9.2.2 and 10 to demonstrate continued method performance. If 
the detection limit of the method will be affected by the modification, 
the laboratory should demonstrate that the MDL (40 CFR

[[Page 212]]

136, appendix B) is less than or equal to the MDL in this method or one-
third the regulatory compliance level, whichever is higher.
    9.1.3 The laboratory shall spike 10% of the samples with known 
concentrations of 2,4,6-trichlorophenol to monitor method performance 
and matrix interferences (interferences caused by the sample matrix). 
This test is described in Section 9.3. When results of these spikes 
indicate atypical method performance for samples, the samples are 
diluted to bring method performance within acceptable limits.
    9.1.4 Analyses of blanks are required to demonstrate freedom from 
contamination. The procedures and criteria for analysis of blanks are 
described in Section 9.4.
    9.1.5 The laboratory shall, on an ongoing basis, demonstrate through 
the analysis of the precision and recovery (PAR) standard that the 
analysis system is in control. These procedures are described in Section 
9.10.
    9.1.6 The laboratory shall perform quality control tests on the 
granular activated carbon. These procedures are described in Section 
9.5.
    9.1.7 Samples are analyzed in duplicate to demonstrate precision. 
These procedures are described in Section 9.6.
    9.2 Initial demonstration of laboratory capability.
    9.2.1 Method Detection Limit (MDL): To establish the ability to 
detect AOX, the laboratory should determine the MDL per the procedure in 
40 CFR 136, appendix B using the apparatus, reagents, and standards that 
will be used in the practice of this method. An MDL less than or equal 
to the MDL in Section 1.3 should be achieved prior to the practice of 
this method.
    9.2.2 Initial precision and recovery (IPR): To establish the ability 
to generate acceptable precision and recovery, the laboratory shall 
perform the following operations:
    9.2.2.1 Analyze four aliquots of the PAR standard (Section 7.12.4) 
and a method blank according to the procedures in Sections 9.4 and 11.
    9.2.2.2 Using the blank-subtracted results of the set of four 
analyses, compute the average percent recovery (X) and the standard 
deviation of the percent recovery (s) for the results.
    9.2.2.3 The average percent recovery shall be in the range of 81 to 
114 [micro]g/L and the standard deviation shall be less than 8 [micro]g/
L. If X and s meet these acceptance criteria, system performance is 
acceptable and analysis of blanks and samples may begin. If, however, s 
exceeds the precision limit or X falls outside the range for recovery, 
system performance is unacceptable. In this case, correct the problem 
and repeat the test.
    9.3 Matrix spikes: The laboratory shall spike a minimum of 10% of 
samples from a given matrix type (e.g., C-stage filtrate, produced 
water, treated effluent) in duplicate (MS/MSD). If only one sample from 
a given matrix type is analyzed, an additional two aliquots of that 
sample shall be spiked.
    9.3.1 The concentration of the analytes spiked into the MS/MSD shall 
be determined as follows:
    9.3.1.1 If, as in compliance monitoring, the concentration of OX is 
being checked against a regulatory concentration limit, the spiking 
level shall be at that limit or at one to five times higher than the 
background concentration determined in Section 9.3.2, whichever 
concentration is higher.
    9.3.1.2 If the concentration of OX is not being checked against a 
regulatory limit, the spike shall be at the concentration of the 
precision and recovery standard (PAR; Section 7.12.4) or at one to five 
times higher than the background concentration determined in Section 
9.3.2, whichever concentration is higher.
    9.3.2 Analyze one sample out of each batch of 10 samples from each 
site to determine the background concentration of AOX. If necessary, 
prepare a solution of 2,4,6-trichlorophenol appropriate to produce a 
level in the sample one to five times the background concentration. 
Spike two additional sample aliquots with spiking solution and analyze 
them to determine the concentration after spiking.
    9.3.2.1 Compute the percent recovery of each analyte in each 
aliquot:
[GRAPHIC] [TIFF OMITTED] TR15AP98.018

    9.3.2.2 Compute the relative percent difference (RPD) between the 
two results (not between the two recoveries) as described in Section 
12.4.
    9.3.2.3 If the RPD is less than 20%, and the recoveries for the MS 
and MSD are within the range of 78 to 116%, the results are acceptable.
    9.3.2.4 If the RPD is greater than 20%, analyze two aliquots of the 
precision and recovery standard (PAR).
    9.3.2.4.1 If the RPD for the two aliquots of the PAR is greater than 
20%, the analytical system is out of control. In this case, repair the 
problem and repeat the analysis of the sample batch, including the MS/
MSD.
    9.3.2.4.2 If, however, the RPD for the two aliquots of the PAR is 
less than 20%, dilute the sample chosen for the MS/MSD by a factor of 2-
10 (to remain within the working range of the analytical system) and 
repeat the MS/MSD test. If the RPD is still greater than 20%, the result 
may not be reported for regulatory compliance purposes. In this case, 
choose another sample for the MS/MSD and repeat analysis of the sample 
batch.
    9.3.2.5 If the percent recovery for both the MS and MSD are less 
than 78% or greater

[[Page 213]]

than 116%, analyze the precision and recovery (PAR) standard.
    9.3.2.5.1 If the recovery of the PAR is outside the 78 to 116% 
range, the analytical system is out of control. In this case, repair the 
problem and repeat the analysis of the sample batch, including the MS/
MSD.
    9.3.2.5.2 If the recovery of the PAR is within the range of 78 to 
116%, dilute the sample, MS, and MSD by a factor of 2-10 (to remain 
within the working range of the analytical system) and re-analyze. If 
the results of the dilute analyses remain outside of the acceptable 
range, these results may not be reported for regulatory compliance 
purposes. In this case, choose another sample for the MS/MSD and repeat 
the analysis of the sample batch.
    9.4 Blanks.
    9.4.1 Reagent water blanks: Analyzed to demonstrate freedom from 
contamination.
    9.4.1.1 Analyze a reagent water blank with each batch of samples. 
The blank must be analyzed immediately preceding calibration 
verification to allow for blank subtraction and to demonstrate freedom 
from contamination and memory effects, and must include all details of 
the procedure to be followed when analyzing samples.
    9.4.1.2 Prepare the reagent water blank using a volume of reagent 
water equivalent to the volume used for sample preparation (Section 
11.1). If using the micro-column procedure, adsorb the method blank 
using two columns, as described in Section 11. Combust the GAC from each 
column separately, as described in Section 11.
    9.4.1.3 If the result from the blank from the batch method or the 
sum of the results from two columns is more than 20 [micro]g/L, analysis 
of samples is halted until the source of contamination is eliminated and 
a blank shows no evidence of contamination at this level.
    9.4.2 Nitrate-washed GAC blanks: Analyzed daily to demonstrate that 
the GAC is free from contamination.
    9.4.2.1 Nitrate-washed GAC blank for the batch procedure: Analyze a 
batch nitrate-washed GAC blank by adding a scoop of dry GAC to the 
assembled filter apparatus containing the polycarbonate membrane and 
washing the GAC with the nitrate wash solution (Section 7.10) using the 
procedure in Section 11.2.6.
    9.4.2.2 Nitrate-washed GAC blank for the column procedure: Analyze a 
column nitrate-washed GAC blank by assembling two carbon columns in 
series and washing the columns with the nitrate wash solution (Section 
7.10) using the procedure in Section 11.3.4.2. Analyze the GAC in each 
column separately. The results of the second analysis must be within 
0.2 [micro]g Cl- of the first. A 
difference greater than 0.2 [micro]g Cl- indicates a lack of 
homogeneity in the GAC that could introduce unacceptable variability. If 
the difference exceeds this amount, the GAC should be replaced.
    9.4.3 The result for the reagent water blank (Section 9.4.1) shall 
not exceed the result for the nitrate wash blank (Section 9.4.2.1 or 
9.4.2.2) by more than 0.5 [micro]g Cl-.
    9.5 Granular activated carbon (GAC) batch testing: Each lot number 
or batch of activated carbon received from a supplier is tested once 
before use to ensure adequate quality. Use only GAC that meets the test 
criteria below.
    9.5.1 Contamination test: Analyze a scoop of GAC. Reject carbon if 
the amount of OX exceeds 1 [micro]g (25 [micro]g Cl-/g).
    9.5.2 Inorganic chloride adsorption test: Attempt to adsorb NaCl 
from 100 mL of a solution containing 100 mg/L in reagent water. Wash 
with nitrate solution and analyze. The amount of halide should be less 
than 1 [micro]g Cl- larger than the blank. A larger amount 
indicates significant uptake of inorganic chloride by the carbon. Reject 
carbon if the 1 [micro]g level is exceeded.
    9.6 Samples that are being used for regulatory compliance purposes 
shall be analyzed in duplicate.
    9.6.1 The procedure for preparing duplicate sample aliquots is 
described in Section 11.5.
    9.6.2 Calculate the RPD by following the same procedure described in 
Section 12.4.
    9.6.3 If the RPD is greater than 20%, the analyses must be repeated.
    9.6.4 If the RPD remains greater than 20%, the result may not be 
reported for regulatory compliance purposes.
    9.7 The specifications in this method can be met if the apparatus 
used is calibrated properly and maintained in a calibrated state. The 
standards used for calibration (Section 10), calibration verification 
(Section 9.9), and for initial (Section 9.2.2) and ongoing (Section 
9.10) precision and recovery should be identical, so that the most 
precise results will be obtained.
    9.8 Depending on specific program requirements, field duplicates may 
be collected to determine the precision of the sampling technique.
    9.9 At the beginning and end of each eight-hour shift during which 
analyses are performed, system performance and calibration are verified. 
Verification of system performance and calibration may be performed more 
frequently, if desired.
    9.9.1 If performance and calibration are verified at the beginning 
and end of each shift (or more frequently), samples analyzed during that 
period are considered valid.
    9.9.2 If performance and calibration are not verified at both the 
beginning and end of a shift (or more frequently), samples analyzed 
during that period must be reanalyzed.
    9.9.3 If calibration is verified at the beginning of a shift, 
recalibration using the five standards described in Section 10.6 is not

[[Page 214]]

necessary; otherwise, the instrument must be recalibrated prior to 
analyzing samples (Section 10).
    9.9.4 Cell maintenance and other changes to the analytical system 
that can affect system performance may not be performed during the 
eight-hour (or shorter) shift.
    9.10 Calibration verification and ongoing precision and recovery: 
Calibration and system performance are verified by the analysis of the 
100 [micro]g/L PAR standard.
    9.10.1 Analyze a blank (Section 9.4) and analyze the PAR standard 
(Section 7.12.4) immediately thereafter at the beginning and end of each 
shift. Compute the concentration of organic halide in the blank and in 
the PAR standard using the procedures in Section 12. The blank shall be 
less than 2 [micro]g Cl- (20 [micro]g/L equivalent).
    9.10.2 Subtract the result for the blank from the result of the PAR 
standard using the procedures in Section 12, and compute the percent 
recovery of the blank-subtracted PAR standard. The percent recovery 
shall be in the range of 78 to 116%.
    9.10.3 If the recovery is within this range, the analytical process 
is in control and analysis of blanks and samples may proceed. If, 
however, the recovery is not within the acceptable range, the analytical 
process is not in control. In this event, correct the problem and repeat 
the ongoing precision and recovery test (Section 9.10), or recalibrate 
(Sections 10.5 through 10.6).
    9.10.4 If the recovery is not within the acceptable range for the 
PAR standard analyzed at the end of the eight-hour shift, correct the 
problem, repeat the ongoing precision and recovery test (Section 9.10), 
or recalibrate (Sections 10.5 through 10.6), and reanalyze the sample 
batch that was analyzed during the eight-hour shift.
    9.10.5 If the recovery is within the acceptable range at the end of 
the shift, and samples are to be analyzed during the next eight-hour 
shift, the end of shift verification may be used as the beginning of 
shift verification for the subsequent shift, provided the next eight-
hour shift begins as the first shift ends.
    9.11 It is suggested but not required that the laboratory develop a 
statement of data quality for AOX and develop QC charts to form a 
graphic demonstration of method performance. Add results that pass the 
specification in Section 9.10.2 to initial and previous ongoing data. 
Develop a statement of data quality by calculating the average percent 
recovery (R) and the standard deviation of percent recovery 
(sr). Express the accuracy as a recovery interval from R - 
2sr to R = 2sr. For example, if R = 95% and 
sr = 5%, the accuracy is 85 to 105%.

                  10.0 Calibration and Standardization

    10.1 Assemble the OX system and establish the operating conditions 
necessary for analysis. Differences between various makes and models of 
instruments will require different operating procedures. Laboratories 
should follow the operating instructions provided by the manufacturer of 
their particular instrument. Sensitivity, instrument detection limit, 
precision, linear range, and interference effects must be investigated 
and established for each particular instrument. Calibration is performed 
when the instrument is first set up and when calibration cannot be 
verified (Section 9.9).
    10.2 Cell performance test: Inject 100 [micro]L of the sodium 
chloride solution (10 [micro]g Cl-; Section 7.4) directly 
into the titration cell electrolyte. Adjust the instrument to produce a 
reading of 10 [micro]g Cl-.
    10.3 Combustion system test: This test can be used to assure that 
the combustion/micro-coulometer systems are performing properly without 
introduction of carbon. This test should be used during initial 
instrument setup and when instrument performance indicates a problem 
with the combustion system.
    10.3.1 Designate a quartz boat for use with the ammonium chloride 
(NH4Cl) solution only.
    10.3.2 Inject 100 [micro]L of the NH4Cl solution (Section 
7.5) into this boat and proceed with the analysis.
    10.3.3 The result shall be between 9.5 and 10.5 [micro]g 
Cl-. If the recovery is not between these limits, the 
combustion or micro-coulometer systems are not performing properly. 
Check the temperature of the combustion system, verify that there are no 
leaks in the combustion system, confirm that the cell is performing 
properly (Section 10.2), and then repeat the test.
    10.4 Trichlorophenol combustion test: This test can be used to 
assure that the combustion/micro-coulometer systems are performing 
properly when carbon is introduced. It should be used during instrument 
setup and when it is necessary to isolate the adsorption and combustion 
steps.
    10.4.1 Inject 10 [micro]L of the 1 mg/mL trichlorophenol stock 
solution (Section 7.12.2) onto one level scoop of GAC in a quartz boat.
    10.4.2 Immediately proceed with the analysis to prevent loss of 
trichlorophenol and to prevent contamination of the carbon.
    10.4.3 The result shall be between 9.0 and 11.0 [micro]g 
Cl-. If the recovery is not between these limits, the 
combustion/micro-coulometer system shall be adjusted and the test 
repeated until the result falls within these limits.
    10.5 Background level of Cl-: Determine the average 
background level of Cl- for the entire analytical system as 
follows:
    10.5.1 Using the procedure in Section 11 (batch or column) that will 
be used for the analysis of samples, determine the background level of 
Cl- in each of three portions of reagent water. The volume of 
reagent

[[Page 215]]

water used shall be the same as the volume used for analysis of samples.
    10.5.2 Calculate the average (mean) concentration of Cl- 
and the standard deviation of the concentration.
    10.5.3 The sum of the average concentration plus two times the 
standard deviation of the concentration shall be less than 20 [micro]g/
L. If not, the water or carbon shall be replaced, or the adsorption 
system moved to an area free of organic halide vapors, and the test 
(Section 10.5) shall be repeated. Only after this test is passed may 
calibration proceed.
    10.6 Calibration by external standard: A calibration line 
encompassing the calibration range is developed using solutions of 
2,4,6-trichlorophenol.
    10.6.1 Analyze each of the five calibration solutions (Section 
7.12.3) using the procedure in Section 11 (batch or column) that will be 
used for the analysis of samples, and the same procedure that was used 
for determination of the system background (Section 10.5). Analyze these 
solutions beginning with the lowest concentration and proceeding to the 
highest. Record the response of the micro-coulometer to each calibration 
solution.
    10.6.2 Prepare a method blank as described in Section 9.4. Subtract 
the value of the blank from each of the five calibration results, as 
described in Section 12.
    10.6.3 Calibration factor (ratio of response to concentration) Using 
the blank subtracted results, compute the calibration factor at each 
calibration point, and compute the average calibration factor and the 
relative standard deviation (coefficient of variation; Cv) of the 
calibration factor over the calibration range.
    10.6.4 Linearity: The Cv of the calibration factor shall be less 
than 20%; otherwise, the calibration shall be repeated after adjustment 
of the combustion/micro-coulometer system and/or preparation of fresh 
calibration standards.
    10.6.5 Using the average calibration factor, compute the percent 
recovery at each calibration point. The recovery at each calibration 
point shall be within the range of 80 to 111%. If any point is not 
within this range, a fresh calibration standard shall be prepared for 
that point, this standard shall be analyzed, and the calibration factor 
(Section 10.6.3) and calibration linearity (Section 10.6.4) shall be 
computed using the new calibration point. All points used in the 
calibration must meet the 80 to 111% recovery specification.

                             11.0 Procedure

    11.1 Sample dilution: Many samples will contain high concentrations 
of halide. If analyzed without dilution, the micro-coulometer can be 
overloaded, resulting in frequent cell cleaning and downtime. The 
following guidance is provided to assist in estimating dilution levels.
    11.1.1 Paper and pulp mills that employ chlorine bleaching: Samples 
from pulp mills that use a chlorine bleaching process may overload the 
micro-coulometer. To prevent system overload, the maximum volume 
suggested for paper industry samples that employ halide in the bleaching 
process is 100 mL. An adsorption volume as small as 25 mL may be used, 
provided the concentration of AOX in the sample can be measured 
reliably, as defined by the requirements in Section 9.11. To minimize 
volumetric error, an adsorption volume less than 25 mL may not be used. 
If AOX cannot be measured reliably in a 100-mL sample volume, a sample 
volume to a maximum of 1000 mL must be used. The sample and adsorption 
volumes are suggested for paper industry samples employing chlorine 
compounds in the bleaching process:

------------------------------------------------------------------------
* Assumes dilution to final volume of 100 mL. All sample aliquots
  (replicates, diluted samples) must be analyzed using the same fixed
  final volume (sample volume plus reagent water, as needed).

    11.1.2 Sample dilution procedure.
    11.1.2.1 Partially fill a precleaned volumetric flask with pH <2 
reagent water, allowing for the volume of sample to be added.
    11.1.2.2 Mix sample thoroughly by tumbling or shaking vigorously.
    11.1.2.3 Immediately withdraw the required sample aliquot using a 
pipet or micro-syringe.

    Note: Because it will be necessary to rinse the pipet or micro-
syringe (Section 11.1.2.5), it may be necessary to pre-calibrate the

[[Page 216]]

pipet or micro-syringe to assure that the exact volume desired will be 
delivered.

    11.1.2.4 Dispense or inject the aliquot into the volumetric flask.
    11.1.2.5 Rinse the pipet or syringe with small portions of reagent 
water and add to the flask.
    11.1.2.6 Dilute to the mark with pH <2 reagent water.
    11.1.3 All samples to be reported for regulatory compliance 
monitoring purposes must be analyzed in duplicate, as described in 
Section 11.5.
    11.1.4 Pulp and Paper in-process samples: The concentration of 
organic halide in in-process samples has been shown to be 20 to 30% 
greater using the micro-column adsorption technique than using the batch 
adsorption technique. For this reason, the micro-column technique shall 
be used for monitoring in-process samples. Examples of in-process 
samples include: combined bleach plant effluent, C-stage filtrate, and 
E-stage filtrate.
    11.2 Batch adsorption and filtration.
    11.2.1 Place the appropriate volume of sample (diluted if 
necessary), preserved as described in Section 8, into an Erlenmeyer 
flask.
    11.2.2 Add 5 mL of nitrate stock solution to the sample aliquot.
    11.2.3 Add one level scoop of activated carbon that has passed the 
quality control tests in Section 9.
    11.2.4 Shake the suspension for at least one hour in a mechanical 
shaker.
    11.2.5 Filter the suspension through a polycarbonate membrane 
filter. Filter by suction until the liquid level reaches the top of the 
carbon.
    11.2.6 Wash the inside surface of the filter funnel with 25 mL 
(5 mL) of nitrate wash solution in several 
portions. After the level of the final wash reaches the top of the GAC, 
filter by suction until the cake is barely dry. The time required for 
drying should be minimized to prevent exposure of the GAC to halogen 
vapors in the air, but should be sufficient to permit drying of the cake 
so that excess water is not introduced into the combustion apparatus. A 
drying time of approximately 10 seconds under vacuum has been shown to 
be effective for this operation.
    11.2.7 Carefully remove the top of the filter holder, making sure 
that no carbon is lost. This operation is most successfully performed by 
removing the clamp, tilting the top of the filter holder (the funnel 
portion) to one side, and lifting upward.
    11.2.8 Using a squeeze bottle or micro-syringe, rapidly rinse the 
carbon from the inside of the filter holder onto the filter cake using 
small portions of wash solution. Allow the cake to dry under vacuum for 
no more than 10 seconds after the final rinse. Immediately turn the 
vacuum off.
    11.2.9 Using tweezers, carefully fold the polycarbonate filter in 
half, then in fourths, making sure that no carbon is lost.
    11.3 Column adsorption.
    11.3.1 Column preparation: Prepare a sufficient number of columns 
for one day's operation as follows:
    11.3.1.1 In a glove box or area free from halide vapors, place a 
plug of Cerafelt into the end of a clean glass column.
    11.3.1.2 Fill the glass column with one level scoop (approximately 
40 mg) of granular activated carbon that has passed the quality control 
tests in Section 9.
    11.3.1.3 Insert a Cerafelt plug into the open end of the column to 
hold the carbon in place.
    11.3.1.4 Store the columns in a glass jar with PTFE lined screw-cap 
to prevent infiltration of halide vapors from the air.
    11.3.2 Column setup.
    11.3.2.1 Install two columns in series in the adsorption module.
    11.3.2.2 If the sample is known or expected to contain particulates 
that could prevent free flow of sample through the micro-columns, a 
Cerafelt plug is placed in the tubing ahead of the columns. If a 
measurement of the OX content of the particulates is desired, the 
Cerafelt plug can be washed with nitrate solution, placed in a 
combustion boat, and processed as a separate sample.
    11.3.3 Adjusting sample flow rate: Because the flow rate used to 
load the sample onto the columns can affect the ability of the GAC to 
adsorb organic halides, the flow rate of the method blank is measured, 
and the gas pressure used to process samples is adjusted accordingly. 
The flow rate of the blank, which is composed of acidified reagent water 
and contains no particulate matter, should be greater than the flow rate 
of any sample containing even small amounts of particulate matter.
    11.3.3.1 Fill the sample reservoir with the volume of reagent water 
chosen for the analysis (Section 9.4.1.2) that has been preserved and 
acidified as described in Section 8. Cap the reservoir.
    11.3.3.2 Adjust the gas pressure per the manufacturer's 
instructions. Record the time required for the entire volume of reagent 
water to pass through both columns. The flow rate must not exceed 3 mL/
min over the duration of the time required to adsorb the volume. If this 
flow rate is exceeded, adjust gas pressure, prepare another blank, and 
repeat the adsorption.
    11.3.3.3 Once the flow rate for the blank has been established, the 
same adsorption conditions must be applied to all subsequent samples 
during that eight-hour shift, or until another method blank is 
processed, whichever comes first. To aid in overcoming breakthrough 
problems, a lower gas pressure (and, therefore, flow rate) may be used 
for

[[Page 217]]

processing of samples, if desired. If the sample adsorption unit is 
disassembled or cleaned, the flow rate must be checked before processing 
additional samples.
    11.3.3.4 Elute the pair of columns with 2 mL of nitrate wash 
solution. The flow rate of nitrate wash solution must not exceed 3 mL/
min.
    11.3.3.5 Separate the columns and mark for subsequent analysis.
    11.3.4 The adsorption of sample volumes is performed in a similar 
fashion. Fill the sample reservoir with the sample volume chosen for the 
analysis (Section 11.1), that has been preserved as described in Section 
8. All analyses must be performed with this volume (sample volume plus 
reagent water, as needed) in order to maintain a flow rate no greater 
than that determined for the blank (see Section 11.3.3).
    11.3.4.1 Use the same gas pressure for sample adsorption as is used 
for the blank.
    11.3.4.2 Elute the columns with 2 mL of the nitrate wash solution.
    11.3.4.3 Separate the columns and mark for subsequent analysis.
    11.3.5 If it is desirable to make measurements at levels lower than 
can be achieved with the sample volume chosen, or if the instrument 
response of an undiluted sample is less than three times the instrument 
response of the blank (Section 12.6.3), a larger sample volume must be 
used.
    11.4 Combustion and titration.
    11.4.1 Polycarbonate filter and GAC from batch adsorption.
    11.4.1.1 Place the folded polycarbonate filter containing the GAC in 
a quartz combustion boat, close the airlock, and proceed with the 
automated sequence.
    11.4.1.2 Record the signal from the micro-coulometer for a minimum 
integration time of 10 minutes and determine the concentration of 
Cl- from calibration data, per Section 12.
    11.4.2 Columns from column adsorption.
    11.4.2.1 Using the push rod, push the carbon and the Cerafelt 
plug(s) from the first column into a combustion boat. Proceed with the 
automated sequence.
    11.4.2.2 Record the signal from the micro-coulometer for a minimum 
integration time of 10 minutes and determine the concentration of 
Cl- for the first column from calibration data, per Section 
12.
    11.4.2.3 Repeat the automated sequence with the second column.
    11.4.2.4 Determine the extent of breakthrough of organic halides 
from the first column to the second column, as described in Section 12.
    11.4.3 The two columns that are used for the method blank must be 
combusted separately, as is done for samples. 11.5 Duplicate sample 
analysis: All samples to be reported for regulatory compliance purposes 
must be analyzed in duplicate. This requirement applies to both the 
batch and column adsorption procedures. In addition, if it is necessary 
to dilute the sample for the purposes of reducing breakthrough or 
maintaining the concentration within the calibration range, a more or 
less dilute sample must be analyzed. The adsorption volumes used for 
analysis of undiluted samples, diluted samples, and all replicates must 
be the same as the volume used for QC tests and calibration (Sections 9 
and 10).
    11.5.1 Using results from analysis of one sample volume (Section 
11.4) and the procedure in Section 11.1.2, determine if the dilution 
used was within the calibration range of the instrument and/or if 
breakthrough exceeded the specification in Section 12.3.1. If the 
breakthrough criterion was exceeded or the sample was not within the 
calibration range, adjust the dilution volume as needed. If the 
breakthrough criterion was not exceeded and the sample dilution was 
within the calibration range, a second volume at the same dilution level 
may be used.
    11.5.2 Adsorb the sample using the same technique (batch or column) 
used for the first sample volume. Combust the GAC from the second volume 
as described in Section 11.4, and calculate the results as described in 
Section 12. Compare the results of the two analyses as described in 
Section 12.4.
    11.5.3 Duplicate analyses are not required for method blanks, as 
different dilution levels are not possible.
    11.5.4 Duplicate analyses of the PAR standard used for calibration 
verification (Section 9.10) are not required.

                   12.0 Data Analysis and Calculations

    12.1 Batch Adsorption Method: Calculate the blank-subtracted 
concentration of adsorbable organic halide detected in each sample (in 
micrograms of chloride per liter) using the following equation:
[GRAPHIC] [TIFF OMITTED] TR15AP98.019

Where:

C=[micro]g Cl- from micro-coulometer for the sample
B=[micro]g Cl- from micro-coulometer for the reagent water 
          blank (Section 9.4.1)
V = volume of sample in liters

    This calculation is performed for each of the two dilution levels 
analyzed for each sample.
    12.2 Column Adsorption Method: Calculate the blank-subtracted 
concentration of adsorbable organic halide detected in each sample (in 
micrograms of chloride per liter) using the following equation:

[[Page 218]]

[GRAPHIC] [TIFF OMITTED] TR15AP98.020


C1=[micro]g Cl- from micro-coulometer for first 
          column from the sample
C2=[micro]g Cl- from micro-coulometer for second 
          column from the sample
B1=[micro]g from micro-coulometer for first column from the 
          reagent water blank (Section 9.4.1)
B2=[micro]g Cl- from micro-coulometer for second 
          column from the reagent water blank (Section 9.4.1)
V = volume of sample in liters

    12.3 Percent breakthrough: For each sample analyzed by the column 
method, calculate the percent breakthrough of halide from the first 
column to the second column, using the following equation:
[GRAPHIC] [TIFF OMITTED] TR15AP98.021

    12.3.1 For samples to be reported for regulatory compliance 
purposes, the percent breakthrough must be less than or equal to 25% for 
both of the two analyses performed on each sample (see Section 11.5).
    12.3.2 If the breakthrough exceeds 25%, dilute the affected sample 
further, maintaining the amount of halide at least three times higher 
than the level of blank, and reanalyze the sample. Ensure that the 
sample is also analyzed at a second level of dilution that is at least a 
factor of 2 different (and still higher than three times the blank).
    12.4 Relative percent difference (RPD): Calculate the relative 
percent difference between the results of the two analyses of each 
sample, using the following equation:
[GRAPHIC] [TIFF OMITTED] TR15AP98.022

    12.5 High concentrations of AOX: If the amount of halide from either 
analysis exceeds the calibration range, dilute the sample and reanalyze, 
maintaining at least a factor of 2 difference in the dilution levels of 
the two portions of the sample used.
    12.6 Low concentrations of AOX: The blank-subtracted final result 
from the batch procedure or the sum of the blank-subtracted results from 
the two carbon columns should be significantly above the level of the 
blank.
    12.6.1 If the instrument response for a sample exceeds the 
instrument response for the blank by a factor of at least 3, the result 
is acceptable.
    12.6.2 If the instrument response for a sample is less than three 
times the instrument response for the blank, and the sample has been 
diluted, analyze a less dilute aliquot of sample.
    12.6.3 If the instrument response of an undiluted sample containing 
AOX above the minimum level is less than three times the instrument 
response for the blank, the result is suspect and may not be used for 
regulatory compliance purposes. In this case, find the cause of 
contamination, correct the problem, and reanalyze the sample under the 
corrected conditions.
    12.7 Report results that meet all of the specifications in this 
method as the mean of the blank-subtracted values from Section 12.1 or 
12.2 for the two analyses at different dilution levels, in [micro]g/L of 
Cl- (not as 2,4,6-trichlorophenol), to three significant 
figures. Report the RPD of the two analyses. For samples analyzed by the 
column procedure, also report the percent breakthrough.

                         13.0 Method Performance

    The specifications contained in this method are based on data from a 
single laboratory and from a large-scale study of the pulp and paper 
industry.

                        14.0 Pollution Prevention

    14.1 The solvents used in this method pose little threat to the 
environment when recycled and managed properly.
    14.2 Standards should be prepared in volumes consistent with 
laboratory use to minimize the volume of expired standards to be 
disposed.

                          15.0 Waste Management

    15.1 It is the laboratory's responsibility to comply with all 
federal, state, and local regulations governing waste management, 
particularly the hazardous waste identification rules and land disposal 
restrictions, and to protect the air, water, and land by minimizing and 
controlling all releases from fume hoods and bench operations. 
Compliance with all sewage discharge permits and regulations is also 
required.
    15.2 Samples preserved with HCl or H2SO4 to pH 
<2 are hazardous and must be neutralized before being disposed, or must 
be handled as hazardous waste. Acetic acid and silver acetate solutions 
resulting from cell flushing must be disposed of in accordance with all 
applicable federal, state, and local regulations.

Method 1653--Chlorinated Phenolics in Wastewater by In Situ Acetylation 
                                and GCMS

                        1.0 Scope and Application

    1.1 This method is for determination of chlorinated phenolics 
(chlorinated phenols, guaiacols, catechols, vanillins, syringaldehydes) 
and other compounds associated with the Clean Water Act; the Resource 
Conservation and Recovery Act; and the Comprehensive Environmental 
Response, Compensation, and Liability Act; and that are amenable to in 
situ acetylation, extraction, and analysis by capillary column gas 
chromatography/mass spectrometry (GCMS). This method is based on 
existing methods for determination of chlorophenolics in pulp and paper 
industry wastewaters (References 1 and 2).
    1.2 The chemical compounds listed in Table 1 may be determined in 
waters and, specifically, in in-process streams and

[[Page 225]]

wastewaters associated with the pulp and paper industry. The method is 
designed to meet the survey and monitoring requirements of the 
Environmental Protection Agency (EPA).
    1.3 The detection limit of this method is usually dependent on the 
level of interferences rather than instrumental limitations. The method 
detection limits (MDLs) in Table 2 typify the minimum quantity that can 
be detected with no interferences present.
    1.4 The GCMS portions of this method are for use only by persons 
experienced with GCMS or under the close supervision of such qualified 
persons. Laboratories unfamiliar with analyses of environmental samples 
by GCMS should run the performance tests in Reference 3 before 
beginning.
    1.5 Any modification of the method beyond those expressly permitted 
is subject to the application and approval of alternative test 
procedures under 40 CFR parts 136.4 and 136.5.

                          2.0 Summary of Method

    2.1 A 1000-mL aliquot of water is spiked with stable isotopically 
labeled analogs of the compounds of interest and an internal standard. 
The solution is adjusted to neutral pH, potassium carbonate buffer is 
added, and the pH is raised to 9-11.5. The chlorophenolics are converted 
in situ to acetates by the addition of acetic anhydride. After 
acetylation, the solution is extracted with hexane. The hexane is 
concentrated to a final volume of 0.5 mL, an instrument internal 
standard is added, and an aliquot of the concentrated extract is 
injected into the gas chromatograph (GC). The compounds are separated by 
GC and detected by a mass spectrometer (MS). The labeled compounds and 
internal standard serve to correct the variability of the analytical 
technique.
    2.2 Identification of a pollutant (qualitative analysis) is 
performed by comparing the relative retention time and mass spectrum to 
that of an authentic standard. A compound is identified when its 
relative retention time and mass spectrum agree.
    2.3 Quantitative analysis is performed in one of two ways by GCMS 
using extracted ion-current profile (EICP) areas: (1) For those 
compounds listed in Table 1 for which standards and labeled analogs are 
available, the GCMS system is calibrated and the compound concentration 
is determined using an isotope dilution technique; (2) for those 
compounds listed in Table 1 for which authentic standards but no labeled 
compounds are available, the GCMS system is calibrated and the compound 
concentration is determined using an internal standard technique.
    2.4 Quality is assured through reproducible calibration and testing 
of the extraction and GCMS systems.

                             3.0 Definitions

    3.1 Chlorinated phenolics are the chlorinated phenols, guaiacols, 
catechols, vanillins, syringaldehydes and other compounds amenable to in 
situ acetylation, extraction, and determination by GCMS using this 
method.
    3.2 Definitions for other terms used in this method are given in the 
glossary at the end of the method (Section 20.0).

                            4.0 Interferences

    4.1 Solvents, reagents, glassware, and other sample processing 
hardware may yield artifacts and/or elevated baselines, causing 
misinterpretation of chromatograms and spectra. All materials used in 
the analysis shall be demonstrated to be free from interferences under 
the conditions of analysis by running method blanks initially and with 
each sample batch (samples started through the extraction process on a 
given eight-hour shift, to a maximum of 20). Specific selection of 
reagents and purification of solvents by distillation in all-glass 
systems may be required. Glassware and, where possible, reagents are 
cleaned by using solvent rinse and baking at 450 [deg]C for a minimum of 
one hour.
    4.2 Interferences co-extracted from samples will vary considerably 
from source to source, depending on the diversity of the site being 
sampled. Industry experience suggests that high levels of non-
chlorinated phenols may cause poor recovery of the compounds of 
interest, particularly in samples collected in the vicinity of a source 
of creosote, such as a wood-preserving plant (Reference 1).
    4.3 The internal standard, 3,4,5-trichlorophenol, has been reported 
to be an anaerobic degradation product of 2,3,4,5-tetrachlorophenol and/
or pentachlorophenol (Reference 1). When an interference with this or 
another compound occurs, labeled pentachlorophenol or another labeled 
compound may be used as an alternative internal standard; otherwise, the 
internal standards and reference compounds must be used as specified in 
this method.
    4.4 Blank contamination by pentachlorophenol has been reported 
(Reference 1) to be traceable to potassium carbonate; it has also been 
reported that this contamination may be removed by baking overnight at 
400 to 500 [deg]C.
    4.5 Catechols are susceptible to degradation by active sites on 
injection port liners and columns, and are subject to oxidation to the 
corresponding chloro-o-benzoquinones (Reference 2). A small amount of 
ascorbic acid may be added to samples to prevent auto-oxidation 
(Reference 2; also see Section 11.1.6). For pulp and paper industry 
samples, ascorbic acid may be added to treated effluent samples only.

                               5.0 Safety

    5.1 The toxicity or carcinogenicity of each compound or reagent used 
in this method has not been precisely determined; however, each chemical 
compound should be treated as a potential health hazard. Exposure to 
these compounds should be reduced to the lowest possible level. The 
laboratory is responsible for maintaining a current awareness file of 
OSHA regulations regarding the safe handling of the chemicals specified 
in this method. A reference file of materials safety data sheets (MSDSs) 
should be made available to all personnel involved in these analyses. 
Additional information on laboratory safety can be found in References 4 
through 6.
    5.2 Samples may contain high concentrations of toxic compounds, and 
should be handled with gloves and a hood opened to prevent exposure.

                       6.0 Equipment and Supplies

    Note: Brand names, suppliers, and part numbers are for illustrative 
purposes only. No endorsement is implied. Equivalent performance may be 
achieved using apparatus and materials other than those specified here, 
but demonstration of equivalent performance that meets the requirements 
of this method is the responsibility of the laboratory.

                       7.0 Reagents and Standards

    7.1 Reagents for adjusting sample pH.
    7.1.1 Sodium hydroxide: Reagent grade, 6 N in reagent water.
    7.1.2 Sulfuric acid: Reagent grade, 6 N in reagent water.
    7.2 Reagents for sample preservation.
    7.2.1 Sodium thiosulfate (Na2S2O3) 
solution (1 N): Weigh 79 g Na2S2O3 in a 
1-L volumetric flask and dilute to the mark with reagent water.
    7.2.2 Ascorbic acid solution: Prepare a solution of ascorbic acid in 
reagent water at a concentration of 0.1 g/mL. This solution must be 
prepared fresh on each day when derivatizations will be performed. 
Therefore, do not prepare more than will be used that day. (A 50-mL 
volume is sufficient for ten analyses).
    7.3 Solvents: Hexane, acetone, and methanol. Distilled in glass 
(Burdick and Jackson, or equivalent).
    7.4 Reagent water: Water in which the compounds of interest and 
interfering compounds are not detected by this method.
    7.5 Reagents for derivatization.
    7.5.1 Potassium carbonate (K2CO3).
    7.5.1.1 Purification: Spread in a shallow baking dish, heat 
overnight at 400 to 500 [deg]C.
    7.5.1.2 Solution: Dissolve 150 g purified 
K2CO3 in 250 mL reagent water.
    7.5.2 Acetic anhydride: Redistilled reagent grade.
    7.6 Analytical standards.
    7.6.1 Derivatization: Because the chlorinated phenolics are 
determined as their acetate derivatives after in situ acetylation, the 
method requires that the calibration standards be prepared by spiking 
the underivatized materials into reagent water and carrying the spiked 
reagent water aliquot through the entire derivatization and extraction 
procedure that is applied to the field samples.
    7.6.2 Standard solutions: Purchased as solutions or mixtures with 
certification to their purity, concentration, and authenticity, or 
prepared from materials of known purity and composition. If chemical 
purity of a compound is 98% or greater, the weight may be used without 
correction to compute the concentration of the standard. When not being 
used, standards are stored in the dark at -20 to -10 [deg]C in screw-
capped vials with PTFE-lined lids. A mark is placed on the vial at the 
level of the solution so that solvent evaporation loss can be detected. 
The vials are brought to room temperature prior to use.
    7.6.3 If the chemical purity of any standard does not meet the 98% 
requirement above, the laboratory must correct all calculations, 
calibrations, etc., for the difference in purity.
    7.7 Preparation of stock solutions: Prepare chlorovanillins and 
chlorosyringaldehydes in acetone, as these compounds are subject to 
degradation in methanol. Prepare the remaining chlorophenolics in 
methanol. Prepare all standards per the steps below. Observe the safety 
precautions in Section 5.
    7.7.1 Dissolve an appropriate amount of assayed reference material 
in a suitable solvent. For example, weigh 50 mg (0.1 mg) of pentachlorophenol in a 10-mL ground-glass-

[[Page 228]]

stoppered volumetric flask and fill to the mark with methanol. After the 
pentachlorophenol is completely dissolved, transfer the solution to a 
15-mL vial with PTFE-lined cap.
    7.7.2 Stock solutions should be checked for signs of degradation 
prior to the preparation of calibration or performance test standards 
and shall be replaced after six months, or sooner if comparison with 
quality control check standards indicates a change in concentration.
    7.8 Labeled compound spiking solution: From stock solutions prepared 
as above, or from mixtures, prepare one spiking solution to contain the 
labeled chlorovanillin in acetone and a second spiking solution to 
contain the remaining chlorophenolics, including the 3,4,5-
trichlorophenol sample matrix internal standard (SMIS), in methanol. The 
labeled compounds and SMIS are each at a concentration of 12.5 [micro]g/
mL.
    7.9 Secondary standards for calibration: Using stock solutions 
(Section 7.7), prepare one secondary standard containing the 
chlorovanillins and chlorsyringaldehydes listed in Table 1 in acetone 
and a second secondary standard containing the remaining chlorophenolics 
in methanol. The monochlorinated phenol, guaiacol, and catechol are 
included at a concentration of 25 [micro]g/mL; the trichlorinated 
catechols, tetrachlorinated guaiacol and catechol, pentachlorophenol, 
5,6-dichlorovanillin, and 2,6-dichlorosyringaldehyde are included at a 
concentration of 100 [micro]g/mL; and the remaining compounds are 
included at a concentration of 50 [micro]g/mL, each in their respective 
solutions.
    7.10 Instrument internal standard (IIS): Prepare a solution of 2,2'-
difluorobiphenyl (DFB) at a concentration of 2.5 mg/mL in hexane.
    7.11 DFTPP solution: Prepare a solution of DFTPP at 50 [micro]g/mL 
in acetone.
    7.12 Solutions for obtaining authentic mass spectra (Section 10.2): 
Prepare mixtures of compounds at concentrations which will assure 
authentic spectra are obtained for storage in libraries.
    7.13 Preparation of calibration solutions.
    7.13.1 Into five 1000-mL aliquots of reagent water, spike 50, 100, 
200, 500 and 1000 [micro]L of each of the two solutions in Section 7.9. 
Spike 1.00 mL of each of the two labeled compound spiking solutions 
(Section 7.8) into each of the five aliquots.
    7.13.2 Using the procedure in Section 11, derivatize and extract 
each solution, and concentrate the extract to a final volume of 0.50 mL. 
This will produce calibration solutions of nominal 5, 10, 20, 50, and 
100 [micro]g/mL of the native chlorophenolics and a constant 
concentration of 25 [micro]g/mL of each labeled compound and the SMIS 
(assuming 100% derivatization and recovery). As noted in Section 11.1.6, 
ascorbic acid is added to all samples of final effluents to stabilize 
chlorocatechols, but is not added to samples of pulp and paper in-
process wastewaters. Therefore, it is necessary to prepare separate sets 
of five initial calibration standards with and without the addition of 
ascorbic acid. Also, in the event that the laboratory is extracting 
final effluent samples by both the stir-bar and separatory funnel 
procedures (see Section 11.3), initial calibration standards should be 
prepared by both methods.
    7.13.3 These solutions permit the relative response (labeled to 
unlabeled) and the response factor to be measured as a function of 
concentration (Sections 10.4 and 10.5).
    7.13.4 The nominal 50 [micro]g/mL standard may also be used as a 
calibration verification standard (see Section 9.6).
    7.14 Ongoing precision and recovery (OPR) standard: Used for 
determination of initial (Section 9.3.2) and ongoing (Section 9.6) 
precision and recovery. This solution is prepared by spiking 500 
[micro]L of each the two solutions of the secondary calibration 
standards (Section 7.9) and 1 mL of each of the two labeled compound 
spiking solutions (Section 7.8) into 1000 mL of reagent water.
    7.15 Stability of solutions: All standard solutions (Sections 7.7 
through 7.14) shall be analyzed within 48 hours of preparation and on a 
monthly basis thereafter for signs of degradation. Standards will remain 
acceptable if the peak area at the quantitation m/z relative to the DFB 
internal standard remains within 15% of the area 
obtained in the initial analysis of the standard.

            8.0 Sample Collection, Preservation, and Storage

    8.1 Collect samples in glass containers (Section 6.1) following 
conventional sampling practices (Reference 9). Aqueous samples are 
collected in refrigerated bottles using automatic sampling equipment.
    8.2 Sample preservation.
    8.2.1 Residual chlorine: If the sample contains residual chlorine, 
the chlorine must be reduced to eliminate positive interference 
resulting from continued chlorination reactions. Immediately after 
sampling, test for residual chlorine using the following method or an 
alternative EPA method (Reference 10).
    8.2.1.1 Dissolve a few crystals of potassium iodide in the sample 
and add three to five drops of a 1% starch solution. A blue color 
indicates the presence of residual chlorine.
    8.2.1.2 If residual chlorine is found, add 1 mL of sodium 
thiosulfate solution (Section 7.2.1) for each 2.5 ppm of free chlorine 
or until the blue color disappears.
    8.2.2 Acidification: Adjust pH of all aqueous samples to <2 with 
sulfuric acid (Section 7.1.2). Failure to acidify samples may result in 
positive interferences from continued chlorination reactions.

[[Page 229]]

    8.2.3 Refrigeration: Maintain sample temperature at 0 to 4 [deg]C 
from time of collection until extraction, and maintain extracts at a 
temperature of 0 to 4 [deg]C from time of extraction until analysis.
    8.3 Collect a minimum of 2000 mL of sample. This will provide a 
sufficient amount for all testing. Smaller amounts may be collected if 
the stream is known to contain high levels of chlorophenolics.
    8.4 All samples must be acetylated and extracted within 30 days of 
collection, and must be analyzed within 30 days of acetylation. If 
labeled compound recoveries for a sample do not meet the acceptance 
criteria in Table 5 and the 30-day holding time is not met, a new sample 
must be collected.

                           9.0 Quality Control

    9.1 Each laboratory that uses this method is required to operate a 
formal quality assurance program (Reference 8). The minimum requirements 
of this program consist of an initial demonstration of laboratory 
capability, analysis of samples spiked with labeled compounds to 
evaluate and document data quality, and analysis of standards and blanks 
as tests of continued performance. Laboratory performance is compared to 
established performance criteria to determine if the results of analyses 
meet the performance characteristics of the method.
    9.1.1 DFTPP spectrum validity shall be checked at the beginning of 
each eight-hour shift during which analyses are performed. This test is 
described in Section 9.2.
    9.1.2 The laboratory shall make an initial demonstration of the 
ability to generate acceptable results with this method. This ability is 
established as described in Section 9.3.
    9.1.3 The laboratory is permitted to modify this method to improve 
separations or lower the costs of measurements, provided all performance 
specifications are met. Each time a modification is made to the method, 
the laboratory is required to repeat the procedures in Sections 10.3 and 
9.3.2 to demonstrate method performance. If the detection limits for the 
analytes in this method will be affected by the modification, the 
laboratory should demonstrate that each MDL (40 CFR 136, appendix B) is 
less than or equal to the MDL in this method or one-third the regulatory 
compliance level, whichever is higher.
    9.1.4 The laboratory shall spike all samples with labeled compounds 
and the sample matrix internal standard (SMIS) to monitor method 
performance. This test is described in Section 9.4. When results of 
these spikes indicate atypical method performance for samples, the 
samples are diluted to bring method performance within acceptable limits 
(Section 13).
    9.1.5 Analyses of blanks are required to demonstrate freedom from 
contamination. The procedures and criteria for analysis of a blank are 
described in Section 9.5.
    9.1.6 The laboratory shall, on an ongoing basis, demonstrate through 
analysis of the ongoing precision and recovery standard (Section 7.14) 
that the analysis system is in control. These procedures are described 
in Section 9.6.
    9.1.7 The laboratory shall maintain records to define the quality of 
data that is generated. Development of accuracy statements is described 
in Section 9.4.4 and 9.6.3.
    9.2 DFTPP spectrum validity: Inject 1 [micro]L of the DFTPP solution 
(Section 7.11) either separately or within a few seconds of injection of 
the OPR standard (Section 9.6) analyzed at the beginning of each shift. 
The criteria in Table 3 shall be met.
    9.3 Initial demonstration of laboratory capability.
    9.3.1 Method Detection Limit (MDL): To establish the ability to 
detect the analytes in this method, the laboratory should determine the 
MDL per the procedure in 40 CFR 136, appendix B using the apparatus, 
reagents, and standards that will be used in the practice of this 
method. MDLs less than or equal to the MDLs in Table 2 should be 
achieved prior to the practice of this method.
    9.3.2 Initial precision and recovery (IPR): To establish the ability 
to demonstrate control over the analysis system and to generate 
acceptable precision and accuracy, the laboratory shall perform the 
following operations:
    9.3.2.1 Derivatize, extract, concentrate, and analyze four 1000-mL 
aliquots of the ongoing precision and recovery standard (OPR; Section 
7.14), according to the procedure in Section 11. Separate sets of IPR 
aliquots must be prepared with the addition of ascorbic acid and 
without.
    9.3.2.2 Using results of the four analyses, compute the average 
percent recovery (X) and the relative standard deviation of the recovery 
(s) for each compound, by isotope dilution for pollutants with a labeled 
analog, and by internal standard for pollutants with no labeled analog 
and for the labeled compounds and the SMIS.
    9.3.2.3 For each compound, compare s and X with the corresponding 
limits for initial precision and recovery in Table 5. If s and X for all 
compounds meet the acceptance criteria, system performance is acceptable 
and analysis of blanks and samples may begin. If, however, any 
individual s exceeds the precision limit or any individual X falls 
outside the range for recovery, system performance is unacceptable for 
that compound. In this event, correct the problem and repeat the test 
(Section 9.3.2).
    9.4 Labeled compound recovery: The laboratory shall spike all 
samples with labeled compounds and the sample matrix internal

[[Page 230]]

standard (SMIS) to assess method performance on the sample matrix.
    9.4.1 Analyze each sample according to the method beginning in 
Section 11.
    9.4.2 Compute the percent recovery (P) of the labeled compounds and 
the SMIS using the internal standard method (Section 14.3) with 2,2'-
difluorobiphenyl as the reference compound.
    9.4.3 Compare the labeled compound and SMIS recovery for each 
compound with the corresponding limits in Table 5. If the recovery of 
any compound falls outside its warning limit, method performance is 
unacceptable for that compound in that sample. Therefore, the sample is 
complex. The sample is diluted and reanalyzed per Section 13.
    9.4.4 As part of the QA program for the laboratory, it is suggested, 
but not required, that method accuracy for samples be assessed and 
records maintained. After the analysis of five samples for which the 
labeled compounds pass the tests in Section 9.4.3, compute the average 
percent recovery (P) and the standard deviation of the percent recovery 
(sp) for the labeled compounds only. Express the accuracy assessment as 
a percent recovery interval from P-2sp to P = 2sp for each matrix. For 
example, if P = 90% and sp = 10%, the accuracy interval is expressed as 
70 to 110%. Update the accuracy assessment for each compound on a 
regular basis (e.g., after each 20 to 30 new accuracy measurements).
    9.5 Blanks: Reagent water blanks are analyzed to demonstrate freedom 
from contamination.
    9.5.1 Extract and concentrate a 1000-mL reagent water blank with 
each sample batch (samples started through the extraction process on the 
same eight-hour shift, to a maximum of 20 samples). Blanks associated 
with samples to which ascorbic acid is added must be prepared with 
ascorbic acid, and blanks associated with samples to which ascorbic acid 
is not added must be prepared without ascorbic acid. Analyze the blank 
immediately after analysis of the OPR (Section 7.14) to demonstrate 
freedom from contamination.
    9.5.2 If any of the compounds of interest (Table 1) or any 
potentially interfering compound is found in an aqueous blank at greater 
than 5 [micro]g/L (assuming a response factor of one relative to the 
sample matrix internal standard for compounds not listed in Table 1), 
analysis of samples is halted until the source of contamination is 
eliminated and a blank shows no evidence of contamination at this level.
    9.6 Calibration verification and ongoing precision and recovery: At 
the beginning of each eight-hour shift during which analyses are 
performed, analytical system performance is verified for all compounds. 
Analysis of DFTPP (Section 9.2) and the nominal 50 [micro]g/mL OPR 
(Section 11.1.5) is used to verify all performance criteria. Adjustment 
and/or recalibration, per Section 10, shall be performed until all 
performance criteria are met. Only after all performance criteria are 
met may samples and blanks be analyzed.
    9.6.1 Analyze the extract of the OPR (Section 11.1.5) at the 
beginning of each eight-hour shift and prior to analysis of samples from 
the same batch. Alternatively, a separate calibration verification may 
be performed using an aliquot of the midpoint calibration standard from 
Section 7.13 (with a nominal concentration of 50 [micro]g/mL). This 
alternative may be used to check instrument performance on failure of an 
OPR, or when samples extracted with an OPR aliquot are not analyzed 
within the same eight-hour analysis shift.
    9.6.1.1 Retention times: The absolute retention time of 2,2'-
difluorobiphenyl shall be within the range of 765 to 885 seconds, and 
the relative retention times of all pollutants and labeled compounds 
shall fall within the limits given in Table 2.
    9.6.1.2 GC resolution: The valley height between 4,6-
dichloroguaiacol and 3,4-dichloroguaiacol at m/z 192 shall not exceed 
10% of the height of the taller of the two peaks.
    9.6.1.3 Multiple peaks: Each compound injected shall give a single, 
distinct GC peak.
    9.6.2 Compute the percent recovery of each pollutant (Table 1) by 
isotope dilution (Section 10.4) for those compounds that have labeled 
analogs. Compute the percent recovery of each pollutant that has no 
labeled analog by the internal standard method (Section 10.5), using the 
3,4,5-trichlorophenol (SMIS) as the internal standard. Compute the 
percent recovery of the labeled compounds and the SMIS by the internal 
standard method, using the 2,2'-difluorobiphenyl as the internal 
standard.
    9.6.2.1 For each compound, compare the recovery with the limits for 
ongoing precision and recovery in Table 5. If all compounds meet the 
acceptance criteria, system performance is acceptable and analysis of 
blanks and samples may proceed. If, however, any individual recovery 
falls outside of the range given, system performance is unacceptable for 
that compound. In this event, there may be a problem with the GCMS or 
with the derivatization/extraction/concentration systems.
    9.6.2.2 GCMS system: To determine if the failure of the OPR test 
(Section 9.6.2.1) is due to instrument drift, analyze the current 
calibration verification extract (Section 7.13.4), calculate the percent 
recoveries of all compounds, and compare with the OPR recovery limits in 
Table 5. If all compounds meet these criteria, GCMS performance/
stability is verified, and the failure of the OPR analysis is attributed 
to problems in the derivatization/extraction/concentration of the OPR. 
In this case, analysis of the sample

[[Page 231]]

extracts may proceed. However, failure of any of the recovery criteria 
in the analysis of a sample extract requires rederivatization of that 
sample (Sections 13.3.1 and 13.3.2). If, however, the performance/
stability of the GCMS is not verified by analysis of the calibration 
verification extract, the GCMS requires recalibration and all extracts 
associated with the failed OPR must be reanalyzed.
    9.6.3 Add results that pass the specifications in Section 9.6.2.1 to 
initial and previous ongoing data for each compound. Update QC charts to 
form a graphic representation of continued laboratory performance. 
Develop a statement of laboratory accuracy for each pollutant and 
labeled compound in each matrix type (reagent water, C-stage filtrate, 
E-stage filtrate, final effluent, etc.) by calculating the average 
percent recovery (R) and the standard deviation of percent recovery 
(sr). Express the accuracy as a recovery interval from R- 2sr to R = 
2sr. For example, if R = 95% and sr = 5%, the accuracy is 85 to 105%.
    9.7 The specifications contained in this method can be met if the 
apparatus used is calibrated properly, then maintained in a calibrated 
state. The standards used for calibration (Section 10) and for initial 
(Section 9.3.2) and ongoing (Section 9.6) precision and recovery should 
be identical, so that the most precise results will be obtained. The 
GCMS instrument in particular will provide the most reproducible results 
if dedicated to the settings and conditions required for the analyses of 
chlorophenolics by this method.
    9.8 Depending on specific program requirements, field replicates may 
be collected to determine the precision of the sampling technique, and 
spiked samples may be required to determine the accuracy of the analysis 
when the internal standard method is used.

                  10.0 Calibration and Standardization

    10.1 Assemble the GCMS and establish the operating conditions in 
Section 12. Analyze standards per the procedure in Section 12 to 
demonstrate that the analytical system meets the minimum levels in Table 
2, and the mass-intensity criteria in Table 3 for 50 ng DFTPP.
    10.2 Mass-spectral libraries: Detection and identification of 
compounds of interest are dependent upon spectra stored in user-created 
libraries.
    10.2.1 Obtain a mass spectrum of the acetyl derivative of each 
chlorophenolic compound (pollutant, labeled compound, and the sample 
matrix internal standard) by derivatizing and analyzing an authentic 
standard either singly or as part of a mixture in which there is no 
interference between closely eluting components. That only a single 
compound is present is determined by examination of the spectrum. 
Fragments not attributable to the compound under study indicate the 
presence of an interfering compound.
    10.2.2 Adjust the analytical conditions and scan rate (for this test 
only) to produce an undistorted spectrum at the GC peak maximum. An 
undistorted spectrum will usually be obtained if five complete spectra 
are collected across the upper half of the GC peak. Software algorithms 
designed to ``enhance'' the spectrum may eliminate distortion, but may 
also eliminate authentic m/z's or introduce other distortion.
    10.2.3 The authentic reference spectrum is obtained under DFTPP 
tuning conditions (Section 10.1 and Table 3) to normalize it to spectra 
from other instruments.
    10.2.4 The spectrum is edited by removing all peaks in the m/z 42 to 
45 range, and saving the five most intense mass spectral peaks and all 
other mass spectral peaks greater than 10% of the base peak (excluding 
the peaks in the m/z 42 to 45 range). The spectrum may be further edited 
to remove common interfering m/z's. The spectrum obtained is stored for 
reverse search and for compound confirmation. 10.3 Minimum level: 
Demonstrate that the chlorophenolics are detectable at the minimum level 
(per all criteria in Section 14). The nominal 5 [micro]g/mL calibration 
standard (Section 7.13) can be used to demonstrate this performance.
    10.4 Calibration with isotope dilution: Isotope dilution is used 
when (1) labeled compounds are available, (2) interferences do not 
preclude its use, and (3) the quantitation m/z (Table 4) extracted ion-
current profile (EICP) area for the compound is in the calibration 
range. Alternative labeled compounds and quantitation m/z's may be used 
based on availability. If any of the above conditions preclude isotope 
dilution, the internal standard calibration method (Section 10.5) is 
used.
    10.4.1 A calibration curve encompassing the concentration range is 
prepared for each compound to be determined. The relative response 
(pollutant to labeled) vs. concentration in standard solutions is 
plotted or computed using a linear regression. The example in Figure 1 
shows a calibration curve for phenol using phenol-d5 as the isotopic 
diluent. Also shown are the 10% error limits 
(dotted lines). Relative response (RR) is determined according to the 
procedures described below. A minimum of five data points are employed 
for calibration.
    10.4.2 The relative response of a pollutant to its labeled analog is 
determined from isotope ratio values computed from acquired data. Three 
isotope ratios are used in this process:

Rx = the isotope ratio measured for the pure pollutant.
Ry = the isotope ratio measured for the labeled compound.
Rm = the isotope ratio of an analytical mixture of pollutant 
          and labeled compounds.


[[Page 232]]


    The m/z's are selected such that 
RxRy. If Rm is not between 
2Ry and 0.5Rx, the method does not apply and the 
sample is analyzed by the internal standard method.

    10.4.3 Capillary columns sometimes separate the pollutant-labeled 
pair when deuterium labeled compounds are used, with the labeled 
compound eluted first (Figure 2). For this case,
[GRAPHIC] [TIFF OMITTED] TR15AP98.028

    10.4.4 When the pollutant-labeled pair is not separated (as occurs 
with carbon-13-labeled compounds), or when another labeled compound with 
interfering spectral masses overlaps the pollutant (a case which can 
occur with isomeric compounds), it is necessary to determine the 
contributions of the pollutant and labeled compound to the respective 
EICP areas. If the peaks are separated well enough to permit the data 
system or operator to remove the contributions of the compounds to each 
other, the equations in Section 10.4.3 apply. This usually occurs when 
the height of the valley between the two GC peaks at the same m/z is 
less than 70 to 90% of the height of the shorter of the two peaks. If 
significant GC and spectral overlap occur, RR is computed using the 
following equation:
[GRAPHIC] [TIFF OMITTED] TR15AP98.029

Where:

Rx is measured as shown in figure 3A,
Ry is measured as shown in figure 3B,
Rm is measured as shown in figure 3C.

    For example, Rx = 46100/4780 = 9.644; Ry = 
2650/43600 = 0.0608; Rm = 49200/48300 = 1.1019; thus, RR = 
1.114. 10.4.5 To calibrate the analytical system by isotope dilution, 
analyze a 1-[micro]L aliquot of each of the calibration standards 
(Section 7.13) using the procedure in Section 12. Compute the RR at each 
concentration.
    10.4.6 Linearity: If the ratio of relative response to concentration 
for any compound is constant (less than 20% coefficient of variation) 
over the five-point calibration range, an averaged relative response/
concentration ratio may be used for that compound; otherwise, the 
complete calibration curve for that compound shall be used over the 
five-point calibration range.
    10.5 Calibration by internal standard: The method contains two types 
of internal standards, the sample matrix internal standard (SMIS) and 
the instrument internal standard (IIS), and they are used for different 
quantitative purposes. The 3,4,5-trichlorophenol sample matrix internal 
standard (SMIS) is used for measurement of all pollutants with no 
labeled analog and when the criteria for isotope dilution (Section 10.4) 
cannot be met. The 2,2'-difluorobiphenyl instrument internal standard 
(IIS) is used for determination of the labeled compounds and the SMIS. 
The results are used for intralaboratory statistics (Sections 9.4.4 and 
9.6.3).
    10.5.1 Response factors: Calibration requires the determination of 
response factors (RF) for both the pollutants with no labeled analog and 
for the labeled compounds and the SMIS. The response factor is defined 
by the following equation:
[GRAPHIC] [TIFF OMITTED] TR15AP98.030

Where:

As = the area of the characteristic mass for the compound in 
          the daily standard.
Ais = the area of the characteristic mass for the internal 
          standard.
Cis = the concentration of the internal standard ([micro]g/
          mL).
Cs = is the concentration of the compound in the calibration 
          standard ([micro]g/mL).

    When this equation is used to determine the response factors for 
pollutant compounds without labeled analogs, use the area 
(Ais) and concentration (Cis) of 3,4,5-
trichlorophenol (SMIS) as the internal standard. When this equation is 
used to determine the response factors for the labeled

[[Page 233]]

analogs and the SMIS, use the area (Ais) and concentration 
(Cis) of 2,2'-difluorobiphenyl as the internal standard.
    10.5.2 The response factor is determined for at least five 
concentrations appropriate to the response of each compound (Section 
7.13); nominally, 5, 10, 20, 50, and 100 [micro]g/mL. The amount of SMIS 
added to each solution is the same (25 [micro]g/mL) so that 
Cis remains constant. Likewise, the concentration of IIS is 
constant in each solution. The area ratio (As/Ais) 
is plotted versus the concentration ratio (Cs/Cis) 
for each compound in the standard to produce a calibration curve.
    10.5.3 Linearity: If the response factor (RF) for any compound is 
constant (less than 35% coefficient of variation) over the five-point 
calibration range, an averaged response factor may be used for that 
compound; otherwise, the complete calibration curve for that compound 
shall be used over the five-point range.
    10.6 Combined calibration: By using calibration solutions (Section 
7.13) containing the pollutants, labeled compounds, and the internal 
standards, a single set of analyses can be used to produce calibration 
curves for the isotope dilution and internal standard methods. These 
curves are verified each shift (Section 9) by analyzing the OPR 
standard, or an optional calibration verification (VER) standard. 
Recalibration is required only if OPR criteria (Section 9.6 and Table 5) 
cannot be met.

        11.0 Sample Derivatization, Extraction, and Concentration

    The procedure described in this section uses a stir-bar in a beaker 
for the derivatization. The extraction procedures applied to samples 
depend on the type of sample being analyzed. Extraction of samples from 
in-process wastewaters is performed using a separatory funnel procedure. 
All calibrations, IPR, OPR, and blank analyses associated with in-
process wastewater samples must be performed by the separatory funnel 
procedure.
    Extraction of samples of final effluents and raw water may be 
performed using either the stir-bar procedure or the separatory funnel 
procedure. However, all calibrations, IPR, OPR, blank, and sample 
analyses must be performed using the same procedure. Both procedures are 
described below.
    11.1 Preparation of all sample types for stir-bar derivatization.
    11.1.1 Allow sample to warm to room temperature.
    11.1.2 Immediately prior to measuring, shake sample vigorously to 
insure homogeneity.
    11.1.3 Measure 1000 mL (10 mL) of sample into 
a clean 2000-mL beaker. Label the beaker with the sample number.
    11.1.4 Dilute aliquot(s).
    11.1.4.1 Complex samples: For samples that are expected to be 
difficult to derivatize, concentrate, or are expected to overload the GC 
column or mass spectrometer, measure an additional 100 mL (1 mL) into a clean 2000-mL beaker and dilute to a final 
volume of 1000-mL (50 mL) with reagent water. 
Label with the sample number and as the dilute aliquot. However, to 
ensure adequate sensitivity, a 1000-mL aliquot must always be prepared 
and analyzed.
    11.1.4.2 Pulp and paper industry samples: For in-process streams 
such as E-stage and C-stage filtrates and other in-process wastewaters, 
it may be necessary to prepare an aliquot at an additional level of 
dilution. In this case, dilute 10 mL (0.1 mL) of 
sample to 1000-mL (50 mL).
    11.1.5 QC aliquots: For a batch of samples of the same type to be 
extracted at the same time (to a maximum of 20), place two 1000-mL 
(10 mL) aliquots of reagent water in clean 2000-mL 
beakers. Label one beaker as the blank and the other as the ongoing 
precision and recovery (OPR) aliquot. Because final effluent samples are 
treated with ascorbic acid and in-process wastewater samples are not 
(see Section 11.1.6), prepare an OPR aliquot and a blank for the final 
effluent and a separate pair for the in-process samples. Treat these QC 
aliquots in the same fashion as the associated samples, adding ascorbic 
acid to the pair associated with the final effluents, and not adding 
ascorbic acid to the pair associated with the in-process samples.
    11.1.6 Ascorbic acid: Added to stabilize chlorocatechols. However, 
for pulp and paper industry in-process streams and other in-process 
wastewaters, the addition of ascorbic acid may convert chloro-o-quinones 
to catechols if these quinones are present. Separate calibration curves 
must be prepared with and without the addition of ascorbic acid (Section 
7.13.2).
    11.1.6.1 Spike 5 to 6 mL of the ascorbic acid solution (Section 
7.2.2) into each final effluent sample, and the associated calibration 
standards, IPR and OPR aliquots, and blank.
    11.1.6.2 For pulp and paper industry C-stage filtrates, E-stage 
filtrates, and untreated effluents, omit the ascorbic acid to prevent 
the conversion of chloro-o-quinones to catechols. Prepare calibration 
standards, IPR and OPR aliquots, and blanks associated with these 
samples without ascorbic acid as well.
    11.1.7 Spike 1000 [micro]L of the labeled compound spiking solution 
(Section 7.8) into the sample and QC aliquots.
    11.1.8 Spike 500 [micro]L of the nominal 50 [micro]g/mL calibration 
solution (Section 7.13.4) into the OPR aliquot.
    11.1.9 Adjust the pH of the sample aliquots to between 7.0 and 7.1. 
For calibration standards, IPR and OPR aliquots, and blanks, pH 
adjustment is not required.

    11.1.10 Equilibrate all sample and QC solutions for approximately 15 
minutes, with occasional stirring.
    11.2 Derivatization: Because derivatization must proceed rapidly, 
particularly upon the addition of the K2CO3 
buffer, it is necessary to work with one sample at a time until the 
derivatization step (Section 11.2.3) is complete.
    11.2.1 Place a beaker containing a sample or QC aliquot on the 
magnetic stirrer in a fume hood, drop a clean stirring bar into the 
beaker, and increase the speed of the stirring bar until the vortex is 
drawn to the bottom of the beaker.
    11.2.2 Measure 25 to 26 mL of K2CO3 buffer 
into a graduated cylinder or other container and 25 to 26 mL of acetic 
acid into another.
    11.2.3 Add the K2CO3 buffer to the sample or 
QC aliquot, immediately (within one to three seconds) add the acetic 
anhydride, and stir for three to five minutes to complete the 
derivatization.
    11.3 Extraction: Two procedures are described below for the 
extraction of derivatized samples. The choice of extraction procedure 
will depend on the sample type. For final effluent samples, either of 
two procedures may be utilized for extraction of derivatized samples. 
For samples of in-process wastewaters, the separatory funnel extraction 
procedure must be used.

    Note: Whichever procedure is employed, the same extraction procedure 
must be used for calibration standards, IPR aliquots, OPR aliquots, 
blanks, and the associated field samples.

    11.3.1 Stir-bar extraction of final effluents.
    11.3.1.1 Add 200 mL (20 mL) of hexane to the 
beaker and stir for three to five minutes, drawing the vortex to the 
bottom of the beaker.
    11.3.1.2 Stop the stirring and drain the hexane and a portion of the 
water into a 500-to 1000-mL separatory funnel. Allow the layers to 
separate.
    11.3.1.3 Drain the aqueous layer back into the beaker.
    11.3.1.4 The formation of emulsions can be expected in any solvent 
extraction procedure. If an emulsion forms, the laboratory must take 
steps to break the emulsion before proceeding. Mechanical means of 
breaking the emulsion include the use of a glass stirring rod, 
filtration through glass wool, and other techniques. For emulsions that 
resist these techniques, centrifugation is nearly 100% effective.
    If centrifugation is employed to break the emulsion, drain the 
organic layer into a centrifuge tube, cap the tube, and centrifuge for 
two to three minutes or until the phases separate. If the emulsion 
cannot be completely broken, collect as much of the organic phase as 
possible, and measure and record the volume of the organic phase 
collected.
    If all efforts to break the emulsion fail, including centrifugation, 
and none of the organic phase can be collected, proceed with the dilute 
aliquot (Section 11.1.4.2). However, use of the dilute aliquot will 
sacrifice the sensitivity of the method, and may not be appropriate in 
all cases.
    11.3.1.5 Drain the organic layer into a Kuderna-Danish (K-D) 
apparatus equipped with a 10-mL concentrator tube. Label the K-D 
apparatus. It may be necessary to pour the organic layer through a 
funnel containing anhydrous sodium sulfate to remove any traces of water 
from the extract.
    11.3.1.6 Repeat the extraction (Section 11.3.1.1 through 11.3.1.5) 
two more times using another 200-mL of hexane for each extraction, 
combining the extracts in the K-D apparatus.
    11.3.1.7 Proceed with concentration of the extract, as described in 
Section 11.4.
    11.3.2 Separatory funnel extraction of either final effluents or in-
process wastewaters.
    11.3.2.1 Transfer the derivatized sample or QC aliquot to a 2-L 
separatory funnel.
    11.3.2.2 Add 200 mL (20 mL) of hexane to the 
separatory funnel. Cap the funnel and extract the sample by shaking the 
funnel for two to three minutes with periodic venting.
    11.3.2.3 Allow the organic layer to separate from the water phase 
for a minimum of 10 minutes.
    11.3.2.4 Drain the lower aqueous layer into the beaker used for 
derivatization (Section 11.2), or into a second clean 2-L separatory 
funnel. Transfer the solvent to a 1000-mL K-D flask. It may be necessary 
to pour the organic layer through a funnel containing anhydrous sodium 
sulfate to remove any traces of water from the extract.
    11.3.2.5 The formation of emulsions can be expected in any solvent 
extraction procedure. If an emulsion forms, the laboratory must take 
steps to break the emulsion before proceeding. Mechanical means of 
breaking the emulsion include the use of a glass stirring rod, 
filtration through glass wool, and other techniques. For emulsions that 
resist these techniques, centrifugation may be required.
    If centrifugation is employed to break the emulsion, drain the 
organic layer into a centrifuge tube, cap the tube, and centrifuge for 
two to three minutes or until the phases separate. If the emulsion 
cannot be completely broken, collect as much of the organic phase as 
possible, and measure and record the volume of the organic phase 
collected. If all efforts to break the emulsion, including 
centrifugation, fail and none of the organic phase can be collected, 
proceed with the dilute aliquot (Section 11.1.4.2). However, use

[[Page 235]]

of the dilute aliquot will sacrifice the sensitivity of the method, and 
may not be appropriate in all cases.
    11.3.2.6 If drained into a beaker, transfer the aqueous layer to the 
2-L separatory funnel (Section 11.3.2.1). Perform a second extraction 
using another 200 mL of fresh solvent.
    11.3.2.7 Transfer the extract to the 1000-mL K-D flask in Section 
11.3.2.4.
    11.3.2.8 Perform a third extraction in the same fashion as above.
    11.3.2.9 Proceed with concentration of the extract, as described in 
Section 11.4.
    11.4 Macro concentration: Concentrate the extracts in separate 1000-
mL K-D flasks equipped with 10-mL concentrator tubes. Add one to two 
clean boiling chips to the flask and attach a three-ball macro-Snyder 
column. Prewet the column by adding approximately 1 mL of hexane through 
the top. Place the K-D apparatus in a hot water bath so that the entire 
lower rounded surface of the flask is bathed with steam. Adjust the 
vertical position of the apparatus and the water temperature as required 
to complete the concentration in 15 to 20 minutes. At the proper rate of 
distillation, the balls of the column will actively chatter but the 
chambers will not flood. When the liquid has reached an apparent volume 
of 1 mL, remove the K-D apparatus from the bath and allow the solvent to 
drain and cool for at least 10 minutes. Remove the Snyder column and 
rinse the flask and its lower joint into the concentrator tube with 1 to 
2 mL of hexane. A 5-mL syringe is recommended for this operation.
    11.5 Micro-concentration: Final concentration of the extracts may be 
accomplished using either a micro-Snyder column or nitrogen evaporation.
    11.5.1 Micro-Snyder column: Add a clean boiling chip and attach a 
two-ball micro-Snyder column to the concentrator tube. Prewet the column 
by adding approximately 0.5 mL hexane through the top. Place the 
apparatus in the hot water bath. Adjust the vertical position and the 
water temperature as required to complete the concentration in 5 to 10 
minutes. At the proper rate of distillation, the balls of the column 
will actively chatter but the chambers will not flood. When the liquid 
reaches an apparent volume of approximately 0.2 mL, remove the apparatus 
from the water bath and allow to drain and cool for at least 10 minutes. 
Remove the micro-Snyder column and rinse its lower joint into the 
concentrator tube with approximately 0.2 mL of hexane. Adjust to a final 
volume of 0.5 mL.
    11.5.2 Nitrogen evaporation: Transfer the concentrator tube to a 
nitrogen evaporation device and direct a gentle stream of clean dry 
nitrogen into the concentrator. Rinse the sides of the concentrator tube 
with small volumes of hexane, and concentrate the extract to a final 
volume of 0.5 mL.
    11.6 Spike each extract with 10 [micro]L of the 2,2'-
difluorobiphenyl IIS (Section 7.10) and transfer the concentrated 
extract to a clean screw-cap vial using hexane to rinse the concentrator 
tube. Seal the vial with a PTFE-lined lid, and mark the level on the 
vial. Label with the sample number and store in the dark at -20 to -10 
[deg]C until ready for analysis.

                           12.0 GCMS Analysis

    12.1 Establish the following operating conditions:

Carrier gas flow: Helium at 30 cm/sec at 50 [deg]C
Injector temperature: 300 [deg]C
Initial temperature: 50 [deg]C
Temperature program: 8 [deg]C/min to 270 [deg]C
Final hold: Until after 2,6-dichlorosyringaldehyde elutes

    Adjust the GC conditions to meet the requirements in Section 9.6.1.1 
and Table 2 for analyte separation and sensitivity. Once optimized, the 
same GC conditions must be used for the analysis of all standards, 
blanks, IPR and OPR aliquots, and samples.
    12.2 Bring the concentrated extract (Section 11.6) or standard 
(Sections 7.13 and 7.14) to room temperature and verify that any 
precipitate has redissolved. Verify the level on the extract (Sections 
7.13, 7.14, and 11.6) and bring to the mark with solvent if required.
    12.3 Inject a 1-[micro]L volume of the standard solution or extract 
using on-column or splitless injection. For 0.5 mL extracts, this 1-
[micro]L injection volume will contain 50 ng of the DFB internal 
standard. If an injection volume other than 1 [micro]L is used, that 
volume must contain 50 ng of DFB.
    12.4 Start the GC column temperature ramp upon injection. Start MS 
data collection after the solvent peak elutes. Stop data collection 
after the 2,6-dichlorosyringaldehyde peak elutes. Return the column to 
the initial temperature for analysis of the next sample.

                    13.0 Analysis of Complex Samples

    Some samples may contain high levels (1000 [micro]g/L) of 
the compounds of interest, interfering compounds, and/or other phenolic 
materials. Some samples will not concentrate to 0.5 mL (Section 11.5); 
others will overload the GC column and/or mass spectrometer; others may 
contain amounts of phenols that may exceed the capacity of the 
derivatizing agent.
    13.1 Analyze the dilute aliquot (Section 11.1.4) when the sample 
will not concentrate to 0.5 mL. If a dilute aliquot was not extracted, 
and the sample holding time (Section 8.4) has not been exceeded, dilute 
an aliquot of sample with reagent water, and derivatize and extract it 
(Section 11.1.4).

[[Page 236]]

Otherwise, dilute the extract (Section 14.7.3) and quantitate it by the 
internal standard method (Section 14.3).
    13.2 Recovery of the 2,2'-difluorobiphenyl instrument internal 
standard: The EICP area of the internal standard should be within a 
factor of two of the area in the OPR or VER standard (Section 9.6). If 
the absolute areas of the labeled compounds and the SMIS are within a 
factor of two of the respective areas in the OPR or VER standard, and 
the DFB internal standard area is less than one-half of its respective 
area, then internal standard loss in the extract has occurred. In this 
case, analyze the extract from the dilute aliquot (Section 11.1.4).
    13.3 Recovery of labeled compounds and the sample matrix internal 
standard (SMIS): SMIS and labeled compound recovery specifications have 
been developed for samples with and without the addition of ascorbic 
acid. Compare the recoveries to the appropriate limits in Table 5.
    13.3.1 If SMIS or labeled compound recoveries are outside the limits 
given in Table 5 and the associated OPR analysis meets the recovery 
criteria, the extract from the dilute aliquot (Section 11.1.4) is 
analyzed as in Section 14.7.
    13.3.2 If labeled compound or SMIS recovery is outside the limits 
given in Table 5 and the associated OPR analysis did not meet recovery 
criteria, a problem in the derivatization/extraction/concentration of 
the sample is indicated, and the sample must be rederivatized and 
reanalyzed.

                   14.0 Data Analysis and Calculations

    14.1 Qualitative determination: Identification is accomplished by 
comparison of data from analysis of a sample or blank with data stored 
in the mass spectral libraries. Identification of a compound is 
confirmed when the following criteria are met:
    14.1.1 The signals for m/z 43 (to indicate the presence of the 
acetyl derivative) and all characteristic m/z's stored in the spectral 
library (Section 10.2.4) shall be present and shall maximize within the 
same two consecutive scans.
    14.1.2 Either (1) the background corrected EICP areas, or (2) the 
corrected relative intensities of the mass spectral peaks at the GC peak 
maximum shall agree within a factor of two (0.5 to 2 times) for all m/
z's stored in the library.
    14.1.3 The relative retention time shall be within the window 
specified in Table 2.
    14.1.4 The m/z's present in the mass spectrum from the component in 
the sample that are not present in the reference mass spectrum shall be 
accounted for by contaminant or background ions. If the mass spectrum is 
contaminated, an experienced spectrometrist (Section 1.4) shall 
determine the presence or absence of the compound.
    14.2 Quantitative determination by isotope dilution: By adding a 
known amount of a labeled compound to every sample prior to 
derivatization and extraction, correction for recovery of the pollutant 
can be made because the pollutant and its labeled analog exhibit the 
same effects upon derivatization, extraction, concentration, and gas 
chromatography. Relative response (RR) values for sample mixtures are 
used in conjunction with calibration curves described in Section 10.4 to 
determine concentrations directly, so long as labeled compound spiking 
levels are constant. For the phenol example given in Figure 1 (Section 
10.4.1), RR would be equal to 1.114. For this RR value, the phenol 
calibration curve given in Figure 1 indicates a concentration of 27 
[micro]g/mL in the sample extract (Cex).
    14.2.1 Compute the concentration in the extract using the response 
ratio determined from calibration data (Section 10.4) and the following 
equation:
[GRAPHIC] [TIFF OMITTED] TR15AP98.031

Where:

Cex = concentration of the pollutant in the extract.
An = area of the characteristic m/z for the pollutant.
Cl = concentration of the labeled compound in the extract.
Al = area of the characteristic m/z for the labeled compound.
RR = response ratio from the initial calibration.

    14.2.2 For the IPR (Section 9.3.2) and OPR (Section 9.6), compute 
the percent recovery of each pollutant using the equation in Section 
14.6. The percent recovery is used for the evaluation of method and 
laboratory performance, in the form of IPR (Section 9.3.2) and OPR 
(Section 9.6).
    14.3 Quantitative determination by internal standard: Compute the 
concentration using the response factor determined from calibration data 
(Section 10.5) and the following equation:
[GRAPHIC] [TIFF OMITTED] TR15AP98.032

Where:

Cex = concentration of the pollutant in the extract.
As = area of the characteristic m/z for the pollutant.
Cis = concentration of the internal standard in the extract 
          (see note below).
Ais = area of the characteristic m/z for the internal 
          standard.
RF = response factor from the initial calibration.

    Note: When this equation is used to compute the extract 
concentrations of native compounds without labeled analogs, use the

[[Page 237]]

area (Ais) and concentration (Cis) of 3,4,5-
trichlorophenol (SMIS) as the internal standard.

    For the IPR (Section 9.3.2) and OPR (Section 9.6), compute the 
percent recovery using the equation in Section 14.6.

    Note: Separate calibration curves will be required for samples with 
and without the addition of ascorbic acid, and also for both extraction 
procedures (stir-bar and separatory funnel) where applicable.

    14.4 Compute the concentration of the labeled compounds and the SMIS 
using the equation in Section 14.3, but using the area and concentration 
of the 2,2'-difluorobiphenyl as the internal standard, and the area of 
the labeled compound or SMIS as As.
    14.5 Compute the concentration of each pollutant compound in the 
sample using the following equation:
[GRAPHIC] [TIFF OMITTED] TR15AP98.033

Where:

Cs = Concentration of the pollutant in the sample.
Cex = Concentration of the pollutant in the extract.
Vex = Volume of the concentrated extract (typically 0.5 mL).
Vo = Volume of the original sample in liters.

    14.6 Compute the recovery of each labeled compound and the SMIS as 
the ratio of concentration (or amount) found to the concentration (or 
amount) spiked, using the following equation:
[GRAPHIC] [TIFF OMITTED] TR15AP98.034

    These percent recoveries are used to assess method performance 
according to Sections 9 and 13.
    14.7 If the EICP area at the quantitation m/z for any compound 
exceeds the calibration range of the system, three approaches are used 
to obtain results within the calibration range.
    14.7.1 If the recoveries of all the labeled compounds in the 
original sample aliquot meet the limits in Table 5, then the extract of 
the sample may be diluted by a maximum of a factor of 10, and the 
diluted extract reanalyzed.
    14.7.2 If the recovery of any labeled compound is outside its limits 
in Table 5, or if a tenfold dilution of the extract will not bring the 
pollutant within the calibration range, then extract and analyze a 
dilute aliquot of the sample (Section 11). Dilute 100 mL, 10 mL, or an 
appropriate volume of sample to 1000 mL with reagent water and extract 
per Section 11.
    14.7.3 If the recoveries of all labeled compounds in the original 
sample aliquot (Section 14.7.1) meet the limits in Table 5, and if the 
sample holding time has been exceeded, then the original sample extract 
is diluted by successive factors of 10, the DFB internal standard is 
added to give a concentration of 50 [micro]g/mL in the diluted extract, 
and the diluted extract is analyzed. Quantitation of all analytes is 
performed using the DFB internal standard.
    14.7.4 If the recoveries of all labeled compounds in the original 
sample aliquot (Section 14.7.1) or in the dilute aliquot (Section 
14.7.2) (if a dilute aliquot was analyzed) do not meet the limits in 
Table 5, and if the holding time has been exceeded, re-sampling is 
required.
    14.8 Results are reported for all pollutants, labeled compounds, and 
the sample matrix internal standard in standards, blanks, and samples, 
in units of [micro]g/L.
    14.8.1 Results for samples which have been diluted are reported at 
the least dilute level at which the area at the quantitation m/z is 
within the calibration range (Section 14.7).
    14.8.2 For compounds having a labeled analog, results are reported 
at the least dilute level at which the area at the quantitation m/z is 
within the calibration range (Section 14.7) and the labeled compound 
recovery is within the normal range for the method (Section 13.3).

                         15.0 Method Performance

    15.1 Single laboratory performance for this method is detailed in 
References 1, 2, and 11. Acceptance criteria were established from 
multiple laboratory use of the draft method.
    15.2 A chromatogram of the ongoing precision and recovery standard 
(Section 7.14) is shown in Figure 4.

                        16.0 Pollution Prevention

    16.1 The solvents used in this method pose little threat to the 
environment when recycled and managed properly.

[[Page 238]]

    16.2 Standards should be prepared in volumes consistent with 
laboratory use to minimize the volume of expired standards to be 
disposed.

                          17.0 Waste Management

    17.1 It is the laboratory's responsibility to comply with all 
federal, state, and local regulations governing waste management, 
particularly the hazardous waste identification rules and land disposal 
restrictions, and to protect the air, water, and land by minimizing and 
controlling all releases from fume hoods and bench operations. 
Compliance with all sewage discharge permits and regulations is also 
required.
    17.2 Samples preserved with HCl or H2SO4 to pH 
<2 are hazardous and must be neutralized before being disposed, or must 
be handled as hazardous waste.
    17.3 For further information on waste management, consult ``The 
Waste Management Manual for Laboratory Personnel'', and ``Less is 
Better: Laboratory Chemical Management for Waste Reduction'', both 
available from the American Chemical Society's Department of Government 
Relations and Science Policy, 1155 16th Street N.W., Washington, DC

\1\ Four digit numbers beginning with 10 indicate a pollutant quantified by the internal standard method; four
  digit numbers beginning with 11 indicate a labeled compound quantified by the internal standard method; four
  digit numbers beginning with 12 indicate a pollutant quantified by isotope dilution.
\2\ The retention times in this column are based on data from a single laboratory (reference 12), utilizing the
  GC conditions in Section 11.
\3\ Relative retention time windows are estimated from EPA Method 1625.
\4\ The minimum level (ML) is defined as the level at which the entire analytical system must give a
  recognizable signal and acceptable calibration point for the analyte. It is equivalent to the concentration of
  the lowest calibration standard, assuming that all method-specified sample weights, volumes, and cleanup
  procedures have been employed.

    20.2 Definitions and acronyms (in alphabetical order).
    Analyte: A chlorophenolic tested for by this method.
    The analytes are listed in Table 1.
    Calibration standard (CAL): A solution prepared from a secondary 
standard and/or stock solutions and used to calibrate the response of 
the instrument with respect to analyte concentration.

[[Page 246]]

    Calibration verification standard (VER): The mid-point calibration 
standard (CS3) that is used to verify calibration. See Table 4.
    Chlorophenolics: collectively, the analytes listed in Table 1.
    CS1, CS2, CS3, CS4, CS5: See Calibration standards and Table 4.
    Field blank: An aliquot of reagent water or other reference matrix 
that is placed in a sample container in the laboratory or the field, and 
treated as a sample in all respects, including exposure to sampling site 
conditions, storage, preservation, and all analytical procedures. The 
purpose of the field blank is to determine if the field or sample 
transporting procedures and environments have contaminated the sample.
    GC: Gas chromatograph or gas chromatography.
    HRGC: High resolution GC.
    IPR: Initial precision and recovery; four aliquots of the diluted 
PAR standard analyzed to establish the ability to generate acceptable 
precision and accuracy. An IPR is performed prior to the first time this 
method is used and any time the method or instrumentation is modified.
    K-D: Kuderna-Danish concentrator; a device used to concentrate the 
analytes in a solvent.
    Laboratory blank: See Method blank.
    Laboratory control sample (LCS): See Ongoing precision and recovery 
standard (OPR).
    Laboratory reagent blank: See Method blank.
    May: This action, activity, or procedural step is neither required 
nor prohibited.
    May not: This action, activity, or procedural step is prohibited.
    Method blank: An aliquot of reagent water that is treated exactly as 
a sample including exposure to all glassware, equipment, solvents, 
reagents, internal standards, and surrogates that are used with samples. 
The method blank is used to determine if analytes or interferences are 
present in the laboratory environment, the reagents, or the apparatus.
    Minimum level (ML): The level at which the entire analytical system 
must give a recognizable signal and acceptable calibration point for the 
analyte. It is equivalent to the concentration of the lowest calibration 
standard, assuming that all method-specified sample weights, volumes, 
and cleanup procedures have been employed.
    MS: Mass spectrometer or mass spectrometry.
    Must: This action, activity, or procedural step is required.
    OPR: Ongoing precision and recovery standard (OPR); a laboratory 
blank spiked with known quantities of analytes. The OPR is analyzed 
exactly like a sample. Its purpose is to assure that the results 
produced by the laboratory remain within the limits specified in this 
method for precision and recovery.
    PAR: Precision and recovery standard; secondary standard that is 
diluted and spiked to form the IPR and OPR.
    Preparation blank: See Method blank.
    Primary dilution standard: A solution containing the specified 
analytes that is purchased or prepared from stock solutions and diluted 
as needed to prepare calibration solutions and other solutions.
    Quality control check sample (QCS): A sample containing all or a 
subset of the analytes at known concentrations. The QCS is obtained from 
a source external to the laboratory or is prepared from a source of 
standards different from the source of calibration standards. It is used 
to check laboratory performance with test materials prepared external to 
the normal preparation process.
    Reagent water: Water demonstrated to be free from the analytes of 
interest and potentially interfering substances at the method detection 
limit for the analyte.
    Relative standard deviation (RSD): The standard deviation times 100 
divided by the mean.
    RF: Response factor. See Section 10.5.1.
    RR: Relative response. See Section 10.4.4.
    RSD: See Relative standard deviation.
    Should: This action, activity, or procedural step is suggested but 
not required.
    Stock solution: A solution containing an analyte that is prepared 
using a reference material traceable to EPA, the National Institute of 
Science and Technology (NIST), or a source that will attest to the 
purity and authenticity of the reference material.
    VER: See Calibration verification standard.

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.

[[Page 273]]

    (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.

Sec.  434.64  Procedure and method detection limit for measurement 
of settleable solids.

    For the purposes of this part, the following procedure shall be used 
to determine settleable solids: Fill an 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 
of this chapter, apply to have its NPDES permit modified to incorporate 
the revised new source performance standards.



                         Subpart G_Coal Remining

    Source: 67 FR 3406, Jan. 23, 2002, unless otherwise noted.



Sec.  434.70  Specialized definitions.

    (a) The term coal remining operation means a coal mining operation 
at a site on which coal mining was previously conducted and where the 
site has been abandoned or the performance bond has been forfeited.
    (b) The term pollution abatement area means the part of the permit 
area that is causing or contributing to the baseline pollution load of 
pre-existing discharges. The pollution abatement area must include, to 
the extent practicable, areas adjacent to and nearby the remining 
operation that also must be affected to reduce the pollution load of the 
pre-existing discharges and may include the immediate location of the 
pre-existing discharges.
    (c) The term pre-existing discharge means any discharge resulting 
from mining activities that have been abandoned prior to the time of a 
remining permit application. This term shall include a pre-existing 
discharge that is relocated as a result of the implementation of best 
management practices (BMPs) contained in the Pollution Abatement Plan.
    (d) The term steep slope means any slope above twenty degrees or 
such lesser slope as may be defined by the

[[Page 286]]

regulatory authority after consideration of soil, climate, and other 
characteristics of a region or State. This term does not apply to those 
situations in which an operator is mining on flat or gently rolling 
terrain, on which an occasional steep slope is encountered and through 
which the mining operation is to proceed, leaving a plain or 
predominantly flat area.
    (e) The term new source remining operation means a remining 
operation at a coal mine where mining first commences after February 22, 
2002 and subsequently becomes an abandoned mine.



Sec.  434.71  Applicability.

    (a) This subpart applies to pre-existing discharges that are located 
within or are hydrologically connected to pollution abatement areas of a 
coal remining operation.
    (b) A pre-existing discharge that is intercepted by active mining or 
that is commingled with waste streams from active mining areas for 
treatment is subject to the provisions of Sec.  434.61 Commingling of 
waste streams. For the purposes of this subpart, Sec.  434.61 requires 
compliance with applicable BPT, BAT, BCT, and NSPS effluent limitations 
in subparts C, D, and F of this part. Section 434.61 applies to the 
commingled waste stream only during the time when the pre-existing 
discharge is intercepted by active mining or is commingled with active 
mine wastewater for treatment or discharge. After commingling has 
ceased, the pre-existing discharge is subject to the provisions of this 
part.
    (c) In situations where coal remining operations seek reissuance of 
an existing remining permit with BPJ limitations and the regulatory 
authority determines that it is not feasible for a remining operator to 
re-establish baseline pollutant levels in accordance with the 
statistical procedures contained in appendix B of this part, pre-
existing discharge limitations at existing remining operations shall 
remain subject to baseline pollutant levels established during the 
original permit application.
    (d) The effluent limitations in this subpart apply to pre-existing 
discharges until the appropriate SMCRA authority has authorized bond 
release.



Sec.  434.72  Effluent limitations attainable by the application of the best 
practicable control technology currently available (BPT).

    (a) The operator must submit a site-specific Pollution Abatement 
Plan to the permitting authority for the pollution abatement area. The 
plan must be approved by the permitting authority and incorporated into 
the permit as an effluent limitation. The Pollution Abatement Plan must 
identify characteristics of the pollution abatement area and the pre-
existing discharges. The Pollution Abatement Plan must be designed to 
reduce the pollution load from pre-existing discharges and must identify 
the selected best management practices (BMPs) to be used. The plan must 
describe the design specifications, construction specifications, 
maintenance schedules, criteria for monitoring and inspection, and 
expected performance of the BMPs. The BMPs must be implemented as 
specified in the plan.
    (b) (1) Except as provided in 40 CFR 125.30 through 125.32 and 
paragraph (b)(2) of this section, the following effluent limits apply to 
pre-existing discharges:

                                          by appendix B of this part).
                                         Prior to bond release, the pre-
                                          existing discharge must meet
                                          the applicable standards for
                                          TSS or SS contained in subpart
                                          E. \1\
------------------------------------------------------------------------
\1\ A pre-existing discharge is exempt from meeting standards in subpart
  E of this part for TSS and SS when the permitting authority determines
  that subpart E standards are infeasible or impractical based on the
  site-specific conditions of soil, climate, topography, steep slopes,
  or other baseline conditions provided that the operator demonstrates
  that significant reductions of TSS and SS will be achieved through the
  incorporation of sediment control BMPs into the Pollution Abatement
  Plan as required by paragraph (a) of this section.

    (2) If the permitting authority determines that it is infeasible to 
collect samples for establishing the baseline pollutant levels pursuant 
to paragraph (b)(1) of this section, and that remining will result in 
significant improvement that would not otherwise occur, then the numeric 
effluent limitations in paragraph (b)(1) of this section do not apply. 
Pre-existing discharges for which it is infeasible to collect samples 
for determination of baseline pollutant levels include, but are not 
limited to, discharges that exist as a diffuse groundwater flow that 
cannot be assessed via sample collection; a base flow to a receiving 
stream that cannot be monitored separate from the receiving stream; a 
discharge on a steep or hazardous slope that is inaccessible for sample 
collection; or, a number of pre-existing discharges so extensive that 
monitoring of individual discharges is infeasible.

   Sec. Appendix B to Part 434--Baseline Determination and Compliance 
      Monitoring for Pre-existing Discharges at Remining Operations

                    I. General Procedure Requirements

    a. This appendix presents the procedures to be used for establishing 
effluent limitations for pre-existing discharges at coal remining 
operations, in accordance with the requirements set forth in subpart G; 
Coal Remining. The requirements specify that pollutant loadings of total 
iron, total manganese, total suspended solids, and net acidity in pre-
existing discharges shall not exceed baseline pollutant loadings. The 
procedures described in this appendix shall be used for determining 
site-specific, baseline pollutant loadings, and for determining whether 
discharge loadings during coal remining operations have exceeded the 
baseline loading. Both a monthly (single-observation) procedure and an 
annual procedure shall be applied, as described below.
    b. In order to sufficiently characterize pollutant loadings during 
baseline determination and during each annual monitoring period, it is 
required that at least one sample result be obtained per month for a 
period of 12 months.
    c. Calculations described in this appendix must be applied to 
pollutant loadings. Each loading value is calculated as the product of a 
flow measurement and pollutant concentration taken on the same date at 
the same discharge sampling point, using standard units of flow and 
concentration (to be determined by the permitting authority). For 
example, flow may be measured in cubic feet per second, concentration in 
milligrams per liter, and the pollutant loading could be calculated in 
pounds per year.
    d. Accommodating Data Below the Maximum Daily Limit at subpart C of 
this part. In the event that a pollutant concentration in the data used 
to determine baseline is lower than the daily maximum limitation 
established in subpart C of this part for active mine wastewater, the 
statistical procedures should not establish a baseline more stringent 
than the BPT and BAT effluent standards established in subpart C of this 
part. Therefore, if the total iron concentration in a baseline sample is 
below 7.0 mg/L, or the total manganese concentration is below 4.0 mg/L, 
the baseline sample concentration may be replaced with 7.0 mg/L and 4.0 
mg/L, respectively, for the purposes of some of the statistical 
calculations in this appendix B. The substituted values should be used 
for all methods in this appendix B with the exception of the calculation 
of the interquartile range (R) in Method 1 for the annual trigger (Step 
3), and in Method 2 for the single observation trigger (Step 3). The 
interquartile range (R) is the difference between the quartiles 
M-1 and M1; these values should be calculated 
using actual loadings (based on measured concentrations) when they are 
used to calculate R. This should be done in order to account for the 
full range of variability in the data.

    II. Procedure for Calculating and Applying a Single-Observation 
                            (Monthly) Trigger

    Two alternative methods are provided for calculating a single-
observation trigger. One method must be selected and applied by the 
permitting authority for any given remining permit.

      A. Method 1 for Calculating a Single Observation Trigger (L)

    (1) Count the number of baseline observations taken for the 
pollutant of interest. Label this number n. In order to sufficiently 
characterize pollutant loadings during baseline determination and during 
each annual monitoring period, it is required that at least one sample 
result be obtained per month for a period of 12 months.
    (2) Order all baseline loading observations from lowest to highest. 
Let the lowest number (minimum) be x(1), the next lowest be 
x(2), and so forth until the highest number (maximum) is 
x(n).
    (3) If fewer than 17 baseline observations were obtained, then the 
single observation trigger (L) will equal the maximum of the baseline 
observations (x(n)).
    (4) If at least 17 baseline observations were obtained, calculate 
the median (M) of all baseline observations:
    Instructions for calculation of a median of n observations:
    If n is odd, then M equals x(n/2 + 1/2).
    For example, if there are 17 observations, then M = 
X(17/2 + 1/2) = x(9), the 9th highest 
observation.
    If n is even, then M equals 0.5 * (x(n/2) + 
x(n/2 + 1)).
    For example, if there are 18 observations, then M equals 0.5 
multiplied by the sum of the 9th and 10th highest observations.
    (a) Next, calculate M1 as the median of the subset of 
observations that range from the calculated M to the maximum 
x(n); that is, calculate the median of all x larger than or 
equal to M.
    (b) Next, calculate M2 as the median of the subset of 
observations that range from the calculated M1 to 
x(n) ; that is, calculate the median of all x larger than or 
equal to M1.
    (c) Next, calculate M3 as the median of the subset of 
observations that range from the calculated M2 to 
x(n) ; that is, calculate the median of all x larger than or 
equal to M2.
    (d) Finally, calculate the single observation trigger (L) as the 
median of the subset of observations that range from the calculated 
M3 to x(n).

[[Page 291]]

    Note: When subsetting the data for each of steps 3a-3d, the subset 
should include all observations greater than or equal to the median 
calculated in the previous step. If the median calculated in the 
previous step is not an actual observation, it is not included in the 
new subset of observations. The new median value will then be calculated 
using the median procedure, based on whether the number of points in the 
subset is odd or even.
    (5) Method for applying the single observation trigger (L) to 
determine when the baseline level has been exceeded
    If two successive monthly monitoring observations both exceed L, 
immediately begin weekly monitoring for four weeks (four weekly 
samples).
    (a) If three or fewer of the weekly observations exceed L, resume 
monthly monitoring
    (b) If all four weekly observations exceed L, the baseline pollution 
loading has been exceeded.

      B. Method 2 for Calculating a Single Observation Trigger (L)

    (1) Follow Method 1 above to obtain M1 (the third 
quartile, that is, the 75th percentile).
    (2) Calculate M-1 as the median of the baseline data 
which are less than or equal to the sample median M.
    (3) Calculate interquartile range, R = (M1 - 
M-1).
    (4) Calculate the single observation trigger L as

L = M1 + 3 * R

    (5) If two successive monthly monitoring observations both exceed L, 
immediately begin weekly monitoring for four weeks (four weekly 
samples).
    (a) If three or fewer of the weekly observations exceed L, resume 
monthly monitoring
    (b) If all four weekly observations exceed L, the baseline pollution 
loading has been exceeded.

      III. Procedure for Calculating and Applying an Annual Trigger

     A. Method 1 for Calculating and Applying an Annual Trigger (T)

    (1) Calculate M and M1 of the baseline loading data as 
described above under Method 1 for the single observation trigger.
    (2) Calculate M-1 as the median of the baseline data 
which are less than or equal to the sample median M.
    (3) Calculate the interquartile range, R = (M1 - 
M-1).
    (4) The annual trigger for baseline (Tb) is calculated as:
    [GRAPHIC] [TIFF OMITTED] TR23JA02.002
    
where n is the number of baseline loading observations.
    (5) To compare baseline loading data to observations from the annual 
monitoring period, repeat steps 1-3 for the set of monitoring 
observations. Label the results of the calculations M' and R'. Let m be 
the number of monitoring observations.
    (6) The subtle trigger (Tm) of the monitoring data is calculated as:
    [GRAPHIC] [TIFF OMITTED] TR23JA02.003
    
    (7) If Tm Tb, the median loading of the monitoring 
observations has exceeded the baseline loading.

     B. Method 2 for Calculating and Applying an Annual Trigger (T)

    Method 2 applies the Wilcoxon-Mann-Whitney test to determine whether 
the median loading of the monitoring observations has exceeded the 
baseline median. No baseline value T is calculated.

         (1) Steps for Conducting the Wilcoxon-Mann-Whitney Test

    (a) Let n be the number of baseline loading observations taken, and 
let m be the number of monitoring loading observations taken. In order 
to sufficiently characterize pollutant loadings during baseline 
determination and during each annual monitoring period, it is required 
that at least one sample result be obtained per month for a period of 12 
months.
    (b) Order the combined baseline and monitoring observations from 
smallest to largest.
    (c) Assign a rank to each observation based on the assigned order: 
the smallest observation will have rank 1, the next smallest will have 
rank 2, and so forth, up to the highest observation, which will have 
rank n + m.
    (1) If two or more observations are tied (have the same value), then 
the average rank for those observations should be used. For example, 
suppose the following four values are being ranked:

3, 4, 6, 4

Since 3 is the lowest of the four numbers, it would be assigned a rank 
of 1. The highest of the four numbers is 6, and would be assigned a rank 
of 4. The other two numbers are both 4. Rather than assign one a rank of 
2 and the other a rank of 3, the average of 2 and 3 (i.e., 2.5) is given 
to both numbers.
    (d) Sum all the assigned ranks of the n baseline observations, and 
let this sum be Sn.
    (e) Obtain the critical value (C) from Table 1. When 12 monthly data 
are available for both baseline and monitoring (i.e., n = 12 and m = 
12), the critical value C is 99.
    (f) Compare C to Sn. If Sn is less than C, 
then the monitoring loadings have exceeded the baseline loadings.

cleaning stations, and galleys located within facilities subject to this 
subpart.
    (k) Drill cuttings means the particles generated by drilling into 
subsurface geologic formations and carried out from the wellbore with 
the drilling fluid. Examples of drill cuttings include small pieces of

approved for use with this part are published as appendices to subpart A 
of this part and in ``Analytic Methods for the Oil and Gas Extraction

[[Page 296]]

Point Source Category,'' EPA-821-R-11-004. See paragraph (uu) of this 
section. Detection of formation oil by the RPE method may be confirmed 
by the GC/MS compliance assurance method, and the results of the GC/MS 
compliance assurance method shall apply instead of those of the RPE 
method.
    (p) M9IM means those offshore facilities continuously manned by nine 
(9) or fewer persons or only intermittently manned by any number of 
persons.
    (q) M10 means those offshore facilities continuously manned by ten

water; drilling fluids or cuttings may not be discharged when they fail 
EPA Method 1617 (Static Sheen Test), which is published as an appendix 
to subpart A of this part and in ``Analytic Methods for the Oil and Gas 
Extraction Point Source Category,'' EPA-821-R-11-004. See paragraph (uu) 
of this section.
    (y) Parameters that are regulated in this subpart and listed with 
approved methods of analysis in Table 1B at 40 CFR 136.3 are defined as 
follows:

[[Page 297]]

    (1) Cadmium means total cadmium.
    (2) Chlorine means total residual chlorine.
    (3) Mercury means total mercury.
    (4) Oil and Grease means total recoverable oil and grease.
    (z) PAH (as phenanthrene) means polynuclear aromatic hydrocarbons 
reported as phenanthrene.
    (aa) Produced sand means the slurried particles used in hydraulic 
fracturing, the accumulated formation sands and scales particles 
generated during production. Produced sand also includes desander 
discharge from the produced water waste stream, and blowdown of the 
water phase from the produced water treating system.
    (bb) Produced water means the water (brine) brought up from the 
hydrocarbon-bearing strata during the extraction of oil and gas, and can 
include formation water, injection water, and any chemicals added 
downhole or during the oil/water separation process.
    (cc) Production facility means any fixed or mobile structure subject 
to this subpart that is either engaged in well completion or used for 
active recovery of hydrocarbons from producing formations.
    (dd) Sanitary waste means the human body waste discharged from 
toilets and urinals located within facilities subject to this subpart.
    (ee) Sediment toxicity as applied to BAT effluent limitations and 
NSPS for drilling fluids and drill cuttings refers to EPA Method 1644: 
``Method for Conducting a Sediment Toxicity Test with Leptocheirus 
plumulosus and Non-Aqueous Drilling Fluids or Synthetic-Based Drilling 
Muds'' and sediment preparation procedures specified in EPA Method 1646. 
EPA Method 1644 is published in ``Analytic Methods for the Oil and Gas 
Extraction Point Source Category,'' (see paragraph (uu) of this section) 
and EPA Method 1646 is published as an appendix to subpart A of this 
part.
    (ff) Solids control equipment means shale shakers, centrifuges, mud 
cleaners, and other equipment used to separate drill cuttings and/or 
stock barite solids from drilling fluid recovered from the wellbore.
    (gg) SPP toxicity as applied to BAT effluent limitations and NSPS 
for drilling fluids and drill cuttings refers to the bioassay test 
procedure, ``Suspended Particulate Phase (SPP) Toxicity Test,'' 
presented in EPA Method 1619, which is published as an appendix to 
subpart A of this part and in ``Analytic Methods for the Oil and Gas 
Extraction Point Source Category,'' EPA-821-R-11-004. See paragraph (uu) 
of this section.
    (hh) Static sheen test means the standard test procedure that has 
been developed for this industrial subcategory for the purpose of 
demonstrating compliance with the requirement of no discharge of free 
oil. The methodology for performing the static sheen test is presented 
in EPA Method 1617, which is published as an appendix to subpart A of 
this part and in ``Analytic Methods for the Oil and Gas Extraction Point 
Source Category,'' EPA-821-R-11-004. See paragraph (uu) of this section.
    (ii) Stock barite means the barite that was used to formulate a 
drilling fluid.
    (jj) Stock base fluid means the base fluid that was used to 
formulate a drilling fluid.
    (kk) Synthetic material as applied to synthetic-based drilling fluid 
means material produced by the reaction of specific purified chemical 
feedstock, as opposed to the traditional base fluids such as diesel and 
mineral oil which are derived from crude oil solely through physical 
separation processes. Physical separation processes include 
fractionation and distillation and/or minor chemical reactions such as 
cracking and hydro processing. Since they are synthesized by the 
reaction of purified compounds, synthetic materials suitable for use in 
drilling fluids are typically free of polycyclic aromatic hydrocarbons 
(PAH's) but are sometimes found to contain levels of PAH up to 0.001 
weight percent PAH expressed as phenanthrene. Internal olefins and 
vegetable esters are two examples of synthetic materials suitable for 
use by the oil and gas extraction industry in formulating drilling 
fluids. Internal olefins are synthesized from the isomerization of 
purified straight-chain (linear) hydrocarbons such as C16-
C18 linear alpha olefins. C16-C18 
linear alpha olefins are unsaturated hydrocarbons with the carbon to 
carbon double bond in the terminal position.

[[Page 298]]

Internal olefins are typically formed from heating linear alpha olefins 
with a catalyst. The feed material for synthetic linear alpha olefins is 
typically purified ethylene. Vegetable esters are synthesized from the 
acid-catalyzed esterification of vegetable fatty acids with various 
alcohols. EPA listed these two branches of synthetic fluid base 
materials to provide examples, and EPA does not mean to exclude other 
synthetic materials that are either in current use or may be used in the 
future. A synthetic-based drilling fluid may include a combination of 
synthetic materials.
    (ll) Well completion fluids means salt solutions, weighted brines, 
polymers, and various additives used to prevent damage to the well bore 
during operations which prepare the drilled well for hydrocarbon 
production.
    (mm) Well treatment fluids means any fluid used to restore or 
improve productivity by chemically or physically altering hydrocarbon-
bearing strata after a well has been drilled.
    (nn) Workover fluids means salt solutions, weighted brines, 
polymers, or other specialty additives used in a producing well to allow 
for maintenance, repair or abandonment procedures.
    (oo) 4-day LC5. as applied to the sediment toxicity BAT 
effluent limitations and NSPS means the concentration (milligrams/
kilogram dry sediment) of the drilling fluid in sediment that is lethal 
to 50 percent of the Leptocheirus plumulosus test organisms exposed to 
that concentration of the drilling fluids after four days of constant 
exposure.
    (pp) 10-day LC5. as applied to the sediment toxicity BAT 
effluent limitations and NSPS means the concentration (milligrams/
kilogram dry sediment) of the base fluid in sediment that is lethal to 
50 percent of the Leptocheirus plumulosus test organisms exposed to that 
concentration of the base fluids after ten days of constant exposure.
    (qq) 96-hour LC5. means the concentration (parts per 
million) or percent of the suspended particulate phase (SPP) from a 
sample that is lethal to 50 percent of the test organisms exposed to 
that concentration of the SPP after 96 hours of constant exposure.
    (rr) C16-C18 internal olefin means a 65/35 blend, proportioned by 
mass, of hexadecene and octadecene, respectively. Hexadecene is an 
unsaturated hydrocarbon with a carbon chain length of 16, an internal 
double carbon bond, and is represented by the Chemical Abstracts Service 
(CAS) No. 26952-14-7. Octadecene is an unsaturated hydrocarbon with a 
carbon chain length of 18, an internal double carbon bond, and is 
represented by the Chemical Abstracts Service (CAS) No. 27070-58-2. 
(Properties available from the Chemical Abstracts Service, 2540 
Olentangy River Road, PO Box 3012, Columbus, OH, 43210).
    (ss) C16-C18 internal olefin drilling fluid 
means a C16-C18 internal olefin drilling fluid 
formulated as specified in appendix 1 of subpart A of this part.
    (tt) C12-C14 ester and C8 ester means the fatty acid/2-ethylhexyl 
esters with carbon chain lengths ranging from 8 to 16 and represented by 
the Chemical Abstracts Service (CAS) No. 135800-37-2. (Properties 
available from the Chemical Abstracts Service, 2540 Olentangy River 
Road, PO Box 3012, Columbus, OH, 43210)
    (uu) Analytic Methods for the Oil and Gas Extraction Point Source 
Category is the EPA document, ``Analytic Methods for the Oil and Gas 
Point Source Category,'' December 2011, EPA-821-R-11-004, that compiles 
analytic methods for this category. This incorporation by reference was

Sec. Appendix 1 to Subpart A of Part 435--Static Sheen Test (EPA Method 
                                  1617)

                        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 cm\2\ (155.5 in\2\). 
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.
    4.1.4 Triple-beam scale.
    4.1.5 Disposable pipettes: 25-mL disposable pipettes.
    4.1.6 Magnetic stirrer and stirring bar.

                             5. Calibration

    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.

[[Page 304]]

                              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 
cm\2\. 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 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.



Sec. Appendix 2 to Subpart A of Part 435--Drilling Fluids Toxicity Test 
                            (EPA Method 1619)

                          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

[[Page 305]]

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.

                 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.

[[Page 306]]

    (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. 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) Each definitive test consists of 18 test containers: 3 
replicates of a control and 5 SPP dilutions. Test containers should be 
Pyrex or equivalent glass. For definitive tests, 5 SPP dilutions with 3 
replicates of at least 500 ml each are required. Twenty mysids per 
replicate, 360 per definitive test are required.

                  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 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 20 2 ppt. Experimental temperature 
should be 20 2 [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.

[[Page 307]]

    (2) Establish the definitive test concentrations based on results of 
a range finding test or based on prior experience and knowledge of the 
mud system.
    (3) Twenty organisms are exposed in each test dish. Nytex [supreg] 
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, 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 308]]

[GRAPHIC] [TIFF OMITTED] TC01MY92.114

    (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.

[[Page 309]]

    (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.
    (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

[[Page 310]]

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.

  Sec. Appendix 3 to Subpart A of Part 435--Procedure for Mixing Base 
                 Fluids With Sediments (EPA Method 1646)

    This procedure describes a method for amending uncontaminated and 
nontoxic (control) sediments with the base fluids that are used to 
formulate synthetic-based drilling fluids and other non-aqueous drilling 
fluids. Initially, control sediments shall be press-sieved through a 
2000 micron mesh sieve to remove large debris. Then press-sieve the 
sediment through a 500 micron sieve to remove indigenous organisms that 
may prey on the test species or otherwise confound test results. 
Homogenize control sediment to limit the effects of settling that

[[Page 311]]

may have occurred during storage. Sediments should be homogenized before 
density determinations and addition of base fluid to control sediment. 
Because base fluids are strongly hydrophobic and do not readily mix with 
sediment, care must be taken to ensure base fluids are thoroughly 
homogenized within the sediment. All concentrations are weight-to-weight 
(mg of base fluid to kg of dry control sediment). Sediment and base 
fluid mixing shall be accomplished by using the following method.
    1. Determine the wet to dry ratio for the control sediment by 
weighing approximately 10 g subsamples of the screened and homogenized 
wet sediment into tared aluminum weigh pans. Dry sediment at 105 [deg]C 
for 18-24 h. Remove sediment and cool in a desiccator until a constant 
weight is achieved. Re-weigh the samples to determine the dry weight. 
Determine the wet/dry ratio by dividing the net wet weight by the net 
dry weight:

[Wet Sediment Weight (g)]/[Dry Sediment Weight (g)] = Wet to Dry Ratio 
[1]

    2. Determine the density (g/mL) of the wet control or dilution 
sediment. This shall be used to determine total volume of wet sediment 
needed for the various test treatments.

[Mean Wet Sediment Weight (g)]/[Mean Wet Sediment Volume (mL)] = Wet 
Sediment Density (g/mL) [2]

    3. To determine the amount of base fluid needed to obtain a test 
concentration of 500 mg base fluid per kg dry sediment use the following 
formulas:
    Determine the amount of wet sediment required:

[Wet Sediment Density (g/mL)] x [Volume of Sediment Required per 
Concentration (mL)] = Weight Wet Sediment Required per Conc. (g) [3]

    Determine the amount of dry sediment in kilograms (kg) required for 
each concentration:

{[Wet Sediment per Concentration (g)]/[Mean Wet to Dry Ratio]{time}  x 
(1kg/1000g) = Dry Weight Sediment (kg) [4]

    Finally, determine the amount of base fluid required to spike the 
control sediment at each concentration:

[Conc. Desired (mg/kg)] x [Dry Weight Sediment (kg)] = Base Fluid 
Required (mg) [5]

    For spiking test substances other than pure base fluids (e.g., whole 
mud formulations), determine the spike amount as follows:

[Conc. Desired (mL/kg)] x [Dry Weight Sediment (kg)] x [Test Substance 
Density (g/mL)] = Test Substance Required (g) [6]

    4. For primary mixing, place appropriate amounts of weighed base 
fluid into stainless mixing bowls, tare the vessel weight, then add 
sediment and mix with a high-shear dispersing impeller for 9 minutes. 
The concentration of base fluid in sediment from this mix, rather than 
the nominal concentration, shall be used in calculating LC5. 
values.
    5. Tests for homogeneity of base fluid in sediment are to be 
performed during the procedure development phase. Because of difficulty 
of homogeneously mixing base fluid with sediment, it is important to 
demonstrate that the base fluid is evenly mixed with sediment. The 
sediment shall be analyzed for total petroleum hydrocarbons (TPH) using 
EPA Methods 3550A and 8015M, with samples taken both prior to and after 
distribution to replicate test containers. Base-fluid content is 
measured as TPH. After mixing the sediment, a minimum of three replicate 
sediment samples shall be taken prior to distribution into test 
containers. After the test sediment is distributed to test containers, 
an additional three sediment samples shall be taken from three test 
containers to ensure proper distribution of base fluid within test 
containers. Base-fluid content results shall be reported within 48 hours 
of mixing. The coefficient of variation (CV) for the replicate samples 
must be less than 20%. If base-fluid content results are not within the 
20% CV limit, the test sediment shall be remixed. Tests shall not begin 
until the CV is determined to be below the maximum limit of 20%. During 
the test, a minimum of three replicate containers shall be sampled to 
determine base-fluid content during each sampling period.
    6. Mix enough sediment in this way to allow for its use in the 
preparation of all test concentrations and as a negative control. When 
commencing the sediment toxicity test, range-finding tests may be 
required to determine the concentrations that produce a toxic effect if 
these data are otherwise unavailable. The definitive test shall bracket 
the LC5., which is the desired endpoint. The results for the 
base fluids shall be reported in mg of base fluid per kg of dry 
sediment.

Sec. Appendix 4 to Subpart A of Part 435--Protocol for the Determination 
  of Degradation of Non-Aqueous Base Fluids in a Marine Closed Bottle 
  Biodegradation Test System: Modified ISO 11734:1995 (EPA Method 1647)

                     1.0. Summary of EPA Method 1647

    a. This method determines the anaerobic degradation potential of 
mineral oils, paraffin oils and non-aqueous fluids (NAF) in sediments. 
These substrates are base fluids for formulating offshore drilling 
fluids. The test evaluates base fluid biodegradation rates by monitoring 
gas production due to microbial degradation of the test fluid in natural 
marine sediment.
    b. The test procedure places a mixture of marine/estuarine sediment, 
test substrate (hydrocarbon or controls) and seawater into clean 120 mL 
(150 mL actual volume) Wheaton serum bottles. The test is run using four 
replicate serum bottles containing 2,000 mg carbon/kg dry weight 
concentration of test substrate in sediment. The use of resazurin dye 
solution (1 ppm) evaluates the anaerobic (redox) condition of the 
bottles (dye is blue when oxygen is present, reddish in low oxygen 
conditions and colorless if oxygen free). After capping the bottles, a 
nitrogen sparge removes air in the headspace before incubation begins. 
During the incubation period, the sample should be kept at a constant 
temperature of 29 1 [deg]C. Gas production and 
composition is measured approximately every two weeks. The samples need 
to be brought to ambient temperature before making the measurements. 
Measure gas production using a pressure gauge. Barometric pressure is 
measured at the time of testing to make necessary volume adjustments.
    c. ISO 11734:1995 specifies that total gas is the standard measure 
of biodegradation. While modifying this test for evaluating 
biodegradation of NAFs, methane was also monitored and found to be an 
acceptable method of evaluating biodegradation. Section 7 contains the 
procedures used to follow biodegradation by methane production. 
Measurement of either total gas or methane production is permitted. If 
methane is followed, determine the composition of the gas by using gas 
chromatography (GC) analysis at each sampling. At the end of the test 
when gas production stops, or at around 275 days, an analysis of 
sediment for substrate content is possible. Common methods which have 
been successfully used for analyzing NAFs from sediments are listed in 
Section 8.

                         2.0 System Requirements

    This environmental test system has three phases, spiked sediment, 
overlying seawater, and a gas headspace. The sediment/test compound 
mixture is combined with synthetic sea water and transferred into 120-mL 
serum bottles. The total volume of sediment/sea water mixture in the 
bottles is 75 mL. The volume of the sediment layer will be approximately 
50 mL, but the exact volume of the sediment will depend on sediment 
characteristics (wet:dry ratio and density). The amount of synthetic sea 
water will be calculated to bring the total volume in the bottles to 75 
mL. The test systems are maintained at a temperature of 29 1 [deg]C during incubation. The test systems are brought 
to ambient temperatures prior to measuring pressure or gas volume.

                         2.1 Sample Requirements

    a. The concentration of base fluids are at least 2,000 mg carbon 
test material/kg dry sediment. Carbon concentration is determined by 
theoretical composition based on the chemical formula or by chemical 
analysis by ASTM D5291-96. Sediments with positive, intermediate and 
negative control substances as well as a C16-C18 
internal olefin type base fluid will be run in conjunction with test 
materials under the same conditions. The positive control is ethyl 
oleate (CAS 111-62-6), the intermediate control is 1-hexadecene (CAS 
629-73-2), and the negative control is squalane (CAS 111-01-3). Controls 
must be of analytical grade or the highest grade available. Each test 
control concentration should be prepared according to the mixing 
procedure described in Section 3.1.
    b. Product names will be used for examples or clarification in the 
following text. Any use of trade or product names in this publication is 
for descriptive use only, and does not constitute endorsement by EPA or 
the authors.

                       2.2. Seawater Requirements

    Synthetic seawater at a salinity of 25 1 ppt 
should be used for the test. The synthetic seawater should be prepared 
by mixing a commercially available artificial seawater mix, into high 
purity distilled or de-ionized water. The seawater should be aerated and 
allowed to age for approximately one month prior to use.

                       2.3. Sediment Requirements

    a. The dilution sediment must be from a natural estuarine or marine 
environment and be free of the compounds of interest. The collection 
location, date and time will be documented and reported. The sediment is 
prepared by press-sieving through a 2,000-micron mesh sieve to remove 
large debris, then press-sieving through a 500-micron sieve to

[[Page 313]]

remove indigenous organisms that may confound test results. The water 
content of the sediment should be less than 60% (w/w) or a wet to dry 
ratio of 2.5. The sediment should have a minimum organic matter content 
of 3% (w/w) as determined by ASTM D2974-07a (Method A and D and 
calculate organic matter as in Section 8.3 of method ASTM D2974-07a).
    b. To reduce the osmotic shock to the microorganisms in the sediment 
the salinity of the sediment's pore water should be between 20-30 ppt. 
Sediment should be used for testing as soon as possible after field 
collection. If required, sediment can be stored in the dark at 4 [deg]C 
with 3-6 inches of overlying water in a sealed container for a maximum 
period of 2 months prior to use.

                             3.0 Test Set Up

    The test is set up by first mixing the test or control substrates 
into the sediment inoculum, then mixing in seawater to make a pourable 
slurry. The slurry is then poured into serum bottles, which are then 
flushed with nitrogen and sealed.

                          3.1. Mixing Procedure

    Because base fluids are strongly hydrophobic and do not readily mix 
with sediments, care must be taken to ensure base fluids are thoroughly 
homogenized within the sediment. All concentrations are weight-to-weight 
comparisons (mg of base fluid to kg of dry control sediment). Sediment 
and base fluid mixing will be accomplished by using the following 
method.
    3.1.1. Determine the wet to dry weight ratio for the control 
sediment by weighing approximately 10 sub-samples of approximately 1 g 
each of the screened and homogenized wet sediment into tared aluminum 
weigh pans. Dry sediment at 105 [deg]C for 18-24 h. Remove the dried 
sediments and cool in a desiccator. Repeat the drying, cooling, and 
weighing cycle until a constant weight is achieved (within 4% of 
previous weight). Re-weigh the samples to determine the dry weight. 
Calculate the mean wet and dry weights of the 10 sub samples and 
determine the wet/dry ratio by dividing the mean wet weight by the mean 
dry weight using Equation 5-1. This is required to determine the weight 
of wet sediment needed to prepare the test samples.

    3.1.2. Determine the density (g/ml) of the wet sediment. This will 
be used to determine total volume of wet sediment needed for the various 
test treatments. One method is to tare a 5 ml graduated cylinder and add 
about 5 ml of homogenized sediment. Carefully record the volume then 
weigh this volume of sediment. Repeat this a total of three times. To 
determine the wet sediment density, divide the weight by volume per the 
following formula:
[GRAPHIC] [TIFF OMITTED] TR18MY12.009

    3.1.3. Determine the amount of base fluid to be spiked into wet 
sediment in order to obtain the desired initial base fluid concentration 
of 2,000 mg carbon/kg dry weight. An amount of wet sediment that is the 
equivalent of 30 g of dry sediment will be added to each bottle. A 
typical procedure is to prepare enough sediment for 8 serum bottles (3 
bottles to be sacrificed at the start of the test, 4 bottles incubated 
for headspace analysis, and enough extra sediment for 2 extra bottles). 
Extra sediment is needed because some of the sediment will remain coated 
onto the mixing bowl and utensils. Experience with this test may 
indicate that preparing larger volumes of spiked sediment is a useful 
practice, then the following calculations should be adjusted 
accordingly.
    a. Determine the total weight of dry sediment needed to add 30 g dry 
sediment to 8 bottles. If more bottles are used then the calculations 
should be modified accordingly. For example:

[[Page 314]]

[GRAPHIC] [TIFF OMITTED] TR18MY12.010

    b. Determine the weight of base fluid, in terms of carbon, needed to 
obtain a final base fluid concentration of 2,000 mg carbon/kg dry 
weight. For example:
[GRAPHIC] [TIFF OMITTED] TR18MY12.011

    c. i. Convert from mg of carbon to mg of base fluid. This 
calculation will depend on the % fraction of carbon present in the 
molecular structure of each base fluid. For the control fluids, ethyl 
oleate is composed of 77.3% carbon, hexadecene is composed of 85.7% 
carbon, and squalane is composed of 85.3% carbon. The carbon fraction of 
each base fluid should be supplied by the manufacturer or determined 
before use. ASTM D5291-96 or equivalent will be used to determine 
composition of fluid.
    ii. To calculate the amount of base fluid to add to the sediment, 
divide the amount of carbon (480 mg) by the percent fraction of carbon 
in the fluid.
    iii. For example, the amount of ethyl oleate added to 240 g dry 
weight sediment can be calculated from the following equation:
[GRAPHIC] [TIFF OMITTED] TR18MY12.012

    iv. Therefore, add 621 mg of ethyl oleate to 240 g dry weight 
sediment for a final concentration of 2,000 mg carbon/kg sediment dry 
weight.
    3.1.4. Mix the calculated amount of base fluid with the appropriate 
weight of wet sediment.
    a. Use the wet:dry ratio to convert from g sediment dry weight to g 
sediment wet weight, as follows:
[GRAPHIC] [TIFF OMITTED] TR18MY12.013

    b. i. Weigh the appropriate amount of base fluid (calculated in 
Section 3.1.3.c) into stainless mixing bowls, tare the vessel weight, 
then add the wet sediment calculated in Equation 5, and mix with a high 
shear dispersing impeller for 9 minutes.
    ii. The sediment is now mixed with synthetic sea water to form a 
slurry that will be transferred into the bottles.
    3.2. Creating Seawater/Sediment Slurry
    Given that the total volume of sediment/sea water slurry in each 
bottle is to be 75 mL, determine the volume of sea water to add to the 
wet sediment.
    3.2.1. If each bottle is to contain 30 g dry sediment, calculate the 
weight, and then the volume, of wet sediment to be added to each bottle.

[[Page 315]]

[GRAPHIC] [TIFF OMITTED] TR18MY12.014

    3.2.4. Convert the wet sediment weight from Equation 6 into a volume 
using the sediment density.
[GRAPHIC] [TIFF OMITTED] TR18MY12.016

    3.2.5. Determine the amount of sea water to mix with the wet 
sediment.
[GRAPHIC] [TIFF OMITTED] TR18MY12.017

    Mix sea water thoroughly with wet sediment to form a sediment/sea 
water slurry.
    3.3. Bottling the Sediment Seawater Slurry
    The total volume of sediment/sea water slurry in each bottle is to 
be 75 mL. Convert the volume (mL) of sediment/sea water slurry into a 
weight (g) using the density of the sediment and the seawater.
[GRAPHIC] [TIFF OMITTED] TR18MY12.018

    This should provide each bottle with 30 g dry sediment in a total 
volume of 75 mL.
    3.3.4. Putting the sediment:seawater slurry in the serum bottles.

[[Page 316]]

    a. Note: The slurry will need to be constantly stirred to keep the 
sediment suspended.
    b. Place a tared serum bottle on a balance and add the appropriate 
amount of slurry to the bottle using a funnel. Once the required slurry 
is in the bottle remove the funnel, add 2-3 drops (25 [micro]L) of a 1 
gram/L resazurin dye stock solution. Cap the bottle with a butyl rubber 
stopper (Bellco Glass, Part 2048-11800) and crimp with an aluminum seal 
(Bellco Glass Part 2048-11020).
    c. Using a plastic tube with a (23-gauge, 1-inch long) needle 
attached to one side and a nitrogen source to the other, puncture the 
serum cap with the needle. Puncture the serum cap again with a second 
needle to sparge the bottle's headspace of residual air for two minutes. 
The nitrogen should be flowing at no more than 100 mL/min to encourage 
gentle displacement of oxygenated air with nitrogen. Faster nitrogen 
flow rates would cause mixing and complete oxygen removal would take 
much longer. Remove the nitrogen needle first to avoid any initial 
pressure problems. The second (vent) needle should be removed within 30 
seconds of removing the nitrogen needle.
    d. Triplicate blank test systems are prepared, with similar 
quantities of sediment and seawater without any base fluid. Incubate in 
the dark at a constant temperature of 29 1 [deg]C.
    e. Record the test temperature. The test duration is dependent on 
base fluid performance, but at a maximum should be no more than 275 
days. Stop the test after all base fluids have achieved a plateau of gas 
production. At termination, base fluid concentrations can be verified in 
the terminated samples by extraction and GC analysis according to 
Section 8.

            4.0. Concentration Verification Chemical Analyses

    a. Because of the difficulty of homogeneously mixing base fluid with 
sediment, it is important to demonstrate that the base fluid is evenly 
mixed within the sediment sea water slurry that was added to each 
bottle. Of the seven serum bottles set up for each test or control 
condition, three are randomly selected for concentration verification 
analyses. These should be immediately placed at 4 [deg]C and a sample of 
sediment from each bottle should be analyzed for base fluid content as 
soon as possible. The coefficient of variation (CV) for the replicate 
samples must be less than 20%. The results should show recovery of at 
least 70% of the spiked base fluid. Use an appropriate analytical 
procedure described in Section 8 to perform the extractions and 
analyses. If any set of sediments fail the criteria for concentration 
verification, then the corrective action for that set of sediments is 
also outlined in Section 8.
    b. The nominal concentrations and the measured concentrations from 
the three bottles selected for concentration verification should be 
reported for the initial test concentrations. The coefficient of 
variation (CV) for the replicate samples must be less than 20%. If base 
fluid content results are not within the 20% CV limit, the test must be 
stopped and restarted with adequately mixed sediment.

                     5.0. Gas Monitoring Procedures

    Biodegradation is measured by total gas as specified in ISO 
11734:1995. Methane production can also be tracked and is described in 
Section 7.

                  5.1. Total Gas Monitoring Procedures

    Bottles should be brought to room temperature before readings are 
taken. a. The bottles are observed to confirm that the resazurin has not 
oxidized to pink or blue. Total gas production in the culture bottles 
should be measured using a pressure transducer (one source is Biotech 
International). The pressure readings from test and control cultures are 
evaluated against a calibration curve created by analyzing the pressure 
created by known additions of gas to bottles established identically to 
the culture bottles. Bottles used for the standard curve contain 75 mL 
of water, and are sealed with the same rubber septa and crimp cap seals 
used for the bottles containing sediment. After the bottles used in the 
standard curve have been sealed, a syringe needle inserted through the 
septa is used to equilibrate the pressure inside the bottles to the 
outside atmosphere. The syringe needle is removed and known volumes of 
air are injected into the headspace of the bottles. Pressure readings 
provide a standard curve relating the volume of gas injected into the 
bottles and headspace pressure. No less than three points may be used to 
generate the standard curve. A typical standard curve may use 0, 1, 5, 
10, 20 and 40 mL of gas added to the standard curve bottles.
    b. The room temperature and barometric pressure (to two digits) 
should be recorded at the time of sampling. One option for the barometer 
is Fisher Part 02-400 or 02-401. Gas production by the sediment is 
expressed in terms of the volume (mL) of gas at standard temperature (0 
[deg]C = 273 [deg]K) and pressure (1 atm = 30 inches of Hg) using Eq. 
16.

[[Page 317]]

[GRAPHIC] [TIFF OMITTED] TR18MY12.020

Where:

V2 = Volume of gas production at standard temperature and 
          pressure
P1 = Barometric pressure on day of sampling (inches of Hg)
V1 = Volume of gas measured on day of sampling (mL)
T2 = Standard temperature = 273 [deg]K
T1 = Temperature on day of sampling ( [deg]C + 273 = [deg]K)
P2 = Standard pressure = 30 inches Hg

    c. An estimate can be made of the total volume of anaerobic gas that 
will be produced in the bottles. The gas production measured for each 
base fluid can be expressed as a percent of predicted total anaerobic 
gas production.
    5.1.1. Calculate the total amount of carbon in the form of the base 
fluid present in each bottle.
    a. Each bottle is to contain 30 g dry weight sediment. The base 
fluid concentration is 2,000 mg carbon/kg dry weight sediment. 
Therefore:
[GRAPHIC] [TIFF OMITTED] TR18MY12.021

    5.1.2. Theory states that anaerobic microorganisms will convert 1 
mole of carbon substrate into 1 mole of total anaerobic gas production.
    a. Calculate the number of moles of carbon in each bottle.
    b. The molecular weight of carbon is 12 (i.e., 1 mole of carbon = 12 
g). Therefore, the number of moles of carbon in each bottle can be 
calculated.
[GRAPHIC] [TIFF OMITTED] TR18MY12.022

    5.1.3. Calculate the predicted volume of anaerobic gas.
    One mole of gas equals 22.4 L (at standard temperature and 
pressure), therefore,
[GRAPHIC] [TIFF OMITTED] TR18MY12.023

                            5.2. Gas Venting

    a. If the pressure in the serum bottle is too great for the pressure 
transducer or syringe, some of the excess gas must be wasted. The best 
method to do this is to vent the excess gas right after measurement. To 
do this, remove the barrel from a 10-mL syringe and fill it \1/3\ full 
with water. This is then inserted into the bottle through the stopper 
using a small diameter (high gauge) needle. The excess pressure is 
allowed to vent through the water until the bubbles stop. This allows 
equalization of the pressure inside the bottle to atmospheric without 
introducing oxygen. The amount of gas vented (which is equal to the 
volume determined that day) must be kept track of each time the bottles 
are vented. A simple way to do this in a spreadsheet format is to have a 
separate column in which cumulative vented gas is tabulated. Each time 
the volume of gas in the cultures is analyzed, the total gas produced is 
equal to the gas in the culture at that time plus the total of the 
vented gas.
    b. To keep track of the methane lost in the venting procedure, 
multiply the amount of gas vented each time by the corrected % methane 
determined on that day. The answer gives the volume of methane wasted. 
This must be added into the cumulative totals similarly to the total gas 
additions.

               6.0. Test Acceptability and Interpretation

                         6.1. Test Acceptability

    At day 275 or when gas production has plateaued, whichever is first, 
the controls are evaluated to confirm that the test has been performed 
appropriately. In order for

[[Page 318]]

this modification of the closed bottle biodegradation test to be 
considered acceptable, all the controls must meet the biodegradation 
levels indicated in Table 1. The intermediate control hexadecene must 
produce at least 30% of the theoretical gas production. This level may 
be reexamined after two years and more data has been generated.

                                      Table 1--Test Acceptability Criteria

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

                           6.2 Interpretation

    a. In order for a fluid to pass the closed bottle test, the 
biodegradation of the base fluid as indicated by the total amount of 
total gas (or methane) generated once gas production has plateaued (or 
at the end of 275 days, which ever is first) must be greater than or 
equal to the volume of gas (or methane) produced by the reference 
standard (internal elefin or ester).
    b. The method for evaluating the data to determine whether a fluid 
has passed the biodegradation test must use the equations:
[GRAPHIC] [TIFF OMITTED] TR18MY12.024

Where:

NAF = Stock base fluid being tested for compliance
Reference fluid = C16-C18 internal olefin or 
          C12 -C14 or C8 ester 
          reference fluid

                        7.0. Methane Measurement

                   7.1. Methane Monitoring Procedures

    a. The use of total gas production alone may result in an 
underestimation of the actual metabolism occurring since CO2 
is slightly soluble in water. An acceptable alternative method is to 
monitor methane production and total gas production. This is easily done 
using GC analysis. A direct injection of headspace gases can be made 
into a GC using almost any packed or capillary column with an FID 
detector. Unless volatile fuels or solvents are present in the test 
material or the inocula, the only component of the headspace gas that 
can be detected using an FID detector is methane. The percent methane in 
the headspace gas is determined by comparing the response of the sample 
injections to the response from injections of known percent methane 
standards. The percent methane is corrected for water vapor saturation 
using Eq. 21 and then converted to a volume of dry methane using Eq. 22.
[GRAPHIC] [TIFF OMITTED] TR18MY12.025

Where:

D = The density of water vapor at saturation (g/m\3\, can be found in 
          CRC Handbook of Chemistry and Physics) for the temperature of 
          sampling.
          [GRAPHIC] [TIFF OMITTED] TR18MY12.026
          
Where:

VCH4 = Volume of methane in the bottle

[[Page 319]]

S = Volume of excess gas production (measured with a pressure 
          transducer)
V = Volume of the headspace in the culture bottle (total volume--liquid 
          phase)
P = Barometric pressure (mm Hg, measured with barometer)
T = Temperature ([deg]C)
Pw = Vapor pressure of water at T (mm Hg, can be found in CRC 
          Handbook of Chemistry and Physics)
CH4 = % methane in headspace gas (after correction for water 
          vapor)

    b. The total volume of serum bottles sold as 125 mL bottles 
(Wheaton) is 154.8 mL.
    c. The volumes of methane produced are then compared to the volumes 
of methane in the controls to determine if a significant inhibition of 
methane production or a significant increase of methane production has 
been observed. Effective statistical analyses are important, as 
variability in the results is common due to the heterogeneity of the 
inoculum's source. It is also common to observe that the timing of the 
initiation of culture activity is not equal in all of the cultures. 
Expect a great variability over the period when the cultures are active, 
some replicates will start sooner than others, but all of the replicates 
should eventually reach similar levels of base fluid degradation and 
methane production.

              7.2. Expected Methane Production Calculations

    a. The amount of methane expected can be calculated using the 
equation of Symons and Buswell (Eq. 23). In the case of complete 
mineralization, all of the carbon will appear as wither CO2 
or CH4, thus the total moles of gas produced will be equal to 
the total moles of carbon in the parent molecule. The use of the Buswell 
equation allows you to calculate the effects the redox potential will 
have on the distribution of the products in methanogenic cultures. More 
reduced electron donors will allow the production of more methane, while 
more oxidized electron donors will cause a production of more carbon 
dioxide.
[GRAPHIC] [TIFF OMITTED] TR18MY12.027

    b. An example calculation of the expected methane volume in a 
culture fed 2,000 mg/kg hexadecene is as follows. The application of 
Symons and Buswell's equation reveals that hexadecene 
(C16H32) will yield 4 moles of CO2 and 
12 moles of CH4. Assuming 30 g of dry sediment are added to 
the bottles with 2,334 mg hexadecene/kg dry sediment (i.e., equivalent 
to 2,000 mg carbon/kg dry sediment) the calculation is as follows.
[GRAPHIC] [TIFF OMITTED] TR18MY12.028

    c. By subtracting the average amount of methane in control bottles 
from the test bottles and then dividing by the expected volume an 
evaluation of the completion of the process may be conducted.

                8.0. Concentration Verification Analysis

    The Concentration Verification analysis is required at the beginning 
of the test to ensure homogeneity and confirm that the required amount 
of fluid was delivered to the sediments at the start of the test.
    8.1. Three samples per fluid need to be analyzed and achieve <=20% 
Coefficient of Variability and an average of =70% to <=120% 
of fluid delivered to sediment.
    8.2. If a third party performs the analysis, then the laboratory 
should be capable of delivering the homogeneity data within seven days, 
in order to identify any samples that do not meet the homogeneity 
requirement as quickly as possible.
    8.3. If one sediment/fluid set, out a multiple set batch of samples, 
fails these criteria, then that one set of samples must be discarded and 
a fresh set of spiked sediment prepared, started, and analyzed to ensure 
homogeneity. The same stock sediment is used to prepare the replacement 
set(s). The remaining sets do not need to be re-mixed or restarted.
    8.4. The re-mixed set(s) will need to be run the additional days as 
appropriate to ensure that the total number of days is the same for all 
sets of bottles, even though the specific days are not aligned.

[[Page 320]]

    8.5. Re-mixing of bottle sets can be performed multiple times as a 
result of a failure of the analytical criteria, until the holding time 
for the stock sediment has expired (60 days). If the problem set(s) has 
not fallen within the acceptable analytical criteria by then, it must 
not be part of the batch of bottles run. If the problem batch is one of 
the controls, and those controls were not successfully prepared when the 
sediment holding time expired, then the entire test must be restarted.

  Sec. Appendix 5 to Subpart A of Part 435--Determination of Crude Oil 
Contamination in Non-Aqueous Drilling Fluids by Gas Chromatography/Mass 
                 Spectrometry (GC/MS) (EPA Method 1655)

                        1.0 Scope and Application

    1.1 This method determines crude (formation) oil contamination, or 
other petroleum oil contamination, in non-aqueous drilling fluids (NAFs) 
by comparing the gas chromatography/mass spectrometry (GC/MS) 
fingerprint scan and extracted ion scans of the test sample to that of 
an uncontaminated sample.
    1.2 This method can be used for monitoring oil contamination of NAFs 
or monitoring oil contamination of the base fluid used in the NAF 
formulations.
    1.3 Any modification of this method beyond those expressly permitted 
shall be considered as a major modification subject to application and 
approval of alternative test procedures under 40 CFR 136.4 and 136.5.
    1.4 The gas chromatography/mass spectrometry portions of this method 
are restricted to use by, or under the supervision of analysts 
experienced in the use of GC/MS and in the interpretation of gas 
chromatograms and extracted ion scans. Each laboratory that uses this 
method must generate acceptable results using the procedures described 
in Sections 7, 9.2, and 12 of this appendix.

                          2.0 Summary of Method

    2.1 Analysis of NAF for crude oil contamination is a step-wise 
process. The analyst first performs a qualitative assessment of the 
presence or absence of crude oil in the sample. If crude oil is detected 
during this qualitative assessment, the analyst must perform a 
quantitative analysis of the crude oil concentration.
    2.2 A sample of NAF is centrifuged to obtain a solids free 
supernate.
    2.3 The test sample is prepared by removing an aliquot of the solids 
free supernate, spiking it with internal standard, and analyzing it 
using GC/MS techniques. The components are separated by the gas 
chromatograph and detected by the mass spectrometer.
    2.4 Qualitative identification of crude oil contamination is 
performed by comparing the Total Ion Chromatograph (TIC) scans and 
Extracted Ion Profile (EIP) scans of test sample to that of 
uncontaminated base fluids, and examining the profiles for 
chromatographic signatures diagnostic of oil contamination.
    2.5 The presence or absence of crude oil contamination observed in 
the full scan profiles and selected extracted ion profiles determines 
further sample quantitation and reporting requirements.
    2.6 If crude oil is detected in the qualitative analysis, 
quantitative analysis must be performed by calibrating the GC/MS using a 
designated NAF spiked with known concentrations of a designated oil.
    2.7 Quality is assured through reproducible calibration and testing 
of GC/MS system and through analysis of quality control samples.

                             3.0 Definitions

    3.1 A NAF is one in which the continuous--phase is a water 
immiscible fluid such as an oleaginous material (e.g., mineral oil,

[[Page 322]]

enhance mineral oil, paraffinic oil, or synthetic material such as 
olefins and vegetable esters).
    3.2 TIC--Total Ion Chromatograph.
    3.3 EIP--Extracted Ion Profile.
    3.4 TCB--1,3,5-trichlorobenzene is used as the internal standard in 
this method.
    3.5 SPTM--System Performance Test Mix standards are used to 
establish retention times and monitor detection levels.

                    4.0 Interferences and Limitations

    4.1 Solvents, reagents, glassware, and other sample processing 
hardware may yield artifacts and/or elevated baselines causing 
misinterpretation of chromatograms.
    4.2 All Materials used in the analysis shall be demonstrated to be 
free from interferences by running method blanks. Specific selection of 
reagents and purification of solvents by distillation in all-glass 
systems may be required.
    4.3 Glassware shall be cleaned by rinsing with solvent and baking at 
400 [deg]C for a minimum of 1 hour.
    4.4 Interferences may vary from source to source, depending on the 
diversity of the samples being tested.
    4.5 Variations in and additions of base fluids and/or drilling fluid 
additives (emulsifiers, dispersants, fluid loss control agents, etc.) 
might also cause interferences and misinterpretation of chromatograms.
    4.6 Difference in light crude oils, medium crude oils, and heavy 
crude oils will result in different responses and thus different 
interpretation of scans and calculated percentages.

                               5.0 Safety

    5.1 The toxicity or carcinogenicity of each reagent used in this 
method has not been precisely determined; however each chemical shall be 
treated as a potential health hazard. Exposure to these chemicals should 
be reduced to the lowest possible level.
    5.2 Unknown samples may contain high concentration of volatile toxic 
compounds. Sample containers should be opened in a hood and handled with 
gloves to prevent exposure. In addition, all sample preparation should 
be conducted in a fume hood to limit the potential exposure to harmful 
contaminates.
    5.3 This method does not address all safety issues associated with 
its use. The laboratory is responsible for maintaining a safe work 
environment and a current awareness file of OSHA regulations regarding 
the safe handling of the chemicals specified in this method. A reference 
file of material safety data sheets (MSDSs) shall be available to all 
personnel involved in these analyses. Additional references to 
laboratory safety can be found in References 16.1 through 16.3.
    5.4 NAF base fluids may cause skin irritation, protective gloves are 
recommended while handling these samples.

                       7.0 Reagents and Standards

    7.1 Methylene chloride--Pesticide grade or equivalent. Use when 
necessary for sample dilution.
    7.2 Standards--Prepare from pure individual standard materials or 
purchase as certified solutions. If compound purity is 96% or greater, 
the weight may be used without correction to compute the concentration 
of the standard.
    7.2.1 Crude Oil Reference--Obtain a sample of a crude oil with a 
known API gravity. This oil shall be used in the calibration procedures.
    7.2.2 Synthetic Base Fluid--Obtain a sample of clean internal olefin 
(IO) Lab drilling fluid (as sent from the supplier--has not been 
circulated downhole). This drilling fluid shall be used in the 
calibration procedures.
    7.2.3 Internal standard--Prepare a 0.01 g/mL solution of 1,3,5-
trichlorobenzene (TCB). Dissolve 1.0 g of TCB in methylene chloride and 
dilute to volume in a 100-mL volumetric flask. Stopper, vortex, and 
transfer the solution to a 150-mL bottle with PTFE-lined cap. Label 
appropriately, and store at -5 [deg]C to 20 [deg]C. Mark the level of 
the meniscus on the bottle to detect solvent loss.
    7.2.4 GC/MS system performance test mix (SPTM) standards--The SPTM

No. 4-7300). Prepare a high concentration of the SPTM standard at 62.5 
mg/mL in methylene chloride. Prepare a medium concentration SPTM 
standard at 1.25 mg/mL by transferring 1.0 mL of the 62.5 mg/mL solution 
into a 50 mL volumetric flask and diluting to the mark with methylene 
chloride. Finally, prepare a low concentration SPTM standard at 0.125 
mg/mL by transferring 1.0 mL of the 1.25 mg/mL solution into a 10-mL 
volumetric flask and diluting to the mark with methylene chloride.
    7.2.5 Crude oil/drilling fluid calibration standards--Prepare a 4-
point crude oil/drilling fluid calibration at concentrations of 0% (no 
spike--clean drilling fluid), 0.5%, 1.0%, and 2.0% by weight according 
to the procedures outlined in this appendix using the Reference Crude 
Oil:
    7.2.5.1 Label 4 jars with the following identification: Jar 1--
0%Ref-IOLab, Jar 2--0.5%Ref-IOLab, Jar 3--1%Ref-IOLab, and Jar 4--2%Ref-
IOLab.
    7.2.5.2 Weigh 4, 50-g aliquots of well mixed IO Lab drilling fluid 
into each of the 4 jars.
    7.2.5.3 Add Reference Oil at 0.5%, 1.0%, and 2.0% by weight to jars 
2, 3, and 4 respectively. Jar 1 shall not be spiked with Reference Oil 
in order to retain a ``0%'' oil concentration.
    7.2.5.4 Thoroughly mix the contents of each of the 4 jars, using 
clean glass stirring rods.
    7.2.5.5 Transfer (weigh) a 30-g aliquot from Jar 1 to a labeled 
centrifuge tube. Centrifuge the aliquot for a minimum of 15 min at 
approximately 15,000 rpm, in order to obtain a solids free supernate. 
Weigh 0.5 g of the supernate directly into a tared and appropriately 
labeled GC straight vial. Spike the 0.5-g supernate with 500 [micro]L of 
the 0.01g/mL 1,3,5-trichlorobenzene internal standard solution (see 
Section 7.2.3 of this appendix), cap with a Teflon lined crimp cap, and 
vortex for ca. 10 sec.
    7.2.5.6 Repeat step 7.2.5.5 except use an aliquot from Jar 2.
    7.2.5.7 Repeat step 7.2.5.5 except use an aliquot from Jar 3.
    7.2.5.8 Repeat step 7.2.5.5 except use an aliquot from Jar 4.
    7.2.5.9 These 4 crude/oil drilling fluid calibration standards are 
now used for qualitative and quantitative GC/MS analysis.
    7.2.6 Precision and recovery standard (mid level crude oil/drilling 
fluid calibration standard)--Prepare a mid point crude oil/ drilling 
fluid calibration using IO Lab drilling fluid and Reference Oil at a 
concentration of 1.0% by weight. Prepare this standard according to the 
procedures outlined in Section 7.2.5.1 through 7.2.5.5 of this appendix, 
with the exception that only ``Jar 3'' needs to be prepared. Remove and 
spike with internal standard, as many 0.5-g aliquots as needed to 
complete the GC/MS analysis (see Section 11.6 of this appendix--
bracketing authentic samples every 12 hours with precision and recovery 
standard) and the initial demonstration exercise described in Section 
9.2 of this appendix.
    7.2.7 Stability of standards
    7.2.7.1 When not used, standards shall be stored in the dark, at -5 
to -20 [deg]C in screw-capped vials with PTFE-lined lids. Place a mark 
on the vial at the level of the solution so that solvent loss by 
evaporation can be detected. Bring the vial to room temperature prior to 
use.

[[Page 324]]

    7.2.7.2 Solutions used for quantitative purposes shall be analyzed 
within 48 hours of preparation and on a monthly basis thereafter for 
signs of degradation. A standard shall remain acceptable if the peak 
area remains within 15% of the area obtained in 
the initial analysis of the standard.

             8.0 Sample Collection Preservation and Storage

    8.1 Collect NAF and base fluid samples in 100- to 200-mL glass 
bottles with PTFE- or aluminum foil lined caps.
    8.2 Samples collected in the field shall be stored refrigerated 
until time of preparation.
    8.3 Sample and extract holding times for this method have not yet 
been established. However, based on initial experience with the method, 
samples should be analyzed within seven to ten days of collection and 
extracts should be analyzed within seven days of preparation.
    8.4 After completion of GC/MS analysis, extracts shall be 
refrigerated at 4 [deg]C until further notification of sample disposal.

                           9.0 Quality Control

    9.1 Each laboratory that uses this method is required to operate a 
formal quality assurance program (Reference 16.4). The minimum 
requirements of this program shall consist of an initial demonstration 
of laboratory capability, and ongoing analysis of standards, and blanks 
as a test of continued performance, analyses of spiked samples to assess 
accuracy and analysis of duplicates to assess precision. Laboratory 
performance shall be compared to established performance criteria to 
determine if the results of analyses meet the performance 
characteristics of the method.
    9.1.1 The analyst shall make an initial demonstration of the ability 
to generate acceptable accuracy and precision with this method. This 
ability shall be established as described in Section 9.2 of this 
appendix.
    9.1.2 The analyst is permitted to modify this method to improve 
separations or lower the cost of measurements, provided all performance 
requirements are met. Each time a modification is made to the method, 
the analyst is required to repeat the calibration (Section 10.4 of this 
appendix) and to repeat the initial demonstration procedure described in 
Section 9.2 of this appendix.
    9.1.3 Analyses of blanks are required to demonstrate freedom from 
contamination. The procedures and criteria for analysis of a blank are 
described in Section 9.3 of this appendix.
    9.1.4 Analysis of a matrix spike sample is required to demonstrate 
method accuracy. The procedure and QC criteria for spiking are described 
in Section 9.4 of this appendix.
    9.1.5 Analysis of a duplicate field sample is required to 
demonstrate method precision. The procedure and QC criteria for 
duplicates are described in Section 9.5 of this appendix.
    9.1.6 Analysis of a sample of the clean NAF(s) (as sent from the 
supplier--i.e., has not been circulated downhole) used in the drilling 
operations is required.
    9.1.7 The laboratory shall, on an ongoing basis, demonstrate through 
calibration verification and the analysis of the precision and recovery 
standard (Section 7.2.6 of this appendix) that the analysis system is in 
control. These procedures are described in Section 11.6 of this 
appendix.
    9.1.8 The laboratory shall maintain records to define the quality of 
data that is generated.
    9.2 Initial precision and accuracy--The initial precision and 
recovery test shall be performed using the precision and recovery 
standard (1% by weight Reference Oil in IO Lab drilling fluid). The 
laboratory shall generate acceptable precision and recovery by 
performing the following operations.
    9.2.1 Prepare four separate aliquots of the precision and recovery 
standard using the procedure outlined in Section 7.2.6 of this appendix. 
Analyze these aliquots using the procedures outlined in Section 11 of 
this appendix.
    9.2.2 Using the results of the set of four analyses, compute the 
average recovery (X) in weight percent and the standard deviation of the 
recovery(s) for each sample.
    9.2.3 If s and X meet the acceptance criteria of 80% to 110%, system 
performance is acceptable and analysis of samples may begin. If, 
however, s exceeds the precision limit or X falls outside the range for 
accuracy, system performance is unacceptable. In this event, review this 
method, correct the problem, and repeat the test.
    9.2.4 Accuracy and precision--The average percent recovery (P) and 
the standard deviation of the percent recovery (Sp) Express the accuracy 
assessment as a percent recovery interval from P-2Sp to P + 
2Sp. For example, if P = 90% and Sp = 10% for four 
analyses of crude oil in NAF, the accuracy interval is expressed as 70% 
to 110%. Update the accuracy assessment on a regular basis.
    9.3 Blanks--Rinse glassware and centrifuge tubes used in the method 
with 30 mL of methylene chloride, remove a 0.5-g aliquot of the solvent, 
spike it with the 500 [micro]L of the internal standard solution 
(Section 7.2.3 of this appendix) and analyze a 1-[micro]L aliquot of the 
blank sample using the procedure in Section 11 of this appendix. Compute 
results per Section 12 of this appendix.
    9.4 Matrix spike sample--Prepare a matrix spike sample according to 
procedure outlined in Section 7.2.6 of this appendix. Analyze the sample 
and calculate the concentration (% oil) in the drilling fluid and % 
recovery of oil from the spiked drilling fluid using the methods 
described in Sections 11 and 12 of this appendix.

[[Page 325]]

    9.5 Duplicates--A duplicate field sample shall be prepared and 
analyzed according to Section 11. The relative percent difference (RPD) 
of the calculated concentrations shall be less than 15%.
    9.5.1 Analyze each of the duplicates per the procedure in Section 11 
of this appendix and compute the results per Section 12 of this 
appendix.
    9.5.2 Calculate the relative percent difference (RPD) between the 
two results per the following equation:
[GRAPHIC] [TIFF OMITTED] TR18MY12.029

where:

D1 = Concentration of crude oil in the sample; and
D2 = Concentration of crude oil in the duplicate sample.

    9.5.3 If the RPD criteria are not met, the analytical system shall 
be judged to be out of control, and the problem must be immediately 
identified and corrected, and the sample batch re-analyzed.
    9.6 A clean NAF sample shall be prepared and analyzed according to 
Section 11. Ultimately the oil-equivalent concentration from the TIC or 
EIP signal measured in the clean NAF sample shall be subtracted from the 
corresponding authentic field samples in order to calculate the true 
contaminant concentration (% oil) in the field samples (see Section 12).
    9.7 The specifications contained in this method can be met if the 
apparatus used is calibrated properly, and maintained in a calibrated 
state. The standards used for initial precision and recovery (Section 
9.2 of this appendix) and ongoing precision and recovery (Section 11.6 
of this appendix) shall be identical, so that the most precise results 
will be obtained. The GC/MS instrument will provide the most 
reproducible results if dedicated to the setting and conditions required 
for the analyses given in this method.
    9.8 Depending on specific program requirements, field replicates and 
field spikes of crude oil into samples may be required when this method 
is used to assess the precision and accuracy of the sampling and sample 
transporting techniques.

                            10.0 Calibration

    10.1 Establish gas chromatographic/mass spectrometer operating 
conditions given in Table 1 of this appendix. Perform the GC/MS system 
hardware-tune as outlined by the manufacture. The gas chromatograph 
shall be calibrated using the internal standard technique.
    Note: Because each GC is slightly different, it may be necessary to 
adjust the operating conditions (carrier gas flow rate and column 
temperature and temperature program) slightly until the retention times 
in Table 2 of this appendix are met.

    10.3.1 Spike a 500-mL aliquot of the 1.25 mg/mL SPTM standard with 
500 [micro]L of the TCB internal standard solution.
    10.3.2 Inject 1.0 [micro]L of this spiked SPTM standard onto the GC/
MS in order to demonstrate proper retention times. For the GC/MS used in 
the development of this method, the ten compounds in the mixture had 
typical retention times shown in Table 2 of this appendix. Extracted ion 
scans for m/z 91 and 105 showed a maximum abundance of 400,000.
    10.3.3 Spike a 500-mL aliquot of the 0.125 mg/mL SPTM standard with 
500 [micro]L of the TCB internal standard solution.

[[Page 326]]

    10.3.4 Inject 1.0 [micro]L of this spiked SPTM standard onto the GC/
MS to monitor detectable levels. For the GC/MS used in the development 
of this test, all ten compounds showed a minimum peak height of three 
times signal to noise. Extracted ion scans for m/z 91 and 105 showed a 
maximum abundance of 40,000.
    10.4 GC/MS crude oil/drilling fluid calibration--There are two 
methods of quantification: Total Area Integration (C8-
C13) and EIP Area Integration using m/z's 91 and 105. The 
Total Area Integration method should be used as the primary technique 
for quantifying crude oil in NAFs. The EIP Area Integration method 
should be used as a confirmatory technique for NAFs. However, the EIP 
Area Integration method shall be used as the primary method for 
quantifying oil in enhanced mineral oil (EMO) based drilling fluid. 
Inject 1.0 [micro]L of each of the four crude oil/drilling fluid 
calibration standards prepared in Section 7.2.5 of this appendix into 
the GC/MS. The internal standard should elute approximately 21-22 
minutes after injection. For the GC/MS used in the development of this 
method, the internal standard peak was (35 to 40)% of full scale at an 
abundance of about 3.5e + 07.
    10.4.1 Total Area Integration Method--For each of the four 
calibration standards obtain the following: Using a straight baseline 
integration technique, obtain the total ion chromatogram (TIC) area from 
C8 to C13. Obtain the TIC area of the internal 
standard (TCB). Subtract the TCB area from the C8-
C13 area to obtain the true C8-C13 
area. Using the C8-C13 and TCB areas, and known 
internal standard concentration, generate a linear regression 
calibration using the internal standard method. The r\2\ value for the 
linear regression curve shall be greater than or equal to 0.998. Some 
synthetic fluids might have peaks that elute in the window and would 
interfere with the analysis. In this case the integration window can be 
shifted to other areas of scan where there are no interfering peaks from 
the synthetic base fluid.
    10.4.2 EIP Area Integration--For each of the four calibration 
standards generate Extracted Ion Profiles (EIPs) for m/z 91 and 105. 
Using straight baseline integration techniques, obtain the following EIP 
areas:
    10.4.2.1 For m/z 91 integrate the area under the curve from 
approximately 9 minutes to 21-22 minutes, just prior to but not 
including the internal standard.
    10.4.2.2 For m/z 105 integrate the area under the curve from 
approximately 10.5 minutes to 26.5 minutes.
    10.4.2.3 Obtain the internal standard area from the TCB in each of 
the four calibration standards, using m/z 180.
    10.4.2.4 Using the EIP areas for TCB, m/z 91 and m/z105, and the 
known concentration of internal standard, generate linear regression 
calibration curves for the target ions 91 and 105 using the internal 
standard method. The r\2\ value for each of the EIP linear regression 
curves shall be greater than or equal to 0.998.
    10.4.2.5 Some base fluids might produce a background level that 
would show up on the extracted ion profiles, but there should not be any 
real peaks (signal to noise ratio of 1:3) from the clean base fluids.

                             11.0 Procedure

    11.1 Sample Preparation--
    11.1.1 Mix the authentic field sample (drilling fluid) well. 
Transfer (weigh) a 30-g aliquot of the sample to a labeled centrifuge 
tube.
    11.1.2 Centrifuge the aliquot for a minimum of 15 min at 
approximately 15,000 rpm, in order to obtain a solids free supernate.
    11.1.3 Weigh 0.5 g of the supernate directly into a tared and 
appropriately labeled GC straight vial.
    11.1.4 Spike the 0.5-g supernate with 500 [micro]L of the 0.01g/mL 
1,3,5-trichlorobenzene internal standard solution (see Section 7.2.3 of 
this appendix), cap with a Teflon lined crimp cap, and vortex for ca. 10 
sec.
    11.1.5 The sample is ready for GC/MS analysis.
    11.2 Gas Chromatography.
    Table 1 of this appendix summarizes the recommended operating 
conditions for the GC/MS. Retention times for the n-alkanes obtained 
under these conditions are given in Table 2 of this appendix. Other 
columns, chromatographic conditions, or detectors may be used if initial 
precision and accuracy requirements (Section 9.2 of this appendix) are 
met. The system shall be calibrated according to the procedures outlined 
in Section 10 of this appendix, and verified every 12 hours according to 
Section 11.6 of this appendix.
    11.2.1 Samples shall be prepared (extracted) in a batch of no more 
than 20 samples. The batch shall consist of 20 authentic samples, 1 
blank (Section 9.3 of this appendix), 1 matrix spike sample (9.4), and 1 
duplicate field sample (9.5), and a prepared sample of the corresponding 
clean NAF used in the drilling process.
    11.2.2 An analytical sequence shall be analyzed on the GC/MS where 
the 3 SPTM standards (Section 7.2.4 of this appendix) containing 
internal standard are analyzed first, followed by analysis of the four 
GC/MS crude oil/drilling fluid calibration standards (Section 7.2.5 of 
this appendix), analysis of the blank, matrix spike sample, the 
duplicate sample, the clean NAF sample, followed by the authentic 
samples.
    11.2.3 Samples requiring dilution due to excessive signal shall be 
diluted using methylene chloride.

[[Page 327]]

    11.2.4 Inject 1.0 [micro]L of the test sample or standard into the 
GC, using the conditions in Table 1 of this appendix.
    11.2.5 Begin data collection and the temperature program at the time 
of injection.
    11.2.6 Obtain a TIC and EIP fingerprint scans of the sample (Table 3 
of this appendix).
    11.2.7 If the area of the C8 to C13 peaks 
exceeds the calibration range of the system, dilute a fresh aliquot of 
the test sample weighing 0.50-g and re-analyze.
    11.2.8 Determine the C8 to C13 TIC area, the 
TCB internal standard area, and the areas for the m/z 91 and 105 EIPs. 
These shall be used in the calculation of oil concentration in the 
samples (see Section 12 of this appendix).

    11.2.9 Observe the presence of peaks in the EIPs that would confirm 
the presence of any target aromatic compounds. Using the EIP areas and 
EIP linear regression calibrations compare the abundance of the aromatic 
peaks, and if appropriate, determine approximate crude oil contamination 
in the sample for each of the target ions.
    11.3 Qualitative Identification--See Section 17 of this method for 
schematic flowchart.
    11.3.1 Qualitative identification shall be accomplished by 
comparison of the TIC and EIP area data from an authentic sample to the 
TIC and EIP area data from the calibration standards (see Section 10.4). 
Crude oil shall be identified by the presence of C10 to 
C13 n-alkanes and corresponding target aromatics.
    11.3.2 Using the calibration data, establish the identity of the 
C8 to C13 peaks in the chromatogram of the sample. 
Using the calibration data, establish the identity of any target 
aromatics present on the extracted ion scans.
    11.3.3 Crude oil is not present in a detectable amount in the sample 
if there are no target aromatics seen on the extracted ion scans. The 
experience of the analyst shall weigh heavily in the determination of 
the presence of peaks at a signal-to-noise ratio of 3 or greater.
    11.3.4 If the chromatogram shows n-alkanes from C8 to 
C13 and target aromatics to be present, contamination by 
crude oil or diesel shall be suspected and quantitative analysis shall 
be determined. If there are no n-alkanes present that are not seen on 
the blank, and no target aromatics are seen, the sample can be 
considered to be free of contamination.
    11.4 Quantitative Identification--
    11.4.1 Determine the area of the peaks from C8 to 
C13 as outlined in the calibration section (10.4.1 of this 
appendix). If the area of the peaks for the sample is greater than that 
for the clean NAF (base fluid) use the crude oil/drilling fluid 
calibration TIC linear regression curve to determine approximate crude 
oil contamination.
    11.4.2 Using the EIPs outlined in Section 10.4.2 of this appendix, 
determine the presence of any target aromatics. Using the integration 
techniques outlined in Section 10.4.2 of this appendix, obtain the EIP 
areas for m/z 91 and 105. Use the crude oil/drilling fluid calibration 
EIP linear regression curves to determine approximate crude oil 
contamination.
    11.5 Complex Samples--
    11.5.1 The most common interferences in the determination of crude 
oil can be from mineral oil, diesel oil, and proprietary additives in 
drilling fluids.
    11.5.2 Mineral oil can typically be identified by its lower target 
aromatic content, and narrow range of strong peaks.
    11.5.3 Diesel oil can typically be identified by low amounts of n-
alkanes from C7 to C9, and the absence of n-
alkanes greater than C25.
    11.5.4 Crude oils can usually be distinguished by the presence of 
high aromatics, increased intensities of C8 to C13 
peaks, and/ or the presence of higher hydrocarbons of C25 and 
greater (which may be difficult to see in some synthetic fluids at low 
contamination levels).
    11.5.4.1 Oil condensates from gas wells are low in molecular weight 
and will normally produce strong chromatographic peaks in the 
C8-C13 range. If a sample of the gas condensate 
crude oil from the formation is available, the oil can be distinguished 
from other potential sources of contamination by using it to prepare a 
calibration standard.
    11.5.4.2 Asphaltene crude oils with API gravity <20 may not produce 
chromatographic peaks strong enough to show contamination at levels of 
the calibration. Extracted ion peaks should be easier to see than 
increased intensities for the C8 to C13 peaks. If a sample of asphaltene 
crude from the formation is available, a calibration standard shall be 
prepared.
    11.6 System and Laboratory Performance--
    11.6.1 At the beginning of each 8-hour shift during which analyses 
are performed,

[[Page 328]]

GC crude oil/drilling fluid calibration and system performance test 
mixes shall be verified. For these tests, analysis of the medium-level 
calibration standard (1-% Reference Oil in IO Lab drilling fluid, and 
1.25 mg/mL SPTM with internal standard) shall be used to verify all 
performance criteria. Adjustments and/or re-calibration (per Section 10 
of this appendix) shall be performed until all performance criteria are 
met. Only after all performance criteria are met may samples and blanks 
be analyzed.
    11.6.2 Inject 1.0 [micro]L of the medium-level GC/MS crude oil/
drilling fluid calibration standard into the GC instrument according to 
the procedures in Section 11.2 of this appendix. Verify that the linear 
regression curves for both TIC area and EIP areas are still valid using 
this continuing calibration standard.
    11.6.3 After this analysis is complete, inject 1.0 [micro]L of the 
1.25 mg/mL SPTM (containing internal standard) into the GC instrument 
and verify the proper retention times are met (see Table 2 of this 
appendix).
    11.6.4 Retention times--Retention time of the internal standard. The 
absolute retention time of the TCB internal standard shall be within the 
range 21.0 0.5 minutes. Relative retention times 
of the n-alkanes: The retention times of the n-alkanes relative to the 
TCB internal standard shall be similar to those given in Table 2 of this 
appendix.

                            12.0 Calculations

    The concentration of oil in NAFs drilling fluids shall be computed 
relative to peak areas between C8 and C13 (using 
the Total Area Integration method) or total peak areas from extracted 
ion profiles (using the Extracted Ion Profile Method). In either case, 
there is a measurable amount of peak area, even in clean drilling fluid 
samples, due to spurious peaks and electrometer ``noise'' that 
contributes to the total signal measured using either of the 
quantification methods. In this procedure, a correction for this signal 
is applied, using the blank or clean sample correction technique 
described in American Society for Testing Materials (ASTM) Method D-
3328-90, Comparison of Waterborne Oil by Gas Chromatography. In

[[Page 330]]

this method, the ``oil equivalents'' measured in a blank sample by total 
area gas chromatography are subtracted from that determined for a field 
sample to arrive at the most accurate measure of oil residue in the 
authentic sample.
    12.1 Total Area Integration Method
    12.1.1 Using C8 to C13 TIC area, the TCB area 
in the clean NAF sample and the TIC linear regression curve, compute the 
oil equivalent concentration of the C8 to C13 
retention time range in the clean NAF.
    Note: The actual TIC area of the C8 to C13 is 
equal to the C8 to C13 area minus the area of the 
TCB.
    12.1.2 Using the corresponding information for the authentic sample, 
compute the oil equivalent concentration of the C8 to 
C13 retention time range in the authentic sample.
    12.1.3 Calculate the concentration (% oil) of oil in the sample by 
subtracting the oil equivalent concentration (% oil) found in the clean 
NAF from the oil equivalent concentration (% oil) found in the authentic 
sample.
    12.2 EIP Area Integration Method
    12.2.1 Using either m/z 91 or 105 EIP areas, the TCB area in the 
clean NAF sample, and the appropriate EIP linear regression curve, 
compute the oil equivalent concentration of the in the clean NAF.
    12.2.2 Using the corresponding information for the authentic sample, 
compute its oil equivalent concentration.
    12.2.3 Calculate the concentration (% oil) of oil in the sample by 
subtracting the oil equivalent concentration (% oil) found in the clean 
NAF from the oil equivalent concentration (% oil) found in the authentic 
sample.

                         13.0 Method Performance

    13.1 Specification in this method are adopted from EPA Method 1663, 
Differentiation of Diesel and Crude Oil by GC/FID (Reference 16.5).
    13.2 Single laboratory method performance using an Internal Olefin 
(IO) drilling fluid fortified at 0.5% oil using a 35 API gravity oil 
was:

Precision and accuracy 94 4%
Accuracy interval--86.3% to 102%
Relative percent difference in duplicate analysis--6.2%

                        14.0 Pollution Prevention

    14.1 The solvent used in this method poses little threat to the 
environment when recycled and managed properly.

                          15.0 Waste Management

    15.1 It is the laboratory's responsibility to comply with all 
federal, state, and local regulations governing waste management, 
particularly the hazardous waste identification rules and land disposal 
restriction, and to protect the air, water, and land by minimizing and 
controlling all releases from fume hoods and bench operations. 
Compliance with all sewage discharge permits and regulations is also 
required.
    15.2 All authentic samples (drilling fluids) failing the RPE 
(fluorescence) test (indicated by the presence of fluorescence) shall be 
retained and classified as contaminated samples. Treatment and ultimate 
fate of these samples is not outlined in this SOP.

Method for Detection of Oil Contamination in Non-Aqueous Drilling Fluids 
                     (NAF) (GC/MS) (EPA Method 1670)

                        1.0 Scope and Application

    1.1 This method is used for determination of crude or formation oil, 
or other petroleum oil contamination, in non-aqueous drilling fluids 
(NAFs).
    1.2 This method is intended as a positive/negative test to determine 
a presence of crude oil in NAF prior to discharging drill cuttings from 
offshore production platforms.

[[Page 331]]

    1.3 This method is for use in the Environmental Protection Agency's 
(EPA's) survey and monitoring programs under the Clean Water Act, 
including monitoring of compliance with the Gulf of Mexico NPDES General 
Permit for monitoring of oil contamination in drilling fluids.
    1.4 This method has been designed to show positive contamination for 
5% of representative crude oils at a concentration of 0.1% in drilling 
fluid (vol/vol), 50% of representative crude oils at a concentration of 
0.5%, and 95% of representative crude oils at a concentration of 1%.
    1.5 Any modification of this method, beyond those expressly 
permitted, shall be considered a major modification subject to 
application and approval of alternate test procedures under 40 CFR parts 
136.4 and 136.5.
    1.6 Each laboratory that uses this method must demonstrate the 
ability to generate acceptable results using the procedure in Section 
9.2 of this appendix.

                          2.0 Summary of Method

    2.1 An aliquot of drilling fluid is extracted using isopropyl 
alcohol.
    2.2 The mixture is allowed to settle and then filtered to separate 
out residual solids.
    2.3 An aliquot of the filtered extract is charged onto a reverse 
phase extraction (RPE) cartridge.
    2.4 The cartridge is eluted with isopropyl alcohol.
    2.5 Crude oil contaminates are retained on the cartridge and their 
presence (or absence) is detected based on observed fluorescence using a 
black light.

                             3.0 Definitions

    3.1 A NAF is one in which the continuous phase is a water immiscible 
fluid such as an oleaginous material (e.g., mineral oil, enhance mineral 
oil, paraffinic oil, or synthetic material such as olefins and vegetable 
esters).

                            4.0 Interferences

    4.1 Solvents, reagents, glassware, and other sample-processing 
hardware may yield artifacts that affect results. Specific selection of 
reagents and purification of solvents may be required.
    4.2 All materials used in the analysis shall be demonstrated to be 
free from interferences under the conditions of analysis by running 
laboratory reagent blanks as described in Section 9.5 of this appendix.

                               5.0 Safety

    5.1 The toxicity or carcinogenicity of each reagent used in this 
method has not been precisely determined; however, each chemical shall 
be treated as a potential health hazard. Exposure to these chemicals 
should be reduced to the lowest possible level. Material Safety Data 
Sheets (MSDSs) shall be available for all reagents.
    5.2 Isopropyl alcohol is flammable and should be used in a well-
ventilated area.
    5.3 Unknown samples may contain high concentration of volatile toxic 
compounds. Sample containers should be opened in a hood and handled with 
gloves to prevent exposure. In addition, all sample preparation should 
be conducted in a well-ventilated area to limit the potential exposure 
to harmful contaminants. Drilling fluid samples should be handled with 
the same precautions used in the drilling fluid handling areas of the 
drilling rig.
    5.4 This method does not address all safety issues associated with 
its use. The laboratory is responsible for maintaining a safe work 
environment and a current awareness file of OSHA regulations regarding 
the safe handling of the chemicals specified in this method. A reference 
file of material safety data sheets (MSDSs) shall be available to all 
personnel involved in these analyses. Additional information on 
laboratory safety can be found in References 16.1-16.2.

7.5 x 7.5 in size and painted flat black inside. 
Lamp positioned in fitted and sealed slot in center on top of box. 
Sample cartridges sit in a tray, ca. 6 from lamp. Cardboard 
flaps cut on top panel and side of front panel for sample viewing and 
sample cartridge introduction, respectively.
    6.4.3 Viewing platform for cartridges. Simple support (hand made 
vial tray--black in color) for cartridges so that they do not move 
during the fluorescence testing.

                       7.0 Reagents and Standards

    7.1 Isopropyl alcohol--99% purity.
    7.2 NAF--Appropriate NAF as sent from the supplier (has not been 
circulated downhole). Use the clean NAF corresponding to the NAF being 
used in the current drilling operation.
    7.3 Standard crude oil--NIST SRM 1582 petroleum crude oil.

            8.0 Sample Collection, Preservation, and Storage

    8.1 Collect approximately one liter of representative sample (NAF, 
which has been circulated downhole) in a glass bottle or jar. Cover with 
a Teflon lined cap. To allow for a potential need to re-analyze and/or 
re-process the sample, it is recommended that a second sample aliquot be 
collected.
    8.2 Label the sample appropriately.
    8.3 All samples must be refrigerated at 0-4 [deg]C from the time of 
collection until extraction (40 CFR part 136, Table II).
    8.4 All samples must be analyzed within 28 days of the date and time 
of collection (40 CFR part 136, Table II).

                           9.0 Quality Control

    9.1 Each laboratory that uses this method is required to operate a 
formal quality assurance program (Reference 16.3). The minimum 
requirements of this program consist of an initial demonstration of 
laboratory capability, and ongoing analyses of blanks and spiked 
duplicates to assess accuracy and precision and to demonstrate continued 
performance. Each field sample is analyzed in duplicate to demonstrate 
representativeness.
    9.1.1 The analyst shall make an initial demonstration of the ability 
to generate acceptable accuracy and precision with this method. This 
ability is established as described in Section 9.2 of this appendix.
    9.1.2 Preparation and analysis of a set of spiked duplicate samples 
to document accuracy and precision. The procedure for the preparation 
and analysis of these samples is described in Section 9.4 of this 
appendix.
    9.1.3 Analyses of laboratory reagent blanks are required to 
demonstrate freedom from contamination. The procedure and criteria for 
preparation and analysis of a reagent blank are described in Section 9.5 
of this appendix.
    9.1.4 The laboratory shall maintain records to define the quality of 
the data that is generated.
    9.1.5 Accompanying QC for the determination of oil in NAF is 
required per analytical batch. An analytical batch is a set of samples 
extracted at the same time, to a maximum of 10 samples. Each analytical 
batch of 10 or fewer samples must be accompanied by a laboratory reagent 
blank (Section 9.5 of this appendix), corresponding NAF reference blanks 
(Section 9.6 of this appendix), a set of spiked duplicate samples blank 
(Section 9.4 of this appendix), and duplicate analysis of each field 
sample. If greater than 10 samples are to be extracted at one time, the 
samples must be separated into analytical batches of 10 or fewer 
samples.
    9.2 Initial demonstration of laboratory capability. To demonstrate 
the capability to perform the test, the analyst shall analyze two 
representative unused drilling fluids (e.g., internal olefin-based 
drilling fluid, vegetable ester-based drilling fluid), each prepared 
separately containing 0.1%, 1%, and 2% or a representative oil. Each 
drilling fluid/concentration combination shall be analyzed 10 times, and 
successful demonstration will yield the following average results for 
the data set:

0.1% oil--Detected in <20% of samples
1% oil--Detected in 75% of samples
2% oil--Detected in 90% of samples

    9.3 Sample duplicates.
    9.3.1 The laboratory shall prepare and analyze (Section 11.2 and 
11.4 of this appendix) each authentic sample in duplicate, from a given 
sampling site or, if for compliance monitoring, from a given discharge.
    9.3.2 The duplicate samples must be compared versus the prepared 
corresponding NAF blank.
    9.3.3 Prepare and analyze the duplicate samples according to 
procedures outlined in Section 11 of this appendix.
    9.3.4 The results of the duplicate analyses are acceptable if each 
of the results give the same response (fluorescence or no fluorescence). 
If the results are different, sample non-homogenicity issues may be a 
concern.

[[Page 333]]

Prepare the samples again, ensuring a well-mixed sample prior to 
extraction. Analyze the samples once again.
    9.3.5 If different results are obtained for the duplicate a second 
time, the analytical system is judged to be out of control and the 
problem shall be identified and corrected, and the samples re-analyzed.
    9.4 Spiked duplicates--Laboratory prepared spiked duplicates are 
analyzed to demonstrate acceptable accuracy and precision.
    9.4.1 Preparation and analysis of a set of spiked duplicate samples 
with each set of no more than 10 field samples is required to 
demonstrate method accuracy and precision and to monitor matrix 
interferences (interferences caused by the sample matrix). A field NAF 
sample expected to contain less than 0.5% crude oil (and documented to 
not fluoresce as part of the sample batch analysis) shall be spiked with 
1% (by volume) of suitable reference crude oil and analyzed as field 
samples, as described in Section 11 of this appendix. If no low-level 
drilling fluid is available, then the unused NAF can be used as the 
drilling fluid sample.
    9.5 Laboratory reagent blanks--Laboratory reagent blanks are 
analyzed to demonstrate freedom from contamination.
    9.5.1 A reagent blank is prepared by passing 4 mL of the isopropyl 
alcohol through a Teflon syringe filter and collecting the filtrate in a 
4-mL glass vial. A Sep Pak [supreg] C18 cartridge is then 
preconditioned with 3 mL of isopropyl alcohol. A 0.5-mL aliquot of the 
filtered isopropyl alcohol is added to the syringe barrel along with 3.0 
mL of isopropyl alcohol. The solvent is passed through the 
preconditioned Sep Pak [supreg] cartridge. An additional 2-mL of 
isopropyl alcohol is eluted through the cartridge. The cartridge is now 
considered the ``reagent blank'' cartridge and is ready for viewing 
(analysis). Check the reagent blank cartridge under the black light for 
fluorescence. If the isopropyl alcohol and filter are clean, no 
fluorescence will be observed.
    9.5.2 If fluorescence is detected in the reagent blank cartridge, 
analysis of the samples is halted until the source of contamination is 
eliminated and a prepared reagent blank shows no fluorescence under a 
black light. All samples shall be associated with an uncontaminated 
method blank before the results may be reported for regulatory 
compliance purposes.
    9.6 NAF reference blanks--NAF reference blanks are prepared from the 
NAFs sent from the supplier (NAF that has not been circulated downhole) 
and used as the reference when viewing the fluorescence of the test 
samples.
    9.6.1 A NAF reference blank is prepared identically to the authentic 
samples. Place a 0.1 mL aliquot of the ``clean'' NAF into a 25-mL glass 
vial. Add 10 mL of isopropyl alcohol to the vial. Cap the vial. Vortex 
the vial for approximately 10 sec. Allow the solids to settle for 
approximately 15 minutes. Using a 5-mL syringe, draw up 4 mL of the 
extract and filter it through a PTFE syringe filter, collecting the 
filtrate in a 4-mL glass vial. Precondition a Sep Pak [supreg] 
C18 cartridge with 3 mL of isopropyl alcohol. Add a 0.5-mL 
aliquot of the filtered extract to the syringe barrel along with 3.0 mL 
of isopropyl alcohol. Pass the extract and solvent through the 
preconditioned Sep Pak [supreg] cartridge. Pass an additional 2-mL of 
isopropyl alcohol through the cartridge. The cartridge is now considered 
the NAF blank cartridge and is ready for viewing (analysis). This 
cartridge is used as the reference cartridge for determining the absence 
or presence of fluorescence in all authentic drilling fluid samples that 
originate from the same NAF. That is, the specific NAF reference blank 
cartridge is put under the black light along with a prepared cartridge 
of an authentic sample originating from the same NAF material. The 
fluorescence or absence of fluorescence in the authentic sample 
cartridge is determined relative to the NAF reference cartridge.
    9.6.2 Positive control solution, equivalent to 1% crude oil 
contaminated mud extract, is prepared by dissolving 87 mg of standard 
crude oil into 10.00 mL of methylene chloride. Then mix 40 [micro]L of 
this solution into 10.00 mL of IPA. Transfer 0.5 mL of this solution 
into a preconditioned C18 cartridge, followed by 2 ml of IPA.

                  10.0 Calibration and Standardization

4-mL vial.
    11.2.7 Dispose of the PFTE syringe filter.
    11.2.8 Using a black permanent marker, label a Sep Pak [supreg] 
C18 cartridge with the sample identification.
    11.2.9 Place the labeled Sep Pak [supreg] C18 cartridge 
onto the head of a SPE vacuum manifold.
    11.2.10 Using a 5-mL disposable plastic syringe, draw up exactly 3-
mL (air free) of isopropyl alcohol.
    11.2.11 Attach the syringe tip to the top of the C18 
cartridge.
    11.2.12 Condition the C18 cartridge with the 3-mL of 
isopropyl alcohol by depressing the plunger slowly.
    Note: Depress the plunger just to the point when no liquid remains 
in the syringe barrel. Do not force air through the cartridge. Collect 
the eluate in a waste vial.
    11.2.13 Remove the syringe temporarily from the top of the 
cartridge, then remove the plunger, and finally reattach the syringe 
barrel to the top of the C18 cartridge.
    11.2.14 Using automatic pipetters and disposable pipette tips, 
transfer 0.5 mL of the filtered extract into the syringe barrel, 
followed by a 3.0-mL transfer of isopropyl alcohol to the syringe 
barrel.
    11.2.15 Insert the plunger and slowly depress it to pass only the 
extract and solvent through the preconditioned C18 cartridge.
    Note: Depress the plunger just to the point when no liquid remains 
in the syringe barrel. Do not force air through the cartridge. Collect 
the eluate in a waste vial.
    11.2.16 Remove the syringe temporarily from the top of the 
cartridge, then remove the plunger, and finally reattach the syringe 
barrel to the top of the C18 cartridge.
    11.2.17 Using an automatic pipetter and disposable pipette tip, 
transfer 2.0 mL of isopropyl alcohol to the syringe barrel.
    11.2.18 Insert the plunger and slowly depress it to pass the solvent 
through the C18 cartridge.
    Note: Depress the plunger just to the point when no liquid remains 
in the syringe barrel. Do not force air through the cartridge. Collect 
the eluate in a waste vial.
    11.2.19 Remove the syringe and labeled C18 cartridge from

NAF encountered in the field samples according to the procedures 
outlined in Section 9.6 of this appendix.
    11.2.22 Prepare the positive control (1% crude oil equivalent) 
according to Section 9.6.2 of this appendix.
    11.3 Reagent blank fluorescence testing.
    11.3.1 Place the reagent blank cartridge in a black box, under a 
black light.
    11.3.2 Determine the presence or absence of fluorescence for the 
reagent blank cartridge. If fluorescence is detected in the blank, 
analysis of the samples is halted until the source of contamination is 
eliminated and a prepared reagent blank shows no fluorescence under a 
black light. All samples must be associated with an uncontaminated 
method blank before the results may be reported for regulatory 
compliance purposes.
    11.4 Sample fluorescence testing.
    11.4.1 Place the respective NAF reference blank (Section 9.6 of this 
appendix) onto the tray inside the black box.

same NAF as the NAF reference blank) onto the tray, adjacent and to the 
right of the NAF reference blank.
    11.4.3 Turn on the black light.
    11.4.4 Compare the fluorescence of the sample cartridge with that of 
the negative control cartridge (NAF blank, Section 9.6.1 of this 
appendix) and positive control cartridge (1% crude oil equivalent, 
Section 9.6.2 of this appendix).
    11.4.5 If the fluorescence of the sample cartridge is equal to or 
brighter than the positive control cartridge (1% crude oil equivalent, 
Section 9.6.2 of this appendix), the sample is considered contaminated. 
Otherwise, the sample is clean.

Sec. Appendix 7 to Subpart A of Part 435--Determination of the Amount of 
  Non-Aqueous Drilling Fluid (NAF) Base Fluid From Drill Cuttings by a 
Retort Chamber (Derived From API Recommended Practice 13B-2) (EPA Method 
                                  1674)

                             1. Description

    a. This procedure is specifically intended to measure the amount of 
non-aqueous drilling fluid (NAF) base fluid from cuttings generated 
during a drilling operation. This procedure is a retort test which 
measures all oily material (NAF base fluid) and water released from a 
cuttings sample when heated in a calibrated and properly operating 
``Retort'' instrument.
    b. In this retort test a known mass of cuttings is heated in the 
retort chamber to vaporize the liquids associated with the sample. The 
NAF base fluid and water vapors are then condensed, collected, and 
measured in a precision graduated receiver.

    Note: Obtaining a representative sample requires special attention 
to the details of sample handling (e.g., location, method, frequency). 
See Addendum A and B for minimum requirements for collecting 
representative samples. Additional sampling procedures in a given area 
may be specified by the NPDES permit controlling authority.

                              2. Equipment

    a. Retort instrument--The recommended retort instrument has a 50-
cm\3\ volume with an external heating jacket.
    Retort Specifications:
    1. Retort assembly--retort body, cup and lid.
    (a) Material: 303 stainless steel or equivalent.
    (b) Volume: Retort cup with lid.
    Cup Volume: 50-cm\3\.
    Precision: 0.25-cm\3\.
    2. Condenser--capable of cooling the oil and water vapors below 
their liquification temperature.
    3. Heating jacket--nominal 350 watts.
    4. Temperature control--capable of limiting temperature of retort to 
at least 930 [deg]F (500 [deg]C) and enough to boil off all NAFs.
    b. Liquid receiver (10-cm\3\, 20-cm\3\)--the 10-cm\3\ and 20-cm\3\ 
receivers are specially designed cylindrical glassware with rounded 
bottom to facilitate cleaning and funnel-shaped top to catch falling 
drops. For compliance monitoring under the NPDES program, the analyst 
shall use the 10-cm\3\ liquid receiver with 0.1 ml graduations to 
achieve greater accuracy.
    1. Receiver specifications:
    Total volume: 10-cm\3\, 20-cm\3\.
    Precision (0 to 100%): 0.05 cm\3\, 0.05 cm\3\.
    Outside diameter: 10-mm, 13-mm.
    Wall thickness: 1.5 0.1mm, 1.2 0.1mm.
    Frequency of graduation marks (0 to 100%): 0.10-cm\3\, 0.10-cm\3\.
    Calibration: To contain ``TC'' @ 20 [deg]C.
    Scale: cm\3\, cm\3\
    2. Material--Pyrex [supreg] or equivalent glass.
    c. Toploading balance--capable of weighing 2000 g and precision of 
at least 0.1 g. Unless motion is a problem, the analyst shall use an 
electronic balance. Where motion is a problem, the analyst may use a 
triple beam balance.
    d. Fine steel wool (No. 000)--for packing retort body.
    e. Thread sealant lubricant: high temperature lubricant, e.g. Never-
Seez [supreg] or equivalent.
    f. Pipe cleaners--to clean condenser and retort stem.
    g. Brush--to clean receivers.
    h. Retort spatula--to clean retort cup.
    i. Corkscrew--to remove spent steel wool.

                              3. Procedure

    a. Clean and dry the retort assembly and condenser.

[[Page 336]]

    b. Pack the retort body with steel wool.
    c. Apply lubricant/sealant to threads of retort cup and retort stem.
    d. Weigh and record the total mass of the retort cup, lid, and 
retort body with steel wool. This is mass (A), grams.
    e. Collect a representative cuttings sample (see note in section 1 
of this appendix).
    f. Partially fill the retort cup with cuttings and place the lid on 
the cup.
    g. Screw the retort cup (with lid) onto the retort body, weigh and 
record the total mass. This is mass (B), grams.
    h. Attach the condenser. Place the retort assembly into the heating 
jacket.
    i. Weigh and record the mass of the clean and dry liquid receiver. 
This is mass (C), grams. Place the receiver below condenser outlet.
    j. Turn on the retort. Allow it to run a minimum of 1 hour.
    Note: If solids boil over into receiver, the test shall be rerun. 
Pack the retort body with a greater amount of steel wool and repeat the 
test.
    k. Remove the liquid receiver. Allow it to cool. Record the volume 
of water recovered. This is (V), cm\3\.
    Note: If an emulsion interface is present between the oil and water 
phases, heating the interface may break the emulsion. As a suggestion, 
remove the retort assembly from the heating jacket by grasping the 
condenser. Carefully heat the receiver along the emulsion band by gently 
touching the receiver for short intervals with the hot retort assembly. 
Avoid boiling the liquids. After the emulsion interface is broken, allow 
the liquid receiver to cool. Read the water volume at the lowest point 
of the meniscus.
    l. Weigh and record the mass of the receiver and its liquid contents 
(oil plus water). This is mass (D), grams.
    m. Turn off the retort. Remove the retort assembly and condenser 
from the heating jacket and allow them to cool. Remove the condenser.
    n. Weigh and record the mass of the cooled retort assembly without 
the condenser. This is mass (E), grams.
    o. Clean the retort assembly and condenser.

                             4. Calculations

    a. Calculate the mass of oil (NAF base fluid) from the cuttings as 
follows:
    1. Mass of the wet cuttings sample (Mw) equals the mass 
of the retort assembly with the wet cuttings sample (B) minus the mass 
of the empty retort assembly (A).

Mw = B-A [1]

    2. Mass of the dry retorted cuttings (MD) equals the mass 
of the cooled retort assembly (E) minus the mass of the empty retort 
assembly (A).

MD = E-A [2]

    3. Mass of the NAF base fluid (MBF) equals the mass of 
the liquid receiver with its contents (D) minus the sum of the mass of 
the dry receiver (C) and the mass of the water (V).

MBF = D-(C + V) [3]

    Note: Assuming the density of water is 1 g/cm\3\, the volume of 
water is equivalent to the mass of the water.
    b. Mass balance requirement:
    The sum of MD, MBF, and V shall be within 5% 
of the mass of the wet sample.

(MD + MBF + V)/Mw = 0.95 to 1.05 [4]

    The procedure shall be repeated if this requirement is not met.
    c. Reporting oil from cuttings:
    1. Assume that all oil recovered is NAF base fluid.
    2. The mass percent NAF base fluid retained on the cuttings 
(%BFi) for the sampled discharge ``i'' is equal to 100 times 
the mass of the NAF base fluid (MBF) divided by the mass of 
the wet cuttings sample (Mw).

%BFi = (MBF/Mw) x 100 [5]

    Operators discharging small volume NAF-cuttings discharges which do 
not occur during a NAF-cuttings discharge sampling interval (i.e., 
displaced interfaces, accumulated solids in sand traps, pit clean-out 
solids, or centrifuge discharges while cutting mud weight) shall either: 
(a) Measure the mass percent NAF base fluid retained on the cuttings 
(%BFSVD) for each small volume NAF-cuttings discharges; or 
(b) use a default value of 25% NAF base fluid retained on the cuttings.
    3. The mass percent NAF base fluid retained on the cuttings is 
determined for all cuttings wastestreams and includes fines discharges 
and any accumulated solids discharged [see Section 4.c.6 of this 
appendix for procedures on measuring or estimating the mass percent NAF 
base fluid retained on the cuttings (%BF) for dual gradient drilling 
seafloor discharges performed to ensure proper operation of subsea 
pumps].
    4. A mass NAF-cuttings discharge fraction (X, unitless) is 
calculated for all NAF-cuttings, fines, or accumulated solids discharges 
every time a set of retorts is performed (see Section 4.c.6 of this 
appendix for procedures on measuring or estimating the mass NAF-cuttings 
discharge fraction (X) for dual gradient drilling seafloor discharges 
performed to ensure proper operation of subsea pumps). The mass NAF-
cuttings discharge fraction (X) combines the mass of NAF-cuttings, 
fines, or accumulated solids discharged from a particular discharge over 
a set period of time with the total mass of NAF-cuttings, fines, or 
accumulated solids discharged into the ocean during the same period of 
time (see Addendum A and B of this appendix). The mass NAF-cuttings 
discharge

[[Page 337]]

fraction (X) for each discharge is calculated by direct measurement as:

Xi = (Fi)/(G) [6]

where:

Xi = Mass NAF-cuttings discharge fraction for NAF-cuttings, 
          fines, or accumulated solids discharge ``i'', (unitless)
Fi = Mass of NAF-cuttings discharged from NAF-cuttings, 
          fines, or accumulated solids discharge ``i'' over a specified 
          period of time (see Addendum A and B of this appendix), (kg)
G = Mass of all NAF-cuttings discharges into the ocean during the same 
          period of time as used to calculate Fi, (kg)

    If an operator has more than one point of NAF-cuttings discharge, 
the mass faction (Xi) must be determined by: (a) Direct 
measurement (see Equation 6 of this appendix); (b) using the following 
default values of 0.85 and 0.15 for the cuttings dryer (e.g., horizontal 
centrifuge, vertical centrifuge, squeeze press, High-G linear shakers) 
and fines removal unit (e.g., decanting centrifuges, mud cleaners), 
respectively, when the operator is only discharging from the cuttings 
dryer and the fines removal unit; or (c) using direct measurement of 
``Fi'' (see Equation 6 of this appendix) for fines and 
accumulated solids, using Equation 6A of this appendix to calculate 
``GEST'' for use as ``G'' in Equation 6 of this Appendix, and 
calculating the mass (kg) of NAF-cuttings discharged from the cuttings 
dryer (Fi) as the difference between the mass of 
``GEST'' calculated in Equation 6A of this appendix (kg) and 
the sum of all fines and accumulated solids mass directly measured (kg) 
(see Equation 6 of this appendix).

GEST = Estimated mass of all NAF-cuttings discharges into the 
          ocean during the same period of time as used to calculate 
          Fi (see Equation 6 of this appendix), (kg) [6A]

where:

GEST = Hole Volume (bbl) x (396.9 kg/bbl) x (1 + Z/100)
Z = The base fluid retained on cuttings limitation or standard (%) which 
          apply to the NAF being discharge (see Sec. Sec.  435.13. and 
          435.15).
Hole Volume (bbl) = [Cross-Section Area of NAF interval (in\2\)] x 
          Average Rate of Penetration (feet/hr) x period of time (min) 
          used to calculate Fi (see Equation 6 of this 
          appendix) x (1 hr/60 min) x (1 bbl/5.61 ft\3\) x (1 ft/12 
          in)\2\
Cross-Section Area of NAF interval (in\2\) = (3.14 x [Bit Diameter 
          (in)]\2\)/4
Bit Diameter (in) = Diameter of drilling bit for the NAF interval 
          producing drilling cuttings during the same period of time as 
          used to calculate Fi (see Equation 6 of this 
          appendix)
Average Rate of Penetration (feet/hr) = Arithmetic average of rate of 
          penetration into the formation during the same period of time 
          as used to calculate Fi (see Equation 6 of this 
          appendix)

    Note: Operators with one NAF-cuttings discharge may set the mass 
NAF-cuttings discharge fraction (Xi) equal to 1.0.

    5. Each NAF-cuttings, fines, or accumulated solids discharge has an 
associated mass percent NAF base fluid retained on cuttings value (%BF) 
and mass NAF-cuttings discharge fraction (X) each time a set of retorts 
is performed. A single total mass percent NAF base fluid retained on 
cuttings value (%BFT) is calculated every time a set of 
retorts is performed. The single total mass percent NAF base fluid 
retained on cuttings value (%BFT) is calculated as:

%BFT,j = [Sigma](Xi) x (%BFi) [7]

where:

%BFT,j = Total mass percent NAF base fluid retained on 
          cuttings value for retort set ``j'' (unitless as percentage, 
          %)
Xi = Mass NAF-cuttings discharge fraction for NAF-cuttings, 
          fines, or accumulated solids discharge ``i'', (unitless)
%BFi = Mass percent NAF base fluid retained on the cuttings 
          for NAF-cuttings, fines, or accumulated solids discharge ``i'' 
          , (unitless as percentage, %)

    Note: [Sigma]Xi = 1.

    Operators with one NAF-cuttings discharge may set %BFT,j 
equal to %BFi.
    6. Operators performing dual gradient drilling operations may 
require seafloor discharges of large cuttings (\1/4\[foot]) 
to ensure the proper operation of subsea pumps (e.g., electrical 
submersible pumps). Operators performing dual gradient drilling 
operations which lead to seafloor discharges of large cuttings for the 
proper operation of subsea pumps shall either: (a) Measure the mass 
percent NAF base fluid retained on cuttings value (%BF) and mass NAF-
cuttings discharge fraction (X) for seafloor discharges each time a set 
of retorts is performed; (b) use the following set of default values, 
(%BF = 14%; X = 0.15); or (c) use a combination of (a) and (b) (e.g., 
use a default value for %BF and measure X).
    Additionally, operators performing dual gradient drilling operations 
which lead to seafloor discharges of large cuttings for the proper 
operation of subsea pumps shall also perform the following tasks:
    (a) Use side scan sonar or shallow seismic to determine the presence 
of high density chemosynthetic communities. Chemosynthetic communities 
are assemblages of tube worms, clams, mussels, and bacterial mats that 
occur at natural hydrocarbon seeps or vents, generally in water depths 
of 500 meters or deeper. Seafloor discharges of large cuttings for the 
proper operation of subsea pumps shall not be permitted

[[Page 338]]

within 1000 feet of a high density chemosynthetic community.
    (b) Seafloor discharges of large cuttings for the proper operation 
of subsea pumps shall be visually monitored and documented by a Remotely 
Operated Vehicle (ROV) within the tether limit (approximately 300 feet). 
The visual monitoring shall be conducted prior to each time the 
discharge point is relocated (cuttings discharge hose) and conducted 
along the same direction as the discharge hose position. Near-seabed 
currents shall be obtained at the time of the visual monitoring.
    (c) Seafloor discharges of large cuttings for the proper operation 
of subsea pumps shall be directed within a 150 foot radius of the 
wellbore.
    7. The weighted mass ratio averaged over all NAF well sections 
(%BFwell) is the compliance value that is compared with the 
``maximum weighted mass ratio averaged over all NAF well sections'' BAT 
discharge limitations (see the table in Sec.  435.13 and footnote 5 of 
the table in Sec.  435.43) or the ``maximum weighted mass ratio averaged 
over all NAF well sections'' NSPS discharge limitations (see the table 
in Sec.  435.15 and footnote 5 of the table in Sec.  435.45). The 
weighted mass ratio averaged over all NAF well sections 
(%BFwell) is calculated as the arithmetic average of all 
total mass percent NAF base fluid retained on cuttings values 
(%BFT) and is given by the following expression:

%BFwell = [j = 1 to j = n [Sigma] (%BFT,j)]/n [8]

where:

%BFwell = Weighted mass ratio averaged over all NAF well 
          sections (unitless as percentage, %)
%BFT,j = Total mass percent NAF base fluid retained on 
          cuttings value for retort set ``j'' (unitless as percentage, 
          %)
n = Total number of retort sets performed over all NAF well sections 
          (unitless)

    Small volume NAF-cuttings discharges which do not occur during a 
NAF-cuttings discharge sampling interval (i.e., displaced interfaces, 
accumulated solids in sand traps, pit clean-out solids, or centrifuge 
discharges while cutting mud weight) shall be mass averaged with the 
arithmetic average of all total mass percent NAF base fluid retained on 
cuttings values (see Equation 8 of this appendix). An additional 
sampling interval shall be added to the calculation of the weighted mass 
ratio averaged over all NAF well sections (%BFwell). The mass 
fraction of the small volume NAF-cuttings discharges (XSVD) 
will be determined by dividing the mass of the small volume NAF-cuttings 
discharges (FSVD) by the total mass of NAF-cuttings 
discharges for the well drilling operation (GWELL + 
FSVD).

XSVD = FSVD / (GWELL + FSVD) 
          [9]

where:

XSVD = mass fraction of the small volume NAF-cuttings 
          discharges (unitless)
FSVD = mass of the small volume NAF-cuttings discharges (kg)
GWELL = mass of total NAF-cuttings from the well (kg)

    The mass of small volume NAF-cuttings discharges (FSVD) 
shall be determined by multiplying the density of the small volume NAF-
cuttings discharges ([rho]svd) times the volume of the small 
volume NAF-cuttings discharges (VSVD).

FSVD = [rho]svd x VSVD [10]

where:

FSVD = mass of small volume NAF-cuttings discharges (kg)
[rho]svd = density of the small volume NAF-cuttings 
          discharges (kg/bbl)
VSVD = volume of the small volume NAF-cuttings discharges 
          (bbl)
    The density of the small volume NAF-cuttings discharges shall be 
measured. The volume of small volume discharges (VSVD) shall 
be either: (a) Be measured or (b) use default values of 10 bbl of SBF 
for each interface loss and 75 bbl of SBM for pit cleanout per well.
    The total mass of NAF-cuttings discharges for the well 
(GWELL) shall be either: (a) Measured; or (b) calculated by 
multiplying 1.0 plus the arithmetic average of all total mass percent 
NAF base fluid retained on cuttings values [see Equation 8 of this 
appendix] times the total hole volume (VWELL) for all NAF 
well sections times a default value for the density the formation of 2.5 
g/cm\3\ (396.9 kg/bbl).
[GRAPHIC] [TIFF OMITTED] TR08JN01.001

where:

GWELL = total mass of NAF-cuttings discharges for the well 
          (kg)
[j = 1 to j = n [Sigma](%BFT,j)]/n = see Equation 8 of this 
          appendix (unitless as a percentage)
VWELL = total hole volume (VWELL) for all NAF well 
          sections (bbl)

    The total hole volume of NAF well sections (VWELL) will 
be calculated as:

[[Page 339]]

[GRAPHIC] [TIFF OMITTED] TR22JA01.170

    For wells where small volume discharges associated with cuttings are 
made, %BFWELL becomes:
[GRAPHIC] [TIFF OMITTED] TR08JN01.002

    Note: See Addendum A and B to determine the sampling frequency to 
determine the total number of retort sets required for all NAF well 
sections.

    8. The total number of retort sets (n) is increased by 1 for each 
sampling interval (see Section 2.4, Addendum A of this appendix) when 
all NAF cuttings, fines, or accumulated solids for that sampling 
interval are retained for no discharge. A zero discharge interval shall 
be at least 500 feet up to a maximum of three per day. This action has 
the effect of setting the total mass percent NAF base fluid retained on 
cuttings value (%BFT) at zero for that NAF sampling interval 
when all NAF cuttings, fines, or accumulated solids are retained for no 
discharge.
    9. Operators that elect to use the Best Management Practices (BMPs) 
for NAF-cuttings shall use the procedures outlined in Addendum B.

Addendum A to Appendix 7 to Subpart A of Part 435--Sampling of Cuttings 
      Discharge Streams for use with API Recommended Practice 13B-2

                         1.0 Sampling Locations

    1.1 Each NAF-cuttings waste stream that discharges into the ocean 
shall be sampled and analyzed as detailed in appendix 7. NAF-cuttings 
discharges to the ocean may include discharges from primary shakers, 
secondary shakers, cuttings dryer, fines removal unit, accumulated 
solids, and any other cuttings separation device whose NAF-cuttings 
waste is discharged to the ocean. NAF-cuttings wastestreams not directly 
discharged to the ocean (e.g., NAF-cuttings generated from shake shakers 
and sent to a cuttings dryer for additional processing) do not require 
sampling and analysis.
    1.2 The collected samples shall be representative of each NAF-
cuttings discharge. Operators shall conduct sampling to avoid the 
serious consequences of error (i.e., bias or inaccuracy). Operators 
shall collect NAF-cuttings samples near the point of origin and before 
the solids and liquid fractions of the stream have a chance to separate 
from one another. For example, operators shall collect shale shaker NAF-
cuttings samples at the point where NAF-cuttings are coming off the 
shale shaker and not from a holding container downstream where 
separation of larger particles from the liquid can take place.
    1.3 Operators shall provide a simple schematic diagram of the solids 
control system and sample locations to the NPDES permit controlling 
authority.

                2.0 Type of Sample and Sampling Frequency

    2.1 Each NAF-cuttings, fines, or accumulated solids discharge has an 
associated mass percent NAF base fluid retained on cuttings value (%BF) 
and mass NAF-cuttings discharge fraction (X) for each sampling interval 
(see Section 2.4 of this addendum). Operators shall collect a single 
discrete NAF-cuttings sample for each NAF-cuttings waste stream 
discharged to the ocean during every sampling interval.
    2.2 Operators shall use measured depth in feet from the Kelly 
bushing when samples are collected.
    2.3 The NAF-cuttings samples collected for the mass fraction 
analysis (see Equation 6, appendix 7 of subpart A of this part) shall 
also be used for the retort analysis (see Equations 1-5, appendix 7 of 
subpart A of this part).
    2.4 Operators shall collect and analyze at least one set of NAF-
cuttings samples per day while discharging. Operators engaged in fast 
drilling (i.e., greater than 500 linear NAF feet advancement of drill 
bit per day) shall collect and analyze one set of NAF-cuttings samples 
per 500 linear NAF feet of footage drilled. Operators are not required 
to collect and analyze more than three sets of NAF-cuttings samples per 
day (i.e., three sampling intervals). Operators performing zero 
discharge of all NAF-cuttings (i.e., all NAF cuttings, fines, or 
accumulated solids retained for no discharge) shall use the following 
periods to count sampling intervals:

[[Page 340]]

(1) One sampling interval per day when drilling is less than 500 linear 
NAF feet advancement of drill bit per day; and (2) one sampling interval 
per 500 linear NAF feet of footage drilled with a maximum of three 
sampling intervals per day.
    2.5 The operator shall measure the individual masses (Fi, 
kg) and sum total mass (G, kg) (see Equation 6, appendix 7 of subpart A 
of this part) over a representative period of time (e.g., <10 minutes) 
during steady-state conditions for each sampling interval (see Section 
2.4 of this addendum). The operator shall ensure that all NAF-cuttings 
are capture for mass analysis during the same sampling time period 
(e.g., <10 minutes) at approximately the same time (i.e., all individual 
mass samples collected within one hour of each other).
    2.6 Operators using Best Management Practices (BMPs) to control NAF-
cuttings discharges shall follow the procedures in Addendum B to 
appendix 7 of subpart A of 40 CFR 435.

                      3.0 Sample Size and Handling

    3.1 The volume of each sample depends on the volumetric flow rate 
(cm\3\/s) of the NAF-cuttings stream and the sampling time period (e.g., 
<10 minutes). Consequently, different solids control equipment units 
producing different NAF-cuttings waste streams at different volumetric 
flow rates will produce different size samples for the same period of 
time. Operators shall use appropriately sized sample containers for each 
NAF-cuttings waste stream to ensure no NAF-cuttings are spilled during 
sample collection. Operators shall use the same time period (e.g., <10 
minutes) to collect NAF-cuttings samples from each NAF-cuttings waste 
stream. Each NAF-cuttings sample size shall be at least one gallon. 
Operators shall clearly mark each container to identify each NAF-
cuttings sample.
    3.2 Operators shall not decant, heat, wash, or towel the NAF-
cuttings to remove NAF base fluid before mass and retort analysis.
    3.3 Operators shall first calculate the mass of each NAF-cuttings 
sample and perform the mass ratio analysis (see Equation 6, appendix 7 
of subpart A of this part). Operators with only one NAF-cuttings 
discharge may skip this step (see Section 4.c.4, appendix 7 of subpart A 
of this part).
    3.4 Operators shall homogenize (e.g., stirring, shaking) each NAF-
cuttings sample prior to placing a sub-sample into the retort cup. The 
bottom of the NAF-cuttings sample container shall be examined to be sure 
that solids are not sticking to it.
    3.5 Operators shall then calculate the NAF base fluid retained on 
cuttings using the retort procedure (see Equations 1-5, appendix 7 of 
subpart A of this part). Operators shall start the retort analyses no 
more than two hours after collecting the first individual mass sample 
for the sampling interval .
    3.6 Operators shall not discharge any sample before successfully 
completing the mass and retort analyses [i.e., mass balance requirements 
(see Section 4.b, appendix 7 of subpart A of this part) are satisfied]. 
Operators shall immediately re-run the retort analyses if the mass 
balance requirements (see Equation 4, appendix 7 of subpart A of this 
part) are not within a tolerance of 5% (see Section 4.b, Equation 4, 
appendix 7 of subpart A of this part).

                            4.0 Calculations

    4.1 Operators shall calculate a set of mass percent NAF base fluid 
retained on cuttings values (%BF) and mass NAF-cuttings discharge 
fractions (X) for each NAF-cuttings waste stream (see Section 1.1 of 
this addendum) for each sampling interval (see Section 2.4 of this 
addendum) using the procedures outlined in appendix 7 of subpart A of 
this part.
    4.2 Operators shall tabulate the following data for each individual 
NAF-cuttings sample: (1) Date and time of NAF-cuttings sample 
collection; (2) time period of NAF-cuttings sample collection (see 
Section 3.1 of this addendum); (3) mass and volume of each NAF-cuttings 
sample; (4) measured depth (feet) at NAF-cuttings sample collection (see 
Section 2.2 of this addendum); (5) respective linear feet of hole 
drilled represented by the NAF-cuttings sample (feet); and (6) the drill 
bit diameter (inches) used to generate the NAF-cuttings sample cuttings.
    4.3 Operators shall calculate a single total mass percent NAF base 
fluid retained on cuttings value (%BFT) for each sampling 
interval (see Section 2.4 of this addendum) using the procedures 
outlined in appendix 7 of subpart A of this part.
    4.4 Operators shall tabulate the following data for each total mass 
percent NAF base fluid retained on cuttings value (%BFT) for 
each NAF-cuttings sampling interval: (1) Date and starting and stopping 
times of NAF-cuttings sample collection and retort analyses; (2) 
measured depth of well (feet) at start of NAF-cuttings sample collection 
(see Section 2.2 of this addendum); (3) respective linear feet of hole 
drilled represented by the NAF-cuttings sample (feet); (4) the drill bit 
diameter (inches) used to generate the NAF-cuttings sample cuttings; and 
(5) annotation when zero discharge of NAF-cuttings is performed.
    4.5 Operators shall calculate the weighted mass ratio averaged over 
all NAF well sections (%BFwell) using the procedures outlined 
in appendix 7 of subpart A of this part.
    4.6 Operators shall tabulate the following data for each weighted 
mass ratio averaged over all NAF well sections (%BFwell) for 
each NAF well: (1) Starting and stopping dates of NAF well sections; (2) 
measured depth (feet)

[[Page 341]]

of all NAF well sections; (3) total number of sampling intervals (see 
Section 2.4 and Section 2.6 of this addendum); (4) number of sampling 
intervals tabulated during any zero discharge operations; (5) total 
volume of zero discharged NAF-cuttings over entire NAF well sections; 
and (6) identification of whether BMPs were employed (see Addendum B of 
appendix 7 of subpart A of this part).

   Addendum B to Appendix 7 to Subpart A of Part 435--Best Management 
      Practices (BMPs) for use with API Recommended Practice 13B-2

                          1.0 Overview of BMPs

    1.1 Best Management Practices (BMPs) are inherently pollution 
prevention practices. BMPs may include the universe of pollution 
prevention encompassing production modifications, operational changes, 
material substitution, materials and water conservation, and other such 
measures. BMPs include methods to prevent toxic and hazardous pollutants 
from reaching receiving waters. Because BMPs are most effective when 
organized into a comprehensive facility BMP Plan, operators shall 
develop a BMP in accordance with the requirements in this addendum.
    1.2 The BMP requirements contained in this appendix were compiled 
from several Regional permits, an EPA guidance document (i.e., Guidance 
Document for Developing Best Management Practices (BMP)'' (EPA 833-B-93-
004, U.S. EPA, 1993)), and draft industry BMPs. These common elements 
represent the appropriate mix of broad directions needed to complete a 
BMP Plan along with specific tasks common to all drilling operations.
    1.3 Operators are not required to use BMPs if all NAF-cuttings 
discharges are monitored in accordance with appendix 7 of subpart A of 
this part.

                   2.0 BMP Plan Purpose and Objectives

    2.1 Operators shall design the BMP Plan to prevent or minimize the 
generation and the potential for the discharge of NAF from the facility 
to the waters of the United States through normal operations and 
ancillary activities. The operator shall establish specific objectives 
for the control of NAF by conducting the following evaluations.
    2.2 The operator shall identify and document each NAF well that uses 
BMPs before starting drilling operations and the anticipated total feet 
to be drilled with NAF for that particular well.
    2.3 Each facility component or system controlled through use of BMPs 
shall be examined for its NAF-waste minimization opportunities and its 
potential for causing a discharge of NAF to waters of the United States 
due to equipment failure, improper operation, natural phenomena (e.g., 
rain, snowfall).
    2.4 For each NAF wastestream controlled through BMPs where 
experience indicates a reasonable potential for equipment failure (e.g., 
a tank overflow or leakage), natural condition (e.g., precipitation), or 
other circumstances to result in NAF reaching surface waters, the BMP 
Plan shall include a prediction of the total quantity of NAF which could 
be discharged from the facility as a result of each condition or 
circumstance.

                        3.0 BMP Plan Requirements

    3.1 The BMP Plan may reflect requirements within the pollution 
prevention requirements required by the Minerals Management Service (see 
30 CFR 250.300) or other Federal or State requirements and incorporate 
any part of such plans into the BMP Plan by reference.
    3.2 The operator shall certify that its BMP Plan is complete, on-
site, and available upon request to EPA or the NPDES Permit controlling 
authority. This certification shall identify the NPDES permit number and 
be signed by an authorized representative of the operator. This 
certification shall be kept with the BMP Plan. For new or modified NPDES 
permits, the certification shall be made no later than the effective 
date of the new or modified permit. For existing NPDES permits, the 
certification shall be made within one year of permit issuance.
    3.3 The BMP Plan shall:
    3.3.1 Be documented in narrative form, and shall include any 
necessary plot plans, drawings or maps, and shall be developed in 
accordance with good engineering practices. At a minimum, the BMP Plan 
shall contain the planning, development and implementation, and 
evaluation/reevaluation components. Examples of these components are 
contained in ``Guidance Document for Developing Best Management 
Practices (BMP)'' (EPA 833-B-93-004, U.S. EPA, 1993).
    3.3.2 Include the following provisions concerning BMP Plan review.
    3.3.2.1 Be reviewed by permittee's drilling engineer and offshore 
installation manager (OIM) to ensure compliance with the BMP Plan 
purpose and objectives set forth in Section 2.0.
    3.3.2.2 Include a statement that the review has been completed and 
that the BMP Plan fulfills the BMP Plan purpose and objectives set forth 
in Section 2.0. This statement shall have dated signatures from the 
permittee's drilling engineer and offshore installation manager and any 
other individuals responsible for development and implementation of the 
BMP Plan.
    3.4 Address each component or system capable of generating or 
causing a release of

[[Page 342]]

significant amounts of NAF and identify specific preventative or 
remedial measures to be implemented.

                       4.0 BMP Plan Documentation

    4.1 The operator shall maintain a copy of the BMP Plan and related 
documentation (e.g., training certifications, summary of the monitoring 
results, records of NAF-equipment spills, repairs, and maintenance) at 
the facility and shall make the BMP Plan and related documentation 
available to EPA or the NPDES Permit controlling authority upon request.

                        5.0 BMP Plan Modification

    5.1 For those NAF wastestreams controlled through BMPs, the operator 
shall amend the BMP Plan whenever there is a change in the facility or 
in the operation of the facility which materially increases the 
generation of those NAF-wastes or their release or potential release to 
the receiving waters.
    5.2 At a minimum the BMP Plan shall be reviewed once every five 
years and amended within three months if warranted. Any such changes to 
the BMP Plan shall be consistent with the objectives and specific 
requirements listed in this addendum. All changes in the BMP Plan shall 
be reviewed by the permittee's drilling engineer and offshore 
installation manager.
    5.3 At any time, if the BMP Plan proves to be ineffective in 
achieving the general objective of preventing and minimizing the 
generation of NAF-wastes and their release and potential release to the 
receiving waters and/or the specific requirements in this addendum, the 
permit and/or the BMP Plan shall be subject to modification to 
incorporate revised BMP requirements.

   6.0 Specific Pollution Prevention Requirements for NAF Discharges 
                        Associated with Cuttings

    6.1 The following specific pollution prevention activities are 
required in a BMP Plan when operators elect to control NAF discharges 
associated with cuttings by a set of BMPs.
    6.2 Establishing programs for identifying, documenting, and 
repairing malfunctioning NAF equipment, tracking NAF equipment repairs, 
and training personnel to report and evaluate malfunctioning NAF 
equipment.
    6.3 Establishing operating and maintenance procedures for each 
component in the solids control system in a manner consistent with the 
manufacturer's design criteria.
    6.4 Using the most applicable spacers, flushes, pills, and 
displacement techniques in order to minimize contamination of drilling 
fluids when changing from water-based drilling fluids to NAF and vice 
versa.
    6.5 A daily retort analysis shall be performed (in accordance with 
appendix 7 to subpart A of part 435) during the first 0.33 X feet 
drilled with NAF where X is the anticipated total feet to be drilled 
with NAF for that particular well. The retort analyses shall be 
documented in the well retort log. The operators shall use the 
calculation procedures detailed in appendix 7 to subpart A of part 435 
(see Equations 1 through 8) to determine the arithmetic average 
(%BFwell) of the retort analyses taken during the first 0.33 
X feet drilled with NAF.
    6.5.1 When the arithmetic average (%BFwell) of the retort 
analyses taken during the first 0.33 X feet drilled with NAF is less 
than or equal to the base fluid retained on cuttings limitation or 
standard (see Sec. Sec.  435.13 and 435.15), retort monitoring of 
cuttings may cease for that particular well. The same BMPs and drilling 
fluid used during the first 0.33 X feet shall be used for all remaining 
NAF sections for that particular well.
    6.5.2 When the arithmetic average (%BFwell) of the retort 
analyses taken during the first 0.33 X feet drilled with NAF is greater 
the base fluid retained on cuttings limitation or standard (see 
Sec. Sec.  435.13 and 435.15), retort monitoring shall continue for the 
following (second) 0.33 X feet drilled with NAF where X is the 
anticipated total feet to be drilled with NAF for that particular well. 
The retort analyses for the first and second 0.33 X feet shall be 
documented in the well retort log.
    6.5.2.1 When the arithmetic average (%BFwell) of the 
retort analyses taken during the first 0.66 X feet (i.e., retort 
analyses taken from first and second 0.33 X feet) drilled with NAF is 
less than or equal to the base fluid retained on cuttings limitation or 
standard (see Sec. Sec.  435.13 and 435.15), retort monitoring of 
cuttings may cease for that particular well. The same BMPs and drilling 
fluid used during the first 0.66 X feet shall be used for all remaining 
NAF sections for that particular well.

retort analyses taken during the first 0.66 X feet (i.e., retort 
analyses taken from first and second 0.33 X feet) drilled with NAF is 
greater than the base fluid retained on cuttings limitation or standard 
(see Sec. Sec.  435.13 and 435.15), retort monitoring shall continue for 
all remaining NAF sections for that particular well. The retort analyses 
for all NAF sections shall be documented in the well retort log.
    6.5.3 When the arithmetic average (%BFwell) of the retort 
analyses taken over all NAF sections for the entire well is greater that 
the base fluid retained on cuttings limitation or standard (see

NPDES permit requirements. Additionally, the operator shall, as part of 
the BMP Plan, initiate a reevaluation and modification to the BMP Plan 
in conjunction with equipment vendors and/or industry specialists.
    6.5.4 The operator shall include retort monitoring data and dates of 
retort-monitored and non-retort-monitored NAF-cuttings discharges 
managed by BMPs in their NPDES permit reports.

prior to a single analysis.
    (w) Minimum as applied to BAT effluent limitations and NSPS for 
drilling fluids and drill cuttings means the minimum 96-hour 
LC50. value allowed as measured in any single sample of the 
discharged waste stream. Minimum as applied to BPT and BCT effluent 
limitations and NSPS for sanitary wastes means the minimum concentration 
value allowed as measured in any single sample of the discharged waste 
stream.

procedure, ``Suspended Particulate Phase (SPP) Toxicity Test,'' 
presented in EPA Method 1619, which is published as an appendix to 
Subpart A of this part and in ``Analytic Methods for the Oil and Gas 
Extraction Point Source Category,'' EPA-821-R-11-004. See paragraph (mm) 
of this section.
    (ff) Static sheen test means the standard test procedure that has 
been developed for this industrial subcategory for the purpose of 
demonstrating compliance with the requirement of no discharge of free 
oil. The methodology for performing the static sheen test is presented 
in EPA Method 1617, which is published as an appendix to Subpart A of 
this part and in ``Analytic Methods for the Oil and Gas Extraction Point 
Source Category,'' EPA-821-R-11-004. See paragraph (mm) of this section.
    (gg) Stock barite means the barite that was used to formulate a 
drilling fluid.
    (hh) Synthetic material as applied to synthetic-based drilling fluid 
means material produced by the reaction of specific purified chemical 
feedstock, as opposed to the traditional base fluids such as diesel and 
mineral oil which are derived from crude oil solely through physical 
separation processes. Physical separation processes include 
fractionation and distillation and/or minor chemical reactions such as 
cracking and hydro processing. Since they are synthesized by the 
reaction of purified compounds, synthetic materials suitable for use in 
drilling fluids are typically free of polycyclic aromatic hydrocarbons 
(PAH's) but are sometimes found to contain levels of PAH up to 0.001 
weight percent PAH expressed as phenanthrene. Internal olefins and 
vegetable esters are two examples of synthetic materials suitable for 
use by the oil and gas extraction industry in formulating drilling 
fluids. Internal olefins are synthesized from the isomerization of 
purified straight-chain (linear) hydrocarbons such as

[[Page 349]]

C16-C18 linear alpha olefins. C16-
C18 linear alpha olefins are unsaturated hydrocarbons with 
the carbon to carbon double bond in the terminal position. Internal 
olefins are typically formed from heating linear alpha olefins with a 
catalyst. The feed material for synthetic linear alpha olefins is 
typically purified ethylene. Vegetable esters are synthesized from the 
acid-catalyzed esterification of vegetable fatty acids with various 
alcohols. EPA listed these two branches of synthetic fluid base 
materials to provide examples, and EPA does not mean to exclude other 
synthetic materials that are either in current use or may be used in the 
future. A synthetic-based drilling fluid may include a combination of 
synthetic materials.
    (ii) Well completion fluids means salt solutions, weighted brines, 
polymers, and various additives used to prevent damage to the well bore 
during operations which prepare the drilled well for hydrocarbon 
production.
    (jj) Well treatment fluids means any fluid used to restore or 
improve productivity by chemically or physically altering hydrocarbon-
bearing strata after a well has been drilled.
    (kk) Workover fluids means salt solutions, weighted brines, 
polymers, or other specialty additives used in a producing well to allow 
for maintenance, repair or abandonment procedures.
    (ll) 96-hour LC5. means the concentration (parts per million) or 
percent of the suspended particulate phase (SPP) from a sample that is 
lethal to 50 percent of the test organisms exposed to that concentration 
of the SPP after 96 hours of constant exposure.

Category is the EPA document, EPA-821-R-11-004, that compiles analytic 
methods for this category. Copies may be inspected at the National

Sec. Appendix 1 to Subpart D of Part 435--Procedure for Determining When 
  Coastal Cook Inlet Operators Qualify for an Exemption From the Zero 
Discharge Requirement for EMO-Cuttings and SBF-Cuttings in Coastal Cook 
                              Inlet, Alaska

                        1.0 Scope and Application

    This appendix is to be used to determine whether a Cook Inlet, 
Alaska, operator in Coastal waters (Coastal Cook Inlet operator) 
qualifies for the exemption to the zero discharge requirement 
established by 40 CFR 435.43 and 435.45 for drill cuttings associated 
with the following non-aqueous drilling fluids: enhanced mineral oil 
based drilling fluids (EMO-cuttings) and synthetic-based drilling fluids 
(SBF-cuttings). Coastal Cook Inlet operators are prohibited from 
discharging oil-based drilling fluids. This appendix is intended to 
define those situations under which technical limitations preclude 
Coastal Cook Inlet operators from complying with the zero discharge 
requirement for EMO-cuttings and SBF-cuttings. Coastal Cook Inlet 
operators that qualify for this exemption may be authorized to discharge 
EMO-cuttings and SBF-cuttings subject to the limitations applicable to 
operators in Offshore waters (see subpart A of this part).

                               2.0 Method

    2.1 Any Coastal Cook Inlet operator must achieve the zero discharge 
limit for EMO-cuttings and SBF-cuttings unless it successfully 
demonstrates that technical limitations prevent it from being able to 
dispose of its EMO-cuttings or SBF-cuttings through on-site annular 
disposal, injection into a Class II underground injection control (UIC) 
well, or onshore land application.
    2.2 To successfully demonstrate that technical limitations prevent 
it from being able to dispose of its EMO-cuttings or SBF-cuttings 
through on-site annular disposal, a Coastal Cook Inlet operator must 
show that it has been unable to establish formation injection in nearby 
wells that were initially considered for annular or dedicated disposal 
of EMO-cuttings or SBF-cuttings or prove to the satisfaction of the 
Alaska Oil and Gas Conservation Commission (AOGCC) that the EMO-cuttings 
or SBF-cuttings will be confined to the formation disposal interval. 
This demonstration must include:
    a. Documentation, including engineering analysis, that shows (1) an 
inability to establish formation injection (e.g., formation is too 
tight), (2) an inability to confine EMO-cuttings or SBF-cuttings in 
disposal formation (e.g., no confining zone or adequate barrier to 
confine wastes in formation), or (3) the occurrence of high risk 
emergency (e.g., mechanical failure of well, loss of ability to inject 
that risks loss of well which would cause significant economic harm or 
create a substantial risk to safety); and
    b. A risk analysis of alternative disposal options, including 
environmental assessment, human health and safety, and economic impact, 
that shows discharge as the lowest risk option.
    2.3 To successfully demonstrate that technical limitations prevent 
it from being able to dispose of its EMO-cuttings or SBF-cuttings 
through injection into a Class II UIC well, a Coastal Cook Inlet 
operator must show that it has been unable to establish injection into a 
Class II UIC well or prove to the satisfaction of the Alaska Oil and Gas 
Conservation Commission (AOGCC) that the EMO-cuttings or SBF-cuttings 
will be confined to the formation disposal interval. This demonstration 
must include:
    a. Documentation, including engineering analysis, that shows the 
inability to confine EMO-cuttings or SBF-cuttings in a Class II UIC well 
(e.g., no confining zone or adequate barrier to confine wastes in 
formation);
    b. Documentation demonstrating that no Class II UIC well is 
accessible (e.g., operator does not own, competitor will not allow 
injection); and
    c. A risk analysis of alternative disposal option, including 
environmental assessment, human health and safety, and economic impact, 
that shows discharge as the lowest risk option.
    2.4 To successfully demonstrate that technical limitations prevent 
it from being able to dispose of its EMO-cuttings or SBF-cuttings 
through land application, a Coastal Cook Inlet operator must show that 
it has been unable to handle drilling waste or dispose of EMO-cuttings 
or SBF-cuttings at an appropriate land disposal site. This demonstration 
must include:
    a. Documentation of site restrictions that preclude land application 
(e.g., no land disposal sites available);
    b. Documentation of the platform's lack of capacity for adequate 
storage of EMO-cuttings or SBF-cuttings (e.g., limited storage or room 
for cuttings transfer); or
    c. Documentation of inability to transfer EMO-cuttings or SBF-
cuttings from platform to land for disposal (e.g., extremely low tides, 
high wave action).

                              3.0 Procedure

    3.1 Except as described in Section 3.2 of this appendix, a Coastal 
Cook Inlet operator believing that it qualifies for the exemption to the 
zero discharge requirement for EMO-cuttings or SBF-cuttings must apply 
for and obtain an individual NPDES permit prior to discharging EMO-
cuttings or SBF-cuttings to waters of the United States.
    3.2 Discharges occurring as the result a high risk emergency (e.g., 
mechanical failure

[[Page 354]]

of well, loss of ability to inject that risks loss of well which would 
cause significant economic harm or safety) may be authorized by a 
general NPDES permit provided that:
    a. The Coastal Cook Inlet operator satisfactorily demonstrates to 
EPA Region 10 the fulfillment of the other exemption requirements 
described in Section 2.0 of this appendix, or
    b. The general permit allows for high risk emergency discharges and 
provides Reporting Requirements to EPA Region 10 immediately upon 
commencing discharge.

to an oil and gas facility shall be determined as follows:
    (1) An Oil and Gas facility, operator, or its agent or contractor 
may move its wastewaters from a facility located in one subcategory to 
another subcategory for treatment and return it to a location covered by 
the original subcategory for disposal. In such case, the effluent 
limitations guidelines, new source performance standards, or 
pretreatment standards for the original subcategory apply.
    (2) An Oil and Gas facility, operator, or its agent or contractor 
may move its wastewaters from a facility located in one subcategory to 
another subcategory for disposal or treatment and disposal, provided:
    (i) If an Oil and Gas facility, operator or its agent or contractor 
moves wastewaters from a wellhead located in one subcategory to another 
subcategory where oil and gas facilities are governed by less stringent 
effluent limitations guidelines, new source performance standards, or 
pretreatment standards, the more stringent effluent limitations 
guidelines, new source performance standards, or pretreatment standards 
applicable to the subcategory where the wellhead is located shall apply.
    (ii) If an Oil and Gas facility, operator or its agent moves 
effluent from a wellhead located in one subcategory to another 
subcategory where oil and gas facilities are governed by more stringent 
effluent limitations guidelines, new source performance standards, or 
pretreatment standards, the more stringent effluent limitations 
guidelines, new source performance standards, or pretreatment standards 
applicable at the point of discharge shall apply.

Sec.  437.1  General applicability.

    (a) Except as provided in paragraphs (b), (c), or (d) of this 
section, this part applies to that portion of wastewater discharges from 
a centralized waste treatment (CWT) facility that results from any of 
the following activities:
    (1) Treatment and recovery of hazardous or non-hazardous industrial 
metal-bearing wastes, oily wastes and organic-bearing wastes received 
from off-site; and
    (2) The treatment of CWT wastewater.
    (b) This part does not apply to the following discharges of 
wastewater from a CWT facility:
    (1) Wastewater from the treatment of wastes that are generated on-
site when the wastes generated on-site are otherwise subject to another 
part of subchapter N.
    (2) Wastewater from the treatment of wastes that are generated off-
site if the discharger: a) demonstrates that the off-site wastes are 
generated at a facility that is subject to the same provisions in 40 CFR 
subchapter N as non-CWT wastes generated at the CWT facility or b) 
demonstrates that the off-site wastes are of similar nature and the 
treatment of such wastes are compatible with the treatment of non-CWT 
wastes generated and treated at the CWT.
    (3) Wastewater from the treatment of wastes received from off-site 
via conduit (e.g., pipelines, channels, ditches, trenches, etc.) from 
the facility that generates the wastes unless the resulting wastewaters 
are commingled with other wastewaters subject to this provision. A 
facility that acts as a waste collection or consolidation center is not 
a facility that generates wastes.
    (4) Wastewater from product stewardship activities, the treatment of 
sanitary wastes and wastes of domestic origin including chemical toilet 
wastes, septage, and restaurant wastes or thermal drying of POTW 
biosolids. Product stewardship activities for purposes of this provision 
are limited to the following activities at a manufacturing facility: 
acceptance for treatment or recovery of its unused products, shipping 
and storage containers with product residues and off-spec products.
    (5) Wastewater from solids recovery operations so long as the wastes 
recovered are from non-industrial sources, and recovery of the wastes 
does not generate a wastewater or leach appreciable metal or organic 
chemicals or petroleum-based oil and grease into the water. Examples of 
solids recovery operations to which this subpart would not apply 
include, but are not limited to, the recycling of aluminum cans, glass 
and plastic bottles.
    (6) Wastewater from scrap metal processing or auto salvage 
operations.

[[Page 372]]

    (7) Wastewater from transfer stations or municipal recycling 
centers.
    (8) Wastewater from the treatment of, or recovery of material from, 
animal or vegetable fats/oils from grease traps or interceptors 
generated by facilities engaged in food service activities.
    (9) Wastewater from the treatment of, or recovery of material from, 
off-site wastes generated by facilities engaged only in food processing.
    (10) Wastewater from facilities that are subject to 40 CFR part 442. 
Wastewater resulting from the treatment of off-site wastewater generated 
in cleaning transportation equipment (or on-site wastewater generated in 
cleaning equipment) along with other off-site wastes (subject to this 
part) not generated in cleaning transportation equipment is, however, 
subject to this part.
    (11) Wastewater resulting from solvent recovery operations if the 
solvent recovery operations involve the separation of solvent mixtures 
by distillation.
    (12) Wastewater from facilities that are engaged exclusively in 
centralized silver recovery from used photographic or x-ray materials 
activities. The discharge resulting from centralized silver recovery 
from used photographic or x-ray materials that is treated at a CWT 
facility along with other off-site wastestreams (subject to this part) 
is subject to this part.
    (13) Wastewater from facilities that accept off-site wastes only for 
treatability studies, research and development, or chemical or physical 
analysis. The wastewater resulting from treatability studies, research 
and development, or chemical or physical analysis that is treated at a 
CWT facility along with other off-site wastestreams (subject to this 
part) is subject to this part.
    (c) This part also does not apply to the following activities:
    (1) ``Dry'' fuel blending operations, ``dry'' waste solidification/
stabilization operations, ``dry'' used oil filter or oily absorbents 
recycling operations, or ``dry'' high temperature metals recovery 
operations. However, this part does apply to wastewater discharges from 
a CWT resulting from any of these operations that do produce wastewater.
    (2) The discharge of marine generated wastes including wash water 
from equipment and tank cleaning, ballast water, bilge water, and other 
wastes generated (while operating on inland, coastal, or open waters or 
while berthed) as part of routine ship maintenance and operation as long 
as they are treated and discharged at the ship servicing facility where 
it is off-loaded. The discharges resulting from the treatment of marine 
generated wastes that are off-loaded and subsequently sent to a 
centralized waste treatment facility at a separate location are, 
however, subject to this part.
    (3) Discharge of wastewater from land treatment units or land 
application operations.
    (4) Discharge of wastewater from facilities that are engaged 
exclusively in landfilling activities and/or the treatment of landfill 
wastewaters (whether generated on or off-site). The discharge resulting 
from the treatment of landfill wastewater, whether generated on-site or 
off-site, treated at CWT facilities along with other off-site waste is, 
however, subject to this part.
    (5) Discharge of wastewater from facilities that are engaged 
exclusively in incineration activities. The discharge resulting from the 
treatment of off-site wastewater generated in the incineration of 
industrial waste that is treated at a CWT facility along with other off-
site wastestreams (subject to this part) is subject to this part.
    (d) Notwithstanding paragraph (a) of this section, the provisions of 
this part are not applicable to any metals treatment and recovery 
wastewater discharges which are subject to the secondary metals 
provisions of 40 CFR part 421, the Nonferrous Metals Manufacturing Point 
Source Category. These secondary metals subcategories are subpart C 
(Secondary Aluminum Smelting Subcategory), subpart F (Secondary Copper 
Subcategory), subpart L (Secondary Silver Subcategory), subpart M 
(Secondary Lead Subcategory), subpart P (Primary and Secondary Germanium 
and Gallium Subcategory), subpart Q (Secondary Indium Subcategory), 
subpart R (Secondary Mercury Subcategory), subpart

[[Page 373]]

T (Secondary Molybdenum and Vanadium Subcategory), subpart V (Secondary 
Nickel Subcategory), subpart X (Secondary Precious Metals Subcategory), 
subpart Z (Secondary Tantalum Subcategory), subpart AA (Secondary Tin 
Subcategory), subpart AB (Primary and Secondary Titanium Subcategory), 
subpart AC (Secondary Tungsten and Cobalt Subcategory), and subpart AD 
(secondary Uranium Subcategory).



Sec.  437.2  General definitions.

    As used in this part:
    (a) The general definitions and abbreviations in 40 CFR part 401 
apply to this part.
    (b) Alternative effluent limitations or pretreatment standards mean 
effluent limitations determined on a case-by-case basis under section 
402(a)(1) of the CWA or pretreatment standards developed as local limits 
by the control authority under 40 CFR Sec.  403.6(c) that apply to the 
discharge of wastewater subject to this provision. The permit writer (or 
control authority) will calculate these limitations or standards using a 
``building block'' approach or the ``combined wastestream formula.'' 
Under this approach, the permit writer (or control authority) will 
develop flow-weighted effluent limitations or standards for the treated 
combined wastestream by applying the limitations or standards in 40 CFR 
subchapter N that would otherwise apply to a particular wastestream 
received from off-site if the wastestream were treated and discharged 
from the facility at which it was generated.
    (c) Centralized waste treatment (CWT) facility means any facility 
that treats (for disposal, recycling or recovery of material) any 
hazardous or non-hazardous industrial wastes, hazardous or non-hazardous 
industrial wastewater, and/or used material received from off-site. 
``CWT facility'' includes both a facility that treats waste received 
exclusively from off-site and a facility that treats wastes generated 
on-site as well as waste received from off-site. For example, an organic 
chemical manufacturing plant may, in certain circumstances, be a CWT 
facility if it treats industrial wastes received from offsite as well as 
industrial waste generated at the organic chemical manufacturing plant. 
CWT facilities may also include re-refiners and may be owned by the 
federal government.
    (d) Centralized waste treatment wastewater means any wastewater 
generated as a result of CWT activities. CWT wastewater sources may 
include, but are not limited to: liquid waste receipts, solubilization 
water, used oil emulsion-breaking wastewater, tanker truck/drum/roll-off 
box washes, equipment washes, air pollution control scrubber blow-down, 
laboratory-derived wastewater, on-site landfill wastewaters, and 
contaminated storm water.
    (e) Contaminated storm water means storm water which comes in direct 
contact with CWT wastes, the waste handling and treatment areas, or 
other centralized waste treatment wastewater as defined in paragraph (d) 
of this section.
    (f) Discharger means a facility that discharges wastewater directly 
to waters of the United States or introduces wastewater to a publicly-
owned treatment works.
    (g) Dry means not producing a wastewater.
    (h) Equivalent treatment means a wastewater treatment system that 
achieves comparable pollutant removals to the applicable treatment 
technology selected as the basis for the limitations and pretreatment 
standards. Comparable removals may be demonstrated through literature, 
treatability tests, or self-monitoring data.
    (i) Fuel blending means the process of combining waste, wastewater, 
or used material for the purpose of regenerating a fuel for reuse. 
However, fuel blending may be loosely applied to any process where 
recovered hydrocarbons are combined as a fuel product where some 
pretreatment operations generate wastewater.
    (j) High temperature metals recovery means a metals recovery process 
in which solid forms of metal-containing materials are processed with a 
heat-based pyrometallurgical technology to produce a metal product.
    (k) Marine generated waste means any waste, wastewater, and/or used 
material generated as part of the normal

[[Page 374]]

maintenance and operation of a ship, boat, or barge operating on inland, 
coastal, or open waters, or while berthed.
    (l) Metal-bearing wastes means wastes and/or used materials from 
manufacturing or processing facilities or other commercial operations 
that contain significant quantities of metal pollutants, but not 
significant quantities of oil and grease (generally less than 100 mg/L). 
Examples of these wastes are spent electroplating baths and sludges, 
metal-finishing rinse water and sludges, chromate wastes, blow-down 
water and sludges from air pollution control, spent anodizing solutions, 
incineration air pollution control wastewaters, waste liquid mercury, 
cyanide containing wastes greater than 136 mg/L, and waste acids and 
bases with or without metals.
    (m) Multiple wastestream CWT facility means a CWT facility which 
accepts waste in more than one CWT subcategory (metals, oils, or 
organics) and combines any portion of these different subcategory wastes 
at any point prior to the compliance discharge sampling location.
    (n) Off-site means outside the boundaries of a facility.
    (o) Oily absorbent recycling means the process of recycling oil-
soaked or contaminated disposable rags, paper, or pads for the purpose 
of regenerating a fuel for reuse.
    (p) Oily wastes means wastes and/or used materials that contain oil 
and grease (generally at or in excess of 100 mg/L) from manufacturing or 
processing facilities or other commercial operations. Examples of these 
wastes are used oils, oil-water emulsions or mixtures, lubricants, 
coolants, contaminated groundwater clean-up from petroleum sources, used 
petroleum products, oil spill clean-up, bilge water, rinse/wash waters 
from petroleum sources, interceptor wastes, off-specification fuels, 
underground storage tank remediation waste, and tank clean out from 
petroleum or oily sources.
    (q) On-site means within the boundaries of a facility. A facility 
may encompass land areas that are bisected by public thoroughfares but 
are under the control of a common owner.
    (r) Organic wastes means wastes and/or used materials that contain 
organic pollutants, but not a significant quantity of oil and grease 
(generally less than 100 mg/L) from manufacturing or processing 
facilities or other commercial operations. Examples of these wastes are 
landfill leachate, contaminated groundwater clean-up from non-petroleum 
sources, solvent-bearing wastes, off-specification organic product, 
still bottoms, byproduct glycols, wastewater from paint washes, 
wastewater from adhesives and/or epoxies, wastewater from chemical 
product operations, and tank clean-out from organic, non-petroleum 
sources.

    (v) Pipeline means an open or closed conduit used for the conveyance 
of material. A pipeline includes a channel, pipe, tube, trench, or 
ditch, or fixed delivery system.
    (w) Product stewardship means a manufacturer's treatment or recovery 
of its own unused products, shipping and storage containers with product 
residues, off-specification products, and does not include spent or used 
materials from use of its products.
    (x) Re-refining means the processing of used oil using distillation, 
hydrotreating, and/or other treatment employing acid, caustic, solvent, 
clay and/or chemicals in order to produce high quality base stock for 
lubricants or other petroleum products.
    (y) Recovery means the recycling or processing of a waste, 
wastewater or used material such that the material, or a portion 
thereof, may be reused or converted to a raw material, intermediate, or 
product. Recovery does not include the re-use of treated or untreated 
wastewater in place of potable or pure water in industrial processes 
such as the use of secondary POTW effluents as non-contact cooling 
water, storm water in place of process water, or the re-use of spent 
chemicals in place of virgin treatment chemicals.
    (z) Solidification means the addition of sorbents to convert liquid 
or semi-liquid waste to a solid by means of adsorption, absorption or 
both. The process is usually accompanied by stabilization.

recycling of spent solvents through separation of solvent mixtures in 
distillation columns. Solvent recovery may require an additional, 
pretreatment step prior to distillation.
    (bb) Stabilization means a waste process that decreases the mobility 
of waste constituents by means of a chemical reaction. For the purpose 
of this rule, chemical precipitation is not a technique for 
stabilization.

change the physical, chemical or biological character or composition of 
any metal-bearing, oily, or organic wastes to neutralize such wastes; to 
render such wastes amenable to discharge; or to recover energy or 
recover metal, oil, or organic content from the wastes. Treatment does 
not include (a) the re-use of treated or untreated wastewater in place 
of potable or pure water in industrial processes such as the use of 
secondary POTW effluents as non-contact cooling water or storm water in 
place of process water or (b) the re-use of treated or untreated spent 
chemicals (such as pickle liquor) as treatment chemicals.
    (dd) Non-contaminated storm water means storm water which does not 
come in direct contact with CWT wastes, the waste handling and treatment 
areas, or other CWT wastewater that is defined in paragraph (d) of this 
section.
    (ee) Used oil filter recycling means crushing and draining of used 
oil filters of entrained oil and/or shredding and separation of used oil 
filters.
    (ff) Waste includes aqueous, non-aqueous, and solid waste, 
wastewater, and/or used material.



Sec.  437.3  General pretreatment standards.

    Any source subject to this part that introduces process wastewater 
pollutants into a publicly owned treatment works (POTW) must comply with 
40 CFR part 403.



Sec.  437.4  Monitoring requirements.

    (a) Permit compliance monitoring is required for each regulated 
parameter.
    (b) Any CWT facility that discharges wastewater resulting from the 
treatment of metal-bearing waste, oily waste, or organic-bearing waste 
must monitor as follows:
    (1) Facilities subject to more than one subpart of this part must 
monitor for compliance for each subpart after treatment and before 
mixing of the

[[Page 376]]

waste with wastes of any other subpart. Alternatively, a multiple 
wastestream subcategory facility may certify that it provides equivalent 
treatment as defined in Sec.  437.2(h) for the applicable waste and 
monitor for compliance with the applicable set of multiple wastestream 
subcategory limitations after mixing.
    (2) Facilities subject to one or more subpart of this part must 
monitor for compliance with the applicable subpart after treatment and 
before mixing of the waste with wastes of any other subpart, 
uncontaminated storm water, or wastewater subject to another effluent 
limitation or standard in subchapter N. If, however, the facility can 
demonstrate to the receiving POTW or permitting authority the capability 
of achieving the effluent limitation or standard for each subpart after 
treatment and before mixing with other wastestreams, the facility may 
monitor for compliance after mixing. In the case of a facility which 
elects to comply with the applicable set of multiple wastestream 
subcategory limitations or standards, it is only subject to one subpart.
    (3) When a CWT facility treats any waste receipt that contains 
cyanide at a concentration higher than 136 mg/L, the CWT facility must 
monitor for cyanide after cyanide treatment and before dilution with 
other wastestreams. If, however, the facility can demonstrate to the 
receiving POTW or permitting authority the capability of achieving the 
cyanide limitation or standard after cyanide treatment and before mixing 
with other wastestreams, the facility may monitor for compliance after 
mixing.



                 Subpart A_Metals Treatment and Recovery



Sec.  437.10  Applicability.

    (a) Except as provided in Sec.  437.1(b), (c), or (d) or in 
paragraph (b) of this section, this subpart applies to that portion of 
the discharge of wastewater from a CWT facility that results from the 
treatment of, or recovery of metals from, both metal-bearing wastes 
received from off-site and other CWT wastewater associated with the 
treatment of, or recovery of metal-bearing wastes.
    (b) In order to ensure appropriate treatment rather than dilution of 
dissimilar wastes, an NPDES permit writer or control authority may 
require a new source or an existing facility subject to this subpart to 
achieve alternative effluent limitations and standards as defined in 
Sec.  437.2(b) in the following circumstances:
    (1) The facility receives, on a continuing basis, flows of process 
wastewater from five or fewer facilities subject to 40 CFR subchapter N 
limitations and standards; and
    (2) The process wastewater flows received for treatment at the 
facility have relatively consistent pollutant profiles.



Sec.  437.11  Effluent limitations 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 or Sec.

        Sec. Appendix B to Part 438--Oily Operations Definitions

    Note: The definitions in this appendix shall not be used to 
differentiate between the six ``core'' metal finishing operations (i.e., 
Electroplating, Electroless Plating, Anodizing, Coating (chromating, 
phosphating, and coloring), Chemical Etching and Milling, and Printed 
Circuit Board Manufacture) and forty ``ancillary'' process operations 
listed at 40 CFR 433.10(a).
    Abrasive Blasting involves removing surface film from a part by 
using abrasive directed at high velocity against the part. Abrasive 
blasting includes bead, grit, shot, and sand blasting, and may be 
performed either dry or with water. The primary applications of wet 
abrasive blasting include: Removing burrs on precision parts; producing 
satin or matte finishes; removing fine tool marks; and removing light 
mill scale, surface oxide, or welding scale. Wet blasting can be used to 
finish fragile items such as electronic components. Also, some aluminum 
parts are wet blasted to achieve a fine-grained matte finish for 
decorative purposes. In abrasive blasting, the water and abrasive 
typically are reused until the particle size diminishes due to impacting 
and fracture.
    Adhesive Bonding involves joining parts using an adhesive material. 
Typically, an organic bonding compound is used as the adhesive. This 
operation usually is dry; however, aqueous solutions may be used as 
bonding agents or to contain residual organic bonding materials.

[[Page 397]]

    Alkaline Cleaning for Oil Removal is a general term for the 
application of an alkaline cleaning agent to a metal part to remove oil 
and grease during the manufacture, maintenance, or rebuilding of a metal 
product. This unit operation does not include washing of the finished 
products after routine use (as defined in ``Washing (Finished 
Products)'' in this appendix), or applying an alkaline cleaning agent to 
remove nonoily contaminants such as dirt and scale (as defined in 
``Alkaline Treatment Without Cyanide'' in this appendix and ``Alkaline 
Treatment With Cyanide'' in appendix C of this part). Wastewater 
generated includes spent cleaning solutions and rinse waters.
    (1) Alkaline cleaning is performed to remove foreign contaminants 
from parts. This operation usually is done prior to finishing (e.g., 
electroplating).
    (2) Emulsion cleaning is an alkaline cleaning operation that uses 
either complex chemical enzymes or common organic solvents (e.g., 
kerosene, mineral oil, glycols, and benzene) dispersed in water with the 
aid of an emulsifying agent. The pH of the solvent usually is between 7 
and 9, and, depending on the solvent used, cleaning is performed at 
temperatures from room temperature to 82 [deg]C (180 [deg]F). This 
operation often is used as a replacement for vapor degreasing.
    Alkaline Treatment Without Cyanide is a general term used to 
describe the application of an alkaline solution not containing cyanide 
to a metal surface to clean the metal surface or prepare the metal 
surface for further surface finishing.
    Aqueous Degreasing involves cleaning metal parts using aqueous-based 
cleaning chemicals primarily to remove residual oils and greases from 
the part. Residual oils can be from previous operations (e.g., machine 
coolants), oil from product use in a dirty environment, or oil coatings 
used to inhibit corrosion. Wastewater generated by this operation 
includes spent cleaning solutions and rinse waters.
    Assembly/Disassembly involves fitting together previously 
manufactured or rebuilt parts or components into a complete metal 
product or machine or taking a complete metal product or machine apart. 
Assembly/disassembly operations are typically dry; however, special 
circumstances can require water for cooling or buoyancy. Also, rinsing 
may be necessary under some conditions.
    Burnishing involves finish sizing or smooth finishing a part 
(previously machined or ground) by displacing, rather than removing, 
minute surface irregularities with smooth point or line-contact, fixed 
or rotating tools. Lubricants or soap solutions can be used to cool the 
tools used in burnishing operations. Wastewater generated during 
burnishing include process solutions and rinse water.
    Calibration is performed to provide reference points for the use of 
a product. This unit operation typically is dry, although water may be 
used in some cases (e.g., pumping water for calibration of a pump). 
Water used in this unit operation usually does not contain additives.
    Corrosion Preventive Coating involves applying removable oily or 
organic solutions to protect metal surfaces against corrosive 
environments. Corrosion preventive coatings include, but are not limited 
to: Petrolatum compounds, oils, hard dry-film compounds, solvent-cutback 
petroleum-based compounds, emulsions, water-displacing polar compounds, 
and fingerprint removers and neutralizers. Corrosion preventive coating 
does not include electroplating, or chemical conversion coating 
operations. Many corrosion preventive materials also are formulated to 
function as lubricants or as a base for paint. Typical applications 
include: Assembled machinery or equipment in standby storage; finished 
parts in stock or spare parts for replacement; tools such as drills, 
taps, dies, and gauges; and mill products such as sheet, strip, rod and 
bar. Wastewater generated during corrosion preventive coating includes 
spent process solutions and rinses. Process solutions are discharged 
when they become contaminated with impurities or are depleted of 
constituents. Corrosion preventive coatings typically do not require an 
associated rinse, but parts are sometimes rinsed to remove the coating 
before further processing.
    Electrical Discharge Machining involves removing metals by a rapid 
spark discharge between different polarity electrodes, one the part and 
the other the tool, separated by a small gap. The gap may be filled with 
air or a dielectric fluid. This operation is used primarily to cut tool 
alloys, hard nonferrous alloys, and other hard-to-machine materials. 
Most electrical discharge machining processes are operated dry; however, 
in some cases, the process uses water and generates wastewater 
containing dielectric fluid.
    Floor Cleaning (in Process Area) removes dirt, debris, and process 
solution spills from process area floors. Floors can be cleaned using 
wet or dry methods, such as vacuuming, mopping, dry sweeping, and hose 
rinsing. Non-process area floor cleaning in offices and other similar 
non-process areas is not included in this unit operation.
    Grinding involves removing stock from a part by using abrasive 
grains held by a rigid or semirigid binder. Grinding shapes or deburrs 
the part. The grinding tool usually is a disk (the basic shape of 
grinding wheels), but can also be a cylinder, ring, cup, stick, strip, 
or belt. The most commonly used abrasives are aluminum oxide, silicon 
carbide, and diamond. The process may use a grinding fluid to cool the 
part and remove debris or metal fines. Wastewater generated during 
grinding includes spent coolants and rinses. Metal-working fluids become 
spent for a

[[Page 398]]

number of reasons, including increased biological activity (i.e., the 
fluids become rancid) or decomposition of the coolant additives. Rinse 
waters typically are assimilated into the working fluid or treated on 
site.
    Heat Treating involves modifying the physical properties of a part 
by applying controlled heating and cooling cycles. This operation 
includes tempering, carburizing, cyaniding, nitriding, annealing, aging, 
normalizing, austenitizing, austempering, siliconizing, martempering, 
and malleablizing. Parts are heated in furnaces or molten salt baths, 
and then may be cooled by quenching in aqueous solutions (e.g., brine 
solutions), neat oils (pure oils with little or no impurities), or oil/
water emulsions. Heat treating typically is a dry operation, but is 
considered a wet operation if aqueous quenching solutions are used. 
Wastewater includes spent quench water and rinse water.
    Impact Deformation involves applying impact force to a part to 
permanently deform or shape it. Impact deformation may include 
mechanical processes such as hammer forging, shot peening, peening, 
coining, high-energy-rate forming, heading, or stamping. Natural and 
synthetic oils, light greases, and pigmented lubricants are used in 
impact deformation operations. Pigmented lubricants include whiting, 
lithapone, mica, zinc oxide, molybdenum disulfide, bentonite, flour, 
graphite, white lead, and soap-like materials. These operations 
typically are dry, but wastewater can be generated from lubricant 
discharge and from rinsing operations associated with the operation.
    Iron Phosphate Conversion Coating is the process of applying a 
protective coating on the surface of a metal using a bath consisting of 
a phosphoric acid solution containing no metals (e.g., manganese, 
nickel, or zinc) or a phosphate salt solution (i.e., sodium or potassium 
salts of phosphoric acid solutions) containing no metals (e.g., 
manganese, nickel, or zinc) other than sodium or potassium. Any metal 
concentrations in the bath are from the substrate.
    Machining involves removing stock from a part (as chips) by forcing 
a cutting tool against the part. This includes machining processes such 
as turning, milling, drilling, boring, tapping, planing, broaching, 
sawing, shaving, shearing, threading, reaming, shaping, slotting, 
hobbing, and chamfering. Machining processes use various types of metal-
working fluids, the choice of which depends on the type of machining 
being performed and the preference of the machine shop. The fluids can 
be categorized into four groups: Straight oil (neat oils), synthetic, 
semisynthetic, and water-soluble oil. Machining operations generate 
wastewater from working fluid or rinse water discharge. Metal-working 
fluids periodically are discarded because of reduced performance or 
development of a rancid odor. After machining, parts are sometimes 
rinsed to remove coolant and metal chips. The coolant reservoir is 
sometimes rinsed, and the rinse water is added to the working fluid.
    Painting-Spray or Brush (Including Water Curtains) involves applying 
an organic coating to a part. Coatings such as paint, varnish, lacquer, 
shellac, and plastics are applied by spraying, brushing, roll coating, 
lithographing, powder coating, and wiping. Water is used in painting 
operations as a solvent (water-borne formulations) for rinsing, for 
cleanup, and for water-wash (or curtain) type spray booths. Paint spray 
booths typically use most of the water in this unit operation. Spray 
booths capture overspray (i.e., paint that misses the product during 
application), and control the introduction of pollutants into the 
workplace and environment.
    Polishing involves removing stock from a part using loose or loosely 
held abrasive grains carried to the part by a flexible support. Usually, 
the objective is to achieve a desired surface finish or appearance 
rather then to remove a specified amount of stock. Buffing is included 
in this unit operation, and usually is performed using a revolving cloth 
or sisal buffing wheel, which is coated with a suitable compound. Liquid 
buffing compounds are used extensively for large-volume production on 
semiautomated or automated buffing equipment. Polishing operations 
typically are dry, although liquid compounds and associated rinses are 
used in some polishing processes.
    Pressure Deformation involves applying force (other than impact 
force) to permanently deform or shape a part. Pressure deformation may 
include rolling, drawing, bending, embossing, sizing, extruding, 
squeezing, spinning, necking, forming, crimping or flaring. These 
operations use natural and synthetic oils, light greases, and pigmented 
lubricants. Pigmented lubricants include whiting, lithapone, mica, zinc 
oxide, molybdenum disulfide, bentonite, flour, graphite, white lead, and 
soap-like materials. Pressure deformation typically is dry, but 
wastewater is sometimes generated from the discharge of lubricants or 
from rinsing associated with the process.
    Solvent Degreasing removes oils and grease from the surface of a 
part using organic solvents, including aliphatic petroleum (e.g., 
kerosene, naphtha), aromatics (e.g., benzene, toluene), oxygenated 
hydrocarbons (e.g., ketones, alcohol, ether), and halogenated 
hydrocarbons (e.g., 1,1,1-trichloroethane, trichloroethylene, methylene 
chloride). Solvent cleaning takes place in either the liquid or vapor 
phase. Solvent vapor degreasing normally is quicker than solvent liquid 
degreasing. However, ultrasonic vibration is sometimes used with liquid 
solvents to decrease the required immersion time of complex shapes. 
Solvent cleaning often is used as a precleaning operation prior to 
alkaline

[[Page 399]]

cleaning, as a final cleaning of precision parts, or as surface 
preparation for some painting operations. Solvent degreasing operations 
typically are not followed by rinsing, although rinsing is performed in 
some cases.
    Steam Cleaning removes residual dirt, oil, and grease from parts 
after processing though other unit operations. Typically, additives are 
not used in this operation; the hot steam removes the pollutants. 
Wastewater is generated when the cleaned parts are rinsed.
    Testing (e.g., hydrostatic, dye penetrant, ultrasonic, magnetic 
flux) involves applying thermal, electrical, mechanical, hydraulic, or 
other energy to determine the suitability or functionality of a part, 
assembly, or complete unit. Testing also may include applying surface 
penetrant dyes to detect surface imperfections. Other examples of tests 
frequently performed include electrical testing, performance testing, 
and ultrasonic testing; these tests typically are dry but may generate 
wastewater under certain circumstances. Testing usually is performed to 
replicate some aspect of the working environment. Wastewater generated 
during testing includes spent process solutions and rinses.
    Thermal Cutting involves cutting, slotting, or piercing a part using 
an oxy-acetylene oxygen lance, electric arc cutting tool, or laser. 
Thermal cutting typically is a dry process, except for the use of 
contact cooling waters and rinses.
    Tumbling/Barrel Finishing/Mass Finishing/Vibratory Finishing 
involves polishing or deburring a part using a rotating or vibrating 
container and abrasive media or other polishing materials to achieve a 
desired surface appearance. Parts to be finished are placed in a 
rotating barrel or vibrating unit with an abrasive media (e.g., ceramic 
chips, pebbles), water, and chemical additives (e.g., alkaline 
detergents). As the barrel rotates, the upper layer of the part slides 
toward the lower side of the barrel, causing the abrading or polishing. 
Similar results can be achieved in a vibrating unit, where the entire 
contents of the container are in constant motion, or in a centrifugal 
unit, which compacts the load of media and parts as the unit spins and 
generates up to 50 times the force of gravity. Spindle finishing is a 
similar process, where parts to be finished are mounted on fixtures and 
exposed to a rapidly moving abrasive slurry. Wastewater generated during 
barrel finishing includes spent process solutions and rinses. Following 
the finishing process, the contents of the barrel are unloaded. Process 
wastewater is either discharged continuously during the process, 
discharged after finishing, or collected and reused. The parts are 
sometimes given a final rinse to remove particles of abrasive media.
    Washing (Finished Products) involves cleaning finished metal 
products after use or storage using fresh water or water containing a 
mild cleaning solution. This unit operation applies only to the finished 
products that do not require maintenance or rebuilding.
    Welding involves joining two or more pieces of material by applying 
heat, pressure, or both, with or without filler material, to produce a 
metallurgical bond through fusion or recrystallization across the 
interface. This includes gas welding, resistance welding, arc welding, 
cold welding, electron beam welding, and laser beam welding. Welding 
typically is a dry process, except for the occasional use of contact 
cooling waters or rinses.
    Wet Air Pollution Control for Organic Constituents involves using 
water to remove organic constituents that are entrained in air streams 
exhausted from process tanks or production areas. Most frequently, wet 
air pollution control devices are used with cleaning and coating 
processes. A common type of wet air pollution control is the wet packed 
scrubber consisting of a spray chamber that is filled with packing 
material. Water is continuously sprayed onto the packing and the air 
stream is pulled through the packing by a fan. Pollutants in the air 
stream are absorbed by the water droplets and the air is released to the 
atmosphere. A single scrubber often serves numerous process tanks.



    Sec. Appendix C to Part 438--Metal-Bearing Operations Definitions

    Note: The definitions in this appendix shall not be used to 
differentiate between the six ``core'' metal finishing operations (i.e., 
Electroplating, Electroless Plating, Anodizing, Coating (chromating, 
phosphating, and coloring), Chemical Etching and Milling, and Printed 
Circuit Board Manufacture) and forty ``ancillary'' process operations 
listed at 40 CFR 433.10(a).
    Abrasive Jet Machining includes removing stock material from a part 
by a high-speed stream of abrasive particles carried by a liquid or gas 
from a nozzle. Abrasive jet machining is used for deburring, drilling, 
and cutting thin sections of metal or composite material. Unlike 
abrasive blasting, this process operates at pressures of thousands of 
pounds per square inch. The liquid streams typically are alkaline or 
emulsified oil solutions, although water also can be used.
    Acid Pickling Neutralization involves using a dilute alkaline 
solution to raise the pH of acid pickling rinse water that remains on 
the part after pickling. The wastewater from this operation is the acid 
pickling neutralization rinse water.
    Acid Treatment With Chromium is a general term used to describe any 
application of an acid solution containing chromium to a

[[Page 400]]

metal surface. Acid cleaning, chemical etching, and pickling are types 
of acid treatment. Chromic acid is used occasionally to clean cast iron, 
stainless steel, cadmium and aluminum, and bright dipping of copper and 
copper alloys. Also, chromic acid solutions can be used for the final 
step in acid cleaning phosphate conversion coating systems. Chemical 
conversion coatings formulated with chromic acid are defined at 
``Chromate Conversion Coating (or Chromating)'' in this appendix. 
Wastewater generated during acid treatment includes spent solutions and 
rinse waters. Spent solutions typically are batch discharged and treated 
or disposed of off site. Most acid treatment operations are followed by 
a water rinse to remove residual acid.
    Acid Treatment Without Chromium is a general term used to describe 
any application of an acid solution not containing chromium to a metal 
surface. Acid cleaning, chemical etching, and pickling are types of acid 
treatment. Wastewater generated during acid treatment includes spent 
solutions and rinse waters. Spent solutions typically are batch 
discharged and treated or disposed of off site. Most acid treatment 
operations are followed by a water rinse to remove residual acid.
    Alcohol Cleaning involves removing dirt and residue material from a 
part using alcohol.
    Alkaline Cleaning Neutralization involves using a dilute acid 
solution to lower the pH of alkaline cleaning rinse water that remains 
on the part after alkaline cleaning. Wastewater from this operation is 
the alkaline cleaning neutralization rinse water.
    Alkaline Treatment With Cyanide is the cleaning of a metal surface 
with an alkaline solution containing cyanide. Wastewater generated 
during alkaline treatment includes spent solutions and rinse waters. 
Alkaline treatment solutions become contaminated from the introduction 
of soils and dissolution of the base metal. They usually are treated and 
disposed of on a batch basis. Alkaline treatment typically is followed 
by a water rinse that is discharged to a treatment system.
    Anodizing With Chromium involves producing a protective oxide film 
on aluminum, magnesium, or other light metal, usually by passing an 
electric current through an electrolyte bath in which the metal is 
immersed. Anodizing may be followed by a sealant operation. Chromic acid 
anodic coatings have a relatively thick boundary layer and are more 
protective than are sulfuric acid coatings. For these reasons, chromic 
acid is sometimes used when the part cannot be rinsed completely. These 
oxide coatings provide corrosion protection, decorative surfaces, a base 
for painting and other coating processes, and special electrical and 
mechanical properties. Wastewaters generated during anodizing include 
spent anodizing solutions, sealants, and rinse waters. Because of the 
anodic nature of the process, anodizing solutions become contaminated 
with the base metal being processed. These solutions eventually reach an 
intolerable concentration of dissolved metal and require treatment or 
disposal. Rinse water following anodizing, coloring, and sealing 
typically is discharged to a treatment system.
    Anodizing Without Chromium involves applying a protective oxide film 
to aluminum, magnesium, or other light metal, usually by passing an 
electric current through an electrolyte bath in which the metal is 
immersed. Phosphoric acid, sulfuric acid, and boric acid are used in 
anodizing. Anodizing also may include sealant baths. These oxide 
coatings provide corrosion protection, decorative surfaces, a base for 
painting and other coating processes, and special electrical and 
mechanical properties. Wastewater generated during anodizing includes 
spent anodizing solutions, sealants, and rinse waters. Because of the 
anodic nature of the process, anodizing solutions become contaminated 
with the base metal being processed. These solutions eventually reach an 
intolerable concentration of dissolved metal and require treatment or 
disposal. Rinse water following anodizing, coloring, and sealing steps 
typically is discharged to a treatment systems.
    Carbon Black Deposition involves coating the inside of printed 
circuit board holes by dipping the circuit board into a tank that 
contains carbon black and potassium hydroxide. After excess solution 
dips from the circuit boards, they are heated to allow the carbon black 
to adhere to the board.
    Catalyst Acid Pre-Dip uses rinse water to remove residual solution 
from a part after the part is processed in an acid bath. The wastewater 
generated in this unit operation is the rinse water.
    Chemical Conversion Coating without Chromium is the process of 
applying a protective coating on the surface of a metal without using 
chromium. Such coatings are applied through phosphate conversion (except 
for ``Iron Phosphate Conversion Coating,'' see appendix B of this part), 
metal coloring, or passivation. Coatings are applied to a base metal or 
previously deposited metal to increase corrosion protection and 
lubricity, prepare the surface for additional coatings, or formulate a 
special surface appearance. This unit process includes sealant 
operations that use additives other than chromium.
    (1) In phosphate conversion, coatings are applied for one or more of 
the following reasons: to provide a base for paints and other organic 
coatings; to condition surfaces for cold forming operations by providing 
a base for drawing compounds and lubricants; to impart corrosion 
resistance to the metal surface; or to provide a suitable base for 
corrosion-resistant oils or waxes. Phosphate conversion coatings are 
formed by immersing a

[[Page 401]]

metal part in a dilute solution of phosphoric acid, phosphate salts, and 
other reagents.
    (2) Metal coloring by chemical conversion coating produces a large 
group of decorative finishes. Metal coloring includes the formation of 
oxide conversion coatings. In this operation, the metal surface is 
converted into an oxide or similar metallic compound, giving the part 
the desired color. The most common colored finishes are used on copper, 
steel, zinc, and cadmium.
    (3) Passivation forms a protective coating on metals, particularly 
stainless steel, by immersing the part in an acid solution. Stainless 
steel is passivated to dissolve embedded iron particles and to form a 
thin oxide film on the surface of the metal. Wastewater generated during 
chemical conversion coating includes spent solutions and rinses (i.e., 
both the chemical conversion coating solutions and post-treatment 
sealant solutions). These solutions commonly are discharged to a 
treatment system when contaminated with the base metal or other 
impurities. Rinsing normally follows each process step, except when a 
sealant dries on the part surface.
    Chemical Milling (or Chemical Machining) involves removing metal 
from a part by controlled chemical attack, or etching, to produce 
desired shapes and dimensions. In chemical machining, a masking agent 
typically is applied to cover a portion of the part's surface; the 
exposed (unmasked) surface is then treated with the chemical machining 
solution. Wastewater generated during chemical machining includes spent 
solutions and rinses. Process solutions typically are discharged after 
becoming contaminated with the base metal. Rinsing normally follows 
chemical machining.
    Chromate Conversion Coating (or Chromating) involves forming a 
conversion coating (protective coating) on a metal by immersing or 
spraying the metal with a hexavalent chromium compound solution to 
produce a hexavalent or trivalent chromium compound coating. This also 
is known as chromate treatment, and is most often applied to aluminum, 
zinc, cadmium or magnesium surfaces. Sealant operations using chromium 
also are included in this unit operation. Chromate solutions include two 
types: (1) those that deposit substantial chromate films on the 
substrate metal and are complete treatments themselves, and (2) those 
that seal or supplement oxide, phosphate, or other types of protective 
coatings. Wastewater generated during chromate conversion coating 
includes spent process solutions (i.e., both the chromate conversion 
coating solutions and post-treatment sealant solutions) and rinses. 
These solutions typically are discharged to a treatment system when 
contaminated with the base metal or other impurities. Also, chromium-
based solutions, which are typically formulated with hexavalent 
chromium, lose operating strength when the hexavalent chromium reduces 
to trivalent chromium during use. Rinsing normally follows each process 
step, except for sealants that dry on the surface of the part.
    Chromium Drag-out Destruction is a unit operation performed 
following chromium-bearing operations to reduce hexavalent chromium that 
is ``dragged out'' of the process bath. Parts are dipped in a solution 
of a chromium-reducing chemical (e.g., sodium metabisulfite) to prevent 
the hexavalent chromium from contaminating subsequent process baths. 
This operation typically is performed in a stagnant drag-out rinse tank 
that contains concentrated chromium-bearing wastewater.
    Cyanide Drag-out Destruction involves dipping part in a cyanide 
oxidation solution (e.g., sodium hypochloride) to prevent cyanide that 
is ``dragged out'' of a process bath from contaminating subsequent 
process baths. This operation typically is performed in a stagnant drag-
out rinse tank.
    Cyaniding Rinse is generated during cyaniding hardening of a part. 
The part is heated in a molten salt solution containing cyanide. 
Wastewater is generated when excess cyanide salt solution is removed 
from the part in rinse water.
    Electrochemical Machining is a process in which the part becomes the 
anode and a shaped cathode is the cutting tool. By pumping electrolyte 
between the electrodes and applying a current, metal is rapidly but 
selectively dissolved from the part. Wastewater generated during 
electrochemical machining includes spent electrolytes and rinses.
    Electroless Catalyst Solution involves adding a catalyst just prior 
to an electroless plating operation to accelerate the plating operation.
    Electroless Plating involves applying a metallic coating to a part 
using a chemical reduction process in the presence of a catalysis. An 
electric current is not used in this operations. The metal to be plated 
onto a part typically is held in solution at high concentrations using a 
chelating agent. This plates all areas of the part to a uniform 
thickness regardless of the configuration of the part. Also, an 
electroless-plated surface is dense and virtually nonporous. Copper and 
nickel electroless plating operations are the most common. Sealant 
operations (i.e., other than hot water dips) following electroless 
plating are considered separate unit operations if they include any 
additives. Wastewater generated during electroless plating includes 
spent process solutions and rinses. The wastewater contains chelated 
metals, which require separate preliminary treatment to break the metal 
chelates prior to conventional chemical precipitation. Rinsing follows 
most electroless plating processes to

[[Page 402]]

remove residual plating solution and prevent contamination of subsequent 
process baths.
    Electrolytic Cleaning involves removing soil, scale, or surface 
oxides from a part by electrolysis. The part is one of the electrodes 
and the electrolyte is usually alkaline. Electrolytic alkaline cleaning 
and electrolytic acid cleaning are the two types of electrolytic 
cleaning.
    (1) Electrolytic alkaline cleaning produces a cleaner surface than 
do nonelectrolytic methods of alkaline cleaning. This operation uses 
strong agitation, gas evolution in the solution, and oxidation-reduction 
reactions that occur during electrolysis. In addition, dirt particles 
become electrically charged and are repelled from the part surface.
    (2) Electrolytic acid cleaning sometimes is used as a final cleaning 
before electroplating. Sulfuric acid is most frequently used as the 
electrolyte. As with electrolytic alkaline cleaning, the mechanical 
scrubbing effect from the evolution of gas enhances the effectiveness of 
the process.
    Wastewater generated during electrolytic cleaning includes spent 
process solutions and rinses. Electrolytic cleaning solutions become 
contaminated during use due to the dissolution of the base metal and the 
introduction of pollutants. The solutions typically are batch discharged 
for treatment or disposal after they weaken. Rinsing following 
electrolytic cleaning removes residual cleaner to prevent contamination 
of subsequent process baths.
    Electroplating with Chromium involves producing a chromium metal 
coating on a surface by electrodeposition. Electroplating provides 
corrosion protection, wear or erosion resistance, lubricity, electrical 
conductivity, or decoration. In electroplating, metal ions in acid, 
alkaline, or neutral solutions are reduced on the cathodic surfaces of 
the parts being plated. Metal salts or oxides typically are added to 
replenish the solutions. Chromium trioxide often is added as a source of 
chromium. In addition to water and the metal being deposited, 
electroplating solutions often contain agents that form complexes with 
the metal being deposited, stabilizers to prevent hydrolysis, buffers 
for pH control, catalysts to assist in deposition, chemical aids to 
dissolve anodes, and miscellaneous ingredients that modify the process 
to attain specific properties. Sealant operations performed after this 
operation are considered separate unit operations if they include any 
additives (i.e., other than hot water dips). Wastewater generated during 
electroplating includes spent process solutions and rinses. 
Electroplating solutions occasionally become contaminated during use due 
to the base metal dissolving and the introduction of other pollutants, 
diminishing the effectiveness of the electroplating solutions 
diminishes. Spent concentrated solutions typically are treated to remove 
pollutants and reused, processed in a wastewater treatment system, or 
disposed of off site. Rinse waters, including some drag-out rinse tank 
solutions, typically are treated on site.
    Electroplating with Cyanide involves producing metal coatings on a 
surface by electrodeposition using cyanide. Electroplating provides 
corrosion protection, wear or erosion resistance, electrical 
conductivity, or decoration. In electroplating, metal ions in acid, 
alkaline, or neutral solutions are reduced on the cathodic surfaces of 
the parts being plated. The metal ions in solution typically are 
replenished by dissolving metal from anodes contained in inert wire or 
metal baskets. Sealant operations performed after this operation are 
considered separate unit operations if they include any additives (i.e., 
any sealant operations other than hot water dips). In addition to water 
and the metal being deposited, electroplating solutions often contain 
agents that form complexes with the metal being deposited, stabilizers 
to prevent hydrolysis, buffers to control pH, catalysts to assist in 
deposition, chemical aids to dissolve anodes, and miscellaneous 
ingredients that modify the process to attain specific properties. 
Cyanide, usually in the form of sodium or potassium cyanide, frequently 
is used as a complexing agent for zinc, cadmium, copper, and precious 
metal baths. Wastewater generated during electroplating includes spent 
process solutions and rinses. Electroplating solutions occasionally 
become contaminated during use due to dissolution of the base metal and 
the introduction of other pollutants, diminishing the performance of the 
electroplating solutions. Spent concentrated solutions typically are 
treated to remove pollutants and reused, processed in a wastewater 
treatment system, or disposed of off site. Rinse waters, including some 
drag-out rinse tank solutions, typically are treated on site.
    Electroplating without Chromium or Cyanide involves the production 
of metal coatings on a surface by electrodeposition, without using 
chromium or cyanide. Commonly electroplated metals include nickel, 
copper, tin/lead, gold, and zinc. Electroplating provides corrosion 
protection, wear or erosion resistance, lubricity, electrical 
conductivity, or decoration. In electroplating, metal ions in acid, 
alkaline, or neutral solutions are reduced on the cathodic surfaces of 
the parts being plated. The metal ions in solution typically are 
replenished by dissolving metal from anodes contained in inert wire or 
metal baskets. Sealant operations performed after this operation are 
considered separate unit operations if they include any additives (i.e., 
any sealant operations other than hot water dips). In addition to water 
and the metal being deposited, electroplating solutions often contain 
agents that form complexes

[[Page 403]]

with the metal being deposited, stabilizers to prevent hydrolysis, 
buffers to control pH, catalysts to assist in deposition, chemical aids 
to dissolve anodes, and miscellaneous ingredients that modify the 
process to attain specific properties. Wastewater generated during 
electroplating without chromium or cyanide includes spent process 
solutions and rinses. Electroplating solutions occasionally become 
contaminated during use due to dissolution of the base metal and the 
introduction of other pollutants, diminishing the effectiveness of the 
electroplating solutions. Spent concentrated solutions typically are 
treated for pollutant removal and reused, processed in a wastewater 
treatment system, or disposed of off site. Rinse waters, including some 
drag-out rinse tank solutions, typically are treated on site.
    Electropolishing involves producing a highly polished surface on a 
part using reversed electrodeposition in which the anode (part) releases 
some metal ions into the electrolyte to reduce surface roughness. When 
current is applied, a polarized film forms on the metal surface, through 
which metal ions diffuse. In this operation, areas of surface roughness 
on parts serve as high-current density areas and are dissolved at rates 
greater than the rates for smoother portions of the metal surface. 
Metals are electropolished to improve appearance, reflectivity, and 
corrosion resistance. Base metals processed by electropolishing include 
aluminum, copper, zinc, low-alloy steel, and stainless steel. Common 
electrolytes include sodium hydroxide and combinations of sulfuric acid, 
phosphoric acid, and chromic acid. Wastewater generated during 
electropolishing includes spent process solutions and rinses. 
Eventually, the concentration of dissolved metals increases to the point 
where the process becomes ineffective. Typically, a portion of the bath 
is decanted and either fresh chemicals are added or the entire solution 
is discharged to treatment and replaced with fresh chemicals. Rinsing 
can involve several steps and can include hot immersion or spray rinses.
    Galvanizing/Hot Dip Coating involves using various processes to coat 
an iron or steel surface with zinc. In hot dipping, a base metal is 
coated by dipping it into a tank that contains a molten metal.
    Hot Dip Coating involves applying a metal coating (usually zinc) to 
the surface of a part by dipping the part in a molten metal bath. 
Wastewater is generated in this operation when residual metal coating 
solution is removed from the part in rinse water.
    Kerfing uses a tool to remove small amounts of metal from a product 
surface. Water and synthetic coolants may be used to lubricate the area 
between the tool and the metal, to maintain the temperature of the 
cutting tool, and to remove metal fines from the surface of the part. 
This operation generates oily wastewater that contains metal fines and 
dust.
    Laminating involves applying a material to a substrate using heat 
and pressure.
    Mechanical and Vapor Plating involves applying a metallic coating to 
a part. For mechanical plating, the part is rotated in a drum containing 
a water-based solution, glass beads, and metal powder. In vapor plating, 
a metallic coating is applied by atomizing the metal and applying an 
electric charge to the part, which causes the atomized (vapor phase) 
metal to adhere to the part. Wastewater generated in this operation 
includes spent solutions from the process bath and rinse water. 
Typically, the wastewater contains high concentrations of the applied 
metal.
    Metallic Fiber Cloth Manufacturing involves weaving thin metallic 
fibers to create a mesh cloth.
    Metal Spraying (Including Water Curtain) involves applying a 
metallic coating to a part by projecting molten or semimolten metal 
particles onto a substrate. Coatings can be sprayed from rod or wire 
stock or from powdered material. The process involves feeding the 
material (e.g., wire) into a flame where it is melted. The molten stock 
then is stripped from the end of the wire and atomized by a high-
velocity stream of compressed air or other gas that propels the material 
onto a prepared substrate or part. Metal spraying coatings are used in a 
wide range of special applications, including: insulating layers in 
applications such as induction heating coils; electromagnetic 
interference shielding; thermal barriers for rocket engines; nuclear 
moderators; films for hot isostatic pressing; and dimensional 
restoration of worn parts. Metal spraying is sometimes performed in 
front of a ``water curtain'' (a circulated water stream used to trap 
overspray) or a dry filter exhaust hood that captures the overspray and 
fumes. With water curtain systems, water is recirculated from a sump or 
tank. Wastewater is generated when the sump or tank is discharged 
periodically. Metal spraying typically is not followed by rinsing.
    Painting-Immersion (Including Electrophoretic, ``E-coat'') involves 
applying an organic coating to a part using processes such autophoretic 
and electrophoretic painting.
    (1) Autophoretic Painting involves applying an organic paint film by 
electrophoresis when a part is immersed in a suitable aqueous bath.
    (2) Electrophoretic Painting is coating a part by making it either 
anodic or cathodic in a bath that is generally an aqueous emulsion of 
the organic coating material.
    (3) Other Immersion Painting includes all other types of immersion 
painting such as dip painting.

[[Page 404]]

    Water is used in immersion paint operations as a carrier for paint 
particles and to rinse the part. Aqueous painting solutions and rinses 
typically are treated through an ultrafiltration system. The concentrate 
is returned to the painting solution, and the permeate is reused as 
rinse water. Sites typically discharge a bleed stream to treatment. The 
painting solution and rinses are batch discharged periodically to 
treatment.
    Photo Imaging is the process of exposing a photoresist-laden printed 
wiring board to light to impact the circuitry design to the board. Water 
is not used in this operation.
    Photo Image Developing is an operation in which a water-based 
solution is used to develop the exposed circuitry in a photoresist-laden 
printed wiring board. Wastewater generated in this operation includes 
spent process solution and rinse water.
    Photoresist Application is an operation that uses heat and pressure 
to apply a photoresist coating to a printed wiring board. Water is not 
used in this operation.
    Photoresist Strip involves removing organic photoresist material 
from a printed wiring board using an acid solution.
    Phosphor Deposition is the application of a phosphorescent coating 
to a part. Wastewater generated in this unit operation includes water 
used to keep the parts clean and wet while the coating is applied, and 
rinse water used to remove excess phosphorescent coating from the part.
    Physical Vapor Deposition involves physically removing a material 
from a source through evaporation or sputtering, using the energy of the 
vapor particles in a vacuum or partial vacuum to transport the removed 
material, and condensing the removed material as a film onto the surface 
of a part or other substrate.
    Plasma Arc Machining involves removing material or shaping a part by 
a high-velocity jet of high-temperature, ionized gas. A gas (nitrogen, 
argon, or hydrogen) is passed through an electric arc, causing the gas 
to become ionized, and heated to temperatures exceeding 16,650 [deg]C 
(30,000 [deg]F). The relatively narrow plasma jet melts and displaces 
the material in its path. Because plasma arc machining does not depend 
on a chemical reaction between the gas and the part, and because plasma 
temperatures are extremely high, the process can be used on almost any 
metal, including those that are resistant to oxygen-fuel gas cutting. 
The method is used mainly for profile cutting of stainless steel and 
aluminum alloys. Although plasma arc machining typically is a dry 
process, water is used for water injection plasma arc torches. In these 
cases, a constricted swirling flow of water surrounds the cutting arc. 
This operations also may be performed immersed in a water bath. In both 
cases, water is used to stabilize the arc, to cool the part, and to 
contain smoke and fumes.
    Plastic Wire Extrusion involves applying a plastic material to a 
metal wire through an extrusion process.
    Salt Bath Descaling involves removing surface oxides or scale from a 
part by immersing the part in a molten salt bath or hot salt solution. 
Salt bath descaling solutions can contain molten salts, caustic soda, 
sodium hydride, and chemical additives. Molten salt baths are used in a 
salt bath-water quench-acid dip sequence to remove oxides from stainless 
steel and other corrosion-resistant alloys. In this process, the part 
typically is immersed in the molten salt, quenched with water, and then 
dipped in acid. Oxidizing, reducing, or electrolytic salt baths can be 
used depending on the oxide to be removed. Wastewater generated during 
salt bath descaling includes spent process solutions, quenches, and 
rinses.
    Shot Tower--Lead Shot Manufacturing involves dropping molten lead 
from a platform on the top of a tower through a sieve-like device and 
into a vat of cold water.
    Soldering involves joining metals by inserting a thin (capillary 
thickness) layer of nonferrous filler metal into the space between them. 
Bonding results from the intimate contact produced by the metallic bond 
formed between the substrate metal and the solder alloy. The term 
soldering is used where the melting temperature of the filler is below 
425 [deg]C (800 [deg]F). Some soldering operations use a solder flux, 
which is an aqueous or nonaqueous material used to dissolve, remove, or 
prevent the formation of surface oxides on the part. Except for the use 
of aqueous fluxes, soldering typically is a dry operation; however, a 
quench or rinse sometimes follows soldering to cool the part or remove 
excess flux or other foreign material from its surface. Recent 
developments in soldering technology have focused on fluxless solders 
and fluxes that can be cleaned off with water.
    Solder Flux Cleaning involves removing residual solder flux from a 
printed circuit board using either an alkaline or alcohol cleaning 
solution.
    Solder Fusing involves coating a tin-lead plated circuit board with 
a solder flux and then passing the board through a hot oil. The hot oil 
fuses the tin-lead to the board and creates a solder-like finish on the 
board.
    Solder Masking involves applying a resistive coating to certain 
areas of a circuit board to protect the areas during subsequent 
processing.
    Sputtering is a vacuum evaporation process in which portions of a 
coating material are physically removed from a substrate and deposited a 
thin film onto a different substrate.
    Stripping (Paint) involves removing a paint (or other organic) 
coating from a metal basis material. Stripping commonly is performed

[[Page 405]]

as part of the manufacturing process to recover parts that have been 
improperly coated or as part of maintenance and rebuilding to restore 
parts to a usable condition. Organic coatings (including paint) are 
stripped using thermal, mechanical, and chemical means. Thermal methods 
include burn-off ovens, fluidized beds of sand, and molten salt baths. 
Mechanical methods include scraping and abrasive blasting (as defined in 
``Abrasive Blasting'' in appendix B of this part). Chemical paint 
strippers include alkali solutions, acid solutions, and solvents (e.g., 
methylene chloride). Wastewater generated during organic coating 
stripping includes process solutions (limited mostly to chemical paint 
strippers and rinses).
    Stripping (Metallic Coating) involves removing a metallic coating 
from a metal basis material. Stripping is commonly part of the 
manufacturing process to recover parts that have been improperly coated 
or as part of maintenance and rebuilding to restore parts to a usable 
condition. Metallic coating stripping most often uses chemical baths, 
although mechanical means (e.g., grinding, abrasive blasting) also are 
used. Chemical stripping frequently is performed as an aqueous 
electrolytic process. Wastewater generated during metallic coating 
stripping includes process solutions and rinses. Stripping solutions 
become contaminated from dissolution of the base metal. Typically, the 
entire solution is discharged to treatment. Rinsing is used to remove 
the corrosive film remaining on the parts.
    Thermal Infusion uses heat to infuse metal powder or dust onto the 
surface of a part. Typically, thermal infusion is a dry operation. In 
some cases, however, water may be used to remove excess metal powder, 
metal dust, or molten metal.
    Ultrasonic Machining involves forcing an abrasive liquid between a 
vibrating tool and a part. Particles in the abrasive liquid strike the 
part, removing any microscopic flakes on the part.
    Vacuum Impregnation is used to reduce the porosity of the part. A 
filler material (usually organic) is applied to the surface of the part 
and polymerized under pressure and heat. Wastewater is generated in this 
unit operation when rinse water is used to remove residual organic 
coating from the part.
    Vacuum Plating involves applying a thin layer of metal oxide onto a 
part using molten metal in a vacuum chamber.
    Water Shedder involves applying a dilute water-based chemical 
compound to a part to accelerate drying. This operation typically is 
used to prevent a part from streaking when excess water remains on the 
part.
    Wet Air Pollution Control involves using water to remove chemicals, 
fumes, or dusts that are entrained in air streams exhausted from process 
tanks or production areas. Most frequently, wet air pollution control 
devices are used with electroplating, cleaning, and coating processes. A 
common type of wet air pollution control is the wet packed scrubber 
consisting of a spray chamber that is filled with packing material. 
Water is continuously sprayed onto the packing and the air stream is 
pulled through the packing by a fan. Pollutants in the air stream are 
absorbed by the water droplets and the air is released to the 
atmosphere. A single scrubber often serves numerous process tanks; 
however, the air streams typically are segregated by source into 
chromium, cyanide, and acid/alkaline sources. Wet air pollution control 
can be divided into several suboperations, including:
    (1) Wet Air Pollution Control for Acid Alkaline Baths;
    (2) Wet Air Pollution Control for Cyanide Baths;
    (3) Wet Air Pollution Control for Chromium-Bearing Baths; and
    (4) Wet Air Pollution Control for Fumes and Dusts.
    Wire Galvanizing Flux involves using flux to remove rust and oxide 
from the surface of steel wire prior to galvanizing. This provides long-
term corrosion protection for the steel wire.

[63 FR 50424, Sept. 21, 1998]



Sec.  439.1  General definitions.

    As used in this part:
    (a) The general definitions, abbreviations and methods of analysis 
in 40 CFR part 401 shall apply.
    (b) Bench-scale operation means the laboratory testing of materials, 
methods, or processes on a small scale, such as on a laboratory 
worktable.
    (c) Cyanide (T) means the parameter total cyanide.
    (d) In-plant monitoring point means a location within a plant, where 
an individual process effluent can be exclusively monitored before it is 
diluted or mixed with other process wastewaters en route to the end-of-
pipe.
    (e) Maximum daily means the highest allowable discharge of 
wastewater pollutants during a calendar day or any 24 hour period that 
reasonably represents a calendar day for purposes of sampling.
    (f) Maximum monthly average means the highest allowable average of 
daily discharges of wastewater pollutants over a calendar month, and is 
calculated as the sum of all daily values measured during a calendar 
month divided by the number of daily values measured during that month.
    (g) mg/L means milligrams per liter or parts per million (ppm)
    (h) Minimum level means the level at which an analytical system 
gives recognizable signals and an acceptable calibration point.
    (i) Nitrification capability means the capability of a POTW 
treatment system to oxidize ammonia or ammonium salts initially to 
nitrites (via Nitrosomonas bacteria) and subsequently to nitrates (via 
Nitrobacter bacteria). Criteria for determining the nitrification 
capability of a POTW treatment system are: bioassays confirming the 
presence of nitrifying bacteria; and analyses of the nitrogen balance 
demonstrating a reduction in the concentration of ammonia or ammonium 
salts and an increase in the concentrations of nitrites and nitrates.
    (j) Non-detect (ND) means a concentration value below the minimum 
level that can be reliably measured by the analytical method.
    (k) Pilot-scale operation means processing equipment being operated 
at an intermediate stage between laboratory-scale and full-scale 
operation for the purpose of developing a new product or manufacturing 
process.
    (l) POTW means publicly owned treatment works (40 CFR 403.3).

[[Page 408]]

    (m) Process wastewater, as defined at 40 CFR 122.2 and for the 
purposes of this part, does not include the following:
    (1) Trimethyl silanol, any active anti-microbial materials, process 
wastewater from imperfect fermentation batches, and process area spills. 
Discharges containing such materials are not subject to the limitations 
and standards of this part.
    (2) Non-contact cooling water, utility wastewaters, general site 
surface runoff, groundwater (e.g., contaminated groundwaters from on-
site or off-site groundwater remediation projects), and other non-
process water generated on site. Discharges of such waters and 
wastewaters are not subject to the limitations and standards of this 
part.
    (n) Non-conventional pollutants means parameters that are neither 
conventional pollutants (40 CFR 401.16), nor ``toxic'' pollutants (40 
CFR 401.15).
    (o) Surrogate pollutant means a regulated parameter that, for the 
purpose of compliance monitoring, is allowed to serve as a surrogate for 
a group of specific regulated parameters. Plants would be allowed to 
monitor for a surrogate pollutant(s), when the other parameters for 
which it stands are receiving the same degree of treatment as the 
surrogate pollutant(s) and all of the parameters discharged are in the 
same treatability class(es) as their respective surrogate pollutant(s). 
Treatability classes have been identified in appendix A of this part for 
both steam stripping and biological treatment technologies, which are 
the respective technology bases for PSES/PSNS and BAT/NSPS limitations 
controlling the discharge of regulated organic parameters.
    (p) Xylenes means a combination of the three isomers: o-xylene, m-
xylene, and p-xylene.

[63 FR 50425, Sept. 21, 1998; 64 FR 48104, Sept. 2, 1999, as amended at 
68 FR 12270, Mar. 13, 2003]



Sec.  439.2  General monitoring requirements.

    (a) Permit compliance monitoring is required for each regulated 
pollutant generated or used at a pharmaceutical manufacturing facility, 
except where the regulated pollutant is monitored as a surrogate 
parameter. Permit limits and compliance monitoring are not required for 
regulated pollutants that are neither used nor generated at the 
facility. Except for cyanide, for which an alternate monitoring 
requirement is established in subparts A and C of this part, a 
determination that regulated pollutants are neither used nor generated 
should be based on a review of all raw materials in use, and an 
assessment of the process chemistry, products and by-products resulting 
from each of the manufacturing processes. This determination along with 
a recommendation of any surrogate must be submitted with permit 
applications for approval by the permitting authority, reconfirmed by an 
annual chemical analysis of wastewater from each monitoring location, 
and measurement of a non-detect value for each regulated pollutant or 
its surrogate. Permits must specify that such determinations will be 
maintained in the facility's permit records with their discharge 
monitoring reports and will be available to regulatory authorities upon 
request.
    (b) Unless noted otherwise, self-monitoring will be conducted at the 
point where the final effluent is discharged.

[68 FR 12271, Mar. 13, 2003]



Sec.  439.3  General pretreatment standards.

    Any source subject to this part that introduces process wastewater 
pollutants into a publicly owned treatment works (POTW) must comply with 
40 CFR part 403.

[63 FR 50425, Sept. 21, 1998]



Sec.  439.4  General limitation or standard for pH.

    The pH must remain within the range 6.0 to 9.0 in any discharge 
subject to BPT, BCT or NSPS limitations or standards in this part.

[68 FR 12271, Mar. 13, 2003]



                     Subpart A_Fermentation Products



Sec.  439.10  Applicability.

    This subpart applies to discharges of process wastewater resulting 
from the

[[Page 409]]

manufacture of pharmaceutical products by fermentation.

[63 FR 50426, Sept. 21, 1998]



Sec.  439.11  Special definitions.

    For the purpose of this subpart:
    (a) Fermentation means process operations that utilize a chemical 
change induced by a living organism or enzyme, specifically, bacteria, 
or the microorganisms occurring in unicellular plants such as yeast, 
molds, or fungi to produce a specified product.
    (b) Product means pharmaceutical products derived from fermentation 
processes.

[68 FR 12271, Mar. 13, 2003]



Sec.  439.12  Effluent limitations 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 application of BPT:
    (a) The maximum monthly average limitation for BOD5, 
expressed as mass loading (lbs., kg) per day, must reflect not less than 
90 percent reduction in the long-term average daily BOD5 load 
of the raw (untreated) process wastewater, multiplied by a variability 
factor of 3.0.
    (1) The long-term average daily BOD5 load of the raw 
process wastewater (i.e., the base number to which the percent reduction 
is applied) is defined as the average daily BOD5 load during 
any calendar month, over 12 consecutive months within the most recent 36 
months, and must include one or more periods during which production was 
at a maximum.
    (2) To assure equity in the determination of NPDES permit 
limitations regulating discharges subject to this subpart, calculation 
of the long-term average daily BOD5 load in the influent to 
the wastewater treatment system must exclude any portion of the load 
associated with separable mycelia and solvents, except for residual 
amounts of mycelia and solvents remaining after the practices of 
recovery and/or separate disposal or reuse. These residual amounts may 
be included in the calculation of the average influent BOD5 
loading.
    (3) The practices of recovery, and/or separate disposal or reuse 
include: physical separation and removal of separable mycelia; recovery 
of solvents from waste streams; incineration of concentrated solvent 
wastestreams (including tar still bottoms); and concentration of broth 
for disposal other than to the treatment system. This part does not 
prohibit the inclusion of such wastes in raw waste loads in fact, nor 
does it mandate any specific practice, but rather describes the 
rationale for determining NPDES permit limitations. The effluent 
limitation for BOD5 may be achieved by any of several, or a 
combination, of these practices.
    (b) The maximum monthly average limitation for TSS, expressed as 
mass loading (lbs., kg) per day, must be calculated as 1.7 times the 
BOD5 limitation determined in paragraph (a) of this section.
    (c) Except as provided in paragraph (d) of this section, the 
limitations for COD are as follows:

                       Effluent Limitations (BPT)
------------------------------------------------------------------------
                                                                Maximum
                                                     Maximum    monthly
                Regulated parameter                 daily \1\   average
                                                                  \1\
------------------------------------------------------------------------
COD...............................................       1675       856
------------------------------------------------------------------------
\1\mg/L (ppm).

    (d) If the maximum monthly average COD concentration in paragraph 
(c) of this section is higher than a concentration value reflecting a 
reduction in the long-term average daily COD load in the raw (untreated) 
process wastewater of 74 percent multiplied by a variability factor of 
2.2, then the monthly average limitation for COD corresponding to the 
lower concentration value must be applied.
    (e) The effluent limitations for cyanide are as follows:

                       Effluent Limitations (BPT)
------------------------------------------------------------------------
                                                                Maximum
                                                     Maximum    monthly
                Regulated parameter                 daily \1\   average
                                                                  \1\

\1\mg/L (ppm).


[[Page 410]]

    (f) When monitoring for cyanide at the end-of-pipe is impractical 
because of dilution by other process wastewaters, compliance with the 
cyanide effluent limitations in paragraph (e) of this section must be 
demonstrated at in-plant monitoring points pursuant to 40 CFR 122.44(i) 
and 122.45(h). Under the same provisions, the permitting authority may 
impose monitoring requirements on internal wastestreams for any other 
parameter(s) regulated by this section.
    (g) Compliance with the limitation in paragraph (e) or (f) of this 
section may be achieved by certifying to the permit issuing authority 
that the facility's manufacturing processes neither use nor generate 
cyanide.

                      Subpart B_Extraction Products



Sec.  439.20  Applicability.

    This subpart applies to discharges of process wastewater resulting 
from the manufacture of pharmaceutical products by extraction.

[63 FR 50430, Sept. 21, 1998]



Sec.  439.21  Special definitions.

    For the purpose of this subpart:
    (a) Extraction means process operations that derive pharmaceutically 
active ingredients from natural sources such as plant roots and leaves, 
animal glands, and parasitic fungi by chemical and physical extraction.
    (b) Product means any substance manufactured by an extraction 
process, including blood fractions, vaccines, serums, animal bile 
derivatives, endocrine products and medicinal products such as alkaloids 
that are isolated from botanical drugs and herbs.

[68 FR 12272, Mar. 13, 2003]



Sec.  439.22  Effluent limitations 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 application of BPT:
    (a) The limitation for BOD5 is the same as specified in 
Sec.  439.12(a). No facility shall be required to attain a monthly 
average limitation for BOD5 that is less than the equivalent 
of 45 mg/L.
    (1) The long-term average daily BOD5 load of the raw 
process wastewater (i.e., the base number to which the percent reduction 
is applied) is defined as the average daily BOD5 load during 
any calendar month, over 12 consecutive months within the most recent 36 
months, and must include one or more periods during which production was 
at a maximum.
    (2) To assure equity in the determination of NPDES permit 
limitations regulating discharges subject to this subpart, calculation 
of the long-term average daily BOD5 load in the influent to 
the wastewater treatment system must exclude any portion of the load 
associated with separable mycelia and solvents, except for residual 
amounts of mycelia and solvents remaining after the practices of 
recovery and/or separate disposal or reuse. Residual amounts of these 
substances may be included in the calculation of the average influent 
BOD5 loading.
    (3) The practices of recovery, and/or separate disposal or reuse 
include: physical separation and removal of separable mycelia; recovery 
of solvents from wastestreams; incineration of concentrated solvent 
wastestreams (including tar still bottoms); and broth concentration for 
disposal other than to the treatment system. This part does not prohibit 
the inclusion of such wastes in raw waste loads in fact, nor does it 
mandate any specific practice, but rather describes the rationale for 
determining NPDES permit limitations. The effluent limitation for 
BOD5 may be achieved by any of several, or a combination, of 
these practices.
    (b) The limitation for TSS is the same as specified in Sec.  
439.12(b).
    (c) Except for the provisions in paragraph (d) of this section, the 
limitations for COD are as follows:

                       Effluent Limitations (BPT)
------------------------------------------------------------------------
                                                                Maximum
                                                     Maximum    monthly

    (d) If the maximum monthly average COD concentration in paragraph 
(c) of this section is higher than a concentration value reflecting a 
reduction in the long-term average daily COD load in the raw (untreated) 
process wastewater of 74 percent multiplied by a variability factor of 
2.2, then a monthly average limitation for COD corresponding

[[Page 413]]

to the lower concentration value must be applied.

conventional pollutant control technology (BCT).

    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 application of BCT: Limitations for 
BOD5, TSS and pH are the same as the corresponding 
limitations in Sec.  439.22.

[63 FR 50430, Sept. 21, 1998]



Sec.  439.24  Effluent limitations attainable by the application of best 
available technology economically achievable (BAT).

    Except as provided in 40 CFR 125.30 through 125.32, any existing 
point source subject to this subpart must achieve the following effluent 
limitations representing the application of BAT: Limitations for COD are 
the same as the corresponding limitations in Sec.  439.22(c) and (d).

Sec.  439.50  Applicability.

    This subpart applies to discharges of process wastewater resulting 
from pharmaceutical research.

[63 FR 50436, Sept. 21, 1998]



Sec.  439.51  Special definitions.

    For the purpose of this subpart, product means products or services 
resulting from research and product development activities.

[68 FR 12274, Mar. 13, 2003]



Sec.  439.52  Effluent limitations 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 application of BPT:
    (a) The limitation for BOD5 is the same as specified in 
Sec.  439.12(a). No facility shall be required to attain a monthly 
average limitation for BOD5 that is less than the equivalent 
of 45 mg/L.
    (b) The limitation for TSS is the same as specified in Sec.  
439.12(b).
    (c) The maximum monthly average limitation for COD, expressed as 
mass loading (lbs, kg) per day, must reflect not less than 74 percent 
reduction in the long-term average daily COD load of the raw (untreated) 
process wastewater, multiplied by a variability factor of 2.2. No 
facility shall be required to attain a limitation for COD that is less 
than the equivalent of 220 mg/L.
    (d) The long-term average daily BOD5 or COD mass loading 
of the raw process wastewater (i.e., the base number to which the 
percent reduction is applied) is defined as the average daily 
BOD5 or COD load during any calendar month, over 12 
consecutive months within the most recent 36 months.
    (1) To assure equity in the determination of NPDES permit 
limitations regulating discharges subject to this subpart, calculation 
of the long-term average daily BOD5 or COD load in the 
influent to the wastewater treatment system must exclude any portion of 
the load associated with solvents, except

[[Page 417]]

for residual amounts of solvents remaining after the practices of 
recovery and/or separate disposal or reuse. Residual amounts of these 
substances may be included in the calculation of the average influent 
BOD5 or COD loading.
    (2) The practices of recovery, and/or separate disposal or reuse 
include: recovery of solvents from wastestreams; and incineration of 
concentrated solvent wastestreams (including tar still bottoms). This 
regulation does not prohibit the inclusion of such wastes in raw waste 
loads in fact, nor does it mandate any specific practice, but rather 
describes the rationale for determining NPDES permit limitations. The 
effluent limitation for BOD5 or COD may be achieved by any of 
several, or a combination, of these practices.
    (e) The pH must be within the range 6.0 to 9.0.

    (b)(1) Except as provided in paragraph (b) of this section, there 
shall be no discharge of process wastewater to navigable waters from 
mills beneficiating mercury ores by gravity separation methods or by 
froth-flotation methods. 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.

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



              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 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

[[Page 439]]

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.

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 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

[[Page 442]]

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.

Sec.  442.1  General applicability.

    (a) As defined more specifically in each subpart, and except for 
discharges specified in paragraph (b) of this section, this part applies 
to discharges resulting from cleaning the interior of tanks used to 
transport chemical, petroleum or food grade cargos. This part does not 
apply to facilities that clean only the exteriors of transportation 
equipment. Operations which may be subject to this part typically are 
reported under a wide variety of Standard Industrial Classification 
(SIC) codes. Several of the most common SIC codes include: SIC 7699, SIC 
4741, or SIC 4491 (1987 SIC Manual).
    (b) This part is not applicable to the following discharges:
    (1) Wastewaters associated with tank cleanings operated in 
conjunction with other industrial, commercial, or Publicly Owned 
Treatment Works (POTW) operations, provided that the cleaning is limited 
to tanks that previously contained raw materials, by-products, or 
finished products that are associated with the facility's on-site 
processes.
    (2) Wastewaters resulting from cleaning the interiors of drums, 
intermediate bulk containers, or closed-top hoppers.
    (3) Wastewater from a facility that discharges less than 100,000 
gallons per year of transportation equipment cleaning process 
wastewater.



Sec.  442.2  General definitions.

    (a) In addition to the general definitions and abbreviations at 40 
CFR part 401, the following definitions shall apply to this part:
    Chemical cargos mean, but are not limited to, the following: latex, 
rubber, plastics, plasticizers, resins, soaps, detergents, surfactants, 
agricultural chemicals and pesticides, hazardous waste, organic 
chemicals including: alcohols, aldehydes, formaldehydes, phenols, 
peroxides, organic salts, amines, amides, other nitrogen compounds,

delivery, or discharge of the transported cargo. Heels may also be 
referred to as container residue, residual materials or residuals.
    Intermediate bulk container (``IBC'' or ``Tote'') means a completely 
enclosed storage vessel used to hold liquid, solid, or gaseous 
commodities or cargos which are in direct contact with the container 
interior. IBCs may be loaded onto flat beds for either truck or rail 
transport, or onto ship decks for water transport. IBCs are portable 
containers with 450 liters (119 gallons) to 3000 liters (793 gallons) 
capacity. IBCs are also commonly referred to as totes or tote bins.
    Intermodal tank container means a completely enclosed storage vessel 
used to hold liquid, solid, or gaseous commodities or cargos which come 
in direct contact with the tank interior. Intermodal tank containers may 
be loaded onto flat beds for either truck or rail transport, or onto 
ship decks for water transport. Containers larger than 3000 liters 
capacity are considered intermodal tank containers. Containers smaller 
than 3000 liters capacity are considered IBCs.
    Ocean/sea tanker means a self or non-self-propelled vessel 
constructed or adapted to transport liquid, solid or gaseous commodities 
or cargos in bulk in cargo spaces (or tanks) through oceans and seas, 
where the commodity or cargo carried comes in direct contact with the 
tank interior. There are no maximum or minimum vessel or tank volumes.
    On-site means within the contiguous and non-contiguous established 
boundaries of a facility.
    Petroleum cargos mean products of the fractionation or straight 
distillation of crude oil, redistillation of unfinished petroleum 
derivatives, cracking, or other refining processes. For purposes of this 
rule, petroleum cargos also include products obtained from the refining 
or processing of natural gas and coal. For purposes of this rule, 
specific examples of petroleum products include but are not limited to: 
asphalt; benzene; coal tar; crude oil; cutting oil; ethyl benzene; 
diesel fuel; fuel additives; fuel oils; gasoline; greases; heavy, 
medium, and light oils; hydraulic fluids, jet fuel; kerosene; liquid 
petroleum gases (LPG) including butane and propane; lubrication oils; 
mineral spirits; naphtha; olefin, paraffin, and other waxes; tall oil; 
tar; toluene; xylene; and waste oil.
    Pollution Prevention Allowable Discharge for this subpart means the 
quantity of/concentrations of pollutants in wastewaters being discharged 
to publicly owned treatment works after a facility has demonstrated 
compliance with the Pollutant Management Plan provisions in Sec.  
442.15(b), Sec.  442.16(b), Sec.  442.25(b), or Sec.  442.26(b) of this 
part.
    Prerinse/presteam means a rinse, typically with hot or cold water, 
performed at the beginning of the cleaning sequence to remove residual 
material from the tank interior.
    Presolve wash means the use of diesel, kerosene, gasoline, or any 
other type of fuel or solvent as a tank interior cleaning solution.

[[Page 450]]

    Rail Tank Car means a completely enclosed storage vessel pulled by a 
locomotive that is used to transport liquid, solid, or gaseous 
commodities or cargos over railway access lines. A rail tank car storage 
vessel may have one or more storage compartments and the stored 
commodities or cargos come in direct contact with the tank interior. 
There are no maximum or minimum vessel or tank volumes.
    Tank barge means a non-self-propelled vessel constructed or adapted 
primarily to carry liquid, solid or gaseous commodities or cargos in 
bulk in cargo spaces (or tanks) through rivers and inland waterways, and 
may occasionally carry commodities or cargos through oceans and seas 
when in transit from one inland waterway to another. The commodities or 
cargos transported are in direct contact with the tank interior. There 
are no maximum or minimum vessel or tank volumes.
    Tank truck means a motor-driven vehicle with a completely enclosed 
storage vessel used to transport liquid, solid or gaseous materials over 
roads and highways. The storage vessel or tank may be detachable, as 
with tank trailers, or permanently attached. The commodities or cargos 
transported come in direct contact with the tank interior. A tank truck 
may have one or more storage compartments. There are no maximum or 
minimum vessel or tank volumes. Tank trucks are also commonly referred 
to as cargo tanks or tankers.
    Transportation equipment cleaning (TEC) process wastewater means all 
wastewaters associated with cleaning the interiors of tanks including: 
tank trucks; rail tank cars; intermodal tank containers; tank barges; 
and ocean/sea tankers used to transport commodities or cargos that come 
into direct contact with the interior of the tank or container. At those 
facilities that clean tank interiors, TEC process wastewater also 
includes wastewater generated from washing vehicle exteriors, equipment 
and floor washings, TEC-contaminated stormwater, wastewater prerinse 
cleaning solutions, chemical cleaning solutions, and final rinse 
solutions. TEC process wastewater is defined to include only wastewater 
generated from a regulated TEC subcategory. Therefore, TEC process 
wastewater does not include wastewater generated from cleaning hopper 
cars, or from food grade facilities discharging to a POTW. Wastewater 
generated from cleaning tank interiors for purposes of shipping products 
(i.e., cleaned for purposes other than maintenance and repair) is 
considered TEC process wastewater. Wastewater generated from cleaning 
tank interiors for the purposes of maintenance and repair on the tank is 
not considered TEC process wastewater. Facilities that clean tank 
interiors solely for the purposes of repair and maintenance are not 
regulated under this part.
    (b) The parameters regulated in this part and listed with approved 
methods of analysis in Table IB at 40 CFR 136.3, are defined as follows:

Sec.  444.10  Applicability.

    (a) The provisions of this part apply only to that portion of 
wastewater discharges that are associated with Commercial Hazardous 
Waste Combustor (CHWC) wastewater.
    (b) The discharge from a CHWC of wastewater that is not CHWC 
wastewater, may be subject to other applicable provisions of EPA's CWA 
effluent guidelines and standards regulations at subchapter N of Title 
40 of the Code of Federal Regulations.

[[Page 464]]



Sec.  444.11  Definitions.

    As used in this part the general definitions and abbreviations in 40 
CFR part 401 shall apply.
    Commercial hazardous waste combustor means any thermal unit, except 
a cement kiln, that is subject either to 40 CFR part 264, subpart O; 40 
CFR part 265, subpart O; or 40 CFR part 266, subpart H if the thermal 
unit burns RCRA hazardous wastes received from off-site for a fee or 
other remuneration in the following circumstances. The thermal unit is a 
commercial hazardous waste combustor if the off-site wastes are 
generated at a facility not under the same corporate structure or 
subject to the same ownership as the thermal unit and
    (1) The thermal unit is burning wastes that are not of a similar 
nature to wastes being burned from industrial processes on site or
    (2) There are no wastes being burned from industrial processes on 
site. Examples of wastes of a ``similar nature'' may include the 
following: Wastes generated in industrial operations whose wastewaters 
are subject to the same provisions in 40 CFR subchapter N or wastes 
burned as part of a product stewardship activity. The term commercial 
hazardous waste combustor includes the following facilities: a facility 
that burns exclusively waste received from off-site; and, a facility 
that burns both wastes generated on-site and wastes received from off-
site. Facilities that may be commercial hazardous waste combustors 
include hazardous waste incinerators, rotary kiln incinerators, lime 
kilns, lightweight aggregate kilns, and boilers. A facility not 
otherwise a commercial hazardous waste combustor is not a commercial 
hazardous waste combustor if it burns RCRA hazardous waste for 
charitable organizations, as a community service or as an accommodation 
to local, state or government agencies so long as the waste is burned 
for no fee or other remuneration.
    Commercial hazardous waste combustor wastewater means wastewater 
attributable to commercial waste combustion operations, but includes 
only wastewater from air pollution control systems and water used to 
quench flue gas or slag generated as a result of commercial hazardous 
waste combustor operations.
    Off-site means outside the boundaries of a facility.
    On-site means within the boundaries of a facility.
    Parameters are defined as Parameters at 40 CFR 136.2 in Table 1B, 
which also cites the approved methods of analysis.
    (1) Arsenic means total arsenic, Parameter 6.
    (2) Cadmium means total cadmium, Parameter 12.
    (3) Chromium means total chromium, Parameter 19.
    (4) Copper means total copper, Parameter 22.
    (5) Lead means total lead, Parameter 32.
    (6) Mercury means total mercury, Parameter 35.
    (7) pH means hydrogen ion, Parameter 28.
    (8) Silver means total silver, Parameter 62.
    (9) Titanium means total titanium, Parameter 72.
    (10) TSS means total suspended solids, Parameter 55.
    (11) Zinc means total zinc, Parameter 75.
    POTW means a publicly owned treatment works.



Sec.  444.12  Monitoring requirements.

    (a) Both direct and indirect discharges must monitor to establish 
compliance with their limitations and standards. Thus, all the permits 
of all direct dischargers must include requirements to monitor, 
according to EPA-approved test procedures, each pollutant limited in the 
permit, the volume of effluent discharged from each outfall, and other 
appropriate measurements subject to notification requirements. See 40 
CFR 122.44(i). EPA's pretreatment regulations similarly require indirect 
dischargers to monitor to demonstrate compliance with pretreatment 
standards. See 40 CFR 403.12(g).
    (b) Incorporation by reference:
    (1) Compliance with the monitoring requirements may be accomplished 
using approved test procedures listed in the table to this paragraph. 
Most of these test procedures have previously been incorporated by 
reference at 40

[[Page 465]]

CFR 136.3(a), Table IB. The test procedures for the regulated pollutants 
(arsenic, cadmium, chromium (total), copper, pH, lead, mercury, TSS, 
silver, titanium, and zinc) listed in the table to this paragraph are 
also incorporated by reference into this regulation. The full texts of 
the test procedures listed in this paragraph are available from the 
sources indicated in paragraph (b)(2) of this section. In addition to 
those test procedures incorporated by reference at 40 CFR 136.3(a), 
Table IB, you may also use EPA Method 200.8, ``Determination of Trace 
Elements in Water and Wastes by Inductively Coupled Plasma-Mass 
Spectrometry,'' from ``Methods for Determination of Metals in 
Environmental Samples--Supplement I,'' EPA-600/R-94-111, May 1994, and 
ASTM Method D 5673-96, ``Standard Test Method for Elements in Water by 
Inductively Coupled Plasma--Mass Spectrometry,'' from 1999 Annual Book 
of ASTM Standards, for determination of arsenic, cadmium, chromium 
(total), copper, lead, silver, and zinc. The full texts of these methods 
are incorporated by reference into this regulation and may be obtained 
from the sources identified in paragraph (b)(2) of this section.

  ed. (1990).
\4\ For the determination of total metals the sample is not filtered before processing. A digestion procedure is
  required to solubilize suspended material and to destroy possible organic-metal complexes. Two digestion
  procedures are given in ``Methods for Chemical Analysis of Water and Wastes, 1979 and 1983''. One (Section
  4.1.3), is a vigorous digestion using nitric acid. A less vigorous digestion using nitric and hydrochloric
  acids (Section 4.1.4) is preferred; however, the analyst should be cautioned that this mild digestion may not
  suffice for all samples types. Particularly, if a colorimetric procedure is to be employed, it is necessary to
  ensure that all organo-metallic bonds be broken so that the metal is in a reactive state. In those situations,
  the vigorous digestion is to be preferred making certain that at no time does the sample go to dryness.
  Samples containing large amounts of organic materials may also benefit by this vigorous digestion, however,
  vigorous digestion with concentrated nitric acid will convert antimony and tin to insoluble oxides and render
  them unavailable for analysis. Use of ICP/AES as well as determinations for certain elements such as antimony,
  arsenic, the noble metals, mercury, selenium, silver, tin, and titanium require a modified sample digestion
  procedure and in all cases the method write-up should be consulted for specific instructions and/or cautions.
  Note.--If the digestion procedure for direct aspiration AA included in one of the other approved references is
  different than the above, the EPA procedure must be used.
Dissolved metals are defined as those constituents which will pass through a 0.45 micron membrane filter.
  Following filtration of the sample, the referenced procedure for total metals must be followed. Sample
  digestion of the filtrate for dissolved metals (or digestion of the original sample solution for total metals)
  may be omitted for AA (direct aspiration or graphite furnace) and ICP analyses, provided the sample solution
  to be analyzed meets the following criteria:
a. Has a low COD (<20)
b. Is visibly transparent with a turbidity measurement of 1 NTU or less
c. Is colorless with no perceptible odor, and
d. Is of one liquid phase and free of particulate or suspended matter following acidification.

\12\ Approved methods for the analysis of silver in industrial wastewaters at concentrations of 1 mg/L and above
  are inadequate where silver exists as an inorganic halide. Silver halides such as the bromide and chloride are
  relatively insoluble in reagents such as nitric acid but are readily soluble in an aqueous buffer of sodium
  thiosulfate and sodium hydroxide to pH of 12. Therefore, for levels of silver above 1 mg/L, 20 mL of sample
  should be diluted to 100 mL by adding 40 mL each of 2 M Na2S2O3 and NaOH. Standards should be prepared in the
  same manner. For levels of silver below 1 mg/L the approved method is satisfactory.

    (a) As defined more specifically in each subpart and except as 
provided in paragraphs (b) through (h) of this section, this part 
applies to discharges of wastewater from landfill units.
    (b) The provisions of this part do not apply to wastewater 
discharges from land application or land treatment units, surface 
impoundments, underground injection wells, waste piles, salt dome 
formations, salt bed formations, underground mines or caves as these 
terms are defined in 40 CFR 257.2 and 260.10.
    (c) The provisions of this part do not apply to wastewater generated 
off-site of a landfill facility, including wastewater generated off-site 
from washing vehicles or from waste transfer stations.
    (d) The provisions of this part do not apply to discharges of 
contaminated ground water or wastewater from recovery pumping wells.
    (e) This part does not apply to discharges of landfill wastewater 
from landfills operated in conjunction with other industrial or 
commercial operations when the landfill only receives wastes generated 
by the industrial or commercial operation directly associated with the 
landfill.
    (f) This part does not apply to discharges of landfill wastewater 
from landfills operated in conjunction with other industrial or 
commercial operations when the landfill receives wastes generated by the 
industrial or commercial operation directly associated with the landfill 
and also receives other wastes provided the other wastes received for 
disposal are generated by a facility that is subject to the same 
provisions in 40 CFR subchapter N as the industrial or commercial 
operation or the other wastes received are of similar nature to the 
wastes generated by the industrial or commercial operation.
    (g) This part does not apply to landfills operated in conjunction 
with Centralized Waste Treatment (CWT) facilities subject to 40 CFR part 
437 so long as the CWT facility commingles the landfill wastewater with 
other non-landfill wastewater for discharge. A landfill directly 
associated with a CWT facility is subject to this part if the CWT 
facility discharges landfill wastewater separately from other CWT 
wastewater or commingles the wastewater from its landfill only with 
wastewater from other landfills.

[[Page 470]]

    (h) This part does not apply to landfills operated in conjunction 
with other industrial or commercial operations when the landfill 
receives wastes from public service activities so long as the company 
owning the landfill does not receive a fee or other remuneration for the 
disposal service.

come in direct contact with landfill wastes, the waste handling and 
treatment areas, or landfill wastewater that is defined in paragraph (f) 
of this section. Non-contaminated storm water includes storm water which 
flows off the cap, cover, intermediate cover, daily cover, and/or final 
cover of the landfill.
    (h) Off-site means outside the boundaries of a facility.
    (i) On-site means within the boundaries of a facility.
    (j) Public service means the provision of landfill waste disposal 
services to individual members of the general public, publicly-owned

Sec.  449.20  Monitoring, reporting and recordkeeping requirements.

    (a) Demonstrating compliance with the ADF collection requirement for 
dischargers subject to NSPS collection requirements in Sec.  449.11. 
Except as provided in 40 CFR 125.30 through 125.32, an individual 
permittee shall select a procedure under either paragraphs (a)(1), (2), 
or (3) of this section in its permit application as the procedure for 
the permittee to demonstrate compliance with the applicable collection, 
reporting and recordkeeping requirements of this Part. A procedure 
selected by the permittee under paragraph (a)(2) of this section may be 
included in the permit only with the Director's approval, as described 
in paragraph (a)(2) of this section. For general permits, use of 
alternative methods for determining compliance with the ADF collection 
requirement for dischargers subject to NSPS collection requirements in 
this part will be at the discretion of the Director.

[[Page 477]]

    (1) The permittee shall maintain records to demonstrate, and certify 
annually, that it is operating and maintaining one or more centralized 
deicing pads. This technology shall be operated and maintained according 
to the technical specifications set forth in paragraphs (a)(1)(i) 
through (iv) of this section. For both individual and general permits, 
these technical specifications shall be expressly set forth as 
requirements in the permit. The permittee's demonstration and valid 
certification are sufficient to meet the applicable NSPS collection 
requirement without the permittee having to determine the numeric 
percentage of available ADF collected.
    (i) Each centralized deicing pad shall be sized and sited in 
accordance with all applicable FAA advisory circulars.
    (ii) Drainage valves associated with the centralized deicing pad 
shall be activated before deicing activities commence, to collect 
available ADF.
    (iii) The centralized deicing pad and associated collection 
equipment shall be installed and maintained per any applicable 
manufacturers' instructions, and shall be inspected, at a minimum, at 
the beginning of each deicing season to ensure that the pad and 
associated equipment are in working condition.
    (iv) All aircraft deicing shall take place on a centralized deicing 
pad, with the exception of defrosting and deicing for safe taxiing.
    (2) Alternative technology or specifications. (i) An individual 
permit (or a general permit at the discretion of the Director) may allow 
one of the following alternative procedures for demonstrating compliance 
with its collection requirement, instead of the procedure in paragraph 
(a)(1) of this section. The permittee must submit all information and 
documentation necessary to support this request. An individual permittee 
may request this alternative procedure in its initial permit application 
or permit renewal application. During the term of an individual permit, 
the permittee may also request this alternative procedure as a permit 
modification, subject to the requirements and procedures at 40 CFR 
122.62 and 40 CFR part 124. If the Director determines, in his or her 
discretion, that the requested alternative procedure will achieve the 
collection requirement in the permit, the Director shall approve the 
request:
    (A) The use of a different ADF collection technology from the 
centralized deicing pad technology specified in paragraph (a)(1) of this 
section; or
    (B) The use of the same ADF collection technology, but with 
different specifications for operation and/or maintenance.
    (ii) Pollution prevention credit. A permittee may apply for, and 
obtain, full or partial credit towards compliance with the available ADF 
collection requirement. To obtain credit the permittee must demonstrate 
to the Director's satisfaction that it employs a pollution prevention 
technique that reduces the volume of, or quantity of, pollutants in, 
available ADF. The credit shall be equivalent to the demonstrated 
reduction, as determined by the Director.
    (iii) The Director shall set forth technical specifications for 
proper operation and maintenance of the chosen collection technology, as 
appropriate, and compliance with these technical specifications must be 
required by the permit. The permit shall also require the permittee to 
maintain records sufficient to demonstrate compliance with these 
requirements. This demonstration constitutes compliance by the permittee 
with the percent capture requirement without the permittee having to 
determine the numeric percentage of ADF that it has collected. Before 
the Director may approve an alternate technology under this subsection, 
the permittee must demonstrate to the Director's satisfaction that the 
alternate technology will achieve the applicable percent capture 
requirement.
    (3) The permittee shall maintain records, by means deemed acceptable 
by the Director, and report at a frequency determined by the Director, 
on the volume of ADF sprayed and the amount of available ADF collected 
in order to determine the compliance with the collection requirement.
    (b) Monitoring requirements--(1) COD limitation. Permittees subject 
to the ADF collection and discharge requirements specified in Sec.  
449.11 must conduct effluent monitoring to demonstrate compliance with 
the COD limitation

[[Page 478]]

for all ADF that is collected. Compliance must be demonstrated at the 
location where the effluent leaves the on-site treatment system utilized 
for meeting these requirements and before commingling with any non-
deicing discharge. Effluent samples must be collected following the 
protocol in Appendix A to this part.
    (2) Ammonia limitation. If a permittee chooses to comply with the 
compliance alternative specified in Sec.  449.10(a) or Sec.  449.11(b), 
the permittee must conduct effluent monitoring at all locations where 
pavement deicing with a product that contains urea is occurring, prior 
to any dilution or commingling with any non-deicing discharge.
    (c) Recordkeeping. (1) The permit shall provide that the permittee 
must maintain on site, during the term of the permit, up to five years, 
records documenting compliance with paragraphs (a) through (b) of this 
section. These records include, but are not limited to, documentation of 
wastewater samples collected and analyzed, certifications, and equipment 
maintenance schedules and agreements.
    (2) At the Director's discretion, a requirement may be included in 
the permit for the permittee to collect, and maintain on site during the 
term of the permit, up to five (5) years of data on the annual volume of 
ADF used.

Subpart B [Reserved]





     Sec. Appendix A to Part 449--Sampling Protocol for Soluble COD

    This sampling protocol applies only to samples collected for use in 
measurement of COD when demonstrating compliance with the regulations 
set forth in this part. Collect a representative sample of the effluent 
from the airport deicing treatment system, based on the discharge permit 
requirements (e.g., a grab sample or a composite sample). Because only 
the COD sample is filtered, do not use in-line filters if collecting a 
sample with a compositing device.

                             A. Grab Samples

    1. Cap the container and shake the grab sample vigorously to mix it. 
Remove the plunger from a 10-milliliter (mL) or larger Luer-lock plastic 
syringe equipped with an Acrodisc Luer-lock filter containing a 1.5-
[mu]m glass fiber filter (Whatman 934-AH, or equivalent), and fill the 
syringe body with sample.
    2. Replace the plunger and filter the sample into a clean 50-mL 
screw-cap glass, plastic, or fluoropolymer bottle.

    Note: If testing is being done in the field, or with a test kit 
product (e.g., Hach Method 8000), the filtrate may be collected in the 
test kit vial or container.

    3. Additional 10-mL volumes of sample may be filtered and the 
filtrate added to the same sample bottle. This additional volume may be 
used to repeat sample analyses or to prepare Quality Control (QC) 
samples, as needed.
    4. Unless the filtered sample will be analyzed within 15 minutes, 
preserve the filtered sample with H2SO4 to pH <2. 
Cap the bottle and label with the sample number. Place in a cooler on 
ice prior to shipping.
    5. Once at the analytical laboratory, the sample must be stored at 
<=6 degrees Celsius and analyzed within 28 days of collection (see the 
requirements for COD in Table II at 40 CFR part 136).
    6. Analyze the sample using a method approved for COD in Table IB at 
40 CFR part 136.

    Note: Because this procedure is specific to this point source 
category, it does not appear by name in 40 CFR part 136.

    7. Report the sample results as Soluble COD in units of milligrams 
per liter (mg/L). There is no Chemical Abstracts Service (CAS) Registry 
Number for soluble COD.

                          B. Composite Samples

    1. If the sample will be analyzed in a fixed laboratory (as opposed 
to field testing), transfer at least 50 mL of well-mixed sample from the 
compositing device into a clean 50-mL screw-cap glass, plastic, or 
fluoropolymer bottle. Preserve the sample with 
H2SO4 to pH <2. Cap the bottle and label with the 
sample number. Place in a cooler on ice prior to shipping.
    2. Once at the analytical laboratory, the sample must be stored at 
<=6 degrees Celsius and analyzed within 28 days of collection (see the 
requirements for COD in Table II at 40 CFR part 136).
    3. Prior to analysis, remove the sample from cold storage and allow 
it to warm to room temperature. Shake the sample vigorously to mix it.
    4. Remove the plunger from a 10-mL or larger Luer-lock plastic 
syringe equipped with an Acrodisc Luer-lock filter containing a 1.5-
[mu]m glass fiber filter (Whatman 934-AH, or equivalent), and fill the 
syringe body with sample.
    5. Replace the plunger and filter the sample into a clean COD vial 
or other suitable container.
    6. Additional 10-mL volumes of sample may be filtered and the 
filtrate added to separate

[[Page 479]]

containers, as needed, to provide samples for repeat analyses or to 
prepare QC samples.
    7. Analyze the sample using a method approved for COD in Table 1B at 
40 CFR part 136.

    Note: Because this procedure is specific to this point source 
category, it does not appear by name in 40 CFR part 136.

    8. Report the sample results as Soluble COD in units of mg/L. There 
is no CAS Registry Number for soluble COD.

       Subpart B_Construction and Development Effluent Guidelines



Sec.  450.21  Effluent limitations reflecting the best practicable technology 
currently available (BPT).

    Except as provided in 40 CFR 125.30 through 125.32, any point source 
subject to this subpart must achieve, at a minimum, the following 
effluent limitations representing the degree of effluent reduction 
attainable by application of the best practicable control technology 
currently available (BPT).
    (a) Erosion and sediment controls. Design, install and maintain 
effective erosion controls and sediment controls to minimize the 
discharge of pollutants. At a minimum, such controls must be designed, 
installed and maintained to:
    (1) Control stormwater volume and velocity to minimize soil erosion 
in order to minimize pollutant discharges;
    (2) Control stormwater discharges, including both peak flowrates and 
total stormwater volume, to minimize channel and streambank erosion and 
scour in the immediate vicinity of discharge points;
    (3) Minimize the amount of soil exposed during construction 
activity;
    (4) Minimize the disturbance of steep slopes;
    (5) Minimize sediment discharges from the site. The design, 
installation and maintenance of erosion and sediment controls must 
address factors such as the amount, frequency, intensity and duration of 
precipitation, the nature of resulting stormwater runoff, and soil 
characteristics, including the range of

[[Page 480]]

soil particle sizes expected to be present on the site;
    (6) Provide and maintain natural buffers around waters of the United 
States, direct stormwater to vegetated areas and maximize stormwater 
infiltration to reduce pollutant discharges, unless infeasible;
    (7) Minimize soil compaction. Minimizing soil compaction is not 
required where the intended function of a specific area of the site 
dictates that it be compacted; and
    (8) Unless infeasible, preserve topsoil. Preserving topsoil is not 
required where the intended function of a specific area of the site 
dictates that the topsoil be disturbed or removed.
    (b) Soil stabilization. Stabilization of disturbed areas must, at a 
minimum, be initiated immediately whenever any clearing, grading, 
excavating or other earth disturbing activities have permanently ceased 
on any portion of the site, or temporarily ceased on any portion of the 
site and will not resume for a period exceeding 14 calendar days. In 
arid, semiarid, and drought-stricken areas where initiating vegetative 
stabilization measures immediately is infeasible, alternative 
stabilization measures must be employed as specified by the permitting 
authority. Stabilization must be completed within a period of time 
determined by the permitting authority. In limited circumstances, 
stabilization may not be required if the intended function of a specific 
area of the site necessitates that it remain disturbed.
    (c) Dewatering. Discharges from dewatering activities, including 
discharges from dewatering of trenches and excavations, are prohibited 
unless managed by appropriate controls.
    (d) Pollution prevention measures. Design, install, implement, and 
maintain effective pollution prevention measures to minimize the 
discharge of pollutants. At a minimum, such measures must be designed, 
installed, implemented and maintained to:
    (1) Minimize the discharge of pollutants from equipment and vehicle 
washing, wheel wash water, and other wash waters. Wash waters must be 
treated in a sediment basin or alternative control that provides 
equivalent or better treatment prior to discharge;
    (2) Minimize the exposure of building materials, building products, 
construction wastes, trash, landscape materials, fertilizers, 
pesticides, herbicides, detergents, sanitary waste and other materials 
present on the site to precipitation and to stormwater. Minimization of 
exposure is not required in cases where the exposure to precipitation 
and to stormwater will not result in a discharge of pollutants, or where 
exposure of a specific material or product poses little risk of 
stormwater contamination (such as final products and materials intended 
for outdoor use); and
    (3) Minimize the discharge of pollutants from spills and leaks and 
implement chemical spill and leak prevention and response procedures.
    (e) Prohibited discharges. The following discharges are prohibited:
    (1) Wastewater from washout of concrete, unless managed by an 
appropriate control;
    (2) Wastewater from washout and cleanout of stucco, paint, form 
release oils, curing compounds and other construction materials;
    (3) Fuels, oils, or other pollutants used in vehicle and equipment 
operation and maintenance; and
    (4) Soaps or solvents used in vehicle and equipment washing.
    (f) Surface outlets. When discharging from basins and impoundments, 
utilize outlet structures that withdraw water from the surface, unless 
infeasible.

[[Page 482]]

122.24 and appendix C of 40 CFR part 122.
    (e) Drug means any substance defined as a drug in section 201(g)(1) 
of the Federal Food, Drug and Cosmetic Act (21 U.S.C. 321).
    (f) Extralabel drug use means a drug approved under the Federal 
Food, Drug and Cosmetic Act that is not used in accordance with the 
approved label directions, see 21 CFR part 530.
    (g) Flow-through system means a system designed to provide a 
continuous water flow to waters of the United States through chambers 
used to produce aquatic animals. Flow-through systems typically use 
rearing units that are either raceways or tank systems. Rearing units 
referred to as raceways are typically long, rectangular chambers at or 
below grade, constructed of earth, concrete, plastic, or metal to which 
water is supplied by nearby rivers or springs. Rearing units comprised 
of tank systems use circular or rectangular tanks and are similarly 
supplied with water to raise aquatic animals. The term does not include 
net pens.
    (h) Investigational new animal drug (INAD) means a drug for which 
there is a valid exemption in effect under section 512(j) of the Federal 
Food, Drug, and Cosmetic Act, 21 U.S.C. 360b(j), to conduct experiments.
    (i) New animal drug application is defined in 512(b)(1) of the 
Federal Food, Drug, and Cosmetic Act (21 U.S.C 360b(b)(1)).
    (j) Net pen system means a stationary, suspended or floating system 
of nets, screens, or cages in open waters of the United States. Net pen 
systems typically are located along a shore or pier or may be anchored 
and floating offshore. Net pens and submerged cages rely on tides and 
currents to provide a continual supply of high-quality water to the 
animals in production.
    (k) Permitting authority means EPA or the State agency authorized to 
administer the National Pollutant Discharge Elimination System 
permitting program for the receiving waters into which a facility 
subject to this part discharges.

section 2(u) of the Federal Insecticide, Fungicide, and Rodenticide Act 
(7 U.S.C. 136(u)).
    (m) Real-time feed monitoring means a system designed to track the 
rate of feed consumption and to detect uneaten feed passing through the 
nets at a net pen facility. These systems may rely on a combination of 
visual observation and hardware, including, but not limited to, devices 
such as video cameras, digital scanning sonar, or upweller systems that 
allow facilities to determine when to cease feeding the aquatic animals. 
Visual observation alone from above the pens does not constitute real-
time monitoring.
    (n) Recirculating system means a system that filters and reuses 
water in which the aquatic animals are produced prior to discharge. 
Recirculating systems typically use tanks, biological or mechanical 
filtration, and mechanical support equipment to maintain high quality 
water to produce aquatic animals.

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 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,

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

[[Page 493]]

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 D_Test Methods for Pesticide Pollutants



Sec.  455.50  Identification of test procedures.

    The pesticide active ingredients to which this section applies and 
for which effluent limitations guidelines and standards are specified in 
this part are named, together with the Chemical Abstracts Service (CAS) 
number (provided to assist in identifying the pesticide active 
ingredient only) and analytical method(s) designation(s) in Table IG at 
40 CFR 136.3(a). Except as provided in 40 CFR 136.5, the discharge 
parameter values required under the Clean Water Act must be determined 
by one of the analytical methods cited and described in Table IG at 40 
CFR 136.3(a). Pesticide manufacturers may not use the analytical method 
cited in Table IB, Table IC, or Table ID of 40 CFR 136.3(a) to make 
these determinations (except where the method cited in those tables is 
identical to the method specified in Table IG at 40 CFR 136.3(a)). The 
full texts of the analytical methods cited in Table IG at 40 CFR 
136.3(a) are contained in the Methods For The Determination of 
Nonconventional Pesticides In Municipal and Industrial Wastewater, 
Volume I, EPA 821-R-93-010A (August 1993 Revision I) and Volume II, EPA 
821-R-93-010B (August 1993) (the ``Compendium''). Each pesticide 
chemical manufacturer that is required to determine discharge parameter 
values under this part using one of the analytical methods cited in 
Table IG at 40 CFR 136.3(a) must request in writing a copy of the 
Compendium from the permit authority or local control authority (as 
applicable) prior to determining such discharge parameter values, unless 
the manufacturer already has a copy.

                   Sec. Table 7 to Part 455 [Reserved]



   Sec. Table 8 to Part 455--List of Pollution Prevention Alternative 
                                Practices

    A modification to the list of practices on this table that an 
individual facility must comply with to be eligible for the pollution 
prevention alternative is allowed with acceptable justification as 
listed on this table as approved by the permit writer or control 
authority (using BPJ/BEJ) after submittal by the facility of a request 
for modification. A modification, for purposes of this table, means that 
a facility would no longer have to perform a listed practice or would 
need to comply with a modified practice. However, the modification only 
applies to the specific practice for which the modification has been 
justified and to no other listed practices. Facilities are required to 
thoroughly discuss all modifications in the on-site compliance paperwork 
as described above in the limitations and standards (Sec.  455.41(c)).
    1. Must use water conservation practices. These practices may 
include, but are not limited to using: spray nozzles or flow reduction 
devices on hoses, low volume/high pressure rinsing equipment, floor 
scrubbing machines, mop(s) and bucket(s), and counter current staged 
drum rinsing stations.
[Modification allowed when: Rinsing narrow transfer lines or piping 
where sufficient rinsing is better achieved by flushing with water.]
    2. Must practice good housekeeping:
    (a) Perform preventative maintenance on all valves and fittings and 
repair leaky valves and fittings in a timely manner;
    (b) Use drip pans under any valves or fittings where hoses or lines 
are routinely connected and disconnected, collect for reuse when 
possible; and
    (c) Perform quick cleanup of leaks and spills in outdoor bulk 
storage or process areas.
    3. Must sweep or vacuum dry production areas prior to rinsing with 
water.
    4. Must clean interiors of dry formulation equipment with dry 
carrier prior to any water rinse. The carrier material must be stored 
and reused in future formulation of the same or compatible product or 
properly disposed of as solid waste.
    5. If operating continuous overflow Department of Transportation 
(DOT) aerosol leak test baths--
    Must operate with some recirculation.
    6. If operating air pollution control wet scrubbers--
    Must operate as recirculating scrubbers (periodic blowdown is 
allowed as needed).
[Modification allowed when: Facility demonstrates that they would not be 
able to meet Resource Conservation Recovery Act or Clean Air Act (CAA) 
requirements.]

    7. When performing rinsing of raw material drums, storage drums, 
and/or shipping containers that contained liquid PAI(s) and/or inert 
ingredients for the formulation of water-based products--
    Must reuse the drum/shipping container rinsate DIRECTLY into the 
formulation at the time of formulation; or store for use in future 
formulation of same or compatible product; or use a staged drum rinsing 
station (counter current rinsing).
[Modification allowed when: the drum/shipping container holds inert 
ingredient(s) only and (1) the facility can demonstrate that, after 
using water conservation practices, the large concentration of inert 
ingredient in the formulation creates more volume than could feasibly be 
reused; or (2) the facility can demonstrate that the concentration of 
the inert in the formulation is so small that the reuse would cause a 
formulation to exceed the ranges allowed in the Confidential Statement 
of Formula (CSF) (40 CFR 158.155).]

    8. When performing rinsing of raw material drums, storage drums, 
and/or shipping containers that contained liquid PAI(s) and/or inert 
ingredients for the formulation of solvent-based products--
    Must reuse the drum/shipping container rinsate DIRECTLY into the 
formulation at the time of formulation or store for use in future 
formulation of same or compatible product.

[[Page 512]]

[Modification allowed when:

    (a) The drum/shipping container holds inert ingredient(s) only and: 
(1) The facility can demonstrate that, after using water conservation 
practices, the large concentration of inert ingredient in the 
formulation creates more volume than could feasibly be reused; or (2) 
the facility can demonstrate that the concentration of the inert in the 
formulation is so small that the reuse would cause a formulation to 
exceed the ranges allowed in the Confidential Statement of Formula (CSF) 
(40 CFR 158.155); or
    (b) Drums/shipping containers are going to a drum refurbisher/
recycler who will only accept drums rinsed with water.]
    9. Must dedicate PFPR production equipment by water-based versus 
solvent-based products. Dedicated solvent-based or water-based equipment 
may be used on a non-routine basis for non-dedicated operations; however 
the facility may not discharge the solvent/aqueous changeover rinsate as 
part of their P2 allowable discharge (i.e., the facility must achieve 
zero discharge of those process wastewater pollutants).
[Modification allowed when: Facility has installed and is using a 
solvent recovery system for the changeover rinsate (can also be used for 
other solvent recovery).]

    10. Must store the rinsate from interior rinsing (does not include 
drum/shipping container rinsate) for reuse in future formulation of same 
or compatible product.

[Modification allowed when:

    (a) Facility has evidence of biological growth or other product 
deterioration over a typical storage period;
    (b) Facility has space limitations, BUT must still store rinsates 
for most frequently produced products;
    (c) Manufacturer (or formulator contracting for toll formulating) 
has directed otherwise (i.e., send back to them or send for off-site 
disposal);
    (d) Facility is dropping registration or production of the 
formulation and there is no compatible formulation for reuse of the 
rinsates or facility can provide reasonable explanation of why it does 
not anticipate formulation of same or compatible formulation within the 
next 12 months;
    (e) Facility only performs packaging of the pesticide product from 
which interior rinsate is generated; or
    (f) Facility has demonstrated that it must use a detergent to clean 
the equipment.]

                                  Notes

    For indirect dischargers: After following the practices above, some 
wastewaters may require pretreatment prior to discharge to POTWs. See 
definition of pollution prevention allowable discharge for indirect 
dischargers (Sec.  455.41(d)).
    For direct dischargers: After following the practices above, all 
wastewaters require treatment prior to discharge directly to the 
nation's waters. See definition of pollution prevention allowable 
discharge for direct dischargers (Sec.  455.41(e)).
    Additional information and guidance on implementing these P2 
practices as well as evaluating compliance with these practices will be 
available in a P2 Guidance Manual for the PFPR Industry.

    Sec. Table 10 to Part 455--List of Appropriate Pollution Control 
                              Technologies

    This table contains those pollutant control technologies, such as 
hydrolysis, chemical oxidation, precipitation and activated carbon 
adsorption, which have been used for estimating compliance costs on a 
PAI specific basis. In general, these treatment technologies have been 
determined to be effective in treating pesticide containing wastewaters 
in literature, in bench or pilot scale treatability studies or in the 
Pesticide Manufacturing effluent guidelines. These are the same 
technologies that are presented as part of the Universal Treatment 
System. However, these technologies are PAI specific and may need to be 
used in conjunction with one another to provide treatment for all PAIs 
used at a facility over a period of time. In addition, facilities may 
experience difficulties treating wastewaters that contain emulsions, 
therefore, ``appropriate'' treatment for emulsified wastewaters must 
include an emulsion breaking step. For PAIs whose technology is listed 
as ``Pollution Prevention'', the permitting authority/control authority 
can determine if additional treatment is necessary through best 
professional judgement/best engineering judgement, respectively.

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:

                           General Provisions



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 535]]

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:

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.

[[Page 567]]

    (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.
    (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.

[[Page 568]]



Sec.  463.3  Monitoring and reporting requirements.

comes in contact with the plastic product during finishing.



Sec.  463.31  Specialized definitions.

    For the purpose of this subpart:
    (a) The ``average process water usage flow rate'' of a finishing 
water process in liters per day is equal to the volume of process water 
(liters) used per year by a process divided by the number of days per 
year the process operates. The ``average process water usage flow rate'' 
for a plant with more than one plastics molding and forming process that 
uses finishing water is the sum of the ``average process water usage 
flow rates'' for the finishing processes.
    (b) The ``volume of process water used per year'' is the volume of 
process water that flows through a finishing water process and comes in 
contact with the plastics product over a period of one year.



Sec.  463.32  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 effluent 
limitations guidelines (i.e., mass of pollutant discharged) representing 
the degree of effluent reduction attainable by the application of the 
best practicable control technology currently available, which are 
calculated by multiplying the average process water usage flow rate for 
the finishing water processes at a point source times the following 
pollutant concentrations:

                           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 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

[[Page 574]]

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 Sec. Sec.  
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 
Sec. Sec.  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 Sec. Sec.  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 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.  464.23  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 discharges, 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 Sm\3\ 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 594]]

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

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.
    (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.

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.
    (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

[[Page 637]]

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 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

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.

[[Page 638]]

    (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.

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 calendar 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 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)

Sec.  467.27  Effluent limitations representing the degree of effluent 
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 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:

using an air pollution control device to remove particulates and fumes 
from air above a pickling bath by entraining the pollutants in water.
    (m) The term ``pickling rinse'' shall mean a rinse, other than an 
alkaline cleaning rinse, through which a workpiece is processed. A rinse 
consisting of a series of rinse tanks is considered as a single rinse.
    (n) The term ``off-kilogram (off-pound)'' shall mean the mass of 
copper or copper alloy removed from a forming or ancillary operation at 
the end of a process cycle for transfer to a different machine or 
process.
    (o) The term ``rolling'' shall mean the reduction in the thickness 
or diameter of a workpiece by passing it between rollers.
    (p) The term ``solution heat treatment'' shall mean the process 
introducing a workpiece into a quench bath for the purpose of heat 
treatment following rolling, drawing or extrusion.
    (q) The term ``spent lubricant'' shall mean water or an oil-water 
mixture which is used in forming operations to reduce friction, heat and 
wear and ultimately discharged.

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

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.

[[Page 705]]

    (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.
    (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,

[[Page 706]]

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

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 
introduces regulated wastewaters to the POTW throughout the operating 
hours of the facility, except for infrequent shutdowns for maintenance,

    (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 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 0.050mg/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

[[Page 732]]

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.
    (e) Drawing spent neat oils--subpart C--NSPS. There shall be no 
discharge of process wastewater pollutants.
    (f) Drawing spent emulsions.

    (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 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.

    (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.

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., 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--BAT. (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.

[[Page 804]]

    (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--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 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, 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 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.

    (1) The authority to require compliance by any person who uses or 
disposes of sewage sludge with standards for sludge use or disposal 
issued under section 405(d) of the CWA, including compliance by federal 
facilities;
    (2) The authority to issue permits that apply, and ensure compliance 
with, the applicable requirements of section 405 of the Clean Water Act 
to any POTW or other treatment works treating domestic sewage, and 
procedures for issuance of such permits;
    (3) Provisions for regulating the use or disposal of sewage sludge 
by non-permittees;
    (4) The authority to take actions to protect public health and the 
environment from any adverse effects that may occur from toxic 
pollutants in sewage sludge; and
    (5) The authority to abate violations of the State sludge program, 
including civil and criminal penalties and other ways and means of 
enforcement. Indian Tribes can satisfy criminal enforcement authority 
requirements under Sec.  501.25.
    (d) In addition, any complete State Sludge Management Program 
submitted for approval under this part must have authority to regulate 
all sewage sludge management activities subject to 40 CFR part 503, 
unless the State is applying for partial sludge program approval in 
accordance with

[[Page 822]]

paragraph (m) of this section. The State sludge management program must 
include authority to regulate all Federal facilities in the State. 
Sludge management activities must include as applicable:
    (1) Land application;
    (2) Landfilling in a Municipal Solid Waste Landfill regulated under 
40 CFR part 258;
    (3) Incineration;
    (4) Surface disposal; and
    (5) Any other sludge use or disposal practices that may subsequently 
be regulated by 40 CFR part 503.
    (e) The Administrator will approve State programs which conform to 
the applicable requirements of this part.
    (f)(1) Upon approval of a State program, the Administrator will 
suspend the issuance of federal permits for those activities subject to 
the approved State program. After program approval EPA will retain 
jurisdiction over any permits (including general permits) which it has 
issued unless arrangements have been made with the State in the 
Memorandum of Agreement for the State to assume responsibility for these 
permits. Retention of jurisdiction will include the processing of any 
permit appeals, modification requests, or variance requests; the conduct 
of inspections, and the receipt and review of self-monitoring reports. 
If any permit appeal, modification request, or variance request is not 
finally resolved when the federally issued permit expires, EPA may, with 
the consent of the State, retain jurisdiction until the matter is 
resolved.
    (2) The procedures outlined in the preceding paragraph (f)(1) of 
this section for the suspension of permitting authority and transfer of 
existing permits will also apply when EPA approves an Indian Tribe's 
application to operate a State sludge management program and a State was 
the authorized permitting authority under Sec.  501.13 for sludge 
management activities within the scope of the newly approved program. 
The authorized State will retain jurisdiction over its existing permits 
as described in paragraph (f)(1) of this section absent a different 
arrangement stated in the Memorandum of Agreement executed between EPA 
and the Tribe.
    (g) Notwithstanding approval of a State sludge program, EPA has the 
authority to take enforcement actions for any violations of this part or 
sections 405 or 309 of the CWA.
    (h) Any State program approved by the Administrator shall at all 
times be conducted in accordance with the requirements of this part.
    (i) Nothing in this part precludes a State or political subdivision 
thereof, or interstate agency, from adopting or enforcing requirements 
established by State or local law that are more stringent or more 
extensive than those required in this part or in any other federal 
statute or regulation.
    (j) Nothing in this part precludes a State from operating a program 
with a greater scope of coverage than that required under this part. If 
an approved State program has greater scope of coverage than required by 
federal law, the additional coverage is not part of the federally 
approved program.
    (k) Sections 106 (a) and (d) of the Marine Protection, Research, and 
Sanctuaries Act (MPRSA), 33 U.S.C. 1416, generally preclude States from 
regulating or issuing permits for ocean dumping. Nothing in this 
regulation is intended to confer on the States the authority to engage 
in the regulation or permitting of ocean dumping in contravention of the 
provisions of sections 106 (a) and (d) of the MPRSA.
    (l) The Administrator may allow a State sewage sludge management 
agency to assign portions of its program responsibilities to local 
agencies, provided that:
    (1) No assignment is made to a local agency which owns or operates a 
POTW or other facility that treats or disposes of sewage sludge;
    (2) The program description required by Sec.  501.12 of this part 
identifies any assignment of program responsibilities to the local 
agency(ies), describes the capabilities of the local agency to carry out 
assigned functions, and includes copies of any documents which execute 
the assignment and an agreement between the State sewage sludge 
management agency and the local agency(ies) defining their respective 
program responsibilities;
    (3) The Attorney General's Statement required by Sec.  501.13 of 
this part

[[Page 823]]

states that any assignment of program responsibilities to the local 
agency(ies) described in the program description is valid under State 
law and that State and local law do not otherwise prohibit the local 
agency(ies) from executing the program responsibilities assigned by the 
State sewage sludge management agency;
    (4) The Memorandum of Agreement (MOA) required by Sec.  501.14 of 
this part includes adequate provisions for the State sewage sludge 
management agency's oversight of the program responsibilities assigned 
to the local agency(ies);
    (5) The State sewage sludge management agency retains all 
responsibility for the program reporting required by Sec.  501.21 of 
this part and for all other activities required by this part or by the 
MOA related to EPA oversight of the State's approved program; and
    (6) The State sewage sludge management agency retains full authority 
and ultimate responsibility for administering all aspects of the State's 
approved program in accordance with the requirements of this part and 
the MOA.
    (m) A State whose sludge management program has not been approved 
under this part may submit to the Regional Administrator an application 
for approval of a partial sewage sludge program. The following are the 
requirements for approval of a partial program:
    (1) A partial program submission must constitute a complete 
management program covering one or more categories of sewage sludge use 
or disposal. The program must also apply to anyone engaged in the sewage 
sludge use or disposal practice that is the subject of the partial 
program. A complete management program is one that provides for the 
issuance of permits, the monitoring of compliance and, in the event of 
violations, possible enforcement action.
    (2) The partial program submission must also address the following 
requirements:
    (i) The Attorney General's Statement, in addition to the information 
required by Sec.  501.13, must clearly explain the jurisdiction of the 
administering agency or department;
    (ii) The program description, in addition to the information 
required by Sec.  501.12, must explain how the program will operate, 
including which use and disposal practice(s) the State will cover. The 
program description must also explain the relationship and coordination 
between the proposed partial sewage sludge program and that part of the 
program for which EPA will remain the permitting authority, including a 
discussion of the division of permitting, enforcement, and compliance 
monitoring responsibilities between the State and EPA; and
    (iii) The Memorandum of Agreement between EPA and the State, in 
addition to the information required by Sec.  501.14, must set out the 
responsibilities of EPA and the State in administering the partial 
program, including specific provisions for transfer of information and 
determination of which users or disposers of sewage sludge are included 
in the partial program.

sludge management program that has

[[Page 826]]

been in existence for a minimum of two years and is at least as 
stringent as the program for which the State is seeking authorization; 
and
    (3) An estimate of the sources and amounts of funding for the first 
two years after approval to meet the costs listed in paragraph (b)(2) of 
this section, except where a State is seeking authorization for an 
established sewage sludge management program that has been in existence

Indian reservation in accordance with Sec.  501.13, a description of how 
responsibility for pending permit applications, existing permits, and 
supporting files will be transferred from the State to the eligible 
Indian Tribe. To the maximum extent practicable, this should include a 
Memorandum of Agreement negotiated between the State and the Indian 
Tribe addressing the arrangements for such transfer.

[54 FR 18786, May 2, 1989, as amended at 58 FR 67984, Dec. 22, 1993; 59 
FR 64346, Dec. 14, 1994; 63 FR 45124, Aug. 24, 1998]



Sec.  501.13  Attorney General's statement.

    Any State that seeks to administer a program under this part shall 
submit a statement from the State Attorney General (or the attorney for 
those State or interstate agencies which have independent legal counsel) 
that the laws of the State, or an interstate compact, provide adequate 
authority to carry out the program described under Sec.  501.12 and to 
meet the requirements of this part. This statement shall include 
citations to the specific statutes, administrative regulations, and, 
where appropriate, judicial decisions which demonstrate adequate 
authority. State statutes and regulations cited by the State Attorney 
General or independent legal counsel shall be in the form of lawfully 
adopted State statutes and regulations at the time the statement is 
signed and shall be fully effective by the time the program is approved. 
To qualify as ``independent legal counsel'' the attorney signing the 
statement required by this section must have full authority to 
independently represent the State agency in court on all matters 
pertaining to the State program. If a State (which is not an Indian 
Tribe) seeks to carry out the program on Indian lands, the statement 
shall include an appropriate opinion and analysis of the State's legal 
authority.

[54 FR 18786, May 2, 1989, as amended at 58 FR 67984, Dec. 22, 1993]



Sec.  501.14  Memorandum of Agreement with the Regional Administrator.

    (a) Any State that seeks to administer a program under this part 
must submit a Memorandum of Agreement. The Memorandum of Agreement must 
be executed by the State Program Director and the Regional Administrator 
and will become effective when approved by the Regional Administrator.

[[Page 827]]

In addition to meeting the requirements of paragraph (b) of this 
section, the Memorandum of Agreement may include other terms, 
conditions, or agreements consistent with this part and relevant to the 
administration and enforcement of the State's regulatory program. The 
Administrator will not approve any Memorandum of Agreement which 
contains provisions which restrict EPA's exercise of its oversight 
responsibility.
    (b) The Memorandum of Agreement shall include the following:
    (1)(i) Provisions for the prompt transfer from EPA to the State of 
pending permit applications applicable to the State program (or portion 
of the State program for which the State seeks approval) and any other 
information relevant to program operation not already in the possession 
of the State Director (e.g., support files for permit issuance, 
compliance reports, etc.). If existing permits are transferred from EPA 
to the State for administration, the Memorandum of Agreement must 
contain provisions specifying a procedure for transferring the 
administration of these permits. If a State lacks the authority to 
directly administer permits issued by the federal government, a 
procedure may be established to transfer responsibility for these 
permits.
    (ii) Where a State has been authorized by EPA to issue permits in 
accordance with Sec.  501.13 on the Federal Indian reservation of the 
Indian Tribe seeking program approval, provisions describing how the 
transfer of pending permit applications, permits, and any other 
information relevant to the program operation not already in the 
possession of the Indian Tribe (support files for permit issuance, 
compliance reports, etc.) will be accomplished.
    (2) Provisions specifying classes and categories of permit 
applications, draft permits, and proposed permits that the State will 
send to the Regional Administrator for review, comment and, where 
applicable, objection. These provisions must follow the permit review 
procedures set forth in 40 CFR 123.44.
    (3) The Memorandum of Agreement must also specify the extent to 
which EPA will waive its right to review, object to, or comment upon 
State-issued permits.
    (4) Whenever a waiver is granted under paragraph (3) of this 
section, the Memorandum of Agreement shall contain a statement that the 
Regional Administrator retains the right to terminate the waiver as to 
future permit actions, in whole or in part, at any time by sending the 
State Director written notice of termination.
    (5) Provisions specifying the frequency and content of reports, 
documents and other information which the State is required to submit to 
EPA. The State shall allow EPA to routinely review State records, 
reports, and files relevant to the administration and enforcement of the 
approved program. State reports may be combined with grant reports where 
appropriate. The procedures shall implement the requirements of Sec.  
501.21.
    (c) The Memorandum of Agreement must also provide for the following:
    (1) The circumstances in which the State must promptly send notices, 
draft permits, final permits, or related documents to the Regional 
Administrator; and
    (2) Provisions on the State's compliance monitoring and enforcement 
program, including:
    (i) Provisions for coordination of compliance monitoring activities 
by the State and by EPA. These may specify the basis on which the 
Regional Administrator will select facilities or activities within the 
State for EPA inspection; and
    (ii) Procedures to assure coordination of enforcement activities.
    (3) When appropriate, provisions for joint processing of permits by 
the State and EPA for facilities or activities which require permits 
from both EPA and the State under different programs (see for example 40 
CFR 124.4).
    (4) Provisions for modification of the Memorandum of Agreement in 
accordance with this part.
    (5) Provisions for modification of the Memorandum of Agreement in 
accordance with this part.
    (d) The Memorandum of Agreement, the annual program grant and the 
State/EPA Agreement should be consistent. If the State/EPA Agreement 
indicates that a change is needed in the

[[Page 828]]

Memorandum of Agreement, the Memorandum of Agreement may be amended 
through the procedures set forth in this part. The State/EPA Agreement 
may not override the Memorandum of Agreement.

(The information collection requirements in paragraph (c) of this 
section have been approved by the Office of Management and Budget under 
control number 2040-0128)

[54 FR 18786, May 2, 1989, as amended at 58 FR 67984, Dec. 22, 1993; 63 
FR 45124, Aug. 24, 1998]



Sec.  501.15  Requirements for permitting.

    (a) General requirements. All State programs under this part must 
have legal authority to implement each of the following provisions and 
must be administered in conformance with each, except that States are 
not precluded from omitting or modifying any provisions to impose more 
stringent requirements:
    (1) Confidentiality of information. Claims of confidentiality will 
be denied for the following information:
    (i) The name and address of any permit applicant or permittee;
    (ii) Permit applications, permits, and sewage sludge data. This 
includes information submitted on the permit application forms 
themselves and any attachments used to supply information required by 
the forms.
    (2) Duration of permits. (i) NPDES permits issued to treatment works 
treating domestic sewage pursuant to section 405(f) of the CWA will be 
effective for a fixed term not to exceed five years.
    (ii) Non-NPDES Permits issued to treatment works treating domestic 
sewage pursuant to section 405(f) of the CWA will be effective for a 
fixed term not to exceed ten years.
    (3) Schedules of compliance--(i) General. The permit may, when 
appropriate, specify a schedule of compliance leading to compliance with 
the CWA and the requirements of this part. Any schedules of compliance 
under this section must require compliance as soon as possible, but not 
later than any applicable statutory deadline under the CWA.
    (ii) Interim dates. If a permit establishes a schedule of compliance 
which exceeds one year from the date of permit issuance, the schedule 
must set forth interim requirements and the date for their achievement, 
as appropriate.
    (iii) Reporting. The permit must be written to require that no later 
than 14 days following each interim date and the final date of 
compliance, the permittee must notify the Director in writing of its 
compliance or noncompliance with the interim or final requirements, or 
submit progress reports if paragraph (a)(3)(ii) of this section is 
applicable.
    (4) Information requirements: All treatment works treating domestic 
sewage shall submit to the Director within the time frames established 
in paragraph (d)(1)(ii) of this section the information listed in 
paragraphs (a)(4)(i) through (xii) of this section. The Director of an 
approved state program that chooses to receive electronic documents must 
satisfy the requirements of 40 CFR part 3--(Electronic reporting).
    (b) Conditions applicable to all permits. In addition to permit 
conditions which must be developed on a case-by-case basis in order to 
meet applicable requirements of 40 CFR part 503, paragraphs (a)(1) 
through (a)(3) of this section, and permit conditions developed on a 
case-by-case basis using best professional judgment to protect public 
health and the environment from the adverse effects of toxic pollutants 
in sewage sludge, all permits must contain the following permit 
conditions (or comparable conditions as provided for in the Memorandum 
of Agreement):
    (1) Duty to comply. The permittee must comply with all conditions of 
this permit. Any permit noncompliance constitutes a violation of the 
Clean Water Act and is grounds for enforcement action; for permit 
termination, revocation and reissuance, or modification; or denial of a 
permit renewal application.
    (2) Compliance with sludge standards. The permittee shall comply 
with standards for sewage sludge use or disposal established under 
section 405(d) of the CWA (40 CFR part 503) within the time provided in 
the regulations that establish such standards, even if this permit has 
not yet been modified to incorporate the standards.

[[Page 829]]

    (3) CWA penalties. Section 309 of the Clean Water Act (CWA) sets out 
penalties applicable to persons who violate the Act's requirements. For 
example, section 309(d) provides that any person who violates a permit 
condition implementing sections 301, 302, 306, 307, 308, 318, or 405 of 
the Clean Water Act is subject to a civil penalty not to exceed $25,000 
per day for each violation. Such violations also may be subject to 
administrative penalties assessed by the Administrator pursuant to 
section 309(g) of the CWA. Any person who negligently violates permit 
conditions implementing sections 301, 302, 306, 307, 308, or 405 of the 
Clean Water Act is subject to a fine not less than $2,500 nor more than 
$25,000 per day of violation or by imprisonment for not more than 1 
year, or both. Any person who knowingly violates a permit condition 
implementing sections 301, 302, 304, 307, 308, or 405 shall be punished 
by a fine not less than $5000 nor more than $50,000 per day of 
violation, or by imprisonment for not more than 3 years or both.
    (4) Need to halt or reduce activity not a defense. It shall not be a 
defense for a permittee in an enforcement action that it would have been 
necessary to halt or reduce the permitted activity in order to maintain 
compliance with the conditions of this permit.
    (5) Duty to mitigate. The permittee shall take all reasonable steps 
to minimize or prevent sludge use or disposal in violation of this 
permit which has a reasonable likelihood of adversely affecting human 
health or the environment.
    (6) Proper operation and maintenance. The permittee shall at all 
times properly operate and maintain all facilities and systems of 
treatment and control (and related appurtenances) which are installed or 
used by the permittee to achieve compliance with the conditions of this 
permit. Proper operation and maintenance also includes adequate 
laboratory controls and appropriate quality assurance procedures. This 
provision requires the operation of back-up or auxiliary facilities or 
similar systems which are installed by a permittee only when the 
operation is necessary to achieve compliance with the conditions of the 
permit.
    (7) Permit actions. This permit may be modified, revoked and 
reissued, or terminated for cause. The filing of a request by the 
permittee for a permit modification, revocation and reissuance, or 
termination, or a notification of planned changes or anticipated 
noncompliance does not stay any permit condition.
    (8) Duty to provide information. The permittee shall furnish to the 
Director, within a reasonable time, any information which the Director 
may request to determine whether cause exists for modifying, revoking 
and reissuing, or terminating this permit or to determine compliance 
with this permit. The permittee shall also furnish to the Director, upon 
request, copies of records required to be kept by this permit.

    (iii) Inspect at reasonable times any facilities, equipment 
(including monitoring and control equipment), practices, or operations 
regulated or required under this permit; and
    (iv) Sample or monitor at reasonable times, for the purposes of 
assuring permit compliance or as otherwise authorized by the Clean Water 
Act, any substances, parameters or practices at any location.
    (10) Monitoring and records. (i) The permittee must monitor and 
report monitoring results as specified elsewhere in this permit with a 
frequency dependent on the nature and effect of its sludge use or 
disposal practices. At a minimum, this will be as required by 40 CFR 
part 503.
    (ii) Samples and measurements taken for the purpose of monitoring 
shall be representative of the monitored activity. The permittee shall 
retain records of all monitoring information, copies

[[Page 830]]

of all reports required by this permit, and records of all data used to 
complete the application for this permit, for a period of at least five 
years from the date of the sample, measurement, report or application, 
or longer as required by 40 CFR part 503. This period may be extended by 
request of the Director at any time.
    (iii) Records of monitoring information shall include:
    (A) The date, exact place, and time of sampling or measurements;
    (B) The individual(s) who perfored the sampling or measurements;
    (C) The date(s) analyses were performed;

been specified in this permit.
    (v) The Clean Water Act provides that any person who knowingly 
falsifies, tampers with, or renders inaccurate any monitoring device or 
method required to be maintained under this permit shall, upon 
conviction, be punished for the first conviction by a fine of not more 
than $10,000 or by imprisonment for not more than 2 years per violation, 
or by both. Subsequent convictions for the same offense are punishable 
by a fine of not more than $20,000 per day of violation, or imprisonment 
of not more than 4 years, or both.
    (11) Signatory requirements. (i) All applications, reports, or 
information submitted to the Director shall be signed and certified 
according to the provisions of 40 CFR 122.22.
    (ii) The CWA provides that any person who knowingly makes any false 
statement, representation, or certification in any record or other 
document submitted or required to be maintained under this permit shall, 
upon conviction, be punished for the first conviction by a fine of not 
more than $10,000 per violation, or by imprisonment for not more than 2 
years per violation, or by both. Subsequent convictions shall be 
punishable by a fine of not more than $20,000 per day of violation or by 
imprisonment of not more than 4 years, or by both.
    (12) Notice requirements--(i) Planned changes. The permittee shall 
give notice to the Director as soon as possible of any planned physical 
alterations or additions to the permitted facility, or significant 
changes planned in the permittee's sludge disposal practice, where such 
alterations, additions, or changes may justify the application of permit 
conditions that are different from or absent in the existing permit, 
including notification of additional disposal sites not reported during 
the permit application process or not reported pursuant to an approved 
land application plan.
    (ii) Anticipated noncompliance. The permittee shall give advance 
notice to the Director of any planned changes in the permitted facility 
or activity which may result in noncompliance with permit requirements.
    (iii) Transfers. This permit is not transferable to any person 
except after notice to the Director. The Director may require 
modification or revocation and reissuance of the permit to change the 
name of the permittee and incorporate such other requirements as may be 
necessary under the CWA.
    (iv) Other noncompliance reporting. The permittee shall report all 
instances of noncompliance. Reports of noncompliance shall be submitted 
with the permittee's next self monitoring report or earlier. if 
requested by the Director or if required by an applicable standard for 
sewage sludge use or disposal or condition of this permit.
    (v) Other information. Where the permittee becomes aware that it 
failed to submit any relevant facts in a permit application, or 
submitted incorrect information in a permit application or in any report 
to the Director, it shall promptly submit such facts or information.
    (13) Reopener. If a standard for sewage sludge use or disposal 
applicable to permittee's use or disposal methods is promulgated under 
section 405(d) of the CWA before the expiration of this permit, and that 
standard is more stringent than the sludge pollutant limits or 
acceptable management practices authorized in this permit, or controls a

[[Page 831]]

pollutant or practice not limited in this permit, this permit may be 
promptly modified or revoked and reissued to conform to the standard for 
sludge use or disposal promulgated under section 405(d) of the CWA.
    (14) Duty to reapply. If the permittee wishes to continue an 
activity regulated by the this permit after the expiration date of this 
permit, the permittee must apply for a new permit.
    (15) Indian Tribes can satisfy the criminal enforcement authority 
requirements of this section under Sec.  501.25.
    (c) Permit actions. All State programs under this part shall have 
the legal authority to implement the following provisions as a minimum 
and must be administered in conformance with each.
    (1) Transfer of permits--(i) Transfers by modification. Except as 
provided in paragraph (ii) of this section, a permit may be transferred 
by the permittee to a new owner or operator only if the permit has been 
modified or revoked and reissued to identify the new permittee and 
incorporate such other requirements as may be necessary to assure 
compliance with the CWA.
    (ii) Automatic transfers. As an alternative to transfers under 
paragraph (c)(1)(i) of this section, the State Director may authorize 
automatic transfer of any sludge permit to a new permittee if:
    (A) The current permittee notifies the Director at least 30 days in 
advance of the proposed transfer date in paragraph (c)(1)(ii)(B) of this 
section;
    (B) The notice includes a written agreement between the existing and 
new permittees containing a specific date for transfer of permit 
responsibility, coverage, and liability between them; and
    (C) The Director does not notify the existing permittee and the 
proposed new permittee of his or her intent to modify or revoke and 
reissue the permit. If this notice is not received, the transfer is 
effective on the date specified in the agreement mentioned in paragraph 
(c)(ii)(B) of this section.
    (2) Modification or revocation and reissuance of permits. (i) When 
the Director receives any information (for example, where the Director 
inspects the facility, receives information submitted by the permittee 
as required in the permit, receives a request for modification or 
revocation and reissuance under Sec.  501.15(d)(2)(i), or conducts a 
review of the permit file), he or she may determine whether or not one 
or more of the causes listed in paragraphs (c)(2) (ii) and (iii) of this 
section for modification or revocation and reissuance or both exist. If 
cause exists, the Director may modify or revoke and reissue the permit 
and may request an updated application if necessary. When a permit is 
modified, only the conditions subject to a modification are reopened. If 
a permit is revoked and reissued, the entire permit is reopened and 
subject to revision and the permit is reissued for a new term. A draft 
permit must be prepared and other procedures in Sec.  501.15(d) 
followed. If cause does not exist under this section, the Director shall 
not modify or revoke and reissue the permit.
    (ii) Causes for modification. The following are causes for 
modification but not revocation and reissuance of permits except when 
the permittee requests or agrees.
    (A) Alterations. There are material and substantial alterations or 
additions to the permitted facility or activity which occurred after 
permit issuance which justify the application of permit conditions that 
are different from or absent in the existing permit.
    (B) Information. The Director has received new information. Permits 
may be modified during their terms for this cause only if the 
information was not available at the time of permit issuance (other than 
revised regulations, guidance, or test methods) and would have justified 
the application of different permit conditions at the time of issuance.
    (C) New regulations. New regulations have been promulgated under 
section 405(d) of the CWA, or the standards or regulations on which the 
permit was based have been changed by promulgation of amended standards 
or regulations or by judicial decision after the permit was issued.
    (D) Compliance schedules. The Director determines good cause exists 
for modification of a compliance schedule, such as an Act of God, 
strike, flood, or

[[Page 832]]

materials shortage or other events over which the permittee has little 
or no control and for which there is no reasonable available remedy. 
However, in no case may a compliance schedule be modified to extend 
beyond an applicable CWA statutory deadline.
    (E) Land application plans. When required by a permit condition to 
incorporate a land application plan for beneficial reuse of sewage 
sludge, to revise an existing land application plan, or to add a land 
application plan.
    (iii) The following are causes to modify or alternatively, revoke 
and reissue, a permit.
    (A) Cause exists for termination under Sec.  501.15(c)(3) and the 
Director determines that modification or revocation and reissuance is 
appropriate.
    (B) The Director has received notification (as required in the 
permit, see Sec.  501.15(b)(12)(iii)) of a proposed transfer of the 
permit.
    (3) Termination of permits. The following are causes for terminating 
a permit during its term, or for denying a permit renewal application:
    (i) Noncompliance by the permittee with any condition of the permit;
    (ii) The permittee's failure in the application or during the permit 
issuance process to disclose fully all relevant facts, or the 
permittee's misrepresentation of any relevant facts at any time;
    (iii) A determination that the permitted activity endangers human 
health or the environment and can only be regulated to acceptable levels 
by permit modification or termination; or
    (iv) A change in any condition that requires either a temporary or a 
permanent reduction or elimination of any activity controlled by the 
permit.
    (d) Permit procedures. All State programs approved under this part 
must have the legal authority to implement, and be administered in 
accordance with, each of following provisions, unless the Regional 
Administrator determines that the State program includes comparable or 
more stringent provisions.
    (1) Application for a permit. (i) Any TWTDS whose sewage sludge use 
or disposal method is covered by part 503 and covered under the State 
program, and who does not have an effective sewage sludge permit, must 
complete, sign, and submit to the Director an application for a permit 
within the following time frames.
    (A) TWTDS with a currently effective NPDES permit must submit the 
required application information when the next application for NPDES 
permit renewal is due.
    (B) The required application information is listed in 40 CFR 
122.21(q).
    (C) Other existing TWTDS not addressed under paragraph (d)(1)(i)(A) 
of this section must submit the information listed in paragraphs 
(d)(1)(i)(C)(1) through (d)(I)(i)(C)(5) of this section, to the Director 
within one year after publication of a standard applicable to their 
sewage sludge use or disposal practices. The Director will determine 
when such a TWTDS must submit a full permit application.
    (1) Name, mailing address and location of the TWTDS;
    (2) The operator's name, address, telephone number, ownership 
status, and status as Federal, State, private, public or other entity;
    (3) A description of the sewage sludge use or disposal practices. 
Unless the sewage sludge meets the ceiling concentrations in 40 CFR 
503.13(b)(1), the pollutant concentrations in 40 CFR 503.13(b)(3), the 
Class A pathogen requirements in 40 CFR 503.32(a), and one of the vector 
attraction reduction requirements in 40 CFR 503.33(b)(1) through (b)(8), 
the description must include the name and address of any facility where 
sewage sludge is sent for treatment or disposal, and the location of any 
land application sites;
    (4) Annual amount of sewage sludge generated, treated, used or 
disposed (dry weight basis); and
    (5) The most recent data the TWTDS may have on the quality of the 
sewage sludge.
    (D) Notwithstanding paragraph (d)(1)(i)(A) or (d)(1)(i)(B) of this 
section, the Director may require permit applications from any TWTDS at 
any time if the Director determines that a permit is necessary to 
protect public health and the environment from any potential adverse 
effects that may occur from toxic pollutants in sewage sludge.

[[Page 833]]

    (E) Any TWTDS that commences operations after promulgation of an 
applicable standard for sewage sludge use or disposal must submit an 
application to the Director at least 180 days prior to the date proposed 
for commencing operations.
    (ii) All TWTDS with a currently effective sewage sludge permit must 
submit a new application at least 180 days before the expiration date of 
their existing permit.
    (iii) The Director will not begin the processing of a permit until 
the applicant has fully complied with the application requirements for 
that permit.
    (2) Modification, revocation and reissuance, or termination of 
permits. (i) Permits may be modified, revoked and reissued, or 
terminated either at the request of any interested person (including the 
permittee) or upon the Director's initiative. However, permits may only 
be modified, revoked and reissued, or terminated for the reasons 
specified in Sec.  501.15(c). All requests shall be in writing and shall 
contain factors or reasons supporting the request.
    (ii) If the Director tentatively decides to modify or revoke and 
reissue a permit he or she shall prepare a draft permit incorporating 
the proposed changes. The Director may request additional information 
and, in the case of a modified permit, may require the submission of an 
updated application. In the case of a revoked and reissued permit, the 
Director shall require the submission of a new application. If the 
Director tentatively decides to terminate a permit he or she shall 
prepare a Notice of Intent to Terminate and follow the public notice and 
comment procedures outlined in Section 501.15(d)(6).
    (3) Draft permits. Once an application is complete, the Director 
shall tentatively decide whether to prepare a draft permit or to deny 
the application. If the Director decides to prepare a draft permit, he 
or she shall prepare a draft permit that contains the necessary 
conditions to implement this part, 40 CFR part 503, and section 405 of 
the CWA.
    (4) Fact sheets. A fact sheet must be prepared for every draft 
permit which the Director finds is the subject of widespread public 
interest or raises major issues. The fact sheet will briefly set forth 
the principal facts and the significant factual, legal, methodological 
and policy questions considered in preparing the draft permit. The 
Director will send this fact sheet to the applicant and, on request, to 
any other person.
    (5) Public notice of permit actions and public comment period. (i) 
The Director must give public notice that the following actions have 
occurred:
    (A) A draft permit has been prepared. At least 30 days must be 
allowed for public comment on the draft permit unless the Director has 
previously provided for public comment, for example after receipt of the 
permit application.
    (B) A meeting or hearing has been scheduled.
    (ii) Methods. Public notice of activities described in paragraph 
(d)(5)(i) of this section must be given in the area affected by these 
activities by any method reasonably calculated to give actual notice of 
the action in question to any person affected or requesting notice of 
the action. Public notice may include publication of a notice in a daily 
or weekly newspaper within the area affected by the facility or 
activity, press releases, or any other forum or medium to elicit public 
participation.
    (iii) Contents--(A) All public notices. All public notices issued 
under this part must contain the following minimum information:
    (1) Name and address of the office processing the permit action for 
which notice is being given;
    (2) Name and address of the permittee or permit applicant and, if 
different, of the facility or activity regulated by the permit;
    (3) A brief description of the activity described in the permit

other procedures by which the public may participate in the final permit 
decision; and
    (6) Any additional information considered necessary or proper.
    (B) Public notices for meetings or hearings. In addition to the 
general public notice described in paragraph (d)(5)(iii)(A) of this 
section, the public notice of a meeting or hearing must contain the 
following information:

    (2) A brief description of the nature and purpose of the meeting or 
hearing, including the applicable rules and procedures.
    (6) Public comments and requests for public meetings or hearings. 
During the public comment period, any interested person may submit 
written comments on the draft permit and may request a public meeting or 
hearing, if no meeting or hearing has already been scheduled. A request 
for a public meeting or hearing must be in writing and must state the 
nature of the issues proposed to be raised in the meeting or hearing. 
All comments will be considered in making the final decision and must be 
answered as provided in paragraph (d)(8) of this section.

meeting or hearing whenever he or she finds, on the basis of requests, a 
significant degree of public interest in a draft permit. The Director 
may also hold a public meeting or hearing at his or her discretion, 
(e.g. where such a hearing might clarify one or more issues involved in 
the permit decision).
    (8) Response to comments. At the time a final permit is issued, the 
Director will issue a response to comments. The response to comments 
must be available to the public, and must:
    (i) Specify which provisions, if any, of the draft permit have been 
changed in the final permit decision, and the reasons for the change; 
and
    (ii) Briefly describe and respond to all significant comments on the 
draft permit raised during the public comment period or during any

the corresponding Federal provisions:
    (1) Continuation of expiring permits (40 CFR 122.6);
    (2) General permits (40 CFR 122.28);
    (3) Minor modifications of permits (40 CFR 122.63); and
    (4) Effect of permit: affirmative defense (40 CFR 122.5(b)).
    (f) Conflict of interest. Except as provided in paragraph (f)(2), 
State sludge management programs shall ensure that any board or body 
which approves all or portions of permits shall not include as a member 
any person who receives, or has during the previous two years received,

    (2) The Administrator may waive the requirements of this paragraph 
if the

[[Page 835]]

board or body which approves all or portions of permits is subject to, 
and certifies that it meets, a conflict-of-interest standard imposed as 
part of another EPA-approved State permitting program or an equivalent 
standard.

Sec.  501.16  Requirements for compliance evaluation programs.

    State sludge management programs shall have requirements and 
procedures for compliance monitoring and evaluation as set forth in 
Sec.  123.26.



Sec.  501.17  Requirements for enforcement authority.

    (a) Any State agency administering a program shall have available 
the following remedies for violations of State program requirements:
    (1) To restrain immediately and effectively any person by order or 
by suit in State court from engaging in any unauthorized activity which 
is endangering or causing damage to public health or the environment;
    Note: This paragraph ((a)(1)) requires that States have a mechanism 
(e.g., an administrative cease and desist order or the ability to seek a 
temporary restraining order) to stop any unauthorized activity 
endangering public health or the environment.
    (2) To sue in courts of competent jurisdiction to enjoin any 
threatened or continuing violation of any program requirement, including 
permit conditions, without the necessity of a prior revocation of the 
permit; and
    (3) To assess or sue to recover in court civil penalties and to seek 
criminal remedies, including fines, as follows:
    (i) Civil penalties will be recoverable for the violation of any 
permit condition; any applicable standard or limitation; any filing 
requirement; any duty to allow or carry out inspection, entry or 
monitoring activities; or any regulation or orders issued by the State 
Program Director. The State must at a minimum, have the authority to 
assess penalties of up to $5,000 a day for each violation.
    (ii) Criminal fines will be recoverable against any person who 
willfully or negligently violates any applicable standards or 
limitations; any permit condition; or any filing requirement. The State 
must at a minimum, have the authority to assess fines of up to $10,000 a 
day for each violation. States which provide the criminal remedies based 
on ``criminal negligence,'' ``gross negligence'' or strict liability 
satisfy the requirement of this paragraph (a)(3)(ii) of this section.
    (iii) Criminal fines will be recoverable against any person who 
knowingly makes any false statement, representation or certification in 
any program form, or in any notice or report required by a permit or 
State Program Director, or who knowingly renders inaccurate any 
monitoring device or method required to be maintained by the State 
Program Director. The State must at a minimum, have the authority to 
assess fines of up to $5,000 for each instance of violation.
    (b)(1) The civil penalty or criminal fine will be assessable for 
each instance of violation and, if the violation is continuous, will be 
assessable up to the maximum amount for each day of violation.
    (2) The burden of proof and degree of knowledge or intent required 
under State law for establishing violations under paragraph (a)(3) of 
this section shall be no greater than the burden of proof or degree of 
knowledge or intent EPA must provide when it brings an action under the 
appropriate Act.
    Note: For example, this requirement is not met if State law includes 
mental state as an element of proof for civil violations.
    (c) A civil penalty assessed, sought, or agreed upon by the State 
Program Director under paragraph (a)(3) of this section shall be 
appropriate to the violation.
    (d) Any State administering a program shall provide for public 
participation in the State enforcement process by providing either:
    (1) Authority which allows intervention as of right in any civil or 
administrative action to obtain remedies specified in paragraphs (a)(1), 
(2) or (3) of this section by any citizen having an interest which is or 
may be adversely affected; or
    (2) Assurance that the State agency or enforcement authority will:

[[Page 836]]

    (i) Investigate and provide responses to all citizen complaints 
submitted pursuant to the procedures specified in 40 CFR 123.26(b)(4);
    (ii) Not oppose intervention by any citizen in any civil or 
administrative proceeding when permissive intervention may be authorized 
by statute, rule, or regulation; and
    (iii) Publish notice of and provide at least 30 days for public 
comment on any proposed settlement of a State enforcement action.
    (e) Indian Tribes that cannot satisfy the criminal enforcement 
authority requirements of this section may still be approved under this 
part if they meet the requirements established in Sec.  501.25.

Sec.  501.18  Prohibition.

    State permit programs shall provide that no permit shall be issued 
when the Regional Administrator has objected in writing under 40 CFR 
123.44.



Sec.  501.19  Sharing of information.

    State sludge management programs shall comply with the requirements 
of 40 CFR 123.41.



Sec.  501.20  Receipt and use of federal information.

    State sludge management programs shall comply with 40 CFR 123.42.



Sec.  501.21  Program reporting to EPA.

  Sec. Appendix A to Part 503--Procedure To Determine the Annual Whole 
               Sludge Application Rate for a Sewage Sludge

    Section 503.13(a)(4)(ii) requires that the product of the 
concentration for each pollutant listed in Table 4 of Sec.  503.13 in 
sewage sludge sold or given away in a bag or other container for 
application to the land and the annual whole sludge application rate 
(AWSAR) for the sewage sludge not cause the annual pollutant loading 
rate for the pollutant in Table 4 of Sec.  503.13 to be exceeded. This 
appendix contains the procedure used to determine the AWSAR for a sewage 
sludge that does not cause the annual pollutant loading rates in Table 4 
of Sec.  503.13 to be exceeded.
    The relationship between the annual pollutant loading rate (APLR) 
for a pollutant and the annual whole sludge application rate (AWSAR) for 
1a sewage sludge is shown in equation (1).
[GRAPHIC] [TIFF OMITTED] TC15NO91.200

Where:

APLR = Annual pollutant loading rate in kilograms per hectare per 365 
          day period.
C = Pollutant concentration in milligrams, per kilogram of total solids 
          (dry weight basis).
AWSAR = Annual whole sludge application rate in metric tons per hectare 
          per 365 day period (dry weight basis).
0.001 = A conversion factor.

    To determine the AWSAR, equation (1) is rearranged into equation 
(2):
[GRAPHIC] [TIFF OMITTED] TC15NO91.201

    The procedure used to determine the AWSAR for a sewage sludge is 
presented below.

                               Procedure:

    1. Analyze a sample of the sewage sludge to determine the 
concentration for each of the pollutants listed in Table 4 of Sec.  
503.13 in the sewage sludge.

[[Page 871]]

    2. Using the pollutant concentrations from Step 1 and the APLRs from 
Table 4 of Sec.  503.13, calculate an AWSAR for each pollutant using 
equation (2) above.
    3. The AWSAR for the sewage sludge is the lowest AWSAR calculated in 
Step 2.



        Sec. Appendix B to Part 503--Pathogen Treatment Processes

          A. Processes To Significantly Reduce Pathogens (PSRP)

    1. Aerobic digestion--Sewage sludge is agitated with air or oxygen 
to maintain aerobic conditions for a specific mean cell residence time 
at a specific temperature. Values for the mean cell residence time and 
temperature shall be between 40 days at 20 degrees Celsius and 60 days 
at 15 degrees Celsius.
    2. Air drying--Sewage sludge is dried on sand beds or on paved or 
unpaved basins. The sewage sludge dries for a minimum of three months. 
During two of the three months, the ambient average daily temperature is 
above zero degrees Celsius.
    3. Anaerobic digestion--Sewage sludge is treated in the absence of 
air for a specific mean cell residence time at a specific temperature. 
Values for the mean cell residence time and temperature shall be between 
15 days at 35 to 55 degrees Celsius and 60 days at 20 degrees Celsius.
    4. Composting--Using either the within-vessel, static aerated pile, 
or windrow composting methods, the temperature of the sewage sludge is 
raised to 40 degrees Celsius or higher and remains at 40 degrees Celsius 
or higher for five days. For four hours during the five days, the 
temperature in the compost pile exceeds 55 degrees Celsius.
    5. Lime stabilization--Sufficient lime is added to the sewage sludge 
to raise the pH of the sewage sludge to 12 after two hours of contact.
    B. Processes to Further Reduce Pathogens (PFRP)
    1. Composting--Using either the within-vessel composting method or 
the static aerated pile composting method, the temperature of the sewage 
sludge is maintained at 55 degrees Celsius or higher for three days.
    Using the windrow composting method, the temperature of the sewage 
sludge is maintained at 55 degrees or higher for 15 days or longer. 
During the period when the compost is maintained at 55 degrees or 
higher, there shall be a minimum of five turnings of the windrow.
    2. Heat drying--Sewage sludge is dried by direct or indirect contact 
with hot gases to reduce the moisture content of the sewage sludge to 10 
percent or lower. Either the temperature of the sewage sludge particles 
exceeds 80 degrees Celsius or the wet bulb temperature of the gas in 
contact with the sewage sludge as the sewage sludge leaves the dryer 
exceeds 80 degrees Celsius.
    3. Heat treatment--Liquid sewage sludge is heated to a temperature 
of 180 degrees Celsius or higher for 30 minutes.
    4. Thermophilic aerobic digestion--Liquid sewage sludge is agitated 
with air or oxygen to maintain aerobic conditions and the mean cell 
residence time of the sewage sludge is 10 days at 55 to 60 degrees 
Celsius.
    5. Beta ray irradiation--Sewage sludge is irradiated with beta rays 
from an accelerator at dosages of at least 1.0 megarad at room 
temperature (ca. 20 degrees Celsius).
    (6) Gamma ray irradiation--Sewage sludge is irradiated with gamma 
rays from certain isotopes, such as \60\ Cobalt and \137\ Cesium, at 
dosages of at least 1.0 megarad at room temperature (ca. 20 
[deg]Celsius).
    7. Pasteurization--The temperature of the sewage sludge is 
maintained at 70 degrees Celsius or higher for 30 minutes or longer.

with fleet average CO2 standards in Sec.  86.1818 of this 
chapter.
    (d) The model year of initial applicability for sections in this 
part is indicated by the section number. The two digits following the 
hyphen designate the first model year for which a section is applicable. 
An individual section continues to apply for later model years until it 
is replaced by a different section that applies starting in a later 
model year. Sections that have no two-digit suffix apply for all 2008 
and later model year vehicles, except as noted in those sections. If a 
section has a two-digit suffix but the regulation references that 
section without including the two-digit suffix, this refers to the 
section applicable for the appropriate model year. This also applies for 
references to part 86 of this chapter. As an example, Sec.  600.113-08 
applies to the 2008 and subsequent model years until Sec.  600.113-12 is 
applicable beginning with the 2012 model year. Section 600.111-08 would 
then apply only for 2008 through 2011 model year vehicles.
    (e) The term ``you'' in this part refers to manufacturers subject to 
the requirements of this part.
    (f) Unless we specify otherwise, send all reports and requests for 
approval to the Designated Compliance Officer (see Sec.  600.002).

    Usable fuel storage capacity means the amount of fuel that is 
available to a vehicle starting from a complete refueling event until 
the vehicle stops (or until driveability deteriorates to the point that 
further driving is unlikely or impractical). For liquid fuels, the 
usable fuel storage capacity represents the difference between the total 
fuel volume after a complete refueling event and the fuel volume that 
remains in the fuel tank after the vehicle runs out of fuel. For other 
fuels, use good engineering judgment to determine the full and empty 
conditions consistent with typical consumer behavior. For example, for 
natural gas vehicles, the full condition would be the point at which a 
typical operator would stop refueling based on the increasing system 
pressures, which are determined by temperature effects related to the 
refueling process; this does not necessarily represent the maximum 
amount of fuel the tank can hold under equilibrium conditions. The empty 
condition would be the point at which fuel pressure drops enough that 
the engine is unable to maintain stable air-fuel ratios for acceptable 
continued operation.
    Van means any light truck having an integral enclosure fully 
enclosing the driver compartment and load carrying compartment. The 
distance from the leading edge of the windshield to the foremost body

for it, the person authorizing it, and the names of supervisory 
personnel responsible for the conduct of the maintenance or service. A 
copy of the maintenance information to be submitted under Sec.  600.006 
fulfills the requirements of this paragraph (a)(2)(v).
    (vi) A brief description of any significant events affecting the 
vehicle during any of the period covered by the history not described in 
an entry under one of the previous headings including such extraordinary 
events as vehicle accidents or driver speeding citations or warnings.
    (3) Keeping records. The manufacturer shall retain all records 
required under this part for five years after the end of the model year 
to which they relate. Records may be retained as hard copy or some 
alternative storage medium, provided that in every case all the 
information contained in hard copy shall be retained.
    (b)(1) Any manufacturer who has supplied fuel economy data to meet 
the requirements of this part shall admit any EPA Enforcement Officer 
during operating hours upon presentation of credentials at any of the 
following:
    (i) Any facility where any fuel economy tests from which data are 
submitted or any procedures or activities connected with these tests are 
performed.
    (ii) Any facility where any new motor vehicle which is being, was, 
or is to be tested is present.
    (iii) Any facility where any construction process used in the 
modification or buildup of a vehicle into a fuel economy data vehicle is 
taking place or has taken place.
    (iv) Any facility where any record or other document relating to any 
of the above is located.
    (2) Upon admission to any facility referred to in paragraph (b)(1) 
of this section, the manufacturer shall allow any EPA Enforcement 
Officer:

whether or not the manufacturer controls the facility.
    (4) The duty to admit any EPA Enforcement Officer shall be 
applicable whether or not the manufacturer owns or controls the facility 
in question and is applicable to both domestic and foreign manufacturers 
and facilities. An EPA Enforcement Officer will not attempt to make any 
inspections which the officer has been informed are in contravention of 
any law. However, if local law makes it impossible for the EPA 
Enforcement Officer to verify or to ensure the accuracy of data 
generated at a facility such that no informed judgment can properly be 
made as to the accuracy or reliability of data generated by or obtained 
for the facility, then a vehicle or data from that vehicle shall not be 
accepted for use in subpart C or F of this part (unless the 
Administrator is otherwise convinced of the accuracy and reliability of 
such data).

    (v) If calibrations for components specified in paragraph (b)(2) 
(iii) or (iv) of this section were submitted previously as part of the 
description of another vehicle or configuration, the original submittal 
may be referenced.
    (c) The manufacturer shall submit the following fuel economy data:
    (1) For vehicles tested to meet the requirements of part 86 of this 
chapter (other than those chosen in accordance with the provisions 
related to durability demonstration in Sec.  86.1829 of this chapter or 
in-use verification testing in Sec.  86.1845 of this chapter), the FTP, 
highway, US06, SC03 and cold temperature FTP fuel economy results, as 
applicable, from all tests on that vehicle, and the test results 
adjusted in accordance with paragraph (g) of this section.
    (2) For each fuel economy data vehicle, all individual test results 
(excluding results of invalid and zero mile tests) and these test 
results adjusted in accordance with paragraph (g) of this section.
    (3) For diesel vehicles tested to meet the requirements of part 86 
of this chapter, data from a cold temperature FTP, performed in 
accordance with Sec.  600.111-08(e), using the fuel specified in Sec.  
600.107-08(c).
    (4) For all vehicles tested in paragraph (c)(1) through (3) of this 
section, the individual fuel economy results measured on a per-phase 
basis, that is, the individual phase results for all sample phases of 
the FTP, cold temperature FTP and US06 tests.
    (5) Starting with the 2012 model year, the data submitted according 
to paragraphs (c)(1) through (4) of this section shall include total HC, 
CO, CO2, and, where applicable for alternative fuel vehicles, 
CH3OH, C2H5OH, 
C2H4O, HCHO, NMHC and CH4. 
Manufacturers incorporating N2O and CH4 emissions 
in their fleet average carbon-related exhaust emissions as allowed under 
Sec.  86.1818 of this chapter shall also submit N2O and 
CH4 emission data where applicable. The fuel economy, carbon-
related exhaust emissions, and CO2 emission test results 
shall be adjusted in accordance with paragraph (g) of this section.
    (d) The manufacturer shall submit an indication of the intended 
purpose of the data (e.g., data required by the general labeling program 
or voluntarily submitted for specific labeling).
    (e) In lieu of submitting actual data from a test vehicle, a 
manufacturer may provide fuel economy, CO2 emissions, and 
carbon-related exhaust emission values derived from a previously tested 
vehicle, where the fuel economy, CO2 emissions, and carbon-
related exhaust emissions are expected to be equivalent (or less fuel-
efficient and with higher CO2 emissions and carbon-related 
exhaust emissions). Additionally, in lieu of submitting actual data from 
a test vehicle, a manufacturer may provide fuel economy, CO2 
emissions, and carbon-related exhaust emission values derived from an 
analytical

[[Page 883]]

expression, e.g., regression analysis. In order for fuel economy, 
CO2 emissions, and carbon-related exhaust emission values 
derived from analytical methods to be accepted, the expression (form and 
coefficients) must have been approved by the Administrator.
    (f) If, in conducting tests required or authorized by this part, the 
manufacturer utilizes procedures, equipment, or facilities not described 
in the Application for Certification required in Sec.  86.1844-01 of 
this chapter, the manufacturer shall submit to the Administrator a 
description of such procedures, equipment, and facilities.
    (g)(1) The manufacturer shall adjust all test data used for fuel 
economy label calculations in subpart D and average fuel economy 
calculations in subpart F for the classes of automobiles within the 
categories identified in paragraphs of Sec.  600.510(a)(1) through (4). 
The test data shall be adjusted in accordance with paragraph (g)(3) or 
(4) of this section as applicable.
    (2) [Reserved]
    (3)(i) The manufacturer shall adjust all fuel economy test data 
generated by vehicles with engine-drive system combinations with more 
than 6,200 miles by using the following equation:

FE4,000mi = FET[0.979 + 5.25 x 
10-6(mi)]-1

Where:

FE4,000mi = Fuel economy data adjusted to 4,000-mile test 
          point rounded to the nearest 0.1 mpg.
FET = Tested fuel economy value rounded to the nearest 0.1 
          mpg.
mi = System miles accumulated at the start of the test rounded to the 
          nearest whole mile.

    (ii)(A) The manufacturer shall adjust all carbon-related exhaust 
emission (CREE) and all CO2 test data generated by vehicles 
with engine-drive system combinations with more than 6,200 miles by 
using the following equation:

ADJ4,000mi = TEST[0.979 + 5.25 [middot] 10-6 
[middot] (mi)]

Where:

ADJ4,000mi = CREE or CO2 emission data adjusted to 
          4,000-mile test point.
TEST = Tested emissions value of CREE or CO2 in grams per 
          mile.
mi = System miles accumulated at the start of the test rounded to the 
          nearest whole mile.

    (B) Emissions test values and results used and determined in the 
calculations in this paragraph (g)(3)(ii) shall be rounded in accordance 
with Sec.  86.1837 of this chapter as applicable. CO2 and 
CREE values shall be rounded to the nearest gram per mile.
    (C) Note that the CREE test results are determined using the 
unadjusted CO2 value; i.e., CO2 is not adjusted 
twice when determining the 4,000 mile CREE value.
    (4) For vehicles with 6,200 miles or less accumulated, the 
manufacturer is not required to adjust the data.
    (5) The Administrator may specify a different adjustment calculation 
for electric vehicles, plug-in hybrid electric vehicles, and fuel cell 
vehicles to allow for properly characterizing the fuel economy and 
emissions of these vehicles.

Sec.  600.007  Vehicle acceptability.

    (a) All certification vehicles and other vehicles tested to meet the 
requirements of part 86 of this chapter (other than those chosen under 
the durability-demonstration provisions in Sec.  86.1829 of this 
chapter), are considered to have met the requirements of this section.
    (b) Any vehicle not meeting the provisions of paragraph (a) of this 
section must be judged acceptable by the Administrator under this 
section in order for the test results to be reviewed for use in subpart 
C or F of this part. The Administrator will judge the acceptability of a 
fuel economy data vehicle on the basis of the information supplied by 
the manufacturer under Sec.  600.006(b). The criteria to be met are:
    (1) A fuel economy data vehicle may have accumulated not more than 
10,000 miles. A vehicle will be considered to have met this requirement 
if the engine and drivetrain have accumulated 10,000 or fewer miles. The 
Administrator may specify a different maximum value for electric 
vehicles, plug-in hybrid electric vehicles, and fuel cell vehicles that 
allows for the necessary operation for properly evaluating and 
characterizing those vehicles under this part. The components installed 
for

[[Page 884]]

a fuel economy test are not required to be the ones with which the 
mileage was accumulated, e.g., axles, transmission types, and tire sizes 
may be changed. The Administrator will determine if vehicle/engine 
component changes are acceptable.
    (2) A vehicle may be tested in different vehicle configurations by 
change of vehicle components, as specified in paragraph (b)(1) of this 
section, or by testing in different inertia weight classes. Also, a 
single vehicle may be tested under different test conditions, i.e., test 
weight and/or road load horsepower, to generate fuel economy data 
representing various situations within a vehicle configuration. For 
purposes of this part, data generated by a single vehicle tested in 
various test conditions will be treated as if the data were generated by 
the testing of multiple vehicles.
    (3) The mileage on a fuel economy data vehicle must be, to the 
extent possible, accumulated according to Sec.  86.1831 of this chapter.
    (4) Each fuel economy data vehicle must meet the same exhaust 
emission standards as certification vehicles of the respective engine-
system combination during the test in which the city fuel economy test 
results are generated. This may be demonstrated using one of the 
following methods:
    (i) The deterioration factors established for the respective engine-
system combination per Sec.  86.1841 of this chapter as applicable will 
be used; or
    (ii) The fuel economy data vehicle will be equipped with aged 
emission control components according to the provisions of Sec.  86.1823 
of this chapter.
    (5) The calibration information submitted under Sec.  600.006(b) 
must be representative of the vehicle configuration for which the fuel 
economy, CO2 emissions, and carbon-related exhaust emissions 
data were submitted.
    (6) Any vehicle tested for fuel economy, CO2 emissions, 
or carbon-related exhaust emissions purposes must be representative of a 
vehicle which the manufacturer intends to produce under the provisions 
of a certificate of conformity.
    (7) For vehicles imported under Sec.  85.1509 or Sec.  
85.1511(b)(2), (b)(4), (c)(1), (c)(2) or (d) of this chapter (when 
applicable), only the following requirements must be met:
    (i) For vehicles imported under Sec.  85.1509 of this chapter, a 
highway fuel economy value must be generated contemporaneously with the 
emission tests used for purposes of demonstrating compliance with Sec.  
85.1509 of this chapter. No modifications or adjustments should be made 
to the vehicles between the highway fuel economy, FTP, US06, SC03 and 
Cold temperature FTP tests.
    (ii) For vehicles imported under Sec.  85.1509 or Sec.  
85.1511(b)(2), (b)(4), (c)(1), or (c)(2) of this chapter (when 
applicable) with over 10,000 miles, the equation in Sec.  600.006(g)(3) 
shall be used as though only 10,000 miles had been accumulated.
    (iii) Any required fuel economy testing must take place after any 
safety modifications are completed for each vehicle as required by 
regulations of the Department of Transportation.
    (iv) Every vehicle imported under Sec.  85.1509 or Sec.  
85.1511(b)(2), (b)(4), (c)(1), or (c)(2) of this chapter (when 
applicable) must be considered a separate type for the purposes of 
calculating a fuel economy label for a manufacturer's average fuel 
economy.
    (c) If, based on review of the information submitted under Sec.  
600.006(b), the Administrator determines that a fuel economy data 
vehicle meets the requirements of this section, the fuel economy data 
vehicle will be judged to be acceptable and fuel economy and carbon-
related exhaust emissions data from that fuel economy data vehicle will 
be reviewed pursuant to Sec.  600.008.
    (d) If, based on the review of the information submitted under Sec.  
600.006(b), the Administrator determines that a fuel economy data 
vehicle does not meet the requirements of this section, the 
Administrator will reject that fuel economy data vehicle and inform the 
manufacturer of the rejection in writing.
    (e) If, based on a review of the emission data for a fuel economy 
data vehicle, submitted under Sec.  600.006(b), or emission data 
generated by a vehicle tested under Sec.  600.008(e), the Administrator 
finds an indication of non-compliance with section 202 of the Clean

[[Page 885]]

Air Act, 42 U.S.C. 1857 et seq. of the regulation thereunder, he may 
take such investigative actions as are appropriate to determine to what 
extent emission non-compliance actually exists.
    (1) The Administrator may, under the provisions of Sec.  86.1830 of 
this chapter, request the manufacturer to submit production vehicles of 
the configuration(s) specified by the Administrator for testing to 
determine to what extent emission noncompliance of a production vehicle 
configuration or of a group of production vehicle configurations may 
actually exist.
    (2) If the Administrator determines, as a result of his 
investigation, that substantial emission non-compliance is exhibited by 
a production vehicle configuration or group of production vehicle 
configurations, he may proceed with respect to the vehicle 
configuration(s) as provided under section 206 or 207, as applicable, of 
the Clean Air Act, 42 U.S.C. 1857 et seq.
    (f) All vehicles used to generate fuel economy and carbon-related 
exhaust emissions data, and for which emission standards apply, must be 
covered by a certificate of conformity under part 86 of this chapter 
before:
    (1) The data may be used in the calculation of any approved general 
or specific label value, or
    (2) The data will be used in any calculations under subpart F, 
except that vehicles imported under Sec. Sec.  85.1509 and 85.1511 of 
this chapter need not be covered by a certificate of conformity.

Sec.  600.008  Review of fuel economy, CO2; emissions, and carbon-related 
exhaust emission data, testing by the Administrator.

    (a) Testing by the Administrator. (1)(i) The Administrator may 
require that any one or more of the test vehicles be submitted to the 
Agency, at such place or places as the Agency may designate, for the 
purposes of conducting fuel economy tests. The Administrator may specify 
that such testing be conducted at the manufacturer's facility, in which 
case instrumentation and equipment specified by the Administrator shall 
be made available by the manufacturer for test operations. The tests to 
be performed may comprise the FTP, highway fuel economy test, US06, 
SC03, or Cold temperature FTP or any combination of those tests. Any 
testing conducted at a manufacturer's facility pursuant to this 
paragraph shall be scheduled by the manufacturer as promptly as 
possible.
    (ii) Starting with the 2012 model year for carbon-related exhaust 
emissions and with the 2013 model year for CO2 emissions, the 
evaluations, testing, and test data described in this section pertaining 
to fuel economy shall also be performed for CO2 emissions and 
carbon-related exhaust emissions, except that CO2 emissions 
and carbon-related exhaust emissions shall be arithmetically averaged 
instead of harmonically averaged, and in cases where the manufacturer 
selects the lowest of several fuel economy results to represent the 
vehicle, the manufacturer shall select the CO2 emissions and 
carbon-related exhaust emissions value from the test results associated 
with the lowest selected fuel economy results.
    (2) Retesting and official data determination. For any vehicles 
selected for confirmatory testing under the provisions of paragraph 
(a)(1) of this section, the Administrator will follow this procedure:
    (i) The manufacturer's fuel economy data (or harmonically averaged 
data if more than one test was conducted) will be compared with the 
results of the Administrator's test.
    (ii) If, in the Administrator's judgment, the comparison in 
paragraph (a)(2)(i) of this section indicates a disparity in the data, 
the Administrator will repeat the test or tests as applicable.
    (A) The manufacturer's average test results and the results of the 
Administrator's first test will be compared with the results of the 
Administrator's second test as in paragraph (a)(2)(i) of this section.
    (B) If, in the Administrator's judgment, both comparisons in 
paragraph (a)(2)(i)(A) of this section, indicate a disparity in the 
data, the Administrator will repeat the applicable test or tests until:

[[Page 886]]

    (1) In the Administrator's judgment no disparity in the data is 
indicated by comparison of two tests by the Administrator or by 
comparison of the manufacturer's average test results and a test by the 
Administrator; or
    (2) Four tests of a single test type are conducted by the 
Administrator in which a disparity in the data is indicated when 
compared as in paragraph (a)(2)(ii) of this section.
    (iii) If there is, in the Administrator's judgment, no disparity 
indicated by comparison of manufacturer's average test results with a 
test by the Administrator, the test values generated by the 
Administrator will be used to represent the vehicle.
    (iv) If there is, in the Administrator's judgment, no disparity 
indicated by comparison of two tests by the Administrator, the harmonic 
averages of the fuel economy results from those tests will be used to 
represent the vehicle.
    (v) If the situation in paragraph (a)(2)(ii)(B)(2) of this section 
occurs, the Administrator will notify the manufacturer, in writing, that 
the Administrator rejects that fuel economy data vehicle.
    (b) Manufacturer-conducted confirmatory testing. (1) If the 
Administrator determines not to conduct a confirmatory test under the 
provisions of paragraph (a) of this section, manufacturers will conduct 
a confirmatory test at their facility after submitting the original test 
data to the Administrator whenever any of the following conditions 
exist:
    (i) The vehicle configuration has previously failed an emission 
standard;
    (ii) The test exhibits high emission levels determined by exceeding 
a percentage of the standards specified by the Administrator for that 
model year;
    (iii) The fuel economy value of the FTP or HFET test is higher than 
expected based on procedures approved by the Administrator;
    (iv) The fuel economy for the FTP or HFET test is close to a Gas 
Guzzler Tax threshold value based on tolerances established by the 
Administrator; or
    (v) The fuel economy value for the FTP or highway is a potential 
fuel economy leader for a class of vehicles based on cut points provided 
by the Administrator.
    (2) If the Administrator selects the vehicle for confirmatory 
testing based on the manufacturer's original test results, the testing 
shall be conducted as ordered by the Administrator. In this case, the 
manufacturer-conducted confirmatory testing specified under paragraph 
(b)(1) of this section would not be required.
    (3) The manufacturer shall conduct a retest of the FTP or highway 
test if the difference between the fuel economy of the confirmatory test 
and the original manufacturer's test equals or exceeds three percent (or 
such lower percentage to be applied consistently to all manufacturer-
conducted confirmatory testing as requested by the manufacturer and 
approved by the Administrator).
    (i) The manufacturer may, in lieu of conducting a retest, accept the 
lower of the original and confirmatory test fuel economy results for use 
in subpart C or F of this part.
    (ii) The manufacturer shall conduct a second retest of the FTP or 
highway test if the fuel economy difference between the second 
confirmatory test and the original manufacturer test equals or exceeds 
three percent (or such lower percentage as requested by the manufacturer 
and approved by the Administrator) and the fuel economy difference 
between the second confirmatory test and the first confirmatory test 
equals or exceeds three percent (or such lower percentage as requested 
by the manufacturer and approved by the Administrator). The manufacturer 
may, in lieu of conducting a second retest, accept the lowest of the 
original test, the first confirmatory test, and the second confirmatory 
test fuel economy results for use in subpart C or F of this part.
    (4) The Administrator may request the manufacturer to conduct a 
retest of the US06, SC03 or Cold Temperature FTP on the basis of fuel 
economy that is higher than expected as specified in criteria provided 
by the Administrator. Such retests shall not be required before the 2011 
model year.

[[Page 887]]

    (c) Review of fuel economy data. (1) Fuel economy data must be 
judged reasonable and representative by the Administrator in order for 
the test results to be used for the purposes of subpart C or F of this 
part. In making this determination, the Administrator will, when 
possible, compare the results of a test vehicle to those of other 
similar test vehicles.
    (2) If testing was conducted by the Administrator under the 
provisions of paragraph (a) of this section, the data from this testing, 
together with all other fuel economy data submitted for that vehicle 
under Sec.  600.006(c) or (e) will be evaluated by the Administrator for 
reasonableness and representativeness per paragraph (c)(1) of this 
section.
    (i) The fuel economy data which are determined to best meet the 
criteria of paragraph (c)(1) of this section will be accepted for use in 
subpart C or F of this part.
    (ii) City, HFET, US06, SC03 and Cold temperature FTP test data will 
be considered separately.
    (iii) If more than one test was conducted, the Administrator may 
select an individual test result or the harmonic average of selected 
test results to satisfy the requirements of paragraph (c)(2)(i) of this 
section.
    (3) If confirmatory testing was conducted by the manufacturer under 
the provisions of paragraph (b) of this section, the data from this 
testing will be evaluated by the Administrator for reasonableness and 
representativeness per paragraph (c)(1) of this section.
    (i) The fuel economy data which are determined to best meet the 
criteria of paragraph (c)(1) of this section will be accepted for use in 
subpart C or F of this part.
    (ii) City, HFET, US06, SC03 and Cold temperature FTP test data will 
be considered separately.
    (iii) If more than one test was conducted, the Administrator may 
select an individual test result or the harmonic average of selected 
test results to satisfy the requirements of paragraph (c)(2)(i) of this 
section.
    (4) If no confirmatory testing was conducted by either the 
Administrator or the manufacturer under the provisions of paragraph (a) 
and (b) of this section, respectively, then the data submitted under the

be considered separately.
    (ii) If more than one test was conducted, the harmonic average of 
the test results shall be accepted for use in subpart C or F of this 
part.
    (d) If, based on a review of the fuel economy data generated by 
testing under paragraph (a) of this section, the Administrator 
determines that an unacceptable level of correlation exists between fuel 
economy data generated by a manufacturer and fuel economy data generated 
by the Administrator, he/she may reject all fuel economy data submitted 
by the manufacturer until the cause of the discrepancy is determined and 
the validity of the data is established by the manufacturer.
    (e)(1) If, based on the results of an inspection conducted under 
Sec.  600.005(b) or any other information, the Administrator has reason 
to believe that the manufacturer has not followed proper testing 
procedures or that the testing equipment is faulty or improperly 
calibrated, or if records do not exist that will enable him to make a 
finding of proper testing, the Administrator may notify the manufacturer 
in writing of his finding and require the manufacturer to:
    (i) Submit the test vehicle(s) upon which the data are based or 
additional test vehicle(s) at a place he may designate for the purpose 
of fuel economy testing.
    (ii) Conduct such additional fuel economy testing as may be required 
to demonstrate that prior fuel economy test data are reasonable and 
representative.
    (2) Previous acceptance by the Administrator of any fuel economy 
test data submitted by the manufacturer shall not limit the 
Administrator's right to require additional testing under paragraph 
(e)(1) of this section.
    (3) If, based on tests required under paragraph (e)(1) of this 
section, the Administrator determines that any fuel economy data 
submitted by the manufacturer and used to calculate the manufacturer's 
fuel economy average was unrepresentative, the Administrator

[[Page 888]]

may recalculate the manufacturer's fuel economy average based on fuel 
economy data that he/she deems representative.
    (4) A manufacturer may request a hearing as provided in Sec.  
600.009 if the Administrator decides to recalculate the manufacturer's

Sec.  600.113-12  Fuel economy, CO2 emissions, and carbon-related 
exhaust emission calculations for FTP, HFET, US06, SC03 and cold temperature 
FTP tests.

    The Administrator will use the calculation procedure set forth in 
this paragraph for all official EPA testing of vehicles fueled with 
gasoline, diesel, alcohol-based or natural gas fuel. The calculations of 
the weighted fuel economy and carbon-related exhaust emission values 
require input of the weighted grams/mile values for total hydrocarbons 
(HC), carbon monoxide (CO), and carbon dioxide (CO2); and, 
additionally for methanol-fueled automobiles, methanol 
(CH3OH) and formaldehyde (HCHO); and, additionally for 
ethanol-fueled automobiles, methanol (CH3OH), ethanol 
(C2H5OH), acetaldehyde 
(C2H4O), and formaldehyde (HCHO); and additionally 
for natural gas-fueled vehicles, non-methane hydrocarbons (NMHC) and 
methane (CH4). For manufacturers selecting the fleet 
averaging option for N2O and CH4 as allowed under 
Sec.  86.1818 of this chapter the calculations of the carbon-related 
exhaust emissions require the input of grams/mile values for nitrous 
oxide (N2O) and methane (CH4). Emissions shall be 
determined for the FTP, HFET, US06, SC03 and cold temperature FTP tests. 
Additionally, the specific gravity, carbon weight fraction and net 
heating value of the test fuel must be determined. The FTP, HFET, US06, 
SC03 and cold temperature FTP fuel economy and carbon-related exhaust 
emission values shall be calculated as specified in this section. An 
example fuel economy calculation appears in Appendix II of this part.
    (a) Calculate the FTP fuel economy as follows:
    (1) Calculate the weighted grams/mile values for the FTP test for 
CO2, HC, and CO, and where applicable, CH3OH, 
C2H5OH, C2H4O, HCHO, NMHC, 
N2O, and CH4 as specified in 40 CFR 1066.605. 
Measure and record the test fuel's properties as specified in paragraph 
(f) of this section.
    (2) Calculate separately the grams/mile values for the cold 
transient phase, stabilized phase and hot transient phase of the FTP 
test. For vehicles with more than one source of propulsion energy, one 
of which is a rechargeable energy storage system, or vehicles with 
special features that the Administrator determines may have a 
rechargeable energy source, whose charge can vary during the test, 
calculate separately the grams/mile values for the cold transient phase, 
stabilized phase, hot transient phase and hot stabilized phase of the 
FTP test.
    (b) Calculate the HFET fuel economy as follows:
    (1) Calculate the mass values for the highway fuel economy test for 
HC, CO, and CO2, and where applicable, CH3OH, 
C2H5OH, C2H4O, HCHO, NMHC, 
N2O, and CH4 as specified in 40 CFR 1066.605.

[[Page 892]]

Measure and record the test fuel's properties as specified in paragraph 
(f) of this section.
    (2) Calculate the grams/mile values for the highway fuel economy 
test for HC, CO, and CO2, and where applicable 
CH3OH, C2H5OH, 
C2H4O, HCHO, NMHC, N2O, and 
CH4 by dividing the mass values obtained in paragraph (b)(1) 
of this section, by the actual driving distance, measured in miles, as 
specified in 40 CFR 1066.840.
    (c) Calculate the cold temperature FTP fuel economy as follows:
    (1) Calculate the weighted grams/mile values for the cold 
temperature FTP test for HC, CO, and CO2, and where 
applicable, CH3OH, C2H5OH, 
C2H4O, HCHO, NMHC, N2O, and 
CH4 as specified in 40 CFR 1066.605.
    (2) Calculate separately the grams/mile values for the cold 
transient phase, stabilized phase and hot transient phase of the cold 
temperature FTP test as specified in 40 CFR 1066.605.
    (3) Measure and record the test fuel's properties as specified in 
paragraph (f) of this section.
    (d) Calculate the US06 fuel economy as follows:
    (1) Calculate the total grams/mile values for the US06 test for HC, 
CO, and CO2, and where applicable, CH3OH, 
C2H5OH, C2H4O, HCHO, NMHC, 
N2O, and CH4 as specified in 40 CFR 1066.605.
    (2) Calculate separately the grams/mile values for HC, CO, and 
CO2, and where applicable, CH3OH, 
C2H5OH, C2H4O, HCHO, NMHC, 
N2O, and CH4, for both the US06 City phase and the 
US06 Highway phase of the US06 test as specified in 40 CFR 1066.605 and 
1066.831. In lieu of directly measuring the emissions of the separate 
city and highway phases of the US06 test according to the provisions of 
40 CFR 1066.831, the manufacturer may optionally, with the advance 
approval of the Administrator and using good engineering judgment, 
analytically determine the grams/mile values for the city and highway 
phases of the US06 test. To analytically determine US06 City and US06 
Highway phase emission results, the manufacturer shall multiply the US06 
total grams/mile values determined in paragraph (d)(1) of this section 
by the estimated proportion of fuel use for the city and highway phases 
relative to the total US06 fuel use. The manufacturer may estimate the 
proportion of fuel use for the US06 City and US06 Highway phases by 
using modal CO2, HC, and CO emissions data, or by using 
appropriate OBD data (e.g., fuel flow rate in grams of fuel per second), 
or another method approved by the Administrator.
    (3) Measure and record the test fuel's properties as specified in 
paragraph (f) of this section.
    (e) Calculate the SC03 fuel economy as follows:
    (1) Calculate the grams/mile values for the SC03 test for HC, CO, 
and CO2, and where applicable, CH3OH, 
C2H5OH, C2H4O, HCHO, NMHC, 
N2O, and CH4 as specified in 40 CFR 1066.605.
    (2) Measure and record the test fuel's properties as specified in 
paragraph (f) of this section.
    (f) Analyze and determine fuel properties as follows:
    (1) Gasoline test fuel properties shall be determined by analysis of 
a fuel sample taken from the fuel supply. A sample shall be taken after 
each addition of fresh fuel to the fuel supply. Additionally, the fuel 
shall be resampled once a month to account for any fuel property changes 
during storage. Less frequent resampling may be permitted if EPA 
concludes, on the basis of manufacturer-supplied data, that the 
properties of test fuel in the manufacturer's storage facility will 
remain stable for a period longer than one month. The fuel samples shall 
be analyzed to determine the following fuel properties:
    (i) Specific gravity measured using ASTM D 1298 (incorporated by 
reference in Sec.  600.011).
    (ii) Carbon weight fraction measured using ASTM D 3343 (incorporated 
by reference in Sec.  600.011).
    (iii) Net heating value (Btu/lb) determined using ASTM D 3338/D 
3338M (incorporated by reference in Sec.  600.011).
    (2) Methanol test fuel shall be analyzed to determine the following 
fuel properties:
    (i) Specific gravity using ASTM D 1298 (incorporated by reference in 
Sec.  600.011). You may determine specific gravity for the blend, or you 
may determine specific gravity for the gasoline and methanol fuel 
components

[[Page 893]]

separately before combining the results using the following equation:

SG = SGg x volume fraction gasoline + SGm x volume fraction methanol.

    (ii)(A) Carbon weight fraction using the following equation:

CWF = CWFg x MFg + 0.375 x MFm

Where:

CWFg = Carbon weight fraction of gasoline portion of blend measured 
          using ASTM D 3343 (incorporated by reference in Sec.  
          600.011).
MFg = Mass fraction gasoline = (G x SGg)/(G x SGg + M x SGm)
MFm = Mass fraction methanol = (M x SGm)/(G x SGg + M x SGm)

Where:

G = Volume fraction gasoline.
M = Volume fraction methanol.
SGg = Specific gravity of gasoline as measured using ASTM D 1298 
          (incorporated by reference in Sec.  600.011).
SGm = Specific gravity of methanol as measured using ASTM D 1298 
          (incorporated by reference in Sec.  600.011).

    (B) Upon the approval of the Administrator, other procedures to 
measure the carbon weight fraction of the fuel blend may be used if the 
manufacturer can show that the procedures are superior to or equally as 
accurate as those specified in this paragraph (f)(2)(ii).
    (3) Natural gas test fuel shall be analyzed to determine the 
following fuel properties:
    (i) Fuel composition measured using ASTM D 1945 (incorporated by 
reference in Sec.  600.011).
    (ii) Specific gravity measured as based on fuel composition per ASTM 
D 1945 (incorporated by reference in Sec.  600.011).
    (iii) Carbon weight fraction, based on the carbon contained only in 
the hydrocarbon constituents of the fuel. This equals the weight of 
carbon in the hydrocarbon constituents divided by the total weight of 
fuel.
    (iv) Carbon weight fraction of the fuel, which equals the total 
weight of carbon in the fuel (i.e., includes carbon contained in 
hydrocarbons and in CO2) divided by the total weight of fuel.
    (4) Ethanol test fuel shall be analyzed to determine the following 
fuel properties:
    (i) Specific gravity using ASTM D 1298 (incorporated by reference in 
Sec.  600.011). You may determine specific gravity for the blend, or you 
may determine specific gravity for the gasoline and methanol fuel 
components separately before combining the results using the following

Sec.  600.115-11  Criteria for determining the fuel economy label 
calculation method.

    This section provides the criteria to determine if the derived 5-
cycle method for determining fuel economy label values, as specified in 
Sec.  600.210-08(a)(2) or (b)(2) or Sec.  600.210-12(a)(2) or (b)(2), as 
applicable, may be used to determine label values. Separate criteria 
apply to city and highway fuel economy for each test group. The 
provisions of this section are optional. If this option is not chosen, 
or if the criteria provided in this section are not met, fuel economy 
label values must be determined according to the vehicle-specific 5-
cycle method specified in Sec.  600.210-08(a)(1) or (b)(1) or Sec.  
600.210-12(a)(1) or (b)(1), as applicable. However, dedicated 
alternative-fuel vehicles (other than battery electric vehicles and fuel 
cell vehicles), dual fuel vehicles when operating on the alternative 
fuel, MDPVs, and vehicles imported by Independent Commercial Importers 
may use the derived 5-cycle method for determining fuel economy label 
values whether or not the criteria provided in this section are met. 
Manufacturers may alternatively account for this effect for battery 
electric vehicles, fuel cell vehicles, and plug-in hybrid electric 
vehicles (when operating in the charge-depleting mode) by multiplying 2-
cycle fuel economy values by 0.7 and dividing 2-cycle CO2 
emission values by 0.7.
    (a) City fuel economy criterion. (1) For each test group certified 
for emission compliance under Sec.  86.1848 of this chapter, the FTP, 
HFET, US06, SC03 and Cold FTP tests determined to be official under 
Sec.  86.1835 of this chapter are used to calculate the vehicle-specific 
5-cycle city fuel economy which is then compared to the derived 5-cycle 
city fuel economy, as follows:
    (i) The vehicle-specific 5-cycle city fuel economy from the official 
FTP, HFET, US06, SC03 and Cold FTP tests for the test group is 
determined according to the provisions of Sec.  600.114-08(a) or (c) or 
Sec.  600.114-12(a) or (c) and rounded to the nearest one tenth of a 
mile per gallon.
    (ii) Using the same FTP data as used in paragraph (a)(1)(i) of this 
section, the corresponding derived 5-cycle city fuel economy is 
calculated according to the following equation:

[[Page 913]]

[GRAPHIC] [TIFF OMITTED] TR06JY11.033

Where:

City Intercept = Intercept determined by the Administrator. See Sec.  
          600.210-08(a)(2)(iii) or Sec.  600.210-12(a)(2)(iii).
City Slope = Slope determined by the Administrator. See Sec.  600.210-
          08(a)(2)(iii) or Sec.  600.210-12(a)(2)(ii).
FTP FE = the FTP-based city fuel economy from the official test used for 
          certification compliance, determined under Sec.  600.113-
          08(a), rounded to the nearest tenth.

    (2) The derived 5-cycle fuel economy value determined in paragraph 
(a)(1)(ii) of this section is multiplied by 0.96 and rounded to the 
nearest one tenth of a mile per gallon.
    (3) If the vehicle-specific 5-cycle city fuel economy determined in 
paragraph (a)(1)(i) of this section is greater than or equal to the 
value determined in paragraph (a)(2) of this section, then the 
manufacturer may base the city fuel economy estimates for the model 
types covered by the test group on the derived 5-cycle method specified 
in Sec.  600.210-08(a)(2) or (b)(2) or Sec.  600.210-12(a)(2) or (b)(2), 
as applicable.
    (b) Highway fuel economy criterion. The determination for highway 
fuel economy depends upon the outcome of the determination for city fuel 
economy in paragraph (a)(3) of this section for each test group.
    (1) If the city determination for a test group made in paragraph 
(a)(3) of this section does not allow the use of the derived 5-cycle 
method, then the highway fuel economy values for all model types 
represented by the test group are likewise not allowed to be determined 
using the derived 5-cycle method, and must be determined according to 
the vehicle-specific 5-cycle method specified in Sec.  600.210-08(a)(1) 
or (b)(1) or Sec.  600.210-12(a)(1) or (b)(1), as applicable.
    (2) If the city determination made in paragraph (a)(3) of this 
section allows the use of the derived 5-cycle method, a separate 
determination is made for the highway fuel economy labeling method as 
follows:
    (i) For each test group certified for emission compliance under 
Sec.  86.1848 of this chapter, the FTP, HFET, US06, SC03 and Cold FTP 
tests determined to be official under Sec.  86.1835 of this chapter are 
used to calculate the vehicle-specific 5-cycle highway fuel economy, 
which is then compared to the derived 5-cycle highway fuel economy, as 
follows:
    (A) The vehicle-specific 5-cycle highway fuel economy from the 
official FTP, HFET, US06, SC03 and Cold FTP tests for the test group is 
determined according to the provisions of Sec.  600.114-08(b)(1) or 
Sec.  600.114-12(b)(1) and rounded to the nearest one tenth of a mile 
per gallon.
    (B) Using the same HFET data as used in paragraph (b)(2)(i)(A) of 
this section, the corresponding derived 5-cycle highway fuel economy is 
calculated using the following equation:
[GRAPHIC] [TIFF OMITTED] TR06JY11.034

Where:
Highway Intercept = Intercept determined by the Administrator. See Sec.  
          600.210-08(a)(2)(iii) or Sec.  600.210-12(a)(2)(iii).
Highway Slope = Slope determined by the Administrator. See Sec.  
          600.210-08(a)(2)(iii) or Sec.  600.210-12(a)(2)(iii).

[[Page 914]]

HFET FE = the HFET-based highway fuel economy determined under Sec.  
          600.113-08(b), rounded to the nearest tenth.

    (ii) The derived 5-cycle highway fuel economy calculated in 
paragraph (b)(2)(i)(B) of this section is multiplied by 0.95 and rounded 
to the nearest one tenth of a mile per gallon.
    (iii) (A) If the vehicle-specific 5-cycle highway fuel economy of 
the vehicle tested in paragraph (b)(2)(i)(A) of this section is greater 
than or equal to the value determined in paragraph (b)(2)(ii) of this 
section, then the manufacturer may base the highway fuel economy 
estimates for the model types covered by the test group on the derived 
5-cycle method specified in Sec.  600.210-08(a)(2) or (b)(2) or Sec.  
600.210-12(a)(2) or (b)(2), as applicable.
    (B) If the vehicle-specific 5-cycle highway fuel economy determined 
in paragraph (b)(2)(i)(A) of this section is less than the value 
determined in paragraph (b)(2)(ii) of this section, the manufacturer may 
determine the highway fuel economy for the model types covered by the 
test group on the modified 5-cycle equation specified in Sec.  600.114-
08(b)(2) or Sec.  600.114-12(b)(2).
    (c) The manufacturer will apply the criteria in paragraph (a) and 
(b) of this section to every test group for each model year.
    (d) The tests used to make the evaluations in paragraphs (a) and (b) 
of this section will be the procedures for official test determinations 
under Sec.  86.1835. Adjustments and/or substitutions to the official 
test data may be made with advance approval of the Administrator.

Sec.  600.116-12  Special procedures related to electric vehicles 
and hybrid electric vehicles.

    (a) Determine fuel economy values for electric vehicles as specified 
in Sec. Sec.  600.210 and 600.311 using the procedures of SAE J1634 
(incorporated by reference in Sec.  600.011). Use the procedures of SAE 
J1634, Section 8, with the following clarifications and modifications 
for using this and other sections of SAE J1634:
    (1) Vehicles that cannot complete the Multi-Cycle Range and Energy 
Consumption Test (MCT) because they are unable travel the distance 
required to complete the test with a fully charged battery, or they are 
unable to achieve the maximum speed on either the UDDS or HFEDS (Highway 
Fuel Economy Drive Cycle also known as the HFET) cycle should seek 
Administrator approval to use the procedures outlined in SAE J1634 
Section 7 Single Cycle Range and Energy Consumption Test (SCT).
    (2) The MCT includes the following key-on soak times and key-off 
soak periods:
    (i) As noted in SAE J1634 Section 8.3.4, a 15 second key-on pause is 
required between UDDS1 and HFEDS1, and 
UDDS3 and HFEDS2.
    (ii) As noted in SAE J1634 Section 8.3.4, a 10-minute key-off soak 
period is required between HFEDS1 and UDDS2, and 
HFEDS2 and UDDS4.
    (iii) A key-off soak period up to 30 minutes may be inserted between 
UDDS2 and the first phase of the mid-test constant speed 
cycle, between UDDS4 and the first phase of the end-of-test 
constant speed cycle, and between the end of the mid-test constant speed 
cycle and UDDS3. Start the next test segment immediately if 
there is no key-off soak between test segments.
    (iv) If multiple phases are required during either the mid-test 
constant speed cycle or the end-of-test constant speed cycle there must 
be a 5-minute to 30-minute key-off soak period between each constant 
speed phase as noted in SAE J1634 Section 6.6.
    (3) As noted in SAE J1634 Section 8.3.4, during all `key-off' soak 
periods, the key or power switch must be in the ``off'' position, the 
hood must be closed, the test cell fan(s) must be off, and the brake 
pedal not depressed. For vehicles which do not have a key or power 
switch the vehicle must be placed in the `mode' the manufacturer 
recommends when the vehicle is to be parked and the occupants exit the 
vehicle.
    (4) Manufacturers may determine the mid-test constant speed cycle 
distance (dM) using their own methodology and good 
engineering judgment. Otherwise, either Method 1 or Method 2 described 
in Appendix A of SAE J1634 may be used to estimate the mid-test constant

[[Page 915]]

speed cycle distance (dM). The mid-test constant speed cycle 
distance calculation needs to be performed prior to beginning the test 
and should not use data from the test being performed. If Method 2 is 
used, multiply the result determined by the Method 2 equation by 0.8 to 
determine the mid-test constant speed cycle distance (dM).
    (5) Divide the mid-test constant speed cycle distance 
(dM) by 65 mph to determine the total time required for the 
mid-test constant speed cycle. If the time required is one hour or less, 
the mid-test constant speed cycle can be performed with no key-off soak 
periods. If the time required is greater than one hour, the mid-test 
constant speed cycle must be separated into phases such that no phase 
exceeds more than one hour. At the conclusion of each mid-test constant 
speed phase, except at the conclusion of the mid-test constant speed 
cycle, perform a 5-minute to 30-minute key-off soak. A key-off soak 
period up to 30 minutes may be inserted between the end of the mid-test 
constant speed cycle and UDDS3.
    (6) Using good engineering judgment determine the end-of-test 
constant speed cycle distance so that it does not exceed 20% of the 
total distance driven during the MCT as described in SAE J1634 Section 
8.3.3.
    (7) Divide the end-of-test constant speed cycle distance 
(dE) by 65 mph to determine the total time required for the 
end-of-test constant speed cycle. If the time required is one-hour or 
less the end-of-test constant speed cycle can be performed with no key-
off soak periods. If the time required is greater than one-hour the end-
of-test constant speed cycle must be separated into phases such that no 
phase exceeds more than one-hour. At the conclusion of each end-of-test 
constant speed phase, perform a 5-minute to 30-minute key-off soak.
    (8) SAE J1634 Section 3.13 defines useable battery energy (UBE) as 
the total DC discharge energy (Edctotal), measured in DC 
watt-hours for a full discharge test. The total DC discharge energy is 
the sum of all measured phases of a test inclusive of all drive cycle 
types. As key-off soak periods are not considered part of the test 
phase, the discharge energy that occurs during the key-off soak periods 
is not included in the useable battery energy.
    (9) Recharging the vehicle's battery must start within three hours 
after the end of testing.
    (10) At the request of a manufacturer, the Administrator may approve 
the use of an earlier version of SAE J1634 when a manufacturer is 
carrying over data for vehicles tested using a prior version of SAE 
J1634.
    (11) All label values related to fuel economy, energy consumption, 
and range must be based on 5-cycle testing or on values adjusted to be 
equivalent to 5-cycle results. Prior to performing testing to generate a 
5-cycle adjustment factor, manufacturers must request Administrator 
approval to use SAE J1634 Appendices B and C for determining a 5-cycle 
adjustment factor with the following modifications, clarifications, and 
attestations:
    (i) Before model year 2025, prior to performing the 20 [deg]F 
charge-depleting UDDS, the vehicle must soak for a minimum of 12 hours 
and a maximum of 36 hours at a temperature of 20 [deg]F. Prior to 
beginning the 12 to 36 hour cold soak at 20 [deg]F the vehicle must be 
fully charged, the charging can take place at test laboratory ambient 
temperatures (68 to 86 [deg]F) or at 20 [deg]F. During the 12 to 36 hour 
cold soak period the vehicle may not be connected to a charger nor is 
the vehicle cabin or battery to be preconditioned during the 20 [deg]F 
soak period.
    (ii) Beginning with model year 2025, the 20 [deg]F UDDS charge-
depleting UDDS test will be replaced with a 20 [deg]F UDDS test 
consisting of two UDDS cycles performed with a 10-minute key-off soak 
between the two UDDS cycles. The data from the two UDDS cycles will be 
used to calculate the five-cycle adjustment factor, instead of using the 
results from the entire charge-depleting data set. Manufacturers that 
have submitted and used the average data from 20 [deg]F charge-depleting 
UDDS data sets will be required to revise their 5-cycle adjustment 
factor calculation and re-label vehicles using the data from the first 
two UDDS cycles only. Manufacturers, at their discretion, would also be 
allowed to re-run the 20 [deg]F UDDS test with the battery charged to a

[[Page 916]]

state-of-charge (SoC) determined by the manufacturer. The battery does 
not need to be at 100% SoC before the 20 [deg]F cold soak.
    (iii) Manufacturers must submit a written attestation to the 
Administrator at the completion of testing with the following 
information:
    (A) A statement noting the SoC level of the rechargeable energy 
storage system (RESS) prior to beginning the 20 [deg]F cold soak for 
testing performed beginning with model year 2025.
    (B) A statement confirming the vehicle was not charged or 
preconditioned during the 12 to 36 hour 20 [deg]F soak period before 
starting the 20 [deg]F UDDS cycle.
    (C) A summary of all the 5-cycle test results and the calculations 
used to generate the 5-cycle adjustment factor, including all the 20 
[deg]F UDDS cycles, the distance travelled during each UDDS and the 
measured DC discharge energy during each UDDS phase. Beginning in model 
year 2025, the 20 [deg]F UDDS test results will consist of only two UDDS 
cycles.
    (D) Beginning in model year 2025, calculate City Fuel Economy using 
the following equation for RunningFC instead of the equation on Page 30 
in Appendix C of SAE J1634:
[GRAPHIC] [TIFF OMITTED] TR24JA23.007

    (E) A description of each test group and configuration which will 
use the 5-cycle adjustment factor, including the battery capacity of the 
vehicle used to generate the 5-cycle adjustment factor and the battery 
capacity of all the configurations to which it will be applied.
    (iv) At the conclusion of the manufacturers testing and after 
receiving the attestations from the manufacturer regarding the 
performance of the 20 [deg]F UDDS test processes, the 5-cycle test 
results, and the summary of vehicles to which the manufacturer proposes 
applying the 5-cycle adjustment factor, the Administrator will review 
the submittals and inform the manufacturer in writing if the 
Administrator concurs with the manufacturer's proposal. If not, the 
Administrator will describe the rationale to the manufacturer for not 
approving their request.
    (b) Determine performance values for hybrid electric vehicles that 
have no plug-in capability as specified in Sec. Sec.  600.210 and 
600.311 using the procedures for charge-sustaining operation from SAE 
J1711 (incorporated by reference in Sec.  600.011). We may approve 
alternate measurement procedures with respect to these vehicles if that 
is necessary or appropriate for meeting the objectives of this part. For 
example, we may approve alternate Net Energy Change tolerances for 
charge-sustaining operation as described in paragraph (c)(5) of this 
section.
    (c) Determine performance values for hybrid electric vehicles that 
have plug-in capability as specified in Sec. Sec.  600.210 and 600.311 
using the procedures of SAE J1711 (incorporated by reference in Sec.  
600.011), with the following clarifications and modifications:
    (1) To determine CREE values to demonstrate compliance with GHG 
standards, calculate composite values representing combined operation 
during charge-depleting and charge-sustaining operation using the 
following utility factors except as specified in this paragraph (c):

    (2) Determine fuel economy values to demonstrate compliance with 
CAFE standards as follows:
    (i) For vehicles that are not dual fueled automobiles, determine 
fuel economy using the utility factors described in paragraph (c)(1) of 
this section. Do not use the petroleum-equivalence factors described in 
10 CFR 474.3.
    (ii) Except as described in paragraph (c)(2)(iii) of this section, 
determine fuel economy for dual fueled automobiles from the following 
equation, separately for city and highway driving:
[GRAPHIC] [TIFF OMITTED] TR25OC16.043

Where:

MPGgas = The miles per gallon measured while operating on 
          gasoline during charge-sustaining operation as determined 
          using the procedures of SAE J1711.
MPGeelec = The miles per gallon equivalent measured while 
          operating on electricity. Calculate this value by dividing the 
          equivalent all-electric range determined from the equation in 
          Sec.  86.1866-12(b)(2)(ii) by the corresponding measured Watt-
          hours of energy consumed; apply the appropriate petroleum-
          equivalence factor from 10 CFR 474.3 to convert Watt-hours to 
          gallons equivalent. Note that if vehicles use no gasoline 
          during charge-depleting operation, MPGeelec is the 
          same as the charge-depleting fuel economy specified in SAE 
          J1711.

    (iii) For 2016 and later model year dual fueled automobiles, you may 
determine fuel economy based on the following equation, separately for 
city and highway driving:
[GRAPHIC] [TIFF OMITTED] TR25OC16.044


[[Page 918]]


Where:

UF = The appropriate utility factor for city or highway driving as 
          described in paragraph (c)(1) of this section.

    (3) To determine fuel economy and CO2 emission values for 
labeling purposes, calculate composite values representing combined 
operation during charge-depleting and charge-sustaining operation using 
the following utility factors except as specified in this paragraph (c):

    (4) You may calculate performance values under paragraphs (c)(1) 
through (3) of this section by combining phases during FTP testing. For 
example, you may treat the first 7.45 miles as a single phase by adding 
the individual utility factors for that portion of driving and assigning 
emission levels to the combined phase. Do this consistently throughout a 
test run.
    (5) Instead of the utility factors specified in paragraphs (c)(1) 
through (3) of this section, calculate utility factors using the 
following equation for vehicles whose maximum speed is less than the 
maximum speed specified in the driving schedule, where the vehicle's 
maximum speed is determined, to the nearest 0.1 mph, from observing the 
highest speed over the first duty cycle (FTP, HFET, etc.):

Where:

UFi = the utility factor for phase i. Let UF0 = 0.
j = a counter to identify the appropriate term in the summation (with 
          terms numbered consecutively).
k = the number of terms in the equation (see Table 3 of this section).
di = the distance driven in phase i.
ND = the normalized distance. Use 399 for both FTP and HFET operation.
Cj = the coefficient for term j from the following table:

n = the number of test phases (or bag measurements) before the vehicle 
          reaches the end-of-test criterion.

    (6) The End-of-Test criterion is based on a 1 percent Net Energy 
Change as specified in Section 3.8 of SAE J1711. We may approve 
alternate Net Energy Change tolerances as specified in Section 3.9.1 of 
SAE J1711 for charge-depleting tests or Appendix C of SAE J1711 for 
charge-sustaining tests if the 1 percent threshold is insufficient or 
inappropriate. For charge-sustaining tests, we may approve the use of 
alternate Net Energy Change tolerances as specified in Appendix C of SAE 
J1711 to correct final fuel economy values, CO2 emissions, 
and carbon-related exhaust emissions. For charge-sustaining tests, do 
not use alternate Net Energy Change tolerances to correct emissions of 
criteria pollutants. Additionally, if we approve an alternate End-of-
Test criterion or Net Energy Change tolerances for a specific vehicle, 
we may use the alternate criterion or tolerances for any testing we 
conduct on that vehicle.
    (7) Use the vehicle's Actual Charge-Depleting Range, 
Rcda, as specified in Section 6.1.3 for evaluating the end-
of-test criterion.
    (8) Measure and record AC watt-hours throughout the recharging 
procedure. Position the measurement appropriately to account for any 
losses in the charging system.
    (9) We may approve alternate measurement procedures with respect to 
plug-in hybrid electric vehicles if they are necessary or appropriate 
for meeting the objectives of this part.
    (10) The utility factors described in this paragraph (c) are derived 
from equations in SAE J2841. You may alternatively calculate utility 
factors directly from the corresponding equations in SAE J2841.
    (d) Determining the proportion of recovered energy for hybrid 
electric vehicles. Testing of hybrid electric vehicles under this part 
may include a determination of the proportion of energy recovered over 
the FTP relative to the total available braking energy required over the 
FTP. This determination is required for pickup trucks accruing credits 
for implementation of hybrid technology under Sec.  86.1870-12, and 
requires the measurement of electrical current (in amps) flowing into 
the hybrid system battery for the duration of the test. Hybrid electric 
vehicles are tested for fuel economy and GHG emissions using the 4-bag 
FTP as required by Sec.  600.114(c). Alternative measurement and 
calculation methods may be used with prior EPA approval.
    (1) Calculate the theoretical maximum amount of energy that could be 
recovered by a hybrid electric vehicle over the FTP test cycle, where 
the test cycle time and velocity points are expressed at 10 Hz, and the 
velocity

[[Page 920]]

(miles/hour) is expressed to the nearest 0.01 miles/hour, as follows:
    (i) For each time point in the 10 Hz test cycle (i.e., at each 0.1 
seconds):
    (A) Determine the road load power in kilowatts using the following 
equation:
[GRAPHIC] [TIFF OMITTED] TR15OC12.056

Where:

Proadload is the road load power in kilowatts, where road 
          load is negative because it always represents a deceleration 
          (i.e., resistive) force on the vehicle;
A, B, and C are the vehicle-specific dynamometer road load coefficients 
          in lb-force, lb-force/mph, and lb-force/mph\2\, respectively;
Vmph = velocity in miles/hour, expressed to the nearest 0.01 
          miles/hour;
0.44704 converts speed from miles/hour to meters/second;
4.448 converts pound force to Newtons; and
1,000 converts power from Watts to kilowatts.

    (B) Determine the applied deceleration power at each sampling point 
in time, t, in kilowatts, using the following equation. Positive values 
indicate acceleration and negative values indicate deceleration.
[GRAPHIC] [TIFF OMITTED] TR15OC12.057

Where:

ETW = the vehicle Equivalent Test Weight (lbs);
Vt = velocity in miles/hour, rounded to the nearest 0.01 
          miles/hour, at each sampling point;
Vt-1 = the velocity in miles/hour at the previous time point 
          in the 10 Hz speed vs. time table, rounded to the nearest 0.01 
          miles/hour;
0.1 represents the time in seconds between each successive velocity data 
          point;
0.44704 converts speed from miles/hour to meters/second;
2.205 converts weight from pounds to kilograms; and
1,000 converts power from Watts to kilowatts.

    (C) Determine braking power in kilowatts using the following 
equation. Note that during braking events, Pbrake, 
Paccel, and Proadload will all be negative (i.e., 
resistive) forces on the vehicle.

Pbrake = Paccel-Proadload

Where:

Paccel = the value determined in paragraph (d)(1)(i)(B) of 
          this section;
Proadload = the value determined in paragraph (d)(1)(i)(A) of 
          this section; and
Pbrake = 0 if Paccel is greater than or equal to 
          Proadload.

    (ii) The total maximum braking energy (Ebrake) that could 
theoretically be recovered is equal to the absolute value of the sum of 
all the values of Pbrake determined in paragraph (d)(1)(i)(C) 
of this section, divided by 36000 (to convert 10 Hz data to hours) and 
rounded to the nearest 0.01 kilowatt-hours.
    (ii) The total maximum braking energy (Ebrake) that could 
theoretically be recovered is equal to the absolute value of the sum of 
all the values of Pbrake determined in paragraph (c)(1)(i)(C) 
of this section, divided by 36000 (to convert 10 Hz data to hours) and 
rounded to the nearest 0.01 kilowatt hours.
    (2) Calculate the actual amount of energy recovered 
(Erec) by a hybrid electric vehicle when tested on the FTP 
according to the provisions of this part, as follows:
    (i) Measure the electrical current in Amps to and from the hybrid 
electric

[[Page 921]]

vehicle battery during the FTP. Measurements should be made directly 
upstream of the battery at a 10 Hz sampling rate.
    (ii) At each sampling point where current is flowing into the 
battery, calculate the energy flowing into the battery, in Watt-hours, 
as follows:
[GRAPHIC] [TIFF OMITTED] TR25OC16.045

Where:

Et = the energy flowing into the battery, in Watt-hours, at 
          time t in the test;
It = the electrical current, in Amps, at time t in the test; 
          and
Vnominal = the nominal voltage of the hybrid battery system 
          determined according to paragraph (d)(4) of this section.

    (iii) The total energy recovered (Erec) is the absolute 
value of the sum of all values of Et that represent current 
flowing into the battery, divided by 1000 (to convert Watt-hours to 
kilowatt-hours).
    (3) The percent of braking energy recovered by a hybrid system 
relative to the total available energy is determined by the following 
equation, rounded to the nearest one percent:
[GRAPHIC] [TIFF OMITTED] TR25OC16.046

Where:

Erec = The actual total energy recovered, in kilowatt-hours, 
          as determined in paragraph (d)(2) of this section; and
Ebrake = The theoretical maximum amount of energy, in 
          kilowatt-hours, that could be recovered by a hybrid electric 
          vehicle over the FTP test cycle, as determined in paragraph 
          (d)(1) of this section.

    (4)(i) Determination nominal voltage (Vnominal) using the 
following equation:
[GRAPHIC] [TIFF OMITTED] TR15OC12.061

Where:

VS is the battery voltage measured at the start of the FTP 
          test, where the measurement is made after the key-on event but 
          not later than 10 seconds after the key-on event; and
VF is the battery voltage measured at the conclusion of the 
          FTP test, where the measurement is made before the key-off 
          event but not earlier than 10 seconds prior to the key-off 
          event.

    (ii) If the absolute value of the measured current to and from the 
battery during the measurement of either VS or VF 
exceeds three percent of the maximum absolute value of the current 
measured over the FTP, then that VS or VF value is 
not valid. If no valid voltage measurement can be made using this 
method, the manufacturer must develop an alternative method of 
determining nominal voltage. The alternative must be developed using 
good engineering judgment and is subject to EPA approval.

Sec.  600.117  Interim provisions.

    The following provisions apply instead of other provisions specified 
in this part through model year 2019:
    (a) Except as specified in paragraph (e) of this section, 
manufacturers must demonstrate compliance with greenhouse gas emission 
standards and determine fuel economy values using E0 gasoline test fuel 
as specified in 40 CFR 86.113-04(a)(1), regardless of any testing with 
Tier 3 test fuel under paragraph (b) of this section.
    (b) Manufacturers may demonstrate that vehicles comply with Tier 3 
emission standards as specified in 40 CFR part 86, subpart S, during 
fuel economy measurements using the E0 gasoline test fuel specified in 
40 CFR 86.113-04(a)(1), as long as this test fuel is used in fuel 
economy testing for all applicable duty cycles specified in 40 CFR part 
86, subpart S. If a vehicle fails to meet a Tier 3 emission standard 
using the E0 gasoline test fuel specified in 40 CFR 86.113-04(a)(1), the 
manufacturer must retest the vehicle using the Tier 3 test fuel 
specified in 40 CFR 1065.710(b) (or the equivalent LEV III test fuel for 
California) to demonstrate compliance with all applicable emission 
standards over that test cycle.
    (c) If a manufacturer demonstrates compliance with emission 
standards for criteria pollutants over all five test cycles using the 
Tier 3 test fuel specified in 40 CFR 1065.710(b) (or the equivalent LEV 
III test fuel for California), the manufacturer may use test data with 
the same test fuel to determine whether a test group meets the criteria 
described in Sec.  600.115 for derived 5-cycle testing for fuel economy 
labeling. Such vehicles may be tested over the FTP and HFET cycles with 
the E0 gasoline test fuel specified in 40 CFR 86.113-04(a)(1) under this 
paragraph (c); the vehicles must meet the Tier 3 emission standards over 
those test cycles as described in paragraph (b) of this section.
    (d) Manufacturers may perform testing with the appropriate gasoline 
test fuels specified in 40 CFR 86.113-04(a)(1), 40 CFR 86.213(a)(2), and 
in 40 CFR 1065.710(b) to evaluate whether their vehicles meet the 
criteria for derived 5-cycle testing under 40 CFR 600.115. All five 
tests must use test fuel with the same nominal ethanol concentration.
    (e) For IUVP testing under Sec.  86.1845, manufacturers may 
demonstrate compliance with greenhouse gas emission standards using a 
test fuel meeting specifications for demonstrating compliance with 
emission standards for criteria pollutants.

  Subpart C_Procedures for Calculating Fuel Economy and Carbon-Related 
                         Exhaust Emission Values



Sec.  600.206-12  Calculation and use of FTP-based and HFET-based 
fuel economy, CO2 emissions, and carbon-related exhaust emission values 
for vehicle configurations.

    (a) Fuel economy, CO2 emissions, and carbon-related 
exhaust emissions values determined for each vehicle under Sec.  
600.113-08(a) and (b) and as approved in Sec.  600.008 (c), are used to 
determine FTP-based city, HFET-based highway, and combined FTP/Highway-
based fuel economy, CO2 emissions, and carbon-related exhaust 
emission values for each vehicle configuration for which data are 
available. Note that fuel economy for some alternative fuel vehicles may 
mean miles per gasoline gallon equivalent and/or miles per unit of fuel 
consumed. For example, electric vehicles will determine miles per 
kilowatt-hour in addition to miles per gasoline gallon equivalent, and 
fuel cell vehicles will determine miles per kilogram of hydrogen.
    (1) If only one set of FTP-based city and HFET-based highway fuel 
economy values is accepted for a vehicle configuration, these values, 
rounded to the nearest tenth of a mile per gallon, comprise the city and 
highway fuel economy values for that configuration. If only one set of 
FTP-based city and HFET-based highway CO2 emissions and 
carbon-related exhaust emission values is accepted for a vehicle 
configuration, these values, rounded to the nearest gram per mile, 
comprise the city and highway CO2 emissions and carbon-
related exhaust emission values for that configuration.
    (2) If more than one set of FTP-based city and HFET-based highway 
fuel economy and/or carbon-related exhaust

[[Page 923]]

emission values are accepted for a vehicle configuration:
    (i) All data shall be grouped according to the subconfiguration for 
which the data were generated using sales projections supplied in 
accordance with Sec.  600.208-12(a)(3).
    (ii) Within each group of data, all fuel economy values are 
harmonically averaged and rounded to the nearest 0.0001 of a mile per 
gallon and all CO2 emissions and carbon-related exhaust 
emission values are arithmetically averaged and rounded to the nearest 
tenth of a gram per mile in order to determine FTP-based city and HFET-
based highway fuel economy, CO2 emissions, and carbon-related 
exhaust emission values for each subconfiguration at which the vehicle 
configuration was tested.
    (iii) All FTP-based city fuel economy, CO2 emissions, and 
carbon-related exhaust emission values and all HFET-based highway fuel 
economy and carbon-related exhaust emission values calculated in 
paragraph (a)(2)(ii) of this section are (separately for city and 
highway) averaged in proportion to the sales fraction (rounded to the 
nearest 0.0001) within the vehicle configuration (as provided to the 
Administrator by the manufacturer) of vehicles of each tested 
subconfiguration. Fuel economy values shall be harmonically averaged, 
and CO2 emissions and carbon-related exhaust emission values 
shall be arithmetically averaged. The resultant fuel economy values, 
rounded to the nearest 0.0001 mile per gallon, are the FTP-based city 
and HFET-based highway fuel economy values for the vehicle 
configuration. The resultant CO2 emissions and carbon-related 
exhaust emission values, rounded to the nearest tenth of a gram per 
mile, are the FTP-based city and HFET-based highway CO2 
emissions and carbon-related exhaust emission values for the vehicle 
configuration.
    (3)(i) For the purpose of determining average fuel economy under 
Sec.  600.510, the combined fuel economy value for a vehicle 
configuration is calculated by harmonically averaging the FTP-based city 
and HFET-based highway fuel economy values, as determined in paragraph 
(a)(1) or (2) of this section, weighted 0.55 and 0.45 respectively, and 
rounded to the nearest 0.0001 mile per gallon. A sample of this 
calculation appears in Appendix II of this part.
    (ii) For the purpose of determining average carbon-related exhaust 
emissions under Sec.  600.510, the combined carbon-related exhaust 
emission value for a vehicle configuration is calculated by 
arithmetically averaging the FTP-based city and HFET-based highway 
carbon-related exhaust emission values, as determined in paragraph 
(a)(1) or (2) of this section, weighted 0.55 and 0.45 respectively, and 
rounded to the nearest tenth of gram per mile.
    (4) For alcohol dual fuel automobiles and natural gas dual fuel 
automobiles the procedures of paragraphs (a)(1) or (2) of this section, 
as applicable, shall be used to calculate two separate sets of FTP-based 
city, HFET-based highway, and combined values for fuel economy, 
CO2 emissions, and carbon-related exhaust emissions for each 
configuration.
    (i) Calculate the city, highway, and combined fuel economy, 
CO2 emissions, and carbon-related exhaust emission values 
from the tests performed using gasoline or diesel test fuel.
    (ii) Calculate the city, highway, and combined fuel economy, 
CO2 emissions, and carbon-related exhaust emission values 
from the tests performed using alcohol or natural gas test fuel.
    (b) If only one equivalent petroleum-based fuel economy value exists 
for an electric vehicle configuration, that value, rounded to the 
nearest tenth of a mile per gallon, will comprise the petroleum-based 
fuel economy for that configuration.
    (c) If more than one equivalent petroleum-based fuel economy value 
exists for an electric vehicle configuration, all values for that 
vehicle configuration are harmonically averaged and rounded to the 
nearest 0.0001 mile per gallon for that configuration.

Sec.  600.207-12  Calculation and use of vehicle-specific 5-cycle-based 
fuel economy and C2  emission values for vehicle configurations.

    (a) Fuel economy and CO2 emission values determined for 
each vehicle under Sec.  600.114 and as approved in

[[Page 924]]

Sec.  600.008(c), are used to determine vehicle-specific 5-cycle city 
and highway fuel economy and CO2 emission values for each 
vehicle configuration for which data are available.
    (1) If only one set of 5-cycle city and highway fuel economy and 
CO2 emission values is accepted for a vehicle configuration, 
these values, where fuel economy is rounded to the nearest 0.0001 of a 
mile per gallon and the CO2 emission value in grams per mile 
is rounded to the nearest tenth of a gram per mile, comprise the city 
and highway fuel economy and CO2 emission values for that 
configuration.
    (2) If more than one set of 5-cycle city and highway fuel economy 
and CO2 emission values are accepted for a vehicle 
configuration:
    (i) All data shall be grouped according to the subconfiguration for 
which the data were generated using sales projections supplied in 
accordance with Sec.  600.209-12(a)(3).
    (ii) Within each subconfiguration of data, all fuel economy values 
are harmonically averaged and rounded to the nearest 0.0001 of a mile 
per gallon in order to determine 5-cycle city and highway fuel economy 
values for each subconfiguration at which the vehicle configuration was 
tested, and all CO2 emissions values are arithmetically 
averaged and rounded to the nearest tenth of gram per mile to determine 
5-cycle city and highway CO2 emission values for each 
subconfiguration at which the vehicle configuration was tested.
    (iii) All 5-cycle city fuel economy values and all 5-cycle highway 
fuel economy values calculated in paragraph (a)(2)(ii) of this section 
are (separately for city and highway) averaged in proportion to the 
sales fraction (rounded to the nearest 0.0001) within the vehicle 
configuration (as provided to the Administrator by the manufacturer) of 
vehicles of each tested subconfiguration. The resultant values, rounded 
to the nearest 0.0001 mile per gallon, are the 5-cycle city and 5-cycle 
highway fuel economy values for the vehicle configuration.
    (iv) All 5-cycle city CO2 emission values and all 5-cycle 
highway CO2 emission values calculated in paragraph 
(a)(2)(ii) of this section are (separately for city and highway) 
averaged in proportion to the sales fraction (rounded to the nearest 
0.0001) within the vehicle configuration (as provided to the 
Administrator by the manufacturer) of vehicles of each tested 
subconfiguration. The resultant values, rounded to the nearest 0.1 grams 
per mile, are the 5-cycle city and 5-cycle highway CO2 
emission values for the vehicle configuration.
    (3) [Reserved]
    (4) For alcohol dual fuel automobiles and natural gas dual fuel 
automobiles the procedures of paragraphs (a)(1) and (2) of this section 
shall be used to calculate two separate sets of 5-cycle city and highway 
fuel economy and CO2 emission values for each configuration.
    (i) Calculate the 5-cycle city and highway fuel economy and 
CO2 emission values from the tests performed using gasoline 
or diesel test fuel.
    (ii) Calculate the 5-cycle city and highway fuel economy and 
CO2 emission values from the tests performed using alcohol or 
natural gas test fuel, if 5-cycle testing has been performed. Otherwise, 
the procedure in Sec.  600.210-12(a)(3) or (b)(3) applies.
    (b) If only one equivalent petroleum-based fuel economy value exists 
for an electric configuration, that value, rounded to the nearest tenth 
of a mile per gallon, will comprise the petroleum-based 5-cycle fuel 
economy for that configuration.
    (c) If more than one equivalent petroleum-based 5-cycle fuel economy 
value exists for an electric vehicle configuration, all values for that 
vehicle configuration are harmonically averaged and rounded to the 
nearest 0.0001 mile per gallon for that configuration.

Sec.  600.208-12  Calculation of FTP-based and HFET-based fuel economy, 
CO2 emissions, and carbon-related exhaust emissions for a model type.

    (a) Fuel economy, CO2 emissions, and carbon-related 
exhaust emissions for a base level are calculated from vehicle 
configuration fuel economy, CO2 emissions, and carbon-related 
exhaust emissions as determined in Sec.  600.206-12(a), (b), or (c) as 
applicable, for low-altitude tests.

[[Page 925]]

    (1) If the Administrator determines that automobiles intended for 
sale in the State of California and in section 177 states are likely to 
exhibit significant differences in fuel economy, CO2 
emissions, and carbon-related exhaust emissions from those intended for 
sale in other states, she will calculate fuel economy, CO2 
emissions, and carbon-related exhaust emissions for each base level for 
vehicles intended for sale in California and in section 177 states and 
for each base level for vehicles intended for sale in the rest of the 
states.
    (2) In order to highlight the fuel efficiency, CO2 
emissions, and carbon-related exhaust emissions of certain designs 
otherwise included within a model type, a manufacturer may wish to 
subdivide a model type into one or more additional model types. This is 
accomplished by separating subconfigurations from an existing base level 
and placing them into a new base level. The new base level is identical 
to the existing base level except that it shall be considered, for the 
purposes of this paragraph, as containing a new basic engine. The 
manufacturer will be permitted to designate such new basic engines and 
base level(s) if:
    (i) Each additional model type resulting from division of another 
model type has a unique car line name and that name appears on the label 
and on the vehicle bearing that label;
    (ii) The subconfigurations included in the new base levels are not 
included in any other base level which differs only by basic engine 
(i.e., they are not included in the calculation of the original base 
level fuel economy values); and
    (iii) All subconfigurations within the new base level are 
represented by test data in accordance with Sec.  600.010(c)(1)(iii).
    (3) The manufacturer shall supply total model year sales projections 
for each car line/vehicle subconfiguration combination.
    (i) Sales projections must be supplied separately for each car line-
vehicle subconfiguration intended for sale in California and each car 
line/vehicle subconfiguration intended for sale in the rest of the 
states if required by the Administrator under paragraph (a)(1) of this 
section.
    (ii) Manufacturers shall update sales projections at the time any 
model type value is calculated for a label value.
    (iii) The provisions of paragraph (a)(3) of this section may be 
satisfied by providing an amended application for certification, as 
described in Sec.  86.1844 of this chapter.

and carbon-related exhaust emissions, as determined in Sec.  600.206-
12(a), (b) or (c), as applicable, are grouped according to base level.
    (i) If only one vehicle configuration within a base level has been 
tested, the fuel economy, CO2 emissions, and carbon-related 
exhaust emissions from that vehicle configuration will constitute the 
fuel economy, CO2 emissions, and carbon-related exhaust 
emissions for that base level.
    (ii) If more than one vehicle configuration within a base level has 
been tested, the vehicle configuration fuel economy values are 
harmonically averaged in proportion to the respective sales fraction 
(rounded to the nearest 0.0001) of each vehicle configuration and the 
resultant fuel economy value rounded to the nearest 0.0001 mile per 
gallon; and the vehicle configuration CO2 emissions and 
carbon-related exhaust emissions are arithmetically averaged in 
proportion to the respective sales fraction (rounded to the nearest 
0.0001) of each vehicle configuration and the resultant carbon-related 
exhaust emission value rounded to the nearest tenth of a gram per mile.
    (5) The procedure specified in paragraph (a)(1) through (4) of this 
section will be repeated for each base level, thus establishing city, 
highway, and combined fuel economy, CO2 emissions, and 
carbon-related exhaust emissions for each base level.
    (6) [Reserved]
    (7) For alcohol dual fuel automobiles and natural gas dual fuel 
automobiles, the procedures of paragraphs (a)(1) through (6) of this 
section shall be used to calculate two separate sets of city, highway, 
and combined fuel economy, CO2 emissions, and carbon-related 
exhaust emissions for each base level.

    (b) For each model type, as determined by the Administrator, a city, 
highway, and combined fuel economy value, CO2 emission value, 
and a carbon-related exhaust emission value will be calculated by using 
the projected sales and values for fuel economy, CO2 
emissions, and carbon-related exhaust emissions for each base level 
within the model type. Separate model type calculations will be done 
based on the vehicle configuration fuel economy, CO2 
emissions, and carbon-related exhaust emissions as determined in Sec.  
600.206-12(a), (b) or (c), as applicable.
    (1) If the Administrator determines that automobiles intended for 
sale in the State of California and in section 177 states are likely to 
exhibit significant differences in fuel economy, CO2 
emissions, and carbon-related exhaust emissions from those intended for 
sale in other states, he or she will calculate values for fuel economy, 
CO2 emissions, and carbon-related exhaust emissions for each 
model type for vehicles intended for sale in California and in section 
177 states and for each model type for vehicles intended for sale in the 
rest of the states.
    (2) The sales fraction for each base level is calculated by dividing 
the projected sales of the base level within the model type by the 
projected sales of the model type and rounding the quotient to the 
nearest 0.0001.
    (3)(i) The FTP-based city fuel economy values of the model type 
(calculated to the nearest 0.0001 mpg) are determined by dividing one by 
a sum of terms, each of which corresponds to a base level and which is a 
fraction determined by dividing:
    (A) The sales fraction of a base level; by
    (B) The FTP-based city fuel economy value for the respective base 
level.
    (ii) The FTP-based city carbon-related exhaust emission value of the 
model type (calculated to the nearest gram per mile) are determined by a 
sum of terms, each of which corresponds to a base level and which is a 
product determined by multiplying:
    (A) The sales fraction of a base level; by
    (B) The FTP-based city carbon-related exhaust emission value for the 
respective base level.
    (iii) The FTP-based city CO2 emissions of the model type 
(calculated to the nearest gram per mile) are determined by a sum of 
terms, each of which corresponds to a base level and which is a product 
determined by multiplying:
    (A) The sales fraction of a base level; by
    (B) The FTP-based city CO2 emissions for the respective 
base level.
    (4) The procedure specified in paragraph (b)(3) of this section is

Sec.  600.209-12  Calculation of vehicle-specific 5-cycle fuel economy 
and CO2 emission values for a model type.

    (a) Base level. 5-cycle fuel economy and CO2 emission 
values for a base level are calculated from vehicle configuration 5-
cycle fuel economy and CO2 emission values as determined in 
Sec.  600.207 for low-altitude tests.
    (1) If the Administrator determines that automobiles intended for 
sale in

[[Page 927]]

the State of California are likely to exhibit significant differences in 
fuel economy and CO2 emissions from those intended for sale 
in other states, he will calculate fuel economy and CO2 
emission values for each base level for vehicles intended for sale in 
California and for each base level for vehicles intended for sale in the 
rest of the states.
    (2) In order to highlight the fuel efficiency and CO2 
emissions of certain designs otherwise included within a model type, a 
manufacturer may wish to subdivide a model type into one or more 
additional model types. This is accomplished by separating 
subconfigurations from an existing base level and placing them into a 
new base level. The new base level is identical to the existing base 
level except that it shall be considered, for the purposes of this 
paragraph, as containing a new basic engine. The manufacturer will be 
permitted to designate such new basic engines and base level(s) if:
    (i) Each additional model type resulting from division of another 
model type has a unique car line name and that name appears on the label 
and on the vehicle bearing that label;
    (ii) The subconfigurations included in the new base levels are not 
included in any other base level which differs only by basic engine 
(i.e., they are not included in the calculation of the original base 
level fuel economy values); and
    (iii) All subconfigurations within the new base level are 
represented by test data in accordance with Sec.  600.010(c)(i)(ii).
    (3) The manufacturer shall supply total model year sales projections 
for each car line/vehicle subconfiguration combination.
    (i) Sales projections must be supplied separately for each car line-
vehicle subconfiguration intended for sale in California and each car 
line/vehicle subconfiguration intended for sale in the rest of the 
states if required by the Administrator under paragraph (a)(1) of this 
section.
    (ii) Manufacturers shall update sales projections at the time any 
model type value is calculated for a label value.
    (iii) The provisions of this paragraph (a)(3) may be satisfied by 
providing an amended application for certification, as described in 
Sec.  86.1844 of this chapter.
    (4) 5-cycle vehicle configuration fuel economy and CO2 
emission values, as determined in Sec.  600.207-12(a), (b), or (c), as 
applicable, are grouped according to base level.
    (i) If only one vehicle configuration within a base level has been 
tested, the fuel economy and CO2 emission values from that 
vehicle configuration constitute the fuel economy and CO2 
emission values for that base level.
    (ii) If more than one vehicle configuration within a base level has 
been tested, the vehicle configuration fuel economy values are 
harmonically averaged in proportion to the respective sales fraction 
(rounded to the nearest 0.0001) of each vehicle configuration and the 
resultant fuel economy value rounded to the nearest 0.0001 mile per 
gallon.
    (iii) If more than one vehicle configuration within a base level has 
been tested, the vehicle configuration CO2 emission values 
are arithmetically averaged in proportion to the respective sales 
fraction (rounded to the nearest 0.0001) of each vehicle configuration 
and the resultant CO2 emission value rounded to the nearest 
0.1 gram per mile.
    (5) The procedure specified in Sec.  600.209-12(a) will be repeated 
for each base level, thus establishing city and highway fuel economy and 
CO2 emission values for each base level.
    (6) [Reserved]
    (7) For alcohol dual fuel automobiles and natural gas dual fuel 
automobiles, the procedures of paragraphs (a)(1) through (6) of this 
section shall be used to calculate two separate sets of city, highway, 
and combined fuel economy and CO2 emission values for each 
base level.
    (i) Calculate the city and highway fuel economy and CO2 
emission values from the tests performed using gasoline or diesel test 
fuel.
    (ii) If 5-cycle testing was performed on the alcohol or natural gas 
test fuel, calculate the city and highway fuel economy and 
CO2 emission values from the tests performed using alcohol or 
natural gas test fuel.
    (b) Model type. For each model type, as determined by the 
Administrator,

[[Page 928]]

city and highway fuel economy and CO2 emissions values will 
be calculated by using the projected sales and fuel economy and 
CO2 emission values for each base level within the model 
type. Separate model type calculations will be done based on the vehicle 
configuration fuel economy and CO2 emission values as 
determined in Sec.  600.207, as applicable.
    (1) If the Administrator determines that automobiles intended for 
sale in the State of California are likely to exhibit significant 
differences in fuel economy and CO2 emissions from those 
intended for sale in other states, he will calculate fuel economy and 
CO2 emission values for each model type for vehicles intended 
for sale in California and for each model type for vehicles intended for 
sale in the rest of the states.
    (2) The sales fraction for each base level is calculated by dividing 
the projected sales of the base level within the model type by the 
projected sales of the model type and rounding the quotient to the 
nearest 0.0001.
    (3)(i) The 5-cycle city fuel economy values of the model type 
(calculated to the nearest 0.0001 mpg) are determined by dividing one by 
a sum of terms, each of which corresponds to a base level and which is a 
fraction determined by dividing:
    (A) The sales fraction of a base level; by
    (B) The 5-cycle city fuel economy value for the respective base 
level.
    (ii) The 5-cycle city CO2 emissions of the model type 
(calculated to the nearest tenth of a gram per mile) are determined by a 
sum of terms, each of which corresponds to a base level and which is a 
product determined by multiplying:
    (A) The sales fraction of a base level; by
    (B) The 5-cycle city CO2 emissions for the respective 
base level.
    (4) The procedure specified in paragraph (b)(3) of this section is 
repeated in an analogous manner to determine the highway and combined 
fuel economy and CO2 emission values for the model type.
    (5) For alcohol dual fuel automobiles and natural gas dual fuel 
automobiles the procedures of paragraphs (b)(1) through (4) of this 
section shall be used to calculate two separate sets of city and highway 
fuel economy and CO2 emission values for each model type.
    (i) Calculate the city and highway fuel economy and CO2 
emission values from the tests performed using gasoline or diesel test 
fuel.
    (ii) Calculate the city, highway, and combined fuel economy and 
CO2 emission values from the tests performed using alcohol or 
natural gas test fuel, if 5-cycle testing was performed on the alcohol 
or natural gas test fuel. Otherwise, the procedure in Sec.  600.210-
12(a)(3) or (b)(3) applies.

[76 FR 39553, July 6, 2011]



Sec.  600.210-12  Calculation of fuel economy and CO2 emission values 
for labeling.

    (a) General labels. Except as specified in paragraphs (d) and (e) of 
this section, fuel economy and CO2 emissions for general 
labels may be determined by one of two methods. The first is based on 
vehicle-specific model-type 5-cycle data as determined in Sec.  600.209-
12(b). This method is available for all vehicles and is required for 
vehicles that do not qualify for the second method as described in Sec.  
600.115 (other than electric vehicles). The second method, the derived 
5-cycle method, determines fuel economy and CO2 emissions 
values from the FTP and HFET tests using equations that are derived from 
vehicle-specific 5-cycle model type data, as determined in paragraph 
(a)(2) of this section. Manufacturers may voluntarily lower fuel economy 
(MPG) values and raise CO2 values if they determine that the 
label values from any method are not representative of the in-use fuel 
economy and CO2 emissions for that model type, but only if 
the manufacturer changes both the MPG values and the CO2 
value and revises any other affected label value accordingly for a model 
type (including but not limited to the fuel economy 1-10 rating, 
greenhouse gas 1-10 rating, annual fuel cost, 5-year fuel cost 
information). Similarly, for any electric vehicles and plug-in hybrid 
electric vehicles, manufacturers may voluntarily lower the fuel economy 
(MPGe) and raise the energy consumption (kW-hr/100 mile) values if they 
determine that the label values are not representative

[[Page 929]]

of the in-use fuel economy, energy consumption, and CO2 
emissions for that model type, but only if the manufacturer changes both 
the MPGe and the energy consumption value and revises any other affected 
label value accordingly for a model type. Manufacturers may voluntarily 
lower the value for electric driving range if they determine that the 
label values are not representative of the in-use electric driving 
range.
    (1) Vehicle-specific 5-cycle labels. The city and highway model type 
fuel economy determined in Sec.  600.209-12(b), rounded to the nearest 
mpg, and the city and highway model type CO2 emissions 
determined in Sec.  600.209-12(b), rounded to the nearest gram per mile, 
comprise the fuel economy and CO2 emission values for general 
fuel economy labels, or, alternatively;
    (2) Derived 5-cycle labels. Derived 5-cycle city and highway label 
values are determined according to the following method:
    (i)(A) For each model type, determine the derived five-cycle city 
fuel economy using the following equation and coefficients determined by 
the Administrator:
[GRAPHIC] [TIFF OMITTED] TR06JY11.036

Where:

City Intercept = Intercept determined by the Administrator based on 
          historic vehicle-specific 5-cycle city fuel economy data.
City Slope = Slope determined by the Administrator based on historic 
          vehicle-specific 5-cycle city fuel economy data.
MT FTP FE = the model type FTP-based city fuel economy determined under 
          Sec.  600.208-12(b), rounded to the nearest 0.0001 mpg.

    (B) For each model type, determine the derived five-cycle city 
CO2 emissions using the following equation and coefficients 
determined by the Administrator:

Derived 5-cycle City CO2 = ({City Intercept{time}  x A) + 
({City Slope{time}  x MT FTP CO2)

Where:
A = 8,887 for gasoline-fueled vehicles, 10,180 for diesel-fueled 
          vehicles, or an appropriate value specified by the 
          Administrator for other fuels.
City Intercept = Intercept determined by the Administrator based on 
          historic vehicle-specific 5-cycle city fuel economy data.
City Slope = Slope determined by the Administrator based on historic 
          vehicle-specific 5-cycle city fuel economy data.
MT FTP CO2 = the model type FTP-based city CO2 
          emissions determined under Sec.  600.208-12(b), rounded to the 
          nearest 0.1 grams per mile.

    (ii)(A) For each model type, determine the derived five-cycle 
highway fuel economy using the equation below and coefficients 
determined by the Administrator:
[GRAPHIC] [TIFF OMITTED] TR06JY11.037

Where:

Highway Intercept = Intercept determined by the Administrator based on 
          historic vehicle-specific 5-cycle highway fuel economy data.
Highway Slope = Slope determined by the Administrator based on historic 
          vehicle-specific 5-cycle highway fuel economy data.
MT HFET FE = the model type highway fuel economy determined under Sec.  
          600.208-12(b), rounded to the nearest 0.0001 mpg.


[[Page 930]]


    (B) For each model type, determine the derived five-cycle highway 
CO2 emissions using the equation below and coefficients 
determined by the Administrator:

Derived 5-cycle Highway CO2 = ({Highway Intercept{time}  x A) 
+ ({Highway Slope{time}  x MT HFET CO2)

Where:

A = 8,887 for gasoline-fueled vehicles, 10,180 for diesel-fueled 
          vehicles, or an appropriate value specified by the 
          Administrator for other fuels.
Highway Intercept = Intercept determined by the Administrator based on 
          historic vehicle-specific 5-cycle highway fuel economy data.
Highway Slope = Slope determined by the Administrator based on historic 
          vehicle-specific 5-cycle highway fuel economy data.
MT HFET CO2 = the model type highway CO2 emissions 
          determined under Sec.  600.208-12(b), rounded to the nearest 
          0.1 grams per mile.

    (iii) Unless and until superseded by written guidance from the 
Administrator, the following intercepts and slopes shall be used in the 
equations in paragraphs (a)(2)(i) and (ii) of this section:
City Intercept = 0.004091.
City Slope = 1.1601.
Highway Intercept = 0.003191.
Highway Slope = 1.2945.
    (iv) The Administrator will periodically update the slopes and 
intercepts through guidance and will determine the model year that the 
new coefficients must take effect. The Administrator will issue guidance 
no later than six months prior to the earliest starting date of the 
effective model year (e.g., for 2011 models, the earliest start of the 
model year is January 2, 2010, so guidance would be issued by July 1, 
2009.) Until otherwise instructed by written guidance from the 
Administrator, manufacturers must use the coefficients that are 
currently in effect.
    (3) General alternate fuel economy and CO2 emissions 
label values for dual fuel vehicles. (i)(A) City and Highway fuel 
economy label values for dual fuel alcohol-based and natural gas 
vehicles when using the alternate fuel are separately determined by the 
following calculation:
[GRAPHIC] [TIFF OMITTED] TR06JY11.038

Where:

FEalt = The unrounded FTP-based model-type city or HFET-based 
          model-type highway fuel economy from the alternate fuel, as 
          determined in Sec.  600.208-12(b)(5)(ii).
5cycle FEgas = The unrounded vehicle-specific or derived 5-
          cycle model-type city or highway fuel economy, as determined 
          in paragraph (a)(1) or (2) of this section.
FEgas = The unrounded FTP-based city or HFET-based model type 
          highway fuel economy from gasoline (or diesel), as determined 
          in Sec.  600.208-12(b)(5)(i).

    The result, rounded to the nearest whole number, is the alternate 
fuel label value for dual fuel vehicles.
    (B) City and Highway CO2 label values for dual fuel 
alcohol-based and natural gas vehicles when using the alternate fuel are 
separately determined by the following calculation:
[GRAPHIC] [TIFF OMITTED] TR06JY11.039

Where:

CO2alt = The unrounded FTP-based model-type city or HFET-
          based model-type CO2 emissions value from the 
          alternate fuel, as determined in Sec.  600.208-12(b)(5)(ii).
5cycle CO2gas = The unrounded vehicle-specific or derived 5-
          cycle model-type city or highway CO2 emissions 
          value, as determined in paragraph (a)(1) or (2) of this 
          section.
CO2gas = The unrounded FTP-based city or HFET-based model 
          type highway CO2 emissions value from gasoline (or 
          diesel), as determined in Sec.  600.208-12(b)(5)(i).

    The result, rounded to the nearest whole number, is the alternate 
fuel CO2 emissions label value for dual fuel vehicles.

    (ii) Optionally, if complete 5-cycle testing has been performed 
using the alternate fuel, the manufacturer may

[[Page 931]]

choose to use the alternate fuel label city or highway fuel economy and 
CO2 emission values determined in Sec.  600.209-12(b)(5)(ii), 
rounded to the nearest whole number.
    (4) General alternate fuel economy and CO2 emissions 
label values for electric vehicles. Determine FTP-based city and HFET-
based highway fuel economy label values for electric vehicles as 
described in Sec.  600.116. Convert W-hour/mile results to miles per kW-
hr and miles per gasoline gallon equivalent. CO2 label 
information is based on tailpipe emissions only, so CO2 
emissions from electric vehicles are assumed to be zero.
    (5) General alternate fuel economy and CO2 emissions 
label values for fuel cell vehicles. Determine FTP-based city and HFET-
based highway fuel economy label values for fuel cell vehicles using 
procedures specified by the Administrator. Convert kilograms of 
hydrogen/mile results to miles per kilogram of hydrogen and miles per 
gasoline gallon equivalent. CO2 label information is based on 
tailpipe emissions only, so CO2 emissions from fuel cell 
vehicles are assumed to be zero.
    (b) Specific labels. Except as specified in paragraphs (d) and (e) 
of this section, fuel economy and CO2 emissions for specific 
labels may be determined by one of two methods. The first is based on 
vehicle-specific configuration 5-cycle data as determined in Sec.  
600.207. This method is available for all vehicles and is required for 
vehicles that do not qualify for the second method as described in Sec.  
600.115 (other than electric vehicles). The second method, the derived 
5-cycle method, determines fuel economy and CO2 emissions 
values from the FTP and HFET tests using equations that are derived from 
vehicle-specific 5-cycle configuration data, as determined in paragraph 
(b)(2) of this section. Manufacturers may voluntarily lower fuel economy 
values and raise CO2 values if they determine that the label 
values from either method are not representative of the fuel economy or 
CO2 emissions for that model type.
    (1) Vehicle-specific 5-cycle labels. The city and highway 
configuration fuel economy determined in Sec.  600.207, rounded to the 
nearest mpg, and the city and highway configuration CO2 
emissions determined in Sec.  600.207, rounded to the nearest gram per 
mile, comprise the fuel economy and CO2 emission values for 
specific fuel economy labels, or, alternatively;

          historic vehicle-specific 5-cycle highway fuel economy data.
Highway Slope = Slope determined by the Administrator based on historic 
          vehicle-specific 5-cycle highway fuel economy data.

          configuration highway fuel economy from gasoline, as 
          determined in Sec.  600.206.
    The result, rounded to the nearest whole number, is the alternate 
fuel label value for dual fuel vehicles.

    (B) Specific city and highway CO2 emission label values 
for dual fuel alcohol-based and natural gas vehicles when using the 
alternate fuel are separately determined by the following calculation:

[GRAPHIC] [TIFF OMITTED] TR06JY11.043

Where:

CO2alt = The unrounded FTP-based configuration city or HFET-
          based configuration highway CO2 emissions value 
          from the alternate fuel, as determined in Sec.  600.206.
5cycle CO2gas = The unrounded vehicle-specific or derived 5-
          cycle configuration city or highway CO2 emissions 
          value as determined in paragraph (b)(1) or (b)(2) of this 
          section.
CO2gas = The unrounded FTP-based city or HFET-based 
          configuration highway CO2 emissions value from 
          gasoline, as determined in Sec.  600.206.

    The result, rounded to the nearest whole number, is the alternate 
fuel CO2 emissions label value for dual fuel vehicles.

    (ii) Optionally, if complete 5-cycle testing has been performed 
using the alternate fuel, the manufacturer may choose to use the 
alternate fuel label city or highway fuel economy and CO2 
emission values determined in Sec.  600.207-12(a)(4)(ii), rounded to the 
nearest whole number.
    (4) Specific alternate fuel economy and CO2 emissions 
label values for electric vehicles. Determine FTP-based city and HFET-
based highway fuel economy label values for electric vehicles as 
described in Sec.  600.116. Determine these values by running the 
appropriate repeat test cycles. Convert W-hour/mile results to miles per 
kW-hr and miles per gasoline gallon equivalent. CO2 label 
information is based on tailpipe emissions only, so CO2 
emissions from electric vehicles are assumed to be zero.
    (5) Specific alternate fuel economy and CO2 emissions 
label values for fuel cell vehicles. Determine FTP-based city and HFET-
based highway fuel economy label values for fuel cell vehicles using 
procedures specified by the Administrator. Convert kilograms of 
hydrogen/mile results to miles per kilogram of hydrogen and miles per 
gasoline gallon equivalent. CO2 label information is based on 
tailpipe emissions only, so CO2 emissions from fuel cell 
vehicles are assumed to be zero.
    (c) Calculating combined fuel economy. (1) For the purposes of 
calculating the combined fuel economy for a model type, to be used in 
displaying on the label and for determining annual fuel costs under 
subpart D of this part, the manufacturer shall use one of the following 
procedures:
    (i) For gasoline-fueled, diesel-fueled, alcohol-fueled, and natural 
gas-fueled automobiles, and for dual fuel automobiles that can operate 
on gasoline or diesel fuel, harmonically average the unrounded city and 
highway fuel economy values, determined in paragraphs (a)(1) or (2) of 
this section and (b)(1) or (2) of this section, weighted 0.55 and 0.45 
respectively. Round the result to the nearest whole mpg. (An example of 
this calculation procedure appears in Appendix II of this part).
    (ii) For alcohol dual fuel and natural gas dual fuel automobiles 
operated on the alternate fuel, harmonically average the unrounded city 
and highway values from the tests performed using the alternative fuel 
as determined in paragraphs (a)(3) and (b)(3) of this section, weighted 
0.55 and 0.45 respectively. Round the result to the nearest whole mpg.
    (iii) For electric vehicles, calculate the combined fuel economy, in 
miles per kW-hr and miles per gasoline gallon equivalent, by 
harmonically averaging the unrounded city and highway values, weighted 
0.55 and 0.45 respectively. Round miles per kW-hr to the nearest 0.001 
and round miles per gasoline gallon equivalent to the nearest whole 
number.
    (iv) For plug-in hybrid electric vehicles, calculate a combined fuel 
economy value, in miles per gasoline gallon equivalent as follows:

[[Page 934]]

    (A) Determine city and highway fuel economy values for vehicle 
operation after the battery has been fully discharged (``gas only 
operation'' or ``charge-sustaining mode'') as described in paragraphs 
(a) and (b) of this section.
    (B) Determine city and highway fuel economy values for vehicle 
operation starting with a full battery charge (``all-electric 
operation'' or ``gas plus electric operation'', as appropriate, or 
``charge-depleting mode'') as described in Sec.  600.116. For battery 
energy, convert W-hour/mile results to miles per gasoline gallon 
equivalent or miles per diesel gallon equivalent, as applicable. Note 
that you must also express battery-based fuel economy values in miles 
per kW-hr for calculating annual fuel cost as described in Sec.  
600.311.
    (C) Calculate a composite city fuel economy value and a composite 
highway fuel economy value by combining the separate results for battery 
and engine operation using the procedures described in Sec.  600.116). 
Apply the derived 5-cycle adjustment to these composite values. Use 
these values to calculate the vehicle's combined fuel economy as 
described in paragraph (c)(1)(i) of this section.
    (v) For fuel cell vehicles, calculate the combined fuel economy, in 
miles per kilogram and miles per gasoline gallon equivalent, by 
harmonically averaging the unrounded city and highway values, weighted 
0.55 and 0.45 respectively. Round miles per kilogram to the nearest 
whole number and round miles per gasoline gallon equivalent to the 
nearest whole number.
    (2) For the purposes of calculating the combined CO2 
emissions value for a model type, to be used in displaying on the label 
under subpart D of this part, the manufacturer shall:
    (i) For gasoline-fueled, diesel-fueled, alcohol-fueled, and natural 
gas-fueled automobiles, and for dual fuel automobiles that can operate 
on gasoline or diesel fuel, arithmetically average the unrounded city 
and highway values, determined in paragraphs (a)(1) or (2) of this 
section and (b)(1) or (2) of this section, weighted 0.55 and 0.45 
respectively, and round to the nearest whole gram per mile; or
    (ii) For alcohol dual fuel and natural gas dual fuel automobiles 
operated on the alternate fuel, arithmetically average the unrounded 
city and highway CO2 emission values from the tests performed 
using the alternative fuel as determined in paragraphs (a)(3) and (b)(3) 
of this section, weighted 0.55 and 0.45 respectively, and round to the 
nearest whole gram per mile.
    (iii) CO2 label information is based on tailpipe 
emissions only, so CO2 emissions from electric vehicles and 
fuel cell vehicles are assumed to be zero.
    (iv) For plug-in hybrid electric vehicles, calculate combined 
CO2 emissions as follows:
    (A) Determine city and highway CO2 emission rates for 
vehicle operation after the battery has been fully discharged (``gas 
only operation'' or ``charge-sustaining mode'') as described in 
paragraphs (a) and (b) of this section.
    (B) Determine city and highway CO2 emission rates for 
vehicle operation starting with a full battery charge (``all-electric 
operation'' or ``gas plus electric operation'', as appropriate, or 
``charge-depleting mode'') as described in Sec.  600.116. Note that 
CO2 label information is based on tailpipe emissions only, so 
CO2 emissions from electricity are assumed to be zero.
    (C) Calculate a composite city CO2 emission rate and a 
composite highway CO2 emission rate by combining the separate 
results for battery and engine operation using the procedures described 
in Sec.  600.116. Use these values to calculate the vehicle's combined 
CO2 emissions as described in paragraph (c)(2)(i) of this 
section.
    (d) Calculating combined fuel economy, CO2 emissions, and 
driving range. (1) If the criteria in Sec.  600.115-11(a) are met for a 
model type, both the city and highway fuel economy and CO2 
emissions values must be determined using the vehicle-specific 5-cycle 
method. If the criteria in Sec.  600.115-11(b) are met for a model type, 
the city fuel economy and CO2 emissions values may be 
determined using either method, but the highway fuel economy and 
CO2 emissions values must be determined using the vehicle-
specific 5-cycle method (or modified 5-cycle method as allowed under 
Sec.  600.114-12(b)(2)).

[[Page 935]]

    (2) If the criteria in Sec.  600.115 are not met for a model type, 
the city and highway fuel economy and CO2 emission label 
values must be determined by using the same method, either the derived 
5-cycle or vehicle-specific 5-cycle.
    (3) Manufacturers may use one of the following methods to determine 
5-cycle values for fuel economy, CO2 emissions, and driving 
range for electric vehicles:
    (i) Generate 5-cycle data as described in paragraph (a)(1) of this 
section using the procedures of SAE J1634 (incorporated by reference in 
Sec.  600.011) with amendments and revisions as described in Sec.  
600.116-12(a).
    (ii) Multiply 2-cycle fuel economy values and driving range by 0.7 
and divide 2-cycle CO2 emission values by 0.7.
    (iii) Manufacturers may ask the Administrator to approve adjustment 
factors for deriving 5-cycle fuel economy results from 2-cycle test data 
based on operating data from their in-use vehicles. Such data should be 
collected from multiple vehicles with different drivers over a range of 
representative driving routes and conditions. The Administrator may 
approve such an adjustment factor for any of the manufacturer's vehicle 
models that are properly represented by the collected data.
    (e) Fuel economy values and other information for advanced 
technology vehicles. (1) The Administrator may prescribe an alternative 
method of determining the city and highway model type fuel economy and 
CO2 emission values for general, unique or specific fuel 
economy labels other than those set forth in this subpart C for advanced 
technology vehicles including, but not limited to fuel cell vehicles, 
hybrid electric vehicles using hydraulic energy storage, and vehicles 
equipped with hydrogen internal combustion engines.
    (2) For advanced technology vehicles, the Administrator may 
prescribe special methods for determining information other than fuel 
economy that is required to be displayed on fuel economy labels as 
specified in Sec.  600.302-12(e).
    (f) Sample calculations. An example of the calculation required in 
this subpart is in Appendix III of this part.

maintained on each automobile:
    (1) A general fuel economy label (initial, or updated as required in 
Sec.  600.314) as described in Sec.  600.302 or:
    (2) A specific label, for those automobiles manufactured or imported 
before the date that occurs 15 days after general labels have been 
determined by the manufacturer, as described in Sec.  600.210-08(b) or 
Sec.  600.210-12(b).
    (i) If the manufacturer elects to use a specific label within a 
model type (as defined in Sec.  600.002, he shall also affix specific 
labels on all automobiles within this model type, except on those 
automobiles manufactured or imported before the date that labels are 
required to bear range values as required by paragraph (b) of this 
section, or determined by the Administrator, or as permitted under Sec.  
600.310.
    (ii) If a manufacturer elects to change from general to specific 
labels or vice versa within a model type, the manufacturer shall, within 
five calendar days, initiate or discontinue as applicable, the use of 
specific labels on all vehicles within a model type at all facilities 
where labels are affixed.
    (3) For any vehicle for which a specific label is requested which 
has a combined FTP/HFET-based fuel economy value, as determined in Sec.  
600.513, at or below the minimum tax-free value, the following statement 
must appear on the specific label:
    ``[Manufacturer's name] may have to pay IRS a Gas Guzzler Tax on 
this vehicle because of the low fuel economy.''

[[Page 936]]

    (4)(i) At the time a general fuel economy value is determined for a 
model type, a manufacturer shall, except as provided in paragraph 
(a)(4)(ii) of this section, relabel, or cause to be relabeled, vehicles 
which:
    (A) Have not been delivered to the ultimate purchaser, and
    (B) Have a combined FTP/HFET-based model type fuel economy value (as 
determined in Sec.  600.208-08(b) or Sec.  600.208-12(b) of 0.1 mpg or 
more below the lowest fuel economy value at which a Gas Guzzler Tax of 
$0 is to be assessed.
    (ii) The manufacturer has the option of re-labeling vehicles during 
the first five working days after the general label value is known.
    (iii) For those vehicle model types which have been issued a 
specific label and are subsequently found to have tax liability, the 
manufacturer is responsible for the tax liability regardless of whether 
the vehicle has been sold or not or whether the vehicle has been 
relabeled or not.
    (b) The manufacturer shall include the current range of fuel economy 
of comparable automobiles (as described in Sec. Sec.  600.311 and 
600.314) in the label of each vehicle manufactured or imported more than 
15 calendar days after the current range is made available by the 
Administrator.
    (1) Automobiles manufactured or imported before a date 16 or more 
calendar days after the initial label range is made available under 
Sec.  600.311 shall include the range from the previous model year.
    (2) Automobiles manufactured or imported more than 15 calendar days 
after the label range is made available under Sec.  600.311 shall be 
labeled with the current range of fuel economy of comparable automobiles 
as approved for that label.
    (c) The fuel economy label must be readily visible from the exterior 
of the automobile and remain affixed until the time the automobile is 
delivered to the ultimate consumer.
    (1) It is preferable that the fuel economy label information be 
incorporated into the Automobile Information Disclosure Act label, 
provided that the prominence and legibility of the fuel economy label is 
maintained. For this purpose, all fuel economy label information must be 
placed on a separate section in the Automobile Information Disclosure 
Act label and may not be intermixed with that label information, except 
for vehicle descriptions as noted in Sec.  600.303-08(d)(1).
    (2) The fuel economy label must be located on a side window. If the 
window is not large enough to contain both the Automobile Information 
Disclosure Act label and the fuel economy label, the manufacturer shall 
have the fuel economy label affixed on another window and as close as 
possible to the Automobile Information Disclosure Act label.
    (3) The manufacturer shall have the fuel economy label affixed in 
such a manner that appearance and legibility are maintained until after 
the vehicle is delivered to the ultimate consumer.
    (d) The labeling requirements specified in this subpart for 2008 
model year vehicles continue to apply through the 2011 model year. In 
the 2012 model year, manufacturers may label their vehicles as specified 
in this subpart for either 2008 or 2012 model years. The labeling 
requirements specified in this subpart for 2012 model year vehicles are

SUVs). For x, y, and z, insert the appropriate values established by 
EPA.
    (3) Include one of the following statements in the right side of the 
field:
    (i) For vehicles with calculated fuel costs higher than the average 
vehicle as specified in Sec.  600.311: ``You spend $x more in fuel costs 
over 5 years compared to the average new vehicle.'' Complete the 
statement by including the calculated increase in fuel costs as 
specified in Sec.  600.311.
    (ii) For all other vehicles: ``You save $x in fuel costs over 5 
years compared to the average new vehicle.'' Complete the statement by 
including the calculated fuel savings as specified in Sec.  600.311. 
Note that this includes fuel savings of $0.
    (d) Annual fuel cost. Include the following statement in the field 
in the lower left portion of the label: ``Annual fuel cost $x''. 
Complete this statement using the value for annual fuel cost determined 
in Sec.  600.311.
    (e) Performance ratings. Include the following information in the 
field in the lower left portion of the label:
    (1) The heading, ``Fuel Economy and Greenhouse Gas Rating (tailpipe 
only)'' in the top left corner of the field.
    (2) A slider bar below the heading in the left portion of the field 
to characterize the vehicle's fuel economy and greenhouse gas ratings, 
as determined in Sec.  600.311. Position a box with a downward-pointing 
wedge above the slider bar positioned to show where that vehicle's fuel 
economy rating falls relative to the total range; include the vehicle's 
fuel economy rating inside the box. If the greenhouse gas rating from 
Sec.  600.311 is different than the fuel economy rating, position a 
second box with an upward-pointing wedge below the slider bar positioned 
to show where that vehicle's greenhouse gas rating falls relative to the 
total range; include the vehicle's greenhouse gas rating inside the box. 
Include the expression ``CO2'' to the left of the box with 
the greenhouse gas rating and add the expression MPG to the left of the 
box with the fuel economy rating. Include the number 1 inside the border 
at the left end of the slider bar. Include the number 10 inside the 
border at the right end of the slider bar and add the term ``Best'' 
below the slider bar, directly under the number. EPA will periodically 
calculate and publish updated rating values as described in Sec.  
600.311. Add color to the slider bar such that it is blue at the left 
end of the range, white at the right end of the range, and shaded 
continuously across the range.
    (3) The heading, ``Smog Rating (tailpipe only)'' in the top right 
corner of the field.
    (4) Insert a slider bar in the right portion of the field to 
characterize the vehicle's level of emission control for ozone-related 
air pollutants relative to that of all vehicles. Position a box with a 
downward-pointing wedge above the slider bar positioned to show where 
that vehicle's emission rating falls relative to the total range. 
Include the vehicle's emission rating (as described in Sec.  600.311) 
inside the box. Include the number 1 in the border at the left end of 
the slider bar; include the number 10 in the border at the right end of 
the slider bar and add the term ``Best'' below the slider bar, directly 
under the number. EPA will periodically calculate and publish updated 
range values as described in Sec.  600.311. Add color to the slider bar 
such that it is blue at the left end of the range, white at the right 
end of the range, and shaded continuously across the range.
    (5) The following statements below the slider bars: ``This vehicle 
emits x grams CO2 per mile. The best emits 0

[[Page 939]]

grams per mile (tailpipe only). Producing and distributing fuel also 
create emissions; learn more at fueleconomy.gov.'' For x, insert the 
vehicle's composite CO2 emission rate as described in Sec.  
600.311. See Sec. Sec.  600.308 and 600.310 for specifications that 
apply for vehicles powered by electricity.
    (f) Vehicle description. Where the fuel economy label is physically 
incorporated with the Motor Vehicle Information and Cost Savings Act 
label, no further vehicle description is needed. If the fuel economy 
label is separate from the Automobile Information Disclosure Act label, 
describe the vehicle in a location on the label that does not interfere 
with the other required information. In cases where the vehicle 
description may not easily fit on the label, the manufacturer may 
request Administrator approval of modifications to the label format to 
accommodate this information. Include the following items in the vehicle 
description, if applicable:
    (1) Model year.
    (2) Vehicle car line.
    (3) Engine displacement, in cubic inches, cubic centimeters, or 
liters whichever is consistent with the customary description of that 
engine.
    (4) Transmission class.
    (5) Other descriptive information, as necessary, such as number of 
engine cylinders, to distinguish otherwise identical model types or, in 
the case of specific labels, vehicle configurations, as approved by the 
Administrator.
    (g) [Reserved]
    (h) Gas guzzler provisions. For vehicles requiring a tax statement 
under Sec.  600.513, add the phrase ``$x gas guzzler tax'', where $x is 
the value of the tax. The tax value required by this paragraph (h) is 
based on the combined fuel economy value for the model type calculated 
according to Sec.  600.513 and rounded to the nearest 0.1 mpg.
    (i) Alternative label provisions for special cases. The 
Administrator may approve modifications to the style guidelines if space 
is limited. The Administrator may also prescribe special label format 
and information requirements for vehicles that are not specifically 
described in this subpart, such as hydrogen-fueled internal combustion 
engines or hybrid electric vehicles that have engines operating on fuels 
other than gasoline or diesel fuel. The Administrator may also approve 
alternate wording of statements on the label if that is necessary or 
appropriate for a given fuel or combination of fuels. The revised 
labeling specifications will conform to the principles established in 
this subpart, with any appropriate modifications or additions to reflect 
the vehicle's unique characteristics. See 49 U.S.C. 32908(b)(1)(F).
    (j) Rounding. Unless the regulation specifies otherwise, do not 
round intermediate values, but round final calculated values identified 
in this subpart to the nearest whole number.
    (k) Updating information. EPA will periodically publish updated

Sec.  600.311-12  Determination of values for fuel economy labels.

    (a) Fuel economy. Determine city and highway fuel economy values as 
described in Sec.  600.210-12(a) and (b). Determine combined fuel 
economy values as described in Sec.  600.210-12(c). Note that the label 
for plug-in hybrid electric vehicles requires separate values for 
combined fuel economy for vehicle operation before and after the 
vehicle's battery is fully discharged; we generally refer to these modes 
as ``Blended Electric + Gas'' (or ``Electric Only'', as applicable) and 
``Gas only''.
    (b) CO2 emission rate. Determine the engine-related CO2 
emission rate as described in Sec.  600.210-12(d).
    (c) Fuel consumption rate. Calculate the fuel consumption rate as 
follows:
    (1) For vehicles with engines that are not plug-in hybrid electric 
vehicles, calculate the fuel consumption rate in gallons per 100 miles 
(or gasoline gallon equivalent per 100 miles for fuels other than 
gasoline or diesel fuel) with the following formula, rounded to the 
first decimal place:

Fuel Consumption Rate = 100/MPG

Where:

MPG = The value for combined fuel economy from Sec.  600.210-12(c), 
          rounded to the nearest whole mpg.

    (2) For plug-in hybrid electric vehicles, calculate two separate 
fuel consumption rates as follows:
    (i) Calculate the fuel consumption rate based on engine operation 
after the battery is fully discharged as described in paragraph (c)(1) 
of this section.
    (ii) Calculate the fuel consumption rate during operation before the 
battery is fully discharged in kW-hours per 100 miles as described in 
SAE J1711 (incorporated by reference in Sec.  600.011), as described in 
Sec.  600.116.
    (3) For electric vehicles, calculate the fuel consumption rate in 
kW-hours per 100 miles with the following formula, rounded to the 
nearest whole number:


Fuel Consumption Rate = 100/MPG

Where:

MPG = The combined fuel economy value from paragraph (a) of this 
          section, in miles per kW-hour.

    (4) For hydrogen fuel cell vehicles, calculate the fuel consumption 
rate in kilograms of hydrogen per 100 miles with the following formula, 
rounded to the nearest whole number:


Fuel Consumption Rate = 100/MPG

Where:

MPG = The combined fuel economy value from paragraph (a) of this 
          section, in miles per kilogram of hydrogen.

    (d) Fuel economy and greenhouse gas ratings. Determine a vehicle's 
fuel economy and greenhouse gas ratings as follows:
    (1) For gasoline-fueled vehicles that are not plug-in hybrid 
electric vehicles (including flexible fuel vehicles that operate on 
gasoline), establish a single rating based only on the vehicle's 
combined fuel economy from paragraph (a) of this section. For all other 
vehicles, establish a fuel economy rating based

[[Page 945]]

on the vehicle's combined fuel economy and establish a separate 
greenhouse gas rating based on combined CO2 emission rates 
from paragraph (b) of this section.
    (2) We will establish the fuel economy rating based on fuel 
consumption values specified in paragraph (c) of this section. We will 
establish the value dividing the 5 and 6 ratings based on the fuel 
consumption corresponding to the projected achieved Corporate Average 
Fuel Economy level for the applicable model year. This is intended to 
prevent below-average vehicles from getting an above-average fuel 
economy rating for the label. We will establish the remaining cutpoints 
based on a statistical evaluation of available information from the 
certification database for all model types. Specifically, the mean value 
plus two standard deviations will define the point between the 1 and 2 
ratings. The mean value minus two standard deviations will define the 
point between the 9 and 10 ratings. The 1 rating will apply for any 
vehicle with higher fuel consumption rates than the 2 rating; similarly, 
the 10 rating will apply for any vehicle with lower fuel consumption 
rates than the 9 rating. We will calculate range values for the 
remaining intermediate ratings by dividing the range into equal 
intervals. We will convert the resulting range intervals to equivalent 
miles-per-gallon values. We will define the greenhouse gas ratings by 
converting the values from the fuel economy rating intervals to 
equivalent CO2 emission rates using the conventional 
conversion factor for gasoline (8887 g CO2 per gallon of 
consumed fuel).
    (e) Annual fuel cost. Calculate annual fuel costs as follows:
    (1) Except as specified in paragraph (e)(3) of this section, 
calculate the total annual fuel cost with the following formula, rounded 
to nearest $50:


Annual Fuel Cost = Fuel Price/MPG x Average Annual Miles

Where:

Fuel Price = The estimated fuel price provided by EPA for the type of 
          fuel required for the vehicle. The units are dollars per 
          gallon for gasoline and diesel fuel, dollars per gasoline 
          gallon equivalent for natural gas, dollars per kW-hr for plug-
          in electricity, and dollars per kilogram of hydrogen for 
          hydrogen fuel cell vehicles.
MPG = The combined fuel economy value from paragraph (a) of this 
          section. The units are miles per gallon for gasoline and 
          diesel fuel, miles per gasoline gallon equivalent for natural 
          gas, miles per kW-hr for plug-in electricity, and miles per 
          kilogram of hydrogen for hydrogen fuel cell vehicles.
Average Annual Miles = The estimated annual mileage figure provided by 
          EPA, in miles.

    (2) For dual fuel vehicles and flexible fuel vehicles, disregard 
operation on the alternative fuel.
    (3) For plug-in hybrid electric vehicles, calculate annual fuel cost 
as described in this paragraph (e)(3). This description applies for 
vehicles whose engine starts only after the battery is fully discharged. 
Use good engineering judgment to extrapolate this for calculating annual 
fuel cost for vehicles that use combined power from the battery and the 
engine before the battery is fully discharged. Calculate annual fuel 
cost as follows:
    (i) Determine the charge-depleting ranges for city and highway 
operation as described in paragraph (j)(4)(i) of this section. Adjust 
each of these values for 5-cycle operation.
    (ii) Calculate multi-day individual utility factors (UF) as 
described in Sec.  600.116 corresponding to the driving ranges from 
paragraph (e)(3)(i) of this section.
    (iii) Calculate values for the vehicle's average fuel economy over 
the charge-depleting range (in miles per kW-hr) for city and highway 
operation as described in Sec.  600.210. Adjust each of these values for 
5-cycle operation. Convert these to $/mile values by dividing the 
appropriate fuel price from paragraph (e)(1) of this section by the 
average fuel economy determined in this paragraph (e)(3)(iii).
    (iv) Calculate values for the vehicle's average fuel economy over 
the charge-sustaining range (in miles per gallon) for city and highway 
operation as described in Sec.  600.210-12. Adjust each of these values 
for 5-cycle operation. Convert these to $/mile values by dividing the 
appropriate fuel price from paragraph (e)(1) of this section by the 
average fuel economy determined in this paragraph (e)(3)(iv).

[[Page 946]]

    (v) Calculate a composite $/mile value for city driving using the 
following equation:


$/mile = $/mileCD x UF + $/mileCS x (1-UF)

    (vi) Repeat the calculation in paragraph (e)(3)(v) of this section 
for highway driving.
    (vii) Calculate the annual fuel cost based on the combined values 
for city and highway driving using the following equation:

Annual fuel cost = ($/milecity x 0.55 + $/milehwy x 0.45) x Average 
Annual Miles
    (4) Round the annual fuel cost to the nearest $50 by dividing the 
unrounded annual fuel cost by 50, then rounding the result to the 
nearest whole number, then multiplying this rounded result by 50 to 
determine the annual fuel cost to be used for purposes of labeling.

    (f) Fuel savings. Calculate an estimated five-year cost increment 
relative to an average vehicle by multiplying the annual fuel cost from 
paragraph (e) of this section by 5 and subtracting this value from the 
average five-year fuel cost. We will calculate the average five-year 
fuel cost from the annual fuel cost equation in paragraph (e) of this 
section based on a gasoline-fueled vehicle with a mean fuel economy 
value, consistent with the value dividing the 5 and 6 ratings under 
paragraph (d) of this section. The average five-year fuel cost for model 
year 2012 is $12,600 for a 22-mpg vehicle that drives 15,000 miles per 
year with gasoline priced at $3.70 per gallon. We may periodically 
update this five year reference fuel cost for later model years to 
better characterize the fuel economy for an average vehicle. Round the 
calculated five-year cost increment to the nearest $50. Negative values 
represent a cost increase compared to the average vehicle.
    (g) Smog rating. Establish a rating for exhaust emissions other than 
CO2 based on the applicable emission standards for the 
appropriate model year as shown in Tables 1 through 3 of this section. 
Unless specified otherwise, use the California emission standards to 
select the smog rating only for vehicles not certified to any EPA 
standards. For Independent Commercial Importers that import vehicles not 
subject to Tier 2 or Tier 3 emission standards, the vehicle's smog 
rating is 1. Similarly, if a manufacturer certifies vehicles to emission 
standards that are less stringent than all the identified standards for 
any reason, the vehicle's smog rating is 1. If EPA or California 
emission standards change in the future, we may revise the emission 
levels corresponding to each rating for future model years as 
appropriate to reflect the changed standards. If this occurs, we would 
publish the revised ratings as described in Sec.  600.302-12(k), 
allowing sufficient lead time to make the changes; we would also expect 
to initiate a rulemaking to update the smog rating in the regulation.

    (h) Ranges of fuel economy and CO2 emission values. We 
will determine the range of combined fuel economy and CO2 
emission values for each vehicle class identified in Sec.  600.315. We 
will generally update these range values before the start of each model 
year based on the lowest and highest values within each vehicle class. 
We will also use this same information to establish a range of fuel 
economy values for all vehicles. Continue to use the most recently 
published numbers until we update them, even if you start a new model 
year before we publish the range values for the new model year.
    (i) [Reserved]
    (j) Driving range. Determine the driving range for certain vehicles 
as follows:
    (1) For vehicles operating on nonpressurized liquid fuels, determine 
the vehicle's driving range in miles by multiplying the combined fuel 
economy described in paragraph (a) of this section by the vehicle's 
usable fuel storage capacity, rounded to the nearest whole number.
    (2) For electric vehicles, determine the vehicle's overall driving 
range as described in Section 8 of SAE J1634 (incorporated by reference 
in Sec.  600.011), with amendments and revisions as described in Sec.  
600.116. Determine separate range values for FTP-based city and HFET-
based highway driving. Adjust these values to represent 5-cycle values 
as described in Sec.  600.210-12(d)(3), then combine them arithmetically 
by averaging the two values, weighted 0.55 and 0.45, respectively, and 
rounding to the nearest whole number.
    (3) For natural gas vehicles, determine the vehicle's driving range 
in miles by multiplying the combined fuel economy described in paragraph 
(a) of this section by the vehicle's usable fuel storage capacity 
(expressed in gasoline gallon equivalents), rounded to the nearest whole 
number.
    (4) For plug-in hybrid electric vehicles, determine the adjusted 
charge-depleting (Rcda) driving range, the adjusted all electric driving 
range (if applicable), and overall adjusted driving range as described 
in SAE J1711 (incorporated by reference in Sec.  600.011), as described 
in Sec.  600.116, as follows:
    (i) Determine the vehicle's Actual Charge-Depleting Range, 
Rcda, separately for FTP-based city and HFET-based highway 
driving. Adjust these values to represent 5-cycle values as described in 
600.115-11, then combine

[[Page 948]]

them arithmetically by averaging the two values, weighted 0.55 and 0.45, 
respectively, and rounding to the nearest whole number. Precondition the 
vehicle as needed to minimize engine operation for consuming stored fuel 
vapors in evaporative canisters; for example, you may purge the 
evaporative canister or time a refueling event to avoid engine starting 
related to purging the canister. For vehicles that use combined power 
from the battery and the engine before the battery is fully discharged, 
also use this procedure to establish an all electric range by 
determining the distance the vehicle drives before the engine starts, 
rounded to the nearest mile. You may represent this as a range of 
values. We may approve adjustments to these procedures if they are 
necessary to properly characterize a vehicle's all electric range.
    (ii) Use good engineering judgment to calculate the vehicle's 
operating distance before the fuel tank is empty when starting with a 
full fuel tank and a fully charged battery, consistent with the 
procedure and calculation specified in this paragraph (j), rounded to 
the nearest 10 miles.
    (5) For hydrogen fuel cell vehicles, determine the vehicle's driving 
range in miles by multiplying the combined fuel economy described in 
paragraph (a) of this section by the vehicle's usable fuel storage 
capacity (expressed in kilograms of hydrogen), rounded to the nearest 
whole number.
    (k) Charge time. For electric vehicles, determine the time it takes 
to fully charge the battery from a 240 volt power source to the point 
that the battery meets the manufacturer's end-of-charge criteria, 
consistent with the procedures specified in SAE J1634 (incorporated by 
reference in Sec.  600.011) for electric vehicles and in SAE J1711 
(incorporated by reference in Sec.  600.011) for plug-in hybrid electric 
vehicles, as described in Sec.  600.116. This value may be more or less 
than the 12-hour minimum charging time specified for testing. You must 
alternatively specify the charge time based on a standard 120 volt power 
source if the vehicle cannot be charged at the higher voltage.
    (l) California-specific values. If the Administrator determines that 
automobiles intended for sale in California are likely to exhibit 
significant differences in fuel economy or other label values from those 
intended for sale in other states, the Administrator will compute 
separate values for each class of automobiles for California and for the 
other states.

Sec.  600.312-08  Labeling, reporting, and recordkeeping; 
Administrator reviews.

    (a)(1) The manufacturer shall determine label values (general and 
specific) using the procedures specified in subparts C and D of this 
part and submit the label values, and the data sufficient to calculate 
the label values, to the Administrator according to the timetable 
specified in Sec.  600.313.
    (2) Except under paragraph (a)(4) of this section, the manufacturer 
is not required to obtain Administrator approval of label values prior 
to the introduction of vehicles for sale.
    (3) The label values that the manufacturer calculates and submits 
under paragraph (a)(1) of this section shall constitute the EPA fuel 
economy estimates unless the Administrator determines that they are not 
calculated according to the procedures specified in subparts C and D of 
this part.
    (4) If required by the Administrator, the manufacturer shall obtain 
Administrator approval of label values prior to affixing labels to 
vehicles.
    (5)(i) If at any time during the model year, any label values are 
determined not to be calculated according to the procedures specified in 
subparts C and D of this part, the Administrator shall notify the 
manufacturer in writing.
    (ii) If the Administrator has sufficient information to enable 
calculation of the correct label values, this notification shall specify 
the correct label values which constitute the EPA Fuel Economy 
Estimates.
    (iii) If additional information is required, the Administrator shall 
request such additional information and a recalculation of the label 
value by the manufacturer.
    (6) If the Administrator determines revised label values under 
paragraph

[[Page 949]]

(a)(5) of this section are lower than the label values calculated by the 
manufacturer, the manufacturer shall affix the revised labels to all 
affected new vehicles which are unsold beginning no later than 15 
calendar days after the date of notification by the Administrator.
    (b)(1) The manufacturer is responsible for affixing vehicle labels 
that meet the format and content requirements of this subpart.
    (2) The manufacturer shall retain for examination, at the 
Administrator's discretion, typical label formats representing all 
information required on the manufacturer's fuel economy labels. The 
information shall include the text of all required and voluntary 
information as well as the size and color of print and paper, spacing, 
and location of all printed information. Where the fuel economy label is 
incorporated with the Automobile Information Disclosure Act label, the 
above requirements pertain to those sections of the label concerning 
fuel economy labeling information.
    (3) If the Administrator determines upon examination of record that 
the label format or content do not meet the requirements of this 
subpart, the Administrator may:
    (i) Require the manufacturer to make specific changes in subsequent 
labels, and
    (ii) Require such changes to be implemented on a reasonable 
timetable, but no sooner than 15 days from the date of notification to 
the manufacturer.

Sec.  600.313-08  Timetable for data and information submittal and review.

    (a) A manufacturer shall submit to the Administrator fuel economy 
label values and sufficient information to determine fuel economy label 
values within the following time constraints (except for manufacturers 
designated under Sec.  600.312(a)(4) who shall submit the information no 
later than thirty calendar days prior to the date the model type 
[vehicle] is initially offered for sale.
    (1) For initial general label values, no later than five working 
days before the date that the model type is initially offered for sale;
    (2) For specific label values, no later than five working days 
before any vehicles are offered for sale;
    (3) For model types having label values updated because of running 
changes (as required under Sec.  600.314(b)), the submission must be 
made at least five working days before the date of implementation of the 
running change.
    (b) A manufacturer may not proceed with any label calculation until 
the data from each vehicle used in such calculation satisfies the 
requirements of Sec.  600.008, except as allowed under the provisions of 
Sec.  600.314-01(e) and approved by the Administrator.
    (c) If the Administrator has waived any testing in paragraph (b) of 
this section and subsequently finds that the decision to waive testing 
was based on an incorrect data submission or that a fuel economy offset 
exists (based on subsequent testing of that manufacturer's product 
line), the Administrator may require confirmation of the data generated 
by any such waived vehicle.

Sec.  600.314-08  Updating label values, annual fuel cost, Gas Guzzler Tax, 
and range of fuel economy for comparable automobiles.

    (a) The label values established in Sec.  600.312 shall remain in 
effect for the model year unless updated in accordance with paragraph 
(b) of this section.
    (b)(1) The manufacturer shall recalculate the model type fuel 
economy values for any model type containing base levels affected by 
running changes specified in Sec.  600.507.
    (2) For separate model types created in Sec.  600.209-08(a)(2) or 
Sec.  600.209-12(a)(2), the manufacturer shall recalculate the model 
type values for any additions or deletions of subconfigurations to the 
model type. Minimum data requirements specified in Sec.  600.010(c) 
shall be met prior to recalculation.
    (3) Label value recalculations shall be performed as follows:
    (i) The manufacturer shall use updated total model year projected 
sales for label value recalculations.
    (ii) All model year data approved by the Administrator at the time 
of the

[[Page 950]]

recalculation for that model type shall be included in the 
recalculation.
    (iii) Using the additional data under this paragraph (b), the 
manufacturer shall calculate new model type city and highway values in 
accordance with Sec.  600.210 except that the values shall be rounded to 
the nearest 0.1 mpg.
    (iv) The existing label values, calculated in accordance with Sec.  
600.210, shall be rounded to the nearest 0.1 mpg.
    (4)(i) If the recalculated city or highway fuel economy value in 
paragraph (b)(3)(iii) of this section is less than the respective city 
or highway value in paragraph (b)(3)(iv) of this section by 1.0 mpg or 
more, the manufacturer shall affix labels with the recalculated model 
type values (rounded to the nearest whole mpg) to all new vehicles of 
that model type beginning on the day of implementation of the running 
change.
    (ii) If the recalculated city or highway fuel economy value in 
paragraph (b)(3)(iii) of this section is higher than the respective city 
or highway value in paragraph (b)(3)(iv) of this section by 1.0 mpg or

values for labeling the entire model type beginning on the day of 
implementation of the running change.
    (c) For fuel economy labels updated using recalculated fuel economy 
values determined in accordance with paragraph (b) of this section, the 
manufacturer shall concurrently update all other label information 
(e.g., the annual fuel cost, range of comparable vehicles and the 
applicability of the Gas Guzzler Tax as needed).
    (d) The Administrator shall periodically update the range of fuel 
economies of comparable automobiles based upon all label data supplied 
to the Administrator.
    (e) The manufacturer may request permission from the Administrator 
to calculate and use label values based on test data from vehicles which 
have not completed the Administrator-ordered confirmatory testing 
required under the provisions of Sec.  600.008-08(b). If the 
Administrator approves such a calculation the following procedures shall 
be used to determine if relabeling is required after the confirmatory 
testing is completed.
    (1) The Administrator-ordered confirmatory testing shall be 
completed as quickly as possible.
    (2) Using the additional data under paragraph (e)(1) of this 
section, the manufacturer shall calculate new model type city and 
highway values in accordance with Sec. Sec.  600.207 and 600.210 except 
that the values shall be rounded to the nearest 0.1 mpg.
    (3) The existing label values, calculated in accordance with Sec.  
600.210, shall be rounded to the nearest 0.1 mpg.
    (4) The manufacturer may need to revise fuel economy labels as 
follows:
    (i) If the recalculated city or highway fuel economy value in 
paragraph (b)(3)(iii) of this section is less than the respective city 
or highway value in paragraph (b)(3)(iv) of this section by 0.5 mpg or 
more, the manufacturer shall affix labels with the recalculated model 
type MPG values (rounded to the nearest whole number) to all new 
vehicles of that model type beginning 15 days after the completion of 
the confirmatory test.
    (ii) If both the recalculated city or highway fuel economy value in 
paragraph (b)(3)(iii) of this section is less than the respective city 
or highway value in paragraph (b)(3)(iv) of this section by 0.1 mpg or 
more and the recalculated gas guzzler tax rate determined under the 
provisions of Sec.  600.513-08 is larger, the manufacturer shall affix 
labels with the recalculated model type values and gas guzzler tax 
statement and rates to all new vehicles of that model type beginning 15 
days after the completion of the confirmatory test.
    (5) For fuel economy labels updated using recalculated fuel economy 
values determined in accordance with paragraph (e)(4) of this section, 
the manufacturer shall concurrently update all other label information 
(e.g., the annual fuel cost, range of comparable vehicles and the 
applicability of the Gas Guzzler Tax if required by Department of 
Treasury regulations).

[76 FR 39565, July 6, 2011]



Sec.  600.315-08  Classes of comparable automobiles.

    (a) The Secretary will classify automobiles as passenger automobiles 
or

[[Page 951]]

light trucks (nonpassenger automobiles) in accordance with 49 CFR part 
523.
    (1) The Administrator will classify passenger automobiles by car 
line into one of the following classes based on interior volume index or 
seating capacity except for those passenger automobiles which the 
Administrator determines are most appropriately placed in a different 
classification or classed as special purpose vehicles as provided in 
paragraph (a)(3) of this section.
    (i) Two seaters. A car line shall be classed as ``Two Seater'' if 
the majority of the vehicles in that car line have no more than two 
designated seating positions as such term is defined in the regulations 
of the National Highway Traffic Safety Administration, Department of 
Transportation (DOT), 49 CFR 571.3.
    (ii) Minicompact cars. Interior volume index less than 85 cubic 
feet.
    (iii) Subcompact cars. Interior volume index greater than or equal 
to 85 cubic feet but less than 100 cubic feet.
    (iv) Compact cars. Interior volume index greater than or equal to 
100 cubic feet but less than 110 cubic feet.
    (v) Midsize cars. Interior volume index greater than or equal to 110 
cubic feet but less than 120 cubic feet.
    (vi) Large cars. Interior volume index greater than or equal to 120 
cubic feet.
    (vii) Small station wagons. Station wagons with interior volume 
index less than 130 cubic feet.
    (viii) Midsize station wagons. Station wagons with interior volume 
index greater than or equal to 130 cubic feet but less than 160 cubic 
feet.
    (ix) Large station wagons. Station wagons with interior volume index 
greater than or equal to 160 cubic feet.
    (2) The Administrator will classify light trucks (nonpassenger 
automobiles) into the following classes: Small pickup trucks, standard 
pickup trucks, vans, minivans, and SUVs. Starting in the 2013 model 
year, SUVs will be divided between small sport utility vehicles and 
standard sport utility vehicles. Pickup trucks and SUVs are separated by 
car line on the basis of gross vehicle weight rating (GVWR). For a 
product line with more than one GVWR, establish the characteristic GVWR 
value for the product line by calculating the arithmetic average of all 
distinct GVWR values less than or equal to 8,500 pounds available for 
that product line. The Administrator may determine that specific light 
trucks should be most appropriately placed in a different class or in 
the special purpose vehicle class as provided in paragraphs (a)(3)(i) 
and (ii) of this section, based on the features and characteristics of 
the specific vehicle, consumer information provided by the manufacturer, 
and other information available to consumers.
    (i) Small pickup trucks. Pickup trucks with a GVWR below 6,000 
pounds.
    (ii) Standard pickup trucks. Pickup trucks with a GVWR at or above 
6,000 pounds and at or below 8,500 pounds.
    (iii) Vans.
    (iv) Minivans.
    (v) Small sport utility vehicles. Sport utility vehicles with a GVWR 
below 6,000 pounds.
    (vi) Standard sport utility vehicles. Sport utility vehicles with a 
GVWR at or above 6,000 pounds and at or below 10,000 pounds.
    (3)(i) Special purpose vehicles. All automobiles with GVWR less than 
or equal to 8,500 pounds and all medium-duty passenger vehicles which 
possess special features and which the Administrator determines are more 
appropriately classified separately from typical automobiles or which do 
not meet the requirements of paragraphs (a)(1) and (2) of this section 
will be classified as special purpose vehicles. For example, the 
Administrator may determine that advanced technology vehicles (such as 
battery electric vehicles, fuel cell vehicles, plug-in hybrid electric 
vehicles and vehicles equipped with hydrogen internal combustion 
engines) should be appropriately classified as a type of ``special 
purpose vehicle.'' The Administrator may determine appropriate names for 
such types of special purpose vehicles, different from the name 
``special purpose vehicle.''
    (ii) All automobiles which possess features that could apply to two 
classes will be classified by the Administrator based on the 
Administrator's judgment on which class of vehicles consumers are more 
likely to make comparisons.

[[Page 952]]

    (4) Once a certain car line is classified by the Administrator, the 
classification will remain in effect for the model year.
    (b) Interior volume index--passenger automobiles. (1) The interior 
volume index shall be calculated for each car line which is not a ``two 
seater'' car line, in cubic feet rounded to the nearest 0.1 cubic foot. 
For car lines with more than one body style, the interior volume index 
for the car line is the arithmetic average of the interior volume 
indexes of each body style in the car line.
    (2) For all body styles except station wagons and hatchbacks with 
more than one seat (e.g., with a second or third seat) equipped with 
seatbelts as required by DOT safety regulations, interior volume index 
is the sum, rounded to the nearest 0.1 cubic feet, of the front seat 
volume, the rear seat volume(s), if applicable, and the luggage 
capacity.
    (3) For all station wagons and hatchbacks with more than one seat 
(e.g., with a second or third seat) equipped with seatbelts as required 
by DOT safety regulations, interior volume index is the sum, rounded to

the driving range using gasoline.
    (2) The natural gas dual fuel vehicle must be designed such that 
gasoline is used only when the natural gas tank is effectively empty, 
except for limited use of gasoline that may be required to initiate 
combustion.
    (3) Fuel consumption improvement. Calculate the separate air 
conditioning, off-cycle, and pickup truck fuel consumption improvement

          megagrams, from 40 CFR 86.1870-12(c), and rounded to the 
          nearest whole number; and
Production = the total production volume for the light truck category.
    (d) The Administrator may approve alternative calculation methods if 
they are part of an approved credit plan under the provisions of 15 
U.S.C. 2003.
    (e) For passenger automobile categories identified in paragraph 
(a)(1) of this section, the average fuel economy calculated in 
accordance with paragraph (c) of this section shall be adjusted using 
the following equation:

AFEadj = AFE[((0.55 x a x c) + (0.45 x c) + (0.5556 x a) + 
0.4487)/((0.55 x a) + 0.45)] + IW

Where:

    AFE = Average combined fuel economy as calculated in paragraph 
(c)(2) of this section, rounded to the nearest 0.0001 mpg;
AFE = Average combined fuel economy as calculated in paragraph (c) of 
          this section, rounded to the nearest 0.0001 mpg;
a = Sales-weight average (rounded to the nearest 0.0001 mpg) of all 
          model type highway fuel economy values (rounded to the nearest 
          0.1 mpg) divided by the sales-weighted average (rounded to the 
          nearest 0.0001 mpg) of all model type city fuel economy values 
          (rounded to the nearest 0.1 mpg). The quotient shall be 
          rounded to 4 decimal places. These average fuel economies 
          shall be determined using the methodology of paragraph (c) of 
          this section.
c = 0.0014;
IW = (9.2917 x 10-3 x SF3IWC x FE3IWC) 
          - (3.5123 x 10-3 x SF4ETW x 
          FE4IWC).
    Note: Any calculated value of IW less than zero shall be set equal 
to zero.

          decimal places.
FE4IWC = The sales-weighted average combined fuel economy of 
          all 3000 lb. inertia weight class base levels in the 
          compliance category. Round the result to the nearest 0.0001 
          mpg.
FE4IWC = The sales-weighted average combined fuel economy of 
          all 4000 lb. inertia weight class base levels in the 
          compliance category. Round the result to the nearest 0.0001 
          mpg.

    (f) The Administrator shall calculate and apply additional average 
fuel economy adjustments if, after notice and opportunity for comment, 
the Administrator determines that, as a result of test procedure changes 
not previously considered, such correction is necessary to yield fuel 
economy test results that are comparable to those obtained under the 
1975 test procedures. In making such determinations, the Administrator 
must find that:
    (1) A directional change in measured fuel economy of an average 
vehicle can be predicted from a revision to the test procedures;
    (2) The magnitude of the change in measured fuel economy for any 
vehicle or fleet of vehicles caused by a revision to the test procedures 
is quantifiable from theoretical calculations or best available test 
data;

[[Page 961]]

    (3) The impact of a change on average fuel economy is not due to 
eliminating the ability of manufacturers to take advantage of 
flexibility within the existing test procedures to gain measured 
improvements in fuel economy which are not the result of actual 
improvements in the fuel economy of production vehicles;
    (4) The impact of a change on average fuel economy is not solely due 
to a greater ability of manufacturers to reflect in average fuel economy 
those design changes expected to have comparable effects on in-use fuel 
economy;
    (5) The test procedure change is required by EPA or is a change 
initiated by EPA in its laboratory and is not a change implemented 
solely by a manufacturer in its own laboratory.
    (g)(1) Dual fuel automobiles must provide equal or greater energy 
efficiency while operating on the alternative fuel as while operating on 
gasoline or diesel fuel to obtain the CAFE credit determined in 
paragraphs (c)(2)(iv) and (v) of this section or to obtain the carbon-
related exhaust emissions credit determined in paragraphs (j)(2)(ii) and 
(iii) of this section. The following equation must hold true:

Ealt/Epet = 1

Where:

Ealt = [FEalt/(NHValt x 
          Dalt)] x 10\6\ = energy efficiency while operating 
          on alternative fuel rounded to the nearest 0.01 miles/million 
          BTU.
Epet = [FEpet/(NHVpet x 
          Dpet)] x 10\6\ = energy efficiency while operating 
          on gasoline or diesel (petroleum) fuel rounded to the nearest 
          0.01 miles/million BTU.
FEalt is the fuel economy [miles/gallon for liquid fuels or 
          miles/100 standard cubic feet for gaseous fuels] while 
          operated on the alternative fuel as determined in Sec.  
          600.113-12(a) and (b).
FEpet is the fuel economy [miles/gallon] while operated on 
          petroleum fuel (gasoline or diesel) as determined in Sec.  
          600.113-12(a) and (b).
NHValt is the net (lower) heating value [BTU/lb] of the 
          alternative fuel.
NHVpet is the net (lower) heating value [BTU/lb] of the 
          petroleum fuel.
Dalt is the density [lb/gallon for liquid fuels or lb/100 
          standard cubic feet for gaseous fuels] of the alternative 
          fuel.
Dpet is the density [lb/gallon] of the petroleum fuel.

    (i) The equation must hold true for both the FTP city and HFET 
highway fuel economy values for each test of each test vehicle.
    (ii)(A) The net heating value for alcohol fuels shall be premeasured 
using a test method which has been approved in advance by the 
Administrator.
    (B) The density for alcohol fuels shall be premeasured using ASTM D 
1298 (incorporated by reference at Sec.  600.011).
    (iii) The net heating value and density of gasoline are to be 
determined by the manufacturer in accordance with Sec.  600.113.

1993 through 2019 must meet the minimum driving range requirements 
established by the Secretary of Transportation (49 CFR part 538) to 
obtain the CAFE credit determined in paragraphs (c)(2)(iv) and (v) of 
this section.
    (h) The increase in average fuel economy determined in paragraph (c) 
of this section attributable to dual fueled automobiles is subject to a 
maximum value through model year 2019 that applies separately to each 
category of automobile specified in paragraph (a)(1) of this section. 
The increase in average fuel economy attributable to vehicles fueled by 
electricity or, for model years 2016 and later, by compressed natural 
gas, is not subject to a maximum value. The increase in average fuel 
economy attributable to alcohol dual fuel model types calculated under 
paragraph (c)(2)(v) of this section is also not subject to a maximum 
value. The following maximum values apply under this paragraph (h):

automobile identified in paragraph (a)(1) of this section, the maximum 
decrease in average carbon-related exhaust emissions determined in 
paragraph (j) of this section attributable to alcohol dual fuel 
automobiles and natural gas dual fuel automobiles shall be calculated 
using the following formula, and rounded to the nearest tenth of a gram 
per mile:

Where:

FltAvg = The fleet average CREE value in grams per mile, rounded to the 
          nearest whole number, for passenger automobiles or light 
          trucks determined for the applicable model year according to

          dual fuel and natural gas dual fuel automobiles are operated 
          exclusively on gasoline (or diesel) fuel. For the purposes of 
          these calculations, the values for natural gas dual fuel 
          automobiles using the optional Utility Factor approach in 
          paragraph (j)(2)(vii) of this section shall not be the 
          gasoline CREE values, but the CREE values determined in 
          paragraph (j)(2)(vii) of this section.
MPGMAX = The maximum increase in miles per gallon determined 
          for the appropriate model year in paragraph (h) of this 
          section.

    (1) The Administrator shall calculate the decrease in average 
carbon-related exhaust emissions to determine if the maximum decrease 
provided in this paragraph (i) has been reached. The Administrator shall 
calculate the average carbon-related exhaust emissions for each category 
of automobiles specified in paragraph (a) of this section by subtracting 
the average carbon-related exhaust emission values determined in 
paragraph (j) of this section from the average carbon-related exhaust 
emission values calculated in accordance with this section by assuming 
all alcohol dual fuel and natural gas dual fuel automobiles are operated 
exclusively on gasoline (or diesel) fuel. For the purposes of these 
calculations, the values for natural gas dual fuel automobiles using the 
optional Utility Factor approach in paragraph (j)(2)(vii) of this 
section shall not be the gasoline CREE values, but the CREE values 
determined in paragraph (j)(2)(vii) of this section. The difference is 
limited to the maximum decrease specified in paragraph (i) of this 
section.
    (2) [Reserved]
    (j) The average carbon-related exhaust emissions will be calculated

automobiles into:
    (2) A sum of terms, each of which corresponds to a model type within 
that category of automobiles and is a product determined by multiplying 
the number of automobiles of that model type produced by the 
manufacturer in the model year by:

    (B) Model year 2016 through 2020 natural gas dual fuel model types 
must meet the following criteria to qualify for use of a Utility Factor 
greater than 0.5:
    (1) The driving range using natural gas must be at least two times 
the driving range using gasoline.
    (2) The natural gas dual fuel vehicle must be designed such that 
gasoline is used only when the natural gas tank is effectively empty, 
except for limited use of gasoline that may be required to initiate 
combustion.
    (k) Alternative in-use weighting factors for dual fuel model types. 
Using one of the methods in either paragraph (k)(1) or (2) of this 
section, manufacturers may request the use of alternative values for the 
weighting factor F in the equations in paragraphs (j)(2)(vi) and (vii) 
of this section. Unless otherwise approved by the Administrator, the 
manufacturer must use the value of F that is in effect in paragraphs 
(j)(2)(vi) and (vii) of this section.
    (1) Upon written request from a manufacturer, the Administrator will 
determine and publish by written guidance an appropriate value of F for 
each requested alternative fuel based on the Administrator's assessment 
of real-world use of the alternative fuel. Such published values would 
be available for any manufacturer to use. The Administrator will 
periodically update these values upon written request from a 
manufacturer.
    (2) The manufacturer may optionally submit to the Administrator its 
own demonstration regarding the real-world use of the alternative fuel 
in their vehicles and its own estimate of the appropriate value of F in 
the equations in paragraphs (j)(2)(vi) and (vii) of this section. 
Depending on the nature of the analytical approach, the manufacturer 
could provide estimates of F that are model type specific or that are 
generally applicable to the manufacturer's dual fuel fleet. The 
manufacturer's analysis could include use of data gathered from on-board 
sensors and computers, from dual fuel vehicles in fleets that are 
centrally fueled, or from other sources. The analysis must be based on 
sound statistical methodology and must account for analytical 
uncertainty. Any approval by the Administrator will pertain to the use 
of values of F for the model types specified by the manufacturer.

Sec.  600.511-08  Determination of domestic production.

    (a) Except with advance approval of the Administrator, an automobile 
shall be considered domestically produced in any model year if it is 
included within a domestically produced car line (car

[[Page 965]]

line includes station wagons for purposes of this paragraph), unless the 
assembly of such automobile is completed in Canada or Mexico and such 
automobile is not imported into the United States prior to the 
expiration of 30 days following the end of the model year. For purposes 
of this paragraph a car line will be considered domestically produced if 
the following ratio is less than 0.25:
    (1) The sum of the declared value, as defined in Sec.  600.502, of 
all of the imported components installed or included on automobiles 
produced within such a car line within a given model year plus the cost 
of transportation and insuring such components to the United States port 
of entry, the Mexican port of entry (when paragraph (b)(3) of this 
section applies), or the Canadian port of entry but exclusive of any 
customs duty, divided by
    (2) The cost of production, as defined in Sec.  600.502, of 
automobiles within such car line.
    (b) For the purposes of calculations under this subpart with respect 
to automobiles manufactured during any model year,
    (1) An average exchange rate for the country of origin of each 
imported component shall be used that is calculated by taking the mean 
of the exchange rates in effect at the end of each quarter set by the 
Federal Reserve Bank of New York for twelve calendar quarters prior to 
and including the calendar quarter ending one year prior to the date 
that the manufacturer submits the calculation of the preliminary average 
for such model year. Such rate, once calculated, shall be in effect for 
the duration of the model year. Upon petition of a manufacturer, the 
Administrator may permit the use of a different exchange rate where 
appropriate and necessary.
    (2) For automobiles for which paragraph (b)(3) of this section does 
not apply pursuant to the schedule in paragraph (b)(4), components shall 
be considered imported unless they are either:
    (i) Wholly the growth, product, or manufacture of the United States 
and/or Canada, or
    (ii) Substantially transformed in the United States or Canada into a 
new and different article of commerce.
    (3) For automobiles for which this paragraph applies pursuant to the 
schedule in paragraph (b)(4) of this section, components shall be 
considered imported unless they are either:
    (i) Wholly the growth, product, or manufacture of the United States 
and/or Canada and/or Mexico, or
    (ii) Substantially transformed in the United States and/or Canada 
and/or Mexico into a new and different article of commerce.
    (4) Paragraphs (b)(4) (i) through (v) of this section set forth the 
schedule according to which paragraph (b)(3) of this section applies for 
all automobiles manufactured by a manufacturer and sold in the United 
States, wherever assembled.
    (i) With respect to a manufacturer that initiated the assembly of 
automobiles in Mexico before model year 1992, the manufacturer may 
elect, at any time between January 1, 1997, and January 1, 2004, to have 
paragraph (b)(3) of this section apply to all automobiles it 
manufactures, beginning with the model year commencing after the date of 
such election.
    (ii) With respect to a manufacturer initiating the assembly of 
automobiles in Mexico after model year 1991, paragraph (b)(3) of this 
section shall apply to all automobiles it manufactures, beginning with 
the model year commencing after January 1, 1994, or the model year 
commencing after the date that the manufacturer initiates the assembly 
of automobiles in Mexico, whichever is later.
    (iii) With respect to a manufacturer not described by paragraph 
(b)(4) (i) or (ii) of this section assembling automobiles in the United 
States or Canada but not in Mexico, the manufacturer may elect, at any 
time between January 1, 1997, and January 1, 2004, to have paragraph 
(b)(3) of this section apply to all automobiles it manufactures, 
beginning with the model year commencing after the date of such 
election, except that if such manufacturer initiates the

[[Page 966]]

assembly of automobiles in Mexico before making such election, this 
paragraph shall not apply, and the manufacturer shall be subject to 
paragraph (b)(4)(ii) of this section.
    (iv) With respect to a manufacturer not assembling automobiles in 
the United States, Canada, or Mexico, paragraph (b)(3) of this section 
shall apply to all automobiles it manufactures, beginning with the model 
year commencing after January 1, 1994.
    (v) With respect to a manufacturer authorized to make an election 
under paragraph (b)(4) (i) or (iii) of this section which has not made 
that election within the specified period, paragraph (b)(3) of this 
section shall apply to all automobiles it manufactures, beginning with 
the model year commencing after January 1, 2004.
    (5) All elections under paragraph (b)(4) of this section shall be 
made in accordance with the procedures established by the Secretary of 
Transportation pursuant to 49 U.S.C. 32904(b)(3)(C).
    (c) If it is determined by the Administrator at some date later than 
the date of entry that the declared value of such imported components 
did not represent fair market value at the date of entry, through U.S. 
Bureau of Customs appraisals, the Administrator may review the 
determination made pursuant to paragraph (a) of this section as to 
whether the pertinent car lines which utilize such components were 
correctly included within the manufaturer's domestically-produced or 
foreign-produced fleets. If such a determination was in error due to 
misrepresentation of the valuation of imported components at the date of 
entry, the Administrator may recalculate the manufacturer's average for 
the affected model year, according to Sec.  600.510, to reflect the 
correct valuation of such imported components in each affected car line.

Sec.  600.513-08  Gas Guzzler Tax.

    (a) This section applies only to passenger automobiles sold after 
December 27, 1991, regardless of the model year of those vehicles. For 
alcohol dual fuel and natural gas dual fuel automobiles, the fuel 
economy while such automobiles are operated on gasoline will be used for 
Gas Guzzler Tax assessments.
    (1) The provisions of this section do not apply to passenger 
automobiles exempted for Gas Guzzler Tax assessments by applicable 
Federal law and

[[Page 968]]

regulations. However, the manufacturer of an exempted passenger 
automobile may, in its discretion, label such vehicles in accordance 
with the provisions of this section.
    (2) For 1991 and later model year passenger automobiles, the 
combined FTP/HFET-based model type fuel economy value determined in 
Sec.  600.208 used for Gas Guzzler Tax assessments shall be calculated 
in accordance with the following equation, rounded to the nearest 0.1 
mpg:


FEadj = FE[((0.55 x ag x c) + (0.45 x c) + (0.5556 
x ag) + 0.4487)/((0.55 x ag) + 0.45)] + 
IWg

Where:

FEadj = Fuel economy value to be used for determination of 
          gas guzzler tax assessment rounded to the nearest 0.1 mpg.
FE = Combined model type fuel economy calculated in accordance with 
          Sec.  600.208, rounded to the nearest 0.0001 mpg.
ag = Model type highway fuel economy, calculated in 
          accordance with Sec.  600.208, rounded to the nearest 0.0001 
          mpg divided by the model type city fuel economy calculated in 
          accordance with Sec.  600.208, rounded to the nearest 0.0001 
          mpg. The quotient shall be rounded to 4 decimal places.
c = gas guzzler adjustment factor = 1.300 x 10-3 for the 1986 
          and later model years.
IWg = (9.2917 x 10-3 x 
          SF3IWCGFE3IWCG) - (3.5123 x 
          10-3 x SF4ETWG x FE4IWCG).
    Note: Any calculated value of IW less than zero shall be set equal 
to zero.
SF3IWCG = The 3000 lb. inertia weight class sales in the 
          model type divided by the total model type sales; the quotient 
          shall be rounded to 4 decimal places.
SF4ETWG = The 4000 lb. equivalent test weight sales in the 
          model type divided by the total model type sales, the quotient 
          shall be rounded to 4 decimal places.
FE3IWCG = The 3000 lb. inertial weight class base level 
          combined fuel economy used to calculate the model type fuel 
          economy rounded to the nearest 0.0001 mpg.
FE4IWCG = The 4000 lb. inertial weight class base level 
          combined fuel economy used to calculate the model type fuel 
          economy rounded to the nearest 0.001 mpg.

    (b)(1) For passenger automobiles sold after December 31, 1990, with 
a combined FTP/HFET-based model type fuel economy value of less than 
22.5 mpg (as determined in Sec.  600.208), calculated in accordance with 
paragraph (a)(2) of this section and rounded to the nearest 0.1 mpg, 
each vehicle fuel economy label shall include a Gas Guzzler Tax 
statement pursuant to 49 U.S.C. 32908(b)(1)(E). The tax amount stated 
shall be as specified in paragraph (b)(2) of this section.
    (2) For passenger automobiles with a combined general label model 
type fuel economy value of:

Sec.  600.514-12  Reports to the Environmental Protection Agency.

    This section establishes requirements for automobile manufacturers 
to submit reports to the Environmental Protection Agency regarding their 
efforts to reduce automotive greenhouse gas emissions.
    (a) General Requirements. (1) For each model year, each manufacturer 
shall submit a pre-model year report.
    (2) The pre-model year report required by this section for each 
model year must be submitted before the model year begins and before the 
certification of any test group, no later than December 31 of the 
calendar year two years before the model year. For example the pre-model 
year report for the 2012 model year must be submitted no later than 
December 31, 2010.
    (3) Each report required by this section must:
    (i) Identify the report as a pre-model year report;
    (ii) Identify the manufacturer submitting the report;
    (iii) State the full name, title, and address of the official 
responsible for preparing the report;
    (iv) Be submitted to: Director, Compliance and Innovative Strategies 
Division, U.S. Environmental Protection Agency, 2000 Traverwood, Ann 
Arbor, Michigan 48105;
    (v) Identify the current model year;

[[Page 969]]

    (vi) Be written in the English language; and
    (vii) Be based upon all information and data available to the 
manufacturer approximately 30 days before the report is submitted to the 
Administrator.
    (b) Content of pre-model year reports. (1) Each pre-model year 
report must include the following information for each compliance 
category for the applicable future model year and to the extent 
possible, two model years into the future:
    (i) The manufacturer's estimate of its footprint-based fleet average 
CO2 standards (including temporary lead time allowance 
alternative standards, if applicable);
    (ii) Projected total and model-level production volumes for each 
applicable standard category;
    (iii) Projected fleet average CO2 compliance level for 
each applicable standard category; and the model-level CO2 
emission values which form the basis of the projection;
    (iv) Projected fleet average CO2 credit/debit status for 
each applicable standard category;
    (v) A description of the various credit, transfer and trading 
options that will be used to comply with each applicable standard 
category, including the amount of credit the manufacturer intends to 
generate for air conditioning leakage, air conditioning efficiency, off-
cycle technology, advanced technology vehicles, hybrid or low-emission 
full size pickup trucks, and various early credit programs;
    (vi) A description of the method which will be used to calculate the 
carbon-related exhaust emissions for any electric vehicles, fuel cell 
vehicles and plug-in hybrid vehicles;
    (vii) A summary by model year (beginning with the 2009 model year) 
of the number of electric vehicles, fuel cell vehicles, plug-in hybrid 
electric vehicles, dedicated compressed natural gas vehicles, and dual 
fuel natural gas vehicles using (or projected to use) the advanced 
technology vehicle credit and incentives program, including the 
projected use of production multipliers;
    (viii) The methodology which will be used to comply with 
N2O and CH4 emission standards; and
    (ix) Notification of the manufacturer's intent to exclude emergency 
vehicles from the calculation of fleet average standards and the end-of-
year fleet average, including a description of the excluded emergency 
vehicles and the quantity of such vehicles excluded.
    (x) Other information requested by the Administrator.
    (2) Manufacturers must submit, in the pre-model year report for each 
model year in which a credit deficit is generated (or projected to be 
generated), a compliance plan demonstrating how the manufacturer will 
comply with the fleet average CO2 standard by the end of the 
third year after the deficit occurred.

     Sec. Appendix II to Part 600--Sample Fuel Economy Calculations

    (a) This sample fuel economy calculation is applicable to 1978 
through 1987 model year automobiles.
    (1) Assume that a gasoline-fueled vehicle was tested by the Federal 
Emission Test Procedure and the following results were calculated:

HC = .139 grams/mile
CO = 1.59 grams/mile
CO2 = 317 grams/mile

    According to the procedure in Sec.  600.113-78, the city fuel 
economy or MPGc, for the vehicle may be calculated by 
substituting the HC, CO, and CO2 grams/mile values into the 
following equation.
[GRAPHIC] [TIFF OMITTED] TC15NO91.202

MPGc = 27.7

    (2) Assume that the same vehicle was tested by the Federal Highway 
Fuel Economy Test Procedure and calculation similar to that shown in 
paragraph (a) by this appendix resulted in a highway fuel economy or 
MPGh of 36.9. According to the procedure in Sec.  600.113, 
the combined fuel economy (called MPGc/h) for the vehicle may 
be calculated by substituting the city and highway fuel economy values 
into the following equation:
[GRAPHIC] [TIFF OMITTED] TC15NO91.203


[[Page 972]]


    (b) This sample fuel economy calculation is applicable to 1988 and 
later model year automobiles.
    (1) Assume that a gasoline-fueled vehicle was tested by the Federal 
Emission Test Procedure and the following results were calculated:

HC = .139 grams/mile.
CO = 1.59 grams/mile.
CO2 = 317 grams/mile.

    (2) Assume that the test fuel used for this test had the following 
properties:

SG = 0.745.
CWF = 0.868.
NHV = 18,478 Btu/lb.

    (3) According to the procedure in Sec.  600.113-08, the city fuel 
economy or MPGc, for the vehicle may be calculated by 
substituting the HC, CO, and CO2 gram/mile values and the SG, 
CWF, and NHV values into the following equation:

MPGc = (5174 x 10\4\ x CWF x SG) / [((CWF x HC) + (0.429 x CO 
          + (0.273 x CO2)) ((0.6 x SG x NHV) + 5471)]

    Example:

MPGc = (5174 x 10 \4\ x 0.868 x 0.745) / [(0.868 x .139 + 
          0.429 x 1.59 + 0.273 x 317)(0.6 x 0.745 x 18478 + 5471)]
MPGc = 27.9

    (4) Assume that the same vehicle was tested by the Federal Highway 
Fuel Economy Test Procedure and a calculation similar to that shown in 
(b)(3) of this section resulted in a highway fuel economy of 
MPGh of 36.9. According to the procedure in Sec.  600.210-
08(c) or Sec.  600.210-12(c), the combined fuel economy (called 
MPGcomb) for the vehicle may be calculated by substituting 
the city and highway fuel economy values into the following equation:

  Sec. Appendix III to Part 600--Sample Fuel Economy Label Calculation

    Suppose that a manufacturer called Mizer Motors has a product line 
composed of eight car lines. Of these eight, four are available with the 
3.0 liter, 6 cylinder, sequential multi-point fuel injection, 4-valve 
per cylinder, and 3-way catalyst engine. These four car lines are:

Ajax
Boredom III
Dodo
Castor (Station Wagon)

    A. A car line is defined in subpart A (with additional guidance 
provided in EPA Advisory Circular 89) as a group of vehicles within a 
make or division which has a degree of commonality in construction. Car 
line does not consider any level of decor or opulence and is not 
generally distinguished by such characteristics as roofline, number of 
doors, seats, or windows. Station wagons and light duty trucks are, 
however, identified separately from the remainder of each car line. In 
other words, a Castor station wagon would be considered a different car 
line than the normal Castor car line made up of sedans, coupes, etc.
    B. The engine considered here is defined as a basic engine in 
subpart A of this part (with additional guidance provided in EPA 
Advisory Circular 83A). A basic engine is a unique combination of 
manufacturer, engine displacement, number of cylinders, fuel system, 
catalyst usage and other engine and emission control system 
characteristics specified by the Administrator. A model type is a unique 
combination of car line, basic engine,

[[Page 973]]

and transmission class. Thus Ajax is a car line but Ajax 3.0 liter, 6 
cylinder manual four-speed transmission is a model type whereas Ajax 3.0 
liter, 6 cylinder automatic three-speed transmission is a different 
model type.
    C. The following calculations provide an example of the procedures 
described in subpart C of this part for the calculation of vehicle 
configuration and model type fuel economy values. In order to simplify 
the presentation, only city fuel economy values are included (as 
determined by either the derived 5-cycle method or vehicle-specific 5-
cycle based method). The procedure is identical for highway and combined 
fuel economy values.
    Step I. Input data as supplied by the manufacturer or as determined 
from testing conducted by the Administrator.

                       Manufacturer--Mizer Motors

    Basic Engine: (3.0 liter, 6 cylinder, sequential multi-point fuel 
injection, 4-valve per cylinder, 3-way catalyst).

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

    Step III. Determine base level fuel economy values.
    A. For all the base levels except the base level which includes 
4,000 pound, manual four-speed transmission data, the base level fuel 
economy is as noted in Step II since only one vehicle configuration was 
tested within each of these base levels.

------------------------------------------------------------------------
 
------------------------------------------------------------------------
3,500 lb/M4 transmission..................  16.1001 mpg.
3,500 lb/A3 transmission..................  15.9020 mpg.
4,000 lb/A3 transmission..................  13.8138 mpg.
4,500 lb/A3 transmission..................  13.2203 mpg.
5,000 lb/A3 transmission..................  10.6006 mpg.
------------------------------------------------------------------------

    B. Since data from more than one vehicle configuration are included 
in the 4,000-pound, manual four-speed transmission base level, this fuel 
economy is harmonically averaged in proportion to the percentage of 
total sales of all vehicle configurations tested within that base level 
represented by each vehicle configuration tested within that base level.

    Base level: M4 transmission, 4000 pounds:
    [GRAPHIC] [TIFF OMITTED] TR27DE06.084
    
    Therefore, the 4000 pound, M4 transmission fuel economy is 14.6840 
miles per gallon.
    Note that the car line of the test vehicle using a given engine 
makes no difference--only the weight and transmission do.
    Step IV. For each model type offered by the manufacturer with that 
basic engine, determine the sales fraction represented by each inertia 
weight/transmission class combination and the corresponding fuel 
economy.

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

    Step V. Determine fuel economy for each model type (that is, car 
line/basic engine/transmission class combination).
    Ajax, 3.0 liter, 6 cylinder, A3 transmission, model type MPG is 
calculated as follows:

[[Page 975]]


    Similarly, Ajax and Dodo 3.0 liter, 6 cylinder, M4 model type MPG is 
calculated as follows:

    Dodo 3.0 liter, 6 cylinder, A3 model type MPG is calculated as

    Boredom III 3.0 liter 6 cylinder M4 model type MPG = 14.6840 mpg, 
which rounds to 15 mi./gal\1\
---------------------------------------------------------------------------

    \1\ The model type fuel economy values rounded to the nearest mile 
per gallon, are the fuel economy values listed in the EPA Fuel Economy 
Guide and used on the general labels (window stickers) for production 
vehicles for that model year.

                           K. Style Guidelines

    (a) Fuel economy labels must be printed on white or very light 
paper. Any label markings for which colors are not specified must be in 
black and white as shown. Some portions of the label must be filled with 
a blue or blue-shaded color as specified in subpart D of this part. Use 
the color blue defined in CMYK values of 40c-10m-0y-0k, or it may be 
specified as Pantone 283.
    (b) Use a Univers font from Adobe or another source that properly 
reproduces the labels as shown in the samples. Use Light (L), Roman (R), 
Bold (B) or Black (Bl) font weights as noted. Font size is shown in 
points, followed by leading specifications in points to indicate line 
spacing (if applicable). Use white characters in black fields; use black 
characters in all other places. Unless noted otherwise, text is left-
justified with a 1.6 millimeter margin. Some type may need tracking 
adjustments to fit in the designated space.
    (c) Use the following conventions for lines and borders:
    (1) Narrow lines defining the border or separating the main fields 
are 1.6 millimeter thick.
    (2) Each rectangular shape or area, including the overall label 
outline, has an upper left corner that is square (0 radius). All other 
corners have a 3.2 millimeter radius.
    (d) Fuel and vehicle icons, range and slider bars, and agency names 
and logos are available electronically.

                 Test Procedures and Evaluation Criteria



                      Subpart A_General Provisions



Sec.  610.10  Program purpose.

    (a) The purpose of an evaluation program initiated under these rules 
is to determine, in accordance with standardized procedures, the 
performance of various retrofit devices applicable to automobiles for 
which fuel economy improvement claims are made, and to compile and 
disseminate the results of the evaluation. It should be stressed that 
the role of this program will be the generation, analysis and 
dissemination of technical data, and not the approval or certification 
of retrofit devices.
    (1) Through engineering or statistical analysis of data from vehicle 
tests, the evaluation program will determine the effects on fuel 
economy, exhaust emissions, durability and driveability of the 
applicable vehicles due to the installation or use of the devices. The 
evaluation program will also include additional procedures, whenever 
determined by the Administrator as necessary, to evaluate the durability 
of the devices themselves, their effects on vehicle durability or other 
effects only evident over the course of extended mileage accumulation.
    (b) Data generated in an evaluation program by the Administrator of 
the Environmental Protection Agency (EPA) are public information and 
will be published in the Federal Register and elsewhere for use by the 
Federal Trade Commission and the public. The results of any evaluation 
conducted by the Administrator may be used in any subsequent 
investigation or enforcement action in the event that a device is 
marketed in violation of Federal or state law.



Sec.  610.11  Definitions.

[44 FR 17946, Mar. 23, 1979, as amended at 49 FR 18489, May 1, 1984]



Sec.  610.12  Program initiative.

    A retrofit device evaluation program will be initiated as follows:
    (a) At the request of the Federal Trade Commission (FTC) when it has 
reason to believe that fuel economy representation made for a retrofit 
device being marketed may be inadequate,

[[Page 986]]

    (b) At the EPA Administrator's initiative, or
    (c) Upon the application of any manufacturer of a retrofit device 
(or prototype thereof) for which a fuel economy improvement claim is 
made.



Sec.  610.13  Program structure.

    (a) Each device evaluation program will consist of up to three 
phases:
    (1) A preliminary analysis of available information and test data on 
the device to be performed by the EPA Administrator;
    (2) Designing and conducting of a sequence of tests to determine 
device effectiveness if considered necessary by virtue of the 
Administrator's preliminary analysis; and
    (3) Publication in the Federal Register, and submission to the 
Department of Transportation and to the Federal Trade Commission, of a 
summary of the results of any tests conducted under subparts C through 
F, or if none were conducted, then a summary of the results of the 
preliminary analysis conducted under subpart B; together with the 
Administrator's conclusions as to the effect of the tested retrofit 
device on fuel economy and exhaust emissions, and as to any other 
information that the Administrator determines is relevant in evaluating 
such device.
    (b) Each of the above phases may, as appropriate, include the use of 
statistically valid sample sizes and statistical evaluation of measured 
results.



Sec.  610.14  Payment of program costs.

    (a) All costs incurred in an evaluation program initiated at the 
request of the FTC or at the Administrator's initiative, including the 
cost of purchasing any necessary quantity of the device under 
evaluation, will be borne by the United States.
    (b) For those evaluation programs initiated at the request of a 
manufacturer of a retrofit device, should the Administrator test the 
device, or cause the device to be tested, as part of the evaluation, 
then that manufacturer shall supply, at his own expense, one or more 
samples of the device to the Administrator and shall be liable for the 
costs of testing which are incurred by the Administrator. The 
manufacturer shall also be liable for the cost of any preliminary 
testing at an independent testing laboratory performed as part of the 
evaluation program. Apart from the costs of testing a device, EPA shall 
be responsible for costs of formulating its engineering evaluation of a 
device.

[44 FR 17946, Mar. 23, 1979, as amended at 49 FR 18838, May 3, 1984]



Sec.  610.15  Eligibility for participation.

    Participation in an evaluation program initiated under Sec.  
610.12(c) will be available to any person or company who agrees to 
follow the procedures set forth in these protocols. Failure to conform 
to any aspect of these protocols, without the approval of the 
Adminstrator, may be interpreted as withdrawal from participation in the 
program.



Sec.  610.16  Applicant's responsibilities.

    Each applicant for evaluation under Sec.  610.12(c) will be 
responsible for the following:
    (a) Submission of an application, in the format specified by the 
Administrator, prior to initiation of the evaluation. A separate 
application shall be made for each different device. The application 
shall be made to the Administrator (or his delegate) by the manufacturer 
and shall be updated and corrected by amendment if deemed necessary by 
EPA.
    (b) The application shall be in writing, signed by an authorized 
representative of the manufacturer, and shall include the following:
    (1) Identification and description of the device covered by the 
application, including drawings, schematics and information on the 
theory of operation.
    (2) Vehicles or engines to which the device is applicable and a 
description of the types of vehicles or engines to which it is not 
applicable, e.g., would not provide a benefit, a benefit less than 
claimed for the device in general, or would result in a safety hazard or 
damage to the engine. If the reason for inapplicability is safety or 
damage related, this must be explained as required by paragraph (b)(7) 
of this section.
    (3) Installation or usage instructions, including degree of 
knowledge required by persons making the installation and the tools and 
equipment required.

[[Page 987]]

    (4) A statement of recommended maintenance, degree of knowledge 
required for that maintenance, and the tools and equipment required to 
perform the maintenance.
    (5) All data regarding exhaust emissions regulated by EPA under 
Sec.  202 of the Clean Air Act and fuel economy test data on the device 
or product available to the applicant.
    (6) All information available to the applicant concerning whether 
the device in its operation, function, or malfunction may cause an 
automobile using that device to emit into the ambient air any substance 
other than pollutants regulated by EPA under section 202 of the Clean 
Air Act (i.e., hydrocarbons, carbon monoxide, and oxides of nitrogen), 
or natural gaseous atmospheric constituents (such as carbon dioxide, or 
water vapor) in a quantity differing from that emitted in the operation 
of the automobile without the device.
    (7) All information available to the applicant concerning whether 
and under what conditions the device in its operation, function or 
malfunction may result in damage to an automobile or endanger its 
occupants or persons or property in close proximity to the automobile.
    (c) Shipment to the EPA's Motor Vehicle Emission Laboratory, or 
other test site designated by the Administrator, of the devices being 
evaluated in the quantity specified by the Administrator.
    (d) Complete copies of the application and of any amendments thereto 
shall be submitted in such multiple copies as the Administrator may 
require.



Sec.  610.17  Application format.

    (a) Device manufactures who apply for evaluation of a fuel economy 
retrofit device should use the standard application format, in order to 
allow the Administrator to compile relevant data on specific devices and 
to allow timely response to applications. Application formats are 
available from and submissions shall be made to:

    Director, Emission Control Technology Division, Environmental 
Protection Agency, 2565 Plymouth Road, Ann Arbor, Michigan 48105. Attn: 
Fuel Economy Retrofit Device Evaluation.

    (b) Four weeks should be allowed for analysis of the application and 
preparation of a response. As indicated in other sections of this part, 
this response will include the evaluation of the device according to the 
criteria discussed in subpart B of this part. The results of the 
Administrator's evaluation will be made public.



       Subpart B_Evaluation Criteria for the Preliminary Analysis



Sec.  610.20  General.

    The Administrator will employ the following criteria for evaluating 
the accuracy of fuel economy representations made with respect to 
retrofit devices:
    (a) Device functional category;
    (b) Device integrity;
    (c) Operator interaction effects;
    (d) Validity of test data;
    (e) Evaluation of test data;

as these concepts are explained in Sec. Sec.  610.21 through 610.25 
respectively.



Sec.  610.21  Device functional category and vehicle system effects.

    (a) The devices evaluated in this program are organized into 
categories for purposes of definition and establishment of evaluation 
criteria and test procedures, and to indicate which vehicle functional 
characteristics (other than fuel economy) may be adversely affected by 
installation or use of the device.
    (b) A device's category will be based on:
    (1) Engineering principles governing operation of the device;
    (2) Interaction between the device and specific vehicle/engine 
operating characteristics; and
    (3) Constraints with respect to vehicle applicability of the device.
    (c) The device categories and the vehicle functional characteristics 
which may be adversely affected are noted for each device category in 
Table I. The notation for each characteristic is as follows:

vehicle operation and performance, the Administrator will require such 
tests to be conducted prior to the publication of a complete evaluation 
of the device.

[44 FR 17946, Mar. 23, 1979, as amended at 49 FR 18489, May 1, 1984]



Sec.  610.22  Device integrity.

    The integrity of a device will be evaluated with respect to:
    (a) The extent to which device manufacture is standardized by means 
of drawings, specifications, and other fabrication and quality assurance 
controls;
    (b) The degree of sensitivity of device effectiveness to 
deterioration under exposure to normal operating conditions.
    (c) The susceptibility of the device to deterioration of 
effectiveness under abnormal operating conditions;
    (d) The effect upon its surroundings of device malfunction which may 
be reasonably anticipated to occur in actual use; and
    (e) The extent to which test data support (b), (c) and (d).



Sec.  610.23  Operator interaction effects.

    The device will also be evaluated with respect to:
    (a) The degree of sensitivity of device effectiveness to variances 
in installation, operation and maintenance;
    (b) The adequacy of manufacturer-furnished instructions for 
minimizing variances in installation, operation and maintenance;
    (c) The extent to which device installation or use, or the effects 
of such installation or use, relate to Federal emission control 
regulations;
    (d) Effects on the performance, safety, or occupant comfort of the 
retrofitted vehicle, and on that of other vehicles; and
    (e) The relationship between total cost of ownership of the device 
(purchase price plus maintenance costs) and the cost savings realizable 
from its fuel economy effects.



Sec.  610.24  Validity of test data.

    The Administrator will make a determination as to the validity of 
manufacturer-furnished test data on the basis of:
    (a) The correlation between the test procedures used by the 
manufacturer or testing agent and the procedures prescribed in subpart 
D;
    (b) The choice of test vehicle(s) as representative of the 
manufacturer's claim for operation and/or principles of operation;

[[Page 989]]

    (c) The degree of control exercised over ambient and operating 
conditions in the tests, including vehicle calibrations;
    (d) Accuracy and precision of the measurement techniques and 
instrumentation used in the tests;
    (e) Disclosure of all test data acquired on the device, whether 
representing positive, negative, or inconclusive results;
    (f) Qualifications and independence of the testing agent; and
    (g) The extent to which test data include evaluation of the 
durability of the device, or its effect on vehicle durability.



Sec.  610.25  Evaluation of test data.

    Valid manufacturer-furnished test data will be evaluated with 
respect to:
    (a) Vehicle applicability;
    (b) Dependence of device effects upon vehicle type;
    (c) Device effects on fuel economy, and on emissions, with 
statistical or other caveats as established by the data base;
    (d) Definition of claims which can be made based on the available 
data; and
    (e) Substantiation of specified claims made by the manufacturer.



                   Subpart C_Test Requirement Criteria



Sec.  610.30  General.

    (a) If the Administrator determines, by the criteria given in 
subpart B, that the claims made for a device are not supported by 
existing test data or other information, the Administrator will request 
the manufacturer to furnish additional information, and may design a 
test program to investigate those areas where claims appear to be 
erroneous or unsupported or where adverse effects due to use of the 
device are suspected.
    (b) In cases where the Administrator determines on the basis of the 
preliminary analysis that a device either can have no significant 
beneficial effect on fuel economy, or will have an adverse effect on 
emissions, he may elect not to design a test program or test the device 
and to publish only his preliminary analysis and conclusions.
    (c) If the evaluation was initiated upon application of a 
manufacturer (as described in Sec.  610.12(c)) and the manufacturer 
elects not to have the device tested, the Administrator's preliminary 
analysis and conclusions will be published.
    (d) For each device that the Agency intends to test, the 
Administrator will give the manufacturer prior notice by mail of the 
Agency's intent to test the device and provide the manufacturer the 
opportunity to attend the test sessions and to comment on the specific 
test design and results.

[44 FR 17946, Mar. 23, 1979, as amended at 49 FR 18489, May 1, 1984]



Sec.  610.31  Vehicle tests for fuel economy and exhaust emissions.

    (a) The tests described in subpart D, E, or F may be conducted if 
existing data or other information are insufficient to support claims 
for a device in any of these areas:
    (1) Degree of improvement in fuel economy
    (2) Effect on exhaust emissions
    (3) Vehicle applicability
    (b) The Administrator may determine that, in certain cases, tests 
using engine dynamometers are adequate for determining the effect of a 
device. Examples of such cases are given below.
    (1) Long-term effects. In some cases, it may be necessary for the 
engine to operate for several thousand miles before the effectiveness 
can be adequately measured. In such cases an engine dynamometer will 
permit a less expensive and better controlled durability and economy 
test than one in which a vehicle must be driven on a durability route 
and then tested on a chassis dynamometer or test track.
    (2) Durability requirements. Aspects of engine durability can be 
efficiently determined using specialized engine testing rather than 
through durability mileage accumulation in a vehicle. A number of 
standard engine tests are presently used which can be incorporated into 
this requirement.
    (c) When in the judgment of the Administrator a device cannot 
satisfactorily be evaluated using either dynamometer or track versions 
of the City Fuel Economy Test and the Highway

[[Page 990]]

Fuel Economy Test, the Administrator will select or design other 
procedures.



Sec.  610.32  Test fleet selection.

    (a) The composition and size of the test fleet will be determined by 
the Administrator. In a device evaluation program initiated at the 
request of the FTC, the composition and size of the test fleet will be 
determined by the Administrator in consultation with the FTC.
    (b) The goal of the test fleet selection will be the provision of a 
data base adequate to give the Administrator reasonable confidence in 
the conclusions to be reached.
    (c) Once the number of vehicles to be tested has been determined, 
the Administrator will specify the test fleet makeup by make, model, 
model year, engine displacement and carburetor, transmission type, and 
such other factors as he may deem relevant to the testing program.



Sec.  610.33  Durability tests.

    The Administrator may determine that a device under evaluation will 
require durability testing in addition to the basic evaluation testing 
for device effectiveness. This requirement may be necessary for several 
reasons:
    (a) A retrofit device manufacturer may claim that some mileage 
accumulation may be needed before the full effectiveness of the device 
can be obtained. If such claims are made, durability testing as 
described in subpart E may be performed. To determine whether the 
effectiveness change during the mileage accumulation is a function of 
the device or of the mileage accumulation alone, in some durability 
tests it may be necessary to run the mileage accumulation on vehicles 
with and without the device. Due to the high cost of durability testing 
and in particular of such duplicate testing, it will be used only where 
it is judged by the Administrator to be necessary.
    (b) A device may have a limited life expectancy or be such that it 
requires replacement or adjustment at a prescribed mileage interval. 
Confirmatory durability tests may be run to assess whether such mileage 
intervals are proper and effective.
    (c) A device may be suspected of having an adverse effect on the 
durability of the engine to which it is applied. After identification of 
a potential failure mode, durability tests may be conducted to 
investigate any changes in engine characteristics associated with that 
failure mode. Examples are valve problems, deterioration in spark plug 
life, increase in carburetor or combustion chamber deposits, or 
increased engine wear. If it is not possible to directly measure the 
change in the suspect characteristic, then a durability run may be made 
as described in subpart E, in which fuel economy and exhaust emissions 
are periodically checked during the accumulation of up to 15,000 miles.
    (d) A critical item which can influence fuel economy is vehicle 
maintenance. Any durability test program used in evaluation of the 
effectiveness of a fuel economy device will be designed to differentiate 
maintenance effects from the effect of the device. Any maintenance 
associated with the device operation will be rigidly controlled. If the 
maintenance appears to be a significant factor in the effectiveness of a 
device, then it may be necessary to run a control test on vehicles 
without the device installed where the same maintenance is performed to 
quantify any incremental effect of that maintenance.



Sec.  610.34  Special test conditions.

    If the Administrator determines that a device may have potentially 
detrimental effects on the operation of a vehicle when operated in 
ambient conditions outside the range specified in 40 CFR part 86, or if 
the device manufacturer claims a fuel economy improvement in such 
conditions, additional tests may be performed. These tests will 
determine whether the device will significantly limit the operational 
usefulness of the vehicle and will assess the claimed fuel economy 
benefit.
    (a) Extreme temperatures. As required by the Administrator, tests 
will be conducted at extreme ambient temperature conditions to determine 
the effect due to devices (e.g. engine heaters) for which fuel economy 
improvements at extreme temperatures are made. For other devices it may 
be necessary to

[[Page 991]]

determine whether the cold starting and driving capability of device-
equipped vehicles is affected sufficiently to make them dangerous, or 
whether fuel economy characteristics at extreme temperatures are 
significantly worse than before the device was installed.
    (b) High altitude. Devices for which specific claims of improved 
fuel economy at high altitude are made may be tested using the 
procedures in subpart D, at altitudes above 4000 feet. For other 
devices, testing at high altitude may be necessary for determining 
whether a device will make the vehicle less useful or efficient when 
operated at various altitudes. The Administrator will determine when 
such testing is required.



Sec.  610.35  Driveability and performance tests.

    If the Administrator determines that driveability and performance of 
a vehicle may be adversely affected by the use of a device, a number of 
automobiles to be determined by the Administrator will be subjected to 
the driveability and performance tests discussed in Sec. Sec.  610.62 
and 610.63, respectively.



                Subpart D_General Vehicle Test Procedures



Sec.  610.40  General.

    Two chassis dynamometer test procedures, the Federal Test Procedure 
and the Highway Fuel Economy Test will generally be used to evaluate the 
effectiveness of the devices supplemented by steady state or engine 
dynamometer tests where warranted. Under unusual circumstances, other 
test procedures, durability test procedures or special test procedures 
such as track versions of the City and Highway fuel economy tests may be 
used. These procedures are described in subparts E and F.



Sec.  610.41  Test configurations.

    (a) In order to measure the effectiveness of a retrofit device at 
least two, and in some cases, three vehicle configurations defined in 
Sec.  610.11 will be tested. Each vehicle will be tested at least twice 
in each configuration, as determined by the Administrator.
    (b) The first test configuration is a baseline configuration. In 
this configuration the baseline or unretrofitted vehicle emissions will 
be measured.
    (c) A second test configuration, an adjusted configuration, may be 
required at the discretion of the Administrator if a device requires 
both hardware and engine parameter modifications to achieve the fuel 
economy improvement. If, in the Administrator's judgment, based on a 
review of the available information, the combined effects of retrofit 
hardware installation and parametric adjustment could be substantially 
duplicated by parametric adjustment alone, then the Administrator may 
specify a second test, to evaluate such adjustment exclusive of the 
retrofit hardware.
    (d) The third series of tests, in the retrofitted configuration, 
will evaluate the full retrofit system installed on the vehicle.



Sec.  610.42  Fuel economy measurement.

    (a) Fuel consumption will be measured by:
    (1) The carbon balance method, or
    (2) Gravimetric or volumetric methods. In the gravimetric and 
volumetric methods, fuel consumption is determined by weighing the fuel 
source before and after a test, or by measuring the volume of fuel 
consumed during a test. Since the distance traveled during the tests is 
known, the fuel economy, in miles per gallon, can be calculated. 
Gravimetric and volumetric methods require the use of special test 
equipment in addition to the emissions measuring equipment.
    (b) The carbon balance procedure for measuring fuel consumption 
relates the carbon products in the exhaust to the amount of fuel burned 
during the test. This method will be the one used to measure fuel 
economy unless track or road tests are employed.
    (c) Three values of fuel economy will be reported: for city driving 
('75 FTP), for highway driving (HFET), and the combined city/highway 
value calculated according to this equation:

Sec.  610.43  Chassis dynamometer procedures.

    (a)(1) 1975 Federal Test Procedure. Vehicle exhaust emissions and 
fuel economy under urban driving conditions will be measured according 
to the Federal emission test procedure described in 40 CFR part 86, 
subpart B, which is known as the 1975 Federal Test Procedure ('75 FTP). 
However, the following modifications will be employed:
    (i) No evaporative emission loss, as specified by 40 CFR part 86 
need be measured (with the exception of devices modifying or 
disconnecting existing evaporative control devices in such a manner as 
would be expected to adversely affect their evaporative emission control 
performance).
    (ii) Vehicle preconditioning shall consist of operation of the 
vehicle through one (1) EPA Urban Dynamometer Driving Schedule. This 
preconditioning must be done at least 12 hours, but no earlier than 36 
hours before the emission test.
    (iii) While the test fuel must meet the specifications outlined in 
40 CFR part 86, fuel conditioning as specified for evaporative emission 
test procedures is not required.
    (b) Highway Fuel Economy Test. The test vehicle is fully warmed up 
at the start of the highway Fuel Economy Test which is ordinarily run 
immediately following the Federal Emission Test Procedure. The test 
procedure to be followed for generation of highway fuel economy data is 
that specified in Sec.  600.111.
    (c) Steady state tests. Constant speed, road load tests may be 
conducted to help give insight into operational differences and exhaust 
emission and fuel economy changes due to a retrofit device. Speeds 
between 0 (engine idling) and 60 mpg will be investigated, with a time 
period at each speed long enough to ensure that engine operation has 
stabilized.



                  Subpart E_Durability Test Procedures



Sec.  610.50  Test configurations.

    (a) In addition to the tuneup to manufacturer's specifications per 
Sec.  610.41, all vehicles in the durability fleet will have installed 
the following new parts: Air, oil, and fuel filters, spark plugs, 
points, condenser, rotor, distributor cap, PCV valve, and emission 
control devices such as vacuum control valves and EGR valves.
    (b) Vehicles included in the durability fleet will be subjected at 
zero device-miles to the same test sequence for fuel economy and exhaust 
emissions as specified in subpart D. Subsequently, they will be tested 
at 3,000 device-mile intervals, up to and including the final mileage 
point of 15,000 device-miles. Testing at these mileage points will be 
performed with the vehicle equipped with the full retrofit system.
    (c) After the 15,000-mile test the vehicle will be tuned as 
necessary and the device adjusted to the manufacturer's specifications 
as required. The fully restored retrofitted configuration will then be 
tested. The device will then be removed from the vehicle and the vehicle 
set to vehicle manufacturer's specifications. A tuned baseline test will 
then be conducted.



Sec.  610.51  Mileage accumulation procedure.

    (a) Except as otherwise provided in this part, the mileage 
accumulation procedure will be that provided in 40 CFR part 86. This 
mileage accumulation schedule, or a suitable alternate procedure 
approved by the Administrator, will be used.
    (b) Fuel used in the accumulation of mileage will be commercial fuel 
available in the retail market and shall conform to the requirements of 
40 CFR part 86 for mileage accumulation fuel.
    (1) The requirements of this paragraph may be modified by the 
Administrator when it is a fuel or fuel additive that is being tested.



Sec.  610.52  Maintenance.

    (a) Maintenance during the durability evaluation can best be 
considered in three separate categories:
    (1) Normal scheduled vehicle maintenance,
    (2) Unscheduled vehicle maintenance, and
    (3) Retrofit maintenance.
    (b) Normal scheduled vehicle maintenance is the periodic service 
specified in the original owner's manual supplied

[[Page 993]]

to the owner at the time of new vehicle purchase.
    (1) Normal periodic engine oil changes, vehicle lubrication, and oil 
filter changes, as specified in the original owner's manual, will be 
performed during durability mileage accumulation.
    (2) For purposes of this part, the following items of normally 
scheduled vehicle maintenance will not be performed during the 
durability mileage accumulation:
    (i) Normal tune-up items:
    (A) Spark plugs.
    (B) Condenser.
    (C) Rotor.
    (D) Distributor cap.
    (ii) Air Cleaner element.
    (iii) PCV Inspection.
    (iv) Dwell and timing check.
    (v) Charging circuit check.
    (3) Periodic maintenance items specified in the original owner's 
manual, other than those listed above, may be performed if found to be 
necessary by the Administrator.
    (c) Unscheduled maintenance. Because the vehicles used for 
durability evaluation in this program will probably have considerable 
mileage accumulation and unknown maintenance prior to inclusion in the 
program, it can be anticipated that certain vehicle and engine failures 
may occur, which may be unrelated to the retrofit device. Unscheduled 
maintenance will be performed only in those cases where a significant 
and obvious driveability problem has been reported by the driver of the 
vehicle.
    (1) Correction of the following problems will be made as soon as the 
problems occur:
    (i) Tire replacement (same size and type).
    (ii) Vehicle body repairs (remote from engine and retrofit).
    (iii) Windshield wipers.
    (iv) Fluid levels unrelated to retrofit.
    (v) Brakes.
    (vi) Hoses unrelated to retrofit.
    (vii) Belts unrelated to retrofit.
    (viii) Suspension failures.
    (ix) Wheel alignment.
    (x) Steering.
    (xi) Wheel bearings.
    (xii) Non-engine electrical system.
    (xiii) Drivetrain components (U-joints, axles, transmission 
adjustments, etc.)
    (2) Other unscheduled maintenance of the engine or drivetrain may be 
made as directed by the Administrator. Upon notification of a need for 
unscheduled maintenance, the Administrator may decide that before and 
after maintenance fuel economy tests are required.
    (d) Retrofit maintenance. Maintenance of the retrofit device will 
normally not be performed during the accumulation of durability mileage 
of 15,000 miles. However, certain retrofit devices may require periodic 
maintenance that is directly related to device function. An example is 
the periodic addition of fluid to the reservoir of a vapor injector. The 
Administrator will determine whether periodic maintenance will be 
allowed, based on his review of available information including the 
device manufacturer's maintenance instructions to the consumer.
    (e) A log of all maintenance shall be kept for every vehicle. These 
logs will be summarized in the final report by the Administrator.



                    Subpart F_Special Test Procedures



Sec.  610.60  Non-standard ambient conditions.

    (a) Extreme temperatures. For vehicles required to be tested at 
extreme temperatures, the test sequence described in Sec.  610.41 will 
be performed using either test track or dynamometer, in ambient 
temperatures outside the 60[deg] to 90[deg] range specified in Sec.  
610.64 as determined by the Administrator. The driveability tests 
described in Sec.  610.62 may also be performed at non-standard 
temperatures, as determined to be necessary by the Administrator.
    (b) High altitudes. Vehicles required to be tested at high altitudes 
will undergo the tests described in Sec.  610.43 if necessary, on either 
test track or dynamometer as determined by the Administrator. One test 
location, at an elevation of no less than 4000 feet, will be selected.



Sec.  610.61  Engine dynamometer tests.

    The Administrator will choose a test procedure or procedures from 
various

[[Page 994]]

engine dynamometer durability test procedures used by research 
organizations in government, the oil industry, engine manufacturing 
companies, and independent laboratories.



Sec.  610.62  Driveability tests.

    Driveability assessment (at normal ambient temperatures) of the 
baseline configuration, of the adjusted configuration (if required by 
the Administrator), and of the fully retrofitted configuration may be 
conducted at zero device-miles for all vehicles included in the 
durability fleet, and at approximately zero device-miles at low ambient 
temperatures (0 [deg]F-20 [deg]F). Driveability evaluation procedures 
will be provided by the Administrator when necessary.



Sec.  610.63  Performance tests.

    The effect of a device on a vehicle's performance will be determined 
by performing wide-open-throttle 0 to 60 mph acceleration tests (at 
normal ambient temperatures) on the baseline vehicle configuration, on 
the adjusted configuration (if required), and on the fully retrofitted 
configuration. Tests will be conducted on a dry, level, smooth-surfaced 
test track, with appropriate speed-time measuring equipment, on as many 
vehicles as determined to be necessary.



Sec.  610.64  Track test procedures.

    (a) Cases may arise where it will be necessary to evaluate the fuel 
economy effects of a retrofit device on a test track, because the effect 
of the device cannot be adequately tested using the chassis dynamometer 
procedures. (An obvious example is a device that changes the aerodynamic 
drag of the test vehicle.) In such cases, testing will be performed on a 
dry, level, smooth-surfaced test track for such dimensions that the 
speeds required by the city and highway fuel economy tests may be safely 
achieved.
    (1) Because aerodynamic drag is not a linear function of velocity, 
it will be necessary to limit testing to times when the wind velocity is 
less than 5 mph, with gusts less than 10 mph.
    (2) Testing will also be limited to ambient temperatures between 
60[deg] and 90 [deg]F, and to times when the ambient temperature remains 
reasonably constant during individual tests. Temperature differences 
between tests of baseline and retrofit configurations will also be 
minimized.
    (3) Exhaust emissions will not be measured during track testing.
    (4) Fuel economy of a vehicle running on a track will be measured 
using either a volumetric or gravimetric procedure approved by the 
Administrator.
    (5) Vehicle speed and distance will be measured with a ``fifth 
wheel'' type of device. Suitable apparatus will be used to generate a 
permanent record (strip chart recorder, etc.) of the vehicle speed 
versus time.
    (b) City fuel economy test. Although essentially the same procedures 
will be used for track testing as for dynamometer testing, some 
modifications will be necessary to insure safe operation of the test 
vehicle and to adjust to the requirements of track testing.
    (1) An assistant to the driver will be necessary to steer the 
vehicle, so that the driver will not be distracted from following the 
speed-time schedules used in the Federal test procedure.
    (2) The test vehicle will be preconditioned within the same time 
constraints given in Sec.  610.43(a)(1)(ii). Preconditioning may take 
place either on the track or on a dynamometer. The 12-hour soak after 
preconditioning will take place in an area where the ambient temperature 
will remain within the 60[deg] to 90 [deg]F range, indoors, if 
necessary.
    (3) The vehicle will be transported to the test track without being 
started. If the distance from soak area to track is no greater than one-
quarter mile, then the vehicle may be pushed or towed to the track. 
Otherwise the vehicle must be transported by truck or trailer.
    (4) Fuel economy will be determined by either a gravimetric or 
volumetric method.
    (c) Highway fuel economy test. The highway test will follow the city 
fuel economy test in the same manner as in dynamometer tests (Sec.  
610.43(b)). Fuel economy will be measured by gravimetric or volumetric 
methods.
    (d) Steady state tests. Steady state tests on the track will be run 
in the same manner as on the dynamometer

[[Page 995]]

except that fuel economy will be measured by gravimetric or volumetric 
methods.



Sec.  610.65  Other test procedures.

    The Administrator may, pursuant to Sec.  610.31(c), choose a test 
procedure or procedures from those used by research organizations in 
government, the oil industry, engine manufacturing companies, and 
independent laboratories. If none of these is deemed suitable, the 
Administrator may, in consultation with the party requesting the test, 
design a dynamometer, track or road test to measure the effects of the 
device.
