TITLE 40--PROTECTION OF ENVIRONMENT
CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
PART 136_GUIDELINES ESTABLISHING TEST PROCEDURES FOR THE ANALYSIS OF POLLUTANTS--Table of Contents
Sec. 136.3 Identification of test procedures.
(a) Parameters or pollutants, for which methods are approved, are
listed together with test procedure descriptions and references in
Tables IA, IB, IC, ID, IE, and IF. The full text of the referenced test
procedures are incorporated by reference into Tables IA, IB, IC, ID, IE,
and IF. The incorporation by reference of these documents, as specified
in paragraph (b) of this section, was approved by the Director of the
Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.
Copies of the documents may be obtained from the sources listed in
paragraph (b) of
[[Page 6]]
this section. Information regarding obtaining these documents can be
obtained from the EPA Office of Water Statistics and Analytical Support
Branch at 202-566-1000. Documents may be inspected at EPA's Water
Docket, EPA West, 1301 Constitution Avenue, NW., Room B135, Washington,
DC (Telephone: 202-566-2426); or at the Office of the Federal Register,
800 North Capitol Street, NW., Suite 700, Washington, DC. These test
procedures are incorporated as they exist on the day of approval and a
notice of anys change in these test procedures will be published in the
Federal Register. The discharge parameter values for which reports are
required must be determined by one of the standard analytical test
procedures incorporated by reference and described in Tables IA, IB, IC,
IE, and IF, or by any alternate test procedure which has been approved
by the Administrator under the provisions of paragraph (d) of this
section and Sec. Sec. 136.4 and 136.5. Under certain circumstances
(paragraph (b) or (c) of this section or 40 CFR 401.13) other test
procedures may be more advantageous when such other test procedures have
been previously approved by the Regional Administrator of the Region in
which the discharge will occur, and providing the Director of the State
in which such discharge will occur does not object to the use of such
alternate test procedure.

\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 to Table 1B Note 4: 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.

manual distillation will be required to resolve any controversies.

\12\ Carbonaceous biochemical oxygen demand (CBOD5) must not be confused with the traditional BOD5 test method which measures ``total BOD''. The addition of the nitrification inhibitor is not
a procedural option, but must be included to report the CBOD5 parameter. A discharger whose permit requires reporting the traditional BOD5 may not use a nitrification inhibitor in the
procedure for reporting the results. Only when a discharger's permit specifically states CBOD5 is required can the permittee report data using a nitrification inhibitor.

\20\ After the manual distillation is completed, the autoanalyzer manifolds in EPA Methods 335.3 (cyanide) or 420.2 (phenols) are simplified by connecting the re-sample line directly to the
sampler. When using the manifold setup shown in Method 335.3, the buffer 6.2 should be replaced with the buffer 7.6 found in Method 335.2.

\29\ 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.

\7\ Each Analyst must make an initial, one-time demonstration of their ability to generate acceptable precision and accuracy with Methods 601-603, 624,
625, 1624B, and 1625B (See Appendix A of this Part 136) in accordance with procedures each in Section 8.2 of each of these Methods. Additionally, each
laboratory, on an on-going basis must spike and analyze 10% (5% for Methods 624 and 625 and 100% for methods 1624B and 1625B) of all samples to
monitor and evaluate laboratory data quality in accordance with Sections 8.3 and 8.4 of these Methods. When the recovery of any parameter falls
outside the warning limits, the analytical results for that parameter in the unspiked sample are suspect and cannot be reported to demonstrate
regulatory compliance.

(c) Under certain circumstances the Regional Administrator or the
Director in the Region or State where the discharge will occur may
determine for a particular discharge that additional parameters or
pollutants must be reported. Under such circumstances, additional test
procedures for analysis of pollutants may be specified by the Regional
Administrator, or the Director upon the recommendation of the Director
of the Environmental Monitoring Systems Laboratory--Cincinnati.
(d) Under certain circumstances, the Administrator may approve, upon
recommendation by the Director, Environmental Monitoring Systems
Laboratory--Cincinnati, additional alternate test procedures for
nationwide use.
(e) Sample preservation procedures, container materials, and maximum

Table II Notes
\1\ Polyethylene (P) or glass (G). For microbiology, plastic sample containers must be made of sterilizable
materials (polypropylene or other autoclavable plastic).
2 Sample preservation should be performed immediately upon sample collection. For composite chemical samples
each aliquot should be preserved at the time of collection. When use of an automated sampler makes it
impossible to preserve each aliquot, then chemical samples may be preserved by maintaining at 4[deg]C until
compositing and sample splitting is completed.
3 When any sample is to be shipped by common carrier or sent through the United States Mails, it must comply
with the Department of Transportation Hazardous Materials Regulations (49 CFR part 172). The person offering
such material for transportation is responsible for ensuring such compliance. For the preservation
requirements of Table II, the Office of Hazardous Materials, Materials Transportation Bureau, Department of
Transportation has determined that the Hazardous Materials Regulations do not apply to the following
materials: Hydrochloric acid (HCl) in water solutions at concentrations of 0.04% by weight or less (pH about
1.96 or greater); Nitric acid (HNO3) in water solutions at concentrations of 0.15% by weight or less (pH about
1.62 or greater); Sulfuric acid (H2SO4) in water solutions at concentrations of 0.35% by weight or less (pH
about 1.15 or greater); and Sodium hydroxide (NaOH) in water solutions at concentrations of 0.080% by weight
or less (pH about 12.30 or less).
\4\ Samples should be analyzed as soon as possible after collection. The times listed are the maximum times that
samples may be held before analysis and still be considered valid. Samples may be held for longer periods only
if the permittee, or monitoring laboratory, has data on file to show that for the specific types of samples
under study, the analytes are stable for the longer time, and has received a variance from the Regional
Administrator under Sec. 136.3(e). Some samples may not be stable for the maximum time period given in the
table. A permittee, or monitoring laboratory, is obligated to hold the sample for a shorter time if knowledge
exists to show that this is necessary to maintain sample stability. See Sec. 136.3(e) for details. The term
``analyze immediately'' usually means within 15 minutes or less of sample collection.
5 Should only be used in the presence of residual chlorine.
6 Maximum holding time is 24 hours when sulfide is present. Optionally all samples may be tested with lead
acetate paper before pH adjustments in order to determine if sulfide is present. If sulfide is present, it can
be removed by the addition of cadmium nitrate powder until a negative spot test is obtained. The sample is
filtered and then NaOH is added to pH 12.
7 Samples should be filtered immediately on-site before adding preservative for dissolved metals.
8 Guidance applies to samples to be analyzed by GC, LC, or GC/MS for specific compounds.
9 Sample receiving no pH adjustment must be analyzed within seven days of sampling.
10 The pH adjustment is not required if acrolein will not be measured. Samples for acrolein receiving no pH
adjustment must be analyzed within 3 days of sampling.
11 When the extractable analytes of concern fall within a single chemical category, the specified preservative
and maximum holding times should be observed for optimum safeguard of sample integrity. When the analytes of
concern fall within two or more chemical categories, the sample may be preserved by cooling to 4[deg]C,
reducing residual chlorine with 0.008% sodium thiosulfate, storing in the dark, and adjusting the pH to 6-9;
samples preserved in this manner may be held for seven days before extraction and for forty days after
extraction. Exceptions to this optional preservation and holding time procedure are noted in footnote 5 (re
the requirement for thiosulfate reduction of residual chlorine), and footnotes 12, 13 (re the analysis of
benzidine).
12 If 1,2-diphenylhydrazine is likely to be present, adjust the pH of the sample to 4.0+-0.2 to prevent
rearrangement to benzidine.
13 Extracts may be stored up to 7 days before analysis if storage is conducted under an inert (oxidant-free)
atmosphere.
14 For the analysis of diphenylnitrosamine, add 0.008% Na2S2O3 and adjust pH to 7-10 with NaOH within 24 hours
of sampling.
15 The pH adjustment may be performed upon receipt at the laboratory and may be omitted if the samples are
extracted within 72 hours of collection. For the analysis of aldrin, add 0.008% Na2S2O3.

\16\ Sufficient ice should be placed with the samples in the shipping container to ensure that ice is still
present when the samples arrive at the laboratory. However, even if ice is present when the samples arrive, it
is necessary to immediately measure the temperature of the samples and confirm that the 4C temperature maximum
has not been exceeded. In the isolated cases where it can be documented that this holding temperature can not
be met, the permittee can be given the option of on-site testing or can request a variance. The request for a
variance should include supportive data which show that the toxicity of the effluent samples is not reduced
because of the increased holding temperature.
\17\ Samples collected for the determination of trace level mercury (100 ng/L) using EPA Method 1631 must be
collected in tightly-capped fluoropolymer or glass bottles and preserved with BrCl or HCl solution within 48
hours of sample collection. The time to preservation may be extended to 28 days if a sample is oxidized in the
sample bottle. Samples collected for dissolved trace level mercury should be filtered in the laboratory.
However, if circumstances prevent overnight shipment, samples should be filtered in a designated clean area in
the field in accordance with procedures given in Method 1669. Samples that have been collected for
determination of total or dissolved trace level mercury must be analyzed within 90 days of sample collection.
