AGENCY: Environmental Protection
Agency (EPA).
ACTION: Final rule.
SUMMARY: This final rule revises
wastewater and drinking water
regulations to include updated versions
of test procedures (i.e., analytical
methods) for the determination of
chemical, radiological, and
microbiological pollutants and
contaminants in wastewater and
drinking water. The updated versions of
analytical methods have been published
by one or more of the following
organizations: ASTM International
(ASTM; formerly the American Society
for Testing and Materials), United States
Geological Survey (USGS), United
States Department of Energy (DOE),
American Public Health Association
(APHA), American Water Works
Association (AWWA), and Water
Environment Federation (WEF).
Previously approved versions of the
methods remain approved.
DATES: This final rule is effective on
November 22, 2002. The incorporation
by reference of the publications listed in
today's rule is approved by the Director
of the Federal Register as of November
22, 2002. For judicial review purposes,
this final rule is promulgated as of 1
p.m. (Eastern time) on November 6,
2002 as provided at 40 CFR 23.2 and
23.7.
ADDRESSES: The record for this
rulemaking has been established under
docket number W—99—21. Copies of the
public comments received, EPA
responses, and all other supporting
documents (including references
included in this document) are available
for review at the U.S. Environmental
Protection Agency, Water Docket, on
Monday through Friday, excluding
Federal holidays, between 9 a.m. and
3:30 p.m. Eastern Time. Please contact
the Water Docket for an appointment.
From August 12, 2002 through August
26, 2002, the Water Docket will be
closed. Beginning on August 27, 2002,
the Water Docket will be located at EPA

SUPPLEMENTARY INFORMATION:
Potentially Regulated Entities
A. Clean Water Act
EPA Regions, as well as States,
Territories, and Tribes, are authorized to
implement the National Pollutant
Discharge Elimination System (NPDES)
program, issue permits that comply with
the technology-based and water quality-
based requirements- of the Clean Water
Act. In doing so, the NPDES permitting
authorities, including authorized States,
Territories, and Tribes, make a number
of discretionary choices associated with
permit writing, including the selection
of pollutants to be measured and, in
.many cases, limited, in permits. If EPA
has "approved" (i.e., promulgated
through rulemaking) standardized
testing procedures for a given pollutant,
the NPDES permit must specify that
analysis of that pollutant be conducted
in accordance with one of the approved
testing procedures or an approved
alternate test procedure. Permitting
authorities may, at their discretion,
require the use of any method approved
at 40 CFR part 136 in the permits they
issue. Therefore, NPDES permits may
incorporate the testing procedures in
today's rulemaking so dischargers with
NPDES permits could be affected by the
standardization of testing procedures in
this rulemaking. In addition, States,
Territories, or authorized Tribes
responsible for providing certification of
Federal licenses under Clean Water Act
section 401, could be regulated by
today's rulemaking because these
organizations are directed to use the
standardized testing procedures.

ultimately be regulated include:

B. Safe Drinking Water Act
Public water systems are the regulated
entities required to conduct analyses to
measure for contaminants in water
samples. However, EPA Regions, as well
as States, and Tribal governments with
primacy to administer the regulatory
program for public water systems under
the Safe Drinking Water Act, sometimes
conduct analyses to measure for
contaminants in water samples. If EPA
has established a maximum
contaminant level ("MCL") for a given
drinking water contaminant, the Agency
also approves (i.e.. promulgates through
rulemaking) standardized testing
procedures for analysis of the
contaminant. Once EPA standardizes
such test procedures, analysis using a
standard (or approved alternate test
procedures) is required. Public water
systems required to test water samples
must use one of the approved
standardized test procedures. Categories
and entities that may ultimately be
regulated include:

I. Legal Authorities
A. Clean Water Act
This regulation is promulgated under
the authority of sections 301, 304(h),
307, and 501(a) of the Clean Water Act
(CWA), 33 U.S.C. 1311, 1314(h), 1317,
1361(a) (the "Act"). Section 301 of the
Act prohibits the discharge of any
pollutant into navigable waters unless '
the discharge complies with a National
Pollutant Discharge Elimination System.
(NPDES) permit, issued under section
402 of the Act. Section 304(h) of the Act
requires the EPA Administrator to
"promulgate guidelines establishing test
procedures for the analysis of pollutants
that shall include the factors which
must be provided in any certification
pursuant to section 401 of this Act or
permit applications pursuant to section
402 of this Act." Section 501(a) of the
Act authorizes the Administrator to
"prescribe such regulations as are
necessary to carry out his functions
under this Act." EPA publishes CWA
analytical method regulations at 40 CFR
Part 136. The Administrator also has
made these test procedures applicable to
monitoring and reporting of NPDES
permits (40 CFR part 122, §§ 122.21,
122.41,122:44, and 123.25), and to
implementation of the pretreatment
standard^ issued under section 307 of
the Act (<40 CFR part 403, §§ 403.10 and
403.12).'
B. Safe Qrinking Water Act
The Safe Drinking Water Act (SDWA),
as amended in 1996, requires EPA to
promulgate national primary drinking
water regulations (NPDWRs) that
specify rhaximum contaminant levels
(MCLs) or treatment techniques for
drinking water contaminants (SDWA
section 1412 (42 U.S.C. 300g-l)).
NPDWRs apply to public water systems
pursuant to SDWA section 1401(1)(A)
(42 U.S.C. 300f(l)(A)). According to
-SDWA section 1401(l)(D), NPDWRs
include "criteria and procedures to
assure a supply of drinking water which
dependably complies with such
maximum contaminant levels; including
accepted methods for quality control
and testing procedures * * *" (42
U.S.C. 300f(l)(D)). In addition, SDWA
section 1445 (a) authorizes the
Administrator to establish regulations
for monitoring to assist in determining
whether persons are acting in
compliance with the requirements of the
SDWA (42 U.S.C. 300J-4). EPA's
promulgation of analytical methods is
authorized under these sections of the
SDWA ajs well as the general rulemaking
authority in SDWA section 1450(a), (42
U.S.C. 300j-9(a)).
II. Regulatory Background and History
EPA has promulgated analytical
methods for all currently regulated
wastewa'ter and drinking water
pollutants and contaminants. For most
contaminants, EPA has promulgated
regulations approving the use of more
than one standardized analytical
method, and regulated entities may use
any one of these approved methods for
determining compliance with an MCL,
an NPDES permit or another monitoring
requirement. After any regulation is
published, EPA may amend the
regulations to approve additional
methods or modifications to existing
approved methods, or withdraw
approved methods that become
•obsolete.
On January 16, 2001, EPA published
a direct final rule that was to approve
many updated methods published by
non-EPA organizations for use in
wastewater and drinking wat^r
compliance monitoring (66 FR 3466-
3497). On the same day, EPA published
a companion proposal that proposed
approval of all methods in the direct
final rule methods (66 FR 3526-3527).
The proposal was to serve as the basis
for a final rule if the direct final was
withdrawn due to adverse comments.
Because adverse comments were
received from one commenter, EPA
withdrew the direct final rule on May
15, 2001 (66 FR 26795) and deferred
final action in order to respond to those
comments. Today's rulemaking
constitutes EPA's final action on the
proposed rule.
in. Summary of Final Rule
A. This rule amends the regulations at
40 CFR part 136 to:
(1) Allow the use of 19 updated
methods published by the ASTM
International (ASTM; formerly the
American Society for Testing and
Materials) in the 1999 Annual Book of
ASTM Standards, Vols. 11.01 and 11.02.
(2) Allow the use of 189 updated
methods published by the Standard
Methods Committee in Standard
Methods for the Examination of Water
and Wastewater, 19th edition, 1995, and
20th edition, 1998.
(3) Allow the use of 22 methods
published by the United States
Geological Survey (USGS) in open file
reports and method compendiums.
(4) Correct minor editorial errors and
update method source references.

40 CFR Part 141 to:
(1) Allow the use of 12 updated
methods published in the 1999 Anniml
Book of ASTM Standards, Vols. 11.01
and 11.02.
(2) Allow the use of 62 updated
methods published by the Standard

Methods for the Examination of Water
and Wastewater, 20th edition, 1998.
(3) Correct update method source
references.
IV. Changes From the January 16, 2001
Rule Proposal
A. Editorial Corrections
Standard Methods 6220 B, 6230 B,
and 6200 C were correctly specified in
the rule text of the January, 16, 2001,
direct final rule, but they were
incorrectly referenced in Table 3 (64 FR
3470) of the preamble to that rule.
Corrections to the preamble errors are
noted as follows:

Edits to 40.CFR Part 136
Two errors in the rule section of the
January 2001 direct final rule at 40 CFR
part 136.3 are corrected in today's rule
as follows:
(1) A portion of a citation originally
intended as a placeholder in footnote 45
to Table IB was inadvertently included.
This citation is corrected to reference
the correct USGS document number.
"98-xxx" is changed to "00-170."
(2) Footnote 44 to Table IB is
renumbered, and a new footnote 44 is
added to conform with a final rule that
was published on December 30,1999
(64 FR 73414). The December 1999 rule
renumbered footnote 44 to footnote 51,
and amended footnote 44 to specify
information about a cyanide method
that was the subject of the December
1999 rule. The direct final rule
inadvertently overlooked these 1999
amendments.
Edits to 40 CFR Part 141
A commenter noted an error and EPA
noted an omission in the references to
methods at 40 CFR part 141.21 for
determination of E coli. in drinking
water. The error and omission are
addressed, in today's rule, by revising
40 CFR 141.21 as follows:
(1) Footnote 1 to the table in
paragraph (f)(3), paragraphs (f)(6)(i),
(f)(6)(ii) and (f)(8) are revised to clarify
instructions for the determining E coli.
A commenter noted that the E coli.
methods in the 19th and 20th editions
of Standard Methods describe or
reference procedures differently than
the 18th edition version of these
methods. These differences are editorial,
not substantive, and all three versions of
these methods provide equivalent
results. Today's correction adds
clarifying language to make the
equivalency of the 18th, 19th and 20th
edition versions of these E coli. methods
more apparent.
(2) Sentence 6 of paragraph (f)(5) is
revised to add a citation to the 20th
edition of Standard Methods that was
inadvertently omitted in the January
2001 direct final rule. The Agency's
intent in the January 16, 2001 direct
-final rulemaking was and is to allow use
of more recent editions of Standard
Methods, such as the 20th edition.
B. Additional Technical Edits to 40 CFR
Part 136.3
A commenter noted several editorial
errors in the current 40 CFR part 136.3
tables. EPA is correcting these errors in
today's rule. Correction of these errors is
not a substantive change to EPA
regulations. These are simple editorial
corrections that improve the clarity and
accuracy of the regulations.
Edits to Table 1C
(1) A typographical error in the listing
of the method for parameter 3 (acrolein)
is corrected. Method "604" is changed
to "624."
(2) An incorrect reference to Method
610 for parameter 4, acrylonitrile, is
removed. Method 610 is not applicable
to determinations of acrylonitrile.
(3) An incorrect reference to Method
6410B for parameter 22, carbon
tetrachloride is removed. Method 6410B
is not applicable to determinations of
carbon tetrachloride.
(4) A misspelling of the analyte listing
for parameter 27 is corrected,
"chloraform" is changed to
"chloroform." Also, a missing number
in the note specified in the "Other"
column was inadvertently omitted,
"Note, p. 130." is changed to "Note 3,
p. 130."
(5) A missing reference to footnote 5
is added to parameter 82, N-
Nitrosodimethylamine, and removed for
parameters 83 and 103, N-Nitrosodi-n-
propylainine, and 2,3,7,3-
tetrachlorodibenzo-p-dioxin,
respectively. Footnote 5 expands the
analytical scope of Method 625 to
include additional parameters.
However, the annotation of these
parameters in Table 1C omitted
parameter 82, and should not have
included parameters 83 and 103.
(6) A typographical error in the
analyte listing for parameter 87 is
corrected, 2,2'-oxybis(-l-chloropropane)
is changed to 2,2'-oxybis(l-
chloropropane). In addition, an
alternative analyte name, bis(2-
chloroisopropyl) ether, is added for
parameter 87. These changes conform
the CFR listing of parameter 87 with the
dual, equivalent name designation of
this parameter in the methods (EPA
Methods 611, 625 and 1625B) approved
for compliance determinations of
parameter 87.
(7) A typographical error in the
reference to the compliance method for
. parameter 105, tetrachloroethene, is
corrected. Method "6410 B [18th, 19th]"
is changed to "6210 B [18th, 19th]."
Method 6410 B is not applicable to
determinations of tetrachloroethene.
(8) An incorrect reference to Method
"16255a" for parameter 103 (2,3,7,8-
tetrachlorodibenzo-p-dioxin) is removed
along with the superfluous footnote 5a
to table 1C. Method 1625 is not
applicable to determinations of this
parameter.
Edits to Table ID
A typographical error in the analytt;
listing for parameter 11 is corroded. "5-
BHC" is changed to "y-BHC."
Edits to Tables IB and 1C
To correctly specify the approved
revision of listed EPA methods, a
revision letter is added to the muthcul
-------
Federal Register/Vol. 67, No. 205/Wednesday, October 23, 2002/Rules and Regulations 65223
listings for EPA methods in Table 1C.
References to EPA methods "1613,"
"1624" and "1625" are changed to
"1613B," "1624B" and "1625B,"
respectively. In Table IB, EPA Method
"1631" is changed to "1631C."
V. Response to Comments
EPA proposed the method updates in
today's rule on January 16, 2001 (66 FR
3526). The public comment period
closed on March 19, 2001. EPA received
comments from one commenter. A
discussion of the significant comments
follows. A complete copy of the
comments and EPA's responses are
included in the Docket for today's final
rule.
A. Approving Multiple Editions of
Standard Methods
The commenter stated that approval
of multiple editions of Standard
Methods is a new requirement and an
added burden to the regulatory
authorities that must keep track of all
approved methods. EPA disagrees that
tracking multiple editions of Standard
Methods is a new requirement or
unduly burdensome. The Agency
currently cites more than one edition of
the same method, e.g. footnote 4 to the
table of inorganic methods at 40 CFR
141.23 allows use of either the 18th or
19th edition versions of all the Standard
Methods listed in the table. For this
reason, the Agency always cites an
approved method by both method
number and date (or edition) of
publication to avoid confusion about
which versions are approved, and to
allow incorporation of the method by
reference in the CFR in lieu of
publication of the entire method in the
CFR. This citation policy means that
existing State databases would be
designed to accommodate the edition as
well as the number of an approved
method so that multiple versions of an
approved method can be tracked.
EPA recognizes that there'are
tradeoffs between the current approach
of allowing use of several versions of a
test method, and the suggested revision
(received in a comment) to allow only
the most recent version of that method.
Allowing use of only the 20th edition of
Standard Methods may have more
consequences than just the purchase of
the 20th edition book. A laboratory may
routinely use only a few methods that
are published in Standard Methods, and
these may be methods that have been
reprinted in the 20th edition with no
editorial or technical changes. Under
the suggested revision to allow use of
only the 20th edition of Standard
Methods, a laboratory may be required
to update method citations in existing
quality assurance manuals; and
laboratory standard operating
procedures as well as provide analysts
with a copy of the 20th edition version
of the method even when the methods
have not changed from previous
editions;
Furthermore, withdrawal of previous
editions tof Standard Methods was not
proposed for public comment in the
January 2001 rule, and the suggestion to
allow use of only the 20th edition of
Standard Methods is outside the scope
of today'is regulatory amendments.
Public comment on previous proposals
to withdraw older versions of methods,
indicated that most laboratories prefer
the flexibility to use these versions if the
methods-have not changed significantly
in new editions of the manuals. Thus,
EPA continues to allow use of older
editions 'of Standard Methods.
B. Technical Differences Between
Methods
The cqmmenter suggested that some
methods in the 18th edition of Standard
Methods, are obsolete because of
technical and editorial updates in newer
editions. EPA disagrees that the
methods1 in the 18th edition of Standard
Methods approved in today's rule are
obsolete.
The methods approved by today's rule
are technically equivalent to previously
approved versions. Only methods using
time-testjed technologies are approved
by today's rule. For the purposes of
compliance monitoring, however, none
of these methods are obsolete and all
methods provide the necessary
technical information. Therefore, EPA
believes the use of previously approved
editions !of Standard Methods continues
to be appropriate.
C. Withdrawing Methods That Use
Older Technology
The cqmmenter suggested
colorime!tric-methods for trace metals
analysis, with the exception of
hexavalent chromium, be dropped from
the list of approved methods at 40 CFR
part 136; Table IB, arguing that these
methods; are obsolete. The commenter
stated that many of these methods list
interferences not encountered by atomic
absorption, atomic emission, or mass
spectroriietry techniques. The
commenter also stated that many of
these methods also increase the amount
of hazardous waste generated in the
laboratory and that the detection limits
attained by the colorimetric methods
may not;be low enough to meet permit
requirements. EPA disagrees for several
reasons. |
Coloripietric metals methods have
been in use a long time, and explain
how to handle the analytical difficulties
noted by the commenter. Although
many of the colorimetric methods have
the potential to generate more laboratory
wastes than some newer methods, these
methods produce acceptable
compliance monitoring information,
and the commenter did not provide any
data to demonstrate otherwise.
Colorimetric methods often provide a
low-cost alternative to high energy
analysis methods that have high labor
and equipment costs. Finally,
withdrawal of these methods was not
proposed for public comment and is
outside the scope of today's
amendments.
D. Digestion Preceding Sample Analysis
The commenter noted that 40 CFR
part 136.3, Table IB, parameter 31,
referring to total Kjeldahl nitrogen
(TKN), specifies "digestion and
distillation followed by" one of several
new techniques. The commenter asked
if "digestion and distillation followed
by" means that digestion and
distillation are required prior to analysis
of a sample for NPDES compliance
monitoring. EPA requires the use of
separate digestion and distillation
procedures prior to TKN analysis by
certain methods, as specified in Table
IB. "Digestion and distillation followed
by," in the context of Table IB, requires
the use of one of the listed digestion and
distillation procedures for the Titration,
Nesslerization and Electrode test
methods. Today's rule reformats Table
IB with appropriate indentation to
reflect this requirement more clearly.
Other TKN methods explicitly require
alternate sample preparation
procedures, such as the semiautomated
block digestion (e.g., EPA Method
351.2). For these methods, TKN analysis
does not require the use the digestion
and distillation procedures discussed in
the preceding paragraph, because the
alternate sample preparation procedures
will provide the desired results.
E. Metals Methods in 20th Edition of
Standard Methods
The commenter inquired about the
status of the graphite furnace and flame
atomic absorption methods for metals
analyses (GFAA and FLAA,
respectively) that were revised in the
20th edition of Standard Methods, but
not proposed for approval in the January
16, 2001 rule. The commenter
recommended that EPA either approve
or not approve all versions (18th, 19th
and 20th edition) and not split approval
of these methods by edition number.
EPA did not propose, and today's rule
does not approve, the 20th Edition
versions of Methods 3111B, 3111D,
-------
65224 Federal Register/Vol. 67, No. 205/Wednesday, October 23, 2002/Rules and Regulations
3112 B, 3113 B and 3114 B, which
include the GFAA and FLAA methods
noted by the commenter. These versions
of the five methods are not acceptable
because the method performance
requirements specified in the 20th
edition are not equivalent or better than
in the 18th and 19th edition versions of
these methods. The 20th edition of
Standard Methods introduces less
stringent quality control (QC)
acceptance criteria (in Section 3020 of
each method) than in the older versions.
Specifically, the 18th and 19th edition
versions specify that a recovery of a
chock standard outside the range of 95%
to 105% suggests a potential problem,
and a recovery outside the range of 90%
to 110% indicates that the system is out
of control. The 20th edition weakened
and increased these limits to 90% to
100% and 80% to 120%, respectively.
The editors of Standard Methods did
not provide a basis for weakening the
QC requirements in these methods, and
they did not suggest applying these less
stringent criteria to previous editions of
the methods.
VL Administrative Requirements . .
A. Executive Order 12866: Regulatory
Planning and Review
Under Executive Order 12866 (58 FR
51735; October 4,1993), the Agency
must determine whether the regulatory
action is "significant" and, therefore,
subject to OMB review and the
requirements of the Executive Order.
The Order defines "significant
regulatory action" as one that is likely
to result in a rule that may:
(1) Have an annual effect on the
economy of $100 million or more, or
adversely affect in a material way the
economy, a sector of the economy,
productivity, competition, jobs, the
environment, public health or safety, or
State, local, or Tribal governments or
communities;
(2) Create a serious inconsistency or
otherwise interfere with an action taken
or planned by another agency;
(3) Materially alter the budgetary
impact of entitlements, grants, user fees,
or loan programs or the rights and
obligations of recipients thereof; or
(4) Raise novel legal or policy issues
arising out of legal mandates, the
President's priorities, or the principles
set forth in the Executive Order.
It has been determined that this rule
is not a "significant regulatory action"
under the terms of Executive Order
12866 and is therefore not subject to
OMB review.
B. Regulatory Flexibility Act (RFA), as
Amended by the Small Business
Regulatory Enforcement Fairness Act of
1996 (SBREFA), 5 U.S.C. 601 et. seq.
The RFA generally requires an agency
to prepare a regulatory flexibility
analysis of any rule subject to notice
and comment rulemaking requirements
under the Administrative Procedure Act
or any other statute unless the agency
certifies that the rule will not have a
significant economic impact on a
substantial number of small entities.
Small entities include small businesses,
small organizations, and small
governmental jurisdictions.
The RFA provides default definitions
for each type of small entity. It also
authorizes an agency to use alternative
definitions for each category of small
entity, "which are appropriate to the
activities of the agency" after proposing
the alternative definition(s) in the
Federal Register and taking comment (5
U.S.C. 601(3)-(5).) In addition to the
above, to establish an alternative small
business definition, agencies must
consult with the Small Business
Administration's (SBA) Chief Counsel
for Advocacy.
For purposes of assessing the impacts
of today's rule on small entities under
the SDWA, EPA considered small
entities to be public water systems
serving fewer than 10,000 persons. This
is the cut-off level specified by Congress
in the 1996 Amendments to the SDWA
for small system flexibility provisions.
In accordance with the RFA
requirements, EPA proposed using this
alternative definition in the Federal
Register (63 FR 7620, February 13,
1998), requested comment, consulted
with the SBA, and expressed its
intention to use the alternative
definition for all future drinking water
regulations in the Consumer Confidence
Reports regulation (63 FR 44511, August
19, 1998). As stated in that final rule,
the alternative definition would be
applied to this regulation as well.
For purposes of assessing the impacts
of today's rule on small entities under
the CWA, we defined: (1) Small
businesses according to SBA size
standards; (2) small governmental
jurisdictions as governments of a city,
county, town, school district or special
district with a population of less than
50,000; and (3) small organizations as
any not-for-profit enterprise which is
independently owned and operated and
is not dominant in its field.
After considering the economic
impacts of today's final rule on small
entities, I certify that this action will not
have a significant economic impact on
a substantial number of small entities.
This final rule will not impose any
requirements on small entities. Today's
rule approves additional updated
versions of ASTM Methods, Standard
Methods, United States Geological
Survey (USGS) methods, and United
States Department of Energy (DOE)
methods for compliance with
wastewater monitoring and drinking
water standards and monitoring
requirements but does not require the
use of these specific versions. Previous
versions of these ASTM, Standard
Methods, USGS, and DOE methods are
not being withdrawn. State, territorial,
Tribal, and local governments and
public and privately owned public
, water systems arid laboratories
performing analyses on behalf of these
systems may continue to asa the
previous versions after the promulgation
of today's rule. The final rule merely
provides additional options. Any of the
testing procedures currently listed at 40
CFR parts 136,141, or 143 can be used
if monitoring is otherwise required for
this pollutant under the CWA or SDWA.
This rule also makes minor technical
corrections and clarifications to the
regulations.
C. Unfunded Mandates Reform Act
Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA), Public
Law 104-4, establishes requirements for
Federal agencies to assess the effects of
their regulatory actions on State, local,
and Tribal governments and the private
sector. Under section 202 of the UMRA,
EPA generally must prepare a written
statement, including a cost-benefit
analysis, for proposed and final rules
with "Federal mandates" that may
result in expenditures to State, local,
and Tribal governments, in the
aggregate, or to the private sector, of
$100 million or more in any one year.
Before promulgating an EPA rule for
' which a written statement is needed,
section 205 of the UMRA generally
requires EPA to identify and consider a
reasonable number of regulatory
alternatives and adopt the least costly,
most cost-effective or least burdensome
alternative that achieves the objectives
of the rule. The provisions of section
205 do not apply when they are
inconsistent with applicable law.
Moreover, section 205 allows EPA to
adopt an alternative other than the least
costly, most cost-effective or least
burdensome alternative if the
Administrator publishes with the final
rule an explanation why that alternative
was not adopted.
Before EPA establishes any regulatory
requirements that may significantly or
uniquely affect small governments,
including Tribal governments, it must
-------
Federal Register/Vol. 67, No. 205;/Wednesday, October 23, 2002/Rules and Regulations ' 65225
have developed under section 203 of the
UMRA a small government agency plan.
The plan must provide for notifying
potentially affected small governments,
enabling officials of affected small
governments to have meaningful and
timely input in the development of EPA
regulatory proposals with significant
Federal intergovernmental mandates,
and informing, educating, and advising
small governments on compliance with
the regulatory requirements.
Today's rule contains no Federal
mandates (under the regulatory
provisions of Title II of the UMRA) for
State, local, or Tribal governments or
the private sector. This rule imposes no
enforceable duty on any State, local or
Tribal governments or the private sector.
EPA has determined that this rule
contains no regulatory requirements that
might significantly or uniquely affect
small governments. Thus, today's rule is
not subject to the requirements of
sections 202, 203, and 205 of the
UMRA.
This rule provides additional
analytical methods with which to
conduct analyses for contaminants in
wastewater and drinking water, and
thus provides operational flexibility to
laboratory analysts. Since the rule does
not withdraw earlier versions of
methods, EPA anticipates no increase in
expenditure or burden.
D. Paperwork Reduction Act
This action does not impose an
information collection burden under the
provisions of the Paperwork Reduction
Act, 44 U.S.C. 3501 et seq. This action
merely provides additional options on
the selection of testing procedures when
monitoring is otherwise required under
the CWA or SDWA. Any of the testing
procedures approved at 40 CFR parts
136, 141, or 143 can be used if such
monitoring is required for a pollutant or
contaminant. Burden means the total
time, effort, or financial resources
expended by persons to generate,
maintain, retain or disclose or provide
information to or for a Federal agency.
This includes the time needed to review
instructions; develop,-acquire, install,
and utilize technology and systems for
the purpose of collecting, validating,
and verifying information processing
and maintaining information, and
disclosing and providing information;
adjust the existing ways to comply with
any previously applicable instructions
and requirements; train personnel to be
able to respond to a collection of
information; search data sources;
complete and review the collection of
information; and transmit or otherwise
disclose the information.
An agency may not conduct or
sponsor; ;and, a person is not required to
respond to a "collection of'information
unless redisplays a currently valid OMB
control number/The OMB control.
numbers-for EPA's regulations are listed
in 40 CFR part 9 and 48 CFR Chapter
15.
E. National Technology Transfer and
Advancement Act
As not^d in the proposed rule,
Section l2(d) of the National
Technology Transfer and Advancement
Act of 1993, ("NTTAA"), Public Law
104-113,; section 12(d) (15 U.S.C. 272
note), directs EPA to use voluntary
consensus standards in its regulatory
activities unless to do so would be
inconsistent with applicable law or
otherwise impractical. Voluntary
consensus standards are technical
standards (e.g., material specifications,
test methods, sampling procedures, and
business practices) that are developed or
adopted by voluntary consensus
standard;bodies. The NTTAA directs
EPA to provide Congress, through the
Office of Management and Budget
(OMB), Explanations when the Agency
decides not to use available and
applicable voluntary consensus
standards. In this rulemaking EPA is
approving updated versions of
previously approved voluntary
consensus standards published by
ASTM and Standard Methods for many
wastewater and drinking water
contaminants.
F. Executive Order 13045: Protection of
Children From Environmental Health
Risks and Safety Risks
Executive Order 13045 (62 FR 19885,
April 23, 1997) applies to any rule that:
(1) Is determined to be "economically
significant" as defined under Executive
Order 12866, and (2) concerns an
environmental health or safety risk that
EPA has reason to believe may have a
disproportionate effect on children. If
the regulatory action meets both criteria,
the Agency must evaluate the
environmental health or safety effects of
the planned rule on children, and
explain why the planned regulation is
preferabfe to other potentially effective
and reasonably feasible alternatives
considered by the Agency. This rule is
not subject to Executive Order 13045
because it is neither "economically
significant" as defined under Executive
Order 12866, nor does it concern an
environmental health or safety risk that
EPA has reason to believe may have a
disproportionate effect on children.
G. Executive Order 13132: Federalism
Executive Order 13132, entitled
"Federalism" (64 FR 43255, August 10,
1999), requires EPA to develop an
accountable process to ensure
"meaningful and timely input by State
and local officials in the development of
regulatory policies that have federalism
implications." "Policies that have
federalism implications" is defined in
the Executive Order to include
regulations that have "substantial direcl
effects on the States, on the relationship
between the national government and
the States, or on the distribution of
power and responsibilities among the
various levels of government."
' This final rule does not have
federalism implications. It will not have
substantial direct effects on the States,
on the relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132. Today's rule
provides governmental and other public
and private entities conducting analysis
in wastewater and drinking water the
option to use additional, updated
analytical methods to monitor
pollutants under the CWA or SDWA.
Such regulated entities may choose any
of these additional methods or continue
to use the methods listed under 40 CFR
parts 136, 141, and 143. Thus, Executive
Order 13132 does not apply to this rule.
H. Executive Order 13175: Consultation
and Coordination With Indian Tribal
Governments
Executive Order 13175, entitled
"Consultation and Coordination with
Indian Tribal Governments" (65 FR
67249, November 9, 2000), requires EPA
to develop an accountable process to
ensure "meaningful and timely input by
• Tribal officials in the development "t

Executive Order to include re-_;ui it:. :.^

-------
65226 Federal Register/Vol. 67, No. 205/Wednesday, October 23, 2002/Rules and Regulations
Today's rule provides Tribes conducting
analysis in wastewater and drinking
water the option to use additional
updated analytical methods to monitor
pollutants under the CWA or SDWA.
Tribes may choose any of these
additional methods or continue to use
the methods listed under 40 CFR parts
136,141, and 143. Thus, Executive
Order 13175 does not apply to this rule.
/. Congressional Review Act
The Congressional Review Act, 5
U.S.C. 801 et seq., as added by the Small
Business Regulatory Enforcement
Fairness Act of 1996 (SBREFA),"
generally provides that before a rule
may take effect, the agency
promulgating the rule must submit a
rule report, which includes a copy of
the rule, to each House of the Congress
and to tho Comptroller General of the
United States. EPA will submit a report
containing this rule and other required
information to the U.S. Senate, the U.S.
House of Representatives, and the
Comptroller General of the United
States prior to publication of the rule in
the Federal Register. A major rule
cannot take effect until 60 days after it
is published in the Federal Register.
This action is not a "major rule" as
defined by 5 U.S.C. 804(2). This rule
will be effective on November 22, 2002.
/. Executive Order 13211: Energy Effects
This rule is not subject to Executive
Order 13211, "Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use" (66
FR 2835S, May 22, 2001) because it is
not a significant regulatory action under
Executive Order 12866.
K, Plain Language Directive
Executive Order 12866 requires each
agency to write its rules in plain
language. Readable regulations .help the
public find requirements quickly and
understand them easily. They increase
compliance, strengthen enforcement,
and decrease mistakes, frustration,
phone calls, appeals, and distrust of
government. EPA made every effort to
write this preamble to the final rule in
as clear, concise, and unambiguous
manner as possible. Today's final rule is
mostly in a table format consistent with
the format of the CFR sections we are
amending.

Cincinnati (EMSL-CI), EPA-600/4-79-020, Revised March 1983 and 1979 where applicable.

niques of Water-Resource Investigations of the U.S. Geological Survey, Denver, CO, Revised 1989, unless otherwise stated.
3 "Official Methods of Analysis of the Association of Official Analytical Chemists," methods manual, 15th ed. (1990).
*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. Particu-
larly, if a colorimetric procedure is to be employed, it is necessary to ensure that all organo-metallio bonds be broken so that the metal is in a re-
active 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 mem-
brane filter. Following filtration of the sample, the referenced procedure for total metals must be followed. Sample digestion of the filtrate for dis-
solved 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.

distillation step is not necessary: however, manual distillation will be required to resolve any controversies.

12Carbonaceous biochemical oxygen demand (CBODS) 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 CBODs is required can the permittee report data using a nitrification inhibitor.

ants " of this Part 136 The full text of Method 1613B is incorporated by reference into this Part 136 and is available from the National Technical
Information Services as stock number PB95-104774. The standardized test procedure to be used to determine the method detection limit (MDL)
for these test procedures is given at Appendix B, "Definition and Procedure for the Determination of the Method Detection Limit," of this Part
136. '
3 "Methods for Benzidine: Chlorinated Organic Compounds, Pentachlorophenol and Pesticides in Water and Wastewater," U S. Environmental
Protection Agency, September, 1978. :
4 Method 624 may be extended to screen samples for Acrolein and Acrylonitrile. However, when they are known to be present, the preferred
method for these two compounds is Method 603 or Method 1624B.
5 Method 625 may be extended to include benzidine, hexachlorocyclopentadiene, N-nitrosodimethylamine, and N-nitrosodiphenylamine. How-
ever, when they are known to be present, Methods 605, 607, and 612, orMethod 1625B, are preferred methods for these compounds.
6 "Selected Analytical Methods Approved and Cited by trie United States Environmental Protection Agency," Supplement to the Fifteenth Edi-
tion of Standard Methods for the Examination of Water and; Wastewater (1981).
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 Meth-
ods. 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.
NOTE: These warning limits are promulgated as an "interjm final action with a request for comments."

7 Each analyst must make an initial, one-time, demonstration of their ability to generate acceptable precision and accuracy with Methods 608
and 625 (See Appendix A of this Part 136) in accordance with procedures given in Section 8.2 of each of these methods. Additionally, each lab-
oratory on an on-going basis, must spike and analyze 10% of all samples analyzed with Method 608 or 5% of all samples analyzed with Method
625 to monitor and evaluate laboratory data quality in accordance with Sections 8.3 and 8.4 of these methods. When the recovery of any param-
eter falls outside the warning limits, the analytical results for that parameter in the unspiked sample are suspect and cannot be reported to dem-
onstrate regulatory compliance. These quality control requirements also apply to the Standard Methods, ASTM Methods, and other Methods
cited.
Note: These warning limits are promulgated as an "Interim final action with a request for comments.'

Fifteenth Street, NW, Washington, DC 20005.
The cited methods published in any of these
three editions may be used.
(5) * * * The preparation of EC

(paragraph la) in Standard Methods for
the Examination of Water and
Wastewater, 18th edition (1992), 19th
edition (1995), and 20th edition (1998);
the cited method in any one of these
three editions may be used. * * *
(6)* * *
(i) EC medium supplemented with 50
ug/mL of 4-methylumbelliferyl-beta-D-
glucuronide (MUG) (final
concentration), as described in Method
9222G in Standard Methods for the
Examination of Water and Wastewater,
19th edition (1995) and 20th edition
(1998). Either edition may be used.
Alternatively, the 18th edition (1992)
may be used if at least 10 mL of EC
medium, as described in paragraph (f)(5)
of this section, is supplemented with 50
Ug/mL of MUG before autoclaving. The
inner inverted fermentation tube may be
omitted. If the 18th edition is used,
apply the procedure in paragraph (f)(5)
of this section for transferring a total
coliform-positive culture to EC medium
supplemented with MUG, incubate the
tube at 44.5 ± 0.2°C for 24 ± 2 hours, and
then observe fluorescence with an
ultraviolet light (366 nm) in the dark. If
fluorescence is visible, E. coli are
present.
(ii) Nutrient agar supplemented with
100 ug/mL of 4-methylumbelliferyl-
beta-D-glucuronide (MUG) (final
concentration), as described in Method
9222G in Standard Methods for the
Examination of Water and Wastewater,
•19th edition (1995) and 20th edition
(1998). Either edition may be used for
determining if a total coliform-positive
sample, as determined by a membrane
filter technique, contains E. coli.
Alternatively, the 13th edition (1092)
may be used if the membrane filter
containing a total coliform-positive
colony(ies) is transferred to nutrient
agar, as described in Method 9221B
(paragraph 3) of Standard Methods (iHth
edition), supplemented with 100 ug/niL
of MUG. If the 18th edition is used,
incubate the agar plate at 35°C for 4
hours and then observe the colony(ies)
under ultraviolet light (366 nm) in the
dark for fluorescence.-If fluorescence is
visible, E. coli are present.

12 Unfiltered, no digestion or hydrolysis.
13 Because MDLs reported in EPA Methods 200.7 and 200.9 were determined using a 2X precohcentration step during sample digestion,
MDLs determined when samples are analyzed by direct analysis (i.e., no sample digestion) will1 be higher. For direct analysis of cadmium and ar-
senic by Method 200.7, and arsenic by Method 3120 B sample preconcentration using pneumatic nebulization may be required to achieve lower
detection limits. Preconcentration may also be required for direct analysis of antimony, lead, and thallium by Method 200.9; antimony and lead by
Method 3113 B; and lead by Method D3559-90D unless multiple in-furnace depositions are made.

14 If ultrasonic nebulization is used in the determination of arsenic by Methods 200.7, 200.8, or SM 3120 B, the arsenic must be in the penta-
valent state to provide uniform signal response. For methods 200.7 and 3120 B, both samples and standards must be diluted in the same mixed
acid matrix concentration of nitric and hydrochloric acid with the addition of 100 nL of 30% hydrogen peroxide per 100ml of solution. For direct
analysis of arsenic with method 200.8 using ultrasonic nebulization, samples and standards must contain one mg/L of sodium hypochlorite.
'SAfter January 23, 2006 analytical methods using the ICP-AES technology, may not be used because the detection limits for these methods
are 0.008 mg/L or higher. This restriction means that the two ICP-AES methods (EPA Method 200.7 and SM 3120 B) approved for use for the
MCL of 0.05 mg/L may not be used for compliance determinations for the revised MCL of 0.01 mg/L. However, prior to 2005 systems may have
compliance samples analyzed with these less sensitive methods.
