National Primary Drinking Water Regulations: Minor Correction to
Stage 2 Disinfectants and Disinfection Byproducts Rule and Changes in
References to Analytical Methods

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: In this action, EPA is proposing to make a minor correction to
the Stage 2 Disinfectants and Disinfection Byproducts Rule (DBPR) and
make minor, unrelated, changes in references to expedited, alternative
methods and other analytical methods in the regulations. EPA
promulgated the Stage 2 Disinfectants and Disinfectant Byproducts Rule
on January 4, 2006. A requirement for ground water systems serving 500-
9,999 people was unintentionally excluded from the final rule. As a
result, the rule allowed for less routine compliance monitoring than
intended for this category of Public Water Systems (PWSs). These PWSs
should have been required to monitor for both total trihalomethanes
(TTHM) and haloacetic acids (HAA5) concentrations at two locations. Due
to the error, they were only required to monitor for either TTHM or
HAA5 at two locations. EPA is also proposing to make minor, unrelated
changes in the CFR by adding references to the list of methods approved
under the Expedited Approval Process, removing references to outdated
methods, and specifying a new source for the publication titled
Technical Notes on Drinking Water Methods.

DATES: Comments must be received on or before January 13, 2009.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does This Action Apply to Me?

    Entities potentially regulated by this regulation are public water
systems (PWSs). A public water system, as defined by section 1401 of
the Safe Drinking Water Act (SDWA), is ``a system for the provision to
the public of water for human consumption through pipes or other
constructed conveyances, if such system has at least fifteen service
connections or regularly serves at least twenty-five individuals.'' EPA
defines ``regularly served'' as receiving water from the system 60 or
more days per year. Categories and entities potentially regulated by
this action include the following:

------------------------------------------------------------------------
                                   Examples of potentially regulated
           Category                             entities
------------------------------------------------------------------------
State, Tribal and Local        State, Tribal or local government-owned/
 Government.                    operated water supply systems using
                                ground water, surface water or mixed
                                ground water and surface water.
Federal Government...........  Federally owned/operated community water
                                supply systems using ground water,
                                surface water or mixed ground water and
                                surface water.
Industry.....................  Privately owned/operated community water
                                supply systems using ground water,
                                surface water or mixed ground water and
                                surface water.
------------------------------------------------------------------------

    This table is not intended to be an exhaustive list, but rather
provides a guide for readers regarding entities likely to be regulated
by this action. This table lists the types of entities that EPA is now
aware could potentially be regulated by this action. Other types of
entities not listed in the table could also be regulated. To determine
whether your facility is regulated by this action, you should carefully
examine the definition of ``public water system'' in Sec.  141.2, the
section entitled ``Coverage'' (Sec.  141.3), and the sections entitled
``General requirements'' (Sec. Sec.  141.600 and 141.620) in Title 40
of the Code of Federal Regulations and applicable criteria in
Sec. Sec.  141.605, and 141.621 of today's proposal. If you have
questions regarding the applicability of this action to a particular
entity, consult the person listed in the preceding FOR FURTHER
INFORMATION CONTACT section.

B. What Comments Will Be Considered?

    The public is invited to submit comments on the proposed changes to
the regulations discussed in this notice, namely, the minor correction
to the Stage 2 DBPR, the addition of cross references (to expedited
methods) to Appendix A to subpart C of part 141 in the CFR, and the
specific deletion of references to outdated methods in the CFR. EPA
does not solicit and will not respond in this rulemaking to any
comments on any other issues. In

particular, comments will not be responded to regarding the Stage 2
DBPR itself, the expedited method approval process, specific methods
approved in the expedited process, or the outdated methods or any
specific regulations regarding the outdated methods.

C. Proposed Minor Correction to the Stage 2 Disinfection and
Disinfectant Byproduct Rule (DBPR)

    Today's proposal corrects the monitoring frequency for one category
of public water systems (community water systems (CWSs) and
nontransient noncommunity (NTNCWSs) serving 500-9,999 people) to
correct an error introduced when the tables were modified prior to
publication of the final rule. EPA had modified the tables (in 40 CFR
141.605 and 141.621) in order to move all footnotes into the column
headers and out of the individual cells. In combining and rewriting the
footnote, EPA inadvertently modified the monitoring requirements for
ground water systems serving 500-9,999 people. As discussed in the
preamble to the final rule (page 429, USEPA 2006), ``EPA also believes
that more samples are necessary to characterize larger systems (as
defined by population) than for smaller systems.'' EPA intended for
those systems to monitor at a frequency that was twice the frequency
required for ground water systems serving fewer than 500 people, taking
two dual sample sets (each consisting of TTHM and HAA5 samples) rather
than single TTHM and HAA5 samples. However, the footnotes to the
monitoring tables in the preamble as well as the regulatory language
are incorrect as they do not reflect EPA's intended monitoring
requirement for these ground water systems (page 427, USEPA 2006). EPA
is proposing to correct the regulatory footnotes. The monitoring for
these small systems is not required to begin until the year 2012 or
2013 (page 415, USEPA 2006).
    In the Stage 2 DBPR Economic Analysis (USEPA, 2005a) and in the
Information Correction Rule Supporting Statement (Page 52, USEPA
2005b), EPA based the estimate of burden for these systems using the
intended monitoring frequency. Population-based monitoring is discussed
at length in the final Stage 2 DBPR (page 429, USEPA, 2006a) and the
additional costs for monitoring by ground water systems serving 500-
9,999 people are included (page 456, USEPA, 2006a). EPA is not
developing a new economic analysis for this proposal because the
existing economic analysis accounts for all costs associated with this
proposal.

D. Changes Related to Analytical Methods

1. Cross-References to Appendix A to Subpart C of Part 141
    When EPA determines that an alternative analytical method is
``equally effective'' (i.e., as effective as a method that has already
been promulgated in the regulations), the Safe Drinking Water Act
(SDWA) allows EPA to approve the use of the alternative method through
publication in the Federal Register. Section 1401(1) of SDWA states
that the newly approved methods ``shall be treated as an alternative
for public water systems to the quality control and testing procedures
listed in the regulation.'' EPA approved the first set of alternative
methods using this authority in a Federal Register action published on
June 3, 2008 (73 FR 31616) (USEPA 2008). As part of that action, EPA
added an appendix (Appendix A) to the regulations at 40 CFR Part 141,
which lists the newly approved methods.
    The current Part 141 drinking water regulations do not indicate
that additional approved methods are available and are listed in an
appendix. Therefore, EPA is proposing to amend the regulations at each
section that lists approved analytical methods to add cross references
to Appendix A to subpart C of part 141. This will make public water
systems, laboratories, and States more aware of the alternative
methods. References to the appendix are proposed to be added at the
following places:

--Section 141.21(f)(3) and (f)(6)
--Section 141.23(k)(1)
--Section 141.24(e)
--Section 141.25(a)
--Section 141.74(a)(1) and (a)(2)
--Section 141.131(b)(1), (c)(1), and (d)
--Section 141.402(c)(2)
--Section 141.704(a) and (b)
--Section 143.4(b)
2. Removal of Methods That Are No Longer Approved
    When the arsenic maximum contaminant level (MCL) was revised to
0.010 mg/L, some of the analytical methods that were previously
approved for analyzing samples for arsenic were no longer sensitive
enough to determine compliance. EPA added footnote 15 to the table at
40 CFR 141.23(k)(1) to indicate that use of these methods would not be
allowed after January 23, 2006. EPA is now proposing to update the
listing of approved arsenic methods to remove methods that are no
longer allowed (EPA 200.7, SM 3120 B and SM 3120 B-99). EPA is also
proposing to revise footnotes 13 and 14 to the table to paragraph
(k)(1) to remove references to methods that are no longer approved to
determine arsenic. EPA also proposes that Footnote 15 be removed and
the number reserved for future use.
    Paragraph (e)(2) of 40 CFR 141.24 lists methods that were approved
for use until June 1, 2001. Since these methods are no longer approved,
EPA proposes to remove the paragraph. EPA is also proposing to remove
footnote 1 to the table at 40 CFR 141.24(e)(1) because it refers to 40
CFR 141.24(e)(2). Footnote 1 would be reserved for future use. The
header to the table would be revised to remove the reference to
footnote 1.
3. Source for Obtaining Copies of Technical Notes on Drinking Water
Methods, EPA-600/R-94-173, October 1994
    This document is now available at no cost from the National Service
Center for Environmental Publications (NSCEP), P.O. Box 42419,
Cincinnati, OH 45242-0419 or http://www.epa.gov/nscep/. EPA is
proposing to update the following regulations to reflect this new
information:

--Section 141.23(k)(1)
--Section 141.74(a)(1)
--Section 143.4(b)

II. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

    This action is not a ``significant regulatory action'' under the
terms of Executive Order (EO) 12866 (58 FR 51735, October 4, 1993) and
is therefore not subject to review under the EO.

B. Paperwork Reduction

    This action does not impose any new information collection burden.
In this action, EPA is proposing to make a minor correction to the
Stage 2 DBPR, add references in the Code of Federal Regulations (CFR)
to the list of methods approved under the Expedited Approval Process,
remove references to outdated methods in the CFR and specify a new
source for the publication titled Technical Notes on Drinking Water
Methods. However, the Office of Management and Budget (OMB) has
previously approved the information collection requirements contained
in the Stage 2 DBPR existing regulations at 40 CFR 141 under the
provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and
has assigned OMB control number (number 2040-0265). The OMB control
numbers for EPA's

regulations in 40 CFR are listed in 40 CFR part 9. There is no burden
associated with regard to the minor, editorial changes in references to
analytical methods in the CFR. This action does not impose any new
information collection burden under the provisions of the Paperwork
Reduction Act, 44 U.S.C. 3501 et seq.

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act (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.
Small entities are defined as: (1) A small business as defined by the
Small Business Administration's (SBA) regulations at 13 CFR 121.201;
(2) a small governmental jurisdiction that is a government of a city,
county, town, school district or special district with a population of
less than 50,000; and (3) a small organization that is any ``not-for-
profit enterprise which is independently owned and operated and is not
dominant in its field.'' However, the RFA 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 establish an alternative small
business definition, agencies must consult with SBA's Chief Counsel for
Advocacy.
    For purposes of assessing the impacts of today's rule on small
entities, EPA considered small entities to be public water systems
(PWS) serving 10,000 or fewer persons. As required by the RFA, EPA
proposed using this alternative definition in the Federal Register (63
FR 7620, February 13, 1998), requested public comment, consulted with
the Small Business Administration (SBA), and finalized the alternative
definition 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.
    After considering the economic impacts of today's proposed rule on
small entities, I certify that this action will not have a significant
economic impact on a substantial number of small entities. This
proposed correction does not impose any new costs or burdens on PWSs.
The ground water system monitoring costs were accounted for and
detailed in the Stage 2 DBPR Economic Analysis and summarized in the
preamble of the Stage 2 DBPR (USEPA, 2006a). A copy of Stage 2 DBPR and
the final rule's Economic Analysis can be found in the Docket for this
proposed rule.
    We continue to be interested in the potential impacts of the
proposed rule on small entities and welcome comments on issues related
to such impacts.

D. Unfunded Mandates Reform Act

    This action contains no Federal mandates under the provisions of
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C.
1531-1538 for State, local, or tribal governments or the private
sector. This rule proposes a minor correction to the Stage 2 DBPR and
minor, editorial changes in references to analytical methods in the
Code of Federal Regulations. Therefore, this proposed rule is not
subject to the requirements of sections 202 or 205 of UMRA.
    This rule is also not subject to the requirements of section 203 of
UMRA because it contains no regulatory requirements that might
significantly or uniquely affect small governments. As previously
stated, this rule proposes a minor correction to the Stage 2
Disinfectants and Disinfection Byproducts Rule (DBPR) and minor,
editorial changes in references to analytical methods in the Code of
Federal Regulations; actions that will not significantly or uniquely
affect small governments.

E. 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 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.''
    This proposed 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. This rule proposes a minor
correction to the Stage 2 DBPR and minor, editorial changes in
references to analytical methods in the Code of Federal Regulations.
The Stage 2 DBPR (USEPA 2006) states that the final rule will not have
federalism implications and, with regard to the minor, editorial
changes to references of analytical methods in the Code of Federal
Regulations, those changes when finalized will not impose 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. Thus,
Executive Order 13132 does not apply to this rule.
    In the spirit of Executive Order 13132, and consistent with EPA
policy to promote communications between EPA and State and local
governments, EPA specifically solicits comment on this proposed rule
from State and local officials.

F. Executive Order 13175

    This action does not have tribal implications, as specified in
Executive Order 13175 (65 FR 67249, November 9, 2000). This rule
proposes a minor correction to the Stage 2 DBPR and minor, editorial
changes in references to analytical methods in the Code of Federal
Regulations, actions that will not have tribal implications. Thus,
Executive Order 13175 does not apply to this action.
    EPA specifically solicits additional comment on this proposed
action from tribal officials.

G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks

    EPA interprets EO 13045 (62 FR 19885, April 23, 1997) as applying
only to those regulatory actions that concern health or safety risks,
such that the analysis required under section 5-501 of the EO has the
potential to influence the regulation. This action is not subject to EO
13045 because it does not establish an environmental standard intended
to mitigate health or safety risks.

H. Executive Order 13211: Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use

    This action is not subject to Executive Order 13211 (66 FR 18355
(May 22, 2001)), because it is not a significant regulatory action
under Executive Order 12866.

I. National Technology Transfer and Advancement Act
    Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (``NTTAA''), Public Law 104-113, 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., materials specifications, test methods, sampling
procedures, and business practices) that are developed or adopted by
voluntary consensus standards bodies. The NTTAA directs EPA to provide
Congress, through OMB, explanations when the Agency decides not to use
available and applicable voluntary consensus standards.
    This proposed rulemaking does not propose technical standards.
Therefore, EPA is not considering the use of any voluntary consensus
standards.

J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations

    Executive Order (EO) 12898 (59 FR 7629 (Feb. 16, 1994)) establishes
federal executive policy on environmental justice. Its main provision
directs federal agencies, to the greatest extent practicable and
permitted by law, to make environmental justice part of their mission
by identifying and addressing, as appropriate, disproportionately high
and adverse human health or environmental effects of their programs,
policies, and activities on minority populations and low-income
populations in the United States.
    EPA has determined that this proposed rule will not have
disproportionately high and adverse human health or environmental
effects on minority or low-income populations because it does not
affect the level of protection provided to human health or the
environment. This rule proposes a minor correction to the Stage 2 DBPR
and minor, editorial changes in references to analytical methods in the
Code of Federal Regulations. These proposed actions will not have a
disproportionately high and adverse human health or environmental
effects on any population, including any minority or low-income
population.

\13\ Because MDLs reported in EPA Methods 200.7 and 200.9 were determined using a 2xpreconcentration step during sample digestion, MDLs determined when
  samples are analyzed by direct analysis (i.e., no sample digestion) will be higher. For direct analysis of cadmium by Method 200.7, 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 Method 200.8, the arsenic must be in the pentavalent state to provide uniform
  signal response. For direct analysis of arsenic with Method 200.8 using ultrasonic nebulization, samples and standards must contain 1 mg/L of sodium
  hypochlorite.
