40 CFR Part 141
[FRL-6216-9]
Suspension of Unregulated Contaminant Monitoring Requirements for
Small Public Water Systems
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is taking direct final action on the Unregulated
Contaminant Monitoring Regulation (UCMR) for public water systems. The
UCMR requires all public water systems to monitor for unregulated
contaminants during one year every five years. This direct final rule
concerns the suspension of monitoring by small and medium systems for
monitoring scheduled to begin after December 31, 1998. EPA is
suspending this monitoring since the revised UCMR program, required by
the 1996 Safe Drinking Water Act Amendments, is projected to begin
during this third round of monitoring. This will allow systems serving
10,000 or fewer persons to save the cost of monitoring under the
existing regulation, which if performed as scheduled would overlap with
monitoring under the revised UCMR program.
DATES: The regulation is effective on March 9, 1999 without further
notice unless EPA receives adverse comment by February 8, 1999. If EPA
receives such comment, it will publish a timely withdrawal in the
Federal Register informing the public that this rule will not take
effect. For judicial review purposes, this final rule is promulgated as
of 1:00 p.m. EST on January 22, 1999 as provided in 40 CFR 23.7.
ADDRESSES: Send written comments to the Comment Clerk, docket number W-
98-29, Water Docket (MC 4101), U.S. Environmental Protection Agency,

V. Public Involvement in Regulation Development
Potentially Regulated Entities: The regulated entities are public
water systems. All large community and nontransient non-community water
systems serving more than 10,000 persons would be required to monitor.
A community water system means a public water system which serves at
least 15 public service connections used by year-round residents or
regularly serves at least 25 year-round residents. Nontransient non-
community water system means a public water system that is not a
community water system and that regularly serves at least 25 of the
same persons over 6 months per year. Only a national representative
sample of community and non-transient non-community systems serving
10,000 or fewer persons would be required to monitor. Transient non-
community systems (i.e., systems that do not regularly serve at least
25 of the same persons over six months per year) would not be required
to monitor. States, Territories, and Tribes 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 and would be regulated by this action. Categories and
entities that may ultimately be regulated include the following:
----------------------------------------------------------------------------------------------------------------
Category Examples of potentially regulated entities SIC
----------------------------------------------------------------------------------------------------------------
State, Tribal and Territorial Governments.... States, Territories, and Tribes that analyze water 9511
samples on behalf of public water systems required to
conduct such analysis; States, Territories, and Tribes
that themselves operate community and nontransient non-
community water systems required to monitor.
Industry..................................... Private operators of community and nontransient non- 4941
community water systems required to monitor.
Municipalities............................... Municipal operators of community and nontransient non- 9511
community water systems required to monitor.
----------------------------------------------------------------------------------------------------------------
This table is not intended to be exhaustive, 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. If you have questions
regarding the applicability of this action to a particular entity,

Proposed Rule Canceling Monitoring for Systems Serving 10,000 or
Fewer Persons under Existing Regulation, 40 CFR 141.40
I. Background
The requirement to monitor unregulated contaminants was first
[[Page 1495]]
established by the 1986 Amendments to the Safe Drinking Water Act. The
current Unregulated Contaminant Monitoring (UCM) Program implemented
under 40 CFR 141.40 was established under three separate rulemakings
(See Federal Register documents at 52 FR 25720 (July 8, 1987), 56 FR
3526 (January 30, 1991), and 57 FR 31776 (July 17, 1992)). This program
includes 34 contaminants listed below in Table 1 which are to be
monitored by all community and non-transient non-community water
systems and 14 contaminants that are only required to be monitored at
the discretion of the State. Systems serving fewer than 150 service
connections were waived from monitoring provided that they sent a
letter to the State by January 1, 1991, or January 1, 1994, depending
upon the contaminant(s), making their facilities available to the
states for monitoring. Under 40 CFR 142.15, primacy states must report
the results of this monitoring to EPA. Repeat monitoring is required
every 5 years.

Under the requirement to monitor every five years, systems serving
more than 10,000 persons were to begin their third round of monitoring
for these unregulated contaminants no later than January 1, 1998.
Systems serving 3,300 to 10,000 persons were to begin their third
monitoring round no later than January 1, 1999, affecting 3,410 systems
nationwide. Systems serving less than 3,300 are required to begin their
third monitoring round no later than January 1, 2001, affecting
approximately 22,000 systems nationwide.
II. Today's Action
EPA is suspending the continuing requirement for small systems to
monitor every 5 years under the existing regulation. Under today's
action, systems serving 3,300 to 10,000 persons will not be required to
monitor after the rule is effective and systems serving less than 3,300
persons will not be required to monitor after January 1, 2001.
Effective January 1, 1999, EPA is suspending monitoring that would be
required to begin on or after that date. Any additional monitoring for
these systems will be a part of EPA's revision of the UCM regulations,
due by August 1999. This suspension does not eliminate the requirement
to monitor during monitoring rounds one and two, which were required to
begin in 1989 and 1994 respectively.
The reasons for this suspension of existing monitoring for systems
serving 10,000 or fewer persons are:
(a) The 1996 amendments to the SDWA require EPA to overhaul the UCM
program, with changes to the list of contaminants as well as the number
of systems that will need to monitor. The statutory deadline for the
revised UCM program is August 6, 1999.
(b) Beginning January 1, 1999, most systems serving 3,300 to 10,000
persons will need to initiate another round of monitoring for the
contaminants on the existing monitoring. Under the revised program,
this list of contaminants will change and many of these systems will
not need to monitor for the new list of contaminants.
(c) EPA already has received results from 28,000 systems from two
previous rounds of monitoring.
(d) EPA will have monitoring results from large systems (serving
more than 10,000 persons) for a third monitoring round which was to
begin no later than January 1, 1998. This will provide sufficient
confirming information on the occurrence of contaminants and any
additional action that EPA might need to take with regard to these
contaminants.
Therefore, because additional monitoring under the soon-to-be-
superceded program is unnecessary and burdensome for small systems, EPA
believes that the monitoring requirements for these systems should be
suspended.
This direct final rule grew out of the regulation development
process for the Unregulated Contaminant Monitoring Regulation. The UCMR
workgroup unanimously agrees that the cancellation of unregulated
contaminant monitoring requirements demonstrates good government. This
is because the proposed timing of the revised monitoring program occurs
close to the time of monitoring required by small systems under the
existing UCMR rule. The workgroup felt it was appropriate to suspend
monitoring because adequate data existed to assist EPA in future
regulatory decisions.
III. Cost Savings to Public Water Systems Affected by This Action
Since this action is deregulatory in nature, a cost savings will
accrue to these systems. EPA estimates that the cost for the affected
systems to monitor is $1,778,000 each year. Since these small systems
will not incur these costs, this rule results in cost savings to them.
IV. 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;
[[Page 1496]]
(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. 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 E.O. 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
preferable to other potentially effective and reasonably feasible
alternatives considered by the Agency.
This final rule is not subject to the Executive Order because it is
not economically significant as defined in E.O. 12866, and because the
Agency does not have reason to believe the environmental health or
safety risks addressed by this action present a disproportionate risk
to children. EPA believes that the Agency will have sufficient data
from the previous unregulated contaminant monitoring (three monitoring
rounds by systems serving more than 10,000 persons, and two monitoring
rounds by systems serving 10,000 or fewer persons) to enable it to
conduct the exposure assessments necessary for this sensitive
subpopulation.
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 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. The rule does not impose any
enforceable duties on these entities. Further, this rule withdraws
existing requirements, resulting in an estimated cost savings to these
governments and the private sector of $553,500 each year, since they
would no longer incur these costs. Thus, today's rule is not subject to
the requirements of sections 202 and 205 of the UMRA.
For the same reason, 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 section 203 of UMRA.
D. Paperwork Reduction Act
Under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq.,
information collection requirements must be submitted to the Office of
Management and Budget (OMB) for approval. An Information Collection
Request (ICR) document for existing requirements was previously
prepared by EPA (ICR No. 270.39) and approved by OMB (OMB No. 2040-
0090) and a copy may be obtained from Sandy Farmer by mail at OPPE
Regulatory Information Division; U.S. Environmental Protection Agency
(2137); 401 M St., S.W.; Washington, DC 20460, by email at:
[email protected], or by calling: (202) 260-2740. However,
this rule suspends the reporting requirements previously approved as
they relate to small systems. The Agency believes that by eliminating
this required monitoring in the years 1999 and 2000 and beyond,
reporting requirements will be commensurately reduced for state and
local entities affected. EPA estimates the reduction in burden hours to
be 3,774 hours, accruing in a total savings of $106,000.
E. Regulatory Flexibility Act
Under the Regulatory Flexibility Act (RFA), 5 U.S.C. 601 et seq.,
as amended by SBREFA, EPA generally is required to conduct a regulatory
flexibility analysis describing the impact of the regulatory action on
small entities as part of rulemaking. However, under section 605(b) of
the RFA, if EPA certifies that the rule will not have a significant
economic impact on a substantial number of small entities, EPA is not
required to prepare a regulatory flexibility analysis. Because this
rule removes existing requirements and does not add any new
requirements, pursuant to section 605(b) of the Regulatory Flexibility
Act, 5 U.S.C. 605(b), the Administrator certifies that this rule will
not have a significant economic impact on a substantial number of small
entities and will in fact have a positive impact on them by reducing
monitoring requirements in years 1999 and 2000 and beyond.
F. National Technology Transfer and Advancement Act
Under section 12(d) of the National Technology Transfer and
Advancement Act, the Agency is required to use voluntary consensus
standards in its regulatory activities unless doing so would be
inconsistent with applicable law or otherwise impractical. Voluntary
consensus standards are technical standards (e.g., material
specifications, test methods, sampling procedures, business practices,
etc.) that are developed or adopted by voluntary consensus standards
bodies. Where available and potentially applicable voluntary consensus
standards are not used by EPA, the Act requires the Agency to provide
Congress, through the Office of Management and Budget (OMB), an
explanation for the reasons for not using such standards.
Since this action establishes no technical standards, the
requirements of this Act do not apply to today's action.
[[Page 1497]]
G. Executive Order 12898--Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
Executive Order 12898--``Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations'' (February
11, 1994) focuses federal attention on the environmental and human
health conditions of minority populations and low-income populations
with the goal of achieving environmental protection for all
communities.
EPA believes that the Agency will have sufficient data from the
previous unregulated contaminant monitoring (three monitoring rounds by
systems serving more than 10,000 persons, and two monitoring rounds by
systems serving 10,000 or fewer persons) to enable it to conduct any
assessments necessary for these populations.
H. Executive Order 12875--Enhancing the Intergovernmental Partnership
Under Executive Order 12875, EPA may not issue a regulation that is
not required by statute and that creates a mandate upon a State, local
or tribal government, unless the Federal government provides the funds
necessary to pay the direct compliance costs incurred by those
governments, or EPA consults with those governments. If EPA complies by
consulting, Executive Order 12875 requires EPA to provide to the Office
of Management and Budget a description of the extent of EPA's prior
consultation with representatives of affected State, local and tribal
governments, the nature of their concerns, any written communications
from the governments, and a statement supporting the need to issue the
regulation. In addition, Executive Order 12875 requires EPA to develop
an effective process permitting elected officials and other
representatives of State, local and tribal governments ``to provide
meaningful and timely input in the development of regulatory proposals
containing significant unfunded mandates.''
Today's rule does not create a mandate on State, local or tribal
governments. The rule does not impose any enforceable duties on these
entities. Accordingly, the requirements of section 1(a) of Executive
Order 12875 do not apply to this rule.
I. Executive Order 13084--Consultation and Coordination With Indian
Tribal Governments
Under Executive Order 13084, EPA may not issue a regulation that is
not required by statute, that significantly or uniquely affects the
communities of Indian tribal governments, and that imposes substantial
direct compliance costs on those communities, unless the Federal
government provides the funds necessary to pay the direct compliance
costs incurred by the tribal governments, or EPA consults with those
governments. If EPA complies by consulting, Executive Order 13084
requires EPA to provide to the Office of Management and Budget, in a
separately identified section of the preamble to the rule, a
description of the extent of EPA's prior consultation with
representatives of affected tribal governments, a summary of the nature
of their concerns, and a statement supporting the need to issue the
regulation. In addition, Executive Order 13084 requires EPA to develop
an effective process permitting elected officials and other
representatives of Indian tribal governments ``to provide meaningful
and timely input in the development of regulatory policies on matters
that significantly or uniquely affect their communities.''
This rule does not impose any enforceable duties or any compliance
costs on Indian tribal governments. Thus, today's rule does not
significantly or uniquely affect the communities of Indian tribal
governments. Accordingly, the requirements of section 3(b) of Executive
order 13084 do not apply to this rule.
J. Administrative Procedure Act
EPA is publishing this rule without prior proposal because it views
this as a noncontroversial amendment and anticipate no adverse comment.
However, in the ``Proposed Rules'' section of today's Federal Register
publication, EPA is publishing a separate document that will serve as
the proposal for the suspension of monitoring for unregulated
contaminants by systems serving 10,000 or fewer persons if adverse
comments are filed. This rule will be effective on March 9, 1999
without further notice unless EPA receives adverse comment by February
8, 1999. If EPA receives adverse comment, it will publish a timely
withdrawal in the Federal Register informing the public that the rule
will not take effect. EPA will address all public comments in a
subsequent final rule based on the proposed rule. EPA will not
institute a second comment period on this action. Any parties
interested in commenting must do so at this time.
K. 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, 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 the 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 March 9, 1999 unless EPA
receives adverse comment and withdraws this rule before that date.
V. Public Involvement in Regulation Development
EPA's Office of Ground Water and Drinking Water has developed a
process for stakeholder involvement in its regulatory activities to
provide early input to regulation development. Activities related to
the Unregulated Contaminant Monitoring Program include specific
meetings focused on revising the unregulated contaminant monitoring
regulations to address the 1996 SDWA Amendments and the possibility of
eliminating future monitoring under the existing unregulated
contaminant monitoring regulation for systems serving 10,000 or fewer
persons.
OGWDW held its first stakeholder meeting to discuss options for the
development of the Unregulated Contaminant Monitoring Regulation on
December 2-3, 1997, in Washington, DC. A range of stakeholders attended
that meeting, including representatives of public water systems,
states, industry, health and laboratory organizations, and the public.
OGWDW staff prepared a background document for that meeting, Options
for Developing the Unregulated Contaminant Monitoring Regulation
(Working Draft), EPA 815-D-97-003, November 1997. A summary of that
meeting is also available. Prior to preparation of the UCMR regulation,
EPA also held a second stakeholders meeting on June 3-4, 1998, to
obtain input from interested on significant issues evolving from
drafting the regulation that needed further public input. OGWDW staff
prepared a public review document for that meeting, Background
Information and Draft Annotated Outline for a Proposed Unregulated
Contaminant Monitoring Regulation, Background Document,
[[Page 1498]]
(Working Draft), May 1998. A meeting summary is available.
Both meetings addressed the option of suspending unregulated
contaminant monitoring requirements for small public water systems.
Subsequent discussions with environmental organizations identified
their interest in having sufficient data to make regulatory decisions
for the current list of unregulated contaminants. Based on the data EPA
has from the first two monitoring rounds, EPA has made decisions
whether or not to regulate these contaminants. The contaminants from
this list selected for regulatory decisions are identified in the
Contaminant Candidate List, published March 2, 1998 in the Federal
Register (63 FR 10273). Additionally, the associations representing the
water supply industry expressed their support for this regulation. They
indicated that because the contaminants on the existing list are tested
using the same methods for regulated organic chemical testing, the
costs to test for additional contaminant should be minimal.
In general, the result of this public input is support for
eliminating existing unregulated contaminant monitoring requirements
for systems serving 10,000 or fewer persons so they will not have to
monitor for the existing list of unregulated contaminants in years 1999
and 2000 or beyond.
