SUPPLEMENTARY INFORMATION:
I. Background
Under section 111(d) of the Act, EPA has established procedures
whereby States submit plans to control certain existing sources of
``designated pollutants.'' Designated pollutants are defined as
pollutants for which a standard of performance for new sources applies
under section 111 but which are not ``criteria pollutants'' (i.e.,
pollutants for which National Ambient Air Quality Standards (NAAQS) are
set pursuant to sections 108 and 109 of the Act) or hazardous air
pollutants (HAPs) regulated under section 112 of the Act. As required
by section 111(d) of the Act, EPA established a process at 40 CFR part
60, subpart B, which States must follow in adopting and submitting a
section 111(d) plan. Whenever EPA promulgates new source performance
standards (NSPS) that control a designated pollutant, EPA establishes
EG in accordance with 40 CFR 60.22 which contain information pertinent
to the control of the designated pollutant from that NSPS source
category (i.e., the ``designated facility'' as defined at 40 CFR
60.21(b)). Thus, a State's section 111(d) plan for a designated
facility must comply with the EG for that source category as well as 40
CFR part 60, subpart B (40 CFR 60.23 through 60.26).
On March 12, 1996, EPA promulgated NSPS for new MSW landfills at 40
CFR part 60, subpart WWW (Standards of Performance for Municipal Solid
Waste Landfills) and EG for existing MSW landfills at 40 CFR part 60,
subpart Cc (Emission Guidelines and Compliance Times for Municipal
Solid Waste Landfills) (see 61 FR 9905). The pollutants regulated by
the NSPS and EG are MSW landfill emissions, which contain a mixture of
volatile organic compounds (VOC), other organic compounds, methane, and
HAPs. VOC emissions can contribute to ozone formation which can result
in adverse effects to human health and vegetation. The health effects
of HAPs include cancer, respiratory irritation, and damage to the
nervous system. Methane emissions contribute to global climate change
and can result in fires or explosions when they accumulate in
structures on or off the landfill site. To determine whether control is
required, nonmethane organic compounds (NMOC) are measured as a
surrogate for MSW landfill emissions. Thus, NMOC is considered the
designated pollutant. The designated facility which is subject
[[Page 50769]]
to the EG is each existing MSW landfill (as defined in 40 CFR 60.32c)
for which construction, reconstruction or modification was commenced
before May 30, 1991.
Pursuant to 40 CFR 60.23(a), States were required within nine
months after promulgation of subpart Cc (by December 12, 1996) to
submit either a plan to implement and enforce the EG or, if there are
no existing MSW landfills subject to the EG in the State, a negative
declaration letter.
EPA published a direct final rulemaking on June 16, 1998, in which
EPA amended 40 CFR part 60, subpart Cc (and subpart WWW), to add
clarifying language, make editorial amendments, and to correct
typographical errors (see 63 FR 32743). EPA published additional
technical amendments and corrections on February 24, 1999 (see 64 FR
9258). These amendments did not change the submittal date or the
requirements for State plans for existing MSW landfills.
On June 17, 1997, ADEQ submitted to EPA the Arizona State Plan for
implementing the MSW landfill EG. ADEQ submitted an amendment to the
Arizona State Plan on June 29, 1999. The following provides a brief
discussion of the requirements for an approvable State plan for
existing MSW landfills and EPA's review of the Arizona State Plan with
respect to those requirements. A detailed discussion of the State Plan
and EPA's evaluation can be found in the Technical Support Document for
the Arizona Plan (8/99).
II. Review of the Arizona MSW Landfill Plan
EPA has reviewed the Arizona section 111(d) plan for existing MSW
landfills against the requirements of 40 CFR part 60, subparts B and
Cc, as follows:
A. Identification of Enforceable State Mechanism for Implementing the
EG
Subpart B at 40 CFR 60.24(a) requires that the section 111(d) plan
include emissions standards, defined in 40 CFR 60.21(f) as ``a legally
enforceable regulation setting forth an allowable rate of emissions
into the atmosphere, or prescribing equipment specifications for
control of air pollution emissions.'' In the State of Arizona, ADEQ has
jurisdiction over stationary sources of air pollution in twelve of the
fifteen counties of Arizona. The enforceable mechanism in the areas
under ADEQ jurisdiction is a state air regulation: Arizona
Administrative Code (AAC) R18-2-731 ``Standards of Performance for
Existing Municipal Solid Waste Landfills'' (adopted April 4, 1997). In
each of the three counties--Maricopa, Pima, and Pinal--that are not
under ADEQ jurisdiction, the enforceable mechanism is a county air
regulation: Maricopa County Rule 321 ``Municipal Solid Waste
Landfills'' (adopted May 14, 1997); Pima County Code Section 17.16.390
``Standards of Performance for Existing Municipal Solid Waste
Landfills'' (adopted October 7, 1997); and Pinal County Article 5-34
``Standards of Performance for Existing Municipal Solid Waste
Landfills'' (adopted May 14, 1997). Thus, Arizona has met the
requirement of 40 CFR 60.24(a) to have legally enforceable emission
standards.
B. Demonstration of Legal Authority
Subpart B at 40 CFR 60.26 requires that the section 111(d) plan
demonstrate that the State has legal authority to adopt and implement
the emission standards and compliance schedules. The State has
demonstrated that ADEQ and the three county air agencies have
sufficient legal authority to adopt and enforce rules governing MSW
landfills in their respective jurisdictions. The State statutes
providing such authority are Article 2 (State Air Pollution Control)
and Article 3 (County Air Pollution Control) of Chapter 3 (Air Quality)
of Title 49 of the Arizona Revised Statutes (ARS).
C. Inventory of Existing MSW Landfills in the State Affected by the
State Plan
Subpart B at 40 CFR 60.25(a) requires that the section 111(d) plan
include a complete source inventory of all designated facilities
regulated by the EG: existing MSW landfills (i.e., those MSW landfills
that constructed, reconstructed, or modified prior to May 30, 1991)
that have accepted waste since November 8, 1987 or have additional
capacity for future waste deposition (see 40 CFR 60.32c(a)(1)). ADEQ
has submitted an inventory of all existing MSW landfills in Arizona as
part of the State Plan.
D. Inventory of Emissions from Existing MSW Landfills in the State
Subpart B at 40 CFR 60.25(a) requires that the 111(d) plan include
an emissions inventory that estimates emissions of the designated
pollutant regulated by the EG: NMOC. ADEQ has submitted an estimate of
annual NMOC emissions from the landfills in the source inventory as
part of the State Plan. ADEQ used the procedures in AP-42 ``Compilation
of Air Pollutant Emission Factors'' to estimate the NMOC emissions.
E. Emission Standards for MSW Landfills
Subpart B at 40 CFR 60.24(c) specifies that the State plan must
include emission standards that are no less stringent than the EG
(except as specified in 40 CFR 60.24(f) which allows for less stringent
emission standards on a case-by-case basis if certain conditions are
met). The State and county regulations in the Arizona Plan contain
emission standards that are no less stringent than the EG. Thus,
Arizona's section 111(d) plan complies with this requirement.
F. A Process for State Review and Approval of Site-Specific Gas
Collection and Control System Design Plans
Subpart Cc at 40 CFR 60.33c(b) requires State plans to include a
process for State review and approval of site-specific design plans for
required gas collection and control systems. The process for ADEQ and
county air district review and approval of site-specific gas collection
and control systems is specified in the State Plan. Thus, Arizona's
section 111(d) plan adequately addresses this requirement.
G. Compliance Schedules
The State's section 111(d) plan must include compliance schedules
that owners and operators of affected MSW landfills must meet in
complying with the requirements of the plan. Subpart Cc at 40 CFR
60.36c provides that planning, awarding of contracts, and installation
of air emission collection and control equipment capable of meeting the
EG must be accomplished within 30 months of the date on which the NMOC
emission rate equals or exceeds 50 megagrams per year. The State and
county regulations in the Arizona Plan contain the same compliance
schedule as subpart Cc.
H. Testing, Monitoring, Recordkeeping and Reporting Requirements
Subpart Cc at 40 CFR 60.34c specifies the testing and monitoring
provisions that State plans must include (60.34c specifically refers to
the requirements found in 40 CFR 60.754 to 60.756), and 40 CFR 60.35c
specifies the reporting and recordkeeping requirements (60.35c refers
to the requirements found in 40 CFR 60.757 and 60.758). The State and
county regulations in the Arizona Plan incorporate by reference the
requirements found in 40 CFR 60.754 to 60.758. Thus, the State Plan
satisfies the requirements of 40 CFR 60.34c and 60.35c.
[[Page 50770]]
I. A Record of Public Hearings on the State Plan
Subpart B at 40 CFR 60.23 contains the requirements for public
hearings that must be met by the State in adopting a section 111(d)
plan. The public hearing requirements were fulfilled during the State
and county rulemakings. ADEQ included documents in the Plan submittal
demonstrating that ADEQ and the county air districts complied with
these requirements, as well as the State's administrative procedures.
Therefore, EPA finds that Arizona has met this requirement.
J. Submittal of Annual State Progress Reports to EPA
Subpart B at 40 CFR 60.25(e) and (f) requires States to submit to
EPA annual reports on the progress of plan enforcement. Arizona
committed in its section 111(d) plan to submit annual progress reports
to EPA. The first progress report will be submitted by the State one
year after EPA approval of the State Plan. Therefore, EPA finds that
Arizona has adequately met this requirement.
In summary, EPA finds that the Arizona State Plan meets all of the
requirements applicable to such plans in 40 CFR part 60, subparts B and
Cc.
III. Final Action
Based on the rationale discussed above, EPA is approving the State
of Arizona section 111(d) plan for the control of landfill gas
emissions from existing MSW landfills.1 As provided by 40
CFR 60.28(c), any revisions to the Arizona State Plan or associated
regulations will not be considered part of the applicable plan until
submitted by the ADEQ in accordance with 40 CFR 60.28(a) or (b), as
applicable, and until approved by EPA in accordance with 40 CFR part
60, subpart B.
---------------------------------------------------------------------------
\1\ The State did not submit evidence of authority to regulate
existing MSW landfills in Indian Country; therefore, EPA is not
approving this Plan as it relates to those sources.
---------------------------------------------------------------------------
The EPA is publishing this rule without prior proposal because the
Agency views this as a noncontroversial action and anticipates no
adverse comments. However, in the proposed rules section of this
Federal Register publication, EPA is publishing a separate document
that will serve as the proposal to approve the 111(d) plan should
relevant adverse or critical comments be filed. This rule will be
effective November 19, 1999 without further notice unless the Agency
receives relevant adverse comments by October 20, 1999.
If EPA receives such comments, then EPA will publish a document
withdrawing the final rule and informing the public that the rule did
not take effect. All public comments received will be addressed 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 on this action should do so at this time. If
no such comments are received, the public is advised that this action
will be effective on November 19, 1999 and no further action will be
taken on the proposed rule.
Nothing in this action should be construed as permitting or
allowing or establishing a precedent for any future request for
revision to any section 111(d) plan. Each request for revision to the
section 111(d) plan shall be considered separately in light of specific
technical, economic, and environmental factors and in relation to
relevant statutory and regulatory requirements.
IV. Administrative Requirements
A. Executive Order 12866
The Office of Management and Budget (OMB) has exempted this
regulatory action from review under Executive Order 12866, entitled
``Regulatory Planning and Review.''
B. Executive Order 12875
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. 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, copies of 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.
C. Executive Order 13045
Protection of Children from Environmental Health Risks and Safety
Risks (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
preferable to other potentially effective and reasonably feasible
alternatives considered by the Agency.
This rule is not subject to Executive Order 13045 because it does
not involve decisions intended to mitigate environmental health or
safety risks.
D. Executive Order 13084
Under Executive Order 13084, EPA may not issue a regulation that is
not required by statute, that significantly affects 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. 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 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.''
Today's rule does not significantly or uniquely affect the
communities of Indian tribal governments. This action does not involve
or impose any requirements that affect Indian Tribes. Accordingly, the
requirements of section 3(b) of Executive Order 13084 do not apply to
this rule.
[[Page 50771]]
E. Regulatory Flexibility
The Regulatory Flexibility Act (RFA) generally requires an agency
to conduct a regulatory flexibility analysis of any rule subject to
notice and comment rulemaking requirements 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 not-for-profit enterprises, and small governmental
jurisdictions. This final rule will not have a significant impact on a
substantial number of small entities because State Plan approvals under
section 111(d) of the Clean Air Act do not create any new requirements
but simply approve requirements that the State is already imposing.
Therefore, because the Federal State Plan approval does not create any
new requirements, I certify that this action will not have a
significant economic impact on a substantial number of small entities.
Moreover, due to the nature of the Federal-State relationship under the
Clean Air Act, preparation of flexibility analysis would constitute
Federal inquiry into the economic reasonableness of state action. The
Clean Air Act forbids EPA to base its actions concerning State Plans on
such grounds. Union Electric Co. v. U.S. EPA, 427 U.S. 246, 255-66
(1976); 42 U.S.C. 7410(a)(2).
F. Unfunded Mandates
Under section 202 of the Unfunded Mandates Reform Act of 1995
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA
must prepare a budgetary impact statement to accompany any proposed or
final rule that includes a Federal mandate that may result in estimated
costs to State, local, or tribal governments in the aggregate; or to
private sector, of $100 million or more. Under section 205, EPA must
select the most cost-effective and least burdensome alternative that
achieves the objectives of the rule and is consistent with statutory
requirements. Section 203 requires EPA to establish a plan for
informing and advising any small governments that may be significantly
or uniquely impacted by the rule.
EPA has determined that the approval action promulgated does not
include a Federal mandate that may result in estimated costs of $100
million or more to either State, local, or tribal governments in the
aggregate, or to the private sector. This Federal action approves pre-
existing requirements under State or local law, and imposes no new
requirements. Accordingly, no additional costs to State, local, or
tribal governments, or to the private sector, result from this action.
G. Submission to Congress and the Comptroller General
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. This rule is not a
``major rule'' as defined by 5 U.S.C. 804(2).
H. Petitions for Judicial Review
Under section 307(b)(1) of the Clean Air Act, petitions for
judicial review of this action must be filed in the United States Court
of Appeals for the appropriate circuit by November 19, 1999. Filing a
petition for reconsideration by the Administrator of this final rule
does not affect the finality of this rule for the purposes of judicial
review nor does it extend the time within which a petition for judicial
review may be filed, and shall not postpone the effectiveness of such
rule or action. This action may not be challenged later in proceedings
to enforce its requirements. (See section 307(b)(2).)
