[CA 102-0091a; FRL-6150-9]
Approval and Promulgation of Implementation Plans; California
State Implementation Plan Revision; Yolo-Solano Air Quality Management
District
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is taking direct final action to approve a revision to the
California State Implementation Plan (SIP). The revision concerns Yolo-
Solano Air Quality Management District's (YSAQMD) Rule 2.34. This rule
controls oxides of nitrogen (NOX) from stationary gas
turbines. This action will incorporate the rule into the Federally
approved SIP. The intended effect of approving this rule is to regulate
emissions of NOX in accordance with the requirements of the
Clean Air Act, as amended in 1990 (CAA or the Act). EPA is finalizing
the approval of this rule into the California SIP under provisions of
the CAA regarding EPA action on SIP submittals, SIPs for national
primary and secondary ambient air quality standards and plan
requirements for nonattainment areas.
DATES: This direct final rule is effective on November 2, 1998. without
further notice, unless EPA receives adverse comments by October 5,
1998. If EPA received such comments, then it will publish a timely
withdrawal in the Federal Register informing the public that this rule
will not take effect.
ADDRESSES: Written comments must be submitted to Andrew Steckel at the
Region IX office listed below. Copies of the rule and EPA's evaluation
report are available for public inspection at EPA's Region IX office
during normal business hours. Copies of the submitted rule are also

SUPPLEMENTARY INFORMATION:
I. Applicability
The rule being approved into the California SIP includes YSAQMD's,
Rule 2.34, Stationary Gas Turbines. This rule was submitted by the
California Air Resources Board (CARB) to EPA on September 28, 1994.
II. Background
On November 15, 1990, the Clean Air Act Amendments of 1990 (CAA or
the Act) were enacted. Pub. L. 101-549, 104 Stat. 2399, codified at 42
U.S.C. 7401-7671q. The air quality planning requirements for the
reduction of NOX emissions through reasonably available
control technology (RACT) are set out in section 182(f) of the CAA. On
November 25, 1992, EPA published a proposed rule entitled ``State
Implementation Plans; Nitrogen Oxides Supplement to the General
Preamble; Clean Air Act Amendments of 1990 Implementation of Title I;
Proposed Rule,'' (the NOX Supplement) which describes the
requirements of section 182(f). The November 25, 1992, proposed rule
should be referred to for further information on the NOX
requirements and is incorporated into this document by reference.
Section 182(f) of the Clean Air Act requires States to apply the
same requirements to major stationary sources of NOX
(``major'' as defined in section 302 and section 182(c), (d), and (e))
as are applied to major stationary sources of volatile organic
compounds (VOCs), in moderate or above ozone nonattainment areas. The
Sacramento Metro Area in which the YSAQMD is located, is classified as
serious;1 therefore this area was subject to the RACT
requirements of section 182(b)(2), cited below, and the November 15,
1992 deadline.
---------------------------------------------------------------------------
\1\ Sacramento Metro Area retained its designation of
nonattainment and was classified by operation of law pursuant to
sections 107(d) and 181(a) upon the date of enactment of the CAA.
See 56 FR 56694 (November 6, 1991).
---------------------------------------------------------------------------
Section 182(b)(2) requires submittal of RACT rules for major
stationary sources of VOC emissions (not covered by a pre-enactment
control techniques guidelines (CTG) document or a post-enactment CTG
document) by November 15, 1992. There were no NOX CTGs
issued before enactment and EPA has not issued a CTG document for any
NOX sources since enactment of the CAA. The RACT rules
covering NOX sources and submitted as SIP revisions, are
expected to require final installation of the actual NOX
controls as expeditiously as practicable, but no later than May 31,
1995.
On September 28, 1994, the State of California submitted to EPA
YSAQMD's Rule 2.34, Stationary Gas Turbines, which was adopted by
YSAQMD on July 13, 1994. This submitted rule was found to be complete
on October 21, 1994 pursuant to EPA's completeness criteria that are
set forth in 40 CFR Part 51 Appendix V 2 and is being
finalized for approval into the SIP. By today's document, EPA is taking
direct final action to approve this submittal. This final action will
incorporate this rule into the Federally approved SIP.
---------------------------------------------------------------------------
\2\ EPA adopted the completeness criteria on February 16, 1990
(55 FR 5830) and, pursuant to section 110(k)(1)(A) of the CAA,
revised the criteria on August 26, 1991 (56 FR 42216).
---------------------------------------------------------------------------
NOX emissions contribute to the production of ground
level ozone and
[[Page 46893]]
smog. YSAQMD's Rule 2.34 controls emissions of NOX from
stationary gas turbines. The rule was adopted as part of YSAQMD's
efforts to achieve the National Ambient Air Quality Standards (NAAQS)
for ozone and in response to the CAA requirements cited above. The
following is EPA's evaluation and final action for this rule.
III. EPA Evaluation and Action
In determining the approvability of a NOX rule, EPA must
evaluate the rule for consistency with the requirements of the CAA and
EPA regulations, as found in section 110, and part D of the CAA and 40
CFR part 51 (Requirements for Preparation, Adoption and Submittal of
Implementation Plans). The EPA interpretation of these requirements,
which forms the basis for this action, appears in various EPA policy
guidance documents.3 Among these provisions is the
requirement that a NOX rule must, at a minimum, provide for
the implementation of RACT for stationary sources of NOX
emissions.
---------------------------------------------------------------------------
\3\ Among other things, the pre-amendment guidance consists of
those portions of the proposed post-1987 ozone and carbon monoxide
policy that concern RACT, 52 FR 45044 (November 24, 1987); ``Issues
Relating to VOC Regulation Cutpoints, Deficiencies, and Deviations,
Clarification to Appendix D of November 24, 1987 Federal Register
Notice'' (Blue Book) (notice of availability was published in the
Federal Register on May 25, 1988).
---------------------------------------------------------------------------
For the purposes of assisting State and local agencies in
developing NOX RACT rules, EPA prepared the NOX
Supplement to the General Preamble, cited above (57 FR 55620). In the
NOX Supplement, EPA provides guidance on how RACT will be
determined for stationary sources of NOX emissions. While
most of the guidance issued by EPA on what constitutes RACT for
stationary sources has been directed towards application for VOC
sources, much of the guidance is also applicable to RACT for stationary
sources of NOX (see section 4.5 of the NOX
Supplement). In addition, pursuant to section 183(c), EPA is issuing
alternative control technique documents (ACTs), that identify
alternative controls for categories of stationary sources of
NOX. The ACT documents will provide information on control
technology for stationary sources that emit or have the potential to
emit 25 tons per year or more of NOX. However, the ACTs will
not establish a presumptive norm for what is considered RACT for
stationary sources of NOX. In general, the guidance
documents cited above, as well as other relevant and applicable
guidance documents, have been set forth to ensure that submitted
NOX RACT rules meet Federal RACT requirements and are fully
enforceable and strengthen or maintain the SIP.
There is currently no version of YSAQMD's Rule 2.34, Stationary Gas
Turbines in the SIP. Rule 2.34 applies to all stationary gas turbines
with a power rating equal to or greater than 0.3 megawatt (MW).
The CARB, after reviewing statewide control measures and several
district rules, developed a RACT and BARCT guidance document entitled,
``Determination of Reasonably Available Control Technology and Best
Available Retrofit Control Technology for the Control of Oxides of
Nitrogen from Stationary Gas Turbines'' (RACT/BARCT determination).
CARB's RACT/BARCT determination specified RACT limits of 42 ppmv
(gas-fired) and 65 ppmv (oil-fired) for units rated equal to 0.3 MW and
greater. These limits are also specified as BARCT limits for units
equal to 0.3 MW and less than 2.9 MW, and units that are greater than
or equal to 4 MW and operating less than 877 hours per year. For units
equal to 2.9 and less than 10 MW, the BARCT limits are 25 ppmv (gas-
fired) and 65 ppmv (oil-fired). For units greater than or equal to 10
MW with SCR, the BARCT limits are 9 ppmv (gas-fired) and 25 ppmv (oil-
fired); those without SCR are 15 ppmv (gas-fired) and 42 ppmv (oil-
fired). The BARCT limits are corrected to 15 percent oxygen on a dry
basis and to turbine efficiency except those 42 ppmv (gas-fired) and 65
ppmv (oil-fired) limits and oil-fired units equal to 0.3 and less than
10 MW. The emission limits in CARB's RACT/BARCT determination are
generally comparable to those specified in the NOX
Supplement for electric utility boilers.
Rule 2.34 incorporates CARB's BARCT limits for gas turbines which
are more stringent than RACT limits. The rule contains adequate
recordkeeping requirements, and the appropriate test methods for
compliance determination are referenced. The rule is consistent with
all the guidance's other requirements. The exemptions provided in the
rule are consistent with EPA guidelines. Therefore, Rule 2.34 meets the
federal RACT By meeting the above requirements.
In evaluating the rule, EPA must determine whether the requirement
for RACT implementation by May 31, 1995 is met. The rule was written
such that final compliance is not required until July 13, 1998. Under
certain circumstances, the determination of what constitutes RACT could
include consideration of advanced control technologies, i.e.,
California's requirement for BARCT. In this case the CAA's May 1995
date for RACT implementation may be satisfied in BARCT rules that
establish ``interim RACT'' by May 1995, and require emission
limitations based on advanced control technologies such as BARCT be met
after May 1995.
Rule 2.34 meets EPA's RACT guidance for emission limits and
milestone towards final compliance by requiring that BARCT be
implemented by July 13, 1998, and that interim measures including a
compliance plan, an application for authority to construct, and start
and completion of construction be met to ensure progress toward
compliance with the final emission limits of the rule. A more detailed
discussion of the sources controlled, the controls required, and the
justification for why these controls represent RACT can be found in the
Technical Support Document (TSD) for Rule 2.34, dated July 31, 1998.
EPA has evaluated the submitted rule and has determined that it is
consistent with the CAA, EPA regulations and EPA policy. Therefore,
YSAQMD's Rule 2.34, Stationary Gas Turbines is being approved under
section 110(k)(3) of the CAA as meeting the requirements of section
110(a), section 182(b)(2), section 182(f) and the NOx
Supplement to the General Preamble.
Nothing in this action should be construed as permitting or
allowing or establishing a precedent for any future request for
revision to any State implementation plan. Each request for revision to
the State implementation plan shall be considered separately in light
of specific technical, economic and environmental factors and in
relation to relevant statutory and regulatory requirements.
EPA is publishing this rule without prior proposal because the
Agency views this as a noncontroversial amendment 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 SIP revision should
adverse comments be filed. This rule will be effective November 2, 1998
without further notice unless the Agency receives adverse comments by
October 5, 1998.
If the EPA received such comments, then EPA will publish a timely
withdrawal of the direct final rule informing the public that the rule
will not take effect. All public comments received will then be
addressed in a subsequent final rule based on the proposed rule. The
EPA will not institute a second comment period on this rule. Any
parties interested in
[[Page 46894]]
commenting on this rule should do so at this time. If no such comments
are received, the public is advised that this rule will be effective on
November 2, 1998 and no further action will be taken on the proposed
rule.
IV. Administrative Requirements
A. Executive Orders 12866 and 13045
The Office of Management and Budget (OMB) has exempted this
regulatory action from E.O. 12866 review.
This final rule is not subject to E.O. 13045, entitled ``Protection
of Children from Environmental Health Risks and Safety Risks,'' because
it is not an ``economically significant'' action under E.O. 12866.
B. Regulatory Flexibility Act
Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., EPA
must prepare a regulatory flexibility analysis assessing the impact of
any proposed or final rule on small entities. 5 U.S.C. 603 and 604.
Alternatively, EPA may certify that the rule will not have a
significant impact on a substantial number of small entities. Small
entities include small businesses, small not-for-profit enterprises,
and government entities with jurisdiction over populations of less than
50,000.
SIP approvals under section 110 and subchapter I, part 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 SIP approval does not impose any new requirements, the
Administrator certifies that it does not have a significant impact on
any small entities affected. Moreover, due to the nature of the
Federal-State relationship under the CAA, preparation of a flexibility
analysis would constitute Federal inquiry into the economic
reasonableness of State action. The Clean Air Act forbids EPA to base
its actions concerning SIPs on such grounds. Union Electric Co. v. U.S.
EPA, 427 U.S. 246, 255-66 (1976); 42 U.S.C. 7410(a)(2).
C. 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
Federal requirements. Accordingly, no additional costs to State, local,
or tribal governments, or to the private sector, result from this
action.
D. Submission to Congress and the General Accounting Office
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).
E. 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 2, 1998. 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).)
