ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 52
[CA 264-0388; FRL-7455-1]
Revisions to the California State Implementation Plan, Ventura
County Air Pollution Control District
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to approve revisions to the Ventura County
Air Pollution Control District (VCAPCD) portion of the California State
Implementation Plan (SIP). These revisions concern oxides of nitrogen
(NOX) emissions from stationary gas turbines. We are
proposing to approve a local rule to regulate these emission sources
under the Clean Air Act as amended in 1990 (CAA or the Act). We are
taking comments on this proposal and plan to follow with a final
action.
DATES: Any comments must arrive by March 28, 2003.
ADDRESSES: Mail comments to Andy Steckel, Rulemaking Office Chief (AIR-
4), U.S. Environmental Protection Agency, Region IX, 75 Hawthorne
Street, San Francisco, CA 94105-3901.
You can inspect copies of the submitted SIP revisions and EPA's
technical support document (TSD) at our Region IX office during normal
business hours. You may also see copies of the submitted SIP revisions
at the following locations: California Air Resources Board, Stationary
Source Division, Rule Evaluation Section, 1001 ``I'' Street,

I. The State's Submittal
A. What Rule Did the State Submit?
Table 1 lists the rule addressed by this proposal with the date
that it was adopted by local air agency and submitted by the California
Air Resources Board (CARB).
Table 1.--Submitted Rules
----------------------------------------------------------------------------------------------------------------
Rule Rule Title Adopted Submitted
----------------------------------------------------------------------------------------------------------------
VCAPCD.................................. 74.23 Stationary Gas Turbines........ 01/08/02 03/15/02
----------------------------------------------------------------------------------------------------------------
On May 7, 2002, this rule submittal was found to meet the
completeness criteria in 40 CFR part 51, appendix V, which must be met
before formal EPA review.
B. Are There Other Versions of This Rule?
VCAPCD adopted an earlier version of this rule on October 10, 1995,
and CARB submitted it to us on March 26, 1996. We published approval of
this previous version of rule 74.23 into the SIP on January 22, 1997
(14 FR 3220). VCAPCD adopted revisions to the SIP-approved version on
June 12, 2001 and CARB submitted to us on October 30, 2001. While we
can only act on the most recently submitted version, we have reviewed
material associated with previous submittals.
C. What Is the Purpose of the Submitted Rule Revisions?
Rule 74.23 applies to all stationary gas turbines with a rating
equal to or greater than 0.3 megawatts (MW) output and operated on
gaseous and/or liquid fuel. Stationary gas turbines in Ventura County
are used as cogeneration units to generate electricity and supply heat
for industrial processes, or as electric generators, and/or as
primemovers of equipment used in the oil production industry. The
primary purpose of the rule revisions is to slightly modify two
emission limits.
The TSD has more information about this rule.

II. EPA's Evaluation and Action
A. How Is EPA Evaluating This Rule?
Generally, SIP rules must be enforceable (see section 110(a) of the
Act), must require Reasonably Available Control Technology (RACT) for
major sources in nonattainment areas (see section 182(a)(2)(A), 182(f)
and 189(a)), and must not relax existing requirements (see sections
110(l) and 193). The VCAPCD regulates an ozone nonattainment area (see
40 CFR part 81), so Rule 74.23 must fulfill RACT.
Guidance and policy documents that we used to help evaluate
enforceability and RACT requirements consistently include the
following:
1. Issue Relating to VOC Regulation, Cut points, Deficiencies, and
Deviations (the Blue Book), U.S. EPA, May 25, 1988.
2. ``Guidance Document for Correcting VOC Rule Deficiencies'', U.S.
EPA Region 9, August 21, 2001 (the little bluebook).
3. State Implementation Plans: Nitrogen Oxides Supplement to the
General Preamble for the Implementation of Title I of the Clean Air Act
Amendment of 1990 (the ``NOX Supplement to the General
Preamble''), U.S. EPA, 57 FR 55620, November 25, 1992.
4. Requirements for Preparation, Adoption, and Submittal of
Implementation Plans, U.S. EPA, 40 CFR part 51.
5. State Implementation Plans for National Primary and Secondary
Ambient Air Quality Standards, Section 110 of the Clean Air Act, and
Plan Requirements for Nonattainment Areas, Title I Part D of the Clean
Air Act.
6. Determination of Reasonably Available Control Technology and
Best Available Retrofit Control Technology for the Control of Oxides of
Nitrogen From Stationary Gas Turbines, State of California Air
Resources Board, May 18, 1992.
7. Alternative Control Techniques (ACT) Document, NOX
Emissions from Stationary Gas Turbines, U.S. EPA, January 1993, EPA-
453/R-93-007.
8. Cost Effective Nitrogen Oxides (NOX) Reasonably
Available Control Technology (RACT), U.S. EPA Office of Air Quality
Planning and Standards, March 16, 1994.
B. Does This Rule Meet the Evaluation Criteria?
The substantive revisions to the rule were relaxation of the
NOX emission limit in section B.5 from 20 ppmv to 24 ppmv
for LM-2500 turbines, and the strengthening of the limit in section B.6
from 9 ppmv to 6.8 ppmv for LM-5000 turbines. We believe these changes
result in a net decrease and that this rule is consistent with the
relevant policy and guidance regarding enforceability, RACT, and SIP
relaxations. The TSD has more information on our evaluation.
C. Public Comment and Final Action
Because EPA believes the submitted rule fulfill all relevant
requirements, we are proposing to fully approve it as described in
section 110(k)(3) of the Act. We will accept comments from the public
on this proposal for the next 30 days. Unless we receive convincing new
information during the comment period, we intend to publish a final
approval action that will incorporate this rule into the federally
enforceable SIP.
III. Background Information
Why Was This Rule Submitted?
NOX helps produce ground-level ozone, smog and
particulate matter, which harm human health and the environment.
Section 110(a) of the CAA requires states to submit regulations that
control NOX emissions. Table 2 lists some of the national
milestones leading to the submittal of this local agency NOX
rule.
Table 2.--Ozone Nonattainment Milestones
------------------------------------------------------------------------
Date Event
------------------------------------------------------------------------
March 3, 1978............................ EPA promulgated a list of
ozone nonattainment areas
under the Clean Air Act as
amended in 1977. 43 FR 8964;
40 CFR 81.305.
May 26, 1988............................. EPA notified Governors that
parts of their SIPs were
inadequate to attain and
maintain the ozone standard
and requested that they
correct the deficiencies
(EPA's SIP-Call). See
section 110(a)(2)(H) of the
pre-amended Act.
November 15, 1990........................ Clean Air Act Amendments of
1990 were enacted. Pub. L.
101-549, 104 Stat. 2399,
codified at 42 U.S.C. 7401-
7671q.
May 15, 1991............................. Section 182(a)(2)(A) requires
that ozone nonattainment
areas correct deficient RACT
rules by this date.
------------------------------------------------------------------------
IV. Statutory and Executive Order Reviews
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
proposed action is not a ``significant regulatory action'' and
therefore is not subject to review by the Office of Management and
Budget. For this reason, this action is also not subject to Executive
Order 13211, ``Actions Concerning Regulations That Significantly Affect
Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This
proposed action merely proposes to approve state law as meeting Federal
requirements and imposes no additional requirements beyond those
imposed by state law. Accordingly, the Administrator certifies that
this proposed rule will not have a significant economic impact on a
substantial number of small entities under the Regulatory Flexibility
Act (5 U.S.C. 601 et seq.). Because this rule proposes to approve pre-
existing requirements under state law and does not impose any
additional enforceable duty beyond that required by state law, it does
not contain any unfunded mandate or significantly or uniquely affect
small governments, as described in the Unfunded Mandates Reform Act of
1995 (Public Law 104-4).
This proposed rule also does not have tribal implications because
it will not have a substantial direct effect on one or more Indian
tribes, on the relationship between the Federal Government and Indian
tribes, or on the distribution of power and responsibilities between
the Federal Government and Indian tribes, as specified by Executive
Order 13175 (65 FR 67249, November 9, 2000). This action also does not
have Federalism implications because it does 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 (64 FR 43255, August 10, 1999). This action
merely proposes to approve a state rule implementing a Federal
standard, and does not alter the relationship or the distribution of
power and responsibilities established in the Clean Air Act. This
proposed rule also is not subject to Executive Order 13045 ``Protection
of Children from Environmental Health Risks and Safety Risks'' (62 FR
19885, April 23, 1997), because it is not economically significant.
In reviewing SIP submissions, EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act. In
this context, in the
[[Page 8871]]
absence of a prior existing requirement for the State to use voluntary
consensus standards (VCS), EPA has no authority to disapprove a SIP
submission for failure to use VCS. It would thus be inconsistent with
applicable law for EPA, when it reviews a SIP submission, to use VCS in
place of a SIP submission that otherwise satisfies the provisions of
the Clean Air Act. Thus, the requirements of section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) do not apply. This proposed rule does not impose an information
collection burden under the provisions of the Paperwork Reduction Act
of 1995 (44 U.S.C. 3501 et seq.).
