[EPA-R09-OAR-2007-1104; FRL-8512-7]

 
Revisions to the California State Implementation Plan, San 
Joaquin Valley Air Pollution Control District and Sacramento 
Metropolitan Air Quality Management District

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: EPA is taking direct final action to approve revisions to the 
San Joaquin Valley Air Pollution Control District (SJVAPCD) and 
Sacramento Metropolitan Air Quality Management District (SMAQMD) 
portions of the California State Implementation Plan (SIP). These 
revisions concern oxides of nitrogen (NOX) emissions from 
internal combustion engines and stationary gas turbines. We are 
approving local rules that regulate these emission sources under the 
Clean Air Act as amended in 1990 (CAA or the Act).

DATES: This rule is effective on March 10, 2008 without further notice, 
unless EPA receives adverse comments by February 11, 2008. If we 
receive such comments, we will publish a timely withdrawal in the 
Federal Register to notify the public that this direct final rule will 
not take effect.

ADDRESSES: Submit comments, identified by docket number EPA-R09-OAR-
2007-1104, by one of the following methods:

I. The State's Submittal

A. What rules did the State submit?

    Table 1 lists the rules we are approving with the dates that they 
were adopted by the local air agencies and submitted by the California 
Air Resources Board.

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

    On July 23, 2007 and October 16, 2007, respectively, EPA determined 
that these rule submittals met the completeness criteria in 40 CFR part 
51, Appendix V, which must be met before formal EPA review.

B. Are there other versions of these rules?

    The SJVAPCD first adopted Rule 4702 on August 21, 2003. That 
version was submitted to EPA on October 9, 2003, and approved on May 
18, 2004 (69 FR 28061). The SJVAPCD adopted revisions to the SIP-
approved version on June 16, 2005 and April 20, 2006, and CARB 
submitted them to us on October 20, 2005 and October 5, 2006. The 
SMAQMD first adopted Rule 413 on May 6, 1995, and EPA approved the rule 
into the SIP on March 1, 1996 (61 FR

[[Page 1820]]

7992). The SMAQMD adopted revisions to Rule 413 on May 1, 1997 and CARB 
submitted them to us on May 18, 1998. We approved those revisions into 
the SIP on February 11, 1999 (64 FR 6803). While we can act on only the 
most recently submitted version of each rule, we have reviewed 
materials provided with previous submittals.

C. What is the purpose of the submitted rule revisions?

    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. SJVAPCD Rule 4702 limits emissions of 
NOX, carbon monoxide (CO), and volatile organic compounds 
(VOC) from internal combustion engines. Changes from the SIP-approved 
version include the following:
     Rule 4702 now applies to compression-ignited engines, 
transportable engines, and engines in agricultural operations. The 
compliance date for agricultural engines is January 1, 2009.
     The amended rule contains new exemptions for engines used 
to propel instruments of husbandry, engines used exclusively to power 
mobile agricultural equipment, engines used to power wind machines for 
crop protection, and certain de-rated engines.
     The amended rule establishes requirements for District 
certification of exhaust control systems. These changes are meant to 
reduce the overall number of source tests required for Rule 4702 
compliance, without affecting emission reductions.
     The amended rule allows the use of a portable 
NOX analyzer for agricultural spark-ignited engines, to show 
initial compliance with Rule 4702 emissions standards until a source 
test can be arranged.
     The amended rule allows representative testing for spark-
ignited engines, and specifies requirements for that testing.
    SMAQMD Rule 413 limits emissions of NOX from stationary 
gas turbines. Amended Rule 413 extends the startup exemption for 
turbines with a rated output greater than or equal to 160 MW, and which 
are part of a combined cycle process, to up to 4 hours following a 
shutdown of the associated steam turbine of 72 hours or more; and up to 
3 hours following a shutdown of the associated steam turbine of between 
8 and 72 hours. It also allows a 6-hour averaging period for compliance 
with NOX limits for gas turbines with a rated output greater 
than 100 MW, and which are part of a combined cycle process, during a 
transient increase in emissions. EPA's technical support documents 
(TSDs) have more information about these rules.

II. EPA's Evaluation and Action

A. How is EPA evaluating the rules?

    Generally, SIP rules must be enforceable (see section 110(a) of the 
Act) and must not relax existing requirements (see sections 110(l) and 
193). The SJVAPCD and the SMAQMD both regulate serious ozone 
nonattainment areas (see 40 CFR part 81.305), so Rule 4702 and Rule 413 
must implement Reasonably Available Control Technology (RACT) for 
control of NOX emissions (see CAA 182(b)(2), (c) and 
182(f)). Both areas also regulate PM-10 nonattainment areas (see 40 CFR 
81.305). The SJVAPCD is a serious PM-10 nonattainment area, so Rule 
4702 must implement Best Available Control Measures (BACM), including 
Best Available Control Technology (BACT), for control of NOX 
emissions (see CAA 189(b)(1)(B) and 189(e)). The SMAQMD is a moderate 
PM-10 nonattainment area, so Rule 413 must implement Reasonably 
Available Control Measures (RACM), including RACT, for control of 
NOX emissions (see CAA 189(a)(1)(C) and 189(e)).
    Guidance and policy documents that we use to help evaluate 
enforceability, BACM/BACT and RACM/RACT requirements consistently 
include the following:
    1. ``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), 57 FR 55620, 
November 25, 1992.
    2. ``Issues Relating to VOC Regulation Cutpoints, Deficiencies, and 
Deviations,'' EPA, May 25, 1988 (the Bluebook).
    3. ``Guidance Document for Correcting Common VOC & Other Rule 
Deficiencies,'' EPA Region 9, August 21, 2001 (the Little Bluebook).
    4. EPA Memorandum to Regional Administrators from Steven A. Herman, 
Assistant Administrator for Enforcement and Compliance Assurance, and 
Robert Perciasepe, Assistant Administrator for Air and Radiation:

Malfunctions, Startup, and Shutdown,'' September 20, 1999.

Title I of the Clean Air Act Amendments of 1990, 59 FR 41998 (August 
16, 1994).

B. Do the rules meet the evaluation criteria?

    We believe these rules are consistent with the CAA, EPA 
regulations, and relevant policy and guidance regarding enforceability, 
BACM/BACT, RACM/RACT, and SIP relaxations. The inclusion of 
agricultural, transportable, and compression-ignited engines in SJVAPCD 
Rule 4702 clearly strengthens the rule, and the added exemptions are 
supported by District staff analysis. The representative testing 
provisions in Rule 4702 are based on EPA's ``Clean Air Act National 
Testing Guidance,'' and contain appropriate requirements to assure the 
achievement of emissions limits. The use of portable NOX 
analyzers allowed in Rule 4702 is a reasonable manner of checking 
compliance before the required performance of a full source test. The 
Rule 4702 requirements for certification of exhaust control systems are 
adequate to ensure control of emissions while simplifying rule 
compliance and enforcement.
    In our prior action to approve Rule 4702 into the SIP, we concluded 
that Rule 4702 implemented BACM/BACT as required for serious PM-10 
nonattainment areas under CAA sections 189(b)(1)(B) and 189(e) for 
NOX emissions from non-agricultural stationary internal 
combustion engines. See 69 FR 7098, 7102 (February 12, 2004) (proposed 
rule); 69 FR 28061 (May 18, 2004) (final rule). Revised Rule 4702 
continues to implement BACM/BACT for these engines. In addition, these 
revisions satisfy SJVAPCD's commitment to apply BACT-level controls to 
agricultural engines, consistent with its Amended 2003 PM-10 Plan. (The 
``Amended 2003 PM-10 Plan'' is the San Joaquin Valley Plan to Attain 
Federal Standards for Particulate Matter 10 Microns and Smaller, as

[[Page 1821]]

revised and supplemented by the plan amendments SJVAPCD adopted and 
submitted to EPA in December 2003. See 69 FR 30006, May 26, 2004, for 
the final rule approving these plan amendments into the California 
SIP.)
    As to SMAQMD Rule 413, while the extension of allowable startup 
periods and the provision for short-term excursions appear to relax the 
rule, these changes apply to only a small subset of the permitted 
plants in the District that cannot feasibly meet the current SIP rule's 
requirements during these limited periods. All of these sources have 
installed BACT-level NOX emission controls in accordance 
with SMAQMD's New Source Review (NSR) requirements. New turbines 
covered by the revised exemptions (i.e., combined-cycle turbines with 
capacities exceeding 100 MW) will also be subject to BACT for control 
of NOX emissions. These revisions to Rule 413 only provide 
limited flexibility to address operational necessities at large 
turbines during narrowly defined periods, and do not alter the control 
technology requirements that apply to these sources.
    In our prior actions to approve Rule 413 into the SIP, we concluded 
that this rule implemented RACT for NOX control as required 
for serious ozone nonattainment areas under CAA sections 182(b)(2) and 
182(f). See 61 FR 7992 (March 1, 1996); 64 FR 6803 (February 11, 1999). 
Revised Rule 413 continues to implement RACT for control of 
NOX emissions, as a precursor to both ozone and PM-10, from 
stationary gas turbines.
    The TSDs have more information on our evaluation of these rules.

C. EPA Recommendations To Further Improve the Rules

    EPA has no recommendations to further improve these rules.

D. Public Comment and Final Action

    As authorized in section 110(k)(3) of the Act, EPA is fully 
approving the submitted rules because we believe they fulfill all 
relevant requirements. We do not think anyone will object to this 
approval, so we are finalizing it without proposing it in advance. 
However, in the Proposed Rules section of this Federal Register, we are 
simultaneously proposing approval of the same submitted rules. If we 
receive adverse comments by February 11, 2008, we will publish a timely 
withdrawal in the Federal Register to notify the public that the direct 
final approval will not take effect and we will address the comments in 
a subsequent final action based on the proposal. If we do not receive 
timely adverse comments, the direct final approval will be effective 
without further notice on March 10, 2008. This will incorporate these 
rules into the federally enforceable SIP.
    Please note that if EPA receives adverse comment on an amendment, 
paragraph, or section of this rule and if that provision may be severed 
from the remainder of the rule, EPA may adopt as final those provisions 
of the rule that are not the subject of an adverse comment.

III. Statutory and Executive Order Reviews

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
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 action 
merely approves state law as meeting Federal requirements and imposes 
no additional requirements beyond those imposed by state law. 
Accordingly, the Administrator certifies that this 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 approves 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 (Pub. L. 104-4).
    This 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 approves 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 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 approves a state rule 
implementing a Federal standard.
    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 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 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.).
    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).
    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 March 10, 2008. 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).)
