ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R09-OAR-2010-0596; FRL-9183-7]

 
Revisions to the California State Implementation Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve revisions to the San Joaquin 
Valley Unified Air Pollution Control District (SJVUAPCD) portion of the 
California State Implementation Plan (SIP). These revisions concern 
oxides of nitrogen (NOX) emissions from boilers, steam 
generators and process heaters with a rated heat input from 0.75 to 
less than 2.0 MMbtu/hr. We are approving a local rule that regulates 
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 September 1, 2010.

ADDRESSES: Submit comments, identified by docket number EPA-R09-OAR-
2010-0596, by one of the following methods:
    1. Federal eRulemaking Portal: www.regulations.gov. Follow the 
online instructions.
    2. E-mail: steckel.andrew@epa.gov.
    3. Mail or deliver: Andrew Steckel (Air-4), U.S. Environmental 
Protection Agency Region IX, 75 Hawthorne Street, San Francisco, CA 
94105-3901.
    Instructions: All comments will be included in the public docket 
without change and may be made available online at www.regulations.gov, 
including any personal information provided, unless the comment 
includes Confidential Business Information (CBI) or other information 
whose disclosure is restricted by statute. Information that you 
consider CBI or otherwise protected should be clearly identified as 
such and should not be submitted through www.regulations.gov or e-mail. 
www.regulations.gov is an ``anonymous access'' system, and EPA will not

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 the local air agency and submitted by the 
California Air Resources Board (CARB).

                                             Table 1--Submitted Rule
----------------------------------------------------------------------------------------------------------------
             Local agency                 Rule No.             Rule title             Adopted        Submitted
----------------------------------------------------------------------------------------------------------------
SJVUAPCD.............................            4308  Boilers, Steam Generators        12/17/09        05/17/10
                                                        and Process Heaters--
                                                        0.75 to less than 2.0
                                                        MMbtu/hr.
----------------------------------------------------------------------------------------------------------------

    On June 8, 2010, EPA determined that the submittal for SJVUAPCD 
Rule 4308 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 this rule?

    We approved an earlier version of Rule 4308 into the SIP on May 30, 
2007 (72 FR 29886).

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

    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. Rule 4308 limits NOX and 
CO emissions from boilers, steam generators, process heaters and water 
heaters with a total rated heat input equal or larger than 0.075 MMBtu/
hour and less than 2 MMBtu/hour. Rule 4308 was amended to include 
specific limits for instantaneous and pool water heaters as well as to 
strengthen the NOX emission limits for other units. EPA's 
technical support document (TSD) has more information about this rule.

II. EPA's Evaluation and Action

A. How is EPA evaluating the rule?

    Generally, SIP rules must be enforceable (see section 110(a) of the 
Act), must require Reasonably Available Control Technology (RACT) for 
each category of sources covered by a Control Techniques Guidelines 
(CTG) document as well as each major source in nonattainment areas (see 
sections 182(a)(2) and 182(f)), must implement Reasonably Available 
Control Measures (RACM) for PM2.5 nonattainment areas (see CAA section 
172(c)(1)), and must not relax existing requirements (see sections 
110(l) and 193). The SJVUAPCD regulates ozone and PM2.5 nonattainment 
areas (see 40 CFR part 81), so Rule 4308 must fulfill RACT and RACM.
    Guidance and policy documents that we use to evaluate 
enforceability, RACT and RACM 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. ``Determination of Reasonably Available Control Technology and 
Best Available Retrofit Control Technology for Industrial, 
Institutional, and Commercial Boilers, Steam Generators, and Process 
Heaters,'' CARB, July 18, 1991.
    5. ``Alternative Control Techniques Document-- NOX 
Emissions from Industrial/Commercial/Institutional (ICI) Boilers,'' 
U.S. EPA, 453/R-94-022, March 1994.
    6. ``Alternative Control Techniques Document--NOX 
Emissions.''

B. Does the rule meet the evaluation criteria?

    We believe this rule is consistent with the relevant policy and 
guidance regarding enforceability, RACT, RACM and SIP relaxations. The 
TSD has more information on our evaluation.

C. EPA Recommendations to Further Improve the Rule

    The TSD describes additional rule revisions that we recommend for 
the next time the local agency modifies the rule.

D. Public Comment and Final Action

    Because EPA believes the submitted rule fulfills 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. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a 
SIP submission that complies with the provisions of the Act and 
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, EPA's role is to approve State 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this action merely approves State law as meeting Federal 
requirements and does not impose additional requirements beyond those 
imposed by State law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     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);
     Does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement

[[Page 45082]]

Act of 1995 (15 U.S.C. 272 note) because application of those 
requirements would be inconsistent with the Clean Air Act; and
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).

    In addition, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the State, and EPA notes that it will not impose substantial direct 
costs on tribal governments or preempt tribal law.
