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 (SJVAPCD) portion of the California State Implementation Plan (SIP). These revisions concern oxides of nitrogen (NO

X

) and particulate matter (PM) emissions from boilers of various capacities. We are approving local rules that 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 September 14, 2009.

ADDRESSES:

Submit comments, identified by docket number EPA-R09-OAR-2009-0474, by one of the following methods:

I. The State's Submittal

A. What rules did the State submit?

Table 1 lists the rules addressed by this proposal with the dates that they were adopted by the local air agency and submitted by the California Air Resources Board (CARB).

On April 20, 2009, these rule submittals were 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 these rules?

We approved a version of Rule 4306 into the SIP on May 18, 2004 and of Rule 4307 on May 30, 2007. There are no outstanding submittals of these Rules.

C. What is the purpose of the submitted revisions?

NO

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 NO

X

emissions. PM contributes to effects that are harmful to human health and the environment, including premature mortality, aggravation of respiratory and cardiovascular disease, decreased lung function, visibility impairment, and damage to vegetation and ecosystems. Section 110(a) of the CAA requires States to submit regulations that control PM emissions. Rule 4306 limits NO

X

and Carbon Monoxide (CO) emissions from boilers, steam generators and process heaters fired on gaseous or liquid fuel with a total rated heat input larger than 5 MMBtu/hour. This Rule was amended to address an EPA concern. Rule 4307 limits NO

, SO

, PM

and CO emissions from boilers, steam generators and process heaters fired on gaseous or liquid fuel with a total rated heat input between 2 and 5 MMBtu/hour. Rule 4307 was amended to include requirements to regulate SO

2

and PM

10

emissions as well as to strengthen the emission limits for NO

X

. EPA's technical support document (TSD) has 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), 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)), and must not relax existing requirements (see sections 110(l) and 193). The SJVAPCD regulates an ozone nonattainment area (see 40 CFR part 81), so Rules 4306 and 4307 must fulfill RACT. In addition, SIP rules must implement Reasonably Available Control Measures (RACM), including Reasonably Available Control Technology (RACT), in nonattainment areas (see CAA sections 172(c)(1)). The SJVAPCD regulates a PM-2.5 nonattainment area (see 40 CFR part 81), so Rules 4306 and 4307 must implement a RACM level of control.

Guidance and policy documents that we use to help 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 NO

X

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. “State Implementation Plans; General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990,” 57 FR 13498, April 16, 1992; 57 FR 18070, April 28, 1992.

5. “Clean Air Fine Particle Implementation Rule” 72 FR 20586, April 25, 2007.

6. “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.

7. “Alternative Control Techniques Document—NO

X

Emissions from Industrial/Commercial/Institutional (ICI) Boilers”, US EPA 453/R-94-022, March 1994.

8. “Alternative Control Techniques Document—NO

X

Emissions from Utility Boilers”, US EPA 452/R-93-008, March 1994.

B. Do the rules meet the evaluation criteria?

We believe these rules are consistent with the relevant policy and guidance regarding enforceability, RACT, RACM and SIP relaxations. The TSDs have more information on our evaluation.

C. EPA Recommendations to Further Improve the Rules

The TSDs describe additional rule revisions that do not affect EPA's current action but are recommended for the next time the local agency modifies the rules.

D. Public Comment and Final Action

Because EPA believes the submitted rules fulfill all relevant requirements, we are proposing to fully approve them 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 these rules 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 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.
