This submittal became complete by operation of law on July 31, 2007.

B. Are there other versions of this document?

There is no previous version of this document in the SIP.

C. What is the purpose of the submitted RACT SIP analysis?

VOCs and NOX help produce ground-level ozone and smog, which harm human health and the environment. Section 110(a) of the CAA requires States to submit regulations that control VOC and NOX emissions. Section 172(c)(1) and 182 require areas that are designated at moderate or above for ozone non-attainment to adopt RACT. The SCAQMD falls under this requirement as it is designated as a severe ozone non-attainment area under the 8-hour NAAQS for ozone (40 CFR 81.305). Therefore, the SCAQMD must, at a minimum, adopt RACT level controls for sources covered by a Control Technique Guidelines (CTG) document and for any major non-CTG source. Section IV.G. of EPA's final rule to implement the 8-hour ozone NAAQS (70 FR 71612, November 29, 2005) discusses RACT requirements. It states in part that where a RACT SIP is required, State SIPs implementing the 8-hour standard generally must assure that RACT is met, either through a certification that previously required RACT controls represent RACT for 8-hour implementation purposes or through a new RACT determination. The submitted document provides SCAQMD's analysis of why their rules meet RACT for the 8-hour NAAQS for ozone. EPA's technical support document (TSD) has more information about SCAQMD's RACT analysis.

II. EPA's Evaluation and Action

A. How is EPA evaluating the RACT SIP analysis?

Guidance and policy documents that we use to help evaluate whether the analysis fulfills RACT include the following:

1. Final Rule to Implement the 8-Hour Ozone National Ambient Air Quality Standard (70 FR 71612; November 29, 2005).

2. Letter from William T. Harnett to Regional Air Division Directors, (May 18, 2006), “RACT Qs & As—Reasonably Available Control Technology (RACT) Questions and Answers”.

3. 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).

4. RACT SIPs, Letter dated March 9, 2006 from EPA Region IX (Andrew Steckel) to CARB (Kurt Karperos) describing Region IX's understanding of what constitutes a minimally acceptable RACT SIP.

5. RACT SIPs, Letter dated April 4, 2006 from EPA Region IX (Andrew Steckel) to CARB (Kurt Karperos) listing EPA's current CTGs, ACTs, and other documents which may help to establish RACT.

6. Comment letter dated June 28, 2006 from EPA Region IX (Andrew Steckel) to SCAQMD (Joe Cassmassi) on the 8-hour Ozone Reasonably Available Control Technology—State Implementation Plan (RACT SIP) Analysis, draft staff report dated May 2006.

B. Does the analysis meet the evaluation criteria?

SCAQMD's staff report included a listing of all CTG source categories and cross matched those CTG categories against the corresponding District rule which implemented RACT. Given its designation as a severe ozone non-attainment area, SCAQMD was also required to analyze RACT for all sources that emit or have the potential to emit at least 25 tons per year (tpy) of VOC or NOX. SCAQMD staff searched their permitting database for all facilities that emitted at least 10 tpy of VOC or NOX and identified approximately 1,311 such facilities. The staff report states these facilities have a total of 17,607 permits. SCAQMD's staff report provides a listing of the Title V facilities along with an example of how each permitted source in a Title V facility is associated with a district rule and then those rules are compared to the applicable CTGs and ACTs. SCAQMD's RACT SIP analysis was made available for public comment prior to being adopted by the District. No public comments were received by the SCAQMD during the public workshop or during their 45-day comment period. We propose to find that the RACT SIP analysis performed by the SCAQMD is reasonable and demonstrates their rules meet RACT. We also propose to find that the analysis is consistent with the CAA, EPA regulations and the relevant policy and guidance documents listed above. The TSD has more information on our evaluation.

C. EPA Recommendation To Strengthen the SIP

The TSD describes recommendations for strengthening the SCAQMD SIP by amending and submitting Rules 1146.1 and 1110.2. SCAQMD's amendments to Rule 1146.1, “Emissions of NOX from Small Industrial, Institutional, and Commercial Boilers”, are planned for a Board hearing in the fall of 2008. We believe the emission limits in the existing SIP-approved Rule 1146.1 meets RACT and the anticipated amendments will further strengthen it. Rule 1110.2, “Emissions from Gaseous and Liquid Fueled Internal Combustion Engines”, was amended on February 1, 2008. In a separate action, Rule 1110.2 will be proposed for approval into the SIP.

D. Public Comment and Final Action

Because EPA believes the submitted analysis 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 document into the federally enforceable SIP.

III. Statutory and Executive Order Reviews

Under the Clean Air Act, the Administrator is required to approve a Start Printed Page 43188SIP 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.
