AGENDA ITEM 

### 9 DATE: May 19, 2015 

### RECOMMENDATION: Conduct a public hearing to consider the adoption of the 2015 8-Hour Reasonably Available Control Technology — State Implementation Plan Analysis (RACT SIP Analysis): Continue hearing to June 16, 2015. 

### SUMMARY: The proposed adoption of the 2015 RACT SIP Analysis is necessary because the Antelope Valley Air Quality Management District (AVAQMD) has been designated as an ozone non-attainment area and classified Severe-15 for the 0.075 ppm 8- hour ozone standard. Therefore, the AVAQMD must submit a RACT SIP Analysis to the United States Environmental Protection Agency (USEPA) pursuant to the Federal Clean Air Act (FCAA). Continuation of the proposed action is necessary to address comments received from the USEPA. 

### BACKGROUND: The FCAA requires areas designated non-attainment and classified moderate and above to implement Reasonably Available Control Technology (RACT) for sources subject to Control Technique Guidelines (CTG) documents issued by the USEPA for "major sources" of volatile organic compounds (VOCs) and oxides of nitrogen (N0x) which are ozone precursors. Effective May 27, 2008 (73 FR 16436, March 27, 2008), USEPA lowered the primary ozone National Ambient Air Quality Standard (NAAQS) from 0.084 parts per million (ppm) to 0.075 ppm. For purposes of the FCAA, the District has been designated non-attainment for ozone and classified as Severe-15 for the 8-hour standard. As a result of this change, USEPA is requiring that all non-attainment areas adopt and submit an updated RACT SIP Analysis to ensure that District Rules adequately address current RACT requirements. In 2006 the AVAQMD adopted the 8-Hour Reasonably Available Control Technology — State Implementation Plan Analysis (RACT SIP Analysis) in response to change on March 9, 2006 of the previous ozone standard from measurement on a one- hour basis (1- hour ozone standard) to an eight-hour basis (8-hour ozone standard). On September 11, 2006, USEPA provided comments on the 2006 RACT SIP Analysis requesting additional analysis on several rules to determine if they still represented RACT. On March 13, 2014, the AVAQMD sent the 8-hour Ozone Reasonably Available Control Technology (RACT) State Implementation Plan (SIP) Analysis — Supplemental Analysis addressing

AGENDA ITEM

### 9 PAGE 2 these comments and providing the requested analysis of those rules identified by USEPA. This update was not acted on by the Governing Board pursuant to USEPA direction. The AVAQMD must now adopt an updated 2015 RACT SIP Analysis for the 2008 0.075 ppm 8- hour ozone NAAQS. The information contained in the original 2006 RACT SIP Analysis, the information in the supplemental 2014 RACT SIP Analysis, together with this document, will comprise an analysis sufficient to satisfy the RACT SIP Analysis request for the 0.075 ppm 8- hour ozone NAAQS. The resultant 2015 RACT SIP Analysis will, upon adoption, be submitted to USEPA for approval. A Notice of Exemption, Categorical Exemption (Class 8; 14 Cal. Code Reg. §15308) will be prepared by the AVAQMD for the adoption of the 2015 8-Hour Reasonably Available Control Technology — State Implementation Plan Analysis (RACT SIP Analysis)pursuant to the requirements of CEQA. 

### REASON FOR RECOMMENDATION: Health & Safety Code §§40702 and 40703 require the Governing Board to hold a public hearing before adopting rules and regulations. Also, 42 U.S.C. §7410(1) (FCAA §110(1)) requires that all SIP revisions be adopted after public notice and hearing. 

### REVIEW BY OTHERS: This item was reviewed as to legal form by Karen Nowak, District Counsel and by Eldon Heaston, Executive Director on or before May 4, 2015. 

### FINANCIAL DATA: No increase in appropriation is anticipated.
