Air Plan Approval; California; San Joaquin Valley Unified Air Pollution Control District; Reasonably Available Control Technology Demonstration

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD or "District") portion of the California State Implementation Plan (SIP). These revisions concern the District's 2014 demonstration regarding Reasonably Available Control Technology (RACT) requirements for the 2008 8-hour ozone National Ambient Air Quality Standard (NAAQS). We are also taking final action to approve into the California SIP the following documents that help support the District's RACT demonstration: SJVUAPCD's supplement to its 2014 RACT SIP demonstration, which contains SJVUAPCD's negative declarations where the District concludes it has no sources subject to certain Control Techniques Guidelines (CTG) documents and relevant permit conditions to implement RACT level requirements for J.R. Simplot's Nitric Acid plant in Helm, California (CA); and SJVUAPCD's 2016 Ozone Plan for the 2008 8-Hour Ozone Standard--Chapter 3.4 and Appendix C only. We are approving local SIP revisions to demonstrate that RACT is implemented as required under the Clean Air Act (CAA or the "the Act").
