Public Notice: Proposed Approval of California Air Plan Revision; San Joaquin Valley Unified Air Pollution Control District; Reasonably Available Control Technology Demonstration

Publish Date: 05/17/2018


EPA is proposing to approve revisions to the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD or “District”) portion of the California State Implementation Plan (SIP), which applies to the San Joaquin Valley of California (“Valley”). These revisions concern the District's demonstration regarding Reasonably Available Control Technology (RACT) requirements for the 2008 8-hour ozone National Ambient Air Quality Standard (NAAQS). We are also proposing to approve a public draft version of SJVUAPCD's supplement to its 2014 RACT SIP demonstration, which contains relevant permit conditions for J.R. Simplot's Nitric Acid plant in Helm, California (CA) and negative declarations where the District concludes it has no sources subject to certain Control Techniques Guidelines (CTG) documents. We are proposing action on local SIP revisions under the Clean Air Act (CAA or “the Act”). We are taking comments on this proposal and plan to follow with a final action.


Any comments must arrive by June 18, 2018.
