Description: 

The Environmental Protection Agency (EPA) is proposing to partially approve and partially disapprove the state implementation plan (SIP) revision submitted by the State of California pursuant to the requirements of the Clean Air Act (CAA or ``Act'') for the implementation, maintenance, and enforcement of the 2015 national ambient air quality standards (NAAQS or ``standards'') for ozone. As part of this action, we are proposing to reclassify certain regions of the State for emergency episode planning purposes with respect to ozone. We are also proposing to approve into the SIP an updated state provision addressing CAA conflict of interest requirements, and emergency episode planning rules for Amador County Air Pollution Control District (APCD), Calaveras County APCD, Mariposa County APCD, Northern Sierra Air Quality Management District (AQMD), and Tuolumne County APCD. Finally, we are proposing to approve an exemption from emergency episode planning requirements for ozone for Lake County AQMD. We are taking comments on this proposal and, after considering any comments submitted, plan to take final action.
