Environmental Protection Agency October 23, 2014 – Federal Register Recent Federal Regulation Documents

Partial Approval and Partial Disapproval of Air Quality State Implementation Plans; California; Infrastructure Requirements for Ozone, Fine Particulate Matter (PM2.5
Document Number: 2014-25278
Type: Proposed Rule
Date: 2014-10-23
Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is proposing to partially approve and partially disapprove several State Implementation Plan (SIP) revisions submitted by the State of California pursuant to the requirements of the Clean Air Act (CAA or the Act) for the implementation, maintenance, and enforcement of national ambient air quality standards (NAAQS) for ozone, fine particulate patter (PM2.5), lead (Pb), nitrogen dioxide (NO2), and sulfur dioxide (SO2). We refer to such SIP revisions as ``infrastructure'' SIPs because they are intended to address basic structural SIP requirements for new or revised NAAQS including, but not limited to, legal authority, regulatory structure, resources, permit programs, and monitoring necessary to assure attainment and maintenance of the standards. In addition, we are proposing to reclassify certain regions of the state for emergency episode planning purposes with respect to ozone, NO2, SO2, and particulate matter (PM). Finally, we are proposing to approve into the SIP several state provisions addressing CAA conflict of interest requirements into the California SIP and an emergency episode planning rule for Great Basin Unified Air Pollution Control District (APCD) for PM. We are taking comments on this proposal and, after considering any comments submitted, plan to take final action.

Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is proposing to approve a revision to the Imperial County portion of the California State Implementation Plan (SIP). This revision concerns Clean Air Act (CAA) requirements for volatile organic compounds and oxides of nitrogen emissions inventories in areas designated nonattainment for the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS). We are proposing to approve the 2002 volatile organic compound and oxides of nitrogen emissions inventories as submitted by Imperial County and California.
