Proposed Approval of Redesignathion Request and Maintenance Plan for Sacramento County for PM10 Standard

On July 12, 2013, Acting Regional Administrator Alexis Strauss signed a notice of proposed rulemaking to approve California’s request to redesignate the Sacramento County nonattainment area to attainment for the PM10 National Ambient Air Quality Standard and their plan for continuing to attain the PM10 standard for ten years beyond redesignation.

Determination of Attainment of the 1-Hour Ozone National Ambient Air Quality Standards in the Sacramento Metro Nonattainment Area in California

On October 3, 2012, EPA determed that the Sacramento Metro severe 1-hour ozone nonattainment area has attained the 1-hour ozone national ambient air quality standard based on 2007-2009 data.


Sacramento 1-Hour Ozone Clean Air Act Section 185 Termination

On May 9, 2011, EPA proposed to determine that California is no longer required to implement or submit a Clean Air Act (CAA) Section 185 fee program for 1-hour ozone as a revision to the State Implementation Plan (SIP) for the Sacramento Metro 1-hour ozone nonattainment area (Sacramento Metro Area). EPA has also taken an “interim final” action to stop sanctions from applying to the Sacramento Metro Area. Portions of the area were subject to sanctions because EPA previously determined that the State of California had not submitted a Section 185 SIP for those portions of the area. EPA is holding a 30-day public comment period starting on May 18, 2011, the date of publication of our proposal and interim final notices in the Federal Register.
