Environmental Protection Agency December 11, 2007 – Federal Register Recent Federal Regulation Documents

EPA is proposing to make a determination under the Clean Air Act (CAA) that the nonattainment area of Kewaunee County has attained the 8-hour ozone National Ambient Air Quality Standard (NAAQS). This determination is based on quality-assured ambient air quality monitoring data for the 2004-2006 ozone seasons that demonstrate that the 8-hour ozone NAAQS has been attained in the area. Preliminary monitoring data for 2007 continue to show monitored attainment of the NAAQS. EPA is proposing to approve a request from the State of Wisconsin to redesignate the Kewaunee County area to attainment of the 8-hour ozone NAAQS. The Wisconsin Department of Natural Resources (WDNR) submitted this request on June 12, 2007. In proposing to approve this request EPA is also proposing to approve, as a revision to the Wisconsin State Implementation Plan (SIP), the State's plan for maintaining the 8-hour ozone NAAQS through 2018 in the area. EPA also finds adequate and is proposing to approve the State's 2012 and 2018 Motor Vehicle Emission Budgets (MVEBs) for the Kewaunee County area.

The State of Rhode Island has applied to EPA for final authorization of certain changes to its hazardous waste program under the Resource Conservation and Recovery Act (RCRA). EPA has determined that these changes satisfy all requirements needed to qualify for final authorization, and is authorizing the State's changes through this immediate final action.

EPA is finding that the Imperial Valley serious PM-10 nonattainment area did not attain the 24-hour particulate matter (PM- 10) National Ambient Air Quality Standard (NAAQS) by the deadline mandated in the Clean Air Act (CAA), December 31, 2001. In response to this finding, the State of California must submit a revision to the California State Implementation Plan (SIP) that provides for attainment of the PM-10 standard in the Imperial Valley area and at least five percent annual reductions in PM-10 or PM-10 precursor emissions until attainment as required by CAA section 189(d). The State must submit the SIP revision by December 11, 2008.
