Determination of Attainment for the West Central Pinal Nonattainment Area for the 2006 Fine Particle Standard; Arizona; Determination Regarding Applicability of Clean Air Act Requirements
EPA is taking final action to determine that the West Central Pinal nonattainment area in Arizona has attained the 2006 24-hour fine particle (PM2.5) National Ambient Air Quality Standard (NAAQS). This determination is based upon complete, quality-assured, and certified ambient air monitoring data showing that this area has monitored attainment of the 2006 24-hour PM2.5 NAAQS based on the 2010-2012 monitoring period. Based on the above determination, the requirements for this area to submit an attainment demonstration, together with reasonably available control measures (RACM), a reasonable further progress (RFP) plan, and contingency measures for failure to meet RFP and attainment deadlines are suspended for so long as the area continues to attain the 2006 24-hour PM2.5 NAAQS.
Water Quality Standards Regulatory Clarifications
The Environmental Protection Agency (EPA) is proposing changes to the federal water quality standards (WQS) regulation which helps implement the Clean Water Act. The changes will improve the regulation's effectiveness in restoring and maintaining the chemical, physical, and biological integrity of the nation's waters. The EPA is seeking comments from interested parties on these proposed revisions. The core of the current regulation has been in place since 1983; since then, a number of issues have been raised by states, tribes, or stakeholders or identified by the EPA in the implementation process that will benefit from clarification and greater specificity. The proposed rule addresses the following key program areas: Administrator's determinations that new or revised WQS are necessary, designated uses, triennial reviews, antidegradation, variances to WQS, and compliance schedule authorizing provisions.
Approval and Promulgation of Air Quality Implementation Plans; State of New Jersey; Redesignation of Areas for Air Quality Planning Purposes and Approval of the Associated Maintenance Plan
On December 26, 2012 the New Jersey Department of Environmental Protection (NJDEP) submitted a request for the Environmental Protection Agency (EPA) to approve the redesignation of the New Jersey portion of the New York-N.New Jersey-Long Island, NY-NJ- CT nonattainment area, and the New Jersey portion of the Philadelphia- Wilmington, PA-NJ-DE nonattainment area, from nonattainment to attainment for the 1997 annual and the 2006 24-hour Fine Particle (PM2.5) National Ambient Air Quality Standards (NAAQS). In conjunction with its redesignation request, New Jersey submitted a State Implementation Plan (SIP) revision containing a maintenance plan for the areas that provides for continued maintenance of the 1997 annual and 2006 24-hour PM2.5 NAAQS. The submittals included the 2007 ammonia (NH3), volatile organic compounds (VOC), nitrogen oxides (NOX), direct PM2.5 and sulfur dioxide (SO2) emissions inventories submitted to meet the comprehensive emissions inventory requirements of section 172(c)(3) of the Clean Air Act (CAA), and accompanying motor vehicle emissions budgets. EPA is taking final action to approve the requested SIP revisions and to redesignate the New Jersey portions of the New York- N.New Jersey-Long Island, NY-NJ-CT nonattainment area, and the Philadelphia-Wilmington, PA-NJ-DE nonattainment area, to attainment for the 1997 annual and the 2006 24-hour PM2.5 NAAQS.
