Environmental Protection Agency December 9, 2013 – Federal Register Recent Federal Regulation Documents

Notice is hereby given that the State of Oklahoma is revising its approved Public Water System Supervision Program. Oklahoma has adopted three EPA drinking water rules, namely the: (1) Long Term 2 Enhanced Surface Water Treatment Rule (LT2), (2) the Stage 2 Disinfectants and Disinfection Byproducts Rule (DBP2), and (3) the Ground Water Rule (GWR). EPA has determined that the proposed LT2, DBP2, and the GWR submitted by Oklahoma are no less stringent than the corresponding federal regulations. Therefore, EPA intends to approve this program revision.

EPA is proposing to approve the State of West Virginia's requests to redesignate to attainment the West Virginia portion of the Steubenville-Weirton, OH-WV nonattainment area (hereafter ``the Steubenville-Weirton Area'' or ``the Area'') for both the 1997 annual and the 2006 24-hour fine particulate matter (PM2.5) National Ambient Air Quality Standards (NAAQS or standards). EPA is also proposing to approve as a revision to the West Virginia State Implementation Plan (SIP), the associated maintenance plans to show maintenance of the 1997 annual and the 2006 24-hour PM2.5 NAAQS through 2025 for the West Virginia portion of the Area. West Virginia's maintenance plans include insignificance findings for the mobile source contribution of PM2.5 and nitrogen oxides (NOX) emissions to the West Virginia portion of the Area for both the 1997 annual and 2006 24-hour PM2.5 standards. EPA agrees with these insignificance findings, and is proposing approval of such findings for transportation conformity purposes. In addition, EPA is proposing to approve the 2008 emissions inventory for the West Virginia portion of the Area for the 2006 24-hour PM2.5 NAAQS. In this rulemaking action, EPA also addresses the effects of two decisions of the United States Court of Appeals for the District of Columbia (D.C. Circuit or Court): The Court's August 21, 2012 decision to vacate and remand to EPA the Cross-State Air Pollution Control Rule (CSAPR); and the Court's January 4, 2013 decision to remand to EPA two final rules implementing the 1997 annual PM2.5 standard. EPA has taken separate rulemaking action to approve the redesignation of the Ohio portion of the Steubenville-Weirton Area for the 1997 annual and 2006 24-hour PM2.5 NAAQS. These actions are being taken under the Clean Air Act. (CAA).
