Draft Integrated Science Assessment for Ozone and Related Photochemical Oxidants
EPA is announcing an extension of the public comment period for the first external review draft of a document titled, ``First External Review Draft Integrated Science Assessment for Ozone and Related Photochemical Oxidants'' (EPA/600/R-10/076A). The original Federal Register notice announcing the public comment period was published on February 28, 2011 (76 FR 10893). This assessment document was developed by the National Center for Environmental Assessment (NCEA) within EPA's Office of Research and Development as part of the review of the national ambient air quality standards (NAAQS) for ozone.

Approval and Promulgation of Gila River Indian Community's Tribal Implementation Plan
EPA is approving a Tribal implementation plan (TIP) submitted by the Gila River Indian Community (GRIC or Tribe) on February 21, 2007, as supplemented and amended on July 11, 2007, June 22, 2009, and July 17, 2010, and as described in our August 12, 2010 proposal. The TIP includes general and emergency authorities, ambient air quality standards, permitting requirements for minor sources of air pollution, enforcement authorities, procedures for administrative appeals and judicial review in Tribal court, requirements for area sources of fugitive dust and fugitive particulate matter, general prohibitory rules, and source category-specific emission limitations and standards. These provisions establish a base TIP that is suitable for the GRIC's reservation and regulatory capacities and that meets all applicable minimum requirements of the Clean Air Act (CAA or Act) and EPA regulations. The effect of this action is to make the approved portions of the GRIC TIP federally enforceable under the CAA and to further protect air quality within the exterior boundaries of the GRIC reservation.
Protocol Gas Verification Program and Minimum Competency Requirements for Air Emission Testing
EPA is finalizing rule revisions that modify existing requirements for sources affected by the federally administered emission trading programs including the NOX Budget Trading Program, the Acid Rain Program, and the Clean Air Interstate Rule. EPA is amending its Protocol Gas Verification Program (PGVP) and the minimum competency requirements for air emission testing (formerly air emission testing body requirements) to improve the accuracy of emissions data. EPA is also amending other sections of the Acid Rain Program continuous emission monitoring system regulations by adding and clarifying certain recordkeeping and reporting requirements, removing the provisions pertaining to mercury monitoring and reporting, removing certain requirements associated with a class-approved alternative monitoring system, disallowing the use of a particular quality assurance option in EPA Reference Method 7E, adding two incorporation by references that were inadvertently left out of the January 24, 2008 final rule, adding two new definitions, revising certain compliance dates, and clarifying the language and applicability of certain provisions.
