On September 9, 2010 (75 FR 54806), EPA published a proposed rule proposing to approve in part and disapprove in part State implementation plan (SIP) revisions submitted by the State of Arizona to meet the Clean Air Act (CAA) requirements applicable to the serious Maricopa County (Phoenix) nonattainment area (Maricopa area). These requirements apply to the Maricopa area following EPA’s June 6, 2007 finding that the area failed to meet its December 31, 2006 serious area deadline to attain the national ambient air quality standards (NAAQS) for particulate matter of ten microns or less (PM–10). Under CAA section 189(d), Arizona was required to submit a plan by December 31, 2007 providing for expeditious attainment of the PM–10 NAAQS and for an annual emission reduction in PM–10 or PM–10 precursors of not less than five percent per year until attainment (189(d) plan). In the Agency’s September 9, 2010 proposed rule, EPA proposed to disapprove provisions of the 189(d) plan for the Maricopa area because they do not meet applicable CAA requirements for emissions inventories as well as for attainment, five percent annual emission reductions, reasonable further progress and milestones, and contingency measures, and to disapprove the 2010 motor vehicle emission budget in the 189(d) plan as not meeting the requirements of CAA section 176(c) and 40 CFR 93.118(e)(4). EPA also proposed a limited approval and limited disapproval of State regulations for the control of PM–10 from agricultural sources. Finally, EPA proposed to approve various provisions of State statutes relating to the control of PM–10 emissions in the Maricopa area. The September 9, 2010 proposed rule provided a 30-day public comment period ending on October 12, 2010. In response to a request for an extension of the comment period from Benjamin H. Grumbles, Director, Arizona Department of Environmental Quality, and Dennis Smith, Executive Director, Maricopa Association of Governments, submitted by letter dated October 4, 2010, EPA is jlentini on DSKJ8SOYB1PROD with PROPOSALS SUPPLEMENTARY INFORMATION: VerDate Mar<15>2010 16:04 Oct 13, 2010 Jkt 223001 extending the comment period to October 20, 2010.

ACTION: Proposed rule, extension of public comment period. AGENCY: The Environmental Protection Agency (EPA) Region 8 issued a Notice of Intent to Delete portions of the Denver Radium Superfund Site from the National Priorities List (NPL) on September 9, 2010 (75 FR 54779). The portions proposed for deletion are each of the 11 operable units at the Denver Radium Site, located in the City and County of Denver, Colorado. Groundwater contamination associated with Operable Unit 8 will remain on the NPL.
