Approval and Promulgation of Air Quality Implementation Plans; Commonwealth of Virginia; Section 110(a)(2) Infrastructure Requirements for the 1997 8-Hour Ozone and the 1997 and 2006 Fine Particulate Matter National Ambient Air Quality Standards
EPA is proposing to approve submittals from the Commonwealth of Virginia pursuant to the Clean Air Act (CAA) sections 110(k)(2) and (3). These submittals address the infrastructure elements specified in CAA section 110(a)(2), necessary to implement, maintain, and enforce the 1997 8-hour ozone and fine particulate matter (PM2.5) national ambient air quality standards (NAAQS) and the 2006 PM2.5 NAAQS. This proposed action is limited to the following infrastructure elements which were subject to EPA's completeness findings pursuant to CAA section 110(k)(1) for the 1997 8- hour ozone NAAQS dated March 27, 2008 and the 1997 PM2.5 NAAQS dated October 22, 2008: 110(a)(2)(A), (B), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M), or portions thereof; and the following infrastructure elements for the 2006 PM2.5 NAAQS: 110(a)(2)(A), (B), (C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M), or portions thereof.
Finding of Substantial Inadequacy of Implementation Plan; Call for Iowa State Implementation Plan Revision
Pursuant to the Environmental Protection Agency's (EPA) authority in the Clean Air Act (CAA or Act), section 110(k)(5), to call for plan revisions, EPA is making a finding that the Iowa State Implementation Plan (SIP) is substantially inadequate to maintain the 2006 24-hour National Ambient Air Quality Standard (NAAQS) for Fine Particulate Matter (PM2.5) in Muscatine County, Iowa. The specific SIP deficiencies needing revision are described below. EPA is also finalizing a timeline for Iowa to revise its SIP to correct these deficiencies by a date which is no later than 18 months after the effective date of this rule.
Approval and Promulgation of Implementation Plans; California; 2007 South Coast PM2.5
EPA is proposing to approve in part and disapprove in part state implementation plan (SIP) revisions submitted by California to provide for attainment of the 1997 fine particulate matter (PM2.5) national ambient air quality standards in the Los Angeles-South Coast area (South Coast). These SIP revisions are the South Coast 2007 Air Quality Management Plan (South Coast 2007 AQMP) (revised 2011) and South Coast-related provisions of the 2007 State Strategy (revised 2009 and 2011). EPA is proposing to approve the emissions inventories; air quality modeling; reasonably available control measures/reasonably available control technology demonstration; the reasonable further progress and attainment demonstrations; and the transportation conformity motor vehicle emissions budgets. EPA is also proposing to grant California's request to extend the attainment deadline for the South Coast to April 5, 2015 and to approve commitments to measures and reductions by the South Coast Air Quality Management District and the California Air Resources Board. Finally, we are proposing to disapprove the SIP's contingency measures and to reject the assignment of 10 tpd of NOX reductions to the federal government. This proposed rule amends EPA's November 22, 2010 proposed rule (75 FR 91294) on the South Coast PM2.5 plan and 2007 State strategy.
Notice of a Regional Waiver of Section 1605 (Buy American Requirement) of the American Recovery and Reinvestment Act of 2009 (ARRA) to the City of Ocean Shores (the City), WA
The Regional Administrator of EPA Region 10 is hereby granting a waiver from the Buy American requirements of ARRA Section 1605(a) under the authority of Section 1605(b)(2) [manufactured goods are not produced in the United States in sufficient and reasonably available quantities and of a satisfactory quality] to the City for the purchase of Greensand Plus pressure filter media, manufactured in Brazil. This is a project specific waiver and only applies to the use of the specified products for the ARRA project being proposed. Any other ARRA recipient that wishes to use the same product must apply for a separate waiver based on project specific circumstances. The waiver applicant states that the project requires the Greensand Plus filter media for use in their new shallow aquifer treatment plant. The design specifications of the project require a combination treatment process comprised of greensand filtration and MIEX [supreg] treatment. The greensand filtration process will primarily target the removal of iron and manganese, whereas the proprietary MIEX [supreg] process targets removal of dissolved organic carbon and other anionic species. Greensand Plus is currently used in the City's existing water treatment plant 1. In 2005, the City utilized Greensand Plus for their greensand filter media during pilot testing, and identified that product as the desired filter media for the proposed water treatment plant. The Regional Administrator is making this determination based on the review and recommendations of the Drinking Water Unit. The City has provided sufficient documentation to support their request.
