Approval of Air Quality Implementation Plans; California; Ventura County Air Pollution Control District; Reasonably Available Control Technology for Ozone
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by California for the Ventura County Air Pollution Control District (VCAPCD) portion of the California SIP. The submitted SIP revision contains the District's demonstration regarding Reasonably Available Control Technology (RACT) requirements for the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS). We are proposing to approve the submitted SIP revision under Clean Air Act as amended in 1990 (CAA or the Act). We are taking comments on this proposal and plan to follow with a final action.

Approval and Promulgation of Air Quality Implementation Plans; State of Colorado; Second Ten-Year PM10
The Environmental Protection Agency (EPA) is taking final action partially approving and partially disapproving State Implementation Plan (SIP) revisions submitted by the State of Colorado. On March 31, 2010, the Governor of Colorado's designee submitted to EPA a revised maintenance plan for the Pagosa Springs area for the National Ambient Air Quality Standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to 10 microns (PM10). The State adopted the revised maintenance plan on November 19, 2009. As required by Clean Air Act (CAA) section 175A(b), this revised maintenance plan addresses maintenance of the PM10 standard for a second 10-year period beyond the area's original redesignation to attainment for the PM10 NAAQS. EPA is taking final action approving the revised maintenance plan with the exception of one aspect of the plan's contingency measures. EPA's approval includes the revised maintenance plan's 2021 transportation conformity motor vehicle emissions budget (MVEB) for PM10. In taking final action to approve the revised maintenance plan, we are taking final action to exclude from use in determining whether or not Pagosa Springs continues to attain the 24-hour PM10 NAAQS, exceedances of the 24-hour PM10 NAAQS that were recorded at the Pagosa Springs PM10 monitor on March 22, 2009, April 3, 2009, April 5, 2010, April 28, 2010, April 29, 2010, May 11, 2010, and May 22, 2010 because the exceedances meet the criteria for exceptional events caused by high wind natural events. This action is being taken under sections 110 and 175A of the CAA.
Approval and Promulgation of Air Quality Implementation Plans; New Hampshire; Decommissioning of Stage II Vapor Recovery Systems
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of New Hampshire Department of Environmental Services. This revision includes regulatory amendments that require the decommissioning of Stage II vapor recovery systems at gasoline dispensing facilities by December 22, 2015, and a demonstration that such removal is consistent with the Clean Air Act and EPA guidance. The intended effect of this action is to propose approval of New Hampshire's revised vapor recovery regulation.
Approval and Promulgation of Air Quality Implementation Plans; New Hampshire; Manchester and Nashua Carbon Monoxide Limited Maintenance Plans
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of New Hampshire. This SIP revision establishes carbon monoxide (CO) limited maintenance plans for the City of Manchester, New Hampshire and the City of Nashua, New Hampshire. As part of its limited maintenance plan, New Hampshire will continue year-round CO monitoring at the Londonderry Moose Hill station in Londonderry, New Hampshire with triggers to reestablish CO monitoring sites in Manchester and Nashua if elevated CO levels are recorded in Londonderry. Future carbon monoxide transportation conformity evaluations for Manchester and Nashua will, for the length of their limited maintenance plans, be considered to satisfy the regional emissions analysis and ``budget test'' requirements. This action is being taken under the Clean Air Act.
Greenhouse Gas Reporting Rule: Revisions and Confidentiality Determinations for Petroleum and Natural Gas Systems
The EPA is proposing revisions and confidentiality determinations for the petroleum and natural gas systems source category and the general provisions of the Greenhouse Gas Reporting Rule. In particular, the EPA is proposing to revise certain calculation methods, amend certain monitoring and data reporting requirements, clarify certain terms and definitions, and correct certain technical and editorial errors that have been identified during the course of implementation. This action also proposes confidentiality determinations for new or substantially revised data elements contained in these proposed amendments, as well as proposes a revised confidentiality determination for one existing data element.
