Approval and Promulgation of Air Quality Implementation Plans; Colorado; Revised Definitions; Construction Permit Program Fee Increases; Regulation 3
EPA is proposing to approve the two State Implementation Plan (SIP) revision packages submitted by the State of Colorado on August 1, 2007. EPA is proposing to approve the August 1, 2007 submittal revisions to Regulation 3, Part A, Section I where the State expanded on the definition of nitrogen dioxide to include it as a precursor to Ozone. EPA is also proposing to approve numerous housekeeping changes in the August 1, 2007 submittals. In addition, EPA proposes to take no action on several revisions to Colorado's Regulation 3 regarding New Source Review, that are contained in this submittal, where previously proposed, pending or future actions by EPA have addressed or will address these revisions. EPA is also proposing to not act on three provisions in the submittal that are not in Colorado's SIP. This action is being taken under section 110 of the Clean Air Act (CAA).
The Effects of Mountaintop Mines and Valley Fills on Aquatic Ecosystems of the Central Appalachian Coalfield and A Field-Based Aquatic Life Benchmark for Conductivity in Central Appalachian Streams; Release of Final Reports
EPA publically released on April 13, 2011, two final scientific reports assessing the environmental and water quality effects of mountaintop coal mining on Appalachian streams. Both reports, prepared by EPA scientists in the Agency's Office of Research and Development, were strongly endorsed by EPA's Science Advisory Board following an extensive independent peer review. The reports provide valuable scientific information for use by Federal and state agencies responsible for the review of surface coal mining operations under the Clean Water Act. The two reports, entitled The Effects of Mountaintop Mines and Valley Fills on Aquatic Ecosystems of the Central Appalachian Coalfields (EPA/600/R-09/138F) and A Field-based Aquatic Life Benchmark for Conductivity in Central Appalachian Streams (EPA/600/R-10/023F) are available via the Internet at https://www.epa.gov/ncea.
Requests for Modification or Revocation of Toxic Substances Control Act Section 5 Significant New Use Notice Requirements; Revision to Notification Regulations
This direct final rule amends the procedures for requests for modification or revocation of Toxic Substances Control Act (TSCA) section 5 significant new use notification (SNUN) requirements by establishing electronic submission requirements. EPA issued a final rule in the Federal Register of January 6, 2010, introducing electronic reporting requirements for TSCA section 5 submissions and supporting documents. However, the regulatory text inadvertently did not include amendments to the reporting requirements for submissions of requests for modifications or revocations of SNUN requirements. This direct final rule includes the amendment that was originally intended by EPA.
Science Advisory Board Staff Office; Request for Nominations of Experts for SAB Libby Amphibole Asbestos Review Panel
The EPA Science Advisory Board (SAB) Staff Office is requesting public nominations of technical experts to serve on an Asbestos expert panel under the auspices of the SAB to conduct a peer review of EPA's Draft Toxicological Review of Libby Amphibole Asbestos.
Revisions to the California State Implementation Plan, South Coast Air Quality Management District
EPA is proposing to approve revisions to the South Coast Air Quality Management District (SCAQMD) portion of the California State Implementation Plan (SIP). These revisions concern oxides of nitrogen (NOX) and oxides of sulfur (SOX) emissions from facilities emitting 4 tons or more per year of NOX or SOX in the year 1990 or any subsequent year under the SCAQMD's Regional Clean Air Incentives Market (RECLAIM) program. We are approving a local rule that regulates these emission sources under the 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; West Virginia; Permits for Construction and Major Modification of Major Stationary Sources of Air Pollution for the Prevention of Significant Deterioration
EPA is approving a State Implementation Plan (SIP) revision submitted by the State of West Virginia. The intended effect of this action is to approve the inclusion of nitrogen oxides (NOx) as a precursor to ozone in the State of West Virginia for permits for construction and major modification of major stationary sources of air pollution for the prevention of significant deterioration (PSD) areas in West Virginia. This action will also add the Federally equivalent provisions to the rules for the PSD program as they pertain to ``reasonable possibility'' and delete certain references to pollution control projects (PCPs) and clean units (CUs) to make the West Virginia PSD program consistent with the Federal PSD program. This action is being taken under the Clean Air Act (CAA).
