Approval and Promulgation of Air Quality Implementation Plans; Indiana; Revisions to Particulate Matter Rules
On November 27, 2007, Indiana submitted draft revisions to its particulate matter State Implementation Plan (SIP) for sources in Clark, Dearborn, Dubois, Howard, Lake, Marion, St. Joseph, Vanderburgh, Vigo, and Wayne Counties. Indiana supplemented its submittal with a public hearing transcript and additional technical support documents on December 3, 2007, and submitted final, fully adopted revised rules on February 21, 2008. This SIP revision updates facility names, revises formatting, removes sources no longer in operation, and revises some emission limits. Where emission limits increase, the State has included air quality modeling analyses that demonstrate that air quality will continue to be protected. EPA is proposing to approve this SIP revision request.
d-Phenothrin (Sumithrin) Risk Assessments; Notice of Availability and Risk Reduction Options
This notice announces the availability of EPA's risk assessments, and related documents for the pesticide d-Phenothrin (Sumithrin), and opens a public comment period on these documents (Phase 3 of 4-Phase Process). The public is encouraged to suggest risk management ideas or proposals to address the risks identified. EPA is developing a Reregistration Eligibility Decision (RED) for sumithrin through a modified, 4-Phase public participation process that the Agency uses to involve the public in developing pesticide reregistration decisions. Through this program, EPA is ensuring that all pesticides meet current health and safety standards.
National Emission Standards for Hazardous Air Pollutants: Area Source Standards for Plating and Polishing Operations
EPA is proposing national emission standards for control of hazardous air pollutants (HAP) for the plating and polishing area source category. This rule proposes emission standards in the form of management practices for new and existing tanks, thermal spraying equipment, and mechanical polishing equipment in certain plating and polishing processes. These proposed standards reflect EPA's determination regarding the generally achievable control technology (GACT) and/or management practices for the area source category.
Outer Continental Shelf Air Regulations Update To Include New York State Requirements
EPA is proposing to update a portion of the Outer Continental Shelf (OCS) Air Regulations. Requirements applying to OCS sources located within 25 miles of States' seaward boundaries must be promulgated into part 55 and updated periodically to remain consistent with the requirements of the corresponding onshore area (COA), as mandated by section 328(a)(1) of the Clean Air Act (CAA). The portion of the OCS air regulations that is being updated pertains to the requirements for OCS sources in the State of New York. The intended effect of approving the OCS requirements for the State of New York is to regulate emissions from OCS sources in accordance with the requirements onshore. The requirements discussed below are proposed to be incorporated by reference into the Code of Federal Regulations and are listed in the appendix to the OCS air regulations.
