Approval and Promulgation of Implementation Plans Tennessee: Approval of Revisions to the Portion of the State Implementation Plan Regulating Volatile Organic Compounds and Determining General Alternate Emission Standards

Краткое содержание

On June 25, 1992, and March 22, 1993, the State of Tennessee through the Department of Environment and Conservation submitted revisions to its State Implementation Plan (SIP) regarding general definitions, control of volatile organic compounds (VOCs), and general alternate emission standards. On November 5, 1992, and April 22, 1993, the State submitted revisions to the VOC regulations and general alternate emission standards in the Memphis-Shelby County portion of the Tennessee SIP on behalf of Memphis-Shelby County. Since Memphis-Shelby County adopts the State's regulations by reference, the submitted SIP revisions were essentially identical to the regulations in the State's submittal. EPA is approving or conditionally approving revisions to the Tennessee SIP and the Memphis-Shelby County portion of the Tennessee SIP as meeting the requirements of the Clean Air Act as amended in 1990 (CAA). The State and Memphis submittals addressed, or committed to address, all of the deficiencies identified in the State's VOC regulations and documented by EPA in letters to the State dated November 9, 1987, June 10, 1987, and January 25, 1990, and to Memphis- Shelby County dated November 9, 1987.
