EPA is approving revisions to the Tennessee State Implementation Plan (SIP) for ozone. These revisions were submitted to EPA through the Tennessee Department of Environment and Conservation (TDEC) on November 5, 1992, May 18, 1993, and July 6, 1993, for the Nashville nonattainment area and revise regulations for Stage I vapor recovery (Stage I) in the Tennessee SIP and add regulations pertaining to Stage II vapor recovery (Stage II). These revisions regulate gasoline dispensing stations in Davidson, Rutherford, Sumner, Williamson, and Wilson counties. These regulations have been submitted by the TDEC to satisfy the requirement of section 182(b)(3) of the 1990 Clean Air Act, which requires all ozone nonattainment areas classified as moderate or above to require owners and operators of gasoline dispensing facilities to install and operate Stage II vapor recovery systems. The revisions also make minor changes to the Nashville- Davidson County Rules regulating definitions and recordkeeping. The TDEC has also submitted this plan as an integral part of the program to achieve and maintain the National Ambient Air Quality Standards (NAAQS) for ozone. These regulations meet all of EPA's requirements and therefore EPA is approving this SIP revision.
