Короткий зміст

The EPA is proposing to approve portions and to conditionally approve other portions of a State Implementation Plan (SIP) revision submitted by the State of Wisconsin on November 15, 1993, if the State submits certain items prior to final action. This revision establishes and requires the implementation of an enhanced motor vehicle inspection and maintenance (I/M) program in the Milwaukee Severe ozone nonattainment area, which has 17 years to attain the National Ambient Air Quality Standards (NAAQS) pursuant to section 181(a)(2) of the Clean Air Act (Act), and the Sheboygan Moderate ozone nonattainment area. This action is being taken under section 110 of the Act. Should the State fail to timely submit the items described below, EPA is proposing in the alternative to disapprove or conditionally approve the SIP.
