Approval and Promulgation of a Commitment To Adopt a Rule for Reasonably Available Control Technology for Oxides of Nitrogen for Wisconsin

摘要

The USEPA is conditionally approving a revision to the Wisconsin State Implementation Plan (SIP) for ozone. This revision was submitted by the State to satisfy Clean Air Act (Act) requirements for adoption of rules for application of reasonably available control technology (RACT) for oxides of nitrogen (NO x) in the Milwaukee, Kewaunee, Manitowoc, and Sheboygan ozone nonattainment areas in Wisconsin. The Milwaukee area consists of Kenosha, Milwaukee, Ozaukee, Racine, Washington, and Waukesha counties. In this notice, USEPA is acting not on the rules themselves, but on a commitment by the State to submit NO x RACT rules at a later date.
