Approval and Promulgation of Implementation Plans; Wisconsin

The EPA is proposing to approve revisions to Wisconsin's State Implementation Plan (SIP) regarding the control of nitrogen oxide (NO X ) emissions. On August 29, 2003, the EPA published a final rulemaking approving the emission averaging program for existing sources subject to the state's rule limiting NO X emissions in southeast Wisconsin. By its submittal dated May 25, 2004, the Wisconsin Department of Natural Resources requested that EPA approve modifications to existing requirements regarding the control of NO X emissions in the Wisconsin SIP. The SIP revisions modify language to clarify which sources are eligible to participate in the NO X emission averaging program. In addition, the revision creates a separate categorical emission limit for new combustion turbines burning biologically derived gaseous fuels. The request is approvable because it meets the requirements of the Clean Air Act. Wisconsin held a public hearing on the submittal on August 6, 2003. In the final rules section of this Federal Register, EPA is approving the SIP revision as a direct final rule without prior proposal, because EPA views this as a noncontroversial revision and anticipates no adverse comments.
