Abstract
On February 24, 2014, the Wisconsin Department of Natural Resources (WDNR) submitted revisions to its nitrogen oxide (NO<INF>X</INF>) combustion turbine rule for the Milwaukee-Racine former nonattainment area. This revision is contained in "2013 Wisconsin Act 91--Senate Bill 371" which allows alternative NO<INF>X</INF> emission requirements for simple cycle combustion turbines that undergo a modification on or after February 1, 2001, if dry low NO<INF>X</INF> combustion is not technically or economically feasible. This revision is approvable because it provides for alternative NO<INF>X</INF> requirements subject to Environmental Protection Agency (EPA) approval on a case-by-case basis and therefore satisfies the reasonably available control technology (RACT) requirements of the Clean Air Act (CAA).
