Proposed Approval of Wisconsin GHG Permitting Approach

EPA has proposed to approve revisions to the Wisconsin State Implementation Plan (SIP), submitted by the Wisconsin Department of Natural Resources (WDNR) to EPA on May 4, 2011, June 20, 2012, and September 28, 2012. The proposed revisions modify Wisconsin's Prevention of Significant Deterioration (PSD) program to establish appropriate emission thresholds for determining which new stationary sources and modification projects become subject to Wisconsin's PSD permitting requirements for their greenhouse gas (GHG) emissions.

WDNR had proposed to defer  the application of the PSD permitting requirements to biogenic carbon dioxide (CO₂) emissions from bioenergy and other biogenic stationary sources in Wisconsin until July 21, 2014. EPA is proposing approval of Wisconsin's revisions because the Agency has made the preliminary determination that these revisions are in accordance with the Clean Air Act (CAA) and EPA regulations regarding PSD permitting for GHGs.
