## Abstract

EPA is finalizing both an approval and a limited approval and limited disapproval of permitting rules submitted for the Sacramento Metropolitan Air Quality Management District (SMAQMD or District) portion of the California State Implementation Plan (SIP). These revisions were proposed in the Federal Register on May 19, 2011 and concern New Source Review (NSR) and Prevention of Significant Deterioration (PSD) permit programs for new and modified major stationary sources of air pollution. We are approving local rules that regulate these emission sources under the Clean Air Act as amended in 1990 (CAA).
