## Abstract

EPA is finalizing approval of revisions to the Imperial County Air Pollution Control District (ICAPCD) portion of the California State Implementation Plan (SIP). These revisions were proposed in the Federal Register on May 19, 2010 and concern particulate matter (PM) emissions from beef feedlots. We are approving a local rule that regulates these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).
