## Abstract

EPA is taking direct final action to approve revisions to the Imperial County Air Pollution Control District (ICAPCD) portion of the California State Implementation Plan (SIP). The revisions concern the emission of particulate matter (PM-10) and sulfur compounds into the atmosphere from industrial processes. We are approving local rules that administer regulations and regulate emission sources under the Clean Air Act as amended (CAA or the Act).
