## Abstract

The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the Antelope Valley Air Quality Management District (AVAQMD) and South Coast Air Quality Management District (SCAQMD) portions of the California State Implementation Plan (SIP). These revisions concern particulate matter (PM) emissions from fugitive dust and abrasive blasting. We are approving local rules that regulate these emission sources under the Clean Air Act (CAA or the Act).
