## Abstract

EPA is taking direct final action to approve revisions to the Washoe County portion of the Nevada State Implementation Plan (SIP). These revisions concern particulate matter (PM) emissions from fugitive dust sources, such as open areas, unpaved roads, and construction activities. We are approving this local rule that regulates these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).
