Below is the abstract of this Final Rule. The official text (PDF) is also available.

EPA is finalizing approval of revisions to the Imperial County Air Pollution Control District (ICAPCD) portion of the California State Implementation Plan (SIP). This action was proposed in the Federal Register on January 7, 2013 and concerns local rules that regulate inhalable particulate matter (PM) emissions from sources of fugitive dust such as unpaved roads and disturbed soils in open and agricultural areas in Imperial County. We are approving local rules that regulate these emission sources under the Clean Air Act (CAA or the Act).
