EPA is making an interim final determination to stay imposition of sanctions based on a proposed approval of revisions to the Imperial County Air Pollution Control District (ICAPCD) portion of the California State Implementation Plan (SIP) published elsewhere in this Federal Register. The revisions concern local rules that regulate inhalable particulate matter (PM<INF>10</INF>) emissions from sources of fugitive dust such as unpaved roads and disturbed soils in open and agricultural areas in Imperial County.
