## Abstract

EPA is finalizing full approval and limited approval/ limited disapproval of revisions to the Pinal County Air Quality Control District (PCAQCD or District) portion of the Arizona State Implementation Plan (SIP) concerning visible emissions standards, limits on open burning, and carbon monoxide (CO) emissions from industrial processes. For the visible emissions standards and the open burning limits, EPA is finalizing a full approval of portions of those provisions and finalizing a simultaneous limited approval and limited disapproval for other portions. For CO emissions from industrial processes, EPA is finalizing a limited approval and limited disapproval. Under authority of the Clean Air Act as amended in 1990 (CAA or the Act), this action simultaneously approves local rules that regulate these emission sources and directs Arizona to correct rule deficiencies.
