56. REASONABLY AVAILABLE CONTROL TECHNOLOGY STATE IMPLEMENTATION PLAN FOR THE 2015 8-HOUR OZONE NATIONAL AMBIENT AIR QUALITY STANDARD Set a public hearing for April 26, 2023, at 9:30 a.m. to solicit comments on the Reasonably Available Control Technology State Implementation Plan (RACT SIP) for the 2015 8-Hour Ozone National Ambient Air Quality Standard and submittal of the RACT SIP to the U.S. Environmental Protection Agency (EPA) for approval into the Arizona State Implementation Plan . Following the public hearing, the Board is requested to approve submittal of the RACT SIP to the EPA. On November 7, 2022, portions of Maricopa County were reclassified to a moderate nonattainment area with respect to the 2015 8-hour ozone national ambi ent air quality standard. Sections 182(b)(2) and (f) of the Clean Air Act require jurisdictions that are classified as “moderate” or higher nonattainment for ozone to implement reasonably available control technology (RACT) for all sources subject to a Con trol Techniques Guideline (CTG) as well as for all non-CTG major sources of volatile organic compounds (VOCs) or nitrogen oxides (NOx). Non-CTG major sources of VOCs or NOx are those sources that emit, or have the potential to emit, 100 tons per year of VO Cs or NOx. In response to the reclassification, the Maricopa County Air Quality Department (MCAQD) evaluated all local controls (rules and permit conditions) associated with CTG source categories and non-CTG major sources of VOCs or NOx to determine if the controls implemented RACT. The results of the evaluation are detailed in the RACT SIP which MCAQD will submit to the EPA upon approval from the Board. (C-85-23-034-X-00)
