Clean Air Act Operating Permit Program; California; South Coast Air Quality Management District

Issuing agencies

Abstract

The Environmental Protection Agency (EPA) is proposing approval of revisions to the Clean Air Act (CAA or "Act") Operating Permit Program (title V) of the South Coast Air Quality Management District (SCAQMD or "District") in California. Once approved by the EPA, these program revisions will modify the major source title V potential to emit (PTE) thresholds to conform with the recent reclassification of state lands within the Coachella Valley nonattainment area from "Severe-15" to "Extreme" nonattainment for the 1997 8-hour ozone national ambient air quality standards (NAAQS). In the "Rules and Regulations" section of this issue of the Federal Register, we are simultaneously publishing an approval of the District's title V program revisions without a prior proposed rule. If the EPA receives no adverse comment, it will not take further action on this proposed rule.
