Air Plan Approval; California; San Joaquin Valley Unified Air Pollution Control District; Ventura County Air Pollution Control District; South Coast Air Quality Management District; Oil and Gas Production; Volatile Organic Compounds
Key claim: The EPA is approving revisions to California’s State Implementation Plan for three air districts regulating volatile organic compound emissions from crude oil and natural gas production facilities under the Clean Air Act.
Abstract
(Rule · Environmental Protection Agency) The Environmental Protection Agency (EPA) is taking final action to approve revisions to the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD), Ventura County Air Pollution Control District (VCAPCD), and South Coast Air Quality Management District (SCAQMD) portions of the California State Implementation Plan (SIP). These revisions concern emissions of volatile organic compounds (VOCs) from crude oil and natural gas production facilities. We are approving local rules that regulate these emission sources under the Clean Air Act (CAA or “Act”).
Why this matters
VOC emissions from oil and gas production contribute to ground-level ozone formation, a key air quality concern in California’s most polluted air basins. EPA approval of these SIP revisions makes the district rules federally enforceable, tightening the compliance regime for upstream oil and gas operators in the San Joaquin Valley, Ventura County, and South Coast. The action is routine but incrementally strengthens the federal backstop on hydrocarbon leak and process emissions in nonattainment areas.
