Enforcement Data - Stationary Sources
Contact
California state law gives the 35 local air districts primary authority to regulate stationary sources for criteria pollutants. CARB has an important role in providing support to districts with training and enforcement. State law also authorizes CARB to review district permitting programs to ensure that they are sufficient to meet state ambient air quality standards, as well as district enforcement programs to ensure that they are reasonable. In addition, CARB has direct enforcement authority, especially over climate programs, many of which impact stationary sources. Stationary source-focused programs in CARB’s Enforcement Division are implemented consistently with legal authority through training and support; conducting analyses of air district rules, regulations, variances, and policies as required by state law; and direct enforcement.
The tables below provide statistics on our stationary source programs. The first table provides the results of the Air District Hearing Board Program as it relates to variances, notices, and abatement orders. In addition, the table provides the results of investigations and inspections under our Landfill Methane Gas Regulation, the Refrigerant Management Program, Sulfur Hexafluoride Regulation, and other stationary sources and equipment inspections. Finally, the table provides results of any mandatory reporting violations. The second table highlights multiagency inspections (the air districts, US EPA, and other state agencies) and the results of those inspections.
