Air Enforcement

Compliance in the air program includes both meeting regulatory requirements and the enforcement actions that ensure those requirements are upheld. The Surveillance Division conducts routine air inspections once a permit is issued, with the frequency and rotation based on the type of air permit and the level of oversight needed for that facility. Enforcement may be initiated when air‑related violations are identified during inspections, but it can also result from agency file reviews, reported incidents, or facility releases that indicate a potential breach of air quality regulations.

About Air Enforcement

The Enforcement Division receives referrals resulting from inspections and/or file reviews performed by Department personnel to determine the degree of compliance with the State of Louisiana Environmental Regulations. The Enforcement Division is divided into four (4) sections. The Air Enforcement Section receives referrals that contain violations of the Air Quality Regulations, including lead and asbestos. These regulations are codified in Title 33 of the Louisiana Administrative Code (LAC). The Air Enforcement Section determines the appropriate course of action based on the findings and nature of the violations noted in the referrals.
