The Department coordinates the statewide air compliance and enforcement activities. The Air Compliance Assurance (ACA) Section promotes air compliance through the department's district offices and the approved local program offices.

ACA oversees air compliance and enforcement data management and provides required data to the US EPA. Responsibilities also include the coordination of air enforcement statewide and conducting special projects in air compliance assurance.

An ongoing ACA project is the Electronic Access System for Inspection Information Retrieval (EASIIR), an application that retains downloaded air compliance data on a rugged portable computer that is taken into the field by the inspector.

EASIIR allows for the capture of inspection observations and results, as well as the subsequent uploading of this information directly into the air database. The application also retains previous inspection history data, eliminating the need for extensive research and data reentry each year.
