Air Quality


An air permit is a legal document that lists what a source must do in order to comply with the state and federal air pollution laws. Air permits may contain emission limitations, work practice standards, record keeping requirements, equipment monitoring requirements, and reporting obligations. The facility's potential to emit (PTE) emissions determines if a facility is classified as major or minor or if the facility has to undergo a major modification.

DHEC's Bureau of Air Quality (BAQ) is responsible for managing South Carolina's air quality permitting program. The BAQ is the EPA delegated authority for stationary source permitting. In this role, BAQ issues construction and operating permits to industrial, commercial, and institutional sources that use or store materials with a potential to emit air pollutants into the air we breathe. These permits are required by Federal and State laws and regulations.

The Engineering Services Division, which administers the permitting process, has four sections: Piedmont Permitting, Sandhills and Pulp & Paper Permitting, Coastal Plains and Power Permitting, and General Permitting and Support. This division's primary function is to review permit applications and issue air quality construction, operating, and registration permits to facilities that emit regulated air pollutants.
