In Arkansas, the counterpart to the U.S. Environmental Protection Agency (EPA) is the Arkansas Department of Environmental Quality (ADEQ). ADEQ is responsible for protecting Arkansas's land, water, and air from pollution. Arkansas has been delegated authority by EPA to administer and enforce federal regulatory programs for air emissions, surface wastewater effluent and stormwater discharges, groundwater discharges, and solid and hazardous waste management. Various state regulatory requirements are more stringent than corresponding federal requirements.


Arkansas's air program is shaped by its state implementation plan (SIP). The SIP is a plan that details basic strategies for the implementation, maintenance, and enforcement of the National Ambient Air Quality Standards (NAAQS). As mandated by the Clean Air Act (CAA), each state must adopt and submit a SIP to EPA for approval. Arkansas's SIP was officially submitted to EPA in January 1972 and is frequently amended to comply with the 1990 CAA amendments. The SIP focuses on permitting, emissions standards, hazardous air pollutants, and other air-related requirements.

ADEQ's Air Division is responsible for administering and enforcing Arkansas's air pollution rules.
