STATE REGULATORY AGENCY
In Oklahoma, the counterpart to the U.S. Environmental Protection Agency (EPA) is the Oklahoma Department of Environmental Quality (DEQ). DEQ is responsible for protecting Oklahoma's land, water, and air from pollution. EPA has delegated to Oklahoma the authority to administer and enforce permit programs for air emissions, wastewater and stormwater control, and solid, medical, and hazardous waste management. Oklahoma imposes discharge limits in its industrial stormwater general permits that are stricter than federal limits. In addition to federal rules, the state imposes its own reporting and disposal planning rules for hazardous waste facilities. The federal government regulates workplace safety requirements in the private sector in Oklahoma, and the state regulates workplace safety in the public sector (state and municipal employers).
AIR QUALITY RULES
Oklahoma's air program is shaped by its state implementation plan (SIP), which details basic strategies for implementation, maintenance, and enforcement of the National Ambient Air Quality Standards. As mandated by the federal Clean Air Act (CAA), each state must adopt and submit a SIP to EPA for approval. Oklahoma'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, hazardous air pollutants, new source performance standards, and various other air-related requirements.
DEQ's Air Quality Division is responsible for administering and enforcing Oklahoma's air pollution rules.
