Comparison: State vs. Federal
• Rules. The Texas Commission on Environmental Quality (TCEQ) is responsible for administering and enforcing Texas's air pollution rules. Texas's air program is shaped by its state implementation plan (SIP), which sets forth basic strategies for implementation, maintenance, and enforcement of the National Ambient Air Quality Standards (NAAQS). As mandated by the federal Clean Air Act (CAA), each state must adopt and submit a SIP to the U.S. Environmental Protection Agency (EPA) for approval.
• Administration and enforcement. TCEQ administers and enforces the state's air quality program with assistance from local air pollution control agencies.
TEXAS'S AIR PROGRAM
Texas'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, requirements for nonattainment areas, HAPs, and numerous other air-related requirements.
Areas of the state that do not meet the NAAQS are designated as nonattainment areas. Texas has areas that are classified as nonattainment for PM-10, ozone, and lead. Nonattainment of the NAAQS significantly impacts the permitting procedures and emissions limitations imposed on sources of air pollution.
