Title V of the federal Clean Air Act reauthorization (1990) requires each state to develop a Permit-to-Operate system and emission fee program for major sources of air pollution. Ohio’s rules for this program became effective in April 1994. The Title V permit for major sources is enforceable by Ohio EPA and U.S. EPA. Major sources must certify compliance with the terms of their permits annually.
Under Title V, major sources are those with a potential to emit:
- 100 tons per year or more of any one regulated pollutant (PM10, nitrogen oxides, sulfur dioxide,
carbon monoxide, volatile organic compounds and lead).
- 10 tons per year or more of any one hazardous air pollutant (HAP), or
- 25 tons per year or more of any two or more HAPs
U.S. EPA currently lists 188 HAPs in Section 112 of the 1990 Clean Air Act.
