Operating permits are legally enforceable documents that permitting authorities issue to air pollution sources after the source has begun to operate. This Web site discusses the kind of operating permit (called a title V operating permit) that most large sources and some smaller sources of air pollution are required to obtain. This requirement comes from Title V of the Clean Air Act, as amended in 1990.
Most title V permits are issued by State and local permitting authorities. These permits are often called part 70 permits because the regulations that establish minimum standards for State permit programs are found in the Code of Federal Regulations at 40 CFR part 70. However, the U.S. Environmental Protection Agency (EPA) also issues title V permits to sources in Indian country and in other situations, as needed. EPA-issued permits are called part 71 permits.
