Management of Stark County’s outside air quality is centered around the implementation of the State of Ohio’s air pollution permit system through Ohio EPA. APC's work activities include preparing permits for stationary industrial air pollution sources (which are issued by Ohio EPA). The purpose of the permit is to establish limits and enforceable requirements to ensure the air pollution source does not negatively impact the air quality if it complies with the permit. Air pollution sources include industrial smoke stacks, industrial equipment, gasoline stations, dry cleaners, roadways and other areas that generate dust, odors, or emissions.

There are several different types of Ohio EPA air permits which are dependent on the size and type of facility. Major industrial sources, which are considered high priority facilities (HPF), are required to obtain comprehensive Title V air permits or a Federally Enforceable Permit to Install and Operate (FEPTIO). Minor sources are required to obtain a Permit to Install and Operate (PTIO) or Permit by Rule (PBR). Some sources are small enough to be exempt from permit requirements.

Each potential source of air pollution is required to apply for and obtain an approved Ohio EPA air pollution permit prior to installing and operating. Approval for a permit requires the source to demonstrate it is operating in compliance with all rules and not emitting excess air contaminants. Permit application forms, instructions, and guidance are available through Ohio EPA's website.
