EPA Regulations require certain facilities that emit criteria pollutants or hazardous substances into the air to get a permit before the facility is constructed or goes through significant modifications. Air quality permits are legally binding documents that include enforceable conditions with which the source owner/operator must comply.
Some permit conditions are general to all types of emission units and some permit conditions are specific to the source. Overall, the permit conditions establish limits on the types and amounts of air pollution allowed, operating requirements for pollution control devices or pollution prevention activities, and monitoring and record keeping requirements.
There are two types of permits: construction permits and operating permits. Construction permits are required for all new stationary sources and all existing stationary sources that are adding new emissions units or modifying existing emissions units. EPA regulations define an emissions unit as any part of a stationary source which emits or would have the potential to emit any pollutant subject to regulation under the Clean Air Act.Operating permits (also known as Title V permits) are required for all major stationary sources. Some local agencies also require operating permits for minor sources.
This page is designed to inform about the various types of permits that exist and provide general information on obtaining the appropriate permit for any Region 10 facility.
