Locations of sites that have obtained Approval Orders from the Utah Division of Air Quality. The Division of Air Quality is responsible for issuing permits for any operation that emits any contaminant into the air. Such permits will often set limits on the amount of a contaminant that can be released, the amount of material that can be processed, or how dark a smoke plume can be. Two different kinds of permits are issued by the Division: Approval Orders and Operating Permits.

Approval Orders are issued by the New Source Review section, and have been required for most new or modified operations since 1969. These permits may include limits on both construction and operation activities. A person must apply for an Approval Order before starting construction or operation of any emitting equipment. An application is made by submitting a Notice of Intent to the Division; a guide for preparing a Notice of Intent is available to help describe the application requirements. There is an exemption available for small sources. The New Source Review section also handles soil remediation projects and sales tax exemptions for the installation of pollution control equipment.
