Air Quality Permits

DEQ has regional offices to assist facilities with their permits. Contact the regional office that serves your county.
Air quality permits include enforceable conditions with which the owner or operator of a facility must comply. Some permit conditions are general to all types of emission units, and some permit conditions are specific to the source. The permit establishes limits on the types and amounts of air pollution allowed, operating requirements for pollution control devices or pollution prevention activities, and monitoring and reporting requirements.

Electronic copies of Title V Permits are available on DEQ’s website.  

DEQ is currently creating a searchable database for Air Contaminant Discharge Permits that will be available in 2019. Current ACDP permits and annual reports are available through a Public Records Request.

All permits have a section for abbreviations, acronyms, and definitions. Also, the Oregon Secretary of State Administrative Rules provides general air pollution procedures and definitions that apply to all air quality rules.
The following two letters from EPA give DEQ the authority to implement federal air quality standards for hazardous air pollutants and new sources:
