Any business or industry (e.g. source) that emits or has the potential to emit pollutants into the air may be required to obtain an air permit from DEQ. DEQ issues permits for new sources, for existing sources, and for sources that are undergoing a modification to industrial processes. If your business resides in Lane County, contact the Lane Region Air Protection Agency for assistance on air permitting questions.
Find the Right Permit Type for Your Business
DEQ designed a step-by-step process to assist a facility in determining if there is a need for an air permit and to identify the correct permit type. DEQ has four types of Air Contaminant Discharge Permits, listed here in order from lowest fees/complexity to highest fees/complexity: Basic ACDP, General ACDP, Simple ACDP, and Standard ACDP.
Review the table of Activities and Sources to determine if your operations fit into any of the defined categories. Please include all combustion equipment (e.g., engines, boilers) located at your facility, as well as their size/rating and fuel type.
If your operations fit clearly into one of the categories, determine which ‘part’ of the list that category is located.
- Part A activities and sources are subject to DEQ’s lowest level air permit, the Basic Air Contaminant Discharge Permit.
- Part B activities and sources may be subject to any one of the next 3 levels of ACDP, General, Simple, or Standard. This depends on the specific activities and complexity of your source.
- Part C activities and sources are subject to a Standard ACDP.
If your operations fit into only category A, go to step 3.
If your operations fit into category B, C, OR multiple categories, go to step 4.
If you only fit into Part A activities and sources, refer to application materials and resources located in Basic Air Contaminant Discharge Permits. Review the application materials and annual reporting form for your specific operation to see what information DEQ will likely require or request when issuing a permit or making a regulatory applicability determination. If your operations fit into multiple categories or in Part B, review General Air Contaminant Discharge Permits to see if a General permit exists for your industry type. If your industry type has a General ACDP, review the application materials and annual report documents to see what information DEQ will likely require when issuing a permit or making a regulatory applicability determination.
If a General ACDP does not exist for your source, you will likely be required to obtain a Simple or Standard permit. DEQ writes these permits for a specific facility based on their operations and processes.
Review Simple and Standard ACDP forms for information requested on these forms that apply to your operations. DEQ will require a form for any emission producing activity and any control device, specifically the 200 and 300 series forms for activities and control devices. The 400 series forms are required for Standard ACDPs.
Once your facility has identified the appropriate permit application, your facility can
- Complete and submit the application materials with applicable fees by following directions on the application documents;
- Contact your local DEQ office with the identified forms and information to schedule a pre-application meeting; or
- Submit the AQ104 Notice of Intent to Construct with all applicable AQ series 200 and 300 forms (and 400 series forms as needed).
*DEQ requires a completed Land Use Compatibility Statement from the local city or county planning department to issue any air permit, except for portable sources. Depending on your area of the state, the time and fees required to obtain this approval from the city or county varies. DEQ recommends beginning this process as early as possible. This website is not a substitute for detailed discussions with DEQ staff or a complete reading of the rules and statutes. Sources that are unsure of the requirements after using this page should contact their closest regional office to speak with their Air Quality Duty Officer.
All required application forms and guidance materials are available on DEQ’s website. The DEQ air permit includes instructions, requirements for operation, fees, emission standards, monitoring, recordkeeping, and reporting.
