Basic and General Air Contaminant Discharge Permits

Basic and General Air Contaminant Discharge Permits are established for some of the most common industry types in Oregon. These permits follow the rules contained in OAR 340 Division 200 through 268. Any activity, operation, process or facility found on the list in Table 1, Part A of OAR 340-216-8010 must, at a minimum, obtain a Basic ACDP. Sources found in Part B of the Table may apply for a General ACDP if DEQ has issued one (if it is listed below) and the source qualifies for the permit (review the qualifications listed within the permit).

DEQ's air permits vary in complexity. The simplest type of permit is a Basic ACDP, followed by a General ACDP, Simple ACDP, Standard ACDP, and Title V permit. Any source may elect to obtain a higher-level permit than is required, which can help clarify requirements for sources that are subject to multiple rules or have a variety of equipment subject to regulation.

All air permits require a Land Use Compatibility Statement prior to permit issuance. By law, DEQ must ensure that an operation is complying with local land use jurisdiction prior to issuing a permit. Check with your local city or county planning section/division for further information.

If you have questions about application forms or processes, email your regional DEQ office to a request a pre-application meeting.

For a complete list of forms, visit the AQ Permits webpage. If you have questions about which forms are required, you can call or email your regional DEQ office.

 There are two different General Permits for Metal Fabrication and Finishing facilities. Both permits are for facilities 'primarily engaged' in specific manufacturing or processing activities.

The AQGP-25 is designed for facilities that perform one or more specific activities listed in permit condition 1.1 (e.g., dry abrasive blasting in a vented enclosure that emits specific metal hazardous air pollutants, or spray applied surface coating using paints that contain specific metal hazardous air pollutants). DEQ refers to the AQGP-25 permit as the 'large' metal fabrication and finishing permit.

The AQGP-29 is designed for facilities that are primarily engaged in the same specific manufacturing or processing activities but that specifically do not conduct any of the specific activities listed in permit condition 1.1 (e.g., dry abrasive blasting in a vented enclosure that emits specific metal hazardous air pollutants, or spray applied surface coating using paints that contain specific metal hazardous air pollutants). DEQ refers to the AQGP-29 permit as the 'small' metal fabrication and finishing permit.
