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.
