Oregon Air Permitting Issues
Written October 17, 2019
Oregon does have a Title V permit program in place. Sources with the potential to emit more than 100 tons of VOC per year, or 10 tons of one hazardous air pollutant (HAP) or 25 tons of a combination of Hazardous air pollutants are required to apply for a Title V permit.
Air Contaminant Discharge Permits are primarily used to regulate minor sources of air contaminant emissions.
They are required for any new major source or major modification at a major source. There are six forms of ACDPs. A General ACDP is used for an entire source category. Facilities meeting those requirements are then assigned to the permit. Other ACDPs are used for individual facilities. Oregon Title V Operating Permits do not replace requirements in an Air Contaminant Discharge Permit issued to the source even if the ACDP has expired.
For a source operating under a Title V Permit, requirements established in an earlier ACDP remain in effect notwithstanding expiration of the ACDP or the Title V permit, unless a provision expires by its terms or unless a provision is modified or terminated following the procedures used to establish the requirement initially.
