Oregon Air Permits

Oregon DEQ issues Air Contaminant Discharge Permits (ACDPs) for minor sources and for new major sources/major modifications, plus Title V operating permits for major sources. Which ACDP applies depends on the source category in the Table of Activities and Sources (OAR 340-216-8010, Table 1): Part A sources qualify for a Basic ACDP, Part B for a General, Simple, or Standard ACDP, and Part C must get a Standard ACDP. Permits carry Plant Site Emission Limits (PSELs) compared against Significant Emission Rates (SERs). Many sources need a Notice of Construction even without a permit (OAR Division 210), and every permit needs a Land Use Compatibility Statement. Cleaner Air Oregon adds facility risk assessment for toxic air contaminants. LRAPA permits in Lane County; EPA Region 10 permits in Indian Country and on the Outer Continental Shelf.
