Comparison: State vs. Federal

Rules. Oregon is authorized by the U.S. Environmental Protection Agency (EPA) to administer the federal National Pollutant Discharge Elimination System (NPDES) permit program for wastewater discharges, including permitting authority for stormwater discharges. The state generally follows the federal rules for NPDES stormwater permits and has additional requirements, including application and annual fees for stormwater permits.

Oregon has both individual and general permits for stormwater discharges. A facility may request an individual permit if it exhibits characteristics that are different from those facilities covered by the state's general permit. Examples of different characteristics include operations that are not covered by those in the available general permit, conditions that may affect water quality, or existing stormwater structures. Individual permits tend to take longer to process and have higher fees.

See the national section STORMWATER—GENERAL for more information on the federal program, and the state sections STORMWATER—INDUSTRIAL FACILITIES, STORMWATER— CONSTRUCTION ACTIVITIES, and STORMWATER—MUNICIPALITIES for information on the state requirements for these specific types of stormwater discharges.
