NPDES Stormwater Discharge Permits -
Construction Activities

On Dec. 15, 2015 DEQ reissued Oregon's general 1200-C and 1200-CN permits for the discharge of stormwater associated with construction activities.

Supporting documents for the modified permits

The National Pollutant Discharge Elimination System (NPDES) 1200-C, 1200-CN and 1200-CA general permits apply to construction activities including clearing, grading, excavation, materials or equipment staging and stockpiling that will disturb one or more acres of land. They also apply to construction activities that will disturb less than one acre that are part of a common plan of development or sale, if the larger common plan of development or sale will ultimately disturb one acre or more. In addition, DEQ may require registration for any other construction activity based on the potential for contribution to an excursion of a water quality standard or potential for significant contribution of pollutants to waters of the state.

General Information: 1200-CN Construction Stormwater General Permit

  • In some local jurisdictions with eligible stormwater programs, qualifying construction activities that disturb less than five acres will be automatically covered under the 1200-CN permit when they receive the local construction permit. In a few jurisdictions, construction activities that disturb less than one acre are automatically covered. Information needed to determine if your project qualifies for the 1200-CN is available below.

    Owners and operators of automatically covered construction activities must comply with performance requirements and other terms of the 1200-CN permit, but do not submit a DEQ application or pay fees to DEQ. Owners and operators must comply with all applicable local code, ordinance and permit requirements. The local jurisdiction will provide a copy of the 1200-CN permit when construction is approved. If you do not obtain 1200-CN coverage through the local jurisdiction, you must register for the 1200-C. The 1200-CN applies only to the jurisdictions listed below. Please read the permit to determine if your project meets all the eligibility requirements.
