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.

Fact Sheet: Applying for the 1200-C Construction Stormwater Permit
This outlines the steps all 1200-C permittees need to take to obtain a valid permit
for construction projects that disturb one acre or more of land. (April 2011)
1200-C Permit fees
- 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
