700-PM General Permit Revision
Effective May 15, 2015
DEQ regulates the discharge of wastewater from suction dredge and in-water, non-motorized mining operations that recover precious metals or minerals from streambed sediments via the 700-PM NPDES general permit.
The 700PM general permit does not provide coverage for these types of mining discharges:
- suction dredges that exceed 16 horsepower or use suction nozzles with inside diameters larger than four inches in essential salmon habitat water
- suction dredges that exceed 30 horsepower or use suction hoses with inside diameters larger than six inches outside of essential salmon habitat water
- suction dredge discharge to waters listed by DEQ as impaired for sedimentation, turbidity or toxics (other than chlorine)
- mining discharges to water on or adjacent to tribal lands
- suction dredge discharges in State Scenic Waterways
- mining outside the wetted perimeter of a stream in essential salmon habitat
- discharges from highbanker and combination highbanker/suction dredge equipment (you may convert the combination highbanker/suction dredge to a suction dredge, but it must meet definition 15 in the permit.
There may be additional requirements by other local (city, county), state, and federal (BLM, Forest Service, Army Corps) mining and land use authorities (not listed above) that have more stringent requirements than conditions specified in the 700-PM. You must abide by the most stringent requirement and the 700-PM does not exempt your operation from a more stringent requirement.
NOTE: Registration under the 700-PM general permit does not authorize suction dredge mining in areas where mining is prohibited.
