DEQ has denied the following seven NWPs: NWP 16 (Return Water from Upland Contained Disposal Areas), NWP 17 (Hydropower Projects), NWP 23 (Approved Categorical Exclusions), NWP 51 (Land-Based Renewable Energy Generation Facilities), NWP 52 (Water-Based Renewable Energy Generation Pilot Projects). and NWP 53 (Removal of Low-Head Dams), and NWP 54 (Living Shorelines). DEQ will provide individual §401 certifications for activities authorized under the NWPs that have been denied on a project-by-project basis.

The 2017 certifications became effective on March 19, 2017.

Regional General Permits

DEQ has certified Regional General Permit–Idaho (RGP-I) authorizing the construction, repair, or replacement of non-commercial piers and floating docks for a joint-use pier or floating dock, marine launching rails, mooring piles, and portable boat lift stations.

DEQ has certified Regional General Permit 27 authorizing the addition of piers and floating docks, marine launching rails, mooring piles, and portable boat-lift stations in Lake Pend Oreille and Pend Oreille River.

DEQ has certified Regional General Permit–Management of Aquatic Invasive Species (RGP-AIS) authorizing the discharge of fill material, structures, and/or work associated with the placement of temporary benthic (bottom) barriers, mechanical harvesting, raking, pulling by hand, and divers using vacuum suction to control growth of invasive, noxious aquatic vegetation as designated by the Idaho State Department of Agriculture and usually associated with docks and swimming areas for safety and navigation purposes. The RGP-AIS also authorizes discharge of fill material, structures, and/or work associated with the placement of temporary benthic barriers and/or divers using vacuum suction to control the spread of nonnative bivalves and gastropods as designated by the Idaho State Department of Agriculture in areas identified with infestations.

DEQ has certified Regional General Permit–Emergency (RGP-E) authorizing the temporary discharge of dredged or fill material to restore, repair, and/or stabilize features that have been damaged, destroyed, or are in imminent danger of failing during emergency conditions, defined as conditions that would result in an unacceptable threat to human life, significant loss of property, and/or significant economic hardship.
