Storm Water Permit Program in Indian Country

Permits for Storm Water Discharges

To prevent pollutants in storm runoff from entering surface waters, the federal Clean Water Act requires that stormwater discharges from construction, industrial and municipal sources obtain NPDES permit coverage.

EPA issues NPDES permits in all Indian Country, and works closely with Tribal water quality programs to educate the regulated community about these requirements

The links below describe each permit program in more detail.

• General Permit for Storm Water Discharges Associated with Large and Small Construction Activity
  Note: This Construction General Permit contains special requirements for construction activities occurring within the following reservations: Puyallup, Chehalis, Warm Springs, and Umatilla. See Part 9.F of the permit for more details.

• Multi-Sector General Permit for Storm Water Discharges Associated with Industrial Activities
  Note: Multi-Sector General Permit contains special requirements for industries located with the Puyallup and the Chehalis Reservations. See Part 13.10 of this permit for more details.

• Municipal Permits are required for certain urban communities based on the size of their population.
