Discharge permits in Idaho

4,607Current permits
37Major dischargers
189Individual permits

A major discharger is one EPA rates as significant on volume, toxicity or the water it reaches; the rest are minors. An individual permit is written for one operation, while general permit coverage applies a statewide permit to a site that qualifies for it.

This page gathers Idaho’s current permits three ways below — by the program they are issued under, by the city of the discharge, and by watershed. It names 4 programs, 162 cities and 441 watersheds. Each list says which set it covers.

Every permit’s record

Each of the 4,607 current permits in Idaho has a record page: the permittee, the receiving water, the status and dates, and its effluent limits and exceedances. Each city below lists its own; or every permit in Idaho, A to Z.
