The Idaho Department of Environmental Quality has released the 2026 Idaho Pollutant Discharge Elimination System Program Permit Issuance Plan.
The plan provides the regulated community, United States Environmental Protection Agency and other state, federal, tribal, and interested entities with information on permits being worked on for the next two years. It also prioritizes the facilities with pending permit applications and/or administratively continued permits under the program.
DEQ assumed delegated authority for municipal, nonmunicipal, general, and stormwater permits on July 1st, 2018, 2019, 2020, and 2021, respectively. With that change in authority, all permits for discharges into waters of the United States in Idaho not on tribal land are issued by DEQ, in accordance with the Memorandum of Agreement between the Department of Environmental Quality and EPA.
See DEQ’s Wastewater Permit Options page for more information.
