The IPDES Program and Transfer of the Multi-Sector General Permit

On June 5, 2018, the Environmental Protection Agency (EPA) approved the Idaho Pollutant Discharge Elimination System (IPDES) and authorized the transfer of permitting authority to the state in a phased approach. On July 1, 2021, the Idaho Department of Environmental Quality (DEQ) is scheduled to take on delegated authority of storm water permits from EPA, including the Multi-Sector General Permit for Storm Water Discharges Associate with Industrial Activity. DEQ expects this transfer to be a positive development for environmental and regulated entities.
