How Utah handles construction stormwater
Construction sites in Utah disturbing one acre or more need coverage under the UTRC00000 Construction General Permit (2024 renewal), administered by Utah Division of Water Quality. The CGP was renewed in 2024 (the prior permit expired June 30, 2024); coverage runs through EPA's NeT-CGP system. Inspect every 7 days with no storm trigger, or every 14 days plus within 24 hours of a 0.5″ storm or snowmelt runoff. Inspections only required during normal working hours.
