Comparison: State vs. Federal

Rules. Kentucky has developed a water pollution permitting scheme that follows the federal regulations. The state is fully authorized by the federal government to administer the National Pollutant Discharge Elimination System (NPDES) permit program for wastewater dischargers. In Kentucky, the program is referred to as the Kentucky Pollutant Discharge Elimination System (KPDES). See the national section NPDES PERMIT for additional guidance.

Kentucky's permit requirements are very similar to those under the federal regulations. Like the federal program, Kentucky's regulatory scheme provides for both general and individual permits.

The state is fully authorized to issue and enforce KPDES permits for stormwater discharges and concentrated animal feeding operations (CAFOs), and to administer the KPDES pretreatment program. See the state sections AG WASTE, PRETREATMENT STANDARDS, and STORMWATER— GENERAL for more information.

Administration and enforcement. DEP's Division of Water administers the state's water quality program and issues discharge permits. The Division of Water also enforces permit provisions.
