All discharges to waters of the Commonwealth require a permit through the Kentucky Pollutant Discharge Elimination System (KPDES). Such permits include effluent limitations that are developed from technology-based and water quality-based criteria. The General Procedures for Limitations Development
describes how the Division of Water determines what effluent limitations will be included in a KPDES permit and how those effluent limitations are developed. Water quality based limitations require a determination of whether reasonable potential to exceed a criterion exists. The DOW evaluates reasonable potential using the EPA-approved Permitting Procedures for Determining “Reasonable Potential".
