NECESSITY, FUNCTION, AND CONFORMITY: KRS 224.10-100(5) requires the cabinet to develop and conduct a comprehensive program for the management of water resources and to provide for the prevention, abatement, and control of water pollution. EO 2008-507 and 2008-531, effective June 16, 2008, abolish the Environmental and Public Protection Cabinet and establish the new Energy and Environment Cabinet. This administrative regulation establishes administrative procedures for the issuance of permits for the construction, modification, and operation of facilities authorized by KRS Chapter 224 and establishes conditions for construction of facilities under 401 KAR Chapter 5. The administrative regulation also establishes a schedule of fees to recover the costs of issuance for certain classes of permits. There is not a federal law or regulation relating to construction requirements for wastewater treatment plants or the operational requirements for no discharge operations; therefore, this administrative regulation is not more stringent than the federal requirements.
