The City of Hendersonville is currently operating under the Phase II National Pollutant Discharge Elimination System (NPDES) General Permit for Discharges from Small MS4's (Permit # :TNS075353). The MS4 Permit cycle is five years, effective from October 1, 2016, to September 30, 2021. The permit allows the municipality to discharge stormwater runoff from municipal drainage systems into waters of the state. The City of Hendersonville is required to implement programs and best management practices that protect water quality and reduce the amount of pollutants entering our water bodies to comply with the Clean Water Act. The permit requires that the City of Hendersonville outline specific programs and best management practices to protect water quality through a Stormwater Management Program (SWMP). The Hendersonville SWMP is required to address stormwater quality through six minimum control measures.
The Hendersonville Stormwater Ordinance outlines the rules and regulations for planning, location, construction, and operation and maintenance of stormwater facilities in the municipality. Tennessee Code Annotated 68-221-1105 provides the municipality with the authority to implement these rules and regulations.
