Hendersonville, TN Environmental Rules: Erosion Control (2026)

Erosion and sediment control on construction sites in Hendersonville is governed by Title 18 (Stormwater) of the Hendersonville Municipal Code plus the TDEC NPDES Construction General Permit TNR100000 (2021 CGP). Any land-disturbing activity of one acre or more, or less than one acre if it is part of a larger common plan of development or sale, requires coverage under TNR100000, a site-specific SWPPP prepared by a Tennessee qualified designer, a Notice of Intent filed with TDEC, and a Notice of Coverage issued before clearing or grading begins. For smaller residential plot plans and minor commercial/industrial sites, the City issues a Standard Erosion Prevention and Sediment Control plan (Revision 7-1-2025) that fixes the BMP package and inspection cadence. Required EPSC measures on covered sites include perimeter silt fence at down-gradient edges, inlet protection at every storm drain and curb inlet, stabilized construction entrances with rock pads to control vehicle tracking, sediment traps or basins sized per the Tennessee EPSC Handbook (effective January 9, 2026), concrete washout containment, dewatering controls, riparian buffer protection along Old Hickory Lake tributaries, and prompt temporary or permanent stabilization of disturbed areas. The SWPPP must remain on site, must be updated with inspection records, and must be available to City and TDEC inspectors. Hendersonville Public Works notes that construction sites can shed '150 to 200 tons/acre-year' of sediment compared to 1.5 tons/acre-year from pastureland, which is why the EPSC inspection program is among the most active components of the MS4.
