White Plains is a regulated MS4 under the NYS SPDES General Permit. Illicit discharges to storm drains (soap, paint, motor oil, grass clippings) are prohibited. Post-construction stormwater controls required for projects disturbing 1 acre or more.
City Code includes an Illicit Discharge Detection and Elimination (IDDE) ordinance. DPW maintains the MS4 separate storm sewer system draining to the Bronx River. Only uncontaminated stormwater may enter catch basins. Car-washing soap, pool discharges (without dechlorination), and construction sediment are illegal discharges. Projects over 1 acre need NOI filed with DEC and a SWPPP reviewed by the city engineer.
Illicit discharge: fines $250-$2,500 per violation plus cleanup costs. Repeat violators face daily escalating penalties.
