Full Breakdown

All construction disturbing soil must comply with the NYS DEC Standards and Specifications for Erosion and Sediment Control (Blue Book) and the NYS Stormwater Management Design Manual. Projects disturbing 1 acre or more require a SWPPP and coverage under the NYS DEC SPDES General Permit GP-0-20-001. The Dutchess County Soil & Water Conservation District reviews SWPPPs for most towns. Standard BMPs include silt fence along downgradient limits, stabilized construction entrances (50 ft crushed stone), temporary seeding within 14 days of inactivity, and weekly inspections. Hudson River AE-flood-zone towns (Poughkeepsie, Beacon, Hyde Park, Rhinecliff) apply enhanced BMPs through the Hudson River Estuary Watershed Protection Plan. Violations can trigger DEC stop-work orders, town code citations, and NYS DEC civil penalties up to $37,500/day under ECL §71-1929.

Violations & Fines

Town stop-work order plus $250-$1,000/day zoning fines. NYS DEC civil penalties up to $37,500/day under ECL §71-1929 for SPDES violations. Discharge into protected waters: additional penalties under NY ECL Article 17 and federal Clean Water Act citizen suits.
