Soil erosion and sediment control required on land-disturbing activities per NYS DEC SPDES general permit (GP-0-20-001) for 1+ acre sites. City enforces stormwater/erosion standards at building permit review.
Sites disturbing one or more acres need a SWPPP prepared by a qualified professional and NOI filing with NYS DEC. Smaller sites must still install silt fence, stabilized construction entrances, and inlet protection per NY Standards and Specifications for Erosion and Sediment Control (2016 Blue Book). The Building Department reviews erosion controls as part of grading/building permits.
Sediment discharge to city storm sewers or streams: stop-work order and DEC referral. Fines up to $37,500/day under state SPDES enforcement.
