Who must comply with EPAs Phase II Stormwater Regulations?
All municipal seperate storm sewer systems (MS4s) that are located in urban areas (as determined by the Census Bureau) must comply with the Phase II Regulations. Suffolk County along with many Towns and Villages must comply with the Phase II Regulations. At this time, the only town in Suffolk County that does not have to institue a stormwater management program is Shelter Island. Although some towns and villages are excluded from having to create a stormwater management program, all constructions sites in New York State that disturb greater than or equal to one acre of land are regulated under the small construction activity portion of Phase II.
