What is Stormwater?

Stormwater is rain and snow melt that runs off surfaces such as rooftops, paved streets, highways, and parking lots. Stormwater carries sediment, oil, grease, nitrogen, phosphorus, and other pollutants into storm drains and then, untreated, into nearby waterbodies. Because most stormwater drainage systems provide no treatment, preventing contamination of stormwater is crucial to ensure that pollutants do not enter waterways. Improperly managed stormwater runoff is also a leading cause of flooding, which can lead to property damage, cause road safety hazards, and clog catch basins and culverts with sediment and debris.

According to the federal law commonly known as Stormwater Phase II, permits are required for stormwater discharges from Municipal Separate Storm Sewer Systems (MS4s) in urbanized areas and for all construction activities (both inside and outside of MS4 areas) that disturb one or more acres. The New York State Department of Environmental Conservation has developed two general permits as part of the State Pollutant Discharge Elimination System (SPDES) to implement this law in NYS.

About Us

There are 15 designated MS4s located in the Counties of Broome and Tioga that must prepare and implement a stormwater management program to comply with state and federal stormwater regulations. These municipalities recognize that watersheds and separate sewer systems cross municipal boundaries and that collaborative efforts addressing local stormwater issues saves time, money and energy. As a result, the MS4s entered into an agreement to form the Broome-Tioga Stormwater Coalition and work together to address local stormwater issues and meet the state and federal stormwater requirements.
