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 nationwide (both inside and outside of MS4 areas) that disturb one or more acres. The Department of Environmental Conservation administers and enforces MS4 regulations in New York State.

MS4 regulated municipalities must prepare and implement a stormwater management program to comply with state and federal stormwater regulations. Watersheds and separate sewer systems cross municipal boundaries so a collaborative effort to address local stormwater issues saves time, money and energy. As a result, our 15 regulated MS4s (13 municipalities and two counties) entered into an agreement to form the Broome-Tioga Stormwater Coalition (BTSC) and work together to address local stormwater issues and meet the state and federal stormwater requirements.  Please visit the Broome-Tioga Stormwater Coalition's official website for more information.

Tioga County's MS4 jurisdictional area is limited to Pennsylvania Avenue in the Town of Owego and the DPW Facility in Catatonk.  Please contact Gary Hammond, Tioga County DPW Commissioner, to report and observed incident of stormwater pollution in the stated areas.

Please browse the Document Library below to access many MS4 Stormwater resources, including the Tioga County and Town of Owego's current Stormwater Management Program Plan.  Please contact Elaine Jardine, Tioga County Planning Director if you have questions regarding this Plan.


The BTSC has also developed an educational campaign "Water from Rain".  You may have seen the television commercials or listened to the radio advertisement.  Please visit to see how you can help to reduce stormwater pollution.
