The criteria for designation as an MS4 is population density and the permit area is a corridor along NYS Route 96 from Eastview Mall to the Victor Farmington Town Line and includes the Village of Victor. However, the entire Town of Victor is covered under MS4 regulations by the adoption of a town-wide drainage program.
Over a five-year period, following notification of coverage, the town and village are required to implement a stormwater management program (SWMP) to satisfy the appropriate water quality requirements of the Environmental Conservation Law and Clean Water Act.
Development within the town and village increases the amount of impervious surfaces, which leads to an increase in runoff and runoff borne pollutants. These pollutants are deposited from the atmosphere, for example they leak from vehicles or are windblown from adjacent areas. During storm events these pollutants quickly wash off and are rapidly delivered to downstream waters. Pollutants of concern include, but are not limited to suspended solids, trace heavy metals, hydrocarbons (oil and grease), nutrients (phosphorous and nitrogen), pesticides, and chlorides (road salt).
The MS4 permit requires the town and village to develop, implement, and enforce a stormwater management program to reduce the discharge of pollutants from the permit area to the maximum extent practicable to protect water quality.
