1. Shelbyville KY Stormwater Best Management Practices January 2013 No Symbol Symbol Description Citizens residents and property owners of Shelbyville have the largest impact on the local streams and creeks Most of the creeks drainage channels and stormwater drains are located on private property By eliminating pollution and protecting stormwater quality runoff our streams and creeks will again support fish and other wildlife It is important to protect stormwater quality since most city parks and recreation areas are located adjacent to streams creeks or karst features The City of Shelbyville is required by the Kentucky Division of Water KDOW to reduce various types of pollution KDOW issued a NPDES Phase Il permit to the City of Bowling Green in 2003 Stormwater quality data is reported to KDOW annually Illicit discharge detection and elimination non stormwater discharges is a control measure regulated by the city The principal goal of this BMP is to eliminate all substances liquid or solid that do not belong in stormwater Severe penalties and fines can be assessed for each incident Consult with the City of Shelbyville s Stormwater Ordinance for information regarding allowable and prohibited discharges For more information on illicit discharges to stormwater drainage systems contact the City of Shelbyville Public Works Department or visit the City website at htto www shelbyvillekentucky com Shelbyvi
