� <br />EN HILLS <br />MEMORANDUM <br />DATE: December 12, 2011 <br />TO: Honorable Mayor and City Councilmembers <br />Patrick Klaers, City Administrator <br />FROM: Kristine Giga, Civil Engineer <br />SUBJECT: Illicit Discharge and Connections Ordinance <br />BackgroundlDiscussion <br />Since 2003, the City of Arden Hills has been required by Federal and State law to have a <br />permit to operate as an MS4 (municipal separate storm sewer system) city. Under this <br />federally mandated storm water program, MS4 cities are required to develop and <br />implement a Storm Water Pollution Prevention Program (SWPPP). The SWPPP must <br />cover six minimum control measures: <br />■ Public education and outreach; <br />■ Public participation/involvement; <br />■ Illicit discharge, detection and elimination; <br />■ Construction site runoff control; <br />■ Post-construction site runoff control; and <br />■ Pollution prevention/good housekeeping. <br />The City has had to identify best management practices (BMPs) and measurable goals <br />associated with each of these six minimum control measures. As required by the MS4 <br />permit, the City submits an annual report to the Minnesota Pollution Control Agency <br />(MPCA) on the implementation of the SWPPP each spring. <br />As listed above, our SWPPP is required to include procedures to detect and remove illicit <br />discharges and improper disposal into the MS4 to the maximum extent practicable within <br />the City. We currently investigate reports of illicit discharges when observed by City <br />staff or reported to the City by concerned citizens. The existing City Code includes <br />language that prohibits illicit discharges and connections to the sanitary sewer system; <br />however, to meet the requirements of the SWPPP, language must also be included to <br />prohibit illicit discharges and connections to the storm sewer system. This proposed <br />ordinance is to address identified deficiencies within our existing City Code to ensure <br />City Council Meeting <br />\�IVletro-inet.us\ardenhills�PR&PW�Engineering\Council Actions�2011\12-12-11Memo IDDEordinance.doc <br />Page 1 of 2 <br />
