Item No: 7D Meeting Date: February 27, 2012 Type of Business: Council Business Administrator Review: ____ City of Mounds View Staff Report To: Honorable Mayor and City Council From: Nick DeBar, Public Works Director Item Title/Subject: Second Reading and Adoption of Ordinance 868, An Ordinance Creating a New Chapter to Title 900 Regulating Illicit Discharge and Connections to Storm Drainage System Background/Discussion: The City’s storm drainage system is comprised of over 30 miles of storm sewer piping, 1,500 catch basins and drainage structures, 10 regional ponds, and other components including infiltration basins, underground storage, etc. In order to discharge to these “Waters of the State”, the City is required to maintain a Municipal Separate Storm Sewer System (MS4) general permit. This permit is mandated by the federal regulations under the Clean Water Act and administered locally by the Minnesota Pollution Control Agency. The permit gives owners or operators of municipal separate storm sewer systems approval to discharge stormwater to lakes, rivers, and wetlands in Minnesota. The MS4 permit requires that municipalities develop and implement a Storm Water Pollution Prevention Program (SWPPP), which contains seven Minimum Control Measures (MCMs) that are further broken down into Best Management Practices (BMPS). One MCM is “Illicit Discharge and Detection Elimination” (or IDDE) that mandate municipalities to manage non- storm water discharges to the MS4. These discharges contain pollutants that have negative effects on water quality, natural resources, and wildlife. In order to establish responsibility and legal authority to regulate, monitor, respond, and enforce these illegal (or illicit) discharges and connections, the city needs to adopt a new ordinance. Adopting and enforcing this ordinance is also a BMP requirement under the IDDE MCM. At the February work session, the City Council reviewed a proposed new chapter to the municipal code entitled “Illicit Discharge and Connections to the Storm Drainage System”. This chapter was incorporated into an ordinance, which had a first reading on February 13, 2012. Attached is the final draft of the ordinance with any changes tracked since the first reading. The final version of the ordinance will incorporate these changes if adopted by the City Council. Recommendation: Staff recommends that the City Council provide a second reading and adopt the attached ordinance for City compliance with MS4 storm water permit regulations. If adopted, a summary of the ordinance will be published in the Sun Focus on March 8, 2012 and go into effect 30 days later on April 7, 2012. Respectfully submitted, Nick DeBar - Public Works Director Attachments: • Ordinance 868
