WS –Item#1 WORK SESSION STAFF REPORT Work Session Item No.1 Date: October 7, 2013 To: City Council From: Michael Grochala Re: MS4 Update Background The Municipal Separate Storm Sewer System (MS4) general permit is mandated by federal regulations under the Clean Water Act and administered byt the Minnesota Pollution Control Agency. The permit allows for owners of storm sewer systems to discharge stormwater into lakes, river and wetlands provided certain regulatory requirements are met. The City of Lino Lakes has been operating it’s system under a permit issued in 2006. Reissuance of the permit was approved by the state in May of 2013 and went into effect August 1, 2013. Under the permit requirements the City will be required to submit an application for permit reauthorizationby December 29, 2013. The reauthorization will also require the preparation of an updated Storm Water Pollution Prevention Program (SWPPP). The SWPPP is comprised of 6 components, referred to as Minimum Control Measures (MCM’s) that provide for implementation of the permit requirements: 1.Public education and outreach, which includes teaching citizens about better stormwater management 2.Public participation: Include citizens in solving stormwater pollution problems. This includes a required public annual meeting and an annual report. 3.A plan to detect and eliminate illicit discharges to the stormwater system (like chemical dumping and wastewater connections) 4.Construction-site runoff controls 5.Post-construction runoff controls 6.Pollution prevention and municipal “good housekeeping” measures, like covering salt piles and street-sweeping. Over the next 6 to 9 months staff will be working with WSB and Associates to draft the new SWPPP. Jeff Peters (WSB) will be present at the work session to provide an overview of the new permit requirements.
