Members present: Donna Mankowski (Vice Chair), Dan O'Keefe, Char Jasan, Tom Voll, and Liz Weninger. Others present: Mike Myser (City Council Liaison) Ross Bintner (Water Resources Engineer) CALL TO ORDER II. APPROVAL OF MINUTES A. There were no minutes to approve. III. OLD BUSINESS A. Municipal Separate Storm Sewer System/Storm Water Pollution Prevention Program (MS4 SWPPP) Public Hearing PLSLWD Water Resources Management Plan update Bintner talked about the permit requirements for the following agencies: Stormwater Pollution Prevention Plan (SWPPP), Municipal (MS4), State General Permit to Discharge Stormwater associated (Permit), and Minimum Control Measure (MCM). Bintner noted that in 2009, the City focused on the relationship between regulation and water quality utility and that in 2010, the this presentation is focusing on the legal side of the permits and their relationship to the water quality utility program. The City's goal is to embrace utility management in the future, the effectiveness of the system, and the overall cost efficiency of it. He commented about partnering with the watershed, the county, the township and neighboring cities to align each entity's educational and financial resources to help achieve this goal. He explained that by protecting water quality we are actually protecting the health and welfare of the general public. WENINGER MOTIONED TO OPEN THE PUBLIC HEARING, SECOND BY O'KEEFE. APPROVED 5-0. There were no comments from the public. WENINGER MOTIONED TO CLOSE THE PUBLIC HEARING, SECOND BY JASON. APPROVED 5-0. THE PUBLIC HEARING WAS CLOSED. Weninger asked about the grass clippings and other debris that is going into our lakes and wetlands while Scott County is mowing the boulevards on county roads. She said that is going against everything that the LAC is trying to achieve. She also questioned whether Scott County could stop using sand/salt on icy winter roads. Mankowski suggested that discussion should also be opened with the State of Minnesota about applying sand/salt on TH 13. Mike Myser (City Council Liaison) said that he has met with Scott County representative, Gary Shelton and Commissioner Barb Marschall regarding using other alternatives to sand/salt. Mankowski questioned whether the City's parks maintenance crews have been informed about not cutting grass too short and what they were doing with the grass clippings. She suggested that the Prior Lake Association could write a general article about mowing and grass clippings for Lake Smarts. Bintner said that partnering in education with the various agencies is the real key to controlling water quality whether it is through community events, signs, pamplets, the website, etc. Voll brought up the Dive the Lake Program. He suggested that pictures of the amount of garbage that was brought out of the bottom of the lake in early June be posted on the City's website and in the local paper so residents to see the amount of junk that was retrieved from the lake. B. Street Sweeping - Bintner gave an update on the 319 Clean Water Grant project. The City is partnering with the University of Minnesota on this study and will analyze the water quality benefit received from regular street sweeping that picks up leaves, sand, phosphorous and other debris before heading into the storm water. C. Iron Enhanced Sand Filtration Study - Bintner gave an update explaining with the tests will take place. IV. OTHER BUSINESS -- Dive the Lake Update Mankowski said that this was the fifth year that LAC sponsored the Dive the Lake program. There were 29 divers and they filled up a 5 yard 2 dumpster with various items (eg. anchors, the bottom of a fish house, a boat lift cover, fishing poles, pipes, etc. V. STAFF UPDATE A. 2009 Water Quality Pond Maintenance, Project #09-013 Update - Bintner noted that in 2009 the City did maintenance on six ponds at a total cost of approximately $133,000.00. Those projects are now completed. B. 2011 Water Quality Maintenance and Retrofit Project #11-012 Update - The 2011 project is in the planning stages. The City Council gave their approval to begin surveying and testing. Surveyors will do wetland delineations, testing for contamination, etc at six pond sites. Plans should be finalized by late summer and the project will be bid sometime in Nov/Dec. The contractor will begin work around January. VI. NEW BUSINESS Mankowski talked about zebra mussels in Prior Lake. She said that Gary Montz, Microbiologist with the DNR will be surveying the lake in the late summer or early fall to check the increase of the zebra mussel population. Mankowski noted that residents can help the DNR by informing them when they notice zebra mussels attached to their boats, boat lifts or docks. Bintner suggested linking the DNR's phone number to the homepage of the City's website so residents can report findings directly to the DNR. VII. JASAN MADE A MOTION TO AJOURN, SECOND BY WENINGER.

Attachments: 2009SWPPPWQ.pdf; 2010-06 agenda.pdf LAC, Attached is the SWPPP presentation materials and Agenda for our meeting next week (June 15). I look forward to your questions and guidance on how we manage the Water Quality Utility & SWPPP. Is there any other items we should add? I think a Dive the Lake update may be in order! Remember, we will be holding a public hearing. I've condensed the format from the LAC bylaws and copied it below: 1. The presiding officer announces the agenda item that is the subject of the public hearing. 2. Staff and/or a consultant make a presentation or report on the subject matter of the public hearing. 3. At the conclusion of any presentation or remarks by Staff and/or a consultant, the presiding officer asks the Lakes Advisory Committee members if they have questions of the Staff or consultant. The presiding officer requests a motion and second from a member of the Lakes Advisory Committee to open the public hearing and calls for a vote. 5. The presiding officer declares the public hearing opened, announces the time and then proceeds to ask for citizen input, comments and questions. 6. Members of the public, interested parties or their authorized representatives may address the Lakes Advisory Committee orally. 7. After all persons have been heard, the presiding officer will ask twice whether there are any other persons in attendance who want to be heard on the matter pending. 8. LAC motion and second to close the public hearing. 9. The Lakes Advisory Committee addresses the subject matter through deliberation.
