of Mounds View Staff Item No: 7C Meeting Date: March 10, 2014 Type of Business: Council Business Administrator Review:G To: Honorable Mayor and City Council From: Nick DeBar, Director of Public Works Item Title/Subject: Resolution 8223, Approving the Wellhead Protection Plan Background: In accordance with Minnesota Rules, Chapter 4720, all public water suppliers are mandated to implement wellhead protection measures through a Wellhead Protection Plan (WHPP). The Minnesota Department of Health (MDH) is in charge of enforcing these rules and notified Mounds View in 2009 that we were included in the next phase of municipalities required to perform this planning work based on our vulnerability to potential contamination. The deadline to complete the WHPP process was October 15, 2013. WHPP is broken into two general parts. Part 1 includes detailed analysis of each well and pumping aquifer characteristics, groundwater flow models, delineating WHP areas including the Drinking Water Supply Management Area (DWSMA), vulnerability assessments, and identifying the types of potential contamination. Part 2 involves inventorying potential sources of contamination and developing management strategies for addressing the potential sources of contamination. Barr Engineering Company was hired by the City to prepare Part 1 of the WHPP and has been coordinating the work with the City's designated Wellhead Protection Manager, Nick DeBar, and MDH staff. The Part 1 Report was submitted to the MDH in December 2011, and subsequently approved in a letter to the City dated February 1, 2012, with a public information meeting conducted on March 12, 2012. Barr was authorized to prepare Part 2 of the WHPP on April 23, 2012 and a draft report was completed and sent to stakeholders on July 22, 2013 for a mandated 60 -day review period. A Public Hearing to review and discuss the WHPP (Part 2) was conducted on September 23, 2013 consistent with the Wellhead Protection Rules (4720.5350, subpart 4). A final report for Part 2 was submitted to the MDH before the October 15, 2013 deadline. Final approval of the WHPP was received by MDH on January 6, 2014 and stakeholders were notified of approval. Discussion: The goals for implementation of the WHPP include the following: Work to maintain or improve the current level of water quality; Work with the surrounding cities to protect the source water aquifers; Provide information and promote activities that protect the source water aquifers and manage the identified potential contaminant sources in the management area; and Continue to compile data to support future wellhead and source water protection efforts. To meet these goals, the following general activities are included in the Wellhead and Source Water Protection Program: Well management, including encouraging proper sealing of unused wells and proper management of existing wells; Potential contaminant source properties, including providing information to property owners that contain Class V wells and storage tanks, and updating and maintaining a database of potential contaminant sources and issues;
