Public Works Committee 6. 1. Meeting Date: 09/17/2019 By: Bruce Westby, Engineering/Public Works Title: Review Wellhead Protection Plan Part 2 Amendment Purpose/Background: Purpose: The purpose of this case is review the Wellhead Protection Plan Part 2 Amendment in advance of the Public Hearing scheduled for Tuesday, September 24, 2019. Background: The Minnesota Department of Health (MDH) is charged with protecting drinking water sources throughout Minnesota per Minnesota Rules, Chapter 4720, Public Water Supplies, which includes administering the Wellhead Protection Program. The purpose of the program is to prevent contamination of public drinking water supplies by identifying water supply recharge areas and implementing management practices for potential pollution sources found within those areas. Public Water Suppliers, which includes municipalities, are required to maintain a Wellhead Protection Plan, and to amend it every 10 years. City Staff has been working with MDH since March of 2017 to amend the City of Ramsey's Wellhead Protection Plan (WHPP), which was adopted January 4, 2010, and is effective until January 4, 2020. The City's WHPP must be amended by October 6, 2019 to meet the required 10-year update schedule. The WHPP consists of two parts. Part 1 delineates the City's wellhead protection zone and drinking water supply management area (DWSMA), and assesses the vulnerability of our DWSMA and municipal water supply wells. Part 2 includes a potential contaminant source inventory, a potential contaminant source management strategy, an emergency/alternative water supply contingency plan, and wellhead protection program evaluation plan. Part 1 of the WHPP was recently amended and approved by the MDH. A copy of the MDH approval letter, received February 4, 2019, is attached. As required, copies of the amended delineated wellhead protection areas, drinking water supply management areas, and assessments of well and aquifer vulnerabilities were issued to local units of governments wholly or partially within these areas within 30 days after receiving MDH approval of the Part 1 amendment. A copy of this letter with attachments is attached. The City was also required to conduct a public information meeting by April 4, 2019, to present the Part 1 amendments to the public. The public information meeting was conducted on March 19, 2019, as part of the Public Works Committee meeting. To kick the Part 2 amendment process off, City and MDH Staff met on March 28, 2019, to discuss the scope of the required amendments. It was discussed that numerous data elements must be compiled and assessed as related to the management of potential contaminants in the drinking water supply management area that was approved with the WHPP Part 1 amendments. Data elements are pieces of information in the form of maps, lists, records, tables and inventories. Where appropriate, the elements should be reviewed and assessed in terms of their present and/or future implications on the 1) use of the wells, 2) quality and quantity of water supplying the public water supply wells, and 3) land and groundwater uses in the DWSMA. MDH prepared a Scoping 2 Decision Notice after the meeting, which was submitted to the City via email on April 4, 2019. The Notice included a list of required data elements. A hard copy of this Notice, including an attachment noting Potential Contaminant Source Inventory (PCSI) requirements, was received in the mail on April 8, 2019. Copies of the Scoping 2 Decision Notice and PCSI requirements are attached. The MDH provided a deadline of
