resourceful. naturally. BARR engineering and environmental consultants April 10, 2019 Mr. Bruce Westby, P.E. City Engineer City of Ramsey 7550 Sunwood Drive NW Ramsey, MN 55303 Re: Part 2 Wellhead Protection Plan Amendment Assistance Dear Mr. Westby: Per your request, this letter presents Barr Engineering's proposed scope of work and cost estimate for preparing the Part 2 Wellhead Protection Plan amendment for the City of Ramsey (City). Our project understanding, proposed scope of professional consulting services, and the assumptions upon which our cost estimate are based are presented below. Project Understanding Wellhead protection planning is ultimately about protecting the City's water supply, thereby protecting the public health. As you know, in the City's Part 1 Wellhead Protection Plan (WHPP) amendment, the area that encompasses the capture zones for the Ramsey water supply wells was delineated. This area is the City's Drinking Water Supply Management Area (DWSMA). Proper wellhead protection planning in the Part 2 WHPP amendment will ensure that the City can manage surface land uses within the DWSMA so as to minimize the potential for those land uses to impact the City's drinking water quality. Barr Engineering's understanding of the project and the scope of professional consulting services for preparing the amendment of Part 2 of the City's Wellhead Protection Plan (WHPP) are described in the following paragraphs. The development of Part 2 of a WHPP must be done according to the Wellhead Protection Rules. Per the rules, Part 2 of the WHPP must include 1) an assessment of data elements relevant to the Plan, 2) an inventory and mapping of potential contaminant sources within the DWSMA that was delineated during development of Part 1 of the Plan, 3) a discussion of issues, problems, and opportunities associated with the DWSMA and the source water aquifers, 4) an assessment of the impact on the public water supply wells of potential future changes in the DWSMA, 5) identification of goals for the Wellhead Protection Program, 6) development of management strategies for addressing the identified potential contaminant sources, 7) a wellhead protection program evaluation process, and 8) an emergency water supply contingency plan. It is our understanding that the Minnesota Department of Health (MDH) held Scoping Meeting No. 2 with City staff on March 28, 2019. The requirements for Part 2 of the WHPP amendment are outlined in the Barr Engineering Co. 4300 MarketPointe Drive, Suite 200, Minneapolis, MN 55435 952.832.2600 www.barr.com
