May 23, 2014 Page 2 WHPP, air is climate which determines both water use and aquifer recharge. Earth is a combination of rock, sediment, and soil. Each of these affects Lino Lakes' water supply, either by storing and transmitting the water as an aquifer or by inhibiting flow as a confining layer. Part 1 of the WHPP addressed this subject. Earth is important in a WHPP as it determines how much water is available, where it comes from and how vulnerable groundwater is to contamination from the surface. Finally, Water is the reason for this whole process. The WHPP addresses supply sustainability, mid -scale demand trends, potential quality issues, and comprehensive risk mitigation measures. Part 2 addresses water by combining the Air and Earth subjects (above) with land use, taking inventory of potential contamination sites, surface waters, and evaluating available water supplies in terms of quantity and quality. Once the above data elements are collected and interpreted, impacts of changes in land and water use can be assessed. This will allow issues, problems, and opportunities to be identified and included in the WHPP. Among the issues and problems is a Potential Contaminant Source Inventory (PCSI), which is explicitly identified by the MDH. Another item that the MDH calls out as a separate item is identifying an alternate water supply as part of a Water Emergency and Conservation Plan. This is actually both an issue and opportunity that the Part 2 WHPP will address. Other issues and opportunities that may be included in this WHPP are changes in zoning or land use, well rehabilitation, possible cooperation/collaboration with other water producers, and conflicts with surface water management. Since the Part 2 WHPP establishes action items, there must be a way to measure the effectiveness of these items. Each action item will include a description of how the item will be analyzed and the results fed back to keep the goal relevant. Doing this makes the plan dynamic and more valuable in the long run. A report will be prepared to satisfy the IvIDH reporting requirements for Part 2 of the WHPP. The report and associated GIS files will be delivered in an electronic format on compact disks, per MDH scoping decision. Two CD copies of the draft report and two of the final report will be presented to the City. The Wellhead Protection Rules require that the results of Part 2 of the WHPP to be presented to the public at a public hearing. This proposal includes presenting the results of this work at one public hearing. Work Plan To complete the Part 2 WHPP, we propose to complete the following tasks: Task 1— Data Elements & Assessments During this phase, we will compile the data necessary to complete the WHPP. This includes all of the required elements of the Plan as identified by the MDH in addition to reviewing the WHPP Part 1. During this phase, land use/zoning, and potential contaminant source maps will be completed. Data tables and existing maps will be assembled to complete MDH requirements. The following elements need to be completed: • Physical Environment • Land Use • Water Quantity • Water Quality Task 2 Impact of Changes to Public Water Supply Wells The purpose of this task is to determine whether new potential sources of contamination may be introduced in the future and to identify future actions for addressing these anticipated sources. Expected changes to the physical environment, land use, or ground water will be described that may impact the aquifers serving the City's municipal wells.
