At the end of this document is a cost proposal from Bonestroo, Rosene, Anderlik, and Associates, Inc. to assist Farmington in the completion of this Part 2 plan in accordance with Minnesota Rules 4720.5100 to 4720.5590. To date, the City of Farmington has completed their Part 1 Wellhead Protection Plan. The Part 1 plan is a technical document designed to scientifically delineate the lO-year wellhead capture zone of the City's wells. The Part 1 plan also provides an assessment of well vulnerability and the aquifer vulnerability in the' vicinity of this delineation. The results of the delineation and vulnerability assessment were used to create a Drinking Water Supply Management Area (DWSMA), which identifies the portion of the land surf~e to be managed in the Part 2 Wellhead Protection Plan. The DWSMA also identifies which areas are more sensitive to contamination, therefore prioritizing how these areas are to be managed. The Part 2 Wellhead Protection Plan is a document which identifies all known potential sources of contamination to the City's wells, identifies potential changes to the water supply system, outlines goals for the protection of the City's water supply wells, and develops a management plan to achieve or maintain these goals. SCOPE OF ACTIVITIES - PART 2 WELLHEAD PROTECTION PLAN On October 7,2004 a scoping meeting was held with Minnesota Department of Health (MDH) staff. The purpose of this scoping meeting was to review the results of the Part 1 plan and to discuss elements required to complete the Part 2 plan. On October 20, 2004, the MDH issued a scoping letter to summarize the meeting and provide a final outline of required elements for the . Part 2 plan. 2335 West Highway 36 · St. Paul, MN 55113. 651-636-4600 · Fax: 651-636-1311 The following work plan outlines the required elements and summarizes the activities needed to . complete the City of Farmington's Part 2 Wellhead Protection Plan. A. COLLECTION AND ASSEMBLY OF REQUIRED DATA ELEMENTS The collection and presentation of data elements typically comprises 50-60% of the work required to complete the Part 2 Wellhead Protection Plan. While some of the data is available from different sources, significant effort is usually required to compile, field verify, format, and summarize the data is a usable format. 1. DATA ELEMENTS ABOUT THE PHYSICAL ENVIRONMENT. Data elements describing the physical environment typically include a discussion of precipitation, geology, and water resources. Where applicable to the City of Farmington plan, some of this data was already compiled during the Part 1 Wellhead Protection Plan. That data will be summarized for the Part 2 plan, with emphasis placed on specific data elements that may impact the management of the wellhead protection area. The Part 2 plan will go into greater detail to define these data elements required in the MDH scoping letter. 2. DATA ELEMENTS ABOUT LAND USE. Land use data comprises the most extensive area of data collection required for the Part 2 . Wellhead Protection Plan, as this area of data collection includes the Potential Contaminant Source Inventory (PCSI). The PCSI comprises all possible sources of contamination to the aquifer or the City's water supply based on the vulnerability of the aquifer, as identified in the Part 1 plan. The DWSMA identified in the Part 1 wellhead protection plan has variable levels of vulnerability, which requires different levels of effort in compiling the PCSI. As identified I in the scoping letter, the following contaminant sources must be identified for the following levels of DWSMA vulnerability for Farmington's wells: A. Low (or Very Low) Vulnerability areas inside the DWSMA - This area is highlighted in blue on Figure 4 in the Part 1 Wellhead Protection report. For this area, all groundwater wells within the DWSMA must be identified, located, and inventoried. Additionally, all Class 5 injection wells (shallow disposal wells) within the DWSMA must be identified. Class 5 injection wells include automotive disposal systems, large sewer systems (serving 20 or more people or more than one facility), and cesspools. B. Moderate Vulnerability area inside the DWSMA - This area is highlighted in yellow on Figure 4 in the Part 1 Wellhead Protection report. For this area, like the low vulnerability areas, all groundwater wells and Class 5 injection wells must be identified and inventories. In addition, storage tanks within the DWSMA must be . identified, located, and inventoried. Storage tanks include all above ground and underground tanks containing materials which could adversely impact the aquifer. . . . C. High Vulnerability area inside the DWSMA - This area is highlighted in red on Figure 4 in the Part 1 Wellhead Protection report. For this area, like the moderate vulnerability area, all groundwater wells, Class V injection wells, and storage tanks must be identifies and inventories. In addition, all other potential sources of contamination must also be inventoried and identified, including (but not limited to) individual septic systems, hazardous waste generators, storage facilities, feedlots, and turf management sites (agricultural or recreational). This high vulnerability area comprises roughly 75% of the total area within the DWSMA. As such, the complexity of the PCSI should generally be suited to match the overall high vulnerability of the Farmington DWSMA. Some of the PCSI data will be provided by the MDH as a follow-up to the Part 2 scoping meeting. However, a large component of the work in developing the PCSI is finding additional sources not listed on the State's database, verifying the locations of sites listed on the database, determining the status of each site, and updating all information to reflect current conditions. A large block of time is often occupied by expanding on the State's database and doing field verification of all possible potential contaminant sources. In addition, interviews are often held with City staff with the greatest knowledge land use history within the DWSMA. Some time should be set aside by City staff to review the preliminary results of the PCSI and verify locations of certain contaminant sources. While it is possible for the City to partially complete the PCSI at this time and finish the data collection efforts as part of the first year of the plan implementation, it is generally more cost effective to gather as much data as possible at once, instead of re-visiting it in smaller sections over a longer period of time. Having a more complete PCSI will help implementation of the plan go more smoothly and make periodic plan updates easier to accomplish. I The results of the PCSI are used to identify potential threats to groundwater and surface water quality that should be included in the management portion of the plan. The plan will prioritize sites found in the PCSI and develop management strategies for each type of potential contamination source. In addition to the PCSI, land use data elements required in the wellhead protection plan include maps displaying parcel boundaries, political boundaries, public land surveys, comprehensive land use, and the existing zoning. Since much of this information is already available, it is simply included in the plan with comments identifying any areas of concern with regards to managing the wellhead protection area. 3. PUBLIC UTILITY SERVICES. This data collection task usually involves compiling existing maps of transportation routes, storm sewers, sanitary sewers, public water supply systems, pipelines, and public drainage systems. Additionally, records of construction and maintenance of public water supply wells within the DWSMA are typically included. Since much of this data already exists, it is simply attached to the plan along with comments regarding any areas of . concern about these features and how they may impact the quality of the groundwater or surface water. 4. DATA ELEMENTS ABOUR WATER QUANTITY AND QUALITY. Data describing groundwater quantity and quality, where applicable, should be included in the wellhead protection plan. If, for example, Farmington has had prior problems with quality or quantity issues, a discussion of this should be included along with any supporting data. Estimates of future water use should also be included. For wellhead protection areas that have a surface water component or suspected interaction with surface waters, a discussion of surface water quality and quantity (with supporting data) should be included. B. DEVELOPMENT OF WELLHEAD PROTECTION MANAGEMENT PLAN 1. IDENTIFY THE IMPACT OF EXPECTED CHANGES TO LAND AND WATER RESOURCES ON THE PUBLIC W ATER SUPPLY. According to wellhead protection rules, the plan must list and describe expected changes to the physical environment, land use, surface water, and groundwater that may impact . the aquifer(s) serving the public water supply wells. The purpose of this discussion is to determine whether new potential sources of contamination may be introduced to the DWSMA. 2. IDENTIFY ISSUES, PROBLEMS, AND OPPORTUNITIES. \ The wellhead protection plan must identify water use and land use issues or problems related to the aquifers serving the Farmington wells. This section defines the magnitude of the contaminant source management issues in the DWSMA. This section also identifies opportunities to use existing resources and develop relationships with local units of government to effectively manage potential contamination sources. 3. ESTABLISH WELLHEAD PROTECTION GOALS. The wellhead protection plan must establish goals for present and future water and land use. This provides a framework for determining the objectives of the plan and the associated plan of action. The ultimate goal of a wellhead protection plan is to maintain a clean, abundant supply of drinking water for all residents served by the water supplier. To achieve that ultimate goal, several smaller goals should be developed to highlight areas needing the greatest attention. . . 4. OBJECTIVES AND PLAN OF ACTION. This section is the core of the wellhead protection plan, in that it identifies contaminant source management strategies and a plan of action to complete each task. Management strategies can vary widely for each type of potential contaminant source, ranging from non-regulatory activities, such as public education, to regulatory activities such as the adoption of a wellhead protection ordinance. There are dozens of different management options, so the City of Farmington needs to have a plan tailored to best suit its own particular needs and available resources. In addition, objectives and plans of action need to be prioritized to identify the largest threats to the water supply system. Each action item should have a target completion date with the identification of who is responsible to complete each action item. 5. PLAN EVALUATION. The public water supplier must identify a strategy to evaluate the effectiveness of the plan at a regular interval. Minnesota Rules require the plan to be evaluated at a minimum of every 2.5 years or whenever a plan is amended. Plan evaluations should identify successful plans of actions, additional data elements that need refining, and areas of the plan that need to be improved on. . 6. PREPARE CONTINGENCY STRATEGY FOR AN ALTERNATE WATER SUPPLY. The final component to the management plan is the contingency strategy to address the disruption of the water supply due to mechanical failure or contamination. This plan ensures a timely and effective response to minimize any disruption that might take place. Sources of potential disruption and an alternate water supply need to be identified. I Many communities have already submitted Emergency Preparedness and Conservation plans to the Minnesota DNR. Such a plan will fulfill this portion of the wellhead protection. If a plan has not yet been submitted to the DNR, a contingency worksheet is available from the MDH to fulfill this portion of the wellhead protection rule, although it must be site specific and address specific issues that are unique to each public water supplier. Since City of Farmington already has completed an Emergency Preparedness and Conservation plan, this portion of the wellhead protection process has already been fulfilled. The City only needs to provide documentation of the availability of this plan. . C. REVIEW AND APPROVAL PROCESS . 1. INTERNAL REVIEW MEETINGS. Project milestone meetings should be planned throughout the Part 2 planning process. At a minimum, five meetings should be planned: a. Project kickoff meeting (already held with MDH on October 7, 2004) b. Meeting to review draft data elements provided by State (already held October 25, 2004 at Water Board meeting) c. Meeting(s) to review PCSI data. d. Meeting(s) to develop plan goals, objectives, and action items. e. Meeting to review plan before submittal to local units of government. Some of these meetings may take place over the phone, when appropriate. But it is expected that most meetings would take place at the City of Farmington offices. The objective of these meetings is to ensure the plan being developed not only accurately reflects concerns within the DWSMA, but to make sure the plan fits with the City's overall vision of wellhead protection management. An additional meeting may be held, if desired, to present the plan to the Farmington City Council prior to submittal of the plan for local review. . 2. SUBMITIAL OF DRAFf PLAN TO LOCAL UNITS OF GOVERNMENT. According to Minnesota Rules, the draft wellhead protection plan must be submitted to all affected local units of government for a 60-day review and comment period. This review period is to ensure that all local units of government have a chance to provide input before the plan is finalized. The plan shou~d also be made available to the general public for review and comments prior to the public hearing. 3. PUBLIC HEARING. Following the 60-day review period by local units of government, a public hearing is to be held by the City of Farmington to allow the general public and other local units of government a chance to voice their comments and concerns. This public hearing is required by Minnesota Rules and should be conducted as a formal public hearing. 4. SUBMI1TAL OF PLAN TO MINNESOTA DEPARTMENT OF HEALTH. Once the review period and public hearing are over, the plan is then submitted to the Minnesota Department of Health (MDH) for their review and approval. The MDH has 90 days to either approve the plan or to return it to the City of Farmington with a request for additional information. . . D. . PLAN IMPLEMENTATION Once the MDH has reviewed and approved the wellhead protection plan, it is up to the City of Farmington to begin implementation of the plan within 60 days of the notice of approval. Farmington must also notify local units of government of the approval of the plan and the intent to begin the implementation of the plan. As part of our wellhead protection services, we will provide Farmington with a clearly defined schedule of tasks to better aid in implementing the plan. Any public education materials, mailings, or notification letters will be provided (both in paper and electronic formats) to allow Farmington to carry out the implementation with greater ease. This extra step helps to ensure that the plan doesn't "collect dust" and provides a useful resource for City staff. Additionally, a smooth implementation ensures that the Farmington's wellhead protection efforts are viewed favorably by the MDH and other State agencies. E. PLAN UPDATES. Wellhead protection planning is designed to be an ongoing process, so the implementation of the plan is not considered to be the "final" step of the process. As land and water use changes, it will become necessary to update the plan periodically to reflect these changes. Plans are required to be updated under the following circumstances: . 1. Every 10 years to ensure the plan reflects current conditions within the DWSMA. 2. When another well is added to the public water supply system. 3. When the boundary of another DWSMA being delineated overlaps the boundaries of a MDH-approved DWSMA. Adding a new well will not require a full update of the plan for all wells, but will require completing both parts of the wellhead protection processlfor new well(s) added to the DWSMA. \ F. DEVELOPMENT OF WELLHEAD PROTECTION TEAM (OPTIONAL ITEM). When developing the Part 2 Wellhead Protection Plan, the MDH often recommends that the City develop a wellhead protection team with any other affected local units of government. Since the DWSMA for the City of Farmington does overlap into neighboring communities, some interaction with these communities is expected to take place over the course of the project. However, we do not foresee the need to establish a formal wellhead protection team at this time. It is possible that, as the planning process proceeds, that the need for such a team will become clear. At that time, Bonestroo will provide a separate schedule and budget for those activities, should the City of Farmington request .our assistance in forming and managing the wellhead protection team. . COST PROPOSAL . A cost proposal for the completion of the City of Farmington Part 2 Wellhead Protection Plan is provided in Table 1. These costs are designed to reflect the size and complexity of the Farmington DWSMA, along with the various levels of vulnerability within the DWSMA. It is anticipated that the most labor intensive portion of the plan will be the completion of the potential contaminant source inventory, with the development of the management plan being the second largest task. These estimates assume that Bonestroo will undertake approximately 90% of the labor involved in creating the peSI and management plan. At a minimum, at least 10% of labor will be required from City staff to review the PCSI data, provide assistance in locating certain PCSI data points, and provide input towards the creation of the management plan. Cost estimates are not provided for the plan implementation and plan updates, 'as those tasks will be determined by the activities developed within the plan of action or are determined by how rapidly land use and groundwater use changes within the City of Farmington. SCHEDULE A proposed schedule of activities is provided in Table 2. The schedule presented in Figure 2 is designed to submit the plan to the MDH for review before in mid 2005. The MDH recently extended the due date of the Part 2 plan from October 2004 to November 2006. Based on this . schedule presented in Table 2, however, the proposed submittal of the plan to the MDH will occur in August 2005, roughly fifteen months ahead of the newly extended due date. We look forward to continue working with Farmington on their Part 2 Wellhead Protection Plan. If you have any questions about wellhead protection planning, please contact met at (651)604- 4831.
