This program is now required in Minnesota since the Minnesota Department of Health (MDH) implemented its Wellhead Protection Rules in November 1997. The MDH initiated its Wellhead Protection Program in response to the 1986 Amendments to the Safe Drinking Water Act and MDH's statutory authority is granted in the Minnesota Groundwater Protection Act of 1989. This report is the culmination of the City of Oak Park Height's efforts to adopt wellhead protection planning for its water supply system. The City of Oak Park Heights currently operates two production wells for municipal water supply purposes. Both of the wells are within City limits and are completed in the Prairie du Chien/Jordan Aquifer (OPCJ) system. A detailed description of the geologic and hydrogeologic setting of Oak Park Height's water supply system is presented in Wellhead Protection Area and Drinking Water Supply Management Area Delineations, and Aquifer and Well Vulnerability Assessments(Bonestroo,Rosene, Anderlik, and Associates) which was approved by MDH in March 2002. Additional information about Oak Park Height's water supply system in general is presented in the Water Supply and Distribution Plan, Oak Park Heights, Minnesota(Bonestroo,Rosene,Anderlik&Associates,September 1998). The rest of this report is used to summarize the wellhead protection area delineation analysis, the vulnerability assessment, and to present the contents of the wellhead protection plan. 55-01-118 3 Bonestroo,Rosene,Anderlik&Associates,Inc. 2.0 WELLHEAD PROTECTION AREA AND DRINKING WATER SUPPLY MANAGEMENT AREA The wellhead protection area(WHPA)and drinking water supply management area(DWSMA)delineatio analyses were conducted in accordance with Minnesota Department of Health's wellhead protection rules As a result, the following criteria were considered in making the delineation analysis: 1) the aquifer' hydraulic conductivity,2)the groundwater flow direction,3)the average daily pumping rate from each o the existing wells,4)hydrogeologic boundaries,and 5)time of travel. Each of these criteria were factor- into the development of a groundwater flow model that was ultimately used to conduct the delineatio analysis. The results of this analysis (i.e., the WHPA and DWSMA) are presented in Figure 1 for bot City wells. Additional details on the delineation analysis is presented in Wellhead Protection Area an. Drinking Water Supply Management Area Delineations, and Aquifer and Well Vulnerability Assessments prepared by Bonestroo, Rosene, Anderlik, and Associates (December, 2001). The delineation wa• approved by MDH in March 2002. 55-01-118 4 Bonestroo,Rosene,Anderlik&Associates,Inc. 3.0 VULNERABILITY ASSESSMENT Two separate assessments were undertaken to determine the vulnerability of the city's water supply. The first assessment consisted of an assessment of the vulnerability to contamination of the Prairie du Chien- Jordan aquifer within the identified DWSMA. This assessment was completed according to MDH guidelines and recommended methodology. The second assessment was a well vulnerability assessment for City Well Nos. 1 and 2. The well vulnerability assessment was also completed using MDH guidelines. A description of the two assessments is presented in Wellhead Protection Area and Drinking Water Supply Management Area Delineations, and Aquifer and Well Vulnerability Assessments,prepared by Bonestroo, Rosene, Anderlik, and Associates (December, 2001). The result of the analysis is that the aquifer in the vicinity of the DWSMA and the City wells are both considered vulnerable to contamination. This result drove the need for a detailed evaluation of potential contaminant sources,which is presented later in this report. rj 55-01-118 5 Bonestroo,Rosene,Anderlik&Associates,Inc. 4.0 DATA ELEMENTS The state rules relating to wellhead protection require that wellhead protection plans include specific data elements. Each of these elements was discussed specifically in the second scoping meeting with MDH an. are presented briefly here. 4.1 Precipitation The Oak Park Heights area receives an average of 33 inches of precipitation each year,based on data fro three nearby precipitation gauging stations from 1997 to 2001. About 70 percent of this total usually falls between the period spanning from April through September. See Table 1 for a detailed breakdown o' information gathered from these stations. While more stations exist in the general area, these three represent the nearest three that have the most consistent frequency of measurements from season to season. See www.climate.umn.edu for a more extensive listing of average monthly and annual precipitation data. There exists a potential that precipitation could impact the water quality through stormwater runoff, as there appears to be some hydraulic connection between the aquifer and the surface. The ground-water flow model developed to delineate the wellhead protection areas addresses the rate at which recharge occurs within the aquifer. 4.2 Geology A complete description of geologic conditions in the wellhead protection area is provided in Wellhead Protection Area and Drinking Water Supply Management Area Delineations, and Aquifer and Well Vulnerability Assessments,prepared by Bonestroo,Rosene,Anderlik,and Associates(December,2001), which was submitted to the MDH in January 2002 (4720.5400, subp. 1, item B). In general, it was determined that the OPCJ aquifer is hydraulically unconfined from the St. Croix River to one mile west of the City's wells. The portion of the DWSMA one mile west and beyond is confined.However,there does not appear to be a consistent layer of geologic protection in the confined area of the DWSMA that would, completely prevent contaminants from infiltrating into the aquifer. As a result, a vulnerable classification I was assigned to the aquifer in the area of the DWSMA. 4.3 Soil Conditions Because there is not a consistent protective layer of bedrock or glacial drift in the area of the DWSMA, local soil conditions and soil infiltration characteristics may impact local water quality. The maps from the Washington and Ramsey County Soil Survey showing the area of the DWSMA are included in Appendix A along with the key showing soil types. In general, Soils in the vicinity of the City of Oak Park Heights well field are generally derived from the underlying sandy hills and outwash deposits. These upland soils are well drained, moderately coarse- textured, and belong to the Hayden-Kingsley group. Antigo silt foams and Santiago silt foams are more prevalent as one moves west of the wellfield. These soils are also generally well drained. 55-01-118 6 Bonestroo,Rosene,Anderlik&Associates,Inc. A complete copy of the Washington and Ramsey County Soil Survey can be examined at the county offices in Stillwater, Minnesota or at Bonestroo, Rosene, Anderlik, and Associates, Inc. in St. Paul, Minnesota. 4.4 Water Resources Surface waters within the DWSMA are managed by the Valley Branch Watershed District, the Browns Creek Watershed District,the Middle St. Croix Watershed Management Organization,and the City of Oak Park Heights. Figure 2 shows the political boundaries of the watersheds in and around the DWSMA. Figure 3 shows the regulated wetlands in and around the DWSMA as classified according to type.A map of DNR public waters and public drainage ditches can be viewed at the county auditors office or online at http://www.dnr.state.mn.us/waters/watermgmt section/pwi/maps.html. The connection between the aquifer and surface results in increased potential for contaminants to infiltrate into the aquifer. The area of the WHPA delineation that is in the unconfined area was modified to include any area that drains towards the wellfield or the 10-year capture zone of the wells. This area will also be managed as vulnerable to contamination and expanded the overall area of the DWSMA to what is currently shown in Figure 1. 4.5 Groundwater Quality The quality of water from the City's wells is good with low levels of both iron and manganese. The water is hard at about 210 mg/L or 12.3 grains. In-home water softeners are used to remove hardness for residents who desire softer water. All water quality samples collected by the City of Oak Park Heights for operation of the wells have been reported to the MDH on an ongoing basis. No other sources of water quality data collection are known to be available for the area comprising the DWSMA. 4.6 Groundwater Quantity There are a number of wells in Oak Park Heights and surrounding areas which are covered by state groundwater appropriation permits. The Phase 1 report shows nearby wells and the their volume pumped between 1996 and 2000. Data indicates there are no known well interference problems in or around the Oak Park Heights DWSMA. Data showing all well appropriations permits and volumes pumped can be viewed at the Department of Natural Resources website at http://www.dnr.state.mn.us/waters/watermgmt section/appropriations/wateruse.html. 1 55-01-118 7 Bonestroo,Rosene,Anderlik&Associates,Inc. 5.0 CONTAMINANT SOURCE INVENTORY 5.1 Introduction As part of the City of Oak Park Height's wellhead protection planning process, an inventory of potentia contaminant sources was conducted within the delineated drinking water supply management area (DWSMA). The purpose behind this inventory was to develop a database listing potential sources o i contamination that may affect the public water supply wells for the City of Oak Park Heights. The results of this effort provide the City with information about contaminant sources identified in the DWSMA. Wellhead protection planning strategies can be directed in a manner that will deal with any potential sites before they become a problem or a threat to Oak Park Height's drinking water supply. 5.2 Land Use Following a scoping meeting held with Minnesota Department of Health (MDH) staff in March 2002, MDH and Bonestroo staffproceeded to locate information about land and water use within the delineated 10-year DWSMA for Oak Park Height's wells. Any data which was relevant to the City's wells, the quality of the water being drawn in to the wells, or land and groundwater uses around the wells was considered important in determining any potential threat to the water supply. The following criteria were used: 1. All areas will require that an inventory of wells or other borings or excavations that penetrate bedrock-confining units be conducted; 2. All areas must be evaluated for the presence of sources of fuels, solvents,or other chemicals; and 3. All areas must be inventoried as to the types of land and water uses, as discussed below. Each of these elements is described separately below. Figure 4 shows actual land use designations within the City. 5.3 Wells An important component of the potential contaminant source inventory was the location of any known wells within the DWSMA. Since wells may penetrate confining layers that normally protect an aquifer, they are potential pathways for contaminants to rapidly enter the aquifer. A search for current and i abandoned wells was undertaken for the entire DWSMA. The following sources were used to identify wells in the DWSMA: 1 1. Minnesota Geological Survey's County Well Index(CWI) 2. MDH information about abandoned or sealed wells (to be provided by MDH) 3. Personal interviews with City staff 4. Site reconnaissance 55-01-118 8 Bonestroo,Rosene,Anderlik&Associates,Inc. 5. Aerial photos In general,the information from CWI and the City of Oak Park Heights was used to identify known wells, while the information from the MDH was used to document abandoned or sealed wells. City staff and site reconnaissance was useful in identifying locations for the identified wells. The results of the well search indicated that there are 28 wells currently in use in the DWSMA for the City of Oak Park Heights including the municipal supply wells. A listing of these wells is provided in Table 2 and their approximate locations are depicted in Figure 5. Where well logs are available, these have been provided in Appendix B. Wells that have been abandoned are listed in Table 3 and their locations are depicted in Figure 6. Abandoned well records are provided in Appendix C. A total of three abandoned wells were location in the survey. This represents the wells that were known to be abandoned and may not include wells which are unknown at this time and/or were never properly abandoned. 5.4 Parcel-Specific Land and Water Uses Understanding land use is important in determining key areas for concern in managing a wellhead protection area. For example,knowledge about the location of future commercial development in relation to the DWSMA may reveal a need to closely manage the activity within more sensitive areas. Additionally, any parcels that currently pose a potential threat to the City's water supply need to be highlighted to increase awareness of any concerns. Electronic database and GIS shape files are available on disk. Parcels in DWSMAs have been delineated on Figure 4, according to their current uses. This information was obtained from City of Oak Park Heights staff in personal interviews and from records at Bonestroo, Rosene, Anderlik, and Associates (BRAA), the City's engineering consultant. A large portion of the parcels in Oak Park Height's DWSMA are commercial, including Oak Park Height's Central Business District. For the commercial within the DWSMA,a map(Figure 7)and Table 4 shows the known activity occurring on each parcel. 5.5 Point Sources An important component of the potential contaminant source inventory was to look for any point sources within the DWSMA that might be a threat to the quality of Oak Park Height's water supply. An example of a point source would be an underground storage tank or any facility that stores,handles,or disposes of materials that,if introduced into the environment,might degrade the quality of the water pumped from the aquifer. The first step in the point-source search was to investigate available resources listing potential sites of concern. The MDH provided the City with databases containing information about underground storage tanks,above ground storage tanks,waste generators, spill sites,and facilities with hazardous waste storage in the general area. This information was supplemented with information collected for a phase 1 site assessment that was conducted f o r the City's s central business district(Appendix D).Once this information n was collected, it was reviewed for accuracy and was also reviewed with City staff in order to identify sites that are currently within the delineated DWSMA. A discussion with City staff regarding all commercial 55-01-118 9 Bonestroo,Rosene,Anderlik&Associates,Inc. commercial parcels within the DWSMA revealed that nearly all sites of concern were located in the two databases searched. Additional sites of concern, as identified by the City, are presented separately. A summary of this information is presented in Table 5. In addition,these data have been used to construct the GIS database containing parcel-by-parcel land use codes for the City of Oak Park Height's wellhead protection plan. 5.6 Public Utility Services Another potential source for contaminants within the DWSMA is from infrastructure-related accidents. Roadways,railways,and pipelines are examples of possible transportation routes that may be the site of a leakage or spill. Other infrastructure, such as stormwater retention ponds and storm sewers may divert water to an area with higher surface water infiltration, creating an increased sensitivity to pollution. Highway 36 and Highway 5 (Stillwater Boulevard) are the two main transportation routes through the DWSMA(see Figure 1). There no are active railways or airports within the DWSMA. Figure 8 contains a map showing stormwater drainage within a selected area of the DWSMA. This area represents the main commercial area of Oak Park Heights contained within the DWSMA. Stormwater drainage maps outside this area were not available for this study. Appendix E contains the existing sanitary sewer system map for the City of Oak Park Heights. Northern States Power(NSP)has a buried natural gas pipeline that runs in a north-south orientation along the west side of Oakgreen Avenue. This pipeline does not appear to pose any potential threat to the aquifer,as any leaks in the pipe would result in the gas dissipating in the soil.Any movement of the natural gas would be either upwards through the soil to the atmosphere or laterally along the soil until a natural or manmade outlet was found. Public water supply wells are also components of the public utility infrastructure. The locations of the wells are shown on Figure 1, and construction information is presented in Table 2 (and Appendix B). Currently, the only wells classified as public supply(or municipal) within the DWSMA are the two Oak Park Heights wells. 5.7 Active Sites of Contamination Currently, there are no known active sites of contamination with the delineated DWSMA for Oak Park Heights. While several sites exist within the DWSMA that have the potential to contaminate the OPCJ aquifer,none of these sites is known to currently be leaking or discharging hazardous wastes into the soil or groundwater, nor are there any known sites whose past activity is currently threatening the water quality of the OPCJ aquifer. Should any contamination sites be identified within the DWSMA, they will be prioritized in order of the 1 threat they pose to the City's municipal wells. Site specific soil conditions, geology, surface runoff, and estimated time of travel to the City's wells will be investigated to assess the level of threat to the City's water supply. 55-01-118 10 Bonestroo,Rosene,Anderlik&Associates,Inc. 6.0 PROJECTED CHANGES TO THE ENVIRONMENT, LAND USE, AND SURFACE AND GROUNDWATER 6.1 Changes to the Environment and Land Use The City of Oak Park Heights is growing rapidly. Table 6 shows the population predictions for the City from 2000 to 2040. From the table,the population is likely to triple in the next 40 years. To address this growth rate, new infrastructure, schools, and housing units are being built according to the current comprehensive land use plan. The DWSMA for Oak Park Heights covers areas that are already developed or will be expected to be developed in the coming years. There are, however, few expected changes in land use as a result of projected growth. The DWSMA contains the Central Business District for Oak Park Heights, which includes a mixture of new and old businesses,plus some vacant parcels. The vacant parcels will likely be developed in accordance with current zoning and land use plans(Figure 4)as either commercial property or will be left as open space. These changes will likely alter the water balance slightly on a local basis in that runoff will increase and infiltration decrease. This type of development may produce additional potential contaminant sources within the DWSMA, depending on the nature of businesses that may develop within the Central Business District. For the DWSMA outside of the Oak Park Heights City Limits, the areas reaching into the City of Stillwater are either general business (currently only Firstar Bank in Stillwater occupies this territory) or residential in nature. Zoning of the DWSMA in the City of Grant is not currently defined within this plan, but consists of agricultural(Aamodt's Apple Farm) and recreational(Applewood Hills Golf Course). A small portion of the DWSMA overlaps into Lake Elmo, which is classified as wetland and urban transitional. Finally, the DWSMA overlapping into Baytown Township is currently either residential or agricultural(a tree farm exists on the Bill Keefer property). Growth in Oak Park Heights will eventually require expansion of the current water supply system, a process that will affect groundwater use in the area, and will be discussed in the next section. 6.2 Changes to Surface and Groundwater To meet the increased demand for water in the City,Oak Park Heights has developed a Water Supply and Distribution Plan that maps out necessary system improvements. According to the plan,the pressures of continued growth will require 4 new wells be added to the water supply system in the next 10 years, assuming annexation(s) of parts of Lake Elmo and Baytown Township. The City is planning to concentrate new well development in the Prairie du Chien/Jordan aquifer, although space restrictions may require that the City investigate use of other aquifers or water supply sources. Because each additional well will have an anticipated capacity of approximately 1,000 to 1,200 gpm, substantial additional groundwater appropriations will occur locally. Other high capacity wells may be developed by surrounding communities or by Oak Park Heights within 55-01-118 11 Bonestroo,Rosene,Anderlik&Associates,Inc. the DWSMA of the Oak Park Heights wells,although the City is currently not aware of any plans to do so. The semi-rural areas within the DWSMA are largely occupied, so the likelihood of additional domestic wells being added within the Oak Park Heights DWSMA is low. As indicated earlier, additional development within the DWSMA will alter slightly the water balance because the developed areas will contribute a greater proportion of rainfall and snowmelt to surface water runoff and lesser amounts to infiltration than they do as vacant parcels. 55-01-118 12 Bonestroo,Rosene,Anderlik&Associates,Inc. 7.0 PROBLEMS AND OPPORTUNITIES 7.1 Problems 1. The DWSMA for Oak Park Height's wells is vulnerable to contamination. This conclusion is well established by water chemistry, age dating techniques indicating"young"water, and the geologic setting (i.e., the absence of a fine-grained confining layer in many areas). 2. Portions of the DWSMA include areas of significant commercial activity,some of which represent potential point sources of contaminants. Residential areas of the DWSMA represent potential non-point sources to which the water supply system may be susceptible if lawn care activities are conducted inappropriately or excessively. The number and location of improperly abandoned wells in the DWSMA is not known with a high degree of certainty. . The number and location of active septic systems and inactive, improperly abandoned septic systems within the DWSMA is not known. 7.2 Opportunities 1. The majority of the commercially zoned areas within the DWSMA are within Oak Park Heights City limits and therefore are subject to official zoning controls administered directly by the City. a. Existing land within the DWSMA is largely developed, and principally consists of residential and commercial activities. b. The few parcels that are currently vacant are generally zoned as open space and are compatible with a wellhead protection area and if changes are proposed,will be subject to review by City staff. 2. No heavy industry or manufacturing exists within the DWSMA. 3. Watershed management districts exist to manage surface water drainage for all areas of the DWSMA. 4. Despite the vulnerable setting,the water quality of groundwater historically pumped is very good. 5. Since the DWSMA extends beyond Oak Park Height's borders,an opportunity exists to work with other communities in planning land uses in order to protect the area's groundwater resources. 7.3 Status of Existing Governmental Controls Concerning Water and Related Land Use City of Oak Park Heights Zoning ordinances are the primary means by which the City of Oak Park Heights controls water and land use within the city. The land in the DWSMA is currently zoned as shown in Figure 4. Other official controls available to the City for regulating land use within the DWSMA include conditional 55-01-118 13 Bonestroo,Rosene,Anderlik&Associates,Inc. conditional use permits and other ordinances. Specific ordinances that might be applied for land use and aquifer protection purposes are a shoreland protection ordinance, a septic system ordinance, and an erosion sediment control ordinance. These controls, along with the proposed wellhead protection implementation plan, are anticipated to be adequate in managing the land activities occurring with the DWSMA. Any deficiencies noted will be addressed and corrected in revisions to the wellhead protection plan. Washington County Washington County is in the process of developing a Water Plan,which is expected to be adopted in earl 2003. A draft of that plan is complete and the portion related to wellhead protection(Chapter 5.0) h been provided as Appendix F. Valley Branch Watershed District Valley Branch Watershed District regulates surface water management issues within its boundary thro a permitting process. The Watershed has the authority to review all proposed developments and to ma comments, suggestions, and requirements for rates, volume, and infiltration of stormwater. Along w: their role in issuing permits, the Watershed has created an Alternative Stormwater Best Manageme Practices Guidebook(April 2000),which is used to help guide water management issues in many differer. design scenarios. In general, the Valley Branch plan is up-to-date and is adequate effectively managin surface water issues within its boundaries. Browns Creek Watershed District Brown's Creek Watershed District, like Valley Branch Watershed District, regulates surface water management within its boundary through a permitting process. The Watershed has the authority to review all proposed developments and to make comments, suggestions,and requirements for rates,volume, and infiltration of stormwater. The Watershed has officially adopted their rules and they work with the Washington County Soil and Water Conservation District in the permitting process.In general,the Valley Branch plan is up-to-date and is adequate in effectively managing surface water issues within its boundaries. Middle St. Croix Watershed Management Organization The Middle St. Croix Watershed Management Organization is currently operating under a water plan developed in the mid 1980s. This plan is not likely to be adequate for use in long-term managing of the watershed's resources.A new water plan that will reflect current methodology and management strategies is being developed for the watershed, with an anticipated delivery date of December 31, 2003. Adjacent Communities The City of Stillwater is in the process of beginning their wellhead protection planning. They have held scoping meetings with the MDH to begin the Phase 1 wellhead protection plan,but to date have not yet submitted a wellhead protection delineation for their municipal wells.The relative proximity of Stillwater's 55-01-118 14 Bonestroo,Rosene,Anderlik&Associates,Inc. Stillwater's wells to the City of Oak Park Height's DWSMA has the potential to cause Stillwater's wellhead protection area to overlap that of Oak Park Heights. Any overlap or interaction between the wellhead protection areas, should they occur, will need to be addressed by the Stillwater Wellhead Protection Plan and will also need to be addressed in the future revisions of the Oak Park Heights wellhead protection plan. The City of Lake Elmo has currently not held a scoping meeting with the MDH to begin their wellhead protection plan. They are ranked 806 in the April 3,2002 phasing list published by the MDH. Once Lake Elmo begins wellhead protection planning, the proximity of their wells may or may not have an influence on the Oak Park Heights delineation. There is no ranking for Baytown Township or the City of Grant on the wellhead protection phasing list,as hese communities do not appear to operate public water supply systems. tillwater, Lake Elmo, and Grant can manage their land uses through zoning ordinances. The adequacy and status of these zoning ordinances is currently unknown. Minnesota Correctional Facility(Stillwater Prison) The Stillwater Prison, as a public water supplier, has held a scoping meeting with the MDH and is in the process of developing a wellhead protection delineation for its wells. Staff at the MDH are assisting the Prison with the preparation of this plan and will notify Oak Park Heights of any possible overlap or influence on the City's wellhead protection area. ' State and Federal Regulations Many of the state and federal regulations for potential sources of pollution are design and operation standards. Examples of this are on-site sewer systems, underground storage tanks, and landfills. It should be noted that the state's design and operation standards would be adequate for most contaminant sources within the Oak Park Heights DWSMA. Land use authority that addresses the location of potential sources of contamination within the Oak Park Heights DWSMA rests with local units of government according to Minnesota law. Since the Oak Park Heights DWSMA falls within several local units of government, each local unit of government has jurisdiction over the territory of the DWSMA that falls within its borders. State agencies also have permitting authority for certain activities that may also affect the wellhead protection area. The Department ofNatural Resources is in charge of reviewing and issuing appropriation permits for water users expecting to pump more than one million gallons per year(or 10,000 gallons per day)from groundwater aquifers or surface bodies of water. The MDH issues well construction permits and is in charge of public water supply quality monitoring, in addition to overseeing the wellhead protection program. Any of the these permitted activities which have the potential to affect the wellhead protection delineation and/or the quality or quantity of Oak Park Height's water supply should be reviewed by the respective state agency before a permit can be approved. 55-01-118 15 Bonestroo,Rosene,Anderlik&Associates,Inc. 8.0 WELLHEAD PROTECTION GOALS, OBJECTIVES AND IMPLEMENTATION PLAN Goals and objectives have been developed based on the results of the vulnerability analysis,the results of the potential contaminant source inventory,and local geologic conditions.In general,goals and objectives are ranked in order of priority. 8.1 Goals The following goals form the framework within which the information generated during delineation a source inventory activities is evaluated and upon which the planning activities are based: 1. To continue to provide high quality water that meets state and federal drinking water standar 2. To develop the water supply system and land use activities with aquifer protection a consideration. 3. Practice prevention strategies for properties containing potential contaminant sources to avc. adversely impacting the quality. 4. To work cooperatively with other nearby local units of government(Watershed Districts(WD Water Management Organizations(WMOs),Washington County,adjacent communities,and s agencies) on regional aquifer protection actions. 5. Manage surface water flow and infiltration with an appreciation of the vulnerability of the city' DWSMA. 6. Build awareness of wellhead protection goals among and disseminate information about wellhead protection plan implementation to the city's staff, residents, and business community. 7. Practice prevention strategies for properties containing potential contaminant sources to avoid adversely impacting the quality. 8.2 Objectives To meet these goals, the following specific objectives were developed: 1. Evaluate the potable water quality monitoring strategy used for the water supply system to ensure that not only is it consistent with federal and state requirements but also that it takes into account local conditions. 2. Encourage residential property owners to minimize reliance on lawn chemicals. 3. Develop and implement an aquifer management plan to monitor known sources of contamination and to identify new ones. 4. Educate owners of properties containing potential contaminant sources (underground storage tanks, etc.) of the importance of spill prevention. 5. Be involved in the development and/or implementation of surface and ground-water planning activities for Washington County and applicable WMOs,WDs, and adjacent communities to help manage surface water flow and infiltration issues. 6. Make a commitment to manage abandoned wells effectively by making sure they are sealed properly, as appropriate. 7. Initiate a septic system inventory. 55-01-118 16 Bonestroo,Rosene,Anderlik&Associates,Inc. 8.

Figure 1 depicts the general location pf the property. Figure 2 depicts the layout of the site. The property consists of approximately 106 acres of land bounded by 60th Street and Highway 36 on the north, Oakgreen Avenue on the east, 58th Street on the south, and Norell Avenue and a field on the west. The majority of the Property is undeveloped, with areas of woodland, wetland, and • meadow. Commercial development is concentrated along 60th Street and along Norell Avenue and includes the following businesses: McCormack's Furniture, Eagle's Club,two buildings of unsigned and unknown occupancy, WalMart, Gardy's Cycle/Sports, Jerry's Auto Body/Detail, Applebees, Stillwater Glass, St. Croix Valley Dental, Wallace and Lawrence Chiropractic Clinic, Broaster Line Equipment Company, Hall Family Chiropractic Clinic, Total Pool Company, Chamberlain Window Fashions, and Why USANalley Realty. Two additional businesses, Stillwater Auto Parts and Towing (a scrap yard) and Greenbriar Landscaping Company are located in the central portion of the property, with an access driveway from 60th Street. Residential properties include Pondview - Condominiums and one residence off of 60th Street, five residences along Oakgreen Avenue, and two in the central portion of the property, near the Stillwater Auto Parts and Towing property. A barn and silo are also located in this area. Graded areas are present along 58th Street in the southern portion of the property. These areas are assumed to be related to construction of residential • housing south of 58th Street and/or preparation of the subject property for development. Prior to the current commercial and residential development of the property,the.land was used agriculturally or remained undeveloped. Four of the on-site businesses (Hall Family Chiropractic Clinic, Jerry's Auto Body/Detail, Gardy's Cycle/Sports, and St. Croix Valley Dental Center)were identified as small quantity hazardous waste generators. A fifth property (Haase Farm) was identified as a small quantity hazardous waste generator with an address that appears to place it within the site boundaries. According to regulatory information received for this project, violations have not been reported at the businesses or the farm. 1 Utilities available to the property include natural gas, electricity, telephone, cable, and City sewer and water service. However, Stillwater Auto Parts and Towing uses a septic system which is reported to be malfunctioning. A trench has reportedly been excavated to prevent back-up of sewage into the basement of the building. During the reconnaissance, flow was observed in the trench. An electrical easement, owned by Northern States Power Company extends through the I central portion of the property in an east-west direction. Electrical towers, high tension power lines, 1 and an electrical substation are present within the easement. This Phase I Environmental Site Assessment was performed in conformance with the scope and limitations of the American Society of Testing and Materials Standard Process E 1527-97. This Phase I Environmental Site Assessment has revealed no evidence of Recognized Environmental Conditions (RECs) in connection with the property, except for: REC 1. An area of dead grass off the northeast corner of the electrical substation, indicating a suspected release of herbicide. REC 2. Reported release associated with a current or former underground storage tank at the Stillwater Auto Parts and Towing property. Information related to this incident and the cleanup that reportedly occurred could not be located. REC 3. Presence of a large amount of debris and scrap vehicles at the Stillwater Auto parts and Towing property; staining was also visible in some areas of the property. REC 4. Trenched and overland flow of raw sewage at the Stillwater Auto Parts and Towing property due to a malfunctioning septic system. RECOMMENDATIONS Based on the findings and conclusions of this Phase I Environmental Site Assessment, Northern Environmental recommends the following: REC 1. A soil and/or water sample should be collected from the area of the dead grass and should be analyzed for herbicide contaminants. REC 2. - A soil and/or water sample should be collected from the area of the former underground storage tank and should be analyzed to determine if subsurface impacts related to the release incident are present. REC 3. Soil and/or water samples should be collected from multiple areas of the Stillwater Auto Parts and Towing property, including heavy debris areas in the southwestern portion of the property, the area near a circular concrete pad, and areas of visible staining. Because the whole property has been utilized as a scrap yard and it is not known where removal of fluids and dismantling of vehicles occurred, borings should be spaced over the entire property. In addition, the large amount of debris observed at the property should be removed and disposed of properly. REC 4. The septic system should be repaired or should be permanently removed from service and properly abandoned in accordance with Minnesota Department of Health regulations. 2 In addition, small the reconnaissance of debris past site should noted in or near some should activities or potential oft off-site s and posed of or the woo 0 be reviewed drs wooded areas of the properly and the need for sources o f contamination p openy.

It is intended to permit a user, such as the City of Oak Park Heights, to satisfy one of the requirements to qualify for the innocent landowner defense to the Comprehensive Environmental Response, Compensation, and Liability Act(CERCLA) of 1980. This study is meant to constitute appropriate inquiry into the previous ownership and use of land at the Property, consistent with good commercial or customary practices to identify recognizable environmental conditions. 'This ESA uses reasonably ascertainable data to identify hazardous substances or petroleum products at the Property, which may indicate a recent release, past release, or a material threat of a'release in structures at the Property, or into the soil, ground or surface water at the Property. This report describes the methods used to conduct the study, summarizes the study findings, discusses the significance of these findings, and assesses the need for additional studies which may be required to better characterize potential identified environmental concerns. 2.2 Special Terms and Conditions This Phase I ESA conforms to standards described by the American Society for Testing and Materials (ASTM),specifically to the ASTM Standard Practice for Environmental Site Assessments; Phase I Environmental Site Assessment Process E 1527-97. Work on this assessment was authorized on April 26, 2000. 2.3 Limitations and Exceptions of Assessment Limitations of this Phase I ESA include: 1) The interiors of the following commercial businesses were not inspected: Applebees, WalMart, McCormack's Furniture, Eagles Club 94, and Cool Balloons. 2) The interiors of the structures at Stillwater Auto Parts and Towing, Greenbriar Landscaping Company, and St. Croix Valley Dental were not accessible. 3) Portions of the ground surface at the former Stillwater Auto Parts and Towing property were obscured by the presence of numerous junked vehicles and large piles of debris. 4) Portions of the ground surface at the property were obscured by the presence of dense vegetation and/or wetland. S:IPROJIOPM54340PH PH1.WPD 4 Consistent with the scope of ASTM E 1527-97, the scope of this Phase I ESA does not include the following: 1) Lead paint survey or sampling 2) Radon survey or sampling 3) Polychlorinated biphenyl (PCB) survey or sampling 4) Wetland or protected water evaluation _ 5) Feasible remedial alternatives or response action 6) Any regulatory agency response 7) Evaluation of asbestos-containing materials 8) Assessment of drinking water quality 2.4 Methodology The Phase I ESA conducted for the Property consisted of four tasks: 1) Records Review 2) Interviews 3) Site Reconnaissance 4) Data Evaluation and Report Preparation Methods utilized to perform each of these tasks are described below. • 1) Records Review The Property was reviewed to familiarize and orient important site and local features to available maps, photos, and other information. Local physiography, geology,and hydrology were evaluated by reviewing publications and topographic maps available from the United States Department of Agriculture (USDA), the United States Geological Survey (USGS), and/or the Minnesota Geological Survey (MGS). Aerial photographs, Sanbom Fire Insurance Maps, and/or historical topographic maps were analyzed,when available,to help determine historical land use. Standard environmental records, as described below, were reviewed by a contract environmental records data base company. S:IPROJIOPHR54341OPH PHI.WPO 5 Sites identified by the United States Environmental Protection Agency(EPA) in the following federal databases were compared to the Property location: National Priorities List(NPL), or Superfund; Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS); Emergency Response Notification System (ERNS); Resource Conservation and Recovery Information System (RCRIS): Hazardous Waste Treatment, Storage, and Disposal Facilities (RCRIS-TSD); Large Quantity Hazardous Waste Generators (RCRIS-LG); Small Quantity Hazardous Waste Generators (RCRIS-SG); and No Further Remedial Action Planned Sites (NFRAP). Sites documented by the Minnesota Pollution Control Agency (MPCA) in the following state databases were identified and compared to the Property location: reported resolved and unresolved hazardous material spills(Spills)and leaking underground storage tanks (LUSTs); active and inactive registered aboveground and underground storage tanks (ASTs and USTs); Minnesota Agricultural Chemical Spills (MN AG SPILLS); voluntary investigation and cleanup VIC Minnesota Superfund List or Permanent List of Priorities (SHWS); and Solid Waste Disposal Facilities (SWF/LF). A number of other lists not required by ASTM Standards were searched. Information regarding sites identified within. the government environmental database search is presented in Section 4.1.

Northern Environmental has reviewed this list and where possible, has identified the locations of these sites. Orphan sites with identified locations within the ASTM designated search radii were then incorporated into the total number of located sites, presented in Section 4.1. S:IPRO.AOPH15434 OPH PHI.WPD 6 2) Interviews Personal interviews were conducted with representatives of the Property, as well as city, county, state and/or township staff regarding historical land use, hazardous substance or petroleum product use,and property characteristics relevant to the Property and surrounding area. 3) Site Reconnaissance The Property was inspected by Northern Environmental personnel on May 2 and June 14, 2000. Geologic, hydrologic and topographic conditions were observed and recorded. Interiors and exteriors of buildings were observed. Potential public or private thoroughfares, potable water supplies,sewage disposal systems, heating/cooling systems, drains or sumps, storage tanks, odors, pools of liquid, drums, unidentified substance containers, unusual electrical and hydraulic equipment, hazardous substances and petroleum products, pits, ponds, lagoons, and solid waste disposal areas observed,were noted and recorded. Areas which exhibited characteristics such as surface staining, stressed vegetation, or which were found to be littered with debris were evaluated and recorded. Obvious nearby off-site potential sources of hazardous substances or petroleum products were also noted. A general description of the Property and adjacent properties was compiled from these observations. 4) Data Evaluation and Report Preparation Data collected during all portions of the Phase I ESA were evaluated, collated and assembled into the following report.

S:IPROJIOPH1543410PH_PH1.WPD 13 4.3 Historical Land Use Information DATE USE SOURCE 1938 Roads are visible in the approximate locations of Highway 36 along the Aerial Photograph northern boundary of the property and Oakgreen Avenue along the eastern boundary of the property. Most of the property is in agricultural use. A farmstead with several structures is visible in the central portion of the property, in or near the current location of the Stillwater Auto Parts and Towing property. An access road is visible extending from Highway 36 down through the western portion of the property. A small wetland is visible in the central portion of the property. 1957 Two small structures(apparent residences)are visible along Oakgreen Aerial Photograph Avenue and three small structures are visible along Highway 36. The access road extending through the western portion of the property is not visible. Other site conditions appear similar to those observed in the previous photograph. 1966 The quality of this photograph is poor. Three structures are visible in the Aerial Photograph northwest corner of the property,in the approximate location of the Eagles Club. Indications of grading activity are visible in this area and to the west of the buildings. An additional two structures(apparently associated with residential use)are visible along Oakgreen Avenue. Access roads or driveways are visible in the northeastern corner of the site;this area may be under construction. Several structures are visible on the Stillwater Auto Parts and Towing property;a large amount of what could be scrapped vehicles is visible scattered about on this property, including next to the small wetland. The rest of the site appears to • remain in agricultural use and conditions are similar to those previously described. 1978 A road in the location of 60th Street is visible along the northern property Aerial Photograph boundary. Four buildings are visible off of 60th Street in the current locations of Jerry's Auto Body/Detail and Gardy's Cycle/Sports. Several vehicles appear to be present at these businesses,as well as in the area of the Eagles Club property. A building in the current location of McCormack's Furniture and another smaller structure are visible west of the Eagles Club. Three structures are visible off of 60th Street in the current locations of Stillwater Glass, Broaster Line Equipment Company, and St.Croix Valley Dental and Wallace&Lawrence Chiropractic Clinic. Three structures are visible in the northeastern corner of the property, in the area of Hall's Family Chiropractic Clinic. An additional two residences appear to be present along Oakgreen Avenue in the southeast corner of the property. A wooded area and a pond are visible in the southeastern portion of the property. Debris and/or scrapped vehicles appear to be more widespread at the Stillwater Auto Parts and Towing property. A cylindrical structure is visible southwest of the barn. The top of the structure appears to be an inverted cone-shape,indicating it may be a grain storage bin or silo. The remaining areas of the property appear to be fallow fields or agricultural cropland. S:IPROJ\OPH1543410PH PH1.WPD 14 1987 An additional small structure is present between the Eagles Club building Aerial Photograph and the McCormack's Furniture building in the northwestern corner of the property. Fewer vehicles are present at these properties than previously observed. Two buildings are visible in the area of the current Pond View Condominiums complex in the northeastern corner of the property. Oakgreen Avenue and 60th Street have been realigned to their current locations. The wetland previously observed in the central portion of the property,at the Stillwater Auto Parts and Towing property is no longer • visible. What appears to be debris and scrapped vehicles cover the entire area. A small wooded or wet area may be present in the southwest corner of the Stillwater Auto parts property. Other conditions at the property are similar to those described previously with agricultural or fallow fields and small wooded areas in the remaining areas. 1990 The quality of this photograph is poor. Site conditions appear similar to Aerial Photograph those described in the 1987 photograph. An unimproved road is visible extending from the area of Jerry's Auto Body/Detail down through the western portion of the site. The amount of debris and scrapped vehicles visible at Stillwater Auto parts and Towing appears to be somewhat less than previously observed, but is still distributed over much of this property. 1967 Thirteen structures are depicted on the topographic map. Five Topographic Map correspond to residences currently located along Oakgreen Avenue;one corresponds to a residence currently located off 60th Street;three are located in the northwestern portion of the property, in the current location of the structures at McCormack's Furniture and the Eagle's Club;and four are located in the central portion of the property, in the current area of the residences, barn,and Stillwater Auto Parts and Towing property. The electrical easement is depicted extending east-west across the central portion of the property. Highway 36 and 60th Street are depicted along the northern boundary of the property;Oakgreen Avenue is depicted along the eastern boundary of the property,in a slightly different alignment than is current. A driveway to the cluster of buildings at the Stillwater Auto Parts and Towing property is also depicted. Two small depressions appear to be present in the northeast corner of the property. 1972(photo- Site conditions are the same as previously described for the 1967 map.

S:PROJ1OPH1543410PH_PHI.WPD 23 6.0 FINDINGS AND CONCLUSIONS Northern Environmental has performed a Phase I Environmental Site Assessment of the Proposed Central Business District Area at Highway 36 and Oakgreen Avenue in Oak Park Heights, Minnesota. The property consists of approximately 106 acres of land bounded by 60th Street and Highway 36 on the north, Oakgreen Avenue on the east, 58th Street on the south, and Norell Avenue and a field on the west. The majority of the Property is undeveloped, with areas of woodland, wetland, and meadow. Commercial development is concentrated along 60th Street and along Norell Avenue,and includes the following businesses: McCormack's Furniture, Eagle's Club, two buildings of unsigned and unknown occupancy, WalMart, Gardy's Cycle/Sports, Jerry's Auto Body/Detail, Applebees, Stillwater Glass, St. Croix Valley Dental, Wallace and Lawrence Chiropractic Clinic, Broaster Line Equipment Company, Hall Family Chiropractic Clinic, Total Pool Company, Chamberlain Window Fashions, and Why USANalley Realty. Two additional businesses, Stillwater Auto Parts and Towing (a scrap yard) and Greenbrier Landscaping Company are located in the central portion of the property, with an access driveway from 60th Street. Residential properties include Pondview Condominiums and'one residence off of 60th Street, five residences along Oakgreen Avenue, and two in the central portion of the property, near the Stillwater Auto Parts and Towing property. A barn and silo are also located in this area. Graded areas are present along 58th Street in the southern portion of the property. These areas are assumed to be related to construction of residential housing south of 58th Street and/or preparation of the subject property for development. Prior to the current commercial and residential development of the property,the land was used agriculturally or remained undeveloped. Four of the on-site businesses (Hall Family Chiropractic Clinic, Jerry's Auto Body/Detail, Gardy's Cycle/Sports, and St. Croix Valley Dental Center)were identified as small quantity hazardous waste generators. A fifth property (Haase Farm) was identified as a small quantity hazardous waste generator with an address that appears to place it within the site boundaries. According to regulatory information received for this project, violations have not been reported at the businesses or the farm. Utilities available to the property include natural gas, electricity, telephone, cable, and City sewer and water service. However, Stillwater Auto Parts and Towing uses a septic system which is reported to be malfunctioning. A trench has reportedly been excavated to prevent back-up of sewage into the basement of the building. During the reconnaissance, flow was observed in the trench. An electrical easement, owned by Northern States Power Company extends through the central portion of the property in an east-west direction. Electrical towers, high tension power lines, • and an electrical substation are present within the easement. This Phase I Environmental Site Assessment was performed in conformance with the scope and limitations of the American Society of Testing and Materials Standard Process E 1527-97. This Phase I Environmental Site Assessment has not revealed evidence of recognized environmental conditions (RECs) in connection with the property, except for: REC 1. An area of dead grass off the northeast corner of the electrical substation, indicating a suspected release of herbicide. S.iPROJ10PH1543410PH PHI.WPD 24 • REC 2. Reported release associated with a current or former underground storage tank at the Stillwater Auto Parts and Towing property. Information related to this incident and the cleanup that reportedly occurred could not be located. REC 3. Presence of a large amount of debris and scrap vehicles at the Stillwater Auto Parts and Towing property; staining was also visible in some areas of-the- - property REC 4. Trenched and overland flow of raw sewage at the Stillwater Auto Parts and Towing property due to a malfunctioning septic system. - • • S.PRO OPH MMa►wPH PHI way 25 7.0 RECOMMENDATIONS Based on the findings and conclusions of this Phase I Environmental Site Assessment, Northern Environmental recommends the following: REC 1. A soil and/or water sample should be collected from the area of the dead grass• - and should be analyzed for herbicide contaminants. REC 2. A soil and/or water sample should be collected from the area of the former underground storage tank and should be analyzed to determine if subsurface impacts related to the release incident are present. REC 3. Soil and/or water samples should be collected from multiple areas of the Stillwater Auto Parts'and Towing property, including.heavy debris areas in the southwestern portion of the property,the area near a circular concrete pad,and areas of visible staining. Because the whole property has been utilized as a scrap yard and it is not known where removal of fluids and dismantling of vehicles occurred, borings should be spaced over the entire property. In addition, the large amount of debris observed at the property should be removed and disposed of properly. REC 4. The septic system should be repaired or should be permanently removed from service and properly abandoned in accordance with Minnesota Department of Health regulations. In addition, small piles of debris noted in or near some of the wooded areas of the property during the reconnaissance should be removed and disposed of property. If additional information regarding past site activities or potential off-site sources of contamination becomes available,this information should be reviewed and the need for additional assessment should be re-evaluated. • s:IPROJWPIfi543410PH_PHLWPD 26 8.0 SIGNATURES OF ENVIRONMENTAL PROFESSIONALS The results of this study are based upon the professional interpretation of information available to Northern Environmental during the time and budget constraints of this assessment Northern.. Environmental has considered that the information provided by the cited references is complete and correct Northern Environmental does not warrant that this report represents an exhaustive study - of all possible environmental concerns at the Property. The items investigated as part of this study represent the most likely sources of environmental concern, and are consequently believed to address your needs at this time. �i Staff Environmental Scientist AL.4 r .

CHAPTER 5.0 WELLHEAD/AQUIFER PROTECTION AND PRIVATE WELL MANAGEMENT Issues Statement • Wellhead and Aquifer Protection Wellhead protection(W HP)is the concept of identifying and managing potential contaminant sources within an area contributing water to a public water supply (PWS) well or well field. Wellhead protection is designed to prevent rather than remediate contamination of groundwater. In 1986, the Federal Safe Drinking Water Act was amended to require states to implement wellhead protection programs for public water wells. In response,the Minnesota Ground Water Protection Act of 1989 was created. Under the act, the Minnesota Department of Health (MDH) developed a wellhead protection program In November 1997,Minnesota's Wellhead Protection Rules(MN Rules 4717.700 and 4720.5100 to 4720.5590) were promulgated. These rules set the technical and administrative requirements of the State's Wellhead protection program. The Minnesota Wellhead Protection Program addresses water wells serving the public, including restaurants, public buildings, and municipal water supply systems. Washington County has 28 community and 112 non-community public water supplies. In Washington County,where ground water is the sole source of drinking water,wellhead protection is especially important. Many wellhead protection areas in the county cross local government boundaries. Strong state, county and municipal cooperation will be essential to carry out an effective Wellhead protection program. • Well Management The Minnesota Department of Health licenses well contractors,administers the permitting process for drilling wells and sealing abandoned wells, and inspects new wells in Washington County. Prior to 1974,there was no well construction regulation. Some past pre-well code construction practices,such as construction ofmulti-aquifer wells and failure to grout well casings,resulted in infiltration of surface contaminants into groundwater. Improperly constructed wells act as direct conduits for surface contaminants to enter the ground water. Local geologic conditions may require special well construction methods. For example,the state well code prohibits wells in fractured bedrock within one mile of areas covered by less than fifty (50)feet of glacial drift deposits. The Minnesota Department of Health also regulates well construction in regions of known contamination. These regions are designated Special Well Construction Areas. In a Special Well Construction Area,new wells are required to be completed to more restrictive,specified standards in an effort to avoid tapping into known contaminated aquifers. These efforts are also geared to promote well construction techniques that minimize the risk of cross contaminating aquifers during and after well construction. Abandoned, improperly sealed and poorly constructed wells pose a threat to groundwater quality. Abandoned wells are common in both residential areas developed prior to the availability of a public water supply and in older rural homesteads. Abandoned well identification and sealing efforts should be a high priority, ground water protection strategy. Wellhead/Aquifer Protection and Private Well Management Goals: To protect public water supplies from contamination throughout the county. To assure safe drinking water is provided for human consumption. Wellhead/Aquifer Protection and Private Well Management Policies: 1. Washington County supports the identification of wellhead protection areas and implementation of protective measures based on rules adopted by the Minnesota Department of Health. 2. Washington County recognizes that land use control is the most effective method for wellhead protection. 3. Washington County encourages implementation of best management practices(BMPs)within Wellhead protection areas for existing land uses that are incompatible with the goals of the Wellhead protection program. 4. Washington County encourages Local Governmental Units to address future land use in Wellhead Protection areas. 5. Washington County supports the enforcement and implementation by the Minnesota Department of Health of the Well and Boring Code (MN Stat. 144.00) to prevent contamination of groundwater. 6. Washington County supports identifying and sealing abandoned wells to prevent possible aquifer contamination 7. Washington County supports intergovernmental coordination of a well sealing program to avoid duplication of efforts and increase efficient use of staff and money. Wellhead/Aquifer Protection and Private Well Management Strategies • Washington County will partner with Local Governmental Units to determine groundwater flow properties and assist public water suppliers in delineating well capture zones. • Washington County will ensure land use in Wellhead protection areas in townships are compatible with the goals of the Wellhead Protection program. • Washington County will make available existing inventories,water quality information,and GIS data to public water suppliers and Local Governmental Units developing Wellhead Protection plans. • Washington County will act as a facilitator for interagency cooperation in Wellhead Protection areas that cross jurisdictional boundaries and promote intergovernmental coordination effort • Washington County will provide information to county residents on private well water testing and private water well related education.. • Washington County will promote sealing of unused wells through education and grants,when available. • Washington County will assist Local Governmental Units in conducting abandoned well surveys, especially in Wellhead Protection areas. APPENDIX G OAK PARK HEIGHTS WATER SYSTEM EMERGENCY PREPAREDNESS PLAN 55-01-118 36 Bonestroo,Rosene,Anderlik&Associates,Inc. it Water System Emergency Preparedness Plan Purpose The purpose of this plan is to prepare a detailed description of procedures to follow in the event of a disruption to normal water service. The disruption could be natural or man- made, and could affect the entire water system or only parts of the system. This plan cannot address all potential disasters. It is intended to give the water utility staff a guideline to allow them to quickly restore normal water service with a minimum of disruption, and to minimize any potential health risks. This plan should be coordinated with the emergency plans of other City and regional entities; Police, Fire, Public Works, etc. Emergency Telephone List The Emergency Telephone list is attached. Work and home phone numbers of key emergency contacts and the 24 hour cellular contact are included on Oak Park Heights' phone list, which is not included as a part of this document for data privacy reasons. Also attached is an Emergency Information Reporting form. This form will not cover all emergencies that the City may experience; however, the form will help standardize the reporting/recording process. A standard question format will help staff persons collect accurate and specific information about the emergency so that the proper response can be initiated without delay. Current Water Sources and Service Area Oak Park Heights' DNR appropriation permit number is 75-6123. There are a total of 1049 service connections as of January 1, 1998. Oak Park Heights does not have any surface water sources. Oak Park Heights has two wells connected to the municipal system, both of which are permanent sources. Both wells #1 and #2 are located in the Jordan aquifer. A summary of the well data is included in Table E-1. A map illustrating Appendix E— Water Supply &Distribution Plan E-1 the locations of existing and future wells is shown in the back of the report. A detailed discussion of Oak Park Heights' water sources is found in the "Existing Facilities" section of the Water Supply Description and Evaluation. Procedure For Augmenting Water Supplies The following alternatives exist for additional supplies of water. Interconnect with Adjacent Communities Currently, the City does not share any permanent interconnections with adjacent communities. The following is a list of potential interconnections. • Stillwater at Oakgreen Ave: A 12 inch connection should be made to Stillwater when Highway 36 is reconstructed. Stillwater's water system operates at the same high water level as Oak Park Heights in this area. Therefore, the connection can be very simple— consisting of a valve (normally closed) and a meter to measure flow in both directions. • Stillwater at 65th and 62nd: There are several hydrants in Stillwater east of Osgood near 65th St. and 62nd St. that are in close proximity to hydrants in Oak Park Heights. These hydrant to hydrant connections are being used in the fall of 1998 to provide water to Oak Park Heights north of Highway 36 while the City repairs a leaky water main near Osgood. • Procedure: Connections between Oak Park Heights and Stillwater will be coordinated between Jay Johnson (Oak Park Heights Public Works Director) and Jim McNight (Stillwater Water Board Chair). Jim McNight's phone number is 439-6231. Conjunctive Use of Surface and Ground Waters Although Lake St Croix borders the City, the conjunctive use of surface and ground waters is not a viable option for the City of Oak Park Heights at this time. It is not considered a suitable source of water for water suppliers. It would be extremely costly for Oak Park Heights to build water treatment plants with the necessary equipment to treat surface water to potable standards. Appendix E— Water Supply &Distribution Plan E-2 Alternative Sources of Water The City of Oak Park Heights utilizes the Jordan aquifer. Other possibilities for water supply provisions during extended emergency periods would be to either bring potable water in via trucks, or investigate the possibility of purchasing water from neighboring communities. Demand Reduction Procedures Demand reduction procedures should be initiated during unusually high demand periods or shortage of water due to an emergency. The restrictions should relate to the severity of the emergency or shortage. Demand Reduction Potential Oak Park Heights' usage during the summer months is higher than during the winter months. In the future it is important that the city keep track of daily pumpage to improve evaluation of demand reduction potential. For demand/supply emergencies during the summer months, sprinkling bans can easily be instituted for all of the customer categories. These sprinkling bans would have the potential for significant short-term demand reduction. The City should initiate discussions with the Minnesota Correctional Facility to determine short-term demand reduction potential at that facility. Short-Term Demand Reduction Procedures The following short-term demand reduction measures are a current part of Oak Park Heights' conservation plan. The measures are progressively more stringent for use as the length or severeness of the emergency warrants. Triggers for each of these measures are outlined in the following sections. 1. Voluntary Reduction Measures: Public service announcements, door-to-door notices, direct mailing, community bulletin boards, Cable T.V. and notices in the local paper. 2. Sprinkling Bans: The City currently has a water policy that authorizes the City Administrator to issue restrictions on lawn sprinkling at anytime (copy attached). Appendix E— Water Supply &Distribution Plan E-3 3. Water Allocation Restrictions: Based on severity of emergency and water use priorities established in next section. Procedures for Water Allocation Initial emergency response will include actions to augment supplies and/or reduce demands. However, severe water shortages may require the City of Oak Park Heights to allocate water based on the following priorities. These priorities are established by Minnesota Statutes 103G.261. Non-essential uses of water are the lowest use priority and will be the first water use subject to allocation restrictions. Quick responses to restrict non-essential uses of water during periods of limited supplies will help protect domestic and economic uses of water. Therefore, the City of Oak Park Heights will be quick to step in and limit the non- essential use of water. First Priority. Domestic water supply, excluding industrial and commercial use of municipal water supply, and use for power production (which currently does not apply to Oak Park Heights) that meets contingency requirements. Notify all customers Second Priority. Water uses involving consumption of less than 10,000 gallons per day. Notify all commercial/industrial customers Third Priority. Agricultural irrigation and processing of agricultural products. Does not apply to Oak Park Heights Fourth Priority. Power production in excess of the use provided for in the contingency plan under first priority. Does not apply to Oak Park Heights Fifth Priority. Uses, other than agricultural irrigation, processing of agricultural products, and power production. Does not apply to Oak Park Heights Appendix E— Water Supply &Distribution Plan E-4 Sixth Priority. Non-essential uses. These uses are defined by Minnesota Statutes 103G.291 as lawn sprinkling, vehicle washing, golf course and park irrigation, and other non-essential uses. Notify all customers While initial emergency responses may include actions to augment supplies and/or reduce demands, severe water shortages would require water allocation in accordance with these priorities. Triggers for Implementing Plan Components The critical factor in the Oak Park Heights water system is the well pump supply. The following triggers are initiated based on the percentage of well capacity. The triggers will be updated when future wells are added. Trigger Measure % of Well Capacity MGD(1) Firm Capacity: 1.15 Voluntary Reduction Measures Always Always Odd/Even Sprinkling Ban 85 0.98 Total Sprinkling Ban 90 1.04 Eliminate 6th Priority Allocation 95 1.09 Eliminate 2nd Priority Allocation 100 1.15 (1)Firm capacity is the capacity of the wells with the largest well out of service. Appendix E— Water Supply &Distribution Plan E-5 Enforcement The City has a water policy that gives the City Administrator, in consultation with the Publics Works Director, authorization to issue restrictions on lawn sprinkling. Such restrictions may include an odd/even sprinkling ban or limitations on the hours of the day or the days of the week during which lawn sprinkling is prohibited. In addition, the Administrator may declare a total sprinkling ban if needed. The focus of Oak Park Heights' short-term demand reduction plan is on voluntary reduction of non-essential uses of water. The City mails notification of the possibility of sprinkling bans with the spring bills. In this mailing the City informs customers that notification of the sprinkling bans will be made in the City's two local papers, the Gazette, and the Courier. Enforcement will become more stringent as the emergency progresses. Odd/even sprinkling bans will be monitored and enforced by the public works department and the Oak Park Heights Police. Failure to comply with water use restrictions may be subject to a misdemeanor. Water Supply Protection Analysis of Previous Supply Problems No major repairs have been necessary and only a few minor water main breaks have occurred. The City will be monitoring the original section of distribution piping more closely as the system ages. All tools necessary for repairs of water lines and pump house equipment are on hand at all times. The City also has access to pipes, valves and tools from a local supplier at all hours. As the system ages and repairs become more necessary the City will need to increase the supply of piping as well as valves, couplings, etc. to reduce repair time. Wellhead Protection Water supply protection is an essential part of the Oak Park Heights water plan. The City has started the wellhead protection planning process. The first phase of planning was Appendix E— Water Supply &Distribution Plan E-6 completed in February, 1998 with a report by Northern Environmental entitled, Wellhead Protection Area And Drinking Water Supply Management Area Delineations, And Aquifer And Well Vulnerability Assessments. Resource Monitoring The City periodically measures the static water levels and pumping levels in their well and will continue to do so in the future. This information will be used to detect significant changes in aquifer conditions. In addition, MDH performs annual water quality testing at each of the wells in accordance with the provisions of the Clean Water Act. Examples of previous water quality lab results are included in Table E-1 of this plan. Emergency Resources A good maintenance program can identify potential problems before they become an emergency. The City's water system is in excellent condition, due to a proactive maintenance program. The following are the major components of Oak Park Heights maintenance program, and recommendations for future improvements. Valves: Valves are checked occasionally as personnel are available. The City needs sufficient personnel on call during valve turning operations in case a valve breaks or a leak develops. Recommendations: Establish a schedule for valve turning, maintain better records on valve maintenance, and have sufficient personnel available to repair any problems that arise during valve exercising. Begin to organize valve data for the City's Geographic Information System(GIS). Test all pressure reducing valves at least twice a year. Hydrants: Every hydrant is checked once a year. Hydrants are also checked in the winter to make sure they are dry. Their Fire Department is working with the Utility to accurately map all hydrants. Recommendations: Include hydrant data in the City GIS. Appendix E— Water Supply &Distribution Plan E-7 Breaks/Repairs: The City maintains records of all breaks and repairs. Prior to any street reconstruction project, the break record is reviewed to determine if pipe should be replaced. The City has an inventory of repair parts, valves, and sleeves at the Public Works Department. Recommendations: Include break locations on the City GIS. Power The City currently has purchased emergency backup power. The trailer mounted generator is kept at City Hall. In the event of a power failure the generator will automatically run for Well 1. Recommendation: Establish a plan for utilizing emergency generators. Labor Oak Park Heights has an emergency contractors list, which specifies a variety of contractors who have agreed to perform emergency services. The list has been included in this plan. Control System The computerized control systems for water treatment and distribution are indispensable to water supply operations. In case of an emergency, a municipality must have a well- planned control system. Following are a number of alternatives to be considered for preventing failure of a computerized control system: 1. Routine maintenance programs. 2. Backup power sources. Communications Systems Communication systems are vital to water supply operations. Unfortunately, communication lines, such as telephone lines, are susceptible to many types of disasters Appendix E— Water Supply &Distribution Plan E-8 (storms, construction accidents, etc.). Accordingly, it is important that backup communication systems be maintained and tested regularly. The City of Oak Park Heights alarms are sent to the same location as the City's Police Department. Police department has personnel at this building 24 hours a day. In the event of an emergency, the police department will contact the appropriate City Personnel. Sensors Water system sensors and detectors are important for recognizing and correcting emergency situations. Pressure transducers and limit switches should be checked and calibrated regularly. Security The safety of a water supply and distribution system is critical to any community, and acts of vandalism or terrorism should never be allowed to compromise this valuable resource. A security system including the use of electronic keys or some similar device could be implemented to control access to water system facilities. Currently all entrances to facilities are kept locked. Keys to entrances are provided only to operators/maintenance personnel. Operation and Maintenance Manuals Operation and maintenance manuals are conveniently located throughout system facilities so as to provide the public works staff with accessible instructions in case of an emergency. Replacement Parts An adequate supply of replacement parts are stored at the water utility facilities as recommended by the manufacturers of the equipment in case of an emergency. Appendix E— Water Supply &Distribution Plan E-9 Emergency Response Procedures Water Quality Water quality problems occur due to difficulties that can not be managed by the normal treatment process of the system. Difficulties that might be encountered include source contamination, a stoppage of treatment, or contamination of the distribution system. An extensive monitoring program will enable operators to detect contamination in the distribution system. Unfortunately, it takes as long as several days for the necessary data to be generated in a laboratory. When the origin of the water contamination is unknown, each phase of the water supply system should be inspected for possible problems. When there is reason to believe that the water supply has been contaminated, customers and health authorities will be contacted without delay. Informing the customers of the emergency is especially important, as they should be instructed regarding the appropriate precautions to take. Recommendation: Update the chlorination equipment in the pump houses so that it is available in an emergency.

Appendix E— Water Supply &Distribution Plan E-11 Storms The effect of storms on water facilities are typically fires, flooding, power outage or lightning damage to equipment. Structural damage to towers and buildings may also occur depending upon the type of storm. In the event of a power outage, storm damage or lightning damage to equipment, the City will: 1. Determine if emergency generator and Well 1 are operating. 2. Determine available storage volume. 3. Contact Northern States Power Company and get an estimated time for.power restoration. 4. Assess damage to controls and sensing equipment. Depending on the outcome of steps one and two, Oak Park Heights will take the following measures: • obtain an alternative emergency power source • notify fire department • operate system manually if necessary Droughts Monitoring of the weather can enable one to predict the possibility of a drought occurring. During drought periods, tower and well levels will be monitored daily. The monitored information will be used to help determine whether any triggers have been reached. Furthermore, it is necessary to have emergency plans for limiting water consumption that can be implemented without delay. Personnel In any emergency, it is necessary for the utilities staff to know their respective duties in resolving the crisis. At the City, all certified water utility operators are trained in emergency procedures. In addition, it is the City's policy that all operators should attend continuing education on emergency procedures. In the future, an emergency duty Appendix E— Water Supply &Distribution Plan E-12 description manual may be developed to clearly communicate specific emergency procedures to the employees.
