ISSUE In accordance with Minnesota Administrative Rules,Chapter 4720,Public Water Supplies,municipal water suppliers are required to maintain a Wellhead Protection Plan for municipal water wells. The City's initial Wellhead Protection Plan,Parts 1 and 2 were completed in 2002 and 2003,respectively. In accordance with state rules,an update of these documents is required every 10 years. The Wellhead Protection Plan, Part 1 update was approved by the Minnesota Department of Health in April 2010. At this time, the Final Draft Wellhead Protection Plan, Part 2 update is complete and being presented to Council for adoption. BACKGROUND The Wellhead Protection Plan,Part 1 included the development of wellhead protection areas for each of the city's eight municipal supply wells along with the delineation of a drinking water supply management area (DWSMA) for the city. Also included in Part 1 was the completion of a vulnerability assessment for the groundwater aquifers within the DWSMA. Part 2 of the Wellhead Protection Plan includes the following: • Review of data elements identified by the Minnesota Department of Health as applicable to the DWSMA. • Results of an inventory of potential contaminant sources within the DWSMA. • Review of changes,issues,problems, and opportunities related to the public water supply and the identified potential contaminant sources. • A discussion of potential contaminant source management strategies and the goals, objectives,and action plans associated with these management strategies. • A review of the wellhead and source water protection evaluation program and the city's alternative water supply contingency strategy. A public hearing is required prior to city approval of the plan update.

Part 2 of the Plan was completed in October of 2003 and approved by the Minnesota Department. The Wellhead Protection Plan (Part 1 and Part 2)presented the delineation of the Wellhead Protection Areas(WHPA)and the drinking water supply management area (DWSMA)and the vulnerability assessments for the system's wells and aquifers within the DWSMA.The boundaries of the WHPA/DWSMA as shown in the 2003 Part 2 Plan have since expanded and are shown in Figure 1,Appendix B.Portions of the WHPA/DWSMA extend into a portion of Empire Township,the City of Lakeville,and the City of Apple Valley.Water supply wells covered by this delineation and this Part 2 Plan Update are listed on page 5 and in Chapter 1. The vulnerability assessment for the aquifers within the DWSMA was performed using available information and indicates that the vulnerability of the aquifers used by the system varies from high to low.The results of the aquifer vulnerability assessment determine what types of potential contamination sources must be managed within the DWSMA: • Low vulnerability areas-wells • Moderate vulnerability areas-wells and tanks • High vulnerability areas-all land uses and potential contaminant sources This document updates those portions documented in Part 2 and includes the following information: • A review of data elements identified by the Minnesota Department of Health as applicable to the DWSMA. • Results of an inventory of potential contaminant sources within the DWSMA. • Review of changes,issues,problems,and opportunities related to the public water supply and the identified potential contaminant sources. • A discussion of potential contaminant source management strategies and the goals, objectives,and action plans associated with these management strategies. • A review of the wellhead and source water protection evaluation program and Rosemount's alternative water supply contingency strategy. The goals and objectives of this Plan focus on managing potential contaminant sources within the DWSMA,reducing the potential contaminant pathways to the source water aquifer that may be provided by private wells,educating property owners and water supply users,and working with Empire Township,the City of Lakeville,and the City of Apple Valley to ensure proper management of the portion of the DWSMA in their respective community. City of Rosemount,MN WSB Project NO. 1582-06 7 f P a g e Wellhead Protection Plan-Part 2 Draft October 2012 The City of Rosemount's WHP team has identified the following goals for implementation of this Plan: GOAL 1:The City will work to maintain or improve the current level of water quality so that the municipal water supply will continue to meet or exceed all applicable state and federal water quality standards. GOAL 2:The City will work to continue to supply sufficient water quantity for system users and emergency needs. GOAL 3:The City will provide and promote activities that protect the source water aquifer that provides water to the municipal system.This will include increased public awareness of the Wellhead and Source Water Protection Program and groundwater-related issues,and management of the identified potential contaminant sources and conveyance mechanisms within the DWSMA. GOAL 4:The City will continue to collect data to support future wellhead and source water protection efforts. Implementation of these goals will be achieved through direct management efforts to the following areas to prevent future contamination of the aquifer and increase awareness of groundwater protection: A. Well Management B. Public Education C. Storage Tank Management D. Septic Systems (ISTS) E. Stormwater Management F. Potential Contaminant Source Management G. Hazardous Waste Management H. Data Collection I. Water Conservation J. Planning and Zoning K. Evaluation The success of the Wellhead Protection Plan must be evaluated in order to determine whether or not the Plan is accomplishing what the City of Rosemount intended to do.Monitoring and evaluation of the Wellhead Protection Plan and associated activities will be conducted every two and a half years that the Plan is in effect. City of Rosemount,MN WSB Project NO. 1582-06 8 ! Page Wellhead Protection Plan-Part 2 Draft October 2012 CHAPTER ONE DATA ELEMENTS AND ASSESSMENT (4720.5200) Rosemount currently uses the following wells to provide the City's drinking water: • Well 7-unique number 112212 • Well 8-unique number 509060 • Well 9-unique number 554248 • Well 12-unique number 706804 • Well 14-unique number 722623 • Well 15-unique number 753663 • Well RR-1-unique number 457167 • Well RR-2-unique number 474335 The DWSMA delineated in the Wellhead Protection Plan area delineation study extend into a portion of Empire Township,the City of Lakeville and the City of Apple Valley.The DWSMA is found in Township 114,Range 19,Sections 4,5,6,7,8,Township 115,Range 19,Sections 16,20,21,22, 26,27,28,29,30,31,32,33, 34,Township 115,Range 20,Sections 25,36,and Township 114, Range 20,Section 1. L REQUIRED DATA ELEMENTS A. PHYSICAL ENVIRONMENT DATA ELEMENTS In accordance with Minnesota Rules Chapter 4720.5200,the data elements and their assessments required to be included in the Wellhead Protection Plan for the City of Rosemount are presented in this Section.Data elements discussed in this Section include precipitation, geology and hydrogeology,soils,and water resources. 1. Precipitation Rosemount's municipal wells and the source water aquifer within the DWSMA are classified as vulnerable to contamination,and as such precipitation must be evaluated to determine if it could potentially apply to the Plan. As shown on Figure 14,Appendix B,there are three National Weather Service(NWS) precipitation gauging stations in Dakota County.These stations are located in Farmington, Hastings,and at the University of Minnesota Rosemount Agricultural Experiment Station.In addition,there are a number of other precipitation gauging stations in Dakota County whose locations are not shown on the map.Locations of the NWS stations and the additional gauging stations are identified by township,range,and section in Table 2, Appendix A. City of Rosemount,MN WSB Project NO.1582-06 9 I P a g e Wellhead Protection Plan-Part 2 Draft October 2012 As outlined in the Part 1 Plan,and reiterated in the 2003 Part 2 Plan,the Jordan Sandstone aquifer is under leaky-confined hydrogeologic conditions in and around Rosemount and considered vulnerable because of the presence of tritium in some wells. This combined with the vulnerability of the DWSMA ranging from low to high,it is important to consider precipitation in relation to management of land use in the DWSMA because it can act as a transportation mechanism by infiltration or runoff.A contaminant maybe displaced through the soil medium in the direction of the source water aquifer,through the municipal storm sewer system,or across impermeable surface features during rain events. 2. Geology The regional groundwater flow system is composed of three aquifers:the glacial drift/St.Peter Sandstone,the Prairie du Chien Group,and the Jordan Sandstone.The City of Rosemount municipal wells are all completed in the Jordan Sandstone aquifer. The surficial geologic unit in the vicinity of the DWSMA consists of unconsolidated glacial drift deposits including sand,gravel,and clay.Based on the well logs for the Rosemount municipal wells,these unconsolidated deposits are approximately 90 to 180 feet thick within the DWSMA. The uppermost bedrock unit within the DWSMA varies with location and includes the Platteville Limestone,Glenwood Shale,St.Peter Sandstone,and the Prairie du Chien,as shown in Figure 2,Appendix B.Well logs for the Rosemount municipal wells indicate that,where present,the St.Peter Sandstone is approximately 30 to 40 feet thick The Prairie du Chien dolomite in the area of the DWSMA is approximately 200 feet thick As a result,the top of the Jordan Sandstone is more than 320 feet below the ground surface within the DWSMA. The water table in the Rosemount area is generally present in the drift deposits.Where it is not in the glacial drift,the water table is in the St.Peter Sandstone.As noted above, the groundwater flow system is divided into three aquifers.Hydraulic interaction with the deeper regional aquifers beneath the Jordan Sandstone is considered negligible. Between each aquifer unit in the study area is a leaky aquitard.Between the glacial drift/St.Peter Sandstone aquifer and the underlying Prairie du Chien Group,the aquitard consists of the basal portion of the St.Peter Sandstone(a shaley unit approximately 5 to 15 feet thick) and glacial till. Between the Prairie du Chien Group and the Jordan Sandstone,a resisting aquitard layer is present that combines the leakage resistance effects of vertical anisotrophy of hydraulic conductivity and lower hydraulic conductivity conditions in the basal portion of the Oneota Formation (the basal member of the Prairie du Chien Group).As a result,the Oneaota Formation separates the Prairie du Chien Group aquifer from the underlying Jordan Sandstone aquifer.This interpretation is supported by Part 1 analysis that are consistent with the Jordan Sandstone being under leaky-confined conditions.While it addresses the Prairie du Chien Group and the Jordan Sandstone as a single aquifer,the Dakota County City of Rosemount,MN WSB Project NO. 1582-06 10 page Wellhead Protection Plan- Part 2 Draft October 2012 Geologic Atlas also indicates that the Prairie du Chien-Jordan aquifer is under confined conditions under most of Rosemount,including in the vicinity of the DWSMA. Infiltrating precipitation and leakage from lakes and rivers,which tend to be perched above the water table,recharge the glacial drift/St.Peter Sandstone aquifer in Dakota County.The primary source of water for the bedrock aquifers(i.e.the Prairie du Chien and the Jordan Sandstone) is leakage from adjoining aquifer units.The Dakota County, groundwater discharge is to the major streams;the Minnesota River,the Mississippi River,the Vermillion River,and the Cannon River. Groundwater flow in the vicinity of the Rosemount DWSMA is generally northeasterly in all aquifer units. 3. Soil Conditions Surficial soil types within the DWSMA are shown on Figure 3,Appendix B. Since the Rosemount municipal wells and source water aquifer within the DWSMA are classified as vulnerable,surficial soil characteristics must be evaluated to determine if they could potentially apply to the plan.While there are known erodable lands within the DWSMA (Figure 5,Appendix B),they are not currently causing sedimentation problems. Based on the aquifer vulnerability assessment results,issues related to surficial soil characteristics or the surficial soil types may have an effect on the management strategies developed for the DWSMA.Surficial geologic materials in the City of Rosemount consist of sand,gravel,and porous soils. (Figure 4,Appendix B).City staff is well aware that all types of land development and land use activity may have an impact on the source water aquifer due to surface water infiltration through the permeable soil types in the City of Rosemount DWSMA. 4. Water Resources Surface water resources must be evaluated to determine if they could potentially apply to the Plan,since the Rosemount municipal wells and source water aquifer within the DWSMA are classified as"vulnerable". Based on the aquifer vulnerability assessment results,issues related to surface water resources may impact the quality of the groundwater reaching the City's wells.Due to the geologic conditions in and around the City's DWSMA and the vulnerability of the aquifer to contamination,surface water management is critical for maintaining a water supply of high quality.The quality of the source water is dependent on the quality of its recharge.Recharge sources/mechanisms are noted above.Surface water management will be conducted so as to reduce the potential negative effects that surface waters may have on the source water aquifer.Management strategies in this Plan will address current and future surface water quality in the area so that aquifer recharge and water availability does not become an issue for the City. City of Rosemount,MN WSB Project NO. 1582-06 11 Page Wellhead Protection Plan-Part 2 Draft October 2012 B. LAND USE DATA ELEMENTS Current and historic land use in the vicinity of the DWSMA is discussed in this section. Parcel information for the City of Rosemount, Empire Township,City of Apple Valley,and City of Lakeville were used to delineate the DWSMA(see Appendix B). 1. Land Uses a. Current Land Use It is important to understand land use in order to determine key areas for concern in managing a wellhead protection area.For example,knowledge about the location of future development or areas of redevelopment within the DWSMA may reveal a need to closely manage the activity within more sensitive areas.Additionally,any land uses that currently pose a potential threat to the City's water supply would need to be highlighted to increase awareness of any concerns.Since the Rosemount municipal wells and the source water aquifer within the DWSMA are classified as vulnerable,current land use must be evaluated to determine if it could potentially apply to the Plan. Figure 6,Appendix B shows the DWSMA superimposed over the existing land use maps for those communities within the DWSMA from their Comprehensive Plans. Land uses found within the DWSMA include agricultural,single family residential, multi-family residential,commercial,office,industrial,institutional, parks/recreational and open space,and gravel mining.Information for this section was taken from the City of Rosemount's Comprehensive Plan(2009),Empire Township's Comprehensive Plan(2009),City of Apple Valley's Comprehensive Guide Plan(2010),and City of Lakeville's Comprehensive Plan(2008). Potential threats to the water supply were determined by analyzing data relevant to the public water supply wells,the quality of water being drawn into the wells,or land and groundwater uses around the wells.MDH provided a list of potential contaminant sources extracted from state and federal databases on above ground and underground storage tanks,leaking underground storage tanks,state permanent list of priorities sites,voluntary investigative cleanup sites,agricultural chemical storage sites,hazardous waste generators,etc.Listed sites within the DWSMAs were identified and mapped(see Figure 9,Appendix B).Results of this inventory indicate the presence of several potential contaminant sources within the DWSMA.These potential sources include various commercial,medical,dental, mineral extraction,disposal,institutional,industrial,and storage tank sites.A summary of the results is presented in Table 1,Appendix A. Possible contaminant sources were identified and evaluated within the DWSMA.It is important to realize that the WHPA does cover multiple municipalities,so cooperation between Rosemount and the neighboring Township and Cities is City of Rosemount,MN WSB Project NO. 1582-06 12 [ P a g e Wellhead Protection Plan- Part 2 Draft October 2012 essential.The following potential contaminant sources were found to be within the DWSMA: • Public and Private Wells. Figure 10,Appendix B shows a map that includes all public and private wells that were located. 46 wells, 12 of them for public supply,are located within the DWSMA. There may be more wells that were not located. All of these wells are either active or sealed,with some exceptions. The exceptions include two"Scientific Investigation"use wells,and four public wells that are considered"unknown"or"abandoned"but do not have sealing records. There are no known shallow disposal wells in the DWSMA • ISTS. Shallow groundwater is highly susceptible to pollution from septic tanks. There are 22 parcels in the DWSMA with septic systems,as determined by the absence of sanitary sewer connections for parcels with structures. The septic systems are shown in Figure 12,Appendix B. • Spill Sites. There are multiple areas of known contamination within or near the DWSMA-the Gopher Ordinance/UMore Park sites and the Flint Hills refinery to the northeast of the DWSMA are the two largest. These and others are potential contaminant sites and are currently being monitored by the MPCA. • Storage Tanks. Documented storage tanks within the DWSMA include multiple fuel stations,both automotive and pipeline related,and farms. The rest of the documented storage tanks in the DWSMA are for heating oil and industrial chemicals. These are all shown on Figure 9,Appendix B. • Other, There are numerous sites within the DWSMA that are included in the PCSI,including dumps and leaking underground tanks that have been removed, Hazardous Waste Generators such as dental offices,x-ray machines,film development chemicals,solvent tanks,dry cleaners,paint storage and application,a funeral home,and a decommissioned wastewater treatment facility that should all be monitored as potential contaminant sources. b. Historical Land Use The historical land use analysis conducted for the 2003 Well Head Protection Plan was updated to determine if historical land use could potentially apply to the Plan. A review of available information on historic land use in the City of Rosemount, Empire Township,City of Apple Valley,and the City of Lakeville was conducted. Research was conducted based on aerial photography,historic land use maps and utility as-built drawings.Field investigations were performed in designated areas where no information was available. Land activity was reviewed for potential influence on water quality in the DWSMA. Similar to the 2003 analysis,the information available did not indicate any land use or land activity that would potentially create a significant impact within the City of Rosemount,MN WSB Project NO. 1582-06 13 I P a g e Wellhead Protection Plan-Part 2 Draft October 2012 DWSMA.Agriculture was determined to be the primary land us/land activity in the area.There have been no properties within the DWSMA that have presented a threat to the source water aquifer within the DWSMA based on a previous land use activity. Empire Township has indicated that,prior to the start of sand and gravel mining in the portions of the Township within the DWSMA,the land use in this area had been agricultural and no other prior land uses are known. 2. Public Utilities Since portions of Rosemount's DWSMA are classified as vulnerable,public utilities were evaluated to determine their potential influence and impact on Rosemount's drinking water supply.Public utilities located within the DWSMA include water,sanitary sewer and stormwater piping,as shown in Figures 10, 11,and 12,Appendix B.The public utilities in the DWSMA should not create a significant risk to groundwater quality because of their relatively shallow depth or encasement in pipe,since Part 1 of the City's WHPP did not show a hydraulic connection between surface waters and the City's aquifers. Empire Township is largely utility-free,with most properties having their own well and individual sanitary treatment system(septic system). C. WATER QUANTITY DATA ELEMENTS Water levels in lakes and streams can have an impact on an aquifer that is unconfined if there is a connection between the surface water system and the aquifer system.Part 1 of the Wellhead Protection Plan did not identify any hydraulic connection between surface water and the aquifer systems in Rosemount's DWSMA.However,high capacity wells in the same aquifer can influence the hydraulics of the aquifer if the pumping rate and volume is large enough. 1. Surface Water Quantity Surface water bodies did not influence the delineation of the wellhead protection areas, but were still included in the model. A conjunctive delineation was not required to be included in the model and was not performed. 2. Ground Water Quantity Fixed radius capture zones were also calculated for five nearby high capacity wells(see Part 1) in addition to the eight municipal wells. For these additional high capacity wells the average pumping rates from 2003-2007 were used. Projections of future pumping rates were determined only for the Rosemount municipal wells. The capture zones of these wells did not intersect the capture zones of the Rosemount municipal wells and were,therefore,not considered in the analysis. City of Rosemount,MN WSB Project NO. 1582-06 14 page Wellhead Protection Plan- Part 2 Draft October 2012 D. WATER QUALITY DATA ELEMENTS Water quality is an indication of aquifer vulnerability. 1. Surface Water Quality Since surface water in the vicinity of the City is not in direct hydraulic connection with the City's aquifers,surface water quality was not reviewed. 2. Ground Water Quality Groundwater bacteriological and chemical data have been reviewed as part of Part 1 of the Wellhead Protection Plan. II. ASSESSMENT OF DATA ELEMENTS A. USE OF MUNICIPAL WELLS The City of Rosemount currently operates(8)active water supply wells (Wells No.7,8,9, 12,14,15,RR1 and RR2),located in and around the City(see Figure 1,Appendix B). Additional information about Rosemount's water supply system in general is presented in the City's 2030 Comprehensive Guide Plan-Water Supply Plan.In addition,well construction details,well logs,and past and projected pumping rates are included in the Wellhead Protection Plan Part 1 document. B. WELLHEAD PROTECTION AREA DELINEATION CRITERIA See the Part 1 Plan for documentation regarding how the following delineation criteria were applied to determining the boundaries of the WHPA: 1. Time of Travel- 10 years 2. Aquifer Transmissivity-geologic information,MPCA Metro Model,Metropolitan Council's Metromodel 2.0 3. Daily Volume of Water Pumped-historical volumes and projected future volumes, which ever was greater. 4. Hydrologic Boundaries- Major groundwater flow boundaries in the area consist of the Minnesota River to the northwest,the Mississippi River to the northeast,and the Vermillion River to the south.For groundwater flow modeling,the boundaries consisted of the Minnesota and Mississippi Rivers,a constant head boundary south of the Vermillion River,and a specified flux boundary to the west. S. Groundwater Flow Field-MODFLOW C. QUALITY AND QUANTITY OF WATER SUPPLYING THE PUBLIC WATER SUPPLY WELL Rosemount continue to have excellent drinking water quality that is free of pathogens and disease causing organisms and meets or exceeds state and federal water quality requirements.Water samples have been regularly obtained from the City wells and tested for regulated contaminants.As mentioned in Part 1,data summaries were obtained from City of Rosemount,MN WSB Project NO. 1582-06 15 page Wellhead Protection Plan- Part 2 Draft October 2012 the Minnesota Department of Health,and it was determined based on this data that tritium was detected in City Wells No.R1, 7,8,and 9.Tritium is not a health hazard,but is an indicator of vertical migration travel time and aquifer vulnerability.The presence of tritium indicates that some portion of the water entered the aquifer(s)after 1953. Levels of nitrate have been below detection/accuracy limit and have not been identified as a concern by MDH No volatile organic compounds(VOCs)were detected. Pumping records submitted to the Minnesota Department of Natural Resources as identified in Part 1 were used to identify the extraction rates of the City wells.These data, along with the past and projected pumping rates,are presented in Part 1. D. LAND AND GROUNDWATER USES IN THE DRINKING WATER SUPPLY MANAGEMENT AREA (DWSMA) The DWSMA associated with Rosemount municipal wells has been determined to be vulnerable,ranging from low to high vulnerability. Land uses within the DWSMA could affect source water protection efforts or the management of the DWSMA. A summary of potential contaminant sources identified in the DWSMA was provided in Table 1, Appendix A.Proactive management of existing wells,unsealed or used wells are of immediate concern within the vulnerable portions of the DWSMA.Management strategies must also be developed for hazardous waste generators,public utilities infrastructure and non-point sources of contamination in the highly vulnerable portions of the DWSMA. Specific non-point source land use acreage was not determined for this report,but the land use and zoning maps(see Figure 5 and 6,Appendix B)provide a tool for understanding the scope of land uses in the DWSMA.Furthermore,the inventory was made as complete as practicable at the time of the development of this Plan.Additional land use discussion is included in Part Three.Plan goals,objectives,and actions are included in Part Four and Part Five. Management strategies are discussed in Part Five,which focus on activities that have the most potential to impact the aquifer system the City of Rosemount is using for its drinking water supply.Despite the vulnerable designation of a majority of the DWSMA,non-point sources of contamination are of less immediate concern than are larger potential point sources,particularly those in high vulnerability areas. Privately owned wells,particularly those that are completed in or penetrate the Jordan aquifer,will continue to be considered when developing the management strategies for the Rosemount DWSMA. Unmaintained,damaged,poorly constructed,or unused/abandoned wells could provide a direct route for contaminants to enter the Jordan aquifer. Potential contaminant sources within the DWSMA identified through the PCSI include storage tank sites,chemical storage sites,hazardous waste generators,dumps,residential land uses,transportation corridors,and gravel pits.These land uses/facilities will be considered when developing the management strategies for the Rosemount DWSMA. City of Rosemount,MN WSB Project NO. 1582-06 16 Page Wellhead Protection Plan-Part 2 Draft October 2012 As previously noted,there are some non-municipal wells that extend into the Jordan aquifer within the DWSMA.These wells could provide pathways for contaminants to reach the Jordan aquifer.Such wells will be addressed by the management strategies developed for the DWSMA. City of Rosemount,MN WSB Project NO.1582-06 17 ( P a g e Wellhead Protection Plan-Part 2 Draft October 2012 CHAPTER TWO IMPACT OF CHANGES ON PUBLIC WATER SUPPLY WELLS(4720.5220) In accordance with Minnesota Rules 4720.5220 a wellhead protection plan must identify and describe expected changes that may occur during the next ten years to: 1. The physical environment 2. Land use 3. Surface water 4. Groundwater L POTENTIAL CHANGES IDENTIFIED A. PHYSICAL ENVIRONMENT Currently,changes in the physical environment,the municipal wells or corresponding DWSMAs are anticipated in the next 10 years or the life of this Plan. Gravel pits currently in the DWSMA may expand or new gravel mining operations may become active on properties within the DWSMA in the next 10 years. In May 2012 the City approved an Ordinance to permit large scale mineral extraction as an interim use in the AG;Agricultural zoning district.In June 2012 an application was submitted for a large scale mining extraction permit.The proposed mining activity extends into the southeast corner of the DWSMA in low,moderate and high vulnerable areas. The City of Rosemount will work with the Township Board of Supervisors to manage the portion of the DWSMA within the Township. The extraction efforts on behalf of the mining operation in Empire Township,within the DWSMA,may influence the surface to water table aquifer interaction over the course of the operation.As described in Chapter 1,the water table occurs in geologic units that are stratigraphically above the source water aquifer. However,it is potentially possible that any contaminants that would reach the water table as a result of the mining operation could eventually migrate to the source water aquifer. Changes to the physical environment resulting from gravel mining operations are unlikely to affect the aquifer vulnerability significantly since the vulnerability is already classified as "high"because of the presence of tritium in the City wells.However,where processing of concrete and asphalt will occur,the DWSMA is classified as"low"to"moderate".Therefore, changes to the physical environment will likely not affect the management strategies for the Rosemount DWSMA presented in this Plan unless research and/or monitoring reveals that existing City wells are impacted by planned mining operations. City of Rosemount,MN WSB Project NO. 1582-06 18 page Wellhead Protection Plan-Part 2 Draft October 2012 B. LAND USE Many of the properties within the DWSMA are developed.A land use map for the year 2008 and a future land use map for the year 2030 are shown on Figures 6,Appendix B and Figure 11,Appendix B,respectively.Projected land uses are used to be consistent with Empire Township,the City of Apple Valley,and the City of Lakeville's current growth planning.Comparison of the year 2008 and the future land use for the year 2030 indicates that,in general,undeveloped properties within the DWSMA will be developed.Future uses of these properties will include residential,commercial,public/institutional,park and open space and potential gravel mining areas. Future land use proposed for the year 2030 includes agricultural,residential(low,medium, and high),office,commercial,light industrial,institutional,parks and open spaces,and potential gravel mining.All of these future land uses are currently present within the DWSMA,thus no new land uses not currently present within the DWSMA are anticipated during the next 10 years of the life of this Plan. C. SURFACE WATER Part 1 of the Wellhead Protection Plan determined that surface water did not significantly contribute to Rosemount's water supply. However,surface water that infiltrates into the groundwater system has the potential to enter the water supply if the strata isolating aquifers from the water table leak(which may be the case where fractured carbonate rock is first bedrock). Recent changes in stormwater management have placed an emphasis in local infiltration of stormwater in order to improve surface water quality. It is yet unclear as to how local stormwater infiltration will affect the quality and quantity of the recharge water, By infiltrating stormwater on site it may improve groundwater quantity,since less water will be conveyed out of the recharge areas. However,contaminants may also be infiltrated along with the water. The long term effects of infiltration should be monitored. Proposed aggregate mining will create a mine pit lake due to mining below the water table and stormwater management and reclamation plans in and around the DWSMA will include the construction of permanent stormwater ponds. These activities may potentially impact groundwater in the Jordan if the water table and the Prairie du Chien aquifers are more hydraulically connected to their source aquifer than currently thought. Rosemount is taking an active approach to mitigating risks that mining and reclamation may impose to the water supply. This includes requirements such as approval of a groundwater monitoring plan and spill and emergency response plans specific to mining operations. D. GROUNDWATER The metropolitan Council and the Minnesota DNR have determined that water level in the Metro area groundwater systems have been gradually falling over the last few decades. Falling water levels in the aquifer used to source Rosemount's water supply will result in higher energy use or lower pumping rates over time. City of Rosemount,MN WSB Project NO. 1582-06 19 ( P a g e Wellhead Protection Plan-Part 2 Draft October 2012 The MN DNR is implementing groundwater monitoring conditions to appropriations permits in order to monitor this change more closely. Rosemount is aware that falling regional groundwater levels cast some doubt on the very long term (century scale) sustainability of the source aquifers even though there are potential recharge areas within Rosemount's DWSMA. Rosemount is supporting the monitoring program through the ongoing water level monitoring in the two observation wells near Well 14 and the one at UMore Park. One more observation well is planned at the time of this report. As discussed in the previous section,proposed aggregate mining may potentially impact groundwater in the Jordan and the City is taking an active approach to mitigating risks that mining and reclamation may impose to the water supply. This includes approval of a groundwater monitoring plan specific to mining operations. II. IMPACT OF CHANGES A. WATER USE Rosemount's Comprehensive Plan identifies population grow of approximately 42,000 by the year 2030.As demand increases,new wells will be constructed in the Jordan Sandstone formation.The City has planned for two weilfields;one in the south west area of Wells 7,8, 9,and 12;and the other in the northeast area of Wells 14 and 15.The next 2 wells are anticipated to be in the northeast wellfield.However,growth in the UMore area may necessitate the construction of a future well in the UMore area. To reduce the need for additional wells,the City has a policy of encouraging water conservation through education of its residents and an inclining block rate structure. B. INFLUENCE OF EXISTING WATER AND LAND GOVERNMENT PROGRAMS AND REGULATIONS There are a number of existing rules and regulations at the Federal,State,County,and Local levels requiring regulations related to managing wells,storage tanks,and other land use issues within the system's DWSMA. Federal and State Regulations All tank operators and owners must comply with both federal and state regulations for underground storage tanks.At the federal level,tank operators and owners for underground storage tanks(USTs)must comply with 40 CFR Part 280-282. At the state level,operators and owners must comply with Minnesota Rules,Chapter 7150.Enforcement of state and federal regulations is the responsibility of the Minnesota Pollution Control Agency(MPCA).The existing federal and state regulations provide adequate controls to manage underground storage tanks within the DWSMA. Above ground storage tanks (ASTs)which store liquid substances that may pollute the waters of the state are regulated by Minnesota Rules,Chapter 7151,if the site capacity is less than one million gallons.Above ground storage tank regulations are also enforced by City of Rosemount,MN WSB Project NO. 1582-06 20 p P a g e Wellhead Protection Plan- Part 2 Draft October 2012 the MPCA.Existing regulations provide adequate controls to manage storage tanks within the DWSMA. In addition to the MPCA,the state and local fire marshal also regulate tanks. Dakota County Regulations Dakota County has land use ordinances in place that can aid in the regulation of possible contamination sites.The County adopted the Dakota County Comprehensive Plan"DC2030" in May of 2009 which outlines the County's role in addressing land and public infrastructure issues within the County.The Comprehensive Plan describes overall objectives and policies that are designed to guide the County toward the accomplishment of its visions by the year 2030 and has specific information relating to surface water management and sustainable communities including contaminated sites and other green infrastructure.Additionally Dakota County adopted an update to the 1992 Groundwater Plan in 2000 that contains more than 100 initiatives on various aspects of groundwater protection. Primary objectives include information and education,abandoned wells,pesticide issues,industrial issues, aquifer and wellhead protection,and groundwater supply.The updated Plan also includes a groundwater inventory and long-range management goals for groundwater-related issues. Dakota County collects and maintains data related to surface water and groundwater.This information can be utilized by communities throughout the County to gain a deeper understanding of the groundwater conditions in their jurisdiction.Funding programs for sealing unused water wells are also available through the County,as well as numerous education and outreach opportunities.The County also supports the Dakota Soil and Water Conservation District in its programs to assist County residents in protecting and conserving natural resources. City of Rosemount Regulations The City of Rosemount controls water and land use within the City through the enforcement of their Zoning Ordinances and other provisions of the City Code.The land in the DWSMA includes portions of the City of Rosemount and is zoned as shown in Figure 7A,Appendix B. Other official controls available to the City of Rosemount for regulating land use within the DWMSA include performance standards such as shoreland management regulations and wetland standards and health and sanitation codes,including individual sewage treatment system (ISTS)standards.Stormwater standards are also implemented throughout the City and within the DWSMA. The Wellhead Protection Plan,along with other controls listed above,are anticipated to be adequate in managing land use activities for the purposes of wellhead protection within the portions of the DWSMA in the City of Rosemount.Any deficiencies noted will be addressed and corrected in future revisions to the Wellhead Protection Plan. City of Rosemount,MN WSB Project NO. 1582-06 21 ' Page Wellhead Protection Plan-Part 2 Draft October 2012 Empire Township Regulations That portion of Empire Township within the DWMSA area is zoned as shown in Figure 7B, Appendix B,and generally includes area of agricultural,low density residential, commercial,public/institutional,mining and industrial land uses. Official controls available to Empire Township for regulating land use within the DWMSA beyond Zoning Ordinances and the Comprehensive Plan include performance standards such as floodplain and shoreland management regulations and wetland conservation standards and health and sanitation codes,including individual sewage treatment systems (ISTS)private well standards.Stormwater management standards are also implemented throughout the Township and within the DWSMA. Empire Township adopted the 2030 Comprehensive Plan in August 2009.Land use changes in this area will be present,as the area within the DWSMA will is guided for gravel mining activities through the year 2030.Existing controls are anticipated to be adequate,but monitoring of the gravel mining activities will need to a priority. City of Apple Valley Regulations Zoning and building permit ordinances and regulations are the primary means by which the City of Apple Valley controls land use.That portion of the City of Apple Valley within the DWSMA area is zoned as shown in Figure 7C,Appendix B. Other official controls available to the City of Apple Valley for regulating land use within the DWMSA include performance standards such as shoreland management regulations and wetland standards and health and sanitation codes,including individual sewage treatment systems(ISTS)and private well standards.Stormwater standards are also implemented throughout the City and within the DWSMA. These controls,along with provisions outlined with the City's 2030 Comprehensive Plan, are anticipated to be adequate in managing land use activities for the purposes of wellhead protection within the portions of the DWSMA in the City of Apple Valley.Significant changes are not anticipated in the portion of the DWSMA within the City of Apple Valley within the 10-year period of this Plan,and existing controls are anticipated to be adequate. City of Lakeville Regulations The City of Lakeville uses zoning and building permit ordinances to regulate land use.That portion of the City of Lakeville within the DWSMA area is zoned as shown in Figure 7D, Appendix B. Additional official controls available to the City of Lakeville for regulating land use within the DWSMA include performance standards such as shoreland management regulations and wetland standards,as well as health and sanitation codes.Stormwater standards are also implemented throughout the City and within the DWSMA. City of Rosemount,MN WSB Project NO. 1582-06 22 P a g e Wellhead Protection Plan- Part 2 Draft October 2012 The City's 2030 Comprehensive Plan guides that portion of the City of Lakeville in the DWSMA for medium density residential land use,where current land use allows agricultural and gravel mining activities.Monitoring of reclamation and restoration of these areas will be critical as future residential development occurs,however existing controls are anticipated to be adequate. Vermillion River Watershed Joint Powers Organization Regulations Dakota and Scott Counties formed the Vermillion River Watershed Joint Powers Organization (VRWJPO)to implement the 2005 Watershed Plan.The Watershed Plan leads the development and implementation of policies,programs,and projects that protect and preserve water resources in the 335-square mile area that drains to the Vermillion River and its tributaries. The Watershed Plan provides the management goals,policies and objectives that the VRWJPO will use to protect,improve,preserve,and manage water resources in the Watershed,and the need and reasonableness for standards,rules,and ordinances to enforce the objectives of the Plan. In addition to the Watershed Plan,the VRWJPO adopted a set of Watershed Standards in October 2006 and Watershed Rules in March 2010. The Standards and Rules assist in accomplishing statutory purpose to protect, preserve and manage surface and groundwater systems within the Vermillion River Watershed.Most notable interrelationship is the hydrology of the Vermillion River and the potential changes associated with anticipated urban development in the area. Although not the local government unit(LGU)for the communities within the DWSMA, standards and rules established by the VRWJPO provide guidance and best management practices by regulating the improvement or alteration of land and waters within the Watershed. C. ADMINISTRATIVE, TECHNICAL,AND FINANCIAL CONSIDERATIONS The City of Rosemount will have adequate resources available to regulate the public water supply's source water.Funds to support ongoing wellhead and source water protection efforts will come from the City's water utility fund.Wellhead and source water protection activities will be evaluated on an annual basis,and any changes in the focus of the tasks will also be evaluated to determine if additional funding will be necessary to accommodate the changes. For this Plan to be effective,the City will need to collaborate with other surrounding and overlapping jurisdictions and agencies to raise public awareness of the issues affecting its public water supply through public education programs.Therefore,a number of the wellhead and source water protection actions in this Plan will include public education. Increasing water demand resulting from an increasing population will make is necessary for the City to expand its public water supply system in the future.City staff continues to City of Rosemount,MN WSB Project NO. 1582-06 23 j P a g e Wellhead Protection Plan-Part 2 Draft October 2012 evaluate the water distribution system as the community grows.In addition to constructing additional municipal wells,additional storage reservoirs,water treatment facilities,and water distribution systems will likely be needed as well. The decommissioning of existing and/or the installation of additional municipal wells in the next 10 years will affect the size and shape of the WHPA and DWSMA for Rosemount's municipal wells.The City intends to amend and update its Wellhead Protection Plan at the time new wells are constructed and put into service. It is also important for the City of Rosemount to continue to work with the Empire Township,the City of Apple Valley,and the City of Lakeville to manage the portions of the DWSMA that extend into their jurisdictions.In addition,the City of Rosemount intends to work in conjunction with Dakota County and neighboring communities to protect the source water resources as much as possible when it is beneficial and logistically feasible. City of Rosemount,MN WSB Project NO. 1582-06 24 1 P a g e Wellhead Protection Plan- Part 2 Draft October 2012 CHAPTER THREE ISSUES,PROBLEMS,AND OPPORTUNITIES(4720.5230) I. LAND USE ISSUES, PROBLEMS,AND OPPORTUNITIES A. SOURCE WATER AQUIFER Part 1 of the WHPP determined that the WHPA and corresponding DWSMA for the source aquifer range from low to high vulnerability to contamination and therefore some locations are more likely to be affected by land use activities.Land use and zoning regulations can protect the quality of the aquifers by discouraging types of construction or activity that may cause contamination.Rosemount and other communities in the DWSMA have land use and zoning ordinances in place that could be revised in the future if needed to address potential contaminant sites.Additionally,Rosemount has a Comprehensive Plan in place that includes policies for managing growth of the City,the allowable land uses,water supplies,and wells. Policies identified in the Comprehensive Plan will help protect the City's source water aquifer.The challenge to Rosemount is the fact that portions of their DWSMA is located in other communities and outside of their control.Cooperative participation in the management of the local aquifers to help assure sustainable water supplies for all users is a challenge and an opportunity. Rosemount will continue to see growth within the DWSMA and therefore may consider additional high capacity wells before 2030.Additional high capacity wells in the City's DWSMA may impact the delineated WHPA's and necessitate the updating of the DWSMA. The City will work with the Wellhead Protection Consultant to amend this Plan as required by the MDH when additional municipal wells are installed.In addition,if private high- capacity wells are installed in the source water aquifer within or near the DWSMA there could be changes to the shape and extent of the WHPA and DWSMA delineated for this Plan. The ongoing collection of data has been identified as an opportunity to support future wellhead protection efforts. B. GROUNDWATER QUALITY Groundwater pumped from the Jordan Sandstone aquifer by the Rosemount municipal wells is currently free of pathogens and disease-causing organisms.In addition, Rosemount's public water supply currently meets or exceeds state and federal water quality requirements.For aesthetic purposes,the City treats the water,by chemical addition at the wellheads,to prevent precipitation of iron and manganese in the distribution system.The presence of tritium in some of the wells (discussed previously)is not a health risk,but an indication of the vulnerability of the aquifer. Well water quality sampling will need to continue so that possible contamination can be identified.There are numerous private wells within the DWSMA and will need to continue City of Rosemount,MN WSB Project NO. 1582-06 25 Page Wellhead Protection Plan- Part 2 Draft October 2012 to be regulated.Coordination with other local units of government in the DWSMA and MDH and DNR to share and maintain information on wells and potential contaminants will be a challenge and an opportunity. Education of landowners,especially those with private wells,individual sewage treatment systems(ISTS),or other contaminant sources such as storage tanks, will be important in the control of contamination affecting the groundwater quality. C. DRINKING WATER SUPPLY MANAGEMENT AREAS Land use found within the DWSMA include agricultural,single family residential,multi- family residential,commercial,office,industrial,institutional,parks/recreational and open space,and gravel mining.Potential contaminant sources identified are of concern and need to be monitored. As previously mentioned,a concern for the City of Rosemount will be that it does not have legal capabilities to regulate activities in areas within its DWSMA that are outside Rosemount's city limits.In addition,Rosemount does not have authority over water appropriations within its DWSMA and relies on the DNR to address issues related to pumping of the aquifer. Some opportunities identified include: • Working with other municipalities in the DWSMA and government entities to share information,and create policies that prevent contamination of aquifers. • Tracking the potential contaminant source and updating the list of potential contaminant sources as new information becomes available. • Landowner education and proper well management. • Routinely monitoring for land use and potential contaminant source changes within the Inner Wellhead Management Zone(IWMZ),200ft radius around well,in consideration of State Well Code requirements. • Place high priority on new and existing wells identified in the IWMZ and One Year Time of Travel Area for the implementation of best management practices. II. ISSUES,PROBLEMS,AND OPPORTUNITIES DISCLOSED AT PUBLIC MEETINGS AND IN WRITTEN COMMENTS At the beginning of the wellhead protection amendment process,the City of Rosemount sent a notification to other local units of government of its intention to amend their wellhead and source water protection efforts.After approval by the MDH,Rosemount sent copies of the Part 1 report to the local units of government The City was not informed of any issues,problems,or opportunities by the local units of government during that time.In 2003,the City of Rosemount adopted Part 2 of the WHPP. City of Rosemount,MN WSB Project NO. 1582-06 26 1 P a g e Wellhead Protection Plan-Part 2 Draft October 2012 III,ISSUE,PROBLEMS,AND OPPORTUNITIES RELATED TO THE DATA ELEMENTS Part 1 and Part 2 of Rosemount's Wellhead Protection Plan have utilized current local and regional information available for compiling and assessing data elements.At a minimum,this Plan will be revised or updated every 10 years as required by the Wellhead Protection Rules and the most recent and accurate data will be utilized at that time.To support on-going wellhead protection efforts,the City will collect data on wells,water quality and land use within its DWSMA. Due to limited resources to independently collect the full range of data and recreate the necessary databases,the City will continue to mainly rely on databases maintained by the State and County agencies to obtain data and verify data,as needed. IV.ISSUES, PROBLEMS,AND OPPORTUNITIES RELATED TO STATUS&ADEQUACY OF OFFICIAL CONTROLS,PLANS,AND OTHER LOCAL,STATE,AND FEDERAL PROGRAMS Numerous controls,plans and programs exist that may be used to achieve the wellhead protection goals identified in this Plan.State and local units of government currently enforce land use ordinances,zoning laws,sewer ordinances,well permits,and groundwater use appropriation permits.The City will continue to work with Empire Township,Apple Valley,and Lakeville to ensure proper management of the portion of the DWSMA that extends into their respective municipality.It is anticipated that most local issues may be adequately addressed through these existing processes and adopting of best management practices. The wellhead protection team does not recommend any additional regulations be imposed at this time.However,the team does recommend that overall regional coordination of wellhead protection efforts be initiated. City of Rosemount,MN WSB Project NO. 1582-06 27 ( P a g e Wellhead Protection Plan-Part 2 Draft October 2012 CHAPTER FOUR WELLHEAD PROTECTION GOALS(4720.5240) In accordance with Minnesota Rules 4720.5240 this section must address goals for present and future water use and land use to provide a framework for determining plan objectives and related actions. Goals outlined in this part were selected based on the information gathered and compiled from the data elements,delineations of the WHPAs and DWSMA,results of the vulnerability assessments, results of the PCSI,expected changes in land and water uses,identified issues,problems,and opportunities,and evaluation of this information. The public water supply is considered to be vulnerable.In addition,portions of the amended DWSMA extend into the Empire Township,City of Apple Valley and the City of Lakeville.Therefore, the goals and objectives of this Plan will focus on managing potential contaminant sources within the DWSMA,reducing the potential contaminant pathways to the source water aquifer that may be provided by private wells,educating property owners and water supply users,and working with Empire Township,Apple Valley,and Lakeville to ensure proper management of the portion of the DWSMA in their respective community. The City of Rosemount's WHP team has identified the following goals for implementation of this Plan: GOAL 1:The City will work to maintain or improve the current level of water quality so that the municipal water supply will continue to meet or exceed all applicable state and federal water quality standards. GOAL 2:The City will work to continue to supply sufficient water quantity for system users and emergency needs. GOAL 3:The City will provide and promote activities that protect the source water aquifer that provides water to the municipal system.This will include increased public awareness of the Wellhead and Source Water Protection Program and groundwater-related issues,and management of the identified potential contaminant sources and conveyance mechanisms within the DWSMA. GOAL 4:The City will continue to collect data to support future wellhead and source water protection efforts. City of Rosemount,MN WSB Project NO. 1582-06 28 ' Page Wellhead Protection Plan-Part 2 Draft October 2012 CHAPTER FIVE OBJECTIVES AND PLANS OF ACTION(4720.5250) I. OBJECTIVES Given the issues,problems,and opportunities discussed in Part Three and the goals stated in Part Four,the Wellhead Protection Plan delegates direct management efforts to the following areas to prevent future contamination of the aquifer and increase awareness of groundwater protection: A.
