O Box 90 Navarre, Minnesota, U.S.A. 55392 (612) 471-8407 On Saturday, November 11, I was invited by Dr. David Dunlap to view a proposed dredging project on Crystal Bay at Bohn'& Point. Dr. Dunlap proposes to remove about 50 cubic feet of sand using the suction dredging technique so as to facilitate access to a small lagoon. The entrance to the lagoon has been silted up over the yearn, as a result of power boats mcving sediment towards the Bohn's Point shoreline. The site where Dr. Dunlap proposes to pump the sediment is adequately contoured so that water losses will occur primarily by evaporation. If Dr. Dunlap uses the suction dredging technique, then for sllch a ama!' ainount of sediment, there will be minimal disturbance to the ecosystem. In fact there are certain ecological advantages to the program suggested by Dr. Dunlap. (1) Dr. Dunlap will not have to construct a lengthy dock to provide access to i lake. There are obvious aesthetic aspects to elating back on the numbers of docks of this type. (2) The small lagoon will be accessible to spawning fish, especially northern pike and crappie. At the present time it is not accessible. (3) If the lagoon is not opened to the lakt it will -lowly develop Into a mosquito breeding ar.a with stagna•it water. Although I recoKnize that br. Dunlap has access to Crystal Bay already on his lakefront, in my opinion his project is a small one which has aesthetic as well as environmental merit. I Y ra sincerely, / J M. Wood sector A PUBLIC'. NON PROFIT FOUNDATION 0 CONTRIBUTIONS ARE 'Ax OEDUC�TIOLE RESOLUTION NO. 1028 A RESOLUTION APPROVING A CONDITIONAL USE PERMIT FOR DREDGING BY DAVID DUNLAP WHEREAS, the Clity of Orono is a municipal corporation organized and existing under the laws of the State of Minnesota; and WHEREAS, the City Council of the City of Orono, hereinafter "Council" has adopted Ordinance 125, Ordinance 167, Ordinance 179, and Ordinance 213 all for purposes of regulating filling, grading, dredging, excavation and construction within the Flood Plain and Wetlands Conservation Area, which area is defined as including all areas below the ordinary highwater elevation of Lake Minnetonka; and WHEREAS, David Dunlap has applied for a permit to dredge approximately 200 cubic feet of material from the mouth of a lagoon on his property, legally described as Lot 1, Lydlard's Park; and WHEREAS, said application has been reviewed by the Planning commission and the City Council; and WHEREAS, Section 31.830 of the Orono Municipal Code requires a determination that the application is in the public interest prior to issuance of any permit, NOW, THEREFORE, BE IT RESOLVED, that based upon the information submitted by Mr. Dunlap and based upon the review of the Planning Commissio. and Council, the City council hereby makes the following Findings of Fact: I. The lagoon was dredged in 1950 pursuant to DNR Permit 50-8 which permitted _reation of the existing harbor and channel imposed as a condition thereon that the same "shall be considered public waters and shall be left open and unobstructed for navigation by the Public', Paragraph IV thereof. 2. The lagoon mouth has gradually closed over the las'. 28 years by encroachment of a natura' sand blanket in the area. Resolution No.1028 Page 2 3. The present channel depth of less than half that required in the permit constitutes an obstruction to navigation by the public. 4. Current DNR rules as a matter of general policy disfavor dredging and channeling in public wators but make express exception for maintenance dredging of channels to existing boat harbors, 6 MCAR 1. 502 2 B.2.b and 'lurther reflect a policy to protect the existing natural character of public craters and their existing shorelands, 6 MCAR 1.5022 A. 5. The Council has repeatedly made findings that any dredging is detrimental to the lake, but previous dredging permits have been approved by the City Council for maintenance of riparian rights. While the applicant has other riparian shore, the shoreline is extremely shallow requiring an unusually long dock to reach n•ivigable water depth. Use of the harbor for boat docking rather than construction of a long dock on the shallows lak eward from other riparian access of the applicant mitigates intrusion of visible man-m8de improvements on the lake and avoids a navigati(nal impairment on the main lake. 6. The existing harbor and channel constitute a pre- existing non -conforming use and the request for maintenance dredging therefore constitutes maintenance of a non -conforming use rather than its enlargement or replacement and therefore complies with City ordinances governing non -conforming uses. 7. The applicant proposes to accomplish the dredging by means of suction dredging with on -site disposal cr clam shell dredging with off -site disposal. A. Freshwater Biological Research Foundation report on dredging in Lafayette y, Lake Minnetonka, dated October 30, 1978, states that "clearly, suction dred, i ng for ch.-jnnel ma i nt ena ice is mmich less deleterious to the body of water than traditional dredging practices". Resolution No. 1028 Page 3 The applicant has identified a spoils disposal site on his property which will contain the spoils without direct runoff back into I.ake Minnetonka thereby reducing the imoi-nt of nutrients released in the lake. 8. Non -dredging may or may not create wetlands, but even if it does that the process may entail years of open, stagnant water with mosquito breeding, stench and other possible nuisance aspects injurious to neignboring property owners and the public. NOW, viF:REF'ORE, BE 1T RESOLVED, that the City Council of the City of Orono hereby approves the application of David Dunlap for a Conditional Use Permit to dredge approximately 200 cubic feet of material from the mouth of the existing harbor on his property, finding that such dredging is required to maintain reasonable riparian access to the property, subject to the following stipulations: 1. Dredging :hall be limited to maintenance of the channel within the scope o` the original DNR permit and shall be done by an approved niel hod. 2. Spoils disposal Shall be generally in the area shown on the attached map, Fxhibit A. Prior to start of the dredging, the spoils disposal area shall be staked uit and diked by hay bales or similar methods to prevent immediate runoff of water into the wetlands. If ninoff water volume exceeds the capacity of the disposal area dike, the culvert under the Bohns Point Road sh 11 be temporarily plugged to prevent direct runoff into the channel toward Crystal Bay. In no case shall runoff be allowed to run directly west into Crystal Bay. The spoils disposal are» shall be seeded no later than forty-five (45) days after the end of the dredging and shall be reseeded in the spring of 1980 ai required to assure full erosion control. 3. if dredging is done by clam shell rather than suction, the spoi1g shall he removed from the site ind disposed of In a I)NR ipprc>ved disposal site. Resolution No.1028 Page 4 4. The approval of this dredging in no way provides additional riparian access rights to Lots 1 or 2, Lydiard's Park, b-yond those rights existing prior to the dredging. The affected owner of said Lot 1 specifically agree: `o limit all docking to one dock per lot accorc:ing L, the ordinances of the C-ity and the I.MCD. The applicant further agrees to limit all docking on his property to one dock in the harbor and to install no docks lakeward on his property so long as he is entitled to maintain the harbor and channel in accordance with its original dimensions and so long as lake levels permit the same to yield three feet of clearance, with the stipulation that the limits herein imposed shall not prohibit the launching of watercraft directly into the main lake from applicant's property or the mooring of watercraft as buoy(s) all subject to existing or future rules and ordinances governing same. S. This permit is conditioned upon permit approval by the MCWD and the DNR. The Applicant hereby agrees to these conditions.

Rd. Wayzata, MN 55391 Dear Mx. Ulrich: PERvUT 86-6178, CNE WaL, FOJNEPLN Enclosed is Permit 86-6178 which permits the appropriation of water for the purpose of heating and cooling on a continuous basis in Section 8, T117N, R32W. Please read all the conditions of the permit, especially Condition 3.b. This requires you to record the amounts of water appropriated. A Water Use Report will be sent to you each January for reporting the amounts for the previous year. The report must be submitted with the processing fee by February 15 of each year. The fee schedule is $5.00 per each permitted ten million gallons or fraction thereof. The permit authorizes the appropriation of 11 million gallons per year; therefore, the annual processing fee is$15.00. Do not send the report and fee urtil notified. Failure to submit the report and fee can result in the termination of the permit. Pursuant to Minnesota Statutes, Section 105.44, Subds. 3 and 6, the applicant, the managers of the watershed district, the board of supervisors of the soil and water conservation district, or the mayor of the city may demand a hearing on the Permit provided the demand for hearing and the bond required are filed with the Commissioner within 30 days of receipt. A corporate surety bond or equivalent security in the amount of S500.00 must accompany the demand for hearing, however, the applicant may be responsible for hearing costs up to $750.00. No bond is required of a public authority which demands a hearing. If no dem,:nd for hearing is made or if a hedrTng is demanded but no bond is filed, the Pe alit shall become final at the expiration of the 30 days and no appeal may be taken to the State Court of Appeals. Bond forms will be supplied at your request. PERMIT NO...d�6 / 7 (� APPROPRIATION AND USE OF WATER C� WORK IN THE BEDS OF PUBLIC WATERS (Applicant) By The COMMISSIONER MINNESOTA DEPARTMENT OF NATURAL RESOURCES POST CONSPICUOUSLY AT PROJECT SITE May 13, 1986 Regional Hydrologist DNR-Division of Waters 1200 Warner Road St. Paul, MN 55106 TO WHOM IT MAY CONCERN: Because of the combined application for geothermal and vaintenance dredging we felt a letter of explanation might help to clarify -ur request. After speaking with Ms. Boudreau she explained that both permits could be covered by one application. During our phone conversation Ms. Boudreau was not aware of the filter cloth and pre -washed sand that we hope to it,stall around the interior of the lagoon. As the pond sits in its present condition there is a considerable amount of muck and silt which creates an unsafe condition for children. Our intention is to remove this muck and silt and to replace it with a filter cloth or fabric with pre -washed sand on top to give the bottom a more solid foundation. This, we hope, would eliminate the chance of accidental drowning due to soft bottom and allow even a small child to pull himcelf out of the water.

The seawall plan ahould include the detail information submitted when the existing wall was built. The certification by the engineer should not contain the term "appears to be adequate". The Owner's engineer should check out the design and certify that what is proposed meets standard design criteria. The foundation drain plan should be modified to stop the drain field 10 feet short of the lake share. The drain the should then ae connected into a dis- tributor box and an overflow line provided. The heat pump discharge line plan should provide the following additional information: 1. Average discharge T. Peak discharge 3. Velocity of water exiting holes in last pipe length 4. Method of anchoring to lake bed 5. Improved profile information with station of point elevations indica- ted include station at lake shore 6. Well data-de,,th, size, capacity 7. Discharge temperature of water - summer and winter The depth of the discharge li e is shown approximately 5 feet below the noreal water elevation. Is this adequate clearanr.e for boats wh'ch operate within 100 feet of the lake shore? The owner will also need a DNk permit for instrl- lation of the discharge line in the lake bed. 5706d 30 Year Anniversary City of Orono Orono, Minnesota Re: 139-1040 Ulrich June 11, 1986 If you have any additional q,.eations please contact this office.

Ulrich, 1595 Bohn's Point Road - Conditional Use Permit/Variance Pertinent Ordinances: 1. Section 10.03, Subdivision 19 - A conditional use permit is required to excavate within the 0-75' lakeshore protected area. Geothermal heating and cooling system will involve excavations for drain pipe trench extending into the lake bed. DNR requires permits for all alterations of lake beds or structures placed within the lake bed. 2. Section 10.03, Subdivision 8 - Development Restricted - The code specifically forbids any excavations or structures within 75 feet of the lake; the applicant must apply for a variance. Planning commission Action Staff has been in contact with John Noble, applicant's representative, to advise that the application is incomplete, but in addition to advise that staff will not recommend any action on this application until staff receives preliminary review findings from the DNR. Planning Commission is to table all action on this application until the appropriate staff members, consultants and other reviewing agencies are p-epared to make recommendations on the proposed improvement.

Wood 11/13/78 Exhibit L - Plans for Geothermal Heating/Cooling System Zoning File 11039 June 12, 1986 Page 2 of 4 Review of Application The application is two fold. The first part deals with the geothermal heating and cooling system and the second part deals with a request to dredge the lagoon and place a filter fabric on the altered bed of lagoon and then covered with 1 foot of sand. The first part is clearly under the joint jurisdiction and review of the DNR and City. The second part is solely under the jurisdiction of the DNR. Staff has reviewed the dredging application with Noble and Judy Boudreau of the DNR rnd both have confirmed that dredged materials will not be placed on '_he Ulrich site but will be removed from cite by Minnetonka Portable Dredging. In addition staff advised Boudreau that the City of Orono granted a conditional use permit to the previous owner, David Dunlop, for the dredging of the lagoon providing a minimum 3 foot draft for Dunlaps boats in 1979. The orginal DNR permit .nd resolution have been enclosed for your information. Staff noted the following to Boudreau: 1. App_.icant requests 5' to 6' depths - appears to exceed 4 feet minimum depths allowed under DNR standards. 2. Applicant has ample area c,- main lake with ability to install 100 feet length docks to seek desired depth for navigation of boats. 3. Filter fabric/sand bed will effect natural xpawning grounds of northern pike and crappie (review letter from J.M. Wood, F.W.B.I. dated 11/13/78 written for David Dunlap's revs -w). Boudreau has .vised that she will keep staff posted on the dredging phase of the application but she noted the Fisheries Department has already said no to the filter fabric and sand bed in the lagoon. Dredging to depths in excess of 4 feet presents real concern for their department because applicant has ample area on the main lake to construct a dock. The geothermal system will provide an economical system to heat and cool the new re&idence. The water supply will be ground water pumped from a well. The water will be circulated through the house providing either heating or cooling and then discharged via V underground PVC and ductal iron piping that would extend 100 feet into the lake. The pipe would be placed 5 to 6 feet under ground ind enter the lake bed approximately 50 feet from the shoreline located 412"* below the high water elevation. The discharge portion of the submerged pipe (last $0 feet of iron pipe that extends into lake) will consist of 64 3/4 inch diameter holes. Staff has asked Noble to submit the following information: tr Zoning File i1039 June 12, 1986 Page 3 of 4 1. Average daily discharge/peak discharge (in gallons per hour). 2. Velocity of discharge as it enters lake through perforations. 3. Supply line specifications - casing, size, depth of well. 4. Pump size - specs on pump. 5. Profile of discharge pipe station/elevations/percentage of grade. 6. Temperature of discharge water - winter/summer 7. Method of anchoring ends of discharge line. 8. Depth and location of 100 feet discharge line - in lake. In addition, staff. advised Noble of our concern with navigation 100 feet from shore with the discharge pipe structure at 4 feet depth. Staff is unable to determine if there is any affect on ice cover with warmer dicharge water :,eing dispersed at 4 feet depth. 171iis must be addressed for City in order to deter- mine if there is any liability to City in approving such a pipe not to mention liability for owner. Staff has checked with the following agencies to determine if applicant must seek additional approvals: a) DNR - Ground Water Division - reviewed application with John Fax and he advises that until he knows the volume of daily discharge, that he is unable to determine if permit is required. Applicant must contact Ground Water Division to determine need for permit John Fax 296-0509. b) DNR - Fisheriea - Boudreau will advise applicant if additional. review is required by this agency. c) PCA - Division of Water Quality - Curtis Sparks advised that a permit is required to discharge ground water into lake. The permitee must submit information as to the following: 1. heat vel - temperature of. discharge 2. use add'tives in water 3. flow or discharge rate Zoning File #1039 June 12, 1986 Page 4 of 4 Sparks advised that this permit review would determine if there is any affect on the stability of ice cover. Applicant should contact Gary Kimble 296-7238 for permit information. d) Hennepin County Environmental Group advised that permits are not required by their agency.

In addition, a representative from DNR's section of Fisheries will be visiting the site this week. Several issues/questions have burfaced since your application was submitted of which I would like to advise you. 1. A previous permit application (/80-6006) was submitted by David Dunlap for the purpose of dredging the same lagoon. Fisheries review at that time indicated ideal largemouth bass spawning habitat. The permit was limited, therefore, to excavation of the entrance of the lagoon. Fisheries review this week will attempt to prove or disprove the previous opinion. 2. DNR regulations limit the depth of dredging for navigational channels from the shore (for recreational watercraft) to 4 feet (Minn. Rega. 6115.0201, Subp. 4A). Although greater depths bsve been authorized for docking of keel boats, the navigability to the mooring location was not an issue. 3. 1 as not aware of a permit issued for the existing permanent dock. This application can include the review of the dock in its existing configuration or, if dealred, in a redesigned version. 4. The approval of the retaining wall should not pose a problem except that retaining gall permits require title -registration. Mr. Reep is ismiliar with this process. AN EQUAL OPPORTUNITY EMPLOYER ..1A. i N William Ulrich PA 86-6287 June 18, 1986 Page -2- S. The outlet pipe for the groundwater heat pump is of concern to DNR as well as the City of Orono. Although I understand that the manufacturer claims no impact to overlying ice thickness, we are concerned about liability. We therefore encourage redesign of the outlet system to the lagoon area where there will be less chance of public use of the lake surface. Thank you for your consideration of these matters.

The Minnesota Pollution Control Agency (MPCA) is presently seeking authority to administer a general permit program for heat pump and non -contact cooling water dischargers from the U.S. Environmental Protection Agency. A general permit is a generic permit that allows us to process dischargers of a similar nature without issuing individual permits, thus saving processing time. In order to meet heat pump general permit criteria the discharge must be less than 100,000 gallons per day and not use water treatment additives that we would regulate. The MPCA is presently accepting permit applications for dischargers in this category in the interim until final program approval is received. W" presently have several hundred applications for heat pumps and non -contact cooling water discharges that fit into the general permit category. We anticipate that there are many more heat pump dischargers that we need to locate. Enclosed are two copies of a Shortform C discharge application and one set of instructions. Fill out both copies of the application, keeping one for yourself and send the other to us. If you have any further questions, please contact me at (612) 296-7238.

William Ulrich LOCATION: Orono, Minnesota To the best of my knowledge and ability the followi:iq information is made available for your review. The figures that I am presenting are estimates only. Actual performance and conditions may vary due to unpredictable circumstances. The equipment specified for this application is TETCO Ground Water Heating 6 Cooling Systems. The equipment is manufactured in Delaware, Ohio. TERRA -THERM Inc. is the Distributor for the above mentioned equipment. Utilizing information that we have compiled from previous applications. On an energy efficient designed home we have found that one unit can handle up to 5,000 sq. ft. of living area. We know, bTsed on the above square footagu that one unit would have a run time of approximately 2,000 hrs. each year. The Ulrich residence is approximately 30,000 sq. ft.. Under optimum design conditions we would need 6 units in this home each running at 6,000 hrs. per year. The average water flow per unit would be 6 gpm. 1. With this information we can determine ti,e amount of water to 1-s utilized. 6 units x 2.000 hrs. x 60 min. x 6 gpm. - 4,320,000 gal. 4,320,000 g.il. 1 270 day -(normal heating season) - 16,000 qal. 16,000 gal. j 24 hrs. - 666.67 gal. 666 gal. 60 min. = 11.10 gal. In this residence we find 12 different systems. Each system �ndependantly zoned. The calculated Heat loss is 400,000 t3TU's. I selected an average winter temperature of 170 abuv-t zero and a worst weather temperature of -18 below zero. Using 17C above 00 the 12 zones would require 31 gpm. on an average. The average run time per unit would be 25 minutes out of an hour. Remember this will be staggered run time so all units will not be running at the same time. The average daily discharge at 170 above ,00 would be 19,344 gal. per day, or 806 gal. per hr., or 13 gal. per minute. Page 2 r Using -180 below 00 as the lowest temperature the 12 zones would require 50 gal. per minute on an average. The average run time per unit would be 41.minutes. Again, remember this will be staggered run time so units will be cycling. The average daily discharge at -180 would be 2,106 gal. ?er hr., or 35 gal. per minute. Based on information from she U.S. Weather Informational office we spend only 50 hrs. in this design condition. Assuming an incoming water temperature of 500. The discharge water temperature in the heating season will be 39 to 400. Assuming an incoming water temperature of 500. The discharge water temperature in the cooling season will be 57 to 600.

Those changes arc: 1) Constructing the new slip on the north aide of the existing dock, rather than the south side. This alignment would avoid any disturbance to the vegetated portion of the lagoon which the DNR Aquatic Nuisance Coordinator has found to be of value for largemouth bass spawning habitat. There appears to be less need to dredge to the north as well, as most of the soundings show a 3} foot depth or greater. 2) Although there does not seam to be a real need for rearranging the existing dock alignment just to add a slip to the north, we have no objection to the design as shown. I have overlayed the proposed and existing layouts with a northerly slip in mind and found that approximately 8 additional pilings would have to be installed than the number shown for the proposed location. 3) It is my understanding that the Watershed District has limited the dredging to 100 feet from shore. We, too, feel this to be a reasonable distance. The channel bottom width, however, cannot e:cceed 15 feet (MN. Rules, Part 6115.0201 Subp. 4A), and .+e recommend any revised plans portray this limit. As we discussed by phone last week, we w.il review the groundwater discharge pipe under a separate permit in order to expedite the approval of application 87-6016. Please call me if you have any questions or concerns with regard to the above requirements.

DNR: Contact was made with John Fax of the DNR and the appropriate information submitted. We were issued the Appropriation and Use of Water Permit 86-6178, which authorizes the pumping and discharge of 11,000,000 gallons vearly. j"3'T' G 2. PCA: Discharge application forms were completed and sent to Gary Kimble of the MPCA. The MPCA is presently Reeking authorization to issue a general permit program for discharges less than 100,000 gallons per day which constitutes a negligible environmental impact. Per my phone call with Mr. Kimble, August 4, 1986, we have satiPfied the necessary requirements, and the PCA will advise if any changes occur. El[WITQ 3. LMCD: Clifford Reap, acting as our agent, h`s corresponded with Frank Mix& and the LMCD. Mr. Ktxa stated chat they have no jurisdiction in thin area, and feels the other regulating agencies will answer any environmental concerns. The following information has been gathered from experts involved with geothermal heating systems: 1. & 2. Average doily discharge/peak discharge (in gallons per hour), and velocity of discharge as it enters lake through perforations: These two items are explained on the same graph and also on the Information submitted by Terra -Therm, Inc. gvLi�ts Et f Cr 3. Supply line specifications - comings, size, depth of well, aquifer tapped effects of water table: 9itk4LI-rs N _ The supply of water will be taken from a private well. The well consists of 8" - 6" casing and a total depth of 322 feet. The aquifer tapped is the Prairie du Chien Jordan aquifer. In it** #9, the well record states that static water level is 65 feet. This means water is sitting in the cosinx h5 faei below land surface. It** 010 states that water level remained at 65 feet after a 20 hour period of pumping at 200 ga!!ors per minute. Conclusion. neglible drowdown after extended pumping schedule. i2- Page QI:�, The Prairie du Chien aquifer supplies the 3,000 square miles seven countl metro area with 801 of ground water pumped for public water supply. 152,500,00 gallons are pumped daily from this aquifer. That is approximately 7,500 tines more water than we are using. These figures clear'y reveal the magnitude of the Jordan aquifer and the gallons of water available. The U.S. Geological Survey, titled: "Water Resources Investigations Report 83-4237", talks of the "hydraulic connection" of area surface lakes and this underground water supply. This "hydraulic connection" completes a cycle of water being extracted for pub'ic consumption and replenished by these surface lakes. The geologic cross -sectional map verifies the location of the Jordan aquifer and Lake Minnetonka above, thereby allowing this hydraulic connection to occur. The geothermal heating system now becomes an effective environmental heating and cooling alternative by re-cyling water used. 4. Pump size - specs on pump: Red Jacket brand, submersible pump. 10 horsepower. Three-phase power. Pumping capacity of 150/gallons per minute. 5. Profile of discharge pipe station/elevations/percentage on grade: Attached are drawings from George Shoppe showing pipe going into the lagoon. A( "_-V 6. Temperature of discharge water - wint.er/summer: Temperature of discharge during heating season: 39-40 degrees. �- K Temperature of discharge during cooling season: 57-60 degrees. -EtLL,4y—L This is explained in the information submitted by Terra -Therm, Inc. 7. Method of anchoring ends of discharge line: f4k.Lr-- IK Since the dfs�:harge pipe has been re -designed to go to the lagoon, anchoring to lake does not apply, but a similar anchor and stand w?I1 be used In the lagoon, drawing is included. 8. Depth and location of 100 feet discharge line - like. Does not apply after re -design of discharge pipe. 9. Submit Ilbt of hardships since applicant seeks d variance from the City: SURFACE DISCHARGE 1. Natural drainage system of the Ulrich property and adjoining properties would be over extended and undue erosion of said properties could occur. 2. Tax hydraulic capacity of the existing pond located on southeast corner of Lot 1, 1595 Bohn's Point Road. 3. Contamination and degradated water guallty by carryltw on shore nutrlents Into the lake. 4. Open water may occur causing dangerous 1iabi11ty sltuat'on.

The purpose of the meeting is to answer 'he questions and address the concerns that some of the neighbors have indicated in the past regarding the geothermal system being installed in my new home at 1535 Bohn's Point Road. I have asked Mr. Dean Buendorf, Vice Pre9ident of Tarr -Therm, the manufactuter of the geothermal system, along with other knowledgeabl professionals, to give a presentation and a slide show, explaining the Geothermal system as an alternative method for heating and cooling. Your presence at the meeting would be welcomed, and will assist in our future efforts to relay information regarding the geothermal system, and enhance their knowledge and understanding of its functian and safety. It would be very helpful to us in planning adequate space and refreshments if you could RSVP by calling Jihn Noble or Gloria Car', i at 541-9344 ext. 578.

Staff :gas advised Mr. Noble that this presentatior, may be reachediled before the regularly scheduled meeting of the Planning Commission at 7:30 with the scheduled review of application no. 1039. Judy Boudreau reports that a formal permit from the DNR Division of Waters will not be required. Review Exhibit A. Boudreau shares the same concern with the City regarding the impact on the ice by the temperature of the discharge. Applicant has relocated discharge pipe to lagoon to remove question of applicant's liability. Department of Fisheries has reviewed the discharge issue in relation to spawning area within lagoon and finds no harmful effects. Zoning File #1039 August 14, 1986 Page 2 Staff's only concern with Boudreau's finding is that permit 86- 6178 was issued by the DNR on April 22, 1986 (Exhibit C). Staff specifically asked in the Local Unit of Government response (Exhibit Q) that the DNR delay all action until the City's review is completed dated June 11, 1986 - form recieved by City 5/19/86. The City never received the same material for permit review 86-6178 and yet note in that letter of approval that the mayor of the City may call for a public hearing within 30 days. Staff has reviewed this matter with John Noble who had correctly assumed that the DNR would have taken care of this through normal procedural review. He advises that the well had to be drilled before the DNR would consider the permit (this has been confirmed by staff) and that the well serves not only the geothermal use but will serve the more intense needs cf the residence. Staff has had difficulty tracking down John Fax because he has been transfered to a different division. Clearly, this is not a problem related to the applicant's doing but a failure of communication between the two levels of government. Staff will resolve thin matter with the DNR. The issue has been reviewed in this memo because certain members have addrer--ed the installation of the well and the unvsual timing of the installation. Issues for convideration: 1. Could the discharge pipe have been deEigned to drain into wetlands to the east - without creating drainage problems for surrounding properties? 2. Is Planning Commission satisfied that City's only Jurisdiction over this specific application ib the excavation and installation of underground lines within the lakeshore protected area. It would appear that both P.C.A. and the DNR are satisfied with the use level and well specifications For ground water use. 3. Are there other areas in this review that should be considered as part of the City's review? Staff has asked that an engineer from Bonestroo, Anderlick i Associates be present to respo.id to any questions you may have regarding the relevance of the technical information submitted in response to our specific questions. Please contact my office prior to the meeting if any member has additional questions. It Planning Commission is ablt to make a recommendation upon satisfaction that all applicable standards have been addressed, refer to Section 10.09, 10.00 and 10.55, Subdivisior 25 A for direction in m %.ing the necessary findings fc: action - note you would be dealing with both a c-r, iit Iona l use permit and variance.

The wel will not have a significant impact on other wells in the area nor on th ater table. 2. There will not be ar• dP affect on Lake Min tr- a as a resul' he velocity or tempera -� of water di 3. Because the dischar is in the bottom A the lagoon, there will rnavig.itional hazard to traffic on Lake Minnetcnk 4. Because it is a close] sys- ',-e-e will be no pollution hazard. Mr. Humphrey noted that tt ystew which the applica:.r has choacn tc use is a permitte. system.

Humphr, iewed the other egenc a approval ollows: DNR - They have issued the well permit that has perni.tted the installation of the well and also the use if the water for heating and cooling. Dept of Fisherier - They find no harmful effects from L he wat *- discharged i n .c the lagoon 1 MINUTES OF THE PLANNING._^.OMMISSION MEETING HELD AUGUST 18, 1986 9 ULRICH CONTINUED Pollution Control Agency - Applications on this level o. sage ;+re being permitted and monitored. LMCD - Concerned regarding the possibility of a de- icing effect. They have the authority to prohibit the use of this system if it causes a de-icing effect. Dean Buendorf of Terra -Therm stated that they have installed over 1800 systems in Minnesota. He noted that they are oasically for residential use but have also installed for commercial operations. He noted that there was a similar system currently in operation on Bald Eagle Lake in White Bear Lake. He stated that that system '^as not created a de-icing effect. Planning Commission recommended that staff contact the owner of the system in 'Ahite Bear Lake for more understanding of this system. George Shoppie stated that based on his experience and his research calculation, he stated the discharge pipe will not create a de-icing effect. Bellows asked `aim if the the discharge pipe might prevent the ice from forming in the first place. Mr. Shoppie stated no because the freezing action is greater than the thawing action of system and during the time of year whet; the ice is freezing, the system is not operating at full capacity. kovegno questioned the v•;, l .dity of a lin-, r equal velocity over the entire 20' of pipe. Mr. Shoppit -tatted fac'_s that supported nis finding that the pressure would be equal. City Consulting Engineer MiXe Lynch s4inorted Mr. Shoppie in his finding stating that the difference would be negligible. MCDQ^eld expre6ged concerns with setting a precedent by allowing this type of system and the impact on the 3eke if many of these systems were installed. Addr Ting McDo aid's concern. Cliff Reep stated the. ther. culd be little impact on the lake level due to evaporation and contol by the Gray's Bay Dam. MINUTES Olt '!'ES PLANNING COMMISSION MEETING HELD AUGUST 18, 1986 _ w ii. 39 ULRICB CONTINUED Wo Goetten stated that she would like input from the Freshwater Biological Institute regarding this type of system. Chairman Kelley stated that if the system is approved, I., would like the City to review the system on a yearly brsi„ in the winter months to check on the ice issue. Rovegno recommended that erosion control conditions be included if the system is approved. Hanson stated that he had no problems with the system and felt comfortable due to all the regulatory agencies involved. Councilmember Frahm stated that he also wo,ild like comments from the FWBI on this system. McDonald voiced concerns regarding the aquiftr and running out of water. It was moved by Chairman Kelley, seconded by Rovegno, ' recommend arproval of the conditional ub permit/variance for construction of a pipe within 75' of the lake, subject to the following conditions: 1. City be allowed to review the operations of the system for a period of 5 years on a yearly basis. 2. City receive favorable written documentation from the FWBI on their ^-)inion regarding the effects on the lake and aquafer. 3. City will close the operation if the system causes any de-icing effect. 4. Appropriate erosion control measures be taken during construction of the pipe and at the entrance of the lagoon. ..)tion, Ayes 3, Nays 3. Goetten, Be 1 l 7.1s, and McDonald voted re . Goet.. stated that she felt t►i;.s matter should be tablet' until the information from FWBI is received. Bellows stated that although she is for this type of system, she feels there is a problem with no basis of a hardship to support the request Chairman Kelley stated that the issue before them and the intent of the code is to protect the hardcover within the 0-75' zone and by digging a hole, placing a pipe and refilling the hole back to its original state will not increase the hardcover. 3 MINUTES OF THE PLANNING COMMISSION MEETING HELD AUGUST 18, 1986 #1039 ULRICH CONTINUED McDonald stated that two precedents would be set being 1) allowing the system without proof of hardship; 2) opening up this type of system being allowed for everybody, of which impact concerns her. Goetten stated thAt she agreed with McDonald, she is concerned about the aqu.Lf er. She noted that she feels there has been ..nough variances, conditional use permits, land alterations etc. on tijs property and she refuses to grant anything else. #1056 OLAI HANSON 1390 RAILROAD AVENUE VARIANCE COWTINUATION OF PUBLIC HEARING 7:34 - 7s50 Olai Hanson was present for this matter. Assistant Zoning Administrator Gaffron explained the conflicting surveys. He submitted the survey which staff feels they are bound to accept as the correct survey from Mr. Hanson. This survey shows the Golden garage over onto Hanson's property. Frances Golden was present for this met ter and stated that he protests this application in.t stil I, maintains that his survey dated in 1950 sho �i be h;,,,ored due to the statute of limitations. Chairman Kelley stated that the Planning Commission must act on staff's recommendation of the correct survey and if Mr. Golden does not agree with their recommendation, he should get his facts in order and submit them to the City Council and City Attorney. Mrs. Golden stated that they felt the proposed garage would be detrimental to their garden. Rovegno suggested that the Planning Commission eliminate discussion on which survey is correct and act on a reasonable comp-omise location i.e. 7' frcm lot line rather than the proposed 4' from lot line. Mr. Hanson stated that to move the gai ie over to the 10' setback line would create a problem wi ti maneuvering the car into the garage and spoil the backy.rd. Bellows stated that she agreed with applicants reasons on the garage location. chairman Kelley asked why the garage could not be placed 4' to the south. 4 10. This permit is permissive only.

ROAD COWDITION7IL USM PZRKIT/VAitIANCE City Administrator Bernhardson explained the request for a conditional use permit and variance to install an underground pipe within the lakeshore protected area for the purpose of transporting waters used in a geothermal heating/cooling system to the lake. He noted that a memo from Mr Ulrich's attorney was hand delivered this day. Staff recommends tabling this matter in order to review Attorney Thomas Humphrey's memo and pending consultation with FWBI and a University of Minnesota groundwater specialist. Present for this matter were: John Noble, Clifford Reep, Gregory Halbe--', and Neil K. Johnson. Attorney Hr j, rt wished to review Attorney Humphrey's (who was L able to attend) memo. He pointed out the following issues: 1. The City has no jurisdiction over the installation and use of the geo-thermal heating/cooling sy.,tem for Mr. Ulricn's residence. He noted that they have obtained the necessary permits and/or authoriziation from all other agencies. 2. The only issues before the City are the issuance of a use permit and variance for the installation of a pipe across the 75 foot setbeck area from Lako Minnetonka. He noted that applicant has already been granted a variance and conditional use permit for placement of the foundation drain within the -5 foot lakeshore setback area. 3. Sufficient hardship exists so as to justify the issuance of a variance for installation of the subject pipe. 4. Granting of a variance for the installt.tion of the pipe shall not violate any of the criteria set forth in Subdivision 25 of the City Code. 4 "' ftid" 7W OF THE RSI:ULAR ORONO COUNCIL MEETING HELD SEPTEMBER 8, 1986 •1039 WILLIAM J.

Assistant Zoning Administrator Gaffron explained that this item was tabled at the August. llth meeting after a 2-2 tie vote to approve the combination of the two parcels and grant I,:-�ditional use permit for guest house use. Mayor Butler suggested the alternative of constructing the G-stall barn on one of the properties and granting a variance to keep up to six horses as long as Mr. Maxwell controls both parcels of property. She s-ated that she did not agree with the concept -if eliminating the lot line and allowing a guest house use because it is cr sting a potential problem in the future with two entiroly separate residences. Mr. Maxwell reviewed the history of the prop_. and utated that he requests to put the property back itr original statL - one parcel. He stated that he agrees and understands that he can not rent out the other residence. Jack Ebert reviewed the direction .,- the Planning Commission and Counc:i 1 has given theno s ..ice June, which led them to this particular request, to this point. 5 TO: Mayor Butler Mark Bernhardson, City Administratot Orono Council Members Planning Commission :Members 77MI Jeanne A.

Ulrich, 1535 Bohns Point Road - Conditional Use Permit/Variance seviea of Application - Applicant seeks a conditional use permit and variance application to install an underground pipe within the lakesYore protected area for the purpose of transporting waters used in a geothermal heating/cooling system to the lake. The underground pipe will run from the house to the lagoon area. The well that will serve the system is 6 inches in diameter and 322 feet deep (Prairie du Chien - Jordon Aquifer). This has been a difficult review for both the Orono staff and Planning Commission because as lay persons on such matters, we must depend on the opinions and testi nony of varied levels of experts. The :majority of experts contact`d so fa- in this review have all claimed a negligible impact on Lake Mi ietonka with no impact on the aquife2 The experts consulted as follows: PCA; DNR; Terra The n Corporation (enginee— staff); City Engineer; Cliff Reep, private consultant; and Prank Mixa, LMCD. The attached staff memo and exnibits highlight mucl. of the factual information sought to assist in the review (specifically refer to Exhibits A i B). --,e Planning Commission drew a split vote on this one. A) Recommendation of approval based on the following findings: !. Limits of ordinance deals wish excavation within 75 feet of lakeshore and increases in hardcover. The application involves no increases in hardc • _:r and land area will be restored to original state. 2. State agencies issue permits for ground water uses at specific levels - City appears to have no authority but only to assure that required state permits are applied for. 3. All other appropriate agencies find negligible impact on lak- in use of geothermal heating/cooling system. Zoning File #10 1 September 4, 19-, Page :! of 2 B) Recommends' -`enial based on the following findings: 1. Or.:ina .s to address or provide standards for this type pl-;--rtion - possible need to amend code if City wisher. to act on application. 2. Concern wi:.h impact on aquifier if other residents make use of this type of system. 3. Too many variances, conditions' 3e permits, etc. issued already to this newly devel property - Specific members of the Planning Commission and the Council representative at the meeting asked that Dr. Hanson of the FW13I be consulted prior to any final decision being made on this type of system. Staff asked Dr. Hanson to comment on the of of the geothermal system by a residential user. Dr. Hanson voiced major concern with the limitless permitting of such systems that draw ut:)n the :rairie de Chien - Jordon Aquifer. He advises this specific aquifer (involved with Lake Minnetonka) is already showing signs of major depletion - one example cited is the disappearance of the waterway connection between Christmas Lake and Lake Minnetonka. The depleted aquifer is drawing on the charged lake beds. Hanson claims the DNR and PCA refuse to recognize the many signs that reflect the aquifer 3s being depleted. He noted major concerns with the commercial users draining on the aquifer, specifically, noting the City of St. Paul's system. Hanson wants to have more irformation on the ecological effects on the lake with the ' ntro4t.%;tioa of • firmer or colter tempered waters on fauna and flora in the iintet or summer. Hanson has agreed to prepare a rt on the specific Ulric application for Council's review at our September 22nd meeting. r,0001 !Arts m.

At the same time, he was told that this consultant was vehemently opposed to such systems; and tinally that Mr. Ulrich's request for permit to install a discharge pipe across the 75 foot set back area from Lake Minnetonka would be continued until another council meeting. :n light of theses representations, we deem it appropriate to spt forth our position on our clients request LAI2IC1N. lIOFFMAN. DALY C` I.I\U(;Itl-:\. I:r>>. Mavor Butler and City Council Members September 8, 1986 Page 2 currently pending before the City Council. 1. The City has no jurisdiction over the installation and use of the geo-thermal heating and cooling system for Mr. 01rich's residence. The appropriation of ground r for a geo-thermal heating and cooling system is excl.usive.l, within the jurisdiction of the Minnesota Department of Natural Resources. That en,-ity, acting pursuant to authority granted to it by the State Legislature, has adopted a permit process to control facilities such as the one Mr. Ulrich is installing. Our client has fully complied with that process; and, in fact, he has received a permit authorizing installation of the well, and the appropriation and discharge of ground water for the system. The well has already been installed, all necessary permits having been obtained in advance. Orono, of all municipalities, should understand the limitation on the scope of its power in light of its experience in Welsh v. City of Orono, 355 N.W.2d 117(Minn. 1984). In the present case, as in that one, the DNR has exclusive control, there being neither express nor implied power of the City to regulate the subject matt-er. On this oasis, we object to any further del&y in the C'ity's permitting process. Furthermore, we object to any attempt by t) City to regulate our client's geo-thermal system indirectly t„ )ugh the withholding of a permit for an underground lischarge pi a into Lake Minnetonka. The City cannot do indirectly wnA, it cannot do directly, and that is regulate the installation of a geo-thermal facil'ty. The only issue remaining is the manner of discharge of the >'.er after it has circulated through the geo-thermal system. A request s been made to the City to allow construction of a pipe within theJ foot set back from Lake Minnetonka to carry the discharge water into Lake Minnetonka. This pipe is similar to the drain pipe which has been installed to direct water away `rom the foundation of the principle residence. 2. The only issues before the City are the issuance of a use permit and variance for the installation of a pipe across the 75 foot set back area from Lake Minnetonka. Section 10.03, Subdivision 19 of Orono's zoning ordinance requires a use permit to excavate within the 0-75 foot lakeshore protected area. Subdivision 8 specifically forbids any excavations or structures within that. distance without a variance. Mayor Butler and City Council Members September 8, 1986 Page 3 Mr. Ul:ici as applied for both a conditional use permit and a variance as required. Again, it must be stressed that there is nothing in the City ordinances that regulates the installation of the well itself for geothermal use; nor the volume of water it discharges. 3. Sufficient hardship exists so as to justify the issuance of a variance for the installation of the subject pipe. There are four options for the discharge of groundwater which is appropriated for the geo-thermal unit. First, additional wells can be drilled and the water can be pumped down into these wells after it is circulated through the unit. Second, the water can be discharged into a ponding area located in the southeast corner of the ajacent property. Third, a discharge pipe can be buried underground from the geo-thermal unit to Lake Minnetonka. Fourth, the water can be discharged directly on to the surface of the ground and allowed to flow overland to Lake Minnetonka. The first option, is really no option at all. When additional wells are dug, the ground water will rise in the wells and effectively prevent the draining of water from the system back dowr into the water table. Discharging the water into the ponding area in the so theast corn-:.-r <;f the property poses several hazards. First of all, this water ultimately finds its way into Lake Minnetonka. By discharging into the pond, the water will travel overland until it reaches that destination. That leaves the possibility of the water picking up pollutants and contaminants that are washed into the ditch area through which the water would flow. Additionally, there is a 12 inch culvert through which the ►pater must pass. There is a strong likelihood that this culvert will freeze in the winter time, thereby preventing the discharge water from reaching the lake. Ultimately, this would cause the system to malfunction when the pond reached its maximum capacity. Snould that culvert not freeze over, there is the possibility that as the water flows to the lake, it will freeze at the p f where it enters the lake and cause an ice buildup which would uic..vately dam the drainage ditch involved. Another option is to discharge the water from a pipe set 75 feet back from the lake. The water the.i would follow the natural water courser over the 75 foot area. Doing so, would allow the water to pick up fertilizer, soils, and the like and carry it into the lake. It is also likely that th=re could be substantial erosion. The overflow of water could cause open ice on the lake, which would be a hazard to persons using the lake in the winter time. I.ARKIN. 11O I-NIAN. DALY I.1\ll(;I?I:N, LTD. Mayor Butler and City Council Members September 8, 1986 Page 4 The only viable option is the one currently under consideration. The applicant seeks to install a four inch solid pipe from t!,c unit to Lake Minnetonka. This pipe will be buried underground; and it will not involve the addition of any surface hard cover. The pipe itself will have no adverse impact on the City. The excavation which is required is minimal. The pipe to be installed is similar to one which the City has already approved for this site for a foundation drain. The only sensible alternative fc candling the groundwater discharge for the geo-thermal unit which i; being installed is to divert the water through a pipe from the uni, itself to Lake Minnetonka. Lake Minnetonka serves as part of the aquafir from which the groundwater is originally drawn. By discharging in this manner, the water will simply be returned to its original source. The DNR has approved the discharge in Lake Minnetonka. d. Granting of a variance for the installation of the pipe shall not violate any of the criteria set forth in Subdivision 25 of the City Code There is no evidence to indicate that granting the variance requested for the pipe will: 1. Increase the height or duration of flnod water in or along Minnehaha Creek. 2. Result in the placement of an artificial obstruction which will restrict the passage of flood water. 3. Result in an incapatible land use. 4. Be detrimental to the protection of surface and ground water supplies. 5. Increase the financial burdens imposed on the community. 6. Be contrary t land use plans and planning objectives of the City. 7. Increase or cause danger to life or property. 8. Be inconsistent with the objectives of encouraging land uses compatible with the preservation of natural land forms, vegetation in the marshes and wetlands. Mayor Butler and City Council Memhers September 8, 1986 Page 5 9. Contribute to flooding or water pollution. The City has historically used is a test for the granting of a variance within the 75 foot set back area whether or not there will be any increase in hard cover. In this instance, there will be absolutely no increase in hard cover. In summary, there is no justifiable reason not to allow the installation of the sub -surface drainage pipe which is proposed. While we understand that members of the Planning Commission and perhaps members of the Council have concerns about the appropriation of ground water for heating and cooling purposes, that question is a much broader one to be dealt with by the Legislature. At this point, that body has authorized the Department of Natural Resources to protect the groundwater resources of this state. For that reasQr►, the City does not have jurisdiction over this aspect of the construction of Mr. Ulrich's residence. The hardship which exists relates to the manner of discharge of the appropriated -groundwater. The request has been mare based upon the unsuitability of the other methods available. This is not an economic hardship. We respectfully request that the City evaluate this request and apply the same standards that are used in evaluating similar requests by other residents of the community. We will be present Monday night to answer questions related to this matter. Sincerely yours, i" as B.

Minnesota 55392 (612) 471-8476 In the letter to you from Mr. John Noble concerning the use of water permit 86-6178 it is stated that 152,500,000 gallons are pumped daily from the Prairie du Chien aquifer. This amount is said to be 7,500 times more water than will. be used by the Ulrich residence. This assumes an average daily use of 20,300 gallons by the residence. If proven to be economical, it is not unreasonable to assume that 7,500 such systems would be installed and the aquifer water use would be doubled. They seem to have made the best case against this use of groundwater. The evidence I have seen indicates that the aquifer is presently being drawn dowr-. It is clear that water in most midwestern aquifers is not recharged as fast as it is used. I know of no evidence that removal of water from the aquifer and discharge into Lake Minnetonka results in recharge of the aquifer because of perfect exchange between the lake and the aquife-. If this were `rue, Minnehaha Creek would be dry, These lakes are not the majt. .;ource of rechu rge. There are many issues to be addressed before I would be supportive of the use of heat stored in groundwater for heating. If discharge was not directly into the lake, w`1at protections against erosion and nutrient loading would be required? There are many potential negative imparts that cannot address without more information. One can alter water migration by large scale p-.mr,ing. what impacts will this have on water availability and quality? Let me put the effects of groundwater depletion in the simplest terms possible. Two thirds or more of the freshwater in the continental U.S. has been ground- water. It Is used for agricultural, industrial and domestic purposes. use ine- vitably causes contamination. It is estimated that groundwater will be substantially depleted in 40-50 years. That will ]pave us with the remaining one '.`:rd of surface water that will be used three tames as much as at present. We can anti(71pate severe contamination if standards are not improved. we will face greatly increased costs for recovering the water in a �leen form. Lip: Jeanne A. Mabusth September 15, 1986 Page Two I have contended that we should charge a realistic price for water use in order to promote conservation of the earth s most important natural resource. If we did so, this use would be uneconomical. Now that I have given reasons to oppose the use of groundwater as a geothermal heat source, let me indicate the positive aspects. I firmly believe that com- bustion of fossil fuels and natural gas at present rates will lead to a greenhouse effect and deposition of toxic chemicals (including acid par- ticularly) that will dramatically impact life particularly in the southern half of the U.S. in the next century. Geothermoal energy use could partially reverse this trend. Minnesota is an energy poor state and the use of this source of energy would reduce d^mand for coal, gas "id fossil fuels. What are the alternatives? The increased use of solar energy and construction techniques that conserve energy should be supported. The longer term use cf nuclear fission to produce energy is in my mind the best solution, but requ!res enormous resources for research. I find it difficult for one city to have a major impact on this issue. We need a state, or better, a national policy on water use issues so that we do not discover that we have created an irreversible crisis. It is true that one or dozens of systems will not have a detectable impact on the aquifer. However, I assume that hose who sell these systems do not want to stop here. Our regulatory agencies historically have reacted to problems rather than have foreseen them. I hope that the impact of permitting the use of groundwater it this way receives more study than indicated in the information you sent to me. If I can be of any help, please do iot hesitate to call on me. Sincerely, R.S. Hanson Director, Gray Freshwater Biol. Inst.

Geological Survey, the U.S. Geological Survey and Twin City Testing for iuput concerning the depletion of the Prairie C,i Chein/Jordan Acquifer by random application of geothermal heat- ing/cooling systems. These experts indicate that one home pumping an average of 30 gpm of flow from the Prairie Du Chein/Jordan acquifer or even 100 such homes will have essen- tially no effect upon the acquifer. There is some concern amongst experts and regulating agencies that a concentration of "big users" may be .&using a fluc- tuation of the groundwater level within the acquifer. One such example is the City of St. Paul water system. This syste.-i has caused a noticeable flucttia- tion in the level of the acquifer due to an immense quantity of groundwater withdrawal from a relatively small area. On the other hand, Townsquare in St. Paul has a geothermal system that pumps at a .ate of 1200 gpm without regional depletion of the acquifer. The usage of the acquifer is currently being regu- lated by the DNR and the Health Department. The popularity of geotnermal heating systems for residential properties has been dying out the past couple years as there is no longer an energy credit for their use and the place -sent of such a system is generally not cost-effec- tive.

Dr. Hanson has reviewed the specific Ulrich application for a geo-thermal heating and cooling system. His letter (Exhibit B) forewarns that uncontrolled, intense, multiple uses of our groundwater reserves will not only deplete 2/3's of the fresh- water supply of our nation but will leave the remaining 1/3 of surface water severely contaminated requiring increased costs for recovering the water. In the same letter, he voices major concern with the greenhouse effect that results with combustion of fossil fuels and natural gas. Ceo-thermal enerqy would partially reverse the trend also the use of solar energy, energy saving construction and nuclear energy. Hanson concedes that a single City cannot fight this battle and suggests a national policy with standards for groundwater uses to asure that we are not creating an irreversible crisis. John Noble has submitted a list of various experts involved with groundwater -- please review Exhibit A. Staff has asked Mike Lynch (Bonestroo, Ander 1 ick S Associates) to contact as many of these expertq and report back to the City. Lynch was able to contact 3 of the 5 experts - Kanaveteki of the Minnesota Geological Survey, Schoenberg of the U.S. Geological Survey and Gabanski of Twin City Testing. Zoning File 01039 September 17, 1986 Page 2 All three find the Ulrich use to have a negligib.e eff ct on the acquifer as proposed and see no harmful effect on the lake.

E. Schoenberg The ground -water system in the Twin Cities Metropolitan Area includes five aquifers, two of these aquifc rs--the Prairie du Chien -Jordan and the Mount Simon -Hinckley —supply about 80 percent and 10 percent, respectively, of the ground water pumped for public supply. Water levels and changes in water levels in these two aquifers differ greatly in the Twin Cities Metropolitan Area. The Mississippi, Minnesota, and St. Croix Rivers are in hydraulic connection with and influence the pattern of flow in the upper aquifer, the Prairie du Chien -Jordan. Water generally flows toward these streams from water -level highs northeast, northwest, and south of Minneapolis and St. Paul. Consequently, heavy pumping has caused only localized cones of depression in the potentiometric surface of this aquifer. In contrast, the Mount Simon - Hinckley, which has only a slight hydraulic connection to the streams, is greatly influenced by pumping. Pumping in the urban centers of Minneapolis and St. Paul has caused a large cone of depression in the Mount Simon -Hinckley potentiometric surface. During 1971, the measurable cone was centered in east - central Hennepin County, was about 25 miles in diameter, and was as much as 150 feet deep at its center. Between 1971 and 1980, average water levels in the Prairie du Chien -Jordan aquifer changed less than 5 feet in most of the study area, but rose or de- clined as much as 25 feet locally in response to pumpage and recharge. During this period, seasonal declines of water levels from winter to summer lessened, and the area where these declines exceeded 10 feet decreased In contrast, between 1971 and 1980, average water levels in the Mount Simon -Hinckley aquifer rose as much as 60 feet in the center of the cone of depression in response to decreased pumping. Also, the measurable cone of depression contracted from about 25 miles to about 15 miles in diameter. How- ever, because of increased summer pumping due to below -average precipitation during 1980, seasonal water levels declined much more and over a w`der area during 1980 than in 1971. Water -level data suggest that (1) little variation in annual pumpage between 1971 and 1980 from the Prairie du Chien -Jordan aquifer produced gener- ally stable water levels in that aquifer, (2) decreased annual pumpage from the Mount Simon -Hinckley aquifer from 1971 to 1980 caused water levels in that aquifer to rise, arxj (3) a greater seasonal ..vmpor*nt of pumpage from the Mount. Simon -Hinckley aquifer than from the Prairie ;u Chien -Jordan produced larger and more widespread seasonal water -level declines in the Mount Simon -Hinckley than in the Prairie du Chien -Jordan, particularly curing dry years. 1 The ground -water system in the Twin Cities area contains five aquifers (Guswa and others, 1982, table 1). Two of these aquifers, the Prairie du Chien -Jordan and Mount Simon -Hinckley, supply about and 10 percent, respec- tively, of the ground -water pumped in the 3,000 mi seven -county area (fig. 1). 7his report describes water levels and water -level changes in these aquifers in the Twin Cities during the period 1971-80. State and local agencies, industries, and municipalities need information on water levels and water -level changes caused by pumping to anticipate the effects of increased pumping on the aquifers. For example, ground -water with- drawals have caused water -level declines of about 200 ft in the Mount Simon - Hinckley aquifer and 90 ft in the Prairie du Chien -Jordan aquifer since 1885 (Reeder, 1966; Norvitch and others, 1973, p. 118). In addition, water, levels decline sharply during summer as pumping increases and recover during winter as pumping decreases. To provide the needed water -level data, the U.S. Geological Survey, in cooperation with the Metropolitan Council of the 'twin Cities and the Minnesota Department of Natural Resources, measured water levels in wells throughout the Twin Cities area during winter and summer 1965, 1971, and 1980, summer 1977, and winter 1978. These water -level data will also be used to calibrate a digital ground -water -flow model of the Twin Cities area (Guswa and others, 1982). This report documents water -level data collee--d during winter and summer 1980 for the Prairie du Chien -Jordan and Mount Simon -Hinckley aquifers and compares the data with those collected during winter 1971. Specific objectives are to (1) compare short-term and long-term changes in water levels in the two aquifers, (2) examine the effects of major pumping centers on water levels over the 1971-80 period, and (3) describe ground -water -flow patterns in the two aquifers. This report contains a trief description of the hydrologic setting, a description of the water -level observation network and methods used to col- lect data, water -level mapb for winter 1971 and winter and summer 1980 for both aquifers, seasonal and long-term water -level -change maps, and hydrographs of selected wells. Water -level data for 1971 and 1980 were analyzed in detail because this was the calibration period chosen for the ground -water -flow model. In 1966, the U.S. Geological Survey released 14 maps depicting histor :al water levels and water -level changes for the Prairie du Chien -Jordan and Mount Simon -Hinckley aquifers in Uie Minneapolis -St. Paul Metropolitan Area Reeder, 1966). The maps show water levels for both aquifers for 1885, 1949, 1959, and 1%5 and changes in water levels from 1885 to each of the subsequent years. Norvitch and others (1973) provide water -level maps for both aquifers for winter 1970-71 and for the Prairie du Chien -Jordan for August 1971, and water - level -change maps for the Prairie du Chien -Jordan for December 1970 to August 1971 and winter 1%5 to winter 1970-71. Hult and Schoenberg (1981) p ovide more detailed water -level data for both aquifers for 1979 in a 110-mi area surrounding St. Louis Park, a western suburb of Minneapolis. In addition, a report by Horn (1983) contains ground -water pumpage data that are very useful in understanding and interpreting water levels and water -level changes. Delin and Woodward (1982) constructed regional water -level maps for both aquifers in southeastern Minnesota, which includes the 'Fain Cities Metropolitan Area. The author is grateful to all the well owners who allowed measurements of water -levels in their wells, Special. thanks are given to those municipal: ties, industries, and others who turned off their pumps the night prior to a water - level measurement in their well in order- to allow adequate time for water - levels to recover from pumping. The ground -water system underlying the 'Twin Cities contains 14 geologic units that Guswa and others (1982; table 1) combined into 9 hydroyeologic units-5 aquifers and 4 confining units (fig. 2). The five uppermost hydro - geologic units are not continuous in the Twin Cities area because of erosion of bedrock units or nondeposition of drift or both Bedrock valleys deeply incise the six uppermost hydrogeologic units. 'These valleys either contain drift or form present-day stream valleys and significantly affect flow in the Twin Cities ground -water system. The Prairie du Chien -Jordan aquifer comprises two geologic units with different lithologies and correspondingly different hydraulic properties. The Prairie du Chien Group of Ordovician age is predominantly dolomite; it contains fractures, joints, and solution cavities that control the flow of water through it. The Jordan Sandstone of Cambrian age is a fairly uniform, highly permeable sandstone; flow through it is primarily intergranular. The two units act as a single aquifer because no extensive confining unit separates them. Drift -filled bedrock valleys, present-day stream valleys, or both, inter- rupt. the continuity of the Prairie du Chien -Jordan aquifer in many parts of the study area. In the major stream valleys, where the overlying confining units have been removed by erosion (fig. 2), a good hydraulic connection exists between the aquifer and the major streams. The degree of hydraulic connection between the Prairie du Chien -Jordan and these st t: eams depends on the hydraulic conductivity of the valley -fill deposits. The Mount Simon -Hinckley aquifer comprises two sandstone formations, the Mount Simon Sandstone of Cambrian age and th. Hinckley Sandstone of Precambrian age. 7bey are cont'nuous throughout the study area and have similar hydraulic characteristics. A thick confining unit, the Eau Claire Sandstone, which overlies the Mount Simon -Hinckley aquifer (fig. 2), retards 'low between the Mount Simon -Hinckley and the overlying aquifers and the surface -water system. Norvitch and others (1973) present a detailed discussion of the geologic and hydrologist properties of the Prairie du Chien -Jordan and Mount Simon - Hinckley aquifers. 4 Decorah-Pi.,'tevllle-Glenwood confining unit Ossol St. Pater Drift aquifer confining unit -Irlq du hlen-Jordan aquifer unl WEST EAST Eau Claire confining unit Mount Simon -Hinckley aquifer Not to scale Figure 2.--Schismatic hrdrogeologlc sect/on through the Twin Cities Metropolitan Area (alter Ouawe and others, 1282, fig. 2J 5 have had measuring -point altitudes surveyed to withi- 0.1 ft. Measuring -point altitudes for the remaining wells were estimated fL,xn topographic maps to an accuracy within 5 to 10 ft. The water -level altitudes used for the maps in this report, therefore, are accurate to within 5 to 10 ft, and adequately reflect regional ground -water flow. If detailed water -level data for a small local area are needed, the records of wells in that area need to be examined The accuracy of water -level data from individual wells in the network also may differ because of well --construction methods. Most wells in the network are open to the full thickness of the individual aquifer; these water levels repre- sent the average water level for the aquifer. However, some wells are open only to part of the aquifer; water levels in these wells represent only the average water level for the section to which the well is open and may differ from the average water level of the aquifer at the same point. However, water Levels from wells near each other but completed to different depths are simi- lar. This indicates nearly vertical equipotentials within the aquifers, sug- gesting that the water levels used in this report represent the altitude to which static water would rise in each aquifer. A measurement strategy was form .fated to obtain a regional picture of water levels and to investigate long-term and seasonal water -level changes. The strategy has four basic features. First, recognizi.ig that all wells should be measured simultaneously to represent the water -level surface at an instant of time, measurements were made over as short a time as possible (about 3 weeks). Secondly, measurements were made so tnat all wells within a pumping center were measured within a day or two, rather than over the 3-week period Thirdly, municipal and other high -capacity wells were turned off the night before water -level measuuensents were made so that localized, short-term effects of pumping were minimized. Finally, water 7wels were measured twice during the year, once during winter (January -February, when pumping was at a minimum and once during summer (August) when pumping was near maximum. In the Twin C_ties area, ground -water withdrawals in summer are commonly more than twice the withdrawals in winter because of use of ground water for air conditioning, lawn sprinklinq, and crop irrigation (Horn, 1983). IFMW LEVE S AND 11=t--•iZVISL. (WAM IN IM PMURN W ®I AQIIM The maps on plat- 1 (A, B, and C) show that water levels in the Prairie du Chien -Jordan aquifer are highest (more than 900 ft above sea level) in nortt�Prn waah,r.gton County, central Hennepin County, and southern Scott and Dakota Counties. The lowest water levels (less than 700 ft above sea level) occur along the Mississippi River where the river leaves the southeastern corner of the study area. The water -level contours indicate that ground water generally flows from the water -level highs toward the major streams, the Mississippi, Minnesota, and St. Croix Rivers. The water -level contours also indicate that water flows toward some smaller streams, such as the Vermillion and Cannon Rivers in the southeastern part of the study area. This general flow pattern indicates that the major streams in the Twin Cities area are the principal. 7 natural points of discharge for ground water in the Prairie du Chien -Jordan aquifer. Water -level contours on maps ;„ B, and C on plate 1 that locally are irregularly shaped or closed indicate that major pumping centers disrupt the natural flow pattern in the Prairie du Chien -Jordan aquifer by diverting ground water enroute to the major streams. In some areas, such as near the depression in the water -level surface in southwestern Ramsey County (pl. lA and 1B), pumping may have reversed the natural direction of flow and caused water from the Mississippi River to enter the aquifer. However, despite heavy pumpage that averaged about 154 Mgal/d from 1976 through 1979 (Horn, 1983, table 7 , the water -level surface of the Prairie du Chien -Jordan aquifer has no large cones of depression. This indicates a highly transmissive aquifer (Woodward, 1984) that is in good hydraulic connection with the overlying drift and the major streams. Water -level changes in the Prairie du Chien -Jordan aquifer between 1971 and 1980 (pl. 1E) were detertr`ned by comparing water levels measured during January -March 1971 (pl. UU with chose measured during January -February 1980 (pl. 1B). Water levels measured during winter were chosen for this comparison because they seem to represent "average" annual water levels and because water levels are fairly stable during the winter months. Plate lE shows that water levels in different parts of the Prairie du Chien -Jordan aquifer rose as much as 20 ft and declined as much as 30 ft between winter 1971 and winter 1980. Water levels rose more than 5 ft in eastern Dakota County south of the junction of the St. Croix and Mississippi Rivers, throuyl"ut most of Washington County, in central Ramsey County, and in eastern Hennepin County. Water levels declined more than 5 ft in central Dakota County and in central Hennepin County. The greatest water -level changes are centered around single wells, and reflect reductions or increases in ground -water pumpage by .industries and municipal] ities. For example, the rise in water levels in northeastern Dakota County near the Mississippi River is due to reduced pumpage by the meat -packaging industry in that area (Horn, 1983, fig. 1). Also, the water -level declines in asatral Fmimpin County are probably cue to increased pumping from the Prairie du Chien -Jordan aquifer by suburban municipalities west of Minneapol i a The general rise in water levels in Washingtron County is probably related to long- term climatic trends, rather than changes in pumping. This phenomenon is the object of studies by Federal, State, and local agencies because of its possible relationship to high lake levels in the area (D. C. Gillies, U.S. Geological Survey, St. Paul, Minn., oral common., 1983). Althouglh rater lr4 els cvenged si gnif i cant ly in certain parts of the 'IM iM Cities area between 1971 and 1990 (pl. 1E), hbere was no region -wide trend for the Prairie du Chierw-Jordan aquifer. This is not surprising considering that average daily pumpage from the aquifer remained fairly constant for 197D-79, averaging .152.7 Mgal. Table 1 below shows average daily pumpage for each year and indicates that pumpage peaked in 1974 arxi has declined singe then. 9 Table 1.---Annual daily pumpage from the Prairie du Chien -Jordan aquifer, 1970-7 9 (Pumpage in million gallons) Year _ 1970 1971 1972 1973 1974 1975 1976 1977 1978 1979 Pumpnge 148.3 145.2 144.5 158.2 160.4 153.2 1.59.9 156.6 152.3 148.5 Water -level trends in the Prairie du.Chien-Jordan aquifer also are appar- ent in the hydrographs of wells. However, depending on the proximity of an observation well to pumping centers and on the nature of the pumping, the characteristics of these hydrographs differ considerably. Figure 3A is a hydrograph of well 031N22W23CBCO2 in the Prairie du Chien -Jordan aquifer in southern Anoka County (location shown in pl. lE) where little or no water is pumped from the aquifer. The hydrograph shows that the water level rose slightly from 1971 through early 1976, due to climatic conditions, although the rise is hardly distinguishable from the seasonal change of 2 to 3 ft.'Ibe water level fell sharply about 3 feet in mid-1976 because of drought and rose slightly from 1977-80 as normal climatic conditions prevailed. Winter and Pfannkuch (1976) report that the Prairie du Chien -Jordan aquifer is in good hydraulic connection with se),eral lakes in the area. In addition, the levels of some of these lakes are controlled. These two factors help explain why the water level in the well has been so stable during the period of record. Several downward spikes in the lvdrograph during 1976-77 provide the only evidence of pumping. This pumping, apparently from standby supply wells in the area, affected the water level in the observation well for very short periods. Figure3B is a hydrograph of well 117N23W118BD01 in the Prairie du Chien Jordan aquifer in worst -central Hennepin County (location shown in pl. 1E). The well is at the western edge of the area west of Minneapolis where water levels declined during 1971-80 (see pl. 1E) because of municipal pumpage. 7t* hydro - graph sti ws relatively stable water levels during fall, winter, and spring of each year, but sharp declines due to increased summer pumping. It also shows that average water levels declined steadily between 1971 and 1980, acc:umulatinq a net decline of 6 to 7 ft. Water levels in the Prairie du Chien -Jordan aquifer fluctuate �*�asonally in much of the Twin Cities area, primarily in response to increased pumping during summer. Horn (1983, table 8 and fig. 16) determined that the seasonal component of ground -water pumpage varied among water -use categories and that total summer pumpage from all aquifers was significantly lar(,--�r tha.i winter pun.pege. For example, in 1978, a year with normal amounts of precipitation, August p Apage was about 2.5 times greater than February pumpage. In 1976, a very "Ay year, July pumpRge was about 3 times greater than January pumpage. The effects of seasonal pumpage are indicated in the water -level change maps on plate 1D and 1F, which show the difference in water levels between January --March and August 1971, and `)etween January -February and August 1990, V1 1 DI D V Continuous recorder D Installed Well number 031N22W23C00O2 '1 1 l I I Well number 1 17N23W 1 188001 Floor* a.--Mrlregraphs showip0 weter-lerel 10 A.

The water -level changes depicted in these maps may not repre- sent the total seasonal change for the year, because they were calculated from two sets of one-time measurements rather than continuous measurements. In 1980, for example, hfdrographs of wells influenced by pumping (see figs. 39 sari 3C) indicate that water levels recorded in July in the primary pumping center were as much as 10 ft lower than in August. However, the maps are still very useful for analyzing seasonal water -level changes on a regional basis. Plate 1D shows that during 1971 water levels declined more than 10 ft in much of east -central Hennepin County and southwestern Ramsey County and that there were two r ijor centers of water -level decline. . One was in the Edina -St. Louis Park area in Hennepin County where municipal pumping caused water levels to decline as much as 50 ft. the other extended along the Mississippi River from St. Paul to Mi.meapolis where withdrawals for air conditioning in commercial buildings caused water levels to decline as much as 70 ft. Water levels also declined significantly in a relatively small area south of the Mississippi River near West St. Paul. Water levels declined less during 1980 than caring 1971 and the area where water -level declines exceeded 10 ft was smaller (pl. 1F), despite the fact that the summer of 1980 was dryer than the summer of 1971. Maximum water -level declines were about 40 ft in the Edina -St. Louis Park area and about 50 ft in Minneapolis. Comparison of maps D and F of plate 1 suggests that the seasonal component of pumpage for the prAirie du Chien--.7ordan aquifer decrea: d between 1971 and 1980. This decrease it related to use of water from the Mount Simon - Hinckley aquifer and is discussed further in a later section of this report. Changes in water level from winter to summer are well doom., -rated in the hyirograph of well 117N21W1FCCA01 in the Prairie du Chien -Jordan aquifer (fig. 3C) at St. Louis Park in east -central Hennepin County (pl. l-) and 1F). Seasonal water -level fluctuations in this well are due c.rimarily to Dumping from municipal wells. From 1971 to 1980, the seasonal water -level changes ranged from about 10 to 30 f"t. In 1976, the seasonal change was the ;ximum for the period and the sumnwr low -water -level period was longer than ttat of other years, reflecting the extremely dry conditions and heavy pumping of that year. In contrast, the hydrograph shows a much smaller seasonal change in 1977 and water levels in late 1977 and early 1978. The hydrograph segment. of 1980 is similar to that of 1971. The net change in water level over the 10-year period was small. Figure 3D is a hydrograph of well 028W2WO6ABDO2 in the Prairie du Chien - Jordan aquifer (location shown on pl. 1E) in downtown St. Paul (pl. 1D and 1F) where water levels in the aquifer are strongly influenced by pumping for air conditioning in commercial buildings. The seasonal water -level changes are so large (as much as 70 ft) because pumpage for commercial buildings during August is commonly more than 10 times that during February (Horn, 1983, fig. 16). The magnitude of seasonal change (averaging aboat 60 ft) did not vary significantly over t.3ie period 1971-80, indicating that seasonal pumpage for air conditioning of commercial buildings imar the well was :miform over the period. The hydro -- graph shows that the average water level rose between 1971 and 1980, probably because of a decrease in total .industrial pumpage in the area (Horn, 1993, fig. 10). This rise in water levels is also indicated an plate 1E. 12 in other years are similar to those of 1971 and 1980. water -level declines from winter to summer exceeded 50 ft during 1976 and 1980 in this well; were between 30 and 50 ft during 1972-74, 1977, and 1979; and were less than 30 ft during 1971, 1975, and 1978. Figure 5 shows that precipitation was below normal during 1972-74, 1976, and 1980, and above normal during 1971, 1975, and 1977 - 79. The relation between pry -ipitation, pumpage, and the magnitude of summer water -level declines is affPc`.ed by other factors such as the timing of below - normal precipitation (winter or summer), customary use of wells ii, the Mount Simon --Hinckley aquifer, and V,-npage elsewhere in the aquifer. The Mount Simon -Hinckley and Prairie du Chien -Jordan aquifers supply most of the ground water pumped in the Twin Cities Metropolitan Area withdrawals have caused water -level declines of about 200 ft in the Mount Simon -Hinckley aquifer and 90 ft in the Prairie du Chien -Jordan aquifer since 1890. In addition to long-term water -level changes, seasonal declines occur owing to increased summer pumpage. Future problems related to lowered water levels may be avoided or reduced by informed management of the resource through a better understanding of the hydrogeology of the Twin Cities Metropolitan Area The present I-eport presents preliminary results from the current "Appraisal of the Ground -Water Rescurces of the Twin Cities Metropolitan Area, Minnesota" study and describes and interprets water levels for 1971tiand 1980 for both the Mount. Simon -Hinckley and Prairie du Chien -Jordan aquifers. The water -level data indicate that the patterns of flow in the Prairie du Chien -Jordan and Mount Simon -Hinckley aquifers differ greatly. Flow in the Prairie du Chien -Jordan aquifer is greatly influenced by the Mississippi, Minnesota, and St. Croix Rivers. In the Prairie du Chien -Jordan aquifer, water flows from water -level highs in central Hennepin, Washington, Scott, and Dakota Counties toward the major streams where it discharge`3. The aquifer supplies large quantities of water to wells in the Twin Cities area (average of 154 Mgal during 1976-79) and natural flow patterns in the aquifer are disrupted as water is diverted toward major pumping centers. However, despite heavy pumping, no large cones of depression have developed in the water -level surface, indicating that the aquifer is Highly transmissive and in good hydraulic connection with the overlying drift and with the major streams. Between 1971 and 1980, water levels in the Prairie du Chien -Jordan aquifer rose or declined as much as 25 ft locally in response to changes in the rate and distribution of pumping and in response to short-term climatic changes. However, water levels changed less than 5 ft in most of the study area and no overall trend in water levels is apparent. This is consistent with water -use data that indicate only small changes in annual pumpage from the Prairie du Chien -,Jordan aquifer between 1970 and 197 9. water levels in the Prairie du Chien -Jordan aquifer generally decline du►.,iy summer because of increased withdrawals for air conditioning, lawn sprinkling, and irrigatio. Water levels declined during 1971 as much as 70 ft in Minneapolis and more than 10 ft in all of east -central. Hennepin and south- eastern Ramsey Counties. Summer water -level declines duriiiq 1980 were less 20 than during 1971 even though 1980 was a dryer year than 1971, suggesting that the seasonal component of pumpage for the Prairie du Chien -Jordan aquifer decreased between 1971 and 1980. Water levels in the Mount Simon -Hinckley aquifer indicate that ground water flows from the northwest corner of the study area generally southeast to the vicinity of the Minnesota River and the Mississippi River north of its confluence with the St. Croix and north to that same vicinity from a water - level high south of the study area. Ground water also flows east to the St. Croix and the Mississippi south of its confluence with the St. Croix. However, the natural flow pattern is interrupted by a large cone of depression in the water -level surface near pumping centers in east -central Hennepin and southeas- tern Ramsey Counties. During 1971, the measurable cone of depress_ m was about 25 miles in diameter and 100 to 150 ft deep. The location, depth, and shape of the cone suggest that the Mount Simon -Hinckley aquifer is in poor hydraulic connection with the shallow ground -water system and the major streams. Most of the water that flows into the cores of depression may be derived from leakage through the hydrogeologic units that separate the Mount Simon -Hinckley and Prairie du Chien -Jordan aquifers. Between 1971 and 1980, water levels in the Mount Simon -Hinckley aquifer rose more than 10 ft throughout most of the done of depression and more than 50 ft in the center of the cone, which decreased in area in response to decreased annual pumpage during this period Seasonal water -level declines due to increased summer pumping generally are greater in the Mount Simon -Hinckley aquifer than in the Prairie du Mien - Jordan aquifer and are generally greatest during periods of below -normal pre- cipitation. During 1971, a year of above -average precipitation, water levels in a relatively small area declined more than 10 ft from winter to summer; maximum declines were less than 20 ft. However, during 1980, a year of sig- nificantly below -average precipitation, water levels in the Mount Simon - Hinckley aquifer declined more than 10 ft throughout most of the cone of depression with maximum declines of over 50 ft. This decline in water levels may result from use by municipalities of wells in the Mount Simon -Hinckley aquifer to meet peak demands for water, whereas wells in the Prairie du Chien - Jordan aquifer are used to meet normal demands. In total, the water -level data suggest that (1) annual pumpage from the Prairie du Chien -Jordan aquifer was fairly constant betweer, 1971 and 1980, producing fairly stable water levels; (2) annual pumpage from the Mount Simon - Hinckley aquifer decreased from 1971 to 1980 causing water levels in the aqui- fer to rise; and (3) the seasonal component of pumpage for the Mouni_ Simon - Hinckley aquifer is greater than that for the Prairie du Chien -Jordan, pro- ducing seasonal water -level declines that are larger and more widespread in the Mount Simon -Hinckley than in the Prairie du Chien -Jordan, particularly during d; y years. A large amount of data presently are available to characterize water levels and water -level changes in the Prairie du Chien -Jordan and Mount Simon- 'im_klcl aquifers in the Twin Cities area, but the current data -collection dram has some inadequacies that limit application of the water -level data. ,.If problem is that there are too few observation wells in the Mount Simon- hinckley aquifer, so that there may not be enough control points to accurately 21 define ground -water flow in the K xmt Simon -Hinckley aquifer. The configura- tion of the cone of depression may be much more complex than depicted in this report. More observation points (wells) are needed to delineate this possible complexity and to determine the mutual interference of pumping centers. This is important because the effects on water levels of each pumping center may spread far out into the aquifer. Water -.Level data for the Mount Simon -Hinckley aquifer will become increasingly important if ground -water users in the Twin Cities area develop additional water supplies from this aquifer to avoid localized contamination of the Prairie du Chien -Jordan aquifer. Another problem is insufficient water -level measurements at 6- to 8-week intervals, particularly in wells open to the Mount Simon -Hinckley aquifer. Although the measurement of a large number of wells twice in a year every 5 years may be adequate to define long-term water -level trends, this approach is inadequate for measurinc, seasonal changes. Seasonal water -level changes are large in the Twin Cities are% as water levels decline rapidly in response to summer pumping. Consequently, the extreme seasonal water levels can easily be missed by one-time summer measurements. The potential problems associated with seasonal water -level changes and the accompanying reorientation of flow patterns may be much greater than those associated with long-term changes. The present water -level -data collection program is designed for analyzing long-term trends; significantly more observation wells are needed in which water levels are measured at least monthly, as well as more wells equipped with continuous water -level recorders. Monthly pumpage data are currently (1982) available for over 60 percent (Horn, 1983, table 8 ) of the approximately 950 wells in the Prairie du Chien - Jordan aquifer and 150 wells in the Mount Simon -Hinckley aquifer for which pumpage data have been compiled However, in 1982 there were only 6 obeerva- tion wells in the Mount Simon -Hinckley aquifer and 32 in the Prairie du Chien - Jordan aquifer in which water -level measurements were made at least bimonthly. The water -level network must be d-rr_3er in order to adequately define the rela- tionship between seasonal pumpage and water levels. i� I e:rnv — 1 S.,ni Co-lPore Corns to If I I1 VMldirH•1f 1 •kf 'y In ,• 11M• Neff• i.

District Heating PPrro_eosall_1: Instruct the Minnesota Energy Agency to conduct an analysis of the cost-effectiveness of expanding existing and planned district heating systems through the use of water source heat pumps. Proposal 22: Design the proposed district heating 1 program to be flexible enough to include the use of water source 'ie;tt pumps in the district heating systems eligible for funding. -6- B. Water Use Object i ve o prevent the occurrence of water shortage problems, such as well interference and aquifer drawaown, as a result of the increased use of water source heat pumps. Pro oral l: Instruct the Department of Natural Resources (DNR) to Include regulations controlling the use of water source ,peat pumps in their existing water supply management program. Justification Water super -problems such ds aquifer drawdown and well interferenre could increase with the development of water source heat pumps. Domestic systems can use up to 7,000 gallons of water 3 day ir, cold .inter climates. Groundwater supply management programs can address potential supply oroble►,ls in "critical water areas" by requiring the use of non -consumptive closed -loop or reinjection systems, or by setting sell -spacing stanuards and pumping limits for consumptive systems. (Consumptive systems are systems that do not return the heat pump effluent directly to the water source, while non -consumptive systems eitl.er reinject thi effluent back into the source aquifer or continually circulate the same water through a "closed loop.") Discussion Unlike post riparian ,tates, Minnesota has developed a sophisticated rater use management program. i'ypically, riparian states rely on the criteria reasonable use to settle water supply disputes. Such case -by -case adjudication is unpredictable and is therefore of limited value as a planning tool. Also, few ripa-ian states have empowerea their state regulatory agencies to regulate wate, supply. In contrast, the groundwater law in Minnesota evolved into a permit system tared on priority of use. The five priorities 1 descending order are: 1) domestic water supply; 2) any use that invLlves less than 10,000 gallons per aay; 3) agricultural irriga Lon in excess of 10,000 gallons per day; 4) power generation in of 10,000 gallons per aay; and 5) other uses (i.e., comner--i,,' ind-strial) in excess of 10,000 gallons per Gay. The DNR has been empowered to conduct a nt -vstem based on this priority system. Thus, unlike most riparian state,, Minnesota has uti ned predictable criteria for settling water use disputes that can also , used for water use planning, and has granted ar agency clear statutory authv, ty to protect the public interest in regard to the water supply issues. The R already has the basic structure to address the potential for water supp, )roblems that may occur with the increased use of water source heat oumps. However, the I egislature may want to: -12- Proposal 1: instruct the DNR to include regulations controlling the use of water source heat pumps in their existing water supply management program. Additional funding or a staff position may be needed. The DNR may want to draw on the expertise of the WPB in developing its program. Regulatory parameters might include liquifer-specific well spacing and well depth standards in critical water areas or in aquifers where problems of drawdown and well interference are prevalent. Since water quality and water quantity issues are considerably interrelated, the DAR will also have to work closely with the MHD and the consumer to determine the best type of water source heat pump system for a particular water supply. At times the potential for water quantity problems may outweigh the potential for water quality problems. This is parti--ularly true in critical supply areas. C. Financial Incentives Objectives o encourage the use of water source neat pimp; through the use of financial incentives. Proposal l: Include water source heat pumps in any of the proposed renewable energy loan programs. P•oposal 2: Adopt a resolution to request the Housing Finance -ncy (HFA)'to include water source heat pumps in their home improvem�'* loan program. Proposal3: Include tax credits for water source heat pumps i;, proposals to continue the renewable energy tax -redit proram. Justification TState financial incentive proms- 4nms for the purchase and instal lativi. weatherizatir,t and alternati, enci,gy systems provide both social and economic sanctions for consumers to explore the use of these energy -saving measures. Presently, approximately forvy-four state, nave enacted some form of legislation to prov'.e such financial incentives. States are just ueginning to enhance their monitoring capabilities to assess the impact of these programs, but as yet there are no figures on the let energy savings �iializea. The National Solar Center has, however, collected information on .ax incentives that suggests that the number of state residents using these programs increases dramatically each year the incentives are in effect. In California, for examole, applications for solar tax credits grew from 5,600 in 1976 to 16,80 1978, an increase of 300 percent. Similar percentage increases were raa,, in all of the five other states that collected the relevant data {Perretta, 19W .

Ulrich, 1535 Bohn's Point Road - Conditional Use Permit/Variance - Resolution At the Council meeting of November 24, 1986, the DNR representatives from the Groundwater Division addressed your many concerns involving the use of the acquifer for residential heating and cooling systems and the discharge of the water used in this system into Lake Minnetonka. Your minutes of that meeting review their responses to your questions. Council asked that action on the application be tabled until members had an opportunity to consider the information presented to them for the first time. Staff was asked to contact br. Hanson regarding the matter of the Jischarge into the lake. In a phone conversation with staff, Hanson cited no problem with the system discharging into the lake. He questioned once again the City's effectiveness when the State grants all authority to the DNR in all matters involving use of groundwater and its discharge of waters into lakes or rivers. Council also asked if this application could be deemed a test case and initiate a moratorium to deter other such requests until the City is satisfied that these systems are harmless. Staff would remind Council that the DNR has been given all authority over matters dealing with groundwater use and discharge into lakes and rivers. The DNR may call for a moratorium if they deem a study for the purpose of amendment is necessary. If Council wised to study the matter of excavations within the U-75' setback area for the purpose of amending the code, we could le4ally call for a moratorium. Council may ask the DNR to study specific afpects of their permitting system. Staff has talked with the City Attorne} on this specific request of Council and she has concurred with staff's opi,iion:. Kathleen will be able to respond to any questions you may have on this matter. As this wi.'l be the last meetine, for this specific Council, staff seeks direction and asks that you consider the following options for action: a) Direct staff to advise the DNR that the City of Orono wishes to call for a public hearing, either to challenge such use of underground water resources or the discharge of gallons of water into the lake - or both. b) Staff has drafted a resolution approving the proposed geothermal system listing the necessary findings for your revie:, amendment and action. c) Denial of application if you feel this is a realistic option - Council would be denying the excavation within the lakeshore protected area and direct staff to prepare the necessary resolution.

Ulrich (hereinafter "the applicant") is the owner of the property located at 1535 Bohn's Point Road within the City of Orono (hereinafter "City") and legally described as Lot 1, Beth and Bridget (hereinafter "property"); and WHEREAS, per Section 10.03, Subdivision 19 the applicant has mac. eplication to the City of Orono to permit the installation of an underground 4 inch pipe that would extend into the 0-75 foot lakeshore protected area and a variance per Section 10.55, Subdivision 8 land alterations are not permitted within the lakeshore protected area. NOW, THEREFORE, HE IT RESOLVED by the City Council of Orono, Minnesota: FINDISM 1. This application was reviewed as Zoning File i1039. 2. The property is located in the LR-lB Single Family Lakeshore Residential Zoning District. 3. The property is approximately 5 acres in area. 4. On August 18, 1986, the Planning Commission action resulted in a split vote. S. '"he approving members based their recommendation on the fo11r iq findingss a) An underground pipe cannot be considered new hardcover within the protected area. b) The applicant proposed appropriate erosion control measures throughout the excavation project creating negligible impact on the lake. c) The underground pipe will outlet into the protected lagoon and not the main lake. Page 1 of 6 City of ORONO RESOLUTION OF THE CITY COUNCIL NO. 2098 6. The members in opposition based their position on the following findings: a) Applicant has not demonstrated sufficient hardship to allow the excavation within the lakeshore protected area. b) The limitless permitting of this type of system will have an impact on the acquifer. 7. The Department of Natural Resources (water Appropriations Division) issued permit 86-6178, April 22, 1986, without obtaining the required local unit of government response. The City Council has asked the DNR to schedule an appropriate public hearing tr• address the many concerns raised during the review of conditioni,i use permit. #1039, a per•tiit that would allow the use of underground water from the Prairie Du Chein/Jordan acquifer for a geothermal heating and coiling system. 8. On November 24, 1986, Hedia Adelsman and James Japs from the DNR's Groundwater Appropriations Divisicn and Judy Boudreau, DNR Area Hydrologist, appeared before Council to address the City's concerns regarding the proposed use of the acquifer and the method of discharge. 9. Ms. Adelsman advised that the Prairie Du Chein/Jordan acquifer from 1971 through 1980 has been monitored showing decreased levels at various periods but consistently recovered to remain at basically the same level. She advised that there are various wells in the Orono vicinity that are monitored by the DNR and if an irregularity was to occur that a permit for this type of residential use would be revoked or the conditions of the permit amended at any time. 10. In response to the concern that limitless permits issued by the DNR for such ge-)thermal systems would have major impact on the acquifer, both Adelsman and Japs concurred that there would be concern if they were concentrated in one area but that few residential users would ever be at the applicant's level of use. Again, they advised of the monitoring network and the ability to ►evoke such permits at any time. 11. The DWR advised the Council that the City can always present their concerns or questions to the Department regarding any single or multiple number of permits issued by the DNR. Page 2 of 6 City of ORONO RESOLUTION OF THE CITY COUNCIL NO. M City Engineer contacted Roman Kanavetski, Minnesota Geological Survey, Gil Gabanski, Twin City Testinq and M. Schoenberg, U.S. Geological Survey regarding concern for the depletion of the Prairie Du Chein/Jordan acquifer oy random application of geothermal heating/cooling systems. Their comments were summarized by Mike Lynch as follows: "These experts indicate that one home pumping An average of 30 gpm of flow from the Prairie Du Chein/Jordan acquifer or even 100 such homes will have essentially no effect upon the acquifer. There is some concern amongst experts and regulating agencies that a concentration of "big users" may be causing a fluctuation of the groundwater level within the acquifer. One such example is the City of St. Paul water system. This system has caused a noticeable fluctuation in the Level of the acquifer due to an immense quantity of groundwater withdrawal from a relatively small area. On the other hand, Townsquare in St. Paul has a geothermal system that pumps at a rate of 1200 gpm without regional depletion of the acquifer. The usage of the acquifer is currently being regulated by the DNR and the Health Departmcnt. The popularity of geothermal heating systems for residential properties has been dying out the past couple of years as there is no longer an energy credit for their use and the placement of such a system is generally not cost-effective. 13. The discharge pipe for the geothermal system will enter the lake within a protected lagoon area below the lake level at a 924.6 elevati,-n. 14. There will bt no navigational hazard:s created for the users of '.ake Minnetonka :tiPcauae the discharye pipe will not extend ii the main lake ar -aa. 15. Neither the velocity of the discharge nor the temperature of water discharged will have any de-icing effect on the main lake. 16. The proposed geothermal system is defined as a closed system requiring no additives, conditioners or other chemicals. The quality of the water to be discharged into the lake will not pose a pollution hasare. 17. Dr. Richr_rd Hanson of the Fresh Water Biological Institute has voiced major concern with the uncontrolled, intense, multiple uses of our groundwater reserves and strongly recommends that a national policy be formulated providing standards for groundwater uses to assure that we arc not creating an irreversible crisis. In his letter of September 15, 1986, he noted that he "found it. difficult for one city to have a major impact on this issue". Page 3 of 6 City of ORONO RESOLUTION OF THE CITY COUNCIL NO. 2098 - -- 18. In a letter dated December 8, 1986, D,,. Hanson advised the following: I have no objection discharging water `.nto a lagoon prior to release into Lake Minnetonka, proviaed ro rmal precautions against erosion, etc. are taken. 19. The discharge pipe has been placed to outlet into the lagoon/main lake as opposed to entering the adjacent wetlands because of the following reasons: a) There is a greater chance of the pipes freezing and making the system inoperable. b) There may be greater questions of safety or liabilities if discharge weakens ice or creates other hazards within the shared wetlands area. The lagoon area is contained within applicant's property. 20. The City Council finds that the conditions existing on this property are peculiar to it and do not apply generally to other property in this zoning district; that granting the variance would not adversely affect traffic conditions, light, air nor pose a fire hazard or other danger to neighboring properties; would not merely serve as a convenience to the applican' but is necessary to alleviate a demonstrable hardship or diff: lty; is necessary to preserve a substantial property right of the appli- cant; and would be in keeping with the spirit and intent of the Zoning Code and Comprehensive Plan of the City. 21. The City Council finds that granting a conditional use permit to allow the installation of an underground drainage pipe for a geothermal heating and cooling system within the lakeshore protected area will not be detrimental to the health, safety or general welfare of the public, would not adversely affect light, air nor pose a fire hazard or other danger to neighboring properties, nor will it depreciate surrounding property values and that the proposed level of use of the property will be in keeping with the intent and objectives of the 'Zoning Code and Comprehensive Plan of the City. CONCLUSIONS, OFMER AJW CONDITIONS Basel upon one or more of the above findings, the Orono City Council hereby grants a conditional use permit per Municiapl Code Section 10.03, Subdivision 19 to William J.

Very truly yours, /. Nancy E. Husnik Legal Assistant ITEM/jlp/3228 Rnclosures MINUTHS OF THE REGULAR ORONO COUNCIL MEETING P ELD DECEMBER 8, 1986 410 309 ILLIA14 ULRICH a5 �BOHNS POINT ROAD CONDI';IONAL USE PERMIT/VARIANCE RESOLUTION 12098 City Administrator Bernhardson reviewed that at the last. Council m•-eting, the DNR representatives :addressed the concerns :nvolving the use of the aquifer for .esidentisl heating and cooling systems and the discharge of the water used in this system into Lake Minnetonka. He noted that DNR is witholding the discharge permit pending the action on the conditional use permit by Council. Staff received a letter from Dr. Hanson of FWBI indicating that while he does have an objection to thermal energy using aquifer water, but he is not concerned about the actual discharge of the water into the lagoon. Regarding the suggestion that this application, be used as a test case and initiate a moratorium to deter other such requests, he noted that the City has no authority over the discharge into the lake, however could legally impose a moratorium prohibiting excavations within the 0-75' lakeshore setback. Present for this matter were ?ohn Noble, Gregory V-1bert, and Din Brauer (President of Brauer Group C .nniny Con3ultant). Mr. Halbert noted that their hardship is the fact that they are installing a geothermal heating/cooling system whereby a discharge area is necess&ry for th+^ system, and discharge into the lagoon ib deemed to re the least environmentally intrusive. He noted that the geothermal heating system is backed -up by a conventional system. Mayor ' er stated that she understands the di lemma., however iships are in conjunction with the land, not due to individual or desired heating system, therefore, she believes there is no JFmo, iable hardship that with the land in this case. Mr. Brauer stated that he felt t.'A.s was an unusual situr.tion, because this is not really a variance that is required, it is a regulatory problem which Orono has chosen to treat through a variance process. He stated that the applicant has chosen a certain type of heating/cooling system, which is a very efficient system. The hardship involy-d is that the applicant is not able to uti line his land to accomodat.e his choice of heating and cooling his house. Counci lmember Frahm noted that in t1ve City c. f Orono, any grading or land alteration in the 0-75' setback requires .oth a variance and conditional use permit.. MINUTES OF THE REGULAR ORONO COUNCIL MEETING HELD DECEMBER 8, 1986 j�Y'S9 ULRICH CONTINUBD ,"'" Counci1.rember Adams ,tated that because the proposed pipe Foes not result in structure or significant hardcover in the 0-75' area, he was not concerned with the demonstrable hardship arqument. Tt wds ,r,oved by Councilmember Grabek, seconded by Councilmember Frahm, to adopt Resolution #2098 granting the conditional use permit And variance to permit the installation of an unciergro*jud pipe extending into the 0-75' lskeshore protected irea. Motion, Ayes 4, Nays 1. Councilmember Callahan voted nay. #1014 GRACE BAPTIST CHURCH 2830 SHADYWOOD ROAD VARIANCE RESOLUTION #2099 City Administrator Bernhardson explained tte request for a variance for a sign. Applicant submittec a second signage plan per the directives of the Planning Commission at their first review. The proposed sign (Supra Herald I) would be 11'9" in height and 61.6 s.f. ,n area. Planning Commission voted to deny this sign plan finding the variances still too excessive and specifically rer.ommended the "Standard" Herald I siqn which would be 9' in height and 39 s.f. in area. Zoning Administrator Mabusth noted standards within the sign section of the code allowing sigr for q••F,.ai commercial uses to be 8' in height and 1 � s in area. Present for this matter were Bill Mulligan and Lowell Zitzloff. Mr. Mulligan stated that he made a survey of the signage a_ea of other church signs in Orono, and he found they f luctuate from 35 s.f. to 72 s.f. in area. They feel beca-se the church is located in a large commercial area, the larger sign is more advantageous to their needs. Mr. Zitzloff noted that they could cut down the height of the Supra sign to at -,,it 10' whereas their existing sign is approximately le' in height. It was moved by Councilmember Grabek, seco, 'wd by Councilmember Frahm, to adopt Resolution #2099 app, ving the proposed Supra Herald I sign installed at a mak;mum height of 10' requiring a 2' variance, and a sign area variance of 49.6 s.f.
