Interceptor Sewer Service Anew �° �,.Ls, as shown:, on Exhibit .A. attached hereto and.: incur porn ed. jjere'.in, by reference are.: consistent` witYi the City of 00- Orono's existing and proposed Comprehensive Land Use Plan and proposed Comprehensive Sewer Plan dated April 1., 1977. 3. All lands within the City of Orono within the rural service area as shown thereon, which are all lands outside of the MUSA, MSS•R and Interceptor Sewer Service'Area lines, as - shown on Exhibit A, will not be sewered at any time in the future. These lands are to be'zoned and regulated so that .they will be adequately and more economically served by private• on-site septic systems. 4. These restrictions and the additional restrictions as set forth in the Comprehensive Land Use Plan, proposed -Comprehensive Sewer Plan and the Zoning Code and amendments thereto'in order to implement those plans, are necessary in part for the following reasons: A. The entire City of Orono lies w•i'thin the watershed of Lake Minnetonka. B. Lake Minnetonka is totally dependent upon the"..sur= face water runoff from its watershed for replenishment and' the water quality of Lake Minnetonka is directly related to " the quality of surface water runoff within the watershed. C. The quality of surface water runoff is adversely .affected by any increase in the land use density and the resulting impervious hard cover which limits the natural purification process and which limits the removal of nutri- ents from the surface water runoff, which nutrients pollute Lake Minnetonka, the surface water recharge areas and the other surface waters in the city. Moreover, in order to pay for the extension of such expensive public sewer, a much greater density of land use development would be necessitated, which increase in land use density would result in the above -noted adverse affects on the quality of the surface water runoff. These adverse effects on the quality•of t`he ..surface water runoff are documented at length in the` Orono r•r'`' Comprehensive Land Use Plan approved by the Pet•ropolitan ' { . Council on November'7, 1974, and adopted by the City of Orono on -D_ecember 2, 1974, the Comprehensive .Sewer -, Plan" as adopted in October; "19.77, and the .e:xhibits and reports 'incor- porated therein-by=reference. 5. The "city has for years, along with other.:age.n,cies, recognized th_e problems of. dense devel-opment and •the con -comm' tant adverse affects -on the .quality. of `t•h.e surface .water ru�i; off 'in this sort -of .watershed' and. has ' therefore.. impl::emen`ted a comprehensive regulatory program of 'two ;and five acre .: ' minimum lot sizes and a thorough on-site septic system ordi- nance pursuant to the standards and specifications promulgated by the Pollution Control Agency and the Hennepin County Soil and Water Conservation District, which on-site septic system ordinance provides for mandatory pumping and inspection of all on-site septic systems, stringent standards of maintenance and construction, and provides for a method of repair and altera- tion of nonconforming on-site septic systems. Moreover, the City of Orono has hired additional personnel specifically to administer and enforce these environmentally sound regulations. 6. In addition to and separate from the concerns of the quality of surface water runoff, any greater density of development in the rural service area as shown on Exhibit A than is as found presently and as is provided for in the Com- prehensive Land Use Plan for the City of Orono would necessitate a premature, uneconomical and fiscally unsound increase in capital improvements, such as to transportation, fire and police services. 7. Before there should be any increase in density beyond that which is already provided for in the Comprehensive Land Use Plan and the Zoning Code of the city for those areas beyond the MSSR, MUSA and Interceptor Sewer Service Area lines as shown in Exhibit A, in addition to the increase and availa- bility of the .urban services, there will need to be adopted and implemented an effective environmental protection program along with the necessary public works, to among other things, insure the purification of the surface water runoff prior to its discharge into the marshes and creeks leading into Lake Minnetonka. FURTHERMORE, BE IT RESOLVED: Based upon the above findings of fact and contingent upon the hereinafter set forth actions to be undertaken by the. Metropolitan Council and the Metropolitan Waste Control Commission, the City Council of the City of Orono agrees on behalf of the City of Orono as follows: 1. To support the construction of the proposed Orono Interceptor as presently designed as shown in Addendum 3 to the Preliminary Engineering Report for the Orono Interceptor by the Metropolitan Waste Control Commission dated November, 1977, and as shown in the design plans and specifications for the Orono Interceptor dated and not to -appeal the City of Orono's Systems Statement, as long as the Metropolitan Council and Metropolitan Waste Control Commission agree as follows: -3- C -1.10 .. A. To move the MUSA line now, to correspond with the MUSA line as shown on Exhibit A. B. To move the MSSR line now, to correspond with the MSSR line as shown on Exhibit A. C. To move the Interceptor Sewer Service line to correspond with the Interceptor Sewer Service Area line as shown on Exhibit A. D. To amend the Orono Systems Statement to reflect the move of the MUSA line, MSSR line and the Interceptor Sewer Service Area line as shown on Exhibit A so that the new loca- tion may be used as a basis for the completion of the City of Orono's Comprehensive Land Use Plan in compliance with the Land Use Planning Act. This amendment would be consistent with the Orono Systems Statement proposed by Sandy Dean, the staff consultant to the Metropolitan Council, dated May 10, 1977, and transmitted to the City of Orono on May 11, 1977. E. To approve and adopt the April, 1977 Comprehen- sive Sewer Plan as an interim plan until the final adoption of the Comprehensive Land Use Plan pursuant to the Land Use Planning Act in 1980, and to use in the review of this plan the Metropolitan Council Review proposed by Sandy Dean, dated June 13, 1977, and transmitted to the City of Orono on June 15, 1977, attached hereto and incorporated hereby by reference as Exhibit B. F. To review the existing Systems Statement to con- form with the above noted Systems Statement and Review of the City of Orono's Interim Comprehensive Sewer Plan by Metropolitan Council staff member Sandy Dean. G. Agree that the ultimate design capacity, expressed in flow, residential population and number of residential dwelling units, of the Orono pumping station, Long Lake pumping station and the Orono municipal pumping stations of the Orono -Long Lake interceptor, as determined in Addendum No. 3 of the Preliminary Engineering Report for the Orono -Long Lake interceptor dated November, 1977, is as follows: (1) Orono Pumping Station total capacity: a. Average daily flow Peak factor Peak flow -4- 1.65 cfs - 1.07 MGD 3.3 2450 gpm b.

To allocate the total available sanitary sewer capacity assigned to the City of Orono only to those areas which are within the revised MUSA, MSSR and Interceptor Sewer Service Area lines as shown on Exhibit A. I. That the ultimate capacity of the Orono Long -Lake Interceptor is 1.77 MGD. The portion of the total assigned to the City of Orono is 1.14 MGD. Future planning will be based on the Interceptor Sewer Service Area line to be shown on Exhibit A and upon a flow of 115 gallons per capita per day and 3.2 people per household. 2. The City of Orono understands from Mr. John Boland's letter of March 31, 1978, that all of the above criteria are acceptable to him and the staff of the Metropolitan Council with the exception that the staff of the Metropolitan Council recommends that there is no procedure available to move the MSSR line, the MUSA line and the Interceptor Sewer Area line until all of the Comprehensive Land Use Plans of the adjacent municipalities are submitted and reviewed by 1980, pursuant to the Land Use Planning Act. The staff has also stated that it is premature to approve the Comprehensive Sewer Plan sub- mitted by the City of Orono in October, 1976, as amended in April, 1977, and on March 16, 1978, and that in lieu of approval of the Comprehensive Sewer Plan, the staff will recommend approval of a Interim Comprehensive Sewer Plan to be submitted by the City of Orono based upon the criteria set forth herein. 3. The City of Orono could appeal the Systems Statement of June 23, 1977, as amended on March 31, 1978, and could • -6- • object to and take the appropriate actions to delay the con- struction of the Orono Interceptor until such time as the Systems Statement more accurately reflects the criteria set forth herein, but such actions by the City of Orono would be inconsistent with the City's long -stated desire to cooperate with the Metropolitan Council and Metropolitan Waste Control Commission in developing land use plans which are consistent with all agencies and which will insure that the interceptor could be constructed to remove the points of pollution without having the construction of the interceptor adversely affect the environment of the area, the health, safety and welfare of the citizens of Orono, and which plans will insure that the presence of the interceptor would not mandate a location of the future MUSA, MSSR and Interceptor Sewer Service Area lines which would include areas of the City of Orono which should be in the General Rural Use Region of the Rural Service area for the City of Orono as shown on Exhibit A. • 4. Based upon the assurances of the staff of the Metropolitan Council that the above objectives will be accom- plished as soon as the necessary redrafting of documents can be accomplished, and for the reasons set forth above, the City of Orono will not appeal the Systems Statement and will grant to the Metropolitan Waste Control Commission the necessary building permits, conditional use permits and variances from the Zoning Code of the City of Orono to allow for the construc- tion of the Orono -Long Lake Interceptor, conditioned upon the following: A. The City of Orono is included in all preconstruc- tion meetings. B. The City of Orono must first approve any changes in the construction methods or pipe location which changes could or may tend to adversely affect the environment and land use in the City of Orono. C. The City of Orono shall stop the construction of the pipe if the construction is in violation of the permits issued, the ordinances of the City of Orono, the ordinances and regulations of the Minnehaha Creek Watershed District, Lake Minnehaha Conservation District, Department of Natural Resources or any other agency having jurisdiction over the construction of the pipe. 5.

Both of these items have been reviewed at length by the. City of Orono for the last several years and after numerous discussions with the staffs of the Metropolitan Council and the Metropolitan Waste Control Commission, the City of Orono believes that it is in the position to recommend approval of the Orono -Long Lake Interceptor and not to appeal the most recent Systems Statement, which decision is predi- cated upon the general guidelines as set forth in a resolution adopted by the City Council of the City of Orono on April 17, 1978, a copy of which is included herein for your review. This resolution sets forth the understanding between the City of Orono and the staffs of the Metropolitan Council and the Metropolitan Waste Control Commission and sets forth the repre- sentations previously made upon which the City of Orono has relied in its decision not to appeal the Systems Statement and not to delay the construction of the Orono -Long Lake Intercep- tor. The City of Orono would appreciate your reading the enclosed resolution prior to the meeting next Thursday so that you will be fully informed of the city's position and so that there will be no misunderstandings in the future concerning the agreements reached. • I, `4 i Mr. John Boland and �. Metropolitan Councilmembers April 17, 1978 Page Two The resolution references a packet of documents (Exhibit C) which are the underpinnings of the resolution; however, because of the volume of the documents and because they are not necessary for the understanding of the resolution, we have not included copies of them but have provided copies of them to the staff of the Metropolitan Council by separate letter. It is our understanding that a copy of this resolution and exhibits attached thereto will be made a part of the official record of the Metropolitan Council in regard to the Systems Statement for the City of Orono and the Orono -Long Lake Inter- ceptor. At your meeting on Thursday, April 20, 1978, Mayor Van Nest of the City of Orono will be present to review the contents of the resolution with you and to answer any questions which you may have. On behalf of the City of Orono, we would like to thank you and • your staff for having worked with the City Council in the past in regard to these two items and to thank you at this time for your anticipated cooperation in the future.

EXHIBIT C • _7 PREFACE During the past century, much of the lakeshore area now within the Boundaries of Orono was subdivided and developed in a relatively haphazard and unplanned fashion. Due to the lack of organized local governments during much of the period, little if any, planning to protect and preserve the quality of Lake Minnetonka was possible. The result has been pockets of small narrow lots totally incapable of supporting on-site sewage disposal systems. This led to lake pollution and public health problems from septic effluents on lots and in the groundwater supplies which problems have required Orono to complete three major municipal sewer projects, including the construction of a central sewage treatment plant. In 1955, Orono was incorporated as a Village and the first attempts were made at comprehensive planning and zoning. By 1965 the First Comprehensive Zoning Code, which established the principle of protecting and preserving Lake Minnetonka and the surrounding watershed and the groundwater supply, was adopted. In 1968, the Minnesota Pollution Control Agency, in cooperation with the Lake Minnetonka Conservation District, directed a study of Lake Minnetonka •by the Harza Engineering Company to determine the causes of pollution to the lake and to recommend a course of action. The Harza study completed in 1971 found the cause of pollution to the lake was a high input of nutrients, specifically phosporus. It further concluded that the single largest source of nutrient input at that time was effluent from the municipal sewage treatment plants, located within the Lake Minnetonka Watershed. The second single largest source of nutrients was contained in the storm water run-off from the watershed. Because Lake Minnetonka is fed by neither spring nor river tributary system, its sole source of replenishment comes from the storm water run-off of its own watershed. The recommendations of the Harza Study were to construct a system of metropolitan sewer interceptors, to -remove from the Minnetonka watershed the effluent of the seven municipal sewage treatment plants. The study also recommended that, because the storm water run-off could not be removed from the watershed, that the natural system of marshes and wetlands must be protected and preserved, as it is the only practical method of filtering'and removing the ever increasing nutrient load to the lake, the surrounding watershed, and the groundwater caused by increased urbanization within the Lake's Watershed District. The Harza Study, as well as several subsequent studies, has concluded that the nutrient input to the lake will increase as the level of urbanization increases. These studies show that greater land use density could raise the level of nutrients as much as ten times unless the present zoning, specifically the two to five acre minimum lot size in the Rural Service Area of Orono, is maintained. Other studies show that Lake Minnetonka has a slow 25 year "Flush -out" period second only to Lake Michigan in our region, which requires careful and continuous attention to the quality of the storm water run-off flowing into the lake. 1i -t• • Orono adopted a wetlands preservation ordinance in 1970 based in part on the need to protect and preserve the wetlands as recommended by the Harza .Study. The "Surface Water Management Plan" adopted in 1974, .developed an over-all detailed plan and rationale for the protection and preservation of the wetlands within Orono. A comprehensive guide plan together with a new comprehensive zoning code was also adopted in 1974. All of these plans and ordinances were developed with the protection and preservation of Lake Minnetonka as one of the foremost guiding principles. Based on the above studies and experience, Orono has determined that the cost of Municipal Sewer Service Extention into the Rural Service Area would create such an economic hardship on the land that massive rezoning would be required in order to allow sufficient population to pay the cost of sanitary sewers. Thus, it is Orono's contention that this municipal sewer cost would create a spiral which would force present land owners to subdivide and develop their land to a level of urbanization that would create an even more intolerable nutrient load to the lake than we have today. In conclusion, Orono, when furnishing municipal services, must provide them to be consistent with high environmental standards for the protection and preservation of Lake Minnetonka; for future generations. Therefore, guidance for future development policy for the unsewered areas of Orono Y is to maintain present zoning ordinances, requiring lot sizes of not less than two acres, which is recognized as the minimum capable of sustaining on-site sewage disposal systems in the types of soils located • in Orono. The lower level of urbanization resulting from this development policy will minimize nutrient load to Lake Minnetonka, the surrounding watersheds, and the groundwater supply through a more acceptable quality storm water run-off. Experience indicates the following paradox: The extension of expensive Municipal Sewer Services to reduce pollution to Lake Minnetonka, the surrounding watersheds, and the groundwater supply -generates higher levels of urbanization to pay for these services and this urbanization in turn increases the pollution of Lake Minnetonka to an even higher degree contributed by'storm water run-off. For these reasons and other land use planning factors, Orono will not extend a municipal sewer service to the Rural Service Area within the next 25 years. iii • TO: City Attorney Bruce Nalkerson FROM: ?-4ayor- Brad Van Nest DATE: January 16, 1978 SUBJECT: Orono's Comprehensive Land Use Planning At the request of the City Council, I have assembled all of the information that I have in my possession concerning the history of Orono's Comprehensive Planning as it relates to the following issues: 1. Design of the Orono -Long Lake interceptor 2. The Orono Comprehensive Sewer Plan - 3. The Metropolitan Council's Systems Statement After getting all this information together, I find that the size of this docurientation is over a foot and a half in height; and in order to facilitate your review, I will attempt to highlight the ,J -important issues in this memo. 1968: During the spring of 196-8, the Minnesota Pollution Control issued a mandate that the sewage effluent from the seven waste water treatment plants within the Lake riinnetoiika watershed district shall'be removed totally from the watershed. A study was instituted cooperation with the Lake Minnetonka Conservation District entitled The Harza Report. 1971: The Metropolitan Waste Control Commission designed.the Orono - Long Lake interceptor which was a large gravity system that not only • removed the effluent from the Orono and Long Lake sewage plants, but Cprovided a major collection system within the City of Orono to facilitate its development to a projected population of in excess of 35,000- people. Because federal funding was not available for thi �-- Page 2 1974: project, it was not constructed at that time. The City completed its Comprehensive Land Use Plan using input from the -citizens of Orono and technical information from the Harza study and other engineering studies completed in the early ComLand Use Plan showed a 1970's. The results of this Co drastically reduced population level and a reduction in the need for sanitary sewer extensions throughout rural Orono. The City at that time located its urban and rural use areas that would.guide the 1 development of the City of Orono for the next 25 years period. This Comprehensive Land Use Plan was adopted by the City Council and the Metropolitan Council during the fall of 1974. The implementing ordinances were drafted and adopted putting this ComprehensivE zoning Plan into force by January 1, 1975. november 1975: During the fall of 1975, federal funding became availab: to complete the Orono -Long Lake interceptor but the Metropolitan on was instructed by the PCA that it must Waste Control Commissi distribute the environmental impact assessment as well as hold a public hearing prior to the final approval of the Orono -Long Lake interceptor as designed_ The City held many meetings during the'fal of 1975 with the Waste Control Commission in an attempt to inform tY that there had been many changes in the planning requirements for tY City of Orono since the original design of the Orono -Long Lake interceptor and that the interceptor, as presently designed, was not consistent with the City Comprehensive Planning. The City did objec L to the design of the Orono -Long Lake interceptor at the public hear: d . the waste Control Commission agreed to re-eval held in November and Page 3 its design, amend the environmental assessment, and to offer severa new alternates to the existing engineering report from 1971. June 1976: The addendum to the engineering report for the Orono -L Lake interceptor was published showing four new alternate designs f the interceptor as well as three of the old designs from the 1971 report. Alternate A was supported by the City in that the routing was more conducive to serving the area of the City which was to be in the urban service area and four small areas along the route of the interceptor where prior development had created the need for sewer connection. The City objected to the flows projected by the addendum to the engineering report as well as the sewer serti area it- ` proposed to serve. August 1976: The Hetropolitan Council approved a staff report datee July 27, 1976, which approved the addendum to the engineering repos subject to the removal of Maple Plain, Independence Beach, Baker Park, and -the area of the proposed Vo -Tech School from the designat sewer service area. _ October 1976: The City of Orono adopted. a Comprehensive Sewer Plan which was consitent with its Comprehensive Land Use Plan as adopted in the fall of 1974. This plan clearly delineated the flow: required from the City of Orono through the year 2000 and also sho% the area of the City that was to be contained within the service area of the Orono -Long Lake interceptor. l November 10, 1976: The Metropolitan Waste Control Commission conducted a public hearing on the addendum to the engineering report for the Orono -Long Lake interceptor . • Page 4 The City found that alternate A in the addendum to the engineering report best exemplified the position of the City in being consistent with its Comprehensive Sewer Plan and its Comprehensive Land Use Plan The City did point out that the flows and the designated service area of the Orono -Long Lake -interceptor as shown in the adeendum to the engineering report, were not consistent with the Comprehensive Land Use Plan and the Comprehensive Sewer Plan of the City. It pointed ou; that the designated sewer service area was not consistent with the action taken by the Metropolitan Council in August 'of 1976 removing Maple Plain and certain areas within the City of Medina. November 26, 1976: The City received its preliminary Systems Statement as required under the mandatory Land Planning Act. The City's primary concern was the location of the M.U.S.A. line which was not shown to be consistent with the City's Comprehensive Land Use Plan. From November 26 through March 11, the City held many meetings with the Waste Control Commission staff and the Metropolitan Council staff reviewing and proposing changes in the design of the Orono -Long Lake interceptor, the City's Comprehensive Sewer Plan and the Metropolitan Council's System Statement. March 11, 1977: On this date, a meeting was held with the PCA, MWCC, Metropolitan Council, and the City staff. This meeting was a culmination of the negotiations that we had had since November of 197E and final agreement was reached on the following items: 1. The flows for the Orono -Long Lake interceptor would-be reduced to be consistent with the Orono Comprehensive Sewer Plan. C2. Designated sewer service area of the Orono -Long Lake interceptor would be reduced so that it would be consistent with the Orono Comprehensive Sewer Plan and the direction of the Metropolitan Council's action of August of 1976. Page 5 0. a 'J • 3. The Metropolitan Council's staff would recommend changes to the development framework moving the 2i.U.S.A. line so that it would be consistent with Orono's Comprehensive Land Use Plan. It was further agreed by all present that the Metropolitan Waste Control Commission would draft a new addendum to the engineering report for the Orono -Long Lake interceptor reflecting the reduction in flows and the designated sewer service area for final approval before the construction of the interceptor itself. The Metropolitan Council staff agreed that it would further amend its review of the Orono Comprehensive Sewer Plan and the Systems Statement reflecting the change and the designated sewer service area of the interceptor as well as the change in the M.U.S.A. line itself. April, 1977: The -City revised and resubmitted its October 1976 Comprehensi Sewer Plan in April, 1977. Changes were rased on requests of the I-mCC and Metro Council staff made during.the review process, and as a result ofour -final-agreement reached at the March 11, 1977 meeting. C important change in the redraft, made at the request of the MWCC and 2ietro Council staff, was to modify the scope of our plan, from a projection to the year 2000, to a projection to only 1990. All referenc beyond 1990 were removed with the understanding that the interceptor design was to only accommodate sewer flows from the sewer service area: as defined on the sewer service area Haps #2 & #8 contained in the Oroi Comprehensive Sewer Plan. Page 6 r`J .ay 11, 1977: The City received a revised Systems Statement from the Metropolitan Council staff. The City agreed with*the proposed Systems Statement with the exception that sewer service area 7 & 8 as delineated in the City's Comprehensive Sewer Plan to be contained in the rural service area rather than the urban service area. The City's position was that with this change for areas 7 & 8 that the proposed Systems Statement would then be consistent with the agreemen reached on riarch 11, 1977. The City, again, had several meetings with the staff of the Metropolitan Waste Control Commission and the Metropolitan Council discussing the exact positioning of the M:U.S.A. line. June 15, 197.7: The City received a copy of the Metropolitan Council's 60 staff review dated June 13, 1977, of the -City's - Comprehensive Sewer Plan. The review recommended moving the M.U.S.A. line as well as the designated sewer service area of the Orono -Long Lake interceptor to be consistent with the City's comprehensive planning. The City felt that this review was im_complete agreement with our meeting of March 11 as well as being consistent with the City's Comprehensive Sewer Plan and its Comprehensive Land Use Plan. June 16, 1977: The Metropolitan Waste Control Commission drafted a mems to the Metropolitan Council objecting to changing the designated sewer service area of the Orono -Long Lake interceptor from what was originally designated as early as 1971. Even though the population projections for Orono had been reduced from in excess of 35,000 to approximately 11,000 and the interceptor had been redesigned to serve a much smaller area as well as much smaller flows, the Waste Y Page 7 Control Commission felt that the designated sewer service area should contain vast areas of Orono to which the interceptor would not be sized to serve. It seemed that the primary concern here was the payment of reserve capacity that was built into the Metro system based on earlier projections of 35,000 people from the City of Orono. June 23, 1977: The City received a drastically revised Systems Statemeni adopted without the knowledge of the City that removed the recom- mendation to change the designated sewer service area of the intercepi as well as any changes to. the M.U.S.A. line within Orono. This Systems Statement is totally unexceptable to the City and it negates all the negotiations that the City has held with the Metropolian ( • ' Council staff since 1974. June 24, 1977: A letter sent from the Metropolitan Council informing us that the physicial development committee has delayed action on our Comprehensive Sewer Plan review and rescheduling an appearance for some later date. This later date was further cancelled and -we heard nothing from Metropolitan Council until September of 1977. September 8, 1977: The City received Addendum 2 to the Engineering Report for the Orono -Long Lake interceptor. The addendum contained additior flows and a designated sewer service area the same as the original area established in 1971. This addendum even included flows and designated sewer service area that was removed by the Metropolitan Council itself in action in August of 1976. This addendum was not in accordance with the agreement reached on March 11, 1977. Page 8 September 9, 1977: The City received a letter from the Metropolitan Counc staff informing them that a new staff member had been assigned to the City and that he was enclosing a copy of the redrafted staff review of the City's Comprehensive Sewer Plan for our review. This staff recommendation completely changed the intent of the prior recom- mendation removing any reference to changing.the M.U.S.A. line or modifying the designated service area of the Orono -Long Lake intercep from the original designation from 1971. . October 20, 1977: The City in a letter to the Metropolitan Waste Control Commission strongly objects to the information contained in the Addendum 2 to the engineering report for the interceptor pointing ( out that this was not consistent with the Orono Comprehensive Land • Use Plan, the Orono Comprehensive Sewer Plan - - , or actions.;by the Metropolitan Council in August -of 1976'and finally our agreement reached on March 11, 1977- 'December 977..December 7, 1977: Received Addendum 3 to the engineering report for the Orono-hong Lake interceptor which reduced the flows -for the intercepto to be consistent with the City's Comprehensive Sewer Plan and the action taken in August 1976 by the Metropolitan Council. The City found that while the flows were consistent with the City's desire that the designated sewer service area had not been changed and was still the same as the designated sewer service area in 1971 .based on population projections of in excess of 35,000 people. Page 9 10 January 4, 1978: After the City objected again to Addendum 3, the City received a letter from the Metropolitan Waste Control Commission refusing to change the designated sewer service area even though some of the areas had officially been removed by the Metropolitan Council in August of 1976. January 10, 1978: The City again restated its position in objecting to the designated sewer service area of the Orono=Long*Lake interceptor as proposed in Addendum 3 to the engineering report. t • C1 w1 METROPOLITA.'?

Introduction On June 15, 1976, the Metropolitan Waste Control Commission (MWCC) submitted an Addendum. to e Prelimiaary Ea^ineerin^ Report for the Orono -Lona Lake Interce^tor. The recommended project consists " of c fcx2-ai-1`sq-3tem•that will phase out both the Orono and, Long Lake sewage treatment plants and connect to a metropolitan interceptor in Wayzata; sewage will be treated at the MWCC Blue Lake plant. The recommended facility has changed substantially from the one recommended in the onginai report - and the N'WCC has requested Council review -of the change and comment on the status of the Council's approval of the original project concept in relation to the present project concept. This project rias beer. programmed for federal and state grants and so.the lvPCA is also awaiting the Courcil's attic,.. t II. Bac_ kzr_ curd The Orono -Long Lake Interceptor was first initiated -as project 71-13 in the MetopoLtan Sewer Board's 1971 Capital Improvement Program and was approved 'in concept by the Metropolitan Council. The pnrci- pal reason for the project was and remains the elimination of effluent dischar,ed to Lake hiin:�etonl:a - by the local sewage treatment plants at Orono and Long Lake. The completion of this project will leave one source discharging to the lake, namely the Maple Plain plant which discharges to Pointers Creek which in turn discharges into Lake Minnetonka In early 1973 the M1NCC completed a engineering report on the capacity,P preliminary type -and route of the interceptor which recommended Alternate 1, a gravity facility having the lowest annual costa Other alternates investigated had lower initial construc- - • tion costs but were all or nearly all forcemain systems and provided for more limited amount of local service " ..�';;.•` than the gravity facility. OnApril:19, 1974, the'Council adopted the following two recon merdations: i. That the Sewer Board construct .an"interceptor sewer for Orono and Long Lake and discontinue the operation of the :Orono and Long Lake Sewage Treatment Plants and that Alternate No. 1 of trams Preliminary Engineering Report for interceptor service be provided in the place of these. two sewage treatment" plants. -Alternate No. i calls' -for gravity interceptors throughOroro and ung L- h e ane a ,pu.^:pirg station oral forcemain through Wayzata to the iffayzata interceptor. 2- 'That interim sewage flow capacity for Maple Plain and Lake Independence area be provided _Jr. the Orono -Long Lake Interceptor until the year. 2000. J. 3. That theproject be recommended for approval rot federal and state grant application. The plats and specifications 'forthe Orono -Long Lake project were approved by the Council on June 27, 1974, Finally, on September 25, 1975, the Metropolitan Council adopted the Waste Management Policy Plan which included the Orono -Long Lake project as an approved system improvement ,)sroject recommended for construction- in '1976. . However, despite the fact that the ;Orono -Lon; Lake project has received Council approval and tivzs certified for federal and state grants for planning and construction, the project has not progressed to the constructior. stage.. When the ,h-1WCC completed -its plans and specifications for the facility _.. and th•_ right :)f way needed it requested approval .r:;m the of€ected units of ;o*ierrn+ent, rarrely the cities of Orcnp and Long Laka.. Praviously, the nvo communities ••had•expressed their approvol.of ' Alternate 1 through letters and -resolutions urging action on the Environmental Assessment of the facility. However,'ir: December 1975 as part of the public hearing held to meet federal requirements, the city of Orono requested a re-evaluation of the project -on the basis of their recently adopted comprehensive land use plan. The city felt the gravity facility was no longer consistent with the• community's goals for environmental quality and controlled growth.. The city was concerned that a gravity facility would unduly facilitate trunk connections contraryto local growth policy and be less cost-effective, that resultant excessive urbanizatianwodld increase stormwater runoff and require a higher level of municipal services, and that'the impact of both construction of the ". and urbanization upon the wetlands prevalent in the city's-area'would be'negative. In response to these concerns, the 1`fWCC submitted an amended environmental assessment and subseq;rertiy the addendum to.the preliminary engineeringvepor: which is under review at this . time. 1 III.

Interceptor service for Maple Plain, Independence Beach, and Medina is not shown. Rather, the Waste M✓ianage- ment Policy Plan includes one study on the various options for serving the Maple Plain area now shown as a rural town center; no study has been scheduled on the possibility of rrbviding metro- politan interceptor service from Medina to the Orono -Long Lake facility. Although the Addendum does include future flow calculations for the Maple Plain area and the Vo -Tech school and the Medina Morningside area, these added flows would not require a larger forcemain facility than does service to just Orono and Long Lake. Similarly, the capacity of the pump at tate lift station planned at the Long Lake site will be sufficient just for the•Long Lake -Hort ,ern Orono flow but a larger pump could be provided at the site if future facilities connect there. In forecasting future 50 -year flows for all communities, the Addendum uses the population forecasts of the Development Framework. B.'Cos-, ` Tha estimated cost of ;he recommended alternate is $3,600;383 which is close to the approved amount - n of $3,620,000 shown- the W;iste Management Policy.Plan.' This alternate will cost abouE •$500,000 .less to construct than the previously approved facility but will cost about $20,000 more annually to operate and maintain. The annual equivalent cost, incorporating both these factors and present wort:, . ;resoits.in nearly equal'costs: The 1976 MWCC Capital Budget carried the Orono-Long'Lake Interceptor as a previously authorized project with a total appropriation of'$4,258,600:This was commensurate with the original estimates but is now in excess of anticipated costs . V. Relationship to Local Plans `The Orono Comprehensive Plan was•revie.wed by the Council in October 1974 and discussion during the plan review revolved around Orono's expressed desire and intent to remain a low density residential community. 'Both the Council .and the city agreed on the need to protect the area's natural resources, especially lake Minnetonka, with strong development policies but, although the Orono plan was. revised to reflect ultimate accommodation, of 'growth projected by the Council, the effect of its pro posed'development ....Policies seems likely to delay the projected growth. Thus although the interceptor is designed to accommodate the growth projected by the Council,'the rate of utilization of the capacity may be slower depending upon _ ',:how.Orono regulates development and provides local sewer facilities. These issues will come before the ;Council during the -review of Orono's comprehensive plan and ,sewer policy plan.under the provisions of the =land Use Planning Act. r <- e Council has not reviewed the comprehensive plans of Long Lake; Maple Plain, or Medina . the comprehensive sewer - plan farMedlna he been submitted -but not reviewed by the Council; it does show _ both the Morningside subdivision and the proposed Vo -Tech school receiving service through a future 'metropolitan facility. As noted such proposed facility is not now planned for study. The questiori'of providing urban services to Medina as_part of the rural service area should and will be dealt with in the "Council's review of Medina's compreliensive-plan' and sewer policy plan. in the meantime, the pollution l problems in the Morningside area should be documented to'the MWCC,and if serious,access to the interceptor �'•" in Orono should be through Oto no's Local collection system if the two communities can work out an agreement ,�� � ;1.

The first concern is: what are the average daily flows that will be used to design the Orono -Long Lake interceptor. Secondly: what will be the sewer service area of this Metropolitan inter- ceptor, and, thirdly: where will the rural/urban service line be established. At our meeting on Friday morning, Aiarch 11, 1977, with the Metropolitan Council and the Metropolitan Waste Control Commission, these three concerns have been resolved to the satisfaction of Orono We are attaching the flows that were agreed upon to base the design of the Orono -Long Lake interceptor. We are also attaching to this letter a drawing showing the sewer service area resulting from the construction of the Orono -Long Lake interceptor as agreed upon at our meeting of last Friday. It is our understanding that these flows and sewer service area which are consistent with the Orono Comprehensive Sewer Plan will be interpreted by the Metropolitan Council so that the rural/urban service line shown in the dvelopment framework will also be consistent with the Orono Comprehensive Guide Plan. Mr. Douglas Nall ]arch 14, 1977 t .

Your CSP has been reviewed on the basis of the information that is necessary for preparing a satisfactory CSP. This information is as follows: 1. The CSP delineates the Urban and Rural Service Areas in the City. the CSP indicates that no extensions of sanitary sewers to serve existing and/or new development in Areas 7 and 8 of the Urban Service Area are intended prior to 1990 unless there is a documented pollution problem in the area. Sanitary sewers should be installed in these areas because; 1) the proposed Orono Interceptor traverses this area; 2) the MWCC-Rules and Regulations for the Metropolitan Disposal System require that connections be made to the sanitary sewer system within -two years of,its availability; and 3) this will avoid duplication of costs to install on-site sewage disposal systems which will later be phased out and connected to the sanitary sewer system. 2. -The CSP identifies a number of small developed areas of urban density which are located in the rural area and are serviced by on-site sewage disposal systems. It is stated that when pollution problems occur in these areas the City will study and recommend a solution to the -problem based on several alternates. The CSP identifies these alternate solutions and places the installation of sanitary sewers as the least likely alternate solution. The Commission believes that this alternate should be considered first in the solution to these problems. 3. Design information should include flow, capacity (or size and slope), time period and population served of the proposed sewer facilities. 4. The location, type and capacity of for public use, whether m-nicipally or identified includin their appropriate Elimination System ?NPDES) permit. In upgrading or terminating these systems are no such permits applicable, please information. all existing treatment facilities privately owned, should be National Pollution Discharge addition, a timetable for should be submitted. If there indicate this in the additional Mr. Walter Benson • Clerk -Administrator t City of Orono March 22, 1977 Page Two 5. Present sewered population and number of sewer connections together with a projected increase in sewer connections each by year for the next five years should be provided. 6. The 'type, quantity, and strength of wastewater from industrial .and institutional dischargers whose average daily flow exceeds �N 50,000 gpd or contains toxic wastes should be identified. If there are none, please indicate this. ^ 7. An ordinance adopting the Metropolitan Waste Control Commission's Rules and Regulations. 8. Minimum design standards for the control of inflow/infiltration into the sewer system should be a requirement in your standard specifications for sanitary sewer installation. 9. Ordinances controlling inflow/infiltration into the sewer system for new and existing facilities, including design, construction, and maintenance standards. 10. Ordinances controlling the development of flood plain, wetlands, steep slopes, drainage ways, etc. 11. Platting maps should be furnished which indicates the location of temporary and permanent on-site sewage disposal facilities. 12." An ordinance or ordinances should be provided which adopt. minimum standards for the design, location, installation, operation, maintenance and monitoring of on-site sewage disposal systems. The ordinance should include but not be limited to the definition, licensing requirements, permits, construction requirements, inspection, maintenance, penalties, etc. associated with implementing a program for on-site sewage disposal systems. 13. A monitoring procedure for on-site disposal systems should be furnished. This should include a system of records with dates of inspections, condition of facilities, maintenance program, disposal and pumping schedule of septage from such facilities systems. 14. Copies of all reports or tests conducted to determine if surface waters and groundwater show evidence of contamination from on-site system in areas -of clustered development. In addition, if any reports which study the effectiveness of on-site systems have been prepared, they should be furnished on this additional necessary information. • Mr. Walter Benson Clerk -Administrator City of Orono March 22, 1977 Page Three If you have any questions in regard to the information requested in this review, please write to us.

The report is scheduled to be discussed by the Council's Physical Development Committee on June 23 atV.:30 p.m. Orono is welcome to be represented at the meeting. You may be puzzled by the last paragraph of Recommendation 4 on page 4. It is necessary to permit the Waste Control Commission to provide sewer service to the lakeshore development. The Commission is prohibited by Council policy from providing service to development outside the Metropolitan Sewer Service Region. In most places the MSSR is conterminus with the MUSA, but there are a few exceptions. This will establish Orono as one of the exceptions and permit the developments to be sewered while remaining -a part of the Rural Service Area. Please call me if you have any questions.

Since the system statement is incompatible with the City's comprehensive plan, Orono has requested that it be changed. Concurrently, Orono has completed an interim comprehensive sever plan based on its 1974 proposes pensive development plan. Therefore, staff suggests that this CSP review tell Orono how the Council amend - to redefine the development MUSn Orono. The City's system statement can be written to reflect this proposed ment, andto the Framework afinale formally lsystem stamendedment later i 1 - Development year. This matter is urgent because the Council by is requiredissue Development Framework considerations will be explained in the next section of this review. Part IV will discuss waste management issues. _ 2 III. Development Framework Issues •The Development Framework map indicates that Orono is as urban fringe community (see Attachment A). The southern part of Orono around Lake Minnetonka is shown as "planned urbanization, 1975" although actually only the south- western part of the city has local sewer service. The northeastern section of the city around Long Lake and Wayzata is designated "additions, 1976-1980", and the northwest is shown as a "general rural use region". The northeast area is designated as an addition to the Urban Service Area because this was to have been part of the service area of the Orono -Long Lake interceptor as planned in 1974 when the land analysis for Develop- ment Framework was done. The chronology of events in Part II indicates that sewer facilities planning got ahead of land use planning in the Orono area, and was embodied in the Development Framework map. Now that local land use planning has been done, there is need to bring metropolitan plans into line with it if legiti- mate metropolitan interests and policies are not jeopardized by doing so. A principle of Development Framework is that the Metropolitan Urban Service Area shall contain sufficient land suitable for development to accommodate all urban development in the region through 1990 without creating undue land price inflation. The land analysis in the Framework, particularly Table 6 on page 32, indicates that there is ample land for development in the southwest Minneapolis sector even without the additional MUSA in Orono. An area in Chanhassen which will be added to the MUSA by 1980 will be sufficient to make up any deficit which might occur in the sector. Therefore, expanding the MUSA in Orono could be postponed until about 1990 without upsetting the principles of the Framework. Therefore, to make the Framework compatible with municipal planning, staff recommends that the Framework be amended by removing the addition to the MUSA in Orono. Orono's comprehensive plan, adopted'in 1974, contains policies favoring permanent low density development throughout the city, except in the urban area in the southwest corner. Orono has concluded from engineering studies that urbanization would lead to large amounts of polluting stormwater runoff which cannot all be fil- tered by the natural wetland system, and that development on two -acre lots is essential to preserve the quality of Lake Minnetonka. In 1974, the Council reviewed Orono's comprehensive plan and recommended the following: "That Orono revise its plan to include consideration of development beyond its first stage plan and commit itself to further investigation of controls and techniques to accommodate growth without undue environmental hazard." Since the MUSA will possibly have to continue to expand after 1990, and since Orono lies squarely in the path of growth in the I-394 corridor, the City is a logical place to expect urban growth after 1990. The City (&hould be aware of this and should also note that the staff's recommendation to alter the MUSA in Orono is of necessarily an endorsement of permanent low density development in the City nor of 2 -acre lot sizes. Additional investigation is needed of the relationship bete -en urban development in•.the Lake Minnetonka water- shed and the water quality of the lake. Orono's comprehensive plan submitted pursuant to the Metropolitan Land Planning Act should consider techniques for preserving the option of urban -density development sometime in Orono's future. IV. Waste Management Policy Plan An interim comprehensive sewer plan must include at a minimum: (1) a schedule of extensions of the local collection system over the next 3-5 years (including estimated number of connections and flow); (2) identi- fication of. an interim service boundary; (3) an indication of how unsevered areas will develop and what methods of waste disposal will be permitted; and (4) adoption of MWCC rules and regulations. The Orono CSP deals with all of these items. A. Local Collection System Extensions and Interim Service Area In addition to the main sewered portion of the City in the southwestern corner, there are several small pockets of development in Orono that are now sewered or shown in the CSP as potentially re- ceiving service in the future. All of these are in the rural service area. The largest pocket in- cludes the Hackberry Hills subdivision, the Orono Industrial Park, and Orono High School, all of which presently receive service through the Long Lake system. The CSP indicates that service to Hackberry Hills is temporary; it does not but should indicate the permanent service solution and when this will be programmed. Other severed areas lie adjacent to Wayzata on the east and presently receive service from Wayzata. The CSP states that there is capacity in the local sewers for more flow than presently generated but that the 2 -acre minimum lot size makes it unlikely that capacity will be used. The other area show for future sewer service is the Morningside area of Medina which was included in the approved interceptor service area on a limited basis. The City has stated its understanding that service to Medina must come through local lines and be negotiated between Medina, Orono and Long Lake. The City has also indicated by resolution its opposition to the proposed Vo - Tech school in Medina which was not approved by the Council for inclusion in the interceptor service area. The Orono CSP also identified 15 isolated areas of existing development presently served by on-site disposal systems. The CSP indicates that, as a general policy, the City will implement one of the following solutions when it determines there are pollution or sewage disposal problems in any of the 15 areas. (1) regulate future building to what can be satisfactorily handled by private, on-site disposal systems; L — 3 — • (2) strict enforcement of municipal ordinances pertaining to land development and sewage disposal on present as well as future building; (3) condemnation or redevelopment of problem properties where feasible; (4) installation of central sewers. The Council's and Commission's Alternative Waste Management Study will make recommendations next year for handling existing sewage disposal problems in rural areas. This study may indicate other alternatives available to Orono. - Seven (7) of these unsewered areas are within 1,000 feet of the shoreline of Lake Minnetonka and are adjacent to the Orono interceptor. The interceptor route was moved to this location so that these developments could be readily sewered. The seven developments are lettered B, C, D, E, F, G, and H on map 04 in Orono's CSP and are shown on Attachment B. The City and Council staff have agreed that four of the areas should be severed within three years and that the other three areas will be studied for potential sewer service. After considerable negotiation, the City has agreed to make the following commitments in the CSP: 1. The City will design and construct a local collection system for areas C -D and G -H within three years after the Orono interceptor is completed. Individual houses will be required to hook up within two years thereafter, in accordance with MWCC rules and regulations. 2. The City will monitor water quality and conduct studies on the economic and environmental impact of constructing local collection systems in areas B, E, and F. The findings and supporting data from these studies, together with recommendations, will be included in Orono's final CSP, which will be prepared pursuant to the requirements of the Metropolitan Land Planning Act. Each of these developments is located in the rural service area. Sewering them and assessing SAC charges requires an exception to the general Council policy of permitting connections and levying SAC only within the MUSA. Council staff believes that the public interest in improved lake water quality is best served by sewering these lakeshore developments and warrants an exception to the Council policy. The Council should therefore direct the MWCC to include areas B through H in the Metropolitan Sewer Service Region at the time these individual areas are to receive sewer service /• under the terms of Orono's approved CSP. ( B. On -Site Disposal Orono proposes to control on-site sewage disposal in the unsewered areas of the City. The City has regulations requiring permits to install on-site systems and has stated its intention to draft an ordinance regulating the design, construction, maintenance, and monitoring of systems in conformance with WPC -40 when it is promulgated or with its (the City's) own more stringent requirements. With the CSP as presented; such an ordinance will be the heart of the wastewater planning for the City. -rhe City has told staff that if will employ at`•least one full-time employee wil will be responsible for administering the City regulations from initial site evaluation through certification of completed construction to monitoring and maintenance; the City plans to finance this through permit fees. In short, Orono is pursuing a regulatory system that the Council has re- commended to other communities, and the City should be commended. As noted above, the implementation of such strict on-site system controls is an essential part of wastewatar planning; it is especially important in Orono where the buildable areas in the rural area are generally on heavy clay soils in which on-site systems have a high incidence of failure due to clogging or poor absorption. V. Conclusion The Orono CSP is here reviewed as an interim plan. It highlights critical Development Framework and waste management issues between the City and the Council. Based upon the redesign of the Orono -Long Lake interceptor, a redefining of the MUSA that is consistent with Framework and City policies is needed. Staff concludes that the City's proposal not to expand the MUSA in Orono before 1990 is consistent with the Framework analysis of urban land demand. However, permanent low density development in Orono is not necessarily consistent with Council policies. The City is advised to study this question in its comprehensive plan to be submitted pur- suant to the Land Planning Act. The City's waste management proposals for the sewer service area are in accordance with Council waste manage- ment policies. Proposals for the rural service area are incomplete. The on-site sewage disposal regulatory system is still being written; permanent sewer solutions to scattered developments next to Long Lake still must be negotiated between the cities, and the CSP needs to be amended to include the City's commitment to �• sewer and study scattered developments on Smith Bay and Browns Bay (areas B through H). RECOMMENDATIONS 1. The Metropolitan Urban Service Area within Orono should be amended as shown on Attachment C. Orono's system statement should be changed to advise the City of this recommended amendment to Development Framework. - 4 - f Before submitting its comprehensive plan for review pursuant to the Land Planning Act, Orono should re- evaluate its rural development policy by documenting: A. Potential pollution to Lake Minnetonka from alternate development densities and techniques; b. Potential impact of I-394 and post -1990 development pressures on Orono's rural area. 3. Orono's CSP should indicate specifically how the development served by the Long Lake local collection system will be served on a permanent basis. 4. Orono's CSP should be amended to provide for the following actions by the City: collection system for areas C -D nd G -H th ee a, afteri ithe Oronoeinttnerceptornisrcompleted. Individual houses and businesses awill bewrequired ryears and to hook up within two years thereafter, in accordance with MWCC rules and regulations. b. The City will monitor water quality and conduct studies oonndthe eccoonohe fic and environmentalnd i data are -as constructing local collection systems in B, E, from these studies, together with recommendations, will be included in Orono's final CSP prepared pursuant to the Metropolitan Land Planning Act. When the Waste Control Commission revises the Metropolitan Sewer Service Region (MSSR) to be the same as the MUSA, the individual lakeshore developments approved for sewer service shall be included in the MSSR for purposes of the Commission's cost allocation system, even though they are not in the MUSA. The Council's Waste Management Policy Plan should be amended accordingly. 5. The City is commended for the direction it is taking in the regulation of on-site disposal systems and should submit its revised regulations to the Council for review. 6. The City should adopt MWCC Rules and Regulations as part of its CSP- ( • /khf C7 - _ - Attachment A Uiban Service Area I LINWOOD :.._Fully Developed Area "" "T"" t I lull's OAR GJIOY[ ----� Planned Urbanization 1975 �" --- Additions 1976-1980 w t ANOKA CO.

This plan has affected the design flows for the Metropolitan Interceptor facilities. Exhibit A is a revision of Table 10 from the Preliminary Report Addendum. Flows from Orono have been revised to reflect less urbanization and sewering as planned. by Orono and shown in their comprehensive sewer plan. The table breaks the flows down by pumping stations to which the flows are contributed. The total average flows for 1995 from the revised table are as follows: Station Average Daily Flow cfs Orono Metro 1.65 Long Lake Metro 1.42 Orono Municipal '09 For the Metropolitan pumping stations, the design flows are as follows: Average Daily Flow Peak Factor Peak Flow Orono' 1.65 cfs 1.07 mgd 3.3 2450 gpm Long Lake* 1.42 cf s .92 mgd 3.4 2200 gpm -1- 0 ris 0 CA m C < m CL o n rWo _ ►v o a w PI w n� 0 00 00 bEl 0 r, 0 o 0 o m r 0w� oo W o 0 r O 00 m G F 7r p g cp cn r • t-4 to rt rl n w o Al m � w n w O r � 0 ris 0 CA m C < m CL a r rr m n w rt m m a Cl) Hb� a1 t-4 d lTJ F-� n o O H :3 n W rt M m H F4 C G to rr m FA- a 00 a rj m w 0, o n rWo wm0" . w rt � m r 0w� oo W o eo r wm t-4 to cn Al m � n w U) m n 7d < m ►� N ti -m IW V 1n0OOO a%Ot) :1 m w. w w r a n n C') � w r G a m IC) C) � A m m w r000ON OO W r n w w r r V VLn r *d ISD ON 00001, 000 W n r r� 03 m co ow o w rt 00000 0000 a a H w n o In o. 0% K rr ILn %D O r r r m w o+ rOoO%0 0%0w w r m N O O OOO OOr mC w r N 0 O r W w m V \O �DOtoLnW H C7 00 p o Q0m la 0 r In O W VO O N W \� %O In cn O O O 0 A Cl O O V O V O O O N FL fA n ht fA W O O O O O O O O r r HO V O VONNr Orin O R \p �D O Ln N OD V N W O N 11) r a e 00 a r rr m n w rt m m a Cl) Hb� a1 t-4 d lTJ F-� n o O H :3 n W rt M m H F4 C G to rr m FA- a 00 a rj m w 0, • The flows represent a population equivalent in 1995 of approximately 9,300 for Orono. This includes schools, commercial, industrial and.residential use. The ultimate population of Orono with the present zoning code is 13,870. Ito changes in flows other than Orono's have been made. Based on the pipe to be installed, there cannot be a large increase in pumping capacity from the Orono or Long Lake facilities. PUMPING STATIONS Station curves were prepared for the Orono and Long Lake • pumping stations based on 16" lines from each station and a 20" forcemain after the lines come together (Exhibits B and C). Because the Orono station curve with a 16" forcemain rapidly increases in bead loss with increasing pumping capability and the Orono pumps would operate almost at shutoff of the Long Lake station it was. determined that the Orono forcemain should be 18". Exhibit D is a station curve using 18" forcemain from Orono to the 20" combined line. This will provide the Metropolitan Waste Control Commission with a much more satisfactory operation for both the Orono and Long Lake stations. Exhibit E is a head loss curve for the 20 inch forcemain from the confluence of the Orono and Long Lake branches to the Wayzata pumping station. -3- In order to determine the pumping station conditions for the Orono Station it is necessary to add the head losses shown in Exhibit E to the 18" forcemain line from Orono (Exhibit D) to get the system curve when Orono alone is operating (Orono 18" FM + 20" FM curve of Exhibit D). To determine the pumping condition when both stations operate the head loss at 4600 gpm in the 20" line must be added to the Orono head loss in the 18" line at 2400 gallons per minute. Similar determinations are made for Long Lake (Exhibit C). The pu��.p design conditions for the stations are then based on 2200 gpm from the Long Lake Station and 2400 gpm from the • Orono station. The head loss through the 20" line is 44 feet at 4600 gpm. The total dynamic head for each station for pump design is then: Orono Long Lake Flow 2400 gpm 2200 gpm Static Head 36' 54' Branch Loss 30' 18' 20" F.M. Loss 44' 44' Total Dynamic Head 110' 116' As can be seen on the curves, the pumps selected fit the design condition very closely. With either station operating_ by itself with one pump running, approximately 2800 gpm will be pumped. If both pumps operate at either station approximately -4- • 3400 gpm will be pumped. (• Since one pump is provided as standby, it is not expected to operate two pumps at a time except for testing and eventually when the stations approach design flows.

Box 66 Crystal Bay, Minnesota 55323 Subject: Orono - Long,Lake Interceptor Gentlemen: LZ-) L ! � .i Scr i4u ��-AGF �0;= ►i :`-:'_� _� The decision that an 18" force main is required for the Orono line was based on hydraulic problems in operating two pumping stations that discharge into the same line. There is no greater capacity for Orono designed into the 18" nipe. When detailed design of the pumping stations was done, it became apparent that the Orono station operating with a 16" forcemain could cause the Long Lake station to lose the capability of u_umping its design flow. The 18" forcemain allows a selection of pumps which are essentially the same for both stations. This means operating conditions will be such that the overall system will act like a single pumping station with two pumps and 100% standby. The hydraulics of a system which includes two pumping stations with long force mains discharging to a single force main is very complex. These operating problems were not analyzed in the preliminary design phase of this project. An added benefit of the 18" forcemair- is that, instead of 125 or 150 horsepower motors that would be required for each of the Orono pumps with the 16 line, 100 horsepower motors can be used. This results in a substantial energy saving. Even with the 18" forcemain the Orono station will be unable to handle more then the flows projected in the report and approved by Orono. 12805 OLSON MEMORIAL HIGHWAY, MINNEAPOLIS, MINNESOTA 55441 TELEPHONE 1612) 559-3700 22 NORTH MAIN STREET.

During the process of this review, several questions have arisen which the City would like to have answered. The Addendum #2 apparently is not consistent with the agreement reached at a meeting with the P.C.A., Metropolitan Council, Metropolitan Waste Control Commission, and the City of Orono on March 11, 1977. I am enclosing a copy of our confirming letter to that meeting showing the City's three concerns with the Addendum #1 to the Preliminary Engineering Report that was dated February, 1977. The flows as shown in Addendum #2 do not correspond. -to the flows as agreed to in our meeting of March 11, 1977. I understand that these flows are being revised downward and we are expecting a revised Addendum #2 for our review. The City•is.-unclear as to what the proposed sewer service area will be for the interceptor as described.in Addendum #2. I am also enclosing the map of the agreed on sewer service area at our meeting on March 11, 1977. It was our understanding that this map would be adopted as the official sewer service area map together with the reduced flows in Addendum #2 to the engineering report. Could you please advise us as to the present status of the revised Addendum #2 and approximately when the City should receive a copy for its review. The City would also like to know what sewer service area map will be included with the reviewed Addendum #2. Mr. Bernard October 20, Page 2 J.

The revised addendum will show a reduced flow to the Long Lake Lift Station to conform with the Metropolitan Council's direction to exclude Maple Plain, the Independence Beach area of Medina and Morris D. Baker Park Reserve from the designated service area for this facility. We anticipate the revised addendum will be available for distribution in approximately one week. The service area for this facility was defined by the Metropolitan Council in their August 12, 1976 action, approving the Addendum to the Preliminary Engineering Report. This facility will have a design life of 20 years. Therefore, the facility service area contains that land area which could develop, or portions of which may require sewer service between 1990 and 2000. The Commission recognizes the local government's responsibility to define an interim sewer service area, applicable until 1990, in a comprehensive sewer plan -prepared in accordance with the Waste Management Policy Plan. This interim sewer service would not necessarily correspond to the facility design service area due to the difference in the time periods.

The flows from the City of Maple Plain and the Vo -Tech area, Independence Beach area, and Baker Park in the City of Medina have been deleted from the contributing areas of the Long Lake pumping station.. The design year is revised to the year 2000 since regulatory agency requirements are that a minimum twenty year design period be used. Delays in the completion of the project require that the design year be extended. The year 2000 is chosen because the system cannot be constructed and operational before 1979. A small increase in Long Lake flows is projected due to further development and increased population in Long Lake in the years 1995 to 2000. The increases are in keeping with the population projections shown in the first Addendum to the Report.

We also are in receipt of the revised engineering specifications and drawings which are being reviewed by the City at this time. It would appear from preliminary review of the Addendum #3 that the flows are now consistent with the agreement reached during our meeting of lurch 11, 1977, with the PCA, Metropolitan Council, and Metropolitan Waste Control Commission. Before our review of the proposed interceptor.can be completed, we must address the apparent inconsistency with the sewer service area proposed by the Metropolitan Waste Control Commission for this interceptor within the City of Orono. The proposed sewer service area as shown -for Alternate A in the Addendum to the Preliminary Engineerinc_ Report is in conflict with the City of Orono's Comprehensive Land Use Plan, and Comprehensive Sewer Plan_ Because of this apparent conflict, we have been unable fo.respond to the Systems Statement as prepared by the Metropolitan Council. We have requested that the public hearing process be kept open for the Systems Statement until such time as the Orono -Long -Lake* interceptor has been finalized and complete -agreement has been reached on its design and the sewer service area that it will serve. (• ,r Mr. Bernard J. Harrington - December 13, 1977 Page 2 • Bernie, I have talked to you several times on the telephone on this matter; the City feels strongly that it is imparative that we address this matter of the sever service area soon, and for that reason, I, again, request that the sewer service area be changed in accordance with the agreement that was reached at our meeting of March 11, 1977. The City's Comprehensive Land Use Plan does not project any flows to the Orono -Long Lake interceptor other than those projected in the Comprehensive Sewer Plan from sewer service areas one through eight to the year 2000. The City has instituted policies and ordinances to insure that any development occurring in the City of Orono through the year 2000, outside of the sewer service areas one through eight, will be served by on-site septic systems and not require municipal sewage collection systems. It is, therefore, imparative that the sewer service map for the Orono -Long Lake interceptor be consistent with City planning. The City would be pleased to meet with you at any convenient time to discuss this matter. Thank you for your cooperation in this matter. 1 YIU3* tI:a1J, • Brad Van Ne Orono Havor cc: Representative Robert L.

It is our understanding that you now concur with the provisions of Addendum No. 3 to the Preliminary Engineering Report for the subject project as stated in your letter. The Commission is proceding to obtain the necessary approvals and permits for the subject project based on the technical aspects provided in Addendum No. 3 to the Preliminary Engineering Report. Your letter also indicates a concern regarding an apparent inconsistency between the sewer service area proposed for the interceptor and that area shown in the preliminary Orono Comprehensive Land Use and Sewer Plan. The Commission acknowledges that this difference in sewer service areas results from the development of two time stages of projected sewer - needs. The sewer service area proposed for the interceptor is established consistent with the year 2000 needs and the area approved by the Metro- politan Council on August 12, 1976. It is through the process of comprehensive sewer planning that staged interim sewer service areas should be expressed. Therefore, the City should complete the preparation of a Comprehensive Land Use and Sewer Plan in accordance with the provisions of the Metropolitan Land Planning Act and the Waste Management Policy Plan. The comprehensive sewer plan should designate the areas where sewer service will be provided and indicate the, time*schedule for providing service where metropolitan facilities are available.

Harrington Metropolitan Waste Control Commission 350 Metro Square Building 7th & Robert Streets St. Paul, Minnesota 55101 Subject: Orono -Long Lake Interceptor Dear Mr. Harrington: The City of Orono is in receipt of your letter of January 4, 1978 regarding the Orono -Long Lake interceptor project. After reviewing your letter, it is apparent that we should restate some of the facts as they relate to the City's position on the Orono -Long Lake interceptor in the following areas: 1. The City does not concur with the provisions of the Engineering Report in as much as the sewer service area is incorrectly shown for the Orono -Long Lake interceptor. The sewer service area map contained in the Engineering Report still shows Maple Plain, Independence Beach area in Medina, Morris T. Baker Park Reserve, and the Vo -Tech School site as part of the Orono -Long Lake interceptor designated service area. These four areas were specifically excluded from the sewer service area by action of the Metropolitan Council in August of 1976. 2. In October of 1976, the City did complete its Comprehensive Sewer Plan and presented it to the Metropolitan Waste Control Commission for your review and approval. Fourteen months have now elapsed and vet the Metropolitan Waste Control Commission has not made a final determination on our Comprehensive Sewer Plan. 3. We have had many meetings with the Metropolitan Waste Control Commission staff together with the Metropolitan Council staff in regard to requested modifications to our plan. These changes to the Comprehensive Plan were culminated in an agreement reached in March of 1977 which resulted in our amended plan dated April of 1977. Nine months have elapsed since this amended plan has been mr. Bernard J. Iiarrington • January 10, 1978 Page 2 presented to the Iletropolitan Waste Control Commission for your approval and yet no action has been taken. 4. The original Comprehensive Sewer Plan prepared by Orono in October of 1976 projected the City's sewer needs through the year 2000. The Iletropolitan Waste Control Commission staff objected to any reference being made in our Comprehensive Sewer Plan beyond the year 1990 and we were requested by the Metropolitan Council staff to so amend our plan as to remove any references beyond the year 1990. The Orono -Long Lake interceptor is presently designed to provide capacity as projected by the City through the year 2000 for only that part of the City lying in sewer service areas 1 through 8. The balance of the City, which you are including in your sewer service area map, is not included in a projected sewer area until at least after the year 2000. The inclusion of rural Orono into the sewer service area of the Orono - Long Lake interceptor by the Waste Control Commission is in serious (• conflict with the City's established land use planning for that area. The results of this conflict mean that these lands will be included in the urban service area by the. Metropolitan Council rather than the rural service area as requested by the City's comprehensive planning. The City views this as a major obstacle preventing the statutory right of the City to plan its land use patterns within the structure of its comprehensive land use planning. 4p The City has requested several times in the past -four months to have a meeting with you to resolve this issue. The City is willing to negotiate this matter in order to alleviate any problems that the Waste Control Commission may have with•reserve.capacity, originally programmed for Orono, or any other concerns that the Waste Control Commission may have. We feel that it is important that these negotiations be culminated at an early time so there will be no additional delays in the construction of the Orono -Long Lake intercept( Until the sewer service area of the Orono -Long Lake interceptor has been finally determined and acceptable to the City, we are unable to respond to the System Statement prepared by the Metropolitan Council dated June 23, 1977. Because of this inconsistency of the sewer servi area, the public hearing process allowing the City to object to the System Statement has been kept open until this issue has been resolved. This is yet another reason why this inconsistency must be resolved at an early date. fir, Bernard J. Harrington January f6, 1978 Page 3 As you know, the Orono -Long Lake interceptor was originally planned in 1971 and the sewer service area was established at that time. Since that time, the population projections for the City of Orono have drastically been reduced requiring changes in the City's comprehensive land use planning, a complete redesign of the inter- ceptor itself, including rerouting of the interceptor to be consistent with the City's planning. These changes that have occurred since 1971 require that the original sewer service area for this interceptor also be changed so that it is consistent with the design of the interceptor and the City's comprehensive planning. The City would be pleased to meet with you at any convenient time you desire to discuss this inconsistency and negotiate a satisfactory alternative. The City has employed the firm of Bonestroo, Rosene, Anderlik and Associates to review the design of the Orono -Long Lake interceptor. At the conclusion of their report, we will respond with our comments to the information contained in the Engineering Report for this project.

Until our Comprehensive Sewer Plan has been approved and the sewer service area of the Orono - Long Lake interceptor is adjusted to be consistent with our Comprehensive Sewer Plan, it is impossible for the City to respond to the accuracy of the Systems Statement approved by the Metropolitan Council on June 23, 1977_ The City requested an extension to the 60 day appeal period as provided in the Metropolitan Land Planning Act. The City is presently at a standstill in the process of restating our Comprehensive Land Use Plan adopted in 1974 until such time as these issues are resolved. We would be pleased to meet with you or your staff at any convenient time to discuss these inconsistencies in our planning process. • Mr. John Boland • January 10, 197£3 .

The issue at hand is whether or not the City can successfully negotiate with the Metropolitan Council to define where the 2s U S A line shall pass through its own area. We have attempted in good faith for many months and just cannot seem to reach an agreement by negotiation. I think the most distressing thing to me is that on March 11, 1977, we did reach an agreement that was satisfactory to the. City and that after that date, the proposed Systems Statement and the review of our. Comprehensive Sewer Plan were amended in accordance with this agreement. On June 16, from an objection from Mr.. Doughert. of the Waste Control Commission, all of this was changed, including the staff member that we had been working with for the past nine months. ' Since that time, we just have not gotten .any cooperation or any information as to what is going on and why. Our Systems Statement was summarily issued on June 23, not in accordance with our negotiations, the review of our Comprehensive Sewer Plan was modified in September to a position that the City could never agree to, and even the design of the' -Orono -Long Lake, interceptor shows a designated sewer service area that prevents the M.U.S.A. line from being adjusted to be consistent with the City's Comprehensive Planning. Representative Robert L. Searles January 16, 1978 Page 2 • I hope that the Metropolitan Council will bring this issue to a head soon by taking some action in this matter. This would allow the City to state its case before them, and if we lose, to take whatever appropriate action we may find possible. I still feel that negotiations between the City and the Metropolitan Council is extremely important and hope that somebody will be able to resolve this inconsistency without the need for a lengthy and expensive review procedures at a higher level. If I can be of any further assistance in this matter, please feel free to contact me at your earliest convenience.

Karl Burandt, of the Metropolitan Council staff, was also present and informed us that he was drafting a staff review of the Orono -Long Lake interceptor to be presented to the Physical Development Committee in the near future.. During the course of the meeting, it became clear that the intercepto pipe itself had some additional hydraulic capicity that would allow_ for future expansion of the sewer service area within the City of - Orono. The pump stations that are presently designed for the interceptor will only handle the flows projected*by the City from that part of our City which is presently sewered and which we intend. to include in the urbran'service area, but the pipe itself could handle additional flows if larger pumps were installed at a later date. As you know, on June 13 of 1977, Sandy Dean of the Metropolit& Council staff recommended to the Physical Development Committee that the MUSA line within Orono be moved in accordance with our Comprehens. Planning but that recommendation has been withdrawn because of the objections of Mr. Dougherty of the Waste Control Commission in that the MUSA line must be consistent with the Metropolitan sewer service area. The City's position has always been that the Orono -Long Lake intercep. was brought in to Orono for purposes of removing the effluent from :*the Orono and Long Lake sewer plants and not to provide a catalyst forcing urbanization of.rural Orono to a level beyond which Lake Minnetonka could tolerate from the standpoint of higher phosphorus content of the storm water runoff. Representative Robert L. Searles February 6, 1978 Page 2 Before the City can endorse the Orono -Long Lake interceptor as presently designed, the following question- must be answered by the ?Metropolitan Council and Metropolitan 17aste Control Commission in a method that the City can rely on: Can Orono, in restating its Comprehensive Land Use Plan, locate the MUSA line in such a way that the unseiaered portion of the City will be in the rural service area, even though the proposed Orono -Long Lake interceptor pipe itself, may have additional hydraulic capicity beyond the pumping stations presently designed to serve only that portion of Orono which will lie within the urban service area and which is presently sewered? As you know, Bob, the City submitted its Comprehensive Sewer Plan in October of 1976 and .negotiated'with the Metropolitan Council until finally reaching an agreement in March of 1977, which resultec in an acceptable Systems Statement and staff recommendation of the Comprehensive Sewer Plan in June of 1977. Since that time, the City has received no assurances from the Metropolitan Council staff �• that we will be able to locate the MUSA line in accordance with our Comprehensive Plan adopted in 1974. It seems to us that before we go to. any expense of restating our Comprehensive Plan in accordar with the Mandatory Land Planning Act,that our Comprehensive Sewer Plan should be approved and a meaningful answer to the question stated above .should be given by the Metropolitan Council. We feel - strongly that the ground rules should be agreed on before the Orono - Long Lake interceptor is -constructed so that we don't find out that tYie.game is over once the interceptor is constructed and that the fact that the interceptor -is in the ground dictates that all of rural Orono must be in the urban service area of the Metropolitan area.

Orono Comprehensive Sewer Plan. Orono submitted its Comprehensive Sewer Plan dated October 1976, and after nine months of negotiations with the Metropolitan Council staff, agreement was finally reached and our redrafted Comprehensive Sewer Plan dated April 1977, was submitted. Copies of this Phase .1 of our Comprehensive Sewer Plan were presented to the Metropolitan Waste Control Commission, Metropolitan Council, and the Pollution Control Agency. 'We- have had several meetings concerning the redrafted Plan, but as yet, there has been -no approval or final determination on its acceptance.

In order to restate our Comprehensive Land Use Plan that was .approved in 1974, under the conditions set forth in the Mandatory Land Planning Act, Orono must have some commitment as to the general accept ance by the Metropolitan Council of its position of the I4USA Line within our City. On February 2, 1978, we attended a meeting at the IIV?CC to discuss the Orono -Long Lake inter- ceptor. The City agreed to revise the location of the MUSA Line within Orono to satisfy objections raised by the MWCC staff, which was done and submitted on February 7, 1978. • • Mr. John February Page 2 Boland 16, 1978 As a result of that meeting, we have.requested the Metro- politan Council staff and the Metropolitan Waste Control Commission staff to give, in writing, any objections that they would have to the location of this MUSA Line within Orono. To date, we have not received any reply to these questions. 3. Revised Systems Statement- In December, you provided us a copy with a revised Systems Statement showing a reduced flow and traffic projection for the City; on January 10, we requested,in writing,an explanation of how these figures were arrived at. To date, we have received no information pertaining to this revised Systems Statement. I point out that our 60 day appeal period is practically up and it is important that this information be provided to the City at the earliest possible time. 4. Sewer Service Area of the Orono -Long Lake Interceptor. At our meeting of two weeks ago with the Waste Control Commissiol we learned, much to our surprise, that the Orono -Long Lake interceptor had additional capacities beyond the flows shown in Addendum 3 to the Engineering Report. The Waste Control Commission could not tell us what this additional capacity was, -but that they would give us that information together with the areas within Orono that it was intended to serve. To date, we have not received this information and -feel strongly that we must have this information before final approval is given to the Orono -Long Lake interceptor design_ We are enclosing copies of our letters requesting the information referred to.above which we have not received_ The City would like to have answers to these questions and a copy of the Metr6p.olitan Council's staff review of the Orono -Long Lake interceptor in sufficient time that we may review these documents prior to action by the Physical Development Committee.

The Commission has reviewed the proposed interim 1990 MUSA as shown on your Map 1, "Urban - Rural Service Area" submitted with your letter of February 6, 1978. Your plan has excluded the Wayzata Country Club and the Chevy -Chase Development, however, according to our knowledge these areas are already being provided sanitary sewer service through the City of Wayzata. With the inclusion of these two areas, the Commission has no objection to having the interim 1990 MUSA boundary established as shown on said map. The Commission uses the term interim 1990 MUSA boundary since the exact location of the line will not be established until after your Comprehensive Plan/Sewer Plan are prepared in accordance with the Metropolitan Land Planning Act. Please refer to our letter of March 22, 1977 regarding the information needed to update your preliminary comprehensive sewer plan to the current require- ments of a comprehensive plan. If it is your intention to have this preliminary comprehensive sewer plan reviewed and approved as an amendment to your original -Comprehensive Sewer Plan (approved on November 7, 1973), please submit an adopted revised plan which represents the City's current planning. You asked the question during our meeting as to what parameters were used in the design of the lift station and forcemain. The design of the lift stations and forcemains are based on the following: Current Desi4n - 20 Year Life Orono Station (one pump and,one standby pump) 2400 gpm peak or 1.07 mgd average 101 feet of total dynamic head 18" Forcemain velocity = 3 feet per second 20" Forcemain velocity = 4 feet per second Population Equivalent served by Lift Station 8500 Orono 600 Minnetonka Beach 500 Orono - Local Lift Station 350 METRO /OUARE BLDG. 7TH& ROBERTlTREETf /RInT PAUL mn 55101 612 222.8423 n Mr. Brad Van Nest, Mayor City of Orono • March 1, 1978 Page Two Long Lake Station (one pump and one standby pump) 1600 gpm peak or .65 mgd average 99 feet of total dynamic head 16" Forcemain velocity = 2.6 feet per second 20" Forcemain velocity = 4 feet per second Population Equivalent served by Lift Station 950 Orono 400 Medina -Morningside 4250 Long Lake The design of the pumps include consideration's for a 20 -year life base on current flows and population projections. We have used engineering practices and operating experience to size the pumps at 100 horsepower and to pump against approximately 100 feet of total dynamic head. We know from experience that pumps in excess of 100 horsepower and heads greater than 100 feet involve costly operation and maintenance. The forcemains are directly related to the pump sizing and are designed to minimize head loss and still provide adequate scouring velocity at the design flows. The total dynamic head of i::)oroximately 100 feet in the forcemain system is higher than average. The Commission owns and operates 59 lift stations in which one-third of the facilities have heads of 50 feet or less, one-third have heads between 50 and 90 feet and the remaining third are considered high head lift stations with heads greater than 90 feet. In the design of the lift stations, space has been allocated for the addition of a third pump. If it becomes necessary to install a third pump in the future to provide a two -pump system with one pump as standby the capacity of the Orono Station will be increased to 2800 gpm (about a 17 percent increase) and the Long Lake Station will be increased to 1900 gpm (about a 19 percent increase). The 16, 18 and 20 -inch forcemain system as proposed for the Orono -Long Lake Interceptor represent a higher head than normal pumping situation, but are considered to provide the most cost effective arrangement for the design needs. Enclosed is a map delineating the Orono -Long Lake Interceptor Service Area as defined by the Metropolitan Council in the approval of the Preliminary Engineering Report. • Mr. Brad Van Nest, Mayor City of Orono March 1, 1978 Page Three If you have any questions regarding this matter, please call.

The information contained in your letter will be submitted to the City Council of Orono at its next meeting for their discussion and action. I would like to take this opportunity to point out to you that the Orono Comprehensive Plan adopted in 1974 shows this area, for good reason, to be in the two acre zone of the rural service area=within the city -of Orono. There are inadequate roads servicing that general area and we do not have the necessary fire and police protection services -to allow for any denser development in this general area. Moreover, these lands in that general area are environmentally sensitive with steep slopes and marshes and any sort of dense development would be adverse to them in the quality of the surface water runoff. It is also•our understanding that Highway #12 is proposed to be extended through this general area and it does not make good sense to have a dense development in this area that would require the disruption of all of these people because of the extension of a State highway. This problem with the Neslund property demonstrates vividly the point the City of Orono has made to the Waste Control Commission many times in the past concerning the sewer service area of the Orono interceptor. The sewer service area of the Orono interceptor, as shown on a recent map provided by Mr. Harrington of your office, is totally inconsistent with the Orono Comprehensive Land Use Plan and the Orono Comprehensive Sewer Plan in that the sewer area encompasses all of rural Orono, which is not to receive sewer service for -at least the next twenty years. r1 U ;,s. Barbara L. Lul:ermann March 7', 1978 • Page 2 The purpose for the Orono interceptor was originally to move the effluent from the Orono sewage treatment plant, which was polluting Lake Minnetonka. The design of the interceptor went far beyond the original intent and actually, was intended to force urbanization of all of the City which would have a far greater polluting impact to Lake Minnetonka than the original purpose for the interceptor in the first place. The City has been unable to determine what the ultimate design capacity of the force main is and how much of the City of Orono it is intended to serve. We have asked these questions many times and, as yet, we have not received a satisfactory answer, in fact, it was only this past week that we received a map showing the sewer service area of the -Orono interceptor as I. presently designed. The City of Orono has always supported the original intent for the Orono interceptor but cannot support the present design of the interceptor if the sewer service area is to include all of rural Orono. I have taken the liberty to attach to this letter some documentation concerning the long history of the Orono -Long Lake interceptor and the many inconsistencies in its design. The City of Orono would like to cooperate with the Waste Control Commission to reach an agreeable compromise that would allow the construction of the Orono interceptor Isat the earliest possible date. We believe that this can be accomplished and are willing to work toward that end. I will be out of the City until March 22, but would be very pleased to meet with you any time after that* at vour convenience. Representative Robert L. Searles has meet with John Boland recently to discuss this problem and I think that we could reach an agreeable solution so that the 0 -ono interceptor could be constructed in a manner that would be consistent with the City of Orono's comprehensive planning.

Bernard J. Harrington Metropolitan Waste Control Commission 350 Metro Square Building 7th & Robert Streets St. Paul, Minnesota 55101 Dear Mr. Harrington: This letter is in response to your letter of March 1, 1978. We have instructed our City Engineer to make the modifications •to 11j.- 1,"Urban-Rural Service Area" of the Orono Comprehensive Sewer Plan dated April 1977 to include the Chevy Chase Sub- division, the Ferndale Green Subdivision, and the Wayzata -Country Club clubhouse within the urban service area of the City of Orono. lie are pleased that the Waste Control Commission will concur with this JIUSA line within the City of Orono as it is consistent with the Orono Comprehensive Land Use Plan and the Orono Comprehensive Sewer Plan which is presently before you for review and approval. As soon as the map has been amended and adopted by the City Council, we will submit • it for your review. There seems to be some misunderstanding as to the present status of the Orono Comprehensive Sewer Plan la that was 1977or1Theally sudmitted pensive in October of 1976 and amended inApril Sewer Plan for the City of Orono was transmitted to the Waste Control Commission, the Metropolitan Council, and the Minnesota Pollution Control Agency in April of 1977. This amended plan was submitted in response to the comments of your letter of P -larch 22, 1977 and the agreement reached with the Waste Control Commission staff at our meeting of March 11, 1977 with the PCA and the Metropolitan Council staff. This amended Comprehensive Sewer Plan meets the requirements for cisr Comprehensive Sewer Plan and has been before you for your revi`w and approval for the past ten months. The Citv of Orono is at ill in the process of restating its Comprehensive a complete standst Plan under the requirements of the Mandatory Land Planning Act until .. such time as our Comprehensive Sewer Plan is adopted by the Naste Control Commission and the location of the P1USA line within Orono is agreed to, the size of the Orono interceptor service area has been determined, and finally, an amendment to the Orono Systems Statement by the Metropolitan Council. Mr. Bernard J. Ilarrington - I4arch 7, 1978 Page 2 • The Orono Council feels that ten months is a sufficient amount of time for the Waste Control Commission to review a Comprehensive Plan that has been submitted for approval, particularly in light of the fact that the plan originally submitted in October of 1976 and for the next five-month period, the City negotitated with the Metropolitan Council staff and the Waste Control Commission staff to reach a final agreement on this plan in I -larch of 1977; the plan was then amended in April of 1977, and a favorable review% by the Metropolitan Council staff was drafted and submitted to the Physicial Development Committee in June of 1977. It was at this meeting that the Waste Control Commission objected to changing the 14USA line within Orono, which resulted in the review being tabled and no action has taken place since that time. The City respectfully requests that the Waste Control Commission continue the review process and grant us an approval within the very near future. During our meeting of February 2, 1978, it became clear to us that the Orono interceptor had additional capacity beyond that which was shown in the Orono Comprehensive Sewer Plan and in Addendum #3 of the Engineering Report. This was confirmed to us with a commitment that we would be told what _hat capacity was and what area within the City �. of Orono it was to serve. The information contained in your letter of March 1,1978, shows the average flows only for the lift stations • which do reflect information from our Comprehensive Sewer Plan and Addendum #3 to the Engineering Report. You have indicated that there - is approximately an additional -seventeen percent increase in the capacity of the interceptor in the event a third pump were to be installed at the lift station. We have submitted this information to our City Engineer for review and recommendation but it appears to me that you have not responded to our basic question of "is there any additional hydraulic capacity designed into the force main of the Orono interceptor?" If there is additional capacity beyond the -oresent lift station even with the addition of a third pump, the City would like to know what that additional capacity is and how you have arrived at the service area within the City of Orono that it is to serve. In looking at the sewer service area map provided with your letter of March 1, it becomes apparent that the Orono interceptor is designed to serve all of Orono, including that portion which is considered in the rural service area. Either you have designed the force main to serve rural Orono or the sewer service area map is incorrectly drawn including rural Orono, which is not to be within the sewer service area. The City of Orono must have answers to these questions before it can support the construction of the Orono interceptor. The City feels it is entitled to this information and it has repeatedly asked these questions which have not been adequately answered. I7r. Bernard J. I7arch 7, 1978 Page 3 • Harrington The City would like to remind you that the reason that the Orono interceptor was approved initially was to remove the effluent from the Orono sewage treatment plant, not to urbanize the entire City. Since the initial design of the interceptor, it becomes even more important to clarify the sewer service area because of the decline in the projected population of Orono and the apparent conflict between the sewer service area and the IIUSA line within the City of Orono. The City respectfully requests that the answers to these questions be submitted at the earliest possible date so that our City Engineer can review this information prior to the Metropolitan Council's final approval of the Orono -Long Lake interceptor plans and specifications. lie would be pleased to meet with -you to discuss'this.matter, if necessary, at your convenience.

It addresses the questions you raised in your letters to me, John Boland, and Karl Burandt dated February 6, 16 and 17. In regard first to the revised Metropolitan Urban Service Area map you included with your letters, Council staff estimates that the proposal would add about 600 acres of land in Orono to the existing area of service. The area on the map is adequate in size and location for planned urban development to 1990, insofar as staff is concerned. This opinion rests on several major assumptions, however. It assumes that the map establishes the proposed 1990 area of service and that local services will be staged within it by five-year increments. It also asusmes that other aspects of the City's comprehensive plan prepared pursuant to the Metropolitan band Plan- ning Act will be consistent with Council policy and plans. Three of the more important plan aspects are policies and implementation measures for maintaining the rural character of the rural service area, an ordinance governing on-site sewers, and plan compatibility with adjacent local governments. Another assump- tion is that other municipalities in the same sector as Orono will propose com- prehensive plans so that the cumulative amount of urban and rural service areas will be in scale with forecast growth for the sector as a whole. Preliminary indications from other municipalities in the sector, plus consideration of Orono's proposed 1990 MUSA, indicate this probably will not be a problem. It is impossible to say with absolute certainty at this time whether all of these assumptions are correct because adequate information from comprehensive plans will not be available until local governments have fulfilled the terms of the Land Planning Act. In regard to sewers, the 1990 sewer flow estimate recently sent to Orono was calculated as follows. A.sewered population of 6900 people in 1990 generating 83 gallons per person per day was assumed. This results in .57 million gallons An Agency Created to Coordinate the Planning and Development of the Twin Cities Metropolitan Area Comprising: Anoka County 0 Carver County 0 Dakota County 0 Hennepin County 0 Ramsey County 0 Scott County 0 Washington County D" Mayor Brad Van Nest Uj 98909 March 8 1978 13 1?78 Page Two r,!� Y11_LAG19 03 ORORQ •per day of domestic sewer flow. Orono's industrial flow in 1976 of .01 million gallons per day was added to the estimated 1990..domestic flow for the.total .58 million gallons per day. This is an optimistic estimate of the maximum flow from Orono that could be accommodated by the metropolitan sewer system in 1990. If the City produces less flow, then it will have unused reserve capacity available. If the City exceeds the 1990 flow, then there may be a problem accommodating the excess flow in the metro sewer system, and the Blue Lake Treatment Plant may need upgrading sooner than planned. In effect, the 1990 sewer flow estimate represents the maximum flow that the metro sewer system will be able to accommodate from Orono in 1990. A lesser flow is acceptable from a sewer planning standpoint, but a greater flow could be a problem which should be discussed with Council and Waste Control Commission staff as early in your planning process as possible. The plans and specifications for the Orono portions of the Orono -Long Lake In- terceptor are discussed in a letter dated March 1, from Bernie Harrington of the Waste Control Commission. It answers your questions about design capacities and service areas.- As reas. As you know, one of the purposes of the Land Planning Act is to establish local staged growth plans to 1990 consistent with regional needs, plans, and policies. Yet for economic and engineering reasons and to meet federal and state funding criteria, many metro facilities are designed for useful lives beyond 1990. Although the immediate task is to stage comprehensive plans to 1990, at some point it will t •be necessary to plan for local growth beyond then. Planning.beyond 1990 is not required by the Land Planning Act, but it is permissable. The Council and Waste Control Commission assume sewer flows after 1990 will come from beyond Orono's 1990 sewer area but within the area shown on the map accom- panying Mr. Harrington's letter. Areas of service and rates of usage depend on local determinations such as land use densities, local service timing and staging, and other similar factors established through local comprehensive -plans. The factors which determine sewer flows and service areas are established by each city as discretionary development controls. Thus, the metro sewer system is planned using assumptions about ultimate design flows and service areas, but its usage can be modified, staged, and controlled by local plans. Interceptor designs do not necessarily relate to treatment plant capacity, nor do they necessarily take into account other matters which affect actual available capacity. Metro systems statement sewer capacities should serve as the basic building block for local determinations, not interceptor design capacities. The Land Planning Act requires you to state the City's policies on matters contained in Orono's system statement so that the Council can evaluate the ability of the metro systems to provide the desired service and the effects of Orono's plans on others. Turning to travel forecasts, the attached figure shows the generalized process Council staff followed. The process uses a very complicated computer model which I cannot even attempt to explain here. When you need to get into the details of the model, please contact Steve Alderson (291-6337) of the transportation staff with your questions. What the model does in essence is convert demographic forecast data into a number of trips generated, and the trips are then assigned to the Council's planned 1990 L JU. F.-: Mayor Brad Van Nest " -tib ga L5 March 8, 1978 ) Page Three • transit and highway network. This enables the Council and--0de-:K5__to' -'sqate .Oi& use of each system element and to anticipate future bottlenecks and needed improve- ments. To do this, the Council has divided the Metropolitan Area into traffic assignment zones (TAZ). Orono has five as shown on the enclosed map. There are five especially important demographic variables used in the process: total households, total population, total employment, retail employment, and service, financial, insurance, and real estate employment. More than any other variables they dictate the gross magnitude of trips which are produced or attracted by a TAZ. Changes in any of these five variables will measurably affect trip making characteristics of a zone, whereas large variations in other demographic variables will have only a marginal effect. Thus, when the Council revised its forecasts of total households, population, and employment last December, three of the five critical variables were changed and resulted in the revised traffic fore- casts for your system statement. The attached copies of computer printouts show the demographic variables used to make the traffic estimate sent in Orono's original system statement. They are broken down by TAZ, and a decoding sheet is also included. Except for revised figures for total households, population, and employment the variables are the same for the updated 1990 traffic estimate of 44,000 person trips per day which you recently received. The 44,000 figure assumes the forecasts of total households, population, and employment enclosed with the December 28, 1977 letter, i.e., the most current forecasts. At the present time Council transportation staff are re- evaluating all the original assumptions in light of the new forecasts to determine . if other variables should also be changed. If after reviewing this information you feel the City can provide more accurate data, please contact Steve immediately so it can be considered. In conclusion, this information should allow us to clear the books on several items currently pending between the City and the Metropolitan Council. First, -I recommend that the Council review the Waste Control Commission's plans and speci- fications for the Orono -Long Lake Interceptor as -soon as possible. We would like to present a report to the Physical Development Committee on March 23. We would mail it to you and the Committee on March 17. Second, I recommend the City amend the interim comprehensive sewer plan previously submitted for Waste Control Commission review to include the revised 1990 urban service area map which you just sent us. Shortly thereafter the interim CSP review can be completed. I emphasize interim CSP because the immediate objective is to plan service for the three to five year period following construction of the Orono -Long Lake Interceptor, leaving finalization of plans for the period to 1990 for the comprehensive•plau Orono is preparing pursuant to the Land Planning Act. Third, if the City wants to request a hearing on its Metropolitan system statement, you should file a request according to the Planning Act by March 23. Since the Planning Act provides no mechanism for extending the local system statement review period, it is imperative for the City to make its decision by then. I believe that all the important infor- mation on sewer flows, traffic generation, and growth forecasts has already been sent to Orono and included in the system statement. If, however, there is a need to amend metro system plans as a result of the above Council reviews, appro- priate system plan amendments will be proposed. Mayor Brad Van Nest March 8, 1978 r Page Four •Though lengthy, this letter should resolve a lot of questions and get us moving again. I appreciate the time you and the other Orono officials have spent on these matters. If these past efforts are any indication, I am confident we can continue to work together in the best interests of both Orono and the region.

J. Harrington: dated March 7, 1978, which at this time, have not been clarified. Bob, after our last discussion several weeks ago, we had agreed that you would be forwarding to the City of Orono a reply to our many concerns in sufficient time to allow our staff time to review your report to us which includes information that has been documented over a period of many years.. Now, you are asking us to reply within seven working days to meet a deadline of March 23, 1978 to review a report to the Physical Development Committee and also to meet a deadline of Pdarch 23, 1978 to - request a hearing on our Metropolitan Systems Statement. The decisions made today will set the pattern for future planning in the City of Orono and certainly requires a reasonable time frame to allow for complete staff review of your March 8 letter. I believe our concerns as outlined in our letter to fir. Harrington, 'and copied to you, are valid ones that should receive your attention. I am enclosing another copy of that letter for your review. I would appreciate your sincere consideration of deferring any action on your recommendations to the Physical Development Committee on March 23, and again as outlined previously to Mr. John Boland, we would want to request an extension to the March 23 hearing deadline until we have resolved our many concerns as previously outlined to you.

Box 66 Crystal Bay, MN 55323 Dear Mayor Van Nest: This letter is in response to your letter of March 1, 1978 and a follow-up to previous correspondence regarding comprehensive sewer planning and the Orono -Long Lake Interceptor (MWCC Project No. 71-13). We will look forward to receipt of modifications to Map 1, "Urban - Rural Service Area", which includes the areas identified in your March 1, 1978 letter.- Upon receipt of this information and other information herewith requested, we will forward a copy to the Metropolitan Council and request their review and comments on the Comprehensive Sewer Plan (CSP) dated April, 1977. This CSP (Phase I: 1977-1990) will be considered an interim plan until such time as a CSP is prepared in accordance with the requirements of the Metropolitan Land Planning Act. A review was made of your CSP and comments were made on the plan at the June 17, 1977 meeting of the Metropolitan Council's Physical Development Committee. Our comment at that meeting was that the CSP showed a difference in the Urban Service Area and the Sewer Service Area. This difference was not resolved until we received your letter of February 6, 1978 stating that the City recognized that these areas were synonomous. It is our understanding that the modified Map 1, previously referred to in this letter, will confirm the agreement of the two areas. The CSP also indicates that the City will study and recommend solutions to the sewage disposal problems in areas not having sewer service avail- able. The CSP indicates that alternative solutions will be considered with the installation of sanitary sewers having the lowest priority. It is the intent of the Commission to recognize alternative waste manage- ment systems in the rural areas as we are in the process of initiating the "Alternative Waste Management Study" under our 201 Facility Planning. This Study together with the Metropolitan Council's 208 Program will recommend policies and procedures for on-site systems to be included in an amendment to the Waste Management Policy Plan. A review and comments on rural area sewage systems will be made following the development of the above procedures. These policy and management procedures should be a part of the CSP as prepared under the Metropolitan Land Planning Act. Mr. Brad Van Nest, Mayor City of Orono March 15, 1978 Page Two The CSP indicates that the City will initiate whatever action is necessary to provide adequate intercommunity sewer service in the future. The intercommunity sewer service agreement between your City and the City of Long Lake for the Hackberry Hills states that some action will be required by Orono upon the completion of the Orono -Long Lake Interceptor. We assume that the City of Orono will follow through on any intercommunity sewer needs that are necessary even though the interceptor (as a forcemain) will have a different location than the previously proposed gravity sewer. Since this action may require the installation of a local sewer within a five year period, the CSP should be revised to include a description and tentative time schedule for this improvement. In response to your statements regarding the design of the Orono - Long Lake Interceptor, we again state that the design parameters (population served and time period) are as confirmed in our letter of March 1, 1978. These design parameters are in accordance with the existing and projected sewerage needs of the area. It is the responsibility -of the Commission to provide facilities in accordance with local and metropolitan planning and determine a prudent design life for the facility which is acceptable to the Minnesota Pollution Control Agency and the Environmental Protection Agency. The Commission believes that it has carried out its responsibility for the proper design of this metropolitan interceptor.

Attachments to this letter include Mr. Bernard Harrington's letters -df March 1, 1978 and March 15, 1978, and the City of .Orono's response to Mr Harrington dated March 7, 1978, fir. Robert C. Mazanec's letter to us dated March 8, 1978, and our response to fir. Mazanec dated March 13, 1978. _fir. Mazanec called me the morning.of March 14 after receiving my letter and asked me what the City's concerns -were, at this point in time. I reviewed with him our.problems in communicating, our objections to a revised Systems Statement, that was drafted .by Metropolitan staff without .our knowledge and.also our concerns of not receiving -any comments to our Comprehensive Sewer Plan, which has been before the Metropolitan Waste Control Commission for ten months. Our main concern at this time, is that we have been trying our best through many meetings and mailings to Metro- politan Council and Metropolitan Waste Control Commission staff as documented, to obtain as much information and data as possible allowing us to make reasonable decisions in our planning process and to abide by the Planning Act. As discussed with Mr_ Mazanec, his letter dated March 81 1978, received March 13, 1978, allows us to respond in seven working days to meet a March 23, 1978 deadline to respond to the Physical Development Committee and to request a hearing on the Systems Statement. This deadline does not allow our staff time to review Mr. Mazanec's letter or Mr. Harrington's letter dated March 15, 1978 received today, March 20, 1978. We were assured several months Mr. John Boland March 20, 1978 • Page 2 ago of our concerns with the approaching deadline that we would not be put in a position of not being able to respond within a reasonable time because of the 60 day appeal period termination_ Mr. Mazanec agreed to extend the deadline to meet with the Physical Development Committee until Harch 30, 1978 and advised me to request from you an extension of the March 23 deadline to request a public hearing. We feel that the years it has taken to gather comprehensive data, which.is just now being forwarded to us, certainly justifies an extension to the public hearing deadline. Please advise me as soon as possible of your decision in this matter. Yours truly, Walte R.

Bernard J. Harrington Metropolitan Waste Control Commission 350 Metro Square Building 7th & Robert Streets St. Paul, Minnesota 55101 - Dear Mr. Harrington: This letter is in response to your letter of March 15, 19781 concerning the Orono -Long Lake interceptor as presently proposed for the City of Orono. The comments made -in the last paragraph of your letter of March 15 indicate that the Waste Control Commission has provided answers to -questions raised by the City of Orono pertaining to the sewer service area of the Orono -Long Lake interceptor. The Waste Control Commission has not safisfactorily answered the question that the City of Orono has raised concerning the future capacity of the forcemain for that part of the sewer service area which lies out- side of the proposed MUSA line and in the rural service area. The information contained in your letter of March 1, 1978 does give us the capacity of the lift stations which are designed to handle the projected flow from that portion of Orono which lies within the urban service area. We have compared the flows and population equivalents for the lift stations contained in your letter of March 1. with Addendum #3 of the Engineering Report and the Orono Comprehensive Sewer Plan and they seem to be consistent. In other words, the projected flows of'the lift station would seem to provide a reasonable capacity for a twenty-year period for that part of the City of Orono which lies within.the urban service area. The question which the City has raised, which the Waste Control Commission has not provided an answer, is what is the future capacity and the population equivalents of the forcemain for that portion of the sewer service area which lies within the rural service area of the City of Orono. In other words, the City wishes to know what level of urbanization has been projected by the Waste Control Commission in the sizing of the forcemain to serve that portion of the sewer service area that lies in the rural service area of our City. Mr. Bernard J. Harrington March 23, 1978 • Page 2 During our meeting of February 2, 1978, you indicated to us that, in fact, there was additional hydraulic capacity in the forcemain to serve some future growth in the rural service area of our City and the question that we must have answered before we can support the present design of the Orono interceptor, is what that future capacity is and how you arrived at it. Either the forcemain was designed for additional flows from the rural service area of our City or the sewer service area of the interceptor is incorrectly shown on the map provided with your letter of March 1, 1978. The City would like to have the answer to this question in sufficient time that it can be reviewed by our staff and Council before the Metropolitan Council makes a final determination of the design and specifications of the Orono -Long Lake interceptor. Thank you for your cooperation in this matter. Y rs trul , (� 0 Brad Van est Orono Mayor cc: Representative'Robert L.

Van Nest Mayor, City of Orono Orono, Minnesota Dear Mayor Van Nest: Metropolitan Council 300 Metro Square Building Seventh Street and Robert Street Saint Paul, Minnesota 55101 Telephone (612) 291-6453 Office of the Chairman After our meeting of March 28, 1978, it was agreed that our attorneys would meet and discuss legal issues regarding the Long Lake Interceptor question and City of Orono's system statement. That meeting was held on March 30, 1978, and the purpose of this letter is to foi=mally state the agreement reached at that time. The following has been reported to me as conclusions reached in that meeting and are agreeable to me: • 1. Orono will submit an interim comprehensive sewer plan identifying the sewer service area set forth on the map dated March 17, 1978, used at the meeting, as an interim local sewer service area covering the time period between now and 1980 or whenever the Land Planning Act comprehensive plan is prepared by Orono and approved by the Metropolitan Council, which ever occurs first. 2. The MUSA line and the Metropolitan Sewer Service Region line will at this time remain unchanged. After the Land Planning Act comprehensive plan has been prepared by Orono and reviewed by its adjacent governmental units and affected school districts, the MUSA and MSSR may, as appropriate, be changed via the system plan amendment process established by Minn. Stat. Sections 473.145 and 473.146.and the Waste Management Policy Plan. 3. Orono's ultimate sewer capacity in the Long Lake inter- ceptor is 1.09 million gallons per day. Orono may plan for the use of that capacity as it sees fit and may allocate the capacity as it feels appropriate within the confines of the service area designated in the interceptor design plans and specifications. Following the meeting, staff has reviewed all drafts of the Orono system statement. Accompanying this letter is a revision of the Orono system statement which reflects the above agreed • upon sewer capacity, and, I hope, reflects the agreement reached at the meeting of March 30. As you may recall, the Metropolitan Mayor of Orono Page Two • March 31, 1978 Council's population projections were amended in December... The new population forecasts, which are lower, are not included in the system statement, because the system plans have not been formally amended yet. However, we recommend you use these new figures in your local plans, because metropolitan plans will be based on them in the future. These new forecasts are as follows: Households Population Employment 1990 2800 9000 1000 2000 3400 11000 2500 New forecasts result in a 1990 sewer flow estimate of .58 mgd (sewered population 6,900); .01 mgd industrial flow and a traffic estimate of 44,000 person trips per day in 1990. These figures are further explained in Bob Mazanec's letter of March 8, 1978. By this letter Orono's request for an extension of time to April 20, 1978, within which to appeal the system statement and • for review of plans and specifications of the proposed Orono - Long Lake interceptor is granted. If you have any problems with the content of this letter, please contact either John Hoeft or Robert Mazanec of the Council staff.

Olson The letter dated March 31, 1978, from John Boland to Mayor VanNest fairly represents the items discussed and the understandings reached between the Mayor of Orono, the MWCC Staff and the Council Staff at the meetings of March 27 and March 30 at the Metropolitan Council offices. The City of Orono's support of the Orono -Long Lake facility, prior to actually relocating the MUSA line and the MSSR line is a policy ques- tion to be resolved by the Orono City Council. The Orono Council will be considering this matter in the very near future. s Our firm has been directed by the City of Orono to prepare an interim CSP, to the year 1980, as discussed at the March 30 meeting. We under- stand that your office will be forwarding a set of guidelines to use in the preparation of the interim CSP. In order to assist in the preparation of the interim CSP and to aid the City Council in the eval- uation of the policy decision to support the Orono -Long Lake Interceptor, we have been requested to seek clarification of several specific items, as follows: 1) What is the correct amount of the ultimate capacity of the Orono -Long Lake Interceptor? The revised System Statement, Page 19, lists the ultimate average daily flow at 1.71 MGD. Addendum No. 3, - revised Table 10 of the Preliminary Engineering Report in- dicates 1.77 MGD. 2) What is the correct amount of the Ultimate design flow from Orono? • The revised System Statement, Page 19, lists the amount at 1.09 MGD. Addendum No. 3, revised Table 10, indicates 1.14 MGD. Page 1. Mr. Robert Mazanec April 10, 1978 Senior Planner Metropolitan Council 300 Metro Square Building St. Paul, Minnesota 55101 Re: Orono -Long Lake Interceptor Our File No. 139 3) What the correct criteria used to determine the design capa- city per capita for the Orono -Long Lake Facility? The Orono Comprehensive Sewer Plan and the Preliminary - Engineering Report, Addendum No. 1, Page 11, dated April, 1976, indicated 115 gallons per capita per day. Mr. Boland's letter of March 31, 1978, which referred to Mr. Mazanec's letter dated March 8, 1978, indicates 83 gallons per capita per day. The City of Orono intends to use 115 gpcpd and 3.2 people per unit when preparing the interim CSP. A map showing the urban service area and the rural service area which Orono also intends to use for the interim CSP is attached. • Your timely response to the above questions will be appreciated.
