BOCC 4/26/99 PROJECT INFORMATION AND STAFF COMMENTS PROJECT: Spring Valley Sanitation District Amended Service Plan LOCATION: The proposed district is located in portions of Sections 14-16, 19-23, 26-35, T.6S., R88 W; portions of Sections 24, 25, 35 and 36, T6S, R89W; and portions of Sections 3-9, T7S, R88W more practically described as an area known as the south portion of Spring Valley off of County Roads 114 and 115. I. PROJECT DESCRIPTION The Spring Valley Sanitation District is proposing to amend the existing district boundaries established in July of 1979, to address regional wastewater treatment needs. The existing district boundaries include 1787 acres of land that is made up of portions of the Los Amigos Ranch PUD, CMC Campus, Auburn Ridge and Pinon Pines apartments. The proposed district would add 10,726 acres of land that is made up of other portions of the Los Amigos Ranch PUD, Spring Valley Ranch PUD, Lake Springs Ranch PUD, the Kendall Ranch and other lands. The entire district would be 12,513 acres in size, if the amended service plan is approved. The existing district has 189.5 EQR's or an estimated Populations Equivalent of 664 people. The proposed amended district would have a projected total of 1,571 EQR's and a Population Equivalent (PE) of 5,499 people. All of the projections are based upon the proposed plans of various property owners in the area and some estimations on other properties. Also included in the projections are estimates of EQR's and a PE based upon the proposed Comprehensive Plan densities. According to the applicants interpretation of the Comprehensive Plan, there could be 4,057 EQR's and a PE of 14,201. The existing wastewater treatment facility can treat up to 53,000 gpd or 189.5 EQR. Additional service requests have come from property owners within the district and outside the district boundaries. A wastewater collection system and a 550,000 gpd treatment facility are being designed to meet the regional wastewater treatment needs of the area based upon the anticipated density. The treatment facility will be designed to meet tertiary discharge requirements. The existing wastewater is collected in a gravity sewer line system, but due to topography, wastewater lift stations and associated forced mains will be needed to -1- accommodate much of the proposed new and expanded service area. The collection system will be designed to accommodate additional flows from property to the north and west. The estimated cost of the construction of the new plant and associated infrastructure originally was $5,100,000, but after further analysis has been reduced to $4,100,000. (See pgs. /3—/6 ) The 20 year operating and maintenance costs are estimated at $1,800,000. Several property owners in the District service area will make capital cost contributions to fund construction of the plant and related infrastructure. Additional funding may come from credit enhanced revenue bonds or a low-interest revenue -based loan from the Colorado Water Resources and Power Development Authority. Tap fees and service charges will be used to repay construction obligations and annual operation and maintenance of the facility. II. ISSUES AND COMMENTS A. Colorado Revised Statutes - C.R.S. 32-1-101, et. seq. Within 30 days of the filing of a service plan with the County Clerk and Recorder, the Clerk and Recorder is required to deliver the service plan to the Planning Commission for review and recommendation. The Planning Commission is required to make a recommendation to the Board of County Commissioners to take one of the following actions: 1. Approve, without condition or modification, the service plan. 2. Disapprove the service plan. 3. Conditionally approve the service plan subject to additional information being submitted or the modification of the proposed service plan. The Board of County Commissioners "shall disapprove the service plan unless evidence satisfactory to the Board of each of the following is presented": 1. There is sufficient existing and projected need for organized service in the area to be serviced by the proposed special district. 2. The existing service in the area to be served by the proposed special district is inadequate for present and projected needs. 3. The proposed special district is capable of providing economical and sufficient service to the area within its proposed boundaries. 4. The area to be included in the proposed special district has, or will have, the fmancial ability to discharge the proposed indebtedness on a reasonable basis. -2- The Board of County Commissioners may disapprove the plan if evidence satisfactory to the Board of any of the following, at the discretion of the Board, is not presented: 1. Adequate service is not, or will not be, available to the area through the County or other existing municipal or quasi -municipal corporations, including existing special districts, within a reasonable time and on a comparable basis. 2. The facility and service standards of the proposed special district are compatible with the facility and service standards of each County within which the proposed special district is to be located and each municipality which is an interested party under Section 32-1-204(1). 3. The proposal is in substantial compliance with a master plan adopted pursuant to Section 30-28-108, C.R.S.. 4. The proposal is in compliance with any duly adopted county, regional or state long-range water quality management plan for the area. 5. The creation of the proposed special district will be in the best interests of the area proposed to be served. The following are responses to the statutory criteria: 1. There is sufficient existing and projected need for organized service in the area to be serviced by the proposed special district. The Spring Valley area has a number of already approved developments requiring sewage treatment. Los Amigos Ranch PUD, Filings 6-10 was approved with the requirement that a central sewage disposal system be developed for the project. Other older developments (Lake Springs Ranch PUD, Spring Valley Ranch PUD) are being revised and will require central sewage disposal facilities as envisioned. Any other property proposed for inclusion in the district would need central sewage disposal, if they are developed, given the need to protect the Spring Valley aquifer. 2. The existing service in the area to be served by the proposed special district is inadequate for present and projected needs. The present system is inadequate to meet the immediate and near future demands for sewage treatment for the existing development in the area. The present system is at capacity and there are other property owners within the existing district boundaries wanting service. The other properties to be included in the district would increase the sewage treatment demands by a ten -fold factor and would far exceed any capabilities of the existing treatment capabilities. -3- 3. The proposed special district is capable of providing economical and sufficient service to the area within its proposed boundaries. The proposed district will need to invest an estimated $4.1 million to build all of the infrastructure to meet the proposed demand for service. Of that cost, $2,937,566 will be the cost of the new treatment facility. The remaining portions of the cost will be for lift stations and force mains. Bob Szrot, County Engineer reviewed the original application and supplemental material submitted and concluded that there are still questniaas about the method and cost of treatment facilities. (See letters pgs.20 ) He posed a number of questions related to the District's ability to provide sufficient and economic service to the area. He questioned the District's demonstration of the ability to meet the discharge standards and the sufficiency of the service, given the proposed design. At the Planning Commission meeting additional information was submitted was submitted by the District representatives in response to the staff's concerns. ( See pgs. 2.71 ) Staff reviewed the information submitted subsequent to the meeting and still had some questions regarding the district's ability to provide economical and sufficient servi e, given the uncertainty of the discharge parameters. (See memo pgs.% rf) It appears that the District's ability to meet the present effluent standards are tied to their ability to get approval for land application. There is a possibility that the standards may be changed, based upon the redesignation of Landis Creek in terms of water quality standards. But, the change cannot be proposed until later in the year, when the Colorado Water Quality Commission will consider requests for this drainage. Staff also does not understand why it would cost $9.00/gal. to build a plant at the Roaring Fork Sanitation District that has to meet lesser discharge standards than the SVSD/Landis Creek standards. The same size plant is only $5.35/gal. as proposed for the Spring Valley site. There is still the assumption in the figures for connecting to the Roaring Fork Sanitation District that all of the costs for extending the interceptor sewer/lift station will have to be absorbed by the SVSD. Staff would also wonder why the out of district tap fees would be applicable, since it would seem to logical to annex to the district for economic and political reasons. -4- 4. The area to be included in the proposed special district has, or will have, the financial ability to discharge the proposed indebtedness on a reasonable basis. The district has commitments from a number of the proposed landowners to pay for the cost of the capital improvements, along with proposed loans. Included isanAlysis by Blake Jordan, bond counsel for the County. (See letter pgs. 2411// ) Mr. Jordan has provided some suggested language for inclusion in the Service Plan that has been used by other Counties in the approval of a Service Plan. The Planning Commission recommended that the language be included as a part of the final Service Plan amendments. The following discussion addresses the reasons the Board of County Commissioners may deny a service plan: 1. Adequate service is not, or will not be, available to the area through the County or other existing municipal or quasi -municipal corporations, including existing special districts, within a reasonable time and on a comparable basis. The District has provided additional documentation to support the statement that the Roaring Fork Water and Sanitation District is not a viable alternative for the provision of sewage treatment service to the area. There is a letter inthis supplementary documentation from the RFWSD legal counsel stating that the district is not capable of handling the sewage disposal needs of the SVSD. The initial response was based upon the RFWSD having a 600,000 gpd maximum capacity identified in their service plan and number of existing commiments to other properties in their service area and expanded service area. Staff questioned these numbers based upon representations made during the Cattle Creek Ranch PUD application that the RFWSD could grow to up to 1.2 mgd. The District's additional information submitted at the Planning Commission meeting expanded on that issue. If the SVSD is only developed to the projected 1571 EQR's or 550,000 gpd, the RFWSD has the potential to accomodate the projected growth, but the argument is that the plant must be capable of handling the maximum projected by the Comprehensive Plan. If this is the arguement, the applicant's have not demonstrated that they can deal with the 1.5 million gpd, with the potential worst case effluent limitations. Air' ,4G XIV" 1 1 Ver //G47 p /Q n 's' The initial supplemental documentation submitted for the application stated that it will cost $8.1 million to connect into the Roaring Fork Sanitation District (See attached pgs. 9�' /q ). The construction cost of the -5- infrastructure to connect the Spring Valley area to the RFSD facilities was projected to be $1,987,897, with $6,126,900 in tap fees. As noted previously if appears that the projected connection costs are being totally attributed to the Spring Valley Sanitation District. When it is more than likely the costs will be shared by other property owners needing to connect with the RFSD. The actual cost to the Spring Valley Sanitation District would probably be at least 25% less than projected. As noted in the County Engineer's original memo, the Colorado Water Quality Control Commission recently instituted a new policy regarding the consolidation of facilities. The policy requires a financial feasibility analysis of connecting to facilities within a five (5) mile radius of a proposed new or upgraded plant as a part of the site application process. Even with the additional documentation submitted with this application, there are still questions regarding the consolidation issue. 2. The facility and service standards of the proposed special district are compatible with the facility and service standards of each County within which the proposed special district is to be located and each municipality which is an interested party under Section 32-1-204(1). As noted previously, the CDPHE has established Preliminary Effluent Standards for the Spring Valley Sanitation District. It is staff's understanding that these standards are not changed in a significant manner for the approval of a site application for a sewage disposal facility. The District has stated that they will meet the standards imposed by the State. It has not been demonstrated to staff that the district can meet the effluent standards being imposed The standards to be imposed are very difficult to meet and the plans submitted leave a lot of questions about the proposed treatment facility being able to meet the limits.. Particullarly, if the district has to plan for a 1.5 million gpd plant, with land application necessary to meet standards and no ground water discharge in the winter. 3. The proposal is in substantial compliance with a master plan adopted pursuant to Section 30-28-108, C.R.S.. The Garfield County Comprehensive Plan, Study Area I notes three different designations on the Proposed Land Use Districts Map. The majority of the proposed new service area is identified as being Medium Density Residential (6 to less than 10 ac/du), with a smaller areas identified as Low Density Residential (10 and greater ac/du) or Existing Subdivision. The present district is located in an area identified as Existing Subdivision and Public Institution. The projected densities do not appear to be inconsistent with the -6- Comprehensive Plan designations. The Water and Sewer Services Goal states the following: To ensure the provision of legal, adequate, dependable, cost effective and environmentally sound sewer and water services for new development. The following objectives are relevant to the proposed service plan : 7.1 Development located adjacent to municipalities or sanitation districts with available capacity in their central water/sewer systems will be strongly encouraged to tie into these systems. 7.4 Development will be required to mitigate the impact of the proposed project on existing water and sewer systems. 7.5 Garfield County will strongly discourage the proliferation of private water and sewer systems. The following policies are relevant to the proposed service plan : 7.1 All development proposals in rural areas without existing central water or sewer systems will be required to show that legal, adequate, dependable and environmentally sound water and sewage disposal facilities can be provided before project approval. 7.2 Where logical, legal and economic extension of service lines from an existing water and/or sewage system can occur, the County will require development adjacent to or within a reasonable distance, to enter into the appropriate agreements to receive service. The burden of proof regarding logical, legal and economic constraints will be on the developer. The proposed service plan amendment is consistent with the Comprehensive Plan in terms of developing a central sewage disposal system for an area. 4. The proposal is in compliance with any duly adopted county, regional or state long-range water quality management plan for the area. The Water Quality Management Plan for Region 11(208 Plan) identifies a need for an analysis of the Spring Valley area populations, consolidation of facilities and treatment requirements prior to the approval of any additional site applications. (See pg. 97.-- ) Subsequent approval of the SVSD site -7- application has occurred, but without the analysis identified. The present application has provided additional analysis of these issues, but as noted previously, is not convincing to staff, in the arguments for the preferred alternative. S. The creation of the proposed special district will be in the best interests of the area proposed to be served. If development is to occur in the proposed service area, a central sewage disposal system is appropriate and is in the interest of the area to be served. The primary question is still whether or not SVSD should expand or try to connect to the RFWSD. III. RECOMMENDATION The Planning Commission reviewed the application and recommended approval of the proposed service plan amendment with the following condition of approval: 1. That the District add the language to the service plan recommended by Blake Jordan, Sherman and Howard L.L.C., in his February 23, 1999 letter. Staff does not support the approval of the proposed service plan amendments based upon the lack of satisfactory evidence that the district can provide economical and sufficient service without knowing that they can design a plant in the Spring Valley area that can meet standards and that there is the possibility that service could be provided by the Roaring Fork Water and Sanitation District if the worst case scenario is not used. The following are the criteria that could be used as a basis for not approving the proposed service plan amendment.: 1. The proposed special district is capable of providing economical and sufficient service to the area within its proposed boundaries. 2. Adequate service is not, or will not be, available to the area through the County or other existing municipal or quasi -municipal corporations, including existing special districts, within a reasonable time and on a comparable basis. -8- LEAVENWORTH & TESTER, P.C.

This letter also confirms the District's agreement to postpone the Garfield County Planning and Zoning Commission hearing for such Amended Service Plan to March 24, 1999. As a point of clarification, the District is submitting the Amended Service Plan and the enclosed supplemental information pursuant to C.R.S. §32-1-207(2), which requires approval by the Board of County Commissioners of material modifications to the service plan as originally approved. A resolution of approval by the Board,of County Commissioners under the statute is to be adopted in substantially the same manner as is provided for the approval of an original service plan; therefore, the District has submitted its service plan and supplemental information with the intent to satisfy the criteria for "service plans" contained in C.R.S. §32-1-203. If your interpretation of the statutory provision differs from the District's, please inform me at your earliest convenience. Enclosed is a letter from Dean Gordon, P.E., the District Engineer, which addresses review comments contained in the February 22, 1999 staff memo to the District from Bob Szrot, P.E., County Engineer. We anticipate that the clarifications contained in Mr. Gordon's letter will allow the County Engineer to confirm his recommendation of approval of the District's Amended Service Plan. Also enclosed is a letter from the District Engineer addressing information and clarifications you requested in our telephone conversation at the end of February. The District Engineer's letter includes a breakdown of capital costs, and please note that the District's estimate of capital cost for construction of a new regional wastewater treatment facility has decreased from F:119991Letiers-Memos\SVSD-DeFord-ltr- l.wpd 9 ...... ..... LEAVENWORTH & TESTER, P.C. Don DeFord, Esq. Page 2 March 11, 1999 the total cost identified in the Amended Service Plan. The letter also contains confirmation of the District's ability to meet preliminary discharge parameters established by the State. I must emphasize that, pending the State's final determination on the discharge parameters, the District will proceed with alternative discharge options, including direct discharge to Landis Creek and land application in the Spring Valley area. Finally, the District Engineer has detailed the costs required to transport effluent from entities requesting central sewer service in the Spring Valley area to the Roaring Fork Water and Sanitation District site located near the Aspen Glen Subdivision. As you can see, the costs associated with infrastructure and transportation to the Roaring Fork Water and Sanitation District are prohibitive (approximately $3 Million more than the District option). In addition, the enclosed letter from the Roaring Fork Water and Sanitation District confirms that such District is unable and unwilling to accept and treat sewage from the Spring Valley area. I trust the enclosed information will provide a comprehensive supplement to the District's Amended Service Plan, and we look forward to meeting with the Garfield County Planning and Zoning Commission on March 24, 1999 to further discuss the District's Amended Service Plan. Should you need any additional information or clarifications, please do not hesitate to contact me at your convenience. LEL:bsl Enclosure cc w/enc.: SVSD Board of Directors Anne J. Castle, Esq.

That memo has been forwarded on to me. Referencing your memo, please consider the following: 1. Consistently throughout the Amended Service Plan, we have used the equivalency of 1 EQR = 350 gpd. We have further assumed that an EQR is equivalent to a residential occupancy of 3.5 persons with a daily per capita use of 100 gpd. 2. I felt the easiest way to address your request for additional mapping was to use a colored map for clarification. I have included that map with this correspondence. We would be able to reproduce additional copies of this as needed for hearings before the Planning & Zoning Commission and/or County Commissioners. Those areas indicated as "unallocated" are best explained by referring to the table on Page 1 1 . Item D, Unallocated - Expanded District Service Area, indicates the EQR and population equivalent densities assumed for the unallocated area. All the areas EXCEPT the unallocated areas have been identified in the Amended Service Plan as having an existing or planned development associated with them. The balance of the properties, referred to as unallocated properties, do not have specific development plans and, therefore, were dealt with in the aggregate as shown on Page 11. The last columns indicate what the EQR and population equivalent would be if the Comprehensive Plan approved densities were strictly followed. The middle two columns indicate the density assumed for this Amended Service Plan. All the unallocated areas are included within the proposed service area. 3. With respect to the anticipated facilities to be constructed, attached is a drawing of the treatment facility site showing both existing and proposed facilities. A conceptual sizing of facilities is also shown based on preliminary information from equipment manufacturers. The approximate footprint shown is 2.5 acres. Note that the existing facilities will be abandoned. Alternately, I would like to address your comment by noting the following treatment plant facilities in the area, their size and the approximate area dedicated to wastewater treatment: March 9, 1999 Mr. Bob Szrot, P.E. Page 2 TREATMENT FACILITY DESIGN CAPACITY ACREAGE City of Glenwood Springs 2.3 MGD 4 Town of Carbondale 1.5 MGD 3.5 Roaring Fork Sanitation District (Aspen Glen) 1.2 MGD 5 Mid Valley Metropolitan District 1.2 MGD 4 Battlement Mesa Metropolitan District 2.4 MGD 7 I have attempted to bracket the Amended Service Plan capacity for the SVSD facility as well as the potential for expansion to 1 .5 MGD. You will note there is a wide variation in the acreage devoted to wastewater treatment in all of these situations. That is because the acreage is dependent upon the type of wastewater process utilized and the extent to which the various treatment components are separated from each other which, obviously, in turn is dependent upon the amount of acreage available in the first place. As you will note for the anticipated service needs is 0.55 MGD, an acreage in the amount of 2 to 3 acres is sufficient. Even at a Comprehensive Plan maximum service requirement of 1.5 MGD, 5 acres is sufficient for any anticipated needs. 4. Please see discussion in No. 3 above. In anticipation of the upcoming Planning & Zoning Commission hearing, I would like to discuss both your memo and this response well in advance so that we might have a complete packet of information available at that meeting.

Leavenworth & Tester, P.C. Attorneys at Law P.O. Drawer 2030 Glenwood Springs CO 81602 RE: Spring Valley Sanitation District Amended Service Plan Dear Lee: At your request, I am providing additional information with respect to the Amended Service Plan submitted on behalf of Spring Valley Sanitation District (SVSD). My understanding is this request for additional information comes from County staff during their review of the plan. Breakdown of Costs Attached hereto are several tables which indicate the breakdown of the estimated capital costs. There are four components to the capital cost figure, the tertiary treatment itself and three different interceptor sewerlines consisting of a pump station and force main for each installation. Please note that, at the time the Amended Service Plan was done last month, the estimated costs for the tertiary treatment plant were $3,971,000. The attached breakdown represents additional work we have done in the interim period on estimating of costs for plant facility. We have had a chance to get further information from potential equipment manufacturers as well as contractors who specialize in the type of work required. The breakdown indicates a total estimated plant cost of $2,937,566. Therefore, this would decrease the total estimated capital costs for the service plan from $5.1 million to $4.1 million. Connection to Roaring Fork Water & Sanitation District (RFSD) Also attached hereto is a table indicating the estimated costs for connection to the RFSD, formerly known as the Aspen Glen Water & Sanitation District. Those costs are estimated at $8.1 million. Please note, however, that RFSD has indicated that treatment of waste from Spring Valley is not an option they are able to consider. Therefore, these costs should be considered for comparison purposes only and not representative of a viable alternative for treatment of wastes from Spring Valley. Preliminary Effluent Limitations We have received a letter from the Colorado Department of Public Health and Environment (CDPHE) concerning preliminary effluent limitations. The ammonia limitation is the only effluent parameter which is not readily obtainable by existing wastewater treatment March 11, 1999 Lee Leavenworth, Esq. Page 2 technology. The ammonia limitations given will require that the effluent from the facility be land applied rather than direct discharges to a receiving stream. As you know, discussions have been held with landowners within the district and we believe there are more potential users for effluent than there is effluent available so that using land application will not be a restraint to treatment. I should also point out that we have ongoing discussions with the CDPHE concerning the classification of the receiving stream in Spring Valley, assumed by the State to be Landis Creek. We anticipate that under any reclassification considered, tertiary treatment would still be required, but that tertiary treatment technology exists that would allow direct discharge to the receiving environment.

SZROT, County Engineer This memo is intended to compliment the previous February 22, 1999 memo pertaining to my review of the February, 1999 Amended Service Plan. 1 had previously discussed several minor concerns relating to correlation of EQR's, defining unallocated areas, and general descriptions of the facilities to be built. Since this memo, I have received a copy of the February 4, 1999 letter pertaining to Preliminary Effluent Limits; Spring Valley Sanitation District addressed to Mr. Dean Gordon. This letter has raised some concerns about the ability of the proposed Spring Valley wastewater treatment facility to be able to meet effluent discharge standards and the cost economics and process sizing involved in meeting the proposed standards. I must insist that a more in-depth analysis be conducted to demonstrate how the proposed processes will meet the Total Ammonia discharge limitations for the stated values. II would like to see detailed descriptions of anticipated influent and effluent values for each process parameter. Of primary concern is the discharge limits to the adjacent tributary of Landis creek. Initially this creek was credited with a dilution flow rate of .1 cfs. The assumption was made that the existing dilution flow was primarily pure water. Subsequent discussions have raised question to the existing quality of this water and its ability to dilute the proposed effluent flows. The listed discharge limitations for Total Ammonia for November (.35mg/1), December (.35mg/I), and January (.09mg/I) reinforce the requirement to have better documentation of the proposed plant processes and their respective removal rates. From discussion with several industry professionals and literature review, it appears that Total Ammonia (as N) is typically present in discharge effluent at rates in excess of 1.0mg/I in even the most advanced systems. This rate would be out of compliance for all months except February. 1 109 8th Street, Suite 300, Glenwood Springs, CO 81601-3363 (970) 945-5004 FAX (970) 945-7785 Comment was heard that there might be plans for an effluent storage facility that would hold the discharge waters until a time that they would be able to achieve discharge into the Landis tributary, I have not seen any plans for this scenario. A final note is the question of economics. I would like to see if the process costs have changed with this new information. In addition, there has been a rejection of the possibility to pipe wastewater to the Aspen Glen facility as being cost prohibitive, yet the majority of this cost is based on $6M in tap fees. 1 would like to see a more representative breakdown of capital structure costs with the piping option. I have also been advised that the upcoming State regulations will examine more closely these economics if a treatment facility is within 5 miles to the area of need. I still support tertiary wastewater treatment in a regionalized setting, however, I must withdraw my support until more clarification is documented in light of seemingly unattainable effluent limitations for this proposed facility. Robert B. Szro°t, P.E. Garfield County Engineer February 22, 1999 Memorandum To: File Re: Spring Valley Sanitation District — Amended Service Plan ROBERT B. SZROT, County Engineer I have reviewed the February, 1999 Amended Service Plan document and have the following comments. I feel that it is a well -needed concept to provide centralized regional solutions for wastewater treatment. The expansion of the sanitary district, increasing waste treatment to tertiary standards, and the planned reuse of effluent flows are logical remedies for this service area. I have several minor issues that I would like to see addressed prior to adoption of this document. 1) Page 6 — I would like to see a correlation included that specifically relates EQR's to gpd flows. For the purpose of this report — approximately how many gpd's = 1 EQR? I have seen several definitions in the industry and would like clarification to this question. 2) Ill -A, 111-B — I would like to see one map (in addition to those presented) that overlays the existing service area with the future intended service. area. This would help relate visually the proportionality of the geographic dimension changes. I also would like to know why some areas are "unallocated" and the specific meaning of this concept as it relates to this report. Does this term represent non-inclusion of these areas into the service area? 3) Section IV. General Description of Facilities to Be Constructed — I would like to see a conceptual sketch of the anticipated future treatment facility with the associated anticipated processes. Please show the anticipated process flow for achieving tertiary treatment and approximate sizes of process units. Although this does not need to be a "formal" presentation, I would like to know anticipated tank sizes, 22- 109 8th Street, Suite 300, Glenwood Springs, CO 81601-3363 (970) 945-5004 FAX (970) 945-7785 digester size, sludge processes, and see how the footprint of these processes are anticipated to occupy the existing plant site. 4) In relation to Comment 3 — The future planned waste treatment plant will process .5MGD flow rates. The Comprehensive Plan figures would anticipate maximum density flows of 1.5MGD. With the consideration of the existing plant site at 9.8 acres — contractually expandable to 25 acres and the anticipation of reusing effluent water within the service area, I would like to see the following question addressed in conceptual forrn: Could the current site accommodate an expansion of the future .5MGD plant to 1.5MGD and will the future plant be designed (and have room) to add parallel processes to facilitate an expansion from .5MGD to 1.5MGD. I would have no expectations nor requirements to have any kind of documentation for this 1.5MGD expansion — at this time, but feel that a little forethought might be in order and would like a brief conceptual comment included as to the possibility of this scenario. In conclusion, I was pleased to see the concept of regionalized tertiary wastewater treatment being brought forward in such a cooperative manner. Aside from several clarification issues and foresight concerns, I would support this Amended Service Plan for the Spring Valley Sanitation District.

This letter is submitted to you as supplemental information for the SVSD Amended Service Plan, which includes an analysis of cost and feasibility of obtaining wastewater treatment services from RFWSD. SVSD examined the possibility of consolidation with RFWSD in 1998 as part of its proposed plant facility upgrade and expansion. RFWSD indicated its existing site is sufficient for a tertiary treatment facility which could serve its Service Area and Expanded Service Area, but could not provide service to the Spring Valley area. The contents of Mr. Green's letter confirms this conclusion, which was reached by the RFWSD Board in November, 1998.

Drawer 2030 Glenwood Springs, CO 81602 Dear Lee: Telephone: 970.945.6546 Facsimile: 970.945.9769 February 25, 1999 OF COUNSEL: KENNETH BALCOMB Re: Roaring Fork Water & Sanitation District/Spring Valley Sanitation District I am writing on behalf of the Roaring Fork Water & Sanitation District (the "Roaring Fork District"), formerly known as the Aspen Glen Water & Sanitation District. As you will recall, by letter dated October 19, 1998, Greg Hall of your office inquired whether or not the Roaring Fork District would be willing and able to provide wastewater treatment services to the present and future users of the Spring Valley Sanitation District. Since that letter, the Board of Directors of the Roaring Fork District has had a number of discussions on this issue, most particularly at its meetings on October 28, 1998 and November 25, 1998. Throughout these discussions, it has been the unanimous and consistent conclusion of the Board that the Roaring Fork District is unable to provide sewer service to the Spring Valley area. I have advised you and the Spring Valley Sanitation District Board of this conclusion on a number of occasions, but, as a result of a request by Garfield County, you have now asked that I offer a written explanation of the Roaring Fork District's decision. The Service Plan for the Roaring Fork District was approved by Garfield County after a lengthy series of public hearings on January 31, 1994 by Resolution No. 94-008. A major part of the foundation of the Service Plan was a study commissioned by Aspen Glen Golf Partners at the request of the Colorado Department ofHealth entitled "Wastewater Management Study, Lower Roaring Fork Planning Area" (the "Wastewater Management Study"). The purpose of the Wastewater Management Study was to determine the most cost effective and appropriate wastewater treatment facility for the proposed Aspen Glen development and the surrounding area. The Wastewater Management Study, and hence the Service Plan, identified a "Service Area" and an "Expanded Service Area" which could potentially receive wastewater treatment service from a facility located at the proposed site of the Roaring Fork District's facility. The Wastewater Management Study also considered the Spring Valley area and concluded that it would not be appropriate for the Roaring Fork District and its proposed site to provide service to the Spring Valley area because it would be prohibitively expensive and the proposed site would be inadequate. The Wastewater Management Study concluded: "If it is necessary for Spring Valley to upgrade their system, the most feasible approach will be to provide improvements to the existing treatment plant at Spring Valley rather than extend an interceptor line to the nearest regional treatment plant." The Service Plan thus proposed that the Roaring Fork District be conveyed a site of approximately 6.5 acres, which would be large enough to accommodate a tertiary treatment facility which could provide service to the Roaring Fork District's Service Area and Expanded Service Area as identified in the Service Plan. As submitted, the initial draft of the Service Plan proposed that such facility would be constructed to a maximum capacity of 320,000 gallons per day. However, during the public hearing process, and as a result of Out -of -District Service Contracts approved by Garfield County as part of the Service Plan, the proposed Service Plan was amended to provide that the Roaring Fork District's site would be the site for a regionalized wastewater treatment plant which would have an ultimate treatment capacity of 600,000 gallons per day, the estimated total capacity need for the Roaring Fork District's Service Area and Expanded Service Area. Consistent with the terms and conditions of the approved Service Plan, and the underlying Wastewater Management Study, the Roaring Fork District now owns a site of 6.5 acres. It owns and operates a tertiary wastewater treatment plant having a constructed and operating capacity of 107,000 gallons per day, with preliminary designs for expansion to an ultimate capacity of 600,000 gallons per day. The Roaring Fork District believes that if it were to provide service to the Spring Valley area it would be unable to provide service to its own Service Area and Expanded Service Area as identified in its Service Plan. The District has concluded that its first responsibility is to satisfy the present and future needs of property owners within its own Service Area and Expanded Service Area. Its treatment plant and site are designed to enable the District to satisfy that responsibility. The Roaring Fork District has thus concluded that it is not able to provide wastewater treatment service to the Spring Valley area. A portion of the minutes from the Roaring Fork District's Board meeting of October 28, 1998 setting forth this conclusion is attached. . Please do not hesitate to contact me if you have any further questions in regard to this matter. Very truly yours, BALCOMB & GREEN, P.C.

Although perhaps not evident from a reading of the Amended Service Plan, the Spring Valley Sanitation District Board of Directors has, in conjunction with those property owners requesting service, analyzed the various options available in some detail over a lengthy period of time, and at considerable expense. The purpose of this letter is to outline several relevant factors of which the Commission should be aware as it evaluates this issue. We believe that, after a review of this additional information, the Commission will find that the Roaring Fork District does not represent a viable option, both legally or economically, nor is it consistent with the review criteria under which a service plan is to be evaluated. 1. Roaring Fork Water and Sanitation District Approved Service Plan. At the time the Aspen Glen PUD development was proceeding through the County land use review process, the County made it clear that it wanted a Title 32 Special District, such as a water and sanitation district, to be in charge of the provision of water and sewer services, and that sewer service, at best, should be available on a regional basis. (See, Condition No. 25 of Resolution No. 92-056, approving PUD zoning for Aspen Glen, which resolution directed that the developer of the Aspen Glen PUD organize a special district "for the construction, maintenance and operation of a regional wastewater treatment facility.")

Planning and Zoning Commission Garfield County Building & Planning Department Page 2 March 24, 1999 As a result, a report entitled "Wastewater Management Study of the Lower Roaring Fork Planning Area," dated April 23, 1993, was prepared by WestWater Engineering. Relevant portions of this study are attached as Exhibit A. The purpose of this study "was to determine the most feasible wastewater treatment disposal plan to serve existing and future development in the Lower Roaring Fork Wastewater Planning Area." "The method of analysis and format for the study resemble a condensed version of an EPA facility plan (201 plan)." See, Cover Letter, Exhibit A. As is evident from a review of selected pages of the study, the inclusion of the Spring Valley area was specifically considered and rejected as a non-viable option. At page 6-29, the report concludes "upgrading the existing Spring Valley WWTP is considerably less expensive than connecting to a regional system, in part because of the considerable length of outfall line required." The report looked at a potential pipeline to Cattle Creek as well as along the County Road 114 right-of-way. See, Page 6-28, Exhibit A. The conclusion of the report regarding the Spring Valley area set forth on Page 2 of the Cover Letter reads as follows: It is not cost effective to connect the Spring Valley/CMC plant and the Carbondale plants to a regional system at this time. We believe the same conclusion is true today. Based on that study, the Service Plan for the Aspen Glen Water and Sanitation District dated November 1993 was submitted. The service plan identifies an initial service area and an expanded service area. A copy of relevant portions of the Aspen Glen Water and Sanitation District service plan is attached as Exhibit B. It is clear from the map outlining the service area and a review of the selected pages that, based on the Wastewater Management Study prepared by West Water Engineering, the Service Plan for the Roaring Fork District does not include the Spring Valley area. Further, the Roaring Fork District Service Plan was expressly approved by Garfield County under the same review criteria by which the Commission is to evaluate the Spring Valley Sanitation District Amended Service Plan. Thus, the County has already fully considered this issue and has determined that the Roaring Fork District WWTP facility should not serve the Spring Valley area. Finally, it is important to note that the Roaring Fork District has already acted upon an inquiry as to the availability of service and has rejected the concept. See, Letter from Lawrence R. Green to Leavenworth & Tester, P.C., on behalf of the Roaring Fork Water and Sanitation District, dated February 25, 1999, attached hereto as Exhibit C. Moreover, other potential users F:\1999\Letters-Memos\SVSD-Garfield Commissioners-ltr.wpd LEAVENWORTH & TESTER, P.C. Planning and Zoning Commission Garfield County Building & Planning Department Page 3 March 24, 1999 of the Roaring Fork District WWTP facility are objecting to the concept of connecting the Spring Valley area to the Roaring Fork District's plant on the grounds of infeasibility and interference with service to existing service area customers. See, Letter from James S. Lochhead, Esq. to Don Deford, Esq., on behalf of Sanders Ranch Holdings, LLC, dated March 18, 1999, attached hereto as Exhibit D. In light of the existing approved Service Plan for the Roaring Fork District, the Roaring Fork District is not under any legal obligation whatsoever to extend service to the Spring Valley area. Nor is there any mechanism that can be utilized to "force" the Roaring Fork District to accept service from the Spring Valley area. Furthermore, the Roaring Fork District would be required to amend its service plan to allow for such service, just as the Spring Valley Sanitation District is requesting approval of an Amended Service Plan to significantly expand its service areas. 2. Colorado Department of Public Health and Environment ("CDPHE") Site Application Regulations. The Staff Report references certain policies and requirements of CDPHE regarding site applications. Clearly, it is the policy of the state to "encourage the consolidation of wastewater treatment facilities whenever feasible." C.R.S. §25-8-702(2)(c). Attached hereto as Exhibit E is a copy of a portion the regulations for the site application process promulgated by the CDPHE through the Water Quality Control Commission. The Regulations make it clear that, in evaluating consolidation the factors that need to be examined are more than technical feasibility. Section 22.3(1)(c) provides that the division shall: Encourage the consolidation of wastewater treatment works whenever feasible with consideration for such issues as water conservation, water rights utilization, stream flow, water quality, and economics. First, we would point out that the Amended Service Plan proposes to provide a regional wastewater treatment plant facility for over 12,000 acres in the Spring Valley area, and results in the consolidation of wastewater treatment works for numerous developments. It is important to note that the policy of the State is to encourage consolidation when feasible; it is not a requirement. Moreover, in analyzing consolidation that there are numerous factors to be considered before consolidation is appropriate. As will be demonstrated throughout this letter, these considerations indicate that consolidation with the Roaring Fork District is not appropriate under the circumstances. F:\1999\Letters-Memos\SVSD-Garfield Commissioners-Itr.wpd LEAVENWORTH & TESTER, P.C. Planning and Zoning Commission Garfield County Building & Planning Department Page 4 March 24, 1999 3. History of Examination of Roaring Fork District Alternative. As early as 1995, the Colorado Mountain College District has commenced an independent review of the viability of that alternative. See, Feasibility Study for Colorado Mountain College, Sanitary Sewer Connection to Aspen Glen Regional Wastewater Treatment Plant, prepared by Meurer & Associates, dated October, 1995, attached hereto as Exhibit F. In late 1995, the cost of an 8 -inch interceptor line necessary to connect the facilities to the Roaring Fork District plant was estimated to be $1,685,923. That number obviously has escalated since 1995. As indicated in the Amended Service Plan, following the decision by the District in 1997 that expansion of its secondary area lagoon facilities was inappropriate, and upon the request for service from the owners of the Lake Springs Ranch PUD and the Spring Valley Ranch PUD properties, the District immediately commenced a review and analysis of the treatment facility options available to it. One of these options was an extensive re-examination of the connection to the Roaring Fork District. Dean Gordon, of Schmueser Gordon Meyer, the District's consulting engineer, has also, over the two-year period, addressed the issues associated with the connection of the Spring Valley area to the Roaring Fork District. Mr. Gordon will testify at the hearing concerning this work. Greg Boecker, the President of the District, will also testify to numerous meetings held by the Board of Directors, in conjunction with property owners in the Spring Valley area, regarding this issue. In sum, this issue has been thoroughly analyzed and discussed for at least six years, since the Wastewater Management Study was prepared. At no time has anyone ever concluded that connection of the Spring Valley area to the Roaring Fork District is feasible, either from a timing or economic standpoint. 4. Adequacy of Roaring Fork District Site. The Roaring Fork District's plant site is presently designed to accommodate an ultimate plant capacity of 0.6 m.g.d. as envisioned by that District's service plan. Notwithstanding that design, in other proceedings before Garfield County a preliminary opinion has been rendered that the Roaring Fork District's site might be redesigned to accommodate a plat of approximately 1.0 to 1.2 m.g.d. For purposes of this discussion, we will assume an expanded 1.2 m.g.d. wastewater treatment plant facility could be constructed on the existing site. According to the Roaring Fork District's 1993 Service Plan, the needs of the primary service area will require 0.32 m.g.d. The F:\1999\Letters-Memos\SVSD-Garfield Commissioners-Ir.wpd LEAVENWORTH & TESTER, P.C. Planning and Zoning Commission Garfield County Building & Planning Department Page 5 March 24, 1999 needs of the expanded service area for the Roaring Fork District were assumed in 1993 to be an additional 0.32 m.g.d., for a total of 0.64 m.g.d. These estimates may be low --Louis Meyer, the Roaring Fork District's consulting engineer, estimates that 0.75 m.g.d. is a more appropriate assumption for the ultimate plant capacity. See, Exhibit G, a memorandum from Louis Meyer, P.E. to the Aspen Glen Water and Sanitation District, dated March 16, 1998. As required by state statute, the Spring Valley District's Amended Service Plan (although it contemplates an anticipated density of 1,571 EQR, with a resulting 0.55 m.g.d. plant) provides for the density approved pursuant to the existing Garfield County comprehensive plan, totaling 4,057 EQR, which results in a 1.5 m.g.d. plant. There is simply no way that the Roaring Fork District site can accommodate the potential2.25 m.g.d. needs of the expanded Roaring Fork District's service area (0.75 m.g.d.) and the potential comprehensive plan densities of the Spring Valley area (1.5 m.g.d.). In addition, the Roaring Fork District's site is inadequate for its expanded service area and the more realistic lower density contemplated by the Spring Valley District (for a total Roaring Fork District plant size of 1.3 m.g.d.). Of course, if the line to connect to the Roaring Fork District went down into Cattle Creek (as opposed to down the County Road right-of-way), the potential for further extensions up Cattle Creek clearly exist. Attached hereto as Exhibit H is a Memorandum from Land Design Partnership, dated March 24, 1999, which estimates that the Cattle Creek area, based on comprehensive plan densities, could add an additional 690 units, or an additional 0.24 m.g.d. of need at the Roaring Fork District facility. I believe that the concept of encouraging consolidation should not be pushed to the point of absurdity. 5. The Effect on Water Re -use Within the Spring Valley Area. Although only mentioned briefly in the Amended Service Plan, one of the primary considerations taken into account by the Board of Directors, as well as the other owners within the Spring Valley area, was the availability of effluent from a plant at the CMC site for re -use for irrigation purposes by the property owners. As currently proposed, and depending on the outcome of the ammonia standard at issue, land treatment will not be required and is not proposed as an integral component of the wastewater treatment plant process. However, all of the owners within the Spring Valley area recognize the importance of water re -use to prevent unnecessary demands on the Spring Valley aquifer. Attached hereto as Exhibit I is an engineering letter report prepared by Wright Water Engineers analyzing the water that can be saved due to re -use of effluent from the District's proposed new plant at the CMC site, as opposed to the quantity of water that will be exported from the Spring Valley basin. The report concludes that the amount of water that will be exported from the Spring Valley aquifer as a result of the Roaring Fork F:\1999\Letters-Memos\SVSD-Garfield Commissioners-ltr.wpd LEAVENWORTH & TESTER, P.C. Planning and Zoning Commission Garfield County Building & Planning Department Page 6 March 24, 1999 District option varies between 616 acre-feet and 1,680 acre-feet per year, depending upon the plant size, or between approximately 31,000 and 84,000 acre-feet over a 50 -year period. This quantity compares with the amount of water savings that occurs as a result of effluent re -use within the Spring Valley area under the Amended Service Plan option between 370 and 1,000 acre-feet per year, or 18,500 and 50,400 acre-feet per year. This amount of water is significant and the benefits of water re -use should not be ignored. Again, it is also very important to remember that the CDPHE's regulations regarding a review of site applications specifically provides for consideration of issues of water conservation and stream flow as an integral part of a review of the issue of consolidation of wastewater treatment facilities. We believe that the attached report demonstrates that, from a water conservation and stream flow standpoint, locating the plant as proposed to allow effluent re -use, and preventing an equal quantity of ground water withdrawals, is an important consideration in locating the plant in the Spring Valley area. 6. Economics of Connection to Roaring Fork District. Attached hereto as Exhibit J is information prepared by Dean Gordon analyzing the economic impacts and costs of connection to the Roaring Fork District versus construction of a treatment plant at the CMC site in the Spring Valley area. Mr. Gordon will elaborate on this issue in his testimony in greater detail. 7. Impact on Existing Users. Pursuant to a policy decision made by the Spring Valley District Board of Directors, the cost for service for existing in -District users within the District will be approximately fifty percent (50%) of actual construction costs on a per EQR basis. The difference will be paid for on a pro rata basis by all new taps sold within the District with the money being provided on the front end by the owners of properties proposed for development. This would add approximately $40.00 to each tap sold within the District. The Board's policy is premised upon its perception that the existing users have provided the site for the proposed facility in an existing ongoing District, with corresponding cost savings to all other users. The Board also determined as a matter of policy that all existing users, including the in -District users, would receive the benefit of financing through a low interest revenue loan through the Colorado Water Resources and Power Development Authority ("Water and Power"). Therefore, the existing District users, such as Auburn Ridge Apartments (Bill and Pamela Gibson), Pinon Pines Apartments (Colorado Pinon Pines Ltd.) and the existing lot owners will be able to pay their share of the cost of plant F:\1999\Letters-Memos\SVSD-Garfield Commissioners-Itr.wpd LEAVENWORTH & TESTER, P.C. Planning and Zoning Commission Garfield County Building & Planning Department Page 7 March 24, 1999 construction by a monthly surcharge of approximately $20.00 per month per EQR and $10.00 per month per EQR for the in -district lot owners. In other words, none of the existing users will be required to advance the cost of plant construction up front because of financing. Finally, the owners of properties proposed for development have, for the most part, indicated a willingness to provide such financing in the event the District is unable to provide a Water and Power loan. It is unknown whether a low interest loan will be available from the Water and Power for connection to the Roaring Fork facility. It is my general understanding that Water and Power does not typically finance the payment of tap fees_for connection to another district. Moreover, it is uncertain as to what policy might be adopted, and how it could be financed if it was adopted, regarding the existing lot owners and existing users regarding the increased cost of connection to the Roaring Fork District and how the money for the Roaring Fork District alternative would be provided for initial construction. Therefore, the impact on the existing in -District property owners and existing contract users could be extremely adverse under the connection to the Roaring Fork District alternative. 8. Timing. It is important for Garfield County to understand the immediate need for plant expansion within the Spring Valley area. The entire capacity of the existing facility is in use or reserved by existing lot owners and contract users. Colorado Mountain College has an immediate need for capacity for its constructed dorms. Moreover, the District's existing users within the District's existing service area (i.e., Los Amigos Ranch Partnership and CMC) have both requested the need for additional service in the immediate future. Los Amigos Ranch Partnership has an approved preliminary plat for 170 units which Garfield County mandated be served with central sewer. The owners of the Lake Springs Ranch PUD and Spring Valley Ranch PUD have both requested a desire to have service in the year 2000. The Commission may have read recent news articles concerning the proposed construction by Colorado Animal Rescue, Inc. ("CARE") of a six thousand (6,000) square foot animal shelter facility in the Spring Valley area on property provided by CMC. At this time, the District does not have capacity to allow the connection of this proposed facility to the District's wastewater treatment plant. Therefore, unless the County is willing to allow the facility to be constructed with an individual sewage disposal system ("ISDS"), the construction of the facility will have to be deferred to the year 2000 when the District's wastewater treatment plant is constructed. 9. Compliance With Statutory Criteria of Adequate Service "Within a Reasonable Time and On a Comparable Basis". F:\1999\Letters-Memos\SVSD-Garfield Commissioners-Itr.wpd LEAVENWORTH & TESTER, P.C. Planning and Zoning Commission Garfield County Building & Planning Department Page 8 March 24, 1999 It appears that the provisions of C.R.S. §32-1-203(2.5)(a) provides the basis upon which the staff is recommended denial based upon inadequate analysis of the potential for connection to the Roaring Fork District. This provision provides: "The Board of County Commissioners may disapprove the service plan if evidence satisfactory to the Board of any of the following, at the discretion of the Board, is not presented: a. Adequate service is not or will not be available to the area through the County or other existing municipal or quasi -municipal corporations, including the existing special districts, within a reasonable time and on a comparable basis." (Emphasis added). I would note that this criteria is discretionary and does not require evidence satisfactory on this issue in any event. Nonetheless, we believe that the foregoing information demonstrates that the Roaring Fork District is not a viable alternative for the Spring Valley area. A primary consideration is the criteria that service by an existing district be provided "within a reasonable time and on a comparable basis". First, we do not believe that there are any contributors currently available for this purpose. Therefore, although cost recovery of a portion of the costs of the interceptor line may be available in the future, the entire cost will need to be paid on the front end by users within the Spring Valley area. Even assuming contribution, however, the service is clearly not "on a comparable basis" since the cost per EQR of the District's proposal is $3,548 per EQR, and connection to the Roaring Fork District is $5,165 per EQR, forty-five percent (45% higher than the District's alternative). Moreover, as discussed above, the impact on the existing users of the District's facilities is extremely adverse and hardly "comparable." Finally, we do not believe that service can be provided by the Roaring Fork District within a reasonable period of time. As discussed above, the District's needs for service are immediate. To require connection to the Roaring Fork District would entail significant delays associated with a complete renegotiation of existing agreements between the Spring Valley District and the property owners proposed for inclusion, the amendment of the Roaring Fork District Service Plan, potential easement acquisition, and/or condemnation negotiations with other property owners in the CMC turn-off and/or Cattle Creek (Sanders Ranch) areas, a new Spring Valley Sanitation District Amended Service Plan, etc. F:\1999\Letters-Memos\SVSD-Garfield Commissioners-ltr.wpd LEAVENWORTH & TESTER, P.C.

The purpose of the study was to determine the most feasible wastewater treatment and disposal plan to serve existing and future development in the Lower Roaring Fork Wastewater Planning Area. The method of analysis and format for the study resemble a condensed version of an EPA Facility Plan (201 Plan). The study was initiated at the request of the Colorado Department of Health, whose representatives requested an 'alternatives study' to evaluate all wastewater treatment options for the area prior to providing approval for the Aspen Glen PUD treatment facilities. Included in the report is a description of the planning area, population and wastewater discharge projections, a comprehensive water quality assessment for the area, and a detailed evaluation of regional wastewater plant sites and treatment processes. The report arrived at the following conclusions: 1. The most feasible location for a new regional treatment plant is on a river terrace located approximately 1/2 mile south of the mouth of Cattle Creek, at the north end of the Aspen Glen PUD property. 2. The recommended treatment process is either an oxidation ditch or standard extended aeration process for secondary treatment, followed by sand filters for tertiary treatment. 3. A regional wastewater treatment plant located in the vicinity of WestBank Subdivision is not feasible at this time. Under the present pattern of development, the most appropriate wastewater treatment plan for that area is continued use of ISDS systems, or tying -4/- WATER WORKS AND SEWERAGE FACILITIES • DRAINAGE AND IRRIGATION SYSTEMS • WATER DUALITY STUDIES April 26, 1993 Page 2 into the Glenwood Springs treatment plant as referenced in the Glenwood Springs 201 Plan - Addendum #2. 4. It is not cost effective to connect the Spring Valley/ CMC plant and the Carbondale plants to a regional system at this time. 5. The use of the Glenwood Springs plant to serve the Planning Area is not feasible at this time due to limited capacity of interceptor lines through the City. However, an engineering study has been commissioned by the City to determine feasibility of expanding the interceptor, which could modify this conclusion. All of the above decisions were arrived at by using a Qualitative Evaluation Matrix, in accordance with EPA guidelines. A major deciding factor in the decisions regarding location of the plants and interconnection of existing and future plants was public opinion. WestBank residents strongly opposed a plant near that development. However, WestBank is not unique in this respect. The Lower Roaring Fork Planning Area is made up of a large number of political entities and separate communities, and obtaining a consensus for a regional plan can be difficult. Each entity tends to be primarily concerned with effects on their local environment and on the costs they must carry for the regional system. Chapter 8 provides a summary review of the existing wastewater systems and outlines the selected alternatives and recommendations. For those readers interested in a more concise, condensed version of the proposed wastewater management plan, we refer them to that chapter. We appreciate the opportunity to work with the Aspen Glen Company on this project, and are available to discuss the project with you and representatives of the various political entities and regulatory agencies. Since ely, William D. Hamann, P.E. WDH/sc encl. 6.6 OPTIONS FOR EXISTING NON -REGIONAL WASTEWATER TREATMENT PLANTS 6.6.1 General. The previous sections provided recommendations for the Roaring Fork Valley sub -area; however, that does not address problems at the outlying plants. Of four existing wastewater treatment plants in the planning area, the Spring Valley/CMC and Carbondale treatment plants are the two plants which may need to upgrade and possibly expand its system in the foreseeable future. Because of the plants' location, neither could serve as a regional plant for the rest of the development in the planning area; however, either could be connected into a regional system. A detailed evaluation was made to compare the pros and cons of utilization of the existing plant with connection of the plant and/or existing collection system to a regional system. 6.6.2 Spring Valley WWTP. • Present and Existing Wastewater Loads. No flow records are available for wastewater discharge into the existing plant. Using the data developed in Chapter 3, the existing equivalent population is estimated to be about 506 people (169 equiv. d.u.'s). Future population is estimated to be 1116 people (572 eq. d.u.'s). The following table shows estimated present and future flows for the Spring Valley area: PER CAPITA CRITERIA FLOW Maximum Day 100 gpcd PRESENT. FLOWS FUTURE FLOWS 50,600 gpd 171,600 gpd Connection to Regional System. If the Spring Valley/CMC area is connected to a regional system, the existing plant could either be left in place to provide primary treatment, or raw sewage could be discharged directly down the new outfall lines to the regional system. If the existing plant is kept in place, there would be continued O&M costs, plus a liner would have to be placed in the two earthen basins to prevent groundwater contamination; both could be fairly expensive. Possible advantages to primary treatment are a possible reduction in outfall pipe size, and reduced maintanenance since it would be carrying a clear liquid, and lower final treatment costs. Since these advantages are very problematic, it will be assumed that the outfall line will be standard 8 inch pipeline and the existing plant will be decommissioned and bypassed. There are two alternative routes for an outfall line to connect to a regional system in the Roaring Fork Valley. Option A would extend cross-country down the south valley wall of Cattle Creek to the county road, then west along the county road to the intersection of the county road with State Highway 82. From this point, the sewerline would extend under Highway 82 and the railroad, through existing tunnels or under trestles and across the farmland presently belonging to Unocal. For purposes of this analysis, it will be assumed that the sewerline would tie into Site B1 since that is the recommended site for a regional plant. Although there is approximately 20 feet of elevation drop between the county road and site B1; there are intervening ridges; therefore, it will be assumed that a pump station with force main will be required to prevent deep trenches. The sewerline will also have to be extended across the Roaring Fork River. Option B for the sewerline outfall would extend westward from the existing treatment plant. Because of the terrain, the route is somewhat sinuous: it would follow the existing access road in several locations, but would cut across switchbacks where feasible, to save sewerline length. Comparative quantities for the two options are as follows: ITEM DESCRIPTION 8 in. gravity pipeline 4 ft. diameter manholes 4 in. force main OPTION A 15,500 ft. 52 ea. 2000 ft. OPTION B 14,800 ft. 49 ea. 2000 ft. The sewerline quantities required is approximately the same for both options. Option A, the Cattle Creek route, will be evaluated since it will serve more development, and may possibly be easier to construct due to less rugged terrain. The cost for the intercepter line is shown in Table 6-E. Treatment costs are based on a proportionate share of the treatment plant costs at Plant Site Bi. For this purpose, a typical plant investment fee of $2000 per dwelling unit was assumed. There are 572 equivalent d.u.'s, for a treatment cost of $1,144,000.

If the existing plant is continued in- place, it will have to be upgraded and improved to meet future CDH regulations, and may also have to be expanded to handle flows from future populations. A Service Plan was prepared for the Spring Valley Sanitation District in July 1979 by Wright McLaughlin Engineers. The proposed plan for upgrading the existing plant and estimated costs are based upon the 1979 report which recommended the following two expansions wich are applicable to the present situation: First Phase - Convert existing ponds to aerated lagoons with capacity of 52,000 gpd. Estimated cost - $129,500. (This has been completed; a Site Application was recently filed to add a second percolation pond.) Second Phase - Add an activated sludge plant and expand capacity to 100,000 gpd. Convert existing ponds to a polishing pond and a percolation basin. Provide a system for spray irrigation, a laboratory and a sludge hauling truck. Estimated cost - $278,000. Third Phase - Expands system to 200,000 gpd. Includes secondary clarifier, aerobic digester, spray irrigation system, rapid infiltration basin. Estimated cost -$250,000. An Engineering News Record Cost Construction Index ratio of 2.0 was used to update the 1979 costs to 1992. The estimated cost to expand the plant is as follows: 2.0 x (278,000 + 250,000) = $1,056,000. An estimated cost of $50,000 will be added for the present improvements. Comparative Costs. Unit costs for the two alternatives are as follows: Total Alt. A - Connection to Regional Plant: Interceptor Line $ 623,700 Plant Investment Fee $1,144,000 Total $1,767,700 Alt. B - On -Site System $1,106,000 Conclusions. Upgrading the existing Spring Valley WWTP is considerably less expensive than connection to a regional system, in part because of the considerable length of outfall line required. Also, since growth is slow, the plant will be upgraded in phases, whereas the sewer line is for ultimate development. A complete evaluation of all non -monetary factors which determine ranking of each option is beyond the scope of this report, since it will not affect location of the regional plant. 6.6.3 Options, for Carbondale Wastewater Plant. Estimated Wastewater Flows. At the present time, Carbondale has a population of about 3,000 people, an average daily flow of about 240,000 gpd, and a maximum day flow of about 400,000 gpd. Per capita average daily flow is 80 gpd, and maximum day flow is 130 gpd. The 208 Plan projects population of 3500 people in Carbondale by the year 2005. Adding the Rocky Mountain School equivalent population of 100 would result in a total P.E. of 3600 and a maximum day flow of 468,000 gpd. The 1987 Discharge Permit. states that the rated capacity of the Carbondale plant is 740,000 gpd. Therefore, this figure will be used as the future estimated wastewater discharge from the Town of Carbondale; however, it is probably a conservative number unless substantial unanticipated growth occurs. Options for Connection to Downstream Regional Plant. Since Carbondale has a existing treatment plant, it has available the same two options for connecting to a regional plant as Spring Valley, i.e., 1) decommission the existing plant and discharge raw wastewater downstream, or 2) convert the existing plant to a primary treatment process and discharge primary effluent to the regional plant. Using the same logic as for Spring Valley, it appears more practical to discharge raw wastewater rather than operate the plant. Option A - Connection to Regional System. Design of Outfall Sewer. An outfall sewer would be extended from the existing Carbondale plant to Site B1. The new outfall would tie into the existing town interceptor sewer above the existing treatment plant to avoid a drop in elevation. The new outfall would then continue west along the top of the bluff bordering the Roaring Fork River. It would cross the Crystal River channel on a trestle to avoid a large pump station, and would tie into the Aspen Glen interceptor. Criteria for sewerline diameter was the same as described in Para. 6.4.2. A pipe diameter of 18 inches will be needed to carry the ultimate flow. The total length of the sewerline will be 19,000 feet, of which 12,000 feet will be on Aspen Glen property and 7,000 feet will be additional pipeline. In calculating costs, the incremental difference between a 12 inch pipeline (size needed for Aspen Glen alone) and an 18 inch pipeline for the Aspen Glen part of the interceptor) will be determined. 1 a 1 3 ,,, !,, 3 ASPEN GLEN WATER & SANITATION DISTRICT SERVICE PLAN November, 1993 Prepared by: Schmueser Gordon Meyer, Inc Delaney & Balcomb, P.C. Hanifen-Imhoff, Inc. 9 WASTEWATER UTILITY SYSTEM 1. Regionalization of Wastewater Treatment In its initial zoning application, Aspen Glen Golf Partners, Ltd. proposed constructing a wastewater utility system that would serve the needs of only the Aspen Glen PUD. However, during the land use process both Garfield County and CDOH suggested that any wastewater treatment facility to be constructed to serve the Aspen Glen PUD be designed to serve as a regional wastewater treatment facility, i.e., a facility that can ultimately provide wastewater service to an area larger than the Aspen Glen PUD. At the request of CDOH Aspen Glen commissioned a study entitled "Wastewater Management Study, Lower Roaring Fork Planning Area", (hereinafter Wastewater Management Study) which was completed by West Water Engineering in April of 1993. The purpose of that study was to determine the most cost effective and appropriate wastewater treatment facility for the AGWSD and surrounding area. The Roaring Fork Valley, from Carbondale to Glenwood Springs has been the subject of several reports in the past: • A 303 study entitled, "The Roaring Fork River - Basic Water Quality Management Plan", completed March, 1974. • A 208 plan entitled, "Water Quality Management Plan Regional 11 - Garfield, Mesa, Moffat, Rio Blanco Counties", completed 1979 and updated 1986. • A 201 plan entitled, "Carbondale 201 Plan", completed in 1978. • A 201 plan entitled, "Glenwood 201 Plan", completed in 1976. The Wastewater Management Study reviewed the contents and conclusions of each of those reports during the course of this analysis. The Wastewater Management Study concludes that a site within the Aspen Glen PUD boundary is the most appropriate site for a regional wastewater treatment facility within the study area. The report also identifies a "service area" larger than the Aspen Glen PUD (and hence larger than the initial boundary of the AGWSD) that can be served by a regional wastewater treatment facility located at the site within the Aspen Glen PUD. The "service area" identified in the Wastewater 99- 8 Management Study can generally be described as the Crystal River Ranch presently undeveloped and lying southwesterly of the Aspen Glen PUD; the CoryeIl Ranch, owned by Unocal, which is undeveloped and lies generally to the south of the Aspen Glen PUD; and the Burry property, also undeveloped, lying generally to the east of the Aspen Glen PUD. In addition to the "service area" identified in the Wastewater Management Study, the proposed site for the Aspen Glen Wastewater Treatment Facility has the potential to provide wastewater treatment to an "expanded service area". Such "expanded service area" is generally defined as the presently undeveloped land lying to the north of the Aspen Glen PUD now owned by James L. Rose; the Sanders Ranch, undeveloped and lying to the east of the Aspen Glen PUD presently owned by Unocal; and the developed property lying to the north and east of the Aspen Glen PUD identified as "mid-way" in the Wastewater Management Study and generally being within an approximate one-half mile radius of the southerly intersection of Colorado State Highway 82 and Garfield County Road 154. A map depicting the above described "service area" and "expanded service area" is presented herewith as Figure II-1. Aspen Glen Golf Partners, Ltd. agrees that the Aspen Glen Wastewater Treatment Facility should be envisioned as a regional treatment facility. However, of all the property discussed herein, the only existing development proposal is the Aspen Glen PUD. The remainder of the property is either partially developed with existing operational wastewater treatment systems of some type, or completely undeveloped with no present or foreseeable development plan. The initial boundaries of the AGWSD will therefore only include the Aspen Glen PUD. The proponent also suggests, however, that by this Service Plan, the "service area" of the Wastewater Management Study and the "expanded service area", both as described above and as depicted on Figure II-1, all be identified as "real property capable of being served by the facilities of the District" as that phrase is used in C.R.S. 32-1-401, for purposes of inclusion of real property within a special district. In order to encourage all of the property depicted on Figure II-1 to seek wastewater service from the Aspen Glen Wastewater Treatment Facility, the AGWSD will and does hereby formulate the following annexation policy: 9 3 1 Annexation Policy of Aspen Glen Water and Sanitation District. The property outlined on the map attached hereto as Figure II -1 is hereby identified as real property capable of being served by the facilities of the District as that phrase is used in C.R.S. 32-1-401. Such property includes, without limitation: a. The Rose Property; b. Two parcels of real property owned by Unocal, one lying generally to the east of the Aspen Glen PUD and the other lying generally to the south of the Aspen Glen PUD; and c. The presently developed property in the approximate radius of one- half mile from the southerly intersection of Colorado State Highway 82 and Garfield County Road 154. The foregoing properties, as well as any other property which may be capable of being served by the facilities of the District, are hereby defined as the Service Area of the District. The District encourages any or all of its Service Area to become a part of the District. The addition of territory into a special district is presently regulated by Part 4, Article 1, Title 32 of the Colorado Revised Statutes. Subject to the provisions of said Part, as the same may now exist or hereafter be amended, the District shall grant a petition for inclusion of any of the Service Area properties into the District upon satisfaction of the following: i. The District and the Petitioner for inclusion shall agree upon the number of EQRs which will require service from the District within the property proposed for inclusion. ii. Based upon the agreed number of EQRs, the engineers .of the District, in consultation with the Petitioner, shall make a determination regarding the capacity of the then existing waste water treatment facility to provide service to such number of EQRs. In the event the plant's capacity needs to be expanded, Petitioner shall bear the cost of such necessary plant expansion, subject to the right of cost recovery as set forth herein. In the event that the plant's capacity is adequate to provide service to the number of EQRs, because of plant construction or expansion previously funded by others, the Petitioner shall agree to pay his proportionate cost of the plant capacity available to him. In such event the District shall be obligated to insure that appropriate treatment capacity is available to all parties that have funded plant construction. f iii. The Petitioner for inclusion shall bear the cost of installation of any necessary sewer trunk line from the property seeking inclusion to the AGWWTF provided, however, the District shall bear the expense of installing 10 1 1 3 1 1 1 1 1 1 1 3 1 2 that portion of any sewer trunk line which makes use of the District's easement through the Teller Springs Subdivision. The District may require a Petitioner for inclusion to oversize the trunk line at the time of installation to provide for additional anticipated users to be served by or from such trunk line. The additional cost of oversizing such line shall either be paid for by the District, or paid for by the Petitioner, subject to a cost recovery agreement as set forth herein. iv. Upon satisfaction of the foregoing requirements. the District shall provide service to the number of EQRs previously agreed upon within the property included without the payment to the District of any portion of any tap fee or system improvement fee which is charged by the District and which is attributable to plant expansion or system enlargement; provided, however, the District shall have the ability to enter into contractual agreements with Petitioners who pay for plant or system expansion which generally provide that such Petitioners may recover all or a portion of their expansion costs by designating such costs as "pre -paid tap rights" which such Petitioners may then transfer to the ultimate service users. In the event additional EQRs within such property request service, the District shall only provide service thereto in the event the capacity is available within the system and subject to the District's regularly scheduled system improvement fees. v. In the event a Petitioner for inclusion is required to pay for either plant or trunk line capacity in excess of the number of EQRs to be served on his property, the District and such Petitioner may enter into a cost recovery agreement which provides that any future user who will make use of either the excess plant capacity or oversized trunk line paid for by such Petitioner shall pay a fee to such Petitioner for each EQR seeking such service. The amount of the fee shall be determined on an EQR basis, by dividing the cost of the excess plant capacity and/or oversized trunk line paid for by such Petitioner by the total number of EQRs capable of being served by the subject excess plant capacity and/or oversized trunk line. The Petitioner's right to recover costs as set forth in such Agreement shall be limited to the total amount he has paid for plant or line capacity in excess of the needs of the property originally included within the District by such Petitioner. vi. The District shall require that all internal collection lines within an area sought to be included in the District shall be installed to the satisfaction of and dedicated to the District. vii. Any property included within the District pursuant to this annexation policy shall, from and after the time of inclusion, be subject to all of the District's fees and charges, including applicable property taxes, except as expressly set forth herein. vies. As part of the Annexation Agreement, the District. shall, upon request of the Petitioner, agree to forebear from objecting to any water right 11 ....... .• ••••• •••cirl • • • if a ••• N • z .SCALE: /" = 2000' LEGEND ASPEN GLEN 6600^ WASTE -WATER MANAGEMENT wrAlrally:".-Av:"21 STUDY SERV/CE AREA EXTENDED SERV/CE MI MINI INN MI IN AREA 0 lo 1,1\ —•.-yr4-3#1/-')r A JOHN A.

P.O. Drawer 2030 Glenwood Springs, CO 81602 Dear Lee: Telephone: 970.945.6546 Facsimile: 970.945.9769 February 25, 1999 OF COUNSEL: KENNETH BALCOMB Re: Roaring Fork Water & Sanitation District/Spring Valley Sanitation District I am writing on behalf of the Roaring Fork Water & Sanitation District (the "Roaring Fork District"), formerly known as the Aspen Glen Water & Sanitation District. As you will recall, by letter dated October 19, 1998, Greg Hall of your office inquired whether or not the Roaring Fork District would be willing and able to provide wastewater treatment services to the present and future users of the Spring Valley Sanitation District. Since that letter, the Board of Directors of the Roaring Fork District has had a number of discussions on this issue, most particularly at its meetings on October 28, 1998 and November 25, 1998. Throughout these discussions, it has been the unanimous and consistent conclusion of the Board that the Roaring Fork District is unable to provide sewer service to the Spring Valley area. I have advised you and the Spring Valley Sanitation District Board of this conclusion on a number of occasions, but, as a result of a request by Garfield County, you have now asked that I offer a written explanation of the Roaring Fork District's decision. The Service Plan for the Roaring Fork District was approved by Garfield County after a lengthy series of public hearings on January 31, 1994 by Resolution No. 94-008. A major part of the foundation of the Service Plan was a study commissioned by Aspen Glen Golf Partners at the request of the Colorado Department ofHealth entitled "Wastewater Management Study, Lower Roaring Fork Planning Area" (the "Wastewater Management Study"). The purpose of the Wastewater Management Study was to determine the most cost effective and appropriate wastewater treatment facility for the proposed Aspen Glen development and the surrounding area. The Wastewater Management Study, and hence the Service Plan, identified a "Service Area" and an "Expanded Service Area" which could potentially receive wastewater treatment service from a facility located at the proposed site of the Roaring Fork District's facility. The Wastewater Management Study also considered the Spring Valley area and concluded that it would not be appropriate for the Roaring Fork District and its proposed site to provide service to the Spring Valley area because it would be prohibitively expensive and the proposed site would be inadequate. The Wastewater Management Study concluded: "If it is necessary for Spring Valley to upgrade their system, the most feasible approach will be to provide improvements to the existing treatment plant at Spring Valley rather than extend an interceptor line to the nearest regional treatment plant." The Service Plan thus proposed that the Roaring Fork District be conveyed a site of approximately 6.5 acres, which would be large enough to accommodate a tertiary treatment facility which could provide service to the Roaring Fork District's Service Area and Expanded Service Area as identified in the Service Plan. As submitted, the initial draft of the Service Plan proposed that such facility would be constructed to a maximum capacity of 320,000 gallons per day. However, during the public hearing process, and as a result of Out -of -District Service Contracts approved by Garfield County as part of the Service Plan, the proposed Service Plan was amended to provide that the Roaring Fork District's site would be the site for a regionalized wastewater treatment plant which would have an ultimate treatment capacity of 600,000 gallons per day, the estimated total capacity need for the Roaring Fork District's Service Area and Expanded Service Area. Consistent with the terms and conditions of the approved Service Plan, and the underlying Wastewater Management Study, the Roaring Fork District now owns a site of 6.5 acres. It owns and operates a tertiary wastewater treatment plant having a constructed and operating capacity of 107,000 gallons per day, with preliminary designs for expansion to an ultimate capacity of 600,000 gallons per day. The Roaring Fork District believes that if it were to provide service to the Spring Valley area it would be unable to provide service to its own Service Area and Expanded Service Area as identified in its Service Plan. The District has concluded that its first responsibility is to satisfy the present and future needs of property owners within its own Service Area and Expanded Service Area. Its treatment plant and site are designed to enable the District to satisfy that responsibility. The Roaring Fork District has thus concluded that it is not able to provide wastewater treatment service to the Spring Valley area. A portion of the minutes from the Roaring Fork District's Board meeting of October 28, 1998 setting forth this conclusion is attached. Please do not hesitate to contact me if you have any further questions in regard to this matter. Very truly yours, BALCOMB & GREEN, P.C.

SUITE 900 WASHINGTON, D.C. 20004 (202) 434-8377 FAX (202) 393-7864 I am writing on behalf of Sanders Ranch Holdings, LLC, owners of the Sanders Ranch located west of Highway 82 at Cattle Creek. I understand that the Spring Valley Sanitation District has filed for an amendment to its service plan, and one of the issues that has come up is whether or not the Roaring Fork Water & Sanitation District (formerly the Aspen Glen Water & Sanitation District) would be willing and able to provide wastewater treatment services to the present and future users of the Spring Valley Sanitation District. I understand that the Roaring Fork District has formally advised the Spring Valley District that it is not able to provide such service, in part because of the commitments it has to provide service to properties within its service area and expanded service area. I am writing to support the position of the Roaring Fork District in this regard. I request that this letter be made a part of the record in the County's consideration of the service plan amendment for the Spring Valley Sanitation District. The Sanders Ranch property is included in the expanded service area of the Roaring Fork District, as identified in the service plan for the District approved by Garfield County. In addition, the Roaring Fork District is under a contractual obligation to provide wastewater treatment services to the Sanders Ranch property, in accordance with the Out -of -District Service Agreement which is also part of the approved service plan. The ultimate capacity of the Roaring Fork District plant was calculated specifically in contemplation of service to Sanders Ranch in accordance with the agreement. Sanders Ranch has the right to service from and access to that capacity. No service may be provided by the Roaring Fork District, and no obligation may be imposed by Garfield County or the state of Colorado by virtue of service plan or other approvals, which would impair the contractual rights of Sanders Ranch for service. It would be inappropriate, and Sanders Ranch r. 4 Mr. Don DeFord March 18, 1999 Page 2 would oppose, any attempt by the County or the state to deny service plan amendments, or deny or condition approvals sought by the Spring Valley Sanitation District that would impair the contractual rights of Sanders Ranch. In short, any service by the Roaring Fork District to Spring Valley would be subject and subordinate to the rights of Sanders Ranch. The Roaring Fork District's position, and the service plan for the Roaring Fork District make clear, that capacity does not exist to provide such service. If you have any questions concerning the position of Sanders Ranch, please give me a call. cc: George Hanlon Larry Green Lee Leavenworth Very truly yours, BROWNSTEIN HYATT FARBER & STRICKLAND, P.C.

EXECUTIVE SUMMARY This Feasibility Study has been prepared for the Colorado Mountain College by Meurer & Associates, Inc., to identify the pertinent issues relative to connecting to the Aspenglen Regional Wastewater Treatment Plant. The issues, information and costs for the sewer connection are as follows: Aspenglen Regional Wastewater Treatment Plant (ARWWTP) Phase I of the ARWWTP is scheduled to be complete in January, 1996, and will initially serve the Aspenglen Development. The defined service area for the ARWWTP does not include the Colorado Mountain College (CMC). However, since the ARWWTP is a regional plant, users outside the service area will not be excluded from service if the Plant has the capacity to serve them. Service to CMC will require that the service area be amended to include the College. CMC will need to work with Aspenglen to amend the service area. Tap fees for connection to the Plant will need to be negotiated. The capacity of Phase I will be 0.107 million gallons per day (mgd) which can serve approximately 305 equivalent single family residential units (EQR's). Ultimate Capacity of the ARWWTP can be as high as 0.6 mgd (1,715 EQR's). The ARWWTP has the capacity to serve CMC if CMC connects to the Plant prior to the Plant reaching its ultimate capacity. CMC needs to connect to the ARWWTP before it reaches ultimate capacity. Sewer Line Alignment The general alignment of the sewer line extends from the existing wastewater lagoons south to County Road No. 113, then west in the County Road to approximately one half mile east of Highway 82, then southwesterly to Cattle Creek and west to Highway 82. From this point, the sewer line extends under Highway 82 and the railroad and across the Union Oil Company of California (Unocal) Property, then across the Roaring Fork River to the ARWWTP. A conceptual plan of the sewer line is in the Appendices. The total length of the sewer line is approximately 16,050 feet. The size of the sewer line is 8 -inches in diameter. A lift station, located east of Highway 82, is needed to pump sewage across Highway 82 and the railroad tracks. The force main from the lift station is 6 -inches in diameter and extends under the Highway and the railroad tracks. Easements are needed where the sewer line is within private property and Bureau of Land Management Property. Acquisition of easements from property owners will require negotiations with landowners. Depending on the landowner, easement acquisition can be time consuming. The Bureau of Land Management estimates that obtaining an easement from them can take as long as one year. Wetlands Wetlands exist in the vicinity of sewer line alignment in three locations: along a portion of the unnamed drainage channel above County Road No. 1 13, along the Cattle Creek channel and the wet meadow north of Cattle Creek, and along the Roaring Fork River. Wetland impacts for this sewer line can be permitted under Section 404 Nationwide Permit #12. In areas where wetlands are disturbed, the wetlands topsoil and vegetation need to be replaced following construction. The project schedule should not be impacted by wetland permitting requirements. Future Users The alignment of the sewer line is such that other areas will have the ability to connect to the sewer line and be served by the ARWWTP. Potential future users identified along the alignment are as follows: M • The Spring Valley Sanitation District (SVSD), which includes the Los Amigos Subdivision, Los Amigos Ranch, the Auburn Ridge Apartments and a future elementary school. The SVSD is identified as a future user because the existing lagoons may not be permitted by the CDOH if the SVSD can be served by the ARWWTP. • The Cattle Creek basin, which includes the properties along County Road No. 113. • Unocal Property — Development on the Unocal property will be served by the ARWWTP. The Unocal property is within the service area of the ARWWTP. Construction • Construction methods and requirements will vary along the alignment of the sewer line. The topography along the alignment includes steep slopes, rock, wetlands, river and highway crossings, and pavement removal and replacement. Each of these conditions present additional costs for construction of the sewer line. Some of the construction methods and requirements that will add cost to the project consist of the following: rock excavation may have to be accomplished by blasting; steep slopes present difficulties for trenching and pipe installation; traffic control on County Road No. 113 will require full-time flaggers during construction; creek crossings need to be installed in a steel casing pipe for erosion protection; highway and railroad crossings need to be bored and a steel casing pipe inserted; wetland areas need to be returned to there original condition following construction. Estimate of Probable Costs The estimate of probable cost includes estimates for connection to the ARWWTP, construction, engineering, and easement acquisition. These estimates are based on the available information at the time the Study was prepared. The estimate of probable costs are summarized below. Connection to ARWWTP (not including tap fee) $506,000 Construction $1,466,000 Engineering $220,000 Easement Acquisition $36,000 Estimate of Probable Costs for Project $2,228,000 i PRELIMINARY ESTIMATE OF PROBABLE COST FOR CONSTRUCTION AND ENGINEERING Project: Colorado Mountain College Sanitary Sewer Connection to the ARWWTP Prepared By: GSS Item No. Item Description Approx.

RE: Ultimate Wastewater Treatment Plant Capacity At the last Board meeting, f was directed to determine the ultimate flow capacity in gallons per day (gpd) of the current Aspen Glen Water & Sanitation District treatment site. This memo addresses that issue. This' memo will first discuss the historical background that established the capacity of the wastewater treatment facility. Secondly, 1 will address the ultimate available capacity for this site. By way of history, the document which best summarizes the planning that went into the WWTF site is the Service Plan. The Service Plan formalized the terms and conditions and conditions of the formation of the District, Specifically, I am attaching pages 8 and 9 of the Services Plan which discusses the service area for the District. The Wastewater Management Study Service Area defined in the Service Plan posed flow contributions of approximately 320,000 gpd. The Service Plan did not specifically discuss the proposed flow contribution from the extended service area. Upon completion of the Service Plan during the negotiation stage with Unocal, a figure of 600,000 gpd for the extended service area was used. Recently,,the District has received requests from the Rose Ranch and Sanders Ranch for wastewater service. Both the Rose Ranch and Sanders Ranch are included in the extended service area and are covered by an Out -of -District Sewer Service Agreement between the District and what was formerly the Union 011 Company. The enclosed table shows the proposed EQR's for Aspen Glen, the remainder of the primary service area, which included the Burry property, the Coryell Ranch and the Crystal River Ranch along with the proposed EQR's for Cattle Creek Landing (Sanders Ranch) and the Rose Ranch. This total 2075 EQR's. 2075 EQR's, using the state criteria of 100 gpcd and 3.5 persons per unit, results in a flow of 726,250 gpd. What i3 the ultimate capacity in flow far the District's current site? Attached is the plat showirg the dedicated site to the Water & Sanitation District. That site totals 6.06 acres.

Drawer 2030 Glenwood Springs, Colorado 81601 RE: Spring Val:cy: Sanitation District Service Plan Amendment Dear Lee: At the request of our client, Aspen Springs Ranch, Inc., this letter outlines a significant water resources issue related to the proposed Spring Valley Sanitation District (SVSD) Service Plan Amendment. The issue for the Spring Valley basin is preserving and re -using water resources within the basin versus exporting water from the basin in the form of wastewater to be treated at the Roaring Fork Water and Sanitation District treatment plant located adjacent to the Roaring Fork River. It is our understanding that the currently proposed development projections for the Spring Valley area would require a 0.55 million gallons per day (mgd) wastewater treatment facility and the current Garfield Comprehensive Plan projections for ultimate buildout would require a 1.5 mgd facility. The export of water and savings of in -basin water is summarized in the table below. The values expressed are in acre-feet and show the impacts and savings under both the proposed anticipated density (the 0.55 mgd plant) and the existing comprehensive plan density (1.5 mgd plant). The savings is related to water re -used for irrigation during the summer and a portion of the winter discharge that would recharge the Spring Valley aquifer.

The 0.55 mgd facility will irrigate approximately 150 acres and the 1.5 mgd facility could irrigate approximately 420 acres based on a sprinkler system application of 2 acre-feet per acre. The Spring Valley Ranch P.U.D. alone proposes approximately 400 acres of golf course and open space irrigation and it is the developer's intent to re -use effluent from the SVSD. Additionally, it is conservatively estimated that 20 percent of the winter effluent discharge would infiltrate and recharge the Spring Valley aquifer and 80 percent would flow down Red Canyon to the Roaring Fork River.

SZROT, County Engineer To: File Re: Spring Valley, March 24th Leavenworth Document 1 have reviewed the March 24th, 1999 letter with attachments (Exhibits A -J) and have the following comments. This document strongly presented reasons why Spring Valley should not be required to attach to the Roaring Fork waste treatment facility. This argument, however, only addresses one of four possible scenarios to treat wastewater from Spring Valley future developments. As I presented before the Planning and Zoning Board meeting on March 24th, there are four possible solutions to treat waste from the present and future Spring Valley community: 1) Don't treat waste in Spring Valley, pipe all discharges directly to another facility — such as the Roaring Fork facility 2) Treat waste in Spring Valley and run a pipe for discharge directly to the Roaring Fork River to get the dilution capacity to accommodate this discharge flow. 3) Treat waste in Spring Valley and discharge to the Landis Creek tributary. 4) Treat waste in Spring Valley and utilize land application/irrigation for discharging. The State of Colorado performed a discharge calculation on the Landis Creek Tributary (Option 3) and found that ammonia standards for any plant discharge would have to be below 1 mg/I most of the year. Modern plant technology will get ammonia discharge to at or above 1 mg/I — so this option might not be technically feasible under current regulations. In addition, I question the ultimate discharge point of Landis Creek — will this also take treated discharge out of the Spring Valley area? V- 109 8th Street, Suite 300, Glenwood Springs, CO 81601-3363 (970) 945-5004 FAX (970) 945-7785 Options 1 & 2 were opposed by Spring Valley as it takes discharge water out of the Spring Valley area. While this is true, these solutions are technically feasible, however, economic and political issues might be driving factors. Option 4, land use, is technically feasible and retains treated discharge in the Spring Valley area. I would support any option that complies with discharge regulations and best industry practices. I also believe that any one of the four options would comply with the spirit of "regionalized" waste treatment. With comprehensive plan build- out for the Spring Valley area at around 1,500 houses, one could easily look upon this area as its own region. Contrary to this, State policy supports connection of new development to existing waste treatment facilities within 5 miles of each other. At the Planning and Zoning meeting, no technology or designs were presented to assure the Landis Creek discharge option would even work, and no plans or storage locations were shown for the land use option. The presenters made clear their objections to out -of -the -area discharge yet did not have the planning or technical information to support in -area concepts. I still believe that three of the four options would be feasible from a technical and regulatory viewpoint at the present time (the Landis Creek option excluded), however, until the presenters provide a detailed plan for the in -area options, I cannot support approval of the Amended Service Plan. A point of notation in Section 5 — Initially it is stated that "land treatment will not be required and is not proposed as an integral component of the wastewater treatment plant process". This is followed one paragraph later by "the benefits of water re -use should not be ignored". If the presenters are so strongly in favor of in -area discharge, I hope that they so state this and then support this option with appropriate resources and technology. Sherman & Howard L.L.c. Board of County Commissioners Garfield County 109 8th Street, Suite 200 Glenwood Springs, Colorado 81601 ATTORNEYS & COUNSELORS AT LAW 633 SEVENTEENTH STREET, SUITE 3000 DENVER, COLORADO 80202 TELEPHONE 303 297-2900 FAX 303 298-0940 OFFICES IN: COLORADO SPRINGS RENO • LAS VEGAS February 23, 1999 Re: Spring Valley Sanitation District Amended Service Plan Ladies and Gentlemen: FiTif‘-cf1999 A qAA We are special counsel to the County with respect to the review of the above - referenced Service Plan amendment, and this is in response to a request from the County Attorney's office to review and comment on the financial provisions in such amendment. It is our understanding that the District is an existing Title 32 sanitation district, and that it is proposing an amendment to its Service Plan to deal with projected new development. The section that we examined had to do only with the new debt or other financial obligations which the District could incur under the amendment. I. GENERAL STATE LAW RESTRICTIONS First, it should be pointed out that the financial section does not limit in any material way any kind of obligation the District could issue, whether that obligation is payable from ad valorem taxes or system revenues. Thus, the only limitation which would apply would be those under existing state law. Whether this is appropriate or not depends upon how the County views this matter. As I discussed with the County Attorney, it has become somewhat common to place restrictions in the Service Plan upon the issuance of obligations by a special district payable from an ad valorem mill levy. On the other hand, Districts will ordinarily try to resist such limitations on the theory that state law already puts restrictions on their abilities to incur financial obligations (e.g., TABOR, the Special District Act itself, and the original Article XI, Section 6, Colorado Constitution limitations). It may also be true that limitations in the Service Plan on that ability will result in increased borrowing costs. Consequently, the first suggestion I have is that the County evaluate whether it feels any restrictions are necessary or appropriate in this case. With respect to limitations inherent in state law now, the following is an excerpt from the portion of the Special District Act (Section 32-1-1101, C.R.S.) which places restrictions on the issuance of tax -supported bonds: "(6) (a) The total principal amount of general obligation debt of a special Sherman & Howard L.L.c. Garfield County, Colorado February 23, 1999 Page 2 district issued pursuant to subsection (2) of this section, which debt is issued on or after July 1, 1991, shall not at the time of issuance exceed the greater of two million dollars or fifty percent of the valuation for assessment of the taxable property in the special district, as certified by the assessor, except for debt which is: (I) Rated in one of the four highest investment grade rating categories by one or more nationally recognized organizations which regularly rate such obligations; (II) Determined by the board of any special district in which infrastructure is in place to be necessary to construct or otherwise provide additional improvements specifically ordered by a federal or state regulatory agency to bring the district into compliance with applicable federal or state laws or regulations for the protection of the public health or the environment if the proceeds raised as a result of such issue are limited solely to the direct and indirect costs of the construction or improvements mandated and are used solely for those purposes; (III) Secured as to the payment of the principal and interest on the debt by a letter of credit, line of credit, or other credit enhancement, any of which must be irrevocable and unconditional, issued by a depository institution: (A) With a net worth of not less than ten million dollars in excess of the obligation created by the issuance of the letter of credit, line of credit, or other credit enhancement; (B) With the minimum regulatory capital as defined by the primary regulator of such depository institution to meet such obligation; and (C) Where the obligation does not exceed ten percent of the total capital and surplus of the depository institution, as those terms are defined by the primary regulator of such depository institution; or (IV) Issued to financial institutions or institutional investors. (b) Nothing in this title shall prohibit a special district from issuing general obligation debt or other obligations which are either payable from a limited debt service mill levy, which mill levy shall not exceed fifty mills, or which are refundings or restructurings of outstanding obligations, or which are obligations issued pursuant to part 14 of this article." The primary restriction is in 6(a), which basically requires that the assessed valuation of the District be twice the principal amount of any bonds, except for a de minimus exception of $2,000,000. Note that limited mill levy obligations payable from a mill levy of 50 or less are permitted by 6(b) regardless of amount (as are refundings which shouldn't be relevant here, since the District has no outstanding debt). If the County feels that such restrictions are sufficient, then it could (a) rely upon the state law restrictions, or (b) place such state law restrictions in the amended Service Plan against the event that the above statute is changed in the future. Obviously, the County could also choose to insert additional restrictions. For example, I have seen Service Plans which do not permit the $2,000,000 de minimus exception on Sherman & Howard L.L.c. Garfield County, Colorado February 23, 1999 Page 3 the theory that even that amount of debt might cause the mill levy to become too high. With respect to revenue obligations (i.e., obligations not payable from ad valorem taxes) Title 32 does not place restrictions upon such obligations. However, the Municipal Bond Supervision Act does restrict those obligations, as well as obligations payable from taxes, and thus the County could logically conclude that sufficient controls exist with respect to any type of such obligation. The Municipal Bond Supervision Act provides that no obligations can be issued without an exemption or registration. There has not to date been any registrations of any obligations, and the conventional wisdom is that there probably will not be, because the exemption provisions describe almost every transaction which could be marketed in any event. The exemptions are as follows: "(b) Any issue of general obligation bonds where the total obligation represented by the issue together with any other general obligation of the district does not at the time of issuance exceed the greater of two million dollars or fifty percent of the valuation for assessment of the taxable property in the district as certified by the assessor; (c) Any issue of bonds that is rated in one of its four highest rating categories by one or more nationally recognized organizations which regularly rate such obligations; (d) Any issue of bonds by a district in which infrastructure is in place which has been determined by the board of such district to be necessary to construct or otherwise provide additional improvements specifically ordered by a federal or state regulatory agency to bring such district into compliance with applicable federal or state laws or regulations for the protection of the public health or the environment if the proceeds raised as a result of such issue are limited solely to the direct and indirect costs of the construction or improvements mandated and are used solely for those purposes; (e) Any issue of bonds secured as to the payment of the principal and interest on the debt by a letter of credit, line of credit, or other credit enhancement, any of which must be irrevocable and unconditional, issued by a depository institution: (I) With a net worth of not less than ten million dollars in excess of the obligation created by the issuance of the letter of credit, line of credit, or other credit enhancement; (II) With the minimum regulatory capital as defined by the primary regulator of such depository institution to meet such obligation; and (III) Where the obligation does not exceed ten percent of the total capital and surplus of the depository institution, as those terms are defined by the primary regulator of such depository institution; (f) Any issue of bonds insured as to the payment of the principal and interest on the debt by a policy of insurance issued by an insurance company authorized to Sherman & Howard L.L.c. Garfield County, Colorado February 23, 1999 Page 4 do business as an insurance company in this state and authorized for such risk by the insurance commissioner appointed pursuant to section 10-1-104, C.R.S.; (g) Any issue of bonds not involving a public offering made exclusively to accredited investors, as that term is defined under sections 3(b) and (4)(2) of the federal "Securities Act of 1933" by regulation adopted thereunder by the securities and exchange commission; (h) Any issue of bonds made pursuant to an order of a court of competent j urisdiction; (i) Any issue of bonds by a district which has principal amounts payable from moneys other than the proceeds of an ad valorem tax, where the total of such obligations represented by the issue, together with other such bonds of the district, does not at the time of the issuance exceed two million dollars; (j) Any issue of bonds of the district issued to the Colorado water resources and power development authority which evidences a loan from said authority to the district; and (k) Any issue of bonds by a district that contains territory subject to an intergovernmental annexation agreement between the city and county of Denver and Adams county dated April 21, 1988, made pursuant to section 30-6-109.5, C.R.S." Again, the above provisions apply to both general obligations and revenue obligations, and you will notice certain similarities between the limitations in this statute and those in the Title 32 statute. Again, if the County determines that these restrictions are sufficient and that the chances that they will be changed later is slight, it could logically determine that no further restrictions need to be placed in the Service Plan amendment. II. POSSIBLE ADDITIONS TO THE SERVICE PLAN In the event the County determines that there is a risk that an inordinate amount of bonds could be issued by the District, and wishes to restrict those issuances, I have prepared the following provisions which could be inserted into the Service Plan. Similar provisions have been included in various other service plans on which I have worked in the past, and while they do place material restrictions upon the ability of the District to issue obligations, they are also something which should not unduly limit the District or make its obligations unmarketable. In most instances, they are simply a restatement of the above laws with certain changes (such as the removal of the $2,000,000 de minimus exception), and thus there would be no danger that future changes in those laws would unduly expand the District's authority to issue obligations. FINANCIAL OBLIGATIONS The District may authorize, issue, sell, and deliver such bonds, notes, contracts, reimbursement agreements, or other obligations evidencing or securing a Sherman & Howard L.L.c. Garfield County, Colorado February 23, 1999 Page 5 borrowing (collectively, "Bonds") as are permitted by law; provided that, without the prior written consent of the County, the following limitations shall apply: 1. All Bonds, regardless of whether the District has promised to impose an ad valorem mill levy for their payment, shall be exempt from registration under the Colorado Municipal Bond Supervision Act, or shall be registered under such Act. 2. The principal amount of any issue of Bonds for the payment of which the District promises to impose an ad valorem property tax ("General Obligation Bonds"), together with any other outstanding issue of General Obligation Bonds of the District, may not at the time of issuance exceed fifty percent (50%) of the valuation for assessment of the taxable property in the District, as certified by the assessor, except that the foregoing shall not apply to any of the following issues: (a) an issue of General Obligation Bonds for the payment of which the District has covenanted to impose a maximum mill levy of not more than 50 mills (a mill being equal to 1/10 of 1¢) per annum; provided that, such General Obligation Bonds may also provide that in the event the method of calculating assessed valuation is changed after the date of approval of this Service Plan by any change in law, change in method of calculation, or change in the percentage of actual valuation used to determine assessed valuation, the 50 mill levy limitation herein provided may be increased or decreased to reflect such changes, such increases or decreases to be determined by the Board in good faith (such determination to be binding and final) so that to the extent possible, the actual tax revenues generated by the mill levy, as adjusted, are neither diminished nor enhanced as a result of such changes; (b) an issue of General Obligation Bonds that is rated in one of the four highest rating categories by one or more nationally recognized organizations which regularly rate such obligations; (c) an issue of General Obligation Bonds secured as to the payment of the principal and interest by an irrevocable and unconditional letter of credit, line of credit, or other credit enhancement issued by a depository institution qualified as defined in section 11-59-110(1)(e), C.R.S.; (d) an issue of General Obligation Bonds insured as to payment of the principal and interest by a policy of insurance issued by an insurance company qualified as defined in section 11-59-110(1)(f), C.R.S. -1 9 Sherman & Howard L.L.c. Garfield County, Colorado February 23, 1999 Page 6 (e) an issue of General Obligation Bonds not involving a public offering made exclusively to "accredited investors" as defined under Regulation D promulgated by the federal Securities and Exchange Commission; (f) an issue of General Obligation Bonds made pursuant to an order of a court of competent jurisdiction; (g) an issue of General Obligation Bonds issued to the Colorado Water Resources and Power Development Authority which evidences a loan from said authority to the District; or (h) an issue of General Obligation Bonds which are originally issued in denominations of not less than $500,000 each, in integral multiples above $500,000 of not less than $1,000 each. As you can see, the above restrictions eliminate the $2,000,000 exception discussed above, and also remove some of the other exemptions in the statutes that counties have objected to in the past on transactions I have worked on. At the same time, these provisions allow the District to do typical issues which have adequate security or which have other protections for the taxpayers (such as private placements to accredited investors, who are presumably more able to bear the risk of an investment). It should be noted that the typical exemption for issues sold to the Colorado Water and Power Authority is still present in the above formulation. I have discussed this with the County Attorney, and this financing program is one which is often used by issuers to obtain a lower interest rate since the program offered by the Authority basically uses federal money to secure the obligations. The Authority itself has a stringent evaluation program to make sure the issuer is able to repay the obligations, and thus both the Special District Act and the Municipal Bond Supervision Act contain exemptions for such obligations. III. CONCLUSION It is up to the County whether it feels in this circumstance that the normal state law restrictions should be relied upon (with the possibility that such statutes could be changed in the future) or whether a version of those restrictions should be placed in the Service Plan, thus insulating the County from changes in law and allowing it to make specific changes in those statutes. For Districts for which there is little possibility that it will issue more obligations than it can reasonably pay, some additional restrictions in the Service Plan are appropriate. The above suggestions are based upon the presumption that this District does require such provisions, which may or may not Sherman & Howard L.L.C. Garfield County, Colorado February 23, 1999 Page 7 be the case. In the end, it is a judgment call by the County based upon all the facts and circumstances. Sincerely, SHERMAN & HOWARD L.L.C. Blake T. Jordan w ee 61.641./Ty Point Sources in Garfield County Municipal Point Sources Municipally owned wastewater facilities are in generally good condition in Garfield County. During the late 1970s and through the early 1980s concern for projected growth emanating from the energy industry led to expansion or construction of new wastewater facilities in most municipalities. As a result most wastewater facilities are fairly new and in good operating condition. The following municipalities have completed construction for new facilities in the past five years: Glenwood Springs, New Castle, Silt, Rifle, and Rifle South Metropolitan District. The Town of Parachute receives treatment through the Battlement Mesa Incorporated facility which has also been constructed in the past five years. Adequate capacity for treatment of future growth exists in all of these facilities. S'''''Th The most critical municipal point source needs in Garfield County relate to planning needs for the Spring Valley area. This area, to the southeast of Glenwood Springs, has several proposed developments and sanitation districts. The Lake Valley Sanitation District and the Landis Sanitation District should work in conjunction with Garfield County, and other local developers to determine the scope of development concerns, and the best means of sewage treatment and disposal in the Spring Valley area. This planning effort should analyze populations, consolidation of facilities and treatment requirements for the Spring Valley area. This plan recommends that facility siting efforts should be delayed, and any site approvals withheld until such an analysis and study is completed. Non -municipal Point Sources. in Garfield County Currently non -municipal point sources do not present a threat to water quality in Garfield County. The Battlement Mesa Incorporated facility, which serves the Town of Parachute, as well as the Battlement Mesa development, is currently operating a lagoon treatment facility rather than the activated sludge treatment facility constructed in 1982. This system is much less complicated and less expensive to operate than the mechanical facility. The H Lazy F Mobile Home Park facility has experienced some problems in the past; improved operations have solved these problems. This facility is also located in the bottom of the drainage that both the Colorado Mountain College facility and proposed Spring Valley developments are located within. Inclusion of this facility in any study efforts for the Spring Valley area would be wise. r.'

The Division cannot support points #1 and #4 of your memo for the following reasons. In your memorandum, you stated that the preliminary effluent limits which were presented in the Division's letter of February 4, 1999 were incorrect and would not have to be met. Although the Division is willing to refine preliminary limits based on new information, such as a site-specific analysis of expected effluent pH values for the proposed treatment facility, the limits presented in our letter are within the range of limits to be expected for a discharge to Landis Creek under its current classification as a class 1 cold water aquatic life strewn. We agree that the limits could change once a use attainability analysis (UAA) is completed, however, your statement regarding preliminary calculations of ammonia limits for a class 2 designation is not correct. If the UAA is completed, and it supports a class 2 designation for Landis Creek, and if the Water Quality Control Commission (WQCC) agrees to downgrade the segment to a class 2 designation without a numeric standard for unionized ammonia, then no limit for ammonia would be required. If, on the other hand, a UAA does not support redesignation or the WQCC decides to change the designation to class 2 but leaves the current numeric standards in place, then the limits will be substantially the same as those presented in our February 4, 1999 letter. In summary, unless a site-specific pH analysis is completed or the WQCC revises the classification for Landis Creek and removes the numeric standard for unionized ammonia, preliminary effluent limits for the proposed Spring Valley wastewater treatment facility will not be substantially revised.

Mehan Date: April 22, 1999 Re: Summary of Meeting with Colorado Department of Public Health and Environment on April 21, 1999 This memorandum summarizes the meeting held with the Colorado Department of Public Health and Environment (CDPRE) on April 21, 1999. The purpose of the meeting was to discuss: 1) the implications of a change in the Class 1, Cold Water aquatic life use designation. and 2) the proposed work plan for the use attainability study (UAS). In attendance at the meeting were Dennis Anderson and Saran Johnson from the CDPHE, Dave Moon from the U.S. Environmental Protection Agency (EPA), and David Mehan from Wright Water Engineers, Inc. (V. WE), The following summarizes the imponant points of the meeting 1. The CDPIIE indicated that the discharge limits for ammonia contained in their letter of February 4, 1999 are not correct and do not have to be met. The final limits will be determined pending completion of the UAS, (Preliminary calculations indicate that the discharge limit for ammonia would be considerably higher: 5 to 20 mgtL of total ammonia, using the state's input values and assuming a Class 2 designation.) 2 The CDPHE indicated that the Spring Valley drainage should likely be a Class 2 aquatic life stream. Dennis indicated that the drainage is in the "all tributaries...." segment, the state did not have any site-specific data when it was classified for Class 1 aquatic life. and that the classification of other creeks has been changed based cn a site-specific analysis (e.g., Brush Creek). 3. The CDPHE indicated that designation as Class 2 aquatic life would lead to segmentation, and designation as a "use protected" sueam. Dennis indicated that it would make sense to have the entire drainage (including Landis Creek. Spring Valley, and the Red Canyon) as a new segment (e.g., Segment 3a). The use protected designation would mean that the stringent antidegradation review process would not apply. The Class 2 designation also wrrgnt Water Engineers, lr 74901N 26'" Avenue, Ste. 100A, Denver, CC 6071' Tel 303/460.1700, Far 301480.1020. e-mail.krwrgtirgwrightwaler :err, 11aIll (18t '.Of13,L f1i Ni LH') b,M 9c:1]I Si1H111Yt) APR. 22. 1999 3:07PM LEAVENWORTH & TESTER, P. C. NO, 9460 Metnoratadum to Greg Boeker, Chairman April, 22, 1999 Page 2 means that there is some flexibility as to the ammonia standard For example, a standard of 0.06 or 0.1 milligrams per liter (mg/L) of un -ionized anunonia may be found to be appropriate. 4. The discharge limits for ammonia provided in rhe leiter of February 4, 1999 from thc state are not correct. However, the state is not going to recalculate these numbers, pending completion of the UAS. 5 The CDPHE and USEPA agree with the scope of the proposed work plan for thc UAS. Sara!- Johnson suggested: 1) contacting the Division of Wildlife to gel any data r_hat they have ori fish or aquatic resources in the Spring Creek drainage, and 2) looking al other comparative creeks in the area. She also asked if Laurie Martin, biologist with the CDPHE. could attend the field work. 6 The appropriateness of the current Recreation Class 1 designation was also discussed. Beth the CDPHE and US)=PA agreed that this likely an inappropriate classification. The creek should be changed to Class 2 Recreation. 7. Miscellaneous items discussed are as follows: • There is no need to look at the Roaring Fork River due to the amount of dilution provided. • The use attainability study should include ar assessment of the aquatic life potential with the effluent in thc creek_ • The state does not have any specific guidelines as to what constitutes "minimum requirements" for Class 1 or Class 2 aquatic life uses. • The schedule for the August hearing is as follows: • Deadline to file for party status: early June. ■ Pre -hearing statements: =6/28, ■ Pre -hearing conference: ±7/14, Rebuttal statements; ±7/28, Hearing: 8/9. cc: Dean Gordon •%9Q I.0cli100uo'spnnpalley.dcc Wriuhl Warr engineers .
