HomeMy WebLinkAboutReport on Chatham County's Request to Access its Jordan Lake Water Allocation through OWASA's Jordan Lake Property and Approved Intake Location March 16, 1999 Mr. Daniel C. VanderMeer, Chair Board of Directors Orange Water and Sewer Authority PO Box 366 Carrboro,NC 27510-0366 Dear Mr. VanderMeer: The Orange County Board of Commissioners offers the following comments regarding the local water supply and water quality protection issues discussed at the October 1, 1998 meeting involving Orange and Chatham Counties,the Towns of Carrboro, Chapel Hill and Hillsborough, and OWASA. Clearly our region's explosive growth makes it imperative that all local jurisdictions work together to protect the quality of all of our natural resources and promote the most environmentally sound usage of those resources. Orange County is located in the upper portions of a number of important and environmentally sensitive water supply river systems. Consequently we are acutely conscious of the need to be judicious in our efforts to be good stewards of our available water resources, and of the need to work with the local governmental jurisdictions within and adjacent to Orange County to develop the strategies and accomplish the goals consistent with that stewardship. In accordance with this philosophy,the Orange County Board of Commissioners commends OWASA on its efforts to bring stakeholders in local water supply issues together to discuss issues of mutual concern. Relative to the issues raised at the October V meeting,the Board of County Commissioners is of course interested in facilitating a solution for Chatham County's water needs. Since there have been additional discussions on this issue since October V, it would be very helpful for Orange County to receive clarification concerning the options open to Chatham County at the present time, including Chatham County's preferred solution. If an intake on the western side of Jordan Lake is the preferred option,then Orange County would be interested in having discussion with OWASA; state and federal authorities controlling access to and allocation of Jordan Lake water supplies; other local jurisdictions having interest in Jordan Lake's available water supplies; and Chatham County, in consultation Mr. Daniel C. VanderMeer March 16, 1999 w w page 2 with the Authority's constituent governments,to explore the use of OWASA's property as a potential intake side to provide access to Jordan Lake water supplies for Chatham County while still ensuring that OWASA's potential access to its Jordan Lake allocation is preserved. The Orange County Board of Commissioners is ready to join all existing and potential users of Jordan Lake water supplies in studying, developing and implementing effective watershed and water quality protection strategies. The Orange County Board of Commissioners is similarly ready to work with Chatham County to discuss, develop and implement enhanced watershed and water quality protection strategies for University Lake water supplies. If I may provide any additional input or staff assistance,please contact me at your earliest convenience. I would appreciate your advising the Board of County Commissioners when OWASA has ascertained the range of options for meeting Chatham County's water needs, including their preferred option. Sincerely, Alice M. Gordon, Chair Orange County Board of Commissioners cc Chatham County Board of Commissioners TOWN OF CARRBORO E0 V[E NORTH CAROLINA • DEC 3 1998 C November 30, 1998 Mr. Dan VanderMeer, Chair OWASA Board of Directors P.O. Box 366 Carrboro,N.C. 27510 Dear Mr. VanderMeer: At the October 1"joint meeting between the local governments and the OWASA Board, it was determined that each local government would discuss a number of issues raised by Margaret Pollard, Chair of the Chatham County Board of Commissioners. It was further determined that each jurisdiction would provide guidance to OWASA. Pursuant to that discussion, the Carrboro Board of Aldermen and I have discussed Chatham County's request for cooperation on water-related issues. First, it should be noted that the Carrboro Board of Aldermen is interested in being a good neighbor to our friends in Chatham County. We believe our future is closely connected to theirs and that it is in the best interest of all parties to cooperate whenever and wherever reasonably possible. Second, with regard to the specific issued raised at the October 1"meeting,we provide the following input for your consideration: a) Carrboro does not support the notion of OWASA extracting water from Jordan Lake for consumption by OWASA customers. b) Carrboro could support sharing water with Chatham during emergencies. c) Carrboro supports developing a policy, which would allow Chatham County, access to Jordan Lake water via OWASA'S intake rights. We acknowledge that there are any number of considerations that must be explored to ensure that the interests of all parties are secure. 301 WEST MAIN STREET. CARRBORO.

We believe that further collaboration between OWASA and Chatham County offers resource management, environmental, and economic benefits that will not be realized if future Jordan Lake water supply decisions are based only on the needs of individual users. However, we request that you offer clear and concise policy guidance to OWASA so that we may determine as soon as possible whether to proceed with, or defer, any further consideration of joint efforts with Chatham County in this matter.

This paper provides follow up information to the"Jordan Lake as a Regional Water Source"meeting among officials of Carrboro, Chapel Hill, Chatham County, Hillsborough,Orange County,and Orange Water and Sewer Authority held on October 1, 1998. The OWASA Board of Directors discussed this information at their December 10, 1998 meeting with the intent that this discussion paper would support discussions of individual elected boards as they work with Chatham County on matters of mutual interest, including collaborations or possible cooperation between OWASA and Chatham County on development of water resources. What happened at the October 1, 1998 joint meeting? A representative of the North Carolina Department of Environment and Natural Resources provided an informational presentation about Jordan Lake, the allocation process,its value as a regional resource, and the expectation that only one water intake site will be developed on the western side of Jordan Lake. Representatives from each of the local entities briefly described their respective long and short term interests in Jordan Lake. The central question of the meeting was posed by Chatham County: "Is there interest in OWASA working with Chatham County to develop an intake, even if Chatham needs it earlier than OWASA would otherwise?" The meeting participants agreed to discuss this question and related issues within their individual boards and reconvene as a large group during the first week in March 1999. A date and location have not yet been specified(Attachment 1). What are OWASA's long and short term interests in Jordan Lake? Jordan Lake represents an important future raw water supply option for OWASA. Existing sources at University Lake,Cane Creek, and the Stone Quarry Reservoir, as well as the potential benefit of an expanded Stone Quarry Reservoir, can not sustain the community's needs indefinitely. OWASA is committed to maintaining a viable and reliable range of future options. More detailed information on the extent and timing of future water needs is currently being developed through OWASA's Comprehensive Water and Sewer Master Plan project. Preliminary water supply and demand data will be available by the spring of 1999. 400 Jones Ferry Road F-4-1 Opportunity Employer Voice(919)968-4421 PO Box 366 Printed on Recycled Paper FAX(919)968-4464 Carrboro,NC 27510-0366 wwlf:014asa,org Discussion Paper--Jordan Lake Options for OWASA December 18, 1998 Page 2 What stake does OWASA already have in Jordan Lake? Since 1988, OWASA has held a Level II (long term) allocation of 10 percent of Jordan Lake's water supply storage capacity. This is expected to support an average withdrawal of 10 million gallons per day (mgd). OWASA makes an annual payment of approximately$19,000 to the N.C. Department of Environment and Natural Resources for this allocation. Additionally,OWASA owns 125 acres of land adjacent to U.S. Army Corps of Engineers property on the western side of Jordan Lake, south of Highway 64(Attachment 2). OWASA purchased 88 acres in 1989 and 37 acres in 1995 for a total cost of $550,000. The Corps' amended Jordan Lake Master Plan designates an offshore intake site adjacent to this area, per recommendations of an engineering study conducted for OWASA in 1991 at a cost of $35,000. It is important to note that no regulatory action has been taken to grant OWASA or any other entity the right to use this site for water withdrawal purposes. OWASA currently has a$60,000 contract with NCDOT to install a casement under U.S. 64 in the vicinity of Mt. Gilead Church Road as part of the U.S. 64 improvement project. This will allow the installation of a future water transmission line without the major expense of boring or tunneling under the highway. Similar arrangements are planned as NCDOT improves Highway 15-501. What do we know about Jordan Lake's water quality? Data available from the past 10 years indicate that water quality in Jordan Lake is good and nearly indistinguishable in quality from other Triangle area water supply reservoirs, except in the northernmost section upstream of S.R.1008,where it is highly enriched with nutrients. Comprehensive watershed/water quality studies exist for other important reservoirs in the Triangle region, but no such study has been conducted for Jordan Lake. Consequently,there is no credible technical basis for estimating the water quality impacts of development projects or other activities proposed near Jordan Lake or in the watershed: Since 1988, OWASA has participated in the Triangle Area Water Supply Monitoring Program,which has several sampling sites in Jordan Lake and expects to contribute funds and staff support to the Jordan Lake watershed study proposed by the Triangle J Council of Governments. Additionally, OWASA plans to participate in special efforts to develop and calibrate a nutrient response model in order to determine whether nitrogen removal is warranted at wastewater treatment plants upstream of Jordan Lake. What facilities would OWASA need to withdraw water from Jordan Lake? Three basic systems would be needed to withdraw water from Jordan Lake and treat it at the OWASA's Jones Ferry Road Water Treatment Plant(WTP) in Carrboro: (1) intake system, (2)two pumping stations, and(3) a transmission pipeline. Intake facilities would be located to provide water in sufficient quantities, even during low lake levels. The intake must draw from multiple levels in the lake in order to obtain the highest quality water at any given time. Discussion Paper--Jordan Lake Options for OWASA December 18, 1998 Page 3 The intake structure could be located either onshore or offshore. An onshore structure would be served by multiple underground pipes extending into the lake at different depths below the water surface (Attachment 3). An offshore structure located in the lake would employ multiple intake gates at different depths providing water back to shore through a single pipeline(Attachment 4). The preferred intake configuration would be determined through additional engineering analysis. A pumping station is needed to transport water from the intake system through approximately 15 miles of transmission pipeline to OWASA's WTP. An additional booster pump station would be needed to overcome friction losses and elevation changes between Jordan Lake and Carrboro. A potential pipeline route is shown in Attachment 5. How much will these facilities cost? The cost figures provided are very preliminary and represent rough estimates only. Facilities Cost Assumptions Water Intake System $2.0 million 50 mgd intake structure with 1,000 feet of piping Pumping Stations $5.9 million 50 mgd pumping station structure with 10 mgd of installed capacity and a 10 mgd booster pumping station Transmission Pipeline $18.6 million 80,000 feet of 36 inch pipeline Total $26.5 million What options are available to OWASA and Chatham County for collaborating on the withdrawal and transmission of water from Jordan Lake? What are their advantages and disadvantages? There appear to be five basic options available for collaboration, but substantially more engineering work. will be needed to identify and develop the list of possible options: 1. Do not collaborate on any facility development at this time, but allow OWASA's property to be used by Chatham County or others. 2. Collaborate on a joint intake system only. 3. Collaborate on an intake system and make a portion of OWASA's Jordan Lake property available for Chatham County to use in pumping raw water to its own treatment plant. 4. Collaborate on an intake system and pumping station at the lake. 5. Collaborate on an intake system, pumping station at the lake, and portions of the transmission pipeline. Discussion Paper--Jordan Lake Options for OWASA December 18, 1998 Page 4 The U.S. Army Corps of Engineers and the N.C. Department of Environment and Natural Resources have expressed the strong desire to have only one intake system located on the west side of Jordan Lake. Limiting construction to one facility would minimize environmental and community disruptions and provide substantial economies of scale. The only known disadvantage to OWASA in proceeding with a joint intake system would be the expenditure of capital funds in advance of OWASA's actual need for the facility. Depending on the scale, cost,and financing method for project, it is possible that present value costs to OWASA should be lower under this near term collaborative scenario than if OWASA deferred its investment to the future. Cooperation on a joint pumping and transmission system would provide many of the same benefits noted above, but because these facilities must be carefully tailored to the specific needs of each user,they are less accurately estimated in advance than the more generic requirements for an intake system. OWASA would incur significant additional expenses before such facilities were needed if it participated with Chatham County in a joint project to provide pumping and transmission facilities in addition to an intake system. If OWASA and Chatham County cooperate on a joint intake system, OWASA believes that it could make a portion of its Jordan Lake property available for Chatham County to use in pumping raw water to its treatment plant. What other utilities might share a cooperative interest in a regional intake system? Orange County, Durham, and possibly Greensboro might have a future interest in Jordan Lake water. Cary and Apex might be interested in supporting an intake structure on the western side of Jordan Lake with sufficient capacity to supply their own needs during an emergency or shutdown of their existing intake on the eastern side of the lake. These possibilities and others will be evaluated through OWASA's Comprehensive Water and Sewer Master Plan Project now underway. Are there any other collaborative opportunities to consider? There can be substantial local and regional benefits if OWASA, Chatham County,and others participate in a Jordan Lake watershed study. Other regional benefits beyond OWASA's purview might be facilitated through OWASA's participation with Chatham County on an intake system. As mentioned on previous occasions, it would be highly desirable to OWASA and its customers if the zoning and development requirements in Chatham County's portion of the University Lake watershed were consistent with rules in place in Orange County's and Carrboro's jurisdictions. At some time in the future OWASA will require Chatham County's approval to construct the infrastructure needed to transmit water from Jordan Lake to OWASA's facilities in Orange County. Discussion Paper--Jordan Lake Options for OWASA December 18, 1998 Page 5 OWASA and Chatham County have agreed to establish an emergency only finished water interconnection along U.S. 15-501 at the Orange County line. Chatham has already invested$120,000 to extend its 16- inch pipeline to the OWASA system. This emergency only interconnection will provide long-term benefit to both parties. What is OWASA's recommendation? OWASA believes there would be substantial environmental,technical, and economic benefits from collaborating with Chatham County to develop a regional raw water intake system at Jordan Lake, even though OWASA is not expected to need Jordan Lake water for at least ten years (this estimate is currently being refined through OWASA's Comprehensive Water and Sewer Master Plan project). OWASA does not propose participating in the joint development of pumping and transmission facilities from Jordan Lake to OWASA at this time due to the high costs and relative absence of short term need. There may be an opportunity to make a portion of OWASA's Jordan Lake property available for Chatham County to use in pumping raw water to its own treatment plant. Additional engineering analysis is needed to more fully evaluate these opportunities. The OWASA Board of Directors believes that it is highly desirable that the March 1999 follow-up meeting with local governments and the OWASA Board be scheduled as suggested during the October 1, 1998 Joint Meeting. Given the range of collaborative arrangements that presently exist or are possible for the future, it would be beneficial for all parties to establish and reinforce a strong constructive partnership with Chatham County at the earliest opportunity. Whatever the outcome of future meetings of Chatham County officials with their counterparts from Orange County, OWASA staff should maintain close communications with Chatham County engineering personnel to monitor the development of the Chatham water supply and distribution system and to, identify opportunities for technical cooperation. 0aA4AJN&tIA f ek-- Dan C.

Question Posed By Chatham County ♦ Is there interest in OWASA working with Chatham County to develop an intake,even if Chatham needs it earlier than OWASA would otherwise? Questions Raised By Participants ♦ What is the level of participation needed by the various governmental entities(e.g.,amount of capital required,short-term vs. long-term costs of developing intake at this time)? ♦ What is driving Chatham County's need(e.g.,amount of development)? ♦ Under what conditions might Chatham share/use OWASA's intake location? What are the options? ♦ Does Chatham have an interest in working with Orange County governments to maintain a rural buffer in southern Orangelnorthern Chatham area? ♦ Is Jordan Lake indeed considered a regional water supply? Is Chatham included in the region? ♦ Who should be involved in this discussion(i.e.,governing boards'role vs.OWASA's role)? ♦ Can we develop a clear sense of each jurisdictions directinterests in Chatham's use ofJordan lake? ♦ In the long term,will Orange County entities need to take water from Jordan Lake? ♦ What will OWASRs master plan indicate about its timing for the need of Jordan Lake`s water? t What forum should this issue come back to? Are participating entities willing to have a conversation with their entire boards and then come back together to discuss? ♦ If Chatham County can act on its own,what is its incentive to cooperate on land use,etc.? The Participating Orange County Entities Agreed To Have A Conversation With Their Entire Boards And Then Come Back Together To Discuss Chatham-County's Use Of The OWASA Intake Site On Jordan Lake. They Identified Several Pieces Of Information That They Needed Before They Would Have This Board Discussion: 1. Information from OWASA on projected water use,options f5r(and cost of)developing intake site 2. Information from Chatham County regarding water needs 3. Exchange of land use plans and utility line plans between Orange and Chatham counties 4. Engineering,information on the possibility of building an intake sie that could be expanded.later 5.
