08i06i99 15:05 CHATHAMI COUNTY MANAGERS OFFICE -~ 9196443004 NO.686 P003i004 10 regional facility have stated that they do not have any regulatory influence regarding how Cary clmoscs to shah its private facility with others. During the design period of the Chatham County water Treatment Flant, Chatham county staff evaluated several different raw water aherriatives to serve the plant including a partnership with Cary as well as an independent intake. Oversight and regulatory groups such as the state and the Army Corps of Engineers recommended very forcefully against the construction of a separate intake and urged the County to partner with Cary/Apex. At the time, the Cary/Apex intake had a small amount of excess capacity that was dcbami:red to be Sufficient to meet Chatham County's Slwr[-berm needs. Chatham County need Cuy 6igned a 10 year contract with the understanding that future intake expansion efforts would ita±lude Chatham County. The contract clearly staffed that CarylApex planned on sharing the use of its facility with others in the future. Since the time the original contract was signed, Cary has had high growth rates that have resulted in water dernattds exceeding their Jordan Lake allocation and their production capability. Cary has requested an increased allocation from the state and hss prepared rngineering plans for system upgrades to increase their water supply. The upgrades include an expansion of the intake. According to Cary staff, the expansion plan did not take into consideration Chatham County's needs. For.example, the engineer wanking ~ the project never modeled Chatham County's usage in preparing the pump design. As a result, according to Cary, the intake does not have sufficient capacity to serve as a permanent water source for Chatham Coumy's treatment plant. Cory's position towards a Chatham County partnership is not clear. In some cozrespondencxs, Cary has urged Chatham County to construct their own intake since Cory's growth projections show that there may not be any long-term surplus capacity in their facility. In other responses, Cary has suggested that Chatham County carry out their own engineering study and propose modifications to the planned intake design for Cary to consider. Neither of the positions are conducive to regional cooperation and they have resulted in inefficient planning and needlessly duplicated enginarittg studies. Chatham County is currently studying posstbk design modifications for Cary to consider. Under the existing framework, Cary/Apex maintains complete control of their intake facility and they are under no obligation to make their facility available to others. In addition, some of Cory's political leadership has stated a desire to control growth in Cary by limiting the expansion of the water system including the intake. This type of restriction, while possibly acceptable for a private facility, makes the operation of a regior~I facility almost impassibk. Chatham County has had numerous meetings with officials from the Division of Water Resources and the Army Corps of Engineers to discuss the intake. Officials at these mentings, particularly officials from DWR have bear reluctant to become involved in the situation. The general opinion has been that the intake is a private facility owned and operated by CarylApex, and the organizations are unable to control how the facility is shared or not shared with others utilities c.
