Tony - As per my voice -mail, is this format OK? Also, some specific questions: 1. Did I descirbe IBT issue correctly? (page 5 at bottom, under Wastewater Return Alternatives) 2. Do we need to do anything to address per capita use issue brought up last night, or is DWR going to defend those numbers? 3. Do you need any further discussion of the existing welts, or can you (or Water Supply folks) provide us with any formal recommendation that they not be used long-term? 4. If you have questions or ask Holly Springs for more informationwill it need to be submitted by July 23, or will you be doing your review after that date? Please call me when you get a chance. I will be in the office through Thursday, then will be gone for 4 weeks. Stephanie and I plan to finalize this document by the end of the week. However, Tommy Esqueda can address questions while I'm gone. Leila Goodwin o-24Fnx June 30,1997 Mr. John Morris, Director Division of Water Resources North Carolina Department of Environment, Health and Natural Resources PO Box 27687 Raleigh, NC 27611-7687 Dear Mr. Morris: Subject: Supplement to Jordan Lake Allocation Application The Town of Holly Springs submitted an application for a water supply allocation from B. Everett Jordan Lake to the Division of Water Resources (DWR) in January, 1997. DWR subsequently recommended that Holly Springs reoeive an allocation of 0.5 million gallons per day (mgd), which is less than the amount requested in the application. With this letter, I am requesting that the DWR consider additional information that supports an allocation of 2.0 mgd for the Town of Holly Springs. The attached Supplement to the January, 1997, Jordan Lake Water Supply Allocation Application, documents the need for this allocation to meet potable water demands through the year 2015. Please call our Town Engineer, Stephanie Sudano (919-5S7-3935), or our consultant, CH2M HILL (Leila Goodwin, 704-329-0072), if you have any questions. Sincerely, Gerald W- Holleman Mayor, Town of Holly Springs CLT/6-23LET c: Bill Lee, Assistant Town Adnunistrator Stephanie L. Sudano, PE., Town Engineer Leila Goodwin, P.E./CHM2HILL Supplement to the January, 1997 Jordan Lake Water Supply Allocation Application Town of Holly Springs June, 1997 Prepared by CH2MHILL SUPPLEMENT TO THE JANUARY, 1997 JORDAN LAKE WATER SUPPLY ALLOCATON APPLICATION FOR THE TOWN OF HOLLY SPRINGS Introduction This document supplements the Jordan Lake Water Supply Allocation Application for the Town of Holly Springs, submitted in January, 1997. Based on that document and on subsequent meetings between Holly Springs and Division of Water Resources (DWR) staff, the DWR recommended an allocation of 0.5 million gallons per day (mgd) for Holly Springs. The basis for the DWR recommendations was presented it Appendix F of Jordan Lake Water Supply Storage Allocation Recornmendations in March, 1997. This Supplement addresses the following issues to support a larger allocation for the Town of Holly Springs, 1. The Town's existing water supply wells are no longer considered a long-term reliable water source, due to recent taste and odor problems. 2. The water supply contract with Raleigh is not yet in place 3. Transmission facilities must be constructed in order to use water from either Raleigh or Harnett County. 4. Harnett County has recently applied for a Jordan Lake allocation. Rather than simply Purchase water from Harnett County, Holly Springs prefers holding an independent allocation. 5. The current allocation of 0,5 mgd does not allow for the possibility of continuing the existing contract with Apex for 0.75 mgd. These issues are addressed in the following sections, which are organized, according to the sections in the January, 1997, submittal. 1. Population and Water Use Projections DWR population and water use projections (Table 1-1), presented in Appendix F of Jordan Lake Water Supply Storage Allocation Reconiniendations in March, 1997, will be used. TABLE 1-1 Population and Water Use Projections Town of Holly SOrinas Year Population Average Daily Demand (MGD) 1995 3,500 0.25 2000 10,500 1.1 2005 18,000 1.9 2010 22,400 2.3 2015 27,100 2.8 2020 31,700 3.2 2025 35,800 3.6 CLT/JUNESUPP 2 SUPPLEMENT TO THE JANUARY, 1997 JORDAN LAKE WATER SUPPLY ALLOCATON APPLICATION FOR THE TOWN OF HOLLY SPRINGS The issues listed above have a significant impact on the Town of Holly Springs current water supply system yield. The following bullets address the sources included in the original submittal and how they are treated in this supplement: • Holly Springs Wells. A yield of 0.37 mgd was included in the January, 1997 submittal. Due to recent taste and odor problems with the wells, they are no longer considered a reliable source. Therefore, the 0.37 mgd is reduced to zero starting in the year 2000. • Town of Apex. The current contracted amount of 0.75 mgd is included in 1995, and will be replaced with the requested Jordan Lake allocation by 2000. This is not changed from the January, 1997 submittal. • City of Raleigh. While the Town of Holly Springs is working on a contract with Raleigh for 1.0 mgd, there is no contract in place now. Transmission facilities are expected to be in place by about 1999. • Harnett County. Although the Town currently has a contract for 1 mgd of capacity in Harnett County's water treatment plant, transmission facilities must be constructed before the water can be used. Constriction may be complete by about 2001. The water from Harnett County will be supplied from Holly Springs' Jordan Lake allocation, and so is reflected in the requested allocation amount, rather than in the system yield. The resulting system deficit, and requested Level I Jordan Lake allocation (to meet demands through 2015), are shown below in Table 1 2. TABLE 1.2 Population and Water Use Projections Town of Holly Springs Year Average Daily System Yield System Deficit Proposed Jordan Lake Allocation to Demand (MGD) (MGD) (MGD) meet Projected Demands (MGD) 1995 0.25 1.12 - 2000 1.1 1.01 0.1 0.1 2005 1.9 1.0 0.9 1.0 2010 2.3 1.0 1.3 1.5 2015 2.8 1.0 1.8 2.0 'The wells (0.37 mgd) and Apex (0.75 mgd) are included in 1995.

Alternative Sources Holly Springs' alternatives for water supply are: • Jordan Lake - Acquire a dedicated allocation from Jordan Lake, which would be treated partly at the Cary/Apex WTP (0.75 mgd), and partly by Harnett County. At a minimum, this needs to include the existing 0.75 mgd obtained from the Town of Apex. • Harnett Counhf - purchase finished water from Harnett County (beyond the portion of Holly Springs' Jordan Lake allocation that would be treated by Harnett County). • City of Raleigh - purchase finished water from the City of Raleigh. These alternatives are summarized in Table 3-1. A detailed evaluation of each of the alternatives was presented in the January,1997 document and is not repeated here. The only exception is the Jordan Lake alternative involving Harnett County treatment of Holly Springs' Jordan Lake allocation. That alternative is discussed in more detail in the subsections below. CLTIJUNESUPP 4 SUPPLEMENT TO THE JANUARY, 1997 JORDAN LAKE WATER SUPPLY ALLOCATON APPLICATION FOR THE TOWN OF HOLLY SPRINGS TABLE 3-1 Altemative Water Supply Sources Town of Holly Springs Altemative Name Estimated Cost Water Quality Environmental Institutional Yield ($/1000 (excellent, Impacts (minor, Implementation (simple, (mgd) gal.) good, poor) moderate, major) typical, difficult) Jordan Lake (through 0.75 ' $1.87 ` good minor simple Apex) Jordan Lake (through 1.25 ` $2.57 good minor typical Harnett County) Harnett County (Cape unknown $2.57 good minor typical Fear River) City of Raleigh 1.0 $1.50 good minor typical ' Requested allocation to cover amount currently contracted with Apex Requested allocation to cover 1.0 mgd currently contracted, plus additional amount to be contracted later. ` Unit costs will be higher due to the need for delivery through Cary and Apex. Back capital charges will also likely increase this unit cost, depending on negotiations with Cary and Apex. - Unit costs are based on the unit cost for purchasing treated water from Harnett County. 3.1 Economic Evaluation The cost for having Holly Springs' Jordan Lake allocation treated by Harnett County should be similar to the cost for simply purchasing treated water from Harnett County. 3.2 Environmental Evaluation The environmental impacts for Harnett County treatment of Holly Springs' Jordan Lake allocation would be the same as those for purchasing water from Harnett County. Identical treatment, transmission, and distribution facilities are needed. The only difference would be that, under dry conditions, the water would come from the water supply pool, thus reducing the average elevation of Jordan Lake an insignificant amount, rather than from the Cape Fear River flow. 3.3 Institutional Evaluation The institutional impacts for Harnett County treatment of Holly Springs' Jordan Lake allocation would be the same as those for purchasing water from Harnett County. An additional contracted amount of 0-25 mgd would be needed by about 2013, assuming Apex still treats 0.75 mgd of Holly Springs' allocation. The Town of Holly Springs may elect to shift the proportional amounts treated by Apex and Harnett County. 3.3 Wastewater Return Alternatives The wastewater return impacts for having Holly Springs' Jordan Lake allocation treated by Harnett County would be the same as those for purchasing water from Harnett County. Under the proposed allocations, Holly Springs would not need an interbasin transfer (IIBT) certificate, since the water will be discharged into Utley Creek, ultimately flowing into the CLT/JUNEJ'UPP SUPPLEMENT TO THE JANUARY, 1997 JORDAN LAKE WATER SUPPLY ALLOCATON APPLICATION FOR THE TOWN OF HOLLY SPRINGS Cape Fear River past the point of withdrawal by Harnett County. The proposed allocation of 0.75 mgd to be treated by Cary/Apex would be both average day and maximum day flow, and therefore less than the amount needing an IBT certificate. 4. Conservation and Demand Management There are no changes or modification to the information presented in January,1997. 5. Plans to Use Jordan Lake The Town of Holly Springs is applying for a 2.0-mgd allocation from Jordan Lake to meet water supply demands through 2015. A portion (0.75 mgd) of the water would continue to be withdrawn at the existing eastern intake structure and transmitted to the Cary/Apex WTI' via the existing transmission line. This would require no additional facilities. The remaining 1.25 mod allocation would be released from the lake for withdrawal by Harnett County from the Cape Fear River. This is similar to simply purchasing finished water from Harnett County, but gives Holly Springs a dedicated source of water. Since the development of water supply contracts with Harnett County and the Cite of Raleigh has proved to be more complicated than expected, the Town of Holly Springs, feels it's best alternative is to obtain a Jordan Lake allocation. While the above plans are the preferred means of using the Jordan Lake allocation, Holly Springs will have the option of building its own water treatment plant, shifting the amounts treated by Cary/Apex and Harnett County, or contracting with some entity other than Harnett County or Apex for treatment of the allocation. This allows maximum flexibility for the Town of Holly Springs. The following schedule is anticipated for Jordan Lake water use and related activities: Activity Expected Date Expansion of Cary/Apex WTP 2nd quarter 1999 Completion of Raleigh Connection 3rd quarter 1999 Completion of Harnett County Connection 2001 CLT/JUNESUPP Jordan Lake Water Supply Allocation Application Town Holly Springs January 1997 Prepared by CH2MHILL 136677.

Sudano, P.E., Town Engineer 10136 Jordan Lake Water Supply Allocation Application Town of Holly Springs January 1997 Prepared by CH2MHILL 136677. AL. FN. D 1 /03/wdc. FH5.d am b.9/96 Introduction The Town of Holly Springs is in Wake County, North Carolina, southwest of Raleigh and Cary, south of Apex, and north of Fuquay-Varina. The town is situated on a north-south ridge line that divides drainage basins for two major rivers: the Neuse River and the Cape Fear River. The town has been experiencing tremendous growth, especially in the early 1990s. Along with providing increased employment and economic growth, this rapid population increase is straining the existing infrastructure, requiring long-term planning and capital improvements on a continuous basis. An important element of water resource planning is the identification of a dedicated water source to meet forecasted demands. As a part of this process, the Town of Holly Springs is applying for a water supply allocation from Jordan Lake. Holly Springs submitted an allocation request to the Division of Water Resources on September 30,1996. This submittal is a revised version which addresses comments received from the DWR in a meeting on October 10,1996, and in a letter of October 14, 1996 (Attachment Q. This application provides information substantiating the need for this allocation in the following sections: Section 1-Population and Water Use Projections Section 2 - Current Water Supply Sources Section 3 - Alternative Sources Section 4 - Conservation and Demand Management Section 5 - Plans to Use Jordan Lake Attachment A - Local Water Supply Plan Attachment B -1995 Water Supply System Report Attachment C - October 14, 1996, Letter from DWR A map of the Holly Springs water supply service area, a letter from the Division of Water Quality to the Town of Cary concerning wastewater discharge in the Jordan Lake watershed, and a draft water quality monitoring plan were provided to the Division of Water Resources in the original application. 1. Population and Water Use Projections 1.1 Population The 1995 population of the Town of Holly Springs is estimated as approximately 3,500. Rapid growth has occurred in Holly Springs, especially from 1993 to 1995, when the population doubled. Holly Springs has approved development plans that will continue to support that rate of growth through at least 2000. Based on the approved plans, population is expected to reach 10,500 by 2000. While a buildout population has not been projected for Holly Springs, the population could reach 100,000 if development density was similar to that expected in the Town of Cary. A population of 48,000 in 2025 is projected based on increases of 1,500 residents per year after 2000. This rate is based on the growth in Cary within 30 years after a beginning population of 3,500, and is consistent with the approved development between now and 2000. This is a major increase in the population projections from those presented in the Town's approved Local Water Supply Plan, due solely to the fact that approved development for 2000 has already exceeded the previous projections for a much longer time period. Table 1-1 shows the population projections for Holly Springs. TABLE 1-1 Population Projections Town of Holly Springs Water Service Area Year Water System Population 1995 3,500 2000 10,500 2005 18,000 2010 25,500 2015 33,000 2020 40,500 2025 48,000 1.2 Water Use Average daily water use for Holly Springs in 1995 was approximately 250,000 gallons per day (gpd). The month with the maximum average daily water use was September with approximately 410,000 gpd. The month with the minimum average daily water use was March with approximately 100,000 gpd. In 1995, Holly Springs water use averaged just over 70 gallons per capita per day. However, new development occurring in Holly Springs appears to include homes that will have higher water use, especially for irrigation. Therefore, Holly Springs is using the Town of Cary per capita water use for projections through 2025, rather than base projections solely on 1995 data. The water use rate for projections is 106 gallons per capita per day. While Holly Springs has not yet adopted a formal conservation/demand management program, it is expected that there will be some reductions due to new low-water use fixtures and increased awareness. Therefore, a 5 percent reduction in per capita demand is assumed in 2025, increased linearly from zero in 2000. Table 1-2 summarizes three types of water use projections in million gallons per day (mgd): average day demand (ADD), maximum day demand (MDD), and maximum weekly demand (MWD). Ratios for MDD/ADD and MWD/ADD are based on Cary/Apex WTP 2 records for 1995. Table 1-3 compares water use projections to allocation requests. MDDs are used in this comparison. Holly Springs is requesting a Jordan Lake allocation to meet water demands through approximately 2022. Since Holly Springs is pursuing several water supply alternatives, it is assumed that 2025 demands will be met with a combination of sources, including Jordan Lake.

Current system yield includes the following sources in addition to the Town's wells: • Town of Apex - the current contracted amount of 0.75 mgd is included in 1995, and will be replaced with the requested allocation from Jordan Lake in later years. • City of Raleigh - 0.5 mgd, currently being contracted, through 2011. • Harnett County -1.0 mgd contracted, plus additional 1.0 mgd amendment under development.

Current Water Supply Sources Under normal conditions, Holly Springs gets its water supply from a combination of groundwater wells located near the center of town and from the Town of Apex. The town has three operating groundwater wells with a combined yield of 0.37 mgd. In September 1993, the Town of Holly Springs and the Town of Apex entered into an agreement for water. This water contract was amended in May 1996 to provide for delivery of up to 0.75 mgd of Apex's current raw water allocation from Jordan Lake to Holly Springs. The water is treated at the Cary/Apex Water Treatment Plant (WTP) and is delivered to Holly Springs through the Towns of Cary and Apex. Holly Springs has a contract for 1.0 mgd with Harnett County, with an additional 1.0 mgd amendment being developed. A contract with the City of Raleigh, for 0.5 mgd, is also under development. The Town of Fuquay-Varina can supply additional water during emergency conditions. Details of the current water supply sources are shown in Table 2-1.

' 1.0 mgd contracted, 1.0 mgd being added by amendment Contract under development Contract for emergency use, unspecified amount 4 3. Alternative Sources Currently, the Town of Holly Springs is evaluating several water supply alternatives to sustain its projected growth. Holly Spring's alternatives for water supply are: • Jordan Lake -acquire a dedicated allocation from Jordan Lake, which would be treated at the Cary/Apex WTP and delivered by the towns of Cary and Apex. This needs to include the existing 0.75 mgd obtained from the Town of Apex. • Harnett County -purchase finished water from Harnett County, above the currently planned 2.0 mgd. • Raleigh -purchase finished water from the City of Raleigh, above the 0.5 mgd currently being contracted. These alternatives are summarized in Table 3-1 and evaluated in this section. Holly Springs has also evaluated the option of building a WTP to treat water from the Cape Fear River. Because of cost considerations, this is not considered a feasible alternative, and is not addressed further. TABLE 3-1 Alternative Sources Town of Holly Springs Institutional Estimated Water Quality Environmental Implementation Alternative Yield Cost (excellent, Impacts (minor, (simple, typical, Name (mgd) ($/1000 gal.) good, poor) moderate, major) difficult) Jordan Lake 4.5 $1.87 good minor typical Harnett County unknown $2.57 good minor typical Raleigh unknown $1.50 good minor typical ' Requested allocation b Unit costs will be higher due to the need for delivery through Cary and Apex. Back capital charges will also likely increase this unit cost, depending on negotiations with Cary and Apex. 3.1 Economic Evaluation Costs for construction alternatives were developed using a 20-year capital recovery period, 5.5 percent interest and 4.5 percent inflation, as specified by DWR, unless otherwise specified. Jordan Lake. The total cost is a combination of the capital costs for the expansion of the Cary/Apex WTP, operation and maintenance costs based on 1995 figures, and the cost of purchasing Jordan Lake water. The capital costs for expansion are based on an engineer's 5 estimate of expanding the WTP from 16 mgd to 40 mgd. The unit cost is derived from the costs for a 24-mgd expansion of the WTP. Costs for Holly Springs will be higher due to the need for transmission through Cary and Apex's distribution systems. Back capital charges will also likely increase this unit cost, depending on negotiations with Cary and Apex. Harnett County. The cost of purchasing finished water from Harnett County is based on an engineer's estimate of capital and operation and maintenance costs. Raleigh. The cost of purchasing finished water from the City of Raleigh is based on estimates of capital charges for production facilities and debt service on delivery facilities. 3.2 Environmental Evaluation Environmental impacts of all three alternatives —Jordan Lake, Harnett County, and Raleigh — are minor, because new infrastructure requirements are low or would occur in currently developed areas. A water distribution system would be required in new development areas regardless of the water supply source; therefore, the environmental impacts associated with this system are not included in this analysis. The infrastructure requirements unique to each alternative are described below. Jordan Lake. Development of this alternative would require upsizing the transmission line from Jordan Lake to the Cary/Apex WTP and expanding the Cary/Apex WTP. Expansion of all of these facilities is already planned to handle expected growth in the towns of Cary and Apex and other surrounding communities. For Holly Springs to obtain additional water from this source would require only an incremental increase in already planned expansions. The expected environmental impacts would be minor. Harnett County. As part of the planned 2 mgd supply currently being contracted, a new pipeline will be constructed to connect the Harnett County system to the town's system. The pipeline will be designed for more than 2.0 mgd, so further expansion will not be needed for some time. Expansion of the WTP is already planned to handle expected growth in Harnett County, including Holly Springs. The expected environmental impacts for additional WTP expansion would be minor. Raleigh. A combination of passing water through existing county water lines and a new pipeline is planned for the 0.5 mgd contract being developed, to connect the City of Raleigh system to the town's system. The expected environmental impacts for additional expansions to these pipelines, for obtaining more than 0.5 mgd, would be minor. 3.3 Institutional Evaluation Jordan Lake. The Town of Holly Springs and the Town of Apex have an agreement in place that provides for delivery of 0.75 mgd of water from Jordan Lake to Holly Springs. This agreement would need to be expanded, possibly to include the Town of Cary. Expansion of the Cary/Apex WTP is already planned. Harnett County. The existing agreement between Harnett County and the Town of Holly Springs would need to be expanded. Raleigh. An agreement between the City of Raleigh and the Town of Holly Springs is in the process of being developed, and would need to be expanded. 3.4 Wastewater Return Alternative The Town of Holly Spring is located southeast of Jordan Lake, downstream of the dam. Therefore, the town's use of a Jordan Lake allocation would result in diverting flows out of the lake's watershed, although flows will be returned to the Cape Fear River basin. The feasibility and cost of returning part or all of this allocation to the lake's watershed is evaluated in this section. The Town of Holly Springs has an existing wastewater treatment plant (WWTP) with a permitted capacity of 0.50 mgd on Utley Creek, which flows to the Cape Fear River downstream of Jordan Lake. The plant replaced a 0.25-mgd plant that also discharged into the Cape Fear basin downstream of Jordan Lake. Holly Springs is currently designing a 1.0 mgd wastewater plant expansion on Utley Creek. Holly Springs also continues to explore options for further expanding the treatment capacity, including participating in the expansion of the South Cary wastewater treatment plant (SC WWTP) with the Town of Cary or constructing a new wastewater treatment plant on Middle Creek. The alternatives associated with the SC WWTP are discussed below. Discussions between Cary and DWQ indicate that it will be difficult to discharge wastewater to the Jordan Lake Watershed, for either the SC WWTP or the new West Cary WWTP (WC WWTP). 3.4.1 Cary and Apex's WWTP Alternatives Cary has proposed four alternative discharge locations to the Department of Water Quality (DWQ). DWQ addressed the feasibility of the alternatives in a letter to Cary, included in Attachment D. The first two locations, on Beaver Creek and on an unnamed tributary to Tom Jack Creek, were determined by DWQ to have zero flow during 7Q10 and 30Q21ow- flow conditions. As a result, DWQ indicated that they will not allow WWTP discharges at these two locations. The other two alternative sites are located below the Jordan Dam, resulting in a diversion of water from the Jordan Lake watershed. To consider these two alternatives, DWQ indicated that it would require the Town of Cary to develop a QUAL2E model for a part of the Haw River downstream of the B. Everett Jordan Dam. A DWQ permit for expanding the WC WWTP beyond a 6-mgd capacity would depend on the results of the model. Cary also has investigated the potential for diverting a part of the SC WWTP discharge to the Jordan Lake watershed. The estimated cost of constructing a new 26-mile, 30-inch force main and an associated pumping station to divert the SC WWTP discharge to the Jordan Lake watershed is $19.5 million. This discharge would be subject to the same DWQ permitting restrictions discussed above. Preliminary response from DWQ indicates that discharge to tributaries of the Jordan Lake watershed is not feasible now. However, Cary and Apex have indicated they are willing to work with DWQ and the Division of Water Resources to develop feasible alternatives for returning water to the Cape Fear River basin, tributaries to Jordan Lake, or to the lake itself. 3.4.2 Interbasin Transfer Issues While Holly Springs' use of water from Jordan Lake is currently an interbasin transfer, the _ transfer is included in the Town of Cary's Jordan Lake allocation and interbasin transfer certificate. Cary has indicated that it will ask DWR to separate the interbasin transfers, so that Holly Springs would be responsible for transfers associated with the requested Jordan Lake allocation. The potential interbasin transfers from the Haw River Sub -Basin to the Cape Fear River Sub -Basin which would occur if Holly Springs wastewater continues discharging into the Cape Fear River Sub -Basin are shown in Table 3-2.

Approximately 40 percent of Holly Springs is located in the Neuse River Sub -Basin, with the remainder in the Cape Fear River Sub -Basin. For the purposes of this application, consumptive uses are estimated at 22 percent of water use'; therefore, 40 percent of consumptive uses are discharged into the Neuse River Sub -Basin. The interbasin transfers shown in Table 3-3 are estimated to have occurred during January through June of 1993, and total about 0.04 mgd on an average daily basis. Holly Springs began using water from Apex (Jordan Lake, Haw River Sub -Basin) in June, 1993, so there was no significant use from the Haw River Sub -Basin until July, 1993. Potential for interbasin transfer on July 1, 1993, was at least 0.3 mgd, which was the contracted supply available from Apex. ' Viessman, Warren, Jr. and Mark J. Hammer.

Conservation and Demand Management The Town of Holly Springs is in the process of adopting long-range voluntary conservation goals. A draft plan was included in the original September, 1996, submittal as Attachment F. The town intends to conduct the following actions: • Explore opportunities associated with new development for water reuse • Incorporate reuse facilities into a proposed 1-mgd expansion of the town's WWTP • Distribute educational materials to water customers and to the local elementary school • Prepare along -range water supply and water distribution system modeling study • Enact ordinances that require low -volume water usage plumbing fixtures for new construction As discussed in Section 2, this program is expected to reduce per capita demands 5 percent by 2025. Water use projections incorporate these reductions. Holly Springs water rates are listed in Table 4-1.

Plans to Use Jordan Lake The Town of Holly Springs is applying for a 4.5-mgd Level II allocation from the Jordan Lake water supply to meet current and future water use projections. The water would be withdrawn at the existing eastern intake structure and transmitted to the Cary/Apex WTP via the existing transmission line. Plans for expanding the WTP capacity are currently under way by the Town of Cary. Attachment E of the original September,1996, submittal included the proposed Jordan Lake water quality monitoring plan. The following schedule is anticipated for Jordan Lake water use and related activities: Activity Expected Date Completion of Raleigh Connection 1st quarter 1997 Completion of Harnett County Connection 1st quarter 1998 Expansion of Cary/Apex WTP 2nd quarter 1999 Construct new West Cary WWTP 1999 WDCR1045/011.DOC 10 Attachment A Local Water Supply Plan WDCR2044/001.DOC/1 SUPPLEMENT TO WATER SUPPLY PLAN TOWN OF HOLLY SPRINGS NORTH CAROLINA December 1996 Town of Holly Springs Engineering and Utility Departments PO Box 258 Holly Springs, NC 27540 (919) 557-3935 Town Engineer: Stephanie L. Sudano, P.E. This document is intended to supplement the Water Supply Plan dated October 2, 1995. The outline below mirrors that of the original water supply plan. Information from the original Water Supply Plan is not repeated here. CURRENT CONDITIONS During 1995, the Town of Holly Springs' population was approximately 3,500. Wells 1 and 2 are not used any more, because of low yield. The map submitted with the approved Local Water Supply Plan shows the locations of Wells 4, 5, and 6, which are currently in use. WATER USE Average daily water use for Holly Springs in 1995 was approximately 250,000 gallons per day (gpd). The month with the maximum average daily water use was September with approximately 410,000 gpd. The month with the minimum average daily water use was March with approximately 100,000 gpd. In 1995, Holly Springs water use averaged just over 70 gallons per capita per day. Table 1 shows the average monthly water use in million gallons per day (mgd) for each month. TABLE 1 1995 Water Use Town of Holly Springs Water Service Area Month Water Use (mgd) January 0.16 February 0.11 March 0.19 April 0.27 May 0.31 June 0.34 July 0.23 August 0.39 September 0.41 October 0.28 November 0.18 December 0.13 Annual Average 0.25 The breakdown of water by type of user is shown in Table 2. The production and billing records do not indicate any water loss for 1995. While this is probably due to metering differences and timing of measurements, it does indicate that any losses were probably minor. TABLE 2 Water Use by Type of User for 1995 Town of Holly Springs Water Service Area Type of Use Percent of Use Residential 90.6 Commercial 4.3 Industrial 2.7 Institutional 2.3 Unaccounted 0.0 The Town's five major water users were: Customer: MGD: Warp Technologies 0.00357 Triangle Tank & Truck Wash 0.00253 Devils Ridge 0.00229 Rose Haven Rest Home 0.00102 Ruth's Hair Place/Laundry 0.00010 WATER SUPPLY SOURCES The combined 12-hour yield of the Town's three wells is estimated as 183,800 gallons, based on the yield for Wells 4 and 5 and design capacity for Well 6 reported in the previous Local Water Supply Plan. Holly Springs obtained all water in 1995 from it's wells and from the Town of Apex. There are connection with the Towns of Fuquay-Varina and Cary, the City of Raleigh, and Harnett County HOLLY SPRINGS WATER USE FEES Holly Springs water rates are listed in Table 3. TABLE 3 Water Rates Town of Holly Springs Total Gallons Used In Town Out of Town 2000 and under $9.50 minimum monthly charge $14.25 minimum monthly charge 2001-5000 $2.75 per 1000 gallons $4.25 per 1000 gallons 5001 and over $3.75 per 1000 gallons $5.25 per 1000 gallons 3 WASTEWATER DISCHARGE INFORMATION The Town of Holly Springs has an existing wastewater treatment plant (WWTP) with a permitted capacity of 0.50 mgd on Utley Creek, which flows to the Cape Fear River downstream of Jordan Lake. The plant replaced a 0.25-mgd plant that also discharged into the Cape Fear basin downstream of Jordan Lake. FUTURE CONDITIONS The 1995 population of the Town of Holly Springs is estimated as approximately 3,500. Rapid growth has occurred in Holly Springs, especially from 1993 to 1995, when the population doubled. Holly Springs has approved development plans that will continue to support that rate of growth through at least 2000. Based on the approved plans, population is expected to reach 10,500 by 2000. While a buildout population has not been projected for Holly Springs, the population could reach 100,000 if development density was similar to that expected in the Town of Cary. A population of 48,000 in 2025 is projected based on increases of 1,500 residents per year after 2000. This rate is based on the growth in Cary within 30 years after a beginning population of 3,500, and is consistent with the approved development between now and 2000. This is a major increase in the population projections from those presented in the Town's approved Local Water Supply Plan, due solely to the fact that approved development for 2000 has already exceeded the previous projections for a much longer time period. Table 4 shows the population projections for Holly Springs. TABLE 4 Population Projections Town of Holly Springs Water Service Area Year Water System Population 1993 1,784 1995 3,500 2000 10,500 2005 18,000 2010 25,500 2015 33,000 2020 40,500 2025 48,000 Per capita water use in 1995 was about 70 gallons per capita per day (gpcd). However, new development occurring in Holly Springs appears to include homes that will have higher water use, especially for irrigation. Therefore, Holly Springs is using the Town of 4 Cary per capita water use for projections through 2025, rather than base projections solely on 1995 data. The water use rate for projections is 106 gallons per capita per day. While Holly Springs has not yet adopted a formal conservation/demand management program, it is expected that there will be some reductions due to new low-water use fixtures and increased awareness. Therefore, a 5 percent reduction in per capita demand is assumed in 2025, increased linearly from zero in 2000. Table 5 summarizes per capita water use, and average (ADD) and maximum (MDD) water use projections in mgd. Ratios for MDD/ADD are based on Cary/Apex WTP records for 1995.

The contract with Harnett County is being expanded to 2.0 mgd. FUTURE WASTEWATER DISCHARGE INFORMATION Holly Springs is currently designing a 1.0 mgd wastewater plant expansion on Utley Creek. Holly Springs also continues to explore options for further expanding the treatment capacity, including participating in the expansion of the South Cary wastewater treatment plant (SC WWTP) with the Town of Cary or constructing a new wastewater treatment plant on Middle Creek. 5 Attachment B 1995 Water Supply System Report WDCR2044/001.DOC/2 North Carolina Department of Environment, Health and Natural Resources Division of Water Resources WATER SUPPLY SYSTEM REPORT Report for January 1 to December 31, 1995 Completed By: Stephanie L.

CH2M Hill 4824 Parkway Plaza Blvd Building 1, Suite 200 Charlotte, NC 282174968 SUBJECT: Jordan Lake Allocation Application Review Dear Leila: We appreciate you meeting with us so promptly to discuss the Jordan allocation applications that you prepared. Based on our discussions, I have put together this summary of our comments. General Comments on All Applications ConsistencX. Water use and system information in the application should be consistent with information in the accompanying local water supply plan and water supply system report. Population. The projections were drastically different from the information contained in the applicants' approved local water supply plans. Provide the necessary documentation to justify the increased population projections. Consider whether or not the buildout scenario is reasonable to assume for all of the applicants during this planning period. Water Use. Provide historical and projected per capita water use for each applicant, including how it was developed and, if applicable, why projected per capita use will change. Conservation. All applicants are strongly urged to quantify the potential for demand reduction. As a minimum, applicants should take into account the effect of low -flow fixtures, since state building code and federal manufacturing requirements already ensure that all new construction will have low -flow fixtures. P.O. Box 27687, Raleigh, North Carolina 27611-7687 Telephone 919-733-4064 An Equal Opportunity Affirmative Action Employer 50% recycled/ 10% post -consumer paper Page 2 SUBJECT: Jordan Lake Allocation Application Review October 14, 1996 Interbasin transfer. Exactly how the allocation and the interbasin transfer certification processes will be coordinated is not fully decided; however, it is certain that the processes will be interrelated. In fact, the allocation rules explicitly state that for allocations involving transfers, "the Commission will coordinate the review of the diversion with the review of the allocation request." As discussed, out -of --basin water consumption is considered an interbasin transfer under the existing statutes and rules. Therefore, it is important that some estimation of future water consumption be provided to determine if EMC certification is necessary. This should be presented in the form of a basic water balance that includes withdrawal, consumption, and discharges into and out of the basins involved for each of the projection years. "Grandfather" provisions in the statutes allow for increases in existing transfers by 25% or up to the system's transfer capacity, as defined in the rules. To determine if these provisions apply, applicants with existing transfers should include their average annual transfer amount from July 1, 1992 through June 30, 1993 and their system's transfer capacity as of July 1, 1993 (existing or under construction). [These grandfather provisi uons would not apply to Cary/Apex because they have a prior transfer certificate.] The interbasin transfer rules state that responsibility for obtaining a transfer certificate lies with whomever owns the pipe when it crosses the basin boundary. However, as pointed out, another party may assume this responsibility, subject to approval by the Division of Water Resources. If applicable, the applicant should indicate who owns the pipe and who intends to be responsible. Plans to Use Jordan Lake. The combined requested allocation amount for Cary/Apex, Wake County/RTP, Morrisville, and Holly Springs exceeds the available capacity of the Cary/Apex WTP. Provide a discussion of how water withdrawal and treatment needs in excess of the available intake and WTP capacity will be met. Additional Specific Comments Cary/Apex. Relevant portions of the Cary Growth Management Plan should be provided with the revised application. As stated above, even though Cary/Apex plans to return its treated wastewater to the Cape Fear basin, consumptive water losses that occur in the Neuse basin would be considered a transfer. Based on their 29-mgd additional allocation request and a 23-mgd wastewater return, this would indicate a 6-mgd consumptive loss. Page 3 SUBJECT: Jordan Lake Allocation Application Review October 14, 1996 Wake County/RTP. Cana more suitable peak water. use factor be determined for the industnal/commercial development expected? It appears that most of the Wake County portion of RTP is within the Haw River sub -basin, not the Neuse River basin. It is unlikely that the consumptive losses within the Neuse portion of RTP South would exceed the 2.0-mgd threshold for certification, however, Wake County should document this situation in its application. Morrisville. Because of Morrisville's predominantly business development, would a different peak water use factor be more suitable for its water use projections also? Also, how does the "238 percent" business water use factor compare to the "water use per acre" methodology used for Wake County's projections? Morrisville's 2.0-mgd wastewater discharge capacity at the North Cary Pi WTP would be an interbasin transfer. If the additional 2.5-mgd of its requested allocation will be treated by Cary and returned to the Cape Fear Basin, the consumptive losses associated with use of that 2.5-mgd would also be considered a transfer. Morrisville only describes its plans for treating 3.0 mgd of its requested 4.5-mgd allocation. What are Morrisville's plans for using the remaining 1.5 mgd? Holly Spring. Holly Spring's 1.5-mgd WWTP discharge capacity into Utley Creek would be a transfer from the Haw River sub -basin to the Cape Fear River sub -basin. [This transfer would be less than the 2.0 mgd threshold for regulation.] Its planned future WWTP discharge into Middle Creek for the remaining 3.0 mgd of its request would also be an interbasin transfer (from the Haw River sub -basin to the Neuse River sub -basin) and would require certification. If you have any questions about these comments or do not feel that they fairly represent our discussions, please let me know. We look forward to receiving the revised applications.
