The application fee for the 401 was never submitted, and it gets much more complex from there. Attached is the letter DWQ sent in 2005 in response to the Corps' Public Notice, in which we requested payment of the application fee, among other information needed to review the application. Subsequently, the Corps put this project into the Project delivery Team process, through which a variety of stakeholders are involved in moving a project from concept to permit application. At any given time, the Corps may only have one or two PDT's active, and they are typically very large, complex, or controversial projects. I'd be happy to discuss this process in more detail. I've also attached the most recent item in our file, dating from 2009. It include materials from the most recent PDT meeting in which we were involved. As you will see upon review of this document, the project remains in the early planning phases, as in Purpose and Need, to be followed by Alternatives Analysis, and so on. This will follow the NEPA process, which serves to meet SEPA requirements. It's possible the Corps has been involved with other discussions with the applicant in which we were not involved.

Director Division of Water Quality August 23, 2005 DWQ Project # 20051457 Cleveland County CERTIFIED MAIL: RETURN RECEIPT REQUESTED Cleveland County Sanitary District Attn: Butch Smith, General Manager Post Office Box 778 Lawndale, NC 28090 Subject Property: Proposed First Broad River Reservoir REQUEST FOR MORE INFORMATION Dear Mr. Smith: On June 30, 2005, the Division of Water Quality (DWQ) received your application dated April 5, 2005 to impact wetlands /waters to construct the proposed reservoir construction. The DWQ has determined that your application was incomplete and /or provided inaccurate information as discussed below. The DWQ will require additional information in order to process your application to impact protected wetlands and /or streams on the subject property. Therefore, unless we receive the additional information requested below, we will have to move toward denial of your application as required by 15A NCAC 2H .0506 and will place this project on hold as incomplete until we receive this additional information. Please provide the following information so that we may continue to review your project. Additional Information Requested: 1. Water Quality Certification Application Fee. An application fee of $475 is required for this project. This check should be made out to the NC Division of Water Quality and sent to the Central Office address listed below. 2. Environmental Documentation: Please provide a copy of the environmental documentation for this project. It is unclear whether an Environmental Assessment or Environmental Impact Statement has been done for this project under the State Environmental Policy Act (SEPA). Please contact Ms. Melba McGee at 919 - 715 -4194 to determine if preparation of this document is needed. In any case, this documentation must thoroughly examine all practical alternatives (including pumped storage) that would likely affect a smaller amount of streams and wetlands. 3. Minimum Release: The Certification for this project will require a minimum release in order to protect downstream uses including aquatic life. Please provide a proposed minimum release schedule for this project. We suggest that this flow be based on an updated Instream Flow Incremental Methodology (IFIM) analysis. 401 Oversight/Express Review Permitting Unit 1650 Mail Service Center, Raleigh, North Carolina 27699 -1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919 - 733 -1786 / FAX 919- 733 -6893 / Internet: http: //Uo.enr.state.nc.us/ncwetlands An Equal Opportunity/Affirmative Action Employer— 50% Recycled/ 10% Post Consumer Paper None Carolina N t ura!!y Cleveland County Sanitary Sewer District Page 3 of 3 August 23, 2005 4. Cumulative Impacts: You will need to conduct a qualitative analysis to examine the potential for cumulative impacts on streams, wetlands and water quality in the reservoir in accordance with the latest cumulative impact guidance that DWQ has provided. If this analysis shows that cumulative impacts are likely, then a quantitative analysis with proposed management plan will be required for the 401 Certification. Please contact John Dorney at 919 - 733 -9646 if you have specific questions in this regard. 5. Water quality in the proposed reservoir: The Division will require you to prepare an acceptable water quality model to address whether water quality standards will be met in the reservoir. Dissolved oxygen, temperature and eutrophication are issues that must be addressed by this model. DWQ will need to approve the model before it is used. Please contact Ms. Michelle Wookfolk (919- 733 -5083 ext. 505) for that review. This model should also reflect current water quality conditions in the First Broad River. Additional water quality sampling may be needed in order to address this issue if existing data are inadequate. This model should also address the effect of any additional development in the basin within a reasonable time frame. 6. Wetland impacts: The Public Notice states that wetland impacts are probably less than one acre. Please provide a signed delineation map from the US Army Corps of Engineers or similar assurance regarding the extent of wetland impacts. If impacts exceed one acre, then compensatory mitigation for wetland impacts will be required by DWQ. 7. Public Hearing: Please be aware that the Division has received several requests for a Public Hearing on this project. According to our rules (15A NCAC 2H .0503), the Director of the Division must decide whether to have a hearing based on the level of public interest. DWQ staff will seek this decision in the near future. If a Hearing is needed, additional correspondence will be sent to you. Please respond within three weeks of the date of this letter by sending this information to me in writing and Alan Johnson of the DWQ Mooresville Regional Office. If we do not hear from you within three weeks, we will assume that you no longer want to pursue this project and we will consider the project as withdrawn. This letter only addresses the application review and does not authorize any impacts to wetlands, waters or protected buffers. Please be aware that any impacts requested within your application are not authorized (at this time) by the DWQ. Please call Mr. John Dorney or Mr. Ian McMillan at 919 - 733 -1786 if you have any questions regarding or would like to set up a meeting to discuss this matter. hn Dorney Wetland P g m Development nit CBK/ /jrd /bs cc: Alan Johnson, DWQ Mooresville Regional Office Cleveland County Sanitary Sewer District Page 3 of 3 August 23, 2005 Dave Baker, USACE Asheville Regulatory Field Office File Copy Central Files Michelle Woolfolk, DWQ Michelle Raquet, DWQ John Sutherland, DWR Melba McGee, DENR Becky Fox, US Environmental Protection Agency Pam Boaze, Fish and Wildife Associates, Inc., P.O.

I have not yet had the opportunity to review the alternatives analysis that was sent out yesterday. EPA has provided numerous written and oral comments for this project and our comments have always stressed the need for a strong water conservation /reuse component for use in determining the projected water demand and in developing the alternatives analysis. Although the first objective listed in the project objectives section of the P &N section is to "develop an effective and efficient water supply system" there was little information in this section as to how the use of water efficiency measures was a component in projecting future water needs. Last week, I forwarded a draft paper to the FBRR project development team outlining EPA Region 4 guidelines that any applicant for a reservoir project in the Southeast will be required to utilize in developing water demand projections and alternatives analysis. Water efficiency measures have been shown to provide substantial and documented savings in water and money, and should not be dismissed as impractical and /or insignificant. The use of these measures are even more important in light of the current drought being experienced in the Southeast. EPA Region 4 places a very high priority on applying these measures in determining P &N and evaluating the alternatives analysis for reservoir projects, and recommends the applicant and the COE rigorously apply them in the development of the FBRR EIS. The discussion below is a follow up to the draft Region 4 paper and provides more information on efficiency measures we will expect to see addressed in the water needs projection and alternatives analysis for the FBRR. We believe water efficiency measures can and should be central to water supply planning. In comparison, large reservoirs can be very costly in both money and environmental impacts (and mitigation for environmental impacts), and lose very large amounts of water through evaporation. Water conservation measures should not be a policy enacted only in times of drought. The following discussion elaborates on some of the measures outlined in the EPA Region 4 drought measures guidelines paper: Stop leaks: Aged and broken pipes and valves can be responsible for huge quantities of water loss in water supply systems in the U.S. It is not clear from the P &N document if the Cleveland County Sanitary District (CCSD) utilizes a leak detection /repair program. Table 15 contains water loss information that shows an average of 17% unaccounted water loss per year for years 2003 -2007, but there was not a discussion of a water loss detection and repair program. The P &N section should contain a detailed discussion of what measures CCSD is using to determine unaccounted for losses of water and what type of leak detection and repair measures are being utilized. Although water losses may be 20% or higher in water supply systems across the country, we believe with advances in technologies and expertise, these losses should be able to be reduced to less than 10 %. Leesburg, VA was able to reduce their loss from 33 to 6% and is working on further reductions. Raleigh, NC, through a year round leak detection and abatement program, has been able to reduce their leakage rate to 4.5 %. This can represent huge savings in MGD of water usage. Leak detection and the impact of potential repairs to the water supply system should be incorporated into 3 of 8 2/17/2009 2:22 PM Re: EPA comments on Cleveland Co P &N statement the water demand projections for the FBRR project. There may be money available for this with the new Administration as part of an infrastructure repair component of the financial recovery plan. EPA can provide additional information on this as it becomes available. Water Price: Water should be priced to encourage conservation. This means water should be priced to cover what it actually costs to provide it to the consumer. A two -tier pricing system is recommended. This would include a flat fee to cover fixed utility costs and a second part variable fee that would charge higher rates as water consumption increases to above average levels to discourage waste and encourage conservation. Correct pricing for water has been estimated to be able to provide savings of around 15 %. Meter all Users: Generally multi - family units and commercial buildings charge a flat rate for water. This practice does not encourage users to conserve water. Individual user water meters should be installed on all new buildings and incentives should be provided to retrofit old buildings with individual metering. Retrofit all Buildings: Large water savings could be realized if all households and businesses used water efficient appliances and fixtures. Estimates are this could result in 20% savings. This could be accomplished in old buildings by mandating updates be made on resale or establishment of new accounts. Voluntary incentive programs such as rebates and free audits could also help with retrofitting older buildings. Landscape and Irrigation Systems: Large amounts of water usage can be attributed to landscaping (some estimates have it at 30 %). Municipalities have been able to greatly reduce this use through measures such as: dedicated irrigation meters for large landscapes with a significantly higher water rate, moisture /rain sensors for all irrigation systems, free irrigation system audits, use of different landscape models and plants that use less water. Smart New Buildings: All new buildings should require the most water efficient technologies. This should include the appliances and fixtures, and also dual plumbing systems that allow the use of gray water and harvested rain water for activities that do not require drinking - quality water, like toilet flushing or irrigation. Section 4.1.2 of the P &N section discusses future demands from new housing. These demand projections should be based on the use of efficiency measures in new housing and businesses and not on historical water usage data from houses and buildings not incorporating water efficiency technology and programs. These are just some of the ways water efficiency measures can result in large savings in water and costs. Revised water demand projections for this project should, at a minimum, reflect the incorporation of these and other measures outlined in the Region 4 drought management guideline paper. The demand projections in the P &N appear to be based on historical usage rates and should be updated to reflect the incorporation of the efficiency measures outlined above. Section 4.42 (Water Supply Needs) does not contain any mention of the incorporation of water efficiency /conservation measures. This should be a major component in this section. We will be looking for how each of these measures will impact the water demand projections in the revised Purpose and Need section. EPA Region 4 considers this a key component in the evaluation of not only the FBRR project but also all future reservoir projects in the Southeast. 4 of 8 2/17/2009 2:22 PM Re: EPA comments on Cleveland Co P &N statement Along with the incorporation of the efficiency measures, we are also providing the reminder that any other municipalities, towns, etc that are used to determine water projection demands should have a signed service agreement with CCSD. This information should be included in the P &N section.. We appreciate the opportunity to comment on the draft P &N section and look forward to being involved with this project as we move through the EIS development process.

Minor changes may be incorporated as project specifics allow. The intent of these meetings will be to inform resource agencies and other interested parties of the status of ongoing studies and issues, and to solicit individual comments from agencies and other groups about the major issues associated with the proposed action in a manner that is focused on specific issues or specific elements of the EIS. The purpose of these meetings is to complete the Corps' process in as open a manner as possible; at the same time, however, meetings will be held only if they continue to be helpful to the Corps and resource agencies in preparing its NEPA document. Specifically, the District intends to implement the following measures for its meetings: 1. Meetings will be focused on specific topics of concern. The purpose of scoping meetings is to disclose an applicant's preferences regarding a proposed project, discuss the Corps' proposed strategy for studying, analyzing, and documenting particular issues of concern, and solicit the individual comments of agencies and interested groups and parties regarding those preferences and strategies. Specifically, issues such as purpose and need, range of alternatives, mitigation, and cumulative and secondary impacts will be discussed, as will project -specific issues associated with proposed environmental impacts and necessary studies accomplished during the planning and permitting process. 2. Meetings will not be a public forum for opinion or comment on the project as a whole. The Corps solicits comments from the public on major projects through a variety of mechanisms, including public notices for all major permit applications received, public notices for draft and final EIS documents, and, as needed, public hearings. The purpose of scoping meetings, as opposed to these other opportunities for public comment, is to allow resource agencies and other concerned parties the opportunity to keep up with the scoping process as it progresses, and to provide comments and concerns related to specific topics of concern before the Draft EIS is released. 3. The purpose of the meeting is to both provide information and solicit input; it is not to reach consensus. The Corps seeks input from a wide array of interests as it compiles its EIS documents. It is highly unlikely that widely diverse interests will be able to reach consensus on any particular issue. The Corps' goal is to solicit the individual comments of each interested agency or party. The Corps will then decide on the appropriate course of action. 4. There is no particular "team" associated with this process; advice and comment are solicited from all interested parties, particularly those with regulatory responsibility for or expertise with particular areas of concern. All agencies with regulatory responsibility will be invited to participate. Others are welcome, although it must be reiterated that this is not a forum for general comments of support or opposition to the project. 5. Individual comments are welcome at all stages, and should be made in writing if at all possible. While notes of meetings will be kept, in order to assure that all comments are received accurately, the Corps asks that comments be made in writing. A list of comments will be kept, and comments will be responded to as appropriate. 6. Professional decorum is required at all scoping meetings. Those that do not respect the process will be asked to leave. If holding productive meetings becomes a challenge for any particular project, scoping meetings may be cancelled, and the public will be allowed the opportunity to comment through public notices on the permit application and the EIS. 7. Review Documentation and a summary of each meeting will be posted on the Wilmington District's Regulatory website. The District will provide a webpage that the public can access and review what documentation the agency/stakeholders have commented on and a summary of each meeting. We look forward to working with all parties in developing the EIS. If you have any questions or comments regarding this correspondence, please do not hesitate to contact Henry Wicker in the Wilmington Regulatory Division Office at 910-251-4930.

Introduction In accordance with the National Environmental Policy Act (NEPA) of 1969, as amended, a planning, environmental, and engineering study is underway to increase the water supply for Cleveland County Water. An Environmental Impact Statement (EIS) will be prepared to describe and evaluate potential impacts to the natural, cultural and human environments associated with the proposed action. This Purpose and Need Statement will comprise the first chapter of the EIS. The content of this document conforms to the requirements of Council on Environmental Quality (CEQ) regulations, which provide direction regarding implementation of the procedural provisions of NEPA. It is anticipated that any build alternative selected will require U.S. Army Corps of Engineers (USACE) permits; therefore, the USACE is the lead agency for the EIS. The EIS will be prepared by a third party in conformance with 33 CFR Part 325. 1.1 Proposed Action The proposed action is to construct a water supply reservoir in the First Broad River basin near Lawndale in Cleveland County, North Carolina. 1.2 Summary of Need for the Proposed Action It is projected that Cleveland County Water will need 6.23 million gallons per day (mgd) of raw water by 2060 to meet average day demands and 7.78 mgd to meet peak day demands (see Section 4.4.2). At the Cleveland County Water intake on the First Broad River, the estimated available raw water supply under low flow conditions is 5.97 mgd (see Section 2.4.1). Historical records from 1940 through 2008 were used to assess the ability of Cleveland County Water's existing run -of -river intake to supply future raw water needs. Depending on the minimum instream flow requirement, the future demand of 7.78 mgd would not be met on 9.7 percent of the days (2,420 out of 24,954 days). Of these, as many as 110 days would be consecutive. Water shortages lasting at least 10 consecutive days would occur 4.2 percent of the time (see Section 4.4.3). The First Broad River is insufficient to meet projected demands, based on the following conditions: Fluctuations in the normal stream flow of the First Broad River vary widely and affect water availability at the Cleveland County Water intake on a daily basis. Cleveland County suffered a severe drought that peaked in 2002. The county is experiencing another drought in 2008 and is susceptible to future droughts. A long-term solution is needed to ensure adequate drinking water, especially during drought conditions. Groundwater is not a reliable source of water in the Cleveland County area, as wells either run dry or have low water levels. Water quality is also a concern. It is estimated that approximately 8,000 housing units (approximately 20,240 persons) rely on individual groundwater wells as the sole source of potable water. It is expected that most of these residences will become Cleveland County Water customers through the planning period (2060). The population of Cleveland County Water's current service area is projected to increase by approximately 6,000 persons by 2060. It is expected that these new residents will be Cleveland County Water customers. • Based on continuing requests for service connections, it is evident that the need for a dependable source of potable water does not stop at the county line. Cleveland County Water already serves approximately 500 customers in Gaston, Lincoln and Rutherford counties. Cleveland County Water plans to expand its service area in areas that can be more easily and economically served by Cleveland County Water rather than existing water systems in these counties. 1.3 Purpose of the Proposed Action The purpose of the proposed action is to ensure a dependable water supply for Cleveland County Water that meets projected long-term (2060) needs. A "dependable" water supply will provide the district's needs and maintain required instream flows (assuming water conservation measures are implemented in accordance with an approved drought management plan). Draft Purpose and Need Report First Broad River Reservoir 2 Draft Purpose and Need Report First Broad River Reservoir 1.4 Project Objectives Key project objectives, applicable to the Cleveland County Water service area, include the following: • develop an effective and efficient water supply system; • provide adequate water infrastructure that supports population growth and economic development; • maintain sufficient instream flow to support aquatic habitat and other uses; • sustain required instream flow levels for downstream users; and • respond to the needs of existing and future water customers. 1.5 Project Setting Cleveland County is located in the southwestern Piedmont of North Carolina in the foothills of the Blue Ridge Mountains. Cleveland County is bordered by Gaston and Lincoln counties on the east, Burke County on the north, Rutherford County on the west, and South Carolina to the south. The primary transportation route is US 74, which traverses the county in an east -west direction, connecting Interstates 85 and 26. Interstate 85 traverses the southeastern corner of Cleveland County. Shelby, the largest municipality in the county, is the county seat. Other municipalities include Kings Mountain, Boiling Springs, Belwood, Casar, Earl, Fallston, Grover, Kingstown, Lattimore, Lawndale, Mooresboro, Patterson Springs, Polkville, and Waco (see Figure 1). The largest cities or towns, Shelby, Kings Mountain, and Boiling Springs, are concentrated on or near the US 74 corridor. Despite the number of incorporated towns, Cleveland County remains relatively rural overall. In 2000, most of these municipalities had a population below 1,000 according to U.S. Census data. (See Population and Demographic Trends, Section 4.1.) 1.6 Water Resources Most of Cleveland County is located in the Broad River Basin. A small area of eastern Cleveland County is in the Catawba River Basin (see Figure 2). In North Carolina, the Broad River Basin encompasses a 1,513 square mile watershed with headwaters in Draft Purpose and Need Report First Broad River Reservoir the mountains. The First Broad, Second Broad, and Green rivers are the major tributaries of the Broad River. The First Broad River originates in Rutherford County and flows into the Broad River in Cleveland County, just north of the South Carolina border. The Broad River flows southeast into South Carolina, eventually flowing into the Atlantic Ocean as the Cooper River at Charleston, South Carolina. 1.6.1 Sub -Basin 03-08-04 The Broad River Sub -basin (03-08-04) includes approximately 240 square miles and encompasses the project area and approximately two-thirds of Cleveland County. Land within this sub -basin is the transitional zone between the mountain and piedmont eco -regions. According to the 2006 Basinwide Assessment Report for the Broad River, land cover in this sub -basin is primarily forested (63 percent forest/wetland) and pasture (31.2 percent pasture/managed herbaceous). Urbanized areas account for 2.7 percent of the land area in the sub -basin, while cultivated cropland includes 2.0 percent of the land area in the sub -basin. e North vision Water uality thhs sub -bas nr sllgo dl overallf Benthic�rnacroiNveDebQrate data reports from threewater sitesltonithe Deleted: macro invertbrate First Broad River resulted in "Good" bioclassifications. None of the surface waters in this sub -basin are considered to be impaired. 1.6.2 Sub -Basin 03-08-05 The Broad River Sub -basin (03-08-05) includes approximately 181 square miles and encompasses most of eastern Cleveland County. This area is considered to be in the piedmont eco -region, although some streams in the northern portion of the watershed exhibit some mountain characteristics. Land use is dominated by forest and agricultural activities (48.5 percent forest/wetland and 40.5 percent pasture/managed herbaceous). While urban uses account for only 5.1 percent of total land cover, residential development is increasing. Kings Mountain is the largest urban area in the sub -basin. The NCDWQ reports that water quality in this sub -basin is good overall. None of the surface waters in this sub -basin are considered to be impaired, although some water quality issues have been documented. 4 Draft Purpose and Need Report First Broad River Reservoir 1.7 Project History In 1989, the North Carolina Division of Water Resources (NCDWR) prepared the Cleveland County Water Supply Study, at the request of the Cleveland County Board of Commissioners. The study was prepared, in part, to project future water needs and determine if future water needs (2030) will exceed existing supplies. The study determined that existing systems were adequate to meet 2020 needs, with the exception of the Town of Boiling Springs' well system. The town is now connected to the City of Shelby's system. The study suggested that raw water supply availability may be increased through capital improvements, such as reservoirs and off stream storage. The possibility of an impoundment on the First Broad River has been explored for a number of years. The USACE studied a potential reservoir on the First Broad River in 1990. It was determined that a reservoir was not feasible for flood control purposes; however, a reservoir might be feasible for water supply purposes (USACE 1990). The 1995 Cleveland County Land Use Plan, adopted by the Cleveland County Board of Commissioners in November 1995, included the following recommendation: "Support the development of a 50 million gallon raw water reservoir for the Cleveland County Sanitary District." A feasibility study for the First Broad River Reservoir was completed by McGill Associates in 1997. The study concluded that a reservoir would be needed by 2029 and recommended an impoundment on the First Broad River (McGill 1997). The water shortages experienced during the 2002 drought demonstrated the need for a more dependable water supply. Since that time, Cleveland County Water has continued to work towards this goal. Additional information about drought conditions is provided in Section 2.4.2.3. The adopted 2005 Cleveland County Land Use Plan notes that a reservoir site has been chosen and the project is in the environmental permitting stage. The 2005 plan's Land Use Plan Map shows a reservoir site. Draft Purpose and Need Report First Broad River Reservoir 2. Cleveland County Water 2.1 Background 2.1.1 Sanitary Districts in North Carolina Cleveland County Water was established under North Carolina statutes as a sanitary district. In North Carolina, a sanitary district is a special governmental unit created for the purpose of preserving and promoting the public health and welfare. A sanitary district is formed with the consent of a majority of property owners in the proposed district. The North Carolina Commission for Public Health and the Board of Commissioners of the county (or counties) where the proposed district is located create the sanitary district by adopting an ordinance setting the corporate boundaries of the district. According to North Carolina general statutes (G.S.), a sanitary district may be established without regard for county, township or municipal lines. (However, approval by a municipality is required before including any part of a municipality in the sanitary district.) A sanitary district has the power to acquire, construct, maintain and operate water supply systems and water purification or treatment plants and other utilities "within and outside the corporate limits of the district, as may be necessary for the preservation of the public health and sanitary welfare outside the corporate limits of the district, within reasonable limitation" (G.S. 130A-55). Corporate powers set by North Carolina statutes also include the power to levy taxes on property within the district; to acquire by purchase or condemnation, property, easements, and rights-of-way inside or outside the district; to negotiate and enter into agreements with other water suppliers in order to carry out the purpose of the sanitary district. A sanitary district has the authority to levy taxes only within its corporate boundaries but the sanitary district may set a different rate for customers inside and outside the corporate boundaries of the district. The statutes also set provisions for expanding the corporate boundaries of a sanitary district. A complete list of corporate powers of a sanitary district is included in G.S. 130A-55. 2.1.2 History of Cleveland County Water Cleveland County Water was established in accordance with state statutes as the Upper Cleveland County Sanitary District in 1980. In 1984, the Upper Cleveland County Sanitary District started supplying water to 1,200 customers. By the late 1980s, the Piedmont Metropolitan Water District had formed in southern Cleveland Draft Purpose and Need Report First Broad River Reservoir County to address dry wells and poor water quality in the southern portion of the county. The two districts merged in 1989 to form the Cleveland County Sanitary District. By 1990, the sanitary district was serving 16,800 customers with 5,600 meters. In February 2008 upon approval of the North Carolina Commission for Health Services, the Cleveland County Sanitary District changed its name to Cleveland County Water. In July 2008, Cleveland County Water was providing water to approximately 45,155 residential customers with 18,374 active meters. With approximately 3,000 inactive meters also on the system, the total number of residential customers could increase to over 52,700. Cleveland County Water covers approximately 80 percent of the geographic area of the county and is one of the fastest growing water providers in North Carolina. Cleveland County Water has averaged 520 new taps per year since 1999 and this trend is expected to continue over the next 5 years. 2.2 Facilities 2.2.1 Existing Facilities Cleveland County Water uses the First Broad River as the source for a 6.0 mgd water plant. Cleveland County Water operates raw water intakes and a pump station at the confluence of the First Broad River and Knob Creek. The raw water intake facility can withdraw a maximum of 10 mgd from the First Broad River and Knob Creek. The current average daily withdrawal is 3.70 mgd. The distribution system includes approximately 1,000 miles of water lines and several finished water storage tanks. In addition, Cleveland County Water has emergency connections with Kings Mountain; Shelby; the Broad River Water Authority; and Grassy Pond, a small system in southern Cleveland County. 2.2.2 Planned Facilities Cleveland County Water plans to expand its water treatment plant capacity in anticipation of system growth. As the first phase of water treatment plant expansion, Cleveland County Water plans to build off -stream storage sized to accommodate a 10 mgd water treatment plant. This off -stream storage is required by state code in order to provide an unpolluted storage reserve in the event of contaminant spills. With a capacity of 50,000 gallons per day (gpd), the off -stream storage will provide a 5 -day supply of water. Planned for construction in 2009, the storage facility has been permitted by the USACE (permit number 200531774). The next steps in the phased Draft Purpose and Need Report First Broad River Reservoir expansion are to expand the filters to 8 mgd by 2010 and expand distribution pumps to 10 mgd by 2011. By 2012, Cleveland County Water plans to upgrade the water treatment plant capacity to 8 mgd and eventually to upgrade the plant to 10 mgd. 2.3 Service Area 2.3.1 Existing Service Area Cleveland County Water provides water to most rural areas of the county; the towns of Belwood, Casar, Earl, Kingstown, Lattimore, Mooresboro, Patterson Springs, Polkville, and Waco; and on a contract basis to the town of Fallston. Cleveland County Water also has lines extending into Gaston, Lincoln, and Rutherford counties. Cleveland County Water has connections extending to Boiling Springs, Fallston, and Lawndale for emergency use. The Cleveland County Water service area boundary is based on topography and the hydraulic grade line of the distribution system, which includes existing finished water storage tanks. Cleveland County Water's service area is shown in Figure 3. 2.3.2 Future Service Area As evidenced by the existing service area and requests from property owners, the need for water does not stop at the Cleveland County line. Cleveland County Water plans to continue to expand its distribution system into areas of Rutherford, Lincoln, and Gaston counties which can be more easily and economically served by Cleveland County Water rather than existing water systems in these counties. Future service area is shown on Figure 3. Cleveland County Water owns a water storage tank in northern Cleveland County near Casar; as well as a smaller water storage tank on Moriah School Road near the Rutherford County line. These tank locations allow for service into the northern part of Rutherford County. Near the Polkville area of Cleveland County, Cleveland County Water owns a tank which provides water service to the areas of Cleveland County west of the First Broad River. The location of this Polkville tank and the hydraulic service area provided from the tank also permits economical service into the eastern part of Rutherford County. The boundary for the Rutherford County future service area is based on topography and resulting hydraulic constraints and existing service areas for other water providers in the county. For example, in the northern part of Rutherford County, Cherry Mountain, located southwest of NC 226, provides a natural drainage boundary between the First Broad River to the east and the Second Broad River to the west. This natural geographic boundary makes the provision of water service farther westward uneconomical due to hydraulic constraints. Generally, the Rutherford County expansion area stretches from just north of the First Broad River to the Second Broad River to the south. The western boundary follows ridge lines and property lines. Future water service to the east of this boundary is not feasible and water service to the west of the boundary will be provided by existing water systems located in Rutherford County, either the BRWA, the Town of Ellenboro or the Town of Forest City. Future service to the east of Cleveland County by Cleveland County Water into Lincoln and Gaston counties is limited by system hydraulics similar to those described above. The eastern service area boundary in Lincoln County and Gaston County as shown on the "Service Area" map (Figure 3) is the ridge line between the Broad River Basin and the Catawba River basins. Future service into these two adjoining counties is proposed entirely within the Broad River Basin and outside the Cherryville city limits. 2.4 Water Supply and Availability 2.4.1 Available Raw Water Supply An updated 7Q10 was used as a basis for determining available raw water supply. While changes in low -flow characteristics resulting from recent drought conditions have not been formally investigated by the U.S. Geological Survey (USGS), updated values are likely to be 20 to 30 percent lower than previously reported values according to the USGS (Weaver 2008). To determine a revised 7Q10 at the Cleveland County Water intake (181 square miles), the 7Q10 for the Knob Creek drainage area (36 square miles) was added to the 7Q10 for the First Broad River drainage area (145 square miles). Updated 7Q10 values were determined as follows: First Broad River In June 2008, NCDWR updated an instream flow/aquatic habitat study,completed in the 1990s for three locations on the First Broad River. A major revision to the previous study was to include updated and improved stream flow record. Based on merged flow Draft Purpose and Need Report First Broad River Reservoir Comment [N1]: Why not perform a new 7Q10 analysis for the Casar gage? Even though it would not be "official" it is better than assuming it is 20 or 30%. Deleted: records from the Lawndale and Casar USGS gaging stations, the 7Q10 just downstream of the Cleveland County Water intake was determined to be 36.4 cubic feet per second (cfs), at a drainage area of 145 square miles. This 7Q10 value reflects the lower flows during periods of drought experienced in recent years. Knob Creek In the absence of an instream flow study, the 7010 for Knob Creek is based on USGS records for a similar upstream site. (According to the USGS, it would be appropriate to use the 7Q10 estimate at this site for application to the Knob Creek intake site [Weaver 2008].) To account for recent drought conditions, it was assumed that the 7Q10 has declined by 30 percent. The updated 7Q10 for the Knob Creek drainage area is estimated to be 9.84 cfs, at a drainage area of 36 square miles. Therefore, the estimated 7Q10 is 46.24 cfs at the Cleveland County Water intake site. Based on the new 7Q10 calculation, the available raw water supply (defined by regulation as 20% of the 7Q10) from the First Broad River at the Cleveland County Water intake is estimated to be 9.25 cfs or 5.97 mgd. 2.4.2 Issues Affecting Water Supply The river's capacity to supply water to Cleveland County Water is substantially affected by other demands on the river and by fluctuations in the normal stream flow. Downstream from the Cleveland County Water intake, the City of Shelby also relies on the First Broad River for water; therefore, downstream conveyance to the city's intake is a concern. The First Broad River is also needed for wastewater treatment discharges, mainly for the City of Shelby, and for agricultural irrigation purposes. An instream flow is also required to sustain the aquatic community within the river. Other instream uses for water can include water quality maintenance and prevention of sediment build-up. Draft Purpose and Need Report First Broad River Reservoir Iff Draft Purpose and Need Report First Broad River Reservoir 2.4.2.1 Aquatic Habitat The NCDWR determines flow requirements for streams to ensure aquatic habitat protection, particularly during dry season flows. The aquatic habitat target flow, was determined to be 70 cfs (45.16 mgd) at the previous Cleveland County Water intake (Sutherland 1992). Cleveland County Water was allowed to take 5 mgd without instream flow limits, but could take an additional amount up to a total of 6 mgd if a flow of 70 cfs was maintained immediately downstream of the intake. At the current intake location, no minimum flow or withdrawal constraint is required (Sutherland 1997). 2.4.2.2 National Pollutant Discharge Elimination System Point source dischargers located throughout North Carolina are regulated through the National Pollutant Discharge Elimination System (NPDES) program. The NPDES program was established to control point -source discharges of water pollution. Dischargers are required by law to register for a permit. The permitting process includes determining the quality and quantity of treated wastewater that the receiving stream can assimilate, incorporating input from stream modeling, collaborating with NCDWQ Regional Office staff, and evaluation of the discharger's location. According to NCDWQ, there are eleven permitted dischargers within the 03-08-04 sub - basin, three of which are considered major dischargers. Of the eleven dischargers, the City of Shelby Waste Water Treatment Plant (major), the City of Shelby Water Treatment Plan (minor), Cleveland County Water (minor), and an industrial facility (major) discharge to the First Broad River. The first Broad River plays an important role in the disposal of wastewater. 2.4.2.3 Drought Conditions Water systems such as Cleveland County Water that rely on run -of -river type intakes are particularly susceptible in drought conditions. The drought that Cleveland County 'According to the Cleveland County Water Supply Survey (NCDWR 1989), instream target flows are based on maintaining one dominant instream use or a combination of uses. During those times when natural flows are below the target flow, projects capable of flow augmentation should maintain the target flow, while others without flow augmentation should use the naturally occurring flow as the temporary target. experienced from 1999 to 2002 highlighted the need for a more dependable water source. The drought was so severe that Governor Michael Easley declared a State of Disaster and State of Emergency existed in the Cleveland County Water service area and the City of Shelby. Cherryville, located in Gaston County to the east, was also named in the proclamation. In addition, local proclamations were issued by Cleveland County, excluding the City of Kings Mountain, and by the City of Shelby. In July and August of 2002 the flow at the Cleveland County Water intake dropped to 3.0 mgd (McGill 2004). Also during that time, the available supply at the City of Shelby water intake dropped to less that 1.50 mgd (McGill 2004). As a result, water restrictions were imposed and Cleveland County Water and the City of Shelby were forced to find alternative means to provide water to their customers. To provide some relief, the Broad River Water Authority allowed an emergency connection to the Cleveland County Water system. However, this connection could only supply water to approximately 200 customers because of the six-inch pipe size and the difference in elevation of the two systems' tanks. Even during drought conditions, Moss Lake provided more than adequate supply of water to the Kings Mountain service area. The City of Kings Mountain was able to provide water to Shelby customers through an emergency connection with the City of Shelby water system. This connection is to provide water only during periods of a declared emergency. Shelby also pumped water from a small privately owned lake, and implemented water restrictions in order to continue to supply water to their customers during the drought (McGill 2004). To prepare for future drought conditions, the City of Shelby installed an emergency 30 -inch water line to the Broad River after the 2002 drought. However, it should be noted that the Broad River is also at risk during drought conditions and the location of the intake requires water to be pumped. As the demand for water in the Cleveland County Water and City of Shelby service areas increases, Moss Lake will not be sufficient to supply these areas during drought. Droughts also occurred in the area in 1977 and 1986 (Cawthon 2005) and the area is currently in drought in 2008. According to the U.S. Drought Monitor, Cleveland County is experiencing exceptional drought in August 2008. While the area has not yet experienced the degree of water shortage as those experienced during the drought that peaked in 2002, water levels have been a cause for concern. Such concerns are documented in news articles published in the Shelby Star in the summers of 2005 (Cawthon 2005) and 2006 (DeLea 2006), and again in June 2008 (Wilson 2008). Large amounts of rainfall that occur in relatively short periods of time are not helpful towards easing drought conditions because there are no provisions for capturing water. Draft Purpose and Need Report First Broad River Reservoir 12 Steady rains over a longer period of time are needed to restore the water table and increase stream flows. 2.4.2.4 Run-of-Riverintake Of the 32 water providers in North Carolina serving a population of 40,000 or more, 16 depend on reservoirs as their primary water source, while three depend on groundwater. The remaining 13 water providers, including Cleveland County Water, depend on run -of -river type intakes for water supply (see Table 1.) These intakes are located on the Cape Fear River (Fayetteville, Wilmington, Harnett County, Brunswick County, Sanford), Yadkin River (Davidson, Salisbury), Tar River (Greenville), Neuse River (Johnston County), Catawba River (Union County), and the First Broad River (Cleveland County). With the exception of the First Broad River, these are considered major rivers in North Carolina. Table 2 compares the size of watersheds and river volume for these water systems. Based on data from the gage at Casar, the First Broad River in proximity to the Cleveland County Water intake has the lowest mean and median flow. Even in non -drought conditions, fluctuations in the normal stream flow can vary widely and affect available water on a daily basis. The USGS maintains a surface water gaging station on the First Broad River near Casar. For illustrative purposes, annual discharge data beginning in 1960 is included in Table 3. As the table indicates, annual discharge during the 45 -year period varied from a high of 139.3 cfs (89.9 mgd) in 1960 and 1975, to a low of 26.8 cfs (17.3 mgd) in 2002. A breakdown of this data by month further illustrates the variation in flows of the First Broad River (see Table 4.) Daily flows are recorded by the Casar gage beginning March 1, 1959. Daily records are available on the USGS website: http://waterdata.usgs.gov/nwis. 3. Other Area Water Sources The existing sources of potable water in Cleveland County are Moss Lake, the First Broad River, and groundwater. The Broad River is a source of limited drinking water during emergencies. Water sources and providers for Cleveland County are shown in Table 5. 3.1 John H. Moss Reservoir The John H. Moss Reservoir (Moss Lake), an impoundment on Buffalo Creek, is the raw water supply for the City of Kings Mountain and the Town of Grover. Moss Lake Draft Purpose and Need Report First Broad River Reservoir 13 has a total drainage area of approximately 68 square miles in eastern Cleveland County. The City of Kings Mountain operates an 8.0 mgd water treatment plant adjacent to the lake. The city provides water only within its corporate limits and to its municipal customer, the Town of Grover. However, the city permitted the construction of an emergency connection with the City of Shelby water system during the 2002 drought to provide water only for emergency purposes. According to the city, the water provided by Moss Lake is sufficient to meet demands of its service area through 2050 and beyond. In 2007 Kings Mountain permitted the construction of an emergency connection with Cleveland County Water. 3.2 First Broad River In addition to Cleveland County Water, the First Broad River is also the water source for the City of Shelby, the Town of Boiling Springs. (Boiling Springs purchases water from Shelby.) The City of Shelby has a raw water intake on the First Broad River which supplies water to the city's water treatment plant. Treatment facilities include three off -stream raw water reservoirs. The intake location has a drainage area of approximately 226 square miles. Shelby's water treatment plant has a capacity of 12.0 mgd and current average daily water treated is 4.2 mgd. Demand has decreased in recent years as several manufacturing plants in the city have closed. Current (2005) peak demand is approximately 6 mgd compared to 8 to 9 mgd in past years (City of Shelby Strategic Growth Plan 2005). The City of Shelby provides water on a wholesale basis to the Town of Boiling Springs. The contract amount in 2002 was 1.0 mgd (Shelby Water Supply Plan 2002). The City of Shelby Water and Wastewater Planning Report sets a future water service area boundary that extends beyond the current city limits. Shelby's water system is encircled by the Cleveland County Water service area, which limits the ability of the city to expand its water system. Expansion of Shelby's water service area and annexation in areas already served by Cleveland County Water could affect the district's customer base to some degree. According to the city's Strategic Growth Plan, "when the city annexes new areas, it can not take these annexed homes and businesses into its water system customer base." However, according to Brad Cornwell, Shelby Public Utilities Director, "the city can require connection to the public water system if the building or structure is within 300 feet of such public water main and the property abuts a street where a public water Draft Purpose and Need Report First Broad River Reservoir Comment [N2]: Are more recent 11 data available? If so, has the I downward trend continued, l leveled off, or increased? 14 main is available" (Cornwell 2007). There is no city policy to specifically address annexation of areas served by Cleveland County Water. In the past, the city has chosen not to provide water in most cases where the annexed area is already served by Cleveland County Water, but reserves the right in the future to construct water facilities if it is feasible (Cornwell 2007). At a minimum, the city is required to provide increased flows for fire protection to these annexed areas. Based on the City of Shelby's 2002 Water Supply Plan, average daily water demands for the city's service area are projected to be 8.7 mgd by 2050, including contract sales of 1.0 mgd. Assuming an average day to peak day multiplier of 1.25, approximately 10.88 would be needed in 2050. 3.3 Groundwater In Cleveland County, the primary problem associated with dependence on groundwater as a source for potable water is a natural shortage in water, with either very low water levels in wells or wells running dry. It is sometimes necessary to drill several wells before finding water (North Carolina Division of Water Resources 1989). Property owners have to assume the risk and cost of drilling dry wells in their search for a suitable yielding well. It is more cost effective to connect to a water system if available. Water quality is also a problem. For example, residents of the Town of Mooresboro relied on wells as their source for potable water prior to 2005. Many residents had to bleach their well water to sanitize it, and in 2003 E. coli bacteria were discovered in 6 of 11 wells tested (Scott 2004). Also, some wells ran dry during the 2002 drought. The town was connected to the Cleveland County Water system in 2005. In some areas of the county, both recharge and discharge areas display high concentrations of iron and manganese in the groundwater. Water treatment for these metals is necessary (North Carolina Division of Water Resources 1989). Where iron or manganese is not a problem, the groundwater may require chlorination. In addition, lithium has been detected in groundwater in the Cherryville and Bessemer City vicinity of Gaston County. (Cleveland County Water already has nearly 100 customers in Gaston County.) Costs associated with water treatment, whether for a municipal system or individual well, are ultimately borne by the end user. Additional treatment can potentially be a significant expense (Setzer 2007). Draft Purpose and Need Report First Broad River Reservoir E, Draft Purpose and Need Report First Broad River Reservoir 3.3.1 Municipal Systems The towns of Lawndale and Fallston rely on groundwater for their primary water supply. Lawndale draws its water supply from two wells with a combined average daily withdrawal of 0.058 mgd for 287 connections (Lawndale Water Supply Plan 2002). In the Town of Fallston, three wells provide an average daily withdrawal of 0.046 mgd. Fallston supplements this supply with water purchases from Cleveland County Water. In 2002, the average daily amount provided to Fallston was 0.001 mgd, with a contract amount of 0.002 mgd, according to the draft 2002 Fallston water supply plan. 3.3.2 Private Wells Groundwater is the water source for numerous residences throughout rural Cleveland County. However, very little data is available regarding private wells in the county. Until recently, Cleveland County did not require permits for private wells and the county Health Department inspected wells only upon request. In July 2006, the state of North Carolina mandated that all counties adopt drinking water well regulations. House Bill 2873 requires all North Carolina counties to implement a private drinking water well permitting, inspection, and testing program. As a result, Cleveland County adopted "Rules Governing the construction, Inspection, Repair, Abandonment, and Water Quality Testing of Private Drinking Water Wells in Cleveland County." The ordinance was effective July 1, 2007. It is estimated that approximately 8,000 housing units in Cleveland County rely on groundwater for potable water. A number of these have a metered connection to the Cleveland County Water system; however, the meter is inactive. In 1992, the county began requiring new residences to tie on to Cleveland County Water lines if they were available (McCarter 2006). 3.4 Broad River In Cleveland County, the Broad River is not currently used as a water source for everyday use. The City of Shelby has an emergency 30 -inch raw water line from the Broad River to its water treatment plant. The raw water line and a pumping station were constructed as a result of the 2002 drought, as mentioned in Section 2.4.2.3. Cleveland County Water is also equipped to obtain small quantities of water from the Broad River in emergencies. In Rutherford County, the Broad River is the primary water source for the Broad River Water Authority. Several municipalities, including Forest City and some in South Carolina, plan to use the Broad River as a water source. 4. Water Demand Increases in future water supply needs for Cleveland County Water will be affected by new customers in the existing service area and service area expansion into adjacent counties. Within the existing service area (Figure 3), new metered connections are expected due primarily to well conversions and population growth. As discussed in Section 2.2.3, groundwater is not expected to be a reliable source of potable water in Cleveland County. Groundwater quality and drought conditions (wells drying up) will likely result in increased demand for water from Cleveland County Water. Population trends and economic conditions that may affect population growth in the county and the type of users (e.g., commercial and industrial users) are discussed in the following sections. Cleveland County Water's service area and future demand will also be influenced, but to a lesser degree, by annexation and government policies. For example, as discussed in Section 2.2.1, it is the policy of the City of Kings Mountain not to provide water outside its corporate limits (other than to the Town of Grover.) In addition, recent state legislation requiring county well inspection programs could result in more requests to connect to Cleveland County Water's system. As previously noted, Cleveland County Water provides water to some customers in adjacent counties. The sanitary district plans to continue to expand its service area into these counties as requested. Demand in these areas will also be largely based on population growth and problems with groundwater. Cleveland County Water's future service area expansion in adjacent counties is shown in Figure 3. 4.1 Population and Demographic Trends 4.1.1 Population Growth Cleveland County experienced moderate population growth of approximately 14 percent from 1990 to 2000. Historical population data indicate similar growth rates in the 1960s and 1970s, but a substantially lower growth rate in the 1980s of less than 2 percent (see Table 6). While U.S. Census data indicate substantial growth in municipal population from 1990 to 2000, some of that growth is due to expansion of corporate Draft Purpose and Need Report First Broad River Reservoir Comment [N3]: This section is the crux of the document. It would benefit from a series of clear statements explaining exactly how future water demand was calculated. For example, in Section 4.1 data population data are presented from US Census Bureau and NC Demographics, but it is not clear if both data sets were used to estimate the future population. If, as stated in Section 4.1.3, the NC Demographics numbers were used, explain why they were used instead of US Census Bureau numbers. It is stated in Section 2 that those parts of adjoining counties that lie outside the Broad River basin will not be served by CCW. Section 4 should explain how the population data for those counties was used to project future demand. For example, it is not likely that the census tracts follow the basin boundaries. So, how were the demographic data for western Lincoln and Gaston counties used to project population estimates in the CCW service area? Comment [N4]: The Census Bureau has more recent data than 2000. The 2000 data is considered a census, but they also have annual, population estimates up to 2007. Do those data lead one to different estimates of future population? 17 limits. Shelby, in particular, can attribute most of its population gain during that period to an aggressive annexation program. An examination of population growth by census tract indicates that the highest population growth occurred in the southern and eastern areas of the county, with population declines in the central areas of Shelby and Kings Mountain. A breakdown of 1990 to 2000 population growth by municipality and census tract is provided in Tables 7 and 8, respectively. Census tracts are shown on Figure 4. From 1990 to 2000, approximately 4,066 county residents were added to the Cleveland County Water service area. Population growth in the service area was estimated by excluding population in Shelby, Boiling Springs, Kings Mountain, and Grover from the overall county population. (Note: Fallston and Lawndale were included in the service area because these municipalities use groundwater and are potential Cleveland County Sanitary District customers.) 4.1 .2 Housing The increase in housing units is another indicator of water demand. The number of housing units in Cleveland County increased by nearly 18 percent (6,085 units) from 1990 to 2000 Table 9). The number of housing units added in the Cleveland County Water service area over this same time period is estimated to be 2,710 units Table 9). Like population growth, the increase in the number of housing units in Shelby is largely due to annexation. The greater increase in the percentage of housing units as compared to population increase could indicate a trend in the reduction of household size or an increase in the supply of vacant housing during this period. According to the US Census, the average household size for Cleveland County in 2000 was 2.53 persons, while the average household size in 1990 was slightly higher at 2.59. In addition, the percentage of vacant housing rose from 6.4 percent to 8.1 percent of total housing during this period. A breakdown of 1990 to 2000 housing units by state, county, and municipality is provided in Table 9. 4.1.3 Population Projections The North Carolina State Demographics Unit (Office of State Management and Budget) projected county populations through 2030. Population through 2060 was projected using an average annual growth rate based on the state's projected growth from 2005 through 2025. It was assumed that each county would experience this same average growth rate over the next 30 years through 2060.1 Draft Purpose and Need Report First Broad River Reservoir Comment [N5]: Other than the number of people per house, how were the housing data used to project future demand? Please explain how housing data (Table 9) were used to calculate future water demand (Table 17). If not, this section could be deleted. Comment [N6]: This is a major assumption that could be way off. It is a good reason for projecting a +/- percentage around that estimate to understand the water needs under different scenarios. Ji 18 Population growth in Cleveland County will continue to be influenced by proximity to major metropolitan areas, the Charlotte -Gastonia area in particular, and proximity to major transportation routes. Within Cleveland County, population growth is expected to a greater extent in the southern and southeastern portions of the county. The North Carolina State Demographics Unit projects that Cleveland County will grow by approximately 2.24 percent from 2010 to 2030, reaching a population of 99,370 by 2030. In comparison, the state of North Carolina is expected to grow by approximately 29 percent during the same 20 -year period. Assuming a constant growth rate for the next 30 -year period, Cleveland County's population would reach nearly 103,000 by 2060. In addition to growth in Cleveland County, growth in the adjacent counties of Rutherford, Lincoln and Gaston will also play a role in future demand in the Cleveland County Water water supply. The North Carolina State Demographics Unit projects that Rutherford County's population will decrease by approximately 600 persons or 1 percent from 2010 to 2030. During the same period, Gaston County's population is expected to increase by approximately 13.5 percent, while Lincoln County's population is expected to increase by nearly 34 percent.', Population projections are shown in Tables 10 and 11. 4.2 Economic Characteristics 4.2.1 Economic Base Cleveland County is ranked one of the top ten best small markets by Southern Business and Development magazine (Charlotte Regional Partnership 2006). The county boasts easy access from four major interstate highways (1-85, 1-77, 1-26, and 1-40) and the Charlotte Douglas International Airport, making geography one of its prime assets. Although Cleveland County's economy was once dependent upon textile manufacturing, the county's economy is diverse, with no dependence on any one industry. From 1995 to 2005, manufacturing jobs in the county decreased by 7,609 jobs; however, manufacturing still dominates in terms of number of jobs. Employment by industry is shown in Table 12. Draft Purpose and Need Report First Broad River Reservoir Comment [N7]: The majority of growth in Lincoln and Gaston will most likely be in the eastern and central portions; less so in the western parts of those counties. Was this taken into account? Comment [N8]: A major shortcoming of this document is that it does not explain exactly how the population data and the housing data were used/combined to make projections into the future. Please provide text to explain this and give a mathematical example from start to finish. Comment [11419]: All this is interesting, but again, how were these data used to project future demand (i.e., in Table 17). Comment [114110]: How much has 1 this been further reduced in the past year? Please provide data through 2008. 19 4.2.2 Employment Centers and Major Employers According to the North Carolina Department of Commerce, the top manufacturers in Cleveland County include PPG Industries Fiberglass Products, Eaton Corporation, and Entertainment Distribution Company. The top non -manufacturing employers in Cleveland County are Cleveland County Schools, Cleveland Regional Medical Center, Cleveland County government, and Gardner -Webb University. Cleveland County's top employers are listed in Table 13 As indicated on Table 13, the county's employment centers are primarily in and around the cities of Shelby and Kings Mountain. In addition, major retail centers are the Cleveland Mall in Shelby and the uptown Shelby, Kings Mountain, and Boiling Springs areas. There are several major industrial parks in Cleveland County. The Cleveland County Industrial Park is located in Kings Mountain. The 250 -acre park is home to Sara Lee Intimate Apparel, which recently expanded; MRA Industries; and Owens & Minor. Cleveland County recently assembled a 210 -acre industrial park to help with industrial recruitment efforts in the county. The site has rail access and is located near the proposed US 74 Bypass, just west of Shelby. The North Carolina Department of Commerce is currently marketing 18 buildings and 45 sites in Cleveland County for commercial or industrial use. According to marketing information, Cleveland County Water would provide water to 21 of these properties. A total of 30 properties would likely rely on the First Broad River for water supply. Industrial recruitment efforts are enhanced by several tax credit and incentive programs that are available to industries that locate or expand in Cleveland County. For example, firms such as manufacturing and processing operations, warehousing and distribution plants, and data processing firms that pay at least 110 percent of the average county wage are eligible for tax incentives under the William S. Lee Quality Jobs and Business Expansion Program. 4.3 Land Use and Development Development trends, projected future land use patterns, and local land use policies and regulations were examined to determine the potential effect on future water demand and the distribution of that demand. Draft Purpose and Need Report First Broad River Reservoir Comment [Nii]: Again, how was this information used to estimate (or adjust) future water demand? If was not used, then it is not necessary to provide it. 20 Historically, development patterns in Cleveland County have largely been influenced by transportation corridors. The arrival of the railroad spurred growth in the 1870s and established Shelby as a cotton market and textile manufacturing center. Shelby and Kings Mountain, the largest cities in the county, are located along US 74, an east -west route that traverses North Carolina. Growth in the county continues to be influenced by proximity to 1-85, which traverses the southeastern corner of the county, and by proximity to the Charlotte -Gastonia area. Gardner -Webb University, located in Boiling Springs, also played a role in the growth and development of the southern area of Cleveland County. According to the Cleveland County Planning Director, growth in this southern portion of the county is expected to continue. Cleveland County residents have favored rural or suburban areas to municipalities. The distribution of municipal and rural/suburban population in the county for the period 1950 to 2000 shows that at least 57 percent of the population lived in rural and suburban areas during that time. In 2000, 56,334 of the county's 96,287 residents, or nearly 60 percent, lived in rural and suburban areas. Another trend is the loss of population from the central -city areas in Shelby and Kings Mountain. The Cleveland County Future Land Use Map, adopted as part of the Cleveland County 2005 Land Use Plan, identifies generalized land use patterns through 2015 (see Figure 5). The land use plan map indicates that growth in the county is expected in the central and southern areas with rural residential uses primarily to the north and west. (Rural residential includes residential uses with a 1 -acre minimum lot size and limited commercial uses.) In addition, most of this northern area is in a protected water supply watershed. The predominant land use designation in the central portion of the county (outside municipalities) is residential. Much of this area, which is not in the protected water supply watershed area, is zoned for a one-half acre minimum lot size. Also in this central area, several large employment centers outside municipalities are indicated by light industrial, heavy industrial and commercial designations. These areas are located in proximity to major transportation corridors on the periphery of municipalities. 4.4 Water Demand Projections 4.4.1 Historical Water Demand Available historical water plant records (1999 — 2007) were evaluated to provide a basis for projecting future raw water supply needs. Historical records were provided by residential and non-residential use categories. Non -revenue water usage and Draft Purpose and Need Report First Broad River Reservoir a unaccounted flow records were available for the previous five years (2003 — 2007). Historical records are shown in Tables 14, 15, and 16. The average residential demand was estimated to be 150.6 gpd per metered connection. Using the Census reported average household size for Cleveland County of 2.53 persons, water usage was 59.5 gallons per capita per day (gpcd). Average non-residential demand was estimated to be 465.9 gpd per metered connection. Also, from 1999 to 2007 an average of 9.2 non-residential meters were added to the system each year. Non -revenue water includes water used for system processes such as backwash, line cleaning and flushing, as well as water used for fire protection. From 2003-2007, non - revenue water usage averaged 2.8 percent of the total water plant production. In any water system, a certain amount of water is lost due to leaks and unknown uses. From 2003-2007, unaccountable water loss averaged 17 percent of the total water plant production. 4.4.2 Water Supply Needs Future water demand was projected for Cleveland County Water based on population projections and historical water demand records. Average daily demands for Cleveland County Water are projected to be 6.23 mgd by 2060, while peak daily demands are expected to be 7.78 mgd in 2060, based on the number of existing wells, the projected population growth for Cleveland County, and the district's expansion plans (see Figure 3). In addition to utilizing historical data, several assumptions were made to estimate future water demand. First, it was assumed that the service area population as a percentage of overall county population would remain constant. In Cleveland County, this assumption is supported by past trends regarding the distribution of the county's population in urban, suburban and rural areas. It was also assumed that new residential construction in Cleveland County Water's service area would connect to Cleveland County Water. Projected water demands include an additional 375 connections per year through 2015 due to wells converting. It was assumed that by 2030, all estimated residential wells would be converted to Cleveland County Water. In adjacent counties, it was assumed that Cleveland County Water's customer base would continue to expand to include up to 98 percent of the Rutherford County, Lincoln County and Gaston County expansion areas. In addition, an average of 9.3 Draft Purpose and Need Report First Broad River Reservoir Comment [N12]: Why assume a ratio of 1.25:1 of peak:average demand? What do the actual use patterns show for CCW in the past 5-10 years? If that ratio is different than 1.25:1, wouldn't it be better to use the actual ratio? 22 new non-residential customers will be added to the Cleveland County Water system per year with water usage continuing at rates similar to the previous nine years. Future demand through 2060 for Cleveland County Water, including customers in adjacent counties, is shown in Table 17. 4.4.3 No Build Modeling A No Build scenario was modeled in order to assess the ability of Cleveland County Water's existing run -of -river intake to supply future raw water needs. Specifically, the purpose of the model was to determine the number of days when there is inadequate water in the First Broad River to meet future needs, as described in Section 4.4.2. The model is based on a synthesized period of record from two USGS gaging stations (Casar and Lawndale) from March 1940 to September 2008. Assuming a 70 cfs minimum flow requirement, the future demand of 7.78 mgd would not be met on 9.7 percent of the days (or approximately 2,420 days out of 24,954 days). Of these, as many as 110 days would be consecutive. Water shortages lasting at least 10 consecutive days would occur 4.2 percent of the time. Also, based on historical records, water would not be available on 6.5 percent of the days (or approximately 1,622 days out of 24,954 days). Of these, no water would be available for periods of at least 10 consecutive days for 2 percent of the days., 5. Summary With an estimated available raw water supply at the Cleveland County Water intake of 5.97 mgd, the First Broad River will not consistently meet Cleveland County Water's projected needs. Today Cleveland County Water provides water for approximately 46 percent of Cleveland County's population, as well as for numerous commercial and industrial establishments and adjacent areas of Gaston, Lincoln, and Rutherford counties. With projected population increases, industrial development and the unreliable nature of groundwater in the county, the number of people who depend on Cleveland County Water will certainly increase. The First Broad River does not provide an adequate water supply to meet future demands of Cleveland County Water, given stream flow fluctuations, instream flow requirements and downstream flow needs. In addition, the run -of -river type intake utilized by Cleveland County Water is particularly susceptible to drought conditions such as those experienced in 2002. A more dependable and abundant water supply is needed for Cleveland County. Draft Purpose and Need Report First Broad River Reservoir Comment [N13]: Why is peak 1 demand used, not the average? First, the peak demand is not needed every day of the year. Second, the analysis should assume a reduction in demand when there is a water shortage, due to voluntary, then mandatory, water conservation measures, j What are the model results if the average demand is used? Comment [N14]: Were the only assumptions a min flow of 70 cfs and a demand of 7.78 mgd? Were there other model constraints or operating protocols for low flow periods? J Comment [N15]: It is hard to 1 understand the meaning of the phrases "water shortages", "water would not be available", and "no water would be available". Do they all refer to flows <70 cfs? Again, a realistic operations protocol would allow for withdrawal by reducing the min release to 36.7 cfs. How do the model results differ under that 23 Draft Purpose and Need Report References 6.

At the Cleveland County Water intake on the First Broad River, the estimated available raw water supply under low flow conditions is 5.97 MGD. Historical records from 1940 through 2008 were used to assess the ability of Cleveland County Water's existing run -of -river intake to supply future raw water needs. Depending on the minimum instream flow requirement, the future demand of 7.78 MGD would not be met on 9.7 percent of the days (2,420 out of 24,954 days). Of these, as many as 110 days would be consecutive. Water shortages lasting at least 10 consecutive days would occur 4.2 percent of the time . Demonstration of Need The First Broad River is insufficient to meet projected demands, based on the following conditions: • Fluctuations in the normal stream flow of the First Broad River vary widely and affect water availability at the Cleveland County Water intake on a daily basis. • Cleveland County suffered a severe drought that peaked in 2002. The county is experiencing another drought and is susceptible to future droughts. A long-term solution is needed to ensure adequate drinking water, especially during drought conditions. • Groundwater is not a reliable source of water in the Cleveland County area, as wells either run dry or have low water levels. Water quality is also a concern. It is estimated that approximately 8,000 housing units (approximately 20,240 persons) rely on individual groundwater wells as the sole source of potable water. It is expected that most of these residences will become Cleveland County Water customers through the planning period (2060). • The population of Cleveland County Water's current service area is projected to increase by approximately 6,000 persons by 2060. It is expected that these new residents will be Cleveland County Water customers. • Based on continuing requests for service connections, it is evident that the need for a dependable source of potable water does not stop at the county line. Cleveland County Water already serves approximately 500 customers in Gaston, Lincoln and Rutherford counties. Cleveland County Water plans to expand its service area in areas that can be more easily and economically served by Cleveland County Water rather than existing water systems in these counties. Purpose of the Proposed Action The purpose of the proposed action is to ensure a dependable water supply for Cleveland County Water that meets projected long-term (2060) needs. A "dependable" water supply will provide the district's needs and Comment IN3]: See our comments In the P&N document. If the P&N document Is adjusted, new text will be needed here. maintain required instream flows (assuming water conservation measures are implemented in accordance with an approved drought management plan). Initial Alternatives Considered The regulations developed by the Council on Environmental Quality (CEQ) for implementation of the National Environmental Policy Act (NEPA) process require the development of alternatives for the proposed project and an objective evaluation of "all reasonable alternatives". In order to meet the CEQ regulations the following alternatives have been identified: • No -Action • Implementation of an Aggressive Water Conservation Plan to Reduce Demands • Implementation of the Use of Recycled Treated Wastewater • Increased Utilization of Groundwater Supplies • Increased Withdrawal from the CCW Existing First Broad River Intake • Construction of Additional Finished Water Storage Tanks • Purchase Excess Water Demands from an Existing Public Water Supply System in addition to the continued utilization of the CCW intake. Potential systems to be considered are: ➢ City of Shelby ➢ City of Kings Mountain ➢ Town of Forest City ➢ Broad River Water Authority (BRWA) ➢ City of Hickory • Construction of a New Raw Water Intake on the Broad River • Development of a Reservoir on the First Broad River • Development of a Reservoir on Knob Creek • Construction of a Side Stream (Pumped Storage) Reservoir on Knob Creek with Pumped Storage from the Existing CCW First Broad River intake and Pump Station • Construction of a Side Stream (Pumped Storage) Reservoir on Crooked Run Creek (upper site) with Pumped Storage from the Existing CCW First Broad River intake and Pump Station • Construction of a Side Stream (Pumped Storage) Reservoir on Crooked Run Creek (lower site) with Pumped Storage from the Existing CCW First Broad River intake and Pump Station 2 No -Action Alternative Under the No -Action alternative, CCW would continue to withdraw water from the current raw water intake located at the confluence of the First Broad River and Knob Creek. This alternative would result in no changes to the existing conditions within the project area and water flow fluctuations in the First Broad River would continue to affect the dependability of the river as a water supply for the CCW service area. A review of historical stream flow records and modeling of the river basin as a part of the draft environmental impact statement (DEIS) indicates that the First Broad River has inadequate flow to meet the projected CCW demands as well as in -stream flow requirements imposed by the North Carolina Division of Water Quality and other resource agencies. Approximately 10% of the time the flow in the river is inadequate to { Comment [N2]: see comment on meet both of these demands. page t. Implementation of the "No -Action" alternative would result in periods when CCW would be unable to meet current and projected future water demands, especially during periods of drought or low stream flow. The lack of an adequate water supply has the potential to adversely impact public health and would likely limit population growth and development in Cleveland County, as well as portions of adjacent counties served by CCW. The "No -Action" alternative does not meet the purpose and need for the project given the fact that under current demands the current source is inadequate to supply the required amount of raw water and is certainly inadequate to meet projected future demands. While the "No -Action" alternative would avoid any adverse environmental impacts, it does not meet the requirements of the purpose and need for the project. Requirements of NEPA require that the "No -Action" alternative be carried forward through the completion of the alternatives analysis; therefore this alternative will be carried forward for additional review and consideration as a baseline condition. Implementation of an Aggressive Water Conservation Plan to Reduce Demands The purpose of this alternative would be to implement a more aggressive water conservation plan that would result in a substantial reduction in per capita consumption to a level that would possibly allow CCW to meet future demands without the need for an expansion or development of new water sources. CCW has experienced drought conditions since 2000 and as a result had in place a successful program of water conservation. This program is a volunteer program but management has the option to implement mandatory restrictions in the case of a severe drought conditions or a water emergency. CCW also has in place a "Water Shortage Response Resolution' that was adopted by CCW in February 2003. (See Purpose and Need Section) The resolution stipulates conservation measures for both voluntary and mandatory conservation phases. These measures address indoor residential use, outdoor residential use, and industrial use. The water conservation program has been successful and has resulted in a reduction in per capita demands and the efficient use of the available water supply by the customers of the district. As a part of the DEIS water usage records for CCW were reviewed from 1999 to present. This review indicates that the current residential per capita water consumption over the nine year period is 59.5 gpd. However, this number has decreased to 58.9 gpd/person over the past 5 year period as a result of the water conservation measures. The 59.5 gpd/person average daily flow demand has been used to project future residential water demands. This per capita water consumption is less than more standard accepted per capita recommended demands such as the 400 gpd/connection recommended by the North Carolina Public Water Supply Section in the "Rules Governing Public Water Systems". The current water conservation measures in place have contributed to this lower than normal residential per capita consumption. A review of information provided by the North Carolina Public Water Supply Section comment [N3]: The CCW indicates that other water systems serving basically residential customers in the general vicinity of CCW conservation plan would benefit from Including clearly defined have documented per capita water consumption numbers of 70 to 120 gpd per person. trigger points. Unlike many public water systems the majority of the CCW service area is rural by nature and the use of potable water for irrigation purposes is minimal. Therefore there are no measures that could be implemented to reduce per capita consumption by reducing the use of water for irrigation. As a stand alone alternative a more aggressive water conservation plan would not satisfy the requirements of the purpose and need. However, the continued implementation of a water conservation plan will be a vital part of all other alternatives to be considered and the demand projections being used reflect the effectiveness of the current program. Implementation of the Use of Recycled Treated Wastewater The use of potable water for irrigation purposes by CCW customers is minimal: therefore the use of treated wastewater for reuse purposes including irrigation supply would have minimal impact on the future demands of CCW. A program to utilize treated wastewater effluent is dependent on a customer base that utilizes larger quantities of water for irrigation and other non -potable uses. This is not the case for CCW. In order to adequately utilize treated wastewater will require the upgrade of existing wastewater treatment plants to supply the treated wastewater effluent. CCW does not own or operate an existing wastewater treatment plant. The City of Shelby, City of Kings Mountain and Town of Boiling Springs own wastewater treatment plants that could potentially be utilized and upgraded to produce treated wastewater effluent for reuse purposes. However, it would be more cost effective to identify areas close to these treatment facilities for the reuse of the treated effluent. Any reduction in water demand as a result of the reuse of treated effluent would contribute to the reduction in demand for the City of Shelby, City of Kings Mountain and Town of Boiling Springs, and would not result in a decrease in demands for CCW. The use of treated wastewater effluent to reduce the demand for potable water is not an option for CCW and the program would not satisfy the requirements of the purpose and need and provide for an adequate water supply to meet future demands associated with growth of the system and is therefore will not be carried forward for future consideration. Comment [N4]: What data are available to support this statement. Does nobody in the service area water lawns? Comment [N5]: There Is no mention of reducing the leaks in the system. The P&N document states that unaccounted water is 17% of current demand. This Is equivalent to 0.6 mgd on average. Reducing the 17% figure to 7% by reducing leaks, reduces the unaccounted for value to 0.25 mgd (saving 0.35 mgd). Since the P&N assumes a constant 14% into the future, the savings in year 2060 by reducing leaks to 7% would be worth 0.38 mgd. Comment [N6]: This alternative is missing from the list on page 19. Comment [N7]: See comment above. Increased Utilization of Groundwater Supplies The use of groundwater to meet potable water supply demands in the foothills section of North Carolina has been somewhat limited due to the geology of the area. Granite rock is underlying much of the area and groundwater sources are located within fractures in these rock structures. While smaller communities and residences in Cleveland County with lower water demands have historically been served by groundwater wells, the limited capacity of water from these bedrock fractures limits the ability of larger water users such as CCW to utilize groundwater and depend on it as a source. Groundwater in Cleveland County is obtained by developing wells into fractures in the underlying bedrock. Historically groundwater production wells with capacities of 50 to 150 gpm are typical. There are no well defined aquifers in the Cleveland County area to support the required demands of CCW. To meet the projected demands of CCW well capacity of 7,000 gallons per minute (gpm) would be required. Given the typical well yield the development of an adequate number of wells to meet the projected demands would be very difficult. The North Carolina Division of Environmental Health estimates that it is very unlikely that wells with the pumping capacity needed to meet CCW demands can be found in Cleveland County (Setzer 2007). The recent drought conditions have and continue to impact the capacity of groundwater supplies. Based upon records of new home construction and new meter connections by CCW during the past eight years over 1,000 new customers have connected to the CCW system that were previously served by groundwater supplies. The following table shows the number of new taps, number of new homes and the number of connections attributed to poor groundwater supplies for CCW. TABLE I NEW CONNECTIONS AND GROUINDWATER SUPPLY COMPARISON CCW Year New Construction New CCW Taps Taps Abandoning Use of Groundwater 2000 420 529 109 2001 344 567 223 2002 395 651 256 2003 291 402 111 2004 313 349 36 2005 318 336 18 2006 244 309 65 2007 148 332 184 TOTALS 2,473 3,475 1,002 Water quality may also be a problem. In some areas of the county, existing wells display high concentrations of iron and manganese in the groundwater. Water treatment for these metals is necessary (North Carolina Division of Water Resources 1989). In addition, lithium has been detected in groundwater in the Cherryville and Bessemer City vicinity of Gaston County. (The CCW already has more than 100 customers in Gaston County.) Additional treatment can potentially be a significant expense (Setzer 2007). Due to the shortage of groundwater capacity and water quality concerns, the alternative to utilize groundwater, either from individual wells or large municipal wells, does not meet the project's purpose or therefore will not be carried forward for future consideration. Increased Withdrawal from the CCW Existing First Broad River Intake Withdrawals at the existing CCW intake site are constrained by normal flows of the First Broad River and the required instream flow requirements established by the North Carolina Division of Water Resources. Safe yield for run of the river type raw water intakes is dependent upon the 7Q10 flow of the stream. 7Q10 flow is defined as the average low flow over a 7 consecutive day period that occurs once every 10 years. Water withdrawals of up to 20% of the 7Q 10 flow are typically permitted. The calculated available yield of the First Broad River at the existing CCW intake based upon previously published 7Q10 flows for the stream is 10.0 MGD. However, during the 2002 drought the available supply dropped to less than 4.0 MGD. As a part of the preparation of the DEIS for the proposed First Broad River Reservoir additional modeling of the river has been completed to determine the available water supply. This modeling shows that based upon historical flow records for the First Broad River that the required 7.78 MGD future demand for CCW is not available 10% of the time! The modeling was conducted with an instream flow of 71.6 cfs below the irComment [N8]: see comment on CCW intake. The 71.6 cfs was recently determined as the acceptable required flow by the North Carolina page i, Division of Water Resources (NCDWR) based upon a site-specific study of aquatic habitat and instream flows (see Appendix A). In the absence of some type of raw water storage capacity, this alternative will not provide an adequate supply during drought conditions, is not considered dependable, and does not meet the project's purpose and need. Therefore this alternative will not be carried forward for future consideration. Construction of Additional Finished Water Storage Tanks This alternative would consist of the construction of additional finished water storage tanks to be installed at various locations in the CCW distribution system. During periods of adequate flow in the First Broad River the water treatment plant would be operated at the maximum design capacity of 6.0 MGD. Treated water would then be stored until the time needed for usage. CCW currently has storage tanks with a combined capacity of 5.1 million gallons at various locations within the system. These tanks are located to provide storage needed to maintain adequate system pressures during periods of peak instantaneous demand. The "Rules Governing Public Water Systems" (North Carolina Administrative Code, Title 15A, Department of Environment and Natural Resources, subchapter 18) requires that a minimum of one-half day's supply of finished water be provided (Section .0805). The current storage within the system meets these requirements. Section .1500 of the "Rules Governing Public Water Systems" also address water quality standards and require certain quality parameters as mandated by USEPA and the Safe Drinking Water act as amended. One of these requirements has to do with the formation of various disinfection by-products within the system. The age of the water in the system has a direct impact on these parameters. Implementation of this alternative to build additional finished water storage in the capacities necessary to provide water supply over the periods of low stream flows will have a negative impact on these parameters. The increased water age contributes to increased levels of disinfection by-products and violations of the standards. This alternative will not meet the purpose and need of the project since it will not provide the additional capacity needed to meet the demands of CCW. Therefore this alternative will not be carried forward for future consideration. Purchase Water from other Sources This alternative consists of the purchase of finished water on a wholesale basis from an existing municipal source. Water would be purchased in those amounts necessary to supplement the available supply from the First Broad River. Based upon the reviews of historical stream flow for the First Broad River and available withdrawals by CCW during low flow or drought conditions a minimum of 5.0 MGD of finished water will be needed by CCW to supplement the existing supply during these periods. Each of the proposed I Comment [N9]: The P&N document shows that the highest alternatives for this option must have the capacity to meet this demand. In addition it should be noted that p p ty ! monthly use on record was 4.05 the purchase of finished water from other suppliers will be on an intermittent basis and only utilized during mgd (Sept. 2007). The P&N those periods of low stream flows. document also says that the max daily demand in 2060 is 7.78 mgd. The minimum water Municipal sources which are located in the proximity of CCW that can possibly meet the requirements of production for CCW was 2.98 mgd (Feb. 2006). this alternative are: The difference between MAX • City of Shelby demand more the rangeproduction of 1 mgd in current years and 4.8 mgd in year 2060. This assumes no • City of Kings Mountain conservation by users. Thus, the request for a minimum of 5 mgd (with no mention of when it • Broad River Water Authority (BRWA) would be needed) seems to `overstate the need. • Town of Forest City • City of Hickory To adequately address each of the potential existing finished water systems associated with this alternative additional information is required from the water system as to their ability and willingness to supply water to CCW. CCW in a letter dated December 4, 2208 requested information from each of the water systems to address the technical issues of this option. The information requested is: • Does the water system have adequate excess water supply capacity to meet the projected 5.0 MGD demand during this planning period (2008 — 2060) for CCW during periods of drought? • If so, is there adequate water treatment plant capacity currently in place to supply the CCW demand? If not, are there plans for such capacity, including all associated appurtenances such as raw water pumps, raw water transmission mains, finished water pumps and finished water transmission mains, to be added? • If there is adequate supply and treatment capacity, would the water system be willing to enter into an agreement with CCW in which the water system would agree to sell CCW up to 5.0 MGD during periods of drought? • If the water system can not commit to supplying 5.0 MGD during periods of drought, how much could you commit to supplying? • Please identify the source of the excess capacity the water system would be willing to sell. • Identify those locations where CCW may purchase the supply of finished water. • Identify the hydraulic grade line at the proposed connection points. A copy of the letter may be found in Appendix B. Three of the potential sources either currently utilize or plan to utilize the Broad River as a raw water source. Therefore, a discussion of the Broad River and its impact on water supply in the Cleveland County region is important prior to additional discussion about each of the alternatives. The Broad River forms in the mountains of Western North Carolina in Buncombe, Henderson and Polk counties and flows into Rutherford and Cleveland Counties prior to crossing into South Carolina. The river and its tributaries provide the potable water supply for much of the area. In recent years increased emphasis has been placed on the river for use as a future water supply. The BRWA currently utilizes the river as their source and a section of the river upstream of their intake is protected under the rules for public water supplies and source water protection developed by the Division of Water Quality. In anticipation of the future use of the river both the Town of Forest City and the City of Shelby have successfully permitted the reclassification and protection of others areas of the river for future water supply. The Broad River plays a vital role in the economy of Cleveland County and the surrounding region. The river also provides water supply for power production in the area. Duke Energy has a major power facility located at the Rutherford County/Cleveland County line at Cliffside. This is a fossil fuel fired facility that is currently being expanded and upgraded. Water is withdrawn from the Broad River at this location for use in the production of power. There are also hydro power facilities near Gaffney in South Carolina owned by Duke Energy. In addition there are smaller hydro power facilities in the upper reaches of the Broad River basin at Lake Summit, Lake Adger, and Lake Lure. Duke Energy recently completed a study of the Broad River basin entitled `Broad River Basin Water Supply Study" that evaluated the ability of the river to meet all of the projected water demands including potable water supply, power production, and agricultural needs. The study indicates that the river can meet the projected demands of the region, but with very little margin of error with the assumptions made in the study. USGS maintains a number of stream flow gauging stations in the watershed. One of these stations is located on the Broad River in southern Cleveland County near Boiling Springs (station # 02151500). At this location the Broad River has a drainage area of 875 square miles. USGS has calculated the 7Q10 flow at this location to be 198 MGD. A review of records from the gauging station shows a low flow of 53.6 MGD during the 2002 drought. As previously discussed the NCDWR historically has allowed for the withdrawal of up to 20% of the 7Q10 flow for water supply. Therefore the available supply from the Broad River near the Boiling Springs gauge is 39.6 MGD. Average daily demand for the Cliffside Steam Station was projected to increase from the current of 6.7 MGD to 20.7 MGD in the Duke Energy "Broad River Basin Water Supply Study. These projected demands will have an impact on water supply availability from the Broad River. In addition to the current demands from existing water users on the Broad River other communities have expressed an interest in the development of the river as future water supplies. Polk County has expressed an interest in the construction of a water treatment plant on the Green River. Spartanburg Water System has expressed an interest in development of an intake on the Broad River for the withdrawal of water to supplement their existing supplies from the Pacolet River. Like the Duke Energy demands these potential withdrawals, if developed, will have an impact on the availability of water from the Broad River to meet future water supply demands. The City of Shelby The City of Shelby, like CCW also depends on the First Broad River as the supply for the City's water system. A raw water intake located just north of West Grover Street in the northwestern part of the City supplies water to the city's water treatment plant. The treatment plant has a design capacity of 12.0 MGD and components include three (3) off -stream raw water reservoirs for the storage of water prior to treatment. Current average daily water demands for Shelby are 4.2 MGD. The City of Shelby also provides water on a wholesale basis to the Town of Boiling Springs. The contract amount in 2002 was 1.0 MGD (Shelby Water Supply Plan 2002). Based on the City of Shelby's 2002 Water Supply Plan, average daily water demands for the city's service area are projected to be 8.7 MGD by 2050, including the contract sales of 1.0 MGD. Assuming an average day to peak day multiplier of 1.25, approximately 10.88 MGD would be needed in 2050. The City of Shelby is permitted to withdraw up to 18.0 MGD from the First Broad River raw water intake once the water plant is upgraded and expanded, provided stream flows are adequate to permit the 18.0 MGD withdrawal and also maintain a downstream flow of 25 cfs in the First Broad River. (McGill 2004). To prepare for future drought conditions, the City of Shelby installed a 30 -inch raw water line from the Grover Street Water Plant to the Broad River immediately following the 2002 drought. The project was planned to include a future raw water intake and pump station but these facilities have not been constructed to date. A temporary diesel driven pump has been installed to withdraw water from the Broad River and pump to the Grover Street plant during those periods when low stream flows in the First Broad River dictate the need to utilize this additional source. The Broad River has been reclassified for future use as a raw water source and is currently classified as WS -IV byNCDENR, DWQ. 10 Available water supply from run of river type intakes is typically based upon the 7Q10 flow of the river. Water suppliers are normally allowed to withdraw up to 20% of the 7Q 10 flow without the need for special environmental studies and permitting. Based upon these criteria the estimated available supply at the City of Shelby proposed Broad River intake location is 42 MGD. However, it should be noted that the recent drought conditions experienced in the Cleveland County area have resulted in a decrease in stream flows, including those in the Broad River. A review of flow information for the Broad River during the drought period from 2001 to 2008 shows that stream flows have decreased. In an e-mail dated September 23, 2008 USGS estimates that the 7Q 10 flows for the Broad River watershed may be reduced as much as 28% due to the impact of the recent drought. Should the 7Q10 flows be reduced the available water supply at the proposed City of Shelby intake location would be decreased to 30.8 MGD. CCW has an emergency use agreement and metered connection in place with the City of Shelby. The volume of water currently offered to the CCW is limited and depends on the available water supply. As previously discussed CCW has requested certain information from the City of Shelby as to their ability to supply up to 5.0 MGD of water to CCW. As of this date CCW has not received a response to the letter. Given the current design capacity of the City of Shelby water plant and their projected growth demands the City of Shelby does not have adequate capacity to meet their demands as well as the required future demands of CCW without improvements to their water infrastructure. In order to meet these demands the City of Shelby will be required to expand their water plant. A part of the water plant expansion would include the construction of a raw water intake and pump station on the Broad River to provide adequate raw water capacity for the plant. The purchase of water on a wholesale basis from the City of Shelby appears to have potential as an acceptable alternative that should have additional analysis as an alternative for the CCW project. Therefore this alternative will be carried forward for future consideration. The City of Kings Mountain Moss Lake provides the raw water source for the City of Kings Mountain water plant. The City of Kings Mountain operates an 8.0 MGD water treatment plant adjacent to the lake. The city provides water only within its corporate limits and to its single municipal customer, the Town of Grover. In 2002, an emergency pipeline connection with the City of Shelby was constructed to supplement Shelby's water supply during the drought. In June 26, 2007 CCW entered into an agreement with the City of Kings Mountain to purchase water on an as needed, emergency condition. The agreement stipulates "that if in the event of an emergency situation or need for conservation of the water resources by the City, the city does reserve the right to refuse to supply water to the District, during such emergency or conservation situation. The approximately 1,000 acre Moss Lake reservoir was formed in 1973 by impounding Buffalo Creek and is supplied from the 68 square mile drainage area. Information obtained from the Kings Mountain Water Supply Plan prepared in 2002 and reports prepared by HDR for the Kings Mountain water system indicated that the safe yield of Moss Lake as 23.0 MGD. The HDR report indicates that the Moss Lake reservoir has approximately 12,700 million gallons of storage. The City of Kings Mountain has seen a decrease in average daily water demands over the past several years due to the loss of several major industrial water users. Many of these were within the textile industry sector and their loss has resulted in a significant decrease in average daily water demands. The City of Kings Mountain has initiated preliminary studies as to the feasibility of the construction of a second water supply reservoir on Muddy Creek to supplement the available water supply from Moss Lake. Information provided by HDR indicates that the Muddy Creek reservoir is estimated to provide an additional capacity of 11.1 MGD. The Duke Energy study of the Broad River basin entitled "Broad River Basin Water Supply Study" estimates that the demand of the Kings Mountain system will increase to 7.37 MGD over the study period. Based upon the estimated safe yield of Moss Lake at 23.0 MGD the City of Kings Mountain has adequate capacity to meet both their projected demands and the future demands of CCW. As previously discussed CCW has requested certain information from the City of Kings Mountain as to their ability to supply up to 5.0 MGD of water to CCW. The City of Kings Mountain has responded to the original request and has requested additional information. A copy of the letter may be found in the appendix A. CCW provided a response to the initial City of Kings Mountain letter on December 29, 2008 Given the current design capacity of the City of Kings Mountain water plant and their projected growth demands the City of Kings Mountain does not have adequate capacity to meet their demands as well as the required future demands of CCW without improvements to their water infrastructure. In order to meet these demands the City of Kings Mountain will be required to expand their water plant and portions of the water distribution system. The purchase of water on a wholesale basis from the City of Kings Mountain appears to have potential as an acceptable alternative that should have additional analysis as an alternative for the CCW project. Therefore this alternative will be carried forward for future consideration. Broad River Water Authority In adjacent Rutherford County, the Broad River Water Authority (BRWA) serves the towns of Ruth, Rutherfordton, and Spindale; and some of the rural areas of Rutherford County. The BRWA utilizes the Broad River as its water source with an intake near Rutherfordton, upstream of the confluence of the Green River. BRWA has an 8.0 MGD water treatment plant and has indicated that many of the components are in 12 place for the expansion of the WTP to a capacity of 12.0 MGD. The estimated safe yield at the BRWA intake is 13.1 MGD. CCW has an emergency use agreement and pipeline connection in place with the BRWA. BRWA has made and continues to enter into agreements for the wholesale of water to a number of regional customers. BRWA has an agreement with Grassy Pond Water Corporation in South Carolina for the sale of 0.50 MGD of finished water and have recently entered into an agreement with Inman -Campobello Water District in northern Spartanburg County, South Carolina and Polk County, North Carolina for the sale of finished water. These contracts, as well as the predicted growth of BRWA will approach the available safe yield of the BRWA source during the planning period. As previously discussed CCW has requested certain information from BRWA as to their ability to supply up to 5.0 MGD of water to CCW. In a letter dated December 31, 2008 the Broad River Water Authority (BRWA) indicated that they do not have the capacity required to meet the future demands of CCW. Therefore this alternative will not be carried forward for future consideration. Town of Forest City The Town of Forest City utilizes the Second Broad River as its water source with an intake located north of the town. The Town has an 8.0 MGD water treatment plant with many of the components in place for the expansion of the WTP to a capacity of 12.0 MGD. The town's system includes elevated tanks with a storage capacity of 2.5 MGD. The town's distribution system extends outside the city limits to serve outlying areas and other communities. Forest City sells water, under contract, to the towns of Bostic, Ellenboro, and the Concord Community Water System. CCW does not currently have a connection in place with the Town of Forest City. Current average daily demand in the Forest City service area is approximately 3.0 MGD. During the 2002 drought, the available yield of the Second Broad River at the city's intake was less than 4.0 MGD. In planning for future growth and in anticipation of increased water demands the Town of Forest City has planned to develop the Broad River as an additional water source. The Town owns a site on the Broad River in the southern part of Rutherford County and has plans to construct a new raw water intake and pump station with a capacity of 12.0 MGD to supplement the existing Second Broad River intake and to provide additional raw water capacity for their system. The estimated available supply at the Town of Forest City proposed Broad River intake location is 25.0 MGD based upon the criteria for run of the river type intakes and available withdrawal discussed in the City of Shelby section above. As previously discussed CCW has requested certain information from the Town of Forest City n as to their ability to supply up to 5.0 MGD of water to CCW. 13 As of this date CCW has not received a response to the letter. Major improvements to the Town of Forest City water system infrastructure will be required to allow the Town to meet the projected demands of CCW. These improvements include the expansion of the existing WTP and the construction of a new raw water pump station and transmission line to utilize the Broad River as an additional source of raw water. With these improvements in place the Town of Forest City could have the additional capacity to supply the needs of CCW. However, major improvements to the distribution system would be required to transport the water to the CCW system. In addition water quality could be a concern due to the residence time of the finished water and the impact this residence time could have on water quality. The purchase of water on a wholesale basis from the Town of Forest City appears to have potential as an acceptable alternative provided that the major improvements to their water treatment and distribution system described are made. Therefore this alternative will be carried forward for future consideration. City of Hickory The City of Hickory uses the Catawba River (Lake Hickory) as a raw water supply. The City of Hickory Water Plant has a design capacity of 32.0 MGD, with current demands averaging 12.1 MGD. The City also has current contractual agreements with the City of Conover and Alexander County to provide an additional 6.30 MGD in the future. The city currently has available excess capacity. This alternative utilizes Lake Hickory, part of the Catawba River as the source for raw water. North Carolina regulations require that all flows in excess of 2.0 MGD must be approved by the Environmental Management Commission and may require the development and approval of an environmental assessment prior to approval. To meet the required average daily demand of 5.0 MGD implementation of this alternative would require permission from the North Carolina Environmental Management Commission for an interbasin transfer from the Catawba River basin to the Broad River basin. The Cabarrus County cities of Kannapolis and Concord have an interbasin transfer certificate, approved in January 20007, to transfer 10 MGD from the Catawba River basin and 10 MGD from the Yadkin River basin to the Rocky River basin. The cities requested a transfer of up to 36 MGD from the Catawba River basin; however, only up to 10 MGD was approved. The City of Hickory, as well as a number of towns and counties in the Catawba River basin, passed resolutions in opposition to the transfer. Some of the reasons given for opposing the transfer of water from the Catawba River basin are: • permanent removal of water from the Catawba River will reduce lake levels in all 11 Catawba River lakes including Lake Hickory; • aquatic life would lose water during critical summer low flow conditions; • reduced water levels in the basin would result in additional conservation measures during drought ; • the transfer would result in reduced revenues needed to operate the public water and sewer systems inside the basin; and 14 • Cities and counties within the Catawba River Basin would lose water resources for future economic and population growth. A consortium of Catawba River basin local governments, joined by the Catawba River Foundation, appealed the decision by the North Carolina Environmental Management Commission to grant the interbasin transfer certificate At present. Charlotte -Mecklenburg Utilities also has an interbasin transfer certificate (March 2002) to transfer water (33 MGD) from the Catawba River basin to the Rocky River basin. As previously discussed CCW has requested certain information from the City of Hickory as to their ability to supply up to 5.0 MGD of water to CCW. In a letter dated December 29, 2008 from Kevin B. Greer, P.E., and the City of Hickory has indicated that they do have the excess capacity to provide for the future demands of CCW. However the letter indicates that the purchase of water will be required on a continuous basis. There are also numerous contractual issues that would have to be addresses. Of these the most significant is the approval of an interbasin transfer. Given the opposition expressed by the City of Hickory to the cities of Kannapolis and Concord approved interbasin transfer and opposition from other groups in the Catawba River basin it appears that an approval to obtain the required 5.0 MGD of water from the City of Hickory would be difficult. In addition CCW does not need to purchase water on a daily basis as required by the City of Hickory. Based upon these factors this alternative will not be carried forward for future consideration. Construction of a New Raw Water Intake on the Broad River This alternative would consist of the construction of a new run -of -river type intake on the Broad River and the utilization of the Broad River for a raw water supply by CCW to supplement the existing First Broad River source. As previously discussed both the City of Shelby and the Town of Forest City have documented plans for the future use of the Broad River as an alternative water source. The safe yield of the Broad River is estimated to be between 25.0 MGD and 42.0 MGD depending upon the proposed intake location and based upon a withdrawal of 20 percent of documented 7Q 10 low flow. In adjacent Rutherford County, the Broad River is the raw water source for the BRWA and will be utilized by the Town of Forest City in the near future. The Second Broad River, a Broad River tributary is the raw water source for Forest City, Bostic, and Ellenboro. The City of Shelby recently constructed a temporary emergency intake on the Broad River for use in emergencies and a portion of the river and watershed were reclassified to WS IV for use as a water supply. Several other municipalities have expressed interest in future utilization of the Broad River for water supply, including Spartanburg Water System in South Carolina. Polk County, in the upper reaches of the Broad River basin has expressed a desire to construct a new raw water intake, pump station and water treatment plant on the Green River, a major tributary of the Broad 15 River. In consideration of the available safe yield, other demands for water from the river will impact the amount of water available for CCW. The Broad River has adequate supply to meet the projected demands of CCW and to supplement the current First Broad River source. The absence of raw water storage capability however will make this option, susceptible to drought conditions, but the river appears to have adequate capacity to meet the projected CCW demands. Therefore this alternative will be carried forward for future consideration. Reservoir on First Broad River This alternative would consist of the construction of a dam on the First Broad River, immediately upstream of the existing CCW raw water intake and treatment plant. The initial proposed alternative would impound § areas below 860 -feet msl, providing an estimated safe yield ofJ MGD (The safe yield is based on the release of 71.6 cfs for in -stream flow needs.) An earthen dam would be constructed across the First Broad River upstream of the existing CCW raw water intake. The impoundment would extend west of NC 10 and have a surface area at full pool of approximately 1,300 acres. The total drainage area upstream of the dam location is approximately 146 square miles. Different scenarios of this option will also be evaluated with pool elevations at 850 and 840. Each of these scenarios will result in smaller impoundments which will also decrease the safe yield of the reservoir. This alternative meets all of the requirements of the purpose and need of the project and will provided the required raw water needed for future potable water demands. This alternative also ensures a more reliable source for the City of Shelby from the First Broad River and will enhance the aquatic conditions in the First Broad River due to increased stream flows as a result of controlled releases from the new reservoir. Therefore this alternative will be carried forward for future consideration. Development of a Reservoir on Knob Creek This alternative would consist of the construction of a dam on Knob Creek and would impound areas below 860 -feet msl. The proposed reservoir would have a total drainage area of approximately 35 square miles. Based upon modeling results the estimated safe yield of this alternative would be A; MGD. (The safe yield is based on the release of 11 cfs. The 11 cfs minimum release was calculated based upon the minimum release for the first Broad River of 71.6 cfs as determined by NCDWR and adjusted to the smaller drainage basin.) For this alternative water would be released from the dam to the existing raw water pump station at which point the water will be picked up and pumped to the water plant. To impound Knob Creek, an earthen dam would be constructed east of the CCW water treatment plant and Lawndale-Cesar Road. See Figure I for a map of the lake. The dam would create a reservoir on Knob Creek with a surface area of approximately 498 acres. With buffers, the area required for this alternative is approximately 650 acres. 16 Comment [N10]: This document should list all assumptions and model operations protocols used to calculate the safe yield estimates for all of the reservoir alternatives. For example: 1. min flow of X 2. min flow does (or does not) change with season or inflow 3. demand Is reduced (or not) under mandatory conservation 4. pump size of X mgd 5. etc. Were the results of the instream flow study done by NCDWR used in the assumptions? If not, these safe yield estimates might be off and none of the alternatives should be discarded until new model runs are performed equivalent to ALT 2 and ALT 3A. Comment [N11]: Provide updated safe yield estimates for all reservoir alternatives. Formatted: Formatted: Highlight This alternative will meet the requirement for projected demands for CCW, but with very little margin for error in demand projections and other assumptions as to water demands for minimum release and evaporation. Therefore this alternative will be carried forward for future consideration. Construction of a Side Stream (Pumped Storage) Reservoir on Knob Creek with Pumped Storage from the Existing CCW First Broad River intake and Pump Station This alternative is identical to the alternative previously discussed for Knob Creek with the exception that this alternative will have a much larger safe yield as raw water from the First Broad River will be pumped Comment [N12]: Provide a from the existing CCW raw water intake at the confluence of the First Broad River and Knob Creek. The number. pumped storage option will increase the safe yield of this alternative to 15.0 MGD. This alternative will meet the requirement for projected demands for CCW as described in the purpose and need statement. However as this alternative will utilize the pumped storage option stream flows below the existing intake will be decreased to those minimum amounts required by the Division of Water Resources. This alternative will be carried forward for future consideration. Construction of a Side Stream (Pumped Storage) Reservoir on Crooked Run Creek (upper site) with Pumped Storage from the Existing CCW First Broad River intake and Pump Station This alternative would consist of the construction of an "off -stream reservoir" on Crooked Run Creek to provide for the storage of raw water. Two locations have been identified as potential reservoir sites. The upper impoundment would be located just north of Kistler Road (SR 1514) and extend upstream in a northwest direction to Walker Road (SR 1517). This option would form a reservoir with a surface area of approximately 650 acres and has a drainage area of 5.7 square miles. The proposed reservoir will utilize the pumped storage option and would be maintained at full pool elevation during periods of normal to high flows in the First Broad River by pumping water from the existing CCW raw water intake and pump station located at the confluence of the First Broad River and Knob Creek to the Crooked Run Creek reservoir. 'Be existing pump station will be upgraded to increase the pumping capacity to a pump capacity of 15 MGD. During periods of low flow in the First Broad River, raw water would be withdrawn from the "off -stream reservoir" for use in the CCW water treatment plant to supplement flows from the First Broad River. A new raw waterline would convey water from the reservoir to the existing water treatment plant. 'Be upper site and the resulting 650 -acre reservoir would have a safe yield of; S MGD. See Figure 11 for { Formatted: Highlight a map of the reservoir. This alternative requires the daily withdrawal of water from the First Broad River to the reservoir from the existing CCW raw water intake. The daily flow will be required to maintain water quality in the reservoirs due to the small drainage areas and the resulting normal inflow. 17 This alternative meets the requirement for projected demands for CCW as described in the purpose and need Deleted: statement. This alternative will be carried forward for future consideration. Construction of a Side Stream (Pumped Storage) Reservoir on Crooked Run Creek (lower site) with Pumped Storage from the Existing CCW First Broad River intake and Pump Station This alternative would consist of the construction of an "off -stream reservoir" on Crooked Run Creek to provide for the storage of raw water. This scenario has a reservoir location located further downstream on Crooked Run Creek closer to the First Broad River. This option would form a reservoir with a surface area of approximately 220 acres and has a drainage area of 6.9 square miles. The proposed reservoir will utilize the pumped storage option and would be maintained at full pool elevation during periods of normal to high flows in the First Broad River by pumping water from the existing CCW raw water intake and pump station located at the confluence of the First Broad River and Knob Creek to the Crooked Run Creek reservoir. The existing pump station will be upgraded to increase the pumping capacity to a pump capacity of 15 MGD. During periods of low flow in the First Broad River, raw water would be withdrawn from the "off -stream reservoir" for use in the CCW water treatment plant to supplement flows from the First Broad River. A new raw waterline would convey water from the reservoir to the existing water treatment plant. The lower site and the resulting 220 -acre reservoir would have a safe yield of,9,0 MGD. See Figure III for a Formatted Highlight map of the lake. This alternative requires the daily withdrawal of water from the First Broad River to the reservoir from the existing CCW raw water intake. The daily flow will be required to maintain water quality in the reservoirs due to the small drainage areas and the resulting normal inflow. This alternative meets the requirement for projected demands for CCW as described in the purpose and need Deleted: statement. This alternative will be carried forward for future consideration. 18 Alternatives for Further Consideration After consideration of initial alternatives the following selected alternatives are recommended to be carried forward for future evaluation:': • No action • Purchase Excess Water Demands for an Existing Public Water Supply System. Potential systems to be considered are: ➢ City of Shelby ➢ City of Kings Mountain ➢ Town of Forest City • Construction of a New Raw Water Intake on the Broad River • Development of a Reservoir on the First Broad River • Development of a Reservoir on Knob Creek • Construction of a Side Stream (Pumped Storage) Reservoir on Knob Creek with Pumped Storage from the Existing CCW First Broad River intake and Pump Station • Construction of a Side Stream (Pumped Storage) Reservoir on Crooked Run Creek (upper site) with Pumped Storage from the Existing CCW First Broad River intake and Pump Station • Construction of a Side Stream (Pumped Storage) Reservoir on Crooked Run Creek (lower site) with Pumped Storage from the Existing CCW First Broad River intake and Pump Station 19 �- -- - --- --------------- Comment _ -Comment [N131: The alternatives list should repeat the statement from page 4 that water conservation and leak detection will be used in conjunction with each alternative.
