These customers are located in four counties and two states: Cleveland, Rutherford, Gaston, and Lincoln County in North Carolina and Cherokee County in South Carolina. CCSD has only one water treatment plant and one water intake on the First Broad River near its confluence with Knob Creek. CCSD has two emergency connections with the City of Shelby water distribution system and Broad River Water Authority. The purpose of the proposed project is two-fold. First based on the current rate of growth, the CCSD has projected that the needs of the County will double by 2050. The current sources of water and treatment facilities in the County cannot meet this demand. Second, the growth of the entire region is such that demands both upstream and downstream by other counties and states are also increasing. In the interest of providing a reliable safe water source and preventing water rights conflicts, it is necessary to begin to establish a regional approach to solving the future water needs and look at the riverbasin as a whole. The need for this type of planning on both the long and short term was dramatically re- enforced during the recent drought. The First Broad River has an average flow of 45 MGD under normal conditions, but during the drought of 1999-2002, the river dropped to 3 MGD. Similar situations occurred throughout the adjacent areas and many water districts faced extreme short falls. The proposed project looks at the future demand, the downstream and upstream needs of the communities on the First Broad River and its tributaries, the minimum flows needed to sustain the river, and the possibility of future drought. With this in mind, the project is designed to provide more than just the immediate and future needs of the CCSD. 2.0 Alternatives Analysis 2.1 AVOIDANCE ALTERNATIVES 2.1.1 No Action The estimated safe yield under non-drought conditions of the Cleveland County Sanitary District water source is 10.0 MGD. The water treatment plant has a design capacity of six (6) million gallons per day (MGD). The current average daily production rate at the treatment plant is 3.84 MGD. Water demand projections for the County have shown that the plant and withdrawal volume and permitted expansions will be adequate until sometime in the 2030's (2040 will be at 10.15 MGD demand). During the drought period of 1999-2002, the summer water supply became limited in the early years and was inadequate during the summer of 2002 for all water supply utilities in the Cleveland County area. In 1992, North Carolina indicated that the safe yield of the river must be reduced to 5.0 MGD at the current intake when river flows are less than 70 cfs. The First Broad River and most other water supplies in the region were unable to provide a safe water yield with the exception of the Catawba River. The Catawba River was able to meet the water supply demands only because the large number of reservoirs on the system provided storage for the water withdrawals. These reservoirs included Lake James, Lake Rhodhiss, Lake Hickory, Lookout Shoals Lake, Lake Norman, Mountain Island Reservoir, and Lake Wylie. The Catawba River water connections will be restricted as a water source due to downstream needs in the Catawba River Watershed and the limitations of interbasin transfer. The No Action Alternative would not impact any additional streams or wetlands; would not impact any land or buildings; would provide adequate water supply until the 2030's; and would not impact any rare species during this period. The No Action Alternative would be a short-term measure as planning and design for expansion would be needed by the 2020's based on predicted water demand (20 year postponement). By the 2020's, costs of land acquisition and construction will be higher, no matter which alternative is chosen. The No Action Alternative also does not address the capacity of the Broad River in drought/low flow conditions, which have caused problems in the past and are likely to be experienced in the future. The selection of this alternative will result in limiting growth within Cleveland County, the inability to supply clean water to those citizens located within the CCSD service area, and lack of service to other municipalities in the region. Limiting growth will result in decreased employment opportunities for the residents of the County and will require increased dependence on already taxed ground water supplies to meet the demands for future residential development. The lack of an additional water supply and the limited growth could result in the degradation of the quality of life for the current county residents due to limited employment possibilities. 2.1.2 Water Conservation Cleveland County Sanitary District has a program of voluntary water conservation at all times and a mandatory program of water conservation during periods of drought. The program restricts the watering of lawns and gardens in the District. This program was used extensively in the summers of 1999-2002 during the drought period. The District experienced a decrease of water usage during this period and usage remained depressed after the mandatory conservation was removed. Public acceptance of this alternative is minimal except during periods of drought. Mandatory conservation levels required enforcement efforts. The conservation program did not lower the water usage to the extent where no expansion of the water supply would be needed, especially during drought conditions. Outside District sources of water supply had to be found and used during the summer of 2002 even with the mandatory conservation program in place. CCSD has used incentives for reducing flows, including low flow plumbing (toilets) and education on repairing water leaks within the residence. There has been little reduction in demand. CCSD has no large industry in its service area at this time, only residential and commercial; therefore there are no requirements for industrial recycle or reuse. Although water conservation would limit environmental impact, the implementation of a water conservation program will not negate the demand for an additional water supply in the future. An aggressive water conservation plan will only extend the time frame when an additional supply is required. Typically, a water conservation plan for a system with predominately residential customers like CCSD will result in a 10% or less decrease in water usage. No other measures were available to increase the water conservation program. Based on the conditions experienced during the drought of the 1999-2002, water conservation measures may meet a portion of the water demand needs in the future, but will not be adequate for all of the needs. Community interest or commitment to the program is acceptable for short terms and for well-publicized environmental limitations on the water supply. The CCSD will continue to promote the use of the conservation program but predicts it will address only a small percentage of the future demand. 2.1.3 Recycle and Reuse of Wastewater In Cleveland County Sanitary District, there are no large users of water and there is no CCSD wastewater plant. The producers of treated wastewater are outside of the District (Shelby WWTP). This limits the ability of CCSD to implement a program of recycle and reuse of wastewater on a large scale. This alternative will not result in a decrease in demand for the CCSD. Recycling efforts are encouraged by both County and State in such commercial activities as cooling water systems, car washes, and other heavy users of water. CCSD has only small, low volume customers for water, which do not lend themselves to recycle and reuse programs. CCSD proposed the recycling of water used to backwash the water treatment filters by returning it to the pond for reuse. The state would not approve this measure due to health concerns. 2.1.4 Groundwater Groundwater sources for potable water in the Piedmont of North Carolina ire not lazge and are not consistent in volume. There are no aquifers of large enough capacity to serve large municipal systems in the Cleveland County area. As shown by studies in the NC Piedmont area for the Randleman Dam, large numbers of wells over a lazge area are required to supply an equivalent amount of water to a reservoir. Draw down of the water table impacts local surface water features (wetlands and streams), impacts neighboring well yields, and demands the most water at the driest season, further dropping the water table and increasing the associated impacts. Smaller communities and individual residences and businesses are served by well water in the azea. The largest community in the area served by ground water wells is Falston, NC, which draws approximately 150,000 gpd from multiple groundwater wells in the azea. This was supplemented regularly with up to 30,000 gpd for maximum demand periods from the Cleveland County Sanitary District during the 1992-1997 period. This alternative is not a feasible or reliable alternative water supply source in the long term for CCSD for the amount of safe water yield that is required. 2.1.5 Purchase of Water from an existing or proposed Regional Source City of Sher The City of Shelby has a 12.0 MGD water treatment plant that utilizes the First Broad River as its water source. Cleveland County Sanitary District has an emergency use agreement and pipeline connection in place with the City of Shelby. Up to 321,000 gpd for 10 days for emergency use can be supplied by the Shelby system to the CCSD. Shelby has limited the volume available to CCSD, and the pipeline connection is also constrained by the 12" pipe connection between the two systems. During the drought, Shelby Utilities had to construct an emergency intake line to the Big Broad River to supplement their water intake on the First Broad River. Shelby also constructed an emergency pipeline connection with Kings Mountain in 2002. Long term availability of the Shelby connection for enough water volume for the CCSD is questionable and Shelby has indicated no desire to expand the amount available to CCSD. Kin s Mountain The Town of Kings Mountain owns Moss Lake, which provides potable water for the Town. Current average daily demand is 7.0 MGD. The published safe yield of Moss Lake is 20 MGD. However, the past drought conditions have resulted in a drop of lake level to unacceptable levels. These low levels and the relative small drainage area for the lake have resulted in the North Carolina Public Water Supply Section and others questioning the published safe yield of the reservoir. There currently is no direct pipeline connection between the Town and CCSD. Kings Mountain did construct an emergency pipeline connection with the City of Shelby in 2002 to supplement the City's water supply during the drought. Growth is expected to occur in the Kings Mountain service area at the same rate as the CCSD. The predicted demand in 2010 will be 7.9 MGD. That leaves approximately 7.0 MGD that may be available for sale to other systems, if the distribution system is adequate and if the Town of Kings Mountain allows the sale. The City of Kings Mountain has indicated that their supply is for Kings Mountain customers only and has not expressed interest in providing water to the community outside of their jurisdiction. City of Hickory The City of Hickory Water System may provide a possible source of water from the Catawba River. The City of Hickory operates a 30.0 MGD water plant that utilizes the Catawba River (Lake Hickory) as a raw water supply. Based upon current demands, the City of Hickory has the ability to supply up to 8.0 MGD for future demands. Future additional water supply demands for Cleveland County are estimated to be 34.0 MGD for those suppliers utilizing the First Broad River. Available supply from the river during the 2002 drought was less than 5.3 MGD. Therefore, the purchase of up to 28.7 MGD of finished water would be required from the City of Hickory in the future to meet the projected water demands for Cleveland County. The City of Hickory does not currently have available excess capacity to provide this demand. However, it may be feasible to expand the existing water plant to meet some of these proposed demands. Improvements to both the City of Hickory and the Catawba County water distribution systems will be required to transport the quantity of water required to meet future demands to the Cleveland County Sanitary District system. Preliminary project cost estimates for improvements to deliver 16.0 MGD as an initial phase are $14,164,000 (Table 1). This cost does not include any cost associated with the upgrade or expansion of the City of Hickory water plant. In addition to the cost for the major improvements to the existing water distribution systems the City of Hickory, Catawba County and the CCSD would have to request special permission from the North Carolina Environmental Management Commission to transfer the requested amount of flow from the Catawba River basin to the Broad River basin under the North Carolina inter-basin transfer rules. There is an interbasin transfer in place already where an average of 1.47 MGD withdrawn from the Kings Mountain system is discharged into the Catawba River (LWSP, 1997 data). During the drought years of 2001 and 2002, municipalities on the Catawba River in NC and SC expressed concern that the Catawba River would not have enough flow to serve all water supply demands and the instream flow requirements. This area is experiencing a high rate of growth, especially between Statesville and Charlotte, and municipalities will not be supportive of water supply interbasin transfers. Other Regional Sources No proposed regional source exists and no combination of existing water authorities is proposed for the area. In the region, reliability of all the other water sources except the Catawba River were shown to be inadequate during the recent drought. All water supply authorities in the region required conservation measures and found additional water supply sources to supplement their existing sources in the summer of 2002. Minimum instream flows in the First Broad River and other rivers were not achieved during this period. All of the major rivers in the region are being considered for additional water sources (Big Broad River and Green River for Spartanburg; Big Broad River and Kings MountainlMoss Lake emergency connection for Shelby; Big Broad River for Forest City and other water systems in SC). This Alternative can address some of the future water needs for the CCSD, especially in an emergency situation. This Alternative is not a reliable source of water for future needs due to the costs and the needs of the other individual regional providers who are under pressure to ensure an adequate and safe water yield for their consumers. 2.1.6 Request Increase Withdrawal at Existing Intake Site There is no additional safe yield volume available at the existing intake. CCSD's current river intake is located on the First Broad .River near Knob Creek. Normal flows of the First Broad River average 45 MGD (70 cfs) and NPDES discharge permits are based on this flow. With CCSD eventually withdrawing the maximum permitted amount of 10 MGD and Shelby withdrawing the maximum 16 MGD that the plant can handle, the river is left with 19 MGD. A minimum of 16.2 MGD (25 cfs) below the Shelby WTP intake is required to maintain stream habitat downstream, so there is less than 3 MGD available volume to withdraw. At this maximum permit level, this withdrawal has impacts on all NPDES permit dischargers downstream when the normal water flow drops below 45 MGD. Specifically, the permitees will be required to remove more pollutants before discharging, increasing the cost of treatment of the wastewater. These costs would have to be absorbed through WWTP customers, creating a cost to the general community not served by CCSD. The current plant facility can process 6 MGD with plans in place to expand the facility to 10 MGD in the near future, delaying the need for expansion or new sources for a period of time. This will maximize the withdrawal at the intake as much as possible, delaying the time when additional sources will be necessary. However, this will not address future demands after 2030. Also, the safe yield at the CCSD intake has been shown to be as low as 3.0 MGD (4.6 cfs) during the 2002 drought. CCSD is addressing as much of the water needs of the county through this option as possible, but it will only address a portion of the needs in the future and not adequately or reliably during times of drought. 2.1.7 Upland Constructed Flow Augmentation Reservoir This alternative is more commonly used in the western states where snow melt provides a source of water volume during the spring months that is used to supply safe water yield during the summer dry months. Flow augmentation reservoirs could be constructed off line as storage reservoirs, filled either by gravity flow or pump storage. Either option would provide the CCSD with additional water. Upstream sources in the headwaters are limited in appropriate reservoir sites and are located in areas with High Water Quality streams. The reliability of the source and the amount of water available is of concern in the headwater locations. Further downstream, this alternative would be feasible except in times of drought. An additional considerations are the size of a flow augmentation reservoir needed to help provide 34 MGD, available land, and placement. This is not considered a reliable alternative source for CCSD. 2.2 SURFACE WATER SUPPLY ALTERNATIVES 2.2.1 Traditional Reservoir (no .pumped storagel A traditional water supply reservoir was considered for the First Broad River. Other rivers in the region were rejected because of size constraints, cost estimates, existing water demands on the system (Big Broad River), distance to the CCSD Water Treatment Facility, or location within other regional utility service areas. First Broad River Reservoir The recommended reservoir would consist of an impoundment of the river that would provide for the in-stream flow needs for those areas located below the proposed reservoir. The proposed project will provide a safe, reliable supply of high quality raw water to meet the long-term needs of Cleveland County. The First Broad River watershed is currently classified for potable water supply and has a classification of WS-III upstream of the CCSD intake. This classification will protect and provide a high quality water supply, with adequate capacity to meet future demands for the residents of Cleveland County. The preliminary investigations of the proposed reservoir sites were performed taking into account yearly variability of streamflow, regional effects of evaporation, potential for sedimentation, and minimum downstream release required for the First Broad River. Preliminary studies on several sites were performed to consider the volume, surface area, shoreline, safe yield and number of roads, bridges, cemeteries and schools that would be affected for each site (McGill, 1997, Feasibility Study First Broad River Reservoir). Two sites on the First Broad River were considered for in depth evaluation for potential reservoir sites. One site was also evaluated at three different pool elevations. The Feasibility Study eliminated one site and one elevation due to cost considerations. A second elevation (880 msl) was evaluated for cost/benefit ratio of safe water yield and cost but is not the preferred alternative. The higher elevation would impound more water but would have a wider environmental impact and impact more properties than the lower elevation. The additional yield from the 880 msl elevation was not considered feasible due to those impacts. The proposed reservoir will be formed by the construction of a dam approximately 3,500 feet up-stream of the Cleveland County Sanitary District's current raw water intake (Figure 1). The dam will create a reservoir with a surface area of approximately 2245 acres and will impound those areas below elevation 860 feet msl. The reservoir will have a drainage area of approximately 146 square miles and will impound a usable volume of raw water of 5.4 billion gallons. Depending upon the release rate required to meet down- stream, in-stream flow requirements (estimated at 16.2 MGD or 25 cfs per Shelby WTP permit), the safe yield of the proposed reservoir would be 34.0 MGD. In addition to providing an estimated safe yield of 34 MGD for the CCSD, the proposed reservoir also provides up to 18.0 MGD of release for withdrawal and treatment by the City of Shelby at their raw water intake. This reservoir would meet the needs of the CCSD to provide a reliable water source. Positive impacts resulting from the construction of a reservoir include creation of waterfowl habitat, lake habitat and fishery, increased riparian buffer, water source and foraging opportunities for terrestrial species, more linear shoreline footage, and restricted access of cattle to streams and river which would include health benefits and sedimentation alleviation. The reservoir would also increase recreational opportunities for the public and property values. Negative impacts of the reservoir include a loss of 24 miles of river and stream habitat, 1500 acres of forested or agricultural land, and 0.06 acres of wetlands. Other negative impacts include the effect on the current population of Hexastydis naniflora which will have to be rescued/relocated, one bridge replacement, loss of one connector road, and additional law enforcement activities required for the reservoir. Mitigation for the takings will include a variety of activities. The minimum amount of buffer around the reservoir will be increased to provide a forested corridor of at least 100' around the entire lake with larger tracts of adjacent land as available. Additional conservation easements on the tributaries and headwaters around the lake and in other areas of the County will be pursued to provide vegetated buffers along all water courses. Erosion and sedimentation control as well as stream restoration will be funded through the NRCS and other appropriate agencies. Recreational projects such as development of a public boat launch area with parking, public bank fishing access, and picnic facilities will be developed in consultation with the Wildlife Resources Commission and Parks & Recreation. Construction of the reservoir will provide for the long-term demands for raw water within the county for the next 50 years. In addition the impoundment will permit the regulation of downstream flows to provide for the protection of existing aquatic habitats and maintain the in-stream flows necessary for the discharge of treated wastewater from those facilities located downstream. This is an important consideration for the First Broad River considering that the instream flows could not be maintained in 2002 due to the drought conditions. The various options for surface water supply alternatives have one common component. The water will have to be obtained from the First Broad River drainage basin. The Broad and Catawba Rivers have numerous demands for water supply from other municipalities both in state and out of state. The capacity to supply all demands is not present. Therefore, the alternatives that are under consideration involve the same water source. If the water is from one on-line reservoir, a storage facility, on-line reservoirs in the tributaries, or multiple storage reservoirs, the water comes from the same system. Instream flow needs, 7Q 10, and stream flow protection can only be achieved by construction of one or more reservoirs with sufficient capacity to augment flow during drought or even normal low flow periods. 2.2.2 Construction of Several Reservoirs Big Broad River Reservoir(sl Because of the constraints noted under Traditional Reservoir and River Intake System sections, the Big Broad River has no excess capacity and will be used by several other utilities. These Water Systems have not expressed interest in a regional impoundment on the Big Broad River. A reservoir on the Big Broad River is not under consideration by the CCSD because of these reasons. First Broad River Reservoirs All other streams in the CCSD are in the First Broad River watershed and as such, would not add to the total volume of water flow or safe water yield for the District in conjunction with the Preferred Alternative. Multiple reservoirs in the First Broad River Watershed would only be a replacement option to the one main dam. The construction of several reservoirs would spread out the impacts of impoundments so that each impoundment would be a smaller impact on the environment. However, in order to achieve the same amount of safe water yield, it would be necessary to build several reservoirs. These reservoirs would be spread outside of the area where one reservoir would impact, increase the communities involved, impact more landowners, and shift the obstructions to aquatic life to the smaller streams. There is a potential for more wetland impacts on the smaller stream systems than there is on the main river system. There would be an increase in cost for maintenance of the dams, piping and pumping the water from the individual reservoirs to the water treatment plant. The CCSD as well as each of its customers could construct their own reservoirs. This alternative would likely result in smaller environmental impacts per reservoir; however, overall it is likely that the cumulative impacts of all the reservoirs may be greater. CCSD customers are mainly residential or small commercial facilities. Building reservoirs for each customer in this case is not practical. Building small reservoirs in each community is possible. This would increase the cost because of the number of construction sites and the additional water treatment facilities. CCSD service area does not lend itself to centralized smaller water treatment plants. This option would not address the problems of minimum flow in the First Broad River during normal low flow or drought. It is predicted that the diminution of tributary flows would exacerbate the instream flow problems in the First Broad River. Also, there is a consideration of the impacts due to drying up a small reservoir seasonally and the increased turbidity as water levels fall requiring additional treatment at the water plant. 2.2.3 River or Stream Intake System no storage reservoir First Broad River The current CCSD uses a river intake system on the largest river system in their service area. As noted under #6 in Avoidance Alternatives, between CCSD and the City of Shelby, the First Broad River will have no excess capacity in the future. The river has already experienced a lack of safe water yield during periods of drought (1999-2002). Big) Broad River The only other river of appropriate size in the region that would be cost effective for municipal water intakes is the (Big) Broad River. This would consist of the construction of a new run of the river type intake on the Big Broad River and the utilization of the river for a raw water supply in addition to the First Broad River. The Big Broad River is not currently classified for use as a water source. Prior to the utilization the watershed will require classification for use as a water supply, a process that can take up to three (3) years. Water quality of the Big Broad River is certainly not equal to that of the First Broad River. A number of wastewater treatment facilities utilize the river for the disposal of their effluent upstream of the proposed intake location. In addition, non-point source pollution from stormwater runoff is greater than that of the First Broad River watershed as a result of the type of development within the watershed. Several problems are a concern with the long-term dependence of the Big Broad River. The first and most important will be the available safe yield of the river. Historically water suppliers have been limited to withdraw no more than 20% of the 7Q 10 flow of the river for water supply without special provisions. Flows in the Big Broad River were measured at 40 MGD during the summer of 2002, near the location of the Shelby emergency intake. Assuming the implementation of the 20% rule and to provide for the in-stream flow demands of current users of the Big Broad River, the maximum safe yield is estimated to be 8.0 MGD. The City of Shelby needs a projected 12.47 MGD for future use. During 2002, only 1.5 MGD was available from the First Broad River at the City's intake. Therefore, the development of the Big Broad River as the future water supply will not provide sufficient water to meet the City's projected demands nor be available to address the needs of CCSD. It should be noted that the 1.50 MGD of available supply estimated from the First Broad River in 2002 did not include flow releases for in-stream aquatic habitat demands as recommended by the division of Water Resources. It is also unclear at this time the impact other additional demands for water from the Big Broad River will have on the amount of water available for the City of Shelby and Cleveland County. The Town of Forest City has indicated the desire to develop an intake on the river upstream of Cleveland County and withdraw up to 12.0 MGD. They have implemented the process of reclassification for the watershed upstream of their intake location. The Broad River Water Authority, City of Gaffney and the City of Spartanburg, South Carolina have also expressed interest in future utilization of the river for water supply. With the other regional demands on the Big Broad River, this alternative is not considered a viable option for the CCSD. 2.2.4 River or Stream Intake with One Storage Reservoir This alternative would consist of the construction of a reservoir located near the existing Cleveland County Sanitary Water Treatment plant. The reservoir would not be a run of river type reservoir impounding the First Broad River. However, due to topography of Cleveland County, this "off-stream reservoir" would impound some existing stream. Sufficient land is not available to provide an "off-stream reservoir" to provide the 34 MGD safe yield of the larger run of the river reservoir. An area of approximately 850 acres is required to construct an "off-stream reservoir" of sufficient usable capacity to supply this type of safe yield. The location of this size of upland tract would be difficult to find which would minimize the impact to streams, existing farm land, homes, and roadways. Therefore, a scenario was developed where an upland "off-stream reservoir" could be constructed to provide a minimum safe yield of 11.0 MGD for a period of three (3) months, based upon low flows in the First Broad River. A site was located just north of the existing plant that could possibly serve the purpose of this alternative. A reservoir with a surface area of 700 acres could be developed in this location. The reservoir would be maintained at full pool elevation during periods of normal to high flows by pumping water from the First Broad River to the reservoir. This will require that the existing CCSD raw water pump station be upgraded to include larger pumping units. During periods of low flow in the First Broad River, raw water would flow from the "off- stream reservoir" through a 36" raw water line to the water treatment plant. The reservoir would be designed to have sufficient holding capacity to provide a safe yield for the water treatment plant of 11.0 MGD. Available water from the First Broad River would be withdrawn from the river and pumped to the reservoir for storage prior to usage. The actual amount of water available for withdrawal from the First Broad River during low flow periods must be determined by joint agreement between the North Carolina Division of Water Resources, Division of Water Quality, Fish and Wildlife Service, and other regulatory agencies. However, based upon the most recent drought period, there could be times when no withdrawal would be available form the river basin. This reservoir would impact approximately 5 miles of Crooked Run Creek or its tributaries. Construction will also impact approximately one half mile of existing roadway which will require improvements to raise the level of the roadway to prevent flooding. The reservoir would impound Crooked Run Creek and have supplemental water pumped from the First Broad River. This alternative will provide only for the average daily demands of the CCSD and does not provide for the water demands of the other public water supply systems in the county. Therefore, it does not meet the goals that were established in the purpose and need of this project. Nor will it insure a release of minimum flow in the First Broad River during low flow or drought periods. 2.2.5 Construction of Several Intakes with Storage Reservoirs This alternative is not feasible due to lack of suitable areas to construct reservoirs along the First Broad River upstream of the CCSD water treatment facility and the cost of pumping facilities for each reservoir. 2.2.6 Increase Size~eld of Existing Reservoir Not applicable in the case of CCSD as there is no existing reservoir. 2.3 MINIMIZATION ALTERNATIVES 2.3.1 Combine Water Conservation With Applicant's Proposal The water conservation program will continue to be in place as a voluntary program, which has public acceptance. Efforts to expand the conservation program will continue, but even at the most successful, water conservation will not be able to minimize the amount of water supply by any appreciable amount. A stricter, more mandatory program would not be acceptable to the public, especially to the extent of not expanding the water supply. 2.3.2 Combine Groundwater Use With Applicant's Proposal Groundwater ca.n be used for individual residences in areas where groundwater pollution is not a problem. Small users are most cost effective for groundwater sources in the county. There are no large aquifers, so the CCSD would have to utilize multiple wells in numbers and locations all through the county to create a groundwater source to supplement the river intake. This system of widespread wells would not be cost effective due to pumping and piping needs. 2.3.3 Reduce the Size of the Reservoir For Applicant's Proposal CCSD proposes to build the reservoir at the minimum elevation (860 msl) that will provide the safe water yield that is needed for growth in the county. Other higher elevations were considered, but would not provide a reasonable yield based on costs and would impact a greater area without additional benefits acceptable to the community and landowners. 2.3.4 Continue Use of Existing Water System with Construction of a Smaller Reservoir Construction of a smaller reservoir is limited by several constraints -the minimum hydraulic elevation to supply water to the existing water treatment plant is 839 msl, the smallest impoundment possible. Evaluating the safe water yield at 850 msl, the safe yield would be 19.0 MGD to the CCSD system. This yield would not be adequate for CCSD, City of Shelby and instream flow requirements. At an elevation of 860 msl, the safe yield increases to 34.0 MGD, which is adequate to provide flows for all uses downstream. Higher elevations were only considered for the additional cost benefit and were not found to be feasible. The smallest reservoir possible to achieve the needs of the CCSD and insure instream flow was proposed 2.3.5 Combine Waste Water Flow Augmentation with River Intake No wastewater flows are available for augmentation of the water supply in the CCSD 2.4. CONCLUSION The CCSD has carefully considered the various alternatives presented above to determine how each could be implemented to fulfill the purpose and need. Table 2 presents the information for the various alternatives in tabular form for comparison. Only two alternatives are considered feasible from an economic and environmental standpoint. These are the traditional reservoir and the river intake with one storage reservoir. The traditional reservoir will provide more water for multiple uses over a longer period of time than the storage reservoir. The traditional reservoir will provide 34 MGD year round as compared to 11 MGD for 3 months during low flow periods. The traditional reservoir will provide water for downstream users and maintain the minimum flows needed in the river while the storage reservoir will not be able to provide any water for downstream needs. Cost will be greater to construct the traditional reservoir, $36M as compared to $22M. Other factors to consider include the environmental impacts and the effect of conversion of stream to lake habitat. The traditional reservoir will impact substantially more stream length, converting 24 miles of streams to lake habitat while the storage reservoir will only impact 5 miles of stream. The traditional reservoir will impact one population of the federally threatened plant, Hexastylis nan~ora, requiring plant relocation. Two species of crayfish listed by the state are thought to be present, and, if that is true, a suitable mitigation plan will need to be implemented. There are two small wetland areas within the area to be flooded by the traditional reservoir, totaling 0.067 acres. These impacts would be offset by the creation of lake habitat that will provide other species with suitable nesting and feeding sites, such as waterfowl and eagles. The fishery will change from a stream to a lake, providing recreational opportunities not previously available. The riparian buffer will be enlarged and protected. Other measures will be taken to improve and protect water quality on the First Broad River. The river intake with a storage reservoir will have less environmentally adverse effects. The storage reservoir will have similar benefits, but less extensive, in providing habitat for species that utilize lakes. There will be no adverse effect on threatened or endangered species. The trade off will be a smaller water supply, no emergency backup, no instream releases for the First Broad River, and no regional considerations. 3.0 Existing Conditions 3.1 Climate The region has a moderate climate with an average annual temperature of approximately 59 degrees F and average annual precipitation of about 48 inches. The frost-free season is approximately 182 days and there is no prolonged wet or dry season. 3.2 TopographX The headwaters and major tributaries of the Broad River begin in the Blue Ridge Mountains of western North Carolina and flow through the foothills and piedmont of North Carolina before entering South Carolina. The Piedmont is an uplifted peneplain in various stages of dissection, with a general slope from the mountains on the west to the coastal plain on the east. In most of Cleveland County, the topography consists of rolling to hilly lands. In the area of northern Cleveland County, the mountain ridges feed headwaters of tributaries to the First Broad River. The project elevation starts at 880 feet in northwestern Cleveland County to approximately 790 feet near Lawndale at the proposed dam. Local relief ranges from 120 to 210 feet and averages 200 feet. Generally, the primary impact area of the First Broad River Reservoir project is characteristic of the regional piedmont physiographic province. The land use in the First Broad River sub-basin is primarily forested with 74% wooded, 22% in pasture, 2% urban, and the remaining 2% in water or cultivated. 3.3 Ge loav The proposed project area is underlain by rocks of the Inner Piedmont belt, which is the most intensely deformed and metamorphosed segment of the Piedmont, including metamorphic rocks ranging from 500 to 750 million years in age. They include gneiss and schist that have been intruded by younger granitic rocks. Crushed stone for aggregate and building construction is the principal commodity associated with these formations; however, the mineral resources are relatively unimportant to the economy of the area. 3.4 Air ualit The North Carolina Administrative Code and the Clean Air Act Amendments of 1990 establish ambient air quality standards for ground level concentrations of various air pollution parameters. Cleveland County is currently classified as an attainment area, meaning that ambient air quality standards are being met. 3.5 Vegetation Resources Plant Communities within the boundaries of the proposed Cleveland County Reservoir were surveyed in October 2004 following the 860 foot elevation contour of the First Broad River and its tributaries. The topography ranges from broad alluvial flats to extremely steep slopes. Much of the land is being used for agriculture, leaving relatively narrow strips of natural vegetation along the river and streams. Even the "natural" vegetation has been disturbed by logging or grazing in many places, significantly altering its appearance and species composition. Much of the forest vegetation above the floodplain consists of young, early-successional stands. Four plant communities were identified, using Schafale and Weakley's Classijication of the Natural Communities of North Carolina, Third Approximation (1990). These four communities are distributed roughly in narrow bands, starting at the river and moving outward and upward. There is some blending of communities where they meet. On some steep slopes, the bands are so narrow that they may not all be distinct. By far, most of the natural vegetation remaining within the impoundment zone is Piedmont /Low Mountain Alluvial Forest. This community occupies all of the floodplain of the river and its tributaries. It is dominated by river birch (Betula nigra), tulip poplar (Liriodendron tulipifera), sycamore (Platanus occidentalis), red maple (Ater rubrum), and black walnut (Juglans nigra) in the canopy. Box elder (Ater negundo), ironwood (Carpimrs caroliniana}, and American holly (Ilex opaca) are common in the understory. These understory species also dominate the shrub layer except where they have been displaced by invasives such as Chinese privet (Ligustrum sinense), multiflora rose (Rosa mult~ora), and Japanese honeysuckle (Lonicera japonica}. Doghobble (Leucothoe fontanesiana) is sometimes present on stream banks. River cane (Arundinaria gigantea) occurs sporadically. Herbs are probably numerous and abundant, but few were evident following the recent floods. Poison ivy (Toxicodendron radicans) is plentiful. Mesic Mixed Hardwood Forest--Piedmont Subtype occurs just above the Alluvial Forest, especially on gentle to moderate, moist slopes. Its canopy is dominated by tulip poplar, beech (Fagus grandifolia), red maple, and red oak (Quercus rubra). Basswood (Tilia americana var. heterophylla) is sometimes present. The understory contains flowering dogwood (Corrrus jlorida), red maple, American holly, and box elder. The shrub and herb layers have been modified by grazing. Holly is often the dominant shrub. Christmas fern (Polystichum acrostichoides) is a conspicuous herb. Dry-Mesic Oak-Hickory Forest is usually found above the Mesic Hardwood Forest, where conditions are a little drier, but still somewhat moist. White oak (Q. alba), red oak, and various hickories (Carya sp.) dominate the canopy. Pines (Pinus sp.) may be present, especially on disturbed sites. The understory includes red maple, flowering dogwood, sourwood (Oxydendrum arboreum), black gum {Nyssa sylvatica), and American holly. The shrub layer is usually sparse, partly as a natural condition and partly because of grazing. Holly is often the dominant shrub. Herbs are few and sparse. Dry Oak-Hickory Forest occupies the driest sites. It is found mainly on steep, exposed, sunny slopes. The canopy is dominated by white oak, southern red oak (Q. falcata), and a mix of pine species. Some hickories and other oaks are occasionally present. Sourwood, black gum, and American holly are common understory species. Holly is the dominant shrub on these sites, probably because of disturbance. Herbs are few and sparse. Very little of this community is present. 3.6 Water Resources The First Broad River is the largest watershed within Cleveland County and drains most of the county into the Broad River Basin. The Broad River drainage basin in North Carolina contains approximately 1,513 squaze miles (968,320 acres), with approximately 240 square miles (153,600 acres) lying within the First Broad River basin. From the confluence of the Broad and First Broad, the river flows southeast into South Carolina, north of Gaffney, and joins the Saluda River to form the Congaree River at Columbia, South Cazolina. The river eventually joins with the Wateree River prior to reaching the Atlantic Ocean as the Cooper River at Charleston, South Carolina. The North Carolina. Division of Water Quality has described water quality in this sub- basin as good. Benthic macroinvertebrate data from three (3) sites on the First Broad River have all resulted in good bioclassifications. Hickory Creek in Shelby is the only stream in this sub-basin that has been identified as impaired. The First Broad River watershed is currently classified for potable water supply and has a classification of WS- III upstream of the CCSD intake. 3.7 Wetland Resources Two areas were found during the stream and river pedestrian surveys that were deemed potential wetlands. Subsequent investigation determined that two wetlands are present along two tributaries that feed the First Broad River at the Clover Hill Church Road bridge. Just upstream of the bridge, there are four tributaries that enter the First Broad River. From downstream to upstream, the first and fourth tributaries have no wetlands associated with it. The second tributary has riparian wetlands on the point bazs and flood plains. The soils were 10YR4/1 clay with no mottles. Vegetation was mostly lacking in the herbaceous layer. Trees in the vicinity included American holly, American elm, and persimmon. The shrubs present were privet and musclewood. The predominant vegetation was FAC. Hydrology indicators included saturation in upper 12 inches and sediment deposits. The total size was approximately 300 square feet. The third tributary had two areas of potential wetland. The downstream azea had saturated soil and free water in the pit at 10 inches. The hydrology indicators present were saturated soil, sediment deposits and drainage patterns. There were seven species of hydrophytic vegetation identified and four species of upland vegetation. Hence, this fits the criteria necessary for wetland status. The soils showed 7.SYR3/3 in the upper 8 inches, 7.SYR4/1 with mottles in the next 4 inches, and 7.SYR4/6 with mottles of 7.SYR4/1 from 12-18+ inches. Although the soils are somewhat ambiguous as to hydric characteristics, it was concluded that this is a wetland. The total area was 2772 square feet. The wet area further upstream on the third tributary is an old farm pond that has filled in and the dam has been breached. The stream has two branches in this area with the main channel on the east side of the old pond. Hydrophytic vegetation was present. Hydrology indicators included sediment deposits and drainage patterns. Water stained leaves were present in some of the lower areas. The soils did not exhibit clear cut indications of hydric conditions. The upper 5 inches showed 7.SYR4/1 sandy clay, but the next 13+ inches yielded 7.SYR4/4 clayey sand. No mottles were present. It appears that the upper portion of the soil having a higher clay content holds the water and has hydric characteristics. The deeper soils are not saturated, the high chroma indicates oxygen present, and fluctuations of the water table that would result in oxidation reduction are not occurring. Therefore, it was concluded that this is not a wetland. Approximately half of the old pond is within the area to be flooded. The old pond is 0.3 acres in size. 3.8 Wildlife Resources No unique wildlife resources are known to exist in the project area. The riparian zone of the First Broad is continuously wooded in a narrow band providing a wildlife corridor. 3.9 Fishery Resources The fishery resources will be surveyed in 2005 in both the river and the tributaries. Preliminary investigations note that the river supports a warm water fishery with sunfish common in the river. NC DENR fish surveys conducted in the year 2000 in wadable streams of this river basin found 13 to 15 fish species in tributaries to the First Broad River. These species included 2-3 species of darters, 2 species of suckers, and 1 species of sunfish/bass/trout. Both sites had lower than expected fish species and only one species of sunfish was present in both streams. No piscivores were present in either stream. 3.10 Endangered. Threatened, and Rare Species The North Carolina Natural Heritage Program lists 33 rare species for Cleveland County. This includes 4 federally listed species: 0 endangered, 1 threatened, and 3 species of concern. The federally threatened small-flowered heartleaf, Hexastylis nan~ora, was found on north facing banks above the main tributary of the First Broad River where Clover Hill Church Road crosses the river. Approximately 100 plants were found. All other areas having Pacolet, Madison or Musella soils were surveyed, but no plants were found. The three federal species of concern included the Diana fritillary (Speyeria diana), Sweet pinesap (Monotropsfs odorata), and Carolina saxifrage (Sax~aga caroliniana). None of these species were observed during the various field investigations. Host plants, violets, for the Diana fi-itillary are present in the project area. State species of concern include two crayfish found in the Broad River basin: Broad River Stream Crayfish (Cambarus lenati) and Broad River Spiny Crayfish (Cambarus spicatus). The tributaries of the First Broad River that will be impacted by the project will be surveyed for crayfish in the spring of 2005 to determine if the species of concern are present in the project area. 3.11 Unique Natural Areas and Scenic Rivers There are no designated natural areas or scenic rivers within the project boundaries. 4.0 Archaeological and Cultural Resources 4.1 Cultural Resources The First Broad River Reservoir, Cleveland County, NC has relatively few known cultural resource sites. Archaeological and architectural surveys have been conducted to identify archaeological and architectural resources in the project area, and where possible, to determine if these resources are potentially eligible for inclusion in the National Register of Historic Places. For the archaeological and architectural surveys, the project area was that defined in Section 4.1 above. 4.2 Prehistoric and Historic Archaeological Resources No previous comprehensive survey of Cleveland County had been done. Few sites have been recorded in the county and none within the project boundaries. A Phase I archaeological survey of the area within the present project boundary was performed (Joy and Carruth, July 2003). Of the 1200 acres, approximately 100 acres is existing waterway. Landowners denied permission to survey on 206 acres, or approximately 20%. Of the remaining 894 acres, a total of 790 acres, or 72% of the total 1100 acres was surveyed. The survey in the proposed project flood pool consisted of surface reconnaissance and subsurface shovel testing. There were sixteen (16) archaeological sites identified within the study area, with seven sites historic and nine sites prehistoric. An evaluation of all sixteen sites was made on potential eligibility for the National Register of Historic Places (NRHP) and two sites met the criteria. Both of the potentially eligible sites were prehistoric sites and if they cannot be avoided during the project, then additional archaeological work will be needed. In addition, those properties that were inaccessible due to landowners refusing permission to survey will need to be surveyed after acquisition. The references for the archaeological site reports resulting from this survey can be found in the references cited section and are incorporated herein by reference. 4.3 Architectural Resources No architectural resources were identified within the project area. 5.4 Mitigation Plan The environmental consequences of constructing a large reservoir can potentially have very extensive effects on the aquatic and terrestrial resources. The proposed reservoir on the First Broad River has the advantage of relatively few permanent impacts to wildlife and aquatic communities since the lake will not flood out over flat land, but rather rise within the banks and adjacent slopes. There are three species of concern in the project area, 24 miles of stream habitat, 1500 acres of forested/agricultural land, and 0.06 acres of wetland that will be affected by the project. 5.1 Avoidance and Minimization Avoidance measures will include protection of the river during construction activities. A buffer will be maintained along the river during the clearing phase. Appropriate Best Management Practices will be employed to minimize impacts to the river during construction of the dam. Sediment basins/traps, check dams, and diversion will be utilized as appropriate to control erosion and sedimentation. Access roads will be restricted and kept to a minimum. 5.2 Nfiti ation Mitigative measures will address the species of concern, the loss of stream in the dam footprint, the conversion of stream to lake aquatic habitat, and the loss of terrestrial habitat. Consultation with the US Fish and Wildlife Service will be initiated concerning the Hexastylis nan~ora population present within the project area. Depending on the decision reached, the plants may be moved upslope, but within the same general locale. Or, the plants may be relocated to another site along a stream where suitable habitat exists. Wildlife habitat will be maintained by establishment of a forested buffer around the new reservoir. The minimum amount of buffer will be increased to provide a forested corridor of at least 100' around the entire lake with larger tracts of adjacent land as available. Any plantings will be limited to native species with emphasis on value to wildlife. Land acquisition will result in many tracts being larger than just the amount needed for the reservoir. These lands will be maintained as natural areas, forested or allowed to return to forest, managed as gamelands in conjunction with the NC Wildlife Resources Commission. Such areas will be held by the County for public use. A lake fishery will be developed in the new reservoir in cooperation with the NC Wildlife Resources Commission. Many of the fishes present in the river will be able to survive and flourish in the lake. As construction of the reservoir progresses, fish habitat will be developed along the shoreline. Fish attractors, such as logs and partially submerged snags, will provide cover. Inundated plants in the upper end of coves will provide both shelter and spawning areas. Selected trees may be retained to provide roosting and nesting sites for ducks, eagles, kingfishers, and similar species. Additional conservation easements on the tributaries and headwaters around the lake and in other areas of the County will be pursued to provide vegetated buffers along all water courses. Erosion and sedimentation control as well as stream restoration will be funded through the MRCS and other appropriate agencies. Recreational projects such as development of a public boat launch area with parking, public bank fishing access, and picnic facilities will be developed in consultation with the Wildlife Resources Commission and Parks & Recreation. ., _.~ LLE % KEN ~""~' ^'~ \ 1 i ,,,n x, U `z`.. ~ ~ 't7. •~~~ \ .
