Paragraph 19(c). Paragraph 19 of the Consent Order also requires that ‘Permanent replacement drinking water supplies established pursuant to this paragraph shall be installed no later than: (i) nine (9) months from the date Chemours becomes aware that the affected party qualifies for replacement drinking water; or (ii) if Chemours is aware that an affected party qualifies for replacement drinking water at the time this Consent Order is entered, nine (9) months from the date of entry of this Consent Order.” Chemours directed its consultant Parsons to investigate comprehensively the extent to which public water connections are feasible for the impacted homes that have been found to exceed the 140 ng/L standard for GenX compounds. As part of this investigation, Chemours has also had discussions with officials from both Bladen and Cumberland Counties about the potential for connections to their respective public water systems. Attached please find the Feasibility Study Report (the “FS Report”) for Public Water Services, Chemours Fayetteville Works Fayetteville, North Carolina, prepared by Parsons on behalf of Chemours, June 2018, and the January 2019 updated analysis. As you will see in the FS Report, as a result of differences in existing municipal water infrastructure, geography, and home density, the analysis focuses separately on each of four areas: (1) Bladen County west of the Cape Fear River, (2) Bladen County east of the Cape Fear River, (3) Cumberland County west of the Cape Fear River and, (4) Cumberland County east of the Cape Fear River. The report evaluates the extent to which the provision of municipal water to homes in these areas is technically feasible and addresses the availability of existing infrastructure and whether water of sufficient quality could be provided. It also assesses whether the installation of public water is cost-effective, applying the Consent Order standard. Also considered are the current state of the municipalities’ planning, and, relatedly, whether municipal water can be installed in a timely fashion in each area. The FS Report notes that public acceptance of municipal water connections will affect both feasibility and cost. As noted above, Chemours had a number of discussions with officials for both Bladen and Cumberland counties; the FS Report reflects those discussions. There are 49 eligible households in Bladen County west of the Cape Fear River that are presently eligible for connection to public water.1 The total cost of installing public for these 49 household is approximately $3.47 million. Of the 49 eligible households, 13 homes in Bladen County west of the Cape Fear River are next to an existing water main and the running of a lateral connection is feasible, safe, and can be completed within nine months (assuming that all necessary permits and approvals can be obtained in a timely fashion). Chemours will connect any of these 13 homes that select this option to public water. The remaining 36 homes present both cost and timing challenges, as connection to public water requires the installation of both a water main and a lateral connection. This significant work cannot be completed within the nine months, as required by the Consent Order. We estimate based on discussions with Bladen County that the 1 Two additional homes have eligible wells but are already connected to public water and therefore are not included in this analysis. The Chemours Company Fayetteville Works 22828 NC Highway 87 W Fayetteville, NC 28306 installations would be completed in approximately two to four years. For example, before public water can be extended, the County must obtain rights of ways and permits, and even these initial steps will take longer than 9 months. Therefore, we request that DEQ extend the 9-month implementation requirement if a sufficient number of these homes request a public water connection so that that connection is not “cost prohibitive.” In the event that NCDEQ is willing to extend the installation period, Chemours proposes to connect these 36 homes to public water as long as a sufficient number of the homes agree to be connected to public water. For public water to these Bladen County west of the Cape Fear River homes to stay below the “cost prohibitive” threshold, at least 30 of the 36 homes would have to agree to be connected to public water. If only 29 homes, plus the 13 homes described above, agree to be connected to public water, the cost per home would be “cost prohibitive” at $83,000. In short, Chemours seeks your approval to proceed as follows: • The 13 homes requiring only a lateral connection to be connected to public water would be offered either a public water hook up (with water bills to be paid by Chemours for 20 years), a whole house filtration system, or reverse osmosis systems on every kitchen and bathroom sink. • For the remaining 36 homes, assuming that NCDEQ agrees to an implementation extension, Chemours would ask the homeowners preference, and if at least 30 homeowners opted for public water (with water bills to be paid by Chemours for 20 years), then that option would be available. If fewer than 30 of the homes agree to be connected to public water, all homes would be provided with the options of a GAC system or reverse osmosis units on every kitchen or bathroom sink. • If no extension for implementation is granted, the 36 homes would be provided with the options of a GAC system or reverse osmosis units on every kitchen or bathroom sink. • If a sufficient number of homes agree to a public water connection such that the cost remains below the “cost prohibitive” threshold, these homes would be offered a reverse osmosis system while waiting for the installation of public water. For the 84 homes in Cumberland County west of the river, the lack of existing infrastructure and a definitive source of water means, as explained in the FS report, that the provision of municipal water is not currently feasible and is cost prohibitive, with estimated per home costs of $233,800. We seek your concurrence in that determination, so we can move forward expeditiously in offering for these homes whole house filtration or reverse osmosis systems on every kitchen and bathroom sink. In both Bladen and Cumberland Counties on the east side of the river, as explained in the FS report, municipal water is not technically feasible: there is no existing source for water, the long distance between possible sources and the low density of houses means that there would be poor water quality, and as there is little to no infrastructure it would be many years before municipal water could be installed. These challenges also result in costs that are prohibitive. For the five eligible homes in Bladen County, the cost would be approximately $354,000 per home. For the 44 eligible homes in Cumberland County, the cost would be approximately $272,000 per home. We seek your concurrence in that determination, so we can move forward expeditiously in offering the option of either whole house filtration or reverse osmosis systems on every kitchen and bathroom sink. Please let me know if you require any further information to make your determinations, or if you would like to discuss the matter. Sincerely, Brian D. Long Plant Manager Chemours – Fayetteville Works The Chemours Company Fayetteville Works 22828 NC Highway 87 W Fayetteville, NC 28306 Enclosure: Public Water Report March 11, 2019 via email: Kevin.Garon@Chemours.com Mr. Kevin P. Garon Principal Project Director Chemours Corporate Remediation Group Subject: Provisions for Public Water Chemours Fayetteville Plant Dear Mr. Garon, On February 25, 2019, Chemours entered into a consent order with the NCDEQ dealing with several items related to perfluoroalkyl and polyfluoroalkyl substances (PFAS) at the Chemours Fayetteville Works site. In particular condition 19 requires Chemours: establish and properly maintain permanent replacement drinking water supplies in the form of public water or a whole building filtration system for any party (i.e., household, business, school, or public building) with a private drinking water well that has been found through testing validated by DEQ to be contaminated by concentrations of GenX compounds in exceedance of 140 ng/L, or any applicable health advisory, whichever is lower. Under this provision, permanent replacement water supplies shall be established by connection to a public water supply… The consent order allows for exceptions to providing public water where the homeowner rejects the offer, elects to receive a whole house or under sink filtration system, or “if DEQ determines that connection to a public water supply to an affected party would be cost-prohibitive (i.e., greater than $75,000) or unsafe…” In June 2018, Parsons prepared a report estimating the cost to provide public water to these residents1. The purpose of this letter is to provide updated cost and technical feasibility information for providing public water to residents as outlined above. BACKGROUND Chemours has had several meetings and phone calls with representatives of Bladen and Cumberland Counties to discuss issues and timing related to possible connections of impacted homeowners to municipal water. Most recently, on December 10, 2018, Chemours and Parsons had phone conversations with officials from both counties to get updated cost and schedule information. Bladen County Bladen County operates a public water system that draws water from groundwater and that currently serves select areas of the county as well as providing wholesale water to Cumberland County to service a small neighborhood in southwestern Cumberland County (SouthPoint). Bladen County has several wells located around the county. The system is divided into geographic areas, and service is currently available in the northwestern portion of the county and a small area in southwestern Cumberland County. Parsons has been working with the county to obtain maps and determine requirements for expanding the existing systems. Two proposals were provided by Bladen County to Chemours in late 2017 for providing service to the area west of 1 Feasibility Study Report for Public Water Services, Chemours Fayetteville Works, Fayetteville, North Carolina. June 29, 2018 (Attached). Kevin Garon Chemours Corporate Remediation Group Provisions for Public Water March 11, 2019 Page 2 of 5 the Cape Fear River. Parsons estimated the costs to provide water to the residences on the east side of the river based on the location of existing water mains and the distance to impacted homes. Cumberland County Cumberland County currently operates a small public water system serving the SouthPoint neighborhood located off Chicken Foot Road in southwest Cumberland county. The county purchases water from Bladen County to service this small neighborhood of less than 50 homes. The County has identified the expansion of municipal water as a priority and is conducting an evaluation of such an expansion. Currently, the only water service in southern Cumberland County is in the South Point neighborhood. While Cumberland County operates the system, wholesale water is purchased from Bladen County for this small system. Cumberland County evaluated expanding municipal water to residences as part of a proposed bond issue, prepared a preliminary engineering report (PER) for providing public drinking water to various areas of the county not currently served by the utility (Cumberland County Rural Water Feasibility Study Preliminary Engineering Report, August 2009). The PER outlined the cost to expand the system to rural areas located outside the current areas of service. Parsons has been in discussions with representatives from Cumberland County about this study, a portion of which is being updated. The County is updating the portion of the study related to the Grays Creek Water and Sewer District (the southwest portion of the county). While the report has not been finalized, the County provided updated cost estimates to Chemours for this area. COST ESTIMATES For this analysis the area around the Fayetteville works site has been divided into four service areas as shown on Figure 1. The service areas are based on the most likely service provider and geography (Bladen County east of the Cape Fear River, Bladen County west of the Cape Fear River, Cumberland County east of the Cape Fear River, and Cumberland County west of the Cape Fear River). Bladen County East of the Cape Fear River As shown on Figure 1, there are only five residences whose drinking water sampling results are at or above 140 parts per trillion (ppt) within this area. To provide service to Bladen County east of the Cape Fear River from existing sources, installation of an approximately 16,100 linear foot (LF), 6-inch water main would be required to bring water to the area from the existing water service on River Road. An existing groundwater well feeds this system and is assumed to be sufficient for the limited number of homes (five) at which the health advisory level has been exceeded. As an alternative, a water line could be extended from the existing Bladen County system west of the Cape Fear River. However, the length of the line, the need to acquire significant right-of-way, and the cost of drilling underneath the Cape Fear River make this option infeasible. Regardless, the long water main and limited number of customers would require that flushing hydrants be installed to maintain the water quality. The flushing hydrants would result in wasting significant amounts of water. The hydraulics and system capacity indicate that it would be extremely difficult to maintain appropriate water quality over this distance given the number of homes. The construction of a new and long water main to carry water to the five homes in Bladen County east of the Cape Fear River, along with connecting the five homes, is estimated to cost $1,770,000 – approximately $354,000 per house. The cost details are summarized in the June 2018 Feasibility Study. In addition, Parsons estimates that design, permitting, and construction of this system would take two to four years to complete. Kevin Garon Chemours Corporate Remediation Group Provisions for Public Water March 11, 2019 Page 3 of 5 Based on the cost, schedule, and technical limitations, it remains impractical to provide public water to this area. Bladen County West of the Cape Fear River As shown on Figure 1, there are 492 residences whose drinking water sampling results are at or above 140 ppt within this area. It is anticipated that municipal water could be expeditiously provided to impacted homes in this area, since existing water service lines are already present in much of the area, and only moderate water main additions are necessary to extend the water service lines to all impacted homes. The existing Bladen County water supply well is reportedly nearing capacity, and the expansion of municipal water service to additional homes likely will require drilling a new well. Based on information provided by Bladen County, Chemours estimates the cost of installing municipal water to all 49 homes in Bladen County west of the Cape Fear River at $3,470,000 -- approximately $70,816 per home. The new well accounts for approximately 25% of the total cost for extending service in Bladen County west of the river. It is estimated that construction of the system would require two to four years to complete (assuming the State will fast track the permitting process). Of the 49 homes, there are approximately 13 homes that have an existing water main in front of the property. Providing these homes with water can be accomplished quickly and with only minimal costs (within 9 months and below the $75,000 per home threshold). The remaining 36 homes require significant infrastructure installation (a new well and additional distribution mains) to connect to public water. In addition, for the cost to stay below the “cost prohibitive” threshold, at least 30 of these homes would have to agree to be connected to public water. Given that, we recommend: • The 13 homes requiring only a lateral connection water would be offered either a public water hook up (with water bills to be paid by Chemours for 20 years), a whole house filtration system, or reverse osmosis systems on every kitchen and bathroom sink. • For the remaining 36 homes, assuming that NCDEQ agrees to an extension to the time required for installation, Chemours would ask the homeowners preference, and if at least 30 homeowners opted for public water, then that option would be available. If fewer than 30 of homes agree to be connected to public water, all homes would be provided with the options of a GAC system or reverse osmosis units on every kitchen or bathroom sink. • If no extension for implementation is granted, the 36 homes would be provided with the options of a GAC system or reverse osmosis units on every kitchen or bathroom sink. • If a sufficient number of homes agree to a public water connection such that the cost remains below the “cost prohibitive” threshold, these homes would be offered reverse osmosis systems while waiting for the installation of public water. Cumberland County East of the Cape Fear River As shown on Figure 1, there are 44 residences whose drinking water sampling results are at or above 140 ppt within this area. To provide municipal water to these homes, a water main must be extended from Fayetteville PWC to the south. This service area would require extending a 31,500 LF, 12-inch main from the intersection of NC 210 and Cedar Creek Road (in addition to the smaller mains to service the homes). The long water main and limited number of customers may result in water quality issues within the service area. Parsons’s initial analysis indicates that appropriate water quality would be difficult to maintain, given the hydraulics and capacity of the system. 2 Two additional homes have eligible wells but are already connected to public water and therefore are not included in this analysis. Kevin Garon Chemours Corporate Remediation Group Provisions for Public Water March 11, 2019 Page 4 of 5 The estimated cost of providing municipal water to the 44 residences in Cumberland County east of the Cape Fear River, is $12,000,000. This is over $272,000 per house. The main cost driver is the long distance from an existing public water source. Given the current lack of municipal water infrastructure, a new and long water main must be constructed to reach these 44 households. Parsons estimates that such installation would take approximately five to eight years to construct. It is not feasible, technically or in terms of cost and timeliness, to install municipal water east of the Cape Fear River in Cumberland County. Given the existing lack of municipal water infrastructure, distance to the nearest water mains, and the lower density of homes, installing municipal water means that these residences will be on bottled water for years. Further, servicing these areas from the existing PWS will require long dead-end water mains that add significant cost to the system and may not provide a water supply of adequate quality. Cumberland County West of the Cape Fear River As shown on Figure 1, there are 84 residences whose drinking water sampling results are at or above 140 ppt within this area. As previously mentioned, Parsons met by phone with Jeffrey Brown from Cumberland County on December 10, 2018 to discuss their updated cost estimates for providing water to this area of the county (designated the Grays Creek Water and Sewer District or the Southwest District by the County). Cumberland county provided updated cost estimates for providing water service to the entire district as well as only the area where wells have exceedances of the health goal. Based on these estimates, the cost to provide water to the 84 residents in this area would be approximately $19,640,000 or $233,800 per home. Mr. Brown estimated that construction of this system would take approximately three to four years to complete. Based on the cost (greater than $75,000 per home) and the schedule (three to four years), it is considered impractical to provide public water to homeowners in this area. ● ● ● Parsons appreciates the opportunity to assist Chemours with addressing this very important project.

Parsons has prepared this Feasibility Study (FS) Report to evaluate the potential for extending existing public water systems (PWSs) into the area around the Chemours Fayetteville Works Plant located near Duart Township in Bladen County, North Carolina (the Site). Expanding public drinking water access to impacted areas around the Site and providing connections to homes is a possible measure to address exceedances of the provisional health goal for HFPO-DA in private wells. Chemours, in coordination with NCDEQ, is also conducting a pilot program on the effectiveness of granular activated (GAC) filtration systems in removing HFPO-DA from water. The initial results from the pilot program demonstrate that the GAC system is highly effective at removing HFPO-DA and can be effectively utilized if either (i) the homeowner prefers the GAC system or (ii) the extension of the PWS to that homeowner is not cost effective. Chemours has had several meetings and phone calls with representatives of Bladen and Cumberland Counties to discuss issues and timing related to possible connections of impacted homeowners to municipal water. Most recently, on June 21, 2018, Chemours met with County officials, including the County Administrators for Bladen and Cumberland Counties to share information about such potential connections. The Counties and Chemours agreed to continue to work together on the feasibility, scope and implementation of connection to PWS. 2.0 BACKGROUND AND OBJECTIVES The Site is located on NC Highway 87, 15 miles southeast of the City of Fayetteville and south of the Bladen-Cumberland county line. The Site encompasses 2,177 acres of relatively flat, undeveloped open land and woodland bounded on the east by the Cape Fear River, on the west by NC Highway 87, and on the north and south by farmland (Figure 1). E.I. du Pont de Nemours and Company (DuPont) purchased the property in parcels from several families in 1970. A former manufacturing area, which was sold in 1992, produced nylon strapping and elastomeric tape. DuPont sold its Butacite® and SentryGlas® manufacturing units to Kuraray America Inc. in June 2014. On July 1, 2015, DuPont separated its specialty chemicals business into a new publicly-traded company named The Chemours Company FC, LLC. With this separation, Chemours became the owner of the entire 2,177 acres of the Fayetteville Works along with the fluoromonomers, Nafion™ membranes, and Polymer Processing Area (PPA) manufacturing units. The polyvinyl fluoride (PVF) resin manufacturing unit remains with DuPont. FEASIBILITY STUDY REPORT FOR PUBLIC WATER SERVICES BACKGROUND AND OBJECTIVES US:162910190v10 2 2.1 Regional Topography, Geology and Hydrogeology The region surrounding the Site is generally level to gently sloping. However, surface topography steepens when approaching the Cape Fear River and its tributaries. The Chemours Site is in the northwestern portion of Bladen County at the southern border of Cumberland County. Cumberland and Bladen Counties are situated within the Coastal Plain Physiographic Province, which consists of a seaward thickening wedge of sedimentary deposits ranging in age from Cretaceous to Recent. Paleozoic, metamorphic and igneous rocks underlie these deposits. In the northern portion of Bladen County these “basement” rocks are approximately 400 feet below ground surface (bgs). Based on the Geologic Map of North Carolina1, Bladen and Cumberland counties is underlain by the Black Creek Formation. The Black Creek Formation is characterized by lignitic clay, gray to black, and contains thin beds and laminae of fine-grained micaceous sand as well as thick lenses of cross-bedded sand. The upper portion of the formation may also contain glauconitic, fossiliferous clayey sand lenses. The Black Creek Formation and surficial deposits are the principal potable water aquifers in the region. Shallow groundwater is generally encountered between 15 and 40 feet below grade. The soil in Bladen and Cumberland counties falls within the Norfolk-Goldsboro-Raines general classification2. These soils are located on old, high stream terraces in the northern part of Bladen County and are generally poorly drained soils that have a sandy or loamy surface layer and loamy subsoil. Based on the lithology logged during on-site investigations, the Site is underlain by a fine- to medium-grained sand unit with thin discontinuous interbedded silt/clay lenses. The sand extends to a depth of approximately 65 feet bgs (elevation of +80 feet mean sea level [MSL]). The saturated portion of this unit has been identified as the Surficial Aquifer. Beneath this unit is a 7- to 15-foot-thick, laterally-continuous dense clay that has been identified as the Black Creek Confining Unit. 2.2 Feasibility Study Objectives The purpose of this FS is to: 1. Analyze the potential for expanding public drinking water access to homes with private wells having concentrations exceeding the North Carolina provisional health goal for HFPO-DA. 2. Provide a plan for providing required access where such expansion is determined to be feasible. This report presents the potential options for providing public drinking water to impacted homes around the plant, provides the estimated cost and timeframe to construct the systems, and evaluates the ability to implement the options presented. 1 North Carolina Geological Survey. 1985. 2 Leab, Robert J. 1990. Soil Survey of Bladen County. United States Department of Agriculture, Soil Conservation Service. FEASIBILITY STUDY REPORT FOR PUBLIC WATER SERVICES PROPOSED SERVICE AREAS AND WATER SOURCES US:162910190v10 3 3.0 PROPOSED SERVICE AREAS AND WATER SOURCES To facilitate the analysis, the area around the plant was divided into four proposed service areas (based on geography and proximity to water sources) as shown on Figure 2: 1. Bladen County West of Cape Fear River 2. Bladen County East of Cape Fear River 3. Cumberland County West of Cape Fear River 4. Cumberland County East of Cape Fear River Each area is discussed in detail below. In addition, there are three potential water sources for serving the four areas analyzed below. 3.1 Bladen County (Groundwater) Bladen County operates a public water system that draws water from groundwater and that currently serves select areas of the county as well as providing wholesale water to Cumberland County to service a small neighborhood in southwestern Cumberland County (SouthPoint). Bladen County has several wells located around the county. The system is divided into geographic areas, and service is currently available in the northwestern portion of the county and a small area in southwestern Cumberland County. Parsons has been working with the county to obtain maps and determine requirements for expanding the existing systems. Two proposals were provided by Bladen County to Chemours in late 2017 for providing service to the area west of the Cape Fear River (Appendix A). 3.2 Cumberland County (Groundwater or Surface Water) Cumberland County currently operates a small public water system serving the SouthPoint neighborhood located off Chicken Foot Road in southwest Cumberland county. The county purchases water from Bladen County to service this small neighborhood of less than 50 homes. The County has identified the expansion of municipal water as a priority and is conducting an evaluation of such an expansion. Currently, the only water service in southern Cumberland County is in the South Point neighborhood. While Cumberland County operates the system, wholesale water is purchased from Bladen County for this small system. Cumberland County evaluated expanding municipal water to residences as part of a proposed bond issue, prepared a preliminary engineering report (PER) for providing public drinking water to various areas of the county not currently served by the utility (Cumberland County Rural Water Feasibility Study Preliminary Engineering Report, August 2009; see Appendix B). The PER outlined the cost to expand the system to rural areas located outside the current areas of service. Three potential water sources for the proposed water system were analyzed in the PER:  Option 1 - developing a County-owned surface water supply;  Option 2- developing a County-owned groundwater supply; and  Option 3 - negotiating a purchase contract with an existing provider. FEASIBILITY STUDY REPORT FOR PUBLIC WATER SERVICES ASSUMPTIONS US:162910190v10 4 Two alternative water sources were evaluated as part of Option 3: (a) Fayetteville Public Works Commission (PWC) and (b) Lower Cape Fear Water and Sewer Authority (LCFWSA). The results of the study indicated that “existing supplies preclude the necessity for Cumberland County developing their own County water supply system (surface or groundwater).” Purchasing water from the Fayetteville PWC was determined to be the most economical option. The Fayetteville PWC uses surface water as its source. The report divides the areas into sub-sections and included population growth estimates. Parsons has been in discussions with representatives from Cumberland County about this study, which is being updated. The County is updating the study to reflect current population estimates and updated growth projections and to add provisions for fire protection service (instead of the rural water service previously proposed). Based on Parsons’ discussions with the county, we expect that Cumberland County may decide to purchase water from the Fayetteville PWC or from Bladen County. We understand, from discussions with the County, that it working to complete the updated study before October 15, 2018. 3.3 Source 3: Lower Cape Fear Water and Sewer Authority (Surface Water) The LCFWSA operates a surface water treatment plant in Tar Heel, North Carolina, approximately 5.5 miles south of the Site entrance. The treatment plant uses water from the Cape Fear River. Parsons has determined that there are no water lines extending north of the treatment plant. Therefore, the use of this plant as a source was considered impractical given that other sources are significantly closer to the Site. In addition, this system could not practically or cost-effectively serve areas east of the Cape Fear River. 4.0 ASSUMPTIONS This study relies on publicly-available data, discussions with the Counties, and system information and piping layouts provided to Parsons by the County utilities. Parsons evaluated the available data to determine the most efficient, feasible, and implementable solutions for providing public drinking water to the area. Several assumptions were made while performing the evaluation: 1. The hydraulics of a new delivery system were not analyzed. Parsons assumed that the systems and pipe sizes proposed by Cumberland and Bladen Counties will provide suitable flow and pressure to the homeowners. 2. Proposed costs were based on the costs provided in the PER (adjusted for inflation), cost estimates provided by Bladen County, and professional judgement. The PER can be found in Appendix B. The costs are intended to provide a rough estimate for each option so that a preliminary determination of the cost effectiveness of each alternative could be made. The actual cost may be higher or lower. 3. No cost contingency has been included. 4. Parsons assumed cooperation between the water utility suppliers. Negotiation for intercounty water licenses is not included. FEASIBILITY STUDY REPORT FOR PUBLIC WATER SERVICES PROCESS OVERVIEW US:162910190v10 5 5. The proposed system is for providing drinking water to affected residences and does not include fire suppression protection. 6. Piping will be installed with 3.5 feet of cover for freeze protection. Dewatering of excavation pits is not required. 7. Piping can be installed outside paved areas. 8. The construction schedule assumes an average production rate of 300 feet of pipe laid per day and working 5-day weeks, with 36 weeks of construction time per year. 9. Parsons assumed that the counties will use their powers of eminent domain to obtain the property necessary for implementation of municipal water and that Chemours will not be responsible for purchasing property. 10. This study assumes that water mains will be installed directly to the impacted areas (i.e., it does not include the buildout of other areas the transmission main may pass through). 11. Parsons also reviewed the public record related to the implementation of municipal water connections by Duke Energy to identify issues and evaluate the estimated timeline for implementation of the options reviewed in this study. 5.0 PROCESS OVERVIEW This section describes the general process that would be followed to determine whether and how Chemours would provide certain homeowners with connections to PWSs. How that general process would be applied to specific geographic areas is discussed in subsequent sections. For each owner of a home with well water concentrations above the provisional health goal, Chemours will determine in coordination with DEQ whether a connection to public water would be feasible, assuming sufficient acceptance by homeowners. Such a connection would be considered feasible if the respective County is willing to make public water available to that homeowner, and the cost to Chemours of doing so is cost-effective. Based on our understanding of the State’s practice in other situations, to assess whether it is cost effective to provide public water to each service area, the cost per home needs to be calculated. Extension of public water was initially deemed “cost-prohibitive” by the State for connections by Duke Energy when the cost exceeded $35,000 per home. It is our understanding that this value was increased by the State this year to $75,000 per home. For purposes of this report, it is assumed that connections costing over $75,000 per home are not cost effective. For reference, we understand that the cost to install a GAC filtration system is approximately $10,000 per home. If providing water service to an area is determined to be potentially feasible, Chemours will contact the owner of each home with well water concentrations above the provisional health goal to request their preference for municipal water or a GAC filtration system. Based on their preference, Chemours will obtain the necessary access agreement. If the homeowner prefers municipal water, Chemours will request that they create an account for municipal water (where existing service is available). This process is similar to the one used by Duke Energy for extending public water service to homes around their facilities. Chemours estimates, based on the Duke Energy experience, that most homes will complete these prerequisite steps within one year. Chemours also anticipates that FEASIBILITY STUDY REPORT FOR PUBLIC WATER SERVICES PROPOSED MUNICIPAL WATER EXPANSIONS BY LOCATION US:162910190v10 6 there will be several homes that will lag behind, but that these should not impact the general construction schedule unless they are at the outer limit of any municipal water line. For areas not currently serviced by an existing public water service, the PWS would only be extended if a sufficient percentage of the homes in that area select the PWS solution and the extension of service was determined to be cost effective. Otherwise, it will not be possible to deliver water of sufficient quality for drinking. The exact number of homes needed to justify the system and provide adequate water quality will be determined based on hydraulic modeling and assistance from the Counties. In addition, some homes may require minor system expansions (e.g., extension of a 2-inch water main). These homes will be evaluated on a case-by-case basis (based on factors such as the ability to obtain rights-of-way and available water supply system capacity). 6.0 PROPOSED MUNICIPAL WATER EXPANSIONS BY LOCATION As discussed above, this report focuses on four proposed service areas. The feasibility and implementability of servicing each area based on cost, ability to provide adequate water quality, and schedule is discussed in more detail below. 6.1 Bladen County As previously mentioned, Parsons has been working with each county to obtain maps and determine requirements for expanding the existing systems. Bladen County provided two proposals in late 2017 to provide service to the area west of the Cape Fear River (Appendix A). Parsons used these proposals and updated sampling results to determine the size and location of water mains necessary to service homes in this area. Bladen County is evaluating expanding both drinking water and fire suppression services to all homes in this area. In the most recent discussions with Bladen County, Chemours and Bladen County agreed to continue to coordinate on the expansion of municipal water connections west of the Cape Fear River. The next meeting will be scheduled after Bladen County has had an opportunity to review this municipal water plan. 6.1.1 Bladen County West of Cape Fear River As shown on Figure 3, there are 47 residences whose drinking water sampling results are at or above 140 parts per trillion (ppt) within this area. It is anticipated that municipal water could be expeditiously provided to impacted homes in this area, since existing water service lines are already present in much of the area, and only moderate water main additions are necessary to extend the water service lines to all impacted homes. The existing and proposed extension of water service lines is shown on Figure 3. Water would be provided by an existing groundwater well (Tobermory Road) along with a proposed new well (location to be determined). The existing Bladen County water supply well is reportedly nearing capacity, and the expansion of municipal water service to additional homes likely will require drilling a new well. According to Bladen County officials, the proposed well would have sufficient capacity to serve both this area of Bladen County and homes exceeding the HFPO-DA advisory level in the Cumberland County area to the north (also west of the Cape Fear River). FEASIBILITY STUDY REPORT FOR PUBLIC WATER SERVICES PROPOSED MUNICIPAL WATER EXPANSIONS BY LOCATION US:162910190v10 7 Estimated Cost Chemours estimates the cost of installing municipal water to all 47 homes in Bladen County east of the Cape Fear River at $3,480,000 -- approximately $74,000 per home. The costs are summarized in Table 1, and a detailed breakdown of the estimated costs is provided in Appendix C. The new well accounts for approximately 25% of the total cost for extending service in Bladen County west of the river. Estimated Schedule For homes that already have a water line to serve the house (i.e., the home just needs a service connection to the existing line), a homeowner selecting municipal water will simply be connected to the line. Accordingly, the schedule for installation in this area is shorter than in other areas, given the existence of water service to much of the area. Installation of municipal water for most homes in this area can be completed in approximately two to four years. This assumes these households provide an access agreement and complete any other activities required by the county in a timely manner. The schedule details are provided in Table 2. As Chemours continues to coordinate with the County, it plans to explore ways by which this timeline can be shortened. Conclusion Based on the foregoing analysis, Chemours has informed Parsons that it is prepared to proceed, subject to further discussions with Bladen County, with installation of municipal water to the 47 homes west of the Cape Fear River in Bladen County, even though the $73,400 per residence is substantially more than the cost to provide a GAC filtration system. Chemours is willing to install municipal water in this area, contingent on approximately 90 percent of the homeowners selecting municipal water, so that the implementation costs do not become cost prohibitive. 6.1.2 Bladen County East of Cape Fear River As shown on Figure 4, there are only four residences whose drinking water sampling results are at or above 140 ppt within this area. To provide service to Bladen County east of the Cape Fear River from existing sources, installation of an approximately 16,100 linear foot (LF), 6-inch water main would be required to bring water to the area from the existing water service on River Road (Figure 4). An existing groundwater well feeds this system and is assumed to be sufficient for the limited number of homes (four) at which the health advisory level has been exceeded. As an alternative, a water line could be extended from the existing Bladen County system west of the Cape Fear River. However, the length of the line, the need to acquire significant right-of-way, and the cost of drilling underneath the Cape Fear River make this option infeasible. Regardless, the long water main and limited number of customers would require that flushing hydrants be installed to maintain the water quality. The flushing hydrants would result in wasting significant amounts of water. The hydraulics and system capacity indicate that it would be extremely difficult to maintain appropriate water quality over this distance given the number of homes. Estimated Costs The construction of a new and long water main to carry water to the four homes in Bladen County east of the Cape Fear River, along with connecting the four homes, is estimated to cost $1,770,000 – approximately $442,500 per house. The cost details are FEASIBILITY STUDY REPORT FOR PUBLIC WATER SERVICES PROPOSED MUNICIPAL WATER EXPANSIONS BY LOCATION US:162910190v10 8 summarized in Table 1, and a detailed breakdown of the estimated costs is provided in Appendix C. Estimated Schedule Although there are only four homes in this area, the need to construct a new and long water main to reach these households would take considerable time. Therefore, installation of municipal water to these houses would take about the same time as is required for the west side of the river. As shown on Table 2, Parsons estimates that installation would take approximately two to four years. Conclusion It is not feasible, technically or in terms of cost and timeliness, to install municipal water east of the Cape Fear River in Bladen County. Given the distance to the nearest water mains and the lower density of homes, servicing these areas from the existing PWS will require long dead-end water mains that add significant cost to the system and may not provide a water supply of adequate quality. The combination of a long water main and so few houses means that it will be difficult, if not impossible, to maintain the quality of the water in the municipal system. Further, it would take approximately two to four years to install municipal water, at a cost of approximately $442,500 per house, which is not cost effective. The installation and operation of GAC filter systems at these households is cost effective, and the systems can be installed much more quickly. 6.2 Cumberland County As previously discussed, Cumberland County is currently evaluating the expansion of municipal water to residences in this portion of the county. Parsons used the current residential sampling data (samples collected through May 16, 2018) and the 2009 PER prepared by Cumberland County (Appendix B) to determine the size and location of water mains necessary to service homes in this area. As in Bladen County, Cumberland County’s feasibility study is focused on providing water and fire suppression services to all homes in this area. Chemours has committed to continue working with Cumberland County. 6.2.1 Cumberland County West of Cape Fear River In reviewing potential water sources for Cumberland County west of the Cape Fear River, it was determined that two water source options are available to provide municipal water to the 75 residences with water above 140 ppt threshold. This area could either be serviced by extending water from the Fayetteville PWC (Option 1), or water could be provided from the Bladen County groundwater system (Option 2). Each is described below:  Option 1 (Figure 5): Extension of water mains from Fayetteville PWC to the south. This option includes the installation of approximately 11,000 LF of 16-inch water main along Highway 87 from the nearest existing main (located on Highway 87 just south of U Tyson Road) to bring water to the service area.  Option 2 (Figure 6): Water provided from Bladen County groundwater system located south of the area. For this option, approximately 6,000 LF of 12-inch water main would be extended south into Bladen County to connect with the proposed water mains and new well proposed for providing service to the area FEASIBILITY STUDY REPORT FOR PUBLIC WATER SERVICES PROPOSED MUNICIPAL WATER EXPANSIONS BY LOCATION US:162910190v10 9 west of the Cape Fear River as described above. This shorter 12-inch line would be in lieu of the 11,000 LF of 16-inch water main required by Option 1. Estimated Costs The estimated cost of Option 1 (bringing water from Fayetteville PWC south to these 75 residences) is $15,730,000. This is approximately $209,700 per home. The estimated cost of Option 2 (obtaining water from Bladen County for these 75 residences) is $7,230,000. This is approximately $96,400 per home. The cost details are summarized in Table 1, and a detailed breakdown of the estimated costs is provided in Appendix C. Estimated Schedule As shown on Table 2, the schedule for installation of municipal water under Option 1 would be approximately six to 10 years. This is due to the extensive network of water mains that must be installed and the long main running down Highway 87 to service the area. Parsons estimates that the period for installation for Option 2 would be somewhat less given the shorter distance from the water source. As shown on Table 2, this option is estimated to take approximately five to eight years. Conclusion It is technically feasible to extend public water service to the homes in Cumberland County west of the Cape Fear River due to the density of homes combined with the availability of a nearby water source. However, it would take a considerable period of time (six to 10 years) to accomplish this, which raises serious concerns about the implementability of this option. Moreover, the cost per home under either option would appear to be significantly greater than $75,000. Because Cumberland County is already evaluating bringing municipal water to this area, it may be that if the County’s plans proceed sufficiently, the costs needed to implement connections for the homeowners with impacted wells will significantly decline and that such connections could become cost effective in the future. Chemours will continue to work cooperatively with the County to evaluate the feasibility and implementability of these connections. 6.2.2 Cumberland County East of Cape Fear River As shown on Figure 7, there are 35 residences whose drinking water sampling results are at or above 140 ppt within this area. To provide municipal water to these homes, a water main must be extended from Fayetteville PWC to the south. This service area would require extending a 31,500 LF, 12-inch main from the intersection of NC 210 and Cedar Creek Road (in addition to the smaller mains to service the homes). The long water main and limited number of customers may result in water quality issues within the service area. Parsons’s initial analysis indicates that appropriate water quality would be difficult to maintain, given the hydraulics and capacity of the system. As an alternative, a water line could be extended underneath the river from the proposed system west of the Cape Fear River. However, the length of the line, the need to acquire significant right-of-way, and the cost of drilling underneath the Cape Fear River make this option infeasible. Estimated Costs The estimated cost of providing municipal water to the 35 residences in Cumberland County east of the Cape Fear River, is $11,960,000. This is approximately $341,700 per FEASIBILITY STUDY REPORT FOR PUBLIC WATER SERVICES NEXT STEPS US:162910190v10 10 house. The main cost driver is the long distance from an existing public water source. The cost details are summarized in Table 1, and a detailed breakdown of the estimated costs is provided in Appendix C. Estimated Schedule Given the current lack of municipal water infrastructure, a new and long water main must be constructed to reach these 35 households. As shown on Table 2, Parsons estimates that such installation, as with the west side of the River, would take approximately five to eight years. Conclusion It is not feasible, technically or in terms of cost and timeliness, to install municipal water east of the Cape Fear River in Cumberland County. Given the existing lack of municipal water infrastructure, distance to the nearest water mains, and the lower density of homes, installing municipal water means that these residences will be on bottled water for years. Further, servicing these areas from the existing PWS will require long dead-end water mains that add significant cost to the system and may not provide a water supply of adequate quality. Further, it would take approximately five to eight years to install municipal water, at a cost of approximately $341,700 per home, which is not cost effective. The installation and operation of GAC filter systems at these households is cost effective, and the systems can be installed much more quickly. 7.0 NEXT STEPS Parsons recommends that Chemours continue to coordinate with both Bladen and Cumberland Counties to act in the most timely and cost-effective way. The path forward will depend significantly on the actions that the Counties take to expand their municipal water systems.

MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` Executive Summary 1 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 EXECUTIVE SUMMARY 1.0 General North Carolina counties are charged with the responsibility of providing for the health, safety and welfare of their citizens. Hence, the counties have created health departments, inspection departments, social programs and other agencies for the security of the public. Likewise, provision of safe drinking water and other utilities such as wastewater fall under these county responsibilities. This study, prepared by Marziano & McGougan, P.A. of Asheboro, North Carolina, in partnership with Koonce, Noble & Associates, Inc. of Lumberton, North Carolina, represents a continuing effort by the Cumberland County Board of Commissioners to determine the most feasible method of developing a county-wide water system to serve its citizens. The primary focus of potential water service is the rural areas located outside of the various Municipal Influence Areas (MIAs) and the Fort Bragg Military Base. The following articles in this executive summary describe the report findings relative to formation of a county-wide water system. This executive summary should be read with the idea in mind of reading the entire report in detail to develop a thorough understanding of the methodology used to develop recommendations. 2.0 Methodologies The following methodology was used in developing the recommendations contained in this report: 1. Analysis of existing population trends was performed. From that analysis standard techniques were used to develop population projections for a 20-year planning period. 2. The County areas lying outside of the MIAs were divided into sub-section areas based upon existing township and census tract areas. This allowed the sub- sections to be studied both from a social/economic and census perspective. For the purposes of this report, these sub-sections are referred to as “Districts.” 3. The population projections were used to develop water projections on a District basis. Water usage factors were applied to the area population along with allowances for commercial/industrial growth and unaccounted “lost” water to develop the final water demand projections for the planning period. 4. Existing water systems in the Cumberland County area and adjoining areas were researched to determine potential for providing potable water supply to the County regions. This analysis and discussion included existing municipal water systems that have a presence and are providing potable water to their specific customer base. The discussions further segregated the water supply availability between surface water systems and groundwater systems. A discussion on the available surface water and groundwater in Cumberland County follows in Section 5 of this report. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` Executive Summary 2 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 5. Once the water projections were determined along with a picture of the available water supply in Cumberland County, the Districts outlined in item 2 above were further analyzed to determine if there was sufficient population to support a central water system. From this analysis the areas were defined as described in item 2 above and the data reduced to a cost basis. Priorities were determined for each area based upon the cost per customer to develop the water system. 6. A county-wide water system is essentially made up of two major parts: a water supply source; and a water distribution system. Determination of the water distribution system is fairly simple in that it requires following existing rights of way to serve known locations of customers. The major decision making for the distribution system relates to proper sizing of water lines to transmit the required quantity of water through the system for the planning period. Determining a water supply source for a long-term supply is not quite as simple. This is because the water supply source must be available for the planning period and well beyond. 7. To develop a recommendation for the potable water supply to the County water system, alternatives were developed and analyzed. The alternatives in Section 6 of this report include the following alternatives: • “No Action” Alternative • Alternative #1: Developing a County-Owned Surface Water Supply • Alternative #2: Developing a County-Owned Groundwater Supply • Alternative #3: Negotiate a Purchase Contract with an Existing Provider o Alternative #3a: Public Works Commission of Fayetteville o Alternative #3b: Lower Cape Fear Water & Sewer Authority Each alternative was discussed based on its relative merits. A preliminary cost analysis was performed to determine the most cost-effective alternative with regard to water supply. The water distribution cost component of the analysis was kept the same for each alternative because it does not change appreciably for any of the supply alternatives analyzed. Finally, a comparison matrix was developed that compared various facets of each alternative from a social/economic, political and environmental standpoint. Each facet was given a point rating and the alternative with the lowest point rating (least adverse impact) was selected as the most feasible alternative for source water supply. 8. The engineers researched current financing alternatives available for funding a county-wide water system. Additionally, the engineer’s experience with other county water systems was used to recommend a long-term financing plan that should provide the best opportunity for Cumberland County to develop a county- wide water system on a district by district basis. 9. All the data contained in the items listed above was compiled and the engineers made recommendations based on their findings and opinions. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` Executive Summary 3 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 3.0 Findings This report found that a central water system could be developed on a district by district basis in Cumberland County. However, development of the water system would depend upon obtaining adequate financing once an area exhibited the proper population density in order to keep user charges at a feasible level. Several adequate water supplies are available to Cumberland County for providing potable water. The existing supplies preclude the necessity for Cumberland County developing their own County water supply system (surface or groundwater). Initially, the area of Cumberland County with the highest population density is located within the Southwest District. Because the Southwest District is relatively large and contains nearly 5,000 potential customers, the entire Southwest Water District cannot be served in a single project phase. Phase 1 has been identified as the area in the Southwest District with the highest number of customers per mile of road and the area with the greatest critical health need, specifically Southpoint. Other areas for consideration in the Southwest District include the high-density areas located within the Hope Mills MIA and the areas along the NC-87 corridor. SOUTHWEST (GRAYS CREEK) RURAL WATER DISTRICT DISTRICT-WIDE WATER SYSTEM COST SUMMARY Preferred Alternative = Alternative #3a Purchase Contract with PWC for 5 mgd Capacity 1. Southwest Water District $27,759,000 a. Interconnection Fees/Upgrades $3,400,000 b. Phase 1 (Southpoint area) $6,432,000 c. Remaining Areas Inside District $11,053,000 d. Areas Inside Hope Mills MIA $6,874,000 MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` Executive Summary 4 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 The decision to outsource the water supply will require solid thinking on the part of the elected officials of Cumberland County. Final selection of the water supply source will depend in part upon successful negotiation of a feasible contract arrangement with an outside entity. Long-term financing for rural water systems is available to Cumberland County. Grants are also available to Cumberland County for some of the proposed Districts because of their lower income levels. Any grant funds would lessen the end user cost as presented in this report. This report estimates that Phase 1 of the Southwest Water District could have a potential customer base of 1,500 connections and an average daily demand of 1.0 mgd for the first phase of water system construction. A potable water supply contract purchased from PWC (Alternative #3a) is considered the most economical method of water supply for Phase 1 of the Southwest District. The following assumptions are used to calculate the monthly water bill for a Phase 1 customer in the Southwest Water District: • Southwest District is constructed as first phase in rural water system • Cost for first phase of water transmission/distribution/storage is $6.4 million • Cost for initial capacity fees and interconnection requirements is $3.4 million • Zero grant contribution for each alternative (100% loan) • Full loan amount borrowed over 40-year term, 4.0% interest • Average daily water demand of 1.0 mgd • 1,500 water customers (100% connection rate) • Per 1,000 gallon rate for water supply established by PWC ($2.00 per 1,000) • Per 1,000 gallon rate for O&M service established by PWC ($0.50 per 1,000) MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` Executive Summary 5 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 CUMBERLAND COUNTY PUBLIC UTILITIES RURAL WATER FEASIBILITY STUDY ESTIMATED ANNUAL O&M COSTS AND MONTHLY WATER BILLS Alternative #3a - Purchase Contract with PWC for 5 mgd Capacity 1.

These recommendations are based upon the engineer’s best judgment obtained from experience with other similar systems in the region. The recommendations are only for consideration by the elected officials of Cumberland County and may be varied to suit the County’s social and/or political needs within reasonable guidelines. Specific recommendations in this report are as follows: • Develop a county-wide water system based upon the priorities shown in this report, beginning with the Southwest portion of the County. Set up this designated area as the Southwest Water and Sewer District. • Utilize the USDA-RD as the primary source of financing for the county owned water facilities. Utilize NCDENR-DWSRF and other state agencies as practical for additional/supplemental funding. • Utilize water supply from PWC as the primary source of supply if a mutually beneficial agreement can be reached. Meet with additional water purveyors such as Harnett County and the Lower Cape Fear Water and Sewer Authority for additional supply as warranted during negotiations. • Outsource the water system operation and maintenance with the chosen water purveyor if a mutually beneficial agreement can be reached. 5.0 Implementation A plan of action must be developed to generate the necessary contacts, contracts and other data required for financing, permitting, designing, operating and maintaining a county wide water system. A generalized list of the action items for implementation follows: 1. After review and acceptance of the findings in this report, begin preparations for developing a County owned water system in the proposed Southwest Water and Sewer District. Prepare necessary legal documents, hold public hearings and form the Southwest Water and Sewer District. Additionally, the other districts contained in this report can be formed at this time or at a later date as desired. 2. Set up meetings with USDA and NCDENR for the purposes of beginning applications for financing of the selected project. After meeting with USDA, determine the type of bonds to be implemented for project financing. 3. Set up meetings with PWC to begin negotiations for outsourcing of water supply. Additionally, continue discussions with Harnett County and the Lower Cape Fear Water and Sewer Authority to ascertain the feasibility of obtaining additional water supply. 4. Develop a detailed, Preliminary Engineering Report along with an Environmental Assessment for the Southwest Water and Sewer District water system. Submit the Preliminary Engineering Report along with application for federal assistance to USDA. Prepare additional applications for SRF and other agency funding as may be appropriate. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` Executive Summary 7 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 5. Approach citizens in the Southwest Water and Sewer District area to operate as a steering committee to assist in acquiring sign-ups for the use of the water system, provide public information to the potential water users in the District, and assist the County in moving forward with the development of the water system. 6. Depending upon the status of the applications for financing, begin preparations for obtaining bonds to pay the project cost. 7. When financing plans are complete and a sufficient number of sign-ups have been obtained to meet the financing requirements, obtain the services of a qualified engineering firm to develop plans and specifications for the proposed water system. The above items generally describe the important steps in implementing a County owned water system for the proposed Southwest Water and Sewer District. The exact order of the steps may vary from that shown above. Several official meetings to discuss the formulation of new policies will be necessary prior to disseminating any information to the public. The purpose of these policy meetings will be to provide the most current, accurate information to the Cumberland County Board of Commissioners. The timing of total project implementation for a single District can vary from as little as six months to over two years. 6.0 Engineer’s Comments First of all, the engineers at Marziano & McGougan, P.A. and Koonce Noble & Associates, Inc. wish to express their appreciation to Cumberland County staff and officials for having the opportunity to assist in the potential formation of a much needed county-wide water system. Our firms have worked on many county-wide water and sewer systems in North Carolina over the past 40 years and stand ready to assist officials of Cumberland County in any way possible as they endeavor to create a successful county-wide water system. The engineers feel that Cumberland County has substantial justification to develop a county- wide water system. Again, we must stress that sufficient customer density in project areas must be obtained before a system can feasibly support a water system from a financial standpoint. At this time, only one proposed water and sewer district meets these criteria. Even so, construction cost for the Southwest Water and Sewer District will generate significant user charges for the water customers. The engineers maintain that acquisition of grants to lower the user charges will be almost mandatory for feasible development of the Southwest Water and Sewer District. Our recommendations in the report body do not account for any grants. However, we can provide grant scenarios to Cumberland County in separate documents for feasibility comparison. Meetings with USDA-RD will assist in determining the actual grant eligibility for any of the Districts. The engineers have recommended the primary source of funding as the U.S. Department of Agriculture specifically because project financing can be spread over a 40 year period. Additionally, USDA can provide grants to the Southwest Water and Sewer District for up to 45% of the construction cost with a maximum not to exceed $2 million on a project by project basis. Additional grants may be available if significant potential for public health issues can be mitigated by construction of a central water system. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` Executive Summary 8 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 Also, innovative financing techniques such as special assessments, low interest loans and other means can be utilized along with the USDA financing to further reduce debt service costs. Some of the difficult decisions to be made by the elected officials include: • Requiring mandatory sign up for the water system; or in the lieu of that, developing a "dry tap fee” wherein a potential customer that does not sign up for water service will have to pay their share of the debt service cost. • Determining whether or not the County is willing to provide budgeted financing from county funds to reduce user charges until such time as additional customers are created to the point where the system can pay back the funds provided by the County. • Developing a "view to the future" attitude that will enhance County officials’ long-term decision making. The engineers also feel that Cumberland County has developed a sufficient track record with PWC and other water purveyors in the area that qualifies them to make the difficult decisions necessary to develop a county-wide water system. The problems that exist today that have led to the necessity to prepare this study, along with other studies in the past, will not go away. History has shown that as areas become more densely populated, central water and sewer utilities become more mandated. The burden for provision of these facilities in the case of Cumberland County falls upon the County’s shoulders. Development of a well designed, feasible water system will help safeguard the public health, safety and welfare well into the future. Other ordinances regulating locations of septic tanks and/or extension of nearby sewer lines will also assist in protection of the public. Finally, the engineers feel that they have provided sufficient physical data for the formation of water and sewer districts to allow county officials to determine the feasibility and potential performance of a water system. The data is prepared in such a manner that it may be easily updated and/or slight changes made in the districts to allow for "what if" analysis scenarios. We urge the County officials to read the document carefully in its entirety and ask any questions of us that may arise. We will provide answers in a timely manner. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 1 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 PRELIMINARY ENGINEERING REPORT 1.0 Introduction The purpose of this Preliminary Engineering Report (PER) is to provide a water service plan for rural areas of Cumberland County, North Carolina. The primary focus of potential water service is the rural area located outside of the various Municipal Influence Areas (MIAs) and the Fort Bragg Military Base. This focus isolates a crescent-shaped area that extends from the Spring Lake MIA in the north, eastward to the Sampson County boundary, southward to the Bladen County Boundary, and westward to the Hope Mills MIA, excluding the urban areas surrounding Fayetteville and Fort Bragg. Marziano & McGougan, P.A. of Asheboro, North Carolina, partnered with Koonce, Noble & Associates, Inc. of Lumberton, North Carolina, have been contracted by Cumberland County to develop this PER and make formal recommendations regarding the “no action” alternative, the potential development of water supply sources available to the County, and the potential negotiation of water purchase contracts with other entities. Once completed, Cumberland County officials should review this PER to determine if any additions/revisions will be necessary to augment or reorganize any of the recommendations contained herein. This PER will address the following issues related to the development of viable rural water service in Cumberland County: • Discuss the existing water systems and water supply resources relevant to the potential water service areas • Delineate potential water service areas with accepted boundaries that can be interpreted easily by potential funding agencies; these potential water service areas will be referred to as Districts in this PER • Assess the water demand needs of each District • Evaluate the “no action” alternative • Analyze any alternatives that will lead to a feasible plan of water service for each District • Recommend water supply actions on a District-specific level • Ready the County to apply for funding from various organizations, public and private, such as USDA Rural Development Administration 1.1 Project Need A centralized, sealed, public water system serves two primary purposes: the provision of safe drinking water to customers, and water quality/quantity monitoring for the management of the resource. Koonce Noble & Associates and Marziano & McGougan have investigated the potential solutions for providing a public water supply to Cumberland County residents in rural areas. These rural residents utilize an at-risk resource that may not be adequate to fulfill the long term needs of the County and its residents. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 2 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 Considering the projected population increase, BRAC actions, and the potential water resources available to Cumberland County (purchased water, groundwater, and surface water), it is evident that a sustainable water supply resource is both needed and available to support the incoming population to rural areas of the County. Although continued use of private wells is an option, it is the opinion of Koonce Noble & Associates and Marziano & McGougan that Cumberland County needs to secure a water supply resource immediately for its residents if the County intends to construct a viable, rural county-wide project in the future. At the present time, there is no centralized form of water supply for the majority of southern and eastern Cumberland County. Only the relatively small areas within and adjacent to the municipal limits of Godwin, Falcon, Wade, Eastover, and Stedman are served with a public water supply. The remainder of the rural County areas, approximately 242 square miles excluding the MIAs, are forced to obtain their water from private wells ranging from 50-ft to 200-ft in depth. Most of the private wells obtain water from the shallowest aquifer available, the surficial aquifer. The average depth of the surficial water table in the area is 20-30 feet. Many of the wells in the County lack the necessary filter capabilities to ensure adequate water quality. Therefore, the water extracted from such wells has higher concentrations of sulfates, organics, iron, and other impurities and are more susceptible to pollution and contamination. With the predominant land use in rural areas being agriculture, the consistent use of pesticides and fertilizers will only serve to deteriorate the quality of the groundwater above a certain depth before the natural filtration of the soil can have an effect. The soil is also naturally acidic, and the water extracted generally has an acidic pH in the range of 6.0-6.5. In the Southpoint community, located within the Grays Creek Township, a petroleum contamination plume from leaking underground storage tanks has reached private wells and raised significant concerns over the safety and quality of groundwater in this region. Additionally, there is only a limited service area with centralized wastewater collection for the majority of southern and eastern Cumberland County. The exception is the Town of Stedman and the North Cumberland Regional Sewer System (NORCRESS) which serves the municipalities of Godwin, Falcon, Wade, and Eastover; consequently, these areas are served with a public water supply to minimize the risk of pollution to individual wells within proximity to the public sewer system. The vast majority of County residents treat their sewage with septic tanks and on-site nitrification trenches. Even the newest septic tanks in good condition can be installed within close proximity to private wells. There are also an undocumented number of septic tank systems that are failing and rely on the natural in-situ soils for their treatment capabilities. These failing septic systems are the prime suspect for the higher concentrations of organics and sulfates in the extracted well water.

The BRAC Regional Task Force (RTF) Final Comprehensive Regional Growth Plan provides an assessment of the impact to population and infrastructure in the counties surrounding Fort Bragg and Pope Air Force Base due to the military’s BRAC program. This Regional Growth Plan is the tool that assists local communities in the assessment, planning and preparation for the impacts of BRAC actions at Fort Bragg and Pope AFB. An estimated 8,700 military-related personnel are expected to relocate to the region by 2013; the local population is surrounding counties is expected to increase by an estimated 40,000 by the year 2013. The BRAC RTF Final Comprehensive Regional Growth Plan provides detailed assessments of the following effects within Cumberland County, as well as the surrounding region: military investments in the region, normal population growth, expected population growth, economic impacts, housing, education, workforce development, transportation, water/sewer utilities, information technology, public safety, health care, etc. These issues, along with recommended actions, are detailed in the Regional Growth Plan and clearly indicate the need for immediate infrastructure planning and construction to support this large influx of people.

It is the engineer’s opinion that this data does not account for the entirety of the scope of the BRAC commission’s recent recommendations for troop realignments to Fort Bragg and Pope AFB. Although some of the additional growth from the BRAC program is accounted for in the State’s published projections, the recent developments between Fort Bragg and its regional utility partners has poised the region centered about Fort Bragg and Cumberland County for intensive growth that could be above current projections. A description of the BRAC commission’s report is located in the following sections and details the nature and scope of the surge in population expected in the vicinity of Fort Bragg. See Appendix B for more specific estimates of the population projections for rural Cumberland County. Table 1 – Historic Population and Future Projections for Cumberland County (published data from NCOSPL) Cumberland County Year Total Population Increase % Growth 1970 212,042 - - 1980 247,160 35,118 16.56% 1990 274,713 27,553 11.15% 2000 303,060 28,347 10.32% 2007 313,616 10,556 3.48% 2009 315,955 2,339 0.75% 2014 324,140 8,185 2.59% 2019 332,006 7,866 2.43% 2024 339,397 7,391 2.23% 2029 345,757 6,360 1.87% Total Growth - 29,802 9.43% MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 5 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 2.2 Population Projections M&M/KNA has performed a detailed examination of the historic population data for Cumberland County. Using the population records from the 1970 U.S. Census through the 2007 NCOSPL county estimates, future population projection models have been developed in an effort to give Cumberland County officials multiple growth scenarios that will suit the County’s future infrastructure planning needs. These population projection methods are as follows: published data available from the NCOSPL, linear regression (straight line) model using 1970 through 2007 population data, and 2nd order polynomial (parabolic) model using 1970 through 2007 population data. From these three projection models, the 2nd order polynomial model projects the lowest population for Cumberland County in the year 2029 (341,586 persons), NCOSPL published data projects the next greatest population in the year 2029 (345,757 persons), and linear regression projects the highest population in the year 2029 (379,920 persons). The following table summarizes these population projection findings. Graphical representations of these modeling techniques, as well as a chart comparison of the total population projection models, can be found in Appendix B. For the purposes of this report, the linear regression model is considered the best model to project the future populations and water demands in Cumberland County with an overall growth rate of 17.09% over 20 years. The linear regression model provides the highest population projection that takes into account localized growth and economic stimulation factors driven by Fort Bragg’s expansion and other local economic factors such as the I-295 corridor, etc. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 6 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 Table 2 - Total Population Projection Methodologies for Cumberland County Population 2nd Order Polynomial Published NCOSPL Data Linear Regression Year Total Population Increase per Year % Growth Total Population Increase per Year % Growth Total Population Increase per Year % Growth 1970 212,042 - - 212,042 - - 212,042 - - 1980 247,160 35,118 16.56% 247,160 35,118 16.56% 247,160 35,118 16.56% 1990 274,713 27,553 11.15% 274,713 27,553 11.15% 274,713 27,553 11.15% 2000 303,060 28,347 10.32% 303,060 28,347 10.32% 303,060 28,347 10.32% 2007 313,616 10,556 3.48% 313,616 10,556 3.48% 313,616 10,556 3.48% 2009 318,160 4,544 1.45% 315,955 2,339 0.75% 324,464 10,848 3.46% 2014 325,990 7,829 2.46% 324,140 8,185 2.59% 338,328 13,864 4.27% 2019 332,504 6,514 2.00% 332,006 7,866 2.43% 352,192 13,864 4.10% 2024 337,702 5,199 1.56% 339,397 7,391 2.23% 366,056 13,864 3.94% 2029 341,586 3,883 1.15% 345,757 6,360 1.87% 379,920 13,864 3.79% Total 20- Year Growth - 23,425 7.36% - 29,802 9.43% - 55,456 17.09% 2.3 Population Projections for Rural Areas In order to accurately project the 20-year population increase for rural areas of Cumberland County, the rural areas must be isolated from the entire County projections by making a simple assumption about the municipal growth in Cumberland County. The rural population is assumed to be the difference between the total county population and the municipal estimates as calculated by NCOSPL. Unfortunately, no official governmental entity maintains municipal projections beyond two years into the future due to the higher volatility of these population growth rates (due to annexation, local employment, geography, etc.). M&M/KNA has adopted the percent growth rate from the NCOSPL growth model for future municipal population projections in Cumberland County. In this assumption, municipal populations will continue to grow at the same percent growth rate over 20 years that NCOSPL published for the entire County. The overall growth rate of 9.43% over 20 years is assigned to the municipalities within Cumberland County. This translates to a municipal population projection of 231,793 persons in the year 2029. Additionally, this assumption allows some degree of “correction” for the surge in municipal population experienced when Fayetteville annexed westward to the County boundary in 2005. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 7 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 In 2009, the estimate population living in rural (unincorporated) areas of Cumberland County was 112,650 persons. In 2029, the difference between total County population and municipal population is estimated to be 148,127 persons, an overall growth rate of 31.49% over 20 years and an increase of 35,477 persons moving into rural Cumberland County. The following table summarizes these population projection findings. Graphical representations of these modeling techniques, as well as a chart comparison of the total population projection models, can be found in Appendix B.

The following assumptions are made for these water demand projections: • Residential water demand = 175 gpd per customer • Commercial/Industrial reserve water demand = 20% of residential demand • Water loss in the system = 10% of total water demand • Peak Day Water Demand Factor = 1.5 (constant for the planning period) • Potential customers that are located within MIAs (i.e. Hope Mills, Stedman, etc.) can be served by the new Water Districts • Assume 85% connection rate to the water system in each District (and MIAs) • Assume customer base will grow at a rate equal to rural Cumberland County (31.49% over 20 years) • Beginning in 2010, a new Water District will be constructed every three years, constructed in the following order of priority: o Southwest o Linden o East Central o Southeast o Northeast Average daily water demand in 2010 (Year 1) is estimated to be 1.1 mgd (peak demand of 1.7 mgd) after the construction of the Southwest Water District. After the construction of all proposed Districts, Average daily water demand in 2029 (Year 20) is estimated to be 3.2 mgd (peak demand of 4.8 mgd), a 190% increase from the initial year’s average daily water demand. This large increase is due to the construction of five (5) rural Water Districts within the planning period. This translates to a projected customer base of 13,726 water customers (85% connection rate) with a service population of 36,375 persons. The following table summarizes these water demand projections, see Appendix B.

The intent of this discussion is to provide information to determine the capacity, current sales partnerships, and water supply resources available to proposed service areas within Cumberland County. 3.1 Surface Water Systems 3.1.1 Fayetteville PWC The Fayetteville Public Works Commission's (PWC) water system serves all areas within the City limits of Fayetteville and other developed areas outside the City limits. PWC provides retail service to residential, commercial, industrial and governmental customers. In 1998, PWC merged with the Town of Hope Mills to consolidate water services in the region. The Fayetteville PWC water system provides service to the City of Fayetteville, Hope Mills, Spring Lake, Fort Bragg, Eastover, Stedman, and portions of eastern Hoke County. In 2008, there were approximately 78,000 active water customers with a total service population of approximately 185,000 residents. Average daily water use is estimated to be 24.1 mgd with maximum daily water use estimated to be 42.3 mgd. The system is comprised of 1,284 miles of water mains and 13 storage tanks with an effective storage capacity of 36.1 mgd. Fayetteville PWC treats potable water at two separate facilities. The Glenville Lake WTP was originally constructed in 1942 and has a current treatment capacity of 18 mgd. Glenville Lake WTP receives raw water supplied from an intake on Glenville Lake as well as transfer capability from the Cape Fear River and Cross Creek. A 36” raw water transmission main from the Cape Fear River to Glenville Lake WTP allows the transfer of additional raw water to this facility for treatment during periods of high demand within the water system. In 2003, this facility switched from chlorine disinfection to chloramination disinfection in order to reduce the amount of disinfection byproducts in the finished water. In 2008, this facility had an average daily production of 8.4 mgd. The P.O. Hoffer WTP was originally constructed in 1969 and has a current treatment capacity of 39.5 mgd. Identical to the Glenville Lake WTP, in 2003 the P.O. Hoffer WTP switched from chlorine disinfection to chloramination disinfection in order to reduce the amount of disinfection byproducts in the finished water. P.O. Hoffer WTP receives raw water exclusively from the Cape Fear River. In 2008, this facility had an average daily production of 16.9 mgd. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 11 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 3.1.2 Eastover Sanitary District The Eastover Sanitary District (ESD) is a USDA Rural Development Water District located east of the Cape Fear River and encompasses the Town of Eastover and portions of the I-95 corridor. The Town of Eastover was incorporated on July 26, 2007, after the formulation and implementation of ESD Phase 1. ESD Phase 1 began operation in 2004 and is supplied by the PWC water system. ESD Phase 1 serves approximately 3,600 persons and purchases approximately 0.30 mgd from PWC. ESD Phase 1 was constructed of approximately 50 miles of 2-inch through 16- inch water mains that were funded primarily through USDA monies. This project was a success through the high percentage of residents that initially signed up for water service. ESD currently serves approximately 90 to 95% of the residences located within the Phase 1 service area. The elevated tank on Clinton Road (NC-24) and the elevated tank on Eastern Boulevard (near the intersection of NC-87 and I-95 Business) serve ESD Phase 1. These tanks are located within the low pressure zone of the PWC water system. No master meters exist between ESD Phase 1 and PWC. All ESD customers are metered individually and billed by PWC. The current agreement between ESD and PWC requires that all water system supply, operation, maintenance, meter reading, billing, and other accounting services will be handled through the PWC Operations Center in Fayetteville. ESD does not have a department of public works or any hired personnel to oversee the daily operations of the water system. ESD owns the Phase 1 water system, the customer base which it serves, and the bonded debt attributed to the water system. A second ESD phase is in the final design phase and has received funding commitments from USDA Rural Development. It is intended that ESD Phase 2 continue the water service and O&M relationship with PWC due the financial economy that PWC provides to district customers. 3.1.3 Town of Hope Mills As previously discussed, the Town of Hope Mills merged all water and sewer utility services with PWC in 1998. Hope Mills is an extension of the PWC system and all utility assets within the Town are part of the PWC utility system. This merger was a positive step for the residents of Hope Mills because of the financial benefit of joining with a larger utility. In the decision to merge with PWC, it was shown that PWC was capable of providing identical utility services at a lower cost to the user. As of 2007, Hope Mills had a population of approximately 12,843 residents. 3.1.4 Town of Stedman In the past, the Town of Stedman operated several wells that served as the sole supply to residents. In 2004, Stedman entered into an agreement with PWC to supply and maintain the water system; Stedman owns the water utility assets within its jurisdiction. PWC installed a 12-inch water transmission main from the eastern perimeter of the distribution system and extended along NC-24 to MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 12 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 the Stedman water system. This transmission main now serves the 806 residents of Stedman. 3.1.5 Town of Spring Lake The Town of Spring Lake water system serves all areas within the town limits. The Spring Lake water system has approximately 2,800 residential, commercial and industrial water connections that serve a total population of approximately 9,000 residents. The Town of Spring Lake owns, maintains, and administers its water distribution system in its entirety, approximately 96 miles of pipeline. Spring Lake is supplied exclusively through purchased water connections with PWC and Harnett County. 3.1.6 Fort Bragg Currently, Fort Bragg operates an 8.0 mgd water treatment facility that obtains its raw water from the Lower Little River in northwest Cumberland County. In 2007, American States Utility Services, Inc. of Costa Mesa, California purchased the water and wastewater facilities of Fort Bragg and Pope AFB. This privatization action consolidates the water and wastewater utilities (treatment and distribution systems) at Fort Bragg and Pope AFB under singular ownership. Under the performance agreement with the new owners, the existing Fort Bragg WTP will continue to operate until 2009-2010 when PWC and Harnett County construct water transmission mains to the Fort Bragg WTP site. The purpose of these large transmission mains will be to decommission the Fort Bragg WTP and allow the Fort Bragg water distribution network to be supplied by two primary suppliers: PWC and Harnett County. The contract between the Department of Defense, the new utility owner, PWC, and Harnett County allows for equal water supplies to be purchased from each supplier on alternating days. In the event of an emergency at either supplier, the other supplier will be capable of transferring the maximum daily water demand to Fort Bragg via the newly constructed transmission mains. As a condition of the transfer of utility assets from military ownership to privatization, American States Utility Services, Inc. must maintain the Fort Bragg water distribution system in compliance through the following measures: satisfactory operation and maintenance of the water distribution system, capital water loss reduction program, water main replacements and/or rehabilitations, routine water main inspection, as well as storage tank and pump station maintenance and upgrades. 3.1.7 Town of Falcon The Town of Falcon water system serves all areas within the town limits as well as rural roads on the perimeter of town. The Falcon water system serves approximately 319 residents, approximately 250 customers. Falcon owns, maintains, and administers its water distribution system and is supplied exclusively through purchased water from the City of Dunn. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 13 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 3.1.8 Town of Godwin The Town of Godwin water system serves all areas within the town limits as well as rural roads on the perimeter of town. The Godwin water system serves approximately 121 residents, approximately 100 customers. Godwin owns, maintains, and administers its water distribution system and is supplied exclusively through purchased water from the Town of Falcon. 3.1.9 Linden Water & Sewer District The Linden Water & Sewer District was formed in February of 2003 by the Cumberland County Board of Commissioners. At present, this relatively new District has limited water infrastructure located within the town limits of Linden along with distribution mains along US-401 and NC-217. The Town of Linden, population of 142 persons, owns and operates the existing distribution system separate from the Linden Water & Sewer District. All water is supplied to the District by Harnett County Public Utilities. Water is currently supplied to this system from an elevated tank (South Central Tank #3) located along Elliott Farm Road. Currently, there are no existing sewer collection or treatment facilities in the District; all domestic wastewater is treated through individual septic tanks. Currently, Linden Water & Sewer District is in the final planning stages to begin construction of Phase 1A: approximately 10 miles of water distribution mains to serve approximately 200 rural customers located within the District. This project is considered a stepping stone for the construction of rural water service in northern Cumberland County. According to the preliminary engineering report prepared for this project, water purchased from Harnett County Department of Public Utilities is the most economically beneficial to the customers located in this District due to the presence of water supply mains from the Harnett County water system. Phase 1A of the Linden Water & Sewer District is expected to begin construction in 2010 and be operational in 2011. 3.1.10 Harnett County Public Utilities The Harnett County WTP area is supplied exclusively from the run-of-river intake located on the Cape Fear River in Lillington approximately 1,000 feet upstream of the US-401 Bridge. Harnett County provides potable water to all of the incorporated municipalities in Harnett County with the exception of the City of Dunn. Outside of the municipal limits, Harnett County’s water system extends throughout virtually all of the public roads in Harnett County with approximately 98% of available roads served with potable water. Similar to Fayetteville PWC, in 2003 this facility switched from chlorine disinfection to chloramination disinfection in order to reduce the amount of disinfection byproducts in the finished water. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 14 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 Outside of Harnett County, other areas that are served with potable water produced from the Harnett County WTP include the Towns of Fuquay-Varina and Holly Springs in southern Wake County, portions of western Johnston County, portions of eastern Moore County, portions of eastern Lee County, and portions of northern Cumberland County (Northern Franchise Area) including the Town of Linden (via the Linden Water & Sewer District). The Northern Franchise Area is located within the Spring Lake MIA and serves approximately 1,500 water customers in the residential developments along the US-401 Corridor, Elliott Bridge Road and Elliott Farm Road. In 2008, there were approximately 30,000 active water customers with a total service population of approximately 60,000 residents. Average daily water use is estimated to be 13 mgd with maximum daily water use estimated to be 18 mgd. The system is comprised of over 1,500 miles of water mains and 23 storage tanks. By the end of 2009, Harnett County WTP will be upgraded to a capacity of 24 mgd and Harnett County will begin to serve the Fort Bragg Military Base. With the ongoing construction to increase the Harnett County WTP’s capacity to 24 mgd, critical treatment components are designed to treat up to 36 mgd. This has been planned due to the fact that increased water sales to Holly Springs, Johnston County, and other partners in the surrounding region are experiencing significant growth and water demand is expected to increase substantially. Harnett County WTP’s upgrade to 36 mgd is expected to be operational in 2011. 3.1.11 City of Dunn The City of Dunn owns and operates the 8.0 mgd Archie Uzzle WTP that obtains raw water from the Cape Fear River. The Dunn water system serves approximately 4,600 residential, commercial and industrial water connections with a total service population of approximately 10,088 residents. Average daily water use is estimated to be 4 mgd with maximum daily water use estimated to be 6 mgd. The City of Dunn owns, maintains, and administers its water distribution system in its entirety, approximately 85 miles of pipeline. Currently, Dunn sells water to the Town of Falcon, Town of Benson, Sampson County, and portions of the Southeast Harnett County Water District. 3.1.12 City of Lumberton The City of Lumberton owns and operates the 16 mgd Lumberton WTP that obtains raw water from the Lumber River. Also, the Lumberton WTP obtains raw water from several wells located near the Lumber River with yields that are influenced by the nearby presence of surface water. The Lumberton water system serves approximately 10,000 residential, commercial and industrial water connections with a total service population of approximately 22,929 residents. Average daily water use is estimated to be 5 mgd with maximum daily water use estimated to be 8 mgd. The City of Lumberton owns, maintains, and administers its water distribution system in its entirety, approximately 225 miles of pipeline. Currently, Lumberton sells water to a small portion of the Robeson County water system. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 15 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 3.1.13 Lower Cape Fear Water & Sewer Authority In 1972, Bladen County, Brunswick County, Columbus County, New Hanover County, Pender County, and the City of Wilmington formed the Lower Cape Fear Water & Sewer Authority (LCFWASA) in order to assess regional water needs within the service area of the region served by these entities. LCFWASA is a non-profit public agency that owns and operates the raw water intake, pumping station and transmission pipeline systems that transfer up to 45 mgd to the Brunswick County owned Northwest WTP and the City of Wilmington owned Sweeney WTP. The Authority also provides service to industry located on US Highway 421 in the County of New Hanover. The LCFWASA intake is located on the Cape Fear River behind Lock and Dam #1 in Bladen County (King’s Bluff). This is the closest source of salt free surface water to coastal Southeastern North Carolina. Currently, LCFWASA is in the final planning stages to begin construction of a new raw water intake, pumping station and treatment facilities at the Bladen Bluffs site located near Tarheel in Bladen County. The new Bladen Bluffs Regional WTP is a cooperative effort among LCFWASA, NC Environmental Management Commission, NC Division of Water Resources, and the Lumber River Council of Governments to shift current groundwater users to surface water resources, thereby reducing the current groundwater consumption in the Central Coastal Plain Capacity Use Area (CCPCUA). The ultimate goals of this new facility are to provide sustainable surface water supply and regional aquifer conservation among the participants in the facility. Initially, the primary user of the Bladen Bluffs Regional WTP will be Smithfield Foods Packaging Company. Smithfield Foods is one of the largest employers in the region, with approximately 5,000 employees at its Tarheel facility. The Bladen Bluffs Regional WTP will have an initial treatment capacity of 4 mgd with an intake pumping capacity up to 30 mgd. The Bladen Bluffs Regional WTP is expected to be operational by the end of 2012. 3.2 Groundwater Systems 3.2.1 Town of Wade The Town of Wade is the only groundwater system in eastern Cumberland County. It supplies its 450 residents through the use of three groundwater wells in the Upper Cape Fear Aquifer, ranging in depth from 35’ to 50’. A 75,000 gallon elevated storage tank pressurizes the Wade water system. Average daily demand is approximately 0.035 mgd with peak day demand approximately 0.045 mgd. The combined safe yield of the three active wells is estimated to be 0.194 mgd. This is considered extremely high for wells in this region. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 16 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 3.2.2 Hoke County The Hoke County Regional Water System consists of 16 wells, eight well treatment facilities with a total capacity of 2.19 mgd based on 12 hours of pumping per day, eight elevated water storage tanks, and approximately 11,000 service connections. The system also receives water from the McCain Prison and from Fayetteville PWC through two booster pump stations. The total capacity available from PWC is 1.83 mgd, and the available capacity from McCain is 0.10 mgd. Therefore, the total water available is 4.12 mgd. In 2007, the average water produced and purchased was 1.90 mgd and the maximum daily production and purchase was 2.65 mgd. Hoke County has begun the installation of test wells for a USDA funded Phase V project. Phase V of the Hoke Regional Water System will install 14 wells and five well treatment facilities with a total capacity of 1.37 mgd based on 12 hours of pumping per day. This will bring the total system capacity to 5.49 mgd. 3.2.3 Robeson County The Robeson County water system currently consists of approximately 1,720 miles of water mains, 23,500 metered connections, 17 elevated water storage tanks, one ground storage tank, 14 well water treatment facilities and 31 production wells. Total storage including the ground storage is 7.85 million gallons. There are two elevated storage tanks and three wells under construction. Additionally, one well treatment facility is under design and production wells have been proposed for funding. If Robeson County were to serve the project area, the water would be primarily produced by the Parkton, St. Pauls East, and Rocco Well Treatment Facilities depending on varying hydraulic conditions. Additional water storage would be provided by the Shaw Mill Elevated Water Storage Tanks and a proposed 200,000 gallon in the Greensprings area. The Lumber Bridge facility could also possibly provide water, however the water from this facility is already obligated to Mountaire Farms and other existing demands. The Parkton Facility is located on US 301 East of Parkton and consists of a well, well pump, aeration basin, two high service pumps, chemical feed system (fluoride, caustic, polyphosphate and chlorination), two pressure filters, and a 100,000 gallon elevated water storage tank The St. Pauls Facility is located on NC 20 on the East side of St. Pauls and consists of a well, well pump, aeration basin, two high service pumps, chemical feed system (fluoride, caustic, polyphosphate and chlorination), two pressure filters, and a 200,000 gallon elevated water storage tank. The Rocco Facility is located on NC 20 East of the St. Pauls Facility and across from the Prestage Turkey Plant. This facility consists of four wells, chemical feed system (fluoride, caustic, polyphosphate and chlorination), two high service pumps, a 2 mgd concrete treatment structure, infiltration backwash lagoon, a 750,000 gallon ground storage tank and a 500,000 gallon elevated MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 17 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 storage tank. The concrete treatment structure consists of an aeration basin, a gravity filter with four cells, and a clearwell. The Shaw Mill elevated storage tank is a 500,000-gallon tank located off of Balance Farm Road approximately 2,500 feet north of Shaw Mill Road. There are several locations Cumberland County could connect to the Robeson distribution system. One point currently proposed as a possible connection to serve the Southpoint Subdivision is two existing 8” diameter water mains that connect at the intersection of Parkton Tobemory Road and Balance Farm Road. Static pressures were recorded at this location from July 3, 2008 through July 13, 2008 and from 45 to 70 psi. Robeson County also has an 8- inch water main that currently extends into Cumberland County on Roslin Farm Road. On the West side of I-95, there is an existing 6-inch water main on Leeper/Parkton Road. 3.2.4 Sampson County The Sampson County water system consists of District 1 and District 2. Current projects underway include District 2, Phase 3 and Phase 4. All districts are governed by the Sampson County Board of Commissioners sitting as the Sampson County Water District Board of Directors. Sampson County is in the process of installing four potable water wells to supply its growing customer base and has expressed interest in selling water to inter-local communities. Currently, Sampson County District 1 purchases all water from the following source providers: Autryville, Clinton, Roseboro, and Turkey. Total water purchase contracts are estimated to be 0.370 mgd. District 1 has approximately 1,200 water customers and an average daily demand of 0.150 mgd. Currently, Sampson County District 2 purchases all water from the following source providers: Clinton, Dunn, and Garland. Total water purchase contracts are estimated to be 1.120 mgd. District 2 has approximately 1,500 water customers and an average daily demand of 0.175 mgd. 3.2.5 Bladen County The Bladen County water system is divided into two districts: East Bladen and West Bladen. The East Bladen District is located to the east of the Cape Fear River and the West Bladen District is located to the west of the Cape Fear River. Based on the 2007 Water Supply Plan, East Bladen has approximately 60 miles of water mains consisting primarily in size of 6-inch to 12-inch diameter. There are 796 residential connections and five commercial connections. This district is served by two wells with a total capacity of 0.271 mgd based on 12 hours of pumping per day. Projected demand for the year 2010 is 0.193 mgd. Based on the 2007 Water Supply Plan, West Bladen has 260 miles of water main ranging primarily in size from 6 inch to 12 inch diameter. There are 3,959 residential connections and 5 commercial connections. The district is served by three wells with a total capacity of 0.799 mgd based on 12 hours of pumping MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 18 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 per day. Additionally, the West District also purchased an average of 0.185 mgd from Elizabethtown in 2007. Projected demand for 2010 is 0.210 mgd. The Lumber River Council of Government completed a Comprehensive Groundwater Study and Assessment that estimated that the aquifers had the following capacities in Bladen County: • Peedee Aquifer 2.70 mgd • Black Creek Aquifer 4.10 mgd • Upper Cape Fear Aquifer 1.23 mgd • Lower Cape Fear Aquifer 0.73 mgd • Total Safe Yield from Groundwater Sources 8.76 mgd 3.2.6 Private Water Systems Numerous private groundwater systems are located throughout rural Cumberland County and serve a wide range of residential customers including mobile home communities, multi-family developments, and single–family developments. For systems serving more than 15 connections, these systems are considered to be “community” systems. Minimum design standards of community water systems are mandated by NCDENR-Public Water Supply. The vast majority of private, residential water systems were designed with the minimum capacity (i.e. pipe sizes, well diameter, pumping capability, etc.) required to serve the anticipated number of homes within their respective development. This was to keep the up-front costs of the development as low as possible and resulted in small-scale water systems with virtually zero reserve capacity for growth in adjacent areas. Therefore, private, community water systems do not have a sphere of influence that can be extended for significant distances outside of the residential development. The focus of this study is to enable Cumberland County to secure a reliable, long-term source of water supply to provide rural water service to a phased county-wide rural water system. It would be extremely difficult and costly for the County to attempt to secure the use of private groundwater supply systems to supply the quantity of water needed to serve its long-term vision of a large water system with a broad customer base. Additionally, the assets under the control of various homeowner’s associations and private water operators have been in service for years and are at risk to the inherent liabilities that aging water systems develop over time. Cumberland County could attempt to acquire private water systems in an effort to boost the customer base of the overall rural system. However, depending upon the operation and maintenance of the private system, Cumberland County could assume private water systems laden with problems that range from well- known and documented failures, to issues that have gone unreported, unknown, and/or unaddressed for many years. This significant risk would come with marginal benefit for potential source water supply and additional customers to the overall system. In general, the relatively small scale and the risk of pre-existing conditions preclude private water systems from consideration as a long-term source of raw water supply. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 19 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 4.0 Proposed Rural Water Districts Delineating a potential service area boundary is one of the first priorities that Cumberland County faces in its evaluation of rural water feasibility. Due to the presence of numerous municipalities and other entities located within Cumberland County, any proposed boundaries must be accepted along jurisdictional, political, and environmental fronts. The potential water service areas identified in this report will be referred to as Districts. 4.1 Southwest Water District The proposed Southwest District is located in the extreme southwestern portion of Cumberland County within the Grays Creek and Rockfish Townships. The eastern boundary of the District borders the Cape Fear River, the southern boundary of the District borders Bladen County, and the western boundary of the District borders Robeson County. The northern boundary is generally defined as the limits of the PWC water service area (NC-87 to Bullard Road to Braxton Road). The proposed District boundary can be seen on the maps provided in Appendix A. The Southwest District is considered a top priority given the higher density of customers located within this part of the County, as well as the ongoing groundwater pollution concerns in the Southpoint Community. The following summarizes the critical attributes of this proposed Water District: • Total Service Area = 46.5 square miles, 5,812 existing homes • Total Service Area includes 10.0 square miles within the Hope Mills MIA • Total Service Area includes 2,470 existing homes within the Hope Mills MIA • 85% Connection Rate = 4,940 projected water customers • 117 miles of water pipeline to serve this customer base (estimated NCDOT roads only) • 42 customers per mile of NCDOT roads • Start-Up Year 2010: Projected Water Demand = 1.141 mgd, avg. day; 1.711 mgd, peak day • 842 existing homes (14% of total residences) are located in the Lumber River Basin 4.1.1 Existing Water Supply Alternatives Due to the District’s proximity to multiple water systems in the region, the most viable water supply alternatives include surface water and groundwater. PWC, LCFWASA, and the City of Lumberton all have existing water treatment capacity to sell potable surface water to this District. Additionally, the location of approximately 2,470 residences within the Hope Mills MIA creates the possibility that Hope Mills could sell water supplied from PWC to Cumberland County if these customers were to be served by the proposed Southwest District. PWC is the closest surface water system and has a large transmission system that can provide water to the Southwest District with relatively lower start- up construction costs. LCFWASA and the City of Lumberton would have to construct many miles of water transmission systems that cross County boundaries in order to provide water to the Southwest District. It should be MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 20 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 noted that LCFWASA is planning for the Bladen Bluffs Regional WTP to be operational in 2012. Potential IBT issues related to surface water transfers to customers located within the Lumber River Basin are discussed in Section 5.2. Groundwater systems that could provide water service to the Southwest District include Robeson County, Bladen County, and Hoke County. Koonce, Noble & Associates, Inc. is currently evaluating the costs for Robeson County and Bladen County to provide water service to the Southpoint community. During this analysis, it has become evident that each of these systems would have to develop additional groundwater supply wells and treatment capacity to provide the long-term water demand for the Southwest District. Although Hoke County is the furthest from the District, a water main could be constructed south of Rockfish Creek to serve the District. Similar to Robeson and Bladen Counties, it would be necessary for Hoke County to construct more wells and treatment capacity in order to sell the projected volume of water to the Southwest District. 4.2 Linden Water & Sewer District The Linden Water & Sewer District was formed in February of 2003 by the Cumberland County Board of Commissioners. The Linden District is located in the north central portion of Cumberland County within the Carvers Creek Township. The northern boundary of the District borders the Lower Little River (Harnett County boundary), and the eastern and southern boundaries of the District border the Cape Fear River. The western boundary is generally defined as the limits of the Fayetteville and Spring Lake MIAs. When it was formed in 2003, the District had an area of approximately 37.6 square miles (24,084 acres). Incidentally, there is a gap between the service areas of the current Linden District boundary and the Fayetteville MIA that spans an area of approximately 6.7 square miles. This gap is along Slocumb Road and McBryde Street from the Cape Fear River to US-401. In this report, it is recommended that this gap in potential service area be served through the expansion of the Linden District boundaries to meet the Fayetteville MIA. The proposed Linden District boundary can be seen on the maps provided in Appendix A. At present, this relatively new District has limited water infrastructure located within the town limits of Linden along with distribution mains along US-401 and NC-217. The Town of Linden owns and operates the existing distribution system separate from the Linden Water & Sewer District. Harnett County operates a separate water system, the Northern Franchise Area, in northern Cumberland County. The Northern Franchise Area is located within the Spring Lake MIA and serves approximately 1,500 water customers in the residential developments along the US-401 Corridor, Elliott Bridge Road and Elliott Farm Road. Currently, Linden Water & Sewer District is in the final planning stages to begin construction of Phase 1A: approximately 10 miles of water distribution mains to serve approximately 200 rural customers located within the District. This project is considered a stepping stone for the construction of rural water service in northern MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 21 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 Cumberland County. These current plans for construction make the Linden District a high priority for Cumberland County to consider future water infrastructure projects within the District. The following summarizes the critical attributes of this proposed Water District: • Total Service Area = 44.3 square miles, 1,204 existing homes • Total Service Area includes 4.4 square miles within the Linden MIA • Total Service Area includes less than 50 existing homes within the Linden MIA • 85% Connection Rate = 1,023 projected water customers • 39 miles of water pipeline to serve this customer base (estimated NCDOT roads only) • 26 customers per mile of NCDOT roads • Start-Up Year 2013: Projected Water Demand = 0.247 mgd, avg. day; 0.371 mgd, peak day 4.2.1 Existing Water Supply Alternatives According to the preliminary engineering report prepared for the Phase 1A Linden project, water purchased from Harnett County Public Utilities is the most economically beneficial to the customers located in this District due to the presence of water supply mains from the Harnett County water system. Phase 1A of the Linden Water & Sewer District is expected to begin construction in 2010 and be operational in 2011. Due to the District’s location, the most viable water supply alternative is limited to surface water. Harnett County, PWC, and City of Dunn all have existing water treatment capacity to sell potable surface water to this District. Additionally, the location of the Town of Spring Lake creates the possibility that Spring Lake could sell water supplied from PWC and/or Harnett County to portions of the Linden District. 4.3 East Central Water District The proposed East Central District is located in the eastern portion of Cumberland County in the Cedar Creek Township. The eastern boundary of the District borders the South River (Sampson County boundary), the southern boundary of the District borders NC-210 and Ava Road, the western boundary of the District borders John B. Carter Road, and the northern boundary of the District borders Maxwell Road. It should be noted that the proposed East Central District boundary is equivalent to Cumberland County U.S. Census Tract #28 (37051002800). The proposed District boundary can be seen on the maps provided in Appendix A. The East Central District is considered as the third priority given the relatively high density of customers located within this part of the County, as well as the high number of customers located within the Bethany Community. The following summarizes the critical attributes of this proposed Water District: MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 22 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 • Total Service Area = 41.6 square miles, 2,145 existing homes • Total Service Area includes 13.6 square miles within the Stedman MIA • Total Service Area includes 535 existing homes within the Stedman MIA • 85% Connection Rate = 1,823 projected water customers • 57 miles of water pipeline to serve this customer base (estimated NCDOT roads only) • 32 customers per mile of NCDOT roads • Start-Up Year 2016: Projected Water Demand = 0.461 mgd, avg. day; 0.691 mgd, peak day • 1,754 existing homes (96% of total residences) are located in the South River Basin 4.3.1 Existing Water Supply Alternatives Due to the District’s proximity to multiple water systems in the region, the most viable water supply alternatives include surface water and groundwater. PWC, LCFWASA, and Harnett County all have existing water treatment capacity to sell potable surface water to this District. Additionally, the location of approximately 535 residences within the Stedman MIA creates the possibility that Stedman could sell water supplied from PWC to Cumberland County if these customers were to be served by the proposed East Central District. Eastover Sanitary District is capable of selling water to the East Central District after construction of its second phase. ESD Phase 2 is expected to be under construction in 2009 and operational in 2010. PWC is the closest surface water system and has a water transmission system that currently provides water to the Town of Stedman and Eastover Sanitary District. However, this is on the eastern perimeter of the PWC system and the ability to transfer water to the East Central Water District may require significant start-up construction costs. LCFWASA and Harnett County would have to construct many miles of water transmission mains that cross County boundaries in order to provide water to the East Central District. Potential IBT issues related to surface water transfers to customers located within the South River Basin (Cape Fear River Sub-Basin 2-4) are discussed in Section 5.2. Groundwater systems that could provide water service to the East Central District are limited to Sampson County. Similar to Robeson and Bladen Counties, it may be necessary for Sampson County to construct more wells and treatment capacity in order to sell the projected volume of water to the East Central District. 4.4 Southeast Water District The proposed Southeast District is located in the extreme southeastern portion of Cumberland County in the Beaverdam and Cedar Creek Townships. The eastern boundary of the District borders the South River (Sampson County boundary), the southern boundary of the District borders Bladen County, the western boundary of the District borders the Cape Fear River, and the northern boundary of the District borders NC-210 and Ava Road. It should be noted that the proposed Southeast District MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 23 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 boundary is equivalent to Cumberland County U.S. Census Tract #29 (37051002900). The proposed District boundary can be seen on the maps provided in Appendix A. The Southeast District is considered as the fourth priority given the relatively lower density of customers located within this part of the County, as well as the large scale of the District and its sparse road network. The following summarizes the critical attributes of this proposed Water District: • Total Service Area = 119.2 square miles, 2,566 existing homes • Total Service Area includes 0.0 square miles within municipal MIAs • 85% Connection Rate = 2,181 projected water customers • 119 miles of water pipeline to serve this customer base (estimated NCDOT roads only) • 18 customers per mile of NCDOT roads • Start-Up Year 2019: Projected Water Demand = 0.575 mgd, avg. day; 0.863 mgd, peak day • 850 existing homes (33% of total residences) are located in the South River Basin 4.4.1 Existing Water Supply Alternatives Due to the District’s proximity to multiple water systems in the region, the most viable water supply alternatives include surface water and groundwater. PWC, LCFWASA, and the City of Lumberton all have existing water treatment capacity to sell potable surface water to this District. Eastover Sanitary District is capable of selling water to the East Central District after construction of its second phase. ESD Phase 2 is expected to be under construction in 2009 and operational in 2010. Similar to the East Central District, PWC is the closest surface water system to the Southeast District and has a water transmission system that currently provides water to the Town of Stedman and Eastover Sanitary District. PWC’s ability to transfer water to the Southeast District may require significant start- up construction costs. LCFWASA and Lumberton would have to construct many miles of water transmission mains that cross County boundaries in order to provide water to the Southeast District. Potential IBT issues related to surface water transfers to customers located within the South River Basin (Cape Fear River Sub-Basin 2-4) are discussed in Section 5.2. Groundwater systems that could provide water service to the Southeast District are limited to Sampson County and Bladen County. It will be necessary for Sampson County and Bladen County to construct more wells and treatment capacity in order to sell the projected volume of water to the Southeast District. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 24 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 4.5 Northeast Water District The proposed Northeast District is located in the extreme northeastern portion of Cumberland County in the Black River and Eastover Townships. The northern boundary of the District borders Harnett County, the eastern boundary of the District borders the South River (Sampson County boundary), the western boundary of the District borders the Cape Fear River. The southern boundary is generally defined as the limits of the Eastover Sanitary District service area, which was recently expanded for the ESD Phase 2 project. The Northeast is considered as a lower priority given the relatively lower density of customers located within this part of the County, as well as the presence of multiple water systems that are relatively isolated east of the Cape Fear River. The following summarizes the critical attributes of this proposed Water District: • Total Service Area = 40.1 square miles, 554 existing homes • Total Service Area includes 21.6 square miles within municipal MIAs of Wade, Godwin, and Falcon • 85% Connection Rate = 471 projected water customers • 37 miles of water pipeline to serve this customer base (estimated NCDOT roads only) • 13 customers per mile of NCDOT roads • Start-Up Year 2022: Projected Water Demand = 0.129 mgd, avg. day; 0.194 mgd, peak day • 324 existing homes (58% of total residences) are located in the South River Basin 4.5.1 Existing Water Supply Alternatives Due to the District’s proximity to multiple water systems in the region, the most viable water supply alternatives include surface water and groundwater. PWC, Eastover Sanitary District, Harnett County, and City of Dunn each have existing water treatment capacity to sell potable surface water to this District. Eastover Sanitary District is capable of selling water to the East Central District after construction of its second phase. ESD Phase 2 is expected to be under construction in 2009 and operational in 2010. Similarly, the Towns of Falcon and Godwin could sell water supplied from Dunn to portions of the Northeast District. The City of Dunn and Harnett County are the closest surface water supply systems. Dunn owns a water transmission system that currently provides water to the Towns of Falcon and Godwin, while Harnett County supplies the Linden Water & Sewer District located across the Cape Fear River. Harnett County’s ability to transfer water to the Northeast District may require significant start-up construction costs. Potential IBT issues related to surface water transfers to customers located within the South River Basin (Cape Fear River Sub-Basin 2-4) are discussed in Section 5.2. Groundwater systems that could provide water service to the Northeast District are limited to Sampson County and the Town of Wade. It will be necessary for Sampson County and Wade to construct more wells and treatment capacity in order to sell the projected volume of water to the Northeast District. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 25 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 5.0 Water Supply Resources in the Region This section discusses the existing raw water supply resources in the region. Many of these resources are currently utilized by other water users, including private citizens, private water corporations, and a wide array of municipal and county governments. These resources are considered as viable water supply alternatives for potable water supply that could be developed, sold, or allocated for Cumberland County’s needs. 5.1 Available Surface Water Supply The discussion of available surface water supply is limited to major streams, rivers, or existing impoundments within the region. All of these supplies are currently utilized by other water users and the withdrawal of any surface water for public use must be reviewed and approved by NCDENR Division of Water Resources, among other agencies, during the environmental review process. 5.1.1 Cape Fear River The Cape Fear River serves as the primary water supply source for the largest water users in the region including Harnett County, City of Dunn, Fayetteville PWC, and LCFWASA. For each of the raw water intakes located along this segment of the Cape Fear River, the water source is classified as WS-IV. PWC estimates the drainage area of the watershed to be approximately 4,360 square miles at the point of withdrawal. The US Geologic Surveys’ latest 7Q10 flow statistic for the Cape Fear River at Fayetteville is 625 cfs (404 mgd). Twenty percent of the 7Q10 flow for the Cape Fear River at Fayetteville is equal to 125 cfs (80.8 mgd). However, PWC’s 2002 Local Water Supply Plan indicates that the safe yield of the Cape Fear River at the raw water intake is 85.8 mgd. Therefore, this higher safe yield will be referenced in this report. 5.1.1.1 Jordan Lake Water Supply Storage Allocations According to the “Jordan Lake Water Supply Storage Allocation Round Three Hearing Officer’s Report,” published in June 2002, numerous applicants located within the Cape Fear River and Jordan Lake watersheds applied for water supply storage allocation in the latest round (Round Three) of water supply allocations. According to this report, the Round Three allocations are effective until 2030. NCDENR Division of Water Resources has calculated that the total water supply pool of Jordan Lake can provide a safe yield of 100 mgd. As of 2002, 63 mgd has been allocated to the participating applicants: Cary/Apex, Chatham County, Durham, Holly Springs, Morrisville, Orange County, OWASA, and Wake County-RTP. Although Harnett County and PWC applied for 18 mgd and 10 mgd respectively, none of the Jordan Lake water supply storage was allocated to either party in Round Three. For this report, it is important to examine how the final 2002 allocations in Jordan Lake were determined by NCDENR-DWR as they relate to two potential water suppliers to Cumberland MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 26 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 County: Fayetteville PWC and Harnett County. NCDENR- DWR used the water demand projections provided by applicants to determine the projected 2050 water supply needs of each applicant. PWC projected the 2050 water supply withdrawal from the Cape Fear River could be as much as 79 mgd and 114 mgd, average and maximum day demands, respectively. Similarly, Harnett County projected the 2050 water supply withdrawal from the Cape Fear River could be as much as 36 mgd and 54 mgd, average and maximum day demands, respectively. According to NCDENR-DWR, under all model scenarios through 2050, Harnett County and PWC’s water demands were completely satisfied on a daily basis through utilization of the existing water resources available. It is important to note that this excludes drought management of any kind anywhere in the Cape Fear River Basin and despite a projected increase in total upstream (from Fayetteville) withdrawals of 161% compared with 2000. Therefore, NCDENR-DWR has determined that the Cape Fear River is an adequate water source for Harnett County and PWC despite the combined use of all water utilities in the Cape Fear River Basin through 2050. 5.1.1.2 Intake Capacity Limitations Relative to 7Q10 Streamflow The following discussion is from the “Jordan Lake Water Supply Storage Allocation Round Three Hearing Officer’s Report,” published in June 2002, page 24. The US Geologic Surveys’ latest 7Q10 flow statistic for the Cape Fear River at Fayetteville is 625 cfs (404 mgd). Twenty percent of the 7Q10 flow for the Cape Fear River at Fayetteville is equal to 125 cfs (80.8 mgd). The administrative rules for the NC Environmental Policy Act (SEPA) require environmental documentation for expansions of water treatment plants that increase capacity by 1.0 mgd or more or result in a design withdrawal equal to or greater than 20% of the 7Q10 flow of the contributing stream (15A NCAC 01C.0504(3)). This is a requirement for study and environmental documentation, not a limit on water withdrawals. Fayetteville PWC and/or Harnett County may be required to provide environmental documentation before expanding their water treatment plant or water supply intake on the Cape Fear River for future capacity upgrades. However, according to all the information available to the NCDENR-DWR, the amount of water available during the 7Q10 streamflow event from the Cape Fear River will not be the limiting factor for future water supply withdrawals for PWC or Harnett County. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 27 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 5.1.2 South River The eastern boundary of Cumberland County is the South River. The South River is a relatively small, swampy, and darkly stained river. Below Big Swamp, the South River is supplementary classified as an Outstanding Resource Water (ORW) by NCDENR-DWQ. ORW is a supplemental classification intended to protect unique and special waters having excellent water quality and being of exceptional state or national ecological or recreational significance. To qualify, waters must be rated “excellent” by DWQ and have one of the following outstanding resource values: outstanding fish habitat or fisheries, unusually high level of water-based recreation, some special designation such as NC or National Wild/Scenic/Natural/Recreational River, National Wildlife Refuge, etc., important component of state or national park or forest, or special ecological or scientific significance (rare or endangered species habitat, research or educational areas). 5.1.3 Glenville Lake (Little Cross Creek Watershed) Glenville Lake is the southernmost lake within the Little Cross Creek watershed area. The four lakes located within the Little Cross Creek watershed are in the following downstream order: Bonnie Doone Lake, Kornbow Lake, Mintz Pond, and Glenville Lake. Glenville Lake WTP receives raw water supplied from an intake on Glenville Lake as well as transfer capability from the Cape Fear River and Cross Creek. A 36” raw water transmission main from the Cape Fear River to Glenville Lake WTP allows the transfer of additional raw water to this facility for treatment during periods of high demand within the water system. PWC estimates that the Little Cross Creek impoundments, including Glenville Lake, have a watershed drainage area of approximately 15 square miles with a combined safe yield of approximately 5 mgd. 5.1.4 Big Cross Creek Watershed The Cross Creek watershed is a highly urbanized watershed that drains mush of northern Fayetteville. During periods of severe drought, Cross Creek has been utilized as a supplemental raw water source for the Glenville Lake WTP. PWC estimates the drainage area of the watershed to be approximately 9.0 square miles at the point of withdrawal with a maximum withdrawal capacity of 2 mgd. 5.2 Interbasin Transfer of Surface Water to Serve Cumberland County Districts The main stem of the Cape Fear River, where PWC, Harnett County, and LCFWASA withdraw their current water supply, is located within the Cape Fear Sub-Basin 2-3. An Interbasin Transfer (IBT) Certificate is required for a new transfer of 2 mgd (maximum day demand, net) or more between major river basins and river sub-basins. Therefore, IBT will be a major factor in determining the most advantageous water source to serve the rural customers located in separate river basins (and sub-basins) from the region’s largest water supply, the Cape Fear River. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 28 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 This is significant for Cumberland County to consider because it means that large water sellers that utilize the Cape Fear River for source water, PWC for example, will not be allowed to sell more than 2 mgd (maximum day demand, net) to all water customers, existing and proposed, located across the South River Sub-Basin boundary without returning a significant amount of wastewater for treatment and discharge back into the Cape Fear River or obtaining an IBT Certificate. Net (total) IBT is calculated as follows: Net IBT = Withdrawal from Source Basin – (Consumptive Losses to Source Basin + Wastewater Discharge to Source Basin). 5.2.1 IBT from Cape Fear River Basin to South River Basin The South River, along with large areas of rural eastern Cumberland County, is located in a separate Sub-Basin 2-4 known as the South River Sub-Basin. The boundary between these two sub-basins is located along the ridgeline just a few miles east of the I-95 corridor for the northern half of the County; the boundary continues to NC-24 before turning southeastward and running along the ridge between Beaver Dam Church Road and Old Fayetteville Road and leaves Cumberland County. This basin boundary can be seen on the maps provided in Appendix A. The water system information provided by PWC indicates that a 24” water main runs along NC-24 between Fayetteville and Stedman. The 24” reaches the ridgeline, reduces to a 12” diameter water main, and then enters a pumping/metering station that fills the elevated tank in Stedman. Downstream of this metering station, the water main continues approximately four miles to the Town of Stedman. The capacity of this 12” pipeline is less than 2 mgd (approximately 1.3 mgd at 2.5’ of friction headloss per 1,000’ of pipeline). Therefore, PWC does not require an IBT Certificate to operate this water main because the system is limited to transfer less than 2 mgd (maximum day demand) between Sub-Basin 2-3 (main stem of the Cape Fear River) and Sub- Basin 2-4 (South River). Currently, PWC sells water to a single bulk customer in the South River Basin, Stedman. PWC also receives wastewater from Stedman which balances the Net IBT equation. In the near future, significant portions of Eastover Sanitary District Phase 2 will purchase from PWC and these rural customers, served by septic tanks, will result in a net loss of water from the Cape Fear River Basin 2-3. In the future, the Net IBT in the region may require a more detailed analysis to determine the extent of PWC’s viable water service area in eastern Cumberland County. Although PWC receives wastewater from NORCRESS, this flow is primarily from customers located in the Cape Fear River Basin 2-3. In 2009, there were approximately 2,928 potential County water customers located within the South River Basin. Using the same water demand projection methods as discussed in Section 2.4, this translates to an average daily demand of 0.9 mgd (maximum daily demand of 1.3 mgd) inside the South River Basin within 20 years. The following table illustrates the amount of MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 29 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 water that could potentially be sold to these customers from PWC, Harnett County, or LCFWASA; water sales of this quantity that are not returned to the source basin may result in an increased Net IBT that could push any one of these water systems closer to the threshold of requiring an IBT Certificate. Table 5 - 20-Year Water Demand Projections for Customers in South River Basin Proposed Water District Potential Customers (2009) Residential Water Demand (2029) 20% Commercial & Industrial Reserve 10% Estimated Daily Unaccounted Water Total Average Daily Water Demand Total Peak Daily Water Demand (P.F. = 1.5) Northeast 324 74,557 14,911 8,947 98,415 147,622 East Central 1,754 403,618 80,724 48,434 532,776 799,163 Southeast 850 195,596 39,119 23,472 258,187 387,280 Totals 2,928 673,771 134,754 80,852 889,377 1,334,065 It is important to note that the IBT legislation only covers surface water transfers. The utilization of groundwater resources in the region could be a way for Cumberland County to alleviate any IBT concerns that are raised during discussions with potential surface water providers. 5.2.2 IBT from Cape Fear River Basin to Lumber River Basin A small segment of southwestern Cumberland County is located in the Lumber River Basin (DWR 9-1). The boundary between the Cape Fear River basin and the Lumber River Basin is located along the ridgeline that follows Chickenfoot Road to the I-95 corridor; the boundary reaches the Roslin community and turns westward and runs along the ridge that makes up McDonald Road and Upchurch Pond Road before leaving the County. This basin boundary can be seen on the maps provided in Appendix A. The water system information provided by PWC indicates that a few existing residential water mains cross this boundary and serve a small number of customers located within the Lumber River Basin (along Chickenfoot Road). This small customer base represents a low water volume that is returned to PWC via wastewater collection mains and is not a major IBT consideration. In 2009, there were approximately 842 potential County water customers located within the Lumber River Basin. Using the same water demand projection methods as discussed in Section 2.4, this translates to an average daily demand of 0.26 mgd (maximum daily demand of 0.38 mgd) inside the Lumber River Basin within 20 years. The following table illustrates the amount of water that could potentially be sold to these customers from PWC, LCFWASA, or City of Lumberton; water sales of this quantity are not likely to adversely affect the Net IBT of any surface water systems in the region. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 30 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 Table 6 - 20-Year Water Demand Projections for Customers in Lumber River Basin Proposed Water District Potential Customers (2009) Residential Water Demand (2029) 20% Commercial & Industrial Reserve 10% Estimated Daily Unaccounted Water Total Average Daily Water Demand Total Peak Daily Water Demand (P.F. = 1.5) Southwest 842 193,755 38,751 23,251 255,757 383,635 5.3 Available Groundwater Supply In 1991, the Lumber River Council of Governments (LRCOG) and the US Geological Survey (USGS) sponsored an effort to monitor ground water levels in the LRCOG's four-county region. The initiative to further analyze the groundwater resources in the region resulted in the creation of the Southern Coastal Plain Ground Water Program (SCPGWP) is a regional, multi-stakeholder effort to examine ground water in the counties of Scotland, Hoke, Robeson, Columbus, Bladen, and Sampson Counties. In 1998, the LRCOG adopted a five-year plan that was designed to undertake research and development in the following key areas: groundwater supply & demand, quality, water level monitoring, hydrogeologic framework, and the development of ground water planning resources. In 2003, the Wooten Company published the final draft of the “Southern Coastal Plain Ground Water Resource Strategic Plan” that is considered the most comprehensive groundwater evaluation for the Southern Coastal Plain region. There are five major aquifers that underlie Cumberland County that can be considered available for source development, listed from the deepest to the shallowest as follows: Bedrock, Lower Cape Fear, Upper Cape Fear, Black Creek, and Surficial. It is the opinion of Koonce Noble & Associates and Marziano & McGougan that the Upper Cape Fear and the Black Creek aquifers are the most suitable potential groundwater supply source for Cumberland County to consider viable for this type of rural county- wide project. This is based on many years of experience with the design, construction, and ongoing expansion of groundwater supplied well systems in Hoke and Robeson Counties and other clients that utilize groundwater well systems. Additionally, our numerous contacts within the well drilling industry agree with the opinion that the Upper Cape Fear and the Black Creek aquifers are the only viable source of groundwater development available to Cumberland County. 5.3.1 Bedrock Aquifer The bedrock is composed of massive, impermeable rocks and depth to bedrock generally ranges from 100 feet to 350. The potential of the Bedrock Aquifer as a source of water supply is considered low with well yields typically around 5 to 35 gpm. Therefore, this aquifer cannot be considered a significant water source for Cumberland County. It could be utilized to supplement wells pulling water from other aquifers. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 31 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 5.3.2 Lower Cape Fear Aquifer The Lower Cape Fear Aquifer occurs directly above the Bedrock Aquifer and is overlain by the Lower Cape Fear Confining Unit. It is not present in Hoke, Scotland, and Robeson Counties, and only occurs in Cumberland in the Southeast corner of the county. The cities of Elizabethtown in Bladen County and Clinton in Sampson County use water from this aquifer. Salt water intrusion has been detected in this aquifer East of Elizabethtown. Due to the intrusion, the Lower Cape Fear Aquifer would not be considered a good water supply source for Cumberland County. 5.3.3 Upper Cape Fear Aquifer The Upper Cape Fear Aquifer is located throughout Cumberland, Bladen, Columbus, Hoke, Robeson, Sampson, and Scotland Counties. It is confined beneath the Upper Cape Fear Confining Unit and well yields typically range from 200 to 400 gpm. This aquifer ranges in depth from 50 feet below sea level in central Cumberland County to 450 feet below sea level in Columbus County. Thickness of the aquifer under Cumberland County ranges from 110 to 120 feet. Saltwater intrusion has been detected in southeastern Bladen and eastern Columbus Counties. The “Southern Coastal Plain Capacity Use Investigation” by the North Carolina Division of Water Resources, June 2004 indicates that there are two areas where large cones of depression have occurred due to ground water withdrawals. One area is near Tar Heel in Bladen County and the other is near Elizabethtown also in Bladen County. The cone of depression near Tar Heel covers all of western Bladen County, part of eastern Robeson County and extends into southwestern Cumberland County. The Upper Cape Fear Aquifer serves as a principal source of water supply, especially in Bladen and Sampson Counties. In contrast, the aquifer is relatively under-developed in Hoke, Robeson, and Scotland Counties, where the Black Creek Aquifer accounts for nearly all ground water withdrawals. There could be future limitations on the quantity of water available, but the Upper Cape Fear should be considered a good source of water supply for Cumberland County since it is spread throughout the county and has good quality and yield. 5.3.4 Black Creek Aquifer The Black Creek Aquifer is present throughout the Southern Coastal Plain. The Black Creek Aquifer becomes semi-confined to unconfined in northern/northwestern portions of Robeson County, and throughout Hoke and Scotland Counties, as the aquifer becomes shallower. The only area where the Black Creek Aquifer is confined in Cumberland County is to the east of the Cape Fear River. This aquifer is up to 200 feet thick, and wells produce from 200 to 600 gpm of relatively high quality water. The water from this aquifer often has high iron content, which is treatable with filtration. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 32 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 The Black Creek Aquifer is heavily used in Robeson County. The Robeson County County-wide Water System has approximately 32 wells in the Black Creek Aquifer and withdraws 11 to 16 mgd. Several towns and industries in Robeson County also have wells in the Black Creek Aquifer. The City of Lumberton has four wells in the Black Creek Aquifer that pull 3.6 mgd, but these wells are subject to river recharge. Water levels in the aquifer in Robeson County are not being severely impacted due to a high recharge rate and high transmissivity. Areas where utilization is high and water levels are relatively unaffected include Hoke and Scotland Counties and northwestern portions of Robeson County. The Black Creek Aquifer could serve as a water source for Cumberland County. The water should be of good quality but could require filtration to remove iron. 5.3.5 Surficial Aquifer The Superficial Aquifer is an unconfined aquifer, which is present throughout Cumberland County. This aquifer is the shallowest aquifer in the area and is not generally used by municipalities because it susceptible to droughts and pollution. The resource potential of the Surficial Aquifer is considered to be too limited to serve the projected needs of Cumberland County. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 33 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 6.0 Alternatives to Provide Potable Water Supply to Districts An alternatives analysis has been prepared to determine the best path to provide long-term water supply to the rural residents of Cumberland County. The selected alternative is critical in determining the most environmentally friendly and cost effective alternative for initial and future projects to be successful. In this report, the Southwest Water District is considered the highest priority due to its high potential customer density. See Appendix C for construction cost estimates of each alternative to serve the Southwest Water District. 6.1 No Action Alternative The first alternative to be analyzed in this report is the decision to take no action. A no action alternative by Cumberland County would be contrary to the purpose of this study. A no action alternative would ignore the growth in future years due to the projected growth rate from normal growth patterns as well as the accelerated growth from BRAC. Cumberland County would defer any responsibility to serve residents within the rural areas of Cumberland County to other entities. In the past, Cumberland County officials have been reactive to public needs relative to water distribution and supply. The purpose of this study is to develop a proactive scheme whereby, the County can participate in providing water supply and distribution to its rural citizens. Prior to this study, Cumberland County officials has engaged and financed other studies to be performed by other engineering firms dating back many years. To date, no significant implementation of any recommendations from these previous studies has been performed by Cumberland County. As a result, the demand for water service has continued to rise over time without a regional water system put into service. An example of this is the formation of the Linden Water & Sewer District in northern Cumberland County. During its initial formation in 2003, there was enough public pressure to cause the district to be formed. However, there was not enough public support for the passage of a bond referendum in order to finance the first phase of a water distribution project. Additionally, septic tank failures in Cumberland County continue to occur at a regular rate. These failures coupled with shallow wells in relatively sandy soils and also during drought periods generate a great deal of insecurity among the County’s citizens. Failing septic tanks can cause groundwater contamination and require construction of new wells in addition to septic tank replacement. This is a significant financial burden on the citizens and places further demands on the existing groundwater supplies. For these reasons, the engineers do not believe that a “No Action Alternative” would serve the long-term interest of Cumberland County and its citizens. 6.2 Alternative #1 - Develop County-Owned Surface Water Supply A feasible alternative for Cumberland County to provide water supply to its citizens would be to construct a new surface water treatment facility that would be owned and operated by Cumberland County. This alternative would require Cumberland County to perform the following: MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 34 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 • Form a fully staffed and equipped water utility department. A variation of this would be to keep the existing public utility department for administrative purposes only and outsource the operation and maintenance of the surface water utility. • Construct a new 5.0 mgd water treatment facility located on the Cape Fear River (or South River) with a properly sized raw water intake, finished water storage facilities, and high service pumping facilities. A benefit of this alternative would be that Cumberland County would be fully self sustaining with regard to the projected water supply and treatment needs for the 20- year planning period. Therefore, Cumberland County would be in complete control of its water expansion needs for the foreseeable future and no major inter-local agreements or water purchase agreements would be necessary to develop or acquire source water supply. Also, this would eliminate the need to renew or renegotiate these water purchase contracts as conditions potentially change over time with regard to water requirements. A disadvantage of this alternative would be that Cumberland County would need to construct a surface water treatment plant with a much larger capacity than is needed in the initial years of implementation. To construct a new surface water treatment facility at an economically sustainable price, the facility must be constructed to supply a 20-year demand cycle and be capable of supplying the projected maximum daily flow during that period of time. Therefore, the initial phase of the Cumberland County water system would require the construction of a 5.0 mgd facility to supply the first phase of the Southwest Water District. The cost of this extra capacity must be borne by the initial users and would require significantly higher end user charges via their monthly water bills and/or capacity fees. 6.3 Alternative #2 - Develop County-Owned Groundwater Supply Another feasible alternative for Cumberland County to provide water supply to its citizens would be to construct a new water treatment facility that would receive its supply from existing groundwater sources. As discussed in Section 5.3, Cumberland County has five levels of aquifers within the county. Two of these aquifers (Cape Fear and Black River) appear to have sufficient supplies to provide the projected 5.0 mgd of water supply during the planning period. The development of this alternative would rely heavily on approximations of the capacity of groundwater wells before they are constructed. For this report, we will assume that a minimum 200 gpm well can be achieved as justified in technical documents and surrounding water systems that utilize these aquifers. A 5.0 mgd water demand translates to a total of 35 wells that would need to be constructed in various areas of the county as new districts are developed and water distribution lines are constructed in new phases. Assuming these wells would be constructed in 1.0 mgd production increments, there would need to be an estimated five well fields in various parts of Cumberland County (approximately seven wells per field). It is assumed that each separate well field would be spaced sufficiently far apart to justify its own specialized treatment system to remove iron, sulfides, organics, hardness, and other pollutants. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 35 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 The benefit of this alternative is similar to that of Alternative #2 with regard to being fully self sustaining. A disadvantage of this alternative is the use of groundwater wells for a significant supply to a growing customer base. Groundwater resources in the Cape Fear and Black River aquifers are being used significantly by joining counties which will probably have negative effects on the groundwater supply in the long term. Additionally, the presence of the Central Coastal Plain Capacity Use Area (CCPCUA) in nearby counties is an indication of the extreme sensitivity of groundwater aquifers in this region. The CCPCUA may also be a potential indication of future groundwater use reductions that could advance inland due to over development of these resources. 6.4 Alternative #3 - Water Purchase Contract from Existing Provider This alternative would require Cumberland County to enter into a contract with an existing water system for the purposes of purchasing potable water to supply the County's potential customer base. Cumberland County is fortunate that there are several large purveyors of water nearby to the proposed District service areas. The major providers of potable water available to Cumberland County include: Public Works Commission of Fayetteville, Harnett County Department of Public Utilities, and the Lower Cape Fear Water and Sewer Authority. Of these three major water purveyors, only PWC is strategically located to serve all the proposed water districts in Cumberland County. This is due to PWC’s central location in the County and the proposed District locations along the outer perimeter of the County from the north to the southwest in a crescent shaped area. Currently, preliminary water cost data is available from PWC to make a financial feasibility analysis of the cost-effectiveness for this alternative. For this reason, this report will evaluate PWC as Alternative #3a using the per 1,000 gallon rate charged by PWC for water supply and O&M costs. For comparative reasons, Alternative #3b will evaluate Lower Cape Fear Water & Sewer Authority using identical per 1,000 gallon rates for water supply and O&M costs but with an additional capital cost for the 56,000 linear feet of transmission main that must be installed to connect with this potential supplier. Further discussions with Lower Cape Fear Water & Sewer Authority (or other provider such as Harnett County) may lead to a more economical solution in specific districts if the proposed per 1,000 gallon rate charged for water supply and O&M costs is more affordable than the preliminary rates offered by PWC. 6.5 Cost Comparison of the Feasible Water Supply Alternatives Each of the three feasible supply alternatives is compared on the basis of an end-user (residential) monthly water bill. The capital cost for the three feasible supply alternatives is developed by determining the amount of monies required to implement the following water system components: raw water supply, treatment system, capacity fees, existing system upgrades/interconnections, and the transmission, distribution, and storage system to carry the water to the end users. Once the capital cost is developed for the alternatives, the annual debt service for each alternative is calculated for a 100% loan on equal financing terms. Finally, the annual cost for water supply and operation and maintenance of the system is calculated for each alternative, and the total annual budget is to be repaid by the initial customer base with a zero fund balance. The following cost summaries illustrate the projected user rates for Alternative #1, #2, and #3 to serve the Southwest Water District. See Appendix C for construction cost estimates of each alternative to serve the Southwest Water District.

Because the Southwest District is relatively large and contains nearly 5,000 potential customers, the entire Southwest Water District cannot be served in a single project phase. This report uses an estimated Phase 1 water customer base of 1,500 connections and an average daily demand of 1.0 mgd for the first phase of water system construction. The following assumptions are used to calculate the monthly water bill for a Phase 1 customer in the Southwest Water District (Alternative #1, #2, and #3): • Southwest District is constructed as first phase in rural water system • Cost for first phase of water transmission/distribution/storage is $6.4 million • Cost for initial capacity fees and interconnection requirements is $3.4 million • Zero grant contribution for each alternative (100% loan) • Full loan amount borrowed over 40-year term, 4.0% interest • Average daily water demand of 1.0 mgd • 1,500 water customers (100% connection rate) • Per 1,000 gallon rate for water supply established by PWC ($2.00 per 1,000) • Per 1,000 gallon rate for O&M service established by PWC ($0.50 per 1,000) In Alternative #1 and #2, the cost per 1,000 gallons for the bulk water charge and the cost per 1,000 gallons for the O&M charge is based upon comparable charges from similar water systems in the region. As discussed in Section 6.4, Alternative #3 charges for bulk water and O&M utilize the prevailing PWC rates. Capital cost for water supply and treatment facilities are based upon current market trends for raw materials, manufactured hardware/supplies, and labor in the construction industry. Alternative #1 and #2 have a higher capital cost when compared to Alternative #3. Alternative #1 assumes that the capital cost allows for the construction of a 5.0 mgd supply system. This is because a new county-owned surface water treatment facility would require construction of a plant with the capacity to meet the projected water needs for the 20-year planning period (5.0 mgd). In the case of Alternative #2 and #3, it would be possible to phase the capital cost of the supply system since it would not be necessary to construct all of the required well fields and/or purchase capacity from outside sources until such capacity was needed. Therefore, when inspecting the following tables for each of the three alternatives described above, it can be seen that Alternative #3 yields both the lowest capital cost and the lowest estimated monthly water bill to the customer. 6.6 Selection of Recommended Water Supply Alternative One of the most important recommendations to be developed in this rural water is the selection of a long-term water supply method to be implemented by Cumberland County. A matrix chart is presented below that lists important considerations in selecting the most advantageous water supply method. A point system is used in the matrix that indicates the alternative that would create the least impact on Cumberland County resources, political, social, and economic. A score of 1 is considered the least adverse impact among the alternatives and a score of 3 is considered the greatest adverse impact among the alternatives. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 41 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 Table 7 – Feasibility Matrix for Water Supply Resource Consideration Alternative #1 Alternative #2 Alternative #3 Capital Cost 3 2 1 O&M Cost 2 3 1 User Charge (Rate) 3 2 1 Environmental 3 2 1 Political/Social 1 2 3 Economy of Scale 3 2 1 TOTAL 15 13 8 Based on the feasibility matrix above, Alternative #3 is the recommended alternative for the water supply to Cumberland County (all proposed districts). This is because Alternative #3 presents the least amount of adverse impacts to the points of consideration that are fundamental to the implementation of a new water system of this scale. If the Cumberland County Board of Commissioners elects to adopt Alternative #3, negotiations should begin immediately with PWC to determine their level of interest in providing all of the water supply for the proposed water and sewer districts. There are other feasible variations to this alternative available to Cumberland County as follows: • Negotiate with the Lower Cape Fear Water & Sewer Authority for provision of potable water to portions of the proposed Cumberland County water system. • Negotiate with Harnett County for provision of potable water to portions of the proposed Cumberland County water system. • Negotiate with all three entities to determine if there would be a combination that would yield more economical results to the Cumberland County's water supply needs. IBT may be a key component in the consideration to diversify water providers to different Districts. 6.7 Summary Cumberland County officials and citizens are fortunate to have available several sources of water supply that can be used in developing a county-wide water distribution. The capital cost analysis, monthly water rates, and water supply feasibility matrix set forth selection criteria that the engineers deem appropriate in selecting the best water supply alternative. Cumberland County staff and officials must use their best judgment when selecting the most feasible long-term water supply alternative. Additional criteria can be added to the feasibility matrix to tailor it in such a way that it meets the county's needs for further consideration of each alternative. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 42 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 7.0 Infrastructure Financing Alternatives Major contributions to this section were excerpted from the previous study entitled, “Cumberland County: Rural Water Feasibility Study, April 2002,” as performed by Camp, Dresser and McKee consulting engineers. Additional information is excerpted from the NC Rural Center Funding Source Guide, USDA Funding Guidance, and U.S. Department of Commerce data. Several funding options are available to Cumberland County for obtaining financing for water infrastructure projects. This section provides a generalized account of local, federal and state funding programs available to qualified applicants in North Carolina. Section 8.1 provides a final recommendation for financing any projects that may develop as a result of this study Federal funding agencies that provide funds for water projects include the United States Department of Agriculture - Office of Rural Development (formerly the Farmers Home Administration) and the United States Department of Commerce - Office of Economic Development Administration. State funding agencies that provide funds for water projects include the North Carolina Department of Environment and Natural Resources - Division of Water Quality and the Division of Environmental Health, the North Carolina Department of Commerce - Division of Community Assistance and the Commerce Finance Center, and the North Carolina Clean Water Management Trust Fund. The Rural Economic Development Center is a State funded non-profit organization that also provides planning and construction grants to local governments for infrastructure projects. The Clean Water Bond Act of 1998 was a referendum that provided a total of $465 million in grants and another $335 million in loans for water and sewer projects that are managed by the following four state agencies: NCDENR, NC Department of Commerce, NC Clean Water Management Trust Fund, and the NC Rural Economic Development Center. 7.1 Department of Environment and Natural Resources The Department of Environment and Natural Resources manages the majority of the funds ($330 million in grants and $335 million in loans), equally divided between the Division of Environmental Health - Public Water Supply Section and the Division of Water Quality - Construction Grants and Loan Section. 7.1.1 Division of Environmental Health Within the Division of Environmental Health, the Public Water Supply Section manages three separate financing programs: N. C. Drinking Water State Revolving Fund (DWSRF) Loans; State Bond Loan; and High Unit Cost grants. The purpose of these funds is to finance projects for planning, designing, and construction of water systems. Eligible applicants include local government units such as counties, cities, towns, incorporated villages, sanitary districts, metropolitan water districts, county water and sewer districts, and water and sewer authorities. Applicants are judged on a priority point’s basis. There is a $3.0 million per fiscal year loan limit and a $3.0 million limit every third fiscal year for grants. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 43 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 The average annual residential water and sewer charge must exceed 1.5% of the applicant’s most recent Median Household Income (MHI) to qualify for a grant. The user charge must exceed 0.75% if only one utility (water or sewer) will be present at project completion. Repayment terms of loan funds are determined by the Local Government Commission, but cannot exceed 20 years. The interest rate for the SRF loans is one-half of the Bond Buyers Index adjusted semi-annually with the maximum rate being 4.0%. The interest rate for the State Bond loan funds is the State's current interest rate plus administrative expenses. 7.1.2 Division of Water Quality – Construction Grants & Loans Within the Construction Grants and Loan Section, there are three separate financing programs: High Unit Cost Grants, State Bond Loan Fund, and the State Revolving Fund (SRF). The loans and grants from the CG&L Section are for wastewater infrastructure and are not pertinent to this water study. 7.2 North Carolina Department of Commerce Finance Center Each year, the North Carolina Department of Commerce designates all 100 counties in North Carolina as a Tier 1, Tier 2, or Tier 3 County. These rankings are based on an assessment of each county's unemployment rate, median household income, population growth, and assessed property value per capita. The recently amended tier designation laws require that the 40 most distressed counties are considered Tier 1 counties, the middle 40 counties are considered Tier 2 and the 20 most prosperous counties are considered Tier 3 counties. In 2009, Cumberland County was designated a Tier 1 County, among the 40 most financially distressed Counties in the State. County tier designations determine the available amount of tax credits for job creation and business property investment in a list of eligible industries. They include manufacturing, motorsports, aircraft maintenance and repair, air courier services, warehousing, customer service call centers, research and development, electronic shopping and mail order houses, wholesale trade and information technology. Eligible businesses that locate in lower- tiered counties are eligible for larger tax credits than those that locate in higher-ranked areas. As part of the application process, eligible companies are required to offer employees subsidized health insurance, have clean tax records and environmental compliance. In Tier 2 and Tier 3 counties, companies must pay adequate wages. The Clean Water Bond Act of 1998 provided $20 million to be used for economic development. The Department of Commerce through the Commerce Finance Center administers these funds. The Act provides that the funds will be awarded in the same manner as the State's Industrial Development Fund (IDF) program. The funds are to be used to make grants to local governments (municipal and county) to pay the cost of clean water projects for the location or expansion of industries in the State. The funds are for grants, as opposed to loans. Grants will be awarded for projects that will have a favorable impact on North Carolina's clean water objectives. Projects may address new or existing water or sewer lines or equipment, construction of or improvements that will expand the capacity of existing wastewater treatment or water supply systems. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 44 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 Economic Development Bond funds may be used only in economically distressed counties or in counties with a population of less than 50,000. 7.2.1 Division of Community Assistance (CDBG Infrastructure Program) North Carolina Department of Commerce - Division of Community Assistance administers another grant program called the Small Cities Community Development Block Grant (CDBG) Infrastructure Program. The purpose of this program is to provide infrastructure funds for water and wastewater disposal systems for low and moderate income people, thereby creating viable communities with suitable living conditions to residents. With the exception of 22 entitlement cities and two urban counties that receive funds directly from the U.S. Department of Housing and Urban Development (HUD), all municipalities and counties are eligible to receive Small Cities CDBG funds. The maximum infrastructure grant available per community per project per year is $850,000. Multiple jurisdictions can apply jointly for funds. The City of Fayetteville is one of the entitlement cities and Cumberland County is one of the urban counties that receive funds directly from HUD, with the one exception that the Town of Linden may apply directly for CDBG funding. Applications are accepted only upon official announcement of program specifications and details by the Division of Community Assistance. 7.2.2 Commerce Finance Center (CDBG Economic Development Resources Program) Similar to the CDBG infrastructure program is the CDBG Economic Development Resources Program administered through the Commerce Finance Center. Economic Development applicants may apply for CDBG assistance for public water and sewer facilities to serve a specific business, direct loans for the purchase of private business equipment, or for new expansion construction. Public facility projects may involve grants for up to 75% of the proposed facility cost, with 25% to be paid by the local government applicant. Except for 22 entitlement cities and two urban counties that receive funds directly from HUD, all municipalities and counties are eligible to receive small cities CDBG funds. Multiple jurisdictions can apply jointly for funds. CDBG assisted activities must demonstrate benefit to Low and Moderate Income (LMI) persons. The same conditions apply to the City of Fayetteville, Cumberland County, and the Town of Linden as cited above. 7.3 Clean Water Management Trust Fund The purpose of the Clean Water Management Trust Fund is to provide financing for projects that specifically address water pollution problems. Eligible entities include Local Government Units and other political subdivisions of the State and non-profit corporations that have as their primary purpose the conservation, preservation, and MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 45 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 restoration of the State's environmental and natural resources. Grant funds are used to enhance and preserve surface water quality. Projects must enhance or restore degraded waters, protect unpolluted waters and/or contribute towards a network of riparian buffers and greenways for environmental, educational, and recreational benefits. Trustees favor projects which have the highest benefit to cost ratio and are supported by and integrated with local community programs, are timely, supplement other water quality initiatives, and which do not have sources of sufficient funding. 7.4 North Carolina Rural Economic Development Center Through the 1998 Clean Water Bond Act, the Rural Center administers three separate programs: the Capacity Building Grants Program, the Supplemental Grants Program, and the Unsewered Communities Grants Program. All three are grant programs targeted to assist rural, distressed local governments with critical environmental or economic development priorities. Currently, Cumberland County is not eligible to apply for these funds because it is considered one of the fifteen “urban” counties as defined by the NC Legislature. This is due to the population and urban environment present in the City of Fayetteville. 7.4.1 Capacity Building Grants The purpose of this program is to provide matching funds for units of local government to plan for needed infrastructure projects through development of Capital Improvements Plans, Preliminary Engineering Reports, Rate Studies, etc. Capacity Building Grants are limited only to municipal and county units of government in economically distressed areas of North Carolina. Applicants must address local economic development or capacity concerns. Priority is given to projects that address water and sewer infrastructure planning needs. The maximum grant amount is $40,000. The limited amount of money remaining from the 1998 bond referendum is distributed as capacity building grants for study purposes only. 7.4.2 Supplemental Grants The purpose of the Supplemental Grant Program is to provide funds to match federal, state, and other loan or grant program funds for projects that improve physical infrastructure and strengthen prospects for economic development in distressed areas of North Carolina. Eligibility for Supplemental Grants is limited to units of local government and qualified non-profit organizations for projects in economically distressed areas of North Carolina. For example, projects in Tier 1 counties as designated by the North Carolina Department of Commerce receive priority points over those located in Tier 2 or Tier 3 counties. Special emphasis is given to projects that upgrade or expand existing water and sewer faculties or develop new facilities where permanent jobs are created or retained. Grants normally will not exceed $400,000 and will not represent more than 50 % of the total project cost. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 46 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 7.4.3 Unsewered Communities Grants The purpose of the Unsewered Communities Grants Program is to provide funds for development of wastewater collection and treatment utilities in unsewered communities. In order to be eligible for this funding, the applicant must be a unit of local government with population less than 5,000 persons. The applicant must have a MHI less than 90% of the national MHI, as provided by the most recent U.S. Census data. Priority will be given to applications demonstrating most cost-effective alternatives given the severity of need. The maximum grant amount available is $3 million per project not to exceed 90% of the total project cost. 7.5 U.S. Department of Agriculture - Rural Development It is the engineer’s opinion that USDA has been the most consistent source of infrastructure funding for the past 40 years. The USDA water and wastewater programs are administered in North Carolina by the Office of Rural Development (RD). The purpose of the Water and Wastewater Loan and Grant Program is to construct, enlarge, extend, or otherwise improve water or waste disposal facilities providing essential services primarily to rural residents and rural businesses. Eligibility is limited to rural areas and towns up to 10,000 in population. Eligible entities include public bodies such as towns, counties, districts, authorities and other political subdivisions of the state, non-profit organizations and Indian tribes. Applicants must provide evidence that they cannot finance desired facilities from their own resources or through other sources at reasonable terms. The loan repayment period must not exceed the useful life of the facility being financed or 40 years, whichever is less. There are three different interest rates based upon the median household income of the area served by the facility to be financed. Median household income is derived from the most recent U.S. Census data. Loans to public bodies are secured by General Obligation Bonds, which require a vote by the public. If the County is approved for issuance of Revenue Bonds then a bond referendum is not required. Loans to "not for profit" organizations are secured by Deeds of Trust on fixed assets constructed or improved with loan funds and pledges of system revenues. Grants of up to 45% of the total eligible project cost (depending upon the MHI) are available in conjunction with loans for the purpose of reducing average user charges to a reasonable level based on comparable systems. In recent funding cycles, the maximum grant per project is around 40-45%, up to a $2 million cap in order to spread the available funds to the most qualified applicants. Grants are not available to applicants where the median household income of the service area exceeds North Carolina's MHI. 7.6 U.S. Department of Commerce - Economic Development Administration The purpose of the Public Works and Development Facilities Grant Program within EDA is to assist communities with the funding of public works and development facilities that contribute to the creation or retention of private sector jobs and alleviation of unemployment and under employment. Eligible entities include public bodies such as towns, counties, districts, authorities and other political subdivisions of the state, non-profit organizations and Indian tribes. Projects must be consistent with MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 47 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 the EDA approved overall Economic Development Program for the area in which it will be located. Projects must be in areas suffering from economic distress, i.e., unemployment rates exceeding the national average and PCI of 80% or less of U.S. average. Generally grants cannot exceed 50% of the eligible project cost; however, in some cases grants may be made not to exceed 80% of the project cost. 7.7 Financing Options Applicable to Cumberland County Of the multiple financing options discussed above, there are several sources of both grant and loan financing that are applicable to Cumberland County’s rural water needs. USDA has both grant and loan funds available for the type of rural water project proposed in this study. Grant funding is dependent upon the median household income for Cumberland County or a smaller, defined subdivisions of the county (townships, US Census tracts, US Census blocks, etc.). Specific areas of Cumberland County are below the threshold for grant funding consideration and are therefore eligible to apply for USDA grant monies. The remaining areas of Cumberland County are not grant eligible, but are qualified to apply for USDA loan monies. In order to secure a USDA grant, the County must also apply for a loan to cover the non-grant eligible portion of cost. USDA-RUS rates are competitive and attractive due to the ability to finance the project loan costs over a 40-year period. Application for project financing is made through the USDA regional office, located in Lumberton and managed by Steve Smith. Funding is on a first come, first serve basis. The USDA funding program is a worthwhile application process with a favorable outlook for obtaining both grant and loan proceeds to apply toward the initial project recommended in this study, as well as potential future phases. In an effort to increase economic activity during the current recession, the federal government has channeled federal stimulus monies through established state and federal agencies that traditionally fund infrastructure projects. These funds are part of the 2009 American Recovery and Reinvestment Act (commonly referred to as the federal stimulus package). Loans made in the first round of project funding are set to repay principal only (0% interest); the first round is currently underway, and shovel- ready projects are the complete focus of this first round in order to create jobs in the immediate future. Cumberland County may be able to apply for these types of zero- interest funds in the future if the funds are still available, study recommendations are well-received, water supply is secured, and all of the required action items recommended in this study are completed in an expeditious time frame. Other “conventional” federal funds for Safe Drinking Water Act projects are directed to NCDENR-Division of Environmental Health: Public Water Supply Branch. The Drinking Water State Revolving Fund (DWSRF) program is an immediate source of loan financing because of the low interest rates being offered to applicants, typically 2.0%. The yearly allocation per project is $3.0 million for water projects. The potential to receive monies from the DWSRF program and USDA could provide sufficient funding for the initial projects recommended in this study. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 48 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 The Federal Economic Development Administration is another agency that routinely makes Federal grants to projects provided the project is coupled with job creation or job retention, which can be accomplished in special situations. Grants for a single project are generally less than $1.5 million. However, Cumberland County could request a greater sum, particularly if there are sufficient jobs involved or if the project cost is large enough to need a higher level of grant financing. Each project is considered on a case-by-case basis. Other potential grant funding sources include the State's Commerce Finance Center and the CDBG Economic Development Program, both of which are based on the creation of jobs. That is to say, there must be an industry locating within the County or expanding its existing operation that will provide or create new jobs. While neither of these agencies are primary targets at this time, the County should remain aware of such programs and look for opportunities to capitalize on the availability of these funds. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 49 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 8.0 Final Recommendations 8.1 Recommended Project Financing Plan It is the engineer’s opinion that the best financing program available to Cumberland County is administered by the USDA-RD. Federal funding in rural areas has been consistent over the past four decades and the likelihood of future funding is high due to the continuing need throughout rural North Carolina and the United States for a safe, reliable, public water supply. North Carolina officials have been aggressive in promoting rural water projects and the federal allocation to the State has been above the national average. Funding is made on a first come first served basis; the likelihood of receiving a loan and/or a grant is very high provided there is a proven critical health need and a sufficient customer base to make the proposed project economically viable. Koonce Noble & Associates and Marziano & McGougan recommend that Cumberland County's primary funding strategy be geared toward the scope and cost that USDA-RD is accustomed to reviewing and financing. The following summarizes a typical USDA project that would most likely receive USDA-RD funding: • Critical health needs in rural areas that are evident and supported • Optimum project size is approximately $5 million • Customer density of approximately 15-20 houses per mile • Total customer base of approximately 1,000 customers • Recently, the maximum grant per project is around 45%, up to a $2 million cap It is also recommended that Cumberland County consider pursuing additional funding sources to supplement the funds available from USDA-RD. The most suitable source of these additional funds can be leveraged from the following funding programs: • Drinking Water SRF Low Interest Loans o Competition is high for these loans o Critical health need must be present o Interest rates are typically one half the current market rate (2.0 %) o Maximum yearly allocation per project is $3.0 million for water projects. • Economic Development Administration Grants o Competition is high for these grants o Primary focus of this program is the creation/retention of private sector jobs o Residents within the project’s feasible service area can benefit indirectly from these types of projects o Typical grant awards cannot exceed 50% of the eligible project cost o Maximum yearly allocation per project is $3.0 million for water projects MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 50 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 • Community Development Block Grants o Competition is high for these grants o Cumberland County receives grant funds directly from HUD o Cumberland County can channel part of annual allocation to a rural water project o Critical health need must be present o Project area must meet economic hardship criteria 8.2 Organization of Proposed Districts This report has demonstrated that rural residents in Cumberland County can benefit from a public water system. Because of the large expanse of the rural sections of Cumberland County, the physical barrier of the Cape Fear River, natural topography, and the location of multiple water systems and MIAs, the potential rural water service area must be subdivided into small sub-sections. Cumberland County must delineate potential water service areas with accepted boundaries (i.e. townships, census tracts) that can be interpreted easily by potential funding agencies. Another advantage of using defined, accepted boundaries for these sub-sections is that these boundaries will remain relatively unchanged over time and they can be updated with future population and income data when it becomes available. As described earlier in this report, these sub-sections of potential water service areas are referred to as “Districts” in this PER. The purpose of dividing the County into "Districts" is to facilitate the following: • Create a project scale that is not too large in scope for practical funding consideration and engineering feasibility • Determine the number of potential customers by District • Use the Median Household Income published for each District • Median Household Income is a primary factor in determining whether or not an area is eligible for grants and/or loans from state and federal agencies • Determining priorities for service which include overall feasibility relative to capital cost • Project future water demands and service populations • Increase the variety of potential water suppliers to strengthen Cumberland County’s position as a potential bulk water customer North Carolina is fortunate to have a wide range of organizational structures available that allow the provision of water and sewer services to the public. In the case of Cumberland County, the engineers feel that the form of organization to be used for providing water service to the County residents should be one that does not necessarily create another level of government between the County residents and the government of Cumberland County. Also, the organizational structure must enable the County to obtain public/private financing including grants based upon the revenues that will be generated from utilization of the water system. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 51 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 With the above in mind, previous studies prepared for Cumberland County have itemized the various organizational structures that are available for the provision of water and/or sewer. One of the more common organizational structures and one that is currently in use in Cumberland County is known as a Water and Sewer District. A Water and Sewer District is a County service district that is established by the County Board of Commissioners, described by a meets and bounds document, and is considered a separate unit of government. However, the Water and Sewer District, as established by the County Board of Commissioners, is administered by County Board of Commissioners as the governing body. This eliminates the need for an additional layer of government at the county level. Having a master plan that indicates the County's intention to form districts and analyze feasibility on the basis of districts provides an additional level of comfort to lending agencies when applications are made for funding. It also allows the County to assign priorities for service based on changes in growth patterns or environmental conditions. Water and Sewer Districts can apply for and obtain grants from state and federal agencies. Water and Sewer Districts can hold bond referendums and/or borrow money per General Statutes of the State of North Carolina. Additionally, County commissioners can levy a tax if necessary to support the water system, although this is a very rare requirement to support a financially insolvent water project. Cumberland County has already undergone the experience of creating a formal District during the 2003 establishment of the existing Linden Water and Sewer District (previously discussed in Section 3.1.9 of this report). This project was considered a stepping stone for the construction of rural water service in northern Cumberland County and could be viewed as a successful precedent in the establishment of a new water oriented unit of government in Cumberland County. Additionally, the engineers understand that the County is contemplating forming another such district in the Over Hills subdivision area near Spring Lake for the purpose of providing wastewater service to those residents. To facilitate the continuing involvement of the County Commissioners, Water and Sewer District steering committees can be formed in each district. The steering committees would be made up of citizens from that district that would be interested in actively pursuing installation of water facilities. Each steering committee would be managed by the Director of Public Utilities and periodic reports could be made to the County Commissioners that update the findings in this report or other changes that relate to the feasibility for construction of water facilities. At such time as it becomes apparent that installation of water service to a particular district becomes feasible, the Department of Public Utilities can update the County Commissioners and receive their approval to begin application for funding and subsequent environmental permitting and facility design. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 52 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 8.3 Potable Water Supply Cumberland County is somewhat unique in North Carolina because Fort Bragg and the City of Fayetteville are urbanized areas in the County while the remainder of the County (approximately 242 square miles or 37% of the entire County) has maintained a very rural and agricultural nature. Also, PWC is a major purveyor of water in the County and has the available supply to provide potable water to all rural residents in Cumberland County through the 20-year planning period. Section 6 of this report discussed the various water supply alternatives available to Cumberland County. The conclusion of this report, with regard to water supply, is that the primary focus for Cumberland County should be to pursue negotiations with PWC to supply the potable water for any public system that may be constructed on a district by district basis in Cumberland County. PWC has been the long term purveyor of water in Cumberland County and has worked closely with the County on previous projects in the past. Currently, Cumberland County does not have a water purchase agreement with PWC. Such an agreement will need to be negotiated prior to final implementation of this recommendation. Also, as mentioned in section 6, there are other variations for water supply available to Cumberland County. Harnett County has a fairly strong presence in northern Cumberland County by virtue of having been granted a franchise area by Cumberland County in the 1980s. Currently, there are in excess of 1,500 customers served by the Harnett County water system in northern Cumberland County. Additionally, Cumberland County serves the Town of Linden with potable water. The Town of Linden owns the water system and contracts all operation and maintenance to Harnett County. A copy of the operation and maintenance agreement between Harnett County and the Town of Linden is contained in the Appendix D of this report. Therefore, it would be prudent to contact representatives of Harnett County to determine if there is interest in providing water supply to the northern portion of Cumberland County. Also being planned is a new water treatment plant in Bladen County known as the Bladen Bluffs WTP. This new facility is being constructed by the Lower Cape Fear Water and Sewer Authority and is expected to be operational before the end of 2011. The new water treatment plant would be capable of supplying the southern portion of Cumberland County as indicated in Section 4 of this report. The engineers have met with officials of the LCFWASA and their engineers have requested additional information. It is expected that potential bulk water rates will be forthcoming before May 30, 2009. Additional meetings with representatives of LCFWASA will be necessary if the proposed water rates could provide a potential savings to the County. Other scenarios in which water providers could potentially sell water to specific districts within the County are provided in Table B.3 in Appendix B, “Potential Water Supplier Scenarios.” This table summarizes the water providers considered as viable sources for the varying district locations proposed in the County. The intent of this summary information is to increase the variety of available potential water suppliers in order to strengthen Cumberland County’s position as a potential bulk water customer. Using the district-specific information provided, Cumberland County has the tools to gage water demand needs, negotiate potential water sales partnerships, and water supply resources available to proposed districts within the County. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 53 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 8.4 Project Priority Priorities for construction of water distribution systems on a district by district basis have been given in Section 4 this report. The basis for selection of project priority is dependent upon the cost per customer and the number of customers per mile of roadway. By prioritizing the districts in this manner, the most cost-effective project will allow for the most users at the least capital cost. This means that user rates and initial capital cost will be kept to a minimum while serving the greatest number of customers in initial phases. With the above in mind, the priority list for construction of water system to serve each district is as follows: • Priority 1 - Southwest District • Priority 2 - Linden District • Priority 3 - East Central District • Priority 4 - Southeast District • Priority 5 - Northeast District Tables B.2, B.3, and B.4 presented in Appendix B provide physical data for each of the proposed districts itemized above. The timeline to construct the water system in each district will be based upon several factors. They include district growth, availability of funds, construction market, user charges, and last but not least environmental factors related to the health and safety of the public. If the only funding made available to a particular district were in the form of loan monies, the district that appears to be the most financially feasible at this time is the Southwest District. However, discussions should be entered into with the USDA-RD to determine if sufficient grants would be available to lower the user charges to an acceptable level. 8.5 Water System Operation & Maintenance When the County constructs a central water system in a water and sewer district, that district must be operated and maintained in State/Federal compliance for the entire service life of the system. The operation and maintenance of the water system includes many components, such as: • Operational personnel for testing, flushing, inspection and repair of system facilities • Administrative personnel for billing, training, management and overall responsibility • Construction equipment such as backhoes, trenching and boring machines for day-to-day construction operations of the system • Integration into the County's administrative system for providing employee benefits, training and other items associated with employment/labor laws • Physical plant facilities for housing of equipment and storage of materials and office facilities for operational personnel to include computer facilities and software necessary for billing and day-to-day contact with the systems customers MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 54 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 Selection of the most desirable operational and management scheme for Cumberland County may require the most diligent thinking of the County staff and elected officials. In the following discussion, the engineers will draw upon their experience with other systems in an effort to provide adequate information to Cumberland County in selecting a desirable operational scheme. Many County systems that have started essentially from scratch have developed their own operational and management system and assets. However, Cumberland County is somewhat unique because of the significant diversity between rural and metropolitan type areas within the County. In other words, Cumberland County has within its boundaries a significant supply of potable water and existing operational facilities that are operated by others such as PWC and Harnett County (and LCFWASA). Emerging trends within existing water systems in North Carolina include outsourcing all the various water system operations such as, billing, water treatment plant operation and, on a smaller scale, maintenance of water distribution systems (i.e. Eastover Sanitary District). Therefore, the engineers feel that Cumberland County officials should include negotiations with the major water purveyors in the area for system operation and maintenance when negotiating for water supply. There would be two agreements necessary for negotiation: • Water purchase agreement for the purpose of setting charges, and other contracts or arrangements for supplying potable water to the county's water infrastructure • System operational agreement for the purpose of operating and maintaining the system If USDA-RD funds be utilized for construction of the system, the term of the agreement will need to be 40 years. In making the assessment of these two potential contracts, the engineers are working from the philosophy that "joining" with an existing entity such as PWC carries with it a fairly large scale of economy. That means that Cumberland County’s water districts would be part of a larger entity and fluctuations in commodities such as electricity, chemicals, unfunded regulations and other unforeseen items pertinent to the system could be absorbed with less financial impacts to the County’s customers. The engineers stand ready to further discuss these items with the County staff and officials at their convenience and provide any additional information to assist in their decision. MARZIANO & MCGOUGAN, P.A. c o n s u l t i n g e n g i n e e r s ` 55 CUMBERLAND COUNTY RURAL WATER FEASIBILITY STUDY PRELIMINARY ENGINEERING REPORT AUGUST 2009 8.6 Summary The following summarizes the engineer’s recommendations relative to proceeding with implementation of developing a county-wide water system: • The primary source of funding is recommended to be the USDA-RD. General Obligation (GO) bonds have historically been the recommended source of financing from the USDA. However, revenue bonds are also acceptable and have recently gained much more acceptance in the USDA-RD North Carolina regional offices. • The engineers recommend that the County continue to form water and sewer districts, as previously done in the Linden Water & Sewer District, along the lines shown on the various maps in this report. These districts can be managed by the existing board of County commissioners. Close contact between the Commissioners and the operation of the districts can be maintained by utilizing the County’s Department of Public Utilities and setting up district steering committees of interested citizens. • The engineers recommend that the County actively seek a potable water supply, primarily from PWC. Additional negotiations should be held with officials of Harnett County and the Lower Cape Fear Water and Sewer Authority to determine the feasibility of supplying all or part of the County's water needs. The variation would be to analyze the feasibility of using a combination of these available water supplies. • Project priority is listed in the above section on a district by district basis. Priority is based upon obtaining the largest number of users for the least amount of capital cost. Under the current physical data available for the proposed districts, it appears that the Southwest District provides the best opportunity for establishing a county owned water distribution system. • The engineers recommend that the County negotiate with the existing suppliers of potable water to determine the feasibility of obtaining the operation and maintenance of the County’s future water distribution facilities from other existing operations.
