There are no water supply intakes in the portion of the ' watershed located in Camden Count and only a small portion y y p of the critical area of this watershed is in the County. The watershed is classified as a WS-IV Watershed by the North Carolina Department of Environment, Health, and Natural Resources (DEHNR), Division of Environmental Management (DEM). The Pasquotank River watershed is a supply source for the City of Elizabeth ' City. However, the intake from the Pasquotank River for Elizabeth City's water supply is not used except in emergency situations and thus has been used ' infrequently in the past several years. 'In addition to th is plan, Camden County has adopted, and will implement, ' the Camden County North Carolina Water Supply Watershed Protection Ordinance. Further, it has caused a map to be created showing the boundaries of the watershed. See EXHIBIT 1. The Ordinance and map will be used to minimize non - source pollution from run-off through density and buffer requirements and are designed to work in concert with existing County regulations such as zoning and subdivision design standards. 11 Hazardous and toxic chemical spills, particularly if they occur within the watershed boundary, pose a significant environmental threat. Camden County officials are cognizant of this threat given that the County -is crossed by transportation routes that facilitate the movement of hazardous and toxic chemicals in and through the jurisdiction. The State of North Carolina requires this management plan contain an inventory of the names and addresses of industries located within the Pasquotank River watershed as it occurs in Camden County, that report the use, storage, or manufacture hazardous materials. Also, the general spill containment procedures to be used by the County in the event of a spill through its emergency management authority must be addressed. HAZARDOUS MATERIALS INVENTORY Land use patterns in Camden County reflect the rural nature of the locality. Over 90% of the land area remains wooded or is used in agriculture. Industrial development is minimal. However, there are several commercial establishments that sell gasoline and other fuels located within the watershed area in the County. See EXHIBIT 2. The South Mills Water Association operates a water purification and distribution system.serving parts of both Camden County and Pasquotank County and the South Mills community. Discussions with the Emergency Management Coordinator serving Camden County, the City of Elizabeth City, and Pasquotank County, reveal that there are no reported inventories of hazardous chemicals within the watershed area located in Camden County. The Coordinator stated that the responsibility for completing - 2 - ' and filing hazardous chemical reports with the local fire departments and local emergency management agency falls upon the individual businesses, industries, and ' agencies using, storing, or manufacturing hazardous or toxic chemicals. The ' North Carolina Division of Emergency Management supplied a Tier Two Emergency and Hazardous Chemical Inventory sheet which describes a fuel storage location in the watershed area at a Carolina Telephone and Telegraph Company Central Office Building on Old U.S. Highway 17 North. See EXHIBIT 3. GENERAL SPILL CONTAINMENT PROCEDURES Response to hazardous or toxic chemical spills occurs when a report is made ' to the Central Communications Center serving Camden County, Pasquotank County, and the City of Elizabeth City. The effected fire department will be dispatched ' to the scene of the incident. The Emergency Management Coordinator is notified of the incident being reported and engages emergency response personnel as needed. Spills posing a threat to the Pasquotank River may necessitate the ' notification of United States Coast Guard and the United States Army Corps of Engineers. The City of Elizabeth City's water plant is not immediately notified ' since the City's water intake into the Pasquotank River is used in emergency situations, as previously discussed. The Elizabeth City Fire Department employs trained personnel, certified in hazardous materials handling, and must therefore be relied upon to respond to certain spill situations. The City's personnel are available through a Mutual Aid Firefighting/Emergency Incident Agreement ' involving fire departments serving Camden County within the watershed area. See ' EXHIBIT 4. State personnel can be called upon as well. Procedures, such as those set forth in the "Basic Plan Appendix 8 Hazardous Material," should be followed in the event of an incident. See EXHIBIT 5. These, or similar procedures, should be approved by the Local Emergency Planning Committee (LEPC) ' and the County. SUMMARY ' Camden County will continue to rely on existing agreements and general procedures as discussed herein to effectively handle hazardous or toxic chemical ' spills and facilitate containment. The County's fire departments, working in concert with those of neighboring localities, state and federal agencies, and the public, will implement this plan. 0 - 4 - CY) 1.)

SECRET'ARIL' CHIEF U.S. COAST GUARD SUPPORT CENTER COMMANDING OFFICER R CHIEF BASIC PLAN APPENDIX 8 HAZARDOUS MATERIAL EXHIBIT 5 I. PURPOSE This appendix provides additional information to the basic plan for response to hazardous material emergencies and to meet the jurisdiction's responsibilities pursuant to the Emergency Planning and Community Right -to -Know Act of 1-986 (Title III), Superfund Amendments and Reauthorization Fct of 1986 (SARA). II. SITUATION AND ASSUMPTIONS rA. Situation 1. The specific facilities involved with Hazardous ' Materials subject to the emergency planning requirements of Section 302 of the Super-6fund Amendments and Reauthorization Act of 1986 (Sc�A, ' Title III) are listed in the facility information notebook on file in the Central Communication Center. 2. The threat of a major disaster involving hazardous materials has escalated due. -to the increase in everyday use and transportation of -chemicals by ' the various segments of our population. 3. The results of a hazardous material incident could ' include the death or serious injury of persons exposed to the material, the spread of contaminants in varying degree throughout the ' County, and the destruction of property from fire, explosion, and exposure. ' 4. Evacuation, a protective measure, could isolate evacuees from their.homes for an indefinite period of time., r5. victims of a hazardous material incidents may require unique or special medical care not typically required in other types of emergencies. 6. The release: of hazardous materials may have short and/or long term health and environmental effects ' depending upon the chemical composition of the substance. ' 7. A hazardous material incident may affect several . hundreds of people within the jurisdiction without warning. Revised September 30,1991 BP-8-1 8. A hazardous material incident may require the public to shelter -in -place or to evacuate depend"ing'upon conditions at the time of the emergency. ' B. Assumptions This plan can be effective if the following assump- tions prove true: 1. Most, but not all, people affected by a hazardcus material incident' will follow instructions and shelter -in -place or relocate to designated shelters. ' 2. Public notification/warning and evacuation, if required, will be in accordance with the procedures described in the Notification and ' Warning Annex (Annex C) and the Evacuation and Transportation Annex (Annex I) of this plan. ' 3. The local jurisdiction must respond to the incident in the initial phase without assistance from outside the jurisdiction. It is assumed that ' emergency response agencies will take appropriate actions to prevent or minimize the spread of the material, provide early first aid as necessary, and manage the incident scene with emphasis ' toward safety of the public and responding personnel. ' 4. Planning and training prior to an incident will significantly reduce the risk to personnel. ' 5. The hazardous material involved in an incident can be identified within a reasonable period of time by the owner of the facility or the vehicle, by the shipping documents, 'by the properties of the 1 material itself, or by information provided pursuant to SARA, Title III or the. N. C. Right -to ' Know Act. 6. A facility involved in a hazardous material incident will provide all information required by SARA, ' Title III, Section 304 on a timely basis, including a written report. 7. Emergency response personnel are knowledgeable in the use of available resources. ' 8. The U. S. DOT Emergency Response Guidebook, alone or in combination with other information sources, is used as a guide for initial protective action at incidents involving hazardous materials; this ' guidebook is intended primarily for internal size - up of transportation accidents. Revised September 30,1991 BP. 8.2 CONCEPT OF OPERATION III. A. There are tNo types of incidents involving hazardous ' materials; (1) incidents at fixed facilities and (2) transportation incident. ' B. The level of response required for an incident is determined by: ' 1. the quantity and the toxic effects of the material involved in the release; ' 2. the population and/or property threatened; 3. the type and availability of protective equipment ' required for the released material, and; 4. the probable consequences should no immediate action be taken. incident, C. Depending upon the threat posed by the protective measures initiated for the safety of the public could include in -place shelter, evacuation, and isolation of the contaminated environment. D. Incidents are classified according to level of risk according to the Incident Commander's assessment. Level I (Potential Emergency Condition) is an incident ' which can be controlled by the first response agencies, does not require evacuation of other than the involved structure or immediate outdoor area, and does not indicate major environmental damage will occur. Level' II (Limited Emergency Condition) is an incident that involves a critical hazard with a potential threat to life or property, requires a limited evacuation of the surrounding area, or suggests that major environ- mental damage could occur. Initial response to the incident can be adequately handled by the jurisdic- tion's personnel and resources. ' Level III (Full Emergency Condition) is an incident an involving a severe hazard or large area, poses extreme threat to life and property, and will probably require a large-scale evacuation. Level III includes or. an incident requiring the combined expertise resources of local, state, federal and/or private ' agencies/organizations. E. Response procedures for each level of incident will be according to local policies and procedures in compli- ante with worker safety standards. Revised Sectember 30,190-1 ' F. This plan recognizes that a hazardous material incident can change with time, and necessitate escalating the response to a higher level, or down -grading the respon- se'* to lower levels as the situation is controlled. G. When responding to an incident where hazardous materials are known to be stored, the responders will assume the involvement of the most toxic substance at that location unless otherwise informed. ' H. A Local Emergency Planning Committee (LEPC) has been established at the jurisdiction level to identify the magnitude of the local hazard, assess the vulnerability of the community to that hazard, and provide planning guidance for emergency response. Representation on the LEPC is prescribed by the policy of the North Carolina ' Emergency Response Commission, and those. agencies or groups/facilities that have an interest in hazardous materials may have a representative on the committee. A point of contact (Facility Emergency Coordinator) will ' be identified at each covered facility under SA_A, Title III, Section 302. This Facility Emergency ' Coordinator will provide the necessary emergency response information on the facility to the planning committee. I. Notification of a release of a hazardous chemical may be provided by any one who recognizes that a release• has occurred. The telephone will be the primary means of alerting for any hazardous ' material incident, however, other methods including fire and other alarm systems may be•used for initial notification if accepted by the LEPC. (See Attachment ' 3 for recommended procedure.) J. Warning and notification .of. the public, including ' warning and notification to special populations such as the hearing impaired, will be accomplished in accord- ance with the Notification and Warning Annex (Annex C) ' of this plan. Procedures for warning that have been developed for the hazard* zones surrounding identified fixed facilities supersede the provisions of Annex C. I. As necessary, emergency vehicles with effective sound devices (sirens and/or public address systems) may be used as a public alerting system. If a fixed notifica- ' tion system is in place around the facility or emer- gency area the vehicles may be used as a backup system. The vehicles will be dispatched within the evacuation ' area and will stop at each quarter (1/4) mile in populated areas and at each house or group of houses that are more than 1/4 mile apart. The emergency ' vehicle will notify the public of the situation and/or recommend protective action. To ensure receipt of the Revised September 30,1991 BP.8.4 ' initial warning by all members of the community,,each route should be run twice if possible. The second run, or.backrun, will be to confirm alert and notification. ' Backruns need only stop at houses that are dark at night or where it is apparent that people are not com- plying with instructions. If necessary, door-to-dcor alerting will be accomplished during the second run. ' IV. ORGANIZATION AND ASSIGNMENT OF RESPONSIBILITIES ' A. General: The head of each agency involved in hazardous materials emergency response is responsible for the safety of its own personnel. Training, emergency response procedures, and medical surveillance shall ' comply with the provisions of the North Carolina Hazardous Waste Operations and Emergency Response ' Standard (13 NCAC 7C.0101 (a)(26)). Topics addressed shall include, but not be limited to the dangers of hazardous materials, -emergency response techniques, protective measures, protective clothing and equipment, ' and medical monitoring of personnel if necessary.

I. INTRODUCTION Camden County is located in the northeastern part of North Carolina. The County contains a total land area of 240.5 square miles. Camden County is bounded by Virginia on the north, Pasquotank and Gates Counties on the west, and Currituck County on the east. The North River bounds the County to the east, the Pasquotank River to the west, and the Albemarle Sound to the south. Elevations range from near sea level to 24 feet above sea level at the western edge of the Great Dismal Swamp. The Dismal Swamp comprises a major portion of the northern portion of the County while the Great Swamp occupies the south and east portions of the County. Ground water is the only source of usable water in Camden County. The depth to brackish water is normally more than 100 feet in the northern half of the County and less than 100 feet in the southern half. Limited quantities of fresh water are located in the surficial aquifers only. The water in these aquifers ranges from soft to very hard and generally contains excessive amounts of iron. Soils in Camden County are generally productive farmlands. The major crops include corn, soybeans, potatoes, cabbage, and small grain. The soils range from very poorly drained to well drained nearly level locations. Generally, the soils in Camden County that are well suited to crops are well suited to urban uses. In previous years, the Growth Management Plan for rural areas such as Camden County has been farming. The prices of crops have dictated growth in these rural farming communities. Today, the prices of crops are very low and the farming industry is declining. Camden County is no exception to this rule. ' Camden County is experiencing a large amount of residential growth, particularly in its northern areas. Unlike farming, residential growth will require adequate water and sewer facilities. It is Camden County's intention to allow the availability of water and sewer ' facilities to control growth. This report will provide a planning document to outline water and sewer resources available to provide a planned growth for Camden County. The preparation of this report was financed in part through a grant provided by the North Carolina Coastal Management Program, through funds provided by the Coastal Zone Management Act of 1972, as amended, which is administered by the Office of Ocean and Coastal Resources Management, National Oceanic and Atmospheric Administration. C 1 II. EXISTING FACILITIES The northern and southern portions of the County presently have separate rural ' water systems. The northern portion of the County is served by the South Mills Water Association (SMWA) and the southern portion of the County is served by the South Camden Water and Sewer District (SCW&SD). The County does not contain any ' community sewer systems. The following sections provide an overview of the existing water facilities in the County. I A. SMWA ' The SMWA system was constructed in the mid 1960's. The system started with approximately 85 users with a 100 gallon per minute (gpm) well and treatment consisting of aeration with the addition of chlorine. In the mid 1970's, the ' system was expanded to approximately 400 users with approximately 180 of the users located in the Morgan's Corner area of Pasquotank County. Today, the system has approximately 1,500 customers with approximately one half in Camden County and one ' half in Pasquotank County. The service area of the SMWA within Camden County is the South Mills Township which comprises the northern half of the County. ' SMWA has a history of problems with its water resource. Water is obtained from wells located in the surficial aquifer of less than 100 feet in depth. These wells are low yielding and high in iron and hardness. The first well was installed in 1963 and produced ' approximately 100 gpm and lasted nine years. The second well produced 60 gpm and lasted 10 years. Around 1976, twelve wells were installed. All but one of these wells had to be replaced. Until 1999, SMWA had nine wells which produced a combined total ' of 250 gpm. Another well was abandoned that year. Wells have been abandoned primarily due to the low yield and iron deposits causing well screens to fail. In 1999, SMWA expanded its production and treatment facilities. Eight new wells were added. ' The highest producing well was approximately 50 gpm. Total production of the 16 wells is 500 gpm. ' Up to 1999, water was treated with a 300 gpm pressure filtration and ion exchange softening plant. The treatment facility was expanded to a 600 gpm system with an additional pressure filtration and ion exchange softening train. The system has 75,000 ' gallon and 100,000 gallon elevated storage tanks and a 100,000 gallon ground storage tank. ' Availability of an adequate water source is a growth restricting factor for the water system. The SMWA is in constant search of additional wells to meet the demand as well as funds necessary to construct the wells. The surficial aquifer cannot yield adequate ' producing wells. Underlying water bearing stratas produce water which is too high in chlorides for conventional treatment and consumption. B. SCW&SD ' The SCW&SD was formed in the early 1990's with Phase I of the system complete in the mid 1990's. The system contains approximately 70 miles of 2" — 10" water mains and a 250,000 gallon elevated water storage tank. Potable water is supplied through bulk water purchase from Elizabeth City. The system has approximately 600 users. ' A funding application was made to USDA -Rural Development for additional water main extensions in the system consisting of a distribution system to serve the central portion of the County. USDA -Rural Development refused to fund the project unless Elizabeth City ' lowered its water purchase rate of $3.20 per 1,000 gallons or an alternative source of water was found. Due to eligibility of only 45% grant from USDA -Rural Development, a water treatment facility was not feasible with only 600 users and Elizabeth City would ' not commit to lowering its rates. The fund application for the distribution system expansion was withdrawn in 1998. ' In May of 1999, Camden County went to arbitration with Elizabeth City to get the rates lowered. In September of 1999 this arbitration forced Elizabeth City to lower the rates to $2.47 per 1,000 gallons; however, it is speculated that the water rates will go back to ' $3.20 per 1,000 gallons or higher in the very near future. k III. ALTERNATIVES AVAILABLE ' A. Water The purpose of this section is to analyze various sources of water available ' for Camden County as well as feasible service areas and distribution systems. 1. Water Resources Available ' a. Bulk Water Purchase iThere are three water systems surrounding Camden County: Elizabeth City, Currituck County, and Pasquotank County water systems. As previously discussed, SCW&SD presently purchases all its potable water from Elizabeth ' City. The District has a purchase contract for up to 4.5 million gallons per month. The District purchased water at a rate of $3.20 per 1,000 gallons. A recent arbitration got the ' rate lowered to $2.47 per 1,000 gallons; however, the rate is expected to be raised in the very near future. Due to the high rates and limited availability of water, it is not recommended that SCW&SD utilize bulk water purchase from Elizabeth City as a long- term water source. It is also pointed out that USDA -Rural Development will not fund any more water projects in Camden County until another source of water is found or Elizabeth City substantially lowers its water rates. ' Pasquotank County is in a similar situation as Camden County and has a limited supply of water. Pasquotank County has its own water source but also purchases water from ' Elizabeth City. Approximately 700 users in the northern portion of Pasquotank County are served by the SMWA. Utilization of bulk water purchase from Pasquotank County is not an adequate long-term water source for Camden County. ' Currituck County has its own water source which also has a limited capacity. Due to its limited capacity and the construction cost of a water main interconnection, bulk water ' purchase from Currituck County is not a feasible long-term water source. b. Surface Water ' Camden County is surrounded by surface water on three sides including the Pasquotank River, the North River, and the Albemarle Sound. Surface water as a potable water source is not a feasible alternative due to factors such as fluctuations in chloride concentrations, high levels of organic matter, color, and algae ' blooms. For this reason, there are no surface water facilities located in northeastern North Carolina. ' C. Ground Water Six major aquifers are identified in Camden County. They ' include the surficial, Yorktown, Castle Hayne, Beaufort, Upper and Lower Cape Fear aquifers. The Division of Water Resources has mapped these aquifers and performed studies of the hydrogeologic framework for the groundwater in the area. Potable ' groundwater supplies in the region are primarily found in the Surficial and Yorktown aquifers. Each aquifer has been mapped by the State and is described in detail in terms of regional elevation, thickness, and lateral distribution hydraulic properties in relationship ' to strateographic units, groundwater flow, and chloride distribution. The approximate positions of 250, 500, and 10,000 parts per million (ppm) chloride interfaces have been plotted for each aquifer, identifying where potable water supplies may be found, and ' where reverse osmosis treatment would be necessary in order to produce potable water. Declining water levels are documented throughout the region. SMWA is one of the few ' remaining entities utilizing the surficial aquifer for a water source. The wells are very low producing and SMWA is in constant search for new well sites and funds. As referenced in the Hydrogeologic Framework and Groundwater Resources of the North ' Albemarle Region, North Carolina, May 1998, prepared by the North Carolina Department of Environment and Natural Resources, Division of Water Resources, it is the recommendation that future water supplies to be located in the Yorktown and Castle ' Hayne aquifers. The location of an ample supply of fresh water is very doubtful and hit or miss at best. The State maximum contaminant level for chlorides is 250 ppm. It is anticipated that where an ample supply of water can be found, the chlorides will be above 250 ppm. As with Elizabeth City, Pasquotank County, and Currituck County, it is the recommendation of Camden County to pursue a reverse osmosis treatment facility. SMWA utilizes wells to draw from the surficial aquifer in the northern portion of the County. These wells are less than 100 feet deep. Although they are high in iron and hardness, chloride levels are within acceptable limits. However, these wells are very low ' yielding wells, typically less than 50 gpm. As the northern portion of the County continues to grow, it will become increasingly difficult to find an ample supply of water from the surficial aquifer. Waters higher in chlorides from the lower aquifers can be ' treated by reverse osmosis; however, the location of the discharge for the concentrate is difficult in this region. C The Garrington Island region in southeastern Camden County contains a water system serving a small trailer park and motel. The well for the water system produces water that does not require treatment other than disinfection to meet State standards for water quality. This well has been pumped at a rate of 600 gpm for 24 hours by the Division of Water Resources with only approximately 60-foot drawdown. Although the well has a high yield potential, it is uncertain the effects of long term high pumping rates on potential upconing of high chloride water from the lower aquifers. It may be possible to pump a well field at a lower rate for the use of a supplemental water source. 2. Distribution ' A majority of the feasible areas to provide water service to is presently served with the exception of the central portion of the County which is the northern portion of Courthouse Township. Studies have been performed which ' recommend the layout and sizing of distribution mains to serve the rural residences in this remaining unserved portion of the County. Studies have also been performed on the need for a large diameter transmission main from the central portion to the northern portion of I the County and the U.S. Highway 158 area. These systems will be presented in detail in following sections. B. Sewer ' Due to the expense of sewer systems, only the most populous regions of Camden County can be considered for a community sewer system. This section will review the types of collection and treatment facilities applicable to Camden County. 1. Collection Systems I Design data for pressure, gravity, and a combination of the two is presented in this section. a. Gravity Sewer Systems Gravity sewer layout and sizing is based on State's minimum sizing of 8" diameter PVC pipe at a minimum grade of 0.40% with manholes at maximum spacing of 400 feet. Topographical conditions of the County present the most difficulty in the gravity sewer system layout. At a grade of 0.40%, the depth of the gravity sewer pipe will increase 4' vertically for every 1,000' horizontally. Minimum depth is 3' of cover over the pipe. It is undesirable C and costly to install the gravity sewer main at a depth greater than 12' due to the high water tables in Camden County. Therefore, for every 2,500' of gravity sewer main, a pump station is required to lift the sewer up to the next section of gravity sewer mains. b. Small Diameter Gravity (SDG) Sewer Systems Small diameter gravity sewer collection systems consist of the installation of 6" PVC sewer mains installed at a minimum 0.10% grade with a cleanout every 400 feet maximum. Although the material cost is less, installation cost of the 6" SDG system is approximately equal to the 8" gravity sewer system of equal depths. This is due primarily to the complexity and required accuracy of installation. Some savings are obtained due to the more shallow cuts required. This system has not acquired the popularity in North Carolina as it has in some states such as South Carolina. ' The major problem with the SDG system is its reliability. The system is designed to handle effluent only. Septic tanks are required at each residence. However, solids and grease still tend to accumulate in the mains causing flow stoppage. Septic tanks must be ' pumped out at least once a year. Cleanouts are installed along the main in which equipment with jetting and vacuum capabilities is required for maintenance. On this basis, this system is not analyzed any further. ' C. Pressure Sewer Collection System In a pressure sewer system, sewage is pumped through small diameter pipes buried in shallow trenches which follow the land contour. It can be described as a potable water system in reverse. The system consists of a pump package ' system, service lines and force mains, and the discharge treatment point. A pump station is installed at each residence or can be shared by two residences. There ' are two primary types of pumps used: the grinder pump and effluent pump. In the grinder pump station, the solids are ground into slurry and pumped to the discharge point. An effluent pump is used in the STEP (septic tank effluent pump) system in which the ' pump is installed in the liquids end of the septic tank. The settleable solids and most of the grease accumulation remain in the septic tank. ' Service lines from the pump basin to the street are usually 1'/4" Schedule 40 PVC. Force mains are usually SDR 21 PVC pipe in sizes from 2"- 6". Sewage is pumped through the force mains to a discharge point consisting of the treatment facility or a gravity manhole. ' Pressure manysewers stems offeradvantages and disadvantages as compared to gravity Y systems. The obvious advantage of pressure sewer systems is the ease of installation. 1� u ' Typically, the largest line needed would be 6" in diameter. Pipe alignment can follow that of the road shoulder, narrow and shallow trenches, minimum equipment and labor, road and bridge crossings, elimination of large pump stations and manholes, and no ' infiltration or inflow are all advantages of the pressure sewer systems. Disadvantages consist of mechanical equipment, power outages, power costs, operating problems, ' easements, and unfamiliarity with pressure sewers. The residential pump station can be viewed as another home appliance and subject to the ' same ongoing service requirements as a home furnace, refrigerator, hot water heater, etc. The national average for power outages is two hours. The homeowner should refrain from washing clothes and taking showers during this period. When power is restored, all pumps will attempt to come on creating a high head, low flow condition. The pumps are ' equipped with thermal overload protection or designed to remain in operation for some time at no flow. Pumps nearest to the discharge point will empty first and systematically ' shut off until the system farthest from the discharge point is empty. After installation, the pump station will be buried flush with the ground and difficult to ' notice from the road. Control panels can be located on the side of the house in an inconspicuous location. The residents will have to grant permission to the County to have access to the pump station. ' 2. Treatment Facilities Treatment facilities available for Camden County consist of surface water discharges and land application. This section will give a brief description of each. ' a. Surface Water Discharge ' It may be possible to discharge treated wastewater into the Pasquotank River or the North River. It will be very difficult to obtain a discharge permit into the Albemarle Sound. It is pointed out that all discharges have been banned from the ' Currituck Sound. In order to meet the discharge limits stipulated by the Division of Environmental Management, a mechanical treatment facility will be required such as ' extended aeration and tertiary treatment. Utilization of constructed wetlands for these surface water discharges is possible. A constructed wetlands facility would consist of pretreatment, typically through a mechanical plant, filtration through the constructed ' wetlands, and then discharge through a swamp or drainage way to the river. u n ' b. Land Application ' Pretreatment is required prior to land application. For small communities, lagoons are usually the most practical form of pretreatment and storage. They are relatively easy to operate and require minimal maintenance. Lagoons ' offer consistency, ease of operation and maintenance, and low cost. The lagoons can also be used to provide the required 30-90 days of storage for wet periods when wastewater cannot be applied to the fields. ' Land application methods consist of subsurface and surface application methods. Subsurface application is generally more expensive than surface for community sewer ' systems. Subsurface application would consist of constructed trenches with gravel and perforated drain line. A typical system would consist of numerous subfields with several miles of drain line for a small community. ' Sufficient land area of suitable soils must be available for land application. In addition, a buffer zone is required for this land application which requires minimum setbacks of 150 ' feet from any property line, 400 feet from any residence, and 100 feet from surface waters. The spray field would consist of a permanent irrigation system with the distribution mains installed below grade or a system with movable spray guns such as a ' hose -drag -traveler that can be connected to hydrants located throughout the field. The land may be leased or owned by the wastewater system. A typical system would grow easily maintained vegetation such as grasses or trees. The system could also lease land ' from a farmer for growing crops such as soybeans, wheat, or corn but not crops that could be consumed raw such as cabbage. u 0 0 ' IV. PROPOSED ALTERNATIVES ' A. Water 1. SCW&SD Distribution System Expansion ' Camden County is made up of the SCW&SD and the SMWA. The SCW&SD is comprised of Shiloh Township and a portion of Courthouse Township. The ' SMWA service area is within the South Mills Township. In 1997, the SMWA acquired USDA -Rural Development loan/grant funds to complete ' extension of water mains into the remaining feasible areas of its service area. This section will concentrate its distribution growth areas in the SCW&SD areas. ' a. Population Growth The population growth within Shiloh and Courthouse ' townships has been primarily due to growth and development in the Elizabeth City area. In addition, there is some indication of retirees locating in Camden County, particularly the lower end of the County, and along the Pasquotank River. b. Population Projection IThe past growth trend, based upon census data, indicates there has been very little increase in permanent population in Camden County over the ' past twenty years; however, water demands will be reflected by this increase, as well as increase business development and seasonal or second homes. Water demand will be based upon all of these users, not just permanent residents. Table 1 illustrates population ' projections for the County and SCW&SD. Table 2 illustrates the water usage per customer based on 1998 data. 1 10 TABLE 1 POPULATION PROJECTION Area 1970 1980 1995 2000 2010 Camden County 5,453 5,861 6,100 6,250 6,262 (Permanent Pop.) So.

Water Demand Projections for Distribution Sizing ' Average day water requirements for the District were determined based on water consumption for the District in 1998. Based on monthly consumption and the number of metered connections, average demand was 3,450 gallons ' per month per connection, or 115 gallons per day. Table 2 summarized the water consumption for 1998. ' Water requirement is based upon 85-90% of potential users through 2010. Assuming approximately 2.8 people per household, water requirements for residential consumption is based on 1,380 users in the year 2000 and 1,540 users in the year 2010. Based on ' average monthly usage presented in Table 2 of 3,450 gallons per month per user, average day residential usage is approximately 160,000 gallons per day for year 2000 and 177,000 gallons per day for year 2010. Approximately 50,000 gallons per day is added ' for commercial usage in 2000 and 75,000 gallons per day is added for 2010. The initial average day demand projection for the enlarged District is approximately 210,000 gallons with the average day demand increasing to approximately 280,000 gallons by the year 2010. d. Water Distribution System ' The water distribution system for the SCW&SD has been analyzed through computer modeling in previous studies. The system modeling was ' performed by hydraulic analysis, which is an analytical method of predicting the system gradient (pressure) based on a given flow condition. ' Three basic distribution system analyses were modeled based on the projection of the demand: (1) the system capacity to supply the maximum day demand; (2) the system capacity to maintain a sufficient pressure range during a maximum hour demand period; ' (3) the system capacity to replenish storage following a maximum hour demand period. If the model showed insufficient pressure, high velocity in pipes, or a large amount of head loss, then the model was modified until satisfactory results were obtained. Water ' distribution systems storage is provided to supplement the peak demand periods and provide emergency storage. ' The lines were sized to provide a minimum pressure at the service meter, during the peak hour, of 30 pounds per square inch. As a general rule, a distribution system should have the storage capacity for an average day demand. The existing tank is sized for 250,000 gallons. This is less than the projected average day usage in 2010; therefore, a new 300,000 gallon tank is recommended to be constructed to provide adequate storage 13 ' capacity. Although the total storage is more than one day's average demand, the additional tank will help supplement the SMWA system as discussed later in the report. ' As previously discussed, the remaining unserved areas are located in the central portion of the County. The area was surveyed for locations of roads with an adequate number of ' houses to provide water main extensions. Figure 1 illustrates the location of roads with adequate house counts to justify water main extensions. This project would consist of approximately 158,000' of 6-inch water mains and 10,000' of 12-inch water mains. As ' discussed later in the report, a water production facility is proposed just south of the Camden Village which can supply water to the SCW&SD as wells as supplement the SMWA system. Therefore, this project will also consist of the construction of a new 16- ' inch water transmission main for the proposed water treatment facility to Camden Village and a 14-inch water transmission main to the Burnt Mills area or the service area boundary of SMWA. A 300,000 gallon elevated water storage tank is needed in the ' Burnt Mills area to provide pressure and storage for the northern service area of the SCW&SD and supply pressure and flow for water to the SMWA. Figure 2 illustrates the location of the needed transmission mains and water tank. e. Estimated Project Costs ' The estimated project costs for the water distribution system improvements to the central portion of the County are summarized in Table 3. The probable costs do not include inflation factors to predict future prices at the time of ' actual construction. The total estimated cost is $3,591,021. r 1 14 1208 1206 1145 1263 1265 1205 1203 1264 Spences Corner HIGHWAY 34 PASQUATANK RIVER ELIZABETH CITY 1207 11X1145 stings ner 1201 1202 elcross HIGHWAY 34 1 1136 1145 1137 1146 1135 1145 1136 / 1129 1129 1133 1135 1136 1134 Creek 1121 1135 MEW 1121 1122 Indiantown PROPOSED 6' WATER MAINS CAMDEN COUNTY PROPOSED WATER SYSTEM UPGRADE NOT TO SCALE FIGURE I Bumt Mills (Jonesboro) 300,000 GALLON TANK Lambs Corner ELIZABETH CITY �RO 14" WATER MAIN cc,Q ol �o G�4 5 �O �-1 ences -°p Comer ut 6"WATE -- MAI ' Hastingsl Comer Belcross A CAMDEN 6p Se PROPOSED CONCENTRATE DISCHARGE PROPOSED REVERSE OSMOSIS \ WATER TREATMENT PLANT NOTE: SERVICE ROUTE INCLUDES SR 1138 AND HIGHWAY 343 .

Introduction A source of potable water is a major limiting factor to the growth of northern Camden County. SMWA presently obtains its water from sixteen wells located in the surficial aquifer which produce very low -yielding wells. The wells ' are continually running dry causing the SMWA to be in constant search of new well sites and funding for new wells. ' Due to high water rates and a limited quantity from Elizabeth City, the need has been discussed for Camden County to construct a reverse osmosis water treatment facility to serve SCW&SD and SMWA. In addition, SCW&SD should install additional distribution mains to its rural water system and a 14-inch water transmission main to the service area boundary between SCW&SD and SMWA. ' The purpose of this section is to present the need and requirements to extend the transmission water main from the SCW&SD into the SMWA service area. The SMWA service area is the fastest growing portion of the County and is unable to meet its potable ' water needs. Additional water can be supplied from the proposed Camden County water treatment facility. This project will consist of approximately 72,500 feet of 12-inch water transmission main; a 300,000 gallon elevated water storage tank, booster pump station, ' and master meter vault. b. Water Demand Projections ' Population projections for Camden County have been presented in previous sections for SCW&SD and for Camden County. Camden County is ' becoming inundated with requests to build subdivisions. Developers are being put on hold until water supply issues can be resolved. Population growth for Camden County from 1970 to 1990 was 11 %, but this is expected to significantly change due to the influx ' of people from the Virginia area. -Growth from 1999 to 2019 is expected to be as high as 2% per year in the SMWA service area. The Camden County water treatment facility will be sized to serve a present day potential of 1,500 users in SCW&SD or 300,000 gallons per day (gpd). The initial plant size will ' be 500 gpm or 720,000 gpd. For treatment plant sizing purposes, the 20-year projection of water demands for SCW&SD is anticipated at 420,000 gallons per day for an average day demand and 700,000 gpd for a peak day demand. The water treatment facility is ' expandable to 1,000 gpm or 1,440,000 gpd. Plant surplus will be for the SMWA. 1 18 I C n SMWA has a present daily demand of 220,000 gpd. A 40% increase to the year 2019 will be a demand of 308,000 gpd. SMWA has recently received requests from five developers for water service to a total of a potential of 2,720 lots not including commercial and a potential school. Present average residential demand is 147 gpd. This equates to a present day residential demand of 619,840 gpd and a year 2019 average day demand of 707,840 gpd. Applying the same peaking factor as SCW&SD puts the 2019 peak day demand at 1,175,000 gpd. The year 2019 peak day demand for all of Camden County will be 1,875,000 gpd. Total water treatment facility capacity for the County will be at 2,304,000 gpd. However, well capacity will be at 1,805,760 gpd. SMWA will need to find at least three more wells at approximately 35 gpm to meet the water demand projections presented. C. Proposed Transmission System to SMWA The Camden County water treatment facility will have the capacity to supply 740,000 gpd to SMWA at build -out. A 14-inch water main is needed to supply water to the northern boundary of the SCW&SD. A 300,000 gallon elevated water storage tank will be built by SCW&SD at the end of the 14-inch water main. The proposed project will provide a water transmission main along N.C. Highway 343 and U.S. Highway 17 to supplement the SMWA water production facility with water purchased from the Camden County water treatment facility. The present SMWA water production and treatment facilities cannot supply all the present development demands plus anticipated growth projections. Continuation of well drilling in the surficial aquifer is not a long-term solution. The proposed project will install a master meter vault at the southern boundary of the SMWA service area. A water transmission main will be installed along N.C. Highway 343 and U.S. Highway 17 to the Virginia border to provide needed water to the area of highest development. At a potential flow of 740,000 gpd, a 12-inch water main is needed to prevent excessive head loss (i.e. 40 feet of head loss with a 12-inch water main versus over 120 feet of head loss to a 10-inch water main with a water tank providing only approximately 150 feet of head capability). The water transmission main will be used to fill a proposed 300,000 gallon elevated water tank just north of South Mills. An intermediate booster pump station will be needed to fill the tank. Figure 3 shows a layout map of the proposed transmission facilities. The proposed project is estimated at $2,993,387.

Maintenance on the water main can be performed by SMWA. 3. Proposed Water Treatment Facility a. Introduction ' An alternate water source is needed for Camden County. Wholesale water purchase rates from Elizabeth City are very high and are contractually limiting on the amount of water available. ' SCW&SD cannot expand its water system without an alternate water source. Declining water table levels and poor water quality as well as rapid population increases create a I need for the extended water system. SMWA obtains its water from the surficial aquifer and utilizes conventional treatment ' methods. An adequate supply of water cannot be found in the surficial aquifer to meet the needs of the SMWA. The Association is faced with the issue of finding an alternate water source to meet the needs of this population growth. ' The Division of Water Resources has documented declining groundwater levels in the Albemarle area and southeastern Virginia. Southeastern Virginia's withdrawal of ' groundwater has increased dramatically. Much of the declining water levels is due to withdrawals by Union Camp Corporation located in Franklin, Virginia. It has been documented that groundwater levels in the region have lowered as much as two feet per ' year. b. Demand ' Camden County would serve as the sole source of water supply for the SCW&SD and supplement the water supply for the SMWA. The SCW&SD presently has a contract with Elizabeth City which can be terminated when ' Camden County completes the new water treatment facilities. The initial phase of a _ water distribution system serving SCW&SD is under operation and plans have been made to construct an additional phase which will complete the District's system. A detailed analysis of the water demands for the SCW&SD was presented in the previous sections. ' Assume the statewide average demand at 5,000 gallons/month/user based on 1,500 users for the District is 250,000 gallons per day. For water supply planning purposes, 300,000 gallons/day is used for the 1,500 connections or 6,000 gallons per month each. The ' population is anticipated to continue its current growth rate. In the twenty-year period 1 22 L ' between 1970 and 1990, the County experienced about 11% increase in population. There is considerable building of new homes and subdivisions throughout the County. It is reasonable to assume the growth between 1999 and 2019 will be approximately 2% per ' year for a 40% increase. The water requirements will then be approximately 420,000 gallons for an average day or 700,000 gallons for a peak day. tThe water demand of SMWA is nearing 300,000 gallons per day. The water treatment plant facilities have been recently upgraded to 600,000 gallons per day. It is expected ' that SMWA will reach its capacity in the next ten years. C. Supply IThe Division of Water Resources has performed groundwater studies in the Camden County area as well as the northeast portion of the ' State. In May of 1998, a hydrogeological framework and groundwater resource evaluation was performed by the Division of Water Resources. Knowledge of the SMWA water supply was also used in evaluation of wells for the County. Figures 4, 5, and 6 illustrate a hydrogeologic cross sectional map of Camden County. Of interest in this map are the depths of the aquifers as well as the chloride isochlor lines. It ' can be seen that chloride levels are above 250 ppm found in the groundwater at depths greater than 100 feet. Basically, the surficial aquifer is the only fresh water available. However, this will not provide productive wells. Water supply from this project will be ' most likely from the Yorktown aquifer. The Yorktown aquifer in this region extends to approximately 300 feet. Chlorides can be in the range of 1,000-3,500 ppm. A reverse osmosis water treatment facility will be required to treat this water. The best water in the County is located in the very northwest corner of the County and in the Castle Hayne aquifer. Although reverse osmosis treatment will still be required, the ' chloride levels are lower in this region. The dilemma is with the required discharge for RO concentrate. The discharge waters for the RO concentrate will need to be brackish to nearly match the RO concentrate and not affect aquatic life. The discharge will need to ' be south of Camden Village in the Pasquotank River. The wells will have to produce 1,428 gpm for a twelve-hour operation period. Three ' wells are anticipated to meet this demand. The plant is projected for 500 gpm with a 70% recovery. 1 23 Union Cam 5 663 57B 55B s 55B66 At 55A3� 5 1 4 56A11 Dismal Swamp IRS 1 North Albemarle Ground Water Study Plate A-1: Hydrogeologic Cross -Section Location Map 60B4� C t VPI Creeds 61A Virginias° erton Swamp RSA State ine IRS -No-f-Th—C—arolivaort Kittrell Farm R Moyock D' 0 a Como IRS Buckland School -¢- SawyerAquafarm E Sunbury IRS• S.E.

Treatment Facility ' Based on the water quality in the area, a membrane (i.e., reverse osmosis) treatment process is required to adequately and efficiently treat the ' water. The plant should be designed for 1,500 connections at 6,000 gallons/month from the ' District or approximately 300,000 gallons/day. It is anticipated that 100,000 gallons/day will be immediately sold to SMWA. A 1.5 peak factor will put plant capacity at 600,000 gallons/day. Therefore, the plant will be set up for a 500 gpm flow or approximately 1 700,000 gallons/day. Growth for the next twenty years is expected at 2% per year for a 40% increase or up to 980,000 gallons/day within the next twenty years. This does not include any industrial prospects for the County. The plant will be set up to be expandable ' in the future to 1,000 gallons/minute or approximately 1.4 mgd. The plant will be located in a central portion of the County where a discharge location is ' easily accessible. Through discussions with State regulatory agencies, it is anticipated that the discharge will need to be on the Pasquotank River south of U.S. Highway 158. The County is in the process of acquiring land on Chantilly Road just south of Camden. ' The RO equipment will be housed in an engineered metal building or block building of simple design. It is anticipated the building will need to be approximately 3,000 square ' feet. The building would include a sectioned off area for a lab as well as an office for the operator and a SCADA system. ' Raw water from the wells will be fed through cartridge filters for pretreatment and then through the RO membranes for the final treatment. Chemical feed will consist of sulfuric acid for pH adjustment, anti-scalant to prevent membrane fouling, and chlorine disinfectant. High pressure pumps will be used to force water through the membranes at pressures ranging from 200-300 psi. ' Based on water quality, it is anticipated the recovery rate for the water plant will be approximately 70%. Thirty percent of the water will be concentrate discharged into the Pasquotank River. It is anticipated that a 6-inch water main will be utilized to extend to ' the Pasquotank River at the end of Chantilly Road. The Pasquotank River in this area is shallow along the edge so it is anticipated a short section of pipe will be directional bored into waters approximately 3-4 feet deep. This area also is attractive in that there are not a ' lot of wetlands along the edge of the river to create additional environmental issues. A full environmental assessment will not have to be prepared in that a discharge will be less than 500,000 gallons/day. At 1,000 gpm plant capacity, it is anticipated that the total 1 27 ' discharge will be 430,000 gallons/day at buildout. A draft discharge permit has been received for the water treatment facility and is attached in Appendix A. u e. Pumping and Storage ' A 500,000-gallon ground storage tank will be constructed at the plant site. Finished water from the RO plant will be pumped into the ground storage tank. Finished water pumps located in the treatment building can draw from the ' ground storage tank to pump into the system and maintain water levels in the remote elevated storage tanks. ' The SCW&SD has a 250,000 gallon elevated water storage tank that was constructed in the initial phase. The proposed expansion of the SCW&SD will also consist of an elevated storage tank which will serve the northern area of the District as well as provide a buffer tank for withdrawal by SMWA. f. Cost Estimates Total construction cost for the project is estimated at $2,930,000. This cost includes the water source, water production facilities, and the discharge. Tables 5 and 6 provide a breakdown for the construction cost and a summary of total project cost including engineering, inspection, and contingencies. Also attached is Figure 7 which illustrates a layout of the plant site. ' One hundred thousand dollars in equipment has been added which includes a utility bed vehicle with tools, lab equipment, computers, and spare equipment in the plant. The total ' project cost is estimated at $3,922,493. The annual operating budget for the SCW&SD and rates are estimated in Table 7. Expenses are based on a USDA -Rural Development loan/grant with 45% grant versus 0% grant. ' 4.

FACILITY LOCATION FACILITY SITE PLAN ' however, the quality is very good and does not require treatment other than disinfection. Appendix B contains water quality data available for the well. The Division of Water ' Resources installed a larger pump in this well and pumped it at approximately 600 gpm for 24 hours with no change in quality and very little drawdown. ' It is possible to install wells for the County in the vicinity of the existing well. These wells should be used only as a supplement to the Elizabeth City purchased water if funding for a permanent RO water treatment facility is not possible. Although the wells ' do not require treatment, there is a likely possibility of salt water intrusion from the lower aquifers if the wells are pumped hard for an extended period of time. ' It is recommended that two wells be installed with approximately 1,500' of separation. A new 8-inch water main would be needed along SRI 114 to connect to the existing 8-inch water main on N.C. Highway 343 and fill the existing water tank. As an example — two ' wells running 12 hours per day at 300 gpm could supply 1,500 Camden County residences at 3,450 gallons per month with a 2.5 peak factor. Test wells are needed to confirm flow, drawdown, specific capacity and quality. Table 8 presents a cost estimate for two wells and an 8-inch water main to the existing fl- inch water main along N.C. Highway 343. Figure 8 illustrates the system layout. ' B. Sewer Three areas of Camden County are potentially feasible to serve with a community sewer system. These areas are the Camden Village community and the U.S. Highway 158 commercial industrial/business area, the Camden Point community area, ' and the South Mills Village community area. The following will present the potential community sewer system for each area. ' 1. Camden Village Sewer System ' a. Service Area The Camden Village area is in the central portion of the ' County and includes two major highway corridors: U.S. Highway 158 and N.C. Highway 343. The corridors bisect the Camden community and their traffic flows offer ideal commercial and industrial sites if sewer is available. However, without a central ' sewer system, commercial growth cannot occur. The soils in this area have very limited capacity and will not support septic systems larger than a residential or possibly a very small business. Prospective businesses such as motels, grocery stores, or restaurants ' cannot locate here because of the lack of sewer facilities. The planning area also includes 1 33 1 L 1 TABLE 8 PROPOSED WELLS AND TRANSMISSION MAIN GARRINGTON ISLAND, CAMDEN COUNTY COST ESTIMATE 1) Test Wells 2 EA @ $12,000 $24,000.00 2) 8" PVC Water Main 26,000 LF @ $12.00 $312,000.00 3) 200 GPM Well, House, Chlorination 2 EA @ $160,000 $320,000.00 4) Telemetry LS $20,000 S) Land 2.2 AC @ $8,000 $17,600.00 Total $693,600.00 Contingencies (10%) $69,360.00 Engineer, Permit, Bid, Inspection $138,720.00 Grand Total $901,680.00 34 / 9 1137 1107 EXISTIN 50,000 GALLON 3 1121 ELEVATED ATER STORAGE TANK 113e ltza — �pq d•' 1138� 1133 7' 9 .6 7.) 1132 .� 1121 reel r ilia 1115 1132 7729 � -- � tie smnha •? � lira r � 1727 lin Battle Riddle PROPOSED GARRINGTOP ISLAND WELLS O 1114 .4 1109 P sell ' 7 PROPOSED 8" 'qSQ 2, '" WATER MAIN 1108 adelphla T "' 1110 toe EXISTING 8" Bea " WATER MAIN 1111 Alder Branch EXISTING 8" WATER MA{N 4 Old Tre 1112 0 Im U U 1100 1182 '— CAMDEN ,txi POINT 2� ALBE'MARLE SOUND lol 99 PROPOSED GARRINGTON ISLAND WELLS AND TRANSMISSI❑N MAIN NOT TO SCALE I FIGURE 8 the Camden Industrial Park. Plans for this industrial park were developed in 1997 for a 16-parcel site with an average of approximately nine acres per parcel. The County also ' wishes to serve the park with sewer. For many years, the County has encouraged and promoted commercialization and industry through the U.S. Highway 158 area to create jobs and to balance the public service cost of residential growth (i.e., schools). Finally, ' this system will serve two schools and potentially a third school. The project has a potential to serve approximately 450 residential users plus approximately 30 businesses along the U.S. Highway 158 corridor. In addition to the potential for future business/commercial development along U.S. Highway 158 and the Camden County Industrial Park, a preliminary analysis of an expanded service area and ' its feasibility for sewer has been performed. The analysis investigated the service area, construction costs, potential funding sources, and associated expenditures and revenues. It is potentially feasible to construct a $4.8 million sewer system with user revenue and ' funding from USDA -Rural Development, Department of Commerce, Rural Center, and local matches. Figure 9 indicates the potential service area for the Camden Village Sewer System. ' b. System Description ' The project can be broken into three systems according to funding availability. The first section is the Camden Village commercial and residential areas. Figures 10 and 11 illustrate the areas of sewer service to Camden Village ' commercial and residential areas. The system is laid out with a central sewer collection system with individual grinder pump stations at each residence and force mains along highway right-of-way. Sewer mains along U.S. Highway 158 will be gravity sewer main ' collection systems. The system contains approximately 57,000 feet of 2-inch through 8- inch force main, a large collection pump station, 297 connections, and a 400,000 gallon per day wastewater treatment facility. The wastewater treatment plant should be located ' on Chantilly Road and utilize the same discharge into the Pasquotank River with the RO water treatment plant. Total project cost is $3,267,000. Potential funding sources are $2,567,000 from USDA -Rural Development, $200,000 from the Rural Center, and ' $500,000 from Camden County. Tables 9 and 10 contain a summary of costs and potential funding sources. ! The second service area consists of the U.S. Highway 158 and N.C. Highway 343 area serving the Camden County schools and the County government complex. The service area is illustrated in Figure 12.

Tables 11 and 12 contain a summary of costs and potential funding sources. The last service area is the Camden Industrial Park and extensions along U.S. Highway 158 and is illustrated in Figure 13. This system would provide gravity sewer along U.S. Highway 158 and within the Camden Industrial Park. A series of pump stations and force mains would convey sewer from one gravity section to the next and eventually tie in to the wastewater treatment facility. The system consists of approximately 13,500 feet of 6-inch force main, 12,000 feet of gravity sewer, three large collection pump stations, and a potential of 94 connections. Total project cost is approximately $1,018,800. Potential funding may be from the Department of Commerce in the amount of $1 million. Tables 13 and 14 contain a summary of costs and potential funding sources. C. Budget Analysis Anticipated operating cost and user cost were investigated for the Camden Village sewer system assuming funding sources previously discussed and various grant amounts from USDA -Rural Development. The system was analyzed based on 80% participation and 100% participation. Projected sewer rates are illustrated in Tables 15, 16, and 17. 2. Camden Point Sewer System The residents in this project area have septic tank sewer systems that offer little protection from pollution. Due to the low elevation of the Camden Point area and the poor soils, several of the septic systems in the area are failing or in imminent danger of failing. To improve the quality of life in Camden Point and to provide facilities to protect the environment, the Camden Point area has received funding to develop a public sewer system. This section will summarize the proposed project. 43 TABLE 11 PUMP STATIONS AND GRAVITY SEWERS TO SERVE CAMDEN COUNTY SCHOOLS SUMMARY OF COSTS AND FUNDING SOURCES ➢ 5,000 LF of 6"- 8" FORCE MAIN ➢ 5,000 LF of 8" GRAVITY SEWER ➢ 2 PUMP STATIONS ➢ 3 CONNECTIONS ➢ TOTAL PROJECT COST ➢ CAPITAL OUTLAY FUNDING NEEDED $511,200 $450,000 44 TABLE 12 PUMP STATIONS & GRAVITY SEWER TO SERVE CAMDEN COUNTY SCHOOLS SUMMARY OF COSTS AND FUNDING SOURCES UTILIZING CAPITAL OUTLAY FUNDS ITEM ESTIMATED UNIT ITEM DESCRIPTION UNIT QUANTITY PRICE TOTAL Gravity Collection System 1. 8" PVC Sewers, LF 5,000 $ 30.00 $ 150,000 2.

Project Planning Area ' The project area generally consists of the Camden Point P J g Y area along the shores of the Albemarle Sound. Camden Point is located in the south end ' of Camden County, bounded to the North by Broad Creek and the North River, to South by the Albemarle Sound and to the West by SR1100. Figures 14 and 15 show the location of the project planning area. The project area is primarily wetlands, forest, water ' and vacant land with residential areas located along the Albemarle Sound. ' b. Environmental Resources Land use in the project area consists of residential ' properties and open, undisturbed woodlands and marshes. The developed areas are located along the southern side of Camden Point on the Albemarle Sound. Homes are constructed of unclassified fill material and are clustered around small canals constructed ' during early phases of development. Currently, no additional homes can be constructed because permits for septic systems cannot be obtained due to the unfavorable soil conditions. The entire project area lies within the 100-year flood plain. There are no ' major stream crossings within the project area. However, the lots in the western most developed area are bisected by a canal. Each lot has a small bridge across the canal. Crossing these canals will require CAMA and Army Corps of Engineers permits. There are no significant historical resources, endangered species, or critical habitats in the Camden Point area. I C. Growth Areas and Population Trends Growth within the Camden Point area has not occurred ' since the early 1970's due to the inability to obtain septic system permits. House counts performed in July of 1999 showed 53 homes in the area. A Rural Center Grant was received to serve the existing residents only and to eliminate an imminent health problem ' and environmental impact. Additional growth in Camden Point will occur only if the sewage facilities are upgraded to handle additional future connections. ' There is a potential of approximately 250 developable lots in Camden Point. Although most of the lots are primarily wetlands, conversations with the U.S. Army Corps of Engineers and Division of Coastal Management indicate the lots could support single ' family residences through Nationwide 18 Permits (less than 0.1 acre of fill in wetlands) and maintaining 75' separation between construction and surface waters. 1 52 TY (4h"l.�.l.3t LaA, �,,•t,,'�i 'p�ti'••x v y �r +�,(S.

Topography and Geology Located in the Coastal Plains physiographic province, Camden Point's topography is nearly level. Elevations vary from 5 feet MSL to a low of 0.5 feet MSL. e. Soils Soils in Camden Point consist primarily of Dorovan muck. This phase of the Dorovan series consists of land with 0 to 1 percent slopes, is frequently flooded and very poorly drained. Developed areas along the Albemarle Sound are Dorovan Muck overlaid with Udorthents loam, which is unclassified material consisting of dredge material created when the canals were dug. Along the northern coast of Camden Point, areas of Hobonny muck are present, primarily along the edges of Broad Creek, Little Broad Creek, and the north side of North River Point. This soil is nearly level, very poorly drained and consists at the surface of highly. decomposed organic material. West of Camden Point, along SR 1100, are small areas of Altavista sandy loam which is a fine sandy loam, 0 to 2 percent slopes and is moderately well drained, and Bojac loamy sand, which is nearly level and gently sloping well drained soils located on ridges. Both of these soils are cultivated or are natural woodlands. f. Existing Facilities The residences in Camden Point are built on small lots with originally shallow wells and septic tank systems. The shallow wells offered little protection from pollution. In 1995, a community water system was completed and funded by USDA -Rural Development serving the SCW&SD. This system is presently operating and paying for itself. However, due to high water table problems, many of the septic tank sewer systems in the community are failing, creating a continuing health hazard. Conversations with the Pasquotank, Currituck, Chowan, Camden (PCCC) Regional Health District have indicated a steady rise in the number of failing septic tank systems in the community. ' g. Alternatives Considered This section will discuss the different types of wastewater ' collection and treatment facilities and their advantages and disadvantages. Site selection for the treatment facilities is also discussed. 55 ' The proposed facilities for Camden Point consists of abandonment of the existing septic tank systems and the installation of a sewage collection system and sewage treatment facility. The collection and treatment facility will serve all existing residents that are in Camden Point. ' Several types of collection systems are evaluated which include gravity sewer mains, small diameter gravity (SDG) sewer system, and pressure sewer. ' Installation of the collection system will occur within the existing NC Department of Transportation rights -of -way and private roads in Camden Point. Standard encroachment agreement forms will be prepared for work within the NCDOT rights -of -way. Sewer ' mains to residents up private roads will follow the existing water main easement. Due to severe limitations related to location of treatment facilities, soil conditions, ' flooding potential and to the relatively long distance between residential areas, construction of gravity sewers was eliminated from further consideration. The collection system presented as most feasible consists of residential grinder pumps that pump to ' common force mains located along the roadside in Camden Point. The effluent will be pumped to a new treatment facility. ' Several sewage treatment facilities are presented for this project. Due to the proximity of Albemarle Sound in relationship to Camden Point, surface water discharge is evaluated. Types of surface water discharge systems considered are lagoons, oxidation ditches, ' mechanical plant, and constructed wetlands systems. Types of land application systems considered are lagoon systems with subsurface disposal and lagoon systems with spray irrigation systems onto agricultural crops or forested areas. ' Surface water discharge facilities would be ideally located in the center of Camden Point; however, discharge into the Albemarle Sound will be difficult to permit. Soil type is not a major consideration for the site location of a mechanical sewage treatment plant, except for foundation support for the facility. This type system would require approximately one acre of land. Lagoon systems would require approximately three acres of land near ' the sound. However, soils on Camden Point are unsuitable for lagoon construction due to wetness and seepage problems. Special construction measures such as a liner would be required for lagoons in this area. A mechanical treatment plant would be best located at ' the end of Texas Road with a discharge into the mouth of the Pasquotank River. Site selection for land application systems would depend on soil conditions. Preliminary ' site selection for spray fields or subsurface disposal can be evaluated based on soil suitability for septic tank absorption fields and lagoon systems. The most suitable soils within a feasibly distance of Camden Point consists of Bojac loamy sand located on 56 cultivated fields on the west side of Texas Road (SRI100). For these type systems, approximately 1 %Z acres of land would be required for the lagoons and twenty acres for ' the spray field to serve 53 hours. Location of spray fields selection is based on the availability of forested areas or agricultural areas. Local farmer participation is also considered. ' h. Selected Alternatives ' Collection System The Camden Point system was designed using grinder ' pumps. Grinder pumps come in one size for this system, which is 2 HP. For a system with 53 pump stations, research has indicated the maximum daily number of pumps operating simultaneously is nine. For the force main design, each run of force main was ' sized based on the maximum number of pumps that can be expected to run simultaneously. The grinder pump station typically comes assembled in a 4' diameter fiberglass basin. The STEP system was not considered further as new septic tanks would ' be required at each residence because the existing tanks will not meet current codes. On -off control of the pump stations is accomplished through a float system and control ' panel. The control panel will contain an on -off switch, audible horn and alarm light. In the case of a pump malfunction, the alarm will signal the homeowner to call the maintenance department for repairs. ' The homeowner can supply power supply for the pump. In some instances, negotiations have been held with the local Power Company to supply a service pole at each ' installation and charge the customer a base rate similar to that of a yard light. In the other situation, the control panel and pump can be wired to the homeowner's home circuit. The system can be operated from a 120-volt power supply. ' Design flow of the system is based on 269 gallon per day per user. Pump station cycle time is based on pumping rate and basin size. The force mains are designed to maintain a ' minimum 2-feet/second minimum velocity based on the number of pumps operating simultaneously. This information is obtained from pump curves and research data from pump manufacturers. For this type of system, the force mains are designed based on the ' number of pumps running simultaneously at 20 gpm each. 1 57 C Treatment Facilities General Treatment facilities for Camden Point were analyzed using lagoon systems, spray irrigation, subsurface land application, mechanical treatment facilities with surface water discharge, oxidation ditches, and wetlands. Each of these alternatives is discussed in the following sections. Sizing of the facilities is based on 269 gallons per day per residence, or a total of 15,000 gallons per day. A mechanical treatment facility would consist of a 0.015-MGD package type treatment facility using extended aeration and tertiary treatment. Primary treatment would consist '. of an equalization chamber, aeration chamber, a clarifier and sludge holding chamber. Basic designs consist of a donut configuration with the extended aeration tank and digestor around the parameter and the clarifier in the center. Tertiary treatment would consist of duplex filter beds, clearwell, and wastewater chamber. Disinfection would consist of chlorination/dechlorination. A mechanical plant and constructed wetlands were considered options for treatment to surface discharge. It may be possible to locate a constructed wetlands facility on ' agricultural land which was converted from wetlands prior to the 1976 Clean Water Management Act. The discharge could be through a natural wetland drainage way to the Pasquotank River. Land Application ' Pretreatment will be required prior to land application. In small communities, lagoons are usually the most practical forms of preapplication treatment and storage. They are relatively easy to operate, require minimal maintenance, ' are less expensive than many other types of treatment, and eliminate the need for separate facilities. Lagoon systems offer consistency, reliability, flexibility, ease of operation and maintenance, and low cost. Generally, lagoons are constructed with one to three cells. Typical applications are with two cells and will be utilized in the design analysis of this report. The first cell is designed as a facultative cell with a BOD loading of about 100- pounds/acre day. The water level in this cell is usually constant and can be controlled ' with an adjustable overflow weir. The final cell can be used for storage and flow equalization. ' Typical BOD5 for medium strength wastewater is 220 mg/1. Using the flow rate of 0.015 MGD, BOD strength of 220 mg/l, and a BOD loading rate for the lagoon of 100 pounds/acre day, the required size of the lagoon system is 0.275 acres. Additional 1 58 ' storage is required for periods when the spray fields cannot be applied to. For this system 30 days storage is provided. Utilizing a 0.275-acre lagoon with a maximum depth of 9.5' ' would provide 30 days of storage. Land application methods were analyzed using subsurface and surface application ' methods. It was quickly realized that subsurface application using nitrification fields was not feasible due to the length of drain tiles required. With an average loading rate of 0.3 gallons/day/square foot, a total of approximately 16,600 linear feet of 4" drain tile would be required at an estimated construction cost for the nitrification field alone of $830,000. Spray irrigation systems were next analyzed. ' The first step in designing the land treatment portion of the system is to select a hydraulic loading rate. The most suitable sites for land application treatment are in the areas of Bojac loamy sand. This soil has a permeability range from 6" to 20" per hour. Whenever ' a range of the permeability rate is given, the lower end of the range should be used for primary effluent, the mid -zone for pond effluent, and the upper portion of the range for secondary effluent. -, Site selection for the spray irrigation system is based on the Bojac series soils. The mid - zone permeability rate for the Bojac loamy sand series soils is 4"/hour. This is equal to a ' hydraulic loading rate of 9 cm/week or 3.5"/week. However, past experience and conversations with specialists have dictated that the maximum loading rate that should be used in this area is 0.5"/week, requiring 9.15 wetted acres for 53 hours. Including a 150' ' buffer zone around the fields, a total of 20 acres is necessary. The sizing of the spray application facilities includes capacity for rainfall that will collect in the lagoons and a 1- day rest period between applications to each field. ' Figure 16 illustrates the site location plan based on the Bojac Soil series. Grasses are the primary crops that can be grown on wastewater spray fields; however, the land may be I leased from a farmer to grow crops which are not consumed raw. Tables 18-21 illustrate cost summaries and projected rates based on 53 users and a Rural ' Center grant in which Camden County will have to finance 10% of the project cost with loan money. 1 59 H 03 boo TABLE 18 .

Recommended System Based on the above discussions it is recommended that a pressure sewage collection system using residential grinder pumps be installed with sewage being pumped to a new sewage lagoon and land application system for treatment. The pressure sewage collection system is chosen based on the low initial capital cost and ease of installation. A land application system was chosen for treatment based on its competitive construction costs with the other treatment facilities, low operation and maintenance costs, simplicity of operation and no -discharge to surface waters. ' A site evaluation has been performed by Dr. Bob Rubin of N.C. State University of the bojac soils ridge along Texas Road. It was determined there is a suitable area of soils approximately 300' wide by 2,500' long for a spray field. Based on the previously discussed hydraulic loading rates, this system will support up to a maximum of 75 residences. Therefore, any growth will be limited with this system. ' A consideration of Camden County is to upsize the system to allow a certain amount of future growth. However, this growth must also be controlled due to its environmental impacts to the area. Due to wetland restrictions, it may be feasible to establish a sewer service area consisting of the existing platted lots on the south side of Sailboat Road. Lots on the north side of Sailboat Road are separated from high ground by a large drainage canal and therefore are not buildable due to wetland restrictions. Therefore, the ' potential buildout of the sewer service area is 250 residences. Further investigations should be conducted with regulatory agencies regarding other potential treatment facilities such as mechanical plants with surface water discharges or constructed ' wetlands. 2. South Mills Sewer System ' This system would potentially provide service to 600-700 homes and businesses and anticipated new businesses in the South Mills Village. The sewer ' system would allow for commercial redevelopment in the historic canal village. The collection system would consist of a mix of gravity and pressure sewer collection systems located in the most populated areas of the Village. The treatment facility could be located near the existing water plant and discharged onto the Pasquotank River. Anticipated cost for the system is approximately $4 million. Funding could be through a mixture of USDA -Rural Development, Community Development Block Grant, Rural ' Economic Development Center, and local funds. More detailed analysis is required to determine the system layout and expected revenues and expenditures. L 1 65 V. CONCLUSIONS It was the intention of this study to present a growth management plan through the development of feasible water and sewer facilities. It is feasible to serve a major portion of the County with a rural water distribution system and construction of a water treatment facility. Key notes of the water system would be a ' large diameter trunk main along U.S. Highway 158 to serve the commercial/business development and a potential industrial park at Belcross. A large diameter trunk main is also needed along N.C. Highway 343 north of Camden Village and U.S. Highway 17 to Virginia to support the large potential of residential development in the northern portion of the County. ' Only a few areas in the County are feasible and have the need for a central sewer system. Most areas of the County can support continued growth with on -site septic tank systems. The Camden Village area and the U.S. Highway 158 corridor are restricted from growth and development due to unsuitable soils for septic tank systems. Installation of a central sewer in this area will allow desired business and commercial growth. The installation of a central sewer system in this area will allow desired business and commercial growth. The installation of a central sewer system in the Camden Point area is needed to eliminate an environmental health hazard due to failing sewer systems of the existing residences as well as to allow a controlled growth. Finally, South Mills Village has the population ' density to support a central sewer system if so desired. 1 66 L APPENDIX A ' RO WATER TREATMENT FACILITY DRAFT DISCHARGE PERMIT Hobbs, Upchurch &_ Associates, P.A. 1qj Consulting Engineers ' 2009 S.
