The river basin is located entirely within the state’s boundaries and flows southeast from the north central piedmont region near Greensboro to the Atlantic Ocean near Wilmington (Figure A-4). The Cape Fear River is formed at the confluence of the Haw and Deep Rivers on the border of Chatham and Lee counties, just below the B. Everett Jordan Reservoir dam. From there, the river flows across the coastal plain past Fayetteville through three locks and dams to Wilmington before entering the ocean. The Black and Northeast Cape Fear Rivers are blackwater rivers that meet the Cape Fear River in Brunswick County. The basin includes four coastal Outstanding Resource Waters (Stump, Middle, Topsail and Masonboro Sounds) and one inland ORW (a portion of the Black River). The most populated regions of the basin are in and near the Triad area (Greensboro-Burlington- High Point), the Durham-Chapel Hill area and Fayetteville. The overall population density is 160 persons per square mile compared to a statewide average of 139 persons per square mile. The percent population growth over the 7-year period from 1990 to 1997 was 13.2% compared to a statewide increase of 12.0%. Estimated water usage in the basin is expected to increase nearly 95% (193 MGD in 1992 to 376 MGD by 2020). Over one-half of the land in the river basin is forested. Statistics provided by the US Department of Agriculture, Natural Resources Conservation Service (NRCS), indicate that during the 10-year period from 1982 to 1992, there was a significant increase in the amount of developed land (43%). The basin contains 54% of the state’s swine operations, and swine populations in the basin have increased 90% between 1994 and 1998. There are many different aquatic ecosystems in the Cape Fear River basin that support a wide variety of commercial and recreational fisheries. Wetlands, estuaries, blackwater rivers and rocky streams support 30 endangered species in the basin.

The mainstem of the river is formed by the confluence of the Deep and Haw Rivers just downstream of the B. Everett Jordan Reservoir dam. The Deep River originates near High Point and the Haw River near Greensboro. The mainstem of the river flows in a southeasterly direction until it empties into the Atlantic Ocean at Cape Fear, south of Wilmington. The watershed is divided into 6 major hydrologic areas (8-digit hydrologic units) by the US Geologic Survey (USGS). These include the Haw River/Jordan Reservoir watershed, the Deep River, the upper Cape Fear, the Black River, the Northeast Cape Fear and the lower Cape Fear, and coastal waters. These major hydrologic areas are further subdivided by DWQ for management purposes into 24 subbasins (Figures A-5 to A-7) denoted by 6-digit numbers (03- 06-01 to 03-06-24). Table A-4 shows the breakdown of USGS hydrologic units and DWQ’s corresponding subbasins. Maps of DWQ’s subbasins are included in Section B of the basinwide plan. The Cape Fear River basin, which has a total land area of 9,322 square miles and 6,049 stream miles, has an average drainage area of 1.5 square miles per stream mile. A variety of aquatic systems are represented in the basin as the terrain changes from the piedmont to the coastal plain, including large freshwater rivers, blackwater swamps and estuaries.

The upper Cape Fear River basin is mostly in the piedmont, and the lower Cape Fear River basin lies in the coastal plain. The geology underlying the Cape Fear River basin has an affect on both stream water quality and water quantity. Ten low flow hydrologic areas (HA1-HA10) were defined for North Carolina by USGS (Figure A-8). Areas were defined by relating topography, geology, mean annual Section A: Chapter 2 – Basin Overview 17 runoff, and other features to low flow frequency characteristics including 7Q10 (annual minimum 7-day consecutive low flow, which on average, will be exceeded 9 out of 10 years) and 30Q2 (annual minimum 30-day consecutive low flow, which on average, will be exceeded in 1 out of 2 years). The ten HAs typically form a southwest-northeast band across the state and lie within three physiographic areas – the coastal plain, piedmont and mountains (Giese and Mason, 1993). In general, the lowest potential for sustaining base flow to streams is in the clay and sandy soils area of the coastal plain (HA1 And HA2) and the eastern and central piedmont (HA4, HA6, HA7 and HA8). The following discussion explains the characteristics that reduce the potential for base flow in these regions. Coastal Plain Physiographic Area The geology of this area consists of alternating layers of sand, silt, clay and limestone. This area was divided into three HAs based on soil types and topography. These are clay soils (HA1), sandy soils (HA2) and the Sand Hills (HA3). With the exception of the Sand Hills area (HA3), topographic relief is relatively flat, with the land surface dipping coastward at a rate of only a few feet per mile. Topographic relief and hydraulic gradient in the Sand Hills (HA3) is much higher. The clay soils have the lowest low flow values of the three HAs (median 7Q10 is 0[ft3/s]/mi2); sandy soils (HA2) have intermediate values (median 7Q10 is 0.006[ft3/s]/mi2); and the Sand Hills (HA3) have the highest values in the state (median 7Q10 is 0.318[ft3/s]/mi2). The low topographic relief of HA1 and HA2 (1 to 2 feet per mile) reflects the low hydraulic gradient and reduced potential to move water to streams than in areas with greater topographic relief (i.e., HA3). The lower low flow values for clay soils versus sandy soils result from the lower permeability of clay soils and that a higher percentage of precipitation that falls on clay soils is not absorbed and runs off directly into streams. Clay soils also have lower hydraulic conductivity than sandy soils, and thus, contribute less to base flow of streams than sandy soils. Eastern and Central Piedmont Physiographic Area Topography in this area is characterized by rolling hills and geologic formations consisting of crystalline or sedimentary rocks. This area was divided into six HAs based on soil types, topography and underlying bedrock type: the Eastern Slate Belt (HA4), the Raleigh Belt (HA5), the Triassic Basin (HA6), the Carolina Slate Belt (HA7 and HA8), and the Charlotte Belt and Milton Belt (HA9). Of particular interest within this area is the fact that the sedimentary rocks underlying the Triassic Basin have the lowest average yield of water to wells of all rock types in the state. This low yield implies the rocks have low permeability, and thus, result in low base flows of streams in the region. Section A: Chapter 2 – Basin Overview 18 The 7Q10 values for HA6 are zero for all but the largest drainages. In addition, the Carolina Slate Belt region is associated with low to zero flow streams. DWQ limits discharges of oxygen- consuming wastewater to these low base flow streams. In addition, the overall low permeability of residual soils derived from the Triassic sedimentary rocks results in low percolation rates for septic systems. This low permeability promotes surface runoff and shallow discharge during storm flow events. The goal of DWQ for streams determined to be zero flow streams is to remove all discharges, or if removal is not possible, advanced treatment will be required. DWQ management strategies for wastewater discharges into zero flow streams are presented in Section A, Part 4.12. 2.4 Land Cover Land cover information in this section is derived from the National Resources Inventory (NRI) of 1992 and 1982, as developed by the Natural Resources Conservation Service (USDA, 1994). The NRI is a multi-resource national inventory based on soils and other resource data collected at scientifically selected random sample sites. It is considered accurate to the 8-digit hydrologic unit scale established by the US Geological Survey (USDA, 1994). Table A-5 summarizes acreages and percentage of land cover from the 1992 NRI for the entire basin and for the major watershed areas within the basin (USGS hydrologic unit 03030001 is not included in the table because only a small portion of the area is within the Cape Fear River basin). Land cover types identified by the NRI as occurring in the Cape Fear River basin are presented in Table A-6. Land cover in the basin, as presented in Table A-5, is dominated by forestland that covers approximately 56% of the land area. Agriculture (including cultivated and uncultivated cropland and pastureland) covers approximately 24% of the area. The urban category comprises roughly 9% of the area and exhibited the most dramatic change since 1982, with a 43% increase of land area in this category. Other categories that showed substantial changes since 1982 were uncultivated cropland and "other" with increases of 18% and 17%, respectively. These land cover changes are summarized in Figure A-9. The most recent land cover information for the Cape Fear River basin is based on satellite imagery collected from the North Carolina Corporate Geographic Database. The state’s Center for Geographic Information and Analysis (CGIA) developed statewide land cover information based on this 1993-1995 satellite imagery. This land cover data is divided into 24 categories. For the purposes of this report, those categories have been condensed into five broader categories as described in Table A-7. Figure A-10 provides an illustration of the relative amount of land area that falls into each major cover type for the Cape Fear River basin.

Table A-8 presents census data for 1970, 1980 and 1990 for each of the subbasins. It also includes land areas and population densities (persons/square mile) by subbasin based on the land area (excludes open water) for each subbasin. Densely populated areas are scattered across the basin and include the Burlington-Greensboro-High Point area in the upper part of the basin (Figure A-11), the Fayetteville area in the middle part of the basin, and the Wilmington area in the lower portion of the basin (Figure A-12). The subbasin that encircles the Chapel Hill area is the most densely populated with 783 persons/square mile compared to a basinwide average of 160 persons/square mile. This density compares to a statewide average of 139 persons/square mile. It should be noted that some of the population figures are estimates because the census block group boundaries do not generally coincide with subbasin boundaries. The census data are collected within boundaries such as counties and municipalities. By contrast, the subbasin lines are drawn along natural drainage divides separating watersheds. Therefore, where a census block group straddles a subbasin line, an estimate has to be made on the percentage of the population that is located in the subbasin. This is done by simply determining the percentage of the census block group area located in the subbasin and then taking that same percentage of the total census block group population and assigning it the subbasin. Use of this method necessitates assuming that population density is evenly distributed throughout a census block group, which is not always the case. However, the level of error associated with this method is not expected to be significant for the purposes of this document. It is also important to note that the census block groups change every ten years, so comparisons between years must be considered approximate. Growth Trends The percentage increase in population for the entire basin was 29.3% from 1970-1990 and 11.5% from 1980-1990. This latter percentage is almost equal to a statewide increase of 12.7% over the same ten-year period. Population increases by subbasin are presented in Figure A-13 and Table 8. Table A-9 shows the estimated percent changes in growth between 1990 and 1997 and projected percent change in growth between 1997 and 2010 for counties in the basin (Office of State Planning, 1999). Since river basin boundaries do not coincide with county boundaries, these numbers are not directly applicable to the Cape Fear River basin. They are instead presented as an estimate of possible countywide population changes. Population growth trends for the basin between 1990 and 1997 indicate growth rates for six of the 26 counties of 20 to 30 percent and a basinwide population increase of nearly 13.2%. Projections for population growth from 1997 to 2010 indicate five counties with growth rates in excess of 30 percent and seven counties with growth rates of 20 to 30 percent with a total population increase in the basin of 17.8%.

Over half the total lakes are located in the upper portion of the basin (subbasins 03-06-01 through 03-06-08). These impoundments serve as water supplies for communities such as Greensboro, Burlington, Durham and Chapel Hill. Section A: Chapter 2 – Basin Overview 27 B. Everett Jordon Reservoir, located mostly in Chatham County south of Durham and west of Raleigh, is the largest lake in the basin and is used for water supply, flood control and recreation area in one of the fastest growing regions of the state. There are five natural lakes, (the Carolina Bays), in the lower portion of the basin. Carolina Bays are of unknown origin located along the East Coast. The lakes are between 30,000 and 100,000 years old and, because of the unique chemistry and productivity, are home to many endemic species. The lakes are shallow, fed by surface and shallow groundwater, and function as wetlands. Agricultural and forestry practices, prior to 1970, have left undisturbed only about 10 percent of these lakes (Krajick, 1997). 2.6.2 Fish and Shellfish Over 95 fish species have been found in the Cape Fear River basin including a variety with recreational and commercial importance. Popular sportfish species found in the freshwater portion of the river and reservoirs include largemouth bass, sunfish, crappie, catfish and pickerel. Recreationally and commercially important anadromous species, including striped bass, American and hickory shad and herring, migrate into freshwater portions of the Cape Fear River and tributaries to spawn during the spring. The Cape Fear River below Wilmington supports valuable recreational and commercial fisheries for striped bass, speckled sea trout, croaker, flounder and spot. Commercial finfish landings within the Cape Fear River basin have declined since 1996 from 108,764 pounds valued at $117,990 to 74,514 pounds valued at $64,191 (Figure A-14). Non-finfish commercial landings within the Cape Fear River basin include shrimp, blue crabs, squid, scallops and oysters. This fishery has had similar declines in recent years (Figure A-15). Figure A-16 shows shellfish growing areas in the Cape Fear River basin. A total of 30 endangered, threatened or special concern species, including fish, amphibians, mammals, crustaceans and mollusks, are listed by federal and state agencies for the Cape Fear River basin. Atlantic and shortnose sturgeon were once plentiful in the Cape Fear River, but the population levels for both species are currently at low levels, with the few remaining individuals located primarily in the lower Cape Fear and Brunswick Rivers. The last shortnose sturgeon to be captured in the Cape Fear River was collected in 1993 (Fisheries Management Plan for the Cape Fear River, March 1998).

Some are connected to streams; and others, such as low lying pine plantations and pocosins, are not. Over the years, however, approximately half of North Carolina’s wetlands have been lost to development, farming and forestry practices. Wetlands now only cover about 25 percent of the state’s land area. 200,000 400,000 600,000 800,000 1,000,000 1,200,000 1994 1995 1996 1997 1998 Year Po u n d s / D o l l a r V a l u e Shellfish Pounds Shellfish Value 0 50,000 100,000 150,000 1994 1995 1996 1997 1998 Year Po u n d s / D o l l a r V a l u e Finfish Pounds Finfish Value Section A: Chapter 2 – Basin Overview 30 Wetlands provide a variety of benefits to society and are very important in watershed planning because of the functions they perform. Wetlands provide important protection for flood prevention to protect property values; streambank stabilization to prevent erosion and downstream sedimentation; water purification and pollutant removal (especially for nitrogen and phosphorus); habitat for aquatic life and wildlife and endangered species protection. These values vary greatly with wetland type. Wetlands adjacent to intermittent and permanent streams are most important to protecting water quality in those streams, as well as downstream lakes and estuaries. However, wetlands located landward or away from streams also have important water storage capacity and pollutant removal potential. Wetland Fill Activities In 1989, the Environmental Management Commission passed a rule directing DWQ to review wetland fill using a review sequence of avoidance, minimization and mitigation of wetland fill. After extensive public review, the EMC passed rules, effective October 1, 1996, to restructure the 401 Water Quality Certification Program. These rules are not a new regulatory program since DWQ has issued approvals for wetland fill since the mid-1980s. The rules consider wetland values - whether or not the wetland is providing significant uses or whether the activity would remove or degrade uses. The rules also specify mitigation ratios, locations and types to make the mitigation process more predictable and certain for the regulated community. DWQ’s emphasis continues to be on water quality and the essential role that wetlands play in maintaining water quality. Table A-10 shows wetland fill activities by subbasin. Wetland Draining and Ditching Activities Ditching and draining of wetlands in North Carolina have been a restricted activity under oversight from both state and federal environmental regulations since the early 1990s. Generally, approvals have been required from DWQ and the United States Army Corps of Engineers (ACOE) for draining activities that impact one third of an acre or more of wetlands. A federal court ruling in June 1998 overturned the authority of the ACOE to require permitting for wetlands draining. This decision effectively removed regulatory review of draining unless dirt spoil from a ditch is dumped into jurisdictional wetlands. The State of North Carolina has since determined that wetland ditching and draining still fall under its authority and are an illegal activity if proper approval is not acquired. That authority applies when the hydrology or biology of the wetland is altered or the draining violates downstream water quality standards such as turbidity, salinity and dissolved oxygen. DWQ developed and began implementing the wetland draining policy on March 1, 1999. Wetland draining activities include both ditching and installation of ground pumping systems. Other activities also covered under this policy include pond construction in wetlands, filling of isolated wetlands, and off-site sediment erosion into wetlands.

The landowner will be given an opportunity to refute the finding. If DWQ determines that a violation has occurred, it can seek enforcement action and require that the natural hydrology or biology be restored. In some instances, the filling of ditches may require a federal 404 wetland fill permit. Ditch maintenance is allowed as long as written documentation can be provided on the ditch’s original height and width dimensions. Both DWQ and the Division of Land Resources will review such activities. Ditches created for forestry purposes are allowed if they are designed, constructed and maintained properly to retain the natural wetland hydrology. Refer to Best Management Practices for Forestry in the Wetlands of North Carolina. Section A: Chapter 2 – Basin Overview 32 DWQ has the authority to review specific wetland draining projects that began prior to March 1, 1999 to determine whether the draining activities impaired downstream water quality. The Division of Land Resources will check various projects to make sure they have complied with Sedimentation and Erosion Control Plans. The Department of Environment and Natural Resources is using a multiagency approach to implement the draining policy, to seek compliance and to pursue enforcement. Involved DENR agencies include DWQ, Division of Land Resources, Forest Resources, Soil and Water Conservation, and Coastal Management. The US Natural Resources Conservation Service will also participate. When violations are found, regulators can seek injunction relief to cease the draining activity and to restore the wetland on-site, civil penalties of up to $10,000 per day, and possible prosecution. The Division of Forest Resources is flying reconnaissance missions, with various regulatory personnel, to identify and assess draining sites. Satellite imagery is also used to target problem areas. To further assist in wetland protection, the public is encouraged to report possible sites where illegal draining has occurred. To report possible wetlands draining violations in the Cape Fear River basin, the public can contact the appropriate DWQ regional office: Fayetteville (910) 486-1541, Wilmington (910) 395-3900, Raleigh (919) 571-7400 and Winston-Salem (336) 771-4600. Wetland draining project acres and types are summarized in Table A-11. Figure A-17 shows the locations of project areas in the Cape Fear River basin.

The wetland data used in this analysis were developed by the Division of Coastal Management and are not intended to represent jurisdictional wetland boundaries. Section A: Chapter 2 – Basin Overview 34 There are several uses and limitations that should be considered when reviewing the wetland draining project data in the above tables. These include: 1. Project boundaries were compiled from NC Division of Land Resource’s permit file information, aerial surveys conducted by regional office staff, low altitude color infrared photography, and on-site investigations. These methods created inherent and varied inaccuracies in the data. 2. Project boundaries represent approximate size and location only; more precise information will require more extensive individual site visits. 3. Wetland data used in this analysis were obtained from NC Division of Coastal Management. For more information on mapping procedures and data accuracy, contact Jim Stanfill of the Division of Coastal Management at (919) 733-2293. 4. The numbers provided in this analysis represent potential wetland impacts, not actual wetland "loss". Wetland Restoration Efforts The North Carolina Wetlands Restoration Program (NCWRP) is responsible for implementing wetland and stream restoration projects on a basinwide scale throughout the state. The focus of the program is to enhance water quality, flood prevention, fisheries, wildlife habitat and recreational opportunities. The NCWRP is not a grant program. However, it can compliment grant programs like the Section 319 program by taking on restoration projects identified through Section 319 grant applications. Alternatively, studies funded by Section 319 to identify suitable stream or wetland restoration sites can then be implemented by the NCWRP. The NCWRP can also directly fund other stream or wetland restoration sites provided those sites are located within a priority subbasin, as determined by the NCWRP. Finally, the NCWRP can perform restoration projects cooperatively with other state or federal programs or with environmental groups. The NCWRP has identified priority subbasins for the Cape Fear River basin through the Basinwide Wetlands and Riparian Restoration Plan for the Cape Fear River Basin. For more information on this document or the NCWRP, call (919) 733-5208 or visit http://h2o.enr.state.nc.us/wrp/index.htm. 2.7 Permitted Wastewater and Stormwater Discharge Facilities Discharges that enter surface waters through a pipe, ditch or other well-defined point of discharge are broadly referred to as 'point sources'. Wastewater point source discharges include municipal (city and county) and industrial wastewater treatment plants and small domestic wastewater treatment systems serving schools, commercial offices, residential subdivisions and individual homes. Stormwater point source discharges include stormwater collection systems for municipalities and stormwater discharges associated with certain industrial activities. Point source dischargers in North Carolina must apply for and obtain a National The primary pollutants associated with point source discharges are: * oxygen-consuming wastes, *nutrients, * color, and * toxic substances including chlorine, ammonia and metals Section A: Chapter 2 – Basin Overview 35 Pollutant Discharge Elimination System (NPDES) permit. Discharge permits are issued under the NPDES program, delegated to DWQ by the Environmental Protection Agency. 2.7.1 Wastewater Discharges in the Cape Fear River Basin There are 280 permitted wastewater discharges in the Cape Fear River basin. Table A-12 provides summary information (numbers of facilities and permitted flows) regarding the discharges by type and subbasin. The various types of dischargers characterized in the table are described in the inset box. A summary of all dischargers can be found in Appendix I. Figures A-18, A-19 and A-20 show the location of major and minor permitted wastewater discharges within the basin. The number of triangles on the map depicting major discharges do not correspond exactly to the number of major facilities listed in Table A-12, since some major facilities have more than one outfall point. Each outfall point received its own triangle. 2.7.2 Stormwater Discharges in the Cape Fear River Basin Amendments to the Clean Water Act in 1990 provided requirements for NPDES stormwater permits for municipal, industrial and construction activities (Phase I of the NPDES stormwater program). Permit requirements were established for ten categories of industrial activity ranging from vehicle maintenance facilities to textile manufacturers. Permit requirements were also established for construction activities which disturb 5 or more acres of land area. Permit application requirements were established for municipalities with a population of 100,000 or more. The focus of the NPDES stormwater program is pollution prevention and source control. The primary concern with runoff from industrial facilities is the contamination of stormwater from contact with exposed materials. In addition, poor housekeeping can lead to significant contributions of sediment and other water quality pollutants. To address these issues, each NPDES stormwater permitted facility must develop a Stormwater Pollution Prevention Plan (SPPP) that addresses the facility’s potential impacts on water quality. Facilities or activities identified as having significant potential to impact water quality are also required to perform analytical monitoring to characterize the pollutants in their stormwater discharges under individual NPDES stormwater permits. Types of Wastewater Discharges Major Facilities: Municipal Wastewater Treatment Plants with flows ≥1 MGD (million gallons per day); and some industrial facilities (depending on flow and potential impacts on public health and water quality). Minor Facilities: Any facilities not meeting the definition of Major. 100% Domestic Waste: Facilities that only treat domestic-type waste (water from bathrooms, sinks, washers). Municipal Facilities: Facilities that serve a municipality. Can treat waste from homes and industries. Industrial Facilities: Facilities with wastewater from industrial processes such as textiles, mining, seafood processing, glass-making and power generation. Other Facilities: This category includes a variety of facilities such as schools, nursing homes, groundwater remediation projects, water treatment plants and non- process industrial wastewater.

Phase II – November 1999 Requires a NPDES permit for municipal storm sewer systems serving populations under 100,000 that are located in urbanized areas. Provides incentives to industrial facilities covered under Phase I for protecting operations from stormwater exposure. Requires a NPDES stormwater permit for construction sites that are 1-5 acres. Permits are granted in the form of general stormwater permits (covering a wide variety of activities) or individual stormwater permits. Excluding construction general permits, there are 623 general stormwater permits and 48 individual stormwater permits issued within the river basin. Individual permit holders are presented in Table A-13. The municipalities covered by the NPDES stormwater regulations are called Municipal Separate Storm Sewer Systems (MS4s). Phase I covers large and medium MS4s (population of 100,000 or more). There are six permitted Phase I MS4s in North Carolina. The cities of Greensboro, Durham and Fayetteville (which also includes Cumberland County) are the only Phase I MS4s in the Cape Fear River Basin. On October 29, 1999, a second phase of the NPDES stormwater program was signed into law. Phase II lowers the construction activity threshold to 1 or more acres of land disturbance and allows a permitting exemption for industrial facilities that do not have significant materials or activities exposed to stormwater. Phase II also pulls many small local governments into the NPDES stormwater program. The federal regulations require that small MS4s with a population of 50,000 or more and a density of 1,000 people per square mile be covered under a NPDES stormwater permit. This includes small municipalities that, when clustered together, are considered an urbanized area that collectively meets the 50,000/1,000 criteria. In addition, DWQ is required to develop designation criteria that pull in other small MS4s. The designation criteria must include, at a minimum, all MS4s with a population of 10,000 or more and a density of 1,000 people per square mile. At a minimum, the local governments listed in Table A-14 will be covered under Phase II of the NPDES stormwater program. It is highly likely that additional local governments will be required to seek a permit through designation. Phase II MS4 permit applications must be submitted to DWQ by March 1, 2003.

These numbers reflect only operations required by law to be registered, and therefore, do not represent the total number of animals in each subbasin. Figures A-21, A-22 and A-23 show the general location of the registered operations in the basin. Steady State Live Weight (SSLW) is the result, in pounds, after a conversion factor has been applied to the number (head count) of swine, cattle or poultry on a farm. The conversion factors, which come from the Natural Resource Conservation Service (NRCS) guidelines, vary depending on the type of animals on the farm and the type of operation (for example, there are five types of hog farms). Since the amount of waste produced varies by hog size, SSLW is the best way to compare the sizes of the farms. The NC Department of Agriculture provided information on animal capacity by subbasin (Table A-16). Section A: Chapter 2 – Basin Overview 43 Key Animal Operation Legislation (1995-1999) 1995 –Senate Bill 974 requires owners of swine facilities with 250 or more animals to hire a certified operator. Operators are required to attend a six-hour training course and pass an examination for certification. Senate Bill 1080 established buffer requirements for swine houses, lagoons and land application areas for farms sited after October 1, 1995. 1996 – Senate Bill 1217 required all facilities (above threshold populations) to obtain coverage under a general permit, beginning in January 1997, for all new and expanding facilities. DWQ was directed to conduct annual inspections of all animal waste management facilities. Poultry facilities with 30,000+ birds and a liquid waste management system were required to hire a certified operator by January 1997 and facilities with dry litter animal waste management systems were required to develop an animal waste management plan by January 1998. The plan must address three specific items: 1) periodic testing of soils where waste is applied; 2) development of waste utilization plans; and 3) completion and maintenance of records on-site for three years. Additionally, anyone wishing to construct a new, or expand an existing, swine farm must notify all adjoining property owners. 1997 –House Bill 515 placed a moratorium on new or existing swine farm operations and allows counties to adopt zoning ordinances for swine farms with a design capacity of 600,000 pounds (SSLW) or more. In addition, owners of potential new and expanding operations are required to notify the county (manager or chair of commission) and local health department, as well as adjoining landowners. DENR was required to develop and adopt economically feasible odor control standards by March 1, 1999. 1998 –House Bill 1480 extended the moratorium on construction or expansion of swine farms. The bill also requires owners of swine operations to register with DWQ any contractual relationship with an integrator. 1999 –House Bill 1160 extended (again) the moratorium on new construction or expansion of swine farms, required DENR to develop an inventory of inactive lagoons, and requires owners/operators of an animal waste treatment system to notify the public in the event of a discharge to surface waters of the state of 1,000 gallons or more of untreated wastewater.

Under this statute all units of local government that provide or plan to provide public water supply service are required to prepare a Local Water Supply Plan (LWSP) and to update that plan at least every five years. The information presented in a LWSP is an assessment of a water system’s present and future water needs and its ability to meet those needs. The current LWSPs are based on 1992 data. Updated plans based on 1997 water supply and water use information were completed in 1999. In 1992, 130 systems that use water from the Cape Fear River basin provided an average of 208.77 million gallons per day (MGD) to 1.3 million people (Table A-17). Projections of future need show that these systems expect their service populations to increase by 66% to 2.1 million people by 2020. Average daily water use for these systems is expected to increase by 86 percent to 388 MGD by the year 2020. These data only represent systems submitting a LWSP and do not reflect the needs of the public water systems in this basin that are not required to prepare a plan because they are not operated by a unit of local government. The information is self- reported and has not been field verified. However, plans have been reviewed by staff engineers for consistency and reasonableness. More information is available for these and other systems across the state that submitted a Local Water Supply Plan from the Division of Water Resources’ website at: www.dwr.ehnr.state.nc.us/home.htm. 2.9.2 Minimum Streamflow One of the purposes of the Dam Safety Law is to ensure maintenance of minimum streamflows below dams. Hydropower dams that are subject to FERC authority are exempt from Division of Land Resources (DLR) authority. Conditions may be placed on dam operations specifying mandatory minimum releases in order to maintain adequate quantity and quality of water in the length of a stream affected by an impoundment. Table A-18 lists hydroelectric projects with minimum releases. The Division of Water Resources (DWR), in conjunction with the Wildlife Resources Commission, recommends conditions relating to release of flows to satisfy minimum instream flow requirements. The permits are issued by the Division of Land Resources. Table A-19 lists minimum instream flow studies in this basin.

Section A: Chapter 2 – Basin Overview 52 Table A-19 Minimum Instream Flow Studies in the Cape Fear River Basin WATER SUPPLY IMPOUNDMENTS/WITHDRAWALS Dam Study Cooperators Purpose of Study Big Alamance Creek DWR The Town of Burlington’s water supply, Lake Mackintosh, has a tiered release with a maximum flow release of 9 cfs at full pool. The recommendation was based on a wetted perimeter study done by DWR. Back Creek DWR DWR requested, following the review of the environmental assessment for the expansion of the Graham-Mebane water treatment plant from 6 to 12 MGD, a tiered release with a maximum low flow release of 5 cfs at full pool from Graham-Mebane Lake. The flow recommendation was based on a wetted perimeter study by DWR. Bones Creek DWR and NCWRC Lake Rim is used by the NC Wildlife Resources Commission as a fish hatchery storage pond. DWR requested a minimum flow as a stipulation for dam repair. The Division assisted the Commission in determining a tiered release of 18 cfs from the impoundment in all months except July, when the release is 10.5 cfs. The releases are based on a hydrologic desktop investigation. A calibrated gage is required to monitor releases. Branson Creek NCWRC A stipulation for repairs to Forest Lake dam in Fayetteville was a minimum flow requirement of 3.4 cfs. The recommendation is based on a NC Wildlife Resources Commission habitat evaluation and a hydrologic desktop investigation. Little Cross Creek DWR, NCWRC and DWQ DWR participated in an aquatic habitat assessment of Little Cross Creek below Glenville Lake (Fayetteville’s reserve water source) with the NC Wildlife Resources Commission and DWQ. A minimum flow of 3.6 cfs, based on a hydrologic desktop investigation, was established. Deep River DWR The proposed Randleman reservoir will serve the cities of Greensboro and High Point. The reservoir will have a tiered minimum release ranging from a high of 30 cfs at full pool, 20 cfs when below 60 percent full pool, and 10 cfs when below 30 percent full pool. The minimum flow recommendations are based on a wetted perimeter study. The project will divert up to 30.5 MGD (47.1 cfs) which will reduce the average annual flow. The natural low flows in the lower Deep River will be increased by the minimum release. There will be some interbasin transfer (see Part 2.9.3). Randleman Reservoir will impact hydropower generation in the Deep River. The Coltrane Mill project will be inundated by the impoundment. DWR estimates that hydropower generation will be reduced by 5 to 15 percent depending on the amount of withdrawal from the reservoir, proximity of the generation facility to Randleman, and the minimum flow requirement at each project. The City of High Point’s primary sources for water, High Point City Lake and Oak Hollow Reservoir, do not have minimum release requirements. The Dam Safety Law restricts minimum flow requirements for existing reservoirs to 10 percent of the safe yield. This corresponds to 1.3 cfs and 1.9 cfs for High Point City Lake and Oak Hollow Reservoir, respectively. Mill Creek NCWRC Reservoir Park dam in Southern Pines has a minimum flow requirement of 0.5 cfs based upon consultation with the NC Wildlife Resources Commission and a hydrologic desktop investigation. Nick’s Creek DWR and Town of Carthage DWR will be cooperating with the Town of Carthage on an instream flow study of Nick’s Creek to evaluate a proposal to expand their withdrawal from 0.5 to 1.0 MGD. Reedy Fork DWR Lake Townsend in Greensboro has a minimum flow requirement of 7.1 cfs at full pool as a stipulation for expansion of the water treatment plant from 20 to 30 MGD. The recommended flow is based upon a wetted perimeter study done by DWR. Rocky River DWR, Town of Siler City and other agencies The Town of Siler City has a tiered release at their water withdrawal structure based on an instream flow study performed by DWR. The minimum release from December through May is 3.5 cfs when the town’s reservoir is at 40 percent capacity or greater. The town has installed gages to monitor the release. DWR and other resource agencies are now participating in discussions with the town on a proposal to raise the evaluation of the withdrawal pond by 12. 5 feet. Section A: Chapter 2 – Basin Overview 53 2.9.3 Interbasin Transfer Water users in North Carolina are required to register their water withdrawals and transfers with the Division of Water Resources if the amount is 100,000 gallons per day or more, according to NCGS §143-215.22H. In addition, transfers of one million gallons per day or more require certification from the Environmental Management Commission, according to NCGS §143- 215.22I. Table A-20 lists the parties that have registered withdrawals in the Cape Fear River basin as of January 1, 1999. The river basin boundaries that apply to these requirements are designated on a map entitled Major River Basins and Subbasins in North Carolina that was filed in the Office of the Secretary of State on April 16, 1991. Within the Cape Fear basin, six subbasins are delineated: the Haw River, the Deep River, the Cape Fear River, the South River, Northeast Cape Fear River and the New River (Figure A-24). (Note: The New River is not considered part of the Cape Fear River basin under the basinwide management approach which utilizes basin definitions adopted by the Department of Water and Air Resources in 1974. The New River will be addressed as part of the White Oak River Basinwide Water Quality Plan in 2001.) Figure A-25 shows the approximate location of transfers of 1.0 MGD or greater. Table A-21 lists all potential transfers within the basin. Unless otherwise noted, the transfer amounts are 1992 average daily amounts in million gallons per day (MGD) based on Local Water Supply Plans and registered withdrawal/transfer information. Many of the transfers cannot be quantified due to undocumented consumptive losses (examples: septic, lawn irrigation). Note: Under a provision of Senate Bill 1299 (ratified by the General Assembly on September 23, 1988), all local water systems are now required to report existing and anticipated interbasin transfers as part of the Local Water Supply Planning process. This information will be available for future updates of this management plan and will allow an assessment of cumulative impacts. Currently, there are two permitted transfers in the Cape Fear basin. The first permit is for Cary/Apex’s 16 MGD transfer from the Haw River subbasin to the Neuse River subbasin. Cary and Apex are currently preparing environmental documentation to support an application for increasing the transfer amount. The second permit is for Piedmont Triad Water Authority’s 30.5 MGD transfer from the Deep River subbasin to the Haw and Yadkin River subbasins. This permit covers anticipated transfers resulting from the operation of the proposed Randleman dam. Other large transfers in the Cape Fear basin include Durham (18.0 MGD), Asheboro (4.7 MGD), and High Point (3.5 MGD).
