Stewart Land Design Engineering Services, Inc. 1700 East Boulevard Charlotte, NC 28203 Subject: NPDES Permit Application NPDES Permit No. NCO077453 Crescent Land and Timber Lincoln County Dear Mr. Stewart: In accordance with your request received November 27, 1989, the Division of Environmental Management (DEM) is returning your NPDES Permit application. A copy of your application has been submitted to our Central Files for future reference. Should you desire to reactivate your permit request, please advise the Division of Environmental Management in writing and resubmit the complete application with the appropriate application processing fees. Please note that construction or operation of wastewater discharge facilities without a permit may be considered a violation of the Division of Environmental Management regulation 15 NCAC 2H .0101 and the North Carolina General Statutes (GS 143-215.1). If you have any questions, please contact Mr. Dale Overcash at (919) 733-5083. cc: ce r. Trevor Clements Mr. Jim Patrick, EPA Mrs. Joyce O'Connell Sincerely, Don Safrit, Supe Permits and Engt C.

WWTP (NC0074012), which will be expanding to 0.500 MGD. With regard to Crescent Land and Timber's long-term wastewater treatment needs, we recommend that the applicant participate in the design and development of a 5.0 MGD regional WWTP being considered for the Lincoln County and Catawba County residents. Based on conversations with Mike Parker of the Mooresville Regional Office, Mr. Tom Cox, Engineering Consultant for Lincoln County, and a review of a map showing the proposed service area for this regional facility, it would appear that a lift station will be constructed within a mile of Crescent's proposed WWTP site. These preliminary engineering plans indicate that a 6" force main extending from this lift station would cross the lower portion of Crescent's property. Therefore, we concur with the opinion of the Mooresville Regional Office that it would be better environmentally for Crescent Land and Timber to connect with the proposed Lincoln County facility rather than discharge their waste directly into Lake Norman. If there are any questions concerning this matter, please contact me. cc: Steve Tedder Dennis Ramsey Rex Gleason Tom Cox Dale Stewart FIr MEMORANDUM TO: THRU: FROM: SUBJECT: DIVISION OF ENVIRONMENTAL MANAGEMENT October 17, 1989 Dale Overcash Trevor Clemente Thomas Stockton Jackie Nowelld� Return of Wasteload Allocation for Proposed Crescent Land and Timber - Lake Norman NPDES Permit No. NCO077453 The Technical Support Branch is returning the wasteload allocation submitted for the subject facility pending further investigation by the applicant concerning the feasibility of a tie-in with the existing Lin- coln Co.

PART IV - EVALUATION AND RECOMMENDATIONS Crescent Land and Timber Corporation proposes to develop an 825 acre tract for single family residential housing in eastern Page Three Lincoln County. The proposed development will initially involve approximately 0.300 MGD of the project flow, with the remaining 0.600 MGD coming from future service to neighboring properties. The applicant's engineer projects the WWT facility to be built in 0.300 MGD phases until capacity is reached. The site appeared suitable for WWTP construction provided all applicable buffers as noted in NCAC 0.0200 are met. The staff of this Office, however, recommends that this NPDES Permit request be denied for the following reason. Lincoln County currently has under construction a 0.100 MGD regional WWT facility (NC 0074012) approximately 5 1/2 miles from the Crescent site and has a proposed sewer outfall line passing less than one-half mile from Crescent's property. The Lincoln County facility has requested approval to expand to 0.500 MGD (a request is currently being processed by DEM) and approval is anticipated. Furthermore, a larger regional WWT facility, ultimately serving southern Catawba County, eastern Lincoln County, and possibly northeastern Gaston County with a design flow of 5.0 MGD is being proposed at a site below the existing regional WWTP. According to Crescent's engineer, this development is not expected to begin for at least two (2) years by which time capacity and sewer availability from the Lincoln County Regional Facility would be in place. Therefore, it is recommended that an NPDES Permit not be issued because a viable WWT alternative is available to serve this proposed development based on the projected construction schedule. If an NPDES Permit is issued, it is recommended that effluent requirements as have recently been recommended for discharges into Lake Wylie (BPJ) be applicable in order to reduce the potential occurrence to eutrophic conditions in Lake Norman. These limitations are as follows: BOD5 NH as N D.8. 15 mg/l 4 mg/l 5 mg/1 Concurrence with DHS is required prior to Permit issuance.

PROJECT OVERVIEW Crescent Land and Timber Corporation, Charlotte, North Carolina proposes to develop a planned residential community in Lincoln County. The project site is approximately 825 acres. The following preliminary report has been prepared to convey the proposed basis for water and sewer service to the development. B. REGULATIONS In. addition to compliance with laws, rules and regulations as required by the State of North Carolina Mecklenburg County, all utility work must comply with the following specific regulations as applicable to the nature of the work proposed: 1. North Carolina Administrative Code Title 15 Department of Natural Resources and Community Development Chapter 2 Environmental Management Sub -Chapter 2C Well Construction Standards. (Latest Revision) 2. Rules governing public water supplies Section .0600 through Service Sanitary Engineering Sub -Chapter 10D, Water Supplies. (Latest Revision) 3. North Carolina Administrative Code Title 15 Department of Natural Resources and Community Development Chapter 2 Environmental Management Sub -Chapter 2H Procedure for Permits. Approvals Section .0100 Wastewater Discharge to the Surface Waters. (Latest Revision) II - PROPOSED DEVELOPMENT A. PROJECT LOCATION The site of the proposed development is located along North Carolina Highway 16 on Webb's Chapel Road (SR1379) in Lincoln County. A vicinity map is attached as Figure 1. The site has portions which lie along SR1378, and SR1376 and is bordered by Lake Norman. B. DEVELOPMENT DESCRIPTION The proposed development will consist of residential housing. C. PHYSICAL FEATURES The project site is representative of piedmont North Carolina with medium to steep hills falling to the lake shoreline, the most significant physical feature. The site is predominately wooded with numerous small drainage ways leading to Lake Norman. The land is marked with moderate to steep slopes with the exception of a few areas immediately adjacent to drainage features where slopes become severe in some areas (greater than 15%). A reproduction of a portion of the U. S. Geological Survey Quadrangle Map covering the site is attached as Figure 2. A reproduction of the Soil Conservation Service soils map for the site is attached as Figure 3. Soils on the site vary as shown on the soils survey. The soils are predominarely cecil and pacolet series. The Cecil series dominates the ridges which the. less suitable pacolet soils are found along the natural drainage ways. It is estimated that approximately 25% of the site has pacolet characteristics which typically do not represent suitable soils for drainf field installations. III. WASTEWATER PARAMETERS A. DESCRIPTION OF WASTE The proposed development as described in Section II will be comprised of residential housing. Only domestic wastewaters will be generated. No industrial use will be allowed. It is anticipated that the wastewaters generated from general household and sanitary use and will exhibit characteristics typical of domestic sewage a follows: PARAMETER Five Day Bio-Chemical Total Suspended Solids Ammonia Nitrogen Chemical Oxygen Demand Grease Temperature (Approx.) pH CONCENTRATION Oxygen Demand 200 mg/1 250 mg/1 25 mg/1 500 mg/1 100 mg/1 50 degrees F (Winter) 65 degrees F (Summer) 6.5 - 9 B. PROJECTED WASTEWATER FLOWS A flow allowance of 360 gallons per day per residence is proposed as the basis for projection of community total, based on an average of 120 gallons per day per bedroom. The proportion of the projected flow attributable to our site is approximately 300,000 gpd while the remaining 600,000 volume is requested for possible future service to neighboring properties. C. TREATABILITY OF WASTE As the characteristic of the waste are expected to be typical of domestic sewage, the waste will be treatable using conventional waste treatment technology, i. e. biological and physical removal of waste contaminants. IV. WASTEWATER DISPOSAL ALTERNATIVES A. PUBLIC UTILITIES The proposed development is located entirely outside the corporate limits of all local utility facilities installed in the general vicinity. There are no plans currently underway for any extension to the project area. Although the private Governor's Island Treatment Plant has recently been installed nearby there is no excess capacity to handle this proposed project. B. INDIVIDUAL ON -SITE FACILITIES The alternative exists for on -site water and sewer facilities assuming the development plans were to allow for approximately 3/4 acre lots for individual wells and septic tank/drainfields. The development would be reduced significantly on this basis. A review of the soils maps indicate that an extensive proportion of the property may encounter difficulty supporting drainfield disposal due to shallow soils, poor soils, excessive slopes and ground water levels near the lake. An extensive detailed soils investigation has not ben performed. Based on experience and comparison with similar land tracts, it is likely that Health Department approval for subsurface disposal would be withheld for a significant proportion of the site. C. SPRAY IRRIGATION The site is split into four general areas by topographic features and SR1376. Due to the segmenting of the site, general severity of slopes, proximity to the lake water, and proposed development density the use of spray irrigation was not deemed a viable alternative based on preliminary economic and site evaluations. D. PRIVATE UTILITIES A third alternative for utilities service is a central water supply and sewage collection and treatment system owned and operated by a licensed private utility company. This approach would provide for water supply from several deep wells and central storage and distribution. Wastewaters would be collected and transported via a central system to a waste treatment plant serving the entire project. E. PROPOSED FACILITIES It is proposed that of the three alternatives,' a private utility be chosen and become the basis for development of the property to allow for the lands highest and best use. This would also support a viable - stable neighborhood, maximize flexibility and assure protected ground and surface water supplies and provide a responsible vehicle for service to the eventual homeowners. Although public facilities may eventually be extended to the property, the timing of such extensions is unknown and the immediate cost is prohibitively expensive to the developing company and consequently to,the ultimate home buyer. It is recommended however, that all facilities be designed and built so as' to minimize the difficulty in the integration of these facilities into a public system when such extension becomes feasible. The use of intensive single family septic tanks for the property is not recommended even at lower densities. The potential for pollution of ground water and surface water would be significantly increased with the extensive use of sub surface disposal over the tract. Private facilities, including a private waste treatment plant are recommended on the basis that they will allow more control over potential pollution in that treatment efficiencies can be monitored and corrective action taken whenever necessary; whereas septic tank failures may not be immediately detected. Repair of drainfield failures frequently simply move problems to the "reserve area" included with the original design, and if so, then leaves the homeowner with no other method of treatment when the available lot area for disposal is depleted. V. PROPOSED DISCHARGE A. RECEIVING WATERS Based on a development plan utilizing a private utility and treatment plant a National Pollutant Discharge Elimination System (NPDES) Permit for discharge of treated effluent to Lake Norman has been prepared. During the permit application period, the NC Division of Environmental Management will prepare a "Waste Load Allocation". The purpose of the waste load allocation is to generate, based on the characteristics and intended use of the receiving stream, a set of effluent standards to be included in the NPDES permit. A 'part of the allocation procedure is the generation of stream flow data by the US Geological Survey for the specific discharge point on Lake Norman. The resultant required treatment limits established by the waste load. allocation process are dependent on the stream flow thus determined by U.S.G.S., the physical characteristics of the stream, and the stream's classification of use by NCDEM. Lake Norman is classified for potable and recreational uses and design of all facilities will be based upon the preservation of the water quality of the Lake. B. IMPACT OF PROPOSED DISCHARGE The intent of the NPDES permitting process is to protect the receiving stream while simultaneously allowing discharge of treated wastewaters for various land use including residential development. The waste load allocation described above establishes a degree of treatment required by the proposed plant to minimize impact to the stream and allow for it's continued present use. The allocation basis for stream flow is dependent on statistical low flow figures to maintain stream quality during low flow periods. Thus, in general, the lower the stream flow observed during drought periods, the higher the degree of treatment required. In instances of extreme low stream flows, application for permit is denied. The extent of the body of water comprising Lake Norman and size of the drainage basin above the point of proposed discharge is sufficiently large that it is anticipated that secondary treatment standards will be proposed. The following sections describe, in more detail the facilities proposed. It should be noted that although the NPDES permit now applied for allows for the discharge of treated effluent, and "Authorization to Construct" must be obtained prior to construction and detailed plans and specifications must be approved by NCDEM to obtain the Authorization. VI. WASTEWATER TREATMENT FACILITIES A. PROPOSED TREATMENT PROCESS Due to the necessity of protecting the Lake Water Quality for drinking water and recreational uses, the proposed treatment plant will include several treatment processes. A Treatment Process Flow Schematic is presented as Figure 5. The primary treatment process will be biological assimilation of the domestic wastewaters under aerobic (in the presence of oxygen) conditions to eleminate sewage odors. It is anticipated that the development will occur in phases as market demand dictates. It is necessary for proper operation that the treatment facilities also be.phased. This construction phasing allows for a better matching of plant capacity with sewage flows and increased long term flexibility of operation. B. DESCRIPTION OF PROPOSED TREATMENT FACILITIES B-1 General The proposed treatment plant will include multi -stage treatment of domestic wastewaters generated from the subdivision. Construction of the plant will occur in phases providing an eventual multiple path treatment train for increased operational flexibility. Plant component processes are shown on the Process Flow Schematic (Figure 4) and a Preliminary Basis of Design is included as Appendix A. B-2 General Based on preliminary site evaluation of topography an influent pumping station will be required to "lift" wastewaters from the elevation of the influent gravity sewer line into the elevation above the 100 year flood level. The station will be equipped with dual pumps for back-up capability in the event of a pump failure. Controls will provide audible and visual alarms for pump failure to alert operators. B-3 Flow Diversion Station Following the influent pump station, a flow diversion system will be installed to allow splitting of flows as additional plant phases are constructed and to provide the plant operating staff flexibility in control of flows during repairs or maintenance. B-4 Flow Equalization It is anticipated that flows will be received at the plant with typical diurnal variations which tend to create peaks or surges during high use periods i.e. early mornings and around the dinner hour. To eliminate the impact of these surges on the plant and maintain average flow conditions, a flow equalization basin will be installed. Dual pumps will feed the main plant from the equalization basin at a constant rate equal to average flow. The level in the equalization basin will thus vary, increasing during peak flow periods and.falling during lower flow periods. Pump controls will be equipped with high level alarm to signal any pump failure. B-5 Aeration and Settling The primary component of treatment for the plant will be the main aeration basins followed by the Settling Tanks. Although these processes, aeration and settling, occur in separate basins or tanks, they operate together to accomplish the principle treatment step in the plant. In the aeration basin, wastewaters are retained for a minimum of twenty four hours, mixed, and combined with large volumes of air from the aeration blowers, to allow naturally occurring bacteria to assimilate the waste. The operator will be provided facilities to vary the amount of air and mixing and the volume of activated sludge recycle. Sludge recycle referes to the process whereby solids containing "activated" or acclimated bacteria are returned to the aeration basin from the settling tanks. In the settling tanks, a quiesient area, solids in the treated wastewaters are allowed to settle and out clarified liquid passes to the next treatment step. Settled solids are either pumped to the aeration basin to enhance and control the treatment or are wasted to a sludge digestion tank, where it is aerated and stored until taken off -site for ultimate disposal. B-6 Chlorination Disinfection Following aeration and settling, the clarified effluent will flow into a disinfection tank where chlorine will be added to kill any deliterious bacteria. A minimum of thirty minutes detention will be provided to allow "contact" time for reaction of the chlorine with the waste flow. B-7 Dual Media Filtration The next treatment step will provide dual media (sand and anthracite) filtration to filter out any suspended solids not captured in the settling tanks. This step will assure production of an effluent with minimal waste solids. Also in the event ofa plant upset in the aeration basins after capture on the filters to regenerate the treatment process and protect the plant against discharge of partially treated wastewater. Backwash pumping facilities will be provided with automatic controls and alarms to automatically backwash and clean the filters at the appropriate time. Solids captured on the filters will be returned to the treatment process via the equalization basin to prevent surging of the aeration basin. B-8 Post Aeration Following filtration the effluent will flow through additional tankage providing approximately 15 minute retention and aerated to elevate the dissolved oxygen level of the effluent and dissipate excess chlorine from the disinfection process. Elevating the dissolved oxygen content will help to assure that the treated effluent places no advserse impact on the receiving stream. B-9 Effluent Flow Measurement and Sampling The final components in the plant will include flow measurement to assure that the plant is not hydraulically overloaded and assist the operator in diversion of flows. A sampling station will provide a permanent access for sampling of effluent for testing purposes to assure the plant is meeting it's permit requirements. B-10 Sludge Holding The aeration -settling treatment process will gradually produce excess solids, the natural result or by-product of the treatment. These solids will be periodically wasted out of the treatment system and stored in an aerated sludge holding tank where digestion and treatment continues until the solids are transported off site for ultimate disposal. B-11 Stand-by Power In the event of a power outage, it will be crucial to maintain a level of treatment. Stand-by power will be provided to operate one of the influent pumps to eliminate the potential for overflow of the station and one of the aeration blowers to maintain aerobic conditions in the aeration tank. A power outage will mean that water supply will be discontinued since wells will supply the project's water supply, thus flow to the plant will also gradually stop with depletion of the water system's water storage tanks. B-12 Plant Site The treatment plant site will contain several acres of the project to provide a buffer between .the plant and new or existing homes, In addition the plant will be completely fenced for security. To provide for possible future plant expansion and/or upgrade, excess land will be provided within the plant site. VII. OWNERSHIP, OPERATION AND MAINTENANCE A. OWNERSHIP OF UTILITIES It is intended that the water and sewer systems to be built to serve the project be conveyed entirely including land into the ownership of a private utility company. The utility company must be duly licensed and regulated by the NC Utilities Commission. The company must demonstrate the financial and physical ability to properly respond to the eventual homebuyers and regulatory agencies. B. OPERATION AND MAINTENANCE The private utility company must be able to demonstrate past success.in the operation of similar facilities and must maintain a staff of licensed operators holding valid certificates commensurate with the complexity of facilities to be operated. The utility must be able to respond within a regulatory required time period to any emergency. The utility will also be responsible for continuing maintenance of the plant. A stock of normally required spare parts will be supplied during construction and should be replenished as necessary by the utility. C. ENFORCEMENT OF WATER QUALITY STANDARDS The NPDES permit will provide for monitoring of the performance of the waste treatment plant by the utility company. Monthly reports of plant flow and performance must be submitted. In addition, periodic non -announced site inspections and sampling will be performed by representatives of the Regional Office of NCDEM. In the event the utility company fails to comply with any of the provisions of the plant permit, NC and Federal law provide for enforcement action and possible fines of up to $10,000.00 per day per violation. D. NPDES PERMIT RENEWAL The NPDES permit will be issued for a period of five years. NCDEM reserved the right to modify, change, or make more stringent the permit requirements at the time of permit renewal based on changes in site conditions, stream conditions and performance of the plant and utility. VIII. SUMMARY Crescent Land & Timber Corporation proposes to develop a new site in Iredell County. The project to contain approximately 825 acres will be served by central water and sewer facilities. Water facilities are proposed on the basis of a central well supply, storage, and water distribution. Wastewater facilities proposed include a sewage collection system and a waste treatment plant with discharge of treated effluent to Lake Norman. An NPDES permit has been applied for the discharge and the proposed plant will be so designed and constructed to consistently achieve the degree of treatment required by the permit. The plant will be owned and operated by a private utility company to assure responsiveness to homeowners and regulatory agencies, and preserve the present environmental quality of the area.
