Westall@ncmail.net> Organization: NC DENR - Asheville Regional Office To: Dave Goodrich <Dave.Goodrich@ncmail.net> CC: Kevin Barnett <Kevin.Barnett@ncmail.net>, Jackie Nowell <Jackie.Nowell@ncmail.net> Dave, In follow-up to our phone discussion today, this e-mail note will constitute the ARO's revision to the staff report I signed and sent to the NPDES Unit this week for this application. I have discussed this with Kevin and he supports this approach. The ARO recommendation to apply "reuse" wastewater limits to this facility was based on the commitment of the applicant (or his representative consultant) to provide treatment capability necessary to achieve this level of performance or effluent quality. We understand that to actually apply those limits as the NPDES "effluent limits" we would need a stronger direct relationship between this performance and water quality impacts (since the applicant doesn't to our knowledge plan to actually "reuse" this water on the project--i.e. this is not a reuse/NPDES discharge system). We do, however, see benefits to using the NPDES permit to "hold" the commitment of the applicant to provide this level of treatment/operation. Therefore, the ARO recommends that the following condition or one that accomplishes the same objective be included in the final draft permit (placed in the most appropriate area of the permit and referenced in the permit cover letter and permit cover page): "The permittee shall design, construct and operate the wastewater treatment plant for this facility in accordance with the State's requirements for treatment of wastewater for "use of reclaimed water" as described in NCAC 15A: 02H .0219 (k), with the following exceptions: 1. Compliance with the limitations described in 02H .0219 (k)(1)(iii)(I-IV) shall not be required by this permit, but that the facility must meet the permit limitations as described on the limits page of this NPDES Permit. 2. Continuous on-line monitoring and recording for turbidity or particle count as described in 02H .0219 (k)(1)(iv) shall not be required by this permit. 3. The design, construction and operation of a "five-day side -stream detention pond" as described in 02H .0219 (k)(1)(v) shall not be required by this permit. The objective of this condition in this NPDES permit is to require that all treatment components for this plant be appropriately designed, sized, built, and operated so that effluent quality would consistently approach the levels described in 02H .0219 (k)(1)(iii)(I-IV). Compliance with this condition will be evaluated by examining the specific details of the design components of the plant, the facilities actually installed the operation of the plant once it begins to treat wastewater and the effluent quality performance of the plant." This condition will need to be evaluated through the ATC process and in our (RO) examination of the actual plant, its 1 of 2 9/19/03 11:46 AM NPDES Application NC 0087700--Wade Hampton Horizons Estate operation and DMR data review. It is our intention to make specific reference to this condition as we review the plans for construction, do compliance inspections of the facility and examine the DMR data.

Average Flow cfs : 0.23 IWC % : 0.8 Primary SIC Code:_ SUMMARY OF FACILITY AND WASTELOAD ALLOCATION Robert Hampton is requesting the issuance of a NPDES permit for a 82,160 GPD wastewater treatment plant. The plant will treat domestic wastewater from a proposed resort and spa development, Wade Hampton Horizon Estates, which will include Club House, inns, restaurant, single family homes, suites, condominiums, villas and other related units. The Horizon Estates will discharge into UT Trout Creek in the Little Tennessee River Basin. The UT Trout Creek is not listed on the 2003 303d list for impaired streams in North Carolina. The stream is also not rated via monitoring or evaluation, however overall water quality in the subbasin is excellent. There is much history with this permit application. Attached notes will detail the background. After evaluation of most recently submitted alternatives, the most economically feasible option was direct discharge to UT Trout Creek. Alternatives indicated that there were not enough suitable soils for a viable nondischarge option. Performed Level B model of UT Trout Creek, must have summer limits of 5/ 1.5/6 to protect DO standard. Winter limits cannot be less stringent than twice the summer oxygen consuming limits per NCAC 2B .0404( c) therefore winter limits of 10/3.5/5 are recommended. NH3 limits for protection against toxicity. Fecal and TRC limits also required. Stream has very steep slopes. Model segment length was 0.36 miles and stopped at the beginning of a small pond. Tertiary treatment limits will be required year-round for protection of the dissolved oxygen standard of 6 mg/1 for trout class streams and protection against ammonia and chlorine toxicity. Semi-annually monitoring of TP and TN is also required. Nearest existing discharger is Singing Waters Camping Resort, located approximately 2-3 miles downstream on Trout Creek. There should be no interaction between the two dischargers. Draft permit must be reviewed by DEH since discharge is to WSIII Trout waters.

The project will be completed in phases, with the initial phase of construction requiring 6960 GPD, second phase 52500 gpd and third phase 82500 gpd. Requested is 82,160 GPD into UT Trout Creek Information provided by engineer indicated that DA = 0.226 mil And estimated 7Q10 flow is 0.039 cfs *This flow would be considered zero flow stream and DWQ procedure would not allow a wastewater discharge into this point. On January 17, 2003 called Gary MacConnell and told him that another site would need to be selected and even then Level B modeling would have to determine whether the stream could accept that much flow. He asked me to hold the project for a copy of days while he looked into the site and 7Q10 of the stream. 2/22/03 — Flow estimates - received fax memo from Daniel Vallero regarding new runoff calculations. They found that the 0.105 cfs supplied in the text of the report was correct. The info in Appendix E where the flow was 0.039 cfs is incorrect. Submitted a replacement page with the flow of 0.105 cfs. My evaluation of the discharge site had a smaller drainage area and a lower estimated 7Q10 flow. Wade Hampton estimates: DA = 0.226 mil , estimated 7Q10 flow is 0.105 cfs DWQ estimates: DA = 0.13 mil , estimated 7Q10 flow is 0.07 cfs * It should be noted that the flow estimate program indicates that the drainage area I determined was unuseable in this hydrologic area. The "Low flow Characteristic of Streams in NC" report indicates that in this hydrologic area, HA10, the drainage area in square miles below which indicated low -flow statistic generally has a zero value is probably less than 0.5 square miles. Both the engineer and I estimated a DA below 0.5 mi2. Will recommend that facility contact USGS and get flow estimate from them since there is a discrepancy between our two estimates and program indicates that the DA is unusable. EAA Review- TB, SAW, NS - 2/14/03 Should this be a phased permit -can it grow to this big of an area? Ask about the time frames for the building phases. Ask how they will design the plant @ 90,000 GPD Want data from USGS to verify the 7Q10 and 30Q2. Need letter from municipality of Cashiers saying that they would not accept their wastewater. What is the distance to pump to the nearest collection system or line for Cashiers? Check with Kevin Barnett of ARO. How much acreage is need for land disposal? Reevaluate surface drip. Will occupancy be seasonal or year round? 3/6/03 — Kevin Barnett of ARO Called to ask about possible connection to Town of Cashiers. Kevin said that the collection system is very short. Cashiers is on a self imposed moratorium. They are not at 80-90%. But the plant is bumping to 100% capacity every summer, but is only at 20% capacity in the winter. Would not be able to accept additional flow from this project. It is a seasonal town with a lot of second homes. The Wade Hampton project will have problems in the winter. A low rate drip in the woods is not out of the question for this project. He understands it will be developed with a lot of land. General public scrutiny will be the problem for building the project. The local people will want to know about the project. However, if you build it, they will come. Resorts will be busy in the summer. This project may be trying to compete with High Hampton, a sport and fishing resort. Wade Hampton has an existing country club w/ golf course further south of this project. Too far away to use in reuse alternative. 3/11/2003 — returned application and EAA packages to Wade Hampton Estates. Letter contained several questions requesting additional information on the project. Cc'd Gary McConnell, project engineer 4/9/03 — received letter from Mr. McConnell responding to the questions in the return letter. Called Mr. McConnell and indicated that a new application and new copies of the EAA needed to be sent in before we could proceed with the project. If changes had been made as far as phases, etc. that new copies of the EAA were required. He said that 2 everything was still the same, the phases have been combined. Told him that we only had one marked up copy of EAA and new copies would be needed. Mr. McConnell expressed his displeasure with the length of time that the project had taken. Asked why he had not received copies of the old application. Told him that the entire package had been returned to Mr. Hampton, the owner of the project. Mr. McConnell said that he would have copies of the application and EAA in my office tomorrow. He also complained that money and jobs was being lost while the project was not approved. That the length of time had been too long and he had been told that the project would be finished in October. Also said that he had stopped by my office and I was not here and should have been there doing my job. Requested to speak to my supervisor and complain about the length of time with the project. Continued to tell him that an application would still be needed to move on with the permit request, whether he spoke to my supervisor or not. Mr. McConnell indicated that something needed to be done and lawyers may have to be involved. Second Group EAA Review 1. Hampton Estates should be permitted only for 82,160-82,200 GPD although designed for 90,000 GPD 2. The option of connection to the Cashiers wwtp needs to be correctly addressed. Even though it is a private entity, McConnell and Associates could have approached the Tuckaseegee Water and Sewer Authority - Cashiers WWTP about the available option of a proposed discharger connection. The correct wasteflow of the Cashiers WWTP is 0.100 MGD and is noted in the chart of Jackson County dischargers in Appendix D of the EAA. It is incorrectly printed in the text on page 41n the Appendix chart should match the text. 3. Will ask Kevin Barnett of ARO to see if adjacent lands are available for purchase since there is not enough available land within the Hampton Estates. for land disposal. He may ask owner/applicant if adjacent land can be acquired. 4. The less dense development option of a 40,000 GPD development. Consultant needs to do a further explanation of the lost opportunity cost. The cost of the 40,000 GPD subsurface, reduced flow option is within 5% of the stream discharge option. April 30, 2003 Meeting with Robert Hampton, Gary McConnell Discussed the alternatives analyses that was provided and additional information needed. DWQ asked for more info on large diameter pipe nondischarge option, whether low pressure pipe option was evaluated, and that the price of subsurface disposal at 40,000 GPD was within 15 % of direct discharge options and could be chosen as the treatment. Mr. Hampton indicated that he initially wanted to use septic systems but that it wouldn't work, if he wanted to maintain the natural scenery. Mr. Hampton has indicated that he had started construction and roadwork already. Will take 3 months to put the sewer in. Builders ready to start on the villas. Phase 1 and II have been combined now into the new Phase 1. Phase II is now on schedule to start. They buying additional property for third Phase, which would be another project. He wants to start by March 2004. He says there are underground springs and septic systems would pollute them. Effluent discharged will be reuse quality. McConnell indicates that property doesn't lend itself to drip irrigation. If a storage pond is required it would be -tough to operate. Dave G. indicated that a conjunctive use permit would be more conducive to DWQ. A drip system when it could be operated and the other time discharge to stream. McConnell says that orchards and vineyards would lend themselves to seasonal irrigation of water. Some holding tanks could be done. It would be difficult. Ground ready for underground utility, etc. Road beds already cut. Additional Information needed from Hampton and McConnell 1. Needs to demonstrate lost opportunity costs if project at lower flow of 40,000 GPD is built. 2. Need to get local government signoff-notarized -- Letter from Jackson Co. indicating that there were no zoning ordinances in place. Regs indicate that letter must be notarized. 3. Need to submit loading rate calculations — they are referenced but not actually shown 4. Need to present references for cost estimates June 24, 2003 - additional information received Showed that direct discharge is the most economically feasible choice. Lost opportunity cost of $3.2 M dollars if site is reduced by 100 residential units (C $32K per unit) to a 40,000 GPD treatment plant. Provided loading rate calculations from certified soil scientist Provided references for costs of equipment Did not provide notarized local government signoff Performed Level B model of UT Trout Creek, must have summer limits of 511.516 to protect DO standard. Fecal and TRC limits also. Stream has very steep slopes. Model run stopped at the beginning of a small pond. Winter limits cannot be less stringent than twice the summer oxygen consuming limits per NCAC 211 .0404( c). Winter limits of 10/3.5/5. NH3 limits for protection against toxicity. Kevin Barnett of ARO- will go to the site upon receipt of the application. He thinks that a downstream discharge, Singing Waters Camping Resort, will have something to say about the new discharger.

Many of the issues discussed at our last meeting have been addressed in these revised pages. Other information is being furnished at your request to better document our assumptions. Outstanding items are discussed below. There was some discussion regarding "lost acreage". Land has not been lost. However, due to: built upon land, set backs, (there will be numerous wells on site), and unsuitable land, the available acreage identified in the soils report has become significantly less. 2. Large diameter pipe has been discussed in more detail within the analysis. It is included in the on site wastewater regulations (15 NCAC 18A.1956). 3. Low Pressure Pipe was not considered a viable alternative due to the steep slopes, springs, and varying topography. This option is discussed in the analysis. 4. The subsurface disposal option with a reduced flow of 40,000 GPD has been reevaluated to include opportunity costs. 5. Local Government Sign off is included in Appendix F 6. See attached letter from S&ME with proposed loading rates. 7. Please see referenced packaged wastewater package plant quote for referenced cost. We trust these responses, along with all supporting information and documentation will answer your questions. Please contact me or Julia Keith, E.I. with any questions or comments at (919) 467-1239.

Project Background The Wade Hampton Horizons Estate is a proposed 119.9 acre multi -use development consisting of: a club house, three inns, restaurant, a spa resort with condominiums and suites (The Lodge), single family residences, mansions, cottages, villas, and other miscellaneous amenities. The development will be located in Jackson County about five miles north of Cashiers, North Carolina. The development has a northwest aspect with distant views of the Great Smoky Mountains National Park. The site offers unique and varying vegetation types, numerous springs, two streams, ponds, and an adjacent waterfall. Because of the environmentally sensitive developer, the Wade Hampton Horizons Estate others a one of a kind development which enhances the beauty of the mountains of North Carolina. The only municipality within the vicinity of the development is the Town of Cashiers which is approximately five miles away, with driving distance being about 10 miles. Potable water will be provided to the development by springs located throughout the site. The slope of the land where the development is to be located averages about 21 percent and is mostly heavily forested. However, some areas are significantly flatter or steeper. For further information concerning the site and topography, please refer to the soils report located in Appendix A and two site plans located in Appendix B. The purpose of this Engineering Alternatives Analysis (EAA) is to outline the various wastewater treatment and disposal alternatives for the proposed development and determine the most feasible 1110� alternative. Based on this analysis and the associated costs for the various alternatives, the owners of the proposed development are requesting authorization to discharge up to 82,160 GPD into an unnamed tributary of Trout Creek which is part of the Little Tennessee River Basin under a NPDES permit issued by the Division of Water Quality (DWQ). According to Division records, this stream is located in Subbasin 40402 of the Little Tennessee River Basin and is classified as "WS-III Tr" waters. The "Tr" classification refers to the fact that these waters have conditions which shall sustain and allow for trout propagation and survival of stock trout on a year-round basis. 3. Wastewater Analysis of Proposed Development Projected wastewater flows have been developed for the proposed Wade Hampton Horizons Estate. Flows for the development are based on three phases of development for the 119.9 acre multi -use development which consists of a club house, three inns, restaurant, a spa resort with condominiums and suites (The Lodge), single family residences, mansions, cottages, villas, and other miscellaneous amenities. Wastewater from the development is considered to be completely domestic, with no industries within the property. Based on textbook values, the raw wastewater is expected to have an average BQD5 concentration of 200 mg/l and a total suspended concentration of 200 mg/l. The average wastewater quantity or flow rate at build out will be the basis for design. It is based on the design flow rates outlined in 15A NCAC 2H .0200. A value of 120 gallons of wastewater per day, per bedroom is used for dwelling units. Bedrooms in the r"b� spa are allocated 200 gallons per day per bedroom for resorts and each seat in the restaurant is Engineering Alternatives Analysis Wade Hampton Horizons Estate Page 2 The Hampton Club, Inc. 4k r""'1 allocated 40 gallons per day per seat. The development will generate approximately 82,160 gallons per day (GPD) (basis for permit) of raw wastewater at build out, based on projections presented in Table 3-1. The actual wastewater treatment plant will be designed based on an average daily flow of 90,000 GPD, to be conservative.

Evaluation of Disposal Alternatives Based on the 82,.100 GPD of wastewater which will be generated by the proposed development, the following wastewater treatment and disposal alternatives have been evaluated to determine their economic and environmental feasibility: • Connection to an existing wastewater treatment system including Publicly Owned Treatment Works (POTW) and Privately Owned Treatment Works. Engineering Alternatives Analysis Wade Hampton Horizons Estate Page 3 The Hampton Club, Inc. • Surface and subsurface land based alternatives including individual non -discharge systems, community subsurface systems (both standard and innovative systems), drip irrigation systems, and spray irrigation systems. • Wastewater Reuse • Surface Water Discharge • Combinations of various disposal alternatives Each alternative is discussed in detail including proposed treatment processes, wastewater disposal options, and Present -Value -of Costs Analysis where feasible. All capital, installation, construction, opportunity, monitoring, and operation and maintenance costs associated with the various alternatives outlined below can be found in Appendix C. A. Connection to a Sewer -Collection System The North Carolina Department of Environment and Natural Resources: Division of Water Quality has issued nineteen (19) active NPDES permits in Jackson County, as summarized in Appendix D. Of these discharges, only the Singing Waters Camping Resort discharges into Trout Creek. This is a small facility as summarized below: Permit Facility Receiving Stream Flow f4m'1 NC0038687 Singing Waters Camping Resort Trout Creek 71)500 GPD Although it is the closest facility at about four (4) miles away, it is not considered a viable alternative to connect to due to its size, distance, and seasonal nature of its operation. The closest wastewater treatment plant of significant size is the Cashiers Wastewater Treatment Plant, as summarized below: Permit Facifily Receiving Stream Flow NC0063321 Cashiers WWTP East Fork Chatooga River 100,000 GPD This facility which is owned and operated by the Tuckaseigee Water and Sewer Authority is more than ten (10) miles away by road and located in another sub -basin. Therefore, it is not considered a viable alternative to connect to based on cost and environmental concerns. This alternative was not evaluated any further due to the cost of constructing a force main that distance and the degree of difficulty in constructing a force main in this area due to shallow bedrock and extreme topography. In addition, because the owner is a private developer, the force main could not be constructed in the. Department of Transportation's public right-of-way. Therefore, easements would be required from every property owner for the entire ten plus miles route. The seventeen remaining wastewater treatment systems in Jackson County are either small (no larger than 150,000 gallons per day), and/or significantly farther than the Cashiers Wastewater Treatment Plant. Therefore, none of these facilities offers a viable alternative to furnish Engineering Alternatives Analysis Wade Hampton Horizons Estate Page 4 The Hampton Club, Inc. C'i wastewater treatment for the Wade Hampton Horizons Estate, and they are not given further consideration. B. Land Based Disposal The total acreage of the proposed Wade Hampton Horizons Estate development is approximately 119.90 acres. The original property or Site 1 occupies approximately 31.70 acres while Site 2 or the newest addition occupies approximately 88.20 acres of land. Of the total acreage, the owners have set aside approximately 35 acres for green space which are located in common areas, areas adjacent to creeks, and in the estate or mansion lots. These natural areas will be defined in the property deeds and are to promote the unique flora and fauna of the area. Therefore, approximately 85.90 acres remain for the proposed development and wastewater treatment and disposal. S&ME, Inc. completed a preliminary soil evaluation of the proposed site in order to identify usable areas for wastewater disposal and establish applicable loading rates. Their complete evaluation is located in Appendix A. Based on their evaluation, approximately 13.17 acres of Site 1 and 24.85 acres of Site 2 for a total area of 38.02 acres are usable, throughout the total site. This represents about 41.51 percent of Site 1, 28.17 percent of Site 2, or 31.71 percent of the total area being potentially usable for an on -site system The remaining areas have greater than 65 percent slope, shallow soils, and/or they are within the various buffers. from property lines, streams or other water features as required by the Division of Water Quality or the Division of Environmental Health. This makes these areas unsuitable for wastewater disposal. It is estimated that approximately 20% of the entire property will be built upon with buildings and infrastructure. Based on the proposed site plan as contained in Appendix B, approximately 5.0 acres of Site 1 and 7.5 acres of Site 2, or 12.5 acres of the entire site are available for wastewater disposal at build -out of the project, when building footprints, setbacks and natural areas are subtracted for available area. Because of the topography, vegetation, irregular shapes of available areas, footpaths, setbacks from proposed wells, and other small miscellaneous appurtenances such as distribution lines and power lines approximately 50 percent of the remaining area is actually unusable. This leaves approximately 2.5 acres of Site 1 and 3.75 acres of Site 2, or 6.25 total acres available for wastewater treatment and disposal. The land based disposal alternatives have been evaluated as follows: Low Pressure Pipe (LPP): The average slope of the property is about 21 percent which eliminates the low pressure pipe alternative. LPP systems can be used on steeper slope when the slopes are relatively uniform. However, the varied topography, steep slopes and broken up areas make this option impractical: • This option is not considered further Spray, Irrigation: The average slope of the property is about 21 percent which eliminates spray irrigation as a viable alternative. Typically, it is recommended to avoid spray irrigation of effluent on slopes greater than 8 to 10 percent due to the potential of runoff It may be possible to irrigate Engineering Alternatives Analysis Wade Hampton Horizons Estate Page 5 The Hampton Club, Inc. isolated areas such as the vineyard or orchard. However, theses areas are small and the amount of water irrigated would be insignificant and the irrigation of these areas would be seasonal. Large Diameter Pipe: Large diameter pipe systems are often used in the mountains where steeper slopes are present. In these types of systems, 8 or 10-inch diameter corrugated pipe is used in lieu of the 4 or 6-inch pipe, for drainage. When.8-inch pipe is used, an actual trench bottom width of 15-inches is used, but 24 inches is used for design purposes with a separation between the design trench bottoms of 6 feet. When 10-inch pipe is used, an actual trench bottom width of 18-inches is used, but 30 inches are used for design purposes with a separation between the design trench bottoms of 6 feet. Based on a long term acceptance rate (LTAR) of 0.5 to 0.7 gallons per day per square foot (gpd/ft2), this equates to an effective loading of total area of 0.125 to 0.175 gpd/ft2. Based on a LTAR of 0.5 to 0.7 gpd/ft2 or an effective loading of 0.125 to 0.175 gpd/ft2 for total area, approximately 30.18 to 21.56 acres of land, including repair area, will be required for this type of subsurface aisposa option. Based on the design of this type of system even more area would be required to accommodate setbacks, placement of pipe, and septic tanks. Because this option requires more land than what is available, this option was not evaluated any further. Subsurface Drip: When designing a subsurface drip irrigation system, one half of the published LTAR is typically used as the design value, assuming that 2-foot spacing of lines provides for total coverage of the area. Based on a published LTAR of 0.5 to 0.7 gpd/ft2 for conventional trench bottom, this yields an effective loading of 0.25 to 0.35 gpd/ft2 for the total area. Approximately 15.09 to 10.78 acres of land, including repair area, will be necessary to dispose of the wastewater generated by this project through a subsurface drip irrigation system. Cost analysis of this type of system is outlined in Appendix C. Disinfection is not typically required for subsurface disposal systems. However, due to the large volume of wastewater to be treated and the sensitivity to the freshwater springs in the area, a wastewater treatment facility with aeration and clarification is proposed in lieu of septic tanks, pump tanks, and effluent filters. Due to the potential of shallow bedrock and the freshwater springs throughout the site, installing septic tanks and pump tanks at each facility would also not be viable or cost effective. Please note that this alternative was evaluated but due to the amount of land required to construct the subsurface drip irrigation fields, this alternative in actuality is not viable. This alternative would stretch the technology limits to the maximum based on distribution and monitoring of wastewater disposal. Surface Drip: Based on a surface loading of 0.80 to 1.12 inches per week, approximately 26.50 to 18.93 acres of irrigation land is required for a surface drip irrigation to dispose of the wastewater generated by Wade Hampton Horizons Estate. The cost analysis for this system is addressed in Appendix C. This type of disposal system will require a wastewater treatment facility with aeration, clarification and disinfection capable of meeting secondary limits. In addition, inclement storage will be required. Due to the climate in this area, it is estimated that 120 days of storage, or 5.4 million gallons, will be required. Please note that this alternative was also evaluated but due to the amount of land required to construct the surface drip irrigation fields, this alternative is actuality not a very viable option. This alternative would also stretch the technology limits to the maximum based on distribution and monitoring of wastewater disposal. Engineering Alternatives Analysis Wade Hampton Horizons Estate Page 6 The Hampton Club, Inc. k� C. Wastewater Reuse The developer of Wade Hampton Horizons Estate intends to minimize disturbance as much as possible. Landscaping will be constructed and maintained around the dwelling units and along walkways. Landscaping will highlight species which are native to the area. In addition there are plans for a small boutique orchard and a boutique vineyard. Because of the limited amount of planned landscaping, the potential for reuse through an irrigation system is minimal and limited to small isolated areas. In addition, due to the extremely cold weather in this area during the winter, irrigation would not be possible during the months of October through March. At this time there does not appear to be any significant non -potable water use options (estimated to be less than 51000 GPD) in the development, therefore, this alternative was not evaluated any further. Once the facility is operating and the wastewater being generated by the WWTP meets the reclaimed water standards, the owner may reevaluate the potential for wastewater reuse around the development. D. Surface Water Discharge The US Geological Survey (Curtis Weaver) was contacted to obtain stream flow information. Their records did not include any flow estimates specific to the propose location. However, Mr. Weaver did calculate the 7Q 10 flow for the drainage area (see Appendix E). He provided an email response and written report. The 7Q 10 is the average flow rate for a seven day period following a 10-year storm event. The drainage area for the unnamed tributary of Trout Creek /0=*) where the proposed discharge will be located is approximately 0.22 square miles. The 7Q 10 for the area was found to be 0.13 cubic feet per second (cfs). This stream flow exceeds the threshold of 0.05 cfs for a positive flow stream. The USGS low flow report by Mr. Weaver and correspondence with Mr. Weaver may be found in Appendix E. The proposed discharge point is also shown on the USGS quad sheet for this option with the approximate property boundaries, in Appendix E. /0. Appendix C contains a cost estimate for both a wastewater treatment facility with a tertiary filter and one without a tertiary filter. Associated laboratory and monitoring costs were also developed to reflect the various sampling regimes which may be required by the Division of Water Quality. The Present -Value -of -Costs Analysis for this alternative is also included in Appendix C. The proposed wastewater treatment facility will be a dual train extended aeration wastewater treatment facility and will include flow equalization (sized for a minimum of 25% of the facilities hydraulic capacity). The facility will provide 24 hours of detention in the aeration chamber and at least 4 hours of detention in the clarifiers. Disinfection will be achieved by sodium hypochlorite with dechlorinatioh, or through multiple banks of ultraviolet units. The wastewater treatment facility, discharge piping, and receiving stream are all located within boundaries of the proposed development. Engineering Alternatives Analysis Wade Hampton Horizons Estate Page 7 The Hampton Club, Inc. E. Disposal Combinations In order to eliminate the inclement weather storage pond, it is possible to combine the surface drip irrigation alternative with the discharge alternative. This combined alternative would further increase the overall total cost required to install both systems making this alternative even less viable. Another combination mentioned earlier in the report would be to combine any of the proposed disposal options and reusing a portion of the effluent for on -site irrigation. However, there does not appear to be enough demand for the reuse water in this development to justify its use. Reuse in isolated areas could be used but this should not be considered the major means of effluent disposal. There are no other viable disposal combination alternatives available. F. Less Dense Development What are the consequences of reducing development on the property to both reduce flow and to increase the area for disposal. If the total flow is reduced to about 40,000 GPD it is possible that the site could assimilate the treated wastewater with either surface, subsurface, or large diameter pipe technologies. The large diameter pipe with septic tanks option is not considered due to the numerous springs on site. Surface drip with a treatment plant requires a large storage pond which is costly. Therefore, the cost of treating 40,000 GPD with a wastewater treatment plant and subsurface drip irrigation is considered. These costs are presented, however, the reduced housing on site makes the project cost prohibitive based on land and infrastructure costs. The reduced housing is presented as an opportunity cost for not developing the land to its potential. 5. Recommended Disposal Alternative Based on review of the available alternatives for the proposed development and the economic and environmental impacts, the recommended option is the Extended Aeration Wastewater Treatment Facility with Direct Discharge. Not only is this alternative the most economical feasible option, but also the most reliable system. Typically, drip irrigation systems greater than 50,000 GPD become difficult to manage due to the number of valves, controls, and zones associated with systems that large. In addition, due to the presence of shallow and fractured bedrock, a surface or subsurface drip irrigation system could result in negative impacts to the groundwater/aquifer in this area, as well as to the valued pristine springs on the property and surrounding areas. Due to the yearly stream flow and existing topography, the environmental impacts are expected to be non existent or minimal. The topography offers constant aeration of the stream throughout the year. Engineering Alternatives Analysis Wade Hampton Horizons Estate Page 8 Explanation and Justification of Equipment, Quantities, and Unit Cost: Equipment, Construction, Installation, and Operation and Maintenance costs were estimated based on similar projects or discussions with manufacturers, contractors, and/or sales representatives General 1. An interest rate of 6.875% and a time period of 20 years was utilized in calculating the net present value of the estimated operation and maintenance costs. Wastewater Treatment Alternatives 1. Wastewater Treatment to Secondary Levels averages about $5.00 per gallon per discussions with prefabricated steel wastewater treatment plant manufacturers and sales representatives. These costs were also- compared to similar wastewater treatment facilities which were recently bid. 2. Due to shallow bedrock, fresh water springs, and extreme topography located throughout the project site, a central wastewater treatment facility is proposed in lieu of multiple septic tanks, pump tanks, and effluent filters in the Subsurface Disposal alternative. With wastewater flows of this volume and the proposed density of the development, it is also more viable and cost effective to- construct one centralized wastewater treatment facility #han having septic tanks and pump tanks at each facility. 3. The standby generator and electrical construction costs will be greater for the Subsurface and Surface Disposal alternatives (through drip irrigation) due to the additional pumps, controls and valves required to operate the irrigation fields. The area required for the fields will require a large number of multiple zones in order to maintain the required pressures throughout the system. 4. Due to the volume of wastewater generated by the proposed development and the complexity of the wastewater treatment system, a Grade III biological wastewater operator will be required for each of the proposed alternatives. 5. Disinfection is typically not required for subsurface disposal systems, although in areas of shallow soils the Health Department may require disinfection. The proposed costs associated with the Subsurface Disposal alternative assume- disinfection will not be required. 6. The Surface Drip Irrigation alternative will require the construction of an inclement weather storage pond. Due to the cold weather in this part of the State it is assumed that approximately 120 days of storage, will be required. This equates to a minimum 10.8 million gallon storage pond. This pond will also require two feet of freeboard. Construction of a pond this size will be difficult in this area due to shallow bedrock and springs. In addition, the shallow bedrock will also require that the pond be lined to ensure protection of the groundwater in this area. Construction of the pond will require the excavation and compaction of approximately 65,000 cubic yards of material at a cost of $1.00 to $2.50 per cubic yard for removal and compaction. A synthetic liner will cost approximately $0.75 per square foot for installation. These costs assume that all soil material required to construct the dikes can -be obtained •on -site. If soil material is required- to be hauled -to the project site for the construction of the storage pond dikes and or if significant blasting is required, the capital costs will increase. 7. Opportunity cost is considered for the reduced flow option of 40,000 gallons per day. This cost represents the lost income of constructing a less dense development. Based on the proposed development this would represent the loss of approximately 100 residential units. These units would be /0"� spread out over the various types of properties. However, the projected profit from an average unit is �..� about $32,000, as this is a high end development. Wastewater Disposal Alternatives 1. The Direct Discharge Alternative will require the construction of approximately 250 linear feet of 6-inch force main to transport the treated effluent from the wastewater treatment facility to the receiving stream. The force main will discharge onto to cascade aeration device. 2. Due to the large area required for drip irrigation, both the Subsurface and Surface Drip Irrigation alternatives include costs for multiple zones, controls, pumps, and disc filters. Six inch supply piping will be required to transport the effluent from the irrigation pond to the drip irrigation fields and also take the backwash from the fields back to the wastewater treatment facility. 3. Construction costs for the installation of the drip irrigation line is greater in the Subsurface Disposal alternative due to the fact that a 6 to 12 inch deep trench will be required. The cost also includes backfilling of the trench.

A brief assessment of the low flow characteristics known for that area resulted in a 7Q10 yield ranging from 0.5 to 0.6 cubic foot per second per square mile (dsm) as being appropriate for the streams of interest. When I provided this information to her, I also faxed excerpts from a statewide low flow report that was prepared in the late 1980's/early 1990's, "Low -flow characteristics of streams in North Carolina" (USGS Water -Supply Paper 2403 by Giese and Mason, 1993). My notes also indicate that she apparently called back to cancel the request for a formal assessment of the low -flow characteristics at these streams. Yesterday (April 3, 2003), 1 again examined the low flow information that we have and identified several nearby sites where low flow characteristics have been determined based on discharge records. Based on three nearby sites, the following low flow yields (in units of cfsm) were determined for your site of interest: 7Q 10 = 0.57 cfsm 30Q2 =1.03 cfsm 'Winter" 7Q10 = 0.65 cfsm 7Q2 = 0.86 cfsm A quick delineation of the drainage area using your site identified on the fax location map resulted in a determination of 0.22 sgmi for the drainagea area. Thus, application of the above yields using the drainage area would result in the following low flow characteristics estimated for your site: 7Q10=0.13cfs 30Q2 = 0.23 cfs "winter" 7Q10 = 0.14 cfs 7Q2 = 0.19 cfs 04/04/2003 Page 2 of 2 The average annual discharge for streams in this area is about 3.5 cfsm, meaning that an estimated average discharge is about 0.8 cfs. I have attached a bitmap (.bmp) image showing the site location and drainage -area delineation. If you wish for the USGS to proceed with the formal evaluation. please let me know. Based on yesterday's assessment, the above yields would likely be those provided in the formal evaluation. If you have questions about this information, you can contact me at (919) 571-4043.

Vallem, Project Engineer MacConnell & Associate4, P.C. P.O. Box 129 1 Morrisville, North Carolloa 27560 Year Mr. Vallero: In response to your request for low -flow data, the U.S. Geological Sarvoy (USUS) does not have site-spe. cific, low -flow discharge Oata for Unnamed tributary to Trout Creek at Big Ridge, NC (station id 0350750625, drainage area 0.22 jW2). The low -flow characteristics that are provided on the attached sheet have been computed by correlating the runoff ehareoteristics of nearby partial -record sites in vicinity of the request site. Please note That the flow estimates do not account for the presence of any diversions or regu- lation, present or future, V(hich may occur upstream of the request site. Low -flow characteristics previously determined for three nearby USGS partial -record sites — with drain- age areas ranging from 3.f6 to 7.69 mil — were used to estimate the low -flow discharges for the request site. An average of the lov+r-flow yields (expressed as flow per square mile drainage area) was applied using the drainage area determined for the request site. The average 7Q10 low -flow yield determined from the three index sites was 0.57'cubic foot per second per square mile p3ls)/trti2]. Similarly, for the 30Q2, the tow -flow yield was determined to be 1.03 (ftl/s)/m12. The magnitudes in the abgv, low -flow yields are characteristic of strearnflows in the southwest mountains area of North Carolina. H�sterieal records of discharge collected at sites in this area are among the highest (in terms of yields) for strums in the State. The average annual discharge for streams in the vicinity of the nearby Highlands/Cashiers area ranges frorn 3.0 to 4.0.(fts/s)lmi2, compared to values in the range of 0.9 to 1.$ for much of the Stale. A charge for accessing and processing information has been assessed to partially offset these costs. Your requested data and an invoice covering processing costs for these data are enclosed. Please forward the original bill with your ehk to the U.S. Geological Survey.12201 Sunrise Valley Drive, MS 271, Reston, Virginia 20192. These data are prellmina* and subject to revision pending approval for publication by the Director of the U.S. Geological Survey, a p d are made available through our cooperative program of water -resources inves- tigations with the North Ckolina Department of Envirotunent and Natural Resources.

Re: The Hampton Club, Inc. Wade Hampton Horizons Estate NPDES Permit and Engineering Alternatives Analysis Jackson County MacConnell & Associates, P.C. Project No.: B18701.00 Dear Ms. Nowell: 909 Aviation Parkway Suite 1400 Morrisville, NC 27560 Fax 919-319-6510 In your letter to Mr. Robert Hampton, Jr., Esq. dated March 11, 2003, you posed several questions and comments. Your questions and comments are presented below with our responses. We request that you do everything possible to expedite the review process. The review process has extended months beyond the date promised by individuals within your department. Significant amounts of capital have been invested in the project which will provide much needed jobs for area workers. Because of the delay, the original Phase I and Phase II will be combined into the new Phase I, and the original Phase III will then become the new Phase II 1. Please re -check the subtotal phase II and III flows in Table 3-1 on page 3. Response: Please note new Table 3-1 as presented in attached page 3. Please replace this page in the latest submittal. Due to delays in the review process, the original Phase I and Phase II have now been combined to the newlPhase I and will be 58,160 GPD. The changes have no effect on the final requested permitted flow of 82,160 GPD, nor do they affect the WWTP Design flow of 90,000 GPD. 2. What are the anticipated time lines for completion of each phase of the project? Response: Because of the delay caused by the review process, Phases I and II have been combined into the current Phase I which will be completed within one calendar year. Phase III, now being Phase II, will be complete within one calendar year after the completion of the expanded Phase I. 3. Please provide information on how the treatment plant for Wade Hampton Estates will be designed. The project lists the first phase as less than 7,000 GPD, followed by approximately 50,000 GPD, then up to 82,000 GPD. How will the treatment facility be designed so that as little as 7,000 GPD will be efficiently treated in a plant with a design capacity of 90,000 GPD? Response: Phases I and II have now been combined into Phase I. The Phase I total flow is now 58,160 GPD. The design of the treatment plant is capable of treating such flow. 4. Will the occupancy, of this resort be seasonal or year round?' Response: The occupancy of this resort will be year-round. / 5. Please contact USGS and request stream data for written verification of the drainage area, average flow, summer and winter 7Q10 flows and 30Q2 flow for the proposed discharge point into UT Trout Creek. This information is being requested because there is a discrepancy in the flow information provided and DWQ estimates of the drainage area and stream flows. The cost of flow estimations from USGS should be approximately $150. Response: Please find attached the information provided by the USGS. Their correspondence confirms what we have submitted to you since our original submittal. As we discussed, there was a typo in the original submittal, but this did not affect the actual drainage area nor calculated flows. 6. Your report indicates that the Cashiers WWTP approximately 5 miles away from the project, however connection to the Cashiers WWTP is not evaluated as an option. Please estimate the cost of the connection alternative or provide a letter from the Town indicating that they will not accept wastewater from this project. Response: Cashiers is not an incorporated town. Since no Town government exists, taking the suggested action presented in comment number six is impossible. The Cashiers WWTP is a private entity, which serves various entities around Cashiers. The Cashiers WWTP is about five horizontal miles away from the proposed development, by sight. The plant is an estimated to be about ten logistical miles away from the development when topography and pipe -routing are accounted for. The Cashiers WWTP does not even serve the Lake Glenville area which is much closer. Multiple pump stations and easements would also be required to deliver wastewater to the Cashiers WWTP. The option was eliminated from consideration during the drafting of the report when it became evident that this option is not practical nor economically justifiable, and because no Town of Cashiers exists. The Cashier WWTP is also a small facility with a permitted flow of only 7,500 GPD.I &na'Vwt 17&,M,&,t �w S /QU, uu a 6/0 7. The land based disposal section indicates that the 35 acres of the project has been set aside of common areas, mansion lots, etc. All the land disposal alternatives indicate that between 15.1 to 21.2 acres would be needed for the subsurface drip and surface drip irrigation alternatives "to dispose of the wastewater generated by this project." Please reevaluate these alternatives more clearly. Explain why additional land from the set aside common areas, etc. could not be used for either of these alternatives, or why the set aside areas cannot be in the provisionally suitable or unsuitable soils. Response: During the study phase of the project, areas were given careful consideration for subsurface disposal or surface irrigation. Based on the footprints and setbacks from existing creeks and streams, and proposed ponds some of the better soil became unusable. Some of the common areas and mansion lots are not practically usable because they are broken up into smaller areas for footpaths, walkways, drives and various structures. These small parcels of land are not desirable for laying out drip irrigation systems in which longer runs for drip line are desirable. We have designed approximately 30 drip irrigation systems of various sizes throughout the state. In our opinion, drip irrigation technology would be stretched to its limit, even if the land was available on most of this site. In addition to the over riding technical issues of drip irrigation on this site, it is not economically justifiable. 8. A less dense development plan for 40,000 GPD is discussed on Page 8 of the alternatives analysis. Please provide additional information showing phases and site plan maps, if available. Response: The developer evaluated the 40,000 GPD option and found it to be grossly cost -prohibitive. Because it was not economically justifiable, there was no need to develop costly site plans for a project which would not be built. An analysis of such an alternative would be a misuse of time and resources. Therefore, the proposed flow of 82,160 GPD is required for the economic viability of the project. 9. Please provide the specific references for the unit costs in the construction estimates. Response: All unit costs are based on recent bids and projects, as well as quotes from manufacturers and contractors. Operation and maintenance costs are based on contacts with contract operators and manufacturer experience with parts and service. Specific bid tabulations, manufacturer's information, and contract operator information considered in the cost estimates are available at the office of MacConnell & Associates, but are too voluminous to be included with this submittal. We trust these responses, along with all supporting information documentation from USGS will answer your questions. Please contact me or Daniel J. Vallero, E.I. with any questions or comments at (919) 467-1239. Thank you. Sincerely, Gary S. cConnell, P.E.

The Commission shall not approve a permit application for any facility which a city or county has determined to be inconsistent with its zoning or subdivision ordinance unless it determines that the approval of such application has statewide significance and is in the best interest of the State. An applicant for a permit shall request that each city and county government having jurisdiction issue the statement required by this subdivision by mailing by certified mail, return receipt requested, a written request for such statement and a copy of the draft permit application to the clerk of the city or county. If a local government fails to mail the statement required by this subdivision, as evidenced by a postmark, within 15 days after receiving and signing for the certified mail, the Commission may proceed to consider the permit application notwithstanding this subdivision. 1 'C Mr. Robert Hampton,Jr. The Hampton Club, Inc.

Klimek, P.E., Director Division of Water Quality September 5, 2002 Subject: NPDES Permit application NCO087700 Wade Hampton Horizons Estate Jackson County The Division received your permit application on August 13, 2002. The NPDES staff has since conducted a review of the package to verify that the deficiencies documented in the return letter (2165) previously sent to you have been addressed. Please note that the correct application fee for NPDES permits of this type is $715.00. Please submit the fee, payable by check to NC DENR, within ten days of your receipt of this letter. Failure to submit the proper fee typically results in the return of the permit application; however, as this deficiency was not mentioned in the previous review & application return, the Division will begin review of your application. Mrs. Jacquelyn Nowell of the NPDES Unit will review your application. Mrs. Nowell will contact your Authorized Representative (Gary MacConnell of MacConnell & Associates) if further information is needed about this project. Please note that the NPDES Unit has currently has 3 vacant positions; the Unit has not been fully staffed since the first quarter of 1998. Our remaining permit writers are currently carrying extremely heavy workloads. While we do not expect severe delays in handling your request, be aware that your application is one of many that Ms. Nowell is currently reviewing. If you have any additional questions concerning the subject application, please contact Mrs. Nowell at (919) 733-5083, extension 512. Sincerely, Charles H.

In accordance with Division policy, we must hereby return the attached permit application received on June 5, 2002. After a preliminary review by Mr. Michael Myers of the NPDES Unit, the Division has determined that the application package lacks the following items: Local Government Review. The Division requires local government signoff from any city or county having jurisdiction at the proposed site. Enclosed is a Local Government Review form. The application package should include one form signed and sealed by each city or county having jurisdiction at the site. • Complete evaluation of discharge alternatives. The Division requires applicants for new permits to fully document all alternatives to surface water discharge (15A NCAC 2H.0105 (c)(2)). The enclosed guidance document will assist you in preparation of the analysis. Deficiencies in the FAA include: ➢ There is no flow justification for the two flow calculations related to "The Lodge" in Phase II of the project. ➢ Reserve capacity cannot be used as part of the flow justification. The 90,000 gallons/day discharge rate cannot be justified based on the FAA. You may choose to re-subtnit your application with a lower flow rate. ➢ The EAA does not address alternative development scenarios to increase the useable acreage for a non -discharging system. If you wish to reapply for an NPDES permit, correct these items before resubmitting the EAA. Submit the items listed above and the items returned to you in one package. If you have any questions about the NPDES permit process, contact Mr. Myers at the address or telephone number fisted below. Questions about permitting restrictions uruque to your area should be directed to Kevin Barnett of the Asheville Regional Office at (828) 251-6208. Sincerely, Charles H.

Facility Location: Wade Hampton Estates PO Box 2807, 4317 Big Ridge Road Cashiers, North Carolina Project County: Jackson Wastewater Source: Domestic wastewater from a private developer project. Summary: The following alternatives were evaluated: • Connection to POTW and private sewer system • Septic tanks • Subsurface irrigation system • Surface drip system • Spray irrigation system • Wastewater reuse • Surface water discharge Applicant concluded that septic tanks, connection to POTW/private sewer, and spray irrigation are technically infeasible. Therefore, no cost analysis was conducted. Cost analysis were conducted on surface and subsurface drip systems and on surface water discharge. Applicant concluded that surface water discharge was the most environmentally sound alternative of the economically feasible alternatives. Comments: For the most part, this Engineering Alternatives Analysis was a well done and documented. However, following comments should be addressed prior to resubmittal of the application. OW N. C.

Reserve capacity cannot be used to justify flow. It is the opinion of the Division, that 90,000 gpd has not been justified. The applicant may reapply at a lower flow rate. The application does not contain Local Government Signoff. The applicant should evaluate different development scenarios to increase the usable acreage.
