The Event Center will consist of ten (10) 2 bedroom cabins and a 300 seat event center with kitchen. The site has been deemed unsuitable for ground absorption sewage treatment systems by Ferguson Walker L.S.S.. The proposed system is to be sized for 6,000 gallons per day and has been designed to convey all wastewater from the proposed facilities, including greywater, to the new Discharge System. This application is being submitted with the intent to gain an Individual Discharge Permit. The following information is included with this letter: NPDES - Form 1. Attachment A. - Modified Application—Form 2A. Attachment B. Soils Evaluation report by Walker Ferguson, LSS of Land Resource Management, PLLC. Attachment C. Correspondence from USGS. Attachment D. - Correspondence from NCNHP. AttachmentE. - Stream Classification.Attachment F. Flow Path to"Blue Line"Water Feature.Attachment G. - Information on connection to Regional Sewer System.Attachment H. Engineering Alternatives Analysis(EAA).Attachment I. - Local Government Review Forms. Attachment J. - Topography Map(per 40 CFR 122.21(0(7)). Attachment K. Process Flow Diagram. Attachment L. Nearby Facilities Discharge Limits.Attachment M. The proposed discharge point is an unnamed tributary of Cane Creek on the subject property. The discharge system will utilize the following components: New Septic Tanks with Effluent Filter and/or new STEP systems 2X AdvanTex AX-100 Treatment Pod - 3X AdvanTex AX-20 Treatment Pod Re-circulation Tank UV Disinfection - Flow Meter - Discharge Point with Rip-Rap The proposed system will be comprised of two Phases. Phase 1 involves the installation of 1 AX-20, 1 AX-100, a 2,500 gal grease tank, 5,000 gal septic tank, 8,000 gal recirculation tank, pump vault, and a UV unit for the Event Center and Kitchen. Phase 2 will consist of the installation of the collection sewer for the cabins and a 2,500 gal septic tank that will feed into the recirculation tank. Additional treatment units for Phase 2 include the installation of 2 AX-20 treatment pods and a second AX-100 treatment pod. NPDES- Form 1 As part of Form 1, the feasibility of alternatives to discharging must be addressed. The following alternatives are to be evaluated: - Connection to a regional or municipal sewer collection system. - Letter from the local or county health department describing the suitability or non-suitability of the site for all types of wastewater ground adsorption and innovative non-discharge systems, as well as documenting the repair potential of the failed system. Investigate land application such as spray irrigation or drip irrigation. Modified Application—Form 2A As part of Form 2A, monitoring Table A was completed. The facility is proposed, so no site-specific effluent could be tested. The provided data is the average pollutant levels from upstream and downstream domestic facilities. Investigate Land Application such as spray irrigation or drip irrigation. Per the soil evaluation by Walker Ferguson, LSS of Land Resource Management,the site does not have suitable soil to accommodate a non-discharge surface spray or drip wastewater system (Attachment C). Based on the map provided, the majority of the property is unsuitable for septic permitting. 7Q10&30Q2 Flow Estimates The United States Geological Survey (USGS) was contacted to determine the 7Q10 and 30Q2 flow estimates for the proposed wastewater discharge point. The proposed discharge point is an unnamed tributary to Cane Creek. The analysis from USGS indicates both the 7Q10 and 30Q2 discharge for the point in question are positive The annual low-flow yields for the 7Q 10 is about 0.31 cfsm, and the annual low-flow yields for the 30Q2 for 0.58cfsm(Attachment D). Endangered Species Information The NC Heritage Program was contacted to gather endangered species information. One freshwater fish, Percina burtoni, is listed as being within a one-mile radius of the property, however it is listed as no longer occurring in this region. No species were found within the project area that hold federal endangered status(Attachment E). Flow Path to"Blue Line"Water Feature The discharge point is a unnamed tributary of Crane Creek located on the applicants property. A map showing the path from the discharge point to the first "blue-line" stream, as shown on the NC DEQ Stream Classification Map, can be seen in(Attachment G). Receiving Stream Crane Creek Stream Class C Connection to a Regional or Municipal Sewer Collection System Connection to a sewer collection system will likely not be available. Correspondence from Buncombe County Metropolitan Sewerage District (MSD) Planning & Development indicates that there were no lines in the area. A MSD map showed that the nearest sewer system to the applicants property is 3.96 miles. At an estimated cost of $150/ft, the cost to extend the sewer line would be $3,136,320 (plus engineering and tap fees) (Attachment H). Engineering Alternatives Analysis An Engineering Alternatives Analysis (EAA) has been completed for this site and is included as (Attachment I). The completed EAA demonstrates that a wastewater treatment system permitted as an Individual Discharge is the only feasible option for this site. We have exhausted all other options for this site as follows: a.) connection to a municipal or regional sewer collection system - Not feasible due to costs (at the present time). b.) subsurface disposal - Inadequate soil for a subsurface absorption system. c.) wastewater irrigation (drip and spray) - Inadequate soil and not feasible due to fill soil costs for a non-discharge ground absorption system. d.) reclaimed-water systems - Inadequate soil and not feasible due to fill soil costs for a reclaimed water system. No reasonable ability to operate as a bulk distributor of reclaimed water. e.) Any viable combination of the above - There are no viable combinations of the above due to soil and cost limitations. Local Government Review Forms As part of the EAA, Local Government Review Forms were sent to Buncombe County and the City of Fletcher. A copy of the form submittals is included as Attachment J. Both signed copies have been received and are attached. Topography Map A topographic map(per 40 CFR 122.21(0(7))is included as Attachment K. Process Flow Diagram A process flow diagram for the proposed system is included as Attachment L. Suggested Permit Compliance Limits Suggested permit limits are based on the limits of both upstream and downstream neighboring facilities. An existing facility, Flesher's Fairview Rest Home, is located 3.2 miles upstream of the proposed facility location, with a permitted daily discharge of 35,000 GPD. Located 1.2 miles downstream of the proposed facility is Cane Creek Middle School with a permitted daily discharge of 12,000 GPD. The BOD and TSS values are based on the average values of the permitted concentrations of these facilities. The Fecal Coliform value is based on the Cane Creek impairment limits(Attachment M). Effluent Characteristics Limits Monthly Average Daily Max Flow 6,000 gpd 6,000 gpd BOD, 5-day 30.0 mg/L 45.0 mg/L Total Suspended Soils 30.0 mg/L 45.0 mg/L Fecal 200 MPN/100 mL 400 MPN/100 mL I appreciate your time and efforts in reviewing this application.

The purpose of the soil and site investigation was to determine any available options for an on-site wastewater septic system to service an event venue/rental cabin. Recommendations are based on,but not limited to,observations made and data collected on topography, landscape position,parent material,underlying geology,and soil characteristics. Soil characteristics include,but are not limited to,depth to a seasonal high-water table(SHWT),depth to a restrictive horizon,total soil depth,soil horizonation,soil structure,soil color,clay mineralogy,bulk density,consistence,plasticity,stone content,and percent sand,silt,clay,and mica. They follow the guidelines set forth in the North Carolina Laws and Rules for Sewage Treatment and Disposal Systems,Subchapter 18E- Wastewater Treatment and Dispersal Systems. 1 RESULTS AND DISCUSSION • LRM found the lot to be unsuitable for any subsurface on-site wastewater disposal(septic) system. The site contains unsuitable soil conditions. Massive soil structure and shallow Seasonal High-Water Table(SHWT)depths were observed throughout the property. Therefore,LRM concludes that there are no subsurface septic system options available for this parcel. LRM appreciates the opportunity to provide this report.Please do not hesitate to call with any questions or concerns.

No USGS discharge records are known to exist for the point of interest. In the absence of site-specific discharge records sufficient for a low-flow analysis,estimates of low-flow characteristics at ungaged locations are determined by assessing a range in the low-flow yields(expressed as flow per square mile drainage area, or cfsm) at nearby sites where estimates have been determined. A basin delineation completed using the online USGS StreamStats application for North Carolina (https://streamstats.usgs.gov/ss/) indicates the drainage area for the point of interest(StreamStats adjusted coordinates 35.48371, -82.42897 NAD83) is 0.85 sqmi,which confirms the drainage area submitted as part of the request information. t For streams in Buncombe County, low-flow characteristics published by the USGS are provided in the following reports: (1)The first is a statewide report completed in the early 1990's. It is USGS Water-Supply Paper 2403, "Low-flow characteristics of streams in North Carolina" (Giese and Mason, 1993). An online version of the report is available at http://pubs.usgs.gov/wsp/2403/report.pdf. The report provides the low-flow characteristics (based on data through 1988)via regional relations and at-site values for sites with drainage basins between 1 and 400 sqmi and not considered or known to be affected by regulation and/or diversions. (2)The second is a statewide report published in March 2015. It is USGS Scientific Investigations Report 2015-5001, "Low-flow characteristics and flow-duration statistics for selected USGS continuous-record streamgaging stations in North Carolina through 2012 (Weaver, 2015). The report is available online at http://pubs.usgs.gov/sir/2015/5001/. The report provides updated low-flow characteristics and flow-duration statistics for 266 active (as of 2012 water year) and discontinued streamgages across the state where a minimum of 10 climatic years discharge records were available for flow ganalyses. Low-flow characteristics estimated for point of interest: For the record:There are very limited USGS streamflow records for small to very small basins in North Carolina. Inspection of the reports indicates the presence of ten (10) nearby selected USGS partial-record sites(8)and continuous-record streamgages (2)across southern Buncombe County and northern Henderson County in general vicinity of the point of interest where low-flow characteristics have previously been published. Among these 10 index sites,the low-flow discharge yields for the indicated flow statistics are as follows: Annual 7Q10 low-flow yields==>from 0.094 to 0.67 cfsm (average about 0.31 cfsm, median about 0.26 cfsm) Annual 30Q2 low-flow yields==>from 0.25 to 0.91 cfsm (average about 0.58 cfsm, median about 0.55 cfsm) Winter 7Q10 low-flow yields==>from 0.15 to 1.3 cfsm (average about 0.46 cfsm, median about 0.37 cfsm) Annual 7Q2 low-flow yields==>from 0.19 to 1.1 cfsm (average about 0.53 cfsm, median about 0.45 cfsm) Average annual discharge yields==>from 1 to 2.5 cfsm (average about 1.4 cfsm, median about 1.3 cfsm) Application of the above range in yields to the drainage area (0.85 sqmi)for the point of interest results in the following estimated low-flow discharges: Annual 7010 low-flow discharges==>from 0.08 to 0.57 cfs (average about 0.26 cfs, median about 0.22 cfs) Annual 30Q2 low-flow discharges==>from 0.21 to 0.77 cfs(average about 0.49 cfs, median about 0.47 cfs) Winter 7Q10 low-flow discharges==>from 0.13 to 1.1 cfs(average about 0.39 cfs, median about 0.31 cfs) Annual 7Q2 low-flow discharges==>from 0.16 to 0.94 cfs(average about 0.45 cfs, median about 0.38 cfs) Average annualdischarge discharges==>from 0.85 to 2.1 cfs(average about 1.2 cfs, median about 1.1 cfs) Please note: (1)The estimated flows are provided in units of cubic feet per second (cfs). (2)The low-flow yields provided above are rounded to 2 significant figures. Estimated low-flow discharges less than 1 cfs are rounded to 2 significant figures. If between 1 and 100 cfs, then rounded to 1 decimal place; if greater than 100, then rounded to the nearest whole number(zero decimal places).

Salem St. Apex, NC 27502 RE: Sandoval Farm Dear Julie Davidson: The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. Based on the project area mapped with your request, a query of the NCNHP database indicates that there are no records for rare species, important natural communities, natural areas,and/or conservation/managed areas within the proposed project boundary. Please note that although there may be no documentation of natural heritage elements within the project boundary, it does not imply or confirm their absence:the area may not have been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists. In the event that rare species are found within the project area, please contact the NCNHP so that we may update our records. The attached 'Potential Occurrences' table summarizes rare species and natural communities that have been documented within a one-mile radius of the property boundary. The proximity of these records suggests that these natural heritage elements may potentially be present in the project area if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one-mile radius of the project area, if any,are also included in this report. If a Federally-listed species is found within the project area or is indicated within a one-mile radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here: httos://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37.

Determine if the proposed discharge will be allowed Determination of whether the proposed wastewater discharge will be allowed. There are several potential restrictions to a wastewater discharge to surface waters,including: ■ Zero flow stream restrictions [15A NCAC 2B.0206(d)(2)] apply to oxygen-consuming waste in zero-flow streams. In order to determine streamflow at the P proposed osed discharge location, contact the U.S. Geological Survey at 919-571-4000. Response: The USGS was contacted for streamflow estimations for the tributary of Cane Creek. There is positive flow for the 7Q10 and 30Q2 stream estimates. • Receiving stream classification restrictions [e.g., ORW, WS, SA, NSW, and HQ class waters have various discharge restrictions or require stricter treatment standards]. Stream classifications are available on the the DWR Classification and Standards/Rule Review Branch website: (http://portal.ncdenr.org/web/wq/ps/csu), while wastewater discharge restrictions for various stream classifications are presented in state regulations [15A NCAC 2B.0200]. Response: The DWR Surface Water Classification for Cane Creek is C. • Basinwide Water Quality Plans. These basin-specific plans list NPDES permitting strategies that may limit wastewater discharges to particular streams within the basin due to lack of stream assimilative capacity,etc. Basin plans are available on the DWR website,or you may contact the DWR Basinwide Planning Branch (http://portal.ncdenr.org/web/wq/ps/bpu). Response: Cane Creek is within the French Broad River Basin. • Impaired waters and TMDLs. Certain waterbodies listed as impaired on the 303(d) list and/or subject to impending TMDLs may have wastewater discharge restrictions. The list of 303(d) impaired waters is located on the DWR website, or you may contact the DWR Modeling and Assessment Branch (http://portal.ncdenr.org/web/wq/ps/mtu). Response: Cane Creek is an impaired water according to DWR Modeling and Assessment Branch. The proposed system will be meeting the requirements of the impairment. • Presence of Endangered Species. If endangered species are present in the proposed discharge location, there may be wastewater discharge restrictions. Endangered species information may be included in the Basinwide Water Quality Plan, or you may contact the U.S. Fish and Wildlife Service(919-856-4520),N.C.Wildlife Resources Commission (919-733-3633), or the N.C.Natural Heritage Program(919-733-7701). Response: The NC Heritage Program was contacted to gather endangered species information.No species were found on the subject property that held federal or state endangered status.No species within a 1 mile radius of the project area held federal endangered status. While the Blotchside Logperch was listed as endangered the NC Heritage Program indicated that the occurrence has been destroyed. Within the one-mile radius of the property, the NC Heritage Program indicated the following Species Federal and State Status: EAA Guidance Document Revision:April 2014 Page 1 of 10 - Eastern Hellbender(Amphibian)—State Status:Special Concern - Blue-winged Warbler(Bird)—State Status:Significantly Rare - Banded Sculpin(Freshwater Fish)—State Status:Special Concern - Blotched Chub (Freshwater Fish')—State Status:Threatened - Blotchside Logperch (Freshwater Fish)—State Status: Endangered - Prickly Ground-pine (Vascular Plant)—State Status: Significantly Rare Peripheral Non-municipal applicants. Due to staff constraints, the NPDES Unit cannot prepare speculative limits for non-municipal applicants. Thus,it is your responsibility to make your own determination as to whether the proposed discharge might be allowed by the Division, by evaluating the water quality factors listed above. It is highly recommended that you discuss the proposed discharge with the applicable DWR Regional Office and/or NPDES Unit staff,who may be able to provide input on the likelihood of a new/expanding discharge. As a first step, you must obtain streamflow estimates for the proposed discharge location to ensure that the receiving stream is not subject to zero flow restrictions. Low flow data (specifically, drainage area, the summer and winter 7Q10, average flow and 30Q2 flow statistics) can be obtained for a nominal fee from the U.S. Geological Survey in Raleigh at 919-571-4000. The low flow data must be submitted with the EAA, and will be used by the permit writer to develop permit limits. You must also verify that the proposed action (i.e., construction of a wastewater treatment plant and its appurtenances) is consistent with local zoning and/or subdivision ordinances. You will need to request the local government(s) to complete a Local Government Review Form (Attachment A),and include the signed and notarized form with your NPDES application package. Response: The United States Geological Survey (USGS)was contacted to determine the 7Q10 and 30Q2 flow estimate for the downstream tributary of the proposed wastewater discharge point. The proposed discharge point is a tributary of Cane Creek. The analysis from USGS indicates the 7Q10 and 30Q2 discharge for the point in question is positive for both flow estimates(Attachment E of application package). All applicants. If you conclude that the proposed discharge will pass the "allowable discharge" criteria, then begin the EAA preparation by summarizing the following general information about the proposed project: ■ Provide a description of the proposed project. If the project will be constructed in phases, provide a schedule for constructing each additional phase,and provide the projected flow per phase (see STEP 2). Response: A wastewater discharge system is to be constructed for an event center located in Buncombe County, North Carolina. The proposed system will serve a kitchen with a flow of 3,500 gallons per day combined with 10 cabins with a flow of 2,400 gallons per day for a total flow of 6,000 gallons per day. The proposed discharge point is in a tributary of Cane Creek, located on the applicant's property. The proposed treatment system will utilize the following components: - 1 x 2,500 Gal Septic Tank With Effluent Filter - 1 x 2,500 Gal Grease Tank 1 x 5,000 Gal Septic Tank with Effluent Filter 1 x 8,000 Gal Recirculation tank 3 x AdvanTex AX-20 - 2 x AdvanTex AX-100 UV Disinfection Pump Vault Flow Meter Discharge Point with Rip-Rap EAA Guidance Document Revision:April 2014 Page 2 of 10 Construction of the proposed system will occur in two phases with an estimated completion time of two months after the start of construction activity for each phase. Phase I involves the installation of 1 AX-20, 1 AX-100, a 2,500 gal grease tank, 5,000 gal septic tank,8,000 gal recirculation tank,pump vault,and a UV unit for the Event Center and Kitchen. Phase 2 will consist of the installation of the collection sewer for the cabins and a 2,500 gal septic tank that will feed into the recirculation tank. Additional treatment units for Phase 2 include the installation of 2 AX-20 treatment pods and a second AX-100 treatment pod.

Provide reasonable projections for population and flo w Residential Population Projections. Facilities requesting an NPDES discharge permit for new or expanding domestic wastewater discharges must document the population to be served within the service area over a 20-year planning period. The NC State Demographics unit provides population data for each county and municipality and can be accessed on the Internet at http://www.demog.state.nc.us. If 20-year population projections for specific areas are not available, a linear extrapolation of population trends from the past decade should be used. Any deviation from a linear projection method must be clearly justified. If population projections include future annexations, include a proposed annexation schedule as well as any annexation requirements that must be met. Response: The wastewater treatment system is designed for an event center with kitchen and 10 cabins. Flow for the event center with kitchen will be limited by the number of seats while the cabins will be limited by the number of bedrooms. For the 20-year planning period,the system will be designed for a 300 seat kitchen with a flow of 12 gallons per day per seat combined with 10 cabins with a flow of 240 gallons per day. The design flow is 6,000 gallons per day for the facility. STEP 3. Evaluate technologically feasible alternatives Alternative A. Connection to an Existing Wastewater Treatment System. EAA Guidance Document Revision:April 2014 Page 3 of 10 You must evaluate the feasibility of connecting to an existing wastewater treatment system served by a municipality or other entity holding a valid NPDES or Non-Discharge Permit. All connection options should include an evaluation of a gravity line and/or force main with pump station(s). 1. Existing Sewerage System: (a) Identify whether there are existing sewer lines within a five-mile radius,or consider a greater radius if cost effective for the project size. Response: Connection to a sewer collection system is not feasible for this facility. Ms. Heather Rhinehart, System Coordinator II Metropolitan Sewerage District—Engineering Division,did not indicate that sewer is available or any plans to extend the sewer at this time There are currently no lines in the area with the closest sewer system located approximately 3.96 miles from the applicant's property (Attachment I). For reference, if an installation cost of$150/ft of installed sewer line was assumed, the cost to connect this property to the sewer line would exceed$3,136,320.Additional costs including the cost of the pump station, potential "tap"or sewer capital fees, road repair costs,frontage fees and fees for right of way permits would also be incurred by the owner. (b) Provide a preliminary indication of flow acceptance from existing municipal or private WWTPs under consideration for connection. If a municipal or private WWTP cannot accept the wastewater, include a letter documenting such and consider this alternative technologically infeasible. Response: N/A No sewerage available (c) If an existing sewerage system will accept the wastewater, evaluate the piping/pumps/resources necessary to connect to the existing wastewater treatment plant. Attach a topographic map or a site drawing showing the physical route of this alternative. Conduct a Present Value Cost Analysis per STEP 4. Response: N/A No sewerage available 2. Planned Sewerage System: Determine if a regional sewerage system within a five mile radius is projected to be available within the next five years to receive waste from the project site. If applicable, determine availability date and flow acceptance projection from appropriate authority. Response: As indicated above, a regional sewer system exists within a five mile radius of the applicant's property, but the Metropolitan Sewerage District did not indicate any plans to extend their coverage area toward the applicant. Alternative B. Land Application. Land application disposal alternatives include individual/community onsite subsurface systems, drip irrigation,and spray irrigation. 1. Provide an estimate of the best case hydraulic loading rate based on County Soil Surveys or from a soil evaluation performed by a soil scientist. Include calculations showing the hydraulic loading rate and the total area of land needed for the land disposal system,including buffers. Response: Per the soil evaluation by Walker Ferguson, LSS of Land Resource Management, PLLC, the site does not have suitable soil or space to accommodate the daily flow necessary using a ground absorption wastewater system (Attachment D of application package). Regardless of the fact that a subsurface ground absorption cannot be designed or permitted for this site, the potential size of a subsurface system has been estimated. These soils would have a long-term acceptance rate (LTAR) ranging from 0.05-0.15 gpd/sq.ft., with a typical rate of 0.1 gpd/sq.ft. Subsurface systems also require the drainline to be installed with the contour so that each drainline is at a constant elevation. This results in a "fanning"of the drainline and requires additional space in order to install the required amount of drainline. The sizing calculation is summarized in the table below: EAA Guidance Document Revision:April 2014 Page 4 of 10 Subsurface Dripfleld Design Alternative Daily Flow 6000 gpd LTAR 0.1 gpd/sqft Minimum Area Required (Nominal) 60,000 sqft =Day Flow/LTAR Estimation for Topographical Variation 20,000 sqft Estimated Area Required (Actual) 80,000 sqft Approximate Area Available 157,406 sqft The current property's land available for the system is 157,406 sqft, due to setbacks and existing site conditions. A schematic of this area is shown in Appendix A of the EAA. The land needed for a subsurface dripfield design is a minimum of 80,000 sq. ft. Although there may be sufficient space, due to limitations caused by the soil characteristics and conditions,this property is not suitable for a subsurface system. The potential size of a non-discharge surface application system has also been estimated. According to the county soil survey, the site is classified as a Worsham series soil. For a surface system in this soil, the SFR loading rate group is likely restricted to a maximum annual loading of 19.5 in/year. The sizing calculation for a non-discharge surface system is summarized in the table below: Non-Discharge Surface Design Alternative Daily Flow 6000 gpd Surface Loading Rate 19.5 in/year Minimum Area Required (Nominal) 180,162 sqft Approximate Area Available 75,268 sqft The current property's land available for a surface drip or spray system is 75,268 sqft, due to setbacks and existing site conditions. The major limiting factors that prevent this type of system are the 100' stream setback, the 50' property setback, and the location of future tiny homes as well as the 15' foundation setback associated with them. A schematic of this area is shown in Appendix A. The land needed for a non-discharge application system is estimated at 180,162 sq.ft. so there is not a suitable amount of land. 2. Assess the availability of land. If insufficient land is available onsite, assume that the necessary land can be purchased and estimate the land purchase cost based on local real estate prices. Alternatively,provide documentation to demonstrate that insufficient land is available for sale in the project area (include letters from adjacent property owners indicating no interest in selling property). Response: Because insufficient land is available onsite (due to inadequate soil) offsite land was reviewed. The table below lists neighboring properties and the value of the land as listed by the Buncombe County GIS website. The values listed in the table do not reflect the value of the single-family residences. While there is vacant lots there is no guarantee they would be able to be purchased and they are likely to have the same soil restrictions on the subject property. These sites, like the applicant's site, will be very restrictive for wastewater systems EAA Guidance Document Revision:April 2014 Page 5 of 10 due to the setbacks. Much of the listed southern and northern parcels are restricted for septic application by topography.

Provide a description of the wastewater treatment system and the non-discharge application system. Include a site plan showing the proposed layout, the application area, any existing structures,proposed structures, and other uses within the site. Response: A typical subsurface drip system or a non-discharge surface spray or surface drip system with pretreatment considers the following components: -Septic Tank with Effluent Filter -Recirculation Tank -AdvanTex Treatment Pod(AX100 unit) -Pump Tank -UV Disinfection -Headworks Box -Control Panel -Disposal Field(drip or spray)with addition of fill soil Note: The proposed discharge system does not consider the pump tank,headworks box or disposal field. Site drawings of these alternative systems showing the available application area are included as Appendix A of the EAA. Due to the cost requirements of a drip or spray system and the lack of sufficient soil,there is no ability to consider any of these systems on this property. 4. Explain the proposed reuse plan if reclaimed water will be used by a third party. Response: There is no reuse plan being considered either on-site or by a third party. It is not feasible to consider using reclaimed water on the site or becoming a bulk distributor of reclaimed water. The table below summarizes the amount of reclaimed water that could be beneficially used on site. As shown in Appendix A, there is insufficient space to support a reclaimed water system.

Conduct a Present Value Cost Analysis per STEP 4. For the reclaimed water system include the potential revenue generated by selling the water. Response: A Present Value Cost Analysis is included as Appendix B of the EAA. An analysis was performed for a sub-surface drip system, a non-discharge surface application system, and a reclaimed water system. A summary of the analysis is included in STEP 4. 6. Provide all calculations, documentation and maps as necessary to support assumptions and conclusions. Response: Calculations performed to evaluate land application alternatives are shown above in Alternative B, Points 1 and 4. 7. Note: The design of land application systems must meet the treatment and design requirements specified in 15A NCAC 2T .0500 or 15A NCAC 18A.1900. Response: The treatment systems specified above in Step B would meet the treatment standards required by these rules as they pertain to single family residences. However, due to the restrictions listed above, no land-based systems can be considered. 8. Note: Proposed discharges from groundwater remediation systems must evaluate the potential for an infiltration gallery treatment alternative. Response: N/A Alternative C. Wastewater Reuse. You must evaluate reusing all or a portion of the wastewater generated. Some municipalities are currently reusing wastewater within the confines of their WWTP property for irrigation, toilet flushing, backwashing, etc.,while other municipalities have established progressive reuse programs for residential irrigation. Reuse applications might include golf course irrigation, crop irrigation (e.g., hardwood or pine plantation, grasses), athletic field irrigation, landscape uses, and commercial/industrial uses. Some of these reuse applications will be evaluated under Alternative B, Land Application. The design of reclaimed water systems must meet the treatment and design requirements specified in 15A NCAC 2U. Response: All reuse applications for this project scale were evaluated under Alternative B,Point 4. Wastewater reuse was determined to be infeasible for this project. EAA Guidance Document Revision:April 2014 Page 7of10 Alternative D. Direct Discharge to Surface Waters. 1. No new or expanding (additional) discharge of oxygen-consuming waste will be allowed to surface waters of North Carolina if both the summer 7Q10 and 30Q2 streamflows are estimated to be zero,in accordance with 15A NCAC 2B.0206(d). Private applicants must contact the USGS in Raleigh at 919-571-4000 and obtain (generally for a nominal fee),the receiving streamflow data (s7Q10,30Q2, annual average streamflow) at the proposed discharge location. This information must be included in the EAA,and will be used to develop permit limits. Response: Because this is a new treatment facility, estimated flow at the discharge point is required to be positive. Based on the 7Q10 and 30Q2 reports provided by USGS, the flow is expected to be positive. The average for the 7Q10 was about 0.26 cfsm and the average for the 30Q2 was about 0.49 cfsm. 2. All direct discharge systems of oxygen-consuming wastes should be evaluated both with tertiary filtration [BOD5= 5 mg/1, NH3-N= 1 mg/1] and without, and assuming a weekly sampling regime. Response: Tertiary filtration is not required. Based on actual sample results from similar treatment systems (other facilities using the same technology)in many cases,a BOD5 of 5 mg/1 and NH3-N of 1 mg/1 can be met. 3. Provide a description of the proposed wastewater treatment facilities, including a schematic diagram of the major components and a site plan of the treatment facility with outfall line(s). Response: Schematic drawings can be found in Attachment M(of application package). 4. Provide documentation of the availability of required land and/or easement agreements. Response: N/A 5. Conduct a Present Value Cost Analysis per STEP 4. Response: A Present Value Cost Analysis for the discharge system is included in Appendix B. A summary of the analysis is included in STEP 4. 6. Note: All direct discharge treatment systems must comply with Reliability Requirements specified in 15A NCAC 2H.0124. Response: The system serves a private facility that is served by an onsite well and does not have elevated water storage tanks. In the event of a power outage,water will not be available to the cabin and kitchen. There is storage available in the system to hold some waste until power is restored to the system. Alternative E. Combination of Alternatives. You should evaluate the possibility of a combination of wastewater alternatives that would minimize or eliminate a direct discharge alternative. For example, consider whether the facility can operate a land application system during the dry season when streamflows are at their lowest and provide less dilution,and operate an NPDES discharge system during the wet season when soils may not be as amenable to land application and the receiving stream provides its greatest dilution. Response: A non-discharge alternative is not feasible due to the space and soil constraints listed in Alternative B. The presence or absence of a seasonal high water table will not relieve the other constraints. EAA Guidance Document Revision:April 2014 Page 8 of 10 STEP 4. Evaluate economic feasibility of alternatives PVCA Summary Table. The EAA must include a Summary Cost Table, which summarizes present worth costs developed for all technologically feasible wastewater alternatives. The summary should include a breakdown of capital costs and recurring costs. In some situations, the Division may require the applicant to refine cost estimates for some alternatives, or possibly collect actual soil data to better characterize the land application alternative. Ultimately, the final determination on cost effectiveness is made by the Division with consideration of monetary costs as well as potential environmental impacts. Response: The following table presents the cost analysis for several types of wastewater systems. Given the information presented above,the only technologically feasible alternative is the Discharge System. The "Install Cost"includes the estimated cost to design and install the specific type of system. The installation cost does not include the cost of fill soil that would likely need be added,at the direction of a L.S.S.,to maintain suitable soil depths within a drainfield. The"Present Value of Costs"is based on a discount factor of 2.5%.

Local Government Review Form General Statute Overview: North Carolina General Statute 143-215.1 (c)(6)allows input from local governments in the issuance of NPDES Permits for non-municipal domestic wastewater treatment facilities. Specifically, the Environmental Management Commission (EMC) may not act on an application for a new non-municipal domestic wastewater discharge facility until it has received a written statement from each city and county government having jurisdiction over any part of the lands on which the proposed facility and its appurtenances are to be located. The written statement shall document whether the city or county has a zoning or subdivision ordinance in effect and (if such an ordinance is in effect) whether the proposed facility is consistent with the ordinance. The EMC shall not approve a permit application for any facility which a city or county has determined to be inconsistent with zoning or subdivision ordinances unless the approval of such application is determined to have statewide significance and is in the best interest of the State. Instructions to the Applicant: Prior to submitting an application for a NPDES Permit for a proposed facility, the applicant shall request that both the nearby city and county government complete this form. The applicant must: • Submit a copy of the permit application(with a written request for this form to be completed) to the clerk of the city and the county by certified mail,return receipt requested. • If either (or both) local govemment(s) fail(s) to mail the completed form,as evidenced by the postmark on the certified mail card(s),within 15 days after receiving and signing for the certified mail,the applicant may submit the application to the NPDES Unit. • As evidence to the Commission that the local governments) failed to respond within 15 days,the applicant shall submit a copy of the certified mail card along with a notarized letter stating that the local government(s) failed to respond within the 15-day period. Instructions to the Local Government: The nearby city and/or county government which may have or has jurisdiction over any part of the land on which the proposed facility or its appurtenances are to be located is required to complete and return this form to the applicant within 15 days of receipt. The form must be signed and notarized.

Fletcher, NC 28732 RE: Local Government Review Form Application for Discharge System—Sandoval Farm Event Center LLC. 5 Greene Ln, Fletcher,NC 28732 Dear Mr. Biberdorf, Enclosed please find a Local Government Review Form required for a Certificate of Coverage application supporting a proposed wastewater treatment system. The proposed system will be an Individual Discharge Permit that is permitted under the NPDES Permitting Program. The proposed system will serve a proposed Event center located in Buncombe County,North Carolina(nearby the Town of Fletcher). It is my opinion that a wastewater treatment system covered by the Individual Discharge Permit is the only technologically feasible option for this property. The site has been deemed unsuitable for ground absorption and unable to meet the required daily flow by a licensed soil scientist. Please complete the enclosed form for inclusion in the application for the proposed system. The property is located in Buncombe County. Please note that this form is only meant to determine zoning/jurisdiction information for the county and does not indicate your approval of the proposed system. I appreciate your time and efforts in completing this form. If you have any questions or comments,please feel free to contact me at 919-859-0669. Best Regards, Scott P. Jones, P.E.
