Salem Street, Suite 203 Apex, North Carolina 27502 919-859-0669 www.agriwaste.com Ms. Sydney Carpenter NPDES Permitting Program Division of Water Quality 1617 Mail Service Center Raleigh, North Carolina 27699-1617 RE: Application for Individual NPDES Discharge System — Broch Property Lower Beaverdam Loop Road, Candler, NC 28715 (PIN: 9605-25-0161) Dear Ms. Carpenter, July 28, 2021 Enclosed please find information supporting an application for a new individual NPDES discharge system for a proposed tiny home village located in Buncombe County, North Carolina. The tiny home village will consist of ten (10) tiny homes and a communal bath house. The site has been deemed unsuitable for ground absorption sewage treatment systems by the Buncombe County Environmental Health due to unsuitable soil wetness conditions, unsuitable soil depth, and insufficient space. The proposed system is to be sized for 2,400 gallons per day and has been designed to convey all wastewater from the proposed facilities, including greywater, to the new septic tank. 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. Documentation From Buncombe County Health Department. Attachment C. Soils Evaluation report by Walker Ferguson, LSS of Land Resource Management, PLLC. AttachmentD. Correspondence from USGS. AttachmentE. Correspondence from NCNHP. Attachment F. Stream Classification. Attachment G. Flow Path to "Blue Line" Water Feature. Attachment H. Information on connection to Regional Sewer System. Attachment I. Engineering Alternatives Analysis (EAA). Attachment J. Local Government Review Forms. AttachmentK. Topography Map (per 40 CFR 122.21(f)(7)). Attachment L. Process Flow Diagram. Attachment M. The proposed discharge point is Beaverdam Creek, located along Lower Beaverdam Loop Road. The discharge system will utilize the following components: New Septic Tanks with Effluent Filter and/or new STEP systems AdvanTex AX-100 Re -circulation Tank UV Disinfection Flow Meter Discharge Point with Rip -Rap 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 deparlment 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 that was sampled from ten (10) comparable facilities. 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. Document the repair potential of the failed system. The Buncombe County Health Depailment indicated that the site is unsuitable for installation of a ground absorption septic system in letter dated May 24, 2021 (Attachment C). The letter indicated that an improvement permit cannot be issued due to unsuitable soils. 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 D). Based on the map provided, the majority of the property is unsuitable for septic permitting. There an area (borings 4, 5, and 13) that has potential for non -discharge permitting, but size and stream proximity, 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 Beaverdam Creek. The analysis from USGS indicates both the 7Q10 and 30Q2 discharge for the point in question are positive (Attachment E). Endangered Species Information The NC Heritage Program was contacted to gather endangered species information. No species were found within a one -mile radius of the property that held federal or state endangered status. One vascular plant, Virginia Spiraea, may be located within the project area that holds federal and state endangered status. Flow Path to "Blue Line" Water Feature The discharge point is a portion of Beaverdam Creek that is on the applicant's 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 H. Receiving Stream Beaverdam Creek Stream Class C; Tr Connection to a Regional or Municipal Sewer Collection System Connection to a sewer collection system will likely not be available. Correspondence from MSD Planning & Development indicates that the closest sewer system is in excess of 4 miles from the applicant's property. At an estimated cost of $100/ft, the cost to extend the sewer line would be $2,112,000 (plus engineering and tap fees). Engineering Alternatives Analysis An Engineering Alternatives Analysis (EAA) has been completed for this site and is included as Attachment J. 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 Asheville. A copy of the form submittals is included as Attachment K. To date, only one completed form has been received. Topography Map A topographic map (per 40 CFR 122.21(f)(7)) is included as Attachment L. Process Flow Diagram A process flow diagram for the proposed system is included as Attachment M. Suggested Permit Compliance Limits Suggested permit limits are based on the limits of a neighboring facility, comparable treatment systems, and The Upper French Broad River Subbasin Overview. BOD and TSS values are taken from the 2021 draft permit for Laurelwood Mobile Home Park, while Fecal values were determined from the general discharge permit, as well as data from facilities with comparable treatment technology. When determining the proposed compliance limits, the South Hominy Creek Subwatershed Overview was considered. Because of the following statement, "At Beaverdam and Warren Creeks, the fish communities were impacted by nearby land use practice. Nutrients did not seem to be an issue at any of the sites.", it was determined that this was not a nutrient sensitive subwatershed. Effluent Characteristics Limits Monthly Average Daily Max Flow 2,400 gpd BOD, 5-day Total Suspended Soils Fecal 30.0 mg/L 45.0 mg/L 30.0 mg/L 45.0 mg/L 200 MPN/100 mL 400 MPN/100 mL I appreciate your time and efforts in reviewing this application.

Beaverdam Loop Rd. Candler, NC 28715. Dear Ms. Kimberly Broch The Buncombe County Health and Human Services, Environmental Health Division on _5/24/21 evaluated the above -referenced property at the site designated on the plat/site plan that accompanied your application. According to your application the site is to serve numerous homes for a total of 20-bedrooms with a design wastewater flow of 2400 gallons per day. The evaluation was done in accordancc with the laws and rules governing wastewater systems in North Carolina General Statute 130A-333 and related statutes and Title 15A, Subchapter 18A, of the North Carolina Administrative Code, Rule. 1900 and related rules. Based on the criteria set out in Title 15A, Subchapter 18A, of the North Carolina Administrative Code, Rules .1940 through .1948, the evaluation indicated that the site is UNSUITABLE for a ground absorption sewage system. Therefore, your request for an improvement permit is DENIED. The site is unsuitable based on the following: Unsuitable soil topography and/or landscape position (Rule .1940) Unsuitable soil characteristics (structure or clay mineralogy) (Rule .1941) X Unsuitable soil wetness condition (Rule .1942) _X_ Unsuitable soil depth (Rule .1943) Presence of restrictive horizon (Rule .1944) _X_ Insufficient space for septic system and repair area (Rule .1945) Unsuitable for meeting required setbacks (Rule .1950) Other (Rule .1946) These severe soil or site limitations could cause premature system failure, leading to the discharge of untreated sewage on the ground surface, into surface waters, directly to ground water or inside your structure. The site evaluation included consideration of possible site modifications, as well as use of modified, innovative, or alternative systems. However, the Division of Environmental Health has determined that none of the above options will overcome the severe conditions on this site. A possible option might be a system designed to dispose of sewage to another area of suitable soil or off -site to additional property. For the reasons set out above, the property is currently classified UNSUITABLE, and no improvement permit shall be issued for this site in accordance with Rule .1948(c). Note that a site classified as UNSUITABLE may be classified as PROVISIONALLY SUITABLE if written documentation is provided that meets the requirements of Rule .1948(d). A copy of this rule is enclosed. You may P.O.

NC Weaver, John C <jcweaver@usgs.gov> Tue 9/8/2020 5:17 PM To: Julie Davidson <jpeele@agriwaste.com> Cc: dwrlowflows@ncdenr.gov <dwrlowflows@ncdenr.gov>; david.hill@ncdenr.gov <david.hill@ncdenr.gov>; klaus.albertin@ncdenr.gov<klaus.albertin@ncdenr.gov>;julie.grzyb@ncdenr.gov <julie.grzyb@ncdenr.gov>; adugna.kebede@ncdenr.gov <adugna.kebede@ncdenr.gov>; Weaver, John C <jcweaver@usgs.gov> Ms. Davidson, In response to your inquiry about the low -flow characteristics for a location on Beaverdam Creek at Beaverdam in southwestern Buncombe County, the following information is provided: A check of the low -flow files here at the USGS South Atlantic Water Science Center (Raleigh office) does not indicates a previous low -flow determination for the point of interest, identified by the lat/long coordinates (35.49441, -82.68926) provided via email dated 09/03/2020 from the DWR USGS Low Flow portal following your request submission. 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 previously 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 35.49441, -82.68926 NAD83) is 4.69 sqmi, which confirms the drainage area submitted as part of the request information. 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 https://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 https://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 analyses. Low -flow characteristics estimated for point of interest: Inspection of the reports indicates the presence of ten (10) nearby selected USGS partial -record sites (5) and continuous -record streamgages (5) in the general vicinity of the point of interest where low -flow 1 of 3 3/11/2021, 2:14 PM Firefox https://outlook.office.com/maiUsentitems/id/AAQkAGE5ODAwZGVjL... characteristics were 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 0.22 to 0.56 cfsm (average about 0.36 cfsm, median about 0.39 cfsm) Annual 30Q2 low -flow yields ==> from 0.43 to 1 cfsm (average about 0.73 cfsm, median about 0.76 cfsm) Winter 7Q10 low -flow yields ==> from 0.3 to 0.69 cfsm (average about 0.49 cfsm, median about 0.51 cfsm) Annual 7Q2 low -flow yields ==> from 0.36 to 0.87 cfsm (both average and median about 0.62 cfsm) Average annual discharge yields ==> from 1.1 to 3.2 cfsm (average about 2 cfsm, median about 2.4 cfsm) Application of the above range in yields to the drainage area (4.69 sqmi) for the point of interest results in the following estimated low -flow discharges: Annual 7Q10 low -flow discharges ==> from 1 to 2.6 cfs (average about 1.7 cfs, median about 1.8 cfs) Annual 30Q2 low -flow discharges ==> from 2 to 4.7 cfs (average about 3.4 cfs, median about 3.6 cfs) Winter 7Q10 low -flow discharges ==> from 1.4 to 3.2 cfs (average about 2.3 cfs, median about 2.4 cfs) Annual 7Q2 low -flow discharges ==> from 1.7 to 4.1 cfs (both average and median about 2.9 cfs) Average annual discharge discharges ==> from 5.2 to 15 cfs (average about 9.4 cfs, median about 11.3 cfs) Please note: (1) The estimated flows are provided in units of cubic feet per second (cfs).

Salem St. Apex, NC 27502 RE: Lucas Onsite Wastewater Design Lucas Dear Julie Davidson: Roy Cooper, Governor D. Reid Wilson, Secretary Walter Clark Director, Division of Land and WaterSlewardship NCNHDE-14446 The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. A query of the NCNHP database indicates that there are records for rare species, important natural communities, natural areas, and/or conservation/managed areas within the proposed project boundary. These results are presented in the attached `Documented Occurrences' tables and map. 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 documented within the project area or 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: https://www.fws.gov/offices/Di rectory/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 proposed discharge location, contact the U.S. Geological Survey at 919-571-4000. Response: The USGS was contacted for streamflow estimations for the portion of Beaverdam Creek from the discharge point to South Hominy 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 Beaverdam Creek is C; Tr. • 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: Beaverdam 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: Beaverdam Creek does not appear to be an impaired water according to DWR Modeling and Assessment Branch. • 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 within a one -mile radius of the property that held federal or state endangered status. One vascular plant, Virginia Spiraea, is expected to be located within the project area that holds federal and state endangered status. EAA Guidance Document Revision: April 2014 Page 1 of 8 Within the one -mile radius of the property, the NC Heritage Program indicates that other species have Federal or State status of the following: Eastern Hellbender (Amphibian) — State Status: Special Concern French Broad River Crayfish (Crustacean) — State Status: Significantly Rare Superb Jewelwing (Dragonfly or Damselfly) — State Status: Significantly Rare Little Brown Bat (Mammal) — State Status: Significantly Rare Northern Long-eared Bat (Mammal) — State & Federal Status: Threatened Virginia Spiraea (Vascular Plant) — State and Federal Status: Threatened 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 in Beaverdam 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 a tiny home village located in Buncombe County, North Carolina. The proposed system will serve 10 tiny homes with a flow of 2,500 gallons per day. The proposed discharge point is in Beaverdam Creek, located on the applicant's property. The proposed treatment system will utilize the following components: Septic Tank with Effluent Filter AdvanTex AX-100 Recirculation Tank Flow Meter UV Disinfection Discharge Point with Rip -Rap Construction of the proposed system will occur in a single phase with an anticipated completion time of approximately 2 weeks after the start of construction activity.

Agri -Waste Technology, Inc. 501 N. Salem Street Apex, NC 27502 919-859-0669 Kevin Davidson, P.E. STEP 2. Provide reasonable projections for population and flow 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 10 tiny homes, the population to be served will be limited by the number of homes. For the 20-year planning period, the system will be designed for a 10 tiny home village with a flow of 240 gallons per day per home. The design flow is 2,400 gallons per day for the facility. STEP 3. Evaluate technologically feasible alternatives Alternative A. Connection to an Existing Wastewater Treatment System. 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, indicated that sewer is not currently available for the applicant's property and there are currently no plans to extend the sewer. The closest sewer system is located approximately 4 miles from the applicant's property (Attachment I). For reference, if an EAA Guidance Document Revision: April 2014 Page 3 of 8 installation cost of $100/ft of installed sewer line was assumed, the cost to connect this property to the sewer line would exceed $2,112,000. 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 has no 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: The Buncombe County Department of Environmental Services indicated that the site is unsuitable for installation of a ground absorption septic system in a letter dated May 24, 2021 (Attachment C of application package). The letter indicated that a permit cannot be issued due to unsuitable soil wetness conditions, unsuitable soil depth, and insufficient space. Per the soil evaluation by Walker Ferguson, LSS of Land Resource Management, PLLC, the site does not have suitable soil or space to accommodate a ground absorption or surface drip or surface spray 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. According to the county soil survey, the site is classified as a Iotla Loam soil (IoA) and Rosman Fine Sandly Loam (RsA). These sandy loam soils are frequently flooded and very restrictive for wastewater systems. For a subsurface system in this soil, a drip system with pretreatment would be required. 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 8 Subsurface Dripfield Design Alternative # Tiny Homes Daily Flow 10 2400 gpd LTAR 0.1 gpolsgft Minimum Area Required (Nominal) 24,000 sqft Estimation for Topographical Variation 9,000 sqft Estimated .Area Required (Actual) 32,000 sqft Approximate Area .Available 166,111 sqft =fhv/L74 The current property's land available for the system is 166,111 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 24,000 sq. ft., so there may be sufficient space for this type of system at the residence. 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 # Bedrooms 20 Daily Flow 2400 gpd Surface Loading Rate 19.5 inlyear Minimum Area Required (Nominal) Approximate Area Available 72,065 sqft 84,969 sqft The current property's land available for a surface drip or spray system is 84,868 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 72,065 sq. ft., so while there is potentially enough space for this type of system, soil characteristics and conditions limit usage. 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. The soil types listed for these properties are Evard-Cowee Complex (EvE2) and Clifton Clay Loam (CkE2). These sites, like the applicant's site, will be very restrictive for wastewater systems. Much of the listed southern and northern parcels are restricted for septic application by topography and unnamed tributaries of Beaverdam Creek. EAA Guidance Document Revision: April 2014 Page 5 of 8 3. 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 (AX 100 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 may be sufficient area to utilize the daily flow of reclaimed water. Although there may be sufficient space, due to limitations caused by the soil characteristics and conditions, this property is not suitable for on -site utilization of reclaimed water. Regardless of the fact that the soil at this site is not suitable for this system, installing this system would not be feasible due to costs. On -site Utilization of Reclaimed Water Daily flow through system Available Area to Irrigate Application Rate Acceptable Volume to Irrigate. 2400 gpd 2110,3114 sgft 't r. cope -von pa rtv 0.5 in/week Fesc morass 8753 fefweek = 9365 gpd 5. 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. EAA Guidance Document Revision: April 2014 Page 6 of 8 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. 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 an 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 1.7cfsm and the average for the 30Q2 was about 3.4 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. EAA Guidance Document Revision: April 2014 Page 7 of 8 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 homes and bath house. 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 8 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 1.2%.

Box 7148 Ashville, NC 28802 May 6,2021 RE: Local Government Review Form Application for Discharge System — Broch Property Lower Beaverdam Loop Road, Candler, NC 28715 (PIN 9605-25-0161) Dear Ms. Campbell, Enclosed please find a Local Government Review Form required for a Certificate of Coverage application supporting a proposed wastewater treatment system (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 tiny home village located in Buncombe County, North Carolina (nearby the City of Asheville). 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 by licensed soil scientist. Please complete the enclosed form for inclusion in the application for the proposed system. This residence is located in Buncombe County.

The proposed system will be an individual discharge permit that is permitted under the NPDES Permitting Program. The proposed system will serve a proposed tiny home village located in Buncombe County, North Carolina. 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 by licensed soil scientist. Please complete the enclosed form for inclusion in the application for the proposed system. This 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.
