The proposed system will replace a failing sub-surface system that currently serves the residence. The site has been deemed unsuitable for ground absorption sewage treatment systems by the North Carolina Department of Health and Human Services due to unsuitable soil conditions and insufficient space. The proposed system is to be sized for 4 bedrooms (480 gallons per day) and has been designed to convey all wastewater from the SFR, including greywater. This application is being submitted with the intent to have coverage under the NCG55 General Permit. Coverage under this permit is sought to replace a failed sub-surface system. The following information is included with this letter: - Notice of Intent (NCG550000). Attachment A. - $60 check payable to North Carolina DEQ. - Documentation from Watuaga County Health Department. Attachment B. - Letter requesting coverage under the General Permit. Attachment C. - Letter requesting Authorization to Construct. AttachmentD. - Soils Evaluation report by Chris McGee of AWT, Inc. Attachment E. Correspondence from USGS. Attachment F. - Flow Path to "Blue Line" Water Feature.Attachment G. Information on Connection to a Regional Sewer System.Attachment H. Engineering Alternatives Analysis (EAA).Attachment I. Local Government Review Forms. Attachment J. Plans and Specifications for the proposed system. Attachment K. The discharge point is in an un-named tributary of Gap Creek, located to the north of the applicant's property. The discharge system will utilize the following components: - New Septic Tank with Effluent Filter AdvanTex AX-20 RT Pod - Re-circulation Pump Chamber(Integrated into AdvanTex Pod System) - UV Disinfection Discharge Point with Rip-Rap Flow Path to "Blue Line"Water Feature The proposed discharge location is in an un-named tributary of Gap Creek, the Blue Line feature. A map showing the path from the discharge point to the first "blue-line" stream, as shown on the Watauga County GIS data, can be seen in Attachment G. The discharge point is located on the subject parcel. Notice of Intent As part of the Notice of Intent, the feasibility of alternatives to discharging have been addressed. The following alternatives have been 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. Connection to a Regional or Municipal Sewer Collection System Connection to a sewer collection system is not feasible for this facility. Ms. Amy Phillips of the Watauga County Planning & Inspections Department indicated that sewer is not currently available for the applicant's property. The closest sewer system is located at a Food Lion grocery store approximately 5.8 miles from the applicant's property (Attachment H). 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 Regional Soil Scientist with the North Carolina Department of Health and Human Services indicated that the site is unsuitable for installation of a ground absorption septic system in letter dated October 25, 2018. (Attachment B). The letter indicated that a repair permit cannot be issued due to unsuitable soil wetness conditions, unsuitable soil depth, and insufficient space. Investigate Land Application such as spray irrigation or drip irrigation. Per the soil evaluation by Chris McGee of Agri-Waste Technology, Inc. the site does not have suitable soil characteristics or adequate space to accommodate a non-discharge surface spray or drip wastewater system(Attachment E). 7Q10 Flow Estimate The United States Geological Survey (USGS) was contacted to determine the 7Q10 flow estimate for the proposed wastewater discharge point. The proposed discharge point is in an un-named tributary of Gap Creek. The analysis from USGS indicates the 7Q10 and 30Q2 flows are estimated to be positive values for the discharge point in question (Attachment F). Engineering Alternatives Analysis An Engineering Alternatives Analysis (EAA) has been completed for this site and is included as Attachment I. In my opinion, the completed EAA demonstrates that a wastewater treatment system permitted under the NCG550000 General Discharge Permit 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. b.) subsurface disposal - No suitable soil for a subsurface absorption system. c.) single-family residence wastewater irrigation (drip and spray) - No suitable soil for a non-discharge ground absorption system. d.) reclaimed-water systems - No suitable soil 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 Watauga County and the Town of Boone. A copy of the form submittals is included as Attachment J. To date, the completed forms have not been received. Plans and Specifications Plans and Specifications for the proposed system are included as Attachment K. I appreciate your time and efforts in reviewing this application. If you have any questions or comments,please feel free to contact me at 919-859-0669. Best Regards, Kevin Davidson,P.E.

Boone,NC 28607 Subject: Repair of subsurface treatment and disposal system for Ms. Angela Shoemake Owner: Angela Shoemake Location: 429 Dick Watson Rd,Deep Gap,NC ,28618 Parcel Number: 2951-63-0358-000 Size: 0.48 total acres Mr. Blethen: On October 23, 2018, I performed a soil and site evaluation of the aforementioned property. Also,present was yourself, Luke Price(REHS),Jared Nemeth(Doby's Plumbing)and the owner for part of the visit. This visit was made to attempt to do a failure analysis of the existing system and then, if needed, evaluate the site to determine the suitability for a repair of the subsurface treatment and disposal system serving the existing four-bedroom residence. A shared well system, located on the adjacent property(387 Dick Watson Rd.),provides the residence's water supply. The original subsurface system(location unknown)was repaired in 1997 (permit#95917R). The existing subsurface system has repeatedly failed by surfacing between the system area and the shed. According to the owner,the failure occurs more often after rain events. Evidence of this failure was present. However, a failure analysis to fix the failure or repair the existing system is not possible. This is because it appears that on or around August 4,2017,the previous owner attempted to fix the system without a permit. At a minimum,this attempt consisted of a gravel pit being dug above and possibly within the permitted system. This was partially located by probing on 10/23/18. According to documentation provided by the current owner,this attempt may have consisted of "a massive 4' wide by 30ft long by 8ft deep"pit. Other illegal modifications have also been done to the system. Another unpermitted gravel trench/pit was located,by probe, above the NC DEPARTMENT OF HEALTH AND HUMAN SERVICES• DIVISION OF PUBLIC HEALTH LOCATION:5605 SIX FORKS RD,RALEIGH NC 27609 MAILING ADDRESS:1642 MAIL SERVICE CENTER,RALEIGH NC 27699-1642 www.ncdhhs.gov • TEL:919-707-5874 • FAX:919-845-3972 AN EQUAL OPPORTUNITY/AFFIRMATIVE ACTION EMPLOYER outbuilding. An overflow pipe was added to the tank above the original outlet pipe. No sign of this pipe was seen in the creek bank,but the system has not been dyed. It is unknown where this overflow pipe goes. (An attempt was made earlier to run a camera down the line,but the camera was too big.) The concrete outlet tee has been removed. The tank is also drastically out of level and the existing deck encroaches on both the tank and drainfield. The property was evaluated in accordance with the North Carolina Laws and Rules for Sewage Treatment and Disposal Systems, 15A NCAC 18A .1900. Listed below are the results of the evaluation and recommendations for the site. Please share this report with the applicant/property owner. The most limiting site factors encountered are listed below: • Soil Wetness Condition (SWC) (Rule .1942)-is less than 12-inches below the natural soil surface (pit 3) and less than 15 and 13 inches (pits 1&2)based on soil colors of chroma 2 or less (Munsell Color Chart). • Soil Depth(Rule.1943)-less than 30(pits 1), 18 (pit 3)28 (pit 2) inches below the natural soil surface. • Available Space(Rule .1945)-insufficient space on the property with soils that can be classified as suitable or provisionally suitable(i.e.usable/modifiable soils) for the repair of the ground absorption sewage treatment and disposal system. Available space on this site was limited by: o a five(5) foot horizontal separation distance to any property line. o a fifty(50) foot horizontal separation distance to spring/creek. o a five(5) foot horizontal separation distance to any footer. o a ten(10)foot horizontal separation distance to any water line. o a driveway and other structures. Site Classification The site is NONREPAIRABLE and any modification would not reasonably enable a system to function properly,Rule 15A NCAC 18A .1961(1). This is due to the site being UNSUITABLE for installation of a subsurface treatment and disposal system as to depth to soil wetness (Rule 15A NCAC 18A .1942), lack of available space(Rule 15A NCAC 18A .1945) and unable to maintain setbacks (Rule 15A NCAC 18A .1950). Currently,the site is classified as UNSUITABLE per Rule .1948 based on the above referenced soil/site limitations. This site is unsuitable under Rule .1955, Conventional Sewage Systems. This site is unsuitable under Rule .1956,Modifications to Septic Tank Systems. This site is unsuitable under Rule .1957,Alternative Sewage Systems. This site is unsuitable under Rule .1969,Experimental, Innovative,Accepted Systems, Components,or Devices. Recommendations The owner and applicant have the following options that might allow the use of this property as desired: 2 1. The applicant may purchase other suitable or provisionally suitable property to place the ground absorption sewage treatment and disposal system. 2. The applicant may obtain an easement on a suitable or provisionally suitable property to place the ground absorption sewage treatment and disposal system. 3. The applicant/owner may apply for and receive a permit for permanent Pump and Haul from our Department under Rule .1961, to an approved NCDEQ facility. 4. The Division of Water Resources,NC Dept. Environment Quality(NCDEQ)in Raleigh, North Carolina may be contacted at(919) 791-4200 or your Winston-Salem Regional office at 336-776-9800 to pursue options available through that department. 5. A ground absorption sewage treatment and disposal system can be pursued under Rule 15A NCAC 18A .1948(d). Written documentation, including engineering,hydro- geologic, geologic or soil studies, shall indicate that the proposed system can be expected to function satisfactorily. The substantiating data shall indicate that: 1. A ground absorption system can be installed so that the effluent will be non- pathogenic,non-infectious,non-toxic, and non-hazardous; 2. The effluent will not contaminate groundwater or surface water; and 3. The effluent will not be exposed on the ground surface or be discharged to surface waters where it could come in contact with people, animals, or vectors.

SUBJECT: Soils Evaluation for 429 Dick Watson Road Deep Gap,NC (Watauga County) A soils evaluation was conducted for the property located at 429 Dick Watson Road, Deep Gap, NC (Watauga County). The evaluation was conducted by Chris McGee, LSS of AWT on April 2, 2019. A failing subsurface septic system currently serves the single-family residence located on the site. The septic system is located to the east of the residence. The site has been deemed unsuitable for a ground absorption sewage system by the North Carolina Department of Health and Human Services. The soils on the subject property are unsuitable for subsurface and surface application wastewater systems due to unsuitable soil wetness conditions, unsuitable soil conditions, and inadequate space. Therefore, the property does not comply with the requirements of 15A NCAC 18A Section .1900 — Sewage Treatment and Disposal Systems -or- 15A NCAC 02T Section .0600 — SFR Wastewater Irrigation Systems. The site is a likely candidate for a surface water discharge system. Please contact us with any questions, concerns, or comments. Attachment F 1. Correspondence from USGS 2. Stream Classification Kevin Davidson From: Weaver,John <jcweaver@usgs.gov> Sent: Tuesday, April 9, 2019 2:40 PM To: Julie Davidson Cc: Kevin D. Davidson; Kevin Chapman;John C Weaver Subject: Response from USGS concerning...Re: [EXTERNAL] 7Q10 flow request-Del Nero Ms. Davidson, In response to your inquiry about the low-flow characteristics(7Q10,30Q2,average annual discharge)for a location on an unnamed tributary to Gap Creek at Deep Gap in eastern Watauga County,the following information is provided: No USGS discharge records are known to exist for the point of interest,as identified by the lat/long coordinates(36.23370,-81.52246) provided in your email dated April 05,2019. 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,of cfsm)at nearby sites where such estimates have previously been determined. A basin delineation completed using the online USGS StreamStats application for North Carolina (http://water.usgs.gov/osw/streamstats/north carolina.html)indicates the drainage area for the point of interest(36.23370,- 81.52246 NAD83)is 0.06 sgmi. For streams in eastern Watauga 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 sgmi 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 analyses. Inspection of the above reports indicates the presence of ten(10)selected nearby USGS partial-record sites(8)and continuous-record streamgages(2)in vicinity of the point of interest where low-flow characteristics were published. Among these 10 sites,the low-flow discharge yields for the indicated flow statistics are as follows: Annual 7Q10 low-flow yields==>from 0.26 to 0.56 cfsm(average about 0.4 cfsm,median about 0.42 cfsm) Annual 30Q2 low-flow yields==>from 0.63 to 0.94 cfsm(average about 0.78 cfsm,median about 0.8 cfsm) Average annual discharge yields==>from 1.6 to 3.2 cfsm(average about 2.0 cfsm,median about 1.9 cfsm) Application of the above range in yields to the drainage area(0.06 sqmi)for the point of interest results in the following estimated low-flow discharges: Annual 7010 discharges==>from about 0.02 to 0.03 cfs(average about 0.02 cfs,median about 0.03 cfs) Annual 30Q2 discharges==>from about 0.04 to 0.06 cfs(both average and median about 0.05 cfs) Average annual discharge==>from about 0.1 to 0.19 cfs(average 0.12 cfs,median about 0.11 cfs) Please note the estimated flows are provided in units of cubic feet per second(cfs). 1 Please understand the information provided in this message is based on a preliminary assessment and considered provisional,subject to revision pending further analyses. Hope this information is helpful. Thank you.

Salem Street, Suite 203 Apex,NC 27502 Office: 919-859-0669 Direct: 919-747-2306 Engineering Alternatives Analysis (EAA) Guidance Document North Carolina Division of Water Resources STEP 1. Determine if the proposed discharge will be allowed 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 flow estimate for the downstream tributary of the proposed wastewater discharge point. The proposed discharge point is in an unnamed tributary of Gap Creek. The tributary is located on the eastern property boundary and runs north and then northeast before joining with Gap Creek. The analysis from USGS indicates the 7Q10 discharge for the point in question averages 0.02 cfs. The 30Q2 flow was also estimated at 0.05 cfs(Attachment F of application package). Because of the positive stream flow,the discharge should be allowed. 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 4-Bedroom Single Family Residence (SFR) located in Watauga County, North Carolina. The proposed system will replace a failed sub-surface system that currently serves the residence. The proposed discharge point is in an unnamed tributary located on the eastern property line. The tributary leads to Gap Creek. The proposed treatment system will utilize the following components: New Septic Tank with Effluent Filter - AdvanTex AX-20 RT Pod Recirculation Pump Chamber(Integrated into AdvanTex Pod System) - 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.

Mailing Address: Agri-Waste Technology,Inc. 501 N.Salem Street Apex,NC 27502 Phone Number: 919-859-0669 Contact Person: 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: Because the wastewater treatment system is designed for a single-family residence, the population to be served will be limited by the number of bedrooms at the individual residence. The existing house contains 4 bedrooms. For the 20-year planning period,the system will be designed for a 4-bedroom residence with a flow of 480 gallons per day. At 2 people per bedroom,the system will be designed to serve 8 residents. 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.Amy Phillips of the Watauga County Planning & Inspections Department indicated that sewer is not currently available for the applicant's property. EAA Guidance Document Revision:April 2014 Page 2 of 8 The closest sewer system is located at a Food Lion grocery store approximately 5.8 miles from the applicant's property(Attachment H). For reference,if an installation cost of$100/ft of installed sewer line was assumed,the cost to connect this property to the sewer line would exceed $2,500,000. Additional costs including the cost of any 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 homeowner. (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 stated above, the Town of Boone's sewerage system exceeds five miles of the property,but a connection to this system is infeasible due to the cost. According to the Planning and Inspection Department, there are no known plans to bring the sewer system closer to the applicant's property. 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 Regional Soil Scientist with the North Carolina Department of Health and Human Services indicated that the site is unsuitable for installation of a ground absorption septic system in letter dated October 25, 2018 (Attachment B of application package). The letter indicated that a repair permit cannot be issued due to unsuitable soil characteristics and insufficient space. Per the soil evaluation by Chris McGee of Agri-Waste Technology,Inc.the site does not have adequate space or suitable soil to accommodate a ground absorption or surface drip or surface spray wastewater system(Attachment E of application package). Regardless of the fact that a subsurface ground absorption system 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 Saunook-Nikwasi Complex. This soil is limited for septic fields if the Nikwasi soil is present. For a subsurface system at this site, a drip system with pretreatment would likely be required. This soil is typically a brown loam soil that would have a long-term acceptance rate (LTAR) ranging from 0.05-0.2 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 3of8 Subsurface Dripfield Design Alternative #Bedrooms 4 Daily Flow 480 gpd =120 gpd*#bedrooms LIAR 0.1 gpd/sqft Minimum Area Required (Nominal) 4,800 sqft =Daily Flow/LTAR Estimation for Topographical Variation 1,600 sqft Estimated Area Required (Actual) 6,400 sqft Approximate Area Available 433 sqft The current property's land available for the system is 433 sqft, due to setbacks and existing site conditions. This area also considers maintaining a 50' well setback. 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 6,400 sq. ft., so there is not sufficient space for this type of system at the residence. 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 Saunook-Nikwasi. 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 4 Daily Flow 480 gpd =120 gpd*#bedrooms Surface Loading Rate 26 in/year Minimum Area Required (Nominal) 10,810 sqft Approximate Area Available 35 sqft The current property's land available for a surface drip or spray system is 35 sq ft,due to setbacks and existing site conditions. A schematic of this area is shown in Appendix A. The land needed for a non-discharge application system is estimated at 10,810 sq. ft., so there is insufficient space at this residence. The potential waving of property setbacks was taken into account when considering the available application area for both surface systems. 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, offsite land was reviewed. The table below lists neighboring properties (that could potentially be used) and the value of the land as listed by the Watauga County GIS website. It is my understanding that the possibility of an easement was discussed with this landowner. However,no agreement could be reached. Adjoining Property Values Neighboring Property Area (ac) Vacant Price of Land ($) ParlD 2951633451000 (East) 13.75 N 455,370 EAA Guidance Document Revision:April 2014 Page 4 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: onents: -Septic Tank with Effluent Filter -Recirculation Tank(Integrated in AX20-RT unit) -AdvanTex Treatment Pod(AX20-RT unit) -Pump Tank(potentially integrated in AX20-RT unit) -UV Disinfection(Integrated in AX20-RT unit) -Headworks Box -Control Panel -Disposal Field(drip or spray) 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 size requirements of a drip or spray system and the limited available space,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. The existing residential plumbing infrastructure does not allow for reuse in the existing residence. 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,there is insufficient area to utilize the daily flow of reclaimed water. On-site Utilization of Reclaimed Water Daily flow through system 480 gpd Available Area to Irrigate 3,614 sqft *Veg cover on property Application Rate 0.5 in/week *Fescue Grass Acceptable Volume to Irrigate 151 ft3/week = 161 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. 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. EAA Guidance Document Revision:April 2014 Page 5 of 8 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, because of the lack of available space and other 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: The analysis from USGS indicates the 7Q10 discharge for the point in question averages 0.02 cfs. The 30Q2 flow was also estimated at 0.05 cfs (Attachment F of application package). Because of the positive stream flow, the discharge should be allowed. 2. All direct discharge systems of oxygen-consuming wastes should be evaluated both with tertiary filtration [BOD5= 5 mg/1, NH3-N= 1 mg/11 and without, and assuming a weekly sampling regime. Response: Tertiary filtration is not required under the general permit, as the general permit requirements (monthly average) are BOD5 = 30 mg/1 and Total Suspended Solids = 30 mg/1. However, 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. While weekly sampling of the treated effluent would confirm the treatment results on a regular basis, the additional cost associated with the collection and testing of the effluent would not be feasible for the homeowner. 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: Plans and schematic drawings can be found in Attachment K(of application package). 4. Provide documentation of the availability of required land and/or easement agreements. EAA Guidance Document Revision:April 2014 Page 6 of 8 Response: The proposed discharge system will be located on land owned by the applicant. See Attachment K (of application package)for the proposed discharge system location. 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 a well and does not have elevated water storage tanks. In the event of a power outage,water will not be available to the residence. There is storage available in the system to hold some waste from the house 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 7 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"Present Value of Costs"is based on a discount factor of 1.2%.

The proposed system will be permitted under the NCG550000 General Discharge Permit for Single Family Residences and other 100% Domestic Waste Discharges. The proposed system will serve an existing 4-bedroom home located in Watauga County, North Carolina. The residence is currently served by a failing, un-permittable sub-surface wastewater (septic) system. A new recirculating media filter-based system will be installed to serve the residence. The proposed system will allow the residence to become compliant with current NC DEQ standards. A general location map as well as information on the proposed system are enclosed for your review. The Regional Soil Scientist with the North Carolina Department of Health and Human Services indicated that the site is unsuitable for installation of a ground absorption septic system. It is my opinion that a wastewater treatment system covered by the General Discharge Permit is the only technologically and economically feasible option for this residence. Will you please complete (sign and notarize) the enclosed form for inclusion in the application for the proposed system. This residence is located in Watauga County and is located outside any city limits. 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 919-367-6310. Best Regards, Kevin Davidson, P.E. V.P. of Engineering Del Nero Property 429 Dick Watson Road Deep Gap, NC 28618 Attachment A.

Septic Tank A new 1,500-gallon septic tank will be installed for this system. The septic tank will include an effluent filter and risers. An Orenco 8" Biotube effluent filter will be installed in the outlet end of the septic tank. New access risers will be installed on both the inlet and outlet ends of the septic tank. To facilitate the installation of the access risers, riser adapters will be cast into the tank top during construction. All wastewater from the single-family residence,including greywater,will be routed into the septic tank. Waste that exits the septic tank will flow into the AdvanTex AX20-RT Treatment Pod. AdvanTex AX20-RT Treatment Pod The treatment component of the system is an AdvanTex AX20-RT treatment pod. The pod is an integrated unit that combines recirculation, treatment, and discharge modules into a single, sealed unit. Liquid from the septic tank will flow via gravity to the inlet of the treatment pod and into the recirculation tank portion of the AX-RT unit. Liquid from the recirculation tank will be periodically applied across the filter fabric. Wastewater will be sprayed over the textile sheets. The wastewater percolates down through the textile sheets and is distributed between the recirculation chamber and discharge chamber by means of the tank baffle. The treated wastewater will be pumped from the AX-RT unit to the discharge outlet. Prior to exiting the AX-RT unit,effluent passes through the UV disinfection system. The recirculation pump is controlled by a system of 3 floats that operate the recirculation pump in a Timed Dose arrangement. Float 1 (lowest elevation) is a redundant off float. Float 2 is a Peak Enable Float and Float 3 acts as a High Water Alarm. Under normal operation the redundant off float will be engaged thereby activating the timer in the control panel. At the pre-set interval, the pump will engage and distribute effluent over the textile fabric("on"cycle). Following this period, the pump will turn off and rest for a designated time("off"cycle)". During periods of high water in the recirculation portion of the tank,the Peak Enable float will engage and reduce the pre-set"off" 1 time and thereby send increased flow across the fabric. If the water level in the recirculation tank continues to rise for a pre-set time period,the High-Water Alarm will activate. To prevent groundwater from affecting the pod,the pod will be installed on a bed of gravel. Anti- flotation measures or a concrete ring installed around the mid-flange will be installed to provide extra ballast to prevent the flotation of the pod during high water table conditions. UV Disinfection Disinfection for the system will be accomplished using a UV system. The UV light should operate for approximately one year prior to needing to be replaced. If the UV light burns out or loses sufficient intensity(below a set threshold)an alarm will activate and disable the system pump. An alarm light on the control panel will also illuminate. When the alarm is activated,the homeowner should reduce water use(laundry, dishes,washing)until the system is operating properly. Discharge Outlet The system discharges into a roadside ditch located off of the northern property line. Riprap will be placed at the discharge location to provide aeration of the water as it is discharged and also as erosion protection. Vegetation and debris should be kept clear of the discharge location. A grate will be installed on the discharge pipe to prevent animals and rodents from entering the discharge pipe. Control Panel One control panel will be installed with this wastewater system. This panel will control operation of the re-circulation pump and UV system. If desired, this panel can be connected to a land-based phone line that will notify the operator of system operation. 2 Discharge Wastewater Treatment System Design Calculations Date: 22-Apr-19 PROJECT: Del Nero Residence Location: 429 Dick Watson Road Deep Gap,NC 28618 County: Watauga County SEPTIC TANK SIZING Daily Flow Estimate Flow/Unit #of Units 'Units (gpd/unit) Flow/Day(gpd) 4 BR 120 480 TOTAL DAILY FLOW(Q)= 480 gpd Septic Tank Volume/Size(based on denitrification process) For Single Family Residences with 5 bedrooms or less, #Bedrooms I Min.Volume(gal) 2 1000 3 1250 4 1500 5 1750 Approximate Return Flow from Pod 720 gpd 60%of Daily Flow 288 gpd Total(apprx 1 day retention) 1,008 gal TANK SIZE PROVIDED= 1,500 gal.

Septic Tanks Used in AX-RT Treatment Systems Be sure that any septic tank used in an AX-RT Treatment System meets the following conditions: •The tank must conform to an approved and authorized tank design for AdvanTex Systems,and it must meet all applicable regula- tory requirements(no pour-in-place tanks, no homemade tanks,etc.). Call your local Dealer for specifics. •The tank must be structurally sound, •The tank must have at least 1000 gal.(3800 L) capacity for an AX20-RT, 1250 gal. (4730 L)for a 5-bedroom AX25-RT,and 1500 gal.(5680 L)for a 6-bedroom AX25-RT at the normal operating level (below the invert of the outlet). •The tank must have an at-grade access with a watertight,securable and removable lid. If it doesn't, an at-grade access must be installed onto the septic tank and be made watertight. •The tank must be watertight and free of leaks. •An Orenco effluent filter(model FTS0444-36V, FTW0444-36V,or FT0822-14B) must be installed in the septic tank. AiiKey Point:For existing septic tanks—the tank's depth of burial must allow for a minimum fall of 1/8 inch per foot(10 mm per meter or 1%)from the septic tank's invert of outlet to the AX-RT unit's invert of the inlet.

Effluent from the clear zone passes through a Biotube®Effluent Filter and is discharged to the recirc/blend chamber of the AX-RT unit,The effluent flows through the recirc transfer line to the recirc pumping system,which pumps filtered effluent to the distribution manifold in the top of the unit.Effluent percolates down through the textile media and is divided—by means of a tank baffle —between the recirc/blend chamber and the recirc/filtrate chamber inside of the unit. The recirc pumping system's operation is controlled by a timer in the control panel. It allows the pump to dose the textile media for short periods(usually 40-60 seconds),typically 72 times a day.These frequent"micro-doses,"which optimize the treatment process, occur throughout the day to maintain the proper biological environment.

In these cases, uses 3/4-in. (s 19 mm) rounded gravel,crushed stone,or pea gravel as fill material.This material should be washed,free-flowing, and free of debris. • For installations in non-cohesive soils*with high seasonal water tables, use 3/4-inch crushed rock as the backfill material. • Do not backfill with sand. Step 16c: Compact the fill thoroughly with a mechanical compactor. Key Points: •The bottom of the AX-RT lid should sit 2 inches(50 mm)above final grade. •After backfilling, call the system's Service Provider to arrange for the official System Start-up. Step 16d: Be sure the AX-RT unit's lid is closed and secured. Step 16e: Be sure the septic tank's access lids are secured. *As described in OSHA Standards(29 CFR,Part 1926,Subpart P,Appendix A),noncohesive soils or granular soils include gravel,sand,or silt with little or no clay content.Granular soil cannot be molded when moist and crumbles easily when dry.Cohesive soils include clayey silt,sandy clay, silty clay,clay,and organic clay.Cohesive soil does not crumble,can be excavated with vertical sideslopes,is hard to break up when dry,and when moist,can be rolled into threads without crumbling.For example,if at least a 2-inch(51-mm)length of 1/8-inch(3-mm)thread can be held on one end without tearing,the soil is cohesive.

The assembly is detachable without removal of the screened pump vault or effluent screen.A typical float switch assembly is shown below. Step 1: Each float cable is provided with a color marker.This marker indicates the O I function of the float. Make sure that your float cable color markers corre- spond with the wiring diagram provided. If the wiring diagram does not Float function match your float cable marker colors, contact Orenco Systems® Inc.or color marker Float stem your local dealer for assistance.

Note: See the splice box instructions(EIN-SB-SB-11 and corresponding splice box diagram for connection instructions. 2003 Orenco Systeme Inc. NIN-MF-MF-1 Rev.2.0,©11/04 Page 3 of 4 ! f Maintenance Instructions Orenco Systems' Incorporated 1-800-348-9843 During the annual inspection,follow the testing procedures provided to ensure that the system is operating properly. If a float is found to be faulty,either during the annual inspection or during troubleshooting after an alarm condition,see the section below titled Removing and Replacing Inoperative Floats. Removing and Replacing Inoperative Floats Important Before doing any work either on the wiring to the level control floats and pump in the vault or in the pump control panel,switch the circuit breakers in the panel to their"OFF"positions;then switch off the power to the system at the service entrance panel. 1. Remove the float assembly from the vault. 2. Using a Phillips screwdriver,remove the stainless steel screws from the splice box lid,being careful not to drop the screws into the tank. If the splice box was submerged,or if there is a crack in the conduit,there may be water in the splice box. If this is the case,remove water from the splice box with a syringe,sponge,or other appropriate method.Loosen the cord grip at the splice box and verify the appropriate splice for the float. Unscrew the wire nuts and remove the float. 3. Remove the inoperative float and replace it with a new one. Push the float cable through the watertight cord grip into the electrical splice box. Leave an adequate length of electrical cord coiled inside the riser to allow for easy removal of the float assembly. Do not remove the colored markers or the paper tags from the float cords,and do not try to thread the markers and tag through the cord grip.Tighten the cord grip by hand,not by tool,then test the tightness of the cord grip by tugging on the cord.A cord is secure when the cord grip is tight enough to prevent slippage.An adequate length of cord should be left within the splice box to allow for easy removal for future disconnecting and resplicing. 4. Refer to document EIN-SB-SB-1 for instructions to splice the float wire to the wire from the control panel.Attach the float wires using the waterproof wire nuts. It is necessary to replace this wire nut with a new watertight wire nut.Always use watertight wire nuts or heat shrink splice kits for all connections! 5. Replace the float and collar and return the assembly to the pump vault. 6. Reconnect power and test the unit. NIN-MF-MF-1 ©2003 Orenco Systems°Inc. Rev.2.0,©11/04 Page 4 of 4
