The proposed discharge system will serve an existing a 3-Bedroom Single Family Residence (SFR) located in Durham County, North Carolina. The proposed system will replace the unpermitted system that serves the residence. The site has been deemed unsuitable for ground absorption sewage treatment systems by the Durham County Environmental Health Department due to unsuitable soil topography and/or landscape position, unsuitable soil characteristics, unsuitable wetness conditions, and inadequate depth of soil. The proposed system is to be sized for 3 bedrooms at 360 gallons/day. This application is being submitted with the intent to have coverage under the NCG55 General Permit. Coverage under this permit is sought to replace an unpermitted sand filter system. The following information is included with this letter: Notice of Intent(NCG550000). Attachment A. $60 check payable to North Carolina DENR. Documentation from Durham County Health Department. Attachment B. Letter requesting coverage under the General Permit. Attachment C. Letter requesting Authorization to Construct. Attachment D. 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 Connecting to Regional Sewer. 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 existing surface drainage ditch on the southwest corner of the property that will flow south into an existing pond and east into a tributary to Cabin Branch. This discharge point is located on the subject property. The discharge system will utilize the following components: 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 existing surface drainage ditch on the southwest corner of the property. This roadside ditch flows south into an existing pond and then east into an unnamed tributary to Cabin Branch, the Blue Line Feature. This flow path serves is currently utilized by the existing, permitted discharge system on the adjacent property (230 Smith Dr—NCG551521). A map showing the path from the discharge point to the first "blue-line" stream, as shown on the Durham County GIS data, can be seen in Attachment G. Notice of Intent As part of the Notice of Intent, the feasibility of alternatives to discharging must be addressed. The following alternatives are to be evaluated: Connection to a regional or municipal sewer collection system. Letter from the local or county health department describing the suitability or non-suitability of the site for all types of wastewater ground adsorption and innovative non-discharge systems, as well as documenting the repair potential of the failed system. Investigate land application such as spray irrigation or drip irrigation. Connection to a Regional or Municipal Sewer Collection System Connection to a sewer collection system is not feasible for this facility. Ms. Laura Adcock, Engineering Services Supervisor of the Durham Public Works Department, indicated that the property is not within the city's coverage area. The closest current city maintained sewer is approximately 1,850 linear ft. from the property and there are no immediate plans for a sewer extension to the area at this time (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 be approximately$185,000. 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 Durham County Environmental Health Department indicated that the site is unsuitable for installation of a ground absorption septic system in letter dated August 1, 2017 (Attachment B). The letter indicated that a permit cannot be issued due to unsuitable soil topography and/or landscape position, unsuitable soil characteristics, unsuitable wetness conditions,and inadequate depth of soil. 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 sufficient space or suitable soil characteristics 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 existing drainage ditch that leads to an existing pond and tributary to Cabin Branch. The analysis from USGS indicates the 7Q10 discharge for the point in question is likely zero(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) - Unsuitable soil and insufficient space 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 Durham County and the City of Durham. A copy of the submittal is included as Attachment J. To date, the completed forms have not been received. • I appreciate your time and efforts in reviewing this application.

According to your application the site is to serve a 4 bedroom residence with a design wastewater flow of 480 gallons per day. The evaluation was done in accordance with the laws and rules governing wastewater systems in North Carolina General Statute 130A-333 including 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, Rule .1940 through .1948, the evaluation indicated that the site is UNSUITABLE for a sanitary system of sewage treatment and disposal. Therefore, we must deny your request for an improvement permit. A copy of the site evaluation is enclosed. The site is unsuitable based on the following: Unsuitable soil topography and/or landscape position (Rule .1940) riUnsuitable soil characteristics (structure or clay mineralogy)(Rule .1941) ©Unsuitable soil wetness condition (Rule .1942) IPIUnsuitable soil depth(Rule .1943) III"resence of restrictive horizon (Rule .1944) IIIInsufficient space for septic system and repair area (Rule .1945) III1Unsuitable for meeting required setbacks(Rule .1950) III•ther(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 Health Department 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).

" April 23, 2020 MEMORANDUM TO: Mr.Andres Rivera FROM: Chris McGee,LSS SUBJECT: Soils Evaluation for 226 Smith Drive Durham,NC (Durham County) Agri-Waste Technology, Inc. (AWT) was contracted to perform a soils evaluation for the purposes of on-site wastewater system suitability at the subject property in Durham, NC. The evaluation was performed by Alex Thompson and supervised by Chris McGee of AWT on April 23, 2020. A single-family residence with an unpermitted wastewater system is located at 226 Smith Drive. The property has been deemed unsuitable for subsurface wastewater systems by the Durham County Environmental Health Department. The soils on the subject property are unsuitable for subsurface and surface application wastewater systems due to shallow wetness conditions, shallow depth to expansive clay mineralogy, and insufficient 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. Ii Attachment 1. Correspondence from USGS 2.

FOR THE RECORD: Information provided as part of this request indicates the point of interest to be a ditch (ephemeral channel) upstream from a small pond feature (not visible on USGS 7.5-min quad map) located adjacent to the eastern end of Lin Tilley Road, south of Smith Drive, and north of Barclay Road. Existence of the pond feature was confirmed with visual examination of aerial images available via online sources. 1 of 4 5/19/2020,8:38 AM USGS response to DWR USGS Low Flows request#2020-60(dated... No USGS discharge records are likewise known to exist for the point of interest. In the absence of site-specific discharge records sufficient for a low-flow analysis, estimates of low-flow characteristics at ungaged locations are determined by assessing a range in the low-flow yields (expressed as flow per square mile drainage area,or cfsm) at nearby sites where estimates have been determined. A basin delineation completed using the online USGS StreamStats application for North Carolina (https://streamstats.usgs.gov/ss/) indicates the drainage area for the point of interest(StreamStats adjusted coordinates 36.10030, -78.90336 NAD83) is just slightly less than 0.01 sqmi. For streams in north central Durham County, low-flow characteristics published by the USGS are provided in the following reports: (1)The first is a basin-wide report for the Neuse River basin published in 1998. It is USGS Water-Resources Investigations Report 98-4135, "Low-flow characteristics and discharge profiles for selected streams in the Neuse River basin, North Carolina" (Weaver, 1998). The report is available online at http://pubs.usgs.gov /wri/1998/4135/report.pdf. This report provides low-flow characteristics(based on data through 1996)for USGS continuous-and partial-record sites in the Neuse River basin where sufficient data was available for analyses. However,the report does not provide statistical relations for estimating low-flow characteristics at ungaged locations. (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/2015f 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: Visual inspection of the stream location on a topographical map suggests an extremely small basin area upstream from the point of interest. As noted above,the drainage-area for the basin upstream from the point of interest is just slightly less than 0.01 sqmi. On pages 33-34 of the Neuse basin-wide low-flow report (first reference above) is information about the Occurrence of Zero or Minimal 7Q10 Discharge that is likely to occur for a stream within the major basin, contingent on the size of the upstream drainage basin. The discussion on page 33 in this section indicates that poorly drained soils(that is, soils having low infiltration rates) is a primary factor in numerous occurrences of zero 7Q10 discharges in the upper end of the study area [Neuse River basin]: "Much of the water that comes in contact with the soils in this area most likely enters the streams as overland runoff and does not infiltrate into surficial aquifers for later release during drought conditions. Among sites having zero 7Q10 discharges, the drainage areas range from less than 0.01 mi2 (site 10)to about 44 mi2 (site 121). For sites in this area having non-zero 7Q10 discharges, the average 7Q10 unit low flow is about 0.005 (ft3/s)/mi2. Therefore, sites with drainage areas less than about 10 mi2 could be expected to have zero or minimal 7Q10 discharges (less than 0.05 ft3/s)." Additionally,the basin upstream from the point of interest is underlain by the Triassic basin geologic unit. 2 of 4 5/19/2020,8:38 AM USGS response to DWR USGS Low Flows request#2020-60(dated... From a hydrologic perspective, streams underlain by this geologic unit have very little to no potentials for sustained base flows during extended dry periods. At sites underlain by the Triassic basin where the USGS has collected sufficient records for low-flow analyses,the low-flow characteristics for sites having drainageareas that would typically be expected to have sustained flows actually have some of the lowest low-flow estimates in the state. Consideration of the above information results in a conclusion the 7Q10 discharge for the point of interest is zero flow. Please understand the information provided in this message is based on a preliminary assessment and considered provisional, subject to revision pending further analyses. This low-flow response is provided via the DWR USGS Low Flows cooperative agreement between the USGS and the N.C. Department of Environmental Quality, Division of Water Resources. Hope this information is helpful. Thank you.

Salem Street, Suite 203 Apex,NC 27502 Office: 919-859-0669 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 existing drainage ditch in the southwest corner of the property. Effluent leads south in the ditch to an existing pond and empties to the east into a tributary to Cabin Branch. The analysis from USGS indicates the 7Q10 discharge for the point in question is likely zero (Attachment F of application package). Because this is an existing treatment system with zero flow,the discharge will be considered on a case-by-case basis. 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 3-Bedroom Single Family Residence(SFR) located in Durham County,North Carolina. The proposed system will replace an unpermitted system that currently serves the residence. The proposed discharge point is in an existing drainage ditch located on the southwest corner of the property, which leads to a tributary to Cabin Branch. 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. EAA Guidance Document Revision:April 2014 Page 1 of 8 Applicant Information: Name: Tamar Beridze Mailing Address: 218 Finley Forest Rd Chapel Hill,NC 27517 Phone Number: 919-717-4605 Contact Person: Andres Rivera Facility Information: Name: Beridze Property Address: 226 Smith Drive Durham,NC 27712 County: Durham Phone Number: 919-323-6588 Contact Person: Geoff Brantley EAA Preparer's Information: Name: Scott Jones,P.E. Mailing Address: Agri-Waste Technology,Inc. 501 N.Salem Street Apex,NC 27502 Phone Number: 919-859-0669 Contact Person: Scott Jones,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 3 bedrooms. For the 20-year planning period, the system will be designed for a 3-bedroom residence with a flow of 360 gallons per day. At 2 people per bedroom,the system will be designed to serve 6 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.Laura Adcock,Engineering Services Supervisor of the Durham Public Works Department, indicated that the property is not within the city's coverage area. The closest current city maintained sewer is approximately 1,850 linear ft. from the property and there are EAA Guidance Document Revision:April 2014 Page 2 of 8 no immediate plans for a sewer extension to the area at this time(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 be approximately $185,000. 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 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 City of Durham's sewerage system currently exists within five miles of the property,but a connection to this system is infeasible due to the cost. According to the Durham Public Works Department,there are no known plans to bring the city 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 Durham CountyEnvironmental Health Department indicated that the site is unsuitable for installation of a P P ground absorption septic system in a letter dated February 13,2020(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 can not 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 Mayodan series soil. For a subsurface system in this soil,a drip system with pretreatment would be required. This Mayodan soil is a sandy 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 3 of 8 Subsurface Dripfield Design Alternative #Bedrooms 3 Daily Flow 360 gpd = 120 gpd*#bedrooms LTAR 0.1 gpd/sqft Minimum Area Required (Nominal) 3,600 sqft =Daily Flow/LTAR Estimation for Topographical Variation 1,200 sqft Estimated Area Required (Actual) 4,800 sqft Approximate Area Available 5,076 sqft The current property's land available for the system is 5,076 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 4800 sq. ft., so there may be 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 Mayodan 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 3 Daily Flow 360 gpd = 120 gpd*#bedrooms Surface Loading Rate 19.5 in/year Minimum Area Required (Nominal) 10,810 sqft Approximate Area Available 3,530 sqft The current property's land available for a surface drip or spray system is 3,530 sqft, 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 and the value of the land as listed by the Durham County GIS website. The surrounding lots contain single-family residences. The values listed in the table do not reflect the value of the single-family residences. The soil types listed for these properties is Mayodan. These sites will be very restrictive for wastewater systems.

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(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 360 gpd Available Area to Irrigate 5,650 sgft *Veg. cover on property Application Rate 0.5 in/week Fescue Grass Acceptable Volume to Irrigate 235 ft3/week_ = 252 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. EAA Guidance Document Revision:April 2014 Page 5 of 8 Response: A Present Value Cost Analysis is included as Appendix B of the EAA. An analysis was performed for a P Y PP Y sub-surface drip system, a non-discharge surface application system, and a reclaimed water system. A summary of the analysis is included in STEP 4. 6. Provide all calculations, documentation and maps as necessary to support assumptions and conclusions. Response: Calculations performed to evaluate land application alternatives are shown above in Alternative B,Points 1 and 4. 7. Note:The design of land application systems must meet the treatment and design requirements specified in 15A NCAC 2T.0500 or 15A NCAC 18A.1900. Response: The treatment systems specified above in Step B would meet the treatment standards required by these rules as they pertain to single family residences. However, 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: Because this is an existing treatment facility with estimated zero flow at the discharge point and no expansion in discharge proposed,the discharge will be considered on a case-by-case basis. 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 under the general permit, as the general permit requirements (monthly average) are BOD5 = 30 mg/I 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/I and NH3-N of 1 mg/I can be met. While weekly sampling of the treated effluent would confirm the EAA Guidance Document Revision:April 2014 Page 6 of 8 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. 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. If excessive amounts of wastewater are generated,the wastewater will back up in the house. 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%.

Septic Tank A new 1,250-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 exits the AX-RT unit via gravity 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" 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. 1 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 bums 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 an existing drainage ditch located on the southwest property corner. 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: 11-May-20 PROJECT: Beridze Property Location: 226 Smith Drive Durham,NC 27712 County: Durham County SEPTIC TANK SIZING Daily Flow Estimate Flow/Unit #of Units 'Units I(gpd/unit) (Flow/Day(gpd) 3 BR 120 360 TOTAL DAILY FLOW(Q)= 360 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 428 gpd 60%of Daily Flow 216 gpd Total(apprx 1 day retention) 644 gal TANK SIZE PROVIDED= 1,250 gal.

It is important that the riser be sized correctly and installed properly(i.e.,appropriate tank adapter,attachment method,etc.)to ensure a watertight seal.Without a watertight seal,groundwater or surface water can leak into the tank,reducing the tank's perfor- mance.When setting a riser,orient the grommets in the appropriate directions before bonding to the tank. In this document,metric equivalents are omitted for nominal dimensions,such as riser and pipe diameters.If you are using pipe other than IPS standard sizes,consult your Distributor for adapters you may need. Riser Sizing The installed riser should extend about 3 in.(76 mm)above the finished ground level(approximately 2 in.[51 mm]for tank settlement and 1 in.[25 mm]to ensure drainage away from the riser).If the riser is too long,it may be cut to the appropri- ate height using a circular saw or table saw.Always cut excess length from the bottom of the riser.To ensure a good fit and watertight joint,a square cut is essential. If the riser is too short,a grade ring may be used as an extension. Selecting a Riser and Tank Adapter Installation Method To select an appropriate riser and tank adapter installation method,first determine the type of tank being used:concrete or fiberglass.Then refer to the chart below,as you follow these steps: Concrete Tanks 1. Determine desired riser diameter. 2. Determine if the riser tank adapter will be cast-in or bolted down. 3.

Handling strength is or MIN I �„ achieved within 12 hours,and full cure in 2 to 3 days.It comes in a r/ I 10.2-oz(300-mL)cartridge tube for application with a caulking gun. ADH1011PS810)adhesive is a white,two-component,self-leveling _`4 methacrylate adhesive for bonding PVC,ABS,fiberglass,and concrete. (. ADH10 comes in pint(500-mL)and quart(1000-mL)kits,consisting of A and B components(adhesive and activator),and requires hand mix- ing. If a self-leveling adhesive is NOT required or if concrete is NOT being bonded,SS115 or SS140 is preferred over ADH10. ADH845 adhesive is a tan two-component methacrylate adhesive for Clockwise from left.ADH10(IPS810)quart,SS115, bonding PVC,ABS,fiberglass,and concrete.This is our only adhesive ADH100,SS140,ADH845,ADH10(IPS810)pint and MA320 formulated to work in wet conditions or even under water,making it MA ideal for field repairs. Repairs on leaking riser connections are pos- sible,but any water pressure must be removed during the repair. ADH845 has the consistency of molasses,comes in 400-mL cartridges, and requires the manual dispensing gun ADH845-GUN. MA320 is a white two-component methacrylate adhesive that bonds PVC,ABS and fiberglass to themselves or each other,but does not bond to concrete.It comes in a two-part 200-gram see-through plastic pouch that must be kneaded to mix the two components,then cut open and squeezed to apply adhesive. SS140 adhesive is a gray two-component methacrylate adhesive for bonding PVC and fiberglass to themselves or each other. It does not bond to concrete. It has the consistency of toothpaste and will sag slightly in warmer temperatures.Surface roughening is recommended and provides the best bond strengths,but is not always necessary.Use SS140 above 65°F(18°C)and SS115 below 50°F(10°C).Working life of mixed adhesive is typically 20 to 30 minutes,and it usually hardens in less than 2 hours,depending on temperature and adhesive thick- ness. It comes in an 870-mL two-part cartridge and can be dispensed from pneumatic gun SS-MK or,for occasional use,manual gun SS-MK- MANUAL GUN. SS115 adhesive is a white two-component methacrylate adhesive with properties similar to those of SS140 and comes in the same two-part cartridge,but has a much shorter open time for use in cooler tempera- tures and jobs where quicker cure times are desired,or for applica- tions where a white color is desired.Working life of mixed adhesive is typically 10 to 15 minutes,and it usually hardens in less than 45 min- utes,depending on temperature and adhesive thickness.

Hint: If you plan to backfill the same day,the use of MA320,SS115 or SS140 adhesive is recommended because of their quicker cure times. Cast-in PRTA30 tank adapter If you have multiple riser installations and do not have bulk adhesive (SS115/SS140),consider using both MA320 and ADH100.Apply just °' enough MA320 on the outside of the tank adapter for a quick structural ®'` y joint(cure time is typically less than an hour).A single package of 44 MA320 can be used to provide a structural joint on two or three risers. Then apply ADH100 to the inside of the adapter and the riser joint,for a watertight seal. Step 2b: Place Riser 116 Orient the riser correctly and carefully slide it onto the adapter before the adhesive cures. Step 2c: Seal Adapter-to-Riser Joint Apply adhesive to the inside of the adapter and riser joint. Use a putty knife or similar tool to form a continuous fillet between the tank adapter and the inside of the riser. 1,, . Step 2d: Cure Adhesive IP Allow adhesive to harden before backfilling.For ADH100,handling strength is typically achieved within 12 hours.For MA320,cure time is achieved within 30 minutes to 3 hours,depending on temperature. mow,. ebe NIN-RLA-RR27 ®2006 Orenco Systems Inc.

Septic Tanks Used in AX-RT'f a �g, ux 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. AKey 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.If sufficient fall cannot be met,a grade ring extension must be installed on the AX-RT or a pumping system will need to be installed in the septic tank to move the filtered effluent to the AX-RT unit.

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.

NIN-MF-MF-1 Rev.20,011p4 Page 3of4 Maintenance Instructions Manes 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.
