RE: Application for Discharge System—Del Nero Residence
429 Dick Watson Road, Deep Gap,NC 28618
Dear Mr. Hennessy,
Enclosed please find information supporting an application for a discharge system for a 4-
Bedroom Single-Family Residence (SFR) located in Watauga County, North Carolina. 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.

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

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.

RE: Letter Requesting Coverage under the General Permit—Del Nero Property.
429 Dick Watson Road, Deep Gap, NC 28618.
Dear Mr. Hennessy;
Please consider this letter as a request for coverage under the General Permit for a Multi-
Phase Filter System. The proposed discharge system is for a 4-Bedroom Single Family
Residence (SFR) located in Watauga County, North Carolina. The proposed discharge
system will replace the failing 4-bedroom system that currently serves the residence. The
site has been deemed unsuitable for ground absorption sewage treatment systems by the
NC Department of Health and Human Services due to inadequate soil conditions and
limited space. The proposed system is to be sized for 4 bedrooms at 480 gallons/day.
The residence is located at 429 Dick Watson Road, Deep Gap, NC 28618.
Thank you for your assistance in this matter.

MEMORANDUM
TO: Ms. Angla Del Nero
FROM: Chris McGee, L.S.S.
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.

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).

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.

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.

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.

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%.

A North Carolina homeowner had a conven- w. -, -` E.

He suggested the installation of an AdvanTex
AX20-RT unit with UV disinfection. This treatment combination was designed to meet
permit limits(<30 mg/L BODS and TSS; <200 cfu/mL fecal coliform)without requiring
a new drainfield.
Davidson was able to use the existing septic tank,and the RT's configuration further re-
duced costs by eliminating the need for a discharge tank, separate UV basin, and sev-
eral risers and lids. On the O&M side, he appreciated having the UV sensors integrated

RE: Local Government Review Form
Application for Discharge System—Del Nero Residence
429 Dick Watson Road,Deep Gap,NC 28618
Dear Mr. Davis,
Enclosed please find a Local Government Review Form required for a Certificate of
Coverage application supporting a proposed wastewater treatment system (system). The
proposed system will be 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.

Narrative Description
of
Discharge Treatment System
The Discharge System that has been designed considers the following components:
- Septic Tank
-AdvanTex AX20-RT Treatment Pod
-UV Disinfection
-Discharge Outlet
- Control Panel
Due to the advanced technology in this system, a Certified Operator should be contracted to
maintain this system.
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.

PVC Riser Installation
Installing PVC Access Risers onto Cast-In Orenco® Riser-Tank Adapters
Access risers provide access to septic tank openings,simplifying inspection and maintenance procedures.Access riser-to-tank connections
must be watertight for the proper functioning of an onsite septic system or effluent sewer system.Orenco strongly recommends watertightness
testing of all access riser-to-tank connections after installation.
Following are instruction sets for prepping and installing access risers, installing grommets,and selecting adhesives for riser installations.
Refer to the chart below to determine which instruction set to use.

Instruction Set 1:Riser Preparation
Step 1:Determine Riser Height 0
Determine riser height
Determine how high the riser needs to be.
• The top of the riser should be about 3 inches(75 mm)above finished grade 3 inches(75 mm)
after installation and backfilling—This allows 2 inches(50 mm)for tank �.
settling and 1 inch (25 mm)for ensuring drainage away from the riser.
2. . o ,
Step 2:Cut Riser to Size(if Necessary) ' . o
o 'c •
If the riser needs to be cut to size,cut it with a circular saw or table saw. c.•'o' 4 0
• Always cut excess length from the bottom of the riser. �•'• p , <
• For square,even cuts, a good fit, and a watertight joint between the riser • o . c
and the adapter, use an Orenco riser-cutting saw guide. o •
• To install risers less than 30 inches(760 mm) wide onto 500-gallon
(2000-L) Orenco FRP tanks,cut the riser so it fits into the tank and the
lowest rib rests on the tank's top, as shown.
11
Step 3:Dry Fit Riser to Adapter
Step 3a: Dry fit the riser to the adapter.
• Make sure riser penetrations are the right sizes and in the correct locations.
Step 3b: If the riser is higher than 3 inches (75 mm) above the estimated final
grade,cut it to size per the instructions in Step 2.
Step 3c: If the riser is too short, use an Orenco grade ring to extend it. Riser prep for 500-gal.(2000-L)Orenco FRP tanks

Instruction Set 6:Riser Watertightness Testing
Watertightness test
IMPORTANT A watertight tank and watertight riser-to-tank connections are
critical for the wastewater system to function effectively and efficiently.
Step 1:Prep for Test a Access riser
Step 1 a:Make sure the adhesive seams have set and the tank has been backfilled o- -
according to the manufacturer's instructions—typically to the tank's midpoint. 4 Fill the tank to a
• level 2 in.(51 mm) -
Step 1b: Plug the inlet(and outlet, if present)of the tank with watertight plugs. I into the riser
Step 1c: Fill the tank with water to a level 2 inches(51 mm) into the riser. o- 2 in.
Tank brim T (51 mm)
Step 2:Test Watertightness
Step 2a: Wait for the required time before inspecting the riser-to-tank
connections for leakage.
• Follow the tank manufacturer's recommendations(or applicable local regula-
tions)for wait times before inspecting the tank for leaks.
• Orenco recommends at least 30 minutes for its fiberglass tanks.
Step 2b: Check for any drop in the liquid level inside of the riser and any visible
leakage from the riser-to-tank connections.
• At the end of the test,there should be no drop in liquid level and no visible
leakage from seams, pinholes, or other imperfections.
• If leaks are found during the test,seal the leaks and repeat the test.
Step 2c: Once the riser-to-tank connections are proven watertight, remove the
plug(s) and drop the water level in the tank to just below the invert of the inlet or
outlet,whichever is lower.

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. 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.(Contact your Dealer for assistance.)

Raw sewage enters the septic tank through its inlet tee.In the septic tank,the raw sewage separates into a scum layer,a sludge layer,
and a clear zone. 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.

HI yi �I7 • Deadmen are recommended for all installations.
1,: • Deadmen are required if there is a potential for groundwater to be pres-
18-24 in. ent in the excavation at any time,or if surface runoff can fill the excava-
(460-600 mm) tion at any time, resulting in a"bathtub"effect.
o �l', P. " Note:This effect occurs in dense soils when water fills an excavation
1 during surface water runoff—usually during a heavy rain event—
before the disturbed soil in the excavation has had time to settle.
• If you are unsure whether to install antibuoyancy deadmen or not, con-

Step 5b: Installing Concrete Deadmen
Notes:
• We recommend preparing concrete deadmen off site before installation.
•PVC forms for concrete deadmen can be made from 12-in. dia. x 4-ft
long(300-mm x 1200-mm long)PVC half-pipe or chamber material.
• Wooden forms for concrete deadmen can be built 12-in. wide x 6 in.
tall x 4 ft long(300-mm x 150-mm x 1200-mm).
Step 5b(i): Fill two forms halfway with concrete.
Step 5b(ii): Place two#4 reinforcing bars in each of the forms.
Step 5b (iii): Finish filling the forms.
Step 5b (iv): Sink eyebolts from the antibuoyancy hardware kit into the
concrete for attaching the deadmen later.
Step 5b (v): Let the concrete set completely before moving the deadmen.
Step 5b(vi):Use appropriate lifting gear to set the deadmen in place.
Step 5b (vii):Secure the deadmen along the length of the unit,on both
sides,with the antibuoyancy hardware kit and make sure they are level.
Step 6:Partially Backfill Excavation(s)

*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.

Using a Pump Curve
A pump curve helps you determine the best pump for your system.Pump curves show the relationship between flow and pressure(total dynamic
head,or TDH),providing a graphical representation of a pump's optimal performance range.Pumps perform best at their nominal flow rate.These
graphs show optimal pump operation ranges with a solid line and show flow rates outside of these ranges with a dashed line.For the most accurate
pump specification,use Orenco's PumpSelect-software.

Installation Instructions
The float switch assembly is typically mounted in the screened pump vault or effluent screen inside of a septic or dosing tank.
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

Step 7:
When used with an Orenco electrical splice box:
Push the level control wires through the watertight cord grips into the 11,
electrical splice box.Leave an adequate length of electrical cable coiled ` 1 -mkt
inside the riser to allow for easy removal of the pump and float switch it;
assembly.Do not remove the colored markers or the paper tags from the i '
float cables,and do not try to thread the markers and tag through the �,o
cord grip.Tighten the cord grips by hand,not by tool,then test the tight-
ness of the cord grips by tugging on each cable.A cable is secure when
the cord grip is tight enough to prevent slippage.Adequate lengths of
cable should be left within the splice box to allow easy removal for future
disconnecting and resplicing.
Note: See the splice box instructions(EIN-SB-SB-11 and
corresponding splice box diagram for connection instructions.

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.
