RE: Application for Discharge System—Ball Property
3213 Colby Chase Drive, Apex,NC 27539
Dear Mr. Hennessy,
Enclosed please find information supporting an application for a discharge system for a 4-
Bedroom Single-Family Residence (SFR) located in Wake County, North Carolina. Coverage
under this permit is sought to replace an existing pressure manifold system.
An existing pressure manifold system serves a residence located on the subject property. The
existing system is failing. The site has been deemed unsuitable for ground absorption sewage
treatment systems by the Wake County Health Department due to insufficient space. The
proposed system is to be sized for 4 bedrooms at 90 gallons per day per bedroom (360 gallons
per day) and has been designed to convey all wastewater from the SFR, including greywater, to
the septic tank.
The following information is included with this letter:
Notice of Intent(NCG550000). Attachment A.
$60 check payable to North Carolina DENR.
- Documentation from Wake 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 Jeff Vaughan of AWT, Inc. Attachment E.
Correspondence from USGS. Attachment F.
- Flow Path to"Blue Line" Water Feature.Attachment G.
o Signed Easement
Engineering Alternatives Analysis(EAA).Attachment H.
Local Government Review Forms. Attachment I.
Plans and Specifications for the proposed system. Attachment J.

The proposed discharge point is in an un-named tributary of Middle Creek, located on a
neighboring property owned by Merion Subdivision. An easement was written to allow
the discharge pipe to cross the neighboring property to get access to the un-named
tributary. The un-named tributary then flows into Middle Creek. The discharge system
will utilize the following components:
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 Middle Creek. Flow will
be conveyed through the discharge pipe to an un-named tributary and a series of
stormwater culverts until it reaches Middle Creek (to the southeast), the Blue Line
feature. A map showing the path from the discharge point to the first "blue-line" stream,
as shown on the Wake 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. Jessica Sloan,
Water Resources Program Coordinator of the Town of Apex Water and Sewer Operations
Department, has indicated that sewer is not currently available for the applicant's
property and there are no plans to extend sewer at this time. The closest sewer system is
located approximately 0.55 miles from the applicant's property.
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 Wake County Health Department indicated that the site is unsuitable for installation
of a ground absorption septic system in letter dated September 4, 2020. (Attachment B).
The letter indicated that an improvement permit cannot be issued due to insufficient
space and poor soil characteristics.

� a
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 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 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 H. 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
- Insufficient space and inadequate soil for a subsurface
absorption system.
c.) single-family residence wastewater irrigation (drip and spray)
- Insufficient space for a non-discharge ground absorption
system.
d.) reclaimed-water systems
- Insufficient space 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 form submittals is included as Attachment I. To date,
the completed forms have not been received.
Plans and Specifications
Plans and Specifications for the proposed system are included as Attachment J.

Dear David Ball:
This letter is to inform you that a site evaluation was conducted on the above referenced property on
9/2/2020.This property was determined to be Unsuitable for the use of a subsurface sewage treatment and
disposal system in accordance with the"Regulations Governing Wastewater Treatment and Dispersal
Systems in Wake County"(and 15A, Subchapter 18A,Sections.1901-.1969 of the North Carolina
Administrative Code,adopted by reference in the Wake County Regulations).
The site evaluation findings revealed the following limiting factors:
❑Unsuitable topography and/or landscape position, .1940
E Soil Characteristics Morphology, .1941 Soils demonstrated Expansive Minerology and Block Like to
Lack of Structural Peds.
❑ Soil Wetness Condition, .1942
❑ Soil Depth, .1943
❑Restrictive Horizons, .1944
E Available Space, .1945 .1945 Lack of available space due to two previous systems that have been
installed and failed.
❑Other:
Please refer to the enclosed soil evaluation form and site plan for additional information related to
limiting factors.
The Regulations allow for the reclassification of unsuitable sites to provisionally suitable status if the
conditions of 15A NCAC 18A,Section.1948(d)are met. "A site classified as UNSUITABLE may be
used for a ground absorption sewage treatment and disposal system specifically identified in Rules.1955,
.1956,or.1957 of this Section or a system approved under Rule.1969 if written documentation, including
engineering,hydrogeologic,geologic or soil studies,indicates to the local health department'that the
'Wake County Environmental Services Department

proposed system can be expected to function satisfactorily. Such sites shall be reclassified as
PROVISIONALLY SUITABLE if the local health department determines that the substantiating data
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."
You have two options available. First,you may hire a soil scientist to evaluate your property(PIN#
0750375348)and submit a proposal(layout and waste water design)to Wake County Environmental
Services. Second,you may also appeal this decision with submission of adequate substantiating
documentation under the provisions of North Carolina General Statute(NCGS). 130A-24(b)&(c)and

MEMORANDUM
TO: Mr. David Ball
FROM: Jeff Vaughan, L.S.S.
SUBJECT: Soils Evaluation for 3213 Colby Chase Drive
Apex,NC (Wake County)
A soils evaluation was conducted for the property located at 3213 Colby Chase Drive, Apex,NC
(Wake County). The evaluation was conducted by Jeff Vaughan,LSS of AWT on June 17,2020.
A failing subsurface septic system is located on the property and currently serves the 3-bedroom
single-family residence located on the site. The septic system is located to the south of the
residence. The site has been deemed unsuitable for a ground absorption sewage system by the
Wake County Department of Environmental Services.
The existing system on the property impedes the potential for a septic application area in the back
yard.The lack of space would also hinder the potential to permit a subsurface or surface application
wastewater system. The property also has a history of failing systems.
The subject property is unsuitable for subsurface and surface application wastewater systems due
to 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.

Ms. Davidson,
In response to your inquiry about the 7Q10 low-flow characteristic for a "ditch/drainage" or unnamed tributary to Middle Creek
between Apex and Holly Springs in south central Wake County, the following information is provided:
A check of the low-flow files here at the USGS South Atlantic Water Science Center(Raleigh office) does not indicate a previous low-
flow determination for the point of interest, identified by the lat/long coordinates (35.69209, -78.82182) provided via email dated
07/03/2020 from the DWR USGS Low Flow portal following your request submission.
No USGS discharge records are likewise known to exist for the point of interest.

8/26/2020 Agriwaste Technology. Inc. Mail-Fwd: USGS response to DWR USGS Low Flows request#2020-71 (dated 2020/07/03)for UT Middle Creek Wake County...RE:[EXTERNAL]Low-flow re...
In the absence of site-specific discharge records sufficient for a low-flow analysis, estimates of low-flow characteristics at ungaged
locations are determined by assessing a range in the low-flow yields (expressed as flow per square mile drainage area, or cfsm) at
nearby sites where estimates have been determined.
A basin delineation completed using the online USGS StreamStats application for North Carolina (https://streamstats.usgs.gov/ss/)
indicates the drainage area for the point of interest (StreamStats adjusted coordinates 35.69208, -78.82181 NAD83) is 0.0623 sqmi,
which confirms the drainage area submitted as part of the request information.
For streams in south central Wake 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/2015/50011. 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 a small basin area upstream from the point of interest. As

interest very near the transition from the poorly drained soils (Triassic basin geologic unit) to the moderately well-drained soils
underlain by granitic rocks more characteristics in central Wake County.
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.
'Assessing the occurrence of zero or minimal 7Q 10 discharges in the central section of the study area is more complex. This large
area is composed of streams draining to the Neuse River between its confluences with New Light Creek (Wake County) and
Contentnea Creek (pl. 1). The dominant soils in this area are well and moderately drained (fig. 6B). Even though categorized as
moderately drained soils, occurrences of soils having some poor drainage (A/C group, table 3) are present in the Black Creek and
Hannah Creek Basins from extreme southern Wake County into southern Johnston County. Other occurrences of poorly drained
soils are present along reaches of the Neuse River, Contentnea Creek, and along other smaller streams draining basins known to be
swamp terrain. Sites having a 7Q10 discharge of zero and large drainage areas (288, 301, 406, 408, and 410) mostly occur in the
basins occupied by poorly drained soils or characterized as swamp. Among the sites in this area of moderately and well-drained
soils having zero or minimal 7Q10 discharges, drainage areas range from about 1 mi2 (site 154) to nearly 82 mi2 (site 288, Black
Creek subbasin). Because many other sites in this area with drainage areas in this same range have 7Q10 discharges exceeding
minimal levels (greater than 0.05 ft3/s), it is difficult to identify areas that may be considered "zero-flow"zones. Where poorly drained
soils are the predominant factor at sites in the upper and lower ends of the study area, the magnitudes of low flows in the central
section appear to be affected by a combined set of factors which include soils, degree of terrain slope, and drainage area. Assessing
the potential for the 7Q10 discharge being zero in the central section of the study area will, for a given site, require an examination of
the low-flow characteristics listed for nearby sites (tables 6, 7)."
Consideration of the above information (in particular, the small drainage area of 0.06 sqmi) 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.

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 un-
named tributary of Middle Creek. 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 4-Bedroom Single Family Residence(SFR) located in
Wake County,North Carolina. The proposed system will replace a failing subsurface conventional septic system
that currently serves the residence. The proposed discharge point is in an un-named tributary of Middle Creek
located to the south of the applicant's property. The proposed treatment system will utilize the following
components:
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(90 gpd/bedroom)with a
flow of 360 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.
EAA Guidance Document Revision:April 2014
Page 2 of 8

Response: Connection to a sewer collection system is not feasible for this facility. Jessica Sloan, Water Resources Program
Coordinator with the Town of Apex,indicated that sewer is not currently available for the applicant's property
and there are no plans to extend sewer at this time. The closest sewer system is located in the Pemberly
Subdivision and is approximately 1900' feet away. 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$190,000.
Additional costs including the cost of the pump station(if needed),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 indicated above, a regional sewer system exists within a five mile radius of the applicant's property, but the
Town of Apex has no plans to extend their coverage area toward the applicant.
Alternative B. Land Application.
Land application disposal alternatives include individual/community onsite subsurface systems, drip
irrigation,and spray irrigation.
1. Provide an estimate of the best case hydraulic loading rate based on County Soil Surveys or from
a soil evaluation performed by a soil scientist. Include calculations showing the hydraulic
loading rate and the total area of land needed for the land disposal system,including buffers.
Response: Wake County Department of Environmental Services indicated that the site is unsuitable for installation of a
ground absorption septic system in a letter dated September 4,2020(Attachment B of application package). The
letter indicated that a permit cannot be issued due to insufficient space and unsuitable soil conditions.
Per the soil evaluation by Jeff Vaughan of Agri-Waste Technology, Inc.the site does not have adequate space 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 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 on-site soils
are mapped as a Georgeville Silt Loam. However,the on-site soils inspection indicated that the soils present on
the site are not indicative of the mapped soil type. The soils on site are very restrictive for wastewater systems.
For a subsurface system in this soil,a drip system with pretreatment would be required. These soils would have
a long-term acceptance rate (LTAR) ranging from 0.05-0.15 gpd/sq.ft., with a typical rate of 0.1 gpd/sq.ft.
Subsurface systems also require the drainline to be installed with the contour so that each drainline is at a
constant elevation. This results in a"fanning"of the drainline and requires additional space in order to install the
required amount of drainline. The sizing calculation is summarized in the table below:

Estimation for Topographical Variation 1,200 sqft
Estimated Area Required (Actual) 4,800 sqft
Approximate Area Available 2,181 sqft
The current property's land available for the system is 2,181 sqft,due to setbacks and existing site conditions.
A schematic of this area is shown in Appendix A of the EAA. The land needed for a subsurface dripfield
design is a minimum of 4,800 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 Georgeville Silt Loam. However, the on-site soils inspection indicated that the soils
present on the site are not indicative of the mapped soil type. The soils on site are very restrictive for
wastewater systems. For a surface system in this soil, the SFR loading rate group is likely restricted to a
maximum annual loading of 13 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 360 gpd =90gpd*#bedrooms
Surface Loading Rate 13 in/year
Minimum Area Required (Nominal) 16,215 sqft
Approximate Area Available 10,757 sqft
The current property's land available for a surface drip or spray system is 10,757 sqft, due to setbacks and
existing site conditions. This available area calculation assumes that property line setback waivers could be
acquired. Without property line setback waivers, there is no area available for a non-discharge system. A
schematic of this area is shown in Appendix A. The land needed for a non-discharge application system is
estimated at 16,215 sq.ft.,so there is insufficient space for this type of system at the residence. The potential
waving of property setbacks was taken into account when considering the available application area for both
surface systems. There is not sufficient land available for this option.
2. Assess the availability of land. If insufficient land is available onsite, assume that the necessary
land can be purchased and estimate the land purchase cost based on local real estate prices.
Alternatively,provide documentation to demonstrate that insufficient land is available for sale in
the project area (include letters from adjacent property owners indicating no interest in selling
property).
Response: Because insufficient land is available onsite (due to inadequate soil and space), offsite land was reviewed.
The table below lists neighboring properties and the value of the land as listed by the Wake County GIS
website. The values listed in the table do not reflect the value of the single-family residences. The soil type
listed for these Georgeville(GeB2). However,we expect these properties would also exhibit the poor soil
characteristics shown by the subject property. These sites will be very restrictive for wastewater systems.
The vacant property to the south is the deeded open space for the subdivision. Acquiring off-site land is not
an option for this property.

3. Provide a description of the wastewater treatment system and the non-discharge application
system. Include a site plan showing the proposed layout, the application area, any existing
structures,proposed structures, and other uses within the site.
Response: A typical subsurface drip system or a non-discharge surface spray or surface drip system with pretreatment
considers the following components:
-Septic Tank with Effluent Filter
-Recirculation Tank(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)with addition of fill soil
Note:The proposed discharge system does not consider the pump tank,headworks box or disposal field.
Site drawings of these alternative systems showing the available application area are included as Appendix A
of the EAA. Due to the cost requirements of a drip or spray system and the lack of sufficient soil,there is no
ability to consider any of these systems on this property.
4. Explain the proposed reuse plan if reclaimed water will be used by a third party.
Response: There is no reuse plan being considered either on-site or by a third party. The residential plumbing
infrastructure does not allow for reuse in the proposed 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. While there may be area available to
utilize reclaimed water, between the soils on site and the cost, it would be infeasible to utilize reclaimed
water for this facility.
On-Site Utilization of Reclaimed Water
Daily flow through system 360 gpd
Available Area to Irrigate 16,500 sqft *Veg.cover on properly
Application Rate 0.5 in/week *Fescue Grass
Acceptable Volume to Irrigate 688 ft3/week
735 gpd
EAA Guidance Document Revision:April 2014

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.
Response: The treatment systems specified above in Step B would meet the treatment standards required by these rules
as they pertain to single family residences. However, due to the restrictions listed above, no land-based
systems can be considered.
8. Note: Proposed discharges from groundwater remediation systems must evaluate the potential
for an infiltration gallery treatment alternative.
Response: N/A
Alternative C. Wastewater Reuse.
You must evaluate reusing all or a portion of the wastewater generated. Some municipalities are currently
reusing wastewater within the confines of their WWTP property for irrigation, toilet flushing,backwashing,
etc.,while other municipalities have established progressive reuse programs for residential irrigation. Reuse
applications might include golf course irrigation, crop irrigation (e.g., hardwood or pine plantation,
grasses), athletic field irrigation, landscape uses, and commercial/industrial uses. Some of these reuse
applications will be evaluated under Alternative B, Land Application. The design of reclaimed water
systems must meet the treatment and design requirements specified in 15A NCAC 2U.
Response: All reuse applications for this project scale were evaluated under Alternative B,Point 4. Wastewater reuse
was determined to be infeasible for this project.
Alternative D. Direct Discharge to Surface Waters.
1. No new or expanding (additional) discharge of oxygen-consuming waste will be allowed to
surface waters of North Carolina if both the summer 7Q10 and 30Q2 streamflows are estimated
to be zero,in accordance with 15A NCAC 2B.0206(d). Private applicants must contact the USGS
in Raleigh at 919-571-4000 and obtain (generally for a nominal fee),the receiving streamflow data
(s7Q10,30Q2, annual average streamflow) at the proposed discharge location. This information
must be included in the EAA,and will be used to develop permit limits.
Response: Because this is an 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.
EAA Guidance Document Revision:April 2014
Page 6 of 8

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/I. 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/I 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 J (of application package).
4. Provide documentation of the availability of required land and/or easement agreements.
Response: N/A
5. Conduct a Present Value Cost Analysis per STEP 4.
Response: A Present Value Cost Analysis for the discharge system is included in Appendix B. A summary of the
analysis is included in STEP 4.
6. Note: All direct discharge treatment systems must comply with Reliability Requirements
specified in 15A NCAC 2H.0124.
Response: The system serves a private facility that is served by a well and does not have elevated water storage tanks.
In the event of a power outage, water may still 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 installation
cost does not include the cost of fill soil that may need be added,at the direction of a L.S.S.,to maintain
suitable soil depths within a surface irrigation field. The"Present Value of Costs"is based on a discount
factor of 1.2%.

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

Application for Discharge System—Ball Property
4154 Murphy School Road, Durham,NC 27705
Dear Mr. Havens,
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 (SFRs). The proposed system will serve an existing 3-
Bedroom SFR located in Wake County,North Carolina (nearby the Town of Apex). The
proposed system will replace a failed sub-surface system that currently serves the SFR.
The site has been deemed unsuitable for ground absorption sewagetreatment
rp t eatment systems by
the Wake County Department of Environmental Services due to unsuitable soil
conditions and insufficient space. 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.
Please complete the enclosed form for inclusion in the application for the proposed
system. This residence is located in Wake County. Please note that this form is only
meant to determine zoning/jurisdiction information for the town 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.

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 1,250-gallon septic tank will be installed for this system. The existing 1,000-gallon tank will
be abandoned in place. An Orenco 8" Biotube effluent filter will be installed in the outlet end of the
septic tank. 24"access risers will be installed on both the inlet and outlet ends of the septic tank. All
wastewater from the single-family residence, including greywater,will be routed into the septic tank.
Waste that exits the septic tank will flow via gravity 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 then exits the AX-RT unit via
gravity to the discharge outlet after passing through the UV disinfection system within the AX-RT
unit.
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,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 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 stream located in the center ofthe property. 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
ODetermine 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 -4.-\
settling and 1 inch (25 mm)for ensuring drainage away from the riser.
O � . •.•...••• !..• r
Step 2:Cut Riser to Size (if Necessary) o •o' ; • I.'.
!
If the riser needs to be cut to size, cut it with a circular saw or table saw. o o•Qd�p 9
,•
• Always cut excess length from the bottom of the riser.
• For square, even cuts,a good fit,and a watertight joint between the riser , .
and the adapter, use an Orenco riser-cutting saw guide. '�, O 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.
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

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-
tons)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.

Installation, Operation and Maintenance Instructions
FT08 Models and All Base Inlet Models
U.S. Patent Nos. 5294635/ 4439323
Installation Instructions:
The Biotube Effluent Filter is suspended in the septic tank by the 4"outlet pipe.The filter is composed of a
vault body that will be fixed to the discharge pipe and a removable cartridge that consists of the Biotube
filter cartridge and the extendible handle.
1. Test-fit the effluent filter on the 4"out-
let pipe without gluing. Make sure that
it fits plumb.
Any existing outlet tee will have to be
removed.
II t
‘rri-
2. Ensure sufficient clearance for trouble-
free servicing of filter cartridge. Install
assembly near the tank wall to reduce I'
any stresses that may be caused by
maintenance.
Sufficient room between the access port and filter should be provided for
easy removal of solids from the tank.
The cartridge will need to be removed
and cleaned while the tank's solids
content is being pumped-out.

3. Once the filter has been fitted properly,
apply primer and PVC cement to the
outside of the outlet pipe and the filter's
4" outlet.Use a multipurpose cement if
the outlet pipe is ABS. Do not use l
primer on ABS. -,
Optional:Stainless steel set screws
may be used instead of glue.
4. Slide the effluent filter onto the 4" pipe
and plumb vertically.
5. Hold the filter in position until the adhe-
sive has time to set(approximately 20 1;
seconds). 1
6. Extend the handle of the cartridge to an I �i
elevation above the top of the tank for
easy access. Use 3/4" schedule 40 PVC
for extension.
Either use the stainless steel set
screws or glue the extensions in place.

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.
AiKey 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.

•The seam between the tank and the tank adapter has to be watertight.
• Watertight seams and penetrations are critical for proper performance.
• Before installing the riser, make sure the riser is the correct height—the
recommended riser height is 2-3 inches(50-75 mm) above final grade.
• Before installing the riser, make sure that the riser penetrations are made
at the correct height to make connections.
• Before installing the riser,make sure the penetrations are aligned correctly.
•After installing the riser,make sure all adhesive seams are smooth,con-
tinuous fillets,free of voids.
•After installing the riser,make sure the adhesive is set before continuing.
Step 8: Test Tank and Adapter Seams For Watertightness
Step 8a: Test the tank for watertightness if it has not been tested already.
Note:Follow the manufacturer's recommendations for watertight-
ness testing.Some manufacturers require the tank be fully backfilled
before testing watertightness.
Step 8b:Test the tank-to-riser adapter seams for watertightness.
• Use PVC Access Riser Installation(NIN-RLA-RR-1) instructions to test the
seams between the access riser,tank adapter, and tank for watertightness.
41 Key Points:
• Watertight seams are critical for proper system performance—all tank-
to-riser seams must all pass the watertightness test before you continue.
• Follow all applicable regulations and manufacturer's instructions for water-
tightness testing.

Step 16e: Be sure the septic tank's access lids are secured.
As described in OSHA Standards(29 CFR,Part 1926,Subpart P,Appendix A),noncohesive soils
or granular soils include gravel,sand,or silt with little or no clay content.Granular soil cannot be
molded when moist and crumbles easily when dry.Cohesive soils include clayey silt,sandy clay,
silty clay,clay,and organic clay.Cohesive soil does not crumble,can be excavated with vertical
sideslopes,is hard to break up when dry,and when moist,can be rolled into threads without
crumbling.For example,if at least a 2-inch(51-mm)length of 1/8-inch(3-mm)thread can be
held on one end without tearing,the soil is cohesive.

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,orTDl-),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.

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 4
function of the float. Make sure that your float cable color markers corre-
spond with the wiring diagram provided. If the wiring diagram does not — Float function
match your float cable marker colors, contact Orenco Systems® Inc. or color marker

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.

Residential Flow Reduction Approval
Wake County
Dear Mr.and Ms. Ball:
Per the proposed water use data based on the usage of low-flow fixtures and appliances as well as historical
water usage data provided by Agri-Waste Technology, Inc.,the Division of Water Resources hereby approves
the use of a 360 GPD design flow for the existing 4-bedroom home located at 3213 Colby Chase Drive in
Wake County. Please note that approval of this flow reduction does not constitute a modification to any
previously issued permits nor issuance of a new permit.
Regardless of the adjusted design daily wastewater flow rate, at no time shall the wastewater flows exceed
the effluent limits defined in the non-discharge permit for the treatment facility or exceed the capacity of the 1
sewers downstream of any new sewer extensions or service connection(s).
The granting of this flow reduction does not prohibit the Division from reopening, revoking, reissuing and/or
regulation the flow reduction as allowed by the laws, rules,and g ulation contained in 15A NCAC 02T, NCGS
143-215.1, or as needed to address changed in State and/or Federal regulations with respect to wastewater
collection systems, protection of surface waters and/or wastewater treatment.
If you have any questions, please contact Christyn Fertenbaugh, P.E. via email at
