RE: Letter Requesting Coverage under the General Permit—Hunt Property.
3007 Redwood Road,Durham,NC 27704
Dear Mr.Weaver,
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 3-Bedroom Single Family Residence
(SFR) located in Durham County, North Carolina. The proposed discharge system will replace
the unpermitted 3-bedroom system that serves the residence. Christopher McGee, LSS, Agri-
Waste Technology, Inc., has deemed the site unsuitable for ground absorption sewage treatment
systems due to inadequate soil conditions and unsuitable topography. The proposed system is to
be sized for 3 bedrooms at 360 gallons/day. The residence is located at 3007 Redwood,Durham,
NC 27704.
This is being submitted with the intent to have coverage under the NCG55 General Permit.
Coverage under this permit is sought to replace an unpermitted sand filter system.
The following information is included with this letter:
- NCG55OOOO. Attachment A.
$60 check payable to North Carolina DENR.
- Documentation from Durham County Attachment B.
- Soils Evaluation report by Chris McGee of AWT,Inc. Attachment C.
- Correspondence from USGS. Attachment D.
- Flow Path to"Blue Line"Water Feature.Attachment E.
- Information on Connecting to Regional Sewer. Attachment F.
Engineering Alternatives Analysis(EAA).Attachment G.
- Local Government Review Forms. Attachment H.
- Process Flow Schematic Attachment I.

The existing sand filter system at the Hunt residence is piped together with the system
that is located at 4712 Mannix Road, Durham, NC 27704. The property located at 4712
Mannix Road currently has an existing discharge permit (NCG550790). The flow path of
the current system can be seen in Attachment E. Upon issuance of the Certificate of
Coverage, the new design would relocate the discharge point to a roadside ditch along
side Mannix Road that also has an existing Certificate of Coverage under permit
NCG551232. This discharge point is located in the right-of-way for Mannix Road, but to
access the roadside ditch, an easement will be issued to cross the property located at 4712
Mannix Road, Durham, NC 27704. The flow path that is being proposed can be seen in
Attachment E. The discharge system will utilize the following components:
- Septic Tank with Effluent Filter
- AdvanTex AX-20 RT Pod
- Re-circulation Pump Chamber(Integrated into AdvanTex Pod System)
- UV Disinfection
- Discharge Point with Rip-Rap
Flow Path to"Blue Line"Water Feature
The proposed discharge location is in a roadside ditch, a parcel away, that has an
existing certificate of coverage that serves 3011 Redwood Road, Durham, NC
27704. This roadside ditch flows into an unnamed tributary to Panther Creek in
the Neuse River Basin. A map showing the path from the discharge point to the
first existing certificate of coverage area, as shown on the Durham County GIS
data,can be seen in Attachment E.
NCG550000
As part of the application,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.
- Durham County Documentation
- 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. Engineering
Services of the Durham Public Works Department, indicated that the property is not
within the city's coverage area. The closest current city-maintained sewer is
approximately 2,800 linear ft. from the property and there are no immediate plans for a
sewer extension to the area at this time (Attachment F). 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$280,000.
Durham County Documentation
The original sand filter permit issued by Durham County Health Department is included
in Attachment B. The system has a history of malfunctioning. The NCDEQ has issued

t ,
multiple Pump and Haul permits for the Hunt property. This indicates that the sand filter
system that currently serves the property is underperforming. (Attachment B).
Investigate Land Application such as spray irrigation or drip irrigation.
Per the soil evaluation by Chris McGee of Agri-Waste Technology, Inc. the site does not
have sufficient space or suitable soil characteristics to accommodate a non-discharge
surface spray or drip wastewater system(Attachment C).
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
a roadside ditch that leads to an unnamed tributary to Panther Creek. The analysis from
USGS indicates the 7Q10 discharge for the point in question is likely zero (Attachment
D).
Engineering Alternatives Analysis
An Engineering Alternatives Analysis (EAA)has been completed for this site and
is included as Attachment G. In my opinion, the completed EAA demonstrates
that a wastewater treatment system permitted under the NCG550000 General
Discharge Permit is the only feasible option for this site. We have exhausted all
other options for this site as follows:
a.) connection to a municipal or regional sewer collection system
- Not feasible due to costs.
b.) subsurface disposal
- No suitable soil for a subsurface absorption system.
c.) single-family residence wastewater irrigation (drip and spray)
- Unsuitable soil and insufficient space for a non-discharge
ground absorption system.
d.) reclaimed-water systems
- No suitable soil for a reclaimed water system. No
reasonable ability to operate as a bulk distributor of
reclaimed water.
e.) Any viable combination of the above
- There are no viable combinations of the above due to soil
and cost limitations.
Local Government Review Forms
As part of the EAA, Local Government Review Forms were sent to Durham County and
the City of Durham. A copy of the submittal is included as Attachment H.

MEMORANDUM
TO: Mr.David Hunt
FROM: Chris McGee,LSS
Gary Morehouse,Associate Soil Scientist
SUBJECT: Soils Evaluation for 3007 Redwood Road, Durham,NC. 27704
Agri-Waste Technology, Inc. (AWT) was contracted to perform a soils evaluation for the
purpose of an on-site wastewater system suitability at the subject property in Durham, NC. The
evaluation was performed by Gary Morehouse of AWT on August 14, 2019. A single-family
residence with a non-state permitted sand filter discharge wastewater system is located at 3007
Redwood Road. The existing system is crossing over a neighboring property to discharge.
The soils on the subject property is unsuitable for subsurface and surface application
wastewater systems due to lack of suitable topography, limited space, shallow wetness
conditions, and shallow depth to expansive clay mineralogy. 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.
Sincerely,
Civi. /14-1,--

Subject: Re: Low-flow request approval
Ms. Davidson,
In response to your inquiry about the 7Q10 low-flow characteristic for a "roadside ditch" to an
unnamed tributary within the Panther Creek basin near Glen Forest (vicinity of Durham) in east
central Durham 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 (36.03326, -78.80028) provided via email dated 03/04/2020 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.
In the absence of site-specific discharge records sufficient for a low-flow analysis, estimates of low-
flow characteristics at ungaged locations are determined by assessing a range in the low-flow
yields (expressed as flow per square mile drainage area, or cfsm) at nearby sites where estimates
have been determined.
A basin delineation completed using the online USGS StreamStats application for North Carolina
(https://streamstats.usgs.gov/ss/) indicates the drainage area for the point of interest (StreamStats
adjusted coordinates 36.03324, -78.80028 NAD83) is 0.03 sqmi.
For streams in east central Durham County, low-flow characteristics published by the USGS
are provided in the following reports:
(1) The first is a basin-wide report for the Neuse River basin published in 1998. It is USGS Water-
Resources Investigations Report 98-4135, "Low-flow characteristics and discharge profiles for
selected streams in the Neuse River basin, North Carolina" (Weaver, 1998). The report is
available online at http://pubs.usgs.gov/wri/1998/4135/report.pdf. This report provides low-flow
characteristics (based on data through 1996)for USGS continuous- and partial-record sites in the
Neuse River basin where sufficient data was available for analyses. However, the report does not
provide statistical relations for estimating low-flow characteristics at ungaged locations.
(2) The second is a statewide report published in March 2015. It is USGS Scientific Investigations
Report 2015-5001, "Low-flow characteristics and flow-duration statistics for selected USGS
https://mail.google.com/mail/u/1?ik=75462b5a03&view=pt&search=all&permthid=thread-f%3A1665948723928993345&sim pl=msg-f%3A16659487239... 2/5

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.
Low-flow characteristics estimated for point of interest:
Visual inspection of the stream location on a topographical map suggests a very small basin area
upstream from the point of interest. As noted above, the drainage-area for the basin upstream
from the point of interest is 0.03 sqmi.
On pages 33-34 of the Neuse basin-wide low-flow report (first reference above) is information
about the Occurrence of Zero or Minimal 7Q10 Discharge that is likely to occur for a stream within
the major basin, contingent on the size of the upstream drainage basin. The discussion on page
33 in this section indicates that poorly drained soils (that is, soils having low infiltration rates) is a
primary factor in numerous occurrences of zero 7Q10 discharges in the upper end of the study
area [Neuse River basin]:
"Much of the water that comes in contact with the soils in this area most likely enters the streams
as overland runoff and does not infiltrate into surficial aquifers for later release during drought
conditions. Among sites having zero 7Q10 discharges, the drainage areas range from less than
0.01 mi2 (site 10) to about 44 mi2 (site 121). For sites in this area having non-zero 7Q10
discharges, the average 7Q10 unit low flow is about 0.005 (ft3/s)/mi2. Therefore, sites with
drainage areas less than about 10 mi2 could be expected to have zero or minimal 7Q10 discharges
(less than 0.05 ft3/s)."
Additionally, the basin upstream from the point of interest is underlain by the Triassic basin
geologic unit. From a hydrologic perspective, streams underlain by this geologic unit have very
little to no potentials for sustained base flows during extended dry periods. At sites underlain by
the Triassic basin where the USGS has collected sufficient records for low-flow analyses, the low-
flow characteristics for sites having drainageareas that would typically be expected to have
sustained flows actually have some of the lowest low-flow estimates in the state.
Consideration of the above information results in a conclusion the 7Q10 discharge for the point of
interest is zero flow.
Please understand the information provided in this message is based on a preliminary assessment
and considered provisional, subject to revision pending further analyses.
This low-flow response is provided via the DWR USGS Low Flows cooperative agreement
between the USGS and the N.C. Department of Environmental Quality, Division of Water

Good afternoon Kristy,
City sewer is not available to 3007 Redwood Rd.The closest existing sewer lines (green lines in the image
below) lie roughly 2,800 ft. away near the corner of Cheek Rd. and Ardsley Dr. As of this date,there are no
plans to extend sewer towards 3007 Redwood that our office is aware of.

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 a roadside
ditch off of Mannix Road. Effluent leads north east in the ditch and empties into a tributary to Panther Creek.
The analysis from USGS indicates the 7Q10 discharge for the point in question is likely zero (Attachment D of
application package).
All applicants.
If you conclude that the proposed discharge will pass the "allowable discharge" criteria, then begin the EAA
preparation by summarizing the following general information about the proposed project:
• Provide a description of the proposed project. If the project will be constructed in phases, provide a
schedule for constructing each additional phase, and provide the projected flow per phase (see STEP 2).
Response: A wastewater discharge system is to be constructed for a 3-Bedroom Single Family Residence (SFR) located in
Durham County, North Carolina. The proposed system will replace an unpermitted sand filter discharge system
that currently serves the residence. The proposed discharge point is in a roadside ditch located off the property to
the northeast, which leads to an unnamed tributary to Panther 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 3 bedrooms.
For the 20-year planning period,the system will be designed for a 3-bedroom residence with a flow of 360 gallons
per day. At 2 people per bedroom,the system will be designed to serve 6 residents.
STEP 3. Evaluate technologically feasible alternatives
Alternative A. Connection to an Existing Wastewater Treatment System.
You must evaluate the feasibility of connecting to an existing wastewater treatment system served by a
municipality or other entity holding a valid NPDES or Non-Discharge Permit. All connection options
should include an evaluation of a gravity line and/or force main with pump station(s).
1. Existing Sewerage System:
(a) Identify whether there are existing sewer lines within a five-mile radius,or consider a greater
radius if cost effective for the project size.
Response: Connection to a sewer collection system is not feasible for this facility. Engineering Services of the Durham
Public Works Department indicated that the property is not within the city's coverage area. The closest current
EAA Guidance Document Revision:April 2014
Page 2 of 8

city-maintained sewer is approximately 2,800 linear ft. from the property and there are no immediate plans for a
sewer extension to the area at this time(Attachment F). 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 $280,000.
Additional costs including the cost of the pump station, potential "tap"or sewer capital fees, road repair costs,
frontage fees and fees for right of way permits would also be incurred by the homeowner.
(b) Provide a preliminary indication of flow acceptance from existing municipal or private
WWTPs under consideration for connection. If a municipal or private WWTP cannot accept
the wastewater, include a letter documenting such and consider this alternative
technologically infeasible.
Response: N/A No sewerage available
(c) If an existing sewerage system will accept the wastewater, evaluate the
piping/pumps/resources necessary to connect to the existing wastewater treatment plant.
Attach a topographic map or a site drawing showing the physical route of this alternative.
Conduct a Present Value Cost Analysis per STEP 4.
Response: N/A No sewerage available
2. Planned Sewerage System: Determine if a regional sewerage system within a five mile radius is
projected to be available within the next five years to receive waste from the project site. If
applicable, determine availability date and flow acceptance projection from appropriate
authority.
Response: As stated above,the City of Durham's sewerage system currently exists within five miles of the property,but a
connection to this system is infeasible due to the cost. According to the Durham Public Works Department,there
are no known plans to bring the city sewer system closer to the applicant's property.
Alternative B. Land Application.
Land application disposal alternatives include individual/community onsite subsurface systems, drip
irrigation,and spray irrigation.
1. Provide an estimate of the best case hydraulic loading rate based on County Soil Surveys or from
a soil evaluation performed by a soil scientist. Include calculations showing the hydraulic
loading rate and the total area of land needed for the land disposal system,including buffers.
Response: 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 C of application package).
Regardless of the fact that a subsurface ground absorption can not be designed or permitted for this site, the
potential size of a subsurface system has been estimated. According to the county soil survey, the site is
classified as a White Store series soil. For a subsurface system in this soil,a drip system with pretreatment would
be required. This White Store soil is a sandy loam soil that would have a long-term acceptance rate (LTAR)
ranging from 0.05-0.2 gpd/sq.ft., with a typical rate of 0.1 gpd/sq.ft. Subsurface systems also require the
drainline to be installed with the contour so that each drainline is at a constant elevation. This results in a
"fanning"of the drainline and requires additional space in order to install the required amount of drainline. The
sizing calculation is summarized in the table below:
EAA Guidance Document Revision:April 2014
Page 3 of 8

Subsurface Dripfield Design Alternative
#Bedrooms 3
Daily Flow 360 gpd =120 gpd*#bedrooms
LTAR 0.1 gpd/sqft
Minimum Area Required (Nominal) 3,600 sqft =Daily Flow/LTAR
Estimation for Topographical Variation 1,200 sqft
Estimated Area Required (Actual) 4,800 sqft
Approximate Area Available 4,329 sqft
The current property's land available for the system is 4,329 sq.ft.,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 4,800 sq. ft., so there is not
sufficient space for this type of design at this 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 White Store soil. For a surface system in this soil,the SFR loading
rate group is likely restricted to a maximum annual loading of 15 in/year. The sizing calculation for a non-
discharge surface system is summarized in the table below:
Non-Discharge Surface Design Alternative
#Bedrooms 3
Daily Flow 360 gpd =120 gpd:#bedrooms
Surface Loading Rate 15 in/year
Minimum Area Required (Nominal) 14,053 sqft
Approximate Area Available 3,336 sqft
The current property's land available for a surface drip or spray system is 3,336 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 14,053 sq. ft., so there is insufficient space at this residence. The potential
waving of property setbacks was taken into account when considering the available application area for both
surface systems.
2. Assess the availability of land. If insufficient land is available onsite, assume that the necessary
land can be purchased and estimate the land purchase cost based on local real estate prices.
Alternatively,provide documentation to demonstrate that insufficient land is available for sale in
the project area (include letters from adjacent property owners indicating no interest in selling
property).
Response: Because insufficient land is available onsite, offsite land was reviewed. The table below lists neighboring
properties and the value of the land as listed by the Durham County GIS website. The values listed in the
table do not reflect the value of the single-family residences. The soil type listed for these properties is
White Store. These sites will be very restrictive for wastewater systems.

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)
Note:The proposed discharge system does not consider the pump tank,headworks box or disposal field.
Site drawings of these alternative systems showing the available application area are included as Appendix A
of the EAA. Due to the size requirements of a drip or spray system and the limited available space,there is no
ability to consider any of these systems on this property.
4. Explain the proposed reuse plan if reclaimed water will be used by a third party.
Response: There is no reuse plan being considered either on-site or by a third party. The existing residential plumbing
infrastructure does not allow for reuse in the existing residence. It is not feasible to consider using reclaimed
water on the site or becoming a bulk distributor of reclaimed water. The table below summarizes the amount
of reclaimed water that could be beneficially used on site. As shown, there is insufficient area to utilize the
daily flow of reclaimed water.
On-site Utilization of Reclaimed Water
Daily flow through system 360 gpd
Available Area to Irrigate 5,558 sqft *Veg.cover on property
Application Rate 0.5 in/week *Fescue Grass
Acceptable Volume to Irrigate 232 ft3/week
247 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.

P
6. Provide all calculations, documentation and maps as necessary to support assumptions and
conclusions.
Response: Calculations performed to evaluate land application alternatives are shown above in Alternative B,Points 1
and 4.
7. Note:The design of land application systems must meet the treatment and design requirements
specified in 15A NCAC 2T.0500 or 15A NCAC 18A.1900.
Response: The treatment systems specified above in Step B would meet the treatment standards required by these rules
as they pertain to single family residences. However, because of the lack of available space and other
restrictions listed above,no land-based systems can be considered.
8. Note: Proposed discharges from groundwater remediation systems must evaluate the potential
for an infiltration gallery treatment alternative.
Response: N/A
Alternative C. Wastewater Reuse.
You must evaluate reusing all or a portion of the wastewater generated. Some municipalities are currently
reusing wastewater within the confines of their WWTP property for irrigation, toilet flushing, backwashing,
etc., while other municipalities have established progressive reuse programs for residential irrigation.
Reuse applications might include golf course irrigation, crop irrigation (e.g., hardwood or pine plantation,
grasses), athletic field irrigation, landscape uses, and commercial/industrial uses. Some of these reuse
applications will be evaluated under Alternative B, Land Application. The design of reclaimed water
systems must meet the treatment and design requirements specified in 15A NCAC 2U.
Response: All reuse applications for this project scale were evaluated under Alternative B,Point 4. Wastewater reuse
was determined to be infeasible for this project.
Alternative D. Direct Discharge to Surface Waters.
1. No new or expanding (additional) discharge of oxygen-consuming waste will be allowed to
surface waters of North Carolina if both the summer 7Q10 and 30Q2 streamflows are estimated
to be zero,in accordance with 15A NCAC 2B.0206(d). Private applicants must contact the USGS
in Raleigh at 919-571-4000 and obtain (generally for a nominal fee), the receiving streamflow
data (s7Q10, 30Q2, annual average streamflow) at the proposed discharge location. This
information must be included in the EAA,and will be used to develop permit limits.
Response: Because this is an existing treatment facility with estimated zero flow at the discharge point and no expansion
in discharge proposed,the discharge will be considered on a case-by-case basis.
2. All direct discharge systems of oxygen-consuming wastes should be evaluated both with tertiary
filtration [BOD5= 5 mg/1, NH3-N= 1 mg/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/l. 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.
EAA Guidance Document Revision:April 2014
Page 6 of 8

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: A flow schematic is included as Attachment I(of application package).
4. Provide documentation of the availability of required land and/or easement agreements.
Response: The proposed discharge system will be located on land owned by the applicant,but an easement agreement
will be required to access the roadside ditch where the system will discharge. The land that must be crossed
is owned by a relative.
5. Conduct a Present Value Cost Analysis per STEP 4.
Response: A Present Value Cost Analysis for the discharge system is included in Appendix B. A summary of the
analysis is included in STEP 4.
6. Note: All direct discharge treatment systems must comply with Reliability Requirements
specified in 15A NCAC 2H.0124.
Response: The system serves a private facility that is served by a well and does not have elevated water storage tanks.
In the event of a power outage,water will not be available to the residence. There is storage available in the
system to hold some waste from the house until power is restored to the system. If excessive amounts of
wastewater are generated,the wastewater will back up in the house.
Alternative E. Combination of Alternatives.
You should evaluate the possibility of a combination of wastewater alternatives that would minimize or
eliminate a direct discharge alternative. For example, consider whether the facility can operate a land
application system during the dry season when streamflows are at their lowest and provide less dilution,
and operate an NPDES discharge system during the wet season when soils may not be as amenable to land
application and the receiving stream provides its greatest dilution.
Response: A non-discharge alternative is not feasible due to the space and soil constraints listed in Alternative B. The
presence or absence of a seasonal high water table will not relieve the other constraints.
EAA Guidance Document Revision:April 2014
Page 7 of 8

STEP 4. Evaluate economic feasibility of alternatives
PVCA Summary Table.
The EAA must include a Summary Cost Table, which summarizes present worth costs developed for all
technologically feasible wastewater alternatives. The summary should include a breakdown of capital costs
and recurring costs. In some situations, the Division may require the applicant to refine cost estimates for
some alternatives, or possibly collect actual soil data to better characterize the land application alternative.
Ultimately, the final determination on cost effectiveness is made by the Division with consideration of
monetary costs as well as potential environmental impacts.
Response: The following table presents the cost analysis for several types of wastewater systems. Given the information
presented above,the only technologically feasible alternative is the Discharge System. The"Install Cost"
includes the estimated cost to design and install the specific type of system. The"Present Value of Costs"is
based on a discount factor of 1.2%.

RE: Local Government Review Form
Application for Discharge System—Hunt Residence
3007 Redwood Road,Durham,NC 27704
Dear Mr. Bonfield
Enclosed please find a Local Government Review Form required for a Certificate of
Coverage application supporting a proposed wastewater treatment system. The proposed
system will be permitted under the NCG550000 General Discharge Permit for Single Family
Residences. The proposed system will serve an existing 3-Bedroom Single Family residence
(SFR) located in Durham County, North Carolina. The proposed system will replace the
unpermitted discharge system that currently serves the residence.
NC DEQ has issued many Pump and Haul permits for the property. That indicates that the
sand filter system that is currently at the property is under performing. It is my opinion that a
wastewater treatment system covered by the General Discharge is the only technology and
economical feasible option for this residence.
Will you please complete the enclosed form for inclusion in the application for the proposed
system. This residence is located in Durham County and is located in the Durham City limits.
Please note that this form is only meant to determine zoning/jurisdiction information, 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 919-859-0669.
Best Regards,
Kevin Davidson,P.E.
