RE: Application for Certificate of Coverage and Authorization to Construct
Discharge System—Oakes Residence
2117 Shaw Road, Durham,NC 27704
Dear Mr. Weaver,
Enclosed please find information supporting an application for a Certificate of Coverage and an
Authorization to Construct to serve an existing discharge system for a 3-Bedroom Single-Family
Residence (SFR) located in Durham County, North Carolina. The existing sand filter system
appears to be satisfactory and will be maintained. A new UV basin and pump chamber is being
proposed to satisfy the disinfection requirement. The site has been deemed unsuitable for ground
absorption sewage treatment systems by the Durham County Department of Environmental
Services due to unsuitable soil conditions and insufficient space.
The system is sized for 3 bedrooms (360 gallons per day) and has been designed to convey all
wastewater from the SFR, including greywater, to the septic tank. The site's existing septic tank
will be maintained unless it does not pass a leak test. In the event the tank doesn't pass the leak
test, it will be abandoned and replaced. This application is being submitted with the intent to
have coverage under the NCG55 General Permit. Coverage under this permit is sought to
maintain the existing sand filter and to include disinfection.

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.
2 of 71

Connection to a Regional or Municipal Sewer Collection System
Connection to a sewer collection system will likely not be available as per
correspondence with a representative from the City of Durham (Amber Andrews). Per
our own investigation, we believe that the nearest sewer to the property is well over 1
mile away. It is estimated that costs would exceed $250,00 to extend sewer to this
property(Attachment H).
Letter from the local or county health department describing the suitability or non-
suitability of the site for all types of wastewater ground adsorption and innovative
non-discharge systems. Document the repair potential of the failed system.
The Durham County Health Department indicated that the site is unsuitable for
installation of a ground absorption septic system in letter dated March 29, 2022.
(Attachment B). The letter indicated that an improvement permit cannot be issued due to
unsuitable soils.
Investigate Land Application such as spray irrigation or drip irrigation.
Per the soil evaluation by Jeff Vaughan, L.S.S. of Agri-Waste Technology, Inc., the site
does not have adequate space and suitable soil to accommodate a non-discharge surface
spray or drip wastewater system (Attachment E). The report indicated that this site is a
candidate for coverage under the NCG550000 permit.
7Q10 Flow Estimate
The United States Geological Survey (USGS) was contacted to determine the 7Q10 and
30Q2 flow estimates for the proposed wastewater discharge point. The proposed
discharge point is an existing flow path leading to an un-named tributary of Falls Lake.
The analysis from USGS indicates the 7Q10 discharge and the 30Q2 for the point in
question are zero. (Attachment F).
Engineering Alternatives Analysis
An Engineering Alternatives Analysis (EAA) has been completed for this site and is
included as Attachment H. 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(at the present time).
b.) subsurface disposal
- Inadequate soil for a subsurface absorption system.
c.) single-family residence wastewater irrigation (drip and spray)
- Inadequate soil and not feasible due to fill soil costs for a
non-discharge ground absorption system.
d.) reclaimed-water systems
- Inadequate soil and not feasible due to fill soil costs for a
reclaimed water system. No reasonable ability to operate
as a bulk distributor of reclaimed water.
e.) Any viable combination of the above
3 of 71

- 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 UV system are included as Attachment J.
I appreciate your time and efforts in reviewing this application. If you have any
questions or comments,please feel free to contact me at 919-859-0669.

Re: Application for Construction Authorization for Christie Cheek
Property site: 2117 Shaw Rd, Durham, NC 27703
Environmental Health Division file number:372786
Dear Christie Cheek
The Durham County Department of Public Health, Environmental Health Division on evaluated
the above referenced property at the site designated on the plat/site plan that accompanied your
construction authorization application. According to your application the site is to serve a 3
bedroom residence with a design wastewater flow of 360 gallons per day. The evaluation was
done in accordance with the laws and rules governing wastewater systems in North Carolina
General Statute 130A-333 including related statutes and Title 15A, Subchapter 18A, of the North
Carolina Administrative Code, Rule .1900 and related rules.
Based on the criteria set out in Title 15A, Subchapter 18A, of the North Carolina Administrative
Code, Rule .1940 through .1948, the evaluation indicated that the site is UNSUITABLE for a
sanitary system of sewage treatment and disposal. Therefore, we must deny your request for an
construction authorization. A copy of the site evaluation is enclosed. The site is unsuitable
based on the following:
Unsuitable soil topography and/or landscape position (Rule .1940)
✓ Unsuitable soil characteristics (structure or clay mineralogy) (Rule .1941)
✓ Unsuitable soil wetness condition (Rule .1942)
Unsuitable soil depth (Rule .1943)
Presence of restrictive horizon (Rule .1944)
Insufficient space for septic system and repair area (Rule .1945)
Unsuitable for meeting required setbacks (Rule _1950)
Other (Rule .1946)
These severe soil or site limitations could cause premature system failure, leading to the
discharge of untreated sewage on the ground surface, into surface waters, directly to ground
water or inside your structure.
The site evaluation included consideration of possible site modifications, as well as use of
modified, innovative, or alternative systems. However, the Health Department has determined
that none of the above options will overcome the severe conditions on this site. A possible
option might be a system designed to dispose of sewage to another area of suitable soil or off-
site to additional property.
For the reasons set out above, the property is currently classified UNSUITABLE, and no
construction authorization shall be issued for this site in accordance with Rule .1948(c).

Note that a site classified as UNSUITABLE may be classified as PROVISIONALLY SUITABLE if
written documentation is provided that meets the requirements of Rule .1948(d). A copy of this
rule is enclosed. You may hire a consultant to assist you if you wish to try to develop a plan
under which your site could be reclassified as PROVISIONALLY SUITABLE.
You have a right to an informal review of this decision. You may request an informal review by
the soil scientist or environmental health supervisor at the local health department. You may
also request an informal review by the North Carolina Department of Health and Human
Services regional soil scientist. A request for informal review must be made in writing to the
local health department.
You also have a right to a formal appeal of this decision. To pursue a formal appeal, you must
file a petition for a contested case hearing with the Office of Administrative Hearings, 1711 new
Hope Church Rd, Raleigh, NC 27609. To get a copy of a petition form, you may write the Office
of Administrative Hearings or call the office at [phone] or download it from the OAH web
site at http://www.oah.nc.gov. The petition for a contested case hearing must be filed in
accordance with the provision of North Carolina General Statutes 130A-24 and 150E-23 and all
other applicable provisions of Chapter 150B. N.C. General Statute 130A-335 (g) provides that
your hearing would be held in the county where your property is located.
Please note: If you wish to pursue a formal appeal, you must file the petition form with the
Office of Administrative Hearings WITHIN 30 DAYS OF THE DATE OF THIS LETTER. The
date of this letter is 3/29/2022 . Meeting the 30 day deadline is critical to your
formal appeal.
If you file a petition for a contested case hearing with the Office of Administrative Hearings, you
are required by law (N.C. General Statute 150B-23) to serve a copy of your petition on the
Office of General Counsel, N.C. Department of Health and Human Services, 2001 Mail Service
Center, Raleigh, N.C. 27699-2001.

15A NCAC 18A.1948 SITE CLASSIFICATION
(a)Sites classified as SUITABLE may be utilized for a ground absorption sewage treatment and disposal system
consistent with these Rules.A suitable classification generally indicates soil and site conditions favorable for the
operation of a ground absorption sewage treatment and disposal system or have slight limitations that are readily
overcome by proper design and installation.
(b)Sites classified as PROVISIONALLY SUITABLE may be utilized for a ground absorption sewage treatment and
disposal system consistent with these Rules but have moderate limitations. Sites classified Provisionally Suitable
require some modifications and careful planning,design,and installation in order for a ground absorption sewage
treatment and disposal system to function satisfactorily.
(c)Sites classified UNSUITABLE have severe limitations for the installation and use of a properly functioning ground
absorption sewage treatment and disposal system.An improvement permit shall not be issued for a site which is
classified as UNSUITABLE.However,where a site is UNSUITABLE,it may be reclassified PROVISIONALLY
SUITABLE if a special investigation indicates that a modified or alternative system can be installed in accordance with
Rules.1956 or.1957 of this Section.
(d)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 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.
The State shall review the substantiating data if requested by the local health department.

MEMORANDUM
TO: Mr. Colby Oakes
FROM: Jeff Vaughan, Ph.D.,LSS
SUBJECT: Site Evaluation for 2117 Shaw Road,Durham,NC 27704
(Durham County)
Agri-Waste Technology, Inc. (AWT) was contracted to perform a soils evaluation for the
purposes of on-site wastewater system suitability at the subject property in Durham, NC. The
evaluation was performed by Jeff Vaughan of AWT on May 4, 2023. An existing Single-family
residence with a buried discharging sand filter system is present on the subject property. The
property has been deemed unsuitable for subsurface wastewater systems by the Durham County
Environmental Health Department(Denial Letter dated 3/29/2022).
The soils currently on the property closely resemble the White Store soil series. The majority of
the property is unsuitable for septic systems due to unsuitable soil characteristics, unsuitable soil
wetness conditions, and unsuitable soil depths. There are also well setbacks to consider on the
subject property. Four holes were bored on the property and the soil examined. The soil
examination indicated that the soil was unsuitable for conventional, low-pressure pipe, and
subsurface drip septic systems due to the presence of the seasonal high-water table (SHWT) and
massive clay minerology within 12 inches of the soil surface.
The soils on the subject properties are unsuitable for subsurface and surface application
wastewater systems due to shallow wetness conditions, shallow depth to expansive clay
mineralogy, and insufficient space. Therefore, these properties do 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. This site is a candidate for
a NCG550000 General Permit surface water discharge systems.
Please contact us with any questions,concerns, or comments.

Ms. Davidson,
In response to your inquiry about the 7Q10 low-flow characteristic for an unnamed tributary to Little Lick
Creek adjacent the intersection of Shaw Road (NC SecondaryRoad 2501) and Sweetbriar Road (NC Secondary
Road 1897) in the 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
(36.02434, -78.76195) provided via email dated 05/03/2022 from the DWR USGS Low Flows 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 36.02436, -78.76196 NAD83) is 0.0535 sqmi, which confirms the drainage area submitted as part
of the request information.
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 statewide report completed in the early 1990's. It is USGS Water-Supply Paper 2403, "Low-
flow characteristics of streams in North Carolina" (Giese and Mason, 1993). An online version of the report is
available at http://pubs.usgs.gov/wsp/2403/report.pdf. The report provides the low-flow characteristics
(based on data through 1988) via regional relations and at-site values for sites with drainage basins between 1
and 400 sqmi and not considered or known to be affected by regulation and/or diversions.
(2)The second 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.
(3)The third is a statewide report initially published in March 2015 but revised and republished (as version
1.1) in March 2016. 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, 2016). 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 little more than 0.05 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 drainage
areas that would typically be expected to have sustained flows actually have some of the lowest low-flow
estimates in the state.
Consideration of the above information results in a conclusion the 7Q10 discharge for the point of interest is
zero flow.
Please understand the information provided in this message is based on a preliminary assessment and
considered provisional, subject to revision pending further analyses.
This low-flow response is provided via the DWR USGS Low Flows cooperative agreement between the USGS
and the N.C. Department of Environmental Quality, Division of Water Resources.
Hope this information is helpful.
Thank you.

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 discharge point is a ditch that is on the
applicant's property leading to an un-named tributary of Falls Lake.. The analysis from USGS indicates the 7Q10
discharge for the point in question is 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: An existing wastewater discharge system is to be maintained and upgraded for the existing 3-Bedroom Single
Family Residence (SFR) located in Durham County, North Carolina. The proposed upgrade to the system will
add disinfection to the system that currently serves the residence. The discharge point is a ditch that is on the
applicant's property. The existing treatment system with upgrade will utilize the following components:
Septic Tank with Effluent Filter(existing tank to be replaced if it doesn't pass a leak test)
Existing buried single pass sand filter
Pump Chamber(new)
UV Disinfection(new)
Discharge Point with Rip-Rap
Construction of the system upgrade 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 clearlyjustified. If population projections include future
P P
annexations, include a proposed annexation schedule as well as any annexation requirements that must be
met.
Response: Because the wastewater treatment system is serving 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. Amber Andrews,Engineering Technician
for the City of Durham,indicated that sewer is not currently available for the applicant's property. We are not
aware of any plans to extend the sewer.A sewer extension to this property would require the property to be
EAA Guidance Document Revision:April 2014
Page 2 of 8
46 of 71

annexed by the City of Durham into the City Limits and funding the expansion would be the responsibility of the
property owner. The closest sewer system is located well over a mile from the property(Attachment H).For
reference, if an installation cost of$100/ft of installed sewer line was assumed,the cost to connect this property to
the sewer line would exceed$500,000.
(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,there are no known plans to extend the sewer.
Alternative B. Land Application.
Land application disposal alternatives include individual/community onsite subsurface systems, drip
irrigation,and spray irrigation.
1. Provide an estimate of the best case hydraulic loading rate based on County Soil Surveys or from
a soil evaluation performed by a soil scientist. Include calculations showing the hydraulic
loading rate and the total area of land needed for the land disposal system,including buffers.
Response: The Durham County Department of Public Health indicated that the site is unsuitable for installation of a ground
absorption septic system in a letter dated March 3, 2022 (Attachment B of application package). The letter
indicated that a permit cannot be issued due to unsuitable soil characteristics, unsuitable soil wetness and
unsuitable soil depth.
Per the soil evaluation by Jeff Vaughan of Agri-Waste Technology, Inc., the site does not have suitable soil to
accommodate a ground absorption or surface drip or surface spray wastewater system (Attachment E of
application package).
Regardless of the fact that a subsurface ground absorption cannot be designed or permitted for this site, the
potential size of a subsurface system has been estimated. According to the county soil survey, the site is
classified as a White Store soil series. This soil would be 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:
EAA Guidance Document Revision:April 2014
Page 3 of 8
47 of 71

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/STAR
Estimation for Topographical Variation 1,200 sqft
Estimated Area Required (Actual) 4,800 sqft
Approximate Area Available 58,327 sqft
The current property's land available for the system is over an acre after considering setbacks and existing site
conditions. The land needed for a subsurface dripfield design is a minimum of 4,800 sq. ft., so there is
sufficient space for this type of system at the residence except that the soils are not suitable for a system.
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 series soil. For a surface system in this soil,the SFR
loading rate group is likely restricted to a maximum annual loading of 19.5 in/year. The sizing calculation for
a non-discharge surface system is summarized in the table below:
Non-Discharge Surface Design Alternative
# Bedrooms 3
Daily Flow 360 gpd =120 gpd•#bedrooms
Surface Loading Rate 19.5 in/year
Minimum Area Required (Nominal) 10,810 sqft
Approximate Area Available 8,104 sqft
The current property's land available for a surface drip or spray system is approximately 8,104 sqft, due to
setbacks and existing site conditions. The major limiting factors that prevent this type of system are the 100'
well setback, the 50' property setback, and the location of the SFR as well as the 15' foundation setback. The
land needed for a non-discharge application system is estimated at 10,810 sq.ft.,so there is insufficient space for
this type of system at the residence.
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 inadequate space), 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 types listed for the properties is White Store(WsB, WsC, WsE). These sites, like the applicant's site,
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)with addition of fill soil
Note:The proposed discharge system does not consider the pump tank,headworks box or disposal field.
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.
On-site Utilization of Reclaimed Water
Daily flow through system 360 gpd
Available Area to Irrigate 39,744 sqft *Veg.cover on property
Application Rate 0.5 in/week *Fescue Grass
Acceptable Volume to Irrigate 1656 ft3/week
= 1770 gpd
5. Conduct a Present Value Cost Analysis per STEP 4. For the reclaimed water system include the
YY
potential revenue generated by selling the water.
Response: A Present Value Cost Analysis is included as Appendix B of the EAA. An analysis was performed for a
sub-surface drip system, a non-discharge surface application system, and a reclaimed water system. A
summary of the analysis is included in STEP 4.
6. Provide all calculations, documentation and maps as necessary to support assumptions and
conclusions.
Response: Calculations performed to evaluate land application alternatives are shown above in Alternative B, Points 1
and 4.
7. Note:The design of land application systems must meet the treatment and design requirements
specified in 15A NCAC 2T .0500 or 15A NCAC 18A.1900.
EAA Guidance Document Revision:April 2014
Page 5 of 8
49 of 71

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/I, NH3-N= 1 mg/1] and without, and assuming a weekly sampling
regime.
Response: Tertiary filtration is not required under the general permit, as the general permit requirements (monthly
average)are BOD5=30 mg/I and Total Suspended Solids=30 mg/I. Sand filter systems can provide a high-
quality effluent. While weekly sampling of the treated effluent would confirm the treatment results on a
regular basis, the additional cost associated with the collection and testing of the effluent would not be
feasible for the homeowner.
3. Provide a description of the proposed wastewater treatment facilities, including a schematic
diagram of the major components and a site plan of the treatment facility with outfall line(s).
Response: Plans and schematic drawings can be found in Attachment K(of application package).
4. Provide documentation of the availability of required land and/or easement agreements.
Response: N/A
5. Conduct a Present Value Cost Analysis per STEP 4.
EAA Guidance Document Revision:April 2014
Page 6 of 8
50 of 71

Response: A Present Value Cost Analysis for the discharge system is included in Appendix A. 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 an on-site well and does not have elevated water storage
tanks. In the event of a power outage,water will not be available to the residence. There is storage available
in the system to hold some waste from the house until power is restored to the system.
Alternative E. Combination of Alternatives.
You should evaluate the possibility of a combination of wastewater alternatives that would minimize or
eliminate a direct discharge alternative. For example, consider whether the facility can operate a land
application system during the dry season when streamflows are at their lowest and provide less dilution,and
operate an NPDES discharge system during the wet season when soils may not be as amenable to land
application and the receiving stream provides its greatest dilution.
Response: A non-discharge alternative is not feasible due to the space and soil constraints listed in Alternative B. The
presence or absence of a seasonal high water table will not relieve the other constraints.
EAA Guidance Document Revision:April 2014
Page 7 of 8
51 of 71

STEP 4. Evaluate economic feasibility of alternatives
To provide valid cost comparisons among all technologically feasible wastewater alternatives identified in
STEP 3, a 20-year Present Value of Costs Analysis (PVCA) must be performed. A preliminary design level
effort is considered appropriate for comparing feasible options and their associated costs. For the PVCA cost
comparison, all future expenditures are converted to a present value cost at the beginning of the 20-year
planning period. A discount rate is used in the analysis and represents the time value of money(the ability of
money to earn interest). Present value is also referred to as "present discounted value" or"present worth".
The PVCA should include all monetary costs associated with construction,startup and annual operation and
maintenance of a facility. All unit cost information must be provided, and costs must be referenced. Costs
can be referenced in paragraph format by summarizing the sources utilized (e.g.,vendor quotes,realtor land
quotes, past bids, Means Construction Index, etc). Vender quotes received for treatment units or other
components, as well as realtor land quotes, shall be included as well. For each treatment alternative
identified as technologically feasible,costs should include,but not be limited to,the following:
Capital Costs
• Land acquisition costs
• Equipment costs
• Labor costs
• Installation costs
• Design costs
Recurring Costs
• Operation and maintenance costs (with replacement costs)
• Laboratory costs assuming a weekly monitoring regime for discharge systems and a monthly
regime for non-discharge systems
• Operator and support staff costs
• Residual disposal costs
• Connection fees and subsequent user fees
• Permit and compliance fees
• Utility costs (power,water,etc.)
Lost Opportunity Costs
PVCA Calculation Method.
The following standard formula for computing the present value must be used in all cost estimates made
under this evaluation:
n Ct
Pv= c +t ,
,_, (1 +r)
Where:
PV = Present value of costs.
Co = Costs incurred in the present year.
Ct = Costs incurred in time t.
t = Time period after the present year(The present year is t= 0)
n = Ending year of the life of the facility.
r = Current EPA discount rate. EPA adjusts this rate annually on October 1, and it can be
accessed from the Internet at http:/www.nccgl.net/fap/cwsrf/201gui.html.
EAA Guidance Document Revision:April 2014
Page 8 of 8
52 of 71

If recurring costs are the same in years 1 through 20,then Ct=C and the formula reduces to:
PV= C +C (1 +Y)° —1l
_ Y(1+ Y)n J
As an example,assuming capital costs (Co) of$2 million,annual recurring costs (C)of$40,000,and a
discount rate (r)of 5.625%,the 20-year(n=20)present value of costs would equal:
PV= capital costs + recurring costs X [(1+0.05625)20—1] / [0.05625(1+0.05625)20]
PV= $2,000,000 + $40,000 X [1.98/0.168]
PV= $2,000,000 + $471,428
PV= $2,471,428
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 2.25%.

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:

RE: Local Government Review Form
Application for Discharge System—Oakes Property
2117 Shaw Road,Durham,NC 27704(Durham County PIN 0872-18-11-3930)
Dear Ms. Page,
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 (SFRs). The proposed system will serve an existing SFR located in
Durham County, North Carolina. The proposed system will replace a failed sand filter
system that currently serves the SFR.
The site has been deemed unsuitable for ground absorption sewage treatment systems by
the Durham County Department of Public Heath 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 Durham County. We acknowledge that the property
may not be located within the City of Durham limits. Please note that this form is only
meant to determine zoning/jurisdiction information for the county and does not indicate
your approval of the proposed system.
I appreciate your time and efforts in completing this form. If you have any questions or
comments,please feel free to contact me at 919-367-6310.
Best Regards,
Kevin Davidson,P.E.
