Permit NCG550598
Dear Mr. Charles Weaver,
lbl2r-.z3
Enclosed please find information supporting an application for a discharge system for a 3-
Bedroom Single Family Residence (SFR) located in Durham County, North Carolina. This is a
request for modification to an existing permit. The proposed system will incorporate a pump
chamber with UV treatment into an existing sand filter discharge system that serves the
residence. The site has previously been served by a common neighborhood trunk-line that has
malfunctioned. The proposed system is to be sized for 3 bedrooms and has been designed to
convey all wastewater from the SFR, including greywater, to the proposed septic tank.
The following information is included with this letter:
- Notice of Intent(NCG550000). AttachmentA
- $60 check payable to North Carolina DENR.
- Documentation from Durham County Department of Attachment B
Public Health.
Letter requesting Modified Coverage under the General Permit. Attachment C

The proposed discharge location is to a road-side ditch on the property that flows to an
unnamed tributary to Little River. The flow path has been included as part of this package
in Attachment G. The discharge system will utilize the following components:
Existing Septic Tank
New Orenco Effluent Filter
Existing Sand Filter
UV Disinfection
Discharge Point with Rip-Rap
Flow Path to "Blue Line"Water Feature
The proposed discharge location is to a road-side ditch on the property that flows
to an unnamed tributary to Little River. A map showing the path from the
discharge point to the first "blue-line" stream, as shown on the USGS Stream
Stats NC Map, can be seen in Attachment G. The latitudinal and longitudinal
information presented below is the approximate location of the confluence of the
unnamed tributary with Little River.
Receiving Stream Little River(Little River Reservoir)
Stream Index 27-2-21-(3.5)
Stream Class WS-II; HQW,NSW, CA
Latitude 36.133°
Longitude -78.871°
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. The City of
Durham Public Works Department indicated that the property is not within the city's
coverage area. The closest current-city maintained sewer is approximately 1.6 miles, or
8,448 linear ft, from the property. There are no immediate plans for sewer extension to
the area at this time. (Attachment H). At an estimate of $150/ft, the sewer extension
would cost over$1,267,200.

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.
A county denial is not required as this is a modification for an existing certificate of
coverage. Jane Bernard and Charles Weaver were contacted 7, 2023 regarding
ag February g g
the site and situation.
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 sufficient space or suitable soil characteristics to accommodate a non-
discharge surface spray or drip wastewater system (Attachment E).
7Q10 Flow Estimate
The United States Geological Survey (USGS) was contacted to determine the 7Q10 flow
estimate for the proposed wastewater discharge point. The proposed discharge point is to
an unnamed tributary to Little River. The analysis from USGS indicates the 7Q10
discharge for the point in question is likely zero (Attachment F).
Engineering Alternatives Analysis
An Engineering Alternatives Analysis (EAA) has been completed for this site and
is included as Attachment I. In my opinion, the completed EAA demonstrates
that a wastewater treatment system permitted under the NCG550000 General
Discharge Permit is the only feasible option for this site. We have exhausted all
other options for this site as follows:
a.) connection to a municipal or regional sewer collection system
- Not feasible due to costs.
b.) subsurface disposal
- Inadequate soil for a subsurface absorption system.
c.) single-family residence wastewater irrigation (drip and spray)
- Inadequate soil and insufficient space 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
- There are no viable combinations of the above due to soil
and cost limitations.

Local Government Review Forms
N/A — Local Government Review Forms are not required in this scenario as this is a
request for modification to an existing certificate of coverage.
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: Letter Requesting Coverage under the General Permit—Flores Residence
6919 Innesbrook Way, Bahama,NC 27303
Permit NCG550598
Dear Mr. Hennessy;
Please consider this letter as a request for modified coverage under the General Permit for
a Wastewater Treatment and Discharge. The proposed discharge system is for a 3-
Bedroom Single Family Residence (SFR) located in Durham County, North Carolina.
The proposed discharge system will incorporate a new pump chamber with UV treatment
into the existing sand filter discharge system and re-route the line to discharge. The site
has previously been served by a common neighborhood trunk-line that has
malfunctioned. This design proposes an individual discharge line and system. The
proposed system is to be sized for 3 bedrooms at 360 gallons/day. The residence is
located at 6919 Innesbrook Way, Bahama,NC 27503.
Thank you for your assistance in this matter.
Sincerely,

Soils Evaluation Summary
TO: Mr. Luis Flores (client)
FROM: Jeff Vaughan,NC LSS
SUBJECT: Soils Evaluation for 6919 Innesbrook Way, Bahama,NC (Durham County)
Agri-Waste Technology, Inc. (AWT)was contracted to perform a soils and site evaluation for
the purpose of on-site wastewater system suitability at the subject property in Bahama,NC. The
evaluation was performed by Jeff Vaughan of AWT. A single-family residence with an existing
malfunctioning sand filter discharge system is located on the property.
The soils on the subject properties are unsuitable for conventional and alternative subsurface
wastewater systems due to unavailable space and shallow depth to expansive clay and
redoximorphic features. Surface application/irrigation systems do not qualify for this lot due to
insufficient space based on required setbacks, slope, and depth to restrictive features limiting soil
water movement.
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 new surface water discharge
system.
Please contact us with any questions, concerns, or comments.

Engineering Alternatives Analysis (EAA) Guidance Document
North Carolina Division of Water Resources
STEP 1. Determine if the proposed discharge will be allowed
Before beginning any engineering evaluation of alternatives, you must first determine if the proposed
wastewater discharge will be allowed. Otherwise, time and money may be spent needlessly for an EAA
preparation that will ultimately be rejected on the basis of existing water quality restrictions. There are
several potential restrictions to a wastewater discharge to surface waters,including:
■ Zero flow stream restrictions [15A NCAC 2B.0206(d)(2)] apply to oxygen-consuming waste in
zero-flow streams. In order to determine streamflow at the proposed discharge location, contact
the U.S. Geological Survey at 919-571-4000.
• Receiving stream classification restrictions [e.g., ORW, WS, SA, NSW, and HQ class waters
have various discharge restrictions or require stricter treatment standards]. Stream
classifications are available on the the DWR Classification and Standards/Rule Review Branch
website: (http://portal.ncdenr.org/web/wq/ps/csu), while wastewater discharge restrictions
for various stream classifications are presented in state regulations [15A NCAC 2B.0200].
• Basinwide Water Quality Plans. These basin-specific plans list NPDES permitting strategies
that may limit wastewater discharges to particular streams within the basin due to lack of stream
assimilative capacity, etc. Basin plans are available on the DWR website,or you may contact the
DWR Basinwide Planning Branch (http://portal.ncdenr.org/web/wq/ps/bpu)..
• Impaired waters and TMDLs. Certain waterbodies listed as impaired on the 303(d) list and/or
subject to impending TMDLs may have wastewater discharge restrictions. The list of 303(d)
impaired waters is located on the DWR website, or you may contact the DWR Modeling and
Assessment Branch (http://portal.ncdenr.org/web/wq/ps/mtu).
• Presence of Endangered Species. If endangered species are present in the proposed discharge
location, there may be wastewater discharge restrictions. Endangered species information may
be included in the Basinwide Water Quality Plan, or you may contact the U.S. Fish and Wildlife
Service (919-856-4520),N.C. Wildlife Resources Commission (919-733-3633), or the N.C. Natural
Heritage Program (919-733-7701).
Municipal applicants.
As a public service, the NPDES Unit will evaluate whether a proposed municipal discharge is considered
allowable. The municipality needs to initiate this review by submitting a letter request for Speculative
Effluent Limits to the NPDES Unit. 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, 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 speculative limits request letter. If the proposed discharge appears to be allowable, the
NPDES Unit will prepare speculative effluent limits for a maximum of 2 flows and 2 discharge locations using
water quality models. The municipality can then use the speculative limits to prepare preliminary
engineering design and cost estimates for the direct discharge alternative within the EAA. In limited
instances where complex water quality models are necessary to develop speculative limits and determine
potential water quality impacts, some municipalities have undertaken the modeling effort (with DWR review)
in order to expedite this portion of the NPDES permit review process.
Response: N/A Non-municipal applicant
EAA Guidance Document Revision: October 2019
Page 1 of 12

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 and 30Q2 flow estimate for the
downstream tributary of the proposed wastewater discharge point. The proposed discharge location is to a road-
side ditch that leads to an unnamed tributary to Little River. The USGS analysis indicates the 7Q10 and 30Q2
flow characteristics are likely zero flow.The flow request is included in Attachment F of the 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 modify a failing sand filter discharge system that
currently serves the residence. The proposed discharge location is to a road-side ditch on the property that leads
to an unnamed tributary to Little River.The proposed treatment system will utilize the following components:
Existing Septic Tank with new Orenco Effluent Filter
- Existing Sand Filter
Pump Chamber
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.
Municipal Flow Projections.
Justification of flow as well as a demonstration of need shall be provided. Mere speculation is not sufficient.
Flow projections should represent average anticipated flows, since permit flow limits are based on monthly
averages. Peaking factors used to design various components of the wastewater collection system (e.g.,
collector sewers,interceptor sewers,pumping stations) should not be used in the justification of the average
anticipated flow. For municipal wastewater dischargers, flow must be justified using the Clean Water Loan
Program (CWLP) Guidance for Preparing Engineering Reports available on the Internet at
http://portal.ncdenr.org/web/wi/cleanwater/er. Exceptions to these flow criteria may be approved on a
case-by-case basis provided adequate justification is supplied.
• Current Flow- Provide current flows including residential, commercial, industrial, and
infiltration/inflow (I/I) based on actual flow data or water billing records. Current residential
flow and current commercial flow may be based on water billing records minus a 10%
consumptive loss. Current industrial flow may be based on dual metering to determine
consumptive losses.
• Future Residential Flow- Provide 20-year residential flows based on projected residential growth.
Multiply the projected growth in residential population by 70 gallons per day per capita.
• Future Commercial Flow- Provide 20-year commercial flows based on projected residential
growth. Multiply the projected growth in residential population by 15 gallons per day per capita.
EAA Guidance Document Revision: October 2019
Page 3 of 12

• Future Industrial Flow- Provide flow for future documented industrial flow. A nominal
allowance for future unplanned industrial expansions may be considered by the Division,
provided the basis is clearly justified and current land-use plans and local zoning allow for such
industrial growth.
Response: N/A Non-municipal applicant
Non-Municipal Flow Projections.
Flow may be justified in accordance with 15A NCAC 2H .0219(1) for various activities (e.g., new
subdivisions, new schools, various commercial activities). For other proposed discharges (e.g.,
groundwater remediation, water treatment plant filter backwash, industrial facilities), the flow projections
will be based on engineering design considerations and/or production projections rather than population
projections.
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
Since a goal of the Clean Water Act is to minimize or eliminate point source discharges to surface waters,
any proposal for a new or expanding wastewater discharge must include evaluation of wastewater disposal
alternatives in addition to direct discharge. Particularly for dischargers of domestic wastewater, this
evaluation should investigate the feasibility of the following wastewater disposal alternatives:
• Connection to an existing wastewater treatment plant(public or private)
• Land application alternatives, such as individual/community onsite subsurface systems, drip
irrigation,spray irrigation
• Wastewater reuse
• Surface water discharge through the NPDES program
• Combinations of the above
In order for the applicant to eliminate a wastewater disposal alternative, you must either show that the
alternative is technologically infeasible, or that it would be cost prohibitive to implement relative to a direct
discharge alternative. Please note that for some alternatives, it might be easier to prove an alternative is not
viable based on high cost rather than technological feasibility. For example,for a large municipal expansion
that would require several hundred acres for a land application alternative, it might be easier to simply
assume that the required acreage could be purchased and calculate the present value costs (including current
market land costs) for this option, rather than evaluating whether land application is technologically
infeasible due to lack of available land and/or poor soil conditions. For those alternatives identified as
technologically feasible,you must develop and compare costs, based on a preliminary level design effort (see
STEP 4).
The Division recognizes that wastewater disposal alternatives may be limited for some non-domestic
wastewater scenarios, and a full alternatives evaluation may not be warranted. If there is some question as to
whether an alternative may be eliminated, contact the NPDES Unit staff. Some scenarios that might not
require a full alternatives evaluation include:
• Water Treatment Plant Discharges. Discharges from water treatment plants (WTPs) that utilize
a membrane technology (e.g., reverse osmosis, nanofiltration) or ion exchange system tend to
generate highly concentrated wastestreams. These wastestreams are not amenable to land
application and do not have to be evaluated for this alternative. However, since these
EAA Guidance Document Revision:October 2019
Page 4 of 12

wastestreams can also have a toxic impact on a receiving freshwater system, proposed new
discharges from these WTPs to freshwaters will not be considered for an NPDES permit unless
you can demonstrate that the environmental impacts would be minimal based on dilution
modeling. You should investigate whether the wastewater can be piped to a stream with
sufficient dilution, or whether a local WWTP might accommodate this discharge. Please note
that discharges from WTPs that utilize greensand filtration or conventional technology produce
a wastestream that is not saline,therefore no disposal alternatives can be automatically ruled out
as infeasible for these other WTPs. Refer to the NPDES website for permitting strategies for
reverse osmosis,ion exchange,greensand filtration,and conventional WTPs.
• Groundwater Remediation System Discharges. You will need to evaluate whether WWTP
connection, land application, infiltration galleries, in-situ groundwater remediation wells, or
closed-loop groundwater remediation wells are viable disposal alternatives. While land
application might be a feasible alternative in rural areas, it would not be a feasible alternative in
downtown Charlotte, where there is no land available for wastewater application. In this
instance, you may simply state that land application is infeasible based on land constraints
within the city. You will also need to evaluate connection to an existing WWTP (in accordance
with Alternative A), since there are some municipalities that have accepted this waste stream in
the past. If the municipality will not accept the waste stream, the connection alternative is also
considered technologically infeasible. Please note that in-situ and closed-loop groundwater
remediation wells are permittable well types and further guidance is available through the
Aquifer Protection Section.
Aside from these exceptions,you should proceed with the alternatives evaluation in accordance with the
following requirements. If you have any questions about these requirements,contact the NPDES Unit staff.
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 residence. The city of Durham Public Works
Department indicated that the property is not within the city's coverage area. The closest current-city maintained
sewer is approximately 1.6 miles, or 8,448 linear ft, from the property and is across Little River in Treyburn.
There are no immediate plans for sewer extension to the area at this time. (Attachment H). at an estimate of
$150/ft,the sewer extension would cost over$1,267,200.
(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
EAA Guidance Document Revision: October 2019
Page 5 of 12

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 property is not able to access city sewerage.
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 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 due to unsuitable
topography and shallow depth to expansive clay and redoximorphic features. Surface application/irrigation
systems do not qualify for this lot due to insufficient space based on required setbacks, slope, and depth to
restrictive features limiting soil water movement. (Appendix E of package).
Regardless of the fact that a subsurface ground absorption system cannot be designed or permitted for this site,
the potential size of a subsurface system has been estimated in the table below.
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 3,565 sqft
The current property's land available for the sub-surface system is 3,565 sq.ft. with 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,and the soils are unsuitable for supporting this type of system.
EAA Guidance Document Revision: October 2019
Page 6 of 12

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 0 sqft
The current property's land has no available space for the system. A schematic of this area is shown in
Appendix A. The land needed for a non-discharge application system is estimated at 10,810 sq. ft.. There is not
sufficient space for a non-discharge surface system and the unsuitable soil conditions on the property do not
allow for a non-discharge system.
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: Insufficient land is available for sale in the project area. The table below lists neighboring properties and the
value of the land as listed by the Durham County GIS website. The surrounding lots contain occupied
single-family residences. The values listed in the table do not reflect the value of the single-family
residences.

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
-AdvanTex Treatment Pod
-Pump Tank
-UV Disinfection
-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 limitations caused by the soil characteristics and conditions, 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 may be sufficient area to
utilize the daily flow of reclaimed water, however; a reclaimed system would be cost prohibitive for a
single-family residence.
On-site Utilization of Reclaimed Water
Daily flow through system 360 gpd
Available Area to Irrigate 7,992 sqft *Veg.cover on property
Application Rate 0.5 in/week *Fescue Grass
Acceptable Volume to Irrigate 333 ft3/week
356 gpd
5. Conduct a Present Value Cost Analysis per STEP 4. For the reclaimed water system include the
potential revenue generated by selling the water.
Response: A Present Value Cost Analysis is included as Appendix B of the EAA. An analysis was performed for a
sub-surface drip system, a non-discharge surface application system, and a reclaimed water system. A
summary of the analysis is included in STEP 4.
6. Provide all calculations, documentation, and maps as necessary to support assumptions and
conclusions.
Response: Calculations performed to evaluate land application alternatives are shown in Alternative B.
7. Note:The design of land application systems must meet the treatment and design requirements
specified in 15A NCAC 2T .05 or 15A NCAC 18A.1900.
EAA Guidance Document Revision:October 2019
Page 8 of 12

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 due to
unsuitable soil conditions,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, Step 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: With an estimated zero flow at the discharge point,the discharge will be considered on a case-by-case basis.
The proposed discharge is 360 gpd.
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/1 can be met. While weekly sampling of the treated effluent would confirm the
treatment results on a regular basis, the additional cost associated with the collection and testing of the
effluent would not be feasible for the homeowner.
3. Provide a description of the proposed wastewater treatment facilities, including a schematic
diagram of the major components and a site plan of the treatment facility with outfall line(s).
Response: Plans and schematic drawings can be found in Attachment K(of application package).
4. Provide documentation of the availability of required land and/or easement agreements.
EAA Guidance Document Revision: October 2019
Page 9 of 12

Response: The proposed discharge system discharges directly to a drainage ditch on the client's property. See
attachment G for the discharge system flow path.
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 ISA NCAC 2H.0124.
Response: The system serves aprivate facilitythat is served byaprivate well and does not have elevated water storage
P Y �
tanks. In the event of a power outage,water will 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 the power is out for
an extended period,ceasing water usage in the house or pumping of the septic tank may be required.
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 soil constraints listed in Alternative B. The presence or
absence of a seasonal high-water table will not relieve the other constraints.
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
EAA Guidance Document Revision:October 2019
Page 10 of 12

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:
PV= C
(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.
If recurring costs are the same in years 1 through 20,then Ct=C and the formula reduces to:
n
PV= C +C (1 +r) �1
_ r(1+ r) 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 11.98/0.168]
PV= $2,000,000 + $471,428
PV= $2,471,428
EAA Guidance Document Revision: October 2019
Page 11 of 12

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%.

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.

Narrative Description
of
Discharge Treatment System
The Discharge System that has been designed considers the following components:
- Existing Septic Tank
- Existing Sand Filter
- Pump Chamber
- 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
The system design utilizes the existing septic tank on the property.A leak test will be performed,and
24"single piece Orenco risers will be installed on the inlet and outlet of the septic tank.An Orenco
8"Biotube effluent filter will also be installed in the outlet of the septic tank. If the existing septic
tank is not used, or if it fails the leak test, the project engineer will be contacted. To facilitate the
installation of the access risers,riser adapters will be cast into the tank top during construction. All
wastewater from the single-family residence,including greywater,will be routed into the septic tank.
Waste that exits the septic tank will flow into the existing sand filter on the property.
Pump Chamber
Effluent from the sand filter will drain into the inlet of the pump chamber and be treated with an
Orenco UV Disinfection Unit. The treated effluent will be pumped from the pump chamber to the
discharge point. A 24" Orenco riser will be installed 6"above the ground surface.
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 to a road-side ditch on the property that flows to an unnamed tributary to
Little River. Riprap will be placed at the discharge location to provide aeration of the water as it is
discharged,and it will also act 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.
1

Control Panel
Two individual control panels will be installed with this wastewater system. One panel will control
the operation of the UV system and the other will control the operation of the discharge pump. If
desired,a control panel can be connected to a land-based phone line that will notify the operator of
system operation.The control panels will be mounted side by side at a minimum of 24"above grade.

Access Risers and Tank Adapters
o
800-348-9843
Installation Instructions
Access risers provide access to septic tank openings,simplifying inspection and maintenance procedures. It is important
that the riser be sized correctly and installed properly(i.e.,appropriate tank adapter,attachment method,etc.)to ensure a
watertight seal.Without a watertight seal,groundwater or surface water can leak into the tank, reducing the tank's perfor-
mance.When setting a riser,orient the grommets in the appropriate directions before bonding to the tank.
In this document,metric equivalents are omitted for nominal dimensions,such as riser and pipe diameters. If you are using
pipe other than IPS standard sizes, consult your Distributor for adapters you may need.
Riser Sizing
The installed riser should extend about 3 in.(76 mm)above the finished ground level(approximately 2 in. [51 mm]for tank
settlement and 1 in. [25 mm]to ensure drainage away from the riser). If the riser is too long,it may be cut to the appropri-
ate height using a circular saw or table saw.Always cut excess length from the bottom of the riser.To ensure a good fit and
watertight joint,a square cut is essential. If the riser is too short, a grade ring may be used as an extension.
Selecting a Riser and Tank Adapter Installation Method
To select an appropriate riser and tank adapter installation method,first determine the type of tank being used: concrete or
fiberglass.Then refer to the chart below,as you follow these steps:
Concrete Tanks
1. Determine desired riser diameter.
2. Determine if the riser tank adapter will be cast-in or bolted down.
3. Referring to the chart below,pick the appropriate tank adapter for your riser diameter and method of attachment.
If the bolt-down method is being used,make sure the adapter you selected will cover the tank's opening.
Orenco Fiberglass Tanks(contact your distributor or Orenco for other fiberglass tanks)
1. For 30-in. riser, choose the FRTA30-FRP tank adapter.
2. For 24-in. riser,no adapter is needed;24-in. riser fits tank directly.

About Adhesives
ADH100 is a single-component adhesive/sealant for sealing pipe grom-
_ mets and joining PVC or fiberglass risers to ABS or fiberglass PRTA-
�— -� aim" style tank adapters(where the joint is in shear). Handling strength is
f2 s a achieved within 12 hours,and full cure in 2 to 3 days. It comes in a
t 55115
- I 10.2-oz(300-mL) cartridge tube for application with a caulking gun.
ADH10 IIPS810)adhesive is a white,two-component,self-leveling
methacrylate adhesive for bonding PVC,ABS,fiberglass, and concrete.
ADH10 comes in pint(500-mL)and quart(1000-mL)kits, consisting of
A and B components(adhesive and activator), and requires hand mix
ing. If a self-leveling adhesive is NOT required or if concrete is NOT
being bonded,SS115 or SS140 is preferred over ADH10.
ADH845 adhesive is a tan two-component methacrylate adhesive for
Clockwise from left:ADH10/IPS810)quart, SS115, bonding PVC,ABS,fiberglass, and concrete.This is our only adhesive
MA320 SS140,ADH845,ADH10/IPS810/pint, and formulated to work in wet conditions or even under water, making it
ideal for field repairs. Repairs on leaking riser connections are pos-
sible, but any water pressure must be removed during the repair.
ADH845 has the consistency of molasses, comes in 400-mL cartridges,
and requires the manual dispensing gun ADH845-GUN.
MA320 is a white two-component methacrylate adhesive that bonds
PVC,ABS and fiberglass to themselves or each other, but does not
bond to concrete. It comes in a two-part 200-gram see-through plastic
pouch that must be kneaded to mix the two components,then cut open
and squeezed to apply adhesive.
SS140 adhesive is a gray two-component methacrylate adhesive for
bonding PVC and fiberglass to themselves or each other. It does not
bond to concrete. It has the consistency of toothpaste and will sag
slightly in warmer temperatures.Surface roughening is recommended
and provides the best bond strengths, but is not always necessary. Use
SS140 above 65° F(18° C)and SS115 below 50° F(10° C).Working life
of mixed adhesive is typically 20 to 30 minutes, and it usually hardens
in less than 2 hours,depending on temperature and adhesive thick-
ness. It comes in an 870-mL two-part cartridge and can be dispensed
from pneumatic gun SS-MK or,for occasional use,manual gun SS-MK-
MANUAL GUN.
SS115 adhesive is a white two-component methacrylate adhesive with
properties similar to those of SS140 and comes in the same two-part
cartridge,but has a much shorter open time for use in cooler tempera-
tures and jobs where quicker cure times are desired, or for applica-
tions where a white color is desired.Working life of mixed adhesive is
typically 10 to 15 minutes,and it usually hardens in less than 45 min-
utes,depending on temperature and adhesive thickness.

Instruction Set 2: Cast-In Adapters
I?" , Adapter type used: PRTA24 or PRTA30
Adhesive used: ADH100, MA320,SS115,or SS140
Bolt-down kit used: None
Step 2a:Apply Adhesive
Apply adhesive to the outside surface of the riser tank adapter.
Hint: If you plan to backfill the same day,the use of MA320,SS115 or
SS140 adhesive is recommended because of their quicker cure times.
Cast-in PRTA30 tank adapter If you have multiple riser installations and do not have bulk adhesive
(SS115/SS140),consider using both MA320 and ADH100.Apply just
® -
enough MA320 on the outside of the tank adapter for a quick structural
joint(cure time is typically less than an hour).A single package of
MA320 can be used to provide a structural joint on two or three risers.
Then apply ADH100 to the inside of the adapter and the riser joint,for a
watertight seal.
Step 2b: Place Riser
• Orient the riser correctly and carefully slide it onto the adapter before
the adhesive cures.
Step 2c: Seal Adapter-to-Riser Joint
Apply adhesive to the inside of the adapter and riser joint. Use a putty
knife or similar tool to form a continuous fillet between the tank adapter
and the inside of the riser.
Step 2d: Cure Adhesive
t I Allow adhesive to harden before backfilling. For ADH100, handling
strength is typically achieved within 12 hours. For MA320, cure time is
achieved within 30 minutes to 3 hours,depending on temperature.

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

Maintenance Instructions °61
omnco Systems'
Incorporated
1-800-348-9843
During the annual inspection,follow the testing procedures provided to ensure that the system is operating properly. If a float is
found to be faulty,either during the annual inspection or during troubleshooting after an alarm condition,see the section below
titled Removing and Replacing Inoperative Floats.
Removing and Replacing Inoperative Floats
Important Before doing any work either on the wiring to the level control floats and pump in the vault or in the pump control
panel,switch the circuit breakers in the panel to their"OFF"positions;then switch off the power to the system at the service
entrance panel.
1. Remove the float assembly from the vault.
2. Using a Phillips screwdriver, remove the stainless steel screws from the splice box lid,being careful not to drop the screws
into the tank. If the splice box was submerged,or if there is a crack in the conduit,there may be water in the splice box. If
this is the case,remove water from the splice box with a syringe,sponge,or other appropriate method. Loosen the cord grip
at the splice box and verify the appropriate splice for the float. Unscrew the wire nuts and remove the float.
3. Remove the inoperative float and replace it with a new one. Push the float cable through the watertight cord grip into the
electrical splice box. Leave an adequate length of electrical cord coiled inside the riser to allow for easy removal of the float
assembly. Do not remove the colored markers or the paper tags from the float cords, and do not tryto thread the markers and
