Dear Ms. Bernard:
The Durham County Department of Public Health has determined the above referenced property is served by a
discharging sand filter system.The site characteristics identified on the property do not meet the requirements of
15A NCAC Section .1900,therefore, no permits may be issued to repair the ground absorption sewage disposal
system. Municipal sewer is not currently available to the property.
Should you have any questions concerning this matter, please feel free to contact me at [phone].

Re: Application for Construction Authorization for Samuel Mayes
Property site: 3621 Gooch Rd, Durham, NC 27704
Environmental Health Division file number:401196 Parcel ID: 171164
Dear Samuel Mayes,
The Durham County Department of Public Health, Environmental Health Division on 10/3/23
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)
, ,IUnsuitable 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
to native 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 cl
assified 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(984)236-1850 or download it from the OAH web
site at http:l/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 150B-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 October 6, 2023 . 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. The Registered Agent for the Department of Health and
Human Services is Julie Cronin.
Do not serve the petition on your local health department. Sending a copy of your petition to the
local health department will not satisfy the legal requirement in N.C. General Statute
150B-23 that you send a copy to the Office of General Counsel, N. C. Department of Health and
Human Services.
You may call or write the local health department if you need any additional information or
assistance.

Project Name: 3621 Gooch Road
Site Address/ Location: 3621 Gooch Road, Durham, NC 27704
Dear Owner:
On June 25, 2024, Cheng Zhang conducted an on-site review of features located on the subject property
with your request to determine the applicability of the above-noted state regulations.
The Division of Water Resources has determined that streams listed in the table below and identified on
the attached maps are shown on either the most recently published NRCS Soil Survey of Durham County
and the USGS National Map at a scale that incorporates the National Hydrography Dataset High
Resolution data at 1:24,000 scale. Streams that are listed as "Subject"on the below table have been
located on the ground at the site and possess characteristics that qualify them to be at least intermittent
streams in accordance with the NC Stream Identification Manual v.4.11 and therefore subject to the
Neuse Buffer Rules. Please be aware that features identified as"not subject"may be considered
jurisdictional according to the US Army Corps of Engineers and subject to the Clean Water Act.

Dear Mr. Weaver,
Please consider this letter as a request for coverage under the General Permit for a Multi-
Phase Filter System. The proposed discharge system is for a 3-Bedroom Single Family
Residence (SFR) located in Durham County, North Carolina. The proposed discharge
system will replace the existing un-permitted sand-filter discharge system that is designed
to accommodate 3 bedrooms at 360 gallons/day. The proposed system is to be sized for 3
bedrooms at 360 gallons/day. The residence is located at 3621 Gooch Rd, Durham, NC
27704. Thank you for your assistance in this matter.

Soils Evaluation Summary
TO: Samuel Mayes, Client
FROM: Jeff Vaughan, Ph.D., L.S.S.
Senior Agronomist/Soil Scientist
SUBJECT: Soils Evaluation for 3621 Gooch Rd, Durham, NC 27704 (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 Durham,NC. The
evaluation was performed by Jeff Vaughan, L.S.S. of AWT. A single-family residence with an
existing sand filter discharge system is located on the property. The lot has been evaluated by
Durham County Department of Public Health and deemed to be unsuitable for any subsurface
on-site wastewater system option.
The soils on the subject properties are unsuitable for conventional and alternative subsurface
wastewater systems due to unsuitable topography and shallow depth to a soil wetness condition.
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 18E Section
.1000—Wastewater Treatment and Dispersal Systems -or- 15A NCAC 02T Section .0600—SFR
Wastewater Irrigation Systems. The site is a likely candidate for a surface water discharge
system.
Please contact us with any questions, concerns, or comments.

The drainage area for this discharge location is approximately 0.07 sq.mi.Given the drainage area is less than 0.1 sq.miles
the USGS streamflow records for extremely small basins are very limited to almost non-existent for North Carolina streams,
and all low-flow characteristics(7Q10,30Q2,W7Q10,and 7Q2)for these small drainage basins are presumed to be zero
flow or less than minimal flow(0.05 cfs).Moreover,this drainage area is located in Zone HA6.Still the drainage area is
below the threshold of 50 sq.mi.It remains to assume zero flow or less than minimal flow(0.05 cfs).

Good afternoon,
According to our map,the nearest sewer line (lime green) is on E Geer St. and is not accessible to this
property.
You will need to contact the Planning Dept. for inquiries regarding future plans to extend City
services. (The line would have to extend up E Geer St. and then all the way to the end of Gooch Rd in
order to connect to sewer)

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 flow estimate for the
downstream tributary of the proposed wastewater discharge point. The proposed discharge point is to a Blue Line
Stream on the subject property that flows to Panther Creek. The analysis from USGS indicates the 7Q10
discharge for the point in question is likely zero(Appendix F of package).
All applicants.
If you conclude that the proposed discharge will pass the "allowable discharge" criteria, then begin the EAA
preparation by summarizing the following general information about the proposed project:
■ Provide a description of the proposed project. If the project will be constructed in phases,
provide a schedule for constructing each additional phase, and provide the projected flow per
phase (see STEP 2).
Response: A wastewater discharge system is to be constructed for a 3-Bedroom Single Family Residence (SFR) located in
Durham County,North Carolina. The proposed system will replace an existing sand filter discharge system that
currently serves the residence. The proposed discharge location is to a stream on the subject property which
flows to the neighboring property where the flow path converges with a tributary to Panther Creek. The flow for
the system is 360 gpd.The proposed treatment system will include the following components:
Septic Tank with Effluent Filter
Recirculation Tank
AdvanTex AX-20 Treatment Pod
UV Disinfection Chamber
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
wastestreams can also have a toxic impact on a receiving freshwater system, proposed new
EAA Guidance Document Revision:October 2019
Page 4of12

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 facility. City of Durham Public Works, indicated
that the closet water and sewer connection is on E. Geer Street,which is approximately 0.4 miles,or 2,112 linear
feet, from the subject property (Attachment H of application package). At an estimate of $150/ft, a sewer
extension would cost over$316,800.There are no plans for a sewer extension in the area.
(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 a soil wetness condition. (Attachment 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/LIAR
Estimation for Topographical Variation 1,200 sqft
Estimated Area Required (Actual) 4,800 sqft
Approximate Area Available 4,644 sqft
The current property's land available for the sub-surface system is 4,644 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 has no land available for a non-discharge surface 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., so
there is not sufficient space for a non-discharge surface system, and the unsuitable soil conditions do not allow
for a non-discharge surface 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: The table below lists neighboring properties and the value of the land as listed by the Durham County GIS
website. The surrounding lots contain single-family residences, and vacant lots. The values listed in the
table do not reflect the value of the single-family residences.
While there are some neighboring vacant lots,the vacant areas are either located on the other side of a blue
line stream,or located across a public right of way. These would not be economically feasible options for a
single-family residence.

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(AX20 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 7,290 sqft *Veg cover on property
Application Rate 0.5 in/week `Fescue Grass
Acceptable Volume to Irrigate 304 ft3/week
= 325 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.
EAA Guidance Document Revision:October 2019
Page 8 of 12

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.
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
(7Q10, 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 there is 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/I and Total Suspended Solids = 30 mg/I. However, based on actual sample
results from similar treatment systems(other facilities using the same technology)in many cases,a BOD5 of
5 mg/I and NH3-N of 1 mg/I can be met. While weekly sampling of the treated effluent would confirm the
treatment results on a regular basis, the additional cost associated with the collection and testing of the
effluent would not be feasible for the homeowner.
3. Provide a description of the proposed wastewater treatment facilities, including a schematic
diagram of the major components and a site plan of the treatment facility with outfall line(s).
Response: Plans and schematic drawings can be found in Attachment K(of application package).

Page 9 of 12

4. Pr.vide documentation of the availability of required land and/or easement agreements.
Response: The proposed discharge system will be located on land owned by the applicant. See Attachment K (of
application package)for the proposed discharge system location.
5. C•nduct 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. Ni te: All direct discharge treatment systems must comply with Reliability Requirements
sp cified in 15A NCAC 2H.0124.
Response: I he system serves a private facility that is served by a private well and does not have elevated water storage
tanks. In the event of a power outage,water will not be available to the residence. There is storage available
in the system to hold some waste from the house until power is restored to the system. If 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 e aluate the possibility of a combination of wastewater alternatives that would minimize or
eliminate a d rect discharge alternative. For example, consider whether the facility can operate a land
application sy:.tem during the dry season when streamfiows are at their lowest and provide less dilution,and
operate an N'DES discharge system during the wet season when soils may not be as amenable to land
application an. 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 v. 'd cost comparisons among all technologically feasible wastewater alternatives identified in
STEP 3, a 20-,ear Present Value of Costs Analysis (PVCA) must be performed. A preliminary design level
effort is consi ered appropriate for comparing feasible options and their associated costs. For the PVCA cost
comparison, .11 future expenditures are converted to a present value cost at the beginning of the 20-year
planning peri.d. 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 sh uld include all monetary costs associated with construction,startup and annual operation and
maintenance .f a facility. All unit cost information must be provided, and costs must be referenced. Costs
can be referen ed in paragraph format by summarizing the sources utilized (e.g.,vendor quotes,realtor land
quotes, past .ids, Means Construction Index, etc). Vender quotes received for treatment units or other
components, s well as realtor land quotes, shall be included as well. For each treatment alternative
identified as t:chnologically feasible,costs should include,but not be limited to,the following:
Capital Costs
■ Land acquisition costs
EAA Guidance Document Revision:October 2019
Page 10 of 12

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:
C,
PV= C„ +�
,=i (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:
PV= C, +C (1 + 11
r)" n
r(1+r)
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 mu t include a Summary Cost Table, which summarizes present worth costs developed for all
technologica 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 alternati es, or possibly collect actual soil data to better characterize the land application alternative.
Ultimately, th 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 2.5%.

RE: Local Government Review Form Application for Discharge System
Mayes Residence—3621 Gooch Rd, Durham,NC 27704
Dear Ms. Page,
Enclosed please find a Local Government Review Form required for an Authorization to
Construct application supporting a proposed wastewater treatment system. The proposed
system will be permitted under the NCG550000 General Discharge Permit for Single Family
Residences. The proposed system will serve a 3-Bedroom Single Family residence (SFR)
located in Durham County, North Carolina. The proposed system will replace the existing
sand filter discharge system that currently serves the residence.
This site has been deemed unsuitable for ground absorption sewage treatment systems by
Durham County Public Health due to unsuitable soil characteristics and an unsuitable soil
wetness condition. 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.
The residence is located in Durham County.
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 919-859-0669.
Best Regards,

Narrative Description
of
Discharge Treatment System
The Discharge System that has been designed considers the following components:
- Septic Tank
-Recirculation Tank
-AdvanTex AX20 Treatment Pod
-UV Disinfection
-Discharge Outlet
-Control Panel
Due to the advanced technology in this system, a Certified Operator should he contracted to
maintain this system.
Septic Tank
A new 1,500-gallon traffic-rated septic tank will be installed for this system. The septic tank will
include an effluent filter and risers. An Orenco 8" Biotube effluent filter will be installed in the
outlet end of the septic tank. New access risers will be installed on both the inlet and outlet ends of
the septic tank. To facilitate the installation of the access risers,riser adapters will be cast into the
tank top during construction. All wastewater from the single-family residence,including greywater,
will be routed into the septic tank. Waste that exits the septic tank will flow via gravity into the re-
circulation tank.
Re-circulation Tank
The 1,000-gallon pump tank will be used as a re-circulation tank for this system. Waste that
overflows from the septic tank will enter the inlet end of the re-circulation tank. An inlet tee will be
installed in the re-circulation tank. A re-circulation pump will be located on the outlet end of the re-
circulation tank in order to deliver effluent to the Orenco AdvanTex treatment pod. As liquid exits
the treatment component(AdvanTex Pod),it will flow to the re-circulating splitter valve located in
the inlet riser ofthe re-circulation tank. For the flow that returns to the recirculation tank,depending
on the liquid level in the tank, the liquid will either return to the re-circulation tank or continue
through the system. Access risers will be installed on both the inlet and outlet side of the tank. To
facilitate the installation of the access risers,the tank will have riser adapters attached to the top of
the tank during installation of the system.
1

AdvanTex Treatment Pod
The treatment component of the system is a re-circulating media filter system. Liquid from the re-
circulation tank will be periodically(approximately every 15 min)pumped to the treatment pod and
sprayed over the media for treatment. The treated water will be collected via a bottom drainline and
then directed back to the re-circulation tank. The pod will be installed on a bed of gravel.
The supply line to the AdvanTex pod will also direct flow back to the septic tank. To control flow,a
ball valve will be installed on the line.
Re-circulating Splitter Valve
The re-circulating splitter valve is located on the inlet access riser of the re-circulation tank.
Depending on the liquid level in the re-circulation tank,the valve will either allow water back into
the re-circulation tank for further treatment or direct water to the disinfection component.
UV Disinfection
Disinfection for the system will be accomplished using a single bulb UV system with a pump
override. The UV light should operate in excess of one year prior to needing to be replaced. If the
UV light dims to a lower threshold(monitored by the control panel)an alarm light will illuminate on
the control panel to notify the operator. The control system for the UV unit is integrated into the
main control panel for the system. If the UV light fails to operate, the control panel will suspend
operation of the system pump thereby preventing liquid from discharging from the system. The UV
light is a gravity set-up ad will be located in a vault adjacent to the recirculation tank. This vault will
be separate from the other system components.
Discharge Outlet
After flowing through the UV system,water will fall into the chamber before flowing via gravity to
the discharge point. The discharge line will be buried a minimum of 18" until it reaches the
discharge outlet. Vegetation and debris should be kept clear of the discharge location. The outlet
pipe will be fitted with a grate to prevent animals or rodents from entering the pipe. Riprap will be
placed at the discharge location to provide aeration of the water as it is discharged and will also
serve as erosion protection.
Control Panel
One control panel will be installed with this wastewater system. Operation of the re-circulation
pump,UV system and discharge pump will be controlled by this panel. If desired,this panel can be
connected to a land-based phone line that will notify the operator of system operation.

Buoyancy Force= 12,251 lb.
Weight Calculation:
Tank Weight= 9,000 lb
Water Weight in Tank= 0 lb
Soil Weight Over Tank= 2,734 lb
Soil Tension Force= 2,869 lb
Total Weight= 14,603 lb
Note: Total weight must be greater than buoyancy force
so that tank will not float during high water table conditions.

Access Risers and Tank Adapters mS•
rporated
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 gram-
mets and joining PVC or fiberglass risers to ABS or fiberglass PRTA-
Q` ► style tank adapters(where the joint is in shear). Handling strength is
t ® w am, achieved within 12 hours,and full cure in 2 to 3 days. It comes in a
3 10.2-oz(300-mL) cartridge tube for application with a caulking gun.
+ F _ f ADH10(IPS810)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
ADH100,SS140,ADH845,ADH10(IPS810)pint and
MA320 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.

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.
I Step 2b: Place Riser
s 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.

concrete antiflotation collar has to be installed around the tank's mid-
seam. Contact your Dealer or a qualified engineer if you are unsure
whether a concrete collar is needed.
Step 16b: Backfill the pump basin if it hasn't been done yet.
• For Orenco PVC pump basins, see NIN-PB-1, PVC Basin Installation.
Step 16c:Backfill and compact around the AX20 unit in 12-in.(300-mm)lifts.
Key Points:
• Do not use native material to backfill if it is primarily sand; very soft or
highly expansive clay; or if it contains debris, large (> 3A-in.or 19-mm)
rocks, sharp rocks, peat,or muck. In these cases, use s 3/4-in. (s
19-mm) rounded gravel,crushed stone, or pea gravel as fill material.
This material should be washed,free-flowing,and free of debris.
• In noncohesive soils*with high seasonal water tables, use 3/4-inch
crushed rock as the backfill material.
• Do not backfill with sand.
Step 16d: Compact the fill thoroughly with a mechanical compactor.
Key Points:
• The bottom of the AX20 lid should sit 2 inches (50 mm) above final
grade.
Step 16e: Close and secure the AX20 unit's lid.
Step 16f:Secure the access lids on the tank and pump basin (if used).
Step 16g: Before the system goes into use,contact the system's Service
Provider and complete the system start-up together per AIM-OM-ATX-1,
AdvanTex O&M Manual:Start-Up and Routine Maintenance.
As described in OSHA Standards(29 CFR,Part 1926,Subpart P,Appendix A),noncohesive soils
or granular soils include gravel,sand,or sift with little or no clay content.Granular soil cannot be
molded when moist and crumbles easily when dry.Cohesive soils include clayey silt,sandy clay,
silty clay,clay,and organic clay.Cohesive soil does not crumble,can be excavated with vertical
sideslopes,is hard to break up when dry,and when moist,can be rolled into threads without
crumbling.For example,if at least a 2-inch(51-mm)length of 1/8-inch(3-mm)thread can be
held on one end without tearing,the soil is cohesive.

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

Step 7:
When used with an Orenco electrical splice box:
o
Push the level control wires through the watertight cord grips into the —
electrical splice box. Leave an adequate length of electrical cable coiled T
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 ,®
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
Orcn IncorporatedSySystems'
1-800-348-9843
During the annual inspection,follow the testing procedures provided to ensure that the system is operating properly. If a float is
found to be faulty,either during the annual inspection or during troubleshooting after an alarm condition,see the section below
titled Removing and Replacing Inoperative Floats.
Removing and Replacing Inoperative Floats
Important: Before doing any work either on the wiring to the level control floats and pump in the vault or in the pump control
panel,switch the circuit breakers in the panel to their"OFF"positions;then switch off the power to the system at the service
entrance panel.
1. Remove the float assembly from the vault.
2. Using a Phillips screwdriver,remove the stainless steel screws from the splice box lid, being careful not to drop the screws
into the tank. If the splice box was submerged,or if there is a crack in the conduit,there may be water in the splice box. If
this is the case,remove water from the splice box with a syringe,sponge,or other appropriate method. Loosen the cord grip
at the splice box and verify the appropriate splice for the float.Unscrew the wire nuts and remove the float.
3. Remove the inoperative float and replace it with a new one. Push the float cable through the watertight cord grip into the
electrical splice box. Leave an adequate length of electrical cord coiled inside the riser to allow for easy removal of the float
assembly. Do not remove the colored markers or the paper tags from the float cords,and do not try to thread the markers and
tag through the cord grip.Tighten the cord grip by hand,not by tool,then test the tightness of the cord grip by tugging on the
cord.A cord is secure when the cord grip is tight enough to prevent slippage.An adequate length of cord should be left
within the splice box to allow for easy removal for future disconnecting and resplicing.
4. Refer to document EIN-SB-SB-1 for instructions to splice the float wire to the wire from the control panel.Attach the float
wires using the waterproof wire nuts. It is necessary to replace this wire nut with a new watertight wire nut.Always use
watertight wire nuts or heat shrink splice kits for all connections!
5. Replace the float and collar and return the assembly to the pump vault.
6. Reconnect power and test the unit.

RE: Application for Coverage under General Permit and
Authorization to Construct—Mayes Residence
3621 Gooch Rd, Durham,NC 27704
Dear Mr. Weaver,
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. The
proposed system will replace an existing un-permitted sand filter discharge system that served
the former 3-bedroom residence. The former residence was damaged in a house fire and will be
demolished. The proposed system is sized for the new 3-bedroom home at 360 gallons/day. A
setback waiver has been granted for the on-site well, and the agreement is included in the
application package (Attachment G). The residence is located at 3621 Gooch Rd, Durham, NC
27704.
The following information is included with this letter:

The system discharges to a blue-line stream on the subject property that flows onto the
neighboring property before converging with a tributary to Panther Creek. The flow path
and drainage easement agreements are included in Attachment G. The discharge system
will include the following components:
New Septic Tank with Effluent Filter
New Recirculation Tank
AdvanTex Treatment Pod
UV Disinfection Chamber
Discharge Point with Rip-Rap
Flow Path to"Blue Line" Water Feature
The flow path is to a blue-line stream on the subject property that flows onto the
neighboring property where the flow path converges with a tributary to Panther
Creek. A map showing the flow path from the discharge point can be seen in
Attachment G. The latitudinal and longitudinal information presented below is the
approximate location of the confluence of the flow path with Panther Creek.

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. City of Durham
Public Works indicated that the closest water and sewer connection is on E. Geer Street,
approximately 0.4 miles, or 2,112 linear feet, from the subject property (Attachment H).
At an estimate of$150/ft, a sewer extension would cost over$316,800.

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.
Durham County Department of Public Health deemed the site unsuitable for a sanitary
system of sewage treatment and disposal due to unsuitable soil characteristics and an
unsuitable wetness condition. The improvement permit denial letter is dated October 6,
2023. The denial letter is included(Attachment B).
Investigate Land Application such as spray irrigation or drip irrigation.
Per the soil evaluation by Jeff Vaughan, Ph.D., L.S.S. of Agri-Waste Technology, Inc.,
the soils on the subject property are unsuitable for conventional and alternative
subsurface wastewater systems due to unsuitable topography and shallow depth to a soil
wetness condition. 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(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
a tributary of Panther Creek on the subject property. The analysis from USGS indicates
the 7Q10 discharge for the point in question is likely zero or less than minimal flow
(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
As part of the EAA, Local Government Review Forms were sent to Durham County and
the City of Durham. A copy of the submittal is included as Attachment J. To date, the
signed County and City forms have not been signed and returned.
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.
