RE: Application for Discharge System—Koneru Property North l�f.lii 2 2022
2219 Clements Drive, Durham,NC 27704 NCDE( IDWRINPDES
Dear Mr. Hennessy,
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 the unpermitted discharge system that currently serves the
residence. The site has been deemed unsuitable for ground absorption sewage treatment systems
by the Durham County Environmental Health Department due to unsuitable soil characteristics
and insufficient space. The proposed system is to be sized for 3 bedrooms (360 gallons per day)
and has been designed to convey all wastewater from the SFR, including greywater, to the new
septic tank. The site's existing septic tank is to be abandoned. This application is being
submitted with the intent to have coverage under the NCGS5 General Permit. Coverage under
this permit is sought to replace an unpermitted sand filter system.
The following information is included with this letter:
Notice of Intent(NCG550000). Attachment A.
$60 check payable to North Carolina DENR.
Documentation from Durham County Health Department. Attachment B.
Letter requesting coverage under the General Permit. Attachment C.

The proposed discharge point is in an unnamed tributary of Ellerbe Creek, located near
the northeastern corner of the property. This discharge point is located on the subject
property. The discharge system will utilize the following components:
- Septic Tank with Effluent Filter
AdvanTex AX-20 RT Pod
Re-circulation Pump Chamber(Integrated into AdvanTex Pod System)
UV Disinfection
- Discharge Point with Rip-Rap
Flow Path to "Blue Line"Water Feature
The proposed discharge location is in an unnamed tributary to Ellerbe Creek, the
Blue Line Feature. This flow path is currently utilized by the existing,
unpermitted sand-filter discharge system on the property. A map showing the
path from the discharge point to the first "blue-line" stream, as shown on the
Durham County GIS data, 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 Ellerbe Creek.

Latitude 36.041822°
Longitude 78.857050°
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. Unity Bailey, an
Engineering Technician with the Durham Public Works Department, indicated that the
property is not within the city's coverage area. The closest current city maintained sewer
is approximately 415 linear ft. from the property and there are no immediate plans for a
sewer extension to the area at this time (Attachment H). Although city maintained sewer
is approximately 415 ft away, that path would require crossing privately owned property;
the actual distance of a sewer expansion would need to be much greater to reach the
property. The property is not within the city limits of the City of Durham and would need
to be annexed in order for sewer expansion to be possible.

Letter from the local or county health department describing the suitability or non-
suitability of the site for all types of wastewater ground adsorption and innovative
non-discharge systems. Document the repair potential of the failed system.
The Durham County Environmental Health Department indicated that the site is
unsuitable for installation of a ground absorption septic system in letter dated December
20, 2021 (Attachment B). The letter indicated that a permit cannot be issued due to
unsuitable soil topography and unsuitable soil depth.
Investigate Land Application such as spray irrigation or drip irrigation.
Per the soil evaluation by Chris McGee, 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 in
an existing drainage ditch that leads to an unnamed tributary to Ellerbe Creek. 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
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
completed forms have not been received.

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.

Dear Konern Rao,
On December 16, 2021, the Durham County Department of Public Health, Environmental
Health Division on evaluated the above referenced property for an existing single family
dwelling 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 Authorization to Construct. A copy of the site evaluation is enclosed. The site is unsuitable
based on the following:
Unsuitable soil topography and/or landscape position (Rule .1940)
Unsuitable soil characteristics (structure or clay mineralogy) (Rule .1941)
Unsuitable soil wetness condition (Rule .1942)
Unsuitable soil depth (Rule .1943)
Presence of restrictive horizon (Rule .1944)
Insufficient space for septic system and repair area (Rule .1945)
I Unsuitable for meeting required setbacks (Rule .1950)
These severe soil or site limitations could cause premature system failure, leading to the
discharge of untreated sewage on the ground surface, into surface waters, directly to ground
water or inside your structure.
The site evaluation included consideration of possible site modifications, as well as use of
modified, innovative, or alternative systems. However, the Health Department has determined
that none of the above options will overcome the severe conditions on this site. A possible
option might be a system designed to dispose of sewage to another area of suitable soil or off-
site to additional property.
For the reasons set out above, the property is currently classified UNSUITABLE, and no
construction authorization permit shall be issued for this site in accordance with Rule .1948(c).

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

15A NCAC 18A.1948 SITE CLASSIFICATION
(a)Sites classified as SUITABLE may be utilized for a ground absorption sewage treatment and disposal system
consistent with these Rules.A suitable classification generally indicates soil and site conditions favorable for the
operation of a ground absorption sewage treatment and disposal system or have slight limitations that are readily
overcome by proper design and installation.
(b)Sites classified as PROVISIONALLY SUITABLE may be utilized for a ground absorption sewage treatment and
disposal system consistent with these Rules but have moderate limitations.Sites classified Provisionally Suitable
require some modifications and careful planning,design,and installation in order for a ground absorption sewage
treatment and disposal system to function satisfactorily.
(c)Sites classified UNSUITABLE have severe limitations for the installation and use of a properly functioning ground
absorption sewage treatment and disposal system.An improvement permit shall not be issued for a site which is
classified as UNSUITABLE.However,where a site is UNSUITABLE,it may be reclassified PROVISIONALLY
SUITABLE if a special investigation indicates that a modified or alternative system can be installed in accordance with
Rules.1956 or.1957 of this Section.
(d)A site classified as UNSUITABLE may be used for a ground absorption sewage treatment and disposal system
specifically identified in Rules.1955,.1956,or.1957 of this Section or a system approved under Rule.1969 if written
documentation,including engineering,hydrogeologic,geologic or soil studies,indicates to the local health department
that the proposed system can be expected to function satisfactorily.Such sites shall be reclassified as
PROVISIONALLY SUITABLE if the local health department determines that the substantiating data indicate that:
(1)a ground absorption system can be installed so that the effluent will be non-pathogenic,non-infectious,
non-toxic,and non-hazardous;
(2)the effluent will not contaminate groundwater or surface water;and
(3)the effluent will not be exposed on the ground surface or be discharged to surface waters where it could
come in contact with people,animals,or vectors.
The State shall review the substantiating data if requested by the local health department.

You application states 4 bedrooms. Properties of that time and area are typically 3 bedrooms,which corresponds with the
tax record. Would you like to pursue an expansion, or proceed with a 3 bedroom repair?An expansion will require
additional permitting and applicable permit fees. A repair requires a written response (email in fine), clarifying 3 bedrooms

In accordance with North Carolina law,approval for construction or replacement of a septic system occurs when the Health Department issues an
Improvements Permit and a Construction Authorization.The process of obtaining these permits requires a"Site and Soil Evaluation"by Health
Department Environmental Health Specialists in compliance with the"Laws and Rules for Sewage Treatment and Disposal Systems"(15 NCAC 18 A
.1900).Soil structure,texture,clay mineralogy,topography,landscape position,soil wetness,soil depth,restrictive horizons and available space are
among the criteria considered in this evaluation.The results of this evaluation determine whether an Improvements Permit can be issued,the number
of bedroom a house can have,and the location of the house and the well serving it.
Once the Improvements Permit is issued,the owner is protected for the duration of the permit from subsequent changes in the rules governing
septic tank systems unless alterations arc made to the property which damages the area reserved for the septic tank system installation and for the
intended use changes.If the septic system is not installed before permit expiration,the owner must re-apply for an Improvement Permit and will be
subject to any new regulatory changes that may have transpired.An Improvement Permit for which a plat is provided shall be valid without expiration
and an Improvement Permit for which a site plan is provided shall be valid for 60 months from the date of issue as provided in G.S.[130A-335(f)and

L219 Clements Drive, Durham,NC 27704
Dear Mr. Hennessy;
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 the replace unpermitted discharge system that currently serves the residence.
The site has been deemed unsuitable for ground absorption sewage treatment systems by
the Durham County Environmental Health Department due to unsuitable soil
characteristics and insufficient space. The proposed system is to be sized for 3 bedrooms
at 360 gallons/day. The residence is located at 2219 Clements Drive, Durham, NC
27704.
Thank you for your assistance in this matter.

MEMORANDUM
TO: Dr. Koneru R. Rao do Sarat Koneru &Rick Soles Property Management, Inc.
FROM: Chris McGee, LSS
SUBJECT: Soils Evaluation for 2219 Clements Drive, 2224 Clements Drive, 2223 Clements
Drive, & 2227 Clements Drive
Durham,NC (Durham County)
Agri-Waste Technology, Inc. (AWT) was contracted to perform a soils evaluation for the
purposes of on-site wastewater system suitability at the subject properties in Durham, NC. The
evaluation was performed by Heath Clapp and supervised by Chris McGee of AWT on
December 21, 2021 and May 4, 2022. Single-family residences with unpermitted wastewater
systems are located at 2219 Clements Drive and 2224 Clements Drive. 2219 Clements Drive and
2224 Clements Drive have both been deemed unsuitable for subsurface wastewater systems by
the Durham County Environmental Health Department.
The soils on the subject properties are unsuitable for subsurface and surface application
wastewater systems due to shallow wetness conditions, shallow depth to expansive clay
mineralogy, and insufficient space. Therefore, these properties do not comply with the
requirements of 15A NCAC 18A Section .1900 — Sewage Treatment and Disposal Systems -or-
15A NCAC 02T Section .0600—SFR Wastewater Irrigation Systems. 2219 Clements Drive and
2224 Clements Drive are likely candidates for surface water discharge systems.

Subject: USGS response to DWR USGS Low Flows request#2022-169(dated 2022/01/06)for UT Ellerbe Creek
Durham County...RE: [EXTERNAL] Low-flow request approval
Ms. Davidson,
In response to your inquiry about the 7Q10/3042 low-flow characteristics for a "drainage ditch"to an unnamed
tributary to Ellerbe Creek upstream from Cartman Drive(NC Secondary Road 1712) near Weaver(vicinity of
Durham) in central Durham County,the following information is provided:
A check of the low-flow files here at the USGS South Atlantic Water Science Center(Raleigh office)does not
indicate a previous low-flow determination for the point of interest, identified by the lat/long coordinates
(36.04075,-78.86658) provided via email dated 01/06/2022 from the DWR USGS Low Flow portal following your
request submission (initially submitted 12/15/2021).
No USGS discharge records are likewise known to exist for the point of interest.
In the absence of site-specific discharge records sufficient for a low-flow analysis,estimates of low-flow
characteristics at ungaged locations are determined by assessing a range in the low-flow yields(expressed as flow
per square mile drainage area, or cfsm)at nearby sites where estimates have been determined.
A basin delineation completed using the online USGS StreamStats application for North Carolina
(hops://streamstats.usgs.gov/ss/)indicates the drainage area for the point of interest(StreamStats adjusted
coordinates 36.04076,-78.86658 NAD83) is 0.22 sqmi,which confirms the drainage area submitted as part of the
request information.
L

For streams in central Durham County,low-flow characteristics published by the USGS are provided in the
following reports:
(1)The first is a statewide report completed in the early 1990's. It is USGS Water-Supply Paper 2403, "Low-flow
characteristics of streams in North Carolina" (Giese and Mason, 1993). An online version of the report is available
at https://pubs.usgs.gov/wsp/2403/report.pdf. The report provides the low-flow characteristics (based on data
through 1988)via regional relations and at-site values for sites with drainage basins between 1 and 400 sqmi and
not considered or known to be affected by regulation and/or diversions.
(2)The second is a basin-wide report for the Neuse River basin published in 1998. It is USGS Water-Resources
Investigations Report 98-4135, "Low-flow characteristics and discharge profiles for selected streams in the Neuse
River basin, North Carolina" (Weaver, 1998). The report is available online at
http://pubs.usgs.gov/wri/1998/4135/report.pdf. This report provides low-flow characteristics (based on data
through 1996)for USGS continuous-and partial-record sites in the Neuse River basin where sufficient data was
available for analyses. However,the report does not provide statistical relations for estimating low-flow
characteristics at ungaged locations.
(3)The third is a statewide report published in March 2015. It is USGS Scientific Investigations Report 2015-5001,
"Low-flow characteristics and flow-duration statistics for selected USGS continuous-record streamgaging stations
in North Carolina through 2012" (Weaver,2015). The report is available online at
http://pubs.usgs.gov/sir/2015/5001/. The report provides updated low-flow characteristics and flow-duration
statistics for 266 active(as of 2012 water year)and discontinued streamgages across the state where a minimum
of 10 climatic years discharge records were available for flow analyses.
Low-flow characteristics estimated for point of interest:
Visual inspection of the stream location on a topographical map suggests a small basin area upstream from the
point of interest. As noted above,the drainage-area for the basin upstream from the point of interest is 0.22
sqmi.
On pages 33-34 of the Neuse basin-wide low-flow report(second reference above) is information about the
Occurrence of Zero or Minimal 7Q10 Discharge that is likely to occur for a stream within the major basin,
contingent on the size of the upstream drainage basin. The discussion on page 33 in this section indicates that
poorly drained soils(that is,soils having low infiltration rates)are a primary factor in numerous occurrences of
zero 7010 discharges in the upper end of the study area [Neuse River basin]:
"Much of the water that comes in contact with the soils in this area most likely enters the streams as overland
runoff and does not infiltrate into surficial aquifers for later release during drought conditions.Among sites having
zero 7Q10 discharges, the drainage areas range from less than 0.01 mi2(site 10)to about 44 mi2(site 121). For
sites in this area having non-zero 7Q10 discharges, the average 7Q10 unit low flow is about 0.005(ft3/s)/mi2.
Therefore,sites with drainage areas less than about 10 mi2 could be expected to have zero or minimal 7010
discharges(less than 0.05 ft3/s)."
Parts of the basin upstream from the point of interest are underlain by the Triassic basin geologic unit. From a
hydrologic perspective,streams underlain by this geologic unit have very little to no potentials for sustained base
flows during extended dry periods. At sites underlain by the Triassic basin where the USGS has collected sufficient
records for low-flow analyses,the low-flow characteristics for sites having drainage areas that would typically be
expected to have sustained flows actually have some of the lowest low-flow estimates in the state.
Consideration of the above information results in a conclusion the 7Q10 discharge for the point of interest is zero
flow.

For the record:There is very limited streamflow data for small basins in North Carolina. As such, only the low-
flow estimate for the annual 7Q10 discharge is formally provided. No formal estimated low-flow discharges are
provided for the annual 30Q2,winter 7Q10,or annual 7Q10 discharges. Similarly, no estimated average annual
discharge is provided. However, based on visual inspection of several nearby index sites (02085059,0208700780,
02087024, and 02087238)with drainage areas less than about 10 sqmi and with estimated 30Q2 discharges at
zero flow,the annual 30Q2, winter 7010, and annual 7Q10 discharges would very likely be estimated at zero flow
for your point of interest having a drainage basin at 0.22 sqmi.
Please understand the information provided in this message is based on a preliminary assessment and considered
provisional,subject to revision pending further analyses.
This low-flow response is provided via the DWR USGS Low Flows cooperative agreement between the USGS and
the N.C. Department of Environmental Quality, Division of Water Resources.
Hope this information is helpful.
Thank you.

Engineering Alternatives Analysis (EAA) Guidance Document
North Carolina Division of Water Resources
STEP 1. Determine if the proposed discharge will be allowed
Non-municipal applicants.
Due to staff constraints, the NPDES Unit cannot prepare speculative limits for non-municipal applicants.
Thus,it is your responsibility to make your own determination as to whether the proposed discharge might be
allowed by the Division, by evaluating the water quality factors listed above. It is highly recommended that
you discuss the proposed discharge with the applicable DWR Regional Office and/or NPDES Unit staff,who
may be able to provide input on the likelihood of a new/expanding discharge. As a first step, you must
obtain streamflow estimates for the proposed discharge location to ensure that the receiving stream is not
subject to zero flow restrictions. Low flow data (specifically, drainage area, the summer and winter 7Q10,
average flow and 30Q2 flow statistics) can be obtained for a nominal fee from the U.S. Geological Survey in
Raleigh at 919-571-4000. The low flow data must be submitted with the EAA, and will be used by the permit
writer to develop permit limits. You must also verify that the proposed action (i.e., construction of a
wastewater treatment plant and its appurtenances) is consistent with local zoning and/or subdivision
ordinances. You will need to request the local government(s) to complete a Local Government Review Form
(Attachment A),and include the signed and notarized form with your NPDES application package.
Response: The United States Geological Survey (USGS) was contacted to determine the 7Q10 flow estimate for the
downstream tributary of the proposed wastewater discharge point. The proposed discharge point is in an
unnamed tributary of Ellerbe Creek. The analysis from USGS indicates the 7Q10 discharge for the point in
question is likely zero (Attachment F of application package). Because this is an existing treatment system with
zero flow,the discharge will be considered on a case-by-case basis.
All applicants.
If you conclude that the proposed discharge will pass the "allowable discharge" criteria, then begin the EAA
preparation by summarizing the following general information about the proposed project:
• Provide a description of the proposed project. If the project will be constructed in phases, provide a
schedule for constructing each additional phase, and provide the projected flow per phase (see STEP 2).
Response: A wastewater discharge system is to be constructed for a 3-Bedroom Single Family Residence(SFR) located in
Durham County, North Carolina. The proposed system will replace an unpermitted system that currently serves
the residence. The proposed discharge point is in an unnamed tributary of"Ellerbe Creek.The proposed treatment
system will utilize the following components:
New Septic Tank with Effluent Filter
AdvanTex AX-20 RT Pod
Recirculation Pump Chamber(Integrated into AdvanTex Pod System)
UV Disinfection
Discharge Point with Rip-Rap
Construction of the proposed system will occur in a single phase with an anticipated completion time of
approximately 2 weeks after the start of construction activity.

STEP 2. Provide reasonable projections for population and flow
Residential Population Projections.
Facilities requesting an NPDES discharge permit for new or expanding domestic wastewater discharges
must document the population to be served within the service area over a 20-year planning period. The NC
State Demographics unit provides population data for each county and municipality and can be accessed on
the Internet at http://www.demog.state.nc.us. If 20-year population projections for specific areas are not
available, a linear extrapolation of population trends from the past decade should be used. Any deviation
from a linear projection method must be clearly justified. If population projections include future
annexations, include a proposed annexation schedule as well as any annexation requirements that must be
met.
Response: Because the wastewater treatment system is designed for a single-family residence, the population to be served
will be limited by the number of bedrooms at the individual residence. The existing house contains 3 bedrooms.
For the 20-year planning period, the system will be designed for a 3-bedroom residence with a flow of 360
gallons per day. At 2 people per bedroom,the system will be designed to serve 6 residents.
STEP 3. Evaluate technologically feasible alternatives
Alternative A. Connection to an Existing Wastewater Treatment System.
You must evaluate the feasibility of connecting to an existing wastewater treatment system served by a
municipality or other entity holding a valid NPDES or Non-Discharge Permit. All connection options
should include an evaluation of a gravity line and/or force main with pump station(s).
1. Existing Sewerage System:
(a) Identify whether there are existing sewer lines within a five-mile radius,or consider a greater
radius if cost effective for the project size.
Response: Connection to a sewer collection system is not feasible for this facility. Unity Bailey, an Engineering Technician
with the Durham Public Works Department, indicated that the property is not within the city's coverage area.The
EAA Guidance Document Revision:April 2014
Page 2 of 8

closest current city maintained sewer is on Sundial Circle. While this sewer line is only approximately 415 linear
ft.from the property, it is not accessible for the property in question.
There are no immediate plans for a sewer extension to the area at this time(Attachment I-I). The property has no
access to the sewer line on Sundial Circle. For the property to have access to sewer, it would need to be extended
along Clements Drive. To get to Clements Drive, sewer would also have to extend down Thompson Road and
Colonial Heights Drive. Since none of the properties on this route are in the City of Durham,they would all have
to be annexed in for this to be possible.
Extending sewer from Old Oxford Road to the property would be a minimum of 5,564 ft. For reference, if an
installation cost of$100/ft of installed sewer line was assumed,the cost to connect this property to the sewer line
would be approximately $556,400. Additional costs including the cost of the pump station, potential "tap" or
sewer capital fees,road repair costs, frontage fees and fees for right of way permits would also be incurred by the
homeowner.
(b) Provide a preliminary indication of flow acceptance from existing municipal or private
WWTPs under consideration for connection. If a municipal or private WWTP cannot accept
the wastewater, include a letter documenting such and consider this alternative
technologically infeasible.
Response: N/A No sewerage available
(c) If an existing sewerage system will accept the wastewater, evaluate the
piping/pumps/resources necessary to connect to the existing wastewater treatment plant.
Attach a topographic map or a site drawing showing the physical route of this alternative.
Conduct a Present Value Cost Analysis per STEP 4.
Response: N/A No sewerage available
2. Planned Sewerage System: Determine if a regional sewerage system within a five mile radius is
projected to be available within the next five years to receive waste from the project site. If
applicable, determine availability date and flow acceptance projection from appropriate
authority.
Response: As stated above,the City of Durham's sewerage system currently exists within five miles of the property, but a
connection to this system is infeasible due to the cost. According to the Durham Public Works Department,there
are no known plans to bring the city sewer system closer to the applicant's property.
Alternative B. Land Application.
Land application disposal alternatives include individual/community onsite subsurface systems, drip
irrigation,and spray irrigation.
1. Provide an estimate of the best case hydraulic loading rate based on County Soil Surveys or from
a soil evaluation performed by a soil scientist. Include calculations showing the hydraulic
loading rate and the total area of land needed for the land disposal system,including buffers.
Response: The Durham County Environmental Health Department indicated that the site is unsuitable for installation of a
ground absorption septic system in a letter dated December 20, 2021 (Attachment B of application package).
The letter indicated that a repair permit cannot be issued due to unsuitable soil topography and unsuitable soil
depth.
Per the soil evaluation by Chris McGee of Agri-Waste Technology, Inc. the site does not have adequate space or
suitable soil to accommodate a ground absorption or surface drip or surface spray wastewater system
(Attachment E of application package).
Regardless of the fact that a subsurface ground absorption can not be designed or permitted for this site, the
potential size of a subsurface system has been estimated. According to the county soil survey, the site is
classified as a White Store series soil. For a subsurface system in this soil, a drip system with pretreatment
EAA Guidance Document Revision:April 2014
Page 3 of 8

would be required. This White Store soil is a sandy loam soil that would have a long-term acceptance rate
(LTAR) ranging from 0.05-0.2 gpd/sq.ft., with a typical rate of 0.1 gpd/sq.ft. Subsurface systems also require
the drainline to be installed with the contour so that each drainline is at a constant elevation. This results in a
"fanning"of the drainline and requires additional space in order to install the required amount of drainline. The
sizing calculation is summarized in the table below:
Subsurface Dripfield Design Alternative

I#Bedrooms 3
1 Daily Flow 360 gpd = 120 gpd•#bedrooms
{LTAR 0.1 gpd/sqft
Minimum Area Required (Nominal) 3,600 sqft =Daily How/LTAR
Estimation for Topographical Variation 1,200 sqft
Estimated Area Required (Actual) 4,800 sqft
1
;Approximate Area Available 32,588 sqft
The current property's land available for the system is 32,588 sq. ft., due to setbacks and existing site
conditions. This area includes the adjacent vacant properties owned by the applicant. This area also considers
maintaining a 50' well setback. A schematic of this area is shown in Appendix A of the EAA. The land
needed for a subsurface dripfield design is a minimum of 4800 sq. ft.,so there may be sufficient space for this
type of system at the residence.
The potential size of a non-discharge surface application system has also been estimated. According to the
county soil survey, the site is classified as a White Store soil. For a surface system in this soil, the SFR
loading rate group is likely restricted to a maximum annual loading of 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
lApproximate Area Available 9,742 sqft
The current property's land available for a surface drip or spray system is 9,742 sq. ft., due to setbacks and
existing site conditions. This area includes the adjacent vacant properties owned by the applicant. 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 insufficient space at this residence. The potential waiving of property
setbacks was taken into account when considering the available application area for surface systems.
2. Assess the availability of land. If insufficient land is available onsite, assume that the necessary
land can be purchased and estimate the land purchase cost based on local real estate prices.
Alternatively,provide documentation to demonstrate that insufficient land is available for sale in
the project area (include letters from adjacent property owners indicating no interest in selling
property).
Response: Because insufficient land is available onsite, offsite land was reviewed. The table below lists neighboring
properties and the value of the land as listed by the Durham County GIS website. The surrounding lots
contain single-family residences. The values listed in the table do not reflect the value of the single-family
residences. The soil types listed for these properties is White Store. These sites will be very restrictive for
wastewater systems.

3. Provide a description of the wastewater treatment system and the non-discharge application
system. Include a site plan showing the proposed layout, the application area, any existing
structures,proposed structures,and other uses within the site.
Response: A typical subsurface drip system or a non-discharge surface spray or surface drip system with pretreatment
considers the following components:
-Septic Tank with Effluent Filter
-Recirculation Tank(Integrated in AX20-RT unit)
-AdvanTex Treatment Pod(AX20-RT unit)
-Pump Tank(potentially integrated in AX20-RT unit)
-UV Disinfection(Integrated in AX20-RT unit)
-Headworks Box
-Control Panel
-Disposal Field(drip or spray)
Note:The proposed discharge system does not consider the pump tank,headworks box or disposal field.
Site drawings of these alternative systems showing the available application area are included as Appendix A
of the EAA. Due to the size requirements of a drip or spray system and the limited available space,there is no
ability to consider any of these systems on this property. Additionally, this property is not suitable for a non-
discharge surface drip or spray system due to limitations caused by the soil characteristics and conditions.
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 in Appendix A, there is
sufficient area to utilize the daily flow of reclaimed water. Although there may be sufficient space, due to
limitations caused by the soil characteristics and conditions, this property is not suitable for on-site
utilization of reclaimed water. Regardless of the fact that the soil at this site is not suitable for this system,
installing this system would not be feasible due to costs.

5. Conduct a Present Value Cost Analysis per STEP 4. For the reclaimed water system include the
potential revenue generated by selling the water.
Response: A Present Value Cost Analysis is included as Appendix B of the EAA. An analysis was performed for a
sub-surface drip system, a non-discharge surface application system, and a reclaimed water system. A
summary of the analysis is included in STEP 4.
6. Provide all calculations, documentation and maps as necessary to support assumptions and
conclusions.
Response: Calculations performed to evaluate land application alternatives are shown above in Alternative B, Points I
and 4.
7. Note: The design of land application systems must meet the treatment and design requirements
specified in 15A NCAC 2T .0500 or 15A NCAC 18A.1900.
Response: The treatment systems specified above in Step B would meet the treatment standards required by these rules
as they pertain to single family residences. However, because of the lack of available space and other
restrictions listed above, no land-based systems can be considered.
8. Note: Proposed discharges from groundwater remediation systems must evaluate the potential
for an infiltration gallery treatment alternative.
Response: N/A
Alternative C. Wastewater Reuse.
You must evaluate reusing all or a portion of the wastewater generated. Some municipalities are currently
reusing wastewater within the confines of their WWTP property for irrigation, toilet flushing, backwashing,
etc.,while other municipalities have established progressive reuse programs for residential irrigation. Reuse
applications might include golf course irrigation, crop irrigation (e.g., hardwood or pine plantation,
grasses), athletic field irrigation, landscape uses, and commercial/industrial uses. Some of these reuse
applications will be evaluated under Alternative B, Land Application. The design of reclaimed water
systems must meet the treatment and design requirements specified in 15A NCAC 2U.
Response: All reuse applications for this project scale were evaluated under Alternative B,Point 4. Wastewater reuse
was determined to be infeasible for this project.
Alternative D. Direct Discharge to Surface Waters.
1. No new or expanding (additional) discharge of oxygen-consuming waste will be allowed to
surface waters of North Carolina if both the summer 7Q10 and 30Q2 streamflows are estimated
to be zero, in accordance with 15A NCAC 2B.0206(d). Private applicants must contact the USGS
in Raleigh at 919-571-4000 and obtain (generally for a nominal fee),the receiving streamflow data
(s7Q10,30Q2, annual average streamflow) at the proposed discharge location. This information
must be included in the EAA, and will be used to develop permit limits.
Response: Because this is an existing treatment facility with estimated zero flow at the discharge point and no
expansion in discharge proposed,the discharge will be considered on a case-by-case basis.
2. All direct discharge systems of oxygen-consuming wastes should be evaluated both with tertiary
filtration [BOD5= 5 mg/I, NH3-N= 1 mg/1] and without, and assuming a weekly sampling
regime.
Response: Tertiary filtration is not required under the general permit, as the general permit requirements (monthly
average) are BOD5 = 30 mg/I and Total Suspended Solids = 30 mg/I. However, based on actual sample
results from similar treatment systems(other facilities using the same technology) in many cases,a BOD5 of
EAA Guidance Document Revision:April 2014
Page 6 of 8

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

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

RE: Local Government Review Form
Application for Discharge System—Koneru Property North
2219 Clements Drive,Durham,NC 27704
Dear Ms. Page,
Enclosed please find a Local Government Review Form required for a Certificate of
Coverage application supporting a proposed wastewater treatment system. The proposed
system will be permitted under the NCG550000 General Discharge Permit for Single Family
Residences (SFRs). The proposed system will serve an existing 3-Bedroom SFR located in
Durham County, North Carolina. The proposed system will replace the unpermitted
discharge system that currently serves the residence.
The site has been deemed unsuitable for ground absorption sewage treatment systems by the
Durham County Environmental Health Department due to unsuitable soil conditions and
insufficient space. It is my opinion that a wastewater treatment system covered by the
General Discharge Permit is the only technologically and economically feasible option for
this residence.
Please complete the enclosed form for inclusion in the application for the proposed system.
This residence is located in Durham County and is not located in the Durham City limits.
Please note that this form is only meant to determine zoning/jurisdiction information and
does not indicate your approval of the proposed system.
I appreciate your time and efforts in completing this form. If you have any questions or
comments, please feel free to contact me at 919-859-0669.
Best Regards,

Narrative Description
of
Discharge Treatment System
The Discharge System that has been designed considers the following components:
- Septic Tank
-AdvanTex AX20-RT Treatment Pod
-UV Disinfection
-Discharge Outlet
-Control Panel
Due to the advanced technology in this system, a Certified Operator should he contracted to
maintain this system.
Septic Tank
A new 1,250-gallon 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 into the AdvanTex AX20-RT
Treatment Pod.
AdvanTex AX20-RT Treatment Pod
The treatment component of the system is an AdvanTex AX20-RT treatment pod. The pod is an
integrated unit that combines recirculation,treatment, and discharge modules into a single, sealed
unit. Liquid from the septic tank will flow via gravity to the inlet of the treatment pod and into the
recirculation tank portion of the AX-RT unit. Liquid from the recirculation tank will be periodically
applied across the filter fabric. Wastewater will be sprayed over the textile sheets. The wastewater
percolates down through the textile sheets and is distributed between the recirculation chamber and
discharge chamber by means of the tank baffle. The treated wastewater exits the AX-RT unit via
gravity to the discharge outlet. Prior to exiting the AX-RT unit, effluent passes through the UV
disinfection system.
The recirculation pump is controlled by a system of 3 floats that operate the recirculation pump in a
Timed Dose arrangement. Float 1 (lowest elevation) is a redundant off float. Float 2 is a Peak
Enable Float and Float 3 acts as a High Water Alarm. Under normal operation the redundant off
float will be engaged thereby activating the timer in the control panel. At the pre-set interval,the
pump will engage and distribute effluent over the textile fabric("on"cycle). Following this period,
the pump will turn off and rest for a designated time("off"cycle)". During periods of high water in
the recirculation portion of the tank,the Peak Enable float will engage and reduce the pre-set"off"
time and thereby send increased flow across the fabric. If the water level in the recirculation tank
continues to rise for a pre-set time period,the High Water Alarm will activate.
1

To prevent groundwater from affecting the pod,the pod will be installed on a bed of gravel. Anti-
flotation measures or a concrete ring installed around the mid-flange will be installed to provide
extra ballast to prevent the flotation of the pod during high water table conditions.
UV Disinfection
Disinfection for the system will be accomplished using a UV system. The UV light should operate
for approximately one year prior to needing to be replaced. If the UV light burns out or loses
sufficient intensity(below a set threshold)an alarm will activate and disable the system pump. An
alarm light on the control panel will also illuminate. When the alarm is activated,the homeowner
should reduce water use (laundry, dishes,washing)until the system is operating properly.
Discharge Outlet
The system discharges into an unnamed tributary of Ellerbe Creek, located near the northeast
property corner. Riprap will be placed at the discharge location to provide aeration of the water as it
is discharged and also as erosion protection. Vegetation and debris should be kept clear of the
discharge location. A grate will be installed on the discharge pipe to prevent animals and rodents
from entering the discharge pipe.
Control Panel
One control panel will be installed with this wastewater system. This panel will control operation of
the re-circulation pump and UV system. If desired, this panel can be connected to a land based
phone line that will notify the operator of system operation.

PVC Riser Installation
Installing PVC Access Risers onto Cast-In Orenco® Riser-Tank Adapters
Access risers provide access to septic tank openings,simplifying inspection and maintenance procedures.Access riser-to-tank connections
must be watertight for the proper functioning of an onsite septic system or effluent sewer system. Orenco strongly recommends watertightness
testing of all access riser-to-tank connections after installation.
Following are instruction sets for prepping and installing access risers, installing grommets,and selecting adhesives for riser installations.
Refer to the chart below to determine which instruction set to use.

Instruction Set 1: Riser Preparation
Step 1:Determine Riser Height
0 Determine riser height
Determine how high the riser needs to be.
• The top of the riser should be about 3 inches(75 mm)above finished grade 3 inches(75 mm)
after installation and backfilling—This allows 2 inches(50 mm)for tank 13 r
settling and 1 inch (25 mm)for ensuring drainage away from the riser. ��O .c
Step 2:Cut Riser to Size(if Necessary) o •o G •
If the riser needs to be cut to size, cut it with a circular saw or table saw. oo�'° d, • •.•.•

n•
• To install risers less than 30 inches (760 mm) wide onto 500-gallon
(2000-L) Orenco FRP tanks, cut the riser so it fits into the tank and the
lowest rib rests on the tank's top, as shown.
Step 3:Dry Fit Riser to Adapter
Step 3a: Dry fit the riser to the adapter.
I 1 '
• Make sure riser penetrations are the right sizes and in the correct locations. 1 `• 1
Step 3b: If the riser is higher than 3 inches (75 mm) above the estimated final
grade,cut it to size per the instructions in Step 2.
Step 3c: If the riser is too short, use an Orenco grade ring to extend it. Riser prep for 500-gal.(2000-L)Orenco FRP tanks

tions)for wait times before inspecting the tank for leaks.
• Orenco recommends at least 30 minutes for its fiberglass tanks.
Step 2b: Check for any drop in the liquid level inside of the riser and any visible
leakage from the riser-to-tank connections.
• At the end of the test,there should be no drop in liquid level and no visible
leakage from seams,pinholes, or other imperfections.
• If leaks are found during the test, seal the leaks and repeat the test.
Step 2c: Once the riser-to-tank connections are proven watertight, remove the
plug(s) and drop the water level in the tank to just below the invert of the inlet or
outlet,whichever is lower.

Septic Tanks Used in AX-RT Treatment Systems
Be sure that any septic tank used in an AX-RT Treatment System meets the following conditions:
• The tank must conform to an approved and authorized tank design for AdvanTex Systems, and it must meet all applicable regula-
tory requirements (no pour-in-place tanks,no homemade tanks, etc.). Call your local Dealer for specifics.
•The tank must be structurally sound.
• The tank must have at least 1000 gal. (3800 L) capacity for an AX20-RT, 1250 gal. (4730 L)for a 5-bedroom AX25-RT, and 1500
gal. (5680 L)for a 6-bedroom AX25-RT at the normal operating level (below the invert of the outlet).
• The tank must have an at-grade access with a watertight, securable and removable lid. If it doesn't,an at-grade access must be
installed onto the septic tank and be made watertight.
• The tank must be watertight and free of leaks.
•An Orenco effluent filter(model FTS0444-36V, FTW0444-36V, or FT0822-14B) must be installed in the septic tank.
AKey Point:For existing septic tanks—the tank's depth of burial must allow for a minimum fall of 1/8 inch per foot(10 mm
per meter or 1%) from the septic tank's invert of outlet to the AX-RT unit's invert of the inlet. If sufficient fall cannot be met, a
grade ring extension must be installed on the AX-RT or a pumping system will need to be installed in the septic tank to move
the filtered effluent to the AX-RT unit. (Contact your Dealer for assistance.) i

Raw sewage enters the septic tank through its inlet tee. In the septic tank,the raw sewage separates into a scum layer,a sludge layer,
and a clear zone. Effluent from the clear zone passes through a Biotube®Effluent Filter and is discharged to the recirc/blend chamber
of the AX-RT unit.The effluent flows through the recirc transfer line to the recirc pumping system,which pumps filtered effluent to the
distribution manifold in the top of the unit. Effluent percolates down through the textile media and is divided—by means of a tank baffle
—between the recirc/blend chamber and the recirc/filtrate chamber inside of the unit.
The recirc pumping system's operation is controlled by a timer in the control panel. It allows the pump to dose the textile media for short
periods (usually 40-60 seconds),typically 72 times a day.These frequent"micro-doses,"which optimize the treatment process,occur
throughout the day to maintain the proper biological environment.

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,orTDF),providing a graphical representation of a pump's optimal performance range.Pumps perform best at their nominal flow rate.These
graphs show optimal pump operation ranges with a solid line and show flow rates outside of these ranges with a dashed line.For the most accurate
pump specification,use Orenco's PumpSelecf software.

Step 4:
© Check the float settings with the project plans and specifications. If the set-
tings need to be adjusted,loosen the set screw as described in step 3.
Adjust the float switches to the desired level and tighten the set screw.
' Make sure float level settings do not violate any state or local regulations.
Note: The float stem provided is the maximum length possible without
l� interfering with the pump minimum liquid level or screened pump vault
intake ports. Never lengthen the float stem without prior approval from

float cables,and do not try to thread the markers and tag through the ® ,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.

Maintenance Instructions
Orenco 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 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.
