RE: Application for Discharge System—Beridze Property NCDEQIDWRINPDES
226 Smith Drive, Durham,NC 27712
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 will serve an existing a 3-Bedroom Single Family
Residence (SFR) located in Durham County, North Carolina. The proposed system will replace
the unpermitted system that 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 topography and/or landscape position, unsuitable soil
characteristics, unsuitable wetness conditions, and inadequate depth of soil. The proposed
system is to be sized for 3 bedrooms at 360 gallons/day.
This application is being submitted with the intent to have coverage under the NCG55 General
Permit. Coverage under this permit is sought to replace an unpermitted sand filter system.
The following information is included with this letter:
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.
Letter requesting Authorization to Construct. Attachment D.

The discharge point is in an existing surface drainage ditch on the southwest corner of the
property that will flow south into an existing pond and east into a tributary to Cabin
Branch. 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 existing surface drainage ditch on the
southwest corner of the property. This roadside ditch flows south into an existing
pond and then east into an unnamed tributary to Cabin Branch, the Blue Line
Feature. This flow path serves is currently utilized by the existing, permitted
discharge system on the adjacent property (230 Smith Dr—NCG551521). 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.
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. Ms. Laura
Adcock, Engineering Services Supervisor of the Durham Public Works Department,
indicated that the property is not within the city's coverage area. The closest current city
maintained sewer is approximately 1,850 linear ft. from the property and there are no
immediate plans for a sewer extension to the area at this time (Attachment H). For
reference, if an installation cost of$100/ft of installed sewer line was assumed,the cost to
connect this property to the sewer line would be approximately$185,000.

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 August 1,
2017 (Attachment B). The letter indicated that a permit cannot be issued due to
unsuitable soil topography and/or landscape position, unsuitable soil characteristics,
unsuitable wetness conditions,and inadequate depth of soil.
Investigate Land Application such as spray irrigation or drip irrigation.
Per the soil evaluation by Chris McGee of Agri-Waste Technology, Inc. the site does not
have sufficient space or suitable soil characteristics to accommodate a non-discharge
surface spray or drip wastewater system(Attachment 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 existing pond and tributary to Cabin Branch.
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
- No suitable soil for a subsurface absorption system.
c.) single-family residence wastewater irrigation (drip and spray)
- Unsuitable soil and insufficient space for a non-discharge
ground absorption system.
d.) reclaimed-water systems
- No suitable soil for a reclaimed water system. No
reasonable ability to operate as a bulk distributor of
reclaimed water.
e) Any viable combination of the above
- There are no viable combinations of the above due to soil
and cost limitations.

Local Government Review Forms
As part of the EAA, Local Government Review Forms were sent to Durham County and
the City of Durham. A copy of the submittal is included as Attachment J. To date, the
completed forms have not been received.

Dear Tamar Beridze:
The Durham County Health Department has determined the above referenced property is
served by a discharging sandfilter sewage. The site characteristics identified on the
property do not meet the requirements of 15A NCAC Section .1900,therefore,no permits
may be issued to convert the existing sandfilter system to ground absorption sewage
disposal system. Municipal sewer is not available to the property as of February 13,
2020.

Re: Application for improvement permit for: Tamar Beridze
Property site: 226 Smith Drive
Environmental Health Division file number:304499
Dear Tamar Beridze,
The Durham County Department of Public Health, Environmental Health Division on 2/12/2020
evaluated the above referenced property at the site designated on the plat/site plan that
accompanied your improvement permit application. According to your application the site is
to serve a 4 bedroom residence with a design wastewater flow of 480 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 improvement permit. 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)
riUnsuitable soil characteristics (structure or clay mineralogy)(Rule .1941)
©Unsuitable soil wetness condition (Rule .1942)
IPIUnsuitable soil depth(Rule .1943)
III"resence of restrictive horizon (Rule .1944)
IIIInsufficient space for septic system and repair area (Rule .1945)
III1Unsuitable for meeting required setbacks(Rule .1950)
III•ther(Rule .1946)
These severe soil or site limitations could cause premature system failure, leading to the
discharge of untreated sewage on the ground surface, into surface waters, directly to ground
water or inside your structure.
The site evaluation included consideration of possible site modifications, as well as use of
modified, innovative, or alternative systems. However, the Health Department has determined
that none of the above options will overcome the severe conditions on this site. A possible
option might be a system designed to dispose of sewage to another area of suitable soil or off-
site to additional property.
For the reasons set out above, the property is currently classified UNSUITABLE, and no
improvement permit shall be issued for this site in accordance with Rule .1948(c).

Note that a site classified as UNSUITABLE may be classified as PROVISIONALLY SUITABLE if
written documentation is provided that meets the requirements of Rule .1948(d). A copy of this
rule is enclosed. You may hire a consultant to assist you if you wish to try to develop a plan
under which your site could be reclassified as PROVISIONALLY SUITABLE.
Youhave a right to an informal review of this decision. You mayrequest an informal review
a e g q 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

MEMORANDUM
TO: Mr.Andres Rivera
FROM: Chris McGee,LSS
SUBJECT: Soils Evaluation for 226 Smith 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 property in Durham, NC. The
evaluation was performed by Alex Thompson and supervised by Chris McGee of AWT on April
23, 2020. A single-family residence with an unpermitted wastewater system is located at 226
Smith Drive. The property has been deemed unsuitable for subsurface wastewater systems by
the Durham County Environmental Health Department.
The soils on the subject property are unsuitable for subsurface and surface application
wastewater systems due to shallow wetness conditions, shallow depth to expansive clay
mineralogy, and insufficient space. Therefore, the property does not comply with the
requirements of 15A NCAC 18A Section .1900 — Sewage Treatment and Disposal Systems -or-
15A NCAC 02T Section .0600 — SFR Wastewater Irrigation Systems. The site is a likely
candidate for a surface water discharge system.
Please contact us with any questions,concerns,or comments.

Subject:USGS response to DWR USGS Low Flows request#2020-55 (dated 2020/03/04)for UT Cabin Branch Durham
County...Re: Low-flow request approval
Ms. Davidson,
In response to your inquiry about the 7Q10 low-flow characteristic for an unnamed tributary within the
Cabin Branch basin in vicinity of Durham in north 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
(36.101, -78.903) provided via email dated 03/04/2020 from the DWR USGS Low Flow portal following your
request submission.
FOR THE RECORD: Information provided as part of this request indicates the point of interest to be a ditch
(ephemeral channel) upstream from a small pond feature (not visible on USGS 7.5-min quad map) located
adjacent to the eastern end of Lin Tilley Road, south of Smith Drive, and north of Barclay Road. Existence of
the pond feature was confirmed with visual examination of aerial images available via online sources.
1 of 4 5/19/2020,8:38 AM

USGS response to DWR USGS Low Flows request#2020-60(dated...
No USGS discharge records are likewise known to exist for the point of interest.
In the absence of site-specific discharge records sufficient for a low-flow analysis, estimates of low-flow
characteristics at ungaged locations are determined by assessing a range in the low-flow yields (expressed as
flow per square mile drainage area,or cfsm) at nearby sites where estimates have been determined.
A basin delineation completed using the online USGS StreamStats application for North Carolina
(https://streamstats.usgs.gov/ss/) indicates the drainage area for the point of interest(StreamStats adjusted
coordinates 36.10030, -78.90336 NAD83) is just slightly less than 0.01 sqmi.
For streams in north central Durham County, low-flow characteristics published by the USGS are provided
in the following reports:
(1)The first is a basin-wide report for the Neuse River basin published in 1998. It is USGS Water-Resources
Investigations Report 98-4135, "Low-flow characteristics and discharge profiles for selected streams in the
Neuse River basin, North Carolina" (Weaver, 1998). The report is available online at http://pubs.usgs.gov
/wri/1998/4135/report.pdf. This report provides low-flow characteristics(based on data through 1996)for
USGS continuous-and partial-record sites in the Neuse River basin where sufficient data was available for
analyses. However,the report does not provide statistical relations for estimating low-flow characteristics at
ungaged locations.
(2)The second is a statewide report published in March 2015. It is USGS Scientific Investigations Report
2015-5001, "Low-flow characteristics and flow-duration statistics for selected USGS continuous-record
streamgaging stations in North Carolina through 2012" (Weaver, 2015). The report is available online at
http://pubs.usgs.gov/sir/2015f 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 an extremely 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 just slightly less than 0.01 sqmi.
On pages 33-34 of the Neuse basin-wide low-flow report (first reference above) is information about the
Occurrence of Zero or Minimal 7Q10 Discharge that is likely to occur for a stream within the major basin,
contingent on the size of the upstream drainage basin. The discussion on page 33 in this section indicates
that poorly drained soils(that is, soils having low infiltration rates) is a primary factor in numerous
occurrences of zero 7Q10 discharges in the upper end of the study area [Neuse River basin]:
"Much of the water that comes in contact with the soils in this area most likely enters the streams as
overland runoff and does not infiltrate into surficial aquifers for later release during drought conditions.
Among sites having zero 7Q10 discharges, the drainage areas range from less than 0.01 mi2 (site 10)to
about 44 mi2 (site 121). For sites in this area having non-zero 7Q10 discharges, the average 7Q10 unit low
flow is about 0.005 (ft3/s)/mi2. Therefore, sites with drainage areas less than about 10 mi2 could be
expected to have zero or minimal 7Q10 discharges (less than 0.05 ft3/s)."
Additionally,the basin upstream from the point of interest is underlain by the Triassic basin geologic unit.
2 of 4 5/19/2020,8:38 AM

USGS response to DWR USGS Low Flows request#2020-60(dated...
From a hydrologic perspective, streams underlain by this geologic unit have very little to no potentials for
sustained base flows during extended dry periods. At sites underlain by the Triassic basin where the USGS
has collected sufficient records for low-flow analyses,the low-flow characteristics for sites having
drainageareas that would typically be expected to have sustained flows actually have some of the lowest
low-flow estimates in the state.
Consideration of the above information results in a conclusion the 7Q10 discharge for the point of interest is
zero flow.
Please understand the information provided in this message is based on a preliminary assessment and
considered provisional, subject to revision pending further analyses.
This low-flow response is provided via the DWR USGS Low Flows cooperative agreement between the USGS
and the N.C. Department of Environmental Quality, Division of Water Resources.
Hope this information is helpful.
Thank you.

Hi Scott,
The closest City sewer is approximately 1850 feet to the southwest(circled in red in the below screenshot(.However,as you can see,topography would not allow a gravity feed from this property into that sewer main.
I am not aware of any plans to extend sewer in the immediate area of 226 Smith Rd.

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 existing
drainage ditch in the southwest corner of the property. Effluent leads south in the ditch to an existing pond and
empties to the east into a tributary to Cabin Branch. 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 existing drainage ditch located on the southwest corner of
the property, which leads to a tributary to Cabin Branch. 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.

Contact Person: Scott Jones,P.E.
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. Ms.Laura Adcock,Engineering Services
Supervisor of the Durham Public Works Department, indicated that the property is not within the city's coverage
area. The closest current city maintained sewer is approximately 1,850 linear ft. from the property and there are
EAA Guidance Document Revision:April 2014
Page 2 of 8

no immediate plans for a sewer extension to the area at this time(Attachment H). For reference,if an installation
cost of$100/ft of installed sewer line was assumed,the cost to connect this property to the sewer line would be
approximately $185,000. Additional costs including the cost of the pump station,potential "tap"or sewer capital
fees,road repair costs,frontage fees and fees for right of way permits would also be incurred by the homeowner.
(b) Provide a preliminary indication of flow acceptance from existing municipal or private
WWTPs under consideration for connection. If a municipal or private WWTP cannot accept
the wastewater, include a letter documenting such and consider this alternative
technologically infeasible.
Response: N/A No sewerage available
(c) If an existing sewerage system will accept the wastewater, evaluate the
piping/pumps/resources necessary to connect to the existing wastewater treatment plant.
Attach a topographic map or a site drawing showing the physical route of this alternative.
Conduct a Present Value Cost Analysis per STEP 4.
Response: N/A No sewerage available
2. Planned Sewerage System: Determine if a regional sewerage system within a five mile radius is
projected to be available within the next five years to receive waste from the project site. If
applicable, determine availability date and flow acceptance projection from appropriate
authority.
Response: As stated above,the City of Durham's sewerage system currently exists within five miles of the property,but a
connection to this system is infeasible due to the cost. According to the Durham Public Works Department,there
are no known plans to bring the city sewer system closer to the applicant's property.
Alternative B. Land Application.
Land application disposal alternatives include individual/community onsite subsurface systems, drip
irrigation,and spray irrigation.
1. Provide an estimate of the best case hydraulic loading rate based on County Soil Surveys or from
a soil evaluation performed by a soil scientist. Include calculations showing the hydraulic
loading rate and the total area of land needed for the land disposal system,including buffers.
Response: The Durham CountyEnvironmental Health Department indicated that the site is unsuitable for installation of a
P P
ground absorption septic system in a letter dated February 13,2020(Attachment B of application package). The
letter indicated that a repair permit cannot be issued due to unsuitable soil characteristics and insufficient space.
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 Mayodan series soil. For a subsurface system in this soil,a drip system with pretreatment would
be required. This Mayodan soil is a sandy loam soil that would have a long-term acceptance rate (LTAR)
ranging from 0.05-0.2 gpd/sq.ft., with a typical rate of 0.1 gpd/sq.ft. Subsurface systems also require the
drainline to be installed with the contour so that each drainline is at a constant elevation. This results in a
"fanning"of the drainline and requires additional space in order to install the required amount of drainline. The
sizing calculation is summarized in the table below:
EAA Guidance Document Revision:April 2014
Page 3 of 8

Subsurface Dripfield Design Alternative
#Bedrooms 3
Daily Flow 360 gpd = 120 gpd*#bedrooms
LTAR 0.1 gpd/sqft
Minimum Area Required (Nominal) 3,600 sqft =Daily Flow/LTAR
Estimation for Topographical Variation 1,200 sqft
Estimated Area Required (Actual) 4,800 sqft
Approximate Area Available 5,076 sqft
The current property's land available for the system is 5,076 sqft, due to setbacks and existing site conditions.
This area also considers maintaining a 50' well setback. A schematic of this area is shown in Appendix A of
the EAA. The land needed for a subsurface dripfield design is a minimum of 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 Mayodan soil. For a surface system in this soil,the SFR loading
rate group is likely restricted to a maximum annual loading of 19.5 in/year. The sizing calculation for a non-
discharge surface system is summarized in the table below:
Non-Discharge Surface Design Alternative
#Bedrooms 3
Daily Flow 360 gpd = 120 gpd*#bedrooms
Surface Loading Rate 19.5 in/year
Minimum Area Required (Nominal) 10,810 sqft
Approximate Area Available 3,530 sqft
The current property's land available for a surface drip or spray system is 3,530 sqft, due to setbacks and
existing site conditions. A schematic of this area is shown in Appendix A. The land needed for a non-
discharge application system is estimated at 10,810 sq.ft.,so there is insufficient space at this residence. The
potential waving of property setbacks was taken into account when considering the available application area
for both surface systems.
2. Assess the availability of land. If insufficient land is available onsite, assume that the necessary
land can be purchased and estimate the land purchase cost based on local real estate prices.
Alternatively,provide documentation to demonstrate that insufficient land is available for sale in
the project area (include letters from adjacent property owners indicating no interest in selling
property).
Response: Because insufficient land is available onsite, offsite land was reviewed. The table below lists neighboring
properties and the value of the land as listed by the Durham County GIS website. The 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 Mayodan. These sites will be very restrictive for
wastewater systems.

3. Provide a description of the wastewater treatment system and the non-discharge application
system. Include a site plan showing the proposed layout, the application area, any existing
structures,proposed structures,and other uses within the site.
Response: A typical subsurface drip system or a non-discharge surface spray or surface drip system with pretreatment
considers the following components:
-Septic Tank with Effluent Filter
-Recirculation Tank(Integrated in AX20-RT unit)
-AdvanTex Treatment Pod(AX20-RT unit)
-Pump Tank(potentially integrated in AX20-RT unit)
-UV Disinfection(Integrated in AX20-RT unit)
-Headworks Box
-Control Panel
-Disposal Field(drip or spray)
Note:The proposed discharge system does not consider the pump tank,headworks box or disposal field.
Site drawings of these alternative systems showing the available application area are included as Appendix A
of the EAA. Due to the size requirements of a drip or spray system and the limited available space,there is no
ability to consider any of these systems on this property.
4. Explain the proposed reuse plan if reclaimed water will be used by a third party.
Response: There is no reuse plan being considered either on-site or by a third party. The existing residential plumbing
infrastructure does not allow for reuse in the existing residence. It is not feasible to consider using reclaimed
water on the site or becoming a bulk distributor of reclaimed water. The table below summarizes the
amount of reclaimed water that could be beneficially used on site. As shown,there is insufficient area to
utilize the daily flow of reclaimed water.
On-site Utilization of Reclaimed Water
Daily flow through system 360 gpd
Available Area to Irrigate 5,650 sgft *Veg. cover on property
Application Rate 0.5 in/week Fescue Grass
Acceptable Volume to Irrigate 235 ft3/week_
= 252 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.
EAA Guidance Document Revision:April 2014
Page 5 of 8

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

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.
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—Beridze Property
226 Smith Drive,Durham,NC 2712
Dear Mr.Bonfield
Enclosed please find a Local Government Review Form required for a Certificate of
Coverage application supporting a proposed wastewater treatment system. The proposed
system will be permitted under the NCG550000 General Discharge Permit for Single Family
Residences. The proposed system will serve an existing 3-Bedroom Single Family residence
(SFR) located in Durham County, North Carolina. The proposed system will replace the
unpermitted discharge system that currently serves the residence.
The site has been deemed unsuitable for ground absorption sewage treatment systems by the
Durham County Environmental Health Department. It is my opinion that a wastewater
treatment system covered by the General Discharge is the only technology and economical
feasible option for this residence.
Will you please complete the enclosed form for inclusion in the application for the proposed
system. This residence is located in Durham County and is 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.

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 be 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 bums 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 existing drainage ditch located on the southwest 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.

Area of Riser Openings= 6.28 ft^2
Tank Weight(est.)= 11,000 lb. (based on manufacturer)
Buoyancy Force Calculation:
Buoyancy Force=Specific Weight of Water x Displaced Volume
Buoyancy Force= 18,468 lb.
Weight Calculation:
Tank Weight= 11,000 lb
Water Weight in Tank= 0 lb
Soil Weight Over Tank= 4,015 lb
Soil Tension Force= 4,058 lb
Total Weight= 19,073 lb
Note: Total weight must be greater than buoyancy force
so that tank will not float during high water table conditions.

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

About Adhesives
ADH100 is a single-component adhesive/sealant for sealing pipe grom-
mets and joining PVC or fiberglass risers to ABS or fiberglass PRTA-
O�. r style tank adapters(where the joint is in shear). Handling strength is
or MIN I �„ achieved within 12 hours,and full cure in 2 to 3 days.It comes in a
r/ I 10.2-oz(300-mL)cartridge tube for application with a caulking gun.
ADH1011PS810)adhesive is a white,two-component,self-leveling
_`4 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
MA
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.

'1 Instruction Set 2: Cast-In Adapters
` Adapter type used: PRTA24 or PRTA30
Adhesive used: ADH100,MA320,SS115,or SS140
Bolt-down kit used: None
Step 2a:Apply Adhesive
Apply adhesive to the outside surface of the riser tank adapter.
Hint: If you plan to backfill the same day,the use of MA320,SS115 or
SS140 adhesive is recommended because of their quicker cure times.
Cast-in PRTA30 tank adapter If you have multiple riser installations and do not have bulk adhesive
(SS115/SS140),consider using both MA320 and ADH100.Apply just
°' enough MA320 on the outside of the tank adapter for a quick structural
®'` y joint(cure time is typically less than an hour).A single package of
44 MA320 can be used to provide a structural joint on two or three risers.
Then apply ADH100 to the inside of the adapter and the riser joint,for a
watertight seal.
Step 2b: Place Riser
116 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.
1,, . Step 2d: Cure Adhesive
IP Allow adhesive to harden before backfilling.For ADH100,handling
strength is typically achieved within 12 hours.For MA320,cure time is
achieved within 30 minutes to 3 hours,depending on temperature.

Step 1: Mark the Riser
assembly To install grommets in the field,first mark the riser for location of the
/L 4y grommets.(For Perma-Loc risers,you should try to avoid
Grommet cutting through the pipe seam—the extra thick rib—unless it is
(at 3 o'clock) unavoidable.)

^, "# e
,.., 4„: , ,; Step 3: Remove the Ribs
Using a hammer and chisel,break the notched ribs from the riser.Use a
grinder to remove any remaining rib material so that you are left with a
smooth area,ensuring a watertight fit.(Hole saws with attached pocket
cutters are available from Orenco;they cut away the ribs as the hole is
cut,eliminating the need to notch and break the ribs.)
:.©
• 1 - Step 4: Cut the Hole
f Using the Grommet Hole Saw Sizing Chart below,select a hole saw
for the grommet installation and drill out the opening.(If you are using
pipe and grommets other than U.S.nominal sizes,ascertain the correct
hole size for your grommet.)Use a deburring tool or knife to deburr the
edges of the opening,being careful not to enlarge the

Septic Tanks Used in AX-RT'f a �g, ux
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.)

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.

•The bottom of the AX-RT lid must sit 2 inches(50 mm) above finished
Lower the AX-RT unit into position. grade when set and level.
•If the AX-RT unit is installed in its own excavation,the unit requires
18-24 inches (457-610 mm)of space on all four sides.
•If the AX-RT unit is installed in tandem with the septic tank,a minimum of
2 ft(610 mm)separation distance is required between the unit and tank.
•If the AX-RT unit is being installed parallel to the septic tank,offset the
unit from the tank by 6 ft(1.8 m) if antibuoyancy measures are neces-
sary or 4 ft(1.2 m) if antibuoyancy measures are not necessary.
_ Step 5:Install Antibuoyancy Deadmen (If Needed)
®' ,r j ltli Determine if antibuoyancy deadmen are necessary for the installation.
Lip- pi Orenco offers antibuoyancy hardware kits that can be used with Orenco
if i fiberglass deadmen or concrete deadmen.
jail • Deadmen are recommended for all installations.

I. . • Deadmen are required if there is a potential for groundwater to be pres-
18-24 in. ent in the excavation at any time,or if surface runoff can fill the excava-
(460-600 mm) tion at any time,resulting in a"bathtub"effect.
oTcANote:This effect occurs in dense soils when water fills an excavation
during surface water runoff—usually during a heavy rain event—
before the disturbed soil in the excavation has had time to settle.
\I • If you are unsure whether to install antibuoyancy deadmen or not, con-
sult the system Designer or an engineer.

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
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.

Maintenance Instructions
Manes 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.
