Dear Ms. Wilson:
Attached are the originals plus three (3) copies of each of the local govemment review forms received for
the following listed applications for NPDES permits previously submitted by Aqua North Carolina, Inc.
These are for the following facilities:
I. Colonial Woods Subdivision (Well # I and Well # 2)
!
2. Bannertown Hills Subdivision X
3. The Hollows Subdivision —a " 000 YYY - '
4. Reeves Woods Subdivision
5. Hillcrest Subdivision — VIt.C/Ylui/
6. Snow Hill Subdivision /�IQAO r
7. Windgate Subdivision
These are all existing groundwater wells that filter water through a series of green sand filters. The filters
are "backwashed" and water is then discharged into the nearby stream.
These local government review forms are being forwarded even though these are not discharges of
domestic type wastewater and, hence, the statutory requirement for local government review is not
applicable. It is my understanding from conversation with Mr. Agyeman Adu-Poku that the processing of
the applications is proceeding.
We appreciate your consideration of our applications for permits. If you have any questions or if there is
anything we can do to assist, please call me(704-788-4455.)

Subject: Request for Local Government Review
NPDES Permit Application
Existing Well Backwash Discharge
Snow Hill Subdivision
Surry County
Dear Mr. Sammons:
Attached is a copy of an application for permit signed by Aqua North Carolina, Inc. This
application is for a permit for the continued discharge of backwash from filters installed on an
existing potable well which serves the Snow Hill Subdivision, located outside Dobson off Snow
Hill Drive. 1 have also attached a map to indicate the existing location.
As part of the application process, the state requires that we notify the local government and ask
that they complete the attached form which indicates whether the local government has a zoning
or subdivision ordinance and whether the continued discharge is consistent with that ordinance.
This is an existing groundwater well that filters water through a series of filters before the water
is distributed to the Snow Hill community. The filters are "backwashed" with water
approximately once every two days and approximately 2,520 gallons of water is then discharged
in to the nearby stream.
This has been in service for a number of years and we are not aware of any environmental
concerns over this discharge, other than that the state has advised that we must apply for a
permit.
As the state has instructed, we are trying to file this application as soon as possible. If you could
complete, sign and return this form, it will be very helpful.
We apologize for the necessity to ask for this assistance but I hope that you can appreciate our
dilemma. If you have any questions or if there is anything we need to discuss, please call me
(704-788-4455.)

Dear Ms. Wilson:
Attached are four(4) copies of the application for NPDES permit signed by Aqua North
Carolina, Inc., four(4) copies of the Engineering Alternatives Analysis (EAA) and a check for
$ 715 (application fee.)This application is for a permit for the continued discharge of backwash
from existing green sand filters installed on a potable well which serves Snow Hill Subdivision,
located outside Dobson, N.C. The EAA contains maps which indicate the existing location.
This is an existing groundwater well that filters water through a series of green sand filters before
the water is distributed to the Snow Hill community. The filters are "backwashed" with water
approximately once every two days and approximately 2,520 gallons of water is then discharged
into the nearby stream.
This well has been in service for a number of years and we are not aware of any environmental
concerns over this discharge.
We appreciate your consideration of our application for permit. If you have any questions or if
there is anything we need to discuss, please call me (704-788-4455.)

Section 1: General
' 1.01 Introduction:
Aqua North Carolina, Inc. (Aqua NC) currently owns and operates an existing well
water system serving Snow Hill Subdivision (Snow Hill), located southeast of
Dobson, N.C. in Surry County. Well #1 of the water system uses an assembly of
p four (4) green sand filters in the treatment of groundwater prior to distribution to
the Snow Hill community. These filters are backwashed, using potable water,
approximately once every two (2) days. This backwash is a relatively small volume
of approximately 2,520 gallons. The discharge leaves the well house via a 2"
plastic pipe, and is released into an intermittent stream that is an unnamed
tributary to Cody Creek in the Yadkin River basin.
The well has a good overall history of compliance with water supply regulations,
but is required to obtain an NPDES permit for the continued operation of the
existing backwash discharge.
The Snow Hill water system currently has 29 customers. Well # 1 is approved for
45 gpm. No expansion of the capacity of this well is planned and the system is
sufficient to serve the subdivision. Whereas the subdivision is fully developed and
e since no expansion of the subdivision or service area is planned, there is no
potential for any substantial population increase to affect the existing rate of water
use or backwash discharge flow (2,520 gallons/two days.)
The review of this source and the consideration of alternatives is being made with
inclusion of consideration of the guidance contained in "Permitting Strategy For
Greensand Filtration Water Treatment Plants - January 2004")
1.02 Scope:
' The scope of this project is limited to the investigation and evaluation of
alternatives for treating and/or disposing of the existing green sand filter backwash
e from Well # 1 at Snow Hill Subdivision. This includes consideration of the feasibility
of continuing the existing discharge and options for eliminating the existing
discharge.
Section 2: Background Information
2.01 Project Area:
The existing service area is limited to Snow Hill Subdivision. All homes are single
family residences. There are no commercial or industrial customers. All
wastewater is typical backwash from green sand filters.
' The existing discharge coordinates are: Longitude: -80 deg. 42 min. 37 sec. W
Latitude: 36 deg. 21 min. 06 sec. N

1 4
2.02 Site Characteristics:
' The subdivision is located in a rural portion of Surry county, outside any municipal
limits and remote from public water and/or sewer. The nearest existing sewer is
approximately 1.9 miles away.
The general area has soil characteristics which are limited to the possibility of on
esite treatment and disposal.
Terrain is generally rolling but has been graded level at the existing well site.
2.03 Receiving Stream Characteristics:
The receiving stream is intermittent in nature and is an unnamed tributary to Cody
Creek, which is class C waters. The receiving stream is obviously a zero flow
stream (7Q10 and 30Q2 = 0) but since the wastewater discharge is not oxygen
consuming, discharge into the zero flow stream should be allowable under state
procedures.
This receiving stream has no known outstanding features or characteristics that
should preclude the continuation of the existing discharge. There are no known
endangered or threatened species and these are not threatened or impaired
ewaters.
Section 3: Existing Utilities
3.01 Public Facilities:
' The nearest existing public sewer is located approximately 1.9 miles northwest of
the existing well near the junction of Windsor Park Drive and South Main Street
' (Business 601) at the southern border of the Town of Dobson city limits. The
distance that would be required for sewer force mains to be installed would be
approximately 10,000 ft. This would be the route that appears to be the most
practical from an engineering perspective to take advantage of following existing
highway right of way and have minimal impact to adjacent property owners.
The Town of Dobson, Public Works Department provides sewer services in this
area. The Town Manager's office was consulted and has advised that there are no
established plans for extension of sewer service any closer to the Snow Hill
Subdivision within the next ten years or beyond.
3.02 Private Facilities:
' There are no known existing private sewer utilities within any reasonable proximity
of the Snow Hill Subdivision that would be available for consideration as a possible
alternative. A review of available records did not reveal that there are any private
sewer facilities within a two mile radius.

' 5
Section 4: Alternatives For Service
4.01: On site surface and/or subsurface disposal:
Subsurface Disposal:
e Appendix E contains portions of soil survey reports that provide insight as to the
suitability of the soils for subsurface disposal. As described in the report, these
soils are mainly Fairview soils with characteristics that are somewhat limited to
1 very limiting with respect to the potential for subsurface disposal. In addition to
researching the information available from NRCS soils maps, the engineer
consulted with Mr. Johnny E. Easter, IRS, Surry County Environmental Health
e Director concerning the possibilities of subsurface disposal. Mr. Easter suggested
that, for purposes of evaluating this based on the limited information available, an
application rate of 0.25 gpd/SF would be a reasonable assumption. Of course,
before a final design and/or approval could be given, an actual on site soils
evaluation would be required. For the purposes of evaluating this as a possible
' option, a design application rate of 0.25 gpd/SF will be used.
Subsurface disposal requires buffers and land for the drainfields as well as equal
areas of suitable soil, be available and maintained as potential repair/replacement
areas.
Aqua North Carolina only owns a 1.00 acre lot around the well. Whereas the well
must have a 100 foot buffer to any disposal site, this would necessitate that Aqua
North Carolina acquire additional property to allow for the possible subsurface
' disposal site, repair/reserve area and buffers. The owner of the nearest properties
surrounding the well site has expressed that he is unwilling to sell or allow any of
his lands to be used for any purposes. Hence, the evaluation of potential sites has
excluded these properties and looks at the potential of the next closest properties.
Given the limitations described in the attached soil survey and discussed above, it
is doubtful that this is a viable option. A full and extensive soils investigation of
potential sites would be necessary to confirm if useable areas are available. In
keeping with the state guidance for alternatives evaluation, the cost effectiveness
of this alternative is further evaluated to determine if a detailed soils analysis is
appropriate. The costs associated with this option are estimated in Appendix A.
This option would require that the existing discharge be conveyed to an acquired
site having sufficient area for subsurface disposal and a suitable reserve area of
equal size, and that these areas include adequate buffers from property lines,
homes, wells, etc.
Surface Irrigation:

' 6
tDisposal by irrigation requires storage capacity for periods of inclement weather
when application is not allowable. Therefore consideration of this as a possible
alternative must also include the provision of storage of the backwash waters
during periods of inclement weather.
As noted earlier, the soil surveys for this area have determined this to have limited
to severely limited potential for on site subsurface disposal. Consideration of this
alternative is based on an assumed allowable application rate of 0.20 inches per
week which is based on a typical range of 0.15 to 0.25 inches per week for this
geographic area and the soil conditions generally described in the soils survey.
' Storage requirements for this area are typically in the range of 45 to 90 days. For
purposes of this assessment, a storage requirement of 60 days will be assumed.
Considering the relatively benign nature of the current discharge it is not expected
that any additional treatment would be required for surface application. Although
the additional cost of conveyance and the additional costs for on site disposal
should readily be recognized as a significant cost increase as compared to the
alternative of continued discharge, an estimate of the costs for this alternative is
' included in Appendix A for comparison.
The evaluation is based on a very conservative assumption that the nearest
a available lands that could be reasonably used would actually be available. A
comparison of the costs were made first, using the best (lowest cost) reasonable
assumptions. It would obviously be necessary to perform a more detailed site
investigation and ascertain if the property owner would consider allowing these
lands to be acquired for this purpose.
' 4.02: Wastewater Reuse
Options for reuse of wastewater for this area are essentially nil. Reuse is usually
' associated with non-potable uses such as irrigation. This becomes potentially
more viable if there is a need or outlet for reuse such as irrigation of a golf course.
The volume of this discharge is very low and would have little attraction as a
source for recycle purposes. This area does not have a golf course, nor are there
any other viable options for reuse associated with the subdivision or in the
surrounding area.
4.03: Surface Water Discharge
This is the current method of wastewater disposal. There is no anticipated need to
add any new facilities for additional treatment.
An estimate of the costs for the continuation of this alternative is included in
Appendix A for comparison.

' 7
t4.04: Combination of Alternatives
Alternatives to discharge that may be technologically feasible, such as connection
to the nearest public sewer, subsurface disposal and/or surface irrigation, could
not be employed in conjunction with the current method of disposal (surface water
discharge) and yield any reduction in total capital or operating expenditures. The
evaluation of alternatives shows that these alternatives are clearly not viable due
eto the overwhelming magnitude of associated cost.
Combining one of these alternatives while continuing the periodic discharge, yields
' no reduction in the cost for non-discharge alternatives and merely increases the
overall costs. There would be no reduction in capital costs for any of these
alternatives and the operating costs for combining surface discharge with either of
e the other alternatives would be greater than for any single alternative that might be
selected.
In short, whereas the conclusion that continued surface discharge is the only
viable option due to the overwhelming differential in capital and operating costs,
any addition of an additional alternative would merely make the cost differential
' worse.
Section 5: Summary and Conclusions:
As can be seen from a comparison of the net present value of the various
alternatives, there is a wide difference between the cost estimate of the option of
continuing discharge and options to eliminate the discharge.
' Compared to the cost of the next most cost effective and reliable alternative
(subsurface disposal) the estimated Net Present Value is approximately 1,415 %
greater. This represents a difference of $ 6,305 NPV per customer.
In light of the financial impracticality, it is not necessary to further pursue whether
connection is politically acceptable to the POTW or whether land based disposal
options are workable.
By far, the most practical and cost effective and reasonably practical alternative is
athe continued discharge of the relatively benign filter backwash waters.
Section 6: Proposed Wastewater Treatment Facilities:
Based on the findings of this evaluation, it has been concluded that the most
economical and practical alternative is to continue discharge to surface waters.

3. Land Based Disposal:
3A. Subsurface Disposal:
Based on the soil survey information and the engineers field observations, the soils in this
area appear to be limited to severely limited as a medium for subsurface disposal. In the
event that it was found to be apparently a cost effective alternative, an in depth site
0 specific soil investigation would need to be done to confirm that the soils could in fact be
used. However, for the purpose of comparing the potential alternatives within the scope
of this evaluation, it will be assumed that a typical low design loading rate would be
' workable. Therefore, it will be assumed that a loading rate of 0.25 gpd/sq. ft. is
acceptable.
BTherefore, based on the design flow, the area required for subsurface disposal is:
2,520 gpd / 0.25 gpd/sq. ft.= 10,080 Sr-
Whereas it is required to maintain an equal size area as a reserve for future repair, the
' required area is 20,160 SF. Appendix D contains a map, which delineates the area that
might be available for subsurface disposal.
Assuming a roughly rectangular field (150 ft x 135 ft. for the initial drain field plus repair
and In order to maintain the required buffers to property lines, etc.), the minimum
estimated land required is 55,750 SF or 1.4 acres.

3B. Surface Irrigation:
Surface irrigation preliminary design is based on an assumed allowable application rate
of 0.20 gpd/sq. ft. and a required storage basin for 60 days design flow. Based on the
design flow of 2,520 gpd, this results in an estimated disposal area of 12,600 SF.
Allowing a recommended 50% repair area, the required total area is 18,900 SF.
Assuming a roughly rectangular field (125 ft x 150 ft.) for the initial spray field, plus repair
and in order to maintain the required 150 foot buffer to property lines), the minimum
estimated land required is 191,250 SF or approximately 4.4 acres.

' Sewage Disposal
This table shows the degree and kind of soil limitations that affect septic tank absorption fields and sewage
lagoons.The ratings are both verbal and numerical.Rating Gass terms indicate the extent to which the soils are
limited by all of the soil features that affect these uses."Not limited"indicates that the soil has features that are very
favorable for the specified use.Good performance and very low maintenance can be expected."Somewhat limited"
indicates that the soil has features that are moderately favorable for the specified use.The limitations can be
overcome or minimized by special planning,design,or installation.Fair performance and moderate maintenance
can be expected."Very limited"indicates that the soil has one or more features that are unfavorable for the
specified use.The limitations generally cannot be overcome without major soil reclamation,special design,or
expensive installation procedures.Poor performance and high maintenance can be expected.
Numerical ratings in the table indicate the severity of individual limitations.The ratings are shown as decimal
a fractions ranging from 0.01 to 1.00.They indicate gradations between the point at which a soil feature has the
greatest negative impact on the use(1.00)and the point at which the soil feature is not a limitation(0.00).
"Septic tank absorption fields"are areas in which effluent from a septic tank is distributed into the soil through
subsurface tiles or perforated pipe.Only that part of the soil between depths of 24 and 72 inches or between a
depth of 24 inches and a restrictive layer is evaluated.The ratings are based on the soil properties that affect
absorption of the effluent,construction and maintenance of the system,and public health.Saturated hydraulic
conductivity(Ksat),depth to a water table,ponding,depth to bedrock or a cemented pan,and flooding affect
absorption of the effluent.Stones and boulders,ice,and bedrock or a cemented pan interfere with installation.
Subsidence interferes with installation and maintenance.Excessive slope may cause lateral seepage and surfacing
of the effluent in downslope areas.
Some soils are underlain by loose sand and gravel or fractured bedrock at a depth of less than 4 feet below the
distribution lines.In these soils the absorption field may not adequately filter the effluent,particularly when the
system is new.As a result,the ground water may become contaminated.
"Sewage lagoons"are shallow ponds constructed to hold sewage while aerobic bacteria decompose the solid
and liquid wastes.Lagoons should have a nearly level floor surrounded by cut slopes or embankments of
' compacted soil.Nearly impervious soil material for the lagoon floor and sides is required to minimize seepage and
contamination of ground water.Considered in the ratings are slope,saturated hydraulic conductivity(Ksat),depth
to a water table,ponding,depth to bedrock or a cemented pan,flooding,large stones,and content of organic
matter.
e Saturated hydraulic conductivity(Ksat)is a critical property affecting the suitability for sewage lagoons.Most
porous soils eventually become sealed when they are used as sites for sewage lagoons.Until sealing occurs,
however,the hazard of pollution is severe.Soils that have a Ksat rate of more than 14 micrometers per second are
too porous for the proper functioning of sewage lagoons.In these soils,seepage of the effluent can result in
contamination of the ground water.Ground-water contamination is also a hazard if fractured bedrock is within a
depth of 40 inches,if the water table is high enough to raise the level of sewage in the lagoon,or if floodwater
overtops the lagoon.
A high content of organic matter is detrimental to proper functioning of the lagoon because it inhibits aerobic
' activity.Slope,bedrock,and cemented pans can cause construction problems,and large stones can hinder
compaction of the lagoon floor. If the lagoon is to be uniformly deep throughout,the slope must be gentle enough
and the soil material must be thick enough over bedrock or a cemented pan to make land smoothing practical.
' Information in this table is intended for land use planning,for evaluating land use alternatives,and for planning
site investigations prior to design and construction.The information,however,has limitations.For example,
estimates and other data generally apply only to that part of the soil between the surface and a depth of 5 to 7 feet.
Because of the map scale,small areas of different soils may be included within the mapped areas of a specific soil.
The information is not site specific and does not eliminate the need for onsite investigation of the soils or for
testing and analysis by personnel experienced in the design and construction of engineering works.
Government ordinances and regulations that restrict certain land uses or impose specific design criteria were
not considered in preparing the information in this table.Local ordinances and regulations should be considered in
planning,in site selection,and in design.

Residuals Management Plan
Prepared by: J. Thurman Home, P.E.
Horizon Engineering & Consulting, Inc.
Residuals Management Plan:
The proposed continued surface water discharge will have no impact on existing residuals management.
eThere are no wastewater treatment facilities.
The nature of the operation(backwashing of green sand filters) is such that only minor amounts of solids
(less than 30 mg/1) are released with the discharge.
There is no generation of any grits, sludges or residuals for removal or disposal.
' This project does not increase or alter the amounts of sludge produced or impact the current methods of
disposition.
