Attached are four (4) copies of the applications 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 the Bannertown Hills
Subdivision, located outside Mount Airy, 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 Bannertown Hills community. The filters are "backwashed" with
water approximately once every two (2) days and approximately 1,600 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.)
Sincere
orne, P. E.

Section 1: General
p" 1.01 Introduction:
Imt
fir
rol
Aqua North Carolina, Inc. (Aqua NC) currently owns and operates an existing well
water system serving Bannertown Hills Subdivision (Bannertown), located east of
Mt. Airy, N.C. in Surry County. Well #2 of the water system uses an assembly of
green sand filters in the treatment of groundwater prior to distribution to the
Bannertown Hills community. These filters are backwashed, using potable water,
approximately once every two days. This backwash is a relatively small volume of
approximately 1,600 gallons. The discharge leaves the well house via a 1" PVC
pipe and is released into an intermittent stream that is an unnamed tributary to
Faulkner 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 Bannertown Hills water system currently has 28 customers. Well # 2 is
approved for 12 gpm. No expansion of this well is planned and the system is
wit sufficient to serve the subdivision. Whereas the subdivision is fully developed and
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
1'' use or backwash discharge flow.
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
from Well # 2 at Bannertown Hills 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 the Bannertown Hills 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. 29 min. 41 sec. W
Latitude: 36 deg. 33 min. 42 sec. N

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 1.8 miles away.
The general area has soil characteristics which are limited to the possibility of on
site 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
Faulkner Creek, which is 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. Faulkner Creek is listed on the North Carolina
303(d) list as having impaired biological integrity.
Section 3: Existing Utilities
3.01 Public Facilities:
The nearest existing public sewer is located approximately 1.8 miles northwest of
the existing well near the junction of Westfield Road and Meadow Street. The
distance that would be required for sewer force mains to be installed would be
approximately 9,500 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 City of Mt. Airy, Public Works Department provides sewer services in this
area. Mr. Mitch Williams, P.E., City Engineer, was consulted and has advised that
there are no established plans for extension of sewer service any closer to
Bannertown Hills 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 Bannertown Hills 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 and a half -mile radius.

Section 4: Alternatives For Service
"' 4.01: On site surface and/or subsurface disposal:
Subsurface Disposal:
WV
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 Woolwine Fairview -Westfield soils with characteristics that are
somewhat limited to 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, RS, Surry County
Environmental Health Director concerning the possibilities of subsurface disposal.
irl 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
p, 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.
MA 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.
Psi
Aqua North Carolina only owns a 100 foot radius around the well. Whereas the
well must have a 100 foot buffer to any disposal site, this would necessitate that
,v9 Aqua North Carolina acquire additional property to allow for the possible
subsurface disposal site, repair/reserve area and buffers.
Rim 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
fm 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:
Disposal 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.

6
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
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.
4.04: 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
to 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
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 823 %
greater. This represents a difference of $ 4,085 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
the 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
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.
Therefore, based on the design flow, the area required for subsurface disposal is:
1,600 gpd / 0.25 gpd/sq. ft. = 6,400 SF
Whereas it is required to maintain an equal size area as a reserve for future repair, the
required area is 12,800 SF. Appendix D contains a map, which delineates the area that
might be available for subsurface disposal.
Assuming a roughly rectangular field (128 ft x 100 ft. for the initial drain field plus repair
and In order to maintain the required buffer to property lines), the minimum estimated
land required is 17,760 SF or .41 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 1,600 gpd, this results in an estimated disposal area of 8,000 SF. Allowing
a recommended 50% repair area, the required total area is 12,000 SF. Assuming a
roughly rectangular field (110 ft x 110 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

investigation. The numbers in the value columns range from 0.01 to 1.00. The larger the value, the greater the
potential limitation. The table shows only the top five limitations for any given soil. The soil may have additional
limitations]

Residuals Management Plan
Prepared by: J. Thurman Horne, P.E.
Horizon Engineering & Consulting, Inc.
1
24
Residuals Management Plan:
The proposed continued surface water discharge will have no impact on existing residuals management.
There 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.
