BACKGROUND:
Windgate Subdivision — Well #1 is a Class II, greensand water treatment plant that provides potable
water for 60 customers in the residential subdivision. There are currently 4 greensand filters, the filters
are backwashed approximately once every day. The backwash rate for 4 filters is 1,680 gallons. Well #1
is approved for 85 gpm, which is sufficient to serve the subdivision. The subdivision is fully developed
and there is no potential for increased flow.
Effluent limitations are implemented based on the new Guidance for Greensand Water Treatment Plants.
The Division has determined that the existing Water Treatment Plant is necessary to accommodate social
and economic growth in the area and that it will not result in contravention of surface water quality
standards or loss of designated uses in the receiving stream.

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 Windgate Subdivision, located outside Dobson off
Simmons Road. I 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 Windgate community. The filters are "backwashed" with water
approximately once every day and approximately 1,680 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

Section 'I: General
1.01 Introduction:
Aqua North Carolina, Inc. (Aqua NC) currently owns and operates an existing well
water system serving Windgate Subdivision (Windgate), located northeast of
Dobson, N.C. in Surry County. Well #1 of the water system uses an assembly of
green sand filters in the treatment of groundwater prior to distribution to the
Windgate community. These filters are backwashed, using potable water,
approximately once every day. This backwash is a relatively small volume of
approximately 1,680 gallons. The discharge exits the well house via a 2" PVC pipe
and is released into an intermittent stream that is an unnamed tributary to Fisher
River in the Yadkin River basin.
Fon
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
im existing backwash discharge.

The Windgate water system currently has 60 customers. Well # 1 is approved for
85 gpm. No expansion of this well is planned and the current two well system is
sufficient to serve the subdivision. Whereas there are no plans for expansion of
the subdivision or service area, there is no potential for any substantial population
increase to affect the existing rate of water use or backwash discharge flow (1,680
gpd.)
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 # 1 at Windgate 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 Windgate 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. 40 min. 43 sec. W
Latitude: 36 deg. 24 min. 29 sec. N

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 2.7 miles away.
The general area has soil characteristics which are limited to the possibility of on
. site treatment and disposal.
MI
PM
P,
NM
PEII
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 Fisher
River 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
waters.
Section 3: Existing Utilities
3.01 Public Facilities:
The nearest existing public sewer is located approximately 2.7 miles southwest of
the existing well at the junction of North Main Street and Ridge Road. The distance
that would be required for sewer force mains to be installed would be
approximately 14,000 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. This
sewer is operated by the Town of Dobson.
The Town Manager's office was consulted and has advised that this is the nearest
location of available sewer and that the Town has no plans within the next ten
years or beyond to extend service any closer to the Windgate vicinity.
MEI
3.02 Private Facilities:
There are no known existing private sewer utilities within any reasonable proximity
ar
of Windgate that would be available for consideration as a possible alternative. A
review of available information did not reveal that there are any potentially useable
M, private sewer facilities within a two mile radius.

Section 4: Alternatives For Service
FM
4.01: On site surface and/or subsurface disposal:
no Subsurface Disposal:
PMIt
mat
PIM
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
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. 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 100 foot radius 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.
Given the limitations described in the attached soil survey, 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:
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 soils surveys for this area has 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
P., 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
wi purposes of this assessment, a storage requirement of 60 days will be assumed.
PR
MR
Whereas all of the area currently owned by Aqua NC is within the required 100
foot buffer zone, the only possible alternative for on site disposal, either by
subsurface or surface application, would require the acquisition of off site
properties for disposal.
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.

NOR
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 capital 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 1,023 %
greater. This represents a difference of $2,139 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 alternative is the continued discharge
of the relatively benign filter backwash waters.
Section 6: Proposed Wastewater Treatment Facilities:
an, 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
fir 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:
1,680 gpd / 0.25 gpd/sq. ft. = 6,720 SF
Whereas it is required to maintain an equal size area as a reserve for future repair, the
required area is 13,440 SF. Assuming a roughly rectangular field (135 ft x 100 ft. for the
initial drain field plus repair and In order to maintain the required buffers to property lines,

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 1,680 gpd, this results in an estimated disposal area of 8,400 SF. Allowing
a recommended 50% repair area, the required total area is 12,600 SF. Assuming a
roughly rectangular field (110 ft x 115 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 172,225 SF or approximately 4 acres.

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 class 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
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 white 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.
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. to these soils, seepage of the effluent can result in
wir 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.
ran 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.
raln Information in this table is intended for land use planning, for evacuating 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.
MIR
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.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
J The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
QM-02 The RPD and/or percent recovery for this QC spike sample cannot be accurately calculated due
to the high concentration of analyte inherent in the sample.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.
