Re: Plan Approval Requirements
Bishop's Ridge Subdivision
PWSID# 02-34-197, Forsyth County
Dear Mr. Roberts:
On August 15, 2007, Ms. Rose Pruitt of the N.C. Division of Water Quality and I visited the above
referenced community water system. The purpose of this visit was to verify the removal of the
greensand filtration equipment in Well House #1.
Inorganic chemical samples were collected from Well #1 and the entry point to the distribution
system (E01) to be analyzed for iron, manganese, and pH. The results of the samples were in
compliance with the State Drinking Water Parameters (copies enclosed).
Our records indicate that plans and specifications for the water system serving Bishop's Ridge
Subdivision were approved under Division of Environmental Health serial number 93-02545,
datedAugust-26, 4992, (copy -enclosed):-- These -plans' -called- for -the--continuous application- of -
chlorine at both of the wells along with the addition of Aqua-Mag sequestering agent at Well #1.
Currently, the treatment equipment at Well 91 consists of the continuous application of chlorine.
The treatment equipment at Well #2 consists of the continuous application of chlorine and caustic
soda to the drinking water.
Therefore, this office is requiring that as -built plans and specifications for the treatment
equipment in both of the well houses be submitted by October 31, 2007. Please note that this rule
infraction was brought to Mr. Gary Moseley's attention in my letter of June 16, 2006 (copy
enclosed). An administrative penalty request will be forwarded to the Protection and
Enforcement Branch on November 1, 2007 if the revised plans and specifications are not
submitted to the Winston-Salem Regional Office. Another option would be to operate the water
system per the approved plans.

We need to expedite the filter vessel removal from Bishop's Ridge. In discussions with NC DWQ this
morning they would like to inspect the well house in just over two weeks to confirm that the vessels
have been removed and that there is no need for the NPDES permit. Can you coordinate a joint
inspection between the regional DWQ (Ms. Rose Pruitt) and PWSS during the week of August 6th?
Eddie,
Can you send a letter to the NC PWSS P&S Group asking to modify our approved plans for this

Well they said they don't need the green sand filtration any more so they will not
be backwashing any more. I guess DWQ will have to
make an announced inspection.

1. Plans shall include a project vicinity map.
2. Plans shall include wells layout site plans and Wells # 1 backwash discharge point and receiving
stream or creek. Project cannot be approved until NPDES permit have been obtained.
3. Filter backflow flow rate is generally twice or greater of service flow rate with approximately 15 to

Attached are four (4) copies of an application for permit signed by Aqua North Carolina, Inc.,
four (4) copies of the Engineering Alternatives Evaluation (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 Bishops Ridge
Subdivision, located outside the Rural Hall, N.C. town limits. The EAA contains a map which
indicates 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 Bishops Ridge community. The filters are "backwashed" with
water approximately once every three days and approximately 1,680 gallons of water is then
discharged into 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.
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.)

Chemical Analysis of Raw Water Supply
Section 1: General
1.01 Introduction:
Aqua North Carolina, Inc. (Aqua NC) currently owns and operates an existing well
water system serving Bishops Ridge Subdivision (Bishops Ridge), located
southeast of Rural Hall, N.C. in Forsyth County. Well,#1 of the water system uses
an assembly of green sand filters in the treatment of groundwater prior to
distribution to the Bishops Ridge community. These filters are backwashed, using
potable water, approximately once every three days. This backwash is a relatively
small volume of approximately 1,680 gallons. The discharge exits the well house
via a 1" PVC pipe and is released into an intermittent stream that is an unnamed
tributary to Rough Fork in the Roanoke 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 Bishops Ridge water system currently has 66 customers. Well # 1 is approved
for 29 gpm. No expansion of this well is planned and the current two well system
is sufficient to serve the subdivision. Whereas this well is limited by its current yield
capacity and since this capacity is being utilized, there is no potential for any
population increase to affect the existing rate of water 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
GreenVnd 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 Bishops Ridge 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 Bishops Ridge 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:-80.2628689 W
Latitude: 36.2310664 N
4
2.02 Site Characteristics:
The subdivision is located in a rural portion of Forsyth county, outside any
municipal limits and remote from public water and/or sewer. The nearest existing
sewer is approximately 1.6 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
Rough Fork 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 1.6 miles northwest of
the existing well at the junction of Academy Street and Simmons Road. The
distance that would be required for sewer force mains to be installed would be
approximately 8,000 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 Rural Hall.
The Town Manager of Rural Hall was consulted on February 9, 2007 and he has
advised that this is the nearest location of available sewers and that the Town has
no plans within the next five years or beyond to extend service any closer to the
Bishops Ridge vicinity.
3.02 Private Facilities:
There are no known existing private sewer utilities within any reasonable proximity
of Bishops Ridge that would be available for consideration as a possible
alternative.

Section 4: Alternatives For Service
4.01: On site surface and/or subsurface disposal:
Subsurface Disposal:
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 Hiwassee soils with characteristics that are somewhat limited to
very limiting with respect to the potential for subsurface disposal. Subsurface
disposal requires buffers and land for the drainfields as well as equal areas of
suitable soil, be available and maintained as a repair/replacement areas that are
simply not available for individual on site disposal.
The only practical possibility for subsurface disposal would be to construct a
subsurface disposal system on lands acquired beyond the 100 foot buffer required
to protect the well. This would necessitate that additional lands be acquired that
are not now owned by Aqua NC. Some attempts have been made to explore this
possibility but have been unsuccessful. An area of approximately 1/4 acre that
adjoins,the current welt lot was investigated but the property owners were not
interested in selling.
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.
fjThis 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.
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
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.
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.
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 1,621 %
greater. This represents a difference of $3,205 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:
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 0.10 gpd/sq. ft. is
acceptable.
Therefore, based on the design flow, the area required for subsurface disposal is:
1,680 gpd / 0.10 gpd/sq. ft.= 16,800 SF
Whereas it is required to maintain an equal size area as a reserve for future repair, the
required area is 33,600 SF. Assuming a roughly rectangular field (340 ft x 100 ft.for the
initial drain field plus repair and In order to maintain the required 50 foot buffer to property
lines), the minimum estimated land required is 88,000 SF or 2.0 acres.

313. 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 (415 ft x 415 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.

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 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 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.
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 Horne, P.E.
Horizon Engineering & Consulting, Inc.
Residuals Mannement 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.

NPDES Permit Application
Existing Well Backwash Discharge
Bishops Ridge Subdivision
Forsyth County
Dear Mr. Watts:

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 Bishops Ridge Subdivision, located outside the Rural
Hall, N.C. town limits. 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 Bishops Ridge community. The filters are "backwashed" with water
approximately once every three days and approximately 1,680 gallons of water is then discharged
into the nearby stream.
This has been in service for a number of years and we are not aware of any 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. Therefore,
we would certainly appreciate anything you can do to expedite review of this attachment and
return of the signed form. If you could sign and fax a copy of this back to me (fax: 704-788-
4455) on Monday or Tuesday, it would be very helpful and we would certainly appreciate it. I
would still like to receive a copy by mail as well if possible.
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.)
Sincerely,
Burman orne, P. E.
Attachment A. Local Government Review Form
General Statute Overview, North Carolina General Statute 143-215.1 (c)(6) allows input from local governments in the issuance
of NPDES Permits for non -municipal domestic wastewater treatment facilities. Specifically, the Environmental Management
Commission (EMC) may not act on an application for a new non -municipal domestic wastewater discharge facility until it has
received a written statement from each city and county government having jurisdiction over any part of the lands on which the
proposed facility and its appurtenances are to be located. The written statement shall document whether the city or county has a
zoning or subdivision ordinance in effect and (if such an ordinance is in effect) whether the proposed facility is consistent with the
ordinance. The EMC shall not approve a permit application for any facility which a city or county has determined to be
inconsistent with zoning or subdivision ordinances tuzless the approval of such application is determined to have statewide
significance and is in the best interest of the State.
Instructions to the Applicant: Prior to submitting an application for a NPDES Permit for a proposed facility, the applicant
shall request that both the nearby city and county government complete this form. The applicant must:
• Submit a copy of the permit application (with a written request for this form to be completed) to the clerk of the city and
the county by certified mail, return receipt requested.
■ If either (or both) local government(s) fail(s) to mail the completed form, as evidenced by the postmark on the certified
mail card(s), within 15 days after receiving and signing for the certified mail, the applicant may submit the application to
the NPDES Unit.
• As evidence to the Commission that tie local governments) failed to respond within 15 days, the applicant shall submit a
copy of the certified mail card along with a notarized letter stating that the local government(s) failed to respond within tie
15-day period.
Instructions to the Local Government: The nearby city and/or county government which may have or has jurisdiction over
any part of the land on which the proposed facility or its appurtenances are to be located is required to complete and return this
form to the applicant within 15 days of receipt. The form must be signed and notarized.
