Subject: Minor modification of NPDES Permit NCO088927
Meadow Ridge WTP
Guilford County
Dear Mr. Becker:
The Division received information from Ms. Laurie Ison of your company that the parameter code in
the subject permit was incorrect. Specifically, we determined that the parameter code for turbidity (00076)
was outdated and had since been replaced with a new code (00070). This modification corrects the error,
and is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the
Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated
October 15, 2007 (or as subsequently amended). Insert the attached page into your permit and discard the
old page.
This modified permit includes the following changes from your current permit:
➢ The parameter code for turbidity has been corrected.
If any parts, measurement frequencies or sampling requirements contained in this modification are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30)
days following receipt of this letter. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative Hearings
(6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such demand is made, this
decision shall be final and binding.
This permit is not transferable except after notice to the Division. The Division may require
modification or revocation and reissuance of the permit. This permit does not affect the legal requirements
to obtain other permits which may be required by any other Federal, State, or Local governmental
regulation. If you have any questions concerning this matter, please contact Charles H. Weaver at (919)
807-6391 or via e-mail [[e-mail]].

being physically located in an area where less than 10 percent of the households have broadband
access, then a temporary waiver from the NPDES electronic reporting requirements may be granted
and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3) or
alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
mailing address above. See "How to Request a Waiver from Electronic Reporting" section below.

temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data
and reports shall be submitted electronically to the Division unless the permittee re -applies for and is
granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting
waivers are not transferrable. Only permittees with an approved reporting waiver request may
submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.

1) If the backwash source water uses fluorinated water then total fluoride monitoring
should be added.
2) If the backwash source water has been treated with zinc based corrosion inhibitor then
zinc monitoring should be added.
Important SOC, JOC or Compliance Schedule dates: NA.
4. Alternative Analysis Evaluation: As per Thurman Horne, PE, no other disposal options are
available for this type of operation due to lack of available/suitable land and or economic
constraints. However, no formal evaluation has been conducted by local Environmental
Health Department for suitability of subsurface system. Site is approximately 2.44 acres
according to PE proposal. Well buffer of 100 feet would eliminate some of this land, but
there is still a potential for the remaining land to be used. PE states that "given the
limitations described in the attached soil survey and discussed above, it is doubtful that this is
a viable option". He also states that "...before a final design and/or approval could be given,
an actual on site soils evaluation would be required".
PART IV - EVALUATION AND RECOMMENDATIONS
WSRO recommends issuance of the permit for the discharge created from backwashing of
the green sand filters at Meadow Ridge Subdivision with the following stipulations:
1) If TRC limit is imposed, it Day be necessary to add dechlorination system prior to discharge.
According to Public Water Supply staff, drinking water must meet a minimum of 0.2 mg/L
TRC. If chlorinated water is used for backwash, the discharge will most likely not be able to
meet the 17 ug/L limit (or 50 ug/L compliance limit).
2) System must discharge into UT to Kings Creek, not onto ground.

BACKGROUND
The Meadow Ridge Subdivision dual well -feed potable water system was required to install
greensand filters to comply with regulatory drinking water standards. The system supplies
potable water to 65 customers and has no anticipation of expansion that will significantly
impact the water demand or exceed the capacity of the filters. The owner and operator of
the system is Aqua North Carolina, Inc.
The installed greensand filter system consists of 4 filters using permanganate addition to
facilitate the desired physical iron filtration/removal. The filter units are located in the well
house. Zinc is not part of any additives that are in backwash water used at this time.
Chlorinated water is used to backwash the filters on an intermittent bases and estimated to
generate 2,500 gpd of wastewater. A 2 inch pipe conveys the backwash wastewater to an
unnamed tributary that flows into a local pond that then feeds into Kings Creek. Kings
Creek is in the Roanoke River Basin.
As required an EAA was submitted prior to acceptance of a NPDES application. Upon review
and additional clarification the Division concurred with the EAA conclusion that the
proposed surface discharge was the best alternative.
Additional backwash data and raw well data was requested before the NPDES application
could be developed. A staff report from the Winston Salem Region supports the issuance of
this permit provided the wastewater discharge was piped to the unnamed tributary. The
staff report also observed that this discharge will most likely require dechlorination to meet
the water quality standard for maximum Total Residual Chlorine (TRC), 17 µg/I (50 µg/L). As
requested by the Permittee the compliance limit for TRC will be delayed 6 months from the
permit effective date to allow for the installation of dechlorination.
The unnamed tributary is considered a zero flow B class stream. The greensand filter
backwash is an acceptable wastewater for this stream. This segment of the stream is not
impaired. Since the greensand filter system is existing and confirmed by the regional office
the AtoC and Engineering Certificate for the existing installation is not required. Future
components such as dechlorination will require approval by C, G & L.

NEW DISCHARGE FOR MEADOW RIDGE SUBDIVISION, GUILFORD COUNTY— GREEN SAND FILTER
BACKWASH
History: The greensand filters were needed to comply with public water supply requirements. A
consultant, Thurman Horne, P.E. prepared the application and EAA. The backwash wastewater discharge
scheme is a direct pipe releasing to a UT, no other post treatment. In the application the consultant
stated he had referenced our "2004 Permitting Strategy for Greensand Filtration" and that this
discharge should be acceptable into a zero flow stream. As a followed up I provided the consultant and
the owner, Aqua, Inc. with (1) the applicable water quality standards they must meet and (2) requested
radiological data, if it was available. I checked with C, G&L about how they would handle this and was
told they would evaluate this discharge to meet water quality standards at the end -of -pipe.
The Regional Office visited the site to prepare a staff report and recommendations and discovered that
the filters are already installed. Have requested TSS, turbidity, and pH data on discharge.
Description: Two wells supply drinking water to 65 customers. Greensand filters will be backwashed
every other day with chlorinated water, 2,500 gpd.

Mr. Berry,
Thurman and I have discussed this and other comments received on this project, and will be working to provide the
additional information and data requested.
For the radiological sampling at the site, attached you will find sample results taken this quarter for Radium 226 & 228
(combined radium), which were placed on a three year sampling schedule based on distribution sampling. The other twc
contaminants (gross alpha and uranium) are on a nine year sampling schedule. These entry point sampling schedules (3
year and 9 year) were determined from distribution sample results taken, when the drinking water regulations required
sampling in the distribution. The nine year sampling period is based on non -detect sampling in the distribution. I hope
my explanation and results satisfies your requirement, I will be glad to talk with you on the specifics of the rule change
and our sampling frequency. I am fortunate to have once been the rule manager for these and other contaminants
when I worked for the Public Water supply section.

Subject: Review of Meadow Ridge Subdivision NPDES Application
Mr. Smart,
Based on the last information we received this NPDES application is for an existing greensand filter discharge and not
for a future installation. If this discharge is occurring then as part of the data to evaluate this operation we are
requesting analysis of three backwash discharge events. The analysis should include (1) Total Suspended Solids (TSS), (2)
pH, and (3) Turbidity. If no discharge is occurring then we will proceed with your application but please be aware the
NPDES permit will have limits at the end -of- pipe discharge at a minimum for TSS, pH, and TRC. Apparently no
wastewater treatment is planned.
I asked Mr. Horne previously about confirming if there were any existing radiological analysis associated with the
drinking water data that the county and/or public health may have required. Please advise.
If you have any questions let me know.

3.2.1.1 IESWTR and MES Turbidity Requirements
As part of the IESWTR promul a d in 1998, turbidity can be measured in two ways;
combined filter effluent (CF and dividual filter effluent (IFE). As of January 1,
2002, where population se ed is eq 1 or greater than 10,000 people, the CFE value
recorded at least every 4 ours must n t exceed 0.3 NTU in at least 95 percent of the
measurements taken e h month. The TIESWTR subsequently applied this limit to
smaller surface wate systems. Addition ly, the CFE level of representative samples
must not exceed 1 NTU at any time. Th ost significant change in the monitoring
requirements is at the utility is required t record the IFE every 15 minutes. In
addition to th past reporting and record ke ing requirements, the utility is required
to report to idity measurements within 10 d s after the end of each month.
Informa ' n in this report must include the foll wing:
■ TWe total number of CFE measurements taken donne the month.
The number and percentage of CFE measurements ken during the month, which
are less than or equal to the 95 percent limit. j
■ The date and value of any CFE measurements taken' uring the month, which
exceed 1.0 NTU for systems using conventional filtrate n treatment or direct
filtration, or which exceed the maximum level set by the state.
■ The IFE monitoring conducted and any follow-up actions taken for exceedances
during the month.
Utilities must maintain their record keeping for the above requirements for a
minimum of three years. The additional IFE follow-up and reporting requirements

two groups of chlorinated D s - tal trihalomethanes (TTHMs) and five haloacetic
acids (HAA5) - are regula d in two ages. In Stage 1, the EPA set MCLs of 80 µg/L
and 60 µg/L, as annual erages, for Ms and HAA5, respectively. Compliance is
nual a defined on the basis o a running anrage (RAA) of quarterly averages of all
samples. Monitor' requirements for system serving 10,000 people or more include
collection of four ater samples from the distrib tion system per quarter, per
treatment pl . The sampling locations should be resentative of the average
residence t' e in the distribution system with at least percent of the samples to be
taken at cations that represent the maximum residence ' e of water. For systems
monit ' g quarterly, if the RAA of quarterly averages cover any consecutive four-
quaier period exceeds the MCL, the system is in violation of the CL and must
ndtify the public, in addition to reporting to the State.
In addition, MRDLs in the distribution system were established for chlorine (4 mg/L),
chloramines (4 mg/L), and chlorine dioxide (0.8 mg/L). Table 6 provides the final
MRDLGs and MRDLs. Table 7 includes the MCLs and MCLGs for the disinfection

Section 1: General
1.01 Introduction:
Aqua North Carolina, Inc. (Aqua NC) currently owns and operates an existing well
water system serving Meadow Ridge Subdivision (Meadow Ridge), located
southwest of Stokesdale, N.C. in Guilford County. The well system is supplied by
the combined yield from two (2) wells that are equipped with an assembly of green
sand filters for the treatment of groundwater prior to distribution to the Meadow
Ridge community. These filters will be backwashed, using potable water,
approximately once every day. This backwash is a relatively small volume of
approximately 2,500 gallons. The discharge will leave the well house via a 2"
plastic pipe, and will be released into an intermittent stream that is an unnamed
tributary to Kings Creek in the Roanoke River basin.
The well system is existing but required that filters be installed in order to insure
consistent compliance with public water supply requirements. Whereas there will
be a discharge of low volumes of filter backwash, Aqua NC is required to obtain an
NPDES permit for the operation of the filters and backwash discharge.
The Meadow Ridge water system currently has 65 customers and has reached the
approved number of connections. The two (2) wells provide 105 gpm. No
expansion of the capacity of this well system is planned and the system is
sufficient to serve the subdivision. No expansion of the subdivision or service area
is planned. Therefore, there is no potential for any substantial population increase
to affect the existing rate of water use or proposed backwash discharge flow (2500
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" and "NPDES
Permitting Strategies For Potable Water Treatment Plants — September 2007".
1.02 Scope:
The scope of this project is limited to the investigation and evaluation of
alternatives for treating and/or disposing of the green sand filter backwash from
the well system at Meadow Ridge Subdivision. This includes consideration of the
feasibility of discharging the backwash to surface waters and options for
eliminating the existing discharge.
Section 2: Background Information
2.01 Project Area:

The existing service area is limited to Meadow 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 proposed discharge coordinates are: Longitude: -80 deg. 00 min. 16 sec. W
Latitude: 36 deg. 12 min. 40 sec. N
2.02 Site Characteristics:
The subdivision is located in an urban/rural portion of Guilford county, outside any
municipal limits and remote from public water and/or sewer. The nearest existing
sewer is approximately 7.25 miles (38,300 feet) away.
The general area has soil characteristics which are somewhat 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 Kings
Creek , which is class B waters. The receiving stream appears to be 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 proposed 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 7.25 miles southeast of
the existing well near the junction of NC Hwy 68 and Pleasant Ridge Road. The
distance that would be required for sewer force mains to be installed would be
approximately 38,300 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 Greensboro provides sewer services at this nearest location. The
possibility of sewer service being extended in this vicinity was discussed with Ms.
Beth Aheron, Guilford County, Environmental Services Coordinator. Ms. Aheron
has advised that there are no plans for any sewer extensions in the Meadow
Ridge vicinity. Therefore, consideration of connection to public sewers must be
made on the basis of considering the costs and requirements for extending a force
main and/or gravity sewers to reach the nearest available publicly owned sewers.

3.02 Private Facilities:
There are no known existing private sewer utilities within any reasonable proximity
of Meadow Ridge 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 over a three mile radius.
Section 4: Alternatives for Service
4.01: On site surface and/or subsurface disposal:
Subsurface Disposal:
Appendix F 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 Nathalie-Clifford-Hatboro soils with characteristics that are
somewhat limited to very limited with respect to the potential for subsurface
disposal. For the purposes of evaluating subsurface disposal as a potential
alternative, an application rate of 0.30 gpd/SF will be used as a reasonable
assumption for a possible loading rate for these type soils. Of course, before a
final design and/or approval could be given, an actual on site soils evaluation
would be required.
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 owns a 2.44 acre lot around the well. Whereas the wells 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 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 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.
The soil surveys for this area have determined this to have very limited potential
for on site surface 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 proposed 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 surface water 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 within a
reasonable proximity, 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 proposed 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 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 1,110 %
greater.
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 proposed discharge of the relatively benign filter backwash waters to surface
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 discharge to surface waters.

1. Surface Water Discharge at 2,500 GPD Flow Rate:
Considering that no additional treatment is expected as a consequence of any
forthcoming permit, there are no estimated additional capital costs.

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 somewhat 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 0.30 gpd/sq. ft. is acceptable.
Therefore, based on the design flow, the area required for subsurface disposal is:
2,500 gpd / 0.30 gpd/sq. ft.= 8,333 SF
Whereas it is required to maintain an equal size area as a reserve for future repair, the
required area is 16,667 SF. Appendix D contains a map, which delineates the area that
might be available for subsurface disposal.
In order to provide the required buffers to existing property lines, wells, drainageways,
etc., it is assumed that the required area will need to be increased by approximately 30%.
Therefore, it is estimated that the total land required to be obtained for subsurface
disposal is 21,667 SF or approximately 0.5 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 2,500 gpd, this results in an estimated disposal area of 12,500 SF.
Allowing a recommended 50% repair area, the required total area is 18,750 SF.
Assuming a roughly rectangular field (400 ft x 500 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 200,000 SF or approximately 4.7 acres.

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