can be made. Such notification to the regional supervisor shall be made during the nonnal office
hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday, excluding State Holidays.
3. Please note that the Division has concerns regarding the amount of runoff calculated in the water
balance for the irrigation system. If at any time runoff, ponding or other excessive irrigation
problems occur, the Permittee may be required to acquire more irrigation area or increase the
storage within the system. In addition, future phases of this project shall be required to justify
similar runoff calculations.
4. The Permittee shall use a synthetic liner of sufficient thickness if native soils on -site are not
available to meet the hydraulic conductivity of no greater than 1 x 10-6 centimeters per second for
a compacted 1-foot clay liner.
The reclaimed water utilization facilities shall be effectively maintained and operated at all times
so that there is no discharge to the surface waters, nor any contamination of ground waters, which
will render them unsatisfactory for normal use. In the event that the facilities fail to perform
satisfactorily, including the creation of nuisance conditions or failure of the irrigation area to
adequately assimilate the wastewater, the Permittee shall take immediate corrective actions
including those actions that may be required by the Division of Water Quality (Division), such as
the construction of additional or replacement wastewater treatment and disposal facilities.
6. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to
surface water or ground water resulting from the operation of this facility.
7. The residuals generated from these treatment facilities must be disposed in accordance with
General Statute 143-215.1 and in a manner approved by the Division.
8. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
9. The following buffers shall be maintained:
a. 100 feet between wetted areas and water supply wells,
b. 100 feet between wetted areas and waters classified as SA,
c. 25 feet between wetted areas and surface waters not classified as SA,
d. 100 feet between wastewater treatment units and wells,
e. 50 feet between reclaimed water storage/irrigation ponds and property lines, and
f. 50 feet between wastewater treatment units and property lines.
10. Public access to the irrigation sites shall be controlled during active site use. Such controls may
include the posting of signs showing the activities being conducted at each site. A sign shall be
posted in plain sight in the clubhouse showing these activities.
7.

11. The disposal system shall be connected to a rain or moisture sensor that shall indicate when
wastewater application is not appropriate in accordance with Condition 1I(4) of this permit, or
irrigation shall only occur upon manual operation by the Operator in Responsible Charge.
12. The following shall be requirements for the reclaimed water distribution, storage, and utilization
facilities:
a. All reclaimed water valves, storage facilities, and outlets shall be tagged or labeled to warn
the public or employees that the water is not intended for drinking. Where appropriate, such
warning shall inform the public or employees to avoid contact with the water.
b. All reclaimed water piping, valves, outlets, and other appurtenances shall be color -coded,
taped, or otherwise marked to identify the source of the water as being reclaimed water.
L All reclaimed water piping and appurtenances shall be either colored purple (i.e., Pantone
522) and embossed or integrally stamped or marked "CAUTION: RECLAIMED
WATER — DO NOT DRINK" or be installed with a purple (i.e., Pantone 522)
identification tape or polyethylene vinyl wrap. The warning shall be stamped on opposite
sides of the pipe and repeated every three feet or less.
ii. Identification tape shall be at least three inches wide and have white or black lettering on
purple (i.e., Pantone 522) field stating "CAUTION: RECLAIMED WATER — DO NOT
DRINK." Identification tape shall be installed on top of reclaimed water pipelines,

d. Above -ground hose bibs (i.e., spigots or other hand -operated connections) shall not be
present. Hose bibs shall be located in locked below -grade vaults that shall be clearly labeled
as being of non -potable quality. As an alternative to the use of Iocked below -grade vaults
with standard hose bibs services, hose bibs, which can only be operated by a special tool or
connected to a special hose connection, may be placed in non -lockable underground services
boxes clearly labeled as non -potable water.
13. The soils located on site contain high amounts of silt and clay and are susceptible to compaction
when wet. The Permittee shall ensure all necessary precautions are taken to avoid compaction
that will have an adverse effect upon the drainage of the irrigation areas.
14. Areas of this site contain soils that are underlain by weathered and hard bedrock at shallow
depths. The Permittee shall ensure that extreme care is taken during grading so that a minimum of
12 inches of soil remains above any bedrock when construction is complete. Areas trapped as
Misenheimer and Goldston are the areas most likely to contain soils where the depth to bedrock is
less than 12 inches.
15. Areas of this site contain soils that have a seasonal high water table that is within 1 foot of the soil
surface. The Permittee shall carefully monitor water tables in these areas to ensure that
wastewater will not be applied when the vertical separation between the wastewater and the
seasonal high water table is less than one (1) foot.

16. Updn the completed installation of all 5 piezometers listed within the water table monitoring plan,
the applicant shall submit to the Aquifer Protection Section, Raleigh Regional Office, 3800
Barrett Drive, Raleigh, NC 27609, complete soil descriptions, piezometer construction details,
and longitude/latitude for each of the piezometers. The requested information must be received
and acknowledged in writing by the Aquifer Protection Section, prior to the commencement of
spray irrigation of reclaimed water on any of the Primary Low Spray Areas. All piezometers shall
be afforded reasonable protection against damage during construction and use, as well as secured,
with a locking well cap, to reasonably ensure against unauthorized access and use, as per 15A
NCAC 02C .0108. All water table monitoring data shall be recorded and kept on file by the
Permittee for review by the Division of Water Quality.
17. Upon the completion of site grading and shaping, an updated soil scientist site evaluation report
shall be submitted to the Aquifer Protection Section, Raleigh Regional Office, 3800 Barrett
Drive, Raleigh, NC 27609, for all spray field areas where the soil has been significantly altered
by grading, cutting or filling. This report shall include the driving range from the original permit,
which was still under construction during the review process. This report shall specifically
address, but not be limited to, soil features such as depth to seasonal high water table, depth to
fractured bedrock, saturated hydraulic conductivity of the least permeable layer, and soil
compaction, as well as any other properties that might impact the soil's ability to accept irrigation
water. The report should also certify that the significantly altered areas are still capable of
accepting the designed Ioading rate. The requested information must be received and
acknowledged in writing by the Aquifer Protection Section., prior to the commencement of spray
irrigation of reuse water on any of the amended areas.

maintained. This gauge shall have readily visible permanent markings indicating the maximum
liquid level at the top of the temporary liquid storage volume, minimum liquid level at the bottom
of the temporary liquid storage volume, and top of the dam elevations. Caution must be taken not
to damage the integrity of the liner when installing the gauge.
12. A protective vegetative cover shall be established and maintained on all earthen basin
embankments (outside toe of embankment to maximum pumping elevation), berms, pipe runs,
erosion control areas, and surface water diversions. Trees, shrubs, and other woody vegetation
shall not be allowed to grow on the earthen basin dikes or embankments. Earthen basin
embankment areas shall be kept mowed or otherwise controlled and accessible.
13. All wastewater shall be routed to the five-day holding pond should the limit for fecal coliforrn
(daily maximum concentration of 25 per 100 ml) or turbidity (instantaneous maximum of 10
NTU) be exceeded, until such time that the problems associated with the treatment capability of
the wastewater treatment plant have been corrected. The wastewater in the five-day holding pond
shall be pumped back to the treatment plant for re -treatment or treated in the five-day pond prior
to discharge to the storage pond.
III. MONITORING AND REPORTING REQUIREMENTS
1. Any monitoring (including groundwater, surface water, soil or plant tissue analyses) deemed
necessary by the Division to insure surface and ground water protection will be established and
an acceptable sampling reporting schedule shall be followed.
2. Influent flow shall be continuously monitored and daily flow values shall be reported on Form
NDMR. Influent flow may be represented by effluent flow from the wastewater treatment system
prior to storage.
The Permittee shall install an appropriate flow measurement device consistent with approved
engineering and scientific practices to ensure the accuracy and reliability of influent flow
measurement. Flow measurement devices selected shall be capable of measuring flows with a
maximum deviation of less than 10 percent from true flow, accurately calibrated at a minimum of
once per year, and maintained to ensure that the accuracy of the measurements is consistent with
the accepted capability of that type of device. The Permittee shall keep records of flow
measurement device calibration on file for a period of at least three years. At a minimum, data to
be included in this documentation shall be:
a. Date of flow measurement device calibration

may take place on the property. The map shall also be surveyed using the North American
Datum of 1983 coordinate system and shall indicate the datum on the map. All bearings or
azimuths shall be based on either the true or NAD 83 grid meridian. If a Global Positioning
System (GPS) is used to detennine the latitude and longitude of the horizontal control monument,
a GPS receiver that has the capability to perform differential GPS shall be used and all data
collected by the GPS receiver will be differentially corrected.
The maps and any supporting documentation shall be sent to the N.C. Division of Water Quality,
Aquifer Protection Section, Land Application Unit, 1636 Mail Service Center, Raleigh, N.C.
27699-1636.
Upon completion of all well construction activities, a certification must be received from a
professional engineer certifying that the monitoring wells are located and constructed in
accordance with the Well Construction Standards (15A NCAC 2C) and this permit. This
certification should be submitted with copies of the Well Completion Form (GW-1) for each well.
Mail this certification and the associated GW-1 forms to the Aquifer Protection Section, Land
Application Unit, 1636 Mail Service Center, Raleigh, N.C. 27699-1636.
For the initial sampling of the well as specified elsewhere in the permit, the permittee shall
submit a copy of the GW-1 Form (Well Completion Form) with the Compliance Monitoring
Form (GW-59) for that well. Compliance Monitoring Forms that do not include copies of the
GW-1 form will be returned to the permittee without being processed. Failure to submit these
forms as required by this permit may result in the initiation of enforcement activities pursuant to
NC General Statutes 143-215.6.
7. Monitor wells MW-1, MW-2 and MW-3 shall be sampled initially after construction (and prior to
waste disposal operations) and thereafter every March, June, September and December for the
following parameters:
Water Level
Chloride
Total Organic Carbon (TOC)
Nitrate (NO3 N)
Fecal Coliforms

pH
Total Dissolved Solids (TDS)
Total Phosphorus
in

8. The measurement of water levels must be made prior to sampling for the remaining parameters.
The depth to water in each well shall be measured from the surveyed point on the top of the
casing.
9. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the
relative elevation of the measuring point for each monitoring well.
10. If TOC concentrations greater than 10 mg/l are detected in any downgradient monitoring well,
additional sampling and analysis must be conducted to identify the individual constituents
comprising this TOC concentration. If the TOC concentration as measured in the background
monitor well exceeds 10 mg/l, this concentration will be taken, to represent the naturally occurring
TOC concentration. Any exceedances of this naturally occurring TOC concentration in the
downgradient wells shall be subject to the additional sampling and analysis as described above.
11. The results of the sampling and analysis must be received on Form GW-59 (Groundwater Quality
Monitoring: Compliance Report Form) by the Division of Water Quality, Information Processing
Unit, 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 on or before the last
