continued operation of 2,540 linear feet of 8-inch gravity sewer;
continued operation of a 7,200 GPD spray irrigation treatment and disposal facility consisting of a 25-GPM influr `
pump station with dual pumps and high water alarms, approximately 1,130 linear feet of 2-inch force main, th.
facultative lagoon cells in series, a 2,500 gallon chlorine contact tank with a Iiquid chlorine feed system, and a 3.2 acre
spray irrigation disposal area;
to serve Satterwythe Place Subdivision with no discharge of wastes to the surface waters, pursuant to the application
received June 22, 1999, and in conformity with the project plan, specifications, and other supporting data subsequently
filed and approved by the Department of Environment and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until August 31, 2004, shall void Permit Numbers
WQ0005438 issued February 14, 1997 and 14536 issued April 23, 1987, and shall be subject to the following specified
conditions and limitations:
I. PERFORMANCE STANDARDS
L The spray irrigation 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.
2. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface or
Cr
groundwaters resulting from the operation of this facility.
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.

4. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited.
The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or places of public assembly under separate
ownership,
b) 150 feet between wetted area and property lines,
c) 100 feet between wetted area and wells,
d) 100 feet between wetted area and drainageways or surface water bodies,
e) 50 feet between wetted area and public right of ways,
f) 100 feet between wastewater treatment units and wells, and
g) 50 feet between wastewater treatment units and property lines.
Some of the buffers specified above may not have been included in previous permits for this waste
treatment and disposal system. These buffers are not intended to prohibit or prevent modifications, which
are required by the Division, to improve performance of the existing treatment facility. These buffers do,
however, apply to modifications of the treatment and disposal facilities which are for the purpose of
increasing the flow that is tributary to the facility. These buffers do apply to any expansion or
modification of the spray irrigation areas and apply in instances in which the sale of property would cause
any of the buffers now complied with, for the treatment and disposal facilities, to be violated. The
applicant is advised that any modifications to the existing facilities will require a permit modification.

IV. GROUNDWATER RE UIREMENTS
Monitor wells MW-5, MW-6, MW-7 and MW-8 shall be sampled every April, August, and December for
the following parameters:
Water Level pH
Chloride Total Dissolved Solids (TDS)
Fecal Coliforms Total Organic Carbon (TOC)
Nitrate (NO3) Ammonia Nitrogen
Volatile Organic Compounds - In December only by using Method 6230D below:
Method 6230D (Capillary — Column), "Standard Methods For The Examination of Water and
Wastewater", 17`E' ed., 1989
If any volatile organic compounds are detected by Method 6230D, then the Mooresville Regional Office
Groundwater Supervisor, telephone number [phone], must be contacted immediately for further
instructions regarding any additional follow-up analyses required. The results of all initial and follow-up
analyses must be submitted simultaneously.

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.
The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relati,,.
elevation of the measuring point for each monitoring well. The top of well casing elevations should be
accurate to within 0.01 feet.
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. .
The results of the sampling and analysis must be received on Fortin GW-59 (Groundwater Quality
Monitoring: Compliance Report Form) by the Groundwater Section, Permits and Compliance Unit, P.O.
Box 29578 Raleigh, N.C. 27626-0578 on or before the last working day of the month following the
sampling month.

or (2) at the property boundary, whichever is closest to the waste disposal area. An exceedance of
Groundwater Quality Standards at or beyond the Compliance Boundary is subject to immediate
remediation action in addition to the penalty provisions applicable under General Statute 14'
215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the disposal systems
midway between the Compliance Boundary and the perimeter of the waste disposal area. Any exceedance
of standards at the Review Boundary shall require remediation action on the part of the permittee.
All wells that are constructed for purposes of groundwater monitoring shall be constructed in accordance
with 15A NCAC 2C .0108 (Standards of Construction for Wells Other than Water Supply) and any other
state and local laws and regulations pertaining to well construction.
9. No land application of waste activities shall be undertaken when the seasonal high water table is less than
