Gaston County
FOR THE
continued operation of a 5,000 GPD spray irrigation treatment and disposal facility consisting of a 5,000
GPD extended aeration plant with a comminutor, bar screen, two aeration basins, clarifier, chlorine contact
chamber and a 0.235 MG storage lagoon, a 120 GPM irrigation pump and approximately 2.5 acres of
irrigation field to serve A. B. Carter, Inc., with no discharge of wastes to the surface waters, pursuant to
the modification request April 29, 1996, and in conformity with the project plan, specifications, and other
supporting data subsequently filed and approved by the Department of Environment, Health and Natural
Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until February 28, 2001, shall void Permit
No. WQ0004270 issued March 26, 1996, and shall be subject to the following specified conditions and
limitations:
I. PERFORMANCE STANDARDS
1. 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 Perrnittee shall take immediate
corrective actions including those actions that may be required by the Division of
Environmental Management, 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 groundwaters resulting from the operation of this facility.
3. 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 North Carolina'Division of
Environmental Management.
4. Diversion or bypassing of the untreated wastewater from the treatment facilities is
prohibited.

5 . 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.
II. OPERATION AND MAINTENANCE REQUIREMENTS
1. The facilities shall be properly maintained and operated at all times.
2. Upon classification of the facility by the Certification Commission, the Permittee shall

3. Monitor wells MW-19 and MW-20 shall be sampled initially after construction for the
following parameters:
Aluminum Ammonia Nitrogen Cadmium
Chloride Chromium Copper
Fecal Coliforms Iron Lead
Nickel NO3 pH
Silver SO4 TDS
TOC Water Levels Zinc
Volatile Organic Compounds - In November only (by Method 1 or 2 below)
Method 6230D (Capillary - Column), "Standard Methods For The Examination of
Water and Wastewater", 17th ed., 1989
and;
Monitor wells MW-19 and MW-20 shall be sampled every February and August after the
initial sample. Parameters which are not present in detectable quantities in the initial
sampling will not be required to be sampled in subsequent sampling.
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 relative elevation of the measuring point for each monitoring well.
If TOC concentrations greater than 10 mg/1 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.
If any volatile organic compounds are detected by Method 6230D, then the Mooresville
Regional Office Groundwater Supervisor, telephone number 704-663-1699, 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 results of the sampling and analysis shall be sent to the Groundwater Section, Permits
and Compliance Unit, P.O. Box 29578 Raleigh, N.C. 27626-0578 on Form GW-59
[Compliance Monitoring Report Form] every March and September.
4. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
5. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary
for the disposal system constructed prior to December 31, 1983 is established at either (1)
500 feet from the waste disposal area, 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 143-215.6A(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.

6 . 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.
7. The Mooresville Regional Office, telephone number 704-663-1699, shall be notified at
least forty-eight (48) hours prior to the construction of any monitoring well so that an
inspection can be made of the monitoring well location. Such notification to the regional
groundwater supervisor shall be made during the normal office hours from 8:00 a.m. until
5:00 p.m. on Monday through Friday, excluding state holidays.

e. the relative elevation of the top of the well casing (which shall be known as the
"measuring point"), and
f. the depth of water below the measuring point at the time the measuring point is
established.
The survey shall be conducted using approved practices outlined in North Carolina General
Statutes Chapter 89C and the North Carolina Administrative Code Title 21, Chapter 56.
The surveyor shall establish a horizontal control monument on the property of the waste
disposal system and determine the latitude and longitude of this horizontal control
monument to a horizontal positional accuracy of +/- 10 feet. All other features listed in a.
through e. above shall be surveyed relative to this horizontal control monument. The
positional accuracy of features listed in a. through e. above shall have a ratio of precision
not to exceed an error of closure of 1 foot per 10,000 feet of perimeter of the survey. Any
features located by the radial method will be located from a minimum of two points.
Horizontal control monument shall be installed in such a manner and made of such
materials that the monument will not be destroyed due to activities that 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 determine the latitude and longitude of the horizontal control monument, a
