Dear Mr. Gordon:
In accordance with your application received January 29, 1997, we are forwarding herewith Permit
No. WQ0011443, dated June 23, 1997, to The Community Bank for the continued operation of the
subject groundwater remediation facility.
In accordance with your modification requests, the Groundwater Section did not agree with the
substitution of MW-11 for MW-9 because MW-9 was required to track the existing plume on neighboring
property, not the effectiveness of the infiltration gallery. However, MW-11 can be sampled according to
the corrective action plan. Since MW-11 is not allowed to replace MW-9, the sampling schedule proposed
for MWA I also can not be approved.
The request to add recovery wells (former monitoring wells MW-9, MW-12, MW-13),-and
existing monitoring well MW-14 to the semi-annual sampling event associated with the Corrective Action
Plan (CAP) as they relate to operation of the remedial action system and capture of the plume, but not to
permit compliance, has been approved. However, the requirement to sample these wells does not need to
be included in the amended permit since they are not for compliance purposes.
This permit shall be effective from the date of issuance until January 31, 2001, shall void Permit
No. WQ0011443, issued May 31, 1996, and shall be subject to the conditions and limitations as specified
therein. Please pay particular attention to the monitoring requirements in this permit. Failure to establish
an adequate system for collecting and maintaining the required operational information will result in future
compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following receipt of
this permit. 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, P.O. Drawer
27447, Raleigh, NC 27611-7447. Unless such demands are made this permit shall be final and binding.

IV. GROUNDWATER REQUIREMENTS
The influent (composite from the supply manifold) and effluent from the treatment system
shall be sampled quarterly for the parameters specified below:
Benzene
Ethylbenzene
MTBE
Toluene
pH
Water Level
Xylenes
Napthalene
EDB
Lead
IPE
The analyses for the hydrocarbon compounds are to be performed by Standard Method
6210D. The samples shall be prepared and analyzed for lead by Standard Method 3030C.
Additionally, during the initial baseline analysis and the final site closure analysis, duplicate
samples to confirm the concentration of EDB in the wells shall also be analyzed by EPA

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.
3. The results of the sampling and analysis (influent/effluent and groundwater) must be
received on form 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.
4. The permittee shall retain copies of records of all monitoring information, including all
calibration and maintenance records, all original strip chart recordings for continuous
monitoring instrumentation and copies of all reports required by this permit, for a period of
at least 3 years from the date of the sample, measurement, report or application. Records
of this monitoring information shall include, but not be limited to, the following:
a, the date, exact place, and time of sampling or measurements,
b. the individual who performed the sampling or measurements,
c. the date the analyses were performed,
d. the analytical techniques or methods used, and
e. the results of any such sampling, measurements, and analyses.

5. The permittee shall report any monitoring or other information which indicates that any
contaminant may cause an endangerment to an underground source of drinking water and
any noncompliance with a permit condition of malfunction of the injection system which
may cause fluid migration outside the injection zone or area. The information shall be
provided to the Winston-Salem Regional Office orally within 8 hours of the occurrence and
as a written submission within five days of the occurrence. The written submission shall
contain a description of the noncompliance and its cause, the period of noncompliance,
including exact dates and times, and if the noncompliance has not been corrected, the
anticipated time it is expected to continue, and any steps taken or planned to reduce,
eliminate and prevent reoccurrence of the noncompliance.
6. Isoconcentration (lines connecting points of equal concentration) maps in both the vertical
and horizontal directions shall be developed using the groundwater monitoring data
collected prior to system operations for each constituent detected. Isoconcentration maps in
both the horizontal and vertical shall be developed using the groundwater monitoring data
for the months of March, June, September and December. A water level contour map must
also be developed on a quarterly basis. These maps shall be submitted along with all other
monitoring data for that period on a quarterly basis for the duration of the permit.
7. All components of the groundwater recovery, treatment, and disposal system shall be
properly- weather -proofed to prevent freezing and failure of the system.
8. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
9. The permittee shall submit, before December 31 of each calendar year, an annual report to
the regional groundwater supervisor at the Winston-Salem Regional Office, outlining the
injection volumes and the water levels measured within the infiltration gallery observation
well.
10. The water levels in the wells P1 and MW-2, in conjunction with well MW-10, shall be
monitored upon startup as often as required until steady state operation can be observed and
maintained, at a minimum, monthly thereafter along with the water levels in all other non -
pumping wells to indicate any trend line or tendency toward mounding and induced radial
gradients away from the gallery.
As a fail-safe against flooding of the gallery, a preset float actuated high level shutoff is to
be installed in P-1 and incorporated into the system design controls. The float sensor shall
be set at approximately 1 foot above the steady state water level in the gallery, not to exceed
an elevation 3 feet below the ground surface at the gallery location. Should shutdown
events in the gallery occur, or MW-2, and/or MW-10 water level measurements indicate a
tendency toward excessive mounding, the system pump rate shall be adjusted by
individually modifying the pump rate of each of the recovery wells to preclude offsite radial
flow contaminants and maintain capture of the plume.
11. A 4-inch diameter water -level monitoring observation well shall be constructed as part of
the infiltration gallery, as per the construction methods and specifications set forth in the
subject permit application. The well will be labeled P-1 and will comply with the
regulations set forth in 15A NCAC 2C .0108 (Standards of Construction of Wells Other
than Water Supply) and any other State and local laws and regulations pertaining to well
construction.
12. The regional groundwater supervisor at the Winston-Salem Regional Office, telephone
number [phone], shall be notified at least forty-eight (48) hours prior to the
construction of the P-i monitoring well so that an inspection can be made of the monitoring
well location. Such notification 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.

13. The groundwater recovery, treatment and disposal system shall be inspected weekly for the
duration of the permit. If it is determined that the system is malfunctioning, all repairs
should be made as soon as possible and reported to the regional groundwater supervisor at
the Winston-Salem Regional Office within 48 hours of the determination.
14. The groundwater treatment system shall consistently achieve Class GA Groundwater
Standards in the treated effluent, as outlined under Title 15A, Subchapter 2L, Section
.0202(g), prior to discharge in the infiltration gallery. The treated water discharged into the
infiltration gallery must not violate the Class GA Groundwater Quality Standards for any
constituent beyond the Compliance Boundary, nor cause the migration of contamination in
unaffected areas. If the treatment system fails to consistently achieve this standard,
additional treatment units or changes in operational methods, may be required.
V . INSPECTIONS
1. Adequate inspection, maintenance and cleaning shall be provided by the Permittee to insure
proper operation of the subject facilities.
2. The Permittee or his designee shall inspect the groundwater recovery and treatment
facilities to prevent malfunctions and deterioration, operator errors and discharges which
may cause or lead to the release of wastes to the environment, a threat to human health, or a
nuisance. The Permittee shall maintain an inspection log or summary including at least the
date and time of inspection, observations made, and any maintenance, repairs, or corrective
actions taken by the Permittee. This log of inspections shall be maintained by the Permittee
for a period of three years from the date of the inspection and shall be made available to the
Division of Water Quality or other permitting authority, upon request.
3. Any duly authorized officer, employee, or representative of the Division of Water Quality
may, upon presentation of credentials, enter and inspect any property, premises or place on
or related to the disposal site or facility at any reasonable time for the purpose of
determining compliance with this permit, may inspect or copy any records that must be
maintained under the terms and conditions of this permit, and may obtain samples of
groundwater, surface water, or leachate.
V I . GENERAL CONDITIONS
1. Issuance of this permit does not constitute approval for reimbursement from the Leaking
Petroleum Underground Storage Tank Cleanup Funds (15A NCAC 2P).
2. This permit shall become voidable unless the facilities are constructed in accordance with
the conditions of this permit, the approved plans and specifications, and other supporting
data.
3. This permit is effective only with respect to the nature and volume of wastes described in
the application and other supporting data.
4. This permit is not transferable. In the event there is a desire for the facilities to change
ownership, or there is a name change of the Permittee, a formal permit request must be
submitted to the Division of Water Quality accompanied by an application fee,
documentation from the parties involved, and other supporting materials as may be
appropriate. The approval of this request will be considered on its merits and may or may
not be approved.
