Dear Mr. Gordon:
On March 27, 1996, the Division received a request, on behalf of The Community Bank, from Mr.
R. Edward Hedgecock, P.E., P.G., of BPA Environmental & Engineering, Inc., to amend several permit
conditions with regards to groundwater monitoring contained in the February 26, 1996, permit. Several
inquiries and a meeting between Mr. Hedgecock and the Division's Groundwater Section have taken place
to discuss the groundwater conditions and changes have been agreed upon without compromising
compliance and/or system performance. Several groundwater conditions (in permit section IV) have been
amended, in accordance with these discussions and the submitted request. Therefore, we are forwarding
herewith Permit No. WQ0011443 dated May 31, 1996, to the Community Bank for the construction and
operation of the subject groundwater remediation facility with the modifications as outlined in the request.
Additionally, the Division is aware that a petition for a contested case was filed for the February
26, 1996, permit. Since the permit is being amended in accordance with the request submitted, the
Division understands that a Notice of Withdrawal for this petition will be filed. A Notice of Withdrawal
form is attached for your use. Once filed, this permit shall be final and binding.
This permit shall be effective from the date of issuance until January 31, 2001, shall void Permit
No. WQ0011443 issued February 26, 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.

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 24 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

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 vertical and horizontal directions 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
to the Groundwater Section's Permits and Compliance Unit along with all other monitoring
data for that period on a quarterly basis for the duration of the permit.
7. Within sixty (60) days of completion of all monitoring wells, the permittee shall submit two
original copies of a scaled topographic map (scale no greater than V:100`) signed and
sealed by a professional engineer or a state licensed land surveyor that indicates all of the
following information:
a. the location and identity of each monitoring well,
b . the location of the waste disposal system,
c. the location of all property boundaries,
d. the relative elevation of the top of the well casing (which shall be known as the
"measuring point"), and
e. the depth of water below the measuring point at the time the measuring point is
established.
The maps and any supporting documentation shall be sent to the Groundwater Section,
N.C. Division of Environmental Management P.O. Box 29578 Raleigh, N.C. 27626-

8. All components of the groundwater recovery, treatment, and disposal system shall be
properly weather -proofed to prevent freezing and failure of the system.
9. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
10. 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.
11. The water levels in the nested pair P-1 (proposed) and MW-2 (existing), in conjunction
with the proposed well MW-9 and MW-10 (to be located between the gallery and the
McBride water supply well and between the gallery and the northern property boundary,
respectively), will be monitored upon startup as often as required until steady state
operation can be observed and maintained and, at a minimum, monthly thereafter (along
with water levels in all other non -pumping wells) to indicate any trendline 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 in the system design controls. The float sensor will be
set at approximately 1 foot above the stead -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, MW-9, and/or MW-10 water level measurements indicate a
tendency toward excessive mounding, the system pump rate will be adjusted by
individually modifying the pump rate of each of the recovery wells to preclude offsite radial
flow of contaminants and maintain capture of the plume.
12. 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 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.
13. 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-1 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.
14. 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.
15. 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 Environmental Management or other permitting authority, upon request.
