the dumping of the contents of a basin or tank, the known passage of a slug of
hazardous substance through the facility, or any other unusual circumstances;

b. Any process unit failure, due to known or unknown reasons, that renders the facility
incapable of adequate wastewater treatment, such as mechanical or electrical failures of
pumps, aerators, compressors, etc.;
c. Any failure of a pumping station, sewer line, or treatment facility resulting in a by-pass
directly to receiving waters without treatment of all or any portion of the influent to
such station or facility; or
d. Any time that self -monitoring information indicates that the facility is not in compliance
with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within 15 days following first knowledge of the occurrence. This report must outline
the actions taken or proposed to be taken to ensure that the problem does not recur.
IV. GROUNDWATER REQUIREMENTS
1. The groundwater treatment system shall consistently achieve Class GA Groundwater
Standards in the treated effluent, as outlined under Title 15A, Subchapter 2L, Section
.0212(g), prior to discharge to the injection wells. The treated water discharged into the
injection wells must not violate the Class GA Groundwater Quality Standards for any
constituent beyond the Compliance Boundary, nor cause the migration of contamination
into unaffected areas. If the treatment system fails to consistently achieve these standards,
additional treatment units or changes in operational methods may be required.
2. Monitor wells MW-1, MW-2, MW-3, MW-4, MW-5, MW-6, MW-7, MW-10, MW-II
and MW-12 shall be sampled prior to waste disposal operations and thereafter every
March, June, September, and December for the following parameters:
PH Water Level
Benzene Ethylbenzene
MTBE Xylenes
Toluene EDB
Naphthalene
The analysis for hydrocarbon compounds are to be performed by EPA Methods 602 and
610.
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 pumping water level in the recovery well will also be measured during these sampling
events, and the pumping water level data will be recorded and kept at the site.
The results of the sampling and analysis shall be sent to the Groundwater Section, Permits
and Compliance Unit, P.O. Box 29535 Raleigh, N.C. 27626-0535 on Form GW-59
[Compliance Monitoring Report Form] every April, July, October, and January.
3. The two injection wells shall be constructed of PVC casing and the screened interval of
each well shall be located from 5 feet to 35 feet below land surface. These wells- shall be
six inches in diameter. The Wilmington Regional Groundwater Supervisor at the
Wilmington Regional Office, telephone [phone], shall be notified at least 48 hours
prior to the construction of any extraction or injection well so that an inspection can be
made of the 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 holidays.
3

4. The two injection wells will each be equipped with a float -activated high-level shutoff
device which will shut down the remediation system when the water level in the well rises
to within four feet of the ground surface. The shutoff device will be designed such that the
remediation system will remain off until the water level in that well falls to an elevation six
feet below ground surface. The system will be wired so that either well may shut down the
system.
5. The remediation system will be equipped with an electronic monitor which automatically
records the time and date of every system shutdown event. If more than six float -activated
shutdowns are recorded during a consecutive 30-day period, the system flowrate will be
reduced by 10% of its rate at that time. If the situation persists after the flowrate has been
reduced, further reductions in the flowrate may be required.
6. Flow measurement devices shall be installed to monitor the volumes injected at each well.
Also each wellhead shall be equipped to measure the injection pressure at the screened
interval.
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. Prior to operation of the groundwater remediation system, the permittee shall certify the
mechanical integrity of the injection wells as defined by 15A NCAC 2C .0207.
Additionally, an engineering certification shall be provided stating that the injection wells
have been constructed in accordance with 15A NCAC 2C .0200 and the conditions of this
permit. This certification shall be forwarded to the Groundwater Section Permits Unit,
P.O. Box 29535, Raleigh, NC, 27626 prior to operation of the system.
9. Pursuant to rule 15A NCAC 2C .0211(g), injection may not commence until construction
of the injection wells are completed, the permittee has submitted notice of completion of
construction to the Wilmington Regional Office, and the regional office staff has inspected
or otherwise reviewed the injection well and finds it in compliance with the permit. If the
permittee has not received notice from the Wilmington Regional Office of the intent to
inspect or otherwise review the injection well within 10 days after the regional office has
received the notice, the permittee. may commence operation of the injection wells.
10. The influent and effluent from the treatment system shall be sampled immediately after
system start-up, once every two weeks for the first three months, and monthly thereafter
for EDB, BTEX, and MTBE by EPA Method 602, and for Naphthalene by EPA Method
610.
The results of the sampling and analysis shall be sent to the Groundwater Section, Permits
and Compliance Unit, P.O. Box 29535, Raleigh, NC 27626-0535 within 30 days of
sample collection.
11. For the initial sampling of the extraction well and injection wells 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.
12. The Permittee shall submit an annual report to the regional groundwater supervisor at the
Wilmington Regional Office outlining the injection volumes and pressures of injection
wells. This report may be submitted along with all other monitoring data.
