Groundwater Remediation Facilities
Edgecombe County
In accordance with modified groundwater comments received March 17, 1998, we are
forwarding herewith Permit No. WQ0014508, dated April 7, 1998, to Comer Oil Company for the
construction and operation of the subject groundwater remediation facility. The only modifications
being made at this time are waiving requirement of monitor well number 10, reducing the treatment
efficiency- to 95% and allowing a site -specific benchmark for the survey instead of requiring reference to
the North American Datum of 1983.
This permit shall be effective from the date of issuance until January 31, 2003, shall hereby void
Permit No. WQ0014508 issued February 27, 1998, 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.
One set of approved plans and specifications is being forwarded to you. If you have any
questions concerning the Groundwater Conditions or groundwater monitoring requirements, please
contact Ken Pohlig in the Groundwater Section at (919EPreston

or characteristic, such as 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;

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 groundwater treatment
and disposal system is not in compliance with any specified permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letter

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

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. 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.

MTBE using EPA Method 602-
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.

The results of the sampling and analysis must be received on Form GW-59 (Groundwater
Quality Monitoring: Compliance Report Form) by the Groundwater Section, Permits and

which will shut down the remediation system when the water level in either infiltration
gallery rises to within two feet of the ground surface.
5. The groundwater treatment system shall consistently achieve at least a 95% treatment
efficiency (i.e. remove 95% of the influent contaminants) prior to discharge to the
injection wells. if the treatment system fails to consistently achieve this standard,
additional treatment units or changes in operational methods, may be required.
6. The groundwater recovery, treatment and disposal system shall be inspected weekly. If it

is for the disposal system constructed after December 31, 1983 is established at either (1)
250 feet from the waste disposal area, or (2) 50 feet within 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
