c. the location of all property boundaries,
d. the latitude and longitude of the established horizontal control monument,
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

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.

(phone no. 910/ 771-4600) within 48 hours.
9. The groundwater treatment system shall consistently achieve a treatment efficiency w`iich
insures that waters discharged to the infiltration galleries is at or below Groundwater 2L
standards. If the treatment system fails to consistently achieve this standard, additional
treatment units or changes in operational methods, may be required.
10. Isoconcentration (lines connecting points of equal concentration) maps in both the vertical
and horizontal directions shall be developed for each constituent detected, in addition to
total VOC's, from the Groundwater monitoring data following each quarterly sampling
event. 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.
11. Flow measurement devices shall be installed to monitor the volumes pumped at each
recovery well. This information shall be tabulated and sent in with the rest of the
monitoring data on a quarterly basis.
12. Monitor wells MW-13 and MW-14 shall be sampled initially after construction for the
following parameters:
Water Level
EPA Method 602 to include Xylenes, METE, and 1-PE (Ispropyl Ether)
EPA Method 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 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.
For the initial sampling of the well 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

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 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] within 30 days of sample collection.

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
