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 established.
R

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 Iisted 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. The map shall also be surveyed
using the North American Datum of 1983 coordinate system and shall indicate the datum on the map.
All bearings or azimuths shall be based on either the true or NAD 83 grid meridian. If a Global
Positioning System (GPS) is used to determine the latitude and longitude of the horizontal control
monument, a GPS receiver that has the capability to perform differential GPS shall be used and all data
collected by the GPS receiver will be differentially corrected.
The neaps and any supporting documentation shall be sent to the Permits and Compliance Unit,

6. For the initial sampling of the well as specified elsewhere in the permit, the Permittee shall submit a
copy of the GW-I 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-I 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.
7. Monitor wells MW-1 and MW-2 shall be sampled initially after construction (and prior to waste
disposal operations) and thereafter every March, July, and November for the following parameters:
Water Level pH
Chloride Total Dissolved Solids (TDS)
Fecal Coliform Total Organic Carbon (TOC)
Nitrate -Nitrogen (NO3-N) Total Ammonia
Total Phosphorous
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.
If TOC concentrations greater than 10 mg/1 are detected in any downgradient monitoring well,
additional sampling and analysis must be conducted to identify the individual constituents comprising
this TOC concentration. If the TOC concentration as measured in the background monitor well
exceeds 10 mg/1, this concentration will be taken to represent the naturally occurring TOC
concentration. Any exceedances of this naturally occurring TOC concentration in the downgradient
wells shall be subject to the additional sampling and analysis as described above.
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 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.
Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.
