4. Within thirty days of completion of all well construction activities, a certification must be received
from a professional engineer certifying that the monitoring wells are located and constructed in
accordance with the Well Construction Standards (15A NCAC 2C) and this permit. This certification
should be submitted with copies of the Well Completion Form (GW-1) for each well. Mail this
certification and the associated GW-1 forms to the Permits and Compliance Unit, Groundwater Section,
P.O. Box 29578, Raleigh, NC, 27626-0578.
Within sixty days of completion of all monitoring wells, thePermittee shall submit two original copies
of a scaled topographic map (scale no greater than 1":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 all components of the waste disposal system,
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 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 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. 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 maps and any supporting documentation shall be sent to the Permits and Compliance Unit,
Groundwater Section, P.O. Box 29578, Raleigh, NC, 27626-0578.
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-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.
Monitor wells MW-I 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/l, 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.
8. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.
The COMPLIANCE BOUNDARY for the reclaimed water disposal system (including the wastewater
treatment facility, the irrigation pond, and the spray fields) is specified by regulations in 15A NCAC
2L, Groundwater Classifications and Standards. For disposal systems using reclaimed water,
Regulation 15A 2H .0219 (k) specifies that both the Compliance Boundary and Review Boundary are
established at the property boundary. 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 disposal

The following deflnhions shall apply throughout this Subchaptar.
(1) Activated Carbon Beds. A physlcal/chemical method for reducing soluble organic malarial from wastewater efffuerd; The cotumn-type beds used In this
method will have a flow rate varying from two to eight gallons per minute per square toot and may be either upflow or downflow carbon beds. Carbon may or
may not be regenerated on the wastewater treatment plant site;
(2) Aerated Lagoons. A basin In which alf solids are rnafntalnod In suspension and by which biological oxldatlon or organic matter is reduced through artificially
accelerated transfer of oxygen on a flow -through basis;
(3) Aeration. A process of bringing about intimate contact between air or high purity oxygen In a liquid by spraying, agitation or ditluslon;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 16 hours.
(4) Agriculturally managed sha. Any she on which a crop is produced, managed, and harvested (Crop includes grasses, grains, trees, etc.);
(5) Air Slripping. A process by which the ammonium ]on is first converted to dissolved ammonia (pH adjustment) with the ammonia then released to the
atmosphere by physical means, or other similar processes which remove petroleum products such as benzene, toluene, and xylene;
(6) Carbon Regeneration. The regeneration of exhausted carbon by the use of a furnace to provide extremely high temperatures which volatilize and oxidize the
absorbed Impurities;
V) Carbonaceous Stage. A stage of wastewater treatment designed to achieve 'secondary' effluent limits;
(8) Centrifuge. A mechanical device In which centrifugal force Is used to separate solids from liquids or to separate liquids of different densi',las;
(9) Chemical Addition Systems- The addition of chemkal(s) to wastewater at an application point for purposes of Improving solids removal, pH adjustment,
alkalinity control, etc.; the capability to experiment with different chemicals and different application points to achieve a specific result will be considered one
system; the capability to add chemical(s) to dua! units will be rated as one system; capabilty to add a chemical at a different application points for dMorant
purposes will result in the systems being rated as separate sysfams;
(10) Chemical Sludge Conditioning. The addhion of a chemical compound such as llme, tannic ch$orlde, or a polymer to wet sludge to coalesce the mass prior to
Its appFcation to a dewalering device;
(11) Closed Cycle Systems. Use of holding ponds or holding tanks for containment of wastewater containing Inorganic, non Toxic materials from sand, gravel,
crushed stone or other similar operallonc. Such systama shall carry a maximum of two points regardless of pumping facilities or any other appurtenances;
(12) Combined Removal of Carbonaceous BOD and Nhrogerous Removal by Nitrification- A single stage system required to achieve pemdt onluertt limits on BOD
and ammonla nitrogen within the same biological reactor,
(13) Dechlodrratlon. The parita! or complete reduction of residual chlorin In a liquid by any chemical or physical process;
(14) Denhrtficatlon Process. The conversion of nitrate-nitrogen to nitrogen gas;
