I ► ! _ U1 ..DUN
All monitoring wells abandoned on the site shall be abandoned in accordance with the
requirements of 15 NCAC 2C (N.C. Well Construction Standards).
2. The monitor wells must be sampled initially after construction and thereafter every March,
July, and November for the following parameters:
NO3 TDS
TOC pH
Ammonia Nitrogen Chloride
Water Level Total Coliforms
Orthophosphate
VOC - In November only (by Method 1 or Method 2 below)
Method 1: Method 6230D (Capillary - Column), "Standard Methods for the Examination
of Water and Wastewater", 17th edition, 1989.
Method 2: Method 502.2 " Methods for the Determination of Organic Compounds in
Drinking Water", United States Environmental Protection Agency - 600/4-88/039.
The measurement of water level must be made prior to sampling for the remaining
parameters.
The measuring points (top of well casing) of all monitoring wells shall be surveyed to
provide relative elevations of the measuring point for each of the monitoring wells. The
depth of water in each well shall be measured from the surveyed point on the top of the
casing.

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.
If any volatile organic compounds are detected by method 6230D, or the equivalent method
502.2, then EPA methods 604 and fill must also be run to detect other organic compounds
which may be present. The results of all analysis specified in the monitoring requirements,
including 604 and 611 if required, must be submitted simultaneously
The results of the sampling and analysis shall be sent to the N.C. Division of
Environmental Management on Foran GW -59 (Compliance Monitoring Report Form) every
April, August, and December.
3. The Compliance Boundary, delineated on the attached map for the disposal system is
specified by regulations in 15 NCAC 2L, Classifications and Water Quality Standards
applicable to the groundwater of North Carolina. An exceedance of Groundwater Quality
Standards beyond the Compliance Boundary is subject to penalty provisions applicable
under General Statute 143-215.6(1)a. The sale of property, by the Permittee, which is
within or contiguous to the disposal system site may alter location of the Compliance
Boundary.
For the subsurface disposal field, which was permitted prior to December 30, 1983, the
Compliance Boundary is established at the lesser of 500 feet from the subsurface disposal
field, or the property boundary, whichever is less.
For the rotary distributor unit, which was permitted on or after December 30, 1983, the
Compliance Boundary is established at the lesser of 250 feet from the rotary distributor
unit, or 50 feet within the property boundary.
If the title to any property which may affect the location of the Compliance Boundary is
changed, the Permittee shall notify the DEM Director within 14 days. The Director shall
then establish a modified Compliance Boundary which will be done as a modification to the
Permit.
The REVIEW BOUNDARY for the disposal system is specified by regulations in 15
NCAC 2L, Groundwater Classifications and Standards. A REVIEW BOUNDARY is
established around disposal systems midway between the Compliance Boundary and the
perimeter of the waste disposal area. When the concentration of any substance equals or
exceeds the maximum allowable concentration of that substance at the REVIEW
BOUNDARY, as determined by monitoring, the permittee shall either (i) demonstrate,
through predictive calculations or modeling, that natural site conditions, facility design and
operational controls will prevent a violation of standards at the Compliance Boundary; or,
(ii) submit a pian for the alteration of existing site conditions, facility design or operational
controls that will prevent a violation of standards at the Compliance Boundary, and
implement that plan upon its approval by the Director.
4. Any groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided.

1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
2. The Permittee or his designee shall inspect the wastewater treatment and disposal facilities

or lead to the release of wastes to the environment, a threat to human health, or a nuisance.
The Permittee shall keep an inspection log or summary including at least the date and time
of inspection, observations made, and any maintenance, repairs, or corrective actions
taken by the Permittee. This log of inspections shall be maintained by the Permittee for a
period of three years from the date of the inspection and shall be made available upon
request to the Division of Environmental Management or other permitting authority.
3. Any duly authorized officer, employee, or representative of the Division of Environmental
Management may, upon presentation of credentials, enter and inspect any property,
premises or place on or related to the disposal site and facility at any reasonable time for the
purpose of determining compliance with this permit; may inspect or copy any records that
must be kept under the terms and conditions of this permit; or may obtain samples of
groundwater, surface water, or leachate.
1. This permit shall become voidable unless the facilities are constructed in accordance with
the conditions of this permit, the approved plans, specifications and other supporting data.
2. This permit is effective only with respect to the nature and volume of wastes described in
the application and other supporting data.
3. This permit is not transferable. In the event there is a desire for the facilities to change
ownership, or there is a name change of the Permittee, a formal permit request must be
submitted to the Division of Environmental Management accompanied by an application
fee, documentation from the parties involved, and other supporting materials as may be
appropriate. The approval of this request will be considered on its merits and may or may
not be approved.
4. This wastewater treatment facility shall connect to a publicly owned areawide sewage
collection system within 180 days of its availability. All discharge of wastewater to the
rotary distribution fields shall cease at the time of the connection to the sewerage collection
system.
5. The annual administering and compliance fee must be paid by the Permittee within thirty
(30) days after being billed by the Division. Failure to pay the fee accordingly may cause
the Division to initiate action to revoke this permit as specified by 15 NCAC 2H .0205
