must outline the actions taken or proposed to be taken to ensure that the problem
does not recur.
1. The three (3) existing monitor wells shall be sampled every April, August, and
December for the following parameters:
NO3 TDS
TOC pH
Ammonia Nitrogen Chloride
Water Level Total Coliforms
Total Suspended Solids
Volatile Organic Compounds - In December 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 - 600/4-881039
The measurement of water level must be made prior to sampling for the remaining
parameters.
7

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/l 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.
If any volatile organic compounds are detected by method 6230D, or the equivalent
method 502.2, then EPA methods 604 and 611 must also be run to detect other
organic compounds which may be present. The results of all analysis specified in
the monitoring requirements, including 644 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 Form GW -59 (Compliance Monitoring Report
Form) every May, September, and January.
2. The Compliance BQundgU, 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 143-215.6A. The sale of property, by the Permittee, which is
within or contiguous to the disposal system site may alter the location of the
Compliance Boundary.
For facilities permitted on or after December 30, 1983, the Compliance Boundary is
established at the lesser of 250 feet from the perimeter of the waste disposal area, 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 Division 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 EEVfEW B R , 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 plan 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.

3. No land application of waste activities shall be undertaken when the seasonal high
water table is less than three feet below land surface.
4. Any additional groundwater quality monitoring as deemed necessary by the
Division of Environmental Management shall be provided.
The Permittee or his designee shall inspect the sludge storage, transport, and
disposal facilities to prevent malfunctions and deterioration, operator errors and
discharges which may cause 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
