initially every March, July and November for the following parameters:
NO3 TDS
TOC pH
Ammonia Nitrogen Chloride
Water Level
Fecal Coliform
Volatile Organic Compounds - (In November only by Method 1 or 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", U.S. EPA - 600/4-88/039.
The measurement of water level must be made prior to sampling for the remaining
parameters. The depth of 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 relative elevations of the measuring point for each of the monitoring wells.
5

If TOC concentrations greater than 10 mg/I 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 back r� o� 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 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 P.O. Box 29535 Raleigh, NC 27626-0535 on Form GW -59
(Compliance Monitoring Report Form) every April, August and December.
3. The CompHance-Boundary for the disposal system is specified by regulations in 15A
NCAC 2L, Groundwater Classifications and Standards. An exceedance of Groundwater
Quality Standards beyond the Compliance Boundary is subject to the 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 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 waste disposal area, or 50 feet within the
property boundary.
The REVIEW BOUNDARY for the disposal system is specified by regulations in 15A
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,
(h) 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.
4. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
V. INSPECTIONS
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
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
