Persons reporting such occurrences by telephone shall also file a written report in letter
form within five (5) days following first knowledge of the occurrence. This report must
outline the actions taken or proposed to be taken to ensure that the problem does not recur.
IV. GROUNDWATER REQUIREMENTS
Monitor wells MW-22, MW-25, and MW-26 shall be sampled every July for Volatile
Organic Compounds - by Method 6230D below.
Method 6230D (Capillary - Column), "Standard Methods For The Examination -of
Water and Wastewater", 17th ed., 1989
Monitor wells MW-4, MW-6, MW-7, MW-9, MW-15, MW-16, MW-22, MW-25 and
MW-26 shall be sampled every March, July and October for the following parameters:
Water Level pH
Total Dissolved Solids Sulfatea
Ammonia Nitrogen Nitratea
Nitritea Formaldehyde
Hexamine Total Suspended Solidsb
Total Organic Carbon
a These parameters shall only be sampled on monitor wells MW-9 and MW-16 at the same
frequency as stated above.
b These parameters shall only be sampled on monitor well MW-7 at the same frequency as
stated above.
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.
4

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/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, then the Wilmington
Regional Office Groundwater Supervisor, telephone number 910-395-3900, must be
contacted immediately for further instructions regarding any additional follow-up analyses
required. The results of all initial and follow-up analyses must be submitted
simultaneously.
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.
3. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
4. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary is
for the disposal system constructed after December 31, 1983 is established at either (1) 250
feet from the waste disposal area, or (2) 50 feet within the property boundary, whichever is
closest to the waste disposal area. 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 systems midway between the Compliance Boundary and the perimeter of the
waste disposal area. Any exceedance of standards at the Review Boundary shall require
remediation action on the part of the permittee.
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 groundwater recovery and treatment
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 maintain 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
