Persons reporting such occurrences by telephone shall also file a written report in

must outline the actions taken or proposed to be taken to ensure that the problem
does not reoccur.
GROUNDWATER REQJ1IREMENTS
1. The six (6) existing monitoring wells must be sampled initially after construction
(and prior to waste disposal operations) and thereafter every March, July, and
November for the following parameters:
NO3 TOX (in November Only)
TOC pH ( 6.5-5.5 standard units)
Total Ammonia Chloride
Total Coliforms Water Levels
_ 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 relative to mean sea level (M.S.L.). The depth of the water in each well
shall be measured from the surveyed point on the top of the casing. The Water level
elevations shall then be determined relative to (M.S.L.).
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 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 numbers in parentheses represent the maximum allowable concentrations in
gioundwilter for the various analytical parameters, as specified in 15 NCAC 2L
[Groundwater Classifications and Standards]. Unless otherwise noted, the
concentrations are given in parts per million.
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
Forth) every April, August, and December.
2. Any groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided.

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 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
