pass directly to receiving waters without treatment of all or any portion of the
influent to such station or facility.
d. Any time that self -monitoring information indicates that the facility has gone out of
compliance with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in letter
form within 15 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.
1. Prior to the operation of the storage lagoon, one additional monitoring well shall be
installed to monitor groundwater quality. The well(s) shall be constructed such that the
water level in the well is never above or below the screened (open) portion of the well at
any time during the year. However, the exact location and construction details for these
wells shall be approved by the Wilmington Regional Office, from which a well
construction permit must be obtained.
2. The new monitor well shall be sampled initially after construction for the parameters below.
All monitoring wells (5 existing wells and 1 new well) shall be sampled every March, July,
and November for the following parameters:
NO3
TOC
Ammonia Nitrogen
Water Level
Orthophosphate
NO2
Volatile Organic Compounds -
MR
pH
Chlorides
Fecal Coliforms
Total Suspended Solids
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 -

3. The measurement of water level must be made prior to sampling for the remaining
parameters.
4. 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.
5. If TOC concentrations greater than 10 riig/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 bagk_==d 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.
6. 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.
7. 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
April, August, and December.
8. The lagoon shall have a liner of natural material at least one (1) foot in thickness,
compacted to 95% proctor standard dry density and installed and compacted in layers no
thicker than six inches, with a hydraulic conductivity of no greater than 1 x 10-6
centimeters per second when compacted. Following installation and inspection of the
lagoon liner, and prior to waste disposal operations, verification of the liner's compliance
with hydraulic conductivity and thickness specifications must be provided to the Division
of Environmental Management, Groundwater Section, by the project engineer.
9. The Compliance Bundary 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 location of the Compliance Boundary.
10. For facilities permitted on or after December 30, 1983, the Compliance Boundary is
established at the lesser of 250 feet from the lagoons, or 50 feet within the property
boundary.
11. 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.
W

12. The RE IE BOUNDARY for the disposal system is specified by regulations in 15
NCAC 2L, Groundwater Classifications and Standards. A REVIEW BQ hIDARY 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 E.EVIEW
B—O NDARY, as determined by monitoring, the permmittee 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,
