the actions taken or proposed to be taken to ensure that the problem does not recur.
r
1. Upon a determination by the Division that the facility operation has or will contravene
groundwater standards at or beyond the compliance boundary, the permittee will cease use
of this facility immediately upon receipt of notice of such contravention.
id

2. Prior to beginning waste disposal operations, three monitor wells, one (1) upgradient and
two (2) downgradient, must 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. The exact location and construction
details for these wells must be approved by the Washington Regional Office, from which a
well construction permit must be obtained.
3. The monitor wells must be sampled initially after construction (anal prior to waste disposal
operations) and thereafter monthly for the following parameter:
NO3 (10.0)
TOC
Ammonia Nitrogen
Water Level
Total Suspended Solids
Volatile Organic Compounds -
TDS (500.0)
pH (6.5-8.5 'standard units)
Chlorides (250.0)
Fecal Coliforms (1/100 ml)
Quarterly 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
600/4-88/039
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 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.
The numbers in parentheses represent the maximum allowable concentrations in
groundwater 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.
If TOC concentrations greater than 10 mg/1 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/1, 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 on Form GW -59 (Compliance Monitoring Report Form).

4. The Compliance Boundary 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 143-215.6(1)a.
The sale of property, by the Permittee, which is within or contiguous to the disposal
system site may alter 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 sprayfield, 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 DEM 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 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,
(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.
5. Any groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided.
1. Adequate inspection, maintenance, and cleaning shall be provided by the Craven County,
in conjunction with the Craven County Innovative and Alternative Demonstration Program,
to insure proper operation of the subject facilities.
