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 beginning waste disposal operations, five (5) monitor wells, one (1) upgradient
and four (4) downgradient, 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 Washington
Regional Office, and shall be constructed in accordance with the conditions of this permit.
2. The five (5) monitor 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
TOC
Ammonia Nitrogen
Water Level
Chemical Oxygen Demand
Volatile Organic Compounds -
TDS
pH
Chloride
Fecal Coliforms
Total Suspended Solids
In November only ( by
below)
Method 1 or Method 2
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 -
600l4-88/039

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.
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, 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) every
April, August, and December.
r TCLP
3. Between 60 and 90 days after system startup, a wastewater sample shall be taken at the
mid -point of the lagoon. The sample shall be analyzed for4oxicity test parameters, VOC,
and Total Trihalomethanes. The results of the sampling and analysis shall be sent to the
N.C. Division of Environmental Management, Groundwater Section, P.O. Box 29535
Raleigh, N.C. 27626-0535.
4. Based on the results of the analyses from condition number 3 above, the sampling and
monitoring schedule may be changed to ensure groundwater standards are not violated.
5. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
6. The interior surfaces of the lagoon shall be completely lined with a 36 -mil thick liner as
proposed in the submitted application plans.
7. All wells that are constructed for purposes of groundwater monitoring shall be constructed
in accordance with 15A NCAC 2C .0108 (Standards of Construction for Wells Other than
Water Supply) and any other state and local laws and regulations pertaining to well
construction.
8. The Washington Regional Office telephone number 919/ 946-6481 shall be notified at least
forty-eight (48) hours prior to the construction of any monitoring well so that an inspection
can be made of the monitoring well location. Such notification to the regional groundwater
supervisor shall be made during the normal office hours from 8:00 a.m. until 5:00 p.m. on
Monday through Friday, excluding State holidays.
9. Upon completion of all well construction activities, a certification must be received from a
professional engineer certifying that the monitoring wells are located and constructed in
accordance with the Well Construction Standards (15A NCAC 2C) and this permit. This
certification should be submitted with copies of the Well Completion Form (GW-1) for
each well. Mail this certification and the associated GW-1 forms to the Permits and
Compliance Unit, Groundwater Section, P.O. Box 29535, Raleigh, NC, 27626-0535.

10. For the initial sampling of the well as specified elsewhere in the permit, the permittee shall
submit a copy of the GW-1 form with the Compliance Monitoring Form (GW-59) for that
well. Compliance Monitoring Forms that do not include copies of the GW-1 form will be
returned to the permittee without being processed. Failure to submit these forms as required
by this permit may result in the initiation of enforcement activities pursuant to NC General
Statutes 143-215.6.
11. The S-mnlianc: Boundary delineated on the attached site plan for the disposal system is
specified by regulations in 15 NCAC 2L, Groundwater Classifications and Standards. An
exceedance of Groundwater Quality Standards beyond the Compliance Boundary is subject
to penalty provisions applicable under General Statute 143-215.6(1)a.
For facilities permitted on or after December 30, 1983, the Compliance Boundary is
established at the lesser of 250 feet from the lagoon and spray fields or 50 feet within the
property boundary.
Any sale or transfer of property which affects the location of the compliance boundary shall
be reported immediately to the Director. The permittee shall not transfer land within an
established compliance boundary unless the permittee has satisfied all the requirements of
15A NCAC 2L. 107 (e and f).
The REVIEW BOUNDARY delineated on the attached site plan for the disposal system is
specified by regulations in 15 NCAC 2L, Groundwater Classifications and Standards. A
REVIE BOUNDARY is established around disposal systems midway between the
Compliance Boundary and the perimeter of the waste disposal area. When the
