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.
Prior to beginning waste disposal operations, three (3) monitor wells, one (1) upgradient
and two (2) downgradient, shall be installed to monitor groundwater quality. The wells
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 of these
wells shall be approved by the Raleigh Regional Office and shall be constructed in
accordance with the conditions of this permit.
0
2. The three (3) monitor wells must be sampled initially after construction and thereafter every
April, August and December for the following parameters:
NO3 Chromium
TOC pH
Ammonia Nitrogen Chloride
Copper Total Suspended Solids
Water Level Total Dissolved Solids
Arsenic Phenol (per EPA Method 604)
Volatile Organic Compounds - (in December only by Method 1 or 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 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/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/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 results of the sampling and analysis shall be sent to the N.C. Division of
Environmental Management, P.O. Box 29535, Raleigh, N.C. 27626-0535 on Form GW-
59 (Compliance Monitoring Report Form) every May, September and January.
3. All wells that are constructed for the 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

4. The Raleigh Regional Office, telephone number (919) 571-4700 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 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.
5
5. Within sixty (60) days of completion of all monitoring wells, the permittee shall submit two
original copies of a scaled topographic map (scale no greater than 1:24,000) signed and
sealed by a professional engineer or a state licensed land surveyor that indicates all of the
following information:
a. the location and identity of each monitoring well,
b. the location of the waste disposal system,
c. the location of all property boundaries,
d, the latitude and longitude of each monitoring well,
e. the relative elevation of the top of the well casing (which shall be known as the
"measuring point"),
f. and the depth of water below the measuring point at the time the measuring point is
established.
All monitoring well locations and elevations shall be surveyed by a state licensed land
surveyor.
6. 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 associated GW-1 forms to the Permits and
Compliance Unit, Groundwater Section, P.O. Box 29535, Raleigh, N.C. 27626-0535.
7. 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 N.
C. General Statutes 143-215.6.
