activities and the well(s) must be abandoned according to the North Carolina Well Construction
Standards (15A NCAC 2C .0113) and local county rules. Within thirty (30) days of abandonment,
a Well Abandonment Record (GW-30 form) shall be completed for each well abandoned and
mailed to the address listed in the "Reporting /Documentation" section of the Groundwater
Requirements. According to 2L .0113, the owner of the well has the right to petition for a

2. SampIing Criteria:
a. Monitor wells MW-I, MW-3A, MW-6, MW-8, and MW-9 (depicted on Figure 2) shall be
sampled every February, June and October for the parameters listed below. Prior to sampling the
parameters, the measurement of water levels must be taken. The depth to 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 relative to a common datum.
Water level Fecal Coliforms
PH Nitrate (NO3-N)
Total Disolved Solids (TDS) Chloride
Total Ammonia Nitrogen (NH3-N) Total Organic Carbon (TOC)
Volatile Organic Compounds (VOC) sampled in November
b. For Volatile Organic Compounds (VOCs) sampled in November, use only one of the following
methods:
2) Standard Method 6230D, Practical Quantitative Limit (PQL) at 0.5 ug/L or less
3) Standard Method 6210, PQL at 0.5 ug/L or less
4) EPA Method 8021, Low Concentration, PQL at 0.5 ug/L or less
5) EPA Method 8260, Low Concentration;, PQL at 0.5 ug/L or less
6) Another method with prior approval by the Groundwater Section Chief.
Any of the referenced methods used for VOCs must a minimum, include all the constituents listed
in Table VIH of Standard Method 6230D. Any method used must provide a PQL of 0.5 ug/L or
less, which must be supported by laboratory proficiency studies as required by the DWQ
Laboratory Certification Unit. Any constituents detected above the Method Detection Limit
(MDL) but below the PQL of 0.5 ug/L must be qualified (estimated) and reported.
For Total Organic Carbon (TOC), if Concentrations greater than 10 mg/1 are detected in any down -
gradient monitoring well, additional sampling and analysis must be conducted to identify the
indivi8dual constituents comprising this TOC concentration. If the TOC concentration as
measured in the background monitor well exceeds 10mg/l, this concentration will be taken to
represent the naturally occurring TOC concentration. Any exceedances of this naturally occurring
TOC concentration in the down -gradient wells shall be subject to the additional sampling and
analysis as described above.
d. Any laboratory selected to analyze parameters must be Division of Water Quality (DWQ) certified
for those parameters required.
Reporting I Documentation:
a. All reports and documentation (GW-30, GW-59) shall be mailed to the following address:
Groundwater Section
Permits and Compliance Unit
1636 Mail Service Center
Raleigh, NC 27699-1636
b. The results of the sampling and analysis must be received on Form GW-59 (Groundwater Quality
Monitoring: Compliance Report Form) by the Groundwater Section (address listed in the
"Reporting/Documentation" section of the Groundwater Requirements), on or before the last
working day of the month following the sampling month, The data of all groundwater sampling
analyses required by the permit conditions must be reported using the most recent GW-59 form
along with attached copies of the laboratory analyses.

4. Applicable Boundaries:
a. The COMPLLANCE BOUNDARY for the disposal system is specified by regulations in 15A
NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary for the
disposal system individually permitted prior to December 30, 1983 is established at either 500 feet

disposal area. An exceedance of Groundwater Quality Standards at or beyond the Compliance
Boundary is subject to immediate remediation action according to 15A NCAC 2L .0106(d)(2).
b. The REVIEW BOUNDARY is established around the disposal systems midway between the
Compliance Boundary and the perimeter of the waste disposal area. Any exceedance of standards
at the Review Boundary shall require action in accordance with 15A NCAC 2L .0106(d)(1).
5.Additional Requirements:
a. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.

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 or other permitting authority.

there is a name change of the Permittee, a formal permit request must be submitted to the Division
accompanied by an application fee, documentation from the parties involved, and other supporting
materials as may be appropriate. The approval of this request will be considered on its merits and
may or may not be approved.
