Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then
monthly monitoring will begin immediately until such time that a single test is passed. Upon passing,
this monthly test requirement will revert to quarterly in the months specified above.
Should any test data from either these monitoring requirements or tests performed by the North
Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit may
be re-opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival and appropriate environmental controls, shall constitute an invalid test and will
require immediate follow-up testing to be completed no later than the last day of the month following
the month of the initial monitoring.
A. (6) GROUNDWATER MONITORING
The permittee shall, upon written notice from the Director of the Division of Water Quality, conduct
groundwater monitoring as may be required to determine the compliance of this NPDES permitted
facility with the current groundwater Standards.
1. Monitor wells (2C, 4B, 5C, 6C, 7C, 8, 9, 10, 11, 12, 17, 18, and 19) shall be sampled every March
for the following parameters: Water Levels, pH, Arsenic, Iron,Total Dissolved Solids, Chlorides and
Selenium.
The measurement of water levels must be made prior to sampling for the remaining parameters. 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 to provide the
relative elevation of the measuring point for each monitoring well.
The results of the sampling and analyses shall be sent to:

2. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.
3. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in 15A NCAC 2L,
Groundwater Classifications and Standards. The Compliance Boundary for the disposal system
constructed prior to December 31, 1983 is established at either (1) 500 feet from the waste disposal
area, or(2) at the property boundary, whichever is closest to the waste disposal area. An exceedence
of Groundwater Quality Standards at or beyond the Compliance Boundary is subject to immediate
remediation action in addition to the penalty provisions applicable under General Statute 143-
215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the disposal systems
midway between the Compliance Boundary and the perimeter of the waste disposal area. Any
Permit NC00001422

exceedence of standards at the Review Boundary shall require remediation action on the part of the
permittee.
A. (7) DIKE INTEGRITY
The permittee shall check the dike areas for leaks by a visible inspection and shall report any seepage
detected.
A. (8) BEST MANAGEMENT PRACTICES PLAN
The Permittee shall continue to implement a Best Management Practices (BMP) Plan to control the
discharge of oils and the hazardous and toxic substances listed in 40 CFR, Part 117 and Tables II and
III of Appendix D to 40 CFR, Part 122, and shall maintain the Plan at the plant site and shall be
available for inspection by EPA and DWQ personnel

As specified by 40 CFR 423.13 (a), there shall be no discharge of polychlorinated biphenyl compounds
such as those commonly used for transformer fluid.
A. (11) BIOCIDE CONDITION
The permittee shall obtain authorization from the Division of Water Quality prior to utilizing any
biocide in the cooling water. The Permittee shall notify the Director in writing not later than ninety
(90) days prior to instituting use of any additional biocide used in treatment system which may be
toxic to aquatic life other than those previously reported to the Division of Water Quality. Such
notification shall include completion of Biocide Worksheet Form 101 and a map locating the discharge
point and receiving stream. Concentrations of chromium, copper, or zinc added to biocides shall not
exceed applicable water quality standards or action levels in the receiving stream, as determined by
calculations from the Biocide Worksheet Form 101 with Supplemental Metals Analysis worksheet.
A. (12) FISH STUDY AND MONITORING
The baseline study for the fish monitoring has been completed and approved (1999). This was
required based on the re-routing of Outfall 004 to the Cape Fear River. Fish tissue analysis will be
performed annually (after Outfall 004 is discharging to the Cape Fear River). Fish tissue monitoring
will only be completed if the ash pond discharges to the river for 120 days in a calendar year.All
contaminant data collected as part of this monitoring requirement will be reported within 4 months
after the calendar year in which the samples are taken. Should fish tissue levels indicate
concentrations of concern, the Division of Water Quality may require additional collection of
environmental data.
This monitoring plan is an enforceable part of the NPDES permit.
