2. Discharge of blowdown from the cooling system shall be limited to the minimum discharge of recirculating water
necessary for the purpose of discharging materials contained in the water, the further built-up of which would cause
concentrations in amounts exceeding limitations established by best engineering practices. The permittee may discharge
cooling water to the auxiliary reservoir in compliance with condition A. (20) of this permit.
3. Neither free available chlorine nor total residual chlorine may be discharged from any unit for more than two hours in any
one day and not more than one unit in any plant may discharge free available or total residual chlorine at any one time
unless the utility can demonstrate to the Director that the units in question cannot operate at or below this level of
chlorination. The permittee shall record and report times of release as part of the monthly monitor report. Free available
chlorine shall be a daily average and daily maximum.
4. Samples shall be multiple grabs at the tower which shall consists of grab samples collected at the approximate beginning
of the total residual chlorine discharge and once every 15 minutes thereafter until the end of the total residual chlorine
discharge. For the purpose of this permit, daily average (as it relates to the chlorination period) shall mean the average
over any total residual chlorine discharge period. Monitoring only applicable if the facility adds chlorine to water that is
eventually discharged.
5. These limitations and monitoring requirements apply only if these materials are added for cooling tower maintenance by
the permittee. There shall be no discharge of detectable amounts of the 126 priority pollutants (40 CFR 423 Appendix A)
contained in chemicals added for cooling tower maintenance except for Total Chromium and Total Zinc. Compliance with
the limitations for the 126 pollutants may be determined by engineering calculations which demonstrate that the regulated
pollutants are not detectable in the discharge by the analytical methods in 40 CFR 136.

A. (8) ACUTE TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY) OUTFALLS 006 AND 007
[15A NCAC 02B .0200 et seq.]
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North Carolina Procedure
Document entitled "Pass/Fail Methodology For Determining Acute Toxicity In A Single Effluent Concentration" (Revised
December 2010 or subsequent versions). The monitoring shall be performed as a Fathead Minnow (Pimephales promelas) 24
hour static test. The effluent concentration at which there may be at no time significant acute mortality is 90% (defined as
treatment two in the procedure document). The tests will be performed during the months of February, May, August, and
November. These months signify the first month of each three month toxicity testing quarter assigned to the facility.
Effluent sampling for this testing must be obtained during representative effluent discharge and shall be performed at the
NPDES permitted final effluent discharge below all treatment processes.
Page 7 of 16

NPDES Permit NC0039586
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.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form
(MR-1) for the month in which it was performed, using the parameter code TGE6C. Additionally, DWR Form AT-2 (original)
is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Or, results can be sent to the email: [e-mail].
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30 days after the end of
the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in association
with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity sample must be
measured and reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee
will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit
number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the
form. The report shall be submitted to the Water Sciences Section at the address cited 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. Assessment of toxicity compliance is based on the toxicity testing quarter, which is the
three month time interval that begins on the first day of the month in which toxicity testing is required by this permit and
continues until the fmal day of the third month.
Should any test data from either these monitoring requirements or tests performed by the North Carolina Division of Water
Resources 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. (9) COPPER LIMITS EVALUATION (OUTFALL 006) [G.S. 143-215.1(b)]
The Total Copper limits have been eliminated for this permit term only. If the facility desires to extend WER based copper
limits elimination for the next permit term, the facility shall conduct a new WER study. The new WER study shall be
conducted per EPA guidance for WER evaluations in lakes, to do a mixing zone analysis (MZA) in conjunction with WER
study, which incorporates effluent mixed with site water at a ratio to be determined by the near -field dilution from the mixing
zone in order to derive a WER that reflects mixing of the effluent with the receiving water. This would factor in all the
variables beyond hardness that affect copper toxicity (e.g. dissolved organic carbon, pH, cations/anions that form copper
complexes, etc.) inherent in the combined effluent and receiving water.
A. (10) BIOCIDES [G.S. 143-215, 143-215.1]
The permittee shall not use any biocides except those approved in conjunction with the permit application. The permittee shall
notify the Director in writing not later than ninety (90) days prior to instituting use of any additional biocide used in cooling

EPA plans to establish a website that will also link to the appropriate electronic reporting tool for each type of electronic
submission and for each state. Instructions on how to access and use the appropriate electronic reporting tool will be
available as well. Information on EPA's NPDES Electronic Reporting Rule is found at:
http://www2. epa. gov/compliance/fmal-national-pollutant-discharge-elimination-system-npdes-electronic-reporting-rule.
Electronic submissions must start by the dates listed in the "Reporting Requirements" section above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an electronic reporting
waiver, a permittee must first submit an electronic reporting waiver request to the Division. Requests for temporary
electronic reporting waivers must be submitted in writing to the Division for written approval at least sixty (60) days prior
to the date the facility would be required under this permit to begin submitting monitoring data and reports. The duration
of a temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data and reports shall
be submitted electronically to the Division unless the permittee re -applies for and is granted a new temporary electronic
reporting waiver by the Division. Approved electronic reporting waivers are not transferrable. Only permittees with an
approved reporting waiver request may submit monitoring data and reports on paper to the Division for the period that the
approved reporting waiver request is effective.

A. (21) STORMWATER MONITORING REQUIREMENTS [G.S. 143-215.1(a) et seq., 15A NCAC 02h .0126 et seq.]
Stormwater conditions under this section will expire on the effective date when an individual stormwater permit is issued to the
facility by the Division of Energy, Mineral and Land Resources.
1. Qualitative Monitoring
Qualitative monitoring requires a qualitative inspection of each stormwater outfall, regardless of representative outfall status,
for the purpose of evaluating the effectiveness of the Stormwater Pollution Prevention Plan (SPPP) and assessing new sources
of stormwater pollution. No analytical tests are required. Qualitative monitoring of stormwater outfalls does not need to be
performed during a representative storm event.

2. Stormwater Pollution Prevention Plan
The permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as the Plan. The Plan shall be
considered public information in accordance with Part VI, Section E.10 of this permit. The Permittee is not required to submit a
copy of the Plan to the Division. The Plan shall be available at the permitted facility for Division staff or public review upon
request. The Plan shall include, at a minimum, the following items:
a. Site Plan: The site plan shall provide a description of the physical facility and the potential pollutant sources which
may be expected to contribute to contamination of regulated stormwater discharges. The site plan shall contain the
following:
(1) A general location map (USGS quadrangle map, or appropriately drafted equivalent map), showing the
facility's location in relation to transportation routes and surface waters, and the name of the receiving water(s)
to which the stormwater outfall(s) discharges. If the discharge is to a municipal separate storm sewer system,
the name of the municipality and the ultimate receiving waters, and accurate latitude and longitude of the
point(s) of discharge must be shown.
(2) A narrative description of storage practices, loading and unloading activities, outdoor process areas, dust or
particulate generating or control processes, and waste disposal practices.
(3)
A site map (or series of maps) drawn to scale with the distance legend indicating location of industrial activities
(including storage of materials, disposal areas, process areas, and loading and unloading areas), drainage
structures, drainage areas for each outfall and activities occurring in the drainage area, building locations and
impervious surfaces, the percentage of each drainage area that is impervious. For each outfall, a narrative
Page 12 of 16

NPDES Permit NC0039586
description of the potential pollutants which could be expected to be present in the regulated stormwater
discharge.
(4) A list of significant spills or leaks of pollutants that have occurred at the facility during the 3 previous years
and any corrective actions taken to mitigate spill impacts.
(5)
Certification that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges.
The certification statement will be signed in accordance with the requirements found in Part VI, Section B.11.
b. Stormwater Management Plan: The stormwater management plan shall contain a narrative description of the materials
management practices employed which control or minimize the exposure of significant materials to stormwater,
including structural and non-structural measures. The stormwater management plan, at a minimum, shall incorporate
the following:
(1) A study addressing the technical and economic feasibility of changing the methods of operations and/or storage
practices to eliminate or reduce exposure of materials and processes to stormwater. Wherever practicable the
permittee should consider covering storage areas, material handling operations, manufacturing or fueling
operations to prevent materials exposure to stormwater. In areas where elimination of exposure is not
practicable, the stormwater management plan shall document the feasibility of diverting the stormwater runoff
away from areas of potential contamination
(2) A schedule to provide secondary containment for bulk storage of liquid materials, storage of Section 313 of
Title III of the Superfund Amendments and Reauthorization Act (SARA) water priority chemicals, or storage
of hazardous materials to prevent leaks and spills from contaminating stormwater runoff. If the secondary
containment devices are connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices [which shall be secured with a locking
mechanism] and any stormwater that accumulates in the containment area shall be at a minimum visually
observed prior to release of the accumulated stormwater. Accumulated stormwater shall be released if found
to be uncontaminated. Records documenting the individual making the observation, the description of the
accumulated stormwater and the date and time of the release shall be kept for a period of five years.
(3)
A narrative description of Best Management Practices (BMPs) to be considered such as, but not limited to, oil
and grease separation, debris control, vegetative filter strips, infiltration and stormwater detention or retention,
where necessary. The need for structural BMPs shall be based on the assessment of potential of sources
contributing significant quantities of pollutants to stormwater discharges and data collected through monitoring
of stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and measures to be taken to limit or prevent
erosion associated with the stormwater systems.
c. Spill Prevention and Response Plan: The Spill Prevention and Response Plan shall incorporate a risk assessment of
potential pollutant sources based on a materials inventory of the facility. Facility personnel (or team) responsible for
implementing the plan shall be identified in the plan. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or exposure of materials associated
with the facility operations.
d. Preventative Maintenance and Good Housekeeping Program: A preventative maintenance program shall be
developed. The program shall document schedules of inspections and maintenance activities of stormwater control
systems, plant equipment and systems. Inspection of material handling areas and regular cleaning schedules of these
areas shall be incorporated into the program.
e. Training schedules shall be developed and training provided at a minimum on an annual basis on proper spill response
and cleanup procedures and preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff. Facility personnel (or team) responsible for
implementing the training shall be identified in the plan.
f. The Stormwater Pollution Prevention Plan shall identify a specific position(s) responsible for the overall coordination,
development, implementation, and revision to the Plan. Responsibilities for all components of the Plan shall be
documented and position(s) assignments provided.

g.
Plan Amendment: The permittee shall amend the Plan whenever there is a change in design, construction, operation,
or maintenance which has a significant effect on the potential for the discharge of pollutants via a point source to
surface waters. The Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual basis.
The director may notify the permittee when the Plan does not meet one or more of the minimum requirements of the
permit. Within 30 days of such notice, the permittee shall submit a time schedule to the Director for modifying the Plan
to meet minimum requirements. The permittee shall provide certification in writing (in accordance with Part VI, Section
B.11.) to the Director that the changes have been made.
h. Facility Inspections: Inspections of the facility and all stormwater systems shall occur at a minimum on a semiannual
schedule, once in the fall (September - November) and once during the spring (April - June). The inspection and any
subsequent maintenance activities performed shall be documented, recording date and time of inspection, individual(s)
making the inspection and a narrative description of the facility's stormwater control systems, plant equipment and
systems. Records of these inspections shall be incorporated into the Stormwater Pollution Prevention Plan.
Visual monitoring as required in Part I, Section A(8) Stormwater Monitoring Requirements/Qualitative Monitoring shall
be performed in addition to facility inspections.
Implementation: Implementation of the Plan shall include documentation of all monitoring, measurements, inspections,
maintenance activities and training provided to employees, including the log of the sampling data. Activities taken to
implement BMPs associated with the industrial activities, including vehicle maintenance activities, must also be
recorded. All required documentation shall be kept on -site for a period of five years and made available to the Director
or his authorized representative immediately upon request.
3. Stormwater Minimum Monitoring and Reporting Requirements
Minimum monitoring and reporting requirements are as follows unless otherwise approved in writing by the Director:
a. If a facility has multiple discharge locations with substantially identical stormwater discharges that are required to be
sampled, the permittee may petition the Director for representative outfall status. If it is established that the stormwater
discharges are substantially identical and the permittee is granted representative outfall status, then sampling
requirements may be performed at a reduced number of outfalls.
b. Qualitative monitoring for color, odor, solids, foam, outfall staining, visible sheens and dry weather flow shall be
performed at all stormwater discharge outfall locations. All qualitative monitoring shall be documented and records
maintained with the Stormwater Pollution Prevention Plan. The initial qualitative monitoring event shall be performed
simultaneously with the first analytical monitoring event and documentation of only this initial qualitative monitoring
event shall be submitted along with the required analytical monitoring submittal.
c. If the stormwater runoff is controlled by a detention pond, the following sampling requirements shall apply:
(1) If the detention pond detains the runoff generated by one inch of rainfall for 24 hours, visual observations for
color, foam, outfall staining, visible sheens and dry weather flow are required, but analytical sampling shall
not be required.
(2) If the detention pond discharges only in response to a storm event exceeding a 25-year, 24-hour storm, the
pond shall be considered a non -discharging stormwater control system and not subject to NPDES requirements,
unless the discharge causes a violation of water quality standards.
d. Samples analyzed in accordance with the terms of this permit shall be submitted on forms approved by the Director no
later than January 31 for the previous year in which sampling was required to be performed.
e. Analytical results from sampling during the fmal year of the permit term shall be submitted with the permit renewal
application.
f. This permit regulates stormwater discharges associated with industrial activity. Non-stormwater discharges which shall
be allowed in the stormwater conveyance system are:
Page 14 of 16

NPDES Permit NC0039586
(1) All other discharges that are authorized by an NPDES permit.
(2) Foundation drains, air -conditioner condensate without added chemicals, springs, waterline and fire hydrant
flushing, water from footing drains, flows from riparian habitats and wetlands, fire -fighting training and fire
system testing.
(3)
Discharges resulting from fire -fighting and uncontaminated discharges resulting from fire -fighting training and
associate fire system testing.
If the storm event monitored and reported in accordance with this permit coincides with a non-stormwater discharge,
the permittee shall separately monitor and report all parameters as required under the non-stormwater portion of this
permit and provide this information with the stormwater discharge monitoring report.
