Dear Mr. Barton:
Division personnel have reviewed and approved your application for renewal of the subject permit
Accordingly, we are forwarding the attached NPDES permit. This permit is issued pursuant to the requirements
of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and
the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently amended).
There was one addition to the draft permit requirements Because your discharge is upstream and within
5 miles of the Sanford WTP intake, the Division of Water Resources/Public Water Supply Section has alerted
the Division that monthly monitoring for effluent fecal coliform must be added to the final peiuiit.
Summary of Changes in Final Permit from Existing Permit
1. Outfall 001: Monthly monitoring for fecal coliform was added. Based on discharge location upstream
from Sanford WTP intake.
2. Outfall 001: Monitoring for chromium, copper, cyanide, lead, and zinc was removed. Based on
Reasonable Potential Analyses strategy.
3. Outfall 001: New limits for BOD and TSS were applied based on process wastewater flow and domestic
wastewater flow. Based on 40 CFR 414 Subpart E guidance and domestic wastewater secondary
treatment standards
4. Outfall 001: New limits for effluent characteristic in A. (2) were applied based on process wastewater
flow. Based on 40 CFR 414 Subpart I guidance.
5. Outfall 001: Annual monitoring for salinity, total dissolved solids, total arsenic, total chloride, and total
iron will be added. Based on WTP guidance for reverse osmosis wastewater.
6. Outfall 001: Supplement to Cover Sheet narratives and Special condition A. (3) CHRONIC TOXICITY
PERMIT LIMIT narrative will be updated. Technical updates.

A. (3) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 0.39%.
The permit holder shall perform at a minimum quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or
subsequent versions or North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised -December 2010) or subsequent versions. 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 shall be performed at
the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below
the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the
two following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Drschaige Monitoring ,Form (MR-1) for the months in which tests were performed, using the
parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally,
DWQ Form AT-3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental 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 accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. 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 Environmental Sciences Section at the address cited above.
•
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month. 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 final day of the third
month.

quantities of pollutants to stormwater discharges and data collected through monitoring
of stormwater discharges. The BMP Summary shall include a written record of the
specific rationale for installation and implementation of the selected site BMPs The
BMP Summary shall be reviewed and updated annually.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP) shall
incorporate an assessment of potential pollutant sources based on a materials inventory of the
facility Facility personnel (or the team) responsible for implementing the SPRP shall be
identified in a written list incorporated into the SPRP and signed and dated by each individual
acknowledging their responsibilities for 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. The SPRP must
be site stormwater specific. Therefore, an oil Spill Prevention Control and Countermeasure
plan (SPCC) may be a component of the SPRP, but may not be sufficient to completely address
the stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may
be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative maintenance and
good housekeeping program shall be developed. The program shall list all stonmwater control
systems, stormwater discharge outfalls, all on -site and adjacent surface waters and wetlands,
industrial activity areas (including material storage areas, material handling areas, disposal
areas, process areas, loading and unloading areas, and haul roads) all drainage features and
structures, and existing structural BMPs. The program shall establish schedules of inspections,
maintenance, and housekeeping activities of stormwater control systems, as well as facility
equipment, facility areas, and facility systems that present a potential for stormwater exposure
or stormwater pollution. Inspection of material handling areas and regular cleaning schedules
of these areas shall be incorporated into the program. Timely compliance with the established
schedules for inspections, maintenance, and housekeeping shall be recorded in writing and
maintained in the SPPP.
5. Employee Training. Training programs shall be developed and training provided at a minimum
on an annual basis for facility personnel with responsibilities for: spill response and cleanup,
preventative maintenance activities, and for 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, and their annual training shall be documented by
the signature of each employee trained.
6. Responsible Party. The Storruwater 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
assignments provided.

(Continued B. (3) STORMWATER POLLUTION PREVENTION PLAN)
7. 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 to surface waters. All aspects of the Stormwater Pollution Prevention
Plan shall be reviewed and updated on an annual basis. The annual update shall include an
updated list of significant spills or leaks of pollutants for the previous three years, or the
notation that no spills have occurred. The annual update shall include written re -certification
that the stormwater outfalls have been evaluated for the presence of non-stormwater discharges.
Each annual update shall include a documented re-evaluation of the effectiveness of the BMPs
listed in the BMP Summary of the Stormwater Management Plan.
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 II, Section B, Paragraph
11 to the Director that the changes have been made.
8. Facility Inspections Inspections of the facility and all stormwater systems shall occur as part of
the Preventative Maintenance and Good Housekeeping Program at a minimum on a semi-
annual schedule once during the first half of the year (January to June) and once during the
second half (July to December), with at least 60 days separating inspection dates (unless
performed more frequently than semi-annually). These facility inspections are different from,
and in addition to, the stormwater discharge characteristic monitoring required in special
conditions B.(4) and B (5) of this permit.
Implementation The permittee shall implement the Plan. 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 and of actions taken
to implement BMPs associated with the industrial activities, including vehicle maintenance
activities. Such documentation shall be kept on -site for a period of five years and made
available to the Director or the Director's authorized representative immediately upon request.
B. (4) ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges from Stormwater Discharge Outfalls 002, 003, and
004 shall be performed as specified in Table 1. All analytical monitoring shall be performed during a
representative storm event. The required monitoring will result in a minimum of ten analytical
samplings being conducted over the term of the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall.
The time between this storm event and the previous storm event measuring greater than 0.1
inches must be at least 72 hours. A single storm event may have a period of no precipitation of
up to 10 hours For example, if it rains but stops before producing any collectable discharge, a
sample may be collected if the next rain producing a discharge begins within 10 hours.

Footnotes:
1. Maintain semi-annual monitoring (or monthly, depending on Tier) during permit renewal process.
The applicant must continue semi-annual (or monthly, depending on Tier) monitoring until the
renewed is issued.
2 If no discharge occurs during the sampling period the permittee must submit a monitoring report
indicating "No Flow" within 30 days of the end of the sampling period.
The permittee shall report the analytical results from the first sample with valid results within the
monitoring period. The permittee shall compare monitoring results to the benchmark values in Table
1. The benchmark values in Table 1 are not permit limits but should be used as guidelines foi the
permittee's Stormwater Pollution Prevention Plan (SPPP). Exceedences of benchmark values require
the permittee to increase monitoring, increase management actions, increase record keeping, and/or
install stoimwater Best Management Practices (BMPs) in a tiered program. See below the descriptions
of Tier One, Tier Two, and Tier Three.
Tier One
If. The first valid sampling results are above a benchmark value, or outside of the benchmark range,
for any parameter at any outfall;
Then: The permittee shall:
1. Conduct.a stormwater management inspection of the facility within two weeks of receiving
sampling results.
2. Identify and evaluate possible causes of the benchmark value exceedence.
3. Identify potential and select the specific: source controls, operational controls, or physical
improvements to reduce concentrations of the parameters of concern, or to bring
concentrations within the benchmark range.
4. Implement the selected actions within two months of the inspection.
5. Record each instance of a Tier One response in the Stormwater Pollution Prevention Plan.
Include the date and value of the benchmark exceedence the inspection date, the personnel
conducting the inspection, the selected actions, and the date the selected actions were
implemented.

(Continued B (4) ANALYTICAL MONITORING REQUIREMENTS - Tier Two)
Tier Two
If: The first valid sampling results from two consecutive monitoring periods are above the
benchmark values, or outside of the benchmark range, for any specific parameter at a specific
discharge outfall;
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2 Immediately institute monthly monitoring for all parameters at every outfall where a sampling
result exceeded the benchmark value for two consecutive samples. Monthly (analytical and
qualitative) monitoring shall continue until three consecutive sample results are below the
benchmark values or within the benchmark range.
3. If no discharge occurs during the sampling period, the permittee is required to submit a
monthly monitoring report indicating "No Flow" to comply with reporting requirements
4. Maintain a record of the Tier Two response in the Stormwater Pollution Prevention Plan.
5. Continue Tier Two obligations (monthly monitoring, etc.) through the permit renewal process
if the term of this permit concludes before conditions are met to reduce monitoring.
Tier Three
If the valid sampling results required for the permit monitoring periods exceed the benchmark value,
or are outside the benchmark range, for any specific parameter at any specific outfall on four
occasions, the permittee shall notify the DWQ Raleigh Regional Office Supervisor in writing within
30 days of receipt of the fourth analytical results. DWQ may, but is not limited to:
• Require that the permittee revise, increase, or decrease the monitoring frequency for the
remainder of the permit;
• Require the permittee to install structural stormwater controls;
• Require the pennittee to implement other stormwater control measures;
• Require the permittee implement site modifications to qualify for a No Exposure Exclusion;
or
• Require the permittee to continue Tier Three obligations through the permit renewal
process and possibly into the next permit cycle.
This site discharges stormwater upstream of a portion of the Cape Fear River that is impaired for
aquatic life because of chlorophyll a standard violations, indicating excessive nutrient loading. If a
Total Maximum Daily Load (TMDL) is approved that affects the watershed where this plant site is
located, the Division may require additional monitoring or consider routine sample results in
determining whether additional BMPs are needed to control the pollutant(s) of concern to the
maximum extent practicable.
If additional BMPs are needed to achieve the required level of control, the permittee will be required to
(1) develop a strategy for implementing appropriate BMPs, and (2) submit a timetable for
incorporation of those BMPs into the permitted Stormwater Pollution Prevention Plan.

B. (5) QUALITATIVE MONITORING REQUIRMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified in Table 3, during the analytical
monitoring event./ Qualitative monitoring is for the purpose of evaluating the effectiveness of the
Stormwater Pollution Pievention Plan (SPPP) and assessing new sources of stormwater pollution.
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall
document the suspected cause of the condition and any actions taken in response to the discovery. This
documentation will be maintained with the SPPP.
