Permit No. NCS000578
PART I INTRODUCTION
SECTION A: INDIVIDUAL PERMIT COVERAGE
During the period beginning on the effective date of the permit and lasting until expiration, the
permittee is authorized to discharge stormwater associated with industrial activity. Such
discharges shall be controlled, limited and monitored as specified in this permit.
If industrial materials and activities are not exposed to precipitation or runoff as described in 40
CFR § 122.26(g), the facility may qualify for a No Exposure Exclusion from NPDES stormwater
discharge permit requirements. Any owner or operator wishing to obtain a No Exposure
Exclusion must submit a No Exposure Certification Notice of Intent (NOI) form to the Division;
must receive approval by the Division; must maintain no exposure conditions unless authorized
to discharge under a valid NPDES stormwater permit; and must recertify the No Exposure
Exclusion annually.
SECTION B: PERMITTED ACTIVITIES
Until this permit expires or is modified or revoked, the permittee is authorized to discharge
stormwater to the surface waters of North Carolina or separate storm sewer system that has been
adequately treated and managed in accordance with the terms and conditions of this permit. All
stormwater discharges shall be in accordance with the conditions of this permit.
Any other point source discharge to surface waters of the state is prohibited unless it is an
allowable non-stormwater discharge or is covered by another permit, authorization, or approval.
The stormwater discharges allowed by this permit shall not cause or contribute to violations of
Water Quality Standards.
This permit does not relieve the permittee from responsibility for compliance with any other
applicable federal, state, or local law, rule, standard, ordinance, order, judgment, or decree.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop and implement a Stormwater Pollution Prevention Plan (SPPP).
The SPPP shall be maintained on site unless exempted from this requirement by the Division.
The SPPP is public information in accordance with Part III, Standard Conditions, Section E,
paragraph 3 of this permit. The SPPP should also specifically and separately address
deconstruction, demolition, coal, and/or coal ash hauling or disposal activities. The SPPP shall
include, at a minimum, the following items:
1. Site Overview. The Site Overview shall provide a description of the physical facility and the
potential pollutant sources that may be expected to contribute to contamination of stormwater
discharges. The Site Overview shall contain the following:
(a) 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; the name of the receiving waters to which the stormwater outfalls discharge, or 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 points of
stormwater discharge associated with industrial activity. The general location map (or
alternatively the site map) shall identify whether any receiving waters are impaired (on
the state's 303(d) list of impaired waters) or if the site is located in a watershed for
which a TMDL has been established, and what the parameters of concern are.
(b) A narrative description of storage practices, loading and unloading activities, outdoor
process areas, dust or particulate generating or control processes, and waste disposal
practices. A narrative description of the potential pollutants that could be expected to
be present in the stormwater discharge from each outfall. The narrative should also
reference deconstruction, demolition, coal, and/or coal ash hauling or disposal activities
where applicable.
(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary; the
stormwater discharge outfalls; all on-site and adjacent surface waters and wetlands;
industrial activity areas (including storage of materials, disposal areas, process areas,
loading and unloading areas, and haul roads); site topography and finished grade; all
drainage features and structures; drainage area boundaries and total contributing area for
each outfall; direction of flow in each drainage area; industrial activities occurring in
each drainage area; buildings; stormwater Best Management Practices (BMPs); and
impervious surfaces. The site map must indicate the percentage of each drainage area
that is impervious, and the site map must include a graphic scale indication and north
arrow.
(d) A list of significant spills or leaks of pollutants during the previous three (3) years and
any corrective actions taken to mitigate spill impacts.
Part II Page 1 of 16

(e) Certification that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges. The permittee shall submit the first certification no later than
90 days after the effective date of this permit to the Stormwater Permitting Program
Central Office and shall re -certify annually that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. For any non-stormwater
discharge identified, the permittee shall indicate how that discharge is permitted or
otherwise authorized. The certification statement will be signed in accordance with the
requirements found in Part III, Standard Conditions, Section B, Paragraph 3.
2. Stormwater Management Strategy. The Stormwater Management Strategy shall contain a
narrative description of the materials management practices employed which control or
minimize the stormwater exposure of significant materials, including structural and
nonstructural measures. This strategy should also address deconstruction, demolition, coal,
and/or coal ash hauling or disposal activities where applicable. The Stormwater
Management Strategy, at a minimum, shall incorporate the following:
(a) Feasibility Study. A review of 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 rainfall and run-on flows. Wherever practical, the permittee
shall prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is not
practical, this review shall document the feasibility of diverting the stormwater run-on
away from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section 313 of
Title III of the Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals; and storage in any amount of hazardous substances, in order to prevent leaks
and spills from contaminating stormwater runoff. A table or summary of all such tanks
and stored materials and their associated secondary containment areas shall be
maintained. If the secondary containment devices are connected to stormwater
conveyance systems, the connection shall be controlled by manually activated valves or
other similar devices (which shall be secured closed with a locking mechanism). Any
stormwater that accumulates in the containment area shall be observed for color, foam,
outfall staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be uncontaminated by
any material. 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 (5) years. For facilities subject to a federal oil Spill Prevention,
Control, and Countermeasure Plan (SPCC), any portion of the SPCC Plan fully compliant
with the requirements of this permit may be used to demonstrate compliance with this
permit.
In addition to secondary containment for tankage, the permittee shall provide drip pans or
other similar protection measures for truck or rail car liquid loading and unloading
stations.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) shall be provided. The installation and implementation of BMPs shall
Part II Page 2 of 16

be based on the assessment of the potential for sources to contribute significant quantities
of pollutants to stormwater discharges and on 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 should also address deconstruction, demolition, coal, and/or coal ash hauling or
disposal activities where applicable. The permittee shall refer to the BMPs described in
EPA's Multi -Sector Permit (MSGP) and Industrial Stormwater Fact Sheet for Steam
Electric Power Generating Facilities (EPA -833-F-06-030) for guidance on BMPs that
may be appropriate for this site. The BMP Summary shall be reviewed and updated
annually.
3. Spill Prevention and Response Procedures. The Spill Prevention and Response
Procedures (SPRP) shall incorporate an assessment of potential pollutant sources based on a
materials inventory of the facility. Facility personnel 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 increased 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 and implemented. The
program shall address all stormwater control systems (if applicable), 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
where not already addressed under another element of the SPPP. Inspection of material
handling areas and regular cleaning schedules of these areas shall be incorporated into the
program. Compliance with the established schedules for inspections, maintenance, and
housekeeping shall be recorded and maintained in the SPPP. The program should also
address deconstruction, demolition, coal, and/or coal ash hauling or disposal activities where
applicable. The Good Housekeeping Program shall also include, but not be limited to, BMPs
to accomplish the following:
(a) Minimize contamination of stormwater runoff from oil-bearing equipment in
switchyard areas;
(b) Minimize contamination of stormwater runoff from delivery vehicles and rail cars
arriving and departing the plant site;
(c) Inspect all residue -hauling vehicles for proper covering over the load, adequate
gate -sealing, and overall integrity of the container body. Repair vehicles as
necessary; and
Part II Page 3 of 16

(d) Reduce or control the tracking of ash and residue from ash loading and storage
areas;
5. Facility Inspections. Inspections of the facility (including tanks, pipes, and equipment) 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 at the outfalls required in Part II B, and C of this permit.
6. 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. The facility personnel responsible for
implementing the training shall be identified, and their annual training shall be documented
either by the signature of each employee trained or by a printout of the electronic record of
the training.
7. Responsible Party. The SPPP shall identify a specific position or positions responsible for
the overall coordination, development, implementation, and revision of the SPPP.
Responsibilities for all components of the SPPP shall be documented and position
assignments provided.
8. SPPP Amendment and Annual Update. The permittee shall amend the SPPP whenever
there is a change in design, construction, operation, site drainage, maintenance, or
configuration of the physical features which may have a significant effect on the potential for
the discharge of pollutants to surface waters. All aspects of the SPPP shall be reviewed
and updated on an annual basis. The annual update shall include:
(a) an updated list of significant spills or leaks of pollutants for the previous three (3)
years, or the notation that no spills have occurred (element of the Site Overview);
(b) a written re -certification that the stormwater outfalls have been evaluated for the
presence of non-stormwater discharges (element of the Site Overview);
(c) a documented re-evaluation of the effectiveness of the on-site stormwater BMPs
(BMP Summary element of the Stormwater Management Strategy).
(d) a review and comparison of sample analytical data to benchmark values (if
applicable) over the past year, including a discussion about Tiered Response
status. The permittee shall use the Division's Annual Summary Data Monitoring
Report (DMR) form, available from the Stormwater Permitting Program's website
(See `Monitoring Forms' here: https:,[/deq.nc.gov/about/divisions/energy-
mineral-land- resources /energy-mineral-land-permits/stormwater-
permits/npdes -industrial -sw)..
If the Director notifies the permittee that the SPPP does not meet one or more of the
minimum requirements of the permit, the permittee shall have 30 days to respond. Within 30
days of such notice, the permittee shall submit a time schedule to the Director for modifying
the SPPP to meet minimum requirements. The permittee shall provide certification in
Part II Page 4 of 16

writing (in accordance with Part III, Standard Conditions, Section B, Paragraph 3) to the
Director that the changes have been made.
9. SPPP Implementation. The permittee shall implement the Stormwater Pollution Prevention
Plan and all appropriate BMPs consistent with the provisions of this permit, in order to
control contaminants entering surface waters via stormwater. Implementation of the SPPP
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 (5)
years and made available to the Director or the Director's authorized representative
immediately upon request.
Part II Page 5 of 16

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Tables 1 & 2.
All analytical monitoring shall be performed during a measurable storm event at the specified
stormwater discharge outfalls (SDOs) that discharge stormwater associated with industrial
activity (See Definitions).
A measurable storm event is a storm event that results in an actual discharge from the permitted site
outfall. The previous measurable storm event must have been at least 72 hours prior. The 72 -hour
storm interval does not apply if the permittee is able to document that a shorter interval is
representative for local storm events during the sampling period, and the permittee obtains approval
from the local DEMLR Regional Engineer. See Definitions.
The following parameters shall be monitored during a measurable storm event discharging from
the switchyards, parking lots, Service Building area, oil trap tanks, Main Fuel Oil
Storage/Unloading area and storage area designated as Outfalls SW001, SW002, SW003,
SW048, SW0565, SW078 and SW079 discharging to Yadkin River.

1 Measurement Frequency: Twice per year (unless other provisions of this permit prompt monthly
sampling) during a measurable storm event, until either another permit is issued for this facility or until
this permit is revoked or rescinded. A minimum of 60 days must separate semi-annual sample dates,
unless more frequent monitoring has been instituted (e.g., under a Tier Two response). If the facility is
monitoring monthly because of Tier Two or Three response actions under the previous permit, the facility
shall continue a monthly monitoring and reporting schedule in Tier Two or Tier Three status until
relieved by the provisions of this permit or the Division. Monitoring for PCBs may be discontinued
after the first year if results are below detection.
Part II Page 6 of 16

2 Grab samples shall be collected within the first 30 minutes of discharge. When physical separation between
outfalls prevents collecting all samples within the first 30 minutes, sampling shall begin within the first 30
minutes, and shall continue until completed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) specified above
unless representative outfall status (ROS) has been granted. The permittee may petition the Director for
ROS using DEMLR's ROS Request Form. DEMLR may grant ROS if stormwater discharges from a single
outfall are representative of discharges from multiple outfalls. Approved ROS will reduce the number of
outfalls where the analytical sampling requirements apply and will be documented in a letter to the
permittee. A copy of the Division's letter granting ROS shall be kept on site.
4 For each sampled measurable storm event, the total precipitation must be recorded. An on-site rain gauge
is required. Where isolated sites are unmanned for extended periods of time, a local rain gauge reading
may be substituted for an on-site reading.
5 Outfall sample location for SWO56 may be partially or fully submerged. An alternate sample location in this
case is at the upstream manway in the concrete diversion structure.
The following parameters shall be monitored during a measurable storm event from the
discharges mostly from roadway and rail lines, designated as Outfalls SW073, SW075,
and SW077 and discharging to Yadkin River.

Other Outfalls
The outfalls for Powerhouse Roof Drains (Outfalls SW005, SW007, SW011, SW015,
SW016, SW023, SW025, SW027, SW032, SW034, SW035, SW038, SW039, SW058, SW065,
Part II Page 7 of 16

SW066, SW067, SW069, SW070, SW071, and SW072) are all comprised of various sections
of the Powerhouse roof and all except for Outfall SW005 are inaccessible. These outfalls
are not part of any industrial activity and thus not subject to stormwater permitting. The
outfalls are to be eliminated during upcoming demolition of the Powerhouse building.
There are also two outfalls (SW080- 12"HDPE pipe and SW081-12" steel pipe), within 10
feet of outfalls SW056 and SW077, that no flow has been observed and could be out of
service. The timeline for final abandonment of these two outflows is unknown at this time.
Should the permittee identify or create any new stormwater outfalls; remove any stormwater
outfalls identified in this permit; or alter any drainage areas that change the potential
pollutants in runoff discharged through corresponding outfalls, the permittee will submit a
request to NC DEMLR to modify this permit. For any newly discovered pipes or outfalls, the
permittee must evaluate the structure and provide a report of the status and planned actions to
NC DEQ within 14 days. The permittee must either (1) request modification of this permit and
modify the SPPP accordingly, or (2) eliminate potential discharges by removal, plugging, or
combination of both.
The permittee shall complete the analytical samplings in accordance with the schedule specified
in Table 3, unless adverse weather conditions prevent sample collection (see Adverse Weather in
Definitions). Similarly, sampling is not required outside of the facility's normal operating
hours. A minimum of 60 days must separate Period 1 and Period 2 sample dates, unless
monthly monitoring has been instituted under a "Tier Two" response. Inability to sample
because of adverse weather conditions must be documented in the SPPP and recorded on the
DMR. The permittee must report the results from each sample taken within the monitoring
period (see Part III, Section E). However, for purposes of benchmark comparison and Tiered
response actions, the permittee shall use the analytical results from the first sample with valid
results within the monitoring period.

Footnotes:
1 Maintain semi-annual (quarterly) monitoring until either another permit is issued for this facility or until
this permit is revoked or rescinded. The permittee must submit an application for renewal of coverage
before the submittal deadline (180 days before expiration) to be considered for renewed coverage under the
permit. The permittee must continue analytical monitoring throughout the permit renewal process, even if
a renewal permit is not issued until after expiration of this permit.
2 If no discharge occurs during the sampling period, the permittee must submit a monitoring report indicating
"No Flow" or "No Discharge" within 30 days of the end of the sampling period.
3 Monitoring periods remain constant throughout the five-year term of the permit. Monitoring in Year
1 begins during Period 2 on August 1, 2018, and Year 5 - Period 2 ends on July 31, 2023.
4 Refer to Table 5 if transporting coal or ash and monitoring is quarterly.
Part II Page 8 of 16

Failure to monitor semi-annually (quarterly) per permit terms may result in the Division
requiring monthly monitoring for all parameters for a specified time period. "No discharge"
from an outfall during a monitoring period does not constitute failure to monitor, as long as it is
properly recorded and reported.
The permittee shall compare monitoring results to the benchmark values in Table 4. Exceedances of
benchmark values require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered
program. See below the descriptions of Tier One, Tier Two, and Tier Three response actions
below. In the event that the Division releases the permittee from continued monthly monitoring and
reporting under Tier Two or Tier Three, the Division's release letter may remain in effect through
subsequent reissuance of this permit, unless the release letter provides for other conditions or
duration.

Footnotes:
1 Hardness- dependent. Benchmark based on translation of dissolved value into total recoverable with an
assumed hardness of 25 mg/1 and a total suspended solids (TSS) concentration of 10 mg/1.
2 Values above the North Carolina water quality standard for mercury (12 ng/1) should be noted on the DMR
but do not trigger Tier responses. Concentrations infield blanks or method blanks associated with the
sample may be subtracted from the results for that sample, as long as all documentation of the adjustment
is provided with the DMR.
3 If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation
pH levels are lower, then the lower threshold of this benchmark range is the pH of the precipitation (within
instrument accuracy) instead of 6 S.U. Readings from an on-site or local rain gauge (or local precipitation
data) must be documented to demonstrate background concentrations were below the benchmark pH range
of 6- 9.
The benchmark values in Table 4 are not permit limits but should be used as guidelines for
implementation of the permittee's SPPP. An exceedance of a stormwater benchmark value is not
a permit violation; however, failure to respond to the exceedance as outlined in this permit is a
violation of permit conditions.
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 exceedance.
3. Identify potential, and select the specific feasible: source controls, operational controls, or physical
improvements to reduce concentrations of the parameters of concern, and/or to bring concentrations
within the benchmark range.
4. Implement the selected feasible actions within two months of the inspection.
5. Record each instance of a Tier One response in the SPPP. Include the date and value of the benchmark
exceedance, the inspection date, the personnel conducting the inspection, the selected actions, and the date
the selected actions were implemented.
6. Immediately institute monthly monitoring and reporting for all parameters. The permittee shall conduct
monthly monitoring at every outfall where a sampling result exceeded the benchmark value. Monthly
(analytical and qualitative) monitoring shall continue until three consecutive sample results are below the
benchmark values or within benchmark range.
7. Note: Benchmark exceedances for a different parameter separately trigger a tiered response.
Part II Page 10 of 16

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. Continue monthly monitoring and reporting for all parameters. Conduct monthly monitoring at every
outfall where a specific 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 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. Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances, contact the
DEMLR Regional Engineer as provided below in Tier Three. The Regional Engineer may direct the
response actions on the part of the permittee as provided in Tier Three, including reduced or additional
sampling parameters or frequency.
5. If pursuing this option, the permittee may propose an alternative monitoring plan for approval by the
Regional Engineer.
6. Maintain a record of the Tier Two response in the SPPP.
7. Continue Tier Two response obligations throughout the permit renewal process.
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 DEMLR Regional Engineer in writing within 30 days of receipt of the fourth analytical results;
Then: The Division may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring and reporting frequency for some
or all of the parameters herein;
• require sampling of additional or substitute parameters;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize impacts on
receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion;
• require the permittee to continue Tier Three obligations through the permit renewal process.
If a Total Maximum Daily Load (TMDL) is developed and approved for Yadkin River, or if this
body of water becomes impaired, the permittee may be required to monitor for the pollutant(s) of
concern in the future and submit results to the Division. The Division will consider the
monitoring 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 Stormwater Pollution Prevention Plan.

SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and identify new potential sources of stormwater pollution. Qualitative
monitoring of stormwater outfalls must be performed during a measurable storm event.
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status. Qualitative monitoring shall be performed quarterly as specified in
Table 4, and during required analytical monitoring events (unless the permittee is required to
perform further qualitative monitoring per the Qualitative Monitoring Response, below).
Inability to monitor because of adverse weather conditions must be documented in the SPPP and
recorded on the Qualitative Monitoring Report form (see Adverse Weather in Definitions). Only
SDOs discharging stormwater associated with industrial activity must be monitored (See
Definitions).
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.

Footnotes:
1 Monitoring Frequency: Four times per year during a measurable storm event unless other provisions of this
permit prompt monthly monitoring. See Table 5 for schedule of monitoring periods through the end of this
permitting cycle. The permittee must continue qualitative monitoring throughout the permit renewal process
until a new permit is issued.
2 Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall (SDO)
regardless of representative outfall status.

Footnotes:
1 Maintain quarterly monitoring until either another permit is issued for this facility or until this permit is
revoked or rescinded. The permittee must continue qualitative monitoring throughout the permit renewal
process, even if a renewal permit is not issued until after expiration of this permit.
2 If no discharge occurs during the sampling period, the permittee must complete a monitoring report
indicating "No Flow" or "No Discharge" within 30 days of the end of the sampling period.
3 Monitoring periods remain constant throughout the five-year term of the permit. Monitoring in Year
1 begins during Period 3 on August 1, 2018, and Year 5 - Period 3 ends on July 31, 2023.
Failure to monitor quarterly per permit terms may result in the Division requiring monthly
monitoring for all parameters for a specified time period. "No discharge" from an outfall during
a monitoring period does not constitute failure to monitor, as long as it is properly recorded.
NPDES Wastewater Permit NC0004774 requires the facility to conduct fish tissue
monitoring once during that permit term for arsenic (As), selenium (Se), and mercury (Hg)
in accordance with a Sampling Plan approved by the Division of Water Resources. The
permittee shall submit a copy of fish tissue monitoring results to the DEMLR Stormwater
Permitting Program (Central Office) within 30 days of receiving results and indicate the
location of sampling in relation to stormwater discharge outfalls. This reporting timeframe
differs from the NPDES Wastewater permit, which directs that fish tissue analysis results be
submitted with the wastewater discharge permit renewal application.
If the permittee's qualitative monitoring indicates that existing stormwater BMPs are ineffective,
or that significant stormwater contamination is present, the permittee shall investigate potential
causes, evaluate the feasibility of corrective actions, and implement those corrective actions
within 30 days, per the Qualitative Monitoring Response, below. A written record of the
permittee's investigation, evaluation, and response actions shall be kept in the Stormwater
Pollution Prevention Plan.
Part II Page 13 of 16

Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, identifying new potential
sources of stormwater pollution, and prompting the permittee's response to pollution. If the permittee
repeatedly fails to respond effectively to correct problems identified by qualitative monitoring, or if the
discharge causes or contributes to a water quality standard violation, the Division may but is not limited
to:
• require that the permittee revise, increase, or decrease the monitoring frequency for some or all
parameters (analytical or qualitative)
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize impacts
on receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion.
Part II Page 14 of 16

SECTION D: SPECIAL CONDITIONS
A (1.) ELECTRONIC REPORTING OF MONITORING REPORTS [G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports. The final NPDES Electronic Reporting Rule was adopted and became effective
on December 21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part III
of this permit (Standard Conditions for NPDES Permits):
• Section B. (3.) Signatory Requirements
• Section D. (6.) Records Retention
• Section E. (1.) Discharge Monitoring Reports
• Section E. (2.) Submitting Reports
1. Reporting Requirements [Supplements Section E. (1.) and Supersedes Section E. (2.)]
Effective December 21, 2016 or when the agency's electronic reporting system is able to
accept NPDES stormwater permit monitoring data, the permittee shall report discharge
monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report
(eDMR) internet application. NC DEMLR will notify permittees when eDMR is ready to
accept stormwater monitoring data.
Monitoring results obtained during the previous month(s) shall be summarized for each
month and submitted electronically using eDMR. The eDMR system allows permitted
facilities to enter monitoring data and submit DMRs electronically using the internet. Until
such time that the state's eDMR application is compliant with EPA's Cross -Media Electronic
Reporting Regulation (CROMERR), permittees will be required to submit all discharge
monitoring data to the state electronically using eDMR and will be required to complete the
eDMR submission by printing, signing, and submitting one signed original and a copy of the
computer printed eDMR to the following address:
NC DENR / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting
requirements may be granted and discharge monitoring data may be submitted on paper
DMR forms or alternative forms approved by the Director. Duplicate signed copies shall be
submitted to the mailing address above. See "How to Request a Waiver from Electronic
Reporting" section below.
Regardless of the submission method, the first DMR is due no later than 30 days from the
date the facility receives the sampling results from the laboratory.
Part II Page 15 of 16

2. 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 a 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.
Information on eDMR and the application for a temporary electronic reporting waiver are
found on the following web page: http://deq.nc.gov/about/divisions/water-resources/edmr
3. Signatory Requirements [Supplements Section B. (3.) (b) and Supersedes Section B. (3.)
All eDMRs submitted to the permit issuing authority shall be signed by a person described in
Part III, Section B. (3)(a) or by a duly authorized representative of that person as described
in Part III, Section B. (3)(b). A person, and not a position, must be delegated signatory
authority for eDMR reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR
user account and login credentials to access the eDMR system. For more information on
North Carolina's eDMR system, registering for eDMR and obtaining an eDMR user account,

Part III Page 5 of 10

SECTION C: OPERATION AND MAINTENANCE OF POLLUTION CONTROLS
Proper Operation and Maintenance
The permittee shall at all times properly operate and maintain all facilities and systems of treatment and
control (and related appurtenances) which are installed or used by the permittee to achieve compliance with
the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls
and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary
facilities or similar systems which are installed by a permittee only when the operation is necessary to
achieve compliance with the conditions of this permit [40 CFR 122.41(e)].
Need to Halt or Reduce Not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt
or reduce the permitted activity in order to maintain compliance with the condition of this permit [40 CFR
122.41(c)].
Bypassing of Stormwater Control Facilities
Bypass is prohibited and the Director may take enforcement action against a permittee for bypass unless:
a. Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; and
b. There were no feasible alternatives to the bypass, such as the use of auxiliary control facilities,
retention of stormwater, or maintenance during normal periods of equipment downtime or dry weather.
This condition is not satisfied if adequate backup controls should have been installed in the exercise of
reasonable engineering judgment to prevent a bypass which occurred during normal periods of
equipment downtime or preventive maintenance; and
c. The permittee submitted notices as required under, Part III, Section E of this permit.
If the Director determines that it will meet the three conditions listed above, the Director may approve an
anticipated bypass after considering its adverse effects.
Part III Page 6 of 10

SECTION D: MONITORING AND RECORDS
Representative Sampling
Samples collected and measurements taken, as required herein, shall be characteristic of the volume and
nature of the permitted discharge. Analytical sampling shall be performed during a measurable storm
event. Samples shall be taken on a day and time that is characteristic of the discharge. All samples shall be
taken before the discharge joins or is diluted by any other waste stream, body of water, or substance.
Monitoring points as specified in this permit shall not be changed without notification to and approval of
the Permit Issuing Authority [40 CFR 122.410)].
Recording Results
For each measurement or sample taken pursuant to the requirements of this permit, the permittee shall
record the following information [40 CFR 122.41]:
a. The date, exact place, and time of sampling or measurements;
b. The individual(s) who performed the sampling or measurements;
c. The date(s) analyses were performed;
d. The individual(s) who performed the analyses;
e. The analytical techniques or methods used; and
f. The results of such analyses.
Flow Measurements
Where required, appropriate flow measurement devices and methods consistent with accepted scientific
practices shall be selected and used to ensure the accuracy and reliability of measurements of the volume of
monitored discharges.
Test Procedures
Test procedures for the analysis of pollutants shall conform to the EMC regulations published pursuant to
NCGS 143-215.63 et. seq, the Water and Air Quality Reporting Acts, and to regulations published pursuant
to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act, as Amended, and Regulation
40 CFR 136.
To meet the intent of the monitoring required by this permit, all test procedures must produce minimum
detection and reporting levels and all data generated must be reported down to the minimum detection or
lower reporting level of the procedure. If no approved methods are determined capable of achieving
minimum detection and reporting levels below permit discharge requirements, then the most sensitive
(method with the lowest possible detection and reporting level) approved method must be used.
Representative Outfall
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.
Records Retention
Visual monitoring shall be documented and records maintained at the facility along with the Stormwater
Pollution Prevention Plan. Copies of analytical monitoring results shall also be maintained on-site. The
permittee shall retain records of all monitoring information, including
o all calibration and maintenance records,
o all original strip chart recordings for continuous monitoring instrumentation,
o copies of all reports required by this permit, including Discharge Monitoring Reports (DMRs),
o copies of all data used to complete the application for this permit
