1.0 GENERAL INFORMATION
November 24, 2014
This Stormwater Pollution Prevention Plan (SWPP Plan) is required by Part II, Section A of NPDES
Permit NCS000348 to discharge stormwater from the Southport plant. The permit may be found in
Appendix G. This plan identifies potential pollutant sources at the Southport plant that could cause
surface water or ground water pollution. These sources include production operations and the handling
and storage of significant materials at the plant. This plan contains the elements required by Part II
Section A of the permit for minimizing stormwater pollution, and includes a summary of qualitative
and quantitative monitoring requirements applicable to each stormwater outfall.
The plant is located on Powerhouse Road, in Southport, North Carolina. Figure 1-1 is a
general location map showing the Southport plant in relation to transportation routes and
surface waters. All of the plant's stormwater outfalls discharge into an unnamed, intermittent
stream which originates just south of the leased property, flows west, then turns north,
discharging from a culvert beneath the main rail line. This stream, which is the surface water
feature near the plant property and is within 100-feet of the leased property boundary, then
flows to the north, ultimately joining the Duke Energy Cooling Water Canal at a point north of
the plant. The plant's wastewater basin discharge is pumped through a pipeline which also
discharges into the Duke Energy Cooling Water Canal. Figure 1-1 also indicates the latitude
and longitude of each of the plant's stormwater outfalls.
Figure 1-2 is a site layout diagram of the Southport plant. The diagram indicates the leased
property boundary, the stormwater discharge outfalls, on -site and adjacent surface waters,
industrial activity areas, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each drainage area,
buildings, existing BMPs, and impervious surfaces. The percentage of each drainage area that
is impervious is shown in the table following Figure 1-2. Site topography is generally level
except for storage piles of coal, tire -derived fuel (TDF), wood chips, soil, and ash storage.
Figure 1-2 also includes current information about the receiving stream's status on the state's
303(d) list of impaired waters, whether the receiving stream is located in a watershed for
which a TMDL has been established, and what the parameters of concern are.

2.0 SITE PLAN
There are seven drainage areas and six stormwater outfalls at the Southport plant site. These
areas, delineated based on visual observations, review of available drawings, and discussions
with plant personnel, are shown in Figure 1-2.
2.1 General Location Map
The general location map for the Southport plant is presented in Figure 1-1.
2.2 Narrative Description of Potential Pollutant Sources
Drainage Area 1
Description of Area: Drainage Area 1 (DAI) includes
part of the power block portion of the Southport Plant.
Plant facilities located in DAI include: the Boiler and
Turbine Buildings with Conveyors and Conveyor
Towers, Baghouses and Exhaust Stacks, an Ash Silo and
ash unloading station, a Limestone Silo and limestone
unloading, Condensate Tank, and paved roads. The total
surface area of )A I is ±3.8 acres, of which ±2.0 acres are
impervious surfaces (i.e., buildings and roads). The area
of the two Transformer Yards are excluded from DAI, because stormwater from these yards
drains to the Oil Trap Pit and is then pumped to the Wastewater Basin.
Stormwater Facilities: The land in DAI drains to catch basins located along the road that
encircles the power block. The catch basins are connected via a buried storm sewer that exits
the site at Stormwater Outfall No. 1 (001) and enters a drainage canal. The drainage canal
discharges through Stormwater Outfall No. 5 (005) at the northwest corner of the leased
property, then flows through a culvert beneath the main rail line, continues north for about 0.5-
miles, and then discharges into the Duke Energy Cooling Water Canal.
Potential Pollution Source(s): The potential sources of storm water pollution in DAI are
discussed below:
1. Turbine Building and Boiler Building — Both of these buildings house equipment and
vessels (in the Oil Storage Room) which contain lubricating and hydraulic oils needed for
the steam turbines. This equipment has either conforming secondary containment or
diversion systems (to the Oil Trap Pit — which is in DA3) that provide conforming
secondary containment. Bulk transfer of oil products to the Oil Storage Room occurs via
truck inside the Building and any leaks/spills from the truck would flow to the floor drains
and then to the Wastewater Basin for treatment. The Building is fully enclosed and does
not present any potential for storm water pollution.
5

Southport Plant SWPP Plan
November 24, 2014
2. Conveyors and Conveyor Towers — Coal, wood and TDF occasionally falls from the
covered conveyors onto the ground beneath. The quantity of material that falls in this
manner is very small (on the order of <100 lbs/year), and the ground beneath the conveyor
is regularly policed to keep the area clean. These pieces have a small surface area to
volume ratio and therefore, a low potential to leach pollutants. Therefore, the potential
from storm water pollution from the Conveyors and Conveyor Towers is low.
3. Ash Silo (1) — An ash silo is located near the northwest corner of the Boiler Building.
Stormwater from the immediate vicinity of the ash silo is routed to the stormwater system.
The ash silo is equipped with an enclosed ash slurry system which makes a wet slurry
from the ash which is then loaded into trucks to minimize the generation of fugitive ash.
As such, the ash silo is a moderate risk as a source of stormwater pollution.
4. Limestone Silo (1) — A limestone silo is located near the ash silo. This is an enclosed
system which receives and delivers limestone via closed pneumatic systems. Limestone
can be pneumatically injected into the boilers via a closed piping system. Maintenance of
these systems will first involve system evacuation prior to opening to avoid releasing
limestone to grade. As such, the limestone silo is a moderate risk as a source of
stormwater pollution.
5. Condensate Tank — This tank contains demineralized water. As such, the potential for
storm water pollution from this tank is low.
6. Paved Roads — Currently, these roads only experience light traffic. As such, there is low
potential for storm water pollution from these sources.
Drainage Area 2
Description of Area: Drainage Area 2 (DA2) is in the
north -central portion of the Plant Site and has a drainage
area of ±5.4 acres. Plant facilities in DA2 include the
Coal Pile and Coal Storage Area, Wood Storage pad and
storage areas, Conveyors, Radial Stackers, TDF storage
area, the Wastewater Basin and Wastewater Treatment W
Building, and the Maintenance/Warehouse Building.'`
Additionally, both Transformer Yards are part of this
area, because stormwater from these yards flows to the Oil Trap Pit, and is then pumped to the
Wastewater Basin.
Stormwater Facilities: Except for the Transformer Yards, drainage within DA2 is routed to
the `V-ditch' the surrounds the Coal Pile and Coal Storage Area. Both the Transformer Yards
(via the Oil Trap Pit) and the `V-ditch' discharge stormwater into the Wastewater Basin for
treatment via pH adjustment and sedimentation. The Wastewater Basin discharges through
Wastewater Outfall 001 under NPDES Industrial Permit No. NC0065099.
6

Southport Plant SWPP Plan
November 24, 2014
Potential Pollution Source(s): Storm water pollution sources in DA2 include handling,
conveying, and storage of coal, wood chips, and tire derived fuel within the drainage area, and
any stormwater that contacts oil in the Oil Trap Pit. There is no potential for storm water
pollution from DA2 in the plant's stormwater-only outfalls, because all storm water runoff is
controlled and treated as an industrial wastewater before being discharged through
Wastewater Outfall 001.
Drainage Area 3
Description of Area: Drainage Area 3 (DA3) is located
in the eastern portion of the plant site and has a drainage
area of ±9.7 acres. Plant facilities in DA3 include portions
of the Cooling Towers, the Cooling Tower Chemical
Storage Areas, the Switch Yard, the Oil Trap Pit, the
Truck Dumpers, the Rail Car Unloading Area, the
Railroad Spur, and coal and wood unloading conveyors.
A sub -basin within DA3 drains to a sand filter. The
location of this filter is shown in Figure 1-2. The sand filter is designed to remove 85% of the
Total Suspended Solids from the sub -basin's stormwater before it is discharged to the northern
part of DA3. Excess stormwater collected in DA3 is discharged through
Stormwater Outfall No. 3 (003).
Stormwater Facilities: Stormwater runoff from the southern part of DA3 shown in the
sketch above, including the Truck Dumpers areas, either sinks into the ground, flows into the
sand filter, or, in the case of a very large storm, may flow along the railroad spurs in a
northwesterly direction and be discharged through Stormwater Outfall No. 3 (003).
Stormwater from the northern part of DA3 includes any stormwater that is discharged from
the sand filter, and either sinks into the ground or flows in a northwesterly direction and may
be discharged through Stormwater Outfall No. 3 (003).
Potential Pollution Source(s): The potential storm water pollution sources in DA3 are
discussed below:
1. Cooling Towers — Precipitation that falls directly on/into the cooling towers becomes an
industrial wastewater and does not enter the storm water system. Drift from the cooling
towers (flow magnitude of 5-gpm when the towers are operating) does occur and a portion
of the drift settles on the ground in the vicinity of the towers. The drift contains the
minerals naturally present in the cooling water make-up sources (i.e., groundwater and/or
potable municipal supply), and none of the cooling tower chemicals contain any of the 126
priority pollutants. Therefore, the potential for storm water pollution from the cooling
towers is low.
7

Southport Plant SWPP Plan
November 24, 2014
2. Cooling Tower Chemical Storage Areas — The chemical storage areas associated with the
cooling towers are equipped with conforming secondary containment with a dike valve
that is normally maintained in a closed and locked position. Rainwater that accumulates in
the containment areas is inspected as required by NPDES Stormwater Permit
NCS000348, Part II.A.2.(b) before it is released to the storm water system. The bulk
transfer of cooling tower chemicals occurs from tank trucks that are positioned in a
dedicated unloading area equipped with conforming secondary containment, with a dike
valve that is maintained in a closed position during unloading operations. Therefore, the
potential for storm water pollution from the Cooling Tower Chemical Storage Area is low.
3. Rail Car Unloading Area — A diesel fuel tank and a hydraulic fluid reservoir/system are
located within conforming secondary containment equipped with a dike valve that is
normally maintained in a closed and locked position. Rainwater that accumulates in the
containment area is inspected per the requirements of NPDES Storm water Permit
NCS000348, Part II.A.2.(b) before it is released to the storm water system. The bulk
transfer of diesel fuel occurs from tank trucks that are positioned in a dedicated unloading
area within the conforming secondary containment, with a dike valve that is maintained in
a closed position during unloading operations. Therefore, the potential for storm water
pollution from the Coal Unloading Area is low.
4. Coal Conveyors — Coal occasionally falls from the covered conveyor belt onto the ground
beneath. The quantity of coal that falls in this manner is small (on the order of 100
lbs/year) and, the ground beneath the conveyor is regularly policed to keep the area clean.
The coal pieces have a small surface area to volume ratio (i.e., minimal exposed coal) and
therefore, a low potential to leach pollutants. Therefore, the potential from storm water
pollution from the Coal Conveyors is low.
5. Truck Dumpers and Wood Conveyors — Wood chips falling from the Truck Dumper or
Wood Conveyors while the chips are transferred from the Truck Dumper to the Radial
Stacker represents a stormwater pollution risk. During all but the largest storm events,
stormwater contacting these activities either sinks into the ground, or flows into the sand
filter, which is designed to remove most of the incoming Total Suspended Solids.
Therefore, the potential from storm water pollution from this activity is low. Both Truck
Dumpers have Hydraulic Oil Tanks and a 300-gal Diesel Tanks„ all located within
conforming secondary containment and equipped with a dike valve normally maintained
in a closed and locked position. Rainwater that accumulates in the containment area is
inspected per the requirements of NPDES Storm water Permit NCS000348, Part II.A.2.(b)
before it is released.
6. Railroad Spur — Coal occasionally falls from the rail cars onto the ground beneath and
adjacent to the railroad spur. The quantity of coal that falls in this manner is small (on the
magnitude of several hundred pounds per year), and the railroad spur is regularly policed
to keep the area clean. The coal pieces have a small surface area to volume ratio (i.e.,
minimal exposed coal) and therefore, a low potential to leach pollutants. Therefore, the
potential for storm water pollution from the railroad spur is low.
7. Switch Yard and Oil Trap Pit — The Switch Yard, which is not a part of the leased
property, is not a source of stormwater pollution. The Oil Trap Pit is an uncovered oil -
water separator that may collect rainfall. Any rainfall that falls directly into the Oil Trap
Pit is pumped or otherwise conveyed to the Wastewater Basin for treatment and
subsequent discharge through Wastewater Outfall 001.
8

Southport Plant SWPP Plan
November 24, 2014
Drainage Area 4
Description of Area: Drainage Area 4 (DA4) has an
area of ±0.7 acres that is bounded by the southern
half of the cooling towers and a portion of the Plant's
entrance road. Plant facilities included in DA4 are the
southern half of the two cooling towers.
Stormwater Facilities: Storm water runoff from DA4 is
either by overland flow, or a shallow drainage swale, and
collects in a drainage catch basin on the northern side of
the entrance road immediately adjacent to Stormwater Outfall No. 4 (004). Runoff enters the
catch basin, traverses a culvert under the road and exits the Plant site via Outfall No. 4 (004).
After traversing the Outfall, runoff flows through a drainage canal parallel to and outside of
the plant's southern and western boundaries. The drainage canal discharges through
Stormwater Outfall No. 5 (005) at the northwest corner of the leased property, then flows
through a culvert beneath the main rail line, continues north for about 0.5-miles, and then
discharges into the Duke Energy Cooling Water Canal.
Potential Pollution Source(s): The sole potential pollution source is from the cooling towers.
Precipitation that falls directly on/into the cooling towers becomes an industrial wastewater
and does not enter the storm water system. Drift from the cooling towers (flow magnitude of
5-gpm when the towers are operating) does occur and a portion of the drift settles on the
ground in the vicinity of the towers. The drift contains the minerals naturally present in the
cooling water make-up sources (i.e., groundwater and/or potable municipal supply), and none
of the cooling tower chemicals contain any of the 126 priority pollutants. Therefore, the
potential for storm water pollution from the cooling towers is low.
Drainage Area 5
Description of Area: Drainage Area 5 (DA5) covers
±9.8 acres that include the plant site areas adjacent to the
southern and western plant boundaries. Most of DA5 is
impervious (±8.8 acres). Plant facilities within this
area include: the Demineralizer Building, the
Neutralization Tank, the Reverse Osmosis Building, the
Drum Storage Area, Water Tanks (for raw water storage),
trash dumpsters, and a portion of the paved entrance road.
Stormwater Facilities: Storm water in DA5 leaves the site exclusively by overland flow.
Runoff flows towards the plant's boundary where it flows into a drainage canal that is parallel
to and outside of the plant's southern and western boundaries. Sheet flow drainage from
grassy areas in DA5 are directed to 2 internal discharge points by a soil levee which drain into
the drainage canal that is parallel to and outside of the plant's southern and western
boundaries. Stormwater Outfalls No. 1 (001), No. 4 (004), and No. 6 (006) discharge into this
canal, upstream of Stormwater Outfall No. 5 (005).
7

Southport Plant SWPP Plan
November 24, 2014
Flow direction in the southern portion of the canal is towards the west and in the western
portion of the canal is to the north. The drainage canal discharges through Stormwater Outfall
No. 5 (005) at the northwest corner of the leased property, then flows through a culvert
beneath the main rail line, continues north for about 0.5-miles, and then discharges into the
Duke Energy Cooling Water Canal.
Potential Pollution Source(s): The potential storm water pollution sources in DA5 are
discussed below:
1. Demineralizer Building — the Demineralizer Building houses the bulk acid and caustic
tanks (5,400-gallons each) and the acid and caustic day tanks (100-gallons each). These
tanks have conforming secondary containment and are protected from precipitation
because they are located inside an enclosed building. Doorways to the building are
protected by concrete berms that ensure that any incidental drips/spills are also provided
with containment. There is no potential for storm water pollution from the Demineralizer
Building.
2. Neutralization Tank — the Neutralization Tank is an FRP process water tank that is
surrounded by a "U-shaped" concrete swale.
3. Reverse Osmosis Building - the chemicals that are stored in tanks in the Reverse Osmosis
(RO) Building are stored within secondary containment. The floor is sloped towards a
drain that discharges into the chemical sump from the Demineralizer Building. There is
no potential for storm water pollution from the RO Building.
4. Water Tanks - used for raw water storage. There is no potential for storm water pollution
from the Water Tanks.
5. Paved roads and trash dumpsters — there is minimal potential for storm water pollution
from these sources. Paved roads have minimal impact on stormwater pollution because all
trucks are required to be covered, tarped, or enclosed, which minimizes spillage. Only
debris free of oil is placed into the trash dumpsters.
Drainage Area 6
Description of Area: Drainage Area 6 (DA6) has an
area of ±0.5 acres, and drains a small area just to the north
of the Wastewater Basin, as shown in the sketch.
Stormwater Facilities: Storm water runoff from DA6 is
either by overland flow, or a shallow drainage swale, and
flows across the northern leased property boundary
through Stormwater Outfall No. 2 (002). Then, the runoff
flows through a culvert beneath the main rail line, continues
north for about 0.5-miles, and then discharges into the Duke Energy Cooling Water Canal.
10

Southport Plant SWPP Plan
November 24, 2014
Potential Pollution Source(s): Potential pollution sources are from the storage of new and
used equipment along the security fence, and from wastewater treatment chemical totes which
are equipped with secondary containment. The stored equipment is mainly between 50 and
150 spools of wire, as well as new and used equipment. Precipitation would contact the
equipment, spools, metal wire, and/or plastic composite insulation before running off.
Therefore, the potential for storm water pollution from this source is low.
Drainage Area 7
Description of Area: Drainage Area 7 (DA7) has an
area of ±0.8 acres, and drains a small area on the east
side of the Turbine Building, as shown in the sketch.
Stormwater Facilities: Storm water runoff from DA7 is
either by overland flow, or through drop inlets and a
system of underground sewers. It flows east and
discharges into the canal that discharges through
Stormwater Outfall No. 5 (005). Then, the runoff flows through a culvert beneath the main rail
line, continues north for about 0.5-miles, and then discharges into the Duke Energy Cooling
Water Canal.

pollution sources in DA7 are discussed below:
1. Pump House — a 300-gallon Diesel Fuel Tank is located outside, between the Pump House
and the R.O. Building. The tank provides fuel for the Emergency Fire Water Pump
(powered by a diesel engine), which resides within the Pump House. The diesel tank is
located within conforming secondary containment equipped with a dike valve that is
normally maintained in a closed and locked position. Rainwater that accumulates in the
containment area is inspected per the requirements of NPDES Storm water Permit
NCS000348, Part II.A.2.(b) before it is released to the storm water system. Because the
fire pump engine is operated only during tests and emergencies, very little diesel fuel is
used, and the bulk transfer of diesel fuel into this tank occurs very infrequently. Fuel is
transferred from a tank truck using the procedures for unloading operations described in
the plant's SPCC Plan. Therefore, the potential for storm water pollution from the Pump
House is low.
2. Electric Fire Pump (EFP) Transformer — the EFP Transformer contains 125-gallons of
transformer oil and is located outside of the Pump House in a conforming secondary
containment structure. The containment structure is kept under administrative control and
accumulated rainwater is released only after inspection, per the requirements of NPDES
Storm water Permit NCS000348, Part II.A.2.(b). There is a low risk potential for storm
water pollution from the EFP Transformer.

3. Unloading Bay — the unloading bay is used to transfer chemicals stored in the
Demineralizer Building, and contains no materials that may potentially contaminate storm
water except during active transfer operations, which are performed using the procedures
for unloading operations described in the plant's SPCC Plan. This concrete pad drains to
the Demineralization sump which is then pumped to the Neutralization Tank, which can
drain to the Wastewater Basin. As such, there is a low risk potential for storm water
pollution from this Unloading Bay.
4. Gasoline and Drum Storage Area — this area is used to store a 30-gallon gasoline dispenser
or water treatment chemical drums. The area is equipped with a concrete berm and a
partial roof, and has conforming secondary containment equipped with a dike valve that is
normally maintained in a closed and locked position.
5. Conveyors and Conveyor Towers — Coal, wood and TDF occasionally falls from the
covered conveyors onto the ground beneath. The quantity of material that falls in this
manner is very small (on the order of <100 lbs/year), and the ground beneath the conveyor
is regularly policed to keep the area clean. These pieces have a small surface area to
volume ratio and therefore, a low potential to leach pollutants. Therefore, the potential
from storm water pollution from the Conveyors and Conveyor Towers is low.
6. Ash Silo (1) — An ash silo is located near Pump House near the corner of the Boiler
Building. Stormwater from the immediate vicinity of the ash silo is routed to the
stormwater system. The ash silo is equipped with an enclosed ash slurry system which
makes a wet slurry from the ash which is then loaded into trucks to minimize the
generation of fugitive ash. As such, the ash silo is a moderate risk as a source of
stormwater pollution.
7. Limestone Silo (1) — A limestone silo is located near the ash silo. This is an enclosed
system which receives and delivers limestone via closed pneumatic systems. Limestone
can be pneumatically injected into the boilers via a closed piping system. Maintenance of
these systems will first involve system evacuation prior to opening to avoid releasing
limestone to grade. As such, the limestone silo is a moderate risk as a source of
stormwater pollution.
8. Paved Roads — Currently, these roads only experience light traffic. As such, there is low
potential for storm water pollution from these sources.
Laydown Yard Areas
Many areas at the plant where extra material (mostly metal piping and wood) is stored are
called Laydown Yard Areas. The equipment and material stored in these areas are not under
cover or enclosed within a containment berm. However, the types of materials stored in these
areas are not amenable to erosion nor are they potentially significant sources of storm water
pollution.

2.4 Spill/Leak History
There have been no significant spills (i.e., spills that have exceeded their reportable quantities) that
have occurred at the facility during the 3 years prior to the date of this plan.
2.5 Non-Stormwater Discharge Certification
Plant personnel will evaluate storm water outfalls for the presence of unauthorized non -storm water
discharges, such as process wastewater, non -contact cooling water, vehicle wash water, or sanitary
wastewater. (Authorized non -storm water discharges are discussed in Section 2.5.2, below.) This
evaluation will consist of an annual visual inspection of all stormwater outfalls during periods of dry
weather. If more information is necessary to fully evaluate the potential for non -storm water
discharges, a plant schematic or sewer map will be reviewed to determine whether unauthorized non -
storm water discharges might be entering the on -site storm sewer system. The forms in Appendices
B 1 and 132 should be completed annually.
15

Southport Plant SWPP Plan
November 24, 2014
2.5.1 Procedure for Conducting a Non -Storm Water Assessment
This procedure applies to all six (6) Stormwater Outfalls (see Figure 1-2).
During times of no precipitation, observe each applicable storm water outfall on three separate
occasions — The most practical method for detecting the presence of non -storm water sources in a
storm water collection system is to observe all applicable storm water outfalls during times of no
precipitation. As guidance, "times of no precipitation" can be defined as a dry day preceded by at least
72 hours of no measurable rainfall events (<O.1 inch). The observations should be done on three (3)
separate days. As a rule, the outfall should be dry. However, drainage of a particular rain event can
continue for three days or more after the rain has stopped. In addition, infiltration of ground water into
the storm water collection system is also common. To be sure about the source of any flow during dry
weather, use of dye testing or an equivalent method may be necessary.
Record each observation of each applicable storm water outfall on Appendix B-1, and
include a notation for any non -storm water discharges identified.
2. The source of any observed non -storm water discharges must be determined and
identified Appendix 13-1. When completed, for each outfall assessed, Appendix 13-1
should have one entry for each of the three observations, for a total of three entries per
outfall.
Sign and date the certification — The certification at the bottom is required by the
Storm Water General Permit. The signature indicates that each outfall has been
evaluated for the presence of non -storm water discharges and that results indicated on
the form are accurate.
4. After making a copy, insert the completed original into the Storm Water Pollution
Prevention Plan, and send the copy to the Senior Advisor, Environmental.
Complete Appendix B2 only if an outfall discharge cannot be observed. Contact the
Senior Advisor, Environmental immediately if this situation exists.
A non -storm water assessment may not be feasible if the facility does not have access to an outfall,
manhole, or other point of access to the storm water drainage system. In such cases, Appendix B2
should be completed indicating why the certification was not feasible. Please contact the Senior
Advisor, Environmental immediately if you cannot observe an outfall. The Senior Advisor,
Environmental is responsible for making this notification.

2.5.2 Authorized Non-Stormwater Discharges (NPDES Permit Part VI.3.)
Stormwater Permit NCS000348 allows all other discharges that are authorized by a non-stormwater
NPDES permit to enter a stormwater conveyance. Stormwater Permit NCS000348 prohibits from
stormwater conveyances all non -storm water discharges, except for discharges of. uncontaminated
groundwater, foundation drains, air -conditioner condensate without added chemicals, springs,
discharges of uncontaminated potable water, waterline and fire hydrant flushings, water from footing
drains, flows from riparian habitats and wetlands, and discharges resulting from fire -fighting or fire-
fighting training.

3.0 STORMWATER MANAGEMENT PLAN
3.1 Feasibility Study
The purpose of the Feasibility Study is to determine the technical and economic feasibility of
preventing stormwater exposure at any plant facility that stores, handles, or manufactures a material
that poses a stormwater pollution risk. The Southport plant currently has diverted runoff from several
areas (e.g., coal pile, transformer yards, wood and TDF storage areas) to the Wastewater Basin for
treatment prior to discharge through the industrial NPDES outfall. The following paragraphs present
the evaluations for all Plant Drainage Areas (DAs) that have materials exposed to precipitation events:
DA1 and DA7
The areas surrounding the Ash Silos, Limestone Silos, and beneath the Conveyors and
Conveyor Towers can occasionally have ash or coal end up on the land surface. The silo
system is sealed, and the limestone is removed from the equipment prior to maintenance. The
volume of material thusly deposited is small and the potential for stormwater pollution from
these materials is low because coal and ash have low solubility in water. The very low
stormwater pollution risk from the Limestone Silos makes treatment of the stormwater
unnecessary — other than by the existing Good Housekeeping BMPs. Because the fly ash is
slurried before being loaded into trucks, there is minimal fly ash in the stormwater. Diesel
fuel loading into the tank behind the Pump House is rarely performed and, as noted in the
unloading procedures listed in the plant's SPCC Plan, fuel transfer operations are not
permitted during rainfall events. The EFP Transformer and Gasoline and Drum Storage Area
have conforming secondary containment, and drainage from the Unloading Bay drains to the
Demineralization sump which is then pumped to the Neutralization Tank, which can drain to
the Wastewater Basin. As such, there is a low risk potential for storm water pollution from this
Unloading Bay. Paved roads in DA 1 and DA7 have minimal impact on stormwater pollution
because all trucks are required to be covered, tarped, or enclosed when they are not being
loaded or unloaded, which minimizes spillage during transport.
DA2
Stormwater runoff from DA2 is routed to, and treated in the Industrial NPDES wastewater
system.
DA3
The Cooling Towers, the Cooling Tower Chemical Storage Areas, and the Oil Trap Pit have
no "uncontrolled" exposure of materials to stormwater and therefore do not present a
significant risk for stormwater pollution. Any stormwater that may be exposed to materials is
retained within containment and released only in accordance with the procedures detailed in
40 CFR 112.8(c)(3). Except during very large storms, runoff from the Truck Dumpers and
wood unloading conveyors is treated in the sand filter to remove TSS. The Truck Dumpers'
Hydraulic Oil Tanks have conforming secondary containment. Coal cars that may
temporarily sit on the rail spur do not represent a significant stormwater pollution source.
18

Southport Plant SWPP Plan November 24, 2014
Diesel fuel tanks and the hydraulic fluid reservoir in the Rail Car Unloading Area have
conforming secondary containment.
DA4
The Cooling Towers have no "uncontrolled" exposure of materials to stormwater and
therefore do not present a significant risk for stormwater pollution.
DA5
The Demineralizer Building, Neutralization Tank, Reverse Osmosis Building, and Water
Tanks have no "uncontrolled" exposure of materials to stormwater and therefore do not
present a significant risk for stormwater pollution. Paved roads in DA5 have minimal impact
on stormwater pollution because all trucks are required to be covered, tarped, or enclosed
when they are not being loaded or unloaded, which minimizes spillage during transport. Only
non -oily debris will be stored in the he trash dumpsters located in DA5.
3.2 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. Table 2-1 lists all such tanks and stored materials and
their associated secondary containment areas. 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 closed with a locking mechanism), and any
stormwater that accumulates in the containment area shall be at a minimum visually 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 the material
stored within the containment area.
3.3 BMP Summary
Table 2-1, above, provides a list of the BMPs used at the Southport plant.
Potentially exposed materials at the Southport plant include coal, wood chips, tire derived fuel (TDF),
petroleum products stored in existing ASTs, water and wastewater treatment chemicals, limestone,
and ash.
Coal for the boiler plant is stored outside in the coal pile and coal pile runoff is treated in the low
volume wastewater system prior to discharge (i.e., it is not drained to the stormwater system). Coal is
brought in by rail at the north end of the plant and unloaded through the coal chute and transported via
conveyor belt to the coal pile. The risk of coal dust entering the storm water via fugitive dust exists
and to minimize that risk, coal unloading BMPs are used and, because the drainage adjacent to the rail
bed is through vegetative buffers, the quantity of coal reaching the receiving water is minimal. Water
is sprayed onto the coal, as needed, as it is unloaded from the rail cars in one of the coal unloading
19

Southport Plant SWPP Plan November 24, 2014
BMPs. Also, coal dust from the edges of the chute where coal is deposited is swept up daily after
unloading operations. These BMPs minimize fugitive dust transport.
The risk of the petroleum products entering the storm system is low due to the use of secondary
containment that conforms to 40 CFR 112.8(c)(2) and non-structural controls (e.g., routine
inspections) to prevent spills. Used oil is stored in a 300-gallon aboveground storage tank (AST)
located at inside the Boiler Building's Oil Storage Room, with full volume secondary containment.
Diesel is stored in a 300-gallon AST outside the Pump House, in a 1,000-gallon AST located within
the Rail Car Unloading Area, and in a 300-gallon AST near Truck Dumper 2, all equipped with full
volume secondary containment. Gasoline is stored in a 30-gallon dispenser located in the Gasoline
and Drum Storage Area which is also equipped with full volume secondary containment. Small tanks
of turbine lube oil and hydraulic oil are located on the site, as well as transformers containing oil. Any
spillage from these tanks and transformers would normally be contained by full volume secondary
containment.
Chemical storage and usage is limited to the Wastewater Basin (drums and totes containing chemicals
are stored outside, equipped with full volume secondary containment), the Demineralizer Building
area, the R.O. Building area, and the Cooling Tower Chemical Storage Area. The several chemical
storage units in the Demineralizer Building are all equipped with secondary containment and, any
spills are routed to the Neutralization Tank and then the Wastewater Basin for treatment. Spill cleanup
materials are located inside the Warehouse and the R.O. Building. There is a dedicated Unloading Bay
at the Demineralizer Building. Most of the chemicals used in the R.O. Building are stored within
secondary containment or on a chemical skid on the floor in the building. The floor is sloping towards
a drain that discharges into the chemical sump from the Demineralizer Building. A temporary tank
designed to store bleach for treating well water is located within full volume containment just outside
the R.O. Building. Chemicals stored in the Cooling Tower Chemical Storage Area are equipped with
full volume secondary containment.
The risk of ash or ash residue entering the storm system is low due to the use of dikes and controls (i.e.
Dustmaster). When a truck is loaded with ash, a slurry system is used to minimize fugitive ash and
spillage. The risk of the petroleum products entering the storm system is low due to the use of
secondary containment that conforms to 40 CFR 112.8(c)(2) and non-structural controls (e.g., routine
inspections) to prevent spills.
The risk of limestone entering the storm system is low due to the use of structural and non-structural
controls (i.e. the limestone silo and its blowers and piping are sealed, and limestone is removed from
equipment prior to maintenance). Limestone is pneumatically conveyed in closed lines. Any spills of
limestone will be promptly cleaned up.
Wood chips and TDF may spill from trucks on paved or gravel roads, the truck dumpers, conveyors,
and radial stacker. The risk of these materials contaminating stormwater is low because accumulated
stormwater flows through a sand filter to remove TSS from the water before it is discharged off -site.
The sand filter is covered by a Sand Filter Operation and Maintenance Agreement which is
incorporated into State Stormwater Management Permit No. SWS 090511. That permit was issued on
20

Southport Plant SWPP Plan
November 24, 2014
7-19-2013. Trucks are covered, tarped, or enclosed when not being loaded or unloaded, and paved
roads are swept periodically. Spilled materials are promptly cleaned up.
21

Southport Plant SWPP Plan November 24, 2014
4.0 SPILL PREVENTION AND RESPONSE PLAN
Areas of the facility where potential spills can occur that may contribute pollutants to storm water
discharges and their accompanying drainage points are identified on Figure 1-2 (Site Drainage
Drawing Showing Locations of Potentially Exposed Materials) and Table 2-1 (Inventory of Exposed
Materials). Southport personnel have eliminated many sources by storing and using most materials,
and conducting most activities, inside or under a roof. The Southport plant has a Spill Prevention,
Control, & Countermeasures (SPCC) Plan which addresses oil spill prevention. Spill response
procedures are contained in Appendix F to this Plan. Trained personnel and appropriate materials are
available at the plant site to respond to minor spills. For any spills which enter the storm drain, or are
estimated to be beyond the plant's ability to contain and remediate, a contractor would be notified to
assist.
The information in the following paragraphs regarding spill planning is provided as reference for
Southport plant personnel.
Spill cleanup materials are maintained within the plant's Warehouse and in the R.O. Building (see
Figure 1-2 for the locations of the spill cleanup materials). These locations are inspected semi-
annually and replenished as needed. The materials typically include absorbent sheets, pillows, and
booms, as appropriate. In addition, an adsorbent material such as oil -dry or vermiculite is available at
all times.
In the event of a spill, Southport personnel follow the release response and reporting procedures in
Appendix F. Outside assistance for cleanup may be required. Recovered oily materials will be
disposed of in accordance with North Carolina and EPA regulations. Table 2-2 contains emergency
telephone notification numbers, including the number for the plant's emergency response contractor.

5.0 PREVENTATIVE MAINTENANCE AND GOOD HOUSEKEEPING PROGRAM
Southport plant personnel regularly maintain and keep in a clean, orderly manner, areas which may
contribute pollutants to storm water discharges. Good housekeeping procedures implemented at the
facility include the following:
Perform general weekly inspections of facility and equipment areas to maintain a safe
and trash free environment. Sweeping of paved areas is performed as needed.
2. Routinely inspect exposed plant equipment for leaks or conditions that could lead to
discharges of chemicals or petroleum products.
Proper inventory control procedures to insure that stored chemicals and petroleum
products are maintained at the minimum level necessary.
4. Proper material storage practices to ensure that materials are stored in containers
adequate for the locations, such that corrosion and deterioration of the containers is
minimized. This includes proper labeling of all containers and maintenance of MSDS
on materials stored.
The preventive maintenance program for the facility includes conducting semi-annual inspections and
performing any required maintenance on the storm water management devices, equipment, and
systems to prevent the discharge of pollutants to surface waters. In addition, bulk storage tanks,
transformers, and heavy equipment are inspected on a semi-annual basis. Records of the semi-annual
inspections are kept at the plant by the Senior Advisor, Environmental.
24

Southport Plant SWPP Plan November 24, 2014
6.0 EMPLOYEE TRAINING
Qualified plant personnel conduct annual training programs for employees responsible for any aspect
of storm water management, including those individuals responsible for implementing activities
identified in this Plan. This training will inform responsible personnel of the components and goals of
this Plan and will address topics related to storm water management, such as:
1. Good housekeeping;
2. Spill prevention and response; and
3. Material handling and storage practices.
In addition, each member of the plant's Pollution Prevention Team will undergo initial training on the
Plan prior to implementation. If a member joins the Team after the Plan has been implemented, they
will be trained prior to becoming listed in the Plan as a Team member. Where possible, employee
training under the Plan can be conducted in conjunction with training under other regulatory programs
(e.g, SPCC Plan training). Currently, Plan training is conducted at least annually through the safety
meeting program. Employees attending Plan training will sign an attendance roster. A manager and/or
section leader will follow up with employees who were not in attendance at the Plan training. Records
of the training programs will be maintained on file at the plant by the Senior Advisor, Environmental.

November 24, 2014
8.0 PLAN AMENDMENT
Southport staff will amend this 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 this Plan will be reviewed and updated on an annual basis. The annual update
will 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 will include re -certification that the
stormwater outfalls have been evaluated for the presence of non-stormwater discharges. Each annual
update will include a re-evaluation of the effectiveness of the BMPs listed in the BMP Summary of
the Stormwater Management Plan. Appendix D contains the annual update checklist.
27

Southport Plant SWPP Plan November 24, 2014
9.0 FACILITY INSPECTION PROGRAM
This Plan requires semi-annual visual inspections, as discussed below. The permit contains a
requirement to conduct inspections on at least a semi-annual basis, in Part II.A.8 of NPDES
Stormwater Permit NCS000348:
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 Part II B,
C and D of this permit.
To ensure compliance is maintained, qualified plant personnel will conduct a semi-annual visual
inspection of storm water management devices and facility equipment and systems that could
contribute to storm water pollution if they break down or otherwise fail. The semi-annual visual
inspections will also include inspections of all other areas identified in Figure 1-2 and Table 2-1 that
contain potential storm water pollutants (e.g., loading/unloading areas, fuel piles and conveyors, and
oil storage areas). As specified in the permit, an inspection will be conducted at least once during the
first half of the year (January to June), and at least once during the second half (July to December).
Semi-annual inspections will also be performed on oil and chemical bulk storage tanks. The Visual
Inspection Checklist (Appendix C) will be used in conducting these inspections, and the completed
checklists will be maintained by the Senior Advisor, Environmental. In addition, significant spills or
leaks discovered during the visual inspection will be noted in Appendix E of this Plan. Visual
inspections are a constant part of the preventive maintenance program at the Southport plant. Work
orders are generated on a daily basis and are the responsibility of the supervisor of the department
under which the work order falls.
28

11.0 POLLUTION PREVENTION TEAM
Appendix A identifies individuals within the facility organization who have been designated as
members of the facility Pollution Prevention Team. Team members are responsible for implementing
and maintaining this Plan.
The number of members on the team will vary depending on the size of the facility. As a standardized
approach, the Plant Manager and the Senior Advisor, Environmental assigned to the facility are core
members of the team and are listed in Appendix A. The Plant Manager is encouraged to assign
additional site members to the team as part of their employee involvement initiative. Additional
Pollution Prevention Team members and their responsibilities are listed in Appendix A.
The Plant Manager is ultimately responsible for the implementation of this Plan. The Plant Manager is
accountable for the prevention of spills and leaks that could adversely impact surface water or ground
water. The Plant Manager is responsible for ensuring that:
1. The Plan is implemented, maintained, and amended at the intervals required in the Plan;
2. Appropriate measures and controls (BMP's) are implemented and maintained;

12.0 ANALYTICAL MONITORING REQUIREMENTS
Permit No. NCS000348 contains analytical monitoring requirements that apply to each stormwater
outfall at the plant. Stormwater sampling is required to be conducted at each outfall twice per year,
during representative storm events. These requirements, excerpted from the permit, are shown on the
following 5 pages.

Southport Plant SWPP Plan
November 24, 2014
SECTION B. ANALYTICAL MONITORING REQUIREMENTS
Pennit No. NCS00348
Analytical monitoring of stun nwater discharges shall be performed as specifi cd in Table 1. All
analytical monitoring shall be perfunned during a representative storm event. The required
monitoring will result in a tninimurn often analytical samplings being conducted over the terns of
the permit at each stonnwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 4.1 inches of nainfall. 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 tip to 14 hours. For
example, Wit rains but stops before producing any collectable discharge, a sample may be collected if the.
next rain producing a dischar a begins within 10 hours.

APPENDIX F Southport Plant
Revision: 2
Release Response and Reporting Procedures Date: November24,2014
"Release" — defined in this Plan as any accidental or intentional spilling, leaking, pumping, pouring,
emitting, emptying, discharging, ejecting, escaping, leaching, dumping, or disposing into the
environment. Liquid or solid materials that escape their primary containment (i.e., tank, tote,
container, etc.) and discharge into a secondary containment system are not a Release unless the
regulated chemical subsequently volatilized into the air.
"Spill" — defined in this Plan as synonymous with release.
Effective spill and release response and reporting procedures are important because they provide for
rapid response to mitigate the impact of a release. These procedures describe the following measures
that will be implemented upon discovery of a significant release:
1. Assess the risk;
2. Control the release to the extent possible;
3. Report the release to management and government agencies;
4. Clean up the impacted area as soon as possible; and,
5. Follow up with preventive measures.
The Southport Plant's Emergency Response Manual provides additional guidance and procedures
for dealing with emergency situations, including releases of significant materials.
I. PRE -PLANNING
The Plant Manager or designee should familiarize facility personnel with all aspects of release
reporting, including the types of chemicals at the facility that must be reported when released, the
procedure for making telephone notifications, and the agencies that must be contacted. The Plant
Manager or designee should also ensure that the list of agencies, emergency response contractors, and
emergency telephone numbers found in Table 2-2 of this Plan are readily available and up to date.
IL ASSESS THE RISK
The risks presented by a release will be assessed the moment a release is observed or discovered.
Risks can change throughout an emergency, therefore, assessing the risk will continue throughout the
duration of the incident. Employees should react according to their level of training. Refer to the
facility's Hazardous Material Response Plan to determine the response level of facility personnel.
A major release may require employees to evacuate and response may be provided only by outside
emergency response services that are equipped and trained to handle a major release.
III. CONTROL THE RELEASE
Every effort will be made to keep a spill from leaving the site boundaries via foundation drains, catch
basins, and manholes. Facility personnel will immediately commit all necessary manpower,
equipment, and materials required to prevent the spill from reaching waterways, stormwater draining
structures, or sewers.
F - 1

Southport Plant SWPP Plan
November 24, 2014
A. Types of Control Methods
Methods available for controlling spills include:
• Absorption - Use materials such as clay, sawdust, or vermiculite to absorb liquids. When
absorbents become contaminated, they retain the properties of the absorbed liquid. Therefore,
they must be disposed of accordingly.
• Covering - Spill areas can be covered with appropriate materials, such as plastic sheets, until
cleanup efforts can be completed.
• Dikes, dams, diversions, and retention - These temporary or permanent physical barriers can
be used to retain spills, change the direction of flow of the liquid, or minimize storm water
run-on to the impacted area.
• Over packing - Leaking drums can be placed in larger containers to hold the leaking liquid.
• Plug and patch - Compatible plugs and patches can temporarily stop the flow of materials
through small holes.
• Transfer - Liquids can be transferred from a leaking or damaged container or tank. Care must
be taken to ensure transfer hoses and fittings are compatible with the liquid. When flammable
liquids are transferred, proper concern for grounding must be observed.
B. Implementing Control Methods
The alternative control methods listed above will be implemented in the following order unless
directed otherwise by the Plant Manager or designee:
• Spills confined to immediate area - Place sorbent materials in direct contact with the liquid,
working inward from the farthest point of progression of the liquid. The quicker the response,
the smaller the contaminated area.
• Spills escaping from immediate area - If liquid begins to spread outside of the immediate area,
attempts should be made to stop the flow before it enters a foundation drain, catch basin, or
manhole by building up sorbent materials to dike the sewer entrance. As an alternative, sewer
mats or sheets of plastic should be placed over sewer entrances and weighed down with heavy
objects or gravel. In the event the liquid enters a sewer, sorbent materials should be used at the
discharge points or in the storm and sanitary sewers to collect the material. Facility personnel
should consider, as appropriate, assistance from neighboring industry, outside contractors, oil
skimmers, backhoes, pumps, emergency dikes, oil absorbent, hay bales, booms, etc. as
necessary.
IV. REPORT THE RELEASE
Immediately after initiating appropriate emergency measures to confine the release, facility personnel
should report any environmental release to management and to government agencies, as required. The
following sections describe the procedure to be used for reporting spills/uncontrolled environmental
releases to government agencies.
F - 2

Southport Plant SWPP Plan November 24, 2014
A. Reporting Scope
This procedure applies to virtually every spill or uncontrolled release of a significant material at the
facility because environmental regulations apply to the release to the environment of a regulated
chemical above a Reportable Quantity or in excess of a reporting threshold. The Plant Manager or
designee will consult with the Senior Advisor, Environmental to confirm the reporting requirements
for each spill event. The Reportable Quantities for regulated chemicals used at the Southport Plant are
summarized below:
• Oil and petroleum products — For reporting to EPA and NC DENR: one (1) barrel (i.e., 42
gallons);
• Hazardous wastes (ignitable, corrosive, or reactive) — one hundred (100) pounds of the
regulated chemical (Note: the Southport Plant is a conditionally exempt small quantity
generator and does not store these types of materials);
• Sodium hypochlorite — one hundred (100) pounds;
• Sodium hydroxide (a.k.a., caustic soda) — one thousand (1,000) pounds; and
• Sulfuric acid — one thousand (1,000) pounds.
B. Reporting Responsibility
The Plant Manager or designee is responsible for making all necessary telephone notifications when a
release to the environment has occurred. The Plant Manager or designee may delegate individual
reporting tasks to other Southport Plant staff, but overall reporting responsibility remains with the
Plant Manager or designee. The facility Emergency Response Plan occurs:
1. Line Management;
2. Senior Advisor, Environmental;
3. Local Sewer Authority;
4. Local Fire Department;

The following procedures should be followed when making telephone notifications to government
agencies. Telephone numbers may be found in Table 2-2 of this Plan.
1. Report Immediately — NC DENR must be notified no later than one (1) hour after
Southport Plant staff learns of the release.
2. Start with local agencies first - When making emergency telephone notifications, start
with local agencies first, and then proceed to contact state agencies, and lastly federal
agencies. This order of priority is important because local agencies are impacted the most. As
these notifications are made, let the next agency contacted know who has been previously
contacted. This will help streamline communications should the various agencies begin to

contact each other. Spills/releases into the local sewer system must be reported to the local
sewer authority.
3. What to report - When making a telephone notification, do not speculate. Report only the
facts as known at the time the call is made. Be prepared to provide the following information:
a. Your name and telephone contact number(s);
b. Name and location of the facility (i.e., Southport Plant located at 1281 Power Plant
Road SE, Southport, North Carolina);
c. Date and time the incident began and ended, or the estimated time of continuation if
the release is continuing at the time of notification;
d. Extent of any injuries and identification of any know personnel hazards which
response agencies may encounter (e.g., is the material an Extremely Hazardous
Substance, etc.);
e. The common or scientific name of the released material; US Department of
Transportation hazard classification; and the best estimate of any or all released
material;
f. A brief description of the incident that is sufficient to allow response agencies to
formulate the level and extent of response activities; and
g. The names and telephone numbers of the person or persons to be contacted for
further information.
4. Keep a telephone notification log - It is important to document calls made to government
agencies. Be sure to fully document telephone notifications as well as other information about
the environmental incident. Notification information to be documented includes:
a. Date/time of call;
b. Agency and official contacted;
c. Who made the call;
d. Any comments made by officials, including any reference number assigned to the
incident by the agency, and
e. As soon as possible, after making these agency notifications, notify Line
Management, Senior Advisor, Environmental, and affected Southport Plant
customers.
5.Other notifications may be required - Additional notifications may be necessary
depending on the nature of the release and substance involved. Written notification to NC
DENR is required within seven (7) calendar days after the telephone notification.

Southport Plant SWPP Plan November 24, 2014
V. CLEAN UP THE AFFECTED AREA
Cleanup should begin as soon as possible. The Plant Manager or designee should enlist all available
resources to stop the spill or release. The local spill response contractor, Moran Environmental
Recovery (see Table 2-2 for contact information), can provide typical containment and clean up
services is familiar with the site and has entered into a contractual agreement with the facility.
The Senior Advisor, Environmental should be contacted to determine and arrange for proper
treatment, storage, and disposal of spilled materials. Spill cleanup contractors should not be allowed to
dispose of spill residue until the Senior Advisor, Environmental has identified an approved or
acceptable disposal facility. The Senior Advisor, Environmental will also assist in determining the
extent of remediation required.
VI. FOLLOW UP ACTION
The Plant Manager or designee shall review the cause of the spill or release and initiate appropriate
corrective actions to prevent similar occurrences. Additionally, all spill materials and sorbent material
must be restocked. The Senior Advisor, Environmental will be responsible for preparing and
submitting any written follow-up reports required by government agencies and for reporting the
release to Senior Management. The type of follow up report required will vary, depending upon the
material spilled, the quantity spilled, whether the material was contained and/or cleaned up, and
whether the spill constituted a public health threat.

non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found. in. Part III, Standard Conditions, Section
B, Paragraph 3. The peirnittee shall re -certify annually that the stormwater
outtalls have been evaluated for the presence of non-stormwater discharges.
2. Stormwater Management Plan. The stoiniwater 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
nonstructural. measures. The storrnwater management plan, 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 stormwater. Wherever practical, the perinittee shall

controlled by manually activated valves or other similar devices (which shall be
secured closed with a locking mechanism), and any stormwater that accumulates
in the containment area shall be at a minimum visually observed for color, foam,
outtall 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 the material stored within the containment area. 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.
(c) BMP Summary, A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs

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 storrnwater runoff through spills or exposure of materials associated with the
facility operations, The SPRP must be site storinwater specific. Therefore, an oil Spill
Prevention Control and Countertneasure plan (SPCC) may be a component of the SPRP,
but may not be sufficient to completely address the storinwater 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 stonirwater control systems, stonuwater discharge outfalls, all on -site and adjacent
surface waters and wetlands, industrial activity areas (including material storage areas,

program shall establish schedules of inspections, maintenance, and housekeeping
activities of stoirnwater control systems, as well as facility equipment, facility areas, and
facility systems that present a potenitial for stolmwater 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.
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

discharges at multiple outfalls, the DWQ may grant representative outfall status. Representative outfall
status allows the permittee to perform analytical monitoring at a reduced number of outfalls.
21. Rinse Water Discharge
The discharge of rinse water from equipment cleaning areas associated with industrial activity. Rinse
waters from vehicle and equipment cleaning areas are process wastewaters and do not include washwaters
utilizing any ."e of detergent or cleaning agent.
22. Secondary Containment
Spill containment for the contents of the single largest tank within the containment structure plus sufficient
freeboard to allow for the 25-year, 24-hour storm event.
23. Section 313 Water Priority Chemical
A chemical or chemical category which:
a. Is listed. in 40 CFR 372.65 pursuant to Section 313 of Title III of the Superhind Amendments and
Reauthorization Act (SARA) of 1986, also titled the Emergency Planning and Conununity Right -
to -Know Act of 1986;
b. Is present at or above threshold levels at a facility subject to SARA Title III, Section 313 reporting
requirements; and
C. That meets at least one, of the following criteria:

Permit No. NCS00348
(1) Is listed in Appendix D of 40 CFR part 122 on Table 11 (organic priority pollutants),
Table III (certain metals, cyanides, and. phenols), or Table IV (certain toxic pollutants and
hazardous substances);
(2) Is listed as a hazardous substance pursuant to section 311 (b)(2)(A) of the CWA at 40
CFR 116.4; or
(3) Is a pollutant for which EPA has published acute or chi-onic water quality criteria.
24. Severe Property Dan ----
Means substantial physical damage to property, damage to the control facilities,, which causes them to
become inoperable, or substantial and permanent loss of natural resource-,. which can reasonably be
expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused
by delays in production.
25. Significant Materials
Includes, but is not limited to: raw materials; fuels; materials such as solvents, detergents, and plastic
pellets; finished materials such as metallic products; raw materials used in food processing or production;
hazardous substances designated under section 101(14) of CERCLA; any chemical the facility is required to
report pursuant to section 313 of Title Ill of SARA; fertilizers; pesticides; and waste products such as ashes,
slag and. sludge that have the potential to be released with stormwater discharges.
26. Sig
nificant Spills
Includes, but is not limited to: releases of oil or hazardous substances in excess of reportable quantities
under section 311 of the Clean Water Act (Ref- 40 CFR 110.10 and CFR 117.21) or section 102 of
CERCLA (Ref. 40 CFR 302.4).
27. Stormwater Runoff
The flow of water which results from precipitation and which occurs immediately following rainfall or as a
result of snowmelt.
28. Stormwater Associated with Industrial Activity
The discharge from any point source which is used for collecting and conveying storniwater and which is
directly related to manufacturing,., processing or raw material storage areas at an industrial site. Facilities
considered to be engaged in "industrial activities" include those activities defined in 40 CFR 122.26(b)(14).
The term does not include discharges from facilities or activities excluded from the NPDES program.
29. Stormwater Pollution Prevention Plan
A comprehensive site -specific plan which details measures and practices to reduce storniwater pollution and
is based on an evaluation of the pollution potential of the site.
30. Ten Year Design Storm
The maximum 24 hour precipitation event expected to be equaled or exceeded on the average once in ten
years. Design stone information can be found in. the State of North Carolina Erosion and Sediment Control
Planning and Design Manual.
Part VI Page 4 of 5 Pages

Permit No. NCS00348
1. Total Flow
The flow corresponding to the time period over which the entire storm event occurs. Total flow shall be
either; (a) measured continuously, (b) calculated based on the amount of area draining to the outfall, the
amount of built -upon (impervious) area, and the total amount of rainfall, or (c) estimated. by the
measurement of flow at 20 minute intervals during the rainfall event.
32. Total MaJIrnum.Dailv Load (TMDL)
A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet
water quality standards, and an allocation of that amount to the pollutant's sources. A TMDL is a detailed
water quality a,,-,sessment that provides the scientific foundation for an implementation plan. The
implementation plan outlines the steps necessary to reduce pollutant loads in a certain body of water to
restore and maintain water quality standards in all seasons. The Clean Water Act, Section 303, establishes
the water quality standards and TMDL programs.
Z�I
33. Toxic Pollutant
Any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act.
34. Upset
Means an exceptional incident in which there is unintentional and temporary noncompliance with
technology based permit effluent limitations because of factors beyond the reasonable control of the
permittee. An upset does not include noncompliance to the extent caused by operational error., improperly
designed treatment or control facilities, inadequate treatment or control facilities, lack of preventive
maintenance, or careless or improper operation.
35. Vehicle Maintenance Activity
Vehicle rehabilitation, mechanical repairs, painting, fueling, lubrication, vehicle cleaning operations, or
airport deicing operations.
36. Visible Sedimentation
Solid particulate matter, both mineral and organic, that has been or is being transported by water, air,
gravity, or ice from its site of origin which can be seen with the unaided eye.
37. 25-year 24 hour storm event
The maximum 24-hour precipitation event expected to be equaled or exceeded, on the average, once in 25
years.
