DIESEL FUEL AND GASOLINE STORAGE
Diesel fuel and gasoline is stored at the plant in several different tanks and containers at the
plant. The diesel fuel is primarily used as fuel for emergency diesel generators at the plant.
The diesel fuel and gasoline is used to fuel plant vehicles and miscellaneous equipment. The
largest containers at the plant are two 175,000 gallon underground diesel fuel storage tanks
located north of the plant, and two 110,000 gallon field -erected aboveground diesel fuel storage
tanks located in the southwestern area of the plant yard. The aboveground tanks are located
within a single common concrete secondary containment structure equipped with a closed drain
valve. Drainage from the containment discharges into the plant 10,000 gallon capacity
Oil/Water Separator. The plant contains eight additional aboveground diesel fuel tanks, one
aboveground gasoline tank, and numerous 55 gallon petroleum storage drums. The remaining
tanks are small, shop -fabricated steel tanks maintained at various locations around the plant.
The plant contains one 1,000 gallon underground diesel fuel storage tank at the Security
Building, and one 10,000 gallon underground diesel fuel storage tank and one 10,000 gallon
underground gasoline storage tank in the Mobile Equipment Area. The plant also maintains one
small diesel fuel tank and one small gasoline tank on a mobile fuel truck.
A complete listing of these containers, including inspection and testing requirements, secondary
containment descriptions and inspection requirements, and tanker unloading operation
requirements are described in detail in the Harris Nuclear Plant SPCC Plan. All diesel fuel and
gasoline storage tanks are provided with some means of passive secondary containment or are
integral double -walled containers as described in detail in the Harris Nuclear Plant SPCC Plan.
All external containments are inspected prior to being manually drained in accordance with the
SPCC Plan. Secondary containments either drain into the plant 10,000 gallon capacity
Oil/Water Separator, or onto the plant yard. Mobile tanks are stored in areas that drain to the
Oil/Water Separator while in standby mode.
Refueling operations for all diesel fuel and gasoline containers are conducted in constant
attendance in accordance with plant procedures and the Harris Nuclear Plant SPCC Plan.
Tanker trucks are brought on -site to refill the two 175,000 gallon underground diesel fuel
storage tanks and the two aboveground 110,000 gallon diesel fuel storage tanks. Tanker
unloading into the two 175,000 gallon underground storage tanks, and into the two 110,000
gallon aboveground storage tanks, is conducted on a concrete containment pad adjacent to the
tanks. The containment is equipped with open drains to the Oil/Water Separator. Tanker trucks
are also brought on -site to refill the other aboveground and underground diesel fuel and
gasoline tanks. These tankers unloading operations are conducted adjacent to the containers
and in constant attendance in accordance with plant procedures. Prior to filling any container,
tank levels are verified by electronic high-level and low-level annunciators, visual sight glasses,
or are otherwise verified as described in the plant SPCC Plan.
Page 8 of 88

STORM WATER POLLUTION PREVENTION PLAN
Revsion 5 May 2020
The plant contains diesel fuel piping primarily associated with the delivery of diesel fuel from the
two 110,000 gallon aboveground diesel fuel storage tanks to the emergency diesel generator
system, and to other locations and systems. The piping is located aboveground or within
concrete trenches. None of this piping is in contact with the soil. Portions of this piping are
located within the secondary containment structure surrounding the tanks or at the fuel
forwarding skid within the containment pad for the tanker unloading station. All aboveground
piping outside of these concrete containments, and all piping within the concrete trenches, is
provided secondary containment by open drains to the Oil/Water Separator. Diesel fuel transfer
operations from the tanks to the emergency diesel generator system is an automated process.
Facility operations personnel conduct daily routine facility walk -downs to observe all
aboveground piping, valves, expansion joints, flange joints, and structural supports.
There are no changes warranted to reduce the potential for impacts to storm water runoff
associated with diesel fuel and gasoline storage practices or tanker unloading operations at the
facility. All diesel fuel and gasoline containers are in compliance with the plant SPCC Plan.
Used oil is collected and stored in eleven small tanks and containers at the plant. The largest
used oil tanks are one 4,000 gallon steel tank and one 2,000 steel gallon tank in the Mobile
Equipment Area. These two tanks are within a common concrete containment structure. There
is a 1,000 gallon steel used oil tank adjacent to the .Oil/ Water Separator that collects used oil
removed by the separator. This tank is within the same concrete containment pad as the
separator. There is a 1,000 gallon steel used oil tank adjacent to the Emergency Diesel
Generator Building and within a concrete containment structure. There are three 220 gallon
poly used oil containers at the plant. Two of these containers are within a common metal
containment bin on a covered concrete pad at the Paint Shop. The remaining container is
within a concrete containment structure in the Mobile Equipment Area. The plant has a 1,000
gallon steel used oil tank mounted on a mobile trailer. While in standby mode the trailer is
maintained in an area of the plant with yard drains that discharge into the Oil/Water Separator.
There is a 100 gallon hydrogen seal oil drain tank within a concrete containment structure
adjacent to the Turbine Building, and a 200 gallon oil filter drain tank inside the Mobile
Equipment Building. The plant also maintains two 55 gallon used cooking oil drums maintained
within a poly containment shelter at the east end of the Service Building.
A complete listing of all used oil tanks, including inspection and testing requirements, secondary
containment descriptions and inspection requirements, and tanker loading operation
requirements are described in detail in the Harris Nuclear Plant SPCC Plan. All external
containments are inspected and manually drained in accordance with the SPCC Plan.
Secondary containments either drain into the plant 10,000 gallon capacity Oil/Water Separator,
or onto the plant yard. Mobile tanks are stored in areas that drain to the Oil/Water Separator
while in standby mode. Tanker trucks are brought on -site to load used oil as needed from the
Page 9 of 88

STORM WATER POLLUTION PREVENTION PLAN
Revsion 5 May 2020
various used oil tanks. The tanker loading operations are conducted adjacent to the containers
and in constant attendance in accordance with plant procedures.
There are no changes warranted to reduce the potential for impacts to storm water runoff
associated with used oil storage practices or tanker loading operations at the facility. All used
oil containers are in compliance with the plant SPCC Plan.
LURE OIL STORAGE
The plant has three lube oil storage tanks consisting of one 14,000 gallon Turbine Generator
Batch Oil Tank and two 1,500 gallon Turbine Lube Oil Sump Tanks. All three tanks are located
within concrete containment basins inside the Turbine Building. The inspection and testing
requirements for these lube oil tanks is described in detail in the Harris Nuclear Plant SPCC
Plan. There are no changes warranted to reduce the potential for impacts to storm water runoff
associated with these lube oil tanks.
OIL -FILLED EQUIPMENT AND SYSTEMS
Oil -filled equipment and systems at the plant includes lubrication oils, mineral oils and hydraulic
oils maintained within closed conduit systems. These oils are used in hydraulic systems,
lubricating systems, gear boxes, machining coolant systems, heat transfer systems,
transformers and circuit breakers. Oil -filled equipment and systems, including container
inspection requirements and secondary containment descriptions and inspection requirements,
are described in detail in the Harris Nuclear Plant SPCC Plan.
The plant contains four lube oil and hydraulic oil reservoir systems located inside the Turbine
Building. These reservoir systems are not exposed to storm water. Any oil release occurring
from these systems will enter open floor drains that discharge into the plant Oil/Water
Separator.
The largest oil -filled equipment containers exposed to storm water are large transformers
containing mineral oil and located in the Transformer Yard on the east side of the Turbine
Building. This equipment consists of three 9,180 gallon Start -Up Transformers, four 7,780
gallon Main Step -Up Transformers, and two 5,500 gallon Auxiliary Transformers. All of these
transformers are within a concrete containment sump equipped with a manually operated
dewatering pump. Containment contents are inspected in accordance with the plant SPCC Plan
prior to dewatering, and sump contents are pumped to the plant Oil/Water Separator. There are
no changes warranted to reduce the potential for impacts to storm water runoff associated with
the large transformers.
Smaller oil -filled equipment containers exposed to storm water include numerous pad -mounted
service transformers containing mineral oil located at various locations around the plant. These
Page 10 of 88

STORM WATER POLLUTION PREVENTION PLAN
Revsion 5 May 2020
transformers are used to provide power to the various buildings and facilities at the plant, and
are generally not provided with any means of passive secondary containment. Any mineral oil
release occurring from these service transformers would result in failure of the unit and
subsequent loss of power. The plant relies on system monitoring, frequent inspections,
preventative maintenance, and active containment measures as described in the plant SPCC
Plan to contain any potential release occurring from these transformers. A mineral oil release
from these units will typically discharge vertically into the underlying conduit penetrations which
will provide some degree of containment. The potential for storm water impacts associated with
mineral oil releases from any of these uncontained pad -mounted transformers is minimal, and
could be reduced by the installation of dedicated secondary containments with manually
operated drain valves or open drains to the Oil/Water Separator.
CHEMICAL STORAGE AND HANDLING
Various chemicals are used at the plant for water treatment and other purposes. Bulk
chemicals are delivered by tanker trucks and unloaded into respective storage tanks at
designated locations. Smaller chemical containers and drums are delivered to the receiving
area of Warehouse 9 for storage or subsequent transport via company vehicles to the Water
Treatment Building, Paint Shop, Bulk Warehouse, Chemical Warehouse, the Sewage Treatment
Plant, and other locations. Plant personnel are trained in safe forklift usage, safe handling of
chemicals, and proper use of spill containment and cleanup materials. Spill kits are located at
receiving areas.
Two 5,500 gallon sodium hypochlorite tanks, one 5,600 gallon phosphoric acid tank, three 4,500
gallon water treatment chemical storage tanks and other smaller chemical containers are used
for water treatment and analysis purposes at the Cooling Tower. The sodium hypochlorite tank
and other small tanks and containers are within a concrete containment. The containment can
be drained to the yard drainage system or can be pumped into the Cooling Tower basin. Small
containers of chemicals used for analysis are stored inside the chemical storage building.
Four bulk chemical storage tanks, consisting of a 10,800 gallon caustic tank, a 7,500 gallon
sulfuric acid tank, a 1,500 gallon empty ammonia tank, and a liquid nitrogen to gaseous nitrogen
tank are located at the south end of the Turbine Building. These tanks are within containments
that can be drained to the yard drainage system or to a sump that discharges to the Oil/Water
Separator. An 8,315 gallon sulfuric acid storage tank is located at the east end of the Water
Treatment Building. This tank is within a concrete containment with an open drain to a sump
that pumps to the Neutralization Basin. Sodium carbonate, sodium hypochlorite, sodium
hydroxide, and water treatment polymers are stored in tanks and containers at the Sewage

containment structures with open drains to other containment or treatment systems, or are
stored inside buildings. All external containments with drain valves are inspected prior to boing
manually draining. All chemical deliveries are conducted adjacent to the containers or at
receiving areas in constant attendance and in accordance with plant procedures. Chemical
container levels are verified prior to initiating any tanker unloading operation. There are no
changes warranted to reduce the potential for impacts to storm water runoff associated with the
storage and handling of chemicals.
WASTE HANDLING AND STORAGE
Waste chemicals and oils produced inside the protected area of the plant is typically transported
to and processed in the chemical processing area of the Paint Shop. These materials are
stored within a covered concrete containment area with open drains to the Oil/Water Separator.
Waste chemicals produced outside the protected area of the plant are typically transported to,
processed and stored in Warehouse 6. Waste oils produced outside the protected area of the
plant are typically transported to the used oil tanks in the Mobile Equipment Area.
Hazardous materials are accumulated in designated satellite waste storage areas at the plant.
All satellite accumulation areas are either under shelters or are inside buildings. All hazardous
waste generated at the plant is eventually transported to and stored in the Central Hazardous
Waste Storage Area located under a shelter attached to the Chemical Warehouse.
Dumpsters and roll -off containers are used at certain locations to collect inert materials and
solid waste for disposal. No liquids or other materials that could potentially impact storm water
are disposed of in external dumpsters. Two closed trash compactors are located west of the
Chemical Warehouse. Recyclable waste materials are collected in covered storage containers
at several locations inside buildings.
There are no changes warranted to reduce the potential for impacts to storm water runoff
associated with waste handling and storage.
EXTERNAL STORAGE, LAYDOWN AND PARKING AREAS
Inert materials such as miscellaneous wood, structural steel, cable, empty drums and other
metal components are stored at various external laydown yard areas at the plant. These
laydown areas are typically paved or gravel -surfaced. No liquids or materials that could
potentially impact storm water are stored on external laydown areas. Cranes and other mobile
equipment are parked on the crane laydown yard and in other external parking and storage
areas. This equipment can contain oils, fuels, hydraulic fluids and other materials that represent
potential storm water impacts. Plant employees are trained to promptly report and respond to
spills.
Page 12 of 88

STORM WATER POLLUTION PREVENTION PLAN
Revsion 5 May 2020
Other materials such as soil, sand, gravel, compost, concrete and asphalt may be stockpiled at
certain locations on a temporary basis until the material can be recycled, reused or properly
disposed of off -site. Stockpiled materials such as soil that could potentially result in the
mobilization of sediments when exposed to rainfall are covered, stabilized by temporary or
permanent seeding or are otherwise provided with necessary sediment control measures.
Drainage areas containing external storage, laydown and parking areas are described in
Appendix B. The potential for storm water impacts associated with these external areas could
be reduced by covering materials such as soil, gravel, treated lumber, flaking painted surfaces
and other materials that represent the greatest potential for such impacts, by regular inspections
and maintenance of mobile equipment, and by maintaining mobile equipment inside temporary
containments while parked. Constructing permanent shelters over these external areas to
prevent contact with storm water is cost prohibitive.
SECURITY TRAINING AND FIRING RANGE
The plant maintains a designated facility for security training purposes that includes an external
firing range. The range is located west of the plant on the north side of the Emergency Service
Water Intake Canal. Lead -based ammunition is routinely fired into bullet traps at the range.
Storm water runoff from this area flows south and southwest overland into the adjoining
Emergency Service Water Intake Canal. The embankment soil pH is routinely monitored and
maintained within a range to prevent the lead from becoming soluble. Security personnel
maintain an inventory of expended rounds fired and routinely harvesting lead from bullet traps or
the soil.
There are no changes warranted to reduce the potential for impacts to storm water runoff
associated with the security training and firing range. Constructing permanent shelters over the
firing range to eliminate exposure to rainfall is cost prohibitive.
Duke Energy continuously pursues strategies to holistically manage the exposure of storm
water to power generation, waste disposal, and facility management operations. These efforts
consider the technical and economic feasibility of changing the methods of operations and/or
storage practices. The details from the planning, design, and construction of such improvements
shall be incorporated into the SWPPP upon completion.

2.2.2 Secondary Containment Requirements and Records
NPDES Permit Reference: Part 1, Section A 21.2b(2)
The plant manages numerous oil -based liquids and non -oil based liquids and chemicals which
are critical to power generation and transmission, water treatment, waste handling and
treatment, and operation of vehicles and equipment.
The Harris Nuclear Plant is subject to the requirements of U.S. Environmental Protection
Agency (EPA) Oil Pollution Prevention Regulation 40 CFR Part 112 because the oil storage
capacity at the facility exceeds 1,320 gallons and the proximity to waters of the United States.
As a result, the facility maintains a Spill Prevention, Control, and Countermeasures (SPCC)
Plan pursuant to, 40 CFR Part 112. This plan addresses secondary containment, inspections
and record keeping requirements for all oil containers of 55 gallon capacity and greater. A copy
of the SPCC is not included in the SWPPP as the document is actively managed at all times for
evolving site conditions; however, a current version is maintained in the Nuclear Fusion
document data base and a version with mark-ups is maintained in the office of the Site
Environmental Coordinator(s) and referenced herein.
Pursuant to this section of the permit, secondary containment is required for the 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 spills and leaks from contaminating storm water
runoff. Secondary containments shall be sized to contain the full capacity of the single largest
container within the containment structure. Secondary containments exposed to precipitation
shall also have additional capacity to contain the 25-year, 24-hour storm event. This additional
capacity requirement shall take into consideration any storm water runoff entering the
containment structure from upland areas if applicable. Secondary containments draining into
storm water conveyance systems or onto the ground surface shall be equipped with manually -
operated, lockable or otherwise secured drain valves or dewatering pumps. Flapper -type valves
shall not be used.
Accumulated storm water within secondary containments shall be visually inspected for color,
foam, outfall staining, presence of sheen, oils or chemicals prior to release in accordance with
the frequencies specified in the plant SPCC Plan. Inspections will include observation for leaks,
condition of containment, valve drain closure and locking, and presence of excessive debris and
sediment. Inspection records shall be maintained at the facility. Exterior containments exposed
to precipitation shall be inspected promptly after any significant rainfall event, and collected
water within containments shall be drained to maintain adequate spill storage capacity within the
containment.
A list of all liquids and chemicals and their associated secondary containment provisions are
provided in Appendix F. Documentation for periodic inspections for leaks and recordation of
accumulated storm water releases shall be placed in Appendix I.

2.2.3 Best Management Practices (BMPs) Summary
NPDES Permit Reference: Part 1, Section A 21.2b(3)
A number of best management practices are currently in place at the station. These BMPs were
instituted over a number of years as a result of various regulatory drivers and good
housekeeping objectives. While a chosen practice provides some level of pollution prevention
as it relates to the management of storm water discharges under this permit, the historic
rationale behind implementing such a practice is comprehensive of a number of contributing
factors. To document the ongoing implementation of these practices as part of the SWPPP,
Table 2 from the Industrial Storm Water Fact Sheet for Steam Electric Power Generating
Facilities (EPA-833-F-06-030) was reviewed and evaluated, and is provided in Appendix O. A
high-level review of the BMPs is provided below along with a rationale for implementation. The
detailed listing of these BMPs for each drainage area is provided in the outfall descriptions in
Appendix B where information regarding the industrial activities and significant sources of
pollutants are also compiled. The compiled information in the appendix captures an ongoing
assessment process for BMP selection and implementation.
The Site Environmental Coordinator(s) shall rely on Table 2 from EPA-833-F-06-030 for the
improvement, installation and implementation of BMPs to address data collected through
monitoring of storm water discharges. The Site Environmental Coordinator(s) may also rely on
other sources of information to develop and implement appropriate BMPs not specifically listed
in Table 2. This list of BMPs shall be reviewed and updated annually as new practices are
incorporated in the plan or warranted as a result of exceedances of analytical monitoring
benchmarks detailed in the permit.
FUGITIVE DUST EMISSIONS
The potential for fugitive dust to impact storm water runoff drives the need for emission
management practices. The station maintains an air permit with NCDEQ that includes the
control of fugitive dust emissions as a programmatic requirement. Fugitive dust emissions are
managed as necessary through a variety of BMPs that include restricting frequent traffic to
paved roadways, periodic wetting of haul roads, and permanent stabilization of dust generating
surfaces. Fugitive dust control is typically a contractual requirement of any contractors brought
on -site to perform services that may involve the creation of fugitive dust. Fugitive dust
generation is typically insignificant at the facility.
LOADING AND UNLOADING OF FUELS, OILS AND NON -OIL LIQUIDS AND CHEMICALS
The plant maintains numerous locations for the loading and unloading of fuels, oils and non -oil
liquids and chemicals. The potential for spills and leaks to release to storm drains or overland
drainage pathways to receiving waters presents a source of unauthorized discharges and
potential storm water contamination. Loading and unloading operations follow plant procedures,
the requirements specified in the plant SPCC Plan, and the requirements specified in the DOT
unloading/loading procedures 49 CFR Part 177, Subpart B.
