Enclosure 2 Item 4 - Summary of Best Management Practices
Section 2.2.3 Best Management Practices (BMPs) Summary
BEEP Storm Water Pollution Prevention Plan (SWPPP)

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 current list of all liquids and chemicals and their associated secondary containment provisions
is maintained in eTrac and is also provided in Appendix F. Documentation for periodic
inspections for leaks and recordation of accumulated storm water releases are documented in
Appendix I.
2.2.3 Best Management Practices (BMPs) Summary
1SW Permit Reference: Part It, Section A.2 (c)
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 0. 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.
12

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 station 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. BMPs utilized during loading and
unloading operations include constant attendance by qualified plant personnel, appropriate
training, verification of container levels prior to filling, and the close proximity of appropriate spill
response materials and resources. BMPs also include dedicated containment unloading
platforms at the 7-Day Diesel Fuel Storage Tank, the 14-Day Diesel Fuel Storage Tank, the
Security Emergency Diesel Generator, the Equipment Fuel Oil Storage Tank, and the
Equipment Gasoline Storage Tank. Any spill occurring during loading or unloading operations
within the protected area of the plant that cannot be contained in the immediate area by active
measures will flow through the storm drain system and be contained in the Storm Drain
Collection Basin.
ABOVEGROUND LIQUID STORAGE TANKS AND PIPING
The plant maintains numerous aboveground storage tanks for fuels, oils and non -oil liquids and
chemicals. Aboveground piping is present at certain locations, and is primarily associated with
the transfer of diesel fuel for operation of emergency diesel generators. The potential for spills
and leaks to release to storm drains or overland drainage pathways to receiving waters exists,
and presents a source for an unauthorized discharge and contamination of storm water. The
plant relies on a variety of BMPs to reduce the potential for leaks or spills to impact storm water.
13

BMPs utilized for the larger bulk storage tanks include either dedicated secondary containments
with secured manually -operated drain valves or pumps, dedicated secondary containments
equipped with integral oil skimmers that gravity drain into the Storm Drain Collection Basin, or
integral double -walled containment shells. BMPs utilized for smaller containers and drums
include maintaining the containers inside various buildings, on spill pallets or within containment
shelters. BMPs utilized for aboveground piping includes double -walling or protective coating
and wrapping for certain high risk fuel transfer piping. Additional BMPs utilized include bollards
and barriers to prevent vehicular impacts, tank level indicators to prevent overfilling and detect
leaks, routine inspections and maintenance of tanks, piping, valves and connections. Routine
inspection and integrity testing requirements for bulk oil tanks are specified in the plant SPCC
Plan.
OIL -FILLED ELECTRICAL EQUIPMENT
The plant maintains oil -filled electrical equipment at numerous locations. The potential for spills
and leaks to release to storm drains or overland drainage pathways to receiving waters exists,
and presents a source for an unauthorized discharge and contamination of storm water. The
plant relies on a variety of BMPs to reduce the potential for leaks or spills from this equipment to
impact storm water. The plant utilizes gravel -filled concrete containment pits equipped with oil
trap weirs that gravity drain into the Storm Drain Collection Basin as BMPs for the largest
transformers located in the Transformer Yard within the protected area. A lined, concrete
containment basin equipped with an oleophilic discharge valve is used for two large spare
transformers in the Switchyard area. BMPs utilized for uncontained electrical equipment located
within the plant Switchyard includes the spill retaining ability of the level, gravel -surfaced yard.
BMPs utilized for large transformers at the Caswell Beach Discharge Structure include a
partially -covered concrete containment structure equipped with an oil trap weir that gravity
drains into the Discharge Canal. Storm water runoff from the numerous oil -filled electrical
equipment locations outside of the protected area will discharge into either Nancy's Creek, the
Intake Canal, or the Discharge Canal. BMPs for all transformers at the facility include routine
inspections performed in accordance with the requirements specified in the plant SPCC Plan,
and system monitoring to detect any adverse conditions associated with the equipment.
CLEAN MATERIAL PROCESSING FACILITY
The plant maintains a Clean Material Processing Facility used for waste handling, monitoring
and storage. The facility is comprised of two buildings and surrounding laydown areas located
outside of the protected area. The first building is a central processing area used for monitoring
waste materials for low level radioactivity prior to leaving the site. A trash compactor is located
adjacent to the main building and is used for compacting routine trash generated at the plant.
The second building is used for segregating and storing chemical wastes, hazardous wastes,
waste oil, used fluorescent bulbs, batteries, paints, oily wastes, and other materials for
disposition. The potential for spills and leaks to release to storm drains or overland drainage
pathways to receiving waters exists, and presents a source for an unauthorized discharge and
contamination of storm water. Storm water runoff from this area eventually discharges into
Nancy's Creek via Outfall 007. BMPs utilized include maintaining most wastes and chemicals
14

inside the buildings that could potentially impact storm water, and interior curbed concrete floors
with dead-end sumps to retain any spills within the buildings. Additional BMPs utilized within
this area include the use of containment pallets for materials stored outside the buildings, and
when practical covering of exterior containers used for the collection of recycling materials such
as aluminum drink cans, copper, steel, wood and paper.
SANDBLASTING AND PAINTING AREA
The plant maintains a designated area for sandblasting and painting of large components and
structures. The area also includes a satellite hazardous waste storage area and a recycle
operation for paint thinners. The potential for spills and leaks to release to storm drains or
overland drainage pathways to receiving waters exists, and presents a source for an
unauthorized discharge and contamination of storm water. BMPs utilized include perimeter silt
fencing to retain grit within the sandblast area, and buildings to store the hazardous wastes,
paints and thinners. The blast grit is routinely collected and containerized. Storm water runoff
from this area enters a drainage channel that flows easterly, eventually into the Intake Canal via
outfall SW 013.
VEHICLE AND EQUIPMENT MAINTENANCE
The plant maintains a Garage facility for maintenance of plant vehicles and equipment located
north of the Turbine Building outside of the protected area. Vehicles and equipment have the
potential to leak or spill significant quantities of fuel, hydraulic fluids, and oils if not properly
maintained and operated. Maintenance is performed on a routine basis to keep vehicles and
equipment operational thereby reducing the potential for spills and leaks from mechanical
failure. Some maintenance may be performed offsite at commercial facilities that are subject to
local laws and regulations regarding the disposal of used materials. BMPs utilized include
performing all maintenance inside the Garage, utilizing temporary containment devices for the
capture of fluids, and proper labeling, handling and disposal of used materials, parts and fluids.
BMPs also include readily available spill response materials. Storm water runoff from the
Garage and surrounding area enters a drainage channel that flows easterly, eventually into the
Intake Canal via outfall SW 013.
SECURITY TRAINING AND FIRING RANGE
The plant maintains a designated facility for security training purposes that includes an external
firing range. Lead -based ammunition is routinely fired into earthen embankments at the range.
Storm water runoff from this area flows northerly overland eventually into Nancy's Creek. BMPs
utilized include tracking the amount of ammunition fired into the embankments, routine
monitoring of soil pH levels, and periodic removal and replacement of lead -impacted soils.
BOAT STORAGE AREA
The plant maintains a boat storage area located on the Intake Canal near the Biolab. The boats
contain fuel tanks and are maintained under a shelter. BMPs utilized include maintaining the
boats under the shelter while not in use to prevent direct exposure to rainfall.
15

A list of all currently utilized BMPs within the contributing drainage area for each storm water
outfall is provided on the fact sheets in Appendix B.
2.3 Spill Prevention and Response Procedure
ISW Permit Reference: Part It, Section A, 3
The station maintains Spill Prevention and Response Procedures (SPRP) to control and
minimize contamination of storm water resulting from spills and exposure to materials
associated with facility operations. These procedures incorporate an assessment of potential
pollutant sources based on a materials inventory of the plant. The materials inventory is
primarily compiled and maintained through two efforts; first for development and compliance
with the plant SPCC Plan, and secondly for the management of hazardous materials.
The Brunswick Nuclear Plant is required to develop and maintain an SPCC Plan in accordance
with 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. The SPCC Plan provides an assessment of spill
potential, measures for spill prevention, and a spill response protocol for oil -based liquids. A
similar approach has been adopted for non -oil based liquids and chemicals representing the
balance of materials at the plant. However, the plant will likely maintain the same general spill
response protocol from the SPCC Plan regardless of the types of materials except where
hazardous materials regulations and notifications deviate from SPCC requirements. This is
recognized in the response procedures.
The Site Environmental Coordinator(s) shall maintain a figure depicting locations for all oils,
liquids, chemicals and materials that have the potential to impact storm water. The Site
Environmental Coordinator(s) shall routinely review the SPRP procedures for applicability with
current plant operations and practices, shall amend/update the SPRP as necessary, and shall
communicate changes to responsible plant personnel. Facility personnel responsible for
implementing the SPRP shall be identified in a written list incorporated into the SPRP and
signed and dated by each individual acknowledging their responsibilities for the plan. A
responsible person shall be on -site at all times during facility operations that have increased
potential to contaminate storm water runoff through spills or exposure of materials associated
with facility operations.
Spill Prevention and Response Procedures in -place at the Brunswick Nuclear Plant are listed in
Appendix G.

2.2 Storm Water Management Strategy
2.2.1 Feasibility Study
iSW Permit Reference: Part ll, Section A.2 (a)
This section provides a review of the technical feasibility of changing the methods of operations
and/or storage practices to eliminate or reduce exposure of materials and processes to rainfall
and storm water runoff. Below are descriptions of the existing operations at the plant that
present the potential for negative impacts to storm water runoff. These descriptions
demonstrate the current practices in use to prevent exposure of storage areas, material
handling operations and fueling operations.
DIESEL FUEL AND GASOLINE STORAGE
Diesel fuel is stored at the plant in several different tanks and containers. The diesel fuel is
primarily used as fuel for several emergency diesel generators at various locations at the plant.
The largest diesel fuel containers are the 225,000 gallon capacity Emergency Diesel Generator
7-Day Diesel Fuel Storage Tank, four 23,300 gallon capacity Emergency Diesel Generator
Diesel Fuel 4-Day Tanks, the 10,000 gallon capacity 14-Day Auxiliary Emergency Diesel
Generator Tank, the 2,000 gallon capacity Equipment Fuel Oil Storage Tank, and the 4,000
gallon capacity Emergency Diesel Generator Tank at the EOF/TSC. Gasoline is stored in the
5,000 gallon capacity Equipment Gasoline Storage Tank. A complete listing of these
containers, including inspection and testing requirements, secondary containment descriptions
and inspection requirements, and tanker loading and unloading operation requirements are
described in detail in the Brunswick Nuclear Plant SPCC Plan.
C

All diesel fuel and gasoline storage tanks are provided with some means of passive secondary
containment or are integral double -walled containers. The gasoline tank is an integral double -
walled container. With the exception of the secondary containment for the Emergency Diesel
Generator Tank at the EOF/TSC, all drainages from secondary containments discharge into the
Storm Drain Collection Basin (SDCB). Drainages from the secondary containment for the
Emergency Diesel Generator Tank at the EOF/TSC discharges into the Discharge Canal.
Refueling operations for all diesel fuel containers and the gasoline tank are conducted with
constant attendance in accordance with facility procedures and the facility SPCC Plan. Tanker
trucks are brought on -site to refill the 7-Day Diesel Fuel Storage Tank, the 14-Day Diesel Fuel
Storage Tank, the Equipment Fuel Oil Storage Tank, the Emergency Diesel Generator Tank at
EOF/TSC, and the Equipment Gasoline Storage Tank. Transfer operations are conducted
adjacent to the tanks. Passive secondary containment for tanker unloading at the 7-Day and
14-Day Diesel Fuel Storage Tanks, the Security Emergency Diesel Generator, the Equipment
Fuel Oil Storage Tank, and the Equipment Gasoline Storage Tank is provided by dedicated
curbed concrete unloading platforms. The containment for unloading into the 7-Day Diesel Fuel
Storage Tank discharges into the SDCB. The containment for unloading into the 14-Day Diesel
Fuel Storage Tank is equipped with an open drain and valve that normally directs collected
rainwater to the SDCB, During unloading operations, station personnel change the valve
position to direct any release into an oil collector pit. The containment for unloading into the
Security Emergency Diesel Generator is equipped with a manually operated drain valve that
discharges into SDCB. The containment for unloading into the Equipment Fuel Oil Storage
Tank and the Equipment Gasoline Storage Tank is equipped with a lockable double isolation
ball valve. Drainage from this containment will flow into drainage ditches that direct runoff
easterly and eventually into the Intake Canal.
Smaller bulk storage diesel and gasoline containers and mobile equipment is refilled using the
on -site Mobile Fuel Truck. Tanker unloading operations are conducted adjacent to these
containers. 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 facility
SPCC Plan.
The four 23,300 gallon capacity Emergency Diesel Generator Diesel Fuel 4-Day Tanks are
located inside the Four Day Tank Rooms and are manually refilled by gravity feed via
underground piping from the 7-Day Diesel Fuel Storage Tank. The piping is double -walled
stainless steel. These four Emergency Diesel Generator Diesel Fuel 4-Day Tanks are not
exposed to rainfall or storm water runoff.
There are no changes warranted to reduce the potential for impacts to storm water runoff
associated with diesel fuel and gasoline storage practices or unloading operations at the facility.
All diesel fuel and gasoline containers are in compliance with the facility SPCC Plan.
7

LURE OIL STORAGE
The plant has two large lobe oil storage tanks designated as the 18,000 gallon capacity Turbine
Clean Lube Oil Tank and the 12,000 gallon capacity Turbine Dirty Lube Oil Tank. Both tanks
are located within a 56,000 gallon capacity concrete containment pit equipped with an oil trap
weir that discharges via gravity flow into the SDCB. There is also a 250 gallon capacity used oil
tote equipped with an oil skimmer located adjacent to these tanks that drains into the pit. Water
from the tote can be decanted back into the adjacent pit. There are no changes warranted to
reduce the potential for impacts to storm water runoff associated with these lube oil tanks.
OIL IN USE CONTAINERS AND SYSTEMS
Oil in use 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 in use containers are described in detail in the Brunswick Nuclear Plant SPCC Plan. The
facility contains several lube oil and hydraulic oil reservoirs located inside the various plant
buildings and consequently not exposed to rainfall or storm water runoff. The largest interior oil
in use containers are the two 9,250 gallon capacity Lube Oil Reservoirs located inside the
Turbine Building.
The largest oil in use containers exposed to rainfall or storm water runoff are six 12,930 gallon
capacity Main Transformers, two 10,400 gallon capacity Startup Auxiliary Transformers, two
6,588 gallon capacity Unit Auxiliary Transformers, two 11,840 gallon capacity Caswell Beach
Transformers, and one 12,930 gallon capacity spare Main Transformer. These large
transformers contain mineral oil and are located in the Transformer Yard immediately west of
the Turbine Building within the protected area. All of these transformers are provided secondary
containment by gravel -filled concrete containment pits equipped with oil trap weirs that gravity
drain into the SDCB. There is also one spare 10,400 gallon capacity Startup Auxiliary
Transformer and one spare 6,588 gallon capacity Unit Auxiliary Transformer located in the
northern area of the Switchyard outside of the protected area. These transformers are located
within a single, lined concrete containment basin equipped with an olephilic discharge valve.
The valve freely drains clean rainwater onto the Switchyard, but will close automatically in
contact with oil. There are two 539 gallon capacity SY transformers exposed to rainfall and
storm water runoff located in the Switchyard area west of the Turbine Building. These two SY
transformers are not provided with any means of passive secondary containment. There are
also three replacement transformers that contain approximately 11,000 gallons of oil each,
staged in temporary containments in the northern area of the Switchyard outside the protected
area. The Auxiliary Operators perform inspection rounds of the switchyard each shift. Storm
water runoff from the Switchyard flows overland and eventually into Nancy's Creek via Outfall
008.
There are no changes warranted to reduce the potential for impacts to storm water runoff
associated with the large transformers. The potential for storm water impacts associated with
mineral oil releases from these two SY transformers could be reduced by the installation of
R.

dedicated secondary containments. Covering all electrical equipment in the Switchyard to
prevent direct exposure to rainfall is cost prohibitive.
There are two large transformers and two small circuit breakers located at the Caswell Beach
Discharge Structure. These containers are provided passive secondary containment by a
partially -covered, concrete containment equipped with an oil trap weir that gravity drain into the
Discharge Canal. These containers are not directly exposed to rainfall or storm water runoff.
Smaller oil in use containers exposed to rainfal[ or storm water runoff include numerous pad -
mounted service transformers containing mineral oil and ranging in size from 24 gallons to 667
gallon capacity. These service transformers are located at various locations around the facility.
Four of these pad -mounted transformers are located within the protected area of the plant and
are provided secondary containment by yard drains to the SDCB. Two of these pad -mounted
transformers are provided secondary containment by a French -drain system that discharges
into the SDSF.
None of the remaining pad -mounted transformers are provided with any means of passive
secondary containment. A mineral oil release occurring from four of these transformers would
flow into the Intake Canal. A mineral oil release occurring from the Groundwater Extraction
System Compressor Building service transformer would flow overland eventually entering
Nancy's Creek. A mineral oil release occurring from any of the remaining pad -mounted
transformers would eventually enter the Intake Canal. The facility 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. With
the exception of the service transformer located at the Diversion Structure, 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 could be reduced
by the installation of dedicated secondary containments.
The Diversion Structure service transformer is located on a concrete platform directly over the
intake canal. Consequently, a release occurring from this unit has a high likelihood to directly
impact surface waters. Sized passive secondary containment has been installed for the
Diversion Structure transformer. Work is performed on the Diversion structure five to seven
days per week with the transformer containment being inspected every day workers access the
structure.
CLEAN MATERIAL PROCESSING FACILITY
The Clean Material Processing Facility is the plant waste handling, monitoring and storage area.
The facility is comprised of two buildings and surrounding laydown areas located outside of the
protected area. The first building is a central processing area used for monitoring waste
materials for low level radioactivity prior to leaving the site. A trash compactor is located
E

adjacent to the this building and is used for compacting routine trash generated at the plant.
The second building is used for segregating and processing chemical wastes, hazardous
wastes, waste oil, used fluorescent bulbs, batteries, paints, oily wastes, and other materials for
disposition. The second building is equipped with a curbed concrete floor and dead-end sump
designed to collect and contain any spills within the building.
The laydown/storage areas and areas around the Clean Material Processing Facility are
comprised of approximately 50% paved surfaces and approximately 50% gravel -surfaced areas.
All wastes and chemicals that could potentially impact storm water are maintained inside the
buildings or on exterior containment pallets. The facility has exterior containers used for the
collection of recycling materials such as aluminum drink cans, copper, steel, wood and paper.
No significant materials that could potentially impact storm water are stored in the exterior
laydown areas. A 40 X 50 foot curbed containment with lockable drain valves in located in the
area for storage of mobile equipment. Tractors and mowers are stored in a building adjacent to
this containment. Storm water runoff from this area discharges into Nancy's Creek via Outfall
007. There are no changes warranted to reduce the potential for impacts to storm water runoff
associated with the Clean Material Processing Facility.
SANDBLASTING AND FAINTING AREA
The plant maintains a designated area for sandblasting and painting of large components and
structures. The sandblasting yard is surrounded by a silt fence to prevent sandblast grit from
entering a nearby storm water drainage ditch. Located within this area are buildings used for
painting plant components and equipment, and for storing hazardous waste, paints and
thinners. Storm water runoff from this area enters a drainage channel that flows easterly,
eventually into the Intake Canal via outfall SW 013. The potential for storm water impacts
associated with the sandblasting operation could be reduced by installing curtains around the
sandblast area to prevent drift of the sandblast material, and by improved management and
disposal of the sandblast residuals. Processes are being developed for controlling and
containerizing the blast grit, and for enhancing sediment and erosion control measures.
EXTERNAL STORAGE AND LAYDOWN AREAS
The plant does not maintain extensive external storage areas. Inert materials such as soil,
sand, gravel, compost, concrete, asphalt, metal and wood may be stockpiled at certain locations
on a temporary basis until the material can be recycled, reused or properly disposed of off -site.
Stockpiled material 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. Storm water runoff from these
exterior storage areas either discharges into Nancy's Creek via Outfalls 007 or 009, or into the
Intake Canal. The potential for storm water impacts associated with these external storage
areas could be reduced by covering soil, gravel, treated lumber, flaking painted surfaces and
other materials that represent the greatest potential for such impacts. Constructing permanent
shelters over these external storage and laydown areas is cost prohibitive.
IE

SECURITY TRAINING AND FIRING RANGE
The plant maintains a designated facility for security training purposes that includes an external
firing range. The range is constructed on the top of the former inert debris landfill. Lead -based
ammunition is routinely fired into earthen embankments at the range. Storm water runoff from
this area flows northerly overland eventually into Nancy's Creek. Security personnel maintain an
inventory of expended rounds fired and routinely monitor soil pH levels in the embankments to
determine schedules for lead harvesting of the soil. Constructing permanent shelters over the
embankments to eliminate exposure to rainfall is cost prohibitive.
BOAT STORAGE AREA
The plant maintains a boat storage area located on the Intake Canal near the Biolab. Boats are
stored under shelter. Storm water runoff from this area enters the recovery pond located behind
the Biolab. There are no changes warranted to reduce the potential for impacts to storm water
runoff associated with this area.
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
fSW Permit Reference: Part ff, Section A.2 (,b)
The plant manages numerous oil -based liquids and non -oil based liquids and chemicals which
are critical to power generation and transmission, waste handling and treatment, and operation
of vehicles and equipment used at the facility.
The Brunswick 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
11

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 current list of all liquids and chemicals and their associated secondary containment provisions
is maintained in eTrac and is also provided in Appendix F. Documentation for periodic
inspections for leaks and recordation of accumulated storm water releases are documented in
Appendix 1.
2.2.3 Best Management Practices (BMPs) Summary
IS IN Permit Reference, Part ll, Section A.2 (c)
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.

exterior storage areas and storage buildings, the Meteorological Tower, and
rassed and wooded areas.
Industrial
The Clean Material Processing Facility is comprised of two buildings and
Activities
surrounding laydown areas located outside of the protected area. The first
building is a central processing area used for monitoring waste for the
presence of radioactivity prior to leaving the site. A trash compactor Is located
adjacent to the main building and is used for compacting routine trash
generated at the plant. The second building is used for segregating and
storing chemical wastes, hazardous wastes, waste oil, used fluorescent bulbs,
batteries, paints, oily wastes, etc.
The storage areas contain inert wood and metal materials.
Significant
Clean Material Processing Facility: Waste chemical and oils, solid and
Materials/
hazardous wastes, used fluorescent bulbs, batteries, paints, routine trash.
Potential
Pollutants
Storage areas: miscellaneous wood, structural steel, cable, and other metal.
BMP Summary
Clean Material Processing Facility:
• The buildings are designed with curbed concrete floors and dead end
sumps to contain an liquid spills within the buildings.
• Plant procedures are followed regarding storage, handling and transfer of
all waste materials.
• No waste materials that could impact storm water are stored in exterior
areas.
• Plant personnel are trained in appropriate spill response procedures.
Storage Areas:
• Stored materials that could impact storm water are covered or stored
inside buildings.
• A curbed containment structure with lockable drainage valves is used for
equipment storage.
