Why Industrial Sites with Stormwater are Subject to a Permit: Federal NPDES regulations define
stormwater discharge associated with industrial activity in 40 CFR §122.26 (b)(14) as: "the discharge
from any conveyance that is used for collecting and conveying storm water and that is directly related to
manufacturing,processing or raw materials storage areas at an industrial plant. The term does not
include discharges from facilities or activities excluded from the NPDES program under this part 122.
For the categories of industries identified in this section, the term includes, but is not limited to, storm
water [sic] discharges from industrial plant yards; immediate access roads and rail lines used or traveled
by carriers of raw materials, manufactured products, waste material, or byproducts used or created by
the facility; material handling sites; refuse sites; sites used for the application or disposal of process
waste waters (as defined at part 401 of this chapter); sites used for the storage and maintenance of
material handling equipment; sites used for residual treatment, storage, or disposal; shipping and
Page 2 of 9

receiving areas; manufacturing buildings; storage areas (including tank farms) for raw materials, and
intermediate and final products; and areas where industrial activity has taken place in the past and
significant materials remain and are exposed to storm water. For the purposes of this paragraph, material
handling activities include storage, loading and unloading, transportation, or conveyance of any raw
material, intermediate product, final product, byproduct or waste product. The term excludes areas
located on plant lands separate from the plant's industrial activities, such as office buildings and
accompanying parking lots as long as the drainage from the excluded areas is not mixed with storm
water [sic] drained from the above described areas."

Section 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities and data was
submitted for October 2017 to January 2022. Quantitative sampling included pH, TSS, and O&G.
Page 3 of 9

Parameters are based on potential pollutants in the drainage area, sampling results, and in some cases,
dependent upon future activities (e.g., ash removal through the drainage area). Below is a table of the
proposed monitoring for each outfall at the Brunswick Nuclear Plant site.

Stormwater Benchmarks and Tiered Response: Rather than limits,North Carolina NPDES
Stormwater permits contain benchmark concentrations. Stormwater benchmarks are numerical action
levels for stormwater monitoring. Benchmarks are not effluent limits, and benchmark exceedances are
not permit violations. Benchmarks provide facilities a tool for assessing the significance of pollutants in
stormwater discharges and the effectiveness of best management practices (BMPs). Benchmark
concentrations are intended as guidelines for the facility's development and implementation of the
Stormwater Pollution Prevention Plan(SWPPP).
Benchmark exceedances require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater BMPs in a tiered program. The permit establishes a
tiered approach to specify actions the permittee must take in response to analytical results above
benchmark concentrations. The tiered structure of the permit provides the permittee and DEMLR wide
flexibility to address issues that may arise with one or more parameters and/or outfalls.
Metals benchmarks are calculated to mimic acute water quality standards and with the guidance of
DWR. NC DWR follows established federal procedures for calculating acute standards when developing
the benchmarks. Just like the acute standards, metals benchmarks normally reflect one half of the
calculated Final Acute Value (the "1/2 FAV"). In most cases, translation into total recoverable values is
based on an assumed hardness of 25 mg/L and a total suspended solids (TSS) concentration of 10 mg/L.
Acute standards protect aquatic life from negative impacts of short-term exposure to higher levels of
chemicals where the discharge enters a waterbody. The Stormwater Permitting Program applies this
approach because of the ephemeral nature of rainfall events.
Page 5 of 9

The Division may evaluate results to determine if a smaller suite of parameters for some outfalls is
adequate to characterize potential pollution or BMP effectiveness. For example, one or more metals or
other parameters may serve as an adequate tracer for the presence of ash pollution during disturbance or
ash removal in specific drainage areas at this site. For parameters that do not have a stormwater
benchmark, the Division may develop a benchmark value if appropriate toxicity data become available
or if rising trends in concentrations suggest a persistent source.
A summary of the benchmarks in the draft permit, and their basis, is below:
Parameter Benchmark Basis
Total Suspended Based on '/2 standard benchmark of 100 mg/L
Solids (TSS) 50 mg/L
HQ
H 6.8 s.u. — 8.5 s.u. NC Water Quality Standard(Range)
Non-Polar Oil & Review of other state's daily maximum benchmark
Grease 15 mg/L concentration for this more targeted O&G;NC WQS that
EPA Method 1664 does not allow oil sheen in waters
SGT-HEM
Aluminum Total 240 µg/L '/z FAV
Copper Total 6 /L Acute Aquatic Criterion, '/2 FAV
Chromium Total 1,100 /L '/2 FAV
Lead Total 220 /L '/2 FAV
Nickel Total 74 µg/L '/2 FAV
Zinc Total 95 µg/L '/2 FAV
Stormwater Pollution Prevention Plan: The proposed permit conditions reflect the EPA and NC's
pollution prevention approach to stormwater permitting. The Division's maintains that implementation
of Best Management Practices (BMPs) and traditional stormwater management practices that control the
source of pollutants meets the definition of Best Available Technology(BAT) and Best Conventional
Pollutant Control Technology(BCT). The permit conditions are not numeric effluent limitations but are
designed to be flexible requirements for implementing site-specific plans to minimize and control
pollutants in stormwater discharges associated with the industrial activity. Title 40 Code of Federal
Regulations (CFR) §122.44(k)(2) authorizes the use of BMPs in lieu of numeric effluent limitations in
NPDES permits when the agency finds numeric effluent limitations to be infeasible. The agency may
also impose BMP requirements which are "reasonably necessary" to carry out the purposes of the Act
under the authority of 40 CFR 122.44(k)(3). The conditions proposed in this draft permit are included
under the authority of both of these regulatory provisions. In essence, the pollution prevention and BMP
requirements operate as limitations on effluent discharges that reflect the application of BAT/BCT.
Flexibility in Tier Responses: Tier Two actions provide an opportunity for the permittee to propose an
alternative monitoring plan for approval by the Region:
• Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances,
exercise the option of contacting the DEMLR Regional Engineer as provided below in Tier
Three. The Regional Engineer may direct the response actions on the part of the permittee as
provided in Tier Three, including reduced or additional sampling parameters or frequency.
• If pursuing the alternative above after two consecutive exceedances, the permittee may propose
an alternative monitoring plan for approval by the Regional Engineer.
Page 6 of 9

The permit therefore allows the permittee to petition the Regional Office for monitoring changes sooner
than Tier Three (upon any four benchmark exceedances) and gives guidance on one option to take. For
example, the permittee may request that mercury only be monitored semi-annually under the tiers, or
that only parameters over the benchmark be monitored more frequently. In this way, changes to the
monitoring scheme for any outfall could be handled outside of a permit modification.
Other Proposed Requirements:
• It is standard for Stormwater Pollution Prevention Plan(SWPPP)requirements to include an
annual certification that stormwater outfalls have been evaluated for the presence of non-
stormwater discharges, and if any are identified, how those discharges are permitted or otherwise
authorized.
• Requirement to submit a request for permit modification if the facility identifies or creates any
new outfalls, removes outfalls, or alters any drainage area that changes potential pollutants.
• The Division expects the permittee to apply best professional judgment and consider the safety
of its personnel in fulfilling sampling obligations under the permit.
• Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). If a
state does not establish a system to receive such submittals, then permittees must submit DMRs
electronically to the EPA.
• Quarterly QualitativeNisual Monitoring to assure regular observation of outfalis throughout
year.
Section 4. Changes from previous permit to draft:
• Monitoring increased from semi-annually to quarterly for all parameters (qualitative and
quantitative)
• "No discharge" clarifications made
• eDMR requirement added
• Feasibility study requirement removed per updated stormwater program requirements
• Boilerplate language moved into body of the permit; boilerplate no longer attached
• Benchmarks updated for parameters per guidance from DWR Standards group on stormwater
benchmarks
• Monitoring for SWO08 separated from SWO07 and SWO09 as monitoring requirements have
been updated
• Monitoring added for BOD, COD, total aluminum, total copper, total chromium, total lead, total
nickel, total zinc, and total hardness for outfalls SWO07 and SWO09
Section 5. Changes from draft to final:
• None
Section 6. Discussions with the Facility and Regional Office:
• Initial contact with facility: 10/5/2022
• Initial contact with Regional Office: 10/4/2022
Page 7 of 9

• Draft sent to CO peer review: 12/15/2022
• Draft sent to Regional Office: 4/6/2023
• Final permit sent for supervisor signature: 5/17/2023
Section 7. Comments received on draft permit:
• Maria Dunn (NCWRC; via email 4/20/2023): NCWRC staff have reviewed the stormwater
permit for the Brunswick Steam Electric Plant. We have no additional comments regarding T/E
species or other matters under the purview of the NCWRC at this time.
• Don Safrit(Duke Energy; via email 5/1/2023):
o Remove "SE" at the beginning of the city/town location on permit cover sheet.
■ DEMLR Response: This change will be made.
o Part C-1 Visual Inspections: Within (a), there is reference to each SDO (unless ROS is
obtained)be subject to visual monitoring/inspections. Do these quarterly visual
monitoring/inspections apply to Stormwater Outfalls SW013, SW014, SW015, SW016,
and SW017 or only the ones associated with industrial stormwater discharge points with
analytical monitoring requirements (SW007, SW008, and SW009)?
■ DEMLR Response: Qualitative monitoring is only required of outfalls permitted
by the stormwater permit, which are Outfalls SW007, SW008, and SW009. If
conditions were to change for Outfalls SW013, SW014, SW015, SW016, and
SW017 to where they would no longer be covered under the wastewater permit,
then a permit modification would be needed to obtain qualitative and quantitative
monitoring.
o Part D Table 1 —Outfalls SW007 & SW009: For the heavy metal parameters (Al, Cu, Cr,
Pb,Ni & Zn), could you provide a little more explanation as to how the specific
benchmarks were established for these parameters?We see in the fact sheet (page 6 of 8)
that for most of the parameters, the basis is 1/2 FAV (except for Cu where there is also
reference to the acute aquatic criterion). Similarly for TSS and pH. Could you cite the
water quality regulatory, surface water classifications or procedural aspects to help us
understand how the specific benchmark values were derived?
■ DEMLR Response: Stormwater benchmarks for all parameters are developed in
coordination with the DWR Standards and Classifications group and based on the
surface water quality standards. More information on the benchmark development
for each requested parameter can be found below:
• Total Aluminum: 1/2 FAV (Final Acute Value); EPA's National
Recommended Water Quality Criteria(Acute) for aluminum.
• Total Copper: 1/2 FAV; EPA's National Recommended Water Quality
Criteria(Acute) for dissolved copper, calculated with assumed 25 mg/L
hardness, and then converted to total with EPA partition translator based

assumed 25 mg/L hardness, and then converted to total with EPA partition
translator based on assumed 10 mg/L TSS.
• Lead: 1/2 FAV; EPA's National Recommended Water Quality Criteria
(Acute) for dissolved lead, calculated with assumed 25 mg/L hardness,

Good morning,
I am working on renewing the individual stormwater permit for the Brunswick Nuclear Plant(NCS000590). I
need additional information in order to 1) confirm that the information I have is correct and 2) make sure the
permit adequately serves the needs of the facility. Please provide the following:
• The site map identifies additional stormwater outfalls not in the permit or renewal application. Please
provide more information on SW013, SW014, SW015, SW016, and SW017;
• Provide more information regarding the storm drain collection basin;
2

• Provide more information on oil used to fuel auxiliary boilers. The 2016 permit application noted
potential pollutants of concern, also checked the "No"box for not present;
• An electronic spreadsheet summarizing all of the monitoring data that has been collected since the
effective date of the current permit;
• Verification that the information in the renewal application is still complete and correct; and
• An explanation of any operational changes since the renewal application was submitted.
Enter your stormwater permit number into the Stormwater Permit Summary Report and you will see a form that
includes the address of the facility, contact information for the permit, and the regulated stormwater outfall(s)
for the facility. Please review the facility information to make sure it is correct. Information can be updated using the
links provided below,where applicable:
• Facility/Company name or ownership: Name/Ownership Change. Form
• Owner Affiliation (Legally responsible person; i.e., someone with the company who is designated to
represent the company per signatory requirements or another authorized representative): Permit Contact

• Delegation of Signature Authority (DOSA): Permit Contact Update Request Form
• Billing contact: Permit Contact Update Request Form
• Permit contact: Permit Contact Update Request Form
• Facility contact: Permit Contact Update Request Form
• Facility address only: Email Bethany og ulias
• Stormwater outfall information: Email Bethany Georgoulias
• Visit the eDMR Six Steps website and complete Steps 1 and 2.
• Pay outstanding permit fees: Stormwater ePgMent website
Once I have the above listed information, I can continue my review. You will receive a draft permit for a 30-day
comment period. During this time we will be able to address any comments or concerns you have. During the
same 30-day period, the draft will be sent to a Regional Office staff member for review as well as out to public
notice. Once all comments and concerns are addressed, you may be issued a final permit.
Please contact me if you have any questions.

Storm Drain Collection Basin Description
(4 pages including cover)

Storm Drain Collector Basin (SDCB) Description
There is an arrangement of drainage piping onsite below grade level which collects and routes
plant runoff and system inputs to the Storm Drain Collector Basin (SDCB)which is located
within the Protected Area of the plant (See Figure 1 —SDCB Site Location). Drainage collection
consists of concrete and cast iron piping of various sizes which receive input from non-
contaminated building floor drains, building roof drains and the Reactor Building Seismic
Isolation Spaces (Rattle Spaces) drainage piping. Plant system inputs to the SDCB include
drainage from the Auxiliary Steam System (Auxiliary Boiler), Makeup Water Treatment System,
and blowdown from the Turbine Building HVAC Cooling Towers.
Water enters the SDCB via the south header input, the north header input, and by a blowdown
line from the Turbine Building HVAC Cooling Towers which discharges into the main basin (See
Figure 2 —Storm Drain Collector Basin (SDCB) Inputs). The main basin is equipped with an oil
skimmer which serves as a retention reservoir for the removal of oil. The oil skimmer consists
of a rotating flexible tube attached to a hollow boom which removes floating oil. The oil adheres
to the surface of the tube and is removed by a scraper attached to the top of the boom. The
removed oil flows down the hollow boom, through the boom pedestal, and into a 250 gallon tote.
The tote is emptied or changed out by plant personnel as needed. The tote sits on a raised
concrete pedestal directly adjacent to the main basin. The tote pedestal is sloped toward the
basin so that that if a leak were to occur the contents of the tote would drain back into the basin
to prevent a spill to the ground. All collected waste materials are properly disposed. The water
in the main basin is directed through the under baffle wall into the pump bay. The baffle has an
8'x 2' opening between the bottom of the basin and the retaining baffle wall of the pump bay.
Any residual oil that may be present in the main basin is maintained above the baffle opening;
therefore, oil cannot pass under the baffle wall into the pump bay. Once drainage has collected
in the pump bay, three centrifugal pumps are provided to empty the contents of the basin into
the Storm Drain Stabilization Facility (SDSF; Outfall 011 NPDES Permit No. NC0007064). The
SDCB is also equipped with two in-line overflow valves. One valve is the overflow isolation
valve and the other is the overflow control valve. During periods of severe inclement weather,
these valves may be opened to prevent water from backing up in the storm drainage header
piping. To be opened, conditions must be severe enough to result in potential personnel safety
concerns or plant equipment damage. During these conditions, these valves would direct the
overflow to the discharge canal (Outfall 001 NPDES Permit No. NC0007064) as opposed to the
SDSF. The diversion valves are operated electrically and controlled by keylock control switches
that are located in the Unit 1 Turbine Building. Discharge from the SDCB is monitored and
integrated by a flow element, flow totalizer, and flow recorder. The flow instrumentation monitors
and displays instantaneous flow rate in gallons per minute and cumulative total volume
discharged (See Figure 3 —Overall Storm Drain Collector Basin (SDCB) Compartments).

Fuel Sources and Information Regarding the Auxiliary Boilers
(2 pages including cover)

Auxiliary Boiler Fuel Supply Description
The fuel source for the Auxiliary Steam (Auxiliary Boiler) System is No. 2 fuel oil which is
supplied from the Main Fuel Oil Storage Tank (See Figure 1 - Fuel Oil Storage and Auxiliary
Boiler System). The Main Fuel Oil Storage Tank is also commonly referred to as the 7-Day Fuel
Oil Storage Tank. The 225,000 gallon tank, in conjunction with the four individual diesel 4-Day
Tanks, is designed to hold a seven day inventory of fuel for the four Emergency Diesel Engines
This tank is located on the North side of the Auxiliary Boiler Building in a bermed area equipped
with drainage. The bermed drain is routed via a catch basin which is equipped with an isolation
valve to prevent fuel oil from being admitted to storm drainage piping. Auxiliary Operators
ensure that oil is not present in any collected water prior to opening the catch basin drain. The
Main Fuel Oil Storage Tank is filled from tanker trucks at the tanker offload skid via manually
operated fuel oil unloading pumps. Fuel Oil for the Main Fuel Oil Storage Tank is procured in
accordance with Duke Energy procedural document NGD-G-0001, Common Diesel Fuel Oil
(Grade 2-D) Specification (See Attachment 1 — Common Diesel Fuel Oil Specification). The
objectives of the procedure are to assure that new diesel fuel oil is of proper quality for use with
emergency power generating systems (i.e., emergency diesel generators and standby
shutdown diesel generators). This is accomplished by establishing a sampling and testing
program for new fuel oil, along with appropriate acceptance criteria, in accordance with
applicable ASTM standards. Specifically, this program assures that new fuel oil is of
appropriate grade and has not been contaminated with substances that could have an
immediate, detrimental impact on diesel engine combustion. Typically, new fuel oil is procured
from the Paw Creek Terminal in Charlotte, NC. Fuel is picked up at the terminal via use of a
nuclear dedicated tanker truck and transported to the Duke Energy Analytical Lab (DEAL) in
Huntersville, NC where it is sampled to ensure compliance with Duke Energy procedures as
discussed above. After sampling, the tanker is then transported to the site for offload. A final
Certificate of Laboratory Analysis report is generated once all analyses have been completed.

1.0 SCOPE
This specification applies to the use of Grade 2-D diesel fuel with up to 5.49% (B5)
biodiesel for the Duke Energy Nuclear Generating Stations.
The objective of the Common Diesel Fuel Oil specification is to assure that new diesel fuel
oil is of proper quality for use with emergency power generating systems (i.e., emergency
diesel generators and standby shutdown diesel generators). This is accomplished by
establishing a sampling and testing program for new fuel oil, along with appropriate
acceptance criteria, in accordance with applicable ASTM standards. Specifically, this
program assures that new fuel oil is of appropriate grade and has not been contaminated
with substances that could have an immediate, detrimental impact on diesel engine
combustion.
This specification addresses analytical testing of new fuel oil. The specification does not
address other aspects of diesel fuel oil management, such as storage tank inventory,
storage tank water removal, etc. CSD-CP-ALL-6011, Guidelines for Diesel Fuel Oil
Programs provides the guidance for the Diesel Fuel Oil Programs.

Note: If any of the Acceptance Criteria are not met, the new fuel oil shipment shall be rejected, with the
following exceptions:
If the new fuel oil fails the Clear and Bright visual appearance test, the sites have the option to
test for Water and Sediment, in order to accept the new fuel oil shipment.
If the new fuel fails the Biodiesel Content test (>5.49%), the fuel may be used only during an

actual design basis emergency involving extended operation of the emergency diesels after
reasonable attempts to procure ULSD Grade 2-D diesel fuel have been exhausted. The
Biodiesel Content test is not a Technical Specification or Selected Commitment Requirement.
Once new fuel oil has been verified to meet the Acceptance Criteria, it may be off-loaded to the
appropriate storage tank. An approved fuel oil additive and biocide should be added to the new fuel oil.
The following fuel oil additives and biocide are currently approved for use at Duke Energy Nuclear
Stations:
Fuel Oil Additive - FOA-15 (normal dosage is 238 - 242 mL per 1,000 gallons of fuel oil)
FOA-35A (normal dosage is 313 - 317 mL per 1,000 gallons of fuel oil)
PRI-D (normal dosage is 1887 - 1897 mL per 1,000 gallons fuel oil OR 1 gallon per 2,000 gallons fuel
oil)
Biocide - U.S. Borax Biobor JF (normal dosage is 418 -422 mL per 1,000 gallons fuel oil)
NOTE: Biobor JIF acts as a biocide and a lubricity additive.
Conductivity does not apply to retail level deliveries where flammable vapors are usually
absent. Conductivity applies more to filling tank trucks, barges, ship compartments and rail
cares where flammable vapors from past cargo can be present.(D975-1 8 Conductivity)
In addition to the Acceptance Criteria, additional testing of new fuel oil is required within 31
days to verify that other applicable properties are met. The same sample taken to test for the
Acceptance Criteria, or a second sample taken at the same time as the sample for the
Acceptance Criteria, shall be used for this additional testing.

1. Determination of Saybolt Universal Viscosity shall be by conversion from Kinematic Viscosity utilizing ASTM
D 2161, rather than direct measurement.
2. If the Cetane Index is used in place of Cetane Number and does not meet the acceptance criteria,then a sample
of fuel oil shall be tested in accordance with either ASTM D 6890 or ASTM D 613 to determine Cetane Number.
ASTM D 613 is the referee method for Cetane Number.
3. If Low Sulfur Grade No. 2-D S500 or Ultra-low Sulfur Grade No. 2-D S15 fuel oil is specified, either the Cetane
Index or Aromaticity requirements must be met.ASTM D 975 specifically requires the use of test method D 976
as the method to test for Cetane Index to determine aromaticity.
4. Cetane Number value for H.B. Robinson is based on the site approved Cetane Index value of45 with the design
margin (±3) removed.
5. High Heating Value test is a tech spec requirement for BNP; however, it will be performed as a pre-offload test
for RNP, BNP and HNP. For all other sites it shall be performed as a post-offload test. See Attachment 5 for
specific conversion instructions. Both the HHV in BTU/Ib and BTU/gallon results shall be reported.
6. API Gravity is a measure of density not heat content,therefore, is not a good indicator for fuel that contains biodiesel. If
biodiesel is present in the tanker, gross heat of combustion is a more accurate measurement than calculated heat
content from API Gravity. API Gravity is a Tech Spec. requirement for most sites and is the governing limit. A truck
should not be accepted if it meets Heat of Combustion and fails API Gravity.
7. Failure of a sample to meet the cloud point acceptance criteria specified shall not be cause for rejection. The non-
conformance shall be entered in the corrective action program with the appropriate compensatory actions taken in
accordance with OP-925, Cold Weather Operation. In no case shall fuel oil be accepted with a cloud point in excess of
230F unless directed by a SRO during a declared Unusual Event or higher emergency.
8. Individual deliveries of fuel oil with a high heating value as low as 136,400 BTU/gal may be accepted provided the
resultant high heating value when averaged with an equal volume of storage tank fuel is no less than 137,000 BTU/gal.

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.
6

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
8

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 rainfall 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
9

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.
10

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

Description Processing Facility buildings and surrounding laydown areas, miscellaneous
exterior storage areas and storage buildings, the Meteorological Tower, and
grassed 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.
