Subject: RE: McGuire Landfill
Melanie,
The best approach is to apply for this general permit and it will be specified in your permit that in case of no flow, just
record no discharge. This will cover you and matter of fact it will be more record keeping. Please let me know if you have
any other questions. Thanks

Subject: McGuire Landfill
Hello Zahid! We did some calculations and it looks like only one of the sediment basins is sized for the 25 year event.
Since the entire area associated with the landfill activity drains to the leachate pond, I guess we are still required to have
the general permit? If we do apply for this permit, how do we handle the fact that there will be no discharge? Do we just
document "no discharge" after each sampling event?
Thanks!
Melanie

Hello Zahid — I just left you a voicemail regarding this email. We are trying to determine if there are any stormwater
permitting needs for our McGuire Nuclear landfill. A site visit would probably be helpful — please let me know your
availability.
Please call my cell as I am in the field a lot this week.
Thanks so much!

Subject: McGuire Landfill question
Hello James! I left you a voicemail but wanted to follow up with some details. We are trying to determine if our landfill
at McGuire Nuclear needs a post -construction stormwater permit. The drainage from the open cell goes to a leachate
pond, which is pumped to our waste treatment system before being discharged. The entire open cell is in a depressed
area and is quite small (<< 1 acre). The cell is surrounded by a grassed embankment, the drainage from which largely
infiltrates or flows to 3 sediment basins. These sediment basins NEVER discharge, even in major storm events. They
typically have little to no standing water in them.
We are trying to figure out if we are required to have coverage under NCG120000, how would we grab samples since
there are no actual outfalls?
I also have a question about a "mud" pit that is adjacent to the landfill area. We place mud and dirt in this area that is
sometimes used as fill or cover dirt at substations. It is quite small and they use hay bales to contain it. When necessary,
it is drained to the sediment basin just downslope. Below the sediment basin there are wetland areas. Are we required
to have a permit for this area? Please let me know if you think we need a site visit to discuss. You can reach me on my
cell (see number below) any time.
Thanks!

SECTION A: STORNIWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
Site Plan. The site plan shall provide a description of the,physical facility and the
potential pollutant sources which may be expected to'. contribute to contamination of
stormwater discharges. The site plan shall contain the.following:
(a) A general location map (USGS quadrangle map or 'appropriately drafted
equivalent map), showing the facility's locationjn relation to transportation routes
and surface waters, the name of the receiving water(s) to which the stormwater
outfall(s) discharges, or if the discharge is\to a municipal separate storm sewer
system, the name of the municipality and the ultimate receiving waters, and
accurate latitude and longitude of the" ' int(s) of discharge. The general location
map (or alternatively the'site map) shall identify whether each receiving water is
impaired (on the sta'tc's,303(d),Iist of impaired waters) or is located in a
watershed for which'a.TNIDL has been established, and what the parameter(s)
of concern are.,
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants which
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn to scale (including a distance legend) showing: the site property
boundary, the stormwater discharge outfalls, all on -site and adjacent surface
waters and wetlands, industrial activity areas (including storage of materials,
disposal areas, process areas, loading and unloading areas, and haul roads), site
topography, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each
drainage area, buildings, existing BMPs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the three (3) previous years and any corrective actions taken to mitigate
spill impaCts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part III, Standard Conditions, Section
Part 11 Page 1 of 10

Permit No, NCS000020
B, Paragraph 5. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. Inareaswhere elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas ofpotential contamination.
(b) Secondary Containment Requiremenis'and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section
313 of Title H1 of the Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and'`stoeage in any amount of hazardous substances, in
order to prevent leaks and spills from contaminating stormwater runoff. A table
or summary of all such tanks and stored materials and their associated secondary
containment areas shall be.maintained. If the secondary containment devices are
connected to stormwater conveyance systems, the connection shall be controlled
by manually activated valves or other similar devices (which shall be secured
closed with a;locking:nechanism), and any stormwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
signilicant. quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) responsible for implementing the
SPRP shall be identified in a written list incorporated into the SPRP and signed and dated
by each individual acknowledging their responsibilities for the plan. A responsible

person shall be on -site at all times during facility operations that have the potential to
contaminate stormwater runoff through spills or exposure of materials associated with the
facility operations. The SPRP must be site stormwater specific. Therefore, an oil Spill
Prevention Control and Countermeasure plan (SPCC) may be a component of the SPRP,
but may not be sufficient to completely address the stormwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference into the
SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program shall be developed. The program shall list
all stormwater control systems, stormwater discharge outfalls, all on -site and adjacent
surface waters and wetlands, industrial activity areas (including material storage areas,
material handling areas, disposal areas, process areas, loading and unloading areas, and
haul roads), all drainage features and structures,'and existing structural BMPs. The
program shall establish schedules of inspections, maintenance, and housekeeping
activities of stormwater control systems, as well`as,facility equipment, facility areas, and
facility systems that present a potential for stoiniwaier,exposure or stormwater pollution.
Inspection of material handling areas and.reg6lar cleaning schedules of these areas shall
be incorporated into the program. Timely compliance with the established schedules for
inspections, maintenance, and housekeeping shall be recorded in writing and maintained
in the SPPP. I
5. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill response
and cleanup, preventative maintenance activities, and for any of the facility's operations
that have the potential to contarinate stormwater runoff. Facility personnel (or team)
responsible for implementing` the training shall be identified, and their annual training
shall be documented by the -signature of each employee trained.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the
Stortwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stormwater orrtfal is have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management Plan.
The Director may notify the permittee when the Plan does not rneet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall

submit a time schedule to the Director for modifying the Plan to meet minimum
requirements" The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions. Section B. Paragraph 5) to the Director that the changes
have been made.
$. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as
part of the Preventative Maintenance and Good Housekeeping Program at a minimum on
a semi-annual schedule, once during the first half of the year (January to June), and once
during the second half (July to December), with at least 66 days separating inspection
dates (unless performed more frequently than semi-annually). These facility inspections
are different from, and in addition to, the stormwater discharge characteristic monitoring
required in Part 11 B and C of this permit.
9. Implementation. The permittee shall implement the Plan., Implementation of the Plan
shall include documentation of all monitoring, measurements,- inspections, maintenance
activities, and training provided to employees; including the log of the sampling data and

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall. The time
between this storm event and the previous storm event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a discharge be, -,ins within 10 hours.

Enclosed with this letter is a copy of the draft stornnvater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
Analytical monitoring changes:_
I. Analytical monitoring parameters have been added to this permit.
2. pl-1 has been added to the analytical monitoring requirements.
3. All analytical monitoring has been set to semi-annually during a representative storm event as defined in
['art II Section 13. The pernlittee nulst also c}ocunlent the total precipitation for each event. If no discharge
occurs during the sampling period, the pCIAllltte{'_ I11LISt Submit a monitoring report indicating "No Flow-"
within 30 days of the end of the six-month sampling period. Additionally, samples must be taken a
mininluill of 60 days apart, as specified in Table 2.
4. Benchmarks for analytical monitoring; have been added to this draft permit. FXCeedarlCC% of benchmark
values require the permittee to increase monitoring, increase management actions, increase record
keeping, and/or install stornlwater Best Management Practices ([3M1's) in a tiered program. If the
sampling results are above a benchmark value, or outside of the benchmark range, for any parameter at
any outfall then the facility shall follow the Tier 1 guidelines which require a facility inspection within
two weeks and implementation of a mitigation plan within two months. If ciurillg the terns of this permit,
the sampling results are above the benchmark values, or outside of the benchmark range, for any specific
parameter ata specific discharge outfall two tirlleq in it row (consecutive), Ihen the facility shall follow the
Tier 2 guidelines which require a repetition of the steps listed for Tier'l and also immediately institute
montli[v monitoring for all parameters at every outfall where a sampling result exceeded the benchmark
value for two consecutive samples.
5. You are required to collect all of the analytical and qualitative monitoring; samples during representative
storm events as defined in Part II Section 13. Qualitative monitoring is required regardless of
representative outfall status.
6. You are responsible for all monitoring until the renewal permit is issued. See Footnote "1 of `I"abler "I, 4,
and 3.

7. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is in this permit, however.)
S. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical
and qualitative monitoring. Monitoring for TPI-I has replaced Oil & Grease. This requirement appears in
all Individual Stormwater permits, however it only applies to facilities that do vehicle maintenance. If tite
facility begins vehicle maintenance during the permitted timeframe then the requirements shall apply.
Other permit changes:
-1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants
in each outfall. `Che map requirements are stated more explicitly. And, the site plan must contain a list of
significant spills that have occurred in the past three years and also must certify that the outfalls have
been inspected to ensure that they do not contain non-stormwater discharges. Additional information is
provided in Part 11 Section A.
?. Additional requirements for the Storrmvater Management Plan have been specified in Part II Section A.
More details regarding secondary containment are provided.
3. Additional requirements for the Stormvvater Pollution Prevention Plan have been specified in Part II
Section A. The plan musL alsu be updated annually to include a list of significant spills and to certify that
the outfalls do not contain non -storm water discharges.
4. 'File facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A,
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial
materials and activities are notexposed to precipitation or runoff as described in 40 CFR §122.26(g), the
facility may qualify for a No Exposure Exclusion from NPDES storrnwater discharge permit
requirements. Additional information is provided in Part I Section A.
6. Per the requirements of the Catawba Riparian Buffer Rule, all stormwater drainage from portioils; of
this site that have been constructed after June 30, 2001 must be discharged through a correctly
designed level spreader or another device that meets diffuse flow requirements per 15A NCAC 213
.0243. Diffuse flow requirements are described in Chapter 8 of the North Carolina Stormwater BMP
Manual, available at: littp://portal.ncdeiir.org/web/wq/ws/su/bmp-manual.
7. In addition to submitting two signed.copies of DMRs to Central Files, a separate signed Annual Summary
DMR copy must be subatitted to the local lAVQ Regional Office by March 1 of each year.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Conments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.

Part it Page 2 of 10

Permit No. NCS000020
person shall be on -site at all times during facility operations that have the potential to
contaminate stonnwater runoff through spills or exposure of materials associated with the
facility operations. The SPRP must be site stormwater specific. Therefore, an oil Spill
Prevention Control and Countermeasure plan (SPCC) may be a component of the SPRP,
but may not be sufficient to completely address the stonnwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference into the
SPRP,
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping, program shall be developed. The program shall list
all stonnwater control systems, stonnwater discharge outfalls, all on -site and adjacent
surface waters and wetlands, industrial activity areas (including material storage areas,

program shall establish schedules of inspections, maintenance, and housekeeping
activities of stormwater control systems, as well as facilityecluipment, facility areas, and
facility systems that present a potential for stormwater exposure or stonnwater pollution.
Inspection of material handling areas and regular cleaning schedules of these areas shall
be incorporated into the program. Timely compliance with the established schedules for
inspections, maintenance, and housekeeping- shall be recorded in writing and maintained
in the SPPP.
5. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill response
and cleanup, preventative maintenance activities, and for any of the facility's operations

desigm, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stonnwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management Plan.

Revised Permit Recommendations: Analytical 'Monitoring:
1. Because the data they have submitted from their site have exceeded our current benchmarks, the same
parameters have been kept in Duke's permit as its previous permit cycle.
a. I have added BOD and COI) to the permit in SWO04 to capture any other unknown organ iclinorganic
compounds — I am especially concerned about areas near and around the hazardous waste storage area.
If outfalls are be re-evaluated, BOD & COD must be pleasured at appropriate outfalls.
b. PCBs have been kept in the permit as they have had a significant PCB reading from outfall 006 and as
these are extremely toxic/hazardous substances — both to human and aquatic life,, Additionally, there are
transformers located all over the property. Instead of a benchmark numb6r,of zero, the wording "There
shall be no discharge of polychlorinated biphenyl compounds" and ` he permittee shall report results
either as "Non -Detect" (include the reporting level), or as the result, in pg/l ;Any detection above the
reporting level shall be deemed to be above the benchmark" was added to the permit. After consulting
'F
with classifications and standards (Connie Brower) and NPDES'WWjSergei C.hernikov) it was decided
that this wording was clearer than using the benchmark of "0"-, as the current techniques. cannot actually
test to 0. Quantitation limits (PQLs) of PCBs (usuall.y;at or near I pg/L) are much highdi than aquatic
life standards (1 ng/L). Additionally, PQLs will change daily within and between labs." These factors
make it difficult to write the action level as a num6ric benchmark. -Therefore SPU has chosen to write
the benchmark in this manner so that any detection over the,PQL_is an exceedence of the benchmark.
This method will also incorporate advances in methods of -PCB `detection levels. This is also more
consistent with NPDES WW's wording.,
c. TPH is recommended because of USTs in outfall 008, Flaz waste and°oil storage in outfall 004, and oil
filled transformers all over the prop&fy�(including outfall 006).
d, pl-I has been kept in the analytical monitoring -requirements.
2. All analytical monitoring has been set to semi-annually' during a representative storm event as defined in Part II
Section B. The permittee must also documenvthe total precipitation,forreach event. If no discharge occurs
during the sampling period, the permittee must subiriit:a monitoring report indicating "No Flow" within 30 clays
of the end of the six-month sampling period. Additionally, samples must be taken a minimum of 60 days apart,
as specified in Table 2. • w a Ci + "+_41''a
3. Benchmarks for analyticafrnonitori�g,.have been added`t&this draft pert -nit. Exceedances of benchmark values
require the permittee.to increase monitoring, increase management actions, increase record keeping, and/or
install stormwater Best Management practices (BMPs) in a tiered program. If the sampling results are above a
benchmark value, or outside of, the benchmark"range, for any parameter at any outfall then the facility shall
follow the.Tier--.1 guidelines -which require a facility inspection within two weeks and implementation of a
mitigation plan wrthin two`rriofths,,If during the term of this permit, the sampling results are above the
benchmark values, or outside of the';henchtiiark range, for any specific parameter at a specific discharge outfall
two times -in a row (consecutive), th'Wthe facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for TierKI and'also immediately institute monthly monitoring for all parameters at every outfall
t
where a"sampling result exceeded the benchmark value for two consecutive samples.
4. The permitt6e'is required{to collect all of the analytical and qualitative monitoring samples during representative
storm events as, fined in Part It Section B. Qualitative monitoring is required regardless of representative
outfall status.
5. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tahles 1, 4,
and 5.
6. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
7. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
Page 7 of 15

NCS000020
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And. the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part lI Section
A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part 1I Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the stormwater Pollution Prevention Plan have been specified in Part lI Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do not
contain non-stormwater discharges.
H.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A. t=
5. Information regarding the No Exposure Exclusion has been added to this,'draft permit. If industrial materials and
activities are not exposed to precipitation or runoff as described in 40 CFR.§ 122.26(g)`,;the, facility may qualify
for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. `Additional information
is provided in Part I Section A. ,

Discussions with permittee: Eric Schook, EH&S, 704-875-4150, E ASHook@duke-ener w.corii.."Called 7/23/10
- left message for Eric Schook. Called August 3, 2010, left message.,Sent eniail 8/3/10 requesting; he contact me
by August 17, 2010. He does not work there anymore and has lefila',rimessage,with John Williamson: 980-875-
5894. Received email with reply from J. Williamson on Friday August 6;'2010. Spoke to him on Tuesday. August
xw 10, 2010. My additional questions and his answers on 8/10/2010 areritten in blue.
1. Q: Has anything changed significantly (industr'ial process or otherwise) since your'last permit renewal?
a. ANSWER: No. We have added several buildings,but all the processes are contained within the
buildings. The Outsourced Water Treatinent Building housed a lot of bulk chemicals for water
treatment (purification for plant writer n�twaste w6te+r): Any spillage from this building; would
go to a sump in the building; that is discharged to our,waste water treatment system. If a spill
occurred during chemical delivery outside of the building, the spillage would go to a large paved
area and if lar&-'enough'Tto the WWCB (Warty Water Collection Basin) Outfall 0051 SW 001.
2. Your WW permit was'renewed in 2006 — have they contacted you about renewal yet? When is it scheduled to be
41
.I,IAi
renewed?
a. Our. Waste Wateeperinit has beekrene,ived as of 4-01-2010
3. 1 have here -that your -receiving stream Js.the Catawba River — is that correct?
'a..'
-,Correct `
1b ItJ 4 •
4. Are you' aware�of the Catawba River Buffer Rules? Are you planning any building?
r 'crt.,
a. We'are'subject to Mecklenburg; County and the City of Huntersville water shed restrictions. We have
3 consir`tiction,pi-ojects pending right now. One has an active Erosion Control plan associated with
it. The'-6ther:2 construction projects are rather small and are under the l acre surface area
requirements for an erosion control plan. All building projects and land disturbing; activities on -site
require the use of BMPs for Storm Water control.
5. Why did you do analytical sampling on different dates?
a. I have not looked at the data. I will have to check.
JW to .IJ: The sampler went off on the wrong; day — it started to go off but then stopped so they had
to take it another day. They have 3 automatic samplers at sampling sites.
Page 8 of 15

NCS000020
We purchased new samplers in 2007 or 2008. We now have 3 dedicated samplers for McGuire. We
previously shared samplers with the rest of the Carolina's plants
G. Do you have any other chemicals or materials that are outside that might be exposed to stormwater such as?
a. Oils?
b. Bulk chemicals?
c. Totes?
A
d. Loading and unloading areas? What chemicals?`
r ,a
e. Other? A
c �a
All are listed in the Supplemental Information document submitted'witli the`permit.renewal package.
7. Are you discharging any cooling water or cooling water chemicals,to.stormwater outfalls?.:";':
a. If by cooling water you mean once through cooling`water the answer is no.
8. Do you have any floor drains that drain to stormwater outfalls?';
a. No Floor drains go to our waste water treatment sy`stern or our domestic sewage system which goes
to CNIUD (Charlotte Mecklenburg Utilities Departmeni)' t%
outfall 001:
9. Outfall 001 — is that still permitted as outfal1005-under the WW permit? What are you testing for there?
a. That is correct. We have limits for TSS, Oil afid`Grease,-pH and Chronic Toxicity on our WW
Outfall 005.
Outfall002: _
10. Why is groundwater monitored iii'the' area of outfall'002?,Do you have a groundwater permit?
a. We monitor for radioactivetconstituents at`several monitoring wells near outfall 002. They are
part of our Ground�Wate� Protection Program for radiological constituents. We have permits
for the ground water,,-vells with`iVlecklenburg County.
1 l . What are, the cyelone separatdrs,insoutfa4i_002? Are they industrial?
a: They are forour blow L,evel,Intake at the bottom of Cowan's Ford 1)am. The separators are to
remove silt from4he water:: -The water is raw lake water. I would consider them industrial
,-.activity. They are,contained in a building.
12. What are the low level intake pumps and low-level storage? Are they industrial?
r
a. The Low, Level Intake draws cold water from the bottom of the lake at the bottom of Cowan's
' e
Ford Dam.- he he water is mixed with our surface water intake water in the summer to help us
achieve compliance with our monthly discharge temperature limit in the summer. I would also
consider these to be industrial activity.
13, There appears to be some erosion (Re: MRO site visit in 2007). Is there a lot of stormwater or water running
through this area?
There is a steady flow of water form dam leakage and the L-LI pump area seal water. The
erosion was mainly from sheet flow from several sources, the major source being a old landfarm
next to the outfall. We have done extensive repair to this area this past year and there are no
erosion control issues in this area anymore.
Page 9 of 15

lW1616*1IIIIIIIyill
14. What is the S/G storage bldg?
a. We used to have the old Steam Generators from the plant stored there. They were radioactive
and were stored in this building prior to disposal. We have since disposed (if them (had them cut
up and removed from the site). The building is now being converted for storage of low level
radioactive materials. Mainly tools and equipment.
15. Are there any spent materials stored outside?
a. No. The only industrial activity is the cycle separators — to take out silt,from the lake water that is
raw water for their process. They are in a building. They dispose of,the silt somehow but JW
will ask the engineer how that is done. Not enough to get a truck —`the separators are about 2'x2',
and there are two of them. 4
b. The Cyclone Separator was replaced in 2002 with an Orival'Strainer'. lt"automatically
backwashes on high DP and the sand/silt/water mixture is discharged tlirougli SW Outfall 002.
There is no visible accumulation of sand/silt from this discharge at the outfall.F I gat this
f ti.
information from our Engineering folks.¢',"";`
Outfall 004:
7, r Q'
16. What is stored in the warehouse in outfall 004? is there loading and unloading there?
a. Paints and thinners. There is loadingandunloading through the roll -tip doors and mainly by
forklift. "There is all old loading dock but it is rarely used if !it all:
t
17. What is the "discarded materials building" in•outfall 003/4', '=
a. See answer to questions 14 and 15. + g Y a,
18. What is in the storage yard? —loading materials'for "disposal"? What kind of materials?
a. We mainly store steellmetal,and various+types of equipment. No oil or motorized equipment.
19, I see you had TSS exceedences fr6mloutfalls 004, 006:and 008 [above current benchmarks]. What do you think that
was from?
4,
a. We do not have limits on TSS97'! 004rwould be from the gravel storage yard. 006 would be from
gravel.in�the switchyard. 008 would'he from gravel in garage storage area. The majority of the
surface area near the Garage is pavedIbut we do have some gravel areas still. lam not awareof any
significant'erosion in these areas.
20. Are any PCB or any oil filled transformers draining to outfall 004? What about the outfalls near it? What about
outfalls.,33-369
a. None near.004 or,the outfalls along the discharge canal. None near 33 — 36 either. No PCBs.
21. What kind of hazardous waste are you storing in this area? From where? What outfall is this going to?
a. We do not have any Hazardous Waste stored near outfall 002. Our hazardous waste building
(90/180 day storage) is near our falls 003 and 005 oil the discharge canal. This is an enclosed
building with a sump/trench internal to the building. The sump/trench does not discharge outside
of the building. The building is also curbed and climate controlled. The hazardous waste is
generated by the site (both the McGuire Island and the plant).
22. What is the outfall located for the discarded materials storage building? Does that go to outfall 004?
Page 10 of 15

NCs000020
See above. The closest outfall would be 003, although 003, 004, and 005 are very close to each
other. The DiNISB is about 1000 feet from these outfalls and is separated by a large gravel storage
yard. The building is curbed and the storage area is below ground level.
23. There appears to be an area between outfall 004 and 005 that does not have an outfall located there — where does
it drain to?
All of these outfalls drain to the discharge canal.
24. What kind of hazardous waste is stored there'?
a. Used oil, asbestos, routine stuff from process, paint waste, waste from battery recycling, lab waste
they are generating in their lab. No radioactive materials stored in that building. This is the
same as the discarded materials storage building.
Outfall006:
25. What kind of transformers are stored in outfall 006?
a. Large oil filled transformers in the switchyard.a None contain PCBs.
s` % r.
26. Why do you think you had a..PCB exceedance in outfall 006?
h r
K.
a. I have no idea. All transformers and oil tilled equipPent'in the switchyard are PCB free. We
retrofitted all these years ago.
b. I discussed this with our lab folks.�O�ie of them indicated thatthe result could have been as a result
of an interference with Decachlor6bipheiiyl:;)I4am not a lab person but it is shown on sonic of the
other lab sheets from vendor labs (see the Nlay 2009_lab sheet from PACE Dabs in the package I sent.
The labs are requesting the lab datasheeets for"the"higl 'value' e got in 2005. It is in archive so it will
take a few days to get it I will send`you a'copy pce they have it. That is the only time we were over
the limit on PCB. .
27. Why did you have different reporting levels? Why dick yqu-use <500?
a. Not sure. f K ii1 have t0ook,at the data.
b. Difference in reporting limits for.athe ­<0.5 values (ug/L vs ng/L) and the 2007 value was from a
vendor lab and that is the reporting limit they used.
28. What;would be the so urces'of'these'in outfall 006 and 004?
-No PCBs
29. You had a,fire.in this area'- when?
a. No.
30. Have you done any retrofitting in this area that could have caused the large PCB discharges?
a. Years ago 20+ years ago.
31. Are any PCB or any oil filled transformers draining to outfalls near 006?
a. No
32. Dry weather discharge from fire system. I-]owever you state in your site review that there are structural areas and
interior floor drains and condensate from the equipment closed cooling system drain into the operating building sump
that is pumped out through outfall 006.
Page II of15

NCS000020
a. We have a fire suppression system for the transformers in the switchyard. Each transformer is
protected by this system. The primary leakage we observe at this outfall is from this. There is a
building (relay house) that contains switching gear and batteries primarily that is inside the
switchyard. I believe the drains in this building go to our waste water system but I will have to check
on that.
b. There are restroom facilities, sinks, drinking water fountains, etc. at the relay house in the switchyard
that drain to a septic system for the switchyard. There are also floor drains and sumps in the lower
elevation of the relay house that house the battery rooms. These drain to,the switchyard yard drain
system. The battery rooms are diked so if a battery/batteries leaked it, would be contained within the
room. The drains in the buildings are for draining rainwater or ariv type of water intrusion. No
chemical inputs.-, -�
33, What is SW037 — it appears to be draining to outfall 006, not from that area! Is that right? If so what is that area
draining to?
a. It does not drain to Outfall 006. It drains from the storun4ater trench around llie parameter of the
switchyard and then goes under the road to an area. that eventually drains to ii',wetland area. We
have had some problems with erosion in this aiea,_no so much from the switchyard but surface
draining during rain events from sheet flow. Welha ve done some repairs in this area and are
planning; some more.
b. JW had no idea why there was a PCB exceedance at that area., W will check sample as to why there
was 4100 ugA reading and see if there were anv,notes 6n it:'.AII the old transformers have already
been retrofitted. t�• s G
c. There is a concrete trench that goes,around the switch yard., SW37 drains that. See response to
question 26
d. 006 is in a different place and drains`both tvpes'of discharge from both the stormwater drains and
the trench that goes,arqund,it — hence whyjit is used for representative outfall status.
e. Have several.switch yards."There might have"been one to the north of highway 73. The other switch
yards all end: up going ,to the WW collection basin and are discharged out outfall 0115 —and
niomtored'under'the wastewater treatment NPDES permit.
f. They
µhad a spill iii;the switch yai'd`Ee1i 15`h, 1998. They had a transformer blow up and had a spill.
.A.01i t t.think thiWicould°have anything to do with the 4100 PCB monitoring event — the spill was
before that nioiitoring occurred."
outfall 00L4,1
w ..
34, Are the USTs'in outfall 008 what are stored in the underground storage tanks? Are they still used and filled?
a. We have 2 large US'Fs, one for diesel fuel the other for gasoline. These are still in use. I believe
the other.lJSTs'a"re no longer used and have been removed but I will have to check on that. They
were usedAo .store vehicle oils and transmission fluid. We now have an above ground tote system
that is used instead of the USTs. The tote tanks are housed inside of a building.
Verified that 4 USTs have been taken out of service (2,000 gallon Motor Oil UST, 1,000 gallon
transmission fluid UST and (2)1,000 gallon hydraulic oil USTs). We still have 3 in service, 12,000

35. Why do you think you had such low pl-l?
a. JW: A lot of the soil has low pH and might impact it. He will check on this.
Page 12 of 15

NCS000020
b. The soil in this area is characteristically low in pH. Groundwater sampling records indicate pl-I in
the range of high 5s to low 6s.
36. Are any PCB or any oil filled transformers draining to outfall 008?
a. We have one transformer outside of the garage. No PCBs. I will have to check on the capacity of the
transformer. It is inspected as part of our SPCC plan.
General:
37. Do you have any more data from any other outfalls? Can you please provide us with that?
a. I will have to check but I do not believe so. Their discharges would be similar in nature to the others
with representative outfall status,
38. Do you have a separate stormwater landfill permit?
a. No. We have one storm water permit for the whole site.- The landfill has a! leachate pond which is
routed to our waste water collection system.
The stormwater — would go to the ww collection system. It,is,piped from'tlie leachate pond to the WWTP.
That landfill is only Duke sites -- some offsite but only Duke, no publie,allowed. There are no other stormwater
I'll I outfalls besides what is draining to the leachate pond.
39. Where does the firing range drain to and what is it used for?
a. The firing range is for training our'Secuiity 6rce at the plant., It drains to a wooded area and
eventually to the Catawba River through the iVooded/grassy area.
Yes, there is stormwater but no outfall associated with the firing range. Only sheet flow from that area.
They do currently have an NCG01 because'they,are' expanding the site. JW will check on whether or not
they are putting in drainage into the firing range; and get back to me.
We will need to add 4 new outfalls as a result of the expansion of the firing range. I will update the drawing
and give you a description for cach.'I hope to have",' his complete and to you by 8/27 but I am not a drawing

In my l'as[ communicat�onttoyou on`fAitgust 20, 2010 I had indicated that we would need to permit 4
additional,ot tfalls associated,with the expansion of the Security Firing Range. After reviewing our
Supplcmentai`lhformation provided with our re-newal application, it appears we can exempt the Firing
Range Outfalls under40 CFR' 122.26 (b) (14), the Industrial Activity Exclusion. These storm water
discharges are sc�kate_,frQiri that of our plants other industrial activities and is not mixed with those
discharges. The specific wording we are using for excluding these discharges is included below.
.....`Che 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 drained from the above described areas..."
I still owe you a copy of the PCB sample, lab bench sheets, which I hope to have by the end of business
today. I will send you a copy of them as soon as .1 receive them.

NCS000020 McGuire Nuclear Station — Mecklenburg County
Site inspection conducted on October 13, 2010, by Michael Parker. Facility contact: Mr. John
Williamson. Current NPDES SW permit expired on January 31, 2008. The facility is in the business
of producing electricity via nuclear power generation. The various areas that were evaluated during
the site visit included the Hazardous Waste/Material Storage area, Transformer Switch Yard area,
Maintenance Shop area; an old onsite Landfill, and the Firing Range.
Stormwater outfalls draining the Hazardous Waste/Material Storage area include outfalls 003 — 005,
015 — 019, 020 — 022, 029 — 032, and 033 - 036. The permittee has requested and received
representative outfall status in 1998 for all these outfalls except 004, which is the outfall where
analytical testing in being conducted. Representative outfall status for outfalls 003, 005, 015 — 022, and
033 — 036 is appropriate. All these outfalls receive drainage from an area that is partially paved, but is
mostly gravel. The fines associated with the gravel are a likely source for the elevated TSS readings
that have been reported at this outfall. Unless a new SW sampling location is selected or the proposed
benchmark values are modified, this facility will likely continue to have difficulty in consistently
complying with the benchmark TSS levels proposed in the new SW permit. According to Mr.
Williamson, there are no immediate plans to pave this area, so the potential for more benchmark "I'SS
exceedances will exist. The Hazardous Waste storage area is in an enclosed building, which is also
recessed into the ground so there is no possibility that a material could leak and make its way outside
of the building and possibly come into contact with stormwater. The area adjacent to the Hazardous
Waste storage area is used for material storage (mostly metal products), and is completely graveled.
Stormwater outfalls associated with the Transformer Switch Yard include outfalls 006, 007, 009, 010 —
014, 023 — 028, and 037. Representative outfall status was obtained for outfalls 007, 009, 010 — 014,
023 — 028, and 037 and is appropriate based on observation made during the site visit. The permittee
is conducting analytical testing at outfall 006. Existing, on -site transformers in this area do not contain
PCB contaminated oils, so a source for the PCB detection found during analytical testing in 2005
cannot be found. This area is entirely covered by gravel, which would offer an explanation as to the
occasional TSS benchmark exceedance this facility has recorded. The majority of these outfalls do not
discharge directly to surface waters or a drainage feature, but empty onto the ground and would have to
travel several hundred feet through heavy vegetative cover to reach surface waters.
Stormwater outfall(s) associated with the now closed Landfill include outfall 002. In recent years, the
area surrounding this outfall had experienced significant erosion during to sheet flow from several
sources — primarily an old land fann. Stabilization efforts have been successful and vegetation has
been established. There were no sedimentation issues noted during the site visit to this area.
There is one stormwater outfall associated with the Equipment Maintenance facility (008). This outfall
also recorded a PCB hit back in 2003; however, the only transformer located onsite is a non -PCB laden
transformer that serves the building. Mr. Williamson had no idea where the PCB detection may have
come from given that there are no PCBs stored at this site. There have also been a number of pl-I
benchmark exceedances and a couple TSS exceedances recorded at this outfall. The area around the
maintenance facility is partially paved; however, there is an area adjacent to the outfall that is gravel,
which might explain the occasional elevated TSS readings. There was no visual evidence as to why
slightly lower pH levels might be occurring at this outfall, however, Mr. Williamson indicated that in
absence of a direct link, one possible source may be low soil pl-I typical of the surrounding area.

Page Two
There are at least 4 stormwater outfalls associated with the facility's firing range. This range is used to
conduct onsite training of security personnel stationed at McGuire. The range, however, is on a
separate part of the company's property and is far removed from the industrial activities associated
with this permit. The outfalls in this area discharge to a heavily vegetated area adjacent to the range
and are well removed from surface waters. Duke Power has chosen to not apply for coverage of these
outfalls given that they are not associated with the industrial activities of this site and do not combine
with any other permitted outfall prior to discharging.
Proposed changes to the permit
The draft permit contains a number of changes from the previous permit. These changes/additions
include;
• It is proposed that BOD/COD testing be added to outfall 004 based on the proximity of the
hazardous waste storage building. From observations made during the site visit, there does not
appear to be a source that would produce contaminants where BOD/COD testing would be
considered beneficial. It is recommended that the testing for these parameters not be added to
the permit at this time given the lack of a possible source of these contaminants.
• The re -wording of the language for the benchmark value for PCBs will be changed to reflect a
wording consistent with the standard wording in current NPDES wastewater permits. This
Office has no objection to this change.
• Analytical monitoring has been changed from the previous permit (quarterly first and last years
and annually during the middle years) to semi-annually throughout the term of the permit.
Total precipitation for each storm event must also be documented. This Office has no objection
to this change.
• Benchmark values for all analytical monitoring have been added to the permit. Exceedances of
any benchmark value will require tiered compliance activities depending on the number of
benchmark exceedances recorded. This Office has no objection to this addition to the permit.
• The flow reporting requirement has been removed from the permit and replaced by a total
rainfall parameter. This will make the permit more consistent with other stormwater permits
and is consistent with current DWQ permitting strategy.
Overall, the site is well maintained and the permittee is updating the site's SPPP on an annual basis. A
review of the facility's SPPP found that the Plan is complete and accurate with respect to the various
SPPP components required by the subject permit.
In conclusion, it is recommended that the subject SW permit be reissued with consideration given to
the comments/recommendations as contained in ,this report.

Revised Permit Recommendations: Analytical Monitoring:
1. Because the data they have submitted from their site have exceeded our current benchmarks,, the same
parameters have been kept in Duke's permit as its previous permit cycle.
a. I have added BOD and COD to the permit in SWO04 to capture any other unknown organichnorganic
compounds — I am especially concerned about areas near and around the hazardous waste storage area.
If outfalls are be re-evaluated, BOD & COD must be measured at appropriate outfalls.
b. PCBs have been kept in the permit as they have had a significant PCB reading from outfall 006 and as
these are extremely toxic/hazardous substances — both to human and aquatic",! ife?. Additionally, there are
_ ,_ transformers located allover the property. Instead of a benchmark number'of zero, the wording "There
shall be no discharge of polychlorinated biphenyl compounds" and "T..permittee shall report rcsalts
either as "Non -Detect" (include the reporting level), or as the result=in;�i /f E1ny detection about he
reporting level shall be deemed to be above the benchmark" was _added to'thc�permit. After consultin-
"' with classifications and standards (Connie Brower) and NPDES!WW(Serger;Cliernikov) it was deCi{;;ed
that this wording was clearer than using the benchmark of.., 0�.�as the current techmqucs_cannot �.,tual[y
test to 0. Quantitation limits (PQLs) of PCBs (usually at'or near I µg/L) are mucli'higlier than aquatic
life standards (1 ng/L). Additionally, PQLs will ch tinge -daily w ihin and between labW,11ese factors
make it difficult to write the action level as a nurriene,benchmark�Therefore SPU has chosen to write
the benchmark in this manner so that any detection over. -the P``Qi.,;is an exceedence of the benchmark.
�L•h.'tiR
This method will also incorporate advances in methods UKB"detection levels. This is also more
consistent with NPDES WW's wording,
c. TPH is recommended because of USTs in outfall 008, llaz waste,and•oil• storage in outfall 004, and oil
filled transformers all over the ro ertY,: rnc.ludiii Y outfall 006V
s
d. pH has been kept in the analytical momtonng requirements. ..
2. All analytical monitoring has been set to semi=annuallyduringya}representative storm event as defined in Part lI
Section B. The permittee must also document-il etotal•pfecipitation;foreach event. If no discharge occurs
during the sampling period, the permittee inAf, ubinit "'Tonitoring report indicating "No Flow" within 30 days

The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the

receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stonnwater. discharges. Additional information is provided in Part II Section
A.
2. Additional requirements for the Stonnwatcr Management Plan have been specified in Part Il Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part I1 Section A.
The plan must also be updated annually to include a list of significant spills and to cdrt fy that the outfalls do not
contain non-stormwater discharges. '';- ;
4. The facility must now implement a semi-annual Facility Inspection Program ofjk ••,"site's stormwater

a. We"are'subject to Mecklenburg County and the City of Huntersville watershed restrictions. We have
3 constructiom;pr6jects pending right now. One has an active Erosion Control plan associated with
it. The 'otlier;2 construction projects are rather small and are under the 1 acre surface area
requirements•Rfor an erosion control plan. All building projects and land disturbing activities on -site
require the use of BMPs for Storm Water control.
5. Why did you do analytical sampling on different dates?
a. I have not looked at the data. I will have to check.
JW to JJ: The sampler went off on the wrong day — it started to go off but then stopped so they had
to take it another day. The;; have 3 automatic samplers at sampling sites.

13. There appears to be some erosion (Re: MRO site visit in 2007). Is there a lot of stormwater or water running
through this area?
a. 'There is a steady flow of water form dam leakage and the LLI pump area seal water. The
erosion was mainly from sheet flow from several sources,;the major source being a old landfarm
next to the outfall. We have done extensive repair to this area this past year and there are no
erosion control issues in this area anymore.

14. What is the S/G storage bldg?
a. We used to have the old Steam Generators from the plant stored there. They were radioactive
and were stored in this building prior to disposal. We have since disposed of them (had them cut
up and removed from the site). The building is now being converted for storage of low level
radioactive materials. Mainly tools and equipment.
15. Are there any spent materials stored outside?
a. No. The only industrial activity is the cycle separators — to take out silt.6 m the lake water that is
raw water for their process. They are in a building. They dispose of the"silt:somehow but JW

a. Norte, iiearv004 oi=4he outfalls along the discharge canal. None near 33 — 36 either. No PCBs.
21. What kind of hazardous`'waste are you storing in this area? From where? What outfall is this going to?
a. We do nzt t. ve any Hazardous Waste stored near outfall 002. Our hazardous waste building
(90/180 day storage) is near our falls 003 and 005 on the discharge canal. This is an enclosed
building with a sump/trench internal to the building. The sump/trench does not discharge outside
of the building. The building is also curbed and climate controlled. The hazardous waste is
generated by the site (both the McGuire Island and the plant).
22. What is the outfall located for the discarded materials storage building? Does that go to outfall 004?
Page 10 of 15

NCS000020
a. See above. The closest outfall would be 003, although 003, 004, and 005 are very close to each
other. The DMSB is about 1000 feet from these outfalls and is separated by a large gravel storage
yard. The building is curbed and the storage area is below ground level.

23. There appears to be an area between outfall 004 and 005 that does not have an outlall located there- where does
it drain to?
All of these outfalls drain to the discharge canal.
24. What kind of hazardous waste is stored there?
a. Used oil, asbestos, routine stuff from process, paint waste, was.t-, froth .battery recycling, lab waste
they are generating in their lab. No radioactive materials storex m•that,building. This is the
same as the discarded materials storage building. £

Page 1 1 of 15

NCs000020
a. We have a fire suppression system for the transformers in the switchyard. Each transformer is
protected by this system. The primary leakage we observe at this outfall is from this. There is a
building (relay house) that contains switching gear and batteries primarily that is inside the
switchyard. 1 believe the drains in this building go to our waste water system but I will have to check
on that.
b. There are restroom facilities, sinks, drinking water fountains, etc. at the relay house in the switchyard
that drain to a septic system for the switchyard. There are also floor drains and sumps in the lower
elevation of the relay house that house the battery rooms. These drain to;the switchyard yard drain
system. The battery rooms are diked so if a battery/batteries leaked it would be cont?ined within the
V t room. The drains in the buildings are for draining rainwater or anytype�of watr:lmtrusion. No

a. It does not drain to Outfall 0. It drains from the storm water trench aroun[lfhe, pf rameter of the

switchyard and then goes under the road to an area.that eventually drains to a•;wetlan`d area. We
have had some problems with erosion in this .dreai ,.no so much \from the switchyard but surface
draining during rain events from sheet flow. We liavetidone-some repairs in this area and are
planning some more.;

34. Are the _`USTs-'in outfall'00& what are stored in the underground storage tanks? Are they still used and filled?
a. We liayer2,large USTs, one for diesel fuel the other for gasoline. These are still in use. I believe
r:
the otlier USTs'are no longer used and have been removed but I will have to check on that. They
were used" store vehicle oils and transmission fluid. We now have an above ground tote system
that is used'instead of the USTs. The tote tanks are housed inside of a building.
b. Verified that 4 USTs have been taken out of service (2,000 gallon Motor Oil UST, 1,000 gallon
transmission fluid UST and (2)1,000 gallon hydraulic oil USTs). We still have 3 in service, 12,000
gallon Gasoline UST, 12,000 gallon Diesel Fuel UST, and a 2,000 gallon Used Oil UST.
35. Why do you think you had such low pH?
a. JW: A lot of the soil has low pH and might impact it. lie will check on this.,
Page 12 of 15

NCS000020
b. The soil in this area is characteristically low in pH. Groundwater sampling records indicate pH in
the range of high 5s to low 6s.
36. Are any PCB or any oil filled transformers draining to outfall 008?
a. We have one transformer outside of the garage. No PCBs. 1 will have to check on the capacity of the
transformer. It is inspected as part of our SPCC plan.

The stormwater go to the ww collection system..ltisipiped from?the,leachate pond to.the WW 1'P.
That landfill is only Duke sites — some offsite but only Duke, no pubhc'allowed. There are no other stormwater
outfalls besides what is draining to the leachate pond. bb�

Permit No. NCS000020
B, Paragraph 5. The permittee shall re -certify annually that the.stormwater
outfalls have;.been evaluated for the presence of non-stormwater discharges.
Stonnwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate.the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing
.the methods of operations and/or storage practices to eliminate or reduce exposure
of mate'V;Id's and processes to stormwater. Wherever practical, the permittee shall
prevent' exposure of all storage areas, material"handling operations, and
manufacturing or fueling operations. In arca.s.wliere elimination of exposure is
not practical, the stormwater management plan shall -•document the feasibility of
diverting the stormwater runoff away ffrrooKareas of potential contamination.
(b) Secon6ry Containment kequiremerits and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section
313 of Title III of the Superfun�d Amend em nts and Reauthorization Act (SARA)

order to prevent leaks and spills 'from contaminating stormwater runoff. A table
ch tanks and stored materials and their associated secondary
or summary of all'su
containment areas,shall be•maintained. If the secondary containment devices are
connected to storniwater•conveyance systems, the connection shall be controlled
byma-_ ually activated valves or other similar devices (which shall be secured
closed with a locking -mechanism), and any stormwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) responsible for implementing the
SPRP shall be identified in a written list incorporated into the SPRP arid signed and dated
by each individual acknowledging their responsibilities for the plan. A responsible
Part 11 Page 2 of 10

Permit No. NCS00002'0
person shall be on -site at all times during facility operations that have the potential to
contaminate stonmwater runoff through spills or exposure of materials associated with the
facility operations. The SPRP must be site stormwater specific. Therefore, an oil Spill
Prevention Control and Countermeasure plan (SPCC) may be a component of the SPRP,
but may not be sufficient to completely address the stormwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference into the
SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventa"ve ;
maintenance and good housekeeping program shall be developed. The prG:)ram shall list
all stonnwater control systems, stormwater discharge outfalls, all on -site and adjacent
surface waters and wetlands, industrial activity areas (including material stora€e areas,
material handling areas, disposal areas, process areas,^Ioading and unloading areas, and
haul roads), all drainage features and structures;�andexisting structural BMPs. The
program shall establish schedules of inspections, mainrenance,,and housekeeping
�r facility activities of stormwater control systems, as well as, tacility•equipment, facility areas, and
facility systems that present a potential for stormwater exposure or stormwater pollution.
Inspection of material handling areas and regular cleaning schedules of these areas shall
be incorporated into the program. Timely compliance with the established schedules for
inspections, maintenance, and housek eping shall-�?be recorded in writing and maintained
in the SPPP.
5. Employee Training. Trammg programs shall be developed and training provided at a
minimum on an annual basis -for facility personnel with responsibilities for: spill response
and cleanup, preventative maintenance activities, and for any of the facility's operations
that have the potential to contaminate stormwater runoff. Facility personner•l or team)

shall be documented byethe`signature of each employee trained.
b. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The penmittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table i. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches.of rainfall. The time
between this storm event and the previous storm event measuring greater than 0.1 it'ches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 how s . For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a discharge begins within 10 hours.

SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status, and shall be performed as specified in Table 4, during the analytical
monitoring event. [If analytical monitoring is not required, the permittee still must conduct semi-
annual qualitative monitoring.] Qualitative monitoring is for the purpose of evaluating the
effectiveness of the Stormwater Pollution Prevention Plan (SPPP) and assessing new sources of
stonnwater pollution. - �-
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall
document the suspected cause of the condition and any actions taken in response to the
discovery. This documentation will be maintained with the SPPP. '=,''

NCS000020 McGuire Nuclear Station — Mecklenburg County
Site inspection conducted on October 13, 2010, by Michael Parker. Facility contact: Mr. John
Williamson. Current NPDES SW permit expired on January 31, 2008. The facility is in the business
Of producing electricity via nuclear power,generation. The various areas that were evaluated during
the site visit included the Hazardous Waste/Material Storage area, Transformer Switch Yard area,
Maintenance Shop area, an old onsite Landfill, and the Firing Range.
Stormwater outfalls draining the Hazardous Waste/Material Storage area include outfalls 003 — 005,
015 — 019, 020 — 022, 029 — 032, and 033 - 036. The permittee has requested and received
representative outfall status in 1998 for all these outfalls except 004, which is the outfall whcre
analytical testing in being conducted. Representative outfall status for outfalls 003, 005, 015 — 022, and
033 — 036 is appropriate. All these outfalls receive drainage from an area that is partially paved, but is
mostly gravel. The lines associated with the gravel are a likely source for the elevated TSS readings
that have been reported at this outfall. Unless a new SW sampling location is selected or the proposed
benchmark values are modified, this facility will likely continue to have difficulty in consistently
complying with the benchmark TSS levels proposed in the new SW permit. According to Mr,
Williamson., there are no immediate plans to pave this area, so the potential for more benchmark TSS
excecdanccs will exist. The Fazardous Waste storage area is in an enclosed building, which is also
recessed into the ground so there is no possibility that a material could leak and make its way outside
of the building and possibly come into contact with stormwater. The area adjacent to the Hazardous
Waste storage area is used for material storage (mostly metal products), and is completely graveled.
Storrnwater outfalls associated with the Transformer Switch Yard include outfalls 006.007. 009, 010 —
014, 023 — 028, and 037. Representative outfall status was obtained for outfalls 007, 009, 010 — 014,
023 — 028, and 037 and is appropriate based on observation made during the site visit. The permittee
is conducting analytical testing at outfall 006. Existing, on -site transformers in this area do not contain
PCB contaminated oils, so a source for the PCB detection found during analytical testing in 2005
cannot be found. This area is entirely covered by gravel, which would offer an explanation as to the
occasional TSS benchmark exceedance this facility has recorded. The majority of these outfalls do not
discharge directly to surface waters or a drainage feature, but empty onto the ground and would have to
travel several hundred feet through heavy vegetative cover to reach surface waters.
Storniwater outfall(s) associated with the now closed Landfill include outfall 002. In recent years, the
area surrounding this outfall had experienced significant erosion during to sheet flow from scvcral
sources — primarily an old land farm. Stabilization efforts have been successful and vegetation has
been established. There were no sedimentation issues noted during the site visit to this area.
There is 011c stO1`nI1v3ter outfall associated with the Equipment iMairitcnance facility (008). This outfall
also recorded a PCB hit back in 2003; however, the only transformer located onsite is a nori-PCB laden
transformer that serves the building. Mr. Williamson had no idea where the PCB detection may have
come from given that there are no PCBs stored at this site. There have also been a number of pH
benchmark excecdanccs and a couple TSS excecdanccs recorded at this outfall. The area ground the
maintenance facility is Martially paved; however, there is an area adjacent to the outfall that is gravel,
which might explain the occasional elevated TSS readings. There was no visual evidence as to why
slightly lower pH levels might be occurring at this outfall, however, Mr. Williamson indicated that in
absence of a direct link, one possible source may be low soil pl-1 typical of the surrounding area.

Page "1-wo
There are at least 4 stornwater outfalls associated With the facility's firing range. This range is used to
conduct onsite training of security personnel stationed at McGuire. The range, however, is on a
separate part of the company's property and is far removed from the industrial activities associated
with this permit. The outfalls in this area discharge to a heavily vegetated area adjacent to the range
and are well removed from surface waters. Duke Power has chosen to not apply for coverage of these
outfalls given that they are not associated with the industrial activities of this site and do not combine
with any other permitted outfall prior to discharging.
Proposed changes to the permit
The draft permit contains a number of changes from the previous permit, These changes/additions
include:
It is proposed that BOD/COD testing be added to outfall 004 bases] on the proximity of the
hazardous waste storage building. from observations, made during the site visit, there does not
appear to be a source that would produce contaminants where BOD/COD testing would be
considered beneficial. It is recommended that the testing for these parameters not be added to
the per•init at this time given the lack of a possible source of these contaminants.
Y The re -wording of the language for the benchmark, value for PCBs will be changed to reflect a
wording consistent with the standard Wording in current NPDES wastewater permits. This
Office has no objection to this change.
o Analytical monitoring has been changed from the previous perniit (quarterly first and last years
and annually during the middle years) to semi-annually throughout the term of the permit.
Total precipitation for each storm event must also be documented. This Office has no objection
to this change.
Benchmark values for all analytical monitoring have been added to the permit. Exceedances of
any benchmark value will require tiered compliance activities depending on the number of
benchmark exceedances recorded. This Office has no objection to this addition to the permit.
e The flow reporting requirement has been removed from the permit and replaced by a total
rainfall parameter. This will make the pennit more consistent with other stormwater permits
and is consistent with current DWQ permitting, strategy.
Overall, the site is Well maintained and the pernittee is updating the site's SPPP on an amlual basis. A.
review of the facility's SPPP found that the Plan is complete and accurate with respect to the various
SPPP components required by the subject permit.
In conclusion, it is recommended that the subject SW permit be reissued with consideration given to
the comments/recommendations as contained in this report.

To: [e-mail]
Mr. Williamson,
Given that these samples were taken on the last day of the second quarter, with due
diligence taken for sampling in the third quarter, I think it is acceptable to count
these for your third quarter sampling. However, if you have collected (or will
collect) samples during the third quarter and are asking to substitute those from
8/31/06, we would no_ accept the 8/31 samples in lieu of the more recent ones.
Please document this carefully on the DMRs submitted to DENR. I will also copy this
e-mail to the NCS000020 permit file so future reviewers are aware of the
accommodation.
If you have any ques:�ions, please let me know.

Bradley,
We are currently in the 4^th year of our storm water permit. During this year we
are required to take quarterly storm water samples.
We were able to get 3 valid storm water samples on 8/31/06 (we had our samplers out
getting ready to pull our 3^rd quarter samples).
We would like to use these samples to meet our 3^rd quarter sampling if NCDENR does
not object. These samples were in addition to samples pulled for the 2^nd quarter.
Please advise if this is acceptable to NCDENR..
Thanks !!

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part Ill, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility's location in relation to transportation
routes and surface waters, the name of the receiving water(s) to which the
stormwater outfall(s) discharges, or if the discharge is to a municipal separate
storm sewer system, the name of the municipality and the ultimate receiving
waters; and accurate latitude and longitude of the point(s) of discharge.
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices.
(c) A site map drawn to scale with the distance legend indicating location of
industrial activities (including storage of materials, disposal areas, process areas
and loading and unloading areas), drainage structures, drainage areas for each
outfall and activities occurring in the drainage area, building locations, existing
BMPs and impervious surfaces, and the percentage of each drainage area that is
impervious. For each outfall, a narrative description of the potential pollutants
which could be expected to be present in the stormwater discharge.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the 3 previous years and any corrective actions taken to mitigate spill
impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements, found in Part RI, Standard Conditions, Section
B, Paragraph 3.
2. Stormwater Management Plan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
Part 11 Page 1 of 6

Permit No. NCS000020
(a) Feasibility Study. A review of the technical and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater. Wherever practical, the permittee shall
prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from areas of potential contamination.
(b) Secondary Containment Schedule. A schedule to provide secondary containment
for bulk storage of liquid materials, storage of Section 313 of Title III of the
Superfund Amendments and Reauthorization Act (SARA) water priority
chemicals, or storage of hazardous substances to prevent leaks and spills from
contaminating stormwater runoff. if the secondary containment devices are
connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices [which shall be
secured with a locking mechanism] and any stormwater that accumulates in the
containment area shall be at a minimum visually observed for color, foam, outfall
staining, visible sheens and dry weather flow, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by the material stored within the containment area. Records
documenting the individual making the observation, the description of the
accumulated stormwater and the date and time of the release shall be kept for a
period of five years.
(c) BMP Summary. A narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease
separation, debris control, vegetative filter strips, infiltration and stormwater
detention or retention, where necessary. The need for structural BMPs shall be
based on the assessment of potential of sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. A responsible person shall be on -site at all times during facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, a SPCC plan may be a component of the SPRP, but may
not be sufficient to completely address the stormwater aspects of the SPRP. The common
elements of the SPCC with the SPRP may be incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. Inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.
Part II Page 2 of 6

Permit No. NCS000020
5. Employee Training. Training schedules shall be developed and training provided at a
minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff. Facility personnel
(or team) responsible for implementing the training shall be identified.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a'time schedule to the Director for modifying the Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
8. Facility Inspection Program. Facilities are required to inspect all stormwater systems on
at least a semiannual schedule, once in the fall (September -November) and once in the
spring (April - June). The inspection and any subsequent maintenance activities
performed shall be documented, recording date and time of inspection, individual(s)
making the inspection and a narrative description of the facility's stormwater control
systems, plant equipment and systems. Records of these inspections shall be
incorporated into the Stormwater Pollution Prevention Plan.
Stormwater discharge characteristic monitoring as required in Part II of this permit shall
be performed in addition to facility inspections.
9. Implementation. The permittee shall document all monitoring, measurements,
inspections and maintenance activities and training provided to employees, including the
log of the sampling data and of activities taken to implement BMPs associated with the
industrial activities, including vehicle maintenance activities. Such documentation shall
be kept on -site for a period of five years and made available to the Director or his
authorized representative immediately upon request.

SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified below in Table 3. Qualitative
monitoring is for the purpose of evaluating the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and assessing new sources of stormwater pollution. No analytical tests
are required. Qualitative monitoring of stormwater outfalls does not need to be performed during
a representative storm event.
In the event an atypical condition is noted at a stormwater discharge outfall, the Permittee shall
document the suspected cause of the condition and any actions taken in response to the
discovery. This documentation will be maintained with the Stormwater Pollution Prevention
Plan.
All qualitative monitoring will be performed twice per year, once in the spring (April - June) and
once in the fall (September - November).

Subject: NPDES Stormwater Permit Renewal
McGuire Nuclear Site
Permit Number NCS000020
Mecklenburg County
Dear Permittee:
Your facility is currently covered for stormwater discharge under NPDES Permit NCS000020. This permit expires
on November 30, 1999. In order to assure your continued coverage under your permit, you must apply to the
Division of Water Quality (DWQ) for renewal of your permit. To make this renewal process easier, we are
informing you in advance that your permit will be expiring. Enclosed you will find an individual permit renewal
application form, supplemental information request, and Stormwater Pollution Prevention Plan certification. Filing
the application form along with the requested supplimental information will constitute your application for renewal
of your permit. The application form must be completed and returned along with all requested information by June
14, 1999 in order to constitute a timely renewal filing.
Recent legislation modified the fee structure for DWQ permits. Renewal fees have been eliminated and annual fees
have been changed. The new annual fee for your permit is now $715.00 (you will be invoiced later this year for
your annual fee.) A copy of the new fee schedule is enclosed in this package.
Failure to request renewal by June 14, 1999 may result in a civil assessment of at least $250.00, Larger penalties
may be assessed depending on the delinquency of the request. Discharge of stormwater from your facility without
coverage under a valid stormwater NPDES permit would constitute a violation of NCGS 143-215.1 and could
result in assessments of civil penalties of up to $10,000 per day.
If you have any questions regarding the permit renewal procedures please contact Bill Mills of the Stormwater and
General Permits Unit at [phone], ext. 548.
Sincerely,
bCI / y
