Your facility is currently covered for stormwater discharge under NPDES Permit NCS000021. This permit
expires on 4/30/2013. To assure consideration for continued coverage under your individual permit, you
must apply to the Division of Water Quality (DWQ) for renewal of your permit. Enclosed you will find an
individual permit Renewal Application Form, Supplemental Information request, and Stormwater Pollution
Prevention Plan Certification for your facility.
Filing the application form along with the requested supplemental information will constitute your
application for renewal of this permit. Until your permit renewal is completed and you receive a new permit,
please continue to comply with all conditions and monitoring requirements in your expired NPDES
stormwater permit.
The application and supplement must be completed and returned to DWQ by November 1. 2012, Failure to
request renewal within this time period will result in delay of your permit renewal and may result in a civil
assessment. Discharge'of stormwater from your facility without coverage under a valid stormwater NPDES

Subject: Request for TSS Relief
Permit No. NCS000021
Seimens — Charlotte Turbine Generator
Plant
Mecklenburg County, North Carolina
Dear Mr. Crowther:
This Office is in receipt of your letter dated November 19, 2010, requesting temporary relief from
the benchmark value for Total Suspended Solids (TSS) as contained in the subject stormwater permit.
The reason for your request is due to ongoing construction activities at the site that have disturbed
areas in and around existing stormwater outfalls. Recent sampling of these outfalls has documented
TSS values that have exceeded the benchmark value for this parameter which is 100 mgll. In your
letter you indicated that as long as these land disturbing activities continue, there is a high probability
that additional benchmark exceedances will occur until such time as the construction activities have
been completed and the site stabilized. You also noted that additional sedimentation control measures
have been implemented by the construction contractor to help reduce off -site sediment loss.
In reviewing your request, it was noted that the ongoing construction activities are also covered
by a separate construction stormwater permit (NCG010000), which you should have received when you
received your sediment and erosion control plan approval from the Mecklenburg County Land
Development office (MCLD). Compliance with the terms and conditions of this permit is expected
during the time the site is considered to be active by MCLD staff. Although this permit does not require
analytical testing, Seimens is expected to take every measure necessary to prevent sediment from
ongoing construction activities to enter stormwater drainage inlets that exist in the vicinity of the
construction zone.

Based on our review of this request, this Office recommends that Seimens continue all
analytical testing as required by the subject stormwater permit, however, the suspension of additional
Tier II level monitoring is granted for TSS at outfall 005 until such time as the ongoing construction
activities are complete and the area adjacent to the outfall is stabilized.
If you have any questions concerning this matter, please contact Mr. Michael Parker at (704)

REF.: Request Temporary Relief from Total Suspended Solids Benchmark
Permit No. NCS000021
Mr. Robert Krebs, Environment Regional Supervisor:
This letter serves to request temporary relief from the Total Suspended Solids (TSS) benchmark
for Outfall (OF)-005 as currently defined in permit No. NCS000021 for the Siemens, Charlotte
facility located at 5101 Westinghouse Blvd, Charlotte, NC 28273. This relief would be for the
duration of the current construction project with the remainder of the benchmarks to remain in
effect.
During our last sampling event (reference attached memorandum) we significantly exceeded the
benchmark for TSS associated with OF-005 due to construction activities.
After review of the sample report, Blythe Development Co. personnel in concert with Siemens
EHS personnel inspected and immediately implemented additional control procedures for this
location. These controls were in place and inspected on 11/19/2010. Additionally, Mr. Adam
Desforges, Blythe Superintendent, reviewed these controls with Charlotte -Mecklenburg
regulators who have concurred with our efforts.
This request comes as the result of conversations and coordination with Mr. Michael Parker,
Environmental Engineer, SWP.
Please call or email if further clarification is required.

REF.: MEMORANDUM for Year 3-Period 1 Sampling Event on 10/14/2010
Permit No. NCS000021
To Whom It May Concern:
This letter serves as notification of our Tier One efforts associated with Total Suspended Solids
(TSS) benchmark exceedance during our sampling event on October 14t", 2010 concerning
Outfalls (OF) 005, 007, and 009. Please reference the Storm Water Compliance and Industrial
Observations report date October 14, 2010—S&ME Project No. 1356-10-001.
All three outfalls have been adversely affected by the ongoing construction projects with an
explanation for each below:
OF-005 benchmark 100 mg/I: actual 410 mgll
OF-005 is located at the base of the spray pond dam and immediately adjacent to a haulage
road used by heavy construction equipment. The actions below have been agreed upon
between Blythe Construction and Siemens on 11/09/2010 with a completion date of 11/19/2010.
1. Distribute rip-rap/gravel on the east side of the haul road to stabilize the surface and
prevent further collapse as well as protect the culvert and provide a small level of filtration.
2. Cover the concrete drain collection box at the base of the dam associated with OF-005.
3. Install "waddles" downstream of the OF-005 collection box to provide sedimentation
filtration.
4. Install erosion fencing along the base of the dam, west side of the road and north of the
pond outlet
Additionally, we are discontinuing monitoring of this location as it is not representative of our
current industrial activities. We will resume monitoring after completion of construction activities
and restoration of the haul road and surrounding environs.
OF-007 benchmark 100 mg/I: actual 100 mgll
OF-007 is now associated with a small parking lot and the final grading and soil stabilization had
not,been completed. All final grading has been completed and grass has taken root with
associated hay covering as of 11/10/2010.
OF-009 benchmark 100 mgII: actual 130 mgll
At the time of the sampling event logging operations and soil core sampling were being
conducted around OF-009. This outfall has since been retired as it is geographically in the
middle of the primary construction zone. Please reference the associated letter of intent dated
July 16, 2010 in your files for our facility.

fees for your facility have not been paid. The total amount presently owed is $715.00. Please return
your payment to the address listed below by September 16, 2010.
In addition, please be advised that failure to pay the annual fee is grounds for revocation of your permit,
as documented at 15A NCAC 2H.0105 (b)(4). This letter serves as notice that the Division will refer
uncollected fees to the North Carolina Attorney General's Office for collection through the courts unless
payment in the amount of 7$ 15.00 is received by September 16, 2010. Further enforcement'action
[ including the revocation of the permit, imposition of civil penalties, and notification of the county health
department] may also occur if the fees remain unpaid.
Make checks payable to NC DENR, include the permit number on the check, and send the fee payment

. REF.: REQUEST FOR OUTFALL CHANGE FOR STORMWATER PERMIT NCSOti�ti'02'�
Dear Sirs:
This letter serves as notification of our intent to remove Outfall 009 (OF 009) from our stormwater
monitoring under permit NCS000021 as well as our Stormwater Pollution Prevention Plan. We
will be expanding our current facility and OF 009 which drains from the southwest corner of our
employee parking lot will be destroyed as this area will become a new 388,000 sq. ft. factory
building. Outfall 002 may be impacted at a later date pending final construction planning and
grading for which we will keep you informed. -We anticipate that this construction will last until
late 2012 at which time we will update our plan appropriately.
Additionally, please reference the letter dated 12 February, 2009 which established OF 009.
Please call or email if further clarification is required.

Delta Project No.: 5EO909179P
D E LL `r A Dear Mr, Crowther:
Delta Consultants (Delta) is pleased to provide this report
summarizing the water quality study conducted at the above -
referenced facility. The scope of work for this project was provided
in Deltas Environmental Consulting Services Proposal dated
December 14, 2009 and consisted of collecting water samples for
laboratory analysis of copper. Composite water samples were
collected over a period of four days (four separate composite
samples) from the pump house filter back flush discharge and from
the cooling spray pond discharge.
BACKGROUND
Siemens Energy, Inc. (SEI) extracts water from Wither's Cove of
Lake Wylie at a rate of 3,500 gallons per minute (gpm) through a
pump house located adjacent to the cove. On a daily basis at
approximately noon, the filters of the pump house are back flushed
to clean them" of sediment, rock, and organic debris pumped from
the lake and captured by the filters. This process helps to extend
the working life of the pumps. The water used for the back flush is
extracted directly from the lake and subsequently discharged to the
lake untreated. Additionally, the water Extracted from the lake
passes through the facility power house for use in HVAC chillers as
needed (dependent on facility heat load) and is then discharged
untreated to the cooling spray pond. This loop has a continuous
flow of 3,500 gpm regardless of whether the chillers are operating.
Makeup water for the facility boiler, cooling water tower, non -
potable uses, and process cooling water is extracted and treated
as needed for each usage requirement. Any blowdown water from
these processes is discharged to the sanitary sewer per the
existing permit with Charlotte -Mecklenburg Utilities Department,

The cooling spray pond subsequently discharges into Wither's Cove of Lake Wylie.
Mecklenburg County Land Use and Environmental Services (MCLUES) conducted a water
quality study of Withers Cove of Lake Wylie. The MCLUES sample locations are presented on
Figure 1. Composite and grab samples collected by MCLUES were analyzed for several
inorganics including copper according to EPA Method 200.8. Based on the laboratory
analytical results, two water samples collected from near the apparent pump intake area within
Withers Cove and cooling spray pond discharge exhibited copper in concentrations above the
North Carolina Department of Environment and Natural Resources, Division of Water Quality,
Surface Water Quality Standard (NCAC 2B Standard) of 7.0 micrograms per liter (µg/L).
The filter back flush sample location is a trench within the pump house situated along the lake
shoreline west of the main plant facility. The cooling spray pond discharge is located south of
the plant facility on the western end of the pond (Figure 1), Photographs of the sampling
locations are presented in Appendix A. The sampling protocol is presented below.
SAMPLING PROTOCOL
Filter Back Flush Composite Sampling
Delta collected composite samples from the back flush trench (Appendix A, Photograph 1 and
2) within the pump house during the 15 minute daily back flush of the filters. Three 500
milliliter (mL) aliquots were collected at five-minute intervals 'over the 15-minute cycle. The
aliquots were then manually composited into a single composite sample. Composite samples
were collected daily from February 9, 2010 through February 12, 2010.
Cooling Spray Pond Discharge Composite Sampling
Delta used an ISCOa 3710C Compact Sampler placed at the cooling spray pond discharge to
collect composite samples over a 24-hour period (Appendix A, Photograph 3 and 4). The
sampler was programmed to collect 100mL aliquots once every hour into a 2.5-gallon
polyethylene bottle. The sampler was started on February 8, 2010 and composite samples
were collected daily beginning on February 9 through February 12, 2010. The samples
collected on February 9 and February 10 were not 24-hour composites because the battery
that powered the Compact Sampler lost voltage -due to cold overnight temperatures and the
sampler was unable to collect all of the scheduled aliquots. The composite sample collected
from February 9 consisted of 14 of the 24 scheduled aliquots and the composite sample
collected from February 10 consisted of 22 of the 24 scheduled aliquots. The battery was
replaced and the sampler collected all the aliquots scheduled from the remaining sample
dates.
The composite water samples collected from the filter back flush discharge and cooling spray
pond discharge were submitted to Pace Analytical Services, Inc. (Pace) of Huntersville, North
Carolina for analysis for total and dissolved copper using Inductively Coupled Plasma/Mass
Spectrometry (ICP/MS) according to EPA Method 6020. Pace filtered the dissolved composite
samples under laboratory conditions to remove any suspended sediments.
Water quality field parameters were collected while sampling at both locations to evaluate pH,
temperature, dissolved oxygen, specific conductivity, turbidity, total dissolved solids, and

oxidation reduction potential using a Horiba Model U-22 water quality meter. The Horiba was
calibrated each day prior to sample collection. The surface water sample field readings are
summarized in Table 1,
LABORATORY ANALYTICAL RESULTS
The laboratory analytical results of the samples collected by MCLUES and by Delta are
presented in Table 2 and are summarized below. The laboratory analytical reports and chain
of custody records for the water samples collected by Delta are contained in Appendix B.
MCLUES Samples
Composite water samples collected by MCLUES from July 2008 to July 2009 at location LW10
exhibited total copper concentrations ranging from 3.3 µg/L to 6A µg/L. Grab water samples
collected from locations identified as Upper, Middle, Lower, Intake, Intake Spillout, and Cooling
Pond exhibited total copper concentrations ranging from 3.1 pg/L to 9.9 pg/L. Concentrations
of total copper reported from three grab samples (Intake, Intake Spillout, and Cooling Pond)
exceeded the NCAC 2B Standard of 7.0 µg/L. No composite or grab water samples collected
by MCLUES were submitted to the laboratory (CMU-Environmental Laboratory Services) for
analysis of dissolved copper. The MCLUES sampling locations are presented en Figure 1.
Delta Samples - Cooling Spray Pond Discharge
The composite water samples collected from the cooling spray pond discharge exhibited total
copper concentrations ranging from 5.6 pg/L to 7.8 pg/L (an average concentration of 6.38
pg/L). Dissolved copper concentrations ranged from 3.7 pg/L to 5.6 pg/L (an average of 4.35
pg/L). Only the initial composite sample collected from the cooling spray pond discharge on
February 9, 2010 exhibited a total copper concentration of 7.8 mg/L, slightly above the NCAC
2B Standard. However, the dissolved copper concentration for the composite water sample
(5.6 �tg/L) was below the NCAC 213 Standard.
Delta Samples — Filter Back Flush Discharge
The composite water samples collected from the filter back flush discharge exhibited total
copper concentrations ranging from 4.6 pg/L to 9.1 pg/L (an average concentration of 5.88
pg/L). Dissolved copper concentrations ranged from 3.1 pg/L to 3.3 pg/L (an average of 3.13
pg/L). Only the initial composite sample collected from the filter back flush discharge on
February 9, 2010 exhibited a total copper concentration of 9.1 mg/L, slightly above the NCAC
2B Standard. However, the dissolved copper concentration for the composite water sample
(3.0 µg/L) was below the NCAC 213 Standard,
CONCLUSIONS
Only two of the eight composite water samples collected at the SEI site during the course of
this study, exhibited total copper concentrations slightly above the established NCAC 213
Standard of 7.0 �Lg/L. Both samples were collected on February 9, 2010, the first day samples
were collected for laboratory analysis. Based on a review of the field readings collected on
that day, pH measurements represented the lowest values reported during the sampling event

(i.e. more acidic) while turbidity values were the highest. In addition, dissolved copper
concentrations detected in the water samples collected on February 9; 2010, indicate that
suspended colloidal material (i.e. sediment, organic debris) was present in the water samples
and likely resulted in a "false positive" indication of copper impact.
Based on the laboratory analytical data, field measurements, and our conclusions, Delta does
not recommend conducting additional sampling or analytical testing at the water discharge
locations investigated as part of this study. It is not apparent that discharges from the cooling
spray pond and filter back flush are adversely impacting the water quality of Withers Cove of
Lake Wylie.

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 Requirements and Records. Secondary containment is
required for: bulk storage of liquid. materials; storage in any amount of Section
313 of Title III of the Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and storage in any amount of hazardous substances 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 directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices which shall be
secured closed with a locking mechanism, and any stormwater that accumulates in
the containment area shall be at a minimum visually observed for color, foam,
outfall staining, visible sheens and dry weather flow, prior to release of the
accumulated stormwater. Accumulated stormwater shall be released if found to
be uncontaminated by the material stored within the containment area. 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 (5) 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 the potential of pollutant sources to contribute
Part 11 Page 2 of 10

Permit No. NCS000021
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, an oil 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.
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 that 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 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
re -certification that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges.
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. Inspections of the facility and all stormwater systems shall
occur at a minimum on a semi-annual schedule, once during the first half of the year
(January through June) and once during the second half (July through December), with at
least 60-days separating inspection dates (unless performed more frequently). 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. These facility inspections are different from, and in addition to, the
stormwater discharge characteristic monitoring required in Part II of this permit.
9. Implementation. The permittee shall implement the Plan. 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 actions taken to

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
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours.

Permit No. NCS000021
During the term of this permit, if the sampling results exceed the benchmark value, or are outside
the benchmark range, for any specific parameter at any specific outfall on more than four
occasions, DWQ may:
• Require that the permittee increase or decrease the monitoring frequency for the
remainder of the permit;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stonmwater control measures; or
• require that the permittee implement site modifications to qualify for the No Exposure
Exclusion.
This site discharges to impaired waters experiencing problems with nutrients. If a Total
Maximum Daily Load (TMDL) is approved for this segment of Lake Wylie, the permittee may
be required to monitor'for the pollutant(s) of concern in the future and submit results to the
Division of Water Quality. The Division will consider the monitoring results in defermining
whether additional BMPs are needed to control the pollutant(s) of concern to the maximum
extent practicable.
If additional BMPs are needed to achieve the required level of control, the permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a timetable
for incorporation of those BMPs into the permitted Stormwater Pollution Prevention Plan.

then released oil to the surface waters of the spray pond on site. Discharge waters
from the spray pond carried the surface oil to Withers Cove on Lake Wylie where
it was contained. The substance released was identified as Mobil DTE Oil Light,
a light amber lubricating oil. The quantity of oil released is estimated to be 300
gallons
Document the presence of free „product (if known).
There was a visible sheen of oil on surface waters.

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 III, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
1. Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources that 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. The map
should identify whether each receiving water is impaired (on the state's 303(d)
List of impaired waters) or is located in a watershed for which a TMDL has
been established, and what the parameter(s) of concern are.
North Carolina's 303(d) List can be found here:

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 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:
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 Requirements and .Records. Secondary containment is
required for: bulk storage of liquid materials;'storage in any amount of Section
313 of Title III of the Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and storage in any amount of hazardous substances 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 directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices which shall be
secured closed with a locking mechanism, and any stormwater that accumulates in
the containment area shall be at a minimum visually observed for color, foam,
outfall staining, visible sheens and dry weather flow, prior to release of the
accumulated stormwater. Accumulated stormwater shall be released if found to
be uncontaminated by the material stored within the containment area. 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 (5) 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 the potential of pollutant sources to contribute
Part I I Page 2 of 10

Iq
y
Permit No. NCS00002 i
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, an oil 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.
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 that 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 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
re -certification that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges.
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.
Part II Page 3 of 10

Permit No. NCS000021
8. Facility Inspection Program. Inspections of the facility and all stormwater systems shall
occur at a minimum on a semi-annual schedule, once,during the first half of the year
(January through June) and once during the second half (July through December), with at
least 60-days separating inspection dates (unless. performed more frequently). 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. These facility inspections are different from, and in addition to, the
stormwater discharge characteristic monitoring required in Part II of this permit.
9. Implementation. The permittee shall implement the Plan. 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 actions 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

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
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours.

Permit No. NCS000021
During the term of this permit, if the sampling results exceed the benchmark value, or are outside
the benchmark range, for any specific parameter at any specific outfall on more than four
occasions, DWQ may:
• Require that the permittee increase or decrease the monitoring frequency for the
remainder of the permit;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures; or
• require that the permittee implement site modifications to qualify for the No Exposure
Exclusion.
This site discharges to impaired waters experiencing problems with nutrients. If a Total
Maximum Daily Load (TMDL) is approved for this segment of Lake Wylie, the permittee may
be required to monitor for the pollutant(s) of concern in the future and submit results to the
Division of Water Quality. The Division will consider the monitoring results in determining
whether additional BMPs are needed to control the pollutant(s) of concern to the maximum
extent practicable.
If additional BMPs are needed to achieve the required level of control, the permittee will be
required to (1) develop a,strategy for implementing appropriate BMPs, and (2) submit a timetable
for incorporation of those BMPs into the permitted Stormwater Pollution Prevention Plan. '

Renewal Application with Proposed Modification
Dear Mr. Patterson:
FEB t s 2008
NR - WATE Wt);Y1
By this letter, Siemens Power Generation Inc. requests modification to the NPDES Permit
number NCS000021, renewal application for coverage, submitted to the Division of Water
Quality on March 30, 2004.
Specifically, Siemens Power Generation requests that the sampling location identified as outfall
008 be removed from current permit application. The reason for this request is as follows:
Mr. Michael Parker, representing the North Carolina Division of Water Quality, conducted an
on site Compliance Evaluation Inspection of the Charlotte Turbine /Generator facilities on
January 15, 2008 During that inspection, the area represented by outfalls 007 and 008 was
discussed and reviewed with Mr. Parker for possible duplication of stormwater flow thus the
possible elimination of outfall 008.
As a result of our review, and Mr. Parker's concurrence, it was concluded that outfalls 007 and
outfall 008 had substantially identical stormwater discharges, and we believe the area
representing both owfalls would be well represented by outfall 4 007 alone, thus reducing the
number of outfalls being sampled.
Asper your instructions during our conversation of Thursday morning, February 14, 2008, this
request for permit modification addresses only the elimination of outfall 008 from our permit
application, therefore, no additional forms are attached
If you have any questions or need additional information with regard to this matter, please do
not hesitate to call me. My phone number is [phone]

Dear Mr. Pickle:

This letter is in reference to the stormwater permit for the Siemens Turbine Generator Plant,
Located in Charlotte North Carolina. On March 30, 2004 Siemens Power Generation Inc.
submitted to the Division of Water Quality the renewal application to discharge stormwater to the
receiving waters designated as Lake Wylie in the Catawba River Basin.
The current stormwater permit on record far the Turbine Generator facilities issued by your
department became effective October 1, 1999 with an expiration. date of September 30, 2004.
On March 30, 2004 Siemens Power Generation Submitted to the Division of Water Quality the
completed renewal permit application to discharge stormwater under the National Discharge
Elimination System, and with the resulting backlog of permit applications, Siemens Power
Generation was not issued a renewal permitfrom the Division of Water Quality at the expiration
period of our current permit.
Based upon the conversations with your office, it is our understanding that the Stormwater permit
issued to the Siemens Turbine Generator plant in October, 1999 will continue in effect until a new
stormwater permit has been issued by your department.
In addition, as discussed in a recent conversations with your office concerning the Sampling
Monitoring Schedule for the Charlotte Turbine Generator Plant, Siemens Power Generation had
unintentionally missed the first two quarters of the fourth year permit term monitoring schedule,
and requested guidance on what procedures Siemens should fallow to correct this deficiency.
It is our understanding as a result of this conversation, Siemens will continue to sample the
remaining representative storm event as outlined in Section B of the monitoring schedule, and in
addition, will sample representative storm events of the first two quarters of the fifth year of the
permit term.

Siemens Power Generation requests conformation from the Division of Water Quality, in writing,
that the revised monitoring schedule outlined above is acceptable.

this matter.

The Division of Water Quality (Division) has reviewed a petition submitted on behalf of Siemens
Westinghouse by Mr. Senne C. Hutson, Smith Helms, MuIliss & Moore, L.L.P The petition proposed to
replace sampling at one outfall with sampling at three upstream outfalls at the subject facility. The
subject facility is located at 5101 Westinghouse Boulevard in Charlotte, North Carolina.
The specific request was to allow "Outfall 001" (as designated on the submitted site plan) to be replaced
by three new outfalls, designated as "Outfall 006", "Outfall 007", and "Outfall 008". After reviewing the
submitted documentation, it is clear to the Division that samples from the new outfalls would be more
representative of the stormwater runoff from the subject area than the previously used sample point
located at the outlet of the spray pond. Therefore, the Division agrees with the petition and grants the
request to sample at the three new outfalls

Re: Siemens-Westinghouse/Charlotte Facility -- Stormwater Permit
Dear Brian, Bradley and Darren:
At our meeting on January 21 and in my letter to you dated January 31, I advised that
Siemens -Westinghouse would be working with its consultant, S&ME, to identify sampling outfalls
to replace outfall no. 1. That work has now been completed.
Siemens -Westinghouse proposes to replace outfall no. 1 with three new outfalls, numbered
6, 7 and 8. Enclosed is a map prepared by S&ME which shows the following:
1. The respective locations of new outfalls 6, 7 and 8.
2. The drainage area served by each outfall. The area served by outfall no. 6 is bordered
in red. Outfall no. 7 is bordered in green and outfall no. 8 in brown.
3. The drainage flow direction within each of these drainage areas.
4. The sub -area type and industrial activities taking place in each area. This
information is provided in the legend to the map.

Mr. Brian McGinn
Mr. Bradley Bennett
Mr. Darren England
February 23, 2000
Page 2
Siemens -Westinghouse has confirmed that representative samples can be collected from each of the
proposed new outfalls.
I trust this provides all of the information you need to issue the letter approving this change
in outfalls as a minor modification to our new permit. Once we receive this letter, we will dismiss
the pending contested case petition with prejudice. That case is still scheduled to begin on March
7. Hopefully you can reach a final decision prior to that time.
If you have any questions or issues that we need to discuss regarding this matter, please let
me know right away. I look forward to hearing from you soon.
Sincerely,
Smith Helms Mulliss & Moore, L.L.P.

Re: Siemens-Westinghouse/Charlotte Facility -- Stormwater Permit
Dear Brian, Bradley and Darren:
BALE
WILM
: OFFICES
TA
On behalf of Siemens -Westinghouse, I want to thank you for taking the time to meet with
us on January 21 (which was only four winter storms ago!) We felt it was a very productive meeting
and hope you share that feeling.
With regard to the proposed deletion of outfall no. 1 from the permit and the inclusion of two
new sampling locations, we will prepare information delineating the areas of the Siemens -
Westinghouse Charlotte facility that feed each of these new locations and identifying the activities
that take place within these areas (such as parking, material storage, runoff from roofs, etc.) We will
also provide an explanation as to how these two new locations taken in combination with all of the
other sampling locations results in Siemens -Westinghouse being able to monitor the effects all of
the activities -at its Charlotte facility have on stormwater discharges. We understand no information
is needed regarding the construction specifications of the new sampling points other than a statement
that we have determined that representative samples can be collected at each of these points.
Once that information is available, we will submit it to you in the form of a request for a
minor permit modification. If the information is acceptable to and sufficient for you, our request to

Mr. Brian McGinn
Mr. Bradley Bennett
Mr. Darren England
January 31, 2000
Page 2
delete outfall no. 1 and include the two new locations will be approved in writing by you. We
understand that since this is a minor modification, no form of permit application or use of other
standard form is necessary to initiate this change. If this is not the case, please let us know what
format or forms should be used.
We hope to have this information to you in the next two to four weeks. Obviously the
weather has wreaked havoc with getting this work started before now. I spoke this afternoon with
the plant's environmental manager who in turn was going to contact our outside engineering firm
today to advise them of the work to be done. As this schedule puts us past various deadlines and
other dates established by the Office of Administrative Hearings with regard to the pending
contested case petition, I will work with Brian to notify the ALJ of our progress towards settlement
and the need for an extension of those deadlines in order to complete the settlement.
As to the increased monitoring requirements, we understand from our meeting that the State
concluded that additional data points were needed beyond the two established by the previous permit
in order to effectively manage various aspects of the overall stormwater discharge program. Even
though the cutoff concentrations are not and have never been enforceable permit limits and are not
included in the draft permit, we understand that those cutoff concentrations still exist and are still
considered by the State in evaluating various situations. As to the specific compounds Siemens
Westinghouse monitors (oil and grease and TSS), the cutoff concentrations have not changed and
that we can still compare our sampling results to those concentrations to determine if our results are
within an acceptable range.
We further understand that the possibility exists that the increased amount of data generated
may possibly lead to future permits that do not require the same amount of or any quantitative
sampling. We recognize that there is no guarantee of such a result and that a number of factors both
specific to our site as well as generally applicable to various parts of the stormwater program will
go into the State's analysis of that issue.

Once again, thank you for taking the time to meet with us. If there is anything in this letter
that is incorrect or not stated which is material in any way, please let me know right away. We look
forward to bringing this matter to a mutually acceptable resolution.

Smith Helms Mulliss & Moore, L.L.P.

WRITER'S EMAIL ADDRESS
Be n n e_H u is on Q S HM M. CO M
We represent Siemens Westinghouse with regard to this proposed NPDES stormwater
permit. By this letter, we are requesting two changes to this permit.
1. Deletion of Outfall No. 1 from Permit
First, Siemens Westinghouse requests that outfall no. 1 be deleted from this permit for all
purposes. The reason for this request is simple. Due to the boom in commercial real estate
development in the area where the Siemens Westinghouse plant is located, the stormwater discharge
at outfall no. 1 consists of discharges from a number of neighboring properties and is no longer
representative of a discharge solely from our facility.
Outfall no. 1 is located at the southern end of a spray pond that Siemens Westinghouse
constructed in 1968 to handle the discharge of non -contact cooling water from the manufacturing
plant also being built then. At that time, there was no other development or use of any of the
properties neighboring or in the vicinity of the plant. After operations began at the plant, the only
discharges to the pond were non -contact cooling water from manufacturing operations,
stormwater runoff from that portion of the plant that drained to the pond and stormwater
runoff from the surrounding area that naturally drained to the location where the pond had
been built. As the surrounding area was undeveloped, percolation into the soil, absorption
by plant life and other natural processes limited the amount of stormwater from other
L
properties that reached the pond.

That is not the case today. The pattern of development has changed significantly since the
plant's previous permit took effect on October 1, 1994. A number of properties fronting or
accessible from Westinghouse Boulevard within a mile of the plant have been developed for a
variety of commercial and industrial uses. To allow for this development, the City of Charlotte
installed a 54-inch storm sewer which discharges to the northern end of Siemens Westinghouse's
spray pond. Indeed, the discharge point for this sewer is located right at the Siemens
Westinghouse's property boundary less than 20 feet from the northern end of the spray pond.
In addition, on the property next to the plant immediately to the east, General Motors has
built a parts distribution facility over 352,000 square feet in size with most of the rest of the site
paved for vehicle traffic and outside storage. The construction includes a stormwater retention basin
which is located directly along the eastern boundary of the Siemens Westinghouse property and
drains directly into the spray pond.
Siemens Westinghouse has control over and has developed plans to manage its stormwater
discharge into the spray pond. However, it has no such control or even the ability to influence the
discharges coming from the neighboring General Motors facility or'from the City's storm sewer line.
Nevertheless, if those discharges cause a violation of the proposed permit, Siemens Westinghouse
will be responsible, not the neighboring property owners. Such violations will not only subject
Siemens Westinghouse to possible enforcement action by the State but also to citizen suits under the
Clean Water Act by the downstream residents on Lake Wylie. Furthermore, any violations would
no doubt result in stricter standards in any future permits which standards would once again only
apply to Siemens Westinghouse.
Indeed, because of this situation, as the proposed permit is currently written, Siemens
Westinghouse would not be able to comply with it as of the first day it takes effect. Part II, Section
A. L(e) requires Siemens Westinghouse to provide a "Certification that the stormwater outfalls have
been evaluated for the presence of non-stormwater discharges" with such certification to be made
"under penalty of law." As you can no doubt appreciate, with the number of off -site discharges now
entering the spray pond, Siemens Westinghouse as a corporation and any of its responsible corporate
officers individually cannot assume and should not be required to assume the risks associated with
such a certification in these circumstances.
If outfall no. 1 is removed from the requirements of this permit, the concerns expressed in
this letter would be resolved. Siemens Westinghouse will continue to comply with regulatory and
permit requirements for its other four outfalls. At those locations, discharges consist of stormwater
runoff from the plant and not any neighboring properties.

2. Inclusion of Sampling Requirements from Previous Permit and Draft Renewal
Permit
Siemens Westinghouse's current permit requires analytical monitoring for specific
stormwater discharge characteristics on an annual basis during each year the permit is in effect.
However, if the results during the first year of sampling are below certain cut-off concentrations, no
further analytical sampling needs to be conducted until the last year of the permit. Sampling
conducted in the first year of the curent permit showed levels below the cut-off concentrations so
Siemens Westinghouse did have to conduct any further sampling until earlier this year. The draft
renewal permit issued in August of this year contained identical provisions.
The proposed new permit, however, contains a different provision. Pursuant to Part 11,
Section B, analytical monitoring now is to be conducted each quarter during the fourth year of the
permit. As a result of this change, the amount of sampling events Siemens Westinghouse will have
to conduct (along with the attendant time and cost involved) is twice what it had to do under its
current permit.
Furthermore, the proposed permit has eliminated cutoff concentrations: With the removal
of cut-off concentrations, the permit has no quantitative indicators that Siemens Westinghouse can
refer to in order to determine whether or not the quality of the discharge is acceptable.
We are concerned that this will leave Siemens Westinghouse and other permittees "in the
dark" as to the significance of its sampling results. With cut-off concentrations, a permittee had
some assurance that if its results were below those concentrations, the quality of its discharge was
acceptable. Under the proposed permit, it appears that the results will be submitted to the State
which will consider them in determining what the provisions of the renewal permit should be. When
the State issues the draft renewal permit towards the end of the fifth year (nearly a year after the last
samples were taken and nearly two years aver the first sampling event in the fourth year), the
permittee wilI learn for the first time whether or not its sampling results were a problem. Even then,
the permittee will likely only see that the conditions of its permit are more restrictive without any
explanation as to why.
We need a fuller explanation of the "revised ... monitoring strategy" referred to in the cover
letter transmitting the permit to determine if our concerns in this regard are well founded.
Specifically, we need to know why the amount of required sampling events was doubled and how
the permittee will be advised as to whether or not the State considers its sampling results to be a
problem.
I do want you to be aware that our deadline for filing a petition for contested case as to this
proposed permit is October 23. In order to preserve our legal rights, if we have not resolved our
issues by that time, we will need to file a petition. Please do not take such a filing as an indication

Westinghouse would like to r�solt a th'e ma$ers on an informal basis, a sentiment I know the State
shares. ��. ..�I
