CWIS and Non -Contact Cooling Water NPDES Permits January 2015
,o,
1.0 INTRODUCTION
The Siemens Energy Turbine Generator Service Center facility, located at 5101
Westinghouse Boulevard in Charlotte, North Carolina, withdraws cooling water from Lake
(New
Wylie at an average rate of approximately 7.5 million gallons per day. Two components of
the cooling water operations will be covered under general permits enforced by the State of
North Carolina Department of Environment and Natural Resources (NCDENR) Division of
Water Quality (DWQ). The first component is for Non -Contact Cooling Water Discharge
under an existing National Pollutant Discharge Elimination System (NPDES) General
Permit. The second component is for the Cooling Water Intake Structure which will also be
covered under a General Permit. However, the DWQ has not completed the permitting
procedures for the Cooling Water Intake Structure. It is assumed both components will be
covered under the existing General Permit for Non -Contact Cooling Water Discharge.
The cooling water withdrawal intake tower is located in Lake Wylie at Withers Cove, on the
Catawba River (see Drawing 1 in the Figures section of this document). The non -contact
cooling waters discharge from the facility to a 14-acre Spray Pond located southeast of the
facility. From the Spray Pond, the cooling waters discharge through a riser to a stream that
flows approximately 1,200 feet to Lake Wylie.
1.1 Cooling Water Intake Structure Permit
The Cooling Water Intake Structure (CWIS) Permit is a new requirement from the federal
�►
Clean Water Act's Section 316(b). The intent of the permit is to regulate the CWIS of each
facility that withdraws more than 2 million gallons per day of water of which at least 25
percent is used for cooling water. The regulations are designed to protect fish and other
aquatic life from impingement (being pinned against cooling water intake structures) and
entrainment (being drawn into cooling water systems and affected by heat, chemicals or
physical stress).
For impingement mortality control, EPA proposes two potential compliance approaches:
(1) Install modified traveling screens equipped with fish buckets, a low-pressure wash
and a fish handling and return system, or
(2) Reduce through -screen velocity to 0.5 feet per second or less.
„■, For entrainment control, EPA proposes maintaining screen openings of 0.56 inches or less.
1.2 Non -Contact Cooling Water Discharge Permit
The Siemens facility presently operates under the General Permit No. NCG500000 to
"Discharge Non -Contact Cooling Water, Cooling Tower and Boiler Blowdown,
Condensate, Exempt Stormwater, Cooling Waters Associated with Hydroelectric
Operations, and Similar Wastewater Under the National Pollution Discharge Elimination
System. " The specific permit number is NCG500175, issued 8/1/2012 and scheduled to
expire 7/31/2015. According to NCDENR web page for Wastewater NPDES permits the
renewal application is due by February 1, 2015. The previous renewal application form
identified three discharge points for the non -contact cooling water; OF-001, OF-002 and
OF-003.

3.1 Source Water Physical Data
40 CFR 122.21(r) (2) specifies the following information:
A description and scaled drawings showing the physical configuration of the water
body, including areal dimensions, depths, and temperature regimes, identification
F•, and characterization of the source hydrological and geomorphological features,
estimate the intake's area of influence within the waterbody and locational maps.
1014 The water source is Lake Wylie. According to Duke Energy's web pager, the lake's dam,
first created in 1904 near Fort Mill, South Carolina, was rebuilt in 1924 and the lake's
surface expanded to approximately 13,443 acres and 325 miles of shoreline. In addition to
CA supporting Wylie Hydroelectric Station, Lake Wylie also supports Allen Steam Station and
Catawba Nuclear Station with cooling water and provides water supply for Belmont and
Rock Hill. Full pond elevation at Lake Wylie is approximately 569.4 feet. Full pond is the
0k, level of the reservoir that corresponds to the point at which water would first begin to spill
from the reservoir's dam; the crest of the spillway. The Annual Normal Operating Range
for the lake in 2014 has a minimum elevation of 563.4 and a maximum of 569.4. The
MR average water level for Lake Wylie, based on daily readings over the last 12 months, was
567.0.
Water temperatures in the lake at the Cooling Water Intake Structure vary seasonally as
shown in the chart below for 2014.

.. Originally, Siemens tested their turbines with steam. Now they test the turbines using a
vacuum system. As a consequence, the amount of water withdrawal required was
significantly reduced. Pump 3 was taken out of commission and removed from the pump
.. house.
3.3 Source Water Baseline Biological Characterization Data
40 CFR 122.21(r) (4) specifies the following information:
A description of the biological community in the vicinity of the cooling water intake
structure.
Lake Wylie is the third largest reservoir in the Catawba-Wateree system and is located
southwest of Charlotte in Gaston and Mecklenburg Counties, North Carolina and York
.. County, South Carolinaz.
A review of rare, threatened, and endangered species known to occur within the three
., surrounding counties of Lake Wylie (Gaston, Mecklenburg and York), revealed two
vertebrate species; the American eel (Anguilla rostrata) and Carolina darter (Etheostoma
collis collis). Both species are listed as federal species of concern (FSC). FSC is an
informal term. It is not defined in the federal Endangered Species Act. In North Carolina,
the Asheville and Raleigh Field Offices of the US Fish and Wildlife Service (Service)
define Federal Species of Concern as those species that appear to be in decline or otherwise
.. in need of conservation and are under consideration for listing or for which there is
insufficient information to support listing at this time. Subsumed under the term "FSC" are
all species petitioned by outside parties and other selected focal species identified in Service
.. strategic plans, State Wildlife Action Plans, or Natural Heritage Program Lists 3.
The Carolina Darter inhabits small- to moderate -sized streams in areas of low current

velocity. Habitat substrates preferred by this species are usually characterized by mud,
.. sand, and sometimes bedrock. This darter seems to be tolerant of fine sediments covering
the substrate it inhabits. The Carolina Darter exists only in the Piedmont region from south-
central Virginia through North Carolina into north -central South Carolina. The range in
., South Carolina is restricted to the Santee River Basin4.
The American eel is a catadromous species that spawns in the Atlantic Ocean. This species
.. is more common near the sea rather than inland streams and lakes. The American eel lives
in freshwater as adults, usually in larger rivers or lakes, primarily swimming near the
bottom in search of food. The species prefers to hunt at night and resides in crevices or
,., other shelter from the light during the day, often times burying themselves in the substrate,
whether mud, sand or gravels.
am A list of common sports fish that inhabit Lake Wylie can be obtained by visiting the South
Carolina Department of Natural Resources website6. A request for additional wildlife, fish
and habitat information collected by Duke Energy was requested on January 9, 2015. A
,N response from Duke Energy was received on January 16, 2015 that the Water Resources
group within Duke Energy would be able to provide additional information. However, as of
this date, the additional data has not been received.
.. 3.4 Cooling Water System Data
40 CFR 122.21(r) (5) specifies the following information:
OR The operation of the cooling water system including descriptions of reductions in
water withdrawals, recycled water, proportion of the source water body withdrawn.
.R The Non -Contact Cooling Water is screened and pumped from the Pump House to the
Powerhouse and passes through the condensers of Chiller #2 and #3, then discharges to the
Spray Pond. Pumping records for cooling water withdrawal and return to Lake Wylie for
2013 is summarized in Table 2. With the reported average water withdrawal of 7,547,066
gallons per day and the pumps operating 24/7, the pumping rate is 5,241 gallons/minute

40 CFR 122.21(r) (6) specifies the following information:
A description of how the impingement mortality will be addressed, such as intake
screen modifications or flow reductions.
EPA specifies that impingement mortality can be addressed by installing modified traveling
screens equipped with fish buckets or reducing through -screen velocities to 0.5 feet per
second or less. Based on the design drawings (Figure 3), the Lake Levels, and the pumping
r rates, the screen velocity calculations are shown in Table 3.

The temperature limit for fresh water is 2.8°C above natural water temperature. However,
�► the receiving water temperature in no case should exceed 32°C at the downstream
monitoring location for lower piedmont waters.
Since no chlorine is present in the discharge, TRC monitoring is not required. Oil and
Grease monitoring is not required because the cooling water does not contain any air
compressor condensate. Likewise, no water treatment or chemical additives are added so

4.2 Sampling Locations
Figure 1 shows the seven cooling water sampling locations. The water is sampled at the
pump house (1) when taken from Lake Wylie [Photo 1]. After it is used for cooling in the
plant, it is sampled just before discharging into the Spray Pond (2) [Photo 6]. As the water
flows from the Spray Pond principal spillway conduit (3) [Photo9] it is sampled before
entering the surface stream which flows back to Lake Wylie. When the water re-enters
Lake Wylie it is sampled at the dock at Cove Center (4) [Photo 10]. Some HVAC runoff is

discharged from the plant at two locations identified as Outfalls OF-002 (5) [Photo I l ] and
.. OF-003 (6) [Photo 121 which are also sampling points. Finally, when the runoff ditches
from OF-002 and OF-003 combine and flow through a culvert under the pump house road
to re-enter Lake Wylie, the flows are sampled (7) [Photo 121. Table 5 summarizes the
locations.

REF.: Change in Outfall 002 & 003 Locations, NCG500175
Dear Sir:
This letter serves as notification of the change in location of Outfalls 002 and 003 as self
identified under our Stormwater and Wastewater NPDES permits. These moves are a result of
the construction and regrading associated with our new manufacturing facilities. Neither the
receiving water point of entry into Withers Cove or the process/stormwater entering these outfalls
has changed.
Please call or email if further clarification is required.

corporation to do business in North Carolina. Although it's only a name change this is the legal
document for that change. I hope this is helpful and please fill out the NC NPDES Name and/or

process. I will need you to mail the original.documents and form as per direction. It was nice talking

POIig SOURCE BRANCH
Westinghouse Electric Corporation submitted an October 15, 1997 letter (see attached) that described
a planned corporate restructuring that was to involve separation of its industrial operations from its
media -related operations. This letter serves as notification that the separation will not be occurring.
However, Westinghouse has instituted a name change that became effective December 1, 1997. The
Westinghouse Electric Corporation has formally changed its name to `CBS Corporation'. CBS
Corporation has retained Westinghouse's 1872 Pennsylvania charter of incorporation.
Also, please be advised that CBS Corporation will be divesting the Westinghouse Power Generation
business unit, the operator of the subject facility, in 1998. The new owner of Power Generation will be
Siemens AG. Prior to the transfer of ownership to Siemens, the Power Generation business unit will
continue to be operated under the Westinghouse name as a `Discontinued Operation' of CBS
Corporation. There will be no immediate change in the day-to-day operation of the facility and the
referenced certificate will be held by CBS Corporation doing business as Westinghouse Electric
Corporation.
In a subsequent letter we will inform you of the completion of the divestiture to Siemens and request a
transfer of the referenced certificate. In the interim, if you have any questions or require additional
information, please call Mr. Thomas Tuori at [phone].

Dear Mr. Clark:
11 Stanwix Street
Pittsburgh Pemsylvaia 15M.1384
The purpose of this letter is to inform you that Westinghouse Electric Corporation is planning to separate its
industrial operations from its media -related businesses in late November 1997. At that time, Westinghouse will
effect a series of asset and stock transfers and liability assumptions among itself and its subsidiaries. The separation
will have no effect on the day -today operations at the subject facility. Ile new industrial company will be named
Westinghouse Electric Corporation, a 1997 Pennsylvania corporation with Federal Taxpayer ID number 23-
2914866. The media company will be named CBS Corporation, an 1872 Pennsylvania corporation with Federal
Taxpayer ID number 25-0877540.
The subject certificate of coverage will be held by the new industrial company, Westinghouse Electric Corporation.
Please accept this letter as notification of the above mentioned separation and as our application to transfer the
certificate of coverage. We will assume that the transfer will be effectuated as of the separation date unless
otherwise advised. We will let you know, through a subsequent letter, of the effective date when the industrial
operations are separated from the media -related businesses.
In the interim, if you have any questions or require additional information, please call Mr. Thomas Tuori at (412)

MEMORANDUM
To: Bradley Bennett
Stormwater & General Permits Unit
From: Charles H. Weaver
N PD ES Unit
Subject: General Permit status
NCG500175 -Westinghouse
Mecklenburg County
Bradley, Westinghouse submitted a very detailed renewal application as well as a
letter asking for future consideration from the Division in regard to this
discharge. The collection pond for the non -contact cooling water at this facility
has stormwater discharges emptying into it. Westinghouse is understandably
concerned that pollutants which might enter the pond via the stormwater outfalls
could cause the discharge to violate the effluent limits in General Permit
NCG500000.
I sent the permit renewal out and spoke with Robert Carpenter (the facility
contact). I told him a response letter addressing his concerns would be
forwarded by the Division after the reorganization had been completed. Dave
and I talked this one over and we agreed that your Unit would be better
equipped to respond to the stormwater concerns.
I've attached the cover letter from the renewal application to this memo. The
rest of the application fills 3 file folders - it's in my office with the rest of the
NCG500 tiles. Have a look at this and proceed as you see fit.
Thanks for your help with this. If you have any questions, talk with me (or
Dave).

Dear Ms. Sullins:
Westinghouse Electric Corporation, Charlotte Turbine/Generator Plant, hereby requests
renewal of its existing National Pollutant Discharge Elimination System (NPDES) Permit
to discharge its non -contact cooling water to the receiving waters of Lake Wylie, of the
Catawba River Basin.
Enclosed is the permit application completed and signed by an authorized officer of the
corporation along with our corporate draft in the amount of four hundred dollars
($400.00) the required processing fee.

0
Page 2
Ms. Sullins
January 20, 1997
As outlined in our current permit, the effluent waters discharged by Westinghouse to lake
Wylie are exclusively non -contact cooling and receive no chemical treatment, therefore,
as instructed by your office, Westinghouse is exempted from the priority pollutant
analysis as part of this permit renewal application.
Westinghouse had previously notified your office that additional discharges not
emanating from or controlled by the Westinghouse Turbine Generator Plant appeared to
be entering the Westinghouse spray pond upstream of outfall 001. Drawing MS 2000
indicates the locations of these discharges in relation to the Westinghouse spray pond.
Earlier communications with your office, we pointed out that these other discharge
sources may have the potential to influence Westinghouse's permitted outfall 001.
The discharges appear to be from storm water runoff from new construction and
industrial activities in the area. We understand that your office has issued permits for
these discharges, with outfalls into the Westinghouse spray pond.
As part of our Renewal Application, Westinghouse below outlines its concern regarding
1
the additional discharges entering our spray pond from off -site sources. =>>
As our permit indicated, the Westinghouse discharge to the spray pond, consisting of only
non -contact cooling water, has not been problematic and Westinghouse has at its own
expense sampled the non -Westinghouse discharges at their point of entry into the spray
pond.
These analyses of the Westinghouse outfall confirm that, consistent with results of
present and past sampling, Westinghouse's discharges conform to regulatory
requirements. Obviously, we are concerned that this situation may change over time, as
the new discharges over which we have no control continue into our pond. Although
these discharges may not present a problem now, at some point these may negatively
impact the water at outfall 001, which to this point has consistently tested to be well
within applicable standards. Westinghouse does not believe it should be responsible for
such a situation.
Westinghouse thus requests some reassurance from your office, which we understand has
issued permits for these new discharges, that we will not be prejudiced under our renewed
permit because of these sources, and the potential that these sources may contain
regulated pollutants which Westinghouse does not discharge. Westinghouse should not

Page 3
Ms. Sullins
January 20, 1997
be held responsible for, not should it be penalized, if, for example, additional testing or
monitoring is required because of these new discharges or if the new discharges cause
exceedance of Westinghouse's permit.
Please make note that Mr. George Dann is no longer the plant manager for the Charlotte
Plant. Mr. Anthony R. Giof xedi has now assumed the position of plant manager. Please
direct all future correspondence to either his attention, or to Mr. Robert Carpenter,
Facility contact.
We request that your renewal of our permit reflect these considerations.
If you require additional information or have questions or comments concerning this
application. Please call me at 704-551-5149.

PART IV - EVALUATION AND RECOMMENDATIONS
The Permittee, Westinghouse Electric Corporation, has applied
for permit renewal. The subject NPDES Permit serves the Charlotte
Turbine/Generator Plant.
There are three discharges, all of which are non -contact
cooling water. Water is pumped from Lake Wylie and discharged
through the three discharges. All three discharge locations are
above the facilities water intake. All domestic and industrial
process wastewater is pumped to the CMUD collection system.
