Re :
Provisional Variance From Special Condition 4
of NPDES Permit IL0036919
The Illinois Environmental Protection Agency (Agency) has completed its technical review of
the attached provisional variance request submitted by Exelon Generation Company, L .L.C .
Clinton Nuclear Power Station (Exelon's Clinton Station) on September 6, 2005 (Attachment A)
.
Based on the review, the Agency GRANTS a provisional variance subject to specific conditions
set forth below for a period of 30 days beginning the date Exelon's Clinton Station reaches its
permitted 90-day temperature limit provided in Special Condition 4 of NPDES Permit
IL0036919 (Attachment B) .
Exelon's Clinton Station is a nuclear-fueled steam electric generating facility located in DeWitt
County, Illinois approximately six miles east of Clinton, Illinois
.
Heat from Exelon's Clinton Station is dissipated by means of a 5,000 acre cooling lake known as
Clinton Lake. The lake is a U-shaped impoundment that was formed by the damming of Salt
Creek and the North Fork of Salt Creek . The plant's intake structure is on the North Fork of Salt
Creek, and the outfall structure is located at the end of the discharge flume on the main branch of
Salt Creek. Average lake travel from the intake to the outfall is approximately eleven miles and
takes about 22 days .
Exelon's Clinton Station seeks a variance from Special Condition 4 of NPDES IL0036919 .
Special Condition 4 states in pertinent part
:
In accordance with IPCB order PCB 92-142, the temperature of the discharge to Clinton
Lake from Clinton Power Station, as measured at the second drop structure of the
discharge flume, shall be limited to a daily average temperature which (1) does not
exceed 99 degrees Fahrenheit during more than 90 days in a fixed calendar year running
from January 1, through December 31, and (2) does not exceed 110 .7 degrees Fahrenheit
for any given day.
Exelon's Clinton Station is seeking a provisional variance due to the extreme weather conditions
that have occurred during the summer of 2005 . Petitioner states that for the period from June 1
through August 31, the average temperature was 3 .1 degrees Fahrenheit warmer than the average
and 6.1 degrees Fahrenheit above the temperature of the same period a year ago . In addition,
Petitioner states that as of August 25, 2005, the precipitation in Northwest, Northeast and Central
Illinois is the third lowest on record . Petitioner explains that these unusually hot, humid and
drought conditions have resulted in the need for Exelon's Clinton Station to increase the number
of currently permitted days
(i.e., 90) during which the daily average discharge temperature to
Clinton Lake may exceed 99 degrees Fahrenheit
.
The most current short and long-range weather forecasts indicate a continuation of above
average temperatures and below average precipitation in the Central Illinois area .
The temperature of Excelon's Clinton Station's discharge to Clinton Lake is a function of outside
air temperature, intake temperatures, and power plant levels. When the outside air temperature
causes the daily average discharge temperature to exceed 90 degrees Fahrenheit, there is also a
high demand on the electrical grid. As Excelon's Clinton Station reduces power to control
discharge temperature below 99 degrees Fahrenheit, its ability to support system voltage is
diminished .
To ensure the reliability of the electrical grid in this part of the state, Excelon's Clinton Station
must maintain a specific voltage level . It can maintain this voltage level as long as it does not
reduce real load below 1062 megawatts . Under current and foreseeable weather and drought
conditions, however, even if Excelon's Clinton Station maintains a real load of 1062 megawatts,
it may still cause daily average discharge temperatures to exceed 99 degrees Fahrenheit
.
Granting the requested provisional variance will enable Excelon's Clinton Station to continue to
maintain power grid voltage in the service territory. If Excelon's Clinton Station is not able
maintain power grid voltage, there is an increased risk that the energy needs of its customers will
not be met. Moreover, depending on the operating status of other generating station's in the
area, Excelon's Clinton Station's continued operation may be essential for voltage support for
the Commonwealth Edison Company and Ameren IP Transmission systems
.
The Agency has reviewed the requested provisional variance and has concluded the following
:
1
.
The environmental impact from the requested relief is predicted to be minimal
;
conditions in the lake will be closely monitored and the Agency will be
immediately notified of any impact along with actions taken to remedy the
situation ;
2 .
No other reasonable alternatives appear available
;
3
.
No public water supplies will be affected ;

(3)
(5)
(7)

Excelon's Clinton Station will face an arbitrary and unreasonable hardship
if the request is not granted
.
The Agency hereby Grants the Excelon's Clinton Station a provisional variance from Special
Condition 4 of NPDES Permit IL0036919 as follows
:
Exelon's Clinton Station is granted 30 additional days to the 90 days specified in
Special Condition 4 of NPDES Permit IL0036919

September 6, 2005
Based on a discussion with Roger Callaway of your staff, John Petro, and Dave Siebert of
Exelon on 09/06/05, this correspondence is a revision of the Provisional Variance Request
dated September 1, 2005 . The reason for the revision is to increase the number of days
from 14 to 30 for days > 99°F. Based on continuing temperatures in the 80°F and drought
conditions, it is possible that there would be no reduction in lake temperatures through
September.
Exelon Generation Company, LLC ("Exelon") hereby requests that a provisional variance be
granted for its Clinton Power Station ("Clinton" or "Station") as provided for by Title IX,
Section 35, Subsection (b) of the Illinois Environmental Protection Act ("Act") . Specifically,
Exelon requests 30 additional days during which Clinton will be allowed to average above
99°F from the Station via outfall 002, the discharge flume . Based on the current heat and
extreme drought conditions and weather forecasts for the remainder of August and into early
September, Clinton Station will reach its permitted 90 days when discharge temperatures
have averaged above 99°F on or about September 11, 2005 .
Station Description
The Clinton Power Station is located in Dewitt County, Illinois approximately 6 miles east of
Clinton, Illinois and 60 miles northeast of Springfield, Illinois . The Station is a single unit
1090 MW nuclear-fueled electric generating station that began operating in 1987 .
The Clinton cooling lake was constructed for the purpose of providing condenser cooling
water and potable water. The lake consists of approximately 5,000 surface acres resulting
from the damming of two streams, i.e., Salt Creek and the North Fork of Salt Creek .
Condenser cooling water for the station is withdrawn from the North Fork Salt Creek leg of
Clinton Power Station
0-602361
Page 2
Clinton Lake by means of three circulating water pumps
.
The plant intake structure is on the
North Fork of Salt Creek approximately three miles upstream of the dam
.
The outfall
structure is at a point 3 .4 miles from the plant. The outfall structure (NPDES Permit Outfall
002) is located at the end of the discharge flume on the main branch of Salt Creek
. At a
cooling lake normal pool elevation of 690.0, the lake travel from outfall to intake is
approximately 11 miles with a corresponding travel time of 22 days .
This portion of the lake
is known as the cooling loop .
Relief Requested
The NPDES Permit for Clinton Power Station (IL0036919) provides limitations for thermal
discharges from the station via outfall 002, the discharge flume
.
Specifically, Special
Condition 4 of the Permit states that: "In accordance with Illinois Pollution Control Board
Order PCB 92-142, Temperature of the discharge to Clinton Lake from Clinton Power
Station, as measured at the second drop structure of the discharge flume shall be limited to
a daily average temperature which (1) does not exceed 99°F during more than 90 days in a
fixed calendar year running from January 1, through December 31, and (2) does not exceed
110.7 degrees Fahrenheit for any given day ."
Exelon requests a provisional variance from Special Condition 4 that allows Clinton Station's
discharge temperature to average above 99°F for a period of 30 additional days starting on
or about September 11, 2005, when the 90 days allowed by the plant's NPDES Permit are
reached .
Necessity For Request
Illinois has experienced extreme environmental conditions during summer 2005 including
heat and drought conditions. For the time period June 1 through August 31, the 74 .7°F
average temperature was 3.1 °F warmer than the long-term average and 6 .1 °F above the
same period a year ago . The Since March 2005, precipitation has been much below normal
over most of West Central and Northern Illinois, resulting in lower baseflows in streams and
rivers and below normal levels in reservoirs and lakes
.
Most of Northern and Western Illinois
remains in a severe or extreme drought . Statewide, March through August precipitation
is
the 6th driest on record. Even with normal precipitation for the remainder of August, this
would still result in the March through August precipitation in 2005 being the 7th lowest on
record. As of August 25th, March through August precipitation in Northwest, Northeast and
Central Illinois is the 3rd lowest on record. As a consequence of the unusually hot and humid
weather conditions and ongoing drought conditions, Clinton's discharge temperatures during
this summer have been much warmer than in previous years, resulting in increased use of
the Station's allotted 90 days during which its daily average discharge temperature may
exceed 99 degrees.
Historical data indicates that environmental conditions in September will continue to
result in
accumulation of days in which discharge temperatures will exceed an average of 99 °F .
These predicted conditions could change based on a combination of air temperature,
humidity and cloud cover
.
Clinton Lake's discharge temperature is a function of outside air temperature, intake
temperatures, and plant power levels. During periods when outside air temperature is
causing the daily average discharge temperature to exceed 99 °F, there is also high demand
Clinton Power Station

Page 3
on the electrical grid. As Clinton reduces power to control discharge temperature below
99°F, the Station's ability to support system voltage is diminished
.
Clinton is obligated to maintain a specific voltage level in order to ensure the reliability of the
electrical grid in this part of the state . This voltage level can be maintained so long as the
Station does not reduce real load below 1062 megawatts . However, under the current and
foreseeable weather and drought conditions, even when the Station maintains real load of
1062 megawatts, it may still cause daily average discharge temperatures to exceed
99 degrees
.
The requested provisional variance will enable Clinton Station to continue to maintain power
grid voltage in the service territory. Without the power that Clinton Station could generate as
a result of the requested provisional variance, there is increased risk that the energy needs
of Exelon's customers may not be met and depending on the operating status of other
generating stations in the area, Clinton Station continued operation may be essential for
voltage support for the Commonwealth Edison Company and Ameren IP Transmission
systems .
Assessment Of Environmental Impacts
The thermal impact of the requested provisional variance with respect to both the near-field
and far-field aquatic community is expected to be minimal . During September, which is
characterized by cooler nights and cooler daytime ambient air temperatures and lower
humidity, the cooling water discharged from the plant will evaporate to the atmosphere more
rapidly than during summer months
.
The 99°F limitation on average temperature at the end of the discharge canal was based on
a biological impact assessment that compared modeled lake temperatures to the habitats
where specific thermal tolerance limits would apply° for indicator fish species. The biological
impact assessment that was used to justify the 99 F temperature limit identified the most
restrictive temperature criteria to be the Short Term Maximum Temperature (STMT) for
embryo survival . High lake temperatures early in a year from a combination of earlier than
normal spring temperatures and heavy generation demands could restrict access to critical
spawning habitat or reduce the survivability of embryos and larval fish . Embryos and early
larval do not have the mobility to avoid areas above their thermal limits
. However the main
impact of warmer than normal lake temperatures in late summer or early fall is that juvenile
and adult fish will avoid portions of the lake above their thermal preferences for a longer
period. Although temperatures near the discharge would remain higher for 30 additional
days, thermal models indicate temperatures midway around the cooling lake loop will be
essentially back to ambient and provide adequate thermal refuges . Any reduced growth
rates resulting from the higher lake temperatures are usually more than offset by a longer
growing season in cooling lakes
.
Because Clinton Station is not proposing to increase cooling water flows or increase the
temperature of the cooling water discharge, resident fish species have already acclimated to
the existing discharge temperature. Resident fish species will not be subject to any heat
shock as a result of increasing the allotment of time for which the plant can discharge above
the 99°F average temperature .
Alternatives To Requested Relief
Clinton's lake discharge temperature is a function of both environmental conditions and plant
power level. As previously noted, the environmental conditions in 2005 have resulted in the
potential need for relief
.
Exelon evaluated several options prior to seeking regulatory relief to attempt to meet the
limit
from which the variance is requested . The most serious challenge faced was the
requirement to assure the reliability of the electrical grid
. Clinton supports the regional grid
operator (Ameren IP) by providing voltage support via reactive power . The reactive power
capability produced by the Station is directly proportional to the plant power level
. Higher
plant power levels provide more voltage support
.
Reduced grid voltage support can
challenge grid stability. Clinton is obligated to maintain a certain voltage level in
its
switchyard to ensure the reliability of the electrical grid in this part of the state
. This voltage
level can be maintained so long as the Station does not reduce real load below
1062 megawatts. Without Clinton's generation and voltage support, the transmission system
operator can only compensate for reduced grid voltage by starting fossil generating units in
the area. The need for Clinton's full reactive load support to the grid is most important
during periods of high demand (such as during day time periods with hot weather) . Given the
requirement to provide grid voltage support, Exelon has determined that a power reduction
to a constant lower value that would significantly reduce discharge temperature is not a
viable option. Without the power that Clinton Station could generate as a result of the
requested provisional variance, there is increased risk that the energy needs of Exelon's
customers may not be met, and depending on the operating status of other generating
stations in the area, Clinton Station continued operation may be essential for voltage support
for the Commonwealth Edison Company and Ameren IP Transmission systems
.
An alternative option evaluated was to reduce power output during the nighttime and then
increase power in time to provide the daily required voltage requirements
. This option
requires that the plant ramp down in the evening hours and remain at some reduced power
level until the early morning hours at a predetermined time that would ensure that the
resultant average discharge temperature was less than 99°F at the end of a 24-hour period .
To achieve the required plant power level changes on a nightly basis would challenge plant
systems and would not be in accordance with sound operating practices . Clinton is
designed to be base loaded at steady state conditions for long periods of time
.
Control
systems are tuned optimally for full power levels such that equipment performance
characteristics are most reliable . Frequent power changes present a challenge to integrity of
the nuclear fuel and thus, ultimately the environment
. Power changes are made by adjusting
the reactor core controls and thus present additional challenges to operations personnel
.
For both of these reasons, power adjustments are normally limited to only those required
.
Thus, the option of nightly power reductions was not determined to be viable
.
A third alternative evaluated the utilization of temporary mechanical draft cooling towers to
reduce the temperature of the cooling water discharged from the plant instead of being
discharged to the cooling lake. The cooling water discharged from the temporary towers
would then have to be re-routed back to the cooling lake which would require the installation
and operation of pumps, piping and sufficient temporary power to transport 649,100 gpm of
circulating water flow. The temporary cooling tower installation would be require a
considerable amount of space and would need to be installed adjacent to the discharge
canal to minimize the amount of piping runs and interconnecting piping. Whenever installing
Clinton Power Station

0-602361
Page
5
complex temporary systems there is always a concern with safety and reliability . There can
be unexpected power interruptions and/or equipment failures that have the potential of
complicating the ongoing operations of the temporary cooling towers . Renting temporary
pumps to pump water to the cooling towers would require the building of a temporary
structure to house them . The discharges from these pumps would have to be placed
adjacent to the discharge canal where a failure of a single temporary transfer pipe could be
catastrophic. For the short time period for which this provisional variance is required, there is
insufficient time to mobilize equipment and resources to accomplish this
.
Mitiqative Actions To Be Taken Durinq The Variance Period
During the period when the Station discharge exceeds the 99 °F average discharge
temperature authorized by the requested provisional variance, Clinton Power Station will do
the following: (1) reduce plant output to 1062 MWe; (2) continuously monitor the intake and
discharge temperatures and assess water temperatures specified in the NPDES Permit
; (3)
on a daily basis, inspect the intake and discharge areas to assess any mortalities to aquatic
life, and report the results of these monitoring activities to the Agency within 30 days of the
expiration of the provisional variance (or such other time as agreed upon by the Agency)
;
and (4) notify the Agency of any significant adverse environmental conditions observed that
might be caused by operations authorized by the provisional variance, including mortalities
to
fish or other aquatic life, investigate the cause of such conditions, provide the Agency
updates regarding the situation, including when normal conditions return, and submit a
report to the Agency regarding these matters within 30 days of the expiration of the
provisional variance period (or such other time as agreed upon by the Agency)
.
Summary
Exelon requests 30 additional days during which Clinton will be allowed to average above
99°F from the Station via outfall 002, the discharge flume pursuant to Special Condition 4
.
It
is Exelon's position that not granting this provisional variance to Clinton Station would
impose an arbitrary and unreasonable hardship for the foregoing reasons .
There is no other provisional variance relief in effect at this time for Clinton Station .
