NOTES

From: Robert AlejnikovSubject: Cooling Tower and Emergency Spray Pond

Date: 02/08/2008

Message:Particulate emission estimates for the cooling towers and emergency spray pond are based on calculationsemploying design circulating water rates, drift rates, evaporation rates, and actual total dissolved solidsmeasurements. Ammonia, CO, Lead, NOx, and SOx pollutants are not applicable for these water based sources.

From: Robert AlejnikovSubject: PM 2.5 for Cooling Towers and Spray Pond

Date: 02/08/2008

Message:Despit conducting thorough research, PM 2.5 emission factors were not able to be determined for the coolingtowers and the emergency spray pond.

Note: In order to continue to calculate the annual rolling Capacity Factor, it is necessary to update thespreadsheet at the beginning of each month. As each month passes for example; at the beginning of"February change the year ror column Jan '9 to Jan '00, update the MWh data and hours run for eachgenerator that tmonth.

Note: Sine fuel consumption of each emergency diesel engine is not metered.monthly fuel consumption is calculated by multiplying the prorated monthly MWhoutput for each diesel by the total fuel burn for all eight diesel engines.

Date: 02/04/2009

Message:Particulate emission estimates for the cooling towers and emergency spray pond are based on calculationsemploying design circulating water rates, drift rates, evaporation rates, and actual total dissolved solidsmeasurements. Ammonia, CO, Lead, NOx, and SOx pollutants are not applicable for these water based sources.

From: Robert AlejnikovSubject: PM2.5 for Cooling Towers and Spray Pond

Date: 02104(2009

Message:Despite conducting thorough research, PM2.5 emission factors were not able to be determined for the CoolingTowers and the Emergency Spray Pond.

From: Robert Alejnikov Date: 02/18/2009Subject: B.5.b pumpMessage:This submittal includes emission data for operation of the subject portable diesel driven pump. The actual emissiondata for the one hour run time is as follows:

Rolling Annual Capacity Factor and Rolling Fuel Consumption Calculation for Emergency Diesel Generation For The Month Ending 12/08

IFC. F. = ([- MWh (last 12 months)] / [(2.85 MW)(24 hr / day)(# of days in last 12 months)]* 100% 1uel Use for Each DIG for each month = [MWIh (each diesel) I MW\h (all diesels)]*[Total Fuel Burn - galsI

220 gal/hrin. '08 Feb. '08 Mar.'08

NA NA NA

n 'Feb. '08 Mar.'08

Note: In order to continue to calculate the annual rolling Capacity Factor, it is necessary to update thespreadsheet at the beginning of each month. As each month passes for example; at the beginning ofFebruary change the year for column Jan'99 to Jan'00, updatethe MWh data and hours run for eachgenerator that month.

Note: Since fuel consumption of each emergency diesel engine is not meteremonthly fuel consumption is calculated by multiplying the prorated monthlyoutput for each diesel by the total fuel bum for all eight diesel engines.

NOTES

From: Chris Conroy Date: 02/15/2010Subject: Contact Updates

Message:Under "INSP", please change S. Mitten to Leanne Birkmire

From: Chris Conroy Date: 02/15/2010Subject: Miscellaneous Emissions

Message:In accordance with Condition G #006 of the Title V Permit issued 12/07/2009, we are required to report emissionsfor the Insignificant Sources as per Condition G. The emission totals for these Insignificant Sources are shownunder this Miscellaneous Category that we added for this report. This also includes the VOC emissions fromSource ID 104 (Voltz Degreasing Unit). Mr. John Renalli of PA DEP agreed that this source should be reportedalong with the other Miscellaneous Sources because the emissions from it are less than one ton (they are only 0.2tons VOC).

From: Chris Conroy Date: 02/15/2010Subject: Cooling Tower and Emergency Spray PondMessage:PM10 emissions for the cooling towers and spray pond are based on recirc rates, drift rates, and total dissolvedsolids measurements. Despite conducting research, PM2.5 emission factors are not available. Other pollutants arenot applicable for these water-based sources.

From: Chris Conroy Date: 02/15/2010Subject: Boilers, Emergency Generators and Miscellaneous Emission FactorsMessage:The boiler emission factors for ammonia and POM are from FIRE/Title V application, and the methane emissionfactor is from EPA's Greenhouse Gas Protocol, 2004. The miscellaneous (insignificant sources) emission factorsare from theTitle V application.

From: Chris Conroy Date: 02/16/2010Subject: Boilers - Fuel BurnMessage:No Waste Derived Liquid Fuel (WDLF) was burned in 2009.

From: Chris Conroy Date: 02/16/2010Subject: SIC and NAICS Codes

Message:The first page of the report shows the SIC Code as 4911 - Trans. & Utilities - Electric Services. The 4911 Code iscorrect. Consider changing the description to: "Electric Services (nuclear electric power generation)".

The first page also shows the NAICS Code as 221112 - Fossil Fuel Electric Power Generation. While there arefossil fuel (oil-fired) emergency generators on site, Limerick Station is considered a nuclear power generatingfaciltiy. Consider changing the code and description to : 221113 - Nuclear Electric Power Geneation.

NOTES

From: Chris Conroy Date: 02/14/2011

Subject: Miscellaneous EmissionsMessage:In accordance with Condition G #006 of the Title V Permit issued 12/07/2009, we are required to report emissionsfor the Insignificant Sources as per Condition G. The emission totals for these Insignificant Sources are shownunder this Miscellaneous Category that we added for this report. This also includes the VOC emissions fromSource ID 104 (Voltz Degreasing Unit). Mr. John Renalli of PA DEP agreed that this source should be reportedalong with the other Miscellaneous Sources because the emissions from it are less than one ton.

From: Chris Conroy Date: 02/14/2011Subject: Cooling Tower and Emergency Spray PondMessage:NEED TO EXPLAIN BIG INCREASE IN REPORTED EMISSIONSPM 10 emissions for the cooling towers and spray pond are based on recirc rates, drift rates, and total dissolvedsolids measurements.

Despite conducting research, PM2.5 emission factors are not available. Other pollutants are not applicable forthese water-based sources.


Subject: Boilers, Emergency Generators and Miscellaneous Emission FactorsMessage:The boiler emission factors for ammonia and POM are from FIRE/Title V application, and the methane emissionfactor is from EPA's Greenhouse Gas Protocol, 2004. The miscellaneous (insignificant sources) emission factorsare from theTitle V application.


Subject: Boilers - Fuel BurnMessage:No Waste Derived Liquid Fuel (WDLF) was burned in 2010.

NOTES

From: Chris Conroy Date: 02/15/2011Subject: Cooling Tower EmissionsMessage:The reported PM10 emissions from each Cooling Tower are greater than the emissions reported for these units inpast years. The increase is due to a change in emission calculation methodology as explained further below. Therehas been no change in the cooling tower operation and no change in actual PM10 emissions.

Cooling tower PM10 emissions are calculated using a mass balance formula: circulating water flow rate in thetower x total dissolved solids concentration in the water x percent drift rate from the tower. Prior to 2010, thiscalculation was performed using fixed values for these parameters that were included in the Title V permitapplication for the facility. With the reissuance of a new Title V permit in December 2009, the calculationmethodology was revised as follows:

1) actual circulating water flowrates were used instead of a fixed design flow rate. Actual 2010 rates were slightlyless than the previously-used design rates.2) Actual 2010 total dissolved solids (TDS) values based on weekly sampling were used instead of a fixedhistorical value. The measured TDS in 2010 (yearly average was 1330 mg/I) was greater than the historical TDSvalue used in past years calculations (599 mg/I).3) A drift rate of 0.0065% was used beginning in 2010, instead of a 0.003% drift rate which was used in past yearsreporting. Exelon retained A114, Inc. consultants to evaluate drift rate factors for the cooling towers. Based on athorough review of available data by A114 Inc., this new drift rate was considered to be a more conservativeestimate of drift (no site-specific drift rate data is available). Both the previous drift rate and the new drift ratechosen by Exelon for its cooling towers is significantly more conservative than that used by U.S. EPA as presentedAP-42 (0.00088%, with an emission factor quality rating of E).

The above change combined to result in an increase in calculated PM10 emissions compared to that using the oldmethodology. As discussed above, there has been no change in the cooling tower operation and no change inactual PM10 emissions. The increase is due only to using a more conservative calculation methodology in 2010.
