Subject Dispersion Modeling for Dominion Energy s 9 Januar 2009 REVISED PSD Permit Application for a Major Modification ofthe Brayton Point Generating Station
122 2ajFrom ey Region 1 Modeling Contact Air Permits Program
To Brendan McCahil
This details my comments on the adequacy and regulatory implications of dispersion modeling prepared for a major modification of the Brayton Point Generating Station (Somerset Massachusetts) The modeling appears in the document entitled REVISED 310 CMR 7 Major Comprehensive Plan Approval and Prevention of Significant Deterioration Application for the Closed Cycle Cooling and Unit 3 Dry ScrubberFabric Filter Projects at Dominion Energy Brayton Point LLC prepared by Epsilon Associates for Dominion Energy Brayton Point LLC whose Vice President Pamela F Faggert submitted it to Region 1 US EP A on 9 January 2009
In the document submitted to Region 1 Dominion quantifies significant (over 15 tpy) PMlO emission increases from the construction and operation of two natural draft cooling towers at the power plant together with installation of a dry scrubberfabric filter (DSFF) for S02 emission control on Unit 3 No other emission changes were calculated so it only can be concluded fTOm the January document that dispersion modeling ofPMI0 and PM25 ( significant if over 10 tpy filterable) would be required for PSD permitting
All emissions in tpy Base Actual Potential Increase
2 new natural draft cooling towers
Total PMI0 389 389
Filterable PM2 389 389
DSFF retrofit on Unit 3
Total PMI0 670 464 206
Filterable PM2 134 186
Net Proposed Increases
Total PMI0 183
441Filterable PM2
Note that Dominion has likely overestimated PM emission increases from the cooling towers because after a discussion with EPA s John Bosch Region 1 was unable to accept Dominion initial proposal which would discount drift PM with a physical diameter greater than 011
Therefore Dominion instead estimated PM emissions using AP-42 which is generally considered to provide a ceiling on actual emissions from cooling towers
EP A regulations require dispersion modeling of over significant PM2 5 and PMl 0 increases in PSD permitting as follows
40- CFR 5221 (b)(15)(i) defines the pollutant-specific baseline area to include the section 107 area where a major new source or modification would build or any intrastate section 107 area where it would have an annual impact greater than llgm ofthe pollutant
Dominion s submittal does not identif any area where minor baseline area would be set because the permitted modifcations would have annual P M10 impacts greater than 1 flgm However in the permit application Dominion requests a finding from EP A on the matter
Stephen Dennis of Massachusetts DEP e-mailed a spreadsheet PSD permits and PSD SIP Revisions in Massachusetts Consuming PSD Increment as of 1112008 to Region 1 on 11- 2008 with a request to update for sources permitted after DEP returned the PSD program to EP A The spreadsheet lists no PSD subject major source activity within the Town of Somerset section 107 area to set the minor source baseline for any pollutant
In an e-mail of 1-20-2009 Stephen Dennis indicates the closest towns to Somerset where minor source PM baseline area was set are New Bedford (on 11-1994 by the New Bedford Cogeneration Facility spermit application) and Rochester (on 8- 1980 by
permit application) Because the New Bedford cogenerator was never built and since SEMASS was modeled with under ugm3 annual impacts neither has set PM baseline on Somerset or any other nearby section 107 area From this it can be concluded that minor source baseline has not been set in Somerset that all emissions interacting with Brayton Point s are baselined consume no increment -and that the applicationfor the DSFF and cooling tower PSD permit wil initiate the Somerset PM10 baseline area
SEMASS RR
Although Massachusetts uses towns for section 107 areas for PMJO 40 CFR 81 322 designates all of Bristol County attainment or unclassifable for P M2 5 making the county not the town the section 107 unit to use for P M2 5 Therefore Dominion s PSD permit application wil make all of Bristol County a baseline areafor PM2
40 CFR 5221 (k) Source impact analysis requires dispersion modeling to show that over significant emission increases from the modification
Wil not contribute to a violation of ambient air quality standards (See 40 CFR 50 (PMI0J and 50 13 (PM2 5J) and
Will not contribute to maximum allowable increase over the baseline concentration (See 40 CFR 5221 ( c)) For brevity these allowable increases are often called increment
See the paragraphs following the ending table
40 CFR 5221(1) Air quality models requires that the dispersion models in 40 CFR 51 Appendix W be used to estimate all ambient pollutant concentrations
Dominion modeled Brayton Point s stacks and natural draft cooling tower using EP guideline (Appendix W)AERMOD dispersion model guideline preprocessors and 5
years (2002 and2004- 7 TF Green surface meteorological data with contemporary upper air data from Morris Island in Chatham) While use of a continuous record of 5
years of meterorological data is preferred TF Green s data capture for 2003 was substandard
40 CFR 5221(m) Air quality analysis requires an analysis of at least one year of generally continuous air quality data representative of the area that over significant emission increaseswould affect
Thefollowingfigure identifes locations of monitoring sites collecting PM2 5 and PM10 data representative of the areas Brayton Point s PM emission increases would affect Dominion selected data from these sites and combined it with modeling data to assess whether the plant modifcation would comply with PM2 5 and PM10 standards

40 CFR 5221(0) Additional impacts analysis requires an assessment of the impacts on visibility soils and vegetation of emissions from the modification and associated growth
did not require Dominion to assess the visual impact of the cooling towers steam plumes because water vapor and water dropletsaerosols are not pollutants regulated by the Clean Air Act Dominion modeled salt deposition from cooling tower
Region
drif using the nonguideline SA CTI (Seasonal-Annual Cooling Tower Impact) Model
Appendix W is mandatory for concentration calculations not deposition estimates
40 CFR 5221(0) Sources impacting Federal Class I areas requires EPA to give wrtten notice
to the Federal Land Manager of any Class 1 area which the increase in emissions from a major new of modified source may affect
Dominion assessed the impact of the increase in PM emissions at Brayton Point on visibility in the nearest Class I area (Lye Brook Wilderness Vermont) with the
VISCREEN Model The models Levell screen showed no potentialfor visibilty km awayimpairment in the Class 1 area 213
40 CFR 5221(k) Source impact analysis Discussion continued

PM25 annual air quality standard is-met when the average of the arithmetic annual average over three consecutive years falls below 15 flgmNotes
The PM2 5 24-hour will be met when the 98-tile highest monitored PM2 flgmconcentration averaged over three consecutive years is under 35
The PMI0 24-hour standard is met when the expected number of exceedances of 150 flgm is less than or equalto one
Brayton Point s modeled PM25 and PMI0 impacts above represent maximum anual and 24shy
l)our impacts from the entire plant not merely the increases from the two new cooling towers and DSFF control system on Unit 3 Consequently the next three paragraphs which could have considered PM emission increases alone make highly conservative comparisons against action
levels
SILs or significant impact levels Emissionincreases from new and modified facilities can be permitted in designated attainment areas in the presence of air quality standards violations
40 CFR Parprovided the increase in ambient impacts from the facility fall below these levels
51 Appendix S II tabulates the significance levels Because Brayton Points 24- hour PMI0 impact 219 Jgm
3 exceeds the 5Jgm3 PMI0SIL compliance with increments and air quality standards must be more directly addressed
Monitoring exclusion Because Brayton Points 24- hour 219 Jgm3 PMI0 impact exceeds the 10Jgm3 PMI0 exclusion level the preconstruction monitoring exemption at 40 CFR 5221(i)(5)
does not appear a possibility In any event several recent years ofPMI0 and PM2 representative of the area were available and used in the air qualityanalysis required in 40 CFR
5221(m) as described above Dominion sought no preconstruction monitoring exemption
Increment An increment is the maximum amount by which existing ambient air pollutant concentrations can be allowed to increase thereby approaching an air quality standard 40 CFR 51 166( c) lists the Class IT ambient air increments that apply in Somerset Massachusetts
Because Brayton Points 24- hour 219 Jgm3 PMI0 impact falls below the 30Jgm3 PMI0 3 the increase in PMI0 emission wilincrement and its 17 Jgm anual impact below 17 Jgm
not exceed Class IT increments Note again that most of the emissions Dominion modeled would not result from the modification and do not consume increment
NAAOS The National Ambient Air Quality Standards represent the air pollutant concentrations or levels below which there wil be no adverse effects on health or welfare Compliance with the PM NAAQS is shown by comparing the last line ofthe table which sums
Brayton Points modeled impacts with background PM measurements against the NAAQS appearing in the same column In all cases Total PM concentration falls below the level of and
comply with theNAAQS
The bottom half of the table presents extracts from Dominion s modeling ofPM25 and PMI0 emissions from Brayton Point Note the following all important
Limiting or highest whole source impacts occur at intermediate 10ads (and PM emission rates) - Unit s 1 and 4 operating at 14082250 14082250 35005655 and
24394800 all in units ofmodeled heat input to maximum heat input
Initially modeling compliance against the PM25 and PMl 0 24-hour NAAQS seemed problematic In 2002 Somerset Generating Station (northwest of Brayton Point in the figure above) emitted 199 tpy PM25 and 229 tpy PMI0 Brayton Point s PM impacts approach the two standards and because the increase in Brayton Point s PM emissions
3 SIL(from Unit 3 especially) may cause PM concentration increases over the 5 Jgm(Significant hnpact Level) Dominion should have performed interactive or cumulative PM modeling to include Somerset Generating Station On 14 January AJ Jablonowski
of Epsilon (Dominion s engineering-consultant) e-mailed Region 1 more curent data for Somers t Station showing monotonically decreasing PM emission decreases from 70 tpy PMI0 and 31 tpy PM25 in 2005 to 50 tpy and 23 tpy respectively in 2007 The omission of Somerset from the modeling is in accord with the modeling protocol and acceptable
In an e-mail on 1- 15-2009 Stephen Dennis noted that in permit modellng Massachusetts DEP often requires interactive or cumulative modeling of sources with actual emissions over 100 tpy and within 1 0 km of the permit applicant SomersetStation s PM emissions are lower Note too that Dominion s modeling of Brayton Point has conservatively modeled highest 8 high and highest 2 high model PM2 5 and PMl 0 emissions against the respective PM 24-hour NAAQS where average highest 8 high and highest
high model estimates could have been used The NAAQS analyses also very conservatively assume that monitors record highest PM under conditions corresponding to highest modelled PM impacts

Subject RE Brayton Point
Brian I think we are in agreement
1 The Taunton Energy PSD application did not trigger minor sourcebaseline
for PM10 because a PSD review for PM10 was not required
2 The New Bedford Cogen PSD applications triggered minor sourcebaseline for
PM10 in New Bedford The New Bedford Cogen application didn trigger minor
source baseline anywhere else because its 1 ugm3 PMI0 annual isopleth did
not extend outside New Bedford
3 The SEMASS PSD applications triggered minor source baseline for PMI0
Rochester SEMASS PMI0 impacts are below all PMI0 SILs
4 PMI0 minor source baseline has not yet been triggered in Somerset Dominion
will trigger PMI0 minor source baseline in Somerset and any other municipalities located within its 1 ugm3 annual average PMI0
isopleth
5 Dominion will consume PMI0 increment in Somerset if Dominion PMI0 impacts
are above PMI0 SILs in Somerset Dominion will also consume PMI0 increment
in other municipalities where PM10 baseline has been triggered (such as New
Bedford) if Dominion PMI0 impacts are above PMI0 SILs in suchmunicipalities
By the way neither Taunton Energy nor New Bedford Cogen were built and therefore would not consume PSD increment Any ideas on how to untrigger PMI0 minor source baseline in Taunton and New Bedford assuming it s possible

Steve shy
We go by the date a complete PSD permit application was filed the source need not actually build although where the source does not build
some states have been able to untrigger baseline My review of the Brayton Point case only looked at the Taunton Energy Center- reportedly closest to Somerset - but the plant hardly matters because your 11-1-2008 spreadsheet indicates it is below significant for PM a bit concerned however about the SEMASS (Rochester) and the New Bedford cogen because while they be a bit more distant both wereemissions-significant for PM With impacts below the SILs SEMASS could not set PM baseline area anywhere but in Rochester That leaves the New Bedford cogen as a possible trigger for Somerset PM baseline My review of Dominion s permit modeling concluded that the Somerset baseline area had not been set yet for PM and therefore that only PMemission increases linked to the DSFF control and 2 cooling towers needed to bemodeled for increment consumption wi thin Somerset
The cog en s not more a concern as a trigger for prior incrementconsumption by sources wi thin Somerset than as an increment consumeritself And thanks for your words on selecting nearby sources for interactivemodeling

RE Brayton Point Subj ect
The closest existing PSD source in Massachusetts is SEMASS in Rochester about 10 miles distant Its impacts are below SILs so it would not have to be included in a PSD increment consumption analysis (do youagree Brian)
In the early 90 s there was a PSD application in New Bedford and a PSD application in Taunton - but they were never constructed and therefore wouldn t consume PSD increments (do you agree Brian)
A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

Steve When we talked about the PSD status of the area for Brayton Point you thought that there may have been permits submitted triggering PSD baseline but that these projects have never been built You said you would check with Brian Hennessey at EPA about any other cumulative sources and PSD increment consuming sources in the area of Brayton Pt Have you had a chance to do that We are trying to wrap this up and have assumed so far that there are no interactive sources but confirmation would be helpful Than ks Liz

Subject Somerset Station
Brian
At the request of Scott Lawton of Dominion I am forwarding to you the attached spreadsheet which is a summary of Massachusetts DEP source inventory data for emissions for calendar year 2005 Somerset Station is on row 656 and shows actual emissions of 697083 tons PM10 and 307701 tons PM2
Based on Scott s recollection a reduction in emissions between 2002 and 2005 would be consistent with operational changes that took place at Somerset Station
I found the data you discussed yesterday on the EPA AIRS database I noted that the EPA AIRS
database defines Pollutant Emissions as follows
An emissions estimate is based on the normal operating schedule of a source and includes the effects of installed pollution control equipment and regulatory restrictions on operating conditions This is called estimated emissions with rule effectiveness
Based on that description the data in the EPA AIRS database could be potential emissions rather than actual emissions
The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling

Note that Dominion has likely overestimated PM emission increases from the cooling towers because after a discussion with EPA s John Bosch Region 1 was unable to accept Dominion initial proposal which would discount drift PM with a physical diameter greater than 011
Therefore Dominion instead estimated PM emissions using AP-42 which is generally considered to provide a ceiling on actual emissions from cooling towers
EP A regulations require dispersion modeling of over significant PM2 5 and PMl 0 increases in PSD permitting as follows
40- CFR 5221 (b)(15)(i) defines the pollutant-specific baseline area to include the section 107 area where a major new source or modification would build or any intrastate section 107 area where it would have an annual impact greater than llgm ofthe pollutant
Dominion s submittal does not identif any area where minor baseline area would be set because the permitted modifcations would have annual P M10 impacts greater than 1 flgm However in the permit application Dominion requests a finding from EP A on the matter
Stephen Dennis of Massachusetts DEP e-mailed a spreadsheet PSD permits and PSD SIP Revisions in Massachusetts Consuming PSD Increment as of 1112008 to Region 1 on 11- 2008 with a request to update for sources permitted after DEP returned the PSD program to EP A The spreadsheet lists no PSD subject major source activity within the Town of Somerset section 107 area to set the minor source baseline for any pollutant
In an e-mail of 1-20-2009 Stephen Dennis indicates the closest towns to Somerset where minor source PM baseline area was set are New Bedford (on 11-1994 by the New Bedford Cogeneration Facility spermit application) and Rochester (on 8- 1980 by
permit application) Because the New Bedford cogenerator was never built and since SEMASS was modeled with under ugm3 annual impacts neither has set PM baseline on Somerset or any other nearby section 107 area From this it can be concluded that minor source baseline has not been set in Somerset that all emissions interacting with Brayton Point s are baselined consume no increment -and that the applicationfor the DSFF and cooling tower PSD permit wil initiate the Somerset PM10 baseline area
SEMASS RR
Although Massachusetts uses towns for section 107 areas for PMJO 40 CFR 81 322 designates all of Bristol County attainment or unclassifable for P M2 5 making the county not the town the section 107 unit to use for P M2 5 Therefore Dominion s PSD permit application wil make all of Bristol County a baseline areafor PM2
40 CFR 5221 (k) Source impact analysis requires dispersion modeling to show that over significant emission increases from the modification
Wil not contribute to a violation of ambient air quality standards (See 40 CFR 50 (PMI0J and 50 13 (PM2 5J) and
Will not contribute to maximum allowable increase over the baseline concentration (See 40 CFR 5221 ( c)) For brevity these allowable increases are often called increment
See the paragraphs following the ending table
40 CFR 5221(1) Air quality models requires that the dispersion models in 40 CFR 51 Appendix W be used to estimate all ambient pollutant concentrations
Dominion modeled Brayton Point s stacks and natural draft cooling tower using EP guideline (Appendix W)AERMOD dispersion model guideline preprocessors and 5
years (2002 and2004- 7 TF Green surface meteorological data with contemporary upper air data from Morris Island in Chatham) While use of a continuous record of 5
years of meterorological data is preferred TF Green s data capture for 2003 was substandard
40 CFR 5221(m) Air quality analysis requires an analysis of at least one year of generally continuous air quality data representative of the area that over significant emission increaseswould affect
Thefollowingfigure identifes locations of monitoring sites collecting PM2 5 and PM10 data representative of the areas Brayton Point s PM emission increases would affect Dominion selected data from these sites and combined it with modeling data to assess whether the plant modifcation would comply with PM2 5 and PM10 standards

40 CFR 5221(0) Additional impacts analysis requires an assessment of the impacts on visibility soils and vegetation of emissions from the modification and associated growth
did not require Dominion to assess the visual impact of the cooling towers steam plumes because water vapor and water dropletsaerosols are not pollutants regulated by the Clean Air Act Dominion modeled salt deposition from cooling tower
Region
drif using the nonguideline SA CTI (Seasonal-Annual Cooling Tower Impact) Model
Appendix W is mandatory for concentration calculations not deposition estimates
40 CFR 5221(0) Sources impacting Federal Class I areas requires EPA to give wrtten notice
to the Federal Land Manager of any Class 1 area which the increase in emissions from a major new of modified source may affect
Dominion assessed the impact of the increase in PM emissions at Brayton Point on visibility in the nearest Class I area (Lye Brook Wilderness Vermont) with the
VISCREEN Model The models Levell screen showed no potentialfor visibilty km awayimpairment in the Class 1 area 213

PM25 annual air quality standard is-met when the average of the arithmetic annual average over three consecutive years falls below 15 flgmNotes
The PM2 5 24-hour will be met when the 98-tile highest monitored PM2 flgmconcentration averaged over three consecutive years is under 35
The PMI0 24-hour standard is met when the expected number of exceedances of 150 flgm is less than or equalto one
Brayton Point s modeled PM25 and PMI0 impacts above represent maximum anual and 24shy
l)our impacts from the entire plant not merely the increases from the two new cooling towers and DSFF control system on Unit 3 Consequently the next three paragraphs which could have considered PM emission increases alone make highly conservative comparisons against action
levels
SILs or significant impact levels Emissionincreases from new and modified facilities can be permitted in designated attainment areas in the presence of air quality standards violations
40 CFR Parprovided the increase in ambient impacts from the facility fall below these levels
51 Appendix S II tabulates the significance levels Because Brayton Points 24- hour PMI0 impact 219 Jgm
3 exceeds the 5Jgm3 PMI0SIL compliance with increments and air quality standards must be more directly addressed
Monitoring exclusion Because Brayton Points 24- hour 219 Jgm3 PMI0 impact exceeds the 10Jgm3 PMI0 exclusion level the preconstruction monitoring exemption at 40 CFR 5221(i)(5)
does not appear a possibility In any event several recent years ofPMI0 and PM2 representative of the area were available and used in the air qualityanalysis required in 40 CFR
5221(m) as described above Dominion sought no preconstruction monitoring exemption
Increment An increment is the maximum amount by which existing ambient air pollutant concentrations can be allowed to increase thereby approaching an air quality standard 40 CFR 51 166( c) lists the Class IT ambient air increments that apply in Somerset Massachusetts
Because Brayton Points 24- hour 219 Jgm3 PMI0 impact falls below the 30Jgm3 PMI0 3 the increase in PMI0 emission wilincrement and its 17 Jgm anual impact below 17 Jgm
not exceed Class IT increments Note again that most of the emissions Dominion modeled would not result from the modification and do not consume increment
NAAOS The National Ambient Air Quality Standards represent the air pollutant concentrations or levels below which there wil be no adverse effects on health or welfare Compliance with the PM NAAQS is shown by comparing the last line ofthe table which sums
Brayton Points modeled impacts with background PM measurements against the NAAQS appearing in the same column In all cases Total PM concentration falls below the level of and
comply with theNAAQS
The bottom half of the table presents extracts from Dominion s modeling ofPM25 and PMI0 emissions from Brayton Point Note the following all important
Limiting or highest whole source impacts occur at intermediate 10ads (and PM emission rates) - Unit s 1 and 4 operating at 14082250 14082250 35005655 and
24394800 all in units ofmodeled heat input to maximum heat input
Initially modeling compliance against the PM25 and PMl 0 24-hour NAAQS seemed problematic In 2002 Somerset Generating Station (northwest of Brayton Point in the figure above) emitted 199 tpy PM25 and 229 tpy PMI0 Brayton Point s PM impacts approach the two standards and because the increase in Brayton Point s PM emissions
3 SIL(from Unit 3 especially) may cause PM concentration increases over the 5 Jgm(Significant hnpact Level) Dominion should have performed interactive or cumulative PM modeling to include Somerset Generating Station On 14 January AJ Jablonowski
of Epsilon (Dominion s engineering-consultant) e-mailed Region 1 more curent data for Somers t Station showing monotonically decreasing PM emission decreases from 70 tpy PMI0 and 31 tpy PM25 in 2005 to 50 tpy and 23 tpy respectively in 2007 The omission of Somerset from the modeling is in accord with the modeling protocol and acceptable
In an e-mail on 1- 15-2009 Stephen Dennis noted that in permit modellng Massachusetts DEP often requires interactive or cumulative modeling of sources with actual emissions over 100 tpy and within 1 0 km of the permit applicant SomersetStation s PM emissions are lower Note too that Dominion s modeling of Brayton Point has conservatively modeled highest 8 high and highest 2 high model PM2 5 and PMl 0 emissions against the respective PM 24-hour NAAQS where average highest 8 high and highest
high model estimates could have been used The NAAQS analyses also very conservatively assume that monitors record highest PM under conditions corresponding to highest modelled PM impacts

Subject RE Brayton Point
Brian I think we are in agreement
1 The Taunton Energy PSD application did not trigger minor sourcebaseline
for PM10 because a PSD review for PM10 was not required
2 The New Bedford Cogen PSD applications triggered minor sourcebaseline for
PM10 in New Bedford The New Bedford Cogen application didn trigger minor
source baseline anywhere else because its 1 ugm3 PMI0 annual isopleth did
not extend outside New Bedford
3 The SEMASS PSD applications triggered minor source baseline for PMI0
Rochester SEMASS PMI0 impacts are below all PMI0 SILs
4 PMI0 minor source baseline has not yet been triggered in Somerset Dominion
will trigger PMI0 minor source baseline in Somerset and any other municipalities located within its 1 ugm3 annual average PMI0
isopleth
5 Dominion will consume PMI0 increment in Somerset if Dominion PMI0 impacts
are above PMI0 SILs in Somerset Dominion will also consume PMI0 increment
in other municipalities where PM10 baseline has been triggered (such as New
Bedford) if Dominion PMI0 impacts are above PMI0 SILs in suchmunicipalities
By the way neither Taunton Energy nor New Bedford Cogen were built and therefore would not consume PSD increment Any ideas on how to untrigger PMI0 minor source baseline in Taunton and New Bedford assuming it s possible

Steve shy
We go by the date a complete PSD permit application was filed the source need not actually build although where the source does not build
some states have been able to untrigger baseline My review of the Brayton Point case only looked at the Taunton Energy Center- reportedly closest to Somerset - but the plant hardly matters because your 11-1-2008 spreadsheet indicates it is below significant for PM a bit concerned however about the SEMASS (Rochester) and the New Bedford cogen because while they be a bit more distant both wereemissions-significant for PM With impacts below the SILs SEMASS could not set PM baseline area anywhere but in Rochester That leaves the New Bedford cogen as a possible trigger for Somerset PM baseline My review of Dominion s permit modeling concluded that the Somerset baseline area had not been set yet for PM and therefore that only PMemission increases linked to the DSFF control and 2 cooling towers needed to bemodeled for increment consumption wi thin Somerset
The cog en s not more a concern as a trigger for prior incrementconsumption by sources wi thin Somerset than as an increment consumeritself And thanks for your words on selecting nearby sources for interactivemodeling

RE Brayton Point Subj ect
The closest existing PSD source in Massachusetts is SEMASS in Rochester about 10 miles distant Its impacts are below SILs so it would not have to be included in a PSD increment consumption analysis (do youagree Brian)
In the early 90 s there was a PSD application in New Bedford and a PSD application in Taunton - but they were never constructed and therefore wouldn t consume PSD increments (do you agree Brian)
A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

Steve When we talked about the PSD status of the area for Brayton Point you thought that there may have been permits submitted triggering PSD baseline but that these projects have never been built You said you would check with Brian Hennessey at EPA about any other cumulative sources and PSD increment consuming sources in the area of Brayton Pt Have you had a chance to do that We are trying to wrap this up and have assumed so far that there are no interactive sources but confirmation would be helpful Than ks Liz

Subject Somerset Station
Brian
At the request of Scott Lawton of Dominion I am forwarding to you the attached spreadsheet which is a summary of Massachusetts DEP source inventory data for emissions for calendar year 2005 Somerset Station is on row 656 and shows actual emissions of 697083 tons PM10 and 307701 tons PM2
Based on Scott s recollection a reduction in emissions between 2002 and 2005 would be consistent with operational changes that took place at Somerset Station
I found the data you discussed yesterday on the EPA AIRS database I noted that the EPA AIRS
database defines Pollutant Emissions as follows
An emissions estimate is based on the normal operating schedule of a source and includes the effects of installed pollution control equipment and regulatory restrictions on operating conditions This is called estimated emissions with rule effectiveness
Based on that description the data in the EPA AIRS database could be potential emissions rather than actual emissions
The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling

See the paragraphs following the ending table
40 CFR 5221(1) Air quality models requires that the dispersion models in 40 CFR 51 Appendix W be used to estimate all ambient pollutant concentrations
Dominion modeled Brayton Point s stacks and natural draft cooling tower using EP guideline (Appendix W)AERMOD dispersion model guideline preprocessors and 5
years (2002 and2004- 7 TF Green surface meteorological data with contemporary upper air data from Morris Island in Chatham) While use of a continuous record of 5
years of meterorological data is preferred TF Green s data capture for 2003 was substandard
40 CFR 5221(m) Air quality analysis requires an analysis of at least one year of generally continuous air quality data representative of the area that over significant emission increaseswould affect
Thefollowingfigure identifes locations of monitoring sites collecting PM2 5 and PM10 data representative of the areas Brayton Point s PM emission increases would affect Dominion selected data from these sites and combined it with modeling data to assess whether the plant modifcation would comply with PM2 5 and PM10 standards

---------------------------------------------------------------------------------------------------------
40 CFR 5221(0) Additional impacts analysis requires an assessment of the impacts on visibility soils and vegetation of emissions from the modification and associated growth
did not require Dominion to assess the visual impact of the cooling towers steam plumes because water vapor and water dropletsaerosols are not pollutants regulated by the Clean Air Act Dominion modeled salt deposition from cooling tower
Region
drif using the nonguideline SA CTI (Seasonal-Annual Cooling Tower Impact) Model
Appendix W is mandatory for concentration calculations not deposition estimates
40 CFR 5221(0) Sources impacting Federal Class I areas requires EPA to give wrtten notice
to the Federal Land Manager of any Class 1 area which the increase in emissions from a major new of modified source may affect
Dominion assessed the impact of the increase in PM emissions at Brayton Point on visibility in the nearest Class I area (Lye Brook Wilderness Vermont) with the
VISCREEN Model The models Levell screen showed no potentialfor visibilty km awayimpairment in the Class 1 area 213
40 CFR 5221(k) Source impact analysis Discussion continued

PM25 annual air quality standard is-met when the average of the arithmetic annual average over three consecutive years falls below 15 flgmNotes
The PM2 5 24-hour will be met when the 98-tile highest monitored PM2 flgmconcentration averaged over three consecutive years is under 35
The PMI0 24-hour standard is met when the expected number of exceedances of 150 flgm is less than or equalto one
Brayton Point s modeled PM25 and PMI0 impacts above represent maximum anual and 24shy
l)our impacts from the entire plant not merely the increases from the two new cooling towers and DSFF control system on Unit 3 Consequently the next three paragraphs which could have considered PM emission increases alone make highly conservative comparisons against action
levels
SILs or significant impact levels Emissionincreases from new and modified facilities can be permitted in designated attainment areas in the presence of air quality standards violations
40 CFR Parprovided the increase in ambient impacts from the facility fall below these levels
51 Appendix S II tabulates the significance levels Because Brayton Points 24- hour PMI0 impact 219 Jgm
3 exceeds the 5Jgm3 PMI0SIL compliance with increments and air quality standards must be more directly addressed
Monitoring exclusion Because Brayton Points 24- hour 219 Jgm3 PMI0 impact exceeds the 10Jgm3 PMI0 exclusion level the preconstruction monitoring exemption at 40 CFR 5221(i)(5)
does not appear a possibility In any event several recent years ofPMI0 and PM2 representative of the area were available and used in the air qualityanalysis required in 40 CFR
5221(m) as described above Dominion sought no preconstruction monitoring exemption
Increment An increment is the maximum amount by which existing ambient air pollutant concentrations can be allowed to increase thereby approaching an air quality standard 40 CFR 51 166( c) lists the Class IT ambient air increments that apply in Somerset Massachusetts
Because Brayton Points 24- hour 219 Jgm3 PMI0 impact falls below the 30Jgm3 PMI0 3 the increase in PMI0 emission wilincrement and its 17 Jgm anual impact below 17 Jgm
not exceed Class IT increments Note again that most of the emissions Dominion modeled would not result from the modification and do not consume increment
NAAOS The National Ambient Air Quality Standards represent the air pollutant concentrations or levels below which there wil be no adverse effects on health or welfare Compliance with the PM NAAQS is shown by comparing the last line ofthe table which sums
Brayton Points modeled impacts with background PM measurements against the NAAQS appearing in the same column In all cases Total PM concentration falls below the level of and
comply with theNAAQS
The bottom half of the table presents extracts from Dominion s modeling ofPM25 and PMI0 emissions from Brayton Point Note the following all important
Limiting or highest whole source impacts occur at intermediate 10ads (and PM emission rates) - Unit s 1 and 4 operating at 14082250 14082250 35005655 and
24394800 all in units ofmodeled heat input to maximum heat input
Initially modeling compliance against the PM25 and PMl 0 24-hour NAAQS seemed problematic In 2002 Somerset Generating Station (northwest of Brayton Point in the figure above) emitted 199 tpy PM25 and 229 tpy PMI0 Brayton Point s PM impacts approach the two standards and because the increase in Brayton Point s PM emissions
3 SIL(from Unit 3 especially) may cause PM concentration increases over the 5 Jgm(Significant hnpact Level) Dominion should have performed interactive or cumulative PM modeling to include Somerset Generating Station On 14 January AJ Jablonowski
of Epsilon (Dominion s engineering-consultant) e-mailed Region 1 more curent data for Somers t Station showing monotonically decreasing PM emission decreases from 70 tpy PMI0 and 31 tpy PM25 in 2005 to 50 tpy and 23 tpy respectively in 2007 The omission of Somerset from the modeling is in accord with the modeling protocol and acceptable
In an e-mail on 1- 15-2009 Stephen Dennis noted that in permit modellng Massachusetts DEP often requires interactive or cumulative modeling of sources with actual emissions over 100 tpy and within 1 0 km of the permit applicant SomersetStation s PM emissions are lower Note too that Dominion s modeling of Brayton Point has conservatively modeled highest 8 high and highest 2 high model PM2 5 and PMl 0 emissions against the respective PM 24-hour NAAQS where average highest 8 high and highest
high model estimates could have been used The NAAQS analyses also very conservatively assume that monitors record highest PM under conditions corresponding to highest modelled PM impacts

Subject RE Brayton Point
Brian I think we are in agreement
1 The Taunton Energy PSD application did not trigger minor sourcebaseline
for PM10 because a PSD review for PM10 was not required
2 The New Bedford Cogen PSD applications triggered minor sourcebaseline for
PM10 in New Bedford The New Bedford Cogen application didn trigger minor
source baseline anywhere else because its 1 ugm3 PMI0 annual isopleth did
not extend outside New Bedford
3 The SEMASS PSD applications triggered minor source baseline for PMI0
Rochester SEMASS PMI0 impacts are below all PMI0 SILs
4 PMI0 minor source baseline has not yet been triggered in Somerset Dominion
will trigger PMI0 minor source baseline in Somerset and any other municipalities located within its 1 ugm3 annual average PMI0
isopleth
5 Dominion will consume PMI0 increment in Somerset if Dominion PMI0 impacts
are above PMI0 SILs in Somerset Dominion will also consume PMI0 increment
in other municipalities where PM10 baseline has been triggered (such as New
Bedford) if Dominion PMI0 impacts are above PMI0 SILs in suchmunicipalities
By the way neither Taunton Energy nor New Bedford Cogen were built and therefore would not consume PSD increment Any ideas on how to untrigger PMI0 minor source baseline in Taunton and New Bedford assuming it s possible

Steve shy
We go by the date a complete PSD permit application was filed the source need not actually build although where the source does not build
some states have been able to untrigger baseline My review of the Brayton Point case only looked at the Taunton Energy Center- reportedly closest to Somerset - but the plant hardly matters because your 11-1-2008 spreadsheet indicates it is below significant for PM a bit concerned however about the SEMASS (Rochester) and the New Bedford cogen because while they be a bit more distant both wereemissions-significant for PM With impacts below the SILs SEMASS could not set PM baseline area anywhere but in Rochester That leaves the New Bedford cogen as a possible trigger for Somerset PM baseline My review of Dominion s permit modeling concluded that the Somerset baseline area had not been set yet for PM and therefore that only PMemission increases linked to the DSFF control and 2 cooling towers needed to bemodeled for increment consumption wi thin Somerset
The cog en s not more a concern as a trigger for prior incrementconsumption by sources wi thin Somerset than as an increment consumeritself And thanks for your words on selecting nearby sources for interactivemodeling

RE Brayton Point Subj ect
The closest existing PSD source in Massachusetts is SEMASS in Rochester about 10 miles distant Its impacts are below SILs so it would not have to be included in a PSD increment consumption analysis (do youagree Brian)
In the early 90 s there was a PSD application in New Bedford and a PSD application in Taunton - but they were never constructed and therefore wouldn t consume PSD increments (do you agree Brian)
A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

Steve When we talked about the PSD status of the area for Brayton Point you thought that there may have been permits submitted triggering PSD baseline but that these projects have never been built You said you would check with Brian Hennessey at EPA about any other cumulative sources and PSD increment consuming sources in the area of Brayton Pt Have you had a chance to do that We are trying to wrap this up and have assumed so far that there are no interactive sources but confirmation would be helpful Than ks Liz

Subject Somerset Station
Brian
At the request of Scott Lawton of Dominion I am forwarding to you the attached spreadsheet which is a summary of Massachusetts DEP source inventory data for emissions for calendar year 2005 Somerset Station is on row 656 and shows actual emissions of 697083 tons PM10 and 307701 tons PM2
Based on Scott s recollection a reduction in emissions between 2002 and 2005 would be consistent with operational changes that took place at Somerset Station
I found the data you discussed yesterday on the EPA AIRS database I noted that the EPA AIRS
database defines Pollutant Emissions as follows
An emissions estimate is based on the normal operating schedule of a source and includes the effects of installed pollution control equipment and regulatory restrictions on operating conditions This is called estimated emissions with rule effectiveness
Based on that description the data in the EPA AIRS database could be potential emissions rather than actual emissions
The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling

---------------------------------------------------------------------------------------------------------
40 CFR 5221(0) Additional impacts analysis requires an assessment of the impacts on visibility soils and vegetation of emissions from the modification and associated growth
did not require Dominion to assess the visual impact of the cooling towers steam plumes because water vapor and water dropletsaerosols are not pollutants regulated by the Clean Air Act Dominion modeled salt deposition from cooling tower
Region
drif using the nonguideline SA CTI (Seasonal-Annual Cooling Tower Impact) Model
Appendix W is mandatory for concentration calculations not deposition estimates
40 CFR 5221(0) Sources impacting Federal Class I areas requires EPA to give wrtten notice
to the Federal Land Manager of any Class 1 area which the increase in emissions from a major new of modified source may affect
Dominion assessed the impact of the increase in PM emissions at Brayton Point on visibility in the nearest Class I area (Lye Brook Wilderness Vermont) with the
VISCREEN Model The models Levell screen showed no potentialfor visibilty km awayimpairment in the Class 1 area 213
40 CFR 5221(k) Source impact analysis Discussion continued
Tabulated below are the concentration levels relevant to permitting any major new or modified source of PM emissions

PM25 annual air quality standard is-met when the average of the arithmetic annual average over three consecutive years falls below 15 flgmNotes
The PM2 5 24-hour will be met when the 98-tile highest monitored PM2 flgmconcentration averaged over three consecutive years is under 35
The PMI0 24-hour standard is met when the expected number of exceedances of 150 flgm is less than or equalto one
Brayton Point s modeled PM25 and PMI0 impacts above represent maximum anual and 24shy
l)our impacts from the entire plant not merely the increases from the two new cooling towers and DSFF control system on Unit 3 Consequently the next three paragraphs which could have considered PM emission increases alone make highly conservative comparisons against action
levels
SILs or significant impact levels Emissionincreases from new and modified facilities can be permitted in designated attainment areas in the presence of air quality standards violations
40 CFR Parprovided the increase in ambient impacts from the facility fall below these levels
51 Appendix S II tabulates the significance levels Because Brayton Points 24- hour PMI0 impact 219 Jgm
3 exceeds the 5Jgm3 PMI0SIL compliance with increments and air quality standards must be more directly addressed
Monitoring exclusion Because Brayton Points 24- hour 219 Jgm3 PMI0 impact exceeds the 10Jgm3 PMI0 exclusion level the preconstruction monitoring exemption at 40 CFR 5221(i)(5)
does not appear a possibility In any event several recent years ofPMI0 and PM2 representative of the area were available and used in the air qualityanalysis required in 40 CFR
5221(m) as described above Dominion sought no preconstruction monitoring exemption
Increment An increment is the maximum amount by which existing ambient air pollutant concentrations can be allowed to increase thereby approaching an air quality standard 40 CFR 51 166( c) lists the Class IT ambient air increments that apply in Somerset Massachusetts
Because Brayton Points 24- hour 219 Jgm3 PMI0 impact falls below the 30Jgm3 PMI0 3 the increase in PMI0 emission wilincrement and its 17 Jgm anual impact below 17 Jgm
not exceed Class IT increments Note again that most of the emissions Dominion modeled would not result from the modification and do not consume increment
NAAOS The National Ambient Air Quality Standards represent the air pollutant concentrations or levels below which there wil be no adverse effects on health or welfare Compliance with the PM NAAQS is shown by comparing the last line ofthe table which sums
Brayton Points modeled impacts with background PM measurements against the NAAQS appearing in the same column In all cases Total PM concentration falls below the level of and
comply with theNAAQS
The bottom half of the table presents extracts from Dominion s modeling ofPM25 and PMI0 emissions from Brayton Point Note the following all important
Limiting or highest whole source impacts occur at intermediate 10ads (and PM emission rates) - Unit s 1 and 4 operating at 14082250 14082250 35005655 and
24394800 all in units ofmodeled heat input to maximum heat input
Initially modeling compliance against the PM25 and PMl 0 24-hour NAAQS seemed problematic In 2002 Somerset Generating Station (northwest of Brayton Point in the figure above) emitted 199 tpy PM25 and 229 tpy PMI0 Brayton Point s PM impacts approach the two standards and because the increase in Brayton Point s PM emissions
3 SIL(from Unit 3 especially) may cause PM concentration increases over the 5 Jgm(Significant hnpact Level) Dominion should have performed interactive or cumulative PM modeling to include Somerset Generating Station On 14 January AJ Jablonowski
of Epsilon (Dominion s engineering-consultant) e-mailed Region 1 more curent data for Somers t Station showing monotonically decreasing PM emission decreases from 70 tpy PMI0 and 31 tpy PM25 in 2005 to 50 tpy and 23 tpy respectively in 2007 The omission of Somerset from the modeling is in accord with the modeling protocol and acceptable
In an e-mail on 1- 15-2009 Stephen Dennis noted that in permit modellng Massachusetts DEP often requires interactive or cumulative modeling of sources with actual emissions over 100 tpy and within 1 0 km of the permit applicant SomersetStation s PM emissions are lower Note too that Dominion s modeling of Brayton Point has conservatively modeled highest 8 high and highest 2 high model PM2 5 and PMl 0 emissions against the respective PM 24-hour NAAQS where average highest 8 high and highest
high model estimates could have been used The NAAQS analyses also very conservatively assume that monitors record highest PM under conditions corresponding to highest modelled PM impacts

Subject RE Brayton Point
Brian I think we are in agreement
1 The Taunton Energy PSD application did not trigger minor sourcebaseline
for PM10 because a PSD review for PM10 was not required
2 The New Bedford Cogen PSD applications triggered minor sourcebaseline for
PM10 in New Bedford The New Bedford Cogen application didn trigger minor
source baseline anywhere else because its 1 ugm3 PMI0 annual isopleth did
not extend outside New Bedford
3 The SEMASS PSD applications triggered minor source baseline for PMI0
Rochester SEMASS PMI0 impacts are below all PMI0 SILs
4 PMI0 minor source baseline has not yet been triggered in Somerset Dominion
will trigger PMI0 minor source baseline in Somerset and any other municipalities located within its 1 ugm3 annual average PMI0
isopleth
5 Dominion will consume PMI0 increment in Somerset if Dominion PMI0 impacts
are above PMI0 SILs in Somerset Dominion will also consume PMI0 increment
in other municipalities where PM10 baseline has been triggered (such as New
Bedford) if Dominion PMI0 impacts are above PMI0 SILs in suchmunicipalities
By the way neither Taunton Energy nor New Bedford Cogen were built and therefore would not consume PSD increment Any ideas on how to untrigger PMI0 minor source baseline in Taunton and New Bedford assuming it s possible

Steve shy
We go by the date a complete PSD permit application was filed the source need not actually build although where the source does not build
some states have been able to untrigger baseline My review of the Brayton Point case only looked at the Taunton Energy Center- reportedly closest to Somerset - but the plant hardly matters because your 11-1-2008 spreadsheet indicates it is below significant for PM a bit concerned however about the SEMASS (Rochester) and the New Bedford cogen because while they be a bit more distant both wereemissions-significant for PM With impacts below the SILs SEMASS could not set PM baseline area anywhere but in Rochester That leaves the New Bedford cogen as a possible trigger for Somerset PM baseline My review of Dominion s permit modeling concluded that the Somerset baseline area had not been set yet for PM and therefore that only PMemission increases linked to the DSFF control and 2 cooling towers needed to bemodeled for increment consumption wi thin Somerset
The cog en s not more a concern as a trigger for prior incrementconsumption by sources wi thin Somerset than as an increment consumeritself And thanks for your words on selecting nearby sources for interactivemodeling

RE Brayton Point Subj ect
The closest existing PSD source in Massachusetts is SEMASS in Rochester about 10 miles distant Its impacts are below SILs so it would not have to be included in a PSD increment consumption analysis (do youagree Brian)
In the early 90 s there was a PSD application in New Bedford and a PSD application in Taunton - but they were never constructed and therefore wouldn t consume PSD increments (do you agree Brian)
A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

Steve When we talked about the PSD status of the area for Brayton Point you thought that there may have been permits submitted triggering PSD baseline but that these projects have never been built You said you would check with Brian Hennessey at EPA about any other cumulative sources and PSD increment consuming sources in the area of Brayton Pt Have you had a chance to do that We are trying to wrap this up and have assumed so far that there are no interactive sources but confirmation would be helpful Than ks Liz

Subject Somerset Station
Brian
At the request of Scott Lawton of Dominion I am forwarding to you the attached spreadsheet which is a summary of Massachusetts DEP source inventory data for emissions for calendar year 2005 Somerset Station is on row 656 and shows actual emissions of 697083 tons PM10 and 307701 tons PM2
Based on Scott s recollection a reduction in emissions between 2002 and 2005 would be consistent with operational changes that took place at Somerset Station
I found the data you discussed yesterday on the EPA AIRS database I noted that the EPA AIRS
database defines Pollutant Emissions as follows
An emissions estimate is based on the normal operating schedule of a source and includes the effects of installed pollution control equipment and regulatory restrictions on operating conditions This is called estimated emissions with rule effectiveness
Based on that description the data in the EPA AIRS database could be potential emissions rather than actual emissions
The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling

Brayton Point s modeled PM25 and PMI0 impacts above represent maximum anual and 24shy
l)our impacts from the entire plant not merely the increases from the two new cooling towers and DSFF control system on Unit 3 Consequently the next three paragraphs which could have considered PM emission increases alone make highly conservative comparisons against action
levels
SILs or significant impact levels Emissionincreases from new and modified facilities can be permitted in designated attainment areas in the presence of air quality standards violations
40 CFR Parprovided the increase in ambient impacts from the facility fall below these levels
51 Appendix S II tabulates the significance levels Because Brayton Points 24- hour PMI0 impact 219 Jgm
3 exceeds the 5Jgm3 PMI0SIL compliance with increments and air quality standards must be more directly addressed
Monitoring exclusion Because Brayton Points 24- hour 219 Jgm3 PMI0 impact exceeds the 10Jgm3 PMI0 exclusion level the preconstruction monitoring exemption at 40 CFR 5221(i)(5)
does not appear a possibility In any event several recent years ofPMI0 and PM2 representative of the area were available and used in the air qualityanalysis required in 40 CFR
5221(m) as described above Dominion sought no preconstruction monitoring exemption
Increment An increment is the maximum amount by which existing ambient air pollutant concentrations can be allowed to increase thereby approaching an air quality standard 40 CFR 51 166( c) lists the Class IT ambient air increments that apply in Somerset Massachusetts
Because Brayton Points 24- hour 219 Jgm3 PMI0 impact falls below the 30Jgm3 PMI0 3 the increase in PMI0 emission wilincrement and its 17 Jgm anual impact below 17 Jgm
not exceed Class IT increments Note again that most of the emissions Dominion modeled would not result from the modification and do not consume increment
NAAOS The National Ambient Air Quality Standards represent the air pollutant concentrations or levels below which there wil be no adverse effects on health or welfare Compliance with the PM NAAQS is shown by comparing the last line ofthe table which sums
Brayton Points modeled impacts with background PM measurements against the NAAQS appearing in the same column In all cases Total PM concentration falls below the level of and
comply with theNAAQS
The bottom half of the table presents extracts from Dominion s modeling ofPM25 and PMI0 emissions from Brayton Point Note the following all important
Limiting or highest whole source impacts occur at intermediate 10ads (and PM emission rates) - Unit s 1 and 4 operating at 14082250 14082250 35005655 and
24394800 all in units ofmodeled heat input to maximum heat input
Initially modeling compliance against the PM25 and PMl 0 24-hour NAAQS seemed problematic In 2002 Somerset Generating Station (northwest of Brayton Point in the figure above) emitted 199 tpy PM25 and 229 tpy PMI0 Brayton Point s PM impacts approach the two standards and because the increase in Brayton Point s PM emissions
3 SIL(from Unit 3 especially) may cause PM concentration increases over the 5 Jgm(Significant hnpact Level) Dominion should have performed interactive or cumulative PM modeling to include Somerset Generating Station On 14 January AJ Jablonowski
of Epsilon (Dominion s engineering-consultant) e-mailed Region 1 more curent data for Somers t Station showing monotonically decreasing PM emission decreases from 70 tpy PMI0 and 31 tpy PM25 in 2005 to 50 tpy and 23 tpy respectively in 2007 The omission of Somerset from the modeling is in accord with the modeling protocol and acceptable
In an e-mail on 1- 15-2009 Stephen Dennis noted that in permit modellng Massachusetts DEP often requires interactive or cumulative modeling of sources with actual emissions over 100 tpy and within 1 0 km of the permit applicant SomersetStation s PM emissions are lower Note too that Dominion s modeling of Brayton Point has conservatively modeled highest 8 high and highest 2 high model PM2 5 and PMl 0 emissions against the respective PM 24-hour NAAQS where average highest 8 high and highest
high model estimates could have been used The NAAQS analyses also very conservatively assume that monitors record highest PM under conditions corresponding to highest modelled PM impacts

Subject RE Brayton Point
Brian I think we are in agreement
1 The Taunton Energy PSD application did not trigger minor sourcebaseline
for PM10 because a PSD review for PM10 was not required
2 The New Bedford Cogen PSD applications triggered minor sourcebaseline for
PM10 in New Bedford The New Bedford Cogen application didn trigger minor
source baseline anywhere else because its 1 ugm3 PMI0 annual isopleth did
not extend outside New Bedford
3 The SEMASS PSD applications triggered minor source baseline for PMI0
Rochester SEMASS PMI0 impacts are below all PMI0 SILs
4 PMI0 minor source baseline has not yet been triggered in Somerset Dominion
will trigger PMI0 minor source baseline in Somerset and any other municipalities located within its 1 ugm3 annual average PMI0
isopleth
5 Dominion will consume PMI0 increment in Somerset if Dominion PMI0 impacts
are above PMI0 SILs in Somerset Dominion will also consume PMI0 increment
in other municipalities where PM10 baseline has been triggered (such as New
Bedford) if Dominion PMI0 impacts are above PMI0 SILs in suchmunicipalities
By the way neither Taunton Energy nor New Bedford Cogen were built and therefore would not consume PSD increment Any ideas on how to untrigger PMI0 minor source baseline in Taunton and New Bedford assuming it s possible

Steve shy
We go by the date a complete PSD permit application was filed the source need not actually build although where the source does not build
some states have been able to untrigger baseline My review of the Brayton Point case only looked at the Taunton Energy Center- reportedly closest to Somerset - but the plant hardly matters because your 11-1-2008 spreadsheet indicates it is below significant for PM a bit concerned however about the SEMASS (Rochester) and the New Bedford cogen because while they be a bit more distant both wereemissions-significant for PM With impacts below the SILs SEMASS could not set PM baseline area anywhere but in Rochester That leaves the New Bedford cogen as a possible trigger for Somerset PM baseline My review of Dominion s permit modeling concluded that the Somerset baseline area had not been set yet for PM and therefore that only PMemission increases linked to the DSFF control and 2 cooling towers needed to bemodeled for increment consumption wi thin Somerset
The cog en s not more a concern as a trigger for prior incrementconsumption by sources wi thin Somerset than as an increment consumeritself And thanks for your words on selecting nearby sources for interactivemodeling

RE Brayton Point Subj ect
The closest existing PSD source in Massachusetts is SEMASS in Rochester about 10 miles distant Its impacts are below SILs so it would not have to be included in a PSD increment consumption analysis (do youagree Brian)
In the early 90 s there was a PSD application in New Bedford and a PSD application in Taunton - but they were never constructed and therefore wouldn t consume PSD increments (do you agree Brian)
A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

Steve When we talked about the PSD status of the area for Brayton Point you thought that there may have been permits submitted triggering PSD baseline but that these projects have never been built You said you would check with Brian Hennessey at EPA about any other cumulative sources and PSD increment consuming sources in the area of Brayton Pt Have you had a chance to do that We are trying to wrap this up and have assumed so far that there are no interactive sources but confirmation would be helpful Than ks Liz

Following up here is additional information that actual particulate emissions are less than 100 tons at Somerset Station The attached pages from their emission statements show the following annual emissions
2005 69 71 tons PM10 30 77 tons PM2
2006 61 56 tons PM10 2827 tons PM2
2007 50 07 tons PM10 22 97 tons PM2

Subject Somerset Station
Brian
At the request of Scott Lawton of Dominion I am forwarding to you the attached spreadsheet which is a summary of Massachusetts DEP source inventory data for emissions for calendar year 2005 Somerset Station is on row 656 and shows actual emissions of 697083 tons PM10 and 307701 tons PM2
Based on Scott s recollection a reduction in emissions between 2002 and 2005 would be consistent with operational changes that took place at Somerset Station
I found the data you discussed yesterday on the EPA AIRS database I noted that the EPA AIRS
database defines Pollutant Emissions as follows
An emissions estimate is based on the normal operating schedule of a source and includes the effects of installed pollution control equipment and regulatory restrictions on operating conditions This is called estimated emissions with rule effectiveness
Based on that description the data in the EPA AIRS database could be potential emissions rather than actual emissions
The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling

of Epsilon (Dominion s engineering-consultant) e-mailed Region 1 more curent data for Somers t Station showing monotonically decreasing PM emission decreases from 70 tpy PMI0 and 31 tpy PM25 in 2005 to 50 tpy and 23 tpy respectively in 2007 The omission of Somerset from the modeling is in accord with the modeling protocol and acceptable
In an e-mail on 1- 15-2009 Stephen Dennis noted that in permit modellng Massachusetts DEP often requires interactive or cumulative modeling of sources with actual emissions over 100 tpy and within 1 0 km of the permit applicant SomersetStation s PM emissions are lower Note too that Dominion s modeling of Brayton Point has conservatively modeled highest 8 high and highest 2 high model PM2 5 and PMl 0 emissions against the respective PM 24-hour NAAQS where average highest 8 high and highest
high model estimates could have been used The NAAQS analyses also very conservatively assume that monitors record highest PM under conditions corresponding to highest modelled PM impacts

Subject RE Brayton Point
Brian I think we are in agreement
1 The Taunton Energy PSD application did not trigger minor sourcebaseline
for PM10 because a PSD review for PM10 was not required
2 The New Bedford Cogen PSD applications triggered minor sourcebaseline for
PM10 in New Bedford The New Bedford Cogen application didn trigger minor
source baseline anywhere else because its 1 ugm3 PMI0 annual isopleth did
not extend outside New Bedford
3 The SEMASS PSD applications triggered minor source baseline for PMI0
Rochester SEMASS PMI0 impacts are below all PMI0 SILs
4 PMI0 minor source baseline has not yet been triggered in Somerset Dominion
will trigger PMI0 minor source baseline in Somerset and any other municipalities located within its 1 ugm3 annual average PMI0
isopleth
5 Dominion will consume PMI0 increment in Somerset if Dominion PMI0 impacts
are above PMI0 SILs in Somerset Dominion will also consume PMI0 increment
in other municipalities where PM10 baseline has been triggered (such as New
Bedford) if Dominion PMI0 impacts are above PMI0 SILs in suchmunicipalities
By the way neither Taunton Energy nor New Bedford Cogen were built and therefore would not consume PSD increment Any ideas on how to untrigger PMI0 minor source baseline in Taunton and New Bedford assuming it s possible

We go by the date a complete PSD permit application was filed the source need not actually build although where the source does not build
some states have been able to untrigger baseline My review of the Brayton Point case only looked at the Taunton Energy Center- reportedly closest to Somerset - but the plant hardly matters because your 11-1-2008 spreadsheet indicates it is below significant for PM a bit concerned however about the SEMASS (Rochester) and the New Bedford cogen because while they be a bit more distant both wereemissions-significant for PM With impacts below the SILs SEMASS could not set PM baseline area anywhere but in Rochester That leaves the New Bedford cogen as a possible trigger for Somerset PM baseline My review of Dominion s permit modeling concluded that the Somerset baseline area had not been set yet for PM and therefore that only PMemission increases linked to the DSFF control and 2 cooling towers needed to bemodeled for increment consumption wi thin Somerset
The cog en s not more a concern as a trigger for prior incrementconsumption by sources wi thin Somerset than as an increment consumeritself And thanks for your words on selecting nearby sources for interactivemodeling

RE Brayton Point Subj ect
The closest existing PSD source in Massachusetts is SEMASS in Rochester about 10 miles distant Its impacts are below SILs so it would not have to be included in a PSD increment consumption analysis (do youagree Brian)
In the early 90 s there was a PSD application in New Bedford and a PSD application in Taunton - but they were never constructed and therefore wouldn t consume PSD increments (do you agree Brian)
A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

Steve When we talked about the PSD status of the area for Brayton Point you thought that there may have been permits submitted triggering PSD baseline but that these projects have never been built You said you would check with Brian Hennessey at EPA about any other cumulative sources and PSD increment consuming sources in the area of Brayton Pt Have you had a chance to do that We are trying to wrap this up and have assumed so far that there are no interactive sources but confirmation would be helpful Than ks Liz

Subject Somerset Station
Brian
At the request of Scott Lawton of Dominion I am forwarding to you the attached spreadsheet which is a summary of Massachusetts DEP source inventory data for emissions for calendar year 2005 Somerset Station is on row 656 and shows actual emissions of 697083 tons PM10 and 307701 tons PM2
Based on Scott s recollection a reduction in emissions between 2002 and 2005 would be consistent with operational changes that took place at Somerset Station
I found the data you discussed yesterday on the EPA AIRS database I noted that the EPA AIRS
database defines Pollutant Emissions as follows
An emissions estimate is based on the normal operating schedule of a source and includes the effects of installed pollution control equipment and regulatory restrictions on operating conditions This is called estimated emissions with rule effectiveness
Based on that description the data in the EPA AIRS database could be potential emissions rather than actual emissions
The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling

Subject RE Brayton Point
Brian I think we are in agreement
1 The Taunton Energy PSD application did not trigger minor sourcebaseline
for PM10 because a PSD review for PM10 was not required
2 The New Bedford Cogen PSD applications triggered minor sourcebaseline for
PM10 in New Bedford The New Bedford Cogen application didn trigger minor
source baseline anywhere else because its 1 ugm3 PMI0 annual isopleth did
not extend outside New Bedford
3 The SEMASS PSD applications triggered minor source baseline for PMI0
Rochester SEMASS PMI0 impacts are below all PMI0 SILs
4 PMI0 minor source baseline has not yet been triggered in Somerset Dominion
will trigger PMI0 minor source baseline in Somerset and any other municipalities located within its 1 ugm3 annual average PMI0
isopleth
5 Dominion will consume PMI0 increment in Somerset if Dominion PMI0 impacts
are above PMI0 SILs in Somerset Dominion will also consume PMI0 increment
in other municipalities where PM10 baseline has been triggered (such as New
Bedford) if Dominion PMI0 impacts are above PMI0 SILs in suchmunicipalities
By the way neither Taunton Energy nor New Bedford Cogen were built and therefore would not consume PSD increment Any ideas on how to untrigger PMI0 minor source baseline in Taunton and New Bedford assuming it s possible

Steve shy
We go by the date a complete PSD permit application was filed the source need not actually build although where the source does not build
some states have been able to untrigger baseline My review of the Brayton Point case only looked at the Taunton Energy Center- reportedly closest to Somerset - but the plant hardly matters because your 11-1-2008 spreadsheet indicates it is below significant for PM a bit concerned however about the SEMASS (Rochester) and the New Bedford cogen because while they be a bit more distant both wereemissions-significant for PM With impacts below the SILs SEMASS could not set PM baseline area anywhere but in Rochester That leaves the New Bedford cogen as a possible trigger for Somerset PM baseline My review of Dominion s permit modeling concluded that the Somerset baseline area had not been set yet for PM and therefore that only PMemission increases linked to the DSFF control and 2 cooling towers needed to bemodeled for increment consumption wi thin Somerset
The cog en s not more a concern as a trigger for prior incrementconsumption by sources wi thin Somerset than as an increment consumeritself And thanks for your words on selecting nearby sources for interactivemodeling

RE Brayton Point Subj ect
The closest existing PSD source in Massachusetts is SEMASS in Rochester about 10 miles distant Its impacts are below SILs so it would not have to be included in a PSD increment consumption analysis (do youagree Brian)
In the early 90 s there was a PSD application in New Bedford and a PSD application in Taunton - but they were never constructed and therefore wouldn t consume PSD increments (do you agree Brian)
A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

Steve When we talked about the PSD status of the area for Brayton Point you thought that there may have been permits submitted triggering PSD baseline but that these projects have never been built You said you would check with Brian Hennessey at EPA about any other cumulative sources and PSD increment consuming sources in the area of Brayton Pt Have you had a chance to do that We are trying to wrap this up and have assumed so far that there are no interactive sources but confirmation would be helpful Than ks Liz

Subject Somerset Station
Brian
At the request of Scott Lawton of Dominion I am forwarding to you the attached spreadsheet which is a summary of Massachusetts DEP source inventory data for emissions for calendar year 2005 Somerset Station is on row 656 and shows actual emissions of 697083 tons PM10 and 307701 tons PM2
Based on Scott s recollection a reduction in emissions between 2002 and 2005 would be consistent with operational changes that took place at Somerset Station
I found the data you discussed yesterday on the EPA AIRS database I noted that the EPA AIRS
database defines Pollutant Emissions as follows
An emissions estimate is based on the normal operating schedule of a source and includes the effects of installed pollution control equipment and regulatory restrictions on operating conditions This is called estimated emissions with rule effectiveness
Based on that description the data in the EPA AIRS database could be potential emissions rather than actual emissions
The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling

Subject RE Brayton Point
Brian I think we are in agreement
1 The Taunton Energy PSD application did not trigger minor sourcebaseline
for PM10 because a PSD review for PM10 was not required
2 The New Bedford Cogen PSD applications triggered minor sourcebaseline for
PM10 in New Bedford The New Bedford Cogen application didn trigger minor
source baseline anywhere else because its 1 ugm3 PMI0 annual isopleth did
not extend outside New Bedford
3 The SEMASS PSD applications triggered minor source baseline for PMI0
Rochester SEMASS PMI0 impacts are below all PMI0 SILs
4 PMI0 minor source baseline has not yet been triggered in Somerset Dominion
will trigger PMI0 minor source baseline in Somerset and any other municipalities located within its 1 ugm3 annual average PMI0
isopleth
5 Dominion will consume PMI0 increment in Somerset if Dominion PMI0 impacts
are above PMI0 SILs in Somerset Dominion will also consume PMI0 increment
in other municipalities where PM10 baseline has been triggered (such as New
Bedford) if Dominion PMI0 impacts are above PMI0 SILs in suchmunicipalities
By the way neither Taunton Energy nor New Bedford Cogen were built and therefore would not consume PSD increment Any ideas on how to untrigger PMI0 minor source baseline in Taunton and New Bedford assuming it s possible

Steve shy
We go by the date a complete PSD permit application was filed the source need not actually build although where the source does not build
some states have been able to untrigger baseline My review of the Brayton Point case only looked at the Taunton Energy Center- reportedly closest to Somerset - but the plant hardly matters because your 11-1-2008 spreadsheet indicates it is below significant for PM a bit concerned however about the SEMASS (Rochester) and the New Bedford cogen because while they be a bit more distant both wereemissions-significant for PM With impacts below the SILs SEMASS could not set PM baseline area anywhere but in Rochester That leaves the New Bedford cogen as a possible trigger for Somerset PM baseline My review of Dominion s permit modeling concluded that the Somerset baseline area had not been set yet for PM and therefore that only PMemission increases linked to the DSFF control and 2 cooling towers needed to bemodeled for increment consumption wi thin Somerset
The cog en s not more a concern as a trigger for prior incrementconsumption by sources wi thin Somerset than as an increment consumeritself And thanks for your words on selecting nearby sources for interactivemodeling

RE Brayton Point Subj ect
The closest existing PSD source in Massachusetts is SEMASS in Rochester about 10 miles distant Its impacts are below SILs so it would not have to be included in a PSD increment consumption analysis (do youagree Brian)
In the early 90 s there was a PSD application in New Bedford and a PSD application in Taunton - but they were never constructed and therefore wouldn t consume PSD increments (do you agree Brian)
A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

Steve When we talked about the PSD status of the area for Brayton Point you thought that there may have been permits submitted triggering PSD baseline but that these projects have never been built You said you would check with Brian Hennessey at EPA about any other cumulative sources and PSD increment consuming sources in the area of Brayton Pt Have you had a chance to do that We are trying to wrap this up and have assumed so far that there are no interactive sources but confirmation would be helpful Than ks Liz

Following up here is additional information that actual particulate emissions are less than 100 tons at Somerset Station The attached pages from their emission statements show the following annual emissions
2005 69 71 tons PM10 30 77 tons PM2
2006 61 56 tons PM10 2827 tons PM2
2007 50 07 tons PM10 22 97 tons PM2

Subject Somerset Station
Brian
At the request of Scott Lawton of Dominion I am forwarding to you the attached spreadsheet which is a summary of Massachusetts DEP source inventory data for emissions for calendar year 2005 Somerset Station is on row 656 and shows actual emissions of 697083 tons PM10 and 307701 tons PM2
Based on Scott s recollection a reduction in emissions between 2002 and 2005 would be consistent with operational changes that took place at Somerset Station
I found the data you discussed yesterday on the EPA AIRS database I noted that the EPA AIRS
database defines Pollutant Emissions as follows
An emissions estimate is based on the normal operating schedule of a source and includes the effects of installed pollution control equipment and regulatory restrictions on operating conditions This is called estimated emissions with rule effectiveness
Based on that description the data in the EPA AIRS database could be potential emissions rather than actual emissions
The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling

Subject RE Brayton Point
Brian I think we are in agreement
1 The Taunton Energy PSD application did not trigger minor sourcebaseline
for PM10 because a PSD review for PM10 was not required
2 The New Bedford Cogen PSD applications triggered minor sourcebaseline for
PM10 in New Bedford The New Bedford Cogen application didn trigger minor
source baseline anywhere else because its 1 ugm3 PMI0 annual isopleth did
not extend outside New Bedford
3 The SEMASS PSD applications triggered minor source baseline for PMI0
Rochester SEMASS PMI0 impacts are below all PMI0 SILs
4 PMI0 minor source baseline has not yet been triggered in Somerset Dominion
will trigger PMI0 minor source baseline in Somerset and any other municipalities located within its 1 ugm3 annual average PMI0
isopleth
5 Dominion will consume PMI0 increment in Somerset if Dominion PMI0 impacts
are above PMI0 SILs in Somerset Dominion will also consume PMI0 increment
in other municipalities where PM10 baseline has been triggered (such as New
Bedford) if Dominion PMI0 impacts are above PMI0 SILs in suchmunicipalities
By the way neither Taunton Energy nor New Bedford Cogen were built and therefore would not consume PSD increment Any ideas on how to untrigger PMI0 minor source baseline in Taunton and New Bedford assuming it s possible

Steve shy
We go by the date a complete PSD permit application was filed the source need not actually build although where the source does not build
some states have been able to untrigger baseline My review of the Brayton Point case only looked at the Taunton Energy Center- reportedly closest to Somerset - but the plant hardly matters because your 11-1-2008 spreadsheet indicates it is below significant for PM a bit concerned however about the SEMASS (Rochester) and the New Bedford cogen because while they be a bit more distant both wereemissions-significant for PM With impacts below the SILs SEMASS could not set PM baseline area anywhere but in Rochester That leaves the New Bedford cogen as a possible trigger for Somerset PM baseline My review of Dominion s permit modeling concluded that the Somerset baseline area had not been set yet for PM and therefore that only PMemission increases linked to the DSFF control and 2 cooling towers needed to bemodeled for increment consumption wi thin Somerset
The cog en s not more a concern as a trigger for prior incrementconsumption by sources wi thin Somerset than as an increment consumeritself And thanks for your words on selecting nearby sources for interactivemodeling

RE Brayton Point Subj ect
The closest existing PSD source in Massachusetts is SEMASS in Rochester about 10 miles distant Its impacts are below SILs so it would not have to be included in a PSD increment consumption analysis (do youagree Brian)
In the early 90 s there was a PSD application in New Bedford and a PSD application in Taunton - but they were never constructed and therefore wouldn t consume PSD increments (do you agree Brian)
A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

Steve When we talked about the PSD status of the area for Brayton Point you thought that there may have been permits submitted triggering PSD baseline but that these projects have never been built You said you would check with Brian Hennessey at EPA about any other cumulative sources and PSD increment consuming sources in the area of Brayton Pt Have you had a chance to do that We are trying to wrap this up and have assumed so far that there are no interactive sources but confirmation would be helpful Than ks Liz

Following up here is additional information that actual particulate emissions are less than 100 tons at Somerset Station The attached pages from their emission statements show the following annual emissions
2005 69 71 tons PM10 30 77 tons PM2
2006 61 56 tons PM10 2827 tons PM2
2007 50 07 tons PM10 22 97 tons PM2

Subject Somerset Station
Brian
At the request of Scott Lawton of Dominion I am forwarding to you the attached spreadsheet which is a summary of Massachusetts DEP source inventory data for emissions for calendar year 2005 Somerset Station is on row 656 and shows actual emissions of 697083 tons PM10 and 307701 tons PM2
Based on Scott s recollection a reduction in emissions between 2002 and 2005 would be consistent with operational changes that took place at Somerset Station
I found the data you discussed yesterday on the EPA AIRS database I noted that the EPA AIRS
database defines Pollutant Emissions as follows
An emissions estimate is based on the normal operating schedule of a source and includes the effects of installed pollution control equipment and regulatory restrictions on operating conditions This is called estimated emissions with rule effectiveness
Based on that description the data in the EPA AIRS database could be potential emissions rather than actual emissions
The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling

Subject RE Brayton Point
Brian I think we are in agreement
1 The Taunton Energy PSD application did not trigger minor sourcebaseline
for PM10 because a PSD review for PM10 was not required
2 The New Bedford Cogen PSD applications triggered minor sourcebaseline for
PM10 in New Bedford The New Bedford Cogen application didn trigger minor
source baseline anywhere else because its 1 ugm3 PMI0 annual isopleth did
not extend outside New Bedford
3 The SEMASS PSD applications triggered minor source baseline for PMI0
Rochester SEMASS PMI0 impacts are below all PMI0 SILs
4 PMI0 minor source baseline has not yet been triggered in Somerset Dominion
will trigger PMI0 minor source baseline in Somerset and any other municipalities located within its 1 ugm3 annual average PMI0
isopleth
5 Dominion will consume PMI0 increment in Somerset if Dominion PMI0 impacts
are above PMI0 SILs in Somerset Dominion will also consume PMI0 increment
in other municipalities where PM10 baseline has been triggered (such as New

By the way neither Taunton Energy nor New Bedford Cogen were built and therefore would not consume PSD increment Any ideas on how to untrigger PMI0 minor source baseline in Taunton and New Bedford assuming it s possible

Steve shy
We go by the date a complete PSD permit application was filed the source need not actually build although where the source does not build
some states have been able to untrigger baseline My review of the Brayton Point case only looked at the Taunton Energy Center- reportedly closest to Somerset - but the plant hardly matters because your 11-1-2008 spreadsheet indicates it is below significant for PM a bit concerned however about the SEMASS (Rochester) and the New Bedford cogen because while they be a bit more distant both wereemissions-significant for PM With impacts below the SILs SEMASS could not set PM baseline area anywhere but in Rochester That leaves the New Bedford cogen as a possible trigger for Somerset PM baseline My review of Dominion s permit modeling concluded that the Somerset baseline area had not been set yet for PM and therefore that only PMemission increases linked to the DSFF control and 2 cooling towers needed to bemodeled for increment consumption wi thin Somerset
The cog en s not more a concern as a trigger for prior incrementconsumption by sources wi thin Somerset than as an increment consumeritself And thanks for your words on selecting nearby sources for interactivemodeling

RE Brayton Point Subj ect
The closest existing PSD source in Massachusetts is SEMASS in Rochester about 10 miles distant Its impacts are below SILs so it would not have to be included in a PSD increment consumption analysis (do youagree Brian)
In the early 90 s there was a PSD application in New Bedford and a PSD application in Taunton - but they were never constructed and therefore wouldn t consume PSD increments (do you agree Brian)
A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

Steve When we talked about the PSD status of the area for Brayton Point you thought that there may have been permits submitted triggering PSD baseline but that these projects have never been built You said you would check with Brian Hennessey at EPA about any other cumulative sources and PSD increment consuming sources in the area of Brayton Pt Have you had a chance to do that We are trying to wrap this up and have assumed so far that there are no interactive sources but confirmation would be helpful Than ks Liz

Subject Somerset Station
Brian
At the request of Scott Lawton of Dominion I am forwarding to you the attached spreadsheet which is a summary of Massachusetts DEP source inventory data for emissions for calendar year 2005 Somerset Station is on row 656 and shows actual emissions of 697083 tons PM10 and 307701 tons PM2
Based on Scott s recollection a reduction in emissions between 2002 and 2005 would be consistent with operational changes that took place at Somerset Station
I found the data you discussed yesterday on the EPA AIRS database I noted that the EPA AIRS
database defines Pollutant Emissions as follows
An emissions estimate is based on the normal operating schedule of a source and includes the effects of installed pollution control equipment and regulatory restrictions on operating conditions This is called estimated emissions with rule effectiveness
Based on that description the data in the EPA AIRS database could be potential emissions rather than actual emissions
The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling

Subject RE Brayton Point
Brian I think we are in agreement
1 The Taunton Energy PSD application did not trigger minor sourcebaseline
for PM10 because a PSD review for PM10 was not required
2 The New Bedford Cogen PSD applications triggered minor sourcebaseline for
PM10 in New Bedford The New Bedford Cogen application didn trigger minor
source baseline anywhere else because its 1 ugm3 PMI0 annual isopleth did
not extend outside New Bedford
3 The SEMASS PSD applications triggered minor source baseline for PMI0
Rochester SEMASS PMI0 impacts are below all PMI0 SILs
4 PMI0 minor source baseline has not yet been triggered in Somerset Dominion
will trigger PMI0 minor source baseline in Somerset and any other municipalities located within its 1 ugm3 annual average PMI0
isopleth
5 Dominion will consume PMI0 increment in Somerset if Dominion PMI0 impacts
are above PMI0 SILs in Somerset Dominion will also consume PMI0 increment
in other municipalities where PM10 baseline has been triggered (such as New
Bedford) if Dominion PMI0 impacts are above PMI0 SILs in suchmunicipalities
By the way neither Taunton Energy nor New Bedford Cogen were built and therefore would not consume PSD increment Any ideas on how to untrigger PMI0 minor source baseline in Taunton and New Bedford assuming it s possible

Steve shy
We go by the date a complete PSD permit application was filed the source need not actually build although where the source does not build
some states have been able to untrigger baseline My review of the Brayton Point case only looked at the Taunton Energy Center- reportedly closest to Somerset - but the plant hardly matters because your 11-1-2008 spreadsheet indicates it is below significant for PM a bit concerned however about the SEMASS (Rochester) and the New Bedford cogen because while they be a bit more distant both wereemissions-significant for PM With impacts below the SILs SEMASS could not set PM baseline area anywhere but in Rochester That leaves the New Bedford cogen as a possible trigger for Somerset PM baseline My review of Dominion s permit modeling concluded that the Somerset baseline area had not been set yet for PM and therefore that only PMemission increases linked to the DSFF control and 2 cooling towers needed to bemodeled for increment consumption wi thin Somerset
The cog en s not more a concern as a trigger for prior incrementconsumption by sources wi thin Somerset than as an increment consumeritself And thanks for your words on selecting nearby sources for interactivemodeling

RE Brayton Point Subj ect
The closest existing PSD source in Massachusetts is SEMASS in Rochester about 10 miles distant Its impacts are below SILs so it would not have to be included in a PSD increment consumption analysis (do youagree Brian)
In the early 90 s there was a PSD application in New Bedford and a PSD application in Taunton - but they were never constructed and therefore wouldn t consume PSD increments (do you agree Brian)
A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

Steve When we talked about the PSD status of the area for Brayton Point you thought that there may have been permits submitted triggering PSD baseline but that these projects have never been built You said you would check with Brian Hennessey at EPA about any other cumulative sources and PSD increment consuming sources in the area of Brayton Pt Have you had a chance to do that We are trying to wrap this up and have assumed so far that there are no interactive sources but confirmation would be helpful Than ks Liz

Following up here is additional information that actual particulate emissions are less than 100 tons at Somerset Station The attached pages from their emission statements show the following annual emissions
2005 69 71 tons PM10 30 77 tons PM2
2006 61 56 tons PM10 2827 tons PM2
2007 50 07 tons PM10 22 97 tons PM2

Subject Somerset Station
Brian
At the request of Scott Lawton of Dominion I am forwarding to you the attached spreadsheet which is a summary of Massachusetts DEP source inventory data for emissions for calendar year 2005 Somerset Station is on row 656 and shows actual emissions of 697083 tons PM10 and 307701 tons PM2
Based on Scott s recollection a reduction in emissions between 2002 and 2005 would be consistent with operational changes that took place at Somerset Station
I found the data you discussed yesterday on the EPA AIRS database I noted that the EPA AIRS
database defines Pollutant Emissions as follows
An emissions estimate is based on the normal operating schedule of a source and includes the effects of installed pollution control equipment and regulatory restrictions on operating conditions This is called estimated emissions with rule effectiveness
Based on that description the data in the EPA AIRS database could be potential emissions rather than actual emissions
The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling

Subject RE Brayton Point
Brian I think we are in agreement
1 The Taunton Energy PSD application did not trigger minor sourcebaseline
for PM10 because a PSD review for PM10 was not required
2 The New Bedford Cogen PSD applications triggered minor sourcebaseline for
PM10 in New Bedford The New Bedford Cogen application didn trigger minor
source baseline anywhere else because its 1 ugm3 PMI0 annual isopleth did
not extend outside New Bedford
3 The SEMASS PSD applications triggered minor source baseline for PMI0
Rochester SEMASS PMI0 impacts are below all PMI0 SILs
4 PMI0 minor source baseline has not yet been triggered in Somerset Dominion
will trigger PMI0 minor source baseline in Somerset and any other municipalities located within its 1 ugm3 annual average PMI0
isopleth
5 Dominion will consume PMI0 increment in Somerset if Dominion PMI0 impacts
are above PMI0 SILs in Somerset Dominion will also consume PMI0 increment
in other municipalities where PM10 baseline has been triggered (such as New
Bedford) if Dominion PMI0 impacts are above PMI0 SILs in suchmunicipalities
By the way neither Taunton Energy nor New Bedford Cogen were built and therefore would not consume PSD increment Any ideas on how to untrigger PMI0 minor source baseline in Taunton and New Bedford assuming it s possible

Steve shy
We go by the date a complete PSD permit application was filed the source need not actually build although where the source does not build
some states have been able to untrigger baseline My review of the Brayton Point case only looked at the Taunton Energy Center- reportedly closest to Somerset - but the plant hardly matters because your 11-1-2008 spreadsheet indicates it is below significant for PM a bit concerned however about the SEMASS (Rochester) and the New Bedford cogen because while they be a bit more distant both wereemissions-significant for PM With impacts below the SILs SEMASS could not set PM baseline area anywhere but in Rochester That leaves the New Bedford cogen as a possible trigger for Somerset PM baseline My review of Dominion s permit modeling concluded that the Somerset baseline area had not been set yet for PM and therefore that only PMemission increases linked to the DSFF control and 2 cooling towers needed to bemodeled for increment consumption wi thin Somerset
The cog en s not more a concern as a trigger for prior incrementconsumption by sources wi thin Somerset than as an increment consumeritself And thanks for your words on selecting nearby sources for interactivemodeling

RE Brayton Point Subj ect
The closest existing PSD source in Massachusetts is SEMASS in Rochester about 10 miles distant Its impacts are below SILs so it would not have to be included in a PSD increment consumption analysis (do youagree Brian)
In the early 90 s there was a PSD application in New Bedford and a PSD application in Taunton - but they were never constructed and therefore wouldn t consume PSD increments (do you agree Brian)
A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

Steve When we talked about the PSD status of the area for Brayton Point you thought that there may have been permits submitted triggering PSD baseline but that these projects have never been built You said you would check with Brian Hennessey at EPA about any other cumulative sources and PSD increment consuming sources in the area of Brayton Pt Have you had a chance to do that We are trying to wrap this up and have assumed so far that there are no interactive sources but confirmation would be helpful Than ks Liz

Subject Somerset Station
Brian
At the request of Scott Lawton of Dominion I am forwarding to you the attached spreadsheet which is a summary of Massachusetts DEP source inventory data for emissions for calendar year 2005 Somerset Station is on row 656 and shows actual emissions of 697083 tons PM10 and 307701 tons PM2
Based on Scott s recollection a reduction in emissions between 2002 and 2005 would be consistent with operational changes that took place at Somerset Station
I found the data you discussed yesterday on the EPA AIRS database I noted that the EPA AIRS
database defines Pollutant Emissions as follows
An emissions estimate is based on the normal operating schedule of a source and includes the effects of installed pollution control equipment and regulatory restrictions on operating conditions This is called estimated emissions with rule effectiveness
Based on that description the data in the EPA AIRS database could be potential emissions rather than actual emissions
The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling

Subject RE Brayton Point
Brian I think we are in agreement
1 The Taunton Energy PSD application did not trigger minor sourcebaseline
for PM10 because a PSD review for PM10 was not required
2 The New Bedford Cogen PSD applications triggered minor sourcebaseline for
PM10 in New Bedford The New Bedford Cogen application didn trigger minor
source baseline anywhere else because its 1 ugm3 PMI0 annual isopleth did
not extend outside New Bedford
3 The SEMASS PSD applications triggered minor source baseline for PMI0
Rochester SEMASS PMI0 impacts are below all PMI0 SILs
4 PMI0 minor source baseline has not yet been triggered in Somerset Dominion
will trigger PMI0 minor source baseline in Somerset and any other municipalities located within its 1 ugm3 annual average PMI0
isopleth
5 Dominion will consume PMI0 increment in Somerset if Dominion PMI0 impacts
are above PMI0 SILs in Somerset Dominion will also consume PMI0 increment
in other municipalities where PM10 baseline has been triggered (such as New
Bedford) if Dominion PMI0 impacts are above PMI0 SILs in suchmunicipalities
By the way neither Taunton Energy nor New Bedford Cogen were built and therefore would not consume PSD increment Any ideas on how to untrigger PMI0 minor source baseline in Taunton and New Bedford assuming it s possible

Steve shy
We go by the date a complete PSD permit application was filed the source need not actually build although where the source does not build
some states have been able to untrigger baseline My review of the Brayton Point case only looked at the Taunton Energy Center- reportedly closest to Somerset - but the plant hardly matters because your 11-1-2008 spreadsheet indicates it is below significant for PM a bit concerned however about the SEMASS (Rochester) and the New Bedford cogen because while they be a bit more distant both wereemissions-significant for PM With impacts below the SILs SEMASS could not set PM baseline area anywhere but in Rochester That leaves the New Bedford cogen as a possible trigger for Somerset PM baseline My review of Dominion s permit modeling concluded that the Somerset baseline area had not been set yet for PM and therefore that only PMemission increases linked to the DSFF control and 2 cooling towers needed to bemodeled for increment consumption wi thin Somerset
The cog en s not more a concern as a trigger for prior incrementconsumption by sources wi thin Somerset than as an increment consumeritself And thanks for your words on selecting nearby sources for interactivemodeling

RE Brayton Point Subj ect
The closest existing PSD source in Massachusetts is SEMASS in Rochester about 10 miles distant Its impacts are below SILs so it would not have to be included in a PSD increment consumption analysis (do youagree Brian)
In the early 90 s there was a PSD application in New Bedford and a PSD application in Taunton - but they were never constructed and therefore wouldn t consume PSD increments (do you agree Brian)
A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

Steve When we talked about the PSD status of the area for Brayton Point you thought that there may have been permits submitted triggering PSD baseline but that these projects have never been built You said you would check with Brian Hennessey at EPA about any other cumulative sources and PSD increment consuming sources in the area of Brayton Pt Have you had a chance to do that We are trying to wrap this up and have assumed so far that there are no interactive sources but confirmation would be helpful Than ks Liz

Subject Somerset Station
Brian
At the request of Scott Lawton of Dominion I am forwarding to you the attached spreadsheet which is a summary of Massachusetts DEP source inventory data for emissions for calendar year 2005 Somerset Station is on row 656 and shows actual emissions of 697083 tons PM10 and 307701 tons PM2
Based on Scott s recollection a reduction in emissions between 2002 and 2005 would be consistent with operational changes that took place at Somerset Station
I found the data you discussed yesterday on the EPA AIRS database I noted that the EPA AIRS
database defines Pollutant Emissions as follows
An emissions estimate is based on the normal operating schedule of a source and includes the effects of installed pollution control equipment and regulatory restrictions on operating conditions This is called estimated emissions with rule effectiveness
Based on that description the data in the EPA AIRS database could be potential emissions rather than actual emissions
The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling

The closest existing PSD source in Massachusetts is SEMASS in Rochester about 10 miles distant Its impacts are below SILs so it would not have to be included in a PSD increment consumption analysis (do youagree Brian)
In the early 90 s there was a PSD application in New Bedford and a PSD application in Taunton - but they were never constructed and therefore wouldn t consume PSD increments (do you agree Brian)
A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

A MassDEP search for nearby sources that could significantly interact with Brayton point - typically defined by MassDEP as 100 ton sources within 10 km (actual emissions) and 1000 ton sources within 20 km (actual emissions) indicated that there were no such sources for PM10 and PM2 5

To
Steve When we talked about the PSD status of the area for Brayton Point you thought that there may have been permits submitted triggering PSD baseline but that these projects have never been built You said you would check with Brian Hennessey at EPA about any other cumulative sources and PSD increment consuming sources in the area of Brayton Pt Have you had a chance to do that We are trying to wrap this up and have assumed so far that there are no interactive sources but confirmation would be helpful Than ks Liz

At the request of Scott Lawton of Dominion I am forwarding to you the attached spreadsheet which is a summary of Massachusetts DEP source inventory data for emissions for calendar year 2005 Somerset Station is on row 656 and shows actual emissions of 697083 tons PM10 and 307701 tons PM2
Based on Scott s recollection a reduction in emissions between 2002 and 2005 would be consistent with operational changes that took place at Somerset Station
I found the data you discussed yesterday on the EPA AIRS database I noted that the EPA AIRS
database defines Pollutant Emissions as follows
An emissions estimate is based on the normal operating schedule of a source and includes the effects of installed pollution control equipment and regulatory restrictions on operating conditions This is called estimated emissions with rule effectiveness
Based on that description the data in the EPA AIRS database could be potential emissions rather than actual emissions
The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling

The information we have available to us indicates that actual emissions for Somerset Station are below 100 tons per year PM1 0 and PM2 5 Per our air quality modeling protocol we did not include Somerset Station in any interactive modeling
