Enclosure:1. Responses to Air Quality Questions from October 7, 2009 NRC Request for Additional
Information
GE Hitachi
Enclosure 1 Response to Air Quality RAIs
4-6 Air Quality Impacts: A. Provide additional information, specified below, on air emission inventories expected during
road construction, site preparation (pre-construction), construction, and operation of the proposed GLE facility.
1. Provide anticipated PM2.5 emissions expected during road construction, site preparation (pre-construction), construction, and operation of the proposed GLE facility.
2. To facilitate the evaluation of impacts on global climate change, provide greenhouse gas emissions (e.g., CO2) associated with the site preparation (pre-construction), construction, and operation activities for the proposed GLE facility.
3. Provide emissions of criteria pollutants, including both PM10 and PM2.5, during facility operation from: (1) the GLE mechanical-draft cooling tower; (2) cylinder-handling activities (e.g., diesel-powered gantry or fork lift) between the main GLE buildings and cylinder pads; and (3) hauling traffic of product cylinders between the GLE facility and other facilities at the Wilmington Site.
4. Provide air emissions of criteria pollutants, including both PM10 and PM2.5, by pollutant and by source category (similar to ER Table 4.6-1) along with emission factors, activity levels, and control efficiencies for road construction, site preparation (pre-construction), construction, and operation of the proposed GLE facility.
The air emissions estimates for construction and operation of the Proposed GLE Facility have been updated. The air emissions estimates are provided below in two sections. The first section presents the air emissions estimates for the criteria air pollutants: particulate matter (PM) (both the PM10 and PM2.5 categories), nitrogen oxides (NOx), sulfur dioxide (SO2), volatile organic compounds (VOC), and carbon monoxide (CO). The following section presents air emissions estimates for greenhouse gases.
Criteria Air Pollutant Emissions
Separate sets of criteria air pollutant emissions were made for four phases of the Proposed GLE Facility project.
Proposed GLE Facility Early Construction (Year 2011).
Proposed GLE Facility Building Construction (Year 2012).
Proposed GLE Facility Final Construction/Startup (Years 2013-2017).
Proposed GLE Facility Operation (Years 2018-2048)
The emission factors, activity levels, control efficiencies, and other assumptions used for each set of air emissions estimates are presented in Tables 4-6-1 through 4-6-4. For each identified parameter, the parameter value selected for the emissions estimates is identified and the basis for the value selection is described. The Proposed GLE Facility design, construction schedule, and operating plans have not been finalized at this time. To provide upper bound estimates of the criteria air emissions from each of the GLE Facility project phases for the purpose of assessing air quality impacts, conservative values for were used for those
2
site-specific parameters for which definitive values are not available at this time in the project development (i.e., the assumed vales were selected such that air emissions estimates would be maximized for a given air emission source). Examples of these parameters include the period of time required to complete a construction activity such as site preparation and mix of off-road construction equipment operated at the site to complete the activity... The estimates for average daily and average annual criteria air pollutant emissions from the specific sources associated with each of the Proposed GLE Facility project phases are presented in Tables 4-6-5 through4-6-8.
The emission estimates for the Proposed GLE Facility phases with construction activities (Tables 4-6-5 through 4-6-7) indicate the largest source of criteria air emissions are PM emissions from fugitive dust generated by outdoor construction activities during the Early Construction and Building Construction Phases. Small quantities of NOx, SO2, VOC, and CO emissions are released by the off-road construction equipment needed for construction activities and from the construction worker automobiles and construction material trucks traveling to and from the Proposed GLE Facility project site.
The emission estimates for the Operation Phase (Table 4-6-8) indicate that the Proposed GLE Facility would not be a major source of any criteria air pollutant as defined under U.S. Environmental Protection Agency (EPA) or North Carolina Division of Air Quality (NC DAQ) air permitting requirements. The laser uranium-enrichment process would be conducted totally indoors inside the main GLE operations building. Most of the heat generated by the process lasers would be used for the building interior space heating and to meet other process-heat demands. The only stationary combustion sources planned to be installed at the Proposed GLE Facility would be auxiliary diesel generator units. The other notable criteria air pollutant emissions sources at the Proposed GLE Facility would be 1) the PM emissions from mechanical draft cooling towers, 2) emissions from the motor vehicles operated for onsite for the handling and transport of UF6 cylinders, and 3) automobile and truck traffic associated with the GLE Facility operations. Other small, miscellaneous sources of criteria air pollutant emissions are described in Section 4.6.2.2.1.3 of the GLE ER.
Greenhouse Gas Emissions
The greenhouse gas (GHG) emissions associated with the GLE Facility project primarily are from the mobile and stationary combustion sources that operate during each of the project phases. Over 90% of the GHG emissions released by combustion sources are carbon dioxide (CO2). Smaller quantities of methane (CH4) and nitrous oxide (N2O) are also emitted from combustion sources. Average annual estimates of the CO2, CH4, and N2O emissions from each phase of the Proposed GLE Facility project were calculated by multiplying the estimated volume of fuel consumed for each combustion source type by an appropriate fuel-specific GHG emission factor. There are no significant sources of hydofluorocarbons (HFCs) associated with the Proposed GLE Facility laser uranium-enrichment process. There is the limited potential for some releases of HFCs from leakage and recharging of air conditioning systems used for office and other related interior spaces in Proposed GLE Facility buildings.
The estimates for the average annual GHG emissions from the specific sources associated with each of the Proposed GLE Facility project phases are presented in Table 4-6-9.The GHG estimates for off-road construction equipment presented for the Early Construction and Building Construction Phases are based on the very conservative assumption that the entire mix of off-road construction equipment assumed for the phase (see Tables 4-6-1 and4-6-2 respectively) operates the entire day of every day of the construction period. In actuality, different of combinations of the assumed off-road equipment would be for different stages of construction (i.e., not all of the assumed equipment always would be onsite at the same time)
3
Consequently, actual off-road equipment diesel fuel consumption and consequently the GHG emissions from the Proposed GLE Facility construction phases are expected to be lower that the estimated levels indicated in Table 4-6-9.
B. Provide air dispersion modeling for operational emission sources such as auxiliary diesel generator units, cooling tower, and onsite traffic. No air dispersion modeling during facility operation was included in the ER.
A new air dispersion modeling analysis for the Proposed GLE Facility using the AERMOD model has been performed with a new set of assumptions based on the updated information regarding the Proposed GLE Facility design, local metrological data, and the new set of criteria air pollutant emissions estimates presented in Tables 4-6-5 through 4-6-8. The results of new air dispersion modeling for each of the four Proposed GLE Facility phases are presented in Tables 4-6-12 through 4-6-16. The air dispersion modeling for the Operation Phase presented in Table 4-6-16 includes emissions from the Proposed GLE Facility auxiliary diesel generator units, cooling tower, and onsite traffic. The predicted maximum off-site concentrations presented in Tables 4-6-12 through 4-6-16 include ambient background concentrations for the pollutants for which ambient air monitoring data are available (see Tables 4-6-10 and 4-6-11).
The new air monitoring results predict maximum off-site concentrations resulting from the Proposed GLE Facility criteria air pollutant emissions to be less than the level of the comparable ambient air quality standard with the exception of the 24-hour average PM concentrations predicted for the Early Construction and Building Construction Phases. The 24-hour average PM concentration results for the air dispersion modeling are discussed further below in the response to RAI 4-6-D.
C. Provide additional information, specified below, to justify AERMOD modeling choices or provide updated AERMOD analyses taking into account the comments and recommendations listed below. The AERMOD model was used to estimate potential air quality impacts as reported in the ER, but independent analyses conducted by NRC noted discrepancies that diverge from typical air impact modeling practices.
1. Clarification is needed of the unit emission rates that were multiplied by actual emissions. For example, the emission rate for site preparation was estimated to be 1.15 × 10-4
lb/ft2/work hour (in GLE_construction_phase_emission_factor.xls) but the value is listed as 1.15 × 10-4 lb/ft2/work day in the summary worksheet which, in turn, was used for the final results. Clarify which unit emission rate is correct and revise the results if necessary.
As discussed above in the Response to RAI 4-6-B, a new air dispersion analysis has been performed for the Proposed GLE Facility. The emission rates referenced in this question no longer apply to the air dispersion analysis, and should be disregarded.
2. In reporting model results, include background concentrations representative of the Wilmington Site.
As discussed in the Response to RAI 4-6-B, the predicted maximum off-site concentrations from the new air dispersion analysis for the Proposed GLE Facility presented in Tables 4-6-12 through 4-6-16 include ambient background concentrations for the pollutants for which ambient air monitoring data are available. Tables 4-6-10 and 4-6-11 are updated
4
versions of tables originally presented in GLE ER Section 3.6 that include ambient air quality monitoring data that was measured by the NC DAQ at monitoring stations in New Hanover County, NC, and was reported to EPA’s Air Quality System (AQS) for the years 2007 and 2009. Ambient PM10 monitoring data representative of the Proposed GLE Facility site are available from the AQS only for the months of February and March in 2008 (see Tables 4-6-10 and4-6-11).
3. Provide additional justification of the use of meteorological data from the Wilmington Airport in the AERMOD model or revise the model using data from a site with surface conditions representative of both the measurement and application sites.
Meteorological data used in the AERMOD model were reprocessed using “onsite” data from the nearby Horticultural Crop Research Station in Castle Hayne, NC. National Weather Service observations from the Wilmington International Airport were used to supplement the “onsite” data, where data were incomplete at the Crop Research Station. Surface roughness length, Bowen ratio, and albedo were estimated based on National Land Cover Data (NLCD) 1992 land cover data for the area surrounding the Crop Research Station, which is considered the primary meteorological data. The wet, dry, average estimation which is used for Bowen ratio, however, is based on 30 years of climate data for the Wilmington International Airport, obtained from the National Climatic Data Center, because the Crop Research Station did not have data for a full 30 year period of record to perform this estimation.
4. Provide a justification for the dry and wet deposition used in the PM10 modeling or provide an air dispersion modeling analysis with 1) PM10 conservatively assumed to act as a gas and 2) no dry and wet deposition.
The new modeling analysis was run for both PM10 and PM2.5. While dry and wet deposition were not calculated for the final results, the concentration results were calculated assuming that dry and wet depletion of the plume does take place. While it is correct that neglecting depletion would result in a higher, more conservative, PM10 and PM2.5 concentrationresult, fugitive dust from construction activities would be released at ground level. Gravitational settling, interaction with the ground and vegetation, and precipitation events would be expected to deplete the plume, therefore applying plume depletion should give a more realistic concentration result.
5. Provide a justification as to why the most recent five years of data from the Wilmington International Airport and Morehead City/Newport, North Carolina stations were not used in the analysis or re-perform the analysis using more recent data.
Meteorological data used in the new dispersion modeling analysis were based on 5 years of surface data from Wilmington International Airport, upper air data from Charleston International Airport, and “onsite” data from the Horticultural Crop Research Station , which is immediately east of the GE-Wilmington Site. The years chosen for this analysis were 2000, 2002, 2003, 2005, and 2006. The data for 2001 were not used due to the inability of the AERMET preprocessor to process the upper air data without error, while 2004 was discarded due to AERMET being unable to produce meteorological files for the complete year of data.1
The data selected for this analysis is considered to be representative of the variability expected 1 Surface data from 2007 and 2008 were not available as part of the dataset ordered to complete the GLE ER Document[0].
5
in the local weather conditions for the years in which the proposed site preparation and construction of the Proposed GLE Facility would take place, since the data are from recent years and climate conditions have little variability over the short term.
Charleston International Airport was chosen as the upper air station over Beaufort-Morehead City Airport after considering the similarities in climatologic and geographic setting. The specific reasons for selecting Charleston International Airport are:
Charleston International Airport was chosen as the upper air station over Beaufort-Morehead City Airport after considering the similarities in climatologic and geographic setting. The specific reasons for selecting Charleston International Airport are:
Charleston International Airport is more similar in distance inland to the application site and Wilmington International Airport, than Beaufort-Morehead City Airport. Charleston International Airport lies approximately 14 miles from the ocean, while Morehead City’s airport is only about 3 miles from the ocean. The application site lies approximately 11 miles inland, and the Wilmington International Airport is about 7 to 8 miles inland. This will affect the timing of boundary layer development, as well as that of the sea breeze frontal passage.
Beaufort-Morehead City Airport is on a peninsula and thus surrounded by water. Charleston International Airport is inland, having a similar setting to the application site and Wilmington International Airport. The proximity of large waterbodies and geographic setting will affect the meteorological conditions.
The orientation of the coastline near the application site and Wilmington International Airport is approximately the same as it is at Charleston International Airport. However, Beaufort-Morehead City Airport is near a coastline with a very different orientation, which will affect the direction from which sea breeze related wind blows at the upper air station.
Based on Climate data obtained from the National Climatic Data Center, Charleston International Airport has similar wind speeds when compared month by month to that of Wilmington International Airport. Wind speeds at the Beaufort-Morehead City Airport are dissimilar to those measured at the Wilmington International Airport. The wind direction measured at Charleston is similar to that measured at the Wilmington International Airport, than Beaufort-Morehead City Airport when compared on a month by month basis.
6. Clarify which settings were used to obtain both 24-hour and annual average concentrations and revise the model input parameters to use information representing conditions from 7 a.m. to 4 p.m. of weekends as well as weekdays if necessary.
The new AERMOD runs use the HROFDY keyword, which allows the user to vary the emission source strength by time. For these runs it is assumed that the workers would work for 9 hours per day, starting at 7 AM. Therefore, the multiplier was set to 0.0 for the first 6 hours, 1.0 for the next 9 hours starting at 7 AM, and 0.0 for the last 9 hours of each day. Weekends were included as work days.
7. Determine surface moisture conditions used to calculate the Bowen ratio based on the 30-year climatological data for the Wilmington airport (e.g., 1971-2000 normals if 2004-2008
6
meteorological data are used) or provide additional justification for the use of wet surface moisture conditions to calculate the ratio.
Surface moisture used to calculate the Bowen ratio was determined for each individual year used in modeling. This was accomplished by comparing each year’s total amount of precipitation based on National Weather Service observations at the Wilmington International Airport against a distribution of precipitation probabilities for 30 years of climate data, accessed on-line from the National Climatic Data Center (http://www.ncdc.noaa.gov/oa/ncdc.html).
D. With a typical control efficiency of 50% from water spraying for fugitive dust emissions, preliminary independent analysis conducted by NRC indicates that the total (background plus modeled) 24-hour concentration at the northern site boundaries could exceed the ambient air quality standard during site preparation. Reexamine the assumptions and modeling parameters used to estimate the air quality impacts at these locations and specify the dust control measures that will be used to mitigate the impacts.
The assumptions used to estimate impacts from fugitive dust emissions generated by construction activities for the Proposed GLE Facility project have been reviewed and updated as presented in Table 4-6-1 and 4-6-2. Using these updated assumptions and the new PM emissions estimates presented in Tables 4-6-5 and 4-6-6 based on these assumptions, new air dispersion modeling was performed that included results to assess the 24-hour average ambient PM10 and PM2.5 concentration impacts at the northern site boundaries for the Proposed GLE Facility. The predicted maximum off-site 24-hour average ambient PM10 and PM2.5concentrations including ambient PM background concentrations based on the new air dispersion analysis for the Proposed GLE Facility are presented in Tables 4-6-12 through4-6-16 for the four Proposed GLE Facility phases
Ambient PM10 monitoring data for EPA’s Air Quality System database applicable to the Wilmington Site are available only for February and March, 2008 (see Tables 4-6-10 and4-6-11). Insufficient data are available to determine annual average PM10 concentration. Furthermore, PM2.5 is a fraction of the PM10 concentrations in the ambient air (i.e., the measured PM10 concentration includes the concentration of PM2.5 in the ambient air). Therefore, the long-term average PM10 concentration cannot less than the long-term PM2.5 concentrations measured at a site. Review of the available PM10 ambient monitoring data summarized in Table 4-6-11 shows that the highest 24-hour PM10 concentration measured in February and March, 2008 (21 μg/m3) is less than the long-term 24-hour average PM2.5 concentration (24 μg/m3). For the purpose of including a credible order-of-magnitude estimate of the existing PM10 background concentrations to assess off-site ambient PM10 concentrations resulting from activities at the Proposed GLE Facility, the long-term 24-hour and annual average PM2.5 long-term concentrations presented in Table 4-6-1 are used to the represent PM10 background concentrations. This assumption is made recognizing that the corresponding the actual long-term ambient PM10 concentrations for the site would be somewhat higher.
Compliance with ambient air quality standards is determined by long-term ambient air quality monitoring at predetermined monitoring station locations using methods and analysis procedures established by EPA for the federal ambient air quality standards and the NC DAQ for the state ambient air quality standards. The ambient are standards are not intended to be used for direct assessment of localized ambient air pollutant concentrations from temporary emission sources such as construction projects. However, the comparison of the predicted air dispersion modeling ambient concentrations with the appropriate ambient air quality standard levels presented in Tables 4-6-11 through 4-6-15 do provide an order-of-magnitude indicator of
7
any potential air quality impacts from the Proposed GLE Facility construction and operation activities.
The air dispersion modeling results based on a conservative set of assumptions indicate that the predicted maximum 24-hour average PM10 concentrations from construction activities associated with the Early Construction and Building Construction Phases at certain times may exceed a level of 150 μg/m3 at off-site locations adjacent to the Wilmington Site property boundary. The specific predicted maximum off-site 24-hour average ambient PM10 and PM2.5concentration values shown in Tables 4-6-12 and 4-6-14 are considered to be upper bound estimates because of the set of conservative assumptions used for the construction practices occurring during the Proposed GLE Facility Early Construction and Building Construction Phases. The predicted 24-hour average concentrations represent a day on which construction activity is occurring continuously throughout the Proposed GLE Facility site (e.g., earthmoving operations are being conducted and the soil is being actively disturbed over the entire approximately 148 acre site continuously for the entire 9-hour construction work day). To this scenario is applied the PM10 emission factor for worst-case conditions (0.42 ton/acre/month). Worst-case conditions are defined for application of this emission factor to be those construction sites with active large-scale earth moving operations. In actuality, this assumed construction scenario is likely to occur for only for short durations or not all at the Proposed GLE Facility site with construction activity typically being concentrated in a potion of the project site on any given work day.
Because of the predicted maximum off-site 24-hour average ambient PM10 and PM2.5concentration values from the air dispersion modeling, the potential for localized temporary fugitive dust impacts from Proposed GLE Facility was further investigated. Table 4-6-13presents the predicted maximum off-site 24-hour average ambient PM10 and PM2.5concentrations (including ambient background concentrations) that would occur with the construction of the onsite access road to the Proposed GLE Facility site. This activity is assumed to be complete with the first 30 days of the Early Construction Period before site preparation work begins on the Proposed GLE Facility Site. The air dispersion modeling results in Table 4-6-13 show predicted maximum off-site 24-hour average ambient PM10 and PM2.5concentrations below the levels of the corresponding PM ambient air quality standards.
The high predicted maximum off-site 24-hour average ambient PM10 and PM2.5concentration values shown in Tables 4-6-12 and 4-6-14 occur at receptors on the Wilmington Site boundary very near the Proposed GLE Facility site. At the off-site receptor location identified at nearest existing residence along the Wilmington Site northern boundary the predicted maximum off-site 24-hour average ambient PM10 and PM2.5 concentration values are significantly lower. The predicted maximum off-site 24-hour average ambient PM10 and PM2.5concentration values at this off-site location are as follows:
While the assumptions used for air dispersion analysis likely overstate the actual maximum 24-hour average PM10 and PM2.5 concentrations that would occur from construction activities associated with the Proposed GLE Facility Early Construction and Building
8
Construction Phase, the magnitude of the predicted PM concentrations do suggest that there is at least the potential for levels of fugitive dust emission generated by certain shot-term construction activities at the Proposed GLE Facility site to temporarily impact existing neighborhoods located adjacent to the northeast boundary of the Wilmington Site.
Implementation of fugitive dust control practices at large construction sites reduce the levels of PM emissions actually released to the atmosphere. During the Proposed GLE Facility construction phases, good practice fugitive dust control measures for construction sites would be implemented to mitigate fugitive dust emissions impacts. These control measures would include:
Periodic watering of the areas of Proposed GLE Facility site where construction activities actively disturb the soil to reduce generation of fugitive dust from such activities, as dictated by site weather conditions.
Periodic watering of the unpaved portions of the onsite access road as needed depending to reduce dust generated by motor vehicle traffic on the roadway, as dictated by site weather conditions..
Limiting vehicle speeds on the unpaved portions of the onsite access road and within the construction site to less than 15 mph to reduce dust generated by motor vehicle traffic on the roadway.
Removing dirt from truck tires by driving over a gravel pad prior to leaving the Proposed GLE Facility site or unpaved access road to avoid spreading sediments on paved roads.
Covering trucks carrying soil and debris to reduce dust emissions from the back of trucks driving on onsite and public roadways.
Completing paving of the entire length of the Proposed GLE Facility onsite access road and the parking lots as soon as practicable.

Reference: North Carolina Division of Air Quality, Available at < http://daq.state.nc.us/monitor/> a Name commonly used in NC DAQ documents to refer to site location. Note that while one of the stations is referred to as
the New Hanover County station, all of the monitoring stations listed in the table are located in New Hanover County. b Special purpose SO2 monitor is operated at the Castle Hayne station January 1 to through December 31 every third year.
This monitor was last operated at the Castle Hayne station in 2005 and is scheduled to operate next at the site in 2008. c The NC-DAQ began monitoring for PM10 in the Wilmington MSA at the Castle Hayne site in February 2008 to collect data
to use for PSD modeling for the coastal region. The Castle Hayne monitor was shut down on March 31, 2008, because of a wildfire in the vicinity of the monitoring site. The PM10 monitor was removed and relocated to a monitoring site outside of New Hanover County (Kenansville, NC) in January 2009.
d Monitoring station is located next to a sulfuric acid manufacturing facility in a unincorporated area of New Hanover County.
e Monitoring station shut down after 2004. f Monitoring station is near the USS North Carolina memorial near the City of Wilmington downtown district.g NC DAQ monitors for selected organic compounds from the EPA hazardous air pollutant (HAP) and NC DAQ toxic air
pollutant (TAP) lists. HAPs and TAPs are not criteria air pollutants with ambient air quality standards.
