Response to Talking Points Regarding the Environmental Report 

1. RAI 8 – (Air Emissions during Construction / Estimated Emission Off Road Equipment) Provide 

additional information regarding air emissions during construction of the IIFP facility. 

a. Provide the site-specific assumptions that went into the estimates of the air emissions 

resulting from operation of off-road construction equipment in Table 4-11 of the ER (IIFP, 

2009a). Include vehicle types and assumptions regarding quantity totals that make up the 

thirteen support vehicles and the thirteen construction vehicles. 

 Discussion: 

The draft response to request for additional information (RAI) 8a identified the assumed quantity 

for each type of construction equipment/vehicle listed in Tables RAI 8-a-1 and RAI 8-a-13. The 

final response to RAI 8a omitted this information. 

Clarification: 

Were the equipment quantities assumed in the draft response used to calculate the monthly 

horsepower-hours listed in Tables RAI 8-a-1 and RAI 8-a-13 of the final response? If not, please 

provide the correct quantity for each type of construction equipment / vehicle listed. 

Goal: 

Equipment quantities are needed to verify the applicant’s assumptions and to more accurately 

estimate potential emissions. 

RESPONSE: 

The final response to RAI 8a also identified thirteen construction vehicles and twelve support 

vehicles for Phase 1 construction. However, four welders have been added to that listing making 

29 construction/support vehicles. The final response to RAI 8a also identified 14 pieces of 

equipment for Phase 2 construction. 

Fifteen pieces of equipment are needed during pre-construction. The makeup and quantities of 

that equipment are shown in Table D-2 “Pre-construction Equipment Quantities by Month” in the 

attached Appendix D” “Non-Radiological Emissions and Impacts for Phase 1 and Phase 2 

Construction Activities.” The makeup and quantities of the construction/support vehicles used in 

Phase 1 construction during the first 12 months of construction are shown in Table D-3. It is 

anticipated that the greatest air emissions would be generated during the first few months of the 

first year when the large pieces of earthmoving equipment would be used. For Phase 2 

construction, the makeup and quantities of equipment anticipated to be involved in construction 

activities during the 12 months of construction are shown in Table D-4. 

(Note: Tables designated as “D-” in this Talking Points response will be located in new Appendix 

D of the ER). 

The Environmental Report will be revised to reflect the construction equipment for preconstruction and the additional construction equipment for Phase 1 construction. 

Environmental Report Impact: The Environmental Report will be revised to reflect the 

construction equipment for pre-construction and the additional construction equipment for Phase 

1 construction. See the Environmental Report Impact for item #4 
Response to Talking Points Regarding the Environmental Report (Item 1) Page 2 

Environmental Report Impact: It is now envisioned that pre-construction can start the first 

quarter of 2012 and the NRC license will be granted late in the second quarter of 2012. Phase 1 

construction would be initiated soon after the license is received. The schedule submitted in the 

final RAI response will be amended as below and will replace Table 1-2 of the Environmental 

Report, Revision A:

revised to include the pre-construction equipment and the addition equipment for Phase 1 

construction. See the 4th paragraph of Section 4.6.1.1 shown in the Environmental Report Impact for 

item #4. 
Response to Talking Points Regarding the Environmental Report (Item 2) Page 3 

2. RAI 8a - (Same as above) 

 Discussion: 

We are unable to verify the horsepower-hours (hp-hrs) per month provided in Tables RAI 8-a-1 

and RAI 8-a-13 of the final RAI response. The revised Environmental Report (ER) indicates that 

emission rates were estimated for a 10-hour workday assuming peak construction activity levels 

were maintained throughout the year. This equates to 208 hours per month. However, the values 

in Tables RAI 8-a-1 and RAI 8-a-13 are less than the values that would be calculated using 208 

hours per month. 

Clarification: 

Please provide the monthly hours of operation for each type of construction equipment/vehicle 

listed in Tables RAI 8-a-1 and RAI 8-a-13. 

Goal: 

The monthly hours of operation for construction equipment are needed to verify the applicant’s 

assumptions and to more accurately estimate potential emissions. 

RESPONSE: 

The maximum number of monthly hours of operation for any equipment item in Phase 1 was 

estimated at 160 hours. Table D-5 shows the hours of operation for each equipment item used to 

provide emission data for Tables RAI 8-a-1 through RAI 8-a-12 for Pre-construction and Phase 1 

construction. Table D-7 provides the Pre-construction/Phase 1 equipment estimated horsepowerhours per month. Pre-construction includes months 01 through 03, while Phase 1 construction 

includes months 04 through 15. Additionally, the maximum number of monthly hours of 

operation for any equipment item for Phase 2 was estimated at 160 hours. Table D-6 show the 

hours of operation for each equipment item used to provide emission data for Tables RAI 8-a-13 

through RAI 8-a-22 for Phase 2 construction. Table D-8 provides the Phase 2 equipment 

estimated horsepower-hours per month. 

Environmental Report Impact: A draft of Chapter 4 of the Environmental Report, Revision B 

was submitted to the NRC with the transmittal of the ER RAIs. Table 4-13 of the draft 

Environmental Report, Revision B, will be updated to add an assumption that the maximum hour 

of operation for each piece of equipment is 160 hours/month as below, see Table 4-13 in the 

Environmental Report Impact for item #4 

Environmental Report Impact: Assumption item (1) will be added to Table 4-23 (also Table D53) of the draft Chapter 4 of the Environmental Report for the maximum hours of operation of 

each unit of equipment as shown in Environmental Report Impact for item #4 (Section 4.6.3.1). 
Response to Talking Points Regarding the Environmental Report (Item 3) Page 4 

3. RAI 8a - (Same as above) 

A. Discussion: 

The revised ER Section 4.6 states that construction in Phase 1 will last approximately 18 to 

24 months. 

Clarification:

Does this timeframe include preconstruction? 

RESPONSE: 

This timeframe includes pre-construction. In these responses to Talking Points, Months 01 

through 03 are for Pre-construction and months 04 through 15 are for Phase 1 construction. 

See Tables D-13 through D-15 for pre-construction emissions data and Tables D-16 through 

D-27 for Phase 1 construction emissions data. Additional months may be necessary for Phase 

1 construction, but these months are not included in these responses since the calculation of 

peak annual emissions will occur during the initial months when large earthmoving 

equipment is used. Tables D-28 through D-39 provide the emissions data for Phase 2 

construction. 

Environmental Report Impact: None. 

B. Discussion: 

Tables RAI 8-a-1 and RAI 8-a-2 of the final RAI responses cover a 12-month period during 

Phase 1 construction. The timing of this 12-month period within the overall 18 to 24 month 

Phase 1 construction timeframe is unclear. 

Clarification: 

Please clarify the timing of this 12-month period within the overall 18 to 24 month Phase 1 

construction timeframe. Also, please provide assumptions for Phase I construction emissions 

that would occur outside the 12-month period described in Tables RAI 8-a-1 and RAI 8-a-2 

(e.g., emissions would decrease after the 12 months provided because...). 

Goal: 

Assumptions and calculations are needed to verify the applicant’s assumptions and to more 

accurately estimate potential emissions. 

RESPONSE: 

The first 12 months of construction was assumed to the worst-case scenario (maximum 

annual emissions and impacts) since the large earthmoving equipment would be used during 

the initial months. Using the first 12 months (months 1 through 3 for pre-construction and 

months 4 through 15 of Phase 1) would result in the peak annual emission and impacts of the 

various criteria pollutants. Table D-40 presents the pollutant and CO2 emissions for preconstruction and Phase 1 construction. See Table D-41 for emissions data for preconstruction, Phase 1 construction, and worst-case construction year. 

Environmental Report Impact: None. 
Response to Talking Points Regarding the Environmental Report (Item 4) Page 5 

4. RAI 8a - (Same as above) 

 Discussion: 

We are unable to verify the emission factors provided in Table RAI 8-a-2 of the final RAI 

response. The revised ER Chapter 4, states that emission factors from FERC Docket PF06-13-

000 and EPA-420-R-10-018 were used to estimate emissions of criteria pollutants and nonmethane hydrocarbons from construction support vehicles and equipment. And AP-42 emission 

factors for diesel-powered construction equipment were used to estimate the total suspended 

particulates for these vehicles. But Table RAI 8-a-2 of the final RAI response indicates that the 

values listed are AP-42 non-road emission factors for diesel-fired equipment with transient 

adjustment and deterioration factors applied. AP-42 emission factors for non-road sources are 

from work performed in the 1970s and EPA stopped using those emission factors in 1991. EPA 

currently recommends using their NONROAD model to estimate emissions from construction 

equipment and other non-road sources. EPA-420-R-10-018 (ER reference EPA 2010) is a 

technical report that describes and documents the development of exhaust emission factors used 

for compression ignition (CI) engines in the EPA’s NONROAD2008a emission inventory model. 

Clarification: 

Was the NONROAD model used to develop emission factors for the construction equipment or 

were emission factors from AP-42 used? 

If the NONROAD model was used, please provide the copies of the model runs, including input 

assumptions and output tables. 

If AP-42 or another document was used, please provide a copy of the reference document(s) and 

justification for its use. (AP-42 Volume II, which contains the emission factors for nonroad 

mobile sources is no longer available on the EPA website.) Also, please provide the original 

(unadjusted) emission factors, the transient adjustment factors, the deterioration factors, and the 

equations used to adjust the emission factors. 

Goal:

It is not clear what assumptions, calculations, or sources were used for the emission factors. The 

model runs, assumptions, and output tables are to more accurately estimate potential emissions. 

RESPONSE: 

As described in the User Manual, the EPA NONROAD model was specifically developed to 

assist states and local regulatory agencies across the U.S.A. in the creation of accurate emissions 

inventories to demonstrate compliance with the Clean Air Act. As such, the NONROAD 

computer model may apply some assumptions that are not necessarily representative of the IIFP 

project. Therefore, to achieve the most accurate results, construction emissions were instead 

calculated based on the data and analytic methods published in [1] EPA-420-P-04-009, “Exhaust 

and Crankcase Emission Factors for Nonroad Engine Modeling – Compression Ignition” (EPA 

2004b) and [2] “EPA-420-P-04-005, Median Life, Annual Activity, and Load Factor Values for 

Nonroad Engine Emissions Modeling” (EPA 2004c). These documents are readily available for 

public download in PDF format at the websites listed below:

Response to Talking Points Regarding the Environmental Report (Item 4) Page 6 

To develop the Phase 1 construction emissions calculations, a list of anticipated construction 

equipment (and rated horsepower) was developed. An EPA Standard Classification Code was 

then identified for each equipment item, and an appropriate load factor was selected from EPA420-P-04-005. A data table was then prepared to identify the estimated hours of operation for 

each equipment item, by month, for the initial twelve months of construction. The monthly 

horsepower-hours for each equipment item were then calculated as a product of the maximum 

equipment horsepower, load factor, and estimated hours of operation. 

Equipment-specific pollutant emission rates (in units of grams per horsepower-hour), and the 

Brake Specific Fuel Consumption (BSFC), were then determined based on the analytic methods 

described in EPA-420-P-04-009 (Tier 1 was assumed for all construction equipment). In general, 

the EPA-420-P-04-009 methods (1) postulate a zero-hour steady state emission factor (EFss) for 

construction equipment and (2) present equations to adjust each EFss based on a Transient 

Adjustment Factor (TAF) and a Deterioration Factor (DF). Monthly pollutant emissions for each 

equipment item were then calculated as a product of the monthly horsepower-hours and the 

equipment-specific pollutant emission rates (Note: The list of anticipated construction equipment 

includes light, medium, and delivery trucks. Although these types of vehicles are frequently used 

at construction sites, these vehicles are not considered "off-road" and therefore do not have an 

off-road standard classification code. For simplicity, the horsepower and load factor of a backhoe, 

standard classification code 2270002066, was conservatively assumed for these vehicles). See 

Table D-9 for the EFss for the construction equipment (Pre-construction, Phase 1 and Phase 2 

construction). The TAFs are shown in Table D-10. Table D-11 presents the BSFCs for all the 

construction equipment and the Spm rates for all equipment types. D-12 (RAI Table 8-a-2) 

presents the equipment specific emission rates. For each month of the year, the quantity and 

average monthly hours of operation for each equipment item was estimated. Based on the 

equipment horsepower, load factor, equipment quantities, hours of operation, and pollutant 

emission factors, the total monthly emissions for each pollutant and each equipment item are 

calculated by Equation 01. 

Tailpipe 

Emissions, g = 

(Emissions Factor, g/hp-hr) × (horsepower, hp) × (load factor) 

× (equipment quantity, each) × (hours operated, hrs) 

[EQN_01] 

Annual construction emissions were then determined as a sum of the monthly emissions for each

Environmental Report Impact: The draft Chapter 4, Revision B, of the Environmental Report 

Section 4.6.1.1, the 4th and sequence paragraphs, will be changed to incorporate the above 

clarification. 

4.6.1.1 Air Quality Impacts from Pre-construction/Phase 1 Construction 

An estimate of the air emissions resulting fromattributable to operation of the off-road 

construction equipment at the IIFP facility site was made using the site-specific assumptions. The 

estimated air emissions for the off-road construction equipment used at the IIFP facility site are 

presented in Table 4-13. 

Emission rates from vehicle exhaust and fugitive dust, as listed in Table 4-13, “NAAQS Criteria 

Pollutant, VOC, and HAP Emission Rates during Pre-construction/Phase 1 Construction,” were 

estimated for a 10-hour workday assuming peak construction activity levels were maintained 

throughout the yearbased on assumed equipment activity levels for each month. Fugitive dust will 

originate predominantly from vehicle traffic on unpaved surfaces, earth moving, excavating and 

bulldozing, and to a lesser extent from wind erosion. It was assumed that the total disturbed area 

of the site was 16.2 ha (40 ac) and that Pre-construction would span for 3 months, followed by 12 

additional months of Phase 1 construction. Phase 2 construction is assumed to span for one year.

the construction in Phase 1 will last approximately 18 to 24 months and Phase 2 construction will 

last approximately one year. Some of the equipment will be utilized the entire time, some will be 

sequential, and others may be only intermittent. 

Of the combustion sources, vehicle exhaust will be the dominant source. Fugitive volatile 

emissions will also occur because diesel vehicles will be refueled on site. Estimated vehicles that 

will be operatingoperate on the site during construction consist of two types: support vehicles and 

construction equipment. The support vehicles included 12 miscellaneous diesel vehicles and 

equipment. Emission factors from the Federal Energy Regulatory Commission (FERC) Docket 

PF06-13-000 (FERC, 2006) and from EPA-420-R-10-018 (EPA, 2010) for highway mobile 

sources were used to estimate emissions of criteria pollutants and non-methane hydrocarbons for 

these vehicles. To achieve the most accurate results, construction emissions attributable to diesel

Assumptions:

1. Annual construction activities are performed 50 hours per week for 50 weeks. Maximum hours of operation of any piece of 

equipment isare 160 hours/month.

2. Peak site preparation activities persist for 4 months in the first year.

3. Post site-preparation activities persist for 7.5 months in the first year.next 11 months

4. Fugitive dust emissions are calculated separately for peak site preparation and post site-preparation.

5. Fugitive TSP generation is 1.2 ton/acre/month for peak site preparation.

6. Fugitive TSP generation is 0.3 ton/acre/month for the 3.25 months after site preparation is completed.

7. Fugitive PM10 emissions are 15 percent of TSP.

8. Fugitive PM2.5 emissions are 7.5 percent of TS.P

9. The site is 40 acres.

10. Sixty percent of the 40 acre site is disturbed at any given time.

11. The disturbed area at any time has the same aspect ratio as the IIFP site (aspect ratio = 1.3).

12. Sixty percent of construction equipment is operational at any given time.

13. Application of water on unpaved surfaces reduces fugitive dust by 50 percent.

14. All construction equipment is fueled with diesel.

15. Construction equipment emission factors based on EPA AP-42load factors are based on EPA-420-P-04-005.

16. Construction equipment emission factors and deterioration factors are based on EPA420-P-04-009,

fuel combustion were calculated based on the data and analytic methods published in [1] EPA420-P-04-009, “Exhaust and Crankcase Emission Factors for Nonroad Engine Modeling –

Compression Ignition” (EPA, 2004b) and [2] “EPA-420-P-04-005, Median Life, Annual 

Activity, and Load Factor Values for Nonroad Engine Emissions Modeling” (EPA, 2004c). 

Fifteen pieces of equipment are needed for the pre-construction of the IIFP Facility. For Phase 1 

construction, Thirteen29 pieces of miscellaneous construction equipment were used to estimate 

the emissions. For Phase 2 construction, 14 pieces of equipment were used to estimate emissions.

Emission factors provided in AP-42, the U.S. Environmental Protection Agency's Compilation of 

Air Pollutant Emission Factors (EPA, 2009a) for diesel-powered construction equipment were 

used to estimate the total suspended particulates for these vehicles. Pre-construction activities will 
Response to Talking Points Regarding the Environmental Report (Item 4) Page 9 

reduce the work density and lower the concentration of air emissions at any given time. The gross 

amount of emissions will be unaffected.

Diesel fuel will be stored on site during construction and will be hand pumped into construction 

vehicles and other plant vehicles involved in construction. The fuel tanks will be stored on a 

containment-type pad, and trucks will be driven onto the containment-type pad to start the 

dispensing process. The pad will be sloped and curbed. The above ground fuel storage and 

dispensing apparatus is self-contained and includes a support frame on which a fuel storage tank 

is mounted and surrounded by a fuel containment vessel. 

Air quality impacts from site preparation for the IIFP Facility were evaluated using emission 

factors and air dispersion modeling. Emission rates of Clean Air Act Criteria Pollutants and nonmethane hydrocarbons (a precursor of ozone, a Criteria Pollutant) are estimated for exhaust 

emissions from construction vehicles and for fugitive dust using emission factor's provided in 

AP-42, the U.S. Environmental Protection Agency's Compilation of Air Pollutant Emission 

Factors (EPA, 2009a). 

Fugitive HAP emissions are generated by evaporative losses from diesel storage tanks and diesel 

fuel transfer operations. The total annual HAP fugitive emissions are calculated as a product of 

the diesel consumption factors from AP-42 (EPA, 2009a), and an HAP fugitive emission rate of 

0.000028 lb fugitive HAPs per lb diesel (SBAP, 2010). Annual pollutant emission totals (tailpipe 

emissions + fugitive dust emissions + fugitive HAP emissions) are summed. Annual pollutant 

emission totals form the basis for calculation of the average emission rate for input to SCREEN3. 

Similarly, monthly maximum criteria pollutant emissions are summed, and the maximum sum is 

selected to calculate time-averaged area emission rates for input to SCREEN3. The SCREEN3 

computer program is applied to estimate maximum regional criteria pollutant concentrations 

attributable to area source construction emissions (i.e., air quality impacts). Air quality impacts 

are not evaluated for HAPs or VOCs because there are no regulatory metrics for comparison 

(HAP and VOC emissions are regulated by source controls and permit requirements). SCREEN3 

calculates the one-hour average concentration for a range of downwind distances. Key inputs 

include the pollutant emission rate (g/s/m3), release height (m), receptor height (m), stability 

class, and wind speed (m/s). All construction emissions are conservatively assumed to originate at 

ground level.

Emissions were estimated in ISCST3 as a uniform area source with emissions occurring 10 hours 

per day, 5 days per week, and 50 weeks per year. The maximum predicted air concentrations 

during /pre-construction/Phase 1 construction at the site fence boundary for the various averaging 

periods predicted using five years (1987 to 1991) of hourly meteorological data from the 

Midland-Odessa, Texas, National Weather Service (NWS) station are presented in Table 4-142.

These concentrations are compared to the appropriate National Ambient Air Quality Standard 

(NAAQS). 

The results of air modeling show that annual average and short-term ambient air concentrations 

from fugitive dust and on-site motor vehicle emissions produced by construction activities for the 

IIFP Facility will be orders of magnitude below the level of the applicable ambient air quality 

standards. Peak year VOC and HAP emissions attributable to construction are 1.8 0.9 tons and 

1.0 0.5 ton, respectively. These emissions are negligible compared to annual VOC and HAP 

emissions in Lea County. These incremental air quality impacts from the air emissions from 

preparation of the IIFP facility site and construction of the facility will not measurably change the 

existing ambient air quality in the vicinity of the IIFP Facility; therefore, the air quality impacts

Assumptions:

1. Pollutant impacts are determined based on the peak emissions generated by site preparation. 

2. The peak one-hour concentrations are as determined by SCREEN3.

3. To determine the peak 3-hour concentration, the peak one-hour concentration is scaled by 0.9 based on EPA guidance on 

EPA guidance.

4. To determine the peak 8-hour concentration, the peak one-hour concentration is scaled by 0.7 based on EPA guidance.

5. To determine the peak 24-hour concentration, the peak one-hour concentration is scaled by 0.4 based on EPA guidance 

and by 10/24 to account for limited work day.

6. To determine the peak annual concentration, the peak one-hour concentration is scaled by 0.07 based on EPA guidance, 

by 10/24 to account for limited work day, then adjusted to account for 4 months of peak emissions (site preparation), 7.5 

months of reduced emissions (post site preparation), and two weeks of zero emissions.

resulting from the preconstruction and general construction stages of the IIFP Facility are 

anticipated to be SMALL. 

Pollutant emissions and diesel fuel consumption attributable to construction activities were 

estimated based on the anticipated types and sizes of construction equipment, monthly hours of 

operation, EPA AP-42 emission factors, and fugitive dust emission rates of 1.2 and 0.3 tons of 

total suspended particulate per acre of construction area per month for initial site preparation and 

post-site preparation activities, respectively. Annual totals for Pre-construction/Phase 1 include

combustion of 778,000 pounds(109,848 gallons) of diesel fuel which would generate VOC and 

HAP emissions of 1,6061,770 pounds and 981 1,065 pounds, respectively. VOC fugitive losses 

attributable to diesel fuel storage and transfer operations are estimated at 22 pounds, for an annual 

VOC emission total of 1,6281,792 pounds. The annual VOC/HAP emissions for Lea County NM 

are on the order of 5.4 million pounds. VOC/HAP emissions attributable to IIFP Phase 1 

construction activities represent a very small fraction of the present regional emissions. 

Therefore, the air quality impacts attributable to construction activities and operation of an on-site 

diesel fuel station would be SMALL.

b. Describe how the on-site fueling of gasoline and diesel vehicles will take place.

c. Provide air impact analysis for the fuel storage and dispensing activities.

 Discussion: 

In the revised ER, all gas powered vehicles and construction equipment have been removed. 

Clarification: 

Is this correct? Will the gas pumping station also be removed? 

Goal: 

Needed to properly estimate emissions. 

RESPONSE: 

Diesel fuel will be pumped from an onsite diesel fuel pumping station. All gasoline powered 

vehicles will be fueled off site. See response from RAI 8 b below: 

The 6th paragraph of Section 4.6.1, “Air Quality Impacts from Construction,” has been revised to 

address on-site fueling of diesel vehicles. See the following section below as it appears in the 

rewrite to Chapter 4: 

Diesel fuel will be stored on site during construction and will be hand pumped into construction 

vehicles and other plant vehicles involved in construction. Gasoline-powered vehicles (small 

trucks) will be fueled offsite. The fuel tanks will be stored on a containment-type pad, and trucks 

will be driven onto the containment-type pad to start the dispensing process. The pad will be

6. RAI 9 – (Air Emissions during Operations / Gas-Fired Boilers) 

Provide additional information regarding air emissions during the operation of the IIFP facility. 

a. Describe representative capacity (make and models if available) of the gas-fired boilers to be 

 used at the facility and the source of the data used to estimate the boiler emissions.

 

 Discussion: 

The emission estimate for each pollutant listed in Table 4-15 of the March 31, 2011 (final) 

response to RAI 9a is less than the corresponding estimate provided in Table RAI 9-a of the 

February 16, 2011 (draft) response to RAI 9a. While we were able to reproduce the estimates 

provided in Table RAI 9-a of the draft response to RAI 9a, we could not reproduce the revised 

estimates in the final response. No reason was provided to explain the changes to the emission 

estimates in the final response. 

With the exception of NO2, the same emission factors were used in both the draft response and 

the final response. (The emission factor for NO2 was changed from 1E-4 to 1E-5 in the final 

response, which appears to be an error.) Both the draft response and the final response indicate 

that one boiler would operate for 8,760 hr/yr and that emissions are uncontrolled. However, the 

emission estimates in the final response for PM, CO, and NO2 (if an emission factor of 1E-4 is 

used for NO2) are about 20% of the corresponding estimated emissions in the draft response; 

and the emission estimate for SOx is about 25% estimated SOx emissions in the draft response. 

The draft response provided assumptions for fuel heating value (Btu/scf), boiler heat rate 

(MMBtu/hr) which are needed to determine the hourly fuel consumption rate (scf/hr). The final 

response did not include this information. 

Clarification: 

Please provide a complete list of the assumptions used to calculate the Boiler emissions provided 

in Table 4-15 of the final response to RAI 9a. This list should include fuel heating value (Btu/scf), 

boiler heat rate (MMBtu/hr), annual runtime (hr/year), and whether the boiler is assumed to 

operate at full capacity. If the boiler is assumed to operate at less than full capacity please 

describe how that affects the heat rate. If the use of control devices is assumed, please describe 

how the controlled emissions were calculated and include assumptions regarding the control 

devices (e.g., pollutant controlled, device type, control efficiency) 

Goal: 

The assumptions and calculations will provide data to more accurately estimate potential 

emissions. 

RESPONSE: 

There was a typographical error in the NO2 emissions rate from the boilers. 

Further assumptions to calculate the boiler emissions for Table 4-15 are as follows: 

• Fuel heating value – 1,000 BTU/scf natural gas, 

• Boiler heat rate – 11.8 MM BTU/hr (Lower firing rates will only slightly change 

emissions.), 

• Annual runtime – 3,000 lb/hr for Phase 1 operations, 10,000 lb/hr for Phase 2 operations. 

Operating time is 85% of the 8760 hours in the year for Phase 1 and for Phase 2 plant 

operations. 

• Operations boiler efficiency is 85% at full capacity (10,000 lb/hr) and expected to be 1-2 

% lower when the boiler is run at 3,000 lb/hr in the Phase 1 facility operation. 
Response to Talking Points Regarding the Environmental Report (Item 6) Page 14 

The CO and NO2 emissions rates (8.4E-5 lb CO / ft3 NG and 1.0E-4 lb CO / lb NG) are based on 

EPA AP-42, Table 1.4-1, for Uncontrolled Small NG Boilers 

Particulate emissions from NG combustion are all assumed to be PM2.5, therefore, the PM10 and 

PM2.5 emission rates (7.6E-06 lb PM / ft3

 NG) are identical, and are based on EPA AP-42, Table 

1.4-2, for Total PM. No PM emission controls are assumed. 

The SO2 emission rate (6E-07 lb SO2 / ft3

 NG) is based on EPA AP-42, Table 1.4-2. No SO2

emission controls are assumed.

The annual boiler emissions for Phase 2 are approximately three times greater than the boiler 

emissions for Phase 1 (Tables 4-25 and 4-18 in the ER, respectively). The assumptions for both 

Phase 1 and Phase 2 indicate that one boiler with a steam generation rate of 10,000 lb/hr would 

operate for 8,760 hr/yr and that emissions are uncontrolled. 

Clarification: 

Please explain why the Phase 2 boiler emissions are three times greater than the Phase 1 boiler 

emissions and a complete list of the assumptions used to calculate the annual boiler emissions 

provided in Tables 4-18 and 4-25 of the ER. This list should include fuel heating value (Btu/scf), 

boiler heat rate (MMBtu/hr), annual runtime (hr/year), and whether the boiler is assumed to 

operate at full capacity. If the boiler is assumed to operate at less than full capacity please 

describe how that affects the heat rate. If the use of control devices is assumed, please describe 

how the controlled emissions were calculated and include assumptions regarding the control 

devices (e.g., pollutant controlled, device type, control efficiency). 

Goal:

Assumptions and calculations are needed to properly assess emissions presented by the 

applicant. 

RESPONSE: 

The steam requirements for Phase 2 are not known with certainty, but the addition of two more 

autoclaves and a distillation (steam heated) are estimated to add 7,000 lbs. per hour. For 

conservatism, the maximum capacity of the boiler was assumed to be the Phase 2 requirements. 

The boiler natural gas (NG) consumption rate for Phase 2 is assumed to be 11,800 standard cubic 

feet per hour. Also, see footnotes to Tables 4-15 and 4-25 shown above in response to Talking 

Point #6. 

Environmental Report Impact: None.

8. RAI 9 a – - (Same as above) 

 

 Discussion: 

Emission estimates for CO2 and VOCs were omitted from Table 4-15 of the final response to RAI 

9a. No reason was provided for omitting this information and we are unable to calculate this 

number. 

Clarification: 

Please provide the omitted emission estimates and include a complete list of the assumptions used 

to calculate those emissions. 

Goal: 

Assumptions and calculations are needed to properly assess emissions presented by the 

applicant. 

RESPONSE: The values for CO2 and VOCs have been calculated and will be included in Table 

4-15 of the Environmental Report, Revision B. 

Environmental Report Impact: Table 4-15 of the Environmental Report, Revision B will be 

revised as in Item 6 above. 
Response to Talking Points Regarding the Environmental Report (Item 9) Page D-18 

9. RAI 2 – (Phase 1 and Phase 2 Activities & Impacts Separately) 

Revised section 4.1.3.2 indicates no rad waste during either construction phase. Table 3-59 

(167 of 189) lists rad waste generated during both phases. Need to ensure that responses are 

consistent. 

 Discussion: 

Response to RAIs (Table 3-59) shows several types of low-level radioactive waste (LLW) being 

generated during construction; however, we do not see a reason why construction would 

generate LLW, and the applicant stated in earlier discussion with NRC that no LLW would be 

generated during construction. 

Clarification: 

Please clarify the use of the term LLW as applied to construction. 

Goal: 

Need accurate information about waste types to assess impacts. 

RESPONSE: 

It is unclear which section indicates no rad waste generated during both construction phases 

(section 4.1.3.2 nonexistent). During Phase 1 construction, equipment will be shipped from the 

Sequoyah conversion facility below external contamination free release limits. For conservatism, 

LLW was included as potential waste during Phase 1 construction. Section 4.13.2 was revised in 

the Rev B draft provided to the NRC with the RAI submittal which reads as follows: 

4.13.2 Site Preparation and Construction of the IIPF Facility 

Construction of the IIFP Facility will generate solid waste materials that will need to be collected 

and transported off-site for recycling or disposal. It is expected that predominately refuse and 

construction debris typical of industrial construction projects will be generated during the 

construction stage. 

4.13.2.1 Phase 1 Construction 

It is anticipated that less than 3,629 kg (8,000 lb) of radioactive wastes will be generated annually 

during the pre-construction and Phase 1 construction stages. For the construction period for Phase 

1, less than 7,258 kg (16,000 lb) of radioactive wastes will be generated. From Table 3-59, less 

than 817 kg (1,800 lb) of RCRA waste will be generated during the Phase 1 construction period 

and approximately 499 kg (1,100 lb) of other solid wastes will be generated. See Table 3-59, 

“Estimated Annual Quantities of Waste Generated at the IIFP Facility.” The types of waste 

anticipated to be generated will include paper, plastic, cardboard, packaging materials, wood 

scraps, metal building material scraps, roofing and insulation material scraps, masonry and 

ceramic materials, and empty paint and coatings containers. Small quantities of organic solventbased residuals remaining from application of specialty paints, architectural coatings, sealants, 

and adhesives, as well as wastes from certain other materials that possibly could be used for 

construction, may be required to be managed as hazardous waste. The specific compositions and 

quantities for these construction waste types will depend on the final facility design. 

The general design/build contractor selected for the IIFP Facility project will have responsibility 

for the day-to-day supervision of on-site waste collection and storage and for arranging for 

removal of these wastes from the IIFP facility site. Good work practices for facility site waste 

management will be used to collect and sort the wastes for recycling or disposal (e.g., using 
Response to Talking Points Regarding the Environmental Report (Item 9) Page D-19 

designated roll-off containers and collection areas for different types of wastes). Hazardous waste 

generated throughout the construction phase will be temporarily stored on-site and then shipped 

to an off-site facility appropriate for handling the waste composition, in accordance with 

established recycling and hazardous waste management programs. Therefore, the waste 

management impacts attributable to pre-construction and Phase 1 construction of the IIFP Facility 

will be SMALL. 

4.13.2.2 Phase 2 Construction 

It is also anticipated that less than 3,629 kg (8,000 lb) of radioactive wastes, 835 kg (1840 lb) of 

RCRA wastes, and 590 kg (1,300 lb) of other solid wastes will be generated during the 

construction of the add-on buildings for Phase 2. Phase 2 construction necessitates connections to 

existing Phase 1 Facilities and installation of additional autoclaves. It is also anticipated that 

annual quantities of radioactive wastes generated during the construction of the add-on buildings 

for Phase 2 is similar to the rate of generation during Phase 1 construction [less than 3,629 kg 

(8,000 lb) annually]. It is anticipated that the construction cycle for Phase 2 is about one half that 

of pre-construction and Phase 1 construction. Thus, it is also anticipated that the waste 

management impacts from Phase 2 construction will be SMALL. 

Environmental Report Impact: None. 
Appendix D: Non-Radiology Emissions and Impacts Page D-1 

APPENDIX D: NON-RADIOLOGICAL EMISSIONS AND IMPACTS FOR PHASE 1 AND 

PHASE 2 CONSTRUCTION ACTIVITIES 

The International Isotopes Fluorine Products (IIFP) project seeks to construct and operate a facility that 

will (1) convert depleted uranium hexafluoride (DUF6) to uranium oxide and (2) produce marketable 

fluorine chemicals. IIFP must obtain a license from the Nuclear Regulatory Commission (NRC) prior to 

the start of construction. The license application to the NRC includes an Environmental Report (ER). This 

calculation is prepared in support of the ER as part of the license application to the NRC. 

The IIFP Project will be implemented in two separate phases. Phase 1 will include initial site preparation 

activities, road and infrastructure construction, construction of support facilities, and construction of 

several process buildings. Phase 2, which will include the construction of additional process buildings, 

and will be performed after Phase 1 is completed and has already begun operations. Initial site preparation 

activities may be performed prior to the start of Phase 1 construction. These initial site preparation 

activities are designated as "Pre-construction" activities. 

1. Purpose 

The purpose of this report is to quantify the non-radiological emissions attributable to IIFP construction 

activities and to evaluate the impacts for comparison with regulatory standards. 

2. Pollutants Generated By Construction 

Site preparation and construction activities would generate criteria pollutants, hazardous air pollutants 

(HAPs), and volatile organic compounds (VOCs). The criteria pollutants are carbon monoxide (CO), 

nitrogen dioxide (NO2), lead (Pb), ozone (O3), particulate matter less than 10 microns in diameter (PM10), 

particulate matter less than 2.5 microns in diameter (PM2.5), and sulfur dioxide (SO2) (40 CFR 40). HAPs 

are compounds that are believed to cause serious adverse health effects or adverse environmental effects. 

There are 188 pollutants designated as HAPs by the EPA. HAPs are generated by industrial processes and 

fossil fuel combustion. VOCs are organic compounds of carbon that participate in atmospheric 

photochemical reactions (carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or 

carbonates, and ammonium carbonate are excluded). VOCs are primarily generated by solvents, industrial 

processes, and fossil fuel combustion. 

3. Regulations 

The Environmental Protection Agency has established National Ambient Air Quality Standard (NAAQS) 

for criteria pollutants. The NAAQS do not limit release quantities, but instead establish maximum 

allowable pollutant concentrations in the ambient air. Ambient air pollutant concentrations are generally 

measured in units of parts per million (ppm) or micrograms per cubic meter (μg/m3

). Relevant NAAQS 

are illustrated below in Table 4-1 (40 CFR 50). The NAAQS for lead and ozone are omitted because these 

pollutants will not be generated by site preparation or construction activities. 

HAPs are regulated by the EPA under 40 CFR 61, National Emission Standards for Hazardous Air 

Pollutants. Unlike the criteria pollutants, there are no ambient air concentration limits for HAPs. Instead, 

HAPs are regulated through source controls. VOC emission levels are regulated by air permit programs. 

4. Emission Sources 

Pollutants attributable to construction would include (1) tailpipe emissions (also known as combustion 

emissions) from operation of diesel-fired equipment (2) fugitive dust emissions (PM2.5 and PM10) from 

unpaved surfaces generated by wind erosion, soil or powder transfers, and the travel of heavy

construction equipment and (3) fugitive HAP emissions due to evaporative losses from diesel fuel tanks 

and diesel fuel transfers. Separate calculations are applied to estimate these emissions. 

5. Construction Area 

Unlike an emissions stack, which is considered a point emission source, construction emissions will 

originate as an area source. The dimensions of the 40 acre site are roughly 358 meters by 457 meters. 

Area emissions for Phase 1 construction activities are based on 60 percent of the 40 acre area. Area 

emissions for Phase 2 are based on 60 percent of a 1 acre area. 

6. Construction Equipment 

6.1 Equipment Quantities By Month 

Fifteen pieces of equipment are needed during pre-construction. The makeup and quantities of 

that equipment are shown in Table D-2 Thirteen construction vehicles and twelve support 

vehicles were identified for Phase 1 construction. However, four welders have been added to that 

listing making 29 construction/support vehicles. The makeup and quantities of the 

construction/support vehicles used in Phase 1 construction during the first 12 months of 

construction are shown in Table D-3. It is anticipated that the greatest air emissions would be 

generated during the first few months of the first year when the large pieces of earthmoving 

equipment would be used. Fourteen pieces of equipment have been estimated for Phase 2

6.2 Estimated Hours Equipment Operated by Month 

The maximum number of monthly hours of operation for any equipment item in Phase 1 was 

estimated at 160 hours. Table D-5 shows the hours of operation for each equipment item used to 

provide emission data for Tables RAI 8-a-1 through RAI 8-a-12 for Pre-construction and Phase 1 

construction. Additionally, the maximum number of monthly hours of operation for any 

equipment item for Phase 2 was estimated at 160 hours. Table D-6 show the hours of operation 

for each equipment item used to provide emission data for Tables RAI 8-a-13 through RAI 8-a-22

7. Tailpipe Emissions 

EPA Report NR-009d (EPA, 2010) describes pollutant emission factors for calculation of emissions 

attributable to operation of non-road compression engine equipment (i.e., diesel-fired construction 

equipment). Emission factors (grams of pollutant per horsepower-hour) are primarily a function 

equipment horsepower, load factor, and age. Report NR-009d also identifies equipment fuel consumption 

factors in units of "grams of fuel burned per horsepower-hour." Small equipment tends to have larger 

emission factors than large equipment (EPA, 2010). 

To develop the Phase 1 construction emissions calculations, a list of anticipated construction equipment 

(and rated horsepower) was developed. An EPA Standard Classification Code was then identified for 

each equipment item, and an appropriate load factor was selected from EPA-420-P-04-005 (EPA 2004c). 

As described in the User Manual, the EPA NONROAD model was specifically developed to assist states 

and local regulatory agencies across the U.S.A. in the creation of accurate emissions inventories to 

demonstrate compliance with the Clean Air Act. As such, the NONROAD computer model may apply 

some assumptions that are not necessarily representative of the IIFP project. Therefore, to achieve the 

most accurate results, construction emissions were instead calculated based on the data and analytic 

methods published in [1] EPA-420-P-04-009, “Exhaust and Crankcase Emission Factors for Nonroad 

Engine Modeling – Compression Ignition” (EPA 2004b) and [2] “EPA-420-P-04-005, Median Life, 

Annual Activity, and Load Factor Values for Nonroad Engine Emissions Modeling” (EPA 2004c). These 

documents are readily available for public download in PDF format at the websites listed below: 

[1] http://www.epa.gov/oms/models/nonrdmdl/nonrdmdl2004/420p04009.pdf 

[2] http://www.epa.gov/oms/models/nonrdmdl/nonrdmdl2004/420p04005.pdf 

To calculate the peak annual tailpipe emissions for construction, a list of site preparation and construction 

equipment was identified. See Table D-2 for the Pre-construction equipment quantities by month. The 

Phase 1 equipment quantities by month are presented in Table D-3. For the Phase 2 equipment quantities 

by month, see Table D-4. The estimated hours of operation for the Pre-construction and Phase 1 

construction are shown in Table D-5. Table D-6 provide the estimated hours of operation for the Phase 2 

equipment. See Table D-7 and D-8 for the estimated horsepower- hours by month for Preconstruction/Phase 1 construction and Phase 2 construction, respectively. 

Equipment-specific pollutant emission (Spm) rates (in units of grams per horsepower-hour), and the 

Brake Specific Fuel Consumption (BSFC), were then determined based on the analytic methods described 

in EPA-420-P-04-009 (Tier 1 was assumed for all construction equipment). In general, the EPA-420-P04-009 methods (1) postulate a zero-hour steady state emission factor (EFss) for construction equipment 

and (2) present equations to adjust each EFss based on a Transient Adjustment Factor (TAF) and a 

Deterioration Factor (DF). See Table D-9 for the EFss for the construction equipment (Pre-construction, 

Phase 1 and Phase 2 construction). The TAFs are shown in Table D-10. Table D-11 present the BSFCs 

for all the construction equipment. Table D-12 shows the Spm rates for all equipment types. For each 

month of the year, the quantity and average monthly hours of operation for each equipment item was 

estimated. Based on the equipment horsepower, load factor, equipment quantities, hours of operation, and 

pollutant emission factors, the total monthly emissions for each pollutant and each equipment item are 

calculated by Equation 01. 

Tailpipe Emissions, g = (Emissions Factor, g/hp-hr) × (horsepower, hp) × (load 

factor) × (equipment quantity, each) × (hours operated, hrs)

7.1 Pollutant and CO2 Tailpipe Emissions as a Product of Horsepower-hours and Emission 

Factors by Month 

Pre-construction and Phase 1 construction were estimated to last approximately 18 to 24 months. To 

determine the worst-case construction year, months 01 through 03 of this schedule are for Preconstruction, and months 04 through 15 are for Phase 1 construction. The first twelve months of this 

construction period was assumed to the worst-case scenario (maximum annual emissions and impacts) 

since large earthmoving equipment would be used during the initial months. Additional months may be 

necessary for Phase 1 construction, but these months are not included in these responses since the 

calculation of peak annual emissions will occur during the initial months when large earthmoving 

equipment is used. 

Annual construction emissions were then determined as a sum of the monthly emissions for each 

construction interval of interest. Phase 2 construction emissions were developed in a comparable manner. 

A list of planned construction equipment is provided in the tables, along with the applied values for Load 

Factor, EFss, TAF, DF, and BSFC.

7.2 Summary of Emissions 

D-7 provides the Pre-construction/Phase 1 equipment estimated horsepower-hours by month. Table D-40 

(also Table RAI 8-a-3, “Summarize Tailpipe Emissions”) was a compilation of Table D-13 through Table 

D-24. Table D-40 (RAI 8-a-3) has been modified to denote the Months 01 through 03 as Pre-construction 

and Months 04 through 15 as Phase 1 construction. Tables D-25 through D-27 have been added to include 

the last 3 months of the year required to determine peak annual emissions. 

Table D-8 provides the Phase 2 equipment estimated horsepower-hours by month. Table RAI 8-a-14, 

“Pollutant and CO2 Tailpipe Emissions for Phase 2 Construction,” is a compilation of Table D-28 through 

Table D-39. Table D-42 (RAI 8-a-14) was modified to add CO2 emissions. 

The first 12 months of Phase 1 construction was assumed to the worse-case scenario (maximum annual 

emissions and impacts) since the large earthmoving equipment would be used during the initial months. 

Using the first 12 months would result in the peak annual emission and impacts of the various criteria 

pollutants. Table D-40 summarizes the emissions for each month for the first 15 months and has been 

modified to include CO2 emissions. The pollutant and CO2 tailpipe emissions for Pre-construction, Phase 

1 construction, and the worst-case construction year have been summed in Table D-41 to provide the 

worst case scenario for a 12-month period. Table D-42 shows the annual emissions data for Phase 2 

construction (no worst case needed as in pre-construction/Phase 1 construction).

8. Fugitive Dust Emissions 

Fugitive dust is solid particulate matter emitted from any source other than a stack or chimney. Fugitive 

dust particulates occur over a wide range of particulate sizes. The term total suspended particulate (TSP) 

describes the entire range of fugitive particulate emissions (all particle sizes). For initial site preparation 

activities, EPA AP-42, Section 13.2.3.3, cites a TSP emission factor of 1.2 tons/acre/month (EPA 1995). 

After site preparation activities have been completed, it is assumed that fugitive TSP emissions would 

drop to 0.3 tons/acre/month. On average, PM10 and PM2.5 represent 15 percent and 7.5 percent of TSP 

fugitive dust emissions (MRI 2006). For the purpose of evaluation, fugitive dust emissions are assumed to 

occur over 60 percent of the total construction site at any given time. 

Table D-45 (RAI 8-a-5) has been modified to add the 3 additional months of fugitive dusts to the 12 

months in the RAI response. Table D-46 (RAI 8-a-16) was added to present the fugitive dust emissions 

for the twelve months of Phase 2 construction.

9.0 Fugitive HAP Emissions 

Fugitive HAP emissions are generated by evaporative losses from diesel storage tanks and diesel fuel 

transfer operations. The total annual HAP fugitive emissions are calculated as a product of the diesel 

consumption factors from AP-42, and an HAP fugitive emission rate of 0.000028 lb fugitive HAPs per lb 

diesel (SBAP 2010). Table D-49 (also Table RAI 8-a-7 modified) shows the HAP fugitive emissions for 

Pre-construction, Phase 1, and worst-case construction year; and Table D-50 (also Table RAI 8-a-18) 

provides the HAP fugitive emissions for Phase 2 construction. 

Table D- 49 Calculate Fugitive HAP emissions Pre-Construction and Phase 1 Construction

(Also Table RAI 8-a-7) 

778336 lb diesel burned - mass of diesel fuel consumed by construction equipment over the entire year 

0.000028 lb HAP / lb Diesel emission factor for a diesel service station 

Total HAP over one year = 22 lb 

Assumptions 

1. Assumed equipment types are listed in D-2 and D-3. 

2. Construction equipment is operated 10 hours per day, 5 days per week, 50 weeks per year. 

3. All construction equipment is fueled with diesel. 

4. On average, construction equipment consumes diesel fuel at a rate of 0.054 gal/hp-hr (ATTRA, 2007). 

5. Annual storage tank evaporation losses are five percent of tank capacity (ATTRA, 2007). 

6. The temporary onsite fuel storage tank is equipped with enhanced vapor recovery equipment to minimize fugitive VOC emissions.

227499 lb diesel burned - mass of diesel fuel consumed by construction equipment over the entire year.

0.000028 lb HAP / lb Diesel emission factor for a diesel service station.

Total HAP over one year = 6 lb.

Assumptions 

1. Assumed equipment types are listed in Table D-4. 

2. Construction equipment is operated 10 hours per day, 5 days per week, 50 weeks per year. 

3. All construction equipment is fueled with diesel. 

4. On average, construction equipment consumes diesel fuel at a rate of 0.054 gal/hp-hr (ATTRA, 2007). 

5. Annual storage tank evaporation losses are five percent of tank capacity (ATTRA, 2007). 

6. The temporary onsite fuel storage tank is equipped with enhanced vapor recovery equipment to minimize fugitive VOC emissions. 

10.0 Combined Emissions 

Annual pollutant emission totals (tailpipe emissions + fugitive dust emissions + fugitive HAP emissions) 

are summed and reported in the Environmental Report. Table D-51 (Also Table RAI 9-a-9 which was 

modified) presents the combined emissions for Pre-construction, Phase 1 construction, and the worst-case 

construction year. Table D-52 (also Table RAI8-a-19) summarizes the combined emissions for Phase 2 

construction. Annual pollutant emission totals form the basis for calculation of the average emission rate 

for input to SCREEN3. Similarly, monthly maximum criteria pollutant emissions are summed, and the 

maximum sum is selected to calculate time-averaged area emission rates for input to SCREEN3 (this is 

described further in Section 12).

11.0 Site-Specific Meteorology 

Representative regional meteorological data was applied to determine regional air-quality impacts 

attributable to IIFP construction activities. The data, provided by the State of New Mexico, includes 9408 

hourly records that indicate the atmospheric stability and the direction and speed of the wind. Because 

construction activities would occur only in daylight hours, hourly records that occur at night (before 

sunrise or after sunset) were ignored. The stability class / wind speed combinations illustrated in Table 

11-1 represent more than 97 percent of all day time records for the southeastern New Mexico region.

12.0 SCREEN3 

The SCREEN3 computer program is applied to estimate maximum regional criteria pollutant 

concentrations attributable to area source construction emissions (i.e., air quality impacts). Air quality 

impacts are not evaluated for HAPs or VOCs because there are no regulatory metrics for comparison 

(HAP and VOC emissions are regulated by source controls and permit requirements). SCREEN3 

calculates the one-hour average concentration for a range of downwind distances. Key inputs include the 

pollutant emission rate (g/s/m3

), release height (m), receptor height (m), stability class, and wind speed 

(m/s). All construction emissions are conservatively assumed to originate at ground level.

For ground level releases, SCREEN3 results are scalable. Therefore, SCREEN3 is applied to determine 

downwind pollutant concentrations based on a unit release rate of 1 g/s/m2

. SCREEN3 results are 

obtained for each of the stability class and wind speed combinations shown in Table D-53 (RAI 

Attachment Table 11-1). See Tables D-54 and D-55 for Pre-construction and Phase 1 construction. See 

Tables D-61 and D-62 for Phase 2 construction. SCREEN3 results for each receptor location are then 

frequency weighted and the average is selected to represent the concentration.

SCREEN3 is designed to estimate impacts for steady releases. Because construction activities are 

performed only in day time hours and for no more than 160 hours per month, to estimate an average 

release rate for extended time spans, the area emission rates must be adjusted. One-hour, 3-hour, and 8-

hour impacts do not need to be adjusted, because these time spans are smaller than the standard 10 hour 

construction day. The 24-hour impacts, however, must be adjusted to account for intermittent pollutant 

releases. Equations to determine area release rates as input to SCREEN3 are listed below: 

Avg 1-hr Emission Rate, g/s/m2

 = (Monthly Emissions, lb) / (Construction Work Time, 

hrs) 

[EQN_02] 

Avg 3-hr Emission Rate, g/s/m2

 = (Monthly Emissions, lb) / (Construction Work Time, 

hrs) 

[EQN_03] 

Avg 8-hr Emission Rate, g/s/m2

 = (Monthly Emissions, lb) / (Construction Work Time, 

hrs) 

[EQN_04] 

Avg 24-hr Emission Rate, g/s/m2

 = (10 / 24) x (Monthly Emissions, lb) / (Construction 

Work Time, hrs) 

[EQN_05] 

Avg 8,760-hr Emission Rate, g/s/m2

 = (Annual Emissions, lb) / (8,760 hrs) [EQN_06] 

13.0 Impact Calculations 

Frequency-weighted results from SCREEN3 are scaled to determine 1-hour impacts. For example, to 

estimate the impact for a 1-hr concentration, SCREEN3 results are scaled based on the average 1-hr 

emission rates as determined by EQN_02. Similarly, to estimate the impacts based on 3-hr, 8-hr, 24-hr, 

and 8,760-hr average area release rates, SCREEN3 results are scaled based on the average emission rates 

as determined by EQN_03, EQN_04, EQN_05, EQN_06, respectively. It is important to remember that 

SCREEN3 will estimate only the 1-hr average concentration – it does not reveal the average 

concentration for other time spans, such as 3-hr, 8-hr, 24-hr, and 8,760-hr. However, EPA has identified a 

set of scale factors that may be applied to estimate the 3-hr, 8-hr, 24-hr, and 8760-hr average 

concentrations based on the 1-hr average concentration. Table D-68 (also RAI Attachment Table 13-1) 
Appendix D: Non-Radiology Emissions and Impacts Page D-70 

illustrates these scale factors. Additionally, an example is provided below to illustrate this process. 

Emissions and impacts are determined separately for Construction Phase 1 and Construction Phase 2. 

Example: Assume the maximum monthly SO2 emissions are 62 pounds; the annual SO2 emissions 

are 511 pounds; construction occurs 208 hours per month; and the dimensions of the area with active 

construction at any given time are 274 meters by 354 meters (96,996 square meters). Further assume 

that based on the site-specific meteorology and a unit area release rate (1 g/s/m2), the frequencyweighted SCREEN3 result at 200 meters is 8.28E+05 μg/m3

. There are four NAAQS for SO2 (1-hr, 3-

hr, 8-hr, and 8,760-hr). Calculations are illustrated below to determine the project impact for 

comparison with each SO2 NAAQS. 

1-hr impact

As shown in Table 13-1, for a 1-hr impact, the SCREEN3 scale factor is 1. 

Release Rate = { (62 lb) / (208 hr) / (96996 m2

) } × (453.59 g/lb) / (3600 s/hr) = 3.87E-7 g/s/m2

1-hr average impact at 200 meters = (SF) × (SCREEN3 1-hr concentration) × (SO2 1-hr Release Rate) / 

(Unit Release Rate) 

1-hr average impact at 200 meters = (1) × (8.28E+05 μg/m3

) x (3.87E-7 g/s/m2) / (1 g/s/m2) = 0.32 μg/m3 

3-hr impact

As shown in Table 13-1, for a 1-hr impact, the SCREEN3 scale factor is 0.9. The average release rate 

over a three hour span is the same as the release rate for a one hour span. 

Release Rate = { (62 lb) / (208 hr) / (96996 m2

) } × (453.59 g/lb) / (3600 s/hr) = 3.87E-7 g/s/m2

3-hr average impact at 200 meters = (SF) × (SCREEN3 1-hr concentration) × (SO2 3-hr Release Rate) / 

(Unit Release Rate) 

3-hr average impact at 200 meters = (0.9) × (8.28E+05 μg/m3

) x (3.87E-7 g/s/m2) / (1 g/s/m2) = 0.29 

μg/m3 

8-hr impact

As shown in Table 13-1, for a 1-hr impact, the SCREEN3 scale factor is 0.7. The average release rate 

over an 8-hour span is the same as the release rate for a one hour span. 

8-hr Release Rate = { (62 lb) / (208 hr) / (96,996 m2

) } × (453.59 g/lb) / (3600 s/hr) = 3.87E-7 g/s/m2

8-hr average impact at 200 meters = (SF) × (SCREEN3 1-hr concentration) × (SO2 8-hr Release Rate) / 

(Unit Release Rate) 

8-hr average impact at 200 meters = (0.7) × (8.28E+05 μg/m3

) x (3.87E-7 g/s/m2) / (1 g/s/m2) = 0.22 

μg/m3 

8,760-hr impact

As shown in Table D-72, for a 1-hr impact, the SCREEN3 scale factor is 0.08. The average release rate 

over an 8,760 hour span is determined based on annual release total and 8,760 hours. 

Release Rate = { (511 lb) / (8760 hr) / (96996 m2

) } × (453.59 g/lb) / (3600 s/hr) = 7.57E-08 g/s/m2
Appendix D: Non-Radiology Emissions and Impacts Page D-71 

8,760-hr average impact at 200 meters = (SF) × (SCREEN3 1-hr concentration) × (SO2 Annual Release 

Rate ) / (Unit Release Rate) 

8,760-hr average impact at 200 meters = (0.08) × (8.28E+05 μg/m3

) x (7.57E-08 g/s/m2) / (1 g/s/m2) = 

0.005 μg/m3

Assumptions: 

1. Pollutant impacts are determined based on the peak emissions generated by site preparation. 

2. The peak one-hour concentrations are as determined by SCREEN3. 

3. To determine the peak 3-hour concentration, the peak one-hour concentration is scaled by 0.9 based on EPA guidance 

on EPA guidance. 

4. To determine the peak 8-hour concentration, the peak one-hour concentration is scaled by 0.7 based on EPA guidance. 

5. To determine the peak 24-hour concentration, the peak one-hour concentration is scaled by 0.4 based on EPA guidance 

and by 10/24 to account for limited work day. 

6. To determine the peak annual concentration, the peak one-hour concentration is scaled by 0.07 based on EPA guidance, 

by 10/24 to account for limited work day, then adjusted to account for 4 months of peak emissions (site preparation), 

7.5 months of reduced emissions (post site preparation), and two weeks of zero emissions. 

7. Scale Factors to estimate impact concentrations other than one hour based on Average 1-hr as 1.00, 3-hr as 0.9, 8-hr as 

0.7, 24-hr as 0.4, and annual as 0.08.
