Haul Truck Emissions
Emissions from hauling construction <strong>and</strong> demolition debris are estimated in this spreadsheet.
Emission Estimation Method References: United States Air Force (USAF) Institute <strong>for</strong> Environment, Safety <strong>and</strong>
Occupational Health Risk Analysis (IERA) Air Emissions Inventory Guidance Document <strong>for</strong> Mobile Sources at Air Force
Installations (Revised December 2003).
US EPA Estimating 2003 Building-Related Construction <strong>and</strong> Demolition Materials Amounts (March 2009).
Assumptions:
Haul trucks carry 20 cubic yards of material per trip.
The average distance from the project site to the base l<strong>and</strong>fill is 10 miles, <strong>and</strong> from the project site to the offsite Cerro Colorado L<strong>and</strong>fill is 30 miles.
Assume 85% of demolition waste would go to the base l<strong>and</strong>fill <strong>and</strong> 15% would be transported offsite. There<strong>for</strong>e a haul truck will have a weighted
average of 26 miles round trip.
Estimated number of trips required by haul trucks = total amount of material demolished on installation/20 cubic yards per truck
Typical non-residential demolition materials generation per unit area: 158 lb/ft 2 EPA 2009
Total demolition waste removed: 253,352 ft 2 From Project Combustion
Total demolition waste: 40,029,616 lbs Density of demolition waste * project area
Density of demolition waste: 150 lbs/ft 3 Density of concrete (EPA 2009)
Total volume of demolition waste: 9,884 cubic yards
Number of trucks required to haul demolition waste: 494 Heavy duty diesel haul trucks (20 CY)
Miles per round trip: 26 miles Weighted average
Heavy Duty Diesel Vehicle (HDDV) Average Emission Factors (grams/mile)
NO x VOC CO SO 2 PM 10 PM 2.5 CO 2
HDDV 6.500 4.7000 19.10 0.512 7.7 2.01 1646
Notes:
Emission factors <strong>for</strong> all pollutants except CO 2 are from USAF IERA 2003.
Emission factors <strong>for</strong> PM, PM 10 , SO x are from HDDV in Table 4-50 (USAF IERA 2003).
Emission factors <strong>for</strong> VOC, CO, <strong>and</strong> NO x are from Tables 4-41 through 4-43 <strong>for</strong> the 2010 calendar year, 2000 model year (USAF IERA 2003).
Diesel fuel produces 22.384 pounds of CO 2 per gallon.
It is assumed that the average HDDV has a fuel economy of 6.17 miles per gallon, Table 4-51 (USAF IERA 2003)
CO 2 emission factor = 22.384 lbs CO 2 /gallon diesel * gallon diesel/6.17 miles * 453.6 g/lb

Example Calculation: NO x emissions (lbs) = 26 miles per round trip * 494 trips * NO x emission factor (g/mile) * lb/453.6 g
