Calculation of Emission factor for Material Handling at Stockpile in East Portion

According to Section 13.2.4 of AP-42

where

E = Emission Factor in kg/megagram (Ref. AP42 S13.2.4)

k = Particle size multiplier, k = 0.74 as defined according to Table 2 of S13.2.4

U = Average wind speed from 2006 to 2010 (i.e. ~3.357m/s)

M =

E = 0.74 x (0.0016) x (3.357/2.2)^1.3/(2.0/2)^1.4

= 0.00205 kg/megagram

Maximum No. of trucks loading/unloading at stockpile = 16.7 per hour

Average carrying capacity for each truck = 11 tonne

Quantity of excavated materials loading at Stockpile = 184 megagram per hour

Mitigation efficiency (%) = 50.00% watering once per hour

Emission Rate = 0.00205 x 183.7 x (1 - 0.5)

= 0.18837 kg/hour

= 0.05233 g/s


For Stockpile Area (Source ID E-SP02)

Emission Rate = 0.05233 g/s

Total Area for Stockpile = 5225 sq. m

Emission Rate per unit area = 0.000010015 g/sq.m/s

Unmitigated (Working Hours)

For Stockpile Area (Source ID E-SP02)

Emission Rate = 0.10465 g/s

Total Area for Stockpile = 5225 sq. m

Emission Rate per unit area = 0.000020029 g/sq.m/s

Material moisture content - Based on the GI sampling results, the moisture content of the soil samples at different depth (approx.

0.5m to 20m below ground) in the study area is in the range of 6-30% (see details in "Moisture Content of Soil Samples in Study

Area") . Considering the ambient relative humidity and the effect of evaporation when exposed to air, 2.0% is assumed in the

equation for conservative assessment.

Calculation of Emission factor for Material Handling at Barging Point

According to Section 13.2.4 of AP-42

where

E = Emission Factor in kg/megagram (Ref. AP42 S13.2.4)

k = Particle size multiplier, k = 0.74 as defined according to Table 2 of S13.2.4

= 0.00205 kg/megagram

No. of trucks loading/unloading at each barging point = 10 per hour

Average carrying capacity for each truck = 11 tonne

Quantity of excavated materials loading at Stockpile = 110 megagram per hour

Mitigation efficiency (%) = 50.00%


Emission Rate = 0.00205 x 110 x (1 - 0.5)

= 0.11280 kg/hour

= 0.03133 g/s

Unmitigated (Working Hours)
