171Welding and Storage pile 2 are modeled as a volume source using the shorter side and height for calculating initial lateral diemension and vertical dimension.
18=1+A17Release height for welding is taken as half of the building height.
19=1+A18Release height for storage piles is taken as half of the average storage pile height. Screenshots below show the heights taken from google Earth.
20=1+A19Release height for woodchipper based on height of woodchipper
21=1+A20Initial lateral dimension is calculated by dividing the shorter side of the building/pile by 2.15 or 4.3 per Table 3-3 of EPA AERMOD User Guidance.
22=1+A21Initial vertical dimension for welding is calculated for elevated sources in a building and for storage piles, it is calculated for elevated sources not adjacent to a building.
23=1+A22Elevation for fugitive sources in buildings will be the same elevation as the buildings
