Subject: FW: 3811-07 Revised Felman Fugitive Release Height

Chuck --

As we discussed a while ago, attached is a table outlining the fugitive release heights from all of the openings identified in the Felman

drawings. l’o account ft)r the relative size of each opening, LAN calculated the total area of all openings, then determined eachopening’s percent contribution to the fligitive release height by dividing each opening’s area by the total area of’ all openings. The

fugitive release height for the building was then determined by summing the product of the height of each opening and its percent

contribution. LAN perftwmed this analysis separately for each side of the building to develop effective opening heights for the NE,NW, SW, and SE sides of the building. The overall average fugitive release height was 12.33 meters.

Please let me know if you have any questions or need additional information. Thanks, and have a happy Thanksgiving.
