The flow rate is 12500 SCFM - (i.e. 11000 from the stack fan and 1500 from the scrubber fan) Steven H Swearingen I f Steven H Swearingen 02/20/2002 09:43 AM To: Debbie J Mulrooney/AE/DuPont@DuPont cc: Robert F Pinchot/DEV/AE/DuPont@ DuPont. Todd M Krieger/AE/DuPont@DuPont Subject: Environmental Impact Study Several months ago for Rob Pinchot you did a screening study of ground level exposures for APFO. Since that time as a normal course of the project, stack heights and gas flow rates have changed. Todd Can you provide Debbie with updated flow and stack height? Debbie: Can you take revised figures and append and re-issue your study. thanks. EDD0068694
