Gilsenan, Michael From: Nudelman, Harold Sent: Monday, October 15, 2001 5:43 PM To: Gilsenan, Michael Cc: Kelpin, Gerry 001 Subject: 10/15 3 PM conference call
The call was relatively short. 1) A call earlier this AM by EPA, et al had discussed some issiues like the data and indoor and outdoor sampling plans. Given this call Jessica from CDOH suggested that we only have our calls tuesday and friday. Everyone agreed -thisis to start next week. This week it seems we will have a call only Friday and drop Wednesday. I will verify tomorrow. 2) Indoor plan to go out COB today-conference call on this maybe thursday AM. Not clear why we have Tuesday ay 11 conference call? 3) OEM had indicated plans to open up sidestreets between Broadway and Church- and bldgs with entrances on B'way. CDOH has walked through the area. One high buld asbestos sample was identified at 5 WTC-this will be watched. Personnel monitoring of asbestos reported low recently. 4) EPA reported higher dioxins at 4 sites , with the SW side of WTC5 ,in the plaza , having the highest average. This was a 10/2 sample of ~ 8 hours. EPA will have 10/4 samples soon. OEM to be informed as well as FD by CDOH and others. The levels were not a short term problem as they estimated you would need 100 days at the level measured at Curch and Dey to reach the background level. There is now more of a concern for the dioxin than before, as EPA didn't think we would be dealing with dioxin for this long as they thought the fires would be out .Turnaround time for dioxin analysis is about 7-10 days. Tommorrow night there will be a community meeting on PCBs and dioxin and young children. 5) Some high benzene levels were again found . These must also be communicated to OEM9health) 6) Some higher asbestoos levels at AK -no exceedance of AHERA , but close-larger fibers prdomonate. 7) OSHA issue on CO was raised- IDLH approached with peaks of -800, the IDLH is -1200.
