NYC 9/11 Public Portal Document

-v • - Sent: Tuesday, April 16, 2002 7:32 AM To: Radhakrishnan, Krish Subject: American Express Building On April 15, 2002 I met with Chris Sexton of Total Safety Consulting (212) 640-9136 and Michael Handler of Turner Construction 212.786.1480. The purpose of the meeting was to discuss the planned washdown of 1, 2, 3, 4 World Financial Centers. At this time, all the decontamination of the exterior had been completed. Samples had been collected for ACM and were negative.

Their concern was that when the washdown starts they do not violate any of DEP regulations. Water would be trucked in from outside so as to observe water restrictions. This they felt was the right thing to do, even if DEP allowed them to used the pipe borne supply. The washdown is a plain washing to give the entire clean up some finality. It was agreed that some soil sampling would be done where the run off is expected. So as to ensure that no form of contamination get into the sewer system. A review of the ACM sampling done revealed that only 4 samples were collected from each building (total of 16). Most had trace ACM. I requested that more sampling be done as 4 samples are not sufficient to represent the enormity of the buildings. However, they said that samples may be hard to find. In the end it was agreed that more samples would be taken. If the additional samples are negative, then the cleanup can go on as planned. A look at some of the small window ledges revealed that they were free of debris.
