NYC 9/11 Public Portal Document Greenwich to Bdway between chambers and Murray

Cleanup work was completed on 9 26/01 at OSOOhours in the a .a from Greenwich to Broadway, between Chambers and Murray. Advised that Construction COHipany iS responsible to insure no emissions from vehicles occur. At minimum, all loads must be substantially wet down, covered undi tarps, and vehicles washed. Air monitoring was conducted in this area to maintain clearance levels. Four air samples were taken in die proposed area each day. All four samples passed clearance level. These results were as follows:

DOH Received draft vehicle advisory as promised from DOH. Made comments and returned.

First Response

First Response peisoimel Fawzy and Haas made entry with FDNY and ESU into a new un chartered area in the southwest corridor below the trade center. DEF provided real time monitoring for vital support gases in the environment and took air and water samples for further analysis. Investigation of the stability of the slurry wall was performed by engineers. Dep took samples of water intrusion to determine if it is possibly from the river. Additionally, air and water samples were taken to check for R22 refrigeraftt. Ab attempt was made by rafts to try to get through a flooded area to the fr^n tanks to assess there condition but was unsucc-essfiil because of debri in the pathway.

The daily ground zero monitoring for dangerous gases showed normal background levels.

Future Progress

DERTA has surveyed other areas inside die perimeter in an effort to target potential sites to be opened. DERTA does not believe that it will be possible to clear any other areas because of the close proximity to ground zero. Major work at ground zero would have to be completed before we could reassess the feasibility of opening another area.
