should (sic) results were in excess of J % Chrysotile asbestos, the results rangedfrom 1.30% to 30.80%. The three samples that were not above J% were detectfor Chrysotile asbestos. These samples were taken from wind braces and girders that were suspected to contain asbestos. The samples were split samples with Bovis’s asbestos abatement contractor. Restdts of the contractor samples are not yet available.

The situation reports also noted the presences of asbestos-containing material and the operation of another abatement project in April 2002. According to the April 5, 2002, Situation Report, bulk testing showed that one sample of the pipe wrap that was being removed as part of this abatement contained 66 percent amosite asbestos.

Removal of Debris From Site

In an effort to minimize potential exposure to dust from the transportation of WTC to the Fresh Kills Landfill, City. State and Federal agencies established procedures for vehicles transporting this debris. These procedures required among other measures that tarps be placed over the vehicles and that the vehicles be wet down at a wet down station. The wet down station was operated by contractors of the EPA. The volume of truck traffic during the peak period was very large, thus presenting a challenge to insure that the procedures worked properly. In addition, the weather conditions, particularly in the winter and the high temperature of some of the debris also presented challenges to overcome in insuring the process worked properly. Particularly in the weeks immediately following the disaster, trucks hauling debris from the site did not consistently stop to be wetted down before leaving the site. This problem was recognized by the City and the City instituted measures to enhance compliance. City agencies, around October 12. 2001. began issuing summonses for failure to secure loads or to stop to be wet down. As many as 300 summonses were issued by the City. The City also enlisted the assistance of the New York State Department of Environmental Conservation Police, assisted by the National Guard, to enforce the requirement to stop at the wet down stations. As a result, assistance was obtained from the New York Police Department to-ensure that trucks stopped-at-the wash-stations befor-e leaving the-site; Even after this. truck.swithextremelyhotdcbris gettingPoliceDepartraentassistaneeto-ensure that-true-k-s-stopped-at-the-washing station;-EPA Situation Reports-indiceted that the-trucks-weredid not stopping long enough to get completely wetted down. EPA Situation Reports indicated that as late as October 13, 2001, this was still a problem. However, by the end of October 2001 to the beginning of November 2001. the problem was solved and almost 100% of the trucks were stopping at the wet down stations for a proper wet down. This success can be attributed to the cooperation of the City. State and Federal agencies and to the capability of the EPA contractor in dealing with various technical problems.
