NYC 9/11 Public Portal Document
most stringent assessment and evaluation, this material is assumed to be ACM and shall be cleaned by NYS DOL licensed contractors with DEP and NYSDOL certified workers." This contradicts the DEP approach to assessing and mitigating WTC dust since 9-11. DEP should indicate that results of its bulk sampling data indicates that the debris generated by the collapse of the WTC towers is not a homogenous material. Results of air sampling by DEP and others indicates that WTC debris does not tend to aerosolize and is not a significant source of airborne asbestos fibers, in addition, field observations indicate the WTC debris is non-firiable and represents a low hazard potential.
DEP should state its approach to assessing and mitigating WTC dust since 9-11.
