DRAFT EXCERPTS FROM SECTION 4: FOR REVIEW & DISCUSSION PURPOSES ONLY

Asbestos Work Practices Used in the WTC Complex Demolition

The New York State Department of Environmental Conservation is delegated responsibility for implementing all Federal regulations under the NESHAP program. NYCDEP is responsible for the asbestos abatement program in New York City. Even though authority to run the program in New York was delegated to the State and local agencies, EPA retains the authority to oversee agency performance and to enforce NESHAP regulations as appropriate.

The NESHAP emergency requirement - - wetting damaged buildings before demolition and continuous wetting of the debris after demolition - - appeared to have been followed.

Instead, daily meetings were held to plan the day’s activities and address any special work practices that may be required to reduce possible emissions of asbestos.

Written NESHAP Notifications Not Prepared

EPA and New York State asbestos NESHAP regulations require that a notification be filed even in emergency situations. The notification process provides an opportunity for government officials to discuss and determine the preferred work practices to be used in demolition and renovation operations. Notification of a NESHAP demolition and removal operation was not filed for the WTC. City officials stated that a written notification was not filed for WTC buildings 4, 5, and 6 because they were advised by the property owners that there was no asbestos-containing material in the above ground structures. NYCDDC officials told us that they were advised by the Port Authority that subsequent to
