• Environmental sampling in the neighboring 130 Liberty Street Building has verified the presence of these chemical contaminants in WTC dust in concentrations exceeding USEPA's Residential Cleanup Criteria.

Additional chemical hazards generated from deconstruction activities would be lead, cadmium, and chromium from coated surfaces. Subcontractors shall perform personnel monitoring for all COPCs as required by OSHA. In addition, Subcontractors must provide applicable OSHA training for the identified hazards. Documentation of this training must be provided by the Subcontractor.

Additional precautions to be taken in work areas because of the presence or potential presence of WTC dust include personnel and area air monitoring. Any torching or cutting of painting surfaces creates risk of lead, cadmium and chromium release. During these operations, additional monitoring and PPE will be necessary as required by the Lead in Construction Standard [29 CFR 1926.62(d)(2)(iv)] and the Cadmium in Construction Standard [29 CFR 1926.112].

Precautions to be taken during the removal of miscellaneous hazardous materials (bulbs, ballasts, batteries, mercury-containing thermostats, etc) are found in Table 2-1, Task 3. Respiratory protection, as identified within Table 2-1, represents the minimum level of protection for all identified tasks.

There may also be hazardous chemicals brought on-site and used in the deconstruction. • The requirements of the OSHA Hazard Communications Standard (29 CFR 1910.1200) shall apply. Section 2.8 provides information concerning the management of hazardous chemicals on-site and the site Hazard Communication Program.
