Part IV- Waste Management Plan
133-135 Greenwich Street/21-23 Thames Street
Airtek Project 05-0701— Rev 1, September 16, 2005
Results of the sample have been compared to criteria provided in 40 CFR Part 261
sections 21 through 24 and Environmental Protection Agency Publication SW 846
Chapter 7. The sample does not exceed the criteria provided in 40 CFR Part 261
sections 21 through 23 or SW 846 Chapter 7.
Given the limited nature of the sampling, no broad conclusions on waste
characterization can be drawn from these results.
4.0 Waste Characterization Strategy
Waste generated during the project will be characterized, managed, transported
and disposed of in compliance with this Waste Management Plan and applicable
regulations.
4.1 Contaminants
Full-building asbestos surveys have been conducted. In-place ACBM has
been identified, located and included in the Project Plan. No further
characterization will be conducted unless site conditions reveal additional
suspect materials not addressed in the ACBM surveys.
WTC Dust is assumed to exist at the site.
4.2 Deconstruction Waste
Dust sampling for hazardous waste characteristics has been performed in
advance of sampling of materials impacted by dust. It is anticipated that
the dust classification sampling will indicate that the dust is not a
characteristic hazardous waste, and then by extension, any non-hazardous
materials potentially impacted by dust (i.e., the Deconstruction Waste
listed in subsection 2.2 above) would also not be hazardous. Due to the
limited nature of the preliminary sampling, confirmatory sampling of the
various deconstruction waste categories will be conducted to confirm this
prior to commencement of any site work.
Those materials would then not be sampled for Resource Conservation
and Recovery Act (RCRA) characteristics unless there is an independent
concern that they might be hazardous waste due to the inherent
composition of the component, subcomponent or waste stream (e.g., light
ballasts which may contain PCBs, items coated with lead-based paint).
Porous deconstruction waste will be disposed of according to the results of
waste characterization sampling, and as ACM at a minimum.
Non-Porous Deconstruction Waste may be managed by either of two
options. The Abatement Subcontractor may choose to clean the non-
porous surfaces in accordance with procedures outlined in the Work Plan.
