required. Empty extinguisher bodies shall be rendered inoperable by cutting in half or
puncturing, then recycling as scrap metal or disposing as municipal solid waste."
Language added.
Section 6.4. Paae 14:
46. Discuss representability of proposed sampling number. See comment numbers 26
and 27 above. Further, please clarify if Airtek is proposing one composite sample per
structural and facade material that will consists of five grab samples.
One sample per material, per building at a minimum prior to the demolition
phase. Environmental Consultant may determine more sampling is appropriate.
Section revised.
Section 7.0, Paae 14:
47. This section discusses what Airtek plans to do with non-porous deconstruction waste.
The Waste Sampling and Management Plan does not discuss the approach to be taken for
porous deconstruction waste. Include a section that discusses the handling, management,
storage, disposal, and transport of this waste stream.
The entire Waste Sampling and Management plan discusses porous
deconstruction waste, which is nearly all of the waste, and which is being handled
under negative pressure containment during the abatement phase. Section 4
discusses waste characterization, section 5 discusses analytical methodologies,
and section 6 discusses sample frequency. Non porous waste has been broken out
into a separate section due to the possibility of its being cleaned and
disposed/recycled. No such possibility existsfor porous wastes.
48. Add "(i.e., not recycled)" at the end of the first sentence of the first paragraph.
Added as noted.
49. This section indicates that painted non-porous deconstruction will be sampled and
analyzed for TCLP lead, cadmium, and chromium. Since painted surfaces may contain
other metal components such as arsenic and mercury, and Airtek will be running a TCLP
analysis, Airtek needs to include all of the metals in its TCLP analysis to determine if the
painted surfaces would cause the material to be classified as a hazardous waste. Revise
this section to state that sampled will be analyzed for, and compared to, the TCLP metals.
Edited to include RCRA Metals.
50. Airtek states that if "results of the settled dust classification sampling indicate that
the dust results exceed the regulatory threshold for one or more RCRA characteristics, the
waste will be managed as both a RCRA waste of the appropriate waste code as well as
