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
