11. This section seems to imply that there is only dust to be found in the kitchen. Dust may also be potentially found in the interstitial spaces, and dust has been seen on windows, window sills, mattresses, the floor, etc. Additionally, since there is a large amount of debris currently covering the floors, in particular at 21-23 Thames Street, it is unknown how much dust may be within that debris and the floor beneath that debris. This section should be re-written to note that fact.

The section has been editedfor clarity.

Section 3.3, Page 6:

12. It is not appropriate to make preliminary conclusions for the buildings being demolished as part of this project based on sampling results taken at 130 Liberty Street and 4 Albany Street for the reasons explained above. Further, it is not appropriate to make assumptions about all of the building components in both buildings based on one analytical sampling result taken from one room of one floor of the buildings. This section should be re-written to address these concerns.

Section 3.3 has been removed.

Section 3.3 has been removed. Section 2.3 has been edited as noted.

14. Need to add "at a minimum" to the end of the first sentence.

Section 3.3 has been removed.

15. The last sentence should be re-written to state the following: "Waste generated during the project will be characterized, handled, transported and disposed according to applicable regulations and waste characterization conducted by the Environmental Consultant."

Section 3.3 has been removed.
