NYC will work with building owners to determine reasons that these buildings have not been cleaned yet. If building owners are not able to expeditiously clean their property, NYC will proceed.

Status ofRequestfor FEMA mission assignment: Andy Alper’s letter was good on the economics. However, because this is indoor, you need a connection which addresses the inside. Need to show exterior impact/economic impact. Is there a risk or nuisance. Took an e-mail last time from Jane Kenny. (Exterior building cleanup) Must identify the vehicle for enforcement for them. Debris removal to be eligible under their regs, it must be necessary “to eliminate immediate threat to Uves, public health, and safety.”
