ir t&faces thoughout the indoor areas of the 9th, 10th, and 11th floors were generally ` tdt residual loose dust; However, many surfaces contained an engrained residue that we detected by wiping with white paper towels.

These surfaces should be HEPA vacuumed as Wet wiped with appropr late surfactants and disposable paper towels.

;:~►; erD-vac' vaouhm samples were taken from five representative sites to examine in #h1y *oratory for residual asbestos fiber (TEM method), fiberglass fiber (SEM I ,. mo) and other particl es -(PLM method), The enclosed EMSL laboratory teaitte indicate that at these' five sites no detectable levels of asbestos were present, 4nI Twat only trace levels of fiberglass and other particulates were=present.
