Sampling results following the second cleaning indicated levels below the primary clearance criterion.

Post Cleaning Samples - Three air samples and five wipe samples were collected after the first cleaning. The results for the three air samples indicate that MMVF was present; however, both samples were below the primary clearance criterion of 10 SZL. The results of the five wipe samples indicate that MMVF was still present after the first cleaning; however, the concentrations detected were generally lower than the pre-cleaning samples. There is not a clearance criterion for MMVF in settled dust.
PAH Before Cleaning Samples - Four pre-cleaning wipe samples were collected. AU four samples were below the detection limit and the TEF for each sample was below the primary clearance criterion.
