inspected for debris from any sources, residue, dust or other matter. If any such debris is found,

the CONTRACTOR shall repeat cleaning and continue decontamination procedures.




B. The ENVIRONMENTAL REPRESENTATIVE shall then inspect the asbestos regulated area

after the area has been cleaned to the satisfaction of the CONTRACTOR’S Superintendent. If any

debris is found, the CONTRACTOR shall repeat cleaning and continue decontamination

a laboratory so that verbal reports on samples can be obtained within 24 hours of receipt by the

laboratory or will be read on site by a NIOSH 7400 trained individual.

B. If analysis by PCM indicates that the concentration of fibers in any of these samples exceeds the

Release Criteria of 0.01 f/cc, the CONTRACTOR shall continue to clean the work area until air

monitoring has indicated that fiber concentrations have fallen below this limit.
