DATE: PROJECT: DATE OF SAMPLES: SUMMARY:
RECOMMENDATIONS:
June 3, 1983.
Measure asbestos concentration in the vicinity of a roped-off area, where insulation was to be
removed, west of 11 boiler; Enerj^y_Systems.
3-15-83, 3-17-83
The long term monitoring of the roped-off area west of #1 boiler showed average asbestos fiber counts of less than 0.1 fibers/cc. This level is well below the permissible exposure limit of 2 fibers, longer than 5 micrometers, per cubic centimeter of air.
