International Paper performed an inventory of their sources and realized that while performing demolition work at their facility, two unused process
gauges were removed from the site. The removal of the
gauges was outside the scope of the demolition work. The two process
gauges were located on long poles, were removed from the site using a crane, and were sent to a nearby scrap yard. The
South Carolina Division of Health and Environmental Control sent an inspector to the scrap yard and he was able to find and recover both
gauges. The shutter on one
gauge had remained closed and the second
gauge shutter was partially open and reading 50 mR/hour on contact. The first
gauge was recovered at 1220 EST and the second
gauge was recovered at 1315 EST and the shutter was shut. Wipe tests on both
gauges were negative. The
gauges were returned to International Paper and are locked in a secure location. No personnel exposures were expected from this incident.
