Drake Cleanup Suspends Feed; Runs Monthly Calibration Checks
LOCK HAVEN, PA; March 23, 1998 -- Contaminated soil feed to the Drake Superfund incinerator was suspended at about 10 a.m., today, and will remain off for about eight to 12 hours while technicians perform normal monthly interlock tests.
Feed to the incinerator was off due to normal maintenance on the feed screws, while at the same time, daily calibration was being performed on the stack's continuous emission monitoring (CEM) system. In the process of CEM calibration, a valve on the active monitoring system was inadvertently shut off. This produced a false CEM reading which prevented the system from restarting.
With the system feed shut off, EPA agreed to allow the contractor to go ahead and perform the monthly battery of calibration and interlock checks which had been scheduled for later in the week. The system has been purged of all contaminated soil for testing. This panel of tests includes an opening of the TRV to insure that it will function properly if needed.
