MEMORANDUM
SUBJECT: Effect of Water—Stripped POliCs on
Incinerator DRE
FROM: John U. Skinner
Director
Office of Solid Waste (WH —562)
TO: Roland W. Schrecongost
Acting Director
Hazardous Waste Management Division, Region III
(3 HWO 0)
In your memorandum of June 11 (attached) you requested
Headquarters’ guidance regarding the calculat .on of Destruction
and Removal Efficiency (DRE) for a RCRA incine:’ator using plant
process water in its scrubbers. As was discussed in the Inciner-
ator Workgroup conference call held on June ib, we agree with
your opinion that: (1) toluene and acrylonitrile, found in the
process water, are suitable POHCs for Union Carbide’s unit; and
(2) all POHCs in the exhaust gases, including any PCHCs strtpped
from the scrubber, should be included in the DRE calculation.
Please contact Pablo Vaquer of my staff on rS_382_L 5 5 if you
have further questions regarding tnis issue.
