SUBJECT: PROPOSED FUNDING FOR PCB LANDFILL
DETOXIFICATION
I have attached the estimated cost page from the draft Phase II detoxification
report based on additions and corrections made during the last couple of weeks in
mee~ngs with the contractor, science advisor's and division personnel. We
anticipate a total cost of around 24 million, which includes a 10% contingency.
The final Phase II report is to be delivered on April 4.
I have also attached a copy of the "Explanation of Selection of Two
Deto~ification Technologies" summary that was a part of the Request for
Proposals sent out last year on the detoxification efforts. The two technologies
sclec~ed for testing included the Base Catalyzed Dechlorination (BCD, company
ETO:Environmental) and Chemical Oas Dechlorination (Ecologic Process,
company ECOLOGIC). The BCD process was chosen following the Phase I
bonch scale testing procedures as the technology to pursue for detoxification.
It should be noted that the process all along has looked at the best technology for
this t}'pe of contaminated soil and the best long term solution for the PCB
Lan<ipll, and has not been cost driven. The process has followed very closely the
same procedures that EPA uses to evaluate the cleanup of Superfund National
Prio~ty Listed sites (NPL). · .
Pie~ call me should you have any further questions.
