Dear Stewart:
RA
DEHNR
As you are aware, the State of North Carolina is committed to evaluating BCD as a technology
to detoxify the Warren County PCB Landfill. We appreciate your assistance in this important
project.
Enclosed are 2 copies of each of the proposed BCD Pilot Scale/Bench Scale Applications for
alternatives for disposal of PCB contaminated soils from the North Carolina Warren County
PCB Landfill. The Division of Solid Waste Management (Division) will work with you to
facilitate a final response decision on these applications within an approximate 90 day schedule.
If any additional information is needed please contact the applicants directly and copy the
Division.
A major concern of the Division is monitoring chemical events in the proposed process. The
primary chemical concern is generation of dioxins and the process, or specific element of the
process, that results in that generation. The fate of dioxins including accumulation in residuals
and air emissions are major interests. It is the Divisions perspective that PCB's can be
effectively reduced to below the 2ppm PCB requirement. However, if there is an increase in
dioxins, especially in residuals to be left on site, it is questionable if BCD is a appropriate
technology for detoxification. The Division would appreciate careful consideration of this

aspect of the approval process. The North Carolina Ambient Air Quality Standard for dioxin
emission is 0.0030ng/dscm.
If I can be of any assistance for any reason, please contact me at [phone]. This project is
a priority for the Division and we are committed to assist you in any way we can.
