4.4.3.1   Overall Protection of Human Health and the Environment
-- Alternative 3

Alternative 3 would protect human health and the environment in
the long term primarily through treatment of the PCB-contaminated
material using the DAVES process.  PCB-contaminated materials at
each of the sites would be excavated and transported to the CTF,
thereby reducing the potential for direct contact with, ingestion
of, or inhalation of contaminated materials.  The majority of the
PCB-contaminated materials would be treated using the DAVES
process.  The DAVES process separates PCBs from contaminated
material and concentrates them in a condensed oil waste stream,
thereby significantly reducing the volume of contaminated
material.  The concentrated waste stream as well as certain PCB
articles such as capacitors would be treated in an off-site
incinerator.  Waste material not contaminated with PCBs would be
properly disposed of in a permitted off-site facility.  The
short-term protection of human health and the environment during
waste treatment is a primary consideration.

term by implementing strict engineering controls on emissions
from the DAVES process.
