4.4.1.1   Overall Protection of Human Health and the Environment
-- Alternative 1

Alternative 1 would protect human health and the environment in
the long-term primarily through treatment of the PCB-contaminated
material using HTTD.  PCB-contaminated material 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 at the CD sites.  The
majority of the waste material contaminated with PCBs would be
treated using HTTD.   The PCBs would be separated from
contaminated material through HTTD treatment, thereby reducing
the potential for the PCBs to released to the environment.  The
PCBs would be concentrated in a condensed oil waste stream, thus
significantly reducing the volume of contaminated material.  The
concentrated waste stream, as well as certain PCB articles such
as capacitors, would be treated at a permitted, 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.  Human health and the
environment would be protected in the short term by implementing
strict engineering controls on emissions from the HTTD unit.
