4.1       ALTERNATIVES DESCRIPTION

This section describes the alternatives in detail.  Section 3.3.2
describes the support and secondary treatment process options
common to most of the alternatives.  Most of the alternatives
involve off-site treatment at a CTF and disposal of treated
materials at an off-site disposal facility.  Section 4.1.1
describes the CTF and solid waste landfill proposed by
Westinghouse; however, other locations for treatment and disposal
may be used.  Section 4.1.2 describes the primary treatment
technologies for each of the eight alternatives.  Section 4.1.2
also presents material flow diagrams for two possible scenarios. 
The two scenarios were developed to assess the impact that extent
of PCB contamination has on project costs.  Scenario 1 assumes
that some of the solid waste will be sampled and determined to be
nonhazardous in accordance with an approved excavation plan and
will be able to be disposed of in a nonhazardous waste landfill. 
Scenario 1 also assumes that all soil and rock, sediment, and
sludge are contaminated with PCBs.  Scenario 2 assumes that all
materials specified in the CD are contaminated with PCBs. 
Appendix A presents the detailed contaminated material volume
calculations and assumptions.
