The EPA thinks the best choice is alternative 4. The plan calls for about 70% of the waste would be removed from the site by digging down 16 feet deep. Then a permanent cap would be placed on the area. It would cost about $246 million and take 5-years to implement.
Many residents said a partial removal is only a partial solution and when over 1,000 residents were asked during the meeting who would like alternative 4 not one person raised their hand.
5 years to fully implement at an estimated cost of $236,000,000. The EPA has identified this preferred
alternative over 7 others that were evaluated in the RIA/FFS — including no action, two cap-in-place
alternatives, and five excavation alternatives — each of which is described in greater detail below. The EPA
believes that this preferred alternative is protective and represents the best balance of the criteria prescribed
by the CERCLA, as amended, and the NCP.
The EPA is issuing this proposal as part of its public participation responsibilities under Section 117 of CERCLA
and 40 C.F.R. 300.435(c)(2) of the NCP. This proposal is intended to inform the community of the EPA’s
preferred alternative and to solicit public comments relating to the remedial alternatives evaluated, including
the preferred alternative. The final decision to amend the ROD will be made after consideration of the
comments received and any new information raised during the public comment period. Therefore, the public
is encouraged to review and provide comment on all remedial alternatives.
The Administrative Record file, including the RIA/FFS reports, is available on the EPA’s website at https://
semspub.epa.gov/src/collections/07/AR/MOD079900932. The EPA encourages members of the public to
review these documents to obtain facts about the Site and the activities that have been conducted as part of
the Superfund process.
