Focused Feasibility Study Wastebeds 1 Through 8
Wastebeds1-8 are located northwest of the City of Syracuse along approximately 2.1 miles of Onondaga Lake's southwest shoreline. They also border another Onondaga Lake subsite, Ninemile Creek. The Wastebeds consist primarily of inorganic wastes resulting from the production of soda ash using the Solvay process. Other waste materials associated with a variety of production processes from former Solvay Process, and later Allied Signal, operations were also likely disposed at the Wastebeds along with the Solvay process wastes.
This Site has been investigated during numerous field investigations starting in 1986 and continuing today. The results of these investigations are summarized in the Remedial Investigation Report (O'Brien & Gere, 2008b) which is being revised in response to NYSDEC comments.
The interim remedial program at Wastebeds 1-8, outlined in this Focused Feasibility Study (FFS) Report represents an important step toward the overall remediation of the site. This report documents the development and evaluation of Interim Remedial Measure (IRM) alternatives to address potential impacts to the Onondaga Lake and Nine Mile Creek remedies from the Site. Four IRM alternatives were evaluated in detail.
Following review of the evaluations documented in the FFS Report, NYSDEC and USEPA will document the preferred response action in a Proposed Response Action Document (PRAD). Following receipt of public comments on the PRAD, the selected response action will be documented in a Response Action Document (RAD). The proposed and selected response action may be different from that recommended in this Report. The final remedy that results from the site-wide Remedial Investigation/Feasibility Study process will be documented in a Record of Decision.
Several appendices could not be published on this web site because of their large size. They are available at the official document repositories for Onondaga Lake including: the NYSDEC office in Syracuse, the NYSDEC office in Albany, Liverpool Public Library, Moon Library at ESF, Camillus Town Hall, Solvey Public Library, the Onondaga County Public Library, Galleries Branch (downtown Syracuse), and Atlantic States Legal Foundation.
