WDNR GFT Phase 3 Fact Sheet


Courtesy of Minergy Corporation Limited

Following the release of the draft Lower Fox River Remedial Investigation/Feasibility Study (RI/FS) in February 1999, WDNR received a set of comments from Minergy Corp. (Minergy). Minergy’s comments suggested that a vitrification (melting) technology might be more effective and appropriate for dealing with contaminated sediments than some of the options in the RI/FS. WDNR contacted Minergy as a follow-up to their RI/FS comments. Minergy prepared a proposal for a multi-phased study to determine the cost effectiveness of this technology and the effectiveness of this technology to destroy organic contaminants (primarily PCB) and immobilize inorganic contaminants (primarily heavy metals). Minergy proposed a four phased feasibility study for the testing of a glass furnace technology including a costsharing proposal. With the assistance of a grant from US EPA’s Great Lakes National Program Office (GLNPO), WDNR accepted Minergy’s proposal to conduct the Glass Furnace Technology feasibility study. Also, recognizing the extreme scrutiny PCBs have been under and the need for a thorough independent evaluation of the contaminants’
fate, WDNR requested assistance from US EPA’s Superfund Innovative Technology Evaluation (SITE) Program. US EPA’s SITE Program has accepted the challenge of conducting the cost and treatment effectiveness evaluations for this project.
