BROOKSVILLE, Maine — The Environmental Protection Agency will hold a public informational meeting at 7 p.m. Thursday, July 9, at the Brooksville Public Service Building to discuss the proposed $23 million cleanup plan for the Callahan Mine Superfund site.
The proposed cleanup action is outlined in the EPA Feasibility Study for the former mine site. The plan calls for the contaminated sediment in Goose Pond to be dredged and deposited in the former mine pit, which is underwater. Material from waste rock pile No. 3 and the former ore pad also will be deposited in the mine pit.
Not all of the materials will be placed in the mine pit. Some areas of polychlorinated biphenyl, or PCB, contamination and deposits of lead and arsenic will have to be removed from the site, he said. They will be disposed of at an approved site, he said. The plan also calls for a cap on the former tailings pile at the site.
The EPA also will develop restrictions that will prevent residential use or consumption of groundwater within the former Callahan Mine property portion of the site.
The proposed plan also includes a public notice regarding the impact of the cleanup on wetlands and information on the PCB cleanup.
A 30-day formal public comment period will be open from July 10 through Aug. 10.
The EPA also will hold a public hearing at 7 p.m. Aug. 6, at the Public Service Building. It will include a brief presentation followed by a public hearing to receive comment on the proposed plan. The hearing will begin at 7 p.m. at the Public Service Building.
A copy of the proposed plan, along with other technical documents related to the site, is available for review at the Brooksville Library and at the EPA Records Center at 1 Congress St. in Boston, Mass., from 10 a.m. to 5 p.m. Monday through Friday. Copies of the plan will be available at the July 9 and Aug. 6 meetings and on EPA New England’s Web site: www.epa.gov/ne/superfund/sites/callahan.
