BROOKSVILLE, Maine — The first phase of cleanup at the defunct, toxic Callahan Mine site is nearly complete, an environmental official told concerned residents here Wednesday.
The cleanup of polychlorinated biphenyls, or PCBs, at the former mine operations site has taken longer than expected, said U.S. Environmental Protection Agency Project Manager Ed Hathaway.
Cleanup of the PCBs and lead- and arsenic-contaminated soils began last year, but since this summer, EPA and state Department of Environmental Protection cleanup crews have filled 302 truckloads with PCB-laden material.
“As we did the work last year, we began to discover there were a lot more PCBs at the site than we had anticipated.”
Residents have wondered about truck traffic and the future of the site since the mine was green-lighted for the federal Superfund program in 2002. Now, they have an even heftier conundrum: The former mine’s owner, Smith Cover Preservation Trust, wants to give the site to the town as a gift.
The town is still weighing its options, Selectman Richard Bakeman said after Wednesday’s meeting, which was hosted by U.S. Environmental Protection Agency and Maine Department of Environmental Protection, at the Brooksville Public Service Building.
“The Trust, the EPA and the state have tried to interest us in taking it,” he said after Wednesday’s meeting. “But before we ever accept it, we need to find out whether there’s an interest” among Brooksville residents.
Bakeman was concerned that if the town took over the property, it would be liable for any future cleanup related to the former mining operation, but Hathaway said that regardless of who owns the site, the state will be responsible for ensuring its mining past doesn’t pose a danger.
One resident, Jody Spear, asked Hathaway several questions about whether the site would ever be truly clean enough for marine recreation. The mine area encompasses Dyer Cove and Goose Pond, and abuts the Sedgwick River.
Hathaway said that when cleanup is over, the site will be fit for recreational use.
“There will likely be a continued restriction on groundwater wells and clam fishing, but not on surface water use like swimming and boating,” he said. Spear wasn’t convinced, and Hathaway said he was more than happy to bring health scientists to Brooksville to speak with concerned residents.
“If I felt there was a risk to anyone being on that pond, I’d tell you,” he said. “There’s no benefit for me not to tell you.”
The EPA received an additional $2.25 million this year (the cleanup last year cost $3 million) to fund the unanticipated second wave of PCBs. Hathaway said cleanup crews will leave by the end of next week, but there will still be small amounts of PCBs to remove next spring.
Still, even when all the PCBs are gone, it will be a while before the entire mine site will be cleaned up. After phase one, state and federal government officials are expected to take about two years to design and fund the rest of the cleanup.
Tons of waste rock material will be stored in the former mine pit, and the “tailings impoundment” — where leftover material from the ore separation process was dumped — will be capped with a geosynthetic cover to prevent contaminants from leaving.
More than 800,000 tons of rock bearing zinc and copper ore were mined at the Callahan Mine between 1968 and 1972. The complete cleanup effort is expected to cost about $23 million.

Unfortunately a common scenario, corporation extracts profits from community, leaves with the money, also leaves waste for tax-payer clean up. Greed over responsibility everytime.
Yes, “we (the private sector) built that”, and now we expect you, the public sector, to clean up the mess we made.
I guess what the right would want is the ability to simply walk away from the mess and leave it as a mess without wasting taxpayer dollars to clean it up.
and the left doesn’t want to actually set up a legal system where corporations would be held legally responsible for their effects upon other’s private property…
the very existence of the EPA and regs such as CERCLA are what ALLOWS these sorporations to run roughshod over individual private property owners, disallowing individual lawsuits against the offending corporations…
both the left and the right have one goal in sight, corporate profits that will, in turn, work their way into the campaign funds for the next election
What do you expect when you have progressive corporate shelters built into government such as the EPA, USDA, FDA, etc. etc.?
So long as the mining corporation is following the “rules” of the day, there is no legal standing for individuals and those with abutting properties to make claims of nuisance or tresspass against these corporations.
Our alphabet soup, massive progressive government has hamstrung private property rights to the point where negative economic externalities are socialized to the detriment of us all under the guise of centralization and government ‘regulations’ (i.e. protectionist corporate handouts) that are supposedly intended to protect us, instead of corporate profits.
Unbelievable wants to give the site as a gift………….a 23million dollar expensive gift. Thanks but no thanks.
You can swim and boat……..no clamming and dont drink the water. How comforting.
Wow, no wonder we never caught any fish there when I was a kid. It was always a fun place to play and hunt for rocks.
Maybe we need to look at the bald mountain project a little closer before any mining begins there.
Perhaps I didn’t understand the article but where exactly are the PCB’s going? Yes the other materials will be capped on-site but where, specifically, are the PCB’s being trucked to?
