Roughly 642,000 cubic yards of Milltown sediment has been shipped to BP-ARCO’s repository at the Anaconda Superfund site. CFRTAC coordinator Michael Kustudia, with assistance of pilot Gary Matson, recently flew over the repository and took these photos. The photo above shows the sediments being spread to form roughly a two-foot layer. More photos after the jump.
One train a day, with 45 rail cars, makes the trip to the BP-ARCO repository.
Milltown sediments, rich in both heavy metals and organic matter, are used to cap areas at the repository, which home to more than 300 million cubic yards of smelter waste.
This repository cell awaits capping.
