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.
