| Milltown Superfund Photos: Hammering Away at the Spillway |
July 9, 2008 Work at the Milltown Dam continues as Envirocon excavators with hammer attachments break up the spillway, which is on track to be fully removed by fall. Check out the EPA’s recent updates, July 2 (PDF) and July 9 (PDF), for the latest on remediation activities. A recent photo overview of the spillway removal and sediment excavation follows after the jump.  Spillway in the foreground and confluence of the muddier Blackfoot and the Clark Fork bypass channel.

More than a million tons have been shipped to BP-ARCO’s repository at the Anaconda Superfund site.  A closer look at excavation.
