Remedial Design

Following the release of the EPA Record of Decision in 2013, Arconic (formerly Alcoa) has been conducting a series of investigations in the river in support of the remedial design. These studies included additional sampling and surveys as well as habitat assessment work. Specific information being developed includes identifying the final limits of where remedial work will be conducted and understanding current habitat conditions in support of future habitat restoration work. The development of the remedial design using the information developed from these studies is currently ongoing.

Prior to work in the river, Arconic will expand the existing secure landfill within the Arconic Massena West site and construct a staging area near the Route 131 bridge. This work is slated to begin in spring 2017 and continue through early 2018.
