Expiration date: 4/12/2016

Summary: This document supplements the Environmental Assessment and Finding of No Significant Impact, Control of Saltcedar and Russian Olive, Fort Peck Reservoir, Montana (USACE, 2013). The December 2013 EA disclosed the potential environmental impacts of providing chemical control of the invasive saltcedar and Russian olive through the aerial application of the herbicides imazpyr and glyphosate for large infestations, and the application of the herbicides triclopyr, imazapyr and glyphosate through foliar, cut-stump and basal bark methods at the Fort Peck Reservoir in McCone, Valley, Garfield, Phillips, Petroleum and Fergus Counties, Montana. This Supplemental EA defines the potential environmental effects of using triclopyr and 2,4-D for aerial application of large infestations of saltcedar and Russian olive.

Geographic Scope: Fort Peck Reservoir, Montana

Impacts: None

Decision/Date: Made following close of public comment period.
