URS Corp.'s work to destroy chemical weapons stored at the Umatilla Chemical Depot has been named Project of the Year by the Columbia River Basin Chapter of the Project Management Institute.
Semifinalists were the Capability Replacement Laboratory Project at Pacific Northwest National Laboratory under project manager James McClusky and the Hanford 200 West Pump-and-Treat System Project by CH2M Hill Plateau Remediation Group under project manager Michael Ostrom.
The URS work, led by project manager Steven Warren, included destroying nerve gas and mustard blister agent in rockets, bombs, projectiles, mines, spray tanks and ton containers. Before incineration started at the Umatilla Chemical Agent Disposal Facility near Hermiston, the depot had 12 percent of the nation's stockpile.
Construction of the incineration facility began in June 1997 and the final chemical weapon, a mustard ton container, was destroyed in October 2011.

The award was presented Friday night in Kennewick.
