HERMISTON — The Umatilla Chemical Agent Disposal Facility reached “substantial construction completion” 19 days ahead of schedule, the contractor announced earlier this month.

Washington Demilitarization, responsible for the construction, announced May 16 that U.S. Army Corps of Engineers had concurred with the last of the system “turnovers” to a phase they refer to as “cold commissioning,” during which various testing is done.

“Reaching this milestone early is a major victory for this site, especially considering the outstanding quality of work done in the field while maintaining superb safety and environmental records,” said Washington Demilitarization Company Project Manager Loren Sharp. “Everyone at UMCDF can share in this success.”

Under their contract with the U.S. Army Program Manager for Chemical Demilitarization, Washington Demilitarization Company had to have the plant substantially complete by May 29. However, construction Manager DeWaine Kuehl said construction personnel decided as a group to try to beat the deadline.
