The U.S. Department of Energy (DOE) announced in June that CH2M HILL LLC was selected to provide environmental restoration services at the Hanford Site's Central Plateau under a $4.5 billion, 10-year (five-year base period and five-year option period) contract. The Hanford Site is a DOE facility covering over 500 square miles north of Richland Washington.' As part of the CH2M HILL team that began work on October 1, 2008, INTERA is leading the site-wide flow and transport modeling, probabilistic risk assessment, and quality assurance (QA) scope areas. Dr. Alaa Aly, a Senior Engineer with INTERA, is serving as the Plateau Remediation Contract (PRC) Manager of Computational Analyses and leading the INTERA modeling team's efforts. Mr. Joe Archuleta, who recently retired from Sandia National Laboratories to join INTERA's PRC Team, is leading INTERA's QA activities. The PRC is focusing on the safe, environmental cleanup of the Central Plateau of DOE's Hanford Site. INTERA has hired 10 new staff members to support this contract and has opened an office in Richland, Washington in anticipation of additional growth. INTERA's President and CEO, Dr. Marsh Lavenue, stated: "INTERA is pleased to be part of the CH2M HILL PRC Team. This project provides us with the opportunity to apply lessons learned from both our domestic and international performance assessment projects to support risk-based prioritization of remedial decisions at the Hanford site. The outstanding team that CH2M HILL has assembled brings a proven track record of completing large and complex remediation projects. We feel fortunate to be working with them on this high profile project."
