Rocky Mountain Arsenal Remediation

Rocky_Mtn_Arsenal

During World War II, this 27-square-mile chemical weapons facility was critical to our nation’s defense. Years later, portions of the historic site were left contaminated due to accepted disposal practices from half a century ago—presenting a complex challenge for Tetra Tech scientists and engineers.

 

From 1997 through 2011, Tetra Tech managed and executed effectively the $1.2 billion, 14-year Program Management Contract (PMC) at Rocky Mountain Arsenal (RMA). The PMC was a performance-based time and materials with award fee IDIQ contract, among the US Army’s largest, most complex, and highly visible environmental cleanups ever executed.

 

RMA is a 27-square-mile (17,000 acres) CERCLA Superfund site, the former location of a chemical and incendiary weapons and pesticide manufacturing and demilitarization facility. The PMC involved 3,000 acres contaminated with pesticides, solvents, heavy metals, and agent byproduct. Restoration required moving 13 million cubic yards (cy) of earth and cleanup of 800 contaminated structures with 27 contaminants of concern, in addition to sarin and mustard (chemical warfare material) and munitions and explosives of concern.

 

The RMA National Wildlife Refuge is just 10 miles northeast of downtown Denver, Colorado. It is home to more than 330 species of animals, including wild bison, deer, coyotes, prairie dogs, bald eagles, and burrowing owls. The refuge, currently occupying 12,000 acres, is the result of one of the nation’s largest and most challenging environmental cleanup projects.

 

Highlights:

  • Completed the PMC 2½ years ahead of schedule with a cost savings of approximately $200 million
  • Managed 460 task orders covering a diverse mix of design, construction, restoration, and remediation
  • Achieved site closure for 146 sites, deleted 15,900 acres from the NPL list, and transferred 14,700 acres to the USFWS
  • Awarded $638 million to subcontractors via 300 subcontracts; 43 percent of the awarded dollars went to small business concerns
  • Averaged more than 95 percent award fees through 26 performance periods and a composite rating in the “superior” performance category
  • Achieved OSHA VPP Star Status in 1999 and recertification in 2002 and 2007
  • Achieved over 6 million hours at RMA with no lost time incidents, including during MEC and CWM tasks
  • Invested more than $575,000 in local community charities, schools, and organizations
