Tetra Tech Awarded $17.8 Million Environmental Remediation Program at Former McClellan Air Force Base

PASADENA, Calif.--()--Tetra Tech, Inc. (NASDAQ: TTEK) announced today that it has been awarded a $17.8 million contract with McClellan Business Park, LLC to perform environmental services for the privatized cleanup of portions of the former McClellan Air Force Base in California. The U.S. Air Force transferred portions of the former Air Force Base to McClellan Business Park prior to completion of remedial actions through a Findings of Suitability of Early Transfer. This is the third property transfer of its kind at the former base. Under this contract, more than 130 Installation Restoration Program (IRP) sites on over 600 acres will be evaluated, remediated, and closed, at which point the property will be available for development.

The former McClellan Air Force Base is one of the largest economic development and infill reuse projects in Northern California. The privatized cleanup and closure of IRP sites allows McClellan Business Park to continue its development of the property. When fully developed, it is estimated that some 35,000 jobs, over $6.6 million per year in local property tax revenue and $1.1 million per year in local sales tax revenue will be generated.
