Response Assessment and Evaluation Services Contract II

EPA awarded Tetra Tech the second Navajo Area Abandoned Uranium Mines Response, Assessment, and Evaluation Services (RAES) contract, worth $65 million, to address risks to public health and the environment from former mines on Navajo land.

Under this contract, Tetra Tech will focus on providing technical support to EPA through all stages of work addressing abandoned Navajo uranium mines. At sites where EPA assumes cleanup responsibilities directly, the company will investigate mine sites, prepare analyses of possible cleanup plans, assist in designing final plans once they are selected, and provide technical support during and after cleanup actions. At sites where the EPA assumes an oversight role of others conducting investigation and cleanup work, Tetra Tech will support EPA in reviewing site reports, analyses of options, and remedial designs, and conducting field oversight during investigations and cleanup actions. Additionally, the company will work closely with EPA and other experts to guarantee technical consistency across the numerous parties working on Navajo mines to ensure that cleanups are conducted rapidly and effectively. Throughout all this work, the RAES II contract will support EPA’s coordination and outreach with its partners in the Navajo government, local Navajo communities, and many other stakeholders.
