About this award

Written by GovTribe AI ·

Tetra Tech, Inc. received a $3.39M delivery order modification (P00006) under the Navajo Area Uranium Mines Response Assessment and Evaluation Services II (NAUMRAES II) contract from the Environmental Protection Agency (EPA) Regions 6 and 9. The modification extends the period of performance through December 31, 2026, and adds an additional alternate task order for removal site evaluations (RSE) at the Skyline Abandoned Uranium Mine (AUM), which encompasses the Skyline Mine and Utah No. 1 Lease located in Oljato-Monument Valley, Utah and Arizona. The contract employs a time and materials pricing structure with no small business set-aside designation, reflecting Tetra Tech's status as a large business contractor. The underlying NAUMRAES II IDIQ vehicle, valued at $65M, provides the framework for technical assessment and remediation services related to abandoned uranium mines on Navajo Nation lands.

The award includes four subcontractors supporting specialized project functions: Gel Laboratories LLC (woman-owned small business) provides laboratory analytical services with a February 2025 modification to increase funding for additional sample analyses; Sundance Consultants, LLC (Native American-owned small business) delivers cultural resource surveys and monitoring services with a May 2024 modification expanding monitoring days; Validata Chemical Services, Inc. (minority and woman-owned small business) furnishes data validation services as of November 2023; and Environmental Data Services, LIMITED (small disadvantaged and economically disadvantaged women-owned small business) provides third-party data validation services awarded in April 2025. These subcontractors support Tetra Tech's comprehensive environmental remediation and assessment capabilities across the Skyline AUM removal site evaluation project.
