Quick Summary

The Environmental Protection Agency (EPA), specifically the Water, Tribal & Science Division, has issued a Sole Source Justification for the award of a BPA Call Order to TETRA-TECH, INC. for Technical Support for Assessment and Watershed Protection, focusing on TMDL development support for Oregon Waters. This action is justified as a logical follow-on due to the unique and specialized nature of the services and an urgent and compelling need driven by court mandates.

Scope of Work

This sole source award covers highly specialized technical support for the development of Total Maximum Daily Loads (TMDLs) for Oregon Waters. The services include, but are not limited to, temperature TMDL analysis, criteria application, model configuration, model scenarios, shade analyses, and attainment scenarios. The work is critical for the EPA's compliance with court-mandated deadlines related to Oregon TMDLs.

Contract & Timeline

  • Type: Sole Source BPA Call Order (under BPA Contract # 68HERC22A0021/68HERW26F0018)
  • Awarded To: TETRA-TECH, INC.
  • Authority: 41 U.S.C. 253(c)(2) in accordance with FAR 8.405-6(a)(1)(C) Logical Follow-on
  • Published: February 3, 2026

Justification Details

The EPA justifies this sole source award based on the services being a logical follow-on to existing work. TETRA-TECH, INC. possesses deep expertise and familiarity with the unique challenges of Oregon's temperature TMDL technical support, having developed a nuanced understanding of the region's environmental conditions and regulatory requirements. The projects are time-sensitive due to court mandates, creating an urgent and compelling need to minimize delays. Transitioning to a new contractor would disrupt progress, require significant time and resources for onboarding, and jeopardize project timelines, potentially leading to legal repercussions for the EPA, including contempt of court.

Risk Mitigation

Continuing with TETRA-TECH, INC. mitigates significant risks. Recent litigation (Northwest Environmental Advocates v. United States Environmental Protection Agency, 2017) mandates the establishment of 15 temperature TMDLs over a ten-year period, requiring strict adherence to court mandates and timelines. Any delays could result in the EPA missing deadlines and facing legal penalties. The current contractor's proven track record and established methodologies ensure efficient and effective project completion, leveraging their considerable investment in understanding the intricacies of temperature TMDL analysis.
