About the company
Tetra Tech, Inc. 117-ECS (Environmental and Compliance Services Division) operates as a child division of the publicly held Tetra Tech, Inc. parent company, delivering environmental engineering, site remediation, geotechnical investigation, and construction inspection services to federal land and resource agencies as a prime contractor on full-and-open (non-set-aside) delivery orders and indefinite-delivery contracts. The division is headquartered in Billings, Montana, and competes without SBA set-aside designations; work is performed across Montana and South Dakota national forests, tribal lands, and other federal sites in the Northern Region.
The division's footprint is heavily concentrated with the Department of Agriculture Forest Service Region 1-Northern Region, which accounts for 15 of 38 awards (39% of total awards) and $16.3 million of $18 million in combined potential value (91% of the dollar total). Smaller work volumes flow to the Department of Health and Human Services Indian Health Service ($42 thousand across 2 awards), the Department of the Interior Bureau of Indian Affairs Rocky Mountain Region ($39 thousand across 2 awards), and the Department of Veterans Affairs (2 awards, value not itemized). This concentration reflects the division's positioning as a regional environmental remediation and mine site reclamation specialist for CERCLA, national forest management, and land restoration projects.
Tetra Tech 117-ECS holds a single-award $15 million IDIQ from EPA Region 1 (contract 1240LQ26D0006, awarded January 26, 2026, running through November 30, 2030) for Region 1 CERCLA Mine Reclamation support. Fourteen task orders placed under this IDIQ carry $1.3 million in combined potential value. Representative delivery orders include a $255,102 order from the Forest Service (August 4, 2026) for Beal Mountain Mine site work encompassing dewatering analysis, well testing, and heap leach pad emergency action planning (completion March 15, 2028); a $228,298 order (March 3, 2026) for Riley Pass 2026 construction inspection in Ludlow, South Dakota (completion December 31, 2026); and a $160,782 order (June 8, 2026) for the Beal Mountain Mine CERCLA project at Beaverhead-Deerlodge National Forest (completion December 31, 2027). Work encompasses geotechnical investigation, environmental site assessment, revegetation and subsidence monitoring, air quality monitoring during construction, and construction inspection across multiple national forests and abandoned mine sites.
Activity has accelerated sharply in recent years—one award each in 2009, 2013, and 2016 through 2024, then fifteen awards in 2026 alone—driven by mine reclamation task orders under the EPA IDIQ. Thirteen awards carrying $1.3 million in combined potential value face ultimate completion within the next twenty-four months, creating recompete exposure on the division's primary EPA vehicle when that contract approaches renewal. Tetra Tech 117-ECS maintains 100% of its recent footprint as prime work, with no subcontractor role in the sampled awards. The primary capability categories span engineering services (19 awards), environmental consulting services (5 awards), and remediation services (3 awards), concentrated in PSC codes for architect-and-engineering general services and environmental systems protection.
