About the company
Heliotech, a subsidiary of ST George Tanaq Corp (an Alaskan Native Corporation), delivers environmental remediation, site operations, and technical support services to the Environmental Protection Agency as a prime contractor, competing predominantly under small business set-asides (Total Small Business and full-and-open designations). The firm is self-certified as a small disadvantaged business and operates as a partnership or limited liability partnership headquartered in Anchorage, Alaska, with primary NAICS coding in remediation services and PSC coding in environmental systems protection.
Heliotech's federal footprint concentrates entirely on EPA environmental remediation work across the EPA Remedial Acquisition Framework: Environmental Services and Operations (ESO) IDIQ, which spans 35 task orders valued at $34.4 million in combined potential value. The vendor's customer concentration is severe: EPA accounts for 80% of recent awards by count, split across five regional offices. EPA Region 7 (Midwest) leads by dollars with 11 awards valued at $21 million combined potential value; EPA Region 5 (Great Lakes) follows with 18 awards but lower dollar concentration at $7.2 million; EPA Region 10 (Pacific Northwest), Region 4 (Southeast), and Region 8 (Rocky Mountain) round out the active set. Two non-EPA customers — the Department of Agriculture Forest Service's Southwestern and Pacific Southwest regions — account for $1.4 million combined potential value across 13 awards. A single funding line from EPA's Office of Land and Emergency Management carries a $530 million placeholder ceiling (the largest single award in the source data), and the Department of the Army Corps of Engineers anchors $99 million in potential value, though these appear to be IDV parent vehicles rather than active task order volume. The portfolio reveals a recent shift: activity ran two awards in 2022, five in 2023, and eight in 2024, then dropped to two in 2025 and four in 2026 — a contraction trajectory. Only six awards with $1.3 million combined potential value face ultimate completion in the next twenty-four months, limiting near-term recompete exposure.
Concrete project examples demonstrate scope across multiple EPA regions and contaminated-site types. Heliotech holds a $11.2 million firm fixed-price delivery order from EPA Region 7 (issued April 1, 2026, ultimate completion March 15, 2029) for technical oversight, field investigation, and technical assistance for environmental remediation in Southeast Missouri. EPA Region 7 also awarded $1.77 million (issued August 7, 2024, through August 12, 2029) for operations and maintenance of a hydraulic capture system at the General Motors Sioux City facility; Heliotech subcontracted 100 percent of hours to Seneca Companies, Inc. and Below Ground Surface Inc., recording 15 contractor hours in fiscal 2024 at a derived blended rate of $0.00 per hour (indicating pass-through subcontractor resource delivery). EPA Region 5 awarded $525 thousand on September 11, 2025, for environmental services and operations at the Town of Pines site in Valparaiso, Indiana. EPA Region 10 issued a $2.83 million time-and-materials delivery order on June 30, 2023, for maintenance, inspection, monitoring, and remedy repair at the White King Lucky Lass uranium mine site in Lakeview, Oregon, where Eurofins Lancaster Laboratories Environment Testing, LLC provided laboratory analytical testing as a named subcontractor; government invoicing through fiscal 2024 totaled $184 thousand across 2,687 contractor hours, with a blended prime-plus-subcontractor rate rising from $26.38 per hour in FY2023 to $72.69 per hour in FY2024.
The Service Contract Inventory reveals a delivery model rooted in subcontracting: across SCI-reportable prime contracts, 100 percent of contractor hours were performed by subcontractors, with 34 named subs reported across the prime record set. SCI-reported invoicing totaled $2.2 million in fiscal 2024 on 17 prime records, scaling roughly 8.0 FTEs (contract-level aggregation); median government-paid rates ran around $72.16 per hour, with senior labor pricing through $184.74 per hour. This is a partial view — SCI excludes goods, micro-purchases, and classified work, and Heliotech's larger ESO task orders may not be fully captured in SCI reporting thresholds or fiscal-year reporting windows. The vendor operates as a 100% prime contractor across the award portfolio (55 prime awards, zero subs), positioning it as a prime vehicle for EPA regional offices rather than as a subcontractor feeder to larger systems integrators. The narrowness of the customer base — EPA Region 5 and Region 7 account for 80% of awards — and the collapse in award volume from 2024 to 2025–2026 suggest customer concentration risk and potential pipeline vulnerability in a relationship-driven market where ESO task order flow depends on regional EPA office funding cycles and remediation site demand.
