About this vehicle
EPA Region 7 established this Master IDIQ for environmental consulting services supporting the Superfund Technical Assessment Response Team IV (START IV) program, with no ordering deadline specified in the source. Ordering has been inactive since August 2020, five years ago—the most recent task order award dates to that month, and the portfolio shows a sharp decline in annual ordering activity, dropping from 54–61 orders per year in 2016–2018 to just 8 orders in 2020. With $301.5 million of the $306.8 million combined potential value already obligated (98%), this vehicle is substantially exhausted and no longer a pursuit target unless reinstatement or successor vehicle activity emerges.
Work under START IV spans environmental remediation, Superfund site assessment, time-critical removal actions, preliminary assessments, hazardous ranking system scoring, field sampling and analysis, emergency response support, equipment management, health and safety readiness, and capacity building. Pricing structures vary—labor hours, firm fixed price, time and materials, and fixed price award fee all appear across the portfolio, reflecting the mission-driven, reactive nature of environmental emergency response.
Tetra Tech, Inc. dominates by order count (217 awards), though Weston Solutions Inc. leads by potential value ($160.6 million across visible entries), with WSP USA Solutions Inc. holding $42.3 million in 84 orders. These three primes account for approximately 93% of all task orders and roughly 80% of combined potential value. The remaining six contractors hold a long tail of smaller awards, indicating a heavily concentrated competitive landscape.
Customer concentration mirrors geographic structure: EPA Region 7 placed 213 orders ($34.4 million potential value), followed by Region 10 (81 orders, $42 million), Region 9 (46 orders, $58.3 million), and Regions 4 and 5 with 27 and 23 orders respectively. All 411 task orders carry no set-aside designation, making this an unrestricted vehicle. Task-order values range widely, from under $10,000 for site-specific assessments to multi-million-dollar emergency response efforts such as 2017–2018 California wildfire response orders (e.g., $8.6 million, $7.3 million, $3.5 million obligated) and major removal actions. Place of performance concentrates in EPA Region 10 states (Alaska, Oregon, Washington, Idaho) and Region 7 states (Iowa, Missouri, Kansas, Nebraska), with dispersed site-specific work nationwide.
