High Hazard Management LLC

High Hazard Management LLC, a Hawaii-based limited liability company, operates exclusively as a subcontractor delivering environmental and remediation subject-matter expertise to federal agencies, with all recent work routed through Weston Solutions Inc. on EPA Region 9 Superfund programs.

The vendor's federal footprint is nascent and narrow. Three subcontract awards placed between January and November 2025 total $310 thousand in obligated federal dollars. All work flows through the Environmental Protection Agency Region 9, which accounts for 100% of recent awards, and sits on a single parent vehicle — the Superfund Technical Assessment Response Team V — where High Hazard Management has delivered three task orders. The awards span lithium-ion battery subject-matter expertise and remediation services: a January 2025 modification to increase funding on an existing task order (SME Services) by $24 million, a September 2025 new task order for lithium-ion battery SME work on the Ukumehame Batteries A9FF remediation site, and a November 2025 follow-on task order for additional services on the same site. The vendor's category concentration aligns narrowly with environmental consulting services (3 awards, 3 out of 3 categorized).

Service Contract Inventory data shows minimal federal services reporting: a single SCI record in FY2024 in the subcontractor role, reflecting approximately 0.4 FTEs delivered to a federal service contract above the reporting threshold. SCI is a partial view excluding goods, micro-purchases, and non-federal revenue; this figure does not represent the vendor's total federal services volume or enterprise revenue. The company operates entirely as a sub to Weston Solutions Inc., a prime contractor on EPA Superfund work, with no prime contract awards or parent IDIQs in the source data. Competitive exposure is concentrated to the Weston Solutions relationship and Superfund technical services within EPA Region 9's remediation portfolio.
