This is a Performance Work Statement (PWS) for remediation of a contaminated petroleum pipeline release site at the Former IHS/BIA Hospital-School in Kotzebue, Alaska, with a prospective contract award in 2026 and a 12-month period of performance.

The PWS outlines seven primary tasks: (1) Project Management & Planning, including kickoff meeting, work plan development, and logistics coordination; (2) Additional Site Characterization & Delineation, requiring advance test pits and soil borings at eight locations near monitoring wells MW11 and MW16 to identify alternate release sites and migration pathways; (3) Groundwater Monitoring & Product Recovery, involving evaluation and maintenance of 16 existing monitoring wells, water level and flow gradient measurements, and product recovery operations; (4) Soil Disposal and Characterization, managing investigation-derived waste under chain-of-custody with waste characterization sampling; (5) Institutional Controls (IC) Planning, developing IC mechanisms consistent with cleanup objectives including use limitations, excavation notifications, and long-term groundwater monitoring procedures; (6) Evaluation of Remediation Alternatives, including feasibility analysis for in-situ options and ex-situ landfarming considering Kotzebue's cold-climate and permafrost conditions; and (7) Reporting, requiring field activity summaries, contaminated soil delineation reporting, groundwater monitoring reports, and a final comprehensive report compliant with 18 AAC 75.335. The contractor must furnish all labor, materials, equipment, and technical expertise to plan and execute work in compliance with ADEC 18 AAC 75, EPA guidance, RCRA protocols, and all applicable federal, state, tribal, and local regulations. Work will emphasize groundwater monitoring and address data gaps along the former pipeline corridor, with deliverables including work plans, laboratory data packages, well integrity reports, and updated conceptual site models reflecting 2026 conditions.
