URANIUM MINE AND MILL CLOSURE
I managed the comprehensive, multi-phase closure design for a mill and mine site over a five-year period, coordinating a multidisciplinary team of over 30 scientists, engineers, field crews, and specialists. This work required navigating complex hydrogeological and geochemical processes through years of characterization, options analysis, and rigorous risk assessment.
Throughout the project, I worked closely with site operators, asset managers, and closure managers to complete and evaluate our designs, while supporting NRC and WYURP permitting processes. My role encompassed a broad range of technical requirements, from the reclamation of diesel-contaminated soil via landfarming to the characterization of pit lakes and the design of pit backfills and site-wide regrading. I also led the hydrological and hydraulic designs for surface water management, focusing on mass balance modeling and the optimization of evaporation pond designs to ensure the site met all long-term closure objectives.
​
The sheer scale of the project presented intricate risks that we had to carefully evaluate and weave into the closure options for both the mine and the mill. Addressing these challenges required multiple rounds of detailed options analysis, where I managed critical path cost evaluations and detailed project scheduling. This process was anchored by a high level of stakeholder engagement, including technical review presentations, meetings, and workshops designed to align our engineering solutions with regulatory and corporate objectives.
