Mine Water Treatment Strategy – Best Achievable Technology Assessment

project overview

Integrated Sustainability led an early-stage Best Achievable Technology (BAT-lite) assessment for a proposed metallurgical coal development. The focus was to identify viable treatment approaches aligned with local water chemistry and project phases. This work supported regulatory engagement, clarified mitigation strategies, and outlined next steps toward a full BAT evaluation.

project deliverables

• Reviewed environmental assessment materials and hydrological data to define site-specific constraints and inform regulatory context.
• Assessed potential water treatment needs across mine construction, operation, and closure phases based on projected discharge characteristics.
• Screened candidate treatment technologies for removal of selenium, nitrate, and metals, evaluating performance suitability under anticipated site conditions.
• Identified data gaps and recommended targeted fieldwork or modeling to refine future design inputs and performance expectations.
• Prepared a rationale for advancing preferred treatment approaches to support engagement in regulatory permitting discussions.
• Delivered a technical memorandum summarizing key findings, identified constraints, and phased treatment implementation pathways aligned with the mine development plan.
