Bridging the Gap: Integrated Facility Closure
ATC Williams provides closure and rehabilitation services for tailings, water, and mine waste storage facilities.
Our multi-disciplined, integrated approach produces safe, stable, non-polluting landforms. Stakeholder collaboration, governance and sustainable management of the environment guide our solutions.
Sustainable Closure and Rehabilitation
Our expertise in mine waste storage facilities, rehabilitation and water management complements our clients’ facility closure compliance and social responsibility objectives. With an extensive knowledge of tailings and mine waste, surface and groundwater management practices, and governance challenges, we support our clients in transitioning from operations to closure.
We deliver mine waste storage facilities that are safe, non-polluting, and aligned with post-mining land use. In this way, we develop innovative and cost-effective closure solutions for the entire life of the asset.
Comprehensive Closure Solutions
Our multi-disciplined Technical Communities provide clients with comprehensive capabilities and end-to-end solutions. We work closely with our Governance and Risk Assessment and Numerical Modelling Teams to cover all aspects of the mine closure lifecycle.

Philippe Garneau
Closure and Rehabilitation Technical Community Lead / Principal Engineer
Brisbane Office
Philippe Garneau, BEng, MSc, is a Professional Engineer focusing on mine waste management, environment, rehabilitation and closure.
He has worked in mining operations and consulting for nearly twenty years, managing projects at all stages of development, from scoping studies for greenfield sites to legacy assets. His work spans the globe, including the Americas, Oceania, Europe, Russia, Central and SE Asia, the Middle East and Africa. He is well-versed in culturally diverse environments and leads multi-disciplinary teams across time zones to complete closure studies and implement closure designs.
Philippe’s experience makes him a specialist in mine closure and mine waste management for mining operations at all stages of development. He understands the legislative requirements associated with mine closure in various jurisdictions and the applicable industry codes and standards, and he can develop governance structures. He is sought after as a technical lead for mine closure due diligence reviews for the mining financial sector and to conduct third-party reviews of mine closure plans and cost estimates for financial reporting. Philippe has developed the closure design of mine waste storage facilities and the initial design and management of these facilities.
John Milsom
Senior Principal Engineer
Hunter Valley Office
Based in our Hunter Valley office, John is a Senior Principal Engineer with thirty years of experience. His key practice areas include strategy selection and risk management, analysis and design of mineralised waste cover systems and facility governance within the context of the GISTM.
John joined ATCW following a 25-year career as a technical and business leader in mining and mineral processing operations, where he was directly accountable for decommissioning and rehabilitating a significant portfolio of facilities and assets. If you are dealing with challenges related to acid mine drainage, mine-site water management, rehabilitation liability planning, and decommissioning construction works, he has probably dealt with similar issues.
Darren Pemberton
Principal Engineer
Melbourne Office
Darren is a tailings and civil geotechnical engineer with over twenty years of consulting experience in Australia, the Middle East and South America. During his career, Darren has worked on projects in the civil, geotechnical and mining engineering fields with significant emphasis on the geotechnical and water management aspects of tailings and water storage facilities.
His speciality areas include geotechnical site investigations, embankment design, project management, stability and deformation analyses, foundation assessments, life of mine planning, feasibility studies, tailings and water management, geotechnical characteristics and behaviour of mine tailings, liquefaction analyses, construction management, quality assurance and quality control, preparation of operation and maintenance plans, dam surveillance and safety reviews, closure and rehabilitation of tailings and water storage facilities.
Darren has extensive experience in the closure of ash and coal tailings storage facilities and is an expert in the capping of soft tailings deposits. He works closely with clients to develop safe and cost-effective capping closure solutions. He is a strong advocate for closure planning at project inception, with regular closure plan updates throughout the project lifecycle.
Darren has managed multi-disciplinary teams to deliver successful closure of tailings storage facilities, which has included the development of initial closure plans, detailed investigations and design, technical support during closure construction activities and post-closure monitoring.
Nicola Logan
Principal Hydrologist
Brisbane Office
Nicola brings over twenty years of experience, specialising in mine water management, catchment hydrology, environmental flow assessment, and dam planning and yield assessments.
