The goal of the closure plan is the prevention, minimization, and control of risks and adverse impacts that may arise once operation has ended as concerns the environment and the health and safety of people. Cerrejón’s current operational plan is for a mine life of 23 years, with an estimated closure date in 2034. The Preliminary Closure Plan for Cerrejón's operations contemplates a closure period of five years and a post-closure period ranging from 10 to 20 years depending on the components (social, environmental, safety). It takes into consideration the contractual obligations and the agreements established amongst the stakeholders. The plan considers aspects regarding land reclamation, water management, dismantling of installations, safety issues, social engagement, future land use, and financial provisions to ensure its social-environmental execution and sustainability.
This plan contains the preliminary closure costs, with the estimated costs for the various proposed closure scenarios having a medium level of detail.
