The management of ARD and the assessment of its performance are usually described within the site environmental management plan or in a site-specific ARD Management Plan. This ARD Management Plan should integrate all the relevant concepts and technologies from the previous GARD Guide chapters and reference specific engineering design processes and operational management systems to be used. Additionally, an ARD Management Plan should outline clear accountabilities for specific site personnel to ensure that it is followed. A risk assessment tool should be used to identify the severity of the ARD issue and encourage proper ARD management. The development, implementation, and assessment of an ARD Management Plan and the process for its continuous improvement are described in this chapter. If the initial ARD Management Plan is robust, it can be more readily adapted to mine plan changes.
