Appendix D Checklists for Tailings Disposal Activities D1 Items to be Included in an Operation Specific Management Plan Management plans should be produced and documented which should include descriptions of: • short, medium and long-term operational, objectives, targets and performance measurements • permits and approvals • type and quantity of required resources anticipated over the life-of-mine. • roles and responsibilities • site selection and characterisation criteria • safety, environmental and engineering design criteria • communication procedures • construction, operating, decommissioning, closure and aftercare procedures and documentation requirements • monitoring, inspection, reporting and review requirements • knowledge and skills (awareness, training and competence) requirements and training records • record-keeping requirements including as-built data, historical development as well as issues and incidents • change management procedures. D2 Items to be Addressed if the Original Design of a Tailings Facility is Changed (As for New Facilities) Potentially feasible methods that should be considered should include: • disposal in disused underground workings as backfill material • establishing and maximizing the potential uses for the tailings material, such as use as a construction material, use as a soil ameliorant, and use in the restoration of other mine sites. • the use of suitable waste rock and soil emanating from the mining operations to form part of the tailings disposal solution to provide an integrated and cost effective solution. • the use of disused and exhausted open pits should be • conditioning the tailings within the metallurgical processes to minimise any environmental or safety • reduction of reagent usage to minimise the potential pollutants discharged to the environment, such as cyanide recovery or destruction. Technical studies that typically may be required include: • geotechnical site investigation • hydrological investigations and analyses • hydrogeological site investigation including characterisation of pre-construction, operational and post-closure flow patterns • geo-chemical characterisation of representative samples of all anticipated tailings materials including dynamic evaluation of the ARD potential, radiation, metals, pH, salts, potential for precipitation in drains Issued by the Anglo Technical Division page 35 of 47
