The Framework assists with planning of future New Zealand mine developments on the West Coast of the South Island and in Southland. It is anticipated that the Framework will provide information that is useful during consent processes, access negotiation, and assessment of environmental effects. The intended audience for the Framework includes regulators, mining companies, land holders, and the community and the objective is to prevent, minimise, or mitigate mining-related impacts on water quality and aquatic ecosystems downstream of mines. Specifically the Framework provides information on collection of water, rock, and biological information used to predict water quality prior to mining, monitor discharges from mines and identify mining related impacts. The framework also provides information on methods and pitfalls in the interpretation of this information. In addition, the Framework includes information on state of the art techniques for prevention of poor water quality in mine drainages, optimal strategies for management of mine waste or overburden and remediation of mine drainages if necessary.

We consider the framework a living document and welcome feedback on your experiences of using it. Please provide comments or suggestions for improvements to Jo Cavanagh, and we will endeavor to include these comments in updated versions.
