Waste Rock Seepage Issues, Water Licence N7L2-1616 (MVLWB, June 2000)
The Mackenzie Valley Land and Water Board denies BHP's request to suspend pH licence limits and instead directs enhanced monitoring and confirmation measures for waste rock seepage, particularly addressing potential acid mine drainage development at the Panda Waste Rock Storage Area draining to Beartooth Lake. The document includes regulatory correspondence, technical geochemical review findings confirming AMD formation, and meeting minutes regarding the 1999 Waste Rock Seepage Survey results.
