. consideration of restrictions on
releases and spill water quality, and
regulatory and environmental
requirements;

. if some releases are acceptable,
containment of inflows to a
detennined stage with relevant flood
storage (such as the I: 100 AEP flood)
with no releases;

. by-pass provisions, diversions, and
temporary spillways during staged
construction over mine operational
life;

. regulator requirements for long term
safety, including identification of the
responsible owner when the mine is
closed,

9.5.3. Hydrology assessment.

This may need to consider long term wet
sequences and volumes, ,rather than peak
inflows.

Reference should be made to the ANCOLD
Guidelines on Tailings Dam Design,
Construction and Operation and to Appendix
2, sub-section A2.9 for reference to water
management and design flood and freeboard
requirements.
