Ambatovy Project

January 2006
Runoff and sediment controls will be implemented during site clearing and
preparation. Runoff from project areas will be contained for settling and treated
if necessary, using flocculants, prior to release into the downstream water basins.
Runoff from active pit sumps will be diverted directly to the ore preparation plant
if the pit is deemed to contain elevated levels of chromium. Runoff and
clarification ponds will be managed to replicate the natural variability associated
with high and low flows. Storage will be provided in the runoff collection ponds
to attenuate peak flows.
Stream flow monitoring will be conducted in basins downstream from the mine
to help define flow variability and to ensure downstream flow needs are being
met, at least to the extent that they are met under baseline conditions. Water
quality will be monitored at all clarification pond outlets, and downstream areas
including the Torotorofotsy Wetlands during both wet and dry seasons.

Flora and Fauna Management Plans
Two on-site protected areas will be established on areas of azonal habitat near the
mine. An additional azonal off-site conservation area at Ankera will also be
established, pending confirmation that this is a suitable site.
Vulnerable plant and animal species will be translocated before construction.
Plants will be transplanted, cultivated or propagated within appropriate facilities,
and will be re-introduced to other lands or reclaimed areas as appropriate. Where
feasible, selected listed International Union for the Conservation of Nature
(IUCN) and Convention on International Trade in Endangered Species of Wild
Fauna and Flora (CITES) fauna species will be translocated to similar habitats.
Monitoring will be carried out to determine the success of such translocation and
transplanting activities.
The ecological stability of azonal conservation areas will be monitored,
especially with reference to effects of air emissions and edge effects. Research-
based reclamation trials will be established to test the success of different
reclamation techniques.
A consultation process will occur to determine whether the forest management
plan affects land use capability of specific individuals in a net negative manner,
either due to loss of resource or change in access. Unresolved claims will be
compensated for.
