maximising the efficient use of water<br />
improving stormwater management<br />
during high rainfall events<br />
modelling groundwater drawdown and<br />
recharge (post-closure)<br />
developing sustainable capping strategies<br />
for the tailings dam and waste rock<br />
dumps<br />
updating the Mine Closure Plan<br />
reducing EHM’s financial liability<br />
improving biodiversity and land use<br />
planning.<br />
Environmental protection<br />
expenditures<br />
In 2010 Ernest Henry Mining invested<br />
$2.9 million on environmental protection,<br />
management and initiatives.<br />
Managing environmental risks<br />
EHM continues to maintain its area specific<br />
environmental Aspects and Impacts<br />
Registers. These registers are used to monitor<br />
controls that are implemented to minimise<br />
environmental risks. They also identify where<br />
additional controls can be implemented to<br />
further reduce environmental risk at the mine.<br />
The main risks and controls identified in<br />
these registers are integrated into the budget<br />
planning process.<br />
Continuous environmental<br />
improvement<br />
In 2010, EHM continued to manage<br />
an Environmental Improvement Plan<br />
(EIP), which listed key environmental<br />
improvement initiatives developed from<br />
the Aspects and Impact Registers. An EIP is<br />
developed annually to encourage continual<br />
environmental improvement at our operation.<br />
Our main focus during the year was further<br />
improving water use efficiency and the<br />
management of stormwater on site.<br />
