Unfortunately I could not access your site for instructions as to forwarding a Senate Enquiry so I will register my concern re the terms of reference:

Due to inconsistancy in reporting requirements Heathgate and Honeymoon are required to report all spills based on terms under the trial drilling requirements. It was brought to my attention by Heathgate Mining at the Environmental Protection Round Table Conference that Western Mining had in fact had far greater spills- 500,00-Litres if my memory serves me correctly, yet they are not required to report these events. There needs to be considrable research into the potential impact of leaching into the environment from the actual Olympic Dam.

That monitoring spills/waste should be placed into the hands of more than one department- extend to Environmental Pollution Authority as well as PIRSA and RPA.
