Changes to proposals after assessment (s45C)

When implementing a proposal, proponents often want to make changes for various reasons. When these changes are minor, section 45C of the Environmental Protection act 1986 enables the Minister for Environment, or his delegate, the Chairman or Deputy Chairman of the EPA, to approve a change.

Only changes that do not have a significant detrimental effect on the environment additional to, or different from, the effect of the original proposal can be approved under section 45C of the EP Act.

The EPA subjects applications for minor changes to a rigorous, but timely, assessment.
