The recent consultation on proposed updates to the Significant Impact Guidelines 1.3 has now closed. Thank you to everyone who contributed. We aim to publish a revised version of the updated guidelines soon.

About this policy statement

The core purpose of these guidelines is to assist any person who proposes to take an action which involves a CSG development or a large coal mining development to decide whether the action has or is likely to have a significant impact on a water resource.

These guidelines should be read in conjunction with EPBC Act Policy Statement 1.1 Significant Impact Guidelines – Matters of National Environmental Significance.
