The purpose of these instructions is to assist proponents to provide the necessary information with their request to amend their proposal under section 43A of the Environmental Protection Act 1986 (EP Act).  

Proponents must seek approval from the EPA under section 43A of the EP Act if they wish to amend a proposal during assessment phase before the EPA publishes its assessment report.  

A request under section 43A will not be approved by the EPA if the requested amendment is considered to be a significant amendment.
