The Western Australian Planning Commission (WAPC) has prepared a Region Scheme for the Peel Region, known as the Peel Region Scheme (PRS), pursuant to the Western Australian Planning Commission Act 1985. The WAPC, the Responsible Authority, proposes to recommend to the Hon Minister for Planning that the PRS be submitted to Parliament for final approval.

Section 48D of the Environmental Protection Act 1986 requires the EPA to report to the Minister for the Environment on the environmental factors relevant to the PRS and on the conditions and procedures to which the PRS should be subject, if implemented. In addition, the EPA may make recommendations as considered necessary.
