Cumulative management areas

A cumulative management area (CMA) can be declared if an area contains 2 or more resource tenures, including tenures on which coal seam gas activities operate.

Declaring a CMA enables the Office of Groundwater Impact Assessment (OGIA) to assess potential future cumulative impacts on groundwater and develop management responses—such as monitoring programs—that help to manage those impacts.

It also enables responsibilities to be assigned to each tenure holder in the area for monitoring, bore assessments, and negotiating make good arrangements.

OGIA prepares an underground water impact report for each CMA.
