Office of Groundwater Impact Assessment

The Office of Groundwater Impact Assessment (OGIA) is an independent entity established under the Water Act 2000.

OGIA is responsible for assessing and managing the impacts of groundwater extraction from resource operations in cumulative management areas (CMAs). We also provide advice on related matters outside CMAs.

Role and functions

Our core functions are to:

  • undertake evidence-based independent scientific assessment of cumulative groundwater impacts from resource operations
  • set management arrangements within the CMA
  • assign statutory responsibilities to tenure holders for the implementation of management strategies within CMAs.

These assessments and management arrangements are set out in an underground water impact report (UWIR).

So far, there is only 1 CMA in the state - the Surat CMA, established in 2011 in response to coal seam gas development. The first UWIR for the Surat CMA was prepared in 2012, followed by the second in 2016. Those reports are now superseded by the 2019 Surat UWIR.

On matters relating to groundwater impacts from resource development, we also:

  • provide advice to the Department of Environment and Science (DES)
  • maintain a database of information.

OGIA's functions in relation to groundwater impact assessment and management from petroleum and gas (P&G) development have been in place since 2011.

From 6 December 2016, the legislation was amended to provide a more consistent approach to managing underground water impacts from both mining and P&G development. As a result, our existing role has expanded to include relevant mining development.

Funding and administrative arrangements

OGIA is housed within the Queensland Department of Natural Resources, Mines and Energy, which provides corporate and administrative support.

OGIA is entirely funded through an annual industry levy. The majority of the levy is paid by coal seam gas operators within the Surat CMA.
