Surat cumulative management area (CMA)
In areas of concentrated petroleum or gas development, the impacts on water levels in aquifers caused by water extraction by individual operations can overlap. The state government may declare these areas to be 'cumulative management areas' (CMAs).
OGIA prepares underground water impact reports (UWIR) for CMAs. These reports provide assessments of regional impacts on groundwater pressures and establish integrated management arrangements, such as regional monitoring strategies. These reports also identify individual responsibilities of tenure holders in implementing various aspects of the strategies.
When prepared, a UWIR is submitted to the Chief Executive of the Department of Environment and Heritage Protection for approval.
- On 18 March 2011, the Surat CMA (PDF, 608.9KB) was declared.
- On 1 December 2012, the Surat UWIR (PDF, 4.1MB) was approved and is now a statutory instrument under the Water Act 2000.
- The Department of Environment and Heritage Protection (EHP) has responsibilities in relation to the regulation of the overall environmental management of CSG activities including regulatory oversight and compliance of the provisions of the UWIR. For information about EHP's role in CSG, refer to the EHP website.
