Queensland Water Commission, Underground Water Impact Report for the Surat Cumulative Management Area, 2012 - Report and Data

## **Abstract** \n\nThis dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.\n\nThis dataset provides the data and PDF report supplied as the release of the 2012 Underground water impact report for the Surat cumulative management area. The following extract from the report is the general overview and purpose of the product.\n\n\n\nThe Petroleum and Gas (Production and Safety) Act 2004 and Petroleum Act 1923 authorises petroleum tenure holders to undertake activities related to the exploration for, and production of, petroleum and gas. This authorisation also includes the right to take or interfere with groundwater. However, the Water Act 2000 establishes responsibilities for petroleum tenure holders to monitor and manage the impacts caused by the exercise of these groundwater rights, including a responsibility to make good impairment of private bore water supplies. Those provisions exist because water is found in association with petroleum and gas and it is not practicable to manage the water separately.\n\n\n\nWhen water is extracted from a gas well, groundwater levels decline in the area surrounding the well. If there are multiple gas fields adjacent to each other, the impacts of water extraction on groundwater levels may overlap. In these situations, a cumulative approach is required for the assessment and management of groundwater level impacts. In Queensland, where this situation exists, a Cumulative Management Area can be established. Within a Cumulative Management Area the Queensland Water Commission is responsible for assessing impacts and establishing integrated management arrangements in an Underground Water Impact Report.\n\n\n\nIn the Surat and southern Bowen Basins, expansion of coal seam gas production is proposed, involving multiple developers adjacent to one another. As a consequence, the Surat Cumulative Management Area was established on 18 March 2011. As required, the Queensland Water Commission has prepared this final Underground Water Impact Report for approval to the Chief Executive of the Department of Environment and Heritage Protection.\n\n\n\nOn approval, the report becomes a statutory instrument under the Water Act 2000. Obligations for individual petroleum tenure holders for activities arising from the Underground Water Impact Report will then become legally enforceable. The Department of Environment and Heritage Protection will be responsible for ensuring petroleum tenure holders comply with their obligations.\n\n## **Dataset History** \n\nThis data and report were released by the Queensland Water Commission in July, 2012.

## **摘要**
本数据集及其元数据声明由第三方提供给生物区域评估计划（Bioregional Assessment Programme），并按原始提供的形式在此呈现。
本数据集包含2012年苏拉特累积管理区（Surat Cumulative Management Area）地下水影响报告（Underground Water Impact Report）发布时所附带的数据与PDF报告。下文摘自该报告的内容为本产品的总体概述与用途。

《2004年石油和天然气（生产与安全）法案》与《1923年石油法案》授权石油租赁权持有人开展与石油及天然气勘探、生产相关的活动，该授权还包括抽取或干预地下水的权利。然而，《2000年水法案》规定了石油租赁权持有人需承担的责任：对行使上述地下水使用权所造成的影响进行监测与管理，其中包括修复私人钻孔供水系统的受损情况。制定这些条款的原因在于，水与石油、天然气伴生，无法单独对其进行管理。

当从气井中抽取地下水时，气井周边区域的地下水位会下降。若存在多个相邻的气田，地下水抽取对地下水位的影响可能发生叠加。在此类情况下，需采用累积评估方法对地下水位影响进行评估与管理。在昆士兰州，若出现此类情况，可设立累积管理区（Cumulative Management Area）。在累积管理区内，昆士兰州水资源委员会（Queensland Water Commission）负责开展影响评估，并在地下水影响报告中制定综合管理方案。

在苏拉特盆地与南鲍恩盆地，拟开展煤层气开采扩张项目，涉及多个相邻的开发主体。为此，昆士兰州于2011年3月18日设立了苏拉特累积管理区（Surat Cumulative Management Area）。按照要求，昆士兰州水资源委员会已编制本最终版地下水影响报告，提交给环境与遗产保护部首席执行官审批。

获批后，本报告将成为《2000年水法案》规定的法定文书。此后，石油租赁权持有人因本地下水影响报告产生的活动义务将具备法律执行力。环境与遗产保护部将负责监督石油租赁权持有人履行其义务。
