potential impacts on multiple environmental receptors.

Context establishment The scope of the risk assessment included construction and operation, decommissioning, closure and post-closure risks of the project in relation to environmental, social and economic values on both a local and regional scale. An initial project description along with existing condition reports was used as a basis for the risk assessments. The project description provided details of the project footprint, project infrastructure requirements as well as construction and operational activities and processes. The project description also established the base level of planned controls that are inherent in the project design. 5.2.2 Risk identification To determine risks, it is necessary to identify and describe cause and effect pathways for the project. Impact pathways identify the activity or event associated with project phases, and give consideration to assets, values and uses. This was done systematically for each discipline area to determine links between project activities and their subsequent consequences. The list of identified risks was developed using knowledge of the specific activities proposed for each component of the project across the phases, the local environmental context and understanding of the potential environmental or socio-economic impacts. The risk assessment for socio-economic impacts identified both the negative impacts and positive opportunities that may accrue from the project, in order to minimise the socio-economic Nolans Project Environmental Impact Statement Chapter 5 – Risk assessment Volume 1 Page 5-3 costs and maximise the benefits. This approach is in line with NT EPA Guidelines for the Preparation of an Economic and Social Impact Assessment. 5.2.3 Risk analysis and evaluation Risk ratings were established for each pathway by technical specialists assigning a level of consequence in accordance with consequence criteria for the project and a level of likelihood in accordance with likelihood descriptors (. Consequence criteria range on a scale of magnitude from ‘insignificant’ to ‘catastrophic’. Magnitude was considered as a function of the size of the impact, the spatial area affected and expected recovery time. These were influenced by the requirements of relevant legislation and guidelines. Some risk events can have consequences on multiple environmental receptors. To provide a meaningful and manageable risk register, these potential impacts were grouped as a risk event with each potential impact assessed separately. The initial risk rating considered the consequence and likelihood of the risk event with planned controls in place. These controls are consistent with the project description, regulatory requirements and management measures for projects of this nature (refer to the EMP contained in Appendix X).
