The impact and risk analysis components of a bioregional assessment contribute to the body of knowledge about the risks and potential impacts of coal seam gas or coal mining development in a bioregion.
Products of these two components use the contextual information, outputs from model-data analysis and additional analysis to identify and assess the risks and potential impacts on water resources and water-dependent assets. The impact and risk analysis products highlight the potential hazards and hydrological impacts of coal or coal seam gas development and summarise their effect on landscape classes and water-dependent assets. In some cases, these products also consider the potential ecological impacts.
The bioregional assessments do not provide a full risk assessment such as that required by an environment impact statement of a proposed coal or coal seam gas development. The information presented in the impact and risk analysis products may contribute to and be considered by another, more extensive risk assessment.
