The overall aim of WP5 is to perform a risk analysis of environmental impacts of UCG activities, exemplified by the selected pilot UCG site(s) in Romania. Identified environmental issues and legal requirements for UCG in the EU and Romania will drive this risk analysis.

Specific objectives are:

• Define a risk assessment framework which is appropriate for the analysis of UCG, exemplified by the selected shallow UCG demo site in Romania;
• To compile site-specific information and parameters which are important for the risk analysis, to define the UCG concept including measures to ensure containment of toxic substances resulting from the UCG process;
• To specify the performance indicators of the risk analysis;
• Build a database of risk factors for UCG;
• Identify and screen environmental risk factors for the selected demo UCG site in Romania, and develop and semi-quantitatively characterize scenarios;
• Evaluate UCG-related contaminants
• Assessment of the results from the semi-quantitative analysis on the basis of existing legal requirements
