Internationally agreed principles for risk assessment were applied for the development of the EIFDD. Through the hazard identification the following stressors were identified and included in the model development:
The DREAM model was developed further to carry out exposure modelling. Through a literature study, information for the effect assessment of the identified stressors was collected. Environmental risk is calculated in the risk assessment based on estimation of the PEC/PNEC ratios.
Comparison/validation towards field specific values has been performed using data from field data collection as part of the ERMS program and the Norwegian Oil Association's MOD database.
