The screening and the scoping stages are critical sequences of the EIA/SEA in the sense that they are moments when a cost effective approach addressing salient uncertainties may and should be designed. Left unattended, these uncertainties will set the case management on a destructive track. This is the case with the screening decision when the parties – stakeholders or the developer – fail to agree on how well the exemption copes with the residual uncertainty of the project’s consequences. The public may believe that this residual uncertainty is not so negligible and should not be disregarded. The developer may withdraw because – right or wrong- he does not acknowledge the uncertainties of consequences CA identify and mobilise to ask additional information (EIA). The scoping opinion is crucial insofar the scoping decision – “scoping opinion ” or term of reference “- becomes a problem because the absence of a shared problematisation of the EIA workprogram fosters public opposition to the relevance of the added information from an EIA and further to the decision grounded on this EIA. The specific objective of task 3.2. is to design fine-tunings to the screening and scoping
