It seems necessary to create a list of criteria and thresholds
used at the stage of qualification of projects for the EIA process
regarding mining projects which are accepted and applied by all
the EU countries. It might guarantee in all member countries the
same approach to environmental problems caused by future exploitation
of mineral resources and it would make it easier to carry
out cross-border EIA procedures in case of deposits located in the
vicinity of borders between countries. However, environmental
authorities should preserve their autonomy in deciding whether it
is necessary or not to conduct the EIA procedure, which would
allow to carry out regional and local economic development based
on exploitation of mineral resources.
