Project splitting in environmental impact assessment.

This paper discusses project splitting in environmental impact assessment (EIA), investigating the current state of knowledge through literature, legislation, case-law and practice, discussing problems and providing solutions. The focus is on Spain, but many of the conclusions are applicable worldwide. Project splitting is a much more common practice than generally accepted. The main efforts have been focused on preventing salami-slicing as a mechanism to avoid the EIA, but it is a much more complex problem, with different ways of splitting and reasons for doing so. Measures to avoid this practice should include strengthening the strategic environmental assessment, a greater involvement of the approval authority, specific prohibitions in regulations, using case-by-case examinations instead of thresholds, compulsory scoping and avoid the exclusion of project parts during the EIA.
