RT Journal Article T1 Project splitting in environmental impact assessment A1 Enríquez de Salamanca, Álvaro AB This paper discusses project splitting in environmental impact assessment (EIA), investigatingthe current state of knowledge through literature, legislation, case-law and practice, discussingproblems and providing solutions. The focus is on Spain, but many of the conclusions areapplicable worldwide. Project splitting is a much more common practice than generallyaccepted. The main efforts have been focused on preventing salami-slicing as a mechanismto avoid the EIA, but it is a much more complex problem, with different ways of splitting andreasons for doing so. Measures to avoid this practice should include strengthening the strategicenvironmental assessment, a greater involvement of the approval authority, specific prohibitionsin regulations, using case-by-case examinations instead of thresholds, compulsory scoping andavoid the exclusion of project parts during the EIA.
