Question juridique clé
Whether the open-air cinema in the Erlenpark is subject to an environmental impact assessment as a major modification of an existing facility.
Solution extraite
The project is not a major modification within the meaning of the UVPV and therefore is not subject to EIA.
Motifs extraits
The additional use is limited, temporary, and causes only minor additional environmental burdens. Even considering traffic and air pollution, the change does not materially alter the environmental impact of the existing sports and leisure facility.
