Question juridique clé
Whether the skip storage site in the forest required and could obtain a planning permit or exception under Art. 24 RPG.
Solution extraite
The installation was not zone-conforming and did not qualify for an exception permit; it was neither negatively nor positively site-bound and did not amount to a permissible partial change of the quarry operation.
Motifs extraits
A skip storage area is a permit-required installation. Outside the building zone, Art. 24 RPG requires a site outside the zone and no overriding interests. The project could in principle be realized in a building zone, so no positive site-specific necessity existed; its connection to the existing quarry was too minor and the operational identity was not preserved.
