Kernrechtsfrage
Whether the printing plant had to be treated as a new installation or a materially modified existing one under noise law.
Extrahierter Entscheid
The annex housing all noise-relevant machinery was treated as a new installation, so planning values had to be met.
Extrahierte Begründung
The old part served only as storage and offices; the whole production had moved into the new annex, so the renewed part outweighed the remaining older part.
