Key legal question
Whether the municipality had standing and the administrative appeal was admissible
Extracted holding
The municipality was entitled to appeal within the limits of its protected public interests, but only the admissible and sufficiently reasoned parts of the appeal could be examined.
Extracted reasoning
As an opponent in the plan-approval proceedings and as a public entity protecting inhabitants from emissions, the municipality had standing. However, generic allegations without specific federal-law violations or factual errors were largely inadmissible.
