Question juridique clé
Whether the road had to be sanitized at source despite granted relief and exceeded alarm values.
Solution extraite
No further source measures were required because the road already had a noise-reducing surface and additional measures were not feasible or effective under the local conditions.
Motifs extraits
Sanitation measures under the environmental law aim at reducing excessive external noise, but here the available options at the source were practically ineffective, unfeasible, or disproportionate.
