Main issues, as the Inspector framed them

  • the effect of the proposal on ecology
  • whether the proposal is subject to the mandatory biodiversity net gain (BNG) requirement and, if so, whether it would be met
  • the effect of the proposal on the character and appearance of the area
  • whether the significance of the Cornwall and West Devon Mining Landscape World Heritage Site (CMWHS) would be conserved

What decided it

The failure to provide a Preliminary Ecological Assessment and to demonstrate that mandatory biodiversity net gain requirements would be met constituted significant harm that was not outweighed by the minor benefits of the proposal.
