Environmental Impact

Initial Environmental Assessment indicates minimal impact.

  • Physical works minimised
  • Low impact on watercourses, habitats, landscape etc.
  • Technology regulates traffic flows – easing some vehicle emissions

Main risks:

  • Air quality
  • Visual impact
  • Noise

Currently undertaking screening exercise to determine requirement for statutory Environmental Impact Assessment
