Issue |
Potential impact |
|
Visual |
Plant and power infrastructure, there may also be structures around any tunnels |
|
Ecology |
Habitat and species disturbance |
|
Hydrology |
Risk of contaminating wells, aquifers and watercourses |
|
Traffic & Transport |
Vehicle movements during operation and also construction & decommissioning |
|
Noise |
Noise creation from drilling |
|
Geology |
Seismic factors associated with drilling near faults, risk factors from gas pockets and other sub-surface substances. Risk of ground subsidence. |
