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. 

Archaeology

There may be archaeology present.
