existing screening vegetation. This was the only impact anticipated during the operational phase.


135. Impacts for decommissioning were predicted to be similar to construction in the absence of further information on the likely process of decommissioning at this time. Though if similar mitigation measures are employed only minor adverse impacts should result. Where intrusive groundworks lie within the already disturbed footprint no further impacts will occur.
