Corresponding HGV increases of 14.0%, 17.9% and 2.4% are predicted at each of these locations respectively. 7.5.31 In accordance with the IEMA guidance, it is therefore considered that the construction traffic generated by the proposals would result in a negligible magnitude of change. In accordance with Table 7.2, the significance of effect would be negligible. 7.5.32 The construction traffic flows during a Saturday morning would be proportionately similar to the baseline traffic flows as those set out above. Therefore, the effect on a Saturday morning would be similar to the above (negligible). In accordance with Table 7.2, the significance of effect would be negligible during all periods. 7.5.33 Although the above has set out that the traffic generated during the construction phase would not result in any significant environmental effects, it is noted that the movement of abnormal loads sometimes requires separate consideration. 7.5.34 In order to ensure a robust assessment, it is therefore appropriate to consider the possible effects of the abnormal loads below. Given that the above assessments show there would be no significant effects as a result of the total construction traffic, and that the Swept Path Analysis (RPS Report Ref JNY7370-02), which accompanies this application, shows that the abnormal loads can be accommodated on the existing road network, the effects below have been considered in general terms for abnormal loads along the entirety of the access route.

Camilty Wind Farm • Disruption and driver delay – Any effects of delay to other road users would only be apparent during the movement of abnormal loads as a result of their large size and low speed rather than their numbers. The A801, A706 and A70 are single carriageway roads, the police and any other escort personnel would ensure that driver delay is minimised by identifying locations ahead of the abnormal load where it could stop safely to allow vehicles to pass. There would be 78 abnormal loads over the entire turbine delivery period and efforts will be made to undertake these outside of peak traffic hours in order to prevent any disruption or delay during these periods. It is considered that some driver delay could occur as a result of the abnormal loads, however the temporary nature and safe escorting of vehicles should be borne in mind. It is considered that the magnitude of change would be small to medium and the significance of effect of disruption and driver delay as a result of the abnormal loads upon receptors along the route would be slight to moderate. • Increased risk of accidents - There is a potential for effects on safety as a consequence of driver frustration related to the movement of abnormal loads. However, all abnormal loads will be under police escort who will not only assist the abnormal loads but will control any oncoming vehicles or vehicles following the abnormal load. This should minimise driver frustration and reduce the risk of accidents. It is therefore considered any magnitude of change would be negligible and the significance of effect of accidents and safety as a result of abnormal loads upon receptors along the route would be negligible. • Severance, Intimidation and Pedestrian Delay - An increase in vehicle numbers, particularly HGVs through towns and villages, could result in additional delays to pedestrians wishing to cross the road i.e. severance. HGV traffic, particularly abnormal loads, can reduce the amenity of pedestrian routes in towns and villages to the extent that pedestrians feel intimidated by the traffic. There would be 78 abnormal loads which could result in intimidation or pedestrian delay, however, these movements would be spread over the construction period and any effect would be infrequent. On this basis, it is therefore considered any magnitude of change would be negligible and the significance of effect of severance, intimidation and pedestrian delay as a result of the abnormal loads upon receptors along the route would be negligible. • Dust and dirt - HGVs have the potential to distribute dust and dirt from the proposed wind farm construction site onto the local road network and is mostly pronounced in the immediate vicinity of proposed wind farms access. All access roads would be constructed and surfaced in an appropriate manner and, combined with on-site construction management, it is therefore considered any magnitude of change would be negligible and the significance of effect of dust and dirt as a result of the abnormal loads upon receptors along the route would be negligible. • Visual effects - The movements of high-sided vehicles during the construction period could be considered visually intrusive. Any effect would be short-term and only occur during the movement of abnormal loads.
