13.8.1 The assessment outlined in this chapter has established that there are a number of sensitive
receptors in and around the proposed wind energy development site. The following provides a
summary of residual effects.
Surface Water Quality
13.8.2 A number of risks identified included the effects of the proposed wind energy development on
water quality. The watercourses within and adjacent to the site are considered to have ‘Poor’
to ‘Moderate’ baseline classification.
