Supervisory in which manner Don and at what level ?
I can think of two recent local wind farm projects where full and limited supervisory oversight was exluded with very bad results (in one case a very expensive and yet to be more expensive bad result) , both due to a lack of impact reports or failure to follow guidlines set out in the impact report .
Though there is another local one where the impact report was 90% wrong and the problems they envisioned actually turned to be benefits .
