The original powerpoint was fine. The council, being the council, have to upload their documents into a standard template and so some of the formating was lost.
The £5m was (I suspect) the work required to address a problem of deicing fluid draining off into the local streams and becks which had aroused the interest of DEFRA. Given this was a problem dating back to the days of council ownership, I'm sure the wording in the presentation was deliberate. It would have been an interesting moment in the room when that point came up.
It also explains why £5m of spend has not benefited the passenger experience - although the local fish and wildlife are probably feeling the benefit.
