In the 1980s sediment spills from the constuection of the Berowra By-pass [F1] into Ku-ring-gai National Park established procedures for cleaning up spills of this kind. Yet it took months before the clean up of the Wollangambe River started.
The EPA must ensure it establishes standing procedures and writes up a 'how to' guide from the Clarence spill experience. Like first aid, with pollution events, quick action prevents harm. It is by a great deal of luck that heavy rainfall did not sweep coal fines all the way down the Wollangamba River.
