Discharge Licences

At the October meeting of the qldwater TRG there was initial discussion on negotiations with DERM about discharge licences particularly with relevance to licence conditions. It was agreed that a secure web page be set up to allow interested councils to share licences and associated information. Any documents sent by interested councils will be available from this page and the forum below allows confidential discussions on the topic of discharge licences.

If there is another council that should be invited to join this discussion please add a request to the forum so that all interested parties have a chance to comment. Initially, only representatives present at the TRG meeting have been advised of this page. The following people currently have access.

Discussion group members: David Brooker, Peter Turl, Scott Casey, Anthony Lipsys, Jeff Rohdmann, John Betts, Jason Plumb, John Roworth, qldwater
