Comments: This final discharge point became subject to the MMER in August 2013. This final discharge point is already in reduced frequency since the effluent discharged is the same effluent as was being discharged through "Station 2.2"; this is still water treatment plant effluent and only the physical location of the final discharge point has changed.
