2. PROPOSED DISPOSAL OF PRODUCED WATER
At a presentation to a
public meeting at Gloucester on 16
May 2013, a manager of AGL, Mr Mike
Moraza, stated that
salt from produced water would not be removed from site to the Taree
waste disposal facility,
as had previously been
documented by AGL.
Also Mr John Ross of AGL stated that produced water would not be disposed into the
Avon River.
Mr Ross stated that it was intended
that the produced water would
be diluted
and used for irrigation in
accordance with a trial
that is detailed
on
the AGL website, reproduced below:
“AGL has initiated a produced
water irrigation trial
on its Tiedmans property that will involve
the reuse of up to
70 ML
of produced
water over separate areas within
the
Stage 1A/1B areas. Most water is to be blended
and irrigated over an intensively monitored 12ha
area”
