As i have mentioned before, the 14 is far better suited to Birdwood than the QRV (my personal opinion is that a second heavy tanker would be more appropriate, however we will have to see how the 14 goes first, it may surprise us!!).
To my knowledge ex-Birdwood QRV is now a regional resource (much the same as Tanunda QRV) and although based from Mt Pleasant can be shifted anywhere at regions discretion...
I have no idea what went on at the state level, however there are some SFEC changes in the pipeline, as Birdwood and surrounding areas risks have increased substantially over the last 10 or so years.
