So to sum up your question Benny

NAG have two pits that can take over 6 million tonnes of PASS

NAG has EPA approval to take PASS

Victoria has numerous government projects that will have to dispose of huge amounts of PASS over the next 5-10 years

EPA guidelines govern disposal of PASS - and these guidelines state that PASS must be either disposed of underwater or treated with lime

Going rate for PASS is around $150 per tonne to dispose of with lime treatment - see above link

NAG have stated that they will be "commercially" less than $150 per tonne - whatever that may be.

Do the maths!
