PASS in excess of the collective 300,000 tonnes or so per annum for Melbourne can still be taken in by
Melbourne landfill sites but it then has to compete with “normal” landfill. Landfill charges in Melbourne are
typically $140 to $150 per tonne. On top of that, PASS customers would have to pay a premium to the
landfill operators to cover the PASS mitigation costs of lime addition, mixing and handling. Hence they would
be paying over $150 per tonne.
Melbourne’s Looming Landfill Storage Problem
At the Victorian Waste Expo in October 2015, several industry speakers in a panel discussion said that
developed landfill space in Melbourne was now at a critical level and that they were concerned that the new
guiding principal for landfill planning in Victoria had become “Environmental Justice”.
With the spread of suburbia in Melbourne and the growing public attitude towards new landfill sites or
expansions of “not in my backyard”, the waste industry can only see the current landfill capacity problems
getting worse.
Melbourne’s Looming PASS Storage Problem
Melbourne in recent years has been finding space for collectively around 300,000 tonnes per annum of “15%
cover material” PASS in the city’s 17 landfill sites. If there is no space for additional PASS in Melbourne’s
developed landfill sites, where will the big expansion of probably over 1,000,000 tonnes per annum of
excavated PASS go? If there isn’t a solution, it is not clear how the rapid development of Fishermans Bend,
the Western Distributor Project and the Melbourne Metro Rail Project can proceed.
Nagambie Resources considers that the best environmentally-friendly, economic solution for Victoria’s
looming PASS problem is to take advantage of the 1990s-era, water-filled open pits at the degraded
Nagambie Mine site.
Nagambie Resources PASS Storage Charge
Nagambie Resources doesn’t intend to compete for the storage of the baseload circa 300,000 tonnes per
annum of Melbourne PASS that currently finds a home spread across the 17 metropolitan landfill sites under
the “15% cover material” EPA arrangement. The Company is only interested in bidding for the large
quantities of PASS that is proposed to come from the rapid development of Fishermans Bend, certain large
CBD high-rise buildings, the Western Distributor tunnel and the Melbourne Metro Rail tunnels.
If Melbourne landfills could take some of the PASS from the new developments, the cost to the developers
would be over $150 per tonne plus around $15 per tonne for trucking. The cost of trucking to Nagambie is
around $25 per tonne, giving an additional trucking cost to Nagambie of around $10 per tonne.
Nagambie Mining considers that, if it bids commercially less than $140 per tonne to store PASS under water,
it has the capacity to build up to and accept an average of around 1.0 million tonnes per year over a 6.2 year
life.
The potential scale of the PASS Project is illustrated below:
Total Capacity to Store PASS Under Water: 6.2 Million Tonnes
Potential Life of PASS Project: 6.2 Years
Potential Average Storage: 1.0 Million Tonnes per Year
Comparative Market Storage Charge: Over $140 per Tonne
Nagambie Resources Storage Charge: Commercially Less than $140 per Tonne
Environmental Aspects of Backfilling the Pits with PASS
The water in the two pits is strongly alkaline and provides a natural buffer for PASS storage. pH data (7.0
is neutral) from 2007 to the present is shown in Figure 1. pH measurements would be taken every week
during PASS storage and agricultural lime would be added to the water if required to ensure the water
remained alkaline.
