While the 7x expansion works from 60 to 85 mtpa were being constructed, DBCT Management received access applications for additional terminal capacity – i.e. beyond 85 mtpa and up to 153 mtpa.
A study began to investigate the possibility of such an expansion; however, this study was discontinued when it appeared that a new terminal at the nearby Dudgeon Point would attract greater user support. The cost of the study up to that point was $5.8 million.
In March 2013 DBCT Management requested approval for a $0.0065 per tonne increase in its reference tariff based on the $5.8 million expenditure .
In April 2013, following review of the prudency and necessity of the expansion costs related to the expansion study, the QCA approved DBCT Management’s application and adjusted DBCT revenues and tariffs accordingly.
