CICCC Update—18 June 2009 Meeting
At the June 2009 meeting of the CICCC, Terminals presented proposed new licence limits, and the reasoning behind the proposal. As the licence limits are strictly enforced (rather than being considered targets), the levels set must be capable of being met in worst case conditions (i.e. a ship discharge on a hot day with unfavourable winds). Some chemicals are no longer stored at the facility (Acrylonitrile, Ethyl Acrylate and Propylene Oxide) and will be removed from the licence.
The review considered both instantaneous and annual emissions, and the actual emissions in the period 2003 to 2008. In proposing new limits, Terminals generally applied a factor of three to existing emission levels. This has resulted in the annual limit for total sulphur oxides reducing by an order of magnitude, and significant reductions for three other chemicals.
The members of the CICCC were satisfied with the new limits proposed by Terminals, and the licence limits will now be finalised by the EPA.
Terminals is proposing to install additional equipment to allow the equivalent of a "pilot light" to burn during night hours when there is no load on the combustors. It is undesirable to allow the combustor to go out altogether, as start up from cold conditions can be slow and sometimes presents a few problems. On the other hand, maintaining the operational temperature of 750 degrees through the night, as presently happens, is wasteful of gas. The proposal offers a compromise condition that will avoid start-up problems, and will save gas and greenhouse gases.
Terminals has been in discussion with EPA concerning the use of the combustors for burning liquid wastes (usually water with a small percentage of hydrocarbons). EPA has asked for further analysis with the objective of improving greenhouse gas outcomes, and has suggested pre-heating of the liquid wastes. Terminals presented a schematic drawing to the CICCC showing the arrangement for pre-heating the liquid wastes. Discussion with EPA continues.
Oil Spillage on the Maribyrnong River
Quentin advised the meeting that there had been a spillage of approximately 1000 litres of black oil emanating from the Linfox site. An underground storage tank had overflowed, and the clean up is now complete.
Next meeting of the CICCC
The next meeting of the CICCC will be held on Thursday 10 September 2009 at the Maribyrnong Town Hall on the corner of Hyde and Napier Streets, Footscray at 6.30 pm. Any interested member of the community is welcome to attend the CICCC meetings. The date for the remaining meeting in 2009 is 10 December.
