APACHE ENERGY GAS PLANT EXPLOSION — GAS DISTRIBUTION
I refer to the reported 365 terajoules of gas supply lost a day as a result of the gas pipe rupture on Varanus Island. (1) How much of the lost gas supply has been offset by — (a) extra gas from North West Shelf Joint Venture; (b) extra gas from other gas producers; (c) reduced mining industry gas, including at Murrin Murrin Joint Venture, BHP Billiton Ltd’s nickel operations, Alcoa’s smelter and Newcrest Mining’s Telfer mine; (d) reduced supply to the Burrup fertiliser project; and (e) reduced gas supply to Alinta’s contracted customers affected by its force majeure notices? (2) What was the average daily gas supply flow from all sources into each major gas pipeline before the accident, and what is it now? (3) How was the 365 terajoules a day of gas supply from Varanus Island distributed between each major pipeline before the accident? Hon KIM CHANCE

I thank the honourable Leader of the Opposition for some notice of the question. (1) (a)-(b) Approximately one-third of the lost gas supply has been offset by Woodside and other gas producers. (c)-(e) These details are considered to be commercially confidential. However, the total amount of reduced demand is currently estimated to be around 160 terajoules a day. (2)-(3) A precise breakdown of these flows is considered commercially confidential information. A breakdown of losses by industry type and region is estimated as follows: mining and industry in the Pilbara have seen an approximate 45 per cent drop in gas supply; mining and industry in the goldfields have seen an approximate 20 per cent drop in gas supply; large industry and commerce and mining in the south west have seen an approximate 20 per cent drop in gas supply; and mid-sized industry and commerce in the south west have seen an approximate 25 per cent drop in supply.
