After ammonia gas leaked from Orica’s Kooragang Island chemical plant on November 9 and made two people four kilometers away very ill, the Environment Protection Authority ordered the plant to shut down.
But because Orica is its major supplier, the Hunter’s coal industry has as little as three to four weeks of explosives in stock.
The largest Hunter mining company, Coal & Allied, told the November 22 Newcastle Herald it had cut production due to the explosives shortage.
