Hon SCOTT SIMPSON (National—Coromandel): I wondered if I could come back to the use of vocabulary. So in clause 4(2)(a) and (b), relating to "discharge", there are sort of nice words about including the "release, disposal, spilling, leaking, pumping, emitting, or emptying;", but then paragraph (b) goes on to say, "does not include—(i) dumping", and I'm intrigued to know why there can't be some consistency of vocabulary. "Dumping" is a pejorative word, whereas "release, disposal, spilling, leaking," is a much kinder use of the English language. It seems to me that there is a specific exclusion in the legislation that precludes the evil dumping but that allows for the inclusion of disposal, spilling, leaking, pumping, emitting, or emptying.
