Now there is a further section: the amendment to section 222(1)(b)(i) in clause4(2) refers to dumping, but immediately above that it refers to discharge, and I'm wondering why the rather more pejorative term "dumping" is used rather than "discharge" and why there isn't some kind of consistency in terms of the vocabulary around those matters. I'm hoping the Minister may be able to give some clarity on those. I've got some other questions later.
