Editor's note

O. Reg. 137/07 amends Subclause 9.3.1.1.(4)(b)(iii) of Division B to substitute '15 M bars', written with a space between '15' and 'M' in the as-filed amending regulation; this map applies that wording. The e-Laws consolidation editorially closes the space, rendering '15M bars' to match the neighbouring '10M bars', with no amending regulation making the change. This map preserves the as-filed wording.
