Delivered on: 11 January 2002
Exerpt from pages 19-20:
” (g) The existing overhead 11 kV feeder lines connected to the substation (other than any 11 kV feeder line in Sewell Road) shall be reverse phased (or alternatively configured) to the nominated junction of eack feeder line as shown on Drawing Number 5 to achieve the minimum Average Magnetic Flux Density levels that are reasonably practicable with the objective of achieving where reasonably practicable an Average Magnetic Flux Density not exceeding 4 milligauss at the Locations identified in paragraph (k) (iv), (v) and (vi).
(h) At any of the Locations identified in paragraph (k) (i), (ii) and (iii) the Average Magnetic Flux Density caused by the substation, the feeder lines connected to the substation or any distribution transformer, shall not exceed (4) milligauss except:
(i) during a declared state of emergency; or
(ii) for a period not exceeding 14 calendar days in total in a calendar year in the case of:
