I, JOANNE JENNIFER BELL, Delegate of the National Offshore Petroleum Titles Administrator, on behalf of the Commonwealth–Western Australia Offshore Petroleum Joint Authority hereby vary Pipeline Licence WA-5-PL as set out below.
- The First Schedule of the Licence is varied by deleting the words:
“The route of the pipeline shall be as described in the table below, from and including the boundary of Pipeline Licence WA-21-PL and WA-5-PL at the western end of the East Spar manifold at or about 7,707,290.78mN, 290,101.15mE to the pipeline licence boundary of TPL-12 at or about 7,714,306.54mN, 330,042.88mE along a line no point of which shall be more than 125 metres from the proposed pipeline route as shown in the drawing attached to the Licence as Annexure ‘A’. The coordinates given above are relative to UTM zone 50, with Central Meridian 117 deg E based on Geodetic Datum of Australia (GDA94).
