(1) Yes, a section of the WA Oil gravel pit had been partially rehabilitated. The rehabilitation was not entirely successful due to drainage issues and inconsistency of the natural fall of the land. Consequently, the gravel pit required clearing, filling and grading to meet rehabilitation objectives outlined in the rehabilitation plan approved by the Department of Mines and Petroleum in 2011.
(2) Rehabilitation activities took place in 1998 and 2007.
(3) 3.92 hectares was subject to rehabilitation works with 2.22 hectares being successfully rehabilitated and 1.70 hectares being unsuccessful.
(4) 7.17 hectares.
(5) 3.25 hectares.
(6) 7.17 hectares.
(7)-(8) The pit is currently being partially filled as part of a staged approach to rehabilitation. A portion of the site is also being used as a laydown area for the Gorgon project. Under Section 91 of the
Land Administration Act 1997
, Licence 00043/2010_1_58, the Gorgon project has tenure over previously cleared areas of the WA Oil gravel pit and laydown is an approved use.
(9) The area approved for Gorgon project laydown is 4.95 hectares.
(10) The gravel stockpiles have been moved to WA Oil lease sites elsewhere on Barrow Island, where the material is being utilised for the construction of new well pads and road maintenance.
(11) Yes, the removal and use of gravel is managed under the Barrow Island Joint Venture Environmental Management Program for the WA Oil operations, which has been approved by the Department of Mines and Petroleum.
(12) Yes, the Gorgon Joint Venturers committed to use previously disturbed areas such as the WA Oil gravel pit to limit the Gorgon project's footprint.
