Progressive rehabilitation must commence when areas become available within the operational land.
- F7
Areas which are to be rehabilitated to native ecosystem must achieve a self-sustaining native ecosystem with species composition and distribution similar to an analogue site or another suitable alternative approved by the administering authority.
- F8
Areas to be rehabilitated must be rehabilitated to the landform design criteria defined in Table 10 and the landforms must be stable.
- F9
Where reasonable and practicable, areas of the site where grazing is nominated as the post-mine land use must include native grass species endemic to the area. Permit OFFICIAL Environmental Authority EPML00969013 Residual voids outcome
- F10
Residual voids must comply with the following outcomes: a) Residual voids must not cause any serious environmental harm to land, surface waters or any recognised groundwater aquifer, other than the environmental harm constituted by the existence of the residual void itself and subject to any other condition within this environmental authority; and b) Residual voids must comply with Table 11.

- F11
The environmental management plan and plan of operations must be consistent with the geotechnical and erosivity assessment within three months of the completion of the assessment outlined in condition F10.
- F12
Cleared vegetation from the site must be managed in accordance with the following hierarchy: a) Reuse, e.g. use of logs and tree stumps as shelter for fauna in rehabilitated areas; b) Recycle, e.g. mulching of vegetation and use in rehabilitation on the site; and c) Other alternative management options implemented in a way that causes the least amount of environmental harm.
- F13
A weed management plan must be developed and implemented. The weed management plan must describe how weeds are to be managed in accordance with the Land Protection (Pest and Stock Route Management) Act 2002 and/or local government requirements for weeds not declared under state legislation. Infrastructure
- F14
All infrastructure constructed by or for the environmental authority holder during the licensed activities including water storage structures, must be removed from the site prior to surrender, except where agreed in writing by the post mining land owner/holder. Exploration
- F15
Disturbance due to exploration activities in areas not authorised to be mined must be rehabilitated in accordance with the provisions detailed in the Code of Environmental Compliance for Exploration and Mineral Development Projects. END OF SCHEDULE F Permit OFFICIAL Environmental Authority EPML00969013 Schedule G - Dams All dams
- G1
The holder of this environmental authority must ensure that dams are designed, constructed, operated and maintained in accordance with accepted engineering standards.
- G2
Except for dams affected by condition G3, the hazard category of dams must be assessed by a suitably qualified and experienced person prior to their construction, and then not less frequently than on an annual basis.
- G3
The hazard category of dams constructed prior to grant of this environmental authority, must be assessed by a suitably qualified and experienced person within six months of this environmental authority taking effect, and not less frequently than on an annual basis.
- G4
Where the hazard category of a dam is assessed as significant or high, the holder of the environmental authority must act immediately to ensure: a) The administering authority is advised of the current location and details of that dam; and b) That dam meets the hydraulic performance required of the assessed hazard category within six months of that assessment.
- G5
The condition of dams must be monitored for early signs of loss of structural or hydraulic integrity, based on the advice of a suitably qualified and experienced person. The methods of monitoring and frequency of monitoring shall be assessed by that suitably qualified and experienced person, based on the hazard category and particular circumstances of each dam.
- G6
In the event of early signs of loss of structural or hydraulic integrity, the holder of this environmental authority must immediately take action to prevent or minimise any actual or potential environmental harm and report in writing any findings and actions taken to the administering authority within 28 days.
- G7
The holder of this environmental authority must decommission each dam to a situation where ongoing environmental harm is prevented.
- G8
As a minimum, dams must be decommissioned such that they: a) No longer contain flowable substances; b) Become stable landforms; and c) Comply with rehabilitation requirements of this environmental authority.
- G9
The holder of this environmental authority must ensure that, where a current operational plan covers decommissioning and rehabilitation, those operations are consistent with the objectives in any design plan for the dam.
- G10
The annual inspection may be conducted as early as 1 September each year, but not later than 1 November each year, except that the assessment of adequacy of available storage in a dam must be based on dam levels observed in the month of October in the year that the inspection is conducted.
