The council will consider the relevant assessment criteria below for the restricted discretionary activities listed above.
1. The erection, upgrading, addition to or alteration of buildings, offices and accessory buildings for electricity generation facilities and any other structures associated with electricity generation.
a.Buildings
i.The proposed buildings should be in accordance with the development concept plan in Appendices 11.5.8.5 and 11.5.8.6.
ii.The building design, form, colour, materials, structure and external appearance should achieve the architectural features and the design objectives shown in the development concept plan.

iv.The development should comply with the control in clauses 2.16-2.21 relating to hazardous substances.
b.Landscape works
i.The proposed landscape works should be in accordance with the proposed landform and contours and the vegetation planting plan set out in Appendices 11.5.8.3 & 11.5.8.4.
ii.The planting proposals over the whole of the precinct should be consistent with the vegetation planting plan and appropriate for integrating the landform in the landscape and reducing the prominence and contrast of buildings and structures from public areas and surrounding sites (as existing at 1 August 2008) so that while the power station will be visible from some locations, it will not generally appear to be visually dominant in its rural setting.
iii.The development should comply with the controls in clause 2.6 for landscaping and in 2.11.5-2.11.8 for ecologically sensitive areas.
iv.The development should comply with the controls in clauses 2.25 for exterior lighting and glare and in 2.15 for fencing.
c.General matters 
i.The following general matters are accepted and will not be disputed:
development of the site in accordance with the outline plans in the appendices and development controls, including noise, is appropriate to achieve the objectives for the precinct
the constraints imposed on achieving these measures by the technical and operational requirements of electricity generation and transmission
the requirements for safety, operation, maintenance, and upgrading, of the electricity generation, transmission, telecommunications and other utility infrastructure should not be compromised.
4. Special information requirements
1. An application for an activity listed as restricted discretionary in the Activity Table must be accompanied by:
a. accurate perspective images of views of the buildings and infrastructure to be built, including form and elevation views
b. details of the site layout, security fencing and lighting to be used within the precinct
