* What is the proposed source of water for the proposal? (eg dam, bore, surface water
etc.)
Bore
2.8 Pollution
* Is there likely to be any discharge of pollutants from this development, such as noise,
vibration, gaseous emissions, dust, liquid effluent, solid waste or other pollutants?
(please tick) Yes If yes, complete the rest of this
section
No If no, go to the next section
* Is the proposal a prescribed premise, under the Environmental Protection
Regulations?
(Refer to the EPA General Guide for Referral of Proposals to the EPA under section
38(1) of the EP Act 1986 for more information)
Yes No If yes, please describe what category of
prescribed premise.
The proposed Yule River operations will involve the extraction, processing and transport of product as
part of its operations. Following the feasibility stage of the project, a Works Approval application was
developed to address the requirements of being a Prescribed Premises Type 12 „Screening etc. of
material‟. The Works Approval application was submitted to DEC Karratha Industry Regulation on the
16 th December 2011.
* Will the proposal result in gaseous emissions to air?
Yes No If yes, please briefly describe.
* Have you done any modelling or analysis to demonstrate that air quality standards
will be met, including consideration of cumulative impacts from other emission
sources?
Yes No If yes, please briefly describe.
* Will the proposal result in liquid effluent discharge?
Yes No If yes, please briefly describe the nature,
concentrations and receiving environment.
Toilet facilities will comprise a septic tank capable of receiving approximately 200 L of effluent per day.
The treated effluent will be passed into a polymer lined evaporative transpiration leach field. The lining
will minimise potential seepage into the groundwater system and therefore ensure the Priority 1
drinking water source remains of high quality. The whole system is completely sealed from the toilet, to
the septic tank, to the leach field; though for precautionary purposes regular inspections will be
undertaken for any leaks or maintenance requirements. More information is provided in the Mining
Proposal (support information Plan 8 and section 4.7).
* If there is likely to be discharges to a watercourse or marine environment, has any
analysis been done to demonstrate that the State Water Quality Management
Strategy or other appropriate standards will be able to be met?
