Amendment description

On 18 January 2018, the Licence Holder submitted an application (Application, 2018) to DWER for an amendment to the Gruyere Gold Project (Premises) Licence L9000/2016/1 to include category 12.

The Licence Holder is proposing to intermittently utilise a mobile crushing and screening plant (the Plant) to produce aggregate for haul roads, laydown yards and compounds on an as needs basis. The Plant will be located at borrow pits and at the proposed Tailings Storage Facility (TSF) (assessed under works approval W6002/2016/1) within the Premises. The Plant has a processing ability of 90-200 tonnes per hour, a feeding size of 480-750 mm and will produce an outlet size of 65-200 mm.

As there will be minimal construction and commissioning activities associated with the installation of the Plant at the Premises, as such the Delegated Officer has determined that the inclusion of category 12 can be done as an amendment to the Licence via this Amendment Notice.

Table 2 below outlines the proposed changes to the Licence.

Location and receptors

The Premises is located approximately 200 km north-east of Laverton in Western Australia. There are no relevant sensitive land uses in the vicinity of the prescribed premises with the Cosmo Newbery Aboriginal Community located approximately 80 km north-west of the Premises.

The workforce is accommodated on the Premises, but as this accommodation is operated by the Licence Holder, it is not considered a sensitive land use or receptor.


Table 5 below lists the relevant environmental receptors in the vicinity of the prescribed premises which may be receptors relevant to the proposed amendment.

Risk assessment

Table 6 below describes the Risk Events associated with the amendment consistent with the Guidance Statement: Risk Assessments. The table identifies whether the emissions present a material risk to public health or the environment, requiring regulatory controls.

The closest sensitive receptor is Cosmo Newbery Aboriginal Community located approximately 80 km from the Premises

Air / wind dispersion

Health and amenity impacts

Slight Rare Low

The Delegated Officer considers the distance to the nearest sensitive receptor sufficient to ensure that there are minimal impacts to health and amenity on a local scale

Noise associated with crushing and screening activities

Amenity impacts

Slight Rare Low

Stormwater runoff from the Plant area

Yeo Lake Nature Reserve approximately 12 km from the Plant

Soil and surface water drainage

Stormwater runoff

Soil contamination inhibiting vegetation growth and survival

Slight Rare Low The Plant will be located within the TSF footprint

The TSF has a 2-3 m in depth diversion drain that runs along the eastern edge of the TSF

Stormwater will be diverted to this diversion drain (Gruyere JV, 2018)

There are no watercourses in the vicinity of the Plant and the Yeo Lake Nature Reserve is 12 km away

Based on the above, the impact from stormwater runoff would result in minimal on-site impacts


Decision

The Delegated Officer has determined that the key emissions associated with the operation of the Plant to be dust, noise and stormwater runoff. The Delegated Officer considers the risk associated with these emissions to be low.

The Delegated Officer has determined that an amendment be made to the Licence to allow for the inclusion of category 12 with a design capacity of 1,752,000 tonnes per Annual Period.

Other amendments

During this amendment the following administrative changes have also been made to the Licence:
