20 Draft EA Conditions

This chapter sets out the substantive obligations which Metro Mining envisages may be contained

within the Project’s draft Environmental Authority (EA). The presentation of the following EA

conditions is intended to assist with the process of developing appropriate EA conditions for the

Project in consultation with the Department of Environment and Heritage Protection (EHP). This

chapter does not attempt to replace or replicate the Notice of Decision stage of the EA application

process under Chapter 5, Division 3, subdivision 2 of the Environmental Protection Act 1994 (EP Act).

EHP determines an application for a mining project EA in accordance with the requirements of the

EP Act with consideration to its Regulatory Strategy and model mining conditions (EM944),

respectively.

The Regulatory Strategy provides for EHP’s operational delivery. This established the onus of

environmental management and compliance on mining EA permit holders, with EHP focussing

largely on compliance monitoring backed up by appropriate enforcement or stopping activities

where compliance is not met.

The Model Mining Conditions and Model Conditions for Structures provide a basis for proposing

environmental protection commitments in EA application documents. The Model Mining Conditions

guideline acknowledges that assessment and conditioning must be based on the specific

circumstances for each project. The guideline allows for modification of the Model Mining

Conditions to tailor for site-specific conditions and project circumstances.

The proposed conditions presented within this chapter have been derived to address the

anticipated impacts of the Project and are developed to be measurable and auditable. Where

alterations or alternative conditioning, from the Model Mining Conditions has been proposed to

account for Project specific circumstances, an explanatory box has been provided beneath the

condition. The box explains the change and provides reasoning for the alteration. For ease of

application and review the proposed EA conditions have been structured as per the EM994 and

EM634 guidelines.

This draft EA is relevant only for mining activities undertaken outside of the Skardon River Bauxite

Project (SRBP) Mine Infrastructure Area (MIA), the Barge Loading Facility (BLF) and the

accommodation facility areas including the Sewerage Treatment Plant (STP), irrigation area and

biosolids sludge management area as the activities within these areas will be undertaken in

accordance with the EA conditions pertaining to the SRBP. Barging and transhipment activities

undertaken by Metro Mining will be undertaken pursuant to the EA conditions issued specifically

for this Project.

20.1 Project Overview

The following provides a summary of the Project, incorporating Gulf Alumina’s existing and

approved infrastructure. A more detailed description of the modified Project is provided in Section

4 of the Supplementary Report.

Aldoga, a 100% owned subsidiary of Metro Mining, proposes to develop the Project located on a

greenfield site on the western coastline of Cape York, Queensland, approximately 35 km northeast

of Mapoon (see Error! Reference source not found.). The Project will include an open cut

operation characterised by several shallow open cut pits; BH6 east, BH6 west and BH1; and haul

Bauxite Hills Project Draft EA Conditions

20-5

roads linking BH1 to BH6 east and BH6 east and BH6 west to the existing SRBP haul road. The

Project will utilise infrastructure at the approved SRBP for stockpiling and barge loading operations.

Run-of-mine (ROM) and/or product bauxite will be taken to the SRBP MIA and BLF for screening

and loading of product bauxite on to barges for transport to the offshore transhipment area and

then loaded onto awaiting Ocean Going Vessels (OGV). The Bauxite Hills Project will produce and

transport up to 5 Mtpa of ore over approximately 12 years. The mine will not be operational during

the wet season.

Bauxite from the Project is suitable as a Direct Shipping Ore (DSO) product (i.e. ore is extracted and

loaded directly to ships with no washing or tailings dams required). Bauxite will be screened in-pit

and/or at the MIA, and then hauled to the product stockpile using road train trucks. Bauxite will be

transported by barge via the Skardon River to the transhipment site, approximately 12 km offshore,

and loaded into ocean going vessels (OGVs) and shipped to customers. No dredging or bed-levelling

for transhipping is proposed as part of this Project as bed-levelling impacts have been assessed as

part of the SRBP and the separate Sustainable Planning Act 2009 (SP Act) approval for these works

have been commenced by Gulf Alumina

OGVs of between 50,000 to 120,000 tonne (t) each will be loaded at the transhipment anchorage

site. Vessels will be loaded and bauxite will be transported to OGVs 24 hours per day with barges

having an initial capacity of approximately 3,000 t to meet early production volumes, increasing up

to 7,000 t as the Project reaches a maximum production volume of 5 Mtpa.

The construction of the Bauxite Hills Project is due to commence in July 2017 and is expected to take

three months to complete. Construction of infrastructure for the SRBP is likely to commence early

in 2017 under the conditions of the existing approval for the SRBP. The first shipment of bauxite is

planned for late 2017. The Project will be 100% fly-in fly-out (FIFO) due to its remote location. The

Project will operate over two 12 hour shifts per day for approximately eight months of the year and

is expected to employ up to 254 employees during peak operations. In addition to the workforce, it

is expected that the Project will result in the employment of additional workers through local and

regional businesses servicing the accommodation camp and the construction and operation of the

mine.

other than for sport or organised entertainment. A commercial place is inside or outside a commercial

or retail activity.

A mining camp (i.e., accommodation and ancillary facilities for mine employees or contractors or both,

associated with the mine the subject of the environmental authority) is not a sensitive place for that

mine or mining project, whether or not the mining camp is located within a mining tenement that is

part of the mining project the subject of the environmental authority. For example, the mining camp

might be located on neighbouring land owned or leased by the same company as one of the holders of

the environmental authority for the mining project, or a related company. Accommodation for mine

employees or contractors is a sensitive place if the land is held by a mining company or related

company, and if occupation is restricted to the employees, contractors and their families for the

particular mine or mines which are held by the same company or a related company.


20-32

For example, a township (occupied by the mine employees, contractors and their families for multiple

mines that are held by different companies) would be a sensitive place, even if part or all of the

township is constructed on land owned by one or more of the companies.
