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.

environment includes (but is not limited to):
A watercourse;
Groundwater; and
An area of land that is not specified in Schedule A – Table A1 (Authorised Mining Activities and
Locations).
‘Receiving waters’ means the waters into which an environmental authority authorises releases of
mine affected water.
‘Rehabilitation’ the process of reshaping and revegetating land to restore it to a stable landform
and in accordance with the acceptance criteria set out in an environmental authority and, where
relevant, includes remediation of contaminated land.
Bauxite Hills Project Draft EA Conditions
20-31
‘Release event’ means a surface water discharge from mine affected water storages or
contaminated areas on the licensed place.
‘Reference’ means a sample set which covers the variance in monitoring or other data either due to
natural changes or operational phases of the mining activities.
‘Residual void’ means an open pit resulting from the removal of ore and/or waste rock which will
remain following the cessation of all mining activities and completion of rehabilitation processes.
‘Revegetation’ is the re-establishment of vegetation of a species and density of cover similar to
surrounding undisturbed areas or the landform that existed before mining activities on soil surfaces
associated with the construction or rehabilitation of a watercourse diversion.
‘RL’ means reduced level, relative to mean sea level as distinct from depths to water.
‘Self-sustaining’ means not requiring on-going intervention and maintenance to maintain
functional riverine processes and characteristics
‘Sensitive place’ means:
A dwelling, residential allotment, mobile home or caravan park, residential marina or other
residential premises; or
A motel, hotel or hostel; or
An educational institution; or
A medical centre or hospital; or
A protected area under the Nature Conservation Act 1992, the Marine Parks Act 1992 or a World
Heritage Area; or
A public park or gardens.
Note: The definition of ‘sensitive place’ and ‘commercial place’ is based on Schedule 1 of EPP Noise.
That is, a sensitive place is inside or outside on a dwelling, library and educational institution, childcare
or kindergarten, school or playground, hospital, surgery or other medical institution, commercial and
retail activity, protected area or an area identified under a conservation plan under Nature
Conservation Act 1992 as a critical habitat or an area of major interest, marine park under Marine
Parks Act 2004, park or garden that is outside of the mining lease and open to the public for the use
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.
Bauxite Hills Project Draft EA Conditions
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.
‘Significant residual impact’ has the meaning in section 8 Environmental Offsets Act 2014.
‘Stable’ means geotechnical stability of the rehabilitated landform where instability related to the
excessive settlement and subsidence caused by consolidation/settlement of the wastes deposited,
and sliding/slumping instability has ceased.
‘Strategic environmental areas’ has the meaning in section 11(1) of the Regional Planning Interest
Act 2014.
‘Suitably qualified and experienced person’ means a person who is a Registered Professional
Engineer of Queensland under the provisions of the Professional Engineers Act 2002, who has an
appropriate level of expertise in the structures, geomechanics, hydrology, hydraulics and
environmental impact of watercourse diversions.
An appropriate level of expertise includes:

- Investigation, design or construction of watercourses diversions;
- Operation and maintenance of watercourse diversions;
- Geomechanics with particular emphasis on channel equilibrium, geology and
geochemistry;
- Hydrology with particular reference to flooding, estimation of extreme storms, water
management or meteorology;
- Hydraulics with particular reference to sediment transport and deposition and erosion
control;
- Hydrogeology with particular reference to seepage and groundwater;
- Solute transport processes and monitoring thereof, or
Sufficient knowledge and experience to certify that where the suitably qualified and
experienced person has relied on advice and information provided by other persons with
relevant expertise*:
- They consider it reasonable to rely on that advice and information; and
- The expert providing the advice and information has knowledge, competency, suitable
experience and demonstrated expertise in the matters related to watercourse diversions.
* Persons with relevant expertise include:
Geomorphologist: person who has demonstrated competency and relevant experience in
stream geomorphology and watercourse diversions;
Geotechnical Expert: person who has demonstrated competency and relevant experience in
geotechnical assessment of soil characteristics suitable for watercourse diversions;
Bauxite Hills Project Draft EA Conditions

Vegetation Expert: person who has demonstrated competency and relevant experience in the
identification, role and function of vegetation with watercourses and adjoining floodplains, and
has demonstrated competency and relevant experience in revegetation of watercourse
diversions and adjoining floodplains;
Groundwater Expert: person who has demonstrated competency and relevant experience in
groundwater systems;
Surface Water Expert: person who has demonstrated competency and relevant experience in
hydrology;
Engineer: person who is a Registered Professional Engineer of Queensland (RPEQ) under the
provisions of the Professional Persons Act 2002 or has similar qualifications under a respected
professional registration association, and has demonstrated competency and relevant
experience in design and construction of watercourse diversions; and
Soils Expert: person who has demonstrated competency and relevant experience in soil
classification including the physical, chemical and hydrologic analysis of soil.
‘the Act’ means the EP Act.
‘μS/cm’ means micro Siemens per centimetre.
‘Water’ is defined under Schedule 4 of the Water Act 2000.
‘Watercourse’ has the same meaning given in the Water Act 2000.
‘Water quality’ means the chemical, physical and biological condition of water.
‘Waters’ includes river, stream, lake, lagoon, pond, swamp, wetland, unconfined surface water,
unconfined natural or artificial watercourse, bed and bank of any waters, dams, non-tidal or tidal
waters (including the sea), storm water channel, storm water drain, and groundwater and any part
thereof.
‘80th percentile’ means that not more than two of the measured values of the quality characteristic
are to exceed the stated release limits for any ten consecutive samples.
