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
Environmental Protection Act 1994 (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.
20.1 Project Overview
Aldoga Minerals Pty Ltd (Aldoga), a 100% owned subsidiary of Metro Mining Limited (Metro
Mining), proposes to develop the Project located on a greenfield site on the western coastline of
Cape York, Queensland, approximately 35 kilometres (km) northeast of Mapoon. The Project will
include an open cut operation, haul roads, Barge Loading Facility (BLF), Roll on/Roll off (RoRo)
facility, transhipping and will produce and transport up to 5 million tonnes per annum (Mtpa) of ore
over approximately 12 years. The mine will not be operational during the wet season.
The Project is characterised by several shallow open cut pits that will be connected via internal haul
roads. The internal haul roads will be connected to a main north-south haul road that will link with
the Mine Infrastructure Area (MIA), BLF and RoRo facility located to the north of the pits on the
Skardon River. Bauxite will be screened in-pit and then hauled to the product stockpile using road
train trucks.
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 transported by
barge via the Skardon River to the transhipment site, approximately 12 km offshore, and loaded into
Bauxite Hills Project Draft EA Conditions
20-2
ocean going vessels (OGVs) and shipped to customers. No dredging or bed-levelling for transhipping
is proposed as part of this Project.
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 mine is due to commence in April 2017 and is expected to take seven months
to complete. The first shipment of bauxite is planned for October 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.

administering authority may request the holder of this environmental authority to take appropriate
action to mitigate the nuisance and the holder must take appropriate action (e.g. by screening or
directing the light away from the sensitive place) within a time set by the administering authority.

Exceedance Investigation
(E4) If quality characteristics of groundwater from compliance bores identified in Table 20-5 exceed
any of the trigger levels stated, the holder of this environmental authority must complete an
investigation in accordance with the ANZECC and ARMCANZ 2000.
Bore construction and maintenance and decommissioning.
(E5) The construction, maintenance and management of groundwater bores (including
groundwater monitoring bores) must be undertaken in a manner that prevents or minimizes
impacts to the environment and ensures the integrity of the bores to obtain accurate monitoring.
20.2.9 Schedule F – Water
Contaminant Release
(F1) Contaminants that will, or have the potential to cause environmental harm must not be
released directly or indirectly to any waters as a result of the authorised mining activities, except as
permitted under the conditions of this environmental authority.
Receiving waters and water quality parameters
(F2) Receiving waters affected by the release of water from storm water contaminated by the
mining activities (bauxite mining) must be monitored at the locations and frequencies defined in
Table 20-7 and Table 20-8 and shown at Figure 20-3 and comply with the interim contaminant
trigger limits defined in Table 20-9 and Table 20-10 for marine / estuarine waters, respectively.
Note that the interim trigger values will be progressively updated prior to construction and
operation as additional water quality data are collected during monitoring events.
Metro mining does not propose to release waters to freshwater or wetland receiving waters. As such
no release point monitoring locations are nominated. A release point is proposed at the MIA that
will release waters to estuarine receiving water. A release point monitoring location is nominated
in Table 20-8.
Note: Preliminary WQOs are provided in Table 20-6 and are based AWQG – 99% trigger values, AWQG – aquaculture
and model mining conditions and site data where no published trigger values are available. Additional and ongoing
sampling will be undertaken to derive site specific local WQOs for the 20th, 50th and 80th percentiles.
