Environmental Impact Statement
About this document
BHP Billiton Mitsubishi Alliance (BMA)
has produced a draft Environmental Impact Statement
(EIS) detailing the baseline environmental studies, potential
impacts and management strategies for the Daunia Coal
Mine Project. This Community Overview document does
not form part of the formal government requirements for

BHP Billiton Mitsubishi
Alliance (BMA) was formed
in 2001 as a partnership
between BHP Billiton and
Pty Ltd under which the
two companies share equal
ownership and management
of seven Bowen Basin
coal mines – Blackwater,
Riverside, Peak Downs, Saraji,
Norwich Park and Gregory
Crinum as well as the Hay
Point coal export terminal
In addition, BMA manages
the operations of BHP Mitsui
Coal, which is owned by BHP
Billiton (80 per cent) and
Mitsui and Co (20 per cent).
These operations include the
South Walker Creek Mine
and Poitrel Mine. In total,
BMA has the capacity within
its current mining leases in
the Bowen Basin to produce
approximately 58 million
tonnes per annum (Mt/a) of
coal. BMA employs around
10,000 people (including
contractors) and is the largest
employer in the Central
Queensland region. Currently,
over 4,000 people are
In 2008, BMA announced the
BMA Bowen Basin Coal Growth
Project which involves the
expansion and development
of BMA’s coal mining
operations in the northern
section of the Bowen Basin,
near Moranbah, Queensland.
The Growth Project involves
the production of up to an
additional 21 Mt/a of coal
products through the proposed
development of two new coal
mining operations: the Daunia
Mine and Caval Ridge Mine
(including the expansion of
Peak Downs Mine); and the
expansion of the Goonyella
Riverside Mine. BMA is also

measures will need to be taken in year 20 of operations
as blasting activity will be about 1.5 kilometres from
Olive Downs. Vibration levels at all three residences are
estimated to be within the recommended 5 mm/s.
How will noise impacts be minimised?
Noise levels at Daunia Station and Mavis Downs are
predicted to be within the night time criteria of 28
dB(A). The following mitigation measures will further
reduce noise impacts:
• Developing maintenance and operations
procedures to minimise nuisance noise from
• Positioning noisy equipment away from sensitive
• Containing noisy equipment within pits.
• Applying noise mitigation technology on
• Implementing noise monitoring programs at
• Implementing a noise complaints investigation
BMA will continue to work with the Olive Downs
property owners during the development and operation
of the Daunia Coal Mine Project to respond to noise and
vibration issues. Additional ‘at receiver’ noise mitigation
options may need to be considered.
How will vibration and airblast pressure
impacts be reduced?
Blasting times will be limited to 9am to 5pm, with no
blasting to be carried out at night time. A number of

technical adjustments can be made to reduce blast size

What types of waste will be generated?
During construction, waste types include cleared

on revegetated areas or as ﬁll on site. Other expected
construction waste products include concrete, metal

minimised by purchasing only the amount required.
During both construction and operations, licenced
waste contractors will manage removal of grease traps,
waste oil, oily water, oily rags, paints and resins, vehicle
batteries and tyres from the site. General waste from
workshop and ofﬁce environments will be disposed of
at the Moranbah landﬁll.
How will regulated waste be managed?

This section outlines the cumulative
impacts of the Daunia Coal Mine Project on local and
regional communities and the environment.
What are cumulative impacts?
There are two scales of cumulative impacts of the
Daunia Coal Mine Project – localised and regional.
Localised impacts include the cumulative effects of
operations which are close enough to potentially
cause quantiﬁable additive effects to issues such
as dust, the generation of noise and vibration and
groundwater drawdown. In this case, localised
impacts are considered from the combined
operations of the Poitrel Mine, Millennium Mine and
Regional cumulative impacts include the Daunia
Coal Mine Project’s contribution to impacts caused
by mining operations throughout the Bowen Basin.
While individual projects may not represent a
substantial impact, the cumulative impact on issues
such as habitat loss, water quality degradation
and socio-economic impacts may be sufﬁcient to
What about future impacts?
The impacts of the Daunia Coal Mine Project were
also considered in the context of the BMA Bowen
Basin Coal Growth Project. This Project is the ﬁrst
of four elements including the Caval Ridge Mine,
Goonyella Riverside Mine Expansion and
Moranbah Airport. These other elements lie at least
20 kilometres to the north of the Daunia Coal
Mine Project and therefore will not have any
What are the cumulative impacts?
Land Resources: The Daunia Coal Mine Project
will result in the loss of approximately 240ha of
Class A and B Good Quality Agricultural Land which
represents approximately 0.02 percent of this land

within the Isaac Regional Council.
Surface Water Resources: The mining area covers
approximately 2,600 hectares which represents
approximately 0.1 per cent of the total catchment
area of the Isaac River. The Daunia Coal Mine
Project is not expected to have a signiﬁcant
regional cumulative impact on surface water ﬂows.
Operational water requirements will be minimised
by collecting, managing and reusing water on site.
