Environmental Impact Assessment for Caval Ridge Coal Mine Project

Environmental Impact Assessment 1
Introduction
This project involves the development of a multi-seam open cut mine, which will be
carried out at Caval Ridge. The project will be carried out by BHP Billiton Mitsubishi Alliance
Coal Operation Pty Ltd (BMA) and will include new coal handling and processing infrastructure.
Also, the project will utilize types of machinery such as draglines and truck-shovel fleet. BMA
will be the primary project management team and will do that on behalf of the client who is
Central Queensland Coal Associates Joint Venture (QCQA), which is a partnership between
BHP Billiton and Mitsubishi Corp (BM Alliance Coal Operations Pty. Ltd., & RPS (Firm).
1900). This project will involve the construction of open cut coal mine, the railing of the coal to
terminals; spoil dump construction and construction of water management system. Additionally,
the project will involve haul road construction, construction of power supply, rail spur
construction and construction of mine industrial area. All these services will be connected to the
mining and exportation of the coal.
This project is also related to Bowen Basin Coal Growth project, Daunia Mine,
Goonyella Riverside mine Expansion, Moranbah Airport, Phased EIS Process among others.
Different EIS studies have been taken in relation to the available regulations and approvals in
QC. The project looks to enhance the EIS proponents. The EIS also focuses on informing
decision makers and other parties about potential environmental issues due to the project (Rocky
Mountain Mineral Law Foundation, 2013). In the process, EIS focuses on public views in the
planning process. Other general sections of the project include the social monitoring and
community consultation. Lastly, the project has acquired the relevant approvals from the proper
authorities.

Project justification and sustainability
Queensland is one of the significant sources of coal in Australia and makes the country a
leading exporter. Coal is a significant exporter and contributor to the country’s GDP. In
addition, the project will be able to produce high-quality coal, which is in high demand. Job
creation is estimated to rise due to this project creating close to 70,000 jobs indirectly and 20,000
directly. Technological advancement in this project can reduce the risks associated with the
mining (Queensland & Queensland, 2014). Additionally, the BMA project is compatible with the
regulations which are outlined in section 1.6. Furthermore, the EIS section can show the
numerous benefits which the project is able to offer. These include critical benefits in an
economic sense, social and environmental. Also, these sections highlight important costs which
are experienced in these sections. In addition, the project can provide critical socio-economical
benefits and address the socio-economical issues arising. In economical perspective, the project
will add value to the other industries in this location from the current $479 to $599 million.
Social class for the residents will rise due to jobs in the area.
The mine resource is allocated near an existing peak Downs Mining Lease (ML 1775),
and it is included in the long-term development goals. Different studies have been carried to
project on the sustainability of the current structure and economic evaluation of this project. This
project will not have any impact on the existing projects on coal, gal, and minerals in the area.
The project does not have any alternative option, and the country is likely to lose a lot if not
implemented. Several mining methods will be performed such as dragline, electric rope shovel,
and truck and hydraulic excavators.
Air quality

Environmental Impact Assessment 3
Mining activities have adverse effects on quality of air within the mining areas. In this
assessment for the Caval Ridge project, the dust from the site was considered as a risk due to the
mining and movement activities of the vessels in the mine (BHP Billiton Mitsubishi Alliance &
RPS (Firm)., 2011). In this area, an evaluation of the source of dust emission and mitigation
measures is evaluated. They are analyzed to determine the potential impact to the communities
residing in the area. Additionally, the quality of air has a significant impact on area climate and
environmental status. In the assessment, the meteorological department is highly involved since
it plays a key role in transportation and dispersion of dust from the mining site. In the dispersion
of the dust, a key model such as DERM, which is approved by the Calmet/Calpuff modeling
packages will be used. In addition, air quality will be maintained according to key standards and
legislation available. Control and keeping the climate according to the current climatic condition
described in Section 4.1 of EIS will be prioritized.
On the legislative framework, the project will be carried according to the Queensland and
Australia laws. The guidelines on the Environmental Protection for Air policy developed in 2008
will be a key guideline in this project. In addition, the dust deposition guidelines will be adopted
through the use of DERM protection (Giant Mine Remediation Project , & Canada, 2015). The
control of the dust will be done to prevent any production of dust to levels considered to be a
nuisance. The quality of the pollutants in the air will be measured before they are released from
the site.
In the air quality management, it is crucial to look at the potential impacts and key
mitigation measures which will maintain high-quality air within the mine area. In this project, the
air quality impact was assessed through estimation of the emissions from any mining-related
activities and mining itself. Dispersion models were used to estimate the potential effects and
