Sedgman Consulting was engaged by Queensland Nickel to undertake an environmental and engineering baseline assessment within EPC 1029, located in the Styx Basin Central Queensland.

The baseline assessment was undertaken to identify the existing environmental values and constraints; provide information to enable the regulatory bodies to determine the approvals process and support pre-lodgement discussions; and identify the engineering infrastructure and requirements for the mine.

An environmental assessment program was initiated to begin gathering data and describing the environment in this little-studied part of the Central Queensland coastal region. The baseline program was developed, managed and delivered as a baseline report to the client within the specified timeframes, not-withstanding inclement weather and regional flooding at the start of the project. Follow up studies were then initiated based on identified data gaps and long lead time components.

The environmental studies managed and undertaken included:
• Terrestrial flora and fauna assessments over the 350 km2 EPC
• Aquatic ecology – freshwater, marine and estuarine habitats
• Groundwater investigation, bore census and assessment
• Water quality – 12 month receiving waters monitoring program
• Noise and air preliminary assessments and noise monitoring
• Contaminated land
• Climate, climate change and greenhouse gases
• Land resources, including soils, good quality agricultural land and strategic cropping land
• Surface water quality, hydrology, hydraulic and flooding assessment
• Transport and mining infrastructure assessment.

We were then commissioned to manage the approvals pathway for the level 1 mining lease project including undertaking further detailed investigations and preparation of an Environmental Management Plan to support the application. Detailed investigations included hydrogeological/groundwater assessment; water resources assessment; surface water quality assessment; terrestrial, freshwater, estuarine and marine ecology studies; contaminated land assessment; land suitability assessment; and mine remediation and rehabilitation.

Project management and implementation of the Styx Coal Project was controlled by Sedgman Consulting, including field work programs, sub-consultant management/technical review and client liaison adapting the program to meet client requirements and expectations as the project developed. Works were completed within budget and on time with finalisation of the EM Plan and application documentation for submission.
