DZP Field Assessment 1
Dubbo Zirconia Project Field Assessment

 

Client: Alkane Resources

Area: Toongi, Dubbo Regional LGA

Approval Type: State Significant Development

Years:  2012-on-going

 

The Dubbo Zirconia Project (DZP) comprises the development, mining and processing of zirconium, niobium and rare earth element resources located near Toongi, approximately 25km south of the town of Dubbo.

OzArk EHM carried out both archaeological and ecological impact assessment for a 2,500 ha study area, with an 800 ha impact footprint. This information was used for the Environmental Impact Statement required for development approval.

The heritage fieldwork component included surface survey and test-excavation, and required 90 person days. Representatives from the Registered Aboriginal Parties attended the fieldwork. 52 sites were identified in the study area, 33 of which were newly recorded.

OzArk was involved with all aspects of assessing the scientific values, from field work through to numerous meetings with Aboriginal stakeholders, the project team and government regulators. OzArk was able to provide a detailed set of recommendations for this large study area that met the requirements of the government regulators and the approval of both the proponent and the Registered Aboriginal Parties.

One finding from the initial ecological fieldwork was the presence of the threatened species “Pink-tailed Worm-lizard” Aprasia parapulchella . OzArk has now designed and implemented an on-going monitoring plan for the Pink-tailed Worm-lizard prior to the construction and operation of the mine. This will allow translocation to occur for specimens found within the mine impact zone. Annual monitoring occurs after appropriate weather conditions are present.

In-conjunction with the Pink-tailed Worm-lizard monitoring, OzArk has begun monitoring the vegetation in the same sites to determine any association with vegetation structure and presence/absence of the species.

OzArk continues to work closely with the client to determine the best monitoring options available to meet approval requirements.

Bulga Optimisation Project Creek Survey

Client: Glencore Pty Ltd

Area: Upper Hunter Valley

Approval Type: State Significant Development

Years: 2011-2012

 

The Bulga Optimisation Project is a proposed expansion of the Bulga coal mine, along with related infrastructure construction such as a noise and visual bunds and road works.

OzArk EHM completed the survey and test excavation required to assess the scientific values present within a 4,873 ha area proposed for impact by the Bulga Optimisation Project.

This project involved over 343 person days to complete the survey and a further two weeks of test excavation, including the excavation of nearly 200 test pits.

OzArk EHM was involved with all aspects of assessing the scientific values of the study area from field work through to working with a large number of Aboriginal stakeholders both in the field as well as at meetings and site visits. This project demonstrates OzArk EHM’s ability to work with a large number of Aboriginal stakeholders and to coordinate the field assessment of a project covering a large and diverse topographic area.

Client: Roads and Maritime Services

Area: Border Rivers/Gwydir

Approval Type: Part 5: Infrastructure

Year: 2013

 

Roads and Maritime Services proposed to demolish two bridges on the border of NSW and QLD as they have been replaced by new concrete bridges.

OzArk prepared a Review of Environmental Factors, which assessed the historic and ecological values of the two bridges. The assessment targeted protected matters under the NSW Threatened Species Conservation Act 1995 as well as the Queensland equivalent legislation Nature Conservation Act 1992 and the Commonwealth Environment Protection and Biodiversity Act 1999.Both bridges were also present on the RMS s170 Heritage register under the Heritage Act 1977 (NSW).

Two reports were written for each of the two bridges (four reports total). One report for the NSW authority and one for the QLD authority for each bridge.

OzArk then undertook an archival recording for both bridges before their demolition. Copies were provided to both State and Local Governments in the two states.
