Macquarie Water Pipeline 1
Macquarie Water Pipeline Test Excavation

Client: Orange City Council

Area: Macquarie River to Orange

Approval Type: Part 3A Development

Years: 2012-2013

The Macquarie Water Pipeline Project includes the construction of a 39km-long water pipeline from the Macquarie River to Suma Park Reservoir in Orange, as well as associated infrastructure.

OzArk EHM accepted this project following initial assessment by another consultant. OzArk developed a Cultural Heritage Management Plan (CHMP) based on the results of previous investigation, undertook test excavations and other further investigation. This required further consultation with Registered Aboriginal Parties to refine the CHMP for the construction and operation of the pipeline.

The OzArk directed component of the heritage saw 55 person days to undertake test excavation and further investigation at 20 sites and five areas of archaeological sensitivity. The fieldwork program was achieved in one week, in which 62 test pits were excavated and over 3.5km of archaeologically sensitive areas was investigated.

OzArk demonstrated an ability to inherit a Macquarie Water Pipeline 2project with a complex history and successfully work with the Aboriginal stakeholders, the project team and government regulators. OzArk also managed to execute a fieldwork program with numerous logistical and safety considerations within a tight timeframe.

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.

Dubbo Zirconia Project Test Excavation

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.

Bulga Optimisation Archaeological Survey

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.
