The Environment Protection Authority (EPA) has concluded its assessment of a proposal by Gadtech Materials Pty Ltd for the Sunshine Quarry, at Mining Lease 2065P/M, Sunshine Road, Maydena in the Derwent Valley municipality.
The proposal is for the establishment and operation of a sandstone quarry and materials handling activity (crushing and screening), at mining lease 2065P/M, which is located approximately 6 kilometres north west of the township of Maydena on land managed by Sustainable Timber Tasmania and private freehold land. The quarry is proposing to extract and process up to 90,000 cubic metres of rock per annum. Blasting will be undertaken at the quarry approximately 3 – 4 times per year.
EPA Tasmania Deputy Director, Cindy Ong, who made the determination under delegation from the EPA Board, concluded the proposed development can be managed in an environmentally sustainable and acceptable manner, with certain conditions. The Board requires these conditions to be included in any permit subsequently granted by Derwent Valley Council.
“Various environmental issues were considered by the Board in its assessment, particularly the potential for impacts on natural values and on nearby geoconservation areas, potential impacts on waterways, and impacts of noise and dust from quarrying operations and drilling and blasting” Ms Ong said.
In relation to natural values, specific conditions have been imposed requiring pre-clearance surveys for Tasmanian devil and Spotted-tailed quoll presence or habitat, as well as conditions requiring works to cease should nests or nesting trees of the Wedge-tailed eagle, Grey Goshawk, or Masked owl be detected on site.
Specific limits have been placed on blasting at the quarry to ensure that nearby geoconservation areas are not impacted by ground vibration, and to ensure residents are not impacted by blasting noise and vibration. The operating hours of the quarry are also restricted.
Standard quarry operating conditions have been imposed for management of dust and water from the quarry, to ensure that impacts beyond the boundary of the mining lease do not occur.
No public representations were received in relation to the permit application during the formal public consultation period, which was open for 28 days from 13 March 2021.
The proposal was considered by the Deputy Director in the context of the sustainable development objectives of the Resource Management and Planning System of Tasmania (RMPS), and in the context of the objectives of the Environmental Management and Pollution Control System (EMPCS) established by the EMPC Act.
The functions of the EPA are to administer and enforce the provisions of the EMPC Act, to further the RMPS and EMPCS objectives and, in particular, to use its best endeavours to protect the environment of Tasmania.
The Deputy Director undertook the assessment of the proposal in accordance with the Environmental Impact Assessment Principles defined in Section 74 of the Act.
The environmental assessment report, including the environmental conditions, has been issued to Gadtech Materials Pty Ltd, and the Derwent Valley Council.
