The Environment Protection Authority (EPA) has concluded its assessment of a proposal by Gadtech Materials Pty Ltd for upgrades to the existing level 2 quarry located at Nichols Road in Nubeena in Tasman Council municipality. The proposal was referred to the Board in January 2020.
The proposal involves changes to the operating hours, the addition of crushing and mechanised / vibratory screening, and approval of an updated Blast Management Plan that allows blasting to take place without having to seek approval from the Director, EPA and Director of Mines prior to each blast taking place. The regulatory limit for extraction and processing remains unchanged at 10,000 cubic meters per year.
The Chair of the EPA Board, Warren Jones, said that the 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 Tasman Council.
“Various environmental issues were considered by the Board in its assessment, particularly noise and air emissions" Mr Jones said.
“Noise emissions will be managed through a suite of conditions which set noise limits, including for air blast overpressure and ground vibration during blasting. In addition, monitoring is required for each blast and a noise survey must be undertaken once crushing and vibratory screening is in place at the quarry to ensure the limits are being met." Mr Jones said.
“Air emissions will be managed through a standard suite of conditions, requiring dust to be controlled to prevent environmental nuisance including, covering or dampening of loads prior to leaving the land and appropriate dust supression measures on the crushing and screening plant." Mr Jones said.
Three (3) representations were received in relation to the permit application. The environmental issues raised in these representations were noise and air emissions. Public consultation was open for a 28 day period from 13 June 2020.
The proposal was considered by the Board 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
Environmental Management and Pollution Control Act 1994 (the EMPC Act).
The functions of the Board 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 Board undertook the assessment of the proposal in accordance with the Environmental Impact Assessment Principles defined in Section 74 of the Act.
The Board's environmental assessment report, including the environmental conditions, has been issued to the proponent and Tasman Council.
