Remediation work stalled
A DECISION has been made on remediating the site of an antimony processing plant adjacent to Hillside Dr in Urunga but work has been delayed.
A long-standing problem for the community, the site has been leaching heavy metals, including mercury, into wetland since the early 1970s.
Remediation work was due to start in August but this looks unlikely.
A Remedial Action Plan commissioned by the Soil Conservation Service was published earlier this year and offered several clean-up strategies.
Options for soil and water remediation included off-site treatment, on-site remediation and in-situ containment.
The community favoured off-site treatment but the Department of Crown Lands NSW adopted the major recommendation of the RAP, in-situ containment, a cheaper option.
A Crown Lands NSW spokesman said work was expected to begin sometime in September.
"We are waiting for the Department of Planning to approve the Environmental Impact Statement and for the final tick from the Environmental Protection Authority," he said.
Contaminated soil would be moved from the wetland and sealed in a permeable clay lined structure for further monitoring.
The clean-up has a budget of $4 million and is due to be complete by Christmas.
