Funded by the Minister for Communications, Climate Action and Environment, the priority health and safety works implemented the most urgent recommendations contained in the Feasibility Study and Management Plan prepared for the site by CDM Smith in 2008.
The works were delivered on a phased basis and involved a range of works including the remediation of the Tigroney spoils area that stands at the base of the East Avoca mining area. The area had served different purposes during the various stages of mine workings and the site was covered by spoil material, to an estimated average depth of 2m. This close proximity of the Tigroney Spoils to the Avoca River with their high acid-generating potential resulted in acidic surface water runoff and infiltration with high metals contents which is a direct contributor to the reduced water quality in the river.
Remediation works began in 2016 to regrade and cap the spoils area, constructing surface drains to divert the surface flow around or across the capped area into the river and vegetating the capped surface with grass and heather. In addition to these works on a complex and challenging site, a number of important actions were undertaken to preserve mining heritage features on the site, notably the complete rehabilitation of a pair of ore bins on the site and the reconstruction of the entrance to the 850 Adit.
Additional safety works included the replacement of caps on several shafts and the making safe of openings to the underground workings.
CDM Smith were appointed as Client’s Representative to provide technical, design, procurement and project management services.
