Clarence Colliery Incident

On Thursday 2nd July there was an environmental incident at Clarence Colliery.

The incident involved the overflow of material from a holding cell in the reject emplacement area. All relevant agencies and authorities were notified and Centennial has continued to work with these bodies. 

The priority continues to be minimising the impact to the environment and Centennial is achieving this through its management of the incident.

The twenty-two (22) sediment fences erected between the mine site and the Wollangambe River continue to be inspected daily, to prevent the movement of any further material.

Repairs to the holding cell wall were completed on 13th July and clean up activities continue to progress well.  While it is anticipated the clean up will still continue for some time, largely due to the difficult terrain in which the material has been deposited, significant progress has been achieved.

From the day of the incident, Centennial engaged a specialist team to oversee the clean up and over three hundred metres of the impacted area, closest to the Wollangambe, being cleaned up by hand. 

The next stage of the clean up, with EPA approval, includes the introduction of machinery into an area on Clarence’s mining lease closest to the holding cell wall, to assist with the recovery of material and to compliment the clean up by hand.  The clean up timing for the Wollangambe River is being discussed with a variety of State agencies and it is anticipated will commence shortly.

Centennial is in full compliance with the EPA’s ‘Clean Up Notice’ and doing all it can to work with regulators to ensure an appropriate and timely clean up.

It is evident from photos and video footage posted ‘online’ that individuals have entered Clarence’s Mining Lease illegally. It is important that people understand Clarence is an operating coal mine and Centennial is concerned for the safety of anyone entering the mine site without authority.

The cause of the incident is still being investigated.
