The Department of Environment and Conservation has imposed strict new environmental conditions on a Cockburn Cement cement factory, south of Perth.

It follows nearly 70 complaints from residents about corrosive dust emissions at Cockburn’s Munster facility.

The DEC has issued the company with a new environmental protection licence, which compels it to reduce its kiln dust emissions and install three new air monitoring stations.

Cockburn Cement has three weeks to appeal against the changes.
