Australia: The New South Wales Environment Protection Authority (EPA) has fined Port Kembla Milling’s cement and slag grinding plant US$23,000 for allegedly storing raw materials in the open, in breach of its licence conditions. Raw materials, including gypsum and limestone, were allegedly stored in the open at the subsidiary of Cement Australia on at least five occasions since January 2016 in breach of the site’s planning approval and licence conditions. Such materials should be stored in an enclosed location to prevent dust emissions.

“The requirement to store materials in an enclosed building is a key way to ensure dust emissions from bulk materials are prevented. A measure that is very important given the residential areas near Port Kembla port,” said EPA Regional Director Metropolitan Giselle Howard.

In addition to the fines, the EPA has also required Port Kembla Milling to complete an independent raw materials handling audit to confirm appropriate storage and management systems are put in place. The company has made some initial steps to respond to this request, and the EPA will continue to work with the licensee to ensure full compliance.
