A Melbourne company has added to its growing list of environmental breaches by contaminating a wetland with chemicals.
Sunshine West company VIP Steel Packaging was fined $15,000 for the illegal discharge of a white milky chemical substance that entered a local wetland, the Environment Protection Authority said on Wednesday.
"An EPA officer was able to trace the pollution back to the premises of VIP Steel Packaging where it was found to be entering a stormwater pit," EPA Metro manager Daniel Hunt said.
"The officer then attended Kororoit Creek and found two large ponds full of white liquid with the same type of odour and contaminants," Mr Hunt said.
The EPA says the chemical could have had an acute toxic affect on plants an animals in local waterways.
In addition to the fine, the company was ordered to remove thousands of litres of contaminated water from ponds and the stormwater system.
The company has now been fined more than $40,000 by EPA since December 2014 following previous offences for storing waste it was not licensed to receive at its premises.
