The Environment Protection Authority inspected the Australian Glass factory in Rushdale Street last month.
The EPA's southern metro manager Leigh Bryant said that following numerous reports of noise pollution in the area, the elevated noise levels were traced back to Australian Glass.
"Australian Glass is required to make long-term fixes to its equipment and plant by November," Mr. Bryant said.
"Once this is in place, the company will need to demonstrate that any noise generated from the premises falls within the required evening noise limits."
However, an Australian Glass spokesman was evasive when asked about the EPA inspection.
He initially said he was unaware of the issue, but later admitted the company was notified by the EPA of an issue.
"We've met our obligations with compliance," he said.
If the company fails to comply with the EPA ruling and the matter goes to court, it face fines of up to $330,000 or $160,000 for every day the offence continues.
