Stolthaven Australia, which operates a liquid fuel storage terminal at Mayfield, has been fined $30,000 for breaching its environment protection licence.
The terminal is approved for an annual throughput of 500-megalitres, but the company advised the EPA that it exceeded its limit by 260-megalitres between October 2013 and October 2014.
The EPA says while it caused no harm to the environment, it takes all licence breaches very seriously.
