The court decision was welcomed by the NSW Resources Regulator for the strong message it sent to mining companies and their directors about properly managing their environmental impacts.

Far Western Stone Quarries mine operator and company director Antony Martin was convicted of the three offences that occurred at the Far Western Stone Quarry, 45km from the outback town of Bourke in the state's northwest.

Martin was fined $8000 for failing to comply with a notice that required environmental remediation works be undertaken.

For failing to submit the mandatory Annual Environmental Management plan and failing to pay annual levies and charges he was put on a conditional release order and ordered to submit the form within six months and pay the outstanding charges.

As part of the order Martin must also be of good behaviour for 12 months.

He was placed on a further conditional release order, with the conviction recorded, for failing to ensure the company paid the mandatory $63,000 mine rehabilitation security deposit.

NSW Resource Regulator director major investigations Brian Glendenning said mine operators were required by law to provide annual reporting on operations and comply with notices issued by the regulator.

"Security deposits must cover the full cost of environmental rehabilitation, so the NSW taxpayer is not left with the bill if a mine operator defaults on its obligations," he said.

 "The court's decision sends a strong message that mining companies, and their directors, must comply with their legal obligations in respect to the management of the environmental impacts of mining - and these will be strictly enforced."
