A BENDIGO-BASED company did not have permission from owners when quarrying sand near Rochester, the state mining regulator alleges.
It also did not have Earth Resources Regulation's permission either, the authority says.
"There are many quarry operators doing the right thing in a competitive environment and we'll step in to protect them if we believe someone is unfairly undercutting the market," Earth Resources executive director Anthony Hurst said.
The regulator's investigation into the Bendigo-based company - whose name has not been disclosed - is continuing.
The company is accused of operating a quarry 11km west of Rochester in Digorra.
"Our inspectors frequently conduct spot checks around the state to ensure quarry activities are being conducted properly, safely and without harm to the community or environment," Mr Hurst said.
VICTORIA'S mining regulator has shut down a quarry allegedly operating without approval north of Bendigo.
It comes after Earth Resources Regulation conducted an aerial survey and ground inspection at a site in Diggora, near Rochester.
The regulator alleges a Bendigo-based company has been excavating land without an approved work plan for the area.
Vehicles were also observed collecting material from the site and transporting it north, across the border into New South Wales.
In early September, the company was issued with a notice to stop work for the site.
Further investigations by the regulator revealed at least six trucks continued collecting sand from the site after the stop work notice had been issued.
While operations at the site have now ceased, the regulator's investigation, which could result in enforcement action through the courts, remains ongoing.
Should the Bendigo-based quarry operator be found to have excavated land without an approved work authority plan it faces a maximum fine of $165,000 per offence.
