The U.S.-based company could face a $500,000 for failing to notify regulators, though no one was injured in the 2015 incident
CALGARY—The Alberta Energy Regulator has laid three charges against Colorado-based Westmoreland Coal Company and subsidiary Prairie Mines & Royalty ULC after a bulldozer was partially buried two years ago.
AER spokesman Ryan Bartlett says about 3,300 cubic metres of material slid from a high wall at the Coal Valley Mine south of Edson, Alta., partly covering the bulldozer, on March 21, 2015.
No one was injured.
Bartlett says Westmoreland Coal Company reported the incident at the surface mine two days later.
Both Westmoreland Coal Company and Prairie Mines & Royalty have been charged with failing to notify the AER of an incident as soon as practicable and modifying a mining plan without AER approval.
Each company faces a maximum penalty of $500,000 per offence.
