The regulator says Vesta Energy Ltd. must suspend hydraulic fracturing operations at the site in order to protect the public and the environment.

It says the Calgary-based company must submit a report of all seismic activity in the area since April and specific fracturing data for the well site from Jan. 29 to Monday.

The regulator has also ordered Vesta to file a plan to eliminate or reduce future seismic activity from fracturing.

Hydraulic fracturing involves pumping chemicals and sand underground to break up rocks to help get oil and natural gas flowing.

“A Vesta representative contacted the AER through the 24-hour emergency response number at 06:20 a.m. on March 4, 2019, and informed the AER that seismic activity of magnitude 4.32 was detected due to Vesta’s fracturing at the site, and that Vesta had shut down the fracturing operation,” the regulator said in a release Tuesday.
