Companies ordered to clean up former sour gas plant site in central Alberta

The Alberta government says no remedial work has been undertaken by ConocoPhillips Canada or Bonavista at the Crossfield sour gas processing plant



EDMONTON—The Alberta government has ordered ConocoPhillips Canada Resources Corp. and Bonavista Energy Corp. to clean up the site of a former sour gas plant.

The government says ConocoPhillips Canada is the holder of the Environmental Protection and Enforcement Act approval for the reclamation of the Crossfield sour gas processing plant and is the surface lease holder.

It says Bonavista Energy obtained the Alberta Energy Regulator well licence from ConocoPhillps Canada in January 2003.

A 2010 report identified petroleum hydrocarbons, chloride and metals in groundwater and soil exceeding the provincial guidelines on the well and plant site and extending beyond those boundaries.

The Alberta government says no further site investigations, soil/groundwater sampling events or remedial work have been undertaken by ConocoPhillips Canada or Bonavista since then.

The enforcement order requires ConocoPhillips Canada and Bonavista to submit a delineation plan, prepared by a qualified environmental professional, for government approval.

Tney must also submit a written remediation plan; regularly scheduled status reports; and upon completion of the work, a final report.
