Project Closure

We work collaboratively with government and companies to develop and implement liability management programs for all energy sectors, which help to protect Albertans from significant potential environmental issues and costs associated with the closure of energy projects.

We use a liability management rating (LMR) to help us assess a company’s ability to address its abandonment, remediation, and reclamation obligations. The LMR is calculated as a ratio of a company’s deemed assets (production) to its deemed liabilities (abandonment and reclamation costs). The LMR is used to assess liability in three of our liability management programs:

What We Expect

We expect companies to maintain an LMR above 1.0; otherwise we require a security deposit to be made to cover abandonment, remediation, and reclamation costs if a company cannot meet its obligations. A company can manage or improve its LMR by

  • reducing liability (by abandoning or reclaiming sites or selling less-productive assets), or
  • increasing assets (by purchasing highly productive sites or improving production on existing sites).

Sharing Information

A company can view a full breakdown of its LMR through our Digital Data Submission (DDS) system.

We share security-adjusted LMRs and debts owed in our LMR reports below, and on our Debtor Registry, which is updated monthly.
