I'll turn that question over to Mr. Cline in a moment.
What I want to make sure people understand is that when we have these facilities out there, the companies are visiting these sites on a regular basis. The Alberta Energy and Utilities Board is visiting these sites on a regular basis too. So there is an ongoing evaluation of the condition of the sites, there are audits that are done, and there's information that needs to be submitted to the regulator that confirms the adequacy of the work that is being done—and it is reviewed. I think it's important to understand that there is a strong regulatory oversight here.
It's also important I think to make sure we don't draw conclusions that there are problems on the basis of what might be occurring, the “what ifs”. From a risk management perspective, the industry and the regulatory environment are well aware of the risk environment that's out there and have measures in place at the front end—the design end—of the process to mitigate those measures, and through the operations phase and indeed in the abandonment phase to deal with them. So while there may be concerns about potential risk, I think it's important for folks to understand that those potential risks are understood and are being managed.
