Thank you, Mr. Chair. I understand this came about as a result of new accounting procedures required by whoever sets those things. I don’t know whether it’s the Auditor General or what. I am happy to see this. I think our government is too. They realize these liabilities are real and are out there, and it’s nice to have some assessments on which to base what the costs are going to be in the future and today.
I understand that there are two components to this. One is assessing existing sites in a little more depth, rather than just knowing they exist and they do have some degree of liability. We are now trying to quantify that a little bit. We’re also adding in sites that were worked on before, non-operating sites.
In terms of the assessment of work that’s been done on estimating costs of cleanup of sites that we have done in the past, what degree of confidence do we have in those? How deep did they go? Do we expect when we get around to doing the work, we will need more work? Is it likely that these are conservative estimates and there is some chance the final cost will be less than what the current appraisal is? Thank you.
