I'm not going to comment on the appropriateness of government policy in that area, but in the majority of cases in which there is material being released from the industry into a receiving environment, it is up to industry to do the monitoring under the surveillance and audit of either the provincial or federal government. It has to do with the amount of human resources available within those ministries. Don't get the impression that the companies have a licence to run wild. From what I can see, the audit procedure is pretty rigorous, but there could be problems with it. I'm not a regulator.
