Mr. Speaker, I was trying to suggest that the Member could draw his own conclusions. I am not able to provide a technical response to the Member's question. I don't want to do a disservice to the mining company. It is important to use words in a proper phrase because we are dealing with an existing business. However, it is true that there is local concern about the high rate of release of certain pollutants from that particular mine. So we can say in general terms that we think it can be reduced by a very high percentage; 90 per cent is the figure we are using. We think within a reasonable time frame, Giant should be expected to upgrade and replace its antiquated equipment so that the rate of pollution -- if I can call it that -- is not continuing indefinitely in the future.
