Mr. Speaker, we recognize that. The fact is, they have said the mine has been operating marginally at times, and we do not want to introduce laws or regulations that could force the owners to cease operation of that mine. The intent is to give sufficient time to the owners and operators, and to give them a very clear message that they cannot continue operating indefinitely under the present mode of operation, and that we give them sufficient notice that they have to plan to change their mode of operation if they're going to continue operating well into the next few decades. That is the approach we are taking. Thank you.
