The basic maintenance standards we have for highways are based on maintenance categories ranging from category one through five on what we call caretaker. Those six levels of maintenance are usually prescribed to a large extent by the volume of traffic. The maintenance manual is about two inches thick. It would describe such things as how often the gravel surface is bladed, how much snow would be allowed to accumulate before it's ploughed, and a whole series of maintenance standards which will depend on the category of the highway. As I said, the higher the volume of traffic and to some extent the more difficult conditions would give it a higher frequency of maintenance.
The Liard/Mackenzie west area have the lowest traffic volumes on the highway system and we are lowering the category by one level which will mean somewhat less frequent blading in the summer, et cetera. And I don't have the maintenance management system with me or memorized, but we can certainly make that available. It's a guideline for the amount of maintenance one would expect; the number of dry bladings per season, for example, one would except to do. The maintenance foreman and superintendent don't follow that standard slavishly. It's a guideline as to what should be expected if conditions warrant. If conditions are good, they may even be able to maintain a level of service with less. If conditions are bad, they may require more. In the end, the judgement of district superintendents and foremen about what is acceptable prevails. But, certainly, the maintenance standard can give you a pretty good idea of what to expect, and that could be made available. Thank you.
