As was mentioned, we have started down that path as the City of Calgary, independently. We have a certain amount of our budget available for new vehicle procurement, which we are earmarking now for CNG bus procurement. We are looking at the P3 model in terms of building the facility. We have been doing it on our own already.
As I mentioned, the majority of the 400 buses that would be CNG would be replacements for our 25-year-old buses. There's a significant amount of investment still needed to be able to deal with the other 600-plus expansion buses that we're going to have. By the time this project is completed, there probably still will be 1,000 buses that we will need to do something with. As I mentioned, at $400,000 a bus, there's no way that even as a fairly sizeable department within the City of Calgary we could get that level of investment.
