“Unit” would be actually either a transport vessel that's used to haul product on the road, or the tank used to pull it in the field that is applying product to the ground. So there are marking requirements for these vessels, because they do travel on the road and they are transporting dangerous goods.
When looking at new marking requirements that will come in for all anhydrous ammonia vessels beginning in 2008, there are requirements to remove the current decals and put the new markings back on that are being required by Transport Canada. So there's physical labour. There's repainting required. It's not just taking a sticker off and putting a new sticker back on. These are well adhered to the tank, for obvious reasons, because they spend 100% of their time outdoors, so there's a lot of weathering required. So scraping, manual labour, and purchasing of decals are all part of the package to meet the new marketing requirements that are being dictated by Transport Canada.
