The recovered oil and snow and/or ice are transported by a vacuum line to a storage and transport vehicle towed by the tractor. The storage and transport vehicle may be self-propelled and includes an onboard storage tank which is heated to melt the snow and/or ice and a separator for separating air used to transport the contaminated snow and/or ice to the tank. The tractor includes onboard prime movers for operating a vacuum pump for collecting the contaminated snow and/or ice and a prime mover for propulsion and operation of the skimming and collection mechanism.
