Pipeline transport oil-contaminated sediment and debris from the Kalamazoo River system. However, oil was still being found in affected waters in October 2012. Fossil fuels can be transported by pipeline, rail, truck, or ship, though natural gas requires compression or liquification to make vehicle transport economical. For transport of crude oil via these four modes, various reports rank pipelines as proportionately causing less human death and property damage than rail and truck, spilling less oil than truck, and having more environmental impact than truck or rail (mostly due to impact on habitat; ship transport impacts marine habitat to a large degree).

New storage depots were built on this pipeline and a third new import facility was constructed on the Humber. The first commercial usage of the system was immediately after the war to supply a depot on the River Severn from Avonmouth. In the early 1950s some aviation fuel was pumped from Avonmouth to a depot on the Thames to supply Heathrow airport by road tanker from there. Esso also used the network to pump
