The document discusses how existing technologies could be applied to pipelines to contain leaks. It argues that pipelines should be required to have the same in-situ containment regulations as stationary fuel tanks. A protective underlayment lining the pipeline right-of-way could contain and channel leaks to underground holding tanks or ponds. The technology for such a lining system already exists, as canals and landfills are already lined in similar ways. An over-matting could also funnel fuel fumes to sensors to detect even small leaks.
