Secondary Containment Retrofitting Using a Bituminous Geomembrane
The City of Portland (OR) requires that bulk fuel terminals install impervious secondary containments (i.e. liners) around tanks or facilities built after 2004. To satisfy this requirement when planning to replace a group of tanks with two large tanks at its Willbridge Terminal in Portland, (Oregon) Chevron compared different liner options. The site is essentially flat and numerous tanks, pipelines, and ancillary structures exist within the secondary containment so any earthwork to cover a liner or promote drainage would have been very difficult. The number of penetrations, pipe support, and pipes crisscrossing the facility favored a liner that could be pieced together and seamed easily. An exposed liner consisting of a 160 mil Bituminous Geomembrane was ranked as the optimum solution. The City of Portland approved the design and the liner was installed in 2010 and has worked to the satisfaction of the Terminal operators. The paper describes the selection process, design, installation, and performance of the geomembrane thus far.
