According to the American Petroleum institute and the Association of Oil Pipe Lines, oil pipelines will lose 1.5 billion bbl/yr of their throughput capacity if the U.S. Department of Transportation adopts proposed safety standards, and the proposed changes will cost $500 million without contributing to public safety. The proposals would require pipelines to reduce their operating pressures to stress levels not exceeding 72% of the minimum yield strength of the pipe, based on minimum wall thickness rather than on nominal wall thickness. Pipelines would also be required to reduce operating pressures by eliminating the present 10% allowance in the B31.4 code for surges and other deviations from normal operations. The combined effect of these two proposals is a reduction in pipeline pressures of 18% and a total reduction in existing delivery capacity of 11%. To regain the lost capacity would necessitate building new pumping stations or loop lines.
