In 2006, the U.S. Department of Transportation, Pipeline and
Hazardous Materials Safety Administration (PHMSA) granted a special
permit to enable Alliance Pipeline to increase the maximum allowable
operating pressure (MAOP) on its 36-inch pipeline. On December 16, 2007
the company safely and successfully completed the third and final phase
of the pressure increase from 1740 psi to the approved 1935 psi. Each
phase involved extensive engineering and technical analysis, additional
pipeline safety and integrity surveys and approval from PHMSA. The
increase in pressure enhances operating efficiency by reducing
compressor fuel consumption, which lowers green house gas emissions and
costs of transporting natural gas on the Alliance Pipeline system.
The increased MAOP is consistent with the engineering basis used on
the Canadian portion of the Alliance Pipeline system and other
international safety standards. The special permit was approved
following a rigorous technical review by PHMSA, in which the company
demonstrated that even at a higher operating pressure, pipeline safety
will be maintained and the integrity of the system will be enhanced
through increased maintenance, inspection, monitoring, control and
reporting standards to levels that exceed existing regulatory
requirements.
"At a time when North American energy needs are increasing,
this special permit enables Alliance to more effectively utilize our
existing system to address the need, rather than building new
infrastructure," said Mike McGonagill, Alliance Pipeline's
chief operating officer. "We applaud the regulators for their
foresight, cooperation and diligence."
As one of North America's newest and most technologically
advanced pipeline system, Alliance Pipeline has incorporated 50 years of
best practices into the pipeline design and operation and was built to
higher standards than the majority of pipelines currently in operation.
Alliance Pipeline is the first US system to operate at 80% of the
specified minimum yield strength (SMYS) under a special permit.
"The process and issuance of the special permit has redefined the
standards for the industry. Newer systems can operate more efficiently
at increased pressures and are held accountable to higher
standards," said Mike McGonagill. Current U.S. regulations
typically allow operation up to 72% of SMYS.
