This case history covers the stray current corrosion control program for a natural gas pipeline operator with assets influenced by operation of a nearby direct powered light rail transit system. The first phase of the 40+ mile long transit system went into service in the late 1990s. Part of the operational covenants included a proactive, mutually responsible agreement with the gas company to monitor and manage stray current effects on the gas system infrastructure. Transit track electrical isolation measures were included in the transit system design and construction to control stray current directly at the source. However, these measures are degrading with age resulting in greater stray current leakage and an increase in stray current monitoring and mitigation by the gas company along with increased maintenance and surveillance by the transit agency. This paper highlights the pipeline stray current control program including evaluation procedures and mitigation/corrective measures employed. Most notably is the ongoing cooperation between the gas company and the transit agency to solve issues and maintain effective stray current control in a manner satisfactory to both parties.

Key Words: DC transit interference, track-to-earth resistance, mitigation, IR-compensated potential, datalogging, coupon, electrical resistance corrosion rate probe, cathodic protection.
