PG&E spokeswoman Brandi Ehlers described the work as a “routine upgrade” of the 8-inch steel transmission line that carries natural gas on the north end of town. It is part of the utility’s Pipeline Safety Enhancement Plan.
In a statement released by PG&E, John Martin, gas superintendent for Stockton and Yosemite Divisions, stated that the pipeline replacement would make Tracy’s natural gas system safer.
“We appreciate the support and patience of area residents and businesses while we conduct this important gas infrastructure work,” Martin said.
Ehlers said the work would be divided into two phases. On Thursday, crews began the first phase, which consists of boring holes through the asphalt in the westbound lanes on the north side of Grant Line Road to locate other nearby utility lines. That phase will continue through the end of April.
The second phase of the pipe replacement is scheduled from mid-July through August.
“We will be doing open trenching, and it will occur in stages as we move down the line,” Ehlers said. “The entire 4,400 feet won’t be open-trenched all at once.”
Most of the work will be in the right lane of westbound Grant Line Road, which will be closed during the construction. PG&E will keep one westbound lane open for access to homes and businesses.
Ehlers said that during the upgrade, crews will vent natural gas from the lines, and people who live and work nearby may smell it in the area. The gas is expected to dissipate quickly, but anyone who has a concern about a natural gas odor can call PG&E at 800-743-5000.
The pipeline on Grant Line Road was identified for replacement after the road widening project that began in 2012.
