PG&E began work in September 2014 to replace two aging natural gas pipelines that cross Cache Creek near the town of Capay, CA. In September 2015, the HDD Company completed two directional drills on the project, replacing the pipeline that had been exposed on the bottom of Cache Creek. PG&E's Line 400 was permitted in 1960 and constructed in 1961-62. It is a 36-inch pipeline that carries gas from Canada south through the Central Valley. The other pipeline, Line 401 was permitted in 1991 and constructed in 1992. It is a 42-inch natural gas pipeline that runs parallel to Line 400. Both pipelines cross Cache Creek and PG&E decided to replace these pipes with two new pipes that would be laid roughly 80-feet below Cache Creek using directional drilling.
