SAN JOSE (CBS/AP) — The San Jose Mercury News is reporting that despite revelations that its records did not provide complete details of its natural gas pipeline that exploded in San Bruno last fall, officials at Pacific Gas & Electric Co. say they would not have monitored the pipeline any differently.

PG&E spokesman Joe Molica told the newspaper that even if its records had shown a welded seam, no changes would have been made in how the utility keeps track of the pipeline.

Federal investigators have determined that the blast, which killed eight people and left dozens of homes uninhabitable, originated at a poorly installed weld on the seam.

Several pipeline safety experts have questioned why the utility was unable to identify and repair shoddy welds along the stretch of the 54-year-old pipe.
