Maintenance work at a pipeline control center triggered electrical problems and a rise in gas pressure just before a major transmission line exploded last month in San Bruno, killing eight and setting off an inferno that destroyed dozens of homes, according to a preliminary National Transportation Safety Board report released Wednesday.

It was not clear what, if any, role the pressure change played in the catastrophe, one of the nation's deadliest natural gas pipeline failures in decades. But the link between maintenance trouble and a sudden increase in pressure just before the blast was among the fresh details disclosed by investigators.

Crews were working on a backup power supply system in Milpitas, about 40 miles from the blast site, the NTSB said. During the work, electrical voltage to a pipeline control system dropped, interrupting a signal to a pressure control valve, the report says.

3. I can't remember what the terms were.

Having to wash his cat is fair. Preferably with the assistance of the straw-man he was flogging around that day. A vigorous rub down and a blow dry thrown in and I might be mollified.
