last december's massive refinery fire in richmond. katherine is here now and has been looking into this with details on the story. >> reporter: chevron is basically acknowledging it is to blame for the huge fire last august admitting its failure to identify and replace the corroded pipe. we know the refinery repairs have been wrapped up and chef ron released this -- chevron released this video saying they expect to resume operations soon and it is promising to improve inspection procedures and says it is inspecting now every pipe in the facility. as for what went wrong august 6 when that leak led to the huge fire, chevron's findings aren't that different from those of federal and state inspectors. chevron admits it mishandled the response to the pipe leak saying in part its workers did not recognize the result of the pipe rupturing and igniting and the 2002 discovery of the pipe was getting really thin and worn and was buried in a soft data base and admits the 2011 inspection passed over that very same pipe which ruptured a year later. federal inspect found -- inspectors have found they failed to inspect the '70s era pipe that leaked despite finding corrosion in other pipes nearby. the problems were so significant cal-osha questioned whether chevron can properly go forward and fix and identify any few -- future problems though it gave them the ok to bring the refinery back on- line. chevron is insisting they have a new protocol for fixing problems and it can prevent a similar incident in the future. >> i'm sure critics will looks over the report very

this time when they ram each other so you can really see it. watch right here. boom. greinke didn't have any momentum, so quentin really got the better of that one. the pair ends up at the bottom of the scrum as teammates then converge. dodgers star matt kemp who you see right there was not happy at all. greinke had to leave the game. he then had to leave the ballpark with his arm in a sling. tempers flared again as the players were leaving their clubhouses in san diego. that's matt kemp and here iscarlos quentin. kemp was mad on the field. quentin got hit by the the pitch and charged the mound. this is as they're exiting the park in san diego. you can see them having words and padres pitcher clayton richards had to step in and try to play peacemaker although it doesn't look like
