>> femsa does regular audits. they actually did a very detailed assessment of this particular silver tip line in june of this year. >> had you been notified of any problems that they saw? let's talk about period from 2003 on. >> the last time we did an actual inline inspection was in 2009. after that inspection was completed, femsa looked at those records and they identified four, five things that they wanted us to respond to. they were not particularly integrity issues on the pipeline but they were items that they identified that we needed to improve. that included removing some vegetation near a portion of the pipeline, adding some paint on a portion that was above ground. doing some additional walking patrols on the pipeline and not just ariel patrols. actually correcting them on top of the valve bonnets. those are things that all responded to and at the time this incident occurred we did not have any outstanding issues from a regulatory standpoint on this pipeline. >> i have a list of criticism and complaints
