problem line but we discovered much of the line is through residential areas. this is another large section of pipeline, a mile from the explosi explosion. it is feet away from many homes. the location of pipelines like this are generally kept secret to literally provide terrorists are coming in and blowing them up so it's possible that people might be living next to them and not even know it. the only way to tell may be from the yellow sidewalk markers that, for example, used to alert construction crews of danger. it won't be until 2013 now until that section of pipe it. >> identified a new years ago will be fixed. >> if they replaced that section, maybe they would have found something that led them to look a mile or two south of there. we don't know that. but we do know the project was slated for 2009. it didn't get done. and now, they're proposing to do it again in 2013.
