Two items that might be of interest.
We were driving down a street that parallels the BNSF mainline just east of Spokane and saw a local freight with about 10-12 cars - and a caboose! Been a while. No idea why, since BNSF got rid of them many years back. And it was a BNSF caboose.
BNSF built a fueling facility a few miles over the Idaho border from Spokane. It opened September 1st. Since it was over the aquifer that provides all of Spokane and surrounding area water, there was considerable controversy over it. The plans were modified to make it impossible for any pollution to get to the aquifer. I believe the engineering firm said chances were "infinitesimal". Article in todays paper - it leaked! Into the ground from a buried PVC pipe which apparently had no second containment layer. Didn't even take 4 months for the "infinitesimal" chance to occur.
BNSF doesn't know if the break was recent or as old as 3+ months. So we don't know how much leaked, the exact composition of the effluent, or how far it penetrated. Test wells are now being dug.
It was a pipe carrying oily waste water instead of straight diesel, so maybe we'll be lucky this time. But BNSF and their engineering firm really have egg on their faces.
