Yes I did read that in the docs and I am only in the 300's somewhere. There were to be discontinued and abandoned and I do believe when they do that they empty the tanks but maybe do not go in them.
When they used the word abandoned I thought that was odd because if that was my land and they no longer were going to be using them I would want them torn down and gone. And they are on private ranch land and the oil company maintains the property and roads leading to them plus pays the rancher land use fees or if the oil is actually pumped out of that land they get royalties, something to do with mineral rights. To me it is all confusing but I was told that when I was out there.
But yes it was in the docs somewhere that they were to be shut down in the future.
P.S. and sorry do not remember the page number but I am only up to 369 so before that somewhere in there!!!!
