Good, should have stopped that wasteful crap years ago, it's fast becoming a strategic issue. Even though we have a good supply in Amarillo, the processing equipment is old, and not being used much due to it's condition. It will not supply our needs fully in the near future, and we have more than anyplace on the planet. There is no way to reclaim it once it gets out. Currently a lot of US firms are being pushed to buy what little we can find overseas in order to preserve our supply.
Once it's gone, it's gone forever.....................and that day is coming soon.
