I'm not sure there is a precedent for this in the past, I do not recall it happening before. AER is blocking an asset sale due to concern about cleaning up the facilities at end of life. The topic is timely giving the recent orphan well discussion that has been ongoing on CP. I had assumed this deal had already gone through, one of my coworkers had a brother who worked at one of the plants but left after Pieridae took over and he wasn't thrilled with the new wawcons. And that was last year IIRC.
