Yeah, I assume there's gotta be a better way. Like clogging it beyond repair (shut off+completely solidified), siphoning operations (assuming a spill isn't caused)... And in either case, converting it into something less bad and/or storing the carbon in a stable manner.
(Although even rebuilding from what I see may be at least $1M-$2M per mile, they sure have the money but it's not insignificant either)
Ah yes, in 50 years we can make a real difference! If even that due to our flawed (FPtP) voting system and money in politics. We should give it a try though, as I don't think anyone has ever tried it before. Particularly as I assume these sorts of problems became known just this year... because otherwise we would've fixed them with our caring, functional, and proactive government ((/s))
