BP plans to keep new cap on well permanently
Good. They also are apparently on schedule to finish relief wells late this month or early next month.
This has been a disaster but some good has come out of it. Bad actors (BP) and good actors (Exxon) have been identified, structural weakness in response plans have been identified and hopefully corrected, and despite the length of time it took it has now been proven that a lek of this type can be dealt with. If it were to happen again I think things would move much faster. None of this makes up for the harm that BP caused but it is something that can be built on to prevent such tragedies in the future.
