No they don't. If it's not regulated they do what they want whenever they feel like it.

But the 34-inch pipe has been down since March, when a dime-sized hole caused by corrosion sent nearly 5,000 barrels of crude spilling out across the snow. The oil has been cleaned up, leaving behind a bare two-acre patch of ground, but the leak - and the subsequent discovery that six miles of BP (Charts) pipeline was badly corroded - led not only to the shutdown of much of Prudhoe Bay and the loss of hundreds of millions of dollars but also to a PR disaster that, in a single blow, undid the green reputation CEO John Browne had meticulously crafted for BP over the past decade.
Since the March leak and the subsequent shutdown this summer, much of the controversy has focused on a practice called pigging
- sending a device known as a pig through the pipe (old oilfield hands say pigs take their name from the squealing noise they make going down the line) to clean it as well as monitor it for corrosion, cracks, sediment deposits, and other threats that might lead to a leak. Practices vary, but everyone now agrees the low-velocity transit lines that failed should have been pigged more often
. On the west side of Prudhoe Bay, they were last cleaned and checked in 1998, while on the eastern side of the field, the last pig was run in 1991
. The Trans-Alaska Pipeline, by contrast, is pigged every 14 days.
They don't police themselves. Sounds like you have nothing but blind trust in corporations where that trust doesn't belong and damn sure was never earned.
