But about three miles off the coast of Alaska, BP is moving ahead with a controversial and potentially record-setting project to drill two miles under the sea and then six to eight miles horizontally to reach what is believed to be a 100-million-barrel reservoir of oil under federal waters.

All other new projects in the Arctic have been halted by the Obama administration’s moratorium on offshore drilling, including more traditional projects like Shell Oil’s plans to drill three wells in the Chukchi Sea and two in the Beaufort…

Rather than conducting their own independent analysis, federal regulators, in a break from usual practice, allowed BP in 2007 to write its own environmental review for the project as well as its own consultation documents relating to the Endangered Species Act, according to two scientists from the Alaska office of the federal Mineral Management Service that oversees drilling.

The environmental assessment was taken away from the agency’s unit that typically handles such reviews, and put in the hands of a different division that was more pro-drilling, said the scientists, who discussed the process because they remained opposed to how it was handled.
