NYT by JOHN M. BRODER and CLIFFORD KRAUSS.  After listening to their findings about the BP William K. Reilly, Bill Reilly, Deepwater Horizon, EPA, Conocophillips, Arctic drilling, chukchi, beaufort sea, alaska, Photo by Dave Harbouraccident and the safety of deepwater drilling, the president abruptly changed the subject.  “Where are you coming out on the offshore Arctic?” he asked.  William K. Reilly (NGP Photo), a former chief of the Environmental Protection Agency and a commission co-chairman, was startled, as was Carol M. Browner, the president’s top adviser at the time on energy and climate change. Although a proposal by Shell to drill in the Arctic had been a source of dissension, it was not a major focus of the panel’s work.  “It’s not deep water, right?” the president said, noting that Shell’s proposal involved low-pressure wells in 150 feet of water, nothing like BP’s 5,000-foot high-pressure well that blew out in the gulf.  “What that told me,” Mr. Reilly later recounted, “was that the president had already gotten deeply into this issue and was prepared to go forward.”
