Lessons of the Gulf Oil spill at the 100-day mark

MIAMI — As the Gulf of Mexico oil spill hit the 100-day mark Wednesday, clear lessons have emerged from the stained waters. Some big ones likely to influence future decisions on offshore exploration:
• It doesn't all float: The massive slick largely has vanished — partly consumed by microbes and worked on by wind, waves and sun — but perhaps tens of millions of gallons may be underwater.
The discovery of vast deep sea plumes, believed to be the result of chemical dispersant reducing the gushing flow into suspended droplets, has destroyed conventional wisdom about what happens when oil and seawater mix. Particularly when an unprecedented volume of chemical dispersants is added.
BP initially dismissed they were there. Now, the plumes — likened to underwater clouds of mist — rank among the biggest cleanup concerns. Researchers can't say for sure how big they are, what is likely to happen to them over time or whether the concentrations, which fade from strong near the well to barely detectable 40 miles away, are toxic to marine life.
• When stakes are high, don't cut corners: BP played fast and loose with safety to save time and money, witnesses told a congressional subcommittee. Four days before the disastrous blowout, contractors told BP it needed 21 "centralizers" to stabilize the well before cementing it, but BP saved time and money by using only six. And in choosing the final piece of pipe for the ill-fated well, BP saved $7 million to $10 million by using a "long-string" pipe that reached from the bottom of the well to the seafloor, instead of a "liner tieback." The latter might have prevented gas from flowing up unchecked past the pipe, BP memos said.
Documents also said BP skipped a test to determine if cement had properly bonded to the well and rock formations, which would have been safer but taken 12 hours.
• A little hustle would have helped: For weeks after the April 20 explosion, BP was estimating the flow of oil at 210,000 to 840,000 gallons a day, and responded with a "top hat" containment device capable of sucking up only about 630,000 gallons a day. By mid-June, government scientists were saying the well was spilling 2.1 million gallons a day or more, and the Obama administration demanded a bigger, faster response from BP.
BP then started to hustle. Today it has 800 skimming boats, 4,300 other vessels, 114 aircraft, 3.4 million feet of boom and 24,800 workers. And it has unveiled the Ella G, a 280-foot supply vessel outfitted with four centrifuges capable of slurping up 800,000 gallons of oily water a day.
• It wasn't a heck of a job: The three-month oil spill may not wind up, as some critics charge, "Obama's Katrina." But the administration didn't ace the Gulf Coast history tests, either.
Like the Bush administration after the disastrous 2005 hurricane, the Obama administration was slow to grasp the scale of the spill and, in the first month, gave BP too much credit and leeway as the oil company downplayed the threat and bumbled through failed attempts to plug the gusher.
NOAA, the lead science agency, also drew fire from many scientists, echoed by some congressional members. They contend the agency was slow to tap its expertise, slow to send research vessels and slow to push BP for flow-rate data that would have more quickly shown the blowout to be a disaster of historic proportions.
As the president's poll numbers plunged, the administration's multiagency Unified Command made tougher demands, drawing a $20 billion damage pledge from BP and a dramatically expanded capping effort.
• The Gulf may heal itself faster than thought: Experts say up to 50 percent of spilled oil — the most volatile, toxic part — can evaporate within a week. Another portion can be eaten by naturally occurring microbes, especially in warm Gulf waters. "Oil is a natural product. It's inherently biodegradable," said Terry Hazen, microbial ecologist at the Lawrence Berkeley National Laboratory in California.
Even hurricanes can help. After the massive 1979 Ixtoc I spill in Mexico's Bay of Campeche, Hurricane Frederic was credited with scouring tar balls off the Texas coast. Experts say a hurricane's eggbeater effect on the water might break up oil sheens into small oily particles more easily digested by microbes.
Even water's-edge marshes, crucial to sheltering juvenile shrimp and dampening the surge of hurricanes, have some self-healing abilities. Environmentalists visiting Louisiana's oil-soaked marshes have detected new green sprouts thrusting up through the black goo.
• Regulators shouldn't sleep with industry: It took an epic environmental catastrophe to do what scathing government investigations, years of bipartisan criticism, sex-and-gifts scandals and a $10 billion bureaucratic bungle could not: force the dismantling of the federal agency that regulates the offshore-drilling industry.
The once-obscure Minerals Management Service (MMS) had two main missions: To enforce drilling-safety rules and to collect billions in royalties from the $1-trillion-a-year petroleum industry. It did neither well, costing taxpayers billions in unclaimed royalties and allowing the industry to largely set its safety standards, a hands-off attitude that enabled BP's disastrous blowout.
The agency is being broken up in the wake of the spill. The Obama administration promises to mend regulatory loopholes and end cozy relations.
• Healthy waters mean healthy wallets: From empty hotel rooms along the Florida Panhandle's sugary sands to empty shrimpers' nests in Louisiana, there were many examples of how much Gulf Coast economies depend on clean beaches, wetlands and waters. "This is part of our culture, people have got to understand," said Marylee Orr, executive director of the Lower Mississippi Riverkeeper. "We're part of the whole chain. We consume the food, our little kids are playing in the Gulf. We absolutely have to learn from this."
• A tin ear is no friend in a crisis: Even with his distinguished British accent, BP boss Tony Hayward (who is being replaced as CEO by American Robert Dudley in October) couldn't get away with such gaffes as calling the oil disaster a "tiny" spill into a "very big ocean." Or griping that he, too, wanted the spill to end because "I want my life back." Or taking a Saturday off to attend a luxury yacht race around England's Isle of Wight to cheer on his boat, "Bob." It'll give him something to mull over during those long, dark nights at his new post: BP's digs in Russia.
