How can we make offshore drilling safer, cleaner?
Dear EarthTalk: Given the huge oil spill in the Gulf of Mexico last month, isnâ€™t it high time the government put a stop to offshore oil drilling once and for all? Short of banning it altogether, what can be done to prevent explosions, leaks and spills moving forward?
The explosion of BPâ€™s Deepwater Horizon drill rig on April 20 and the resultant oil spill now consuming coastal regions of the Gulf of Mexico could not have come at a worse time for President Obama, who only recently renewed a push to expand drilling off the coast of Virginia and other regions of the United States.
The debate over whether to tap offshore oil reserves has been raging since extraction methods became feasible in the 1950s. It heated up in 2008 when George W. Bush convinced Congress to lift a 27-year-old moratorium on offshore drilling outside of the already developed western Gulf of Mexico and some areas off Alaska.
Barack Obama had historically toed the Democratic party line on offshore drilling â€” donâ€™t allow it â€” but changed his tune during his 2008 campaign to compromise with pro-drilling Republicans if they would play ball with him on his carbon emissions reduction and energy efficiency initiatives. Then on March 31, three weeks prior to the Deepwater Horizon explosion, which killed 11 workers and has caused untold environmental damage, Obama called for new offshore drilling in the Atlantic from Delaware to central Florida and in Alaskaâ€™s untapped northern waters. He also asked Congress to lift the ban on offshore drilling in the oil-rich eastern Gulf of Mexico, just 125 miles from Floridaâ€™s beaches.
Oil industry representatives maintain their equipment and processes are safer than ever. The U.S. Minerals and Management Service (MMS) blames the vast majority of the 1,400 offshore drilling accidents in U.S. waters between 2001 and 2007 on â€œhuman error,â€ not malfunctioning equipment, though some might argue that the distinction is irrelevant because there will always be human error. The MMS says it was already in the process of drafting new regulations that would require rig operators to develop programs focused on preventing human error, including operations audits once every three years for each rig.
Some Congress members donâ€™t think the new regulations are enough, especially in the wake of the BP tragedy. U.S. Sen. Bill Nelson, a Florida Democrat who has led opposition to offshore drilling, has now called for a congressional investigation of safety practices at offshore oil rigs, and has asked the U.S. Interior Department to undertake a full review of all U.S. drilling accidents over at least the last decade.
