Interior Secretary Ken Salazar, who oversaw a moratorium on offshore drilling after the BP oil spill, will step down in March, Obama administration officials said Wednesday.
Salazar has run the Interior Department throughout President Barack Obama's first term.
A former senator from Colorado, Salazar pushed renewable power such as solar and wind, but gained the most attention for his role in the drilling moratorium, a key part of the administration's response to the April 2010 explosion of the Deepwater Horizon rig in the Gulf of Mexico. It was one of the largest environmental disasters in U.S. history and led to the unprecedented shutdown of offshore drilling.
Business groups and Gulf Coast political leaders said the shutdown crippled the oil and gas industry and cost thousands of jobs, even aboard rigs not operated by BP PLC.
But Salazar said the industry-wide moratorium was the correct call.
"I think we're in the right direction," he told The Associated Press during a July 2010 tour of the Gulf, adding that his ultimate goal was to allow deepwater operations to resume safely.
Salazar acknowledged that the drilling ban caused hardship, but he said his job was to protect the public and the environment even as the administration tried to boost domestic energy production.
The moratorium was lifted in October 2010, although offshore drilling operations did not begin for several more months. Some Gulf Coast lawmakers continue to complain about the slow pace of drilling permits under the Interior Department, which renamed and revamped the agency that oversees offshore drilling in the wake of the spill.
Salazar also approved the nation's first offshore wind farm, Cape Wind, off the Massachusetts coast.
On land, Salazar has promoted solar power in the West and Southwest, approving an unprecedented number of projects, even as oil and gas continue to be approved on federal land.
Salazar also oversaw the settlement of a multibillion dispute with Native American tribes that had lingered for more than a decade.
Salazar tangled with oil companies throughout his tenure.
"We don't believe we ought to be drilling anywhere and everywhere," Salazar said in 2010, before the BP spill. "We believe we need a balanced approach and a thoughtful approach" that allows development of oil and gas leases on public lands while also protecting national parks, endangered species and municipal watersheds.
Salazar criticized the Bush administration for what he called a "headlong rush" to lease public lands. Early in his tenure, Salazar suspended 60 of 77 leases in Utah that had been approved by the Bush administration.
"In the prior administration the oil and gas industry were the kings of the world. Whatever they wanted to happen, happened," Salazar said in January 2010, adding that those days were over.
Salazar, 57, is the latest Cabinet secretary to leave the administration as Obama heads into his second term. Secretary of State Hillary Rodham Clinton, Pentagon chief Leon Panetta, Treasury Secretary Timothy Geithner and Labor Secretary Hilda Solis are also leaving. Energy Secretary Steven Chu is widely expected to leave, though his departure has not been announced. Environmental Protection Agency chief Lisa Jackson has announced that she will leave.
The administration officials who discussed his plans spoke on the condition of anonymity because they were not authorized to speak publicly before any announcement.
