EPA Administrator Lisa Jackson stepping down after tumultuous term

The Obama administration's chief environmental watchdog, EPA Administrator Lisa Jackson, is stepping down after a nearly four-year tenure marked by high-profile brawls over global warming pollution, the Keystone XL oil pipeline, new controls on coal-fired plants and several other hot-button issues that affect the nation's economy and people's health. Jackson, the agency's first black administrator, constantly found herself caught between administration pledges to solve controversial environmental problems and steady resistance from Republicans and industrial groups who complained that the agency's rules destroyed jobs and made it harder for American companies to compete internationally. The GOP chairman of the House Energy and Commerce Committee, Rep. Fred Upton, said last year that Jackson would need her own parking spot at the Capitol because he planned to bring her in so frequently for questioning. Republican presidential nominee Mitt Romney called for her firing, a stance that had little downside during the GOP primary. Environmental groups had high expectations for the Obama administration after eight years of President George W. Bush, a Texas oilman who rebuffed the agency's scientists and refused to take action on climate change. Jackson came into office promising a more active EPA. But she soon learned that changes would not occur as quickly as she had hoped. Jackson watched as a Democratic-led effort to reduce global warming emissions passed the House in 2009 but was abandoned by the Senate as economic concerns became the priority. The concept behind the bill, referred to as cap-and-trade, would have set up a system in which power companies bought and sold pollution rights. Jackson experienced another big setback last year when the administration scrubbed a clean-air regulation aimed at reducing health-threatening smog. Republican lawmakers had been hammering the president over the proposed rule, accusing his administration of making it harder for companies to create jobs. Jackson had some victories, too. During her tenure, the administration finalized a new rule doubling fuel efficiency standards for cars and light trucks. The requirements will be phased in over 13 years and eventually require all new vehicles to average 54.5 mpg, up from 28.6 mpg at the end of last year. She shepherded another rule that forces power plants to control mercury and other toxic pollutants for the first time. Previously, the nation's coal- and oil-fired power plants had been allowed to run without addressing their full environmental and public health costs. Jackson also helped persuade the administration to table the controversial Keystone XL pipeline, which would have brought carbon-heavy tar sands oil from Canada to refineries in Texas...more And I thought every decision in the Obama adm. would be based on "science".
