EPA administrator Lisa Jackson attended a conference in Oakland Tuesday; her first visit to California as EPA chief.
Jackson says she has never seen a time with as much promise and potential for the environment as now.
"Our planet is experiencing a changing climate, our country is entering a global race for clean energy and for jobs with environmental urgency, but also with fierce economic urgency," she said.
Jackson says the Obama administration has accomplished more in eight months than the Bush administration did in eight years.
But she says more needs to be done, especially when it comes to the Delta and San Francisco Bay.
