Clean air advocates, many sporting "Don't Trash Our Lungs" t-shirts, spoke out yesterday at public hearings in Los Angeles and Houston for much-needed reductions in toxic air pollution. Held by the U.S. Environmental Protection Agency, the hearings focused on recent EPA proposals to cut emissions of hazardous air pollutants like mercury and other toxic metals at nearly 100,000 facilities nationwide.

While aspects of the EPA's proposals will result in significant benefits to public health if finalized, the agency also made an irresponsible and dangerous offering to industry in the form of a loophole that would allow many facilities to burn industrial wastes without any meaningful oversight or pollution controls.

I attended the L.A. hearing to ask that EPA issue final standards that are maximally strong and protective of public health and ditch the loophole that endangers communities across the country. Hundreds of Earthjustice supporters in the L.A. area, which is notorious for its poor air quality, also submitted comments asking for the same, and I was able to read excerpts from many of these during my testimony.

Some top stories from the past week at Earthjustice…

This week, Earthjustice scored a big victory for our lungs with the announcement that the EPA is finally abandoning a dangerous rule—granted by the Bush administration—that would permit the unregulated burning of hazardous waste.

BP's latest effort to clean up its soiled image took it into even murkier waters after the oil giant recently began buying search terms like "oil spill" on Google and Yahoo search engines so that the company's official web site would be the first link to appear on a search page.

Amidst a vote on Sen. Murkowski's (R-AK) resolution to bail out big polluters, Earthjustice President Trip Van Noppen called on the Senate to put aside partisan politics and protect the American people by voting against this bill. Thankfully, the Senate has voted 53-47 against the bill.

Campaign manager Brian Smith reported on Interior Secretary Ken Salazar's recent announcement of a memorandum of understanding to establish the Atlantic Offshore Wind Energy Consortium, which has the goal of tapping into the estimated 1 million megawatts of potential wind power that exists off the east coast.

Earthjustice was curious to know just what's in all of those chemical dispersants that we're dropping into the Gulf of Mexico by the millions of gallons, so we filed a Freedom of Information Act request to get more information. Here's what we found (hint: it's not good).

For the first time since oil started flooding the Gulf of Mexico, President Obama has shown passion and vision about where this unfolding tragedy should lead us -- to end our national addiction to oil and other forms of carbon-based energy.

"The next generation will not be held hostage to energy sources from the last century," the president vowed today in a speech clearly aimed at a rising chorus of critics who, like us, wonder why the president has been so inspirationally absent on what may be this nation's worst environmental disaster. Last Friday, while standing amid the oily carnage on a Louisiana beach, Obama did little more than pluck a tar ball from the sand and show it to the press. What a letdown. What a missed opportunity.

Today was better.

In a speech on economics at Canegie Mellon University, President Obama steered straight to the oil spill and said it exemplified what we must leave behind on our way to a clean energy future. "I will make the case for a clean-energy future wherever I can, and I will work with anyone from either party to get this done. But we will get this done," he said. He gave a string of assurances and promises about how he will shape that future, among them these:

While the federal government launches a criminal investigation into the cause of the Deepwater Horizon explosion and oil spill, some in the Senate are still making designs for a big polluter bailout.

On Friday, 13 leading environmental officials joined the ranks of the many who have protested this effort in Senate, which was put forth in a proposal by Senator Lisa Murkowski (R-AK) months ago and will come to a Senate vote on June 10.

Her proposed legislation would keep us hooked on dirty and dangerous fossil fuels, and protect the oil and coal industries from having to clean up their pollution, by removing the Environmental Protection Agency's ability to regulate global warming-causing greenhouse gases. The EPA has this authority by way of the Clean Air Act, one of our nation's most effective and successful environmental laws, and the Supreme Court's 2007 Massachusetts v. EPA ruling.

In a letter to Senate leaders, the bipartisan group of state environmental agency heads and leaders from both coasts and parts in between defends the 40-year-old Clean Air Act, and argues that any reversal or delay of the EPA's science-based findings on the threat of global warming would be unacceptable.
