Gulf spill: BP gets go ahead for full-scale underwater use of dispersants
All week, U.S. federal agencies have been evaluating an unprecedented use of oil dispersants: to break up crude spewing from the seafloor. BP won preliminary approval to try them in limited tests against an ongoing torrent of oil spewing from the base of a devastated exploration rig in the Gulf of Mexico. Late morning on May 15, the Environmental Protection Agency and the Coast Guard issued their joint approval for a scale-up of the novel subsea application of these chemicals.

EPA issues greenhouse-gas rules for new factories and more
EPA released new rules on greenhouse-gas emissions for new power plants, factories and oil refineries — any big new facility, really that emits huge amounts of carbon dioxide, methane, nitrous oxide, or any of several other classes of chemicals. Existing facilities can continue to spew greenhouse gases at current levels.

Spill update: From booms to dispersants
Choppy seas prevailed in the northern Gulf of Mexico on May 13, with even protected waters hostingrough 4 to 5 foot waves, according to the Coast Guard. But three-plus weeks into the Deepwater Horizon explosion and ensuing spill from a BP exploratory well, measures to respond to the catastrophe continued ramping up.

Chinese would turn cigarette butts into steel’s guardian
People smoke a lot of cigarettes, which leads to a lot of trash. Tom Novotny has done the math: An estimated 5.6 trillion butts each year end up littering the global environment. But Chinese researchers have a solution: recycling. Their new data indicate that an aqueous extract of stinky butts makes a great corrosion inhibitor for steel.
