"Americans could breathe more smog and toxic chemicals on summer days if regulators fail to get a handle on companies that use diesel-burning generators as a last line of defense against power outages, a coalition of state officials from the Northeast says in a new report."

"There may be as many as 30,000 backup generators in the Northeast. All together, they could produce 10 gigawatts of electricity, says the Northeast States for Coordinated Air Use Management, or NESCAUM, which represents the six New England states, New York and New Jersey."
