"EPA Weighs Adding More Lead-Emission Monitors"

"The Obama administration moved Wednesday to expand a national network of monitors to track lead emissions, a troublesome source of industrial air pollution that continues to plague Chicago and other urban areas.

Rules proposed by the Environmental Protection Agency would re-evaluate whether more monitors are needed in large cities and close to factories that emit the toxic metal. The policy shift is a response to rules imposed last year by the Bush administration that exempted scores of polluters from scrutiny, including at least a dozen operating in Illinois.

The monitors will help determine whether factories are complying with tougher limits on airborne lead pollution. Faced with a court order, the EPA last fall lowered the limit to 0.15 micrograms of lead per cubic meter of air, 10 times more stringent than the old standard."
