US regulators propose tougher clean air rule

(AP) _ The Obama administration is proposing to strengthen a crucial air pollution health standard.
The U.S. Environmental Protection Agency said Monday it wants to tighten the requirement for the level of nitrogen dioxide concentration in the air.
Nitrogen dioxide is released from motor vehicles, coal burning power plants and factories. It can cause respiratory problems and is of special danger to children and people suffering from asthma. The federal healthy air standard for nitrogen oxide has not been changed in 35 years.
EPA Administrator Lisa Jackson said the proposal reflects the latest scientific findings on what is needed to protect people's health. The EPA issued a proposal is the first step in changing the standard.
