NEVADA GOVERNOR HAS EPA CONCERNS — Nevada leaders are reacting cautiously to the Environmental Protection Agency’s new, stricter limits on smog-causing pollution. Gov. Brian Sandoval says the rule could punish Nevada for circumstances out of its control, such as pollution from other states and countries. He said he’s keeping all his options on the table as state environmental officials review the rule and its potential consequences. The EPA announced last week that it was limiting ozone pollution to 70 parts per billion, down from 75. Proponents say it will reduce exposure to dangerous pollutants linked to asthma and respiratory illness and prevent hundreds of premature deaths each year. Groups like the American Lung Association had pushed for even stricter limits. Opponents say it’s bad for the economy.
