Laramie, Wy – The Environmental Protection Agency just put out a list of counties where ground level ozone does not meet health standards. But, none of these counties are in Wyoming. Environmental Scientist for the E-P-A Tim Russ says the state only has two monitoring sites, one in Yellowstone and the other in the Thunder Basin Grassland. He says right now more monitoring is not needed but there could be needed if energy development continues in the state at a high rate.
Ozone aggravates asthma, damages the lining of lungs and makes breathing more difficult. The counties in metro Denver all had unsafe levels of the gas.
