Nine Michigan counties exceed the U.S. Environmental Protection Agency’s allowable levels for soot particles in the air, though pollution levels have been on the decline for two years.
The EPA announced Tuesday that Michigan must develop a plan to reduce fine particulate pollution in seven southeastern Michigan counties and in Kent and Ottawa counties in central-west Michigan.
Kent and Ottawa counties in West Michigan are new to the EPA list of air-quality violators and news channel WMMT reports that the EPA attributes the pollution in these counties to coal-burning power plants in Ottawa county.
Jim Haywood, meteorologist with the Michigan Department of Environmental Quality (MDEQ) air-quality division, issued an air-quality advisory for both ozone and elevated particulate levels through this weekend.
Though air pollution is anticipated in much of Michigan through this week, Haywood told the Michigan Independent that the EPA’s announcement about the particulate levels in Michigan air comes as the levels have already begun to decline as a result of actions taken to reduce ozone formation.
“Detroit is considered to be in trouble according to the standard, and we are trying to come up with a statewide plan to reduce particulate levels,“ he said.
“But over the last two years, particulate levels have been coming down because measures that were taken to reduce ozone formation — reduction of nitrogen dioxide emissions from power plants and reformulating gasoline — have had the added benefit of reducing the formation of fine particles.”
“Every time you do something good,” he said, “it has a ripple effect.”
