New EPA limits will make difference but more may be needed

LANSING — Stricter new smog limits by the U.S. Environment Protection Agency may improve air quality, but some regions of Michigan have a long way to go to meet it, according to an air quality advocacy group. The EPA this month called for ground-level ozone levels of no more than 70 parts per billion, five parts per billion less than the old standard issued in 2008. The American Lung Association considers it a step in the right direction. “We support the ozone standard and we are definitely supportive of making sure that the new standard gets implemented. Even though we think it could be lower- 60 ppb, moving to the 70 ppb is at least moving in the right direction,” said Ken Fletcher, the advocacy specialist for the American Lung Association in Michigan.
