That’s the word from a new clean air report issued Monday by the Maryland Department of the Environment.

The report says the percentage of days with good or moderate air quality rose to more than 91 percent last year. That’s up from about 85 percent between 2001 and 2005. However, the report also says the state isn’t likely to meet new stricter ozone standards because 70 percent of Maryland’s air pollution comes from out of state.
