The EPA in Evansville issues an air pollution alert, but one environmentalist says the alert came too late.

The alert says fine particulate matter may reach unhealthy levels for sensitive groups.

Environmentalist John Blair says the alert was issued hours after levels reached the "unhealthy" category.

The EPA says the levels rose unexpectedly overnight and that alerts are issued for what is forecast to happen.
