An Environmental Protection Agency (EPA) rule approved by the agency Dec.14 calls for a yearlong study of lead levels at 15 airports, according to a story at AOPA.org. The story notes that the rule revises the monitoring requirements for lead emissions from a variety of sources to better assess if areas are complying with the National Ambient Air Quality Standards (NAAQS). But the EPA said it did not have enough information to determine if it should lower the threshold for airports and is requiring the study at specific sites to gather data on airports’ contributions to an area’s ambient lead levels. Read more about this, including a list of the 15 airports, here.
