The Federal Aviation Administration has released a long-anticipated report that gives a green light to commercial passenger flights at Paine Field south of Everett, Wash.
The report issued Tuesday reinforces the agency's earlier opinions that such flights would not significantly increase noise, traffic or pollution in nearby communities.
The FAA has been assessing the issue since 2008, with Allegiant Air first expressed interest in providing regional flights.
Opponents say the FAA's assessment doesn't account for potential long-term effects. They would like a more thorough study.
The Seattle Times says there is a 60-day appeal period.
Before flights could begin, The Daily Herald reports that Snohomish County would need to build a small terminal and would need a certificate authorizing commercial flights at the airport. Interested airlines would need to obtain certificates to operate out of Paine Field.
The airport has been used primarily for private planes, Boeing service and test flights and military operations.
