Inspecting the Employees at Logan Airport

Logan International Airport is among three U.S. sites selected for 90-day pilot programs to gauge the feasibility of 100 percent security screenings for airport employees.

Under the perimeter screening program at Logan, Transportation Security Administration workers will assist Massachusetts State Police as they continue to screen employees and vehicles that have access to secure airfield areas via Logan’s north and south gates. Other checkpoints may be added as part of the pilot, which is expected to begin in May, according to TSA spokeswoman Ann Davis.

“The point was to add a deterrent to any nefarious activities that could be conducted between the public and the secure areas and to augment the (employee security) badging program already in place,” Davis said.

Logan also will participate in a second pilot program using biometric access readers to authenticate the identities of employees entering “sterile” airport areas.

Massport and TSA officials will hammer out details in the next 30 days.

The TSA must report to Congress by Sept. 1 on the effectiveness and cost of different employee screening options.
