BOSTON -- Security at Logan International Airport is about to get tighter.

The Transportation Security Administration, or TSA, is unveiling a new pilot program to screen 100 percent of the airport's employees as mandated by Congress in January.

Boston Airport Tightens Employee Screening Procedures

Logan will be one of seven airports nationally that will take part in the $15 million airport employee screening pilot that will test various kinds of screening procedures over the next 90 days.

The new law requires 100 percent employee screening be evaluated at three airports and alternative screening at four other airports.

Besides Logan, programs will be tested at Denver International, Jacksonville International, Kansas City International, Southwest Oregon Regional and Craven Regional in North Carolina.

NewsCenter 5's Shiba Russell reported that there are two drive-in locations at Logan now where employees and contractors with access to the airfield must stop, get out of their vehicles and be searched by TSA agents with scanners.

"We open their engine compartments. We'll check the contents of the vehicles. We'll assure the manifest agrees with what's on the vehicle," Logan TSA Director George Naccara said.

More than 40 TSA officers will be deployed at the airport to conduct 24-hour searches over the next 90 days.

Months after Florida baggage handlers were accused of smuggling drugs and guns to Puerto Rico, and threats were made against Logan's air fuel depots, Congress ordered the TSA to launch the screening program.

"I know it has been a considered a vulnerability in our airports in particular and we've had a few incidents around the country where we've had some employee access incidents," Naccara said.

Logan is the only airport in the pilot conducting perimeter screening.

"We subject our customers and our passengers to that type of scrutiny and I think it's important that our employees, even though their badged and backround checks have been taken, we want to see that they don't have anything that's prohibitive on their item," said Logan Aviation Director Edward Freni.

Right now, not all airport employees are required to be screened, but the TSA does conduct random searches, inspections and check-point screening for some workers.

"I think we have a good program in place but of course it can always be improved, and if we had infinite resources, we would do a lot more. But we don't have that," Naccara said.

The TSA has until Sept. 1 to submit their findings to Congress.
