LAFAYETTE, Tenn. -- Almost two months after a tornado destroyed dozens of homes in Macon County, the first FEMA mobile homes have arrived.

The delivery was put on hold when some began questioning the safety of the mobile homes due to the levels of formaldehyde found in some of them.

The first eight of the mobile homes arrived over the weekend. About 40 are expected to be available for those who opt to use them.

There are signs of progress showing where the tornadoes left so much damage.

Jerry Anderson and his family lost their home. Their new one should be ready soon.

"Just, you know, waiting for them to finish it so we can try to get things back together," he said.

In a few days, eight families will be able to move in to the eight mobile homes that are there.

"We will provide as many mobile homes as people apply for and qualify for in Macon County," said FEMA spokesman Jay Eaker.

FEMA and the state of Tennessee put the homes through extensive tests after high levels of formaldehyde were found in some trailers given to Hurricane Katrina victims.

Eaker said the homes in Macon County are safe and optional.

"People don’t have to move into them. They don’t have to accept them. We’re going to provide them with a pamphlet that explains any possible dangers from formaldehyde, and we’ll give them the parts per billions that the particular unit we’ve offered them tested at," Eaker said.

The trailers are still being set up, and residents should be able to move in within the next few days.

The deadline to apply for FEMA aid expires next Monday at 5 p.m. Residents can call 1-800-621-FEMA or click here.
