NEW ORLEANS -- A judge in Louisiana has ordered FEMA to submit a “detailed plan” for testing air quality in government-issued trailers used by Gulf Coast hurricane victims.

Katrina and Rita slammed parts of the Gulf coast in 2005.

U.S. District Judge Kurt Engelhardt says FEMA and administrator

David Paulison have until December 17^th to respond to court papers filed by a group of trailer occupants.

They want the air-quality tests to begin immediately.

Engelhardt issued the ruling last week. The judge also ordered

the Federal Emergency Management Agency to have a FEMA lawyer attend a January 18^th hearing on the matter.

On November 2^nd, federal scientists were scheduled to start testing FEMA trailers in Mississippi for levels of formaldehyde.

But FEMA postponed those tests—saying it needed more time to prepare.

FEMA says the tests are expected to begin soon.
