The ubiquitous T-shirt, billboard of the masses, has made an appearance at the Environmental Protection Agency, where employes apparently are taking advantage of the agency's new, open atmosphere to wear their opinions on their chests.

The latest entry bears the legend "I Survived the Ice Queen's Acid Reign," a reference to former administrator Anne M. Burford, who earned the sobriquet for her aloofness.

On the other side, the shirt has a list of political appointees who have left the agency in recent months, along with a quote from Burford: "Doing more with less."

Burford isn't the first administration official to be honored over the breeches. A T-shirt designed by Interior Department wags, which featured a dead buffalo as a representation of the policies of Secretary James G. Watt, was an instant hit a couple of years ago among some disgruntled Interior employes.

A softball team from the Justice Department's Civil Rights Division, where scores of attorneys once signed a petition protesting the administration's civil rights policies, has T-shirts labeled "Justice Dissidents."

EPA employes say their shirt, which originated in the agency's Denver regional office, is a hot item among the agency's career staff, and its popularity has spread to other quarters as well.

"We've had requests from the Hill and the White House, usually through some other organization," said Mike Burns, an employe in the EPA's hazardous-waste division. "I guess they don't feel comfortable just calling up and asking for one."
