The plan was made public Thursday in a federal report sought by Congress, which asked the administration to determine the safety of the eradication program for humans and the environment. An examination of the spraying program uncovered no unreasonable risks in either category, said a senior official who briefed reporters on condition of anonymity. The report was a collaboration by the State and Agriculture departments and the Environmental Protection Agency. Eradication of coca plants in Colombia has been a U.S. goal for more than two years. The aim is to cut cocaine exports to the United States and deny financing to illegal armed groups that profit from the drug trade. They include two leftist rebel groups and a rightist paramilitary organization. Sen. Patrick Leahy, D-Vt., chairman of a Senate panel dealing with spending on foreign operations, has been concerned about potential hazards of the fumigation program and is the author of legislative conditions on paying for it. On Thursday, Leahy declined to take a stand on the study but noted there are reports of health problems and food crops destroyed from the fumigation. "Spraying a toxic chemical over large areas, including where people live and livestock graze, would not be tolerated in our country," Leahy said. The study contains an Aug. 14 letter to Secretary of State Colin Powell from Agriculture Secretary Ann Veneman, who defended the use of glyphosate, the main herbicide in the spraying. She wrote that glyphosate "poses minimal health risks to humans and animals, is environmentally benign, and degrades rapidly in soil and water." But a memorandum in the report says an inert ingredient in the glyphosate formulation used in Colombia carries the potential for acute eye toxicity, which can cause temporary discomfort. The report said the EPA concluded that the risks of eye damage are limited to the handlers and mixers of the concentrated formula and not the public at large. A test sponsored by the State Department determined that the spray mixture had a toxicity level of three on a scale of one to four, with one being the most toxic. A new formulation with lower potential for toxicity was recently approved for use in Colombia. The report said the State Department expects to place an order for the product early this month. Some people living in areas where spraying occurs have complained of health problems from the fumigation but the Colombian government says it has found no evidence to support such claims. Colombian officials say the herbicides used by coca growers are more unsafe than glyphosate, which is widely used in the United States. - --- MAP posted-by: Terry Liittschwager
