The Clinton administration is preparing to implement a flurry of controversial regulations on environmental and other issues before a new president moves into the White House on 20 Jan. The U.S. EPA alone is said to be considering more than 60 new regulations, including ones to restrict or ban the use of certain pesticides and crack down on emissions from heavy-duty diesel trucks and buses. Another regulation in the works would refuse to give federal contracts to companies that have violated environmental, labor, or health laws. And the Department of Agriculture is working to complete a set of national standards for organic foods.
