Johnson & Towers, Inc., is in the business of overhauling large motor vehicles. It uses degreasers and other industrial chemicals that contain chemicals classified as “hazardous wastes” under the Resource Conservation and Recovery Act (RCRA)—for example, methylene chloride and trichloroethylene. For some period of time, waste chemicals from cleaning operations were drained into a holding tank and, when the tank was full, pumped into a trench. The trench flowed from the plant property into Parker’s Creek, a tributary of the Delaware River. Under RCRA, generators of such wastes must obtain a permit for disposal from the Environmental Protection Agency (EPA). EPA had neither issued, nor received an application for, a permit for the Johnson & Towers operations. Over a three-day period, federal agents saw workers pump waste from the tank into the trench, and on the third day toxic chemicals flowed into the creek. The company and two of its employees, Jack Hopkins, a foreman, and Peter Angel, the service manager, were indicted for unlawfully disposing of hazardous wastes. The company pled guilty. The federal district court dismissed the criminal charges against the two individuals, holding that RCRA’s criminal penalty provisions imposing fines and imprisonment did not apply to employees. The government appealed. Can employees of a corporation be held criminally liable if their actions on behalf of the corporation violate the federal hazardous waste law?
