A ship carrying toxic waste from U.S. military bases in Japan is likely to meet with controversy when it docks later today in Seattle. The 90 tons of PCBs had been en route to Vancouver, Canada, but the Canadian government abruptly rescinded a permit for the waste to be unloaded, a U.S. EPA spokesperson said last night. Now the U.S. Department of Defense and the EPA have begun hasty negotiations to figure out what to do with the toxic load. The waste was supposed to be trucked to a processing plant in Ontario owned by Trans-Cycle Industries, but the company has yet to get the necessary permits. Environmental groups in Seattle and Vancouver are fighting to keep the shipment away from their cities.
