Dec 05, 2008. /Lesprom.com/. A pulp mill in Pictou County, Canada, has been shut down indefinitely because of leaks in a pipe that carries effluent to a treatment plant, CBC news reported. The problem at the Northern Pulp plant means about 180 employees are out of work. The pipe carries 90 million litres of pulp plant waste daily underneath the East River to the treatment plant at Pictou Landing every day. Environment Minister Mark Parent said the situation is complicated. "They backwashed the system after that and found there were other breaks in the line, so the diver is going down to find out about those breaks," he said. Parent said the plant will remain closed until they can determine how to stop the effluent from flowing into the waterway. The mill produces tissues and toilet paper.
