(Portland, OR) -- The Portland and Western Railroad has been fined 81-thousand dollars by the Oregon Department of Environmental Quality for a train derailment near Corvallis in January. The railroad's trestle over the Marys River failed, sending almost 200-tons of urea into the river over a period of nine days. The DEQ says the fertilizer breaks down into ammonia and can be toxic to aquatic life. State officials say they are concerned about the condition of Portland and Western's other river crossings. The railroad can appeal the civil penalty.
