Madawaska Paper Mill, Maine

The Madawaska Mill, also known as the Twin Rivers Paper Plant, is really one facility, split by the international boundary. Pulp is made on the Canadian side of the river, and pumped to the US side to be turned into paper, a system that avoided the tariff for importing paper into the US.  Steam is also generated on the Canadian side, where fuel costs used to be lower, and pumped to the US plant. A total of seven pipelines connect the plants in lines running over and under the river. The plant is one of just a few businesses that straddle the international border. It is one of a half-dozen or so major paper plants still operating in Maine.
