The Hampden mail processing facility will stay open if a postal reform bill passes in the U.S. Senate and becomes law. In February the postal service announced plans to stop processing mail in Hampden, shifting its work to a mail plant in Scarborough as a way to save money. More than 180 people work at the Hampden plant. Senator Susan Collins put language in the reform bill that would keep the Hampden plant open. “What the bill does is establish certain service standards for overnight delivery and for the postal service to abide by those standards it needs a plant both in southern Maine, the Scarborough plant and the plant in Eastern Maine, the Hampden plant,” said Senator Susan Collins. Senator Collins says if it passes it could also help keep 100 other plants across the nation open. She’s hopeful it will pass in the Senate on Wednesday.
