Number: RL34043 Title: Interstate Shipment of Municipal Solid Waste: 2007 Update Authors: James E. McCarthy, Resources, Science, and Industry Division Abstract: This report provides updated information on interstate shipment of municipal solid waste (MSW). Concerned about increased waste imports, some states have attempted to regulate this commerce, by imposing barriers or requirements specific to waste importation; federal courts, however, have declared such state restrictions unconstitutional. If states are to have such authority, these decisions say, congressional action is required. Since the late 1980s, Congress has considered, but not enacted, numerous bills that would grant such authority. Over this period, there has been a continuing interest in knowing how much waste is being shipped across state lines for disposal, and what states might be affected by proposed legislation. This report provides data useful in addressing these questions. Pages: 27 Date: Updated June 13, 2007
