Michigan's U.S. senators say the years-long practice of allowing Canadian municipal trash to roll into the state has come to a close.
Democrats Debbie Stabenow and Carl Levin announced Monday they've been given assurances that Ontario officials will honor an agreement the sides negotiated four years ago to stop shipments of city waste to Michigan as of Dec. 31, 2010.
The lawmakers say the agreement prevents more than 40,000 trash trucks from entering the state and stops 1.5 million tons of waste from being dumped here.
Levin says there is more work to do, however. Trash from private companies will continue to enter the state.
Michigan residents complain that trucks carrying Canadian garbage cause environmental and health problems and clog their roads.
