An amendment regulating the import of Canadian waste into Michigan landfills has passed the U.S. House of Representatives. The amendment would dedicate $1 million toward enforcing a 1992 treaty that required Canada to notify the U.S. EPA about each shipment of waste that enters the United States. The EPA would then have 30 days to accept or reject the shipment. The amendment, originally approved in July, was folded into a spending package that now must pass the U.S. Senate. Michigan representatives had complained that the EPA had ignored previous requests to implement the treaty. The 30 notification requirement could be used to cause long delays at the border and trigger a crisis for the City of Toronto, sinced not enough permitted capacity exists in Ontario to dispose the waste domestically for anything beyond a short, emergency period. The city currently exports about a million tonnes of garbage to Michigan each year.
