The National Solid Wastes Management Association (NSWMA) and the city of Dallas have agreed in principle to settle their waste flow control dispute.

The parties have a tentative agreement that doesn’t disturb the U.S. District Court’s permanent injunction decision in October blocking the city’s flow control law, according to court records. On March 14 the Washington-based NSWMA sent the city a proposed final agreement that is currently being reviewed by the city. The Northern District of Dallas court agreed to a deadline of April 26 for two sides to complete the settlement.           

Last October the court ruled that the city violated the Contract Clause of the U.S. Constitution as well as Texas state law and the Dallas city charter with the law it passed in September 2011 directing Dallas waste to go to the city’s McCommas Bluff landfill.

In late November the city moved for a new trial, and the court since has twice extended the deadline in the case.
