text: Finally, with regard to our solid waste transportation operations, we are subject to the jurisdiction of the 
  Surface Transportation Board and are regulated by the Federal Highway Administration, OÇce of Motor 
  Carriers, and by regulatory agencies in states that regulate such matters. Various states have enacted or 
  promulgated, or are considering enacting or promulgating, laws and regulations that would restrict the 
  interstate transportation and processing of solid waste. In 1978, the U.S. Supreme Court ruled that a law that 
  restricts the importation of out-of-state solid waste was unconstitutional; however, states have attempted to 
  distinguish proposed laws from that involved in and implicated by that ruling. In 1994, the Supreme Court 
  ruled that a Öow control law, which attempted to restrict solid waste from leaving its place of generation, 
  imposed an impermissible burden upon interstate commerce, and, therefore, was unconstitutional; however, 
  states have also attempted to distinguish proposed laws from that involved in and implicated by that ruling. In 
  response to these Supreme Court rulings, the U.S. Congress has considered passing legislation authorizing 
  states and local governments to restrict the free movement of solid waste in interstate commerce. If federal 
  legislation authorizing state and local governments to restrict the free movement of solid waste in interstate 
  commerce is enacted, such legislation could adversely aÅect our operations.
