20-year contracts for incinerator bonds

["Susan K. Snow" <sksnow@1stnet.com>]

  A retired U.S. Navy man living in Louisiana claims it is illegal for a
  government entity to enter into a contract for 20 years.  I'm told that
  he said that the Navy would have to enter contracts for 5 years with
  options.
  
  The citizens in Southeast Louisiana who are fighting this alleged closed
  loop incinerator wonder who would lend the incinerator company $30
  million with less than a 20 year guarantee.  Does anyone anyone know if
  there is anyway of finding out it 20 year contracts by government
  entities are illegal?
