While San Benito County residents produce an average of 275 tons of trash each day, supervisors have waived a limit of 400 tons per day at the John Smith Landfill in hopes of creating a revenue source by bringing in more trash from other counties. On Tuesday, supervisors agreed to amend a contract with Waste Connections, Inc., that will allow the landfill operator to seek out contracts with other agencies to bring in up to 1,000 tons of trash a day to the location.
