Mark Oldfield with "Cal Recycle" says anyone with more than 25 pounds of aluminum cans or plastic bottles or 250 pounds of glass must stop for an inspection.
"We did a pilot study at border inspection stations to document trucks coming across with loads of beverage container material," says Oldfield. "Based on that three-month study, we estimated that somewhere in the range of $30 million or somewhat more could potentially be coming into the state being claimed for illegal redemption each year."
A driver must tell an inspector where the material is going and keep a copy of the inspection.
The change is one of several that Cal Recycle hopes will save the fund $130 million dollars per year by 2017.
