Scrap yards in Kentucky would be barred from paying cash for copper and other recyclable metals under legislation that cleared the state Senate Wednesday. The measure requires people selling scrap metal be paid by a check sent by mail. That move could give police names and addresses if the metals are later found to be stolen. The Senate voted unanimously for the bill, which now returns to the House for final passage. Bill sponsor Democratic state Representative Tanya Pullin says thieves have taken guardrails, manhole covers, catalytic converters, utility lines, and even rooftop air conditioning units. Nationwide, copper thefts are estimated to cost businesses $1 billion a year.
