COLUMIBA — Conservation groups and county governments are fighting legislation they contend will lead to more out-of-state trash being dumped in South Carolina, polluting both the environment and the senses.

But business groups argue the proposal does no such thing. They contend the bill that bans counties from requiring disposal in their landfills is about ensuring businesses have a choice of where they dump their trash.

The debate will pick up in the Statehouse when the Legislature returns in January. The bill moved quickly through the House earlier this year but got hung up in the Senate.

In an effort to stop it from going further, a coalition that calls itself Don’t Dump on SC launched a statewide campaign of radio and TV advertisements Monday that will run for the next month.
