COLUMBIA - The environmental board in South Carolina has approved new rules to make it harder for huge garbage dumps to open in the state and import waste from elsewhere.

The State reported that the board at the Department of Health and Environmental Control on Tuesday approved rules to limit how much waste can be brought into South Carolina, and make the approval process more detailed.

A Senate committee is expected to consider the rules Thursday.

Existing rules allow South Carolina landfills to bury as much as 42 million tons of trash annually. The new rules would reduce that to about 11 million tons a year. The newspaper says South Carolina generates only about 5 million tons of trash each year.

The General Assembly is considering a two-year moratorium on new megadumps.
