AIKEN, S.C. -- The agency in charge of watching over South Carolina's environment is holding a public meeting to discuss a large potato farm in Aiken County.

The Department of Health and Environmental Control will host a discussion Tuesday at 6:30 p.m. about Walther Farms, which has received permission to draw up to 9 billion gallons of water from the South Fork of the Edisto River.

DHEC says the meeting is a courtesy to residents because public meetings on large water withdrawals are not required under a recently passed state law.

Opponents of the 3,700-acre potato farm say allowing it to withdraw that much water from the river could increase pollution and deplete the amount of water going into a Lowcountry nature preserve.
