COLUMBIA — Gov. Nikki Haley is planning to discuss a state agency’s handling of an environmental permit for a Georgia port expansion.

The Republican is scheduled to hold a news conference today at the Statehouse in Columbia.

Haley’s office says the governor is discussing the Department of Health and Environmental Control board’s decision to approve a water quality permit required to expand Savannah’s port operations.

DHEC initially planned to reject the Savannah River dredging permit. But Haley has said Georgia came back with an agreement to meet South Carolina’s rules, including a 50-year commitment to maintain wetlands and control dissolved oxygen levels along the river.

Last week, Haley told senators she would not appear at a hearing to answer questions about the board’s decision.
