(AP) -- Several environmental groups are suing in the ongoing dispute over cruise ships calling in Charleston.

Michelle Sinkler of the South Carolina Coastal Conservation League says details of the suit are being released at a Monday news conference. The South Carolina State Ports Authority and Mayor Joe Riley plan a news conference later to respond.

The cruise industry has expanded during the past year with Carnival cruise lines stationing its Carnival Fantasy ship in the city. The Ports Authority is planning a new $25 million cruise terminal.

Environmentalists and neighborhood residents worry about the impact on the city.

The National Trust for Historic Preservation is expected to announce Wednesday whether Charleston will make the list of the nation's 11 most endangered historic places because of the cruise industry.
