As several Charleston organizations with concerns about the cruise ship business await S.C. Supreme Court action on their lawsuit against Carnival Cruise Lines, they are continuing to press their case on other fronts.

The Historic Ansonborough Neighborhood Association, Charlestowne Neighborhood Association, The Preservation Society of Charleston and the Coastal Conservation League -- the groups suing Carnival -- were joined Monday by The Committee to Save the City and Charleston Communities for Cruise Control in calling for an independent study of the location the State Ports Authority has chosen for a new cruise passenger terminal.

The SPA plans to begin construction this year on a $35 million terminal, using an existing warehouse at Union Pier near Laurens Street, where there were previously cargo operations.

The terminal, which was the subject of numerous public meetings last year, would replace an older one at the south end of Union Pier, near Market Street.

Opponents have suggested cruise ships should dock elsewhere, such at Columbus Street Terminal or Patriot's Point. SPA President Jim Newsome has called that idea "a non-starter."

Port officials have said Columbus Street Terminal, where $23 million was recently invested in capital improvements, is not an alternative, and is a focal point of the SPA's growing non-container business. A spokeswoman said the SPA had nothing new to add in response to the latest call for an independent study.

The Charleston Communities for Cruise Control organization, which calls itself C4 for short, also has asked Carnival to voluntarily agree to standards addressing "the size of ships, frequency of visits, air and water emissions, fuel used, noise mitigation, impact fees, local purchasing and periodic reporting on the standards."
