"We still have containers of vinyl chloride. We're taking all precautions to make sure the community stays safe. As long as we have vinyl chloride and the potential for that release, we're being very cautious for public safety purposes," added Coast Guard Captain Todd Weimers.

Weimers says they have started pumping out the remaining tankers of vinyl chloride but "we don't know how long that is going to take because we don't jknow what the consistency of the material that is in the container," Weimers said.

Public schools will be open on Monday, but a day care center and the municipal courts will be closed.
