Unfortunately the pipe is state property, CB receives federal funding for the maintenance of the pipe which if needed would be done by the state, however unless there is a posted no trespassing sign and you have a valid fishing license....then fish away! I surf the south side of that pipe regularly and don't remember there being any signs up at all. I don't believe the police have the jurisdictional authority to remove you from the pipe, and a life guard certainly has no jurisdiction...if NC wildlife shows up, you may have a problem. Good Luck.
