Apples and oranges. New Pier, current regs apply. Old pier, no. However, if your position, relative to the old pier, relative to the new pier, violates the current regs, then clear out.
For example: you could anchor on the NW corner of the old pier on a falling tide and drift over the new pier. Not allowed.
By the same token, you could anchor on theNE corner of the old pier on a rising tide, and be nowhere near the new pier.
All a matter of perspective.
