State Tries to Regulate Ships' Fuels?

One bill (HB2919) proposed for this session of the Hawaii Legislature purports to regulate the use of bunker fuel on ships in Nawiliwili Harbor on Kauai.  The background is discussed here.

Haven't fully digested yet, but the State of Hawaii only extends out three nautical miles, so any attempts to regulate shipboard operations (i.e. five mile radius in the bill) is problematic.
