Turns out some 36 sunken vessels are deemed to be a potential threat of oil along the coast of the USA, with 17 being recommended for further assessment and potential removal of both fuel oil and oil cargo. You might wonder why NOAA haven't just removed all of these vessels. In their defence there are over 20,000 wrecks dotted around the coastline. And it isn't just a case of having the funding to remove them all, it can be technically challenging to remove them safely.
