If you are the Navy, and you have tons of old warships it would be natural to look at reefing to save disposal costs. But what happens when cleaning up the mess is too costly? Just strongarm the EPA into giving you a permit to dump your PCBs at sea! If you don't think PCBs are bad in the ocean, just do a google search on the chemical...it will scare you. You certainly won't catch us eating any seafood caught near the Oriskany!
