Estimated amount spilled reported by refinery is between 42 and 420 gallons. LDEQ reported 100 gallons spilled. The total amount of inhibitor originally contained in the ballast water was less than 14 lbs. = 4 lbs sodium nitrate, 0.14 lbs sodium hydroxide. After 7 years these compounds would most likely be inert.
