(1) A vessel that has a single hull may not operate after January 1, 2010, and
(2) A vessel that has a double bottom or double sides may not operate after January 1, 2015.
Double sides and double bottoms must meet the requirements in § 157.10d(c) or (d), as appropriate. A vessel will be considered to have a single hull if it does not have double sides and a double bottom that meet the requirements in § 157.10d(c) and § 157.10d(d). To determine a tank vessel's double hull compliance date under OPA 90, use the vessel's hull configuration (i.e., single hull; single hull with double sides; or single hull with double bottom) on August 18, 1990. The conversion of a single hull tank vessel to include only double sides or only a double bottom after August 18, 1990, will not result in a change of the vessel's originally scheduled phase-out date. The conversion of a single hull tank vessel to a double hull tank vessel meeting the requirements of § 157.10d complies with OPA 90.
