The final phase-out date for all single-hull tank vessels and all single-hull tank vessels with double sides or double bottoms, 46 USC 3703A, to operate carrying oil in bulk in U.S. waters, including the Exclusive Economic Zone, is  1st January 2015.

Only double hull tank vessels of 5000 gross tons and above, and delivered after 31st December1986, are permitted to operate in U.S. waters after 1st January 2015.

The remaining 93 tankers under OPA-90 rules are phased out between 2000-2005, 2010 and 2015. It is possible that several vessels can be extended beyond 2015 by reason of being double hull even though they will be in excess of 35 years of age. The phase-out is as follows:
