The dedicated clean ballast tanks or equipment on a tank vessel that has a letter issued under [§ 157.204](/cfr/33/157.204.md) may not be altered so that they no longer meet the plans accepted under that section unless:

- (a) The owner or operator of that vessel submits plans that show the alterations to the Coast Guard official to which the plans were submitted under [§ 157.200](/cfr/33/157.200.md) or [§ 157.202](/cfr/33/157.202.md);
- (b) The owner or operator of that vessel submits changes to the manual under [§ 157.224](/cfr/33/157.224.md) that show and describe the alterations to the Coast Guard official to which the manuals were submitted under [§ 157.206](/cfr/33/157.206.md) or [§ 157.208](/cfr/33/157.208.md); and
