(3) any other provision of law enacted on or after November 16, 1990, that specifically replaces such a map or authorizes the modification, revision, or correction.

#### (b) System maps

At least once every 5 years, the Secretary shall review the maps referred to in subsection (a) and shall make, in consultation with the appropriate State, local, and Federal officials, such minor and technical modifications to the boundaries of System units as are necessary solely to reflect changes that have occurred in the size or location of any System unit as a result of natural forces.

#### (d) Additions to System

The Secretary may add a parcel of real property to the System, if—
