(a) This compact shall enter into force when enacted into law by any three of the states of Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont. Thereafter, this compact shall become effective as to any other of the aforementioned states upon its enactment thereof.

No withdrawal shall affect any liability already incurred by or chargeable to a party state prior to the time of such withdrawal, and any records, files or information obtained by officers or employees of a withdrawing state shall continue to be kept, used and disposed of only in such manner as is consistent with this compact and any rules or regulations pursuant thereto.
