destruction - Permanent copies maintained.

All warrants or checks issued by the Commission for Human

Services and the State Treasurer, in payment of assistance to the

needy, aged persons, blind or dependent children, shall be

microfilmed or duplicated in a manner acceptable to the Archives and

Records Commission, provided further that the Department of Human

Services is hereby authorized and directed to destroy said warrants,

by burning, shredding, chemical process or any other method which

will insure the complete destruction thereof, after microfilm or

other copies are made thereof. Any redeemed warrant or check that

has been microfilmed, imaged or duplicated in a manner acceptable to

the Archives and Records Commission shall be destroyed after a

period of time consistent with banking industry standards for

checks. The Archives and Records Commission, with the assistance of

the State Treasurer, shall survey financial institutions to

determine the industry standard for retention of paper checks after

they have been duplicated in a manner consistent with federal law

and industry practice. Such survey shall include the industry

standard or federal law for retention of duplicated checks.
