Visitors to Hanford, including those on sitewide tours, might need more than a state driver's license as identification to be allowed on the nuclear reservation.
The change is prompted by the READ ID Act passed by Congress in 2005, which has new requirements taking affect Sept. 30.
A grace period is planned from then until Jan. 1 if the visitor is escorted by a Hanford employee with a security badge.
New requirements require that driver's licenses be issued by a state compliant with the REAL ID Act, which does not include Washington.
Acceptable identification is an enhanced driver's license from Washington, a U.S. passport or passport card, a U.S. military identification card or a Washington state driver's license with a second form of identification, including a U.S. Social Security card, an original or certified copy of a birth certification or a voter registration card.
The change will affect visitors to Hanford including subcontractors, delivery drivers, vendors and tour participants, other than those touring only B Reactor.
