DOT tanks may only be used for 12 years after the manufacturing date. (This is according to a standard created by the National Fire Protection Association, and adopted as law by most states). Some states may have adopted rules which specify a different period. A dealer in Minnesota claimed that the state only allow 10 years). After that, tanks must be "re-certified", giving another five years (and can be recertified repeatedly, every five years).
I found this additional information. OPD valves are also required on all tanks these days with this exception for Horizontal tanks.
The new OPD (Overfilling Prevention Device) valves will be required on 4 lb. to 40 lb. propane cylinders from 1 April 2002. However, the currently available new valves are designed only for vertical cylinders and cannot be used with horizontal cylinders. Therefore, horizontal cylinders manufactured prior to 1 October 1998 have been exempted from having OPD valves, provided they are so labeled. (Such cylinders manufactured after 1 October 1998 do already have OPD valves).
