DOE indicates that lot 16 has not had evidence of failure in use and is of an acceptable heat of material.

Accordingly, effective immediately, Condition 1 of the Order prohibiting the use of valves in Superior Valve Company Lots . numbered 16-22 is hereby modified to read:

carrier for transport 48-inch and 30. inch uranium hexafluoride cylinders fitted with Superior Valve Company 1-inch valves manufactured in Superior Valve Company Lots numbered 17 through 22.
