Approval means a determination by the Administrator that a State rule, program, or requirement meets the criteria of 63.91 and the additional criteria of either 63.92, 63.93, 63.94, or 63.97 as appropriate. For accidental release prevention programs, the criteria of 63.95 must be met in addition to the criteria of 63.91. This is considered a full approval for the purposes of this subpart. Partial approvals may also be granted as described in this subpart. Any approved requirements become applicable requirements under 70.2 of this chapter.
