Normally speaking, Loke, the authorization to dispatch to a destination that is forecasted to be below landing minima at ETA is covered by the proviso of two alternates being available, that meet the alternate filing requirements, and are forecasted to remain so.
Ops specs will then specify the fuel to be carried, and the requirement for dedicated flight following to remain available.
Generally, this provision is granted to an airline after they have demonstrated a favorable operational record, and it is the decision of the principal operations inspector assigned, as to whether this exception to the normally accepted regulations is allowed.
It is not granted lightly.
The specific section to which this exception is allowed is unclear.
A definitive answer could be obtained from an FAA inspector.
It has been quite a long time since I flew for an FAA supplemental carrier and, to the best of my knowledge, only six of the original supplemental carriers were granted this exemption.
