at least the 2012 act requires them to allow flying UAS for commercial purposes (at the very least in the arctic, and likely elsewhere, depending on how you read it), and start a rulemaking about it
The 2012 act requires that the FAA have rules in place by 2015. So far, the FAA has missed nearly every deadline that was required by the 2012 act.
In theory, the FAA's funding is contingent upon having rules in place. In practice, I'm sure congress will grant them an extension when they end up late.
