Its all different in different regions. In cap city cyclocross you can run disc brakes even though disc brakes are banned by UCI; local events can do what ever they want. Just like SCCA rally-X bans non-production vehicles from competing but we have a local sub. to allow it. if you got on a national SCCA board and asked about kit cars they'd say no way, if you got on the local scca board we'd say cool.
Basically, you asking us about how a local region runs the show doesn't work. You need to ask them. last crit I was at you needed to 'buy' a lic. for $20 before you were allowed to run cat 5 and you had to run 10 cat 5 races before you can move to 4.
