Was it applied for Derver DOL (regional) or Colorado SESA (state)? From what I'm reading, It's being applied for Colorado SESA.
Ask your Attorney, what is the rational for converting to RIR? Keep in mind that a) Convertion will take couple month and b) once converted, a significant risk is added to the case.
