I have a BTF bumper that is about the same width. It has passed inspection 5-6 times without question. Last time he flagged it as being too narrow. My solution was to weld some sections of reciever inside/behind the bumper that were multi-purpose for tow points. Then I created a street legal bumper that could also slide into those reciever points. It is ugly, but since it attaches with pins, it was signed off as being legal. Now I have a Utah legal bumper that can be installed or removed as needed.
