Approved CES and BON

Dear all,
The CGFNS has just approved my CES-that I meet all progamme requirements, but I contacted PCS the organisation authorised by the Mass. state BON I want to register about my ATT, they are saying they need to consult the Mass BON for direction because my Uni at UK did not break my hours into various nursing areas as required, here is my questions:
1. Can the BON refuse to give ATT even the CGFNS has approved me?
2. If they can refuse to give ATT what other options are available?
3. What other states BONs are straight forward to approach?
4. What state BONs offer onlinre aplication.
Time is of essence now as I cannot afford to wait any longer.It took about 10 months to get the CES,and I feel I cannot wait any longer to get my ATT.

Thank you all.
