    Regulatory? In what sense? Local building codes  ARE regulations.

    Hmm, sounds a little paranoid but I doubt it.  Windspeed ratings are 
based on local conditions and industry standards. All  3074 county windspeed 
ratings are in the TIA-2222 Tower Standard but the  building department can upgrade 
it if they see fit. 
 
    Yes, it's a SAFETY issue.

Yes. The MA-series is NOT the right tower  for the job. Time to make another 
selection.
