Legal technicalities of which you may or may not want to be made aware:

1) I would avoid face-to-face confrontation with all public officials
and under no circumstances would I dispute any of their assertions except
in writing. If they brought criminal charges of your threatening them,
the courts would believe them irrespective of the facts. "You are in bear 
country" and bears do not resort to due process before eating you.

2) Mr. Pucci's "compromise offer" entailed repeat inspection BEFORE any
work was done. I would proceed on the assumption that such an inspection
will in fact be scheduled. It would be very much to our advantage, because
the findings would almost certainly differ from the Ciamataro inspection
of 2011. You have a right to a written inspection report. It's your call, 
whether or not you request a written inspection report. Arguably the
requirement to document would lead to exaggeration, but it also buttresses
your legal position, whatever such buttressing is worth. From a legal
perspective, a repeat inspection supersedes and technically reverses the
Appeals Courts affirmation of the 2011 order that the entire system be
destroyed.

3) Therefore my advice is that you try to hire a plumber a) to get a permit,
and b) to participate in a new inspection before c) he then makes the 
necessary repairs.
