There is no fee for the permit and is 100% unenforced (the words of an ABLE agent). The only places that require it are some of the events where you donate and pour your beer - they like to be sure that there are no issues.
I would be interested in the following if remaining:
Picture "C" :
All the 1/2" nipples, both !/2" valves
Picture "D":
1.5 TC with 1/2" MPT - all
1.5 TC with 1/2" FPT - all
Blanks - all
1.5 TC 3/4" FTP
1.5 TC with 1/4" flare - both
TC clamps - all remaining
Thanks
