I ran out of time, so it's not as well formatted as I would like. But at least something is now out there for review. There are a few details omitted in the interest of time and brevity. 

A web formatted version of the my primary comments on the NPRM are here:

I will have a web-formatted version of my "Calibrating the PIR formula" soon.

Feel free to share this with other people who are interested in Natural Gas Pipeline Safety.

Constructive criticism appreciated.

MANY THANKS to those who supported my research, especially the month I spent working on the Salem incident.


May you, and all beings
be happy and free from suffering :)
