Forest, If you look at the aboveground contractors' acceptance form from 13 it has a question as far back as I can remember asking about whether there is a coupon recovery procedure. I believe the meaning is kind of like for an operating room where all the tolls, sponges, bandages, etc. are identified and counted going in and coming out. The form wants to know if you have a method for making sure there are the same number of coupons as there are holes. You can count them and the number of holes, attach them at each tee, put them all together in a box and make them part of the as-builts, you could flush each section of pipe, you could send a camera down every line in the system--you just need to have a system (key word) for knowing there aren't any coupons forgotten in the pipe. Obviously in your example there was no system, an inadequate system, or just a mistake. I've never been comfortable around someone who says, "Don't worry, it's not loaded." He and I are coming from a fundamentally different mindset.
