At the risk of further strengthening the impression that this has become the Lew Folkerth Blog, I want to mention that I just read an excellent presentation by Lew (who is with RF, of course) on complying with CIP v5 for Low impact assets. He gave it in August, but I just got around to reading it yesterday.
If you have Lows - and especially if you have only Low impact assets - I highly recommend this. It takes great pains to gather into one place everything you need to be considering and doing.
You can find the presentation on this page. Under "Seminars / Workshops", click on "Open Compliance Call 8/17/2015" and click on the second PDF file.
