It sounds like you're referring to "47 CFR § 90.267 - Assignment and use of frequencies in the 450-470 MHz band for low power use". The industrial/business pool allocations in this subsection are in Group C and Group D. " The Industrial/Business Pool frequencies in Group C are available nationwide for non-coordinated itinerant use..." while those in Group D require coordination.

N9UPC,this next part isn't directed specifically at you. I'm putting it here for folks who find this thread in the future, since this is a recurring topic.
Here's some friendly advice for anyone trying to handle licensing on their own for the sake of saving money from someone who's been through it.
Read Part 90. You can skim through subsections that clearly don't apply to you, but since you'll be responsible for following the rules that apply your license, you really ought to know what they are. Reading the rules before you apply for your license will answer many of your questions. It will inform you of things you didn't know you could do, and things you didn't know you
couldn't do. No, Part 90 isn't exactly "beach reading." If you're just starting out in radio, you might have to look up some unfamiliar terms and learn to decode emission designators, but for the most part, it's clear and easy to understand.
By the time my license was approved, I had a pretty good understanding of the rules, but I certainly didn't start that way. Save yourself the time, aggravation, and all the back-and-forth with the FCC by getting it right the first time.
