The Federal Energy Regulatory Commission (FERC) provided a notice about receiving communications that are not part of the official decision-making process. According to rules, such communications must be recorded and may be considered for inclusion in the decision-making process if deemed fair. Both prohibited and exempt communications are handled differently: prohibited ones are usually kept separate, while exempt ones are included unless made with a cooperating agency. A list of recent communications can be viewed on FERC's website.
Simple Explanation
The Federal Energy Regulatory Commission (FERC) is telling people that when they talk about something important without it being officially recorded, they make sure to write it down in case it needs to be considered. Some talks are okay to include, and some are not, depending on the rules. If you're curious, you can find a list of these talks on their website.
