    Disagree. 2 GECs and 1 bonding jumper.

    Meter to rod. GEC
    Rod to rod . Jumper.

    Panel to water. GEC.

    gas pipe

    Adding to this thread, if in the original OP's situation with two ground rods and an GEC to a metal water pipe system can a metal gas piping system in the same house be bonded to a water pipe with #6 copper or does the #6 copper have to go all the way back to the main panel and be bonded there? In any case is this #6 copper a GEC or an EGC?

    A gas pipe is never an electrode. So, no GEC.

    Gas lines may be bonded through an EGC or a bonding jumper. See 250.104(B)

    Sounds like a bonding jumper. If this is CSST some places require that it be bonded otherwise as Jumper stated no additional gas pipe bond is required if it's black gas pipe.

    We have a POCO around here that wants a ground rod connected to the meter enclosure regardless of whatever electrodes you may have connected elsewhere.

    No harm IMO. Just unneeded cost and labor.

    I agree. They can refuse to energize if you don't meet their requirements.
