More than 6 million, two rods are required unless you can prove one meets 25 ohms or less. That still doesn't change the requirement that all electrodes present must be used and I didn't see anything in your link that said anything different. Are you saying your POCO is the "electrical inspector", if you are they must inspect to applicable codes.
The first sentence of 250.50 says
Our utility requires two ground rods at the meter, no mater what other grounding electrodes are connected to the system. They do not have a 25 ohm rule. If you want the power to be connected, you will provide two ground rods and connect the GEC from those ground rods in the meter can. They specify that all other GECs be connected in the service equipment.

The local inspectors can't write a violation for this, but they will advise the contractor at the time of inspection that without the two ground rods at the, the utility will not connect the service.

To answer the OP the inspectors that require both rods and cee we don't know if they are right or wrong.

...

Stop creating confusion. They are wrong under the NEC, and the OP didn't mention anything about utility requirements. Many utilies have no such stupid requirements.
Moreover, with respect to the second part of the OPs question, an inspector requiring the disconnection of already-installed electrodes is an NEC violation no matter if the utility has special requirements or not.
