Select “Update Metering Agent Contacts” under the “Submit Online Change of Information” header. Select the name of the metering agent requiring an update. You will see their existing contact information listed. Make necessary changes, then select a contact type and save the data. A screen will appear with a comparison of old and new data so you can verify.

If you need to render an agent inactive, click the “Inactive” button. A warning will appear, prompting you to verify the inactivation.
