*   Please enroll me in the Average Payment Plan. I do not have a past due balance and there is at least 6 months of billing history at this address. I will pay all future bills on or before their due date. I understand my monthly bill is based on a 12-month rolling average of my natural gas bills and that Oklahoma Natural Gas will make necessary adjustments to my average payment amount each month based on the balance of my account.
