Okla. Admin. Code § 165:55-13-12.1
A TSP may require a developer desiring an extension to a prospective real estate subdivision to post a surety bond or make a cash deposit or bank letter of credit (at the option of the developer) equal to the estimated total costs of the extension before the construction of the extension is commenced. Total cost of construction shall not include drops to individual users off the telephone distribution facilities. At least annually, for a period of five (5) years, the TSP shall give the developer a credit equal to the percentage which the number of installations made in said twelve (12) months period bears to seventy-five percent (75%) of the total number of installations contemplated by the developer and the TSP for the completed subdivision. The credit referred to in this Chapter, in the case of deposit, shall be returned to the developer annually; with respect to a surety bond posted by the developer, the credit shall be in the form of an annual reduction of the face amount of the surety bond posted. Upon the developer receiving the applicable credit for each installation as set forth in this Chapter, the TSP shall release or cause to be released the obligation of the developer and the surety, if a surety bond was posted; provided, however, if within five (5) years from the date of the surety bond or cash deposit, the proposed development area has not been developed in a sufficient amount for the developer to receive credit for the total cost of extension to the development as agreed upon, then the developer shall be obligated to pay the TSP the total construction costs reduced by all credits previously allowed. In the event that said amount is not paid within sixty (60) days of the date due and a surety bond has been posted, the TSP may declare a default and shall have the right to call upon the surety for payment of the remaining unpaid amount due. In the event of dispute over the circumstances requiring the posting of a surety bond or cash deposit, and/or the reasonableness of the face amount of such bond or cash deposit, a TSP or the developer may apply to the Commission for an appropriate order resolving the dispute.
