Tennessee Code Title 9. Public Finances § 9-21-903

(a) Prior to the adoption by the governing body of the resolution authorizing the issuance of general obligation refunding bonds, a plan of refunding shall be submitted for review to the comptroller of the treasury or the comptroller's designee, who shall immediately acknowledge receipt in writing of the proposed plan of refunding. If the sole purpose of the plan of refunding is to provide cost savings to the public, a computation of projected cost savings shall also be submitted to the comptroller of the treasury or the comptroller's designee as a part of the plan of refunding. The comptroller of the treasury or the comptroller's designee may report thereon to the governing body within fifteen (15) days after receipt of the plan. After receiving a report of the comptroller of the treasury or the comptroller's designee on the plan of refunding or after the expiration of fifteen (15) days from the date the plan of refunding is received by the comptroller of the treasury or the comptroller's designee, whichever date is earlier, the governing body may take such action with reference to the proposed plan of refunding as it deems advisable in accordance with this part.

(b) If the sole purpose of the plan of refunding is to provide cost savings to the public and if the state funding board has established guidelines with respect to such cost savings, the comptroller of the treasury or the comptroller's designee shall determine whether the plan of refunding substantially complies with the guidelines, and shall so state in the report on the plan of refunding. After receiving a report of the comptroller of the treasury or the comptroller's designee stating that the plan of refunding complies substantially with such guidelines or after the expiration of fifteen (15) days from the date the plan of refunding is received by the comptroller of the treasury or the comptroller's designee, whichever date is earlier, the governing body may take such action with reference to the proposed plan of refunding as it deems advisable in accordance with this part.

(c) If a report of the comptroller of the treasury or the comptroller's designee states that the plan of refunding does not substantially comply with the guidelines, if any, a notice in substantially the following form shall be published prior to the sale of such bonds once in a newspaper having general circulation in the local government:
