Tenn. Code Ann. § 65-28-205: Rates and charges - Regulation

The rates and charges for transportation by pipeline of landfill methane, either alone or in combination with natural gas, and the construction of facilities for the transportation by pipeline of landfill methane, whether alone or in combination with natural gas, shall be subject to the jurisdiction of the Tennessee public utility commission to the same extent as the rates and charges, and the construction of facilities for, pipeline transportation of natural gas. No person that is exempt from regulation by the Tennessee public utility commission in the transportation of natural gas shall become subject to such regulation by operation of this section or the transportation by such person of landfill methane, either alone or in combination with natural gas. No person shall be required to transport landfill methane by pipeline in combination with natural gas, if the landfill methane tendered for transportation does not meet quality specifications reasonably required by such person for pipeline transportation of natural gas. The Tennessee public utility commission shall expedite the disposition of any proceeding brought concerning any rate, charge, or construction of facilities for transportation by pipeline of landfill methane.
