Section 66-F - Purchase and procurement of natural gas at lowest available price1. The commission shall have the authority to direct any gas corporation subject to the jurisdiction of the commission to purchase or procure natural gas at the lowest available price as determined by the commission.2. A gas corporation shall be required to purchase supplies of natural gas whenever a natural gas producer provides the gas corporation with at least six months prior notice of the availability of such gas, and the delivered cost of such gas is equal to or less than the highest delivered cost of natural gas produced outside the state which the gas corporation would otherwise purchase or acquire, adjusted to reflect substantive differences, if any, in the terms and conditions applicable to the sale of such gas over the period of availability of the natural gas; provided, however, that no gas corporation shall be required to purchase natural gas where it can demonstrate such purchase would have an adverse impact upon its ratepayers, which cannot be reasonably mitigated.3. A gas corporation shall respond to a notice of availability of supplies of natural gas at a specified delivered cost provided by a producer of such gas within one month of the receipt of such notice, and, if it indicates its intent not to purchase such supplies, shall provide in detail its reasons therefor. A natural gas producer may petition the public service commission, within fifteen days of the receipt of a gas corporation's response, to order such gas corporation to comply with subdivision one of this section. Such petition shall contain sufficient information to demonstrate the petitioner's ability to provide the supplies of natural gas offered for sale to the gas corporation. A copy of such petition shall also be served upon such gas corporation. Within twenty-one days of the receipt of such a petition, a gas corporation shall file such information as is necessary to demonstrate that the purchase of natural gas during the period of availability at the specified delivered cost of such gas would have an adverse impact upon its ratepayers. The petitioner and others shall have the opportunity to comment upon the filing by the gas corporation within twenty-one days of such filing. The commission shall take final action on any such petition within forty days after the date upon which the petitioner's comments are due. The commission may require a gas corporation to purchase all or a portion of the supplies of natural gas offered by the petitioner during the period of availability at the specified delivered cost, or at such other cost as will not result in an adverse impact upon such gas corporation's ratepayers. Nothing in this section shall require a producer of natural gas to sell such gas to a gas corporation at a cost other than that specified in its notice of availability.N.Y. Pub. Serv. Law § 66-F
