When power, other than economic development power, becomes available for long-term allocation to industrial customers, pursuant to section 460.1(a) or (b) of this Part, or when the trustees determine that circumstances warrant a prospective allocation of such power on an “as available” basis, further applications for such power or for prospective allocation shall be solicited by public notice. Notice shall be in the form of newspaper advertisements, press releases and/or by such other means as the trustees find appropriate. Notices and advertisements shall make reference to the allocation criteria set forth in this Part. The New York State Department of Economic Development shall be contacted to assist in attracting suitable applicants from within and without the State. Specific notice of any available replacement power shall also be given to existing replacement power customers under the terms of the 1982 replacement power settlement agreement.
