Any such agreement may include, but need not be limited to, provisions for the construction, operation, and maintenance of such gas exploration, storage, manufacturing, or transmission facility by any one or more of the parties to such agreement, which party or parties shall be designated in or pursuant to such agreement as agent or agents on behalf of itself and one or more of the other parties thereto, or by such other means as may be determined by the parties thereto. Such an agreement may also include provisions for methods of determining and allocating among or between the parties the costs of construction, operation, maintenance, renewals, replacements, improvements, and disposals with respect to such facility. In carrying out its functions and activities as such agent with respect to the construction, operation, and maintenance of such facility, such agent shall be governed by the laws and regulations applicable to such agent as a separate legal entity, and not by any laws or regulations which may be applicable to any of the other participating parties. Notwithstanding any other law to the contrary, pursuant to the terms of any such agreement, the authority may delegate its powers and duties with respect to the construction, operation, and maintenance of such facility to the party acting as agent; and all actions taken by such agent in accordance with the provisions of such agreement may be made binding upon the authority without further action or approval by the authority;(9) To accept, receive, and administer gifts, grants, appropriations, and donations of moneys, materials, and property of any kind, including loans and grants from the United States government or the State of Georgia or any agency, department, authority, or instrumentality of either, upon such terms and conditions as the United States government, the State of Georgia, or such agency, department, authority, or instrumentality shall impose; to administer trusts; and to sell, lease, transfer, convey, appropriate, and pledge any and all of its property and assets;(10) To invest any accumulation of its funds and any sinking fund or reserves in any manner that the authority considers prudent, including entering into hedging, options, and future transactions, notwithstanding any other law of this state relating to investment of public funds, and to purchase its own bonds and notes;(11) To employ such investment and money-management techniques as the authority shall determine to be prudent and not inconsistent with this article or the other laws of the state;(12) To do any and all things necessary to reduce the cost of gas furnished to political subdivisions contracting with the authority including, without limitation, entering into interest rate swaps and other arrangements for restructuring the authority's capitalization;(13) To provide management, technical, financial, informational, promotional, and educational services to and for the benefit of the political subdivisions;(14) To do any and all things necessary or proper for the accomplishment of the objectives of this article and to exercise any power usually possessed by private corporations performing similar functions which is not in conflict with the Constitution and laws of this state, including: (A) Employment of professional and administrative staff and personnel and retaining of legal, engineering, and other professional services;(B) The purchase of all kinds of insurance, including, without limitation, insurance against tort liability and against risks of damage to property;(C) The borrowing of money for any of the corporate purposes of the authority, provided that obligations of the authority other than revenue bonds for which provision is made in this article shall be payable from funds of the authority other than any special fund allocated to the payment of revenue bonds, and shall not be a charge against such special fund;(D) The power to indemnify and hold harmless any parties contracting with the authority or its agents from damage to persons or property; and(E) The power to act as self-insurer with respect to any loss or liability; and(15) To issue its revenue bonds as provided in this article in evidence of its indebtedness incurred with respect to the powers described in this article, such bonds to be payable from the revenues, receipts, and earnings of the projects or systems of the authority and other available funds thereof; to execute trust agreements or indentures; to sell, convey, pledge, and assign any and all of its funds, assets, property, and income as security for the payment of such revenue bonds; and to provide for the payment of the same and for the rights of the owners thereof.(b) Notwithstanding any other provision of this article, the authority shall not have the power or authority to engage in the distribution or sale of gas or the transmission of gas to an ultimate consumer thereof, irrespective of whether such consumer is a public or private person or other entity, and irrespective of whether the authority acts alone, in conjunction with, on behalf of, or as an agent for another or others in any such transaction.
