Georgia Code Title 46. Public Utilities and Public Transportation § 46-4-82

(a) There is created a public body corporate and politic to be known as the Municipal Gas Authority of Georgia, which shall be a public corporation of the State of Georgia and which shall have perpetual existence. The authority, however, shall not be a political subdivision of the state but shall be an instrumentality of the state, a mere creature of the state, having distinct corporate entity and being exempt from Article 2 of Chapter 17 of Title 50.

(b) The authority shall have its principal office either in Fulton County or in a county contiguous to Fulton County. The authority's residence for the purposes of this article shall be either Fulton County or such other county contiguous to Fulton County. If the authority designates a county other than Fulton County as its principal office, notice of such designation shall be given in writing to the Secretary of State and the address of such designated office shall be available for public inspection in the office of the Secretary of State.
