(a) As used in this Code section, the term: (1) ‘‘Subrecipient’’ means an entity that receives a grant of state funds from the Governor’s emergency fund or from a special project appropriation through a local government and shall also mean an entity which in turn receives all or any portion of such grant funds from a subrecipient. (2) ‘‘Unit of local government’’ means, for purposes of this Code section and notwithstanding paragraph (16) of Code Section 36-81-2, a: (A) Municipality, county, consolidated government, county school district, independent school district, other political subdivision of the state, any public agency or authority of any of the foregoing, or any combination of any of the foregoing; (B) Regional commission; (C) Public authority created by local Act or local constitutional amendment of the General Assembly; or (D) Public authority created by general law which applies to an area of less than the entire state and which requires activation by a county or municipal government. (b) Each grant of state funds to a recipient unit of local government from the Governor’s emergency fund or from a special project appropriation in an amount greater than $5,000.00 shall be conditioned upon the receipt by the state auditor of a properly completed grant certification form. The form shall be designed by the state auditor and shall be distributed with each covered grant as required by this Code section. The grant certification form shall require the certification by the recipient unit of local government and by the unit of local government auditor that the grant funds were used solely for the express purpose or purposes for which the grant was made. Such form shall be filed with the state auditor in conjunction with the annual audit required under Code Section 36-81-7 or 50-6-6 or any other applicable Code section for each year in which such grant funds are expended or remain unexpended by the unit of local government. A recipient unit of local government which is not otherwise subject to the annual audit requirements specified in this subsection shall file a grant certification form with the state auditor no later than December 31 of each year in which such grant funds are expended or remain unexpended. For grant funds to subrecipients, the certification by the unit of local government auditor required by this subsection may also be made by an in-house or internal auditor of the unit of local government who meets the education requirements contained in subparagraph (b)(3)(A) of Code Section
