The proposed "History Museum Authorities Act" establishes a framework for counties in Michigan to create history museum authorities. These authorities will serve as public corporate bodies with the power to support and provide funding for history museums and local historical museums within their jurisdiction. The act defines key terms such as "history museum," "local historical museum," and "history museum services provider," and outlines the process for establishing an authority, including the preparation and adoption of articles of incorporation by the county board of commissioners. The authority will have the power to levy a tax of up to 0.2 mills for a period of ten years, contingent upon voter approval, to fund history museum services.

Additionally, the act mandates that any contracts with history museum services providers must ensure that funds are used exclusively for providing services to history museums. It also stipulates that the authorities must conduct their business in compliance with open meeting laws and the Freedom of Information Act. The act requires annual audits and adherence to budgeting standards, ensuring transparency and accountability in the management of funds. The implementation of this act is contingent upon the passage of two other related bills in the legislature.
