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 related services. 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 approval from the county's electors.

Additionally, the act stipulates that the authority must enter into contracts with history museum services providers to ensure that funds are used exclusively for supporting history museum services. It mandates that the authority conduct its business in compliance with open meetings and freedom of information laws, and requires annual audits to ensure financial accountability. The act also includes provisions for the election process related to tax levies, reimbursement of election costs, and the authority's financial management, including budget preparation and deficit correction plans.
