This bill establishes a new chapter, Chapter 53-H, in the Revised Statutes Annotated (RSA) that allows two or more contiguous municipalities to form an intermunicipal governing authority through a compact. The purpose of this authority is to jointly provide various municipal services, which may include public safety, water and sewer management, solid waste, housing, planning, and transportation. The governing body of the authority will consist of representatives from each member municipality, and it will operate as a political subdivision of the state, exercising only the powers explicitly granted in the compact.

The bill outlines the powers and responsibilities of the intermunicipal governing authority, including the ability to employ staff, adopt bylaws, enter contracts, manage property, issue debt obligations, and prepare budgets. It also specifies that member municipalities must appropriate funds for their share of the authority's budget and that the authority does not have independent taxing power unless granted by the legislature. Additionally, the bill provides for the withdrawal of municipalities from the compact and the dissolution of the authority, as well as oversight provisions to ensure compliance with existing laws. The act will take effect 60 days after its passage.
