Since its founding, CSG’s Compact Center has worked to promote the use of interstate compacts as an ideal tool to meet the demand for cooperative state action.  During that time there have been approximately 180 adoptions of CSG supported compacts, including 10 separate adoptions of different projects during the 2014 legislative session. Two of those compacts have expanded to all 50 states, while the Educational Opportunity for Military Compact has now grown to 48 states.  Below is a summary of various CSG compact projects.

The creation of the Port Authority of New York and New Jersey in 1922 through an interstate compact signaled a significant shift in the use and application of interstate compacts. For the first time states began using compacts to establish regulatory agencies with the authority to act on the state’s behalf. Known as administrative compacts, these agreements frequently allow for a sophisticated governing structure that possess the authority to pass rules, draft bylaws, form committees, and hire staff to carry out the daily operations of the compact.  

Interstate compacts are contracts between two or more states creating an agreement on a variety of issues, such as specific policy challenges, regulatory matters and boundary settlements. This brief provides background on the history of compacts, their primary purposes, and information about compacts affiliated with the National Center for Interstate Compacts.
