An agreement among the six New England States to support the farm price of milk used for fluid consumption at a higher level than under current federally mandated minimum prices in the region. Current law allows membership in the compact to expand to New York, New Jersey, Pennsylvania, Delaware, Maryland and Virginia, if the prospective state is contiguous to a member state, and if the compact is approved by the state legislature of the prospective state and the U.S. Congress. Under law, the compact must terminate when reforms to federal milk marketing orders are implemented by USDA, which has a statutory deadline of October 1, 1999.
