The "Postal Operations Stay Timely And Local Act," or POSTAL Act, introduces a significant limitation on the United States Postal Service's operational changes. It specifically prohibits the USPS from closing, consolidating, or downgrading any processing and distribution center if such an action would result in a State having no remaining centers of that type. This measure is designed to guarantee that every State, including the District of Columbia, retains at least one central mail processing facility. A processing and distribution center is defined as a key mail facility responsible for distributing and dispatching both incoming and outgoing mail, providing mail preparation instructions, and operating as a sectional center, general mail facility, or dedicated mail processing facility.
