The Postal Processing Protection Act aims to strengthen public oversight regarding the closure of United States Postal Service (USPS) facilities. Currently, specific requirements, including public notification and opportunities for community input, govern the closure of post offices. This legislation amends title 39, United States Code, to extend these existing requirements to a wider array of USPS infrastructure. It mandates that any acceptance, processing, shipping, delivery, distribution, or other facility owned or operated by the Postal Service that supports one or more post offices must now adhere to the same closure procedures. This expansion ensures that communities have a voice in decisions impacting critical postal operations beyond just their local post office branches.
