The "Protect Postal Performance Act" aims to significantly modify the United States Postal Service's (USPS) procedures for closing or consolidating post offices and processing and distribution centers. For post office closures, the bill mandates a public hearing during the 60-day notice period, allowing in-person or virtual attendance. Following the hearing, USPS must publish a summary within seven days, detailing comments received and the percentage of support or opposition, with any closure delayed for 180 days after this publication. Furthermore, the bill prohibits the closure or consolidation of a post office if it is not located within 15 miles of another post office or if it serves as the closest post office for 15,000 or more individuals. The legislation also introduces stringent requirements for processing and distribution centers (P&DCs) . It prohibits the closure or consolidation of a P&DC in a geographically non-contiguous region of a state if it would leave that region, inhabited by over 100,000 residents, without such a center. Crucially, the USPS cannot implement any changes to mail processing facilities without first obtaining an advisory opinion from the Postal Regulatory Commission (PRC) , which must be issued within 120 business days. If the PRC's opinion indicates slower delivery, USPS must publish a mitigation report, delaying implementation for 180 days, and the bill explicitly prohibits the "Mail Processing Facility Review" program. Additionally, the bill restricts P&DC closures in districts that failed to meet specific on-time delivery benchmarks in the preceding calendar year, specifically 93 percent for two-day first-class mail and 90.3 percent for three-to-five-day first-class mail. It also addresses transportation optimization efforts, prohibiting Local Transportation Optimization (LTO) and Regional Transportation Optimization (RTO) changes that would decrease the frequency of mail pickup or drop-off at any post office. The USPS must request a PRC opinion for any proposed changes to drop-off and pickup schedules under LTO or RTO, and cannot proceed with these efforts if the PRC does not recommend their implementation.
