Title 39 › Part PART I— - GENERAL › Chapter CHAPTER 4— - GENERAL AUTHORITY › § 404
The Postal Service must run the mail and has specific powers to do so. It can collect, move, deliver, forward, hold, return, and handle undeliverable mail. It sets postage amounts and how to pay them. It decides where post offices, training centers, and equipment are needed and provides them. It makes and sells stamps and other proof of payment, offers stamp-collector services, investigates postal crimes and related civil matters, pays rewards for helpful information (giving one-half of penalties to the informer and one-half to the Postal Service Fund), and can issue a replacement check if a Postal Service check is lost, stolen, or destroyed. The Governors can set fair mail classes and rates under chapter 36; rates must be fair and enough, with honest, efficient, and economical management, to keep and improve U.S. postal services. The Postal Service must keep at least one mail class for sealed letters with a uniform rate across the United States, its territories, and possessions; one class must be the fastest, and such sealed letters may only be opened with a search warrant, to find a delivery address, or with the addressee’s permission. Before closing or combining a post office, the Postal Service must give people served at least 60 days’ notice and let them comment. It must write down and share the reasons it considered, including effects on the community and employees, savings, and consistency with the policy to provide service to rural areas; it may not consider OSHA compliance. No closing happens until 60 days after the written decision is shared. Anyone served can appeal to the Postal Regulatory Commission within 30 days; the Commission must decide within 120 days and can overturn decisions that are arbitrary, break required procedure, or lack substantial evidence. “Nonpostal service” means any service not defined as postal under section 102(5). The Postal Service is not required to offer nonpostal services except those it offered on January 1, 2006, or services allowed by chapter 37. Within 2 years after the Postal Accountability and Enhancement Act took effect, the Postal Regulatory Commission must review each nonpostal service offered on that date, decide whether it should continue based on public need and private ability to provide it, end any not approved, and classify continued services as market dominant, competitive, or experimental.
