A bill to amend title 39 of the United States Code to provide for congressional review of proposed changes in postal services.

Directs the Postal Service to submit to Congress (rather than to the Postal Rate Commission) any proposed change in the nature of postal service which would have nationwide impact. Requires any statement of proposed change so submitted to include an estimate of the impact of such change upon the public, business mail users, service levels and postal finances. Provides that no proposed change shall become effective if either House of Congress adopts a resolution disapproving it within 60 days after it is submitted to Congress.
