Subject to the provisions of section 404a, but otherwise without limitation of the generality of its powers, the Postal Service shall have the following specific powers, among others:

(1) to provide for the collection, handling, transportation, delivery, forwarding, returning, and holding of mail, and for the disposition of undeliverable mail;

(2) to prescribe, in accordance with this title, the amount of postage and the manner in which it is to be paid;

(3) to determine the need for post offices, postal and training facilities and equipment, and to provide such offices, facilities, and equipment as it determines are needed;

(4) to provide and sell postage stamps and other stamped paper, cards, and envelopes and to provide such other evidences of payment of postage and fees as may be necessary or desirable;

(5) to provide philatelic services;

(8) to authorize the issuance of a substitute check for a lost, stolen, or destroyed check of the Postal Service.

Except as otherwise provided, the Governors are authorized to establish reasonable and equitable classes of mail and reasonable and equitable rates of postage and fees for postal services in accordance with the provisions of chapter 36.

The Postal Service shall maintain one or more classes of mail for the transmission of letters sealed against inspection. The rate for each such class shall be uniform throughout the United States, its territories, and possessions. One such class shall provide for the most expeditious handling and transportation afforded mail matter by the Postal Service. No letter of such a class of domestic origin shall be opened except under authority of a search warrant authorized by law, or by an officer or employee of the Postal Service for the sole purpose of determining an address at which the letter can be delivered, or pursuant to the authorization of the addressee.

The Postal Service, in making a determination whether or not to close or consolidate a post office—

(1) The Postal Service, prior to making a determination under subsection (a)(3) of this section as to the necessity for the closing or consolidation of any post office, shall provide adequate notice of its intention to close or consolidate such post office at least 60 days prior to the proposed date of such closing or consolidation to persons served by such post office to ensure that such persons will have an opportunity to present their views.

The Postal Service, in making a determination whether or not to close or consolidate a post office—

(A) shall consider— (i) the effect of such closing or consolidation on the community served by such post office; (ii) the effect of such closing or consolidation on employees of the Postal Service employed at such office; (iii) whether such closing or consolidation is consistent with the policy of the Government, as stated in section 101(b) of this title, that the Postal Service shall provide a maximum degree of effective and regular postal services to rural areas, communities, and small towns where post offices are not self-sustaining; (iv) the economic savings to the Postal Service resulting from such closing or consolidation; and (v) such other factors as the Postal Service determines are necessary; and

(B) may not consider compliance with any provision of the Occupational Safety and Health Act of 1970 (29 U.S.C. 651 et seq.).

(3) Any determination of the Postal Service to close or consolidate a post office shall be in writing and shall include the findings of the Postal Service with respect to the considerations required to be made under paragraph (2) of this subsection. Such determination and findings shall be made available to persons served by such post office.

(4) The Postal Service shall take no action to close or consolidate a post office until 60 days after its written determination is made available to persons served by such post office.

A determination of the Postal Service to close or consolidate any post office may be appealed by any person served by such office to the Postal Regulatory Commission within 30 days after such determination is made available to such person under paragraph (3). The Commission shall review such determination on the basis of the record before the Postal Service in the making of such determination. The Commission shall make a determination based upon such review no later than 120 days after receiving any appeal under this paragraph. The Commission shall set aside any determination, findings, and conclusions found to be—

(A) arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with the law;

(B) without observance of procedure required by law; or

(C) unsupported by substantial evidence on the record.

For purposes of paragraph (5), any appeal received by the Commission shall—

(A) if sent to the Commission through the mails, be considered to have been received on the date of the Postal Service postmark on the envelope or other cover in which such appeal is mailed; or

(B) if otherwise lawfully delivered to the Commission, be considered to have been received on the date determined based on any appropriate documentation or other indicia (as determined under regulations of the Commission).

Not later than 2 years after the date of enactment of the Postal Accountability and Enhancement Act, the Postal Regulatory Commission shall review each nonpostal service offered by the Postal Service on the date of enactment of that Act and determine whether that nonpostal service shall continue, taking into account—

(1) In this subsection, the term “nonpostal service” means any service that is not a postal service defined under section 102(5).

(2) Nothing in this section shall be considered to permit or require that the Postal Service provide any nonpostal service, except that the Postal Service may provide nonpostal services which were offered as of January 1, 2006, as provided under this subsection.

Not later than 2 years after the date of enactment of the Postal Accountability and Enhancement Act, the Postal Regulatory Commission shall review each nonpostal service offered by the Postal Service on the date of enactment of that Act and determine whether that nonpostal service shall continue, taking into account—

(A) the public need for the service; and

(B) the ability of the private sector to meet the public need for the service.

(4) Any nonpostal service not determined to be continued by the Postal Regulatory Commission under paragraph (3) shall terminate.

(5) If the Postal Regulatory Commission authorizes the Postal Service to continue a nonpostal service under this subsection, the Postal Regulatory Commission shall designate whether the service shall be regulated under this title as a market dominant product, a competitive product, or an experimental product.
