§310.4. Responsibility of carriers. — Inbound Citations

(b) Carriers operating under the suspension granted pursuant to § 320.2 are responsible for making sure that their carriage of matter under the suspension meets all conditions contained in § 320.2. (See § 310.4.) The containers or covers of any matter carried under the suspension must be made available for examination upon request by a properly identified representative of Mailing Standards. Carrier records—either in the form of notations on the containers or covers of any matter carried under the suspension granted pursuant to § 320.2 or in the form of records kept by employees of the actual times they make delivery or pickup stops—must be sufficient to show that the delivery of such matter was completed within the applicable time limitation prescribed in § 320.2. The provisions of this paragraph shall not restrict the Postal Service in the exercise of search powers conferred upon it by law.

The operation of 39 U.S.C. 601(a) (1) through (6) and § 310.2(b) (1) through (6) of this chapter is suspended on all post routes to permit colleges and universities to carry in their internal mail systems the letters of their bona fide student or faculty organizations to campus destinations. This suspension does not cover the letters of faculty members, students, or organizations other than bona fide student or faculty organizations of the carrying college or university. Colleges and universities choosing to provide their student or faculty organizations access to their internal mail systems are responsible for assuring that only letters of bona fide student or faculty organizations addressed to campus destinations are carried. (See § 310.4.) For purposes of this suspension, “internal mail systems” are those which carry letters on, between, and among the various campuses of a single college or university and which operate in accordance with the Letters of the carrier exception in 39 CFR 310.3(b).
