PART 1016_SAFEGUARDING OF RESTRICTED DATA--Table of Contents
 
Sec.  1016.32  Classification and preparation of documents.

    (a) Classification. Restricted Data generated or possessed by an 
Access Permit holder must be appropriately marked. CG-UF-3, ``Guide to 
the Unclassified Fields of Research,'' will be furnished each permittee. 
In the event a permittee originates classified information which falls 
within the definition of Restricted Data or information which he is not 
positive is not within that definition and CG-UF-3 does not provide 
positive classification guidance for such information, he shall 
designate the information as Confidential, Restricted Data and request 
classification guidance from the DOE through the Classification Officer 
at the Operations Office administering the Permit, who will refer the 
request to the Director, Office of Classification, U.S. DOE, Washington, 
D.C. 20545 if he does not have authority to provide the guidance.
    (b) Classification consistent with content. Each document containing 
Restricted Data shall be classified Secret or Confidential according to 
its own content.

[[Page 787]]

    (c) Document which custodian believes improperly classified or 
lacking appropriate classification markings. If a person receives a 
document which, in his opinion, is not properly classified, or omits the 
appropriate classification markings, he shall communicate with the 
sender and suggest the classification which he believes appropriate. 
Pending final determination of proper classification, such documents 
shall be safeguarded with the highest classification in question.
    (d) Classification markings. Unless otherwise authorized below, the 
assigned classification of a document shall be conspicuously marked or 
stamped at the top and bottom of each page and on the front cover, if 
any, and the document shall bear the following additional markings on 
the first page and on the front cover:

                             Restricted Data

    This document contains Restricted Data as defined in the Atomic 
Energy Act of 1954. Its transmittal or the disclosure of its contents in 
any manner to an unauthorized person is prohibited.

    (e) Documentation. (1) All Secret documents shall bear on the first 
page a properly completed documentation stamp such as the following: 
This document consists of -- pages. Copy No. -- of -- Series --.
    (2) The series designation shall be a capital letter beginning with 
the letter ``A'' designating the original set of copies prepared. Each 
subsequent set of copies of the same documents shall be identified by 
the succeeding letter of the alphabet.
    (f) Letter of transmittal. A letter of transmitting Restricted Data 
shall be marked with a classification at least as high as its highest 
classified enclosure. When the contents of the letter of transmittal 
warrant lower classification or requires no classification, a stamp or 
marking such as the following shall be used in the letter:

When separated from enclosures handle this document as ----.
    (g) Permanently fastened documents. Classified books or pamphlets, 
the pages of which are permanently and securely fastened together, shall 
be conspicuously marked or stamped with the assigned classification in 
letters at least one-fourth (\1/4\) inch in height at the top and bottom 
on the outside front cover, on the title page, on the front page, and on 
the inside and outside of the back cover. The additional markings 
referred to in paragraph (d) of this section shall be placed on the 
first page and on the front cover.
    (h) Physically connected documents. The classification of a file or 
group of physically connected documents shall be at least as high as 
that of the most highly classified document therein. It shall bear only 
one overall classification, although pages, paragraphs, sections, or 
components thereof may bear different classifications. Each document 
separated from the file or group shall be handled in accordance with its 
individual classification.
    (i) Attachment of security markings. Documents which do not lend 
themselves to marking or stamping shall have securely affixed or 
attached a tag, sticker, or similar device bearing the appropriate 
security markings.
