PART C - CLASSIFICATION/SECURITY MARKINGS
1. GENERAL.
a. All document originators are responsible for ensuring that the
necessary classification/security markings are placed on a
classified document. These include:
(1) Classification level;
(2) Classification category;
(3) Date of classification;
(4) Name, position title, and organization of the Authorized
Classifier;
(5) Designation of the guide or source document, if derivatively
classified (NSI only);
(6) Duration of classification (NSI only);
(7) Office of origin; and
(8) Special markings (if required).
Refer to DOE 5635.1A, CONTROL OF CLASSIFIED DOCUMENTS AND
INFORMATION, for rules concerning the use, format, and placement of
classification security markings. This Order describes only
certain markings directly related to the classification of a
document.
2. CLASSIFICATION AUTHORITY. All NSI classified documents must indicate
the source of classification authority (i.e., a classification guide or
a source document) which is the basis for the document's classification.
For NSI, RD, and FRD documents, the name, position title, and
organization of the Authorized Classifier of the document must be
indicated. Documents originated by individuals without appropriate
classification authority must be reviewed by an Authorized Classifier
having the appropriate authority when it is reasonable to expect that
the documents contain classified information or when regulations or
other requirements apply. Note that the identification of the
classifier of a document, as required in the following paragraphs, is
the Authorized Classifier who makes the classification determination.
This may or may not be the individual who might prepare or sign the
document.
a. Restricted Data or Formerly Restricted Data. The following rules
apply to all classified documents that contain RD or FRD,
regardless of whether they also contain NSI.
(1) The basic classification authority for documents that contain
RD or FRD is the Atomic Energy Act. These documents are
always derivatively classified and may, therefore, be
classified by an Original or Derivative Classifier. The
"Derivative Classifier" line on the document must be completed
with the name, position title, and organization of the
classifier of the document. In those cases where the signer
of the document itself is the Derivative Classifier, the word
"signer" may be substituted for the name and position title of
the classifier.
b. National Security Information Only. The following rules apply to
classified documents that contain only NSI (i.e., they do not
contain any RD or FRD).
(1) Originally Classified. If the classification of a document is
not based on classification guides or source documents, the
document must be classified by an Original Classifier. The
"Originally Classified by" line on the document must be
completed with the name, position title, and organization of
the Original Classifier. In those cases where the signer of
the document itself is the Original Classifier, the word
"signer" may be substituted for the name and position title of
the Original Classifier. (Note: Such documents must be
portion marked. See page V-16, Chapter V, Part C, paragraph
5, for more detailed information.)
(2) Derivatively Classified. If the classification of a document
is based on the use of a classification guide, a source
document, or an Original Classifier's determination, the
document must be classified by an Original or Derivative
Classifier. The "Derivatively Classified by" line on the
document must include the identity of the classification
source (e.g., a classification guide or the date and
originator of the source document that served as the basis for
the classification determination). The "Derivative
Classifier" line on the document must be completed with the
name, position title, and organization of the classifier of
the document. In those cases where the signer of the
document itself is the Derivative Classifier, the word
"signer" may be substituted for the name and position title of
the classifier.
(3) More Than One Classification Source. If the classification of
a document is based on more than one classification guide,
source document, or Original Classifier determination, the
"Derivatively Classified by" line must include the term
"Multiple Sources." The classifier shall include the
identification of each classification source, as specified in
the previous two paragraphs, with the file or record copy of
the document. Otherwise, the rules for classification
marking are as specified in the two preceding paragraphs.
3. DURATION OF CLASSIFICATION.
a. Restricted Data or Formerly Restricted Data. Documents that
contain RD or FRD (regardless of whether they also contain NSI)
remain classified indefinitely. Therefore, they are never to be
marked for declassification or review. Such documents do not
require a "Declassify on" line.
b. National Security Information Only. Documents that contain NSI
(i.e., they do not contain any RD or FRD) shall be marked for
declassification in accordance with the following:
(1) Originally Classified. If the classification of a document is
not based on the use of classification guides or source
documents, the Original Classifier of the document shall set a
specific date or event for declassification at the time the
information is originally classified, if possible. The
"Declassify on" line on the document must be completed with
this date or event. When a specific date or event for
declassification cannot be determined at the time of original
classification, the "Declassify on" line on the document must
be completed with the following: "Originating Agency's
Determination Required" or "OADR."
(2) Derivatively Classified.
(a) If the classification of a document is based on the use
of classified information from a source document, the
declassification instructions of the source document
should be carried forward to the "Declassify on" line of
the new document.
1 Documents deriving their classification from a source
document classified pursuant to Executive Order 12356
shall carry forward the declassification instructions
from the source document.
2 Documents deriving their classification from a source
document classified pursuant to predecessors of
Executive Order 12356 should be marked for
declassification according to the conversion table in
Chapter X, Part F. See also page VI-5, Chapter VI,
Part B, paragraph 2.
(b) If the classification of a document is based on
instructions in a classification guide, those
instructions should be followed.
1 Documents deriving their classification from a
classification guide issued pursuant to Executive
Order 12356 shall be marked with the latest date or
event for declassification specified for the
information concerned or with the indication that the
"Originating Agency's Determination (is) Required"
(OADR) if this instruction is specified for any
information in the document under review.
2 Documents deriving their classification from a
classification guide issued pursuant to predecessors
of Executive Order 12356 should be marked for
declassification according to the conversion table in
Chapter X, Part F. See also page VI-5, Chapter VI,
Part B, paragraph 2.
(c) If the classification of a document is derived from a
classification guide or source document that does not
specify declassification instructions, the "Declassify
on" line should be completed with "OADR."
(d) Documents deriving their classification from more than
one classification guide or source document shall be
marked with the latest occurring date or event for
declassification indicated in the classification guides
or source documents or with "OADR," as appropriate.
4. OBSOLETE MARKINGS. Certain classification or security markings that are
no longer used or have a different meaning are defined below. Prior to
any use or distribution, old documents marked with these terms shall be
reviewed by a classifier or declassifier to determine their current
classification status. The markings of such documents shall be changed
to show their proper classification. Pending this review, such
documents issued in the time periods indicated below shall be
safeguarded as Confidential-NSI documents.
a. Restricted. The term "Restricted" is an obsolete classification
marking that identifies a security level less sensitive than
"Confidential." Note that "Restricted" is an active classification
marking still used by some foreign governments and international
organizations.
b. Official Use Only. From 7-18-49 to 10-22-51, the Atomic Energy
Commission used the term "Official Use Only" ("OUO") as a security
marking equivalent to the term "Restricted" defined in the previous
paragraph. (Note: This marking is currently used as a designation
for certain sensitive but unclassified information which requires
some degree of protection.)
5. PORTION MARKING.
a. In accordance with the provisions of section 1.5(b) of Executive
Order 12356, a waiver has been granted to the requirement of that
section to portion mark the following types of documents:
(1) Documents which contain both RD or FRD and NSI.
(2) Documents which contain only NSI and which are derivatively
classified.
b. Thus, portion marking is required for documents containing only NSI
which have been originally classified.
c. Any document containing only RD or FRD is not under the
jurisdiction of Executive Order 12356. Such a document is not
portion marked. (See DOE 5635.1A for the exception regarding
classification markings on titles of classified documents.)
d. This waiver was sought because it is the position of DOE that the
use of classification guides clearly is a superior method for
providing guidance to Derivative Classifiers.
e. If portion marking an originally classified NSI-only document is
not practicable, the document shall contain a statement sufficient
to identify the information that is classified, the level of such
classification, and the information that is not classified. If all
portions of a document are classified at the same level, this fact
should be indicated by a statement to that effect on the face of
the document.
6. SANITIZED DOCUMENTS AND EXTRACTS. Documents should not be sanitized
unless sanitization is specifically required or requested. In the case
of documents being sanitized in response to FOIA requests, notification
of sanitization shall be given only to the requester. Each extract or
sanitized version of a numbered classified document (i.e., those with
report numbers, document numbers, etc.) will be assigned a new, unique
number. If necessary, the new version may also be identified as being
an extract or sanitized version of the original document by including
the term "extract" in the title of the new document. When an extract is
declassified, the declassification notice will specifically state that
the new document is an extract.
7. MOSAIC COMPILATION. When a compilation of unclassified or classified
information must be protected by classifying it at a level higher than
any of the included information, the overall classification shall be
placed on the document and the basis for that classification included in
the document (e.g., on the first or cover page). In addition, the first
or cover page of the document shall contain the following statement:
"This document has been classified under the `mosaic compilation'
concept and shall not be used as the source for a derivative
classification decision."
