FOREWORD 

This Safeguards Information (SGI) Marking Guide (MG) is issued under the authority of the 

Nuclear Regulatory Commission (NRC) and is intended to provide guidance to NRC employees. 

This Guide may also be used as guidance for any person who handles SGI. The Atomic Energy 

Act of 1954, as amended (AEA), authorizes NRC to prescribe requirements by regulation or 

order to prohibit the unauthorized disclosure of SGI. This Guide is intended to describe SGI 

marking requirements and illustrate the proper placement of required markings and warning 

notices. This Guide should be used by authorized SGI designators. The Guide does not 

address electronic safekeeping and storage of SGI, nor does it serve as a substitute for the SGI 

designator training that NRC employees must take prior to serving as an SGI designator. This 

guide proceeds on the basis that personnel involved with marking documents and materials 

have both access to and knowledge of the safekeeping and storage prerequisites needed to 

avoid inadvertent and unauthorized disclosures. This Guide illustrates where SGI designation 

would be applicable. It does not, however, override the portion marking requirement set forth in 

Title 10 of the Code of Federal Regulations (10 CFR) Section 73.22 (d) and 10 CFR 73.23 (d), 

nor does it supersede any subsequent SGI marking guidance that may be issued by NRC after 

the publication of this Guide. This Guide contains no sensitive information; documents marked 

as controlled items are for illustration purposes only. Consult your Office SGI Designator or 

NRC Information Security Branch if you have questions on SGI marking requirements. 

SGI is a special category of sensitive, unclassified information required by Section 147 of the 

AEA to be protected. Although SGI is sensitive, unclassified information, it is marked and 

protected in many aspects similar to Confidential National Security Information. All persons with 

access to SGI have a continuing obligation to protect the information from inadvertent release or 

unauthorized disclosure. Instances where an unauthorized disclosure of SGI occurs, or when 

SGI is disclosed or obtained in an unauthorized manner, must be reported to the appropriate 

authority for follow-up and corrective action. SGI possessors are reminded that: 

• Only authorized persons may designate documents etc. as SGI. Within NRC, staff 

 personnel must be trained and authorized to designate SGI. (Management Directive (MD) 

 12.7 “NRC Safeguards Information Security Program” Handbook) 

• Access to SGI is contingent upon a completed fingerprint-based Federal Bureau of 

 Investigation (FBI) identification and criminal history record check, a need-to-know and a 

 trustworthiness and reliability determination. 

• Authorized SGI designators must ensure that SGI material is appropriately marked. 

• Individuals who believe that information in their possession is not appropriately marked 

 or is inappropriately designated SGI are expected to bring their concerns to the 

 attention of an SGI designator. 

• SGI must not be disclosed over non-secure telephones. 

Proper marking of SGI material(s) serves several purposes. It alerts holders to the presence of 

SGI, identifying the exact information or portion that needs protection, identifies the name, title 

and organization of the person(s) that designated the material, specifies the date material was 

designated and warns the holder that a violation of the protection requirements could lead to 

civil and criminal penalties. Normally, a composite document (one with multiple or distinctive 

sections) would be considered a single document for protection purposes. For ease of use, it 

may be practical or appropriate to segregate sensitive information into appendices or 

attachments that can be disaggregated from the overall document.

SECURITY REMINDER 

A. Safeguards Information is sensitive unclassified information. Examples include 

 information that has intrinsic security value involving equipment, procedures, 

 communications, analyses, design basis, or response plans used by a licensee or 

 applicant to protect certain special nuclear material, byproduct material, source material, 

 or facilities. 

B. Safeguards Information is a designation, not a classification. 

C. In the context of documents that are designated “Safeguards Information,” the 

 parenthetical “U” stands for UNCONTROLLED. 

D. Any individual that is authorized to determine that a document contains SGI may remove 

the marking whenever the information no longer meets the requirements for protection as 

SGI, provided he/she coordinates with the originator, or a representative of the 

document’s originator. (NRC staff personnel should refer to NRC MD 12.7 for additional 

guidance.) 

E. Access to Safeguards Information is limited to those with a need-to-know, who have 

been deemed trustworthy and reliable (based upon a background check) and who have 

undergone a favorably-adjudicated fingerprint-based criminal history records check. 

F. Safeguards Information designators are responsible for assuring that SGI is properly 

marked. Proper markings include the identification of the basis for the designation. See 

the Designation Guide for Safeguards Information, Criteria and Guidance. 

G. Individuals who believe that information in their possession is inappropriately designated 

SGI or lacking the needed SGI designation are expected to bring their concerns to the 

attention of an SGI designator or the Information Security Branch. 

H. Safeguards Information shall not be discussed or read in public places. It should not be 

left unattended (unless on official travel and all safekeeping precautions associated with 

traveling with SGI have been taken) even for a short time in automobiles, hotel rooms, 

private residences or public lockers. Only approved security containers are authorized 

for storage. 

I. Safeguards Information shall not be discussed on non-secure telephones. 

Transmissions must take place over protected telecommunications circuits. “Talking 

around” SGI is a practice dangerous to security and must be avoided. 

J. When using a mail delivery company that provides nationwide overnight service, with 

computer tracing capability, the “waiver of signature or indemnity” block on the mail label 

may not be executed.

MEMORANDUM FOR Ms. LYNN SILVIOUS 

SUBJECT: SGI Document Markings (U) 

1. (U) This is an example of a general document that contains Safeguards Information. 

Standard markings are required for all SGI documents including: 

 a. Correspondence to and from NRC, NRC contractors, and NRC licensees; 

b. Documents pertaining to information identified in 10 CFR 73.22 (a) 73.23 (a). 

 

2. Standard markings for documents referenced above include: 

 a. (SGI) Portion marking(s) for each section of a document to reflect the designation of 

the sensitive information contained within that particular section. When subsections are 

not marked as shown below, the information is protected at the level shown by the 

overall section. 

 (1). Overall markings that are conspicuously placed at the top and bottom of the 

 Document (can be accomplished by making font larger than text of the 

 document). 

(2). Warning statement to inform the holder that a violation of the protection 

 requirements are subject to Civil and Criminal penalties. 

 (3). Subject lines and Titles should always be written as not to include sensitive 

 information. 

 

 WARNING: Violation of Section 147of the 

 Atomic Energy Act, “Safeguards 

 Information“ is subject to CIVIL 

 and CRIMINAL Penalties.

PORTION MARKINGS AND OVERALL DESIGNATION/CLASSIFICATION

1. (U) When a document contains 

several categories of sensitive 

uncontrolled information, portion marking 

is required to distinguish SGI portions 

from other portions (See Handbook 12.7, 

Part II). Mark each page with the overall 

designation (top and bottom) or with the 

highest designation of information 

contained on that page. The first page 

will always reflect the overall designation. 

2. (SGI) This is paragraph #2. If it were 

to contain “Safeguards Information,” this 

paragraph would be marked with the 

designation “SGI” in parentheses. 

SAFEGUARDS INFORMATION 

SAFEGUARDS INFORMATION

3. (OUO-SRI) Overall markings do not 

always dictate the designation of each 

paragraph. When extracts of a document 

are used to create a new document, ensure 

that the extract(s) from the source 

document is marked to reflect the actual 

designation of the extract. (When the 

source document contains sensitive 

information). 

4. (U) This is paragraph #4. If it were to 

contain “Uncontrolled Information” or “NonSensitive Information, this portion would be 

marked with the designation “U” in 

parentheses. 

 1. (SGI) This is paragraph #1. It is an SGI 

inclusive paragraph and is therefore marked 

“SGI” in parentheses as other portions on this 

page are classified. Should this paragraph be 

used to create another document, the 

information taken from this paragraph would 

remain Safeguards Information and continue to 

warrant the “SGI” portion marking. 

2. (S) If this paragraph contained “Secret” 

information, this paragraph would be marked 

with the designation “S” as indicated at the 

beginning of the paragraph. The overall 

classification on this page is “Secret” despite 

the fact that the page also contains Safeguards 

SECRET 

SECRET 

(S) Information. (See MD 12.7 Handbook 

Part ll (A)(3)) When a classified, sensitive 

but unclassified or uncontrolled paragraph 

is too long and must be carried over to 

another page, the classification or 

designation marking MUST be carried 

forward as well.

3. (OUO-PROPIN) This is paragraph #3. If 

the highest level of information in this 

paragraph was “Official Use OnlyProprietary Information, the paragraph 

would be marked with the designation 

“OUO-PROPIN” in parentheses.

MEMORANDUM FOR NSIR/DSO/DDSP April 22, 2008 

SUBJECT: “SGI Designated by” Line (U) 

1. (SGI) The identification of the designation authority and the placement of the obligatory 

warning statement are marking requirements that must not be over-looked. The 

designation authority declaration is accomplished by placing the statement “Safeguards 

Information determination made by:” on the bottom (right side) of the document. The 

warning statement is placed at the bottom, left side, of the document. The “SGI 

determination made by” line must include the name of the actual SGI designator and their 

Title. For clarity and ease of document review by others, it is recommended that the SGI 

designator also identify the basis for making the SGI determination. The Designation Guide 

for Safeguards Information (DG-SGI-1) is an excellent reference tool for making the “basis” 

determination. 

2. The SGI designation must be applied to all information that warrants protection as 

described in 10 CFR 73.21. Safeguards Information can be categorized as belonging to 

one or more distinctive Functional Series (as identified in DG-SGI-1). The applicable 

Functional Series are listed below. 

a. (U) Program Management 

b. (U) Research and Development 

c. (U) Physical Protection Program 

d. (U) Consequences, Threats, and Scenarios. 

e. (U) Incidents and Security Concern

SAFEGUARDS INFORMATION 

Rite Nuclear Facility 

Incident Report (U) 

Source Document and Portion Markings (U) 

1. (SGI) Derivatively designating a document SGI is the act of incorporating, paraphrasing, 

restating, or generating in new form, information that is already designated SGI and marking the 

newly developed material consistent with the markings of the source information. The source 

information ordinarily consists of an SGI document or documents, or the SGI designation guide 

issued by the Division of Nuclear Security, Office of Nuclear Security and Incident Response. 

This paragraph contains “Safeguards Information” that was taken from the second 

paragraph of the source document; a paragraph marked “SGI.” Therefore, this paragraph is 

marked “SGI.” 

2. When using a source document as the basis for designation, the markings on the source 

document influence the markings to be applied to the derivative document. 

(a) As with any source document containing SGI, each derivative document containing SGI 

must have portion markings and contain overall designation markings. 

(b) SGI documents will always have the obligatory warning statement and identification of 

the person who made the SGI determination. When creating an SGI document through the 

use of an SGI source document, portion markings are carried over to the new document, but 

the identification of the person making the SGI determination for the source document does 

not carry over. The newly created document, though derivative in nature, is considered a 

“new” document and as such must identify the name and title of the SGI designator.

SAFEGUARDS INFORMATION DESIGNATION FROM MULTIPLE SOURCES 

Portion Marking 

When using more than one source document to create a derivative document, portion mark the 

sensitive information that is incorporated into the derivative document with the designation 

indicated on the source documents. In the example shown below, paragraph one of the 

derivative document incorporates “Safeguards Information” from paragraphs one and two from 

Sources 1 and two respectively. Paragraph three incorporates “Uncontrolled” from paragraph 

two of Source 1.

Working Papers

Working papers are documents accumulated or created in the preparation of a finished 

document. Working papers that contain Safeguards Information must be protected from 

unauthorized disclosure and appropriately marked “Safeguards Information,” at both the top and 

bottom and contain the obligatory warning notice. Working papers that contain Safeguards 

Information do not have a time limit for the application of all associated marking. Associated 

markings (portion markings, SGI determination declaration, organization, date, basis, signature) 

are applied when the SGI working paper becomes a finished document or is transferred out of 

the office. SGI working papers will always contain the obligatory warning notice to inform the 

reader that violations of protection requirements are subject to civil and criminal penalties. 

Overall Designation Marking

The overall markings of an SGI document (assuming that SGI is the highest level of information 

contained therein) must always be conspicuously marked at the TOP and BOTTOM of the 

document. Documents containing SGI that consist of multiple pages, must have each page 

conspicuously marked “Safeguards Information” at the TOP and BOTTOM of the document. 

NOTE: Overall markings must always be conspicuous (i.e. text that is larger than the text used 

in the body of the document or a color different from the text of the document etc). 

SGI Designation from an SGI Designation Guide 

The Designation Guide for Safeguards Information is an NRC issued document that provides 

guidance and describes or identifies instances when an SGI designation is appropriate for a 

particular subject matter. Information that warrants the SGI designation retains that designation 

until the information or subject matter no longer qualifies for protection as described by 10 CFR 

Part 73. The Guide is available both in hard copy or may be viewed on NRC intranet website.

 February 14, 2009 

MEMORANDUM FOR NSIR/DSO 

SUBJECT: SGI Designation By Compilation (U) 

1. When a document consisting of individually non-sensitive items of information is 

designated SGI by compilation, the overall designation must be marked conspicuously at 

the top and bottom of each page and the outside of the front and back covers (if any). On 

very rare occasions, properly marked sensitive and/or non-sensitive unclassified 

information may, when viewed in its totality, reveal information that warrants SGI 

designation and more stringent control measures. An explanation of the basis for SGI 

designation by compilation must be placed on the face of the document or included in the 

body of the document. NOTE: If the inclusion of the basis for the SGI designation 

disrupts or interferes with the message of the document, include the basis information as 

an attachment to the document. 

2. If portions, standing alone, are non-sensitive information, but the document is SGI by 

compilation, mark the document and pages “Safeguards Information” at the top and 

bottom. If individual portions are designated sensitive unclassified information (i.e. SSI, 

OUO-SRI etc.), but the compilation warrants SGI designation, mark each portion with its 

original designation, and mark the document and pages “Safeguards Information” as 

dictated by the compilation of information rule. Always include the basis for the SGI 

designation when that SGI designation is predicated on the compilation of information 

rule.

the person making the SGI determination. When maps, blueprints etc. (things that will be rolled up 

for storage) are used, aside from the markings on the face of the item, the backside of the rolled 

item must also be marked. Wrapping an SGI Coversheet around the rolled item is an acceptable 

means of alerting others to the presence of Safeguards Information. 
 19 

Electronic Media 

With the exception of the warning notice and identification of the person making the Safeguards 

Information determination, basic document marking rules apply to computer media. As shown 

below, a computer disk must be labeled to reflect its SGI content. When labeling computer 

disks, use NRC Form 461A or labels that are called for in local governing directives. 

No prescribed NRC Form exists that can be applied directly to a Compact Disc (CD) or a Digital 

Video Disc (DVD) that contains Safeguards Information. The NRC Form 461A, or label that is 

called for by local governing directives, may be used to mark the CD or DVD case. Many CD 

and DVD labeling products exist and CD or DVD users are encouraged to use CD or DVD 

labeling products when they are available. When using a CD or DVD labeling product, keep in 

mind that the text used to make the caption “Safeguards Information” must be conspicuous and 

unobstructed by any other markings or text on the CD or DVD label. If text, other than the 

“Safeguards Information” caption is used on the CD or DVD label, NO SAFEGUARDS 

INFORMATION SHOULD BE PLACED ON THE CD OR DVD LABEL. NRC approved thumb 

drives, containing SGI, must be color coded as prescribed by NUREG/BR-0168, Revision 4 and 

be conspicuously marked with the words “Safeguards Information.” 

In the event that CD or DVD labels aren’t readily available or local directives forbid their usage, 

use of a permanent marker is permissible. The text used to create the “Safeguards Information” 

caption, when written with a permanent marker, must be conspicuous and unobstructed by 

other markings or text that may be placed on the CD or DVD. 

This medium is sensitive unclassified

 SLIDE AND TRANSPARENCY

Slides and Transparencies containing Safeguards Information must have markings on the slide 

cover and the actual image. The identification of the person making the SGI determination, 

along with position title, date and warning notice must be placed on the border or frame for the 

slide or transparency. If multiple slides or transparencies are created and considered one (1) 

presentation product, mark only the top or first transparency with the SGI associated marking 

information (i.e. SGI determination official’s, title, date, basis and the SGI warning notice). 

File folders and binders used to hold slides or transparencies, or any other SGI, must be 

conspicuously marked “Safeguards Information” on the Top and Bottom, Front and Back when 

the folder or binder is outside of the security container. Safeguards Information Cover sheets 

may be used to satisfy this requirement. If binders are stored in a manner that conceals the 

Safeguards Information marking, the spine of the binder must also be marked to indicate the 

designation of its content.
