All materials within a Classified Subject Area must be reviewed

Published: 05/29/2025

DOE O 475.2B, Identifying Classified Information, requires UCOR to perform classification reviews on all documents and material within a Classified Subject Area (CSA). A CSA is simply defined as any area in which classification guidance is written. Even information that is unclassified within a CSA still requires a classification review. Classification reviews can only be conducted by a Derivative Classifier (DC) who has been trained and appointed to do so.

Documents or material to be reviewed include:

  • Newly generated documents or material in a CSA.
  • Existing unmarked documents or material that employees believe may contain classified information.
  • Existing documents or material believed to contain information that should be classified at a higher level or category.
  • Newly generated documents that contain extracts from an existing classified document.

***Adding information to a previously reviewed document IS creating a new document, and the document must be reviewed again.***

Consulting with an appropriately appointed DC prior to beginning work within a classified subject area is important. Failure to do so could result in the release of classified information that jeopardizes national security. Remember, if it’s in a CSA, it could potentially contain classified information. Employees are encouraged to read PROC-SE-1005, Classification and Information Control, and UCOR-4388, UCOR Classification and Information Control Office Policy for Review of Newly Created Media.
