Disposal and Destruction

Classified documents and material identified for destruction shall be destroyed completely, to prevent anyone from reconstructing the classified information. This may be determined by the agency as long as approved methods are followed.

Approved methods and equipment routinely used include:
  • Burning
  • Crosscut shredding*
  • wet pulping
  • mutilation
  • chemical decomposition or pulverizing
*Only crosscut shredders listed on the NSA/CSS Evaluated Products List (EPL) for High Security Crosscut Paper Shredders may be used to destroy classified material. Those agencies having crosscut shredders capable of maintaining a shred size of 1/2 inch by 1/32 inch (variance of 1/64 inch) may continue to be used, EXCEPT for destruction of COMSEC materials. However, those crosscut shredders requiring replacement of the unit and/or rebuild of the shredder blades assembly MUST BE REPLACED by a crosscut shredder on the latest NSA/CSS EPL.
