CHAPTER Ill, SECTIONS 6 and 7 - Top Secret, Secret, and Confidential. Undisturbed in this order was the classification of Defense Information (known as Restricted Data) as defined in the Atomic Energy Act of 1946. The only immediate effect this order had on H&N security procedures was the requirement that all Confidential, Defense Information be registered when transmitted by U.S. Mail. INFORMATION SECURITY The scope of the activities of Holmes & Narver during the Operation, the numbers of personnel who required access to classified in- formation, and the necessity for transferring voluminous classified documents between the Los Angeles Home Office and the Pacific Proving Ground dictated that uniform procedures and practices must be followed to insure that all classified information remained in the possession of authorized recipients. All classified mail received in the Home Office was directed to Central Files. Papers were logged in and then delivered by messengers appropriately cleared and approved. Classified documents were delivered to the Pacific Proving Ground by “Q” cleared employees acting as couriers. For transmittals between the Home Office and AEC’s Los Angeles Security Branch, theservices of a “Q” cleared armed guard were used. At both the Pacific Proving Ground and the Home Office, documents no longer required were destroyed in accordance with AEC security procedures. The Field Manager, Eniwetok Field Office, delegated authority to the General Manager of Holmes & Narver to classify documents originated by H&N, and empowered him to redelegate to key personnel within the organization. In addition to the foregoing, the informa- tional control program included the establish- ment of practices and procedures to insure that all cleared personnel were aware of their continuing responsibility to the United States Government not to divulge classified information to unauthorized personnel. Each employee at the Home Office was given a security interview upon receiving his clearance, at which time the broad scope of the security program, was outlined, and examples were cited to point up the necessity for constant vigilance. Employees assigned to the Pacific Proving Ground were cautioned prior to departure, not to discuss anything concerning their job with their family, friends, or other individuals. A comprehensive security lecture was deferred until the employee arrived at the Jobsite. After having the lecture at the PPG, each employee took a written test. If the employee failed in the test, he was required to take it a second time. Top H&N management personnel were given a special lec-ture in addition to the over-all lecture delivered to general employees, and were required to sign a document acknowledging their security responsibility as management personnel. In the Home Office, all terminating employees were given a security lecture and were required to execute and have witnessed by the Security Department a security termination statement, Form AEC-136, which included Section 10(b) of the Atomic Energy Act of 1946, The Internal Security Act of 1950, and Title 18, U.S. Code, Section 794. Jobsite employees were given a security lecture prior to their departure for their place of hire and were requested to sign the AEC Form 136. Upon arrival, whether it was at Honolulu, San Fran- cisco, or Los Angeles, each terminating employee was again given a comprehensive security lecture, was again requested to sign the AEC Form-136, and was reminded of his responsibility to notify the Commission of any anticipated foreign travel. For those employees anticipating foreign travel, Holmes & Narver prepared Form AEC-290 and submitted it to the AEC, Los Angeles Security Branch. SECTION 7 OFFICE SERVICES To provide more efficient workability, the Office Services Department in the Home Office underwent a reorganization early in June 1953, and an Office Manager wasplaced in charge. The central file room, mail room, teletype room, telephonefacilities, reproductions (except Ozalid prints), warehousing and records, stores issue, AECcar pool, furniture and equipmentalloca- tions, all maintenance work, and inter-office Messenger service were assigned to this depart- ment. The mail room handled approximately 2,500 lbs. of incoming mail per month, and an equivalent amount of outgoing mail. All mail was logged in and out by cleared personnel; mail was delivered within the Home Office by messengers runs daily. The reproduction work required for Operation CASTLE, such as Multilith, Ditto, Mimeograph and Autostat, was produced by the Office Services facilities, and averaged 50,000 sheets Page 3-35
