457 of “P” approvals. This was continued until 21 November 1955 when the AEC requested the Contractor to discontinue processing Jobsite applicants for “P” approval, and on 12 December, to discontinue processing these approvals for the Honolulu and Home Office employees. A date limit of 15 February 1956, later changed to 15 March 1956, was set after which the “P” approval would not afford access to classified information. Personnel then in process for ‘“P” approval were resubmitted for processing of an “L” or “Q” clearance as appropriate for each case. Cutoff dates after which personnel at the Proving Ground would be required to be either “Q” or “L” cleared were initially established as 1 January 1956. This date was first advanced to 15 March 1956, and on 20 February 1956 was again advanced to 7 April 1956, with the provision that GSR certified personnel could be retained at Fred until 20 April 1956. At a meeting held in Albuquerque on 19 and 20 December 1955, attended by security representatives of the Contractor and AEC, a decision was reached that personnel with GSR certification could be transported to the Proving Ground provided they could be cleared by the cutoff date. (It was established that a reason- able period for processing the “L” clearance was 60 days and for the ‘“Q” clearance, 120 days.) It was also agreed at this meeting that a request for both the “L” and “Q” clearances could be made for certain individuals in order to permit the required build-up of cleared personnel. CHAPTER Ill, SECTION 7 Until the Spring of 1955 it had been the practice to cancel an applicant’s “Q” clearance if he had not been hired within 90 days after granting the clearance. The “Q’”’ clearance was also canceled on terminated employees who were not rehired within 90 days. In March 1955, an agreement was reached with the AEC Security representatives that in order to maintain a pool of cleared personnel, H&N would discontinue canceling clearances until 1 January 1956 which, at that time, was contemplated as the cutoff date. As the cutoff date had been extended until 15 March and as personnel procurement was extremely critical, on 29 December, the Contractor obtained permission to maintain all “Q” and “L” clearances on an active status until the new cutoff date. On 16 February 1956, the AEC directed the Contractor to cancel all clearances granted (prior to 1 October 1955) to those individuals who had not been hired and further, to terminate all clearances that had been granted and were not utilized within a 120-day period. Initially, all security papers required to obtain clearances were submitted to the AEC Security Branch in Los Angeles for screening and granting of clearance. On 15 June 1955, AEC screening activities for clearances were transferred to the Albuquerque Operations Office. One AEC representative remained in Los Angeles to act in a liaison capacity and to grant the GSR certification.
