was based on a then expected required Holmes & Narver personnel total of 1467 during January 1951, and 1430 during February 1951. By the middle of November, everyone at Jobsite wes in process for "Q" clear- ance except those definitely known to be leaving through contract com- pletion prior to January 15, 1951. In November, additional men were being hired as rapidly as possible to meet urgent construction deadlines, For example, on about November 15, 1950, it was determined that 70 laborers would be needed immediately for an extremely urgent grouting job that had to be completed prior to January 31, 1951, to avoid the jeopardizing of certain test experiments, At that time there were few cleared laborers avail- able with even a "P" approval. To meet this situation, arrangements were made with the Director of Security at Los Alamos to grant local check "P* approvals to newly recruited laborers so that they could be sent to the Jobsite with a minimum of delay. A special recruiting party was sent to Dallas, Texas, for the purpose of utilizing the favorable labor market there, An AEC security representative and a Holmes & Narver security officer accompanied the party to process local check "P* approvals, As a result, "P" approvals were received quickly, and the personnel requisition for laborers was filled in a minimum of time. However, there was little possibility that these men could be given a "Q" clearance until a considerable time after the limiting date of January 15, 1951, On December 14, 1950, it was requested of the Manager, AEC, Santa Fe Operations Office, that the limiting date be extended to March 1. 1951, because it waa apparent that there would pot be sufficient "Q" cleared personnel atthe Jobsite by January 15.~ Extension was granted to February 15, 1951“; and for employees on Parry and Eniwetok Islands only, extension was later granted to March 1, 19513, - During the period between November 1, 1950, and January 15, 1951, approximately 580 new employees were sent to Jobsite, and on January 31, 1951, a peak number of 1841 Holmes & Narver employees was reached, After January 31, 1951, and until the end of the operational period job personnel requirements continued to be considerably im excess of previous estimates and shortages developed in several job categories, including the messing, marine and power, and water distillation operations. This was due largely to the excessive over-all population, Instead of the 2000 expected, there were actually 2800, In addition, the time required to process "Q" clearances had increased to approxi- mately 9O days. letter, CHN-1133, dated December 14, 1950.
