On 12 November 1942, the Secretary of War and Standard Oil Co. (San Francisco) entered into an agreement (unnumbered lease to run with lease W-868-ENG-4504), whereby Standard Oil agreed to install, operate, and maintain lubricating oil storage and distribution facilities at the site. In addition, on 20 December 1943, the CAA was granted a permit (to run with Lease No. W-868-ENG-4505) to use and occupy two parcels of land totaling 11.2 acres at the Modification Center for a radio range and communication building site, together with a right of way between the two parcels for establishing and maintaining subsurface cable lines. The original permit period ended 30 June 1944, however, the lease contained a provision for annual renewal, at the option of the government, through 30 June 1967. Upon the expiration of the permit, all CAA property was to have been removed to a condition satisfactory to the Commanding Office or other competent military authority.
