Dear Mr. Pflaum:
This is in reference to a follow-up, confirmatory survey of your Wingfoot Lake Advanced Technology Center performed by Oak Ridge Associated Universities (0RAU)onJune 19, 1986. ^ As discussed with you during the survey and subsequent telephone conversations, the ORAU survey identified areas with residual radioactivity above NRC's criteria for release for unrestricted use. This criteria was given 'to you in our letters dated March 27, 1986 and June 11, 19'86. 'Since this was the second time we.have requested ORAU to perform a sufVey~ and each' time the results indicated areas with residual radioactivity exceeding NRC's criteria, we will not request ORAU to perforni further surveys until you submjt evidence that the activitiein the' areas identified in th*is s letter are below NRC's criteria. This evidence should be in the*f'orm ofa report and contain the following information: 1. The scope of the decontamination and survey. This should inc]ude a description and/or diagram of all areas decontaminated and surveyed, the decontamination procedures used, the survey grid size or blocks 'ased, the type survey perfomed (direct reading, alpha and beta-gamma, smear testing, soil samples), and the locations of samples taken. 2. The name and qualifications of the. individuals performing the decontamination and surveys. 3. The instruments and methods used to analyze the results. 4. The results of the survey keyed to the locations specified'in' Item 1 above. A., ,g V 8607100244 960707 g PDR ADOCK 0700 9

Goodyear Aerospace Corporathon. 2 UUL 07 F 7. / The following is a list of the areas that must be decontaminated, a final N a survey performed, and evidence submitted as requested above. Enclosure 1 is a diagram which will be utilized;to' describe these areas. . ~ C 1. The areas traversed by the. drain line from the sink and shower stalls through th'e spptic system. This encompasses areas where the drain was found to contain residual' radioactivity above NRC's criteria. All soil.' samples taken by ORAU down to the "T" for the drain line indicated acceptable levels for release as of June 20, 1986. However, any further decontamination and/or removal of contaminated dra.in line may have led to contamination of so{l in these areas. 2. Two areas identffied 'as-C-42 and F-48 grid blocks by ORAU survey. The C-42 grid block.is Nor'theast of the test pit area in Enclosure 1 N and Southeast of the decontamination area. The F-48 grid block is an area to the west of an area (E-48 grid block) where one-half inch of concrete 'was removed for a 30 by 50 centimeter squaret. The E-48 grid block is' located in the decontamination area in Enclosu're 1. 3. The concrete pad outside the facility known as the casing area where contaminated floors,' etc.' were deposited after removal from the Wingfoot site. r 4.- Any equipment utilized to pe'rform the decontamination (e.g.,[ vacuum cleaners, saws,.chfsels,etc.). 'Upon receipt and evaluation of your report, we will schedule ORAU to perform a final survey of the site. The survey will include the areas identified in this letter and areas where there is a potential for contamination as a resu'lt of your decontamination efforts, If ORAU's survey indicates no further areas with residual radioactivity, we will' continue with our.licensind act' ion to-release the Wingfoot site for unrestricted use. Prior to our receipt o" your report and ORAU's final surfey, it is our understanding that you will continue to renovate the sites for office use. However, you will take steps necessary to insu~re that the renoyation will not cause spread of contamination in any area identified in this letter and the soil areas where drain lines were removed can be sampled by ORAU. In addition, we understand that steps will be taken to ensure against spread of contamination in material stored in the outside casing area until the material is packaged and transferred to an authorized rec)pient. g e 9
