Genera.; Electric Test Reactor Vallecitos Nuclear Center Vallecitos, California Docket Number 50-70 Supplement to Status Review The letter from R. W. Darmitzel, General Electric Company, to C. Nelson, NRC, dated July 12, 1979, raises t he point that USGS Professional Paper 943 does not show either the Verona nor the Las Positas faults and that this point should be considered along with the applicant's data regarding the geology of the Livermore area.
Professional Paper No. 943 " Flatland Deposits -- Their Geology and Engineering Properties and the Im7 ortance to Comprehensive Planning" was published in 1979, and therefore post-dates the publication of Open File Map 77-689 (1977) in which the Verena and Las Positas f aults are shown. Although PP 943 was published in 1979, the authors manuscript was submitted in 1976 and received approval March 2,1977. Data in the raport thus pre-date Open File Map 77-689 and omission of the Verona and Las Posit.> faults as described by Herd becomes understandable.
Furthermore PP 943 is principally a study of Pleistocene and younger stretigraphic units and the accompanying maps plates 1, 2 and 3 were not inteeded to show all faults in the areas depict 2d.
For instance the Hillside fault, Miller Creek fault, Cull Creek fault and Bolinger fault are extmples of the many others not shown.
Tha apparent omission of the Verona and Las Positas faults from maps in PP 943 therefore provides no basis for emphasis, pro or con, in the review of geologic data pertinent to the Vallecitos GETR site.
