" arch 21, 1979, UPPSS responded to the enclosed round onc questiens by stating "The Supply Systen is presently in the process of reviewinc infomation relative to these questions. I!c will provide a schedule for the subaission of the responscs p'rior to April 30, 1970." As of this dato, UPPSS has nado no attecpt to contact the project nanager to provide a schedule to subnit adequate responses to round one geology questions. On 'ay 9,1970 round tuo acolo,y questions were to be submitted to the licensing project manager. The staff is unable to continue the site revicu and preparc round tuo questions until adequate responses to round one geoloqy questions arc received. The revicu schedule for UPPSS-2 uill have to be revised accordinoly.

s Q 360.4 In the Weston Geophysical Research, Inc., report, " Qualitative Aeromagnetic Evaluation of Structures in the Columbia Plateau and adjacent Cascade maountain Area," March 28, 1978, Figure 13 shows several north to northwest trending aeromagnetic linears in the vicinity of Badger Mountain and Jump Off Joe Anticline.
- However, the Weston report does no discuss the origin or interpretations of these particular linears.
The north trending linear crossing the Columbia River at the junction with the Snake River has an apparent offset of the magnetic low defining the Rattlesnake Hills anomaly.
Since-these aeromagnetic linears trend toward the WNP-2 site, provide:
(1) an interpretation of these features, including but not limited to the potential for their continuation to the north to near site area: and (2) a discussion of the fault parameters, if such an interpretation is proposed.
- Response:
The Supply System is presently in the process of reviewing information relative to these questions. We will provide a schedule for the submission of a response prior to April 30, 1979.

i Q
3G0.5 So.T.e of tha data and discussions in the F,SAR of thnse Columbia Plateau structures relevant to the WNP-2 site are slightly different from the information provided in Amendment 23 to the WNP 1 & 4 PSAR (Cocket flos. 50-460 and 50-513).
For example, i
with regard to the Wallula Gap Fault, your FSAR states that the "... probable fault 'aovement cccurred after.the deposition of the Touchet beds, and thus less than 12,000 years ago."
However, in Appendix 2RH.4 of the WNP l& 4 PSAR (Amendment 23), you indicate th'at the fault is older than the Quaternary i
Kenneweck fanglomerate based on trenching.
Additionally, in this same amandment to the UNP 1 & 4 PSAR, you indicate that the fa'ulting along the llorse Heaven Hill Anticlina occurred about 3.5 million years before the present (mybp).
The WNP-2 FSAR does not discuss this particular point but, rather, qu2stions the existence of faulting along the Horse lieaven Hill Anticline and indicates that it could be the sole result of folding.
Clarify these apparent discrepancies and provide cross-references in the WNP-2 FSAR to the appropriate sections of the WNP 1 & 4 PSAR.
Resp'onse:
The Supply System is presently in the process of reviewing information relative to these questions, t.'e will provide a schedule for the submission of a response prior to April 30, 1979.
