Subject:
WNP-2 Request for Additional Information As a result of our review of your application for operating loco'ense we find that we need additional information regarding the WNP-2 FSAR.
The specific information required is as a result of the Geosciences meeting on Nov'ember 17-18, 1981,;
,and is listed in the enclosure.
A draft copy of these questions was sent on November 20.
To maintain our licensing review schedule for the WNP-2 FSAR, please provide responses to the enclosed request as soon as possible.
If you desire any clarification, please con'tact Ina Alterman at (301) 492-7850 or Jeff Kimball at (301) 492-8990 or"Raj Auluck at (301) 492-9778.
Sincerely,

ENCLOSURE Provide your best deterministic judgement of the length, character, and capability of CLEW within the site region.
If you determine it to be segmented as reported in the meeting of Nov. 17-18, 1981, provide a
map with topographic base delineating the segments and discuss in detail the character and capability of the individual segments, with suppor ting basisfor all judgements.
(Contact Ina Alterman, GSB, 301-492-7856).
Concerning the.Wallula Gap fault near Yellepit:
a.
Provide an explanation of the difference in age of the Kennewick fanglomerate as reported in FSAR amendment 18, Section 2.5.1.2.4.5 on p. 2.5-96 and in Appendix 2.5N.8. 1..6.
b.
Was the block of ash that was observed in the down-dropped block at the fault in the Yellepit trench'ated'?
If so, what age has been determined 'for it? If not, are there samples of that ash presently available for dating?
(Contact Ina Alterman,G SB, 301-492-7856).
In a report prepared for the U. S.
Corps of Engineers (Slemmons and O'alley, 1979-1980):
a.
Figures 20a and 20b are from Vansycle Canyon:
Have the youthful-appearing faceted spurs having linear character been investigated for possible young age and, therefore, capability?
What is the explanation for this feature?
I b.
Figures 21aand 2lb taken south of Umapine:
Has the pronounced escarpment on the lower third of the hi 11 in the center/upper right of 2la and in the center right of 2lb been investigated for possible recent movement?
What is the explanation for this feature?
(Contact Ina Alterman, GSB, 301-492-7856 or 0.

I Reevaluate the structural and/or tectonic model of Umtanum Ridge in light of the geologic map and cross-section of the Golder Report (Fig. 2N-ll and 2N-13) suggesting normal faulting on Umtanum where reverse arrows are shown.
(Contact:
Tim Hait,
- USGS, 303-234-4697, or Ina Alterman, GSB, 301-492-7856).
Describe the uniqueness of Toppenish Ridge that lead you to conclude that an earthquake (or earthquakes) like that which produced the young scarps on Toppenish Ridge is unlikely to occur on other folds closer to the site (Contact Richard McHullen, GSB, 301-492-4415).
Can a case for segmentation similar to that made for Umtanum-Gable t3ountain (Golder Associates Inc.,
1981) be made regarding other folds near the Pasco
- Basin, such as the Yakima Ridge fold'?
Discuss the bases for your response'Contact Richard tlcHullen, GSB, 301-492-4415).
Provide a summary of all prominent structures (other than those incorporated into f360.14 as part of the CLEW) in the site region, discussing in detail their character and capability with supporting evidence for your judgement.
If you determine any to be segmented, provide a map on topographic base delineating the segments and discuss in detail the character and capability of the individual segments with supporting bases.
(Contact Ina Alterman, GSB, 301-492-7856).
Provide the letter report and lineament maps from C. Glass to WPPSS concerning his aerial reconnaissance of Toppenish Ridge.
