REQUESTS FOR ADDITIONAL GEOLOGIC INFORMATION PALO VERDE NUCLEAR GENERATING STATION, UNITS 1, 2 AND 3 ARIZONA PUBLIC SERVICE COMPANY DOCKET NOS.

STN 50-528/529/530 Eberly and Stanley's (1978) paper addresses the structural geology in the site vicinity (within five to ten miles).

Discuss the impact (and validity) of their interpretation of the subsurface with respect to:

a.

The existence of mountain-basin bounding faults in the Arlington-Gillespie Dam area.

b.

The validity of their interpretation of the site vicinity geologic structure as shown on their Figure 8, p. 933.

c.

The significance of Eberly's and Stanley's interpretation with respect to site safety.

I Describe your 'post-1978 Palo Verde.4 and 5 PSAR activities with respect to the geologic.and seismological updating of the Palo Verde 1,'

and 3 FSAR.

Figure 2 (page

6) of a November, 1979 Dept. of Energy report shows two inferred faults in the Hassayampa Plain northeast of the Palo Verde site.

Discuss the validity of these faults and their site-safety significance.

The DOE report is titled "Geothermal studies in Arizona with two area assessments (DOE/ID/12009-T4)".

Describe the basis used for categorizing the fault (see FSAR Fig. 2.5-6) in the Sand Tank Mountains area some 36 miles SE of the Palo Verde site as older than 500,000 years.

Detai led geophysical surveys (gravity and magnetic) recently-conducted by C; Cloran (Geophysics, Hydrology and.Geothermal Potential of the Tonapah Basin; Maricopa County, Arizona, MS Thesis, Arizona State University, May, 1977) within five. miles of the Palo Verde site indicate that the Tonapah Basin. is bounded by normal. faults.

Discuss the impact of Cloran's interpretation of the subsurf'ace with.respect to:

<<2-a.

Site safety b.

The capabi lity (or non-capability) of the basin-bounding faults suggested by Cloran.

c.

The validity of the structural interpretation of the Tonapah Oesert area as shown on FSAR figure 2.5-8 and other related FSAR figures.
