1he IE inspector toured the site to observe activities in progress which were authorized by the Limited Work Authorization issued
.luly 26, 1978. During the site tour, the IE inspector observed an anomaly in a soil formation in the vicinity of the Unit 1 reactor location that was exposed during trenching of the main excavation area. The IE inspector reported the anomaly to the RIV office which arranged for a site visit by the Rll geologist. His findings are described in paragraph 4 of this report.

3. Review of Personnel Qualifications The IE inspector reviewed records to ascertain whether Public Service Company of Oklahoma (PS0) QA/QC personnel training, experience and qualifications were in accordance with PSAR commitments to Regulatory Guide 1.58 and requirements contained in Sections 17A.l.2.5 and 17 .6 of the PSAR as implemented by Section 2 of the Quality Procedure Manual (QPM) and Section 2 of the Quality Field Procedure Manual (QFPM). Personnel whose records were reviewed included twelve mem-bers of the PS0 corporate QA staff, three members of the Black Fox Station (BFS) site QA staff, and eight members of the BFS site QC staf Qualifications of the Manager, Quality Assurance; the site Quality Assurance Superintendent; and the Superintendent, Quality Control were found to be consistent with the requirements stated in Section 17A.l.2.6 of the PSAR. Other QA/QC personnel were either qualified, or, as in the case of recent hires, in the process of being qualified in accordance with Section 2 of the QPM or Section 2 of the QFPM as applicable. The IE inspector observed that five members of the cor-porate QA staff, three members of the site QA staff, and six members of the site QC staff had experience in nuclear QA/QC activities prior to joining PS No deviations were identifie . Subsurface Preparation - Unusual Problem, Unit 1 The IE inspector observed several anomalies in the walls of nine explor-atory trenches dug in the area of the Unit 1 power block foundatio Geologic units visible in the trenches (seven. extending east-west and two extending north south) were (bottom to top): Pennsylvanian age (300 + million years old), Savanna formation which consisted of interbedded shale and siltstone with a 1-1/2 foot coal seam (drywood coal) underlain by a few feet of under-clay in the upper part of the formatio Quaternaryterraces(700,000 years old, paleomagnetic dating, SER, page 2-24) comprising silty clays with some sand and gravel.

Anomalies observed by the IE inspector were: Downwarp in the Drywood Coal This anomaly was discussed in the PSA It is expressed by a sag in the drywood coal with an amplitude of about 8 feet and a wave length of about 130 feet. The axis of the sag extends in a north-south direction along a line about 30 feet east of the Unit 1 north-south centerline. It extends through the north foundation excavation with a decreasing amplitude and pinches out about 100 feet south of the east-west centerlin The sag does not appear to extend into the underlying shales and its trough is filled with horizontally bedded carbonaceous shale Horizontal Offset in Drywood Coa _1 This feature is located about 40. feet west of the unit 1 north-south centerline and its trace extends in a north-south direction across the foundation excavation. The feature is expressed by an upsqueezing of the underclay with a 10 foot horizontal offset of the coal and a 2 foot drop of the hanging wall on the west side of the upsqueezing. The drop is along a slip plane dipping 17 degrees west. The slip plane is visible in the overlying car-bonaceous shales, but is not readily visible in the underclay, Minor fertical Offsets These features are expressed by tm> 4-6 inch offsets in the car-bonaceous shales above the coal seam about 200 feet west of the north-south centerline. The features die out in a northerly direction and do not appear to extend into the underlying drywood coal. The features observed by the IE inspector appeared to have limited vertical and horizontal extent and appeared to be a result of penecomtemporaneous soft sediment deformation. Features similar to those observed by the IE inspector are described in geologic literature a ; conmon in Pennsylvania age shale, siltstone, sand-stone and coal sequences of the type found at the sit Discussions 'with responsible engineers and geologists, and observation of ongoing work activities verified the anomalous features are being ttudied and documented by the applicant. A written report on these features will be submitted by the applicant to the NRC for revie No deviations were identifie I
5. Exit Interview The IE inspector met with applicant representatives (denoted in para-graph 1) at the conclusion of the inspection on September 29, 197 The IE inspector summari::ed the purpose and' scope of the inspection and the finding ___
