T Question 231.1WC: Prepare a new figure (or revise an existing figure) locating the noncapable shear zones, shear planes, and faults mapped at the site and described in the FSAR (page 2.5-102). Also prepare a table listing the above deformations, the site location.of the deformation, and the Dames & Moore report where the deformation mapping and description appears.

Response

The following figures have been prepared as index maps for locating, by number, the noncapable deformation features described in the FSAR: Figure 231.1-1: Location of Deformation Zones e Beyond Plant Area - Heumader Shale Member; e Figure 231.1-2: Location of Deformation Zones - Power Block - Heumader Shale Member; e Figure 231.1-3: Location of Deformation Zones - Circulating Water System and Northwest ParL of Essential Service Water System - Heumader Shale Member; and e Figure 231.1-4: Location of Deformation Zones - ) Southeast Part of Essential Service Water System - l Heumader Shale Member.. l Table 231.1-1 identifies these zones of deformation by number, the location of each feature, and the appropriate 1 Dames & Moore report containing detailed geologic maps and l deccriptions.

Question 231.2WC: A number of lineaments, other than ti.o s e numerically identi-fled, are shown in Coffey County (the site county) on FSAR Figures 2.5-14a and 2.5-14b. Identify these unnumbered lineaments and present your interpretation of the origin /cause of each. Include in your discussion the relationship, if any, between each.of the Coffey County lineaments (including those presently shown on FSAR Figures 2.5-14a and 2. 5-14 b) and the folds and faults identified on FSAR Figures 2.5-15 and 2.5-16.

Response

All of the lineaments shown in Coffey County on the LANDSAT lineament map of eastern Kansas (McCauley and others, 1978) are discussed below. These lineaments are identified by number and shown on Figures 231.2-1 and 231.2-2. The LANDSAT lineament map was compared with the following references: e State geological map (Jewett, 1964); e Kansas state base map (U.S. Geological Survey, 1963); e Aeromagnetic map of eastern Kansas (Yarger and others; FSAR Figure 2.5-9); !e Bouguer gravity map of southeastern Kansas (Yarger and others, 1981); o Configuration of the Precambrian surface (Cole, 1976); e Geologic map of the Precambrian basement (Bickford and others, 1979); e FSAR Figure 2.5 Regional Fold Map; and e FSAR Figure 2.5 Regional Fault Map. On the basis of this comparative analysis, all of the LANDSAT lineaments in Coffey County appear to be geomorphic in origin. Whereas this analysis has determined that these lineaments

do not correspond with the location of documented folds or faults; anomalously straight segments of stream channels may be controlled by a locally well-developed joint system. Closely-spaced joints often result in preferential erosion of a linear stream segment. As discussed in Section 2.5.1.1.5.1.18 of the Wolf Creek FSAR, Lineament No. 1 is a portion of the "Neosho Lineament" ~ (Wilson,.1979). A 29-mile long segment, southeast of the site in northeastern Woodson County, appears to coincide with trends in magnetic intensity contours (Figure 2.5-14a). Lineament No. lA is a portion of the Neosho Lineament exten-ding from Emporia, Kansas to John Redmond Reservoir, west of 4 the site. This lineament is defined by the channel of the l Neosho River and has no signature on the aeromagnetic map. Part of Lincament No. lA coincides with an intense gravity. low wes of the site, but the lineament also cross-cuts the Bouduer gravity contour lines. This gravity low does not coincide with the aeromagnetic contours, and geophysical evidence for basement control of this lineament is not convincing. As noted in the FSAR, the "Neosho Lineament" is not visible on the map of the Precambrian surface or on structure contour maps of overlying marker beds. The "Neosho j Lineament," therefore, appears to be geomorphically, rather than structurally, controlled. 1 l-l L

A3 noted in the FSAR, portions of Lineaments No. 1 and No. 26 in Woodson County appear to coincide with contour trends on the map of the Precambrian ' surf ace. This trend appears to be partly coincident with the soutnwestern and northeastern flanks of th e Neosho Falls Dome. Lineament No. 26 ir a relatively straight segment o# the Neosho River channel between the confluence of Turkey Creek,. the South Fork, and the Neosho River, southwest of LeRoy, and the town of Iola. It is conceivable that parts of these lineaments are controlled, by closely spaced joints. Structure contour maps of overlying sediments show no evidence of faulting. Lineament No. 35 corresponds dch a southeast flowing tribu-tary to the South Fork of the Neosho Rivet. This stream cuts through upland terrace deposits of chert gravel alluvium into bedrock. This lineament is geomorphic in origin. Parallelism with aeromagnetic contours appears to be fortuitous. Lineament No. 36, in south-central Coffey County, corresponds with the nor th eas t flowing South Fork of the Neosho River. t l According to the geologic map of Kansas, the northwest bank of the stream appears to be composed of more resistant limestone in one area and chert-gravel alluvium in another segment. The portion of Lineament No. 37 in Anderson County appears to coincide with a drainage divide between Kenoma and Elm Creeks, l. l

northwest of Harris, Kansas. This-drainage divide, appears to project' northwestward into Coffey and Osage Counties. ' Lineament No. - 38 coincides with a northwest-to-southeast flowing tributary to Pottawatomie Creek. Lineament No. 39 trends northeast-southwest. The southwestern portion, west of Sharpe, corresponds with southward flowing Long Creek. T1.e stream is flowing parallel to the-strike of rocks belonging to the Shawnee Group. Northeast of Williamsburg, the stream is located adjacent to a cuesta formed by the more resistant Toronto Limestone Member of the Shawnee Group. l I Lineament No. 40 ctrresponds, partly, with northeastward flowing Long_ Creek and, partly, with a tributary to Long Creek. A steep stream bank is underlain by relatively more res11 tant Lecompton Limestone (O'Connor, 1955). I Lineament No. 41 corresponds with Long Creek and an eastern trib' tary to Long Creek, west of Burlington, Kansas. At this u l location, the stream is flowing at the base of a cuesta f underlain by Toronto Limestone. This erosional scarp marks the contact between the Shawnee and undt. lying Douglas Groups. Lineament No. 42 corresponds with Turkey Creek, which is a l northeast flowing tributary to ' the Neosho River. This I lineament also appears to F -- geomorphically controlled. i i l I i

Lineaments No. 43 and No. 44 appear to be erosional in nature and partly controlled by streams flowing along the base of -limestone supported banks. Lineament No. 45 appears to correspond with a linear drainage divide northeast of Ottumwa. Curvilinear No. 46 can be divided into three sections. The southwest portion corresponds with Long Creek, west of Burlington, Kansas. The southern portion is formed by the Neosho River near the town of LeRoy. The eastern portion is formed by Indian Creek. References not cited in FSAR United States Geological Survey,

Question 231.3WC: Expand the LANDSAT lineament presentation (Revision 4, July 1981) to include a discussion of the re7ationship between the lineaments discussed, folds and f aults (FSAR Figures 2.5-15 and 2.5-16), Precambrian surface folds and_ faults (FSAR Figure 2.5-14b),. and earthquake epicenters.

Response

Previous Question 231.2WC and the response address the occurrence and origin of LANDSAT lineaments within Coffey s County (the site county), Kansas. Nine lineaments discussed in FSAR Section 2.5.1.1.5.1.18 appear to be structurally controlled (two folds, seven faults). In addition, several other lineaments appear to correspond with folds and faults shown on FSAR Figures 2.5-15 and 2.5-16. These lineaments are i identified on Figures 231.2-1 and 231.2-2. Lineaments No. 2 and No. 9 correspond with the Abilene Antic line (Fold No. 6-Figure 2.5-15 and Table 2.5-3). The Abildne Anticline is located above a topographically high area on t'ne Precambrian surface close to the geophysical maxima reflecting the Midcontinent Geophysical Anomaly. Lineament No. 5 corresponds with Fold No. 33 and Fault No. 24 (FSAR Figure 2.5-15, Table 2.5-3; Figure 2.5-16, Table 2.5-10). The northwest trending Cedar Creek syncline overlies a graben in the Precambrian surface (see FSAR Section 2.5.1.1.5.2, page 2.5-34).

l Lineaments No. 3 and No. 10 correspond with segments of the 1 Humboldt fault zone (Fault No. 2 Figure 2.5-16, Table 2.5-10). Lineament No. 3 corresponds with a steep slope on the Precambrian surface (eastern margin of Nemaha Uplift). Lineament No. 10 corresponds with a trend on the aeromagnetic map. Lineament No. 32 corresponds with Faults 25 and 30 (Figure 2.5-16, Table 2.5-10) and reflects part of the Humboldt fault zone. Lineament No. 55 may reflect Fault No. 16 (Figure 2.5-16, Table 2.5-10), part of the Nemaha Uplift system of faults (see FSAR Sections 2.5.1.1.5.1.9 and 2.5.1.1.5.2). Lineament No. 31A, in Wabaunsee County, corresponds with Fault No. 20 in the Precambrian surface (FSAR Figure 2.5-16, Table 2.5-10), which trends northwest across the ilumboldt fault zone. I Line$ ment No. 28 corresponds partly wiith a depression in the Preciembrian surface and is located close to a possible northwestward projection of the Eldorado Springs North fault zone (Fault No. 69 FSAR Figure 2.5-16, Table 2.5-10; and Section 2.5.1.J.5.2, page 2.5-34). Lineaments Nos. 47 and 48 may correspond to the axis of the Brownville Syncline, the deepest portion of the Forest City Basin (Fold No. 5 - FSAR Figure 2.5-15, Table 2.5-3). Lineament No. 49 corresponds with Fold No. 21 and Fault No. 22 (FSAR Figure 2.5-15, Table 2.5-3; Figula 2.5-16,' Table 2.5-10). This lineament reflects k

the northeast trending John-Creek Anticline, which is part of the faulted east flank of the Alma Anticline. Lineaments Nos. 50, 51, 52, and 53 may be related to the northeast trending Reese, Beaumont. Countryman, and Winfield anticlines,

spectively 'Folos Nos. 44, 45, 63, and 57, respectively -

FSAR Figure 2.5-15, Table 2.5-3). These folds occur in sedimentary rock above the basement, have been mapped at the surface, and mapped in the subsurface using structure contours. Curvilinear 54 coincides with the location of the northwest trending Florence-Urshel anticline in Marion County (Fold FSAR Figure 2.5-15, Table 2.5-3). Curvilinear 56 No. 29 appears to be related to unnamed faults shown on structure contour maps of Silurian-Devonian "Hunton" rocks (Merriam & Kelley, 1960) and on top of Mississippian rocks (Merriam, 196 ). These faults, however, are not visible on the i structural contour map of the base at the upper Pennsylvanian Kansas City Group (Watney, 19,' 8 ). (Also see FSAR Figure 2.5-16, Table 2.5-10. The 1867 MMI VII Manhattan, Kansas earthquake may have occurred along a fault in the basement beneath, or adjacent to, the Abilene Anticline (see FSAR Figure 2.5-64 and Sections 2.5.1.1.5.1.15 and 2.5.2.1). There is no evidence to relate this earthquake to either Lineament No. 2 or No. 9. In fact, J

J DuBois and Wilson have relocated the epicenter of this event eastward to the vicinity of Wamego-(see FSAR Section 2.5.2.1). Most of the significant earthquakes within 200 miles of the site can be associated with the Nemaha Uplift or the adjacent Central North American Rift System (FSAR Section 2.5.2.3). FSAR Figures 2.5-6 and 2.5-75 indicate that many of these earthquakes are associated with the east or west flanks of the Nemaha Uplift. Although these zones appear to be seismogenic, there is no evidence, to date, relating epicentral locations to any particular lineament. Other earthquake epicenters shown on FSAR Figure 2.5-64 cannot be related with any degree of certainty to a particular LANDS.~.T lineament. e

Ouestion 231.4WC: Please provide a copy of the Dames % Moore report (s) dis-cussing and portraying the Saddle Dam.IV faulting. These reports are referenced in the D&M Second Interim Report of July 1979 (Dames & Mo o re', 1977; 1978a). Also provide a copy of the report (s) which includes-the geologic map (and accompanying description) of the Drum Building excavation.

Response

The Dames & Moore Second Interim Report of July 1979 includes dot ariptions and geologic maps concerning faulting in the foundation excavation for Saddle Dam IV (pages 18-19; Figures 11, 12A, 12B, and 12C). The reference "(Dames & Moore, 1977; 1978a)" refers to reports containing discussions of similar noncapable deformation features, occurring within the Heumader Shale Member, mapped in the Power Block excavation. The geologic map and description of the foundation excavation for the Drum Storage Building is provided in the Dames & Moore Fina Report of August 1981 (Dames & Moore, 1981; Figure 4-A). / References Used in Response to Question 231.4WC Dames & Moore,
