1.0 PURPOSE This report addresses the slope mitigation basis, analysis, and design criteria for possible earthquake-induced rockfall at the PG&E Diablo Canyon ISFSI. Figure 1 shows the location and layout of the ISFSI and hillslope that was evaluated for rockfall hazard and mitigation design. The rockfall evaluation was performed to provide additional information regarding the design basis for a rockfall catchment fence that will be constructed above the ISFSI to mitigate possible rockfall hazard.

The rockfall evaluation was performed by William Lettis & Associates, Inc. (WLA) under Pacific Gas &

Electric Company (PG&E) Contract Work Authorizations Nos. 1223-92 and 1223-93. Specific tasks included:

Review of the SAR and supporting documents;

Development of rockfall models and input parameters;

Rockfall analysis using the RocFall and CRSP computer programs;

Compilation and review of rockfall mitigation approaches; and,

Preparation of this memorandum.

The rockfall evaluation was performed by Jeff L. Bachhuber, C.E.G., and Charles M. Brankman, R.G. of WLA, with modeling assistance from Sean Sundermann of WLA. Internal WLA review was performed by Dr. William R. Lettis, C.E.G. Dr. Joseph Sun and Dr. William Page of PG&E Geosciences Department provided technical review and project oversight.

The following attachments provide the results from our rockfall analysis, backup design information, and case studies for the proposed rockfall catchment fence.

However, because the ISFSI is a sensitive nuclear facility, specific rockfall mitigation is included in the ISFSI design to provide a high level of safety against these low probability events.

Potential rockfall could occur from two sources: (1) random small, loose rock blocks present on the face of the slope, and (2) rock blocks and slabs detached from the overthrust toes of possible rock slide masses that move over clay beds that locally dip out of the slope above the ISFSI. These are discussed below.

Random blocks on the face of the slope that are potentially susceptible to rockfall are typically between 1-to 2-feet in maximum dimension. These rocks include loose blocks on the face of the slope left by past construction (1971 borrow activities) or exploration on the hillslope, and dilated surficial blocks on the surface of bedrock outcrops. These blocks currently are stable under static conditions, and have not moved during past periods of heavy precipitation. No past rockfall has been noted at the site from these WLA DCPP 1223-092 RockFall All I April 30, 2003

sources, suggesting that they would require strong ground shaking to initiate rolling. Because these rocks are inherently stable under present conditions, and because significant shaking would be required to initiate rolling, the random small blocks would likely roll slowly down the slope with little bouncing.

Such rocks probably would be easily and quickly stopped by the tower access road bench, and by interaction and friction between the rock and the slope. The impact energy from the small random blocks on the slope would be much less than the energy from larger rocks released from the toes of bedrock sliding overthrusts, and therefore do not control mitigative design.

The other potential source of earthquake triggered rockfall is detached blocks from overthrust toes of large sliding masses over clay beds. The toe overthrusting could destabilize larger rock blocks (on the order of about 2- to 3-feet, and possibly up to 6-feet in maximum dimension) formed by intersecting joints that currently are keyed-into the rock mass in a stable configuration under present conditions. The overthrust portion of the rock, and the jointed rock imrnediately behind the overthrust, could be free to move out of the slope to form a rockfall hazard. Three potential slide masses were modeled during past ISFSI studies that conservatively bracket possible rock mass movements over clay beds in the bedrock:

Models 1, 2, and 3 (Figures 2 through 4). These possible rock mass movements are low-likelihood events that represent worst-case slope movements during the design basis earthquake, and only could occur considering a number of conservative assumptions regarding clay bed thickness and lateral continuity, strength, and earthquake loading on the rock mass. As presented in the Safety Analysis Report (SAR; October, 2002), potential maximum rock mass displacements along clay beds in the hillslope during the design-basis earthquake range from 1 to 3 feet on the natural slope above the ISFSI cutslope, and from I to 2 feet on clay beds inferred to daylight at the cutslope mid-slope bench and toe. Potential hazards to the ISFSI from seismically-induced slope movements include rockfall from the overthrust toe region of the modeled rock slide mass models that daylight above, or in, the ISFSI pad cutslope (Figures 2 and 3),

and localized heaving and deformation in the toe region of the deepest clay bed slide mass models that daylight at the base of the ISFSI cutslope (Figure 4) (SAR Sections 4.2.1.1.9.2). The geometry of the overthrust slide mass toes and rock mass jointing provide constraints on the potential size and shape of rockfall, as discussed below. The potential overthrust toes could generate larger rocks than the random loose rocks on the hillside discussed previously, and also would tend to have greater initial rotational velocities and horizontal trajectories. Therefore, the overthrust toe rockfall source is the controlling source for the ISFSI rockfall mitigation.

The modeling considered rockfall initiation at the four daylighting locations of the potential clay bed sliding overthrusts (Figures 1 through 5). These locations also conservatively bracket the possible locations of random rockfall from small blocks on the face of the slope, which are relatively insignificant in terms of inertial energy in comparison to the overthrust rockfall.

3.0 BASIS FOR EARTHQUAKE-INDUCED SLOPE MOVEMENTS The basis for mitigation of seismically-induced slope movement includes the results from the ISFSI site geologic investigations summarized in Calculation Package GEO.DCPP.01.21, the results from the clay bed slope stability and defornation analysis summarized in Calculation Package GEO.DCPP.01.26, and the results from wedge sliding pseudostatic stability analysis of the ISFSI cutslope presented in Calculation Package GEO.DCPP.01.23. The analyses of rockfall hazard, and design criteria for rockfall mitigation, are described in the following sections.

Based on the geologic characterization of the ISFSI site presented in GEO.DCPP.01.21, seismically-induced slope movements would be localized along clay beds in the dolomite and sandstone bedrock.

Results from the site investigation were used to determine the locations and geometries of clay beds in the ISFSI site area, and to define possible slide mass models for the slope stability and deformation analysis WLA DCPP 1223-092 RockFall All 2 April 30, 2003

(Figures 2 through 4). The modeled slide masses have basal failure planes along identified clay beds in the rock mass, and are bounded in the upslope direction by stair-stepping tensional detachment zones that break up from the clay beds through the jointed rock. Calculation Package GEO.DCPP.0 1.21 describes the procedures and basis for development of the rock mass slide models. The rock mass slide model failure planes were previously developed and analyzed for Section I-I' (Figures 2 to 4). For rockfall analysis of Section A-A', the locations of the rock mass models and basal clay zones were extrapolated from Section I-I' with consideration for the bedding dip direction and magnitude (Figure 5). We note that it is possible that the clay beds do not extend laterally between Sections I-I' and A-A'; therefore, the assumption of clay bed continuity is conservative. Because bedrock bedding dips westward, the clay bed locations were projected updip and occur at a higher elevation in Section A-A'.

The stability and deformation analyses performed in Calculation Package GEO.DCPP.01.26 provide calculated slope deformation magnitudes for the clay bed slide mass models for the design-basis earthquake loading conditions. The calculated earthquake-induced slope movements involve translation of the rock slope as a relatively coherent block over the clay beds with relatively little internal disruption and deformation within the sliding block itself. As a result, the rock mass movements are localized along the sliding block margins, and would result in the formation of a linear zone of cracking and settlement at the headscarp tension crack, and overthrusting of rock at the toe of the sliding mass above the clay bed.

The locations of clay bed daylighting/overthrusting locations are shown on Figures 2 through 5. The overthrust toe region would be susceptible to calving and progressive raveling of detached rock blocks, and represents the primary source of earthquake-generated rockfall and potential hazard to the ISFSI.

Calvedlraveled blocks in the overthrust lip would detach from the rock mass along pre-existing, steeply-inclined joints that sole out and daylight in the overthrust zone, or that exist directly behind the overthrust lip. The size of the calved and raveled rocks from the overthrust toe region would be controlled by the size of the overthrust lip (between 1 and 3 feet; Figure 6), and the joint spacing in the rock mass which averages between 1 and 3 feet (Figure 7) as described in SAR Section 2.6.5.2.2. Based on these calculated ranges of displacements and rock mass joint spacing, likely maximum dimensions of rock blocks that could be dislodged from the clay bed overthrust regions are between 1 and 6 feet, with a most-likely range of between 1 and 3 feet. The geometry and size of possible blocks released at the slide overthrusts is discussed in Section 4.4.3.

Calculation Package GEO.DCPP.01.23 presents the basis for the ISFSI cutslope design and slope stabilization. Design parameters were developed for a rock anchor support system (30-foot long post-tensioned rock anchors on 5-foot centers, and wire-mesh-reinforced shotcrete) to maintain the static and dynamic stability of the 70 degree cutslope. The rock anchor support system is designed to provide direct support to the face of the ISFSI cutslope, and to reinforce the rock mass in the potential stress-relieved zone that will develop directly behind the cut in response to excavation. The rock anchor design will be locally modified, as needed, to address possible lower-strength friable rock zones that may be encountered in the cut excavation. The cutslope rock anchor system is not intended to resist the potential large-scale bedrock mass sliding. However, the toes of slide mass models 3a, 3b, and 3c daylight in, or at the base of, the rock anchor-reinforced cutslope (Figure 4). The basal plane for slide mass Models Nos.

3a and 3c toe-out below the cutslope anchors. The basal plane for slide mass model 3b toes-out at the back of the cutslope mid-slope bench, and projects through, or between, one or two rows of anchors.

Because the rock slope failure mode involves planar translation over the clay beds with little internal deformation, the rock anchor reinforced cutslope and supported rock mass should be able to accommodate the possible clay bed translation without significant internal disruption or global cutslope failure. The tensioned rock anchors and anchored wire-reinforced shotcrete may experience localized heaving and cracking at the overthrust toe region of the clay bed slide masses, but should still be able to restrain any possible large rock blocks from falling out of the cutslope. The ISFSI pad is set back from the toe of the cutslope a distance of 41 feet. This setback provides a significant buffer zone to catch any possible minor small rockfall or small spalled chunks of shotcrete from the lower part of the cutslope, and WLA DCPP 1223-092 RockFall All 3 April 30, 2003

provides a substantial separation between the pad and zone of possible deformation at the toe-of-slope daylight of slide mass model No. 3a and 3c. In addition, the cutslope includes a 25-foot-wide mid-slope horizontal bench. The significant width of the bench should effectively catch any possible small rocks released from the upper part of the cutslope (above the bench), and also provides a wide buffer zone to accommodate the calculated 1- to 2-foot of displacement for the slide mass model No. 3b that toes-out in the vicinity of the bench location.

4.0 ROCKFALL ANALYSES INPUT AND ASSUMPTIONS 4.1 General The potential hazard to the ISFSI from rockfall was evaluated using state-of-practice evaluation methods (e.g., Federal Highway Administration (FHA); 1994) that include development of topographic cross sections along the rockfall paths, sensitivity analysis of key input parameters such as surface roughness and coefficient of restitution, evaluation of source rock characteristics, and iterative rockfall modeling using the RocFall computer program (Rocscience, Inc., 2002). Attachment F includes two case studies of rockfall analyses that incorporate these elements, and that are similar to the analysis proposed for the ISFSI project.

The RocFall program was selected as the preferred design basis program because of the following:

RocFall was found to accurately model the observed and historic field performance of the ISFSI hillside and typical behavior predicted for slopes of the same inclination by Keefer (1984),

Ritchie (1963), and the Federal Highway Administration (1991);

Verification of the program is well-documented;

RocFall permits probabilistic evaluation and complete sensitivity analyses of variation in the input parameters;

The program was found to be stable with repeatable modeling runs;

RocFall has received wide commercial use; and,

The program has been reviewed by Dr. E. Hoek (Hoek, 2000).

In addition to RocFall, a second rockfall analysis program, the Colorado Rockfall Simulation Program (CRSP), was used to provide additional information and evaluation. However, the CRSP program was found to be less stable than the RocFall program, and the model output was contrary to observed field behavior. The CRSP results appear to be over-conservative with respect to rockfall runout distances, as discussed in Section 5.0.

The analysis approach for development of the input for the ISFSI rockfall modeling is outlined below:

Evaluate past slope performance;

Determine rockfall source locations and mechanics;

Develop detailed topographic cross sections along rockfall paths;

Evaluate source rock characteristics (dimensions, shape, hardness);

Evaluate slope characteristics (roughness, coefficient of restitution, vegetative cover);

Develop seismic loading initiation;

Iterative rockfall computer modeling; and,

Review of modeling results and development of mitigative design.

4.2 Slope Inclination and Past Slope Performance The inclination of the hillslope above the ISFSI pad and cutslope is relatively gentle, on the order of about 15 to 21 degrees. Most rockfall occurs on slopes exceeding an inclination of about 40 degrees (Keefer, 1984; California Division of Mines and Geology, 1997), suggesting that the ISFSI hillslope is inherently stable against rockfall. Additionally, rockfall design charts and assessment methods developed by Ritchie (1963), and used by the Federal Highway Administration (e.g., FHA and U.S. Department of Transportation Manual "Rock Slopes"; 1991), predict that rockfalls on slopes with an inclination of less than 30 degrees should roll down slopes without significant bouncing. This suggests that possible rockfall on the hillslope above the ISFSI should roll over the surface with correspondingly low velocities.

No evidence of historic or prehistoric rockfalls were observed on the ISFSI slope area during our review of pre- and post-construction aerial photographs (refer to Calculation Package GEO.DCPP.001-21).

Additionally, no significant rockfalls have occurred on the hillslope since the borrow cut excavation was made in 1971, further suggesting that the slope is not prone to rockfall under static conditions. Rainfall is one of the primary triggers for rockfall (e.g., Hoek, 2000), and the ISFSI hillslope has experienced periods of high rainfall numerous times (e.g., 1982/83, 1996) since the 1971 borrow excavation was completed without observed rockfall events.

During ISFSI site exploration activities, 22 test trenches and a switchbacking drill rig access road were excavated in the slope above the ISFSI cutslope area (Photos 1 and 2; Attachment B). These excavations were made through, and above, the bedrock slide model overthrust locations, and were made with tracked excavators and bulldozers that moved up and around on the hillslope. Thousands of rock blocks in the size range of 6 inches to about 2.5 feet in maximum dimension were excavated from the slope and placed in spoil piles on the slope adjacent to the test trenches and road excavations (Photos 3 through 5).

Occasional blocks larger than 2.5 feet (and up to a maximum of about 4.5 feet) were also encountered during excavation, but these represented less than about 1% of the excavated blocks. Test trench excavation in some cases met refusal in massive, keyed-in rock below a surface veneer of talus and weathered rock. The spoil piles typically had sideslope inclinations on the order of 35 to 45 degrees, and were placed on slopes ranging in inclination from about 15 to 21 degrees. Excavated rock blocks were dumped out of the excavator bucket onto the spoil piles, or pushed into the spoil piles by the bulldozer blade. - During the excavation and equipment movement activities, rock blocks only slightly shifted or stayed in place, and only two out of many thousands of rock blocks were observed to roll farther than a foot or two down the slope. One of these blocks, a 4.5 foot angular block, was dislodged from the slope when pushed downhill by the bulldozer blade, and slowly rolled several tens of feet downhill until it stopped on an inclined slope area. The other rock, a 1 to 1.5 foot subangular block, rolled down the slope several hundred feet before stopping on the inclined slope near the base of the hill in the ISFSI pad area.

Both rocks rolled slowly over the slope surface without bounding. The smaller block rolled farther than the larger block, contrary to typical rockfall behavior where large blocks usually roll farther than small blocks. However, in this case, the small block was a single occurrence from a potential "pool" of thousands of blocks (and represents a small fraction of a percent of available blocks), and therefore does not represent typical behavior. The remaining blocks that were placed in the spoil pilesor that were shifted on the slope during equipment movement, remained in place, even on the steep or spoil pile slopes (Photos 1 and 2). This behavior indicates that loosened angular rocks on the 15 to 21 degree slope above the ISFSI do not tend to roll over the slope, even when pushed or dropped by excavation equipment.

4.3 Topographic Surveys and Analysis Profiles Rockfall modeling was performed using two programs (RocFall and CRSP) on two surveyed cross sections: Sections A-A' and I-I' (Figures 1, 2 and 5). These sections extend upslope subnormal to the proposed ISFSI cutslope, and are oriented parallel to the most-likely direction of earthquake-induced WLA DCPP 1223-092 RockFall All 5 April 30, 2003

slope movements. The topographic surveys, and basis for estimation of the earthquake-induced slope movement directions, are discussed in Calculation Package GEO.DCPP.001.21, rev. 1.

The topography along sections A-A' and I-' were manually checked against the original topographic survey data, and was used to construct detailed slope profiles for input into the RocFall and CRSP computer models. The computer model profiles are included in Attachments C and D. Each of the profiles were constructed with control points at 10-foot horizontal spacings, and include topographic features such as slope breaks, and the tower access road benches.

4.4 Source Rock Characteristics 4.4.1 Rock Block Shape and Hardness The source strata for earthquake-induced rockfall are dolomite (primary) and sandstone (secondary) beds.

Based on site geologic investigations (GEO.DCPP.01.21, rev. 2), the dolomite and sandstone rock blocks are moderately hard to hard, and relatively angular. Rockfall blocks, therefore, would be relatively hard and tend to stay intact without significant breakage and desegregation, and the angular shape of the blocks would tend to resist rolling. The RocFall computer model uses only spherical rock shapes, while the CRSP computer program allows the user to select from three default shapes: spheroidal, cylindrical, and disk-shaped. The angular rock blocks at the ISFSI are better represented in a model by a square or rectangular shape. Therefore, the modeled shapes used in the rockfall modeling are conservative (round for RocFall, and cylindrical for CRSP).

4.4.2 Surface Roughness Surface roughness along the rockfall trajectory path is an important input parameter for rockfall modeling. The slope surface between the rockfall source zones and the ISFSI cutslope location is relatively rough, with a surface irregularity on the order of about 6-inches to 2-feet formed by discrete rock boulders, outcrops, and slope indentations. The rock surface is covered by a thin veneer of rock rubble, and soil in places, that locally tends to smooth out the surface profile to the lower value of 6-inches. The tower access road surface also has a surface roughness of about 6-inches across the width of the road bed.

Values for our modeling of surface roughness were determined by consensus of three WLA geologists by review of detailed photographs of the slope obtained during site exploration (e.g., Photos 3 through 6).

Although the range in surface roughness is from 6-inches to 2-feet, a value of 6-inches was used for the computer rockfall modeling programs. This value is believed to be conservative, and results in overprediction of rockfall rolling distances and impact energies for portions of the slope that are rougher than this value, especially for the CRSP program. Areas that are rougher than the 6-inch value typically are uphill from the tower access road. Surface roughness affects different rock block sizes to varying relative degrees. For example, a 6-inch surface roughness value is /2 the height of a 1-foot block, yet only 1/ 2 0tb the height of a 10-foot block. Correspondingly, the 6-inch surface roughness would tend to inhibit or arrest the rolling of a 1-foot block much more than for the 10-foot block. This size-roughness ratio is automatically accommodated by the CRSP program, and only one value of surface roughness needs to be input. The RocFall program handles the roughness input differently. Roughness is input as an angle deviation from the slope profile. The influence of surface roughness relative to block size was accommodated in the RocFall program by determining the angular ratio between the block and surface roughness using the formula: 0 =tan-'(S/R); where 0 is the differential slope angle, S is the measured or estimated surface roughness, and R is the radius of the rock block.

WLA DCPP 1223-092 RockFall All 6 April 30, 2003

4.4.3 Block Size/Mass The size of a rockfall block is a significant factor that has a high influence on the rolling distance and impact energy. As discussed previously, the size of calved and raveled rocks from the overthrust toe regions of possible bedrock mass movements above the ISFSI would be controlled by the size of the overthrust lip (between 1 and 3 feet; Figure 6), and the joint spacing in the rock mass which averages between I and 3 feet (Figure 7). Photographs of typical rock mass discontinuity spacings from exploratory trenches in the rockfall source zone areas are included in Appendix B. A further basis for determining rockfall block sizes is evaluation of the size of blocks that break out of the rockmass during the excavation of the exploratory trenches and drill rig access road. The excavated blocks typically were between about 6 inches and 2.5 feet in maximum dimension, with the largest blocks up to about 4.5 feet.

Very few blocks larger than about 2.5-feet in dimension were excavated from the slope.

The size of the potential blocks that could be released from bedrock slide overthrusting was evaluated by geometric construction and trigonometry using the slope inclination, inclination of clay beds forming the basal slide plane, and typical joint spacing, as shown in Figure 6. These potential blocks represent the greatest potential rockfall hazard, as described previously in Section 2.0. The overthrust blocks would likely have high height-to-length ratios that are controlled by the thickness of the overthrust lip, and would be triangular to rectangular in cross section (Figure 6). Maximum block heights would be on the order of 2 to 3 feet, and are controlled by the thickness of the overthrust lip (Figure 6). The maximum block width (measured along contour) is controlled by the dominant northwest- to northeast-trending, steep joint sets that are spaced about 1 to 3 feet apart, and impart a fabric in the rock mass. Based on the joint spacing, the maximum block width would be about 3 feet. The maximum block length (measured into-the-slope) ranges between 3 feet (the maximum length of the overthrust) and 6 feet, considering the possibility of widely-spaced slope-parallel joints (Figure 6), and an uphill release surface located at twice the typical joint spacing. Therefore, our calculated upper bound rock block that can be reasonably expected to fall from the overthrust lip based on geologic conditions and slope geometry is an angular (triangular to rectangular) block with the dimensions of 2x3x6 feet, or an equivalent mass of about 5,112 pounds using a typical dolomite and sandstone unit weight of 142 pounds per cubic foot. This geologically-based upper bound block is referred to as the "6 foot" block for the rest of this report, and for rockfall modeling. Because the ISFSI is a sensitive facility, and the approach for rockfall mitigation is a defense-in-depth approach, a larger hypothetical angular block with maximum dimensions of 2.5x5xlO feet was considered in the analysis to check the safety margins for calculated kinetic energy for the upper bound 6 foot block. The hypothetical 2.5x5xlO foot block is referred to as the "10 foot" block for the rest of the report and rockfall modeling. We note that the 10-foot block is not supported by the geologic and slope conditions, and predicted size of bedrock slide overthrust lips, and represents an extreme upper bound rock block that has a very low probability for occurrence. The equivalent mass of the 10 foot block is 17,750 pounds. It should be noted that the typical joint spacing of 1 to 3 feet in the rock mass make it relatively unlikely to form an intact rock block that has maximum lengths exceeding one or two-times the length of joint spacing without breaking up into smaller blocks.

The rockfall modeling programs do not allow input of irregular, angular block shapes, and simplify the rock geometry into equivalent spheres or rounded columns or disks. The equivalent maximum mass for the 6 foot upper bound block relates to a sphere with a diameter of about 4.5 feet diameter, or a rounded column with a diameter of 2.8 feet and length of 6 feet. The equivalent maximum mass for the 10 foot block relates to a sphere with a diameter of about 6.8 feet, or a rounded column with a diameter of 4.0 feet and length of 10 feet. Spherical rocks of diameters between 1 and 10 feet were modeled in the RocFall program to conservatively bracket the possible rockfall block sizes (Table 2). We note that the 10 foot diameter sphere has a mass significantly greater than the previously-described 10 foot angular block.

Three rounded columnar rocks were modeled in the CRSP program to evaluate kinetic energy bracketing the maximum rockfall block masses: columns with a diameter-to-length aspects of 3x3 feet, 3x6 feet, and WLA DCPP 1223-092 RockFall All 7 April 30, 2003

5xlO feet (Table 3). The masses for the 3x6 and 5xlO foot columns significantly exceed those corresponding to the 6 foot upper bound block and 10 foot hypothetical block.

4.4.4 Coefficients of Restitution The interface effects between the rolling or bounding rockfall block and the slope are factored into the rockfall computer models by inputting "coefficients of restitution". Two coefficients of restitution are input: the coefficient tangential t the slope/bounding block, and the coefficient normal to the slope surface. The coefficients of restitution are used to calculate energy loss by non-perfectly elastic collisions between the block and the slope which results in loss of kinetic energy, and corresponding reductions in velocity, bounce height, and impact energies. In general, the harder the slope, the higher the coefficients of restitution. The tangential coefficient determines how much the component of rock velocity parallel to the slope is reduced during impact. Vegetation, and to a lesser degree, rock or soil hardness and composition, influence the tangential coefficient. In a soft slope, the rock block can imbed into, or shear through, the surface materials, reducing the rotational energy of the falling rock, and slowing the rock to a greater degree with respect to a clean, hard surface with a high tangential coefficient of restitution. The nornal coefficient of restitution is a measure of the change in the velocity normal to the slope after impact, compared to the normal velocity before impact. The normal coefficient is determined by the rigidity of the surface. A soft slope with low rigidity and normal coefficient of restitution causes a greater loss of energy during collision, and reduces the bounce height as compared with a hard rock surface.

We assigned different values of coefficient of restitution for two different materials encountered along the analyses cross sections: (1) general slope, and (2) tower access road surfaces. These coefficients were established on the basis of literature review of similar slope conditions and materials (e.g., Hungr and Evans, 1988; Robotham and others, 1995; FHA, 1994; Pfeiffer and Bowne, 1989; and Pfeiffer and Higgins, 1990), and our experience on previous projects. These values have been developed on the basis of rockfall field experiments and modeling case studies. The corresponding values of coefficient of restitution for these materials are presented in Table 1.

The values selected for the general slope are intermediate between values for hard bedrock outcrops and boulders, and talus. This is reasonable because the overall slope is approximately 25% interspersed rock outcrops separated by rock talus, and about 75% rock talus and soil.

4.5 Initial Seismic Velocity The RocFall and CRSP rockfall programs both permit an initial outward velocity for the rockfall blocks to mimic a triggering event such as earthquake shaking or disturbance by excavating equipment. It is common to use an initial starting velocity to initiate movement of the rolling block. Without this initial velocity, some of the models would not initiate rock rolling. For the ISFSI analysis, the initial velocity is used to model a triggering pulse of earthquake shaking. An initial horizontal velocity of 7.5 feet/second were input into the rockfall models. This value is comparable to the maximum calculated peak particle velocity for the 5 sets of rock input motions used for the slope stability analyses, resulting in maximum moving block velocities of 210 centimeters/second (7 feet/second) (J. Sun email correspondence, April 11, 2003). It is noted that the peak velocities usually occur concurrent with the strongest pulses of earthquake shaking, and that the rock overthrusting may lag somewhat in time behind the greatest velocity pulse. Therefore, the use of the 7.5 feet per second initial velocity is a conservative assumption.

The RocFall program also allows for an optional initial rotation velocity to that is superimposed on the horizontal initial velocity to represent a toppling-type initial movement of the rock block. We used an initial rotational velocity of 3 radians/second (approximately 180 degrees/second) to represent an initial topple movement caused by calving of the rockblocks away from the overthrust lip of the theoretical clay bed sliding masses. The 3 radians/second initial rotational velocity is believed to be a conservative upper bound velocity caused by rapid toppling of the overthrust blocks. The rotational velocity of smaller blocks less than 2 feet in height could reach the values used in the modeling, but would likely be considerably less for blocks over about 2 feet in height.

4.6 Rockfall Modeling Methodology 4.6.1 General and Computer Modeling Function Rockfall computer models simulate rockfall events by calculating the rock trajectories along a defined slope. Rockfall events are simulated by rolling test rocks over a user-defined slope model. The programs use Monte Carlo simulations to randomly change the input slope parameters within the prescribed ranges each time the simulated rock contacts the slope. This results in variation of the falling rock trajectory path and energy, artificially simulating field variation in these parameters. The algorithms used to develop the rockfall paths and slope reactions were developed on the basis of rock mechanics theory and field experiments of test rockfalls, and have been verified by comparing the program output against additional field testing and case studies. Multiple rocks are simulated to develop an envelope of rock trajectories, and to calculate statistical variations in trajectory, velocity, bounce height, and energy.

The computer programs allow the user to estimate the rockfall trajectory path, bounce height, velocity, and impact force at selected analysis points along the slope profile. This information is used to develop design criteria for rockfall mitigation measures such as catchment benches or ditches, fences, or walls.

Output from the programs includes a profile of the slope with an envelope of simulated rockfall trajectory paths, and graphs or data tables that present rock velocity, bounce height, and kinetic energy either at user-defined, discrete analysis points, or for the trajectory path.

4.6.2 Softvare. Hardware and Licensing The ISFSI modeling was performed using the RocFall Version 4.037 (Rocscience, 2002) program licensed to William Lettis & Associates, Inc. A separate check of some of the RocFall runs was performed by repeating runs with the same input values and cross section using the Colorado Rockfall Simulation Program (CRSP) Version 4.0 marketed by the Colorado Department of Transportation (CDOT, 2000), also licensed to WLA. Both RocFall and CRSP are standard computer programs that WLA DCPP 1223-092 RockFall All 9 April 30, 2003

include instructional manuals and technical support, and are widely used in industry and by government agencies.

Analysis was performed on a DELL Inspiron model 8000 laptop computer running the Microsoft Windows XP operating. system. The software was purchased by, and is licensed to, William Lettis &

Associates, Inc. (WLA), and all analyses were performed by WLA at their Walnut Creek, California, office. The programs have not been modified from the versions purchased from Rocscience, Inc. or CDOT.

4.6.3 Verification and Program Performance Manufacturer verification of the RocFall program is well-documented in a series of verification reports that are available for downloading from the Rocscience website at www.rocscience.com. Verification of the RocFall program was made by performing parallel hand calculations, and independent checking of the program algorithms. Field testing by the CDOT and California Department of Transportation to calibrate and verify the CRSP program. The field testing results are described in the CRSP manual (CDOT, 2000).

We checked and verified the correct function of the RocFall and CRSP programs by accurately emulating the program output from example programs and tutorials in the program manuals and documentation. An example problem check output for the RocFall program is included in Appendix C. Models, input data, and results were compiled and/or checked by a team of three WLA geologists Jeff Bachhuber, Charles M.

Brankman, and Sean Sundermann. Initial iterative test runs were made on program example and tutorial problems, and the ISFSI slope models, to further test the correct operation of the programs by adjusting the input values to assess the relative impacts of changing these parameters.

We attempted to independently verify the RocFall and CRSP programs by performing parallel model runs with the same input parameters. However, the two programs provided significantly different outputs. For example, the RocFall program calculated that all rock spheres from 3- to 10-feet in size stop within 20 feet of the initiation point. Conversely, using the same models, the CRSP program calculates that all of the 3-foot cylinders, most of the 6-foot cylinders, and some of the 10-foot cylinders roll to the bottom of the slope. Program documentation describes that the RocFall program is particularly sensitive to changes in coefficient of restitution, whereas the CRSP program is especially sensitive to changes in surface roughness. The different algorithms in the programs process the input data in different ways, resulting in the differences in the program outputs. The RocFall program was stable throughout the modeling, and we were able to accurately repeat model runs accounting for slight changes resulting from the randomness imparted by the Monte Carlo simulation and variations in input parameters within the specified ranges.

However, the CRSP program was not always stable, and often would crash in the middle of a run.

Sometimes a model run could be repeated, but other times a model that ran previously would crash during attempted repeats. The final runs were accepted only after at least one repeat could be performed.

5.0 RESULTS 5.1 Overview Analysis cross sections A-A' and I-I' are shown on Figures 2 through 5. The RocFall and CRSP computer program analyses sections and output runs are included in Attachments C and D, respectively.

Tables 2 and 3 show the input values and summarized program output for RocFall and CRSP, respectively. All program runs made with RocFall and CRSP included 1000 separate rocks per run. The trajectory of each simulated rock was varied by the program using the user-defined input values and value ranges that are shown on Tables 2 and 3.

WLA DCPP 1223-092 RockFall All 10 April 30, 2003

RocFall was the primary program used for analysis, and discrete runs were made for rockfall originating point ("seed points") at the theorized overthrust toe locations for slope analysis models la, lb, 2a, and 2b.

All of these seed point locations are on the slope above the proposed ISFSI cutslope and rockfall catchment fence. As discussed previously, the daylighting toe locations for slope models 3a, 3b, and 3c daylight in the cutslope mid-bench, or at the toe of the cutslope, and therefore should not produce potential hazardous rockfall. Each RocFall seed point location was analyzed for spheres of 1, 3, 6, and 10-foot diameter (refer to Section 4.4.3 discussion). CRSP runs were performed for seed point location was analyzed for model 2a and 2b seed point locations that daylight nearest to the ISFSI cutslope and rockfall catchment fence location, both for sections A-A' and I-I'. The CRSP runs were performed for round columns with diameter and length values of 3x3, 3x6, and x10 feet (refer to Section 4.4.3 discussion).

The analysis results for RocFall and CRSP vary significantly, primarily due to differences in the simulation algorithms used to calculate the rockfall trajectory paths. The input slope profiles and material properties were the same for both programs (Tables 2 and 3). None of the modeled spheres from the RocFall program reached the top of the ISFSI cut, or the proposed rockfall fence locations. Conversely, all, or almost all, of the 3- and 6-foot columns modeled by the CRSP program rolled past the top of the ISFSI cut and rockfall catchment fence locations (Tables 2 and 3). Additionally, some of the 10-foot columns in the CRSP runs reach the top of the ISFSI cut location. A fundamental difference between the programs is that larger spheres (greater mass) in the RocFall program tend to roll farther downslope than smaller spheres, but the opposite is true for the ISFSI CRSP runs, in which smaller columns typically roll farther downhill. This is contrary to the CRSP program manual that states that larger rocks modeled by the program should roll farther than smaller blocks (CDOT, 2000).

The RocFall modeling matches the historic performance of the ISFSI slope and rockfall behavior for slopes of similar inclination reported in the literature by Keefer (1994), Ritchie,(1963), and the Federal Highway Administration (1991). However, the results from the CRSP modeling are contrary to the historic ISFSI slope behavior and reported literature. For example, as discussed in Section 5.2, only two rocks rolled a significant distance (over about 1 to 2 feet) during the extensive site exploration trenching and drilling access track construction on the site that generated thousands of blocks that were dumped onto oversteepened spoil piles on the slope. One of these blocks rolled several tens of feet down the hill before stopping, comparable to the predicted response by the RocFall model. The other continued in a slow-rolling mode without bouncing to near the lower part of the slope. If the CRSP modeling was correct, most of the blocks loosened from the slope should have rolled down to the base of the hill. This would be unprecedented behavior for slopes of the same inclination (between about 15 and 21 degrees) reported in the literature.

5.2 RocFall Computer Model Rockfall modeling was performed using the computer program RocFall v.4.037 (Rocscience, 2002) that simulates the bounce paths of rock blocks down a slope, and calculates block velocities and kinetic energies at user specified points along the slope. The RocFall program was developed as a Masters thesis project performed at the University of Toronto, Canada (Stevens, 1998). The program includes algorithms that permit specification of ranges for input parameters (coefficient of restitution, slope angle/roughness, material friction), and performs iterative "probabilistic" calculations that randomly sample the values within the specified ranges. The RoeFall program has been comprehensively verified by the manufacturer, and is widely used by the engineering and transportation industry (e.g., Hoek, 2000).

The program generates numerous rockfall runs using Monte Carlo simulation, and produces a probabilistic distribution of trajectories. The bounce height and energy distributions for the model runs are determined for set calculation points designated on the profile. The RocFall program allows WLA DCPP 1223-092 RockFall All 11 April 30, 2003

probabilistic rockfall evaluation by processing a range of values for slope profile, surface roughness, and coefficient of restitution (Rn and Rt) that the user inputs for each slope segment of the model profile.

These values are varied for each simulated rock and for each impact point, imparting a radomness that affects rock trajectory and velocity and emulating actual field conditions.

The results from the RocEFall analysis are shown in Table 2. Prior to production runs, numerous test iterations were made with the program to evaluate the effects of changing the following input parameters:

initial velocity, slope roughness, and coefficients of restitution. The iterative testing showed that the RocFall model was primarily sensitive to changes in initial velocity and coefficients of restitution (for large changes in values such as Rn from 0.3 to 0.45, or Rt from 0.80 to 0.95). However, the model results did not change significantly when the values were kept within reasonable ranges for the SFSI slope and material conditions.

The simplified sphere dimensions are very conservative for modeling purposes, and still did not reach the ISFSI fence location from the overthrust toe locations, as described below. Because of these results, the size of the spheres were not adjusted (reduced) to reflect equivalent masses that more accurately reflect the masses of likely rockfall blocks. This is conservative, as the spheres with the greatest mass roll farthest down the slope and have the greatest impact energies.

Thirty two model runs were made with the RocFall program, sixteen each on sections A-A', and I-I'.

The RocFall modeling shows that none of the 1000 rocks simulated per run would reach the top of the ISFSI cutslope and proposed rockfall catchment fence location (Table 2). After initiation of rolling by the initial 7.5 ft./sec. horizontal force combined with a 3 radians/second initial rotational force, the rocks roll between 1 and 17 feet downslope before stopping either on the tower access road, or the slope (Table 2).

In general, the larger spheres tended to roll farther than the smaller spheres, but still stopped far short of the proposed catchment fence location. Test iterations made prior to production runs showed that changing the coefficients of restitution did not significantly change the program results.

The RocFall modeling matches the observed field performance as discussed in Section 5.2, and suggests that no rocks would reach the proposed rockfall catchment fence location at the top of the ISFSI cutslope.

During their short trajectories, the simulated rocks had low bounce heights (less than about 1 to 3 feet),

and quickly lost energy from the initial outward acceleration by friction and slope interaction.

5.3 CRSP Computer Model In order to provide a second method to assess rockfall behavior on the ISFSI slope, we used the computer program CRSP (Colorado Rockfall Simulation Program), version 4.0 (CDOT, 2000). The CRSP program was originally developed as a Masters Thesis project at the Colorado School of Mines (Pfeiffer, 1988),

and has been subsequently modified and adopted by the Colorado Department of Transportation based on calibrations by field testing. This program has had wide application for highway design and evaluation projects, however the results are often reported to be conservative (e.g., CDOT, 2000). Similar to RocFall, CRSP calculates the bounce trajectories and impact energies for rock blocks of set sizes down the modeled slope. The program generates numerous rockfall runs using Monte Carlo simulation, and produces a probabilistic distribution of trajectories. The bounce height and energy distributions for the model runs are determined for set calculation points designated on the profile. A key difference between the CRSP and RocFall programs is that the programs process the slope roughness input differently. The manner in which the CRSP program processes the slope roughness was found to be conservative.

As described in Section 4.1, the CRSP program was found to be less stable and reliable than the RocFall program, and the modeling results are contrary to observed and historic slope performance. Additionally, the CRSP model predictions also do not match typical slope performance for similar slopes (similar inclination, height, and materials) described in the literature (e.g., Keefer, 1994, Ritchie, 1963).

WLA DCPP 1223-092 RockFall All 12 April 30, 2003

However, because all rocks modeled by the RocFall program did not reach the fence location, we needed to use the CRSP program to evaluate possible impact energies at the fence location associated with very low probability rockfall events that possibly could reach the fence. The CRSP program calculated numerous rocks to pass the fence location, as described below. We believe that our approach using the CRSP program to estimate rockfall catchment fence design capacities at the ISFSI site is conservative, and the CRSP-based impact energies therefore represent extreme, worst case events that require multiple conservative assumptions to occur.

The CRSP program was used to repeat the analysis runs for rockfall generated from the most critical slope failure models 2a and 2b on both cross sections A-A' and I-I'. The results from the CRSP modeling are shown in Table 3. Material properties and slope profiles used for CRSP were the same as input for the RocFall program. Rockfall blocks were modeled as cylindrical columns that bracket, and exceed, the equivalent masses for maximum predicted rock sizes described in Section 4.4.3: (1) a smallest cylinder with a diameter and length of 3 feet (2) a mid-size cylinder with a diameter of 3 feet and length of 6 feet; and, (3) a hypothesized maximum cylinder with a diameter of 5 feet and length of 10 feet. The 3x3 foot cylinder best reflects the most likely maximum block that could be shed of the hillslope, and the 3x6 foot cylinder is believed to conservatively capture the upper bound, geologically-reasonable block size. The 5xlO foot cylinders results need to be reviewed critically and with the understanding that the mass of these cylinders greatly exceeds any likely rock block mass that could be generated on the ISFSI hillside.

Six CRSP model runs were made for rockfall initiation points at the toe of each slope models 2a and 2b:

three pairs of analyses for cross section A-A', and three pairs for cross section I-I' (Table 3). Similar to the RocFall program, 1000 rocks were simulated for each CRSP run.

The CRSP analysis shows that one hundred percent of the modeled 3x3 foot cylinders reaches the top of the ISFSI cutslope/rockfall catchment fence location for all initiation points. The 75h and goh percentile impact kinetic energy for these cylinders ranges between about 11 and 25 foot-tons, and 12 to 28 foot-tons, respectively (Table 3). Ninety nine to one hundred percent of the 3x6 foot cylinders also rolled to the top of the ISFSI cutslope. The 75th and 90"' percentile impact kinetic energy for the 3x6 foot cylinders ranged between 33 and 81 foot-tons, and 35 and 84 foot-tons, respectively. The 84 foot-ton energy value is believed to be a reasonable maximum value for the upper bound rock block that could be released from the hillslope above the ISFSI during a seismic event.

As discussed in Section 4.4.3, a very low probability hypothesized extreme rockfall block with a mass of 17,750 pounds was modeled by a cylinder measuring 5xlO feet. This "extreme event" cylinder is used as a basis of comparison against the calculated energies for the upper bound 6-foot block to ensure a high margin of safety for the rockfall catchment fence design. In contrast to the results from the 3x3 and 3x6 foot cylinders, in three of the four models (Section I-I' models 2a and 2b, Section A-A' model 2a) less than 5% of the 5xlO foot cylinders reach the top of the ISFSI cutslope. In the remaining model (Section A-A' model 2b), 37% of the 5xlO foot cylinders reach the top of the ISFSI cutslope. In the section A-A' model 26 analysis, 37% of the 1,000 randomly generated 10-foot long blocks reached the fence with 90th percentile of the impact energy of 294 f-tons. This energy is close to 13 times the energy delivered by the more realistic block of 3x3 foot cylinder and about 4 times the kinetic energy delivered by the conservative block of 3x6 foot cylinder.

In the three remaining analytical cases for the oversized hypothetical cylinder, less than 5% of the 1,000 randomly generated rocks reached the fence. Section I-I model 2a resulted in 5% of the simulated rocks reaching the fence with the 90th percentile kinetic energy of 172 ft-ton. This impact kinetic energy is less then the 294 ft-ton discussed above. The next analytical case involved analysis of Section I-I model 2b. In this analytical case, only 0.6% of the 1,000 randomly generated rocks reached the fence with 90th percentile kinefic energy of 437 ft-tons. Due to the limited number of cylinders reaching the fence (6 out WLA DCPP 1223-092 RockFall All 13 April 30, 2003

of 1000), the statistics analysis on 6 samples could potentially be strongly influenced by one or two sample results. In view of the very small percentage (0.6%) of hypothetical cylinder that reach the fence, we conclude that the results from this analytical case should not dictate the design. If we normalize the statistical runs to include all the oversize hypothetical cylinders that reach the fence from all four analysis cases, then the nornalized 90th percentile energy would be reduced and the effects of the "stand out" model -I' 26 runs would be reduced. The last case for the hypothetical 10-foot long cylindrical blocks analysis involves Section A-A with rocks initiating from El. 383. The results show none of the 10-foot cylindrical blocks would reach the fence in this analytical case.

Based on the CRSP analysis, the following conclusions are made:

1. For a realistic block size that can be reasonably expected at DCPP ISFSI site, it was modeled as 3-ft-dia and 3-ft-long cylindrical block in CRSP. The analysis showed that nearly 100% of the 1,000 randomly generated blocks would reach the fence with the 90'b percentile kinetic deliver at the fence of 22 ft-tons.

2. For a more conservative block size modeled as 3-fR-dia and 6-ft-long cylindrical block in CRSP, the analysis showed that nearly 100% of the 1,000 randomly generated blocks would also reach the fence with the 9Oth percentile kinetic energy deliver at the fence of 84 ft-tons.

3. To adopt a defense-in-depth approach for the rock barrier design, a hypothetical oversize block was modeled in CRSP as 5-ft-dia and 10-ft long cylindrical blocks. The analysis showed that the percent of blocks reaching the fence is significantly reduced with this increase in block size. In three of the four analysis cases, the analysis shows less than 5% of the blocks would reach the fence. Although the trend of reducing percentage of blocks reaching the fence for this size block is consistent and important, however, performing statistical analysis on the kinetic energy for the individual analysis cases which has very few blocks reaching the fence could be mis-leading.

The fourth analytical case using the large hypothetical block showed 37% of the 1,000 randomly generated blocks would.reach the fence. Statistic analysis for the 370 or so blocks would be meaningful and the 90th percentile kinetic energy delivered at the fence is 294 ft-tons. According, the kinetic energy of 294 fl-ton was selected for the rock fence design using a hypothetic block size that has mass close to 10 times the mass of the realistic block size that can be reasonably expected at the site.

Maximum CRSP-predicted bounce heights were taken at the 75 th percentile distribution, and are below 6.5 feet, with exception for the invalid 15.3 foot bounce height predicted for Model 2b.

6.0 DESIGN CRITERIA The following ISFSI cutslope design features provide mitigation against possible rockfall. Together, these mitigative features provide a redundant, multiple line of defense against the already low rockfall hazard. The hillslope above the ISFSI cutslope is inclined between about 15 and 21 degrees, and rockfall rarely occurs during earthquakes on slopes less than about 40 degrees (Keefer, 1984; Califomia Division of Mines and Geology, 1997). Additionally, our RocFall modeling and past slope performance show that even if rockfall is triggered, rockfall is unlikely to travel more than several tens of feet downhill before becoming arrested on the slope or the existing tower access road. Our detailed geologic and rock mass characterization of the site indicates that likely rockfall block sizes would be between 1 and 3 feet in maximum dimension, with a rare maximum size of 6 feet (GEO.DCPP.01.21). Such blocks would likely be angular with a rectangular or triangular cross sectional shape, and with maximum equivalent mass sphere diameters on the order of about 3 to 5 feet. Based on our rockfall modeling, a rockfall catchment WLA DCPP 1223-092 RockFall All 14 April 30, 2003

fence with a design capacity of 295 foot-tons should provide a substantial safety margin for the ISFSI against even low-probability extreme rockfall events. Additionally, modeling, past slope performance, and literature review show that a fence with a height of about 8- to 10-feet should provide a substantial freeboard for rockfall blocks that likely would roll along the slope surface rather than bounding.

The following elements comprise the rockfall mitigation system for the ISFSI.

The existing 10- to 12-foot wide tower access road provides an effective catchment bench for possible rockfall released above the roads. The road bench will be maintained and periodically cleared to maintain its effectiveness as a rockfall catchment bench.

A 2- to 6-foot-wide, 1-foot-deep drainage ditch will be constructed at the top of the cutslope (see design drawings in Attachment A; Hagler, 2003). This ditch would help catch small rockfall blocks generated on the slope above the cutslope.

An 8- to 10- oot high 295 foot-ton capacity rockfall barrier fence will be constructed at the top of the ISFSI cutslope that will be designed to absorb and dissipate energy from possible rockfall generated on the slope above. The design criteria and supporting basis for the rockfall barrier fence are described below.

The rockfall barrier fence to be constructed at the top of the ISFSI cutslope will be a commercially-available, rockfall fence system specifically designed for the possible site loading conditions. These types of rockfall barriers consist of a high-capacity, flexible cable net connected with frictional breaking systems and steel support posts. The cable is fixed to the slope with grouted rock anchors or concrete footings. As discussed in Section 5.3, the maximum bounce height of 6.5 feet, and maximum impact load of 294 foot-tons, are believed to provide a high margin of safety for the ISFSI against even unlikely extreme events. Commercial standard rockfall protection fences are available in heights of between about 9 and 15 feet, and capacities exceeding 294 foot-tons.

An example rockfall fence system under consideration is the GeoBrugg rockfall fence system that has been installed at numerous locations throughout the United States, and locally along Highway I by Caltrans. A brochure describing the GeoBrugg fence system, and several relevant case studies, are included in Attachments E and F, respectively. The final barrier design will be based on a rockfall calculation. On the basis of our computer rockfall analyses, a reasonable rockfall fence for ISFSI installation is the GeoBrugg Very High Impact fence (design load of 295 foot-tons), with a height of 8 to 10 feet. Such a system could easily withstand all foreseeable forces associated with realistic likely maximum rockfall blocks likely to be generated on the hillslope. The GeoBrugg fence is a complete system with components designed to act together to provide the 295 foot-ton capacity. These components are designed specifically to site conditions (e.g. post capacity spacing).

7.0 CONCLUSION

S The rockfall evaluation for the ISFSI hillside shows that rockfall is unlikely to reach the top of the ISFSI cutslope. RocFall computer modeling shows that small random loose rocks on the slope, and possible blocks that could fall from the overthrust toes of rock mass movements over clay beds, would only roll several to about 20 feet downhill before becoming arrested on the slope or access road benches. This conclusion matches past performance of the slope and previous rockfall evaluations for slopes of similar inclination presented in the literature (e.g., Keefer, 1994).

On this basis, we conclude that rockfall mitigation is not necessary for the ISFSI. However, considering the importance of this facility, a rockfall mitigation system is included in the ISFSI design to provide a WLA DCPP 1223-092 RockFall All is April 30, 2003

high level of safety against low probability extreme events. A multiple line of defense approach was used that includes a high-energy rockfall catchment fence at the top of the ISFSI cutslope. The capacity of the rockfall catchment fence was determined by forcing rockfalls to reach the fence location by simulation using the overly-conservative CRSP program. The resulting calculated impact forces recommended for design from the maximum rock block impacts is 295 foot-tons. This energy is within the range of the GeoBrugg High Capacity rockfall catchment fence. A fence height of 8- to 10-feet would provide a high margin of safety for likely extreme event bounce heights of rocks.

The actual blocks would be angular and exhibit lower velocities, bounce heights, energy, and probabilities for reaching the catchment fence location. The cylinder model therefore is very conservative.

(2) - Model C12b-10 runs are believed unlikely and extremely low probability, and therefore are not recommended for design input.

- 75th and 90th percentile values are calculated for the rocks that reach the fence location.

Photo 1. Overview of ISFSI slope site during exploration work. Note the steep spoil piles from exploration trenches and the lack of rockfall from the spoil piles.

Photo 2. Overview of ISFSI slope during a later stage of site exploration than shown in Photo 1. Note the switchbacking access track for drilling that extends high up the slope. Note also the lack of evidence for rolling rock from the track spoil windrows, or trench backfilling operations.

Photo 3. Typical close to moderately-spaced jointing of in situ rock mass from exploration trench T-1O in ISFSI pad area.

Photo 4. Typical close to moderately spaced jointing in rock mass in trench excavation, and slope surface roughness ranging from 6 inches to 1 foot. Note discontinuous outcrops and partial vegetation on slope.

Photo 5. Typical upper-bound slope roughness of 1 to 2 feet formed by rock talus and small outcrops in the foreground. Note the rock talus and intermixed soil and vegetation between rock blocks and outcrops that would serve to "soften" the impact from potential rockfall.

Photo 6. Typical rock block size of 6 inches to 2 feet in maximum dimension in spoil pile from Trench T-3. Note the angular and flattended aspect of the rock blocks.

Photo 7. Rocks excavated from Trench T-13 showing typical block size of 6 inches to 2 feet in maximum dimension. The trench spoils were placed on one of the steepest slope areas above the ISFSI, and the rocks stayed on the slope without rolling, even after being dumped from the excavator bucket.

Photo 8. Rocks excavated from Trench T-19 in the vicinity of slope failure model toe la location. Ipical block sizes are between 6 inches and 2 feet in maximum dimension.

As discussed on Photo 7, the spoil pile for Trench T-19 was placed on a step slope area without shedding rolling rocks.
