19 Thiel Engineering PO Box 1010, Oregon House, CA / fax 530/ Memo To: File From: Richard Thiel CC: Date: June 25, 2002 Re: Weyco HQ Cell 3 Site Exploration Conducted preliminary exploration of Cell 3 subgrade and embankment soils today. Work consisted of: Excavating 8 test pits (TP1 through 8) within Cell 3 footprint east of Cell 2, and TP9 in future Cell 4 which is anticipated futher east. Field map of approx. test pit locations is attached. Excavated 6 test pits on top of the Big Stockpile just south of the leachate pond. The purpose of the test pits was to qualitatively evaluate the soils in the stockpile as possible embankment materials for Cell 3, which at this time is anticipated to require approx. 70,000+ cubic yards of embankment. The findings and preliminary conclusions from this field investigation are described below. The work occurred June 25, 2002 from 7:00 a.m. till 4:00 p.m. with a 1 hr break for lunch. Cell 3 Test Pits The 8 test pits within the future Cell 3 were excavated in a southnorth alignment along the approximate middle of the future cell, starting at the approximate south boundary about 150 north of the 1600 road. The equipment used was a CAT 235 excavator operated by Ron Haskins. I was accompanied almost the whole time by Larry Fulcher, and for a few of the test pits by Chris Haynes, both of Weyerhaeuser. Test pits 1 and 2 showed generally soft materials for as deep as the excavator could go (20 for TP1 and 25 for TP2; TP1 was shallower because of geometric constraints with topography, and not because of refusal). The top 45 was moist, fairly mediumstiff lowplasticity clay, brown to browngray in color with Page 1

20 reddishbrown mottling and very few rocks. The next several feet was a fat, gray, wet, mediumstiff clay with no sand or gravel. TP1 then had a few feet of a yellow highplasticity silt, and then both TP1 and 2 had a highplasticity (MH) gray silt. The consistency of these MH materials was soft to medium, and they were wet. The bottoms of both test pits ended in wet, multicolored silty materials containing hard pieces of weathered rock (hard to tell if was weather lithic tuff or weathered basalt). Based on experience in other test pits, this transition indicates that hard basalt would not be much further down. TP3 appeared to be a linear transition from what was experienced in TP s 1 and 2 vs. TP4. It was excavated in an area formerly stripped for its wetlands soils. The top 2 feet was a moist, stiff, brown CL which quickly transitioned to a yellow altered tuff, wet, medium stiff, MH material. This transitioned to a similar material but yellowgray in color that was a bit softer. At about 10 deep weathered basalt was hit, with refusal at 12. TP4 had 23 of moist, stiff, brown CL and then immediate refusal. The remainder of TP5 through 8 were similar with 48 of moist, stiff, brown CL material underlain by weathered basalt that quickly presented refusal to the excavator. TP9 was excavated to the east of future Cell 3 in an area of stripped wetlands. It was excavated because it had obvious saturated fat gray clay exposed right at the ground surface. This clay extended unchanged for a depth of 8 feet. From 8 14 feet a wet, friable, weathered rock material was encountered that was very stiff to hard in the vertical direction, but easily crumbled by hand when excavated. Refusal was met at 14. Preliminary Implications for Cell 3 Design Essentially all of Cell 3 will be filled by an average of about 7 of fill. The soft soils on the south side of the cell do not pose a constructability problem, but may cause total and differential settlements, and the softness of some of the materials may be cause for concern relative to slope stability. These issues should be evaluated. Thiel Engineering intends to perform preliminary evaluations of these issues making simplifying assumptions regarding the distribution, compressibility, and shear strength of these materials based on the field observations. If the preliminary evaluations present a potential for concern, further field investigation using a drill rig to obtain relatively undisturbed samples may be warranted. Big Stockpile Test Pits BS1 through 5 were excavated today on the big stockpile for two reasons. One was to look for potential cover soils for the Cell 1 closure. The second was to qualitatively evaluate the potential use of these soils for embankment to make the Page 2

21 Cell 3 subgrade. The following general observations apply to all the test pits except for BS4. The top 23 feet generally contained damp material near the optimum moisture content that had a healthy stand of grass that had developed over several years (510). The material was generally a silty or clayey loam with rocks. Below this two types of materials were encountered in general: (1) a wet, stiff, black, lean clay containing roots and organics, and (2) wet brown sandy clay with many 6 minus basalt rocks of medium consistency. All of these materials appeared to be embankable, but the lower two would require drying. The stiff black clay would be the more difficult to dry. I collected samples of the lower two materials to run laboratory tests for inplace water content, Proctor curve, and Atterberg limits. This information may be useful for the Cell 3 bid documents. BS4 was excavated on what appeared to be the scraper haul road up the stockpile. It appeared to contain the driest and most rocky material. It would make very good embankment, but terrible topsoil. Implications for Cell 3 Design Based on the test pits it appears that there would be adequate quantity and quality of embankment material for Cell 3, but it would require some work to dry the material close to optimum moisture content. Some of the clay may be more difficult to dry and work, but it is feasible in the judgment of Thiel Engineering and also of Ron Haskins who is a very experience construction foreman who has worked on this site for the past 10 years for TriState.

22 TEST PIT LOGS Weyco HQ Landfill Cell 4 Test pits excavated afternoon of Dec. 18, 2006 starting approximately 350 east of NE corner of Cell 3 (TP10), then moved to location about 130 south of proposed NE corner of Cell 4 (TP11); then an additional 250 south along the proposed eastern limit (TP13). These three test pits were in the deeper sections of proposed cut areas. TP12 and TP14 were adjacent to the existing 1600A road in fill areas. TP15 and TP16 were in deeper fill areas in the SE area of the proposed footprint where wetlands soils had been borrowed. The excavation was performed by site operator (Kevin) using CAT Excavator 320. Test pits logged by Richard Thiel, PE. No samples were taken.
