Civil Resources. LLC 323 5th Street Frederick. CO 80530 Re: Vogl Gravel Mine Traffic Study Letter WCR-26 and WCR-13 Weld County, Colorado Dear Mr. Rodriguez: The purpose of this letter report is to document the results of a traffic analysis prepared for the proposed Vogl Gravel Mine to be located along the north side of Weld County Road 26 (WCR-26) and WCR-24.75 between WCR-9.75 and WCR 13 in Weld County. Colorado. It is expected that the project will be completed within approximately one year; therefore, analysis was conducted for the 2020 buildout year. This traffic study identifies project traffic generation characteristics. potential project traffic related impacts on the local street system. and mitigation measures required for identified impacts of the study area key intersection of WCR-26 and WCR-13. The primary work hours for the mine are anticipated to be between 6:00 AM and 6:00 PM Monday through Friday with a 10 -hour shift occurring on Saturdays. Existing Site and Roadway Network Regional access to the Vogl Gravel Mine will be provided by Interstate 25 (I-25). WCR-13 and State Highway 66 (SH-66). Primary and direct access to the site will be provided by WCR-26 and WCR- 24.75. The project location is shown in an attached aerial exhibit and vicinity map of Figure 1. The existing site consists of vacant land with agricultural uses and one single family residence. The surrounding area primarily consists of ranch style residences, single family communities. agricultural land. and vacant land. The site area is shown in attached Figure 2. WCR-13 provides one lane of travel northbound and southbound with a double yellow centerline and a posted speed limit of 45 miles per hour. WCR-26 extends east -west with one through lane in each direction with a double yellow centerline east of the project limits. WCR-26 and WCR-24.75 are both unpaved roadways adjacent to the project site. The intersection of WCR-26 and WCR-13 currently operates with stop control along the eastbound and westbound WCR-26 approaches. All four approaches of this intersection include a single shared lane for all movements. The existing lane configurations and control for this intersection are shown in attached Figure 3. Existing Traffic Volumes Existing peak hour turning movement counts were conducted at the key intersection of WCR-26 and WCR-13 on Wednesday, October 2; 2019. Existing turning movement count sheets are attached. The counts were conducted in 15 -minute intervals during the morning and afternoon peak hours of adjacent street traffic from 7:00 AM to 9:00 AM and 4:00 PM to 6:00 PM. The turning movement counts for this intersection are also shown in attached Figure 3. Unspecified Development Traffic Growth Traffic projections from the Weld County 2035 Transportation Plan (attached) were utilized to estimate traffic volumes for the project buildout year of the project in 2020. From this transportation 4582 South Ulster Street, Suite 1500, Denver; CO 80237 303 228 2300 Kimley >>> Horn Traffic Study Letter 096548005 Page 2 plan. WCR-13 is anticipated to experience an annual growth of approximately 3.48 percent within the project limits. Based on this. a growth rate of 3.50 percent was used to estimate future 2020 background traffic volumes at the study area key intersection. Background traffic volumes for year 2020 are shown in attached Figure 4. Trip Generation Site -generated traffic estimates are determined through a process known as trip generation. The number of employees anticipated as well as the number of truck trips in and out daily and per hour were estimated for the proposed gravel mining operations. The gravel mine is anticipated to have five (5) employees. Therefore. it is anticipated that five (5) employees will be assigned to the site. For purposes of this study, it was assumed that all five employees would arrive and depart in a common peak hour in a drive -alone fashion resulting in five vehicles entering the gravel mine in the morning peak hour and five vehicles exiting the mine during the afternoon peak hour. Although employees are expected to remain on -site, daily trips were doubled in the scenario in case of leaving for a break to provide a conservative daily trip analysis. As mentioned previously, the primary work hours for the mine are anticipated to be between 6:00 AM and 6:00 PM Monday through Friday (12 -hour days) with a 10 -hour shift occurring on Saturdays. It was estimated that a maximum of 50 trucks (100 trips in and out) will access the gravel mine each day, which equates to slightly more than four (4) trucks per hour assuming a 12 -hour work day. Some hours will see four trucks come in and leave while others will have five. For purposes of this study, the peak hour volume of five trucks in and out was assumed (5 trucks in and 5 trucks out in the AM and PM peak hours). Table 1 provides the trip generation estimate for the Vogl Gravel Mine. Based on the estimates. the gravel pit is anticipated to generate a total of 120 trips daily. Of these, 15 trips are anticipated to occur during both the morning and afternoon peak hours.

Anticipated hauling routes were also obtained from the client. The directional distribution of traffic is a means to quantify the percentage of site - generated traffic that approaches the site from a given direction and departs the site back to the original source. Attached Figure 5 illustrates the expected project trip distribution for the Vogl Gravel Mine. Traffic assignment was obtained by applying the project trip distribution to the estimated traffic generation of the project shown above in Table 1. Traffic assignment for the project is shown in attached Figure 6. Project traffic volumes were added to the background volumes to represent estimated traffic conditions for year 2020. These 2020 background plus project (total) traffic volumes are shown in attached Figure 7 for the key intersection. kimley- orn.com 4582 South Ulster Street, Suite 1500, Denver, CO 80237 303 228 2300 Kimley *Horn Traffic Study Letter 096548005 Page 3 Traffic Operations Analysis Kimley-Horns analysis of traffic operations was conducted to determine if the addition of the Vogl Gravel Mine project traffic can be accommodated to maintain acceptable operations of the existing WCR-26 and WCR-13 intersection without the need for improvements. The acknowledged source for determining overall capacity is the Highway Capacity Manual. Capacity analysis results are listed in terms of Level of Service (LOS). LOS is a qualitative term describing operating conditions a driver will experience while traveling on a particular street or highway during a specific time interval. It ranges from A (very little delay) to F (long delays and congestion). Typical standard traffic engineering practice identifies overall intersection LOS D and movement LOS E as the minimum thresholds for acceptable operations. Synchro traffic analysis software was used to analyze the study area intersection. The Synchro Highway Capacity Manual (HCM 6th Edition) methodology reports were used to analyze intersection delay and level of service. Table 2 shows the definition of level of service for signalized and unsignalized intersections. Table 2 - Level of Service Definitions Level Service of Signalized Average (sec/veh) Total Intersection Delay Unsignalized Average (sec/veh) Intersection Total Delay A ≤10 I ≤10 B > 10 and≤20 > 10 and≤15 C > 20 and ≤ 35 > 15 and ≤ 25 D > 35 and ≤ 55 > 25 and ≤ 35 E > 55 and ≤ 80 > 35 and ≤ 50 F > 80 > 50 Definitions provided from the Highway Capacity Manual. Sixth Edition. Transportation Research Board. 2016. WCR-26 and WCR-13 The intersection of WCR-26 and WCR-13 currently operates with stop control along the eastbound and westbound approaches. All four approaches of this intersection include a single lane for all movements. The intersection is flat and the roadways connecting are straight, with the intersection roadways being at a perpendicular 90 -degree angle. Therefore, sight distance availability is good for the roadway characteristics. Under the unsignalized analysis, the level of service (LOS) for a two-way stop -controlled intersection is determined by the computed or measured control delay and is defined for each minor movement. Level of service for a two-way stop -controlled intersection is not defined for the intersection as a whole. With the existing conditions; all movements at this intersection currently operate acceptably with LOS B or better during the peak hours. With existing lane configurations and addition of project traffic, all movements at the WCR-26 and WCR-13 intersection are expected to continue to operate acceptably with LOS B or better during the morning and afternoon peak hours in 2020. Therefore, no modifications are anticipated to be needed at this intersection to accommodate project traffic. Table 3 provides the results of the level of service for the intersection of WCR-26 and WCR-13 (capacity analysis worksheets are attached). kim ley -horn. corn 4582 South Ulster Street, Suite 1500, Denver, CO 80237 303 228 2300 Kimley >> Horn Table 3 — WCR-26 and WCR-13 LOS Results Traffic Study Letter 096548005 Page 4 Scenario AM Peak Hour PM Peak Hour Delay (sec/veh) LOS Delay (sec/veh) LOS 2019 Existing Northbound Left 7.8 A 7.9 A Eastbound Approach 12.6 B 12.5 B Westbound Approach 13.9 B 12.7 B Southbound Left 7.9 A 7.9 A 2020 Background Northbound Left 7.8 A 7.9 A Eastbound Approach 12.8 B 12.6 B Westbound Approach 14.3 B 12.9 B Southbound Left 7.9 A 8.0 A 2020 Background Plus Project Northbound Left 7.8 A 7.9 A Eastbound Approach 13.0 B 12.6 B Westbound Approach 14.7 B 13.2 B Southbound Left 7.9 A 8.0 A Conclusion and Recommendations The Vogl Gravel Mine is anticipated to generate approximately 120 daily trips during the weekday operating hours of 6:00 AM to 6:00 PM. Of these, 15 peak hour trips are anticipated (trucks and employees) in the morning and afternoon peak hours. Based on the analysis presented in this report, Kimley-Horn and Associates. Inc. believes this Vogl Gravel Mine project traffic volume will be incorporated into the existing roadway network and will not require any traffic improvements along either WCR-26 or WCR-13 other than the installation of R1-1 "STOP" signs on the driveway approaches from the site to the adjacent public streets. Based on the results of the intersection operational analysis. the recommended lane configurations and control of the study key intersection is shown in Figure 8, which demonstrates that no changes in control or lane configurations are anticipated to be necessary.

Stability Analysis for the Vogl Amendment of the Shores Gravel Mine Dear Mr Johnson I This letter has been prepared to address the Mined Land Reclamation Board (MLRB) Construction Materials Rule 6, Section 4, Subsection 19, Exhibit S - Permanent Man -Made Structures (6 419, Exhibit S) for the proposed Vogl Amendment of the Shores Gravel Mine located in Weld County, Colorado This letter describes the project and slope stability analyses utilized to evaluate the minimum distance between the edge of mining and adjacent structures to avoid damage to the structure The site is located west and north of the intersection of Weld County Roads 11 '/ and 26, immediately north of the Town of Firestone, Colorado More specifically, the mine is within parts of Section 1, Township 2 North, Range 68 West and Section 36, Township 3 North, Range 68 West of the 6th Principal Meridian The site is 200 feet south of the Saint Vrain River at its closest point Land uses in the area include agricultural, oil and gas production, active gravel mines, gravel mines reclaimed as below grade reservoirs, and residential housing The mine plan is shown on Figure 1 The site will be mined in four cells referred to as Cell 1, Cell 2a, Cell 2b, and Cell 3 The Cells 2a and 3 will be lined with soil-bentonite slurry walls and will be reclaimed as below grade reservoirs Cells 1 and 2b will be unlined and will receive wash fines from the processing of mined sand and gravel The unlined cells (Cells 1 and 2b) will be mined at a slope of 2 horizontal to 1 vertical (2H 1V) The lined cells (Cells 2a and 3) will be mined at a slope of 3H 1V Based on the stability analyses, this report indicates that the setbacks and perimeter slopes in the mining plan are sufficient to protect structures within 200 feet of the permitted mining boundary Actual setbacks may be greater due to permit limitations, zoning requirements, construction issues, agreements with owners, and extent of economically mineable aggregate or other issues GEOLOGY The Site is located approximately 17 miles east of the eastern flank of the Rocky Mountain Front Range Younger sedimentary strata dip eastward off the Pre -Cambrian igneous and metamorphic rocks that form the core of the Front Range into the Denver Structural Basin The Denver Basin is an asymmetrical downwarp of sedimentary strata with a steeply dipping west limb and a gently dipping east limb Bedrock does not crop out at the site, however regional geologic mapping of the area (Colton, 1978) indicates the near surface bedrock at the site is most likely the Upper Transition Member of the Pierre Shale with the Fox Hills Sandstone mapped just to the east Colton (1978) describes the Upper Transition Member as friable sandstone containing sandy shale and large calcareous sandstone concretions Colton (1978) describes the Fox Hills Sandstone as cross bedded sandstone that grades downward to a fine grained silty sandstone interbedded with gray fissle shale The regional mapping indicates the bedrock is overlain by the Post Piney Creek and Piney Creek Alluviums The Piney Creek is mapped over the area of Cell 1 and parts of Cells 2a and 3 The Post Piney Creek is mapped at parts of Cells 2a and 3 and all of Cell 2b Colton (1978) describes these alluvial deposits as sandy to gravelly alluvium Mr Mark Johnson April 3, 2020 Page 2 GEOTECHNICAL CONDITIONS Based on the site investigations, the natural site stratigraphy generally consists of three main units 1) Overburden generally consisting of sandy clay and clayey and silty sands, 2) sand and gravel alluvial deposits that underlie the overburden and overlie the bedrock, and 3) bedrock usually consisting of sandy claystone with local areas of sandstone These units are described in more detail below 3 51 Overburden Unit The overburden at the site typically consists of brown sandy clay and clayey to silty sand that locally overlies a buff silty sand The surficial brown clayey to silty sand overburden unit is typically approximately 2 to 3 feet thick with the top 6 to 8 inches containing significant organics This unit is locally thinner to not present or is locally as thick as 5 feet 3 5 2 Sand & Gravel Unit The sand and gravel is present throughout the site underlying the overburden and overlying the bedrock This unit typically consists of gravelly, fine to coarse grained sand locally grading to sandy gravel This unit ranges in thickness from approximately 10 feet to 22 feet , 3 5 3 Bedrock The bedrock encountered in the exploratory borings was generally weathered in the upper one to two feet typically becoming harder in unweathered zones The bedrock consisted of sandy claystone with local sandstone The approximate top of bedrock contours are presented on Figure 1 3 5 4 Groundwater Groundwater was encountered in all of the borings at approximately 4 to 9 feet below ground surface The groundwater levels will vary seasonally and will typically rise during the irrigation season Groundwater will be controlled with the proposed below grade slurry wall to be constructed in cell 2a, 3, and Pond A After slurry wall construction, groundwater mounding is anticipated on the upgradient (west and south) side of the site and a groundwater shadow (deeper water table) is anticipated on the downgradient (north and east) side the site Cells 1 and 2b will be dewatered with perimeter dewatenng trenches excavated into the bedrock The dewatenng will extend beyond th'e perimeter of these mine cells From a geotechnical standpoint, the sand and gravel will form the majonty of the mine slopes These soils are generally strong and stable, particularly when dewatered Submittal STRUCTURES WITH 200 FEET OF DISTURBED AREAS The known, permanent, man-made structures within 200 feet of the proposed mine areas that are not owned by Burnco are listed below UTILITIES CENTRAL WELD WATER, ST VRAIN SANITATION, KERR-MCGEE OIL & GAS/ANADARKO/OXY, NOBLE ENERGY, UNITED

COMMUNITIES Mr Mark Johnson April 3, 2020 Page 3 STABILITY ANALYSES Recently, Division of Reclamation and Mining Safety (DRMS) staff drafted a policy regarding stability analyses of neighboring structures The draft summarizes adequate factors of safety (FOS) for non -critical and critical structures The structures around the Vogl Amendment and Shores Gravel mine are, for the most part, considered critical structures Discussions with the author of the memo, Mr Tim Cazier, indicate the FOS will be adopted by the Mined Land Reclamation Board (MLRB) The FOS are for both static and seismic (from an earthquake) stability analyses For generalized strength assumptions and critical structures, a FOS of 1 5 is considered sufficient for static conditions and a FOS of 1 3 is considered suitable for seismic conditions The stability of structures within 200 feet of the proposed mining limits was evaluated at nine (9) sections The sections evaluated either at the tallest high wall or in the area of the closest structure in each mine cell under anticipated loading conditions around the perimeter of the site as discussed below The computer program XSTABL was used for the analysis The method for selecting the critical failure surface for each analyzed loading condition is the following The Modified Bishop's Method of Analysis is used to find the critical failure surface by randomly searching with 20 termination points and 20 initiation points (400 failure circles) with 7 foot line segments over the slope surface and at the structure in question to determine the lowest factor of safety Both static stability under anticipated mining conditions and seismic stability under peak ground acceleration loads were performed Seismic loading was obtained from the U S G S Unified Hazard Tool Review of the Hazard Tool indicated a maximum horizontal acceleration of 0 096g with a return period of 2,475 years for the site The seven cross section locations were selected and analyzed as described below All of the sections met adequate FOS as summarized below in Table 1 The section locations are shown on Figure 1 Celli Section D This section is on the northwest side of Cell 1 and considers the tallest mine highwall of this cell where the mine highwall is closest to the Last Chance Ditch The stability analysis for this section assumes a mine highwall sloped at 2 horizontal to 1; vertical (2H 1V) The nearest structure is the Last Chance Ditch located approximately 31 feet to the northwest The stability analysis on this section was run with potential failure circles initiating at the ditch and terminating in the area near the base of the mine highwall Section F This section is on the west side of Cell 1 and considers the tallest highwall on the west side of the cell where the mine is closest to a fence The stability analysis for this section assumes a mine highwall sloped at 2 horizontal to 1 vertical (2H 1V) The nearest structure is the fence located approximately 25 feet to the west The stability analysis on this section was run with potential failure circles initiating at the fence and terminating in the area near the base of the mine highwall Section G This section is on the south side of Cell 1 and considers the case of the closest structure to the mine (the Rural Ditch) The stability analysis for this section assumes a mine highwall sloped at 2 horizontal to 1 vertical (2H 1V) The nearest structure is the Rural Ditch located approximately 17 feet to the south The stability analysis on this section was run with potential failure circles initiating at the Rural Ditch and terminating in the area near the base of the mine highwall The analyses indicated a sufficient FOS However, this FOS was the lowest of all the sections analyzed The mine limit was moved another 20 feet to the north The actual FOS will be greater than the FOS presented below (Table 1) Mr Mark Johnson April 3, 2020 Page 4 Cell 2a Section B This section is on the northeast side of Cell 2a and considers the case of the tallest highwall and the closest structure (a gravel road) The stability analysis for this section assumes the presence of a slurry wall and a mine highwall of 3H 1V The gravel road is located approximately 45 feet north of the highwall The stability analysis on this section was run with potential failure circles initiating at the gravel road and terminating in the area near the base of the mine highwall Section E This section is on the northwest side of Cell 2a and considers the case of the tallest highwall and the closest structure (a fence) on this side of the cell The stability analysis for this section assumes the presence of a slurry wall and a mine highwall of 3H 1V The fence is located approximately 47 feet west of the highwall The stability analysis on this section was run with potential failure circles initiating at the fence and terminating in the area near the base of the mine highwall ► Cell 2b Section A This section is on the northeast side of cell 2b and is the tallest highwall in the cell The stability analysis for this section assumes a mine highwall sloped at 2 horizontal to 1 vertical (2H 1V) The nearest structure is a fence located approximately 20 feet to the north The stability analysis on this section was run with potential failure circles initiating at the fence and terminating in the area near the base of the mine highwall ► Cell 3 Section C This section is on the northeast side of cell 3 where the tallest highwall is present The nearest structure is the Tn-Town Drainge District drain channel located approximately 45 feet to the east The stability analysis for this section assumes the presence of a slurry wall and a mine highwall of 3H 1V The stability analysis on this section was run with potential failure circles initiating at the drainage ditch and terminating in the area near the base of the mine highwall ► Pond A Section H This section is on the west side of Pond A in an unmined area with a previously constructed slurry wall Available borehole data indicates the depth to bedrock and corresponding highwall height would be approximately 21 or 22 feet We conservatively modeled this section with a highwall height of 30 feet The highwall is 25 feet from the slurry wall and mined at a 3H,1V slope The nearest structure is a gas line located approximately 31 feet from the mine limit The stability analysis on this section was run with potential failure circles initiating at the gas line and terminating in the area near the base of the mine highwall Section I This section is on the north side of Pond A (Shores Gravel Mine) in an unmined area with a previously constructed slurry wall Available borehole data indicates the depth to bedrock and corresponding highwall height would be approximately 21 or 22 feet We conservatively modeled this section with a highwall height of 30 feet The highwall is 25 feet from the slurry wall and mined at a 3H,1V slope The nearest structure is the Rural Ditch located approximately 74 feet from the mine limit The stability analysis on this section was run with potential failure circles initiating at the Rural Ditch and terminating in the area near the base of the mine highwall MATERIAL PROPERTIES The material index and engineering strengths assumed in this slope stability report are discussed below Mr Mark Johnson April 3, 2020 Page 5 Overburden The strength properties for the insitu sandy clay to silty to clayey sand overburden were based on field testing data and on our engineering judgment, the following parameters have been used to model the overburden Dry Unit Weight (pcf) Moist Unit Weight (pcf) Saturated Unit Weight (pct) Cohesion C' psf Friction Angle cP' Native 103 114 126 50 29 Alluvial Sand and Gravel The sand and gravel is generally a medium to coarse -grained sand that is medium dense to dense and locally gravelly The alluvial sand and gravel was modeled as follows Dry Unit Weight (pct) Moist Unit Weight (pcf) Saturated Unit Weight (pcf) Cohesion C' psf Fnction Angle 4,' 119 129 130 0 35 Bedrock Bedrock below the alluvium is predominately sandy claystone with local sandstone Sandstone is typically stronger than claystone Claystone is generally a weak bedrock To be conservative, we modeled the bedrock as claystone For the claystone bedrock, two potential strength conditions were considered These strength conditions are referred to as 1) peak strength, and 2) residual strength Peak strength is the maximum shear strength the claystone bedrock exhibits The shear strength is made up of both cohesion (diagenetic bonding) and internal friction Under short-term conditions for unsheared claystone, peak strength governs behavior If a sheared surface or sheared zone is present within claystone as a result of faulting, slippage between beds due to folding, past shrink -swell behavior, stress relief, weathering, or from a landslide, the cohesion along the sheared surface is reduced to zero, and the angle of internal friction is decreased, due to alignment of clay minerals parallel to the shear plane Under these conditions a claystone exhibits its lowest strength known as residual strength Residual strength bedrock occurs in discrete zones, parallel with the sheared surface or zone, whereas fully softened strength occurs over a broader area (not used in this modeling) Based on data from other recent projects and engineering judgment, the residual strength claystone was modeled in a one -foot thick layer overlying the peak strength bedrock as follows Dry Unit Weight (pct) Moist Unit Weight (pcf) Saturated Unit Weight (pcf) Cohesion C' psf Friction Angle P' 116 Peak =126 Residual =110 Peak =135 Residual =133 Peak =100 Residual = 0 Peak = 27 Residual = 15 Soil-Bentonite Slurry Wall The proposed slurry wall will consist of a mix of the overburden clayey to silty sand, alluvial sand, and imported bentonite The resulting mix will produce a non -Newtonian fluid with some shear strength characteristics based on a reduced friction angle of the overlying overburden Based on engineering judgment, we modeled the slurry wall as follows Mr Mark Johnson April 3, 2020 Page 6 Dry Unit Weight (pct) Moist Unit Weight (pct) Saturated Unit Weight (pcf) Cohesion C' psf Friction Angle cl)' NA 112 115 0 0 STABILITY ANALYSES RESULTS The stability analyses assumed the mining will be per the mine plan The plan includes dewatenng with a series of perimeter drains in Cells 1 and 2b and perimeter highwalls of 2 horizontal to 1 vertical Dry mining will occur in cells 2a and 3 as the water level in these cells will be controlled by slurry walls The perimeter mine slopes of cells 2a and will be no steeper than 3H 1V Setbacks listed in Table 1 (below) indicate the setback from the structure to the mining limits The setback distance can be increased as needed to address other restrictions such as weaker than anticipated soils, deeper mining, or unanticipated groundwater The factor of safety shown below in Table 1 is the minimum factor of safety of the conditions listed above TABLE 1 - SLOPE STABILITY RESULTS AND SETBACKS Cell Section

above, the mine will not be a hazard to neighboring structures provided the structure and slurry wall offsets, as well as the perimeter mine slopes, follow the mine plan LIMITATIONS Our review is based on regional geologic mapping, present mining plans, and in part borehole data by Civil Resources and others Stability analyses were performed using typical strength parameters for the various strata in the critical sections Should the mining plans change or subsurface conditions vary from those portrayed in this letter, we should be contacted in order to re-evaluate the potential affects on permanent man-made structures Stability analyses were run at the structure in question and were not run on failure surfaces closer to the highwall Note also that surcharge loads due to temporary material stockpiles and overburden berms were not considered in the analysis Mr. Mark Johnson April 3, 2020 Page 7 Please call with any questions or comments.
