The site is located north of the Cache La Poudre River, east of WCR 13 and south of Highway 392. It encompasses 19.7 acres +/-. Site Preparation: Initial disturbance of the property will include: clearing the site of existing structures (with exception of the structures to remain), dewatering the site, and stripping the topsoil and overburden material. Mining:, Dewatering trenches will be excavated down to bedrock to dewater the portion of the site being mined. Groundwater collected in the dewatering trench will be pumped into a settling pond and ultimately discharged to the Poudre River located on the south end of the property. Once water levels are controlled through the dewatering system, scrapers will strip the topsoil and overburden material and stockpile them for use during site reclamation. Any excess material not needed for reclamation may be sold or hauled off -site during the life of the mine. The sand and gravel material will be excavated down to bedrock. Each phase will be wet -mined using scrapers, bulldozers, front-end loaders, excavators, or similar equipment. The operator will develop and comply with a Stormwater Management Plan and Spill, Prevention, Control and Countermeasures Plan. The operator will notify the Division of Mine Safety and Reclamation in the event of a reportable spill. Processing: All material mined under this proposed application will be transported by conveyor or haul truck to the processing area. Import Material: Bestway Concrete & Aggregates may import material from and export material to other sites. The applicant is aware that in accordance with Rule 3.1.5(9) of the Construction Material Rules and Regulations, if any offsite material is used as backfill, a notarized letter will be submitted to the Division indicating the materials are inert. The applicant will supply such a letter to the Division if, at the time of Reclamation, the applicant intends to use off -site material as backfill. Bestway Concrete & Aggregates — Lee Amendment -N. La Poudre Mine — MLRB 112 Permit Application Exhibit D -1 (b) Earthmoving; Topsoil and overburden will be stripped with scrapers or bulldozers and stockpiled in segregated piles at the edge of the active mine. Excavators, front-end loaders, and bulldozers will be used to excavate the material. Conveyor belts or haul trucks will be utilized to transport the raw material from the active mine phase to the processing area. The site will be mined at a 1H:1V V slope. (c) All water diversions and impoundments; and The perimeter of the mined area will be dewatered by digging a trench to bedrock. The water will be pumped into a settling pond and discharged in accordance with a CDPS permit. Wash water for the processing area will be recycled through a series of small ponds within the processing area. The water required to operate the facility will likely be provided by the existing water rights associated with the property. No ditches will be disturbed without prior authorization of the appropriate ditch company. (d) The size of area(s) to be worked at any one time. The entire 19.7 acres will be worked at one time. (e) An approximate timetable to describe the mining operation. The timetable is for the purpose of establishing the relationship between mining and reclamation during the different phases of a mining operation. The Operator anticipates that mining will commence as soon as all permits are in place. The Operator anticipates extracting approximately 500,000 tons of aggregate per year, however, production rate may vary based on market demands. Timetable for Mining and Reclamation Mining will begin as one phase and take approximately one to two years. Reclamation will take another year to complete. Reclamation will begin immediately after mining is complete. When possible, concurrent reclamation practices will be used to minimize site disturbance and to limit material handling to the greatest extent possible. Please refer to the Mining Plan Map in Exhibit C for phase areas to be mined, locations and areas. (0 Use Mining Plan Map in conjunction with narrative to present: (i.) Nature, depth and thickness of the deposit and thickness and type of overburden to be removed Bestway Concrete & Aggregates — Lee Amendment -N. La Poudre Mine — MLRB 112 Permit Application Exhibit D - 2 Exploratory borings were performed by Bestway Concert and subcontracted to Drilling Engineers. The bedrock depths in the proposed mine areas ranged from approximately 15 feet to 19 feet below the ground surface. Nature of the stratum immediately beneath the material to be mined in sedimentary deposits The site is located approximately 15 miles east of the foothills of the Colorado Front Range on the western flank of the Denver Structural Basin. The basin is a downwarp of sedimentary strata that tends north-northwest, parallel to the mountain front. In the project area, the sedimentary bed dips gently eastward toward the axis of the basin east of the site. Based on regional geologic mapping (Colton, 1978), the near surface bedrock in the project area is the Paleocene and Upper Cretaceous Denver and Arapahoe Formations. The bedrock is overlain by upper Pleistocene and Holocene (Quarternary age) gravel deposits and eolian (wind blown) overburden soils. The gravel deposits exist primarily within the Broadway Alluvium deposit. The bedrock unit consists mainly of claystone and may contain lenses of siltstone and sandstone. (g) Identify the primary and secondary commodities to be mined/extracted and describe the intended use. The primary commodities are sand, gravel and fill; intended for construction materials. (h) Name and describe the intended use of all expected incidental products to be mined/extracted by the proposed operation. There are no expected incidental products to be mined. (i) Specify if explosives will be used in conjunction with the mining (or reclamation) No explosive material will be used on -site. Bestway Concrete & Aggregates — Lee Amendment -N. La Poudre Mine — MLRB 112 Permit Application Exhibit D - 3 EXHIBIT E - RECLAMATION PLAN This information provided in this Exhibit is intended to satisfy the requirements outlined in Section 6.4.5 of the Colorado Mined Land Reclamation Board Construction Material Rules and Regulations: The proposed mining and reclamation plan focuses on minimizing the ecological impacts of mining, minimizing the length of time of impact, and maximizing long-term benefits. (a) A description of the type(s) of reclamation the Operator proposes to achieve in the reclamation of the affected land, why each was chosen, the amount of acreage accorded to each, and a general discussion of methods of reclamation as related to the mechanics ofearthmoving; The mined area will be reclaimed to existing grade. Refer to Exhibit F for the acreages and additional details. Earlhmoving The topsoil will be replaced by a scraper and generally graded with a blade. All grading will be done in a manner that controls erosion and siltation of the affected lands, to protect areas outside the affected land from slides and other damage. In addition, all backfilling and grading will be completed as soon as feasible after the mining process. All disturbed areas will be regraded and smoothed to a finished grade that is suitable for revegetation or the final land use. As noted previously, the area will be reclaimed as mining commences. Finish grading, topsoil placement and seeding will occur once the resource is completely removed. A typical cross-section of the shoreline is included on the Reclamation Plan Map. (b) A comparison of the proposed post -mining land use to other land uses in the vicinity and to adopted state and local land use plans and programs. Once returned to existing (pre -mined) grade, the site can return to being farmed. The water storage reservoirs will be compatible with the other land uses in the vicinity, which includes farmland, industrial land, and rural residential. (c) A description of how the Reclamation Plan will be implemented to meet each applicable requirement of Section 3.7. The Operator will carry reclamation to completion with reasonable diligence. Reclamation will be completed within one to two years from completion of mining, but not more than five years from the date the Operator informs the Board or Office that such phase has commenced. Section 3.1.5 Reclamation Measures Material Handling. Grading will be performed to help control erosion and siltation of the affected lands through phased mining, implementing good operation techniques to handle material as little as possible, and vegetation of stockpiles remaining in place for more than one growing season. Although the use of erosion protection devices is not anticipated, if deemed necessary by the operator at the time of excavation, silt fence and haybale dams will be installed to prevent Bestway Concrete & Aggregates — Lee Amendment -N, La Poudre Mine — MLRB 112 Permit Application Exhibit E -1 erosion. Backfilling and grading will be completed as soon as feasible after the mining process is complete. Maximum slopes and slope combinations will be compatible with the configuration of surrounding conditions and selected land use. Mining will occur at a slope that is stable. The site will be reclaimed to grades consistent with pre -mining elevations. The operator will backfill using fill material generated on -site, or imported inert fill generated outside the permit area. If any inert off -site material is used as backfill, a notarized letter will be submitted to the Division as required by Section 3.1.5(9) of the MLRB Construction Material Rules and Regulations. It is not anticipated that mining will uncover any refuse or acid-forming or toxic producing materials, however if any such materials are encountered the operator will take precaution to handle the materials in a manner that will control unsightliness and protect the drainage system. Drill or auger holes that are part of the mining operation shall be plugged with non- combustible material, which shall prevent harmful or polluting drainage. Any test pits, soils boring holes, or monitoring wells not located within the mine excavation limits will be plugged as soon as it can be confirmed that they are no longer needed for the operation. Mined material to be disposed of within the affected area will be handled in such a manner so as to prevent any unauthorized release of pollutants to the surface drainage system. No unauthorized release of pollutants to groundwater shall occur from any materials mined, handled or disposed of within the permit area. Section 3.1.6 Water -General Requirements The Operator will comply with applicable Colorado water laws governing injury to existing water rights and with applicable state and federal water quality and dredge and fill laws and regulations. The operator will develop and comply with a stormwater management plan and will use best management practices (BMPs) to ensure groundwater and surface water are protected to the greatest possible extent. BMPs include schedules of activities, prohibitions of practices, maintenance procedures and other management practices to prevent or reduce the pollution in runoff from the site. Section 3.1.7 Groundwater - Specific Requirements The Operator will comply with the applicable standards and conditions for classified and unclassified groundwater. Section 3.1.8 Wildlife: The mining and reclamation plans have been designed to account for the safety and protection of wildlife on the mine site. The Operator will use concurrent reclamation methods to minimize the impact on wildlife. The proposed reclamation plan may improve wildlife habitat. The proposed seed mix and plantings will create improved cover, foraging, roosting, and nesting areas for wildlife. The water area within the reservoir will serve as habitat for waterfowl and other bird species and the fringes of the reservoir will be used by mammal, bird, reptile and amphibian species. Control and/or removal of Bestway Concrete & Aggregates — Lee Amendment -N. La Poudre Mine — MLRB 112 Permit Application Exhibit E - 2 noxious and weedy species during the project and the replacement of desirable graminoid, forb, shrub and tree species during reclamation will result in enhancement of wildlife habitat on the project site. Section 3.1.9 Topsoiling. Topsoil shall be removed and segregated from other spoil. Topsoil stockpiles shall be stored in places and configurations to minimize erosion and located in areas where disturbance by ongoing mining operations will be minimized. Once stockpiled, topsoil shall be rehandied as little as possible. Stockpiles that will remain in place for more than one growing season will receive vegetative cover, as outlined on the Reclamation Plan Map, as soon as possible to minimize erosion. Section 3.1.10 Revegetatiorr. In those areas where revegetation is part of the reclamation plan, the land shall be revegetated in a manner that establishes a diverse, effective, and long-lasting vegetative cover that is capable of self -regeneration without continued dependence on irrigation or fertilizer and is at least equal in extent of cover to the natural vegetation of the surrounding area. The proposed seed -mix and plantings for reclamation are outlined on the Reclamation Plan included in Exhibit F of this application. Section 3.1.11 Buildings and Structures Please refer to the enclosed Reclamation Plan included in Exhibit F. Section 3.1.12 Signs and Markers The Operator will post appropriate signage at the entrance to the mine site. The permit area will be marked by existing fencing, or proximity to existing County roads. (d) Plans for topsoil segregation, preservation and replacement; for stabilization, compaction and grading of spoil; and for revegetation_ Topsoil will be removed and segregated from other spoil. Topsoil not needed for reclamation may be sold or removed from the site. For reclamation, topsoil will be replaced by a scraper and generally graded with a blade. Grading shall be done in a manner that controls erosion and siltation of the affected land and protects areas outside the affected land from slides and other damage. In addition, backfilling and grading shall be completed as soon as feasible after the mining process. Final grading will create a final topography that is appropriate for the final land use. For example, grades on the site will be returned to existing (pre -mining) grade. Topsoil will be uniformly placed and spread on areas disturbed by the mining. The minimum thickness shall be 6 inches above the surrounding finished grade, consistent with existing topsoil depths on -site. The topsoil shall be keyed to the underlying and surrounding material by the use of harrows, rollers or other equipment suitable for the purpose. In those areas where revegetation is part of the reclamation plan, the Operator will revegetate the land in such a manner so as to establish a diverse, effective, and long- lasting vegetative cover that is capable of self -regeneration without continued dependence on irrigation or fertilizer and is at least equal in extent of cover to the natural vegetation of the surrounding area. Seed will be drilled and mulched. Bestway Concrete & Aggregates — Lee Amendment -N. La Poudre Mine — MLRB 112 Permit Application Exhibit E - 3 The revegetation seeding and plant list on the Reclamation Plan Map contains the preferred species of grasses, shrubs and trees to be planted. Seeding will take place once final grading and replacement of topsoil have been completed. Timing of seeding will be consistent with standard horticultural practice for dryland applications - generally between late September and the middle of April to ensure there is adequate moisture for germination. (e) A plan or schedule indicating how and when reclamation will be implemented. Include: i. An estimate of the periods of time which will be required for the various stages or phases of reclamation. Please refer to the Timetable for Mining and Reclamation in Section (e) of Exhibit D. ill A description of the size and location of each area to be reclaimed during each phase.

The Cache La Poudre River is approximately 1,200 feet to the south. Please refer to Exhibit C for locations of water courses in close proximity to the site, including wells, springs, stack water ponds, reservoirs and ditches. (b) Identify all known aquifers The Site is underlain by the Cache La Poudre River alluvial aquifer. (c) Show how water from dewatering operations or runoff from disturbed areas, piled material and operating surfaces will be managed to protect against pollution of either surface or groundwater both during and after the operation. Please refer to the Mining Plan Map in Exhibit C of this application. Mine areas will drain internally. Uncontrolled releases of surface water in disturbed areas will not occur. Stormwater collected in the active mine area will be managed through the dewatering system. (d) Estimate project water requirements including flow rates and annual volumes for the development, mining and reclamation phases of the project. Projected Use And Consumption: Annual evaporative depletions will be the evaporation from up to 4000 feet of 4 -foot wide de -watering trench. The total area of exposed water is 0.5 acres. The gross annual evaporation at the gravel mine is 38.5 inches according to NOAA Technical Report NWS 33, Evaporation Atlas for the Contiguous 48 United States. Monthly evaporative losses are determined using percentages specified by the State Engineer's Office for locations below 6,300 feet. The nearest weather station is in Windsor where the average annual precipitation is 13.97. Effective precipitation, that part of historical precipitation which was consumed by native vegetation on land to be covered by water surface, is conservatively estimated to be 70 percent of the total precipitation. The annual average effective precipitation at the property is estimated to be 9.78 inches. When subtracting the effective precipitation from the gross evaporation yields, the net annual evaporation is 28.72 inches, or 2.39 acre-feet per acre. The annual amount of evaporation from open water surfaces is 1.20 acre-feet. Mining Production & Operations: Bestway Concrete & Aggregates expects to extract a maximum of 500,000 tons annually of aggregate material from the site. The water retained in the 500,000 tons will be replaced pursuant to the Substitute Water Supply Plan (SWSP). The total annual amount of water retained in the gravel product from mining activities totals 14.71 acre-feet. Bestway Concrete & Aggregates — Lee Amendment -N. La Poudre Mine — MLRB 112 Permit Application Exhibit G -1 In addition, an estimated 1.93 acre-feet of water per year will be used for dust control based (approximately) on 3,500 gallons per day for 20 days per month for 9 months. Annually the total evaporative and operational losses from mining activities (open water surface evaporation, water retained in the aggregate product, dust suppression) totals 17.98 acre-feet of depletion which must be augmented. All depletions were lagged to the Poudre River using the lagging factors approved by the State Engineer pursuant to on -going Substitute Water Supply (SWSP) approvals. (e) Indicate the projected amounts of the water sources to supply project water requirements Replacement Water: The source of replacement water for depletions will be long term lease between Bestway Concrete & Aggregates and Central Colorado Water Conservancy District. The State Engineer must approve a SWSP every year. These approvals require that the applicant provide a detailed explanation of the mining operations, a quantification of all mining activities and subsequent depletions and all legally available replacement sources. (0 Affirmatively state that the Applicant has acquired or applied for a National Pollutant Discharge Elimination System permit from the Water Quality Control Division The Operator will apply for a National Pollutant Discharge Elimination System (NPDES) permit from the Water Quality Control Division of the Colorado Department of Public Health and Environment prior to discharging water from the site.

The map unit descriptions in this report, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. USDA Natural Resources Web Soil Survey i Conservation Service National Cooperative Soil Survey 11/9/2016 Page 1 of 22 Map Unit Description--Larimer County Area, Colorado; and Weld County, Colorado, Southern Part Soils that have profiles that are almost alike make up a soil series. All the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of a given series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha -Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. Additional information about the map units described in this report is available in other soil reports, which give properties of the soils and the limitations, capabilities, and potentials for many uses. Also, the narratives that accompany the soil reports define some of the properties included in the map unit descriptions.

La Poudre Mine — MLRB 112 Permit Amendment Application Exhibit S -1 March 17, 2017 Mr. Mark Johnson, Compliance Manager Bestway Concrete & Aggregates 301 Centennial Drive Milliken, Colorado 80543 Re: Stability Analysis for the Lee Amendment — N. La Poudre Gravel Mine (M -2000-144) Dear Mr. Johnson This letter has been prepared to address the Mined Land Reclamation Board (NLRB) Construction Materials Rule 6, Section 4, Subsection 19, Exhibit S - Permanent Man -Made Structures (6.4.19, Exhibit S) for the proposed Lee Property Amendment for the N. La Poudre Gravel Mine. This letter describes the project and slope stability calculations carried out to evaluate the minimum distance between the edge of mining and adjacent structures to avoid damage to the structure. The site is located north of the Cache La Poudre River, east of WCR 13 and south of Highway 392. The site is within the northwest Y4 of Section 19, Township 6 North, Range 67 West of the 61h Principal Meridian. The project is located in Weld County, Colorado, as shown on Figure 1. Bestway Concrete & Aggregates plans to wet mine the entire mining area on the Lee Amendment Property with a mining slope of 1:1 (horizontal to vertical), as indicated in the DRMS permit application. This report lists proposed safe setbacks for mining from structures within 200 feet of the permitted mining boundary based on stability calculations. 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 twenty (15) miles east of the foothills of the Colorado Front Range on the western flank of the Denver Structural Basin. The basin is a down warp of sedimentary strata that trends north-northwest, parallel to the mountain front. Based on regional geologic mapping (Colton, 1978), the near surface material in the project area is the Piney Creek Alluvium (Op). The Piney Creek Alluvium consists of dark -yellowish brown or grayish -orange, clayey to fine sand, and well -stratified silt. The bedrock unit consists mainly of claystone and may contain lenses of siltstone and sandstone. GEOTECHNICAL CONDITIONS The mine site is located on a terrace of the Cache La Poudre River. The Piney Creek Alluvium most likely overlies sandstone and claystone bedrock of the Denver Formation. Well construction data obtained for the area encountered approximately four feet of overburden topsoil overlying sand and gravel ranging in depth from 16 feet to 19 feet. As a conservative approach based on experience and information gathered from existing mines in the area, it was assumed that the top four feet of bedrock is weathered claystone overlying non -weathered claystone. Mr. Mark Johnson March 17, 2017 Page 2 From a geotechnical standpoint, the sand and gravel will form the majority of the mine slopes. These soils are generally strong and stable, particularly when dewatered. SITE GROUNDWATER Civil Resources conservatively modeled the groundwater at five feet below the ground surface, based on the geotechnical exploration completed by Drilling Engineers in 2017 and data from Bestway Concrete. 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 Bestway Concrete & Aggregates are listed below: • WCR 131 N. County Road 1 (Weld County Public Works)(Larimer County Public Works) • Highway 392 / WCR 68 (Weld County Public Works) • Traffic Light (Intersection)(Weld County Public Works) • Overhead Power Line (Western & Eastern Boundary)(PVREA) • Drainage Easements (CDOT/Windsor) • Gas Line (Southern Boundary)(DCP) • Gas Line (Western & Northern Boundary)(XCEL Energy) • Gas Facility (XCEL) • Telephone (West & North)(Century Link) • Pond (West of site)(United Water & Sanitation District) • Cable (West & North)(Comcast Link) • Cable (West & North)(Dark Corn) • Water Line (Western & Northern Boundary)(Town of Windsor) STABILITY ANALYSES The stability of the proposed mining limits was evaluated at four sections under anticipated loading conditions around the perimeter of the site and is 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 12 termination points and 12 initiation points (144 failure circles) with 7 foot line segments over a broad range of the slope surface. This procedure is repeated over different initiation and termination locations until the most critical factor of safety failure surface is identified. The range is narrowed and 12 initiation points and 12 termination points (144 failure circles) with 7 foot line segments for the final run of 144 circles to determine the lowest factor of safety. Therefore, prior to submitting the final stability run, at least 288 failure surfaces were analyzed to determine the lowest factor of safety. The four cross-section locations were selected to analyze proposed minimum setbacks for stability of structures using appropriate surcharge loads for the mining limits. The cross sections are modeled with a 1:1 (H:V) highwall. All mining slopes are modeled to be no steeper than 1:1 (H:V). The locations are described below and shown on Figure 1. Mr. Mark Johnson March 17, 2017 Page 3 ► Section A -A': This section considers WCR 13 / N. County Road 1, and Xcel Energy's gas line and facility 100' west of the mine highwall. A high phreatic surface was included to model the maximum water surface. A surcharge of 400 psf was included to model the live load of the road. ► Section B -B': This section considers WCR 131 N. County Road 1 and utilities. A high phreatic surface was included to model the maximum water surface. A surcharge of 400 psf was included to model the live load of the road. ► Section C -C': This section considers Highway 392 / WCR 68 and utilities. A high phreatic surface was included to model the maximum water surface. A surcharge of 400 psf was included to model the live load of the road. ► Section D -D': This section considers the overhead power line along the eastern boundary of the site. A high phreatic surface was included to model the maximum water surface. A surcharge of 200 psf was included to model the live load from the access road and dead load from the overhead power line. The material index and engineering strengths assumed in this slope stability report are discussed below, MATERIAL PROPERTIES Overburden The index properties for the insitu clay 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 (pct] Moist Unit Weight c Saturated Unit _ Weight (pcf) Cohesion C' psf Friction Angle 4~' ° 103 114 126 50 29 Alluvial Sand and Gravel The sand and gravel is generally medium -grained sand, medium dense, poorly to well graded, and generally clean. The deposit ranges from fine to coarse sand with some silt and occasional rounded to well rounded gravels less than two inches in diameter. The alluvial sand and gravel has been modeled as follows: Dry Unit Weight (pct) Moist Unit Weight (0) Saturated Unit Weight (pci) Cohesion C' psf Friction Angle 0' ° 119 129 130 0 35 Claystone Bedrock The proposed mine area is generally underlain by claystone bedrock. Claystone is generally a weak bedrock and is often prone to slope instability and the bedrock foundation strength is critical for the highwall stability. 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, 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 Mr. Mark Johnson March 17, 2017 Page 4 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 jobs and engineering judgment, the residual strength claystone was modeled in a four -foot thick layer (conservative) overlying the peak strength bedrock as follows: Dry Unit Weight (pct) Moist Unit Weight (PO Saturated Unit Weight (pcf) Cohesion C psi Friction Angle' ° 116 Peak = 126 Residual = 110 Peak = 135 Residual = 133 Peak =100 Residual = 0 Peak = 25 Residual =15 STABILITY ANALYSES RESULTS Stability analysis included one conditions: 1. Proposed dry mining slopes (dewatered). Setbacks listed in Table 1 indicate the minimal setback from the structure to the mining limits. The setback distance can be increased as needed to address other restrictions. The factor of safety shown below is the minimum factor of safety of the three conditions listed above.

CONCLUSIONS The minimum distances proposed in this report will protect the subject structures, however, the actual setbacks may be increased for constructability and maintenance considerations. LIMITATIONS Our review is based on regional geologic mapping, present mining plans, public well construction data, and stability analyses 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 effects 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.

La Poudre Mine — MLRB 112 Permit Amendment Application March 17, 2017 Mr. Mark Johnson Bestway Concrete & Aggregates 301 Centennial Drive Milliken, Co 80543 RE: North La Poudre Gravel Mine -Lee Amendment - Mitigation Plan for Potential Groundwater Impacts Dear Mr. Johnson: The purpose of this letter is to describe the existing groundwater regime in the vicinity of the proposed North La Poudre Gravel Mine (Site) and the groundwater impacts that could result from the additional Lee Property being amended to the existing gravel mine, Existing Groundwater Conditions The prevailing groundwater flow direction at the in the vicinity of the Site area is south-southeast toward the Cache La Poudre River. Mining of the area and has been ongoing since the 1980's or earlier. Locally the groundwater levels and flow directions are influenced by: ➢ Existing Mines and Properties: The surrounding properties are; • Town of Windsor's lined reservoir to the northwest, • CN LLC unlined water pond to the north, • Hayden's Property containing an unlined water pond to the north and, • the Weakland Property to the northeast, which contains a farm building and dryland. • United Water and Sanitation's clay lined Seder Pond to the west, • an active gravel mine to the east owned by Bestway Concrete and, • Central Colorado Water Conservancy District's slurry lined pond to the southeast. ➢ Surface Water: Approximately 1000 -feet to the south of the Site is the Cache La Poudre River. Potential Mining impacts to Local Groundwater Levels The proposed mining will directly west of the North La Poudre Mine as shown on the Groundwater Map Figure. Currently dewatering activates have been ongoing in the North La Poudre and La Poudre Gravel mines with no negative impacts. A brief summary of the properties surrding the proposed amended site are presented below, • CN LLC: The current house is approximately 2,000 feet north of the proposed gravel mining area. The domestic and irrigation wells (Permit #14529-f & 14941-F) are north of the onsite pond, approximately 200 feet away from the proposed mining area. The existing pond acts as a buffer form dewatering activities and is a significant distance away from the proposed gravel mining area. Page 2 Mr. Mark Johnson March 17, 2017 Hayden Property: The current house is approximately 2000 feet north of the proposed gravel mining area. The domestic and irrigation wells (Permit # 628 & 15990 -R -R) are north of the onsite pond, approximately 200 feet away from the proposed mining area. The existing pond acts as a buffer form dewatering activities and is a significant distance away from the proposed gravel mining area. The Weakland Property: is approximately 2000 feet northeast of the proposed site. There are two wells onsite, one is a deep well approximately 550 feet deep and the other is 50 feet (Permits #247465 & 247465-A). The wells are a significant distance away from mining and is buffered from the dewatering area by the North La Poudre Pit. 9 Windsor Reservoir & Serfer Reservoir: The Windsor Reservoir and Serfer Reservoir are both lined and will be unaffected during mining. Dewatering: The North La Poudre Mine which has been dewatered to bedrock in 2013 and 2014 with no negative impacts to the surrounding well owners. The approximate dewatering rate was 350 gallons per minute which will remain the same during dewatering of the Lee Amendment. Below is a brief description of the calculation used to determine the drawdown due to mining; The radial well equation was used to determine the drawdown surrounding the mine. fe -r_ 3 ln(r1 ! rW) Using a well pumping rate of 380 gallons per minute (50 acre-feet per month) and an effective sump radius (area used to pull the water down and set the trash pump in) of 250 feet the drawdown at 1,600 feet is zero (existing water levels are met, 13 feet above bedrock or 7 feet below grade). Therefore a dewatering rate of 380 gallons per minute will have very little drawdown effect on the surrounding well users. Onsite Monitoring•. There are three wells that will be continuously monitored as shown in the attached figure. Currently the water levels are as follows during recent observation. Monitoring Well East is 4.5 feet below grade and Monitoring Well West is 7.5 feet below grade Mitigation Measures Proposed activities on the Site have very limited potential to result in significant off -site groundwater impacts to the local groundwater levels and therefore mitigation should not be required but in the event the operator has to mitigate they have the ability to drill wells deeper, truck in water or provide irrigation water should it be needed. Conclusion The potential for reduction in groundwater in the surrounding properties that will affect the well is limited. The applicant will continue to monitor the groundwater levels in the wells.
