The site is located north of Weld County Road 24/Highway 119 and east of Weld County Road 9.75. It encompasses eight parcels totaling approximately 352 acres. This Amendment specifically includes approximately 40 acres in the southeast corner of Weld County Road 11.25 and Weld County Road 26. Site Preparation: Initial disturbance of the property will include: clearing the site of existing structures (with exception of the structures to remain), constructing the slurry wall, dewatering the site, and stripping the topsoil and overburden material. Mining: After the slurry wall installation, dewatering trenches will be excavated down to bedrock to dewater the portion of the site located within the slurry wall. Groundwater collected in the dewatering trench will be pumped into a settling pond and ultimately discharged to Tri-Town Drainage located on the east end of the property that drains to the Saint Vrain River. Once water levels are controlled through the dewatering system, scrapers will strip the topsoil and overburden material from a given phase and stockpile them separately 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 dry-mined using scrapers, bulldozers,front-end loaders, excavators, or similar equipment. The mining on this site will progress in two phases, ranging in size from 21-22 acres and proceeding from east to the west. 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 Bestway Concrete&Aggregates—The Shores-Burch Property—MLRB 112 Permit Application Exhibit D-1 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. (b) Earthmoving; Topsoil and overburden will be stripped with scrapers or bulldozers and stockpiled in segregated piles at the edge of the active mine phase. 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 phases will be mined at a 3H:1V 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. Excluding the processing area, the maximum area to be worked on at any one time is approximately 30 acres. (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 700,000 tons of aggregate per year, however, production rate may vary based on market demands. Timetable for Mining and Reclamation Phase 1: Mining will begin in Phase 1 and continue directly into Phase 2. Phase 1 will be mined in approximately 5 years and reclaimed in 1 year. Phase 2: Phase 2 will be mined in approximately 5 years and reclaimed in 1 year. 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. Bestway Concrete&Aggregates—The Shores-Burch Property—MLRB 112 Permit Application Exhibit D-2 (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 Exploratory borings drilled by Northern Colorado Geotech (NCG, 2007) primarily along the perimeter of the site, encountered approximately four to ten feet of overburden topsoil, silty sands and sandy lean clays overlying approximately 23 top 28 feet of sand and gravel on top of primarily claystone bedrock. Refer to Figure 2 of the Stability Analysis (Exhibit S) for locations of the property extents and boring locations. The bedrock depths in the proposed mine areas ranged from approximately 22 feet to 27 feet below the ground surface. (Bedrock contours are shown in Figure 3 of Exhibit S). (ii.) 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. (0 Specify if explosives will be used in conjunction with the mining(or reclamation) No explosive material will be used on-site. Bestway Concrete&Aggregates—The Shores-Burch Property—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 of earthmoving; The mined area will be reclaimed to a lined water storage reservoir due to a need within the state for water storage facilities. Refer to Exhibit F for the acreages and additional details. Earthmovinq 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 proceeds. Finish grading, topsoil placement and seeding will occur throughout the life of the mine. Once the resource is completely removed, final grading and vegetation of the slopes will be completed. The empty vessel will be available for water storage. 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. 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 3.1. The Operator will carry reclamation to completion with reasonable diligence. Each phase of 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 Bestway Concrete&Aggregates—The Shores-Burch Property—MLRB 112 Permit Application Exhibit E-1 operator at the time of excavation, silt fence and haybale dams will be installed to prevent erosion. Backfilling and grading will be completed as soon as feasible after the mining process is complete for each phase. 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. Reclaimed slopes in the water storage reservoir will not be steeper than a 3:1 ratio. The upland area 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 mine the site in phases and use concurrent reclamation methods to minimize the impact on wildlife. As described in the Savage and Savage site assessment, Exhibit H of this application, the proposed reclamation plan may improve wildlife habitat. The proposed seed mix and Bestway Concrete &Aggregates-The Shores-Burch Property—MLRB 112 Permit Application Exhibit E-2 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 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 rehandled 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 Revegetation: 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, final grading of the reservoir above the high water line will replace material at a maximum 3:1 slope to meet the grade at the top of the banks. Topsoil will be uniformly placed and spread on areas disturbed by the mining, above the anticipated high water line. 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. Bestway Concrete&Aggregates-The Shores-Burch Property—MLRB 112 Permit Application Exhibit E-3 In those areas where revegetation ispart of the reclamation plan, the Operator will 9 p 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. 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 for each phase. 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. ii. A description of the size and location of each area to be reclaimed during each phase. Please refer to the Reclamation Plan Map (Exhibit F). Outlining the sequence in which each stage or phase of reclamation will be carried out. Please refer to the Timetable for Mining and Reclamation in Section (e) of Exhibit D. (f) A description of- t Final grading-maximum anticipated slope gradient or expected ranges thereof; The finished slopes of the reservoirs will be 3 horizontal to 1 vertical. ii. Seeding-types,mixtures, quantities and time of application; Please refer to the Reclamation Plan Map for the list of plant materials and seeds to be utilized. The operator will seed during the appropriate season to ensure adequate moisture for germination and implement weed controls to allow the grasses to successfully establish.

The Saint Vrain River is approximately 2,500 feet to the north. Please refer to Exhibit C for locations of water courses in close proximity to the site, including wells, springs, stock water ponds, reservoirs and ditches. We have requested updated information from the State Engineer's Office. (b) Identify all known aquifers The Site is underlain by the St. Vrain 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 5000 feet of 4-foot wide de-watering trench, located inside of the slurry wall. The total area of exposed water is 0.5 acres. The gross annual evaporation at the the Shores aggregate mine is 42 inches according to NOM 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 Longmont where the average annual precipitation is 15.08. 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 10.56 inches. When subtracting the effective precipitation from the gross evaporation yields, the net annual evaporation is 32.13 inches, or 2.68 acre-feet per acre. The annual amount of evaporation from open water surfaces is 1.34 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).

Box 25486 DFC (MS 65412) 134 Union Denver, Colorado 80225 RE: Bestway Concrete&Aggregate,Burch Project Site, Concurrence Request that No Preble's Meadow Jumping Mouse Habitat is Present at the Burch Site Mr. Hansen: On June 8, 2013 Savage and Savage conducted a site investigation at the proposed Bestway Burch Project site in order to determine if habitat for the Preble's Meadow Jumping Mouse is present. The proposed development site is slated for mineral extraction. The Burch project site consists of approximately 32 acres contained within Section 1, Township 2 North, Range 68 West of the 6th Prime Meridian, Weld County, Colorado. The properties are bounded on the north by Weld County Road 26, on the east by a fence line, the south by the existing Bestway mineral extraction operations, and on the west by Weld County Road 11.25. Currently,the proposed Burch project site has ongoing land uses including hayfields,grazing, and an oil and gas wellhead. (Burch Property Location Map) (Burch Property Aerial Photo) The Burch site is situated on the primary alluvial terrace of St. Vrain Creek, located 0.35 miles north of the project site. The property is generally flat and slope gently to the north toward the creek. The Last Chance Ditch is located toward the north boundary of the site, flowing from west to east; and the Rural Ditch bisects the majority of the site into east and west parcels, flowing from south to north. There are no native vegetation communities extant on the parcels. There are no shrub or tree layers within the project site. The east and west parcels are hayfields dominated by alfalfa. The hayfields were being cut during our site investigation. Pasture is located north of the Last Chance Ditch. Our firm's evaluation of the site for potential Preble's Meadow Jumping Mouse habitat concluded that the site does not contain potential habitat for the mouse for the following reasons. Waterways at the site include two steep sided excavated irrigation canals with little to no potential for access by small mammals to the waterway and adjacent bank area. There is no tree or shrub component. The ditch channels and bank tops are maintained through mowing, herbicide application and brush clearing. We request that the U.S. Fish and Wildlife Service concur with our conclusion that trapping for Preble's is not necessary at this specific location, based on the habitat discussed above. If you have any questions concerning our concurrence request for the proposed Bestway Burch mineral extraction site please contact us.

Project: Wildlife Assessment for the Burch Project site Phone: 970-674-8080 Fax: 970-674-8088 Date: July 29, 2013 Attached is the wildlife assessment for the Bestway Concrete and Aggregate Burch Project site. Wildlife Assess nevi t—Bestway Concrete and Aggregate, Burch Project Introduction Savage and Savage conducted a wildlife assessment for the Bestway Burch project site on June 8, 2013. Weather during the site investigation was clear and dry, breezy with temperatures in the upper 60's (°F). An assessment of the Burch site was originally conducted in 2008. Environmental conditions at the site are unchanged from the first assessment. Site Description The Burch project site consists of approximately 32 acres contained within Section 1, Township 2 North,Range 68 West of the 6th Prime Meridian, Weld County,Colorado. The properties are bounded on the north by Weld County Road 26,on the east by a fence line,the south by the existing Bestway mineral extraction operations, and on the west by Weld County Road 11.25. Currently,the proposed Burch project site has ongoing land uses including hayfields, grazing,and an oil and gas wellhead. (Burch Property Location Map) Topography and Geomorphic Features The Burch site is situated on the primary alluvial terrace of St. Vrain Creek, located 0.35 miles north of the project site. The property is generally flat and slope gently to the north toward the creek. The Last Chance Ditch is located toward the north boundary of the site,flowing from west to east; and the Rural Ditch bisects the east and west parcels, flowing from south to north. Vegetation There are no native vegetation communities extant on the site. Both parcels contain vegetation that can be categorized as mesic-xeric introduced herbaceous communities. There are no shrub or tree layers within the project site. The east and west parcels are hayfields dominated by alfalfa(Medicago sativa). The hayfields were being cut during our site investigation. The pasture north of the Last Chance Ditch includes orchardgrass (Dactylis glomerata), pigweed (Amaranthus retroflexus), smooth brome (Bromus inermis),bluegrass (Poa spp.), with inclusions of reed canarygrass (Phalaris arundinacea), lambsquarters (Chenopodium album), and scattered curly dock(Rumex crispus). Vegetation along the banks of the Last Chance Ditch includes prairie cordgrass (Spartina pectinata) and reed canarygrass with blue green algae on the bottom of the ditch. The vegetated banks of the Rural Ditch include reed canarygrass,prairie cordgrass,wild licorice (Glycyrrhiza lepidota), and Canada thistle (Cirsium arvense)with blue green algae in the waterway. Rural Ditch vegetation behind the banks includes smooth brome, prickly lettuce (Lactuca serriola),and annual sunflower (Helianthus annuus). A locust tree(Robinia pseudoacacia)was identified midway along the Rural Ditch and a green ash tree (Fraxinus pensylvanica)was identified at the south end of the ditch. Significant Wildlife Resources Tables 1,2, and 3 list wildlife species that potentially occur on-site according to the Colorado Distribution Latilong Studies(CDOW, 1981, 1990, 1998). The latilong studies address vertebrates in the categories of mammals, birds,reptiles, and amphibians. Significant Wildlife Habitat The lack of consistent vegetative,topographic, or geomorphic cover within the project site limits significant wildlife use for nesting, loafing, hunting, or as a corridor. When the alfalfa fields are growing, these plants provide forage for herbivores and subsequent hunting opportunities for predators. The channels and banks of the Last Chance and Rural Ditches provide foraging and corridor wildlife habitat to a minor degree,though use is restricted by steep incised banks and a lack of tree and shrub cover. These areas receive some wildlife use by raccoons, muskrats, and waterfowl as evidenced by the tracks observed,however they do not provide significant wildlife habitat. Seasonal Use of Potentially Occurring Wildlife Species With the exception of bats (identified from the list of potentially occurring species),the mammal species encountered during the site inspection or that potentially occur on-site are expected to be year-round residents or users of the site. The carnivore and ungulate species are not restricted to this site and tend to have relatively large home ranges (up to several square miles). The majority of rodent and insectivore species can be expected to reside on-site throughout the year,though many may hibernate during the cold months. Avian species may be year-round,temporary migrants, or summer residents of the site. Year-round residents would include waterfowl,raptors, gallinaceous birds, doves,owls, and woodpeckers. The majority of the shorebirds and passerines would use the site during the spring, summer, and fall for breeding, feeding or resting during migration. Amphibian and reptile species of the site are year-round residents. Species of Special Concern The U.S.Fish and Wildlife Service lists animal and plant species as threatened or endangered in the State of Colorado. Of those listed species, the U.S. Fish and Wildlife Service has expressed an interest in three that may potentially be present in the project site or adjacent areas, the bald eagle(Haliaeetus leucocephalus),the Preble's meadow jumping mouse(Zapus hudsonius preblei),and the Ute ladies'-tresses orchid(Spiranthes diluvialis). Bald Eagles Bald eagles (Haliaeetus leucocephalus)reside from mid-November through the end of July along the St. Vrain Creek corridor and in scattered tree copses on the plains. There are no mature nesting trees on the proposed development site, however there are potential scattered nesting trees along the St. Vrain Creek corridor and at nearby homesteads. These areas were investigated and no bald eagle nests or bald eagles were encountered. In an interview with Chris Mettenbrink of the Colorado Division of Wildlife on March 20,2008 he confirmed that there are no active bald eagle nests near the proposed project site. In a recent interview with Chris Mettenbrink of Colorado Parks and Wildlife on June 9,2013,Mr. Mettenbrink confirmed that there are still no active bald eagle nests in the area of the project site. Mining activities proposed by Bestway are therefore not likely to adversely affect bald eagles. Preble's Meadow Jumping Mouse Surveys or site disqualifications for the Preble's Meadow Jumping Mouse (Zapus hudsonius preblei)are required for eligible Colorado sites below 7400 feet elevation in Boulder, Douglas, El Paso, and Jefferson Counties (Colorado),the South Platte River 100 year floodplain, tributaries, and associated wet meadow complexes (from the Front Range to Ft. Morgan, Colorado) in Adams, Arapahoe,Denver, Elbert, Larimer, Morgan, and Weld counties. The U.S. Fish and Wildlife Service has described the characteristic habitat of the mouse as areas with the following features; low undergrowth with grasses and forbs, in open wet meadows and riparian corridors or where tall shrubs and low trees provide cover. The mouse prefers mesic to hydric lowlands, and has been found in agricultural and native landscapes, along irrigation canals, and natural drainages,as well as areas dominated by both introduced and native plant species. The Service is also requiring surveys in areas with seeps, native hayfields, stream channels, and floodplains. A telephone interview was conducted with Adam Misztal of the U.S. Fish and Wildlife Service(USFWS)on March 20, 2008. He said there have been several negative trapping surveys along St.Vrain Creek east of U.S. Interstate 25 and that this area is not considered to be mouse habitat. On June 8, 2013 Savage and Savage conducted an investigation in order to determine if habitat for the Preble's Meadow Jumping Mouse is present at the Burch site. Waterways at the site include two steep sided incised irrigation canals. There is no tree or shrub understory. The ditch channels and bank tops are maintained through mowing,herbicide application and brush clearing. Our firm concluded that the site does not contain potential habitat for the mouse. Savage and Savage received concurrence from the U.S. Fish and Wildlife Service on July 11, 2013 that no Preble's meadow jumping mouse habitat is located at the Burch site. Ute Ladies'-Tresses Orchid The Ute Ladies'-Tresses orchid (Spiranthes diluvialis) is a federally listed, threatened plant species known to occur in Colorado. Interim U.S. Fish and Wildlife Service survey requirements(USFWS, 1992) for the orchid require surveys along the South Platte River 100-year floodplain and perennial tributaries and in potentially critical orchid habitat. Characteristic orchid habitat requiring a survey includes sites below 6500 feet elevation with seasonally high water tables, wet meadows, stream channels, floodplains, wetlands, and areas where vegetation falls into the facultative wet or obligate classification. Sites excluded from the survey requirement include upland sites (short grass prairie and sagebrush rangeland) and highly disturbed or modified sites. Sites not requiring a survey for the orchid include sites entirely composed of dense stands of reed canarygrass and dense stands of other specific types of vegetation. The banks of both the Last Chance and Rural Ditches are composed of dense stands of reed canarygrass. A Ute Ladies'-Tresses Orchid survey is not required for the banks of the ditches. The remainder of the site is hayfield and pasture with predominantly upland vegetation that is not considered habitat for the orchid. Project Effects to Wildlife Noise and air emissions during mining will cause a temporary disturbance to wildlife during active operations. Some wildlife species will be temporarily displaced with mining operations within the pit area. Species such as raccoons, coyotes,beaver,deer, and raptors will continue to use the property and adjacent areas during mining operations and the site itself when operations are not active. Bird species will use the periphery of the site and the site itself opportunistically, if prey or food species are present. The proposed project will extract material and leave open water and areas of uplands within the project site. Permanent reclamation of the site will entail grading,respreading topsoil, and seeding and planting perennial native species that will support wildlife species. The mining and reclamation will create a more diverse habitat than is currently present. Areas of open water will sustain species of reptiles and amphibians as well as shorebirds and waterfowl. With the planting of additional native trees and shrubs, additional strata and vegetation layers will be added to the site, creating improved cover, foraging,roosting,and nesting areas for wildlife. With replacement of desirable graminoid, forb, shrub, and tree species during the project, mining and reclamation will result in enhancement of wildlife habitat on site.

This property is in a semi-arid continental climate strongly influenced by the Rocky Mountains. The area is usually warm in the summer with frequent hot days. In winter, periods of very cold weather are caused by arctic air moving in from the north or northwest. Milder periods occur when westerly winds are warmed as they move down slope off of the mountains to the west. Weather monitoring data is not available from the site. The nearest weather monitoring station is the Longmont 2 ESE, Colorado, Station 055116 in the National Weather Service (NWS) cooperative network. The table below lists the average minimum and maximum temperature, and average total precipitation on a monthly and annual basis for the period of record from August 1, 1948 to November 30, 2004. Most of the precipitation occurs as rainfall during the warmer part of the year with the heaviest rainfalls in the late spring and early summer. Winter snowfall is frequent but the snowcover usually melts quickly during the milder periods.

Mining will be complete for this phase with mining occurring at the final shoreline reclamation slope (3H:1V). This phase will require final grading, topsoil placement, seed and mulch. • Phase 2 would be 100% mined and 100% reclaimed. This phase will be mined at the final shoreline reclamation slope (3H:1V). This phase will require final grading, topsoil placement, seed and mulch. • The processing area used for this property will be at the main Shores Pit, therefore there will be no reclamation of a processing area for the Burch Property. • The slurry wall is proposed to be installed prior to exposure of groundwater. Therefore we request the option for 20% bonding of this cost. The slurry wall design, specifications, and quality assurance plan will be approved through a technical revision process prior to exposure of groundwater in the pit. Groundwater may be exposed as necessary for construction of the slurry wall in accordance with the approved substitute water supply plan (SWSP).

Bestway Concrete&Aggregates—The Shores-Burch Property—MLRB 112 Permit Amendment Application Exhibit S-1 January 2, 2014 Mr. Mark Johnson, Compliance Manager Bestway Concrete&Aggregates 301 Centennial Drive Milliken, Colorado 80543 Re: Stability Analysis for the Burch Amendment to the Shores Gravel Mine(M-1998-013) Dear Mr.Johnson: 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(6.4.19, Exhibit S)for the proposed Burch Property Amendment for the Shores Aggregate 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 approximately one-half mile south of St.Vrain Creek. The site is within the east half of the northwest%, Section 1, Township 2 North, Range 68 West of the 6th Principal Meridian: The site is generally bounded on the west by Weld County Road (WCR) 11.25,the north by WCR 26, on the east by an agricultural field, and on the south by a single family residence and an existing gravel mine. The project is located in Weld County, Colorado,as shown on Figure 1. Approximately five feet of overburden is underlain by a relatively deep alluvial aggregate deposit. The aggregate will likely be transported via conveyor to a processing plant located at the southwestern portion of the active mine area. Bestway Concrete&Aggregates plans to construct a slurry wall around the entire mining area on the Burch Property at a 3:1 (horizontal to vertical)slope,as indicated in the DMG 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,extent of economically mineable aggregate or other issues. GEOLOGY 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 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(Qp). 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. , Mr. Mark Johnson January 2,2014 Page 2 GEOTECHNICAL CONDITIONS The mine site is located on a terrace of St Vrain Creek. The Piney Creek Alluvium most likely overlies sandstone and claystone bedrock of the Denver Formation. Exploratory borings drilled by Northern Colorado Geotech (NCG, 2003)primarily along the southern boundary of the site, encountered three to seven feet of overburden topsoil and silty clayey sand overlying sand and gravel ranging in depth from 17 feet to the maximum depth drilled of 20 feet. Weathered siltstone/claystone was encountered in one boring at 17 feet in depth below the existing ground surface. 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 NCG geotechnical exploration completed by Terracon in September 1997. 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: • Last Chance Ditch relocation (western, northern,and eastern boundaries) • WCR 11.25(western boundary) • Stinar of Longmont, residence, sheds, barn, dairy milking parlor, metal grain bin, and fences(western boundary) • Vogl Trustees of Longmont,residence and utility shed(northwestern boundary) • Overhead power line(northern boundary) • WCR 26 (northern boundary) • Kerr-McGee Burch 3-1A well(northeast corner of site) • Rural Ditch Return relocation(eastern boundary) • Rural Ditch Return—Phase I (eastern half of site) • Kerr-McGee oil road (southern boundary) • Rural Ditch Return relocation (southern boundary) • Kerr-McGee gas line(southern boundary) • Lee of Longmont(Globoker Owner), residence, sheds, dairy milking parlor, grain bin (southwest boundary) STABILITY ANALYSES The stability of the proposed mining limits was evaluated at six 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. Mr. Mark Johnson January 2 , 2014 Page 3 Therefore, prior to submitting the final stability run, at least 288 failure surfaces were analyzed to determine the lowest factor of safety. The six cross-section locations were selected to analyze proposed setbacks for stability of structures using appropriate surcharge loads for the mining limits. Cross sections A, B, C, E,and F are modeled with a 3:1 (RN) highwall and include a slurry wall. Cross sections A, B, and C are modeled to include the relocation of the Last Chance Ditch. Section C is also modeled to include the relocation of the Rural Ditch Return. Cross section D is modeled with a 3:1 highwall but without a slurry wall. Cross section D was modeled to represent the Rural Ditch Return in its existing location and also for when the Rural Ditch Return will be relocated to the eastern side of the project site. All mining slopes are modeled to be no steeper than 3:1 (H:V). Phase 3 was modeled to include a soil-bentonite slurry wall(Sections B and E). The locations are described below and shown on Figure 1. ► Section A-A': This section considers the closest distance to the farm structures,WCR 11.25,and the relocated Last Chance Ditch. A high phreatic surface was included to model the maximum water surface from the ditch, a surcharge of 250 psf was included to model the live load of the road and a surcharge of 2000 psf was included to model the dead load from the building. ► Section B-B': This section considers WCR 26, the overhead power line, and the relocated Last Chance Ditch. A high phreatic surface was included to model the maximum water surface from the ditch; a surcharge of 250 psf was included to model the live load from the road, and a surcharge of 100 psf was included to model the dead load from the power line. ► Section C-C': This section considers The Rural Ditch and relocation of the Rural Ditch Return along the eastern margin of the site: A high phreatic surface was included to model the maximum water surface from the ditches. ► Section D-D': This section considers the Kerr-McGee Burch 3-1A well located between phase 1 and phase 2. A surcharge of 500 psf was included to model the live load from the access road and dead loads from the well and associated tanks. ► Section E-E': This section considers Kerr McGee's gas line, access road,and the relocation of the Rural Ditch Return to the south boundary of the site. A high phreatic surface was included to model the maximum water surface from the ditch. ► Section F-F': This section considers Kerr McGee's gas line, access road, and the relocation of the Rural Ditch Return to the south boundary of the site. A high phreatic surface was included to model the maximum water surface from the ditch. A surcharge of 300 psf was included to model the live load from the access road and dead load from the gas line. The material index and engineering strengths assumed in this slope stability report are discussed below. Mr. Mark Johnson January 2 ,2014 Page 4 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 Moist Unit Saturated Unit Cohesion C' Friction Angle 0:1)'° Weight(pct) Weight(pcf) Weight(pct) psf 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 Moist Unit Saturated Unit Cohesion C'psf Friction Angle V° Weight(pcf) Weight(pct) Weight(pci) 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 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 five-foot thick layer overlying the peak strength bedrock as follows: Dry Unit Moist Unit Saturated Unit Weight Weight Oct) Weight(pct) Cohesion C'psf Friction Angle�'° c Peak= 135 116 Peak= 126 Residual= Peak= 100 Peak=25 Residual = 110 133 Residual =0 Residual= 15 Mr. Mark Johnson January 2 , 2014 Page 5 Soil-Bentonite Slurry The proposed slurry wall will consist of a mix of the overburden clay 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 clay overburden. Based on engineering judgment, we modeled the slurry wall as follows. Dry Unit Moist Unit Saturated Weight(pct) Weight(pct) i Untr Weight Friction Angle 0 Cohesion C'psf c NA 112 115 0 0 STABILITY ANALYSES RESULTS Stability analysis included three conditions: 1. Proposed dry mining slopes with a slurry wall. 2. Seismic loads from an estimated earthquake load with a mine full of water. 3. Rapid draw down of water levels within the mine. 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 likely be increased more for construction and maintenance than for stability. Mr. Mark Johnson January 2 ,2014 Page 6 LIMITATIONS Our review is based on regional geologic mapping,present mining plans, borehole data from Northern Colorado Geotech, 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 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. Please call with any questions or comments.
