Savage and Savage (2021) Exhibit J, Vegetation Information EXHIBIT J- Vegetation Information Site Description A Savage and Savage botanist and plant ecologist conducted an on -site vegetation assessment for the proposed Aggregate Industries Tucson South Conveyor project site on June 29, 2021 The project site is comprised of approximately 7200 linear feet of conveyor comdor within the east half of Section 36 of Township 1 North, Range 67 West, Weld County, Colorado, and the east half of Section 1, of Township 1 South, Range 67 West of the 6th Prime Mendian, Adams County, Colorado The center of the project site is located at 40 003140° latitude and -104 839075° longitude The property is located northwest of Brighton, Colorado between Colorado Highway 7, and Weld County Road 23 75 The project site is accessed from Tucson Street and Weld County Road 23 5 Weather during the site investigation was warm, dry, and partly overcast with a temperature in the mid -60's (°F) The topography of the site is dominated by the primary alluvial terrace of the South Platte River The elevation of the project area averages 4955 feet and slopes gently to the east toward the river The soils that dominate the site are formed from alluvium and consist of loams and clays, generally underlam by aggregate with varying groundwater levels The sigmficant hydrologic feature near the site is the South Platte River The conveyor comdor is sited alongside Tucson Street north of Colorado Highway 7 and Weld County Road 23 5 north of Colorado Highway 7 (Figure 1) The general area has been developed for aggregate resources and agriculture, with little of the native vegetation remaining These areas have no tree overstory and no shrub understory Active and inactive agricultural areas dominate the remainder of the area adjacent to the proposed conveyor comdor Three vegetation communities or types are found within the proposed Tucson South Conveyor project site dryland agriculture, pivot -irrigated agriculture, and a reclaimed herbaceous grass and forb community The vegetation communities are within three distinct locations along the proposed conveyor comdor Vegetation Communities Dryland Agriculture The dryland agriculture community is located along Weld County Road 23 5 at the north end of the proposed conveyor corridor This community extends from Weld County Road 23 75 0 26 miles south (Figure 2) At the time of the site investigation, the field had been tilled but not planted to a crop There was no vegetation cover in the field at the time of the site investigation Immediately adjacent to Weld County Road 23 5, and outside the plowed field there is a fringe of herbaceous ruderal weedy vegetation comprised of curly dock (Rumex craspus), lambsquarters (Chenopodium album), ironweed (Bassaa sieversiana), milkweed (Asclepias speciosa), and annual sunflower (Helaanthus annuus) There is no tree or shrub stratum present Exhibit J Page 1 Total vegetation cover in this area was estimated to be 35 percent, with height of principal 'deforms within this fnnge community as follows, trees, not found, tall shrubs, not found, low shrubs, not found, grasses, 12-18 inches, forbs, 12-20 inches This agricultural field is located withm the Altvan and Aquolls soil units The Natural Resource Conservation Service soil survey reports yields for common crops (1980) as follows, alfalfa hay (5 tons/acre), sugar beets (23 tons/acre), corn (160 bushels/acre), corn silage (33 tons/acre), dry pinto beans (2400 pounds/acre), onions (525 sacks/acre), and potatoes (325 hundredweight/acre) Pivot Irrigated Agriculture The pivot -irrigated agriculture community is located along Weld County Road 23 5 at the center of the proposed conveyor comdor This community extends from the dryland agricultural field 0 5 miles south to E 168th Avenue (Figure 3) This field had been planted to corn at the time of the site investigation with an estimated cover of 60 percent, and a height of 18 inches Immediately adjacent to Weld County Road 23 5, and outside the plowed field there is a fringe of herbaceous ruderal weedy vegetation compnsed of cheatgrass (Bromus tectorum), flixweed (Descuraania pannata), kochia (Kochia scoparaa), and horseweed (Conyza canadensis) There is no tree or shrub stratum present Total vegetation cover in this fnnge area was estimated to be 30 percent, with height of principal lifeforms within this fringe vegetation community is as follows, trees, not found, tall shrubs, not found, low shrubs, not found, grasses, 12-18 inches, forbs, 12-30 inches This agricultural field is located within the Dacono and Nunn soil units The Natural Resource Conservation Service soil survey reports yields for common crops (1980) as follows, alfalfa hay (5 5 tons/acre), sugar beets (20-25 tons/acre), corn (150-160 bushels/acre), corn silage (30-33 tons/acre), dry pinto beans (2400 pounds/acre), onions (525 sacks/acre), and potatoes (325 hundredweight/acre) At the north boundary of the pivot -irrigated agricultural field there is a small tailwater pond that contams a cattail marsh This feature is outside the proposed conveyor comdor Reclaimed Vegetation Community The proposed conveyor comdor crosses E 168th Avenue and proceeds east 0 1 mile to Tucson Street where the corridor then proceeds 0 5 miles south to its origin This segment of the proposed comdor flanks a water storage reservoir with a boundary that has been reclaimed to herbaceous vegetation under a Colorado Division of Reclamation, Mimng and Safety permit (M-2003-103) Vegetation along the conveyor corridor is dominated by smooth brome (Bromus anermas), western wheatgrass (Agropyron smathu), and curly dock (Rumex craspus), with a minor presence of cheatgrass (Bromus tectorum) and whitetop (Cardaria draba) There is no tree or shrub stratum present Exhibit J Page 2 Total vegetation cover in this fringe area was estimated to be 40 percent, with height of principal hfeforms within this fringe vegetation community is as follows, trees, not found, tall shrubs, not found, low shrubs, not found, grasses, 8-30 inches, forbs, 6-24 inches This vegetation community is located within the former loamy alluvial land, gravelly substratum and loamy alluvial land, moderately wet soil units Threatened and Endangered Species and Critical Habitat Potential habitat for the Ute ladies' -tresses orchid (Sparanthes dtluvialas), the sole threatened or endangered plant species known in the area, is not present within the project site The current proposed corridor does not include disturbance to Ute ladies' -tresses orchid potential critical habitat, therefore, no further evaluation was undertaken Exhibit J Page 3 Figure 1.

Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Amendment Application Exhibit S - 3 Geotechnical Stability Exhibit December 14, 2021 Mr Paul Conrad Aggregate Industries-WCR 1687 Cole Blvd , Suite 300 Golden, CO 80401 Re: Stability Analyses, Tucson South Amendment 2, DRMS Permit NO M-2004-044 Dear Mr Conrad 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 Tucson South Amendment 2 of the Tucson South Mine located in Weld and Adams Counties, Colorado Previous analyses regarding structure offsets at the mine cells were performed by Tetra Tech (2019, Amendment 1) The analyses performed herein address stability along the Amendment 2 conveyor alignment Additionally, we have performed rapid drawdown analyses on the west and east cells located along Tucson Street The site is located both north and south of the intersection of 168th Street and Tucson Street in Adams and Weld Counties, Colorado More specifically, the site is within part of Section 1, Township 1 South, and within part of Section 36 Township 1 North Both sections are in Range 67 West of the 6th Principal Meridian 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 south part of the site will be mined in two cells referred to as West and East cells A conveyor will transfer mine products from the mine to the Wattenberg Lakes Mine located approximately 1 5 miles north of the Tucson South Mine The majority of the conveyor route passes along unwed, nearly flat land that will not be subject to stability failure However, part of the conveyor will be located near the top of the clay liner which was constructed at the below grade, City of Aurora, Challenger Reservoir Review of the final grades of the reservoir, indicates the liner slopes approximately 3 honzontal to 1 vertical (3h 1v) and is approximately 30 feet in height Based on the original Tetra Tech (2019) analyses and the stability analyses discussed herein, the mine and conveyor route will be stable GEOLOGY The Site is located approximately 25 miles east of the eastern flank of the Rocky Mountain Front Range Younger sedimentary strata dip eastward off the Pre-Cambnan 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 (Trimble and Machette, 1979) indicates the near surface bedrock at the site is most likely the Denver Formation Trimble and Machette (1979) describes the Denver Formation as claystone, siltstone, and sandstone The regional mapping indicates the bedrock is overlain by the Post Piney Creek and Piney Creek Alluviums Trimble and Machette (1979) describes these alluvial deposits as sandy to gravelly alluvium GEOTECHNICAL CONDITIONS Based on the site investigations, the natural site stratigraphy generally consists of four main units 1) Overburden generally consisting of sandy clay and clayey and silty sands, 2) sand and gravel alluvial deposits that underlie the Mr Paul Conrad December 14, 2021 Page 2 overburden and overlie the bedrock, 3) a mud lens locally interbedded within the sand and gravel, and 4) bedrock usually consisting of claystone, sandy claystone with local areas of sandstone These units are described in more detail below Overburden Unit The overburden at the site typically ranges from sandy clay to clayey sand locally grading to silty sand This unit ranges from approximately 0 5 to 6 feet in thickness This unit is usually slightly moist to moist, very stiff to hard or medium dense to dense with the top 6 inches containing significant organics Of the samples tested, the percent passing the No 200 sieve ranged from 29 0% to 88 2% Atterberg Limits testing resulted in Liquid Limits of 22 to 68 and Plasticity Indices of 4 to 47 Sand & Gravel Unit The sand and gravel is present throughout the site usually underlying the overburden and overlying the bedrock Locally, this unit is present at the ground surface on the west part of the west cell This unit typically consists of gravelly, fine to coarse grained sand locally grading to sandy gravel Where gravels were encountered, the size was typically% to 3 inches This unit is typically medium dense to dense but is also locally loose This deposit ranges in thickness from approximately 8 feet to 50 feet The sands are clean with fines content (silt and clay) generally considered to be on the order of approximately 2 to 6 percent Local clay to clayey lenses were also logged within the deposit Mud Lens Unit The mud lens typically ranges from fine silty sand to sandy clayey silt, to silty clay This unit is most common west of Tucson Street but also is found on the east side of the street It is commonly interbedded within the sand and gravel unit 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 claystone or sandy claystone locally grading to silty, fine to medium grained, sandstone with local claystone seams For the claystone samples, the percent passing the 200 - sieve ranged from 51 7 to 95 percent For the sandstone samples, the percent passing the minus No 200 sieve ranges from approximately 11 4% to 29 2% Groundwater Groundwater was encountered in all the borings at approximately 5 to 13 feet below ground surface at the time of drilling 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 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 An underdrain has been designed around the west slurry wall to mitigate mounding and shadowing effects STRUCTURES WITHIN 200 FEET OF MINED AEAS Structures within 200 feet of the mine limits are listed in Exhibit S of the DRMS Amendment As mentioned above, stability analyses addressing off set from the mining were performed by Tetra Tech (2019) in the previous amendment The purpose of this stability analysis is to evaluate the stability along the conveyor route and rapid drawdown at the reclaimed Tucson South Reservoirs STABILITY ANALYSES Division of Reclamation and Mining Safety (DRMS) staff drafted a policy regarding stability analyses of neighbonng structures The draft summarizes adequate factors of safety (FOS) for non -critical and cntical structures All the structures considered in this analysis are considered critical structures The FOS are for both static and seismic (from an Mr Paul Conrad December 14, 2021 Page 3 earthquake) stability analyses For generalized strength assumptions and critical structures, a FOS of 15 is considered sufficient for static conditions and a FOS of 1 3 is considered suitable for seismic conditions The DRMS has not adapted a FOS for the rapid drawdown analysis The geotechnical practice in the area is to require a FOS of 1 2 for rapid drawdown This FOS evolved from the State Engineers Office (SEO), Dam Safety Branch (DSB) which required a 12 FOS for a rapid drawdown event at a jurisdictional dam The stability analyses performed herein were performed on cross sections descnbed below and shown on Figures 1, 2, and 3 The sections were analyzed under anticipated loading conditions 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 conditions and seismic stability under peak ground acceleration loads were performed for the three (3) sections along the conveyor A maximum horizontal acceleration of 0 067g was used at the site For the two (2) sections analyzed for rapid drawdown, the section was modeled high water levels (high pore pressure) within the reclamation slope to mimic a rapid drawdown event The cross-section locations were selected and analyzed as described below The sections met adequate FOS as summarized below in Table 1 The section locations are shown on Figure 1, 2 and 3 ► West Cell Rapid Drawdown This section evaluated the proposed setback from the Tucson Street easement from the West Cell boundary with a compacted reclamation slope A 500 psf load was applied to the road to mimic live traffic loads A mud lens was modeled based on actual findings in the area Outside of the slurry wall, the area was modeled with a high-water table assuming the wet season Inside the slurry wall the area was modeled with a high-water table within the reclamation slope to mimic rapid draw down conditions Potential failure surfaces were drawn from the edge of the Tucson Street easement The location of this section is shown on Figure 1 ► East Cell Rapid Drawdown This section evaluated the proposed setback from the Tucson Street easement from the East Cell boundary with a compacted reclamation slope A 500 psf load was applied to the road to mimic live traffic loads No mud lens was modeled based on actual findings in the area Outside of the slurry wall, the area was modeled with a high-water table assuming the wet season Inside the slurry wall the area was modeled with a high-water table within the reclamation slope to mimic rapid draw down conditions Potential failure surfaces were drawn from the edge of the Tucson Street easement The location of this section is shown on Figure 2 ► Challenger Clay Liner This section is on the east side of the Challenger Reservoir considers the tallest section adjacent to the conveyor The stability analysis for this section assumes a mine highwall sloped at 0 5 honzontal to 1 vertical (0 5h 1v) The clay liner slopes 3h 1v The overburden was modeled at 4 feet thick The underlying sand and gravel was modeled at 26 feet thick with a 4 feet thick interlensed mud lens One foot of residual strength bedrock was modeled over unweathered bedrock A 500 psf surcharge was modeled at the top of the liner near the conveyor to mimic the conveyor and traffic loading of maintenance vehicles Potential failure circles covered the clay liner slope The location of this section is shown on Figure 1 Mr Paul Conrad December 14, 2021 Page 4 ► C Muhler This section is on the northeast side of the Challenger Reservoir considers the tallest section adjacent to the conveyor and near the Muhler property The stability analysis for this section assumes a mine highwall sloped at 0 5 horizontal to 1 vertical (0

strength bedrock was modeled over unweathered bedrock A 500 psf surcharge was modeled at the top of the liner near the conveyor to mimic the conveyor and traffic loads Potential failure surfaces were drawn from the edge of the Muhler property The location of this section is shown on Figure 1 ► North Conveyor This section is on the west side of Weld County Road (WCR) 23 5 The area of this section is nearly flat with no mine highwall present in the area The overburden was modeled at 4 feet thick The underlying sand and gravel was modeled at 26 feet thick with a 4 feet thick interlensed mud lens One foot of residual strength bedrock was modeled over unweathered bedrock A 500 psf surcharge was modeled at the road and near the conveyor Potential failure circles were drawn from the utility corridor along the west side WCR 23 5 The location of this section is shown on Figure 3 MATERIAL PROPERTIES The material index and engineering strengths assumed in this slope stability report match those used in the Tetra Tech (2019) analyses and are discussed below Overburden The strength properties for the in situ 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 Moist Unit Weight (pct) Saturated Unit Weight (pct) Cohesion C' psf Friction Angle 0' 114 126 50 28 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 Moist

14, 2021 Page 5 Bedrock Bedrock below the alluvium is predominately sandy claystone with local claystone and 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 Moist Unit Weight (pct) Saturated Unit Weight (pct) Cohesion C' psf Friction Angle 0' Peak =124 Residual = 124 Peak =134 Residual = 134 Peak =100 Residual = 0 Peak = 28 Residual = 14 STABILITY ANALYSES RESULTS The factor of safety shown below in Table 1 is the minimum factor of safety

listed in the table above and the previous analyses performed by Tetra Tech (2019), neither the mine nor the conveyor will be a hazard to nearby structures provided the mine plan is followed and loading and subsurface conditions are as modeled Mr. Paul Conrad December 14, 2021 Page 6 LIMITATIONS Our review is based on regional geologic mapping, present mining and conveyor plans, and in part borehole data by others. Stability analyses were performed using typical strength parameters for the various strata in the critical sections. Should the mining or conveyor plans change, or subsurface conditions vary from those portrayed in this letter, we should be contacted to re-evaluate the potential affects on permanent man-made structures. The rapid drawdown analyses addressed herein are for structures as described herein. Further rapid drawdown analyses will be required when designing the final reservoir slopes. Please call with any questions or comments. Sincerely, Civil Resources, LLC Gary Linden, P.G.

the updated analysis performed to evaluate the minimum setback distance between the proposed mine limit and identified critical manmade structures near the site as required per the Mine Land Reclamation Board (MLRB) Construction Materials Rules 6 3 12(b) and 6 4 19(b) and the memorandum from the DRMS dated May 16, 20181 This slope stability analysis was not performed to evaluated the stability of highwalls, proposed mine slopes, proposed reclamation slopes, or infrastructure owned by Aggregate Industries The setbacks reported in this memo represent the minimum setback based on the physical and geotechnical input parameters for each model The required setback may be greater based on regulatory requirements The Tucson South Mine is comprised of approximately 250 acres, located a half -mile west of the City of Brighton, Colorado The site lies within the south half of Section 1 and the northwest quarter of Section 12 in Township 1 South, Range 67, West of the 6th Principal Meridian Land use around the site is aggregate mining, residential, and agricultural Tucson Street, a paved north -south road, bisects the proposed East and West Pits of the mine Colorado Highway 7 (E 160th Avenue) separates the proposed East and West Pits from the proposed Southwest Pit The South Platte River forms the eastern border for the proposed mine and the Brighton Ditch forms the western border of the proposed mine The site is in the alluvial valley of the South Platte River Geologic mapping indicates that the mine is located on an alluvial terrace corresponding with the Piney Creek and Post Piney Creek alluvium2 The bedrock underlying the alluvium may be the Arapahoe Formation, which consists of claystone and sandstones A total of 130 boreholes have been drilled onthe site Drilling logs indicate the general subsurface profile consists of an average of three feet (one to ten feet) of silty sand overburden, overlying an average of 23 feet (five to 46 feet) of sand and gravel, overlying the bedrock A mud lens was found in the area, mainly in the West and Southwest Pits of the proposed mine Groundwater was encountered while drilling in 2004 at depths between eight and 12 feet below the ground surface Monitoring well readings from December 2003 to August 2004 have water levels between four and 16 feet below ground surface Cazier, T (2018, May 16) Re Factors of

UTETRA TECH A slope stability evaluation was performed by Tetra Tech for the Tucson South mine in November 20043 The evaluation used the (previously required) required minimum factor of safety value of 1 0 and analyzed sections for a total of 14 critical structures surrounding the Tucson South mine A seismic analysis was not required by the DRMS as part of the slope stability analysis in 2004 The 2004 evaluation was used as the basis for an updated slope stability analysis performed by Tetra Tech in 2018 l In p'reparatio`n of an amendment to the Tucson South permit application in2018 Tetra Tech performed an updated slope stability analysis Critical structures within 200 feet of the mine in 2018 were reevaluated and seven manmade structures were identified as requiring slope stability analysis A memorandum dated November 9, 20184 describes the results of the analysis that was prepared and submitted to Aggregate Industries for their use A slope stability analysis preformed in February of 2019 to determine required minimum setbacks from permanent manmade structures around the Tucson South Mine if mine highwalls were excavated at a slope of 0 5H 1V and not reclamation slopes were not constructed concurrently This updated stability analysis was performed using GeoStudio 2018 (Slope/W Define) computer software5 The software is capable of computing factors of safety for a range of materials using finite element analysis Spencer's method of slices6 was used to calculate the safety factor for the individual failure surfaces Several assumptions were made for the models including o Surficial geology was modeled based on stability models and borehole data from 2004 • Geologic layers are generally horizontal in the subsurface ® The highwall will be concurrently reclaimed, or mined only at 3H 1V slopes O The West and East pits will be mined after the slurry wall is installed and will be dewatered as needed • The slurry wall (designed by others) will be keyed into bedrock ® No excess pore pressure build up will occur within the soil strata • No slurry wall will be constructed around the South pit • The South pit will be wet mined • The slurry wall is setback a minimum of 20 feet from the crest of the mine slope/reclamation slope © The slurry wall will be constructed a minimum of 15 feet from any structure or easement Both a reclamation slope and a mine slope were considered during this stability analysis for each section analyzed in February 2018 A reclamation slope is a slope built of fill material, typically overburden found at the site, used to stabilize the mine highwall A mine slope is a slope cut at a stable grade leaving the native material in place The grade modeled for both the reclamation slope and the mine slope was a 3H 1V The highwall, from the February study, is assumed to be 0 5H 1V 3 Goss, C (2004, November 22) RE Revised Tucson South Proposed Gravel Mine Slope Stability Analysis, Tetra Tech RMC Job No 19-3919 019.00 (T

within 200 feet of proposed mining were modeled during this evaluation A critical structure is defined by the DRMS as a manmade structure that poses a potential human safety risk, major environmental impact, and major repair cost if the slope were to fails A mud lens was modeled in sections evaluated where a mud lens was present at the site based on borehole information prepared for the 2004 evaluation The cross sections and profiles were created using Figures 1 to 6 These figures show the proposed site layout and locations to critical structures, easements, and the topography in the area Sections were created at each of the critical structures in the vicinity, and the estimated depth to bedrock from the subsurface study was used to create the profile for the slope stability analysis

Proposed Gravel Mine Slope Stability Analysis November 8 2019 5.0 LIMITATIONS The findings presented in this memorandum are based on information from previous geotechnical investigations at the site and strength parameters of the modeled materials provided by the Colorado Division of Minerals and Geology in 2004. Tetra Tech should be contacted if the mining plans change or if the subsurface conditions vary from the descriptions here as reevaluation may be necessary to the investigate potential effects of the changes on the factors of safety for the critical structures determined in this evaluation. Factors of safety for this evaluation were limited to effects at the critical manmade structures and were not an evaluation of the mining highwall and/or reclamation slopes.
