requirements outlined in Section 6 4 4 of the Colorado Mined Land Reclamation Board Construction Material Rules and Regulations Mining Plan The proposed mining plan does not differ from that previously approved by the DRMS The proposed amended Mined Land Reclamation Board (MLRB) Tucson South Resource mine area is approximately 1 5 miles south of the Aggregate Industries Wattenberg Lakes Mine (M-2004-051), which supplies aggregate construction materials to much of southern Weld and western Adams counties The amended area will be a conveyer easement that will allow for export of mined material from the Tucson South Resource to the Wattenberg Lakes Mine The amended Tucson South Resource Permit Boundary contains substantiated aggregate resources to continue the supply in this region of Colorado Supplementing resources at the Wattenberg operation, new supplies from the amended Tucson South Resource will continue to provide construction materials to meet the Front Range Colorado demand Introduction and Overview The amended Tucson South Resource permit area is currently owned by Aggregate Industries-WCR Inc , the City of Aurora, Adams County, Yoshi and Suzu, LLLP, Dorothy and James Struck, and Toby Struck The permit area consists of dryland and irrigated agriculture, a reclaimed gravel resource, a partially reclaimed gravel resource, and a former greenhouse growing operation Above ground structures at the greenhouse have been demolished and removed from the site Below grade features will soon be demolished and hauled from the site The previously permitted property is located north of Colorado Highway 7, bisected by Tucson Street The amended area, providing an area for the conveyor easement, is along the west side of Tucson Street, the south side of 168th Ave (aka Weld County Road 2), and the west side of Weld County Road 23 5 before crossing over Weld County Road 23 75 entering the Wattenberg Lakes facility Aggregate Industries has entered into agreements with the City of Aurora, Yoshi and Suzu LLLP, Dorothy and James Struck, and Toby Struck to allow for the conveyor easement crossing Mining of the Tucson South Resource is proposed to happen in two phases The West Area (Phase 1) is located north of Colorado Highway 7 and west of Tucson Street, and the East Area (Phase 2) is located north of Colorado Highway 7 and east of Tucson Street Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application Exhibit D -1 In general, drainage on the site flows toward the South Platte River to the north and east of the property The drainage pattern in the West Area either flows to local low spots on the property, is conveyed off -site to the north, or is conveyed via an irrigation return ditch to the East Area The East cell generally drains north and east to the river via overland flow or through existing channels and ditches left by historic disturbance Drainage at the amended area flows to local low spots before being conveyed to existing gravel mines locate north of the site With this project the Permit Boundary and the Affected Lands are different areas, as explained below Permit Boundary Area The proposed Permit Boundary contains the following areas as shown on Exhibit C-1 and Exhibit F-1 o Tracts of land owned by Aggregate Industries-WCR, Inc referred to on our mapping as Tracts A, B, D, E, F, H, and M © Tracts of land owned by the City of Aurora referred to on our mapping as Tracts C, G, K, and N • Tucson Street right-of-way referred to on our maps as Tract L • East 168t Avenue right-of-way referred to as Tract O • Land owned by Yoshi and Suzu, LLLP referred to on our maps as Tracts P and Q • Land owned by Dorothy and James Struck is referred to as Tract R e Land owned by Toby Struck is referred to as Tract S Affected Land The Affected Land includes all Tracts described in the Permit Boundary except Tract K, which is owned by the City of Aurora This area is located east and west of the Brighton Ditch and will not be disturbed by the mining activities and reclamation operations Therefore, it was excluded from the Affected Land Aggregate Industries had previously planned to mine a South Cell which was removed from the permit with the approval of Acreage Reduction Request 2 (AR -02) Technical Revision 2 (TR-02) updated the Mining and Reclamation maps to reflect the removal of the South Cell Existing Land Uses The proposed Tucson South Resource mine currently consists of dryland and irrigated agriculture, one house (with outbuilding) and the former greenhouse growing operation described above A Todd Creek water well and associated United Power overhead electric line on the west side of the West area will also be removed Aggregate Industries purchased the Todd Creek water well parcel and entered into an agreement to relocate the well to an area adjacent to the river The relocated well is shown on Exhibit C-3 The applicant has contacted United Power regarding removal Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application Exhibit D - 2 of the existing electric service and will forward the documentation regarding removal of the service line upon receipt There is one rural residential property located adjacent to the mine on Tucson Street, several more rural residential properties located south of Tracts A and H and Highway 7, and several more rural residential properties located along Baseline and Weld County Road 23 5 along the conveyor alignment In addition, there is a developing residential subdivision located west of Tract K The South Platte River corridor receives recreational use and the City of Brighton operates a parks and wildlife recreational area north of Highway 7 and east of Tract H along the west side of the South Platte River Improvements owned by the applicant or property owners that are located within the Permit Boundary Area such as un-improved roads, fences, alluvial water wells and associated pumps, houses and outbuildings, irrigation ditches and laterals, may be removed or relocated during mining and reclamation There were two oil and gas wells and associated facilities located on the property The wells were plugged and abandoned per Colorado Oil and Gas Conservation Commission standards and the associated facilities have been hauled from the site Structures, easements, or rights - of -ways not owned by the applicant or property owner will not be disturbed without prior permission (see Exhibit C Pre -Mining Maps) None of the easements, rights -of - ways, or associated structures are expected to be negatively affected by mining or reclamation operations Nature of Deposit to be Mined Test borings indicate a layer of topsoil and overburden ranging from 1 to 11 feet in depth with a typical overburden depth of 5 feet The typical depth of topsoil to be removed is 6" In the western part of the site, the topsoil has been tilled until recently and likely contains a significant amount of organics The overburden is underlain by an aggregate layer with a thickness ranging from 0 to 46 feet with a typical thickness of 25 feet In some parts of the sites, the aggregate layer contains a 2- to 9 -foot thick mud lens The total depth to bedrock from the surface grade ranges from 5 feet in the west to approximately 50 feet in a paleochannel in the eastern part of the site The typical depth to bedrock is approximately 27 feet over most of the mine area The aggregate layer overlies sedimentary bedrock of the Denver Basin A soils report is attached in Exhibit I herein for reference Mine Phasing Aggregate Industries anticipates mining and reclaiming the proposed Tucson South Resource site in approximately 5 to 8 years The rate of mining and overall life of the mine is dependent on several factors including product demand and operational needs Test borings have verified that commercial deposits of sand and gravel exist up to 50 feet below the surface of the ground In addition to the commercial sand Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application Exhibit D - 3 and gravel materials, clay, silt, and other non -marketable materials excavated from the proposed permit area will be used on -site for reclamation The mining plan currently includes mining in two phases Mining may occur simultaneously in more than one phase The actual sequence may change depending on market conditions, operational needs, or site conditions • West Area (Phase 1), is located north of Highway 7 and west of Tucson Street and included Tracts A, B and C • East Area (Phase 2) is north of Highway 7 and east of Tucson Street and includes Tracts D, E, F, G and H Tracts N, O, P, Q, R, and S will contain the conveyor to export product off -site to the Wattenberg Lakes Site and will be used during all mining phases Mining will begin in the West Area (Phase 1) Once mining is complete in the West Area, mining will commence in the East Area (Phase 2) All necessary permits will be obtained A summary of mining phases is presented in the table below Processing and sale of the material will occur on the Platte Valley site (M-1989- 120). Overburden from the West and East Areas will be used to reclaim the cells If there is excess overburden material, the material will be conveyed to the Platte Valley site and Wattenberg Lakes site for reclamation A slurry wall will be constructed around the East and West Areas prior to exposure of the water table The slurry wall has been designed and is attached to this exhibit Mine Phasing Summary Mine Phase Total Acreage To be Duration (years) West 72 0 4 East 83 8 4 Tot 155.8 8 Mining Methods The method of mining used within the permit boundary U The slurry wall liner for the West and East Areas will be installed prior to exposure of ground water at the site Once the slurry wall is installed the West and East Areas will be dewatered The deposit will be dry mined using dewatenng trenches and pumps within the slurry lined area Prior to excavation of each mining phase, trenches will be cut along the perimeter of the excavation to begin dewatenng the sand and gravel material The trenches will extend through the overburden and alluvium to bedrock Pumps will be used to remove the groundwater that drains from the deposit within the lined excavation If necessary, water from the trenches will be circulated through a settling pond prior to being discharged to adjacent drainage ditches and/or the Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application Exhibit D - 4 South Platte River (see Exhibit C Mining Maps) As excavation begins, the mining cell and dewatenng trenches on the floor will continue to collect any water entering the lined Areas, keeping the deposit material relatively dry The collected water will be directed to settling ponds within the Areas or near the final discharge point to South Platte River It is anticipated that dewatenng will be completed within the slurry wall lined mining area within 12 months and dewatenng throughout the life of the mine will be limited to precipitation, stormwater runoff that drains into the mining area, and minor amounts of groundwater. Earth Moving Setbacks from the top of slope of each area to the proposed permit boundary or man- made structures not owned by the applicant or by agreement with the structure owner will generally be 30 feet or greater Specific setbacks from Highway 7 and Tucson Street also account for future expansion of the roadways The perimeter setbacks from the structures are shown on Exhibit C - Mining Maps These setbacks were determined in combination with Adams County regulations and the Slope Stability Analysis prepared by Tetra Tech provided herein in the Geotechnical Stability Exhibit. The setbacks reflect the Factors of Safety in the Proposed Slope Stability/Geotechnical Analysis Policy in the DRMS memorandum dated May 16, 2018 Areas to be mined will be prepared by removal of topsoil and overburden Each preparation area may be as much as 100 feet wide along the anticipated mining face Usually, only enough area is stripped and prepared to provide the estimated needs for the next 10 to 14 months of mining Surface topsoil material will be stripped separate from the underlying, deeper subsoil or overburden material This topsoil layer contains most of the soils organic matter and will be stockpiled separately for use in reclamation Once the topsoil has been removed, the rest of the overburden will be stripped and stockpiled separate from the topsoil When the alluvial material is exposed and sufficiently dewatered, the aggregate material will be recovered using equipment typical for sand and gravel mining operations In the West and East Areas, the aggregates will be mined using conventional dry mining methods Earth moving equipment may include, but is not limited to, dozers, loaders, scrapers, and excavators as mining progresses to a depth of 20 to 50 feet below the surface The alluvial material is an unconsolidated deposit and, therefore, no blasting is required The aggregate material from the Areas will be temporarily stockpiled within the various Areas, conveyed to the staging area, or immediately transported off -site for processing During mining and reclamation activities, watering trucks for dust control will be used as needed Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application Exhibit D - 5 The active mining face will extend no more than 2,300 feet in length During mining and prior to reclamation in the West and East Areas, the mine walls will be a nearly vertical to 1/2H 1V slope (see Exhibit C, Mining Maps) Mining will progress down to the depth of quality aggregate material Backfilling and/or grading of side slopes may follow behind the mining activities before mining in the Area is complete Concurrent reclamation will be practiced when the highwall reaches the mine limit During the flood season April 1 through September 30 and when the highwall is within 400 feet or less of the river the highwall will be no steeper then 3H 1V As mining progresses, topsoil, overburden, and non -marketable materials will be removed and stockpiled for use in reclamation activities Overburden from the West Area and East Areas will be used in reclamation. Should there be excess overburden on these cells, the material will be conveyed to the Platte Valley site for reclamation or to be sold During mining in the West and East Areas, topsoil will be segregated and stockpiled in the locations shown on Exhibit C Mining Maps, i e outside of the Floodway As mining progresses, overburden will be taken directly to mined out slopes for use in reclamation Topsoil and overburden stockpiles will be configured to have side -slopes no steeper than 3H 1V If the stockpiles are inactive for more than one growing season, such as the stockpiles used for screening, they will be seeded with the fast-growing grass seed mixture below Stock Ile Grass Seed Mixture Grass Species Rate (#PLS/ac Luna Pubescent Wheatgrass 15 0 Amur Intermediate Wheatgrass 15 0 Rates are for broadcast seeding Other than those used for screening, long-term stockpiles are not anticipated Temporary stockpile materials will continually be used for reclamation and the stockpiles will likely be disturbed on a frequent basis and seeding the stockpiles may not be practical during the operation If stockpile seeding is not used, surface roughening will be maintained to limit wind and water erosion Most of the proposed Tucson South Resource Permit Boundary Area is within the regulatory floodplain of South Platte River Because of floodplain regulatory restrictions, stockpiling will occur within a mining Area whenever possible with the top of stockpile elevation lower than the pre -project grade Stockpiles within the modeled floodplain above the existing ground surface will generally be created parallel to potential South Platte River flood flows The stockpiles will be no longer than 300 feet, with minimum spacing of 100 feet between stockpiles for flood flows to pass (see Exhibit C, Mining Maps) The screening stockpiles along Highway 7 as Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application Exhibit D - 6 indicated by modeling, are located in areas where placement is not expected to impact floodplain water surface elevations Consequently, there is no restriction on length or orientation The impacts of stockpiles on floodplain water surface elevations is presented in the Floodplain Use Permit application approved by Adams County Additional mining and reclamation procedures will be used within the regulatory floodplain to mitigate impacts from potential flood flows Flood season is considered to be April 1 through September 30 The southern and eastern slopes of each area will either be maintained at 3H 1V during the flood season during mining or concurrently reclaimed at 3H 1V with reclamation backfill This restriction only applies for areas within 400 feet of the South Platte River in accordance with DRMS policy If flood waters reach the mining Areas prior to complete reclamation, the 3H 1V slopes will allow more controlled flow into the Areas while reducing the potential for head cutting and capture of the South Platte River A Floodplain Use Applications have been approved by Adams and Weld Counties for this project Adams County may request review and comment from Mile High Flood District (MHFD) Comments and revisions from the County or the MHFD will be incorporated into the final Floodplain Use Permit The table below illustrates a point in time when the mining disturbance could be at its maximum At the proposed Tucson South Resource site, it is assumed that the mining disturbance will be at its greatest when the East Area mining is nearly complete That will be a time when the slurry walls are installed and, topsoil replacement and initial seeding will be completed for the West Area Aggregate lndustnes — Tucson South Amendment — MLRB 112 Permit Application Exhibit D -

2 Final Proposed Land Use The current land use for the Tucson South Resource property is a combination of partially reclaimed mining area, reclaimed mining area, and dryland and irrigated agriculture, upland meadow and a City of Aurora water facility The City of Aurora water facility (located outside the Affected Lands, west of the Brighton Ditch) will be removed from the Permit Boundary at a future date and continue to operate The proposed final land use for the remainder of the property is lined municipal water storage for the West cell and the majority of the East cell, upland meadow on the northern portion of the East cell and conveyor alignment along the City of Aurora Challenger Reservoir, and irrigated and dryland agnculture along the Weld County portion of the conveyor alignment Surrounding land uses include Water storage to the north, rural residential and agriculture to the south and along the Weld County portion of the conveyor alignment, Town of Brighton wildlife conservation area and the South Platte River to the east and water storage and suburban residential to the west The lined storage and upland meadows are compatible with existing and future adjacent land uses This property lies within the City of Brighton Urban Growth area and is designated as natural resource conservation and flood plain on the 2016 Future Land Use Map General Overview of the Reclamation Plan Types of Reclamation acres Reclamation of the proposed permit area will contain three land forms, uplands, agricultural, and lined, open water reservoirs Cottonwoods and shrubs will be planted along the South Platte River on the eastern side of the east cell Timing and installation of the plantings will be coordinated with the Urban Drainage and Flood Control District It is anticipated that these plantings will be established as part of the concurrent reclamation of the site Plantings will be installed when mining commences in the East Cell (Phase 2) Plantings will be installed by a reclamation contractor in September and hand watered until the ground freezes Plantings will be monitored in the spring to make sure they are leafing out, replaced as necessary to provide the quantities as originally installed and watered as necessary through the first three growing seasons to establish Common Name Botanical Name Planting Size Quantity Plains Cottonwood Populus deltoides 10 gallon 36 American Plum Prunus americana 1 gallon 40 Choke Cherry Prunus virginiana 1 gallon 40 Western Sand Cherry Prunus besseyi 1 gallon 40 Coyote willow Salix exigua 1 gallon 40 The primary reclamation process will be backfilling the slopes of the mined -out areas to be reclaimed as reservoirs backfill of the partially reclaimed area on the northern end of the East cell to create an upland meadow Overburden, and non -marketable materials from the site will be used as backfill As mined out cells are backfilled, rough grading will establish the slopes and elevations necessary to facilitate the appropriate land form for that specific area of the site In upland areas backfill materials will be placed to an elevation near or below the premining surface elevation For areas where reservoirs are to be located, backfill will be used to create pond side slopes Pond depth may extend all the way to bedrock and side slopes will be 3H 1V or flatter Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application Exhibit E - 3 Except for pond slopes below normal average highwater surface elevation, all areas disturbed by mining activities will be prepared with topsoil to a minimum of 6 to 12 inches and revegetated during reclamation Revegetation will generate a blend of upland grass species Given suitable precipitation, seeding should produce good vegetation cover over much of the reclaimed site Roads not necessary for future access and other disturbed areas will be reclaimed with topsoil and overburden replacement and vegetative cover to stabilize the areas and minimize erosion Reclamation Measures/Materials Handling All available topsoil and overburden material will be used for backfilling and reclamation Earth moving equipment may include, but is not limited to dozers, loaders, scrapers, and excavators Additional farm equipment for grading and seeding may be used for revegetation activities Matenals Handling- Backfilhng The site will be concurrently reclaimed to create the water storage reservoirs Compaction for the reservoir side slopes at this site will be 95 percent (or better) standard proctor When an area is completely mined out from grade to bedrock, each section approximately 800 -foot -wide (or approximately 30 acres), will begin side slope construction while the next contiguous area or consecutive phase is beginning mining Due to the floodway, there is limited space for stockpile placement at this site, by concurrently reclaiming, as an area is being prepared for mining, the overburden and topsoil can be stnpped and immediately placed, or stockpiled in the previously mined area, limiting the material handling It is estimated that within 6 months of an area being completely mined, it will be reclaimed Backfilling of mining cells and other reclamation activities will be concurrent with mining Topsoil, overburden, and non -marketable material excavated during mining will be used almost immediately The reserved topsoil and overburden will be used to create the finished grade prior to revegetation Small temporary stockpiles may be created within or along the edge of the mining cells When enough material is available in the stockpile, the material will be graded into the previously mined areas Locations of topsoil and overburden stockpiles are shown on Exhibit C Mining Maps Material may be imported for reclamation if on -site material is insufficient to create the reclaimed pond slopes Prior to receiving any backfill material from outside the proposed permit area, the operator will provide notice with information that includes the backfill location and volume of off -site material to be used, an affidavit certifying that the material is clean and inert, an approximate time frame for backfilling with off -site material, and an update regarding material placement procedures and the final reclamation configuration The on -site or offsite backfill material used will not contain known toxic or hazardous materials All backfilling and grading will be done to stabilize the material and control erosion Final grading and seeding will be done as soon as possible after backfilling, grading, and top soiling have been completed The reclamation will not leave high walls on the property In addition, there will be no auger holes, excavations, or shafts left on the property Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application Exhibit E - 4 Materials Handling — Grading Once backfill is placed to the approximate final grade for upland meadow, pond side slope creation, or agricultural reclamation, the area will be rough graded to establish final elevations, slopes, and transitions Final grading will include addition of topsoil and surface preparation for revegetation Special attention shall be given to transitions from reclaimed areas to undisturbed land The final topography will not create new surface drainage directed onto adjacent properties Reservoir side slopes will include the steepest reclaimed grades on the site, potentially as steep as 3H 1V The side slopes will be graded smooth to accommodate future maintenance of the lined reservoirs The reclamation will not leave high walls on the property Matenals Handling- Soil Bentonite Slurry Wall The proposed slurry wall will provide a vertical low permeable cutoff between alluvial groundwater outside of mining cells and water stored below -grade inside of mining cells Slurry walls (also known as slurry cutoff walls) are non-structural liners constructed to provide a primary low permeability liner and isolate a mining cell from the existing alluvial aquifer Soil-bentonite slurry walls are a very common type of liner constructed in Colorado Construction of a soil-bentonite slurry wall liner is underway at the Tucson South Resource East and West cells Once the liners are constructed and meet an SEO required 90 -day minimum leak test, lined water storage reservoirs located north of State Highway 7 will be available for use Aggregate Industries contracted with Civil Resources, LLC to provide a final design of a soil-bentonite slurry wall liner for Tucson South The final design is submitted with this amendment Al has awarded the contract and construction activities commenced in October 2021 The slurry wall will be constructed with a long reach excavator or other suitable trenching equipment A trench approximately 3 feet wide and 100 to 150 feet in length will be excavated through the existing alluvium and several feet into the underlying claystone and sandstone bedrock The total slurry wall depth vanes from top to bottom based on the existing geology but will average 30 feet deep for this project The trench will be flooded with fresh bentonite slurry to stabilize the excavation during construction of the slurry wall A mixture of alluvium excavated from the trench, dry bentonite, and clayey supplemental fines will be mixed at the surface and placed into the trench in a semi -fluid state typically with a bulldozer and/or second excavator The slurry in the trench is displaced by the soil- bentonite backfill as the excavation of the trench is advanced Once the excavation of the trench followed by the backfill operation is complete, the soil-bentonite backfill consolidates and behaves as a soft clayey soil The top of the slurry wall is typically capped with a few feet of clayey soils to speed up the primary consolidation, identify the approximate location of the slurry wall, and provide clayey soils to fill depressions due to the consolidation of the slurry wall Other considerations required for successful construction of a soil-bentonite slurry wall include a stable, relatively flat gently sloping (i e less than 1 percent parallel to the wall) construction platform along the proposed slurry wall alignment Construction of the construction platform along the slurry wall alignment is primarily on stable, native soils found at the site and should not present a challenge for construction equipment There are narrow areas proposed for the construction platform at this site However, the narrow areas are relatively short and soil-bentonite slurry wall construction activities should not be greatly affected by these sections Once soil-bentonite slurry wall construction is Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application Exhibit E - 5 complete, the construction platform will be final graded for stability and an operations and maintenance access route will be left in place The route will be reclaimed and stabilized as a low traffic dirt road Gravel Pit Lining Criteria Gravel pit liners are designed with the goal of meeting the leakage requirements outlined in the State of Colorado's document entitled "State Engineer Gu►de!nes for Lining Criteria of Gravel Pits,"August 1999 As described in the guidelines, the intent of the soil-bentonite slurry wall design is to reduce the groundwater inflow (leakage rate) into the lined below -grade mining cell to at or below the Design Standard The Design Standard is defined in the guidelines as the leakage rate that is not greater than 0 03 ft/day multiplied by the curtain area of the soil-bentonite slurry wall (i e the length of the perimeter wall in feet multiplied by the average vertical depth of the wall as measured from the ground surface to the mine cell floor along the toe of the cell side slope), plus 0 0015 ft/day multiplied by the area of the floor encompassed by the soil-bentonite liner The guidelines allow for a liner to meet a performance standard which is three times the Design Standard and operate as a lined water storage cell Monitoring and release requirements are increased from monthly reporting to weekly reporting for liners that meet the Performance Standard At the completion of construction, the liner is subjected to a minimum 90 -day leak test as described in the guidelines Topsoil and Revegetation Revegetation will only include grass seeding of disturbed areas No tree or shrub planting is planned around the perimeter of the reservoirs In areas reclaimed for agricultural purposes, the site will be graded with the native topsoil and planted with crops at the discretion of the property owner Where required, topsoil will be replaced to a depth of 6 to 12 inches Topsoil will be placed after backfilling and rough grading is completed As an area is reclaimed, runoff or excess water from adjacent areas will not be allowed to flow over slopes being graded and seeded If needed, berms or channels will be constructed to divert excess water and dispose of it in a safe and non -erosive manner ', Seeding of disturbed areas will be done as areas are finished with preparation including grading and topsoil spreading Seeding will be most successful if done between mid - November and the end of April Seeding can be performed in May, if necessary, but after May it is not advisable to plant Seeding before November is not advised as the potential for a warm growth environment and early germination would likely result in a major failure of the revegetation and require reseeding Fertilizer may be applied to re -soiled areas in a manner that will encourage emergence and survival of the grasses without encouraging competition from weeds Starter fertilizer can be applied before, or at the time of, seeding If necessary, full fertilization will be applied after emergence Fertilizer mixtures will be based upon soil tests made on samples taken from re -soiled areas prior to seeding If a significant invasion of noxious weeds occurs after seeding, the weeds will be mowed before they can go to seed The areas will be mowed periodically for additional control Aggregate lndustnes — Tucson South Amendment — MLRB 112 Permit Application Exhibit E - 6 as needed Mechanical control will be used as a first priority Chemical methods will only be used if no other alternative produces acceptable results Periodic inspection for noxious weeds, at least once a year early in the season, will be done The weed inspection will search for not only the expected species but also any new List A or List B species introductions It is likely that non -noxious and List C species will also be found Non -noxious weeds, which are often native invaders, do not need to be controlled, but if the population of a List C species is controllable then it will be included in the control program List C noxious species are problematic but are usually not as serious as List B species Specific information regarding weeds is included in the Biological Resource Inventory included with Exhibit H Aggregate Industries utilizes an integrated weed management protocol to manage weeds on their active mining sites this protocol includes 1. Management Objective Manage noxious weeds and plant pests within the permit area 2. Weed Species to be Controlled Aggregate Industries- WCR, Inc (AI) will control those plant species identified by current State statute or regulation as noxious Plant pests are defined as those biological species that significantly predate the desirable vegetation of the project site 3 Weed Management Actions • Monitoring The presence of noxious weeds and plant pests will be monitored annually, at which time weed control efforts will be reviewed and specific management measures adjusted as necessary Management measures will be undertaken where a single or combination of noxious weed species or plant pests comprises or shows a deleterious effect to the live vegetation cover in the mitigation area as determined by observations of a revegetation or weed control specialist • Control Measures Al will contract with a licensed herbicide applicator/weed management specialist to implement the weed management plan Noxious weeds or plant pests may be controlled by any combination of cultural, mechanical, biological, or chemical measures Weed control measures will be developed specifically for the noxious weed species encountered and in consultation with Adams County, local weed control district and/or the Colorado State Department of Agriculture as necessary Topsoil slated for removal from the site will be treated with a long- term residual pre -emergent or post -emergent herbicide to reduce noxious weeds prior to removal Al will conduct an aggressive mowing program the first year following revegetation, withholding herbicide use until the following year to avoid damaging new seedlings. Herbicides will be applied by a licensed commercial applicator Stockpiles that remain undisturbed for more than one season will be seeded with a temporary cover crop Where noxious weed control measures cause disturbance to the remaining vegetation, seeding or planting of desirable replacement vegetation will occur during the first normal planting or seeding season after weed control measures have been implemented and deemed successful Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application Exhibit E - 7 • Contact Person(s) During mining, the Operations Manager at the site will be the contact person for weed control When mining is completed, the weed control contact person will be Aggregate Industries' operations staff at the corporate office in Golden, Colorado Aggregate Industries will be responsible for weed control until the site is released by DRMS At that time, responsibility for weed control will transfer to the land owner The grass seed mix, composed of a long lasting and regenerating native upland seed mixture, will be used in upland areas where no future irrigated/dryland agriculture or other development is anticipated The native open space seed mix recommendation is presented below Upland Meadow Grass Seed Scientific Name Variety % of Mix Application Rate (PLS/acre) Big Bluestem Andropogon gerardii Kaw 15% 1 7 Blue Grama Bouteloua gracilis Hachita, Lovington 10% 0 3 Green Needlegrass Nassella vindula Lodom 15% _ 15 Sideoats Grama Bouteloua curtipendula Vaughn, Butte 10% 1 0 Switch grass Panicium virgatum Blackwell 20% 2 0 Western Wheatgrass Pascopyrum smithii Arnba, Barton 30% 4 8 Total 11.3 *Application rate is for drill seeding If seed is to be broadcast, the application rate will be doubled Temporary Stockpile Vegetation Luna Pubescent Wheatgrass- 15 lb /ac Amur Intermediate Wheatgrass -

3 exposed groundwater allowed pursuant to the approved well permit is approximately 10 5 acres Evaporative losses were calculated as the difference between gross evaporation and effective precipitation The NOAA Technical Report NWS 33, Evaporation Atlas for the Contiguous 48 United States (U S Department of Commerce) was used to determine the site's average annual gross evaporation of 43 inches Precipitation was obtained from the Colorado Climate Center for the Brighton weather station The gross annual precipitation for this site was estimated to be 14 55 inches Effective precipitation was calculated as 70 percent of gross precipitation, thus, the average annual effective precipitation was determined to be 10 19 inches The maximum total annual evaporative consumptive use at the site is estimated at 28 7 acre-feet The maximum annual production at the site is estimated at 1 25 million tons The anticipated maximum volume of water lost in the material hauled off -site is 60 acre-feet per year The maximum annual operational water consumptive use due to the mining operation is estimated at 65 acre-feet per year Maximum dust control requirements at the site are estimated at 5 0 acre-feet per year The mine will be at the highest production during the months of May through August, and in combination with the weather, this period will require the greatest amount of dust control The mine will be in production year-round and therefore dust control may be required during all months The maximum annual consumptive use from mining at the site authorized by the well permit is 93 7 acre-feet per year as shown in the following table Evaporation 28 7 ac -ft Moisture Retained in Product 60 ac -ft Dust Control 5 ac -ft Total 93.7 ac -ft It is not anticipated that additional water will be required for reclamation of the site Once reclamation is completed, the City of Aurora will use decreed water rights to fill the ponds (4) The Operator/Applicant shall indicate the projected amount from each of the sources of water to supply the project water requirements for the mining operation and reclamation Aggregate Industries (Al) currently maintains a substitute water supply plan approved through the Office of the State Engineer for its mining operations along the South Platte River and its tributaries Until the liners surrounding the West and East Areas of the project have been approved by the State Engineer, replacement water will be provided pursuant to Al's Combined Substitute Supply Plan (CoSSP) The plan includes this site Sources of water currently in the CoSSP include historic consumptive use credits from several area irrigation ditches, water from the City of Westminster, and other water currently available to Al under existing lease agreements Under the CoSSP, replacements are made to the South Platte River at various locations including the Metro Wastewater Treatment Plant outfall structure located upstream of the property Transit loss associated with the replacement water sources is assumed to be 0 5 percent per mile The following is a list of some of the sources of water currently Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application Exhibit G - 4 approved by the State Engineer for use in Al's CoSSP 1 1998 Effluent Lease (1998 Lease) with the City of Westminster. The 1998 Lease has been used as a replacement source for individual SSP's that have been approved in the past This is a perpetual lease that provides 0 28 cfs of fully consumable water every day of each year and an additional 0 17 cfs of fully consumable water every day from October 15th to June 30th during each year at the outfall of the Metro Wastewater Treatment Plant The lease provides 294 79 acre-feet annually A small amount of this water is dedicated to the decreed augmentation plan in Case No 07CW198, the remainder is available for use in the CoSSP 2 Historic Use of 62 shares of the Fulton Ditch. This has an estimated average annual consumptive use of 116 05 acre-feet The technique of quantifying historic use of 29 shares of Fulton Ditch water was approved for use on November 12, 1999, for the SSP and submitted to the State Engineers Office on March 24, 1999, for the Fulton Lakes Pit The decreed historic consumptive use is 1 75 acre-feet/ share The consumptive use credit from the Fulton Ditch shares suffices to adequately replace out - of -priority depletions and return flow obligations in the months of June through August 3. Centennial Effluent Lease. Al has an agreement with Centennial Water and Sanitation District ("Centennial") that conveyed water rights in exchange for a lease of augmentation water In a December 1996 agreement, Al conveyed its ownership of shares in the Nevada Ditch Company to Centennial in exchange for 30 acre-feet of consumable effluent No explicit date of termination is set in the agreement The rate of delivery for the 30 acre-feet cannot exceed 5 cfs This rate allows Al to claim the total amount in a single month Centennial agreed to deliver the water, at its discretion, at one of the following points the mouth of Little Dry Creek, Plum Creek at the point where water from Mclellan Reservoir can be discharged by pipeline into the South Platte River, Centennial's Marcy Gulch Wastewater Treatment Plant, or by not requiring augmentation water from Al sources located above the Titan Road Gage located on Plum Creek The mouth of Little Dry Creek was used for calculating transit loss for the Centennial water The mouth is in Section 33, T 4S, R68W, approximately 2,350 feet from the South section line and 1,650 feet from the East section line 4 Historic Use of 1.038 Shares in the Brighton Ditch. Al currently leases these shares from the City of Westminster Collectively, the shares provide approximately 170 88 acre-feet per year of consumptive use credit based on dry -year yields 5 City of Thornton Lease. In exchange for three shares in the Colorado Agricultural Ditch Company, the City of Thornton has provided Al a perpetual lease of fully consumable water from the Metro Wastewater Treatment Plant to be delivered at a rate of 0 035 cfs daily from November 1st through March 31st This totals 10 53 acre-feet for the calendar year (5) The Operator/Applicant shall affirmatively state that the Operator/Appl►cant has acquired (or has applied for) a National Pollutant Discharge Elimination System (NPDES) permit from the Water Quality Control Division at the Colorado Department of Health, if necessary Al will apply for an NPDES permit prior to mining or dewatering the site Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application Exhibit G - 5 Potential Mining Impacts Tucson South Resource Groundwater Modeling Study on the Hydrogeologic Effects of Mining, prepared by Tetra Tech RMC dated August 2004 was submitted as a referral response to DRMS August 3, 2004 The study is on record with the original application and attached herein for reference A groundwater monitoring and mitigation plan was submitted to the Division as part of an adequacy response to Mr Larry Oehler dated November 22, 2004 (in pages 17 -19) The plan was reviewed and approved by the Division as part of the original permit for the site A copy of the approved Groundwater Monitoring and Mitigation Plan is described below The hydrogeologic conditions have changed since the 2004 report However, many of the changed conditions were considered in the 2004 model The Challenger Pit north of the West Area has been reclaimed as a lined storage reservoir The triangle -shaped parcel north of the East Area has been backfilled with fines The Greenhouses in the northeast corner of the West Area and the small property located entirely within the East Area are now owned by the City of Aurora and will be mined and reclaimed as part of the water storage reservoir The 2004 report presented eight hydrogeologic scenarios that address the vanous conditions and associated groundwater impacts of the for the life of Tucson South Mine Scenario 6 described on pages 9 and 10, illustrated on Figures 9 and 10, represent the current conditions with two exceptions 1 The wells at the Greenhouse property, now owned by Aurora, will be removed during mining, and 2 A previously permitted area located south of Highway 7 will not be mined (in the groundwater model this area was assumed to be wet mined The net results are likely minimal) The changes due to the Aurora property and the absence of mining of the South cell do not have a material impact on the model simulations The model indicates that after installation of the slurry wall, groundwater will mound up to approximately six feet along the western and southern edges of the West Area Given the rise in groundwater level west of the slurry wall, the mining operations will not increase seepage from the Brighton or Brantner ditches Similarly, the model indicates that there will be minimal rise in groundwater level south of the East Area This is due to the proximity of the South Platte River As mentioned above, Todd Creek Farms Metropolitan District #1 (Todd Creek) operates several water supply wells between the South Platte River and the slurry wall of the East Mine Area Todd Creek is aware of the future slurry wall and has an agreement with Al acknowledging the construction of the slurry wall and potential impacts to well yields Groundwater flows from south-southwest to north-northeast, roughly parallel to the South Platte River Consequently, there will be very little if any "shadow effect" (decline in groundwater level) in the Morgan Smith Natural Area The proximity of the River also minimizes the impacts of groundwater levels in the Morgan Smith Natural Area The modeling (Scenario 6, Figures 9 and 10) indicates there will be a shadow effect north of the mine in the narrow strip of unmined alluvial aquifer beneath Tucson Street Aggregate lndustnes — Tucson South Amendment — MLRB 112 Permit Application Exhibit G - 6 The drawdown estimated by the model assumes the wells were pumping at the Aurora property Greenhouse and one domestic well north of the mine Given that the greenhouse wells will not be pumping, the drawdown will likely be less than the of six to eight feet estimated by the model There is one remaining domestic alluvial water well in this strip of land Potential impacts to the well will be addressed by the Ground Water Mitigation Plan Groundwater Mitigation Plan Groundwater monitoring and evaluation of potential mining or reclamation impacts shall be conducted as part of the Groundwater Monitoring and Mitigation Plan The Monitoring Plan was reviewed and approved by the Division with the original permit and will be used during mining and reclamation activities Historic and current water level measurements in the monitoring wells included as part of this exhibit The Monitoring Plan is outlined below It is possible that the well north of the site may be impacted by shadowing effects of the slurry wall If the wells fail to perform at historic rates, Al will make investigations into the cause If the cause can be traced to the mine and slurry wall, Al will make efforts to improve the wells either by several alternatives including discharging water near the well, developing the well to remove scales and plugs, deepening the well, and/or constructing cisterns and delivering potable water to the cisterns for the duration of the impacts As indicated above Al may improve the existing wells rather than continue to haul water for an extended period In any event Al will provide potable water to the well owner Al is committed to installing an underdrain system to minimize disturbances to the prevailing hydrologic balance of the ground water regime near the mine Groundwater modeling indicated mounding up to approximately six feet will likely occur along the west and south west margins of the West Mine Area The design plans are attached to this exhibit The drain system will consist of two sections, South Side Drain and a West drain that conveys water along the north side of the West Mine Area Each drain has a "receiving" section and a "discharging" section In the "receiving' sections the drain will be installed at approximately the pre -mining ground water level As the mound builds it will flow into the drainpipe In non -mounding areas the "discharging "sections the drainpipe will be at or approximately one foot above the premining ground water levels In the areas of the ground water mound the ground water will flow into the drain then flow down gradient through the drainpipe and discharge back to the ground water The entire length of the drainpipe will be perforated This design concept has been utilized at the Aurora Challenger Pit Just north of the West Mine Area To establish a baseline, Al installed 17 monitoring wells at the mining site in late 2003 The frequency of water level monitoring was approximately monthly from December 2003 to July 2005 After July 2005, monitonng continued quarterly through 2017 The monitoring frequency increased to monthly in January 2018 Monitoring in the wells will continue on a monthly basis for the life of the mine and for one year after mining ends (Note MW -11 was removed during Todd Creek Metropolitan District's construction in 2017 and MW -2 south of the mine can no longer be found) MW -2 was I replaced with a Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application ExhibitG-7 new well in roughly the same location in 2018 MW -1 1 will not be reinstalled as the area of the well is adjacent to the river and Todd Creek has monitoring wells that they monitor as part of their alluvial wellfield For the wells around the East and West Mine areas, monthly water monitoring would continue to be appropriate If sufficient data is collected during the life of the mining operation, and a demonstration can be made that impacts to the groundwater system have been minimized, Al can Apply to the Division would consider approval of a Technical Revision to revise the water level monitoring frequency at a later date The Monitoring Plan will now consist of 16 monitoring wells Monitoring data will be used to identify potential changes in alluvial groundwater flow or elevation associated with mining and reclamation activities Baseline data collected from the monitoring program will provide a range of relative water levels associated with pre -mining groundwater conditions Experience at other sand and gravel mine sites in similar geologic settings shows that groundwater levels tend to fluctuate between two to four feet each year; levels are highest in the summer and lowest in the winter and early spring Al will meet with the nearby well owners and enter into a monitoring and mitigation agreement with them The details of the Mitigation Plan are provided below • If, during mining, the relative seasonal groundwater elevation at any of the domestic wells or monitoring wells differs from the baseline conditions by more than two feet, and the condition was not observed during baseline monitoring, or if Aggregate Industries receives a complaint from any well owner within 600 feet from the site boundary, then Aggregate Industnes will notify the DRMS and then evaluate the cause and take action within 30 days • After the DRMS has been notified Aggregate Industries will review the available data and information and submit a report to the DRMS within 30 days The evaluation will include discussions with any well owner who has contacted Aggregate Industries regarding a concern, and a review of baseline data from the well and vicinity to evaluate potential changes due to seasonal variations, climate, mining, or other factors The report will identify the extent of potential or actual impacts associated with the groundwater changes If the extent of groundwater changes due to mining or reclamation activities is determined to be a significant factor creating potential or actual adverse impacts, the mining -associated impacts will be addressed to the satisfaction of the DRMS Aggregate Industries will begin to implement one or more mitigation measures • Mitigation measures may include, but are not limited to • Cleaning a well to improve efficiency • Providing an alternative source of water or purchasing additional water to support historic well use water quantity and quality If needed, water quality parameters will be checked in affected wells to ensure alternative sources support the historic use • Modifying a well to operate under lower groundwater conditions This could include deepening existing wells or lowering the pumps All work would be done at Aggregate Industries' expense except for replacing equipment that was non- functional prior to mining • If existing wells cannot be retrofitted or repaired, replacing the impacted well with a new replacement well Aggregate Industries — Tucson South Amendment— MLRB 112 Permit Application Exhibit G - 8 • Providing flood irrigation to address concerns over impacts to sub -irrigated lands adjacent to the site • Al agrees to provide the water level data collected from monitoring well sampling to the DRMS with the annual report for the site • If a groundwater mitigation action is required, Aggregate Industries will notify the DRMS of the condition, action taken and result A complete well inventory "Well Inventory, Tucson South/Haake, Aggregate Site near Brighton Colorado dated March 13, 2004" was submitted to the Division with Exhibit G of the original application for this site The information is on record at the Division Since that time Aggregate Industries has obtained the required well permit for this property Aggregate Industries, through the SEQ well permit process, gave notice to well owners within 600 feet of the mining boundary The potentially impacted well owners entered into agreements with Aggregate Industries for protection for the senior vested water rights Many of these wells were near a previously permitted unlined cell south of Highway 7 This unlined cell was removed from the permit with a Technical Revision Impacts to these wells is now considered negligible due to the construction of the slurry wall prior to mining Potential Reclamation Impacts Impacts due to mine dewatenng are not anticipated due to the presence of the slurry wall constructed prior to mining of the East and West Areas Once mining and reclamation are complete and dewatenng pumps are turned off, potential impacts to surrounding wells from mine dewatenng will cease Reclamation Impact Mitigation Plan Although impacts and damages are not anticipated, it is the intent of the operator and property owners to operate responsibly and to mitigate damage to wells or structures that is directly attributable to the mining and reclamation of the Tucson South Resource site If mine or slurry wall reclamation creates injury to surrounding properties, the applicant will take all necessary actions to remedy the injury The approved well permit addresses potential impacts to wells within 600 feet of the Permit Boundary Additionally, if it is determined that mine reclamation creates mounding impacts to surrounding structures or water resources, the applicant will take appropriate corrective action Impacts would trigger mitigation measures that may include, but are not limited to • Installing surface or underground drainage systems to transport groundwater from mounding areas to shadowing areas • Diverting surface water flows to recharge ponds in shadowing areas Water Quality Mining and reclamation operations shall comply with the Colorado Department of Public Health and Environment National Pollution Discharge Elimination System (NPDES) regulations A Colorado Discharge Permitting System (CDPS) permit for stormwater management and discharge flows to protect surface water quality on and off the Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application Exhibit G - 9 proposed permit area from mining and reclamation activities will be obtained The permit includes the continued updating and implementation of a site Stormwater Management Plan designed to prevent the contact and transport of potential contaminants to surface waters by stormwater flows The depth to groundwater fluctuates by a couple of feet depending on the season, but averages about 10 feet below ground surface Due to the absence of large quantities of potential pollutants on site (no on -site processing or concrete or asphalt production), the mining and reclamation operations are not likely to affect groundwater quality on or off the site As stated above, mining and reclamation activities shall operate under a CDPS permit and Stormwater Management Plan The plan provides for regular inspections of potential contaminant areas such as mobile equipment and fuel or lubncant storage locations Inspections and best management practices are incorporated into the plan to protect both surface and groundwater quality Aggregate Industries — Tucson South Amendment — MLRB 112 Permit Application Exhibit G -10 COLORADO Division of Water Resources Department

Introduction Aggregate Industries (Al) is proposing to mine sand and gravel at the Tucson South Mine Project (Project) in Adams County, Colorado. The purpose of this report is to (1) provide a summary of local, state, and federal regulations that protect biological resources in Adams County; (2) document findings of the biological resources desktop analysis and field survey; and (3) provide recommendations for management of biological resources, including measures to avoid, minimize. or mitigate impacts, where necessary and practicable. 1.1 Project Description and Location The Project is located west of Brighton, Colorado, at the intersection of Tucson Road and Colorado Highway 7 in Sections 1 and 12 of Township 1 South, Range 67 West in Adams County. The Project area is divided by roads and parcel boundaries and is shown in Figures 1-4, attached. The total Project area is approximately 258 acres. Upon completion of mining, the site will be reclaimed as two below -grade water storage reservoirs and a reclaimed upland meadow. The Project will include the construction of temporary construction access roads, a slurry wall, gravel mining areas, and equipment storage areas. The Project is currently in the design phase and the final location of the Project features have not yet been defined. Therefore, for planning purposes, all of the Project area was evaluated for the presence of biological resources. The Project is expected to go through a review process by the U.S. Army Corps of Engineers (USAGE): U.S. Fish and Wildlife Service (USFWS); Colorado Department of Public Health and Environment; Colorado Office of Archaeology and Historic Preservation; Colorado Department of Transportation; Colorado Parks and Wildlife (CPW); Colorado Division of Mining and Reclamation Safety (DRMS), and Adams County. Construction of the Project would begin after issuance of all necessary permits, which is currently anticipated as summer 2019. The Project would be developed over time and would operate indefinitely after the City of Aurora takes control of the site and operates the two reservoirs. A biological resources inventory and wetland delineations for the Project were performed on July 6 and 7, 2017. The results of the delineation are included in the Project Wetland Delineation Report (Tetra Tech 2019) and are not included herein. Due to layout changes since fieldwork was completed, the northernmost parcel has not been field surveyed for biological resources. Desktop analysis has been completed for the northernmost parcel. Because this parcel is part of a previously permitted and reviewed project and it is heavily disturbed, there are no anticipated additional impacts to biological resources at this location. 1.2 Regulatory Setting Several biological resources within the Project are protected by federal and state laws. The following subsections briefly describe these regulations and permitting processes where applicable. Tucson South Sand and Gravel Mine Brighton, Colorado 1 2019 Biological Resources Inventory Report 1.2.1 Special Status Species The Endangered Species Act (ESA) and its implementing regulations in Title 50 of the Code of Federal Regulations (CFR) Section 17 prohibit the take of any fish or wildlife species that is federally listed as threatened or endangered without prior approval pursuant to either Section 7 or Section 10 of the ESA. The USFWS is responsible for the implementation of the ESA. Section 3 of the ESA defines "take" as "to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect or to attempt to engage in any such conduct" (16 United States Code [USC] § 1532 (19)). Harm, in this case, means an act that actually kills or injures a federally listed wildlife species and "may include significant habitat modification or degradation where it actually kills or injures wildlife by significantly impairing essential behavioral patterns, including breeding, feeding or sheltering." To harass means to perform "an intentional or negligent act or omission which creates the likelihood of injury to wildlife by annoying it to such an extent as to significantly disrupt normal behavioral patterns which include, but are not limited to, breeding, feeding or sheltering" (50 CFR §17.3). In addition, Section 9 of the ESA details generally prohibited acts, and Section 11 provides for both civil and criminal penalties for violators regarding species federally listed as threatened or endangered. Colorado Revised Statute (CRS) 33-2-105 states that it is unlawful to "take, possess, transport, export, process, sell or offer for sale, or ship" any species listed as threatened or endangered by CPW. According to CRS 33-1-102 "Take" means to acquire possession of wildlife; but such term shall not include the accidental wounding or killing of wildlife by a motor vehicle, vessel, or train." Activities that would trigger the need for USFWS or CPW consultation or permitting for the Project are discussed in more detail in Section 3. It is unlawful under the Migratory Bird Treaty Act (MBTA) (50 CFR § 10.13) to "pursue, hunt, take, capture or kill; attempt to take, capture or kill; possess, offer to or sell, barter, purchase, deliver or cause to be shipped, exported, imported, transported, carried, or received any migratory bird, part, nest, egg, or product." Birds protected under this act include most native birds, including their body parts (e.g., feathers), nests, and eggs. The Bald and Golden Eagle Protection Act (BGEPA) prohibits the take of Bald or Golden Eagles by any party. The BGEPA defines "take" as "to pursue, shoot, shoot at, poison, wound, kill, capture, trap, collect, destroy, molest, and disturb individuals, their nests and eggs" (16 USC 668c). "Disturb" is defined by regulation at 50 CFR 22.3 in 2007 as "to agitate or bother a Bald or Golden Eagle to a degree that causes... injury to an eagle; a decrease in productivity, or nest abandonment..." CPW recommends a set of seasonal buffers for specific nesting raptors that commonly occur in Colorado. including but not limited to Bald and Golden eagles (CPW 2008). These buffers are for active nests and range from 0.25 mile to 0.5 mile depending on the species. The associated date range for each seasonal buffer remains the same annually. 2 Tucson South Sand and Gravel Mine Brighton, Colorado 2019 Biological Resources Inventory Report 1.2.2 Noxious Weeds The state of Colorado promulgated the Colorado Noxious Weed Act (Act) in 1990 within Title 35, Article 5 5, Parts 110 through 119, in 1990 The Act initially created three lists A, B and C (CDA 2O17a) The state subsequently added a watch list The most recent update to the weed lists became effective March 31, 2017 The Act requires A -list species to be eradicated wherever detected to protect neighboring communities and the state as a whole There are 25 species on the A list The B list represents those species for which the state of Colorado and local governments will develop noxious weed management plans to stop the continued spread of these'species The B-hst contains 38 species Species-orithe C list are those species that the state will assist governing bodies manage through education, research, and biological controls The C list includes 15 species The watch list includes 24 species of weeds that are documented for advisory and educational purposes only at this time The state listed noxious weeds are provided in Table 1 Table 1 Colorado Noxious Weed List Lid' -

The Weed Office or its agent will continue to apply herbicides to a limited acreage of noxious weeds on private lands by landowner or tenant request, consistent with County policies. Where noxious weeds are still found, an enforcement process will be initiated to ensure control of the Weeds. According to the Policy, landowners in Adams County are required to manage noxious weed infestations. The policy also outlines criteria for county officials to inspect for noxious weed infestations on public and private land and identifies methods of notification to landowners if an infestation is found to occur and it requires that the notified landowner comply with the terms of the notification and the policy. If the landowner does not comply with the terms, the county may access the property and undertake the management of noxious weeds. In this case, the Policy outlines a method for the county to recover costs of management. Tucson South Sand and Gravel Mine Brighton, Colorado 5 2019 Biological Resources Inventory Report 2. Biological Resources Inventory This biological resources inventory featured two components: a desktop analysis and field survey. These two components were completed by biologists qualified to identify flora and fauna in the Front Range of Colorado. 2.1 Biological Resources Inventory Methods The following subsections describe the methods used to evaluate the presence of biological resources for the Project area. 2.1.1 Desktop Methods Each of the desktop resources listed below were used in evaluating the biological resources that are in the vicinity of the Project area: • USFWS Region 6 Information for Planning and Conservation (IPaC) search results for federal and state listed threatened and endangered species likely to occur near the Project area (Attachment 2) • USFWS Critical Habitat Map Service (USFWS 2017a) • CPW Bald Eagle Shapefile (CPW 2016a) • CPW threatened, endangered and species of concern for the state (CPW 2017) • CPW Species Profiles (CPW 2016c). • CPW Species Activity Data (CPW 2016b). • Colorado Natural Heritage Program (CNHP) Database CNHP maintains species profiles for protected species that can be used to identify species of concern within a Project area (CNHP 2015a. 2015b) • U.S. Department of Agriculture (USDA) Farm Service National Agricultural Imagery Program Aerial photography for Project location (USDA 2015) • Natural Resource Conservation Service (NRCS) Soil Survey Geographic (SSURGO) Database.

Knopf Publishing Group 2.1.2 Field Survey Methods Two biologists qualified to identify Great Plains flora, fauna, and noxious weeds conducted the field effort. The following subsections provide descriptions of survey methods used for each component of the field survey by the field team. The northernmost parcel was added after the completion of the field survey, data related to this area was completed by desktop review only. 6 Tucson South Sand and Gravel Mine Brighton, Colorado 2019 Biological Resources Inventory Report 2.1.2.1 Listed Species Habitat Suitability Assessment Field notes and digital photography were collected from within the Project area that presented suitable habitat characteristics that would support any species listed in Tables 3 and 4. 2.1.2.2 General Wildlife and Vegetation Assessment Tetra Tech biologists performed a field survey to document habitat types in the Project area. All species of wildlife and vegetation that were observed during the survey were recorded in a field logbook and photographed as practicable. Locations of certain resources, such as potential black -tailed prairie dog colonies in the Project area, were mapped using a generic GPS software loaded on the field tablet computer. 2.1.2.3 Avian Survey Methods Tetra Tech biologists surveyed the Project area for raptor nests and trees that could support raptor nests The largest buffer for active raptor nests recommended by CPW is 0.5 mile for the Bald Eagle, so only trees within 0.5 mile buffer of the Project area were surveyed for nests. The raptor nest survey was completed during full leaf -out of deciduous trees in the Project area, so trees with the potential to support nests were observed with field binoculars to search for nests to the greatest extent possible. CPW defines an active nest as any nest that is "frequented or occupied by a raptor during the breeding season or which has been active in any of the five previous breeding seasons" (CPW 2008). Biologists also documented suitable habitat and sightings of individual bird species protected by the MBTA in the Project area 2.1.2.4 Noxious Weed Inventory An informal survey for state listed noxious weeds was conducted incidentally during the general wildlife and vegetation assessment. This effort was not intended to be, and should not be considered, an extensive survey of the entire Project area. 2.2 Biological Resources Inventory Results and Discussion The following sections describe the results of the biological resources assessment completed for the Project area. 2.2.1 Desktop Results 2.2.1.1 Ecoregional Setting The Project is completely situated in the High Plains Level III Ecoregion. The High Plains Ecoregion includes four Level IV ecoregions. The Project area lies within the Flat to Rolling Plains (25d) Level IV ecoregion (Chapman et at 2001). This ecoregion is characterized by moderate topological relief, silty and sandy soils, shortgrass prairie vegetation, and intermittent streams with few perennial streams. This ecoregion is known to have small scattered depressional "playa" wetlands and dense oil and gas production. Elevation in the Project area is between 4,900 and 5,000 feet above sea level.

(2009) 6 Source: Nico et at (2017) 7 Source: Fitzgerald et at (1994) 8 Source: USFWS (2010) 2.2.1.4.1 Burrowing Owl Burrowing owls (ST), have suitable habitat in active and remnant black -tailed prairie dog colonies that intersect the Project area. Only one of three potential black -tailed prairie dog colonies were documented to be active in the Project area; however, burrows that could be used as burrowing owl habitat were documented in each mapped potential black -tailed prairie dog colony. Pre -construction surveys for burrowing owls according to CPW-recommended survey protocol would be conducted in these locations if construction occurs during the burrowing owl breeding season (March 15 —October 31). If nesting owls are observed, the nesting location will be documented, and Al will notify the DRMS. Al will implement the CPW-recommended 150 -foot non -encroachment buffer from active burrows. 2.2.1.4.2 Plains Minnow, Suckermouth Minnow, and Brassy Minnow Three fish species, plains minnow (SE), suckermouth minnow (SE), and brassy minnow (ST) have the potential to occur in perennial and intermittent waters intersected by the Project. Impacts to perennial and intermittent streams (Brighton Ditch, Brantner Ditch, and the Brighton Return) in the Project area will be avoided, and stream flows will not be altered. No impacts to these species are expected. 2.2.1.4.3 River Otter River otters (ST) prefer riparian habitats along perennial river systems and are known to occur along the South Platte River. River otters use beaver dens and lodges, brush piles, and muskrat dens in secluded areas for natal dens, rearing young throughout the spring and summer months (Fitzgerald et al. 1994). The Project would avoid direct impacts to the river otter and impacts to potential river otter breeding habitat along the South Platte River and its associated riparian area including potential natal dens. No impacts to the South Platte River, the river otter, or its habitat is anticipated. 2.2.1.5 Migratory Birds CPW shapefiles were consulted to identify any known potential Bald Eagle or Osprey nests located in or near the Project area. The closest documented Bald Eagle nest is located approximately 0.8 mile away from the Project area (CPW 201c) Table 5 lists 24 species of migratory birds that should be considered as part of an effects analysis for this Project area according to IPaC output (Attachment 2) Tucson South Sand and Gravel Mine —Brighton, Colorado 13 2019 Biological Resources Inventory Report Table 5 USFWS IPaC-Identified Migratory Birds Likely to Occur in the Project area Common Name - Scientific Name Season American Bittern Botaurus lentiginosus Breeding Bald Eagle Hahaeetus leucocephalus Year-round Black Rosy -finch Leucosfscfe atrata Year-round Brewers Sparrow Sp►zella brewen Breeding Burrowing Owl Athene cuniculana Breeding Dickcissel Sp►za Amencana Breeding Ferruginous Hawk Buteo regahs Year-round Golden Eagle Aquila chrysaetos Year-round Lark Bunting Calamosprza melanocorys Breeding Lewis's Woodpecker Melanerpes lewis Breeding Loggerhead Shnke Lanus ludovicianus Breeding Long -billed Curlew Numenius amencanus Breeding Mountain Plover Charadnus montanus Breeding Peregnne Falcon Falco peregnnus Breeding Praine Falcon Falco mexicanus Year-round Red-headed Woodpecker Melanerpes erythrocephalus Breeding Rufous Hummingbird Selasphorus rufus Migrating Sage Thrasher 0►eoscoptes montanus Breeding Short -eared Owl Asio tlammeus Wintenng Swainson's Hawk Buteo swainson► Breeding Virginia's Warbler Vermivora v►rg►niae Breeding Western Grebe Aechmophorus occ►dental►s Breeding Williamson's Sapsucker Sphyrapicus fhryro►des Breeding Willow Flycatcher Empidonax fraill►i Breeding 2.2.1.6 Land Cover The land cover for the Project area was determined through a desktop analysis of the National Land Cover Database (Fry et al 2011) The Project area lies within cover classes identified by the NLCD as cultivated cropland, hay/pasture, herbaceous, grasslands, woody and herbaceous wetlands, and developed and barren (Figure 2) 2.2.2 Field Survey Results The field survey was completed on July 6 and 7, 2017 The following sections describe the results of this survey effort 2.2.2.1 General Wildlife Resources Biologists documented four of the nine general wildlife species identified as having potential to occur by CPW (Table 2) in the Project area including four black -tailed prairie dogs, one Great Blue Heron, five White Pelicans, and three wild turkeys In addition, an eastern cottontail rabbit (Sylwlagus flondanus) was observed Other avian species observed perched or flying in the Project area included Mallard (Anas 14 Tucson South Sand and Gravel Mine—Bnghton, Colorado 2019 Biological Resources Inventory Report platyrhynchos), American Crow (Corvus brachyrhynchos), Black -billed Magpies (Picea hudsonia), Red- wing Blackbird (Agelaius phoeniceus), Mourning Dove (Zenaida macroura). and Western Tanager, (Piranga ludoviciana). All of the bird species observed in the Project area are protected under the MBTA (USFWS 2013). The mammals identified by CPW as having potential to occur in the Project area or identified during the survey are not restricted to the site and commonly have large home ranges. Rodent species are known to hibernate or become dormant for portions of the winter. Avian species may be migrants or residents of the Project area. Activity in the Project area would temporarily displace wildlife and reduce available habitat for animals currently living in the Project area during active operations. Vegetation and preparation of work sites poses the greatest disruption to wildlife in the Project area. During vegetation clearing, a majority of individuals would move away from construction activities given the disruptive nature of these activities. Some individuals would either attempt to hide within the path of disturbance (e.g., small mammals or reptiles may attempt to burrow underground or remain motionless within the vegetation during clearing) or would be unable to relocate away from the disturbed area The Project is not expected to have significant impacts on migratory routes for avian resources. The Project is not within any known major avian migration corridors or stop -over sites, and would not impede flight for avian resources or prohibit stop -over in nearby areas. The Project may cause a minor temporary displacement in local food resources for carnivores as some small mammals and insects would be displaced or during construction. A slight decrease in available food for herbivores may also occur due to vegetation clearing. Some species such as birds or ungulates would continue to use the Project area while project activities are underway. Noise and dust emissions during construction would also cause some wildlife to temporarily leave the Project area during construction No long-term impacts to wildlife species are expected by the Project. Permanent reclamation of the site will be reclaimed as two below -grade water storage reservoirs and a reclaimed upland meadow in the Project area. Native vegetation will be seeded and planted which will support wildlife species. Wildlife would be allowed to return to the Project area following mining operations. Overall wildlife and vegetation habitat is expected to improve compared to the habitat that currently exists. Available food for both herbivores and carnivores is expected to increase when the Project is completed because wildlife habitat and vegetation habitat is expected to improve. 2.2.2.2 Raptor Nest Survey Results During the field surveys, two potential raptor nests were observed in the Project area (TM-UNK-01, TM- UNK-02) (Figure 1). The nests were not observed to be active during surveys. In addition, two Red-tailed Hawks were identified on several occasions flying over the Project area. Several large stands of deciduous trees with the potential to support raptor nests were observed throughout the Project area and within a 0.5 mile buffer of the Project area. The east side of the Project area in the riparian corridor along the South Platte River was noted to have a relatively high abundance of potential nesting sites Tucson South Sand and Gravel Mine —Brighton, Colorado 15 2019 Biological Resources Inventory Report 2.2.2.3 Listed Species —Habitat Suitability Assessment Results All federally listed species in the USFWS IPaC summary were determined to be unlikely to occur in the desktop analysis (Table 2) Field surveys confirmed the information provided in Table 3 Desktop analysis determined that there was potential for five state -listed species to occur or to have suitable habitat in the Project area These five species Included burrowing owl (ST), brassy minnow (ST), plains minnow (SE), suckermouth minnow (SE), and river otter (ST) The field survey effort documented suitable habitat for all five of the state listed species 2.2.2.4 General Vegetation Results The field survey identified 47 species of native and introduced plants within the Project area These plant species are listed in Table 6 Table 6 Vegetation Observed in the Project Area, July 6 and 7, 2017 ` Common Name Scientific Name Notes Russian knapweed Acroptilon repens Listed noxious weed Crested wheatgrass Agropyron cnstatum Introduced herbaceous species Desert madwort Alyssum desertonim Introduced herbaceous species Common ragweed Ambrosia a►temisi►fola Native herbaceous species Perennial ragweed Ambrosia psdostachya Native herbaceous species Pncklypoppy Argemone h►spida Native herbaceous species Smooth brome Bromus inermis Introduced herbaceous species Downy brome Bromus tectorum Listed noxious weed Plumeless thistle Carduus acanthoides Listed Noxious weed Musk thistle Carduus nutans Listed NOXIOUS weed Diffuse knapweed Centaurea diffusa Listed noxious weed Lambs quarters Chenopodium album Introduced herbaceous species Oakleaf goosefoot Chenopodium glaucum Introduced herbaceous species Canada thistle Cirsium arvense Listed noxious weed Field bindweed Convolvulus arvensis Listed noxious weed Horseweed Conyza canadensis Introduced herbaceous species Barnyard grass Ech►nochola crus-gall Introduced grass Russian olive Elaegnus angushfolia Listed noxious weed Slender wheatgrass Elymus trachycaulus Native herbaceous species Annual wheatgrass Eremopyrum tnticeum Introduced grass Leafy spurge Euphorbia escula Listed noxious weed Broomweed Gutierrezia sarothrae Native shrub Hairy false goldeneaster Heterotheca villosa Native herbaceous species Foxtail barley Hordeumtubatum Native herbaceous species Baltic rush Juncus balticus Native herbaceous species Kochia Kochia scopana Native herbaceous species Pnckly lettuce Lactuca semola Introduced herbaceous species Clasping pepperweed Lepedium perfol►atum Introduced herbaceous species 16 Tucson South Sand and Gravel Mine—Bnghton, Colorado 2019 Biological Resources Inventory Report Table 6: Vegetation Observed in the Project Area, July 6 and 7, 2017 Common Name Scientific Name Notes Russian knapweed Acroptilon repens Listed noxious weed Whitetop Lepidum draba Introduced herbaceous species White horehound Marrubium vulgare Introduced herbaceous species Scotch cottonthistle Onopordum acanthium Introduced herbaceous species Reed canarygrass Phalaris arundinaceae Introduced herbaceous species Annual rabbitsfoot grass Polypogon monspeliensis Introduced herbaceous species Plains cottonwood Populus deltoides ssp.

Conclusions This biological resources assessment evaluated major categories of resources including special status species, general wildlife and vegetation, and state listed noxious weeds The special status species included assessment of federal and state listed species, raptors, and migratory birds 3.1 Federal and State Listed Species No federal listed species were determined to have suitable habitat in the Project area Five state -listed species were determined to have suitable habitat and potential to occur within the Project area including burrowing owl (ST), brassy minnow (ST), plains minnow (SE), suckermouth minnow (SE), and river otter (ST) These species are protected against take under CRS 33-2-105 Species -specific mitigation measures for each species are described in Section 2 2 1 4 and are summarized in Table 10 below All state threatened and state endangered species within the Project area will be protected against take under CRS 33-2-105 Table 10 Mitigation Measures for State -Listed Species With Potential To Occur in the Project Area "-- = _- Common Name -', Scientific Name , -- ' (Release) , �� K ,', - _,Status - -' 'Mitigation Measures - , ,- _ - R - ' , _ '- _ _ I �n� r '� � �� Burrowing Owl Athene cuniculana ST Pre -construction surveys for burrowing owls according to CPW- recommended survey protocol would be conducted in these locations if construction occurs dunng the burrowing owl breeding season (March Tucson South Sand and Gravel Mine —Brighton, Colorado 19 2019 Biological Resources Inventory Report Table 10: Mitigation Measures for State -Listed Species With Potential To Occur in the Project Area Common Name Scientific (Release) Name Status Mitigation Measures location recommended 15 Mining, until nesting —October a qualified location will Reclamation, 31). be 150 documented. biologist 150 If nesting -foot and feet non Safety. can outside burrowing -encroachment and confirm the Al Al will owls will owls Project notify implement are have buffer area. observed, the from migrated Colorado the active CPW- the or nesting Division burrows moved of Brassy minnow Hybognathus hankinsoni ST intersected These Project have area potential by the will be Project. avoided. to occur Perennial No in impacts perennial and and intermittent to these intermittent species streams waters in are expected. the Plains Minnow Hybognathus placitus SE Suckermouth Minnow Phenacobius mirabilis SE River Otter Lontra canadensis ST The potential associated No anticipated. impacts Project river riparian would to otter the avoid South breeding area including direct Platte habitat impacts River, along potential the to the river the river natal South otter, dens otter Platte or for its and the habitat impacts River river and is otter. to its 3.2 Migratory Birds Two potential raptor nests were observed in the Project area during the raptor nest survey. Neither were confirmed to be active at the time of the survey. Nest surveys will be completed prior to the first year of construction during the winter months prior to leaf -out of trees in the Project. Results of the nest surveys will be provided to the DRMS. If an active raptor nest is encountered during pre -construction surveys, Al will follow the recommendations of CPW's "Recommended Buffer Zones and Seasonal Restrictions for Colorado Raptors" (CPW 2008). Construction disturbance is not expected to affect raptors to the extent that injury, loss of productivity, or nest abandonment occurs. All migratory birds within the Project area will be protected against take under the MBTA. 3.3 Vegetation Resources The field survey identified 47 species of native and introduced plants within the Project area. Seven main cover types were observed during the field survey and are shown in Figure 3: forested riparian floodplain, mowed grassland, fallow corn field, invasive annual grassland, invasive annual/biannual forbland, and riparian/ herbaceous wetland. Shortgrass and prairie would be the dominant native ecosystem type in the Project area under natural conditions, which were not observed during the field survey. 3.4 Listed Noxious Weeds Four List B species were identified in the Project area and two List C noxious weeds were identified. No large infestations of noxious weeds were identified. Adams County has listed Russian olive and musk thistle for eradication by 2022. Downy brome, in particular, was observed in several large dense patches. Tetra Tech recommends consultation with the Adams County noxious weed coordinator to determine requirements for control of noxious weeds prior to construction. 20 Tucson South Sand and Gravel Mine Brighton, Colorado 2019 Biological Resources Inventory Report 4.

Introduction A. Purpose of This Plan The purpose of this Adams County Noxious Weed Management Plan is to provide guidelines for effectively managing designated noxious weeds, which constitute a present threat to the natural resources of lands in unincorporated Adams County. This plan implements the mandates of the Colorado Noxious Weed Act (also referred to herein as the Act) and 8CCR1206-2, revisions to the Act (also referred to herem as part of the Act). Specific management practices, directed by the Act are integrated m the County plan Educational outreach, preventive measures, and good stewardship components are also included. It is this plan's intent to incorporate those options that are the least environmentally damaging, yet practical, timely, and economically feasible. B. Enactment Authority The Colorado Noxious Weed Act (C R S §35-5.5-101, et seq) was signed into state law in 1990, amended in 1996 and revised in 2003. The Act states that certain noxious weeds pose a threat to the natural resources of Colorado. It also states that it is the duty of all persons to use integrated methods to manage noxious weeds if the same are likely to be materially damaging to the land of neighboring landowners It further directs that the Board of County Commissioners of each county in the state shall adopt a Noxious Weed Management Plan for all unincorporated land within the county. The Act directs the Board of County Commissioners to appoint a local advisory board, whose power and duties are threefold: 1. Develop recommended management cnteria and integrated weed management plans for managing designated noxious weeds; 2. Declare noxious weeds and any state noxious weeds designated by rule to be subject to integrated management; and 3 Recommend to the Board of County Commissioners that certam landowners be required to submit mtegrated weed management plans for managing designated noxious weeds on their properties. The jurisdictional area of the Adams County Board of Commissioners is all of the unincorporated lands within the County. This plan shall be referred to as the Adams County Noxious Weed Management Plan, or the County Management Plan (CMP). It was developed by the Adams County Weed Advisory Board (also referred to herein as County Advisory Board). C. Jurisdiction and Scope of Plan This plan shall apply to all subject lands within Adams County It does not preclude the County from entering into intergovernmental agreements with other governmental entities towards managing noxious weeds under the Colorado Noxious Weed Act The Adams County Weed Office (reffered to herein as the Weed Office) is aware that the Federal Noxious Weed Act (1974), as amended by Section 15 (management 3 of Undesirable plants on Federal Lands (1990)), directs federal agencies to have an office or person trained to coordinate a noxious weed management program, to adequately fund the program, to implement cooperative agreements and to conduct integrated weed management. It also directs that such agencies manage on Federal lands those designated noxious weeds on Federal lands within the county. The Weed Office recognizes that a Memorandum of Agreement regarding noxious weed management was signed in Colorado in 1996 among 13 federal and state agencies with land management and natural resource protection responsibilities. D. Definitions The following definitions shall apply to terms used in this plan. 1. "Act": the Colorado Noxious Weed Act, Article 5.5 of Title 35, C.R.S § 35-5 5-101, et seq., as amended. 2. "CMP": the Adams County Noxious Weed Management Plan, and as further defined under "Management Plan" below. 3. "County": the unincorporated areas of the County of Adams (Adams County) which are owned and managed by Adams County. 4. "County Advisory Board": the individuals appointed by the Board of County Commissioners, Adams County, to serve on the Adams County Weed Advisory Board and advise the County on matters of management of noxious weeds. 5. "IMP": an individual noxious weed management plan, as further defined under "Management Plan" below. 6. "Infestation": to have overrun or inhabit, so as to be harmful or bothersome. 7. "Integrated Management": the planning and implementation of a coordinated program utilizmg a variety of methods for managing noxious weeds, the purpose of which is to achieve desirable plant communities Such methods may include but are not limited to education, preventive measures, good stewardship, and the following techniques: (a) "Biological management": which means the use of an organism to disrupt the growth of noxious weeds. (b) "Chemical management": which means the use of herbicides or plant growth regulators to disrupt the growth of noxious weeds. (c) "Cultural management": which means methodologies or management practices that favor the growth of desirable plants over noxious weeds, including maintaining an optimum fertility and plant moisture status in an area, planting at optimum density and spatial arrangement in an area and planting species most suited to an area (d) " Mechanical management": which means methodologies or management practices that physically disrupt plant growth, including tilling, mowing, burning, flooding, mulching, hand -pulling, hoeing and grazing. 8. "Landowner": any owner of record of federal, tribal, state, county, mumcipal or pnvate land 9. "Local advisory board": The Adams County Noxious Weed Management Advisory Board are those individuals appointed by the Adams County Board of Commissioners to advise on matters of noxious weed management 10. "Local governing body": The Adams County Board of Commissions. 11. "Local Noxious Weed": any plant of local importance which has been declared a noxious weed by the Commissioners 12. "Management": any activity that prevents a plant from establishing, reproducing, or dispersing itself. 13. "Management objective": means the specific, desired result of integrated management efforts and includes - (a) "Eradication": which means reducing the reproductive success of a noxious weed species or specified noxious weed population in largely un-infested regions to zero and permanently eliminating the species or population within a specified period of time. Once all specified weed populations are eliminated or prevented from reproducing, intensive efforts continue until the existing seed bank is exhausted. (b) "Containment": which means maintaining an intensively managed buffer zone that separates infested regions, where suppression activities prevail, from largely un-infested regions, where eradication activities prevail. (c) "Suppression": which means reducing the vigor of noxious weed populations within an infested region, decreasing the propensity of noxious weed species to spread to surrounding lands, and mitigating the negative effects of noxious weed populations on infested lands. Suppression efforts may employ a wide variety of integrated management techniques (d) "Restoration": which means the removal of noxious weed species and reestablishment of desirable plant communities on lands of significant environmental or agricultural value m order to help restore or maintain said value. 14. "Management Plan": a noxious weed management plan developed by any person, or the Local Advisory Board, using integrated management The "County Management Plan" (CMP, or this plan) shall refer to the integrated management plan adopted by the County Advisory Board for the subject lands. An "Individual Management Plan" (IMP) shall refer to an integrated management plan for a specific property or group of properties as submitted by a landowner(s), and approved by the County Advisory Board, or its designated agent. 15. "Noxious Weed": an alien plant or parts of an alien plant that has been designated by rule as being noxious or has been declared a noxious weed by the Colorado Agriculture Commissioner, or Adams County Board of Commissioners, and meets one or more of the following additional cntena (a) Aggressively invades or is detrimental to economic crops or native plant communities; (b) Is poisonous to livestock; 5 (c) Is a carrier of detrimental insects, diseases, or parasites, The direct or indirect effect of the presence of this plant is detrimental to the environmentally sound management of natural or agricultural ecosystems. 16.

State -Listed Noxious Weeds State noxious weed list and rules and regulations under the Act are developed by the Commissioner of the Colorado Department of Agriculture (CDA) The most recent changes made to the Act pertain to the classification of noxious weeds into one of several categories. The categories include the A, B, and C Lists. List k "Rare noxious weed species that are subject to eradication wherever detected statewide m order to protect neighboring lands and the state as a whole". The Weed Office will momtor and comply with any amendments to the rules and regulations. Any weeds designated by the Colorado Noxious Weed Act for eradication containment, or suppression are automatically included in the Adams County Weed Management Plan. The Act is subject to continuous revision and the Adams County Weed Plan will be updated no less than every three years.

County Designations The law defines noxious weeds as plant species that are not indigenous (native) to the state of Colorado and meet at least one of several criteria regarding their negative impacts upon crops, native plant communities, livestock, and the management of natural or agricultural systems. This definition applies to species listed by both state and local governing bodies. A local governing body may also adopt eradication, containment, or suppression standards that are more stringent than the standards adopted by the Colorado Department of Agriculture Commissioner. Any species subject to designation require a public hearing before the County Commissioners prior to being granted noxious status All impacted landowners must be notified. 1. County Designated B List species. Japanese knotweed, (Polygonum cupidatum) Common Reed, (Phragmites austrahs) III. Objectives and Goals A. Objectives The objectives of this CMP are to: 1. Develop and implement integrated management programs for noxious weeds on County owned open space properties, easements and Rights -of -way. 2. Continue and improve educational programs that will effectively communicate noxious weed impacts and management methods 3. Offer to provide landowners/occupants with technical support in establishing their I.M.Ps. 4. Work with state and federal agencies towards establishing effective integrated noxious weed management programs on their properties. 5. Outline processes for enforcing control of noxious weeds on private and public properties. 6. Select control methods according to 8 CCR1206-2 for A, B and C list species and for non - listed weeds select control methods that are practical, economically reasonable and least environmentally damaging. 8 B. Goals 1. Educate landowners/occupants and county employees on weed awareness, prevention, identification, containment and eradication strategies consistent with state statutes 2. Concentrate on early detection and control of new noxious weed infestations. 3. Maintain a current noxious weed infestation map. 4. Develop and coordinate with Natural Resource Analyst, integrated weed management plans for open space properties, and easements and evaluate results annually. 5. Establish contact with landowners/occupants who have noxious weed infestations. 6 Protect native ecosystems Burn degradation by noxious weed infestations 7. Work pro -actively with federal, state and local agencies, to manage noxious weeds on a regional scale. 8. Monitor county right-of-ways for new invaders and to evaluate right of way maintenance needs. 9. Maintain application, records and training requirements for seasonal staff IV. Plan Components A. Prevention Measures Preventive control involves use of measures that will prevent the introduction or establishment of noxious weeds into areas not currently infested with noxious weeds. Prevention also includes the eradication of small, new infestations These measures usually are the most practical and cost-effective means of integrated weed management. Preventive measures that have applicability to the subject lands are. 1) using weed -free seed and mulch, 2) promoting the Colorado Weed Free Hay and Forage program, 3) priontrzmg weed management areas along routes of entry and dispersal, and 4) monitoring noxious weed infestations in bordering counties. With regard to measure number 3, the Weed Inspector and Public Works Department will control noxious weeds on County rights -of -way from May through October. Public education programs will emphasize weed infestation prevention Sites found to have small infestations of a new, uncommon noxious weed will be given high prionty for management purposes. A coordinated control effort with private landowners will be organized, where applicable. The Colorado Department of Transportation, railroad and ditch companies, and the Rocky Mountain Arsenal will be contacted. They will be encouraged to prevent noxious weed infestations, and to manage and prevent the spread of existing infestations. B. Educational Programs 1. Education of the public is a key component of integrated weed management Emphasis will be made on continuing and expanding educational noxious weed programs, such as the following 2 Timely media articles concerned with noxious weed identification and management. Emphasis will be made of the alien origin of noxious weeds and the consequences of not managing them 3. Via the media and seminars, offer the assistance of the County Weed and Cooperative Extension offices in weed management and IMP matters. 4. Conduct landowner/occupant noxious weed management seminars or talks. 5. Distribute educational brochures and field visitor's questions at local fairs and events. 9 6. Conduct noxious weed identification, management, and awareness seminars with county parks and public works personnel. 7. Utilize Extension Fact Sheets when possible. Prepare informational brochures on integrated noxious weed management for the public. Make herbicide labels available at public and educational events. 8. Initiate and conduct test plots on integrated noxious weed management. Hold field days addressing same. 9 Provide training for seasonal applicators. C. Mapping Mapping is a valuable tool in integrated weed management. As such, the Weed Inspector will establish and maintain visual maps of past and current infestations of noxious weeds on subject land. From these, a graphic representation of weed management progress and needs will be evident. The primary goal of mapping is to record the noxious weed species present, the area infested, density of the infestation, soil types, groundwater depth, and other site factors pertinent to managing the infestation successfully. D. Intergovernmental Agreements and Contracts Intergovernmental Agreements (IGAs) and contracts are useful tools towards more effective noxious weed management among agencies and governments Through cooperation, more is understood and more is done. Towards this end, the Weed Inspector will contact certain entities concerning compliance with the Act. Contracts and IGAs will be encouraged towards cooperative efforts in managing noxious weeds. Assistance will be offered towards helping each agency developing IMPS for their lands. The following organizations will be contacted: Colorado State Department of Transportation Colorado State Department of Parks and Recreation Colorado Division of Wildlife Colorado State Land Board County municipalities Rocky Mountain Arsenal Any other organizations when applicable E. Roads Right -of -Ways (ROW) are inspected and noxious weed infestations treated on an annual basis Since roads are a pnmary source of seed spread and new invader introductions, inspections and rapid response are critical in reducing future impacts. County responsibilities are outlined in the Act. The Weed supervisor works closely with Pubhc Works and the Colorado Department of Transportation to coordinate activities and communicate in the management of noxious weeds along county ROWs. The County maintains a contract with a private applicator for weed control along state highways F. Management Plan Evaluation The goals and plan of work in this CMP will be reviewed and evaluated at the regular meetings of the County Advisory Board. Any proposed additions or changes shall be approved by the County Advisory Board and the Board before becoming final 10 The full CMP shall be reviewed and amended, as needed, at least every three years (C R.S. 35-5.5- 107(4a)) Enforcement A. Noxious Weed Management on Private Properties Cooperation from all landowners/occupants regarding timely noxious weed management will be encouraged via positive communication and education efforts. The Weed Office or its agent will continue to apply herbicides to a limited acreage of noxious weeds on private lands by landowner or tenant request, consistent with County policies. Where noxious weeds are still found, an enforcement process will be initiated to ensure control of the weeds The Adams County enforcement process is available for public review m Appendix A The process is subject to change as a result of any revisions made to the Act, or from any judicial decision that affects the process. It is desirable that the Weed Office have work priorities with regard to enforcement activities on subject lands. This is due to the size of the subject area and to the number of landowners with existing noxious weed infestations. The following list pnontizes enforcement: Complamt properties Enforcement regions as mapped by the Weed Office. Lands bordering waterways (e.g. ditches, canals, rivers, creeks) 11 APPENDICES APPENDIX A ADAMS COUNTY NOXIOUS WEED ENFORCEMENT POLICY PURSUANT TO THE COLORADO NOXIOUS WEED ACT PART 1 GENERAL PROVISIONS Section 101.

Local governing bodies and landowners with any population of any List A species or population of any List B species designated for eradication may be eligible for a compliance waiver granted by the Commissioner Eff 07/01/2007 6 2 To apply for a compliance waiver, local governing bodies or landowners must submit a written petition to the State Weed Coordinator via mail (Colorado Department of Agnculture, 700 Kipling Street, Suite 4000, Lakewood, CO 80215-8000), fax (303- 239-4125), or email (csdcomments@as state co us with °Attention noxious weed petition" in the subject line) The Department will only consider a petition for waiver during the growing season of the target weed when the extent of the problem can be properly evaluated at the site for which the petition is submitted The petition should provide specific information pertinent to the reevaluation of eradication as the appropriate management objective for a specified geographic region. Eff 07/01/2007 6 3 The Commissioner will evaluate petitions using the following cntena. Eff 07/01/2007 A. The known distnbution of the weed species in the specified geographic region; Eff 07/01/2007 B The feasibility of current control technologies to achieve eradication of the population, Eff 07/01/2007 C.

February 11, 2004 — Effective May 3, 2004 Statutory Authority These permanent rules are adopted by the Commissioner of Agriculture pursuant to his authonty under the Colorado Noxious Weed Act, § § 35-5 5-108 and 115, C R S (2003) Eff 07/01/2007 Purpose The purpose of these permanent rules is to- (1) repeal all of the existing permanent rules for the administration and enforcement of the Colorado Noxious Weed Act, § § 35-5 5-101 through 119, C R S (2003), currently published at 8 C.C R 1203-15 (including the Statement of Basis, Purpose and Statutory Authority as well as Rules 1 through 3) and, (2) replace the current permanent rules with new permanent rules which implement the Colorado Noxious Weed Act as amended by the General Assembly in its 2003 regular session Specifically, the purposes of these new permanent rules are to designate state noxious weeds, classify state noxious weeds into three categories (List A, B, and C), develop and implement state noxious weed management plans for List A noxious weed species, prescribe integrated management techniques to achieve eradication of List A species, and provide a process for granting compliance waivers to local governing bodies and landowners in order to develop and implement a coordinated, statewide effort to stop the spread of noxious weeds and mitigate their impacts to agriculture and the environment Eff 07/01/2007 Factual and Policy Issues The factual and policy issues encountered in the proposal of these permanent rules are as follows. Eff 07/01/2007 1 Several million acres of Colorado are infested with invasive non -indigenous plants that are continuing to spread to uninfested lands and increase in abundance Eff 07/01/2007 2 A number of these species, designated as state noxious weeds, aggressively invade or are detrimental to economic crops or native plant communities, are poisonous to livestock, are carners of detrimental insects, diseases, or parasites, or are detrimental, directly or indirectly, to the environmentally sound management of natural or agricultural systems Eff 07/01/2007 3. Noxious weeds are a present threat to the economic and environmental value of the lands of the state of Colorado and it is a matter of statewide importance that the governing bodies of counties and municipalities manage such weeds in a coordinated manner across the state Lack of such coordination makes weed management efforts unnecessarily costly and limits the effectiveness of public and private efforts to control such noxious weeds Eff 07/01/2007 4 A broad array of public and pnvate organizations support efforts to develop and implement a coordinated, statewide effort to stop the spread of noxious weeds Eff 07/01/2007 31 5. Classifying designated noxious weeds into specific management categones will provide a means to focus public and private resources strategically and in a cost-effective manner Eff 07/01/2007 6. By eradicating rare noxious weed species quickly (List A), these species can be prevented from establishing permanent populations in Colorado from which they will spread to harm the agncultural and environmental values of the lands of Colorado Eff 07/01/2007 7 It is important that local governing bodies and affected landowners apply integrated management techniques that will achieve the specified management objectives, particularly for eradication Some techniques are more effective than others (prescnbed) and some techniques are likely to be ineffective or contribute to the spread of the weed species (not prescribed) Prescribing integrated management techniques to achieve specified management objectives will help landowners achieve management objectives such as eradication in a timely manner while limiting environmental damage, effort, and cost Eff 07/01/2007 8 By stopping the spread of well -established species (List B), the values of uninfested lands for agnculture or the environment can be protected and the costs of land management to pnvate and public landowners can be limited or reduced Eff 07/01/2007 9. By educating the public about improved management for widespread species (List C), the harm associated with these species can be reduced and such efforts can be made more cost-effective for many citizens Eff 07/01/2007 10 To accomplish the goals associated with List A (statewide eradication) and List B (halted spread) it is necessary to develop and implement statewide plans to coordinate appropnate actions at the pnvate, local, state, and federal levels Without such plans, it will be difficult to focus public and pnvate resources strategically and in a cost-effective manner to achieve these goals Eff 07/01/2007 11 In order to provide flexibility to respond to changing circumstances with respect to the distribution of weed populations, it is important to provide the state, local governing bodies, and landowners with a process to amend the requirement to eradicate a particular noxious weed. Without such a compliance waiver process, these rules may become unnecessarily burdensome Eff 07/01/2007 12 The absence of rules to implement a coordinated statewide effort to manage noxious weeds results in increased management costs to public and pnvate interests, a reduction in the effectiveness of individual efforts, and the continued loss of agricultural and environmental values to the invasion of noxious weeds Eff 07/01/2007 7'.2o March 4, 2005 — Effective May 2, 2005 Statutory Authority These amendments to the rules are adopted by the Commissioner of Agriculture pursuant to his authonty under the Colorado Noxious Weed Act, § § 35-5 5-108 and 115, C.R S (2004) Eff 07/01/2007 Purpose The purposes of these amendments to the rules are to• (1) designate additional species of noxious weeds for inclusion in the current categones (Lists A, B, C) listed in Parts 3, 4 and 5 of the existing Rules, (2) reclassify some of the currently listed noxious weeds to different categones, (3) develop and implement new state noxious weed management plans for additional species listed for statewide 32 eradication (List A), (4) develop and implement state noxious weed management plans for selected List B species and, (5) identify priority List B species, among other possible List B species, for which the Commissioner intends to develop and implement state noxious weed management plans. Eff 07/01/2007 Factual Basis The factual and policy issues encountered in the proposal of these amendments to the rules are as follows Eff 07/01/2007 1 It is necessary to periodically adjust the state noxious weed list to address emerging plant pest threats as they become known to the state Eff 07/01/2007 2 The current rules pertaining to the administration and enforcement of the Colorado Noxious Weed Act state that the Commissioner will develop and implement state noxious weed management plans for selected List B species Eff 07/01/2007 3 State noxious weed management plans are necessary in order to coordinate appropnate actions at the private, local, state, and federal levels that will halt the continued spread of these List B species Eff 07/01/2007 4 The proposed plans have been developed in consultation with the state noxious weed advisory committee, local governments, and other interested parties Eff 07/01/2007 7.3. March 9, 2006 — Effective May 30, 2006 Statutory Authority These amendments to the rules are adopted by the Commissioner of Agnculture pursuant to his authority under the Colorado Noxious Weed Act, § § 35-5 5-108 and 115, C R S (2005) Eff 07/01/2007 Purpose The purposes of these amendments to the rules are to (1) develop and implement state noxious weed management plans for selected List B species and (2) identify pnonty List B species, among other possible List B species, for which the Commissioner intends to develop and implement state noxious weed management plans The rule will also be moved to the Conservation Services Division section of the CCR and renumbered to 8 CCR 1206-2 to reflect a reorganization in the Colorado Department of Agriculture moving the noxious weed program to this division Eff 07/01/2007 Factual Basis The factual and policy issues encountered in the proposal of these amendments to the rules are as follows Eff 07/01/2007 1. The current rules pertaining to the administration and enforcement of the Colorado Noxious Weed Act state that the Commissioner will develop and implement state noxious weed management plans for selected List B species Eff 07/01/2007 33 2 State noxious weed management plans are necessary in order to coordinate appropriate actions at the private, local, state, and federal levels that will halt the continued spread of these List B species.

The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly affected by activities in the project area. However, determining the likelihood and extent of effects a project may have on trust resources typically requires gathering additional site -specific (e.g., vegetation/species surveys) and project -specific (e.g., magnitude and timing of proposed activities) information. Below is a summary of the project information you provided and contact information for the USFWS office(s) with jurisdiction in the defined project area.

The primary information used to generate this list is the known or expected range of each species. Additional areas of influence (AOl) for species are also considered. An AOl includes areas outside of the species range if the species could be indirectly affected by activities in that area (e.g., placing a dam upstream of a fish population, even if that fish does not occur at the dam site, may indirectly impact the species by reducing or eliminating water flow downstream). Because species can move, and site conditions can change, the species on this list are not guaranteed to be found on or near the project area. To fully determine any potential effects to species, additional site -specific and project -specific information is often required. Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary information whether any species which is listed or proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal agency. A letter from the local office and a species list which fulfills this requirement can only be obtained by requesting an official species list from either the Regulatory Review section in IPaC (see directions below) or from the local field office directly.

Landbirds: Migratory birds that are displayed on the IPaC species list are based on ranges in the latest edition of the National Geographic Guide, Birds of North America (6th Edition, 2011 by Jon L. Dunn, and _Jonathan Alderfer). Although these ranges are coarse in nature, a number of U.S. Fish and Wildlife Service migratory bird biologists agree that these maps are some of the best range maps to date. These ranges were clipped to a specific Bird Conservation Region (BCR) or USFWS Region/Regions, if it was indicated in the 2008 list of Birds of Conservation Concern (BCC) that a species was a BCC species only in a particular Region/Regions. Additional modifications have been made to some true: rtxpiore LucaLIUri rage ' ui i2, ranges based on more local or refined range information and/or information provided by U.S. Fish and Wildlife Service biologists with species expertise. All migratory birds that show in areas on land in IPaC are those that appear in the 2008 Birds of Conservation Concern report. Atlantic Seabirds: Ranges in IPaC for birds off the Atlantic coast are derived from species aistribution models developed by the National Oceanic and Atmospheric Association (NOAA) National Centers for Coastal Ocean Science (NCCOS) using the best available seabird survey data for the offshore Atlantic Coastal region to date. NOAANCCOS assisted USFWS in developing seasonal species ranges from their models for specific use in IPaC. Some of these birds are not BCC species but were of interest for inclusion because they may occur in high abundance off the coast at different times throughout the year, which potentially makes them more susceptible to certain types of development and activities taking place in that area. For more refined details about the abundance and richness of bird species within your project area off the Atlantic Coast, see the vortheasE Ocean Data Portal. The Portal also offers data and information about other types of taxa that may be helpful in your project review. About the NOAANCCOS models: the models were developed as part of the NOAANCCOS project: Integrative SJatistica Neiode;ing and Predictive N./lapping of Marine Bird Distributions and Abundance on -!e Atlantic lc:tei- Condrne: ,a! Shelf. The models resulting from this project are being used in a number of decision-support/mapping products in order to help guide decision - making on activities off the Atlantic Coast with the goal of reducing impacts to migratory birds. One such product is the :'lortneast_ OcEsn Data Portal, which can be used to explore details about the relative occurrence and abundance of bird species in a particular area off the Atlantic Coast. All migratory bird range maps within IPaC are continuously being updated as new and better information becomes available. Can I get additional information about the levels of occurrence in my project area of specific birds or groups of birds listed in iPaC? Landbirds: The Avian Knowledge Network (AKN) provides a tool currently called the "Histogram Tool", which draws from the data within the AKN (latest,survey, point count, citizen science datasets) to create a view of relative abundance of species within a particular location over the course of the year. The results of the tool depict the frequency of detection of a species in survey events, averaged between multiple clatasets within AKN in a particular week of the year. You may access the histogram tools through the _Migratory Bird Programs AKN Histogram Tools webpage. The tool is currently available for 4 regions (California, Northeast U.S., Southeast U.S. and Midwest), which encompasses the following 32 states: Alabama, Arkansas, California, Connecticut, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, New Hampshire, New jersey, New York, North, Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee, Vermont, Virginia, West Virginia, and Wisconsin. true: r xpiore Locauo I rage to ut 1 In the near future, there are plans to expand this tool nationwide within the AKN, and allow the graphs produced to appear with the list of trust resources generated by IPaC, providing you with an additional level of detail about the level of occurrence of the species of particular concern potentially occurring in your project area throughout the course of the year.

The primary information used to generate this list is the known or expected range of each species. Additional areas of influence (AOl) for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly affected by activities in that area (e.g., placing a dam upstream of a fish population, even if that fish does not occur at the dam site, may indirectly impact the species by reducing or eliminating water flow downstream). Because species can move, and site conditions can change, the species on this list are not guaranteed to be found on or near the project area. To fully determine any potential effects to species, additional site -specific and project -specific information is often required. Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary information whether any species which is listed or proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, or licensed by any Federal agency.

Situated west of Brighton, Colorado and adjacent/west of the South Platte River, the two proposed mine sites (east and west cells) are bisected by Tucson Street between 160th and 168th Avenue (see Attachment A - Figure 1). The proposed Project area is located in Township (1) 1 South, Range (R) 67 West, Section (S) 1 and T1 North, R67 West, S36. The proposed conveyor system would eliminate traffic concerns associated with the roads intersected by the Project. The Project would feature perimeter seeded berms during mining and buffer areas on 160th Avenue and along the South Platte River. Upon completion of mining, the two Project cells would be used for a water storage facility and Aggregate Industries would donate a parcel of land south of 160th Avenue as a conservation easement or open space to the local community. Mining operations are scheduled to start in the summer of 2021 and continue for an eight year period. Purpose and Need Migratory birds are protected by the 1918 Migratory Bird Treaty Act (MBTA) 16 United States Code 703-712. The MBTA affords protection to native migratory birds of North America, along with their nests and eggs. In an effort to comply with federal law, surveys were conducted for nesting raptors within the Project area. The purpose of the surveys was to identify the location and phenology of nesting raptor species in an effort to avoid effects on nesting birds that could lead to direct or indirect injury, loss of productivity, or nest abandonment. These effects to migratory birds include adults and their young or eggs. In addition to the federal protection awarded to migratory birds underthe MBTA, the western burrowing owl (Athene cunicularia) is listed as a state of Colorado threatened species and protected under Colorado Revised Statutes (CRS) Title 33, Parks and Wildlife 33-2-105. Occupied and remnant black - tailed prairie dog colonies occurthroughout the Project area, offering suitable habitat forthe burrowing owl. Because construction is scheduled to begin during the burrowing owl breeding season (March 15 to October 31), surveys for nesting burrowing owls were conducted according to Colorado Parks and Wildlife (CPW) recommended survey protocol. Methods Prior to the nesting surveys, a desktop review was conducted of the Project area for avian species diversity and previously recorded raptor nests. The desktop analysis involved the review of publicly available data including aerial imagery, U.S. Geological Survey topographic and vegetation data, and proprietary CPW spatial data of known raptor nest locations (CPW 2020a). Tucson South Sand and Gravel Mine Project I Adams County, Colorado Raptor and Burrowing Owl Nest Survey Based upon the desktop review, a survey area was identified which encompassed the proposed mine sites and conveyor system. The survey area for the general raptor survey extended up to 400 meters beyond the Project area boundaries. However, surveys were not performed in residential neighborhoods or other developed areas that lacked suitable nesting habitat for raptors. The surveys were conducted on April 27, May 6, and May 13. Surveys for burrowing owls were conducted following the CPW recommended survey protocol. The burrowing owl surveys were conducted in the early morning hours within about 2 hours of sunrise. The survey approach for burrowing owls included a passive survey in combination with call -broadcast surveys using the burrowing owl's primary male (coo -coo) and alarm (quick -quick -quick) calls. The surveys were conducted within the proposed site cell boundary where prairie dog colonies occur. More survey points were designated in areas with a greater density of prairie dog activity and therefore with a higher probability of occupancy by burrowing owls. The limited topography of the Project site allowed for an unobstructed view up to about 300 meters surrounding each point. Passive surveys were also conducted along the proposed alignment of the conveyor system. Surveys for other raptors were conducted in the late morning on the same survey day(s). A passive pedestrian/walking survey of the Project area was conducted in search of visual, auditory, or behavioral signs indicative of nesting raptors. Results and Analysis The burrowing owl survey did not result in the detection or incidental sign of nesting burrowing owls in the Project area. However, the survey did result in the incidental detection of 46 total avian species, four inactive nests, and one occupied raptor nest (see Attachment A — Figure 2 and Table 1).

As determined during the survey, Nest 1 was occupied but was not currently active. The definition of an active nest is one which contains viable eggs and/or chicks. A nest becomes active when the first egg is laid and remains active until fledged young are no longer dependent on the nest for survival. An occupied nest is defined as a nesting location that is occupied and defended by a mated pair but for which an active nest has not been established. Based upon these definitions, the red-tailed hawk pair at Nest 1 were witnessed actively building a stick nest and copulating near the nest location on May 6th. On May 13th, the nesting pair were present at Nest 1 and one adult was observed standing in the nest. Therefore, the nest was confirmed to be occupied and was likely or soon to be active. The average initiation of egg incubation for red-tailed hawks in Colorado is around April 1 (Preston and Beane 2020). So, the pair of red-tailed hawks at Nest 1 are either late nesters orexperienced a nest failure and are initiating a second nesting attempt. FOR 12 Tucson South Sand and Gravel Mine Project I Adams County, Colorado Raptor and Burrowing Owl Nest Survey Nest 1 is located adjacent to County Road 23% and 200 meters north of 168th Avenue. Due to the proximity of the nest to 168th Avenue and adjacent mining activities, the nesting red-tailed hawk pair are believed to be moderately tolerant of human encroachment. A higher tolerance of human presence was verified during the survey when the nesting red-tailed hawks continued to build their nest and mate while the surveyor was within less than 100 meters of the nest location. If Nest 1 becomes active, the nest would remain sensitive to Project disturbance through August 15, 2021. The vegetation in the Project area is dominated by four vegetation communities, consisting of invasive annual grasslands, invasive annual / biannual forbland, forested riparian floodplain, and fallow agricultural land. Nesting activity for songbirds and other passerine species, particularly black -billed magpies (Pica hudsonia), was recorded within the Project area. During the survey, most avian diversity was recorded within the forested riparian floodplain and riparian/herbaceous wetland within the proposed east cell mine site. This area is dominated by plains cottonwood (Populus deltoides), peach - leaf willow (Salix amygdaloides), coyote willow (Salix exigua), and cattail species (Typha sp.). Wild turkeys (Meleagris gallopavo) were flushed while surveying this area. Although no active turkey nests were recorded, the species is likely to nest within the forest riparian flood plain or elsewhere with higher vegetation density and shrub cover. A comprehensive pre -construction survey for all migratory nesting birds would be conducted within one week of the start of mining activities. Avian species incidentally detected during the Project survey are listed in Table 2.

incidentally detected dunng the survey as well as four inactive nest sites and one occupied red-tailed hawk nest Seasonal restnctions on human encroachment of red- tailed hawks is typically I/3 mile radius of active nests for rural sites from February 15 through July 15 (CPW 2020b) While encroachment on rural nest sites is likely to cause nest abandonment, red-tailed hawks often become habituated to human environments in urban and suburban settings and will tolerate human encroachment to within as close as 100 meters of their nest (CPW 2020b) The nesting pair of red-tailed hawks in the Project area at Nest 1 are believed to be moderately habituated to human activities due to the regular vehicle traffic along 168th Avenue, agricultural and mining activities, and general human presence around the nest site Dunng the survey, the nesting pair at Nest 1 was tolerant of vehicle and foot -traffic of the surveyor to about 100 meters Due to the late season establishment of Nest 1, it is recommended that mining activities remain south of 168th Avenue or otherwise outside of the mapped 200 -meter buffer of the nest location until after August 15 The two proposed mine sites are located over 0 5 mile from Nest 1 Therefore, mining work within the boundaries of the proposed mine sites would not disturb Nest 1 regardless of the seasonal timing and extent of mining activities Raptors display a high degree of fidelity to nesting sites and will routinely rehabilitate and reuse existing nests Therefore, inactive nests identified in this report could become active in future nesting seasons Removing inactive nests would minimize the potential for nesting activity adjacent to the mine site throughout the life of the mining activities With the exception of eagle nests, a permit is not required to remove and destroy an inactive migratory bird nest, provided -that no possession of the nest occurs after its removal (USFWS 2018) However, it is recommended that only inactive nests identified in this report be removed prior to September 1 The removal of nests not specifically identified in this report is not recommended without technical guidance from the U S Fish and Wildlife Service (USFWS) or other technical expert Most bird species would nest in the Project area between April 1 and September 1 Raptors (including burrowing owls) could nest in the Project area between February 1 and October 31 If nesting activity not discussed within this report is detected dunng construction, the USFWS and/or other technical experts should be consulted to identify the ap p ro p nate impact minimization measure(s) to avoid effects on the nesting species Furthermore, an additional clearance survey for all nesting bird species would be performed no more than one week pnorto the start of mining work During this survey, the nesting status of Nest 1 would be venfied, and the construction approach would be modified as needed to avoid impacting the nesting raptor pair and/or other nesting birds The results of this nesting survey for the western burrowing owl and other nesting raptors species are valid and applicable for the 2021 nesting season Should mining activities and other Project -related work be delayed into 2022 or beyond, then an additional raptor nesting survey(s) would be required to identify and avoid impacting newly established nests Assuming that mining activities begin as scheduled in 2021, ongoing mining and habitat disturbances would discourage most nesting bud species (particularly raptors) from establishing nests within and near the Project area

Wildlife Assessment Site Description Savage and Savage biologists conducted an on -site wildlife 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 corridor 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 loarns and clays, generally underlain by aggregate with varying groundwater levels The significant 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 The area has been developed for aggregate resources, with little of the native vegetation communities remaining These areas have no tree overstory and no shrub understory Active and mactive agricultural areas dominate the remainder of the area adjacent to the proposed conveyor comdor 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 mammals, birds, reptiles, and amphibians A further review of wildlife species for which the Colorado Division of Parks and Wildlife has distribution maps on the Colorado Oil and Gas Conservation Commission web site (http //cogcc state co us/mfosys/Maps/wildlifemap cfm) did not reveal any sensitive wildlife habitat or surface restricted occupancy areas within or adjacent to the project site (see appended map) The closest wildlife feature of significance to the proposed conveyor corridor is a bald eagle nest and buffer zone located 4500 feet northeast During the on -site investigation several avian species and one mammal species were observed within and adjacent to the project site A northern hamer (Circus cyaneus), Exhibit H Page 1 red -winged blackbird (Agelams phoeniceus), and black -tailed prairie dogs (Cynomys ludovicianus) were all seen along the comdor No tracks, scat or nests were observed during our inspection Seasonal Use With the exception of bats, 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 the waterfowl, raptors, gallmaceous birds, pigeons, owls, and woodpeckers The majority of the shorebirds and passerines would use the site during the spring, summer, and fall for feedmg or resting durmg migration Amphibian and reptile species of the site are year- round residents Threatened and Endangered Species and Critical Habitat Potential habitat for the Preble's meadow jumping mouse (Zapus hudsonaus preblei) and Ute ladies' -tresses orchid (Spiranthes diluvialis) were evaluated based on results of a search of potentially occurring threatened or endangered species on the U S Fish and Wildlife Service web site for Weld and Adams Counties Additionally, bald eagle (Halaaeetus leucocephalus) nest locations and winter night roost locales were evaluated from the Colorado Oil and Gas Conservation Commission (COGCC) web site map of sensitive wildlife habitat and restricted surface occupancy areas for protected wildlife species Potential habitat exists for the Preble's meadow jumping mouse within the cottonwood nparian comdor immediately adjacent to the South Platte River As the proposed project location is not within or adjacent to the riparian corridor and does not include disturbance to potential Preble's meadow jumping mouse critical habitat, the potential for impacts to the mouse are negligible, and no further evaluation was undertaken If future project activities include disturbance to potential habitat, the permittee will obtain clearance and/or approval from the U S Fish and Wildlife Service No eagles or nests were observed during our investigation of the site The map of significant wildlife habitat from COGCC identified a bald eagle nest site, however, it is located over 4500 feet northeast of the closest proposed conveyor location No winter night roost areas were located within two miles of the project site Burrowing owls (Athene cunacularaa), a species of concern in Colorado, occupy abandoned prairie dog holes on the outskirts of prairie dog colonies No prairie dog Exhibit H Page 2 colonies were found within the project site, nor was evidence of burrowing owls observed Project Effects to Wildlife The Tucson Conveyor project site is proposed for transportation of aggregate materials to the Platte Processing Plant located east of Wattenberg, Colorado on U S Highway 85 Currently, over -the -road haul trucks are used to convey aggregate from the musing areas to the south to the processing plant Noise and air emissions from truck haulage are significantly greater than that from operation of the proposed conveyor system The operation of the conveyor may cause a temporary disturbance to wildlife Though elevated, the conveyor may interrupt direct movement of larger ungulates, and direct their travels to areas where the conveyor is more elevated Species such as raccoons, coyotes, beaver, deer, and raptors will continue to use the corndor during conveyor 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 conveyor project will remam active so long as aggregate resources can be economically transported to the processmg facility When mining operations move thither from the processing plant, the conveyor will be removed, and the corridor reclaimed At that point, any wildlife impacts from the conveyor operation will be elimmated Exhibit H Page 3 Literature Cited Colorado Division of Wildlife 1981 Ed Colorado Reptile and Amphibian Distribution Latilong Study , Colorado Division of Wildlife and The Denver Museum of

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nres142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses Soil scientists observed the steepness, length, and shape of the slopes, the general pattern of drainage, the kinds of crops and native plants, and the kinds of bedrock They observed and described many soil profiles A soil profile is the sequence of natural layers, or horizons, in a soil The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs) MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006) Soil survey areas typically consist of parts of one or more MLRA The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape Commonly, individual soils on the landscape merge into one another as their charactenstics gradually change To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils They can observe only a limited number of soil profiles Nevertheless, these observations, supplemented by an understanding of the soil -vegetation -landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries Soil scientists recorded the characteristics of the soil profiles that they studied They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units) Taxonomic classes are concepts Each taxonomic class has a set of soil characteristics with precisely defined limits The classes are used as a basis for comparison to classify soils systematically Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile After the soil 6 Custom Soil Resource Report scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research The objective of soil mapping is not to delineate pure map unit components, the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions Some components may be highly contrasting to the other components of the map unit The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas Soil scientists make many field observations in the process of producing a soil map The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist Observations are made to test and refine the soil -landscape model and predictions and to verify the classification of the soils at specific locations Once the soil -landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components Properties of each soil typically vary from one point to another across the landscape Observations for map unit components are aggregated to develop ranges of characteristics for the components The aggregated values are presented Direct measurements do not exist for every property presented for every map unit component Values for some properties are estimated from combinations of other properties While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests Soil scientists interpret the data from these analyses and tests as well as the field -observed characteristics and the soil properties to determine the expected behavior of the soils under different uses Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs Data are assembled from other sources, such as research information, production records, and field experience of specialists For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity Soil conditions are predictable over long periods of time, but they are not predictable from year to year For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and 7 Custom Soil Resource Report identified each as a specific map unit Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately 8 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols

on the detailed soil maps in a soil survey represent the soils or miscellaneous areas in the survey area The map unit descriptions, 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 14 Custom Soil Resource Report 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 Soils that have profiles that are almost alike make up a soil series Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement Soils of one 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 15 Custom Soil Resource Report 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 16 Custom Soil Resource Report Adams County Area, Parts of Adams
