The proposed mining operation will last approximately 2.5 years(including development, production, and site reclamation)of sand mining and processing. As seen in Exhibit C,there is a 100-foot-wide"excavation restricted area"that is oriented diagonally from the southwest to the northeast across the site boundary. This area includes an easement for the existing Kerr-McGee natural gas pipeline as well as a landowner well water pipeline. No excavation is to occur within this area in order to protect the pipeline. Project Phasing The lifespan of the project will be divided into four(4)phases, as described below and summarized in the attached drawing"Mine Plan, Sheet 3a": • Phase 1 will be developing the area,preparing it for mining. • Phase 2 will be mining the fines recovery Pit 2. • Phase 3 will be mining the Main Mine Pit. • Phase 4 will be reclaiming the site. Additional detail is provided below regarding the four project phases. Phase 1: Existing infrastructure (e.g., utilities, existing pipelines) and other easements will be surveyed, marked, and safeguarded. Runoff water retainment berms will be created around the site perimeter. Following the construction of these berms, organics will be cleared from the site and placed into a growth medium stockpile on the northeast corner of the site. Additional clay subbase and road base material will be brought in as needed to create internal mine haul roads. Organics removal will encompass the removal of the top 12 inches of organics for salvage and storage for re-use during reclamation.Phase 1 is anticipated to last one month. Phase 2: Following the excavation of the original Main Mine Pit from the 110 permit, this pit will be identified as Fines Recovery Pit#1. This pit will be utilized for fines recovery until Fines Recovery Pit#2 is fully excavated. During this time, Fines Recovery Pit#2 will be excavated and stockpiled on top of the Main Mine Pit area. This material will be the initial source for the run-of-mine (ROM) stockpile. This stockpile of material will be depleted before the Main Mine Pit excavation begins. This material will be processed through the plant until this stockpile is depleted. It is anticipated that development of the Fines Recovery Pit#2 will commence at the south end of the pit with a nominal 10%decline ramp. SaturnX Mine Colorado Sand Company LLC DRMS 112 Permit Application Page D-1 Fines Recovery Pit#1 will be roughly rectangular in shape,with dimensions of 575 feet by 240 feet. At a depth of 15 feet,the volume of excavated material will be roughly 46,000 cubic yards. Fines Recovery Pit #2 will be triangular in shape and will produce about one million cubic yards at a 15-foot depth. If deemed beneficial,these pits will be excavated to a depth of 40 feet,increasing overall volume of material mined. Excavated material from the fines recovery pit excavation will be considered ROM feedstock for the processing plant. Approximately 20% of the volume will be stockpiled in the wet plant feed hopper such that it is proximal to the wet plant processing area(ROM-1); and the remaining approximately 80%of that volume will be stockpiled atop the Main Mine Pit footprint area(ROM-2). With the Fines Recovery Pit#1 fully excavated from the previous 110 permit operations, processing will commence and wet plant reject(fines)will be slurried to the Fines Recovery Pit#1 via pipeline.The ROM stockpiled material will provide the initial feedstock material to the wet plant. Once the ROM-1 volume/tonnage is fully depleted, the ROM-2 stockpile will become the plant feedstock source. ROM-2 stockpile recovery will entail re-mining of the material. During this time, the Fines Recovery Pit #1 capacity will be exhausted and the wet plant reject (fines) will then be pumped via pipeline to Fines Recovery Pit#2. Phase 3:Once the Fines Recovery Pit#2 material stockpile is depleted,the Main Mine Pit will be excavated. This material will be transferred into the ROM stockpile and processed through the plant until the Main Mine Pit is depleted. Phases 2 and 3 are anticipated to last a combined 24 months. The Main Mine Pit will be approximately 2,373 feet by 2,424 feet at its largest dimensions.At 15 feet deep, the volume of excavated material will be roughly 2.5 million cubic yards. This pit will also be excavated to a maximum of 40 feet if deemed beneficial. Initial pit development will encompass the establishment of a pit perimeter berm that will serve both as a safety feature to delineate the full extent of excavation. Poly pipe will be installed in key, low lying areas around the pit, under the berms to allow surface water to flow into the pits for water retention. It is anticipated that development of the Main Mine Pit will commence at the west end of the pit with a nominal 10%decline ramp. The sand resource is an unconsolidated,eolian sand deposit that is anticipated to be relatively consistent in terms of size distribution and quality characteristics across the planned pit area.Due to the unconsolidated and free-flowing nature of the material, blasting is neither required, nor proposed. All material extraction will be accomplished via direct excavation, utilizing either a hydraulic excavator, scrapers, and/or front- end loader(s). Phase 4:Once the Main Mine Pit is depleted, site reclamation will begin.Equipment will be removed from the site.Constructed haul roads will remain in place as assets to the landowner.Reclamation will consist of spreading the stored growth medium material over the site and other tasks per the reclamation plan in Exhibit E. Phase 4 is anticipated to last approximately 2 months. Throughout all phases,dust control will be performed on site using water sprayer trucks.All pits are planned to be excavated to 15 feet below grade. However, pits may be up to 40 feet deep if reserves base is found deeper than anticipated. The slope of the pit edges will be limited to the natural angle of repose of the ground at a 1.5H:1 V slope.This slope has been tested on site and has been verified to be stable.Stormwater landing within the site area will be temporarily retained on site within the existing pits. SaturnX Mine Colorado Sand Company LLC DRMS 112 Permit Application Page D-2 Mining Operations Sand will be mined from an open-cut pit by hydraulic excavator, scraper, and/or front-end loader, loading to articulated haul trucks (or being hauled by scrapers), for subsequent transport to a ROM stockpile (see attached drawing"General Site Layout, Sheet 1"). ROM stockpile material will then be introduced to the "wet plant" (see attached drawing"Wet Plant Equipment, Sheet 4"). The wet plan will utilize mechanical separation processes(freshwater wash)to produce a#20/#140(i.e.,greater than 20 mesh but less than 140 mesh) interim product. Oversize material (i.e., that greater than 20 mesh) will be scalped off prior to the wash process and routed to an oversize reject stockpile. Undersize material (less than 140 mesh) will be generated during the wash process(which will employ cyclones and attrition cells). The fines reject will be slurried to a dedicated fines recovery pit. The resultant #20/#140 size fraction interim product will be temporarily stockpiled to allow for drain down and will be stored in a decant stockpile (WP023 on"Wet Plant Equipment, Sheet 4"). Wet plant process and stockpile decant waters will be recovered to the extent practicable and routed through a clarifier unit in order to maximize process water recycle. Material from the decant stockpile will be loaded via front-end loader to a feed hopper and a gas-fired rotary kiln dryer unit for drying. The dried material will then be introduced to a dry screening plant(see attached "Dry Plant Equipment, Sheet 5" for details). There, the dried material will be further separated by size fraction(screening),with the oversize(i.e.,that greater than 40 mesh) reporting to the non-spec stockpile, and any trace material smaller than 140 mesh will report to the non-spec stockpile thereby facilitating the production of a singular#40/#140 end-product. The #40/#140 end-product will be delivered via telescoping conveyor to a set of twin storage buildings, from which the material will be drawn by front end loader to a feed hopper for belt conveyor loading of over-the-road (OTR) tractor trailer units. Tractor trailer units will enter the Permit Area via the existing ranch service road and exit that road onto the Permit Area's north-side loadout loop road. The OTR trucks will traverse the loop road in clockwise fashion,continuing to the loadout/scaling area(see attached drawing "Loadout Layout, Sheet 7"for truck loading layout). Once loading is completed,the trucks will continue west on the short remainder of the loop road along the perimeter of the Permit Area,in order to re-access the existing ranch service road for return to Weld County Road 59. Water Treatment Chemicals During the water clarification process, polyacrylamide anionic flocculants and polyDADMAC cationic coagulants will be used. Both chemicals are readily soluble in water and have poor adsorption to minerals and organic matter. The acrylamide monomer will be recycled in the clarifier with minimal loss. Any chemical that does escape the system will biodegrade and not impact the environment. The DADMAC monomer also readily biodegrades in water and soil and as such,it is expected that a significant amount of biodegradation will occur in the soil and water beneath the wet sand piles. See Appendix A for the MSDS for these chemicals. SaturnX Mine Colorado Sand Company LLC DRMS 112 Permit Application Page D-3 Equipment The mining equipment roster to be employed at the SaturnX Project is anticipated to include,but not limited to,the following representative units: • John Deere 350 Hydraulic Excavator • Water Truck • John Deere 644 Front-End Loader • Wheeled Scraper • John Deere 850 Dozer • Roller Compactor • John Deere 410 Articulated Dump Truck • Ford F250 Pickups Roads There is a singular point of entry to the Permit Area, via the existing ranch service road that enters the property at a location generally 3 miles north of Keenesburg along Weld County Road 59(extending south to north),specifically at the pre-established address 10004 County Road 59 Keenesburg, CO 80643 which was previously obtained for the 110 Limited Disturbance Permit.This service road is a 15-foot wide gravel- surfaced roadway that has historically been and is currently utilized for access to the ranch by ranch equipment and oilfield service truck traffic servicing the various oil and gas installations that are present throughout the property. It is planned to expand the road and access gate to be 30 feet wide to help traffic move smoother and safer. While approximately 500 feet of the existing service road will be utilized for Project Site ingress/egress, Routine maintenance, however, will be carried out, to include grading (as warranted) and dust control activities. The existing loadout loop road will be expanded to support two lanes of traffic from the existing one lane. It will commence at a turnout point approximately 500 feet northeast of the existing gated entry and loop around the Permit Area in a clockwise direction.The loadout loop road will accommodate one-way traffic, circulating in a clockwise manner.Empty trucks will enter the loop via the turnout and continue to the truck scale and product loadout facilities, at which point they will be loaded with saleable product. The trucks will then proceed along the remainder of the loop, returning to the main ranch service road, after which they will proceed southwesterly through the gated entry and thence to Weld County Road 59, and ultimately,onward to Interstate 76. Water The site has been designed to take advantage of site-specific drainage characteristics such as high infiltration and natural drainage towards the northeast. Due to the limited area of influence associated with the Permit Area location,no specific run-on or run-off potential is anticipated. The site is situated where it has higher localized elevation compared to the surrounding area. Impervious area will not be increased as a result of the project. WCR 59 to the west and Ennis Draw to the south and east will minimize run-on to the site. The planned perimeter loadout loop road and associated berming will serve to eliminate run-off potential from the active mining and processing areas. Silt fencing will be installed around the site perimeter prior to the initiation of site construction activities and will remain in place following the installation of the water retainment berms as berm support devices. The silt fences will be left in place within the proposed retainment berms, but not be considered erosion and sediment control devices once the water retainment SaturnX Mine Colorado Sand Company LLC DRMS 112 Permit Application Page D-4 berms are constructed. The berms will serve the long-term function of controlling sediment runoff. The water retainment berms will be maintained for the full duration of active mining and reclamation operations. All onsite precipitation accumulation will be retained within the confines of the permit area and stored within the fines recovery pits and main mine pit. Sufficient freeboard operating capacity has been provided within the fines recovery pit design. The pits will act as infiltration ponds, returning water to Ennis Draw via subsurface flow.Stormwater collected in the open mine will be managed in accordance with a Colorado Discharge Permit System (CDPS) permit for this operation. If the stormwater fails to infiltrate, it will be pumped out of the pit and returned to the natural drainage within 72-hours in accordance with Colorado water law. Sediment generated from localized stormwater runoff and surface drainage will be managed according to the Stormwater Management Plan (SWMP) that will be developed in conjunction with the CDPS permit. The SWMP will be designed to prevent the contact and transport of potential contaminants by stormwater flows by using the pits as settling ponds.The water quality at the discharge will be monitored and additional settling ponds will be constructed, and filter bags will be installed on the pumps if there's high turbidity at the outlet to Ennis Draw. • SaturnX Mine Colorado Sand Company LLC DRMS 112 Permit Application Page D-5 t I N 1 LGeneral Notes 1 Various equipment and finished product storage areas will utilize temporary composite or timber matting to reduce the need foundations r and reduce ground Growth disturbance in those areas medium stockpile 2 Operating hours for the plant are anticipated to be 24 days/wk, 7 dayss/wkk,,although shorter hours of operation Fines Recovery Pit#2 may be established 3 Maximum anticipated workers per shift is • 15 Shifts are planned to be 12—hour shifts 2 of these shift personnel are managers and up to 13 of he Pipeline easement area Existing ranch road personnel el will be general labor Run of Mine(ROM)stockpile Main Mine Pit .r O No Revision/Issue Dote Covered sand storage area Colorado Sand Company LLC POC Seth Sanders Jt' 842 W Sam Houston Parkway N Suite 110 Previously permitted 110 site(9 9 acres) Houston TX 77024 Fines Recovery Pit#1 FnoJ't No,,end Wm.

The proposed Permit Area is located upon privately-owned lands that are wholly controlled by Guttersen Ranches LLC,an entity principally engaged in the cattle industry. The Reclamation Plan has been developed in direct consultation with Guttersen Ranches. As discussed in Exhibit D, the main mine pit, fines recovery pits, and perimeter loop roadways will be stripped of the top 12 inches of growth medium prior to mining. This growth medium will be used during the reclamation process after mining, with the objective of establishing a minimum 6-inch thick layer of growth medium prior to reseeding. Growth medium will not be replaced in areas that were not stripped of growth medium but are disturbed during mining(e.g.,material stockpile areas,unimproved roads,and those areas underlying temporary modular structures). These areas will be graded and smoothed in advance of revegetation. Improved roads will remain in place for future use by the landowner. Reclamation will begin following the conclusion of mining. The first step of reclamation is to remove all temporary structures from the site. Grading of the pits will then be done to achieve 3H:1 V slopes or flatter. Following slope grading,revegetation will begin in a two-step process: 1. Moving a minimum of 6 to 12 inches of the previously stripped growth medium back to roads and pits. If more topsoil is needed, additional material will be imported to achieve the 6 to 12 inch minimum for growth medium. 2. Re-seeding the site to return the site back to its pre-mining conditions. Reclaimed Slopes The fines recovery pit will be filled by the fines slurry during the mining process. It is anticipated that the fines recovery pits will be filled to near or at full capacity by the end of the mining process, resulting in little to no excavated slope exposure and only minor depressions may remain. In the event that more than a minor depression remains,the slopes will be maintained to a maximum slope of 3H:1 V.After the slopes are graded,if needed,a minimum of 6 to 12 inches of growth medium will be placed atop the fines material. The addition of the growth medium will reduce remaining depression and provide soil for the growth of new plants. Revegetation Revegetation is largely focused on reestablishment of the rangeland plant species. No trees or shrubs are planned as a component of the revegetation process. Such rangeland revegetation activities will be carried out in a manner consistent with that recommended by Weld County's reseeding guidelines (https://www.weldgov.com/departments/public works/weed management/controlling weeds/reseeding), with the seed mix and application rate developed per the "sandy site" mix specification shown below in Table E-l. Drill seeding and straw crimping mulching(two(2)tons per acre of certified weed free straw) will be employed across the whole site,unless a more appropriate seeding method is determined. SatumX Mine Colorado Sand Company LLC DRMS 112 Permit Application Page E-1 All revegetation activities will be focused on reestablishment of the rangeland grass species. The subject site, in its pre-mining condition,has no established trees of any species at any location within or proximal to the Permit Area. Sagebrush is scattered throughout the immediate area in a relatively low density. However,this is considered an invasive species and no attempt will be made to re-establish the community.

PLS/Acre= Pounds of Pure Live Seed per Acre; assumes drilled seed, and would require twice the amount for broadcasted seed method Structures and Other Features All structures associated with the SaturnX Project are anticipated to be of a temporary(modular or portable) type of construction and are to be removed from the site upon site closure and the start of reclamation. Similarly, any and all appurtenant or ancillary infrastructure/facilities (e.g., fuels storage tanks, etc.) will also be removed from the site. No ponds or impounding features are anticipated to remain post-closure. The remnant main mine pit depression will serve as a natural infiltration feature. Side-slopes will be established at a minimum 3H:1V to ensure ease of accessibility to the area by livestock, consistent with the prescribed post-mining land use designation of rangeland. To the extent minor run-on and/or run-off diversion features are present, such features will be removed during the site regrading effort. The overarching objective will be to reestablish natural drainage patterns (e.g., toward the Ennis Draw to the northeast) through the affected area (with the exception of the main mine pit depression)to mimic pre-mining conditions to the maximum extent practicable. Sediment fencing will have been initially deployed around the full perimeter of the Permit Area. This sediment fencing will be retained (and maintained, as necessary) until the water retention berms are constructed, after which time the silt fences will serve to provide supplementary strength to the water retention berms but will not be maintained as independent sediment control structures. The water retention SatumX Mine Colorado Sand Company LLC DRMS 112 Permit Application Page E-2 berms will be maintained throughout the duration of all mining and processing operations, and will be reestablished and/or remain in-place until vegetation is re-established. In addition,ground-staked sediment log barriers will be installed approximately 25 to 50 feet in length at approximately 150-foot intervals within the (pre-existing and retained) natural drainage swale extending from the southwest comer of the Permit area and exiting the north edge of the Permit Area at its approximate mid-point and along the approximate mid-slope elevation within the reclaimed main mine pit. A five (5) year post-closure maintenance and monitoring program is being incorporated into the reclamation cost estimate for this site. Wildlife All reclamation aspects will take into account the safety and protection of wildlife on the site. The area to be mined consists of rangeland that does not serve as wildlife habitat to any protected or endangered species (see Exhibit H). According to the National Wetlands Inventory(https://www.fws.gov/wetlands/)there is a strip of riverine habitat to the east of the site as part of the Ennis Draw that may be considered jurisdictional wetlands which could house wildlife. Mining operations will maintain appropriate setbacks from this area and therefore will not impact this strip of riverine habitat. Mining pits will be reclaimed such that slopes are less than a 3H:1V slope,allowing access for cattle and other wildlife present in the area.

An ephemeral drainage feature named Ennis Draw (which is depicted on the USGS "Klug Ranch, Colorado" and "Tampa, Colorado" 7.5° topographic quadrangles, respectively), is located approximately one third mile to the east of the permit area. Due to both the nature of the project and readily observable site characteristics,documentation of regional and localized water resources has been completed through a review of reasonably available information,to include topographic mapping, well logs, geologic interpretation and literature review, in conjunction with limited scope,but media-specific,field investigations. Surface Water Resources The immediate area surrounding the SaturnX Project generally consists of arid upland habitat devoid of any surface water with the exception of one shallow drainage feature that extends through the east portion of Section 12.This named drainage feature(Ennis Draw)is depicted on USGS topographic mapping(Tampa, Colorado 7.5° Quadrangle),and is located approximately '/4 mile to the east of the easternmost permit area boundary line. Ennis Draw sources from an area approximately 1 V2 miles to the south of the permit area. It then courses directly south to north along the easternmost portion of the southerly abutting Section 13, entering the subject Section 12 at or near the Section's extreme southeast corner. It then continues directly north immediately interior and parallel to the Section 12 east line and appears to effectively terminate(possibly due to infiltration)within the SE '/4 of the northerly abutting Section 1. Proximal to the Section 12 southeast corner, the nominal bottom elevation of Ennis Draw is at or about 4,830 ft. amsl, with the feature exhibiting an approximate 1% stream gradient downward to the north. A small surface water feature is present approximately 400 feet to the west of the main course of Ennis Draw (in the NE 1/4 of the SE 1/4 of Section 12). This feature is utilized by Guttersen Ranches LLC for stock watering purposes. Situated up gradient of and between two localized higher elevation areas,the feature is within and/or establishes a separate small,but discrete drainage that is tributary to Ennis Draw at a location approximately '/4-mile further down gradient. The surface water feature itself is approximately '/4-mile distant(to the east-northeast)from the permit area. A larger surface water feature(estimated to be approximately 6 to 8 acres in surface area)is located exterior to Section 12, in the extreme southeast corner of the easterly abutting Section 7; T2N; R63 W. This feature is situated within the main stem of Ennis Draw and it is similarly owned and utilized by Guttersen Ranches LLC for stock watering purposes. This feature is approximately'/2-mile directly east of the permit area. Topographic mapping also depicts another surface water feature present at a location approximately''/2-mile east-southeast of the permit area.This feature is situated some 1,000 ft.(mil)up gradient,on the main stem SaturnX Mine Colorado Sand Company LLC DRMS 112 Permit Application Page G-1 of Ennis Draw.Property ownership of this feature is indicated to be Helena&Vince Gerkin;it is presumed that the feature is, or has been, similarly utilized for stock watering purposes. Field observations of the Ennis Draw feature carried out in December 2018 noted that the feature, while depicted as continuous on topographic mapping, did not exhibit evidence of a stream channel or a defined bed and bank. Within Section 12, much of the drainage bottom was observed to be vegetated and subject only to seasonal water presence (thus confirming the indicated ephemeral characteristics per USGS map depiction).No flowing water was observed during the field investigation. Several National Wetlands Inventory(NWI)mapped wetlands are located within and/or adjacent to Ennis Draw. Field crews investigated some of these mapped features to confirm the presence of wetlands, with presence/absence determinations based on those protocols described in the 2012 Regional Supplement to the Corps of Engineers Wetland Delineation Manual, Great Plains Region - Version 2.0. The approach recognizes the three parameters of hydrology,vegetation,and soils to identify wetlands.Hydric soils were observed in several soil test pits evaluated throughout the drainage. A Wetland Determination Data Form was completed to confirm the presence of wetlands and document conditions at Sample Point W-1 (with location coordinates of 40.15713 North Latitude; -104.49048 West Longitude,within the SE 'A of Section 12), which confirmed the presence of hydrophytic vegetation, hydric soil, and wetland hydrology at the location;however,no wetland delineations were carried out in conjunction with the field effort. Groundwater Resources The project area falls within the South Platte River Valley. Surficial aquifers therein generally contain the shallowest groundwater (where present), and consist of Quaternary deposits of alluvial gravel, sand, silt, and clay; or, eolian sand and silt. The surficial aquifer associated with the South Platte River is known to range in thickness from about 20 to 200 ft. and range in width from about 1 to as much as 15 miles. Inasmuch as the permit area is situated in excess of 15 miles to the south of the course of the South Platte River,the site does not readily exhibit the presence of alluvial gravels, instead exhibiting the presence of a thick (up to 30 ft. or greater) surficial zone comprised of eolian sand and silt, which, in many locations throughout the immediate area,exhibit characteristics of dune-type deposits. The permit area is situated near the extreme northern extent of the Denver Basin aquifer system, which underlies an area of about 7,000 square miles that extends roughly from Greeley south to near Colorado Springs. The Denver Basin aquifer system is not well connected to other major aquifers in the area,and the surficial aquifer along the South Platte River Valley is the only other major aquifer near the Denver Basin. Shallow,discontinuous surficial aquifers overlie parts of the Denver Basin aquifer system,primarily along small streams that are tributary(from the south)to the South Platte River.The Denver Basin aquifer system consists of four discrete aquifers that are present in five geologic formations. The permit area is located along the borders of the Arapahoe and Laramie Fox Hills aquifer units. SaturnX Mine Colorado Sand Company LLC DRMS 112 Permit Application Page G-2 Two registered groundwater wells have been identified that can be considered proximal to the Permit Area, as follows: Stock watering Well (Permit No. 159505) located in the SW '/4 of the SW '/4 of Section 12: This well is situated at a location approximately 100 ft. east of the Section 12 west line and 100 ft.north of the Section 12 south line; or, immediately proximal/adjacent to the permit area. The well was drilled in April 1991, and reportedly completed to a total depth of 600 ft., with the screened interval being between 540 ft. and 600 ft. bgs. Lithologic data indicates "sand" and "clay" materials to a depth of 15 ft.bgs,followed by alternating"shale"and"rock" strata to a depth of 397 ft.A"sand"zone was again recorded as being present from 397 ft.to 520 ft.,followed by a thin"rock" zone present between 520 and 524 ft.,and"sand" again present between 524 ft. and 600 ft.bgs. Stock watering Well(Permit No. 75234)located in the SW'A of the SW'/4 of Section 7;T2N;R63 W): This well is situated at a location 300 ft. north of the south line and 600 ft. east of the west line of Section 7, which would place it to the east of Ennis Draw,and proximal to one of the above-discussed impoundment features. This location is about Y2-mile due east of the permit area. A Statement of Beneficial Use was located;however,no Well Construction and Test Report is available on the Office of State Engineer website. Groundwater in the area is hydraulically connected to Ennis Draw, which is downgradient from the site. Depth to groundwater ranges from 22 feet below the surface at the west end of the site to 5 feet below the surface at the east end of the site,closer to Ennis Draw. Water Requirements The mining operation consists of sand production and will have the following water requirements: 1. Evaporation of water from washed sand 2. Evaporation of water from clarifier tailings 3. Dust control 4. Evaporation from open water surface if the groundwater table is reached The total quantity of water to be consumed during the mining operation is estimated to be 226,439 gallons per day,as shown in Table G-1. The estimated usage includes requirements for process water make-up that would be attributed to dust control applications and entrainment in fines disposed of within the fines recovery pit. The duration of mining will last approximately 24 months. Table G- 1 Daily Water Requirements at Keenesburg(gallons/day) Water on washed sand 33,217 Water in clarifier tailings 174,322 Dust control 18,900 Total 226,439 SaturnX Mine Colorado Sand Company LLC DRMS 112 Permit Application Page G-3 Consumptive Use Water used for washed sand,clarifier tailings,and dust control will be imported to the site from the well(s) that pump from the Laramie-Fox Hills aquifer and will not result in consumptive use depletions to an alluvial aquifer or hydraulically connected surface water system. As discussed in Exhibit D,excavation is not intended to expose groundwater.In the event that groundwater is exposed,area will be buried under two feet of dirt and mining will be moved to another location. Based on the above, there will be no consumptive use to any alluvial aquifer system or hydraulically connected surface water system as a result of the proposed project. Water Source The applicant is currently evaluating two(2)options for the required water supply, as follows: 1. Purchase of water from an industrial supply well currently under development. The well is being completed within the Laramie-Fox Hills aquifer and is owned and operated by Guttersen Ranches LLC. The well is located proximal to the Permit Area within Section 12. Water would be delivered to site via a temporary, buried, water pipe system extending from the well-head location to the Keenesburg Project Permit Area. This well was permitted under Permit # 83340-F and has a maximum permitted annual withdrawal of 160 acre-feet and maximum flow rate of 100 GPM. 2. Purchase of water and trucked delivery of the water to the Keenesburg Project facilities from an existing industrial supply well located on land owned by Guttersen Ranches LLC, and which is completed within the Laramie-Fox Hills aquifer system at a depth in excess of 500 feet below ground surface. This well was permitted under Permit# 79782-F and has a maximum permitted annual withdrawal of 160 acre-feet and maximum flow rate of 100 GPM. The daily use will be 0.69 acre-feet per day(253 acre-feet per year)and require a rate of 157.25 GPM. See Table G-2 for a water balance summary detailing what water is available for use and what the demand is. Between the two sources,there will be adequate water supply to meet the anticipated demand. The mining period is anticipated to last 24 months.

Onsite water storage will consist of a bulk water storage tank(21,000-gallon capacity)located proximal to the wet plant facilities. In addition,in-process vessels,to include the clarifier unit(45,000-gallon capacity) and the "clear well" (13,000-gallon capacity)will augment the water supply circuit. No provision is made for personal hygiene uses (such as showers, etc.), as such activities will be done offsite. Onsite sanitation facilities will be provided by portable toilet units,to be serviced on a regular basis by a third-party contractor.Potable water will be delivered to the site and will be serviced on a regular basis by a third-party contractor. SatumX Mine Colorado Sand Company LLC DRMS 112 Permit Application Page G-5 EXHIBIT H WILDLIFE INFORMATION The project area was reviewed by RETTEW Associates, Inc. for the potential occurrence of sensitive wildlife species as listed by both the U.S. Fish and Wildlife Service (USFWS) and Colorado Parks and Wildlife (CPW). Data was evaluated from desktop and field observations made on December 19 and 20, 2018.Based on their range and habitat requirements,the following wildlife species have potential to occur in the area: • Burrowing owl • Mountain plover • Black-tailed prairie dog • Northern pocket gopher Field observations made in December 2018 identified a red-tailed hawk flying overhead,jackrabbits near the project area, and rodent burrows and tracks scattered throughout the area. There were no suitable trees for nesting raptors observed,no evidence of prairie dogs or burrows observed,and no migratory bird nests, dens, or other wildlife signs observed. The presence of the above species is possible, but none were identified during the field survey. In addition,the USFWS Information,Planning,and Conservation(IPaC)system identified 5 USFWS Platte River Species. These species should be considered if a water-related activity or use is proposed that may lead to downstream depletions of the river system in Nebraska. Additional species that are listed as potential, but not likely, to appear in the area are the Colorado butterfly plant, the Ute ladies'-tresses, the western prairie fringed orchid, and the Preble's meadow jumping mouse. See section 3.2 of Attachment B —"Environmental Resource Report"prepared by RETTEW Associates,Inc. Due to the lack of evidence of protected species encountered on the site visits,it is unlikely that the mining operation will adversely impact protected species. Most of the project area consist of arid upland habitat devoid of any surface water. However, there is a drainage and wetland area located just east of the site. The drainage is identified as Ennis Draw and the wetlands appear on the National Wetlands Inventory (NWI) maps. Field observations made in December 2018 confirmed the presence of these wetlands and identified dense vegetation and water that likely provided habitat for passing birds,wildlife,and cattle. Field observations suggest that portions of the draw are only seasonal and no flowing water was observed at the time of visit. Mining operations will maintain appropriate setbacks from this area and therefore is not expected to impact this strip of riverine habitat.

Examples are bedrock, cemented layers, dense layers, and frozen layers. This theme presents the depth to any type of restrictive layer that is described for each map unit. If more than one type of restrictive layer is described for an individual soil type, the depth to the shallowest one is presented. If no restrictive layer is described in a map unit, it is represented by the">200"depth class. This attribute is actually recorded as three separate values in the database.A low value and a high value indicate the range of this attribute for the soil component.A"representative"value indicates the expected value of this attribute for the component. For this soil property, only the representative value is used.

Vegetation around the wetlands was distinctly different than the vegetation around the majority of the site.Most of the project area consists of grazed grasslands containing patches of sagebrush and a significant amount of bare ground(30 to 70 percent). Shrub cover ranged from 0 to 30 percent cover. The Web Soil Survey conducted for the parcel area showed Loup-Boel loamy sands (35), Olney loamy sand(44,45),Osgood sand(49),and Valent sand(69,70),see Exhibit I.The attached table titled Rangeland and Forest Vegetation Classification,Productivity and Plant Composition was created using the same Web Soil Survey Area of Interest.This table points out understory vegetation in which each type of soil supports. These vegetation types include switchgrass, little bluestem, reedgrass,western wheatgrass, sand bluestem, slender whetgrass, yellow Indiangrass, sideoats grama, sand dropseed, thickspike wheatgrass, prairie sandreed,blue grama,needle and thread,prairie Junegrass, sand sagebrush,and sedge. No crops exist in the project area. SaturnX Mine Colorado Sand Company LLC DRMS 112 Permit Application Page J-1 Rangeland and Forest Vegetation Classification,Productivity,and Plant Composition--Weld PAS Permit Application County,Colorado,Southern Part Rangeland and Forest Vegetation Classification, Productivity, and Plant Composition In areas that have similar climate and topography, differences in the kind and amount of rangeland or forest understory vegetation are closely related to the kind of soil. Effective management is based on the relationship between the soils and vegetation and water. This table shows, for each soil that supports vegetation, the ecological site, plant association, or habitat type; the total annual production of vegetation in favorable, normal, and unfavorable years; the characteristic vegetation; and the average percentage of each species. An explanation of the column headings in the table follows. An ecological site, plant association, or habitat type is the product of all the environmental factors responsible for its development. It has characteristic soils that have developed over time throughout the soil development process; a characteristic hydrology, particularly infiltration and runoff that has developed . over time; and a characteristic plant community(kind and amount of vegetation). The hydrology of the site is influenced by development of the soil and plant community. The vegetation, soils, and hydrology are all interrelated. Each is influenced by the others and influences the development of the others. The plant community on an ecological site, plant association, or habitat type is typified by an association of species that differs from that of other ecological sites, plant associations, or habitat types in the kind and/or proportion of species or in total production. Descriptions of ecological sites are provided in the Field Office Technical Guide, which is available in local offices of the Natural Resources Conservation Service(NRCS). Descriptions of plant associations or habitat types are available from local U.S. Forest Service offices. Total dry-weight production is the amount of vegetation that can be expected to grow annually in a well managed area that is supporting the potential natural plant community. It includes all vegetation, whether or not it is palatable to grazing animals. It includes the current year's growth of leaves, twigs, and fruits of woody plants. It does not include the increase in stem diameter of trees and shrubs. It is expressed in pounds per acre of air-dry vegetation for favorable, normal, and unfavorable years. In a favorable year, the amount and distribution of precipitation and the temperatures make growing conditions substantially better than average. In a normal year, growing conditions are about average. In an unfavorable year, growing conditions are well below average, generally because of low available soil moisture.Yields are adjusted to a common percent of air-dry moisture content. Characteristic vegetation(the grasses,forbs, shrubs, and understory trees that make up most of the potential natural plant community on each soil) is listed by common name. Under rangeland composition and forest understory, the expected percentage of the total annual production is given for each species making up the characteristic vegetation. The percentages are by dry weight for rangeland. Percentages for forest understory are by either dry weight or canopy cover. The amount that can be used as forage depends on the kinds of grazing animals and on the grazing season. usDA Natural Resources Web Soil Survey 8/20/2019 Conservation Service National Cooperative Soil Survey Page 1 of 6 Rangeland and Forest Vegetation Classification,Productivity,and Plant Composition--Weld PAS Permit Application County,Colorado,Southern Part Range management requires knowledge of the kinds of soil and of the potential natural plant community. It also requires an evaluation of the present range similarity index and rangeland trend. Range similarity index is determined by comparing the present plant community with the potential natural plant community on a particular rangeland ecological site. The more closely the existing community resembles the potential community, the higher the range similarity index. Rangeland trend is defined as the direction of change in an existing plant community relative to the potential natural plant community. Further information about the range similarity index and rangeland trend is available in the"National Range and Pasture Handbook,"which is available in local offices of NRCS or on the Internet. The objective in range management is to control grazing so that the plants growing on a site are about the same in kind and amount as the potential natural plant community for that site. Such management generally results in the optimum production of vegetation, control of undesirable brush species, conservation of water, and control of erosion. Sometimes, however, an area with a range similarity index somewhat below the potential meets grazing needs, provides wildlife habitat, and protects soil and water resources. • Reference: United States Department of Agriculture, Natural Resources Conservation Service, National range and pasture handbook. iNatural Resources Web Soil Survey 8/20/2019 Conservation Service National Cooperative Soil Survey Page 2 of 6 Rangeland and Forest Vegetation Classification,Productivity,and Plant Composition---Weld County,Colorado, PAS Permit Application Southern Part Report—Rangeland and Forest Vegetation Classification, Productivity, and Plant Composition Rangeland and Forest Vegetation Classification,Productivity,and Plant Composition—Weld County,Colorado,Southern Part Map unit symbol and soil Ecological Site,Plant Total dry-weight production Characteristic rangeland Compositio name Association,or Habitat or forest understory n Type Favorable Normal year Unfavorable - vegetation Rangeland Forest year year understory Lb/ac Lb/ac Lb/ac Pct dry wt Pct dry wt 35—Loup-Boel loamy sands,0 to 3 percent slopes Loup Sandy Meadow 4,000 3,500 3,000 switchgrass 20 (R067BY029CO) little bluestem 15 reedgrass 10 western wheatgrass 10 sand bluestem 5 slender wheatgrass 5 • yellow Indiangrass 5 Boel Sandy Meadow 4,000 3,500 3,000 switchgrass 20 (R067BY029CO) 41 little bluestem 15 reedgrass 10 western wheatgrass 10 sand bluestem 5 slender wheatgrass 5 IN yellow Indiangrass 5 USDA Natural Resources Web Soil Survey 8/20/2019 Conservation Service National Cooperative Soil Survey Page 3 of 6 Rangeland and Forest Vegetation Classification,Productivity,and Plant Composition---Weld County,Colorado, PAS Permit Application Southern Part Rangeland and Forest Vegetation Classification,Productivity,and Plant Composition—Weld County,Colorado,Southern Part Map unit symbol and soil Ecological Site,Plant Total dry-weight production Characteristic rangeland Compositio name Association,or Habitat or forest understory n Type Favorable Normal year Unfavorable vegetation Rangeland Forest year year understory Lb/ac Lb/ac Lb/ac Pct dry wt Pct dry wt 44—Olney loamy sand,1 to 3 percent slopes Olney Sandy.Plains 1,500 1,100 600 sideoats grama 20 (R067BY024CO) sand dropseed 10 thickspike wheatgrass 10 prairie.sandreed .5 blue grama 45—Olney loamy sand,3 to 5 percent slopes Olney Sandy Plains 1,500 1,100 600 sideoats grama 20 (R067BY024CO) sand dropseed 10 thickspike wheatgrass 10 prairie sandreed 5 blue grama • USDA Natural Resources Web Soil Survey 8/20/2019 ilia Conservation Service National Cooperative Soil Survey Page 4 of 6 Rangeland and Forest Vegetation Classification,Productivity,and Plant Composition---Weld County,Colorado, PAS Permit Application Southern Part Rangeland and Forest Vegetation Classification,Productivity,and,Plant Composition-Weld County,Colorado,Southern Part Map unit symbol and soil Ecological Site,Plant Total dry-weight production Characteristic rangeland Compositio name Association,or Habitat or forest understory n Type Favorable Normal year Unfavorable vegetation Rangeland Forest year year understory Lb/ac Lb/ac Lb/ac Pct dry wt Pct dry wt 49—Osgood sand,0 to 3 percent slopes Osgood Deep Sand 2,200 2,000 1,500 prairie sandreed 15 (R067BY015CO) sand bluestem 15 needleandthread 10 little bluestem: . . 7 other perennial forbs 5 other perennial grasses 5 prairie Junegrass 5 sand dropseed 5 • sand sagebrush 5 • • sideoats grama 5 • other shrubs 3 • blue grama 69—Valent sand,0 to 3 • percent slopes Valent Deep Sand 3,000 1,850 1,200 sand bluestem 30 (R067BY015CO);Sands (North)(PE 16-20) prairie sandreed 20 (R072XA021 KS) switchgrass 15 blue grama 5 little bluestem 5 needleandthread 5 sand dropseed 5 sand sagebrush 5 sedge 5 USDA Natural Resources Web Soil Survey 8/20/2019 Conservation Service National Cooperative Soil Survey Page 5 of 6 Rangeland and Forest Vegetation Classification, Productivity,and Plant Composition—Weld County,Colorado, PAS Permit Application Southern Part Rangeland and Forest Vegetation Classification,Productivity,and Plant Composition—Weld County,Colorado,Southern Part Map unit symbol and soil Ecological Site,Plant Total dry-weight production Characteristic rangeland Compositio name Association,or Habitat or forest understory n Type Favorable Normal year Unfavorable vegetation Rangeland Forest year year understory Lb/ac Lb/ac Lb/ac Pct dry wt Pct dry wt 70—Valent sand,3 to 9 percent slopes Valent Deep Sand 3,000 2,000 1,000 grass 80 (R067BY015CO);Rolling Sands(R072XY109KS) forb 10 shrub 10 84—Playas Playas Closed Upland Depression — — — — (R067BY010CO) 85—Water Water — — — — — Data Source Information Soil Survey Area: Weld County, Colorado, Southern Part Survey Area Data: Version 17, Sep 10, 2018 USDA Natural Resources Web Soil Survey 8/20/2019 Conservation Service National Cooperative Soil Survey Page 6 of 6 EXHIBIT K CLIMATE INFORMATION The subject site area has a high plain, continental climate.

The proposed Project is located approximately 4.5 miles northeast of Keenesburg, Colorado in south-central Weld County, and appears on the Tampa and Klug Ranch, Colorado United States Geological Survey(USGS) 7.5-minute Topographic Quadrangle (Appendix A, Figure 1). The Area of Interest (AOI) includes approximately 640 acres within Guttersen Ranches, LLC property that is predominately utilized as grazing land and for oil and gas development (Appendix A, Figure 2). RETTEW conducted an environmental review that included a desktop assessment and field investigation to identify biological resources within the project area, evaluate potential effects of the Project on these resources, and determine what additional information may be required to determine potential effects. The review included a: 1. Water Assessment 2. Wildlife Assessment 3. Soils Assessment 4. Vegetation Assessment 5. Climate Information. The following sections provide information that will support CSC's Division of Reclamation, Mining and Safety(DRMS) Regular Operation Reclamation Permit Application for the sand mining project. 2.0 WATER ASSESSMENT 2.1 Surface Water Most of the project area consists of arid upland habitat devoid of any surface water. However, one low- gradient drainage runs along the east edge of Section 12.This mapped drainage is identified as Ennis Draw on the USGS Topographic Quadrangle presented in Appendix A, Figure 1, and is depicted with a dashed blue line signifying an intermittent/ephemeral stream.It is also identified on the aerial basemap provided in Appendix A, Figure 2. Areas of ponded water, hydrophytic vegetation, salt covered and/or sparsely vegetated depressions,and saturated soils were observed within portions of this drainage during the field investigation. Photographs of these features are provided in Appendix B. Although Ennis Draw is depicted as a continuous dashed line on the USGS topographic map through all of Section 12,field crews did not observe evidence of a stream channel or a defined bed and bank through the entire drainage. Some portions were completely vegetated. It appeared that ponded surface water remains within portions of the drainage year-round, and in other portions only seasonally. No flowing water was observed anywhere in Ennis Draw. Photographs of the drainage are provided in Appendix B and identified on the aerial basemap provided in Appendix A, Figure 2. National Wetlands Inventory (NWI) mapped wetlands are located within and adjacent to Ennis Draw (Appendix A, Figure 2). NWI maps are derived from aerial photo interpretation, are designed for general planning purposes only,and typically do not show all the wetland or watercourse resources within any given area. Field crews investigated some of these areas to confirm the presence of wetlands. Wetland presence/absence procedures followed the protocol described in the 2012 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Great Plains Region, Version 2.0. This approach recognizes the 1 Keenesburg Project RETTEW Project No.114782000 Colorado Sand Company LLC April2019 three parameters of hydrology, vegetation, and soils to identify wetlands. A linear palustrine emergent (PEM)wetland(Wetland 1)was documented within the drainage at Sample Point W-1,and is depicted on Appendix A,Figure 2. Hydric soils were observed in several soil test pits that were dug within Wetland 1 and throughout other portions of the drainage. A Wetland Determination Data Form was completed to document the conditions at Sample Point W-1 and is provided in Appendix C. Photographs of the wetland are provided in Photographs 17 and 18 in Appendix B. Additional NWI mapped wetlands are located in the southeast quarter of Section 12 (Appendix A, Figure 2). This area was not visited during the field investigation. Wetlands were not delineated during the field investigation. Wetlands and streams are regulated by the United States Army Corps of Engineers (USACE). 2.2 Ground Water The project area falls within the South Platte River Valley. Surficial aquifers here generally contain the shallowest ground water and consist of Quaternary deposits of alluvial gravel, sand, silt, and clay or Quaternary deposits of eolian sand and silt (USGS, 1995). The stream valley of the South Platte River is eroded into the surface of the underlying bedrock formations. The sedimentary rocks that underlie the alluvium of the South Platte River Valley on the plains generally consist of shale and sandstone of Cretaceous age that are easily eroded to form broad, gently sloping valleys that contain meandering streams and moderately thick alluvium(USGS,1995).The surficial aquifer of the South Platte River ranges in thickness from about 20 to 200 feet and ranges in width from about 1 to 15 miles (USGS, 1995). The project area is within the Denver Basin aquifer system,which underlies an area of about 7,000 square miles that extends south from Greeley to near Colorado Springs (USGS, 1995). The Denver Basin aquifer system is not well connected to other major aquifers in the area,and the surficial aquifer along the South Platte River Valley is the only other major aquifer near the Denver Basin (USGS, 1995). Shallow, discontinuous surficial aquifers overlie parts of the Denver Basin aquifer system, primarily along small streams that extend south from the South Platte River.The Denver Basin aquifer system consists of four aquifers that are present in five geologic formations (Illustration 1).The project area is located along the borders of the Arapahoe and Laramie-Fox Hills aquifers. Unconfined and confined conditions are present in the bedrock aquifers of the Denver Basin.The aquifers are unconfined primarily near outcrops where the water table may be at relatively shallow depths. The aquifers are confined in deeper parts of the basin where confining units restrict vertical movement of water and cause water levels in wells to rise above the top of the aquifer(USGS, 1995). Depth to water in wells completed in the north half of the Denver Basin aquifer ranges from 0 to 250 feet. Water in the Denver Basin aquifer system generally has a small dissolved-solids concentration and, in most areas, meets drinking-water regulations established by the U.S. Environmental Protection Agency for public water supplies (USGS, 1995). The Division of Water Resources (DWR) online web viewer was used to identify water wells within and adjacent to the project area. Three DWR permitted water wells are depicted on Appendix A, Figure 2. The DWR water well (permit No. 75237), located in Section 1 outside the AOI to the north, is currently permitted for watering livestock. Per DWR,there is a high probability that this well can be re-permitted for drinking water and sanitation uses with limits of 15 gallons per minute (gpm) and 1/3 acre feet per year.The water well in Section 12(permit No.159505)and the water well in Section 7(permit No.75234), outside the AOI to the east,were both identified as being used for watering livestock. 2 Keenesburg Project RE7TEW Project No. 114782000 Colorado Sand Company LLC April 2019 W _ - o B, 1ob� . — - 4 . 014- - AN SOULQ .

The assessment included a desktop review and a field investigation . Species considered included those listed by the U . S . Fish and Wildlife Service ( USFWS ) as threatened , endangered , proposed , or candidate ; State of Colorado as threatened , endangered , or species of special concern ; and migratory birds . Species activity data from Colorado Parks and Wildlife ( CPW ) was reviewed as part of the assessment . Results of the desktop and field evaluations are summarized below . 3 . 1 Regulations 3 . 1 . 1 Federal The Endangered Species Act ( ESA) protects threatened and endangered species and their habitats and requires consultation with and concurrence by the USFWS for projects that have the potential to affect federally listed species . The ESA makes it unlawful to take a listed animal without a permit . Take is defined as, " . . . to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect or attempt to engage in any such conduct. " The Migratory Bird Treaty Act ( MBTA ) makes it illegal to take, possess, import, export, transport, sell, purchase, or offer for sale, purchase , any migratory bird , or the parts, nests , or eggs of such a bird except under the terms of a valid federal permit . Migratory bird species protected by the Act are listed in 50 CFR 10 . 13 . The Bald and Golden Eagle Protection Act ( BGEPA ) provides additional protections for bald or golden eagles . 3 . 1 . 2 State Colorado Parks and Wildlife ( CPW ) maintains a list of threatened and endangered species in the state of Colorado . Per the regulations contained in Title 33 Parks and Wildlife — Wildlife Article 1 (Wildlife — General 3 Keenesburg Project RETTEW Project No.114782000 Colorado Sand Company LLC April2019 Provisions) and Article 2 (Nongame and Endangered Species Conservation) of the Colorado Revised Statutes, "...it is unlawful for any person to take, possess, transport, export, process, sell or offer for sale or ship and for any common or contract carrier to knowingly transport or receive for shipment any species or subspecies of wildlife appearing on the list of wildlife indigenous to this state determined to be endangered or threatened within the state." CPW also maintains a list of state special concern species; however,these species are not protected under state law. 3.2 Desktop Assessment 3.2.1 Habitat The project area consists of grasslands habitat with gently rolling topography.Vegetation is composed of various grasses, yucca, and sand sagebrush. Trees are largely absent within the project area. Elevations across the site range from 4,950-4,600 feet and mean annual precipitation ranges from 10 -18 inches (Armstrong, 1992). Soils contain a high percentage of sand and are mostly well-drained. The majority of the project area is a homogenous landscape,although one drainage(Ennis Draw) runs from south to north in the western half of the site.Areas of ponded water,dense vegetation and adjacent wetland habitat can be found within this drainage. 3.2.2 Federal Species A desktop study was conducted using the U.S. Fish and Wildlife (USFWS) Information, Planning, and Conservation(IPaC)System to identify federally listed species potentially occurring within the project area or that may be affected by the proposed project (IPaC, USFWS 2018). Nine federally listed threatened, endangered or candidate species were identified (Appendix D).Table 3.1 evaluates the potential for each of the species to occur within the project area. Table 3.1-Federally Listed Species Potential Common Name Scientific Name Status Habitat Occurrence within Site2 Birds Least Tern' Sterna antillarum Endangered Sandbars along rivers, lake Not Likely shorelines, only known to occur in southern Colorado Mexican Spotted Owl Strix occidentalis Threatened Old growth forests Not Likely lucida Piping Plover' Charadrius Threatened Sand/gravel beaches Not Likely melodus adjacent to alkali wetlands and sandbars of major rivers Whooping Crane' Grus americana Endangered Wetlands,wet meadows, Not Likely(last areas around rivers and wild bird in CO agricultural fields died in 2002) Table continues on next page 4 Keenesburg Project RETTEW Project No.114782000 Colorado Sand Company LLC April2019 Fishes Pallid Sturgeon' Scaphirhynchus Endangered Large rivers None albus Flowering Plants Colorado Butterfly Gaura Threatened Alluvial soils on active Not Likely Plant neomexicana var. floodplains, depressions, coloradensis wide, meandering stream channels Ute Ladies'-tresses Spiranthes Threatened Riparian edges, gravel Not Likely diluvialis bars,wet meadows along perennial streams Western Prairie Platanthera Threatened Unplowed, calcareous Not Likely Fringed Orchid' praeclara prairies and sedge meadows Mammals Preble's Meadow Zapus hudsonius Threatened Densely vegetated,shrub- Not Likely Jumping Mouse preblei dominated riparian (streamside) areas and immediately adjacent undisturbed grasslands 'Platte River Recovery Implementation Program Species 'The potential for occurrence is based on desktop and field assessments.Consultation with USFWS Colorado Ecological Services Field Office will be required to confirm findings. Five of the species identified by IPaC (Least tern, Pallid sturgeon, Piping plover, Western prairie fringed orchid, and Whooping crane) are USFWS Platte River Species. These species should be considered if a water-related activity or use is proposed within the North Platte,South Platte or Laramie River Basins that may lead to downstream depletions of the river system in Nebraska. Because the project area is in the South Platte River Basin, consultation with the USFWS Colorado Ecological Services Field Office is recommended to determine if impacts are anticipated, and if mitigation would be required. The IPaC report generated for the project also identified one additional migratory bird species that is protected under the Migratory Bird Treaty Act(MBTA)and Bald and Golden Eagle Protection Act(BGEPA) and has limited potential to occur at the site. The Golden Eagle (Aquila chrysaetos) inhabits grasslands and forest habitat and often nests on cliffs or in large trees that offer unobstructed views of their surroundings. Cliffs and large trees are absent from the project area, making it unlikely that the project area would provide suitable habitat for this species. 3.2.3 State Species RETTEW reviewed CPW All Species Activity Mapping GIS data to identify species with ranges that overlap the project area(CPW,2018).CPW habitat suitability descriptions were compared with data from the field investigation and aerial mapping to determine which species have the potential to occur within the project area.Table 3.2 identifies the evaluated species and lists the potential for each to occur within the project area. 5 Keenesburg Project RETTEW Project No.114782000 Colorado Sand Company LLC April2019 Table 3.2-State Listed Species Potential Common Name Scientific Name Status' Habitat Occurrence within Site Birds Burrowing Owl Athene cunicularia MBTA, Shortgrass prairie in or adjacent Possible ST to prairie dog towns Mountain Plover Charadrius Prairie grasslands, shortgrass Possible M A montanus SC prairie grazed by cattle or prairie dogs Mammals Black-tailed Cynomys Grasslands, shortgrass prairie, Possible SC Prairie Dog ludovianus desert grasslands Plains Pocket (Geomys bursarius) Upland areas of eastern plains in Likely Gopher deep sandy soils 1MBTA—Protected under Migratory Bird Treaty Act 2The potential for occurrence is based on desktop and field assessments.Comments from CPW will be required to confirm findings. SC—State Special Concern ST—State Threatened RETTEW also coordinated with the CPW District Wildlife Manager on January 7, 2019, regarding species of concern in the project area to obtain additional information. The District Manager stated that CPW generally requests a 30-day window for reviewing land use proposals, and that he could provide comments once CPW receives the Use by Special Review (USR) notice from Weld County Planning Department for the project. As of the date of this report, no response from CPW has been received. 3.3 Field Investigation The field investigation was conducted by qualified biologists on December 19 and 20,2018. Field crews were escorted through Guttersen Ranch by the ranch caretaker. 3.3.1 Methods Field crews completed vehicle and pedestrian surveys of the project area using previously prepared field maps and Global Positioning System (GPS) units which were utilized to navigate to the center of each quarter- section within the project area. Field crews navigated to previously identified sample point locations at the centroid of each quarter-section. Sample Point Data Forms were completed at each sample point and included location,vegetation,soil,wildlife observations, and general habitat information (Appendix C).This data was used to characterize conditions present within the project area.Sample point locations are identified on the aerial basemap (Appendix A, Figure 2). Photographs were taken at each sample point and of any relevant findings and are provided in Appendix B. Ranch roads were utilized to get as close as possible to each pre-determined sample point location,then field crews walked the remainder of the way. Final sample point locations were chosen to be representative of surrounding habitat. The portion of the project area investigated during the field effort was limited to the areas around each sample point and the most direct routes between each location. 6 Keenesburg Project RETTEW Project No.114782000 Colorado Sand Company LLC April2019 3.3.2 Results The majority of the project area consists of moderately to heavily grazed pasture with a significant amount of sandy bare ground. The only wildlife observations included a red-tailed hawk soaring overhead and jackrabbits near two of the sample points. Rodent burrows and tracks were observed scattered throughout the project area. No suitable trees for nesting raptors were noted. No evidence of prairie dogs or prairie dog burrows were observed. No migratory bird nests,dens,or other wildlife signs were observed. The shallow drainage located along the east side of Section 12,that is visible on aerial imagery(Appendix A, Figure 2), contains wetlands and ponded water in areas. These wetland areas contained dense vegetation that was not present in upland portions of the project area, and likely provide water and habitat for passing birds,wildlife,and cattle. 3.4 Conclusions The following wildlife species were identified as having the potential to occur in the project area: • Burrowing owl • Mountain plover • Black-tailed prairie dog • Northern pocket gopher. These species were selected based on their range and general habitat requirements. No known occurrences of these species within the project area were identified during the desktop review or the field investigation. The burrowing owl(Athene cunicularia) is federally protected by the MBTA and is also listed as threatened by the State of Colorado. Burrowing owls prefer to nest in shortgrass prairie,often in or adjacent to prairie dog towns. They nest and live in underground burrows created by prairie dogs, ground squirrels and badgers.Although no prairie dog towns were observed within the project area,the field investigation was limited in scope and field crews did not survey the entire project area. Therefore, there is potential for burrowing owl habitat to exist within the project area. The mountain plover(Charadrius montanus) is federally protected by the MBTA and also as State Special Concern Species by the State of Colorado. Mountain plovers inhabit prairie grasslands, arid plains and fields. Nesting plovers choose shortgrass prairies grazed by prairie dog and cattle,and overgrazed tallgrass and fallow fields. No plovers or nests were observed during the limited field investigation; however, suitable habitat may exist within the project area. The Black-tailed prairie dog(Cynomys ludovianus)is a State of Colorado Special Concern Species but is not protected under state law. No prairie dogs or prairie dog towns were observed during the site investigation. The sandy soils found throughout the project area may not provide quality or suitable habitat for prairie dogs. The Plains pocket gopher (Thomomys talpoides macrotis) is the most likely of the four Colorado pocket gopher species to be found in the project area because it prefers deep sandy and silty soils. Pocket gophers reduce productivity of portions of native grasslands by 20 to 50 percent (CSU, 2016). Evidence of small mammal burrows was observed at several locations across the project area during the site investigation. The Plains pocket gopher is not listed by the State of Colorado or protected under state law. 7 Keenesburg Project RE7TEW Project No.114782000 Colorado Sand Company LLC April2019 4.0 SOIL ASSESSMENT 4.1 Topography and Drainage The majority of the project area is comprised of gently rolling grazed rangeland. Review of the Tampa and Klug Ranch, Colorado United States Geological Survey (USGS) 7.5-minute Topographic Quadrangle (Appendix A, Figure 1), shows an elevation between 4,950 -4, 600 feet above mean sea level. Drainage from the project area generally flows north from the site. 4.2 Soil Survey Mapping depicting soil unit boundaries within the project area is provided in Appendix A, Figure 3. A U.S. Department of Agriculture (USDA) Natural Resources Conservation Service Custom Soil Resource Report is provided in Appendix E.A summary of the mapped soils is also provided in Table 4.1.Most of the project area consisted of sandy soils, although Loup-Boel loamy sands, 0-3% slopes occur in swales and drainageways in landform settings and are mapped within the drainage running through the east portion of Section 12. Site specific soil information is also contained on the Sample Point Data Forms included in Appendix C.

Detailed bore logs are provided in Appendix F. Borings were completed to determine soil profiles, moisture content,groundwater depths, and bedrock depths. 5.0 VEGETATION During the field investigation, vegetation data was collected at the sample points depicted on the aerial basemap provided in Appendix A, Figure 2, and recorded on sample data forms provided in Appendix C. Vegetation across the site is primarily composed of various grasses, prickly pear, and sand sagebrush. Trees are largely absent within the project area,with the exception of a small grove of Russian olive trees in the far southeast corner of the section. The majority of project area consists of grazed grasslands containing patches of sagebrush and a significant amount of bare ground (30 to 70 percent).Shrub cover ranged from 0 to 30 percent cover. Sample points 1-4 were located within this grazed upland habitat. The landscape generally appears as a relatively homogenous landscape. However, one drainage (Ennis Draw) runs through the west half of the project area. Vegetation within portions of this drainage, especially those areas containing ponded water and saturated soils, was distinctly different from the surrounding upland areas and was documented by sample point W1.Wetlands were documented within Ennis Draw at this sample point. A summary of the plant species identified at each sample point is provided in Table 5.1 below. Root depth at each sample point was approximately six inches deep. Table 5.1-Vegetation species at each sample point. Sample Point Species 1 I 2 ] 3 I 4 W1 Shrub Stratum Sand sagebrush (Oligosporus filifolius) • • Twistspine prickly pear(Opuntia • macrorhiza) Herb Stratum Blue grama grass (Condrosum gracile) • Water sedge(Carex aquatilis) • Cheatgrass(Bromus tectorum) • • • • Intermediate wheatgrass (Thinopyrum • intermedium) Western wheatgrass(Pascopyrum smith ii) • • Little bluestem (Schizachyrium scoparium) • Common threesquare(Scoenoplectus • pungens) Saltgrass (Distichlis spicata) • • Indian ricegrass(Oryzopsis hymenoides) • • Additional information for each sample point can be found on the sample point data forms contained in Appendix B. 9 Keenesburg Project RETTEW Project No.114782000 Colorado Sand Company LLC April2019 6.0 CLIMATE The climate over the plains of eastern Colorado generally has abundant sunshine, moderate to high wind, low relative humidity, a large daily range in temperature, and little precipitation.About 60 to 80 percent of the annual precipitation falls during April to September, primarily from thunderstorms (USGS, 1995). The region surrounding the project area averages an annual high temperature of 68.8°F and an annual low temperature of 36.7°F. Summer temperatures during July and August average 94°F and 91°F, respectively. Winter temperatures during January and February average 46°F and 50°F, respectively.The average annual temperature is 52.75°F. Average annual precipitation is 14.67 inches. Average annual snowfall is 41 inches. May is the rainiest month,averaging 2.4 inches of precipitation. March receives the most snowfall on average,with 8 inches,followed by November with 7 inches. 10 Keenesburg Project RETTEW Project No.114782000 Colorado Sand Company LLC April 2019 8.0 LITERATURE CITED Cowardin, L.M., V.

The species list fulfills the requirements of the U . S . Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973 , as amended ( 16 U . S .C . 1531 et seq. ) . New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402 . 12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired . The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information . An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list. The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved . Under sections 7(a)( 1 ) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq. ) , Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered 04/02/2019 Event Code:06E24000-2019-E-02048 2 species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat. A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts)that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act(42 U.S.C. 4332(2) (c)). For projects other than major construction activities, the Service suggests that a biological evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12. If a Federal agency determines, based on the Biological Assessment or biological evaluation,that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species,proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at: http://vvww.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act(16 U.S.C. 668 et seq.), and projects affecting these species may require development of an eagle conservation plan(http://www.fws.gov/windenergy/ eagle_guidance.html).Additionally,wind energy projects should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and bats. Guidance for minimizing impacts to migratory birds for projects including communications towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http:// www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm; http:// www.towerkill.com; and http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/ comtow.html.

Please make sure you read and understand the 04/02/2019 Event Code: 06E24000-2019-E-02048 2 FAQ "Proper Interpretation and Use of Your Migratory Bird Report" before using or attempting to interpret this report. Probability of Presence(u) Each green bar represents the bird's relative probability of presence in the 10km grid cell(s)your project overlaps during a particular week of the year. (A year is represented as 12 4-week months.)A taller bar indicates a higher probability of species presence. The survey effort(see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high. How is the probability of presence score calculated?The calculation is done in three steps: 1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them,the probability of presence of the Spotted Towhee in week 12 is 0.25. 2. To properly present the pattern of presence across the year,the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 =0.2. 3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score. Breeding Season (a) Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area. Survey Effort(I) Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s)your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys. No Data (—) A week is marked as having no data if there were no survey events for that week. Survey Timeframe Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas off the Atlantic coast,where bird returns are based on all years of available data, since data in these areas is currently much more sparse. 04/02/2019 Event Code: 06E24000-2019-E-02048 3 ■ probability of presence breeding season I survey effort — no data SPECIES JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC Golden Eagle — ---- 1inell rumr ---- ---- ------ --- ---- --- ---- -- ---- — --- — ----- BCC - BCR ��t4' Sl 0400001-4 001* Additional information can be found using the following links : • Birds of Conservation Concern http ://www.fws .gov/birds/management/managed-species/ birds-of-conservation-concern .php • Measures for avoiding and minimizing impacts to birds http ://www.fws.gov/birds/ management/project-assessment-tools-and-guidance/ conservation-measures.php • Nationwide conservation measures for birds http ://www.fws. gov/migratorybirds/pdf/ management/nationwidestandardconservationmeasures .pdf Migratory Birds FAQ Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds. Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure . To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures and/or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site . What does IPaC use to generate the migratory birds potentially occurring in my specified location ? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location . The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN) . The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identified as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to offshore activities or development. 04/02/2019 Event Code: 06E24000-2019-E-02048 4 Again,the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area,please visit the E-bird Explore Data Tool. What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specified location? The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network(AKN). This data is derived from a growing collection of survey. banding. and citizen science datasets . Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link. How do I know if a bird is breeding,wintering, migrating or present year-round in my project area? To see what part of a particular bird's range your project area falls within(i.e. breeding, wintering, migrating or year-round), you may refer to the following resources: The Cornell Lab of Ornithology All About Birds Bird Guide, or(if you are unsuccessful in locating the bird of interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area,there may be nests present at some point within the timeframe specified. If"Breeds elsewhere" is indicated, then the bird likely does not breed in your project area. What are the levels of concern for migratory birds? Migratory birds delivered through IPaC fall into the following distinct categories of concern: 1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC)that are of concern throughout their range anywhere within the USA(including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands); 2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and 3. "Non-BCC -Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or(for non-eagles) potential susceptibilities in offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing). Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular,to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics. Details about birds that are potentially affected by offshore projects 04/02/2019 Event Code:06E24000-2019-E-02048 5 For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area off the Atlantic Coast,please visit the Northeast Ocean Data Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to you in your project review.Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage. Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring. What if I have eagles on my list? If your project has the potential to disturb or kill eagles,you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur. Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area,please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my specified location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cell(s)that overlap your project; not your exact project footprint. On the graphs provided,please also look carefully at the survey effort(indicated by the black vertical bar) and for the existence of the"no data" indicator(a red horizontal bar).A high survey effort is the key component. If the survey effort is high,then the probability of presence score can be viewed as more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area,when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn more about conservation measures,visit the FAQ "Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds"at the bottom of your migratory bird trust resources page. 04/02/2019 Event Code: 06E24000-2019-E-02048 1 Wetlands Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes.

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.nres.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=nrcs142p2_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.

They include a 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 characteristics 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 5 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 6 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. 7 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 displayed on the map.Also presented are various metadata about data used to produce the map, and a description of each soil map unit. 8 Custom Soil Resource Report Soil Map (CSC Keenesburg Project) f"l N ° ° Ig V O 541000 541300 541600 541900 542200 542500 542800 543100 543400 543700 544000 544300 40° 9' 46" N ; . - • f r +q.y ° . t' �+�+ �° 9, X11 N a:: '[ t ..S • - ..

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 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 11 Custom Soil Resource Report 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. 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. 12 Custom Soil Resource Report Weld County, Colorado, Southern Part 35—Loup-Boel loamy sands, 0 to 3 percent slopes Map Unit Setting National map unit symbol: 362f Elevation: 4,550 to 4,750 feet Mean annual precipitation: 11 to 15 inches Mean annual air temperature: 46 to 52 degrees F Frost-free period: 130 to 180 days Farmland classification: Not prime farmland Map Unit Composition Loup and similar soils: 55 percent Boel and similar soils: 35 percent Minor components: 10 percent Estimates are based on observations, descriptions, and transects of the mapunit.

GERKIN and HELENA A. GERKIN Keenesburg Project_Limited Impact 110 Application_May 24,2019 L-47 MEMORANDUM To: Timothy McCarthy,PE—CSC Permitting Contact From: James M.Beck,PE Subject: Evaluation of Risk and Damage Potential—Gerkin Fence Lines Date: May 22,2019 You have indicated that,to date,you have been unable to secure a signed"Structure Agreement" (as per the requirements of DRMS Rule 6.3.12: Permanent Man-Made Structures) from neighboring property owner(s) Vince C. and Helena A. Gerkin. Research completed during preparation of the Keenesburg Project permit application has more specifically identified the Gerkins as owner(s) of two (2) fence lines located generally to the south(and within 200 feet)of the designated Colorado Sand Company LLC(CSC) proposed Keenesburg Project's"affected area"(otherwise defined as the"Permit Area",and as depicted in Exhibit A-3 of the Application). Regulatory Requirement: Rule 6.3.12 requires that in cases "where the mining operation will adversely affect the stability of any significant, valuable and permanent man-made structure located within two hundred feet of the affected land, the Applicant shall either(in part): (a) provide a notarized agreement between the Applicant and the Person(s)having an interest in the structure, that the Applicant is to provide compensation for any damage to the structure;or, (b) where such an agreement cannot be reached, the Applicant shall provide an appropriate engineering evaluation that demonstrates that such structure shall not be damaged by activities occurring at the mining operation. Subject Structure(s): Based on Figure A-3 and field observations noted during a site visit completed by the undersigned on March 20,2019,the subject fence line(s)can be described as: A four-strand barbed wire fence with wooden posts extending (1) in a generally west to east direction approximately 50 feet south of and roughly parallel to the Section 12 south line;and,(2) in a general north to south direction,approximately 50 feet east of and generally parallel to Weld County Road 59. The respective fence lines join at an approximate right angle at a point approximately coincident with(but roughly 50 feet south of)the common corner of Sections 11, 12, 13,and 14;T2 N;R64W; Sixth Principal Meridian. Damage Risk Potential:Based on my understanding of the proposed Keenesburg Project and the location and characteristics of the subject structure,there appears to be only three(3)readily identifiable(potential) scenarios wherein a risk of damage to the fence structure could be introduced,as follows: (1) ,Slope stability and/or sloughing of the main mining pit sidewalls:Based on project plans,at its closest,the proposed main mine pit will be situated some 250 feet distant from the west to east fence line. Maximum pit depth is anticipated to be on the order of 25-to 30-feet(more or less) 1 Keenesburg Project Limited Impact 110 Application_May 24,2019 L-48 below ground surface and sidewall slopes(internal to the pit perimeter)are to be maintained at a gradient of 3H:1 V(e.g.,3 feet horizontal to 1 foot vertical). Given that the proposed sidewall gradient is at or near the(sand)material's anticipated natural angle of repose,it is my opinion that there is minimal potential for significant sloughing and/or further unplanned creep or advancement of the south pit wall (crest) to occur in the direction of the subject structure. Further to this, the proposed plan indicates the presence of an intervening perimeter road(also within the Permit Area)which would serve to support mining operations. In the event this road were to be compromised,such would necessitate the operator to immediately invoke mitigating measures in order to sustain mining activities, thereby eliminating the potential for further advancement in the direction of the structure. Given the nature of the(sand)material and the provisions incorporated into the project plans, it is my opinion that the likelihood of pit wall sloughing(to the extent such may occur)resulting in a southward-moving lateral advancement of the excavation, toward the subject structure a distance sufficient to challenge the integrity of the structure,is virtually nil. (2) Ground vibration ejects: Based on project plans, there will be no blasting occurring in conjunction with mining activities. Blasting effects can be a potential concern with respect to structural damage potential, however, the use of only traditional excavating equipment at the Keenesburg Project eliminates that potential. Further to this,the nature of the(sand)material is such that ripping will not be required; all indications are that mining will be accomplished via the use of front end loaders and/or hydraulic excavators. Thus, the only source of ground vibration would be highly localized and associated with the operation of those types of heavy equipment in the mining operation. The heavy equipment will be largely operating at locations in excess of the 250 feet distance cited above(i.e.,the"centroid"of the pit will be at a distance of approximately 350 feet from the structure). In addition to the excavating activity, routine truck traffic will enter(empty) and exit (loaded) the project site at the gated entry to Guttersen Ranches LLC) located approximately 80 feet to the north of the subject structure;however,this ingress/egress location is exterior to the Permit Area,as defined. Any significant vibration effects introduced by mining activities will, in my opinion,be fully dissipated and/or attenuated well distant from the subject structure(s); and,the types of trucks accessing the site will not be significantly different from those currently routinely passing the location in conjunction with the Waste Management, Inc. Buffalo Ridge Landfill operations and/or the other industrial facilities further north on the (private) Weld County Road 59 extension. There is no evidence to suggest that the current/ongoing truck traffic has to date adversely affected,or will in the future adversely affect the subject structure(s). (3) Vehicular-induced (collision) damage: As indicated above, based on project plans, site ingress/egress will be accomplished at a point approximately 80 feet north of the subject structure(but at a distance of 200-plus feet from the Permit Area boundary). There is also an 2 Keenesburg Project_Limited Impact 110 Application_May 24,2019 L-49 existing turnout/staging area present further to the west(at an estimated distance of 25-to 30- feet of the subject structure at that location)that may be utilized by truck traffic. Nevertheless, the subject fence structure is situated some 50 feet east of Weld County Road 59, and with an intervening minor drainage swale. Movement of heavy truck traffic(and other types of vehicles) in and around the site entrance and the proximal turnout/staging area does,in my opinion,appear to present a potential,albeit limited,for vehicular-induced(collision)damage. The gated entry, separation distance,and existing speed limits on Weld County Road 59 and the ranch service road,respectively, should serve to minimize this potential. Further to this, all vehicles accessing the site are required,by law,to be appropriately licensed and insured,to include collision damage liability coverage in amounts well in excess of the probable replacement value for what would likely be a limited length of fence line either damaged or destroyed as a result of a vehicular collision with the structure,in the event such were to occur. Based on the foregoing, it is my opinion that the presence of,and activities associated with, the proposed Keenesburg Project do not pose significant or meaningful risk of damage potential with respect to the above-described subject permanent structure(s)proximal to the proposed Permit Area.
