Ex Mining Plan Map J-2 Contracting Company O 0 0 J&T CONSULTING Job # 18114 Date 4/4/19 Drawn By Designed By Checked By File Scale BDC TPY JCY JT-Mining Sheet: 5 Of: EXHIBIT D Mining Plan Mining Limits J-2 Contracting proposes to mine in the land located in the north 1/2 of section 12, and the southwest 1/4 of northeast corner of section 11, township 5 north, range 65 west of the 6th p.m., and the south 1/2 section of section 1, township 5 north, range 65 west of the 6th p.m., Weld County, Colorado. The proposed mining site is located approximately 2 miles north and 2 miles west of the Town of Kersey, and approximately 2 miles north of State Highway 34. The South Platte River is approximately 600 feet south of the site on the west side of the permit boundary and 200 feet south and east of the site on the east side of the permit boundary. The Cache La Poudre River is adjacent to the north side of the permit boundary. The Weld County Parkway is immediately adjacent to the west side of the permit boundary. Access to the site will be located at the southwest corner of the permit boundary off of the Weld County Parkway. The dominant land use surrounding the property is agricultural. An aggregate processing plant area and a concrete and asphalt batch plant area will be located within the mining area as shown on the Mining Plan Map. These areas will contain stockpiles, portable equipment, storage bins, and silos as necessary to support the plant operations. Designated locations for concrete truck washout and excess concrete product dumping will be provided to ensure that waste materials are recycled and kept from entering the stormwater flows on the site. The concrete truck washout area will be a 30 foot by 20 foot three cell concrete structure. Concrete trucks will wash the residual product from their mixing drums and chutes into the first cell of the structure. The first cell spills into the second cell, which spills into the third cell. This allows the aggregate and suspended fines to settle into the cells over time. The water and settled material in the three cells is then removed as required and recycled into the concrete batch plant. Generally, the cells are cleaned on a weekly schedule. The excess product dumping area will be approximately 50 feet by 100 feet and have an exterior berm to limit the migration of stormwater flows to and from the surrounding areas. Excess product that is deposited in this area will be allowed to cure for approximately 90 days until it becomes inert. It will then be crushed and recycled. All local, State, and Federal rules and regulations will be followed for the storage and handling of any fuel, asphalt, cement, flyash, and admixtures required for the batching facilities. The permit boundary will encompass approximately 228.02 acres with approximately 190.37 acres being mined. The remaining area will consist of setbacks, road and utility right-of-ways, equipment storage, and plant site access. Various setbacks from adjacent roads, adjacent structures, and oil and gas infrastructure will be maintained as mining occurs. All setbacks specified in the surface use agreements with the oil/gas companies will be followed. Attached are draft surface use agreements with the pertinent oil/gas companies. The final executed agreements are expected to be obtained in the near future and will be forwarded to the Division when they are available. A minimum 200 foot J&T Consulting, Inc. J-2 Contracting Company DPG Mining Site DRMS 112 Permit Application setback from any existing oil/gas facility will be maintained until that time. See Exhibit C, Mining Plan Map, and the Slope Stability Report for the mining limit configuration and information on setbacks and their locations. Products Sand and gravel will be the primary product produced from the DPG Mining site. The principal intended use for the sand and gravel is for road base and construction aggregates. Subsurface drilling and testing have verified that the DPG Mining site property contains a significant commercial deposit of sand and gravel. The depth of interbedded sandy clays and clayey to silty sands at the surface range from 3 to 12 feet. The thickness of the aggregate material ranges from 67 to 102 feet where bedrock contact occurs. Mining Methods The deposit will be dry mined and a slurry wall will be constructed around the perimeter of the mining area for Phase 1. Phase 2, 3, 4, and 5 will not be opened until the slurry wall is constructed around each phase prior to mining each phase. Design specifications for the slurry wall and quality control procedures used during construction will ensure that the reclaimed reservoir meets State Engineer's Office (SEO) performance standards. Dewatering trenches will be excavated around the perimeter of each mining area in Phases 1 — 5 prior to mining operations commencing. The depth of the ditches will vary as the mining progresses deeper into the alluvium in order to maintain the groundwater level below the active mining bottom surface, and therefore minimize the exposed groundwater surface area. The dewatering ditches will flow to a collection pond, from which the water will be pumped into a ditch, which traverses the mining phases and eventually discharged into the Cache La Poudre River. The equipment and facilities may include, but are not limited to the following: Processing Equipment Screens, crusher, conveyors, stackers, and other miscellaneous processing equipment. Earth Moving Equipment Dozers, loaders, scrapers, excavators, and compactors will be used for mining and earth moving operations. Miscellaneous Equipment Dewatering pumps, electrical trailer, generator trailer, small portable generators and watering trucks will be used as needed. As mining progresses, topsoil and overburden will be stripped to expose the aggregate product below. All soil and overburden material will be used on -site for reclamation; so long-term stockpiling of these materials is not anticipated. Overburden stockpiles will be located within the proposed mining area. The stockpiles will be placed parallel to the floodplain to mitigate impacts to the floodplain. Mining of the aggregate will progress down to the underlying bedrock. Since reclamation will occur concurrently with mining, it is not anticipated that overburden material will be stockpiled long-term prior to use in production of road base and potentially backfilling of pit areas that are not lined with a slurry wall. During mining the mining face will have a 3H:1V slope to bedrock or J&T Consulting, Inc. J-2 Contracting Company DPG Mining Site DRMS 112 Permit Application the bottom of the future reclaimed reservoir. The processed aggregate material will be temporarily stockpiled near the portable processing plant. All local, State, and Federal rules and regulations will be followed for the storage and handling of any fuel for the facilities. Topsoil Handling Plan As stated previously the topsoil will be stripped to expose the aggregate product underlying the topsoil. The topsoil will be stripped using scrapers and stockpiled in the topsoil stockpile as depicted in Exhibit C. The volume of topsoil for all the mining phases is approximately 306,000 cubic yards. The depth of the topsoil is approximately twelve inches over the majority of the mining area. The topsoil will be stripped and stockpiled during each phase of mining where topsoil will only be removed for Phase 1, Phase 2, Phase 3, Phase 4, and Phase 5 as they are going to be mined. The height of the topsoil stockpile will be approximately 15 feet. Mine Phasing J-2 Contracting anticipates mining and reclaiming the DPG Mining site in 5 phases, progressing through the phases as shown on the Mining Plan Map. The overall time required to complete the mining and reclamation is estimated to be 30 years. Maximum production is expected to be 750,000 tons per year. However, it is possible that due to demand fluctuations, mining could progress slower than anticipated and additional time may be required for mining and reclamation of the site. J-2 Contracting Company will mine down to an elevation of 4523 in Phase 1 of the mining plan encompassing a total of 24.57 acres of the mining limits and groundwater will be exposed. A slurry wall will be constructed around Phase 1. It is expected that a maximum of 2 phases will be disturbed at any given time, and if more are disturbed J-2 Contracting Company will provide notification to DRMS and financial warranty for each phase prior to opening or disturbing. The mining will progress in each phase beginning at the outer edge of the phase where material will be moved toward the interior of the phase such that a 3H:1V mining slope can be established on the exterior of the phase and then transition to a 3H:1V slope. The mining slope will be established for the entire perimeter of the phase in 3 to 6 feet intervals. In Phases 1 — 5 a dewatering trench around the perimeter will be placed at the toe of the 3H:1V or 3H:1V mining slope. As the phase is mined deeper the dewatering trench will be lowered and moved laterally along the 3H:1V and then the 3H:1V mining slope toward the center of that phase. Once the interior footprint becomes small enough where the 3H:1V mining slopes from three to four sides are encroaching upon the portable plant and haul roads another phase will be opened to continue mining. Dewatering Dewatering trenches will be placed along the perimeter of each mining area in Phases 1 — 5. The dewatering trench around the perimeter of the phase being mined will be placed at the toe of the 3H:1V or 2H:1V mining slope. As the phase is mined deeper the dewatering trench will be lowered and moved laterally along the 3H:1V mining slope toward the center of that phase. Once the interior area becomes small enough where the 3H:1V mining slopes from three to four sides are encroaching upon the portable plant and haul roads another phase will be opened to continue mining. The slurry wall is anticipated to be installed around the perimeter of Phase 1 and prior to starting mining in Phase 2 and it is expected minimal dewatering will be required in id I J&T Consulting, Inc. J-2 Contracting Company DPG Mining Site DRMS 112 Permit Application the subsequent phases due to the slurry wall cutting off groundwater infiltration into the pit. J-2 Contracting Company will have an approved substitute water supply plan and well permit prior to exposing groundwater. The substitute supply plan will be updated annually to account for water that is consumed due to exposing groundwater by the mining operation. Explosives Explosives will not be used during mining. JET Consulting, Inc. J-2 Contracting Company DPG Mining Site DRMS 112 Permit Application EXHIBIT E Reclamation Plan Lined water storage reservoirs will be the final reclaimed use for the DPG Mining site. Portions of mining areas will be reclaimed as "native" areas, which will be re -seeded with native vegetation. The majority of the mining areas will be reclaimed as water storage reservoirs. The remaining area within the proposed permit boundary will consist of reservoir shoreline, unimproved access roads around the reservoirs, and reclaimed or otherwise undisturbed land. Final Land Use Reservoir Water Surface Reclamation Plan Area (acres) 176.80 Access Roads 21.56 Reclaimed Vegetated Land and Undisturbed Land 29.66 TOTAL 228.02 Water Storage Reservoir In general, the mining limits will be mined down to the shale/claystone/sandstone bedrock. The relatively impermeable bedrock will make the bottom of the reservoir. The reservoir will be separated from the surrounding alluvial aquifer by the slurry wall liner system as detailed in the cross-section shown on the Reclamation Plan Map. The slurry wall liner will be keyed into the bedrock material and extend upward through the entire height of the alluvium. Design specifications and quality control procedures used during the construction of the slurry wall liner will ensure that the reservoir meets the State Engineer's Office (SEO) performance standards for permeability. The slurry wall is anticipated to be installed around the perimeter of Phase 1 and 2 after a depth of 30 feet is reached in Phase 1 and prior to starting mining in Phase 2 and it is expected minimal dewatering will be required in the subsequent phases due to the slurry wall cutting off groundwater infiltration into the pit. All reservoir slopes will be reclaimed to at least 3H:1V final grade Since reclamation will be concurrent with mining, most soil, overburden, and bedrock material excavated during mining will be used almost immediately. Scrapers and dozers and compactors will be used to shape the reclaimed slope material along the reservoir perimeters to achieve the final grade. Upon placing the backfill material, 95 percent compaction will be achieved to ensure adequate integrity of backfilled areas for haul/access roads and recharge pond areas that are not within the future water storage/reservoir footprint. Final reclamation by capping with topsoil and re -vegetating above the expected reservoir water level will follow grading operations as well as backfilled areas that will not be haul/access roads to minimize the amount of disturbance at any one time. During reclamation activities, inlet and outlet facilities for the reservoir will be designed and installed once the operational criteria of the proposed reservoir have been identified by an end user. JaT Consulting, Inc. J-2 Contracting Company DPG Mining Site DRMS 112 Permit Application Reclamation Measures/Materials Handling Backfilling will be done to provide stabilized shorelines around the reservoir and to minimize erosion. The backfill material will consist of gravel, overburden, and topsoil. There will not be known toxic or hazardous materials in the backfill material. Additionally, it is not likely that acid forming or toxic materials will be encountered during mining. The mining will not leave high walls on the property. In addition, there will be no auger holes, excavations, or shafts left on the property. Overburden that is not used for production of road base and topsoil that is removed during the mining will be used to reclaim the mining slopes and areas that are disturbed during the mining such as haul/access roads and recharge pond areas. Overburden will be placed in the areas such as haul/roads and the recharge pond areas to bring the grade to the final reclaimed elevation. Topsoil will then be placed to finalize the grading such that seeding can occur. The topsoil will be placed at all disturbed areas and on the mining slope to an elevation matching the expected reservoir water level. Topsoilinq Approximately the top twelve inches of soil on the property is classified as topsoil. This layer includes the root zone of grasses and crops, which will be stripped and stockpiled separately. By using concurrent reclamation techniques, the topsoil is not expected to remain in stockpiles for more than one to five years. If the stockpile remains more than one growing season, it will be seeded with a fast-growing vegetative cover to prevent erosion. All topsoil will be retained on - site to reclaim the reservoir shoreline, and other areas disturbed by mining activities. Where required, topsoil will be replaced to a depth of twelve inches. Revegetation As mining operations are completed, areas for reclamation will be graded and shaped for revegetation. Runoff or excess water from adjacent areas will not be allowed to flow over slopes being graded and seeded. If needed, berms or channels will be constructed to divert excess water and convey it in a safe and non -erosive manner. For disturbed areas, the reclamation plan includes re -vegetating with appropriate seed mixes to minimize erosion and re-establish natural terrain. The seed mixture below was selected to be long lasting and regenerating, as recommended by the Greeley Natural Resource Conservation Service Office (see attached recommendation). The ground will be fine graded prior to seeding and mulch will be applied according to recommendations from the NRCS. Reservoir side slopes below the anticipated reservoir water level will not be seeded. The proposed seed mix is shown in the following table. J&T Consulting, Inc.

If seed is to be broadcast, the application rate will be doubled. The seed mix for final reclamation as described above does not require fertilizer as recommended by the local NRCS office in Greeley, Colorado. The seeded areas will be covered with dead crop litter from sorghum or milo crop forage, or with straw mulch at a rate of 4,000 pounds per acre. If a significant invasion of noxious weeds occurs after seeding, the weeds will be mowed before they can go to seed. The areas will be mowed periodically for additional control as needed. Mechanical control will be used as a first priority. Chemical methods will only be used if no other alternative produces acceptable results. For temporary stockpiles, the reclamation plan includes re -vegetating with appropriate seed mixes to minimize erosion and establish more rapidly to stabilize the stockpiles.

Water — General Requirement To minimize the effect on the prevailing hydrologic balance, J-2 Contracting Company will: a. Comply with all applicable Colorado water laws. b. Comply with all applicable Federal and State water quality laws and regulations. c. Comply with all Federal and State requirements for dredge and fill. d. Re -grade and backfill all sediment and siltation structures after mining is completed. JaT Consulting, Inc. J-2 Contracting Company DPG Mining Site DRMS 112 Permit Application e. Monitor groundwater levels adjacent to the site and mitigate any damage to adjacent wells that dewatering activities may have. (See Exhibit G) Groundwater — Specific Requirements The operation will not affect groundwater quality on or off the site. The operation will comply with State groundwater quality standards. The mining and reclamation may affect the groundwater table surrounding the mine site. The proposed mitigation efforts to minimize these impacts are recharge ponds or ditches in necessary areas to maintain groundwater levels during the mining, and a perimeter drain if needed to convey groundwater around the lined reservoir after the pit side liner is installed. J-2 Contracting Company proposes that they monitor groundwater levels through both interior (within phases of the mining) and exterior (outside the slurry wall lining) monitoring wells that they have installed, or have access to before, during, and after the mining and reclamation is complete so that impacts to the groundwater table, from this mining operation, can be identified and addressed. It is the intent of J-2 Contracting Company to operate responsibly and to mitigate any damage to wells that is directly attributable to the mining and reclamation of this site. Reclamation — Approximate Time Table The maximum proposed rate of production for the mine is 750,000 tons per year. The total time frame to mine all phases is approximately 30 years. The following table shows the approximate time frame to finish each phase of mining: Mine Phase and Acreage Time Frame to Complete and Reclaim Phase Phase 1 — 24.57 acres 4 years Phase 2 — 20.08 acres 3 years 6 months Phase 3 — 56.19 acres 10 years Phase 4 — 44.10 acres 8 years 5 months Phase 5 — 45.43 acres 7 years and 4 months The assumed annual production rate is 750,000 tons for processed material leaving the mine each year. The size and area of reclamation varies for each phase but generally consists of the outside mining slope being reclaimed at a 3H:1V and 3H:1V slope with the addition of overburden, topsoil, and revegetation. For more information on sequencing and size of the reclamation activities refer to Exhibit L financial warranty calculations. !d' J&T Consulting, Inc.

JCV ae n.mml u Sheet: OR 4 EXHIBIT G Water Information Introduction The DPG Mining site is located in the north 1/2 of section 12, and the southwest 1/4 of northeast corner of section 11, township 5 north, range 65 west of the 6th p.m., and the south 1/2 section of section 1, township 5 north, range 65 west of the 6th p.m., Weld County, Colorado. The proposed mining site is located approximately 2 miles north and 2 miles west of the Town of Kersey, and approximately 2 miles north of State Highway 34. The South Platte River is approximately 600 feet south of the site on the west side of the permit boundary and 200 feet south and east of the site on the east side of the permit boundary. The Cache La Poudre River is adjacent to the north side of the permit boundary. The Weld County Parkway is immediately adjacent to the west side of the permit boundary. The operation will consist of sand and gravel production and will impact the South Platte River and the Cache La Poudre River in the form of depletions due to evaporation and operational losses associated with mining. Mining of the DPG Mining site will last for approximately 30 years. Once reclamation is complete reservoirs will be created with a total surface area of Reservoir 1 being 44.17 acres, Reservoir 2 51.40 acres, Reservoir 3 41.60 acres, and Reservoir 4 42.63 acres. The depth to groundwater ranges from 3 to 10 feet within the permit boundary (measured in MW -1 through MW -9, See the attached piezometer measurements table). The site will be mined down to a depth of 67 to 102 feet thus exposing groundwater to the atmosphere. This exposed groundwater, along with the operational losses associated with the extraction of sand and gravel deposits, will impact the South Platte and Cache La Poudre alluvial aquifer. These impacts will cause river depletions that must be augmented. Groundwater will be exposed during the mining once the mining depths reach an elevation of approximately 4596. To enable dry mining at the DPG Mining site, there will be dewatering trenches around the various phases of the site. These dewatering trenches will change in length throughout mining. The maximum length will occur when one phase is completely mined, but before the reclamation has begun on any given phase. The maximum size of dewatering trench will be 2,300 feet long and 5 feet wide, or 0.26 acres of exposed surface area. This water will be collected in a series of settling ponds totaling 8.5 acres. After sediment has settled from the water it will be pumped into dewatering ditch, which traverses the site, and is discharged into the Cache La Poudre River. As mining progresses, the dewatering trenches and discharge settling pond will shift as various cells are reclaimed. The gravel pit will have a slurry wall liner being constructed as mining commences or prior to mining commencing in Phase 1. Water Requirements Water use at the DPG Mining site will include evaporation from exposed groundwater, dust control of haul roads and stockpiles, and water retained in material removed from the site. J&T Consulting, Inc. Journey Ventures, LLC Journey Ventures Pit DRMS 112 Permit Application Evaporative Loss Evaporative losses are dependent on the exposed water surface area, which may shift throughout the mining operation, but will not exceed the maximum. Exposed surface area at the DPG Mining site will include groundwater exposed in the dewatering trenches and discharge settling pond. The maximum exposed surface area at the site during mining is estimated at 0.38 acres. J-2 Contracting Company plans to keep the site dewatered throughout the life of the mine. Evaporation data was taken from NOAA Technical Report NWS 33, Evaporation Atlas for the 48 Contiguous United States. The annual gross evaporation was determined to be 45 inches for this location. Monthly evaporation percentages are established by guidelines set by the State Engineer's Office. To determine precipitation, data from the National Weather Service for Greeley, CO (053553) (1967-2019) was used. The long-term average precipitation at the DPG Mining site is estimated at 14.20 inches. Effective precipitation is calculated as 70% of the total precipitation. The net evaporation is the difference between gross annual evaporation and effective precipitation. The resulting net evaporation is 2.92 feet. The maximum evaporative loss from the 8.76 acres is 25.58 ac -ft. Operational Loss The average annual production from the DPG Mining site is estimated at 750,000 tons. Using 4% moisture content, the total associated consumptive use for water retained in the material mined is 22.07 ac -ft. Dust control use is 10,000 gal/day, 6 days/week, 4 weeks/month for 10 months of the year. This equates to 7.4 ac -ft. Maximum annual operational loss is estimated to be 29.47 ac -ft for Phase 1. Consumptive Use The maximum annual consumptive use at this site during the mining operation is estimated to be 55.05 ac -ft for Phase 1. Replacement Water The replacement of consumptive uses at the site is will be accounted for in a substitute water supply plan (SWSP) approved by the State Engineer. The SWSP will be obtained prior to any mining activities occurring that expose groundwater. Surrounding Water Rights The attached Figure G-1 shows the permitted wells within 600 feet of the mining limits. The well information and locations were obtained from the Division of Water Resources online mapping well permit locator. This well and water rights information was cross checked with the State's CDSS. Between the sources, all permitted and decreed wells are included. Table G-1 below is a corresponding list of wells as numbered in Figure G-1. J&T Consulting, Inc. Journey Ventures, LLC Journey Ventures Pit DRMS 112 Permit Application Table G-1 - Permitted and Decreed Wells Within 600 Feet of Mining Limits Map Permit Structure Zip ID No ID Well Name Owner Address City State Code 1 102669-A W C Mathews 3791 E 18th Street Greeley CO 80631 2 118187-A Weld County P.O. Box 758 Greeley CO 80631 3 76222-F Weld County P.O. Box 758 Greeley CO 80631 At the time of SWSP application/approval, a new gravel pit well permit will be applied for/obtained to include the evaporative and operational losses from the property. If the proposed use of groundwater at the DPG Mining site results in material injury to surrounding wells, J-2 Contracting Company will ensure that all necessary measures are taken to address the issues. Water Quality An NPDES permit will be obtained from the Water Quality Control Division at the Colorado Department of Public Health & Environment for the DPG Mining site prior to discharging any groundwater that is dewatered from the site. This permit will be kept current and amended as necessary to ensure that any water discharged from the site will meet the permitted water quality standards. Impacts to Groundwater/Hydrologic Balance J-2 Contracting Company will monitor the groundwater levels surrounding the site and provide groundwater recharge if necessary via perimeter ditches/ponds. J-2 Contracting Company will construct these ditches/ponds in the locations where direct discharge to an existing adjacent irrigation lateral is not available to ensure that stabilized groundwater levels are maintained. They will discharge dewatering flows into existing adjacent irrigation laterals where possible to limit the disturbance to the surrounding land. Slurry wall liners are proposed around the individual phases and will likely be installed either shortly after mining has begun or prior to mining starting. The only phase that mining may start prior to the slurry wall installation being completed is Phase 1. To summarize the mitigation process, as each phase of mining/dewatering occurs it will draw down the surrounding groundwater level to some extent. J-2 Contracting Company will monitor the groundwater levels adjacent to mine as each phase progresses. If groundwater levels drop to a level that prevents an adjacent well from performing acceptably, according to that well's owner, J-2 Contracting Company will either implement a groundwater recharge ditch/pond near the well in order to raise the groundwater level in the vicinity of the well and hence return it's operation to acceptable standards, or will negotiate an agreement with that well owner to replace the well or provide replacement water via other means until the mining and reclamation activities are concluded. Groundwater wells that are not owned by J-2 Contracting Company (Figure G-1) are potentially located within 600 feet of the mining limits. The exact physical location of these wells will be determined during the SWSP and well permit application processes. If wells are found to be within 600 feet of the mining limits, J-2 Contracting Company will either obtain a well waiver from the owner of the well, or provide an agreement with the well owner that J-2 Contracting !di J&T Consulting, Inc. Journey Ventures, LLC Journey Ventures Pit DRMS 112 Permit Application Company will mitigate and material damage to the well that is directly attributable to the mining and reclamation of the site. All other wells within 600 feet of the mining limits are either owned by J-2 Contracting Company, or are monitoring wells therefore groundwater impacts to these wells do not need to be addressed. See the attached Piezometer Location Map, and Piezometer Data Summary, which show the locations of monitoring wells around the perimeter of the site that J-2 Contracting Company has either installed or has access to, and the groundwater level data that has been collected for each well.

The Screening Report for Federal and State Listed Threatened and Endangered Species from ERC is attached which describes the wildlife habitat present on the site and the common species that may be found in the habitat area. ERC conducted this screening for federal and state threatened, endangered and species of concern for the approximately 265 -acre survey area. The following provides key items identified as part of the report: 1. Four primary vegetation communities exist within the survey area and are comprised of Cultivated Cropland, Upland Grassland Ruderal Herbaceous vegetation, Western Cattail Marsh, and Western Great Plains Riparian Woodland, Shrubland and Herbaceous vegetation (Corner et al. 2003). 2. Generally, there are features on the survey area and the surrounding area that provide general habitat for local songbirds, raptors, waterfowl, amphibians, reptiles, aquatic invertebrate and small to midsize mammals. However, the majority of the habitat on survey area (75%) is classified as Cultivated Cropland and Upland Grassland Ruderal Herbaceous vegetation which is somewhat degraded from a wildlife perspective by historic and current land use practices. Within the survey area, the Western Great Plains Riparian Woodland, Shrubland, and Herbaceous and Western Cattail Marsh vegetation communities occupy a smaller percentage of the survey area (24%) but provides a variety of important wildlife values. 3. Based upon literature review and field evaluation of the Survey area, ERC has determined that some migratory birds likely utilize the Survey area. These birds are protected under the MBTA, and killing or possession of these birds is prohibited. Generally, the active nesting season for most migratory birds in this region of Colorado occurs between April 1 and August 31. Any future land use changes that may occur on Survey area that remove vegetation during the active nesting season should first ensure that active nests are not disturbed. 4. Raptor nest sites are further protected by the CPW. The CPW has established recommended buffer zones and seasonal activity restrictions for a variety of Colorado raptors. One active red-tailed hawk nest was observed during the field investigation and no CPW mapped buffer zones are located within the survey area. In accordance with CPW guidelines no new disturbance should occur within 1/3 -mile of the active red-tailed hawk nest between February 15 and June 15 or until the young have fledged. Once the nest becomes inactive surface occupancy may resume within the 1/3 -mile buffer and vegetation occupied by the inactive nest may be removed. According to the USFWS Region 6 Migratory Bird Conservation Actions for Projects to Reduce the Risk of Take during the Nesting Season, an active nest survey should be performed "no more than 7- 10 days prior to when work actually begins on the project site" to determine the presence and activity status of nests protected by the MBTA. If work for the project must begin prior to the nest becoming inactive within the 1/3 -mile buffer, further agency coordination would be required. 5. Federally listed threatened and endangered species and/or habitat protected under the ESA were evaluated for the survey area. The survey area is within the occurrence range of Preble's meadow jumping mouse (Zapus hudsonius preblei) (PMJM). The PMJM is J&T Consulting, Inc. Journey Ventures, LLC Journey Ventures Pit DRMS 112 Permit Application listed as federally threatened under the ESA. The well -developed Western Great Plains Riparian Woodland, Shrubland and Herbaceous habitat along the Cache la Poudre River or South Platte River, within the northern and eastern portion of the survey area are considered potentially suitable habitat for this species. No PMJM individuals were observed on or surrounding the survey area. The majority of the survey area (south, east, and west) is comprised of cultivated cropland (mowed)/ruderal herbaceous vegetation thus does not provide habitat suitable for this species. The sections of suitable habitat are not continuous throughout the survey area with sections of the river banks too incised to support the structural habitat layers associated with PMJM habitat. The project proposes that a 100 to 140 -foot -buffer be maintained between the Cache la Poudre River and the boundary of the impact area which does preserve much of the potential PMJM habitat. No PMJM populations are known to occur within the area. The nearest known population is approximately 10 miles southwest of the survey area along the South Platte River near the town of Milliken, Colorado. Activities associated with the project may result in loss of potential PMJM habitat. The proposed project and any future land use changes may affect potential habitat of this species however is not likely to adversely affect this species. The proposed project and any future land use changes may affect, not likely to adversely affect this species. 6. Any future project which may be water related or determined to be a water depletion to the South Platte River Basin may potentially be considered an adverse effect to water depletion species. The survey area does not contain the specific habitat characteristics necessary to support the species affected by depletions to the South Platte River. The species do not occur within the survey area therefore the proposed project and any future land use change will not directly adversely affect the continued existence or available habitat of the species. It is assumed herein that proper augmentation plans are in place and the project will not result in a water depletion and therefore not be considered an adverse effect to these species. Furthermore, it is assumed that no federal nexus would be required and therefore, South Platte River Basin depletion species are not concerned. Based on these assumptions and our current understanding of the project, no adverse effect is likely to occur to these species. 7. Upon review of species identified as State endangered or threatened, protected by the CPW under Colorado Statute Title 33, no species are potentially present within the survey area. No individuals or habitat for state listed threatened and endangered species would be impacted by any future land use changes.

(ERC) has prepared this report at the request of J-2 Contracting Company. The approximately 265 -acre property referred to as the DPG Site is located in unincorporated Weld County, Colorado (survey area). The survey area is under consideration for potential future land use changes that will consist of a four phased aggregate extraction operation, which will likely alter a majority of the current survey area landscape, therefore this report has been prepared to identify potential federal and state listed threatened and endangered species and/or habitat that could exist on or immediately surrounding the survey area. In addition, this report provides a cursory screening of general wildlife use characteristics and existing vegetation community types. This report has been prepared in accordance with the Migratory Bird Treaty Act (MBTA), Endangered Species Act (ESA) and Colorado Parks and Wildlife (CPW) Colorado Statute Title 33. 2.0 GENERAL SITE DESCRIPTION The survey area is generally located southeast of the intersection of East 8th Avenue and Weld County Parkway in the Weld County, Colorado in the Outlet Cache la Poudre River (HUC 101900071008) and Owl Creek -South Platte River watershed (HUC 101900030607). The survey area is located in Sections 1 and 12, Township 5 North, Range 65 West, in Weld County (latitude 40.420595° north, longitude -104.609899° west). From the intersection of 1-25 and US -34, the survey area can be accessed by heading east for approximately 1 mile on East 56th Avenue, then east on US -34 for approximately 20.3 mile until County Road 47 1/2. Take County Road 47 1/2 north for 1.0 mile and turn northwest onto County Road 49. Continue east on County Road 49 for 1.3 miles and the survey area is accessible by a dirt access road to the east. The survey area is comprised of farm fields, a single-family dwelling, several manmade seasonally irrigated depressions and ditches, dirt access roads, the Cache la Poudre River, and associated wetlands. Refer to Figure 1 and Figure 2 for a location map and US Geological Survey (USGS) topographic map of the survey area. The survey area comprises approximately 265 -acres and has an average elevation of 4,600 feet above mean sea level. The vicinity of the survey area is comprised largely agricultural land with pockets of wooded areas and a single-family dwelling. Land neighboring the survey area includes the South Platte River and Mitani-Tokuyasu State Wildlife Area to the east; Holly Avenue and the South Platte River to the south; the Cache la Poudre to the north; Weld County Road to the west. The USGS topographic map shows a perennial stream identified as Cache le Poudre River and an intermittent stream flowing to and from the Cache la Poudre River in sections of the northern portion of the survey area. Four primary vegetation communities exist within the survey area and are comprised of Cultivated Cropland, Upland Grassland and Ruderal Herbaceous, Western Cattail Marsh, and Western Great Plains Riparian Woodland, Shrubland and Herbaceous vegetation (Comer et al. 2003) (refer to Figure 3). Cultivated Cropland comprise most of the uplands within the central, southern, and western portions of the survey area. All of the agricultural fields had recently been tilled at the time of the field investigation. The northern portion of the survey area abutting the riparian area along the Cache la Poudre River consists of Upland Grassland and Ruderal Herbaceous vegetation and is dominated by western wheatgrass (Pascopyrum smithii), smooth brome (Bromus inermis), cheatgrass (Bromus tectorum), western tansymustard (Descurainia pinnata), and whitetop (Cardaria draba). 3 .� ERC DPG Site Threatened and Endangered Species Screening The northern portion of the survey area abutting the Cache la Poudre River can be described as Western Great Plains Riparian Woodland, Shrubland, and Herbaceous vegetation. Within this habitat type occurs both riparian wetland habitat and mesic upland habitat. Upland forested areas are dominated by crack willow (Salix fragilis) and plains cottonwood (Populus deltoides) overstory trees with a mixed shrub and herbaceous understory. Riparian wetland habitat associated with the Cache la Poudre is comprised mainly of shrub and forested habitat exhibiting species of narrowleaf willow (Salix exigua), and reed canary grass (Phalaris arundinacea). The Western Cattail Marsh vegetation community occurs in the basins located in the north central portion of the survey area. This community is dominated by narrowleaf cattail (Typha angustifolia), saltgrass (Distichlis spicata), common three -square (Schoenoplectus pungens), and narrowleaf dock (Rumex stenophyllus). The basins appear to be manmade and are separated by upland berms. 4 . ERC DPG Site Threatened and Endangered Species Screening FIGURE 1.

Among others, ERC reviewed the available literature sources including; CPW information and the US Fish and Wildlife Service (USFWS) Federal Register. A field inspection was subsequently conducted on May 1, 2019 to identify and document the presence of natural vegetation communities, general wildlife use and potential for threatened and endangered species/habitat. Upon review of all available resources, including literature and field inspections, ERC provides the following determination for the survey area. 4.0 GENERAL WILDLIFE HABITAT (NON -REGULATED) Wildlife utilizes the general landscape in a multitude of ways and uses a variety of habitats as areas of permanent inhabitance, seasonal inhabitance, breeding grounds, migratory routes, for foraging purposes, or as a temporary shelter. Potential wildlife habitat includes lands characterized as Western Cattail Marsh, Western Great Plains Riparian Woodland, Shrubland and Herbaceous, Upland Grassland and Ruderal Herbaceous, and Cultivated Cropland vegetation. Historic and current land use practices have restricted the development of any significant natural vegetation communities within a majority of the survey area, which limits the overall quality of potential wildlife habitat. Non-native species or ruderal native species which permeate the vegetation communities generally do not provide quality habitat for most wildlife. Although somewhat degraded and lacking in native biodiversity, the agricultural and ruderal herbaceous vegetation communities within the survey area do provide a number of wildlife benefits within the larger regional landscape. Such lands often serve as a buffer between natural areas, providing food, cover, nesting and open -space habitat which allow movement and exchange of plant and animal populations. Cultivated Cropland and Upland Grassland Ruderal Herbaceous uplands are not typically considered of high ecological value to wildlife, but these habitat types have beneficial values to certain wildlife species. These areas at a minimum are considered "open space" providing limited foraging and hunting grounds, refuge and nesting. The Cultivated Cropland vegetation community within the survey area occupies a majority of the land cover percentage of the survey area (58%), occurring in the southern, eastern, and western portions of the survey area. The agricultural land which is present across the survey area has largely replaced the native shortgrass prairie habitat which would have been present in this region. This vegetation community had been recently tilled at the time of the field investigation and generally lacked vegetation in the survey area. The Upland Grassland and Ruderal Herbaceous vegetation community occupies approximately 17% of the survey area and occurs south of the Cache la Poudre River riparian corridor. This community is dominated by smooth brome (Bromus inermis), western wheatgrass (Pascopyrum smithii), and a variety of ruderal forbs. The Upland Grassland and Ruderal Herbaceous community appears to be frequently disturbed. Non-native species or ruderal native species which permeate these vegetation communities generally do not provide quality habitat for most wildlife. In general, agriculture practices have altered the structure, function, community composition, and habitat value of land within the survey area. The Western Cattail Western Marsh and Great Plains Riparian Woodland, Shrubland and Herbaceous vegetation communities can be considered somewhat valuable to wildlife by providing shelter, foraging habitat, nesting habitat, and act as a movement corridor for various small to mid -size mammals, amphibians, birds, and reptiles. The Western Great Plains Riparian Woodland, Shrubland and Herbaceous 9 . ERC DPG Site Threatened and Endangered Species Screening vegetation community within the survey area occupies approximately 20% along the Cache la Poudre in the northern portion of the survey area and along the South Platte in the eastern portion of the survey area. This habitat is a forested riparian area exhibiting overstory canopy trees, midstory shrubs and dense herbaceous understory cover. Overstory canopy trees and midstory shrubs, situated near an agricultural landscape, can provide potential roosting and nesting habitat for visiting and residential raptors and smaller migratory birds. The Western Cattail Marsh vegetation community within the survey area occupies a small percentage of the survey area (4%) in the north central portion of the survey area. This habitat is dominated by narrowleaf cattail (Typha angustifolia) and saltgrass (Distichilis spicata). Cattail marsh provides unique valuable habitat qualities for certain species, including nesting materials, foraging opportunities, and a seasonal water source. The remaining 1% of the land cover consists of roads, structures, and surface water. Some local wildlife species that may use this habitat within the Survey area includes Canada geese (Branta canadensis), common mallard (Anas platyrhynchos), red -winged blackbird (Agelaius phoeniceus), mourning dove (Zenaida macroura), killdeer (Charadrius vociferous), western meadowlark (Sturnella neglecta), Great Plains toad (Anaxyrus cognatus), snapping turtle (Chelydra serpentina), garter snake (Thamnophis sp.), and various other species of fish and aquatic invertebrate. • Generally, there are features on the survey area and the surrounding area that provide general habitat for local songbirds, raptors, waterfowl, amphibians, reptiles, aquatic invertebrate and small to mid- size mammals. However, the majority of the habitat on survey area is classified as cultivated cropland and ruderal herbaceous vegetation which is somewhat degraded from a wildlife perspective by historic and current land use practices. Within the survey area, the Western Great Plains Riparian Woodland, Shrubland, and Herbaceous and Western Cattail Marsh communities occupy a smaller percentage of the survey area; however, these communities do provide significantly higher value wildlife habitat, specifically along the Cache La Poudre River. 5.0 MIGRATORY BIRD TREATY ACT Migratory birds are protected under the Migratory Bird Treaty Act (MBTA) (16 U.S.C. 730-712). The MBTA makes it illegal for anyone to take, possess, import, export, transport, sell, purchase barter, or offer for sale, purchase, or barter any migratory bird, or the parts, nests, or eggs of such a bird except under the terms of a valid permit issued pursuant to Federal regulations. In Colorado, all birds except for the European starling (Sturnus vulgaris), house sparrow (Passer domesticus) and rock pigeon (Columba livia) are protected under the MBTA. A total of 523 migratory bird species are known to occur in the Mountain - Prairie Region (USFWS Region 6, Montana, Wyoming, Utah, North Dakota, South Dakota, Nebraska, Kansas and Colorado); 320 of the 523 migratory bird species are known to breed in USFWS Region 6. Migratory birds likely exist within the survey area. The mature overstory cottonwood trees and open shrub midstory within the Western Great Plains Riparian Woodland, Shrubland and Herbaceous vegetation community on the eastern portion of the survey area provide potential habitat for migratory birds. Several migratory birds were also directly observed within the survey area, including mourning dove, black -billed magoie (Pica hudsonia), American white pelican (Pelecanus erythrorhynchos), American robin (Turdus migratorius), western grebe (Aechmorphorus occidentalis), great blue heron (Ardea herodias), mallards, western meadowlark, red -winged blackbird, black -capped chickadee (Poecile atricapillus), northern flicker (Colaptes auratus), Say's phoebe (Sayornis saya), blue jay (Cyanotta cristata), yellow-rumped warbler (Setophaga coronata), and chipping sparrow (Spizella passerina). Such birds are 10 .� ERC DPG Site Threatened and Endangered Species Screening protected under the MBTA, and killing or possession of these birds (or their parts and nests) is prohibited under the MBTA. • Based upon literature review and field inspection of the survey area, ERC has determined that some migratory birds likely utilize the survey area. These birds are protected under the MBTA, and killing or possession of these birds is prohibited. Future land use changes that may occur on survey area which remove vegetation should first ensure that active nests are not disturbed. Generally, the active nesting season for most migratory birds in this region of Colorado occurs between April 1 and August 31. Three active migratory bird nests, two black -billed magpie and one American robin, were observed during the survey area investigation (Figure 3). CPW recommends that active migratory bird nest protected under the MBTA be left undisturbed until the juvenile bird have fledged or until the nest is no longer in use. The MBTA does not restrict disturbances to inactive nests or the surrounding habitat. • In addition, active raptor nest sites are further protected by the MBTA and CPW. The CPW has established recommended buffer zones and seasonal activity restrictions for a variety of Colorado raptors. One active raptor nest was observed just outside of the eastern survey area boundary and three inactive raptor nests were observed in or just outside of the survey area. The active nest was being attended by a red-tailed hawk (Buteo jamaicensis) during the field inspection. A bald eagle (Haliaeetus leucocephalus) was observed flying west in the northwest corner of the survey area, along the Cache la Poudre River riparian corridor. A pair of Swainson's hawks (Buteo swainsoni) were observed foraging in the southeastern portion of the survey area. A Cooper's hawk (Accipiter cooperii) was observed flying through the canopy east of the basins in the north central portion of the survey area. The bald eagle, Swainson's hawks, and Cooper's hawk were not observed in or near any of the raptor nest sites. No CPW mapped buffer zones are located within the survey area (CPW 2019). • In accordance with CPW guidelines no new disturbance should occur within 1/3 -mile of the active red- tailed hawk nest between February 15 and June 15 or until the young have fledged. Once the nest becomes inactive surface occupancy may resume within the 1/3 -mile buffer and vegetation occupied by the inactive nest may be removed. According to the USFWS Region 6 Migratory Bird Conservation Actions for Projects to Reduce the Risk of Take during the Nesting Season, an active nest survey should be performed "no more than 7-10 days prior to when work actually begins on the project site" to determine the presence and activity status of nests protected by the MBTA. If work for the project must begin prior to the nest becoming inactive within the 1/3 -mile buffer, further agency coordination would be required. 6.0 SPECIES PROTECTED UNDER THE ENDANGERED SPECIES ACT OF 1973 The ESA of 1973 was enacted by the United States to conserve endangered and threatened species and the ecosystems that they depend on. Under the ESA, species may be listed as either "endangered" or "threatened"; both designations are protected by law. The ESA is administered by the USFWS. The USFWS has developed project specific species lists, available online by request, identifying threatened, endangered, and proposed species, designated critical habitat, and candidate species protected under the ESA that may occur within the boundary of the proposed project and/or may be affected by the proposed project (USFWS 2019) (Tracking Number: 06E24000-2019-SLI-0754). The species list for the survey area has identified a total of nine threatened or endangered species within the project area. Species Not within Range of the Survey area The following federally listed threatened and endangered species are identified to occur within Weld 11 .� ERC DPG Site Threatened and Endangered Species Screening County. However, these species are not known to exist within the specific vicinity of the survey area and/or have specific habitat requirements (i.e., elevation range) that are not common in the vicinity of the survey area. Common Name Scientific Name Status Mexican spotted owl Strix occidentalis lucida Federally Threatened • The survey area does not contain the specific habitat characteristics necessary to support the species listed above. The species are not likely to occur within the survey area therefore any future land use changes would not likely adversely affect the continued existence or available habitat of the species. Water Depletions Species The USFWS under the ESA has determined that water depletions in the South Platte River Basin are considered an adverse effect to the listed species identified below. The survey area is considered to be located within the South Platte River Basin. Common Name Scientific Name Status Least tern Sternula antillarium Federally Endangered Pallid sturgeon Scaphirhycchus albus Federally Endangered Piping plover Charadrius melodus Federally Threatened Western prairie fringed orchid Platanthera praeclara Federally Threatened Whooping crane Grus Americana Federally Endangered Any water related project conducted in the Platte River Basin that has a federal nexus; such as federal funding or a federal permits (i.e., Clean Water Act (CWA) Section 404 Permit), is subject to ESA Section 7 Consultation with the USFWS. The consultation is a mandate for water depletion projects that may adversely affect threatened and endangered species that rely on the South Platte River. • The survey area does not contain the specific habitat characteristics necessary to support the species listed above. The species do not occur within the survey area therefore the proposed project and any future land use change will not directly adversely affect the continued existence or available habitat of the species. • The proposed project is an aggregate extraction operation (sand and gravel pit). As part of such operations, formalized augmentation plans are in place to ensure no water depletions occur. A hydraulically impermeable slurry wall is proposed to be installed around the perimeter of the mining operation impacts to ensure no depletions occur during project operations. It is assumed herein that proper augmentation plans are in place and the project will not result in a water depletion and therefore not be considered an adverse effect to these species. • Furthermore, it is assumed that no federal funding, federal permits, or federal authorization (federal nexus) would be required and therefore, South Platte River Basin depletion species are not concerned. • Based on these assumptions and our current understanding of the project, no adverse effect is likely to occur to these species. Species Potentially within Range of the Survey area The following federally listed threatened and endangered species are identified to occur or historically occur within Weld County (USFWS 2015). The Survey area is located within the potential known range for these species to occur. Further analysis was conducted to determine if the species or habitat has the 12 .�►► ERC DPG Site Threatened and Endangered Species Screening potential to exist on the Survey area considering survey area -specific conditions and characteristics. A brief explanation is provided as to the species life cycle, habitat requirements and potential occurrence on the Survey area. The Survey area is not within designated critical habitat of any federally listed species. Common Name Scientific Name Status Colorado butterfly plant Gaura neomexicana var. coloradensis Federally Threatened Preble's meadow jumping mouse Zapus hudsonius preblei Federally Threatened Ute Ladies' -tresses orchid Spiranthes diluvialis Federally Threatened COLORADO BUTTERFLY PLANT (GAURA NEOMEXICANA VAR. COLORADENSIS) The Colorado butterfly plant is listed as federally threatened under the ESA. This plant species is a short- lived, perennial herb endemic to moist soils in mesic or wet meadows of floodplain areas in southeastern Wyoming, north central Colorado, and extreme western Nebraska. This early to mid-seral stage species occurs primarily in habitats created and maintained by streams active within their floodplains, with vegetation that is relatively open and not overly dense or overgrown. The conversion of natural wet meadows and natural riparian corridors to agricultural land and urban development is the primary threat to the continued existence of the species (Federal Register 2000). • The riparian and wetland habitats within the survey area do not exhibit typical habitat of the Colorado butterfly plant. The wetlands are mostly overgrown with dense herbaceous vegetation and/or tree/shrub canopy cover. Furthermore, the Colorado butterfly plant is known to occur at elevations of 5,000-6,400 feet which is not within the elevation range of the survey area (survey area is at an average elevation of 4600 feet) (Federal Register 2000). Neither individuals nor potential habitat for the Colorado butterfly plant were observed on or immediately surrounding the survey area. The proposed project and any future land use changes are not likely to adversely affect the continued existence or potential habitat of this species. PREBLE'S MEADOW JUMPING MOUSE (ZAPUS HUDSONIUS PREBLEI) On May 13, 1998 the US Fish and Wildlife Service issued a final rule to list the Preble's meadow jumping mouse (PMJM) as a federally threatened species under the ESA. PMJM range extends from southwestern Wyoming through eastern Colorado generally below 7,600 feet. Armstrong et al. (1997) described typical PMJM habitats as "well -developed plains riparian vegetation with relatively undisturbed grassland and a water source in close proximity." Also noted was a preference for "dense herbaceous vegetation consisting of a variety of grasses, forbs and thick shrubs" (USFWS 1999). This species is known to regularly travel into adjacent uplands to feed and hibernate. The PMJM hibernates in an underground burrow from September to May. PMJM bears two to three litters per year, averaging five young per litter, in a grass - lined nest. In general, PMJM surveys are recommended for areas with suitable habitat in Weld County below 7,600 feet and within 300 feet of vegetated irrigation canals, ditches, and wetlands. Areas that are highly disturbed or modified (including landscaped lots and paved areas) or wetland areas dominated by cattails are excluded from this recommendation. No populations of the PMJM are known to occur within the vicinity of the survey area (UDFCD 2010). Further, the survey area is not designated as Critical Mouse Habitat by the USFWS (CPW 2019). The nearest known critical habitat occurs at Critical Habitat Units 1, 2, 3, and 4 in Larimer County. No Critical Habitat Units occur in Weld County. The USFWS Mouse Block Clearance Map for the Denver Metro Area (USFWS 2010) which identifies areas exempt from further review for PMJM habitat, shows the survey 13 .� ERC DPG Site Threatened and Endangered Species Screening area does not occur within the Block Clearance Zone, indicating a potential presence of the PMJM within the survey area. • No PMJM individuals were observed on or surrounding the survey area. The majority of the survey area (south, east, and west) is comprised of cultivated cropland (mowed)/ruderal herbaceous vegetation thus does not provide habitat suitable for this species. However, the northern and eastern portion of the survey area near the South Platte River and along the Cache la Poudre River, respectively, do comprise sections of well -developed forested, shrub, and herbaceous habitat which is considered potentially suitable habitat for this species. The sections of suitable habitat are not continuous throughout the survey area with portions of the riverbanks too incised to support the structural habitat layers associated with PMJM habitat. The USFWS recommends that projects within 300 feet of 100 -year floodplains associated with rivers, creeks, and their tributaries be assessed as to their potential direct impacts and indirect impacts to PMJM habitat (USFWS 2004). The project proposes that a 100 to 140 -foot -buffer be maintained between the Cache la Poudre River and the boundary of the impact area which does preserve much of the potential PMJM habitat. No PMJM populations are known to occur within the area. The nearest known population is approximately 10 miles southwest of the survey area along the South Platte River near the town of Milliken, Colorado. Activities associated with the project may result in loss of potential PMJM habitat. The proposed project and any future land use changes may affect potential habitat of this species however is not likely to adversely affect this species. UTE LADIES' -TRESSES (SPIRANTHES DILUVIALIS) The Ute ladies' -tresses is listed as federally threatened under the ESA. The Ute ladies' -tresses occurs in seasonally moist soils and wet meadows near springs, lakes, or perennial streams and their associated floodplains below 6,500 feet in elevation in certain areas of Utah, Colorado, Idaho, Wyoming, and Nevada. Typical sites include early successional riparian habitats such as point bars, sand bars, and low lying gravelly, sandy, or cobbly edges. They seem to require "permanent subirrigation", conditions where the water table is close to the surface, but they are not tolerant of permanent standing water (USFWS 1992). Typical habitat is open and sparsely vegetated, populations decline if trees and shrubs invade the habitat. They do not compete well with aggressive species such as reed canary grass or monocultures of cattails. • A majority of the survey area is comprised of upland agricultural land or herbaceous wetland habitat dominated by monocultures of cattails or dense herbaceous vegetation which is not conducive of this species. The riparian area along the Cache la Poudre River do not consist of point bars, sand bars, or low-lying gravelly, sandy, or cobbly edges. The proposed project would not impact the riparian corridor along the Cache la Poudre. No Ute ladies' -tresses or suitable habitat were identified in the survey area. The proposed project and any land use changes are not likely to adversely affect the continued existence or potential habitat of this species. 7.0 STATE THREATENED AND ENDANGERED SPECIES Species identified as state threatened or endangered are protected by the CPW under Colorado Statute Title 33. State regulations prohibit "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 listed as state endangered or threatened. The CPW also has identified State Species of Special Concern, which are species or subspecies of native wildlife that are currently vulnerable in their Colorado range and have the potential to become threatened or endangered (CPW 2010). Species of Special Concern are not protected under State regulations but the 'take' of individuals and disturbance of 14 . ERC their habitat is strongly discouraged. DPG Site Threatened and Endangered Species Screening All state listed species were screened as potential inhabitants of the survey area based on general habitat requirements and CPW Species Profiles (CPW 2015). ERC evaluated the species listed by CPW as threatened or endangered that could potentially exist on the survey area. All animal species listed above as threatened or endangered by the USFWS are also listed by the CPW as threatened or endangered, respectively, therefore were not duplicated below. Species Not within Range of the Survey area The following listed threatened and endangered species are identified to occur within the state (CPW 2019). However, these species are not known to exist within the specific vicinity of the survey area and/or have specific habitat requirements (i.e., elevation range) that are not common in the vicinity of the survey area (CPW 2019 and USFWS 2019).

The species are not likely to occur within the survey area and therefore, the proposed project or any future land use changes would not likely adversely affect the continued existence or available habitat of the species. 15 A ERC DPG Site Threatened and Endangered Species Screening Species Potentially within Range of the Survey area The following state listed threatened and endangered species are identified to occur or historically occur within Weld County. The Survey area is located within the potential known range for these species. Further analysis was conducted to determine if the species or habitat has the potential to exist on the Survey area considering survey area -specific conditions and characteristics. A brief explanation is provided as to the species life cycle, habitat requirements and potential occurrence on the survey area. Common Name Scientific Name Status Black -footed Ferret Mustela nigripes State Endangered Burrowing owl Athene cunicularia State Threatened River otter Lontra canadensis State Threatened BLACK -FOOTED FERRET (MUSTELA NIGRIPES) The black -footed ferret (BFF) (Mustela nigripes) is a medium-sized mustelid (a member of the weasel family). The BFF is the only ferret species native to the Americas. Its historical range spanned much of western North America's intermountain and prairie grasslands, extending from Canada to Mexico. Historically, BFF habitat coincided with habitats of black -tailed prairie dog (C. ludovicianus), Gunnison's prairie dog (C. gunnisoni), and white-tailed prairie dog (C. leucurus). Prairie dogs make up more than 90% of the BFF's diet. BFF's are limited to open habitat, the same habitat used by prairie dogs: grasslands, steppe, and shrub steppe. It depends largely on prairie dogs: ferrets prey on prairie dogs and utilize their burrows for shelter and denning (Hillman and Clark, 1980). It has been estimated that about 40-60 hectares of prairie dog colony are needed to support one ferret (Belant and Biggins 2008). BFF's once numbered in the tens of thousands, but due to a combination of human -induced threats they were believed to be extinct twice in the 20th century. As of 2015, BFFs have been reintroduced in the wild at 24 survey areas across 8 states, Canada, and Mexico. • No BFF individuals were observed on or surrounding the survey area. No black -tailed prairie dog colonies were observed during the field inspection. According to the USFWS and the CPW, the survey area is located within the Block Clearance Area for BFF survey areas in Colorado (USFWS 2009). The Block Clearance means that land within in the Block Clearance Area no longer contains any wild free - ranging black -footed ferrets and that activities within these areas that result in the removal of black - tailed prairie dogs and/or their habitat will no longer be required to meet the USFWS survey guidelines for black -footed ferrets, or undergo consultation under Section 7 of the ESA (USFWS 2009). The proposed project and any future land use changes within the survey area should not adversely affect the continued existence or potential habitat of this species. BURROWING OWL (ATHENE CUNICULARIA) The burrowing owl (owl) is listed as a state threatened species in Colorado. The owl is small (length of 24 centimeters), long-legged, boldly spotted, and barred with brown and white. The owl is a breeding species across the plains of eastern Colorado however rarely winters in the state. Nesting habitat is abandoned burrows, especially prairie dog colonies, located in grasslands, mountain parks, well -drained steppes, deserts, prairies and agricultural lands from late March through October. The owl can usually be observed on low perches such as fence posts, dirt mounds or the ground. Clutch size of this owl averages six to seven and incubation lasts up to 30 days. The owlets usually run and forage at 4 weeks and fly at 6 weeks. 16 ERC DPG Site Threatened and Endangered Species Screening Primary threats to existence of this species are habitat loss due to intensive agriculture, habitat degradation and fragmentation due to control of burrowing mammals and predation by cats and dogs. • No owl individuals were observed on or surrounding the survey area. The survey area is located within the overall range of the black -tailed prairie dog; however no active colonies were observed on the Survey area. The survey area is subject to fragmentation and human disturbance limiting the potential use of the survey area by this species. The proposed project and any future land use changes within the survey area should not adversely affect the continued existence or potential habitat of this species. RIVER OTTER (LONTRA CANADENSIS) The river otter is listed as a state threatened species in Colorado. River otters vary in length from 26-42 inches, with males larger than females. Their long tapered tails make up about one-third of their length. River otters historically ranged throughout most of the United States and Canada but were extirpated from much of their range in the west. Reintroductions of otter to Colorado began in 1976, and they are now found in small numbers throughout most of western Colorado with a more scattered distribution in eastern Colorado (CPW 2019). River otters may inhabit nearly every aquatic habitat however, they are most likely to occupy beaver ponds, stream channels, and warm water sloughs exhibiting healthy riparian vegetation, woody debris, and log jams (CPW 2019). • No river otter individuals were observed on or surrounding the survey area. River otter populations are listed as known to occur in Weld County (CPW 2019). However, individuals and populations are still rare occurrences within the front range and eastern plains. Further, preferred habitat is usually associated with beaver activity and structures which do not exist within or near the Survey area. The proposed project and any future land use changes on the survey area are not likely to adversely affect the continued existence or available habitat of the species. 8.0 SUMMARY ERC has conducted this screening for federal and state threatened, endangered and species of concern for the approximately 265 -acre survey area. The following provides key items identified as part of this report: 1. Four primary vegetation communities exist within the survey area and are comprised of Cultivated Cropland, Upland Grassland Ruderal Herbaceous vegetation, Western Cattail Marsh, and Western Great Plains Riparian Woodland, Shrubland and Herbaceous vegetation (Corner et al. 2003). 2. Generally, there are features on the survey area and the surrounding area that provide general habitat for local songbirds, raptors, waterfowl, amphibians, reptiles, aquatic invertebrate and small to mid- size mammals. However, the majority of the habitat on survey area (75%) is classified as Cultivated Cropland and Upland Grassland Ruderal Herbaceous vegetation which is somewhat degraded from a wildlife perspective by historic and current land use practices. Within the survey area, the Western Great Plains Riparian Woodland, Shrubland, and Herbaceous and Western Cattail Marsh vegetation communities occupy a smaller percentage of the survey area (24%) but provides a variety of important wildlife values. 17 .� ERC DPG Site Threatened and Endangered Species Screening 3. Based upon literature review and field evaluation of the Survey area, ERC has determined that some migratory birds likely utilize the Survey area. These birds are protected under the MBTA, and killing or possession of these birds is prohibited. Generally, the active nesting season for most migratory birds in this region of Colorado occurs between April 1 and August 31. Any future land use changes that may occur on Survey area that remove vegetation during the active nesting season should first ensure that active nests are not disturbed. 4. Raptor nest sites are further protected by the CPW. The CPW has established recommended buffer zones and seasonal activity restrictions for a variety of Colorado raptors. One active red-tailed hawk nest was observed during the field investigation and no CPW mapped buffer zones are located within the survey area. In accordance with CPW guidelines no new disturbance should occur within 1/3 -mile of the active red-tailed hawk nest between February 15 and June 15 or until the young have fledged. Once the nest becomes inactive surface occupancy may resume within the 1/3 -mile buffer and vegetation occupied by the inactive nest may be removed. According to the USFWS Region 6 Migratory Bird Conservation Actions for Projects to Reduce the Risk of Take during the Nesting Season, an active nest survey should be performed "no more than 7-10 days prior to when work actually begins on the project site" to determine the presence and activity status of nests protected by the MBTA. If work for the project must begin prior to the nest becoming inactive within the 1/3 -mile buffer, further agency coordination would be required. • Federally listed threatened and endangered species and/or habitat protected under the ESA were evaluated for the survey area. The survey area is within the occurrence range of Preble's meadow jumping mouse (Zapus hudsonius preblei) (PMJM). The PMJM is listed as federally threatened under the ESA. The well -developed Western Great Plains Riparian Woodland, Shrubland and Herbaceous habitat along the Cache la Poudre River or South Platte River, within the northern and eastern portion of the survey area are considered potentially suitable habitat for this species. No PMJM individuals were observed on or surrounding the survey area. The majority of the survey area (south, east, and west) is comprised of cultivated cropland (mowed)/ruderal herbaceous vegetation thus does not provide habitat suitable for this species. The sections of suitable habitat are not continuous throughout the survey area with sections of the river banks too incised to support the structural habitat layers associated with PMJM habitat. The project proposes that a 100 to 140 -foot -buffer be maintained between the Cache la Poudre River and the boundary of the impact area which does preserve much of the potential PMJM habitat. No PMJM populations are known to occur within the area. The nearest known population is approximately 10 miles southwest of the survey area along the South Platte River near the town of Milliken, Colorado. Activities associated with the project may result in loss of potential PMJM habitat. The proposed project and any future land use changes may affect potential habitat of this species however is not likely to adversely affect this species. 5. The proposed project and any future land use changes may affect, not likely to adversely affect this species. 6. Any future project which may be water related or determined to be a water depletion to the South Platte River Basin may potentially be considered an adverse effect to water depletion species. The survey area does not contain the specific habitat characteristics necessary to support the species affected by depletions to the South Platte River. The species do not occur within the survey area 18 . ERC DPG Site Threatened and Endangered Species Screening therefore the proposed project and any future land use change will not directly adversely affect the continued existence or available habitat of the species. It is assumed herein that proper augmentation plans are in place and the project will not result in a water depletion and therefore not be considered an adverse effect to these species. Furthermore, it is assumed that no federal nexus would be required and therefore, South Platte River Basin depletion species are not concerned. Based on these assumptions and our current understanding of the project, no adverse effect is likely to occur to these species. 7. Upon review of species identified as State endangered or threatened, protected by the CPW under Colorado Statute Title 33, no species are potentially present within the survey area. No individuals or habitat for state listed threatened and endangered species would be impacted by any future land use changes. This report has been prepared by: ECOLOGICAL RESOURCE CONSULTANTS, INC.

May 6. 21 EXHIBIT I Soils Information According to the Soil Survey of Weld County, Colorado, Southern Part, (United States Department of Agriculture, Natural Resource Conservation Service, Web Soil Survey 2.0, National Cooperative Soil Survey), there are eight major soil types within the project area: 1. Aquolls and Aquents, gravelly substratum 2. Ustic Torriorthents, moderately steep The location of these soil types relative to the project area is illustrated on the attached Natural Resources Conservation Service map and legend. Detailed descriptions of each NRCS soil type are below. Map Unit: 3— Aquolls and Aquents, gravelly substratum Map Unit: 10 — Ellicott -Ellicott sandy — skeletal complex, 0 to 3 percent slopes, rarely flooded See attached NRCS report for the permit boundary area.

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.

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 8 Custom Soil Resource Report generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. 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. 9 Custom Soil Resource Report Weld County, Colorado, Southern Part 3—Aquolls and Aquents, gravelly substratum Map Unit Setting National map unit symbol: 3627 Elevation: 4,000 to 7,200 feet Mean annual precipitation: 12 to 18 inches Mean annual air temperature: 45 to 55 degrees F Frost -free period: 80 to 155 days Farmland classification: Prime farmland if drained and either protected from flooding or not frequently flooded during the growing season Map Unit Composition Aquolls and similar soils: 55 percent Aquents, gravelly substratum, and similar soils: 30 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the mapunit.

(ERC) for the DPG Site Property (study area). ERC conducted a formal routine onsite delineation of aquatic resources within the approximately 265 -acre study area located in unincorporated Weld County, Colorado on April 17, 18, and 19, 2019. A total of 18.37 acres of aquatic resources were identified and mapped within the study area which include: 8.01 acres characterized as PEM wetland habitat, 1.23 acres characterized as PSS wetland habitat, 1.29 acres characterized as PSS/PEM wetland habitat, 1.53 acres characterized as PEM/PFO wetland habitat, 5.85 acres (6,186 linear feet) characterized as R2UBG riverine habitat, and 0.46 acre (5,759 linear feet) characterized as R4UBK riverine habitat. All aquatic resources and water features within the study area have been identified herein. The aquatic resource areas were delineated and mapped as A, B, C, D, E, F, G, H, I, and J. Aquatic Resources G, H, I, and J appear to contain a direct surface connection to downstream Waters of the US. Aquatic Resource H includes the stream channel and fringe wetlands associated with the Cache la Poudre River, which flows east into the South Platte River, a traditional navigable water (TNWs), approximately 0.8 mile east of the study area. Aquatic Resource G appears to have a direct surface connection to the Cache la Poudre River outside of the study area to the west approximately 575 feet from the project boundary. Aquatic Resource I appears to have a direct surface connection to the South Platte River outside of the study area to the east approximately 325 feet from the project boundary. Aquatic Resource J appears to be an irrigation ditch with a direct surface connection to the South Platte River outside of the study area to the east approximately 120 feet for the project boundary. Aquatic Resources A, B, C, D, E, and F do not appear to contain a direct surface connection to other downstream wetlands or waters of the US and are surrounded by uplands. Aquatic Resources A and B are manmade remnant reclaimed shallow aggregate pits.

USGS TOPOGRAPHIC MAP DPG SITE PROJECT WELD COUNTY, CO LO RA D O Survey Area Approxmiate Location 1,750 IFnet 3 ERC DPG Site Aquatic Resource Delineation Report 3.0 METHODLOGY The aquatic resource delineation was conducted following the methodology enumerated in the 1987 Corps of Engineers Wetlands Delineation Manual and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Great Plains Region (Version 2.0) (herein referred to as "Supplement") (Environmental Laboratory 1987, USACE 2010). During the field inspection, dominant vegetation was recorded, representative hydrologic indicators were noted and soil samples were examined for hydric indicators. Delineation field work for the study area was completed on April 17, 18, and 19, 2017. The weather during the delineation was sunny and dry with gusty winds at approximately 65 degrees Fahrenheit. The conditions observed within the study area were typical for the region and sufficient indicators of vegetation, soils and hydrology were observed to make a wetland determination. The following definitions provided the basis of this aquatic resource delineation. The USACE and the Environmental Protection Agency (USEPA) jointly define wetlands as: "those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions" [40 CFR 230.3(t)]. Three general environmental parameters define a wetland. These parameters must include the presence of hydrophytic vegetation, hydric soils, and wetland hydrology. Except under certain situations, evidence of a minimum of one positive wetland indicator from each of the above parameters must be identified in order to make a positive wetland determination. In addition, waters of the US are also defined as areas that "include essentially all surface waters such as rivers, streams and their tributaries, all wetlands adjacent to these waters, and all ponds, lakes and reservoirs": The boundaries of some waters of the US (i.e., such as streams or lakes) are further defined by the ordinary high water mark (OHWM). The OHWM is characterized as "the line on the shores established by the fluctuations of water and indicated by physical characteristics such as: a clear natural line impressed on the bank, shelving, changes in the character of the soil, wetland vegetation, the presence of litter and debris, and other appropriate means that consider the characteristics of the surrounding areas" (USACE 2005). Areas that do not meet any one of the wetland parameters (hydrophytic vegetation, hydric soils and/or wetland hydrology) or non -vegetated stream channel/open water (OHWM) were classified as a non - wetland (upland) and mapped as such. Any area determined to be potential waters of the US was delineated in the field with pink pin flags and ribbon identified with 'WETLAND BOUNDARY' printed on it and sequentially labeled alpha -numerically (i.e. Al, A2...). Each wetland determination point was recorded using a hand-held Trimble GeoXH global positioning system (GPS) receiver. The resulting GPS data were post processed using GPS Pathfinder Office 5.85 software. Post processing differential correction provided an average horizontal mapping accuracy of +/- 2 feet. Post -processed GPS data were imported into ArcMap Geographic Information Systems (GIS) (Version 10.5) for spatial analysis and mapping. All aquatic resources delineated within the study area are 4 ERC DPG Site Aquatic Resource Delineation Report depicted on the Aquatic Resource Delineation Maps dated May 8, 2019 are provided as Appendix A. Wetland Determination data sheets are provided in Appendix B. 4.0 EXISTING CONDITIONS 4.1 LANDSCAPE SETTING The study area is situated within the Great Plains ecoregion (Bailey 1976) at an approximate elevation of 4,600 feet above mean sea level (AMSL). The vicinity of the study area is comprised largely agricultural land with pockets of wooded areas and a single-family dwelling. Land neighboring the study area includes the South Platte River and Mitani-Tokuyasu State Wildlife Area to the east; Holly Avenue and the South Platte River to the south; the Cache la Poudre to the north; Weld County Parkway to the west. The landscape within the study area is characterized by the Upland Grassland and Ruderal Herbaceous, Cultivated Cropland, Western Cattail Marsh, and Western Great Plains Riparian Woodland and Shrubland vegetation (Comer et al. 2003). The Western Great Plains Riparian Woodland and Shrubland vegetation encompasses the aquatic resource habitats near the South Platte and Cache la Poudre Rivers (Aquatic Resource H), and in the central portion of the study area north of the single-family dwelling. The aquatic resource habitats exhibiting Western Cattail Marsh vegetation occur in topographic depressions (Aquatic Resource A and B) within the north central portion of the study area. The majority of the study area has been in recent agricultural production. The Cultivated Cropland vegetation community occurs throughout the eastern, western, and southern portions of the study area. The Upland Grassland and Ruderal Herbaceous vegetation community was observed abutting the Cache la Poudre River riparian area to the south. The USGS topographic map shows a perennial stream identified as Cache le Poudre River (Aquatic Resource H) in sections of the northern portion of the study area. This feature was investigated in the field and the stream channel and associated wetland were delineated. Additionally, an unnamed intermittent stream depicted flowing generally east in an oxbow pattern to and from the Cache la Poudre River in the north central portion of the study area. The unnamed intermittent oxbow stream was evaluated in the field and found to be mostly dominated by upland vegetation with pockets of wetlands (Aquatic Resources C, D, E, and F). 4.2 AQUATIC RESOURCES A total of 18.37 acres of aquatic resources were delineated by ERC within the study area. Delineated aquatic resources were classified according to physical and biological characteristics using the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin Classification System) (Cowardin et al. 1979). Within the study area, wetland habitat types were classified based on field evaluation and are summarized below in Table 1. Summary of Aquatic Resources Delineated within the Study area. A description of the aquatic resource habitat types is provided as follows. Refer to Table 2 for a list of vegetation identified within the study area (Lichvar et al. 2016).

AQUATIC RESOURCES A AND B (4.28 ACRES AND 2.20 ACRES) Aquatic Resources A and B are situated in the bottom of two manmade remnant reclaimed shallow aggregate pits. PEM wetland habitat has developed in the topographic lowest points within the two pits. Aquatic Resources A and B are manmade excavated wholly in uplands, recontoured, revegetated and routinely mowed. Two culverts appear to direct irrigation water into the pits (one culvert from the south in Aquatic Resource D) and one from an upland basin from the north. These culverts appear to direct seasonal irrigation water into the pits, however there is no outflow. Aquatic Resources A and B are surrounded entirely by uplands/uplands berms with no direct surface connection to other Waters of the US. Overall, the vegetation communities of Aquatic Resources A and B are dominated by species such as saltgrass (Distichlis spicata), narrowleaf cattails (Typha angustifolia), reed canarygrass (Phalaris arundinacea), common three -square (Schoenoplectus pungens), and narrowleaf dock (Rumex stenophyllus) areas contain a seasonal flooded water regime. The dominant species within the wetland areas consists of species designated as OBL-FACW. 6 ERC DPG Site Aquatic Resource Delineation Report Soils within Aquatic Resources A and B are gravelly silty clay loam textured meeting the criteria for hydric soil indicator F6 (Redox Dark Surface). At the time of delineation, primary wetland hydrology indicators of C3 (Oxidized Rhizospheres Along Living Roots) were observed within Aquatic Resources A and B, in addition to secondary hydrology indicators of B10 (Drainage Patterns), D2 (Geomorphic position), and D5 (FAC-neutral test). The wetland habitat within Aquatic Resources A and B meets the criteria for wetland based on the presence of hydrophytic vegetation, hydric soils, and wetland hydrology. Aquatic Resources A and B comprise a total of 6.48 acres within the study area. Refer to Photos 1-2 below for characteristics of Aquatic Resources A and B. Photo 1.

The wetland boundary is depicted by the blue line. AQUATIC RESOURCES C, D, E, AND F (0.09 ACRES, 0.68 ACRES, 0.43 ACRES, AND 0.03 ACRES) Aquatic Resources C, D, E, and F comprise PSS wetland habitats situated in four separate topographic depressions separated by manmade upland berms. Each area appears to have been previously excavated wholly in uplands with no direct surface connection to other Wates of the US. Aquatic Resource D appears to contain a direct culvert connection to Aquatic Resource A towards the north. Two additional culverts were observed on the east side of Aquatic Resource D, however only direct flows to uplands. Aquatic Resources C, D, E, and F do not appear to contain direct surface connections with any downstream Waters of the U.S. Portions of Aquatic Resource C were recently mowed prior to the delineation. The vegetation communities of Aquatic Resources C, D, E and F are dominated by narrowleaf cattail, reed canarygrass, narrowleaf willow (Salix exigua), and narrowleaf dock. Crack willow (Salixfragilis) and plains cottonwood (Populus deltoides ssp. monilifera) trees were observed in and along the wetland habitat. These areas contain a seasonally flooded water regime. The dominant species within these wetland areas consists of species designated as FAC-OBL. Soils within Aquatic Resources C, D, E, and F are clay to clay loam textured meeting the criteria for hydric soil indicators F6 (Redox Dark Surface). At the time of the delineation, primary hydrology indictors such as C3 (Oxidized Rhizospheres Along Living Roots) were observed within these Aquatic Resources, in addition to secondary hydrology indicators of D2 (Geomorphic Position), D3 (Drainage Patterns), and D5 (FAC-neutral test). The wetland habitat within Aquatic Resources C, D, E, and F meets the criteria for 7 A ERC DPG Site Aquatic Resource Delineation Report wetland based on the presence of hydrophytic vegetation, hydric soils, and wetland hydrology.

AQUATIC RESOURCE J (1.13 ACRE and 5,759 LINEAR FEET) Aquatic Resource J comprises PEM wetland habitat abutting an unvegetated irrigation ditch (R2UBK) situated along the southern boundary of the study area. Six irrigation ditch gates occur along Aquatic Resource J within the study area. At the time of the delineation, water was flowing east in the 6 to 10 - foot -wide ditch. Wetland vegetation was observed in 2 to 10 -foot -wide patches of fringe abutting the ditch bottom. The delineated boundary is largely based on indicators of hydrology and OHWM as there is a clear line on the banks indicating recent water levels. Where wetland fringes were observed, the vegetation community of Aquatic Resource J is dominated by reed canarygrass. This area contains an artificially flooded water regime. The dominant species within this wetland are consists of species designated as FACW. Aquatic Resource J appears to contain a direct surface connection to the South Platte River offsite of the study area to the east. Aquatic Resource J comprises approximately 1.13 acre (5,759 linear feet) within the study area.

Upland habitat within the study area consists primarily of agricultural land. According to the USGS GAP Analysis land cover data set of two primary upland vegetation communities within the study area and include: Cultivated Cropland, Upland Grassland and Ruderal Herbaceous vegetation (Corner et al. 2003). A summary description of the Upland Grassland and Ruderal Herbaceous vegetation community which is predominant within the study area is provided as follows. The Upland Grassland and Ruderal Herbaceous vegetation community encompasses the upland habitat within the study area abutting the Cache la Poudre riparian corridor. The uplands are dominated be smooth brome (Bromus inermis), western wheatgrass (Pascopyrum smithii), and various ruderal forb species. Vegetative cover across these areas generally comprises approximately 70-80% cover. Limited tree and shrub cover are present in this community. The cultivated cropland vegetation community within the the study area comprise cultivated currently exhibit tilled rows with sparse to no vegetation. This community is dominated by cheatgrass (Bromus tectorum) and kochia (Bassia scoparia). Plains cottonwood trees were observed near the single-family home in the south central portion of the study area. Vegetative cover across these areas generally comprises approximately 0-10% cover. The upland habitats across the study area are dominated by FAC-UPL species with dry, light-colored loam, sandy loam, and clay loam soils. In general, the Upland Grassland and Ruderal Herbaceous and Cultivated Cropland vegetation communities across the study area did not meet the criteria for wetland based on lack of at least one required parameter (hydrophytic vegetation, hydric soils, and/or wetland hydrology). Refer to Photos 13-16 below for characteristics of upland habitat identified within the study area. 1 ERC DPG Site Aquatic Resource Delineation Report Photo 13.

US Army Corps of Engineers Great Plains — Version 2.0 EXHIBIT K Climate Climate information was available for the Greeley, CO (053553) weather station from the Western Regional Climate Center. The climate data collected from 1967 through 2019 indicates the average total annual precipitation at the site to be approximately 14.20 inches per year. Monthly average temperature and precipitation data for the 40 -year period of record are provided in the following table: Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Annual Average Max.

J-2 Contracting Company DPG Pit DRMS 112 Permit Application EXHIBIT L Reclamation Cost A phased and cumulative bonding approach is proposed for the DPG Mining site operation. The financial warranty required for each phase is the warranty required to completely reclaim that phase. The financial warranty required for each phase of mining includes a cost component for the slurry wall liner required to close the current mined area should project be stopped and the operator defaulted. Because the slurry wall liner required to close the current mined area for each phase of mining is replaced with a new slurry wall liner required to close the current mined area component as the next phase of mining occurs, the financial warranty required for this component for the previous phase is credited back in each phase's required financial warranty calculation. This accurately calculates the additional financial warranty required for any given phase of mining and for the current limit of disturbance as well as accounting for the financial warranty that has already been posted to ensure that the Division has sufficient cumulative financial warranty to complete the reclamation. Direct costs related to the construction of the reclamation components that have been included in the financial warranty calculations include: Scarifying disturbed ground surfaces, re -applying topsoil over disturbed areas, revegetating disturbed areas, dewatering the full pit, slurry wall liner construction, and contractor mobilization. The slurry wall liner construction costs have been broken down further to include costs for different depths to bedrock as provided from the DRMS on previous 112 applications. Overhead, profit, and project management costs were then calculated and added to the direct construction costs to arrive at the required financial warranty for each phase. As each new phase is started, the financial warranty for that phase will be posted with the Division. When a phase has been reclaimed, inspected, and accepted by the Division, the associated financial warranty for that phase can then be reduced/released to 20% of the financial warranty required for that phase. Please see the attached calculations for details of the costs and quantities used to determine the financial warranty required for each phase of mining. The following table summarizes the financial warranty required for each phase, and the cumulative financial warranty that will be provided during any given phase. J&T Consulting, inc.

J-2 Contracting Company - DPG Pit Slope Stability Analysis Page ii INTRODUCTION J-2 Contracting Company proposes to mine the property located in the South half of the Southwest quarter of Section 1, South half of the Southeast quarter of Section 1, North half of Section 12, and East half of the Southeast quarter of Section 11, Township 5 North, Range 65 West, Sixth P.M. in Weld County, Colorado. The property is bounded by the South Platte River on the south and east, Weld County Parkway on the west, and Cache la Poudre River on the north. The proposed mining operation will extract gravel reserves from locations adjacent to man-made structures. The rules and regulations of the Division of Reclamation, Mining, and Safety (DRMS) require that any mining within a 200 foot setback of a man-made structure show thorough engineering analysis that the proposed mining will not cause damage. The accepted method of demonstrating this is through a slope stability analysis. This report contains an overview of the methodology used in the analysis of the mining slopes and their estimated affects on all man-made structures. Recommendations regarding acceptable setbacks from man-made structures have also been included. OVERVIEW The DRMS mining plan proposes that the property will be mined in 4 pits. The mining will occur at 3H:1V slopes. Concurrent reclamation is planned such that the reclamation embankment will be constructed as the mining progresses. The reservoir will cover an estimated 183 surface acres when full. Actual surface area will depend on the final configuration of the reservoir after reclamation is complete. GEOTECHNICAL DATA Preliminary geotechnical investigations have been performed by Cesare, Inc. J&T Consulting, Inc. (JT) estimated soil strength parameters based on the information from the geotechnical investigation and other stability analyses that have been performed on gravel mining operations along the Front Range. Table 1, on the following page, represents a summary of the soil strength parameters that were used in this stability analysis. V� J&T Consulting, Inc. J-2 Contracting Company - DPG Pit Slope Stability Analysis Page 1 Table 1 - Soil Properties Description Max dry density (pcf) Saturated Density (pcf) Cohesion (psf) Internal Friction Angle Overburden 110 131 150 22 Sand and Gravel 110 125 0 35 Clay 107 130 50 24 Weathered Bedrock 125 141 100 18 Stable Bedrock 125 141 2000 20 Slurry Wall 100 110 0 45 DESIGN ANALYSIS AND CRITERIA The proposed mining slopes were analyzed using Clover Technologies Galena Slope Stability Analysis System, version 7.1. Galena was designed to analyze the slope stability of earth embankments subjected to several critical situations that may occur during the life of the embankment. For this project, eleven cases were identified as critical during the mining operation. Static and pseudo -static conditions were analyzed in each case. Pseudo -static peak acceleration factors (peak horizontal acceleration, or PHA) were taken from USGS information for the western United States. The 2% probability of exceedance in 50 years (the most conservative) was used. A peak acceleration factor of 0.10 x gravity was taken from this data. A conservative earthquake loading coefficient of 0.50 x PHA is often used for slope stability analyses (50% of PHA). We used an even more conservative approach and used 70% of the PHA for this area for our earthquake loading coefficient. Hence, 0.70 x 0.10 = 0.07. All mining side slopes will be 3H:1 V. Case 1 — Wetland West of Reservoir 1. The mining operation is adjacent to a wetland near the west property line of the site. The proposed setback for mining is 50 feet from the east boundary of the wetland. The mining depth was assumed to be 90 feet in this area based on bore log information in the geotechnical report. Case 2 — Cache La Poudre River. The mining operation is adjacent to the Cache la Poudre River on the north side of the mining site. The mining depth was assumed to be 80 feet in this area based on bore log information in the geotechnical report. The proposed mining setback was set 100 feet to the river bank. Case 3 — Cache La Poudre River. The mining operation is adjacent to the Cache la Poudre River on the north side of the mining site. The mining depth was .]&T Consulting, Inc. J-2 Contracting Company - DPG Pit Slope Stability Analysis Page 2 assumed to be 60 feet in this area based on bore log information in the geotechnical report. The proposed mining setback was set 100 feet from the river bank. Case 4 — Gas Line Easement. The mining operation is adjacent to a pipeline easement along the East of the mining site. The mining depth was assumed to be 85 feet in this area based on bore log information in the geotechnical report. The proposed mining setback was set 50 feet from the pipeline easement. Case 5 — Gas Line Easement. The mining operation is adjacent to a pipeline easement along the East side of the mining site. The mining depth was assumed to be 100 feet in this area based on bore log information in the geotechnical report. The proposed mining setback was set 50 feet from the pipeline easement. Case 6 — Weld County Parkway Right -of -Way. The mining operation is adjacent to the Weld County Parkway right-of-way to the west. The mining depth was assumed to be 80 feet in this area based on bore log information in the geotechnical reports. The proposed mining setback was set 50 feet from the right-of-way. Case 7 — Irrigation Ditch & Gas Line Easement. The mining operation is adjacent to an irrigation ditch and two pipeline easements along the East side of the pit. The mining depth was assumed to be 60 feet in this area based on bore log information in the geotechnical reports. The proposed mining setback was set 50 feet from the irrigation ditch. Case 8 — Irrigation Ditch & Gas Line Easement. The mining operation is adjacent to an irrigation ditch and pipeline easement along the South side of the pit. The mining depth was assumed to be 75 feet in this area based on bore log information in the geotechnical reports. The proposed mining setback was set 50 feet from the irrigation ditch. Case 9 — Power Line. The mining operation is adjacent to an overhead electric line along the South side of the pit. The mining depth was assumed to be 100 feet in this area based on bore log information in the geotechnical reports. The proposed mining setback was set 50 feet from the power line. Case 10 — Irrigation Ditch. The mining operation is adjacent to an irrigation ditch along the South side of the pit. The mining depth was assumed to be 100 feet in this area based on bore log information in the geotechnical reports. The proposed mining setback was set 50 feet from the ditch. Case 11 — Gas Line Easement. The mining operation is adjacent to a pipeline easement along the South side of the pit. The mining depth was assumed to be 90 feet in this area based on bore log information in the geotechnical reports. The proposed mining setback was set 50 feet from the pipeline easement. VI J&T Consulting, Inc. J-2 Contracting Company - DPG Pit Slope Stability Analysis Page 3 The cross -sections located in Appendix B show the estimated phreatic surface associated with each case as well as the geometry used in the mining. METHODOLOGY The mining embankment configuration shown in the computer analysis represents the estimated conditions for this site. If mining conditions differ from the estimated conditions, the slope stability will need to be re-evaluated on a case by case basis. The Bishop Method was used in the computer analysis for determining safety factors. The procedure searches for circular shear failures and automatically searches for the lowest safety factor. 20,000 separate failure surfaces were analyzed for each case. The required minimum safety factors are based on the current standards used by the Colorado State Engineer's Office (SEO) in evaluating embankment dams, and industry accepted standards for the evaluation of temporary structures during construction. SLOPE STABILITY RESULTS The SEO requires minimum safety factors of 1.3 for static condition analyses and 1.0 for pseudo -static (earthquake loading) condition analyses for Class I (high hazard) embankment dams. This design criteria was used to establish the desired minimum safety factors for this project and should be considered as highly conservative for evaluating alluvial mining slopes. The calculated factors of safety are within the design criteria specified for this project and can be considered indicators of the mining slope performance under the various conditions.

J-2 Contracting Company - DPG Pit Slope Stability Analysis Page 8 The following recommendations for monitoring of slope stability should be followed: 1. A visual inspection of the excavated slopes should be done on a weekly basis for the duration of mining. This inspection should consist of walking the existing ground and looking for any signs of stress cracks or other potential signs of slope failure. Some minor sloughing of slopes is expected on any mine site. The intent of this inspection is to locate potential major slope failures that could potentially extend back into a structure. 2. A visual inspection should be done after a major precipitation event that has saturated the ground using the same procedures. A major precipitation event would be defined as a storm that produces an intensity level reached once in 50 years on the average. 3. If a visual inspection detects signs of a potential slope failure, qualified personnel should be contacted to evaluate and recommend remediation work to stabilize the area. 4. If no visible signs of slope failure are detected during mining, then the inspection period could be reduced to once per 6 months after mining completion, or after every major precipitation event.

Exploratory borings B-1 through B-23 were drilled from January 22 through 25, 2019, using a CME-75 drill rig with a 6 -inch diameter continuous flight solid stem auger. 2. Groundwater was encountered at depths of 3 to 10 feet below ground surface in borings B-1 through B-23 at the time of drilling. For safety purposes, borings were backfilled immediately after drilling. 3. Contacts between soil units are approximate and may be gradational. Gravel sizes as described in this legend are estimates and are based on input from drillers, and cuttings brought to the surface during drilling. At various locations and depths of drilling, cuttings were not brought to the surface and the material type logged and presented in these logs, is based on driller input and our assumptions based on previous experience. 4. These logs are subject to the limitations and conclusions in this report. Project No. 19.3016. APPENDIX E J&T Consulting, Inc.

Division of Reclamation, Mining, & Safety 1313 Sherman Street, Room 215 Denver, CO 80203 RE: J-2 Contracting Company — DPG Pit Floodplain Study To whom it may concern, We have prepared this letter to address the effects of mining activities at the DPG Pit on the Cache la Poudre River and South Platte River 100 -year floodplain. The floodplain has been modeled to determine the effects resulting from temporary stockpiles located within the pit boundary. The mining area lies within the 100 -year floodplain as shown on the Colorado Hazard Mapping Program (CHAMP) floodplain review web site. The floodplain maps in Appendix A depict the location of the 100 -year floodplain shown on the CHAMP web site, and locations of the HEC- RAS cross -sections used in our modeling for both the Cache la Poudre River and South Platte River. The effect the mining operation has on the 100 -year floodplain is the temporary stockpiling of aggregate products generated by processing the sand and gravel deposit through the processing facility and the stockpiling of overburden and topsoil that is stripped from the site prior to mining. We assumed the largest block -outs in the floodplain by the stockpiles to determine the worst -case effect on the floodplain. The topography shown on the floodplain maps was developed from a photogrammetric drone survey done by Mr. Rob Valentine, with a photo date of January 16, 2019. Ground control points for the survey were provided by American West Land Survey Co. 1 -foot interval topography was developed from the photo. This topography, along with the CHAMP HEC-RAS models were used to model the effects of the stockpiles on the floodplain. The CHAMP HEC-RAS models were obtained from AECOM for the area in the immediate vicinity of the mining activities. The study area for this modelling included the reach from Sections 12+34.80 through 88+03.94 of the Cache la Poudre River HEC-RAS model; 88+03.94 being the upstream study limit, and 12+34.80 being the downstream study limit, and the reach from Sections 13965+52 through 14041+82 of the South Platte River HEC-RAS model; 14041+82 being the upstream study limit, and 13965+52 being the downstream study limit. Two models for each river reach were developed for the site using HEC-RAS 5.0.7 software: 1) A duplicate effective floodplain model was developed showing the limits and elevations of the 100 -year floodplain (base flood) and floodway using the HEC-RAS files obtained from AECOM. The results from this model were compared to the results shown in original AECOM model to ensure that they matched. 641 305 Denver Avenue — Suite D • Fort Lupton CO 80621 • Ph: 303-857-6222 • Fax: 303-857-6224 RE: J-2 Contracting Company — DPG Pit Floodplain Study Page 2 2) A mining conditions floodplain model was developed showing the effect on the 100 -year floodplain from the stockpiles within the mining area relative to the Duplicate Effective model. This model incorporated modified cross -sections from the CHAMP model that included the topography and obstructed flow areas resulting from the construction of temporary stockpiles within the mining area. The duplicate effective and mining conditions HEC-RAS cross -sections and output files are included in Appendix C. The 100 -year Floodplain Elevation Summary in Appendix B shows the results of the duplicate effective and future conditions models for the study area. A maximum rise of 0.15 feet from the duplicate effective 100 -year flood elevations occurs at cross-section 67+57.88 of the Cache la Poudre River model. A maximum rise of 0.17 feet from the duplicate effective 100 -year flood elevations occurs at cross-section 14027+08 of the South Platte River model.
