The proposed mining site is located approximately 1 mile north and 1 mile west of the Town of Kersey, and approximately 1 mile north of State Highway 34. The South Platte River is approximately 2,500 feet north of the site and the North and South Branches of the Plum Ditch are adjacent to the north side of the permit boundary. Weld County Road 51 is immediately adjacent to the east side of the permit boundary. Weld County Road 58 is adjacent a portion of the permit boundary on the south side of the site. Access to the site will be located at the southwest corner of the permit boundary off of Weld County Road 58. 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 84.63 acres with approximately 70.16 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 setback from any existing oil/gas facility will be maintained until that time. See Exhibit C, Mining hid' JxT Consulting. Inc. Journey Ventures, LLC. Journey Ventures Pit DRMS 112 Permit Application • • • 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 Journey Ventures Pit site. The principal intended use for the sand and gravel is for road base and construction aggregates. Subsurface drilling and testing has verified that the Journey Ventures Pit property contains a significant commercial deposit of sand and gravel. The depth of the overburden ranges from 2 to 5 feet. The thickness of the aggregate material ranges from 55 to 80 feet. The overall depth to bedrock ranges from 51 to 107 feet. Mining Methods The deposit will be dry mined and a slurry wall will be constructed around the perimeter of the mining area either prior to Phase 3 or at some point between Phases 3 and 11 of the mining. 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 3-11 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 an irrigation lateral, which traverses the site and eventually discharged into the South Platte 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 outside 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 or bedrock material will be stockpiled long-term prior to use in the reclamation slopes and in production of road base. During mining the mining face will have a 3H:1V slope for the top 13 feet starting at an elevation of 4594 in most cases, and then transition to a 2H:1V slope to bedrock or the bottom of the future reclaimed reservoir. A 3H:1V slope will be used at all locations above the anticipated normal water surface elevation of 4591 once the pit is reclaimed as a water storage reservoir. Ja Consulting. Inc. Journey Ventures, LLD. Journey Ventures Pit DRMS 112 Permit Application • • • The 3H:1V slope will continue to a depth 10 feet below the normal water surface elevation to an elevation of 4581. The processed aggregate material will be temporarily stockpiled near the portable processing plant which lies outside the floodplain. 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 is approximately 113,000 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 Phase 1 — 11. The height of the topsoil stockpile will be approximately 15 feet. Mine Phasing Journey Ventures, LLC anticipates mining and reclaiming the Journey Ventures Pit site in 11 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 25 years. Maximum production is expected to be 250,000 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. Journey Ventures, LLC will mine to an elevation of 4594 in Phase 1 — 2 of the mining plan encompassing a total of 12.61 acres of the mining limits and groundwater will not be exposed. It is expected that 2 phases will be disturbed at any given time, and if more are disturbed Journey Ventures, LLC 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 2H:1V slope. The mining slope will be established for the entire perimeter of the phase in 3 to 6 feet intervals. In Phases 3 — 11 a dewatering trench around the perimeter 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 and then the 2H:1V mining slope toward the center of that phase. Once the interior footprint becomes small enough where the 2H: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. In Phase 11 the mining operation will not mine down to bedrock but rather to an elevation of 4520. The slope stability study indicates that a factor of safety of 1.25 cannot be achieved for the proposed mining slopes at a depth greater than the elevation of 4520. Dewatering Dewatering trenches will be placed along the perimeter of each mining area in Phases 3 — 11. 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 or 2H:1V mining slope toward the center of that ing JaT Consulting. Inc. Journey Ventures, LW.

Once the interior area becomes small enough where the 2H: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 prior to Phase 3 or at some point between Phase 3 and 11 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.

Portions of mining areas in Phases 1, 2, and 11, will be reclaimed as "native" areas, which will be re -seeded with native vegetation. The majority of the mining areas will be reclaimed as a water storage reservoir. The remaining area within the proposed permit boundary will consist of reservoir shoreline, unimproved access roads around the reservoir, and reclaimed or otherwise undisturbed land. Final Land Use Reclamation Plan Area (acres) Alternate Reclamation Plan Area (acres) Reservoir Water Surface 56.65 61.36 County Roads/Access Roads 2.46 1.96 Reclaimed Vegetated Land and Undisturbed Land 25.52 21.31 TOTAL 84.63 84.63 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 liner will be constructed prior to Phase 3 or at some point between Phase 3 and Phase 11. All reservoir slopes will be reclaimed to at least 3H:1V final grade for elevations above 4581 feet and a 2H:1 V final grade for lower slope of the reservoir below an elevation of 4581 feet. The top of the reservoir starts at elevation 4594 where the anticipated normal water surface will be at an elevation of 4591 feet. 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 place 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 insure adequate integrity and permeability of the slope. Final reclamation by capping with topsoil and re -vegetating above the expected reservoir water level will follow backfilling operations closely 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. hi Consulting. Inc. Journey Ventures, LLC. Journey Ventures Pit DRMS 112 Permit Application 20 • • 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 native bedrock, 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 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 the recharge pond. Overburden will be placed in the areas such as haul/roads and the recharge pond to bring the grade to the final reclaimed elevation. The overburden may also be spread on the 3H:1V and 2H:1V mining slope to use the excess overburden to exhaustion. This will be accomplished by using a dozer to spread the overburden material to a depth of one foot or less across the entire mining slope thus maintaining a 3H:1V and 2H:1V slope. The slope will be compacted as described in the previous paragraphs for the Water Storage Reservoir. 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. id I Ja Consulting, Inc. Journey Ventures, LLC.

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, Journey Ventures, LLC 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. V.I&T Consulting, Inc. Journey Ventures, LLC. Journey Ventures Pit DRMS 112 Permit Application 22 • • • d. Re -grade and backfill all sediment and siltation structures after mining is completed. 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. Due to the absence of sources of potential pollutants, groundwater quality monitoring is not required in this operation. 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. Journey Ventures, LLC proposes that they monitor groundwater levels through both onsite and offsite 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 Journey Ventures, LLC 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 250,000 tons per year. The total time frame to mine all phases is approximately 25 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 — 3.61 acres 6 months Phase 2 — 8.65 acres 6 months Phase 3 — 7.79 acres 1 year and 4 months Phase 4 — 6.67 acres 1 year and 6 months Phase 5 — 7.64 acres 1 year and 6 months Phase 6 — 3.18 acres 1 year and 6 months Phase 7 — 6.54 acres 2 years and 6 months Phase 8 — 19.07 acres 5 years Phase 9 — 3.60 acres 5 years Phase 10 — 5.17 acres 1 year Phase 11 — 11.05 acres 4 years and 8 months The assumed annual production rate is 250,000 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 2H: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. la Consulting, Inc. Journey Ventures, LLC.

Since this site has similar soils to the first request we received from you, I have utilized that mix for this site as well. The first seed mix is based on the original request you sent us where we attempted to utilize species that you had already included in a permit application. I have also included another seed mix, recommended by the NRCS which has fewer species and should also do well at this site. When reseeding the reclamation site, it will be important to establish a firm seedbed. Seeding of these native grasses may be done November through April. We recommend doubling the normal seeding rate for critical area seeding. We also recommend using weed -free wheat straw mulch and crimping it in as is recommended for highway right-of-way reseeding projects.

The seedbed should be well settled and firm, but friable enough that seed can be drilled at -1/2" seeding depth. Soils that have been over -compacted by traffic or equipment, especially when wet, should be tilled to break up root restricting layers, then harrowed, rolled or packed to prepare the required firm seedbed. A fluffy or too soft seedbed will place seeds too deep for proper germination. The seedbed should be reasonably free of weeds. Control competitive stands of weeds that are present before seeding by shallow tillage or by application of herbicides labeled for this purpose. Fertilizer is not required. Mulch with weed -free wheat straw and crimp into place.

Journey Ventures Pit DRMS 112 Permit Application 28 • • • EXHIBIT G Water Information Introduction The Journey Ventures Pit is located in the southeast 1/4 and the southeast % of the northwest''/ of Section 7, Township 5 North, Range 64 West of the 6th P.M., in Weld County, Colorado. The proposed mining site is located approximately 1 mile north and 1 mile west of the Town of Kersey, and approximately 1 mile north of State Highway 34 as shown in Figure Exhibit G-1. The South Platte River is approximately 2,500 feet north of the site and the North and South Branches of the Plum Ditch are adjacent to the north side of the permit boundary. The operation will consist of sand and gravel production and will impact the South Platte River in the form of depletions due to evaporation and operational losses associated with mining. Mining of the Journey Ventures Pit will last for approximately 15 to 20 years. Once reclamation is complete, a reservoir will be created with a total surface area of approximately 56-61 acres. The depth to groundwater ranges from 5 to 11 feet within the permit boundary (measured in MW -1, MW -2, and MW -5, See the attached piezometer measurements table). The site will be mined down to a depth of 55 to 80 feet after Phase 2, 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 alluvial aquifer. These impacts will cause river depletions that must be augmented. No groundwater will be exposed during the mining of Phases 1 and 2 as the ground water depths are lower than the elevation of 4594. To enable dry mining at the Journey Ventures Pit, 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 two phases are 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 50 foot by 100 foot discharge settling pond. After sediment has settled from the water it will be pumped into an irrigation lateral, which traverses the site, and eventually reaches the South Branch of the Plumb Ditch and is discharged into the South Platte 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 constructed prior to Phase 3 or at some point between Phase 3 and 11 of the mining per the reclamation plan. Water Requirements Water use at the Journey Ventures Pit will include evaporation from exposed groundwater, dust control of haul roads and stockpiles, and water retained in material removed from the site. 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 Journey Ventures pit will include groundwater exposed in the dewatering trenches and discharge settling pond. The maximum exposed surface area at the site during mining is Consulting, Inc. Journey Ventures, LLC Journey Ventures Pit DRMS 112 Permit Application 29 • • estimated at 0.38 acres. Journey Ventures, LLC 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) (1967-2007) was used. The long-term average precipitation at the Journey Ventures Pit is estimated at 14.04 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 2.93 feet. The maximum evaporative loss from the 0.38 acres is 1.11 ac -ft. Operational Loss The average annual production from the Journey Ventures Pit site is estimated at 250,000 tons. Using 4% moisture content, the total associated consumptive use for water retained in the material mined is 7.4 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 14.8 ac -ft for Phases 3-11. Consumptive Use The maximum annual consumptive use at this site during the mining operation is estimated to be 15.91 ac -ft for Phases 3-11. 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 Figure Exhibit 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.

If the proposed use of groundwater at the Journey Ventures Pit site results in material injury to surrounding wells, Journey Ventures, LLC will ensure that all necessary measures are taken to address the issues. hill Consulting, Inc. Journey Ventures, LLC Journey Ventures Pit DRMS 112 Permit Application 31 • • Water Quality An NPUES permit will be obtained from the Water Quality Control Division at the Colorado Departnient of Public Health & Environment for the Journey Ventures Pit 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 current water quality standards. Impacts' to Groundwater/Hvdroloaic Balance Journey Ventures, LLC will monitor the groundwater levels surrounding the site and provide groundwater recharge if necessary via perimeter ditches/ponds. Journey Ventures, LLC will construct these ditches/ponds in the locations where direct discharge to an existing adjacent irrigatioh 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. To summarize the mitigation process, as each phase of mining/dewatering occurs it will draw down the surrounding groundwater level to some extent. Journey Ventures, LLC 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, Journey Ventures, LLC will either implement a groundwater recharge ditch/pond near the well in order td 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 Journey Ventures, LLC (Figure Exhibit 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, Journey Ventures, LLC will either obtain a well waiver from the owner of the well, or provide an agreement with the well owner that Journey Ventures, LLC 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 Journey Ventures, LLC, 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 Journey Ventures, LLC has either installed or has access to, and the groundwater level data that has been collected for each well. .tkT (unsulting, Inc.

From: David Blauch, Senior Ecologist Aaron Eilers, Ecologist Date: September 29, 2008 RE: Wildlife Memo, Kersey Gravel Property The following provides an overview of general wildlife habitat and potential wildlife utilization of the area on or immediately adjacent to the Kersey Gravel Site (Study Area) located near the Town of Kersey, Weld County, Colorado. This evaluation is based on site visits by ERC ecologists for the purposes of wetland resource assessments, threatened and endangered species screenings and wildlife habitat reviews. General Site Description The Study Area is approximately 96 acres in size and has an average elevation of 4,600 feet above mean sea level. The Study Area is bordered by agricultural land to the north and west, County Road 51 to the east and County Road 58 to the south. The Study Area slopes to the northeast from its western boundary and the remainder of the area is largely flat. The Study Area includes two active irrigation ditches (North Branch of Plumb Ditch and South Branch of Plumb Ditch, a vegetated wetland swale, other seasonally saturated wetlands and adjacent upland areas. Vegetation within the Study Area is primarily degraded upland pasture, composed primarily of western wheatgrass (Agropyron smithii), clover (Trifolium spp.), knotweeds (Polygonum spp.) and fireweed (Kochia scoparia). Wetlands are vegetated by cattails (Typha latifolia), bulrush (Scirpus spp.) and curly dock (Rumex crispus). The majority of the Study Area is currently utilized as pasture land and also includes a home, several out buildings, an oil/gas well and access roads. Wildlife Habitat Wildlife can utilize the general landscape in a multitude of ways. Wildlife populations and individuals require specific habitats to fulfill a variety of requirements within their life histories, including food, shelter, breeding, migratory and overwintering requirements. Overall, there are features in the Study Area and in the surrounding areas that provide general habitat for local songbirds, raptors, waterfowl, amphibians, reptiles and small mammals. However habitat in the Study Area is also severely degraded by historical land use practices and the presence of non-native plants. The palustrine emergent wetland on the southern side of the Study Area is the most significant wildlife habitat feature within the Study Area. The presence of wetland habitat and a constant water source creates a relatively unique habitat in an otherwise dry agricultural landscape. The wetland may provide shelter, nesting habitat and act as a movement corridor for various small mammals, amphibians, birds and reptiles. In ERC File # 420-082 37 • addition, a black -tailed prairie dog colony (Cynomys ludovicianus) of approximately 3 acres in size is composed of disturbed uplands influenced by agricultural activities and animal grazing in the southeast corner of the Study Area. The following list represents many of the common wildlife species that may utilize habitat within the Study Area. It should be noted that this list does not include all possible species and that, for many of these species, the Study Area may only provide habitat necessary for certain portions of their life histories. Amphibians: bullfrog (Rana catesbeiana), red -spotted toad (Bufo punctatus), tiger salamander (Ambystoma tigrinum), Woodhouse's toad (Bufo woodhousii); • • Birds: American kestrel (Falco sparverius), American robin (Turdus migratorius), barn swallow (Hirundo rustica), black -billed magpie (Pica pica), black -head grosbeak (Pheucticus melanocephalus), blue grosbeak (Guiraca caerulea), blue jay (Cyanocitta cristata), Brewer's blackbird (Euphagus cyanocephalus), brown -headed cowbird (Molothrus ater), Bullock's oriole (Icterus bullockii), Cassin's sparrow (Aimophila cassinii), cliff swallow (Petrochelidon pyrrhonota), common grackle (Quiscalus quiscula), common nighthawk (Chordeiles minor), common yellowthroat (Geothlypis trichas), Eastern kingbird (Tyrannus tyrannu), grasshopper sparrow (Ammodramus savannarum), great blue heron (Ardea herodias), great -tailed grackle (Quiscalus mexicanu), horned lark (Eremophila alpestris), house wren (Troglodytes aedon), killdeer (Charadrius vociferus), lark bunting (Calamospiza melanocorys), lark sparrow (Chondestes grammacus), mallard (Anus platyrhynchos), Mississippi kite (Ictinia mississippiensis), mourning dove (Zenaida macroura), northern flicker (Colaptes auratus), northern mockingbird (Mimus polyglottos), orchard oriole (Icterus spurius), red -winged blackbird (Agelaius phoeniceus), Say's phoebe (Sayornis saya), scaled quail (Callipepla squamata), Swainson's hawk (Buteo swainsoni), western kingbird (Tyrannus verticalis), western meadowlark (Sturnella neglecta), yellow warbler (Dendroica petechia), yellow -headed blackbird (Xanthocephalus xanthocephalus); Mammals: American badger (Taxidea taxus), American beaver (Castor canadensis), black -tailed jackrabbit (Lepus californicus), black -tailed prairie dog (Cynomys ludovicianus), bobcat (Lynx rufus), common muskrat (Ondatra zibethicus), coyote (Canis latrans), deer mouse (Peromyscus maniculatus), desert cottontail (Sylvilagus audubonii), fox squirrel (Sciurus niger), hispid cotton (Sigmodon hispidus), hispid pocket mouse (Chaetodipus hispidus), hoary bat (Lasiurus cinereus), house mouse (Mus musculus), Mexican woodrat (Neotoma mexicana), mule deer (Odocoileus hemionus), northern grasshopper mouse (Onychomys leucogaster), Ord's kangaroo rat (Dipodomys ordii), pinyon mouse (Peromyscus truei), plains pocket gopher (Geomys bursarius), pronghorn (Antilocapra americana), raccoon (Procyon lotor), red fox (Vulpes vulpes), silky pocket mouse (Perognathus flavus), southern plains woodrat (Neotoma micropus), striped skunk (Mephitis mephitis), thirteen -lined ground squirrel (Spermophilus tridecemlineatus), Virginia opossum (Didelphis virginiana), western harvest mouse (Reithrodontomys 2 ERC File # 420-082 38 • megalotis), white-footed mouse (Peromyscus leucopu), white-tailed deer (Odocoileus virginianus), white -throated woodrat (Neotoma albigula), yellow -faced pocket gopher (Cratogeomys castanops); Reptiles: fence lizard (Sceloporus undulatus), gopher snake (Pituophis catenifer), lesser earless lizard (Holbrookia maculata), ornate box turtle (Terrapene ornata), plains garter snake (Thamnophis radix), racer (Coluber constrictor) and western hognose snake (Heterodon nasicus). Summary • • Degraded or heavily used agricultural land is not typically considered of high ecological value to wildlife, but this type of habitat does have beneficial values to certain species. The Study Area provides "open space" which, among other benefits, can provide individual species with appropriate acreage to fulfill home range and territorial requirements. In addition, open space can provide foraging and hunting grounds, refuge, and nesting habitat to various degrees. However, historic land use practices within the Study Area have limited the development of natural vegetation communities by perpetuating the spread of non-native species and preventing the development of a mixed native vegetation community, with species diversity and an assortment of vegetative structural classes. The effect of these practices limits the overall quality and utilization of potential wildlife habitat. Although the open space provided by the Study Area may cumulatively contribute to increased regional wildlife use, by itself, it does not contribute any exceptional wildlife habitat characteristics. 3 ERC File # 420-082 39 • • • A Ecological Resource Consultants, Inc 5672 Juhls Drive —Boulder, Colorado —80301-303.679.4820 Screening Report of Threatened, Endangered and Species of Concern Kersey Gravel Site Weld County, Colorado Prepared for: J.C.

Introduction • • • This report summarizes the findings of a screening for threatened, endangered species and species of concern (TES) as well as TES potential habitat which may exist on or immediately surrounding the Kersey Gravel Site (Study Area). The screening is intended as a rapid assessment to determine the potential existence and/or presence of habitat for TES. The screening included an onsite evaluation of potential species and habitat, as well as a review of available databases and literature. This screening does not include a presence/absence determination, which could include detailed species surveys, population inventories or trapping evaluations. The screening was conducted at the request of the project engineer, Mr. J.C. York (J&T Consulting, Inc., 1400 W 122nd Avenue — Suite 120, Westminster, CO 80234). Ecological Resource Consultants, Inc. (ERC) conducted a screening of the Study Area which is located northwest of the Town of Kersey, Colorado, west of US 34 and south of US 37. The Study Area can be accessed by taking Interstate 25 north towards Ft. Collins to US 34 east. Take US 34 east to County Road 53, head north on County Road 53 and turn west on County Road 58. The Study Area is located northwest of the intersection of County Roads 58 and 51. More specifically, the Study Area is located in the eastern half of Section 7, Township 5 North, Range 64 West in Weld County, Colorado (Latitude 40.242690 North, Longitude 104.350559 West). A Study Area location map is included in this report as Figure 2. ERC: conducted an onsite assessment of the Study Area on April 28, 2008 to identify and document the presence of natural vegetation communities, general wildlife, potential habitat and TES. General Site Description The Study Area is approximately 96 acres in size and has an average elevation of 4,600 feet above mean sea level. The Study Area is bordered by agricultural land to the north and west, County Road 51 to the east and County Road 58 to the south. The Study Area slopes to the northeast on the western side of the Study Area and the remainder of the area is largely flat. The Weld County Soil Survey (USDA SWS, 2007) maps the soils within the Study Area as Altvan loam, Aquolls and Aquents, and Ustic Torriorthents, all of which are listed as a hydric soils of Colorado (NRCS, 2007). The Study Area includes an active irrigation ditch, a vegetated Swale, isolated wetland and adjacent upland areas. The majority of the Study Area is currently utilized as pasture land and also includes a home, several out buildings, an oil well and several access roads. The wetlands within the Study Area are dominated by three square, curly dock, cattail and bulrush. The upland areas immediately adjacent to the wetlands are dominated by salt grass, western wheatgrass and kochia. Wildlife Assessment Methodology ERC conducted a literature review as part of initial data collection for preparation of the TES screening. Among others, ERC reviewed the following literature sources; Colorado Division of Wildlife (CDOW) information, Colorado Natural Heritage Program databases and the US Fish and Wildlife Service's Federal Register. A field inspection was subsequently conducted in order to assess conditions within the Study Area. The Study Area was traversed, and ERC personnel assessed and documented vegetation cover types, wildlife observations, evidence of wildlife use and general Study Area characteristics. 2 42 Kersey Gravel Site TES Screening Ecological Resource Consultants. Inc. Upon review of all available resources, including literature and field inspections, ERC made the following determinations with regard to wildlife usage and habitat within the Study Area. General Wildlife Habitat Wildlife can utilize the general landscape in a multitude of ways. Wildlife can use specific habitats as areas of permanent inhabitance, seasonal inhabitance, breeding grounds, migratory routes, for foraging purposes or as a temporary shelter. Degraded agricultural land is not typically considered of high ecological value to wildlife, but this type of habitat does have beneficial values to certain species. These lands can provide foraging and hunting grounds, refuge, nesting, and provide general"open space". The palustrine emergent wetland on the southern side of the Study Area is the most significant wildlife habitat feature within the Study Area. The presence of wetland habitat and a constant water source creates a relatively unique habitat in an otherwise dry agricultural landscape. The wetland may provide shelter, nesting habitat and act as a movement corridor for various small mammals, amphibians, bird and reptiles. Historic land use practices have limited the development of natural vegetation communities within the Study Area. The effect of these practices limits the overall quality of potential wildlife habitat. Overall, there are features on the Study Area and the surrounding area that provide general habitat for local songbirds, raptors, waterfowl, amphibians, reptiles and small mammals, however habitat in this Study Area is severely degraded by historical land use practices and the presence of non- native plants. 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 (Sturna vulgaris), house sparrow (Passer domesticus) and rock dove (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 US Fish and Wildlife Service (USFWS) Region 6. • Migratory birds exist and likely nest within the Study Area. The wetland and upland areas likely provide habitat for migratory birds. Such birds are protected under the MBTA, and killing or possession of these birds (or their parts and nests) is prohibited under the MBTA. Disturbance of active nests is prohibited. • Bald eagles likely use the nearby South Platte River and riparian corridor located approximately 0.5 miles north of the Study Area. However, no bald eagles or evidence of bald eagles were observed utilizing the Study Area at the time of inspection. Species Protected Under the Endangered Species Act of 1973 The Endangered Species Act (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, 3 43 • • • Kersey Gravel Site TES Screening Ecological Resource Consultants, Inc. 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 summary charts identifying "endangered" or "threatened" species protected under the ESA for each county of Colorado (USFWS Summary Charts 2003). ERC reviewed the Summary Chart for Weld County and determined that the species identified below have the potential to exist within the vicinity of the Study Area. Federally listed threatened or endangered species not identified below are not known to exist within vicinity of the Study Area or have specific habitat requirements that are not common in the vicinity of the Study Area. • Black -footed ferret (Mustela nigripes) — Endangered • Colorado butterfly plant (Guerra neomexicana spp. Coloradensis) — Threatened • Interior Least tern (Sternula antillarum)— Endangered • Pallid Sturgeon (Scaphirhynchus albus) — Endangered • Piping plover (Charadrius melodus)— Threatened • Preble's meadow jumping mouse (Zapus hudsonius prebei) — Threatened • Ute ladies' —tresses orchid (Spiranthes diluvialis) — Threatened • Whooping crane (Grus americana)— Endangered Black -footed ferret The black -footed ferret (Ferret) is listed as federally endangered under the ESA. This mammal is found in shortgrass to midgrass prairies and semi -desert shrublands, and is always located near a prairie dog town. Large prairie dog colonies are typically needed to support one ferret. USFWS guidelines state that the minimum acreage of prairie dog habitat needed to support a black -footed ferret is 80 acres of black -tailed prairie dog towns and 200 acres of white-tailed prairie dog towns (http://www.fs.fed.us/r2/nebmska/gpng/reports/ferretguidelines.html). Ferrets are 20 to 25 inches in length, weigh approximately 1 to 1.5 pounds. The Ferret is characterized by a black mask across the face, a brownish head, black feet and legs, and a black tipped tail. The Ferret's short, buff -colored fur becomes lighter on the underside of their bodies. Females have one litter of three to four kits each year. Kits do not emerge from the underground prairie dog burrows until they are six weeks old, and remain with their mothers for two to three months. Breeding occurs from February to March. The main prey for this species is prairie dogs, mice, ground squirrels, birds, reptiles and insects. Predators include owls, golden eagles, coyotes, badgers and domestic dogs. This species is most active at night; daylight activity is limited to the first five hours after sunlight. Above -ground activity increases in the winter season (October -January). • The black -tailed prairie dog colonies located within and adjacent to the Study Areas don't appear to be sufficient in size to support a Ferret population. Due to the fragmented nature of the Study Areas and surrounding agricultural land use, Ferrets are highly unlikely to be found within or adjacent to the Study Areas. Any change in land use should not adversely affect the continued existence or potential habitat of this species. Colorado butterfly plant 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 -semi 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). Kersey Gravel Site TES Screening Ecological Resource Consultants, Inc. • No Colorado butterfly plants or potential habitat was observed in the Study Area. The Study Area's fallow agricultural lands and wetlands do not exhibit typical habitat of the Colorado butterfly plant. Due to historic use of the Study Area, the rangelands onsite are highly degraded. Wetlands within the Study Area are reliant on agricultural water and fluctuating ground water levels and do not provide a consistently moist environment conducive to the plant. Neither individuals nor potential habitat for the Colorado butterfly plant were observed on or immediately surrounding the Study Area. Any change in land use in the Study Area should not adversely affect the continued existence or available habitat of this species. Interior least tern The interior least tern (Tern) is listed as federally endangered under the ESA. The least tern is a small shorebird identified by a black -capped crown, white forehead, grayish back, white underparts, yellow legs, and a black -tipped bill. This avian migrant species breeds in North America and winters in South America. Tern habitat consists of sand and gravel areas located above the high water mark. Suitable nesting habitat is sparsely vegetated with sand or gravel substrate, which is maintained by flooding and scouring. Nests consist of small scrapes in the sand that must stay dry. Two to three eggs are typically laid each year, with incubation times ranging from 19 to 25 days. Chicks vary in color from white to tan with black spots or streaks across their back and top of the head. Because least terns are sensitive to human disturbance, a buffer zone of at least 0.25 mile around active nesting colonies is recommended for any recreation or construction activities. It is the smallest member of the tern family with a wingspan of 20 inches. Least terns can be distinguished from all other terns by their combination of a black crown, white forehead, and a variable black -tipped yellow bill. • The Study Area does not contain gravel bars and sandy shorelines that are typically found along or within large rivers. The probability of Terns nesting within the Study Areas is highly unlikely. Any change in land use within the Study Areas should not adversely affect the continued existence or available habitat of this species. • Any future project that results in water depletions to the Platte River Basin may potentially be considered an adverse effect to this species. If the proposed project results in water depletions to the Platte River Basin, ESA Sec. 7 Consultation with the USFWS may be required. Pallid Sturgeon The pallid sturgeon (Sturgeon) is listed as federally endangered under the ESA. These fish are found in large, deep, turbid, swift river channels and associated with firm sand/gravel substrate. The Sturgeon has a long and slender, shovel like snout that is flattened. Adults can grow 73 inches in length and weigh up to 85 pounds. The spawning period occurs from June through August. Males mature between 7-9 years, with up to 3 years between spawns. Females mature between 7-15 years, with up to 10 -year intervals between spawning. Pallid sturgeons are long lived, with individuals perhaps reaching 60 years of age or more. The Sturgeon has suffered significant habitat loss and modification from construction of dams and channelization of rivers. Commercial fishing and environmental contaminants may have also played a role in the pallid sturgeon's decline. Hybridization with the more common shovelnose sturgeon is a threat to the species and may be due to habitat modifications. • The Sturgeon has historically been found along the Platte River in Nebraska to the Missouri River. The drainages found within the Study Area does not provide suitable habitat for this species. Any change in land use within the Study Area should not adversely affect the continued existence or available habitat of this species. 5 45 Kersey Gravel Site TES Screening Ecological Resource Consultants, Inc. • Any future project that results in water depletions to the Platte River Basin may potentially be considered an adverse effect to this species. If the proposed project results in water depletions to the Platte River Basin, ESA Sec. 7 Consultation with the USFWS may be required. Piping Plover The piping plover (Plover) is listed as federally threatened under the ESA. The piping plover is an imperiled migratory shorebird that spends winter months in southeastern North America and the Caribbean Islands, and breeds from southern Canada to northeastern and central regions of the United States. The Colorado Plover population is a breeding population that typically arrives around the beginning of April and leaves by the end of May. They are normally found inhabiting beaches, lake shores, marshes, mudflats, and other wetland areas. In Colorado, nesting habitat consists of sandy lakeshore beaches, sandbars of riverbeds, and sandy wetland pastures. Preferred habitat is sparsely vegetated, typically less than five percent. Nest sites are simple depressions or scrapes in the sand of approximately 2 to 3 inches in diameter, often lined with pebbles, shells or driftwood to enhance the camouflage effect. The average clutch size is four eggs and young hatch about 27 to 31 days after laying eggs. Nest success depends heavily upon camouflage. Piping plovers are only about 7 inches long with round dark eyes, and stubby bills. Adult males have a plain white forehead with a dark band across the front of the crown from eye to eye and black shoulder patches. The piping plover feeds on worms, fly larvae, beetles, crustaceans, mollusks and other invertebrates that it finds along open shorelines of reservoirs, river islands and adjacent sand pits. • The Study Area does not contain gravel bars and sandy shorelines that are typically found along or within large rivers. The probability of Plovers nesting within the Study Area is highly unlikely. Any change in land use within the Study Area should not adversely affect the continued existence or available habitat of this species. • Any future project that results in water depletions to the Platte River Basin may potentially be considered an adverse effect to this species. If future land use changes result in water depletions to the Platte River Basin, ESA Sec. 7 Consultation with the USFWS may be required. Preble's meadow lumping mouse On May 13, 1998 the US Fish and Wildlife Service issued a final rule to list the Preble's meadow jumping mouse (Mouse) as a federally threatened species under the ESA. The Mouse's range extends from southwestern Wyoming through eastern Colorado generally below 7,600 feet. Armstrong et. al. (1997) described typical Mouse 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" (Fish and Wildlife Service 1999). This species is known to regularly travel into adjacent uplands to feed and hibernate. The Mouse hibernates in an underground burrow from September to May. The Mouse bears two to three litters per year, averaging five young per litter, in a grass -lined nest. In general, Mouse surveys are recommended for areas with suitable habitat in Weld County below 7,600 feet and within 350 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 Mice or potential habitat was observed in the Study Area. The Study Area does not contain undisturbed diverse riparian vegetation typically associated with the Mouse. No specimens or habitat were observed during the onsite evaluation. No known populations or designated Critical Mouse Habitat have been identified in or near the Study Area. The Study Area contains minimal shrub diversity and is dominated by a grass/non-native ecosystem. The current habitat conditions are not conducive to Mouse occupation. Any 6 46 Kersey Gravel Site TES Screening Ecological Resource Consultants, Inc. change in land use in Study Area should not adversely affect the continued existence or available habitat of this species. Ute ladies' -tresses orchid The the ladies' -tresses orchid (Orchid) is listed as federally threatened under the ESA. The Orchid occurs in seasonally moist soils and wet meadows near springs, lakes, or perennial streams and their associated floodplains below 6,500 feet elevation in certain areas in 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. 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. • No Orchids or potential habitat was observed in the Study Area. The Study Area contains wetland regimes dictated by irrigation water, upland prairie dog colonies and agricultural/pasture lands which are not habitat characteristics conducive to the Orchid. Any change in land use to the Study Area should not adversely affect the continued existence or potential habitat of this species. Whooping crane The whooping crane (Crane) is listed as federally endangered under the ESA. Cranes typically live in mudflats around reservoirs and in agricultural areas. While wintering they live on salt flats that are dominated by coastal salt grass. Their nesting grounds are wetland communities dominated by bulrush. In Colorado, the crane only occurs as a migrant. Within the state, whooping cranes are most commonly seen stopping over in the San Luis Valley for four to six weeks during February and March and in the western valleys, especially Mesa, Delta and Gunnison Counties (CDOW). The adult crane is a relatively large white bird approximately 50 to 56 inches tall with a wingspan of 87 to 90 inches and an average weight of 15 pounds. The bird is distinguished by its outstretched neck in flight. Primary threats to the Crane include habitat loss due to agriculture, human disturbance of nesting areas, uncontrolled hunting, water diversions/depletions, habitat contamination and fragmentation. • The Study Area does not contain mudflat habitat typical of whooping crane habitat and whooping cranes rarely occur in this part of the state. In addition, Cranes are rarely seen in Colorado except during migration in the San Luis Valley. Cranes have not been seen in Colorado since 2002. Any change in land use should not adversely affect the continued existence or potential habitat of this species. • Any future project that results in water depletions to the Platte River Basin may potentially be considered an adverse effect to this species. If the proposed project results in water depletions to the Platte River Basin, ESA Sec. 7 Consultation with the USFWS may be required. State Endangered and Threatened Species Species identified as State endangered or threatened are protected by the Colorado Division of Wildlife (CDOW) 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 CDOW 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 (CNHP, 1999). Species of 7 47 Kersey Gravel Site TES Screening Ecological Resource Consultants, Inc. Special Concern are not protected under State regulations but the `take' of individuals and disturbance of their habitat is strongly discouraged. The following State listed species were screened as potential inhabitants of the Study Area based on general habitat requirements, Colorado Natural Heritage Program lists by county (CNHP, August 2004), and the CDOW tables (revised April 2003), Colorado Listing of Endangered, Threatened, and Wildlife Species of Special Concern. ERC evaluated species listed by CDOW that are considered Endangered or Threatened and identified the burrowing owl as potentially occurring within the Study Area. Burrowing Owl The burrowing owl (Owl) is listed as a state threatened species in Colorado. The Owl is a small (length of 24 cm), long-legged, boldly spotted and barred with brown and white. 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 thirty days. The owlets usually run and forage at four weeks and fly at six. Primary threats to this species existence are habitat loss due to intensive agriculture, habitat degradation and fragmentation due to control of burrowing mammals and predation by cats and dogs. • The prairie dog colonies located with the Study Area exhibit characteristics of potential Owl nesting habitat. No Owl individuals were observed on the Property and the presence of Owls is unlikely. However, prior to any disturbance to prairie dog colony, ERC recommends a presence/absence survey be conducted to ensure that no Owls are present. Summary ERC has conducted this screening for threatened, endangered and species of concern for the Study Area. The screening is intended as a rapid assessment to determine the potential existence and'or presences of habitat for TES. The following provides key items identified as part of this screening. • Migratory birds exist and likely nest in the Study Area. Such birds are protected under the MBTA, and killing or possession of these birds (or their parts and nests) is prohibited under the MBTA. Future land use changes should not impact active nests. If vegetation removal occurs during the breeding season, April through August, ERC recommends a breeding bird survey(s). • No threatened or endangered species populations or habitat protected under the Endangered Species Act were identified directly in the Study Area. However, any future land use changes in the Study Area that are determined as a water depletion to the South Platte River may potentially be considered an adverse effect to the interior least turn, pallid sturgeon, piping plover and whooping crane. If future land use changes are determined to be a water depletion to the South Platte River, ESA Section 7 Consultation with the USFWS may be required. • Upon review of species identified as State endangered or threatened, protected by the Colorado Division of Wildlife (CDOW) under Colorado Statute Title 33, only the burrowing owl (Athene cunicularia) was identified as potentially present in the Study Area. This owl is listed as a state threatened species. The prairie dog colonies located in the Study Area exhibit characteristics of potential owl habitat. However, no owl individuals were observed in the 8 48 Kersey Gravel Site TES Screening Ecological Resource Consultants. Inc. Study Area during the initial site investigation or any of the three burrowing owl surveys performed between June 9 and June 25, 2008.

The survey is intended to determine the presence or absence of burrowing owls located within an existing black - tailed prairie dog (Cynomys ludovicianus) colony along the southern boundary of the Study Area. The survey was conducted at the request of the project engineer, Mr. J.C. York (J&T Consulting, Inc., 1400 W 122"d Avenue — Suite 120, Westminster, CO 80234). Ecological Resource Consultants, Inc. (ERC) conducted a threatened and endangered species (TES) screening dated April 28, 2008 which identified potential burrowing owl habitat associated with a small black -tailed prairie dog colony within the Study Area. To determine the presence or absence of burrowing owls, a screening survey was conducted at the Study Area, located in the Town of Kersey, Colorado; north of US 34 and west of US 37. The Study Area can be accessed by taking Interstate 25 north towards Ft. Collins to US 34 east. Take US 34 east to County Road 53, head north on County Road 53 and turn west on County Road 58. The Study Area is located northwest of the intersection of County Roads 58 and 51. More specifically, the Study Area is located in the eastern half of Section 7, Township 5 North, Range 64 West in Weld County, Colorado (Latitude 40.242690 North, Longitude 104.350559 West). A Study Area location map is included in this report as Figure I. 2.0 General Site Description • • The Study Area is approximately 96 acres in size and has an average elevation of 4,600 feet above mean sea level. The Study Area is bordered by agricultural land to the north and west, County Road 51 to the east and County Road 58 to the south. The Study Area slopes to the northeast from its western boundary and the remainder of the area is largely flat. The black -tailed prairie dog colony of subject of this survey is located within the southeast corner the Study Area, immediately upgradient of a palustrine emergent wetland drainage. The colony is approximately 3 acres in size and is composed of disturbed uplands influenced by agricultural activities and animal grazing. 3.0 Burrowing Owl: Habitat and Life History The burrowing owl (Owl) is a State -listed threatened species in Colorado. The Owl is small (length of 24 cm), long-legged, boldly spotted and barred with brown and white. Preferred nesting habitat consists of abandoned burrows in active prairie dog colonies, with open, heavily grazed, native mixed -grass prairie surrounding the burrow (McDonald et al. 2004). Owls utilize nesting habitat between March and October and usually can be observed on low perches such as fence posts, dirt mounds or the ground. Clutch sizes of this Owl average six to seven owlets and incubation lasts up to thirty days. The owlets usually run and forage at four weeks and fly at six. Primary threats to this species include habitat loss due to intensive agriculture; habitat degradation and fragmentation due to control of burrowing mammals; and predation by cats and dogs. Species identified as State endangered or threatened are protected by the Colorado Division of Wildlife (CDOW) under Colorado Statute Title 33. State regulations prohibit "any person to take, 2 59 • 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. As indicated in the ERC TES report, the burrowing owl is the only State listed species of Endangered or Threatened wildlife potentially occurring within the Study Area. 4.0 Wildlife Assessment Methodology To implement this survey, ERC used the "Recommended Survey Protocol and Actions to Protect Nesting Burrowing Owls" (Protocol), published by the Colorado Division of Wildlife (CDOW 2007). The Protocol recommends conducting at least three separate surveys between March 15`" and October 31' to increase the likelihood of Owl detection. Surveys are conducted in the early morning (1/2 hour before sunrise until 2 hours after sunrise) and/or early evening (2 hours before sunset until '/3 hour after sunset). Surveys should only be conducted on days with little or no wind and no precipitation. This survey was conducted using both the passive and call -broadcast methods. Using the passive survey method, the observer listens and visually scans the area to detect any present owls. Passive surveys are conducted for 10 minutes at each location. Using the call -broadcast method, the observer broadcasts the primary call (coo -coo) and the alarm call (quick -quick -quick) to elicit a response from the owl. The observer uses the following 10 -minute timeline for incorporating call - broadcast methods into the survey: • • • 3 minutes of silence • 30 seconds call -broadcast of primary call • 30 seconds of silence • 30 seconds call -broadcast of primary call • 30 seconds of silence • 30 seconds call -broadcast of alarm call • 30 seconds of silence • 4 minutes of silence During the first ERC site visit, only the passive survey method was used. During the second and third site visits, the observer walked a 500 -foot transect southeast to northwest across the prairie dog colony, stopping at 100 -foot intervals for passive or call -broadcast surveys. Each 100 -foot interval was considered a transect survey point. Passive survey methods were used at transect points I, 3, and 5. Call broadcast methods were used at transect points 2 and 4. 3 60 • 5.0 Results Surveys were conducted on three separate occasions. The first site visit began at 6:15 a.m. on June 6, 2008. Using the passive survey method outlined in the protocol, observers listened and visually scanned the prairie dog colony to detect any Owls that may be present. No Owls were heard or observed. The second site visit began at 5:50 a.m. on June 24, 2008. To increase the likelihood of detecting Owls, call -broadcast methods and passive survey methods were used. Passive surveys were performed at transect points I, 3 and 5. Call -broadcast surveys were performed at transect points 2 and 5. No Owls were heard or observed. The third site visit began at 5:30 a.m. on June 25, 2008. Passive surveys were performed at transect points I, 3 and 5. Call -broadcast surveys were performed at transect points 2 and 5. No Owls were heard or observed. Burrowing owls typically arrive on Colorado breeding grounds in late March or early April, with nesting beginning a few weeks later. Active nesting and fledging can be expected from late March through early August. Adults and young may remain at prairie dog towns until migrating to wintering grounds in late summer or early autumn (CDOW 2007). Based on the results of this survey, the black -tailed prairie dog colony at the Kersey Gravel Site does not appear to provide habitat for burrowing owl individuals or populations at this time. The existing colony is also not likely to provide Owl habitat in the future. However, the seasonally transient nature of this species does not guarantee future absence. This report could be submitted to the CDOW for formal clearance as of the 2008 breeding season. • 6.0 References Colorado Division of Wildlife. 2007.

(ERC) previously completed the below listed environmental studiles for a parcel of land, referred to as the Kersey Gravel Site, located on approximately 96 - acres in the eastern half of Section 7, Township 5 North, Range 64 West in Weld County, Colorado. Environmental Studies completed by ERC include: • Wetland Delineation Report for the Kersey Gravel Site Weld County Colorado, July 10, 2008, • Screening Report of Threatened, Endangered and Species of Concern for the Kersey Gravel Site, Weld County, CO May 9, 2009, • Burrowing Owl Clearance Survey for the Kersey Gravel Site, Weld County, Colorado July 7, 2008, and • Wildlife Memo, Kersey Gravel Site, September 29, 2008. These studies specifically addressed environmental condition for a study area defined by LOT B. At the request of J&T Consulting, ERC provides this letter to include LOT A as part of the overall study area, which was previous considered an outlot. Although LOT B was the defined study area for the environmental studies, LOT A was incidentally evaluated due to its proximity and connectivity to LOT B. Refer to the attached Recorded Exemption Plat for specific boundary layout. LOT A is an approximately 11.86 -acre parcel situated in the center of LOT B along the western property line of LOT B. LOT A is a relatively flat, active pasture land towards the eastern half. A small residential house, several barns and farm structures exist along the western half. Along western property line of LOT A, topography becomes much steeper. ERC conducted a field visit of LOT A on November 6, 2008. Weather was cold and windy, vegetation was entering dormancy, soils where thawed and the ground surface was visible. ERC traversed LOT A, to determine any conditions that may indicate the presences of wetlands, threatened, endangered and species of concern or wildlife concerns as address in the previously completed environmental studies. Thel following provides an overview of findings for LOT A: • Wetl nds The physical characteristics of LOT A are consistent with the findings described as Uplands in the Wetland Delineation Report. The entire LOT is comprised of dry disturbed lands resulting from agricultural activities and grazing. Dominant vegetation consists of wheatgrass (Pascopyron smithii), salt grass (Distictalis spicata), sweet clover (Trifolium sp.) and kochia (Kochia scopari), all considered non -wetland plants. Hydric soil and wetland hydrology indicators were not observed. In summary, LOT A is considered disturbed upland habitat and does not contain any wetland habitat. Threatened, Endangered and Species of Concern The physical characteristics of LOT A are consistent with the findings Summary provided as part of the LOT B Screening Report of Threatened, Endangered and Species of Concern. Findings addressed in the Summary should be considered applicable to LOT A. However, because no prairie dog colonies are present in LOT A, the presences of burrowing owls is not a concern. 31.14ilk The physical characteristics of LOT A are consistent with the findings presented in the Wildlife Memo for LOT B. Findings addressed in the Wildlife Memo should be considered applicable to LOT A. • PHOTO 1. View across center of upland pasture meadow from the western side of LOT B towards the east (11-6-08). PHOTO 2. View across center of upland pasture meadow towards the residential home site from the eastern side of LOT B towards the west (11-6-08). In summary, environmental studies completed for LOT B should also be considered applicable for LOT A. Ecological Resource Consultants, Inc. David J.

The map unit descriptions in this report, 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. The Map Unit Description (Brief, Generated) report displays a generated description of the major soils that occur in a map unit. Descriptions of non -soil (miscellaneous areas) and minor map unit components are not included. This description is generated from the underlying soil attribute data. Additional information about the map units described in this report is available in other Soil Data Mart reports, which give properties of the soils and the limitations, capabilities, and potentials for many uses. Also, the narratives that accompany the Soil Data Mart reports define some of the properties included in the map unit descriptions.

Depth to the upper and lower boundaries of each layer is indicated. Texture is given in the standard terms used by the U.S. Department of Agriculture. These terms are defined according to percentages of sand, silt, and clay in the fraction of the soil that is less than 2 millimeters in diameter. "Loam," for example, is soil that is 7 to 27 percent clay, 28 to 50 percent silt, and less than 52 percent sand. If the content of particles coarser than sand is 15 percent or more, an appropriate modifier is added, for example, "gravelly" Classification of the soils is determined according to the Unified soil classification system (ASTM, 2005) and the system adopted by the American Association of State Highway and Transportation Officials (AASHTO, 2004). The Unified system classifies soils according to properties that affect their use as construction material. Soils are classified according to particle -size distribution of the fraction less than 3 inches in diameter and according to plasticity index, liquid limit, and organic matter content. Sandy and gravelly soils are identified as GW, GP, GM, GC, SW, SP, SM, and SC; silty and clayey soils as ML, CL, OL, MH, CH, and OH; and highly organic soils as PT. Soils exhibiting engineering properties of two groups can have a dual classification, for example, CL -ML. The AASHTO system classifies soils according to those properties that affect roadway construction and maintenance. In this system, the fraction of a mineral soil that is less than 3 inches in diameter is classified in one of seven groups from A-1 through A-7 on the basis of particle -size distribution, liquid limit, and plasticity index. Soils in group A-1 are coarse grained and low in content of fines (silt and clay). At the other extreme, soils in group A-7 are fine grained. Highly organic soils are classified in group A-8 on the basis of visual inspection. If laboratory data are available, the A-1, A-2, and A-7 groups are further classified as A -1-a, A -1-b, A-2-4, A-2-5, A-2-6, A-2-7, A-7-5, or A-7-6. As an additional refinement, the suitability of a soil as subgrade material can be indicated by a group index number. Group index numbers range from 0 for the best subgrade material to 20 or higher for the poorest. Rock fragments larger than 10 inches in diameter and 3 to 10 inches in diameter are indicated as a percentage of the total soil on a dry -weight basis. The percentages are estimates determined mainly by converting volume percentage in the field to weight percentage. Percentage (of soil particles) passing designated sieves is the percentage of the soil fraction less than 3 inches in diameter based on an ovendry weight. The sieves, numbers 4, 10, 40, and 200 (USA Standard Series), have openings of 4.76, 2.00, 0.420, and 0.074 millimeters, respectively. Estimates are based on laboratory tests of soils sampled in the survey area and in nearby areas and on estimates made in the field. Liquid limit and plasticity index (Atterberg limits) indicate the plasticity characteristics of a soil. The estimates are based on test data from the survey area or from nearby areas and on field examination. • USDA a Natural Rekources Conservat n Service Web Soil Survey 2.0 National Cooperative Soil Survey 10252008 Page 1 of 4 75 Engineering Properties —Weld County, Colorado, Southern Part Journey Ventures Pit References: American Association of State Highway and Transportation Officials (AASHTO). 2004.

The estimates are used in land use planning that involves engineering considerations. Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The four hydrologic soil groups are: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (ND, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Surface runoff refers to the loss of water from an area by flow over the land surface. Surface runoff classes are based on slope, climate, and vegetative cover. The concept indicates relative runoff for very specific conditions. It is assumed that the surface of the soil is bare and that the retention of surface water resulting from irregularities in the ground surface is minimal. The classes are negligible, very low, low, medium, high, and very high. The months in the table indicate the portion of the year in which a water table, ponding, and/or flooding is most likely to be a concern. Water table refers to a saturated zone in the soil. The water features table indicates, by month, depth to the top (upper limit) and base (lower limit) of the saturated zone in most years. Estimates of the upper and lower limits are based mainly on observations of the water table at selected sites and on evidence of a saturated zone, namely grayish colors or mottles (redoximorphic features) in the soil. A saturated zone that lasts for less than a month is not considered a water table. USDA Natural Resources Conservation Service Web Soil Survey 2.0 National Cooperative Soil Survey 10/25/2008 Page 1 of 4 79 Water Features —Weld County, Colorado, Southern Part Journey Ventures Pit Ponding is standing water in a closed depression. Unless a drainage system is installed, the water is removed only by percolation, transpiration, or evaporation. The table indicates surface water depth and the duration and frequency of ponding. Duration is expressed as very brief if less than 2 days, brief if 2 to 7 days, long if 7 to 30 days, and very long if more than 30 days. Frequency is expressed as none, rare, occasional, and frequent. None means that ponding is not probable; rare that it is unlikely but possible under unusual weather conditions (the chance of ponding is nearly 0 percent to 5 percent in any year); occasional that it occurs, on the average, once or less in 2 years (the chance of ponding is 5 to 50 percent in any year); and frequent that it occurs, on the average, more than once in 2 years (the chance of ponding is more than 50 percent in any year). Flooding is the temporary inundation of an area caused by overflowing streams, by runoff from adjacent slopes, or by tides. Water standing for short periods after rainfall or snowmelt is not considered flooding, and water standing in swamps and marshes is considered ponding rather than flooding. Duration and frequency are estimated. Duration is expressed as extremely brief if 0.1 hour to 4 hours, very brief if 4 hours to 2 days, brief if 2 to 7 days, long if 7 to 30 days, and very long if more than 30 days. Frequency is expressed as none, very rare, rare, occasional, frequent, and very frequent. None means that flooding is not probable; very rare that it is very unlikely but possible under extremely unusual weather conditions (the chance of flooding is less than 1 percent in any year); rare that it is unlikely but possible under unusual weather conditions (the chance of flooding is 1 to 5 percent in any year); occasional that it occurs infrequently under normal weather conditions (the chance of flooding is 5 to 50 percent in any year); frequent that it is likely to occur often under normal weather conditions (the chance of flooding is more than 50 percent in any year but is less than 50 percent in all months in any year); and very frequent that it is likely to occur very often under normal weather conditions (the chance of flooding is more than 50 percent in all months of any year). The information is based on evidence in the soil profile, namely thin strata of gravel, sand, silt, or clay deposited by floodwater; irregular decrease in organic matter content with increasing depth; and little or no horizon development. Also considered are local information about the extent and levels of flooding and the relation of each soil on the landscape to historic floods. Information on the extent of flooding based on soil data is less specific than that provided by detailed engineering surveys that delineate flood -prone areas at specific flood frequency levels.

The site is currently actively grazed agricultural pasture land. ERC's wetland delineation report is attached which includes descriptions of the general vegetation found on the site and wetlands found in the area. Note that jurisdictional wetlands were found on the site. A letter from the US Army Corps of Engineers is attached that states that they what they did concur with the majority of the ERC wetland delineation report and did not concur with the ERC wetland delineation of Wetland A. Journey Ventures, LLC will not be mining in the areas of the existing irrigation ditches (Plumb Ditch South and North Branches) or in the area of Wetland A. The wetlands that could be affected by the mining operation are at Wetland B. Prior to mining Phase 8 Journey Ventures, LLC will apply for an individual 404 permit to mitigate for impacts to Wetland B that will require approval from the Army Corps of Engineers. At this time we would anticipate the mitigation to be buying wetland bank credits for approximately 1.53 acres. The wetland bank credits could be purchased through Mile High Wetland Bank. We have contacted Ms. Laurie Rink with Mile High Wetland Group, LLC and they have available credits to purchase. Vl J&T Consulting. Inc. Journey Ventures, LW.

As a result of this review it was determined that since the bottom elevation of Wetland A is at the same elevation at one location and higher at other locations than the bottom of the North Branch Plum Ditch, water from these higher elevations of Wetland A would potentially seep under ground into the North Branch Plum Ditch. Based on this determination, this higher elevation portion of Wetland A is considered hydrologically adjacent to the North Branch Plum Ditch. This makes the high elevation areas of Wetland A jurisdictional, which includes the remaining contiguous areas of Wetland A as jurisdictional. My August 18, 2008 Approved Jurisdictional letter based on the August 18, 2008 Appro\ ed JD for Wetland A is considered accurate for this project.

CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarises information regarding characteristics of the tributary and its adjacent wetlands. if any, and it helps determine whether or not the standards for jurisdiction established under Ripsaws have been met. The agencies will assert jurisdiction over non -navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs). i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. lithe aquatic resource is not a TNW. but has year-round (perennial) flow. skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section 111.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody4 is not an RPW. or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. lithe tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section iii.B.2 for any onsite wetlands, and Section 111.6.3 far all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section IILC below. I.

(ERC) for the Study Area. The delineation was conducted at the request of J&T Consulting, Inc. (Contact: Mr. J.C. York, 1400 W. 122"d Avenue, Suite 120, Westminster, CO 80234). ERC conducted the on -site portion of the wetland delineation on April 28, 2008. A follow up site visit with Mr. Terry McKee of the U.S. Army Cops of Engineers (USACE) was completed on June 9, 2008. During the follow up site visit Mr. McGee indicated that the site may have been previously delineated and a jurisdictional dete rmination made. Upon further review, Mr. McKee notified ERC that the site had been previously reviewed, twice in 2001 and 2002. However, the previous studies and jurisdictional determinations are expired and no longer valid. 2.0Study Area Location Th Study Area is located northwest of the Town of Kersey, Colorado, north of U.S. Highway (U ) 34 and south of US 263, in Weld County. This general region is characterized by broadly roll•ng topography. The major feature in this region is the South Platte River Valley, which ext nds across the southwestern and central parts. The major streams in this area generally oc py wide valleys that are separated by broad, gently rolling to flat interstream divides. Most of the area is used as irrigated cropland. Th Study Area can be accessed by taking Interstate 25 north to exit 257A — US 34 east. Take US 34 east to County Road (CR) 53, head north on CR 53 and turn west on CR 58. The Study Area is located northwest of the intersection of CR 58 and CR 51. More specifically, the Study Area is located in eastern half of Section 7, Township 5 North, Range 64 West in Weld County, Colorado (Latitude 40.242690 North, Longitude 104350559 West). Figure 1 provides a general vicinity ma ; Figure 2 shows the Study Area location on a U.S. Geological Survey (USGS) 7.5 Minute Series Topographic Map. Fi re 1.

The Study Area is bound by agricultural land to the north and west, CR 51 to the east and CR 58 to the south. The Study Area slopes to the northeast on the western side of the Study Area and the remainder of the area is largely flat. The Study Area includes two active irrigation ditches (North Branch of Plumb Ditch, and South Branch of Plumb Ditch), a vegetated wetland swale, a hydrologically isolated wetland, and adjacent upland areas. The majority of the Study Area is currently utilized as pasture land and also includes a home, several out buildings, an il well and several access roads. They Weld County Soil Survey depicts three soil types within the study area: (1) Altvan loam, 0 to 1 p rcent slopes; (3) Aquolls and Aquents, gravelly substratum; and (68) Ustic Torriorthents (U DA-NRCS 2007a, USDA-SCS 1980). Figure 3 shows the soils mapped within the study are. Two of the three soils found within the Study Area (the Altvan loam, and the Aquolls and Aquents) are classified as hydric (NRCS 2007b). The Altvan loam occurs on terraces of alluvium deposited by major rives and occupies approximately 3.68 acres within the study area. The Aqoolls and Aquents occur on bottom lands and floodplains occupying approximately 74.67 acr s within the Study Area. The non-hydric Ustic Torriorthents occur on moderately steep to ce breaks occupying approximately 20.08 acres within the Study Area. 3 109 • t • Ke sey Gravel Wetland Delineation Report Figure 3.

Three general environmental parameters define a wetland. These parameters consist of the presence of hydrophytic vegetation, hydric soils, and wetland hydrology. Areas that do not meet any one of the wetland parameters (hydrophytic vegetation, hydric soils and/or wetland hydrology) were classified as a non -wetland and mapped as such. In addition, waters of the U.S. are 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". Waters of the U.S. 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". These definitions are the basis of this delineation. ERC conducted a wetland delineation to identify and document the presence and extent of wetlands and waters of the U.S. within the Study Area. The delineation was completed using the routine (on -site) methodology and criteria specified in the 1987 Corps of Engineers Wetlands Delineation Manual and subsequent guidance (1987 Manual) (Environmental Laboratory 1987, U.S. Army Corps of Engineers (USACE) 1991, USACE 1992). References to the 1987 Manual and to Environmental Laboratory 1987 in this report are intended to include all subsequent guidance to the Manual. These methods require that evidence of three parameters (a dominance of hydrophytic vegetation, hydric soils, and wetland hydrology) be simultaneously present for a wetland determination. Routine wetland determination forms were completed for each data plot identifying information on vegetation, soils, and hydrology (Appendix C). Based on the field observations, a wetland determination was made, the limits of plant community types delineated, and a wetland/upland boundary field flagged. Each wetland boundary determination point was identified in the field with a pink pin flag. Upon completion of the delineation and GPS mapping, the wetland flags were removed at the request of the land owner. Each wetland determination point was recorded using a Trimble Global Positioning System (GPS) GeoXH. Where no wetlands were present, potential waters of the U.S. were delineated using either the OHWM of the channel, or the channel centerline. Post processing differential correction provided mapping accuracy (horizontal) of +/- 2.0 feet. Wetland areas were plotted using ArcMap GIS (Version 9.2) and overlain on a 2006 orthorectified aerial photograph which was obtained from the U.S. Department of Agriculture -Farm Service Agency (USDA-FSA). The enclosed wetland delineation map (Appendix B) dated July 10, 2008, represents the wetland areas and irrigation ditches identified by ERC within the Study Area. 5.0 Summary of Findings Irrigation Ditches Two active irrigation ditches are located within the Study Area: the North Branch of Plumb Ditch and the South Branch of Plumb Ditch. Plumb Ditch (formerly known as Highland Ditch), originates from the South Platte River and flows for approximately 2.3 miles prior to entering the Study Area on the west side. The Highland Ditch was decreed in the District Court of Arapahoe County on April 28, 1883 with an appropriation date of October I, 1871 for 24.4 cubic feet per 5 111 Kersey Gravel Wetland Delineation Report Ecological Resource Consultants, Inc. second (cfs) from the South Platte River (District Court, Water Division 2007). Water flow is controlled by a headgate on the south bank of the South Platte River (Section 13, Township 5 North, Range 65 West). The main channel of Plumb Ditch branches in several locations in order to provide irrigation water to several farms. Ultimately, the main channel of Plumb Ditch flows back in to the South Platte River approximately 1.3 miles east of the Study Area. North Branch of Plumb Ditch (1,714 feet / 0.28 acres) The North Branch of Plumb Ditch flows east along the northern boundary of the Study Area (Appendix B). The ditch is approximately 7 feet wide and 1,714 feet long within the Study Area and exhibits a highly channelized, linear shape. The banks of the ditch are steep and sparsely vegetated, likely due to the high volume of water that is seasonally released through the ditch and the regular maintenance of the ditch. At the time of the site visit, the ditch contained flowing water. The North Branch of Plumb Ditch is bordered to the north and south by dirt roads. Irrigated farmland is found adjacent to both roads. Both the roads and the farmland are separated by a berm along the ditch. South Branch of Plumb Ditch (1,718 feet / 0.40 acres) The South Branch of Plumb Ditch flows east through the northern third of the Study Area, approximately 500 feet south of the North Branch (Appendix B). The ditch is approximately 10 feet wide and 1,718 feet long within the Study Area, and has steep, moderately vegetated banks that are highly channelized to carry large amounts of seasonal irrigation water. At the time of the site visit, the ditch contained flowing water. A dirt road borders the ditch to the north, and irrigated farmland is located to the south of the ditch. Both the road and the farmland to the north are separated by a berm along the ditch. Several building structures are located on the north side of the ditch, near the western property boundary. The North and South Branches of Plumb Ditch exhibit a distinct linear shape, and are clearly manmade. Excavated into uplands and lined by steep banks, the ditches sit higher in the landscape than the adjacent dirt roads and structures and therefore do not drain other wetlands. The source of hydrology for the ditches is solely irrigation water and regulated by a headgate at the South Platte River which releases water seasonally. Therefore the ditches do not carry a permanent (or relatively permanent) flow of water. Diverted irrigation water flowing through the ditches does eventually drain into the South the South Platte River, a Traditional Navigable Water (TNW). The ditches do not appear to intercept or carry any other tributary flow. A USGS topographic map showing Plumb Ditch's course from beginning to end is included in Figure 4. Wetlands ERC delineated two specific areas within the Study Area that exhibited wetland characteristics. A description of the wetland characteristics is provided as follows. Wetland A (4.79 acres) Wetland A is classified as a palustrine emergent wetland under the Cowardin et al. 1979 classification system (Appendix A, Photos 1 and 2). The wetland is bordered by the North Branch of Plumb Ditch to the north, and by the South Branch to the south. The wetland appears to receive seepage from the adjacent irrigation ditches during periods of active irrigation. The wetland extends the length of the Study Area (west to east), adjacent to the northern Study Area boundary, and is bordered by CR 51 on the east side. Wetland A is a depressional wetland that sits lower on the landscape than the Plumb Ditches.

No culverts were noted on the east end of the wetland and no culverts or wetland complexes were noted immediately east of CR 51. At the time of the site visit, Wetland A did not exhibit any indicators of hydrology. For the wetland determination, hydrology was assumed because the wetland is highly influenced by the irrigation ditches and will likely demonstrate signs of hydrology (such as drainage patterns or saturation) later in the growing season. The wetland appears to be hydrologically isolated. Dominant vegetation within Wetland A includes three -square, curly dock and bulrush species; all of which are FACW or OBL species. Soil color within the wetland consists of a black (10YR 3/1) to very dark gray (10YR 3/2) in the upper 16 inches of the soil profile. A low quantity of mottling was observed within the test pits. Soil mottling colors were on the order of a reddish brown (5YR 3/4). A list of dominant vegetation identified within the wetland is provided in Table 1. Table I.

The wetland is an approximately ten foot wide swale which begins in the central portion of the Study Area, near the out buildings. The swale flows southeast across the Study Area and through a culvert under CR 51, where it flows into Plumb Ditch, which eventually connects to the South Platte River approximately 1.3 miles east of the Study Area. The swale appears to be manmade due to the linear and uniform shape observed. The banks and bottom of the swale are vegetated and areas of stagnant water were noted along the length of the swale. The area is actively used as part of a grazing pasture. Wetland B is likely influenced by both ground water and irrigation water. At the time of the site visit, hydrologic indicators included drainage patterns in the wetland and saturation within the upper 12 inches of soil throughout the wetland. The east side of Wetland B was inundated, draining through culvert under CR 51 into Plumb Ditch. At times of heavy irrigation, Wetland B likely contains large amounts of flowing water, from the culvert on the west side of the Study Area, as indicated by the wetland's high banks. Dominant vegetation within Wetland B consists of three -square, bulrush species, cattail and salt grass. Soil color within the wetland consists of a black (I0YR 3/1) to very dark gray (10YR 3/2) in the upper 16 inches of the soil profile. No mottling was observed.

FAC = facultative vegetation -equally occurs in non -wetlands as wetlands General Adiacent Uplands Uplands within the Study Area are primarily disturbed, resulting from agricultural activities and animal grazing. A dirt access road exists along a ridge on the west side of the Study Area, generally defining the Study Area boundary. Two other access roads exist to provide access to the active agricultural ditches on the north side of the Study Area and the oil well in the central portion. Uplands within the Study Area are primarily vegetated by western wheatgrass, salt grass, sweet clover and kochia. These areas are generally characterized by having dry soils. Additionally, a dominance of wetland vegetation was not present within areas identified as upland.

Two irrigation ditches, the North Branch and South Branch of Plumb Ditch, were identified within the Study Area. ERC also delineated two areas (Wetland A and Wetland B) exhibiting the characteristics of a wetland. A summary of the areas investigated during the site visit is provided as follows. Irrigation Ditches The North Branch of Plumb Ditch flows east along the northern boundary of the Study Area. The South Branch of Plumb Ditch flows east through the northern third of the Study Area, approximately 500 feet south of the North Branch. Both branches are manmade, active irrigation ditches that are regulated to release irrigation water seasonally through a headgate located on the South Platte River. The ditches are excavated wholly in and draining only uplands and do not carry a permanent or relatively permanent flow of naturally occurring water. The ditches do not intercept or convey other tributary flows and would cease to exist without the dedication of irrigation water rights. Wetlands Wetland A is located in the northern third of the Study Area. The wetland is depressional and hydrologically isolated from the North Branch and South Branch of Plumb Ditch. The wetland is immediately bordered to the north and south by dirt access roads which sit several feet higher topographically than the wetland. There is no observed connection to a wetland on the east side of CR 51. The wetland appears to be completely dependent on seepage from the nearby irrigation ditches. The area meets all of the characteristics defining a wetland. 9 115 Kersey Gravel Wetland Delineation Report Ecological Resource Consultants, Inc. Wetland B is a manmade swale historically dug from uplands. The swale begins in the central western portion of the Study Area and flows offsite where it connects to Plumb Ditch and eventually drains into to the South Platte River, approximately 1.3 miles east of the Study Area. The swale meets all of the characteristics defining a wetland. eatu res Name Classification Size* Description Hydrological Connection WETLANDS Wetland A Palustrine Emergent 4.79 ac Depressional wetland, hydrologically isolated.

Plumb Ditch flows from a headgate on the South Platte River (Section 13, Township 5 North, Range 65 West) for 2.3 miles before entering the Study Area on the west side. The main channel of Plumb Ditch flows back in to the South Platte River approximately 1.3 miles east of the Study Area. South Branch Plumb Ditch Irrigation Ditch 1,718 ft / 0.40 ac Manmade ditch, excavated in uplands. Total acreage of identified wetlands and ditches within the Study Area = 7.0 ac Note: `Size offeature measured within Study Area. Acres = ac Linear ft = ft The attached wetland delineation map dated July 10, 2008, represents the delineated wetlands and irrigation ditches within the Study Area. These areas may be regulated by the USACE under Section 404 of the Clean Water Act. The placement of fill material or any general land disturbance within mapped waters of the U.S./Jurisdictional wetlands will require prior authorization from the USACE. In accordance with the November 13, 1986 Federal Register (Page 41217) Guidance and May 30, 2007 Rapanos Guidance (page 36), the Corps of Engineers generally does not consider non -tidal drainages and irrigation ditches excavated on dry land to be waters of the U.S., except on a case - by -case basis. In this case, the North and South Branches of Plumb Ditch are manmade ditches excavated wholly in and draining only uplands. Flow of water is regulated by a headgate, and is therefore not considered permanent. The USACE will need to make a jurisdictional determination of this site feature. Wetland A is a hydrologically isolated, irrigation influenced wetland. Under current USACE guidelines, wetlands which are not adjacent to or abutting TN Ws or waters which flow to TN Ws are typically considered non jurisdictional (USEPA & USACE 2007). Wetland A sits lower in the landscape than the surrounding ditches and does not contribute a surface hydrologic 10 116 Kersey Gravel Wetland Delineation Report Ecological Resource Consultants, Inc. connection or significant nexus to TNWs. The USACE will need to make a jurisdictional determination of this site feature. Wetland B is manmade and influenced by both groundwater and irrigation water. The wetland conveys relatively permanent water directly to the South Platte River (a TNW) and therefore is likely considered jurisdictional per current regulatory guidance (USEPA & USACE 2007). In closing, ERC has identified 7.0 acres of water features which include irrigation ditches and wetlands within the 96 acre study area. Current regulatory guidance does not provide a definitive interpretation of the jurisdictional status of the two irrigation ditches and Wetland B. The USACE must review the jurisdictional status of these features and make a site specific determination. Jurisdictional status of Wetland A is more clear under current guidance, and is likely jurisdictional. ERC is requesting a jurisdictional determination of this wetland delineation report from the USACE. Jurisdictional wetlands and waters of the U.S. are regulated by the USACE under Section 404 of the Clean Water Act. The placement of fill material within jurisdictional areas is prohibited with out USACE authorization. ERC recommends that no disturbance occurs within the identified wetlands until a jurisdictional determination is made by the USACE.

(ERC) previously completed the below listed environmental stud es for a parcel of land, referred to as the Kersey Gravel Site, located on approximately 96- acreS in the eastern half of Section 7, Township 5 North, Range 64 West in Weld County, Colorado. Envjronmental Studies completed by ERC include: } Wetland Delineation Report for the Kersey Gravel Site Weld County Colorado, July 10, 2008, Ir Screening Report of Threatened, Endangered and Species of Concern for the Kersey Gravel Site, Weld County, CO May 9, 2009, O Burrowing Owl Clearance Survey for the Kersey Gravel Site, Weld County, Colorado July 7, 2008, and ♦ Wildlife Memo, Kersey Gravel Site, September 29, 2008. Thee studies specifically addressed environmental condition for a study area defined by LOT B. At t e request of J&T Consulting, ERC provides this letter to include LOT A as part of the overall stud area, which was previous considered an outlot. Although LOT B was the defined study area for he environmental studies, LOT A was incidentally evaluated due to its proximity and con ectivity to LOT B. Refer to the attached Recorded Exemption Plat for specific boundary lay t LO A is an approximately 11.86 -acre parcel situated in the center of LOT B along the western pro erty line of LOT B. LOT A is a relatively flat, active pasture land towards the eastern half. A sma 1 residential house, several barns and farm structures exist along the western half Along wes em property line of LOT A, topography becomes much steeper. ER conducted a field visit of LOT A on November 6, 2008. Weather was cold and windy, veg tation was entering dormancy, soils where thawed and the ground surface was visible. ERC tray rsed LOT A, to determine any conditions that may indicate the presences of wetlands, thre tend, endangered and species of concern or wildlife concerns as address in the previously co pleted environmental studies. The following provides an overview of findings for LOT A: 133 • Wetl : nds The chysical characteristics of LOT A are consistent with the findings described as Uplands in the Wetl d Delineation Report. The entire LOT is comprised of dry disturbed lands resulting from agric ltural activities and grazing. Dominant vegetation consists of wheatgrass (Pascopyron smit ii), salt grass (Distictalis spicata), sweet clover (Trifolium sp.) and kochia (Kochia scopari), all considered non -wetland plants. Hydric soil and wetland hydrology indicators were not observed. In summary, LOT A is considered disturbed upland habitat and does not contain any wetland habitat. Threatened, Endangered and Species of Concern The physical characteristics of LOT A are consistent with the findings Summary provided as part of tl$e LOT B Screening Report of Threatened, Endangered and Species of Concern. Findings addr?ssed in the Summary should be considered applicable to LOT A. However, because no prairie dog colonies are present in LOT A, the presences of burrowing owls is not a concern. Wil life The physical characteristics of LOT A are consistent with the findings presented in the Wildlife Memo for LOT B. Findings addressed in the Wildlife Memo should be considered applicable to LOt A. • PHOTO 1. View across center of upland pasture meadow from the western side of LOT B towards the east (11-6-08).

The climate data collected from 1967 through 2007 indicates the average total annual precipitation at the site to be approximately 14.04 inches per year and annual mean temperature to be approximately 50.5 degrees Fahrenheit. 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.

Journey Ventures, LW. Journey Ventures Pit DRMS 112 Permit Application 136 EXHIBIT L Reclamation Cost A phas d and cumulative bonding approach is proposed for the Journey Ventures Pit operation. The fin ncial warranty required for each phase is the warranty required to completely reclaim that ph se. 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 operatdr 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 lover 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 Divisiob. 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 fdllowing table summarizes the financial warranty required for each phase, and the cumulative financial warranty that will be provided during any given phase. ' JaT Consulting. Inc.

More specifically the property is located in the Southeast'/, and the Southeast 1/4 of the Northeast 1/4 of Section 7, Township 5 North, Range 64 West, Sixth P.M. in Weld County, Colorado. The property is bounded by private property on the north, and west, Weld County Road 51 on the east, and private property and Weld County Road 58 on the south. United States Highway 34 is approximately one mile south of the subject property. 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 setback of 200 feet 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 prior geotechnical gravel investigations by Terracon Consultants (TC) and J.A. Cesare & Associates (JAC), and methodology used in the analysis of the mining slopes and their estimated affects on the adjacent man-made structures. Recommendations regarding acceptable setbacks from man-made structures have also been included. II - OVERVIEW JV proposes that the property will be mined in phases until the entire site is mined. The future use for this property is expected to be a lined water storage reservoir. The lining will be done using a perimeter slurry wall that is keyed into the underlying bedrock. The mined and reclaimed slopes will be the same, with a 3h:1v embankment down to an elevation 10 feet below the expected reservoir water surface, and 2h:1v embankment from that point down to the reservoir/pit bottom. Portions of the south and west mining/reclaimed slopes will contain a horizontal bench located 3 feet above the expected water surface to facilitate the construction of the slurry wall. The reservoir will cover an estimated 57 surface acres when full. Actual surface area will depend on the final configuration of the reservoir after reclamation is complete. III - GEOTECHNICAL DATA Geotechnical gravel investigations for the property have been performed by TC and JAC. J&T Consulting, Inc. (JT) estimated soil strength parameters based on the information from the TC and JAC reports, and other stability analyses that have been performed on gravel mining operations located in similar soils. Table 1 represents a summary of the soil strength parameters that were used in this stability analysis.

XSTABL was designed to analyze the slope stability of earth embankments subjected to several critical situatio s that may occur during the life of the embankment. Static and pseudo -static conditions were analyzed in each case. Pseudo -static peak acceleration factors were taken from USGS information for the western United States. The 2% probability of exceedance in 50 years (the most conservative) was used. Surface loads equivalent to an HS 20 highway load were applied adjacent to each area, when applicable, to simulate heavy equipment loading that could be present at that location. For this project, seven cases were identified as critical during the mining operation: Case 1 — Existing Weld County Road 51, existing overhead electric, gas, water, and telephone lines to the east. The mining operation is adjacent to numerous man made structures in this area. The proposed setback for mining is 55 feet from the proposed permit boundary, and 25 feet from the existing County Road 51 right-of-way. The mining depth was assumed to be 55 feet in this area based on bore log information in the geotechnical reports. The mining side slopes in this location will be 3h:1v to 10 feet below the expected water surface, and 2h:1v from that point down to the pit bottom. Case 2 — Existing fence, Weld County Road 58 to the south. The mining operation is adjacent to an existing fence and Weld County Road 58 in this area. The proposed setback for mining is 25 feet from the permit boundary/fence, and 60 feet from the Weld County Road 58 right-of-way. The mining depth was assumed to be 79 feet in this area based on bore log information in the geotechnical reports. The mining side slopes in this location will be 3h:1v to 10 feet below the expected water surface, and 2h:1v from that point down to the pit bottom. A horizontal bench will be located in the slope 3 feet above the expected water surface to facilitate the construction of the slurry wall. Case 3 — Existing oil/gas well to the southwest. The mining operation is adjacent to an existing oil/gas well in this area. The proposed setback for mining is 150 feet from the oil/gas well. The mining depth was assumed to be 64 feet in this area based on bore log information in the geotechnical reports. The mining side slopes in this location will be 3h:1v to 10 feet below the expected water surface, and 2h:1v from that point down to the pit bottom. • _ Li _ Case 4 — Existing oil/gas well to the southwest. The mining operation is adjacent to an existing oil/gas well in this area. The proposed setback for mining is 150 feet from the oil/gas well. The mining depth was assumed to be 78 feet in this area based on bore log information in the geotechnical reports. The mining side slopes in this location will be 3h:1v to 10 feet below the expected water surface, and 2h:1v from that point down to the pit bottom. Case 5 — Existing access easement to the west. The mining operation is adjacent to an existing access easement in this area. The proposed setback for mining is 25 feet from the access easement, and 55 feet to the property/permit boundary. The mining depth was assumed to be 76 feet in this area based on bore log information in the Journey Ventures, LLC - Kersey Gravel Pit Slope Stability Analysis Page 2 • • • geotechnical reports. The mining side slopes in this location will be 3h:1v to 10 feet below the expected water surface, and 2h:1v from that point down to the pit bottom. A horizontal bench will be located in the slope 3 feet above the expected water surface to facilitate the construction of the slurry wall. Case 6 — Existing oil/gas wells and tank battery to the southeast. The mining operation is adjacent to existing oil/gas wells and an existing tank battery in this area. The proposed setback for mining is 150 feet from the existing oil/gas wells and existing tank battery. The mining depth was assumed to be 80 feet in this area. Bore log information in the geotechnical reports shows the depth of the gravel to be greater than 80 feet in this area, however mining will terminate at a depth of 80 feet to maintain the stability of the mining slope. The mining side slopes in this location will be 3h:1v to 10 feet below the expected water surface, and 2h:1v from that point down to the pit bottom. Case 7 — Existing Plumb Ditch, south branch, to the north. The mining operation is adjacent to an existing ditch in this area. The proposed setback for mining is 25 feet from the proposed permit boundary/existing ditch bank. The mining depth was assumed to be 80 feet in this area. Bore log information in the geotechnical reports shows the depth of the gravel to be greater than 80 feet in this area, however mining will terminate at a depth of 80 feet to maintain the stability of the mining slope. The mining side slopes in this location will be 3h:1v to 10 feet below the expected water surface, and 2h:1v from that point down to the pit bottom. The cross -sections located in Appendix B show the proposed mining slope geometry, estimated phreatic surface, location of the man made structures relative to the mining slope, and location of the most critical slope failure surface for each case. V - 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. 2,000 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. S Journey Ventures, LW - Kersey Gravel Pit Slope Stability Analysis Page 3 • • • VI - SLOPE STABILITY RESULTS The SEO requires minimum factor of safety of 1.25 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 factors of safety for this project and should be considered as highly conservative for evaluating alluvial mining high walls. The calculated factors of safety are within the design criteria specified for this project and can be considered indicators of the high wall performance under the various conditions. The results of the static condition and pseudo -static condition slope stability analyses are presented in Table 2 and Table 3.

A visual inspection of the excavated high walls should be done on a weekly basis for the first 6 months 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 high walls is expected on any mine site. The intent of this inspection is to locate potential major slope failures that could 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 within the first 6 months, then the inspection period could be reduced to once per month or after every major precipitation event.

The purpose of these services is to provide information and recommendations relative to: • subsurface soil and bedrock conditions. • groundwater conditions. • feasibility of site for use as a sand and/or gravel mine. The recommendations contained in this report are based upon the results of field and laboratory testing, engineering analyses, our experience with similar soil conditions, and our understanding of the proposed project. PROJECT INFORMATION Based on information provided by the client, the approximately 100 -acre site is being considered for development as a sand and gravel mining operation pit. SITE EXPLORATION PROCEDURES The scope of the services performed for this project included site reconnaissance by a geotechnical engineer, a subsurface exploration program, laboratory testing and reporting. Field Exploration: A total of 4 test borings were drilled on February 21, 2008 to depths of about 50 feet below existing site grade at the approximate locations shown on the Boring Location Diagram, Figure 1. The borings were advanced with a truck -mounted air percussion drilling rig, utilizing 6 -inch inside diameter flight auger. The borings were located in the field with assistance from the client. The accuracy of boring locations should only be assumed to the level implied by the methods used. • Geotechnical Engineering Report Sand and Gravel Study Terracon Project No. 21085006 Terracon Lithologic logs of each boring were recorded by the geotechnical engineer during the drilling operations. At selected intervals, samples of the subsurface materials were obtained by collecting bulk samples of material through the cutting funnel. Groundwater measurements were made in each boring at the time of site exploration. All borings were filled after drilling operations due to safety considerations for livestock on site. Minor boring settlement should be expected, some maintenance should be anticipated. Laboratory Testing: Samples retrieved during the field exploration were returned to the laboratory for observation by the project geotechnical engineer, and were classified in general accordance with the Unified Soil Classification System described in Appendix C. At that time, an applicable laboratory -testing program was formulated to determine physical properties of the subsurface materials. Following the completion of the laboratory testing, the field descriptions were confirmed or modified as necessary, and Logs of Borings were prepared. These logs are presented in Appendix A. Laboratory test results are presented in Appendix B. Laboratory tests were performed in general accordance with the applicable local or other accepted standards. SITE CONDITIONS The approximately 100 -acre site is currently used primarily for pasture and agricultural purposes. The site was bounded on the north by the Cache La Poudre River, on the east by Weld County Road 51, on the south by Weld County Road 58, and on the west by hilly terrain with sparse residential/agricultural development. The ground surface was generally flat to gently rolling. Vegetation consisted of grasses and native weed growth. Geology: Surficial geologic conditions at the site, as mapped by the U.S. Geological Survey (USGS) (1Tweeto, 1979), consist of Post Piney Creek Alluvium of Upper Holocene Age. This material generally consists of dark gray humic, sandy to gravelly alluvium. These materials, as mapped in this area, are generally on the order of about 20 feet in thickness. Economic Mineral Potential: Mapping performed by the USGS (2Schwochow, Shroba, and Wicklein, 1974) indicates that the site lies in an area of flood -plain and valley fill deposits along 2Tweeto, Ogden., 1979, Geologic Map of Colorado, United States Geological Survey, Map l -855-G. 2Schwochow, S.D., Shroba, R.R, and Wicklein, P.C., 1974, Sand, Gravel, and Quarry Aggregate Resources of the Colorado Front Range Counties, Colorado Geological Survey, Special Publication 5-A, Plate 1. Geotechnical Engineering Report Sand and Gravel Study Terracon Project No. 21085006 Terracon present stream courses with stream deposits consisting of coarse and fine aggregate resources. This is consistent with the materials encountered in our borings. Mapping performed by the USGS (3Trimble and Fitch, 1974) adjacent to the project site indicates that the site likely contains a gravel deposit underlying flood plains and terraces. The materials are described as pebbles and clasts generally well rounded, unweathered, and contain little deleterious "lime" (CaCO3). Clasts are composed chiefly of quartzite, granite, gneiss, and pegmatite. The material contains few or no reactive constituents and is a source of quality gravel for concrete and aggregate and road metal. Thicknesses of the deposits mapped close to the area range from approximately 16 to 28 feet in thickness. Based on the materials encountered in our borings, it is likely that commercially extractable mineral deposits are located on the project site. Due to the relatively flat nature of the site, geologic hazards at the site are anticipated to be low. Seismic activity in the area is anticipated to be low, and the property should be relatively stable from a structural standpoint. With proper site grading around the proposed mine, erosional problems at the site should be reduced. Soil Conditions: As presented on the Logs of Boring, surface soils consisted of about 6 inches of topsoil and about 3 feet of clayey sand. The overburden materials underlying the surface soils and extending to depths of 50 to 57 feet consisted of cobbles, gravel, and sand with varying amounts of silt and clay. Field and Laboratory Test Results: The classifications included in Appendix B indicate the overburden materials generally classify as gravels and sands with varying amounts of silt. These classifications were performed on the bulk samples which were returned in the cutting funnel during drilling activities. Gravels encountered ranged from 34 -inch diameter to 4 -inch diameter. Percentages of size distribution are presented in the laboratory test results in Appendix B. Groundwater Conditions: Groundwater was encountered at depths of about 4 to 8 feet below existing site grade in the test borings at the time of field exploration. These observations represent groundwater conditions at the time of the field exploration, and may not be indicative Trimble, Donald E., and Fitch, Harold R-, 1974.

Groundwater levels can be expected to fluctuate with varying seasonal and weather conditions. Based upon review of U.S. Geological Survey Maps, (°Hillier, et al, 1979), regional groundwater beneath the project area is expected to be encountered in unconsolidated alluvial deposits on the site at depths ranging from 5 to 10 feet below present ground surface. Sand/Gravel Mining Considerations: Based upon the materials encountered during the geotechnical exploration of the site andthe results of the laboratory testing, the site appears to be feasible for the purpose of mining significant quantities of gravel sized or larger aggregate. The depth of these materials ranges from approximately 3 to 57 feet below existing site grade. The depth of groundwater encountered indicates that the extraction of the majority of this material will require dewatering operations. Methods for dewatering could consist of installing isolated well points or placing a slurry wall system around the proposed mining area. We recommend that the owners consult with an experienced sand/gravel mining company to further asses the economic and physical viability of using the site for mining. GENERAL COMMENTS This report should not be relied upon for final design, and should only be used for planning and budget purposes. The analysis and recommendations presented in this report are based upon the data obtained from the borings performed at the indicated locations and from other information discussed in this report. This report does not reflect variations that may occur between borings, across the site, or due to the modifying effects of weather. The nature and extent of such variations may not become evident until during or after construction.

Groundwater levels at other times and other locations across the she could vary. In pervious sells, the indicated levels may reflect the location of groundwater. In low permeability soils, the accurate determination of groundwater levels may not be possible with only short-term observations. DESCRIPTIVE SOIL CLASSIFICATION: Soil classification Is based on the Unified Classification System. Coarse Grained Soils have more than 50% of their dry weight retained on a #200 sieve; their principal desaiptora are: boulders, cobbles, gravel or sand. Fine Grained Soils have less than 50% of their dry weight retained on a #200 sieve; they are principally described as clays if they are plastic, and silts If they are slightly plastic or non-plestla Major constituents may be added as modifiers and minor constituents may be added according to the relative proportions based on grain size. In addition to gradation, coarse -grained soils are defined on the basis of their in -place relative density and fine-grained sob on the basis of their consistency.
