Until that time the Mineral Reserve Areas will be used to support both wet and dry plant operations and stockpiling of processed materials. An existing basin (created by previous agricultural activity) within the 10.00± acre Mineral Reserve Area ( 1 ) will be utilized as a wash pond to support all on-site plant/processing activities. A portable scalehouse/office and/or concrete and/or asphalt batch plant and/or recycling facilities may also be located in the Mineral Reserve Areas. The actual location, extent, and facilities will be detailed and identified by location an extent in a later technical revision to the original approved permit. No on-site storage of fuels is planned as portable fuel (trucks) will service all heavy and correlated operational equipment. An electrical line serving operations is not shown on included maps as it is established by the operator, temporary, and subject to relocation in cooperation with United Power Company. All other power and related overhead or buried lines are outside of the influence of extraction activity, or will otherwise be relocated in cooperation with their owners or other responsible parties where they conflict within the interior of planned extraction. Buried oil and gas lines are estimated, and extraction and offset of operations are approximate and will be determined in the field in cooperation with the Utility Notification Center of Colorado. It should be noted that a homestead and yard with outbuildings occupies 1 .50± acres and acts to divide the north central permit boundary. The access road leading Varra Companies, Inc. OMI,R 112 Permit Application 2 Parcel 122 — Resource Development Project 1 July 2015 Exhibit D- Mining Plan to the homestead has an active easement for operations which will be used as secondary access for light vehicles and equipment. *Immediately south of the residential yard, existing facilities prevent the area from being used other than as a storage or parking area for vehicles, equipment (including heavy equipment), supplies, or other operational support purposes. This location is fully disturbed by prior agricultural and landowner purposes. This may also include the placement or construction of storage structures and materials. The primary access for heavy equipment, service vehicles, haul trucks and related traffic is located along an established access road that traverses the east line of the permit boundary. Both access roads intersect Weld County Road 28 that flanks the northern extent of the permit boundary. A grader and water truck maintain access within the permit area as necessary throughout operations. The aggregate deposit varies in composition, depth and extent. Generally, depths are shallower toward the southeast, trending deeper toward the northwest, and are consistent with the gradient flow of groundwater which appears to be at stasis near elevation 4795 feet. Tract B (East Basin) falls from 15-45+ feet and Tract A (West Basin) from 35-60+ feet from the surface to the underlying unconsolidated bottom. Unconsolidated suitably derived on-site material may be used for diverse purposes, including commercial products, or the re-grading of the extracted basin. These same materials may also be used to line the completed basins (refer to Exhibit G — Water Resources, Part 6 for details on how completed basins will be lined, if lined). Whether lined or unlined, the basins form the primary end use as developed water resource, and will be utilized accordingly. To facilitate dry extraction of overburden and aggregate, groundwater will be discharged from the areas of active extraction at one or more of the three designated discharge locations identified on Exhibit C-2 : Extraction Plan Map. Discharge of waters will be conducted under an approved Colorado Dept. of Health discharge permit, as indicated under Exhibit M — Other Permits. The FEMA designated flood plain was severed in 1911 with the construction of the Union Pacific railroad bed located approximately 1 mile to the west. While found within and along the terminus of the upper terrace of the historic floodplain of St. Vrain Creek, operations will not impact the active FEMA designated floodplain. The general direction of extraction activities over the Tracts is from north to south, as shown on Exhibit C-2 — Extraction Plan Map. No extraction will occur within 125 feet of a residential structure, or ten feet of any other structure, property Varra Companies, Inc. OMLR 112 Permit Application 3 Parcel 122 — Resource Development Project 1 July 2015 Exhibit D- Mining Plan boundary, right-of-way, or casement without written agreement with the owner of said structure. These setbacks supersede any representation of the extraction limits shown on Exhibit C-2 : Extraction Plan Map. Extraction activities will be limited to within 25 .0± feet of well heads and facilities, and those same wellheads will be backfilled to create a 100± foot radius around the well head for future oil and gas activities at that well head. The fill around well heads will occur concurrently with extraction around the well head and facilities, to the extent practical. At all times, safety will take precedent and over-ride as necessary any element of the permit to assure protection of life and property and compliance with federal safety regulations (MSHA). Changes resulting from a safety consideration that require a modification of the approved permit will be made after the fact respective of amendment or technical revision provisions of the Office of Mined Land Reclamation (OMLR). Initially, heavy equipment (typically, scrapers, dozers, or excavators operating alone or in combination) will extract soil, placing it along the basin perimeter in the construction of up to a five (5 .0±) foot high visual berm. The berm may vary in height and width. Outslopes of the berm will be 3H: 1V or flatter to aid establishment of grasses and utilizing the approved seed mixture. Where necessary to aid in access along the perimeter of the pit or completed reservoir, the berms may be increased in width to better facilitate the access of vehicles or heavy equipment. The height and width of the berm will be field fit at the time of placement and will not go beyond permit limits. While the berm width will vary, they will fit within the ten ( 10.0±) foot buffer between the permit boundary and any planned extraction; and where wider, will extend into the basin area conforming to 3H: 1V minimum outslopes. To the extent possible, the height of berms will near five (5 .0±) feet along the perimeter where a residential structure is within 125 .0± feet from active extraction operations. Soils volumes extracted in excess of that needed for reclamation may be temporarily stockpiled as part of the berms, elsewhere on-site, or conveyed to nearby Kurtz or Heintzelman Projects, until sold as product. It should be understood that there is no ` overburden' at this location, as all materials are viable product or useful component to the reclamation of affected lands and establishment of the desired end uses. Subsequent to soil salvage, extraction of aggregate will commence. Extraction utilizes, but is not limited to, diverse heavy equipment; including, scrapers, excavators, dozers, backhoes, and related heavy equipment. The raw material will be transported by heavy equipment or haul trucks to on-site plant facilities. Varra Companies, Inc. OMLR. 112 Permit Application 4 Parcel 122 — Resource Development Project 1 July 2015 Exhibit D- Mining Plan Any method that accelerates the operation timetable will be utilized, depending upon market conditions and the capacities of the operator. To this end, an existing conveyor system is established in the northeast corner of Tract A. Extracted resource may be conveyed to or from other Varra Companies, Inc. off-site plant facilities. One conveyor system and route is already established on the northwest corner of the permit area and will convey materials to or from the Kurtz operation to the North. A second conveyor route may be established (subsequent to an approved OMI,R technical revision) along the west permit boundary to facilitate movement of materials to and from the adjacent Heintzelman operation. Processed and unprocessed or otherwise Colorado Department of Health compliant inert materials may originate from different sources and locations for import and utilization for our on-site processing, commercial, or reclamation interests; either as product in its unaltered state, or as otherwise processed, recycled, or repurposed from on-site processing and operations. All inert materials may arrive via conveyor or overland haulage. While initial operations will commence on the north boundary of Tract A, both Tracts A and B may be extracted concurrently. All extraction will proceed in a manner to minimize visual and audible impacts to adjacent lands and properties. In Tracts A or B, extraction will commence to facilitate removal of material from a nearby residence and County Road 28 to better distance those locations from operations over time; and to gain time to vacate or relocate any utilities, oil and gas lines, or other structures from the interior of the tracts as needed, and in cooperation with the owners or other responsible parties. Extraction activities will remove aggregate to a weighted average depth of 39.0± feet from the surface. Anomalous depths greater than 50.0± feet may occur. While extracted slopes may be temporarily 1 .25H: 1 V, all final basin (reservoir) slopes will be established concurrently with extraction and will conform to Rule 3 . 1 .5 (7), or flatter (refer to Exhibit S — Stability Analysis). Initially a 1600+ foot extraction front will advance along its east-west orientation from the northern extraction limit toward the southern permit boundary. The advancing front will be comprised of side slopes nearly 400 linear feet at 1 .25H: 1 V along each side of an 800 foot advancing wall. Concurrent reclamation will trail this front by approximately 400 foot increments. This front is approximate for all active Tracts. As the basin floor and perimeter boundary is reached, final grading may commence once a minimum area of approximately four acres (or a distance of Varra Companies, Inc. OMLR. 112 Permit Application 5 Parcel 122 — Resource Development Project 1 July 2015 Exhibit D- Mining Plan 400 linear feet square) is attained. Finished slopes will be established along the basin perimeter utilizing fill material taken from the basin bottom. If Tract B opens concurrently at some point in time with Tract A, as per Exhibit L — Warranty Costs, additional warranty may be applied to include the second advancing extraction front. Soils encountered during extraction will vary over the location in depth and extent. Actual soil variations, depths and descriptions, including potential volumes to be extracted, are detailed in Exhibit I & J: Soils and Vegetation Information, and are shown on Exhibit I & J: Soil and Vegetation Map. The soil volumes essential for reclamation of affected lands remaining above the anticipated static water level (4795 '± elevation) of the completed basins will be salvaged and stockpiled from a portion of the upper six inches of the native soil profile (the `topsoil'). The remaining soils found within the solum or generated by plant processing activities, and in excess of that required for reclamation of affected lands, will be utilized for sale to help satisfy the infrastructure and development demands of the surrounding community. As indicated in Exhibit E — Reclamation Plan; of the 101 .97± acres of potential extraction, the resulting basins will function as reservoirs with a water surface covering 90. 87± acres. This leaves a balance of 11 . 10± acres (4.30± acres West Basin & 6.80± acres East Basin) of affected land within the extracted basins above the anticipated static water level . When combined with 34.00± acres of Mineral Reserve Areas used for support operations, a potential 45 . 10± acres may require resoiling and revegetation over the life of the operation. Initial resoiling and revegetation burdens are actually far less, since full build out takes up to 30-35 years to complete. Tract A (West Basin) at full build out has 4.30± acres of affected land within the extracted basin and above the anticipated static water level at the completion of operations. Since the 24.00± acres Mineral Reserve Area (2) will not be affected until and unless the 10.00± acres Mineral Reserve Area ( 1 ) becomes crowded or extracted. The initial area requiring resoiling and revegetation for the full build out of Tract A and disturbance to the 10.00± acres Mineral Reserve Area ( 1 ) is 14.30± acres, and is provided for under Exhibit L — Reclamation Costs. The primary end use for the extracted basins is developed water resources, however, the balance of lands remaining above the anticipated static water elevation of the basins, and not otherwise occupied, will be later developed to the Varra Companies, Inc. OMLR 112 Permit Application 6 Parcel 122 — Resource Development Project 1 July 2015 Exhibit D- Mining Plan highest possible end-use. End use may vary over the reclaimed lands and will comprise a variety of mixed uses. Mixed use may include other agricultural uses; as well as light residential, commercial, or industrial uses. While the on-set of reclamation is concurrent with extraction, the completion of reclamation may lag up to five (5 .0±) years behind the onset of reclamation activities. Complete extraction of the permit area is expected to take approximately 25-30 years, depending upon market conditions, with an additional 5 years following completion of all extraction activities for ultimate completion of concurrent reclamation activities, placing the completion of all activities near. 2045-2050, depending upon the date of start-up. Varra Companies, Inc. OMLR 112 Permit Application 7 Parcel 122 — Resource Development Project 1 July 2015 Exhibit E — Reclamation Plan 6.4.5 EXHIBIT E - Reclamation Plan ( 1 ) In preparing the Reclamation Plan , the Operator/Applicant should be specific in terms of addressing such items as final grading (including drainage) , seeding , fertilizing, revegetation (trees, shrubs, etc.) , and topsoiling . Operators/Applicants are encouraged to allow flexibility in their plans by committing themselves to ranges of numbers (e.g . , 6"- 12" of topsoil) rather than specific figures. (2) The Reclamation Plan shall include provisions for, or satisfactory explanation of, all general requirements for the type of reclamation proposed to be implemented by the Operator/Applicant. Reclamation shall be required on all the affected land . The Reclamation Plans shall include: (a) A description of the type(s) of reclamation the Operator/Applicant proposes to achieve in the reclamation of the affected land , why each was chosen , the amount of acreage accorded to each , and a general discussion of methods of reclamation as related to the mechanics of earthmoving ; (b) A comparison of the proposed post-mining land use to other land uses in the vicinity and to adopted state and local land use plans and programs. In those instances where the post-mining land use is for industrial , residential , or commercial purposes and such use is not reasonably assured , a plan for revegetation shall be submitted . Appropriate evidence supporting such reasonable assurance shall be submitted; (c) A description of how the Reclamation Plan will be implemented to meet each applicable requirement of Section 3 . 1 ; (d) Where applicable , plans for topsoil segregation , preservation , and replacement; for stabilization , compaction , and grading of spoil; and for revegetation . The revegetation plan shall contain a list of the preferred species of grass, legumes, forbs, shrubs or trees to be planted , the method and rates of seeding and planting , the estimated availability of viable seeds in sufficient quantities of the species proposed to be used , and the proposed time of seeding and planting ; (e) A plan or schedule indicating how and when reclamation will be implemented . Such plan or schedule shall not be tied to any specific date but shall be tied to implementation or completion of different stages of the mining operation as described in Subparagraph 6.4 .4( 1 )(e). The plan or schedule shall include: (i) An estimate of the periods of time which will be required for the various stages or phases of reclamation; (ii) A description of the size and location of each area to be reclaimed during each phase; and (iii) An outline of the sequence in which each stage or phase of reclamation will be carried out. (The schedule need not be separate and distinct from the Reclamation Plan , but may be incorporated therein .) (f) A description of each of the following: Varra Companies, Inc. OMLR 112 Permit Application 1 Parcel 122 — Resource Development Project 1 July 2015 Exhibit E — Reclamation Plan (i) Final grading - specify maximum anticipated slope gradient or expected ranges thereof; (ii) Seeding - specify types, mixtures, quantities, and expected time(s) of seeding and planting; (iii) Fertilization - if applicable, specify types, mixtures, quantities and time of application; (iv) Revegetation - specify types of trees, shrubs, etc. , quantities, size and location; and (v) Topsoiling - specify anticipated minimum depth or range of depths for those areas where topsoil will be replaced . This application provides substantial detail of features by utilizing aerial photography ortho-rectified to near survey accuracy. This highly accurate and detailed portrayal of the mining and reclamation is visible under Exhibit C- 1 : Existing Conditions Map, Exhibit C-2 : Extraction Plan Map, and, Exhibit F — Reclamation Map. How reclamation will occur over affected lands is further detailed under Exhibit L — Reclamation Costs. As extraction progresses over planned areas in Tracts A and B ; the resulting 1 .25H: 1 V or flatter slopes created during extraction will be concurrently modified by pushing the resulting pit bottom with a dozer until the resulting basin slopes conform with Rule 3 . 1 .5(7). Lands above the anticipated final water level of the basins and within 10.0+ feet below the anticipated final water level of the basins will be graded to 3H: 1 V, or flatter. Lands below 10.0+ feet from the anticipated final water level of the basins will also be graded to 3H: 1 V, or flatter. Naturally occurring slopes may exceed 2H: 1 V where not otherwise affected by extraction activities and will not be altered as part of reclamation unless necessary to facilitate the reclamation of affected lands. A Backfill Notice is included with this application as an Addendum at the back of Exhibit E — Reclamation Plan, to facilitate the use of inert fill over portions of the extracted lands to accomplish final end-use potentials, reservoir storage, and other mixed uses, which may include residential, commercial or industrial structures or uses otherwise approved now or in the future by Weld County, Colorado. The extent and nature of the reservoir represents the maximum build-out respective of optimal extraction of commercial product and resulting final slopes. All affected lands remaining above the anticipated high water mark of the finished reservoirs will be capped with a minimum of six (6.0±) inches of soil, as supported by Exhibit I & J - Soils and Vegetation Information. Timing and use of soil is Varra Companies, Inc. OMLR 112 Permit Application 2 Parcel 122 — Resource Development Project 1 July 2015 Exhibit E — Reclamation Plan detailed further under Exhibit I & J - Soils and Vegetation Information and Exhibit L — Reclamation Costs. Where compacted lands requiring revegetation exist, those locations will be ripped prior to re-soil application. There are no known areas of compaction at the time of this application which would require such activity; and ripping remains a contingency of the application. The final land configuration resulting from completed extraction will create the Primary End Use of Developed Water Resources, forming two reservoir basins totaling 101 .97± surface acres as shown on Exhibit F: Reclamation Map. The West Basin of Tract A comprises 55 .25± acres and will create a surface water area of 49.64± acres at full build out. The East Basin of Tract B is 46.76± acres and will create a surface water area of 41 .23± acres at full build out. Since the existing lands comprised predominantly of crops, ornamental, or introduced species; disturbed lands remaining above the static water level of the basins (4795 ' elevation), will be revegetated with an enduring stabilizing cover of predominantly native grasses (refer to Exhibit E - Table E- 1 : Primary/Preferred Re-vegetation Seed Mixture). An optional seed mixture is provided under Exhibit E - Table E-2 : Optional/Default Revegetation Seed Mixture. This optional mixture provides for the use of other genetic potential and species combinations under failed conditions consistent with the seed mixture utilized over the pre- disturbed lands. A wheat x wheatgrass sterile hybrid will be combined with either applied mixture as a substitute for the use of mulch to aid establishment of newly seeded areas. The target for release of revegetated lands is based upon the establishment of a stabilizing cover of predominantly native vegetation whose foliar umbrella equals or exceeds 25 percent of the total area of the ground as measured one inch above the native soil on a square meter basis for typical areas of reclaimed cover achieved within five years subsequent to the completion of all extraction activities. Lands not otherwise occupied for use as Developed Water Resources will be later developed to the highest possible end-use, and will likely comprise mixed agricultural, light residential, commercial or industrial uses. Mixed use(s), may also include, but are not limited to: the retention of existing structures as desired (e.g., portable or fixed concrete batch plant, asphalt batch plants, recycling facilities and related structures, shop, scale-house/office; and supporting facilities such as fuel depots, parking areas, oil and gas facilities access, etc.) for continued industrial - commercial uses; the creation of unforeseen future Varra Companies, Inc. OMLR 112 Permit Application 3 Parcel 122 — Resource Development Project 1 July 2015 Exhibit E — Reclamation Plan structures, and for the use and development of on-site water resources. Since the area of surrounding lands is a mix of these uses, the site end use will retain these potentials. The rate of reclamation activity, including grading, soiling and revegetation will follow concurrently with extraction and the respective timetables identified for extraction under Exhibit D — Mining Plan. All timetables are contingent upon market conditions. With extraction activities anticipated to take up to 25-30 years to complete, reclamation will add an approximately five years to this estimate, bringing the anticipated life of the mine to 25-30± years, or the year 2045 -50. The actual end point is five (5 .0±) years subsequent to the completion of all recoverable materials and successful release of all reclamation required under the approved State of Colorado Division of Reclamation Mining and Safety (DRMS) permit. A Backfill Notice follows this page, as part of this Exhibit. The use of inert fill will facilitate the timely fill of selected portions of the project areas, and related reclamation of affected lands and use of related water resources (refer to Exhibit L — Reclamation Costs). Varra Companies, Inc. OMLR 112 Permit Application 4 Parcel 122 — Resource Development Project 1 July 2015 Exhibit E — Reclamation Plan BACKFILL NOTICE Inert structural fill may be imported or utilized from existing sources, along with processing fines and reject material to fill portions of Tracts A and B -- the extent and location of which will be field determined during final reclamation in order to advance alternative end-use potentials for post extraction development. The estimated total volume of fill for this location is determined as follows: The date of fill activity will commence at onset of approval of this application, and continue for the life of the project, estimated at 30-35± years. Material will be mixed with on-site processing fines and reject prior to fill to eliminate void spaces, where necessary; or as otherwise utilized under recycling activities. The filled portions of a given tract will be re-vegetated with the approved seed mix. All material either extracted on site, or imported to the site, will be handled in such a manner so as to prevent any unauthorized release of pollutants to the surface drainage system. No unauthorized release of pollutants to groundwater shall occur from any materials mined, handled or disposed of within the permit area. I, Garret C. Varra, hereby attest that the material to be utilized as inert fill in the area described as Parcel 122, is clean and inert as defined in Rule 1 . 1 (20) of the Rules and Regulations. Arr,44.(nos...

(2) If the operation is expected to directly affect surface or groundwater systems, the Operator/Applicant shall: (a) Locate on the map (in Exhibit C) tributary water courses, wells, springs, stock water ponds, reservoirs, and ditches on the affected land and on adjacent lands where such structures may be affected by the proposed mining operations; (b) Identify all known aquifers; and (c) Submit a brief statement or plan showing how water from de-watering operations or from runoff from disturbed areas, piled material and operating surfaces will be managed to protect against pollution of either surface or groundwater (and, where applicable, control pollution in a manner that is consistent with water quality discharge permits) , both during and after the operation. (3) The Operator/Applicant shall provide an estimate of the project water requirements including flow rates and annual volumes for the development, mining and reclamation phases of the project. (4) The Operator/Applicant shall indicate the projected amount from each of the sources of water to supply the project water requirements for the mining operation and reclamation. (5) The Operator/Applicant shall affirmatively state that the Operator/Applicant has acquired (or has applied for) a National Pollutant Discharge Elimination System (NPDES) permit from the Water Quality Control Division at the Colorado Department of Health, if necessary. (1) Operations will directly affect surface and groundwater systems, as detailed under Exhibit D — Extraction Plan, and below. (2) (a) Please refer to Exhibit C- 1 : Existing Conditions Map. (b) The known aquifers under the site are the stream alluvium and the Laramie Fox Hills aquifer. (c) Please Refer to the AWES Dewatering & Basin Liner Report of 27 July 2015 . Discharge water will be dissipated with hard surface riprap or established grassed waterways. Other waters are retained by internal pit drainage, directed by vegetated berms or established waterways or through the maintenance or establishment of a stabilizing cover of vegetation. (3) The three components of the project water requirements are water removed with the product, dust control, and evaporation from exposed ground water. Dust will be controlled using truck sprinklers, and the estimated frequency is one load per day. At 3,000 gallons of truck capacity, the annual demand is 3 .36 acre-feet. After the water table is encountered, the water removed with the estimated 800,000 tons of product is 23 .55 acre-feet per year. The estimated net evaporation is 2.76 feet per year. At the maximum potentially exposed ground water of 96 acres, the annual evaporation is 263 acre-feet. Varra Companies, Inc. OMLR 112 Permit Application Parcel 122 -- Resource Development Project 1 July 2015 Exhibit G — Water Information The monthly distribution of these estimates is shown in the following table. The reclamation plan provides that the pits will be lined after being mined. The lined pits will not require replacement water and will be used for storage. There may be incidental demand for water to establish vegetation on the site after lining is completed. However, the ultimate demand for water will be zero. Dewatering will pump the ground water into the seepage ditch at an estimated rate of 7.2 million gallons per day.

OMLR 112 Permit Application 2 Parcel 122 — Resource Development Project 1 July 2015 Exhibit G — Water Information Water in excess of this mine's and other VCI obligations will be stored and used to replace the water use from November through March. The storage sites are lined pits described in Case No. 01 CW274 decree. Water available under this storage decree will also be stored and used for VCI operations. The storage facilities are listed in the following table. Those currently lined and approved by the state are 112, Von Ohlen, Dakolios East and Dakolios West. VCI STORAGE FACILITIES (All Values in Acre-Feet) Reservoir Active Capacity, a-f Dead Storage, a-f 112 2,000 0 Dakolios 1 ,900 0 Von Ohlen 1 ,300 0 Kurtz 4,000 0 (5) The Colorado Department of Health has issued Certification for a Colorado Wastewater Discharge Permit System Permit No. COG500000 Facility Number COG-501584. (6) The application provides for the lining of the extracted basins (please refer to the AWES Dewatering Evaluation Report of 27 July 2015). Lining will involve the utilization of suitably derived on-site materials to meet final 3H: 1V V slopes. Subsequently, the same materials may be compacted to satisfy standards for lined basins as established and governed by the Colorado Department of Water Resources Office of the State Engineer. Once operations near completion of any lined basin, the OSE will be contacted and the lined basins will be approved by the OSE prior to use. The OSE approval letter will be provided to the OMLR as a condition of the permit as evidence that the lined basin has met the specifications necessary to pass a liner test as part of the OSE approval process. Consistent with conclusion in the AWES Report, lining of the completed basins will have 'will have a de minimis effect on groundwater hydrology.' The report continues, adding that, `Predicted post lining head levels immediately up and downgradient of the barrier walls are within the range of normal seasonal water table elevation changes.'

Frederick, CO 80516 Fort Collins, CO 80524 PO SWES 4bt9 remStar Court, rust Collins, CCSC1524 Introduction The following report presents the results of a hydrogeologic evaluation regarding a proposed dry mine gravel quarry operation to be operated by Varra Companies (Varra) near Platteville, Colorado. Varra identifies the proposed mine as Pit 122. The evaluation consisted of reviewing available hydrogeologic data and inputting those data into a numerical groundwater flow model, The model was then used to estimate the effects of dewatering operations on the surrounding groundwater hydrology. This report was prepared as part of an OMLR 112 permit application. The site location is depicted on Figure 1. Background Information The proposed gravel quarry is located in the NW1/4, S33, T3N, R67W of the 6th Principal Meridian . The surrounding land use consists of agricultural, rural residential, commercial and open-cut gravel quarry operations. The proposed mine area occupies an estimated 102 acres and the anticipated average pit depth will be 39 feet below grade. Information provided by current mining operations data and water resource evaluation reports document the local and regional hydrogeology. In September 2008, 22 soil borings were drilled from ground surface to bedrock to determine the potential aggregate mass within the proposed mine boundary (Terracon 2008). Bedrock elevations were also obtained from studies by Colton and Finch, 1974. The depth to bedrock within the proposed mine boundary varied between 13 and 55 feet below ground surface. In general the site consists of three to eight feet of silty sand to sandy clay underlain by sand and gravel with occasional clay and poorly graded sand lenses. The hydraulic conductivity of the sand and coarse gravel deposits is on the order of 125 feet per day (Schneider, 1983) which is consistent with published values and pump test evaluations conducted by the author in similar geologic settings. The average effective porosity of the local sand and gravel deposits is estimated at 0.27. The natural hydraulic gradient as documented by past water resource investigation reports is on the order of 0.002 feet per foot, with the average depth to water estimated at six feet below ground surface. The natural groundwater flow direction is to the northwest within the model and mine area. Seasonal water table fluctuations of Dewatering Evaluation Report Varra Pit 122 Weld County, Colorado Page 2 between one and three feet are common for this area; however, fluctuations of greater than ten feet have been documented during drought conditions (Schneider, 1983). The water table in the pit will be drawn down to bedrock over an estimated 100 acres. The mine is dewatered by allowing groundwater to flow from the side walls of the excavation into ditches excavated into the bedrock or pit bottom at the toe of the excavation walls. The ditches are sloped so water drains to predetermined pump locations. The water is then pumped from the excavation into the Seep Ditch, which eventually outfalls to the Saint Vrain Creek. Varra Companies operates an active gravel mine ( Pit 116) immediately west of the proposed Pit 122. The pit is dewatered by similar methods as described above and groundwater recovered by dewatering is pumped into the Seep Ditch. The proposed Pit 122 has two cells (A and B), which may or may not be mined concurrently. Pumping simulations are provided for multiple cells in Pits 116 and 122. Project Assumptions The following are assumptions made in estimating the effects of mine dewatering operations. • The aquifer within the model boundary is homogeneous and anisotropic. • The average saturated thickness of the aquifer prior to mine operations is approximately 33 feet (average soil depth of 39 feet and average water table six feet below ground surface). • The average horizontal hydraulic conductivity (K) of the sand and gravel deposits is 125 feet per day and the vertical K value is 12.5 feet per day. Silty sands, which are present throughout the majority of the southern model boundary, were assigned a horizontal K of 50 feet per day and a vertical K of 5 feet per day. • The vertical conductivity of the unlined ditch beds varies between 0.4 and 4 feet per day. • Other than dewatering associated with the Pit 116 and proposed Pit 122 mine operations no other aquifer stresses such as drought and surrounding well use were modeled. • All groundwater solutions are steady state. • The bedrock which underlies the coarse alluvial deposits is an impermeable barrier. Dewatering Evaluation Report Varra Pit 122 Weld County, Colorado Page 3 Model Parameters The effects of dewatering on groundwater flow within the study area were evaluated by using the three dimensional groundwater flow model Visual ModFlow. The general parameters used in the model are presented below. Plates 1 through 3, depict model boundary conditions. • The model boundary is 8640 feet (east-west) by 9900 feet (north-south); • The model grid is 248 rows by 216 columns or 53,568 cells; • Constant head boundaries were assigned for the dewatering line sinks and for the pit interiors subsequent to lining; • River boundaries were assigned for the unlined ditches; • Barrier walls were assigned near the excavation limits of cells A and B in Pits 116 and 122 to simulate the lining of mined excavations; and, • General head boundaries were assigned to the model limits (north, south, east and west). A uniform flow field was defined in the model with an unconfined aquifer. The natural groundwater flow direction is to the northwest within the model boundaries. Water levels obtained from published water level data was used to generate water level contours unaffected by any pumping influences (pre-mining). Monitoring wells within the Pit 116 and Pit 122 mine boundaries were used to calibrate the model based on current conditions. Ground surface and bedrock elevations were obtained from site surveys, drill hole data and USGS maps. Ground surface and bedrock elevations were input into the geo-statistical model Surfer®, which created surface and bedrock contour maps. These maps were imported into Visual ModFlow to define the ground surface and bedrock elevations within the flow model. The river stage elevations (ditches) were estimated from survey and map data. As mentioned, constant head boundaries were used to simulate pumping from the proposed Pit 122 and the existing Pit 116. The model was calibrated by using model assigned observation wells inside and outside of the proposed excavations. A pumping simulation for Cell A of Pit 116 was ran using current elevations for the drainage ditches within the excavation. Measured water Dewatering Evaluation Report Varra Pit 122 Weld County, Colorado Page 4 levels (obtained from current monitoring well data) were compared to the model predicted elevations. The model was adjusted using trial and error methods of reassigning river boundary conductance and general head elevations until the model predicted water table elevations closely matched measured water levels. The calculated head values for the model assigned wells were then used as observed levels so that subsequent model simulations would predict changes to groundwater hydrology compared to the calibrated simulation. The calibration simulation included seepage from the river boundaries (ditches) and the pumping of cell A of Pit 116 — which is reflective of current field conditions. The calibration simulation is depicted on Plate 4. The observed head values referenced above are depicted on Plates 5 and 5A. As the mining at Pits 116 and 122 will likely be concurrent, multiple lining and dewatering scenarios were evaluated. Plates 6-11 depict the effects of concurrent mining and reclamation activities for pits 116 and 122. Varra intends to line cells A and B of Pits 116 and 122 for water storage (Plate 1). To evaluate the effects of lining the four cells on the local groundwater hydrology, barrier wails were assigned near the excavation limits of the referenced cells. Plate 12 depicts boundary conditions for the lined pits. Plate 13 depicts the calibration model output that was used to compare pre-mining to post mining water levels. Head elevations, obtained from the calibration runs, were recorded at six locations immediately up and downgradient of the pits as depicted on Plate 14. To simulate filled ponds, the interior of the reservoirs were assigned a constant head value of 4796 feet, which is slightly below ground surface. A simulation was then ran to predict the effects of the lined reservoirs on the groundwater hydrology. Plate 14 depicts the computer simulation output. Table 1, presents the predicted water level changes as a result of lining the mined out pits. Dewatering Evaluation Report Varra Pit 122 Weld County, Colorado Page 5 Table 1 — Lined Pit Water Level Comparison Points Point r Calibration Water Level Post Lining Water Level Elevation Difference 1 4790.97 4789.92 -0.1.05' 2 4790.23 4790.88 0.65' 3 4791.96 4792.28 0.32' 4 4795.62 4797.52 1.90' 5 4798.97 4799.80 0.83' 6 4797.69 4799.06 1.37' Results A review of plates 7-11 show that the groundwater hydrology less than one-half mile east of Pit 122 is not affected by any pumping scenario. The model predicts a drawdown of 4 to 5 feet 1,500 feet north of Pit 122 and similar conditions approximately 1,000 feet south of Cell B in Pit 116. The cessation of pumping from Cell A of Pit 116 appears to allow recharge to the west of the pit. The lining of this pit may also create a protective barrier (to the west) to pumping associated with Pit 122. A review of Table 1, shows that the lining of mined pits will have a de minimis effect on groundwater hydrology. Predicted post lining head levels immediately up and downgradient of the barrier walls are within the range of normal seasonal water table elevation changes. Conclusions The results of analytical and numerical solutions indicate that the proposed mine dewatering activities will not adversely affect the regional groundwater hydrology. With the exception of shallow alluvial deposits just to the west of Pit 122, the saturated aquifer thickness in all other areas outside of the Pit 122 development is sufficient to provided adequate well yields. The predicted drawdown associated with the Pit 122 mine dewatering model represents the worst Dewatering Evaluation Report Varra Pit 122 Weld County, Colorado Page 6 case scenario and a substantial amount of time will be required before maximum drawdowns will occur. In the author's opinion one cannot reasonably differentiate the head differences of seasonal groundwater fluctuations and head differences possibly created by fining mined pits — they are within expected seasonal head variations expected for geologic settings of this kind. The permeability of the aquifer materials adjacent and in between the extraction areas are sufficient to mitigate pressure gradients created by the impermeable liners. This type of analysis is also complicated by the numerous aquifer stresses and aquifer gains which occur in close proximity to the extraction developments — making any conclusion a best guess. As there are domestic wells located within the area influenced by pumping, it may be advisable to conduct a physical well survey prior to the mine start-up. Though there is sufficient aquifer thickness to provide good well yields in most areas there may be partially penetrating wells that might be affected by mine dewatering.

The Operator/Applicant shall include in this Exhibit, a description of the game and non-game resources on and in the vicinity of the application area , including : (a) a description of the significant wildlife resources on the affected land ; (b) seasonal use of the area; (c) the presence and estimated population of threatened or endangered species from either federal or state lists; and (d) a description of the general effect during and after the proposed operation on the existing wildlife of the area, including but not limited to temporary and permanent loss of food and habitat, interference with migratory routes, and the general effect on the wildlife from increased human activity, including noise. (2) The application may be reviewed and commented upon by the State of Colorado Division of Wildlife (DOW). If the DOW has comments, they must be provided prior to the end of the public comment period specified in Subsection 1 .7. 1 (2)(a) to be considered by the Board and Office. Recent policy of the Division of Parks and Wildlife ( DOP&W) no longer provides for a pre-submittal report. Also note that reference to the project area as Bearson is a relic, and use of the name applies to the same area, location, and intent described now as Parcel 122; as identified within this Exhibit H, or to any correlated Exhibits or attachments associated with this permit application. Wildlife residents and visitors observed on area lands include hawks and other birds of prey; and passerines (song birds) . Game species such as white tailed deer will traverse the area; as will other fur bearers such as fox, rabbit, and squirrels; non-game species such as rodents. The existing lands were highly modified by past agricultural practices and crops. Wildlife should find benefit from the future reclamation as attributed to a new water bodies and return of cover to predominantly native vegetation . Temporary displacement of wildlife within the planned extraction limits may occur until the reclaimed vegetation matures and reclaimed basins fill with water. We anticipate any DOP&W written determinations will support our understanding that there is little if any potential for adverse impacts to wildlife resulting from planned operations. Further, planned reclamation is well correlated with DOP&W perspectives, and will serve to provide a number of benefits to various wildlife species, especially waterfowl, including a return of native vegetation, cover, and creation of water bodies that will serve as additional sources for food, cover, and resting surfaces. The planned seed mixture will further add to the diversity of height, form, color and function of the resulting vegetative cover. Varra Companies, Inc.

CO 80534 Hearson Property Rare Plant Survey (.\ Yrr•ccrr/hc• s clrlrrtivrrlr,0 Dear Mr Janes • As \soci had requested, i have completed a survey of the Hearson tract north of Frederick and south of (rowanda, searching for habitat and plants for the federally threatened plant species lite ladies - - tresses orchid ( Spin/tithe.% clilm'uili., ). Pans of the property are on the floodplain of St . Vrairi Creek. and parts are on uplands, away from the floodplain . The site is the northwest quarter of section 33 , "1'3N Rb7W. roughly 160 acres, and is shown on the (lowanda 7. 5 - Quadrangle. The property measures approximately' one-half mile north-south and one-half mile east-west Hie northwest corner of the property is at the southeast corner of the intersection of Weld County Roads 17 and 28. the surveyed area excludes the 1.3earson homestead and outbuildings The survey was completed on July 26, 2012, a hot summer day Assisting on the survey was Robert E. Jennings Bradford Janes of Varra was present during most of the survey. The Varra Companies are planning to develop gravel mining operations on the property _ which is currently used for agricultural purposes Several gas wells are present. The area is generally open country, but the town of Frederick is rapidly developing northward toward t}ie properly. Rite orchid blooms in July and August; usually commencing bloom about July 20. By mid- September the orchid is in fruit . If no frosts have occurred. the plant is green and erect in early tall . but tends to blend into the surrounding greenery. When in bloom , porcelain white flowers immediately call attention to the plant During winter and spring, the plant is not visible or is visible only as a dime-sized over-winter rosette. On the date of the survey, the orchid ' s normal blooming season had commenced the week previous. (-)n July 19, orchids were seen in bloom at a well-known site in Jefferson County. It• present during the survey. the orchid would have been in bloom, and should have been noticeable. No orchids were found during the survey. The extreme southern portion of the property is an upland area away from the iloodptain, and is fair too dry to constitute orchid habitat No irrigation is available for this portion of the property. Geologically, this area is very sandy , and is probably ofaeolian origin (wind-blown sand). Plants noted included sand sage (.-4r-remtviu.Jrlifolru ), prickly poppy ( ir< em une l?olviltrrllr'n os, and blazing Star ( Met/tent' burr ).. all common plants of sandy areas on the plains. The northern potion of the property is at lower elevation than the extreme southern portion . Although the channel of St . Vr in creek is nearly a mile to the northwest of the northwest corner of the property, this portion of the tract appears to be part of the tloodplain. Nearly all of this area has been intensively used for agricultural production, barge areas both east and `vest of the farmhouse are currently planted in corn. Irrigation ►mater is present. as a ditch crosses the southern potion of the property and another follows the west boundary of the property. Numerous feeders and laterals have been developed in this portion of the tract Some of these ditches are concrete- lined, and it is obvious that the area has long been used for irrigated agriculture 'l he• unlined ditches are typical of irrigation ditches, and show steep banks, with no areas of overhaul; flooding or wetlands immediately adjacent to the ditches. The banks of the ditches are covered with a luxuriant growth of reed eanarygr ss ( l'/uilan► arwulrnuee'u ). with some scattered patches of showy milkweed ( .4.►i /c'f it,y .c/)ecro.tisa). There is no habitat for orchids in this area, either in the irrigated cornfields or along the ditches and laterals. Windbreaks have been developed at several locations on the property, but these areas are planted in trees and shrubs and are generally dense in revegetation grasses. There is no habitat for orchids in these areas. There are two areas on the 1.3carson property that were potential orchid habitat. in the northeast corner of the property, there is a cattail marsh that appears to be natural, and is a It' s feet lower than the surrounding area. Similarly, south of the house is a linear feature ( east-west ) that could be the remnant of an old stream channel. I-3oth areas were examined closely, but no orchids were found The marsh at the northeast corner of the property is composed largely of cattails 7:iph t lira/h/ur) in the lowest part of the marsh, surrounded by a zone composed mostly of three-square ( \c/uiem plec'lrrc /nmgenns)_ The wettest portions of the marsh are too densely vegetated with cattails or are too wet for orchids to occur. The southern portion of the marsh was surveyed closely. "['hen the north and east sides were checked_ The only potential habitat is on the south side of the marsh, generally near a patch of swamp milkweed (Asclepius irrcarmita), where the ground water table appears to be maintained at a high level. similar to other areas where the orchids occur. However, no orchids were found. I--he old stream channel south of the farmhouse is very low compared to the surrounding area. There are areas of cattails and standing water, apparently stagnant. There was a luxuriant growth of duckweed ( Lemma species) on the standing water_ There was evidence of ground water evaporation in the form ofalkaline salt encrustation on some plants. None of the common 7 associates of the orchid were thund. No orchids were found. Habitat is considered to be very marginal in the old stream channel area. In 11W opinion, any construction or gravel mining will not impact the orchid Although marginal habitat is present, only one of the commonly associated species was seen (Asclepius mew-t urea ) Much of the native vegetation has been removed due to intensive agricultural usage. Other surveys in the Gowanda vicinity along St. Vrain Creel: have been negative . This letter should he of assistance in obtaining the permits necessary from the US Fish & Wildlife Service and the US Army Corps of Engineers. Sincerely,.4 , /A I - QA-/' 4 ‘ . .1 ; 3,4k ' ‘.

(Varra) plans to conduct aggregate mining operations on 152.88 acres of agricultural land in southern Weld County (Bearson property). As part of their planning and permitting process, Varra contracted ER0 Resources Corporation (ERO) to perform surveys for Preble's meadow jumping mouse (Preble's) and other federally listed threatened and endangered species (listed species). This report describes current regulatory guidelines related to federally listed threatened and endangered species and survey results for listed species and/or habitat identified on the Bearson property during a 2012 site visit. Objectives and Project Location The purpose of this assessment is to determine the presence or absence of threatened and endangered species habitat, including Preble's habitat on the Bearson property (Figure 1 ). The project arca is in the NW ''A of Section 13, T3N, R67W of the 6th Principal Meridian, Gowanda 7%2-minute U.S. Geological Survey (USGS) quadrangle in Weld County, Colorado (Figure 1 ). The UTM coordinates for the approximate center of the project area are 508480mE, 4448396mN, Zone 13N. The project area is south of County Road 28 and east of County Road 17 in Platteville, Colorado (Figure 1 ). The majority of the project area consists of agricultural fields, with an existing farmhouse in the center of the project area. Two natural gas wells are in the project area. Regulatory Framework - The Endangered Species Act Federally threatened and endangered species are protected under the Endangered Species Act of 1973 (ESA), as amended ( 16 U.S.C. 1531 et seq.). Significant adverse effects to a federally listed species or its habitat require consultation with the U.S. Fish and Wildlife Service (Service) under Section 7 or 10 of the ESA. No regulations require 1 c:\users\special projects\documents\word 2005\bearson\preble\bearson preble's habitat assessment.doc THREATENED AND ENDANGERED SPECIES HABITAT ASSESSMENT BEARSON PROPERTY WELD COUNTY, COLORADO consultations for effects to candidate species; however, if a species were to become listed during project planning or construction, consultation with the Service would be required. Current Service guidelines describe occupied Preble's habitat as an area 300 feet beyond the 100-year floodplain for a distance of 1 mile upstream and downstream of a known population of Preble's. The Service requires surveys for Ute ladies'-tresses orchid (ULTO) in areas of suitable habitat in Colorado on the 100-year floodplains of the South Platte River, Fountain Creek, and Yampa River and their perennial tributaries (Service 1992). Methods Ron Beane, Senior Wildlife Biologist, and Moneka Worah, Natural Resources Specialist, with ERO performed an endangered species habitat assessment on the Bearson property in Weld County on July 12, 2012 (2012 site visit). In addition to the information gathered during the 2012 site visit, information on threatened and endangered species was obtained from existing sources such as the Colorado Natural Diversity Information Source (NDIS), known locations of Preble 's populations and survey efforts (Service 2011 ), the Colorado Natural Heritage Program (CNHP), and other sources. Based on the information gathered from existing sources and the 2012 site visit, ERO identified existing vegetation communities and important habitat attributes of the project area for the listed and candidate species listed in Table 1 (Figure 2). 2 THREATENED AND ENDANGERED SPECIES HABITAT ASSESSMENT BEARSON PROPERTY WELD COUNTY, COLORADO Table 1 .

Ecological Features of the Project Area Vegetation The project area is within the St. Vrain valley characterized by fertile alluvial soils that have been intensively farmed for decades. The project area contains no natural drainages of tributaries and ditches are largely concrete lined and lack tall, dense riparian vegetation. A concrete-lined lateral of the Last Chance Ditch flows northward across the project area toward St. Vrain Creek. Irrigation return flows support a large wetland in the northeast corner of the property (Wetland 1 ) and another wetland (Wetland 2) occurs in the southeast section of the project area (Figure 2). Wetland I is dominated by common threesquare (Scheonoplectus pungens), saltgrass (Distchilis spicala), foxtail barley (Hordeurnjubatuna), cattail (Typha sp.), curly dock (Rumex crispus), spikerush (Eleocharis palustris), alkali muhly (Muhlenbergia aspen:Jolia), goosefoot (Chenopodium sp.), and softstem bulrush (Scheonoplectus lactustris) (Photos 1 and 2). Natural and planted windbreaks consisting of narrow patches of peachleaf willow (Salix anlygclaloides) sandbar willow (Salix exigua) and young cottonwood occur on the east 3 THREATENED AND ENDANGERED SPECIES HABITAT ASSESSMENT BEARSON PROPERTY WELD COUNTY, COLORADO side of the wetland (Photo 3). Wetland 2 is dominated by cattail, common threesquare, and Emory sedge (Cares e►noryi) (Photo 4). The uplands in the project area are dominated by ragweed (Ambrosia artemisiifolia var. elation), kochia (Bassin sieversiana), smooth brome (Brontopsis inermis), western wheatgrass (Pascopyrum smithii), cheatgrass (Anisthana teetorum), and intermediate wheatgrass (Thinopyrum into-medium). A small prairie dog colony occurs in a portion og the upland habitat along the southern boundary of the project area. A ditch occurs in the southern portion of the project area with large plains cottonwoods lining the ditch. Two planted windbreak areas occur on the property with a mix of planted trees interspersed with volunteer native vegetation. One windbreak is in the southwest corner of the property and the other is along the northern boundary curving around the northwest corner (Photo 5). Preble's Meadow Jumping Mouse Species Background Preble's was listed as a threatened species on May 13, 1998 under the ESA (63 Fed. Reg. 66777-66784, December 3, 1998). Under existing regulations, either a habitat assessment or a full presence/absence survey for Preble's is required for any habitat- disturbing activity within areas determined to be potential Preble's habitat (generally stream and riparian habitats along the Colorado Front Range and southeastern Wyoming). Typically, Preble's occurs below 7,600 feet in elevation, generally in lowlands with medium to high moisture along permanent or intermittent streams and canals (Meaney et al. 1997). Preble's occurs in low undergrowth consisting of grasses and forbs in open wet meadows, riparian corridors near forests, or where tall shrubs and low trees provide adequate cover (Service 1999; Meaney et al. 1997). Critical Habitat Critical habitat identifies specific areas, both occupied and unoccupied, that are essential to the conservation of Preble's and that may require special management 4 THREATENED AND ENDANGERED SPECIES HABITAT ASSESSMENT BEARSON PROPERTY WELD COUNTY, COLORADO considerations or protections. Section 7 of the ESA prohibits destruction or adverse modification of critical habitat by any activity funded, authorized, or carried out by any federal agency, such as issuance of a Section 404 permit. In 2010, the Service revised its designation of critical habitat for Preble's and does not include any areas along St. Vrain Creek or its tributaries in Weld County (75 Fed. Reg. 78481 , December 15, 2010). Potential Habitat and Possible Effects Vegetation community types and habitat connectivity are the key elements in determining the suitability of habitat in the project area to support viable populations of Preble's. Although the project area contains herbaceous wetlands and planted windbreaks that replicate woody riparian habitat providing some of the habitat features described above for Preble's, these narrow vegetation communities are completely isolated and fragmented from potentially suitable habitat along St_ Vrain Creek. A review of aerial photography also revealed that most of the windbreaks are fairly young and poorly developed as recently as 1999. Furthermore, the area identified as Wetland 1 was mowed or hayed as recently as 2004. A survey field data compilation form is provided in Appendix A. Colorado Butterfly Plant Species Background The Colorado butterfly plant (CBP) is federally listed as threatened. The CBP is a short-lived perennial herb found in moist areas of floodplains. It occurs on subirrigated, alluvial soils on level or slightly sloping floodplains and drainage bottoms at elevations from 5,000 to 6,400 feet. The CBP is found in active floodplains along perennial streams and where vegetation is relatively open. Colonies are often found in low depressions or along bends in wide, active, meandering stream channels that are periodically disturbed (Service 2004). Its historical and current distribution in Colorado includes Boulder, Douglas, Larimer, and Weld counties. The CBP flowers from June to September and produces fruit from July to October (Spackman et al. 1997). 5 THREATENED AND ENDANGERED SPECIES HABITAT ASSESSMENT BEARSON PROPERTY WELD COUNTY, COLORADO Potential Habitat and Possible Effects Suitable habitat for the CBP is not present within the Bearson property because the property is not within an active floodplain. Ute Ladies'-Tresses Orchid Species Background The ULTO is federally listed as threatened. Once thought to be fairly common in low-elevation riparian areas in the interior western United States, ULTO is now rare (Service 1992). ULTO occurs at elevations below 6,500 feet in moist to wet alluvial meadows, floodplains of perennial streams, and around springs and lakes where the soil is seasonally saturated within 18 inches of the surface. Generally, the species occurs where the vegetative cover is relatively open and not overly dense or overgrazed. ULTO does not bloom until late July to early September (depending on the year) and timing of surveys must be synchronized with blooming (Service 1992). Potential Habitat and Possible Effects There is no suitable habitat to support potential populations of ULTO in the project area within the Bearson property because the property is not within an active floodplain. In addition, vegetation in the wetland and windbreak/riparian areas is dominated by species not typically found with ULTO and the vegetation is most likely too dense to allow establishment of a new population of ULTO in the project area. Past Studies Several trapping surveys for Preble's have been conducted since 1998 on both the lateral ditch that crosses the project area and the main Last Chance Ditch north of the project area (Service 2011 ). No Preble's have been found in nine trapping surveys on these ditches recorded by the Service (Service 2011 ). Furthermore, no Preble's have been found during an additional 14 trapping surveys that have been conducted in better habitat within the St. Vrain Creek floodplain between Interstate 25 and the confluence with the South Platte River (Service 2011 ). The nearest known location of Preble 's is more than 6 THREATENED AND ENDANGERED SPECIES HABITAT ASSESSMENT BEARSON PROPERTY WELD COUNTY, COLORADO 15 miles upstream on St. Vrain Creek or about 9 miles north on the Little Thompson River. Conclusions and Recommendation Based on the information provided in this assessment and summarized below, ERO requests that the Service disqualify the Bearson property for consideration under the provisions of the ESA. Preble's Meadow Jumping Mouse Although the vegetation bordering Wetland I has some of the characteristics of suitable Preble's habitat, the area is highly unlikely to support a viable population of the species for the following reasons: I . There are no natural drainages or streams on the project area and ditches are concrete-lined and sparsely vegetated. 2. Wetlands and wooded windbreaks on the project area are fairly young (20 years) and are primarily planted or a result of recent irrigation practices. 3. There is no connectivity to suitable Preble's habitat along St. Vrain Creek. 4. Extensive trapping efforts on ditches immediately adjacent to the property and along St. Vrain Creek near the property have been negative. 5. The nearest known occurrence of Preble's is about 9 miles away on a different drainage. Colorado Butterfly Plant and Ute Ladies'-Tresses Orchid The Bearson property does not support potential populations of CBP or ULTO because the property in not within an active floodplain and does not satisfy the criteria for suitable habitat.

Such description will address suitability of topsoil (or other material) for establishment and maintenance ofplant growth . The above information shall satisfy "completeness" requirements for purposes of determination of date of filing. (2) If necessary, at its discretion , the Board may require additional information on soils or other growth media to be stockpiled and used in revegetation to be submitted subsequent to the filing and notification of "completeness" of the application . 6.4.10 EXHIBIT J - Vegetation Information (1 ) The Operator/Applicant shall include in this Exhibit a narrative of the following items: (a) descriptions of present vegetation types, which include quantitative estimates of cover and height for the principal species in each life-form represented (i.e. , trees, tall shrubs, low shrubs, grasses, forbs); (b) the relationship of present vegetation types to soil types, or alternatively, the information may be presented on a map; and (c) estimates of average annual production for hay meadows and croplands, and carrying capacity for range lands on or in the vicinity of the affected land , if the choice of reclamation is for range or agriculture. (2) The Operator/Applicant shall show the relation of the types of vegetation to existing topography on a map in Exhibit C. In providing such information , the Operator/Applicant may want to contact the local Soil Conservation District. Exhibit I & J - Soils & Vegetation Map, identifies the type and extent of soils over the project site relative to the areas designated for resource recovery. The potential volume of soil to be removed for sale or retention for final reclamation is identified under Table I- 1 : Soil Volumes. While the native vegetation has been replaced by agricultural practices to irrigated crops (recently, corn), range site descriptions for each soil type are included at the back of this exhibit. The range site descriptions indicate what species of vegetation could grow on the identified soil under native conditions. This information was utilized to create the seed mixtures proposed under Exhibit E - Table E- 1 : Primary/Preferred Re-vegetation Seed Mixture and Exhibit E - Table E-2 : Optional/Default Revegetation Seed Mixture. For clarity, topsoil is generally regarded as the plow layer (upper six inches) on agricultural soils, or the A- 1 soil profile horizon otherwise. The solum, or soil Varra Companies, Inc. OMLR 112 Permit Application Parcel 122 — Resource Development Project 1 July 2015 includes the topsoil plus all other material above the regolith of the parent rock and generally no deeper than the depth of rooting of perennial plants or which otherwise meets the definition of. soil. One soil differs from another soil by its unique properties and characteristics (such as profile horizon development, structure, texture, color, percent organic matter, chemical composition, etc.) and is identified as such by soil scientists, and described in MRCS Soil Survey documents. Soil salvage will commence with the removal of the surface layer of soil to a minimum depth of 6.0± inches. Where the A- 1 or Ap (plow layer) is absent, any portion of the A and or B horizon of the solum suitable for plant regrowth will be utilized to meet the minimum depth of soil replacement for reclamation, with the excess made commercially available for export from the property. Where a C profile exists, it will be considered part of the regolith or deposit and extracted for processing. All excess soil will be subject to processing or stockpiling for commercial sale. Regardless, topsoil, or suitable volumes of the A and/or B profile where topsoil is absent, will be retained in sufficient volume to reclaim all lands remaining above the anticipated water level at any given point in time during resource recovery operations. To minimize the undesirable effects of soil blowing and loss, and to avoid damage to the soil resource via compaction, soil will be stripped wherever possible when soil is moist, and not dry or wet. Since the soils of the upper terrace of this location have been irrigated, salvage of soil below one foot in depth will not be used as a soil resource over the affected lands without first testing for the accumulation of salts that may affect the regrowth potential on those soils. Salt laden layers of the solum may be used as fill on-site and will be placed deeper than the primary root zone of grasses, trees, and shrubs, or generally, deeper than 4.0± feet in depth. Once removed from its native location, soil retained for reclamation will be windrowed along the perimeter of the area of extraction and seeded with the reclamation seed mixture specified under Exhibit E - Table E- 1 : Primary/Preferred Re-vegetation Seed Mixture. This will provide an opportunity to gage the performance of the seed mixture while attempting to provide a stabilizing cover of vegetation over the stockpiles soil until it is ready for replacement on finished slopes and affected lands remaining above the anticipated final water level of the completed reservoir basins. Varra Companies, Inc. OMLR 112 Permit Application Parcel 122 — Resource Development Project 1 July 2015 Windrowed salvage soil stockpiles will be graded such that the side slopes are 3H: 1 V or flatter. This will aid seeding and vegetation efforts while reducing the profile exposure of the stockpile to wind and water erosion, keeping the material stable until used for reclamation. Direct precipitation from short duration, high intensity rainstorm events, and wind, are the major threats to soil stability at this location. Although the location is nearly a table, and although the extraction will result in basins that cause water from direct precipitation to drain internally, additional measures will be taken to assure site stability and protection of off-site areas. The measures taken to stabilize the soil stockpiles, as described above, should be adequate for controlling erosion from wind and direct precipitation. Due to the flat topography of the upper terrace of Tracts A and B, and the interception of upland overland flows by the seep ditch and irrigation ditch that intersects these tracts, there is little upland watershed that would impact these locations. The greater threat of erosion will be to resoiled slopes pending establishment of vegetation during reclamation. While some rilling can be anticipated on unprotected areas following seed bed preparation and seeding, the conservation measures provided below should help to limit erosion potential that would threaten the revegetation efforts. Prior to resoiling, the foundation material that will underlie the soil will be sculpted to establish initial soil stabilization features, and left rough to aid in resoil adherence. Soil will be placed over an 18± inch minimum friable, or otherwise unconsolidated, subsoil. An 18± inch swale with slopes of 3H: 1V or flatter will be placed above finished slopes where necessary to direct any upland surface flows around the finished slopes to an established stable drainage corridor. Resoiled areas will be allowed a minimum of three months to settle prior to seeding. Seeding will follow in the fall or spring as detailed under Exhibit E — Reclamation Plan. Resoiling will occur when soil moisture is adequate to prevent blowing, yet dry enough to prevent compaction. Part of the soil rebuilding process on the reconstituted soils will be in establishing structure to the soils to facilitate plant-soil-water relationships. Overly compacted soils will tend to limit soil structure development and create a poor seedbed for later establishment. Once applied to the surface, the new soils will be exposed to the raw forces of erosion until adequate vegetative cover and root mass develops. Erosion requires both detachment and transportation in order to occur. Running water, wind, and Varra Companies, Inc. OMLR 112 Permit Application Parcel 122 — Resource Development Project 1 July 2015 raindrop impact are the main forces of erosion acting upon the soil. The use of a sterile hybrid live cover crop will aid in the stabilization of the soil by allowing a quick vegetative cover to become established in advance of the native grasses. The hybrid will also serve as an aid to reduce competition resulting from the establishment and growth of unwanted pioneer species (weeds) on disturbed ground. The attending reclamation seed mixture has a provision for the use of a sterile hybrid in lieu of mulch. Mulch, even when crimped with specialized equipment, is subject to being blown off the property, or reduced to ineffective stubble. Often, it has been observed to intercept rainfall where it quickly evaporates from the stubble surface, limiting the benefits of light precipitation by preventing infiltration and percolation of moisture to the root zone. The hybrid on the other hand will establish quickly but since it is sterile will not continue to compete with the emerging native grasses. After two to three years it will begin to die out just as the native grasses emerge and improve their dominance over the revegetated areas. Generally, the percent organic matter content (approximately 1 to 3 percent for native soils) of stockpiled soils will fall over time. If soil organic matter content falls below 1 percent, a minimum or the equivalent of two tenths of one percent (0.2%) of organic matter will be added to the soil at a rate of four (4) tons of manure per acre to the location in question. This should prove adequate to assure initial germination, establishment, and survival of the applied seed mixture, all other conditions (field available moisture, etc.) being satisfactory. The applied organics will aid in the restructuring of the new soils by increasing the moisture and fertility holding capacity of the upper profile while simultaneously facilitating root development of the emerging grasses. As the roots of the emerging grasses develop and mature over time, the resulting root mass will serve to add to the base percent organic matter content of the new soils over time, thereby increasing the potential for long term survival and spread of the established grasses. The addition of fertilizer will also aid in the establishment, growth and survival of the emerging grasses. Rates indicated under this submittal are for purposes of establishing a reasonable warranty for the operation (refer to Exhibit L — Reclamation Costs). WEED MANAGEMENT PLAN : Varra Companies, Inc. OMLR 112 Permit Application Parcel 122 — Resource Development Project 1 July 2015 Weed control at the site will utilize non-chemical means, unless, due to weed morphology, or other factors, circumstance require application of an approved herbicide. If chemical weed control is utilized, it will be conducted in compliance with manufacturer' s recommendations and in conformance with applicable federal, state, or local laws. Where possible, pre-emergent weed control chemicals will be utilized. Chemical application will be conducted or supervised by a qualified operator. Weed control will focus upon prevention, principally through the establishment of a diverse stabilizing cover of grasses, as described earlier. Regardless of control methodology, the intent of mechanical and chemical methods will be to prevent weed species from reproducing vegetatively, or by seed. In general, the idea is to aid the grasses in out competing weed species for plant available water and nutrients in the new soils, until such a time that the grasses are fully established over the applied areas, are dominant over the weeds, and capable of self regeneration. It should be understood that some weeds will remain. Total eradication of weeds is unlikely under the best circumstances, and is not a reasonable expectation or likely outcome. Varra Companies, Inc.

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

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil scientists classified and named the soils in the survey area, they compared the 6 Custom Soil Resource Report individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research, The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping , design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil- landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. 7 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map. Also presented are various metadata about data used to produce the map, and a description of each soil map unit. 8 Custom Soil Resource Report Soil Map b m c\I CO v in ul tO ° o 8 508100 506200 508300 508400 508500 508600 508700 I :': f1 508900 509000 �� 40° 11' 32" _ --- 40° 11132" o ` o 8 , t. o „^. o t. 0 o _ .-. v . \ -tt _ i a'S a f� ` . . _ , ;. - . . . -T..: .F7-. - ----wig . . i \ . _ -, v 4 , i v • , 1 .� . t7. i .._ `, § co 4 '• k ' -/I t p a • • 0 N (a Vie vo c � a� v ri • t 011..011.011..011. • �/ - I ti 1 V 11' I • /I v ! v it ;y. �_' t .1" -` .eV 1 �i • $ '. •.t f`�fh •r�._t 7 •_ 11 .. 1 I v I'�.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description . Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the 11 Custom Soil Resource Report contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion , and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha- Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 12 Custom Soil Resource Report Weld County, Colorado, Southern Part 1 —Altvan loam , 0 to 1 percent slopes Map Unit Setting Elevation: 4,500 to 4,900 feet Mean annual precipitation: 14 to 16 inches Mean annual air temperature: 46 to 48 degrees F Frost-free period: 130 to 150 days Map Unit Composition Altvan and similar soils: 90 percent Minor components: 10 percent Description of Altvan Setting Landform: Terraces Down-slope shape: Linear Across-slope shape: Linear Parent material: Old alluvium Properties and qualities Slope: 0 to 1 percent Depth to restrictive feature: More than 80 inches Drainage class: Well drained Capacity of the most limiting layer to transmit water (Ksat): Moderately high to high (0.20 to 2.00 in/hr) Depth to water table: More than 80 inches Frequency of flooding: None Frequency of ponding: None Calcium carbonate, maximum content: 5 percent Available water capacity: Low (about 5.7 inches) Interpretive groups Land capability classification (irrigated): 3s Land capability (nonirrigated): 4e Ecological site: Loamy Plains (R067BY002CO) Typical profile 0 to 10 inches: Loam 10 to 25 inches: Clay loam 25 to 60 inches: Gravelly sand Minor Components Cascajo Percent of map unit: 9 percent Aquic haplustolls Percent of map unit: 1 percent Landform: Swales 13 Custom Soil Resource Report 4—Aquolls and Aquepts, flooded Map Unit Setting Elevation: 3,600 to 4,700 feet Mean annual precipitation: 12 to 16 inches Mean annual air temperature: 50 to 55 degrees F Frost-free period: 100 to 165 days Map Unit Composition Aquolls and similar soils: 55 percent Aquepts, flooded, and similar soils: 25 percent Minor components: 20 percent Description of Aquolls Setting Landform: Drainageways, plains, depressions Down-slope shape: Linear Across-slope shape: Linear Parent material.

The Suitabilities and Limitations for Use section includes various soil interpretations displayed as thematic maps with a summary table for the soil map units in the selected area of interest. A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each interpretation. Vegetative Productivity Vegetative productivity includes estimates of potential vegetative production for a variety of land uses, including cropland, forestland, hayland, pastureland, horticulture and rangeland. in the underlying database, some states maintain crop yield data by individual map unit component. Other states maintain the data at the map unit level. Attributes are included for both, although only one or the other is likely to contain data for any given geographic area. For other land uses, productivity data is shown only at the map unit component level. Examples include potential crop yields under irrigated and nonirrigated conditions, forest productivity, forest site index, and total rangeland production under of normal, favorable and unfavorable conditions, Range Production ( Normal Year) Total range production is the amount of vegetation that can be expected to grow annually in a well managed area that is supporting the potential natural plant community. It includes all vegetation, whether or not it is palatable to grazing animals. It includes the current year's growth of leaves, twigs, and fruits of woody plants. It does not include the increase in stem diameter of trees and shrubs. It is expressed in pounds per acre of air-dry vegetation. In a normal year, growing conditions are about average. Yields are adjusted to a common percent of air-dry moisture content. In areas that have similar climate and topography, differences in the kind and amount of vegetation produced on rangeland are closely related to the kind of soil. Effective management is based on the relationship between the soils and vegetation and water. 26 Custom Soil Resource Report Map—Range Production (Normal Year) - o 0 N 'elm 0 7 O Q r 508100 508200 508300 508400 508500 508600 508700 508800 509900 509000 a 40° 11'32" Or, , r 40° 11'32" v i r ri 1 g vr a co i i • cn co' ----'L..

A map unit is typically composed of one or more "components". A component is either some type of soil or some nonsoil entity, e.g. , rock outcrop. For the attribute being aggregated, the first step of the aggregation process is to derive one attribute value for each of a map unit's components. From this set of component attributes, the next step of the aggregation process derives a single value that represents the map unit as a whole. Once a single value for each map unit is derived, a thematic map for soil map units can be rendered. Aggregation must be done because, on any soil map, map units are delineated but components are not. For each of a map unit's components, a corresponding percent composition is recorded. A percent composition of 60 indicates that the corresponding component 29 Custom Soil Resource Report typically makes up approximately 60% of the map unit. Percent composition is a critical factor in some, but not all, aggregation methods. The aggregation method "Weighted Average" computes a weighted average value for all components in the map unit. Percent composition is the weighting factor. The result returned by this aggregation method represents a weighted average value of the corresponding attribute throughout the map unit. Component Percent Cutoff: None Specified Components whose percent composition is below the cutoff value will not be considered. If no cutoff value is specified, all components in the database will be considered. The data for some contrasting soils of minor extent may not be in the database, and therefore are not considered. Tie-break Rule: Higher The tie-break rule indicates which value should be selected from a set of multiple candidate values, or which value should be selected in the event of a percent composition tie. Interpret Nulls as Zero: Yes This option indicates if a null value for a component should be converted to zero before aggregation occurs. This will be done only if a map unit has at least one component where this value is not null. 30 Custom Soil Resource Report Soil Properties and Qualities The Soil Properties and Qualities section includes various soil properties and qualities displayed as thematic maps with a summary table for the soil map units in the selected area of interest. A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each property or quality. Soil Physical Properties Soil Physical Properties are measured or inferred from direct observations in the field or laboratory. Examples of soil physical properties include percent clay, organic matter, saturated hydraulic conductivity, available water capacity, and bulk density. Bulk Density, One-Third Bar Bulk density, one-third bar, is the ovendry weight of the soil material less than 2 millimeters in size per unit volume of soil at water tension of 1 /3 bar, expressed in grams per cubic centimeter. Bulk density data are used to compute linear extensibility, shrink-swell potential, available water capacity, total pore space, and other soil properties. The moist bulk density of a soil indicates the pore space available for water and roots. Depending on soil texture, a bulk density of more than 1 .4 can restrict water storage and root penetration. Moist bulk density is influenced by texture, kind of clay, content of organic matter, and soil structure. For each soil layer, this attribute is actually recorded as three separate values in the database. A low value and a high value indicate the range of this attribute for the soil component. A "representative" value indicates the expected value of this attribute for the component. For this soil property, only the representative value is used. 31 Custom Soil Resource Report Map—Bulk Density, One-Third Bar b to N CO V- in to LO V Q O O Y r 0 508100 508200 508300 508400 508500 506600 508700 508800 508900 509000 $ 40° 11'32" m r 40° it 32" 8 S o tn NI- 4 v + e o CO CO 1 ' • efvlj Iiaill! 4 , g •: ih,--- I �' a • • • Q .1.• f1 i. ,` �.

If more than one component shares the highest percent composition, the corresponding "tie-break" rule determines which value should be returned. The "tie- break" rule indicates whether the lower or higher attribute value should be returned in the case of a percent composition tie. The result returned by this aggregation method may or may not represent the dominant condition throughout the map unit. Component Percent Cutoff: None Specified Components whose percent composition is below the cutoff value will not be considered. If no cutoff value is specified, all components in the database will be considered. The data for some contrasting soils of minor extent may not be in the database, and therefore are not considered. Tie-break Rule: Higher The tie-break rule indicates which value should be selected from a set of multiple candidate values, or which value should be selected in the event of a percent composition tie. Interpret Nulls as Zero: No This option indicates if a null value for a component should be converted to zero before aggregation occurs. This will be done only if a map unit has at least one component where this value is not null. Layer Options: All Layers For an attribute of a soil horizon, a depth qualification must be specified. In most cases it is probably most appropriate to specify a fixed depth range, either in centimeters or inches. The Bottom Depth must be greater than the Top Depth , and the Top Depth can be greater than zero. The choice of "inches" or "centimeters" only applies to the depth of soil to be evaluated. It has no influence on the units of measure the data are presented in. When "Surface Layer" is specified as the depth qualifier, only the surface layer or horizon is considered when deriving a value for a component, but keep in mind that the thickness of the surface layer varies from component to component. When "All Layers" is specified as the depth qualifier, all layers recorded for a component are considered when deriving the value for that component. Whenever more than one layer or horizon is considered when deriving a value for a component, and the attribute being aggregated is a numeric attribute, a weighted average value is returned, where the weighting factor is the layer or horizon thickness. 35 Custom Soil Resource Report Water Features Water Features include ponding frequency, flooding frequency, and depth to water table. Depth to Water Table "Water table" refers to a saturated zone in the soil. It occurs during specified months. Estimates of the upper limit are based mainly on observations of the water table at selected sites and on evidence of a saturated zone, namely grayish colors (redoximorphic features) in the soil. A saturated zone that lasts for less than a month is not considered a water table. This attribute is actually recorded as three separate values in the database. A low value and a high value indicate the range of this attribute for the soil component. A "representative" value indicates the expected value of this attribute for the component. For this soil property, only the representative value is used. 36 Custom Soil Resource Report Map--Depth to Water Table co N M v in La En o ° V v G O 0 508100 508200 508300 506400 506500 508600 508700 50©800 508900 509000 0 40° 11' 32" rn r-;- - 40° 11' 32" v � _ I r-.— 8 S I o 01 O ki O O co to ni � 1p r 1 I ..._. sef.visiamaisse 6 i v i 1 Ill v i �t CI co co _l_ _ N• 4 ' to . . ,. 4 P;.

A map unit is typically composed of one or more "components". A component is either some type of soil or some nonsoil entity, e.g. , rock outcrop. For the attribute being aggregated, the first step of the aggregation process is to derive one attribute value for each of a map unit's components. From this set of component attributes, the next step of the aggregation process derives a single value that represents the map unit as a whole. Once a single value for each map unit is derived, a thematic map for soil map units can be rendered. Aggregation must be done because, on any soil map, map units are delineated but components are not. For each of a map unit's components, a corresponding percent composition is recorded. A percent composition of 60 indicates that the corresponding component typically makes up approximately 60% of the map unit. Percent composition is a critical factor in some, but not all, aggregation methods. The aggregation method "Dominant Component" returns the attribute value associated with the component with the highest percent composition in the map unit. If more than one component shares the highest percent composition , the corresponding "tie-break" rule determines which value should be returned. The "tie- break" rule indicates whether the lower or higher attribute value should be returned in the case of a percent composition tie. The result returned by this aggregation method may or may not represent the dominant condition throughout the map unit. Component Percent Cutoff.

Tie-break Rule: Lower The tie-break rule indicates which value should be selected from a set of multiple candidate values, or which value should be selected in the event of a percent composition tie. Interpret Nulls as Zero: No This option indicates if a null value for a component should be converted to zero before aggregation occurs. This will be done only if a map unit has at least one component where this value is not null. Beginning Month: January Ending Month: December 40 Custom Soil Resource Report Flooding Frequency Class 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. Frequency is expressed as none, very rare, rare, occasional, frequent, and very frequent. "None" means that flooding is not probable. The chance of flooding is nearly 0 percent in any year. Flooding occurs less than once in 500 years. "Very rare" means that flooding is very unlikely but possible under extremely unusual weather conditions. The chance of flooding is less than 1 percent in any year. "Rare" means that flooding is unlikely but possible under unusual weather conditions. The chance of flooding is 1 to 5 percent in any year. "Occasional" means that flooding occurs infrequently under normal weather conditions. The chance of flooding is 5 to 50 percent in any year. "Frequent" means that flooding 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. "Very frequent" means that flooding 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. 41 Custom Soil Resource Report Map—Flooding Frequency Class N M V C7 47 to ° c zr o O 8 508100 508200 508300 508400 508500 `O8600 508700 508800 508900 509000 8 40° 11' 32" o1 r ♦ - -II . - ] T „T - - -- - a 40° 11'32" 1 -1 i 1 IO o i i _ 0 ' 0 O Cl r-- - r r_ - - en to 8 b .t • r c v v v _ - 0 1 o - - - - - ' - - - - - 0 v , co _ v ; V c.) - • OO _ ( ANN-•! o S 4, N ( . 1 1 -0 , o I _� o O ICO t 1 Illakh b • `-' - _ lfLI1r. .

Beginning Month: January Ending Month: December Ponding Frequency Class Ponding is standing water in a closed depression. The water is removed only by deep percolation, transpiration , or evaporation or by a combination of these processes. Ponding frequency classes are based on the number of times that ponding occurs over a given period. Frequency is expressed as none, rare, occasional, and frequent. "None" means that ponding is not probable. The chance of ponding is nearly 0 percent in any year. "Rare" means that ponding is unlikely but possible under unusual weather conditions. The chance of ponding is nearly 0 percent to 5 percent in any year. "Occasional" means that ponding occurs, on the average, once or less in 2 years. The chance of ponding is 5 to 50 percent in any year. "Frequent" means that ponding occurs, on the average, more than once in 2 years.

Beginning Month: January Ending Month: December 49 Custom Soil Resource Report Ecological Site Assessment Individual soil map unit components can be correlated to a particular ecological site. The Ecological Site Assessment section includes ecological site descriptions, plant growth curves, state and transition models, and selected National Plants database information. All Ecological Sites Rangeland An "ecological site" is the product of all the environmental factors responsible for its development. It has characteristic soils that have developed over time; a characteristic hydrology, particularly infiltration and runoff, that has developed over time; and a characteristic plant community (kind and amount of vegetation). The vegetation, soils, and hydrology are all interrelated. Each is influenced by the others and influences the development of the others. For example, the hydrology of the site is influenced by development of the soil and plant community. The plant community on an ecological site is typified by an association of species that differs from that of other ecological sites in the kind and/or proportion of species or in total production. An ecological site name provides a general description of a particular ecological site. For example, "Loamy Upland" is the name of a rangeland ecological site. An "ecological site ID" is the symbol assigned to a particular ecological site. The map identifies the dominant ecological site for each map unit, aggregated by dominant condition. Other ecological sites may occur within each map unit. Each map unit typically consists of one or more components (soils and/or miscellaneous areas). Each soil component is associated with an ecological site. Miscellaneous areas, such as rock outcrop, sand dunes, and badlands, have little or no soil material and support little or no vegetation and therefore are not linked to an ecological site. The table below the map lists all of the ecological sites for each map unit component in your area of interest. 50 Custom Soil Resource Report Map—Dominant Ecological Site N co to In n o r a 508100 508200 508300 508400 508500 506600 508700 508800 508900 509000 0 40° 11' 32" ot , _ 40° 11'32" I ex 1 o 1 _ . 0 v O t O CO I , -2 " - i • --,1 - I- ; . o r`'�► 4 i. , ,taro,i, .ail A.K.A._ - ...irme .�Y2{ p i �.. e 1 1111iiisl : v l •i G iE s 1 J4 ft r�� i �.

No aggregation of data has occurred as is done in reports in the Soil Properties and Qualities and Suitabilities and Limitations sections. The reports contain soil interpretive information as well as basic soil properties and qualities. A description of each report (table) is included. Land Classifications This folder contains a collection of tabular reports that present a variety of soil groupings. The reports (tables) include ail selected map units and components for each map unit. Land classifications are specified land use and management groupings that are assigned to soil areas because combinations of soil have similar behavior for specified practices. Most are based on soil properties and other factors that directly influence the specific use of the soil. Example classifications include ecological site classification, farmland classification, irrigated and nonirrigated land capability classification, and hydric rating. Hydric Soils This table lists the map unit components that are rated as hydric soils in the survey area. This list can help in planning land uses; however, onsite investigation is recommended to determine the hydric soils on a specific site (National Research Council, 1995; Hurt and others, 2002). The three essential characteristics of wetlands are hydrophytic vegetation , hydric soils, and wetland hydrology (Cowardin and others, 1979; U.S. Army Corps of Engineers, 1987; National Research Council, 1995; Tiner, 1985). Criteria for all of the characteristics must be met for areas to be identified as wetlands. Undrained hydric soils that have natural vegetation should support a dominant population of ecological wetland plant species. Hydric soils that have been converted to other uses should be capable of being restored to wetlands. Hydric soils are defined by the National Technical Committee for Hydric Soils (NTCHS) as soils that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part (Federal Register, 1994). These soils, under natural conditions, are either saturated or inundated long enough during the growing season to support the growth and reproduction of hydrophytic vegetation. The NTCHS definition identifies general soil properties that are associated with wetness. In order to determine whether a specific soil is a hydric soil or nonhydric soil, however, more specific information, such as information about the depth and duration of the water table, is needed. Thus, criteria that identify those estimated soil properties unique to hydric soils have been established (Federal Register, 2002). These criteria are used to identify map unit components that normally are associated with wetlands. The criteria used are selected estimated soil properties that are described in "Soil 55 Custom Soil Resource Report Taxonomy" (Soil Survey Staff, 1999) and "Keys to Soil Taxonomy" (Soil Survey Staff, 2006) and in the "Soil Survey Manual" (Soil Survey Division Staff, 1993). If soils are wet enough for a long enough period of time to be considered hydric, they should exhibit certain properties that can be easily observed in the field. These visible properties are indicators of hydric soils. The indicators used to make onsite determinations of hydric soils are specified in "Field Indicators of Hydric Soils in the United States" (Hurt and Vasilas, 2006). Hydric soils are identified by examining and describing the soil to a depth of about 20 inches. This depth may be greater if determination of an appropriate indicator so requires. It is always recommended that soils be excavated and described to the depth necessary for an understanding of the redoximorphic processes. Then , using the completed soil descriptions, soil scientists can compare the soil features required by each indicator and specify which indicators have been matched with the conditions observed in the soil. The soil can be identified as a hydric soil if at least one of the approved indicators is present. Map units that are dominantly made up of hydric soils may have small areas, or inclusions, of nonhydric soils in the higher positions on the landform, and map units dominantly made up of nonhydric soils may have inclusions of hydric soils in the lower positions on the landform. The criteria for hydric soils are represented by codes in the table (for example, 2B3). Definitions for the codes are as follows: 1 . All Histels except for Folistels, and Histosols except for Folists. 2. Soils in Aquic suborders, great groups, or subgroups, Albolls suborder, Historthels great group, Histoturbels great group, or Andic, Cumulic, Pachic, or Vitrandic subgroups that: A. are somewhat poorly drained and have a water table at the surface (0.0 feet) during the growing season, or B. are poorly drained or very poorly drained and have either: i. a water table at the surface (0.0 feet) during the growing season if textures are coarse sand, sand , or fine sand in all layers within a depth of 20 inches, or ii, a water table at a depth of 0.5 foot or less during the growing season if saturated hydraulic conductivity (Ksat) is equal to or greater than 6. 0 in/ hr in all layers within a depth of 20 inches, or iii. a water table at a depth of 1 .0 foot or less during the growing season if saturated hydraulic conductivity (Ksat) is less than 6.0 in/hr in any layer within a depth of 20 inches. 3. Soils that are frequently ponded for long or very long duration during the growing season. 4. Soils that are frequently flooded for long or very long duration during the growing season.

This classification shows, in a general way, the suitability of soils for most kinds of field crops (United States Department of Agriculture, Soil Conservation Service, 1961 ). Crops that require special management are excluded. The soils are grouped according to their limitations for field crops, the risk of damage if they are used for crops, and the way they respond to management. The criteria used in grouping the soils do not include major and generally expensive landforming that would change slope, depth , or other characteristics of the soils, nor do they include possible but unlikely major reclamation projects. Capability classification is not a substitute for interpretations designed to show suitability and limitations of groups of soils for rangeland, for forestland, or for engineering purposes. In the capability system, soils are generally grouped at three levels: capability class, subclass, and unit. 57 Custom Soil Resource Report Capability classes, the broadest groups, are designated by the numbers 1 through 8. The numbers indicate progressively greater limitations and narrower choices for practical use. The classes are defined as follows: - Class 1 soils have slight limitations that restrict their use. - Class 2 soils have moderate limitations that restrict the choice of plants or that require moderate conservation practices. - Class 3 soils have severe limitations that restrict the choice of plants or that require special conservation practices, or both. - Class 4 soils have very severe limitations that restrict the choice of plants or that require very careful management, or both. Class 5 soils are subject to little or no erosion but have other limitations, impractical to remove, that restrict their use mainly to pasture, rangeland, forestland, or wildlife habitat. - Class 6 soils have severe limitations that make them generally unsuitable for cultivation and that restrict their use mainly to pasture, rangeland, forestland, or wildlife habitat. - Class 7 soils have very severe limitations that make them unsuitable for cultivation and that restrict their use mainly to grazing, forestland, or wildlife habitat. - Class 8 soils and miscellaneous areas have limitations that preclude commercial plant production and that restrict their use to recreational purposes, wildlife habitat, watershed, or esthetic purposes. Capability subclasses are soil groups within one class. They are designated by adding a small letter, e, w, s, or c, to the class numeral, for example; 2e. The letter e shows that the main hazard is the risk of erosion unless close-growing plant cover is maintained; w shows that water in or on the soil interferes with plant growth or cultivation (in some soils the wetness can be partly corrected by artificial drainage); s shows that the soil is limited mainly because it is shallow, droughty, or stony; and c, used in only some parts of the United States, shows that the chief limitation is climate that is very cold or very dry_ In class 1 there are no subclasses because the soils of this class have few limitations. Class 5 contains only the subclasses indicated by w, s, or c because the soils in class 5 are subject to little or no erosion.

Important farmlands consist of prime farmland, unique farmland, and farmland of statewide or local importance. This list does not constitute a recommendation for a particular land use. In an effort to identify the extent and location of important farmlands, the Natural Resources Conservation Service, in cooperation with other interested Federal, State, and local government organizations, has inventoried land that can be used for the production of the Nation's food supply. Prime farmland is of major importance in meeting the Nation's short- and long-range needs for food and fiber. Because the supply of high-quality farmland is limited, the U.S. Department of Agriculture recognizes that responsible levels of government, as well as individuals, should encourage and facilitate the wise use of our Nation's prime farmland. Prime farmland, as defined by the U.S. Department of Agriculture, is land that has the best combination of physical and chemical characteristics for producing food, feed, forage, fiber, and oilseed crops and is available for these uses. It could be cultivated 59 Custom Soil Resource Report land, pastureland, forestland, or other land, but it is not urban or built-up land or water areas. The soil quality, growing season, and moisture supply are those needed for the soil to economically produce sustained high yields of crops when proper management, including water management, and acceptable farming methods are applied. In general, prime farmland has an adequate and dependable supply of moisture from precipitation or irrigation, a favorable temperature and growing season, acceptable acidity or alkalinity, an acceptable salt and sodium content, and few or no rocks. The water supply is dependable and of adequate quality. Prime farmland is permeable to water and air. It is not excessively erodible or saturated with water for tong periods, and it either is not frequently flooded during the growing season or is protected from flooding. Slope ranges mainly from 0 to 6 percent. More detailed information about the criteria for prime farmland is available at the local office of the Natural Resources Conservation Service. For some of the soils identified in the table as prime farmland, measures that overcome a hazard or limitation, such as flooding, wetness, and droughtiness, are needed. Onsite evaluation is needed to determine whether or not the hazard or limitation has been overcome by corrective measures. A recent trend in land use in some areas has been the loss of some prime farmland to industrial and urban uses. The loss of prime farmland to other uses puts pressure on marginal lands, which generally are more erodible, droughty, and less productive and cannot be easily cultivated. Unique farmland is land other than prime farmland that is used for the production of specific high-value food and fiber crops, such as citrus, tree nuts, olives, cranberries, and other fruits and vegetables. It has the special combination of soil quality, growing season, moisture supply, temperature, humidity, air drainage, elevation, and aspect needed for the soil to economically produce sustainable high yields of these crops when properly managed. The water supply is dependable and of adequate quality. Nearness to markets is an additional consideration. Unique farmland is not based on national criteria. It commonly is in areas where there is a special microclimate, such as the wine country in California. In some areas, land that does not meet the criteria for prime or unique farmland is considered to be farmland of statewide importance for the production of food, feed, fiber, forage, and oilseed crops. The criteria for defining and delineating farmland of statewide importance are determined by the appropriate State agencies. Generally, this land includes areas of soils that nearly meet the requirements for prime farmland and that economically produce high yields of crops when treated and managed according to acceptable farming methods. Some areas may produce as high a yield as prime farmland if conditions are favorable. Farmland of statewide importance may include tracts of land that have been designated for agriculture by State law, In some areas that are not identified as having national or statewide importance, land is considered to be farmland of local importance for the production of food, feed, fiber, forage, and oilseed crops. This farmland is identified by the appropriate local agencies. Farmland of local importance may include tracts of land that have been designated for agriculture by local ordinance.

The reports (tables) include all selected map units and components for each map unit, limiting features and interpretive ratings. Sanitary facilities interpretations are tools designed to guide the user in site selection for the safe disposal of sewage and solid waste. Example interpretations include septic tank absorption fields, sewage lagoons, and sanitary landfills. Sewage Disposal This table shows the degree and kind of soil limitations that affect septic tank absorption fields and sewage lagoons. The ratings are both verbal and numerical. Rating class terms indicate the extent to which the soils are limited by all of the soil features that affect these uses. Not limited indicates that the soil has features that are very favorable for the specified use. Good performance and very low maintenance can be expected. Somewhat limited indicates that the soil has features that are moderately favorable for the specified use. The limitations can be overcome or minimized by special planning, design, or installation. Fair performance and moderate maintenance can be expected. Very limited indicates that the soil has one or more features that are unfavorable for the specified use. The limitations generally cannot be overcome without major soil reclamation, special design, or expensive installation procedures. Poor performance and high maintenance can be expected. Numerical ratings in the table indicate the severity of individual limitations. The ratings are shown as decimal fractions ranging from 0.01 to 1 .00. They indicate gradations between the point at which a soil feature has the greatest negative impact on the use ( 1 . 00) and the point at which the soil feature is not a limitation (0.00). 61 Custom Soil Resource Report Septic tank absorption fields are areas in which effluent from a septic tank is distributed into the soil through subsurface tiles or perforated pipe. Only that part of the soil between depths of 24 and 72 inches or between a depth of 24 inches and a restrictive layer is evaluated. The ratings are based on the soil properties that affect absorption of the effluent, construction and maintenance of the system, and public health. Saturated hydraulic conductivity (Ksat), depth to a water table, ponding, depth to bedrock or a cemented pan, and flooding affect absorption of the effluent. Stones and boulders, ice, and bedrock or a cemented pan interfere with installation. Subsidence interferes with installation and maintenance. Excessive slope may cause lateral seepage and surfacing of the effluent in downslope areas. Some soils are underlain by loose sand and gravel or fractured bedrock at a depth of less than 4 feet below the distribution lines. In these soils the absorption field may not adequately filter the effluent, particularly when the system is new. As a result, the ground water may become contaminated. Sewage lagoons are shallow ponds constructed to hold sewage while aerobic bacteria decompose the solid and liquid wastes. Lagoons should have a nearly level floor surrounded by cut slopes or embankments of compacted soil. Nearly impervious soil material for the lagoon floor and sides is required to minimize seepage and contamination of ground water. Considered in the ratings are slope, saturated hydraulic conductivity (Ksat), depth to a water table, ponding, depth to bedrock or a cemented pan, flooding, large stones, and content of organic matter. Saturated hydraulic conductivity (Ksat) is a critical property affecting the suitability for sewage lagoons. Most porous soils eventually become sealed when they are used as sites for sewage lagoons. Until sealing occurs, however, the hazard of pollution is severe. Soils that have a Ksat rate of more than 14 micrometers per second are too porous for the proper functioning of sewage lagoons. In these soils, seepage of the effluent can result in contamination of the ground water. Ground-water contamination is also a hazard if fractured bedrock is within a depth of 40 inches, if the water table is high enough to raise the level of sewage in the lagoon, or if floodwater overtops the lagoon. A high content of organic matter is detrimental to proper functioning of the lagoon because it inhibits aerobic activity. Slope, bedrock, and cemented pans can cause construction problems, and large stones can hinder compaction of the lagoon floor. If the lagoon is to be uniformly deep throughout, the slope must be gentle enough and the soil material must be thick enough over bedrock or a cemented pan to make land smoothing practical. Information in this table is intended for land use planning, for evaluating land use alternatives, and for planning site investigations prior to design and construction. The information, however, has limitations. For example, estimates and other data generally apply only to that part of the soil between the surface and a depth of 5 to 7 feet. Because of the map scale, small areas of different soils may be included within the mapped areas of a specific soil. The information is not site specific and does not eliminate the need for onsite investigation of the soils or for testing and analysis by personnel experienced in the design and construction of engineering works. Government ordinances and regulations that restrict certain land uses or impose specific design criteria were not considered in preparing the information in this table. Local ordinances and regulations should be considered in planning , in site selection, and in design. 62 Custom Soil Resource Report Report--Sewage Disposal [Onsite investigation may be needed to validate the interpretations in this table and to confirm the identity of the soil on a given site.

These estimates are given for the layers of each soil in the survey area. 64 Custom Soil Resource Report The estimates are based on field observations and on test data for these and similar soils. Depth to the upper and lower boundaries of each layer is indicated. Cation-exchange capacity is the total amount of extractable cations that can be held by the soil, expressed in terms of milliequivalents per 100 grams of soil at neutrality (pH 7.0) or at some other stated pH value. Soils having a low cation-exchange capacity hold fewer cations and may require more frequent applications of fertilizer than soils having a high cation-exchange capacity. The ability to retain cations reduces the hazard of ground-water pollution. Effective cation-exchange capacity refers to the sum of extractable cations plus aluminum expressed in terms of milliequivalents per 100 grams of soil. It is determined for soils that have pH of less than 5. 5. Soil reaction is a measure of acidity or alkalinity. It is important in selecting crops and other plants, in evaluating soil amendments for fertility and stabilization, and in determining the risk of corrosion. Calcium carbonate equivalent is the percent of carbonates, by weight, in the fraction of the soil less than 2 millimeters in size. The availability of plant nutrients is influenced by the amount of carbonates in the soil. Gypsum is expressed as a percent, by weight, of hydrated calcium sulfates in the fraction of the soil less than 20 millimeters in size. Gypsum is partially soluble in water. Soils that have a high content of gypsum may collapse if the gypsum is removed by percolating water. Salinity is a measure of soluble salts in the soil at saturation. It is expressed as the electrical conductivity of the saturation extract, in millimhos per centimeter at 25 degrees C. Estimates are based on field and laboratory measurements at representative sites of nonirrigated soils. The salinity of irrigated soils is affected by the quality of the irrigation water and by the frequency of water application. Hence, the salinity of soils in individual fields can differ greatly from the value given in the table. Salinity affects the suitability of a soil for crop production, the stability of soil if used as construction material, and the potential of the soil to corrode metal and concrete. Sodium adsorption ratio (SAR) is a measure of the amount of sodium (Na) relative to calcium (Ca) and magnesium (Mg) in the water extract from saturated soil paste. It is the ratio of the Na concentration divided by the square root of one-half of the Ca + Mg concentration. Soils that have SAR values of 13 or more may be characterized by an increased dispersion of organic matter and clay particles, reduced saturated hydraulic conductivity and aeration, and a general degradation of soil structure. 65 E ' o . o a O en o u) u9 Ln 0 U) o (0 0 0 0 o 0 0 0 , r" O O O O i 0 P y E To' -c 0 O 0 O to E co co co , co O O Ed d c7 ; d d A 0 0 0 00 00 00 ad 0 o 0 0 0 0 0 1 3 1 S. a O 1- I O o o o O O 0 1 O o O O O co O It a E2) c 3 c d v O to a I o in0 O 0 ' -- o un O U) U) to a o r' o d d ! a o ch a d d 6j6 rt o v° I I . a.

The reports (tables) include all selected map units and components for each map unit. Soil physical properties are measured or inferred from direct observations in the field or laboratory. Examples of soil physical properties include percent day, organic matter, saturated hydraulic conductivity, available water capacity, and bulk density. Engineering Properties This table gives the engineering classifications and the range of engineering properties for the layers of each soil in the survey area. 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. 69 Custom Soil Resource Report 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 .

Custom Soil Resource Report Particle Size and Coarse Fragments This table shows estimates of particle size distribution and coarse fragment content of each soil in the survey area. The estimates are based on field observations and on test data for these and similar soils. Depth to the upper and lower boundaries of each layer is indicated. Particle size is the effective diameter of a soil particle as measured by sedimentation, sieving, or micrometric methods. Particle sizes are expressed as classes with specific effective diameter class limits. The broad classes are sand, silt, and clay, ranging from the larger to the smaller. Sand as a soil separate consists of mineral soil particles that are 0.05 millimeter to 2 millimeters in diameter. In this table, the estimated sand content of each soil layer is given as a percentage, by weight, of the soil material that is less than 2 millimeters in diameter. Silt as a soil separate consists of mineral soil particles that are 0. 002 to 0. 05 millimeter in diameter. In this table, the estimated silt content of each soil layer is given as a percentage, by weight, of the soil material that is less than 2 millimeters in diameter. Clay as a soil separate consists of mineral soil particles that are less than 0.002 millimeter in diameter. In this table, the estimated clay content of each soil layer is given as a percentage, by weight, of the soil material that is less than 2 millimeters in diameter. The content of sand, silt, and clay affects the physical behavior of a soil. Particle size is important for engineering and agronomic interpretations, for determination of soil hydrologic qualities, and for soil classification. The amount and kind of clay affect the fertility and physical condition of the soil and the ability of the soil to adsorb cations and to retain moisture. They influence shrink- swell potential, saturated hydraulic conductivity (Ksat), plasticity, the ease of soil dispersion, and other soil properties. The amount and kind of clay in a soil also affect tillage and earthmoving operations. Total fragments is the content of fragments of rock and other materials larger than 2 millimeters in diameter on volumetric basis of the whole soil. Fragments 2-74 mm refers to the content of coarse fragments in the 2 to 74 millimeter size fraction. Fragments 75-249 mm refers to the content of coarse fragments in teh 75 to 249 millimeter size fraction . Fragments 250-599 mm refers to the content of coarse fragments in the 250 to 599 millimeter size fraction. Fragments >=600 mm refers to the content of coarse fragments in the greater than or equal to 600 millimeter size fraction.

Clay as a soil separate consists of mineral soil particles that are less than 0. 002 millimeter in diameter. in this table, the estimated clay content of each soil layer is given as a percentage, by weight, of the soil material that is less than 2 millimeters in diameter. The content of sand, silt, and clay affects the physical behavior of a soil. Particle size is important for engineering and agronomic interpretations, for determination of soil hydrologic qualities, and for soil classification. The amount and kind of clay affect the fertility and physical condition of the soil and the ability of the soil to adsorb cations and to retain moisture. They influence shrink- swell potential, saturated hydraulic conductivity (Ksat), plasticity, the ease of soil dispersion, and other soil properties. The amount and kind of clay in a soil also affect tillage and earthmoving operations. Moist bulk density is the weight of soil (ovendry) per unit volume. Volume is measured when the soil is at field moisture capacity, that is, the moisture content at 1/3- or 1 /10- bar (33kPa or 10kPa) moisture tension. Weight is determined after the soil is dried at 105 degrees C. In the table, the estimated moist bulk density of each soil horizon is expressed in grams per cubic centimeter of soil material that is less than 2 millimeters in diameter. Bulk density data are used to compute linear extensibility, shrink-swell potential, available water capacity, total pore space, and other soil properties. The moist bulk density of a soil indicates the pore space available for water and roots. Depending on soil texture, a bulk density of more than 1 .4 can restrict water storage and root penetration. Moist bulk density is influenced by texture, kind of clay, content of organic matter, and soil structure. Saturated hydraulic conductivity (Ksat) refers to the ease with which pores in a saturated soil transmit water. The estimates in the table are expressed in terms of micrometers per second. They are based on soil characteristics observed in the field, particularly structure, porosity, and texture. Saturated hydraulic conductivity (Ksat) is considered in the design of soil drainage systems and septic tank absorption fields. 78 Custom Soil Resource Report Available water capacity refers to the quantity of water that the soil is capable of storing for use by plants. The capacity for water storage is given in inches of water per inch of soil for each soil layer. The capacity varies, depending on soil properties that affect retention of water. The most important properties are the content of organic matter, soil texture, bulk density, and soil structure. Available water capacity is an important factor in the choice of plants or crops to be grown and in the design and management of irrigation systems. Available water capacity is not an estimate of the quantity of water actually available to plants at any given time. Linear extensibility refers to the change in length of an unconfined clod as moisture content is decreased from a moist to a dry state. It is an expression of the volume change between the water content of the clod at 1 /3- or 1/10-bar tension (33kPa or 10kPa tension) and oven dryness. The volume change is reported in the table as percent change for the whole soil. The amount and type of clay minerals in the soil influence volume change. Linear extensibility is used to determine the shrink-swell potential of soils. The shrink- swell potential is low if the soil has a linear extensibility of less than 3 percent; moderate if 3 to 6 percent; high if 6 to 9 percent; and very high if more than 9 percent. if the linear extensibility is more than 3, shrinking and swelling can cause damage to buildings, roads, and other structures and to plant roots. Special design commonly is needed. Organic matter is the plant and animal residue in the soil at various stages of decomposition . In this table, the estimated content of organic matter is expressed as a percentage, by weight, of the soil material that is less than 2 millimeters in diameter, The content of organic matter in a soil can be maintained by returning crop residue to the soil. Organic matter has a positive effect on available water capacity, water infiltration, soil organism activity, and tilth. it is a source of nitrogen and other nutrients for crops and soil organisms. Erosion factors are shown in the table as the K factor (Kw and Kf) and the T factor. Erosion factor K indicates the susceptibility of a soil to sheet and rill erosion by water. Factor K is one of six factors used in the Universal Soil Loss Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE) to predict the average annual rate of soil loss by sheet and rill erosion in tons per acre per year. The estimates are based primarily on percentage of silt, sand, and organic matter and on soil structure and Ksat. Values of K range from 0. 02 to 0.69. Other factors being equal, the higher the value, the more susceptible the soil is to sheet and rill erosion by water. Erosion factor Kw indicates the erodibility of the whole soil. The estimates are modified by the presence of rock fragments. Erosion factor Kf indicates the erodibility of the fine-earth fraction, or the material less than 2 millimeters in size. Erosion factor T is an estimate of the maximum average annual rate of soil erosion by wind and/or water that can occur without affecting crop productivity over a sustained period. The rate is in tons per acre per year. Wind erodibility groups are made up of soils that have similar properties affecting their susceptibility to wind erosion in cultivated areas. The soils assigned to group 1 are the most susceptible to wind erosion, and those assigned to group 8 are the least susceptible. The groups are described in the "National Soil Survey Handbook." Wind erodibility index is a numerical value indicating the susceptibility of soil to wind erosion , or the tons per acre per year that can be expected to be lost to wind erosion. 79 Custom Soil Resource Report There is a close correlation between wind erosion and the texture of the surface layer, the size and durability of surface clods, rock fragments, organic matter, and a calcareous reaction. Soil moisture and frozen soil layers also influence wind erosion. Reference: United States Department of Agriculture, Natural Resources Conservation Service.

The reports (tables) include all selected map units and components for each map unit. Vegetative productivity includes estimates of potential vegetative production for a variety of land uses, including cropland, forestland, hayland, pastureland, horticulture and rangeland. In the underlying database, some states maintain crop yield data by individual map unit component. Other states maintain the data at the map unit level. Attributes are included for both, although only one or the other is likely to contain data for any given geographic area. For other land uses, productivity data is shown only at the map unit component level. Examples include potential crop yields under irrigated and nonirrigated conditions, forest productivity, forest site index, and total rangeland production under of normal, favorable and unfavorable conditions. Rangeland and Forest Vegetation Classification , Productivity, and Plant Composition In areas that have similar climate and topography, differences in the kind and amount of rangeland or forest understory vegetation are closely related to the kind of soil. Effective management is based on the relationship between the soils and vegetation and water. This table shows, for each soil that supports vegetation, the ecological site, plant association, or habitat type; the total annual production of vegetation in favorable, normal, and unfavorable years; the characteristic vegetation; and the average percentage of each species. An explanation of the column headings in the table follows. An ecological site, plant association, or habitat type is the product of all the environmental factors responsible for its development. It has characteristic soils that have developed over time throughout the soil development process; a characteristic hydrology, particularly infiltration and runoff that has developed over time; and a characteristic plant community (kind and amount of vegetation). The hydrology of the site is influenced by development of the soil and plant community. The vegetation, soils, and hydrology are all interrelated. Each is influenced by the others and influences the development of the others. The plant community on an ecological site, plant association, or habitat type is typified by an association of species that differs from that of other ecological sites, plant associations, or habitat types in the kind and/ or proportion of species or in total production. Descriptions of ecological sites are provided in the Field Office Technical Guide, which is available in local offices of the Natural Resources Conservation Service (MRCS). Descriptions of plant associations or habitat types are available from local U.S. Forest Service offices. Total thy-weight production is the amount of vegetation that can be expected to grow annually in a well managed area that is supporting the potential natural plant community. It includes all vegetation , whether or not it is palatable to grazing animals. It includes the current year's growth of leaves, twigs, and fruits of woody plants. It does not include the increase in stem diameter of trees and shrubs. It is expressed in pounds per acre of air-dry vegetation for favorable, normal, and unfavorable years. In a favorable year, the amount and distribution of precipitation and the temperatures make growing conditions substantially better than average. In a normal year, growing 84 Custom Soil Resource Report conditions are about average. In an unfavorable year, growing conditions are well below average, generally because of low available soil moisture. Yields are adjusted to a common percent of air-dry moisture content-. Characteristic vegetation (the grasses, forbs, shrubs, and understory trees that make up most of the potential natural plant community on each soil) is listed by common name. Under rangeland composition and forest understory, the expected percentage of the total annual production is given for each species making up the characteristic vegetation. The percentages are by dry weight for rangeland. Percentages for forest understory are by either dry weight or canopy cover. The amount that can be used as forage depends on the kinds of grazing animals and on the grazing season. Range management requires knowledge of the kinds of soil and of the potential natural plant community. It also requires an evaluation of the present range similarity index and rangeland trend. Range similarity index is determined by comparing the present plant community with the potential natural plant community on a particular rangeland ecological site. The more closely the existing community resembles the potential community, the higher the range similarity index. Rangeland trend is defined as the direction of change in an existing plant community relative to the potential natural plant community. Further information about the range similarity index and rangeland trend is available in the "National Range and Pasture Handbook," which is available in local offices of NRCS or on the Internet. The objective in range management is to control grazing so that the plants growing on a site are about the same in kind and amount as the potential natural plant community for that site. Such management generally results in the optimum production of vegetation, control of undesirable brush species, conservation of water, and control of erosion. Sometimes, however, an area with a range similarity index somewhat below the potential meets grazing needs, provides wildlife habitat, and protects soil and water resources.

The following assumptions of are based upon the pre-disturbed state of the application for purposes of determining estimated costs of reclamation and correlated financial warranty. Where appropriate, information is generalized and approximated from similar estimates determined by the Colorado Office of Mined Land Reclamation (OMLR), as indicated : Varra Companies, Inc. Varra-Coulson Resource Project 1 OMLR 112 Permit Application 1 July 2015 Exhibit L — Reclamation Costs Summary of Reclamation Costs: $ 3 ,656.00± Total Site Discharge — Avg.

RECLAMATION EXPOSURE: Based upon the Mining and Reclamation Plans of this application, the status and trend of activities and affected land; and related calculations to estimate reclamation liability, are determined as follows. Please Note : Due to the difficulty of calculating heavy equipment costs similar to the Division's software program, unit costs from previous and reasonably current Division estimates of like or similar kind have been utilized to create a reasonably close estimate. The per unit basis from Division records are shown along with other sources used or referenced to determine unit costs, at the back of this exhibit. DEWATERING: Until otherwise indicated , extraction will commence first in Tract A and be completed there before opening extraction of Tract B. The estimate is tied to the initial seven years of operations in Tract A. Two previous methods of determination are utilized, combined , and averaged as the final estimate, as follows: Initial Determinations: Correcting the volume by a difference in the surface area of the basin of Tract A with the surface elevation area of the anticipated static water level of the resulting reservoir of 8 percent = 2,742,391 .58± cu.yds = 553,891 ,868.21 gallons total anticipated water volume for Tract A. Assuming the life of the mine runs to the minimum term of extraction, or 25 years, the rate of extraction over the current combined extraction limits area of 101 .97± acres is slightly more than 4. 0± acres of extraction per year, or nearly 13. 8± years to complete the full extraction of Tract A. Therefore, approximately 7 years would pass to extract half the area of extraction of Tract A. In the event of default, pumps could be maintained or restarted, and anticipate only half the volume of half the extracted area of Tract A have occurred , then the total gallons of Tract A Varra Companies, Inc. Varra-Coulson Resource Project 2 OMLR 112 Permit Application 1 July 2015 Exhibit L — Reclamation Costs divided by 4 = 138,472,967.05 gallons to dewater in default at the end of 7 years of extraction.

NOTE: The basins resulting from extraction may be reclaimed in an unlined state, since the operator retains sufficient water resources to do so. The basins may be lined or otherwise segregated from the area groundwater as an option to the approved permit, in order to liberate the water otherwise retained to supplement loss from evaporation in the unlined state. Since sufficient water resources exist, the option to line the resulting basins at an unspecified time during the life of the permit is retained under this application and as part of the approved permit. GRADING : As stated in Exhibit D — Extraction Plan : A 1600± linear foot standard morphing extraction front is comprised of a 1 . 25H : 1V face along an approximate 800-1200± linear foot advancing; wall with trailing side slopes up to 400 total linear feet combined along either side of the advancing wall where it serves to define the predetermined boundary of the extraction limits shown on Exhibit C-2 : Extraction Plan Map. Concurrent grading follows immediately behind the trailing side slopes as they occur along the extraction limits. This morphing extraction front, with its advancing wall, trailing side slopes, and concurrent reclamation along the extraction limits is approximate for all active Tracts. The 1600± linear foot total extraction front is 'morphing' in that the total linear feet of the front will not exceed 1600± linear feet, however, the advancing wall and side slopes may deviate from the 'standard' lengths described above. For example : If the advancing wall is only 600± linear feet, trailing side slopes may have a combined length pending finished grading of up to 1,000± linear feet. Another example Varra Companies, Inc. Varra-Coulson Resource Project 4 OMLR 112 Permit Application 1 July 2015 Exhibit L -- Reclamation Costs is if the advancing wall is 1 ,400± linear feet long, there is only 200± linear feet of trailing wall, and operations must be more Johnny on the spot in keeping up with concurrency in this configuration. So the 'morphing' of the front generally affects the pace of concurrent reclamation of the trailing wall .

Soil Demand AND Re-soiling of Affected Lands (refer to Exhibit D) : NOTE : The soil demand (and related costs) will decrease proportionately as extraction activities progress over each Tract of planned extraction as a result of concurrent reclamation. For now, an area estimate to reclaim the lands above the static water level of Tract A and the 10.00± acres of the Processing/Mineral Reserve Area ( 1) will be determined for resoiling expenses.

Establishment of Vegetation over Affected Lands: The demand establishment of vegetation over the affected lands will also diminish proportionately with the planned extraction of the Tracts. For now, the total exposure is estimated as indicated above to be 15 . 57± acres under a default (refer to resoil area, above) : NOTE: The vegetation demand (and related costs) will decrease proportionately as extraction activities increase over each Tract of planned extraction . The cost for seed is shown on Exhibit L - Table L- 1 : Primary/Preferred Re-vegetation Seed Mixture and Costs. The mixture includes a substitute for mulch in the inclusion of a wheatgrass hybrid . The Division has historically agreed with and approved the inclusion of this hybrid as a substitute for mulch . These costs are as follows: $ 60. 53± Preferred Seed Mix x 15 .57± acres $ 942.45± Sub-Total Seed The cost for applying seed is based upon information derived in proximity to the Northern Colorado economy. Costs for tilling, fertilizing and seeding are based upon estimates from Longs Peak Equipment Co. These costs, including labor, are reflected as follows: $ 25. 00± per acre Tilling $ 20.00± per acre Fertilizing Varna Companies, Inc.

Assume a 50± percent failure and add half the expense back into the total for reseeding, or: $ 977.25± Sub-Total Re-seeding costs $ 2,931 .75± Total Re-vegetation Expense OTHER MISCELLANEOUS COSTS: Mobilization and demobilization costs are based upon the Division's estimates, which are pending. Demolition of Structures: None. Building Permits for structures will be obtain where required from the Weld County Building Department. Please Note: The per unit cost values derived from previous OMLR determinations for heavy equipment, as applied to this exhibit, are included at the back of this exhibit. Since there is no possibility of the applicant in fully reproducing the Division's methods, utilizing similarities from past OMLR calculations is the most viable and accurate means available for the applicant to derive reasonable estimates of per unit costs and should result in estimates very reliable with that of the Division.

Liability insurance The "General Conditions" section of most government construction contracts requires that the successful bidder obtain adequate public liability insurance. To account for this expense, DMG utilizes data from MEANS Site Work & Landscape Cost Data, Administrative Requirements Section - Project Management/Coordination -- Average public liability insurance - expressed as a percentage of job cost. EXAMPLE; In the 2006 edition of MEANS Site Work and Landscape Cost Data, the average public liability insurance expense is listed at 2. 02% of job cost. For a reclamation project With an estimated total direct cost of $ 100,000, the contractor's liability insurance expense will be $2020. 2. Performance bond Although the main objective of preparing a reclamation cost estimate is to determine the total amount of reclamation bondto be held by the regulatory authority, be aware , r"' that whenever a reclamation bond is actually forfeited and the agency contracts with a 'KJ construction company to perform the work, the General Conditions section of the contract usually requires that the contractor obtain a different type of bond known in the construction industry as a performance bond, The performance bond is essentially a guarantee by a bank or bonding company to the project owner (e.g . DMG) that all work will be completed in the event the contractor fails to perform per the terms of the contract. In some cases, a labor & materials payment bond may also be required. To account for this expense, DMG utilizes data from MEANS Site Work & Landscape Cost Data, Administrative Requirements Section - Project Management,/Coordination - Performance bond - expressed as a percentage of job cost. EXAMPLE; In the 2006 edition of MEANS Site Work and Landscape Cost Data, the average performance bond expense is listed at a minimum value of 0. 62% of job cost and a maximum value of 1.50%: This works out to an average value of 1 . 06% . For a reclamation project with an estimated total direct cost of $ 100,000, the contractor's performance bond expense will be $ 1/060. 3. Job superintendent State & Federal construction contracts often require that the contractor keep a job superintendent on site at all times work is being performed . For small projects 1: involving a simple sequence of tasks where each task can be performed by one piece of equipment, the equipment operator can sometimes double as job superintendent 4 P_\, 'WESTER STATESRECLAMATION INC: . ist? :t. 775 imperial street :t :F.rederfci{, Cbtor?drnS051+ :(:a03) $3^-1.9.8'.

Cattany 8120 Gage St. Division Director Frederick, CO 80516 Natural Resource Trustee Re: Kurtz Resource Recovery & Land Devlpmnt Proj, Permit No. M-1999-006, Financial Warranty Increase, Revision No. SI-1 Dear Mr. Varra: On November 20, 2009 the Division of Reclamation, Mining and Safety (Division) increased the current Financial Warranty for this permit. The previous Financial Warranty calculation of $2,486,383.00 has been revised to reflect the changes to the Mining and Reclamation Plans submitted under Technical Revision — 02. The Division's updated calculations (copy enclosed) estimate the cost to reclaim the site to be $286,979.00. This is an increase of $228,179.00 over the $58,800.00 currently held by the Division. Per our agreement, the Division will grant an additional 30 days beyond the approval date of Technical Revision — 02 to submit the increased Financial Warranty. The increase needs to be accepted prior to December 21, 2009. If you wish to submit a different type of Financial Warranty, you may fiend the appropriate forms on the Division's website at http://mining.state.co.us/Mineral%20Forms.htm. • If you have any questions, please contact me at (303) 866-3567 x8116.

(c) where such structure is a utility, the Applicant may supply a notarized letter, on utility letterhead , from the owner(s) of the utility that the mining and reclamation activities, as proposed , will have "no negative effect" on their utility. 6.5 GEOTECHNICAL STABILITY EXHIBIT 1 ) On a site-specific basis, an Applicant shall be required to provide a geotechnical evaluation of all geologic hazards that have the potential to affect any proposed impoundment, slope, embankment, highwall, or waste pile within the affected area. The Applicant may also be required to provide a geotechnical evaluation of all geologic hazards, within or in the vicinity of the affected lands, that may be de-stabilized or exacerbated by mining or reclamation activities. (2) On a site-specific basis, an Applicant shall be required to provide engineering stability analyses for proposed final reclaimed slopes, highwalls, waste piles and embankments. An Applicant may also be required to provide engineering stability analyses for certain slopes configuration as they will occur during operations, including , but not limited to embankments. Information for slope stability analyses may include, but would not be limited to, slope angles and configurations, compaction and density, physical characteristics of earthen materials, pore pressure information , slope height, post-placement use of site, and information on structures or facilities that could be adversely affected by slope failure. (3) Where there is the potential for off-site impacts due to failure of any geologic structure or constructed earthen facility, which may be caused by mining or reclamation activities, the Applicant shall demonstrate through appropriate geotechnical and stability analyses that off-site areas will be protected with appropriate factors of safety incorporated into the analysis. The minimum acceptable safety factors will be subject to approval by the Office, on a case by- case basis, depending upon the degree of certainty of soil or rock strength determinations utilized in the stability analysis, depending upon the consequences associated with a potential failure, and depending upon the potential for seismic activity at each site.

To assure the stability of any significant, valuable, and permanent man-made structures that may exist within 200± feet of planned extraction activities ; a complete stability analysis performed by AWES, Ft. Collins, Colorado , follows. The report verifies that the maximum planned extraction slopes of 1 . 25H: 1V along the extraction limit will not pose a hazard to those structures with the following caveat: Extraction will limit slopes along the extraction limits to be cut to 1 .25H : 1V from the surface to a depth of 20 feet, and thereafter 3H : 1V at a a depth of 39 feet. Where extracted depths are deeper than 39 feet, as long as 3I1 : 1V slopes are maintained from the extracted floor to a height of 20 feet, slopes above the 20 foot height of those 3H : 1V slopes may be 1 . 25H : 1V from that point to the surface , or where otherwise consistent with correlated percentage determined in the included AWES Stability Analysis report of 27 July 2015 . If additional information and analyses indicate that uniform 1 .25H: 1V slopes regardless of depth will not pose a hazard to structures 10± feet or greater from the extraction limits boundary, a correlated Technical Revision will be submitted for review and approval in advance prior to effecting such slopes. To the extent practical, operations will remain 125 .0± feet or greater from residential structures , not otherwise owned or controlled by the operator, or otherwise accommodated by the landowner by separate written agreement with the owner of the residential structure . Extraction will maintain a minimum 10± foot separation from any right- of-way, easement or structure , unless otherwise provided for by separate written agreement with the owner(s) of said right-of- way, easement, or structure. Concurrent grading and reclamation of completed areas of extraction will reduce extracted slopes to a minimum of 3H : 1V, or flatter, over a majority of the extraction area, in conformance with Rule 3 . 1 . 5(7) , unless otherwise provided for. Further, all extraction limit lines drawn closer than 10± feet of a structure , easement, or right- of-way are for purposes of representing the maximum possible reach if by agreement; otherwise, the written separation from all right- of-ways, easements, and structures is limited as to the extraction limits boundary described by this text and not the shown graphical line .

CC .SC iJA Introduction The following report presents the results of a slope stability analysis for a proposed open cut gravel extraction operations at the Varra Pitt 122 operations near Platteville, Colorado. This analysis was performed at the request of Varra Companies, Inc., (Varra). This report is being submitted in partial fulfillment of an OMLR 112 Mine Permit Application . Background Information The proposed gravel quarry is located in the NW1/4, S33, T3N, R67W of the 6tf, Principal Meridian. The surrounding land use consists of agricultural, rural residential, commercial and open-cut gravel quarry operations. The proposed mine area occupies an estimated 102 acres. The water table at the site is located in unconsolidated alluvial deposits with an averaage depth to water of approximately six feet below ground surface. Soil conditions generally consist of varying thicknesses of top soil underlain by sand and gravel deposits, which in turn are underlain by sandy and argillaceous siltstones. Over the entire area the average saturated thickness of the sand and gravel deposits (prior to mining) is estimated at about 35 feet. It is our understanding that the sand and gravel will be dewatered during aggregate extraction. The site location is presented on Figure 1. Previous Investigations Terracon Consultants, Inc., (Terracon) conducted a sand and gravel study in September 2008. The study consisted of drilling 22 soil borings from ground surface to bedrock to determine the potential aggregate mass within the proposed mine boundary. Selected sand and gravel samples were obtained for grain size distribution determinations. The depth to bedrock over the site varied between 13 and 55 feet below ground surface. The majority of the study area consists of three to five feet of clayey sand underlain by sand and gravel with occasional clayey sand, silty sand and sand lenses. Bedrock consists of sandstone, siltstone and claystone. The Terracon report is provided as Attachment A. Slope Stability Analysis Pit 122— Varra 112 Permit Application Weld County, Colorado Page 2 Overview of Stability Analyses The depth to bedrock varies between 13 and 55 feet across the study area with the bedrock surface dipping steeply to the northwest. Soil strength testing was not performed as part of the Terracon study and in the absence of strength test data the following soil strength parameters were used in the stability analysis. Table 1 — Soil Strength Properties Wet Unit Weight Saturated Unit Weight Cohesive Friction Material (lbs/cu ft.) (lbs/cu ft.) Intercept ( PSF) Angle Top Soil 114 126 50 28 Poorly Graded 117 130 0 31 Sand Sand & Gravel 130 137 0 37 Weathered 125 142 0 14 Bedrock Bedrock 125 143 50 28 The assumptions used in the bank stability analysis include the following: • The static depth to groundwater at the distance to no pumping influence is 6 feet below ground surface and the water table will intersect the pit bank just above the mine floor (seepage face) during steady state dewatering. • The pit depth will vary between 25 and 45 feet below grade. • Load surcharges of 2,500 pounds per square foot were simulated. • During extraction activities the pit bank slope will vary between 3H:1V and 1.25H:1V. The software package PC-STABL was used to evaluate slope stability. Simulations using Spencer, Modified Bishop and Modified Janbu methods were run to determine the most conservative Slope Stability Analysis Pit 122 — Varra 112 Permit Application Weld County, Colorado Page 3 safety factor. The soil strength properties used in the analysis are presented on computer generated data sheets which are presented in Attachment B. Stability analyses were ran for three scenarios — a 25 foot mine depth, a 35 foot mine depth and a 45 foot mine depth. A series of trial and error simulations were ran to determine the mine wall slopes that would meet a safety factor of 1.3 or greater. A review of Attachment B shows proposed bank profiles are stable with a calculated safety factors that vary between 1.3 and 1.6. Discussion Slope failure analyses for proposed open cut gravel operations at the Varra Pitt 122 site indicate proposed slope cuts will be stable for dewatered or static water table conditions. As the depth to bedrock varies greatly it is recommended that the lower half (modeled at 45%) of the mine slope be maintained at 3H : 1V and the remaining mine wall sloped at 1.25H : 1V. This allows for maximum material extraction while maintaining an adequate safety factor. If any significant modifications to proposed pit wall slopes occur this analysis may not be representative of site conditions and additional simulations are recommended.

The site is located at the southeast corner of the intersection of Weld County Road 17 and Weld County Road 28 in Weld County, Colorado. The purpose of these services is to provide information and preliminary geotechnical engineering recommendations relative to: • subsurface soil and bedrock conditions. • groundwater conditions. • feasibility for use of site as a gravel mining pit 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 structures, and our understanding of the proposed project. PROJECT INFORMATION Based on preliminary information provided by LaFarge, the proposed project will include the development of an approximate 168-acre parcel . Currently the site is being considered to be utilized as a sand and gravel mining operation pit. SITE EXPLORATION PROCEDURES The scope of the services performed for this project to date have included site reconnaissance by an geotechnical engineer, a subsurface exploration program , laboratory testing and preliminary engineering analysis. Field Exploration : A total of 22 test borings were drilled between September 3, 2008 to September 15, 2008 to depths of about 20 to 63 feet below existing site grade at the approximate locations shown on the Boring Location Diagram, Figure 1 . The borings were drilled across the site at approximate 500 foot grid spacings in order to asses the general subsurface conditions. Portions of the site were inaccessible at this time due to current 1 Preliminary Geotechnical Engineering Report and Sand/Gravel Study Terracon Proposed Sand/Gravel Mine- Weld County, Colorado Terracon Project No. 20085065 PRELIMINARY DRAFT SUbMVtITTAL agricultural operations. Borings in these locations will be drilled at a later date. The borings were advanced with a truck-mounted drilling rig , utilizing 4-1 /4-inch inside diameter (approx 8- inch outside diameter) hollow-stem, auger. The borings were located in the field by a hand held GPS . Elevations were estimated at each boring location by interpolation from contours indicated on topographic mapping provided by Northern Engineering . The accuracy of boring locations and elevations should only be assumed to the level implied by the methods used . Lithologic logs of each boring were recorded by an engineering geologist during the drilling operations. At selected intervals, samples of the subsurface materials were taken by driving split-spoon and ring barrel samplers. Representative bulk samples of subsurface materials were also obtained at approximate 5 to 10-foot intervals. Penetration resistance measurements were obtained by driving the split-spoon or ring barrel into the subsurface materials with a 140-pound hammer falling 30 inches. The penetration resistance value is a useful index to the consistency, relative density or hardness of the materials encountered . Groundwater measurements were made in each boring at the time of site exploration. A majority of the borings were backfilled after drilling operations due to safety considerations; therefore subsequent groundwater measurements were not obtained in these borings. 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 . Samples of bedrock were classified in accordance with the general notes for Rock Classification. At that time, an applicable laboratory testing program was formulated to determine gradation characteristics 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. These results were used for assessing the feasibility of utilizing the site as a sand/gravel pit and for the preliminary geotechnical engineering analyses. Laboratory tests were performed in general accordance with the applicable local or other accepted standards. 2 Preliminary Geotechnical Engineering Report and Sand/Gravel Study Terracon Proposed Sand/Gravel Mine- Weld County, Colorado Terracon Project No. 20085065 PRELIMINARY DRAFT SUBMITTAL SITE CONDITIONS The site was vacant and to our knowledge had not been previously developed and was used for agricultural purposes. The site was bounded on the north by County Road 28 and agricultural land beyond, and on the east, south and west by agricultural property. The ground surface was rowed/tilled and generally soft and moist due to the on-going agriculture and irrigation practices. Vegetation consisted of crops of corn . An existing single family residence and associated outbuildings was located at the approximate center of the site with access to the north to County Road 28. Site drainage was generally poor and in the form of surface sheet flow. Several areas of standing water were noted , particularly at the northeast corner of the site. Additionally, several underground petroleum lines and a tank installation is present on the site. SUBSURFACE CONDITIONS Geology: Surficial geologic conditions at the site, as mapped by the U . S. Geological Survey (USGS) (' Colton, 1978) , consist of the Piney Creek Alluvium of Quaternary Age. This material generally consists of sandy to gravely alluvium . These materials, as mapped in this area, are generally on the order of about 10 to 20 feet in thickness. Bedrock underlying the surface units consists of the Fox Hills Sandstone of Upper Cretaceous Age. This formation is generally comprised of silty siltstone interbedded with gray fissile shale. The thickness of this unit has been reported to be on the order of 300 to 500 feet. 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 present stream courses with stream deposits consisting of relatively clean and sound gravel . This is consistent with the materials encountered in our borings. Mapping performed by the USGS (3Rodger B. Colton, 1974) indicates that the site 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).

Grain size distribution by weight is mapped near the area as 3% clay and sift, 44% sand, 9% granular gravel, and 44% pebbles. The material contains few or no reactive constituents and is a source of quality gravel for the Longmont area. Gravel thicknesses of these deposits mapped in the area range from approximately 15 to 28 feet in thickness. Based on the materials encountered in our borings, it is likely that commercially extractable mineral deposits will be encountered 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 and Bedrock Conditions: As presented on the Logs of Borings, surface soils to depths of about 13 to 55 feet consist predominantly of overburden sands with gravels. Claystone, siltstone, and/or sandstone bedrock was encountered below the overburden sands and extended to the total depths of exploration of about 20 to 63 feet below existing site grade. A bedrock contour map has been generated based on preliminary information and is provided in Figure 2. Field and Laboratory Test Results: Field test results indicate the sand soils vary from loose to very dense in relative density. The bedrock varies from medium hard to hard in hardness. Gradations performed on the bulk samples obtained from the test borings indicate that the overburden materials generally classify as sands with the following characteristics: Boring Sample depth epBedroth to ck (ft) %gravel %sand %silt/clay No. _ B1 9-14 ft 53.5 0.4 84. 1 15.5 61 19-24 ft 53.5 10.2 81 .2 8.6 B1 29-34 ft 53. 5 12.4 75.6 12.0 B2 10-20 ft 55 21 .8 70.8 7A B2 40-50 ft 55 34. 1 54.6 _ 11 .3 B3 20-50 ft 50 32.3 59. 1 _ 8.6 B3 9-20 ft 50 25.9 55.8 18.3 B4 10-20 ft 47 3.9 66.4 29.7 B4 20-30 ft 47 8. 7 58. 1 _ 33.2 B4 40-47 ft 47 5.8 74.6 19.6 B5 0-10 ft 47 33.5 49.5 17.0 B5 10-20 ft 47 43.7 46.9 9.4 B5 20-30 ft 47 16.9 57.0 26. 1 B5 30-40 ft 47 17.0 73.8 9.2 B5 40-47 ft 47 9.4 80.7 9.9 4 Preliminary Geotechnical Engineering Report and Sand/Gravel Study Terracon Proposed Sand/Gravel Mine- Weld County, Colorado Terracon Project No. 20085065 PRELIMINARY DRAFT SUBMITTAL B6 20-30 ft 52 62.2 24.9 12.9 B6 _ 30-52 ft 52 30.6 59. 1 10.3 B8 0-10 ft 45 39.6 48.0 12.4 B8 10-30 ft 45 47.8 44.7 7.5 B10 10-30 ft 47 20.0 69.2 10.8 B10 40-47 ft 47 20.0 69.5 10.5 B11 20-30 ft _ 45 48.4 39.2 12.4 B11 30-45 ft 45 26.0 64.0 10.0 B13 0-10 ft 44 51 .2 43. 5 5. 3 B13 10-20 ft 44 26.8 69.4 3. 8 B13 20-30 ft 44 20.7 75. 3 4.0 B13 30-40 ft 44 27.3 68. 0 4.7 B16 10-20 ft 33 24.3 66.2 9.5 816 20-30 ft 33 26.4 67.2 6.4 B17 9-20 ft 38 27.4 61 .8 10.8 B17 20-30 ft 38 53.4 36. 1 10.5 B17 30-38 ft 38 40. 1 49.9 10.0 B19 0-10 ft 39 10.3 70. 1 19.6 B19 20-30 ft 39 20.6 67.5 11 .9 B21 0-10 ft 22 0.7 68.6 30.7 B21 20-30 ft 22 34.8 53.5 11 .7 B22 0-10 ft 37 0.2 40. 1 59.7 B22 10-20 ft 37 4. 1 77.4 18.5 B22 20-30 ft 37 4.2 64.9 30.9 B23 0-9 ft 45 0.9 68.0 31 . 1 B23 19-29 ft 45 17.7 53.4 28. 9 B23 29-39 ft 45 2.6 59.8 37.6 B23 39-44 ft 45 0.0 51 .4 48.6 824 10-20 ft 22 5.5 73. 7 20.8 B25 10-14 ft 15 1 .7 76.8 21 .5 B26 0-10 ft 23 0. 1 63.8 _ 36. 1 B26 10-20 ft 23 0. 1 75.4 24.5 B27 10-20 ft 35 39.3 50.8 9.9 B27 20-30 ft 35 42.5 50.6 6.9 B27 30-35 ft 35 38.4 53.9 7.7 B28 9-19 ft 43 0.0 78.7 21 .3 B28 19-29 ft 43 1 . 3 i 85.4 13.3 B28 29-39 ft 43 0.5 72. 7 26.8 B29 0-9 ft 13 3. 1 73.8 23. 1 Average 20.3 62.5 17.2 It should be noted that the gradations were performed primarily on bulk samples obtained from auger cuttings. Efforts were made to obtain a representative sampling of the subsurface materials at the depths indicated , however the depths of the samples and gradations presented 5 Preliminary Geotechnical Engineering Report and Sand/Gravel Study Terracon Proposed Sand/Gravel Mine- Weld County, Colorado Terracon Project No. 20085065 PRELIMINARY DRAFT SUBMITTAL should be considered approximate only. The gradation analysis curves are presented at the conclusion of the report. Groundwater Conditions: Groundwater was generally encountered at depths of about 3 to 10 feet (average of about 6 feet) below existing site grade in the test borings at the time of field exploration. Groundwater was encountered at a depth of about 40 at the southeast corner of the site. A groundwater contour map has been generated based on preliminary information and has been provided in Figure 3. A majority of the borings were backfilled after drilling due to cave-in conditions and safety considerations, therefore subsequent groundwater measurements were not obtained in these borings. These observations represent groundwater conditions at the time of the field exploration , and may not be indicative of other times or at other locations. Groundwater levels can be expected to fluctuate with varying seasonal and weather conditions. Based upon review of U .S . Geological Survey Maps, (4Hillier, 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 10 to 20 and greater than 20 feet below present ground surface. Fluctuations in groundwater levels can best be determined by implementation of a groundwater- monitoring plan . Such a plan would include installation of groundwater-monitoring wells and periodic measurement of groundwater levels over a sufficient period of time. The possibility of groundwater fluctuations should be considered when developing design and construction plans for the project. PRELIMINARY RECOMMENDATIONS The preliminary recommendations presented in this report are based on the assumption that the subsurface conditions do not deviate appreciably from those encountered in the borings. Supplementary geotechnical engineering exploration should be performed at the site upon completion of initial design studies. Supplemental geotechnical explorations will be used to confirm or modify the recommendations contained in this preliminary report. Sand/Gravel Mining and Geotechnical Considerations: Based upon the materials encountered during the preliminary geotechnical exploration of the site and the results of the laboratory testing , the site appears to be feasible for the purpose of mining various quantities of 'Hillier, Donald E. ; and Schneider, Paul A., Jr., 1979, Depth to Water Table (1976-1977) in the Boulder-Fort Collins- Greeley Area, Front Range Urban Corridor, Colorado, United States Geological Survey, Map 1-855-I. 6 Preliminary Geotechnical Engineering Report and Sand/Gravel Study Terracon Proposed Sand/Gravel Mine- Weld County, Colorado Terracon Project No. 20085065 PRELIMINARY DRAFT SUBMITTAL sand and gravel sized aggregate. However, the majority of the gravels are smaller than % - inches in diameter. The depth of the sand and gravel overburden is approximately 13 to 55 feet with the average depth about 39 feet below existing site grade. Relatively shallow bedrock was encountered at the site in Boring Nos. 25, 26, and 29 at depths of 15 to 23 feet. We recommend that LaFarge analyze the gradations provided herein carefully to determine the economic and physical viability of developing the site for mining . If the preliminary assessments look favorable for mining the site, we recommend that further exploration be performed with a reverse air circulation drill rig in order to collect additional sand and gravel samples since large samples of the subsurface materials are not practical with conventional hollow stem auger methods due to heaving sands and groundwater conditions. As previously outlined, groundwater was encountered across the site at depths ranging from about 3 to 10 feet below existing site grade. If deeper mining operations are being considered, dewatering of the site will likely be required and an experienced contractor should be consulted to assist with determining the feasibility of dewatering in such conditions. It has been our experience that slurry cut-off walls are effective for dewatering when the depth to bedrock is less than about 40 to 60 feet due to the practical installation depths of these systems. Slurry walls must typically be keyed-in to bedrock or other relatively impervious stratum in order to be effective. Therefore, the use of very large equipment may be required for slurry wall installations, based on the depth to bedrock at the site. Other dewatering alternatives for the purpose of mining would consist of installing well-points in specific areas that are being excavated. Other Geotechnical Considerations: Protection of the existing single family residence will require particular care during excavation and dewatering activities. Significant dewatering of the site will likely cause some settlement of the structure and associated outbuildings. Additional analysis will be required to determine the approximate magnitude of this settlement. Slope stability analyses will be required to determine the required slope inclinations required to maintain stability of the structure during mining operations. Other options for stabilizing the structure could include shoring systems. A thorough evaluation and documentation of the existing structure conditions is recommended prior to beginning any construction activities. GENERAL COMMENTS Supplemental exploration and analyses should be undertaken in order to develop final design parameters and to confirm and/or modify the preliminary recommendations and conclusions contained in this report. This report should not be relied upon for final design, and should only be used for planning and budget purposes. 7 Preliminary Geotechnical Engineering Report and Sand/Gravel Study Terracon Proposed Sand/Gravel Mine- Weld County, Colorado Terracon Project No. 20085065 PRELIMINARY DRAFT SUBMITTAL Terracon should be retained to review the final design plans and specifications so comments can be made regarding interpretation and implementation of our geotechnical recommendations in the design and specifications. Terracon should also be retained to provide testing and observation during the excavation, grading , foundation and construction phases of the project. The analysis and recommendations presented in this preliminary 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.

For 3" O.D. ring samplers (RS) the penetration value is reported as the number of blows required to advance the sampler 12 inches using a 140- pound hammer falling 30 inches, reported as "blows per foot," and is not considered equivalent to the "Standard Penetration" or "N- value". WATER LEVEL MEASUREMENT SYMBOLS: WL: Water Level WS: While Sampling WCI: Wet Cave in WD: While Drilling DCI: Dry Cave in BCR: Before Casing Removal AB: After Boring ACR: After Casing Removal Water levels indicated on the boring logs are the levels measured in the borings at the times indicated. Groundwater levels at other times and other locations across the site could vary. In pervious soils, 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 descriptors 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-plastic. 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 soils on the basis of their consistency.

The sediments may be composed of particles or pre-existing rocks derived by mechanical weathering, evaporation or by chemical or organic origin. The sediments are usually indurated by cementation or compaction. Chert Very fine-grained siliceous rock composed of micro-crystalline or cyrptocrystalline quartz, chalcedony or opal. Chert is various colored , porous to dense, hard and has a conchoidat to splintery fracture. Claystone Fine-grained rock composed of or derived by erosion of silts and clays or any rock containing clay. Soft massive and may contain carbonate minerals. Conglomerate Rock consisting of a considerable amount of rounded gravel , sand and cobbles with or without interstitial or cementing material. The cementing or interstitial material may be quartz, opal , calcite, dolomite, clay, iron oxides or other materials. Dolomite A fine-grained carbonate rock consisting of the mineral dolomite [CaMg(CO3)2]. May contain noncarbonate impurities such as quartz, chert, clay minerals, organic matter, gypsum and sulfides. Reacts with hydrochloric acid (HCL) . Limestone A fine-grained carbonate rock consisting of the mineral calcite (CaCO3) . May contain noncarbonate impurities such as quartz, chert, clay minerals, organic matter, gypsum and sulfides. Reacts with hydrochloric acid (HCL) . Sandstone Rock consisting of particles of sand with or without interstitial and cementing materials. The cementing or interstitial material may be quartz, opal, calcite, dolomite, clay, iron oxides or other material . Shale Fine-grained rock composed of or derived by erosion of silts and clays or any rock containing clay. Shale is hard , platy, of fissile may be gray, black, reddish or green and may contain some carbonate minerals (calcareous shale) . Siltstone Fine grained rock composed of or derived by erosion of silts or rock containing silt. Siltstones consist predominantly of silt sized particles (0. 0625 to 0. 002 mm in diameter) and are intermediate rocks between claystones and sandstones and may contain carbonate minerals. lierracon LABORATORY TEST SIGNIFICANCE AND PURPOSE TEST SIGNIFICANCE PURPOSE California Bearing Used to evaluate the potential strength of subgrade soil, Pavement Thickness Ratio subbase, and base course material , including recycled Design materials for use in road and airfield pavements.

ESAL Equivalent Single Axle Load, a criteria used to convert traffic to a uniform standard, (18,000 pound axle loads). Engineered Fill Specified material placed and compacted to specified density and/or moisture conditions under observations of a representative of a geotechnical engineer. Equivalent Fluid A hypothetical fluid having a unit weight such that it will produce a pressure against a lateral support presumed to be equivalent to that produced by the actual soil. This simplified approach is valid only when deformation conditions are such that the pressure increases linearly with depth and the wall friction is neglected. Existing Fill (or Materials deposited throughout the action of man prior to exploration of the site. Man-Made Fill) Existing Grade The ground surface at the time of field exploration. lierracon REPORT TERMINOLOGY (Based on ASTM D653) Expansive The potential of a soil to expand (increase in volume) due to absorption of moisture. Potential Finished Grade The final grade created as a part of the project. Footing A portion of the foundation of a structure that transmits loads directly to the soil. Foundation The lower part of a structure that transmits the loads to the soil or bedrock. Frost Depth The depth at which the ground becomes frozen during the winter season. Grade Beam A foundation element or wall, typically constructed of reinforced concrete, used to span between other foundation elements such as drilled piers. Groundwater Subsurface water found in the zone of saturation of soils or within fractures in bedrock. Heave Upward movement. Lithologic The characteristics which describe the composition and texture of soil and rock by observation. Native Grade The naturally occurring ground surface. Native Soil Naturally occurring on-site soil, sometimes referred to as natural soil . Optimum Moisture The water content at which a soil can be compacted to a maximum dry unit weight by a Content given compactive effort.
