At any given time, mining and reclamation may be occurring in one or more phases to accommodate the blending of materials, the natural progression of mining from one Phase to the next, and the relocation of the processing plant and settling ponds This "concurrent reclamation" allows for reclamation work being completed in one phase while mining begins in another phase The "direction of mining" arrows on MAP EXHIBIT C-1 - MINING PLAN MAP show the applicant's best guess on how mining will progress through the mine areas at this time Natural ground conditions and unforeseen circumstances may necessitate changes to the mining direction throughout the life of the mine The RECLAMATION COST ESTIMATE- EXHIBIT L is based on an estimated disturbance area when the mine has been open for a few years The acreage disturbed may increase or decrease as mining progresses As mining moves from one Phase to another a bond review will be completed prior to moving into the new area In this review the current bond would be compared with a cost to reclaim the next phase, plus any reclamation left in the current disturbed area The in -progress items like, working face grading, reclaiming stripped areas and armoring placement costs will be updated and transfer to the new area Reclamation activities in the existing area will be reduced as appropriate if they are complete and the Surety will be adjusted as needed Initial mine development will begin on the south end of Phase 3 and in Phase 1A where the topsoil and overburden will be stripped and stockpiled around the disturbed area Some of this material will be used to construct a sight berm along the east sides of Phases 1A and 3 to limit visibility from Highway 85 into the active mining and processing areas Any material not used for the sight berm construction will be stockpiled on the north end of Phase 3 for placement in Phase lA once all sand and gravel have been mined The berms will vary in height depending on the area to be screened, with 3.1 slopes on each side During the stripping process, any structures owned by the Cannon Land Company that will not remain after reclamation is complete will be removed and disposed of properly, this applies to all Phases. Mining will start on the south end of Phase 1A and progress to the north The setbacks to be used are shown in the table on the MAP EXHIBIT C-1 - MINING PLAN MAP The aggregates will be removed and stored on the Plant Site area in Phase 3 for processing This stage will then become a settling pond and excess overburden backfill area, from the development of the reservoirs in Phase 1, Phase 2 and Phase 3 As mentioned due to unforeseen variations in the structure owners, sequentially from above, the proposed mining sequence may change circumstances such as market conditions, natural deposit, agreement restrictions with etc At this time, the plan is to mine them 1 thru 6 as shown on the maps.

Phases 2A, 4A, 4B, and 5A will be mined as described for Phase lA and prior to, or in conjunction with, mining beginning in the corresponding reservoir phase in order to provide areas for disposal of excess overburden and processing fines for those areas. Sight berms will be constructed along the Railroad ROW on the west sides of Phase 4, 4B, 5 and 6 as noted for Phase 3 above The following mining methods will apply to all of the reservoir Phases Operations will begin in each Phase of reservoir construction by stripping the area where mining will start Initially a 30 acre area will be stripped and periodically as mining progresses it will be extended so there is approximately 30 acres ready for mining at any -one-time as each Phase is mined. The topsoil needed for resoiling the above -water areas will be separated from the overburden and stored around the mining area for use in reclamation Once enough topsoil is salvaged to resoil the above -water disturbed areas with an average of 6-12 inches, the rest may be sold These stockpiles will be placed strategically in progression with mining, and in some cases the stripped topsoil will be placed on areas where grading and shaping are complete so it only has to be handled once In Phases 1 and 2, all topsoil storage piles will be located as far from the river as practical, and will run parallel to the river's flow if located in the floodplain During the stripping, a slurry wall pad will be built around the reservoir Phase mining area using the excess topsoil and overburden When the slurry wall pad has been completed, the bentonite slurry wall construction will begin This is done by excavating a trench in the pad that is keyed into the underlying bedrock and filled with a mix of overburden, bentonite and water to create the slurry that becomes the liner. The overburden not used in slurry wall construction will be placed in the disposal areas or sold After the slurry wall liner is place within a phase, a dewatering trench will be excavated. Then a pump will be installed and dewatering will begin This will allow the area within the slurry wall to be dry mined The trench will be extended around the area as mining progresses The active mining area in the reservoir phase will remain dry After mining is completed, final reclamation of the phase can be completed, including liner certification, final grading of slopes and initial seeding for revegetation At this time, the reservoir will be turned over to the owners They will be overseeing construction to complete the reservoir operations facilities and filling As mentioned previously, any developed water storage facility construction that the landowners complete falls under Reclamation Option B and L G Everist will file a Technical Revision to incorporate the changes Dewatering as mining progresses facilitates early testing of the slurry wall liner, which is required to receive liner approval certification from the State Engineer's office In general, mining will commence in the south end of each L G Evenst, Inc- Ragsdale Reservoirs June 11, 2020 D-7 EXHIBIT D MINING PLAN (cow) Phase and work north (except for Phase 1, where mining will start in the north and progress south) As noted above, the Alpha suffix stages will be mined first in each general area to provide areas for disposal of excess overburden and processing fines generated from the mine The working face will be mined near vertical to maximize removal of material from the mine At its widest point, the working face will be approximately 2600 feet long If mining ends prematurely, this working face slope will be reclaimed using a cut/fill sloping method instead of backfilling As mining reaches the vertical face setbacks limits around each reservoir, mining in this band from the top of the slope to the vertical face limit will change to a slope mining method to leave the 3 1 final slope We expect to have no more than 2600 linear feet of area needing final exterior sloping at any -one-time. The mining setbacks will vary from the permit boundary and structures as allowed by each agreement for said structures and/or the Geotechnical Stability Analysis The proposed setbacks are shown in the Setback Table on MAP EXHIBIT C-1 - MINING PLAN MAP For example, on oil/gas wells, we will maintain a 150 foot radius around each well -head since we plan to leave the natural gravel slope in the reservoirs The MAP EXHIBIT C-1 -MINING PLAN MAP shows how this will look The setbacks will be used as a place for access roads to the mine exterior, ditches and oil and gas facilities. The setback areas will be reclaimed if disturbed, but most roads will remain for reservoir access as part of the reclamation plan. The material will be mined using loaders and track hoes (excavators) to remove material from the face The material will then be delivered to the Plant for processing using haul trucks or a conveyor system No blasting will take place at this mine The arrows on MAP EXHIBIT C-1 - MINING PLAN MAP show how we will progress thru the mine area. Reclamation will run concurrent with mining to control the amount of disturbed area in the mine at any- one -time A reclamation cost estimate is presented in Exhibit L for start of mining proposed in the following text This pit will be operated year -around by L G Everist, Inc., weather permitting There may be periods when the demands for material are slow and no mining will take place, creating an intermittent operations situation The amount of disturbance to be bonded will allow 180 acres or less at any -one-time Of this 180 acres, the Plant Site will cover 65 acres, containing processing plant/stockpile area, equipment storage area, temporary overburden and topsoil piles, drying pads and other axillary uses needed at the mine.

Cannon Land Company, the landowner, will be responsible for the construction of any additional reservoir operations facilities (pump houses, inlet/outlet structures, etc ) on each reservoir once L G Everist, Inc has resoiled and seeded the perimeters and released a Phase from the DRMS permit The reclamation methods and plans described below will apply to all Phases but may require minor variation depending on the conditions found in each Phase Reclamation will run concurrent with mining so it will commence as soon as enough area is available to reclaim and not be redisturbed The setbacks and side slopes from the water's edge to the slurry wall or setback limit will be resoiled and revegetated using the methods described in the following plan On -site generated inert material will be placed in backfill areas or will be recycled/sold The applicant proposes bonding to cover the amount of disturbance throughout the mine (180 acres), including a sufficient length of liner and sloping, acres of seeding, backfilling, armoring etc If the applicant determines that the amount of disturbance at the mine may soon exceed the bonded amount, the applicant shall submit a bond revision to the Division As noted in the MINING PLAN, we are proposing two options for reclaiming the site The methods used to develop the reservoirs in each option have minor differences The differences being in how Phases 2, 4, 5 and 6 are developed around existing oil/gas facilities that may be relocated or removed in the near future. Please refer to TABLEE-1 RECLAMATION TIMETABLE -OPTION A or TABLE E-2 RECLAMATION TIMETABLE -OPTION B for information on each Option and Phase changes for the Reclamation Currently, the proposed mine site is primarily irrigated agricultural land, but is broken into 5 different use areas The current uses are, irrigated crop areas, non -irrigated pasture, ditch and return flow corridors, and also oil/gas operations areas with some high capacity gas pipeline ROW's. The agricultural uses will continue in areas where mining operations have not yet begun There is very little native vegetation present on the agricultural areas because of the intensive agricultural practices that have taken place on the land In most cases, the oil/gas operations areas have little vegetation and the high pressure gasline ROW's L G Evenst, Inc- Ragsdale Reservoirs June 11, 2020 E-1 EXHIBIT E RECLAMATION PLAN (coNr) have been farmed for many years and the vegetation cover on those areas is consistent with farmed areas The narrow bands along the Cannon return flow ditch, the Platte Valley Canal and Platteville Ditch have been consistently disturbed by ditch maintenance This leaves only isolated areas around the permit area with vegetation that may be considered native. The typical vegetation descriptions in EXHIBITSI&Jwill will not match the actual current vegetation since the practice for the agricultural activities are that crops are rotated from year to year RECLAMATION PLAN FOR RESERVOIR AREAS This section covers reclamation on the developed water storage reservoirs in Phases 1 thru 6 As discussed in the Mining Plan text, reclamation will run concurrent with mining Initially this will happen when the reservoir slopes area is being mined and graded The plan is to leave undisturbed natural sand and gravel at 3v lh slopes in each reservoir phase The 3h to lv slope of natural, undisturbed materials will need no other reclamation except minor grading to dress the slope. This section covers reclamation on the developed water storage reservoirs in Phases 1 thru 6 As discussed in the Mining Plan text, reclamation will run concurrent with mining Initially this will happen when the reservoir slopes area is being mined and graded The plan is to leave undisturbed natural sand and gravel at 3v lh slopes in each reservoir phase. The 3h to lv slope of natural, undisturbed materials will need no other reclamation except minor grading to dress the slope Since the perimeter of the reservoirs will be mined to their final slopes, only minor amounts of slope work will be necessary as mining ends. This will also insure, that if mining ceases before the resource is exhausted, only a minor amount of work would have to be done to finish reclamation on the disturbed area At this time, the final reservoir levels are estimated to be at the lowest crest elevation around any given reservoir The temporary topsoil stockpiles in the various mining phases will be available for reclamation needs When grading and shaping is completed on a large section of reservoir banks, they will be resoiled and then seeded during the next seasonal planting window The MAP EXHIBIT F - RECLAMATION PLAN MAP - OPTION A and OPTION B show the sloping plans and areas that will be reservoir areas in this plan All reservoir bank sloping will be completed to the stated 3 1 slopes or flatter All areas that are above the high water line, and are not being reclaimed as graveled access roadways, will have an average of 6-12 inches of soil fully replaced and prepped for L G Evenst, Inc- Ragsdale Reservoirs June 11, 2020 E-2 EXHIBIT E RECLAMATION PLAN (corer) seeding All top soiled areas will be seeded with the seed mix described in this plan, and effective weed control measures will be implemented until the Phase is released from the permit area As mentioned in the Mining Plan, if the reservoir phase acreage is not released from the DRMS permit, and the landowner constructs developed water storage facilities that are not in this reclamation plan, then L G Everist will file a Technical Revision to incorporate the changes RECLAMATION PLAN FOR BACKFILL AREAS This section covers reclamation on the developed water storage reservoirs in Phase 1A, 2A, 4A, 4B, AND 5A The 5 areas have commercial deposits of gravel but are too small or too shallow to develop as water storage reservoirs It was also determined that with the amount of overburden on the reservoir areas, there is not a large enough demand to sell all the overburden that will be stripped The mining plan calls for leaving the side slopes of these areas graded 3h to lv when mining ends to leave a stable slope during backfilling and so they would not have to be graded if backfilling does not fill them completely They will then be backfilled using the excess overburden from the initial stripping of a phase and the fines generated during processing of the raw sand and gravel At any given time, backfilling may be taking place on 2 or more Phases as shown on the MAP EXHIBIT C-1 -MINING PLAN MAP The intent is to fill Phase 1A, 2A and 4B to their existing elevations Phases 4A and 5A may be filled above the original grade in some areas to dispose of excess overburden Estimates show that it is possible to complete the backfilling in these Phases as shown on MAP EXHIBIT F - RECLAMATION PLAN MAP - OPTION A and OPTIONBif if the amount of overburden is present. At a minimum, each backfilled Phase will be backfilled to a level at least 2 feet above the highest ground water elevations if there is not sufficient material to bring them back to their original elevation Once backfilling is complete in a Phase, an average of 6-12 inches of topsoil will be spread over the disturbed area and it will be seeded as cropland during the next planting season Optional Reclamation Plans Note that all changes connected with the following optional plans will take place within the permitted boundaries, therefore not affecting (increasing) the overall acreage of the permitted area and guaranteeing the allowed use of the Technical Revision process for these changes RESERVOIR AREAS L G Evenst, Inc - Ragsdale Reservoirs June 11, 2020 E-3 EXHIBIT E RECLAMATION PLAN (corn) We are submitting two options for a final configuration of the reservoir areas These are based on the current and future status of various oil/gas facilities located in the permit area Option A - The reservoir configurations for Option A are show on the large map on MAP EXHIBIT F - RECLAMATION PLAN MAP - OPTION A and the areas are shown on the Reclamation timetable for Option A. Option B - The reservoir configurations under Option B are shown on MAP EXHIBIT F - RECLAMATION PLAN MAP - OPTION B and the areas are shown on the Reclamation timetable for Option B In general, the optional changes in Option B could be caused by oil and gas facility changes, other utility and ROW changes, and changes by the landowner Changes by the landowners could include their construction of developed water storage facilities prior to acreage release in a reservoir phase, or transforming a backfill phase into a wetland area, for wetland banking by the landowner If any options of Option B are chosen, L G Everist will submit a Technical Revision to incorporate the changes The methods used to reclaim the reservoirs will be the same for both options as previously discussed The difference may be an increase/decrease in the volume of developed water storage and an increase/decrease in the amount of revegetation necessary We do not know when Mining Option B or Reclamation Option B or some part(s) of either or both will be implemented, but we are including these optional plans to increase the flexibility of this permit and account for inevitable changes when mining the site As mentioned previously, whenever any part(s) of the Option B plans become feasible, we will file a Technical Revision(s) to the Division to provide revised Mining and/or Reclamation Map(s) that will show the changes The Technical Revision(s) will discuss any changes needed to implement the optional changes, including a discussion on changes in disturbed areas, slurry wall lengths and revegetated areas. GENERAL DISCUSSION There are sufficient amounts of topsoil on the site so the mined areas can be resoiled to an average depth of 6-12 inches Sufficient topsoil will be saved for use in reclamation. The available topsoil to be salvaged from the stripping process will preclude having to haul additional soils onto the site for revegetation The existing soils on the property have been capable of producing healthy crops and grasses and are expected to work for use on mined areas that will be revegetated The vegetation information was obtained from site visits and data provided in the vegetation information obtained from the NRCS soil survey web page A copy if that report is in EXHIBITIANDJ and describes the current soils and vegetation on the properties As outlined in the ExHisITD-MININGPLAN, approximately 508 acres ± of the permitted area will be disturbed as a result of mining activities The plan calls for initially bonding to have 180 00 acres ± disturbed at any -one-time and the disturbed area may be divided between as many as two (2) Reservoir Phases and 2-3 Backfill l l Phases as shown on the MAP EXHIBIT C-1 -MINING PLAN MAP As mining progresses across the property some parts of the property L G Evenst, Inc - Ragsdale Reservoirs June 11, 2020 E-4 EXHIBIT E RECLAMATION PLAN (carer) will remain undisturbed while other areas will be either, stripped, mined, partially reclaimed or totally reclaimed. The MAP EXHIBIT C-1- MININGPLAN MAP shows how the pit will look if it were totally mined The MAP EXHIBIT F - RECLAMATION PLAN MAP - OPTION A and OPTION B show how the area will look when reclamation is complete The area will be returned to at least its present vegetative condition when reclamation is complete Careful analysis of the growth medium and salvageable soil will permit the operator to carry out a soil additive program and to monitor the prescribed seeding plan to determine if the plan requires revision Under normal weather conditions, an adequate moisture reserve will be present for establishment of the proposed seed mixture Irrigation is planned for the crop areas on the backfilled Phases, but will not be used for the reservoir perimeters. No revegetation will take place on undisturbed areas, roads or oil/gas operations access roads or facilities The reclamation timetables show the types and amount of land use in each Phase when reclamation is complete Approximately 14% of the area in the permit will not be disturbed by mining, either because it is setbacks around well facilities, gaslines ROW's, along the ditches and areas too small to mine that will be kept in their natural state REVEGETATION PROGRAM The revegetation program to be implemented on the areas to be seeded with grass by L G Everist is detailed below The topsoiling plan presented above and this revegetation program are devised after careful review of the existing soil conditions and present vegetation, both on the site and in the NRCS report "Revegetation will be carried out in such a way so as to establish a diverse, effective and long-lasting vegetative cover that is capable of self -regeneration without continued dependence on irrigation, soil amendments or fertilizers " The plan is designed to create a vegetative cover around the reservoirs that is at least equal in extent to the cover of natural vegetation before mining. The use of species native to the area are included Since the intended use of the reclaimed land along the reservoirs is rangeland, any slopes created will be commensurate with this final land use Seed will be drilled wherever possible, when drilling is not possible, the seed will be broadcast The revegetation plan provides for the greatest probability of success in plant establishment and vegetative development by considering environmental factors such as seasonal patterns of precipitation, temperatures and wind Other considerations, such as soil texture, fertility, slope stability and the direction in which slopes face, have been considered A weed control plan is included in this plan Graveled maintenance roads will be built around each reservoir and around each gas/oil well where no seeding or resoiling will take place This will provide room around each well or reservoir to service it as needed by the well or reservoir owners The access roads are shown on the MAP EXHIBIT F - RECLAMATION PLAN MAP - OPTION A and OPTION B L G Evenst, Inc - Ragsdale Reservoirs June 11, 2020 E-5 EXHIBIT E RECLAMATION PLAN (coNT) SEEDBED PREPARATION When mining on an area is complete or there is room to begin reclamation, any compacted areas will be ripped and scarified to created a deeper root zone under the resoiled areas Once this is complete, the stockpiled soils will be spread If tests show a fertilizer is needed, it will be broadcast spread on the seedbed at an adequate rate suggested by NRCS or a seeding/revegetation contractor On the areas where seed is broadcast, the surface will be left fairly rough to trap the seed and keep it from being affected by wind SEEDING TIME The grass seed mixture will be planted from early fall through spring (November through May) The time of planting will be controlled by when the resoiled areas are ready for planting If fall planting is convenient, the seeding will be done before the first freeze (about the time Winterwheat is planted) If spring planting is called for, it will be done in March or April, weather permitting, after the last frost Both periods assure there will be adequate residual ground moisture available for the newly planted seeds For areas that will be planted with crops, the crops planted will be determined by the Landowners or farmers who handle crop planting now GRASSES The following seed mix was developed by the NRCS office in Brighton many years ago and is used on all L G Everist mining operations in Weld County It has proven to be very reliable This mix will place approximately 41 2 seeds per pound per sq-ft as prescribed by the NRCS planting guidelines If the seed is broadcast, the amount will be doubled and spread on a rough surface The seeded areas will then be dragged or raked thoroughly to set the seed Under normal conditions, the operator will strive for a 30 to 40 percent cover rate on the grass revegetated areas when reclamation is complete No trees will be planted, because they are not compatible with reservoir development as their root systems affect the liners It is expected some natural invasion from adjoining areas will occur PROPOSED SEED MIX Species Lbs PLS/Acre Western Wheatgrass (Aribba) 5 0 Big Bluestem (Champ) 2 5 Blue Grama (Hachita) 0 6 Switchgrass (Blackwell) 1 75 Total 9 85 It has been our experience on other operations, that the seeded area will have a heavy cover of weeds after the first year The second year, there are fewer weeds as the grasses start to take hold By the third year the weeds are mostly gone and the grass L G Evenst, Inc- Ragsdale Reservoirs June 11, 2020 E-6 EXHIBIT E RECLAMATION PLAN (coNT) has established itself so it will grow in future years These weeds also tend to shade the seedbed, retain snow in the winter and act as a wind break for the newly emerging grasses The area will then be monitored for success of revegetation until it is released from the permit area by the Mined Land Reclamation Board WEED CONTROL The revegetated areas will be monitored closely each spring for the first two years to determine if noxious weeds are invading the area L G Everist, Inc will implement a weed monitoring and control plan that covers the areas actively used by their operations Weed control on the agricultural use areas will be the responsibility of the landowner or farmer using the land Weed control in the mining and reclamation areas will be initiated if the problem becomes serious or if an excessive weed cover is still present at the end of the second year In no way should this be taken to mean that L G. Everist will try to eradicate all the weeds from the site Some weeds are beneficial to the upland game species in the area, they provide important protection from the elements during winter, and nesting sites during the spring Total eradication of weeds from the site is not necessarily desirable or possible, so we will be using stronger controls on the noxious weeds and controlling the rest as needed Weed control may be done through mowing or chemical means. Control of noxious weeds is important to the state, so we will follow USDA Extension Service recommendations to control them Our Weed Control Plan is included in the APPENDIX. IRRIGATION No irrigation is planned for the revegetated area around the reservoirs It makes the vegetation dependent on water and does not promote a vegetation cover that is diverse and capable of self regeneration On cropland area irrigation may be used by the landowners RECLAMATION PERFORMANCE STANDARDS (The following information is presented to address specific parts or Rule 3 as required by the MLRB Rules and Regulations ) The operator intends to mine the property in compliance with the Reclamation Performance Standards of Rule 3 Grading will be done to create a final topography that is compatible with the intended final land use The slope in the developed water storage reservoirs will be mined to their final slopes These slopes will be 3 1 and on the backfilled areas we will attempt to retain the present drainage pattern across the property A mine entrance sign that conforms to the requirements in Rule 3 1 12 (1996) will be installed at the entrance to this facility prior to commencement of mining. The material used to create the slopes will be native material found on the site It will consist of sand, gravel, overburden and topsoil The Phases will be reclaimed so that a suitable grade for L G Evenst, Inc- Ragsdale Reservoirs June 11, 2020 E-7 EXHIBIT E RECLAMATION PLAN (cow) drainage exists All surface runoff will be directed into the excavated area or natural existing drainages around the site All grading will be done in a manner to control erosion and to protect areas outside the affected lands All backfilling and grading will be completed as soon as feasible after mining is completed All refuse will be hauled away or disposed of in a manner that will control unsightliness and protect drainage systems from pollution. There are no acid-forming or toxic materials inherent in the sand and gravel deposit If petroleum products are stored at the site for mining equipment and operations, they will be stored as prescribed by applicable laws Any storage tanks will be surrounded by a berm or be of the latest construction, adequate to contain any fluid spilled, should a tank rupture. In addition, there is adequate absorbent materials on site to contain any spills that would occur There are no drill or auger holes on the land Maximum slopes will be within the limits set forth in the Rules and Regulations of the Board and will be capable of being traversed by machinery The operator does not expect prevailing hydrologic conditions to be disturbed L G Everist will comply with applicable Colorado water laws and regulations (as the operator understands them) which govern existing water rights The operator does not expect to adversely affect the prevailing hydrologic balance of the affected land and surrounding areas Nor does the operator expect to affect the quality of water in surface and ground -water systems both during and after the mining operation and during reclamation In addition, the operator shall comply with applicable Federal and Colorado water quality laws and regulations Any water used in the mining operation and the processing plants will come from water owned or leased by L.G Everist and legally suitable for use in mining operations EXHIBITG-WATER INFORMATION contains specific information concerning impacts and uses of water at this mining operation No dredging takes place at this facility, there are no temporary siltation structures involved in this operation and no mining will be done in a river or waters of the United States A U.S Army Corps of Engineers Permit is not required for this operation because no jurisdictional wetlands will be disturbed by mining or other activities on the site Settling ponds will be constructed on the site to collect water from the material washing at the processing plant(s) The fines in the wash -water settle out in the ponds and the water is then recirculated to be used again in the processing plant Groundwater collected from dewatering trenches may be discharged from the site, after any natural fines have settled out . The discharged groundwater quantities shall be measured and sampled as per the requirements under a CDPS - Sand and Gravel Mining Process Water and Stormwater Combined Permit There will be no earthen dams on the mined area The mining and reclamation plans have taken existing wildlife conditions into consideration The final reclamation will enhance the area for wildlife use The mining and reclamation plans allow for the safety and protection of wildlife remaining on the mine site, at the processing site and along all access roads to the site In practice this is done by limiting the amount of L G Everist, Inc- Ragsdale Reservoirs June 11, 2020 E-8 EXHIBIT E RECLAMATION PLAN (corer) disturbance, restricting truck and equipment speeds to 15 mph or less and doing concurrent reclamation Mine employees are trained to deal with wildlife found on the mine during operating hours to avoiding harming them See EXHIBITH-WILDLIFE for more information As mentioned previously, topsoil in the property is of good quality, so it should be a decent growth medium for reclamation When topsoil is removed, to reach the sand and gravel deposit, it will be segregated and stored in graded stockpiles, generally located in areas where disturbances by ongoing mining operations will be at a minimum, i e , along setbacks on the pit perimeter. If the topsoil (and overburden) stockpiles remain undisturbed for more than a year, the approved seed mix will be applied to prevent erosion, to control weeds, and to keep them viable for reclamation Fertilizer and other soil amendments may be used as discussed in this plan RECLAMATION TIMETABLE Reclamation will begin once enough area has been opened so that any reclamation completed will not be disturbed as mining progresses This may take 5 or more years depending on the economic conditions in the area and the amount of material mined The operator anticipates approximately 80% of the total mined land will be reclaimed by the time mining is completed If revegetation problems occur before release, an analysis of the problem area will be done and the area will be revegetated again as necessary The seed mixture and rates may be revised as needed to complete reclamation, if a substantial modification is required, the Division will be notified prior to making the change This gives us the most flexibility to complete reclamation successfully Table E-1: Reclamation Phases -Option A Area Years ACRES ± .

None of these ditches will be disturbed by mining In addition, the western and eastern areas of the mine are divided by a Transportation Corridor which contains U S. Highway 85 and the Union Pacific Rail Road tracks This transportation corridor will not be mined.Based on regional groundwater studies and the experience gained by L.G. Everist, Inc. during numerous previous permit applications they have found that slurry wall liners mitigate any impacts to groundwater on nearby areas surrounding a lined reservoir Additionally, the ditches, river and streams lying across or around the site will limit groundwater mounding or shadowing If any significant groundwater changes do occur, they can be mitigated as discussed below. Mitigation Trigger Starting in October 2019, L G. Everist, Inc. began to collect groundwater elevations from newly installed monitoring wells on and around the mine area to establish historic ground water elevations around and on the site. A 2 -year period from October 2019 to September 2021 will be used as the baseline for triggering mitigation actions. Mining will start in Phase 1-A, which is the first unlined area. The depth to ground water in this Phase - according to the data collected - is an average of 17.5 feet below the surface, so shallow mining work can be done without exposing groundwater. This will give time to collect the 5 quarters of data before any potential impacts could occur to adjoining wells The baseline data needed for the areas will be in place before installation of the slurry walls begins. There are outside influences not caused by any mining operations of L.G Everist, Inc. These outside influences that have been acting on the groundwater levels will continue to L G Evenst, Inc Ragsdale Reservoirs May 5, 2020 27 Exhibit G Water Information (cont) influence the groundwater levels and impact the baseline range and trigger point. The natural groundwater depths vary from 3.5 to 8.8 feet below the surface in Phases 1 and 2 when they were measured in March -2019. The seasonal operation of the unlined irrigation return flow ditch that crosses the permit area on the west will affect groundwater levels and could help with any mitigation needs in the Phases west of the highway. Between the Platteville Ditch and the Railroad in Phases 4, 5, & 6, the groundwater depth varies from 3 to 24 feet below the surface, when measured in March -2019 Groundwater depths can vary significantly through seasons and years, depending on many influences, including, climate, precipitation, irrigation, other pumping rights, and much more. L G. Everist, Inc's experience on other mines in the South Platte River valley indicates that groundwater levels can fluctuate as much as 7+ feet depending on the season In a normal mitigation trigger plan, the trigger limits would be set at 3 foot change plus or minus change over a 3 -month average. Realistically, in this case the trigger number should be based on a 3 -foot change determined by a line that approximates a up or downward trend of the water table and considers outside impacts such as, drought, adjoining mining activities, storm events or decreased irrigation activities. At the current time, there is no mounding mitigation plan for when the water table increases We do not expect this to be a problem where the slurry walls are in close proximity to a flowing water body like the ditches, return flow ditch and the South Platte River Mounding would be controlled by those water surfaces and it would only affect Cannon Land Company areas around the reservoirs On the east side of the Platte Valley Canal, the ground -water table averages 11 feet deep and there are enough unlined areas crossing thru the lined reservoirs to allow for some increase without impacting surface features. In the eastern area groundwater averages 12 feet below the surface, there are numerous, gaslines and road corridors that would allow ground water to bypass the lined areas The mining operation will have minimal effect on the South Platte River in the form of minor groundwater depletions due to evaporation and water uses associated with mining The depletions to the South Platte will be mitigated thru a temporary Substitute Water Supply Plan (as required and approved by the Division of Water Resources) to prevent injury to the vested senior water rights. The reclamation plan proposes the creation of 8 (or fewer) slurry wall lined reservoirs that will not be hydraulically L G Evenst, Inc Ragsdale Reservoirs May 5, 2020 28 Exhibit G Water Information (cont) connected to the South Platte River or any alluvial aquifer The Mining Plan includes four (4) unlined pits that will be backfilled with excess overburden and wash fines from the sand and gravel processing plant. The reservoir phases will be sealed prior to mining, thereby eliminating the groundwater drawdown which is typically associated with mine site dewatering This will also eliminate or minimize the possibility of any adverse impacts to nearby alluvial wells If during the course of mining or reclamation complaints from a well owner are received by the permittee, the permittee will commence an evaluation and investigation, including providing replacement water to the well owner if necessary, within 48 hours. DRMS shall be notified within two business days of the complaint and the proposed initial steps for the evaluation of the complaint. A written report will be submitted to DRMS within 30 days detailing the information collected during the investigation of the complaint, and proposed mitigation activity, if required. Potential Water Resource Impacts Ground Water Wells We expect this mining operation will have no or minimal impacts on the prevailing hydrologic balance Sand and gravel mining related impacts to groundwater wells near the pit will be mitigated through the installation of slurry walls around the perimeter of new reservoir mining phases prior to the start of dewatering in each reservoir phase (see EXHIBIT D - MINING PLAN) TABLE G-1 is a list of 16 wells from the Office of the State Engineer's files, and whose permit locations are within 200 feet of the permit area (Note Well permit locations are not always accurate, especially for older wells ) The wells highlighted in blue are outside the permit area (which is owned by Cannon Land Company) Cannon owns 12 wells Of the 4 highlighted wells not owned by Cannon, one (1) well is a deep well (highlighted dark blue) and three (3) wells are shallow wells drawing water from the surface aquifer (highlighted light blue or green) The green highlighted well is the only surface residential and the light blue are irrigation wells. Prior to exposing groundwater or installing a slurry wall liner in any Phase, a well survey will be performed on any wells within 200 feet of that Phase not owned by Cannon Land Company. The only well that will not be tested will be the Pacheco well, because it is in excess of 600 feet deep and will not be affected by potential surface impacts due to mining L G Everist will attempt to obtain for each well to be tested the following data, L G Evenst, Inc Ragsdale Reservoirs May 5, 2020 29 Exhibit G Water Information (cont) in addition to whatever basic well construction data is currently available • Total well depth • Depth to static water level, • Depth of pump intake • Conduct pump test to determine well yield (subject to SEO Regulations) • Conduct analytical sampling of parameters for any residential all Domestic Drinking Water wells. All data collection will be completed at L.G Everist's expense. Data will be provided to DRMS and the well owner upon their request. If a well owner chooses not to allow the permittee access to collect the above data, they will be provided with a form that they can sign and date to document that they have been provided with an opportunity to have their well characterized at the permittee's expense, but have chosen to decline to participate L G. Everist, Inc has installed 14 piezometers (a.k.a Monitoring Wells) around the mine Their locations are shown on the maps and on MAP Emu'. G-1 WELLMAP. L G. Everist started data collection in October 2019 and will do monthly readings throughout the life of the mine. We will provide a summary of the data yearly with the Annual Report Post Reclamation Any slight groundwater mounding and shadowing associated with the slurry wall sealed portions of the pit are not anticipated to produce any adverse impacts to adjacent properties Potential groundwater mounding in the western parcel will be mitigated by the South Platte River, the Platte Valley Canal, and the irrigation return flow ditch, and on the eastern areas by the Platteville Ditch. These existing water features will serve to regulate and balance groundwater elevations in the alluvium adjacent to the sealed pits. The backfilling in Phases 4A, 4B and 5A is not anticipated to produce any adverse impacts to adjacent properties, since the phases are surrounded by unlined areas that will carry ground water around the backfill The operator does not anticipate any long-term post - reclamation ground water depletions, but if there are any, they would be replaced through a Colorado Water Court approved Plan of Augmentation. L G Everist, Inc has entered into a contract to mine the gravel and construct the developed water storage reservoirs with L G Evenst, Inc Ragsdale Reservoirs May 5, 2020 30 Exhibit G Water Information (cont) Cannon Land Company. As water storage reservoirs are completed, they will be turned over to Cannon for further development into developed water storage reservoirs. L.G Everist will submit Technical Revisions to the DRMS if Cannon makes changes prior to L G Everist receiving final reclamation approval and acreage releases from the Division. Discharge Permits Surface Water Management When necessary, ground water will be pumped and discharged from the Ragsdale Reservoirs mine under a CDPS Permit which the operator will obtain from the Colorado Department of Public Health and Environment, Water Quality Control Division (CDPHE- WQCD). This permit will remain active during the life of the mine The discharge points may change as mining progresses and all necessary changes will be submitted to the WQCD for modifications to the discharge points Runoff from disturbed areas will be managed and controlled to protect against pollution, of either surface or groundwater through the implementation best management practices which include sloping disturbed areas inward toward the site, vegetating berms and other disturbed areas, and other site - specific controls as needed.

and this area is not being mined Bald Eagles have been removed from the Threatened and Endangered list however they still fall under the Migratory Bird act As noted above, there is an old nest on an adjoining property and a roost area mapped along the river northwest of the permit area Mining will not take place close to this area prior to mining in Phase 2A During the time prior to mining in Phase 2A and the other mining phases, additional observations will be made to determine what actions are needed, if any, to prevent any conflicts with the mine's operation and any eagle activity If any eagles are observed, the Denver Office of the Colorado Parks and Wildlife (CPW) will be contacted to confirm the observations and advise L G Everist on what actions should be taken to avoid disrupting the sites during nesting times L G Everist will then take the appropriate actions to minimize distur- bance to the nest or roost area Project Effects to Wildlife Existing wildlife in the area is not expected to be signifi- cantly impacted by mining at this site Temporary and permanent losses of food and habitat are not expected to be significant as the area of disturbance will be limited to less than 30% of the permit area at any given time Haul road speed limits will be limited to 15 MPH or less There may be some displacement of smaller birds and mammals during active mining operations in a phase, but once a reser- voir is developed it will increase the habitat for shorebirds and water fowl The revegetated areas may become habitat for small mam- mals There will be no mining within the river corridor area, there- fore leaving a transit area for larger wildlife and scavengers along the river to bypass the mining area The ditch ROW's and irrigation return flow area will also provide transit corridors through the mine as it develops L G Evenst, Inc Ragsdale Reservoirs February 6, 2020 34 EXHIBIT I/J SOILS 8i VEGETATION SOILS INFORMATION The following information was obtained from site observations and the basic soils and vegetation information found thru the USDA's National Soils information page and the Soil Survey of Weld County The soils information was downloaded from the USDA site and is made part of this application. Soil units are shown on the USDA map, reproduced on the next page. The photo map shows the surrounding vegetation features and soil types. As explained earlier in EXHIBITD-MININGPLAN, the mine site is located about 3.5 miles north of Fort Lupton and is separated into a western and eastern area, because the land is separate by U.S. Highway 85 and the Union Pacific Railroad. The western border of the western area of the mine site parallels the South Platte River The first two (2) mining Phases of the western area lie in the floodplain of the river, and the remaining western area lies east of the Platte Valley Canal . The entire eastern area of the mine site lies east of the UP Railroad, where there is a terrace deposit that is currently used as agricultural cropland. There are 11 soils types found on the mine site that will be disturbed by mining Under laying the topsoil is a layer of overburden varying from 1 to 3 feet deep and a layer of gravelly sand that is 12 to 50+ feet thick. There is adequate topsoil to salvage, so an average of 6-12 inches will be replaced on all areas needing seeding for reclamation The excess soils may be sold. The overburden will be used on -site to backfill areas that will not be developed as water storage areas. Some topsoil and overburden may be sold as fill material.

delineated on the detailed soil maps in a soil survey represent the soils or miscellaneous areas in the survey area The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas A map unit is identified and named according to the taxonomic classification of the dominant soils Within a taxonomic 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 38 Custom Soil Resource Report Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management These are called noncontrasting, or similar, components They may or may not be mentioned in a particular map unit description Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management These are called contrasting, or dissimilar, components They generally are in small areas and could not be mapped separately because of the scale used Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape The presence of minor components to 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 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 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 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 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 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 39 Custom Soil Resource Report 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 Such areas have little or no soil material and support little or no vegetation Rock outcrop is an example 40 Custom Soil Resource Report Weld County, Colorado, Southern Part 1—Altvan loam, 0 to 1 percent slopes Map Unit Setting

Adjacent to the permit area along the South Platte River bottom, there are trees, brush and grasses. This area will not be disturbed as it is outside the Affected Lands/Permit area The overall property appears to have had a long history of agricultural use as irrigated cropland The attached tables are from the USDA soil survey report and show the typical vegetation types for different soils found within and adjacent to the mine. Uncultivated Lands 1. Current cover percent is 45 to 65% 2. Topsoil depth on site averages 0 to 12 inches 3. Seeding dates recommended October 15 to May 1. 4.

Everist, Inc mining sites in Weld County, and was originally prepared by the Platte Valley NRCS office The seed will be drilled where possible and doubled if broadcast The non -cropland areas have no special or unique characteristics, and consist mostly of a weedy -grass covering Cultivated Lands The backfilled area will be vegetated with a grass seed mix or may return to their former use as cropland. The exact types of crops are not known at this time but will most likely be corn, winter wheat, cattle feed or alfalfa When backfilling is complete, and the areas are released from the DRMS permit, the landowners will determine what will be planted on these areas. Vegetation Information The following vegetation types were observed and mapped on the site. L G Evenst, Inc Ragsdale Reservoirs 70 May 5, 2020 EXHIBIT J VEGETATION INFORMATION (cont) Non Irrigated Cropland and/or Vacant Land - covers approximately 11 % (about 77 acres) Most of the acreage east of the Platteville Ditch, north of CR22 and areas surrounding the irrigated fields is rangeland Some wet soils are associated with the ditches or the irrigation return flow ditch on the western parcels. The vegetation consists of mostly grass, weeds, and some cactus The plant community is 80 to 85 percent grasses and 5 to 15 percent cactus and weeds. Grass species makeup 85% to 90%, by weight, of the non -cropland vegetation found on the site Irrigated cropland - covers about 76% (about 533 acres) Historically, these areas have been used as irrigated fields in which corn, winterwheat, sorghum, or other cash crops have been grown The landowner will continue to farm areas that are not being mined throughout the life of the mine The landowners determine what crops will be grown year to year and they will be responsible for planting the backfilled areas when backfilling and topsoiling is complete. Oil & Gas operations areas - cover approximately 1% (over 6 acres) These areas will not be disturbed by mining and have little or no vegetation of any value. It is mostly weeds with some sparse grass areas surrounding the roads and bare ground These areas will not be resoiled or seeded County Road ROWS. - this area covers approximately 0.5% (about 3 0 acres) This area will not be disturbed by mining. Farming Facilities - these areas cover approximately 2% (about 15 acres) They contain houses, barns, sheds, livestock pens, corrals, irrigation pumping areas and equipment parking/storage areas Vegetation on these areas is usually very sparse and consists of weedy patches and grass. Water areas - these areas are within the banks of the Platte Valley Canal, the Platteville Ditch and the Cannon Return Flow Ditch The water surface areas at this time cover approximately 1 % (about 10 Acres).

The RECLAMATION ACTIVITIES table below shows the various items needed to reclaim the initial 3 phases once full production is taking place in that area. In this scenario The first 4 tables are used in the Bond Cost Estimate but each Phase represents the total cost to reclaim that Phase less any activity that is not part of the Working Bond estimate for this time period in the mine. The Floating Table has the costs that will float from one Phase to the next as mining progresses The primary costs are the staging of the Bank Armoring in 1000 foot segments with a minimum of 2350 cubic yards of concrete rubble stockpiled within 500 feet of the placement area, the stripped area in front of the working face, yearly weed control and final grading of a 2600 foot long working face using a cut/fill method (5 65 cy/lft). No dewatering cost is included since we presume that the liner in Phase 1 will effectively seal the mined area, so no dewatering is needed. In Phase 1A, the slope will be mined 3h to lv so no underwater sloping will be needed and this Phase can be backfilled, without pumping the water, to a point 2 ft above the average ground water table No ground water will be exposed in Phase 3 while it is being used as the plant site area, so no slurry wall will be installed until mining is planned for that area. Phase 1 is the active mining area. The cost to reclaim would include all items shown in the Table for that Phase, less the total armoring. As mining progresses, the items in the Floating Costs table come into play There are 30 acres stripped in front of the working face that is 2600 ft long (5.65 yds/lft) cut/fill sloping). All other slopes will be finished and armoring installed as L G Evenst, Inc Ragsdale Reservoirs June 25, 2020 L-1 RECLAMATION COSTS (CONT) EXHIBIT L mining progresses to limit the amount of final sloping needed Resoiling and seeding would be required on 38.03 acres, 30 acres stripped and 8 03 bank slope reclamation The completed slurry wall is 7900 feet long at 38 ft deep, average No more than a 1000 foot section of bank armoring on the west bank will require placement at any time requiring 2 35 cy/lf of material (2350 cyds). A stockpile of armoring material will be maintained adjacent to the area where it is needed, so the only cost is for placement. The calculations for bonding the slurry wall liner in Phase 1 use the estimated length of the slurry wall in the effected Phases (Phase 1), times the average depth, which includes the bedrock key. The estimated unit cost is based on DRMS past bond calculation of $5.00/sq-ft with no reduction for construction, until the slurry wall is certified. No QA/QC number is included since the walls have been placed prior to mining beginning in any Phase Phase lA is being used as a settling/fresh water pond Bonding covers the cost of backfilling if it is needed. Material to complete backfilling in this phase will be stockpiled on the south end of Phase lA and North end of Phase 3 to reduce the haul distance. There are 15 88 acres of backfilling to fill to a level that is 2 feet above the existing ground water elevation. No side sloping will be required, so 647,680 yards of backfill material is needed for backfilling. No seeding is needed, as area will become cropland Phase 3 will be used as a processing plant and stockpiling area, potential drying pad for settling pond fines, overburden storage, topsoil storage and equipment parking areas Approximately 60 6 acres will be disturbed on this stage, and they would need to be resoiled (81,500 yards) and graded At this time, when the phase is being used as the plant site, the area could be reclaimed as cropland, so no seeding would be done until the farmer puts it back into production. Estimated concrete foundations to remove for processing plant is 200 yds of concrete. The slurry wall is not installed at this time since no ground water is exposed and mining has not started in this Phase, so no cost for the slurry wall is included L-2 L G Evenst, Inc Ragsdale Reservoirs June 25, 2020 RECLAMATION COSTS (CONT) EXHIBIT L The Equipment Used in the Estimate Is Scraper teams - 2 -Cat 627G scraper, D9R Dozer, 140H grader & water truck - Resoiling & backfilling • Grader - Cat 140H - seedbed prep and ripping plant site • Loader — Cat 688 — armoring placement • Dozers - 2 - Cat D9R - cut/fill working face sloping • Seeding team - standard farm tractor and pull behind drill, and crimping disk attachment Unit Costs Used In Estimate Task -Description 001 - Revegetation - per acre 002 - Cat 627G and scraper team Replace Topsoil - per cubic yard Haul distance 900 feet or less 003 - Cat 140H blade Rip seed beds per acre 004 - Cat 140H blade Grade and shape per acre 005 - Construct slurry wall liner per foot -depth 06 - Cat 988 Loader Place armoring materials per yard Haul distance less than 500 ft 07 - Cat D -9R dozer Cut/Fill per cubic yard Push distance less than 120 feet 008 - Cat 627G scraper team Backfill Phase IA Haul distance 900 feet of less 009- Mob/demob - Haul distance 5.0 miles average speed 50 mph 010 - Concrete demo per yard @ $7 00/yd 011 - Weed Control per year 012 - Secondary seeding per acre Direct Cost 850 00 $0 824 $99 11 $93 71 $5 00 $0 72 $0 637 $0 824 $6,406 48 $7 00 $5,000 00 $212 50 L G Evenst, Inc Ragsdale Reservoirs L-3 June 25, 2020 L.G.

In 2004, the CDA updated weed management laws to create the A, B and C species lists. See current list on CDA's website at: https://www.colorado.gov/pacific/agconservation/noxious-weed-species (updated March -2017). List A Species are designated by the CDA for eradication. List B Species - CDA and local government develops and implements state noxious weed management plans designed to stop the continued spread of these species. List C Species are species for which CDA has left it up to the local governments to address if they choose to. The List C species are wide spread throughout the State of Colorado. N oxious Weeds commonly found on mine sites and agricultural lands in Weld County List B Canada Thistle Dalmatian toadflax Leafy spurge Russian Olive (tree) Salt Cedar/Tamarisk (bush/tree) List C Downy Brome/Cheat Grass Field bindweed Weed Control/Management during Mining and Reclamation The operator shall monitor affected and reclaimed lands for noxious weed infestations. If weed infestation occurs on the permitted land, the operator will perform a combination of the following practical operating practices and weed control methods during the life of the mine, until fully reclaimed/released. - Minimize disturbed areas, disturbing only the acreage to be mined in the upcoming field season, and limiting the roads and equipment storage areas Reclaim affected areas as soon as possible - topsoil and vegetate with a native grass mix Minimize or eliminate wetted soils, create positive drainage at all times Vegetate topsoil and overburden stockpiles, and other disturbed areas, with a native grass mix to control erosion and weed growth Inspections will be will be conducted in early Spring and Fall to determine if weed spraying is needed before the native plants become active. Weeds will be sprayed with most effective chemicals for the species (using county and contractor recommendations - see>Weld>County>specific>recommendations>below) Throughout the growing season, weeds will be mechanically controlled by various methods (mowing, pulling, dozing, chop -down, and other removal) Estimated Cost of Weed Control $5,000 - $10,000 per year 105 CANNON-DRMS-WeedPlan-Jan2020.doc Cannon Land Company — Ragsdale Reservoirs WEED CONTROL PLAN Weld County Weed Management - Techniques and timing for Weed Species Listed below Afrom>Tina>Booton7>Weed>Division>SupervisorMeld>County>Public>Works7>EugFGH I JK> Downy Brome/Cheatgrass Esplanade at 5 oz/acre in July/early August as a pre -emergent treatment Treatments will be made using both broadcast spray on the large patches and handgun treatments of the small patches Esplanade has shown to provide two years' worth of control of cheatgrass whose seed longevity is fairly short During these two years of cheatgrass suppression, the surrounding vegetation on the sites in the research plots has filled in to out compete the cheatgrass With as much other vegetation that is in the area, it is believed that this will be the similar case at Lehr A spring inspection in February/March (as soon as snow load is gone and the site is accessible) will be conducted to determine if any other treatments are needed before the native plants become active Field bindweed, Canada thistle and Dalmatian toadflax Tordon at 32 oz/acre with an MSO surfactant at 32 oz/100 gallons will be used to treat these species in September/October of 2016 These patches will be treated by handgun work to limit any impact to surrounding forbs A spring inspection in May/June will be conducted to see if a spring treatment is necessary or another fall treatment ins CANNON-DRMS-WeedPlan-Jan2020 doc PUBLIC NOTICE PUBLISHED NOTICE OF APPLICATION FILING FOR A REGULAR (112) CONSTRUCTION MATERIALS RECLAMATION PERMIT L G Everist, Incorporated has filed an application to obtain a Recla- mation Permit with the Colorado Mined Land Reclamation Board under the provisions of the Colorado Mined Land Reclamation Act for the extrac- tion of construction materials This application is for 643 30 acres to be included in the permit area The mine is known as Ragsdale Reservoirs (Permit #M-2020-007) and is located in parts of Sections 7, 8, 17, 18, and 19, all within Township 2 North, Range 66 West, 6th Principal Meridian, Weld County, Colorado The proposed date of commencement for the mine is 2020 and the pro- posed date of completion 2040 The proposed future use of the land is developed water storage Additional information and the tentative decision date may be obtained from the Division of Reclamation, Mining & Safety,1313 Sherman St , Suite 215, Denver, CO 80203 (303) 866-3567, or at the Weld County Clerk to the Board's Office at 1150 "O" Street Greeley, Colorado 80631, or the above -named applicant Comments must be in writing and must be received by the Division of Minerals and Geology by 4 00 p m on , 2020 Please note that comments related to noise, truck traffic, hours of operation, visual impacts, effects on property values and other social or economic concerns are Issues not subject to this Office's jurisdiction These subjects and similar ones, are typically addressed by your local governments, rather that the Division of Reclamation, Mining & Safety or the Mined Land Reclamation Board L G Everist, Inc Henderson, Colorado First Publication Second Publication Third Publication Last Publication Published in L G Evenst, Inc Ragsdale Reservoirs February 6, 2020 107 NOTICE This site is the location of a proposed construction materials opera- tion known as the Ragsdale Reservoirs L G Everist, Inc, whose ad- dress and phone number is 7321 E 88th Ave, Suite 200, Henderson, CO 80640, (303) 287-9606, has applied for a Regular 112 Reclamation Per- mit with the Colorado Mined Land Reclamation Board The total permit area will be 703 95 acres Anyone wishing to comment on the applica- tion may view the application at the Weld County Clerk to the Board, Board of County Commissioners office, 1150 "O" Street, Greeley, Colo- rado 80631 , and should send comments prior to the end of the public comment period to the Division of Reclamation, Mining & Safety, 1313 Sherman St, Room 215, Denver, CO 80203 Certification I, 7 'L'cT ��.a , c. , hereby certify that I posted a sign contain- ing the above notice for the proposed permit area known as the Ragsdale Reservoirs, on JA uc/A aY rce , 2020 FsleaL -eJA&- -Zazo SIGNATURE DATE L G Evenst Inc Ragsdale Reservoirs January 27 2020 108 L.G. Everist, Inc Ragsdale Reservoirs M-2002-007 June 26, 2020 BANK ARMORING PLAN This bank protection plan is presented to explain the bank armoring proposed for reservoir bank protection in Phase 1 and Phase 2 that run parallel to the South Platte River channel Only the reservoir side armoring is being proposed since the river bank lies 150 to 250 feet west of the top of the slope of the permit area. The attached Figure 1 shows the cross-section of the area discussed below and details of the armoring to protect the banks along the west side of Phase 1 The west and south banks in Phase 2 will also be armored using this plan The Reclamation Plan Maps have been revised to show the location of the areas to be armored in the mine The armor is intended to protect the reservoir banks should a 100 -year flood event occur after an area has been reclaimed The armoring will be covered with a 6-10 inch layer of growth medium and seeded with the approved seed mix The toe of the slope armoring will be at least 5 feet below the thalweg of the adjacent riverbed. The base of the armoring will average 10 feet below the existing ground surface at the mine The 100 -year Floodplain information has been included on all of the Map Exhibits in the Reclamation Packet Armoring material will be recycled concrete fragments with surface rebar removed, so that it meets the definition of Inert Materials The concrete will be sized 9 to 15 inches averaging 12 inches. Fines will be mixed in to fill voids This size material will have a Safety Factor of 1 26. See Bank Armoring Calculation page following this text The operator will keep enough material stored on the mine to complete armoring needed on any area where sloping is being completed and is ready for armoring At a minimum, 2,350 cubic yards will be stockpiled on the mine for use in armoring This is enough to armor a minimum of 1,000 feet of excavation bank. At no time will there be more than 1,000 feet of armoring needing to be placed The stockpile of armoring material will be placed parallel to the water flow so it will not interfere with flows in the flood plain if flooding occurs It will be within the setback between the permit boundary and the mine highwall so it is close to the area where it will be placed Ellicott Sand 8 Gravel LLC Bank Armoring Plan Page 2 (June 26, 2020) Reservoir Bank Armoring. Armoring will be placed inside of the mined areas adjacent to the South Platte River channel (Phases 1 and 2) and along the downstream side of the lateral berm between those areas. The armoring will be placed on the slopes starting from the existing ground surface elevation The toe of the armoring will be a minimum of 5 feet below the river thalweg, have a 3h to lv slope and will be 2 feet or more thick This is approximately 2.35 cyd/lft along the excavation bank slopes Once sloping begins, the armoring will be installed on 1,000 foot sections until completed This will leave an armored face along the top of the bank and the slope into the reservoir that is 35 feet wide Supplied supporting documents Figure 1 - Bank Protection Plan cross section (revised) Safety factor calculation page BANK ARMORING PLAN FIGURE 1 PERMZT '-'-NE 6 ft TOP OF S1-OPE a A channell thalweg a a 30 ft, °a ' ° 4 °2 35 cyd/lft' _ 2 ft a IIII °a ° ° , I 1 I I 4° a Ills I I —I I I I° I a . a . a Il11 1111 -50 -45 -30 -20 -10 0 10 20 TYPICAL CREEK BERM ARMORING NO SCALE NOTES 1 BANK ARMORING SHOWN ON RECLAMATION MAPS IS APPROXIMATE LOCATION ACTUAL LOCATION WILL DEPEND ON LOCATION OF TOP OF SLOPE AT THE TIME IT IS INSTALLED 2 MATERIAL USED FOR ARMORING WILL BE WELL AGED BROKE CONCRETE THAT HAS ALL EXPOSED SURFACE REBAR REMOVED AT A MINIMUM 2,350 CUBIC YARDS WILL BE STOCKPILED ON THE MINE FOR USE IN ARMORING THIS IS ENOUGH TO ARMOR MATERIAL TO ARMOR A MINIMUM OF 1000 FEET OF EXCAVATION BANK 3 STOCKPILES OF ARMORING MATERIAL WILL BE PLACED PARALLEL TO THE RIVERBANK SO IT WILL NOT INTERFERE WITH FLOWS IN THE FLOOD PLAIN THE STOCKPILES WILL BE PLACED BETWEEN THE PERMIT LINE AND THE TOP OF SLOPE WITHIN 500 FEET TO THE AREA WHERE IT WILL BE PLACED JUN 25 2020 - 16 24 43 IIII IIII 30 40 10', H IL I H W I rill -10' 50 4 BANK ALONG THE EXCAVATED AREA WILL ARMORED FROM THE EXISTING SURFACE TO A POINT AT LEAST 5 FEET BELOW THE CHANNEL THALWEG 5 THE SIZE OF THE MATERIAL WILL FALL IN THE RANGE OF 9 TO 15 INCHES AVERAGING 12 INCHES AS DISCUSSED IN THE BANK ARMORING PLAN AND WILL BE PLACED BELOW GRADE 6 THE ARMORING WILL BE COVERED WITH A 6 INCH LAYER OF GROWTH MEDIUM AND SEEDED WITH THE APPROVED SEED MIX L G Everest, Inc.

Colorado 80503 303-651-1468 schnabel-eng.com I deereault.com June 26, 2020 Response to DRMS Comments on Cannon Lands Slope Stability L.G. Everist Cannon Lands DA201041.00 This memorandum is in response to comments received from the Colorado Division of Reclamation, Mining and Safety (DRMS) on June19, 2020 regarding Ragsdale Reservoirs, DRMS File No. M-2020-007, also known as Cannon Lands. 1. Factor of Safety Selection In the Cannon Lands Slope Stability Technical Memorandum by Deere & Ault dated June 5, 2020, data was presented that made the case that based on general soil index testing properties (gradation, liquid limit and plasticity index), site proximity (one mile away) and similar subsurface geologic profiles', soil and rock strength parameters from the Fort Lupton Pit could be used at Cannon Lands. The case was made that extensive testing at the Fort Lupton Pit, which resulted in the selection of conservative soil and bedrock strength parameters for slope stability analyses, made it appropriate to use the lower Factor of Safety from MLRB Policy No. 30. The comment states that, "the DRMS cannot accept the submitted analyses as demonstrating compliance with MLRB Policy No. 30," and outlines two options; A and B. Both options are to perform a site -specific geotechnical investigation. In response we are providing strength test results of the Laramie bedrock from the Fort Lupton site, and other sites in the front range also situated on the Laramie bedrock. The Cannon Lands site is located within the Laramie Formation. We are providing bedrock testing data because the strength parameters of the bedrock control the slope stability analyses. Often the laboratory strength values for claystone bedrock are much higher than actual empirical values observed in the field. There are three different types of strength of a claystone or stiff fissured clay. These are peak strength, fully softened strength and residual strength (remaining strength after significant shearing displacement). Peak strength is associated with undisturbed claystone. Fully softened strength develops after claystone is disturbed by excavation and wetting/drying cycles. The peak strength degrades over time, years to decades, from this disturbance until fully softened strength is reached, and cohesion is reduced to zero. We chose to use fully softened strength values for the Laramie claystone as a conservative yet realistic representation of bedrock behavior. One method commonly used for obtaining fully softened strength is to take the remolded strength. In 2010 as part of slope design work at the Fort Lupton Pit triaxial strength tests were performed on three samples remolded to approximately 95 ' Based on regional geologic mapping (Colton, 1978), the near surface bedrock in the project area consists of the Upper Cretaceous Age Laramie Formation. The bedrock is overlain by upper Pleistocene and Holocene (Quaternary age) gravel deposits associated with the South Platte River. L G Evenst Response to DRMS Comments on Cannon Lands Slope Stability percent of Standard Proctor density at the optimum moisture content The tests were performed as consolidated, undrained tests with pore pressure measurements We interpreted the test results using Mohr circle plots and different failure criteria, including maximum principal stress ratio, maximum deviator stress, and 10 percent strain Depending on the criteria, interpreted effective cohesion ranges from 150 to 750 pounds per square foot and the effective friction angle ranges from 18 5 to 30 degrees The lab data from this testing is attached to this memorandum Earlier testing was done on the Laramie bedrock at the Fort Lupton Pit in 2009 in association with design of a pump station, interconnect tunnels, and discharge conduit when several mined cells were converted to water storage reservoirs This data is also attached The tnaxial test indicated an effective cohesion ranging from 150 to 750 pounds per square foot, and an effective friction angle ranging from 18 5 to 30 degrees depending on the failure criteria used for analyzing the raw data The best method for obtaining the fully softened shear strength is to utilize the geometry and pore water pressures of a field failure, set the factor of safety at 1 0, and back -calculate the shear strength A field failure serves as a large-scale test that provides more accurate results than a small laboratory test This back -calculation analysis was done for a slide on an inner berm (cell divider) of Women Creek Reservoir that occurred in October of 2011 This reservoir is located on Laramie bedrock Geometry of the slide was measured in the field and the water levels were known from the nearby wells The resulting back - calculated shear strength for the bedrock was an effective cohesion of zero and effective friction angle ranging from 18 to 21 degrees This correlates well with analyses we have performed on other dams in the Laramie Formation, such as Standley Lake and Great Western Reservoir Bedrock strength testing for both Standley Lake and Great Western are also attached With the supplied strength test data supporting that the strength parameters we have selected (effective friction angle of 18 and effective cohesion of 0 for fully softened bedrock and 500 for fresh bedrock) are conservative for Laramie bedrock at Cannon Lands, we stand by the use of the lower factors of safety from MLRB Policy No 30 (1 3 for static and 1 15 for seismic) We have demonstrated through industry standard geotechnical index properties, published geologic mapping and physical proximity that the sites can and should be considered geologically and geotechnically the same Therefore, the data supplied in this and the previous memorandum are sufficient to provide a high degree of confidence in the strength parameters used in the Cannon Lands slope stability analyses We propose no further testing is necessary The presented slope stability analyses are a conservative yet realistic representation of slope stability for the Cannon Lands site, based on actual site conditions Additional testing of the Laramie bedrock will, in our professional opinion and past experience, result in higher strength parameters than we are currently using 2 Seismic Evaluation The 2014 USGS National Seismic Hazard Map is attached The highest and lowest hazard zone correlate to the two -percent probability of exceedance in 50 -year map of peak ground acceleration, which is also attached This map shows peak acceleration as a fraction of standard gravity Faint contours of peak acceleration are visible on this map We have obtained the contours from the USGS as a shape file When the shape file is loaded into GIS a more detailed and interactive view of the contours is available On the attached detailed map, the City of Fort Lupton is shown as a large yellow dot Cannon Lands is located just north of Fort Lupton, equal distance between the 8 and 10 contours (or 0 08 and 0 10 g) We have selected 0 09 g based on this detailed map We chose 2 percent in 50 -year because it is the longest earthquake recurrence interval available, and thus represents the most conservative analysis Project DA201041 00 6/25/2020 Page 2 Deere & Ault, a Schnabel Engmeenng Company FORT LUPTON REMOLDED I Shear Stress, ksf O 0) 0) CD Total Effective C, ksf 0 39 0 21 "" (I), deg 11 6 25 1 "- Tan( ) 020 047 ..�....
