Increase acreage by adding 8.92 acres along the west side, and by adding the 25.38 acres of Phase 2A into Phase 2 (changesdue to oil and gas), for a new total of 189.83 acres • Phase 3 - Increase acreage by adding 7,90 acres for a conveyor crossing over the transportation corridor that separates Phase 3 and Phase &„ for a new total area of 81.20 acres, • Underdrain rdra i n - Revise reclamation plan to include the underdrain bui It between Phase 11 and Phase • Revise the reclamation practices around the reservoir perimeters to allow for a band of gravel to be left between the high water line and the slurry wall_ The methods described and approved in the original mining and reclamation plans will remain unchanged unless discussed in this texts e have included all exhibits for continuity of the file and have marked those Exhibits with NO' H!N'E if they are the same as originally submitted* ed* Were appropriate, the PAININGAND RECLAMATIONPLANS AND TIMETABLES have been re iced to reflect the proposed changes. The mends nt will follow isALRB Rule 1.8 and Colorado Revised Statutes, 199Z Section 34-32-112(8). EXPANSION- Phase 1 and Phase 2 - are being increased by a total of 18072 acres the along the west side in order to address the underdrain installation and add the associated permit boundary e xtension* When reviewing the existing permit for this amendment, the operator decided that moving the west permit boundary of P hases 1 and 2 farther to the west would prevent any additional disturbance outside the permit area* The western permit boundary will now generally follow the west side of an existing agricultural access road, which is elevateds Portions of this additional permit acreage may be disturbed, and if so will be r ve trated. Phase 2 is also expanding due to incorporating Phase 2A into its total area* The large gasline that previously divided Phase LiG, Everist, line, Ragsdale Reservoirs Revised February i i n 2025 EXHIBIT D MINING PLAN (CoNT) 2 and 2A was rerouted to the north side of Phase 2A, which allows for combining the two phases into one mining phase, and then to be reclaimed as one reservoir, This does not significantly affect the Mining or Reclamation Plans, and it actually reduces reclamation since there is no Phase 2A to bac fill f Phase 3 a Increase acreage by adding 790 acres for a conveyor crossing over the transportation corridor that separates Phase 3 and Phase 4 An existing dirt road will be used for access to the area*_ As the mine has developed, it has been decided the best way to transport raw material from the eastern properties of the mine (located on the east side of US Highway 85) to the Plant Site on the west side of HWY 85 is v i,a an elevated conveyor system, A 7_90 acre conveyor corridor shall be added between Phases and 4, on properties owned by Cannon Land Company; There are two Right -of -Ways (ROWS) crossing the Cannon properties, which are held by the Union Pacific Railroad (UPRR) and Colorado Department of Transportation (COOT) for HWY 85, An elevated conveyor system will be built to spin the ROWs* No parts of the structure will be placed in the Rights of Ways and L*G* Everist, Inc (LGE) ) is working with both ROW. owners to get }T� _.

N - Revise reclamation plan to include the underdrain built between Phase 1 and Phase 2, which was installed in the summer of 2024. The underdrain is shown on all amended Map Exhibits. The underdrain starts in two places - along the southeast side of Phase 21 and along the northeast side of Phase 1.. The two sections connect and the underdrain continues between the north slurry wall of Phase 1 and the south slurry wall of Phase * The outlet of the underdrain is past the west side of the phases, near the river* The outlet's location was what resulted in a violation due to a small area of disturbance. outside the existing western permit line._. The underdrain design and hydrologic evaluation information was ubmitted to the Division during. the permit investigation and is included in the APPENDIX. The underdrain maintains the hydrologic balance and maintains the groundwater elevation outside the slurry wall to its historic levels, by allowing the groundwater to seep into and La -E rase:, Inc, Ragsdale Reservoirs Revised February VII , 2025 7 EXHIBIT D MINING PLAN (CoNT) through the and rdra, n... There are clean out and inspection hatches located on the surface above the underdrain pipe at regular intervals to facilitate maintenance by the reservoir owners (Cannon Land Co.). RESERVOIR RECLAMATION CHANGE E- Revise the reclamation practices around the reservoir perimeters to allow for a band of gravel to be left between the high water line and the slurry wall. The ✓ evised reclamation practice is to leave a unerevegetated gravel band from the highwater line to the slurry walla The reservoir access road will also be in these areas since no recoiling or vegetation will be done. No soil cover will be put on the armored areas but the voids between the riprap will be filled w ith natural pit run material. On the areas around the reservoirs, from the slurry wall o ut, any disturbed area will be resoiled and seeded as currently approved. L.G.

The eastern area will have up to eight () mining areas, of which five (5) areas will become reservoirs and 3 areas w ill be backfilled and reclaimed as ro lan .. Mining in Phases 1,2,3,4, 5 & will be mined after the slurry walls are completed around them. Phases IA, 4A, 48, and SA will be dewatered d during mining so they can be mined dry. Dewatering will continue until mining ends in each of the backfill phases* The area being permitted and much of the surrounding areas has historically been used as cropland (irrigated and n on -irrigated), and vacant land. This site lies near the South P latte River, so it contains an alluvial gravel deposit in the western area, which extends into a large terrace of gravel in the e astern area* CURRENT CONDITIONS Large portions of the lands to be permitted are currently operated ed as irrigated farm land, by.

L MINING PLAN MAP EXHIBIT CsAI (_WINING PLAN N MAP shows the approximate direction of mining as it progresses across the site* The plan is for having 350 acres of maximum disturbance, of which the bonded amount may be less, due to areas that lie below the high water line of a reservoir that has all slope grading completed* This will allow for flexibility during mine development, rather than trying to limit the disturbance to small areas. The 350 acre will include areas that are stripped, partially mined, partially reclaimed, the Plant Site and material stockpile areas and future reservoir areas.

Mining began in this area and is working west and north. Side slopes are being constructed as mining progresses, so only the working face area would need to be shaped, and 100 acres or less would need to be resoiled, if mining ended at this time* Phase 3 is the active Plant Site, equipment storage and stockpile area and will remain as such for the life of the mine.

The methods discussed below will fit each option unless otherwise stated. Technical Revisions will be filed when needed to incorporate various items from Option B. As stated above, most of the Option B changes are related to oil and gas facility relocations and removals. Other possible Option B changes could occur if the landowners want to start development of facilities related to t heir developed water storage in a reservoir phase such as pump h ouses, inlet/outlet structures, rip rap and don't want to wait for DRMS permit acreage releases: In this optional case, L.G.

As mentioned above, the proposed mining sequence may change due to unforeseen circumstances such as market conditions, variations in the natural deposit, agreement restrictions with structure owners, etc. At this time, the plan is to mine them sequentially from 1 thru 6 as shown on the maps* The exception t o this sequence is Phase 3, which will be mined last if material from the eastern Phases can be conveyed across the railroad and HWY 85. The smaller Phases 4A, 4B, and SA will be mined prior to, or in conjunction with, mining beginning in the corresponding larger reservoir phases (Phases 4, 5, 6) .in order to provide areas for disposal of excess overburden and processing fines from those areas* Sight berms will be constructed along the Railroad ROW on the west sides of Phase 4, 42), 5 and 6, similar to the sight berm construction 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 50 acre area will be stripped and periodically as mining progresses it will be extended so there may be as much as 100 acres needing resoiii.ng at any one time as each Phase is mined. The topsoil needed for resoiling l ing the above water areas will be separated from the overburden and stored around the mining area for use in reclamation* Once enough t opsoil is salvaged to re gal the above water disturbed areas with an average of 6 12 inches, the rest may be sold..

The clean out and inspection hatches located on the drain pipe will remain to facilitate maintenance of the drain by the reservoir owners (Cannon Land Co.). RESERVOIR RECLAMATION CHANGE a The change to the reclamation of the ✓ eservoir perimeters is to change the reclamation practice of ✓ esoiling and revegetation tation on the land between the high water line and the slurry wall. Instead, gravel. will be placed in the area from the high water line to the slurry wall. The reservoir access road will also he in these areas since no resoiling or vegetation will be done.

The uses are, irrigated crop areas; non -irrigated pasture; ditch and return flow corridors; and also oil/gas operations areas with some high capacity a pipeline . O ' .r 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 s 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 it h, the Platte Valley Canal and the P latteville 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 EXHIBITS I J will not match the actual current vegetation since the practice for the agricultural activities are that crops are rotated from year to year. RE L O N PL. N FOR RESERVOIR AREAS This section covers reclamation on the developed water storage reservoirs in Phases 1 thru 64 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 iv slope of natural, undisturbed materials will need no other ✓ eclamation except minor grading to dress the slope. On the armored areas a dirty sand and gravel (unprocessed) will be spread over the armoring to fill most of the large voids, . Since the perimeter of the reservoirs will be mined to their f inal (3H to 1V) slopes, only minor amounts of slope work will be n ecessary 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 imated to be at the lowest crest elevation around any en reservoir* The t emporary topsoil stockpiles in the various mining phases will be available for reclamation needy When grading and shaping is completed on the section of ✓ eservoir banks and slopes inside the slurry walls, reclamation L G, Everist, Inc, Ragsdale Reservoirs Revised February i 1, 25 23 EXHIBIT E RECLAMATION MATION Pu leo ,, T) �p�1•IR{• .. will b e complete for that area ■ For r areas outside the slurry walls, they will be rescued and then seeded during he next. seasonal planting window* The MAP (EXHIBIT F RECLAMATION PLAN MAP OPTION A and OPTION: B show the sloping plan. and how the area . around the ✓ eservoirs will be handled in this plan*. The cross section on the Reclamation Maps, show the relationship between the gravel band, reservoir slope and revegetated areas* 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 areas or access roadways, will have an average of 6 12 inches of topsoil placed and prepped for seeding. All top soiled areas will be seeded with t he seed mix described in this plan, and effective weed control measures ill. be implemented until the Phase is released from the permit area. The applicant requests that the establishment of full revegetation fi t at ion ill not be required for permit acreage release if "reasonable assurance" that the development for the approved post mining land suse will continue prior to establishing permanent vegetation. An example of "reasonable assurance" is a letter from the landowner (Cannon Land Company) stating they accept the reclamation "as is" and they. plan to continue development of said reservoir and will be re disturbing some areas to install developed water storage reservoir operation facilities As mentioned in the mining Plan, if the reservoir phase acreage is not released from the DRMS erm.it , and the landowner constructs developed water storage facilities that are n ot in this eclamation Plan, then L.G. Everist will file a Technical Revision to incorporate the changes prior to asking for ✓ elease of the area* .R L MA TI PLAN FOR . KFIL L AREAS This section covers reclamation on the developed water storage reservoirs in Phase 1A, 4A, 4B, AND SA. The 4 areas have commercial deposits of gravel but are too small or too shallow to develop as ater storage reservoirs* 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 i l l in and so they would not have to be graded if backfilling does not fill t hem completely. The backfill i l l material will be excess overburden, and site generated inert materials, including the fines generated during processing of the r a w sand and gravel. At any given time, backfilling may be taking place on 2 or more P hases as shown on the MAP EXHIBIT C-1 a MINING PLAN . AP .

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 lank ing by the landowner. 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 re get tion necessary.

GENERAL DISCUSSION There are sufficient amounts of topsoil on the site so the disturbed areas between the slurry wall and the permit line can be r lolled 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 reve etation. In Phase 1 and 2, a topsoil berm is being placed along the o utside edge of the slurry wall so when reclamation begins it can be r ad over the area disturbed adjacent to the slurry wail As discussed in other parts of the Reclamation Plan the area from the slurry wall in, to the highwater ater line will be a gravel bands The existing soils on the property have been capable of producing healthy crops and grasses and are expected to wark 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 MRCS soil survey web pages A copy o f that report is in EXHISITIANDJand describes the current soils and vegetation on the properties. As outlined in the EXHIBIT iD MINING PL. NI, approximately 510 to 514 acres of the permitted area will be disturbed as a result of mining activities, depending on Option A or B. The plan calls for bonding to have 350 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 i. l l Phases and any one time mining progresses across the property some parts of the property w ill remain undisturbed while other areas will be either, stripped, mined, partially reclaimed or totally reclaimed* The MAPEXHIBITC1 MININGPLANMAPshows how the pit will look as if all area have been mined and the slopes have been graded.

SEEDBED PREPARATION When mining on an area is complete or there is room to egin ✓ eclamation, any compacted areas disturbed 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 R or a seeding/revegetation _rev get at ion 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 siring (November through May) The time of planting will be controlled by when the resoiled areas are read. for planting. If fall planting is convenient, the seeding will be done before the first freeze (about . the time ' i 1l i e r wilea t is planted). If spring planting is called for, it will be done in March or April, weather permitting, after t h e last frost. Both periods assure there will adequate residual ground moisture available for the n ewly planted seeds. For areas that will be planted with crops, the crops planted will be determined by the Landowners or farmers w ho handle crop planting now. GAUSSES The following approved seed mix was developed by the NRCS o ffice in Brighton many years ago and is used on all Le . Everi t raining operations in Weld County. It has proven to be very ✓ eliable. This mix will place approximately 4142 seeds per pound per sq-ft as rescra ed by the NRCS planting guidelines. If the seed is broadcast, the amours will be doubled and spread on a rough surfacew 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 ed areas when reclamation is complete. No trees will be planted, because they are not compatible w ith reservoir development as their root systems affect the liners* It is expected some natural invasion from adjoining areas ill occur* �.. .

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 n ot necessarily. desirable or possible, o we will be using stronger controls on the noxious weeds and controlling the rest as needed...

Based on regional groundwater studies and the experience gained b. L..L.G. Everist, Inc* during numerous previous permit applications they have found that slurry. wail liners mitigate any impacts to groundwater on nearby areas surrounding a lined reservoir* Additionally, the ditches, river and streams lying acme 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 Trarsi er 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 year period from October 2019 to September 2021 will be used as the baseline for triggering mitigation actions* Mining started in Phase lei.,, which is the first unlined area The depth to ground water in this Phase - according to the data collected - is an average f 17.5 feet below the surface, so shallow mining work can be done without exposing round .1t er This gave time to collect the 5 quarters of data before any potential impacts could occur to adjoining wells* The baseline data needed for the areas was in place before installation of the slurry walls. There are outside influences not caused by any mining operations of L.G.

( ON!T) influence the groundwater levels and impact the baseline range and trigger points 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. An Underdrain was installed along the northeast side of P hase 1 and the southeast side of Phase 2 at the request of the Landowners The underdrain is shown on all amended Map Exhibits. The underdrain starts in two places - along the southeast side of Phase 2, and along the northeast side of Phase 1. The two sections connect and the underdrain continues between the north slurry wail of Phase 1 and the south slurry wall of Phase . The outlet of the underdrain is past the west side of the phases, near the river. The underdrain design and hydrologic evaluation information is included in the APPENDIX. The underdrain maintains the hydrologic balance and maintains the groundwater elevation outside the slurry wall at its historic levels, by allowing the groundwater to seep into and through the underdrain. There are clean out and inspection hatches located on the surface above the underdrain pipe at regular intervals to facilitate maintenance by t he reservoir owners (Cannon LandCo.). 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 influ nce , including, climate, re i itat ion, irrigation, other pumping rights, and much more. LisGs Everist, I nc' s ... experience other mines in the South P latte 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 -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* 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 . Everist, line, Ragsdale Reservoirs Revised February i i , 2025 37 EXHIBIT G WATER INFORMATION ( oN!T) enough unlined areas crossing thru the lined reservoirs to allow for some increase without impacting surface features. In the eastern. area groundwater averages 12feet below the surface, there are numerous, ga.slines 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 e vaporation 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 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 r 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* CARS shall be notified within two business days o f the complaint and the proposed initial steps for the evaluation of the complaint* A written report will be submitted to DDS within 30 days detailing the information collected during the investigation of the complaint,_ and proposed mitigation activity, if required Potenti a Water Resource Impacts � � pacts 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 EXHIE T 0 MINING PLAN) TABLE G-1 is a list of 16 wells from the ffic of the tat Engineer's files, and whose permit locations are within 200 feet o f the permit area* (Note: all permit locations are not always accurate, especially for older wellso) The wells highlighted in La Everist, Inc, Ragsdale Reservoirs Revised February i i , 2025 31 EXHIBIT G WATER INFORMATION!

HEBIT H SlanificaAt WiidiltO_ROSOurCe. Much of the land to be permitted is used as an active farm with many areas d for crop production. The species of wildlife found in the area around the property are those typically found on actively farmed areas such as turkeys, song. birds, and duc.k and geese, as well as mammals such as skunks, mice, deer, fox, and coyotes. The larger game animals such as deer, fox, and coyotes are commonly seen along the South. Platte River or ;n cultivated fields after harvest. In areas surrounding the water features crossing the site, there may be reptiles and amphibians. The smaller mammals and wildlife are usually ly- found around the perimeters of the active crop lands and farm buildings wherever erever protective vegetation exists. No raptor nests were observed on the permit area however, an: old_ eagles nest was observed. on an adjoining owners property that is north. of the permit area. We are aware of a. winter roost for eagles located along the South Platte River to the north of the permit area. Since the primary roost activity and nest are not in the permit area they will not be disturbed by mining. There is no nest identified on the Colorado Parks and Wildlife life (CPW) web site. Seasonal Use Many of the mammals that may potentially be encountered on the mine are expected to be year-round residents, o r, will come and go depending on their mobility. The deer, fox and coyote are not movement -restricted and tend to travel through many properties as part of their natural daily routine covering several square miles. The water fowl, raptors and other birds may use the property year-round with some migrating in. the spring and fall. Shorebirds may use the site during the spring, summer, and fall for feeding r resting during migration. The smaller mammals may. be displaced initially, but with the amount of surrounding area that will not be. disturbed they will find places in and around the active mining areas. Any amphibian and reptile species that may be present on the site could be year-round residents, since they would likely stay in the areas around the site's water features (ditch setbacks) which wiLl not be disturbed by mining. ThreatenedLand r c - , . r ti cal Ha bi t a t There are no threatened or endangered species on the permit area to our knowledge. A site review indicates there is no habitat f o r the Preble's ' s meadow. jumping mouse on the permit area. Areas L.G. Everist1 Inc. Ragsdale Reservoirs 44 Revised February 11, 2025 EXHIBIT H WILDLIFE iNFORMATION M1ATIONI (coNfi near the irrigation ditches within the site have steep sides and do n ot have vegetative cover that is characteristic of Prebl r s habitat. In addition, the only possible habitat on the permit area for Ute e ladies -tresses orchids would be the area between the Cannon Return Flow Ditch ch and the Platte Valley Canal and this area is not being mined. Bald Eagles have been removed from the Threatened and Endangered list however they fall under the Migratory ratorBird 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 on the north end of Phase 2. During the time prior to mining the north part of Phase 2 an 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. Update - 2025 - the old eagles nest noted was blown out of the tree recently. and destroyed The eagles have built the nest approximately 440 feet to the north of the permit line heaving most of Phase 2 out side the setback area 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 t ake the appropriate actions to minimize disturbance ✓ oost area fl the nest or Proiect Effects to Wildlife Existing wildlife in. the area. is not expected to be significantly impacted by. mining at this ite . 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 t m a Haul road peelimits will be limited to 15 MPH or less. There may be some displacement o f smaller birds and mammals during active mining operations in a phase, but once a reservoir is developed it will increase the habitat for shorebirds and water fowl. The revs stated areas may. become habitat for small mammals. There will be no mining within the river corridor area, t herefore leaving a transit area for larger wildlife and scavengers along the river to bypass the mining area. The ditch SOW' s and irrigation return flow area will also provide transit corridors t hrough the mine as it develops. Everist line.

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 taxan ornic. 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 grope rties 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 ap unit is made up of the sods or miscellaneous areas for which it is named andsome minor components that belong to taxonomic classes other than those of the major soils. 49 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, astin , or similar, components. They may or may riot 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 ou ld 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 or 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 a l i 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 obj ecti + of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or ban dform 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, online investigation is needed to define and locate the soils and miscellaneous a►reas.. An identifying symbol precedes the map unit nacre 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 soli 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 gilt 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 r 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 50 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 then Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have lithe or no soil material and support little or no vegetation. Rock outcrop is an example.

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 oil survey report and show the typical vegetation types for different soils found within and adjacent to the mine.

The nonacropland areas, have no special or unique characteristics, and. consist mostly of a weedy -grass covering. Cultivated Lands The backfilled f i l led 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 i it in is complete, and the areas are. released from the DRMS permit, the landowners will determine what will be planted on these areas. Vegetation hiprmation The following vege t at i on types were observed and mapped on the site. L.G.. Eve Ast, Inc.

Most of the acreage east of the Platteville Ditch, north of R ._ 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 0 to 85 percent grasses and 5 to 15 ercent cactus and weeds. Grass species makeup 85% to 90%, by weight, of the noncropland,vegetation found on the site. Irrigated cropland a covers about 0 % (about 533 acres) . Historically, these areas have been used as irrigated fields in which corn, winterwheat, sorghum, or other cash crops have been grown.

Ragsdale Reservoirs 90 Revised February it 2025 EXHIBIT I1,J SAILS & VEGETATION SOILS T E NTON 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, D - MINING P , 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 Rivers The first two () 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 minin.q w 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 612 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 L.G. EverEst1 line. Ragsdale Reservoirs Revised February it 2025 EXHIBIT L RECLAMATION COSTS The following information is provided to evaluate the amount iM1-cif bond needed at this time where L.G. Everist, s Inc. has Phases 1, 1A, 2 and 3 disturbed in some form or another. The numbers presented for each Phase are based on what is disturbed at this time. It is not necessary to import fill material to complete reclamation in Phase 1A, as discussed in the Mining Plan. The RECLAMATIONRECLAMATIONAcTIVITIES table below shows the various items needed to ✓ eclaim the west part of the mine with the 4 phases in full production in that area. In this scenario: : The first 4 tables are used in the Bond Cost Estimate but e ach 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 ✓ ubble 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 cart /fill method (5.65 c / l f t ). No dewatering cost is included since the slurry wall liners in Phase 1 and Phase 2 are installed and being tested or they effectively seal the mined area, and no dewatering is needed. In Phase 1A, the slope was mined 3h to iv. so no underwater sloping is needed and this Phase is approximately 30% backf filed, and not being dewatered, 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 where i n ing is nearly complete the side slopes are graded 3:1, the gravel areas between the slurry urry wall and the highwater hwater line have been left as -rave l and the armoring is completed on the west side. T . e cost to ✓ eclaim would include all items shown in the Table for that Phase, less the total armoring and slurry wall construction. Phase 2 - is being actively mined the first 50 acres has been stripped d and partially mined. The final slopes on the east Side are mined 3h to iv with less than 2600 feet of working face around the other 3 sides. The cost to reclaim Phase would include a l l items shown in the Table for that Phase, less the total armoring and the slurry wail construction that is included in the floating. bond calculations table. As mining progresses, the items in the Floating Costs table L. . Everest, Inc. R ag sd!a Fe Reservoirs Revised February 11, 2025 92 RECLAMATION COSTS (cONT) EXHIBIT L come into play. We will bond for a maximum of 100 acres stripped in front of the working. face that will be 2 600 ft long or less (5.65 d / l ft) cut /fill sloping) All other reservoir slopes will be finished and if needed, armoring installed as mining progresses to limit the amount of final sloping needed. Recoiling and seeding would be required on 100 acres stripped. The completed slurry walls total 16,100 ,eet long at 38 f t . deep average o more than a. 1000 foot section of bank armoring on the west bank of Phase 2 will require placement at any time requiring ... 5 cy/ if of material <2350 cyds). 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 liners in Phases 1 & 2 use the as -built lengths of the slurry walls in the affected Phases, times the average depth, which includes the bedrock key. The estimated unit cost for slurry rr wall, construction is based on $6.25/sq-ft with a 20% contingency for remedial work to cover any ✓ epair costs until the slurry. wall is certified at which time that slurry wall cost could be released. o QA/QC nutber is included since the walls are placed prior to mining beginning in any Phase. flame le is being used as a settling/fresh water pond. Bonding covers the cost of backfilling i l l ing if it is needed. Material t o 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 11..7 acres needed to be filled to a level t hat is 2 feet above the existing ground water elevation. No side sloping will be required, so 330,750 yards of backfill material is n eeded to finish backfilling. i l l in . The area will become cropland, so the bond estimate includes a cost for tempory seeding until a crop can be planted. Phase 3 is used as a processing plant, stockpiling. areas, potential drying pad for settling pond fines, overburden urden torage, topsoil storage and equipment parking areas. Approximately 60 ... acres has been disturbed on this stage, and would need to he ✓ esoiled l ed (81,500 yards) and graded* The concrete foundations to be removed for processing plant and conveyer piers 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.

Ragsdale Resentroirs 115 Revised February 11, 2025 L. a Ever s t, Ragsdale Reservoirs M-2002-007 BANK R-OING PLAN Februarytt 2025 This bank protection plan is presented to explain the bank armoring proposed for reservoir bank protection in Phase 1 and Phase 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 r€.vi s ed 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 ear flood event occur after an area has been reclaimed* On the armored areas a dirty sand and gravel (unprocessed) will be spread over the armoring to fill most of the large voids. The toe of the slope armoring will be at least 5 feet below the thal eg 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 retar removed, so that it meets the definition of Inert Materials. The concrete will be sized to 1.5 inches averaging 12 inches Fines will be mixed in. to fill voids* This size material will have a Safety Factor of 1 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 t 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 ank ... At no time will there be more than 1,000 feet of armoring needing to be placed. The tockpil of armoring material will be placed parallel to the water flow so it will not interfere with flows in the flood l a i n if flooding occurs. It will be within the setback between the permit boundary and the mine h l gh all so it is close to the area where it will be placed... 116 Ellicott Sand a Gravel LLC Page Bank Armoring Plan (February 'It 20'25) Reservoir Bank or ncra 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 he 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 thaiweg, have a 3h to lv slope and will be 2 feet or more thick. This is approximately 2*35 cydilft along the excavation bank slopes. Once sloping begins, th.e 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 su, rti documents Figure 1 a Bank Protection Plan cross section (revised) Safety factor calculation page 117 BANK A 10" MO ING PLAN ?Eriztal Sift. a channel! thaiweg _ A t 4 a at a 4 TOP OF SLOPE 4 30 ft . a 2.35 cyd/tct _1t 4 a . 4 lo 4 A e u i -50 -45 -30 -20 -10 0 10 20 TYPICAL CRbK BER?'I ARMCRFNG NO SCALE NOTES: 1..

Everist, Inc, (permittee a and operator) filed an application with the Colorado Division of Reclamation, Mining and Safety (DRMS) to obtain a permit to mine and reclaim a site known as Ragsdale Reservoirs (DRMS Permit M-2020-007). e have received the state and county permits and have recently been prepping the site prior to starling the mining operation. The site will be mined for the natural sand and gravel reserves and will be reclaimed as developed water storage. The site is located within portions of Sections 7, 8 17, 18, and' 19, all'within Township 2 North, Range 66 West of the Sixth Prime Meridian, Weld County, Colorado, The property is generally bounded by Weld County Road 22.5 on the north, adjacent farms on the east, Weld County Road 20 on the south, and the South Platte River on the west The s i to has an east side and a west side = with US Highway 85 and the UPRR R cutting through the middle. A copy of the vicinity maps. attached for reference. As an Owner of Record of a shallow well(s) within 200 feet of the permitted mining area, you are receiving his Well Testing Request letter. Please note that L.G. :verist expects this mining operation will have no or minimal l impacts on She prevailing hydrologic balance. Any sand and gravel mining -related impacts to groundwater wens near the pit will be mitigated through multiple measures, some of which include the installation of slurry walls around the perimeter of new reservoir mining phases prior to the start of dewatering in each reservoir phase. However, L,G, Everist has committed to the testing of shallow well(s) within 200 feetof the mine prior to installing slurry walls, dewatering, n , or exposing groundwater within 200 feet of ssaid well. L. n.

Finished grades and subgrade for riprap shall be determined from the height of each boulder used. C. Riprap: 1. The riprap shall be carefully picked and arranged so that adjacent rock surfaces match within two inches in top elevation and two inches along the vertical exposed face or channel side of rock. 2. Riprap shall be placed such that adjacent boulders "touch" each other and voids do not exceed four (4) inches. It is the intent of construction to minimize voids and grout placed between boulders. 3. CONTRACTOR shall, if deemed necessary, support the riprap from falling over before and during the placement of grout, backfill, and completing compaction Work on either side of the boulder. 4. Smaller rocks shall be "chinked in" to fill all voids behind the boulders. Smaller rocks shall also be used to "chink in" gaps larger than four inches. Placement shall be approved by ENGINEER prior to grouting. Ragsdale Underdrain 31 37 00 - 5 RIPRAP D. Grouting: 1. Prior to placing the grout, any type of debris, fines, smaller rock, or silt shall be removed from around or under and on the boulders. 2. Dewatering shall be implemented to guarantee that the grout will not be placed in water and for a period of twenty-four hours after the grout has been placed. 3. Keep riprap receiving grout wet at all times prior to receiving grout. 4. The concrete grout shall be placed by injection methods by pumping under low pressure, through a two- (2") inch maximum diameter hose to ensure complete penetration of the grout into the void area as detailed on the Drawings. The grout mix shall be stiffened, and other measures taken to retain the grout between the boulders. 5. Grout placement shall begin at the bottom of the lowest boulder and proceed upward to ensure no air voids exist between the grout, subbase, and boulders. 6. Grouted Boulder Height a. Grout shall be placed up to a height of one-half of the diameter of the top row of boulders or as directed by ENGINEER and shall be placed in the voids and behind the boulders and not on the surface of the rocks. 7. Grouted Riprap Height a. Grout shall be placed up to a height that is 4 -inches below the top row of riprap or as directed by the ENGINEER and shall be placed in the voids and behind the riprap and not on the surface of the riprap. 8. A "pencil" vibrator shall be used to make sure all voids are filled between the boulders from the subgrade and around the boulders to a depth as shown on the Drawings. CONTRACTOR shall have at least one standby "pencil" concrete vibrator ready for use for every two concrete vibrators in use during a concrete placement. The "pencil" vibrator may be used to smooth the appearance of the surface, but CONTRACTOR shall use a wood float to smooth and grade the grout around the boulders. 9. Grout should be troweled out and finished to minimize visibility. 10. Clean and wash any spillage before the grout sets so the visual surfaces of boulders will be free of grout to provide a clean, natural appearance, or if washing does not clean off grout residue, CONTRACTOR shall wash off any grout residue with muriatic acid and water, using a brush to scrub off the residue. 11. Grout shall receive cold or hot weather protection in accordance with the following: a. Placement of concrete or grout shall conform to ACI 306R-16. b. Earth foundations shall be free from frost or ice when concrete or grout is placed upon or against them c.
