Lupton Sand and Gravel November, 2024 MINING PLAN AND TIMETABLE exhibit D Exhibit ❑ MINING PLAN Existing Conditions. The methods described and approved in the original mining and reclamation plans for the Fort Lupton Sand and Gravel Mine (FLS&G) 1999 permit, and the 2012 amendment applications will remain unchanged unless discussed in this text. The Mining Plan described in the 2004 amendment will continue be used with the only change being the direction of mining. The other change is that mining will continue to the north into the newly added areas before moving to the southern end of the permit area. The future intent is to eventually remove the southern area from this permit into a new application that is being prepared. Map Exhibits C -Current Conditions, C -1 -Mining Plan, 0 -2 -Struc- tures and F -Reclamation Plan have been provided in this packet. In the 2012 amendment, LGE combined the Fort Lupton Sand and Gravel Mine (M-1999-120) with the Lupton Meadows Reservoir (M- 2002-104) and added 7 parcels north, south and west of the exist- ing mines. From that time until 2023 the mining Phases in the middle ❑f the permit area have been mined and reclaimed. The area that has been released has created a 2 -part mine as shown on the maps. The two (2) new areas to the permit boundary will increase the permit area by approximately 202.26 acres ±. EXHIBITC -CURRENT CONDITIONS MAP shows the area being added to the permit and will reflect any changes to the mining and Reclamation Plan in the existing area. There is very little change to the south area reclamation plan for the existing area except some of the oil and gas facilities have been removed which will allow for an expan- sion of some of the future reservoirs shapes. Nineteen of the twenty mined areas shown on the maps will be slurry wall lined and developed as a series of water storage reservoirs ranging from 10.26 t❑ 70.00 acres ±. The exceptions are the Deep Lake Phase that will be reclaimed as a pond and the southern end of the Sandstead Phase that will be backfilled with fines 2 feet above ground water and revegetated. The north end of the Sandstead Phase may become a lined reservoir. TABLE D-1 -MINING TIMETABLE on Page 9 is a list of the mining phases that will be referred to in the following text. This timetable has been updated to reflect changes to existing Phases. EXHIBIT B -VICINITY MAP shows the parcels that will be added while the Mining and Recla- mation Plan Maps show how the site will be developed. The total number of phases added to the Fort Lupton Sand & Gravel Mine is four and the new area will add approximately 7-15 years to the life to the mine. It is estimated by adding the new area, along with remaining reserves, that the life of the mine will be from 15 to 25 more years. This life span is subject to fluctuation depending on market conditions. The current bond for Ft. Lupton S&G is $2,002,400.00. The bonds include surety for 20,134 feet of slurry wall and construc- tion of 16,650 feet of bank sloping. At this time the applicant has a contract with the City of Aurora to develop 5 water storage reservoirs on the northern parcels of the property. This in- cludes 256.59 acres of the existing permit area, south of Weld L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel November, 2024 3 MINING PLAN EXHIBIT ❑ (CONT) County Road 18. The Sandstead Phase, the new north areas as well as the southern area, will be marketed by L.G. Everist, Inc. as they ar developed. The areas being added have been used primarily as agricul- tural land. The Northwest Phase is broken into 3 use areas, farm yard with a house, wetland/creek area and agricultural produc- tion. The house will be removed prior to mining. Mining will take place on the yard and agricultural area in this Phase. The Northeast Phases are mostly grass land with 2 irrigation ditches crossing the site and a small farm yard near the northwest cor- ner. LGE will maintain 50 foot setbacks along the diagonal ditch corridor that has the Meadow Island #1 and the east lateral of the Lupton Bottoms Ditch. If practical, the north/south leg of the Lupton Bottoms ditch will be moved to the east side of North- east Phase #3 so it can be combined with Northeast Phase #2 as show in Option B. The applicant will bond the amended property in phases, and wishes to retain the option to seal each reservoir with either a slurry wall or a compacted liner, until just prior to bonding that particular phase. At the current time, slurry walls have been constructed around the active mining areas and the reservoir slopes are built by backfilling and grading or are in the process of being completed. TABLED -1 -MINING TIMETABLE has a current list of all certified liners or lined areas being tested. At any given time, mining and reclamation may be occurring in one or more bonded phases to accommodate blending of materials and relocation of the processing plant and settling ponds. There will be times when reclamation is being completed in one phase while mining begins in another phase. Mining will progress from the existing permit area into the Northeast Phases then move to the Northwest Phase leaving the Ft Lupton West Phase as the last area to be mined. The arrows on the EXHIBIT C-1 -MINING PLAN MAP show how mining will progress through the mine area at this time. The order of mining in the south area will start on the west side and mine to the east jumping from Phase to Phase. The last area to be mined will be the future Plant Site area, see Exhibit O-1 Mining Plan Map. Optional Mining and Reclamation Plans. Due to the constantly expanding and changing development nature of the oil and gas and other utility operations in this area, L.G. Everist is submitting these Optional Mining and Recla- mation Plans with this amendment to guarantee the flexibility to make changes to mining areas and reservoir shapes throughout the life of the mine. During the current run of mining and reclama- tion we have seen many changes to the Oil and Gas(O&G) facilities that are reflected on the current version of the maps and mining areas. We continue to stay abreast of, and in contact with, the oil and gas and utility companies about future structure and easement changes, including plans to relocate some of their facilities, plans to remove some of the older wells and facili- ties, and plans for oil and gas companies to add new structures as their permitting allows. L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel November, 2024 4 MINING PLAN EXHIBIT ❑ (CONT) For example, between 2012 and 2024 many of the wells and facilities on the south area have been removed and the reservoir areas adjusted to show those changes. Many additional changes are expected in the future similar to this example. As mining progresses through the mine and into a new area it may be to our advantage - or we may be required by law to allow oil and gas companies or ditch companies to exercise their rights - to revise the shapes of the reservoirs due to changes to their facilities, gaslines, wells or drilling pads or ditches. These changes may affect reservoir shapes, combine or split reservoirs, add or subtract oil and gas operations areas, gas lines, ease- ments, etc. Therefore, we are presenting these optional plans to cover the possibilities with the understanding that the mining and reclamation methods will remain unchanged, but the configurations and areas of the mined and reclaimed areas may change. Optional Mining Plan. Option A - The mining areas shown on the large map on EXHIBIT C-1 MINING PLAN MAP is Option A. This option shows the most conser- vative (and current) mining plan and it assumes no further changes to the location of ditches, oil and gas wells, gas lines or facilities before mining ends. Option B - The smaller map inset in the upper corner is Option B and is a more optimistic plan showing removal or reloca- tion of numerous wells, gaslines and facilities to allow removal of more gravel and increase the amount of water storage on the site. For Option B, the South Area remains as originally planned in 2012 but the new north area may have the ditch moved between Northeast Phases #2 and #3 to create one large reservoir. Mining Methods overview The working face will be mined near vertical to maximize removal of material from the mine. At the widest point, the longest working face will be approximately 1,700 feet long. If mining ended prematurely, this slope will be reclaimed using a cut/fill sloping method instead of backfilling. As mining reaches a setback limit, backfilling will commence within 3 to 6 months maximum so as to leave a 3:1 slope along the mine exterior, oil and gas facilities and the ditches. No more than 2,000 linear feet of side slope highwall area will need backfilling at any -one- time. This can be done because we plan to start backfill sloping whenever a new area is stripped so the material only has to be handled once. The mining setbacks will vary from 15 to 275 feet from the permit boundaries, structures and river as allowed by each use agreement of geotechnical analysis for said structures. No mining will be done in the setback areas but they may be disturbed as mining and reclamation progresses thru a phase. For example, around oil/gas wells we will maintain an eighty (80) foot radius around each well head when mining, but leave a 150 foot radius when reclamation is complete. EXHIBIT C-1 -MINING PLAN MAP shows how this will look. L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel November, 2024 5 MINING PLAN EXHIBIT ❑ (CONT) Around the rest of the mine, the setback line will be to the outer edge of the slurry wall or the top of the excavation limits. The temporary topsoil stockpiles placed within the setbacks will also limit noise and visual impacts to off site areas. In some cases, the setbacks will be used as a place for roads to access the mine exterior, ditches and access for the oil and gas facili- ties. The setback areas will be reclaimed if disturbed. The following information is a recap of the methods currently used at the mine and will continue to be used as mining progresses through the areas added by this amendment. This mine will be operated as a dry -mine. Slurry walls will be constructed to the Division of Water Resources specifications around the perimeter of each additional mine area prior to commencement of mining in the new phases. This isolates each mining area from the surrounding groundwater table and allows for dry -mining of each mine area. However, if a slurry wall is not feasible, the Applicant will utilize a compacted liner to seal the reservoir areas for the end use as water storage. Design of the liner will follow the Divi- sion of Water Resources Guidelines also. Slurry wall design documents were submitted and deemed adequate to the Division in 1999. Slurry walls installed using this design have been con- structed successfully on the 5 lined areas currently complete(and the 6 already released from the permit). Additional monitoring wells have been installed along the western, eastern, and northern sides of the new areas in the amendment area. Ground water monitoring, and ground water quality testing plans are included in ExH[BITG-WATER for the amendment areas. Prior to mining moving into those areas just north of WCR 14.5, the Plant Site will be moved to the Parker #4 Phase in the southern area, adjacent to the access road that now serves the agricultural areas. Mining operations within each new phase area will include topsoil and overburden stripping, and excavation of dewatering trenches, and settling ponds. Raw materials will be excavated with excavators, front-end loaders, scrapers and/or bulldozers. As areas are cleared and stripped, previously mined slopes will receive backfill material to establish the permanent design side slopes. A conveyor is used to transport the raw material from the areas north of WCR 18 to the Plant Site in the existing mine. Explosives will not be used at this operation. The reservoir access roads will be placed in the 25 foot wide setback between the slurry wall and the top of the slope into the reservoir. The disturbed areas from the setback line to the water line or top of bank armoring, will be left as a gravel surface instead of being resoiled and seeded. Adequate amounts of the stripped topsoil and overburden will be stockpiled for later use in reclamation in the areas that will be seeded. Topsoil and overburden stripped from subsequent mine areas may be placed directly on the seed bed in previous mine areas so it only has to be handled once and the disturbed areas will be concurrently reclaimed. The exact location of topsoil and overburden piles are L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel November, 2024 6 MINING PLAN EXHIBIT D (CONT) unknown at this time, so we have shown the approximate location on EXHIBIT C-1 - MINE PLAN MAPS . Mining within each phase will begin once topsoil and overbur- den has been removed from that phase area. Excavated materials (pit run) will be removed via front-end loaders, or excavators and may be loaded onto a field conveyor and transported back to the processing plant, or loaded into off -road haul trucks for trans- port to the plant site. Mined slopes will range from near verti- cal to 0.5:1, or as required by the Slope Stability Analysis and Setback Agreements (see EXHIBITS -STRUCTURES from the 2004 submittal (included in this packet). As soon as mining limits have been reached in one phase area, reclamation of the pit edges within that phase area will begin. This will allow for concurrent backfilling of the pit perimeter with previously stripped overburden and/or material stripped from the next phase area to be mined. Access roads built during slurry wall construction and mining will be left as access roads around the reservoirs or for access to oil and gas wells on the site. Slurry walls have been installed around Swingle North, Swingle South, Ft. Lupton West, Parker-Panowicz and the Blue Ribbon Phases. Testing is complete and certified for all but Blue Ribbon and Swingle South. A slurry wall is planned for the small lake on the north end of Sandstead. We anticipate slurry wall construction will begin soon after permit approval on the North- east Phases. River setback and Bank armoring The only place the South Platte River is within 400 feet of the mining area is along the east sides of Northeast Phases #1 & #3 in the amendment area. Along this stretch the slurry wall will be installed at least 200 feet from the edge of the river. The mining setback will be 275 feet where the finished top of the slope and armoring will start. Na more than 1,700 feet of 1:1 cut/fill sloping and 2,000 feet of 1:1 backfill sloping in any one phase will be needed and no more then 2000 feet will need armoring. Armoring will be done, using the technique, and materials described in the BANK ARMORING PLAN in the APPENDIX of this application packet. Water Diversions and Impoundments The entire site will be graded in phases to direct storm - water runoff towards interior ditches and dewatering systems. A CDPS permit for the existing mine operations is in place from the Colorado Department of Public Health and Environment (CDPHE) for the current dewatering operations. This permit will be modified, if necessary, to accommodate the additional parcels. As the slurry walls are installed, they will be constructed around the perimeter of each new phase prior to commencement of mining. This will seal off each individual phase area, and preventing infiltration of groundwater into the mining area. Once the initial groundwater quantities within each mine area are pumped out, continued dewatering will not be required except on an as -needed basis after significant weather events. L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel November, 2024 7 MINING PLAN EXHIBIT D (CONT) Description of Overburden, Deposit and Underlying Stratum Across the entire amendment area, approximately 3 feet of overburden (including approximately 6 to 18 inches of topsoil) will be removed from the mine areas and stockpiled for plant - growth material in surface reclamation or used as backfill for the pit slopes. An average thickness of approximately 33 feet of sand and gravel exists across the amendment area. Mining Timetable The continuing uncertainty of economic conditions in the construction materials industry precludes an accurate forecast of demand for materials during the life of the mine. This pit will be operated year -around by L.G. Everist, Inc., weather permitting. There may be periods up to 18 months or more when the demands for material is slow and no mining will take place, creating an "intermittent operation" situation. We therefore, can only estimate the mining timetable based on an average year and may expect a specific year to vary widely from the average.

This will remain a dry mining operation. All of the map exhibits have been presented on 2 sheets labeled North area and South area for easier review. When referring to a map ex- hibit it is inferred that both should be reviewed. EXHIBITSC-CURRENT CONDITIONS MAP show the current permit area and the area being added to the permit. The current post mining land uses are listed as developed water storage surrounded by access roads, gravel surface areas and revegetated areas. The following information makes change to the reclamation around the reservoirs. The plan is to reduce the resoiling and revegetating. Instead of revegetating to the water line, a gravel surface will be created from the mine setbacks to the highwater line, except on bank armoring areas where no cover will be placed on the armoring. This solves a problem created by not having sufficient levels ❑f moisture in the ground due to the water level fluctuations as the reservoirs fill and empty. A gravel access road will be placed around the reservoir. Three areas will need revegetation, The scale house triangle in Parker- Panowicz, the area south of and around the Sandstead Reservoir and Deep Lake. All other disturbed areas will have a gravel surface. More detail is provided in the following Reclamation Plan text and a typical cross section showing this is provided on the EXHIBIT F - RECLAMATION MAP . As with the currently permitted mine area, the new proper- ties will be reclaimed as lined water storage reservoirs. Each of the additional properties will either be sealed with a slurry wall or clay liner. The applicant proposes to bond each phase prior to mining and to determine the type of lining prior to posting a bond for that phase. Please refer to TABLE E-1 RECLAMATION TIMETABLE for information on each Phase of Reclamation. Reclamation Plan Currently, the undisturbed and amendment areas of the mine site are primarily irrigated agricultural land. The area is broken into 6 different use areas. Please refer to the VEGETATION MAP in EXHIBIT UJ -SOILS AND VEGETATION for the location of each area described. The current uses are, mining operations area; non - irrigated pasture; irrigated crop areas; ditch & river corridors & wetland area, oil/gas operations areas and high capacity gas pipeline ROW's. The agricultural uses will continue as mining progresses until an area is taken ❑ut of agricultural production and prepped for mining. There is no native vegetation present on the agricultural areas because of the intensive agricultural practices that have taken place ❑n the land. In most cases the oil/gas operations areas have little vegetation and the high pressure gasline ROW's have been farmed for many years and vege- tation cover on those areas is consistent with farmed areas. The narrow band along Little Dry Creek/Slate Ditch and the Meadow L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel November, 2024 9 RECLAMATION PLAN EXHIBIT E (CONT) Island Lupton Bottoms ditches have been constantly disturbed by ditch maintenance leaving only the river corridor, that will not be disturbed, with vegetation that may be considered native. The typical vegetation descriptions that have been submitted in EXHIBITS I & J - SOIL5 AND VEGETATION in previous permitting packets will match these agricultural uses as the crops rotate throughout the years. The EXHIBIT F -RECLAMATION PLAN MAP shows a cross section sketch of the proposed sloping plan and reclamation activities that will surround reservoirs in this plan. Under the contract with City of Aurora for the water storage reservoirs, the applicant has to turn over to Aurora, for contin- ued development, any reservoirs that have been significantly reclaimed. It has been agreed that this condition will exist once a reservoir liner has been certified by the Division of Water Resources, sloped, the surround gravel surface is complete. The change to graveling the band between the setbacks and the highwater line (or armored areas) eliminates the concerns that during Aurora's development, any revegetated areas would be disturbed, destroying any grass planted. In the new area where mining will take place within 400 feet of the river, the bank will be 275 feet from the river bank at which point the slope into the reservoir will be backfilled and sloped. In this area, approximately 2,000 feet will need 1:1 backfilling, and will not be left open for more than 12 months. Armoring will begin as soon as bank sloping is complete on each 1,000 -ft section. This will als❑ ensure, that if mining ceases before the resource is exhausted, ❑nly a minor amount of work would have to be done to finish reclamation on the disturbed area Armoring in the Northeast Phases #1 and #3 will progress with sloping, so approximately 2,000 feet will need to be com- pleted at any time. N❑ armoring will be done in the existing permit area. The BANK ARMORING PLAN is in the APPENDIX and explains how and where the armoring will be placed. LGE will be working with the Town of Ft. Lupton for direc- tions on Flood Plain development. This facility is not in an Urban Area, not near public land, ❑r facilities where public safety is a concern so, inlet/outlet structures for private reservoirs are not needed. There are no plans to install Inlets or Outlets for the reservoirs. Those will be the responsibility of the reservoir developers. The following approved seed mix will be used to seed areas where reclamation calls for revegetation. This mix will place approximately 41.2 seeds per pound per sq-ft as prescribed by the NRCS planting guidelines. APPROVED SEED MIX Species Western Wheatgrass (Aribba) Big Bluestem (Champ) Blue Grama (Hachita) Switchgrass (Blackwell) TOTALS Lbs. PLS/Acre 5.00 2.50 0.50 1.75 9.85 L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel November, 2024 10 RECLAMATION PLAN EXHIBIT E (CONT) The reclamation timetable shows the types and amount of land use in each Phase when reclamation is complete. Approximately 12.2% 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 or areas to❑ small to mine that will be kept in their natural state. As mining progresses, the perimeter slopes will be back - filled and graded at or near 3h to lv as discussed in the MINING PLAN. This will insure that when mining ceases only a minor amount of work will have to be done to finish reclamation in the disturbed area. The placement of the temporary soil stockpiles around the setback/perimeter of the mined area would be thereif needed. Since the area between the liner, the water line and/or top of the armoring will be a graveled surface area, no resoiling will be needed. The graveled surface will mean the above -water- line areas simply have to be shaped and graded. We expect to salvage sufficient topsoil to meet reclamation requirements. Of the 809.0 acres ± in the permit area, only 42.1 acres ± or approximately 5.7% will need resoiling and revegetated and remaining above water gravel surface will cover 146.5 acres or 18.1% of the area to be reclaimed. The remaining area will be reservoir area, covered with water or undisturbed area. Observations at the site show that topsoil on the property has a salvageable depth ❑f 6 t❑ 12 inches, averaging 8 inches except in isolated locations. There appears to be more than adequate soils to meet the demand for this site. Setback areas will not be stripped, and the disturbed areas inside the setbacks will not be resoiled. Gravel surface maintenance roads will be built around each reservoir and left around each gas/oil well where no seeding or resoiling will take place. This will provide room around each well ❑r reservoir t❑ service it as needed by the well or reservoir owners. Some inert fill (as defined in Colorado Department Public Health and Environment regulations) may be imported for recycling and resale or in rare cases for reclamation purposes. On -site generated inert material will be used for bank sloping, buried in bank areas around the lakes or will be recycled/sold. An inert fill Notice and Affidavit are included in the Appendix for this mine. Existing soils in place have been capable of producing a fairly dense cover of irrigated crops and dryland grasses and should be suitable for use when revegetating the areas where seeding will be done. These areas will be returned to at least their present vegetative condition when reclamation is complete. Under normal conditions, the ❑perator will strive for a 30 to 40 percent cover rate on the revegetated areas when reclamation is complete. Under normal weather conditions, an adequate moisture re- serve will be present for establishment of the proposed seed mixture. No irrigation will be used during reclamation since the plan is to establish a vegetation cover that is not dependent on irrigation to survive. L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel November, 2024 11 RECLAMATION PLAN EXHIBIT E (CONT) Optional Reclamation Plan. We are submitting two options for final configuration of the reservoir areas as well. Option A - The reservoir configurations for Option A are show on the large EXHIBIT F - RECLAMATION PLAN MAP . Option B - The inset map shows the reservoir configura- tions under Option B. The methods used t❑ reclaim the reservoirs will be the same for both options. The difference may be an increase/decrease in the volume of developed water storage and an increase/decrease in the amount of graveling and revegetation necessary. We do not know when the Mining Option B or the Reclamation Option B or some part(s) of either ❑r both will be implemented, but we are including these optional plans to increase the flexi- bility of this permit and account for the inevitable changes when mining the site. 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. Deep Lake Option Mining has ended in Deep Lake and it will not be lined. The area around the existing lake will be graded, shaped and revegetated. The town of Ft. Lupton will receive this property once it is reclaimed and will assume responsibility for a water augmentation plan. RECLAMATION PERFORMANCE STANDARDS The property will be mined in compliance with the Reclama- tion Performance Standards of Rule 6. Grading will be performed to create a final topography that is compatible with the intended final land use. The slopes will vary depending on the final use proposed in a particular area, reservoirs or grassed areas; the remainder of the area will retain its present drainage pattern. The RECLAMATION PLAN MAP shows how the area will be reclaimed. The pit will be reclaimed s❑ that a suitable grade for drainage exists, all surface runoff will be directed into the reservoirs created by mining. Settling ponds may be silted in from wash water, this type of backfilling tends to firm up and stabilize during the first 18 months after being placed. All grading will be done in a manner to control erosion and to protect areas outside the affected land from slides or other damage. Backfilling and grading will be completed as soon as feasible after mining is completed in a given area. There are no drill or auger holes on the land. Maximum slopes will be within L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel November, 2024 12 RECLAMATION PLAN EXHIBIT E (CONT) the limits set forth in the Rules and Regulations of the Board and will be capable of being traversed by machinery. All refuse will be hauled away or disposed of in a manner that will control unsightliness and protect the drainage system from pollution. There are n❑ acid-forming or toxic materials involved in this operation. The minimal amounts of petroleum products stored at the site will be stored as prescribed by applicable laws. The storage tanks will be surrounded by a berm or secondary containment such as storing the tank in a larger metal container adequate to retain any fluid should a tank rup- ture. In addition, there is adequate absorbent materials on site to contain any spills that would occur. The operator does not expect prevailing hydrologic condi- tions to be disturbed. L.G. Everist, Inc. will comply with applicable Colorado water laws and regulations (as the operator understands them) governing injury to existing water rights in order to minimize any disturbance, which might occur to the prevailing hydrologic balance of the affected land and surround- ing areas and to the quality ❑f water in surface and ground -water systems both during and after the mining operation and during reclamation. In addition, the operator expects to comply with applicable Federal and Colorado water quality laws and regula- tions. Any water used in the ❑peration of the processing plants and gravel pit will come from water ❑wned by L.G. Everist, Inc. or purchased from an outside agency suitable for that use. ExHIBITG -WATER contains specific information concerning impacts and uses of water at this mining ❑peration. This is not a dredge facility, so there are no temporary siltation structures involved in this operation and no mining will be done within the confines of the river. If a U.S. Army Corps of Engineers Permit is required for mining in waters of the U.S., it will be obtained prior t❑ disturbing those areas. Settling ponds will be constructed on the site to collect and recycle water from the washing operation. There will be no earthen dams on the mined area. The mining and reclamation plans consider existing wildlife use of the site and final reclamation will enhance the area for continued wildlife use. However, creation and management of wildlife habitat is not a specific part of the reclamation plan. Topsoil in the area is good quality and deep enough to salvage what is needed for reclamation. When topsoil is removed to reach the mineral deposit, it will be segregated and stock- piled. If the topsoil piles remain undisturbed for more than 180 days, the approved seed mix will be planted on the piles or other means will be employed t❑ preserve the topsoil from wind and water erosion. This will keep it free of contaminants so that it remains useful for sustaining vegetation when reclamation begins. The stockpiles will be located in areas where disturbances by ongoing mining operations will be at a minimum, i.e. along set- backs on the pit perimeter. The topsoil will be handled as little as possible until it is replaced onto areas where needed for reclamation. We will take measures necessary to insure the stability of the replaced topsoil ❑n graded slopes and ensuring L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel November, 2024 13 RECLAMATION PLAN EXHIBIT E (CONT) that it is spread as evenly as possible. Fertilizer and other soil amendments will be used, ❑nly if needed, in accordance with NRCS recommendations. Reclamation will begin once enough area has been opened so that any reclamation completed will not be disturbed as mining progresses. This may take one ❑r more years depending on eco- nomic conditions and the amount of material mined. By the time mining is completed 75 to 90% of the total mined land will be reclaimed. As mining ends in each reservoir area, only backfill- ing, grading and shaping of the final mined slopes, bank armoring if needed, graveling the surface as needed. Where needed, the proposed seed mix will be planted during the next planting season after resoiling is completed. The area will be monitored for success of revegetation until accepted by the Division for re- lease. If revegetation failures occur prior to release, an analysis of the site will be made and the area will be revegetated again as necessary. Reclamation Timetable The numbers presented below represent our estimate of the various area of disturbance in the mine area. They may change as the actual mining progresses through the site.

Lupton Sand and Gravel November, 2024 15 BASELINE DATA water, wLLdtL e, soLts, vegetation, e2 -mate EXHIBIT G WATER INFORMATION Introduction The amended Fort Lupton Sand and Gravel Mine is located in parts of Sections 19, 30 and 31; Township 2 North, Range 66 West, and Sections 24, 25 and 36, Township 2 North, Range 67 West of the 6th P.M., Weld County, Colorado. The site is approximately one mile northwest of the City of Fort Lupton, Colorado. MAP EXHIBIT B-'1 shows the layout of the permit area and amendment portions in relation to surrounding areas. For the existing permit area, ground water studies done during the 2004 amendment explained the impacts expected due to liners being placed in the South Platte alluvial valley. In general, the ditches, river and streams lying across the site, or on either side will limit mounding ❑r shadowing around the site. Impacts from other permitted mining operations that have installed liners south of WCR 18 and along WCR 25 between the new parcels will also contribute to the change in historic groundwater levels that LGE has no control of, nor can correct if needed. Mitigation Trigger Starting in 2004 L.G. Everist, Inc. began t❑ collect ground water elevations on areas around the mine. The period from May 2004 to August 2006 was used as the baseline for triggering mitigation actions. Since late 2006 ❑utside influences not caused by LGE continue to act ❑n the groundwater levels that have/are changing the levels and impacting our trigger point. There has been an increased gravel mining presence north of the Fort Lupton Sand and Gravel Mine that has dewatering operations west of monitoring wells 9 & 10. Impacts are also beginning to be seen to ground water levels in the Parker Phases on the south due to the new mining operation and liners installed south of WCR 14.5. Another outside influence is the reduction/elimination of groundwater wells pumping, mandated by DWR, from the South Platte River alluvial aquifer. Since 2012 the water table has stabilized from 2.5 to 3 feet higher than the DWR pre -pumping ban and the new normal levels are reflected in the data LGE has collected since then. During our investigations, we determined the causes were due to system -wide environmental factors out of our control. Realistically the mitigation trigger number should be based on a plus or minus 5 foot over the high and low range of the baseline. LGE has not had a problem with mounding being a problem where the slurry walls are in close proximity to a flowing water body as discussed in the January 2005 Wright Water Engineers report. For example, there is flowing water along the east side with the South Platte River & Lupton Bottoms Ditch east lateral; on the west side with the Lupton Bottoms Ditch and Little Dry Creek/Slate Ditch, and along the south side of the Blue Ribbon Parcel next to the PVIC irrigation return flow ditch. However, we have found that activities such as: damming ❑f the Little Dry Creek/Slate ditch by beavers, and local farmers flood irrigating and dumping their L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel November, 2024 16 Water Information (cont.) Exhibit G excess water in Little Dry Creek/Slate Ditch have caused an increase in ground water and flooding along that waterway. This is an example of how a trigger point is reached but not created by our activities. The remaining parcels that are not protected by a surface water body are agricultural lands with no structures within 200 feet. 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 River, associated with mining, are currently mitigated with a DWR approved SWSP to prevent injury to vested senior water rights. The reclamation plan for the amended area will create 4 slurry wall sealed pits that will not be hydrologicly connected t❑ the South Platte River alluvial aquifer. The south side of the Sandstead Phase is partially back filled and will be completely filled and reclaimed before being released. The other mining Phases actively being mined were sealed prior to mining, thereby eliminating ground water draw down typically associated with pit dewatering and the possibility of any adverse impacts to nearby alluvial wells. Potential Water Resource Impacts Ground Water Wells The amended Fort Lupton Sand and Gravel Mine will have minimal impacts on the prevailing hydrologic balance. Sand and gravel mining related impacts to ground water wells near the pit will be mitigated through the installation of slurry walls around the perimeter of new mining Phases prior to the start of dewatering these Phases (see EXHIBITD-MININGPLAN. PLAN . Potential ground water depletions associated with the settling pond will be minimal due to the fact that they will be backfilled with wash fines. FIGIJREG-1 is an updated list of wells from the office of the Division of Water Resources files, the wells (highlighted in blue) outside the permit area are not owned by L.G. Everist, Inc. Of the 40 wells within 200 feet ❑f the permit area, L.G. Everist, Inc. owns 32 wells. Of the 8 remaining wells, not owned by L.G. Everist, 2 are deep wells (highlighted dark blue) and 6 are shallow wells drawing water from the surface aquifer (highlighted light blue). The locations of the wells on the list are shown on EXHIBIT G-1 . L.G. Everist, Inc., has 27 groundwater monitor wells on or around the permit area they monitor monthly for ground water levels. EXHIBITG-2 shows the location of existing monitoring wells around the mine. Historic monitoring data is available for these wells. The applicant installed 4 additional ground water monitoring/water quality monitoring wells around the Northeast and Northwest Phases as part of the due diligence process when buying L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel November, 2024 17 Water Information (cont.) Exhibit G the property. Data collection began, in first quarter 2024 and will continue until 5 quarters worth has been obtained, as discussed in the Water Quality Monitoring and Sampling Method Plans supplied in this Exhibit. Post Reclamation Any slight ground water 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 ground water mounding will be mitigated by the South Platte River and the Lupton Bottom Ditch East Lateral on the east, the Lupton Bottom Ditch ❑n the west and Little Dry Creek/Slate Ditch in the southwest. These existing water features will serve to regulate and balance ground water elevations in the alluvium adjacent to the sealed pits. The amendment areas are located north of Weld County Road 18 and adjacent to a lined reservoir currently being reclaimed by another operator. Therefore, ground water mounding and shadowing on the east, south, & west sides associated with the slurry wall sealed portions of the Northeast Phases are not anticipated to produce any adverse impacts t❑ adjacent properties. Post -reclamation ground water depletions, if any, will be replaced through a Colorado Water Court approved Plan of Augmentation. Finally, L.G. Everist, Inc. has entered into a contract to sell its developed water storage at the Fort Lupton Sand and Gravel Mine to the City of Aurora. At this time all of the reservoirs in the existing north area are under contract with the City of Aurora with the exception ❑f the Sandstead and Blue Ribbon Phase. Under the sales agreement, as water storage reservoirs are completed, they will be sold to and transferred to the City of Aurora for use as municipal water storage. Since the 2012 amendment, the release and transfers have been completed for the Hill -Oakley and Fort Lupton East, Meadows Lake, Meadows West and Vincent West reservoirs to the City of Aurora. The remaining reservoir transfers will be complete once we receive final reclamation approval and release ❑f each from the Division. Discharge Permits Surface Water Management When necessary, ground water will be pumped and discharged from the Fort Lupton Sand and Gravel Mine under a CDPS Permit which the operator obtained 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 prior to modifications of the discharge points. Runoff from disturbed areas will be managed to protect against pollution of either surface or groundwater by directing runoff into the site. L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel November, 2024 18 Water Information (cont.) Exhibit G Consumptive Water Use The current annual consumptive uses of water associated with the Fort Lupton Sand and Gravel Mine and aggregate production are described below. USES (2025) VOLUME Acre-feet 4% Moisture Loss in Material 26.49 Dust Control 0.75 Water Surface Evaporation 85.21 Total Consumption (Augmented) 112.44 Substitute Water Supply Plan Ground water depletions associated with L.G. Everist's Fort Lupton Sand and Gravel Mining operation are currently covered under a substitute water supply plan (SWSP) pursuant to C.R.S. 37- 90-137, approved by the Division of Water Resources (DWR) for replacement of the ground water depletions due to mining. This plan is updated and renewed every 2 years. The Applicant will maintain a SWSP throughout the life of the mine. After completion and reclamation of all lined reservoirs there will be no long-term evaporative depletions. However, if any unlined open surface water areas remain at the end of reclamation, then a court -approved augmentation plan will be applied for before reclamation is complete. 100 -Year Floodplain Portions of the Fort Lupton Sand and Gravel Mine are located within the 100 -year floodplain of the South Platte River. The applicant has a Flood Hazard development Permit from Weld County for the original permit area. On 12/09/2008 Deere & Ault prepared a Flood Plain analysis (in Division's file) showing that there will not be an appreciable increase in flood elevation due to the mine. The information provided in this report is applicable to the new areas as it lies within the South Platte alluvium immediately adjacent to the permit area. The location of the 100 year flood line on the affected lands was transferred from the 2023 updated FIRM Panels 0812302102E and 08123C1915F to all maps. L.G. Everist, Inc. M-1999-120 Ft.

An amended mining permit for the Fort Lupton mine site incorporates the northern portions into the mining site. The amendment area is approximately 202.25 acres and is located northeast and northwest of the current Fort Lupton mine site. The purpose of this Groundwater Quality Monitoring Plan (GWMP) is to provide a description and assessment of the potential of the introduction of pollutants into the groundwater during mining activities, and to assess if and how water quality may change over time. The plan also provides information about the collection of water level measurements to show water level changes over time. Sample collection is described in a separate Groundwater Sampling Plan (GSP). The groundwater sampling procedures, sample handling, and laboratory methods are presented in the GSP. This GWMP will designate what data is collected and how it may be interpreted and modified as the mining activities progress. Both the GWMP and the Groundwater Sampling Plan (GSP) will be followed for all groundwater monitoring done at the LG Everist — Fort Lupton North (LGE-FLN) site. The Colorado Division of Reclamation, Mining and Safety (DRMS) requires a GWMP for the LG Everist — Fort Lupton (LGE-FL) mining permit to establish baseline constituent concentrations for comparison to future sample results to assess whether mining activities are impacting groundwater quality. Water quality monitoring wells (WQM), approved by DRMS, will be sampled for five quarters to establish a baseline set of data. Future samples may be collected from the water quality monitoring wells (WQM) and compared to the baseline data during mining activities. 2.0 MONITORING PLAN COMPONENTS The network of groundwater monitoring wells is shown in Figure 1 — Monitoring Wells. The entire well monitoring network includes the water quality monitoring wells and the other water gauging wells. All of the wells are completed in the uppermost aquifer and located in up -gradient and down -gradient positions in the alluvium. Additional monitoring wells may be included in the future as necessary, or in response to regulatory concerns. Baseline sample data is collected from the WQM wells. The baseline sample data from each of the WQM will be compared to future sample results. The comparison of the baseline data and additional WQM sample results is used to assess potential changes in water chemistry that may cause overall changes in water quality downstream. LL, l MOLEN LG Everist Fort Lupton GW Monitoring Plan Page 2 of 7 27 Groundwater Quality Monitoring Plan 2.1 Groundwater Flow Direction The groundwater flow direction generally follows the topographic gradient. Groundwater generally flows from south to north, in the general flow direction of the South Platte River alluvium. 2.2 Existing Groundwater Wells Existing groundwater wells have been used to measure water levels over the past several years. The groundwater well locations are presented in the L.G. Everist, Inc. Fort Lupton Sand and Gravel - Figure 1 Monitoring Wells, The majority of the monitoring wells are water gauging, used for water level measurements, and are also shown in Figure 1. Water quality groundwater monitoring wells are generally located at the perimeters of the site and in areas that will not be mined in the near future. The water quality monitoring wells (WQMs) are the only wells used to obtain baseline groundwater quality data for the LGE-FL site. Groundwater wells are completed with a 2 -inch diameter PVC casing and screen. The wells are constructed with screening across the entire water bearing zone, and solid piping to the surface completion. A washed sand pack is placed from the base of the well to one -foot above the screened interval. A lockable metal well cover surrounds the PVC well casing and is imbedded in a concrete pad installed at the ground surface.

The groundwater monitoring wells, MW -02n, MW -03n, and MW -04n are installed as downgradient water quality sampling points. The downgradient water monitoring well MW -1n is both a water quality well and a point of compliance (POC) well.

The water level measurements will continue to be made during the mining activities at the mine site and into the future as required by the mining permit. Water quality monitoring begins at the new portions of the mine site are added to the mining permit through the amendment process. The water quality monitoring is a DRMS requirement that will be completed. 3.1 Water Level Monitoring Water level measurements have been made throughout the mining operations. Water level measurements are made in monitoring wells at least once every three months (quarterly), and usually monthly. Water level measurements collected in concert with water quality sampling can serve as quarterly water level measurements for the purposes of this monitoring evaluation plan. Existing groundwater wells, listed in Table 1, have been used for gauging water levels and have been measured over time. Water level measurements are made with a water level indicator. The water level indicator signals at the top of water in the well and is measured with the tape at the top of the PVC well casing. The measured water level is subtracted from the surveyed well elevation to determine the groundwater elevation. LG Everist Fort Lupton GW Monitoring Plan MOLEN Page 4 of 7 29 L11 Groundwater Quality Monitoring Plan Water wells used for water level gauging are not used for groundwater quality sampling. However, the groundwater quality wells may be used for water level gauging. 3.2 Water Quality Monitoring Water quality monitoring wells are sampled ❑n a quarterly basis for at least five consecutive quarters, Water quality samples are collected from the WOM wells listed in Table 2, in accordance with the Groundwater Sampling Plan. Water quality samples are analyzed for the parameters listed in Table 3. Approved baseline water quality parameters are included in the water quality data collection. ❑nce baseline water quality data is obtained, all or only select number of water quality monitoring wells and parameters will be utilized for the collection of water quality data in the future. This GWMP includes parameters from the Colorado ❑epartment of Public Health and Environment (CDPHE) Reg 41 — Basic Standards for Groundwater Tables 1 through Table 4. The water quality sampling parameters are listed in Table 3 in Appendix I. LG Everist commits to obtain the water quality samples on a quarterly basis for five quarters prior to exposing water during mining. The water quality data will be used as a baseline, while subsequent water quality data, ❑btained annually, will be compared t❑ the baseline data to assess water quality variations. Parameters with significant non - detects or are determined to be unrelated to mining and/or mining activities may be petitioned to be omitted during the water quality assessment and only with ❑RMS approval. 4.0 WATER QUALITY EVALUATION The proposed water quality evaluation is based on statistical analysis, where the baseline data is compared to future samples. The date will be analyzed statistically to evaluate expected natural water quality variations within the aquifer. The statistical analysis is necessary to provide a means to evaluate the expected range of values in the representative baseline data, s❑ that when future samples are obtained, variations outside the statistical norms can then be evaluated regarding the potential of water quality degradation from mining activities. 4.1 Baseline Data Collection To initially evaluate the baseline data, a normal distribution and a 95 percent confidence interval around the mean will be used to establish a baseline range of values. This is standard statistical analysis commonly used for data management to establish an anticipated range of naturally occurring values that may occur in the aquifer. Water quality changes within the baseline data could be related to (a) seasonal variations, (b) changes in precipitation recharge, (c) spatial variations within an aquifer due t❑ heterogeneous geologic conditions and/or (d) changes in water levels and hydraulic LG Everist Fort Lupton GW Monitoring Plan MOLEN Page 5 of 7 30 L11 Groundwater Quality Monitoring Plan gradients with time that could affect water flow in the aquifer. Therefore, there may be a need to update the baseline data over time because the data has changed due to a particular change in natural conditions at the mining site. It may be impractical to conduct extensive statistical analysis on every water quality parameter tested. A set of select water quality parameters can be used to identify potential water quality degradation. This set of select parameters will be used for statistical analyses and charting and will be approved by DRMS in a TR. After the initial five quarters of baseline data is collected, future sampling will occur annually for the specific parameters. Prior to starting the mining, sampling will be conducted within 90 days. The water quality sample results from future sampling events during the mining activities will be compared to the baseline data. A further in-depth review of the groundwater quality data will be needed to determine whether mining is resulting in the potential for any type of pollution in the aquifer. 4.2 Sampling Parameters The sampling parameters listed in Table 3 are derived from CDPHE — Reg 41 Basic Standards for Groundwater, Tables 1 through Table 4. These parameters are analyzed for all baseline samples. The baseline sample data will be used to determine potential future changes in groundwater quality. 4.2.1 Selection of Parameters The groundwater data obtained from baseline sampling will provide information that can be used to determine the appropriate parameters for statistical analysis, and which parameters should be excluded in future sampling events. The proposed set of parameters will be determined after the baseline data is obtained. The set of parameters will be evaluated on an annual basis and if any anomalous trends develop for parameters, subsequent statistical analysis will be conducted to assess anomalous trends outside the expected naturally occurring water quality variability. 4.3 Statistical Analysis The database of sample analytical results will be preliminarily assessed for representativeness. Any anomalous, or non -representative, water quality data will be excluded from the baseline data prior to conducting the statistical analysis. If data points are excluded, LGE will provide a written rationale to the Division for the exclusion. Once the representative database has been established, the baseline mean and standard deviation for each of the selected parameters will be calculated. The data collected will provide the standard deviation used to establish a control limit (95 % confidence interval �.'77.`' LG Everist Fort Lupton GW Monitoring Plan '"I MO• LEN Page 6 of 7 31 L11 Groundwater Quality Monitoring Plan around the mean), beyond which any changes in water chemistry for that parameter will be assessed to evaluate if conditions in the mining area may be affecting ground water quality. It is proposed that "control charts" be constructed for each of the selected parameters in each of the water systems so that annual water quality data can be tracked to evaluate any potential trends in water quality. For all of the parameters there will be an upper control limit beyond which a significant change in ambient water quality can be assumed. It is also proposed that the stream standard for each of the selected parameters be shown on the control chart, as, for some parameters, stream standards may have already been exceeded in the background water quality, while, for other parameters, stream standards are above the expected range of natural variations in water chemistry. The control charts and statistical analysis are prepared on an annual basis as additional water quality data become available from additional sampling events. 5.0 VERIFICATION RE -SAMPLING Under certain circumstances a verification re -sampling may be collected, and samples submitted for analysis using the Groundwater Sampling Plan. The samples will be collected within four weeks of the analytical report date. A verification sample may be collected for the following sampling event depending on the frequency of sampling. Verification re -samples are designed to provide confirmation of the sample analytical data for sample result anomalies or statistical analysis. 6.0 REPORTING A report will be submitted to DRMS within 60 days after the fifth groundwater quality sample is collected. The report will include a summary of the data collected, statistical data, and a description of the assessment of data. Control charts are the preferred statistical method for presenting the data. The control charts will be done on all the data to date. Future sampling reports will be provided to DRMS on an annual basis or at another approved frequency. If confirmed exceedances of the statistical methods (control charts) are noted after regular annual sampling, a specific response plan will be prepared by LGE to address that issue. The specific response plan will include an evaluation of the number of selected parameters that show exceedances, the potential variability in the level of exceedances, and the duration of these exceedances. �J l MOLEN L LG Everist Fort Lupton GW Monitoring Plan Page 7 of 7 32 Figures Figure 1 — Monitoring Wells 33 L.G.

This document should be read in conjunction with all regulatory, work plan, orders, client -specific requirements, and other project -specific guidelines. 3.0 RESPONSIBILITIES 3.1 Sampling Personnel Sampling Personnel are responsible for sample collection, sample custody in the field, sample preservation, total and accurate completion of field and data sheets, field parameter measurements, sample delivery, and data delivery to the Project Manager, as described in this technical procedure. 3.2 Task Manager The Task Manager is responsible for supervising Sampling Personnel. Supervision includes ensuring that samples are collected, documented, preserved, field analyzed. handled and shipped or delivered to the appropriate laboratory as specified in project work documents and this technical procedure. 3.3 Project Manager The Project Manager is responsible for overall management of the project, sampling program design and implementation and providing any required clarifications in the use of this procedure. In most cases, the Project Manager will also fill the role of Task Manager. 4.0 GROUNDWATER SAMPLING PROCEDURES 4.1 Preparation for Sampling Following the determination of a sampling event date, sample bottles will be ordered from the contracted analytical laboratory. Sampling personnel will coordinate with the GLEN LG Everist Sampling Plan Page 2 of 10 41 Groundwater Quality Sampling Plan contracted lab so that sample bottles can be ordered in sufficient time for shipping, bottle inspection, and corrections. If any changes have been made to the site analyte list, the laboratory should be informed prior to bottle shipment. Sufficient sample bottles for each parameter group (total metals, anions, etc.) for each well will be verified upon receipt. Additional bottles for Quality Assurance/Quality Control (QAQC) samples (duplicates, trip blanks, field blanks, and/or equipment blanks) will also be arranged, as necessary, with the laboratory prior to shipment. The laboratory will also provide sample labels, chain -of -custody (COC) forms, and COC seals with delivery of the sample bottles. 4.2 Field Work Prior to Sampling Sampling personnel will inspect each well prior to sampling. The condition of the well casing, concrete pad, reference mark for water level measurements, protective steel casing, well identification markings, and security lock will be recorded. Additionally, the following will be recorded on a sampling data sheet (Appendix I) for each monitor well: • Observations made during visual inspection. • Static water level of well measured with electronic signal on measuring tape. • Total depth of the well measured or recorded from previous events. • Date and time of well measurements and well sampling • Purge water volumes calculated or rate of purging, if needed. • Observation of sample odor, presence of immiscible layers, and relative turbidity Prior to purging and groundwater sampling of any well, the static water level will be measured in the monitor well. The water levels for all the groundwater monitoring network wells will be measured on the same day or within a 36 -hour period of time. In addition to the water levels, total depth will be measured annually in all wells in the monitoring network. Water level and total depth measurements will be made to the nearest 0.01 foot from a dedicated reference mark on the riser pipe using a portable electric water level indicator and will be re -measured for consistency. Depths to water will be compared in the field to previous measurements to minimize the possibility of recording incorrect readings. To avoid potential cross -contamination. the water level probe and tape will be washed before the initial use and between well locations using an AlconoxTm/water solution followed by a rinse with distilled water, or use of a disposable alcohol water swab. A pair of new disposable gloves (nitrile or latex) will be worn while performing groundwater level measurements. If the total depth measurement indicates that 25% or more of the effective screen length of a well has become filled in with sediment, the well will be re -developed. Re- GLEN f. LG Everist Sampling Plan Page 3 of 10 42 Groundwater Quality Sampling Plan development will consist of purging a minimum of five casing volumes from the well, or purging the well dry twice if the yield is insufficient for continuous purging. In wells with sufficient yield, purging will continue until the sediment is removed and field parameters (pH, temperature, and conductivity) stabilize. Parameters are considered stabilized when there is less than a ±10 percent change in three consecutive measurements of temperature and conductivity, and pH readings are within ±0.2 standard units. For wells that purge dry, field parameters will be measured at the start and end of both purging cycles, if possible. The volume of water standing in each well will be calculated using the static water level measurement, the total depth of the well, and the casing diameter. One casing volume will be considered the water present in the well casing. Well depths for the purpose of well volume determination will be obtained from well completion records. The equation for calculation of one casing volume is: V = [TT x (r casing? X h] X 7.48 V = 0.16x h for a 2 inch well where: V= r casing = h = volume of water in well casing [gallons] radius of well casing [feet] height of water column (total well depth - depth to water) [feet] 4.3 Sample Collection 4.3.1 Decontamination All re -useable, non -dedicated sampling equipment will be decontaminated between each well location to provide representative samples. Decontamination will be performed by washing all equipment with an AlconoxTM/water solution followed by a rinse with distilled water. Water generated from decontamination procedures will be disposed of at least 20 feet from the well site. All clean or unused sampling equipment will be handled by personnel wearing new disposable gloves (e.g., nitrile or Iatex). After the re -useable sampling equipment has been decontaminated it will be wrapped in new clean plastic sheeting or placed in new clean plastic bags. The sampling equipment will remain in plastic sheeting or bags until it is used again at the next sampling event. 4.3.2 Sampling Equipment and Materials Purging and sampling equipment will consist of bailers and/or pumps. The bailers may be disposable or dedicated, and the pumps either dedicated or re -useable, to be decontaminated prior to each sample location, or dedicated. This GLEN LG Everist Sampling Plan Page 4 of 10 43 Groundwater Quality Sampling Plan equipment will be constructed of materials that will not alter the quality of the groundwater samples. Other sampling equipment may include the following: • Water level indicator; • Combination water quality meter for measuring pH, temperature, and conductivity; • Water quality meter calibration solutions; • Disposable gloves (nitrile, latex, or other appropriate material); • Distilled or deionized water; • Phosphate -free environmental detergent such as AlconoxTM; • Spray bottles for decontamination solution wash and rinse; • Peristaltic pump with associated tubing; • Battery or power for peristaltic pump; • 0.45 -micron filter(s) if field -filtering is necessary; • Plastic sheeting to prevent possible contamination of sampling equipment; • ZiplocTM freezer bags for sample storage and shipping; • Paper towels; • 5 -gallon plastic buckets for decontamination and purge volume measurement; • Sample bottles and sample preservatives; • Field forms including groundwater sampling data sheets, COC forms, and sample labels; • Coolers and ice. All of the groundwater purging and sampling equipment will be maintained in a clean and working condition. Sampling personnel will wear new disposable gloves while handling the sampling equipment that will be in contact with water samples. 4.3.3 Purging Prior to sample collection, each well will be purged of stagnant water using disposable or dedicated sampling equipment such as bailers and rope. Bailing will be performed at a rate that will minimize agitation of recovery waters and will continue until a minimum of three casing volumes have been purged and field parameters (pH, temperature, and conductivity) have stabilized, or the well is bailed dry. Field parameters will be measured at a frequency no greater than once per casing volume and purging will continue until there is less than ±10 percent change in three consecutive measurements of temperature and conductivity, and pH readings are within ±0.2 standard units. If a well is bailed dry before removing three casing volumes, sample collection will begin when a sufficient amount of groundwater has entered the well. In this situation, field parameters will be measured at the start of sample collection and again after sample collection is GLEN LG Everist Sampling Plan Page 5of10 44 Groundwater Quality Sampling Plan complete, if possible. The collection of these groundwater samples must be within 24 hours of purging. All field parameter measurements will be recorded on a field data sheet along with a description of the sample appearance at the time of field parameter measurement. The water quality meter used to measure field parameters will be calibrated according to manufacturer's recommendations prior to purging. Purge water generated during sampling events will be discharged on the ground, at least 20 feet from the well site, unless previous analyses have indicated that groundwater contamination has occurred at that well location. If previous analytical results indicate that groundwater contamination has occurred, purge water may need to be containerized and disposed of in accordance with state and federal regulations. 4.3.4 Withdrawal of Sample After purging is completed, sampling personnel will re -glove with new disposable gloves in preparation for sample collection. Sample containers will be filled based on parameter sensitivity to volatilization and pH change as follows: • Other organics (SOCs) • Dissolved Metals • Anions/Cations • Other inorganics and miscellaneous analytes Monitor wells will be sampled for analysis of the Regulation No. 41- The Basic Standards for Ground Water 5 CCR 1002-41, Colorado Department of Public Health and Environment Water Quality Control Division. Tables with parameters from the Reg 41 Standards are provided in Attachment 2. Portions of the list will be determined for specific sampling events and is limited to parameters listed in Table 1 through Table 4. Some low yield wells may produce insufficient volume to fill all of the sample containers within 24 hours of purging. Sample containers for these wells will be filled in the order listed above until the sample volume is depleted. Filled bottles will be submitted to the laboratory for limited analysis. VOC samples will be collected in 40 milliliter glass vials, SVOC and PAH samples will be collected in glass sample containers appropriate to the laboratory's analytical capability. Metals and other inorganic samples will be collected in plastic or glass containers of appropriate capacity. New sample containers with appropriate preservatives will be provided by the analytical laboratory. GLEN LG Everist Sampling Plan Page 6 of 10 45 Groundwater Quality Sampling Plan Every effort will be made to reduce contact between the bottles and sampling equipment. As an added precaution, contact time of the sample with ambient air will be minimized by replacing caps immediately after the bottles are filled. If VOC samples are collected, it will be done without air bubbles. This will be achieved by adding sample slowly until a convex meniscus form at the top of the vial (i.e., the vial is slightly overfilled) before replacing the cap. Once the cap is firmly attached, the vial will be inverted and examined for air bubbles. Metal samples will be field filtered when possible, utilizing a peristaltic pump and 0.45 -micron filters. Sometimes field filtering will not be possible, and samples will be submitted for laboratory for filtering prior to analysis. Following completion of groundwater sampling at each monitor well, all re- usable, non -dedicated sample equipment will be decontaminated in accordance with the procedures specified above in Section 4.2.1. 4.4 Sample Preservation, Handling, and Shipment Groundwater samples will be preserved as follows: • VOCs (if sampled) — hydrochloric acid (HCI) or no preservative • Dissolved Metals - none • Anions/Cations - none • Other organics and inorganics — none Preservatives will either be included with the sample containers in small vials or will be pre -added to the sample containers by the laboratory. If the preservatives need to be added to the sample containers, sampling personnel will place the specified volume of preservative to the container during the sampling. Sample filtration may need to be performed in the field or in the analytical laboratory. After sample collection, filled and capped containers will be wiped clean, appropriately labeled, and stored with ice or frozen icepacks in insulated coolers. Sufficient ice or icepacks will be added to the coolers to maintain sample temperatures at or below 4°C. Packing material will be added to the coolers as necessary to prevent breakage of glass containers when they are shipped. At the end of each day of sampling, collected samples will be delivered or shipped to the analytical laboratory. A completed and signed COC form will accompany all samples contained within the cooler. The COC will be kept preventing moisture damage and may need to be sealed inside a gallon -size ZiplocTm bag and placed in the cooler for shipment. If the sample cooler is shipped for overnight delivery, the cooler will be sealed GLEN LG Everist Sampling Plan Page 7 of 10 46 Groundwater Quality Sampling Plan with shipping tape and a signed COC seal, provided by the laboratory, will be affixed to the outside of the cooler. Sampling schedules and deliveries or shipments to the laboratory will be coordinated such that every attempt will be made to meet the recommended holding times of the analyses. Laboratory analyses performed outside the recommended holding times will be flagged or qualified appropriately in the report of analyses provided by the laboratory. 4.5 Chain -of -Custody of Samples EPA -accepted chain -of -custody (COC) procedures will be followed to maintain the validity of the groundwater samples being delivered to the laboratory. From the time the empty sample containers leave the laboratory until the issuing of the laboratory results, the samples and/or sample containers will be: 1) in sight of the assigned custodian, or 2) locked in a tamper proof location, or 3) sealed with a tamper proof seal. A written record of sample container possession and transference of samples will be documented on appropriate COC forms. The forms will also be used as a mechanism of communication between the sampling personnel and the analytical laboratory to note any specific details or requirements regarding the requested laboratory analysis. At the completion of the sampling event, a copy of the completed COC form, signed by all the appropriate entities handling the samples. will be retained with the laboratory report. 4.6 Quality Assurance and Quality Control Quality assurance (QA) and quality control (QC) procedures will be followed so that laboratory preparation, field sampling, and transport activities do not bias the results of the chemical analysis. QA/QC samples are collected to provide a quantitative basis for evaluating the analytical results. Typical QA/QC samples collected for groundwater sampling programs may include one or more of the following: Duplicate Sample - Duplicate samples are collected by the sampling personnel in a manner identical to the primary sample. The duplicate sample will be analyzed by the laboratory just as the primary sample is analyzed. The duplicate is intended to verify that the results from the primary sample are accurate and reproducible. Trip Blank - A trip blank consists of an analyte-free water sample prepared by the laboratory. The trip blank will accompany the sample container shipment from the laboratory to the field and back. At no time will the trip blank container(s) be opened in the field. Trip blanks will be analyzed by the laboratory only for volatile organic compounds. GLEN LG Everist Sampling Plan Page 8 of 10 47 Groundwater Quality Sampling Plan Field Blank - A field blank consists of empty sample bottles filled with distilled or deionized water at the sample site by sampling personnel. The field blank will also be analyzed by the laboratory as if it was a "real" sample. Equipment Blank - A variation of the field blank is the equipment blank. Equipment blanks are prepared in a manner identical to field blanks, except that distilled or deionized water is poured through clean (field decontaminated) sampling equipment and into the sample bottle. Equipment blank samples are analyzed for all analyses and are used to verify that sampling equipment is uncontaminated. At least one of the CIA/QC sample methods will be conducted every 4 sample events, one in four, during the first five years of sampling. 5.0 Analytical Procedures Volatile organic constituents (VOCs) will be analyzed in accordance with Method 8260 of EPA Report SW -846, Test Methods for Evaluating Solid Waste, while inorganic constituents will be analyzed by Method 6010 of SW -846, or other appropriate EPA methods. Reporting limits (RLs) for the parameters analyzed will be the lowest concentrations that can be reliably achieved within the specified limits of precision and accuracy during routine laboratory operating conditions and will be below any promulgated maximum contaminant levels (MCLs). Instrument detection limits will be kept at or below the RLs. Some analytical results may be reported below the RL and above the Method Detection Limit (MDL) with an estimated value. These results will be flagged, and the result determined as an estimate and not a reported value. 6.0 Analytical Data Review Upon receipt of the analytical results, general analytical data evaluation (i.e., data validation) will be performed. At a minimum, this evaluation will address the following: • Overall data completeness; • A review of laboratory qualified data; • Comparison of field duplicate results to original sample results; • Comparison of trip blank and method blank results to sample results; • Review of data accuracy based on cation -anion balances, etc.; and • Review of laboratory QA/QC sample results including comparison to spike recoveries to control limits. Results of the data review will be documented and used to initiate additional review by the laboratory or possibly addition qualifications of the analytical data by the reviewer.

Please refer to files for that information. All of the parcels not in the active mining operations have been actively farmed for many years. The crops grown were mostly corn, onions and alfalfa on the Parker Phases. A 200 foot band of undisturbed area will be maintained along the South Platte River. A 25 foot setback will be maintained from each side of the Little Dry Creek/Slate Ditch that bisects the Northwest phase from north to south. The Meadow Island Ditch/Lupton Bottoms East Lateral ditches run southeast to the northwest between the Northeast Phases leaving an undisturbed corridor across the Northeast Phase. The amendment area is mostly grass pasture in the Northeast Phases and irrigated crop or wetland areas in the Northwest Phase. There are no threatened or endangers species on the property. The closest eagles roost is located approximately 1550 feet east of the property and is outside the required seasonal setback areas suggested by the CPW guidelines. If new nests are observed in close proximity to the amendment area, LGE will investigate and take the necessary actions to prevent disturbance as outlined by CPW guidance. L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel 51 November, 2024 EXHIBIT I SOILS INFORMATION A new soils map is provided showing the entire permit area. The soils information currently in the file for this mine supply descriptions for most of the mined area soil types. But to get the information into one file, a new soils report was downloaded from the Web Soil Survey maintained by the NRCS. Soils on the amended north areas are consistent with the soils in the existing permit area with the exception for 2 new soil types located the Northwest Phase, the Vona loamy sands units 72 & 74 covering approximately 1.3% of the total area. As noted before, the soils on the Fort Lupton Sand and Gravel Mine site consists primarily of 2 soils types 3-Aquolls & Aquents gravely substratum and 41 -Nunn clay loam. They cover approximately 88% of the proposed permit area. These soils are primarily suited for pasture, rangeland and wildlife habitat. They are well suited to reestablishment of grasses as proposed in the Reclamation Plan. On average LGE has been able to salvage from 6 to 12 inches, averaging 8 inches of soil over the mined area for use in reclamation and have committed to replacing it on the areas to be revegetated to an average depth of 8 inches.

This amendment adds two areas adjacent to the north area with no changes to the southern area. Most of the amended acreage consists of agricultural land; however, some native vegetation occurs along Little Dry Creek and a section of wetland type area in the Northwest Phase that will not be mined. Overall, the new parcels have had a long history of intensive agricultural use including irrigated and non -irrigated crop and pasture land. The South Phases are still used as crop area with mostly corn, alfalfa and vegetables being grown this year. Vegetation Information Vegetation Type Descriptions - The following vegetation types were observed and mapped on the site. Pastures/agricultural crops Includes all of the amendment areas that consists of pastures developed for grazing livestock and an area on the west side that is planted with corn. The south area continues to be used to grow various irrigated crops ranging from corn and alfalfa to vegetables, like cabbage, beats, and squash. Disturbed Areas - Disturbed areas consist of the areas that are being mined and reclaimed south of Weld County Road 18. The disturbed areas also include sand and gravel processing plant areas, aggregate stockpile areas, internal haul roads, oil and gas wells and related production facilities and tank batteries and the like. There are 2 partially reclaimed Reservoirs that are being leak tested. Weedy species occur along the edges of the fields, irrigation ditches and along farm roads and temporary access roads that the farmers have not historically controlled. Riparian/Lowland/Wetland Areas - Riparian lowland areas occur along the South Platte adjacent to the east side of Blue Ribbon, the new amendment area in the Northeast Phases, and the Adam and Parker parcels. All of the riparian areas are located outside proposed mining areas. The areas are characterized by plains cottonwood and peach -leaved willow trees. Stands of coyote willow are also common. Due largely to past livestock grazing practices, the under story is relatively sparse and consists mainly of upland weeds. An approximately 15.37 acre area of wetlands have been identified north of Little Dry Creek in the Northwest Phase. This is characterized by standing water much of the year with cattails and other wetland plants. Part of this may be the result of an elevated water table caused by the reservoir liner built on adjoining property east of Little Dry Creek. No rare, threatened or endangered plant species are known to occur in the amendment area. The following NRCS table lists the typical native vegetation found on each soil type if it remains undisturbed. However, agricultural activities on all of the amendment area make this list only applicable for reclamation where the areas to be seeded will be rangeland. L.G. Everist, Inc. M-1999-120 Ft.

The applicant proposes leaving the bond amount unchanged as it would have adequate cushion to allow for development or the new area with out having to do an immediate reevaluation when mining moved into the Northeast #1 area. Current bond information: Fort Lupton Sand & Gravel Mine $ 2,002,400.00 The following recap explains the changes to the site that we have discussed in detail throughout this amendment application. These changes may affect the reclamation bond. The current conditions discussion following this section has tables showings the remaining activities to be used in estimating the financial warranty needs at this time. The applicant asks the Division to include the following items in its Circes© bonding calculations for this amendment: Bonding Decrease Reclamation Work completed (noted as of 10/21/2024) • Swingle North (2022,)Parker-Panowicz (2014) and Ft. Lupton West (2004) areas - slurry walls certified by the DWR (13,080'); • Swingle -South - installed slurry wall (Seal test in progress, 6400 ft) • Blue Ribbon - installed slurry wall (Seal test in progress, 5675' • backfilling, sloping and grading is done on Blue Ribbon, Swingle North and parts of Swingle south and Parker-Panowicz. Possible Bondincr Increase Installed slurry walls Sandstead - bond to install slurry wall (2945 ft) In conjuncLion wiLh Lhe installation of Lhe new slurry walls, there were necessary surface disturbances including (a) the working platform that is built for the equipment that is constructing the slurry wall, (b) areas where the material was taken from to construct the platform, and haul roads between the slurry wall platforms and the material gathering areas. These areas will need only grading and seeding. Mining in Existing area All of the areas currently in the mine are bonded for surface disturbance, liner installation and reclamation. Mining is complete in Parker-Panowicz, Swingle North and Blue Ribbon and all sloping is done. In Swingle South and Ft. Lupton West mining continues. Current Conditions This reclamation cost estimate is based on the assumption that at the current time no more then 300.00 acres will need some form of reclamation at any one time. Of this, 50.0 acres will be gravel surface area needing only grading, 59.0 acres requiring resoiling and seeding and there is 191.0 acres of future reservoir area that needs no work to reclaim. The 49.0 acre Plant Site in the L.G. Everist, Inc. M-1999-120 Ft. Lupton Sand and Gravel 88 November, 2024 EXHIBIT L RECLAMATION COSTS (cont) Ft. Lupton West phase on the Mining Plan Map - Exhibit C-1, the scale area in the Parker-Panowicz phase and a portion of the Swingle South area would need soiling and seeding to complete reclamation. There is sufficient amounts of growth medium in Swingle South to place 8 inches on the above water area in Parker- Panowicz, the above water area in Swingle south and on the Plant Site. The Tables L1, L2, and L3 contain all the base information used to calculate this estimate. The disturbed areas include, the plant site; roads; slurry wall construction pads and staging areas; gravel surfaces ❑n the above water areas around certified reservoirs and Blue Ribbon. Also the active mining areas that are stripped, partially mined or partially reclaimed areas. There are three, Division of Water Resources (DWR) certified slurry walls; two installed slurry walls (12,075 ft total) which are being tested for certification at this time and both are covered by the SWSP water; and 1 slurry wall (Sandstead) that will be installed in the next 2 years. The Sandstead slurry wall may be fully bonded as it is not installed yet. The slurry wall depths to bottom of the key trench and as built lengths are shown in the Table L3. We have included a factor of 20% for the 12,075 feet in those phases to cover remedial work on the completed liners until the DWR certification is received. The total potential water surface area in Swingle South, the only uncertified reservoir area needing sloping is estimated to be 37.3 acres at this time. Interior sloping is completed on the Blue Ribbon and approximately 50% of the Swingle South reservoir. The dewatering calculation for Swingle South is shown in Table L2 and Blue Ribbon would not need dewatering as all slopes are done in that area and Ft. Lupton West is a certified reservoir s❑ the slope could be built using the cut/fill method as the below water slope are dry at this time. We rounded the pumping time FOR Swingle South to the next day and used 72,300 gal/day as a transmissivity number to figure inflow from the aquifer. This figure is then used in the calculations for the bond amount. In this estimate we would have to complete bank backfilling on 3,040 linear feet at an average of 41.67 cyd/linear feet in Swingle South. The volume of concrete contained in the foundations of the scale and the processing plant is 125 yards. The conveyor is temporary and probable so only removal of 100 yards of concrete for the grade crossing ❑ver WCR 18 is included in the cost estimate. A 627C Cat motor scraper or similar equipment will be used to resoil the areas needing to be soiled and revegetated. A 140G Cat motor grader or similar equipment will be used to shape the seed bed, the resoiled areas, grade the graveled surfaces and rip the Plant Site. A D8N Cat dozer or similar equipment will be used to reconstruct the slopes around the perimeter of the reservoirs. Cut/fill sloping is need in the Plant Site active mining area as mining has not reached the reservoir area sides, L.G. Everist, Inc. M-1999-120 Ft.

Some inert materials, such as inert concrete or asphalt, will only be brought onto the site temporarily to be recycled (usually into road bases) and then sold. Some inert fill will be used to partially construct the slopes that will be left when mining ends. Some inert fill materials may also be used to backfill portions of the mined area. Some course inert fill may be used as bank armoring — and placed on slopes as per the permit's bank armoring plan. In some areas, the course inert fill materials may be covered with finer material and revegetated, as per the approved reclamation plans of the permit. If the inert fill material is an arable dirt which is suitable for growing grass or crops, we may use it to supplement the topsoil needs for the mined area. Reclamation sloping will not be delayed if inert fill is not available, because imported inert fill materials shall be supplemental to the materials already available on site for sloping, final grading and topsoiling. No specific compaction rates are proposed for the fill. The material usually available contains smaller pieces of concrete, or dirt mixed with larger pieces of the same material. When using mixed - size inert fill, specific compaction rates and stabilization of this fill material is not a concern because of the limited amount used in the slopes and the way it is placed. While we take no action to reach a specific compaction rate, the way the material is placed tends to compact it. We run heavy equipment over the area which is receiving the inert fill, and the material is compacted as a result. If any voids remain, they would be small and under large pieces of material, so very little settling is possible. No structures will be built on the fill, nor will the depth of the fill be so great as to affect offsite lands if settling occurred. The exact amount of inert fill material to be imported is unknown. We will record the volume imported each year and keep a running total so if needed, the Division will know how much and how it as disposed of. We will continue to import inert fill until reclamation is complete or we no longer have a source. (Affidavit on following page) 109 FL -DBMS -Inert Fill Notice-Nov2024 10.

Everist, Incorporated, being first duly sworn, deposes and says that the material to be imported into the mining operation known as the Fort Lupton Sand & Gravel will be inert material as defined in Mined Land Reclamation Board rule 1.1(20) listed below. At no time will material that does not meet this definition be imported to this site. M. L. R. B.

Everist, Inc Ft. Lupton Sand and Gravel BANK ARMORING PLAN This bank armoring plan is presented to explain the bank armoring and slope protection proposed for tw❑ mining phases that will be reclaimed as lined water storage reservoirs, and where mining will be within 400 feet of the western bank of the South Platte River. The bank armoring is intended to protect the finished slopes of the reservoir phases in case of a 100 -year flood event occurring after the phase has been reclaimed. The 100 -year Floodplain line information has been included on all of the MAP EXHIBITS in the application Packet. The two phases that have mining within 400 feet of the South Platte River are Northeast #1 and Northeast #3. The locations of the proposed bank armoring in these two phases are shown on MAP EXHIBIT F- RECLAMATION PLAN MAP. Northeast #1 Phase has approximately 1,030 feet of reservoir banks that will be armored, starting at the southeast corner and going north along the eastern perimeter. Northeast #3 has approximately 900 feet ❑f reservoir banks that will be armored, starting at the southeast corner and going north along the eastern perimeter. Armoring will only be installed on the inside banks of the reservoirs. Armoring will not be installed on the river bank itself because the river bank is 275 feet or farther from of the top of the slope of the mining limits, the river bank is outside the permit area, and it is not on land owned by L.G. Everist, Inc. Reservoir Bank Armoring Methods and Materials The finished reservoir banks in Northeast #1 and Northeast #3 will be armored as mining progresses through the Phase. The toe of the slope armoring will be at least 5 feet below the thalweg of the South Platte River channel. The base of the armoring will average 8 feet below the existing ground surface at the mine. The armoring will have a 3h to lv slope and will be 2 feet or more thick. This will leave an armored face along the top of the bank and the slope into the reservoir that is 35 feet wide. This will require approximately 2.35 cyd/lft, along the finished reservoir slopes. 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. After the larger material is placed, fines will be mixed in to fill voids. This size ❑f material has a Safety Factor ❑f 1.26. See the supporting document: BANK ARMORING PLAN -SAFETY FACTOR CALCULATIONS . The bank armoring materials will be installed on 2,000 foot sections of finished reservoir slopes within 3 to 6 months after sloping is completed. At a minimum, 4,700 cubic yards will be LGE - FT. LUPTON SAND AND GRAVEL November 2024 111 Ft. Lupton Sand and Gravel Rank Armoring Plan (cont) stockpiled, on the mine for use in armoring, which is enough to armor a 2,000 feet of finished bank slopes. At no time will there be more than 2,000 feet of armoring needing to be placed. Prior to installing the bank armoring, the stockpile of armoring materials will be placed in the setback area above the reservoir slopes so the materials can easily be pushed into place on the finished slopes. Any stockpiled materials will be placed parallel to possible water flows, so they will not interfere with water flows in the flood plain if flooding occurs.
