The entire site consists of approximately 114.25 acres. There are approximately 76 acres that LRM will utilize for mining. Approximately 38 acres of the site will consist of boundary offsets, perimeter buffering the main access road, the Big Thompson River corridor, and stormwater management areas. 6.1.1 Site Preparation The site will first be cleared of unneeded existing structures (old fencing and cattle chutes). The topsoil, if present, material will be stripped as each Cell is mined. Stripping will occur in phases or "strips" approximately 1/8th to 1/4th of the size of the Cell to expose the active mining area. The stripped material will be stockpiled adjacent to the active mining area. Scrapers, front-end loaders, excavators, and bulldozers may be used for stripping. Topsoil stockpiles, ditches and grading may be used to direct stormwater into the mining cells. Exhibit C shows the quantities of topsoil for each phase. A typical topsoil stockpile berm size will be 36 feet in width, 10 foot high, or 6.6 sq-yd per ft. The topsoil stockpiles will be stabilized, and erosion control devices will be installed. If the topsoil stockpiles will be in place for 180 days LRM will seed to produce a vegetated cover. An access bridge across the Big Thompson River will require a 404 Permit to construct. As part of the 404 Permit the bridge will be installed and analyzed to certify that it does not create a rise in the floodway. Haul roads will be established and stabilized during site preparation. Loveland Ready -Mix, Concrete, Inc. 6 updated_exhibits_d_220415. docx September 2021 TELESTO 6.1.2 Mining The sand and gravel deposit will be mined to bedrock. An excavator stationed on a moveable platform will be used to mine the material wet. The mining excavations will not be dewatered. The mining will be done in three Cells ranging in size from 11 to 36 acres, with excavation conducted to bedrock. A previous geotechnical report (C.E. Maguire Subsoil Exploration Report, 1978) and the recently installed groundwater monitoring wells have established the bedrock surface at approximately 28 to 30 feet below ground surface. Wet mining will be completed from a long -reach excavator stationed on a movable 16'x20' (minimum) platform. Because the material is mined "wet", mined slopes will be no steeper than 2H:1 V, consistent with slope stability calculations provided in Appendix B 1. The operator will develop and comply with a Stormwater Management Plan (SWMP). Berms and sloping of ditches will divert flow from all disturbed areas back into the mined cells. The operator will notify the Division of Mine Safety and Reclamation (DRMS) in the event of a reportable spill. Mined material will be stockpiled adjacent to the mining cells. The material will remain adjacent to the mining cell and drainage water will flow back to the mined cell. The material then will be loaded into haul trucks and transported offsite. 6.1.3 Imported Material Currently there are no plans to import material from other sites. Loveland Ready -Mix Concrete, Inc. (LRM) is aware that in accordance with Rule 3.1.5(9) of the Construction Materials Rules and Regulations, if any offsite material is used as backfill, a notarized letter will be submitted to the DRMS indicating the materials are inert. 6.2 Earthmoving Section 6.2 provides the information required by Sub -section 6.4.4(b) of the Rules and Regulations. Loveland Ready -Mix, Concrete, Inc. 7 updated_exhibits_d_220415. docx September 2021 TELESTO Topsoil will be excavated with front-end loaders, scrapers, or other similar equipment. The topsoil will be placed in berms at the edge of the active mine phase and stabilized as required. The construction material will be mined with an excavator stationed on a movable, 16'x20' (minimum) platform. The construction material will be transported offsite in 15 -ton tandem dump trucks. 6.3 All Water Diversions and Impoundments Sub -section 6.4.4(c) requirements of the Rules and Regulations are described in this section. The operator plans to mine the material wet; no dewatering activities are proposed. Stormwater that flows on to the site will be captured and contained in the cell(s) or allowed to flow through the site using historical channels in undisturbed portions of the site. Likewise, stormwater generated on site in disturbed areas will flow to the mining cells. Stormwater from the access road will be diverted back to the cell(s). The operator will develop and comply with a Stormwater Management Plan (SWMP). 6.4 Working Area Sub -section 6.4.4(d) of the Rules and Regulations requires a description of the size/areas of the mine to be worked at any one time. The proposed permit site will be divided into three cells and mined in phases. Cell 1 (C2) contains 36.7 acres, Cell 2 (C2) contains 10.9 acres, and Ce113 (C3) contains 28.3 acres. Exhibit C shows the progression of the mining phases through each cell. Table 1 shows cell sizes, aggregate, topsoil, and quantities for each cell.

The timetable establishes the relationship between mining and reclamation during the different phases of a mining operation. Mining operations are anticipated to begin soon after all permits are in place. The extraction rates are expected to be approximately 200,000 tons of construction material per year. Production rates will vary depending on market demands. LRM plans to conduct concurrent reclamation as mining progresses. Mining and reclamation are planned in five - acre increments. This will allow for safe and efficient operations with detail to slope stability and concurrent reclamation Exhibit C. Cell 1/C1 Mining will begin with Cell Cl for the first 10 to 12 years of operation. Approximately 37 acres will be mined in 7 phases during this time with a total of 2,166,145 tons of gravel. Cell 3/C3 Mining will continue into C3 and will last about 8 years. Cell C3 is approximately 28 acres, will be mined in 5 phases to the mining access road; mining will then begin at Cell 2. As Cell 2 is nearing completion, mining will recommence on Cell 3 along the west side of the access road working from north to south. Cell 3 will generate 1,717,639 tons of gravel. Cell 2/C2 Once mining reaches the access road from Cell 3, mining will be focused on Cell 2. Cell 2 will be conducted in 3 phases. Cell C2 is approximately 11 acres, will be mined in 4 phases and take a little over 3 years for a total of 661,565 tons of gravel. The operator will Loveland Ready -Mix, Concrete, Inc. 9 updated_exhibits_d_220415. docx September 2021 TELEST° comply with the performance standards of Section 3.1 and this operation is not intended to be an intermittent operation as defined in Section 34-32.5-103(11)(b), C.R.S. Reclamation and mining will be conducted concurrently when practicable to minimize disturbance and material handling. See the Mining Plan Map in Exhibit C for Cells and phases to be mined. 6.6 Deposit As described in Sub -section 6.4.4(f) of the Rules and Regulations, narrative and figures are provided in this section to describe the deposit. Figurel provides a generalized cross-section of the deposit. The deposit to be mined is the Big Thompson River alluvium, which consist of unconsolidated silt, sand, and gravels. The deposit ranges from approximately 25 to 28 feet thick and is overlain by approximately 1 to 2 feet of sandy to clay loam topsoil. A conceptual cross-section though the site is shown in Figure 1. The stratum below the target deposit consists of a weathered shale bedrock. 6.7 Commodities Sub -section 6.4.4(g) of the Rules and Regulations requires that the applicant identify the primary and secondary commodities to be mined/extracted and describe the intended use. The primary commodities to be mined are gravel, sand, and fill. The material will be used as aggregate in concrete and construction materials. 6.8 Incidental Products LRM does not plan to produce any incidental products, and thus, there is no information to report under Sub -section 6.4.4(h) of the Rules and Regulations.

The proposed mining and reclamation plan focuses on minimizing the ecological impacts of mining, minimizing the time of impact, and maximizing long term benefits. The Reclamation Plan describes all general requirements for the type of reclamation proposed to be implemented. These include: • Establishment of a natural/pasture offset along the property boundary with temporary berms for noise and visual impact mitigation, if needed • Seeding/vegetating overburden and topsoil stockpiles that will be exposed longer than 180 days • Implementation of stormwater diversion into mine cells • Backfilling and sloping sides of mining cells with excess topsoil, replacing topsoil • Seeding/vegetating final reclamation areas immediately after establishing reclamation grades • Mitigating impacted wetlands 7.1 Type(s) of Reclamation Proposed Section 7.1 provides the information required of Sub -section 6.4.5(2)(a) of the Rules and Regulations. The Dunn Pit will be returned to wildlife habitat with groundwater sourced ponds as each of the three phases is completed. See Exhibit F for acreages and details. LRM will establish new wetlands at various locations shown in Exhibit F-3. Approximately 2.55 acres of new wetland are possible. LRM is scheduling a preplanning meeting with the US Army Corps of Engineers to discuss the need for Section 404 permitting regarding the existing wetlands on site. Any subsequent 404 Permit approval and plan will be submitted to DRMS. Specific engineering, grading details, plantings, and timetables will be included with this plan and permit. For typical reclamation, as soon as practicable after an area is mined, topsoil will be pushed into place to cover disturbed areas slopes. Slopes of 3H:1V will be established from five feet above to ten feet below the average water surface, maximum slopes of 2H:1V will be established elsewhere around the reclaimed ponds. Topsoil will be placed over the Loveland Ready -Mix, Concrete, Inc. 12 updated_exhibits_e.docx September 2021 TELESTO disturbed area and the area will be seeded. The topsoil will be placed in a manner that controls erosion and siltation of the affected lands and areas outside the affected areas. The disturbed areas will be finished to a grade of 3H:1V that is suitable for revegetation. Service roads and the bridge crossing will remain in place so that rangeland maintenance equipment can access the site. Any areas that have been previously reclaimed that are not revegetating properly will be addressed and reseeded. 7.2 Post -Mining Land Use Comparison The historic land use in the vicinity of the Dunn Pit is agricultural, rural residential, recreational golf course, and oil and gas production. The pre -mining use of the affective lands is wildlife habitat. The post -mining land use of wildlife habitat, groundwater sourced ponds, and mitigated wetlands and open space will be compatible with the area. 7.3 Reclamation Plan Implementation Section 7.3 provides the information required of Sub -section 6.4.5(2)(c) in the Rules and Regulations. Mining of the Dunn Pit is proposed to be performed in three Cells ranging from 11 to 36 acres. During the mining of each proposed Cell, reclamation will commence concurrently following behind mining. All reclamation will be carried to completion with all reasonable diligence and each phase of reclamation with a goal to complete within five years from the date that each cell has been completed. As stated in this application, the mined areas are to be reclaimed to provide wildlife habitat, groundwater sourced ponds, or natural open space. 7.3.1 Reclamation Measures — Materials Handling 1. Final grading will be no steeper than 3H:1V from five feet above to ten feet below the average water surface, while maximum slopes of 2H:1 V will be established elsewhere around the reclaimed ponds. These reclaimed slopes will create final topography appropriate for natural open space or wildlife habitat. 2. No toxic or acid-forming materials are expected at this site 3. All grading will be done to control erosion and siltation of affected and non - Loveland Ready -Mix, Concrete, Inc. 13 updated_exhibits_e.docx September 2021 TELESTO affected lands. Off -site siltation is not expected but if it occurs BMPs will be used to control silt. Final grading will be no steeper than 3H:1V from five feet above to ten feet below the average water surface, while maximum slopes of 2H:1V will be established elsewhere. 4. Backfilling and grading will be concurrently behind mining as it progresses through each cell and will be completed as soon as practicable 5. Auger and drill holes that are part of the mining operation will be plugged with non-combustible material, which shall prevent harmful or polluting drainage. Monitoring wells and test pits no longer needed for the operation or monitoring will be plugged as soon as practicable 6. All mined material to be removed within the affected area will be handled in such a manner to prevent any unauthorized release of pollutants to the surface drainage system 7. No unauthorized releases of pollutants to the river or offsite will occur from any materials mined, handled or disposed of within the permit area. 7.3.2 Groundwater LRM will comply with all applicable Colorado water laws and regulations governing injury to existing water rights and will comply with all State and Federal water quality regulations. As described in Exhibit G, LRM plans to utilize the available water from their City of Loveland lease to replace depletions from exposed groundwater. LRM filed a substitute water supply plan with the Colorado Department of Natural Resources as required. There will be no discharges from site, and activities will not produce contaminants. Thus, groundwater quality is not anticipated to be an issue. Additionally, LRM will actively monitor site groundwater levels and work to mitigate unacceptable changes caused by mining activity or reclamation. 7.3.3 Wildlife The reclamation and mining plans have been structured to minimize impacts to wildlife. By mining and reclaiming each cell simultaneously, the impact to wildlife will be minimized. Wildlife habitat should be improved by the addition of the groundwater source ponds and revegetation of the banks. The proposed grass seed mix will return cover for wildlife adjacent to the ponds. Loveland Ready -Mix, Concrete, Inc. 14 updated_exhibits_e.docx September 2021 TELESTO 7.3.4 Topsoil Topsoil will be removed and stockpiled in berms around the perimeter of the area being mined. The topsoil berms will be out of the way of the active mining operation and will be near the areas where topsoil will be placed during reclamation. The stockpiles that will remain in place for more than 180 days will be seeded to stabilize them and minimize erosion. 7.3.5 Revegetation The reclaimed areas will be seeded with a grass mix that will be like and compatible with the grass species in the area. The vegetation will be capable of self -regeneration without continued dependence on irrigation or fertilizer. Any wetland mitigation will involve specific seed mixes of approved wetland sod. These may include bull rush, spike rush, and scripts validus. In addition to seeding, LRM plans to plant trees and shrubs in key locations to block sound, dust and mitigate potential erosion. These planting locations are shown in in Exhibit F. 7.3.6 Buildings and Structures Prior to mining, LRM plans to demolish dilapidated fences and structures. LRM will appropriately dispose of the debris and salvage materials of value. No buildings will exist on site after reclamation. 7.3.7 Signs and Markers Appropriate signage, indicating that the area is under reclamation, will be posted at the entrance to the mine site. The permit area will be marked by existing fencing with signage. Once reclamation is established, signage will be replaced with appropriate "No Trespassing" signs. 7.4 Topsoil Management and Revegetation This section provides the information required by the Rules and Regulations, Sub -section 6.4.5(2)(d). Loveland Ready -Mix, Concrete, Inc. 15 updated_exhibits_e.docx September 2021 TELESTO 7.4.1 Topsoil Management 7.4.2 Revegetation LRM plans to utilize the seed mixture presented in Attachment 4 of the response to adequacy review as the basis for reclamation seeding mixtures (Pawnee Butte Seed, 2017). Placed topsoil will be graded to drain, scarified to promote infiltration and air movement into the soil. Seeding will be accomplished by broadcast or drill. Broadcast seeding will be followed by dragging, or light rolling to promote soil contact. Drill seeding will be at the appropriate depth in the soil to optimize germination for the species being planted. In general, seeds should be placed 1/4 inch to 1/2 inch deep in the soil. Following seeding, areas will be protected from erosion by the application of cereal straw or grass mulch, laid and crimped into the soil as to prevent removal by wind and water. Grass or straw will be crimped in place with a mechanical crimper made for such purposes or using a farm -type disc plow set straight with adequate weight to crimp the material to a depth of approximately 4 inches. Mulch will be applied at a minimum rate of approximately one ton per acre. For slopes exceeding 5:1, mulch will be applied at a minimum rate of approximately 2 tons per acre. LRM plans to utilize a diverse grass species that are best adapted for this area based on recommendation from Pawnee Butte Seed Company (Pawnee Butte Seed, 2017). A minimum of four species will be specified for mixes and a mix of cool and warm weather species are included. Attachment 4 of the response to adequacy review shows the temporary soil stockpile, upland and wetland seed mixes. 7.5 Reclamation Schedule For information satisfying Sub -section 6.4.5(2)(e) of the Rules and Regulations, please refer to the timetable for mining and reclamation in Exhibit D Section (e). Also shown in Exhibits D and F are the size and location of each mining Cell/phase's reclamation area. The sequence of reclamation is described in the previous sections and shown in Exhibits C and F. Loveland Ready -Mix, Concrete, Inc. 16 updated_exhibits_e.docx September 2021 TELESTO 8.0 EXHIBIT F - RECLAMATION PLAN MAP Sub -section 6.4.6(a) requires a map(s) of the proposed affected land, by all phases of the total scope of the mining operation indicating the following: • The expected physical appearance of the area of the affected land • Correlation of appearances to the proposed mining and reclamation timetables • Proposed topography of the area with contour lines of sufficient detail to portray the direction and rate of slope of all reclaimed surface • Portrayal of the proposed final land use for each portion of the affected lands Exhibits F-1 and F-2 in the Plates at the end of this report provide an example of the concurrent mining and reclamation utilizing the first 10 -acres of Cell 1. LRM will continue mining and reclaiming the cells in the sequence shown in Exhibit C. Exhibit F-3 (also in the Plates at the end of the report) portrays the final site reclamation disposition of the site. Exhibit F-4 shows LRM's shrubbery and tree landscaping plan, most of which will take place prior to mining, while Exhibit F-5 provides a schematic of the final reclamation vegetation distribution. LRM plans to begin reclamation of the wetland area in Cell 1 within 2 years after start of mining and then follow behind mining with concurrent reclamation. When mining starts in Cell 3, Cell 1 will be at reclamation slope with approximately 90% of the topsoil placed and seeded. Based upon mining and reclamation plan, the maximum amount of reclamation to be completed at any one time is approximately one -to -two -acre average, with 15,000 average cy of stockpiled topsoil. Loveland Ready -Mix, Concrete, Inc. 18 30310913_master_applicatiou_Irm_dunnpit_fival draft.docx September 2021 TELEST° 9.0 EXHIBIT G —WATER INFORMATION Sub -Section 6.4.7(1) requires a statement of the direct impacts to surface and groundwater systems. Sub -Section 6.4.7(2)(a) describes water features to include on a map. Sub- sections 6.4.7(2)(b) require identification of all known aquifers. Sub -Section 6.4.7(2)(c) requires that LRM show how water from mining operations or runoff from disturbed areas, piled material and operating surfaces will be managed to protect against pollution of either surface or groundwater both during and after the operation. 9.1 Effects to Groundwater and Surface Water Water management of the Dunn Pit will not affect surface or groundwater quality as all surface water gradients during operation will be towards the pits. After reclamation, surface water will continue to report to the interior of the site. Because of the wet mining operation, there will be no dewatering, and therefore, minimal impact to groundwater levels adjacent to the site. The SWSP request submitted to the Division of Water Resources State Engineers Office and included in Appendix C addresses the exposure of groundwater; related evaporative depletions; and water consumed with the mining process. 9.2 Water Pertinences The area has several natural streams and man-made water infrastructure. Recorded features within 200 feet of the property perimeter are listed in this section. Water rights structures (Name and WDID) are shown in Figure 2. 9.2.1 Decreed surface water features • Big Thompson River (00202019) • Hill and Brush Ditch (0400522) 9.2.2 Decreed groundwater features • Milliken Augmentation (0402511) • Mad Russian Well (0405661) Loveland Ready -Mix, Concrete, Inc. 19 30310913_master_application_Inn_drompit_final draft.docx September 2021 TELESTO 3177000 3173000 3174000 3175000 3176000 0 0 0 N. 0 0 0 0 N. 0 0 0 0 coa oq to , O a LL AGRICULTURAL FIELDS MW -03 OUTBUILDINGS WETLAND -5 WETLAND -4 WETL ND -2 WETLAND -1 WETLAND -6 RAILROAD RIGHT-OF-WAY WETLAND -7 WETLAND -15 WETLAND -10' OUTBUILDINGS Mad Russian (59968-F) (No Well Construction Found COUNTY RIGHT-OF-WAY HIGHWAY RIGHT-OF-WAY • LEGEND WETLAND MONITORING WELLS () PERMITTED NEIGHBOR WELLS EXISTING 100 -YEAR INUNDATION BOUNDARY �. .

Figure 2 reflects no well constructed. • Site investigation shows no Hall Irwin well (248398) located where the DWR Map Viewer locates Hall Irwin well. This was likely mis-recorded in the DWR database. 9.3 Known Aquifers The Project area is underlain by the Big Thompson Alluvial aquifer. The Laramie -Fox Hills aquifer is known to exist in the area between the alluvium and the Pierre shale formation. More information on aquifers can be found in the groundwater study report (Telesto, 2021) provided in Appendix D of this application. 9.4 Water Quality Management Sub -section 6.4.7(2)(c) of the Rules and Regulations require that LMR show how water from mining operations or runoff from disturbed areas, piled material and operating surfaces will be managed to protect against pollution of either surface or groundwater both during and after the operation. As described in Exhibit D, LRM plans to capture all stormwater produced on the site and that which currently runs on to the site. The mining of material will be conducted "wet; no dewatering is proposed. The use of berms and ditches to divert water to the cells will be implemented. Additional information is provided in the (Telesto, 2021) and groundwater study (Telesto, 2021). 9.5 Water Requirements As described by Sub -section 6.4.7(3) of the Rules and Regulations, this section describes the estimated project water depletion that may occur for the development, mining and reclamation phases of the project. No dewatering is proposed for this mining operation. Loveland Ready -Mix, Concrete, Inc. 21 30310913_master_applicatiou_Irm_dunnpit_fival draft.docx September 2021 TELEST° LRM reuses water and thus, water consumption is limited to evaporative processes. Table 4 summarizes the predicted annual average consumptive use of water. Table 4 Item Yearly Amount (Acre -Feet) Comments Gravel Pit Evaporation 13.9 Lost to evaporation Dust Control Evaporation 1.41 Lost to evaporation Water Entrained in Aggregate 3.96 Lost to evaporation Depletions at river (seep to pit) 15.46 Lost to evaporation Total 34.73 Total consumptive use Predicted Consumptive Water Use At reclamation, LRM plans to utilize grasses, low water self-sustaining trees and shrubs, and thus, does not anticipate utilizing water for reclamation irrigation in the mined areas. 9.6 Water Supply Sources Sub -section 6.4.7(4) of the Rules and Regulations requires that LRM indicate the projected amounts of the water sources to supply project water requirements. This section provides a general description of the planned water sources to offset the consumptive use of the proj ect. LRM plans to replace its consumptive use through a Substitute Water Supply Plan, which will be reviewed and approved by the State Engineer's Office (SEO). The Dunn Pit will be registered as a well with the State Engineer's Office and utilized as a primary source (LRM has submitted an application). Additionally, captured stormwater will be utilized in the operations. An approved engineering analysis will determine the monthly depletions to the river so that these depletions can be replaced with water acquired through either a long-term lease, purchase, change of use, or exchange. LRM currently has a sufficient quantity of leased City of Loveland effluent water to replace consumptive use associated with the project. In addition to the City of Loveland leased effluent, LRM has changed Hillsborough Ditch shares, and lined storage upstream as approved in 2009CW105. As documented in Section 5.3 of the decree the changed Hillsborough shares are also authorized for augmentation purposes to replace evaporation Loveland Ready -Mix, Concrete, Inc. 22 30310913_master_application_Inn_drompit_final draft.docx September 2021 TELEST° from unlined gravel pits and other depletions resulting from reclamation, and production pursuant to an approved substitute water supply plan or a decreed augmentation plan at the Dunn site. 9.7 NPDES Permit A National Pollutant Discharge Elimination System (NPDES) permit from the Water Quality Control Division will not be required. This statement satisfies Sub -section 6.4.7(5) of the Rules and Regulations. Additional information in this regard follows: The Dunn Pit project is designed to be a zero -discharge facility with stormwater directed internally to the onsite control measures. Because the project is designed as a zero - discharge facility, LRM does not need a Certificate to Discharge under the Colorado Discharge Permit System CDPS General Permit Number 500000. Loveland Ready -Mix, Concrete, Inc. 23 30310913_master_applicatiou_Irm_dunnpit_fival draft.docx September 2021 TELEST° 10.0 EXHIBIT H - WILDLIFE INFORMATION This exhibit provides the information required by Sub -section 6.4.8 of the Rules and Regulations, which evaluates significant wildlife resources. LRM is committed to developing the sand and gravel mineral resource with wildlife in mind. Assessment of wildlife corridor(s) is a key component. The main focus on a corridor is the Big Thompson River and adjacent vegetation and wetlands. Local topography and vegetation (and tree line) may be used to help create visual barriers to minimize disturbances to local wildlife. By limiting the extent of mining through phases in each mining cell and concurrent reclamation, disturbance to the site will be limited. The proposed reseeding and landscaping (reclamation) which includes shrubs and trees, as well as controlling noxious weeds and creating wetlands can benefit wildlife. LRM will implement proper trash collection and utilize animal -proof containers. Containers will be secure with tight -fitting lids. If fences are necessary, fencing design should consider relatively free movement of wildlife. The feeding of wildlife on location will not be tolerated; injured wildlife will be left alone and the CPW office notified. LRM will engage CPW if there are any conflicts or issues involving wildlife. CPW has a Northeast region office located in nearby Fort Collins (970.472.4300). 10.1 Existing Wildlife Resources Sub -section 6.4.8(1)(a) of the Rules and Regulations requires a description of the significant wildlife resources on the affected land, which is summarized in this section. Telesto Solutions, Inc. (Telesto) conducted a desktop review for federally listed species and their critical habitats, if designated. Federally listed species with potential to occur within Weld County, Colorado were identified using a U.S. Fish and Wildlife Service (USFWS) Information, Planning and Conservation System (IPaC) search and the associated IPaC Trust Resources Report (USFWS, 2020). The IPaC search identified protected and sensitive plant and animal species with potential to occur in the project area. Loveland Ready -Mix, Concrete, Inc. 24 30310913_master_application_Inn_drompit_final draft.docx September 2021 TELEST° In total five (5) species are listed and threatened or endangered for the project area (Table 5). The IPaC Trust Resources Report confirms that no critical habitats exist within the project area. Table 5 Species Scientific Name Federal Status Birds Eastern Black Rail Laterallus jamaicensis ssp. Jamaicensis Threatened Flowering Plants Ute Ladies' -tresses Spiranthes diluvialis Threatened Western Prairie Fringed Orchid Platanthera praeclara Threatened Mammals Black -footed Ferret Mustela nigripes Endangered Preble's Meadow Jumping Mouse Zapus Hudsonius preblei Threatened Sensitive Plants and Animals 10.2 Migratory Use Sub -section 6.4.8(1)(b) of the Rules and Regulations require an analysis of the potential seasonal use of the area by wildlife. 10.2.1 Migratory Bird Treaty Act The USFWS provides protection to native avian species under the Migratory Bird Treaty Act (MBTA). The MBTA makes it illegal for anyone to take, possess, import, export, transport, sell, purchase, barter or offer for sale, any migratory bird, or the parts, nests, or eggs of such a bird, except under the terms of a valid permit issued by the USFWS. Several avian species protected by the MTBA, including raptors, are likely to occur within the project area. Potential nesting habitat is present within the project area along the Big Thompson River which bisects the project area. The scattered trees of the project area offer opportunities for Swainson's hawk (B. swainsonii), and possibly, red -tail hawk (Buteo jamaicensis) nesting. Trees of ample size to provide nesting opportunity for raptors are located along the Big Thompson River. The activity of the Dunn Pit will allow a buffer of nonactivity along the Big Thompson River. Feeding and scavenging activities of the Turkey vulture (Cathartes aura) are likely to occur in and around the project area. Nesting activity is unlikely due to elevated levels of activity adjacent to the project area. During periodic site inspections by Telesto personnel, no nesting activity was detected within the trees located inside the project area. To ensure consistency with the requirements of the Loveland Ready -Mix, Concrete, Inc. 25 30310913_master_application_Inn_drompit_final draft.docx September 2021 TELESTO MBTA, all trees within the project area will be considered as suitable nesting habitat for migratory birds subject to the protection of the MTBA. Ground nesting activity is highly unlikely due to historic, sustained agricultural uses including livestock grazing and limited oil and gas production. 10.2.2 Bald and Golden Eagle Protection Act Bald eagles (Haliaeetus leucocephalus) and golden eagles (Aquila chysaetos) are protected under the Bald and Golden Eagle protection act. Both species may pass through the project area when traveling to areas of more suitable foraging or nesting habitats. The nearest active nest identified by Colorado Parks and Wildlife (CPW) is approximately 1 mile west- northwest of the project area. 10.2.3 Raptor Nest sites The CPW has developed a set of guidelines to avoid or minimize disturbance to nesting, wintering, and resident raptors. Based upon the identification of a raptor or raptor's activity in the area, CPW welcomes consultation and has provided "recommended" buffer zones and seasonal restrictions or stipulations. Telesto conducted site surveys and cross -agency reviews for raptor activity on the proposed Dunn Pit location. No raptor nests existing within the project area were observed. Raptor activity was not noted. The nearest observed activity was noted through the Colorado Oil and Gas Conservation Commission (COGCC) mapping tool of an active bald eagle nest approximately 1 mile west-northwest of the site. The COGCC mapping tool is tied into the current CPW data; data does not indicate the presence of any active raptor nests within a '/z mile radius to the project area. Physical raptor surveys could not be completed on adjacent, privately owned lands due to access issues. 10.2.4 Winter Night Roost Due to the absence of raptor nests in the project area, it is unlikely this project would be impacted by adjacent wintertime night roosts. Further, this facility is unlikely to be in operation during nighttime hours, especially during the winter months. Loveland Ready -Mix, Concrete, Inc. 26 30310913_master_application_Inn_drompit_final draft.docx September 2021 TELESTO 10.2.5 Nest Survey Due in part to a lack of access agreements for the adjacent private lands, Telesto did not conduct formal species -specific surveys for an ESA -listed or MBTA-protected species during the site investigation, although signs of such species (e.g. old nests) and ESA species' habitats were not observed within or around the project area, and would have been recorded if present. Trees within the visual line of sight of the project area with the potential to support raptor nests were inspected from the project area using binoculars and visual aids and no raptor nests were observed. 10.3 Threatened and Endangered Species To comply with Sub -section 6.4.8(1)(c) Rules and Regulations, which requires an assessment of the presence and estimated population of threatened or endangered species, the following summary of the desktop review is provided. The USFWS notes that three federally threatened species and one endangered species are known or suspected of being within the vicinity of the project area: 1) the Preble's meadow jumping mouse (Zapus hudsonius preblei), 2) Eastern Black Rail (Laterallus jamaicensis ssp. Jamaicensis), and 3) Ute ladies' tresses orchid (Spiranthes diluvialis). In keeping with the USFWS observations, detailed discussion about Threatened and Endangered Species will be limited to these three species. The Western Prairie Fringed orchid (Platanthera praeclara) also referred to as "Platte River Species", is listed under the Endangered Species Act due to concerns over the impact of water depletions on downstream populations and critical habitat within the Platte River drainage. The project area is adjacent to the Big Thompson River tributary to the South Platte River and thus, the potential for connectivity to the Platte River was considered. No effects or depletions of the Platte River are expected to arise from this project; therefore, no downstream affects are expected to the Platte River species and no further discussion is warranted. The Black -footed ferret (Mustela nigripes) is listed under the Endangered Species Act due to concerns with depletions to critical habitat. The habitat of the ferret Loveland Ready -Mix, Concrete, Inc. 27 30310913_master_application_Inn_drompit_final draft.docx September 2021 TELESTO includes the presence of a prairie dog colony and continued food source. CPW and the USFWS have not observed the ferret in this area and no further discussion is warranted. 10.3.1 Preble's Meadow Jumping Mouse The Prebles's meadow jumping mouse is generally found within the Platte and Arkansas River drainages of Colorado. This species prefers heavily vegetated, shrub -dominated riparian habitats and immediately adjacent undisturbed grass land communities up to 100 meters beyond the suitable riparian habitat. The project area is within the USFWS' identified overall range for the mouse. However, the project area is not within any designated critical habitat for the Preble's meadow jumping mouse. The project area is also unlikely to contain primary habitat for the Preble's meadow jumping mouse. The Big Thompson River bisects the project area and could potentially support migratory behavior of the Preble's meadow jumping mouse. However, the project area is dominated by grass pasture fields subject to continuous agricultural activity (grazing) and is almost devoid of the shrubby habitat preferred by the Preble's meadow jumping mouse. The vegetation within the project area is subject to disturbance to cattle and horse grazing and mowing activities year-round. Consequently, the project area generally does not conform to the habitat preferences and requirements for the Preble's Meadow Jumping Mouse, and any negative impacts to the mouse are very unlikely. There have been not recorded observation of the mouse within the project area. These observations are confirmed by the IPaC Trust Resources Report (USFWS, 2016), which indicates no critical habitat exists within the project area. 10.3.2 Eastern Black Rail One of four subspecies of black rail, the eastern black rail is broadly distributed, living in salt and freshwater marshes in portions of the United States, Central America, and South America. Partially migratory, the eastern subspecies winters in the southern part of its breeding range. The California black rail subspecies (Laterallus jamaicensis coturniculus) is confined to central and southern California, western Arizona, and Mexico. The two other subspecies of black rail, Laterallus jamaicensis murivagans and Laterallus jamaicensis salinasi, occur in South America in the countries of Peru, Chile, and Argentina. Loveland Ready -Mix, Concrete, Inc. 28 30310913_master_application_Inn_drompit_final draft.docx September 2021 TELESTO The U.S. Fish and Wildlife Service (Service) was petitioned in April 2010 to list the eastern black rail as an endangered or threatened species under the Endangered Species Act (ESA). In September 2011, the Service published a 90 -day finding that the petitioned action may be warranted and initiated a review of the subspecies. A 12 -month finding based on that review was delivered to the Federal Register proposing to list the eastern black rail as a threatened species. No habitat of a marsh is located at or near the Dunn Pit project area and there are no records of the Eastern Black Rail species within the immediate region. 10.3.3 Ute Ladies' Tresses Orchid Ute ladies' -tresses primarily occupy moist, irrigated or seasonally flooded soils in valley bottoms, gravel bars, old oxbows, or floodplains bordering springs, lakes, rivers, or perennial streams at elevations between 1,800 to 6,800 feet above mean sea level. Some occurrences have been found in agricultural lands managed for winter or early season grazing or hay production. Known sites offer low vegetative cover and may be subjected to periodic disturbances, such as flooding or grazing. The project area is within the range for the species but no suitable habitat was observed and the Ute Ladies' tresses is unlikely to occur in the project area. Historic and consistent agricultural activities within the project area spanning several decades likely preclude the presence of the Ute Ladies' tresses orchid and no critical habitat designation has been made (USFWS, 2016). 10.4 Effects on Existing Wildlife A description of the general effect during and after the proposed operation on the existing wildlife of the area is described in this section in order to comply with the requirements of Sub -section 6.4.8(1)(d) of the Rules and Regulations. Potential impacts to wildlife from the proposed mine are expected to be minimal due to the preexisting disturbed nature of project area. Historical agricultural activities, oil and gas exploration, a railroad easement, and residential and commercial development are active in the vicinity of the proposed Dunn Pit. Project activities may cause minor disruption to Loveland Ready -Mix, Concrete, Inc. 29 30310913_master_application_Inn_drompit_final draft.docx September 2021 TELESTO foraging or localized migratory movement of certain species, but wildlife currently utilizing the area are expected to migrate to undisturbed areas along the Big Thompson River and adjacent to the project area. No direct losses of wildlife are expected as result of the project. Upon reclamation, wildlife habitat should be improved due to the conversion of existing pastureland to enhanced groundwater sourced ponds and the maintenance of the environment to shelter and cover for wildlife. Loveland Ready -Mix, Concrete, Inc. 30 30310913_master_applicatiou_Irm_dunnpit_fival draft.docx September 2021 TELEST° 11.0 EXHIBIT I - SOILS INFORMATION The information provided in this exhibit is intended to satisfy the requirements outlined in Section 6.4.9 of the Rules and Regulations. The soil units within the project area, as mapped by the National Resource Conservation Service (MRCS), are depicted in Figure 3 and Table 6. The site soils range in thickness from 0.5 to 30 feet (confirmed by soil borings). The soils have been under livestock grazing since the mid -1900s and thus, are conducive to plant growth and suitable for reclamation purposes.

The representative classification is shown here for the surface layer of the soil. In this table, ML = silt; SM = silty sand; SC = clayey sand; GC = clayey gravel; GM = silty gravel; and CL = clay of low plasticity. b Soil pH is a measure of acidity or alkalinity. Available water capacity is the volume of water available to plants if the soil, inclusive of rock fragments, were at field capacity, reported in centimeters of water per centimeter of soil (cm/cm). Soil properties that affect the retention of water include organic content, soil texture, bulk density, and soil structure, with corrections for salinity and rock fragments. d.Ksat reflects soil characteristics such as structure, porosity, and texture. e The content of sand, silt, and clay affects the physical behavior of a soil. Particle size is important for engineering interpretations, for determination of soil hydrologic qualities, and for soil classification. (Plasticity index (PI) is one of the standard Atterberg limits used to indicate the plasticity characteristics of a soil. It is defined as the numerical difference between the liquid limit and plastic limit of the soil. It is the range of water content in which a soil exhibits the characteristics of a plastic solid. g Liquid limit (LL) is one of the standard Atterberg limits used to indicate the plasticity characteristics of a soil. Generally, the amount of clay- and silt -size particles, the organic matter content, and the type of minerals determine the liquid limit. Soils that have a high liquid limit have the capacity to hold a lot of water while maintaining a plastic or semisolid state.

It meets the requirements of Sub -section 6.4.10(1)(a) of the Rules and Regulations. Vegetation within the project area consists largely of native grasses including blue gramma, buffalo grass, needle and thread grasses, and western wheat grass. Minor noxious weeds (such as thistle and cheat grass) are scattered or isolated on the property. Large cottonwood (Populus deltoids), peach -leaf willow (Salix amygdaloides), alder (Alnus spp.) and other short-lived trees such as elm are located primarily along the Big Thompson River and other isolated locations. Trees range in height from 6 to 30 feet in height and tend to be congregated along the fluvial influence of the Big Thompson River and western -central portion of the property. Intermittent low shrubs include alder (Alnus spp.) also exist and range in height from 2 to 6 feet. Forbs scattered through the project area include goldenrod (Solidago spp.). The dominant vegetation type, blue gramma, buffalo grass, needle and thread grasses, and western wheat grass, varies in height from 3 inches to 8 inches, depending on recent grazing activities. Common weeds and invasive species observed include Common thistle (Cirsium vulgare), Canada thistle (Cirsium arvense), field bindweed (Convulvus arvensis L.) and common dandelion (Taraxacum officinale). Overall cover is dense and is estimated at 95 percent. A wetland delineation/determination was conducted on behalf of LRM for the Dunn Pit location. Wetland delineation establishes the existence (location) and physical limits (size) of a wetland for purposes of federal, state, and local regulations. Wetland delineation is Loveland Ready -Mix, Concrete, Inc. 33 30310913_master_application_Inn_drompit_final draft.docx September 2021 TELEST° also an element of a jurisdictional determination. This process identifies which water bodies within a project's boundaries meet the definition of "waters of the United States". LRM is committed to working with the U. S Army Corp of Engineers to draft a mitigation plan compatible to the conceptual mining plan if necessary (Telesto, 2021). Results of this delineation confirm 3.03 acres of potential jurisdictional wetlands and 1.46 acres of WOUS occur within the Project Area but only a fraction will be disturbed. The USACE has the overall authority to confirm the regulatory status of surface water features identified by this delineation that abut or are isolated from the Big Thompson River and provide a determination that identifies all regulated wetlands and WOUS within the Project Area. Section 404 permitting requirements are driven by the total amount and type of permanent impacts on regulated surface water features. Project impacts that exceed 0.5 acres typically require a Section 404 Individual Permit, while impacts below 0.5 acres may qualify for a Nationwide Section 404 permit. The appropriate permit requirements are determined by overlying the project design on the delineation map to identify impacts on potential regulated surface water features. Once potential impacts are identified, a preapplication meeting with the USACE is recommended to confirm Section 404 permit requirements. 12.2 Soils and Vegetation Sub -Section 6.4.10(1)(b) of the Rules and regulations requires the following description of the relationships of present vegetation types to soil types. The soil types described in Table 6 are consistent with current use as dryland grazing pasture grass. The Theduland loam are categorized by the NRCS as prime farmland, if irrigated. The NRCS does not describe the Aquolls and Aquents gravelly substratum prime farmland. The trees and shrubs within the project area are almost exclusively confined to limited irrigated areas and along the riparian corridor of the Big Thompson River. Onsite evaluation of present vegetation exhibit a uniform use of the land as grazing pasture for livestock.

The native grasses of blue gramma, buffalo, and western wheat grass are the dominant crop consumed during grazing activities.

This exhibit provides all information necessary to calculate the costs of reclamation broken down into the various major phases of reclamation (Sub -section 6.4.12(1) of the Rules and Regulations). The information is sufficient to calculate the cost of reclamation that would be incurred by the state under a forfeiture situation. All Cells have varying area sizes that will be mined in different phases. Each Cell area is used to calculate the maximum reclamation liability. • Cell 1 - will be mined and reclaimed. This phase would be reclaimed as mining progresses in 5 -acre increments at the final reclamation slope of 3 horizontal to 1 vertical (3H: 1V). Cell 1 will require final grading, topsoil placement as necessary around the pond and reseeding in addition to the wetland mitigation at the NW and SE corners • Cell 3 to be mined and reclaimed. This phase would be reclaimed in 5 -acre increments at the final reclamation slope of 3 horizontal to 1 vertical (3H: 1V). Cell 3 will require final grading, topsoil placement as necessary around the pond and reseeding in addition to the wetland mitigation at the NE corner • Cell 2 would be mined and reclaimed. This phase would be reclaimed at the final reclamation slope of 3 horizontal to 1 vertical (3H: 1V). Cell 2 will require final grading, topsoil placement as necessary around the pond and reseeding in addition to wetland mitigation at the SE corner • After all mining is completed, the service roads and the bridge will remain Exhibit F-1 summarizes the reclamation plan for the first 5 -acre phase Celli. For bonding purposes, the only difference during a default scenario where DRMS would complete reclamation is that the slope on the west side of the cell would not be at reclamation slopes. Thus, to quantify the materials for a bonding scenario, we made the following reclamation assumptions: • All mined slopes are at reclamation slopes • Topsoil needs hauled and placed on the bank above the water table • The west side of the cell above the water table requires slope from 2H:1 V to 3H:1V Loveland Ready -Mix, Concrete, Inc. 37 30310913_master_application_Inn_drompit_final draft.docx September 2021 TELEST° • The wetlands are backfilled but need seeding • The outlet weir is in place • The access road from the bridge to the pit needs ripping and seeding Figure 4 summarizes these reclamation assumptions. Table 8 summarizes the reclamation quantities for the default scenario. DRMS prefers to complete the cost estimate themselves after receiving the estimated reclamation quantities. Our internal estimate is less than $5,000 to complete reclamation under this default scenario.

(LRM) has filed an application for a Gravel Pit Well Permit and a Substitute Water Supply Plan for a proposed gravel pit. The proposed operation is known as the Dunn Pit, and is located at or near Section 3, Township 4 North, Range 67 West, 6th Prime Meridian. The proposed date of commencement is January 2023, and the proposed date of completion is September 2045. The proposed future use of the land is wildlife habitat. The Colorado State Engineer's Office regulations require that LRM request a waiver from owners of wells within 600 feet of the proposed pit. Our records show that your well (Permit number 300650) is within 600 feet of the proposed Dunn Pit. As part of the Gravel Pit Well Permit and Substitute Water Supply Plan, a waiver of objection is being requested. If you choose not to sign the waiver, a hearing will be held before the State Engineer at which point you will be asked to submit evidence of injury to your well due to LRM's gravel pit operations. Telesto Solutions, Inc. has designed and calibrated a detailed groundwater model that predicts the effects of all phases of mining on surrounding groundwater and your well. We would be happy to review the results of this model and discuss how it will affect you. Please review the attached application that was submitted to the State Engineer on behalf of LRM. Once you have reviewed the application, sign the attached waiver and return it in the enclosed stamped and self-addressed envelope or contact us if you have any questions regarding this form or impacts to your well. If you have any questions or concerns, or would like additional information, please feel free to contact me at 970-484-7704 or ttigges@tlesto-inc.com.

(LRM) has filed an application for a Gravel Pit Well Permit and a Substitute Water Supply Plan for a proposed gravel pit. The proposed operation is known as the Dunn Pit, and is located at or near Section 3, Township 4 North, Range 67 West, 6th Prime Meridian. The proposed date of commencement is January 2023, and the proposed date of completion is September 2045. The proposed future use of the land is wildlife habitat. The Colorado State Engineer's Office regulations require that LRM request a waiver from owners of wells within 600 feet of the proposed pit. Our records show that your well(s) (Permit numbers 226967A and 226967B) are within 600 feet of the proposed Dunn Pit. As part of the Gravel Pit Well Permit and Substitute Water Supply Plan, a waiver of objection is being requested. If you choose not to sign the waiver, a hearing will be held before the State Engineer at which point you will be asked to submit evidence of injury to your well due to LRM's gravel pit operations. Telesto Solutions, Inc. has designed and calibrated a detailed groundwater model that predicts the effects of all phases of mining on surrounding groundwater and your well. We would be happy to review the results of this model and discuss how it will affect you. Please review the attached application that was submitted to the State Engineer on behalf of LRM. Once you have reviewed the application, sign the attached waiver and return it in the enclosed stamped and self-addressed envelope or contact us if you have any questions regarding this form or impacts to your well. If you have any questions or concerns, or would like additional information, please feel free to contact me at 970-484-7704 or ttigges@telesto-inc.com.

Given that LRM plans to mine the pits sub-aqueously, the water table lowers the strength of the underlying soils. The analysis shows that LRM can excavate the pits wet using a large excavator, but that the excavator will require a working platform roughly 16'x20' to distribute the excavator load. The platform can consist of 8"x8" treated timbers (i.e., railroad ties) or similar. A cable interwoven through the timbers will make movement easier for skidding or moving with the excavator. We can help you design this as mining approaches. The stability analysis also evaluated key structures within 200 feet of the proposed pits and found that the pits remain stable with no undue influences on the structure stability. If you have any questions regarding this analysis, please do not hesitate to contact me at your earliest convenience. Sincerely, Telesto Solutions, Inc. /7/ )/()thA leie( Walter L.

(LRM) plans to mine their Dunn Pit, located outside of Milliken, Colorado, once permits are obtained. LRM plans to mine the pit wet (i.e., sub-aqueously), utilizing an excavator from the bank. In order to size the excavator, LRM needs to know the safe, working slope angle of the banks and pit embankment. Additionally, the Colorado Department of Reclamation and Mine Safety (DRMS) requires in Rule 6.5 (2) that: "On a site -specific basis, an Applicant shall be required to provide engineering stability analyses for proposed final reclaimed slopes, highwalls, waste piles and embankments. An Applicant may also be required to provide engineering stability analyses for certain slopes configuration as they will occur during operations, including, but not limited to embankments. Information for slope stability analyses may include, but would not be limited to, slope angles and configurations, compaction and density, physical characteristics of earthen materials, pore pressure information, slope height, post -placement use of site, and information on structures or facilities that could be adversely affected by slope failure." Objectives: 1. Determine the safe working pit embankment slopes for LRM's mining plan and that it meets Rule 6.5(2) 2. Provide information for LRM's DRMS permit application to satisfy Rule 6.5 (2) for surrounding infrastructure Approach: 1. Based on exploration drilling and recent groundwater level monitoring and modeling efforts, develop conceptual working cross -sections of pit embankment excavation 2. Utilize results of particle -size distributions and boring logs to define a conservatively based data set for the alluvium's geotechnical properties 3.

This calculation set shows that mining slopes of 2H:1V meet the FOS requirement of 1.5 for assumed strength values (effective stress, (I)). The assumed of 37° is for poorly graded sand, when the bulk of the material is well graded sands and gravels where is > 38° and more like 40° 2. A platform is needed during mining to distribute the excavator load when digging. A higher angle may change this result as more data become available 3. The pits do not affect the closest critical infrastructure (railroad, oil and gas tank, county road and home) as the model shows that failure surfaces do not intersect the pit, and FOS are all > 1.6 Conclusions The calculation set met its objectives 1. It determine that a 2H:1V working pit embankment slope for LRM's mining plan meets DRMS's stability FOS of 1.5 2. It provides information for LRM's DRMS permit application to satisfy Rule 6.5 (2) and showed that structures within 200' of the planned mine perimeter are not influenced by the pits References: ;Et r. r'i't[JY.'.

We modeled various floods flows utilizing an unsteady, 2 -dimensional flow model and identified the areas where flood waters would first enter the cells, then modeled the maximum flows expected during a 100 - year peak event to determine the size of riprap protection required.

(LRM) plans to mine their Dunn Pit, located outside of Milliken, Colorado, once permits are obtained. The planned mine pits all reside within the Big Thompson River 100 -year floodplain. The Colorado Department of Reclamation and Mine Safety (DRMS) requires, and good practice dictates, that mine pits within the floodplain be able to safely pass floodwater through the pits with no significant damage. Objectives: 1. Determine if and where protective measures are needed to safely convey floodwater through the planned mine pits 2. Design inlet/outlet structure hard armor if protective measures are needed Approach: 1. Develop a 2 -dimensional HEC-RAS model to predict shear stresses at the pit inlets and outlets during river flow rates of up to and including the 100 -year flood 2. Determine peak shear stresses for vegetated slopes and riprap armoring to be utilized in the inlet/outlet protection scheme 3. Identify areas requiring protection 4. Specify vegetative or riprap D50 for areas requiring protection Data and Assumptions: 1. 100 -year flood flows (8,917 cfs; derived from "BIGLOVCO" CDWR gauging station record), considering lower flows as cells overtop prior to full inundation 2. Geometry -2015 and 2018 digital elevation models based on LiDAR surveys (CHAMP). Pit designs based on current mine designs 3.

Flow enters Cell 1 on the SW corner roughly during a 4 -year peak event (^'1,000 cfs). This establishes a good location for controlled entry into Cell 1 2. Flood waters enter Cell 2 on the northern end at around a 10 -year peak event (^'3,000 cfs), establishing a good control location for controlled entry into Cell 2 3. Flow enters Cell 3 on the northeastern corner at around a 70 -year peak event (^'8,000 cfs), establishing a good control location for controlled entry into Cell 3 4. At planned inlets, typical riprap sizes range from 12 to 24 inches with the SW and NW corners of Cell 1 protection being specified as grouted 24 -inch riprap 5. By the time water starts to exit the pits, the entire floodplain is inundated, and flow is spread across the valley, reducing velocities and shear stresses, :. no outlet protection is needed (i.e., water does not enter and then exit the cells providing a clear exit location) Conclusion: 1. The calculation met its objective and determined that protective measures are needed where primary flow enters the planned mine cells 2.

LRM is developing formal mining plans for the Dunn Pit to extract aggregate resources for the sole use in its concrete-batching operations. LRM plans to: • Mine the aggregate materials "wet" (i.e., no dewatering) • Stockpile mined material adjacent to the active mining area • Load drained materials into trucks and haul aggregate material to LRM's Johnstown Concrete -Batch plant located at the corner of Weld County Road (WCR) 54 and WCR 13 • LRM will process (i.e.., screen, segregate, and crush) the aggregate materials at their Johnstown Site for use in their mixing of concrete for sale in Northern Colorado. The Johnstown Site is a fully permitted, industrial zoned operation • LRM plans to mine 200,000 tons of aggregate per year LRM is completing the mining permitting with Colorado Division Reclamation, Safety and Mining (DRMS) staff, and moving towards a use by special review (USR) permit with Weld County Staff. Thus, LRM anticipates having permits and infrastructure in place to start mining sometime in 2023. Therefore, the period upon which we base this request for a Substitute Water Supply Plan (SWSP) begins in January of 2023 and extending through December 2023. 1.2 Objectives The purpose of this document is to: 1. Document the consumptive use of groundwater estimating process 2. Predict the net depletions to the Big Thompson River (River) 3. Describe the SWSP to offset the River's net depletions Loveland Ready -Mix Concrete, Inc. 1 20210830_dunn_swsp_vcrl Aurust 2021 TELESTO 1.3 Water Usage and Consumption LRM will begin its Dunn Pit by excavating Phase 1 of the Dunn Site, segregating topsoil and stockpiling materials for transportation to the Johnstown site. Consumptive use from the operations will include: 1. Pit evaporation 2. Dust suppression 3. Aggregate entrainment 4. Reclamation vegetation establishment 1.4 Plan for Replacing Out -of -Priority Depletions Alluvial groundwater is the planned water supply for the Dunn Pit Operations. Consumptively used groundwater will cause lagged depletions to the Big Thompson River (River). The City of Loveland (City) agreed to replace the depletions as documented in the attached agreement (Appendix A). City will supply the water directly to the Big Thompson River from the City's wastewater treatment facilities. 2.0 SITE WATER BALANCE LRM will use "wet mining" techniques and no ground water pumping is required. Water from the mined gravel will drain and return to the groundwater via the pit. 2.1 Dewatering No dewatering is anticipated in the mining operation because of the wet mining technique being used. 2.2 Consumptive Use Following the Colorado Department of Water Resources' (CDWR's) "General Guidelines for Substitute Water Supply Plans for Sand and Gravel Pits" (CDWR, 2011), we estimate gross evaporation rates from the pit area using the NOAA Technical Report NWS 33, the maximum evaporation area from the mine plan, and the monthly distributions as described Loveland Ready -Mix Concrete, Inc. 2 20210830_dunn_swsp_vcr1 Aurust 2021 TELESTO in the guidelines. The CDWR guidelines allow credit of historically consumed precipitation as calculated over the open water body associated with gravel production. We also estimate evaporative losses from: • Aggregate entrainment • Dust suppression We estimate the evaporative losses from these ancillary facilities by using NOAA Technical Report NWS 33, the monthly distributions (CDWR, 2011), and estimated evaporative areas. LRM's is assuming the same annual amount of dust suppression water as their Johnstown Plant or 1.41 acre-feet per year. Together, the estimated evaporative losses make up the anticipated depletions from LRM's Dunn Pit. Table 1 describes calculations quantifying the depletions and provides a total for each month. In summary for the first year of operations: • Net evaporation predicted is 42.50 acre-feet • Water utilized for dust control is 1.41 acre-feet, based on LRM's Johnstown usage per acre and assuming 1 acre of haul roads and working area • The estimated aggregate production rate of 200,000 tons per year and a water table elevation of 4737.5 ft results in a depletion of 3.99 acre-feet based on 4% (by weight) water retained in the mined product below the water table • The estimated requirement for vegetation establishment is 2.5 acre-feet • The total estimated depletions are 21.80 acre-feet The future mining at LRM's Dunn Pit is a prediction only. LRM requests that monthly mining numbers may exceed the monthly estimates, so long as LRM does not exceed the total amount of depletions, and they replace the actual monthly lagged depletion (Section 3). Actual monthly mining numbers will be reported using the accounting form shown in Table 4. 3.0 LAGGED DEPLETIONS Telesto utilized the Glover solution as programmed into the Alluvial Water Accounting System [AWAS, (IDS, 2016)] to develop a monthly unit discharge function (UDF) for Loveland Ready -Mix Concrete, Inc. 3 20210830_dunn_swsp_vcr1 Aurust 2021 TELESTO evaporation. We used Geographical Information System (GIS) data downloaded from the South Platte Colorado Decision Support System to set the boundary conditions for the Glover solution. We chose the alluvial aquifer boundary option as the closest representation to the physical setting of the site due to the thinning of the alluvium to the north and south of the river. Input to AWAS included: • Transmissivity-14,939 gal/day/ft • Storage Coefficient -0.20 • Distance to River from the Phase 1 boundary -150 feet • Distance to the parallel no -flow boundary from the Phase I pumping center —760 feet Table 2 displays the resulting UDF. Table 3 documents the use of the UDF to estimate the total lagged depletions to the River. 4.0 REPLACEMENT SOURCES As described in the introduction, the City will supply replacement water via wastewater treatment plant. The water from the treatment plant is adjudicated for augmentation purposes. We understand that Colorado Department of Water Resources requires an additional 1.8% of release per river mile to cover carriage losses in this section of the river. 5.0 OPERATION PLAN The central point of the water management for LRM's Dunn Pit is the wet mining technique. Thus, LRM plans to restrict the active mining operation to five acres. When a five -acre pit is completed, LRM will reclaim the site while continuing to the next five acre parcel. LRM will calculate the monthly net depletion or accretion to the site ponds and apply the lagging equations reported in the previous section to track the required replacement to the River in the subsequent months. LRM will keep a running total of the required replacement and the actual replacement source and quantity. Table 4 is a draft form that LRM proposes to use for calculating and tracking site depletions. They will update Table 3 as they collect actual data to calculate the lagged depletions and required River replacements. Loveland Ready -Mix Concrete, Inc. 4 20210830_dunn_swsp_vcrl Aurust 2021 TELESTO 6.0 OPINION OF NON -INJURY We have developed this plan to account for and replace depletions to the River that could be caused by LRM's future Dunn Pit. LRM will operate this SWSP through an agreement with the City to deliver wet water near or upstream of the point of depletion on the River above any senior water right ensuring no injury to those rights.

WHEREAS, the City owns certain water which, pursuant to the water laws of the state of Colorado, may be used, re -used and successively used to extinction (the "Fully Consumable Water"); and WHEREAS, the Lessee wishes to lease from the City the right to use a portion of the City's Fully Consumable Water; and • WHEREAS, the City is willing to lease to Lessee a portion of its Fully Consumable Water pursuant to certain terms and conditions as set forth in this Lease, NOW, THEREFORE, in consideration of the mutual promises and covenants contained herein and other good and valuable consideration, the receipt of which is hereby acknowledged, the parties agree as follows: 1. The City hereby leases to the Lessee the right to receive two hundred acre feet of the City's Fully Consumable Water, as defined in paragraph 4 of this Lease, on an annual basis. This Lease shall be for a term of twenty-five (25) years, ending on riz.c.3i1W7.2, However, Lessee shall have the option to renew this Lease for successive terms of twenty-five years, which option shall terminate only if Lessee is in default of its payment obligations under paragraphs 6 or 7 of this Lease or if Lessee elects not to exercise its option to renew by giving notice to the City pursuant to paragraph 13 of this Lease not. later than three (3) months prior to the end of any twenty-five (25) year term. In the event Lessee is not in default of its payment obligations and elects to renew the Lease for any successive twenty-five year period, Lessee shall not be required to pay any additional amounts under this Lease for the right to receive its allotted amount of the City's Fully Consumable Water as set forth above. 2. The two hundred acre feet of Fully Consumable Water which the Lessee shall be entitled to receive annually is hereinafter referred to as the "Leased Water." The parties recognize that, simultaneously with the execution of this Lease, the City has leased the right to receive one hundred acre feet of its Fully Consumable Water to Coulson Excavating Company and that the City may, in the future, lease additional portions of its Fully Consumable Water to persons other than Lessee. The Lessee's right to receive two hundred acre feet of the City's Fully Consumable Water pursuant to this Lease shall be equal to the right of Coulson Excavating Company to receive its one hundred acre feet of Fully Consumable Water such that in the event less than three hundred acre feet of Fully Consumable Water is available in any year, Lessee and Coulson Excavating Company shall each be entitled to receive a proportionate share of the available Fully Consumable Water. The right of Lessee to receive two hundred acre feet of the City's Fully Consumable Water under this Lease shall be deemed to be a first right relative to all others, such that in the event the available Fully Consumable Water in any year is in excess of three hundred acre feet but is not sufficient to meet the needs of all persons holding leases of Fully Consumable Water, Lessee shall receive up to its entire two hundred acre feet allotment from the first three hundred acre feet of Fully Consumable Water available. 3. In consideration of the right to receive the Leased Water, Lessee shall, upon execution of this Lease, pay City the sum of Four Hundred Forty Thousand and 00/100 ($ 440,000.00) Dollars in certified funds. By entering into this Lease with the Lessee, the City is and shall be under no obligation to file an application for a change of water rights or for a plan of augmentation concerning the use of the Leased Water by the Lessee. The City shall not be responsible for the implementation of any temporary substitute supply plan or augmentation plan concerning the use of the Leased Water. The cost and expense of any such proceeding shall be that of the Lessee. The City agrees to furnish sufficient Leased Water so that, subject to the provisions of this Agreement, the net usable first use or subsequent use water obtained by the Lessee shall be 200 acre feet. The City shall not be obligated to deliver Leased Water to Lessee unless Lessee shall have first provided written notice to the City that Leased Water will be required in a given year by April 1 of the preceding year. The City shall deliver the Leased Water under this Lease in a total annual quantity as specified by the Lessee and at specific monthly delivery times and in specific monthly quantities according to the evaporation table, attached hereto as Exhibit A, or as otherwise agreed by the City and the Lessee in writing. In no event shall the monthly deliveries exceed the monthly amounts shown on Exhibit A unless hereafter agreed in writing by the City and the Lessee. The Lessee shall not have the right to carryover from month to month or from year to year any Leased Water which was deliverable, but not requested for delivery, in a prior time period. If the maximum allowable delivery under this Lease is not requested by Lessee in any month, the right of Lessee to call for the delivery of such water shall lapse and all such water shall remain the sole property of the City. 4. In'supplying the Leased Water pursuant to this Lease, the City may use any water, including, but not limited to the following sources of water which may be used to extinction (the "Fully Consumable Water"): a. Native water from the Big Thompson River basin which, when stored within the City's reservoir system, may be totally consumed pursuant to the terms and conditions of the Decree for Change of Water Rights for the City of Loveland, dated June 18, 1985, Case No. 82-CW-202A, Water Court Division One, State of Colorado or subsequent actions; and b. Water under an Allotment Contract with the Municipal Sub -District of the Northern Colorado Water Conservancy District (the "Northern District"), commonly known as Windy Gap Water; and c. Any water subsequently acquired by the City and determined by Water Court Decree to be totally consumable. 5. The City shall have the right to deliver the Leased Water to Lessee from any of the sources of Fully Consumable Water, at the City's sole discretion, and shall have the right to determine if any or all of the Leased Water shall be first use water or subsequent use water. The City shall never be required to deliver first use water, even if it is the only Fully Consumable Water available to meet the terms of this Lease. In the event the only water available to the City to meet the terms of this Lease is first use Windy Gap Water and the City is willing to deliver such first use water, the City shall notify the Lessee prior to delivering such water and the Lessee shall have the option to accept the first use Windy Gap Water and pay the costs of delivering such water pursuant to the terms of paragraph 6 of this Lease. In the event the Lessee refuses to accept the delivery of the first use Windy Gap Water, the City shall be deemed to have met its obligations under this Lease, until such time as a source of Fully Consumable Water, other than first use Windy Gap Water, becomes available. In the event the City is reasonably able to but fails to exercise its rights under Case No. 82CW202A sufficient to meet the demands under this Agreement, (unless the exercise of such rights would impair the City's ability to meet the normal domestic needs of the City), and the only water available to the City to meet the terms of this Lease is first use Windy Gap Water, the Lessee shall not be required to pay the delivery charges provided in paragraphs 5 or 6 for the delivery of such first use Windy Gap Water. 6. In the event the Lessee agrees to accept the delivery of first use water from the City's allotment of Windy Gap Water, Lessee shall pay to the City, the, total costs of all pumping and conveyance charges, plus any assessments and fees for administrative, operating, maintenance and any other fees or costs charged by the Sub -District for delivery of the water to the City. The Lessee shall pay the City the total estimated costs in advance, and the City shall not be obligated to deliver any such water until it has received the full estimated payment. In the event the estimated costs paid by the Lessee are less than the actual costs incurred by the City in delivery of Windy Gap Water to the Lessee, Lessee shall pay the City any additional amounts owed within thirty days of receipt of an invoice from the City setting forth the amount owed. In the event the Lessee shall fail to pay such additional amounts upon receipt of an invoice from the City, the City shall have the right, in addition to any other legal or equitable remedies it may have, to refuse to deliver any Leased Water until such time as all additional amounts owed pursuant to this paragraph have been paid in full. In the event the estimated costs paid by the Lessee are greater than the actual costs incurred by the City in delivery of Windy Gap Water to the Lessee, the City shall refund any excess within thirty days of the City's receipt of an invoice from the Northern District. 7. Lessee shall pay the City's reasonable costs incurred in administering the terms of this Lease. For the first five years of this Lease, the administrative costs shall be One Thousand and 00/100 Dollars($1,000.00) per year, payable in advance. The City shall recalculate the reasonable administrative costs every five years and inform the Lessee in writing of the change at least thirty days prior to the start of the new five year period. In the event the Lessee does not require the delivery of any of the Leased Water in a given year,. there shall be no administrative costs charged. The City shall invoice the Lessee for the annual administrative costs in January of each year and Lessee shall pay said costs within thirty days of the invoice date. In the event the Lessee shall fail to pay its accrued administrative costs in any year, the City shall have the right, in addition to any other legal or equitable remedies it may have, to refuse to deliver the Leased Water until such time as all accrued administrative fees have been paid in full. B. At the option of the City, delivery of the Leased Water shall be made at the City's Waste Water Treatment Plant, 700 South Boise Avenue, Loveland, CO, or at such other downstream location or locations above the Lessee's original point of need as agreed by and between the Lessee and City in writing. Lessee shall not unreasonably withhold its approval of any request by the City to move the point of delivery. 9. Subject to the provisions of paragraph 5, the City shall only be obligated to deliver the Leased Water to the Lessee if water meeting the requirements of this Lease is reasonably available to the City. In the event of a drought or other conditions, restrictions or emergency situations beyond the control of the City which limit the City's ability to receive or deliver all or a portion of the Leased Water to the Lessee, the • City shall be relieved of its obligations to deliver such water under the terms of this Lease until such time,as conditions' permit the City's receipt and delivery of the Leased Water. 10. The Lessee shall take the Leased Water AS IS and the City makes no express or implied warranties of any kind or nature, including the warranties of merchantability or fitness for a particular purpose, concerning the water quality of the Leased Water. 11. In the event the Lessee wishes to assign, encumber or exchange its rights to receive all or any portion of the Leased Water not already used to satisfy a temporary substitute supply plan or permanent augmentation decree to a third party, the City shall have the first right of refusal to reacquire said rights. In such event, Lessee shall notify the City in writing and shall provide the City with a copy of the signed agreement between the Lessee and the third party. The City shall have the right to reacquire the water rights within ninety days from receipt of the notice, by informing Lessee of its intent to exercise its first right of refusal and by paying Lessee the contract price as set forth in the agreement between the Lessee and the third party. If the City does not exercise its right of first refusal, the Lessee may assign or transfer its rights to a third party, and the third party shall be bound by all terms and conditions of this Lease, including the obligation to allow the City the first right of refusal on any transfer or assignment of the Leased Water, it being the intent of this Lease that the City's right of first refusal shall apply to each and every transfer of the Leased Water which may arise at any time during the existence of this or any subsequent Lease. The right of first refusal set forth in this paragraph shall not apply in the event the Lessee wishes to assign, encumber or exchange its rights to receive all or any portion of the Leased Water to a third party pursuant to an exchange which is a transfer, sale or assignment of all or substantially all of Lessee's assets to said third party. 12. After the City has increased the storage capacity of Green Ridge Glade Reservoir to at least five thousand (5,000) acre feet, and upon sufficient advance written notice so as to permit the City to place appropriate orders for replacement water, the Lessee may temporarily sub -lease the Leased Water or portions thereof to third parties without activating the City's right of first refusal as set forth in paragraph 11, so long as the length of the sub -lease term and the amounts and times of discharge required by the Sub -lessee are acceptable to the City. Any such lease arrangement shall first_be provided to the City for its review and approval, which approval shall not be unreasonably withheld. 13. All notices shall be in writing and shall be deemed given if personally delivered or mailed, certified mail, return receipt requested, to the following addresses: If,to City, to: City of Loveland Water & Power Department Attn: Ralph Mullinix, Director 200 North Wilson Avenue Loveland, Colorado 80537 with a copy to: City of Loveland Attn: City Attorney 500 East Third Street Loveland, Colorado 80537 If to Lessee, to: Loveland Ready Mix 1811 West 12th Street Loveland, Colorado 80537. 14. No alteration or other modification of this Lease shall be effective unless such modification shall be in writing and signed by the parties. 15. In the event any portion of this Lease should become invalid, the remainder of the Lease shall remain in full force and effect. 16. This Lease shall be governed by and construed in accordance with the laws of the State of Colorado. This Lease shall inure to the benefit of, and be binding upon, the successors in interest of the respective parties.

(Telesto) conducted a baseline groundwater assessment to: • Support geotechnical analyses associated with bank stability during sub- aqueous mining and closure • Support wetland mitigation designs • Assess potential impacts associated with the proposed Loveland Read - Mix's Dunn Pit (Pit) sand and gravel mine. The proposed sand and gravel mine has the potential to modify groundwater flow patterns and affect surrounding groundwater levels. Telesto developed a groundwater conceptual site model (CSM) to quantify and summarize the available data and mechanics of the existing groundwater system. The CSM formed the basis of a numerical representation (i.e., numerical model), which Telesto calibrated using measured groundwater level data and area features such as levels of the Big Thompson River and surrounding irrigation ditches. The calibrated numerical model then simulated mining impacts to surrounding groundwater levels, flows through wetlands and the piezometric surface used in geotechnical stability analyses. The numerical model simulates that the unlined mine cells will "flatten" gradients immediately adjacent to the pits, and have a drawdown upgradient and a small mounding downgradient. No significant injury to any registered well owner is anticipated. The Dunn domestic well will incur the largest drawdown (predicted at 3.8 feet, slightly over 10% of its completed depth). However, resulting gravel pit lakes will serve to enhance the wells' production efficiency.

(Telesto) conducted a groundwater study to assess potential impacts associated with the proposed Loveland Read -Mix's Dunn Pit, a proposed aggregate mine. Although LRM will mine the resource sub-aqueously and will not dewater pits, there is a potential to change the groundwater flow regime. To gain a thorough understanding of potential outcomes of the proposed mining project, Telesto developed conceptual models to summarize the available data, and hydraulics of the Big Thompson alluvial groundwater system. From the conceptual model, Telesto formulated a numerical representation (i.e., numerical model) which they calibrated to local groundwater level data. They utilized the numerical model to predict potential impacts on the groundwater system. The groundwater model formed a basis for assessing the needs for mitigation plans and management techniques to protect neighboring groundwater resources. 1.1 Project Description LRM proposes a new aggregate mine adjacent to Weld County Road (WCR) 481/2, immediately west of Colorado Highway 257 near Milliken, Colorado. LRM seeks approval for the Project through the Colorado Natural Resources Department, Division of Reclamation, Mining, and Safety (DRMS), and Weld County's Use by Special Review process. LRM currently leases the site for cattle pasture as it has since purchasing the property in the early 1980s. LRM owns approximately 114 acres of which approximately 75 acres encompasses the proposed mining area. LRM will reclaim mined slopes above the water table soon after mining pit areas and will establish new wetland areas in select portions of the pits. The proposed Dunn Pit straddles the Big Thompson River (River), which is responsible for the deposition of the alluvial materials sourcing aggregate. Current and historical aggregate mining is prevalent along the River as seen in Figure 1. The site is relatively flat with topography generally mimicking the Big Thompson River. As seen in Figure 2, surrounding properties include to the: LRM 2o210910w_reportdoox September 2021 TELESTO • North A railroad right of way Golf course community • East • South • West Highway 257 right-of-way Agricultural properties and home Weld County Road 48 '/z right-of-way Six homes and outbuildings on agricultural properties Home and outbuildings on agricultural property Large agricultural fields Big Thompson River floodplain Also shown in Figure 2 are key features affecting groundwater flow in the area including: • The Big Thompson River • Hill and Brush Ditch • Big T and Platte Ditch • Historical aggregate pit lakes • Permitted and suspected water wells 1.2 Objectives The objectives of this report are to: • Describe the groundwater system associated with the Project • Predict potential impacts to groundwater and its users, including: Changes in groundwater elevations that would affect residents or well users Changes in flow paths for potential migration of impacted water • Provide mitigation strategies should impacts (predicted or realized) be unacceptable 1.3 Approach This report consolidates available information on climate, geology, surface water, and groundwater to develop a conceptual hydrogeologic model for the proposed Project and adjacent area. A two-dimensional numerical groundwater flow model quantifies the conceptual model incorporating relevant aspects of the hydrologic system. To improve its LRM 2O21O9io_gw_reportdoox 2 September 2021 TELESTO predictive capabilities, the numerical model is calibrated to known hydraulic heads measured in on -site monitoring wells. The focus of this effort is to provide a defensible technical basis for predicting groundwater -related impacts associated with commencement of mining, on -going operation, and future closure of the Pit, and to provide an evaluation tool for developing mitigation strategies if required. 2.0 BACKGROUND Aggregate mining is currently and historically prevalent along the Big Thompson River corridor. As entities extracted and processed the alluvial deposits into construction materials, the sites were reclaimed for residential, agricultural, wildlife habitat, or water storage uses. In the reclamation processes, groundwater conditions reverted to conditions similar to the pre -mining status. Figure 1 shows the locations of local aggregate mines that beneficiated Big Thompson River alluvium; the Colorado Department of Natural Resources, Division of Reclamation, Mining, and Safety (DRMS) maintains a map of aggregate mines (i.e., construction material sites) (CDRMS, 2021). Following cessation of mining, many pits were reclaimed as lakes, or reverted to open space used for grazing or wildlife habitat. 2.1 Geologic Setting The Project lies in the Colorado Piedmont physiographic province (Palkovic, et al., 2018), at the northwester margin of the Denver sub -basin within the Denver-Julesburg basin, with the Northern Rocky Mountain Front Range uplift to the west (Kirkham & Ladwig, 1980). The Project terrain is characterized by the Big Thompson River floodplain, and heavily influenced by the Little Thompson and South Platte River confluences to the east. To the north, outcrop of the transitional Pierre Shale formation underlies the sandstones of the Fox -Hills formation, exposed in the bluffs bordering the Big Thompson River. Both are topped by eolian deposits of the upper Holocene and Pleistocene. On -site alluvial deposits consist of Holocene and upper Holocene deposits as shown in Figure 3. Terrace gravel deposits are prevalent on the upper topography to the south of the Big T and Platte Ditch. LRM 2O21O9io_gw_reportdoox 3 September 2021 TELESTO The Project overlies unconsolidated alluvial deposits of Quaternary age deposited during natural meandering of the ancestral Big Thompson River system. The alluvial sands and gravel were eroded from the Rocky Mountains to the west and deposited along broad areas of the river valley. Alluvial deposits underlying the Project care poorly sorted (well graded) granite -sourced clays, silts, sands, and gravel with very few cobbles. The Big Thompson alluvial deposits lie on an erosional contact with the transitional member of the Cretaceous Pierre Shale. The Pierre Shale is relatively impermeable and considered a bedrock aquiclude when evaluating alluvial -bedrock groundwater interactions. 2.2 Hydrologic Setting 2.2.1 Climate The Site is in a semi -arid region of the northern Front Range area of Colorado. The regional climate is summarized by data obtained from the Western Regional Climate Center web site (WRCC, 2017). 2.2.2 Surface Water Regional Drainage The Site is located within the 835 square -mile Big Thompson river basin, a tributary to the South Platte River that generally drains to the east. Within Weld County, the River drains a total area of approximately 86 square miles. Perennial flow exists in the River from the mouth of the Big Thompson canyon downstream through Loveland on through the town of Milliken. In the spring and early summer, the Big Thompson recharges an extensive valley -fill alluvial aquifer. Infiltration from irrigation diversions and roadside swales adds to the alluvial aquifer recharge from mid -summer through early fall. Dry season river flows are minimal and consist primarily of municipal wastewater plant discharges, and irrigation sourced groundwater return flows from the extensive valley -fill alluvial aquifer. LRM 2O21O9io_gw_reportdoox 4 September 2021 TELESTO Local Drainage Site ground surface elevations range from 4,754 feet in the northwest corner of the property to 4,735 feet near the railroad bridge over the Big Thompson river. It lies entirely in the 100 -year Big Thompson river regulatory floodplain as defined by FEMA. Surface runoff from the site and surrounding area occurs as sheet flow off pasture lands or is captured locally in the few small interior wetlands. Offsite storm water runoff is diverted by the railroad to the north and Weld County Road 48 '/2 to the south. The Big Thompson river serves as the main conduit for the removal of stormwater. Once mining operations begin, on -site runoff that historically flowed across the Site will be directed to and retained in the Pits, which will be excavated to 25 -to -30 -foot depths below the current ground surface. Because LRM will mine the pits wet, and plans to leave the pits unlined after mining, captured stormwater will return to the Big Thompson river via groundwater return flows. 2.2.3 Groundwater Regional Groundwater is a source of water for municipal, domestic, agricultural, and industrial uses within Weld County, especially east of Greeley and outside of the South Platte River basin; however, diverted river flows and trans -mountain diversions form the bulk of the water sources for uses in urban areas along the Front Range. The viability of the groundwater resource is dependent on characteristics of the geologic unit from which groundwater is extracted. Well yields (flow rates expressed in gallons per minute) of groundwater wells are controlled by the permeability of the host rocks. • Metamorphic and igneous rocks have relatively small well yields [1 and 15 gallons per minute (gpm)], except in highly weathered granitic rocks that can produce higher yields. Metamorphic and igneous rocks do not provide groundwater in the Project area and will not be penetrated by any proposed mining activities • Marine sedimentary rocks are generally poor aquifers in Weld County. However, fractured carbonate rocks, which most commonly occur near LRM 2O21O9io_gw_reportdoox 5 September 2021 TELESTO major fault structures, can locally provide significant well yields. Marine sedimentary rocks do not provide groundwater in the Project area and will not be penetrated by any proposed mining activities • Wells completed in consolidated and semi -consolidated Tertiary and Cretaceous clastic deposits can yield up to several hundred gpm. These deposits will not be penetrated by any proposed mining activities and do not provide groundwater in the Project area • Unconsolidated stream alluvium along major stream channels range in thickness from 5 to 30 feet thick and can locally provide well yields up to several hundred gpm (Topper, 2003). Properties adjacent to the Site have shallow groundwater wells completed in alluvium. Local Local groundwater flow and levels are strongly influenced by the Big Thompson river, historical aggregate pits that are now unlined lakes or small wetlands. Telesto installed 10 monitoring wells on the site as described in Appendix A. Early summer 2021 depth -to - groundwater measurements are summarized in Figure 4, which depicts the resulting groundwater elevations. LRM plans to monitor these wells monthly for a full year after installation and quarterly thereafter. Also shown in Figure 4 are four permitted wells (CDWR, 2021). The Wagner and Dunn wells are registered as domestic use. The Nelson well is registered for irrigation use. Alluvial groundwater generally follows the flow direction of the Big Thompson river. The Big T and Platte River and the Hill and Brush ditches contribute to groundwater flow during the irrigation season. Neary by historical gravel pits and wetland areas function as evaporative sinks. Water Quality Telesto collected initial samples from the site monitoring wells south of the Big Thompson River on June 8 and 9, 2021. Samples north of the river were thwarted by high flows until August 5, 2021. Laboratory reports are provided in Appendix B. Groundwater is slightly alkaline with a pH ranging between 8.01 to 8.24. The dominant anion is sulfate, while cations are balanced towards calcium and magnesium (Figure 5). Baseline groundwater quality in MW -04 and MW -08 meets Colorado's Water Quality Control Commission (WQCC) Regulation No. 41 standards. The baseline water quality in remaining wells had LRM 2O21O9io_gw_reportdoox 6 September 2021 TELESTO select exceedances of iron, manganese, and uranium (see Appendix B). Iron and manganese are roughly an order of magnitude higher than the standard, while uranium hovers around the standard. This is common along Colorado's Front Range, especially where alluvial aquifers overlie the Pierre Shale formation. Telesto collected samples from select monitoring wells and requested analyses for benzene, toluene, ethylbenzene, xylenes (BTEX) and total petroleum hydrocarbons (TPH). All samples were non -detect with the exception of toluene detected in MW -05, well below the groundwater standard. 2.3 Conceptual Model A conceptual groundwater flow model is a graphical, semi -quantitative description of the parameters and conditions that control groundwater flow. Figure 6 displays the conceptual groundwater flow model associated with the Site as limited to the model boundary shown. Components of the conceptual model are represented in the numerical flow model as various boundary conditions and variables. 2.3.1 Boundary Conditions Model Top The top of the conceptual model is defined by the topography (represented by the most recent LiDAR topography), and a variable flux boundary. The flux represents natural recharge on non -irrigated areas, and excess irrigation that percolates below the rooting zone in irrigated areas. The bounding condition is assumed to be relatively constant throughout the year as irrigation induced percolation will be attenuated on its vertical path to the groundwater table. Likewise, naturally occurring precipitation driven percolation is assumed to be constant throughout the year. Model Bottom The bottom of the conceptual model is the Pierre Shale. As described previously, the Pierre shale acts as an aquitard and is therefore represented as a no -flow (i.e., zero flux) boundary. LRM 2O21O9io_gw_reportdoox 7 September 2021 TELESTO Perimeter The southern perimeter of the model is an assumed flow line and is defined by the contact of the Big Thompson River alluvium and the terrace gravels (Qa3 in Figure 3) to the south, which is represented as a no -flow boundary. The northern boundary is a no -flow boundary defined by the contact with bedrock. The eastern and western boundaries of the model are flux boundaries. To represent this flux, constant head boundaries are used that are related to the stage in the river. Internal Boundaries Within the area of interest, several types of hydrologic boundaries exist related to groundwater flow. Area ditches provide recharge and discharge opportunities for groundwater. Leakage rates can range from 10 to 25% of the flow in the ditch. Un-sealed gravel lakes and active mining pits become discharge points for the alluvial aquifer. Evaporation can be a significant sink in the summer when evaporation rates can reach up to 5.74 inches in the month of July (CDWR, 2011). One irrigation well is known to exist west (and upgradient) of the site. 2.3.2 Hydraulic Parameters Porosity/Storage Coefficient The storage coefficient dictates the amount of groundwater that moves in and out of the pore space as aquifer conditions change (e.g., pumping from a well or cessation of irrigation returns). Storage coefficients for the Big Thompson alluvium range from 15 to 25%. A typical value used in the Milliken area is 20% (CDWR, 2017). Saturated Hydraulic Conductivity The saturated hydraulic conductivity dictates how easily groundwater moves through porous media (i.e., alluvium in this case). Transmissivity is a product of the saturated aquifer thickness and hydraulic conductivity. The CDSS (CDWR, 2017) indicates that the hydraulic conductivity in the Milliken area is around 250 feet/day. LRM 2O21O9io_gw_reportdoox 8 September 2021 TELESTO Telesto performed aquifer pumping test analyses on two of monitoring wells installed at the Dunn site. Saturated hydraulic conductivity from testing ranged from approximately 81 to 95 ft/day (0.028 to 0.034 cm/sec). Appendix C documents the monitoring well aquifer tests. 3.0 NUMERICAL MODEL FRAMEWORK 3.1 Numerical Modeling Code Telesto chose the widely accepted groundwater flow model, MODFLOW 2005 (Harbaugh, 2017). Groundwater flow is mathematically simulated utilizing a block -centered, finite difference approach to solve the corresponding governing differential equations. MODFLOW 2005 is a series of modular subroutines that are highly independent of one another that allows flexibility in simulating a multitude of boundary and geometric conditions. Modeling input was accomplished with a variety of tools including Model Muse (Winston, 2009), Global Mapper 16 (Blue Marble Geographics, 2015) and internal codes developed by Telesto. 3.2 Numerical Modeling Domain The modeling domain is best described as a rectangular grid oriented parallel to the main direction of groundwater flow. It is two-dimensional, variable thickness, unconfined model. In MODFLOW, the modeling coordinates start in the upper left corner and are defined by rows and columns. The upper left corner of the model is located at geographical northing of 40° 21' 59.9324" N and easting of, 104° 53' 58.5849" W. The modeling grid is oriented clockwise around the upper left corner at 105° 31' 59.3" from true north. The model domain is 18,105 feet (3.429 miles) in the x -dimension and 11,500 feet (2.178 miles) in the y -dimension. The model domain is gridded in the x -dimension by 195 columns ranging from 25 to 500 feet in width, and in the y -dimension by 143 rows ranging from 25 to 500 feet. The extents of the model are sufficiently large as to avoid unduly influencing the hydraulics near the Site and areas of concern. Figure 7 displays the model domain oriented against Colorado State Plane North coordinates. LRM 2O21O9io_gw_reportdoox 9 September 2021 TELESTO 3.3 Numerical Model Boundaries Model boundaries define the hydrologic conditions of the aquifer throughout the model domain. As described in Section 2.3.1, various boundary conditions exist. Where bedrock outcrops or sub -crops, the model is inactive or has a zero -flux boundary. Two rivers exist within the model domain: the Big Thompson and the Little Thompson rivers. The two main ditches influencing groundwater near the Site are the Hill and Brush ditch and the Big T and Platte. Rivers and ditches are treated as general head boundaries using the MODFLOW river package. 3.4 Model Parameters Aside from geometry, the main model parameters include: • Hydraulic conductivity — 8 to 250 ft/day • Aerial recharge — estimated at 5 to 10% of precipitation • Lake surface evaporation — (NOAA, 2015) • River Elevation — USGS topography, site survey topography 3.5 Model Timeframe For this effort, Telesto chose to utilize a steady-state model representing the spring -season groundwater levels (highest levels). The steady-state model provides the basis for a series of predictive models that simulate groundwater behavior as the ground water is exposed in the mining cells as mining progress. Each phase of the three cells is modeled as a constant head boundary. 4.0 MODEL CALIBRATION Calibration is the process by which model parameters are adjusted within the range of measured/known values until a set of "targets" is matched. For a groundwater model, targets are drainage discharge rates, increases or losses to surface water features, but most commonly groundwater elevations measured in wells. LRM 2O21O9io_gw_reportdoox 10 September 2021 TELESTO 4.1 Calibration Targets For this modeling effort, the calibration targets are the spring groundwater elevation measurements from the Site monitoring wells. Table 1 lists the information for Site monitoring wells, including the targets (groundwater elevations) used in the model calibration effort Table 1 Monitoring Well Information Well Name Easting' Northing Stickup (ft) Ground Surface Elevation (ft) Depth to Water Measured 5/7/21 (ft) Groundwater Elevation (ft) MW -01 3173581 1368879 3.27 4746.348 9.25 4740.37 MW -02 3173544 1370047 3.32 4748.483 8.52 4743.28 MW -03 3173028 1370961 3.2 4752.183 9.05 4746.33 MW -04 3174494 1369669 3.54 4747.495 9.55 4741.49 MW -05 3174587 1369091 3.74 4742.581 10.21 4736.11 MW -06 3175284 1367834 3.05 4740.507 7.87 4735.69 MW -07 3176101 1367902 2.76 4737.311 6.90 4733.17 MW -08 3175991 1368476 2.83 4739.284 8.30 4733.81 MW -09 3174529 1368109 3.33 4741.733 7.62 4737.44 MW -10 3174626 1369928 3.53 4747.935 11.21 4740.26 4.2 Calibration Results Telesto built the model in a step -wise fashion, adding boundaries (ditches, drains, ponds) one model -run at a time. Once the model was running, we adjusted boundary conditions and hydraulic conductivity within reasonable ranges until the model represented the distribution of measured groundwater elevations in the monitoring and neighborhood wells. Simulated groundwater elevations from the model cells representing wells on the date measurements are compared against measured elevations in Figure 8. Also, shown in Figure 8 are results of regression analyses (coefficient of determination -r2, regression line slope and intercept) and the sum of the difference squared between simulated and measured groundwater elevations indicating the capacity of the model to accurately simulate groundwater levels in the wells. The model simulations of MW -04 and MW -10 are suspect 1 Colorado State Plane Coordinate System - Feet - NAD83(2011NRS) Datum LRM 2O21O9io_gw_reportdoox 11 September 2021 TELESTO as the measured water levels are quite different than simulated. This could be due to the method of surveying ground surface (i.e., general topography instead of point survey at the well location). To evaluate these two wells on model results, we removed their values from the statistics (shown in Figure 8). The model statistics are acceptable without including the MW -04 and MW -10 lending confidence to the model's ability to simulate overall groundwater conditions. Figure 9 is a contour plot of the simulated groundwater elevations representative of the spring season. Comparison of Figures 4 and 9 shows good correlation between model simulated groundwater elevations and flow directions and those measured in the field. 4.3 Parameter/Boundary Sensitivity A sensitivity analysis examines how changing variables within their acceptable range affects the calibration results. Because the model domain contains so many internal boundaries (i.e., Big Thompson River, irrigation ditches, ponds to the south), the model is relatively insensitive to hydraulic parameters. It is very sensitive to the physical construct of the internal boundaries. For example, changing the elevation of the bottom of the ditch near the nearby wells has a direct correlation to the simulated water elevation in the well. Because the physical nature of the internal boundaries are limited by topography, the model sensitivity is less critical. 4.4 Discussion The statistics and plot shown in Figures 8 and 9 indicate that the model successfully mimicked groundwater elevation distributions near the Site for the existing conditions. Visual examination of the scatter around the best fit line, calculated best fit line slope of nearly 1.0, and intercept bordering zero indicates that the model has acceptable bias in the groundwater level predictions and the groundwater flow direction. 5.0 MODEL PREDICTIONS The previous four sections of this report describe the building of the numerical model to provide a base upon which to evaluate potential impacts from LRM's proposed operations. LRM 2O21O9io_gw_reportdoox 12 September 2021 TELESTO The good calibration provides a high level of comfort that the model can accurately identify problematic areas that might produce impacts from the operational scenarios. The overall mine plan related to groundwater is to excavate the pits in a sequential fashion, in roughly 5 -acre increments. LRM will construct an outlet weir on Cell 1 to control the surface water elevation of the resulting lake at elevation 4,737.5 feet. There are no other groundwater controls planned for the cells as LRM will excavate them sub-aqueously (i.e., no dewatering) with no lining. Cells 2 and 3 will connect via an underground pipe to maintain water levels in the completed cells at roughly 4,735 feet elevation. The depths of the four neighboring wells are 32, 45, 56, and 100 feet (shown in Figure 4 as Dunn, Wagner, Wagner 2, and Nelson, respectively). Thus, for the purposes of describing modeling predictions, we considered predicted drawdowns greater than 10% of the well depth as a well needing monitoring for potential impacts. Similarly, we considered a mound (shown as negative value contours on the figures) of two feet or more to indicate areas where a potential may exist for increases in groundwater levels that could pose an issue to homes with basements. The standard deviation of the model residuals is 1.2 feet, thus, the drawdown of 10% of the well depth and two feet mounding are within the model's predictive capacity. 5.1 Mining Plan —Mining Figures 10, through 13 display predicted groundwater elevation and drawdowns at select phases of the mining process. The names of the mining phase match those in Exhibit F of the DRMS mining application. The figures show that subaqueous mining and no lining of the cells tends to flatten the water table near the cell. The maximum drawdown occurs on the upgradient side of the mined cells, with a maximum "mound" at the downgradient end. A predicted drawdown of over 1.2 feet or a predicted mounding of 1.2 feet is considered more than model error. LRM 2O21O9io_gw_reportdoox 13 September 2021 TELESTO 5.2 Mine Plan —Reclamation Figure 15 shows the model -predicted drawdowns after reclamation is complete. Off -site drawdowns near the Dunn well is approaching the 10% monitoring threshold, while mounding is not significant at any off -site location. 5.3 Results Discussion 5.3.1 Drawdown/Mounding Figure 16 summarizes the anticipated changes in groundwater levels associated with neighboring wells. Nelson shows approximately two feet of drawdown well within a range that will not negatively change their ability to withdraw irrigation water from the well. The two Wagner wells will likely experience around a foot of mounding, affecting their wells in a positive manner. The largest potential impact shown is to the Dunn well, where it approaches the 10% of well depth criteria. Drawdown is only one component of a well's ability to extract water. The lakes in Cell 2 and Cell 3 will effectively enhance the production of the well by developing a constant groundwater level nearer to the well. Thus, for the same amount of pumping, the required drawdown in the well will be much less and the well will operate more efficiently. 5.3.2 Water Quality The source of uranium and manganese in groundwater (Appendix B) is likely the underlying Pierre Shale formation. Multiple studies and reports (Sares, 2000; Tourtelot, 1955; Tourtelot, 1962; Carpenter, et al., 1978; Carpenter, et al., 1978) on this phenomena report low levels of both constituents in the sediments, mainly in the form of sulfide (i.e., minerals in reduced forms). They can become even higher concentrations when exposed to the atmosphere and oxygen. One of the large benefits to the sub -aqueous mining proposed for the Dunn Pit is that bedrock will always be under water, reducing even further the chance of exposing the bedrock to oxygen. LRM 2O21O9io_gw_reportdoox 14 September 2021 TELESTO 5.4 Discussion 5.4.1 Model Stability The model converged to a solution during every iteration for the calibration and predictive scenarios, meeting the minimum error criteria in the heads of 0.001 foot. No other significant errors were reported in the model runs. These statistics provide confidence that the model runs were numerically accurate and that the results are numerically sound. 5.4.2 Predictive Results Based on the good correlation and numerical stability of the model, confidence can be placed in the predictive results. The predictions provide a good indicator of areas that will require special attention as mining progresses and gives the opportunity for LRM and neighbors to be pro -active. 6.0 MONITORING PLAN Telesto completed this modeling effort prior to mining. It is calibrated to the spring/early summer timeframe. As time goes by and we collect more data, Telesto will evaluate the model assumptions, and if necessary, update the model for differing conditions. The updated model will provide more accurate predictions and therefore will provide more confidence in the predictive results. The model can be used as a tool to evaluate water supply and other groundwater related issues during operations. The model, however, is only as good as the data on which it is based. Thus, ongoing monitoring of the groundwater is essential. 6.1 Monitoring Plan The mining plan for the Pit assumes a thirty-year mine life. LRM has initiated a pre -mining groundwater monitoring program. The monitoring program consists of monthly depth to ground water measurements of the 10 on -site monitoring wells. Depth monitoring of on - site monitoring wells will shift to quarterly schedule after LRM collects one -years' worth of data are collected and until active operations are completed. LRM 2O21O9io_gw_reportdoox 15 September 2021 TELESTO LRM initiated quarterly water quality sampling from all wells (Appendix B). After LRM obtains one year's worth of quarterly data, we will evaluate the necessity of collecting water quality from all wells on a quarterly basis and propose a modified plan, with justification, to DRMS. 6.1.1 Monitoring Locations To facilitate monitoring groundwater immediately adjacent to the Site, LRM constructed 10 new monitoring wells on the Site properties in May 2021 under State Engineering Office approved monitoring well permits. Monitoring well locations are shown in Figure 4 and well construction permits are included in Appendix A. 6.1.2 Purpose of Monitoring Locations The proposed monitoring locations can be easily accessed by LRM to provide real-time groundwater elevation data. These monitoring locations are intended to provide baseline data representative of pre -mining groundwater levels for the area. Once mining commences, the monitoring locations will capture potential impacts, and provide a base upon which we can review, and update model predicted impacts. 6.1.3 Potential Impacts from Mining Operations As described previously, we do not anticipate large drawdowns or mounding from this project due the sub -aqueous mining approach. We anticipate the largest drawdowns and mounding will occur at the up and down -gradient ends of the pit, respectively. Water quality impacts from exposing the Pierre shale are highly unlikely in LRM's dewatered operations, and improbable under the sub -aqueous mining method. 6.1.4 Water Quality We do not expect mining to impact groundwater quality as previously discussed. However, LRM commits monitoring for metals in groundwater, plus oil sheens in the mined cells. These are the typical sector -specific benchmarks tested in CDPHS discharge permits for sand and gravel pits and batch plants. The water quality monitoring plan is attached as Appendix D. LRM 2O21O9io_gw_reportdoox 16 September 2021 TELESTO 6.1.5 Proposed Trigger Levels and Corrective Actions LRM proposes use of a five-foot drawdown in on -site monitoring wells as a trigger that would initiate more intensive monitoring and discussions of potential mitigation measures with neighbors. If required, LRM will negotiate in good faith to implement corrective actions that are amenable all parties. Corrective actions could include: 1) providing extra augmentation water and supplying water from the mined cells, 2) deepening wells (there is typically an extra 10 feet to bedrock in most domestic wells surveyed) to ensure there is still adequate saturated thickness from which groundwater can be extracted, and 3) re- introducing pumped groundwater through a leach field or injection well back into the aquifer near the impacted well. 7.0 CONCLUSIONS In addition to the objectives summarized in this section, this study describes just a few of the potential mitigation measures available and emphasizes the collaborative strategies that LRM would implement toward neighbors if needed. LRM will work with neighbors to ensure that they have access to and are able to interpret the well monitoring results available on the DRMS website and will continue to collaborate directly with individual landowners as requested. LRM is committed to maintaining communication with neighbors and has taken steps to share the results of this study with adjacent well owners as practical. The modeling efforts met the objectives as outlined in Section 1.2 as follows: • The conceptual model described in detail the groundwater system associated with LRM's Site • The numerical model mimicked existing conditions and then was used to predict impacts. It showed: Changes in groundwater elevations affecting known well users, and provided maps of zones of potential drawdown impacts • Potential mitigation strategies were discussed and evaluated and a plan to monitor and implement corrective actions was provided. As with all models, this model is a numerical representation of the physical system that mimics trends and magnitudes of physical values. While great effort is taken to ensure the LRM 2O21O9io_gw_reportdoox 17 September 2021 TELESTO most accurate representation of the groundwater system, there are still uncertainties resulting from the required assumptions used during the modeling effort. Thus, the model is most useful in identifying areas of potential concern so that management plans can be made to mitigate any potential issues. Again, these areas are where groundwater is predicted to drawdown more than 10% of a neighbors' well depth, or mound higher than 2 feet. 8.0 REFERENCES Blue Marble Geographics, 2015.

The mined material will be Big Thompson River alluvium. LRM retained Telesto Solutions, Inc. (Telesto) to provide oversight for drilling and installing 10 monitoring wells throughout the Site. This drilling summary report presents the drilling, well construction, sampling, and data collection from the 10 monitoring wells installed on Site. The Colorado Division of Reclamation and Mining Safety (DMRS) requires a full year of quarterly groundwater quality and elevation monitoring data prior to the start of mining operations to establish a baseline. The water quality data is analyzed and compared to the Water Quality Control Commission (WQCC) Regulation 41: Basic Standards for Groundwater [i.e., Regulation 41 Standards, (WQCC, 2016)]. Water level data and associated analyses is collected to ensure the hydrologic balance is maintained during and after mining. Thus, Telesto installed the monitoring wells to meet the DRMS requirements. The groundwater monitoring plan (GWMP) consists of installing groundwater monitoring wells, sampling formational materials for potential source identification, and ongoing groundwater quality and level measurements. 1.1 Site Conditions The Site is located within the Northeast 1/4 of Section 3, Township 4 North, Range 67 West of the Sixth Principal Meridian, Weld County, Colorado. The furthermost northwest portion of the site is within the SE 1/4 of Section 34. Township 5 North, Range 67 West of the Sixth Principal Meridian. The site lies south of the Union Pacific Railroad Easement (Figure 1). The topography is generally flat with rolling areas. The surface drainage is parallel with the Big Thompson River in a southeasterly direction. The parcel of land is divided by the Big Thompson River. LRM completed a geotechnical/subsoil investigation on the Site in 1978 (Attachment 1). The purpose of the investigation was to determine the extent and quality of the gravel aggregates found on the Site. Loveland Ready -Mix Concrete 20210909_dunnp it_dri llingswnnaryrep ort. docx July 2021 TELESTO Currently, there are four (three active, one plugged and abandoned) oil and gas wells on the Site, owned and operated by Kerr McGee Oil & Gas Onshore LP. An associated separator and tank battery is also located on the property. According to the Colorado Division of Water Resources' (CDWR's) well permit database, there is 1 permitted water wells on Site and eight permitted water wells located within t/2 mile. 1.1.1 Subsurface Material The subsurface materials encountered during drilling are fairly uniform throughout the Site. They consist of a sandy clay topsoil ranging up to a depth of 4 feet with an average thickness of 2 feet. Beneath the layer of topsoil, clayey sand and gravel was encountered from 6 -inches to 10 feet BGS. Below this layer, intermittent layers of clean sand, pebbles, gravels and cobbles were encountered ranging in depths from 6" to 32 feet BGS. The size of the gravel/cobbles ranged from 1 inch to 4 inches. Beneath the sand and gravel was a weathered claystone/shale which overlaid a harder claystone/shale bedrock. The depth to bedrock ranged from 23.5 feet to 33 feet. 2.0 DRILLING Prior to drilling, Telesto submitted notice of intent to drill form GWS-51, in accordance with Water Well Construction Rules, 2 CCR-402-2 Rule 6.3 with the Colorado State Engineer's Office (Attachment 2). Authentic Drilling Company (License #: 1510) drilled and installed all 10 monitoring wells on Site. The drilling activities occurred from May 4th, to May 7th, 2021. All boreholes were advanced using a hollow stem auger methodology. The drilling depths ranged from 25 feet to 34 feet below ground surface (BGS). Table 1 below summaries the drilling locations, total depth and depth to groundwater.

All borehole geologic logs and well construction logs are presented in Attachment 3. While drilling the boreholes for the monitoring wells, Telesto collected sediment samples from the alluvium and underlying bedrock for each borehole. The samples were prepared and sent to Analytical Laboratory Services —Fort Collins, Colorado (ALS) to analyze selected samples for the Environmental Protection Agency's Synthetic Precipitation Leaching Procedure (SPLP) and whole -rock chemical analysis. 2.2 Well Construction Telesto submitted monitoring/observation water well permits (CDWR Form GWS-46), which included lithology logs and well construction reports (GWS-31), to the CDWR (Attachment 4). The following well completion design was used for all the monitoring wells: • Boreholes advanced using a hollow stem auger methodology • Backfill hole below bedrock to 1' above alluvium -bedrock contact with silica sand Loveland Ready -Mix Concrete 20210909_dunnp it_dri llingswnnaryrep ort. docx 3 July 2021 TELESTO • Two-inch diameter schedule 40 PVC casing • Two-inch diameter 0.01 slot PVC well screen throughout the entire alluvium gravel deposit (20 to 35 feet) to approximately 1 -foot above the water table • 10/20 Silica Sand used a filter pack from the bottom of well to two -feet above the screened interval • Bentonite chips, grout or neat cement added above filter pack to ground surface • Two -foot by two -foot concrete pad and well monument installed at the ground surface • Three foot steel protective stickup surface completion set 2.3 Well Development All monitoring wells were developed following well completion. The wells were purged long enough to remove as much excess sediment as possible from the groundwater and allow for the collection of an accurate representative groundwater sample.

Project Director AFU:mf SCOPE This report presents the results of a gravel resource evaluation prepared for the parcel of land as shown on Exhibit No. 1. The objective of this investi- gation was to determine the extent and quality of the gravel aggregates found on the site. Data gathered through field and laboratory work are summarized in Exhibit Nos. 1 through 7. FIELD INVESTIGATION The field investigation included both test borings and aggregate sampling from caisson holes. The test borings were made between the sixth and eighth of March, 1978 at the locations shown on Exhibit No. 1. The thirty-seven test borings were made with a CME - Model 55 mounted with a four -inch continuous flight auger. As each boring proceeded, a log was kept on which was recorded such information as a description of materials encountered, their respective depths, depth to the groundwater table and any other pertinent data. These logs are reproduced in Exhibit No. 2. The caisson holes were made on the 20, 21, 24 and 25 of April, 1978 at the locations shown on Exhibit No. 1. The four holes were drilled with a 30 - inch power auger to the approximate depth of the water table and the remaining depth of the hole with a 30 -inch diameter mud bucket. Samples of aggregate were taken at various depths throughout the depths of the hole for use in laboratory tests. SITE CONDITIONS .The site under investigation is located in the Northeast Quarter of Section 3, Township 4 North, Range 67 West and lies south of the Union Pacific Railroad (refer to Exhibit No. 1). Presently the site is being utilized as a pasture for cattle and horses. The topography is generally flat with some rolling areas. The surface drainage is in a southeasterly direction. The parcel of land is divided by the Big Thompson River. GROUNDWATER Groundwater was encountered throughout the site as evidenced by the boring logs. The average depth to groundwater from all the test borings was 5.9 -feet. The average elevation of the water table as determined from the boring logs was 4,735. SUBSURFACE MATERIALS The field investigation and laboratory tests for this site indicate the materials encountered are fairly uniform over the area. They consist of a layer of topsoil ranging up to a depth of three feet with an average thick- ness of slightly over 11 inches. Beneath this layer of topsoil, silty or clayey sand and gravel was recorded from one-half foot to ten and a half feet below the surface with an average thickness of this layer being approx- imately four feet. Below this layer, intermittent layers of clean sand, gravel and cobbles were encountered ranging in depth from eight to 31 feet with a total average thickness of 22 feet. A firm clay was then encountered which overlaid a hard claystone bedrock. LABORATORY INVESTIGATIONS The intent of the laboratory investigations was to determine the proportions of sand and gravel at the site and their respective qualities as they relate to construction material standards. The materials used in the laboratory tests were. obtained from the caisson holes and taken from depths which re- flected approximate changes in the various layers of materials. The five tests which were conducted on the aggregate samples with their accompanying ASTM designation are: (1) Sieve Analysis of Fine and Coarse Aggregate, ASTM C 136-76; (2) Specific Gravity and Absorption of Coarse and Fine Aggregate, ASTM C 127-77 and ASTM C 128-73; (3) Soundness of Aggregates by Use of Magnesium Sulfate, ASTM C88-76; (4) Abrasion Resistance of Large and Small Coarse Aggregate by Use of the Los Angeles Machine, ASTM C 535-69 (1975) and ASTM C 131-76, and (5) the Potential Reactivity of Aggregates by the Chemical Method, ASTM C 289-71 (1976). The objective of the sieve analysis is to determine the particle size dis- tribution of fine and coarse aggregates by screening a weighed sample of dry aggregate through a series of sieves of progressively smaller openings. From this information the percentages of material retained on each sieve can be calculated on the basis of total sample weight. The purpose of the specific gravity test is to determine the ratio of ag- gregate weight to the weight of an equal volume of water. It should be noted that specific gravity is not a measure of aggregate quality but rather necessary in certain, design and control calculations. The basic procedure for determining aggregate specific gravity is to take the ratio of the aggregate sample's saturated surface - dry weight to its weight in water. The absorption test determines the quantity of water that a given amount of aggregate will absorb when submerged. It is found by taking the dif- ference between a sample's saturated surface - dry weight and its oven -dry weight as a percentage. The soundness test provides an indication as to structural weaknesses which may be present in an aggregate. It is used to measure the potential freeze - thaw resistance of the aggregate by subjecting it to several cycles of immersion in magnesium sulfate after which the sample is oven -dried. Salt Crystal growth within the aggregate's pores is used to simulate the pres- sures exerted on the aggregate when water freezes and expands within the pores. The soundness is obtained by finding the percentage weight loss of the aggregate after five cycles. The Los Angeles Abrasion Test provides important information concerning the toughness and hardness of an aggregate. It can be used in estimating the breakdown that will occur when aggregates are handled, stockpiled and trans- ported. The basic test calls for putting an aggregate sample into a steel drum with an abrasive charge (12 steel spheres). The drum is then rotated a certain number of revolutions after which the percentage of material worn away during the test is determined. The final test considered within this report is the potential chemical re- activity. Aggregates with certain chemical constituents will react with the alkalies in Portland cement to cause abnormal expansion and hair -line crack- ing of the concrete. Potentially reactive siliceous aggregates are identi- fied by their degree of reaction with a sodium hydroxide solution. AGGREGATE QUANTITIES A topographical survey was made of the subject site by means of aerial photo- graphy. The purpose of this survey was to obtain existing ground elevations in order to plot cross sections for quantity calculations. By using these cross sections and through interpolation of the Test Hole Logs, the total amount of coarse and fine aggregate was found to be in the'order of 2.8 million cubic yards. Of this total approximately 1.25 million cubic yards is coarse aggregate. It should be pointed out that these numbers are approximate and more extensive drilling would have to be performed in order to achieve more accuracy. The aggregate size distribution has been tabulated on Exhibit No. 3. LIMITATIONS Test Borings for this investigation were spaced to obtain a reasonably accurate representation of subsurface conditions. Variations from the conditions disclosed which were not indicated by the test explorations frequently occur and quite often these variations are sufficient to neces- sitate additional testing. The judgements and results in this report are based upon our evaluation of actual physical conditions encountered at the location indicated herein, and upon our extrapolations thereof. We do not warrant the accuracy of such extrapolations beyond the limits of the tests performed or where actual physical conditions were not observed. Under the above conditions, it is important that we inspect the subsurface materials exposed in excavations to take advantage of all opportunities to recognize differing conditions and minizing the risk of having undetected conditions which would affect the performance of the facility. Should you have any questions or are in need of further information re- garding this report, please feel free to contact us. Respectfully, C -E MAGUIRE, INC.

"Report Limit" is the MDC U or ND - Result is less than the sample specific MDC. Y1 - Chemical Yield is in control at 100-110%. Quantitative yield is assumed. Y2 - Chemical Yield outside default limits. W - DER is greater than Warning Limit of 1.42 *-Aliquot Basis is 'As Received' while the Report Basis is 'Dry Weight'. # - Aliquot Basis is 'Dry Weight' while the Report Basis is 'As Received'. G - Sample density differs by more than 15% of LCS density. D - DER is greater than Control Limit M - Requested MDC not met. M3 - The requested MDC was not met, but the reported activity is greater than the reported MDC. L - LCS Recovery below lower control limit. H - LCS Recovery above upper control limit. P - LCS, Matrix Spike Recovery within control limits. N - Matrix Spike Recovery outside control limits NC - Not Calculated for duplicate results less than 5 times MDC B - Analyte concentration greater than MDC. B3 - Analyte concentration greater than MDC but less than Requested MDC. Inorganics: B - Result is less than the requested reporting limit but greater than the instrument method detection limit (MDL). U or ND - Indicates that the compound was analyzed for but not detected. E - The reported value is estimated because of the presence of interference. An explanatory note may be included in the narrative. M - Duplicate injection precision was not met. N - Spiked sample recovery not within control limits. A post spike is analyzed for all ICP analyses when the matrix spike and or spike duplicate fail and the native sample concentration is less than four times the spike added concentration. Z - Spiked recovery not within control limits. An explanatory note may be included in the narrative. * - Duplicate analysis (relative percent difference) not within control limits. S - SAR value is estimated as one or more analytes used in the calculation were not detected above the detection limit. Organics: U or ND - Indicates that the compound was analyzed for but not detected. B - Analyte is detected in the associated method blank as well as in the sample. It indicates probable blank contamination and warns the data user. E - Analyte concentration exceeds the upper level of the calibration range. J - Estimated value. The result is less than the reporting limit but greater than the instrument method detection limit (MDL). A - A tentatively identified compound is a suspected aldol-condensation product. X - The analyte was diluted below an accurate quantitation level. * - The spike recovery is equal to or outside the control criteria used. + - The relative percent difference (RPD) equals or exceeds the control criteria. G - A pattern resembling gasoline was detected in this sample. D - A pattern resembling diesel was detected in this sample. M - A pattern resembling motor oil was detected in this sample. C - A pattern resembling crude oil was detected in this sample. 4 - A pattern resembling JP -4 was detected in this sample. 5 - A pattern resembling JP -5 was detected in this sample. H - Indicates that the fuel pattern was in the heavier end of the retention time window for the analyte of interest. L - Indicates that the fuel pattern was in the lighter end of the retention time window for the analyte of interest. Z - This flag indicates that a significant fraction of the reported result did not resemble the patterns of any of the following petroleum hydrocarbon products: - gasoline - JP -8 - diesel - mineral spirits -

I C II Job No: 360100-006-01e Client: LRM Page 1 of 9 Task: Short Term Aquifer Tests Computed By: Tim Gerken Date: 7/24/21 Dunn Pit Checked By: Mark Birch Date: 7/30/21 Problem Statement: Calculation Documentation To assess potential impacts of the Loveland Ready -Mix Concrete, Inc. (LRM) Dunn Pit development on groundwater, a series of short-term aquifer tests were performed on 2 wells at the Proposed Dunn Pit. The tests were performed on 2 monitoring wells (MW -03, MW -09) installed by LRM with Telesto Solutions, Inc. (Telesto) oversight in May of 2021 to provide robust hydraulic conductivity data for the aggregate resource (alluvium) for the site. Objective : The main objective of the short-term aquifer testing program was to obtain reasonable estimates of the hydraulic conductivity of the alluvium at the Proposed Dunn Pit. Given this objective, several simplifying assumptions were used in analyzing the aquifer test data: Assumptions and Approach : 1. Groundwater flow to the wells is horizontal and vertical components of flow are negligible 2. The bottom of the well screen represents the bottom of the aquifer 3. Flow to the well is radial and the aquifer is of "seemingly" infinite lateral extent 4. The aquifer is homogeneous and isotropic 5. The drainable porosity of the well sandpack material is 0.25 6. Due to water table drawdown near the well, the appropriate aquifer thickness is given by: b = hw + hi12 where: b = The representative aquifer thickness hw = The height of water in the well at the end of the test h; = The initial height of water in the well. Analysis: Based on the assumptions above, Telesto used methods to analyze aquifer tests that were based, on the Theis solution of radial flow to a well in an infinite aquifer: s = Q/4rrT * W(u) (1) where: s = drawdown at an observation point (L) Q = pumping rate of the well (L3/T) T = aquifer transmissivity (L2/T) W(u) = Theis well function u = variable defined by: u = r2S/4Tt where: r = radius of interest (L) S = storage coefficient of the aquifer t = time (T) (2) TELESTO 5 O L U T I O N 5• I r, C n K p .

Thus, if drawdown (s) data are plotted against log time (t) on semi -log paper, and the pumping test has been performed for an adequate amount of time, the data should approximate a straight line. Through either a linear regression analysis or visual fitting of a straight line to this data, the aquifer transmissivity can then be calculated from the following equation: where: 2.303 Q T- 4TcOs As is the change in drawdown over 1 log cycle of time. (5) By definition, the transmissivity is a product of the aquifer thickness (b) and the hydraulic conductivity (K). Thus, the hydraulic conductivity can be estimated by: _T K b (6) McWhorter and Sunada (1977) describe this procedure, called the Jacob method, in more detail. This type of analysis was applicable to the 2 tests performed at Dunn Pit . Figures 1 and 2 and Table 1 display the semi -log plots and results of this method used on the Dunn Pit wells.

Assumptions 2 and 3 are appropriate due to the short-term nature of the aquifer tests performed at the Proposed Dunn Site. Assumption 5 is based on porosity values cited in the literature for a clean sand (McWhorter and Sunada [1977], Freeze and Cherry [1979], and Spitz and Moreno [1996]). Assumption 6 is based on the Dupuit-Forcheimer assumption and is explained in McWhorter and Sunada (1977). Conclusions: The calculation set achieved the objectives set forth through robust use of the available data and design information. The short-term aquifer tests provided a quick and acceptably accurate method to gain insight into hydraulic properties of the alluvium at the Dunn Pit. These properties can be used to estimate groundwater flow in the groundwater model for the Proposed Dunn Pit. References: Freeze, R. Allan and John A. Cherry. 1979. Groundwater. Prentice Hall, Inc.

March 2022 — Rev 2 1.0 INTRODUCTION In September 2021, Loveland Ready Mix (LRM) submitted an application to the Colorado Division of Reclamation Mining and Safety (DRMS) to permit the proposed Dunn Pit. As part of the approval process the Division requires LRM submit a groundwater quality monitoring plan and sufficient data to determine baseline groundwater quality and demonstrate the site complies with CDPHE Water Quality Control Commission (WQCC) Regulation 41: Basic Standards for Groundwater during the tenure of the mine and reclamation. This Sampling and Analysis Plan (SAP) describes the sampling and analysis methods and monitoring schedule for collecting groundwater elevation and quality samples at the Dunn Pit (Site). The SAP includes procedures for: • Collecting ground water samples • Chemical analysis of ground water samples • Documenting data collection activities • Analytical methods and detection levels • Quality Assurance and Quality Control (QA/QC Figure 1 depicts the site and monitoring well locations. Groundwater elevation contours for the area are also included in Figure 1. 2.0 OBJECTIVE The objective of this SAP is ensure consistent and accurate data collection for baseline and operational groundwater characterization underlying the Site). Quality data collection helps ensure mining and reclamation activities maintain existing groundwater quality and uses. 3.0 STANDARD OPERATING PROCEDURES Standard Operating Procedures (SOPs) are included in Attachment 1. These SOPs include: Loveland Ready -Mix Concrete, Inc. aped_303300318 updated Inn dnnngwsap rev3final 1 Telesto Solutions, Inc. March 2022 — Rev 2 • SOP #1 Equipment Decontamination • SOP #2 Monitoring Well Water Level Measurement • SOP #5 Ground Water Sample Collection • SOP #7 Sample Documentation, Handling, Packaging, and Chain of Custody • SOP #9 Field Parameter Instrument Calibration and Measurement 4.0 DECONTAMINATION PROCEDURES Extraneous materials can contaminate water samples during a sampling program. While well development and purging procedures may help to remove contaminants, these procedures may not be completely adequate, therefore laboratory test results of the collected water samples maybe inaccurate due to outside contamination. SOP #1 presents general decontamination procedures. All equipment that will contact sampled media requires decontamination. General procedures that apply to decontamination include: • Dress in suitable safety equipment to reduce personal exposure • Wear clean or new rubber or nitrile gloves during decontamination activities and when handling decontaminated equipment • Use new equipment, such as disposable filters and silicon tubing that is certified clean by the manufacturer • Decontaminate all wash/rinse tubs before initial use • Replace rinse and detergent waters, unless in garden sprayers, with new solutions between sample locations. In some cases, new solutions may be needed between samples in the same location • Following decontamination, place equipment in a clean area or on clean plastic sheeting to prevent contact with contaminated soil. If not used immediately, cover equipment, or wrap it in plastic sheeting or heavy duty trash bags to minimize potential airborne contamination. 5.0 GROUND MONITORING Table 1 lists the site monitoring wells and their purpose. 5.1 Water Level Monitoring Monitoring wells MW -01 through MW -10 are for depth to groundwater monitoring. Combine depth to groundwater measurements with well stickup and site ground surface elevation to provide accurate portrayal of ground water elevations. Follow SOP #2 when Loveland Ready -Mix Concrete, Inc. aped_303300318 updated Inn dnnngwsap rev3final 2 Telesto Solutions, Inc. March 2022 — Rev 2 collecting depth -to -water information. Collect depth -to -water information monthly for one year, and quarterly thereafter. 5.2 Water Quality Monitoring Monitoring wells MW -03, MW -05, MW -07, MW -08, and MW -09 serve a dual purpose of depth to water level and groundwater quality sampling. Collect ground water samples from these monitoring wells (also shown Figure 1) on a quarterly basis before and during mining until otherwise determined. Appendix A of the Groundwater Baseline Report includes well completion logs for all monitoring wells. Ensure all ground water sampling equipment which will contact the ground water sample are decontaminated following the procedures specified in SOP #1 or are new and certified clean by the manufacturer. Prior to sample collection, sampler will collect a water well level measurement per the procedures outlined in SOP #2. Purge a minimum of three casing volume prior to sampling. If suspected that a well will not yield three well volumes during purging, collect field pH, specific conductivity, and temperature during purging, and sample once three consecutive measurements are consistent (i.e., stabilized). The monitoring wells listed in Table 1 should yield sufficient water to allow for three casing volumes before sampling. Once field parameters have stabilized and or three well volumes have been removed, collect groundwater samples according to SOP#5 and #7. Table 2 lists the field parameters (i.e., pH, specific conductivity, and temperature) and laboratory water quality parameters for measurement. 6.0 SAMPLE DOCUMENTATION, HANDLING, PACKAGING, AND CHAIN OF CUSTODY The standard operating procedures for sample documentation, handling, packaging, and chain of custody are presented in SOP #7. Follow sample custody procedures to maintain sample integrity during collection, transportation, and storage prior to analysis. Minimize the number of individuals handling the samples. The field sampler is personally Loveland Ready -Mix Concrete, Inc. aped_303300318 updated Inn dnnngwsap rev3final 3 Telesto Solutions, Inc. March 2022 — Rev 2 responsible for collection and custody of the samples until they are transferred to the laboratory. 7.0 FIELD QUALITY ASSURANCE AND QUALITY CONTROL PROCEDURES 7.1 Field Parameter Instrument Calibration and Measurement Field parameter instruments and calibration/measurement procedures are presented in SOP #9. Ground water field parameters include pH, specific conductivity, and temperature. Calibrate field parameter instruments before initial measurements and as needed throughout the day as required to maintain instrument accuracy. 7.2 Field Quality Assurance/Quality Control Samples The primary sample and field quality control samples are listed in Table 2. Quality control samples include field duplicates, field blanks and rinsate samples. QA/QC samples help identify potential sources of sample contamination and help evaluate potential error introduced by sample collection and handling. Label all QA/QC samples with QA/QC identification numbers (i.e., "02" for duplicate samples, "03" for field blanks, "04" for rinsate) and send to the laboratory with the other samples for analyses. 7.2.1 Duplicate Samples Collect duplicate samples to check for the natural sample variance and the consistency of field techniques and laboratory analysis. Collect duplicate samples side -by -side with primary samples. First collect primary samples, and then collect the duplicate samples. Fill all bottles and submit to the same analysis. Utilize different filter and tubing will be used for the primary and duplicate samples. Handle the duplicate water sample in the same manner as the primary sample. The duplicate sample will be assigned the QA/QC identification number "02," stored in an iced cooler, and shipped promptly to the laboratory so that analyses can be performed within required holding times. Collect one duplicate sample per sampling episode. Loveland Ready -Mix Concrete, Inc. aped_303300318 updated Inn dnnngwsap rev3final 4 Telesto Solutions, Inc. March 2022 — Rev 2 7.2.2 Field Blanks Collect field blanks by filling sample containers in the field with deionized water (preferably laboratory prepared deionized water). Assign the sample QA/QC identification number "03," store in an iced cooler, and ship to the laboratory with all other samples. Collect one field blank per sampling event. 7.2.3 Rinsate Samples Collect an equipment rinsate sample from sampling equipment to check that decontamination procedures are effective. Collect a rinsate sample from the decontaminated sampling equipment (bailer or pump) and filter equipment before using it to obtain the sample. To collect a rinsate sample from a pump, pump the final deionized water rinse through the discharge hose and clean filter into sample bottles. Analyze rinsate sample for the same parameters to which the groundwater samples are subjected. Assign the rinsate sample the QA/QC sample identification number "04," store it in an iced cooler, and ship promptly to the laboratory so that analyses can be performed within the holding times. Collect one rinsate sample will be collected per sampling event. There is no need to collect a rinsate sample if using disposal bailers or sampling equipment. 7.3 Laboratory Quality Assurance/Quality Control 7.3.1 Matrix Spike Samples Analyze matrix spike (MS) samples to evaluate potential matrix effects on sample analyses for all inorganic parameters. The laboratory will analyze matrix spike samples for the inorganic parameters. The laboratory will split the matrix spike samples an existing sample. 7.3.2 Laboratory Replicate The laboratory will create replicate samples from primary sample splits, and analyze these as part of the laboratory's QA/QC program. The laboratory replicate will not require a separate sample volume. Loveland Ready -Mix Concrete, Inc. aped_303300318 updated Inn dnnngwsap rev3final 5 Telesto Solutions, Inc. March 2022 — Rev 2 8.0 SAMPLING SCHEDULE AND DATA MANAGEMENT Prior to any mining activities exposing groundwater at the Site, LRM will collect monthly depth -to -water and quarterly baseline water quality samples for a period of five quarters to confirm the baseline water quality of the underlying aquifer (Big Thompson Alluvial Aquifer). If after five quarters of sampling, water quality data indicates no reportable differences to analyte detection levels, LRM will submit documentation to the Division demonstrating the consistency in water quality results provides rational and compelling evidence sufficient to establish baseline conditions. With document submittal, LRM will request a sample reduction through a submittal of a Technical Revision with the Division approval to begin mining and/or dewatering operations without additional background monitoring. During active mining operations and reclamation, LRM will work with DRMS to develop a meaningful program to continue groundwater monitoring on a regular basis and with an annual report submitted each year. Active mining and reclamation are expected to last 30 - years. Loveland Ready -Mix Concrete, Inc. aped_303300318 updated Inn dnnngwsap rev3final 6 Telesto Solutions, Inc.

September, 2009 1 Equipment Decontamination Standard Operating Procedure No. I 1.0 PURPOSE AND SCOPE The purpose of this document is to define the standard procedure for decontamination. The American Society for Testing and Materials (ASTM) Standard Practice for Decontamination of Field Equipment Used at Nonradioactive Waste Sites (D 5088-90) was used as a guide in preparing this Standard Operating Procedure (SOP). The overall objective of multimedia sampling programs is to obtain samples that accurately depict the chemical, physical, and/or biological conditions at the sampling site. Extraneous contaminants can be brought onto the sampling location and/or be introduced into the medium of interest during the sampling program (e.g., by bailing or pumping ground water with equipment that was previously contaminated at another site). Trace quantities of these contaminants can thus infect a sample and lead to false positive analytical results and, ultimately, to an incorrect assessment of the contaminant conditions at the site. Decontamination of sampling equipment (e.g., bailers, pumps, tubing, and soil and sediment sampling equipment) and field support equipment (e.g., drill rigs and vehicles) is therefore required to ensure that sampling cross - contamination is prevented and that on -site contaminants are not carried off -site. 2.0 RELATED STANDARD OPERATING PROCEDURES This procedure is intended to be used with the following SOP: SOP # Title 7 Sample Documentation, Handling, Packaging, and Chain of Custody 3.0 EQUIPMENT NECESSARY FOR DECONTAMINATION The following equipment may be needed to perform decontamination: Telesto Solutions, Inc. September, 2009 1 Equipment Decontamination Standard Operating Procedure No. I • Brushes • Wash tubs (plastic) • Buckets (plastic) • Scrapers • Steam cleaner or hot water washer • Paper towels • Liquinox detergent (or equivalent) • Potable water • Deionized water • Garden type water sprayers • Laboratory wash bottles • Clean plastic sheeting and/or trash bags. 4.0 DECONTAMINATION PROCEDURES 4.1 General Decontamination Procedures for All Equipment Decontaminate all equipment that will contact a sampled media. General procedures that apply to most specific decontamination procedures are listed below. • Dress in suitable safety equipment to reduce personal exposure. • Wear clean or new rubber or latex gloves during decontamination activities and when handling decontaminated equipment. • Do not decontaminate new equipment, such as disposable filters and silicon tubing, that is certified clean by the manufacturer. Telesto Solutions, Inc. September, 2009 2 Equipment Decontamination Standard Operating Procedure No. I • Decontaminate all wash/rinse tubs before intial use and between boreholes. • Replace rinse and detergent waters, unless in garden sprayers, with new solutions between borings or sample locations. In some cases, new solutions may be needed between samples in the same location. • Following decontamination, place equipment in a clean area or on clean plastic sheeting to prevent contact with contaminated soil. If the equipment will not be used immediately, cover the equipment or wrap it in plastic sheeting or heavy duty trash bags to minimize potential airborne contamination. 4.2 Decontaminating Sampling Equipment Decontaminate sampling equipment as follows: 1. Scrape off gross contamination from equipment at the sampling or construction site. 2. For equipment that water will not damage, place the equipment in a wash tub containing Liquinox and potable water or spray the equipment with a Liquinox/potable water solution contained within a garden type sprayer, and scrub the equipment with a bristle brush or similar utensil (if possible). 3. In a second wash tub or using a second garden sprayer, triple rinse equipment with potable water to remove the Liquinox solution. 4. Triple rinse the equipment with deionized water from a garden sprayer laboratory wash bottles, and let the equipment air dry (if possible). 4.3 Decontaminating Submersible Pumps Decontaminate the insides of an electric submersible pump and discharge hose (e.g., a Redi-Flo 2 pump) as follows: or 1. Before performing internal decontamination, remove the Redi-Flo2 internal pump fluid and replace it with deionized water (see the Red-Flo2 owners manual). 2. Pump Liquinox/potable water solution through the pump and hose. Be sure that the volume of solution used is not less than one volume of fluid contained in the Telesto Solutions, Inc. September, 2009 3 Equipment Decontamination Standard Operating Procedure No. I pump and hose. (Note that a Redi-Flo2 pump with 250 feet of 0.5 -inch inner - diameter hose contains 2.55 gallons of fluid.) 3. Pump potable rinse water through the pump and hose. Be sure that the volume of solution used is not less than three times the volume of fluid contained in the pump and hose. 4. Pump deionized rinse water through the pump and hose. Be sure that the volume of solution used is not less than three times the volume of fluid contained in the pump and hose. Decontaminate the outside of the pump and discharge hose as follows: 1. When removing the pump and hose from the well, place the hose reel 10 to 20 feet away from the well to allow the hose to be decontaminated before placing it on the reel. Do not let decontamination fluids enter the well. 2. While removing the pump from the well, wash the outside of the pump and hose with Liquinox/potable water solution and triple rinse it with potable water. 3. Triple rinse the hose with deionized water before placing the hose on the reel and/or triple rinse the hose with deionized water while lowering the pump into the next well. If the pump and hose are exposed to airborn contaminants (e.g., dust and mud), rinse the pump and hose while lowering the pump down the next well. 4.4 Decontaminating Water Level Probes Decontaminate water level probes by using the general decontamination procedures for sampling equipment (Section 4.2) or by wiping them successively with paper towels wetted with Liquinox solution, potable water, and deionized water. Rinse the water level probe with deionized water before use. Store the water level probe in a plastic bag after decontamination. 4.5 Decontaminating Delicate Equipment Telesto Solutions, Inc. September, 2009 4 Equipment Decontamination Standard Operating Procedure No. I Carefully wipe clean equipment that water will damage successively with paper towels wetted with Liquinox solution, potable water, and deionized water. Be sure to avoid damaging the equipment. 4.6 Decontaminating Drilling and Heavy Equipment Decontaminate drilling and heavy equipment as follows: • Dress in suitable safety equipment to reduce personal exposure. • With a flat -bladed scraper, scrape gross contamination or drill cuttings off equipment at the sampling or construction site. • Spray equipment, such as drill rigs, augers, drill bits, and shovels, with a Liquinox/potable water solution using a hot water washer. Be sure to adequately clean the insides of the hollow -stem augers and backhoe buckets. • Rinse the equipment with potable water. • Place drilling equipment on the clean drill rig and move it to a clean area. If the equipment will not be re -used immediately, store it in a designated clean area. 4.7 Disposing of Decontamination Solution Dispose of used wash and rinse solutions at a location that will not bias subsequent samples. 5.0 DOCUMENTATION Be sure to document the decontamination of sampling and drilling equipment. Record the documentation with black waterproof ink in the sampler's field notebook with consecutively numbered pages. This documentation should include the following: Telesto Solutions, Inc. September, 2009 5 Equipment Decontamination Standard Operating Procedure No. I • The personnel who performed the decontamination • Date • Decontamination procedures and observations • Rinsate sample collection procedure (if collected). 6.0 QUALITY ASSURANCE REQUIREMENTS To verify the effectiveness of the decontamination procedures, collect equipment rinsate samples from the decontaminated sampling equipment as follows: • Run deionized water through or over a representative decontaminated sampling tool (such as a split spoon sampler or bailer) and collect the rinsate water in sample bottles. • Filter, preserve, handle, and analyze rinsate samples for the same parameters as primary samples collected at the site. Refer to SOP #7 for sample documentation, handling, packaging, and chain -of -custody procedures. • Record the rinsate procedure, including the sample number, in the field notebook. • Send the bottles to the laboratory for analysis. Collect equipment rinsate samples at the following frequencies: • If more than 20 field samples were collected, collect one rinsate sample per 20 field samples collected. • If less than 20 field samples were collected in the sampling event, collect at least one rinsate sample per sampling method used. • When using more than one sampling method or type of equipment, collect at least one rinsate sample from each type of device that was used to obtain samples (e.g., if both a bailer and a electric submersible pump were used to collect ground water samples, collect a rinsate sample from both devices at a minimum frequency of 1 each per 20 samples).

This Standard Operating Procedure (SOP) describes equipment and field procedures necessary to collect water level measurements. 2.0 RELATED STANDARD OPERATING PROCEDURES This procedure is intended to be used with the following SOP: SOP # Title 1 Equipment Decontamination 3.0 NECESSARY EQUIPMENT The equipment necessary to measure water levels includes: • Electric water level probe capable of producing measurements to the nearest 0.01 foot • Replacement batteries for water level probe • Field logbook, field data sheets, and black pen • Engineers tape (marked in increments of 10ths and 100ths of a foot) • Additional stainless steel weight • Paper cups and/or turkey baster • Paper towels • Liquinox soap • Potable water • Sprayer filled with deionized water Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a_sop02_wl measure.doc 1 January 20 Monitoring Well Water Level Measurement Standard Operating Procedure # 2 • Appropriate health and safety equipment, including at least safety glasses and latex gloves. 4.0 WATER LEVEL MEASUREMENT PROCEDURES This section gives the sequence of events to follow when measuring water levels. • Before mobilization to the site, obtain the following: previous water level data and survey data if available (data should include description of measurement point location and survey point description) well completion data, including total depth, well casing stickup, and protective casing stickup if wells are locked, obtain the appropriate key. • Wear appropriate health and safety equipment, as described in the Health and Safety Plan when opening and measuring wells and performing decontamination. At a minimum, wear safety glasses and latex gloves. (Latex gloves are required to prevent cross contamination.) • To minimize potential cross contamination, measure the wells in order of cleanest to most contaminated. • Before taking measurements, decontaminate the water level probe according to SOP #1 and Section 5 of this SOP. • Unlock and open the well. If the water level is above the top of the well and cap, evacuate the water with a paper cup or a turkey baster. Follow all health and safety procedures and if necessary, let the well vent any gasses that may be present in the well casing. If you observe either a negative or positive pressure when opening the well, let the well stabilize before measuring the water level. Stabilization could take several minutes, hours, or days, depending on well characteristics. • Test the water level probe to verify that it is working properly. Push the circuit test button to verify that the light/buzzer is working. This button tests only the light/buzzer and does not test the other parts of the water level probe. Dip the tip of the water level probe into water to verify that the water level probe is working properly. Note that deionized water, due to its low conductivity, will not trigger a response. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a_sop02_wl measure.doc 2 January 20 Monitoring Well Water Level Measurement Standard Operating Procedure # 2 • After opening the well cover, locate the measuring point for water level measurements. The measuring point for the water level is usually the top of the well casing, not the protective casing, but it can vary between wells and programs. Some programs will specify on which side of the well casing (i.e., the north side) to locate the measuring point or will specify the highest point of the casing if it is not cut evenly. If not already marked and described, the measuring point should be marked and described for easy identification. If possible, the measuring point should be the same as the survey point. • To measure the static water level, lower the water level probe into the well until the buzzer/light indicates that the probe tip has contacted water. By raising and lowering the water level probe and adjusting the sensitivity to indicate when the probe is contacting the water, the depth to water should be measured to the nearest 0.01 foot. Record the water level depth below the measuring point in the field book or data sheet. Then recheck the measurement before removing the water level probe from the well. Compare the most recent measurement with past measurements and verify that the new measurement is reasonable before leaving the well. If the measurement does not seem reasonable, measure the water level again. • If the well is dry, record the maximum depth measured (e.g., dry to 44.34 feet). • Measuring the total well depth will help identify the well, indicate if there is well damage or accumulated sediment in the well, and provide data to calculate saturated borehole volume prior to purging the well. If water contacts cuts or nicks in the line and causes a "short" in the line, you may need to repair and/or clean and dry the line before reuse. (Note: Because measuring total depth in deep wells with high water levels can force water around seals in tips and may cause shorting, the tip may need to be disassembled and dried.) The total well depth should be measured unless a recent total depth measurement has been fully documented. If the measuring point on the well probe is not at the tip of the probe, adjust the total depth measurement to account for the distance between the water measurement point and the tip of the probe. • When raising or lowering the water level probe from the well, exercise great care to avoid pulling the probe wire over the well casing or the protective casing. Even PVC pipe can damage the water level probe if it is not handled properly. • Especially on deep wells, you may need an additional weight to lower the water level probe to the water level. A non -contaminating, long, narrow weight (e.g., a stainless steel rod) should be used. Tape the weight to the water level probe line with plastic electrical tape only when not measuring organics, and remove the weight prior to decontamination. Excessive weight could damage the water level probe by stretching or even breaking the line. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a_sop02_wl measure.doc 3 January 20 Monitoring Well Water Level Measurement Standard Operating Procedure # 2 • Measure the distance that the protective casing sticks up above ground level and the distance from the measuring point on the top of the well casing to the top of the protective casing. • Wells with submersible pumps or other installed equipment probably should not be measured unless a tube specifically designed for water level measurements is present. The risk of losing the water level probe and/or damaging equipment installed in the well is considerable. Before attempting to measure a water level in a well with any installed equipment, obtain the project manager's approval. 5.0 DECONTAMINATION Decontaminate the water level indicator before measuring the water level in the first well and after measuring the levels in all wells. Decontaminate the probe according to SOP #1. Decontamination requirements will vary depending on the contaminants present and their concentrations, and some sites may require decontamination of the probe between measurements at each well. At mining sites where low-level inorganic background parameters are being monitored, the decontamination procedure may consist of the following: (1) wiping the well probe line, as it is removed from the well, successively with paper towels that have been wetted with Liquinox solution, potable water, and deionized water and (2) rinsing the entire reel with deionized water before use. Although this method is efficient, it may not be acceptable at all sites. Other acceptable decontamination procedures are specified in SOP #1. The decontamination procedure used should be approved by the project manager before use. Once decontaminated, the water level probe should be either placed in a clean plastic bag or used immediately. If the water level probe has contacted especially corrosive fluids (e.g., water with high or low pH values, high chlorides concentrations, or high TDS concentrations), at a minimum, thoroughly rinse the water level probe immediately after use to protect the water level probe from damage. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a_sop02_wl measure.doc 4 January 20 Monitoring Well Water Level Measurement Standard Operating Procedure # 2 6.0 DOCUMENTATION This section describes the documentation necessary for water level monitoring. Record at least the following information in the field book or on the ground water data sheets for each well: • Personnel who performed the measurement • Date • Time • Well number • Depth to water from measurement point • Depth to well bottom from measurement point • Distance from the well probe's water level measurement point to the well probe tip to correct total depth measurements • Distance from top of protective casing to ground surface • Distance from measuring point on top of the well casing to the top of protective casing • Description of the measurement point location • Description of the decontamination procedure • Well probe's identification number • All calculations performed. The field notebook used during water level measurement activities will include any other observations made while measuring water levels. 7.0 CALIBRATION The water level measurement probe cord should be calibrated at least annually or more often as needed to ensure the desired accuracy. The calibration check consists of laying out 100 feet of steel Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a_sop02_wl measure.doc 5 January 20 Monitoring Well Water Level Measurement Standard Operating Procedure # 2 tape next to 100 feet of the probe cord. At 2 -foot intervals, note any measurement discrepancies between the two. The probe cord shall be rechecked if it may have been stretched or damaged during water level measurements.

The amount of water that that needs to be purged and how to determine that the resulting sample will be representative of the formation is a frequently debated issue. The two most common methods are purging a set number of saturated borehole volumes and/or casing volumes, usually between 3 and 10, and demonstrating the stability of field parameters (e.g., pH, conductivity, temperature, and turbidity) over a specified volume. Although this SOP discusses a minimum purge volume and stability of field parameters, the best procedure to help collect a representative sample requires on -site evaluation of all field conditions, which includes purge volume, stabilization of field parameters, well construction, hydrologic properties of the formation, and parameters of interest. Due to the variability of site conditions, no one procedure can ensure that a representative sample will be collected without the possibility of over- or under -purging some wells. 4.2 Calculating Saturated Borehole Volume Monitoring wells should be purged before sampling so that representative ground water is sampled, not the potentially biased water stored in the well casing and filterpack. Because the representativeness of stored water is questionable, stored water should be purged from the monitoring well before collecting samples. Removing all stored water in most cases is not feasible or practical. Therefore, before collecting ground water samples, purge an undetermined amount of water from the monitoring well until representative formation water can be sampled. The amount of water to purge will vary from well to well based on specific well characteristics. No one method of calculating the required purge volume will always work. The usual method to estimate purge volumes is to calculate a number of casing volumes or saturated borehole volumes. Casing volumes account for only the water in the well casing and does not account for the water in Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 6 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 the annular borehole space, which is independent of the casing size. Calculating the saturated borehole volume accounts for all the water within the borehole and casing. If purging procedures were completely efficient, the saturated borehole volume would be the minimum volume of water to purge to remove the potentially biased water from the borehole. Because mixing does occur, the minimum purge volume must be greater than one saturated borehole volume. The degree of mixing within the borehole during purging is difficult to estimate and, therefore, the range of recommended purge volumes varies from 3 to 10 saturated borehole volumes. Three saturated borehole volumes has been selected as the best way to estimate purge volumes. Some wells will require purging more than three saturated borehole volumes and some less. The saturated borehole volume calculation formula is presented in Figure 1. Figure 2 presents a sample saturated borehole volume calculation and a blank form to calculate specific saturated borehole volume. The basic formula is volume equals pi times the radius squared times depth (V=mr2d). To calculate saturated borehole volume, the casing and borehole radii and the height of water in the casing and the filter pack must be known. Measure the water level in the field, and obtain the borehole and casing radii from the well completion data. Figure 2 presents a sample saturated borehole volume calculation, as described below: • Equation (a) shows how to calculate the casing radius in feet by dividing the nominal casing diameter in inches by 2 (to convert the diameter to a radius) and dividing the result by 12 (to convert inches to feet). • Equation (b) shows how to calculate the borehole radius in feet by dividing the nominal borehole diameter in inches by 2 (to convert the diameter to a radius) and dividing the result by 12 (to convert inches to feet). • Equation (c) shows how to calculate the casing volume, given the casing radius and height of water in the casing. • Equation (d) shows how to calculate the annular volume, given the annular radius and the height of water in the filter pack. • Equation (e) shows how to calculate the saturated annulus volume by subtracting the casing volume from the borehole volume and multiplying the result by the assumed effective porosity of the annulus. • Equation (f) shows how to calculate the saturated borehole volume by adding the casing volume to the saturated annulus volume and converting cubic feet to gallons. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 7 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 In confined wells and unconfined wells that are screened and filter packed below the water table, the height of water in the casing will exceed the height of water in the filter pack (i.e., hi>h2). In these cases, calculate the height of water in the filter pack based on the top of the filter pack interval, and not the top of the screen interval. To calculate the saturated borehole volume in these cases, substitute the appropriate height of water in feet into Equations C and D. Note that wells have variable amounts of filter pack below the bottom of the screen. The volume of water below the bottom of the screen may be a significant portion of the total saturated borehole volume if there is only a few feet of measurable water in the screen and several feet of filter pack below the bottom of the screen. The saturated borehole volume calculation presented in Figures 1 and 2 does not account for the volume of water in the borehole below the screen. For wells with only minimal amounts of water in the screen, evaluate the amount of water within the borehole below the screen and consider it when purging the well. 4.3 Stability of Field Parameters To demonstrate that you have collected a representative ground water sample, measure field parameters during purging and purge the well until these parameters stabilize. The field parameters measured may include pH, conductivity, temperature, turbidity, Eh, and dissolved oxygen. However, these parameters tend to stabilize at different rates, and field parameters generally stabilize before the chemical parameters that are being sampled. Therefore, the purge volume required for field parameters to stabilize should be considered a minimum purge volume, and laboratory parameters may stabilize only with continued purging. In order to demonstrate that parameters have stabilized, establish the acceptable range of field parameter values and the volume of water between field parameter measurements. The acceptable range for most field parameter measurements is generally 10 percent of the value for conductivity, temperature, turbidity, Eh, and dissolved oxygen, and 0.1 units for pH. Demonstrate stabilization over a minimum volume of one saturated borehole volume. Document that the measurements do Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 8 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 not fluctuate more than 10 percent or 0.1 pH units between the end points. Collect as many field parameter readings as practical between the end points (i.e., one reading at every 1/4 to 1/2 saturated borehole volume). Calibrate the pH and conductivity meters before use every day. Record calibration times and appropriate readings in the field notebook. Refer to SOP #9 for specific instructions on calibrating the pH and conductivity meters. 4.4 Purge Rates and Pump Placement Do not let the purge rate exceed the development rate. If possible, purge wells at or below their recovery rates in order to minimize turbidity and drawdowns. The purge rate should not result in excessive drawdown. Excessive drawdowns can cause water to cascade into the well, resulting in a significant sample bias, excessive turbidity, and entrapment of air in the filter pack, which will cause long-term sample bias. When purging wells in shallow water tables, locate the pump intake near the top of the water table. Water will enter throughout the screen interval and move toward the pump, flushing all stagnant water from the borehole. If bailers are used, remove the water from the top of the water level. 4.5 Purging Low -Yielding Wells Monitoring wells incapable of yielding three saturated borehole volumes within 24 hours are considered low -yielding wells. Low -yielding wells may be pumped at or below their recovery rates or purged to practical dryness. Purging the well to practical dryness will evacuate the stagnant water in the borehole, but cascading water and exposing the filter pack to air may bias subsequent samples. Preferably, purge low -yielding wells at or below the recovery rate so that the saturated filter pack is not exposed to air. Purging at or below the recovery rate can take a considerable amount of time and may not be practical in some cases. Purge volume requirements and stabilization of field Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 9 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 parameters criteria cannot always be applied to low -yielding wells. However, you should still perform saturated borehole volume calculations and field parameter measurement. Purging low - yielding wells can be time-consuming. Identify low -yielding wells during well development so that careful planning and scheduling may be performed to increase efficiency in the field. Based on site - specific conditions and project objectives, evaluate whether to purge a well over an extended period of time or to purge it to dryness and collect a sample when there is sufficient recovery. Purging over time is preferred over dryness if at all practical. Development should provide enough site - specific information to allow the best method to purge a well to be assessed and to acquire representative samples before mobilizing to the field. 5.0 SAMPLING PROCEDURES This section gives the step-by-step procedures for collecting samples in the field. Record observations made during sample collection in the field notebook and field data sheet, as specified in Section 6 of this SOP. 5.1 Evacuating Well As stated previously, the purpose of well purging is to (1) remove stagnant water from the well and (2) obtain representative water samples from the geologic formation while minimizing disturbance to the collected samples. In most cases, purge the well three saturated borehole volumes and until field parameters stabilize. If the well has been pumped or bailed dry twice, it has been completely purged. Before purging a well, perform the following procedures: • Before evacuating or sampling, decontaminate all well probes, bailers, and other sampling devices as specified in SOP #1. Do not decontaminate dedicated downhole pumps. • Place clean plastic sheeting around the well. • Open the well and measure static water level following SOP #2. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 10 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 • Calculate the saturated borehole volume as specified in Section 4.2. • Calibrate field parameter measurement equipment as specified in SOP #9. • Obtain an initial sample from the bailer or purge pump for field measurements (e.g., temperature, conductivity, and pH measurements) and observation of water quality. • Begin purging three saturated borehole volumes of water with a bailer or pump. Take temperature, specific conductance, and pH measurements after evacuating each 1/4 to 1/2 (if practical) saturated borehole volume. Generally, pH values within ±0.1 pH unit and conductivity within ±10 percent throughout one saturated borehole volume indicate good stability of the water chemistry. If the chemistry is not stable, continue purging. • When evacuating a well using a pump, place the pump intake as follows: for low recovery wells (wells that pump dry at low rates), place the pump intake at the bottom of the screened interval for high recovery wells (wells that experience little drawdown with pumping), place the pump near the top of the water level to ensure the removal of stagnant water from the well bore. Purge the well at a rate that will not significantly draw down the well. • Bail or pump dry low -yielding wells during evacuation. If possible, let low - yielding wells recover before purging them dry again. If recovery is very slow, obtain samples as soon as sufficient water is available, but samples must be collected within 24 hours. 5.2 Obtaining Water Samples Ground water sample documentation, preservation, handling, packaging, and chain -of -custody procedures are specified in SOP #7. Collect ground water samples as follows: 1. Obtain samples for chemical analysis within two hours after purging is completed, if possible. For slow recovering wells, collect the sample immediately after a sufficient volume of water is available. Collect the water quality samples from within the well screen interval. 2. Assemble decontaminated sampling equipment. If bailers are used, use new nylon rope for each well for each sampling episode. Assemble the filtering apparatus. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 11 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 3. Make sure that sample labels have been filled out for each sample bottle as specified in SOP #7. 4. Place labels on bottle and tape over. 5. Lower the bailer slowly and gently into contact with the water in the well. Lower the bailer to the same depth in the well each time, within the screened interval. If submersible or bladder pumps are used to collect samples, reduce the discharge rate to about 100 milliliters per minute or as low as possible (Note: Some pumps may overheat at 100 milliliters per minute). Before collecting samples, pump the well at the reduced rate until the volume of water in the discharge hose has been purged. 6. Retrieve the bailer smoothly and empty the water in a slow, steady stream into the sample containers or direct the pump discharge into the sample containers. 7. Retrieve additional samples and slowly fill the sample bottles for all other analyses and QA/QC samples. Cap the sample bottles quickly. 8. Filter samples that require filtration with a disposable filter apparatus and peristaltic pump or electric submersible pump, as specified in SOP #7. 9. Slowly pour an unfiltered portion into the sample container for field parameter (e.g., pH, specific conductance, and temperature) analyses, perform the in -field analyses, and record the results. 1. Preserve samples as specified in SOP #7. 2. Place samples in baggies. 3. Place samples on ice in a cooler. 4. Record time of sampling. 5. Replace and lock well cap. 6. Complete field documentation and chain of custody record. 5.3 Field Quality Assurance/Quality Control Procedures and Samples Collect QA/QC samples during ground water sampling, as specified in the project planning documents. All QA/QC samples should be analyzed at the same time and in the same batches as the primary samples. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 12 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 QA/QC samples help identify potential sources of sample contamination and help evaluate potential error introduced by sample collection and handling. Label all field QA/QC samples with QA/QC identification numbers (i.e., "02" for duplicate samples, "03" for field blanks, "04" for rinsate samples, and "MS" for matrix spike samples) and send them to the laboratory with the other samples for analyses. Duplicate Samples To check for the natural sample variance and the consistency of field techniques and laboratory analysis, collect duplicate samples side -by -side with primary samples. For ground water sampling, collect a duplicate sample while collecting the primary sample. Fill the primary sample bottle(s) first and the duplicate sample bottle(s) for the same analysis second until all necessary sample bottles for both the primary and duplicate samples have been filled. Use different filter and tubing for the primary and duplicate samples. Handle the duplicate ground water sample in the same manner as the primary sample. Assign the duplicate sample the QA/QC identification number "02"; follow SOP #7 for documentation, preservation, handling, packaging, and chain -of -custody procedures; store the sample in an iced cooler; and ship it promptly to the laboratory so that analyses can be performed within required holding times. Collect one duplicate sample for every 20 primary samples collected so that a rate of at least 5 percent of primary samples collected is achieved. For example, if you collect from 1 to 20 primary samples during a sampling event, collect one duplicate sample, and if you collect from 21 to 40 primary samples during a sampling event, collect two duplicate QA/QC samples. Collect duplicate QA/QC samples so that they represent the time of collection, different sampling teams, field conditions, and sampling equipment variability. For example, if ambient conditions are altered that could impact sample quality, the QA/QC sampling frequency may be increased. Collect duplicate samples throughout the sampling event, not just at the end. Field Blanks Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 13 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 Collect field blanks by filling sample containers in the field with deionized water from the same source that is used for decontamination. Assign the sample the QA/QC identification number "03"; follow SOP #7 for documentation, preservation, handling, packaging, and chain -of -custody procedures; store the sample in an iced cooler; and ship it promptly to the laboratory so that analyses can be performed within required holding times. Collect one field blank sample for every 20 samples primary collected, so that a rate of at least 5 percent of primary samples collected is achieved. For example, if you collect from 1 to 20 primary samples during a sampling event, collect one field blank sample; and if you collect from 21 to 40 primary samples during a sampling event, collect two field blank samples. Rinsate Samples An equipment rinsate sample of sampling equipment is intended to be used to check if decontamination procedures have been effective. For the well sampling operation, collect a rinsate sample from the decontaminated sampling equipment (bailer or pump) and filter equipment before using it to obtain the sample. To collect a rinsate sample from a bailer, rinse deionized water over the decontaminated bailer and transfer it to the sample bottles. To collect a rinsate sample from an electric submersible pump, transfer the final deionized water rinse that is pumped through the discharge hose to sample bottles. The same parameters that will be analyzed in the ground water samples will be analyzed in the rinsate samples. Assign the rinsate sample the QA/QC sample identification number "04"; follow SOP #7 for documentation, preservation, handling, packaging, and chain -of -custody procedures; store the sample in an iced cooler; and ship it promptly to the laboratory so that analyses can be performed within required holding times. Collect one rinsate sample for every 20 primary water samples collected so that a rate for rinsate samples of at least 5 percent of primary samples collected is achieved. For example, if you collect from 1 to 20 primary samples during a sampling event, collect one rinsate blank sample, and if you collect from 21 to 40 samples during a sampling event, collect two rinsate blank samples. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop05 gw sampling.doc 14 January, 2( Ground Water Sample Collection Standard Operating Procedure #5 Collect rinsate blank samples so that they represent the time of collection, different sampling teams, field conditions, and sampling equipment variability. For example, if ambient conditions are altered that could impact sample quality, the QA/QC sampling frequency may be increased. Collect rinsate blank samples throughout the sampling event, not just at the end. Collect one rinsate blank sample for each type of sampling equipment used if less than 20 samples are collected (e.g., if 10 samples are collected by a bailer and 10 samples are collected by a submersible pump, you would collect two rinsate samples —one from the bailer and one from the pump). Matrix Spike Samples Matrix spike (MS) samples are required to evaluate potential matrix effects on sample analyses for all inorganic parameters. The laboratory will spike matrix spike samples for the inorganic parameters. Depending on the specific laboratory and sample volume collected, the matrix spike samples may be split from an existing sample or may require a separate sample. To samples that you collect specifically for matrix spike analysis, assign the QA/QC identification "MS"; follow SOP #7 for documentation, preservation, handling, packaging, and chain -of -custody procedures; store the sample in an iced cooler; and ship it promptly to the laboratory so that analyses can be performed within required holding times. The samplers will identify all samples selected for matrix spike split analysis on the Chain of Custody Form. Specify one matrix spike sample for each sample shipment group of 20 samples or less. Laboratory Replicate Depending on the laboratory conducting the analysis, laboratory replicate samples may be required. Laboratory replicate samples are split from the primary sample in the laboratory and analyzed as part of the laboratory's QA/QC program. The laboratory replicate does not require a separate sample volume. The sample that the laboratory splits must be identified by the samplers on the Chain of Custody Form. One laboratory replicate sample will be specified for each sample shipment group of 20 samples or less.

Divide sample identification numbers that are assigned into three fields, as shown in the following examples: Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 2 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 • Telesto1-01-01-011705 (primary sample at Telesto-01) • CCS-03-02-950318 (duplicate sample at Cottonwood Creek Station 03) • MW -01-3.5-4.0-01-960216 (primary sample at MW -01 from 3.5 to 4.0 feet). The first field (e.g., Telesto-01, CCS-03, or MW -01-3.5-4.0) uniquely identifies the specific sample and is usually tied to the location, matrix sampled, and/or specific sample depths. If required, any additional site -specific identification can be encoded within the sample location field. The second field identifies whether the sample is a primary (01), a field duplicate (02), field blank (03), equipment rinsate (04), or matrix spike (MS) sample. The third and final field contains the date in a day month year format to allow data in the analytical database to be sorted easily. For example, the first sample identified above was collected on January 17, 2005 4.2 Sample Labeling Label each sample that is collected in the field for future identification. Before collecting the sample, a member of the sampling team will fill out sample labels as completely as possible with black waterproof ink. In most cases, sample labels need to be obtained from the analytical company. Each label will contain at least the following information: • Sampler's company affiliation • Unique identification number • Date and time of sample collection • Analyses required • Method of preservation used • Sampler's signature. After the label is completed and attached to the sample container, place clear tape over the label to protect and secure it to the bottle. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 3 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 4.3 Sample Containers, Preservatives, Filtration, and Holding Times 4.3.1 Sample Containers Observe proper sample preparation practices (Section 4.5) to minimize sample contamination and potential repeat analyses due to anomalous analytical results. Before sampling, obtain commercially -cleaned sample containers from the analytical laboratory. Keep all documentation regarding sample bottle decontamination. Label the bottles as described in the Section 4.2. If sample bottles have not been pre -preserved from the laboratory, add preservatives in the field after sample collection. 4.3.2 Sample Preservation Samples are preserved to prevent or minimize chemical changes that could occur during transit and storage. Preservation methods include placing samples on ice and adding certain chemicals. If sample bottles are not pre -preserved, preserve samples immediately after collecting them to ensure that laboratory results are not compromised by improper coordination of preservation requirements and holding times. If sample bottles are pre -preserved, allow the sample to free fall into the container and do not allow it to overflow. Store samples on ice in coolers before and during shipping. Specific sample preservation requirements will be specified in the project work plan or sample plan and should be discussed with the laboratory before performing the sampling episode. Verify the proper pH of the sample after preservation. Use disposable pH test strips to quickly and conveniently verify proper preservation. Do not immerse the pH test strips directly into the sample bottle; instead, wet the strips with a small aliquot of the sample. 4.3.3 Sample Filtration Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 4 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 Filter samples that will be tested for dissolved cations and metals through a 0.45 -micron filter. Two common filtration methods use either disposable filter cartridges or disposable filters in a reusable filter holder. If possible, use disposable filter cartridges, because these will eliminate both decontamination and the possibility of cross -contamination. Attach the disposable filter cartridge to disposable silicon or Tygon® tubing and connect the combination to a peristaltic pump or directly to the electric submersible pump discharge. If reusable filter holders are used, be sure to decontaminate the filtration apparatus to avoid cross - contamination. Decontaminate filter holders as specified in SOP #1. Follow manufacturer's operating directions when operating filter holders and/or peristaltic pumps. Regardless of the filtration method used, flush the filter and tubing with at least 100 milliliters of sample water before collecting samples. An intermediate container may be required to hold the unfiltered sample. For the intermediate container, use a new, unused sample bottle or a container that has been decontaminated before use as specified in SOP #1. Filter samples that require chemical preservation before preserving them. 4.3.4 Sample Holding Times and Analyses Sample holding times are established to minimize chemical changes in a sample before analysis and/or extraction. A holding time is defined as the maximum allowable time between sample collection and analysis and/or extraction, based on the nature of the analyte of interest and chemical stability factors. Holding times will be specified in the project work plan or sample plan and should be discussed with the laboratory before performing the sampling episode. To minimize the possibility of exceeding holding times, send samples to the laboratory as soon as possible after collection by hand delivery or an overnight courier service. The chemical constituents, preservation, and holding times for samples will be summarized in the project work plan or sample plan. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 5 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 4.4 Sample Packaging for Shipping To maintain the required storage temperature, ship the samples by the quickest route. Do not allow travel time to exceed 24 hours. Inform the analyzing laboratory of the shipment and of the carrier handling the shipment. Ship the samples in a sealed, ice -filled cooler of good quality. Place the appropriate completed chain -of -custody (COC) forms in each cooler. The field sampling team shall pack non -hazardous samples for shipment as follows: 1. Obtain an appropriately sized cooler of good quality to pack the samples. 2. Line the cooler with a large plastic trash bag. 3. Place each sample bottle in a appropriately sized freezer zip -lock plastic bag, and place the bottle upright in the large plastic trash bag lining the cooler. 4. Double -bag ice in 1 -gallon freezer zip -lock plastic bags. Use enough ice to keep the samples cool until they are received by the laboratory. Use more ice in the summer time. 5. If required, use vermiculite or a similar absorbent material to fill voids in the cooler. 6. Verify that all samples in the cooler have been documented on the COC form. Record the number of the Federal Express Air Bill or other shipping record document on the COC form. Sign and date the COC form and retain a copy of it. Place the COC form in a 1 -gallon zip -lock plastic bag and tape the COC form to the inside lid of the shipping cooler. 7. Seal the plastic trash bag liner with a signed custody seal. This will maintain the chain -of -custody if the cooler is inadvertently opened during shipment. 8. Seal the cooler and drainhole with plastic or fiber tape. 9. Attach signed custody seals across two sides of the cooler top. 10. Attach an address label with the laboratory address and phone number and with a return address and phone number.

Attach a Federal Express Air Bill or another shipping document. Retain a copy of shipping documents with the COC form. 12. Notify the laboratory of the sample shipment. 13. Verify that the laboratory receives the samples and that the samples were received in good condition and were sufficiently cool. Transfer the samples in a timely fashion. Holding times and instructions for preservation for the parameters to be analyzed will be specified in the work plan. The laboratory must receive the samples as soon as possible to ensure that analysis and, if the need arises, re -analysis can be performed within the required holding time. Carefully evaluate samples collected at hazardous waste sites to determine if they should be classified as dangerous goods. If they are hazardous, contact the shipping company to determine the proper shipping procedure. In some cases, state department of transportation laws may apply and should be considered. 4.5 Sample Handling General sample handling procedures will include the following: • Always make field measurements on a separate sub -sample, not on the sample that is sent to the laboratory for analysis, and discard it after the measurements have been made. • Sample bottles shall be properly decontaminated if they are not certified clean by the manufacturer or have not been pre -preserved by the laboratory. • Do not use bottles that have been used in the laboratory to store concentrated reagents as sample bottles. • Do not allow the inner portion of sample containers and caps to come into contact with bare hands, gloves, or other objects. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 7 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 • If contact with air would change the concentration or characteristics of a constituent to be determined, secure the sample without contacting it with air and completely fill the container. • Keep sample containers in a clean environment away from dust, dirt, fumes, and grime. Keep vehicles clean to help eliminate contamination problems. • Field personnel shall wear disposable latex or nitril gloves when collecting samples. • Do not let foreign and metal objects contact acids and water samples. • Do not measure electrical conductivity on a sample that was first used to measure pH. Potassium chloride that diffuses from the pH probe can alter the conductivity of the sample. • Do not let samples stand in the sun. Store them in a cool place, preferably in ice chests with ice. • Ship samples to the laboratory without delay. 5.0 SAMPLE DOCUMENTATION AND CHAIN OF CUSTODY Documentation of the conditions and procedures used to collect, calibrate, treat, and handle samples and field data is one of the most important aspects of any monitoring program. Proper documentation provides sources to determine the integrity and applicability of the data. Carefully document all field activities in a logbook or on data sheets. Logbooks shall be bound with numbered pages and shall be written in with permanent black ink only. Record field activities in sufficient detail so that field activities can later be reconstructed from the notes. Any changes to the notes in the field book shall be made by drawing a single line through the incorrect material and initialing the markout. The following sections provide procedures and formats for documenting the field data and conditions at the time of sample collection, shipment to the laboratory, and laboratory analysis. While forms are provided to document specific tasks, the field sampling team shall maintain a field book for recording all other events, conditions, and observations during sampling. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 8 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 5.1 Field Notes Documentation of observations and data acquired in the field provide information on sample acquisition, field conditions at the time of sampling, and a permanent record of field activities. Record field observations and data collected during routine monitoring activities with waterproof ink in a permanently bound weatherproof field log book with consecutively numbered pages or on field data sheets. Field notebook and data sheet entries will include at least the following information. Consult relevant sampling and decontamination SOPs to supplement this list. • Project name • Location of sample • Sampler's printed name and signature • Data and time of sample collection • Sample identification numbers • Description of sample (matrix sampled) • Sample depth (if applicable) • Number and volume of samples • Sample methods, or reference to the appropriate SOP • Sample handling including filtration and preservation, as appropriate for separate sample aliquots • Field observations • Results of any field measurements, such as depth to water, pH, temperature, specific conductance • Personnel present Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 9 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 • Decontamination procedures. Strike out changes or deletions in the field book or on the data sheets with a single strike mark and be sure that the original information remains legible. Record enough information to allow the sampling event to be reconstructed from the notes alone. Completely fill out field data sheets and do not leave blank lines. Write "Not Applicable" or "NA" on blank lines. All field books will be signed daily by the person who made the entries. 5.2 Chain Of Custody Procedures The custody of all samples shall be documented on COC forms provided by the laboratory. The COC forms will document possession of the sample from collection through laboratory analysis. Follow appropriate sample custody and documentation procedures precisely to preserve sample integrity and to ensure the validity of field and laboratory data. As a result, all sample data will be traceable from the time and location of sample collection through chemical analyses and to the time when data are used. As described above, record initial information concerning sample collection in the field log book or on data sheets. Information on the custody, transfer, handling, and shipping of samples will be recorded on a Chain -of -Custody (COC) Form. The objective of the custody identification and control system for the samples is to ensure, to the extent practicable, that the following occur: • All samples scheduled for collection are uniquely identified. • The correct samples are analyzed and are traceable to their records. • Important sample characteristics are preserved. Telesto Solutions, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix asop07 samp handling.doc 10 January, 2005 Sample Documentation, Preservation, Handling, Packaging, and Chain ofCustody Procedures Standard Operating Procedure #7 • Samples are protected from loss or damage. • Any alteration of samples (e.g., filtration, preservation, and dilution) is documented. • A forensic record of sample integrity is established. • Legally traceable custody and possession records are maintained. For this project, a sample is defined as being in an individual's custody if the following conditions occur: • The sample is in that individual's actual physical possession. • The sample is in that individual's view after being in their physical possession. • The sample is in that individual's physical possession and then locked or otherwise sealed so that tampering will be evident. • The sample is maintained in a secure area that is restricted to authorized personnel only. General field custody procedures include the following: • As few people as possible should handle samples. • The field sampler is personally responsible for the care and custody of the samples collected until they are properly transferred. • When transferring the samples, the individuals relinquishing and receiving the samples will document the transfer by signing, dating, and writing the time of the transfer on the COC form. • The person responsible for delivering the samples to the laboratory or to the shipping carrier will sign the COC form, retain the third copy of the form, document the method of shipment, and send the original and the second copy of the form with the samples. Upon arrival at the laboratory, the person receiving the samples will sign the COC form and return the second copy to the Project Manager. • Custody seals must be attached so that it is necessary to break the seal to open the shipping container. The person affixing the custody seal will sign and date the seal.

This SOP describes the equipment and field procedures necessary to measure field parameters. Whenever water samples are collected, measure field parameters on a separate aliquot of the sample immediately after collecting the sample. This SOP describes how to properly calibrate instruments and measure pH, temperature, conductivity, and turbidity in the field. Many types of meters and methods are used to measure field parameters. The following sections: (1) list specific equipment requirements, (2) clarify the objectives of measuring field parameters to help the samplers obtain the proper equipment, and (3) describe the required apparatus for performing the measurements. 2.0 RELATED STANDARD OPERATING PROCEDURES This procedure is intended to be used with the following SOPs: SOP # Title 1 Equipment Decontamination 3.0 pH METER CALIBRATION AND MEASUREMENT 3.1 Required pH Measurement Equipment Use the following apparatus and supplies for measuring pH in the field: • Portable Hach One pH Meter Model 43800-00 with Hach One Combination pH Electrode Model 48600 or the EC10 Portable pH/mV/Temperature Meter Model 50050 with the Combination pH Electrode with Temperature (Gel -filled) Model 50200 • Spare electrolyte cartridge, if required Shepherd Miller, Inc. r:Iweldcountyldunnpit hmlproductslbaselinestudieslgroundwaterlappendixdlappendixa_sop09 inst calib and measurement.doc1 Januaty 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 • Hach pH Electrode Storage Solution, Catalog No. 50301-49 • Extra batteries • Beakers • Buffer solutions of pH 4, 7, and 10 • Deionized or distilled water and wash bottle • Kimwipes or equivalent. Many chemical reactions are pH -dependent; therefore, pH is an important indicator of the state of the water. If possible, determine the pH in situ; if this is not possible, determine the pH from a water sample as soon as possible. Determine the pH by the electrometric method using standard buffer solutions. The electrometric method is the preferred method because of its greater accuracy and ease of measurement. A combination electrode, which combines the glass membrane electrode and the reference electrode, may also be used. Many portable battery -powered pH meters are available with a variety of features and abilities. The meter selected for field use should be rugged and it should be carried and stored in a foam -lined, water-resistant carrying case. The carrying case should have sufficient room to store extra pH buffers, electrode filling solution, spare electrodes, cables, and batteries. Meters recommended should automatically compensate for temperature and be capable of calibration with a two -point (two buffers) slope adjustment method. The meter should have a precision of +0.05 units. 3.2 pH Meter Calibration Procedures Before collecting samples, calibrate the pH meter in accordance with the manufacturer's instructions using calibration solutions. The field sampling team shall record all pH measurement data, including calibration dates, readings, SMI meter number, and temperatures, on a data sheet or in a Shepherd Miller, Inc. r:lweldcountyldunnpit hmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop09 inst calib and measurement.doc2 January 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 field notebook. The field sampling team shall be familiar with the meter and shall follow the manufacturer's instructions for calibrating and using the meter. Appendix A presents the manufacturer's manual for the Portable Hach One pH Meter Model 43800-00, Hach One Combination pH Electrode Model 48600, the EC10 Portable pH/mV/Temperature Meter Model 50050, and the Combination pH Electrode with Temperature (Gel -filled) Model 50200. Calibrate the pH meter at the start of each sampling day and, as needed, when measuring waters with different pH values. Thoroughly document all calibrations, including the buffer readings and temperatures in the field book or data sheets. The field sampling team shall do the following when calibrating the meter according to the manufacturer's procedures: • Condition new pH electrodes by soaking them for one hour in Hach pH Electrode Storage Solution. Do not condition pH electrodes that have been properly stored in Hach pH Electrode Storage Solution. • One of the buffer solutions used for the slope adjustment should bracket the anticipated pH of the sample, and the other buffer should always have a pH of 7. Ensure that the buffer solutions are at the same temperature and are as close as practical to the temperature of the water to be measured. Use buffer solutions once and then discarded them. • Before immersing the probe into the buffer or sample, rinse the probe with deionized or distilled water and blot it dry with a clean wipe. Protect the glass tip of the probe from abrasion and scratching. • Adjust the slope of the meter with two buffer solutions (2 -point slope adjustment) at least daily, and preferably twice per day to account for changes in conditions of the probe and meter and, as needed, when measuring waters with different pH values. • If the slope deviates significantly from its theoretical value, search for a potentially defective electrode or contaminated buffer solution. Shepherd Miller, Inc. r:lweldcountyldunnpit hmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop09 inst calib and measurement.doc3 January 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 3.3 pH Measurement The sampler shall measure pH in the field as follows: 1. Thoroughly check the pH meter, including the battery, and then calibrate the meter in the laboratory before taking it to the field. The buffers used for calibration should bracket the anticipated pH values to be measured. 2. Recalibrate the meter in the field before use. 3. If the pH is measured in a container, rinse the sample container with deionized water and then rinse it three times with the sample water prior to measurement. Rinse the pH probe with deionized water and, if possible, blot the probe dry with a clean wipe. Be sure to protect the fragile glass bulb at the end of the probe from damage. 4. Immerse the electrode into the water, allow the pH reading to stabilize, and monitor the drift of the instrument. Do not immerse the electrode above the top of the pH probe. When the pH reading stabilizes, record the temperature and the pH reading to the nearest 0.01 unit. 5. Between measurements, store the electrode in pH Electrode Storage Solution. 6. Measure samples within a short period of time after sampling and on a separate aliquot of the sample. 7. For the Hach One Combination pH Electrode Model 48600, dispense electrolyte if the reading becomes unstable, erratic, or if stabilization takes too long. An unstable reading may also indicate an air bubble in the reference line. Depress the dispenser button repeatedly until the bubble is expelled (5 to 10 clicks should be sufficient). Note that it is not necessary to refresh the electrolyte gel at the reference outlet between readings unless the reading is not stable. 8. Short-term electrode storage (between measurements/up to one week) will be in the Hach pH Electrode Storage Solution or cotton soaked in the Hach pH Electrode Storage Solution. Do not store in deionized water, as this will shorten the electrode life. 4.0 CONDUCTIVITY METER CALIBRATION AND MEASUREMENT Electrical conductivity, or specific conductance, is the ability of water to conduct an electric current and depends on the concentration of ions in solution. The relationship between conductivity and the concentration of dissolved solids is approximately linear for most natural waters. Changes in this Shepherd Miller, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop09 inst calib and measurement.doc4 January 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 relationship indicate changes in the proportions of different salts and, therefore, changes in the sources of dissolved substances that enter the water body. Conductivity is usually measured in the field with a hand-held meter that is equipped with a conductivity cell and temperature probe. The meter measures the ability of water to conduct electricity across a specified distance and cross-sectional area. Numerous types of conductivity meters are available with various features and accessories. For measuring conductivity in the field, use a meter that can also measure temperature, has either a manual or automatic temperature compensator, and that displays conductivity directly in units of microsiemens per centimeter (µS/cm), corrected to a temperature of 25 degrees Centigrade (°C). Carry and store the meter in a foam -lined, water-resistant carrying case. The carrying case should have sufficient room to store extra calibration solution, spare probes, and batteries. 4.1 Conductivity Measurement Equipment Use the following apparatus and supplies for measuring conductivity in the field: • Hach CO150 Conductivity Meter Model 50150, Hach Conductivity/TDS Meter Model 44600, or Oakton® WD -35607-10 Hand -Held Conductivity Meter • Extra battery • Calibration solutions which bracket expected range of measurements • Deionized water • Wash bottle • Kimwipes • Beakers. 4.2 Conductivity Meter Calibration Shepherd Miller, Inc. r:lweldcountyldunnpit hmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop09 inst calib and measurement.doc5 January 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 Before collecting samples, calibrate the conductivity meter using calibration solutions in accordance with the manufacturer's instructions (Appendix B). The sampler shall record all conductivity measurement data, including calibration dates, readings, SMI meter number, and temperatures, on a data sheet or in a field notebook. Reagent -grade potassium chloride (KC1) or other equivalent solutions are universally used as reference solutions to calibrate conductivity (specific conductance) equipment. The reference solutions are also used to check the accuracy of the meter, usually on a daily basis or, as necessary, at more frequent intervals. The conductivity of the reference solutions that are used to calibrate the meter should bracket the expected range of the conductivity of the water samples. Commercially prepared calibration standards are available from laboratory suppliers at many standard concentrations. The sampler shall calibrate the meter as follows: 1. Calibrate the meter according to the manufacturer's instructions. 2. Prepare or obtain standard reference solutions of a known value at a known temperature. Adjust the meter or the calibration solution to the correct temperature. 3. Adjust the meter to read the reference conductivity. Rinse the probe with deionized water and blot the probe dry. Re -immerse the probe in the reference solution and read the measured value to validate the corrected conductivity. 4.3 Conductivity Measurement Whenever possible, measure conductivity in situ or immediately after a sample is collected. If conductivity is measured within 24 hours, do not filter the conductivity sample beforehand. Record conductivity readings to the nearest 0.1 µS/cm, corrected to 25°C . The sampler shall measure conductivity as follows: Shepherd Miller, Inc. r:lweldcountyldunnpit hmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop09 inst calib and measurement.doc6 January 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 1. Check the meter, including the battery, and calibrate the meter before taking it to the field. Buffer solutions used for calibration should bracket the expected conductivity values to be measured. 2. Recalibrate the meter in the field before use. 3. Rinse the probe with deionized water and blot the probe dry with a clean wipe, without wiping the plating on the cell. 4. Insert the probe into the sample solution. Immerse the tip to or beyond the vent holes and agitate the probe vertically. Make sure that air bubbles are not trapped near the temperature sensor. Allow the reading to stabilize before recording measurements. Measure and record the temperature of the sample. 5. During normal use, rinse the probe thoroughly with deionized water between measurements to minimize the buildup of interfering substances on the probe element. 6. Because the Model 44600 Conductivity Meter does not automatically turn itself off, verify that the unit is off before storing it. 5.0 TURBIDITY METER CALIBRATION AND MEASUREMENT One of the most sensitive and, therefore, the most representative field parameter measured during ground water sample collection is turbidity. Measure turbidity in the field with the Hach Portable Turbidimeter Model 2100P. The Hach Portable Turbidimeter Model 2100P manual is presented in Appendix C. 5.1 Turbidity Measurement Equipment Use the following apparatus and supplies for measuring turbidity in the field: • Hach Portable Turbidimeter Model 2100P • Extra battery • Calibration solutions which bracket expected range of measurements • Silicone oil • Deionized water Shepherd Miller, Inc. r:lweldcountyldunnpit lrmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop09 inst calib and measurement.doc7 January 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 • Wash bottle • Liquinox solution • Kimwipes • Beakers. 5.2 Turbidity Meter Calibration and Measurements Calibrate the turbidimeter before mobilizing to the field. Once in the field, check the calibration by measuring standards of known turbidity as specified in the calibration and measurement procedures presented in Appendix C. The field sampling team shall record calibration checks, dates, and the SMI meter number on a field data sheet or in the field book. Note the following operational considerations: • Avoid prolonged exposure to ultraviolet light and sunlight. • Do not hold the instrument during measurements; place the instrument on a flat, steady surface. • Measure samples immediately to prevent temperature changes and settling. Avoid sample dilution when possible. Particles suspended in the original sample may dissolve or otherwise change characteristics when the sample temperature changes or when the sample is diluted, resulting in a non -representative sample measurement. • Handle measurement cells only by the top to minimize dirt, scratches, and fingerprints in the light path. • Always cap the sample cell to prevent spillage of sample into the instrument. • Always close the sample compartment lid during measurement and storage. • When oiling the sample cells, use only a thin coat of oil. Do not use excessive amounts of oil. The sampler shall measure turbidity as follows: Shepherd Miller, Inc. r:lweldcountyldunnpit hmlproductslbaselinestudieslgroundwaterlappendixdlappendix a sop09 inst calib and measurement.doc8 January 2005 FieldParameterInstrument Calibration and Measurement Standard Operating Procedure #9 1. Thoroughly check the meter, including the battery, and then calibrate the meter in the laboratory before taking it to the field. 2. Measure the turbidity of the standard and compare it to its certified value. 3. Clean the sample cell. 4. Fill the sample cell with sample. 5. Clean and oil the sample cell. 6. Place the cell in the meter. 7. Select the range. 8. Signal average the sample (if necessary). 9. Read and record the turbidity to 0.01, 0.1, or 1.0 NTU, depending on the range of the sample. 1. Empty and clean the sample cell.
