PFH C-1 Windsor East Mine, Exhibit D — Mining Plan September 2022 1.0 GENERAL The Windsor East Mine property is located within the Town of Windsor in Weld County, Colorado. The Windsor East Mine site is on land owned by GWIP, LLC (GWIP). Martin Marietta Materials (Martin Marietta) has a lease to mine the GWIP property. The leased area is located within Parcel 08073600021, in Section 35 and 36, Township 6 North, Range 67 West of the 6. Prime Meridian. The geographic coordinates for the main entrance area are 40.450040° N, -104.851359° W. The property contains a significant commercial deposit of sand and gravel that is associated with the Cache la Poudre River. While the property is owned by GWIP, LLC, the mineral rights in the affected area are owned by the Colorado State Board of Land Commissioners. The Windsor East Mine is 150.3 acres. The permit boundary and affected area are the same for this application. Within the site, 90.1 acres of the land will be mined, and the remaining unmined acres will be used for overburden and topsoil stockpiles, offsets from existing structures and property lines. The permit boundary for the site was established to avoid impacting the riparian area along the Cache la Poudre River. In addition, all mining excavations will be set back a minimum of 200' from the riverbank and then backfilled to be no closer than 400' from the riverbank. Riverbank locations were located using GPS in June 2022 and the locations may vary over time. Offset distances are in accordance with the Technical Review Guidelines for Gravel Mining and Water Storage Activities, published by the Mile High Flood District in January 2013. A wetland area was identified on the site and mapped. The US Army Corps of Engineers has determined that this is non jurisdictional. Please see Exhibit J-1 for the documentation. The proposed mining plan shows that Martin Marietta will mine through this area. There were oil and gas wells and flowlines through the middle of the property that were owned by Noble and DCP Midstream that are no longer used. Most of the wells have been plugged and abandoned per COGCC requirements. There is only one well left (State 8-36) for DCP to complete abandonment and the 150' radius will be maintained until the abandonment is complete. Martin Marietta has contacted DCP Midstream and found out that all the flowlines were properly abandoned in place and Martin Marietta can remove them as they mine. Martin Marietta will contact DCP Midstream as they encounter and remove these lines so that DCP can appropriately document their removal. There is also an oil and gas flowline running north and south along the east edge of the property. Martin Marietta is working with DCP Midstream to determine what needs to be done to cross this line with conveyor and equipment. It is estimated that the overburden will amount to approximately 676,000 cubic yards. Overburden exists to an average depth of approximately 5 feet over the entire site. All overburden and clay needed for the construction of the final reclamation will come from this site. The average depth of sand and gravel is 10 feet across the site and mining at the site is intended to progress down to bedrock. Deere & Ault Consultants, Inc. drilled 8 borings in 2017 for the property owner and Martin Marietta drilled 16 borings across the site in December 2019 with similar results. The results of these borings were used to understand the subsurface conditions across the Windsor East Mine area. Drilling logs indicate the general subsurface profile consists of approximately 3 to 9 feet of silty to clayey sand overburden, overlying approximately 6 to 17 feet of well graded gravel with varying amounts of sand and silt, overlying claystone bedrock. Groundwater was encountered at depths ranging from 4 to 7 feet in the most recent 2019 Martin Marietta borings. There is evidence that dewatering from the Parsons Mine to the east has increased the depth of the water table to 11-12 feet below the surface. The site will be mined in four phases, called out on the Exhibit C Mining Plan map as Cells A, B, C and D. These phases are neither representative of the maximum area of disturbance nor do they limit disturbance to a particular phase. TETRA TECH Page 114 Windsor East Mine, Exhibit D — Mining Plan September 2022 Agricultural, industrial, residential, and mining uses surround the property. 2.0 METHODS OF MINING The typical mining procedure for all phases will be as follows. Any areas slated for protection will be identified in the field to assure that mining operations will be set back as appropriate. The topsoil and overburden will be stripped with scrapers and stockpiled in the designated stockpile areas identified in Exhibit C. Overburden found on the site will also be used to fill in the reclamation slopes. Overburden and topsoil reserved for reclamation will be vegetated and stabilized in accordance with Rule 3.1.9(1). Prior to mining, a dewatering trench will be constructed around the perimeter of each phase. A sump hole will be created at the lowest point of each dewatering trench. The sump holes and dewatering trenches will allow sediment to settle before the water is pumped to the Cache la Poudre River using a dewatering pump in accordance with Colorado/NPDES discharge permit regulations. Pipes will be used to transport the water from the mine to the Cache la Poudre River. The location of the discharge pipes will be adjusted throughout the mining process. When the mined alluvium is sufficiently dry, front-end loaders will excavate the material. The high wall of the mine cells will not exceed a 1:1 slope. All mined material will be deposited on conveyors which will transport the material to Martin Marietta's existing plant site at the Parsons Mine (M-2009-082), directly east of Windsor East. No materials processing will occur at the Windsor East Mine site. Surface water within the mine areas will drain internally. Direct precipitation falling on a mine cell is collected in the perimeter dewatering trench and pumped out. There will not be any uncontrolled releases of surface water and sediment from mining areas. Storm water collected in the open mine will be managed in accordance with Colorado/NPDES discharge permit requirements. Water rights associated with the site will be used for dust control operations along the roads, stockpiles, transport of material and berms. The water balance discussed in Exhibit G estimates the gallons per week necessary to limit dust emissions. The water will be supplied using a 2,500 -gallon water truck. No explosives will be used to mine the site. 3.0 OVERBURDEN Topsoil and overburden will be stripped with scrapers or a dozer and placed separately in temporary stockpiles within the permit area limits. The topsoil will be segregated and stored separately from the overburden material as required by Rule 3.1.9(1). The stockpiles will have an average height of 8 feet tall; they will have maximum 3:1 (horizontal:vertical) side slopes. The topsoil stockpiles will be protected from wind and water erosion by vegetative cover (see the Seed Mix for Upland Areas found in Exhibit E). The stockpiles will be broadcast seeded and incorporated into the weed control program. Weed control consists of chemical treatments as needed in the applicable fall and spring seasons. Topsoil and overburden stockpiles reserved for reclamation will be vegetated and stabilized in accordance with Rule 3.1.9(1). The overburden stockpiles will be continuously rotating. Initially, a portion of a phase will be stripped, and the overburden stockpiled temporarily within the permit boundaries. Once the deposit has been mined from the stripped portion, the temporary stockpile will be removed and used for reclamation. The remaining portion of the cell will then be stripped, and the overburden will be stockpiled on the mine floor or placed immediately in the reclamation slope. No excess overburden is anticipated for this site. 4.0 COMMODITIES TO BE MINED The primary commodity to be mined will be aggregate and a secondary commodity will be gold. Martin Marietta will supply local, county, and state governments, as well as private industry with aggregate from this facility. If gold is mined it will be used for commercial purposes. OTETRA TECH Page 2(4 Windsor East Mine, Exhibit D — Mining Plan September 2022 5.0 OFFSETS Tetra Tech prepared a Slope Stability Analysis to ensure that all existing structures will be protected based on the proposed reclamation slopes. 6.0 ROADS AND CONVEYORS Preparation for mining for each phase will include a 15' wide gravel access road around the perimeter of the cell. Any additional short-term haul access will be constructed with 6" of native sand and gravel from the floor of the mine. These gravel roads will be removed and reclaimed as mining and reclamation is completed for each phase. These areas have been included in the permitted acreage. All the material will be transported via conveyor from the mining cells to Martin Marietta's Parsons Mine to the east for processing. The conveyor is set on concrete block or frames. The main line will run down the future Crossroads path and feeders will be dropped in to each phase we are mining and then removed before reclamation. All areas affected by the conveyors will be re-topsoiled and seeded to restore ground to the original condition. A 10.5' wide existing road that currently connects to WCR 23 will be utilized to provide street access to this site. The location of this existing road is shown on Exhibit C, Pre -Mining Plan. It is located northwest of cell B. 7.0 MINE SCHEDULE Depending on market conditions, the Windsor East Mine operation will process approximately 450,000 - 500,000 tons of aggregate per year. At this rate, Martin Marietta anticipates mining and reclaiming the site in approximately 8 years (about 6 years to mine and another 2 years to complete reclamation and get grasses to establish). The table outlines the anticipated mine schedule by phase. As previously stated, this schedule is just an estimate since the rate of mining and overall life of the mine is dependent upon demand and market conditions. Phase Mine Area (in acres) Projected Time to Mine (in years) Cell A 35.3 2± Cell B 17.7 1± Cell C 32.3 2± Cell D 4.8 1± 8.0 PHASE OVERVIEW The four cells in Windsor East will be mined as explained below. The following is a detailed description of Martin Marietta's plan to mine the four cells that are proposed along with an explanation of how the topsoil and overburden will be handled. Please refer to Exhibit C-3 for the locations of each mining cell, topsoil stockpile (TS#) and overburden stockpile (OB#). 1. The topsoil from Cell A will be stripped and placed on the north property line in stockpile TS1. Overburden from Cell A will be stockpiled in O81. 2. Cell A will then be mined. 3. Topsoil from Cells B and C will be stripped and placed in stockpiles TS1, TS2, and TS3. Overburden from Cell B will remain in place and overburden from Cell C will be used to reclaim the slopes of Cell A. Any OTETRA TECH Page 314 Windsor East Mine, Exhibit D — Mining Plan September 2022 excess overburden from Cell B will be placed in stockpile OB1 or in the overburden overflow area on top of Cell B. 4. Cell C will be the second cell mined. The slopes of Cell C will be concurrently reclaimed using overburden from stockpiles OB1 and the overburden overflow area on top of Cell B. 5. Cell D topsoil will be stripped and used in reclamation of Cells A and C. Overburden from Cell D will be used in the reclamation of Cell C. Any excess overburden from Cell D will be placed in stockpile 0B2. 6. Cell D will then be mined. It will then be reclaimed by backfilling it with overburden from the overburden overflow area on top of Cell B including the overburden originally left behind in Cell B. 7. Cell B will be the last cell mined, and it will be backfilled with the remaining overburden from stockpile OB1. 8. The topsoil from TS1, TS2 and TS3 will then be used to complete reclamation of Cells B and C as well as the edges of Cells A and C. 9.0 EARTHMOVING Earthmoving is performed using a combination of mobile mining equipment including, but not limited to loaders, dozers, scrapers, backhoes, water trucks, diesel powered generators, and pumps. TETRA TECH Page 414 Windsor East Mine, Exhibit E — Reclamation Plan September 2022 EXHIBIT E - RECLAMATION PLAN 1.0 DESIGN INTENT This site will be mined and reclaimed to create two water storage ponds that the landowner, GWIP will own and use for water storage. Water stored in the ponds will be used by GWIP to satisfy augmentation requirements. Currently, GWIP leases water from the Town of Windsor to satisfy some augmentation requirements. So, upon completion of the reservoirs, GWIP will no longer need to lease water from Windsor to meet this requirement. Two lined water storage reservoirs surrounded by revegetated upland areas will be created by the mining and reclamation process. Native and adaptive plantings and ground covers will be used to restore and enhance all areas disturbed by mining activities that will not be within a lined water storage cell. This reclamation plan was developed based on: A thorough evaluation of the environmental resources and existing conditions on and adjacent to the property; • The context of the property relative to existing and planned land uses in the area; • The volume, depth and configuration of the mineral resource; • The landowners' plans for the property; and • The rules and policies of Windsor, the Colorado Division of Mining, Reclamation and Safety and other applicable local, State and Federal agencies. Key considerations include the following: The permit boundary on the south was placed outside of the Cache la Poudre riparian corridor to protect the area. The 200' setback from the river will be clearly marked in the field and best management practices will be used as necessary to implement the CDPHE Storm Water Management Plan for the site. Maintenance activities on the site will also include a comprehensive Weed Management Plan (see attached) to limit the spread of invasive species into the riparian areas and wetlands. Much needed water storage reservoirs will be created on the site. The reservoirs will be lined with compacted material acceptable to construct liners that are found on the site. Five groundwater monitoring wells have been installed to establish pre -mining baseline water levels along with the Parsons Mine (M-2009-082) monitoring wells. The wells will be used to monitor effects from mining and provide information for mitigation of potential impacts on groundwater levels and riparian vegetation, as necessary. If levels drop below seasonal levels, dewatering water will be diverted to the areas to sustain existing vegetation to limit impacts during mining. Details of the monitoring and mitigation plans are provided in Exhibit G. 2.0 POST -MINING LAND USE The post -mining land use, as proposed in this Reclamation Plan consists of water storage ponds surrounded by upland vegetation. All disturbed areas will be vegetated as appropriate with a native seed mix, as recommended by the Soil Conservation Service (recommended seed mixes below). These uses are compatible with the surrounding land uses and with the Town of Windsor planning goals. OTETRA TECH Page 114 Windsor East Mine, Exhibit E — Reclamation Plan September 2022 Martin Marietta will concurrently mine and reclaim this site. Reclamation, including regrading and seeding, will be completed within two to five years following the completion of mining or filling operations for each phase. The mining and reclamation will leave no high walls on the property. No acid forming or toxic materials will be used or encountered in the mining. There will be no auger holes, adits, or shafts. 3.0 RECLAMATION MEASURES - MATERIAL HANDLING Site reclamation measures are illustrated in Exhibit F. Reclamation of the site will include 2 water storage ponds (54.7 acres) and 95.6 acres of upland vegetation. The ponds will be reclaimed as water storage ponds. All mine walls will be re -graded with overburden material to create a compacted liner. Slopes above the post -mine high water level will be 3:1 and slopes below the post -mine high water level will not exceed 3:1. Topsoil will be spread to a minimum depth of 6" over the surface of all areas outside the water storage basins that are to be revegetated as uplands. Scrapers will be used to place the backfilled material. Using scrapers to layer the lifts at a maximum 3:1 slope ensures a stable configuration. Reclamation quantities and costs are summarized in Exhibit L. 4.0 WATER Overburden and mine materials will be inert and impacts to local surface water or groundwater quality are not anticipated to occur because of mining activities. Martin Marietta Materials, Inc. will comply with all applicable Colorado water laws and all applicable Federal and State water quality laws and regulations and appropriate storm water management and erosion control to protect the adjacent Cache la Poudre River and riparian vegetation. Cell B will be backfilled above the water table leaving a 5 -foot depression as defined in our lease. No stormwater will be directed to this depression, but any stormwater collected will dissipate into the ground. GWIP, LLC, the landowner, intends to use this depression as part of their stormwater detention when they develop on adjacent land and will work with Town of Windsor on their development once our reclamation permit is released. Martin Marietta is not required to install any structures as part of the depression including but not limited to headwalls, outlets, piping and forebays. 5.0 WILDLIFE Presently, the area is used for general agriculture. There is significant habitat for many wildlife species along the river corridor which is outside our permit boundary. Please see Exhibit H (Wildlife Information) for more information pertaining to the recommendations and conclusions from the environmental report. 6.0 TOPSOILING Topsoils in the proposed mine areas are predominantly Aquoll and Aquents, Ellicott, Colombo clay loam, Kim loam, and Nunn clay loam. All suitable soil material will be salvaged for topsoil replacement. Topsoil will be replaced, where required, in reclaimed areas at a depth of a minimum of 6 inches. The topsoil will be segregated and stored separately from the overburden material as required by Rule 3.1.9(1). Sufficient topsoil will be stockpiled within each phase to reclaim all disturbed areas. The mine plan map depicts the location and configuration of the berms. The berms will be protected from wind and water erosion by vegetative cover if in place for more than 180 days and will be vegetated depending on the seeding "window" parameters for dryland grass, which are typically between September and April. Soil amendments are not expected to be required due to the nature of the soils. However, topsoil samples will be subjected to agricultural testing prior to reclamation to assess fertilizer requirements. The Soil Conservation QTETRA TECH Page 214 Windsor East Mine, Exhibit E — Reclamation Plan September 2022 Services (SCS) will be contacted periodically throughout reclamation for soil tests. SCS soil fertilizer recommendations, if any, will be followed. 7.0 REVEGETATION Following topsoil replacement, reseeding will be performed according to SCS recommended practices. Based on SCS guidance for other local projects having similar surficial soils, the following revegetation procedures are anticipated • Grass seed will typically be planted in unfrozen soil between October 1 and April 30. • Grass seed will be planted with a grass drill, or where necessary, with a broadcast seeder. • The proposed seed mix and application rates in pounds of pure live seed per acre are described on the following pages. • Weed control practices will be implemented as required. The above procedures may be modified as conditions dictate. If a significant invasion of noxious weeds occurs, the area will be mowed periodically for control. Weeds will be mowed before they go to seed during the first growing season. Mechanical control will be used as a first priority. Chemical methods will be used only if no other alternative produces acceptable results. 8.0 WEED MANAGEMENT PLAN A weed management program will be undertaken to control noxious and invasive plant species and to replace those species with native and naturalized vegetation. Canada thistle (Cirsium arvense) and leafy spurge (Euphorbia esula) will be treated by a combination of mowing at regular intervals and herbicides used at the appropriate times and applications levels.

The information in this Section is intended to satisfy the requirements outlined in Sections 3.1.6, 6.3.3, 6.3.4, and 6.4.7 of the Colorado Mined Land Reclamation Board's Construction Material Rules and Regulations. Section 3.1.6 (1) Hydrology and Water Quality: Disturbances to the prevailing hydrologic balance of the affected land and of the surrounding area and to the quantity or quality of water in outface and groundwater systems both during and after the mining operation and during reclamation shall be minimized by measures, including, but not limited to: (a) compliance with applicable Colorado water laws and regulations governing injury to existing water rights; (b) compliance with applicable federal and Colorado water quality laws and regulations, including statewide water quality standards and site -specific classifications and standards adopted by the Water Quality Control Commission; (c) compliance with applicable federal and Colorado dredge and fill requirements; and (d) removing temporary or large siltation structures from drainage ways after disturbed areas are revegetated and stabilized, if required by the Reclamation Plan. Section 6.4.7 (1) If the operation is not expected to directly affect surface or groundwater systems, a statement of that expectation shall be submitted. This site is directly adjacent to the Cache la Poudre River. The Cache la Poudre River will be utilized for the discharge of dewatering water from each of the proposed mine cells. The presence of the river has the collateral benefit of mitigating groundwater drawdowns and associated impacts to wells east of the Site. (2) If the operation is expected to directly affect surface or groundwater systems, the Operator/Applicant shall: (a) Locate on the map (in Exhibit C) tributary water courses, wells, springs, stock water ponds, reservoirs, and ditches on the affected land and on adjacent lands where such structures maybe affected by the proposed mining operations. Please see Exhibit C Pre -Mining Maps for the location of all tributary water courses, wells, springs, stock water ponds, reservoirs, and ditches on the affected land and on adjacent lands where such structures may be affected by the proposed mining operations (b) Identify all known aquifers OTETRA TECH Page 1(11 Windsor East Mine, Exhibit G — Water Information September 2022 The Windsor East site is underlain by two aquifers: • The valley -fill deposits of the Lower Cache la Poudre River. o described in: Hershey, L.A . and PA. Schneider, 1972. "Geologic Map of the Lower Cache la Poudre River Basin, North-Central. Colorado", USGS Miscellaneous Geologic Investigations Map 1-687. (See Figure G-2) The Fox Hills Sandstone o described in: Robson, S.G. 1989, "Alluvial and Bedrock Aquifers of the Denver basin — Eastern Colorado's Dual Ground -Water Resource", USGS Water -Supply Paper 2302 (c) Submit a brief statement or plan showing how water from de -watering operations or from runoff from disturbed areas, piled material and operating surfaces will be managed to protect against pollution of either surface or groundwater (and, where applicable, control pollution in a manner that is consistent with water quality discharge permits), both during and after the operation. The geologic conceptual model of the subsurface and groundwater was developed from the geologic map for the area and the boring logs associated with the installation of the monitoring well network at the Windsor East site and the Parsons Mine site located to the east (Figure G-3). Based on water levels measured in these wells, a groundwater level elevation map was developed (Figure G-5). Following removal and stockpiling of topsoil, each of the four cells will be dewatered and mined. Sand and gravel will be extracted using the "dry" mining method in which the water table is lowered to allow mining to be performed under drained conditions. To lower the water table, local dewatering is conducted using a perimeter drain constructed around each planned mining cell. The dewatering system would discharge to the Cache la Poudre River. Dewatering of the mine would lower the groundwater levels to a limited extent in the surrounding alluvial aquifer and will not impact the underlying Fox Hills Sandstone aquifer. Effects on groundwater levels are projected to be limited in extent due to natural and manmade hydrologic and hydrogeologic characteristics and boundaries, principally including the transmissive nature of the alluvial aquifer, the Cache la Poudre River, and the mining operation. Figure G-6 illustrates resulting changes to groundwater flow directions during mining and after reclamation. The available gravel resource is anticipated to be mined for approximately 6 years; however, the rate of mining and overall life of the mine is dependent upon demand and market conditions. All material mined at Windsor East will be conveyed to Martin Marietta's adjacent Parsons Mine site for processing at the existing plant on that site. Upon completion of mining, the reclamation plan for the mine includes the emplacement of compacted clay embankment liners in Mining cells A and C, while cells B and D will be backfilled. These cells will thereby be converted to sealed water storage reservoirs, which will be owned and used by GWIP, LLC, the landowner of the Windsor East Mine site. Exhibit D: Pre -Mining and Mining Plan shows the location of the Affected Area and proposed mining cells. Changes to the hydrologic balance within the Affected Area will be limited to the localized dewatering associated with the excavation of the mine cells, and the minor alteration of the existing groundwater flow patterns due to the subsequent installation of compacted clay embankment liners during reclamation. Figures G-5 and G-6 show the mine cells and conceptual groundwater flows before and after the installation of the compacted clay liners. 1.1 HISTORIC USE The Windsor East property has historically been used for agriculture. The adjacent neighbors include Martin Marietta's Parsons Mine site to the east, agricultural land with a few residences to the north and west, and the Cache la Poudre River to the south. Based on well registration, land use besides agriculture within two miles of the site has included Eastman Kodak to the west and northwest, Front Range Energy to the northwest of the site, Joseph Energy to the northwest of the site, and Hensel Phelps Construction to the northwest of the site. OTETRA TECH Page 2111 Windsor East Mine, Exhibit G — Water Information September 2022 1.2 HYDROGEOLOGIC SETTING 1.2.1 Geology The geology mapped at land surface beneath the site consists of quaternary age valley -fill deposits comprised of sand, silt and gravel primarily (Figure G-2). The areas of higher elevation around the site are typically comprised of quaternary terrace deposits. Boring logs from installation of monitoring wells immediately east of the property were reviewed for details on the site geology. The Parsons sand and gravel mine has 12 monitoring wells on the property, including MW -12 which is the nearest to the Windsor East property, located between the Parsons property and the Windsor East property (Figure G-3). The boring logs generally indicate that the geology consists of a 10-30 ft thick layer of unconsolidated alluvial sediments overlying siltstone bedrock. The upper 4-14 feet of the alluvial sediments are typically finer -grained silts and clays and may be only partially saturated in many locations. The lower 4-20 feet of the alluvium consists of sands and gravels which are expected to be highly transmissive of shallow groundwater. The shallow bedrock of the Fox Hills Sandstone consists of weathered, consolidated sedimentary rock varying from claystone to siltstone as observed in the boreholes advanced on the Parsons mine property to the east. In comparison to the alluvium, the weathered bedrock is expected to be several orders of magnitude less transmissive due to the consolidated, finer -grained properties. Bedrock was encountered in the boreholes advanced at the Windsor East mine property between 15 and 22 ft below ground surface (bgs), and 13ft bgs in the nearest Parsons Mine borehole (Parson MW -12). 1.2.2 Groundwater Groundwater at the site represents a combination of water that flows through the high -permeability valley -fill alluvial deposits parallel to the Cache la Poudre River and water which infiltrates in the surrounding higher -elevation recharge areas to the north and south of the river, typically associated with the agricultural fields that dominate the land use of the area. Infiltrating water in these areas of higher elevation drain at the lower -lying erosional valleys formed by streams and rivers of the area, resulting in flow patterns that resemble a muted form of the land surface topography. The erosional valleys are typically underlain by the higher -permeability sands and gravels deposited by historic flood events and form channeled zones through which groundwater can flow more rapidly. South of the Windsor East property, the Cache la Poudre River is the surface -water feature for local groundwater discharge. Within several hundred feet of the river, groundwater flows in a direction that is near parallel to the river due to the constant interaction with the river stage within the porous sands and gravels. As a result, while groundwater beneath the site is typically slightly higher than that of the river and flows toward the river, the flow direction of groundwater flow is generally parallel to the Cache la Poudre River from west to east at close proximity (Figure G-5). Some minor component of upward groundwater flow from the deeper bedrock may occur, but this is likely to be negligible compared to the influence of the river and the undertow within the valley -fill alluvium. The direction of regional shallow groundwater flow is therefore toward the southeast but changing to a near easterly direction near the river. Based on water -level measurements in the monitoring wells installed at the Windsor East mine property, the water table is approximately 8-11 feet below land surface. 1.3 EXISTING AND PLANNED WELLS 1.3.1 Existing Monitoring Wells A network of monitoring wells was installed in 2010 to characterize the groundwater conditions at the Parsons mine east of the Windsor East property (Figure G-3). The boreholes for the wells were drilled to the bedrock contact and the wells were constructed using 8-10 foot screened intervals between the water table and the bedrock contact. These wells generally show the direction of groundwater flow in an easterly direction, in equilibrium with the river water elevations, although subject to the influence of the Parsons mine cell dewatering. TETRA TECH Page 3111 Windsor East Mine, Exhibit G — Water Information September 2022 1.3.2 Well Inventory In May 2022, a well inventory of the Affected Area and adjacent areas was conducted to identify wells near the project. The inventory included a search of the State of Colorado Office of the State Engineer database of wells located within 'A mile of the Affected Area (Table 1). The well inventory identified 25 constructed wells within 'A mile of the Affected Area. Figure G-4 enclosed shows the Affected Area and the constructed well locations on file with the Colorado Division of Water Resources. Wells located within 600 feet of the Lease Boundary The well inventory identified two wells completed in the alluvial aquifer within 600 feet of the lease -area boundary. The first is a monitoring well (Parsons MW -12) owned by Martin Marietta (permit # 280593) associated with the Parsons mine immediately to the east of the Windsor East property. Bedrock was encountered at 13 ft bgs and water was observed at approximately 6-8 ft bgs. The second is a monitoring well owned by Hall -Irwin Corporation (permit # 277000). It was constructed in 2007 and was screened from 4 to 15 ft bgs. Bedrock was encountered at 13 ft bgs and water was observed at approximately 2 ft bgs in 2007. Monitoring holes and wells are not a concern for dewatering impacts because neither are allowed to serve as pumped sources of water. Water supply wells located within'4 mile of the Lease Boundary In addition to the wells identified within 600 feet of the lease boundary, the well inventory identified two residential wells, eight monitoring/observation wells, three monitoring holes, and one general purpose well completed in the alluvial aquifer within 'A mile of the lease -area boundary. Permit number 89706-A Domestic/Residential well (89706-A) is registered to Brett T and Mary K Lauer. It was constructed in 1977 to a depth of 32 feet. It is located slightly more than 600 feet distance from the lease boundary on the northwest corner, and approximately 1,060 feet northwest from the nearest planned mining cell. The well is 5 -inch diameter PVC, screened from 17 to 32 ft bgs, and was equipped with a pump capable of 30 gpm. The driller's log indicates that water was encountered at 12 feet bgs in 1977. A 6 -hr pumping test conducted in 1977 resulted in sustained pumping of 20 gpm and a pumping water level of 27 ft bgs (15 feet of drawdown, a specific capacity of 1.33 gpm/ft). Bedrock was observed at 27 ft bgs. Permit number 113762--A Domestic well (113762--A) is registered to M WaterCo LLC, although originally to Harold Long and Sons. It was constructed in 1980 to a depth of 25 feet. Water was noted at 12 ft bgs and bedrock was encountered at 20 ft bgs. A sustained pumping test of 30 gpm for 2 hours was conducted in 1980 with no recorded drawdown. It is located 1500 to 2000 feet distance from the lease boundary on the north side. A registered domestic well with a similar permit number (113762-) is associated with Harold Long and Sons Inc. The date of construction was not recorded, but the well inventory indicates that it was drilled to a depth of 30 feet, encountering bedrock at 20 ft bgs. This well shares nearly identical location and construction information (and permit number) with the well registered to M WaterCo LLC and seem to be the same well. The parcel that this well sits on is owned by GWIP LLC, the property owner for this reclamation permit application. Permit number 1472 -R -R General Purpose well (1472 -R -R) is registered to West Weld Ag Investors. This well was originally drilled for Allen Lamb with permit number 1472 before 1957 and listed as an irrigation well. It was replaced by well 1472-R at an unknown date to a depth of 15 ft bgs, with a 40 ft by 60 ft sump from which water was pumped at approximately 500 gpm. A permit application was received in 1981 to replace well 1472-R with a new irrigation well by West Weld Ag Investors with a proposed maximum pumping rate of 500 gpm and a planned depth of 50 ft. The registered UTM coordinates for the well indicate that it is located several hundred feet south of the Cache la Poudre river, but the description in the permit indicate that it is located 3,300 ft south of the northern edge of section 35 and 1,300 ft west of the eastern edge of section 35, and therefore may actually be located just north of the river near UTM 512260 E, 4476810 N. This location is approximately 1,200-1,300 ft west of the southwestern OTETRA TECH Page 4111 Windsor East Mine, Exhibit G — Water Information September 2022 corner of the lease boundary, and approximately 1,500 ft from the nearest planned mining cell. A loop of the Cache la Poudre River extends between the lease area and the likely location for the well. The parcel that this well sits on is owned by GWIP LLC, the property owner for this reclamation permit application Wells on the Adjacent Parsons Mine Property Monitoring wells installed as part of the Parsons Mine operations were considered as part of this permit application. Twelve of the fourteen wells were installed in 2010 and the other two were installed more recently. Table 2 includes construction details and depth -to -water information. Measuring point elevations are believed to have been estimated based on a topographic map for the area. Appendix G-2 provides water levels measured over time for the Parsons Mine monitoring wells. 1.3.3 Site Monitoring Wells Martin Marietta installed five monitoring wells (Figure G-3) in August 2022 to support the monitoring plan associated with the project, documenting the groundwater conditions before initiation of mining, during mining, and after mining is complete. Through the well monitoring program, the wells will serve as points at which water levels will be measured and water quality samples collected. The boreholes for each of the wells were advanced until bedrock was encountered. Lithologic logs documenting the valley -fill sediments observed and the bedrock during drilling were recorded. The monitoring wells were constructed of two-inch Schedule 40 PVC casing and screen. Silica sand was placed from approximately two feet above the top of the screen to the bottom of the borehole (bedrock). Above the silica sand, a bentonite seal was placed in the borehole annulus to restrict infiltration of surface water. Each of the monitoring wells was finished at the surface with a locking, aboveground, steel protective casing set in concrete. Table 3 provides additional details of the monitoring well installations. Appendix G-1 presents borehole logs and well completion details for the monitoring wells. 1.4 HISTORIC AND FUTURE GROUNDWATER LEVELS Monitoring wells established at the Windsor East site in August 2022 were used to collect groundwater elevation data. This set of water level data was supplemented by water level data collected from monitoring wells on the adjacent Parsons Mine site located east of the Windsor East property. Water level data measured for the wells are included in Tables 2 and 3. Depth to water at the Windsor East site varies from 7.9 to 10.4 ft below the top of the well casing, corresponding to a range of water level elevation from 4732.14 at MW -06 to 4717.44 at MW -11. Figure G-5 presents the general direction of groundwater flow (southeast). Since 2010, regular groundwater measurements have been collected from the 14 monitoring wells around Martin Marietta's Parsons Mine site. These wells shall hereafter be referred to as the Parsons Well Network, are numbered MW -1 through MW -14. Appendix G-2 shows the variation in water level measurements from monitoring wells MW -1 to MW -12. Water levels measured in the Parsons well network vary from 4730 feet at MW -5 to 4690 feet above mean sea level (amsl) at MW -1 where the effects of dewatering are visible in late 2021 through 2022. Water levels are seasonally at their highest elevations in August or September following the irrigation season, and typically at their lowest elevations in February to March when irrigation has been suspended for the longest period of time. The water level at MW -12 before initiation of local dewatering in 2019 ranged from 5.8 to 7.8 ft bgs (4720.5 to 4722 ft amsl), then dropped to an average of 11.3 ft bgs (4716.7 ft amsl), a drawdown of approximately 4.6 ft. This monitoring well is located approximately 100 feet from the dewatering trench of the nearest active mining cell at the Parsons Mine, and the 4.6 -foot change in water levels experienced at the Parsons Mine is expected to be representative of the drawdown that will be associated with dewatering of the mining cells at the Windsor East site. Based on observed water levels at the Windsor East and Parsons sites, dewatering will lower water levels to within 2 feet of the top of bedrock in the immediate vicinity of each mining cell. The lowered groundwater effects will be transmitted horizontally by the gravel aquifer, reducing water levels in the surrounding area as a "cone of depression" forms around the mining cell. During mining, water in the area will flow radially toward the dewatered cells, where it will be removed using the dewatering trench drainage system and discharged into the river. OTETRA TECH Page 51ll Windsor East Mine, Exhibit G — Water Information September 2022 Following mining, each cell will be lined to form a hydraulically isolated reservoir. The effect of the clay liner on the groundwater within the aquifer will be the formation of a hydraulic mound upgradient of the cell where water levels will be several feet higher than under pre -mining conditions. Downgradient of the cell, the groundwater levels will be several feet lower due to a "shadow effect" behind the reservoir. These changes in groundwater levels due to the clay -lined cells are expected to have minimal effect on the groundwater in the surrounding area due to the proximity of the river adjacent to and downgradient of the lined cells. Downgradient of the lined cells, groundwater levels will reach an equilibrium with the river due to its proximity, thereby minimizing the "shadow effect" 1.5 AVAILABLE SATURATED THICKNESS The drilling and installation of monitoring wells at the Windsor East site in August 2022 indicated that bedrock was encountered between 15 and 22.5 feet below land surface. Water levels measured on August 12, 2022, ranged from 7.9 to 10.4 feet bgs. Based on this data, the saturated thickness of aquifer present beneath the site ranges from approximately 5 to 13.5 ft (Table 3). The lowest saturated thickness was recorded in MW -11 on the eastern side of the site, which is likely showing the direct impact from dewatering activities associated with the adjacent Parsons mine. Dewatering activities required as part of mining in the absence of a hydraulic barrier wall result in drawdown of the water table and associated decrease in saturated thickness of the alluvium. This has the potential to impact other wells nearby if the decline in water levels is sufficient to prohibit the well owner from extracting the associated water rights from the well. Table 4 presents historic information about the variability in saturated thickness near the site and the impact from mining based on available data. Four of the monitoring wells that were installed at the Parsons Mine Site to observe water levels at the Parsons Mine site, provide evidence of the saturated thickness of alluvium nearest to the Windsor East property. Water levels measured during pre -mining and mining conditions illustrate the expected decline in saturated thickness at a distance of approximately 100 feet from the gravel mines. In particular, the Parsons Mine monitoring well MW -12 is located approximately 100 feet west of a cell that began dewatering and mining in 2019. The water level record for the well shows the range of saturated thickness for the alluvium before and during dewatering activities at this distance. MW -12 is located on the eastern edge of the Windsor East property and is therefore expected to be representative of the conditions at the site as well as of the expected impacts from dewatering during mining near the property boundary. Before 2019, the water table was an average of 6.3 feet above the top of the bedrock at MW -12 and fluctuated over a range of approximately 1 foot above or below this average. During dewatering, the depth to water increased, and the saturated thickness decreased until it was an average of 1.7 feet above the top of the bedrock, with a variation range of approximately 1 to 1.5 feet. Water wells completed in sand and gravel aquifers typically provide approximately 25 to 30 gallons per minute per foot of drawdown of saturated thickness in the well. Domestic wells are typically permitted for maximum pumping rates of 15 gallons per minute (gpm). As a result, less than 2 feet of saturated thickness above the pump intake is therefore likely to be required to provide the allowed pumping rates of 15 gpm. The reduction of saturated thickness of 4.6 ft at MW -12 to 1.7 ft above bedrock suggests that the potential for impact to a domestic well at this distance is likely, however wells located further from the lease boundary will have more saturated thickness and hence will likely be able to pump the permitted rates. 1.6 MODELED HYDRAULIC IMPACTS The hydraulic impacts associated with dewatering around the planned mine cells are expected to spread outward as a function of the aquifer properties of the alluvium, the time elapsed since dewatering began, and the distance of observation from the point of dewatering. The previous observations of the depressed water table (drawdown) due to mining at the adjacent Parsons mine (noted in the previous section) are useful for predicting the impact of the Windsor East mine. In particular, the observations at Parsons well MW -12 (located directly between a dewatered cell and the Windsor East site) represent an ideal location from which the effects of dewatering in the TETRA TECH Page 6111 Windsor East Mine, Exhibit G — Water Information September 2022 vicinity can be observed. As noted in Table 4, the result of dewatering at MW -12, located at a distance of approximately 100 ft from the nearest cell, resulted in drawdown of 4.6 ft. This response occurred over two years, since dewatering was variable depending on mining rates. A simplified model assuming a saturated thickness of 8 feet was developed based on the observed impacts of dewatering at the adjacent Parsons mine. Hydraulic conductivity of 0.05 cm/s (representative of a sandy gravel) and a specific yield of 0.2 was used to simulate the aquifer. A head boundary was fixed at a radial distance of 1 mile. Simulation of dewatering of a 500 -foot x 500 -foot mine cell was performed to reduce the hydraulic head at the mine cell to a hydraulic head 1.5 feet above the top of bedrock. This simulation resulted in a reduction of head at a point 100 ft away by 4.6 ft after approximately two years, which is the same as was observed at MW -12. The isolated effects of propagation of drawdown for various distances at 1 year and 5 years into dewatering is shown below. After 5 years, a new "steady-state" set of conditions has established, minimizing the further lowering of the water table. Drawdown (ft) Distance 1 year 5 years 100 ft 4.4 4.8 200 ft 3.6 4.1 500 ft 2.3 3 600 ft 2 2.7 1000 ft 1.3 2.1 2000 ft 0.5 1.1 2640 ft 0.2 0.8 There are likely mitigating factors to this drawdown spread. Active dewatering may stop and start at a location depending on the mining progress, the proximity of the Cache la Poudre River will provide a constant source of water mitigating drawdown impacts, and the aquifer may prove more or less transmissive depending on the location. With this understanding, the modeled spread of the hydraulic effects of dewatering suggests that the impact of the lowering of the water table during mining is unlikely to substantially affect any nearby water wells. 1.7 WATER USE Section 6.4.7 of the Colorado Mined Land Reclamation Board's Construction Material Rules and Regulations: (3) The Operator/Applicant shall provide an estimate of the project water requirements including flow rates and annual volumes for the development, mining and reclamation phases of the project. (4) The Operator/Applicant shall indicate the projected amount from each of the sources of water to supply the project water requirements for the mining operation and reclamation. Water use will be at its highest during the mining phase of the project. Mining at the site will intercept groundwater tributary to the Cache la Poudre River. Consumptive uses of groundwater at the site include evaporation from groundwater exposed to the atmosphere, water retained in material hauled off -site for processing, and water used for dust control. Evaporative losses at the site are attributable to exposed groundwater in the dewatering trenches for each mine cell. Evaporative losses were calculated as the difference between gross evaporation and effective precipitation. The NOAA Technical Report NWS 33, Evaporation Atlas for the Contiguous 48 United States (U.S. Department of Commerce) was used to determine the site's average annual gross evaporation of 43 inches. Precipitation was obtained from the Western Regional Climate Center for the Fort Collins weather station (053005). The gross annual precipitation for this site was determined to be 15.08 inches. Effective precipitation was calculated as 70 TETRA TECH Page 7j11 Windsor East Mine, Exhibit G — Water Information September 2022 percent of gross precipitation; thus, the average annual effective precipitation was determined to be 10.56 inches. The resulting evaporative loss rate is therefore 27.92 inches. The maximum total annual evaporative consumptive use at the site is estimated at 12-17 acre-feet, which is primarily a function of the water used for dust control (10-15 ac-ft/yr). 2.0 MONITORING AND MITIGATION PLAN This Groundwater Monitoring and Mitigation Plan is prepared as part of Martin Marietta's application to the Colorado Division of Reclamation, Mining and Safety (DRMS) for a permit for the Windsor East Mine in Weld County, Colorado. This plan presents the methods and locations for monitoring of groundwater during gravel mining and site reclamation activities. Although adverse impacts to other local users of groundwater are not expected as a result of activities at the mine, this plan addresses how any adverse effects to groundwater would be mitigated, should they occur. Martin Marietta will submit a Temporary Substitute Water Supply Plan to the State Engineer's Office for approval. The temporary substitute supply plan is designed to protect senior vested water rights and mitigate potential depletions of flows in adjacent waterways. 2.1 MINING PLAN Except for Cell A, the mining plan has been designed to allow for up to five quarters worth of groundwater monitoring to occur before excavation below the water table occurs. To allow for sufficient time for groundwater characterization to occur, mining is only planned to occur in the unsaturated zone until one year's worth of monitoring and groundwater sample collection has been conducted. An exception will be made with regard to mine Cell A. This cell is the eastern -most cell in the mining plan and is located within several hundred feet of the Parsons mine. As a result, water levels are already lowered in the area from Parsons dewatering. Since changes to the groundwater flow regime have already been substantially implemented, trenching and mining below the water table at Cell A with associated dewatering will begin before the five quarters of monitoring is complete. Following the five quarters of monitoring, dewatering trenches will be excavated around the perimeter of each remaining mine cell on a schedule determined by the mining plan. Dewatering will occur initially adjacent to the area on the east where dewatering associated with Parsons mine has already reduced water levels (Cell A). The bottom of the trench will be maintained at or deeper than the deepest point in the excavated mine cell, thereby intercepting all groundwater before it reaches the mine cell. After collection of five quarters of groundwater monitoring, mining will gradually progress westward, with perimeter dewatering drains preceding excavation below the water table. Groundwater flow into each dewatering trench will be accumulated in connected sumps and discharged directly into the Cache la Poudre River. Following completion of mining activities, each mine cell will be finished with a compacted embankment liner from material located on -site, keyed into the bedrock at the base of the mine cell, thus forming a low -permeability bathtub in the mine cell. Once finished, dewatering of the perimeter trench will cease, and the trench will be backfilled, allowing groundwater to return to a state of natural flow around the now -lined mine cell. It is expected that some minor hydraulic mounding may occur upgradient of the lined mine cell, with some "shadow effect" (decline in groundwater level) downgradient of the mine cell. Since no existing water wells have been identified downgradient between the mine and the river, the shadow effect is not anticipated to impact other users. Figure G-6 depicts the anticipated groundwater flow directions resulting from the installation of the compacted liners during reclamation. 2.2 MONITORING The monitoring plan will consist of regular data collection from the set of five monitoring wells installed around the perimeter of the Windsor East property (Figure G-3). Data collection activities will include measurement of water levels in wells and sampling of water quality from wells and surface discharge locations. TETRA TECH Page 8(11 Windsor East Mine, Exhibit G — Water Information September 2022 2.2.1 Water Quality Parameters Martin Marietta will collect water samples from each of the wells and discharge outflow sites and submit the samples to an analytical laboratory to determine water quality for a set of parameters. The DRMS recommends a set of parameters for analysis for aggregate mine permitting. These include a list of dissolved metals, radiological parameters, and miscellaneous parameters which include pH and total dissolved solids (TDS). The nature of activities associated with sand and gravel mining involves excavation of large volumes of aggregate materials using industrial machinery. These activities inherently do not result in the generation or release of coliform bacteria, asbestos, chlorophenol, foaming agents, odor or phenol compounds. They also don't result in a change in corrosivity of water, or color change. As a result, these parameters which are otherwise a part of the DRMS requirements for water quality analysis are excluded from the list of water quality parameters. Likewise, sand and gravel mining does not lead to the generation or release of gross alpha or beta and photon emitters as part of the operation. Martin Marietta acknowledges the preference on the part of DRMS to have gross alpha radiological analysis performed and will include it in the list, but excludes beta and photon emitters from analysis. Table 5 presents the complete list of water quality parameters proposed for analysis. 2.2.2 Windsor East Monitoring Wells The monitoring plan will consist of regular data collection from the five monitoring wells installed around the perimeter of Windsor East (Figure G-3). Monitoring data will be used to identify potential changes in alluvial groundwater flow or elevation associated with mining and reclamation activities. Baseline data collected from the monitoring program will provide a range of relative water levels associated with pre -mining groundwater conditions. Experience at other sand and gravel mine sites in similar geologic settings shows that groundwater levels tend to fluctuate between two to four feet each year; levels are highest in the summer and lowest in the winter and early spring. Martin Marietta will conduct monthly water level monitoring for the five monitoring wells around Windsor East during dewatering and until groundwater levels have recovered once dewatering ends. Groundwater samples will be collected to document baseline water quality prior to mining, then determine whether any changes have occurred as a result of mining activities. One quarterly water quality sample for laboratory analysis will be collected during each of the five quarters of monitoring to document the baseline water quality around the mine. Based on the historical water level fluctuations observed in the wells associated with the Parsons Mine, the seasonal high and low water levels for groundwater have been evaluated. Water levels are seasonally at their highest elevations in August or September following the irrigation season, and typically at their lowest elevations in February to March when irrigation has been suspended for the longest period of time. During high groundwater levels, the sample is expected to be representative of the groundwater which flows from the agricultural fields toward the river, and during the periods of low groundwater the sample is expected to be representative of alluvial channel water flowing from the west. After five quarters, water quality sample collection will continue to be conducted twice per year while mining, with sample collection timed to be consistent with high and low groundwater levels. The results of water quality sample analysis will be provided to DRMS following the baseline water quality evaluation, and during annual reporting thereafter. Appendix G-3 includes procedures for collecting water samples. These procedures include a process of pumping to purge standing well water, then using the pump to remove water for sample collection, then placing the water in sample bottles obtained from the analytical laboratory. At the end of purging, the pH of the water will be recorded using a handheld pH meter. Samples for dissolved constituents, primarily inorganics and metals, will first be filtered through a 0.45 -micron filter to remove suspended solids. Samples will then be stored on ice in a cooler for transport and submitted for analysis of the constituents listed in Table 5 under chain -of -custody protocols. If sufficient data is collected during the life of the mining operation, and a demonstration can be made that project impacts to the groundwater system have been minimized, Martin Marietta may request the approval of a Technical Revision to revise the water level monitoring frequency or water quality sample collection frequency at a later date. OTETRA TECH Page 9(11 Windsor East Mine, Exhibit G — Water Information September 2022 2.2.3 Domestic and Irrigation Water Wells No active water wells (water -supply wells) were present within 600 ft of the lease area. 2.2.4 Dewatering Discharge Based on data collected from monitoring wells on the adjacent Parsons Mine property, the depth to groundwater fluctuates by two feet depending on the season but averages about 7 feet below ground surface. Due to the absence of large quantities of potential pollutants on site (no on -site processing or concrete or asphalt production), the mining and reclamation operations are not likely to affect groundwater quality on or off the site. Martin Marietta's Parsons facility complies with applicable requirements in the site CDPS General Permit COG501594 for Discharges Associated with Sand and Gravel Mining and Processing. CDPHE WQCD considers stormwater runoff combined with mine dewatering water to be process water. Currently permitted discharges at the Martin Marietta Windsor East Site and Parsons Pit are permitted as process water discharges. As such, process water discharges are subject to the process water provisions in the general permit. Martin Marietta plans to obtain a City of Windsor Grading, Erosion and Sediment Control Plan (GESCP) Permit and comply with applicable requirements as stated in the City of Windsor's Municipal Code/Ordinance Chapter 13, Article, Stormwater Quality. 2.3 MITIGATION The available monitoring well data will be used to identify changes in alluvial groundwater flow associated with mining and reclamation activities. Baseline data collected from the monitoring program will provide a range of relative water levels associated with pre -mining groundwater conditions. These data will be utilized to evaluate the nature and extent of the change to the prevailing hydrologic balance and if necessary, provide for the development of corrective actions. Well owners in the section below refer specifically to owners of wells from which extracted water is put to beneficial use, such as water wells, irrigation wells, etc. Owners of monitoring wells are not considered well owners in this context, since a change in water levels for these wells does not represent material damage. In the event of a well owner complaint within 600 feet of the Affected Area, Martin Marietta will review the available monitoring information and submit a report to the DRMS within 30 days. The report will include discussions with any well owner who has contacted Martin Marietta regarding a concern and a review of baseline data from the well and vicinity to evaluate whether changes may be due to seasonal variations, climate, mining or other factors. The report will identify the extent of potential or actual impacts associated with the changes. If the extent of groundwater changes due to mining or reclamation activities is determined to be a significant contributing factor that has or may create adverse impacts, the mining -associated impacts will be addressed to the satisfaction of the DRMS. If the DRMS determines that the impact on a well for which temporary mitigation has been initiated is not a result of Martin Marietta's activities or is not solely a result of Martin Marietta's activities, Martin Marietta will reduce or cease mitigation accordingly. If a well goes dry, Martin Marietta will implement mitigation measures within 7 days. Mitigation measures would include providing a temporary alternative water supply that meets the documented historic well production, or need until further investigation can be conducted to determine if the well condition is due to the mining operation. Martin Marietta will begin to implement one or more mitigation measures if mining or reclamation activity is determined to be a significant contributing factor to groundwater changes requiring mitigation. Temporary mitigation measures may include, but are not limited to: • Compensation for well owners to use their existing treated water system to replace the well production loss; • Provision of a water tank and delivery water as necessary to meet documented historic well production or need; • Other means acceptable to both the well owner and Martin Marietta. OTETRA TECH Page 10111 Windsor East Mine, Exhibit G — Water Information September 2022 Long-term mitigation measures may include, but are not limited to: Cleaning a well to improve efficiency • Providing an alternative source of water or purchasing additional water to support historic well use with respect to water quantity and quality. If needed, water quality parameters will be checked in affected wells to ensure alternative sources support the historic use Modifying a well to operate under lower groundwater conditions. This could include deepening existing wells or lowering the pumps. All work would be done at Martin Marietta's expense except for replacing equipment that was non-functional prior to mining. • If existing wells cannot be retrofitted or repaired: replace the impacted well with a new replacement well. • Design and installation of a cistern If a groundwater mitigation action is required, Martin Marietta will notify the DRMS of the condition, action taken and report the results and present a plan for monitoring the mitigation.

In this SOP, wells are defined as monitoring wells, piezometers, temporary well points, and potable wells. Permanent wells should be surveyed such that wells can be located and water elevations can be determined. At sites where there are multiple wells, a complete round of water level measurements should be collected site -wide prior to commencement of activities that will affect groundwater levels. A permanent survey mark should be placed on the top of the well casing (TOC) as a reference point for groundwater level measurements. If the lip of the riser pipe/well casing is not flat, a notch can be made on the polyvinyl chloride (PVC) riser and used as the reference point. Alternatively, the reference point may be located on the top of the outer protective casing (if present). If using a measurement reference point, it must be documented in a site -specific logbook or on a field data sheet. All field personnel must be informed of the measurement reference point used to ensure the collection of consistent data. 1.2 WATER -LEVEL MONITORING An electronic water -level indicator is used to measure the depth to water in each well. The indicator consists of a wired cable with a probe at the end. When the probe contacts water, the water completes a circuit causing the indicator to emit a sound at the surface. The water -level indicator should be turned on, then lowered until the probe emits a tone indicating contact with water. The distance from the water surface to the TOC should then be recorded using the gradational scale on the cable. The water level measurement should be recorded on a water - level monitoring field form or notebook, then the measurement should be repeated to confirm the reading. All measurements should be recorded to one hundredth (0.01) of a foot. It is important to record the date and time of each measurement along with the well identification and the depth -to -water value since water levels can vary over time. Water level measuring equipment will be cleaned of visible water and particulate matter prior to and after use at each measuring location via wiping/rinsing. The groundwater elevation can then calculated by subtracting the depth -to -water measurement from the surveyed TOC elevation. 1.3 WATER QUALITY SAMPLE COLLECTION The procedure for collecting a water quality sample involves the use of a pump or bailer to remove three well - volumes of water from the well to ensure that the water remaining is representative of aquifer water, then to use the pump or bailer to pass samples of water through a filter to remove suspended particles and collect the filtered sample in a bottle. 1.3.1 Well Purging An adequate purge is normally achieved using this method by removing three well volumes of standing groundwater at relatively high flow rates prior to sampling while recording the pumping rate, discharge volume, water level and routine groundwater parameters over time. Routine groundwater parameters should include temperature, pH, and specific electrical conductance at a minimum, but may additionally include turbidity. It is OTETRA TECH Page 114 Windsor East Sand and Gravel Mine; Martin Marietta Materials June 2022 assumed that stabilization of the groundwater measurements indicates the purge water is representative of ambient water from the underlying aquifer. Groundwater quality parameters are generally considered stabilized after three consecutive sets of readings do not vary by more than 10 percent (%), however the criteria for sample collection will be based on purge volume, rather than parameter stability. The time between readings (typically 5 to 10 minutes) should be chosen to ensure enough data have been collected to document the stability of parameters. If the calculated purge volume is large, measurements taken every 15 minutes may be adequate. To calculate the volume of a well, use the following equation: Well Volume (gallons) = rrr2hk where: rr = 3.14 r = radius of monitor well (feet) h = height of the water column (feet). (This may be determined by subtracting the: depth to water from the total depth of the well as measured from the same reference point). k = conversion factor, 7.48 gallons per cubic foot (gal/ft3) The volume, in gallons per linear foot, for various standard monitoring well diameters (nominal): Well diameter (inches) 2 3 4 Volume (gal/ft.) 0.1631 0.3670 0.6528 1.3.2 Sample Preservation and Containers Groundwater samples will be collected in bottles which are chosen to be appropriate for the analysis by an analytical laboratory, and may be supplied directly by the laboratory. The analytical method specifies the type of bottle, preservative, holding time and filtering requirements for a groundwater sample. Samples should be collected, when possible, directly from the sampling device into appropriate sample containers, with an appropriate sample identification label. Record all pertinent data in a site -specific logbook and on a laboratory - supplied chain of custody (COC) record. The samples should be placed in a cooler and maintained at less than or equal (5) to 4 degrees Celsius (C) and protected from sunlight. Ideally, samples should be transported to the analytical laboratory within 24 hours of collection. If large numbers of samples are being collected, shipments may occur on a regular basis after consulting the analytical laboratory. In all circumstances, samples need to be analyzed before the holding time expires. 1.3.3 Sample Collection After purging, groundwater samples may be collected using a bailer or the flow -stream from the pump. Samples collected for dissolved metals analysis require filtration. Groundwater is primarily filtered to exclude silt and other particulates from the samples that would interfere with the laboratory analysis. In -line filters (typically 0.45 -micron) are used specifically for the preparation of groundwater samples for dissolved metals analysis, and for filtering large volumes of turbid groundwater. An in -line filter can be used with a peristaltic pump to transfer the sample from the original sample bottle, through the filter, and into a new sample container. The filter must be replaced between sampling locations. TETRA TECH Page 214 Windsor East Sand and Gravel Mine; Martin Marietta Materials June 2022 The filters used in groundwater sampling are self-contained and disposable. Disposable filters are preferred and often used to reduce cross -contamination of groundwater samples. Disposable filter chambers are constructed of polypropylene material, with an inert filtering material within the housing. The proper collection of a sample for VOC analysis requires minimal disturbance of the sample to limit volatilization. The following procedures are required to be used: 1. Open the vial, set cap in a clean place, and collect the sample. When collecting duplicate samples; collect both samples at the same time. 2. Fill the vial to almost overflowing. Do not rinse the vial, or let it excessively overflow. It needs to have a convex meniscus on the top of the vial before securing the cap. 3. Check that the cap has not been contaminated and place the cap directly over the top and screw down firmly. Do not over tighten the cap. 4. Invert the vial and tap gently. Observe vial for at least 10 seconds. If an air bubble appears, unscrew the cap and pop the bubble or refill with more sample then re -seal. Do not collect a sample with air trapped in the vial. 5. The holding time for unpreserved samples to be analyzed for VOCs is 7 or 14 days for preserved samples. Samples should be shipped or delivered to the laboratory as fast as practical in order to allow the laboratory time to analyze the samples within the holding time. Ensure that the samples are stored at ≤ 4 degrees C during transport but do not allow them to freeze. 1.3.3.1 Bailer Purging Wells are typically purged using either pumps or bailing. Bailing is a process in which a plastic disposal bottom loading bailer with a string or thin rope attached is lowered by hand into a well, allowed to fill with water, and then retrieved. Once retrieved the waterin the bailer is decanted into containers on the ground surface for subsequent disposal. Manual bailing, or the use of dedicated or disposable bottom loading drop bailer approximating 3 feet in length and one liter storage capacity, attached by a string or rope to remove water from a small diameter well for well development and/or sampling is performed as follows: • Open the well protector top, typically removing the protective lock and/or unbolting the cover, to access the well riser piping. • Affix the bailer to the rope, string, or cord with a knotting technique that will ensure its permanent attachment and prevent bailer loss over the course of the purging cycle. Knots can loosen or slip when the rope becomes wet in conjunction with the application of the additional weight of the full bailer. • Place the bailer in the well and lower it to the water table surface, slowly allowing the bailer to sink and fill with water (this avoids turbulent flow of water in the wells casing and minimizes off gassing). • Retrieve the bailer by manually pulling the attached rope by either coiling it hand over hand or allowing it to collect onto the plastic sheeting on the ground until the bailer exits the well riser. Then grasp the bailer and decant the purge water into a bucket or other interim container. This procedure is repeated until the prescribed volume of water has been purged from the well. 1.3.3.2 Mechanical Pump Purging Small diameter electric submersible pumps may be employed for some circumstances. Comparatively high volume pumps, such as a "Whale" or "Keck" model/brand employ a 12v battery or rechargeable power source may be used individually or in series to accommodate deep pumping situations or increase pumping volume. QTETRA TECH Page 3)4 Windsor East Sand and Gravel Mine; Martin Marietta Materials June 2022 Although this document does not provide a specific description for the use of each type of pump, the application and field use of a small diameter 12v pump such as a "Whale Pump" or equivalent is as follows: • Measure the overall well depth and construct the pump with supply tubing "string" accordingly, allowing extra tubing length as necessary to accommodate discharge to storage and/or sampling containers. The electrical wire supply line should be of adequate gauge and constructed to a length sufficient to access a nearby power source. Multiple "in -line" pumps may be used in accordance with manufacturers suggested recommendations to facilitate an adequate pumping rate and volume in deep wells. • Lower the supply tubing with attached pump(s) in the well to the desired depth, commonly near the well bottom or lower level of the screened interval. The pumping "string" can be affixed to a permanent object, typically the riser protective piping, with a small clamp to keep the pumps from contacting the bottom of the well or maintain a desired or prescribed sampling depth. • Attached the electrical supply wires employing small clamps on the positive (+) and negative (-) battery terminal in the event a standard 12v automobile battery is utilized as power source or insert the plug to the cigarette plug- in if wired accordingly. There will be a short delay until the pumps engage and flow is actuated if wired correctly and the power source is adequate. • As water flows from the supply tubing, place the purged water into an interim storage container, commonly a five -gallon bucket, for transport to a long term storage or staging area pending disposal analysis. The direct discharge of purged water may be warranted based on historical site findings or client direction. • Continue with the pumping/storage/disposal routine until the desired or prescribed volume of water has been removed.

(Pinyon) to evaluate potential wildlife habitat impacts, including the determination of threatened or endangered (T&E) species habitat for the Windsor East Mine Site in Weld County, near Windsor, Colorado. This Exhibit summarizes Pinyon's Biological Resources Technical Memorandum (Attachment H-1) which addresses the wildlife associated with this property. Specific details can be found in the attachment. This 150.3 -acre parcel is located in the Bracewell, Colorado 7.5 -Minute Quadrangle (Sections 35 and 36 of T6N, R67W, of the 6th Principal Meridian) on CR23 along the Cache La Poudre River. Agriculture is the primary use of the site. Primary land uses in the surrounding area include agricultural, industrial, and mining. The Cache la Poudre River runs along the southern edge of the property. 2.0 SIGNIFICANT WILDLIFE RESOURCES The property is dominated by agricultural fields. Species encountered during the site visits include white-tailed deer (Odocoileus virginianus). black -tailed prairie dog (Cynomys ludovicianus), Bald Eagle (Haliaeetus leucocephalus), Swainson's Hawk (Buteo swainsoni), Red-tailed Hawk (Buteojamaicensis), Western Kingbird (Tyrannus verticalis), American Robin (Turdus migratorius), Say's Phoebe (Sayornis saya), Mourning Dove (Zenaida macroura), Killdeer (Charadrius vociferus), Western Meadowlark (Sturnella neglecta), Red -winged Blackbird (Agelaius phoeniceus), and House Finch (Haemorhous mexicanus). Other wildlife species that could be expected to occur in the study area include mule deer (Odocoileus hemionus), raccoon (Procyon lotor), red fox (Vulpes vulpes), skunk (Mephitis mephitis), American badger (Taxidea taxus), and coyote (Canis latrans). 3.0 SEASONAL USE OF THE AREA The site is within a CPW-mapped winter range for mule deer and white-tailed deer. The site also has winter concentration and production of Wild Turkey and Canada Goose (Brenta canadensis). 4.0 PRESENCE AND ESTIMATED POPULATION OF THREATENED OR ENDANGERED SPECIES Pinyon addressed the presence and estimated population of Threatened or Endangered Species in their Memorandum. Please refer to Attachment H-1 for their findings. 5.0 GENERAL EFFECT ON WILDLIFE DUE TO MINING OPERATION Due to the current agricultural use of the land, the area does not provide high -quality wildlife habitat, meaning potential impacts to general wildlife are expected to be minor. The water storage reservoirs that will be created via reclamation of this site will shift the current habitats to an open water habitat. The project is designed to avoid impacts to the Cache la Poudre River and riparian areas. Due to the proximity of Parsons Mine, increased habitat fragmentation resulting from mining activity at this site is not expected to occur. Based on the location of the Windsor East Mine site, the development of the area is not anticipated to impact federally listed species. In Attachment H-1, Pinyon makes the following recommendations related to state -listed and special concern species: • There is a CPW-mapped Bald Eagle winter roost near the property and several Bald Eagles were noted roosting in and near the project area during the site visit. Because there is another mine site closer to the mapped roost, Bald Eagles in the area may be habituated to disturbances associated with mining activities and the area may be considered a Highly Developed Area. Determination of whether a roost is within a Highly Developed Area should be done in coordination with CPW (CPW, 2020). For Highly OTETRA TECH Page 112 Windsor East Mine, Exhibit H — Wildlife Information September 2022 Developed Areas, CPW recommends a seasonal (November 15 — March 15) buffer of 660 feet (1/8 -mile) for disturbances not in direct line of sight and a buffer of 1/4 -mile for disturbances in direct line of sight. If impacts on or near the prairie dog burrows are expected, Burrowing Owl surveys should be completed prior to construction activities that are scheduled to take place from March 15 to October 31. Surveys should be conducted in accordance with the CPW Recommended Survey Protocol and Actions to Protect Nesting Burrowing Owls (CPW, 2021). If active Burrowing Owl nests are found during the surveys, work should be avoided within 660 feet of the active nest (CPW, 2020). There is habitat for the northern leopard frog in the study area. As a special concern species, the northern leopard frog does not have any regulatory protections, and no mitigation is required for this species. Best Management Practices (BMPs) and avoidance measures for waters and wetlands will also benefit this species. Due to the potential for Migratory Bird Treaty Act (MBTA) constraints, if work is to occur during the nesting season for small migratory birds (April 1 through August 31), Pinyon recommends that the project conduct surveys for nests prior to ground disturbance (e.g. clearing and grubbing activities). Work should be avoided within 50 feet of active nests of small migratory birds. If work is to occur during the nesting season for Colorado raptors, Pinyon recommends conducting raptor nest surveys within 0.5 mile of the study area (CPW, 2020). The nesting season for most Colorado raptors occurs between February 15 and August 31, but eagles and certain other species can nest as early as January. If active raptor nests are noted within the CPW-recommended buffer for that species, coordination with CPW and/or USFWS may be necessary. TETRA TECH Page 212 Pillv n Environmental, Inc.

Subject: Biological Resources Evaluation for the Great Western Phase I Lease Area, Weld County, Colorado Introduction Pinyon Environmental, Inc. (Pinyon), has been contracted by Martin Marietta to complete a biological resources evaluation at the Great Western Phase I Lease Area in Weld County, Colorado (Figure 1). Martin Marietta is interested in developing the property and would like to understand potential environmental constraints as they relate to biological resources. Pinyon was provided with the location of the Great Western Phase I Lease Area. This area is further referred to as the "study area" (Figures I and 2). Project Location The studyarea is located near the Town of Windsor, along County Road 23, in Weld County, Colorado (Figure 1). The approximate geographical location of the project is centered at decimal degree coordinates (World Geodetic System of 1984 [WGS84]) latitude 40.446608°, longitude -104.846744°. The project is located in Section 36, Township 6 North, Range 67 West, of the 6th Principal Meridian on the United States Geological Survey (USGS) Bracewell, Colorado 7.5 -Minute Quadrangle (USGS, 2019). The elevation at the proposed project is approximately 4,730 feet above mean sea level. Methods Prior to the site visit, a desktop analysis using Google Earth, U.S. Fish and Wildlife Service (USFWS) data, Colorado Parks and Wildlife (CPW) data, USGS maps, and other existing data sources was conducted to identify potential biological resources. Following the desktop review, Pinyon biologist Mark Fletcher visited the site on January 21, 2022, to assess the study area for biological resources, including general wildlife; state and federally listed threatened, endangered, and special concern species; raptors and other migratory birds; and conduct an initial exploration of potential Waters of the U.S. (WOTUS), including wetlands. Pinyon biologists returned to the site on June 16, 2022, to delineate potential WOTUS within the study area per United States Army Corps of Engineers (USACE) protocols. During the return visit, wetlands and boundaries of non -wetland waters (the ordinary high water mark [OHWM]) were recorded with tablet -based Collector for ArcGIS software paired with a sub -meter accurate Trimble R I global navigation satellite system (GNSS) receiver. Photographs of delineated areas were also taken to document field conditions. Biological Resources Technical Memorandum Biological Resources Evaluation for the Great Western Phase I Lease Area Pinyon Results General Habitat and Vegetation The study area is generally surrounded by agricultural, industrial, and mining properties. The study area is primarily used as an agricultural site, dominated by a monoculture of corn (Zea sp.) covering approximately 80 percent of the site (Figure 2; Photographic Log, Photo 1). The perimeter of the study area is dominated by common disturbed upland habitat with a mixture of native and non-native herbaceous species (Photographic Log, Photo 2). This upland herbaceous habitat comprised approximately I9 percent of the study area and had vegetative heights up to 3 feet and cover generally ranging from 75 to 100 percent. Dominant upland species along the perimeter of the study area consisted of western wheatgrass (Pascopyrum smithii), kochia (Bassia scoparia), and smooth brome (Bromus inermis). Other herbaceous species in these areas included showy milkweed (Asclepias speciosa), Canada thistle (Cirsium orvense), and common sunflower (Helianthus annuus). Scattered trees and shrubs (generally less than 20 feet tall) at the periphery of herbaceous areas included plains cottonwood (Populus deltoides), rabbitbrush (Ericameria nauseosa), coyote willow (Salix exigua), and crack willow (Salix fragilis). Wetland vegetation was observed during the site visit along a drainage ditch that runs along the eastern boundary of the property (Figure 2). Wetlands comprised approximately I percent of the study area and had vegetative cover of 100 percent. They are further described in detail below. There is also a concrete -lined ditch present on the property. The Cache la Poudre River runs along the southern edge of the property but does not intersect the study area. Due to the current use of the site for agriculture, the.natural vegetation, soils, and hydrology have likely been altered by filling, grading, and improvement activities. Soils The general soil types encountered while completing wetland sampling points were clay loams and sandy clay loams. There are six soil types mapped within the study area (USDA, 2022; Table 1). The United States Department of Agriculture (USDA) soil map for the study area has been included as an attachment to this memorandum.

Other wildlife species that could be expected occur in the study area include mule deer (Odocoileus hemionus), raccoon (Procyon lotor), red fox (Vulpes vu/pes), skunk (Mephitis mephitis), American badger (Taxidea taxus), and coyote (Canis latrans). Seasonal wildlife ranges mapped in the study area include winter range for mule deer and white-tailed deer, and winter concentration and production for Wild Turkey (Meleagris gallopavo) and Canada Goose (Branta canadensis) (CPW, 2022). Federally Listed Species Based on a review of the USFWS online Information for Planning and Consultation (IPaC) system, there are nine federally listed species with the potential to occur in, or be impacted by, a project in this location (USFWS, 2022). Four of these species are included because they occur downstream of the study area along the Platte and/or Missouri Rivers and could be impacted by projects that result in water depletions to their tributary, the South Platte River. These species include the pallid sturgeon (Scophirhynchus albus), Piping Plover (Charadrius melodus), Whooping Crane (Grus americana), and western prairie fringed orchid (Platanthera praeclara). Impacts to these species would be covered under Colorado's Depletions Plan as part of the Platte River Recovery Implementation Program (PRRIP, 2015). Therefore, no further action regarding these four downstream species is required. The habitat and distribution of each of the remaining species was reviewed, and the potential for occurrence for each species was assigned based on the conditions in the study area (Table 2). The monarch butterfly (candidate for federal listing) is found within a variety of habitats that feature their obligate larval host plant, milkweed. Showy milkweed was noted in the study area. Therefore, the study area does include habitat for the monarch butterfly. As the monarch butterfly is not currently federally listed, no consultation or mitigation is required for this species.

Notes: FT = federally listed as threatened FE = federally listed as endangered FC = candidate for federal listing 1 — Based on a review of information from NatureServe Explorer online (NatureServe, 2021) and CPW Species Activity Mapping (CPW, 2022). State -listed Species Based on a review of the CPW Species Activity Mapping data and the Colorado Natural Heritage Program (CNHP) Tracking List, there are state listed species and state species of special concern with the potential to be impacted by work occurring in the study area (CPW, 2020; CNHP, 2019). These species are the Bald Eagle, Burrowing Owl (Athene cunicularia), black -tailed prairie dog, and northern leopard frog (Lithobates pipiens). The Bald Eagle is a state species of special concern (not a statutory category) and is also protected by the federal Bald and Golden Eagle Protection Act (BGEPA) and the Migratory Bird Treaty Act (MBTA). The study area is located within Bald Eagle mapped winter range and foraging habitat (CPW, 2022). Further, there is a CPW-mapped winter roost located approximately 1/8 mile east of the study area and Bald Eagles were noted roosting in and near the study area during the January 21, 2022 site visit (Figure 2; Photographic Log, Photos 3 and 4). Black -tailed prairie dogs are a state species of special concern. Black -tailed prairie dog burrows were noted in the study area at the time of the site visit (Figure 2, Photographic Log, Photos 5 and 6). No activity was noted Biological Resources Technical Memorandum Biological Resources Evaluation for the Great Western Phase I Lease Area Pinyon at this colony during the January 21, 2022 site visit; however, during the June 2022, this colony was noted to be active (Photographic Log, Photo 7). The Burrowing Owl is a state threatened species and is also protected by the MBTA. The prairie dog burrows in the study area may provide suitable habitat for Burrowing Owls. Burrowing Owls were not observed during the site visits. The northern leopard frog is a state species of special concern and there is suitable habitat for this species in the study area. Habitat for this species typically consists of permanent water bodies with rooted aquatic vegetation. In summer, they commonly inhabit wet meadows and fields. Migratory Birds The MBTA protects migratory birds, their nests, and their eggs (except for pigeons, starlings, and certain other species). In Colorado, most nesting and rearing activities occur between April I and August 31. These dates are guidelines and nesting birds are protected regardless of the time of year. Further, CPW recommends seasonal restrictions and buffer zones for active nests of several species of Colorado raptors that range from 0.25 mile to 0.5 mile, depending on the species (CPW, 2020). The nesting season for most Colorado raptors occurs between February 15 and August 3 I, but eagles and certain other species can nest as early as January. There are trees and upland grassy habitats throughout the study area that could serve as nesting habitat for small migratory birds. Additionally, the trees along the Cache la Poudre River and other tall trees in the area could serve as habitat for nesting raptors. One potential raptor nest was noted during the January 2I, 2022 site visit in a tree near the river, approximately 100 yards east of the study area (Figure 2; Photographic Log, Photo 8). This nest could not be located during the June 2022 site visit due to foliage, but a Swaipson's Hawk (Buteo swainsoni) was noted perched in the nest tree. Waters of the U.S. Two ditches and one wetland were mapped in the study area (Figure 2). Pinyon has provided an initial assessment of the potential jurisdictional status of these waters and wetlands; however, only the USACE has the authority to determine jurisdiction. Unnamed Ditch I Unnamed Ditch I runs along the eastern edge of the study area (Figure 2; Photographic Log, Photo 9). There are wetlands (Wetland I) associated with this feature (Figure 2; Photographic Log, Photos 9 and 10). The OHWM of this feature is intermittent. The OHWM begins at the northern end of the study area and does not continue further to the north. The OHWM disappears at the northern edge of Wetland I and begins again near the southern edge of Wetland 1, eventually terminating at the Cache la Poudre River. There was no water in this feature during either of the site visits. This ditch appears to have been created to convey excess irrigation water into the Cache la Poudre River; however, it appears that water no longer flows into the Cache la Poudre River and rather, excess water from irrigation pools in WL-I. Because this ditch and associated wetlands are human made features created in an upland setting and would revert to uplands if irrigation activities were to cease, these features may not be considered jurisdictional. Unnamed Ditch 2 Unnamed Ditch 2 is a concrete lined ditch that appears to be a relic from past agricultural activities (Figure 2; Photographic Log, Photo I I ). Flowing water was not present in this feature during the either of the site visits and this feature does not appear to have received water recently as it was filled with dirt and debris. Unnamed Biological Resources Technical Memorandum Biological Resources Evaluation for the Great Western Phase I Lease Area Pinyon ❑re��a�t �rc Ditch 2 terminates at Unnamed Ditch I . Because this ditch appears to be a human made relic of past agricultural activities, it may not be considered jurisdictional. Conclusions and Recommendations Pinyon biologist Mark Fletcher visited the site on January 21 and June 16, 2022, to assess the study area for biological resources, including general wildlife; state and federally listed threatened, endangered, and special concern species; raptors and other migratory birds; and WOTUS, including wetlands. Potential impacts to general wildlife from project construction are expected to be minor, as most of the area is currently cropland that does not provide high quality wildlife habitat. This project will create a pit that will be used for water storage. The current agricultural, grassland, and wetland habitat will shift to an open water habitat. The project has been designed to avoid impacts to the Cache La Poudre River and associated riparian area. Because the study area is situated next to an existing mine site, increased habitat fragmentation due to project construction is not expected. Further, the project footprint is relatively small compared to the surrounding open areas. Based on the location of the study area and available habitat, development of the study area is not anticipated to impact federally listed species. There are several state -listed or special concern species with the potential to occur in or be impacted by development of the study area. Pinyon recommends the following related to state -listed and special concern species: There is a CPW-mapped Bald Eagle winter roost near the property and several Bald Eagles were noted roosting in and near the project area during the site visit. Because there is another mine site closer to the mapped roost, Bald Eagles in the area may be habituated to disturbances associated with mining activities and the area may be considered a Highly Developed Area. Determination of whether or not a roost is within a Highly Developed Area should be done in coordination with CPW (CPW, 2020). For Highly Developed Areas, CPW recommends a seasonal (November 15 — March 15) buffer of 660 feet (I/8 -mile) for disturbances not in direct line of sight and a buffer of 1/4 -mile for disturbances in direct line of sight. If impacts on or near the prairie dog burrows are. expected, Burrowing Owl surveys should be completed prior to construction activities that are scheduled to take place from March 15 to October 31. Surveys should be conducted in accordance with the CPW Recommended Survey Protocol and Actions to Protect Nesting Burrowing Owls (CPW, 2021). If active Burrowing Owl nests are found during the surveys, work should be avoided within 660 feet of the active nest (CPW, 2020). There is habitat for the northern leopard frog in the study area. As a special concern species, the northern leopard frog does not have any regulatory protections, and no mitigation is required for this species. Best Management Practices (BMPs) and avoidance measures for waters and wetlands will also benefit this species. Due to the potential for MBTA constraints, if work is to occur during the nesting season for small migratory birds (April I through August 31), Pinyon recommends that the project conduct surveys for nests prior to ground disturbance (e.g., clearing and grubbing activities). Work should be avoided within 50 feet of active nests of small migratory birds. If work is to occur during the nesting season for Colorado raptors, Pinyon recommends conducting raptor nest surveys within 0.5 mile of the study area (CPW, 2020). The nesting season for most Colorado raptors occurs between February 15 and August 31, but eagles and certain other species can nest as early as January. If active raptor nests are noted within the CPW-recommended buffer for that species, coordination with CPW and/or USFWS may be necessary. Biological Resources Technical Memorandum Biological Resources Evaluation for the Great Western Phase I Lease Area Pinyin` Two ditches and one wetland area were mapped in the study area (Figure 2). Pinyon has provided a preliminary assessment of the potential jurisdictional status of these waters and wetlands; however, only the USACE has the authority to determine jurisdiction. Unnamed Ditch I and the associated wetlands, and Unnamed Ditch 2, may not be jurisdictional. If the project is unable to avoid these features, Martin Marietta could proceed by submitting a jurisdictional determination (JD) request to the U.S. Army Corps of Engineers.

BIOLOGICAL RESOURCES Great Western Phase I Lease Area Weld County, Colorado Drawn By: MJS Reviewed By: MRF Figure: 2 Date: 7/15/2022 Windsor East Mine, Exhibit I — Soils Information September 2022 EXHIBIT I - SOILS INFORMATION A soils map was generated using the Natural Resource Conservation Service's (NRCS) Web Soil Survey (httos://websoilsurvey.sc.egov.usda.gov/Aoo/WebSoilSurvey.asoo). The Web Soil Survey catalogs soil data and information produced by the National Cooperative Soil Survey. Appendix I-1 presents the map and dominant soil overview for the Windsor East Mine. The Soil Survey of Weld County Area, Colorado published in 1980 by the USDA, Soil Conservation Service was used to find characteristics of the soil at the site. The following explains, in detail, the various soil types found on the Windsor East site but most of the vegetation described does not exist because the ground has been farmed and harvested annually. Aquolls and Aquents, gravelly substratum This nearly level map unit is on bottom lands and flood plains of all the major streams in the survey area. Aquolls, which have a dark colored surface layer, make up about 60 percent of the unit. Aquents, which have a lighter colored surface layer, make up about 35 percent. About 5 percent is Aquepts and Bankard sandy loam. These are deep, poorly drained soils that formed in recent alluvium. No one pedon is typical. Commonly, the soils have a mottled, mildly alkaline to moderately alkaline loamy or clayey surface layer and underlying material and are underlain by sand and gravel and gravel within 48 inches. In places they have a gleyed layer in the underlying material. Most of the acreage is subject to flooding. The water table is at or near the surface early in spring and recedes to as deep as 48 inches late in fall in some years. These soils are used for rangeland and wildlife habitat. Some small areas have been reclaimed by major drainage and leveling and are used for irrigated crops. The potential native vegetation is dominated by alkali sacaton, switchgrass, and westem wheatgrass. Saltgrass, sedge, rush, and alkali bluegrass are also prominent. Potential production ranges from 3,000 pounds per acre in favorable years to 2,000 pounds in unfavorable years. As range condition deteriorates, the switchgrass, alkali sacaton, and western wheatgrass decreases and saltgrass, sedge, and rush increase. Ellicott -Ellicott sandy skeletal complex Ellicott soils are deep, excessively drained soils. They are formed from noncalcareous, stratified sand alluvium. Typical surface layers consist of grayish brown loamy coarse sand ranging from 2 to 8 inches thick, underlain by light brownish gray coarse sand stratified with layers of sand to 60 inches. These soils have rapid permeability and have a rare frequency of flooding. Runoff is classified as negligible. Colombo clay loam, 0 to 1 percent slopes and 1 to 3 percent slopes This is a deep, well drained soil on flood plans and terraces at elevations of 4,600 to 4,780 feet. It formed in stratified calcareous alluvium. Included in mapping are small areas of soils that have a loam surface layer and some small leveled areas. Typically the surface layer of this Colombo soil is dark grayish brown clay loam about 14 inches thick. The upper 7 inches of the underlying material is pale brown stratified clay loam and loam. The lower part to a depth of 60 inches is very pale brown loam stratified with thin lenses of fine sand, medium sand, and clay loam. Permeability is moderate. Available water capacity is high. The effective rooting depth is 60 inches or more. Surface runoff is slow to medium, and the erosion hazard is low. OTETRA TECH Page 112 Windsor East Mine, Exhibit I — Soils Information September2022 Kim loam, 1 to 3 percent slopes This is a deep, well drained soil on smooth plains and alluvial fans at elevations of 4,900 to 5,250 feet. It formed in mixed eolian deposit and parent sediment from a wide variety of bedrock. Included in mapping are small areas of soils that have loamy sand underlying material. Typically the surface layer is brown and pale brown loam about 12 inches thick. The upper 28 inches of the underlying material is pale brown loam. The lower part to a depth of 60 inches is pale brown fine sandy loam. Permeability is moderate. Available water capacity is high. The effective rooting depth is 60 inches or more. Surface runoff is medium, and the erosion hazard is low. Nunn loam, 0 to 1 percent slopes This is a deep, well drained soil on terraces at elevations of 4,550 to 5,000 feet. It formed in mixed alluvium. Included in mapping are small, long and narrow areas of sand and gravel deposits and small areas of soil that are subject to occasional flooding. Some small leveled areas are also included. Typically the surface layer of this Nunn soil is grayish brown loam about 12 inches thick. The subsoil is light brownish gray clay loam about 12 inches thick. The upper part of the substratum is light brownish gray clay loam. The lower part to a depth of 60 inches is brown sandy loam. Permeability is moderately slow. Available water capacity is high. The effective rooting depth is 60 inches or more. Surface runoff is slow, and the erosion hazard is low.

Habitat types include grasslands (irrigated cropland) and a non jurisdictional wetland area on the east side of the site. The Cache la Poudre River is directly south of Windsor East and its floodplain reaches into the southern portion of the site. 2.0 PRESENT VEGETATION TYPES The Windsor East Mine site is dominated by a monoculture of corn (Zea sp.), covering approximately 80 percent of the site. The perimeter of the mine site (19% of the site) is an upland habitat with a mixture of native and non- native herbaceous species including western wheatgrass (Pascopyrum smithii), kochia (Bassia scoparia), and smooth brome (Bromus inermis). Other herbaceous species in these areas included showy milkweed (Asclepias speciosa), Canada thistle (Cirsium arvense), and common sunflower (Helianthus annuus). Scattered trees and shrubs (generally less than 20 feet tall) at the periphery of herbaceous areas included plains cottonwood (Populus deltoides), rabbitbrush (Ericameria nauseosa), coyote willow (Salix exigua), and crack willow (Salix fragilis). Approximately 1% of the property contains a wetland area on the east edge along a drainage ditch. The US Army Corps of Engineers has determined this is non jurisdictional waters. See attached letter as Exhibit J-1. 3.0 RELATIONSHIP OF PRESENT VEGETATION TO SOIL TYPES The Soil Survey of Weld Courtly Area, Colorado published in 1980 by the USDA, Soil Conservation Service was used to identify soils at the site. The soil series types and their relationship Nth the vegetation types within the project area include: Irrigated Croplands: Aquolls and Aquents, gravelly substratum (Map unit 3) - These are found near the eastem and southem border of the site. Aquolls and Aquents are deep, poorly drained soils that are formed in recent alluvium. No one pedon is typical. Soils typically have a mottled, mildly alkaline to moderately alkaline loamy or clayey surface layer and are layer of sand and gravel to 48 inches. The water table is at or near the surface in spring and during peak irrigation season. Thus, these soils are subjected to excessive runoff. Ellicott -Ellicott sandy -skeletal complex, 0 — 3 percent (map unit 10) — These soils are found in a small section along the eastern border. Ellicott soils are deep, excessively drained soils. They are formed from noncalcareous, stratified sand alluvium. Typical surface layers consist of grayish brown loamy coarse sand ranging from 2 to 8 inches thick, underlain by light brownish gray coarse sand stratified with layers of sand to 60 inches. These soils have rapid permeability and have a rare frequency of flooding. Runoff is classified as negligible. Colombo Clay Loam, 0 - 1 percent and 1 — 3 percent (map unit 19 and 20) — These soils are in the center of the site. Colombo Clay Loam soils are deep, well drained soils on flood plains and terraces, formed in stratified calcareous alluvium. Typical surface layers consist of dark grayish brown clay loam about 14 inches thick underlain by a layer of very pale brown loam stratified with lenses of fine sand, medium sand and clay loam to 60 inches. Colombo clay loam soils have moderate permeability and high available water capacity. Surface runoff is low and erosion hazard is low. OTETRA TECH Page 112 Windsor East Mine, Exhibit J — Vegetation Information September2022 Kim Loam, 1 - 3 percent (map unit 32) - A section of Kim Loam soils occurs in the northwest corner of the property. These are deep, well drained soils on smooth plains and alluvial fans. These soils formed in mixed eolian deposits derived from sedimentary rock. A typical surface layer is brown and pale brown loam about 12 inches thick, underlain by pale brown loam and pale brown fine sandy loam to 60 inches. Kim loam soils have moderate permeability and have high available water capacity. Surface runoff is medium and erosion hazard is low. Nunn Clay Loam, 0 -1 percent (map unit 39) - This soil type occurs on the southwest side of the site. These are deep, well drained soils on terraces. They are formed in mixed alluvium. A typical surface layer is grayish brown clay loam about 12 inches thick underlain by light brownish gray clay loam and brown sandy loam to 60 inches. Kim loam soils have moderately slow permeability and high available water capacity. Surface runoff is slow and erosions hazard is low. 4.0 ESTIMATE OF AVERAGE ANNUAL PRODUCTION This section is not applicable for the Windsor East Mine site because reclaimed areas will not be used for agriculture.

We received a request for an Approved Jurisdictional Determination (JD) for the above project area. The project area has been reviewed in accordance with Section 404 of the Clean Water Act under which the U.S. Army Corps of Engineers regulates the discharge of dredged and fill material, and any excavation activity associated with a dredge and fill project in waters of the United States. At your request, a JD has been prepared for the subject area. Based on a review of available documentation, we have determined that the resources labeled "Unnamed Ditch 1, Unnamed Ditch 2, and Wetland 1 are not waters of the United States. The attached JD form provides rationale for why no resources on the property meet the definition of waters of the United States. Therefore, a Department of the Army permit is • not required for the discharge of fill material into this site under Section 404. The JD is attached to this letter. If you are not in agreement with the JD decision, you may request an administrative appeal under regulation 33 CFR 331, by using the attached Appeal Form and Administrative Appeal Process form. The request for appeal must be received within 60 days from the date of this letter. It is not necessary to submit a Request for Appeal if you do not object to the JD. This JD is valid for a period of five years from the date of this letter, unless new information warrants revisions of the JDs before the expiration date, or unless the Corps has identified, after a possible public notice and comment, that specific geographic areas with rapidly changing environmental conditions merit re -verification on a more frequent basis. -2 - If there are any questions please feel free to contact Daniel Ishmael at (720) 948- 3266 or by e-mail at Daniel.C.lshmael@usace.army.mil, and reference Corps File No. NWO-2022-01585-DEN.

TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non -navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section 111.8.1 for the tributary, Section II1.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.C below. 1.

Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: 1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: . 2.

El Other (explain, if not covered above): Reference is made to the November 13, 1986 Federal Register (Page 41217), Part 328 (b). Artificially irrigated areas which would revert to upland if the irrigation ceased. In this case, Wetland 1 appears to have formed from bank failure associated with an irrigation ditch with additional input from sheet flow runoff associated with crop irrigation. If agricultural activities were to cease, the wetland would no longer exist. The wetland was not present prior to ditch construction. As such, this aquatic resource is not considered jurisdictional. Reference is made to the November 13, 1986, Federal Register (Page 41217), Part 328.3(a) Non -tidal drainage and irrigation ditches excavated on dry land. Unnamed Ditch 1 and Unnamed Ditch 2 appear to be irrigation ditches associated with excess agricultural runoff. Unnamed Ditch 1 and Unnamed Ditch 2 do not appear to carry relatively permanent flows to the Cache La Poudre River. As such, these aquatic resources are also not considered jurisdictional. The Corps reserves the right on a case -by -case basis to determine that a particular waterbody within these categories of waters is a water of the United States. Provide acreage estimates for non -jurisdictional waters in the review area, where the sole potential basis of jurisdiction is the MBR factors (i.e., presence of migratory birds, presence of endangered species, use of water for irrigated agriculture), using best professional judgment (check all that apply): Non -wetland waters (i.e., rivers, streams): linear feet width (ft).

ADDITIONAL COMMENTS TO SUPPORT JD: 7 Windsor East Mine, Exhibit K — Climate Information September 2022 EXHIBIT K — CLIMATE INFORMATION The subject site area has a high plain, continental climate. With the mountains to the west, variations in temperature are wide. In the high plains area, rainfall is light and humidity is low. The average frost -free period is 172 days. Annual average precipitation is about 14 inches. In the eastern high plains area, the climate is modified considerably from that expected of a typical high plain because of the nearby mountains to the west. The winds characteristic of the plains are reduced somewhat by the shielding effect of the mountains. Climate data for the site is assumed to be similar to that of the weather station at Greeley UNC, Colorado. The Western Regional Climate Center tracks temperature extremes and precipitation data for this station.

OTETRA TECH Page 1l1 Windsor East Mine, Exhibit L — Reclamation Costs September 2022 EXHIBIT L - RECLAMATION COSTS During the life of mine, 150 acres will be disturbed by the mining activities and approximately 54.7 acres of that will be water surface once reclamation is completed leaving 95.6 acres to be topsoiled and seeded. This site will be mined and reclaimed concurrently to limit the number of times that overburden is handled. The spreadsheet below represents the estimated cost for the Division to reclaim the Windsor East Mine, based on the point in time in the mining schedule where reclamation cost will be the highest. This will occur when Cell A is lined, Cell C is mined out but not lined, Cell B has had the topsoil removed and Cell D is mined out. At this point there will be an estimated 117 acres of disturbance.
