The geographic coordinates of the main entrance area are 40° 00' 40.82" North, 104° 50' 21.43" West. Sand and gravel will be the primary product produced from a small portion of the Wattenberg Lakes site. The principal intended use for the sand and gravel is for construction aggregates. Agricultural and mining uses surround the property, with residential uses extending farther from the site including the community of Wattenberg north of the property. The majority of the site is immediately west of the South Platte River between Weld County Road (WCR) 2 and WCR 6. Although a small northeastern section of the property straddles the South Platte River, the mining operation will not disturb the river. Mining was completed previously for most of the property, with only a small amount of additional mining planned (6.2 acres) to create the area required to complete Pond 1 (also known as the Struck Pond). The primary changes in the current DRMS permit amendment mining plan compared with the 2004 DRMS permit mining plan include the following (changes to the reclamation plan are noted in Exhibit E): • Mining has been completed in most of the permit area, with only a minimal amount of mining planned in two small areas in the Pond 1 (Struck Pond) area; Area 1 (see Exhibit C) was not previously included in the 2004 mining plan. • The Huett Seep/Ditch was re-routed immediately east of Pond 3 as part of the activities permitted in 2004. • A decreased area of mining occurred in the west boundary area of Pond 3, resulting in a straightened western pond boundary and a decrease in the disturbance during mining compared with the 2004 permit, The total DRMS permit amendment area covers 420.8 acres. The permit boundary and affected area are the same for this amendment. Within the site, 6.2 acres of the land will be mined as shown for Area 1 (3.2 acres) and Area 2 (3.0 acres) in Exhibit C, Map C-1; the remaining areas will be used for temporary earthwork and other material movement (minor grading) as part of reclamation activities. Area 1 and Area 2 are planned for mining concurrently. In June and August 2022, a survey was conducted within the permit area for wetlands and other waters of the U.S.; the delineation report is included in the vegetation exhibit (Attachment J-1) and wetlands are shown in Exhibit C, Map C-1. Holcim is working with the U.S. Army Corps of Engineers (USACE) to amend an existing permit to cover the wetland mitigation required to satisfy USACE 404 requirements. Please see Exhibit J for vegetation information. The proposed plan does not include mining in areas with existing wetlands. The saleable aggregate material to be removed from Area 1 and Area 2 will amount to approximately 158,000 cubic yards (221,000 tons at 1.4 ton/cy), based on exploratory logs from the previous investigation for adjacent Pond 3. The overburden and growth medium materials excavated as part of the mining operation, along with overburden previously placed in the west half of Pond 1 (Struck Pond), will total approximately 900,000 cubic yards. Overburden and growth medium will be stockpiled for use as backfill and reclamation within the permit area; excess overburden will be hauled off site for other uses. Based on routine groundwater elevation monitoring in the Wattenberg Lakes site, Area 1 and Area 2 groundwater is typically expected at approximately 2 ft below ground surface but can be less than 1 ft during seasonal highs. Additional information on groundwater at the site is presented in Exhibit G (Water Information). TETRA TECH Page 1(4 Wattenberg Lakes Amendment, Exhibit D — Mining Plan May 2023 2.0 PHASING AND METHODS OF MINING 2.1 Phasing Holcim anticipates conducting operations under this DRMS permit amendment in three phases for a total duration of 18 months, with mining of Area 1 and Area 2 planned for only 2 months of that duration and the other activities as part of reclamation (discussed in Exhibit E). The three phases are: 1. Phase 1 — Concurrent activities (10 months) a. Grade/fill to achieve side slopes of 3H:1V (horizontal:vertical) b. Build up south edge of existing Pond 1 on south side to create 40 -ft buffer from top of pond slope to county road c. Mine areas 1 and 2 d. Place fill in other parts of the site to achieve reclamation grades 2. Phase 2 — Construct slurry wall and perimeter drain (2 months) 3. Phase 3 — General earthwork on western side of footprint (excess fill to be used for backfill as needed in other parts of the site) (6 months) In Phase 1, prior to or while initiating mining in Area 1 and Area 2, the Pond 1 side slopes will be graded to the base of the pond at a 3H:1V slope. Also, excess fill from the western portion of the Pond 1 footprint area will be used to build up the southern perimeter of Pond 1 to create a 40 -ft offset from the county road to the top of the pond embankment. Area 1 and Area 2 will be mined and excess fill (placed previously in the western part of the footprint) removed and placed in the cottonwood replacement area or other areas where fill is required to achieve the reclamation grades. Also, in areas outside Area 1 and Area 2, minor earthmoving and grading will take place to establish reclamation grades for wetland establishment, cottonwood replacement, and other reclaimed uses as presented in Exhibits E and F. In Phase 2, the slurry wall and perimeter drain will be constructed around the perimeter of the final footprint of Pond 1. Design specifications for the slurry walls and quality control procedures used during construction will ensure that the reservoirs meet State Engineer's Office (SEO) performance standards. Specific specifications and quality control procedures will be provided to the Division for review prior to construction of the slurry walls. After construction of these reclamation features, Phase 3 general earthwork will take place on the western side of the Pond 1 area and excess fill not used in this area will be used to achieve reclamation grades in other parts of the site. 2.2 Equipment The aggregate material will be recovered using equipment and facilities typical for sand and gravel mining operations. The equipment and facilities may include, but not be limited to, a conveyor system from the mining area to the Holcim's Platte Valley Plant; additional, portable, temporary processing equipment on an as needed basis for screening, crushing, and washing; earth -moving equipment including dozers, loaders, scrapers, excavators, dragline, dredge, compactors, and field conveyors; and an employee/storage trailer and fueling/lubricating station. Dewatering pumps and generators and watering trucks will be also used as needed. 2.3 Mining Process The typical mining process for Area 1 and Area 2 will involve stripping growth medium and overburden with scrapers, to expose the aggregate product below, and stockpiling these materials in the temporary stockpile areas identified in Exhibit C. Mining of the aggregate will progress down to the underlying claystone bedrock. The bedrock material is rippable and, when necessary, will be excavated and used for reclamation. Overburden found on the site will be used to fill in the reclamation slopes and for minor grading and fill needed in other areas as part of reclamation. Overburden and growth medium reserved for reclamation will be vegetated and stabilized in accordance with Rule 3.1.9(1). All soil and overburden material will be used for reclamation, so long-term stockpiling of these materials is not anticipated. The mining areas will be reclaimed using soil, OTETRA TECH Page 2)4 Wattenberg Lakes Amendment, Exhibit D — Mining Plan May 2023 overburden, process fines, and other inert materials from on -site. If materials from off -site are used, Holcim will provide the Division with the appropriate notices and affidavit in accordance with Rule 3.1.5(9). During mining and prior to reclamation, the mine walls will be nearly vertical at a 0.5H:1V slope. The aggregate material will be temporarily stockpiled or placed directly onto a conveyor system for transport. The conveyor system will transport the material to be processed at an existing DRMS permitted mining site (Permit Number M- 89-120) immediately east of the property (Holcim's Platte Valley Plant). The conveyor will cross the South Platte River within the permit boundary before entering the adjacent mining site as illustrated on the Pre-Mining/Mining Plan Map (Exhibit C). Alternatively, if needed, a limited amount of material may be processed on -site with portable and temporary screening, crushing, and/or washing equipment. Once backfilling and grading has been completed in an area, the top of the slope and the side slopes above the anticipated reservoir water level will be seeded as soon as practicable (in first available seeding season). Prior to and during removal of the materials in Area 1 and Area 2, a dewatering system will be operated using the current pump system that is on site. If additional capacity is needed, the pump system will be upgraded. Dewatering trenches will be excavated around the perimeter of each pond and pumps will be used to remove the water that drains from the deposit and surrounding alluvium into the trench. The water removed during dewatering will be used for dust control at the site or piped to the nearby unlined Stillwater Ski Lake (owned by Holcim) or to permitted outfall 8 at the South Platte River. Stormwater that falls within the mine areas will drain internally and will also be removed through dewatering operations. There will not be uncontrolled releases of surface water and sediment from mining areas. Water associated with the site will be used for dust control operations during use of the roads and for stockpiles and berms. The water used to limit dust emissions will be applied using a water truck with capacity of 2,500 or 4,000 gallons. As noted above, water for dust control will come from the dewatering process. No explosives will be used to mine the site. 3.0 STOCKPILES Growth medium and overburden in the Area 1 and Area 2 mining area will be stripped with scrapers or a dozer and placed separately in temporary stockpiles to the north and west of the mining area. The growth medium will be segregated and stored separately (see Exhibit C-1 map) to the north of Pond 1 and the overburden material will be temporarily stored to the north and west of the mining area, as required by Rule 3.1.9(1). The stockpiles will have an average height of 8 feet tall; they will have maximum 3H:1V side slopes. The overburden stockpiles will be used for backfilling and reclamation where needed on the site. No excess overburden is anticipated for this site. The growth medium stockpile will be protected from wind and water erosion by vegetative cover (see the Seed Mix for Upland Areas found in Exhibit E). Also, overburden stockpiles reserved for reclamation will be vegetated and stabilized in accordance with Rule 3.1.9(1). 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. 4.0 COMMODITIES TO BE MINED The primary commodity to be mined will be aggregate. Holcim will supply local, county, and state governments, as well as private industry with aggregate from this facility. 5.0 OFFSETS The mining area will be subject to setbacks to prevent disturbance of road and utility rights -of -way and undisturbed wetland areas. Holcim will maintain a 200 -foot minimum setback from the South Platte River. In the Pond 1 area, the limit of mining will be at least 40 feet from the proposed permit boundary or county roads (see the Pre-Mining/Mining Plan Map, Exhibit C). In all other areas, a minimum 25 -foot setback will be maintained from OTETRA TECH Page 3 l 4 Wattenberg Lakes Amendment, Exhibit D — Mining Plan May 2023 the permit boundary. Setbacks from man-made structures not owned by Holcim or the City of Westminster will be established at twice the pit depth unless an agreement is obtained from the property owner or engineering slope stability analyses performed. Items owned by Holcim or the City of Westminster located within the proposed permit boundary, such as roads, fences, water wells and associated pumps, and structures including a house and outbuildings, may be removed or relocated during the mining process. There are additional structures on the site not owned by Holcim or the City of Westminster (see the Pre-Mining/Mining Plan Map, Exhibit C). The structures in the overall site include oil and gas wells and associated facilities and power transmission lines. Mining and reclamation activities will avoid these structures (see Exhibit S, Permanent Man -Made Structures within 200 Feet of the Affected Land). Prior to mining under the 2004 permit, there were oil and gas wells and flowlines in parts of the site, but none of these remain in the small areas to be mined and where grading for reclamation is planned. Previously, a well located within the Pond 1 footprint (within mining Area 1) was plugged and abandoned, thus allowing the full area of Pond 1 to be constructed for water storage. 6.0 ROADS AND CONVEYORS Preparation for mining will include constructing 15 -ft -wide gravel access roads as needed. These gravel roads are included in the permitted acreage and will be removed and reclaimed after mining. All the aggregate material will be transported via conveyor from the mining area to Holcim's Platte Valley Plant to the east for processing. The conveyor is set on concrete blocks or frames. The main conveyor line comes from the south and currently crosses the Pond 1 area (will be relocated to go around the west side of Pond 1 area), then continues along the north side of Pond 1 following its current alignment to the east side of the permit area. The conveyor will continue to be operated for future permitted mining in areas to the south of the Wattenberg permit area. A 10.5 -ft 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. OTETRA TECH Page 414 Wattenberg Lakes Amendment, Exhibit E — Reclamation Plan May 2023 EXHIBIT E - RECLAMATION PLAN 1.0 GENERAL Area 1 and Area 2 will be mined and reclaimed as part of the development of Pond 1 (Struck Pond) that the landowner, the City of Westminster, will own and use for water storage. Pond 3, previously reclaimed through construction of the slurry wall, will also be used by the City of Westminster for water storage; please see Technical Revision (TR) 1 for slurry wall technical specifications and construction completion report (12/18/2014), approved by DMRS (1/8/2015). Other un-reclaimed but previously mined areas within the permit boundary will also be reclaimed through backfilling, as needed, and minor grading, and establishment of plantings and ground covers to restore and enhance all areas disturbed by current or previous mining activities. The primary changes in the current DRMS permit amendment reclamation plan compared with the 2004 DRMS permit reclamation plan include the following (changes to the mining plan are noted in Exhibit D): Pond 1, now called the Struck Pond, has an expanded footprint to the west of the originally planned pond in the area previously identified for wetland mitigation area and slightly north as well; this adjustment to the north results in an addition to the affected area covered under the 2004 permit, thus requiring this amendment. • Pond 2, identified in 2004 in the west-northwest part of the permit area, now is planned for wetland mitigation with part of the area to remain dedicated for access to two remaining producing oil wells. The Pond 3 boundary along the west side was straightened during mining and a slurry wall was constructed around the revised pond perimeter. Some of the previously identified wetland mitigation areas are changed in location to accommodate revised plans for future use of the site. The wetland planting list is updated based on recent information including a wetland survey. Key considerations for preparing this reclamation plan include the following: All wetlands on the site were located and delineated in June and August 2022. Existing wetlands will be avoided to the extent feasible during mining, earthmoving, and reclamation activities. Also, wetlands will be created in the identified wetland mitigation areas. Maintenance activities on the site will also include a comprehensive Weed Management Plan to limit the spread of invasive species into the riparian areas and wetlands. The Pond 1 (Struck Pond) reservoir will be isolated from the surrounding alluvial aquifer by constructing a slurry wall; a perimeter drain will also be constructed to minimize impacts of the slurry wall on groundwater flow through this area. Multiple groundwater monitoring wells are located within the permit area and will continue to be monitored before, during, and after the mining and reclamation are completed. 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. See Exhibit G for more information. 2.0 RECLAMATION OVERVIEW • As discussed in the Mining Plan (Exhibit D), Holcim anticipates conducting operations under this DRMS permit amendment in three phases for a total duration of 18 months, with mining of Area 1 and Area 2 planned for only 2 months of that duration (in Phase 1 only). The reclamation activities in these threephases will occur concurrently (for Phase 1) or within nine months after completion of Phase 1 (for Phases 2 and 3). Reclamation will focus on constructing the pond liner/slurry wall and also general backfilling and earthwork leading up to planting and seeding to establish vegetation in the disturbed areas. Reclamation, including regrading and seeding, will be completed within 2 to 5 years following initiation of these remaining reclamation activities. The three phases are: 1. Phase 1 - Concurrent activities (10 months) a. Grade/fill to achieve side slopes of 3:1 OTETRA TECH Page 116 Wattenberg Lakes Amendment, Exhibit E — Reclamation Plan May 2023 b. Build up south edge of existing Pond 1 on south side to create 40 -ft buffer from top of pond slope to county road c. Mine areas 1 and 2 d. Place fill in other parts of the site to achieve reclamation grades 2. Phase 2 — Construct slurry wall and perimeter drain (2 months) 3. Phase 3 — General earthwork on western side of footprint (excess fill to be used for backfill as needed in other parts of the site) (6 months) Each area will be reclaimed using soil, overburden, process fines, and other inert materials from on -site. However, if materials from off -site are used, the applicant will provide the Division with the appropriate notices and affidavit in accordance with Rule 3.1.5(9). There will not be known toxic or hazardous materials in the backfill material. Additionally, no acid-forming or toxic materials will be used during mining and it is unlikely they will be encountered in the mining. The mining will not leave high walls on the property. There will be no auger holes, adits, or shafts left on the property. Reclamation quantities and costs are summarized in Exhibit L. 3.0 POST -MINING LAND USE The post -mining land use, as proposed in this Reclamation Plan consists of water storage ponds surrounded by wetland and upland vegetation. In this area of Weld County, mining and developed water storage are predominant land uses along the South Platte River. Therefore, the proposed post -mining land use is compatible with surrounding land uses. The area within the proposed permit boundary will consist of two reservoirs, reservoir shorelines, backfilled wetland/riparian mitigation areas, permanent access and county roads, and other reclaimed or otherwise undisturbed land. The following areas will comprise the final land use: Reclamation and Post -Mining Land Use Areas Area (acres) 176.3 Reservoirs — Ponds 1 and 3 Wetland mitigation total area 36.7 Cottonwood replacement total area 10.0 Access roads (reclaimed) 1.1 Misc. upland disturbed areas (reclaimed) 10.0 Areas that are undisturbed, previously disturbed and reclaimed, or access and county roads (permanent) 186.7 TOTAL 420.8 Some roads inside the proposed permit boundary will not be reclaimed but will remain for accessing and maintaining the reservoirs, wetland mitigation areas, and oil wells. The existing vehicle access road over the southern end of the Huett Seep/Ditch will remain. Unimproved roads around all reservoirs will also remain. Conveyor systems and bridges will be removed under reclamation planned for Tucson South and are not covered under the Wattenberg reclamation activities. Roads within the Wattenberg permit area that are not necessary for future access and other disturbed areas in the permit area will be reclaimed with vegetative cover to stabilize the soil and minimize erosion. 4.0 RECLAMATION MEASURES - MATERIAL HANDLING Site reclamation measures are illustrated in Exhibit F. Reclamation of the site will include development of two water storage reservoirs (total of 176.3 acres), wetland and cottonwood vegetation (total of 46.7 acres), and upland vegetation will be established on access roads to be reclaimed and miscellaneous disturbed areas (total of 11.1 acres). Areas not mined nor disturbed by other site operations (outside of the 2004 permit and planned activities) will not be subject to reclamation under this plan; these areas cover a total of 186.7 acres. TETRA TECH Page 216 Wattenberg Lakes Amendment, Exhibit E — Reclamation Plan May 2023 The mining and backfilling operations will create the rough topography for the Pond 1 reservoir shoreline. The backfilling will be done to provide stabilized shorelines around the reservoir and to minimize erosion. As shown in Exhibit F (Map F-1), backfilling of two existing unnamed ponded areas (from previous mining) will take place for final reclamation use for wetlands or cottonwood replacement; these areas are in the northwest and southeast corners of the permit area. Minor grading to reclamation grades will take place in all areas subject to reclamation. The backfill material will consist of native bedrock claystone and overburden and will be obtained from mining of Area 1 and Area 2 as well as fill material from previous mining that, for example, remains in the area immediately west of the mining area. Scrapers will be used to place the backfilled material. For Pond 1, using scrapers to layer the lifts at a maximum 3:1 slope ensures a stable configuration. Growth medium will be spread to a depth of approximately 6 inches over the surface of all areas to be revegetated as uplands or wetlands. 5.0 WATER STORAGE RESERVOIRS As noted above, the reclamation includes construction of the slurry wall and perimeter drain around the perimeter of the final footprint of Pond 1. Design specifications for the slurry walls and quality control procedures used during construction will ensure that the reservoirs meet State Engineer's Office (SEO) performance standards. Specific specifications and quality control procedures will be provided to the Division for review prior to construction of the slurry walls. The bottom of Pond 1 will coincide with the existing, relatively impermeable claystone bedrock. The slurry wall will also separate the pond from the surrounding alluvial aquifer. The slurry wall will be keyed into the bedrock material and extend upward through the entire length of the saturated alluvium. All reservoir slopes left by the mining operation will be reclaimed to at least 3H:1 V final grade; slopes above the post -mine high water level will be 3:1 and slopes below the post -mine high water level will be no steeper than 3:1. Reclamation of the side slopes will take place concurrent with mining of Area 1 and Area 2. Scrapers will be used to place bedrock claystone and overburden material along the reservoir perimeters to achieve the final grade. Final reclamation by capping with growth medium and re -vegetating above the expected reservoir water level will follow backfilling operations closely to minimize the amount ofdisturbance at any onetime. During reclamation activities, inlet and outlet works for Pond 1 will be installed. The inlet works will be constructed to provide water from the Brighton Ditch along the west side of the site. Outlet works will be designed and constructed by the City of Westminster, the user of the reservoir for water storage. The design specifications and plans for the facilities will be provided to the Division prior to construction. 6.0 REPLACEMENT WETLAND AND RIPARIAN AREAS Specific areas identified in Exhibit F (Map F-1) will be reclaimed forwetland mitigation (36.7 acres) or cottonwood replacement (10.0 acres). Reclamation will begin after backfilling and minor grading and placement of growth media are completed in a reclamation area. Depending on groundwater elevations, the final surface elevation of the backfilled wetland mitigation areas may be below the existing and surrounding ground elevation. Any slopes remaining will be reclaimed to a minimum 3H:1V grade. In the northwest part of the permit area, a 20 -ft setback will be included from County Road 23 '/ to the top of the 4H:1V slope that is graded down to the wetland area. All areas disturbed by mining and site reclamation activities will be revegetated as appropriate with a seed mix, depending on the type of reclamation to be completed — wetland or upland. The planned seed mixes are presented below. 7.0 SURFACE WATER AND GROUNDWATER 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. Holcim will comply with all applicable Colorado water laws and all TETRA TECH Page 316 Wattenberg Lakes Amendment, Exhibit E — Reclamation Plan May 2023 applicable Federal and State water quality laws and regulations and appropriate storm water management and erosion control to protect the adjacent South Platte River and riparian vegetation. 8.0 WILDLIFE The area covered by this reclamation plan was formerly used for mining or 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. While the reclamation plan does not propose to create wildlife habitat, all activities will be planned considering the safety and protection of wildlife on the property. Some species may be temporarily displaced by the mining and reclamation activities, but these species are expected to re-establish with no difficulty after the reclamation has been completed. The creation of the lakes and replacement wetlands may create additional opportunities for aquatic birds, mammals, and fish. 9.0 GROWTH MEDIUM Surface soils in the proposed mine and reclamation areas are predominantly Altvan loam, Aquolls and Aquents, and Dacono clay. All suitable soil material will be salvaged for use as growth medium. Up to 6 inches of surface soil on the property, where disturbance is planned, is expected to be usable as growth medium for reclamation. This layer includes the root zone of grasses and crops, which will be stripped and stockpiled separately. The growth medium will be segregated and stored separately from the overburden material as required by Rule 3.1.9(1). Sufficient growth medium will be stockpiled 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. Based on the mining and reclamation phasing and schedule, the growth medium is not expected to remain stockpiled for more than 1 to 2 years. If the stockpile remains for more than one growing season, it will be seeded with a fast-growing vegetative cover to prevent erosion. Where required for reclamation, growth medium will be placed to a depth of approximately 6 inches. 10.0 REVEGETATION As mining and backfilling operations are completed, areas for reclamation will be graded and shaped for revegetation. Runoff or excess water from adjacent areas will not be allowed to flow over slopes being graded and seeded. Following placement of growth media, seeding and planting will be performed according to NRCS recommended practices. The following revegetation procedures are anticipated but may be modified as conditions dictate: • 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 mixes and application rates in pounds of pure live seed per acre are listed below. • Weed control practices will be implemented as required. Upland Areas. For disturbed upland areas, the reclamation plan includes revegetating with appropriate seed mixes to minimize erosion and reestablish natural terrain. The grass mixture below was selected to be long lasting and regenerating. The ground surface will be fine graded prior to seeding. Reservoir side slopes below the anticipated reservoir water level will not be seeded. Upland grass seed will be planted with a drill equipped with depth bands and press wheels. The seeded areas will then be covered with straw mulch at a rate of 2,000 pounds per acre. The straw will be crimped into the soil to TETRA TECH Page 416 Wattenberg Lakes Amendment, Exhibit E — Reclamation Plan May 2023 control erosion until the grass becomes established. As an alternative, hydroseeding and hydromulching may be used to apply seed (at double the drill rate) and mulch.

The wetland mitigation areas will be planted and seeded with wetland plants at the locations shown in Exhibit F (Map F-1); cottonwood replacement areas are also shown in Map F-1. The wetland mitigation plan for the wetland areas, recently submitted to the U.S. Army Corps of Engineers (USACE) under the Clean Water Act Section 404 permit application for the Wattenberg Lakes site, is attached to this exhibit; see this document for further details.

The requirements of the wetland mitigation plan accepted by the USACE for this site will be followed under that plan which includes a commitment to manage State -listed noxious weeds in the mitigation areas. State -listed noxious weeds will be controlled, and reseeding and irrigation will occur as needed to establish self-sustaining desirable vegetation. As an example, 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.

Proposed Mitigation 8 ERO Project #22-078 ERO Resources Corporation Wattenberg Lakes Gravel Mining Compensatory Mitigation Plan Weld County, Colorado May 2023 Project Description ERO Resources Corporation (ERO), on behalf of Holcim-WCR, Inc. (Holcim), is providing the following information in support of an amendment to the Section 404 Individual Permit (IP) authorization for the Wattenberg Lakes Gravel Mining project (project) (Corps File No. NWO-2000-80189-DEN). Holcim, in coordination with the City of Westminster (City), is proposing modifications to the original design of the reservoirs and associated mitigation for the project. The gravel mining and water storage facilities in Wattenberg, Colorado (Figure 1). The gravel mining operations have been ongoing since 2005 and occur along both the east and west sides of the South Platte River. The original design of the project included construction of three reservoirs on the west side of the South Platte River post -mining operations (Figure 2). The City is proposing modifications to the reservoir design, including reducing it to two reservoirs instead of three, and installation of spillway to prevent damage from high flood events along the river (Figure 3). Due to these modifications to the design, and to provide the highest quality wetland mitigation, Holcim is proposing modifications to the wetland mitigation required by the project (Figure 4). This mitigation plan has been developed to address modifications to the project and associated wetland mitigation areas, and the unavoidable impacts to wetlands and other waters of the U.S. associated with the project following impact avoidance and minimization. Location The project area is in Sections 25 and 36, Township 1 North, Range 67 West; and Sections 30 and 31, Township 1 North, Range 66 West of the 6th Principal Meridian in Wattenberg, Weld County, Colorado (Figure 1). The UTM coordinates of the approximate center of the project area are 514393mE, 4429885mN of NAD 83 Zone 13N. The longitude/latitude of the project area is 104.831342°W/40.019051°N. The elevation of the project area is approximately 4,940 feet above sea level.

PROJECT NO. 22105 Wattenberg Lakes Gravel Mining Revised Compensatory Mitigation Plan Weld County, Colorado Compensatory Mitigation Compensatory mitigation replaces and improves permanently impacted resources. For this project, compensatory mitigation focuses on providing functions similar to or better than functions provided by the impacted wetlands. The impacts from mining activities and reservoir construction were largely to the Huett Ditch and Lupton Slough. Onsite mitigation originally and currently proposed are focused on recreating the form and function of the ditch and slough. Mitigation associated with Huett Ditch has already occurred, resulting in the successful re-establishment of a wetland channel with varied flow, gradual banks, and native vegetation. Mitigation for the Lupton Slough wetland impacts will occur in Phase Ill, Mine Area 2 (Figure 2), designated as Mitigation Area 4 on Figure 4. The goal of the proposed mitigation in this area is to recreate the functions of the previous saltgrass/wet meadow wetlands disturbed by project activities, as well as create palustrine scrub shrub and palustrine herbaceous wetlands to provide a highly diverse, highly functioning wetland that equals or exceeds the functions and values of the impacted wetlands. Four main mitigation areas would be constructed in the originally designated Phase Ill, Pond 2 Mining Area and Mining Area 2 in the northwestern portion of the project area (Figure 2 and Figure 4). Mitigation Area 1 is an existing herbaceous emergent wetland area that would be protected and connected to the other mitigation areas in the Phase Ill mining area (Figure 4). Mitigation Area 2 is proposed to be a willow scrub -shrub wetland area that would be created to provide diversity and overstory and would be east of Mitigation Area 1 (Figure 4). Mitigation Area 3 would be a saltgrass wet meadow complex with native herbaceous wetland vegetation south of Mitigation Area 1. Mitigation Area 4 would be southeast of Mitigation Area 3 and would consist of a native palustrine emergent wetland complex. Monitoring and evaluation of the subsurface hydrology and establishment of a native plant community appropriate to the area is anticipated to achieve the desired functional results, with more detailed discussion provided below on proposed approach. In addition to the proposed mitigation areas described above, the Heutt Ditch wetlands previously established would remain north and south of the proposed spillway (Figure 3). No modifications to these wetland mitigation areas are proposed and these areas will continue to be monitored as part of the overall mitigation monitoring requirements. The objectives of the mitigation plan are to mitigate in the project area at an aerial and functional compensatory mitigation ratio of no less than 1:1. Mitigation onsite is necessary to maintain a healthy watershed, provide wildlife habitat and continuity of a wildlife corridor along the South Platte River, and recreate the functions and values previously provided by the wetlands onsite. The onsite mitigation would benefit the South Platte riverscape as an integrated system of interworking parts to promote the ditches and stream channel, floodplain, terraces, riparian communities, and wetlands to all function together. The restoration of wetland and riparian vegetation communities in the project area would improve watershed health by creating and sustaining aquatic and wildlife habitat, storing groundwater and recharging aquifers, and maintaining water quality. Compensatory mitigation would improve wetland functions using a variety of persistent native vegetation types to replace wetlands, which are also likely to enhance general wildlife habitat, and ERO Project#22-078 5 ERO Resources Corporation Wattenberg Lakes Gravel Mining Revised Compensatory Mitigation Plan Weld County, Colorado provide nutrient processing to the stream system. Wetland functions would be enhanced by creating a more diverse wetland system, improving water quality by reducing the nutrients entering the South Platte River, providing more connectivity and reducing barriers between wetland areas, increasing water distribution through the wetlands by creating large wetland complexes, and enhancing adjacent areas with native upland vegetation. Wetland Mitigation Proposed compensatory mitigation for permanent wetland impacts would be permittee-responsible, on - site, in -kind, and at a 1:1 ratio. The 32.57 acres of wetland mitigation required would be created primarily in the Phase III mining area (Figure 4). Wetlands would be supported by groundwater, which was the primary hydrology source for the wetlands impacted by the project. The wetland areas would be a combination of palustrine emergent, scrub -shrub, and saltgrass wet meadow wetlands as described above. The created wetlands would be seeded with a wetland seed mix and planted with a mix of wetland plugs and willow stakes. Per the IP authorization, the mitigation areas will be seeded with the following native species (Table 1). A detailed planting plan that provides information about the herbaceous seed and plug plantings, and the quantities of proposed tree and shrub plantings is being developed and will be provided at a later date. To establish baseline conditions, Holcim had groundwater data collected monthly from groundwater monitoring wells starting in January 2002. Furthermore, in accordance with Special Condition G and Special Condition S of the IP authorization, Holcim has been conducting groundwater monitoring for the project since 2006, to document detailed site conditions and groundwater levels in the area. Based on the mitigation plan authorized in the IP, elevations for the wetland mitigation areas will be determined from baseline groundwater data; however, due to the proposed reservoir modifications, which include expanding Pond 1 and creating a larger slurry wall in the southwest section of the project area, additional groundwater analysis will be necessary to understand final groundwater elevations in the mitigation areas. Mounding is anticipated to occur from the slurry wall along Pond 3, which could result in higher groundwater levels in the mitigation areas. However, shadowing may occur from the construction of the slurry wall around Pond 1, which may reduce groundwater levels in the mitigation area. Due to these potential effects to groundwater, Holcim is proposing to continue monitoring groundwater elevations in these areas until 1- to 2 -years post -construction of the slurry wall around Pond 1. Once groundwater elevations have stabilized, wetland mitigation would be constructed to the appropriate elevations to meet hydrology requirements. Although this may result in a temporal delay in wetland mitigation, the South Platte Valley wetlands created on the east side of the South Platte River will remain as temporal wetland mitigation until the final wetland mitigation areas are established.

Holcim plans to dewater and mine an additional 6.2 acres within the future Pond 1 (Struck Pond) area, followed by the conversion of the mined area and into a lined water storage facility. The water storage will be surrounded by a slurry wall with a perimeter drain to minimize hydrologic impacts to the nearby area. The exhibit documents the depth and direction of groundwater flow, the nature of the subsurface geologic materials through which it flows (Figure G-2), potential interactions with streams, lakes, canals, or other surface water bodies in the area, and the potential impacts to surrounding water users due to dewatering, mining, and slurry wall installation. 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 surface 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 South Platte River. The South Platte River was utilized in the past for the discharge of dewatering water during mining. Current dewatering water is being sent to the Stillwater Ski Lake (Figure G-1). Short-term dewatering will be required for the additional mined acreage prior to the construction of the slurry wall. The site has been dewatered for mining in the past, where drawdown was observed to be very localized in nature (see hydrographs in Appendix G) because of the presence of the river which mitigates excessive groundwater drawdown that might affect groundwater users in the area. Also, the presence of the river has the collateral benefit of mitigating the potential shadow effect potentially caused by the slurry wall that will surround the Struck Pond. (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 may be affected by the proposed mining operations. TETRA TECH Page 118 Wattenberg Mine, Exhibit G —Water Information May 2023 Please see Exhibit C Pre -Mining Maps for the location of all tributary watercourses, 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 The Wattenberg Lakes site is underlain by multiple aquifers: • The alluvial deposits Post -Piney Creek Alluvium and Piney Creek Alluvium of the South Platte River. o described in: Colton, Roger B., 1976. "Geologic Map of the Boulder -Fort Collins -Greeley area, Colorado", USGS Miscellaneous Geologic Investigations Map I -855-G. (See Figure G- 2) • The Lower Arapaho Aquifer 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 • The Laramie -Fox Hills Aquifer 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 conceptual model of the subsurface geology and groundwater flow was developed from the geologic map for the area and the subsurface conditions observed during the installation of the monitoring well network at the Wattenberg Lakes site (Figure G-3). Based on water levels measured in these wells, groundwater elevation maps were developed for both low-water conditions associated with the winter non -irrigation season and conditions that exist at the end of the irrigation season in August (Figures G-4 and G-5, respectively). Figures G-4 and G-5 indicate a northeasterly flow direction that becomes flatter and more northerly as the water crosses the site. Figure G-4 groundwater contours show the impacts of the recent and current Struck Pond dewatering, where this water is sent to the Stillwater Ski Lake. There will be minimal additional mining activities, limited to within the Struck Pond area; changes to current land surfaces will be primarily due to reclamation activities as outlined in Exhibit E. Pond 3 currently has a slurry wall, constructed in 2013, which influences groundwater flow in the immediate vicinity. The planned Struck Pond expansion will involve dewatering prior to and during mining. Shallow groundwater flow will be impacted during dewatering activities associated with the expansion although these impacts are expected to be limited to the aquifer only around this area. Due to the permeability contrast between the gravel aquifer and the bedrock beneath it, hydraulic changes due to mining will not impact the underlying Laramie -Fox Hills 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 nearby South Platte River, and the minimal additional mining operations. The reclamation plan for the mine includes the placement of a slurry wall and perimeter drain around the Struck Pond. The Struck Pond will then be used as water storage for the City of Westminster. Changes to the hydrologic balance in the area will be limited to minor, localized alterations of the existing groundwater flow patterns due to the slurry wall. 2.0 HISTORIC USE The Wattenberg Lakes property has been used for mining since the Colorado Division of Reclamation, Mining and Safety (DRMS) issued the original permit in 2004. The reclaimed Parker-Dersham aggregate mine and pond, with slurry wall around it, lies to the south of the property, as does the Stillwater Ski Lake, which is man-made and unlined. Agricultural lands exist to the west of the site. Additional aggregate mines and industrial operations occur across the South Platte River to the east. OTETRA TECH Page 208 Wattenberg Mine, Exhibit G —Water Information May 2023 3.0 HYDROGEOLOGIC SETTING Geology The geology mapped at land surface beneath the site consists of alluvial deposits comprised of sand, silt, and gravel primarily (Figure G-2) of the Piney Creek and Post -Piney Creek Alluvium units. On site wells (Figure G-3) were installed in 2002, however no boring logs were found. The depth of the wells on site indicates up to 25 feet of alluvial material overlaying bedrock. Most wells appear to be highly transmissive. Water levels measured in the wells are generally less than 10 ft deep and approach the ground surface in some cases (see hydrographs in Appendix G). The shallow bedrock of the Laramie -Fox Hills aquifer consists of weathered, consolidated sedimentary rock varying from claystone to siltstone. 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. Groundwater Groundwater at the site represents a combination of water that flows through the high -permeability alluvial deposits parallel to the South Platte River and water that infiltrates due to the agricultural fields that dominate the land use to the west of the river. As groundwater approaches 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. The direction of regional shallow groundwater flow is therefore toward the northeast but changing to a near northerly direction near the river. This is especially apparent during the winter when compared to the end of the agricultural season in late August (Figures G-4 and G-5, respectively) and may be due to the influence of agricultural runoff coming from west of the site. Monitoring well MW -6 has limited groundwater elevation data as this well was inaccessible and not monitored prior to 2020. The small amount of available data shows limited water in this well compared to the saturated thickness of the other site wells (Appendix G). This well was refurbished in August 2021 which resulted in an additional 3 feet of water in the well. Assuming the well was installed correctly and is not damaged, it is possible this discrepancy is due to the upgradient slurry wall around the Parker-Dersham Pond, which may be casting a groundwater shadow on this well. In addition, while dewatering has taken place previously, the most recent dewatering of the unlined Struck Pond began in late 2022. The resulting water is routed to the unlined Stillwater Ski Lake, where the effect of additional water into this lake is noticeable as shown in Appendix G and Figure G-4. Existing Monitoring Wells A network of monitoring wells was installed in 2002 to characterize the groundwater conditions at the Wattenberg Lakes property (Figure G-3). The boreholes for the wells were drilled to the bedrock contact and typically have a high saturated thickness. These wells generally show the direction of groundwater flow to be in a northeasterly to northerly direction, generally in equilibrium with the river water surface elevations, although as discussed above MW -6 may be exhibiting signs of a localized groundwater shadow caused by the upgradient Parker-Dersham Pond slurry wall. Well Inventory In April 2023, a well inventory of the Affected Area and adjacent areas was conducted to identify wells near the site. The inventory included a search of the State of Colorado Office of the State Engineer database of wells located within 1 mile of the Affected Area (Table 1). The well inventory identified 442 wells within 1 mile of the Affected Area. Figure G-6 shows the Affected Area and the constructed well locations on file with the Colorado Division of Water Resources, where the numbers shown on Figure G-6 correspond to the first column numbers shown in Table 1. The majority of these wells are screened in the shallow alluvial material, although a handful are noted to be screened in the Laramie -Fox Hills aquifer and the Lower Arapaho aquifer. Wells in this area are noted to be used for irrigation, domestic use, stock water, monitoring, industrial, and municipal use. TETRA TECH Page 3j8 Wattenberg Mine, Exhibit G —Water Information May 2023 4.0 HISTORIC AND FUTURE GROUNDWATER LEVELS Appendix G presents hydrographs for the nine on -site monitoring wells. Labeled, dashed lines are included to indicate mine dewatering in 2006 and the completion of the Pond 3 slurry wall in 2013. Wells MW -2 and MW -3 experienced noticeable groundwater elevations declines during dewatering which both recovered quickly due to the high transmissivity of the area. Many of the monitoring wells show a rise in groundwater elevations following 2013. Upgradient wells such as MW -7 and MW -8 exhibit gradually climbing water levels, while MW -2 and MW -5 show quick water level increases at the end of 2013 followed by plateauing values. Figure G-3 shows that MW -2 and MW -5 are immediately upgradient of the Pond 3 slurry wall. In the absence of other information, the water level increases at MW -2 and MW -5 could be interpreted as groundwater mounding due to the slurry wall. However, due to the major flooding of the area in September 2013 and the gradual water elevation increase at upgradient wells MW -7 and MW -8, the late 2013 water level increase at MW -2 and MW -5 does not conclusively point to a notable groundwater mound. These wells show relatively consistent groundwater elevations since the installation of the slurry wall, although with the general water level increases across the rest of the site this could indicate some form of minor groundwater shadow. Due to the high transmissivity of the area, and based on the hydrographs is Appendix G, it is anticipated that implementing the remaining mining activities and associated dewatering, the Struck Pond slurry wall installation, and the reclamation work will have minimal impact on local groundwater elevations. Nevertheless, it is important to recognize that the Struck Pond may create a partial barrier to groundwater flow due to its positioning between locations that currently have slurry walls, namely Pond 3 and the Parker-Dersham Pond. Due to the unique positioning, the hydraulic impacts from the Struck Pond both during dewatering and potentially after the slurry wall is installed may be greater than without the two other structures in place. The perimeter drain around the slurry wall is expected to minimize these potential effects. Structures and wells (not including monitoring wells, Figure G-6 and Table 1) located within % mile downgradient of the Struck Pond include: • Stillwater Ski Lake • Huett Seep/Ditch • Well 10 — permit number 21385 - Well 80 — permit number 191-WCB • Well 231 permit number 6291-R • Well 272 — permit number 49717-F Wells 10 and 272 are not screened in the shallow alluvial aquifer and would therefore be unaffected by dewatering or the slurry wall. Wells (not including monitoring wells) located within 'A mile upgradient and cross gradient from the Struck Pond which could be affected by dewatering include: • Well 36 — permit number 138214--A • Well 138 — permit number 132424--A • Well 166 — permit number 130499--A • Well 171 — permit number 138214- • Well 173 — permit number 19893- • Well 223 — permit number 202399- • Well 295 — permit number 48617-F • Well 387 — permit number 6647-F • Well 392 — permit number 213-WCB • Well 438 — permit number 158810--A Wells 166, 295, and 438 are not screened in the shallow aquifer and would therefore be unaffected by dewatering or the slurry wall. TETRA TECH Page 4j8 Wattenberg Mine, Exhibit G — Water Information May 2023 5.0 AVAILABLE SATURATED THICKNESS The available well information for the monitoring wells on site indicates bedrock was encountered at depths of up to 27 feet below ground surface. Water levels at the time of well installation in 2002 ranged from 2 to 9 feet below ground surface. Based on this data, the saturated thickness of aquifer beneath the site ranges from approximately 7.5 to 22.5 ft (Table 2). 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 likely to be required to provide the allowed pumping rates of 15 gpm. Mine dewatering in 2006 was not observed to have an adverse effect on off -site wells, and minimal, short-term dewatering activities are anticipated to occurring during the remaining mining, where dewatering water will be routed to the nearby Stillwater Ski Lake. Owing to this, the response to previous dewatering activities noted in Appendix G, and the high transmissivity of the shallow alluvium, adverse effects to off -site wells are not anticipated. 6.0 HYDRAULIC IMPACTS There will be 6.2 acres of additional mining at the Wattenberg Lakes site, limited only to the Struck Pond expansion area, which will require temporary, short-term dewatering. During dewatering a cone of depression will form around the Struck Pond excavation and spread to some extent over time. Currently, dewatering water is sent to Stillwater Ski Lake; this helps to offset downgradient impacts. Nevertheless, the dewatering has the potential to impact the wells listed above in addition to the ski lake and the Huett Seep/Ditch. Due to the proximity to the South Platte River, the spread of dewatering impacts is expected to be limited as was observed during the period of time shown in the hydrographs for the wells around Pond 3. The short-term nature of the dewatering will keep any long-term impacts to a minimum. Based on the high water table and the responses shown in the Appendix G hydrographs, additional dewatering is unlikely to have a long-term effect on nearby water wells. The slurry wall construction around the Struck Pond may have a localized effect on groundwater, the Huett Seep/Ditch, and the Stillwater Ski Lake, namely some mounding and shadowing. Based on the observed hydraulic response to construction of the slurry wall around Pond 3, these responses will likely be minimal and localized in nature and will likely not affect any nearby water wells. The hydrologic effects may be amplified locally but only slightly due to the location of the Struck Pond between two structures that currently have slurry walls, but it is anticipated that the perimeter drain on the Struck Pond will help to minimize these potential effects. 7.0 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. (5) The Operator/Applicant shall affirmatively state that the Operator/Applicant has acquired (or has applied for) a National Pollutant Discharge Elimination System (NPDES) permit from the Water Quality Control Division at the Colorado Department of Health and Environment, if necessary. There will be minimal water use after mining when most of the site is in the reclamation phase. The minor amount of mining at the site will intercept some groundwater tributary to the South Platte 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 that is ponded or removed through dewatering for storage in the Stillwater Ski Lake. Evaporative losses were calculated as the difference between OTETRA TECH Page 5i8 Wattenberg Mine, Exhibit G — Water Information May 2023 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 45 inches. Precipitation was obtained for the nearby City of Brighton and the total annual precipitation for this site was determined to be 15.6 inches. Effective precipitation was calculated as 70 percent of total precipitation; thus, the average annual effective precipitation was determined to be 10.9 inches. The resulting evaporative loss rate is therefore 29.4 inches. The maximum total annual evaporative consumptive use during the short period of additional mining at the site is estimated at 7 acre-feet, which is primarily a function of the water used for dust control and the water retained within removed materials. 8.0 MONITORING AND MITIGATION PLAN This Groundwater Monitoring and Mitigation Plan is prepared as part of Holcim's application to the DRMS for a revised permit for the Wattenberg Lakes 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 due to activities at the site, this plan addresses how any adverse effects to groundwater would be mitigated, should they occur. If needed, Holcim will submit a Temporary Substitute Water Supply Plan to the State Engineer's Office for approval. The Temporary Substitute Water Supply Plan is designed to protect senior vested water rights and mitigate potential depletions of flows in adjacent waterways. Mining Plan The 6.2 acres of additional mining will occur on the north and west edges of the currently ponded area of Struck Pond. Some dewatering will be required to complete this phase but will be temporary and short term in nature. Dewatering is planned for a period of approximately 10 months to accommodate earthwork activities, within which mining is planned over a period of 2 months. The mined aggregate will be placed on the conveyor (north side of Struck Pond) and conveyed to Holcim's Platte Valley Plant, and temporary stockpiles will be placed to the west and north of the current Struck Pond. Following mining activities, the Struck Pond will be expanded as shown in Figure G-1 and will be surrounded by a slurry wall and perimeter drain. Monitoring The monitoring plan will consist of regular data collection from the set of monitoring wells currently in place around the perimeter of the Wattenberg Lakes permit area (Figure G-3). Data collection activities will include monthly measurement of water levels in wells. Water Quality Parameters As mentioned above, due to the absence of large quantities of potential pollutants on site and the absence of water quality samples collected at this site in the past, additional water quality samples are not proposed. Domestic and Irrigation Water Wells Active domestic and irrigation wells are shown In Figure G-6 and Table 1. In the event of a well owner complaint, either due to water quality or quantity, Holcim commits to reporting any complaints received from well owners to the DRMS within 48 hours, investigating the complaint as soon as practical, and submitting the results to the DRMS for evaluation within 30 days. Dewatering Discharge Based on data collected from monitoring wells, the depth to groundwater is shallow and will likely be around 2 feet below ground surface in the area of the Struck Pond. 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. OTETRA TECH Page 618 Wattenberg Mine, Exhibit G — Water Information May 2023 Holcim's Wattenberg Lakes facility complies with applicable requirements in the Colorado Discharge Permit System (CDPS) General Permit COG500000 for Sand &, Gravel Mining Wastewater & Storm Water combined. The Colorado Department of Health and Environment (CDPHE) Water Quality Control Division (WQCD) considers stormwater runoff combined with mine dewatering water to be process water. The available monitoring well data will be used to observe changes in alluvial groundwater flow associated with mining and reclamation activities. Baseline data collected from the monitoring program will provide a range of water levels for comparison with groundwater levels during site activities under this permit amendment. 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 cases where water extraction is not being conducted. In the event of a well owner complaint, Holcim commits to reporting any complaints received from well owners to the DRMS within 48 hours, investigating the complaint as soon as practical, and submitting the results to the DRMS for evaluation within 30 days. For the investigation, the first level of response will be to review water level data from the monitoring well network and, if available, a measurement of the water level in the well of those making the complaint. Information will be evaluated to determine if the complaint may be tied to dewatering or the slurry walls. If the data indicates that there is no reason to believe the well of those making the complaint was impacted by dewatering or the slurry walls, that will conclude the action taken by Holcim. If the data does not clearly show there is no impact, as a second level of response Holcim will present a contract to the well owner requesting access to the well to perform mechanical and electrical inspection and testing of the well and associated system, e.g., the pressure tank. The agreement will explain that if the problem with the well is not due to a lower water level and is instead due to a mechanical or electrical issue, the well owner will be responsible for the repairs. If the well is determined to be in good working order and the problem is due to a lower water level, then 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 Holcim's activities or is not solely a result of Holcim's activities, Holcim will reduce or cease mitigation accordingly. In the event of a complaint that a well has become unusable, and based on the inspection results described above, Holcim 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 activities. The DRMS, and potentially the Mine Land Reclamation Board (MLRB), are responsible for determining if mitigation is required, as well as when and how any mitigation measures are implemented and discontinued after the initial complaint is received. Should DRMS or MLRB conclude that mitigation action is required, Holcim will begin to implement one or more mitigation measures. 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 Holcim. 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. OTETRA TECH Page 718 Wattenberg Mine, Exhibit G — Water Information May 2023 • Modifying a well to operate under lower groundwater conditions. This could include deepening existing wells or lowering the pumps. All work would be completed at Holcim'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, Holcim will notify the DRMS of the condition, action taken, and will report the results and present a plan for monitoring the mitigation.

Based on the IPaC resource list, there are no critical habitats at this location although the threatened and endangered species included in the list may be potentially affected by activities at this site. There are no known threatened/endangered species within the proposed project boundary. Prior to mining under the 2004 DRMS Permit, the Wattenberg Lakes site was a working ranch used primarily for livestock grazing with some areas cultivated for tree production and other crops. The site contained a mixture of open water, riparian, wetland, and upland habitats consisting of native vegetation. Cattail marsh, wet meadow, and stands of willow and mature cottonwoods were all found on the site. As a result of mining, with reclamation not completed, there are fewer areas of native vegetation and more areas of disturbed lands. However, reclamation will involve establishing a mixture of open water, riparian, wetland, and upland habitats consisting of native vegetation. Wildlife known to be common or abundant in Weld County, and which might occur within or near the proposed project site include a variety of amphibians, reptiles, birds, and mammals. Frogs, toads, salamanders, lizards, and snakes would all be expected to inhabit areas similar to those found within or near the proposed site, with more abundance in areas not disturbed by mining and in previously disturbed areas as they are reclaimed. Common species could include the bullfrog, plains spadefoot toad, tiger salamander, plains garter snake, and fence lizard. Many birds may use habitats similar to those found at the proposed Wattenberg Lakes site, either year-round, seasonally for nesting, or temporary for roosting during migration. Some of the common or abundant species could include robins, starlings, grackles, magpies, blackbirds, cowbirds, orioles, finches. sparrows, swallows, wrens, yellowthroats, larks, kingbirds, and doves. In 2004, prior to mining burrowing owls were observed on portions of the site during the summer months. Because of the abundant wetland and open water habitat within and near the proposed project site, shore birds and waterfowl such as killdeer, herons, gulls, pelicans, ducks, Canadian geese, and grebes might also be present. It could be expected that most mammals common or abundant in Weld County would be found near or within the Wattenberg Lakes site. Smaller mammals that might be found at the site might include bats, mice, voles, gophers, cottontail rabbits, squirrels, muskrats, raccoons, and skunks. Although several species of mice may occur within the site, critical habitat for the endangered Preble's Meadow Jumping Mouse is not present (USFSW, 2023). Some of the larger mammals could include both mule and white-tailed deer, coyote, and fox. Mining and reclamation operations may disturb some of the wildlife within the permit boundary and adjacent area. However, mining activities will be confined to specific areas, with reclamation shortly after mining. Other earthwork prior to reclamation be of short duration to limit the total disturbed acreage at any one time. This will help limit the disturbance to wildlife in the area. 2.0 REFERENCES USFWS (U.S. Fish and Wildlife Service). 2023.

The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly affected by activities in the project area. However, determining the likelihood and extent of effects a project may have on trust resources typically requires gathering additional site -specific (e.g., vegetation/species, surveys) and project -specific (e.g., magnitude and timing of proposed activities) infrmati�in.

The primary information used to generate this list is the known or expected range of each species. Additional areas of influence (AO') for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly affected by activities in that area (e.g., placing a dam upstream of a fish population even if that fish does not occur at the dam site, may indirectly impact the species by reducing or eliminating water flow downstream). Because species can move, and site conditions can change, the species o list are not guaranteed to be found on or near the project area. To fully determine ny ' potential effects to species, additional site -specific and project -specific informationIs often required.

Probability of Presence (I) Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4 - week months.) A taller bar indicates a higher probability of species presence. The survey effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high. Breeds Oct 15 to Jul 31 Breeds Mar 15 to Aug 2 Breeds lylar 15 to Aug 15 Breeds elsewhere How is the probability of presence score calculated? The calculation is done in three steps: hops://ipac.ecosphere.fws.gov/location/LNE5CWJ4CVF7TO2167UH5XMZZ4/resources 7/12 4/20/23, 1:46 PM IPaC: Explore Location resources 1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25. 2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2. 3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the *- probability of presence score. To see a bar's probability of presence score, simply hover your mouse cursor over the bar. Breeding Season ( ) ar S Yellow bars denote a very liberal estimate of the time -frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area. Survey Effort (I) Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys. Al%) To see a bar's survey effort range, simply hover your mouse cursor over the bar. No Data ( ) es< IC A week is marked as having no data if there were no survey events for that week. Survey Timeframe Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas off the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse. probability of presence breeding season I survey effort no data SPECIES JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC Bald Eagle Non -BCC Vulnerable Chimney Swift BCC Rangewide (CON) I died, ilia a' is 'ill uS evoi pee iii a I 1111 --- ._�— -4- + https://ipac.ecosphere.fws.gov/location/LNE5CWJ4CVF7TO2I67UH5XMZZ4/resources 8/12 4/20/23. 1:46 PM IPaC: Explore Location resources Ferruginous Hawk BCC - BCR Lesser Yellowlegs BCC Rangewide (CON) I+ I I # 4 r lug ban ltst Snail tttis a anima: et. 1+1 I I I I Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds. Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site's %Pr b01 What does IPaC use to generate the list of migratory birds that potentially occur in my specified location? 40% igiL \\ire w The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location. S W The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identified as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to offshore activities or development. Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the Rapid Avian Information Locator (RAIL) Tool. What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specified location? The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN).. This data is derived from a growing collection of survey, banding, and citizen science datasets. Probability of presence data is continuously being updated as new and better information becomes available.

How do I know if a bird is breeding, wintering or migrating in my area? https://ipac.ecosphere.fws.gov/location/LNE5DA/J4CVF7TO2167UH5XMZZ4/resources 9/12 4/20/23, 1:46 PM IPaC: Explore Location resources To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may query your location using the RAIL Tool and look at the range maps provided for birds in your area at the bottom of the profiles provided for each bird in your results. If a bird an your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area. What are the levels of concern for migratory birds? Migratory birds delivered through IPaC fall into the following distinct categories of concern: 1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands); 2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and 3. "Non -BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non -eagles) potential susceptibilities in `� offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing). Although it is important to try to avoid and minimize impacts to all birds, efforts`should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures yoU can implement to help avoid and minimize migratory bird impacts and requirements for eagles,-p1ease see the FAQs for these topics.

For additional information on marine bird tracking data, see the Diving Bird Study_ and the nanotag studies or contact Caleb Spiegel or Pam Loring. What if I have eagles on my list? If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur. Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my specified location". Please be aware this report provides the "probability https://ipac.ecosphere.fws.gov/location/LNE5CWJ4CVF7TO2167UH5XMZZ4/resources 10/12 4/20/23, 1:46 PM IPaC: Explore Location resources of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey effort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources page.

Wetlands in the National Wetlands Inventory (NWI) Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes. For more information please contact the Regulatory Program of the local U.S. Army Corps of Engineers District. https://ipac.ecosphere.fws.gov/location/LNE5CWJ4CVF7TO2I67U H5XMZZ4/resources 11/12 4/20/23, 1:46 PM IPaC: Explore Location resources Wetland information is not available at this time This can happen when the National Wetlands Inventory (NWI) map service is unavailable, or for very large projects that intersect many wetland areas. Try again, or visit the NWI map to view wetlands at this location. Data limitations The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information on the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A margin of error is inherent in the use of imagery; thus, detailed on -the -ground inspection of any particular site may result in revision of the wetland boundaries or classification established through image analysis,, The accuracy of image interpretation depends on the quality of the imagery, the experience of the Erri"'*' analysts, the amount and quality of the collateral data and the amount of ground truth verification wprk conducted. Metadata should be consulted to determine the date of the source imagery used`and anij mapping problems. Wetlands or other mapped features may have changed since the date of the imagery or field work. There may be occasional differences in polygon boundaries or classifications between the information depicted on the map and the actual conditions on site. Data exclusions Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation thtaare found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Someldeapwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. 1' Data precautions Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate Federal, state, or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such activities. https://ipac.ecosphere.fws.gov/location/LNE5CWJ4CVF7TO2I67UH5XMZZ4/resources 12/12 Wattenberg Lakes Amendment, Exhibit I — Soil Information May 2023 EXHIBIT I - SOIL INFORMATION According to the Web Soil Survey online database map pulled on April 6, 2023 for the DRMS permit amendment area located in Unincorporated Weld County, Colorado fWeb Soil Survey (usda.gov)1, there are three major soil types within the project site: 1. Altvan loam 2. Aquolls and Aquents 3. Dacono clay The location of these soil types is illustrated on the attached map and Custom Soils Report. Altvan Loam: The Altvan loam soil type is present within the proposed project site at 0 to 1 percent slopes and 1 to 3 percent slopes. They are deep, level and nearly level, well -drained terrace soils formed in alluvium. Permeability and available water capacity are moderate. For the lower sloping areas, surface runoff is slow, and the erosion hazard is low. In areas with steeper slopes, surface runoff is medium, but the erosion hazard is still low. This soil is used almost entirely for irrigated crops. It is suited to all crops commonly grown in the area, but the high clay content and rapidly permeable substratum slightly restrict some crops. The potential is only fair to good for urban and recreational development. The main limitations are the shrink swell, potential of the subsoil as it wets and dries and the rapid permeability of the sand and gravel substratum. The soil can produce habitat elements that are highly suitable for open -land wildlife including pheasant, cottontail, and mourning dove. Plantings of trees and shrubs commonly grown in the area are generally well suited to the soil. Aquolls and Aquents, gravelly substratum: The Aquolls and Aquents are deep, level and nearly level, poorly drained soils formed in alluvium. Located on flood plains along major streams throughout the area, the soil type is found in areas that are subject to flooding. It is also the roost dominant soil type within the proposed project site. The Water table is at or near the surface early in spring and recedes to as deep as 48 inches late in fall. Areas containing these soils are used mainly for rangeland and wildlife habitat. The potential is good for development of wetland wildlife habitat and also as a source of sand and gravel. Wetness and the hazard of flooding are the main limitations in farming and for most other purposes. Dacono Clay The Dacono clay soil type is present within the proposed project site at 0 to 1 percent slopes and 1 to 3 percent slopes. They are deep, level and nearly level, well -drained terrace soils formed in alluvium. Permeability is moderately slow and available water capacity moderate. For the lower sloping areas. Surface runoff is slow, and the erosion hazard is low. In areas with steeper slopes surface runoff is medium, but the erosion hazard is still low. The soil type is used almost entirely for irrigated crops. It is suited to all crops commonly grown in the area, but the high clay content and rapidly permeable substratum slightly restrict some crops. The soil is only fair to good for urban and recreational development. The moderate to high shrink -swell potential, low strength, and moderately slow permeability create problems in dwelling and road construction. The soil can produce habitat elements that are highly suitable for open -land wildlife including pheasant, cottontail, and mourning dove. Plantings of trees and shrubs commonly grown in the area are generally well suited to this soil. OTETRA TECH Page 1I1 USDA United States Department of — Agriculture N RCS Natural Resources Conservation Service A product of the National Cooperative Soil Survey, a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local participants Custom Soil Resource Report for Weld County, Colorado, Southern Part DRMS Amendment Area Parcel S April 20, 2023 Preface Soil surveys contain information that affects land use planning in survey areas. They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nres.usda.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nres142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil -vegetation -landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil 5 Custom Soil Resource Report scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil -landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil -landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field -observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and 6 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas 11 Custom Soil Resource Report are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into Iandforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha -Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 12 Custom Soil Resource Report Weld County, Colorado, Southern Part 1—Altvan loam, 0 to 1 percent slopes Map Unit Setting National map unit symbol: 361j Elevation: 4,500 to 4,900 feet Mean annual precipitation: 14 to 16 inches Mean annual air temperature: 46 to 48 degrees F Frost -free period: 130 to 150 days Farmland classification: Not prime farmland Map Unit Composition Altvan and similar soils: 90 percent Minor components: 10 percent Estimates are based on observations, descriptions, and transects of the mapunit.

The site contained a mixture of open water, riparian, wetland, and upland habitats consisting of native vegetation. Cattail marsh, wet meadow, and stands of willow and mature cottonwoods were all found on the site. Native grasses including wheat grasses, switchgrass (Panicum virgatum), blue grama (Bouteloua gracilis), and buffalograss (Bouteloua dactyloides) tended to dominate soils found in upland areas. Trees best suited for these upland soils include Rocky Mountain juniper (Juniperus scopulorum), eastern redcedar (Juniperus virginiana), ponderosa pine (Pinus ponderosa), Siberian elm (Ulmus pumila), Russian olive (Elaeagnus angustifolia), and hackberry (Celtis). The shrubs best suited are skunkbush (Rhus trilobata), sumac (Rhus), lilac (Syringa), Siberian peashrub (Caragana arborescens), and American plum (Prunus americana). Current vegetation information, obtained from a wetland survey for the site completed by ERO in June and August 2022, is presented in the Wetland Delineation Report produced from that survey (attached to this exhibit). The project area primarily consists of disturbed uplands dominated by kochia (Bassia scoparia), Canada thistle (Cirsium arvense), smooth brome (Bromus inermis), and foxtail barley (Hordeum jubatum), with patches of sandbar willow (Salix exigua) and plains cottonwood (Populus deltoides). Gravel pits of various sizes occur in the project area, with some containing open water and others that are dry. Wetlands are present throughout the project area, with the majority having established in the gravel mining cells. The Huett Ditch generally traverses the project area from south to north through the east side of the project area, before turning west at the north boundary; this seep/ditch consists primarily of narrowleaf cattail (Typha angustifolia) wetlands. Fringe wetlands are also located along the banks of the South Platte River. Most wetlands in the project area are dominated by pale smartweed (Persicaria lapathifolia), narrowleaf cattail, broadleaf cattail (Typha latifolia), and cosmopolitan bulrush (Schoenoplectus maritimus). Reclamation will involve establishing a mixture of open water, riparian, wetland, and upland habitats consisting of native vegetation.

ERO assessed the project area for potential isolated wetlands, jurisdictional wetlands, and other waters of the U.S. (WOTUS). The Clean Water Act protects the chemical, physical, and biological quality of WOTUS. The U.S. Army Corps of Engineers' (Corps) Regulatory Program administers and enforces Section 404 of the Clean Water Act. Under Section 404, a Corps permit is required for the discharge of dredged or fill material into wetlands and other WOTUS (streams, ponds, and other water bodies). On June 22, 2020, the Environmental Protection Agency (EPA) and Corps' Navigable Waters Protection Rule (NWPR) to define "waters of the United States" became effective in 49 states and in all U.S. territories (EPA 2020). A preliminary injunction was granted for Colorado. On March 2, 2021, the United States Court of Appeals for the 10th Circuit vacated the stay on the NWPR in Colorado, thereby ruling the NWPR effective in Colorado. After April 23, 2021, the jurisdiction of wetlands and other potential WOTUS in Colorado was to be determined using the NWPR. However, on August 30, 2021, the Arizona District Court remanded and vacated the NWPR. In response, the EPA and Corps have halted implementation of the NWPR and, until further notice, are interpreting WOTUS consistent with the pre -2015 regulatory regime (also referred to as the "Rapanos" guidelines). On January 18, 2023, the EPA and Corps published a final rule to define WOTUS (new rule). The new rule will codify the pre -2015 approach to WOTUS, with some changes to the definition of "adjacency" and "significantly affect" that could expand jurisdiction of certain streams or wetlands. The new rule went into effect on March 20, 2023; however, there is a strong potential it will be challenged in court, affecting its implementation. As such, the identification of WOTUS in this report follows the current Rapanos guidelines. Potential rulings and guidance in the future could change the results of this report regarding the jurisdictional status of waters and wetlands in the project area. While ERO may provide its opinion on the likely jurisdictional status of wetlands and waters, the Corps will make the final determination of jurisdiction based on the current rulings. Under the Rapanos guidelines, the Corps considers traditionally navigable waters (TNWs), wetlands adjacent to TNWs, and tributaries to TNWs that are relatively permanent waters (RPWs) and their abutting wetlands jurisdictional waters. Other wetlands and waters that are not TNWs or RPWs will require a significant nexus evaluation to determine their jurisdiction. A significant nexus evaluation ERO Project #22-193 1 ERO Resources Corporation Wetland Delineation Report Wattenberg Lakes and South Platte Valley Weld County, Colorado assesses the flow characteristics and functions of a tributary and its adjacent wetlands to determine if they significantly affect the chemical, physical, or biological integrity of downstream TNWs. Location The project area is in Sections 25 and 36, Township 1 North, Range 67 West; and Sections 30 and 31, Township 1 North, Range 66 West of the 6th Principal Meridian in Wattenberg, Weld County, Colorado (Figure 1). The UTM coordinates of the approximate center of the project area are 514393mE, 4429885mN of NAD 83 Zone 13N. The longitude/latitude of the project area is 104.831342°W/40.019051°N. The elevation of the project area is approximately 4,940 feet above sea level. Summary of Ecological Setting The U.S. Department of Agriculture (USDA) maps the project area within the southern part of the Central High Plains Major Land Resource Area, which is characterized by a flat to gently rolling landscape formed by glacial drift material and sediment deposition from the Rocky Mountains (USDA and Natural Resources Conservation Service (NRCS) 2006).. This Major Land Resource Area is part of the Colorado Piedmont section of the Great Plains physiographic province and ranges in elevation from 3,000 to 7,800 feet. The climate of the area is typical of mid -continental semiarid temperate zones, but the strong rain shadow effect of the Southern Rocky Mountains makes the area somewhat drier. The average annual precipitation is between 12 and 18 inches, most of which occurs between April and September. The mean annual temperature is between 45°F and 55°F, and the number of frost -free days ranges from 135 to 190. The project area is further divided into the Flat to Rolling Plains ecoregion of Colorado (Chapman et al. 2006). The geology of the Flat to Rolling Plains ecoregion consists largely of silty soils with eolian deposits. Located in the South Platte River watershed of central Colorado, streams flow from west to east out of the Front Range mountains and foothills or from southeast to northwest off the Palmer Divide and into the South Platte River. The South Platte River converges with the North Platte River just west of Ogallala, Nebraska, to form the Platte River. The Platte River is tributary to the Missouri River, which eventually flows into the Mississippi River. Most of the tributaries that flow into the South Platte River watershed contain riparian corridors dominated by deciduous woodlands and transitional shrubs and grasslands. The majority of the ecoregion historically consisted of shortgrass and midgrass prairie. Most of the land use has gone or is currently undergoing a shift from dryland farming to urban development. The development has resulted in a shift from native habitat to urban areas that contain a high number of manmade lakes and gravel pits, public infrastructure, buildings, and narrower riparian corridors along streams and rivers in the region.

Wetland Delineation Report Wattenberg Lakes and South Platte Valley Weld County, Colorado Project Area Description The project area is located west of US Hwy 85 between County Road (CR) 6 and East 168th Avenue on either side of the South Platte River in Wattenberg, Colorado (Figure 1). The project area lies within an existing gravel mine site and is surrounded by a mixture of agricultural fields, industrial sites, and residential development. The project area primarily consists of disturbed uplands dominated by kochia (Bassia scoparia), Canada thistle (Cirsium arvense), smooth brome (Bromus inermis), and foxtail barley (Hordeum jubatum), with patches of sandbar willow (Salix exigua) and plains cottonwood (Populus deltoides). Gravel pits of various sizes occur in the project area, with some containing open water and others that are dry. Wetlands are present throughout the project area, with the majority having established in the gravel mining cells. The Huett Ditch generally traverses the project area from south to north through the project area, before turning west at the north boundary, and consists primarily of narrowleaf cattail (Typha angustifolia) wetlands. Fringe wetlands are also located along the banks of the South Platte River. Most wetlands in the project area are dominated by pale smartweed (Persicaria lapathifolia), narrowleaf cattail, broadleaf cattail (Typha latifolia), and cosmopolitan bulrush (Schoenoplectus maritimus). The wetlands and open water areas are shown on Figures 2a through 2m and described in more detail below. Photo points of the project area are also shown on Figures 2a through 2m, and the photo log is in Appendix A. For the purpose of organizing this report, three areas were identified that encompass the project area (Figure 1): the western portion of the project area is referred to as the Wattenberg Lakes (WL) area, the eastern portion of the project area is referred to as the South Platte Valley (SPV) area, and the South Platte River and Huett Ditch themselves are referred to as the South Platte River (SPR) and the Huett Ditch (HD) respectively.

Wetland Delineation Report Wattenberg Lakes and South Platte Valley Weld County, Colorado Methods Wetland Delineation On June 13, 2022 and August 2, 2022, Moneka Worah, Courtney Marne, Heidi Gerstung, Anna Wistrom, Emma Clary, Kelly McMillen, and Parker Waterman with ERO surveyed the project area for potential isolated wetlands, jurisdictional wetlands, and other WOTUS (2022 field survey). Prior to the 2022 field survey, ERO reviewed U.S. Geological Survey quadrangle topographic maps and aerial photography to identify mapped streams and areas of open water that could indicate wetlands or WOTUS. ERO conducted the wetland delineation following the methods for routine on -site wetland determinations in areas of less than 5 acres as described in the 1987 Corps of Engineers Wetlands Delineation Manual (1987 Manual) (Environmental Laboratory 1987), and used methods in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Great Plains Region (Version 2.0) (Corps 2010), to record data on vegetation, soils, and hydrology on routine determination forms (Appendix B). The Corps defines wetlands as "areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas" (33 Code of Federal Regulations 328.2(c)). Wetland boundaries were determined by a visible change in vegetation community, soils, topographic changes, and other visible distinctions between wetlands and uplands. The wetland indicator status of plant species was identified using the National Wetland Plant List (Corps 2020), taxonomy was determined using Flora of Colorado (Ackerfield 2015) and Colorado Flora: Eastern Slope (Weber, Wittmann, and Muller-Wille 2012), and nomenclature was determined using the PLANTS Database (USDA, NRCS 2022). Commonly occurring plant species in the project area, including the wetland indicator status, are listed in Appendix C. If present, hydric soils were identified using field observation for hydric soil indicators accepted by the Corps. Soil data were not always collected if hydrophytic vegetation and hydrology were present and did not appear altered (Environmental Laboratory 1987). In addition, soil data were not collected in conditions where there was a clear lack of hydrology and hydrophytic vegetation indicators. Where soil data were collected, a Munsell soil color chart was used to determine soil color. Intermittent, ephemeral, and perennial drainages with characteristics of a defined streambed, streambank, ordinary high water mark (OHWM), and other erosional features also were identified. The OHWM identifies the lateral jurisdictional limits of nonwetland WOTUS. Federal jurisdiction over nonwetland WOTUS extends to the OHWM, defined in 33 Code of Federal Regulations 328.3 as "the line on the shore established by fluctuations of water and indicated by physical characteristics such as a clear, natural line impressed on the bank, shelving, changes in the character of the soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas." The Corps defines "stream bed" as "the substrate of the ERO Project #22-193 18 ERO Resources Corporation Wetland Delineation Report Wattenberg Lakes and South Platte Valley Weld County, Colorado stream channel between the OHWMs. The substrate may be bedrock or inorganic particles that range in size from clay to boulders." The boundaries of identified wetlands and other characteristics of potential WOTUS were mapped using a Trimble Global Positioning System (GPS) unit. Data were differentially corrected using the CompassCom base station. All differential correction was completed using Trimble Pathfinder Office 5.4 software. GPS data were incorporated using ESRI® ArcGIS Desktop software. Additionally, where appropriate, wetlands were drawn on georectified aerials and then digitized. Wetland Classification Delineated wetlands were classified according to the U.S. Fish and Wildlife Service's Cowardin classification system (Cowardin et al. 1979) combined with a hydrogeomorphic (HGM) approach (Brinson 1993). The HGM approach assesses the physical, biological, and chemical functions of wetlands based on their geomorphic setting, water source, and hydrodynamics. HGM classes found in Colorado are mineral soil flats, organic soil flats, riverine, lacustrine fringe, slope, and depressional. The Cowardin classification uses a hierarchical structure of systems, subsystems, and classes to classify both wetlands and deepwater habitats. Wetlands with persistent or nonpersistent vegetation are classified in the Cowardin system as palustrine, which typically includes wetlands referred to as marshes, fens, wet meadows, and sloughs. The palustrine system also includes small, shallow, permanent, or intermittent water bodies such as ponds. Palustrine wetlands may be situated shoreward of lakes and river channels, on river floodplains, in isolated catchments, or on slopes (Cowardin et al. 1979). Under the palustrine system, wetlands are classified as emergent (erect, rooted, herbaceous, and usually perennial hydrophytes that remain standing until at least the next growing season), scrub -shrub (woody vegetation less than 20 feet tall), or forested (woody vegetation 20 feet or taller). In wetlands where more than one wetland type occurs, the wetland type of the largest area is used. For example, an area that is predominantly palustrine emergent wetlands but also contains a small amount of palustrine scrub -shrub wetlands would be categorized as palustrine emergent wetlands. Because of the limited occurrence of the smaller -sized wetland types within the larger wetland polygons, these areas were not separated out within the delineated polygons. The Cowardin riverine system includes wetlands and deepwater habitats contained within a channel, except wetlands dominated by trees, shrubs, and emergent vegetation. The riverine system usually contains flowing water and is bounded on the landward side by uplands, channel banks, or other wetlands. Within the riverine system, wetlands are divided into the tidal, lower perennial (low gradient and slow water), upper perennial (high gradient and fast water), and intermittent subsystems. Within these subsystems, riverine wetlands are further classified as unconsolidated bottom, aquatic bed, streambed, rocky shore, unconsolidated shore, and emergent wetland (nonpersistent). During the wetland delineation, ERO classified the wetlands as palustrine emergent and palustrine scrub -shrub. ERO Project #22-193 19 ERO Resources Corporation Wetland Delineation Report Wattenberg Lakes and South Platte Valley Weld County, Colorado Jurisdictional Assessment To assist the Corps in making a preliminary jurisdictional determination, ERO reviewed the proximity and potential surface water connection of wetlands to known jurisdictional WOTUS using aerial photo interpretation, landowner information, and information from the wetland survey. Within the project area, wetlands were distinguished as isolated, abutting or adjacent to a TNW, or abutting or adjacent to a tributary to a TNW. Abutting wetlands are not separated from a TNW or tributary by uplands or a berm, dike, or similar feature. Adjacent wetlands are bordering, contiguous to, or neighboring a TNW or tributary and may be separated from a TNW or tributary by uplands or a berm, dike, or similar feature. Wetlands or waters that have a surface water connection to the South Platte River may provide more than a speculative or insubstantial effect on the physical, biological, and/or chemical integrity of a TNW. The following sections contain information on potential surface water connections of wetlands and other waters in the project area. Description of Wetlands and Other Waters ERO assessed the project area for wetlands and other waters as described below. Data were collected from various locations in the project area to document the characteristics of uplands and wetlands and the transition areas between them. Each data point was given a label that corresponds to a location shown on Figures 2a through 2m and routine wetland determination forms in Appendix B. The following sections contain information on potential surface water connections of wetlands and other waters in the project area. Table 1 provides a summary of the mapped areas, including the Cowardin classification and HGM class for each wetland. Approximately 89.171 acres of gravel pond, 0.344 acre of open water, 13.444 acres of OHWM, and 35.229 acres of wetlands occur in the project area (Table 1; Figures 2a through 2m). Streams and Open Water The project area is in Hydrologic Unit 101900030409. During the 2022 field survey, the following areas of streams/open water were identified in the project area: the South Platte River, nine gravel ponds, three drainages, and two open waters. The South Platte River (SPR OHWM 1) generally flows from south to north through the southwest section of the eastern portion the project area (Photo 1; Figure 2i). The South Platte River consists of a 130- to 200 -foot -wide channel, is considered a TNW, and is a known WOTUS. Other areas of open water in the project area include WL Gravel Pond 1 (Photo 2; Figures 2a and 2b), WL Gravel Pond 2 (Figure 2d), WL Gravel Pond 3 (Photo 15; Figure 2k), and SPV Gravel Ponds 1 through 7 (Photos 3 and 4; Figures 2e through 2j). The gravel ponds in the project area were created because of the mining operations and have no connections to other WOTUS; they are isolated from TNWs. Three drainages were identified as SPV OHWM 1, 2, and 3 (Figures 2e, 2g, and 2h); these drainages connect flow from the SPV Gravel Ponds to other gravel ponds and/or isolated wetlands. SPV OHWM 1 through 3 are isolated from WOTUS. Two areas of open water were identified as SPV Open Water 1 and 2 (Photo 5; Figure 2g); these open water areas are surrounded by SPV Wetland 2 and SPV Wetland 7, respectively, and do not appear to have a downstream surface ERO Project #22-193 20 ERO Resources Corporation Wetland Delineation Report Wattenberg Lakes and South Platte Valley Weld County, Colorado connection to a known WOTUS. There is also one open water area along the Huett Ditch (HD OHWM 1) at the north end of the project area (Photo 16, Figure 2m). The Huett Ditch was relocated further east of the WL area in 2006; the original ditch was left in place until 2013 when it was impacted by construction of a slurry wall. The Huett Ditch has a surface connection to Lupton Bottom Ditch which connects to Big Dry Creek, a tributary of the South Platte River, and is therefore a WOTUS. Wetlands As discussed above in the Project Area Description, the wetlands in the project area were divided into three categories based on location and connection to surface waters. The WL Wetlands comprise the western side of the project area as seen in Figures 2a through 2d and Figure 2k and are a result of mining activity and excavation. Wetlands occur throughout Heutt Ditch in the project area (HD Wetland 1 through HD Wetland 6 (Figures 2k through 2m). The SPV Wetlands are located between US Hwy 85 and the South Platte River and are also associated with mining excavation activities, as seen in Figures 2e through 2j. The SPR Wetlands lie along the banks of the South Platte River as seen in Figures 21, Figure 2k, and Figure 2I and are a natural part of the South Platte River ecosystem. Wattenberg Lakes (WL) Wetlands WL Wetlands and Isolated Wetlands were distinguished from each other based on their size and relative connectivity to the landscape. WL Isolated Wetlands were located in small depressions, likely created by the disturbance and excavation from mining activities, whereas WL Wetlands were larger and likely created by impounding from roads, berms, and gravel ponds. WL Wetland 1 (data point [DP] 1 through DP5), seen in Figure 2a and Photo 6, is located southeast of the intersection of CR 23.5 and CR 4.5 and adjacent to WL Gravel Pond 1. WL Wetland 1 was designated as isolated in the Individual Permit (Corps File No. 200080189) for the Wattenberg Lakes Aggregate Mining project (Corps 2005). During the 2022 field survey, the primary source of surface water in WL Wetland 1 appeared to be from surface runoff from the row irrigation across CR 23.5. There are private properties to the north and south of WL Wetland 1. WL Wetlands 2, 3, and 4 (DP10 through DP12), seen in Figures 2a and 2b, are located on the east side of WL Gravel Pond 1 and are separated from the gravel pond by a berm. WL Wetlands 2 through 4 are in a low geomorphic position that runs between the berm and the surrounding disturbed uplands (Photo 7). WL Wetlands 5 and 6, WL Wetland 7 (DP13 and DP14), and WL Wetland 8, seen in Figure 2c, are located east of CR 23.5 and south of a private property (Photos 8 and 9). Portions of WL Wetlands 5 and 8 were not surveyed on foot due to property boundaries but were viewed from afar and on aerial imagery and assumed based on their similarities to WL Wetlands 6 and 7. WL Wetlands 5 through 8 are in a low geomorphic position bounded by CR 23.5 on the west, a private property to the north, and upland disturbed sites due to mining excavation on the east and south. WL Wetlands 6 and 7 are separated by an access road. WL Wetlands 5 through 8 may have a connection to WL Gravel Pond 2, seen in Figure 2d. WL Wetlands 9 through 11 are fringe wetlands associated with WL Gravel Pond 3 located near the southeastern boundary of the WL area (Photo 15, Figure 2k). ERO Project #22-193 21 ERO Resources Corporation Wetland Delineation Report Wattenberg Lakes and South Platte Valley Weld County, Colorado WL Wetlands 2 through 4 and WL Wetlands 5 through 8 occur in or near an old oxbow that was mapped as jurisdictional in the Wattenberg Lakes Aggregate Mining permit (Corps 2005). Based on the conditions observed during the 2022 field survey, the majority of the previously delineated oxbow wetlands have dried up. Annual groundwater monitoring in the project area, and specifically along the oxbow, indicate that mining and dewatering activities west of the slurry wall that begun at the end of 2017 and continued to the end of 2019, impacted groundwater levels (Applegate Group, Inc, 2022). Since the dewatering and mining activities ceased, groundwater levels in the oxbow have begun to rise again, and wetlands are beginning to reestablish. WL Wetland 5 was not included in the Wattenberg Lakes Aggregate Mining permit because it is outside of that project area's boundaries. Vegetation Emergent wetlands and one palustrine scrub -shrub wetland were delineated in the WL project area abutting CR 23.5 and the mining activity west of the South Platte River. Data points were collected in WL Wetlands 1, 4, and 7 as well as in the adjacent uplands. The characteristics of the remaining WL Wetlands 2, 3, 5, 6, and 8 were observed to be similar to the data points described here, so it can be inferred that all WL Wetlands 1 through 8 had similar vegetation communities to the ones described here. These wetlands were dominated by curly dock (Rumex crispus), sandbar willow, reed canary grass (Phalaris arundinacea), spotted lady's thumb (Persicaria maculosa), and broadleaf cattail. DP4 located in WL Wetland 1 was classified as palustrine scrub -shrub, whereas the rest of the WL Wetlands data points were classified as palustrine emergent. At DP4, DP10, DP11, and DP13, the vegetation met the rapid test for hydrophytic vegetation. At DP2 the vegetation passed the dominance test for hydrophytic vegetation. DP1, DP3, DP5, DP12, and DP14 consisted primarily of upland species and did not meet the requirements for hydrophytic vegetation. Soils Soil types in the project area were identified by the NRCS Soil Surveys for Weld County, Colorado. The NRCS mapped one primary soil association for WL Wetlands 1 through 8 (USDA 2022b). Most of the soils were mapped as Aquolls and Aquents, gravelly substratum, typically found in swales, streams, and floodplains. Two less prevalent soil associations were mapped in the project area. The soils in the northern portion of WL Wetland 1 were mapped as Altvan loam, 0 to 1 percent slopes, typically found in terraces. The soils in the southern portion of WL Wetland 1 were mapped as Dacono clay loam, 0-1 percent slopes, and typically found in terraces. The recent mining activity has altered this significantly, and therefore the soil mapping units may no longer apply. Field observation revealed that the soils primarily consist of sandy loams, loams, and silt loams within the upper 12 inches of the soil profile. Soils were not sampled at DP2 because it was assumed based on the hydrophytic vegetation and hydrology that the soils would be hydric. DP4 met the requirements for the redox dark surface and redox depressions indicators with a matrix color of 10YR 2/1, redox depletions N 2.5/-, and redox concentrations in the form of pore linings with a color of 10YR 3/4. DP11 met the indicator for hydrogen sulfide presence. DP13 had very sandy/gravelly soils that were inundated and therefore assumed to meet the hydric indicator status. Nonhydric soils were assumed at ERO Project #22-193 22 ERO Resources Corporation Wetland Delineation Report Wattenberg Lakes and South Platte Valley Weld County, Colorado DP5, DP12, and DP14 based on a lack of hydrophytic vegetation and wetland hydrology indicators and the abrupt transition to uplands. DP1 and DP3 did not meet any requirements for hydric soil indicators. DP10 met the redox dark surface indicator but did not meet the wetland hydrology indicator requirements. Hydrology Primary hydrologic indicators observed across the WL Wetlands included water -stained leaves (DP2), oxidized rhizospheres on living roots (DP2), high water table (DP4, DP11, and DP13), saturation (DP11 and DP13), surface water (DP4), and hydrogen sulfide odor (DP11). Secondary indicators observed across the WL Wetlands included saturation visible on aerial imagery (DP2), geomorphic position (DP2), and the FAC-neutral test (DP2, DP4, DP11, and DP13). No hydrologic indicators were observed in the upland data points. Wattenberg Lakes (WL) Isolated Wetlands WL Isolated Wetlands 1 and 2, seen in Figure 2a, are located between CR 23.5 and the southwest corner of WL Gravel Pond 1 in a highly disturbed, upland area (Photo 10). WL Isolated Wetlands 1 and 2 were not mapped as part of the Wattenberg Lakes Aggregate Mining permit (Corps 2005). WL Isolated Wetland 3 (DP6 and DP7; Photo 11), WL Isolated Wetlands 4 through 8, WL Isolated Wetland 9 (DP8 and DP9), and WL Isolated Wetland 10 (Photo 12), seen in Figure 2b, are located east of WL Gravel Pond 1 in a mostly upland, disturbed area. WL Isolated Wetlands 3 through 10 appear to occur in or near an old oxbow that was mapped as jurisdictional in the Wattenberg Lakes Aggregate Mining permit (Corps 2005). WL Isolated Wetlands 11 through 13 are in localized depressions in disturbed uplands between the Huett Ditch and WL Gravel Pond 3 (Figure 2k). Currently, each of the WL Isolated Wetlands are independently located in low geomorphic positions relative to the surrounding area and do not have a connection to any other wetlands or waters. Vegetation Emergent wetlands were delineated in the WL project area abutting CR 23.5 and the mining activity west of the South Platte River. Data points were collected only in WL Isolated Wetlands 3 and 9 and in the adjacent uplands. The characteristics of the remaining WL Isolated Wetlands 1, 2, 4 through 8, and 10 were observed to be similar to the data points described here, so it can be inferred that all WL Isolated Wetlands 1 through 10 had the same vegetation communities. These isolated wetlands were dominated by pale smartweed, Baltic rush (Juncus balticus), and saltgrass (Distichlis spicata). Other vegetation included blue-eyed grass (Sisyrinchium sp.) and lady's thumb (Persicaria maculosa). At DP6 and DP8, the vegetation passed the rapid and dominance tests, respectively, for hydrophytic vegetation. DP7 and DP9 consisted primarily of upland species and did not meet the requirements for hydrophytic vegetation. Soils Soil types in the project area were identified by the NRCS Soil Surveys for Weld County, Colorado. The NRCS mapped two primary soil associations for the WL Isolated Wetlands (USDA 2022b). Soils on the ERO Project #22-193 23 ERO Resources Corporation Wetland Delineation Report Wattenberg Lakes and South Platte Valley Weld County, Colorado east side of WL Gravel Pond 1 were mapped as Aquolls and Aquents, gravelly substratum, typically found in swales, streams, and floodplains. The soils west of WL Gravel Pond 1 adjacent to CR 23.5 were mapped as Dacono clay loam, 0-1 percent slopes, and typically found in terraces. The recent mining activity has altered this significantly, and therefore the soil mapping units may no longer apply. At DP6 soils contained a matrix color of 10YR 3/2 with 7.SYR 5/8 redox concentrations in the upper 7 inches with a silty clay loam texture. At DP6, soils met the redox dark surface indicator. At DP8 soils contained a matrix color of 10YR 2/1 with a sandy loam texture and 7.5YR 5/6 redox concentrations from 7 to 12 inches. At DP8 soils met the redox dark surface indicator. No hydric soil indicators were observed at DP7. DP9 met the requirements for the sandy redox indicator, but the lack of hydrophytic vegetation made it an upland. Hydrology Hydrology indicators were observed at DP6 and DP8. Primary indicators were observed including high water table, saturation, and oxidized rhizospheres on living roots. Secondary indicators were observed including the FAC-neutral test. Oxidized rhizospheres on living roots were identified in DP7 and DP9; however, a lack of hydrophytic vegetation prevented both points from being delineated as wetlands. Huett Ditch (HD) Wetlands HD Wetlands 1 through 6, seen on Figure 2k through 2m, are in the realigned Huett Ditch, along the eastern and northern boundary of the WL area (Photos 16 through 18). Throughout the project area, the majority of the Huett Ditch is approximately 20 feet wide and generally runs from south to north, then curves to the west at the northern boundary of the project area. At the far upstream and downstream end of Huett Ditch in the project area, HD Wetland 1 (Figure 2m) and HD Wetland 6 (Figure 2k), the wetlands are in more shallow depressions and are more spread out. Vegetation Emergent wetlands were delineated in the WL project area along the Huett Ditch. Data points were collected in HD Wetland 1 and 5 and in the adjacent uplands. The characteristics of the remaining HD Wetlands 2, 3, 4, and 6 were observed to be similar to the data points described here, so it can be inferred that the remaining HD Wetlands consisted of the same vegetation communities. The HD Wetlands were dominated by narrowleaf cattail, reed canarygrass, Canada thistle, with some curly dock. At DP25, DP26, DP30, and DP31, the vegetation passed the dominance test, for hydrophytic vegetation. DP24, DP27, and DP32 consisted primarily of upland species and did not meet the requirements for hydrophytic vegetation. Soils Soil types in the project area were identified by the NRCS Soil Surveys for Weld County, Colorado. The NRCS mapped the primary soil association for the HD Wetlands as Aquolls and Aquents, gravelly substratum, typically found in swales, streams, and floodplains. The recent mining activity and realignment of the Huett Ditch has altered soils in the area, and therefore the soil mapping units may no longer apply. ERO Project #22-193 24 ERO Resources Corporation Wetland Delineation Report Wattenberg Lakes and South Platte Valley • Weld County, Colorado At DP25 soils contained a matrix color of 10YR 2/2 with 7 percent 7.5YR 4/6 prominent redox concentrations in the upper 3 inches with a loam texture. From 3 through 9 inches in depth, the soils contained a mixed matrix color of 10YR 3/2 with 10 percent 7.5YR 4/6 prominent redox concentrations and 30 percent Gley 3/1. At DP26 soils contained a matrix color of 10YR 3/1 with a silty clay loam texture and 7.5YR 3/4 redox concentrations from 0 to 2 inches, then a matrix color of 10YR 3/2 with 10 percent 7.5YR 4/6 prominent redox from 2 to 14 inches, and from 14 to 16 inches there was a matrix color of 10YR 3/1 with a sandy texture. At DP30 soils contained a matrix color of 10YR 2/1 with 7.5YR 4/6 redox concentrations from 0 to 9 inches, with 15 percent redox concentrations from 0 to 7 inches and 30 percent redox concentrations from 7 to 9 inches. At DP31 soils contained a matrix color of 10YR 3/1 with 7 percent 7.5YR 4/6 prominent redox concentrations in the upper 12 inches with a clay texture. From 12 through 15 inches in depth, the soils contained a matrix color of 10YR 3/1 with 40 percent 5YR 3/4 prominent redox concentrations. The soils at DP25, DP26, DP30, and DP31 all met the redox dark surface indicator. No hydric soil indicators were observed at DP24, DP27, or DP32. Hydrology Hydrology indicators were observed at DP25, DP26, DP30, and DP31. Primary indicators were observed including a high water table, saturation, and oxidized rhizospheres on living roots. Secondary indicators were observed including saturation on visible aerial imagery, geomorphic position, and the FAC-neutral test. Two secondary hydrology indicators were identified in DP24; however, a lack of hydrophytic vegetation and hydric soils prevented this DP from being delineated as wetlands. South Platte Valley (SPV) Wetlands SPV Wetlands and Isolated Wetlands were distinguished from each other by their connectivity to gravel ponds and open water bodies. Any wetlands connected to gravel ponds or open water were called wetlands, and any wetlands that were not connected were called isolated wetlands. All the wetlands and isolated wetlands describedin this section were a result of mining excavation. SPV Wetland 1 (DP17 through DP20; Photo 3), seen in Figure 2e, is associated with SPV Gravel Pond 1. SPV Wetland 2 (DP15 and DP16; Photo 5) and SPV Wetland 3 (Photo 4), seen in Figures 2e and 2g, are associated with SPV Gravel Pond 2 and SPV Open Water 1. SPV Wetland 4, seen in Figures 2e and 2g, is associated with SPV Gravel Pond 4. SPV Wetland 5, seen in Figure 2e, is a small fringe wetland associated with SPV Gravel Pond 3. SPV Wetland 6, seen in Figure 2f, is a fringe wetland along the north side of SPV Gravel Pond 5. SPV Wetland 7, seen in Figure 2g, is associated with SPV Open Water 2. SPV Wetland 8, seen in Figure 2g, is associated with SPV Gravel Pond 6. SPV Wetlands 9, 10, 11, 12, and 13, seen in Figures 2g through 2j, are associated with SPV Gravel Pond 7. Vegetation Emergent wetlands were delineated in the SPV project area abutting US Hwy 85 and the mining activity east of the South Platte River. Data points were collected only in SPV Wetlands 1 and 2 as well as in the adjacent uplands. The characteristics of the remaining SPV Wetlands 3 through 13 were observed to be similar to the data points described here, so it can be inferred that all SPV Wetlands 1 through 13 had ERO Project #22-193 25 ERO Resources Corporation Wetland Delineation Report Wattenberg Lakes and South Platte Valley Weld County, Colorado the same vegetation communities. The wetland fringes along the gravel ponds were dominated by broadleaf cattail and cosmopolitan bulrush. Other vegetation observed included Nebraska sedge (Carex nebrascensis), rough cocklebur (Xanthium strumarium), sandbar willow, and narrowleaf cattail (Typha angustifolia), among others. At DP16 and DP17, the vegetation met the dominance test for hydrophytic vegetation. DP18 and DP19 passed the dominance test for hydrophytic vegetation; however, neither data point had the soils or hydrology to be considered a wetland. DP15 and DP20 were primarily composed of upland species. Soils Soil types in the project area were identified by the NRCS Soil Surveys for Weld County, Colorado. The NRCS mapped one primary soil association for the SPV Wetlands (USDA 2022b). DP15 through DP20 were all mapped under the Aquolls and Aquents, gravelly substratum, typically found in swales, streams, and floodplains. This map unit is associated with the adjacent South Platte River; however, due to the recent mining activity, this soil mapping may no longer apply. Soils were not sampled at DP16 and DP17 because they were assumed hydric based on the vegetation and hydrology. Nonhydric soils were assumed at DP18 based on a lack of wetland hydrology indicators and the abrupt transition to uplands. No hydric soil indicators were observed at DP15, DP19, or DP20. Hydrology Hydrology indicators were observed at DP15 through DP17. Secondary hydrologic indicators were observed at DP16, which included geomorphic position and the FAC-neutral test. Both primary and secondary hydrologic indicators were observed at DP17; this included high water table at a depth of 4 inches, saturation at the surface, and the FAC-neutral test. Hydrologic indicators were observed at DP15; however, due to the lack of hydrophytic vegetation and soils, DP15 was considered upland. DP18 through DP20 did not meet the required wetland hydrology indicators. South Platte Valley (SPV) Isolated Wetlands SPV Isolated Wetlands 1, 2 (DP22), 3, 4, and 5 and 6 (DP21), seen in Figures 2e and 2f, are the result of mining excavation and fill activities (Photos 13 and 14). SPV Isolated Wetland 2 was formerly a gravel pond that has since been filled in. SPV Isolated Wetlands 7 and 8 (DP23), seen in Figure 2g, are constrained by an access road and Gravel Pond 6 and are likely the result of mining excavation disturbance. SPV Isolated Wetlands 9, 10, 11, and 12, seen in Figure 2h, were located close to the active mining area and were constrained by US Hwy 85 and access roads. These isolated wetlands are likely the result of mining excavation activity. Vegetation Emergent wetlands were delineated in the SPV project area abutting US Hwy 85 and the mining activity east of the South Platte River. Data points were collected only in SPV Isolated Wetland 2 and in uplands adjacent to SPV Isolated Wetlands 5, 6, 7, and 8. The characteristics of the remaining SPV Isolated Wetlands 1, 3, 4, 9, 10, 11, and 12 were observed to be similar to the data points described here, so it can be inferred that all SPV Isolated Wetlands 1 through 12 had the same vegetation communities. ERO Project #22-193 26 ERO Resources Corporation Wetland Delineation Report Wattenberg Lakes and South Platte Valley Weld County, Colorado These isolated wetlands were dominated by pale smartweed. At DP22, the vegetation met the rapid test for hydrophytic vegetation. DP21 consisted primarily of upland species and did not meet the dominance test for hydrophytic vegetation. DP23 did meet the rapid test for hydrophytic vegetation; however, the lack of hydric soils prevented it from being called a wetland. Soils Soil types in the project area were identified by the NRCS Soil Surveys for Weld County, Colorado. The NRCS mapped two primary soil associations for the SPV Isolated Wetlands (USDA 2022b). In the majority of the SPV project area, the soils were mapped as Aquolls and Aquents, gravelly substratum, typically found in swales, streams, and floodplains. A minority of the soils in the central portion of the SPV project area were mapped as Ellicott -Ellicott sandy -skeletal complex, 0 to 3 percent slopes, rarely flooded and are typically found in drainageways. The recent mining activity has altered this significantly. Soils were not sampled at DP22 because it was assumed hydric based on the presence of hydrophytic vegetation and wetland hydrology indicators. No hydric soil indicators were observed at DP21 or DP23. Hydrology Hydrology indicators were observed at DP22. Secondary indicators were observed including surface soil cracks, geomorphic position, and the FAC-neutral test. No hydrologic indicators were observed at DP21. Secondary indicators including surface soil cracks and the FAC-neutral test were observed at DP23; however, a lack of hydric soils prevented this area from being delineated as a wetland. South Platte River (SPR) Wetlands SPR Wetlands described in this section were within the floodplain of the South Platte River. These wetlands were not delineated directly due to access and safety issues; however, connectivity to the South Platte River combined with observations from afar and aerial imagery provided enough information to delineate these wetlands. SPR Wetlands 1, 2, 3, and 4, seen in Figure 2i, and SPR Wetlands 6, 7, 8, and 9, seen in Figures 2I and 2m, are associated with SPR OHWM 1. SPR OHWM 1 represents the South Platte River. SPR Wetlands 1 and 3 are located on the east bank of the river, and SPR Wetlands 2, 4, and 6 through 10 are located on the west bank. Vegetation Emergent wetlands were identified in the project area abutting the banks of the South Platte River. The SPR Wetlands 1 through 4 fringes along the banks of the South Platte River were not surveyed at the time of the site visit due to access issues; however, due to the hydrology of the river, a hydrophytic wetland vegetation regime can be assumed. SPR Wetlands 5 through 9 along the west bank were able to be accessed with DP28 being collected in SPR Wetland 5, and DP29 collected in the adjacent uplands. Emergent and scrub -shrub wetlands were observed in narrow fringes along the South Platte River. At DP28, dominant vegetation included plains cottonwood and crack willow (Salix fragilis) trees, sandbar ERO Project #22-193 27 ERO Resources Corporation Wetland Delineation Report Wattenberg Lakes and South Platte Valley Weld County, Colorado willow, reed canarygrass, and Canada thistle. DP28 met the dominance test for hydrophytic vegetation. DP29 consisted primarily of upland species and did not meet any indicators for hydrophytic vegetation. Soils Soil types in the project area were identified by the NRCS Soil Surveys for Weld County, Colorado. The NRCS mapped two primary soil associations for the SPR Wetlands (USDA 2022b). The soils on the west side of the South Platte River were mapped as Aquolls and Aquents, gravelly substratum, typically found in swales, streams, and floodplains; this includes SPR Wetlands 2 and 4 through 9. The soils on the east side of the South Platte River were mapped as Ellicott -Ellicott sandy -skeletal complex, 0 to 3 percent slopes, rarely flooded and are typically found in drainageways; this includes SPR Wetlands 1 and 3. The area within the South Platte River is mapped as Open Water. At DP28 soils contained a matrix color of 10YR 3/3 with 2 percent 7.5YR 5/6 redox on coated sand grains the first inch with a sandy texture. From 1 through 3 inches in depth, the soils contained a matrix color of 10YR 4/3 with 7 percent 7.5YR 4/6 redox on coated sand grains, and from 3 to 14 inches, the soils contained a matrix color of 10YR 3/2 with 10 percent 7.5YR 4/6 redox coated sand grains with a sandy texture. The soils at DP28 met the sandy redox hydric soil indicator. Soils were not sampled at DP29 because it was assumed based on the lack of hydrophytic vegetation and hydrology that the soils would be nonhydric. Hydrology Hydrology indicators were observed at DP28. Secondary indicators were observed including saturation visible on aerial imagery, geomorphic position, and the FAC-neutral test. No hydrologic indicators were observed at DP29. Hydrology indicators were not observed directly at SPR Wetlands 1 through 4 due to access issues; however, primary hydrologic indicators likely included saturated soil conditions within 12 inches of the ground surface. Secondary hydrologic indicators likely included drainage patterns and the geomorphic position.

Palustrine emergent Depression human impounded Total Wetlands 35.231 - Total 138.189 Jurisdictional Assessment ERO believes the SPR Wetlands, which abut the South Platte River, WL Wetlands 2 through 8, which lie in an old oxbow of the South Platte River, and the HD Wetlands 1 through 6 would be considered jurisdictional. The SPR is a known WOTUS. WL Wetland 2 through 8 are identified on the National Wetlands Inventory mapping as wetlands and were designated as jurisdictional in the Wattenberg Lakes Aggregate Mining project permit. As of the 2022 site visits, these wetlands no longer appear to be connected by a significant nexus in accordance with the Rapanos guidelines, and ERO therefore believes these features could be considered nonjurisdictional. The Huett Ditch has a surface connection to Lupton Bottom Ditch which connects to Big Dry Creek, a tributary of the South Platte River, and is therefore a WOTUS. ERO believes all other wetlands and water bodies identified by this report in the project area could be considered nonjurisdictional because of their lack of a direct surface connection to a known WOTUS and/or development from gravel mining operations. Because the South Platte River and its associated wetlands are considered jurisdictional, any impacts on the South Platte River or SPR Wetlands would require a Section 404 permit. ERO believes the WL and SPV water bodies and wetlands identified in this report are nonjurisdictional because they were created in association with the mining excavation activities or lack a connection to a known WOTUS. Additionally, the isolated wetlands have no nexus to a known WOTUS and are therefore also believed to be nonjurisdictional. ERO is assisting Holcim-WCR, Inc., with a compensatory wetland mitigation and monitoring plan for submittal to the Corps and will incorporate information from this report to supplement the plan.

Attached is the formal structure agreement letter and package. Please note any corrections or additional information on the list of structures, and then sign and notarize the Agreement and return the Agreement as soon as possible, preferably no later than Monday, June 5,2023. If you have any questions, please let me know. Holcim-WCR, Inc. (Holcim) is planning to conduct limited mining and to complete reclamation of their Wattenberg Lakes Mine in Weld County, Colorado under a permit amendment with the Colorado Division of Reclamation, Mining and Safety (DRMS). The property is located in portions of Section 25, 30 and 36, Township 1 North, Range 67. West of the 6th P.M., Weld County, Colorado. Holcim is applying to the DRMS for an amendment to their current 112 Reclamation Permit. We have identified one or more structures that we believe you own within 200 feet of the affected area associated with this Permit. As part of their application and planning, Holcim has taken steps to prevent any impact to your structure(s). Consistent with DRMS Construction Materials Rule 6, Section 6.4.20, Holcim, as the permit applicant, shall identify permanent man-made structures within 200 feet of the affected area of the proposed mine site and request a notarized agreement with each structure owner, indicating that Holcim will compensate the structure owner for any damage to the structure(s) caused by Holcim. Attached to this letter you will find the Structure Agreement. The Agreement assures you that Holcim will take responsibility for damage to your structure(s) if Holcim's mining or reclamation activities unexpectedly affect your structure(s). The DRMS provided the language used in the Structure Agreement. Also attached to this letter is a draft copy of the Location/Index Map, Mining Plan Map, and the Structures Map associated with the Wattenberg Mine application to help you understand the location of your structures in relation to the permit boundary and Holcim's planned mining. Once received, Holcim will sign the agreement; then we will send you a fully executed copy for your records. Thank you for your consideration.

From: Ted Deere, PE - Project Geotechnical Engineer, Tetra Tech Fred Charles, PE - Project Manager, Tetra Tech Date: May 3, 2023 Subject: Wattenberg Lakes Amendment, Pond 1 Reclamation Slope Stability This Technical Memorandum summarizes the analysis performed to evaluate the slope stability of proposed reclamation slopes for the Wattenberg Mine, Pond 1 Reclamation. Guidance from the Mine Land Reclamation Board (MLRB) May 2018 policies was utilized for the recommended minimum factors of safety for slope stability analyses for operations and reclamation. The setbacks and slope geometry reported in this memo represent the minimum requirements. Setback may need to be greater and or slopes to be flatter based on regulatory requirements as needed. 1.0 SITE LAYOUT AND DESCRIPTION Pond 1 of the Wattenberg Mine is located on an alluvial terrace just west of the South Platter River, less than 1 mile south of the Town of Wattenberg. The Pond 1 site is adjacent to the southwest corner of existing Pond 3. Holcim - WCR, Inc. (Holcim) plans to mine sand and gravel from a portion of the Pond 1 area within the Wattenberg Lakes site. Holcim plans to reclaim Pond 1 Mine as a below -grade lined reservoir meeting seepage requirements of the State Engineer of Colorado. 2.0 GEOLOGY AND FIELD INVESTIGATIONS Field investigations on the Wattenberg Mine, including at Pond 1 were previously performed by Aggregate Industries (1997) Tetra Tech (2005 and 2011). Locations of relevant borings near Pond 1 from prior site investigations are presented in Attachment A. Addition information on the Wattenberg Mine site, including summary boring logs are provided in Attachment B (the Pond 3 Reclamation Slope Plan Set from 2013). Data obtained from the exploratory borings at the site indicate that four units were encountered throughout the site, which includes (1) overburden, (2) sand and gravel with localized interbedded mud lenses, (3) claystone bedrock, and (4) sandstone bedrock. A detailed description of each unit is described below: The Unit 1 overburden materials range from very loose to medium dense clayey sands to soft to stiff sandy clays and silt. Laboratory testing indicates that these materials, with a few exceptions, are suitable as reclamation slope fill. The testing resulted in percent passing the 200 -sieve ranging from 26 to 92. Samples tested for Atterberg Limits resulted in Liquid Limits and Plasticity Indices ranging from non -plastic to 67 and non -plastic to 37 respectively. Highly plastic soils can likely be mixed with other less plastic soils to be suitable for reclamation slope fill. Unit 2 consists of the sand and gravel with local lenticular mud lens. The sand and gravels are actively mined for aggregate products. This unit generally consists of medium to coarse grained sand and gravel and is typically loose to dense. The unit is highly permeable and contains groundwater. Laboratory testing (primarily gradations and Atterberg limits) on the mud lens indicates these soils are suitable for reclamation slope fill. Units 3 (claystone) and 4 (sandstone) are the bedrock encountered underlying unit 2. Bedrock does not crop out at the site, however review of Colton (1978) indicates the near surface bedrock at the site is the likely the Denver and/or Arapahoe Formations (mapped as undifferentiated). The Tetra Tech borings at the site indicate the bedrock is moderately hard to hard. The bedrock encountered in the borings had a relatively thin weathered zone on the order of one or two feet thick. This weathered zone will need to be stripped in order that the reclamation slope is on a firm bedrock foundation.

The software performs a limit equilibrium slope stability analysis to compute the factors of safety for several failure surfaces including the critical surface which has the lowest factor of safety. All failure surfaces were calculated using Spencer's method, with the failure surfaces occurring from the crest of the slope. Analyzed Sections Three sections were analyzed to evaluate the reclamations slopes at the site. A 10 -foot crest width of the reclamation fill and a 25 -foot offset of the mine slope to the slurry are shown in each section. A maximum section for non -critical structures and a typical section was analyzed. Additionally, a maximum section near critical structure was analyzed since there is overhead electric within approximately 30 feet of the northeast corner of Pond 1. A total of twelve slope stability models were prepared to evaluate proposed slopes as shown in Attachment C. Each section was performed under the following loading scenarios in consideration of good practices for mine reclamation slopes: • Empty Reservoir • Full Reservoir • Rapid Drawdown • Seismic Full Reservoir with a t.lg horizontal acceleration Below is a description of the three model sections: Section 1: Typical section, 26 ft reclamation slope (non -critical structure) Section 1, (Figures 1 to 4 in Attachment C) Exploratory boring data indicates the depth to bedrock typically 26 feet or less. The grade modeled for the reclamation slope was 3H:1V and the highwall is assumed to be 0.5H:1V. Section 2: Maximum section, 33 ft reclamation slope (non -critical structure) Section 2, (Figures 5 to 8 in Attachment C) Exploratory boring data indicates the depth to bedrock may be as deep as 33 feet near the maximum section. The grade modeled for the reclamation slope was 3H:1V and the highwall is assumed to be 0.5H:1V. A 10 -foot -wide, 7 -foot -tall, free draining toe berm with a 3H:1: slope was modeled to increase stability at this section. Section 3: Maximum section, 33 ft reclamation slope near critical structure Section 3, (Figures 9 to 12 in Attachment C) has the exact same geometry as Section 2, however Sections 3 assumes that a drain has been installed within the slope to help dissipate the water out of the slope during a reservoir drawdown, which will further increase the factor of safety. Exploratory boring data indicates depth the bedrock may be as deep as 33 feet near the maximum section, which may occur near the location of the overhead electric on the northeast side of the pond. Material Strength Properties Material properties used in the analysis were based on boring logs in the area from Aggregate Industries (1997) and Tetra Tech (2007 and 2011), experience from similar materials in the area (including Pond 3, see Attachment C) and review of typical published strength values for soils and weak sedimentary rock. A cement bentonite slurry wall was modeled as cohesionless material to ensure that there are no failure plans that extend behind the slurry wall which could result in a slope failure through it.

Backfill will be placed in lifts and compacted to a minimum of 95% of maximum dry density as determined by standard Proctor. Project specifications have not been developed at this time; however, based on existing information for the site, it is anticipated that overburden obtained from stripping and mud lenses would be suitable. In some cases, mixing of highly plastic overburden with less plastic overburden will be necessary. It is also anticipated that the weathered zone of the bedrock will be stripped (1' minimum) before the reclamation slope fill is approved for placement. The most permeable (relatively free draining) material should be used to construct the small toe berms in the vicinity of anticipated maximum section(s). If there is sufficient material available onsite or imported to the site, the reclamation slope liner can be constructed around the entire Pond 1 mine. Any imported material will need to be tested to evaluate if the material is suitable for reclamation slope fill, since there may not be enough mined overburden or mud lens material to construct the entire reclamation slope. If such is the case, it may be necessary to import material or potentially borrow bedrock. Additional slope stability analyses should be performed to enable Tetra Tech to make suitable slope recommendations and evaluate offsets from the reclamation slope toe to potential bedrock borrow areas. Alternatively, a 3:1 slope of unmined sand and gravel slope may be designed if enough suitable borrow materials are not available to construct reclamation slopes. Static and seismic stability analyses were performed for each of the sections described above. Seismic analysis accounts for the effects of horizontal acceleration experienced during an earthquake. The horizontal acceleration used was 0.1 g and corresponds to an event with a 2% probability of exceedance in 50 years (return interval of 2,475 years). The acceleration value was obtained from United States Geological Survey Unified Hazard Tool which considers the soil/rock classification of the upper 100 feet (Classification C selected) and location of the site. The following minimum factor of safety criteria requirements from the DRMS were used: • The minimum factor of safety for the static analysis (non -critical structures) is 1_3 • The minimum factor of safety for the seismic analysis (non -critical structures) is 1.15 • The minimum factor of safety (near critical structures) for the static analysis 1_5 • The minimum factor of safety (near critical structures) for the seismic analysis is 1_3 TETRA TECH Page 3)5 Wattenberg Lakes Amendment, Geotechnical Stability May 2023 Slope Stability Results The tables below present stability model results with graphical output presented in Attachment C. Model results indicate that the minimum required factor of safety is achieved for the reclamation slope models and appropriate setbacks to a slurry wall are presented for the relatively steeper mine slope.

TETRA TECH Page 4(5 Wattenberg Lakes Amendment, Geotechnical Stability May 2023 4.0 LIMITATIONS The findings presented in this memorandum are based on information from previous investigations at the site and strength parameters of the modeled materials assumed from typical published values. Tetra Tech should be contacted if the mining plans change or if the subsurface conditions vary from the descriptions here as reevaluation may be necessary to investigate the potential effects of the changes on the factors of safety for the critical structures determined in this evaluation. Factors of safety for this evaluation were limited to reclamation slopes and were not an evaluation of the overall mining highwall or mine slopes. Fred Charles, P.E. Project Manager Ted Deere, P.E.
