Water will be purchased from a local source and trucked on site for consumptive uses. Engineering Comments 1, Provide a Traffic Impact Statement per WCECC Manual The Marcovich site, acting as a satellite pit from the Chaver's Mining Resource, will generate no public traffic as it is accessed only with mining equipment and personnel from the Chaver's site. The Chaver's Pit has its own CDOT access permit and traffic study. Because of this, a traffic impact statement is not necessary. The access and impact of traffic is an unrelated matter to the Marcovich land use permit. Additionally, the Weld County Code does not have any information on a 'Traffic Impact Statement', as it only defines Traffic Impact Analyses, Traffic Narratives, and Traffic Impact Studies. Please provide further clarification on what the County wants in regard to a Traffic Impact Statement for the Marcovich site if it is still deemed necessary despite the lack of public traffic. 2. Provide a storm water management plan per wCECC Manual A Stormwater Management Plan is provided with this response. Regards, Sydney Connor Lewicki & Associates, PLLC (719)323-9867 ben@lewicki.biz Marcovich Adequacy #1 December 2024 3 L Lewicki & Associates Attachments • USR Submittal Content Guide • USR Submittal Items (Folder Shared) • Marcovich SWMP Marcovich Adequacy #1 December 2024 4 L Lewicki & Associates USR Planning Questionnaire 1. Explain the proposed use and business name: The proposed Marcovich Mining Resource is located just west of U.S. Highway 85 and southwest of the city limits of Fort Lupton in Weld County, CO. The property is bound by the South Platte River to the west. Asphalt Specialties Co., Inc. (Asphalt Specialties) is both the permittee and operator of the proposed aggregate mining operation. Asphalt Specialties is proposing that the site be converted to a gravel pit to feed raw materials to their processing and sales point at the Chavers Mining Resource. The permit area of this operation will be 57.28 acres. The affected area will be 44.3 acres. All access to the site will be via a private easement across the agricultural parcel to the south and into the Asphalt Specialties Chavers Mining Resource (M-2015-030). Reclamation will convert the site to water storage ponds surrounded by rangeland. A portion of the ponds may be refilled based on market conditions for inert fill disposal. The proposed operation at the Marcovich Mining Resource will consist of mining sand and gravel, then transporting material to the Chavers Mining Resource. Processing of the extracted materials at the Chavers Mining Resource will include crushing, screening, washing, and the use of concrete and asphalt plants. 2. Explain the need for the proposed use: The site will provide additional gravel reserves to the Chavers Mining Resource to support development within weld County and the surrounding areas. No change of impact other than the duration of the Chavers operation is expected. 3. Describe the current and previous use of the land: Current land use is dry rangeland and a private residence. Future land use will be water storage, dry rangeland, and private residence. Historical use has been dry rangeland and a gravel pit. 4. Describe the proximity of the proposed use to residences: The closest residence to the gravel is owned by the lessor of the property. The next nearest residence is over a quarter mile away to the east across Highway 85. 5. Describe the surrounding land uses of the site and how the proposed use is compatible with them: Agricultural fields lie to the north and south of the site. Just beyond those fields are actively mined or reclaimed gravel pits. Highway 85 lies immediately to the east of the site. The South Platte River lies to the west of the site. Beyond the South Platte River lies additional fields and gravel pits. The site's planned use as a gravel resource and its future use of water storage and dry rangeland matches the South Platte River corridor use within the area. 6. Detail the hours and days of operation? i.e. Monday thru Friday; 8:00 a.m. to 5:00 p.m. Operating hours will match the Chavers Mining Resource (Resolution No. 2Q19RQ43). Those hours of operation for sand and gravel operations and concrete and asphalt batch plants are the hours of daylight, Monday through Saturday, except in the case of public or private emergency or to make necessary repairs to equipment. This restriction shall not apply to operation of administrative and executive offices or warm-up, repair and maintenance of facilities and/or equipment located on the property. 7. Describe the number of employees including full-time, part-time and contractors. If shift work is proposed, detail number of employees, schedule and duration of shifts: The Marcovich Resource is a satellite pit to the Chavers Resource to the south. Existing employees of the Chavers Resource will mine material and haul the material via a private haul road to the Chavers site. No additional employees are anticipated. 8. Describe the maximum number of users, patrons, members, buyers or other visitors that the site will accommodate at any one time: Customers will not access the Marcovich site to take delivery of construction materials. Those materials will be sold from the Chavers Mining Resource. Customers will also not access the Marcovich site for inert fill deliveries. Those materials will be delivered to the Chavers Mining Resource. 9. List the types and maximum numbers of animals to be on the site at any one time (for dairies, livestock confinement operations, kennels, etc.): None. 10. List the types and number of operating and processing equipment: Front end loaders, excavators, haul trucks, water trucks, and service trucks will access the site on a private road from the Chavers Resource. It is anticipated that the 1-2 front end loaders or excavators will feed up to 5 haul trucks. One water truck will be used for dust mitigation. One service truck will be used for servicing the equipment. Some or all this equipment may be stored onsite or at the Chavers site. 11. List the types, number and uses of the existing and proposed structures. None. 12. Describe the size of any stockpile, storage or waste areas. Topsoil stockpiles may exist along the Highway ROW fence. These will be temporary. Topsoil will be replaced in the reclamation areas as soon as possible. Location and size are shown on DRMS Map C-3. 13. Describe the method and time schedule of removal or disposal of debris, junk and other wastes associated with the proposed use. Mining operations at the Marcovich Mining Resource are expected to take approximately 7.3 years to complete, based on an annual average production of 700,000 tons. Actual production rates will fluctuate based on market conditions. An approximate mining timetable based on this production and the phased mining plan is shown in DRMS Permit Table D-1. A more complete description is included in Exhibit D of the DBMS Permit. Table D-1 Mining Timetable Description Time Required Construction of access road and slurry wall. 2 months Initial stripping of Northern Phase. 1 month Kline approved has and reached reclaim plans. its Reclamation maximum Northern Phase extents according occurs as in an area. to mining 3 years Initial stripping of Southern Phase. 1 month mine approved has and reached reclaim plans. its Southern Reclamation maximum Phase extents according occurs as in an area. to mining 3 years Total 7.3 years 14. Include a timetable showing the periods of time required for the construction of the operation: Please see Table D-1 above. 15. Describe the proposed and existing lot surface type and the square footage of each type (i.e. asphalt, gravel, landscaping, dirt, grass, buildings): None. No parking is planned for the Marcovich Resource. 16. How many parking spaces are proposed? Now many handicap -accessible parking spaces are proposed? None. No parking is planned for the Marcovich Resource. 17. Describe the existing and proposed fencing and screening for the site including all parking and outdoor storage areas: The site has existing fencing surrounding the property. The fences will remain in place as shown on the maps. The site lies completely below Highway 85 and would not benefit from screening due to the elevation difference. 18. Describe the existing and proposed landscaping for the site. The pre -mine, mining, and reclamation site topography can be seen on: • C-1 Access M a p • C-2 Baseline Map • C-3 Mining Map • C-4 Cross Sections • F-1 Reclamation Map The site is an agricultural parcel with a residence. The residence will remain unaffected by the mining. Mining will create a water storage reservoir and dry range land surrounding the reservoir. The cottonwood gallery will be left as a buffer to the South Platte River. 19. Describe reclamation procedures to be employed as stages of the operation are phased out or upon cessation of the Use by Special Review activity: DRMS Permit Exbibit E: Reclamation plan has been attached to this application. Reclamation activities, volumes, and stages are detailed in that exhibit. 20. Describe the proposed fire protection measures: The site will be stripped of vegetation within the affected area to reduce the potential for fire. Water trucks will be utilized for dust suppression at the site, and if necessary, can be used to suppress fire. Additionally, access will be maintained for emergency vehicles. 21. Explain how this proposal is consistent with the Weld County Comprehensive Plan per Chapter 22 of the Weld County Code: The Marcovich Mining Resource represents responsible mineral resource extraction. By utilizing the Chavers Resource as a processing and sale distribution point, the impacts to the surrounding areas will be minimized by maintaining the same traffic volumes and patterns which occur at the Chavers Resource. 22. Explain how this proposal is consistent with the intent of the zone district in which it is located: The intent of the Agricultural Zone is to maintain and promote agricultural and natural resource extraction without the interference of other incompatible land uses. The plan for the site anticipates responsible natural resource extraction. 23. Explain how this proposal will be compatible with future development of the surrounding area or adopted master plans of affected municipalities: The Marcovich Resource is located across Highway 85 from Fort Lupton, however, there is no public road access other than a non -conforming private driveway accessing Highway 85. The site's plan to utilize a private road to extract the resource removes all impacts to Highway 85 during mining and reclamation. Post reclamation the site will be utilized for water storage and dry rangeland grazing which will maintain the character of the area. 24. Explain how this proposal impacts the protection of the health, safety and welfare of the inhabitants of the neighborhood and the County: By utilizing the existing Chavers Mining Resources' processing area and access, impacts to the community will be mitigated. Mining within Marcovich Resource will be undertaken with care to limit impacts to the community. Roads and earth disturbing activities will be monitored for dust impacts and watered to mitigate those impacts. Noise impacts will be very limited. Mining will take place below the existing surface and Highway 85. As measured from the nearest residence to the east, noise generated is anticipated to by Highway 85 will greatly exceed the noise generated noise generated by the mining of the gravel. A noise study has been attached to this submittal. 25. Describe any irrigation features. If the proposed use is to be located in the A (Agricultural) Zone District, explain your efforts to conserve prime agricultural land in the locational decision for the proposed use: The only active irrigation structure on the site is a return ditch within the cottonwood gallery and will not be impacted by the affected area other than the required inlet and outlet structures for the reservoir. The return irrigation ditch is supplied by the field to the south of the site. 26. Explain how this proposal complies with Article V and Article XI of Chapter 23 if the proposal is located within any overlay Zoning District: --The-site is notlocated- within-an---o-verlay-d istrict. The site is in a floodplain. A floodplain permit has been submitted. 27. Detail known State or Federal permits required for your proposed use(s) and current status: 1. Colorado Division of Reclamation, Mining, and Safety Construction Material Regular Operation Permit — In Process 2. Colorado Air Pollution Control Division Fugitive Dust Permit and Air Pollution Emission Notice (APEN) — In Process 3. Water Quality Control Commission Discharge Permit — In Process 4.

General The Marcovich Mining Resource is within the floodplain and floodway of the South Platte River. The pond onsite is a remanent of a gravel pit that operated from 1960's until being captured by the river in the late 1970's. Central Colorado Water Conservancy District (CCWCD) installed augmentation wells east of Highway 85 that discharged into a ditch, flowed underneath the highway and into the pond in question. In 2009, CCWCD was ordered to cease and desist from pumping those wells. The ditch has remained abandoned since those orders. Billy Mihelich, PE, the district engineer authorized the ditch be removed by the mining. The mine's intent is to utilize the pond as a discharge point for dewatering activities to prevent potential for erosion at the discharge point. Sampling will occur prior to water entering the pond. Mining within the floodway will be conducted with no filling or stockpiling above the natural ground grade. Groundwater is located roughly five feet below the natural grade. All groundwater onsite is part of the South Platte River alluvial aquifer. Prior to mining, a slurry wall will be installed around the perimeter, as shown on Map C-3. These slurry walls will be for the development of water storage reservoirs following reclamation. Asphalt Specialties is committed to protecting the hydrological balance and water quality at the site. 2. Water Quality Protection The primary concerns surrounding water quality protection at the Marcovich Mining Resource site are the potential impacts to the surface and groundwater from sediment, hydraulic fluids, and diesel fuel. Sediment will be controlled through the use of stormwater retention within the disturbance area through the life of the mine. The site will be graded in a manner that maintains all surficial flows within the disturbed area, in turn containing all sediment and unwanted discharges from leaving the site. Hydraulic fluids and diesel fuels will be contained within vehicles that follow best practices of maintenance; these practices include regular inspections of vehicles, hydraulic lines, and any other potential spill sources. Diesel fuel or other oils will not be stored on -site. Any surface water discharges from the site will be sampled in accordance with the NPDES discharge permit. All discharge will be via the approved Outfall, the proposed location of which is shown on Map C-3. A dewatering sump will be utilized within the pit. The mine's intent is to utilize the pond as a discharge point for dewatering activities to prevent potential for erosion at the discharge point. Sampling will occur prior to water entering the pond.

CDPHE may issue different sampling requirements with the permit. 3. Floodplain The majority of the site is within the 100 -year floodplain and floodway as reported by the Federal Emergency Management Agency. These boundaries are shown in the Exhibit C and F maps. The minimum distance maintained from the South Platte River to excavation activities is 100 feet. Additionally, no stockpiling or filling above the natural grade will occur in the floodway. Overall, the downstream flood impacts should remain the same or be reduced from activity at the site as the removal of material results in more storage space for flood water below the existing grade. A no -rise certification has been provided to Weld County as part of its floodplain development permit. In accordance with the Mile High Flood Control District technical guidelines, inflow/outflow structures will be installed along the riverbank where mining reaches its closest point to the South Platte River. Details of these designs can be seen on Map G-1. In the event of flooding at the site, equipment from the active mining floor will be removed and the pit will be allowed to fill with water. The flooded pit will be pumped only after the flood has subsided. All fuel will be stored at least one foot above the base flood elevation and in sufficient secondary containment with 110% carrying capacity. 4. Wetlands The National Wetlands Inventory aerial -based mapping indicates the presence of wetlands within the permit area. They are however limited to a concrete lined ditch and a settling pond at the end of the ditch. An onsite inventory of potential wetlands will be undertaken before disturbing these areas. Exhibit C and F maps show the NWI mapped wetlands. Marcovich Gravel Pit September 2024 G-2 L Lewicki & Associates 5. Aquifers The only identified aquifer located at the site is the shallow alluvial aquifer of the South Platte River. The depth to this aquifer varies throughout the year but is typically five feet below surface. According to the U.S. Geological Survey's Ground Water Atlas of the United States, the underlying bedrock aquifer is the Laramie Fox Hills Aquifer of the Denver Basin system. The entirety of the Marcovich Mining Resource mining operation will take place in the overlaying alluvium above a shale/siltstone layer; the Laramie Fox Hills Aquifer will not be mined. 6. Surface Water The mining operation will impact surface water in the area through the stormwater runoff that enters the site. Map G-1 shows the drainage patterns and how they are affected throughout the life of the mine. The maps include information on the drainage basins currently, during mining, and post reclamation as well as the drainage directions throughout these stages. The primary concern for surface water protection at the site is preventing the discharge of sediment, oil, and/or hydraulic fluids from the operation areas. Oils and hydraulic fluids are stored on site following the standard best management practices. These practices include the use of secondary containment at fluid storage and transfer points, spill kits, and employee training regarding safe handling practices. Sediment is trapped onsite using controls and best management practices by directing and controlling surface water runoff that enters the disturbed areas. More information on sediment and surface water control is provided below. 6.1. Surface Water Handling One drainage basin collects all stormwater runoff on and around the Marcovich site. This is shown on the Drainage Map. Currently, the area has a series of dams to provide stock watering ponds. Those ponds will be removed prior to mining. 6.1.1. Mining During all phases of mining, surface water runoff will drain to the active pit or reclaimed reservoir. Water collected in the active mining pod will be allowed to evaporate or will be discharge via the approved CDPHE outfall once sediment has settled out. 6.1.2. Post Reclamation The drainage patterns during mining will be retained following reclamation of the site. Any surface water runoff will collect in the reclaimed reservoir. There is enough storage capacity above the anticipated reservoir level and the top of the shore to store the 100 -year storm events. More on those calculations are provided in section 6.2 below. 1 https://pubs.usgs.gov/ha/ha730/ch_c/ Marcovich Gravel Pit September 2024 G-3 L Lewicki & Associates 6.1.3. Flood Protection Mining will extend to within 200 feet from the South Platte River as shown on the Drainage Map. Due to this proximity to the river, measures will be taken to protect the riverbank from erosion during a flood event. An inflow and outflow structure will be constructed between the River and the mining pod once mining is within 300 feet of the river. These structures will allow for the safe exchange of flood waters between the pit and river which prevents erosion of the riverbank and pitside slope during flood events. These structures are of a design approved for use by the Mile High Flood District. Details of the inflow/outflow structure are shown on Map F-2. 6.2. Disturbed Area Runoff During all stages of mining, there is enough water storage capacity to contain the 5 -year and 100 -year 24 -hour storm events and prevent erosion from surface water discharge. The expected rainfall from these events at the Marcovich Site is provided in Table G-2 below. Table G-2. Area Storm Events (from NOAAZ) Event Probability Event Rainfall (inches) 5-YR 24 -HR 2.29 100-YR 24 -HR 4.64 The peak runoff was generated from these values for the three drainage basins during all stages of mining. Pre -mine, mining, and reclamation conditions are delineated on the Drainage Map. The discharge volumes from these storm events are calculated in Appendix G-1 at the end of this exhibit. Table G-3 summarizes the runoff volumes and storage volumes for each drainage. All drainage calculations were made using the Rational Method identified in the Mile High Flood Control District.

Groundwater Groundwater is located approximately five feet below the surface at the Marcovich site. This was determined from wells installed onsite. Table G-4 outlines all wells within 600' of the permit area. These well locations are also shown on Map C-2. Groundwater quality data was gathered in advance of mining. This data and discussion of it can be seen in the Groundwater Monitoring Plan in Appendix G-2. Table G-4.

Groundwater — Mining Prior to mining, a slurry wall will be installed around the perimeter of the pit to prevent groundwater flow into the mining area. Following slurry wall installation, the operator will mine out the pod by dewatering it via the approved CDPHE discharge point. Pumping to conduct this dewatering will take place during the initial mining and then pumping will cease. Stormwater runoff that is collected may be pumped out to protect local water rights, once sediment has settled. For this reason, the CDPHE discharge point will be maintained over the life of the mine. The pump will be located at least two feet below the active mining floor at the lowest point of the pit. It will be surrounded by a gravel filter. This configuration minimizes the risk of sediment being pumped out of the pit. The typical pit pump location can be seen on Map C-2. 7.2. Groundwater — Reclamation A permanent water storage reservoir will be left behind, as can be seen on Map F-1. There will be no groundwater consumptive use in reclamation. 7.3. Groundwater — Slurry Wall Impact The installation of a slurry wall within the alluvial aquifer of the South Platte River may create two potential impacts to the aquifer: the creation of local groundwater shadows or mounding that damage neighboring structures or property and the potential exacerbation of regional groundwater impacts. For these reasons, the applicant will submit a groundwater model prior to Marcovich Gravel Pit September 2024 G-5 L Lewicki & Associates installation of the slurry wall. If the determined by modelling, a French drain system will be installed to mitigate modelled impacts. 8. Water Related Permits The operator is applying for all necessary permits that have not already been acquired for water handling at the Marcovich Mining Resource. This includes a discharge permit with the Colorado Department of Public Health and Environment and a gravel well permit for initial dewatering of each pod with the Colorado Division of Water Resources. 9. Water Consumption and Source Water for dust control will be the primary consumptive use at the Marcovich Mining Resource site. Water will be purchased from a local source during operations for consumptive uses. No ongoing water consumptive use exists in reclamation, since the water storage pod is lined. This water will be sourced from a freshwater pond in the processing area. This pond will be covered by a gravel well permit. Table G-7 summarizes the estimated water consumption for the operation throughout the year. Marcovich Gravel Pit September 2024 G-6 L Lewicki & Associates Table G-5.

Dust levels will be maintained within the CDPHE Air Permit limits for the various facilities at the Marcovich Mining Resource. Dust generation is an inherent aspect of mining, so it can be expected that the Marcovich operation will create dust from various activities such as excavation, material handling, and hauling. Asphalt Specialties will work to reduce fugitive dust using various mitigation techniques such as spraying water andlor applying dust reducing chemicals. The use of dust controls will be increased during the summer when the dry, hot, and windy conditions exacerbate dust generation. All gravel access and internal haul roads require various dust mitigation techniques. Water spraying of roads on an as needed basis helps to reduce dust generation from vehicles. The roads may be chemically treated with magnesium chloride to help reduce dust generation for a longer term than water. This chemical binds the upper three to four inches of the ground to create a hard upper land that generates a minimal amount of dust. Controlling haul trucks and other vehicle's speed also helps to limit dust generation. Conveyor belts may also be used to transport material which are significantly less dust generating than haul trucks on travelling on gravel roads. Water will be applied directly from water trucks onto excavation areas, stockpiles, and any other disturbances to control dust. Stockpiles may require additional watering to ensure the material stays wet. Dust from the crushing and screening plant is controlled with water sprays at the entrance to the screen deck. The facility manager will decide when and where dust mitigation is needed during operations. The water used for dust control will be bought from a local source and trucked on site. 944 ACOUSTICS ran MARCOVICH GRAVEL PIT PRE -MINING NOISE ASSESSMENT To: Sydney Connor - Greg Lewicki and Associates From: Jeff Cerjan - Cerjan Acoustics CC: Shelley Morton - Cerjan Acoustics Subject: Pre -Mining Noise Assessment Date: February 14, 2025 Per your request, this technical memo provides the results of a pre -mining noise assessment for the proposed Marcovich Gravel Pit (Project) to be located in Weld County, Colorado outside the southern portion of Fort Lupton as indicated in Figure 1. The need for this analysis is to support the Project's request for a Special Use Permit. The Principal Consultant of Cerjan Acoustics, Jeff Cerjan, has been conducting mining and industrial noise analyses for over 22 years in Colorado, including Weld County. The following provides a description of the site and surrounding area, the applicable noise regulations, noise level prediction methodology, noise level results and assessment of compliance, and finally a conclusion statement summarizing the conditions assumed to achieve compliance.

The Project site is just west of US 85 about one -mile south of State Highway 52. The operating hours are planned for Monday through Saturday from 7:00 am to 7:00 pm (daytime). For this site, only mining will occur with the sand and gravel being hauled off site to the south for processing at an existing facility. Upon completion of mining, it will then be reclaimed with the pit becoming a water storage pond. The total life of the mine is anticipated to be approximately 7.5 years depending on demand. The immediate surrounding land use is agricultural with some other existing and reclaimed mining pits. The nearest residences are about 800 to 1,000 feet to the north and northeast. 1 f r r • • f t • • • Project Location . `�.1 .l 500 1,000 ft sip a5 Mllarcovich Project -- 0 Mining Boundary Permit Boundary Representative Residences Parcel Type Agricultural Exempt Residential 'vacant Land Figure 2 - Marcovich Gravel Pit and Surrounding Areas MARCOVICH GRAVEL PIT Pre -Mining Noise Assessment Page 12 944 ACOUSTICS ran APPLICABLE NOISE REGULATIONS The City of Fort Lupton does not have any noise regulations applicable to gravel pits. Weld County defines its noise limits in Chapter 14 - Health and Animals, Article IX - Noise, but states that any noise produced in the course of normal mining operations or oil and gas exploration, drilling, and production is exempt from these regulations (Section 14-9-60, Exceptions). Therefore, Weld County noise limits also do not apply to this Project. The State of Colorado defines noise limits in the Colorado Revised Statutes (CRS), Title 25, Article 12, Noise Abatement. CRS §25-12 noise limits are listed in Table 1, and depend on the time of day of operations, land use of adjacent properties, and type of operation. Table 1 — Colorado Revised Statutes §25-12 Noise Limits Zone Daytime(1)(2) (7:00 am - 7:00 pm) Nighttime ) (7:00 pm - 7:00 am) Residential 55 dBA 50 dBA Commercial 60 dBA 55 dBA Light Industrial 70 dBA 65 dBA Industrial 80 dBA 75 dBA (1) During the daytime, noise levels can be increased by 10 dBA for 15 minutes in any one -hour period (2) Noise level limit decreases by 5 dBA for intermittent, shrill type sounds Time of Day The mine will only operate from 7:00 am to 7:00 pm, which is considered daytime hours as defined by CRS §25-12 (7:00 am to 7:00 pm is daytime). Thus, only daytime limits apply. Land Use While Table 1 states "zone," the applicable limits are really defined by the actual land "use" as the CRS "zone" generally does not align with local zoning. As the Project property itself is considered Industrial, the Project should limit noise to 80 dBA at a location 25 feet outside the Project property boundary. Additionally, there are surrounding lands that are Agricultural in both "zone" and "use". The Project is committed to meeting the Residential noise limits at all existing residential structures. Type of Operation The type of operation affects these limits in three ways. First, during the daytime, the noise level limit can be increased by 10 dBA for 15 minutes in any one -hour period. This is applicable to intermittent sources of mining noise, such as an excavator or haul truck moving close to a property boundary for a brief period of time. Second, noise level limits are reduced by 5 dBA for impulsive or shrill type sounds, which would apply to "tonal" backup alarms, but not "broadband" back-up alarms which are not impulsive or shrill. Third, construction activities (i.e., erecting berms, slurry walls, or structures) are subject to the Industrial zone limits per CRS §25-12 regardless if the adjacent property has lower limits due to its land use. MARCOVICH GRAVEL PIT Page 13 Pre -Mining Noise Assessment 944 ACOUSTICS ran Summary of the Applicable Noise Limits Overall, the Project needs to be at or below the Industrial daytime limit of 80 dBA at a location 25 feet outside its Project boundary. At the same time, the Project should also remain at or below the Residential daytime limit of 55 dBA at residential areas and structures. As noted above, the noise level limit can be increased by 10 dBA for 15 minutes in any one -hour daytime period but can also be reduced by 5 dBA if the noise is impulsive or tonal (i.e.: tonal backup alarms). This is consistent with prior mining projects in weld County and other counties in Colorado. MARCOVICH GRAVEL PIT Page 14 Pre -Mining Noise Assessment 944 ACOUSTICS ran NOISE LEVEL PREDICTION METHODOLOGY N oise levels were predicted per International Organization for Standardization (ISO) 9613-2:1996 - Acoustics - Attenuation of Sound During Propagation Outdoors using the SoundPLAN v9.1 software package. ISO 9613-2:1996 predicts noise levels assuming slight downwind conditions (wind blowing from source to receptor) with an accepted accuracy of ±3 dB out to 1,000 meters. The following provides descriptions of the input data used to create each SoundPLAN model. Atmospheric Conditions The air temperature, relative humidity, and atmospheric pressure were set to conditions of 10°C, 70%, and 1 atmosphere, respectively. These values represent a low amount of atmospheric absorption of sound available in the ISO 9613-2:1996 method, and result in higher levels of sound reaching the receptors. Terrain and Ground Effect The terrain in the area was modeled by importing a digital elevation model (1/3 arc -sec) from the N nited States Geological Survey (USGS) website (https://apps.nationalmap.govidownloader/#/). The acoustical effect of the ground can be modeled using ground factors from 1.0 (completely absorptive) to 0.0 (completely reflective). A ground factor of 0.3 was used for the mining areas and 0.5 for all other off -site areas. The reflection order was set to 2 (two) reflections. The settings are felt to be reasonable and yet still conservative for these predictions. N oise Barriers There are no noise barriers included in the model other than the existing terrain itself. It is anticipated that overburden will be stockpiled along the eastern portion of the site, but this was not included as a barrier. Receptors In the SoundPLAN model, receptors (noise prediction points) were located at the five representative existing residences, including the nearest, that are all in Residential zones. These prediction locations were reviewed using Google Earth. The receptor heights were set to five feet above the ground, as is common practice. N oise Level Contours While noise receptors are predictions at a discrete point like a residence, noise level contours predict the location of a specific noise level. This provides a graphical view of the predicted levels. For this model, noise level contours were predicted at a height of five feet above the ground using a reflection order of 2 (two) to be consistent with the noise receptor point predictions. N oise Source Levels The sound power levels for each piece of equipment are provided in Table 2. These levels were determined from measurements of similar equipment in Colorado and were compared to other published levels. Note that the "sound power level" is independent of the distance from the source, ground type, etc., and represents all the sound energy comprised into one point. All noise sources were set to ten feet above the ground. For the phases of removing the overburden and the actual mining, the predicted levels are for when the equipment is at the existing ground level. For the reclamation phase, the two haul trucks were placed in the pit with the bulldozer at ground level outside the pit.

These predicted levels are intended to be "worst -case" in which all equipment is operating at its loudest constant level at the existing ground level. All predictions per ISO 9613- 2:1996 are generally considered accurate within ±3 dBA out to 3,300 feet (1,000 meters). The daytime noise level limit for the property boundary is 80 dBA and 55 dBA for the residential structures. For each mining phase, noise levels were predicted at the five nearest representative residences as well as 25 feet outside the property boundary. The following provides the predicted noise level results due to the noise from the overburden removal and mining phase, reclamation phase, backup alarms, and haul route. Overburden Removal and Mining Noise The Project anticipates that the noise from the removal of the overburden and they actual mining will use the same or similar equipment consisting of one excavator and two haul trucks (offroad). For both phases, the worst -case noise will occur when the equipment is at the existing grade in full operation. A summary of these results is provided in Table 3 along with an assessment of compliance with the noise regulations. Noise level contours were also predicted and overlaid onto an aerial of the site as shown in Figure 3, which is focused on the residences. As shown, the 55 dBA noise level contour (Residential daytime limit) remains away from any residential structure and the 80 dBA noise level contour (industrial daytime limit) remains well within the Project boundary. Reclamation Noise The Project anticipates that the noise from the reclamation would require the use of one bulldozer and two haul trucks (offroad). The worst -case noise will occur when the bulldozer is at the existing grade outside the pit and the two haul trucks operating in within the pit. A summary of these results is provided in Table 3 along with an assessment of compliance with the noise regulations. Noise level contours were also predicted and overlaid onto an aerial of the site as shown in Figure 3 which is focused on the residences. As shown, the 55 dBA noise level contour (Residential daytime limit) remains away from any residential structure and the 80 dBA noise level contour (industrial daytime limit) remains well within the Project boundary.

To minimize complaints, many operators have replaced these tonal alarms with ambient -controlled broadband backup alarms. These alarms constantly measure the background noise level and produce a backup warning sound that is significantly less than a fixed volume tonal alarm. Furthermore, the broadband aspect of these alarms replaces the tonal "beep" with white noise (i.e.: static noise) that is less noticeable at a distance. A measurement of an ambient -controlled broadband backup alarm on a previous project resulted in a sound pressure level of 55 dBA at 240 feet away when indirect line of sight. The nearest edge of the mining area (approximate location) is no closer than 800 feet to the nearest residence, thus the backup alarm noise should remain below 55 dBA and be in compliance with the applicable noise regulations. Noise Level Assessment of Haul Route A haul route is proposed to run along the west side of US 85 for about 1 mile to carry haul trucks from the mining site to the existing processing facility. The nearest residence to this route is about 1,000 feet to the east on the other side of US 85. A haul truck pass was acoustically modeled along the proposed haul route and was estimated to be below 50 dBA which is below the 55 dBA limit. In addition, based on CDOT's Online Transportation Information System website (Station ID 103691), US 85 was counted carrying over 2,000 vehicles per hour during the daytime on average in 2023 with 10% of those being a combination of medium and heavy trucks traveling at 65 mph. Thus, adding an estimated 12 haul truck roundtrips per hour at slower speeds is not expected to be noticeable by the nearest residence or any other more distant residence. MARCOVICH GRAVEL PIT Page 19 Pre -Mining Noise Assessment 944 ACOUSTICS ran CONCLUSIONS A pre -mining noise assessment was conducted for the proposed Marcovich Gravel Pit which was required by the City of Fort Lupton, Colorado. While Fort Lupton and Weld County both do not have noise regulations applicable to gravel pits, the State of Colorado does as per CRS, Title 25, Article 12, Noise Abatement (CRS X25-12). A total of four noise assessments were conducted which included one for the overburden removal and mining phases, one for the reclamation phase, one for the noise due to backup alarms, and one for the haul route to the south. As previously shown, all are expected to be in compliance with the limits within CRS X25-12. With that said, there are some associated assumptions and/or conditions. The following lists these assumptions and/or conditions. 1) The Noise Source Power Levels listed in Table 2, while somewhat conservative, should not be exceeded for each piece of equipment. 2) Backup alarms on all construction equipment should be broadband and ambient controlled and not exceed the sound power level in Table 2. 3) While no noise mitigation barriers are required for compliance, there will be opportunities to use the overburn and topsoil stockpiles as a noise berm if found necessary.

The original Chavers' site began operation in August 2616. This update is being prepared to respond to an increase in the area being mined. The Chavers site consisted of approximately 74.25 acres. An additional 57.3 acres is being added to the site. The additional acreage is located approximately 0.75 miles north of the original Chavers site. The attached Figure 1 depicts the location of the expanded mining operation site (Marcovich Pit Site) with respect to the existing Chavers mining operation site. An access road will be built that connects the Marcovich Pit site to the existing Chavers site. This will ensure that all of the haul traffic from the Marcovich Pit site will use Access A at Weld County Road 8 to access US 85. Once approval is given for the Marcovich Pit, reining operations will cease temporarily at the Chavers Pit until mining at the Marcovich Pit is complete. Processing and sales activity will continue at the Chavers Pit site, with material mowed from the Marcovich Pit to the Chavers Pit site on a private, internal roadway that has been built. It is anticipated that the Marcovich Pit will cease operations in 2033. By the year 2038, it is anticipated that raining operations at the Chavers Pit will also cease operations. Development of the Marcovich Pit site as an aggregate mine will only add traffic between it and the Chavers Pit for mining and will not affect the traffic volumes coming into or out of the Chavers Pit site. Background The dune 21, 2015 traffic study included a single access along Weld County Road 8. This access is located approximately 525 feet west of US 85. At full build out, the site was expected to generate 194 daily vehicle -trips with 19 vehicle -trips in the AM peak -hour and 19 vehicle -trips in the PM peak -hour. Of the 194 vehicle -trips, approximately 90 percent were expected to be IIIPage haul trucks. The directional distribution assumed that 100 percent of the haul trucks would access the site from the south. All of the trade movements at the two intersections along Weld County Road 8 (Access A and US 8g) were expected to operate at an acceptable Level of Service (LOS "D" or better) during the Ails and PM peak -hours through the Year 2024. A turning movement analysis was performed for northbound US 88 to westbound Weld County Road 8. This analysis showed that the existing asphalt is sufficient to handle the haul traffic. Existing Condition The lane geometry at the site access (Access A) and Weld County Road 8 has not changed. However, the lane geometry for the eastbound and westbound approaches at Weld County Road 8 and US 85 now have separate through/left-turn and right -turn lanes. There is enough asphalt to allow for separate right -turn lanes for both approaches. The presence of northbound and southbound acceleration lanes on US 88 permits the right -turning vehicles to make a free right -turn onto US 85. The aftached Figure 2 depicts the traffic control and lane geometry that will be used in this update. Figure 2 also depicts the storage lengths for the dght-turn and [eft - turn deceleration lanes on US 85. New peals --hour traffic counts were taken at the two intersections along Weld County Road 8 at Access A and US 88. The afkached Figure 8 depicts the new peak -hour turning movement -traffic counts. Appendix A contains the raw traffic counts used in the preparation of this update. Trip Generation Because the shavers mining operation as well as the Eumco concrete batch plant operation are already taking place, there is no need for developing estimates of site -generated traffic. Asphalt Specialties has indicated that they do not foresee an increase in the vehicular activity{ to and from the site. Trip Distribution The June 21, 2015 traffic impact analysis report indicated that all of the traffic to and from the C havers site would come from the south. The new traffic counts supports this assumption. Future Traffic Volumes Asphalt Specialties estimates that it will cease operation of the Chavers site in the Year 2088. A growth factor of 1.29 was applied to the pear --hour through traffic volumes on US 88 as well as the traffic entering US 88 from weld county Road 8. A growth factor of 1.14 was applied to the through traffic on Weld County Road 8 at Access A as well as the peak -hour traffic c leaving U 88 onto Weld County Road 8. The attached Figure 4 depicts the Year 2088 peak -hour traffic volumes. Estimated Traffic Impacts The methodology used to estimate the traffic impacts of the existing shavers site as well as the 1111 arcovi ch Fit site is presented in the nationally accepted 2010 Highway Capacity Manual, 2[Page published by the Transportation Research Board of the National Academy of Sciences. The concept of Level of Service (LOS) is used as a blasts for computing combinations of roadway operating conditions. By definition, six different Levels of Service are used (A, B, C, D, E3 and F) with "A" being a relatively free -flow condition and "E" representing the capacity of a given intersection or traffic movement. The AM and PM peak -hours have been analyzed since they are the times of maximum impacts upon the street network. A total of two intersections along Weld County Road 8 (Access A and US 85) are being analyzed in this report. Table 1 summarizes the results of the AM and PM peak -hour Level of Service analyses for the Chavers Traffic Study Update report (actual computer analysis printouts are included in Appendix B).

Eastbound Approach Southbound Approach A (9.3) A (8.6) A (9.3) A (8.6) Weld County Road 8 & Access All of the traffic movements at this unsignalized intersection are expected to operate at an excellent Level of Service (LOS "A") during the AM and PM peak -hours through the Year 2038. US 85 & Weld County Road 8 Two traffic movements are currently experiencing problems in the AM and PM peak -hours. They are the eastbound and westbound throughileft-turn traffic movements. Both of these traffic movements are operating at a poor Level of Service (LOS "F"). The average vehicle delay is in excess of 100 seconds per vehicle. The other traffic movements are currently operating at an acceptable Level of Service (LOS "D" or better) during the AM and PM peak -hours. By the Year 2038, there is no change in the performance of this unsignalized intersection, ti I L I. I l w-1'l',m 3[Page Mitigation Measures To mitigate the poor performance of the eastbound and westbound through and right -turn traffic movements at US 85 and weld county Road 8, this intersection should be converted to a three- quarter intersection by eliminating the through and left turn traffic movements. This change will only be impacting a small number of vehicles. Table 2 depicts the results of these mitigation measures.

Northbound Left -Turn Southbound Left Ti urn B (10.8 c (17.3) _B. (12.8) U (27.4) The need for this mitigation measure is not due to the traffic entering and/or leaving the shavers mineral extraction site. These mitigation measures are due to the traffic wanting either to go north onto US 85 from Weld County Road 8 or continue east or west along weld county Road 8. As a result of these mitigation measures: traffic corning from the west will have to go south along Weld County Road 23 to Weld County Road 6 and then east along Weld County Road 8 to US 85. Traffic coring from the east will have to go south along Weld County Road 27 to Weld County Road 8 to US 85. The intersection of US 85 and Weld County Road 8 is controlled by a traffic signal which will make it easier to either make the left -turn traffic movement onto U 88 or continue east or west along Weld County Road 8. The small number of vehicles being diverted to Weld County Road 8 should not result in a significant change in the performance of the signalized intersection of US 85 and weld county Road 8. Conclusion The existing roadway network will be able to handle the traffic from the mineral extraction operation at the existing Ch avers site and the proposed M arcovich Pit site. 4]Page This completes my update to the chavers Traffic Study.

Danube Circle Aurora, Colorado 80015 Phone: (720) 231-1947 E -Mail: druble.jr@corncast.net June 21, 2015 Mr. Rob Laird Asphalt Specialties 19100 Dallas Street Henderson, CO 80840 Re: Chavers Mining Resource Development Fort Lupton, Colorado Dear Mr. Laird: As requested, I have completed the traffic impact analysis of the proposed shavers Dining Resource development. This letter report presents my findings and recommendations concerning the traffic impacts of the proposed Chavers Mining Resource development. This report represents an update to the March 27, 2008 traffic impact analysis report prepared by LSC Transportation Consultants. Summary and Conclusions Based on the analyses presented herein, the following summarizes my findings relative to the traffic impacts of the proposed shavers Dining Resource development. 1. The site will be served by a single access from the north onto Weld County Road 8, directly opposite an abandoned access on the south. This access is located approximately 525 feet to the west of US 85. 2. At full build out, the proposed resource development is expected to generate approximately 194 vehicle -trips (97 vehicles entering and 97 vehicles exiting) during an average weekday. Of these, 19 vehicles trips would occur during the morning pear -hour (14 vehicles entering and 5 vehicle exiting), while 19 vehicles trips would occur during the evening peak -hour (5 vehicles entering and 14 vehicles exiting). Of the 194 vehicle trips that are expected to be generated by the site, 174 vehicles will be haul trucks and the ether 29 vehicles will be light truck/automobiles. Out of the total 19 vehicles that are expected to be generated during the morning peak -hour, 10 vehicles will be haul trucks (five entering and five leaving the site). The other nine vehicles will be light trucks/automobiles (nine vehicles entering and no vehicles leaving the site). Out of the total 19 vehicles that are expected to be generated during the evening peak -hour, 10 vehicles will be haul trucks (five entering and five leaving the site). The other nine Page 1 of 7 vehicles will be light trucks/automobiles (no vehicles entering and nine vehicles leaving the site). This information was provided by asphalt Specialties, Inc. 3. The directional distribution of site -generated traffic is expected to be such that 100 percent of the traffic generated from the proposed development will access the site from the south using US 85 and ''Weld County Road 8. 4. Two intersections were analyzed in this report, CAS 851e1d County Road 8 and Weld County Road 8/Access A. The Years 2010 and 2024 were analyzed for this report. All traffic movements at the two unsignalized intersections are expected to operate at an acceptable Level of Service (LOS "D" or better) for both the ,morning and evening peak - hours through the Year 2024. 5. The existing lane geometry and traffic control devices will be adequate for handling the background and site -generated traffic through the Year 2024. 5. The traffic impacts from the proposed Chavers Mining Resource development are minor and can be handled by the existing roadway network. Site Location and Proposed Access The site is currently located in Weld County, Colorado at the northwest corner of US 85 and Weld County Road 8. Fort Lupton is in the process of annexing the site. Access to the site will be provided via a single access along Weld County Road 8 on the north side. This access is located approximately 525 feet west of US 85. Figure 1, enclosed, depicts the location of the proposed development with respect to the surrounding land uses and roadway network. Existing Traffic Condition US 85 is currently a four -lane roadway with north/south continuity through Weld County. The intersection with Weld County Road 8 is an unsignalized intersection with stop control on Weld County (Road 8. Weld County Road 8 is a two-lane, east/west county road with continuity between East County Line Road on the west and Weld County Road 45 on the east. This roadway is paved along the frontage for the proposed shavers Mining Resource development site. The pavement width is approximately 24 feet with a two -foot unpaved shoulder. Figure 2 shows traffic control and lane geometry at the two intersections analyzed in this report. Figure 3 depicts the traffic counts taken for this report. Turning movement traffic counts were taken at US 85/Weld County Road 8. These traffic counts were taken by Counter Measures, Inc. on .dune g, 2015. The raw traffic counts are attached to this report. Large vehicles turning movement counts were taken at the same intersection. In addition, a daily vehicle classification count was taken can IBS 85 south of weld County Road 8. This count is also shown in Figure 3. Page 2 of 7 Estimated Traffic Generation The Institute of Transportation Engineers (ITE) does not provide any traffic generation estimates for a resource extraction development therefore, ,asphalt Specialties, Inc. provided this information. At full build out, the proposed resource development is expected to generate approximately 194 vehicle -trips (97 vehicles entering and 97 vehicles exciting) during an average weekday. Of these, 19 vehicles trips would occur during the morning peak -hour (14 vehicles entering and 5 vehicle exiting), while 19 vehicles trips would occur during the evening peak -hour (5 vehicles entering and 10 vehicles exiting) . Of the 194 vehicle trips that are expected to be generated by the site, 174 vehicles will be haul trucks and the other 20 vehicles will be light truck/automobiles. Out of the total 19 vehicles that are expected to be generated during the morning peak -hour, 10 vehicles will be haul trucks (five entering and five leaving the site). The other nine vehicles will be light trucks/automobiles (nine vehicles entering and no vehicles leaving the situ. Out of the total 19 vehicles that expected to be generated during the evening peak -hour, 10 vehicles will be haul trucks (five entering and five leaving the site) . The other nine vehicles will be light trucks/automobiles (no vehicles entering and nine vehicles leaving the site). Estimated Future Peak -four Traffic Volumes opening day, the Year 2010, and the Year 2024 are being analyzed in this report. Figure 4 depicts the estimated traffic on opening day while Figure 5 depicts the estimated traffic for the Year 2024. These volumes were generated by comparing the traffic counts taken in the Year 2008 to the counts taken in 2015. In some cases the 2015 count is less than the 2008 count, but this negative growth rate was not used. Based on this comparison, no grovvth was applied to Weld County Road 8, west of US 85; a one percent annual growth rate was applied to US 85; and an eight percent annual growth rate was applied to Weld county Road 8, east of US 85, Trip Distribution The directional distribution of site -generated traffic onto adjacent roadways, which provide access to and from the proposed shavers Mining resource development, is one of the most important components in the assessment of the proposed development's traffic impacts. The major factor which influences the traffic distribution assumptions is final destination of the aggregate being rained at this site, both are located south of the site. Considering the combined effects of these factors, it is felt that 100 percent of the traffic generated from the proposed development will access the site from the south using US 85 and Weld County Road 8. Figure 8 depicts the distribution of site -generated that is felt to be appropriate for this, report. Page 3 of 7 Trip Assignment and Traffic Volumes Figure 7 illustrates the assignment of site -generated peak -hour traffic on the adjacent street system. The assignment of site -generated traffic is based upon the trip distribution percentages shown in Figure 6 and the vehicle -trip generation in Table 1. The Year 2016 total peak -hour traffic volumes at US 85ANeld County Road 8 and Weld County Road 8/Access A are illustrated in Figure 8 while the Year 2024 total pear -hour traffic volumes are illustrated in Figure 9. The Year 2016 peak -hour traffic volumes were derived by adding the site - generated traffic from Figure 7 to the Year 2010 background peak -hour traffic volumes in Figure 4. The Year 2024 total peak -hour traffic volumes at US 85/Weld County Road 8 are illustrated in Figure 9. These volumes were derived by adding the site -generated traffic from Figure 7 to the Year 2024 background peak -hour traffic volumes in Figure 5. Estimated Traffic Impacts During the morning and evening peakshours, the primary traffic impacts for the proposed resource development will be at the intersections of US 85NVeld county Road 8 and Weld County Road 8/Access A. The traffic controls and lane geometry assumed in the analyses are shown in Figure 2. The methodology used is that presented in the nationally accepted 2010 Highway Capacity Manual, published by the Transportation Research Beard of the National Academy of Sciences. The concept of Level of Service (LOS) is used as a basis for computing combinations of roadway operating conditions. By definition, six different Levels of Service are used (A, B, C, D, E, and F) with "A" being a relatively free -flow condition and "F" representing the capacity of a given intersection or traffic movement. The morning and evening peak -hours have been analyzed since they are the times of maximum impacts upon the street network. Table 2, enclosed, summarizes the results of the morning and evening pear -hour Level of Service analyses for the proposed Dhavers Mining Resource development (actual computer analysis printouts are also enclosed)_ 0 US 85NVeld County Road 8; This unsignal zed intersection has stop control on the Weld County Road 8. All but three of the traffic movements at this unsignalized intersection are expected to operate at an acceptable Level of Service (LOS "CAP" or better) during both the morning and 'evening peak -hours through the Year 2024. The eastbound and westbound approaches are expected to experience problems in the Year 2024during the evening peak -hour for the background and total traffic condition. This is primarily due to traffic desiring to make either a left -turn or go through the intersection having to wait for a gap in northbound and southbound traffic to complete their traffic movement. There are no mitigation measures that could be implemented to eliminate the poor level of service. Page 4 of 7 • Feld County Road 8/Access A: This unsignalized intersection has stop control on Access A. The southbound approach at this intersection is expected to operate at an excellent Level of Service during the morning and evening peak -hours through the Year 2024. Based on the above Level of Service analysis, the existing roadway system will be able to handle the background and site -generated traffic through the Year 2024. Average Daily Traffic Impacts Figure 10 shows the average daily impacts due to site -generated traffic including the daily number of heavy vehicles generated by the proposed Chavers Alining Resource development. The average daily impacts are minimal, indicating that by Year 20.24, it is estimated that the site -generated traffic will account for less than one percent of the daily traffic on USX 5. The impact to Weld County Road 8 is expected to be more pronounced. Site -generated traffic will result in a doubling of the traffic on Weld County Road 8. This increase in daily traffic along Weld County Road 8 will not result in this roadway requiring any widening. Truck Impacts on Pavement Condition The destructive effect of repeated wheel loads is the major factor which contributes to the deterioration of roadway pavements. Since both the magnitude of the load and the number of repetitions are important, a provision is made in pavement design procedures to allow for the effects of the number and weight of all axle loads expected during the design period. The Colorado Department of Transportation (CDOT) uses pavement design procedures which convert traffic data to 18 Kip equivalent single -axle load applications (18K ESAL). Eighteen Kip or 18,000 lbs. is the maximum legal load allowed on a single axle. CDOT uses the following load equivalency factors for flexible pavement design: 1. Passenger vehicle: 0.003 2. Single -unit trucks: 0.249 3. Combination trucks: 1.087 The latter category includes most of the dump trucks and tractor trailer combinations that would be hauling materials from the proposed Chavers Alining Resource development. Eighteen Kip ESALs have been calculated for the proposed Chavers Alining Resource development on Weld County Road 8 using the CDOT load equivalency factors and assumptions regarding the breakdown of traffic into the various vehicle classifications. Based on these assumptions, the proposed development will generate about 212,850 ESALs over the life of the site. As a result, over the life of the site, the traffic generated by the proposed Chavers Alining Resource development account for approximately 03.8 percent of the total number of ESALs on Weld County Road 8 west of US 85. The results of the ESAL analyses are contained in Table 3. Page 5 of 7 Auxiliary Lane Requirements US 85 is under the jurisdiction of the Colorado Department of Transportation and the State Highway Access Code is used todetermine the auxiliary lane requirements for state highways. The portion of US 85 that is near Feld County Road 8 has an access category of EX (Expressway). At the intersection of US 85 and Weld County Road 8, the fallowing auxiliary traffic lanes are currently available: • northbound left -turn deceleration lane (897.2 feet) • southbound right -turn deceleration lane • southbound left -turn deceleration lane • northbound right -turn deceleration lane • eastbound right -turn acceleration lane (1,171.5 feet) • westbound right -turn acceleration lane According to the Mate Highway Access Code, a deceleration lane needs to be 800 feet and an acceleration lane needs to be 1,880 feet. These lengths are based on a posted speed limit of 55 mph. Based on field measurements, the northbound deceleration lane is adequate. The eastbound right -turn acceleration lane is about 190 feet short of meeting the Mate Highway Access Code standards. The recent overlay project for US 85 did not bring this acceleration lane up to standard. AutoTurn Analysis An analysis was performed at the intersection of US 85 and Weld County Load 8 to .make sure the haul trucks will be able to safely enter US 85 from Weld County Road 8. Figure 11 depicts the results of this analysis. As can be seen in Figure 11, some additional asphalt will need to be added to the existing asphalt surface which is depicted in Figure 11. No final determination was made as to whether or not the additional asphalt can be accomplished within CDOT's existing right-of-way, but it appears that it can based on recent surveys made by the Town of Fort Lupton. I trust that my findings and recommendations will assist in the planning for the proposed Chavers Mining Resource development. Please call rye if 1 can be of further assistance.

Name: Greg Geras Company: Asphalt Specialties Co. Inc. Title: Land & Resource Manager Signature: Date: Marcovich Mining Resource December 2024 2 L Lewicki & Associates Introduction This Stormwater Management Plan is prepared to mitigate potential impacts to Waters of the U .S. (South Platte River) resulting from the operations at the Marcovich Mining Resource by Asphalt Specialties Co. Inc. in Weld County, Colorado. Water quality, drainage, monitoring, and pollution control are addressed in this Plan. Adherence to this plan will allow Asphalt S pecialties Co. Inc. to contain potential pollutants on the site and have a plan of action for minimizing the risk of contaminating surface waters. Discharge is to the South Platte River and this certification is written for the standards of the South Platte River. This Plan includes stormwater and process water. The Marcovich Mining Resource will be mined in one cell. During the mining, the active pit will serve as a settling pond, capturing stormwater and process water. The pit will have a dewatering pump and discharge pipes. 1. Key Elements of this Plan • Process Water (water used for periodic dewatering, product washing, and runoff from gravel stockpiles) shall be contained within the site perimeter and routed to the settling ponds and mine pits on the site. Water is then pumped and discharged at the permitted discharge points for the site (See SWMP Map). • All disturbed areas will drain into the active pod or the be contained within the processing area. See the SWMP Map for flow directions from particular portions of the site • Stormwater from rainfall or snowmelt will inadvertently mix with process water or become process water if it flows across the disturbed area and shall be contained within the site and routed to the active pits or contained within the processing and stockpile area. These areas are a sufficient size to capture storm events and to allow solids to settle to the bottom. These areas will be monitored for sediment buildup and will be cleaned out as required to maintain settling volume. • Any discharge of Process Water to surface waters or to groundwater will be regulated through the Water Quality Control Division for discharges associated with sand and gravel production operations for stormwater and process water. Asphalt Specialties Co. Inc. obtained a Discharge Permit to allow discharge of Process Water from the pit. • Any discharge of Process Water from the site shall be sampled and tested for flow, pH, Total Dissolved Solids, oil and grease (visual), Oil and Grease, Electrical Conductivity, Total flow, and Total Suspended Solids. The person sampling discharge shall evaluate the flow rate and look for the presence of any oils (oily sheen). Marcovich Mining Resource December 2024 3 L Lewicki & Associates • The only acceptable methods of managing on site stormwater runoff are to contain it for Use in Operations, for Infiltration into the ground, for Evaporation into the air, or Discharge to the River. • Sediment is classified by the State as a potential pollutant that can negatively affect the quality of stormwater discharges. Loose sediment from gravel washing and trucks, etc. will be contained on site completely and not be allowed to be carried off site by stormwater. Erosion control methods such as revegetation or graveling of the processing and stockpile area will be implemented on the site to control sediment migration during stormwater runoff events. • The best method of managing site runoff water quality is to remove and properly dispose of any site contaminants that could be transported by stormwater runoff. All activities that could produce pollutants will be restricted to specific contained areas or have built-in secondary containment. See the SWMP Map for the locations. Drips, leaks and spills will be cleaned up regularly. More detail on these items is provided later in this Plan. • All fuel tanks, petroleum product storage and other chemicals will be regulated under the SPCC plan for the site.

Site Description The Marcovich Mining Resource is a sand and gravel processing operation located approximately 1.0 mile south of the center of Fort Lupton, CO along the west side of state highway CO -85. The site is bordered by the South Platte River to the west, rangeland to the south & north, and the highway to the east. The Marcovich site is 57.3 acres in size, most of which will be active during the mine life. Sand and gravel is extracted and taken to the Chaver's Pit to the South. The site is immediately west of the South Platte River. The water table is shallow. Prior to mining, a slurry wall will be installed to prevent groundwater inundation. Initial mining will require groundwater dewatering to empty the pod. Mining will be conducted such that the active mining area will behave as the site sump for disturbance area runoff. The active pit will have a mine dewatering pump and discharge pipe which will discharge storm and process water to the South Platte River. Once surface water is collected within the mining pit, it will be collected in the pit floor perimeter ditches and be routed to the pit dewatering pumps. The pit dewatering pumps will then pump into existing drainage swales in undisturbed ground onsite to return to the South Platte River. The pit pumps will always be located at least two feet below the active mining floor to ensure clean water pumping. All structures are shown on the SWMP Map. Stockpiles are located on the eastern portion of the site outside of the pit and floodway. The majority of the site is within the Federal Emergency Management Administration (FEMA) Floodplain Zone A (100-YR event). The western portion of the site is within the floodway. Groundwater is roughly 5 feet below the natural grade and is the alluvial aquifer of the South Platte River. All the disturbed area water and storm runoff water is contained within the active pit or within the processing area with the use of a stormwater berm. Sediment free water is pumped to the South Platte River via outfalls. The SWMP Map shows the outfall locations. Marcovich Mining Resource December 2024 7 L Lewicki & Associates 2. Standard Industrial Classification (SIC) Codes SIC CODE INDUSTRY DESCRIPTION 1442 Processing of Sand & Gravel 3. Description of Operations Asphalt Specialties Co. Inc. will conduct mining and gravel processing operations under a Division of Mining, Reclamation and Safety (DRMS) Permit. The DRMS permit will be released following full site reclamation. Asphalt Specialties Co. Inc. is permitted for the following uses on the Marcovich Mining Resource: • Dewatering from the pit during mining; • Mining of sand and gravel Brief descriptions of these operations are provided below: 3.1. Mining of the Pit Mining will require dewatering. Following the construction of a slurry wall around the pit, the pit will be pumped dry to facilitate mining. All discharge from this pumping will be via the approved discharge outfall(s). Mining within the pit will consist of excavation of sand and gravel and transport above grade to the processing area via trucks. 3.2. Sand and Gravel Processing No processing will take place at this site. 3.3. Fuel Storage A portable fuel tank may be set up in the mining area to supply equipment onsite. It will have full secondary containment. All equipment onsite will have onboard diesel tanks in full secondary containment. Full secondary containment has 110`)/0 of the volume of the tank that is in it. 3.4. Chemical Storage No chemicals will be stored on site. 3.5, Shop activities There is no shop onsite. Marcovich Mining Resource December 2024 8 L Lewicki & Associates 4. Basin Descriptions for Areas of Industrial Activity 4.1. Drainage Basins to Site Discharge Point One discharge point exists onsite for mine dewatering. The pit will drain internally during mining. The discharge points are the destination for the majority of the site's drainage area. No offsite areas drain to the site. Surface flow directions are shown on the SWMP Map. 4.2. Drainage Basin to South Platte River As shown on the SWMP Plan Map, the entire disturbed area of the site will ultimately drain to the South Platte River via the discharge points. This entire area is below isolation berms, containment ditches, or reclamation slopes. 4.3. Off -site Sources There are none for this site. 4.4. On -site Stormwater and Process Water Runoff The disturbed areas of the site are handled as follows: • The majority of the disturbed area drains to the discharge points of the active mining area. The discharge points are preceded by mining pits for sediment trapping. Sediment is allowed to settle out in the pits prior to water being discharged. A combined stormwater/process water discharge permit is in place for discharge from the mining pits. Stormwater volume was determined using the calculations below as described in the "Procedures for Determining Peak Flows in Colorado," that includes and supplements Technical Release No. 55 "Urban Hydrology for Small Watersheds." Prior to discharge, sediment will be controlled by allowing for settling in the pit. Marcovich Mining Resource December 2024 9 L Lewicki & Associates 4.5. Stormwater Calculations During mining, the Marcovich site will have drainage properties as outlined on the SWMP Map. The 100-YR runoff event volume for each basin is listed below. These quantities have been calculated following the NRCS TR-55 Curve Number Runoff Method. Hyd.

There is sufficient storage capacity within the pit to contain stormwater runoff and prevent sediment laden discharge during mining. 4.6. Groundwater Groundwater is dewatered from the active mining area via Outfall 001-A. 5. Summary of Existing Discharge Sampling Data The Marcovich Mining Resource discharges daily during mining due to dewatering of the pit. Records of sampling are kept on site and are available upon request by an inspector. The sample form is included in Appendix A. Marcovich Mining Resource December 2024 10 L Lewicki & Associates 6. Description of Sampling Points The Marcovich Mining Resource has one discharge point for the site. These can be found on the SWMP Map. The discharge point is permitted with the Colorado Department of Public Health and Environment's (CDPHE) sand and gravel construction discharge permit. Parameters to be sampled are listed below in the following table. Effluent Parameter Flow, MGD Total Flow Oil and Grease, visual Oil and Grease, mg/I pH, s.u. Total Suspended Solids, mg/I Total Dissolved Solids, mg/I Electrical Conductivity 7. Monitoring Procedures Measurement Frequency Monthly Monthly Twice / Month Contingent Twice / Month Twice / Month Quarterly Quarterly Sample Type In -situ Calculated Visual Grab Grab Grab Grab Grab Samples will be collected in a manner that represents the discharge of all outfalls. Samples will be made with a clean, clear glass, or plastic container and examined in a well -lit area for: color, odor, clarity, floating solids, settled solids, suspended solids, foam, oil sheen, and other obvious indicators of pollution. Records of the results of sampling will be maintained with the SWMP located on site. All monitoring is conducted under the supervision of the SWMP Administrator. Yearly reports are sent to CDPHE-WQCD that detail the site's progress in implementing strategies that will aid in meeting compliance with final selenium limitations. Marcovich Mining Resource December 2024 11 L Lewicki & Associates Stormwater Management Controls 1. SWMP Administrator The SWMP Administrator is responsible for daily SWMP administration at the site. This designated person is listed at the beginning of this document along with their contact information. 2. Risk Identification and Assessment It is anticipated that no stormwater discharges will occur for any stormwater events prior to being allowed to settle in the pit. A summary of estimated risks if a discharge were to occur is presented below: 2.1. Potential for Discharge from Basin: Pollutant Oil and Grease Low Total Dissolved Solids Low Total Suspended Solids Low pH (Outside Range 6.5 to 9.0) Low 2.2. Identification of Potential Pollutant Sources 2.2.1. Disturbed and Stored Soils All topsoil stockpiles will be maintained at an equal to or shallower than 2H:1 V slope. To prevent erosion, all non -aggregate stockpiles will be seeded within three -months of establishment. Herbicides are applied annually to control weed growth on all materials stockpiles. All stockpiled overburden and topsoil will ultimately be used in the reclamation process. 2.2.2. Vehicle Tracking of Sediment As the site has truck traffic hauling materials out of the site, these activities have some potential to discharge sediment laden water but the BMP's outlined in this Plan make a sediment laden discharge a remote possibility. The BMP most responsible for reduction of this potential is the fact that access roads within the site drain the sediment settling ponds and the processing and stockpile area, in addition to all access roads, will have a gravel floor. Marcovich Mining Resource December 2024 12 L Lewicki & Associates 2.2.3. Management of Contaminated Soils The site has no contaminated soils. If a spill occurs, any contaminated soils will be isolated from the area draining to the sediment settling ponds that have no discharge. These materials will be treated or hauled off site in conjunction with the procedures of the SPCC Plan. 2.2.4. Loading and Unloading Operations Screened gravels are located on site in the stockpile area. All of these areas are contained by isolation berms and the settling pond, so the potential for significant pollution from these sources is very low. 2.2.5. Outdoor Storage Activities (Storage of Chemicals) No chemicals are stored onsite. 2.2.6„ Vehicle and Equipment Maintenance and Fueling There is no used oil or chemical tanks on -site. Portable equipment will have contained fuel tanks with secondary containment. Minor maintenance will be performed on the portal equipment on an `as -needed' basis. Without BMP's there is a significant potential to discharge pollutant laden water but the BMP's outlined in this Plan make pollutant laden discharges a remote possibility from this source. The primary BMP's are a) the secondary containment of the tanks, b) containment of the areas on site where the fueling and maintenance occurs, and c) the inspection/training/maintenance procedures outlined in the SPCC Plan. 2.2.7. Significant Dust or Particle Generating Processes Mining takes place in a 29.1 acre active area of the site. Without BMP's there is a significant potential to discharge sediment laden water but the BMP's outlines in this Plan make polluted laden discharges a remote possibility from this source. The primary BMP is as needed water spraying for road dust suppression. The inherently wet nature of the material at the Marcovich Mining Resource should reduce the possibility of generating dust pollution. Additionally, the gravels at the Marcovich Site contain few fines, thus limiting the possibility of pollution due to the liberation of these fines. 2.2.8. Routine Maintenance Activities involving Fertilizers, Pesticides, Detergents, Fuels, Solvents, oils, etc. No fuels, chemicals, fertilizers, etc. will be stored onsite. Limited routine maintenance activities on the portable plants will take place onsite. 2.2.9. On site Waste Management Practices All onsite waste will be disposed in facilities operated by the local municipality. Marcovich Mining Resource December 2024 13 L Lewicki & Associates 2.2.10. Non -Industrial Waste Sources such as Worker Trash and Portable Toilets Portable toilets are used on site and are regularly serviced by a licensed contractor when workers are present. Worker trash is disposed of in the waste bins that are also taken to the approved landfill by the local waste management company. Without BMP's there is a slight potential to discharge pollutant laden water but the BMP's outlined in this Plan make pollutant laden discharges a remote possibility from this source. The primary BMP's are the factory supplied waste trash bins, and porta potties, with the proper disposal of the trash and the porta potty waste. 2.2.11. Building Roofs There are no buildings onsite. 2.2.12. Other Areas or Procedures Where Potential Spills Can Occur Other than the tanks identified in this Plan and the SPCC Plan, there are no other tanks or other sources that could result in a spill other than a rupture of hydraulic lines and diesel tanks associated with the mobile equipment on site, a loader and dozer. Without BMP's there is a reasonable potential to discharge pollutant laden water but the BMP's outlined in this Plan make polluted laden discharges a remote possibility from this source. The primary BMP's are a) the fact that the quantities on the mobile equipment are small, less than 120 gallons of diesel fuel and 60 gallons of oil, and b) the SPCC Plan requires spill kits that will be used to mop up any spill with the mobile equipment. Marcovich Mining Resource December 2024 14 L Lewicki & Associates 3. Preventative Maintenance The following are the inspection and maintenance practices that will be implemented to control stormwater runoff quality: • The SWMP Administrator will be responsible for inspections, maintenance and oversight of any required repair operations. SWMP inspections will occur at least four -times per year and records of these inspections will be kept on file on site with the SWMP Plan. • Ground slopes will be minimized to limit erosion and slow down flow during a stormwater event. • Final backfilled disturbed areas and stockpiles will be reseeded when practical to minimize erosion and sediment transport. • Inspect all tanks for leaks, proper dispensing equipment and adequate secondary containment in conjunction with the SPCC Plan. • Inspect all Isolation berms on site for disruption, erosion, or any other fault that requires maintenance. 4. Good Housekeeping The following good housekeeping practices will be employed at the site: • Substances stored on site will be stored in a neat, orderly manner in their appropriate containers. • open containers of non -hazardous materials shall be covered to prevent mixing with stormwater. • The Safety Coordinator is responsible for day-to-day site operations and directing spill prevention, cleanup, and reporting. See Marcovich Mining Resource SPCC Plan. • No waste oil will be stored onsite. • If drip pans are used, they will be cleaned on a regular basis and not allowed to fill with stormwater, and the contents disposed in a landfill approved to handle such waste. • No hazardous materials will be stored onsite. 5. Stormwater Control Measures This Stormwater Management Plan was developed to improve the water quality of stormwater runoff. The Stormwater Control Measures (SCMs) are intended to prevent the discharge of sediment laden stormwater from this site.

Inc., through the Stormwater Administrator, will train and educate current and new employees on appropriate stormwater management, spill response, good housekeeping and materials storage practices. Best management practice training programs should also be conducted regarding improving the water quality of stormwater runoff. 7. Testing for Non-stormwater Discharges The only non-stormwater discharges expected at this site are stormwater and process water. Therefore, no testing for illicit connections or other non-stormwater discharges is proposed. 8. Amendments This SWMP plan must be amended whenever there is a change in facility design, construction, operation, or maintenance that materially affects Asphalt Specialties Co. Inc. potential for discharge of pollutants (sediment, oils, etc.) into or upon waters of the United States. Such amendments must be implemented not later than six months after the change occurs. Any amendments to the SWMP plan will be developed by a Qualified Person. Marcovich Mining Resource December 2024 16 Lewicki & Associates Final Site Stabilization As required in the Colorado Division of Reclamation, Mining and Safety permit, the site is to be reclaimed to rangeland and groundwater ponds. Comprehensive Inspection The SWMP Administrator will conduct regular inspections of the site for stormwater management controls, spill control, maintenance, and cleanup. Inspections during at least the spring and fall of each year shall be conducted and the records of such inspections shall be maintained in files at the site together with the SWMP Plan. Inspections shall incorporate a complete review of all BMP's outlined in this plan and will report on any BMP's that are not functioning and/or require maintenance. Any discharges that are out of compliance with the discharge permit shall also be reported with corrective actions outlined. Record Keeping and Internal Reporting Procedure Incidents such as spills or other discharges, together with other relevant information describing the quality/quantity of stormwater, will be included in records maintained at the site. Inspection records and maintenance records will be maintained at the site. At least four comprehensive Stormwater Management Plan inspections (spring, summer, fall, and winter) will be conducted each year for annual reporting to CDPHE. These reports shall include the date of the inspection, findings and actions taken, and submitted with the Annual Stormwater Report due February 15 each year. Consistency with other Plans The SPCC Plan will be consistent with the SWMP Plan and will be available on site. A general discharge permit has been obtained from CDPHE. If other permits affecting stormwater are required of the site in the future, the SWMP will be modified to ensure consistency. These plans will also maintain consistency with the County and DRMS permits. Allowable Non-stormwater Discharges There is one process water and commingled storm water discharge point for this operation. That discharge is for dewatering of the pit and is covered under the Discharge Permit for the Marcovich Mining Resource.

Marcovich Mining Resource December 2024 24 L Lewicki & Associates EXHIBIT E RECLAMATION PLAN 1. General Reclamation Plan The total affected area to be reclaimed under this permit is 44.2 acres out of the 57.28 -acre permit area. Reclamation of the Marcovich Mining Resource will convert the site to a final land use of a water storage pond surrounded by rangeland. Reclamation will occur concurrently with mining. Final reclamation will be completed after mining has finished. The pre -mine land use is predominantly agriculture with one residence. Surroundings land uses include agriculture, open space, and mining. Pursuant to Rule 6.4.5.2(b), the applicant evaluated the post -mine land use in regard to adopted state and local land use plans for this area and adjacent land uses. The proposed post -mine land use of water storage ponds and rangeland is compatible with the general agricultural character of the area. Table E-1 below summarizes the anticipated final land uses within the affected area upon completion of reclamation. The distribution of rangeland and water storage pond may vary based on the market demand for inert backfill storage. Table E-1 Reclamation Areas Description Area (Acres) Rangeland 12.1 Water Storage Pond 26.7 Access Roads/Easements 2.63 Disturbed Area Total 41.4 Undisturbed Area 15.8 Total Affected Area 5 7.2 8 Reclamation will occur concurrently as mining progresses. No more than 1,000 feet of highwall will be unreclaimed at a time. Mining slopes will be backfilled and graded to a maximum 3H:1 V slope. The slopes will then be compacted for stabilization and to prevent erosion. All portable facilities and equipment will be removed from the area. All berms will be flattened. The slurry wall will remain during and after reclamation. The pond slopes and any other surrounding disturbances will be topsoiled and seeded for revegetation. Topsoil will be replaced in a two -foot layer to restore the current soil profile. Revegetation will be completed using a native seed mix recommended by the Natural Resource Conservation Service. Revegetation efforts will be monitored following reclamation. The pit will be used for freshwater storage after it has been fully reclaimed and revegetated. There will be more than enough material stockpiled from on -site materials to fulfill reclamation needs as the groundwater lake takes up the majority of the reclamation area. Table E-2 shows the volumes of topsoil and overburden required for reclamation and the material volumes that will be stripped and stockpiled. As shown, there is an excess of topsoil that is stripped versus what is required for reclamation. The stripped overburden does not meet the amount required for backfilling the pits. However, there will be an excess of topsoil and sand that will be more Marcovich Gravel Pit November 2024 E-1 L Lewicki & Associates than enough to meet these requirements. These calculations were made assuming that the site has a uniform one foot of topsoil and 2.5 feet of overburden across all areas. Sand volumes were not calculated as detailed information on their location and thickness were not obtained. No sand volume is assumed for the reclamation volume balance calculations, however, sand is very likely to be encountered. Any sand encountered will either be sold or used to augment the overburden for backfill. Topsoil will be replaced in an average two -foot layer across all non -pond disturbances, while overburden and other excess material will be used to backfill the pit slopes from 1.5H:1 V to 3H:1 V. Table E-2 Reclamation Volumes Material Available on Site Requirements for Reclamation Reclamation Area Area (acres) Topsoil Stripped (CY) Overburden Stripped (CY) Topsoil Required (CY) Overburden Backfill Required (CY) Mining Area & Surroundings 32.2 51,870 129,680 30,300 109,278 Excess material will be used for backfilling slopes. Sand that may be encountered will be used for backfilling or will be sold. Asphalt Specialties will keep the minimum amount of material (topsoil, overburden, and potentially sand) required for reclamation throughout the entire mine life. Based on market demand, a portion or all of the area within the slurry wall may be backfilled. If the site is completely or partially backfilled the amount of area reclaimed as dry rangeland will increase. The operator will ensure that material is clean and uncontaminated. They will utilize the same forms as the Chavers Resource because the Chavers resource will act as the processing and sales point for the Marcovich site. 2. Alternative Reclamation Plan The site may alternatively be reclaimed to entirely rangeland following a Technical Revision. The pit will be backfilled entirely with excess material from both on and off site. Material will be graded and compacted prior to topsoiling, ripping, and seeding for revegetation. All other components of reclamation will remain the same as the primary reclamation plan, except for the removal of the water storage use. Pit walls will be backfilled to 3H:1 V after mining is completed in an area. See Map F-3 for details on the alternative reclamation plan. The approximate volumes needed for reclamation are as follows. It is assumed that all pit walls have been backfilled to 3H:1V prior to the total backfilling of the pit. The volume to backfill the walls to their final reclaimed slopes is shown in Table E-2. Marcovich Gravel Pit November 2024 E-2 L Lewicki & Associates Table E-3 Material Available on Site Requirements for Reclamation Reclamation Area Area (acres) Topsoil Stripped (CY) Overburden Stripped (CY) Topsoil Required (CY) Pit Backfill Required (CY) Mining Area & Surroundings 32.2 51,870 3. Topsoil Replacement 129,680 51,870 1,194,650 An average of one foot of topsoil will be stripped and stockpiled prior to mining. After backfilling and grading has been completed during reclamation, topsoil will be replaced at 0.5 to 1.5 feet, at an average depth of one foot in a manner that is similar to the pre -mine soil profile. Topsoil will only be placed on the pond slopes and other surrounding disturbances. Topsoil will not be replaced on the pond floors. Replaced topsoil will be directly placed by loaders and haul trucks. All topsoiled areas will be disced to aid in root penetration. 4. Haul Roads and Access All internal haul roads will remain following reclamation to support the future land use. 5. Reclamation Timetable and Sequence The sequence and timing of reclamation can be seen in Table E-4 below. The reclamation schedule is dependent on the rate of mining and fluctuating market demands. The operator will reclaim the site concurrently with the progression of mining to limit the total disturbance. Table E-4 Reclamation Timetable Description Time Required Develop and mine Northern Phase 3 years Develop and mine Southern Phase 3 years Backfill, disturbances topsoil, and revegetate remaining 1 year Vegetation monitoring 2 years Total 9 years Marcovich Gravel Pit November 2024 E-3 L Lewicki & Associates 6. Revegetation Plans Seed will be placed in all areas to be vegetated following grading, topsoiling, and discing of the soil. All disturbances that are retopsoiled will be seeded with a Rangeland Seed Mix. The Weld County recommended mix to be used is as follows: 6.1. Rangeland Seed Mix Species Sand Bluestem Sand Lovegrass Indian Ricegrass Prairie Sandreed Green Needlegrass Little Bluestem Yellow Indiangrass Switchgrass rass Sand Dropseed Total Pounds of pure live seed per acre (drilled) 1.0 2.5 3.0 0.75 1.5 0.75 0.5 1.5 0.5 12.0 Broadcast seeding will be done at double the drill rate. Mulch will be placed at roughly 4000 pounds per acre. 7. Post Reclamation Site Drainage The site will drain internally following reclamation. All water that enters the site will drain to the water storage pond in the center of the site. Refer to map G-1 for the post reclamation drainage of the site. 8. Revegetation Success Criteria Revegetation will be deemed adequate when erosion is controlled, the vegetation cover matches neighboring wildlife habitat areas, and when it is considered satisfactory according to Division standards. This will be monitored for a minimum of two years following the completion of reclamation. 9. Monitoring Reclamation Success Measures will be employed for the control of any noxious weed species. The objective of this weed management plan is to control undesirable plants on the Marcovich property. Plants identified through the Colorado Noxious Weed Act (C.R.S 35-5.5) and the Weld County Noxious Weed List as undesirable and designated for management within the county will be removed. Marcovich Gravel Pit November 2024 E-4 L Lewicki & Associates Any weeds identified as List A species will be eradicated. Other lower listed plants identified as noxious weeds will be managed by control measures. A Weed Control Plan will be utilized as follows: 1) Each April, a weed survey will be taken of the permit area. 2) If any patches or plants have been identified, they will be sprayed by backpack sprayer or 4 -wheeler using chemicals approved for use by the weed control staff of Weld County. 3) After reclamation, weed surveys and spraying will continue until the perennial cover and production of the site have met DRMS requirements and bond release has been obtained. The Division and Weld County staff will be consulted regarding any weed infestation areas and any control measures prior to their initiation. The plan does not contemplate total weed removal on the property. Rather, the goal is to prevent the spread of weeds into uninfected areas as is the primary goal of the Weld County Weed Management Plan. Each year during the mining operation, the permit area will be monitored closely, through which the operator may determine if any additional weeds have grown. If any new species of weeds are found, Weld County and the Division will be consulted in order to formulate the best plan for the new infestation. 9.1.
