Dewatering trenches and pumps will be used throughout the entire mining process; no water will be impounded on site. The dewatering trench as well as small settling ponds will allow sediment to settle before the water is discharged into the Poudre River. The entrance and exit will be located in the southeast portion of the site, off O Street. The entrance will consist of a 150 feet long, 24 feet wide paved road, including a turn radius to assist semi -trucks turning left and heading east on O street. The site will be mined and reclaimed in order to create a stable and sustainable environment. The proposed final land uses for the site are water storage and residential. The overall site reclamation, focusing on topsoil placement and revegetation with drought -tolerant native or adaptive plant species, will commence at the end of all mining due to the single mining phase. Since mining, agriculture, water storage and residential are the common land uses in this area, the proposed reclamation will be appropriate in this location. Hall -Irwin Corporation, who will construct the slurry wall, retained Brierley Associates to complete geotechnical investigation and design for the slurry wall. The subsurface investigation consisted of geotechnical borings and test pits in the fall of 2018. Laboratory testing from the field investigation reviled eolian deposits overlying alluvial deposits followed by sedimentary bedrock. Bedrock was encountered in each boring ranging from approximately 33 to 44 feet below ground surface. Within the alluvial aquifer, groundwater was encountered during drilling at depths ranging from approximately 8 feet to 19.6 feet below ground surface. The site will be mined at a 3H:1 V slope from the start, so the need for backfill to re -slope the perimeter will be extremely minimal. Final grading, the placement of topsoil and seeding will be the focus of reclamation efforts post -mining. Topsoil placement will consist of 6-12 inches on all disturbed areas, including the stockpile locations, ditch crossing, proposed shoreline, and armored inlet channel. Table 1 below suggests the native grass seed mix from the USDA-NRCS to be used on this site'. The guide is for a Native Grass Drill; if seed is planted via broadcast methods, then all pounds of live seed will be doubled. Mulch and a cover crop were optional suggestions per the USDA guidelines. TABLE 1. SUGGESTED VAT/1'T. GRASS SEED .111.1' BASED OV SITE LOCATION.

Based on the guidance, it was determined that a single armored side channel spillway would be sufficient to meet the inlet and outlet structure requirements. Using a side channel spillway, the slurry wall and pit slopes will remain protected. Note the spillway will be constructed to not decrease the carrying capacity of the Storms Lake Drainage. The spillway will be primarily vegetated but will transition to Type M riprap, a concrete cutoff wall and finally a spillway grade concrete rundown along the 3H:1V V mined slope to approximately 5 feet below the high water mark; here the rundown will transition back to Type M riprap to the bottom of the mined area. This specified design utilizes one of the slope protection methods (concrete spillway) suggested by UDFCD, but equivalent spillway protection may also be used (grouted boulders, soil cement, concrete pavers). This design can be reviewed in more detail on the reclamation plan map. 2. Consistency with the Weld County Comprehensive Plan The application proposal is quite consistent with Weld County's Comprehensive Plan, specifically industrial development. The pit will ultimately supply aggregate to numerous users in Weld County. Aggregate is a valuable resource with economic benefits. Following the removal of the aggregate, the site will be restored to another, but equally valuable, beneficial use of water storage. 3. Consistency with District Intent The property is within the Agricultural (A) district. Section 23-3-10 of the Weld County Code describes the intent of the A (Agricultural) Zone District as to include uses by special review which may have a more intense or greater impact. As described above, aggregate is another valuable resource found within Weld County. 4. Efforts to Conserve Agricultural Land As discussed in question 3, the property is, in fact, zoned as A or Agricultural. The applicant has made a diligent effort to conserve productive agricultural land by locating the use on a small parcel surrounded by those of similar use. The area is not necessarily preferable for growing crops and has not been used as such for years. The proposed use will not negatively impact nearby agricultural ditches, wells or water rights. 5. Protection of Health, Safety, and Welfare Bucklen Services Company is committed to protecting the health, safety and welfare of the inhabitants of the neighborhood and County, particularly because Bucklen Services will be working within its own community. The applicant will comply will all State and local permits. The final reclamation of the site will provide additional water storage area to the county which will increase the general welfare of future residents in the area and the county as a whole. 6. Compatibility with Surrounding Land Uses Currently, most properties to the east, south and west all have Weld County USR permits for mining. The area and others surrounding the parcel are currently zoned as agricultural. Therefore, gravel mining of this parcel is compatible with surrounding land uses. 7. Existing Land Use Currently, the land is used as agriculture for grazing and industrial storage. There are also numerous underground utilities within the site.

Site Details a. The site will have two full-time employees. There are no visitors or buyers expected on site. b. The hours of operation will consist of Monday through Friday, 8:00am to 5:00pm for approximately 50 weeks out of a given year for approximately 10 years. c. There will be no animals on this site. d. The types of vehicles accessing this site will include passenger cars/picks, semi- trucks/trailers; each will make approximately 17 round trips per day. Other mining specific equipment include scrapers, wheel loaders, dozers, excavator and water trucks. Note these pieces of equipment will not be accessing the site daily but rather remain on site as needed. e. The property is within the Windsor Severance Fire Protection District. f. Not applicable, no water will be used on the property for the purposes of mining. Water needs for the employees will be brought onsite as needed. g. Currently there is no sewage disposal system on site. There is no proposed sewage disposal system; Portable toilets will be placed on site as needed. h. The only storage proposed onsite is for topsoil and overburden from the mined area. i. The stockpile area is in the southwest corner of the site. The stockpiles will not be located on top of any utility lines and it will be located outside of Western Area Power Administration's 50 feet easement for their above ground lines. j. Proposed landscaping on the site includes creating grassy hills near the facility entrance. These will aid in dust control and reduce noises from the industrial mining activities in the gravel pit below. There will be fencing to deter any curious children from entering the mine location off O Street. k. Construction onsite will begin as soon as permits are finalized, hopefully by October 2019. The landscaping portion will commence with construction and will take approximately a month to complete under ideal conditions. The site will be mined for approximately 10 years. After this, reclamation and final landscaping will begin. I. All reclamation will follow the Colorado Division of Reclamation Mining and Safety standards. For this site that includes 3H:1 V side slopes, final grading and seeding and an off - channel spill way. These items are described in more detail above. m. To enable dry mining throughout the site, dewatering trenches will be constructed around the perimeter of the pit. An 8 -inch pump will be installed to pump the water out of the pit and into settling ponds in between the pit and Storms Lake Drainage. These settling basins will be relatively small, approximately 30' wide by 30' long. Clean water from the settling ponds will then be collected and taken off site to ultimately be discharged in the Cache La Poudre River. Also note, this will be done in accordance with a Colorado Department of Public Health and Environment water quality permit, Colorado Discharge Permitting System (CDPS), which will be obtained prior to mining. The outfall pipe will also include a water meter to measure the quantity of water that is pumped out of the pit. n. Not applicable — no debris, junk or other wastes will be associated with this site. The topsoil will be kept onsite until reclamation and then used. Overburden will be used or transferred to Bucklen's site for sale or other use. Any other items used for mining the site will be removed after mining is complete. o. Weld County is an industrious and growing county. The material mined from this proposed pit is necessary for the expansion of the county in several ways. The activities of mining benefit the economy by creating jobs for men and women who reside in Weld County. The aggregate will be used in many ways by Bucklen Services Company's customers, but primary uses include road construction, home construction, concrete materials, and landscaping products. The ability to provide cost effective materials like these are vital to a www.applegategroup.com Denver • Glenwood Springs • Hotchkiss (303) 452-6611 RE: Weld County USR Application Questionnaire Tollgate Pit July 22, 2019 Page 5of6 growing community, and aggregate prices over the past 10 years have outpaced inflation, demonstrating that, in Weld County, the demand for such products is growing faster than the supply. Thus, additional gravel mines like the Tollgate Pit would be an asset to the area. Finally, the water storage facility proposed as the final reclaimed use will help the county make beneficial use of one of our most valuable resources for decades after the mining process is complete. 9. USR Area Location The Use by Special Review area is not located in a geologic hazard or Weld County Airport overlay district area. Half of the site is located with the John Law Floodplain. Measures for reclamation have accounted for this and the Use by Special Review includes a Flood Hazard Development Permit. Oil and Gas Agreements There are multiple oil and gas facilities within the property boundaries. As a part of the Division of Reclamation Mining and Safety permit, any owner of a structure within 200 feet of the property had to be notified and had the opportunity to sign a structure agreement. Of the 22 Owners who were sent notifications and structure agreements, the Owners listed below followed through with the agreements. The signed agreements of the two oil and gas companies are also attached for reference. • Atmos energy • Century Link (no oil and gas) • DCP • Judy Firestien (adjacent property owner, no oil and gas) • Western Area Power Administration (overhead electric transmission lines, no oil and gas) Noise Report Article IX of the Weld County, Colorado Charter and Code describes the maximum permissible noise levels for an industrial Area or Construction Activities to be 80 dB(A) from 7:00 a.m. to 9:00 p.m. and 75 dB(A) from 9:00 p.m. to 7:00 a.m. Table 2 below describes the machine and the peak noise level produced by this specific model or type. Most of the peak noise levels for the different types of machines are above the 80 dB(A) maximum allowance but all mining and noise activities will be located further away than 50 ft from the property boundary, which is where the peak noise level is measured based on the Federal Highway Administration. Section 14-9-50 of the Weld County Municipal Code defines measurement and classification of noise and describes measuring noise at least 25 feet from the source of the noise. For mitigation, dirt berms will be placed in areas deemed most sustainable or effected by high noise levels (i.e. residential property). As mining continues and the pit descends, the amount of noise disturbance will decrease to surround properties. There will be no constant stationary noise from items like pumps (after initial dewatering), crushing, or screening. Since all construction equipment is mobile, no one area adjacent to the mine shall be persistently noisy. TABLE 2.

SECTION LINE + SECTION CORNER II PROPERTY/PERMIT e i, TOPSOIL/OVERBURDEN - - STOCKPILES BOUNDARY EXHIB MINING PLAN IT D The land within the existing mining operation is owned by Orrlando LLC (Orrlando). Orrlando has entered into a lease with the Bucklen Services Company for the purpose of mining aggregate onsite. The proposed permit boundary of approximately 60 acres is displayed in Exhibit B Vicinity Map, with mining activities anticipated to disturb approximately 25 acres of the site. The remaining unmined acres will be used as sites for overburden and topsoil stockpiles, offsets from existing structures, property lines and waterways and internal access. Geologic mapping by Hershey and Schneider (1972) indicates that the parcel to be mined is on one alluvial deposit of the Valley Fill alluvium north of the Cache La Poudre River. Specifically, the site is a higher terrace deposit which contains arkosic gravel and sand with some loosely cemented sand and gravel. Boring data, included in Exhibit S, indicates that bedrock is located at approximately 40 feet below the ground surface. The primary commodity to be mined is aggregate. The secondary commodity would be clean fill dirt, but it has not been determined if this will be sold. Aggregate will be sold off of Bucklen Services Company's sale yard. Methods of Mining Access to the site will be located in the southeast portion of the site, off O Street. The entrance will consist of a 150 feet long, 24 feet wide paved road. This road will also include a turn radius that will assist semi -trucks turning left and heading east bound on O Street. At any one time, the active mining area will include the entire mine boundary, encompassing 25 acres. The area will be worked on in a single phase, but will have three layers. The entire mine boundary will have topsoil stripped off, followed by the overburden, and finishing with the extraction of gravel to a depth of approximately 12 feet. This process will begin in the southeast and move towards the north on the site. Topsoil will be moved by scraper or excavator and dump truck to the southwest corner of the property where it will be stockpiled (see Exhibit C Mining Plan Map). A bridge or culvert crossing over the Strom Lake Drainage Ditch will be necessary to get heavy equipment across to the stockpile location; the crossing will be constructed so as not to impede flow in the drainage ditch. There is approximately 40,000 CY of topsoil on site. Approximately 2,000 CY will be stockpiled a day, until all topsoil has been moved to stockpile area. The 40,000 CY of stocked topsoil will remain on site and will be maintained in place through equally distributed mechanical compaction; no chemicals will be used. If necessary, stockpiles will be seeded to protect against wind and water erosion and be incorporated into a weed control program. Overburden will be moved by scraper or excavator and dumb trucks to the stockpile area, southwest of the mining area, as well. No dragline will be used in this process. Onsite, there is approximately, 302,000 to 444,000 CY of overburden, which will be stockpiled at a rate of 2,000 CY a day. Most of this stockpile will remain on -hand to be used for reclamation activities, while a small portion may be sold off. Tollgate Pit DRMS 112 Permit Application Page D-1 There is no drilling, blasting or explosives planned to be used on this site. The mining operation does not propose to generate hazardous materials or waste. No material will be processed on site; this pit will only export material. Once the raw material is extracted, it will be taken to Bucklen Services's yard in either belly, end, or side dump trucks using a wheel loader or excavator directly from the virgin bank. It is estimated that an average of 1,000 tons will be transported daily, resulting in approximately 250,000 tons annually. A large majority of the material will be crushed, screened and washed at Bucklen Services's yard. The pit will be mined dry, requiring dewatering trenches and pumps throughout the entire process of mining; no water will be impounded on site. Prior to mining, a dewatering trench will be constructed around the perimeter of the site to collect groundwater that drains from deposit and surrounding alluvium. The trench will allow for sediment to settle before the water is discharged to the Storm Lake Drainage Ditch. Please refer to Exhibit G — Water Information for details regarding dewatering plans. No exported material is planned to be stockpiled in the pit or throughout the site. Due to this, there will be no finished product located within this site. Prior to the start of mining or shortly after mining has begun, a slurry wall will be constructed around the mine boundary. This will aid in decreasing dewatering demands, as well as, future reclamation plans of water storage. All surface water within the mine areas will rain internally. There will not be any uncontrolled releases of surface water and sediment from mining areas. Stormwater collected in the open mine will be managed in accordance with a Colorado Discharge Permit System (CDPS) discharge permit for this operation. Sediment generated from localized stormwater runoff and surface drainage will be managed according to the Stormwater Management Plan (SWMP) that will be developed in conjunction with the CDPS permit. The SWMP will be designed to prevent the contact and transport of potential contaminants by stormwater flows. In order to minimize any air pollution, industry best practices will be followed. This includes but is not limited to minimizing unnecessary material movement and watering roads where vehicles create dusty conditions. Mining Schedule Bucklen Services Company proposes to move approximately 250,000 tons of material annually. At this rate, it is expected that the site will be mined and reclaimed in 10 years, however, the rate of mining and life of the mine is completely dependent upon demand and market conditions. Mining Phases Overview The mining process for this site requires only one phase, but several levels or lifts. This phase is broken down into three smaller steps with the corresponding timeline: a) Strip topsoil/overburden and stockpile it - approximately 1 year b) Dig dewatering ditches and haul off dry material until the bottom of gravel deposit is reached - approximately 10 years c) Slurry wall to be installed as finances allow (ideally in the first 25% of mine's excavation) — approximately 1 year post mining Tollgate Pit DRMS 112 Permit Application Page D-2 Equipment and Facilities There will be no permanent structures associated with the mining. Temporary equipment will vary from time to time depending on mining phase. These include but are not limited to the following: Earth Moving Equipment • CAT 623 Scraper • Cat 980G Wheel Loader • CAT 972G Wheel Loader • CAT 140G Blade • CAT D6 Dozer Operational Equipment • Water Trucks • Dewatering Pumps • CAT 330B Excavator • CAT 235 Excavator • Mack Tandem Axel Dump Trucks • Belly Dump • Aggregate Bins • Diesel Powered Generators Tollgate Pit DRMS 112 Permit Application Page D-3 EXHIBIT E RECLAMATION PLAN Introduction This site will be mined and reclaimed in order to create a stable and sustainable environment. The proposed final land uses for the site are water storage and residential. There will be two parts to the reclamation process on this site. The first will initiate during the beginning of mining and will consist of the creation of a slurry wall around the mine boundary. The slurry wall may be constructed before mining begins, or afterwards as finances allow. The slurry wall will minimize the need for dewatering as mining progresses down, and will also allow the storage of water post mining. The overall reclamation, focusing on topsoil placement and revegetation with drought -tolerant native or adaptive plant species, will commence at the end of all mining due to the single mining phase. Since mining, agriculture, water storage, and residential are the common land uses in this area, the proposed reclamation will be appropriate in this location. Site reclamation concepts are detailed Exhibit F — Reclamation Plan Map. The estimated acreage to be topsoiled will be approximately 4.62 acres, assuming a perimeter of 4,240 linear feet and 47.5 feet of shoreline. The final size of the water storage area will be quite similar to the original boundary. The shape will change slightly to conform to the owner's requirements for future use. The main access road to the mine, off O Street, will likely remain as is after mining is complete. If there are any additional roads throughout the site that will not be necessary for future access, they will be reclaimed with vegetative cover to stabilize the soil and minimize erosion. The following sections provide additional information to be in accordance with Rule 3.1 within the Rules and Regulations. Time Limit and Phased Reclamation As stated by section 3.1.3, each phase of reclamation shall be completed within five years. This five year period will be applied separately to the slurry wall and the final site revegetation. If any extension is desired for one of these two phases, the Board or office will be contacted. Reclamation Measures — Material Handling Site grading will be performed to create a final topography appropriate with the proposed final land uses. Excess overburden will be available to create the final reclamation boundary desired by the land owner. Stockpiled topsoil will also aid in creating the final reclamation site. If applicable, the applicant will provide to the Division the appropriate notices and affidavit certifying that the material used for topsoil is clean and inert in accordance with Rule 3.1.5(9) of the Rules and Regulations. Final grading will take place after mining is completed, approximately 10 years from the start in 2019. Since the site will be mined at a 3:1 slope, the need for backfill will be limited. Once grades are acceptable, all slopes will be covered with 6-12 inches of topsoil, down to the estimated high water line, Tollgate Pit DRMS 112 Permit Application Page E-1 to provide a growing medium for re -vegetation. Scrapers will be used to place the backfilled overburden and topsoil. All grading activities will be done in a manner to control erosion on the impacted land. Seed will then be placed to revegetate the disturbed areas. The seeding phase will be completed during the first favorable seeding season following the topsoil placement. Until vegetation has been established, temporary irrigation may be necessary to aid in the initial growth of the plants. Other disturbed areas, such as the stockpile area or roads not needed for future access, will be scarified and covered with topsoil to be re -vegetated. Again, wherever topsoil is replaced, it will consist of a 6-12 inch layer. No high walls, auger holes, toxic materials, adits or shafts will be on site during or after the mining is complete. No pollutants will be released to groundwater from any mined materials. Reclamation quantities and costs are summarized in Exhibit L. Water Any disturbances to the prevailing hydrologic balance of the affected land and surrounding area will be minimal. Bucklen will remain in compliance with all applicable Colorado water laws and regulations governing injury to existing water rights during and after mining. Such compliance may include acquisition of a temporary Substitute Water Supply Plan (SWSP). In addition, the mining operation shall be in compliance with federal and Colorado water quality laws and regulations and dredge and fill requirements. No earth dam will be necessary to impound water on the site. All stockpile areas throughout the surface of the permit boundary will be stabilized through compaction and protected to control erosion. At this time, no mining or reclamation plans should cause any impact on the groundwater quality. Wildlife All reclamation aspects will take into account the safety and protection of wildlife on the site. The area to be mined consists of historically irrigated cropland that does not serve as wildlife habitat. According to the National Wetlands Inventory (https://www.fws.gov/wetlands/) there is a strip of riverine habitat along the Storms Lake Drainage Ditch that may be considered jurisdictional wetlands which could house wildlife. Mining operations will maintain appropriate setbacks from this area and therefore is not expected to impact this strip of riverine habitat. During mining, groundwater will be collected and sediment allowed to settle before the water is pumped into the drainage ditch for delivery to the Cache la Poudre River. These dewatering operations are not anticipated to negatively affect this riverine habitat. Topsoiling During the first portion of the single mining phase, topsoil will be removed and stockpiled. This will be removed and segregated from other overburden. Since the topsoil will not be replaced on a backfill area within a short period of time, these stockpiles will receive erosion control measures. It is important to make sure that this topsoil remains in a usable condition for the reclamation. The stockpile locations will be located in the southwest corner of the site, shown in Exhibit C — Mining Plan Map. This area will have minimal disturbance from ongoing mining operations. If required for stabilization, immediate planting of Tollgate Pit DRMS 112 Permit Application Page E-2 annual and/or perennial vegetation on topsoil stockpiles will occur. Once the topsoil is stockpiled, it will be left alone until the reclamation occurs at the end of the mining period. Following mining, the topsoil will be relocated to the finalized slopes at a depth of 6-12 inches. To eliminate slippage zones between deposited topsoil and textured spoil surfaces, topsoil will be replaced to assure stability. Revegetation Following the replacement of topsoil, reseeding will be performed. The revegetation which will occur on site will be capable of self regeneration without continued dependence on irrigation, soil amendments, or fertilizer. A native seed mix will be used to ensure this concept is fulfilled. Grass seed shall be planted in unfrozen soil between October 1 and April 30 using a grass drill or broadcast seeder. The plan for this site is to use a variety of dryland grass seed. These include but are not limited to: • Western Wheatgrass • Sideoats Grama • Big Bluestem • Blue Grama • Indian Grass • Switchgrass • Sand Dropseed • Little Bluestem • Buffalo Grass • Green Needle Grass • Mountain Muhly These species are subject to change based on availability at the time revegetation will occur on site. Areas around the edge of the water surface are expected to establish marsh and aquatic plants themselves. Species of plants anticipated to occur naturally along the shoreline include cattails, willows, cottonwoods, and bulrushes. Ideally, these plants will minimize shoreline erosion potential. If no native species establish naturally along the shoreline, additional planting may include willows, cotton -less cottonwood, choke cherry, or other suitable vegetation. Buildings and Structures There will be no buildings or structures left on site post mining. Signs and Markers All necessary signs and markets will be in place in accordance with the Rules and Regulations. These include: • Entrance of mine site • Boundaries of affected area Spills Reporting Tollgate Pit DRMS 112 Permit Application Page E-3 Though there will likely be no toxic or hazardous substances throughout this site, the mine operator will notify the Office if a spill is encountered within the mined land permit area, as well as, follow all other necessary requirements. Weed Management Weed control measures will be implemented to ensure no prohibited noxious weed species preventthe development of desired vegetation. Such weed control measures may include a combination of both chemical and mechanical methods. Site evaluations will be conducted annually to maintain control of and/or eradicate noxious weeds, including Canada Thistle, Musk Thistle, Field Bindweed, Salt Cedar, Russian Olive, Leafy Spurge, Kochia, and Cheatgrass.

The depth to groundwater varies from 14 to 19 feet below the surface. The Cache La Poudre River is approximately 1 mile (at the closest) to the southern boundary of the parcel which will be mined. The duration of mining will last approximately 10 years. To enable dry mining throughout the site, dewatering trenches will be constructed around the perimeter of the pit. Water from these trenches will be discharged to the Storms Lake Drainage Ditch shown in Exhibit B and Exhibit C. This will be done in accordance with a Colorado Department of Public Health and Environment water quality permit, Colorado Discharge Permitting System (CDPS), which will be obtained prior to the commencement of mining. An 8 -inch pump operating on a continuous basis will dewater the pit as mining takes place. Near the discharge on the outfall pipe there will be a water meter to measure the quantity of water that is pumped out of the pit. Additionally, there will be a spare pump on standby used intermittently in the event that stormwater increases the amount of water in the pit requiring additional dewatering. Potential pollutants in the dewatering discharged will be controlled in accordance with the CDPS permit. After initial dewatering, the only exposed surface water will be in dewatering trenches and settling ponds, which are anticipated to be a maximum of 1 acre in area. According to the National Flood Insurance Program (NFIP) Flood Insurance Rate Map (FIRM) for the area (Map Number 08123C 1508E), the western half of the proposed permit boundary lies within the Zone A floodplain (commonly called the 100 -year floodplain). Pursuant to the Chapter 23, Article XI of the Weld County Code, any development within the floodplain at this location (which includes mining, dredging, filling, grading, paving, excavation, or drilling operations or storage of equipment or materials) require a Flood Hazard Development Permit (FHDP) be issued by Weld County. Said FHDP will be obtained prior to the commencement of mining. Known Aquifers The southern portion of the proposed permit boundary overlies the alluvial aquifer for the Cache la Poudre River. There are no other known aquifers at this location. Water Requirements Consumptive use of water at the site will result from evaporative loss, water retained in mined product, and water used for dust control of internal haul roads and stockpiles. Evaporative losses are dependent on the exposed water surface area, which may vary throughout the mining operation. The exposed surface area from dewatering trenches and settling ponds is anticipated to be no more than 1 acre. According to NOAA Technical Report NWS 33 ("Evaporation Atlas for the Contiguous 48 United States"), the gross annual evaporation for this area is approximately 43 inches. According to precipitation isohyetal data in the Colorado Decision Support System (CDSS), average Tollgate Pit DRMS 112 Permit Application Page G-1 annual precipitation in the area is 12 inches per year. Pursuant to C.R.S. §37-92-305(12)(a), sand and gravel mining operations may claim a credit against gross evaporation for the historic natural depletion from pre-existing natural vegetative cover eradicated by the mining operation; the Division of Water Resources (DWR) typically allows a credit claim equivalent to 70% of total precipitation. Therefore, the net evaporative loss rate for this site is estimated to be 2.88 feet per year. For 1 acre of exposed surface area, the net evaporative loss is 2.88 acre-feet per year. The annual production from the Tollgate Pit site is estimated to be 250,000 tons. The moisture content of the material hauled off the site is assumed to be four percent by weight and results in an annual volume of 7.36 ac -ft of water retained in the mined product. Dust control will be required for internal haul roads and stockpiles and is estimated to toal 1.5 ac -ft per year. The total quantity of water to be consumed during the mining operation is estimated to be 11.74 ac -ft per year, as shown in Exhibit G-1. Exhibit G- I Annual Water Requirements at Tollgate Pit Evaporation from 1 acre 2.88 ac -ft Moisture retained in product 7.36 ac -ft Dust control 1.5 ac -ft Total 11.74 ac -ft Replacement Water Depletions will accrue to the Cache la Poudre River upstream of the GIC headgate. During the irrigation season the GIC is a common location for a river call, so replacements in that season must enter the river at that point or above it. During the non -irrigation season the common call location is far downstream on the South Platte River, so the replacements in that season can enter the stream system further downstream if necessary. The following sources may be used to provide necessary replacement water for the site: • Whitney Ditch Company shares • New Cache la Poudre Irrigating Company shares • Fully consumable replacement water from the City of Fort Collins, the Town of Windsor, the City of Greeley, the City of Aurora, or others • Excess augmentation credit generated by nearby gravel pit SWSPs Surrounding Water Rights Permitted wells within 1/2 mile of the site are shown in Exhibit G-2. The location of these wells is also shown on Exhibit B. This data was found using the State of Colorado's Well Permit Search Map Viewer. There may be other wells within the defined area, but they are not registered nor permitted with the State Engineer's Office. If the slurry wall is not installed prior to mining, then a well permit will be required for the proposed gravel pit. This well permit will be obtained prior to the commencement of mining.

Groundwater Monitoring In January of 2008, Aggregate Industries-WCR, Inc. installed three monitoring wells (denoted MW -15, MW -16, and MW -20) on the parcel. The well permits associated with these wells are shown in the below table, and are displayed on the Exhibit B Index Map. Monitoring Well ID Well Permit No. Remark MW -15 276587 Well has silted in, not useable in present state MW -16 276588 Actively monitored through June 2018 MW -20 276592 Actively monitored through June 2018 Aggregate Industries-WCR, Inc. incorporated these monitoring wells into their existing monthly monitoring program for the Riverview Resource Operation (M-1999-098) and continued to monitor them on a monthly basis until the DRMS released the property from the permit. Bucklen Services Company (Bucklen) intends to take over monitoring responsibilities, and will continue to monitor the wells on a monthly basis until reclamation is complete and the DRMS releases the financial warranty bond, or portions thereof for which certain well monitoring data is no longer deemed necessary by the DRMS. If additional groundwater data is needed, Bucklen may also utilize data from other monitoring wells located on the adjacent Riverview Resource Operation (M-1999-098) that continue to be monitored by Aggregate Industries-WCR, Inc. The objectives of the well monitoring program are to monitor groundwater conditions and provide a basis for assessing the impacts of mining on surrounding groundwater. Through the well monitoring program, pre -mining groundwater elevations, flow patterns across and near the property, and seasonal fluctuations have been, and will continue to be, documented. Wells Within 600 Feet In accordance with C.R.S. §37-90-137(2), owners of wells within 600 feet of the proposed extraction cells will be identified and receive notification in conjunction with the new well permit application for the gravel pit. If requested by the well owner, Bucklen will attempt to measure water levels in these wells prior to the commencement of mining. Groundwater Mitigation Monitoring data will be used to identify potential changes in alluvial groundwater flow or elevation associated with mining and reclamation activities. Baseline data collected from the monitoring program Tollgate Pit DRMS 112 Permit Application Page G-5 will provide a range of relative water levels associated with pre -mining groundwater conditions, although such baseline data may be affected by adjacent mining activities. Experience at other sand and gravel mines in similar geologic settings has found that groundwater levels tend to fluctuate between two to four feet each year, being highest in the summer and lowest in the winter and early spring. • If, during mining, the relative seasonal groundwater elevation at any of the domestic wells or monitoring wells differs from the baseline conditions by more than two feet, and the condition was not observed during baseline monitoring, or if Bucklen receives a complaint from any well owner within 600 feet from the site boundary, then Bucklen will evaluate the cause and take action within 30 days and notify the DRMS. • After the DRMS has been notified, Bucklen will review the available data and information and submit a report to the DRMS within an additional 30 days. The evaluation will include discussions with any well owner who has contacted Bucklen regarding a concern, and review of baseline data from the well and vicinity to evaluate whether changes may be due to seasonal variations, climate, mining, or other factors. The report will identify the extent of potential or actual impacts associated with the changes. If the extent of groundwater changesdue to mining or reclamation activities is determined to be a significant contributing factor that has or may create adverse impacts, the mining associated impacts will be addressed to the satisfaction of the DRMS. • Bucklen will begin to implement on or more mitigation measures if mining and reclamation activity is determined to be a significant contributing factor to groundwater changes requiring mitigation. If, however, a subject well has not been put to beneficial use prior to mining, then Bucklen would have no responsibility to provide mitigation. • Mitigation measures may include, but are not limited to: o Cleaning a well to improve efficiency. o Providing an alternative source of water or purchasing additional water to support historic well use in terms of water quantity and quality. If needed, water quality parameters will be checked in affected wells to ensure alternative sources support the historic use. o Modifying a well to operate under lower groundwater conditions. This could include deepening existing wells or lowering the pumps. All work would be done at Bucklen's expense with the exception of replacing equipment that was non-functional prior to mining. o If existing wells cannot be retrofitted or repaired: replacing the impacted well with a new replacement well. o Providing flood irrigation to address concerns over impacts to sub -irrigated lands adjacent to the site. • If a groundwater mitigation action is required, Bucklen will notify the DRMS of the condition, action taken, and result. Tollgate Pit DRMS 112 Permit Application Page G-6 EXHIBIT H WILDLIFE INFORMATION All reclamation aspects will take into account the safety and protection of wildlife on the site. The area to be mined consists of historically irrigated cropland that does not serve as wildlife habitat. According to the National Wetlands Inventory (https://www.fws.gov/wetlands/) there is a strip of riverine habitat along the Storms Lake Drainage Ditch that may be considered jurisdictional wetlands which could house wildlife. Mining operations will maintain appropriate setbacks from this area and therefore is not expected to impact this strip of riverine habitat. During mining, groundwater will be collected and sediment allowed to settle before the water is pumped into the drainage ditch for delivery to the Cache la Poudre River. These dewatering operations are not anticipated to negatively affect this riverine habitat.

Examples are bedrock. cemented layers, dense layers, and frozen layers. This theme presents the depth to any type of restrictive layer that is described for each map unit. If more than one type of restrictive layer is described for an individual soil type, the depth to the shallowest one is presented. If no restrictive layer is described in a map unit. it is represented by the "> 200" depth class. This attribute is actually recorded as three separate values in the database. A low value and a high value indicate the range of this attribute for the soil component. A "representative" value indicates the expected value of this attribute for the component. For this soil property. only the representative value is used.

Effective management is based on the relationship between the soils and vegetation and water. This table shows, for each soil that supports vegetation, the ecological site. plant association, or habitat type; the total annual production of vegetation in favorable, normal. and unfavorable years: the characteristic vegetation: and the average percentage of each species. An explanation of the column headings in the table follows. An ecological site. plant association, or habitat type is the product of all the environmental factors responsible for its development. It has characteristic soils that have developed over time throughout the soil development process: a characteristic hydrology. particularly infiltration and runoff that has developed over time: and a characteristic plant community (kind and amount of vegetation). The hydrology of the site is influenced by development of the soil and plant community. The vegetation, soils, and hydrology are all interrelated. Each is influenced by the others and influences the development of the others. The plant community on an ecological site, plant association, or habitat type is typified by an association of species that differs from that of other ecological sites, plant associations. or habitat types in the kind and/or proportion of species or in total production. Descriptions of ecological sites are provided in the Field Office Technical Guide, which is available in local offices of the Natural Resources Conservation Service (NRCS). Descriptions of plant associations or habitat types are available from local U.S. Forest Service offices. Total dry -weight production is the amount of vegetation that can be expected to grow annually in a well managed area that is supporting the potential natural plant community. It includes all vegetation. whether or not it is palatable to grazing animals. It includes the current year's growth of leaves, twigs, and fruits of woody plants. It does not include the increase in stem diameter of trees and shrubs. It is expressed in pounds per acre of air-dry vegetation for favorable, normal, and unfavorable years. In a favorable year. the amount and distribution of precipitation and the temperatures make growing conditions substantially better than average. In a normal year. growing conditions are about average. In an unfavorable year, growing conditions are well below average. generally because of low available soil moisture. Yields are adjusted to a common percent of air-dry moisture content. Characteristic vegetation (the grasses, forbs. shrubs, and understory trees that make up most of the potential natural plant community on each soil) is listed by common name. Under rangeland composition and forest understory, the expected percentage of the total annual production is given for each species making up the characteristic vegetation. The percentages are by dry weight for rangeland. Percentages for forest understory are by either dry weight or canopy cover. The amount that can be used as forage depends on the kinds of grazing animals and on the grazing season. \ Natural Resources Web Soil Survey a Conservation Service National Cooperative Soil Survey 5/14/2018 Page 1 of 4 Rangeland and Forest Vegetation Classification, Productivity, and Plant Composition ---Weld Tollgate Pit County, Colorado, Southern Part Range management requires knowledge of the kinds of soil and of the potential natural plant community. It also requires an evaluation of the present range similarity index and rangeland trend. Range similarity index is determined by comparing the present plant community with the potential natural plant community on a particular rangeland ecological site. The more closely the existing community resembles the potential community, the higher the range similarity index. Rangeland trend is defined as the direction of change in an existing plant community relative to the potential natural plant community. Further information about the range similarity index and rangeland trend is available in the "National Range and Pasture Handbook," which is available in local offices of NRCS or on the Internet. The objective in range management is to control grazing so that the plants growing on a site are about the same in kind and amount as the potential natural plant community for that site. Such management generally results in the optimum production of vegetation. control of undesirable brush species, conservation of water, and control of erosion. Sometimes, however, an area with a range similarity index somewhat below the potential meets grazing needs. provides wildlife habitat. and protects soil and water resources.

Described in more detail in Exhibit E — Reclamation Plan, the reclamation will consist of adding a slurry wall around the mined area in order to create a lined gravel pit reservoir before or at the start of mining. After mining is complete, reclamation will only require minimal blade work, topsoiling and seeding. Tabel L-1 describes these tasks in more detail. Exhibit L- 1. Post -Mining Reclamation Tasks. Task Approximate Quantity Cost Total Minimal Site Grading 20 hours $150/hr $3,000 Topsoiling 32 hours* $200/hr $6,400 Seeding 12 lbs of seed/acre + contract planter $4/lb + $100/acre -$10,000 Approximate Total $19,400 *32 hours is calculated based on 4.62 acres needing to be covered with 6-12 inches of topsoil, assuming 10 loads per hour and 23 CY per load. Based on current knowledge of the site, the estimate to design and build the slurry wall around the site is approximately $1,084,000. This piece of reclamation will be completed prior to mining or shortly after mining has begun. The total for reclamation on site, including the slurry wall design and installation and post mine clean-up, is approximately $1,103,400.

The stability analysis was performed in order to evaluate potential for damage to existing permanent structures due to mine highwall slope failures for mining conditions and reclaimed conditions. There is an inverted siphon which currently runs through this site. This pipeline will need to be rerouted, which is shown in Exhibit C — Mining Plan Map. There is an old DCP oil and gas well and line which runs north and south through the middle of the property. The well has been plugged and abandoned but the line will need to be removed. This information was clarified with DCP. Below is a list of all manmade structures on or within 200 feet of mine permit boundary. This information can also be found in Exhibit C — Mining Plan Map. • Great Western Railway • Gas line — Suncor Energy • Gas Line — Public Service • Pipeline easement — Kinder Morgan • Gas Line — Snyder Oil • Farm house and buildings — Allison Albert IV • Gas line — Noble/DCP-Midstream • Tank Battery — Nobel • Storms Lake Drainage Ditch — Greeley Irrigation CO • Overhead electric — Western Area Power Authority • Whitney Siphon • Natural Gas pipeline — Tallgrass Energy Details of the analysis, along with graphic profiles, can be found in Exhibit S-1: Stability Analysis Memorandum. Following the analysis, it was determined that all Factors of Safety are greater than 1.2 and the minimum failure surface does not extend beyond the crest of the slopes. Mining should not pose a hazard to any nearby structures. These results are consistent with those outlined in the previous stability analysis preformed on this site for the Riverview Resources Operation mining permit (M-1999-098).

Tollgate Pit DRMS 112 Permit Application Page 6.5-1 rvs Applegate Group, inc. Water Resource Advisors for the West Exhibit S-1 Stability Analysis Memorandum Date: June 7, 2018 To: Jared Dains, P.E. RE: Tollgate Pit Slope Stability Analysis AG Job No.: 18-110 From: Tyler Desiderio, P.E. Slope stability analysis of the proposed Tollgate Pit site was performed by Applegate Group with the purpose of determining potential impacts to permanent structures within 200 feet of the mined slopes. Proposed site plans, boring logs, and a previous permit on the same site (M-1999-098) were utilized in conjunction with Rocscience Slide 6 software to develop slope stability models of the most critical sections expected at the site. The following discussion summarizes the slope stability analysis performed by Applegate Group. CRITICAL SECTION GEOMETRY & MATERIALS DRMS Permit M-1999-098, prepared by Tetra Tech, contained 8 bore logs of exploratory drillings on the Tollgate Pit site which were reviewed to determine the most critical sections. It was determined that the bore logs titled THW-4 and THW-5 represented the most critical conditions on site as they contained the deepest depths to bedrock and significant amounts of overburden; the major difference between these bore logs is that THW-5 consists of primarily SC and SM overburden while THW-4 consists of mostly CL overburden. Bore logs THW-4 and THW-5 are shown in Figures 7 & 8 attached to this memo. Two slope stability models representing each of the aforementioned bore logs were generated assuming they would be mined to bedrock at 3H:1V slopes, as indicated by the operator. Slope and material geometry of each section are shown in FIGURES 1 & 2 below. r8 4 to w Material Name Color Unit Weight (��) Strength Type Cohesion (PsfJ Phi (deg) Overburden Sand i -: 114 Mohr -Coulomb 0 28 Sand & Gravel 0 130 Mohr -Coulomb 0 35 Weathered 8edrodt ® 124 Mohr Coulomb 0 14 Bedrock ii 124 Mohr -Coulomb 100 28 Overburden Clay n 114 Mohr -Coulomb 50 28 FIGURE I: THW-4 SECTION GEOMETRY www.applegategroup.com 1490 West 121s' Avenue, Suite 100 Denver, CO 80234 (303) 452-661 1 $1 uo Material Name Color Unit Weight (Ibs/rt3) Type Cohesion (Psi) Phi (deg) Overburden Send J 114 MoMtoulomb 0 28 Sand & Gravel Ea 130 Mohr -Coulomb 0 35 Weathered Bedrock 124 Mohr -Coulomb 0 14 Cl Bedrock (t 124 Mohr -Coulomb 100 28 FIGURE 2: THW-5 SECTION GEOMETRY SCENARIOS The following scenarios were analyzed for each critical section: • Mined Condition represents the site during mining and excavation operations with slopes at 3H:1V assuming a steady state condition. Ground water is modeled as shown in the bore logs at the crest of the slope and draws down to the toe of the slope to mimic dewatering operations. A surcharge load of 250 psf was included to approximate HS -20 loading above the slope. • Reclaimed Condition represents the site after mining operations are complete and the site is reclaimed into a reservoir. This only differs from the previous scenario in that ground water and ponded water are modeled at a level 5ft below the slope crest. SOIL STRENGTH PARAMETERS In the absence of soil strength testing data, strength values were assumed for the slope stability models based on bore logs, engineering judgement, and strength values used in the previous permit. Soil strength parameters used in the analysis are summarized in the table below: Material Moist Density (pcf) Saturated Density (pcf) Cohesion (pst) Phi Angle (deg) Sand Overburden' 114 126 0 28 Clay Overburden? 114 126 50 28 Sand and Gravel? 130 137 0 35 Weathered Bedrock2 124 134 0 14 Bedrock2 124 134 100 28 Notes: Values are similar to 'Clay Overburden' but with cohesion removed to represent more granular material 2 Values taken from DRMS Permit M-1999-098 www.applegategroup.com 1490 West 121,' Avenue, Suite 100 Denver, CO 80234 (303) 452-6611 RESULTS & CONCLUSION Rocscience Slide 6 software was used to analyze the slope stability models of Tollgate Pit to determine the lowest Factor of Safety according to the Bishop Method. The lowest Factor of Safety for each model and scenario discussed above are shown in Figures 3 through 6 and are also summarized in the table below: Model THW-4 THW-4 THW-5 THW-5 Scenario Mined Condition Reclaimed Condition Mined Condition Reclaimed Condition FOS 1.38 1.82 1.23 1.59 The lowest Factors of Safety produced by this analysis are all greater than 1.2 and the minimum failure surface don't extend beyond the crest of the slopes. This analysis indicates that the proposed mining operations at the Tollgate Pit site don't pose significant danger to adjacent permanent structures.

The application was called complete for review on November 15, 2018. All comment and review periods began on November 15, 2018. The decision date for this application is February 15, 2019. Please be advised that if you are unable to satisfactorily address any concerns identified in this review before the decision date, it will be your responsibility to request an extension of the review period. If there are outstanding issues that have not been adequately addressed prior to the end of the review period, and no extension has been requested, the Division will deny this application. In order to allow the Division adequate time to review your responses to any adequacy issues, please submit your adequacy responses to the Division no later than one week prior to the decision date (February 7, 2019). Please note that any changes or additions to the application on file in our office must also be reflected in the public review copy, which has been placed with the Weld County Clerk and Recorder. The review consisted of comparing the application content with specific requirements of Rule 6.1, 6.2, 6.4 and 6.5 of the Minerals Rules and Regulations of the Colorado Mined Land Reclamation Board for the Extraction of Construction Materials. In general the application was substantially adequate; however, as with most applications there are a few items that will require clarification of the existing information. Any inadequacies are identified under the respective exhibit heading. EXHIBIT C - Pre -mining and Mining Plan Map(s) of Affected Lands (Rule 6.4.3): One or more maps may be necessary to legibly portray the following information: (a) all immediately adjacent surface owners of record; 1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us John W. Hickenlooper, Governor I Robert W. Randall, Executive Director I Virginia Brannon, Director Jared Dains December 18, 2018 Page 2 of 5 (b) the name and location of all creeks, roads, buildings, oil and gas wells and lines, and power and communication lines on the area of affected land and within two hundred (200) feet of all boundaries of such area; (g) Show the owner's name, type of structures, and location of all permanent or man-made structures contained on the area of affected land and within two hundred (200) feet of the affected land. Please review at least the above sections for completeness and accuracy and revise as necessary. Please also make sure that all figures comply with the requirements for exhibits listed in Rule 6.2.1. EXHIBIT D - Mining Plan (Rule 6.4.4): The mining plan shall supply the following information, correlated with the affected lands, map(s) and timetables: (a) description of the method(s) of mining to be employed in each stage of the operation as related to any surface disturbance on affected lands; Please note that topsoil must be salvaged and maintained from all affected areas, including areas to be utilized for stockpiles and roadways, for use in final reclamation. The permittee will need to commit to the timing for the installation of the slurry wall as it relates to the mining plan and exposure of groundwater at the site — stating that the slurry wall will be installed before, or after, mining is insufficient. The permittee should commit to a maximum working mining slope of 3:1 horizontal to vertical within the mining plan. The reclamation plan states that mining will take place at 3:1 H:V, but this statement is nowhere in the mining plan as submitted. If nothing is specified in the mining plan, the Division may need to assume that the entire shoreline/excavated perimeter will need to be re -sloped from a 1.5:1 working face to a 3:1 reclamation slope and calculate the bond accordingly. The earthwork required to reconstruct a final reclamation slope of 3:1 H:V within the excavated area usually constitutes a significant portion of the reclamation bond. EXHIBIT E - Reclamation Plan (Rule 6.4.5): The reclamation/revegetation plan will need to address reclamation for all affected areas, including access roads and stockpile areas, not just the excavated area as currently provided. The reclamation plan must provide the amount of pure live seed (PLS) by species, per acre, to be utilized for revegetation. Be aware that amount of PLS given for drill seeding may be doubled for broadcast seeding, so be sure to specify what seeding method the amounts given are intended to be utilized for. Jared Damns December 18, 2018 Page 3 of 5 Because the post -mining land use contains a lined reservoir within the flood plain, armored inlet/outlet structures will need to be included as a key design feature for the reservoir. These structures are required to provide a pathway for flood flows to enter and leave the lined reservoir while preventing damage to the slurry wall. Costs to design/build these structures will also need to be included in the reclamation bond estimate, and they will need to be shown on the reclamation plan map as appropriate. EXHIBIT F - Reclamation Plan Map (Rule 6.4.6): The map(s) of the proposed affected land, by all phases of the total scope of the mining operation, shall indicate the following: (a) The expected physical appearance of the area of the affected land, correlated to the proposed mining and reclamation timetables. The map must show proposed topography of the area with contour lines of sufficient detail to portray the direction and rate of slope of all reclaimed lands. EXHIBIT G - Water Information (Rule 6.4.7): According to the well information presented in Exhibit B and Table G-2 there appear to be several other monitoring wells (wells 2-8, 25, 21, and 22 specifically) that are located either on, or very near, the proposed permitted area. Why were these wells not included in a groundwater monitoring plan? Groundwater Monitoring/Mitigation Plan comments: Please specify what wells will he utilized in the monthly groundwater level monitoring plan described. It appears that at least one of the monitoring wells currently listed (MW -15) is unusable. Will that well be repaired or replaced? DRMS requires, at a minimum, 5 consecutive quarters of baseline groundwater level data prior to dewatering to establish pre -mining conditions on -site at the chosen monitoring locations. If you can provide this data utilizing existing wells/data please do so, otherwise, please commit to providing the required 5 quarters of data prior to dewatering activities on -site. The 30 day notification period specified in the plan for Bucklen to evaluate/take action and notify DRMS in the event of a complaint of an impacted well is not acceptable. Please commit to no more than 5 working days to initiate action and notify DRMS, in writing, in the event of a complaint of an impacted well. DRMS also cannot accept the condition that wells must have been put to beneficial use prior to mining to be eligible for mitigation if impacted. If a well has been appropriately permitted by the State Engineer's Office it must be mitigated if impacted. It may be in Bucklen's interest to conduct pre -mining assessments of nearby wells, if access can be obtained, to document information such as Jared Damns December 18, 2018 Page 4of_5 static water levels and yield under pre -mining conditions. This information may be especially useful if there is reason to believe that the well may be impaired prior to mining within this proposed permit area. EXHIBIT L - Reclamation Costs (Rule 6.4.12): (1) All information necessary to calculate the costs of reclamation must be submitted and broken down into the various major phases of reclamation. You must provide sufficient information to calculate the cost of reclamation that would be incurred by the state. You will need to specify, at a minimum, how many acres will require topsoil replacement, cubic yards of topsoil to be moved, average haul distances from stockpile locations, etc. This assumes that the site was mined at no steeper than 3:1 working slopes and therefore backfilling to final slopes using excess overburden is not required. Pounds of PLS for each species of reclamation vegetation will need to be provided, along with any mulch (generally 2 tons/ac crimped straw), or other soil amendments to be used for revegetation. Mobilization/Demob for all required equipment. DRMS will require documentation to substantiate the estimate given for the installation of the slurry wall. This is usually provided as a copy of the R.F.P. which provides site specific conditions, and the bids provided to complete the work. DRMS may alternately utilize a cost of $5-$6 per square foot for slurry wall installation based on the perimeter of the proposed wall and average depth to bedrock. DRMS will also include indirect costs of approximately 21% in the total required bond amount.

RE: Tollgate Pit, File No. M-2018-060 Applicant/Operator: Bucklen Services Company, Inc.; (970) 353-0720 SW/ of Section 29, Twp 6 North, Rng 66 West, 6th P.M., Weld County CONDITIONS FOR APPROVAL The proposed operation will consume ground water by: evaporation, N dust control, f,slurry wall construction, El water removed in the mined product, ❑ processing: Prior to initiation of these uses of groundwater, the applicant will need to obtain either a gravel pit or other type of well permit, as applicable. However, prior to obtaining a permit, an approved substitute water supply plan or decreed plan for augmentation is required. Prior to approving a well permit, the applicant must conduct a field inspection of the site and document the locations of all wells within 600 feet of the permit area. The applicant must then obtain a waiver of objection from all well owners with wells within 600 feet of the permit area or request a hearing before the State Engineer. If stormwater runoff is intercepted by this operation and is not diverted or captured in priority, it must be released to the stream system within 72 hours; otherwise the operator will need to make replacements for evaporation. COMMENTS: The subject application is for a surface mining operation on 60 permitted acres known as the Tollgate Pit, file no. M-2018-060, located approximately 5.6 miles NW of the City of Greeley. The primary commodity to be mined at the site is aggregate for construction materials. The present land use at the site is cropland and the proposed post -mining use is a developed water resource. The proposed mining operations will predominately occur below the groundwater table and will impact groundwater hydraulically connected to the Cache la Poudre River ("River"). The site is proposed to be dry mined using dewatering trenches that will be constructed around the perimeter of the site and will be discharged to the adjacent Storms Lake Drainage Ditch, which travels approximately 0.5 miles before discharging to the River. A slurry wall will be constructed around the mine boundary, either before mining begins or afterwards as finances allow. If the slurry wall is not constructed and approved prior to the commencement of mining, groundwater will be consumed at the site by way of evaporation, water retained in the mined product, and dust control. The total estimated annual amount of water to be consumed is 11.74 acre-feet. Prior to the use/exposure of any groundwater at the site, the applicant must first obtain a well permit and a valid substitute water supply plan or decreed plan for augmentation. 1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 www.colorado.gov/water John W.

These responses follow the same order as outlined in the adequacy review. EXHIBIT C — Pre -mining and Mining Plan Map(s) of Affected Lands (Rule 6.4.3): In order to ensure that all underground utilities within 200 ft of the affected lands have been accounted for, an 811 engineer's request was put in on December 20, 2018. The mining plan map has been broken into two maps; Figure C-1 shows the adjacent property owners and Figure C-2 shows the mining plan and structures within 200 ft. See the two updated maps attached. EXHIBIT D — Mining Plan (Rule 6.4.4): The following is additional information regarding the original proposed methods of mining to be employed in each stage of the operation as related to any surface disturbance on the affected lands. The slurry wall will be constructed prior to the start of mining. The construction will take approximately two to three months and will be followed by a 90 -day leak test, resulting in approximately six months total from the start of slurry wall construction until mining may begin. The approximate 6 to 12 inches of topsoil will be stripped off and stockpiled in the southern most portion of the stockpile area. The topsoil will be salvaged and maintained from all affected areas, including those to be utilized for stockpile and roadways, for final reclamation. Next, the overburden will be removed from the ground and stockpiled separately but next to the topsoil stockpile. Note that these two separate stockpiles will both be kept stabilized, so no excessive erosion occurs. The area will be mined with a maximum working slope of 3H:1 V around the entire perimeter of the mine boundary. Due to this, there will be no need for the entire perimeter to be re -sloped post mining during reclamation. EXHIBIT E — Reclamation Plan (Rule 6.4.5): Reclamation activities will take place in all affected areas, which includes access roads and stockpile areas. The amount of area to be topsoiled and seeded is conservative to include not only the shoreline area, but also the stockpile area, the crossing, and the armored inlet channel described in more detail below. www.applegategroup.com Denver • Glenwood Springs • Hotchkiss (303) 452-661 Eric Scott RE: Response to Preliminary Review of a 112 Construction Materials Reclamation Permit Application Package, Tollgate Pit, File No. M-2018-060 February 15, 2019 Page 2 of 7 Table 1 below describes the suggested native grass seed mix from the USDA-NRCS to be used on the site.' The soil in the area is predominately loamy, which was a driver for the seed selection. Note this seeding guide is for a Native Grass Drill; if seed is planted via broadcast methods, then all pounds of live seed rates should be doubled. The full recommendation, which includes alternatives, is on file if needed. The Rangeland Management Specialist with the USDA-NRCS did not recommend mulch or other soil amendments, yet a cover crop for the first year is recommended in order to protect and enhance the soil. The cover crop shall be planted in the spring and allowed to grow and frost die off. The following fall, the native seed mix shall be planted. TABLE I. USDA-NRCS RECOMMENDED SEED M/X.

As shown in Figure 1 below, FEMA's National Flood Hazard Layer indicates that the potential for flooding in the area is due to backwater filling and then overtopping the nearby Storms Lake Drainage. This overtopping is likely to first occur at the southwest portion of the site where ground elevations are lowest. Once Storms Lake Drainage overtops, a side channel spillway will direct the water to a controlled and armored section which will allow flood flows into the pit while protecting the pit slopes and slurry wall.

Caddo tame No tSS. ems aro Se In accordance with the UDFCD guidelines, a side channel spillway with a 100 -foot bottom width and 3H:1 V side slopes was determined to be necessary. The location of the side channel spillway is near the southwest corner of the pit, corresponding to the location where overtopping of Storms Lake Drainage is expected to first occur. In order to not decrease the carrying capacity of Storms Lake Drainage, the spillway channel will begin to the east of Storm's Lake Drainage's easement. The spillway channel will have an approximate 3% slope towards the east into the mined area, and will primarily be vegetated for most of the length. Near the start of the spillway rundown to the pit, the vegetated channel bottom will transition to Type M riprap, a concrete cutoff wall, and finally a spillway -grade concrete rundown along the 3:1 mined slope to a point 5 feet below the high water mark; here the rundown will transition back to Type M riprap to the bottom of the mined area. The length of the concrete channel transition from the edge of the pit is to be determined depending on the location of the slurry wall. For cost estimating purposes, this length is assumed to be 10 feet from the edge of the pit with another 5 feet to the concrete cutoff wall. Note that the specified design utilizes one of the slope protection methods (concrete spillway) suggested by the UDFCD. Equivalent spillway protection may also be used, including grouted boulders, soil cement, or concrete pavers. EXHIBIT F — Reclamation Plan Map (Rule 6.4.6): The reclamation plan map (attached, F-1) has been updated in order to show proposed topography of the reclaimed area. The design for the armored inlet channel is also included on this map. EXHIBIT G — Water Information (Rule 6.4.7): www.applegategroup.com Denver • Glenwood Springs • Hotchkiss (303) 452-6611 Eric Scott RE: Response to Preliminary Review of a 112 Construction Materials Reclamation Permit Application Package, Tollgate Pit, File No. M-2018-060 February 15, 2019 Page 4of7 There are several other wells that are located on or near the proposed permitted area but have not been included in the groundwater monitoring plan for the following reasons: • Well #2 was the monitoring hole that was converted into the monitoring well identified as #3 (MW - 16). • Wells # 4, 5, 6 are irrigation wells and thus are not ideal for monitoring well use. Their plotted location from the Division of Water Resources data is based on quarter sections and thus is not exact so they are likely not truly located in the place identified in Exhibit B. • Well #8 was the monitoring hole that was converted into the monitoring well identified as well #23 (MW -17). • Wells #7 (MW -17), #21 (MW -3) and #25 (MW -2) are located on property owned by Aggregate Industries and readings are reported as part of the WW Farms gravel pit (DRMS Permit No. M-99- 098). • Well #22 was the monitoring hole that was converted into the monitoring well identified as #23 (MW -20). Groundwater Monitoring/Mitigation Plan comments: At this time, Bucklen Services is proposing to monitor only the three wells listed in the groundwater monitoring plan (MW -15, MW -16 and MW -20). Note that MW -15 is currently unusable but will be repaired or replaced prior to the commencement of mining. If additional readings are needed to supplement the Tollgate Pit monitoring wells, readings from the WW Farms Pit monitoring wells (MW -2, MW -3 and MW -17) can be obtained from Al's regular reports. Wells MW -15, MW -16 and MW -20 were installed by Aggregate Industries in January 2008 and were continuously monitored by Aggregate Industries until June 2018. This period of continuous readings exceeds the five consecutive quarters requirement. This data was submitted with its regular reports for the WW Farms Pit and will serve as the baseline groundwater data for the Tollgate Pit. Additional data collected by Bucklen prior to mining will serve as a supplement to this baseline data. It has been noted that the 30 -day notification period to evaluate/take action and notify the DRMS in the event of a complaint of an impacted well is no longer standard practice for the DRMS. Bucklen will commit to no more than 5 working days to notify the DRMS, in writing, with the complaint and an action plan. The operator acknowledges that it will be responsible for mitigation of any licensed well that the DRMS determines has been adversely impacted by the operator's mining activities, regardless of the well's use prior to mining activities. EXHIBIT L — Reclamation Costs (Rule 6.4.12): Table 2 is an updated cost estimate for the reclamation on the Tollgate Pit site. The major phases of reclamation will be minimal grading, top soiling and seeding and the construction of the armored inlet/outlet structures. Since the site will be mined with 31-1:1V slopes in all areas, no major grading will be required, only minor blade work on the slopes, around the perimeter of the mine and in the topsoil stockpile location. www.applegategroup.com Denver • Glenwood Springs • Hotchkiss (303) 452-6611 Eric Scott RE: Response to Preliminary Review of a 112 Construction Materials Reclamation Permit Application Package, Tollgate Pit, File No. M-2018-060 February 15, 2019 Page 5 of 7 TABLE 2.

With approximately 4,240 linear feet of mine perimeter, that area equates to 4.62 acres. The topsoil/stockpile area is approximately 3 acres, so the total area required to be topsoiled and seeded is 7.62 acres (conservatively increased to 8 acres in order to include any areas of heavy equipment traffic). These areas will be covered with 6-12 inches of topsoil. The topsoil will be moved a short distance as it is being stored on -site, the travel distance should be no more than 0.4 miles maximum. Operations will consist of 10 loads per hour and 23 cubic yards per load. This equates to approximately 561.16 loads or 56.12 hours. The cost for native seed was calculated using the recommended seed mix from the USDA-NRCS for the project location and estimates of cost per pure live seed (PLS) per species from Pawnee Buttes Seed Inc.' The cost was calculated by converting the cost per PLS per species into a total cost per species for the full reclamation area (approximately 8 acres). A weighted average was calculated based on the percentage of each seed species to use as an approximate estimate for the seed mix. As mentioned, it is recommended that a cover crop is grown in the reclaimed area to create better growing conditions for the native seed. This cost was accounted for by using the same estimate as the native seed, in order to remain conservative. The cost for the armored inlet will include a small amount of grade work, topsoiling and seeding (included in the total for these items), spillway grade concrete, CDOT Class 1 bedding and Type M riprap.

Most material cost estimates were pulled from the UDFCD Bid Item Pricing spreadsheet tool (v. 7.0.4). Note the unit cost for concrete is lower than typical as this is assumed to be non-structural grade concrete. Documentation substantiating the estimated cost of the slurry wall design and installation that was specified in the original November 2018 DRMS permit application is attached. In our opinion, the full cost for installation of the slurry wall need not be reflected in the reclamation costs subject to bonding as it will be constructed before mining operations begin. It may be appropriate to include some percentage of the total slurry wall cost in the bond, in the event the slurry wall is damaged during mining and repairs must be made. Note that the opinion of probable cost reflects the opinion of a person familiar with the industry but not an expert in this field. It reflects quantities and costs associated with a preliminary level of engineering detail. Allowances for unlisted items and contingency are intended to partly compensate for this limited knowledge. EXHIBIT S — Permanent Man -Made Structures (Rule 6.4.19): A stability analysis was completed and included in the initial application submitted in November 2018. In addition, a structure agreement was sent to all individuals or companies with structures within 200 feet of the property boundary. To do so, an 811 locate request was put out to gather all underground utility information. Above ground utilities were located on site.

The following items were discussed as needing to be updated and submitted to the Division of Reclamation Mining and Safety and are either discussed herein or attached. • Historical groundwater levels on the site are provided as an excel spreadsheet. The data was obtained from Aggregate Industries as part of the monitoring at the nearby WW Farms Pit (M-99- 098). This data provides the necessary baseline groundwater levels prior to the installation of the slurry wall and beginning of mining. • An updated color coordinated structure map, Exhibit S-2, to better show all utilities throughout the site. • The mining plans and reclamation plan maps have been updated to show that stock pile areas will not be placed on top of underground utility lines. • The preliminary adequacy review response (dated February 15, 2019) mistakenly states that a cover crop will be used; please note that use of a cover crop is optional per NRCS guidance. • For documentation, copies of the structure agreement sent to nearby structure owners and the notices sent to adjacent property owners are attached. If you have any additional questions about the provided information feel free to contact me at (303) 452- 6611 or katybilisoly@applegategroup.com.

Water Resource Advisors for the West July 22, 2019 Angela Snyder Weld County Planning Department 1555 N. 17 Ave. Greeley, CO 80631 RE: Tollgate Pit Ditch Agreement Dear Ms. Snyder: During the USR Permit pre -application meeting for the Tollgate Pit, Bucklen Services Company (Bucklen) discussed the possibility of creating a new crossing over the Storms Lake Drainage Ditch, which is an unlined canal that bisects the Tollgate Pit property. After further discussions with the Storms Lake Drainage District (SLDD) and Greeley Irrigation Company (GIC), who together operate the Storms Lake Drainage Ditch, revealed that they have substantial apprehension about installing a new culvert or bridge on the ditch within the property boundaries. The parties decided it would be best for all involved if Bucklen utilized an existing crossing over the ditch rather than construct a new one. No additional agreements are needed with either entity for Bucklen to use this existing crossing. As discussed at the pre -application meeting, Bucklen intends to seal the pit with a slurry wall prior to the commencement of mining operations. The need to convey groundwater from within the pit to the river will be significantly reduced due to this mining method. Bucklen has been in discussions with SLDD and GIC about using the ditch to convey this water to the Poudre River, but thus far have not been able to secure a contract or agreement to this effect. At this time, Bucklen plans on hauling the groundwater trapped within the sealed Tollgate Pit to the nearby Bucklen Pit and discharge it into existing settling ponds at that location which drain to the Poudre River. These settling ponds and discharge point are covered by an existing Colorado Department of Health and Environment (CDPHE) National Pollutant Discharge Eliminations System (NPDES) permit.

ITABLE OF CONTENTS General Project Information 1 Project Location 1 Property Description 1 Methodologies I Design Parameters 2 Rational Method 2 Offsite Drainage 3 Conclusion 3 APPENDICES Appendix A: Vicinity Map Appendix B: Soils Information Appendix C: NOAA Precipitation Data Appendix D: Reclamation Plan GENERAL PROJECT INFORMATION PROJECT LOCATION The Tollgate Pit site is located within the west '/2 of the southwest 'A of Section 29, Township 6 North, Range 66 West of the 6'" principal meridian in Weld County Colorado. Refer to the Vicinity Map within Appendix A for more detailed location information for the site and surrounding area. PROPERTY DESCRIPTION Tollgate Pit is proposed to be located near the city limits of Greeley and Windsor, in Weld County, Colorado. The site is at the northeast corner of O Street and 83"r Avenue. The parcel is approximately 60 acres in size, 25 acres of which will consist of the actual mined area. Other components of the site include stockpile locations, access roads, and truck parking location. The remining undisturbed acreage can be described as dry pasture maintained for private utility right of ways, offsets, and access. Within the site, there is one surface water resource, Storms Lake Drainage Ditch, overseen by the Greeley irrigation Company. The Cache La Poudre River is approximately %2 mile to the south of the parcel. The plan is to engage in dry mining throughout the site. For this to be done, a slurry wall will be installed prior to the commencement of mining and dewatering trenches will be constructed around the perimeter of the pit. Water from these trenches will be discharged in the Storms Lake Drainage Ditch. Once initial dewatering work has been done, pumping will only be required to remove collected precipitation after storm events. The site is in an area with higher terrace deposits which contain arkosic gravel and sand with some loosely cemented sand and gravel. Boring data (Appendix 13) indicates that bedrock is located at approximately 40 ft below the ground surface. Two bore holes within the site indicate the depth to groundwater as 14' and 18'. The main commodity to be mined is aggregate; the mining will last approximately 10 years depending on economic conditions. The proposed reclaimed use is for water storage and dry land pasture. Since the mining will be done at a 31-1:1 V slope, reclamation will require minimal efforts. One item which will need to be added is a side channel spillway structure due to the property being half located in the John Law Floodplain (zone A). More information on this can be found within the Division of Mining Reclamation and Safety Permit (M- 2018-060). METHODOLOGIES The focus of this drainage report is to estimate how drainage and runoff from the parcel will change due to the proposed mining plan. The parcel size is 62 acres in size, making the Rational Method a suitable method for determining pre and post -development runoff from the site. For this drainage design, LiDAR elevation data was used to confirm the parcel consisted of one drainage basin. With the particular landscape being quite flat, the overall drainage basin to that point is much larger than the parcel itself. Analysis of the LiDAR elevation data showed that all offsite drainage delivered to the parcel and all runoff from the parcel itself will be collected and discharged at the point where the Storms Lake Drainage Ditch exits the property at the southern boundary. Since the site will be changed due to the mining process, a runoff flow will be calculated for 1.) pre site conditions and 2.) post site conditions. DESIGN PARAMETERS For this drainage area, the pre -site conditions were classified as being agricultural. The runoff -coefficient was assumed to be 2% impervious based on Table 6-3 of the Urban Strom Drainage Criteria Manual Vol. 1 by Urban Drainage and Flood Control District. Lower percentages of imperviousness correspond to undeveloped areas such as green belts or agricultural areas. Soil types on the site range from loam to fine sandy loam to sandy loam, in order of highest percent of the total site to the lowest. Based on NRCS Web Soil Survey (Appendix B), the rating of the soils on site are both A (80%) and 13 (20%). Group A soils have a high infiltration rate when thoroughly wet. These consist of deep, well drained to excessively drained sands or gravelly sands. Group B soils have a moderate infiltration rate when thoroughly wet and consist of moderately deep or deep, moderately well drained or well drained soils that have moderately line texture to moderately coarse texture. Post mining, 36.6 acres of the total 62 acres will be reclaimed with native vegetation and so will remain low imperviousness with a runoff coefficient of 2%. The remaining are of the parcel will consist of a paved access road (0.43 acres) with a runoff coefficient of 100%, and the actual pit area (25 acres) which will have a runoff coefficient of 0% because all rainfall in this area will be contained within a slurry wall lined pit and so will no longer contribute to runoff. Any stormwater collected within the mined area will be pumped out in a controlled manner over the following 72 hours (as required by Colorado Water Law) at a rate that is capable of being carried by the Storms Lake Drainage Ditch without causing downstream flooding. The design storm selected for this site was the 100 -year, I -hour event. NOAA Atlas 14 Point Precipitation Frequency Estimates for the Windsor, Colorado station, show 2.83 inches for the 100 -year frequency, 1 -hour duration storm (Appendix C). The time of concentration is described as the time required for water to flow from the most remote part of the drainage area to the design point. To estimate this, the distance from northern most point to the southern most point (where the water would flow off the site) was measured to be approximately 2,400 ft. Assuming the water will flow at rate of 1 ft/s, the time of concentration would be about 40 minutes. As a more standard practice, the 1 -hour event was selected to analyze the site. RATIONAL METHOD The Rational Method is appropriate for noncomplex areas that are less than approximately 90 acres in size, according to the Urban Drainage and Flood Control District. Rational Method: Q = CIA Where Q=the peak rate of runoff (cfs) C=runofcoefficient (non -dimensional, displayed as decimal) 1=average intensity of rainfall for a duration equal to the time of concentration (inches/hour) / = 28.5Ps = 28.5'2.80 = 2.83 inches (10+Td)8.786 (10+60)0.786 where P1 = 1hour point rainfall depth (inches) Td = storm duration (minutes) A =tributary area (acres) 2 Qpre = (. 02) * (2.83) * (62) = 3.51 cfs Where Qpre is the peak runoff rate for the pre mining conditions Qpostl = (• 02) * (2.83) * (36.6) = 2.07 cfs Qpost2 = (1) * (2.83) * (0.43) = 1.22 cfs Where Qpostl is the peak runoff rate for the post mining conditions not including the asphalt access road or mined area. Where Qpostl is the peak runoff rate for the post mining conditions access road to remain. When combined, the two post mining peak flow rates equate to 3.29 cfs. Based on this analysis, it was determined that the peak flow from the site will not increase due to the proposed land use (3.29 cfs compared to 3.51 cfs). OFFSITE DRAINAGE Ofisite drainage is being routed through the parcel via the Storms lake Drainage Ditch. This will not be impacted by the proposed mining operations. S11)E CHANNEL SPILLWAY Because a portion of the site lies within the John Law Floodplain Zone A, a side channel spillway is required to collect and control floodwater at an armored location in order to protect the integrity of the excavation slopes and liner. The Reclamation Plan (Appendix D) displays the side channel spillway details. The spillway was designed in accordance with the Urban Drainage and Flood Control District Guidelines. The start of the spillway is located east of Storms Lake Drainage easement, in order to not decrease the ditch's carrying capacity CONCLUSION The proposed mining plan and resulting post -reclamation land use will not increase runoff from the Tollgate Pit site. Therefore, the proposed development project will reasonably preserve the natural character of the area and will prevent adverse effects to downstream neighbors and public rights -of -way from changes in stormwater runoff. Since the area will be dry mined, any storm water captured in the pit will be pumped out into Storms Lake Drainage at a reasonable rate. Bucklen Services Company and Storms Lake Drainage are currently working on an agreement regarding conveyance in the ditch. REFERENCES Urban Drainage and Flood Control District.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. ait Natural Resources Web Soil Survey Conservation Service National Cooperative Soil Survey 6/19/2019 Page 3 of 4 Hydrologic Soil Group —Weld County, Colorado, Southern Part Tollgate Pit Rating Options Aggregation Method: Dominant Condition Component Percent Cutoff' None Specified Tie -break Rule: Higher gun Natural Resources Web Soil Survey Conservation Service National Cooperative Soil Survey 6/19/2019 Page 4 of 4 GEOTECHNICAL BORING LOG PROJECT NAME• DATE RIVERViEW RESOURCE 2-23-06 SAM aDRS 0 5 4 9 14 19 32 11 5 (me) 10 41 69/6' 6 F 12 LOCATION: 11 ACRE QRR PROPERTY, EAST SIDE, NW Y4 OF SW rt OF SEC. 29, T6N, R66W DRILLER: DRILLING ENGINEERS, ROB ORIWNG METHOD: 4.25" ID HOLLOW STEM AUGER tA60RATCRY IB11NC RATS TWAT • BORING THW-1 fuai COORDINATES (NAD 83): PAGE OF 516309 X, 4478633 Y 1 1 CESCRFID I • ... . ., P 17.5' ..4;‘)) •• • �'•.0• ', 1 M.

Water Resource Advisors for the West July 11, 2019 Angela Snyder Weld County Planning Department 1555 N. 17 Ave. Greeley, CO 80631 RE: Tollgate Pit Flood Hazard Development Permit Dear Ms. Snyder: Bucklen Services Company (Bucklen) is proposing to mine a portion of Weld County Parcel #080529300009 for aggregate. This mining operation is known as the Tollgate Pit. The final reclamation will consist of a lined water storage area. The slurry wall will be constructed once a Weld County Use by Special Review permit is obtained and prior to any mining. The west half of the parcel is located within the John Law Floodplain, Zone A. This area has extremely limited data regarding the floodplain. To my knowledge, there are been two LOMRs completed on the John Law floodplain: 1. Report titled Final Report Pre -Disaster Mitigation Grant Evaluation for the Slough/Law Channel, by Anderson Consulting Engineers, Inc., and dated April 9, 2010. This report does include supplemental HEC-RAS modeling. The property described for this USR application lies just to the east and outside of the study area within this report. 2. Report titled John Law Ditch Colorado and Southern Railroad Flow Path Zone A Analysis, by Baker and dated August 2009. Within this report, the `East Split' refers to an area north of the property (on the north side of the railroad tracks). The analysis conducted for this report was generally qualitative and did not involve the creation of a model; instead considerable engineering judgement was exercised to determine a flow path that then connected with the floodplain of the Cache La Poudre River. The report calls out that once the flow passes under the East Split bridge, it will continue southward before being collected in a ditch approximately 1,000 feet downstream of the railroad. A discharge for the 100 -year flow in the East Split is not specifically specified, but this report uses the 100 -year discharge from where Anderson's report (referenced above) ended, in the vicinity of the Kodak Railroad Spur. o In relation to this, Weld County provided HEC-RAS modeling files which correspond to the 'East Split'. The East Split area does not necessarily cover the project location, but is limited to the sole bridge underpass that is referred to as the East Split. This model was prepared by Wohnrade Civil Engineers, Inc based on March 2017 survey of the land. The model was prepared for lots A and B of RE -4516 for property owned by the Woodland Home Company. This model uses 20% of the 100 -year discharge specified in the report described above, corresponding to a flow rate of 354 cfs. No entity, municipality or county has much information on this specific location of the John Law Floodplain. Many also feel that the floodplain may still need to be updated to better represent the area. www.applegategroup.com Denver • Glenwood Springs • Hotchkiss (303) 452-6611 RE: Tollgate Pit Flood Hazard Development Permit July 11,2019 Page 2 of 3 See Figure 1 for the floodplain in regards to the parcel and mining boundary. The outline of the current floodplain zone A becomes contained in the Storms Lake Drainage at the upstream side of O Street (WCR 64). Since the floodplain is Zone A, there are no depths or base flood elevations that could be utilized for a robust quantitative analysis. FIGURE 1. FLOODPLAIN MAP µ'ITH THE PROPERTY AND MINING LIMITS OUTLINED. On this property, temporary topsoil and overburden stockpiles (approximately 3.5 acres in size) will be kept on the property south and west of the Storms Lake Drainage Ditch, approximately represented as a star in Figure 1. These will be located on site for the duration of mining and will be needed for final reclamation on site. During mining, an excavation within the floodplain north and east of the Storms Lake Drainage Ditch will be created; this excavation may partially or fully offset the reduction in flow area resulting from the temporary stockpiles. The above assessment assumes that the stockpile area is accurately represented as being in the floodplain. We assess that the capacity of the Storms Lake Drainage Ditch upstream of O Street is similar to the capacity downstream of O Street. Given that the existing floodplain mapping for the area shows that the East Split flow will be completely contained by the Storms Lake Drainage Ditch downstream of O Street, in our engineering judgement, we expect that the Storms Lake Drainage Ditch will intercept and contain the flood flows upstream of O Street and therefore would form a boundary on the west side of the floodplain in that area, thus preventing the stockpile area from being inundated during the 100 -year flood event. In this situation, there would be no reduction in flow area from the stockpiles and the excavation east of the Storms Lake Drainage Ditch would increase the flow area, thereby reducing flood levels at this location. www.applegategroup.com Denver • Glenwood Springs • Hotchkiss (303) 452-6611 RE: Tollgate Pit Flood Hazard Development Permit July 11, 2019 Page 3 of 3 In summary, because the Zone A John Law floodplain currently lacks a detailed analysis, we performed a qualitative assessment using the limited information available in the reports referenced above. Combined with discussions with Weld County Floodplain administrators and the offset the mining excavation will cause for the stockpiles, in our opinion the proposed mining plan at the Tollgate Pit will have a no rise impact on the John Law floodplain.

In this update, the permissible noise levels are compared to the Colorado Revised Statues rather than Weld County Code. Colorado Revised Statute 25-12-102 was referenced to confirm the area is considered industrial. Noise Report Section 25-12-103 of the Colorado Revised Statues (CRS) describes the maximum permissible noise levels for an industrial area activity to be 80 dB(A) from 7:00 a.m. to 7:00 p.m. and 75 dB(A) from 7:00 p.m. to 7:00 a.m; these noise levels are measured a distance of 25 feet outside of the property line. Table 1, below, describes the maximum permissible noise levels in more detail. Within the Tollgate Pit site, peak noise levels have been estimated based on equipment type using the Federal Highway Associations' Construction Noise Handbook. Most of the peak noise levels for the different types of machines are above the 80 dB(A) maximum allowance, but all mining and noise activities will be located further away than 50 ft from the property boundary, which is distance machine peak noise level is measured based on the Federal Highway Administration. We estimate that all machinery working in the pit and stockpile activities will be located at least 75 feet from the property boundary. Note this does not include haul roads as those enter and exit the property line. Additionally, no equipment will be regularly running during the 7:00 p.m. to next 7:00 a.m. timeframe. TABLE 1.

For mitigation, dirt berms will be placed in areas deemed most sustainable or effected by high noise levels (i.e. residential property). As mining continues and the pit descends, the amount of noise disturbance will decrease to the surrounding properties. There will be no constant stationary noise www.applegategroup.com Denver • Glenwood Springs • Hotchkiss (303) 452-6611 RE: Noise Report - Weld County USR Application Tollgate Pit (PRE19-0120) September 3, 2019 Page 2 of 2 from items like pumps (after initial dewatering), crushing, or screening.

Inc Tollgate Pit Traffic Impact Study BucKlen Services Weld County. Colorado July 24, 2019 Tollgate Pit Traffic Impact Study 1.0 Introduction Bucklen Services is proposing to develop the Tollgate Pit on the northeast corner of 83rd Avenue / O Street in Weld County. The location of the pit is shown in Figure 1 and the site plan contained in Figure 2 shows the site access on O Street approximately 1.160' east of 83'6 Avenue. The study has been prepared based on the Weld County traffic impact study requirements'. 2.0 Study Assumptions The following assumptions were utilized for this study. • Short -Term Study Horizon. The pit is expected to be operational in the Year 2020, therefore, the short-term horizon is Year 2020. • Long -Term Study Horizon. The Year 2040 will be the long-term horizon which coincides with the Year 2040 volumes that were provided by the North Front Range MPO. This information is contained in Appendix A. • Growth in Background Traffic. Traffic volumes on O Street are expected to grow at 1.4% annually based on information that was provided by the North Front Range MPO. • Future Improvements to the Study Area Intersections. 0 Street is classified as a four -lane major arterial in the Greeley 2035 Comprehensive Transportation Plan2. The corridor currently has two through lanes, so an expansion to four lanes was assumed for the Year 2040 traffic volume scenarios. • Saturation Flow Rate. The saturation flow rate was assumed to be 1,900 passenger cars / hour / lane which is typical in urban areas. • Peak Hour Factor. A peak hour factor of 0.85 was assumed for all movements in all of the scenarios. • Truck Percentage. Based on the data collected for the study, the through movements on O Street were assumed to have 10% trucks. For the movements in and out of the pit, a truck percentage of 95% was assumed. These percentages assume that trucks have three or more axles. 2 Weld County Engineering and Construction Criteria. Weld County. April 2012. Greeley 2035 Comprehensive Transportation Plan. City of Greeley. Adopted May 3, 2011 Sustainable Traffic Solutions, Inc. 1 Tollgate Pit Traffic Impact Study Bucklen Services Weld County Colorado July 24 2019 3.0 Existing Traffic Volumes Traffic count data for the study were collected on Wednesday June 5th, 2019 by All Traffic Data. The existing and future daily volumes are summarized in Table 1. The count data are contained in Appendix B. 4.0 Site Generated Traffic Volumes 4.1 Trip Generation Quarries are not a land use that is addressed in the ITE Trip Generation manual', therefore. the trip generation was determined based on information that was provided by Bucklen Services. The truck and passenger vehicle traffic are summarized in Table 2. When the quarry is fully operational, the daily traffic volumes are expected to include 34 truck trips and 10 passenger vehicle and light duty pickup trips. 4.2 Trip Distribution and Assignment The trip distribution that is contained in Figure 3 is based on information that was provided by Bucklen Services. 5.0 Future Traffic Volumes Background traffic volumes (without the development traffic) were estimated by inflating the existing volumes for the traffic on O Street using the growth rate that is documented in Section 2.0. Table 1 contains the Year 2020 and Year 2040 background traffic volumes. The projected peak hour volumes at the completion of the project were estimated by adding the traffic that is expected to be generated by the Tollgate Pit to the background traffic volumes (see Table 1). 6.0 Auxiliary Lanes STS reviewed the need for auxiliary lanes at the access to the pit using the Year 2020 total traffic volumes scenario. Weld County has criteria for auxiliary lanes that are contained in Section 6.6 of the Weld County Engineering and Construction Criteria. The following thresholds trigger the need for the construction of auxiliary lanes on arterial and collector roadways. • Left Turn Deceleration Lane. A left deceleration lane with storage length plus taper length is required for any access with a projected peak hour left ingress turning volume greater than 10 vph. The projected peak hour volumes are below the threshold, therefore, a left turn deceleration lane is not required. • Right Turn Deceleration Lane. A right deceleration lane with storage length plus taper length is required for any access with a projected peak hour right ingress turning volume greater than 25 vph. The projected peak hour volumes are below the threshold, therefore, a right turn deceleration lane is not required. Trip Generation, 10"' Edition. Institute of Transportation Engineers. September 2017 Sustainable Traffic Solutions, Inc. 2 Tollgate Pit Traffic Impact Study Bucklen Services Weld County, Colorado July 24, 2019 • Right Turn Acceleration Lane. A right turn acceleration lane with taper is required for any access with a projected peak hour right turning volume greater than 50 vph and a single through lane in the direction of the right turn. The projected peak hour volumes are below the threshold, therefore, a right turn acceleration lane is not required. • Left Turn Acceleration Lane. A left turn acceleration lane with transition taper may be required if it would benefit the safety and operation of the roadway. A left turn acceleration lane is generally not required when the acceleration lane would interfere with the left turn ingress movements to any other access. Considering the low traffic volumes on 0 Street, there are ample gaps in traffic and a left turn acceleration lane is not necessary. 7.0 Level of Service Analysis To evaluate the performance of the study area intersections, the level of service (LOS) was calculated using VISTRO software. This software package utilizes criteria described in the Highway Capacity Manual4. LOS is a measure used to describe operational conditions at an intersection. LOS categories ranging from A to F are assigned based on the predicted delay in seconds per vehicle for the intersection as a whole, as well as for individual turning movements. LOS A indicates very good operations, and LOS F indicates poor. congested operations. Acceptable intersection operation in urban areas is typically considered LOS D or better. Three peak hours were analyzed including the morning peak hour, a midday peak hour, and the evening peak hour. The analysis shows that the intersection is expected to operate at LOS A during the morning and evening peak hours, and operate at LOS B during the midday peak hour. The level of service for stop controlled intersections is based on the lowest letter grade for the side street movements. Figure 4 contains the laneage and traffic control that were assumed for the Year 202O and Figure 5 contains the laneage and traffic control that were assumed for the Year 2040. Table 3 summarizes the operational analysis and the VISTRO output is contained in Appendix C. 8.0 Conclusions STS has drawn the following conclusions based on the analysis performed in the study. • Auxiliary Lanes. The traffic volumes entering and exiting the Tollgate Pit are expected to be low enough that a left turn deceleration lane, right turn deceleration lane, and a right turn acceleration lane will not be required by Weld County criteria. A left turn acceleration lane will not be necessary due to the low traffic volumes on O Street. n Intersection Operation. The site access is expected to operate at LOS A and LOS B during all of the traffic volume scenarios, therefore, the 4 Highway Capacity Manual, 6' Edition. Transportation Research Board 2016.

Please provide Year 2040 daily volumes and the base year volumes for all legs of that intersection. I've attached count data for the east leg of the intersection for your reference. I noted on the website that you are the Executive Director. I prepare lots of traffic impact studies and used to make similar requests of DRCOG on a weekly basis as I'm sure that other consultants did. DRCOG finally published their Year 2015 data and Year 2040 projected volumes and life is much simpler now. Maybe this is something that the NFRMPO would consider. Joseph L.

Inc. _TMOS energy Tollgate Pit Mining Impact Feb. 1, 2019 Atmos Energy has reviewed the information it has been provided regarding the Tollage Pit proposed by the Applegate Group. After reviewing where our utility facilities are located a conversation with Mr. Dains at Applegate was held over the phone. It was relayed to Atmos Energy that the Tollgate Pit will be a gravel pit style operation and that there will be no blasting involved. Atmos Energy believes that there will be no negative impact on its existing facilities, from the Tollgate Pit. Respectfully, tet; Eric Boutwell, P.E.
