I Lessee). The following provisions are part of this Oil and Gas Lease and, if there be conflict or inconsistency between these provisions and any of the foregoing provisions, then the following provisions shall apply and take precedence: 1. Notwithstanding anything to the contrary in the printed lease form to which this Addendum is attached, the terms of this Addendum shall be considered part of the Lease, and to the extent of any inconsistency between the provisions of this Addendum and the printed form provisions of this Lease, the terms of this Addendum shall control for all purposes. 2. This Lease is made and accepted WITHOUT ANY COVENANT OR WARRANTY OF TITLE OF ANY KIND, EITHER EXPRESS OR IMPLIED. If Lessor owns an interest in the Leased Premises less than the entire fee simple mineral estate, then shut-in royalties and royalties to be paid Lessor shall be reduced proportionately, but no portion of the bonus payments made by Lessee to Lessor in consideration for executing this Lease shall be refundable or collectible by Lessee. Lessee acknowledges that it has done its own due diligence and title investigation and that the bonus payment made by Lessee to Lessor for executing the Lease is final and non - revocable. 3. Lessor specifically excludes and reserves from this Lease all uranium, coal, rights to coal, and any other minerals in and under the leased premises that are not covered by the Lease, together with the right to explore for and produce such other minerals. 4. For the purposes of this Lease, "unitization" or "unitize" refers to the consolidation of separately owned mineral or leasehold interests in oil or gas covering a common source of supply for the joint operation of such interests as a single unit (often covering a relatively large area that may range from 10,000 to 20,000 acres but which may be larger or smaller), in which the interests committed to the unit are subject to a Federal or State unit agreement governing the development of the unit area and the allocation of production revenues therefrom. "Pooling" means the combination of several small tracts of land to meet the spacing requirements permitted or prescribed for a well or wells. 5. Lessee's right and power to pool and unitize the interests granted by this Lease shall not give it the right and power to pool or unitize the mineral estate separately from the Lease or longer than this Lease is in effect as to such unitized or pooled lands. Any pooling or unitization of all or a portion of the Leased Premises shall only commit such Leased Premises to a pooled unit or unit agreement while this Lease is in effect as to such lands. If any portion of the Leased Premises is released or terminated, the underlying mineral estate as to such portion shall no longer be committed to any unit agreement or pooled unit, 6. If a unitized area is created which includes all or a portion of the Leased Lands, then production from the unitized area shall maintain this Lease only as to that portion of the Lease Premises included within a unitized area and committed to the unit agreement. If only a portion of the Leased is included in a unitized area and committed to the terms of a unit agreement, or if the unitized area contracts under the terms of such unit agreement so that a portion of the Leased Premises later falls outside the unitized area, this Lease shall be deemed segregated as to the portion committed and the portion not committed to the unit agreement, and the provisions of the Lease shall apply separately to such segregated portion. 7. If a pooled area is established, either by government authority (compulsory pooled units) or by voluntary action, production from the pooled area shall maintain this Lease only as to that portion of the Leased Premises included within the pooled area. Lessee may not pool any portion of the Leased Premises with any other lands, leases or interests located more than two miles from the boundary of the Leased Premises included in the pooled area without Lessor's prior written consent. In order for pooling to be effective, Lesseeshall execute in writing and place of public record in the county or counties in which the pooled acreage is located an instrument or instruments identifying and describing the pooled acreage. Lessee shall promptly furnish to Lessor a copy of the document pooling the acreage. If a well is drilled on a portion of the leased premises that is non -unitized and is also not part of a pooled unit, such a well shall be deemed to be on a pooled unit that conforms to the spacing acreage for that well, or if not spaced, shall be deemed to be a pooled unit containing 320 acres for a gas well and 40 acres for an oil well, and production from such a well shall only be deemed to hold the Lease as to such acreage. 8. Upon the expiration of the Primary Term, this Lease shall terminate and expire as to all rights one hundred feet (100') below the base of the deepest formation then producing in any well drilled on the leased premises, or lands pooled and unitized therewith, unless Lessee is then engaged in drilling, reworking or completion operations on any lands still covered by this Lease, or lands pooled and unitized therewith (as to any zone or formation) and so long thereafter as Lessee continues such operations on the Leased Premises or lands pooled or unitized therewith with no cessation of more than one hundred eighty (180) consecutive days between the completion or abandonment of such operations on one well and the commencement of actual drilling, reworking, or completion operations on the next well. Similarly, during the secondary term of the Lease, if a well on the I.. -eased Premises, or lands pooled 4340330 09/29/2017 03:07 PM Page 4 of 4 and unitized therewith thereafter ceases to produce oil or gas in commercial quantities from any zone or formation, this Lease shall expire as to all rights 100 feet below the base of the deepest formation then producing from any well drilled on the leased premises, or lands pooled or unitized therewith, unless Lessee is then engaged in drilling, reworking or completion operations on any lands still covered by this Lease as to any zone or formation and so long thereafter as Lessee continues such operations on the Leased Premises or lands pooled or unitized therewith with no cessation of more than one hundred eighty (1 80) consecutive days between the completion or abandonment of such operations on one well and the commencement of actual drilling, reworking, or completion operations on the next well, 9. Provisions in the Lease referring to the commencement of drilling operations for a well, or the commencement of reworking operations for a well, shall mean the commencement of actual drilling or reworking operations. Actual drilling operations shall be deemed to commence at such time as Lessee has a drilling rig on location and actual drilling has begun (i.e. the drill bit has penetrated the surface). Actual reworking operations shall be deemed to commence when the reworking or completion rig is physically on site_ Lessee shall continue and complete drilling operations and all other operations, once commenced, with reasonable diligence. Drilling, completion or reworking operations shall be deemed to have ceased when the drilling, completion or reworking rig is released from the well location. 10. For each tract of leased land or leased formation which is terminated under the Lease, Lessee shall be obligated to record in the county records a release of this Lease insofar as it covers such nonproducing lands or formations within 60 days following the date this Lease terminates as to that tract of land or formation_ Ail such releases shall be made free of encumbrances created by or under Lessee and Lessee shall provide Lessor a copy of the recorded release upon filing. 11. The Lease shall not be extended more than a cumulative total of 48 -twenty four (24) months by payment of shut-in royalties. The shut-in royalty shall be $10.00 per acre per year. Such shut in royalty payment shall be made within one hundred twenty (120) days from the date of the shut in of the well or wells resulting in the cessation of production and sales from the Leased Premises or lands pooled or unitized therewith. In addition to the twenty four (24) month cumulative total limit, the payment of shut-in royalties shall not be deemed to constitute constructive production unless actual production and sales are reestablished within 12 consecutive months from the date of any cessation of sales of production from the Leased Premises or lands pooled or unitized therewith. 12. Lessee shall be responsible for all damages or injury caused by its (including agents, contractors, invitees and employees) use of the Leased Premises. Lessee hereby agrees to and shall indemnify, defend and hold Lessor and its successors and assigns harmless from and against any and all loss, liens, claims, liabilities, causes of action, expenses, judgments, damages or any obligations of any kind whatsoever, including reasonable attorneys' fees, incurred by any person or entity for injury to or death of any person or damage to any property, or incurred by or threatened against Lessor arising out of, resulting from or in connection with the use of and operations on the Leased Premises by Lessee (including its contractors, agents, employees and invitees). Lessee specifically accepts responsibility and liability for any pollution, contamination or toxic damages caused by its operations on or near the Leased Premises or acreage pooled therewith. Should the Lease or any portion thereof, terminate for any reason, Lessee shall remain responsible for all accrued liability resulting from operations of Lessee hereunder. 13. If Lessor files a legal action to enforce any express or implied obligation of this Lease and receives a favorable judgment from a court of competent jurisdiction, then Lessee shall reimburse Lessor for all costs of such legal proceeding and reasonable attorney's fees. 14. Upon Lessors' request, Lessee, at no expense to Lessor, shall deliver to Lessor a copy, without warranty as to the accuracy coverage or application, of all title opinions and landman title memorandums and reports covering all or any portion of the Leased Premises or lands pooled therewith, which may be redacted as to all information regarding interests not owned by Lessor. In any provided title opinion, the Lessee will not redact the interests owned by other parties for purposes of showing the calculation of the royalty due to the Lessor, but will be entitled to redact the identities of those owners.

LAMP RYNEARSON March 26, 2021 Weld County Planning 1555 N. 17th Avenue Greeley, Colorado 80631 RE: Planning Questionnaire Mallard Exploration Field Office PLANNING QUESTIONS: 1. Explain the proposed use and business name. 4715 Innovation Dr., Ste. 100 Fort Collins, CO 80525 [P] 970.226.0342 [Fl 970.226.0879 LampRynearson.com The proposed use of the property will be a field office for Mallard Exploration with an office/shop building, outdoor storage yard, and drive aisle and parking. The field office will contain offices, cubicles, a conference room, a breakroom, and restrooms. At the north end, there will be a pull through garage/show. Mallard Exploration recently purchased the proposed property, which is the entire half section. The property will be split into two parcels; a 35.00 acre parcel and the remaining rest of the section. The property will be split by an exemption plat at the conclusion of this USR process. The field office will be located on the 35 acre parcel. Hence, all documentation will refer to this 35 acre portion of the property. 2. Explain the need for the proposed use. Mallard exploration has multiple oil and gas sites throughout Weld County and requires a common location for field workers to work from, as well as a place to store equipment. It is anticipated field workers will stop by the field office for a couple hours each shift on their way to or from the job site. Supervisors, foreman, and EHS employees would utilize the field office as a normal office setting. 3. Describe the current and previous use of the land. The land is currently and has previously been undeveloped with natural vegetation. There is an existing livestock well in the middle of the existing +/-323 acres suggesting the property was once used as rangeland. 4. Describe the proximity of the proposed use to residences. The nearest residences to the proposed site are over 8,000 ft to the northeast along WCR 98 and approximately 10,000 ft to the northwest along WCR 96. 5. Describe the surrounding land uses of the site and how the proposed use is compatible with them. The surrounding land use is mostly zoned agricultural with oil and gas operations scattered around the neighboring properties. With the proposed use of a field office and storage yard for oil and gas operations, the proposed development will be very compatible with the surrounding land uses. Omaha Fort Collins Lakewood Kansas City 6. Describe the hours and days of operation (i.e. Monday thru Friday 8:00 a.m. to 5:00 p.m.). Field employees, such as Well Operators, work in day and night shifts; therefore, employees could visit the office 24 hours a day, 7 days a week. It should be noted that field employees typically do not work a full 8 hours in the office, but rather come and go during their shift. It is estimated they will be in the office approximately 2 hours per shift. It is estimated that Supervisors, Foreman, and Environmental/ Health/Safety (EHS) employees would be in the office about 6 hours per day. A Foreman will be in the office 7 days a week, while Supervisors and EHS employees are anticipated in the office on weekdays only. 7. Describe the number of employees including full-time, part-time and contractors. If shift work is proposed, detail number of employees, schedule and duration of shifts. Initially, Mallard estimates that there will be 7 full time employees at the field office throughout the day across both day and night shifts. As Mallard continues to grow, there may be up to 15 full time employees working at this site at once in the next 5 years. At this time, there will be one employee working the night shift, with potentially 2-3 in the future. 8. Describe the maximum number of users, patrons, members, buyers or other visitors that the site will accommodate at any one time. The site will typically not have any visitors. The site may accommodate the occasional delivery truck (possibly once a day) and contractor or vendor. It is estimated that there will be up to 2 visitors per day. 9. List the types and maximum number of animals to be on the site at any one time (for dairies, livestock confinement operations, kennels, etc.). There are no plans for any animals onsite at this time. 10. List the types and number of operating and processing equipment. In addition to the proposed office/shop building the following items are proposed to be stored within the storage yard: • Up to 10 Gonex Containers to securely store tools, parts, and equipment • Diesel fuel tank • Two propane tanks • Surplus oil and gas facility equipment for use on future locations • Temporary staging of a drilling rig or storage of rig related equipment • Surplus drilling pipe Near the office building a back up generator and a communication tower will be installed. The back up generator would be used to power the office in the event of a loss of electrical service. The communication tower will be used to link Mallard's oil and gas facilities, which are automated for remote monitoring and operations, to the office. 11. List the types, number and uses of the existing and proposed structures. There are no existing structures currently on site. There will be one proposed field office, approximately 5,000 sq. ft. The field office will have offices, a conference room, cubicle workspaces, a kitchen, restrooms, and a pull through shop/garage area. 12. Describe the size of any stockpile, storage or waste areas. The site will have a 10 acre (approximately 400' x 1,100'), gravel or road base storage yard used to store non- hazardous materials, machinery and equipment. There are no planned stockpile or waste areas. 13. Describe the method and time schedule of removal or disposal of debris, junk and other wastes associated with the proposed use. Other than a typical weekly trash removal service, Mallard does not anticipate any other scheduled removal of junk or wastes. 14. Include a time -table showing the periods of time required for the construction of the operation. Below is the estimated timeframe for the construction of the proposed development: February - June: Building/Utility Design June -August: Permits and Buy Out September: Site Work and Structural October -November: Building Fit Out and Close Out End of November: Occupancy 15. Describe the proposed and existing lot surface type and the square footage of each type (i.e. asphalt, gravel, landscaping, dirt grass, buildings. There are no existing surfaces, only native vegetation on the existing property. There will be 10 acres of gravel for the storage yard, 5,000 sq ft. of building, 0.70 acres of gravel access road, 1.37 acres of gravel parking lot/building access, and 0.23 acres of concrete apron surrounding the building. The remaining acreage will be naturally seeded vegetation. 16. How many parking spaces are proposed? How many handicap -accessible parking spaces are proposed? There are 18 proposed parking stalls total. One will be a handicap -accessible parking stall with an access aisle stall next to it. With the anticipated employee/visitor count, there will be more than enough parking. 17. Describe the existing and proposed fencing and screening for the site including all parking and outdoor storage areas. There is an existing wooden fencing on site that surrounds the north, south, and east portions of the site. A proposed 6' chain link fence is proposed along the entire frontage of WCR 103 as well as along the north, west, and south edge of the property. Approximately 3,900' of fencing is proposed to encompass the entire site. The existing fence will be removed where new fencing will be installed. Due to the building and parking being setback nearly 1,000' west of the property line, no screening other than the exterior fence is proposed. The fencing along WCR 103 is located 30' west of the ROW to provide adequate distance between the fence and the road. 18. Describe the existing and proposed landscaping for the site. The existing landscaping consists of native vegetation. There is no proposed landscaping proposed at this time. Due to the building and parking being setback nearly 1,000' west of the property line, there is no landscaping being proposed. The distance, as well as the chain link fence, will provide the necessary screening from the public ROW. Additionally, due to the commercial exempt water well regulations, the well cannot be used for exterior water such as irrigation. 19. Describe reclamation procedures to be employed as stages of the operation are phased out or upon cessation of the Use by Special Review activity. The field office and storage yard proposed are permanent facilities and will not need to undergo any sort of reclamation procedure. 20. Describe the proposed fire protection measures. The proposed building will have fire sprinklers. Due to well restrictions, a water storage tank and pump will be proposed for fire protection measures. The fire suppression team/mechanical engineer will be designing the system to conservatively serve the building. 21. Explain how this proposal is consistent with the Weld County Comprehensive Plan per Chapter 22 of the Weld County Code. The proposed Mallard Field office is consistent with the Weld County Comprehensive Plan by limiting the density and intensity of development to maintain agricultural areas, respecting agricultural practices regarding water resources by maintaining minimal water usage, and by harmonizing development with the surrounding land uses by only developing a portion of the half section and providing a development that will help minimize travel distances between the Mallard Field Office and Mallard oil and gas pads. 22. Explain how this proposal is consistent with the intent of the zone district which it is located. (Intent statements can be found at the beginning of each zone district in Article III of Chapter 23 of the Weld County Code.) This proposal is consistent with the intent of the A (Agricultural) Zone District by providing areas that promote natural resource extraction and energy development within the County. Additionally, this proposal leaves open large portions of undeveloped land that can be used to conduct agricultural activities and actives related to agricultural production. 23. Explain how this proposal will be compatible with future development of the surrounding area or adopted master plans of affected municipalities. Weld County's Comprehensive Plan Map delineates the proposed property and its surrounding neighbors as "rural." As a field office for an oil and gas exploration and production company, facilities promoting energy development will be very compatible with future development of neighboring properties in the agricultural zoning. 24. Explain how this proposal impacts the protection of the health, safety and welfare of the inhabitants of the neighborhood and the County. This proposal maintains as much of the existing landscape as possible. By utilizing a field office in a central location to Mallard's oil and gas facilities, daily travel distance will be decreased, reducing emissions and road usage. A proposed detention pond will reduce 100 -year stormwater runoff to historic 10 -year release rates, greatly decreasing the amount of runoff for downstream infrastructure. In addition to reducing runoff, the pond will provide water quality, reducing any sediment or pollutants that would be in the runoff. 25. Describe any irrigation features. If the proposed use is to be located in the A (Agricultural) Zone District, explain your efforts to conserve prime agricultural land in the locational decision for the proposed use. There will be no proposed irrigation features. The proposed location only uses 35 acres of the entire half section, leaving plenty of acreage for future agricultural land. 26. Explain how this proposal complies with Article V and Article XI of Chapter 23 if the proposal is located within any Overlay Zoning District (Airport, Geologic Hazard, or Historic Townsites Overlay Districts) or a Special Flood Hazard Area identified by maps officially adopted by the County. The proposal is not within any Overlay Zoning Districts. 27. Detail known State or Federal permits required for your proposed use(s) and the status of each permit. Provide a copy of any application or permit. Water Well Permit - A Commercial Exempt water well permit has been submitted to the Colorado Division of Water Resources and is pending review. The submitted application is submitted with this USR application. Please feel free to contact me at 970-226-0342 or via email at michael.palizzi@lamprynearson.com. Sincerely, Michael Palizzi, PE Project Manager Lamp Rynearson Mallard Exploration Field Office Weld County Case #USR21-0009 Communication Tower Mallard Exploration is planning to install a communications tower at their proposed Field Office location to transmit data from Mallard oil and gas locations to the Field Office. The communications tower will be 45' high or less, and will be mounted on the side, or on top of the Field Office building (45' including the height of the building). The tower will be mounted on the west side of the building (furthest from WCR 103) in a safe location to contain ice fall and debris from tower failure, with more than a 1:1 fall zone. The tower height is being proposed so it will not constitute a hazard to aircraft. Due to the ongoing design of the Field Office building, the communications tower is anticipated to be located approximately 1,140' from the east property line and 200' from the southern property line. However, this location is subject to change slightly as the design progresses. The communication tower and appurtenant parts will comply with the minimum setbacks cited in Weld County Code Ordinance 2015-8 for the Agricultural Zone. Mallard Exploration understands the noise level must adhere to the maximum permissible noise level in the Agricultural Zone.

Describe the access location and applicable use types (i.e., agricultural, residential, commercial/industrial and/or oil and gas) of all existing and proposed accesses to the parcel. Include the approximate distance each access is (or will be if proposed) from an intersecting county road. State that no existing access is present or that no new access is proposed, if applicable. The site has an existing access at the far southeast corner of the site. This access is a 10' dirt road that will be abandoned. The proposed access' centerline is approximately 200' north of the southern property line, and about 300' north of the existing access' centerline on the property to the south. The proposed access is a 24' gravel/road base road, with 75' radii that tie into the WCR 103 roadway. A ROW permit will be applied for prior to construction of the proposed access road. The access use type will be commercial, used to access both the field office and the storage yard. 2. Describe any anticipated changes to an existing access, if applicable. The existing dirt access road will be abandoned with the construction of the proposed access road. All traffic will route through the new proposed access. 3. Describe in detail any existing or proposed access gate including its location. The existing access gate located at the property line along WCR 103 will be abandoned along with the existing access road. There will be a proposed access gate, set back approximately 30' west of the ROW On line with the proposed fence around the site). The proposed gate will have an electronic key pad, with capabilities of opening the gate from the office itself for any deliveries or visitors. 4. Describe the location of all existing accesses on adjacent parcels and on parcels located on the opposite side of the road. Include the approximate distance each access is from an intersecting county road. There is an existing 15' gravel access road on the property directly south of the proposed location. The existing access' centerline is approximately 300' south of the proposed access' centerline. The edge of the proposed Omaha Fort Collins Lakewood Kansas City south radius to the edge of the existing north radius is 180'. There are no existing accesses on the properties on the east side of WCR 103. The nearest parallel road is WCR 96 to the north, just short of a mile away. 5. Describe any difficulties seeing oncoming traffic from an existing access and any anticipated difficulties seeing oncoming traffic from a proposed access. There will be no difficulties seeing oncoming traffic from the proposed access. There is no existing vegetation or visual screening currently, and there will be no additional landscaping proposed. The proposed fence is 30' west of the ROW, so the fence will not get in the way either. 6. Describe any horizontal curve (using terms like mild curve, sharp curve, reverse curve, etc.) in the vicinity of an existing or proposed access. There are no horizontal curves in the vicinity of the proposed access. 7. Describe the topography (using terms like flat, slight hills, steep hills, etc.) of the road in the vicinity of an existing or proposed access. WCR 103 is very flat, with slopes less than 0.5% where the proposed access road is tying in to. Please feel free to contact me at 970-226-0342 or via email at michael.palizzi@lamprynearson.com.

Expected travel distribution is estimated to be 50% of traffic will come from the north on WCR 103 & 50% of traffic will come from the south on WCR 103. Mallard has oil and gas facilities located to the north and south of the proposed site, so the Field Office location is a central location for their facilities. Describe the time of day that you expect the highest traffic volumes. Omaha Fort Collins Lakewood Kansas City Traffic will likely be evenly distributed throughout the day as there will be both day shift and night shift employees. It should be noted that field employees typically do not work a full 8 hours in the office, but rather come and go during their shift. It is estimated they will be in the office approximately 2 hours per shift. It is estimated that Supervisors, Foreman, and Environmental/ Health/Safety (EHS) employees would be in the office about 6 hours per day. A Foreman will be in the office 7 days a week, while Supervisors and EHS employees are anticipated in the office on weekdays only.

General Location & Description This preliminary drainage report contains details for the overall drainage design for the Mallard field office site The report also includes information on the historic drainage patterns for the site Final drainage design information for the proposed site considers the developed site draining to a proposed detention pond located in the southeast corner of the site Flows will be captured and released into an existing road site ditch 1. Location The proposed Mallard Exploration field office site is located in the Southeast % of Section 9, Township 8 South, Range 60 West of the 6th P M within Weld County, Colorado More specifically, the site is located directly next to County Road 103, approximately 3/4 -of a mile South of County road 96 and approximately 2 miles North of Highway 14 It is approximately 2 3 miles Southwest of the abandoned town of Keota located on the prairie in the Pawnee National Grasslands or 2 3 miles Southwest of the intersection of County Road 390 & County Road 103 The proposed site is 35 acres The existing property is the entire south half of section, however, Mallard Exploration is currently in the process of creating a 35 acres parcel through exemption deed for the Field Office site The east 20 acres of the site will be developed for the office, and the remaining acreage to the west will remain undeveloped The property is currently undeveloped and consists of moderately dense weeds and native grasses In general, drainage from the site travels overland towards an existing swale along County Road 103 to the southeast Existing slopes on the site range from 0 to 1% According to the NRCS website, the site consists of predominantly Type B and C soils The Type B soils are classified as Stoneham fine sandy loam The Type -C soils are classified as Platner loam See Appendix B for soils data The proposed project is a field office for Mallard Exploration The proposed protect will be maintained by Mallard Exploration and will utilize undeveloped land for their field and storage yard The proposed site will consist of a 5,000 square foot building, parking, access roads, gravel storage yard and a detention pond The runoff from the site flows to the proposed detention pond in the southeast corner of the site before discharging offsite into historical paths B. HISTORIC DRAINAGE 1. Basin Description The site is not located within in any Major Drainage Basin Historically, drainage from the site Lamp Rynearson, Inc Preliminary Drainage Report for Mallard Exploration Field Office Project No 0220014 01 March 2021 Page 1 meanders overland in a southeasterly direction to a drainage swale parallel to County Road 103 There doesn't appear to be a defined drainage way where storm water collects and flows to the drainage swale along County Road 103 According to the Flood Insurance Rate Map (FIRM) Map No 08123C1075E with an effective date of March 5, 2007, the proposed development is located completely outside any flood hazard areas (see Appendix B) 2. Existing Description The historic runoff from the project area flows northeasterly to an existing drainage swale along County Road 103, and ultimately south where it continues along the drainage swale Historic basins were delineated considering existing and expected future runoff discharge locations from the project site The detention basin outlet pipe is designed to outfall to the same existing natural channel mimicking historic conditions See below for a summary of existing property basin flows Table 1 — Rational Method Calculations — Existing Conditions EXISTING BASIN CALCULATIONS DESIGN POINT BASIN AREA Imperviousness % tc C10 C100 Q10 Q100 El El 19 44, 2 0% 33 3 0 26 0 51 11 57 37 14 E2 E2 15 56" 2 0% 47 8 0 26 0 51 7 38 23 70 TOTAL 35 00 2 0% NA NA NA 18 95 60 84 C. DESIGN CRITERIA 1. Hydrologic Criteria Data within the Weld County Charter and County Code Storm Drainage Cntena and Weld County Engineenng & Construction Cntena Manual for the Mallard Exploration Field Office, located in weld County, was used for specific rainfall data for the 2, 5, 10, 25, 50 and 100 -year storms of 0 86, 1 35, 1 54, 2 16, and 2 55 respectively (see Appendix B) Rainfall data of New Raymer was used to represent the Mallard Exploration Field office site due to their close proximity to each other Since the basins are less than 160 acres, the Rational Method was used to calculate developed stormwater runoff Composite impervious values for each basin were calculated based on site layout Runoff coefficient "C" values were taken from Table RO- 5 of Weld County's Drainage Criteria Manual (V 1) Runoff values were calculated using the Rational Method (see Weld County reference information provided in Appendix B) The imperviousness is determined based on -site layout with the imperviousness values obtained from Table RO-5 of Weld County Drainage Criteria Manual (V 1) The runoff coefficients corresponding to weighted average basin imperviousness and hydrologic soil groups were calculated using UD-Rational V2 00 spreadsheet that was created by Mile High Flood District and is in accordance with Weld County's Drainage Criteria Manual (V 1) The detention basin and outlet structure has been designed to capture and convey the Water Quality Capture Volume (WQCV), 10 -year, and the 100-yr Volume as outlined by the SDDTC Lamp Rynearson, Inc Preliminary Drainage Report for Mallard Exploration Field Office Project No 0220014 01 March 2021 Page 2 2. Hydraulic Criteria Stormwater will be captured and detained once the site is developed Hydraulic structures and conveyances were designed using techniques developed or adopted by Weld County Charter & Code Chapter 8, articles I - XVI of the Weld County Charter & Code were referenced and are consistent with standard calculation methods typically used for similar developments Water Quality Capture Volume (WQCV) designs were done using the Mile -High Flood District's (MHFD) UD-Detention v4 04 spreadsheet program The results of the detailed calculations are provided in Appendix C The detention pond will be sized to store the stormwater runoff generated by the 1 -hour, 100 - year storm falling on the developed site and release of the detained water at the historic runoff rate of the 1 -hour, 10 -year storm falling on the undeveloped site for non -urbanizing areas The detention pond will include volume for the WQCV This WQCV will be included as a portion of the total 100 -year detention pond volume The water quality capture volume will be set to drain at 40 hours The elevation of the top of the detention pond embankment, except at the spillway, will have a minimum of 1 -foot freeboard above the 100 -year water surface elevation in the detention pond The outlet pipe of the pond will contain a minimum of two concrete cutoff walls embedded at a minimum of 18 inches into the undisturbed soil The cutoff walls will be minimum of 8 inches thick The outlet pipe bedding material will consist of native earthen soil to the daylight point The detention pond will contain an emergency spillway capable of conveying the two times the peak 100 -year storm discharge The invert of the emergency spillway will be equal to, or above, the 100 -year water surface elevation The depth of the flow of the emergency spillway will be 6 inches or less The spillway will have effective erosion protection In order to protect the emergency spillway from catastrophic erosion failure, buried nprap shall be placed from the emergency spillway downhill to the embankment toe of slope and covered with 6 inches of topsoil The nprap will be sized at the time of final engineering design D. DRAINAGE FACILITY DESIGN 1. General Concept The existing conditions have been divided into 2 basins A small ridge in the middle of the site separates the 2 basins The proposed site has been divided into 3 basins, with 2 on site basins and one offsite basin One detention pond is proposed along the southwesterly corner of the site Due to the layout of the site and existing slopes 2 swales were designed One to capture water along the west and south of the property and the other in the other next to the access road to capture water coming off the storage yard Both of these swales will be routed east into the pond The overflow spillway has been sized to allow twice the 100 -year flow to be released at incoming rates The goal of the proposed drainage design is to capture the water_ quality volume in the pond and release at rates that allow for minimum 40 -hour drain time for the WQCV A hydraulic analysis was completed based on calculated discharges to determine the sizes of the proposed drainage structures Detailed design of hydraulic structures, including the detention pond outlet structures, culverts and swales, has been provided in Appendix C Lamp Rynearson, Inc Preliminary Drainage Report for Mallard Exploration Field Office Project No 0220014 01 March 2021 Page 3 2. Specific Details The following paragraphs outline the calculated runoff for each sub -basin, a description of the basin characteristics and drainage patterns has been provided Basins B1: Basin B1 (20 99 acres) makes up the east half of the site the contains the entire portion that will be developed This basin contains a gravel storage yard, a 5,000 square foot building with a 25' concrete apron and a proposed gravel access road Swales will be constructed to capture site sheet flows A swale is proposed to capture runoff from the west side of the building and directed east into the detention pond, located on the south east corner of the site Another swale is proposed to capture runoff from the sheet flows from the storage yard and will be located next to the access road Flows from this swale will be directed south to the detention pond All flows from the B1 basin are routed to the detention pond outlet structure at the southeast corner of the pond The pond outlet structure will discharge into an existing road side ditch located next to County Road 103 to match historical the flow path Basins B2: Basin B2 (14 01 acres) consists of the western portion of the site that will remain undeveloped Runoff sheet flows to the south where it continues offsite Basin B2 will not be disturbed and flows from this area will follow historic conditions off site Basins B3: Basin B3 (0 49 acres) consists of the east corner of the site on the outer side of the proposed detention pond Runoff from this undeveloped naturally vegetated basin will sheet flow east offsite to the road side ditch next to County Road 103 Basin OS1 Basin OS1 (15 97 acres) is a basin located offsite to the north of basin B1 Basin OS1 is currently an undeveloped area of land that sheet flows across the proposed site Flows from this basin flow directly into basin B1 and will be accounted for in regards to the detention pond spillway calculations a. Rational Method Calculations The runoff from proposed basins were calculated using the Rational Method as they are smaller than 90 acres The 10 -year and 100 -year criteria were used for the minor and major storm events Impervious values were assumed based off the SDDTC of weld county requirements The results of the Rational Method analysis for the developed conditions can be found in Appendix C Lamp Rynearson, Inc Preliminary_ Drainage Report for Mallard Exploration Field Office Project No 0220014 01 March 2021 Page 4 Table 2 — Rational Method Calculations — Proposed Conditions DEVELOPED BASIN CALCULATIONS , DESIGN POINT BASIN AREA Imperviousness % tc O.0 C100 Q10 Q100 B1 B1 2099 33 0% 337 039 057 1887 4567 B2 B2 14 01 2 0% _ 41 3 0 26 0 51 7 15 23 23 OS1 O51 16 23 2 0% 48 6 0 26 0 51 7 55 23 67 B3 B3 , ^ 0 49 6 0% 25 0 0 28 0 52 0 37 1 13 TOTAL 51 72 15 0% NA NA NA 33 94 93 70 b. Water Quality & Detention Ponds Stormwater quality will be mitigated onsite during construction with the use of sediment control logs, vehicle tracking devices and inlet/outlet protection devices Long-term stormwater quality will occur by routing the onsite drainage through grass buffers and vegetated swales The detention basin used for this site is classified as an extended detention basin according to the Urban Storm Drainage Criteria Manual Volume 2 This construction will allow for the full, required capture volume of the 100-yr with one foot of freeboard The required volume was calculated utilizing WQCV, 10-yr and 100-yr values obtained from the UD-Detention spreadsheet This spreadsheet can be found within Appendix C and meets county and industry standards For this detention basin, Colorado law requires the WQCV to drain within 40 hours, 99% of the 10 -year event to drain within 72 hours and 99% of the 100 -year event to drain within 120 hours Currently, the WQCV is set to drain in 40 hours For the 10 -year event, time to drain 97% of Inflow volume is 62 hours and time to drain 99% of inflow volume is 71 hours For the 100 -year event, time to drain 97% of inflow volume is 103 hours and time to drain 99% of inflow volume is 116 hours The spillway crest will be placed at the 100-yr water- surface elevation and will accommodate the extreme rainfall events The spillway will be nprapped and facilitate flows to continue to adjacent drainage conveyances, ultimately terminating to the road side ditch next to County road 103, following historic patterns The calculations for the detention pond and spillways, along with pond stage -storage information are included in Appendix C Table 3 below provides a summary of the detention pond parameters Table 3 — Parameter for Detention Pond Parameter Proposed Design WQCV (ac -ft) 0 358 10-yr Storage Required (ac -ft) 1 572 100-yr Storage Required (ac -ft) 3 834 Storage Capacity (ac -ft) (Not including 1' freeboard) 4 051 Lamp Rynearson, Inc Preliminary Drainage Report for Mallard Exploration Field Office Project No 0220014 01 March 2021 Page 5 Water Surface Elevation at WQCV (ft) 4904 17 Water Surface Elevation at 10-yr (ft) 4905 19 Water Surface Elevation At 100-yr (ft) 4906 13 Minimum Freeboard (ft) 1 Pond Depth (Bottom to spillway crest (ft) 2 34 Pond Embankment Elevation (Top of pond (ft) 4907 13 Minimum Effective Pond Elevation (Bottom Elevation) (ft) 4903 79 Outlet Pipe Diameter (in) 18 10-yr Historic Outlet Release Rate (cfs) 18 95 100-yr Pond Relese Rate (cfs) 9 7 Spillway Crest Elevation (ft) 4906 13 c. Erosion Control Based on the swale size calculations provided in Appendix C, the average flow velocities for the 100 -year storm event are well below the eroding velocity of 5 feet per second, therefore, lining the swales with native vegetation/grass is sufficient to provide protection against any potential erosion and there is no need to provide any hard lining such as nprap for swales As stated within section c above, the ponds during all phases of the process will be protected with nprap See appendix C for supporting calculations Conclusions When developed, the site's runoff will increase and be detained, thereby reducing released flows back to historic values The proposed swales will capture the runoff from the site and route the storm flows to the proposed detention pond and eventually into the road side ditch next to County road 103 All drainage design considerations contained in this drainage report are in general accordance with the Weld County Charter and County Code Storm Drainage Cntena, Weld County Engineering & Construction Cntena and the Mile -High Flood District Storm Drainage Cntena Manuals In general, the design presented in this report serves to provide a safe and adequate drainage system for the Mallard Exploration field office development E.

From I-25 and Tri-Town Study, Volume 2, Chapter 2, page 20 5.4.3 Larger Basin Rainfall Methods As noted above, the Rational Method should not be used to determine runoff for basins larger than 160 acres. In areas located in the southwest portion of Weld County and where areas are larger than 160 acres that have drainage characteristics similar to an urban area, the Colorado Urban Hydrograph Procedure (CUHP) is an acceptable model for determining runoff amounts. The CUHP model can be used for basins from 0 to 3,000 acres. The parameter adjustments provided in the runoff chapter of the UDFCD Manual (Volume 1) should be used when dealing with basins that are larger than 160 acres. The CUHP model is not applicable in non -urban areas, including those areas in Weld County that are outside of the Denver metropolitan area. The U.S. Army Corps of Engineers (USACE) HEC-HMS model is more applicable for mixed suburban -agricultural areas. The HEC-HMS model can be used on watersheds and drainage basins larger than 160 acres provided the modeling follows the parameters in the HEC- HMS User's Manual, the HEC-HMS Technical Reference Manual, and the HEC-HMS Application's Guide. WELD COUNTY ENGINEERING & CONSTRUCTION CRITERIA Page 138 DRAINAGE CRITERIA MANUAL (V 1) RUNOFF 2 0 RATIONAL METHOD For urban catchments that are not complex and are generally 160 acres or less in size, it is acceptable that the design storm runoff be analyzed by the Rational Method This method was introduced in 1889 and is still being used in most engineering offices in the United States Even though this method has frequently come under academic criticism for its simplicity, no other practical drainage design method has evolved to such a level of general acceptance by the practicing engineer The Rational Method properly understood and applied can produce satisfactory results for urban storm sewer and small on -site detention design 21 Rational Formula The Rational Method is based on the Rational Formula Q = CIA in which Q= the maximum rate of runoff (cfs) (RO-1) C = a runoff coefficient that is the ratio between the runoff volume from an area and the average rate of rainfall depth over a given duration for that area / = average intensity of rainfall in inches per hour for a duration equal to the time of concentration, tC A= area (acres) Actually, Q has units of inches per hour per acre (in/hr/ac), however, since this rate of in/hr/ac differs from cubic feet per second (cfs) by less than one percent, the more common units of cfs are used The time of concentration is typically defined as the time required for water to flow from the most remote point of the area to the point being investigated The time of concentration should be based upon a flow length and path that results in a time of concentration for only a portion of the area if that portion of the catchment produces a higher rate of runoff The general procedure for Rational Method calculations for a single catchment is as follows 1 Delineate the catchment boundary Measure its area 2 Define the flow path from the upper -most portion of the catchment to the design point This flow path should be divided into reaches of similar flow type (e g , overland flow, shallow swale flow, gutter flow, etc ) The length and slope of each reach should be measured 3 Determine the time of concentration, tc, for the catchment 2007-01 Urban Drainage and Flood Control Distnct RO-3 RUNOFF DRAINAGE CRITERIA MANUAL (V 1) 4 Find the rainfall intensity, I, for the design storm using the calculated tt and the rainfall intensity -

However, in practice, the time of concentration can be an empirical value that results in reasonable and acceptable peak flow calculations. The time of concentration relationships recommended in this Manual are based in part on the rainfall -runoff data collected in the Denver metropolitan area and are designed to work with the runoff coefficients also recommended in this Manual. As a result, these recommendations need to be used with a great deal of caution whenever working in areas that may differ significantly from the climate or topography found in the Denver region. For urban areas, the time of concentration, 1., consists of an initial time or overland flow time, t,, plus the travel time, 1,, in the storm sewer, paved gutter, roadside drainage ditch, or drainage channel. For non - urban areas, the time of concentration consists of an overland flow time, 1,, plus the time of travel in a defined form, such as a swale, channel, or drainageway. The travel portion, 1,, of the time of concentration can be estimated from the hydraulic properties of the storm sewer, gutter, swale, ditch, or drainageway. Initial time, on the other handwill vary with surface slope, depression storage, surface cover, antecedent rainfall, and infiltration capacity of the soil, as well as distance of surface flow. The time of concentration is represented by Equation RO-2 for both urban and non -urban areas: in which: 1 = time of concentration (minutes) 1, = initial or overland flow time (minutes) 1, = travel time in the ditch, channel, gutter, storm sewer, etc. (minutes) 2.4.1 Initial Flow Time The initial or overland flow time, 1,, may be calculated using equation RO-3: 0.3951.1- C; )II_ S+ 0.33 in which: 1, = initial or overland flow time (minutes) C'; = runoff coefficient for 5 -year frequency (from Table RO-5) 2007-01 Urban Drainage and Flood Control District (RO-2) (RO-3) RO-5 RUNOFF DRAINAGE CRITERIA MANUAL (V. 1) L = length of overland flow (500 ft maximum for non -urban land uses, 300 ft maximum for urban land uses) S = average basin slope (ft/ft) Equation RO-3 is adequate for distances up to 500 feet. Note that, in some urban watersheds, the overland flow time may be very small because flows quickly channelize. 2.4.2 Overland Travel Time For catchments with overland and channelized flow, the time of concentration needs to be considered in combination with the overland travel time, t,, which is calculated using the hydraulic properties of the swale, ditch, or channel. For preliminary work, the overland travel time, t,, can be estimated with the help of Figure RO-1 or the following equation (Guo 1999): V _ C, Si 5 ttt in which: = velocity (ft/sec) = conveyance coefficient (from Table RO-2) S„ = watercourse slope (ft/ft) Table RO-2 Conveyance Coefficient, C.

The first design point is the point where runoff first enters the storm sewer system. An example of definition of first design point is provided in Figure RO-2. Normally, Equation RO-5 will result in a lesser time of concentration at the first design point and will govern in an urbanized watershed. For subsequent design points, the time of concentration is calculated by accumulating the travel times in downstream drainageway reaches. 2.4.4 Minimum Time of Concentration Should the calculations result in a t. of less than 10 minutes, it is recommended that a minimum value of 10 minutes be used for non -urban watersheds. The minimum lc recommended for urbanized areas should not be less than 5 minutes and if calculations indicate a lesser value, use 5 minutes instead. 2.4.5 Common Errors in Calculating Time of Concentration A common mistake in urbanized areas is to assume travel velocities that are too slow. Another common error is to not check the runoff peak resulting from only part of the catchment. Sometimes a lower portion of the catchment or a highly impervious area produces a larger peak than that computed for the whole catchment. This error is most often encountered when the catchment is long or the upper portion contains grassy parkland and the lower portion is developed urban land. 2.5 Intensity The rainfall intensity, I, is the average rainfall rate in inches per hour for the period of maximum rainfall of a given recurrence frequency having a duration equal to the time of concentration. After the design storm's recurrence frequency has been selected, a graph should be made showing rainfall intensity versus time. The precipitation-intesity curve can be found on the NOAA Atlas 14 website for site specific rain gages. The intensity for a design point may be taken from the graph or calculated through the use of Equation RA -3 using the calculated r, and the 1 -hour point rainfall depth (inches). 2.6 Watershed Imperviousness All parts of a watershed can be considered either pervious or impervious. The pervious part is that area where water can readily infiltrate into the ground. The impervious part is the area that does not readily allow water to infiltrate into the ground, such as areas that are paved or covered with buildings and sidewalks or compacted unvegetated soils. In urban hydrology, the percentage of pervious and impervious land is important. The percentage of impervious area increases when urbanization occurs 2007-01 Urban Drainage and Flood Control District RO-7 RUNOFF DRAINAGE CRITERIA MANUAL (V. 1) and the rainfall -runoff relationships change significantly. The total amount of runoff volume normally increases, the time to the runoff peak rate decreases, and the peak runoff rates increase. Photograph RO 2 —Urbanization (impervious area) increases runoff volumes, peak discharges, frequency of runoff, and receiving stream degradation. When analyzing a watershed for design purposes, the probable future percent of impervious area must be estimated. A complete tabulation of recommended values of the total percent of imperviousness is provided in Table RO-3 and Figures RO-3 through RO-5, the latter developed by the District after the evolution of residential growth patterns since 1990. 2.7 Runoff Coefficient The runoff coefficient, C, represents the integrated effects of infiltration, evaporation, retention, and interception, all of which affect the volume of runoff. The determination of C requires judgment and understanding on the part of the engineer. Based in part on the data collected by the District since 1969, an empirical set of relationships between C and the percentage imperviousness for the 2 -year and smaller storms was developed and are expressed in Equations RO-6 and RO-7 for Type A and C/D Soil groups (Urbonas, Guo and Tucker 1990). For Type B soil group the impervious value is found by taking the arithmetic average of the values found using these two equations for Type A and Type C/D soil groups. For larger storms (i.e., 5-. 10, 25-, 50- and 100 -year) correction factors listed in Table RO-4 are applied to the values calculated using these two equations.

Use of these coefficients and this procedure outside of the semi -arid climate found in the Denver region may not be valid. The UD-Rational spreadsheet performs all the needed calculations to find the runoff coefficient given the soil type and imperviousness and the reader may want to take advantage of this macro -enabled Excel workbook that is available for download from the Weld County website. See Examples 7.1 and 7.2 that illustrate the Rational method.

Discuss the existing and proposed potable water source. If utilizing a drinking water well, include either the well permit or well permit application that was submitted to the State Division of Water Resources. If utilizing a public water tap, include a letter from the Water District, a tap or meter number, or a copy of the water bill. A proposed, commercial exempt water well will be utilized. The water well permit application is included with this USR Submittal. There is an existing stock water well on the full half section property. That well will remain on the larger property and the proposed well will be located over 800' away within the new 35 acre property once the property is split via exemption plat. 2. Discuss the existing and proposed sewage disposal system. What type of sewage disposal system is on the property? If utilizing an existing on -site wastewater treatment system, provide the on -site wastewater treatment permit number. (If there is no on -site wastewater treatment permit due to the age of the existing on -site wastewater treatment system, apply for an on -site wastewater treatment permit through the Department of Public Health and Environment prior to submitting this application.) If a new on -site wastewater treatment system will be installed, please state "a new on -site wastewater treatment system is proposed." (Only propose portable toilets if the use is consistent with the Department of Public Health and Environment's portable toilet policy.) A new on -site wastewater treatment is proposed. A new commercial on -site wastewater treatment system permit will be applied for concurrently with this USR application. The approximate design and location of the on -site wastewater treatment system has been shown on the USR Map. 3. If storage or warehousing is proposed, what type of items will be stored? In the storage yard, oilfield related items and large equipment would be kept on -site in a neat and orderly manner, including: • Up to 10 Conex Containers to securely store tools, parts, and equipment • 1,000 -gallon diesel fuel tank • Two 1,000 -gallon propane tanks • Surplus oil and gas facility equipment for use on future locations Omaha Fort Collins Lakewood Kansas City • Temporary staging of a drilling rig or storage of rig related equipment • Surplus drilling pipe No hazardous materials would be kept on the grounds. 4.

Also, the Storm Water Management Plan will be followed to mitigate soil erosion during the construction phase. After construction is completed, the site will be stabilized using native vegetation, which will not be allowed to grow over 12" high. Additionally, Mallard Exploration will gravel the access drive and circulation pattern. In addition, a water truck will be utilized to control dust after construction, if required. On - site vehicle speeds will be restricted to reduce the amount of dust generated. Please feel free to contact me at 970-226-0342 or via email at michael.palizzi@lamprynearson.com. Michael Palizzi, PE Project Manager Lamp Rynearson Omaha Fort Collins Lakewood Kansas City LAMP RYNEARSON March 26, 2021 Weld County Public Works 1555 N. 176 Avenue Greeley, Colorado 80631 RE: Lighting Report Mallard Exploration Field Office 4715 Innovation Dr., Ste. 100 Fort Collins, CO 80525 [P] 970.226.0342 [Fl 970.226.0879 LampRynearson.com The project site is located in the southeast quarter of Section 9, Township 8 South, Range 60 West of the 6th P.M., or about 13 miles west of the Town of Raymer, Weld County, Colorado. More specifically, the site is situated 2 miles north of Highway 14, and just west of Weld County Road 103. There are open undeveloped fields surrounding the site to the north, east, and west. The property to the south has multiple oil and gas pads, with an existing gravel access road. The proposed site has a proposed gravel access road on the southeastern portion of the property. Lighting Plan following the standards set forth in Chapter 23, Article II, Division 4 and the Dark Sky Policy, if applicable. The following document outlines Mallard Exploration ("Mallard") Lighting Plans for the Mallard Exploration Filed Office Permit Application. All permanent lighting fixtures installed at the field office site shall comply with the lighting standards of the Weld County Charter and County Code and Dark Sky Policy. The intent of this provision is to minimize light spillage beyond the perimeter of the field office site. All permanent lighting will be downward facing. All bulbs will be fully shielded to prevent light emissions above a horizontal plane drawn from the bottom of the fixture. Specific to the site, lighting will be placed on all sides of the proposed building with more in front to help illuminate the parking area. A light pole will be placed just outside of the gravel access pad on the northeast corner, in-between the gravel drive aisle and storage yard. This light pole will help illuminate the area around the fuel tank in the storage yard and the north east area of the building. Another light pole will be placed on the south end of the parking area to capture the parking lot and the southeast side of the building. Key design criteria for lights: • Dark sky compliant (low light pollution). • Contain no mercury or other hazardous substances. • Energy -efficient technology - up to 65% energy savings over HID fixture. • All lighting fixtures will be downward facing. Omaha Fort Collins Lakewood Kansas City Due to the setback location (approximately 1,000' west) of the proposed field office, no light spillage will reach WCR103. There are no proposed lights along the access road or storage yard. Light fixtures will be designed to produce 0.0 foot-candles at the property lines.
