UNIT #6 EVANS, Co 80620 970-330-0308 Introduction Ursa Major Technologies, Inc. (UMT) is an aerospace technology company based in Berthoud, Colorado that specializes in jet propulsion. Their primary focus is assembly and testing of small to medium sized rocket engines. The types of engines they test are not the large rocket ship launch engines but are much smaller engine types used for low earth and geostationary orbit. The company is expanding and needs a large property in a lightly populated area to construct a new testing facility capable of meeting their current and expected future demands. UMT has selected a large property, approximately % of section 8, township 7N, range 63W, near Galeton in Weld County for their new Rocket Test Facility (RTF). Below is a description of the proposed project being submitted for a Use by Special Review (USR) application with Weld County. UMT has contracted Alles, Taylor & Duke, LLC and Freeman Architects to provide planning and design services during the USR process.

The five parcels will be combined into one parcel after USR approval is obtained. Reference the Property Vicinity Map in Figure 1 below. The property is currently used as pastureland for cattle and is encompassed and divided up by barbed wire fencing. Native prairie grasses and sage brush cover most of the lot, and on the steeper banks of Coal Creek the ground is bare. There is also a water well, Colorado Division of Water Resources Well Permit 153242-A dated January 30, 1989, in the northern center of the combined parcels that is pumped by a windmill into a livestock water tank. No other irrigation equipment is used on the property. WCR 63 Right -of -Way (ROW) extends to the property from WCR 78, but this stretch of WCR 63 is not maintained by Weld County. Access to ALLES TAYLOR & DUKE, LL LICENSED PROFESSIONAL ENGINEERS LICENSED PROFESSIONAL LAND SURVEYORS 3610 35TH AVE. UNIT #6 EVANS, CO 80620 970-330-0308 the property is from WCR 63 through a barbed wire gate at the northwestern corner of the property, near where WCR 84 would be located. From there a wagon trail type road goes east to the water well and livestock water tank area. Overhead electrical and telephone lines run past the subject property along the west side of WCR 63, and a 20' ROW Easement for Poudre Valley Rural Electrical Association, dedicated October 15, 2€ 13, at Reception No. 3970907, extends east of WCR 63, where WCR 82 would be, to the eastern property line of the subject property. Several underground gas and oil lines run parallel to the electrical ROW Easement in a 3O' wide Pipeline Easement, dedicated November 13, 2012, at Reception No. 39709O7 that overlaps the electrical easement, to the well site just east of the subject property. Figure 1. Property Vicinity Map Zoning & Surrounding Land Uses The subject property is zoned Agriculture (AG), as are the majoring of the surrounding properties. Multiple well sites for oil and gas production exist on all sides of the subject property and are dispersed throughout the immediate vicinity. The closest residential structure is just over 1 mile away to the southeast of the southernmost property boundary, with a light density of houses on large lots dispersed along WCR 63 a n d WCR 65 from here to Highway 392. The southern property boundary used to be ROW for WCR 82, however the ROW was vacated by Weld County on April 6, 1959 (Reception No. 1301745). Long's Peak Dairy is approximately 2 mile west of the site, and the closest houses to the north are near Highway 14, 2.5-3 miles away. All surrounding land is used for agricultural related purposes, oil and gas wells, and private residences. A property 1/2 mile to the west has an active USR permit fora shooting 3 ALLES TAYLOR & DUKE, LL LICENSED PROFESSIONAL ENGINEERS LICENSED PROFESSIONAL LAND SURVEYORS 3610 35TH AVE. UNIT #6 EVANS, CO 80620 970-330-0308 range, MUSR13-0012, and at the northeast corner of WCR 61 & 78, approximately 2 miles southwest, there is a large livestock operation under another USR permit, MU5R16-00009. North of the property is mainly farmland and the Pawnee National Grasslands. The northern area is largely uninhabited with few public roads until Highway 14 directly north approximately 3 miles of the northern property line. While there is now a diner and coffee shop in Galeton, the closest town with existing commercial services is Eaton, approximately 17 miles west of the subject property. UMT wants to expand their assembly and testing service capabilities to a location that won't disturb neighbors. The near 400 -acre property is in a sparsely populated area within Weld County and fits the company's criteria for the RTF project exactly. While the proposed land use is not agricultural in nature, the selected location allows for the industrial style use by UMT to cause the least amount of impact to existing residents, businesses, and livestock currently in the area. Coal Creek Floodplain Coal Creek runs from Pawnee National Grasslands in the north to Crow Creek in the south near Highway 392. The subject property is approximately 5.3 miles north of Crow Creek along the Coal Creek tributary. Relatively close to the bottom of the contributing watershed approximately 80 sq. miles drains of sparsely used farm/ranch land and open grassland prairie to Coal Creek as it runs through the subject property. A FEMA Flood Panel is not published for Coal Creek, Panel No. 08123C1300E, but it is a major drainage way between the Pawnee National Grasslands (also unpublished) and Crow Creek, which is a published floodplain, Panel No. 08123C1600E. Since most of the Coal Creek watershed is the Pawnee National Grasslands, it is likely that FEMA did not map floodplains in the area since little to no development was expected besides irrigated farms and grazing land. The unpublished floodplain in Coal Creek was analyzed by ATD, within the boundaries of the subject property, to determine the limits of the expected 100 -year (1% probability) storm flows to protect sensitive testing equipment from flood damage by keeping it out of the determined floodplain limits. Reference the Drainage Narrative included with this USR submittal for details about the floodplain analysis. Reference Figure 2 below for an image of the 100 -year floodplain (purple hatched area) on the subject property.

Coal Creek 100-yr Floodplain Boundary USGS WebSoils Survey Based on information gather from the USGS Websoils Survey database, the site is mainly sandy loam and fine sandy loam with areas of Renohill-Shingle complex, reference Table 1 below for site soils descry pti. The h yd rologi sods gro a for the va rious soy l types a re A, B a nd D a nd the typical slope ranges from 0% to 9%, however some areas going into the creek bed have higher slopes. The soils northwestern area of the subject property has the soils most favorable for septic system, and the soils found in the area are adequate for commercial/industrial building foundation systems. Within the creek bed the ground water may be seasonally higher based on regional precipitation leading to saturated and unstable soils with increased corrosion potential.

UNIT #6 EVANS, CO 80620 970-330-0308 The site will be accessed via WCR 63 along the western edge of the property near the proposed office/warehouse buildings. UI MT wants to improve WCR 63, from WCR 78 to the proposed access, based on the current condition of WCR 63 and the needed service level for the expected traffic generated by the project. We are planning to widen the road and provide a heavy-duty gravel road section with the proposed site development. WCR 63 ends at the northern section line where WCR 84 would be, and there is only a few well sites to west that use WCR 63 north of WCR 80 other than farmers. The facility will be built out over time with the initial phase of construction only including items planned on the west side of Coal Creek. It is expected that only one of the warehouse/office buildings, one bulk storage area, and three of the test sites will be built in the initial phase of construction. Then an additional office/warehouse building, and one or two test sites will be added incrementally depending on demand and desired business operations. Below is a table representing the expected timeline for the improvements proposed under this USR. Table 2. Preliminary Construction Schedule and Phasing Construction Phase Expected Dates Improvements Phase I June /22 Nov Initial office/warehouse construction of l internal 3 test sites, Roads, and Widen 1 bulk WCR storage 63, 1 , — Phase II April '24 — Sep '24 Add 1 office/warehouse and 2 test sites Phase III April '27 — Sep '27 Add 1 office/warehouse, 2 test sites, and 1 bulk storage area Phase IV April '32 — Sep '32 Add 1 office/warehouse, equipment storage, and 2 test sites Construction dates are approximate based on expected future growth. Factors triggering future phases are dependent of business needs and may happen sooner or later than expected. Business Operations Ursa Major Technologies, inc. is currently headquartered in Berthoud on a 90 -acre parcel just west of Interstate -25 (I-25) that is in relatively close to an urbanizing area and adjacent to a residential neighborhood. The current facility has two test buildings with a few attached offices where the current 10-15 employees work, Monday through Friday, 8 am to 6 pm. The new Galeton-RTF will initially operate with approximately 20 full time employees during normal hours, Monday -Friday Sam to 6pm, to avoid causing disturbances in the evening, night, and early morning hours. Depending on the work load they may also include Saturday operations periodically. Their work for is expected grow up to (75) seventy-five employees (up to 20 per building) over the next ten years. There will be no public access allowed at the facility, but groups of visitors may visit the site periodically. We anticipate that large groups of visitors will carpool by van or bus as a part of an organized tour. The project will generate incremental increases in daily traffic from employees and deliveries as the facility is expanded. The peak traffic hours for the site are expected to be 1/2 hour before and after the workday. A breakdown of the expected traffic generated by the proposed initial facility construction and full build -out is provided in Table 3 below. 8 ALLES TAYLOR & DUKE, LLC LICENSED PROFESSIONAL ENGINEERS LICENSED PROFESSIONAL LAND SURVEYORS Table 3.

Trucks/Semi traffic count is doubled to convert to equivalent passenger traffic impact. UMT uses multiple methods to ensure that it operates in a manner that is safe for its personnel and the public. Their rocket test facilities not only to comply with all local, state, federal requirements, but also to the Department of Defense and NASA requirements for rocket engine testing. Safety drills are performed monthly by personnel involved with rocket engine testing. Joint training between UMT and our local fire department ensures that if an emergency were to occur everyone is prepared. A dedicated safety operator is assigned for each test in case an emergency occurs, and operators ensure that test area are clear of personnel by use of multiple video cameras, two-way radios, and walk-through by personnel. Office/Warehouse Buildings The office/warehouse buildings will be located near WCR 63 in the center of the western half of the subject property. The existing gate from WCR 63 is at the very northwest corner of the property, but the proposed access will be moved approximately 1,000 ft south of the existing gate to an area in the property more suited for central oversight of the facility. There are no other access points along WCR 63 between WCR 84 and WCR 82 at the time this USR was submitted. A security gate will be constructed to control site traffic approximately 65 ft from the western edge of WCR 63 ROW which will allow for truck stacking during admittance. A total of (4) four 9,450 ft' buildings are planned for the ultimate project build -out. The buildings are proposed to be grouped together in the center of western 1/3 of the property. The buildings will be split in half with one side being offices and the other warehouse portion will be used for assembly and pre- test inspections. The buildings will be one story metal buildings with metal siding and will be industrial style. Each building will have covered em ployee parking on three sides, and the fourth side will be the front of the office and warehouse overhead door(s). The covered parking roof structure will be attached to the building and cantilevered to avoid columns. See preliminary building elevations. Visitor and company vehicle parking will be provided in front of the office along with (1) one ADA compliant parking spot, and the entire building will be surrounded by a 25 ft wide concrete apron. Gravel drive lanes, 25 ft ALLES TAYLOR & DUKE, LL LICENSED PROFESSIONAL ENGINEERS LICENSED PROFESSIONAL LAND SURVEYORS 3610 35TH AVE. UNIT #6 EVANS, CO 80620 970-330-0308 wide minimum, and additional parking areas will be provided as needed near the buildings. The buildings are oriented to block prevailing winds and provide the most sun on the front to facilitate precipitation melting/drying and prevent weather restrictions on the main doors being used. Exterior lights will be mounted on the building and parking canopies, and pole mounted lights will be included in the truck staging area and at the site security gate. All site lighting will be downcast type fixtures meeting the International Dark -Sky Association guidelines. Dumpsters will be provided for common office waste handling for each building. The trash enclosure will be made of CU blocks with steel doors. UMT plans on hiring a local refuse collection service to provide the dumpster and weekly removal of the discardable wastes generated by the facility. No hazardous wastes will be generated during regular operations. No scrape or discarded material stockpiles will be kept on -site. Potable domestic water will be supplied by the existing water well which will be converted to commercial use with the Colorado Division of Water Resources upon USR approval. The maximum annual usage for a commercial permit is 108,000 gallons. Based on the 15 gallon per day demand per person required by Weld County Code Chapter 30 for On -site Wastewater Treatment Systems (OWTS) Regulation, a maximum of (20) twenty people can be served by the existing well annually. A meter will be installed on the first building constructed to monitor well water usage and verify the per employee capacity of the well. This will provide UMT will important information for future expansion of the Galeton-RTF. A water filtration and treatment system will be constructed on -site to treat the well water before entering independent cisterns with pumps providing water for each building. The well water will mainly be used for bathrooms and bottled water/water coolers will be provided for the employees to have drinking water. Preliminary septic system calculations have been performed based on the expected site soils being classified as a Type 3 per the USDA method for soils classification. We anticipate being able to use one standard rowed gravity septic system with a 2,000 -gallon septic tank and 2,130 ft2 soil treatment area to be able to serve two buildings or 40 people daily. Equipment Maintenance Building A 9,600 ft2 equipment maintenance building is planned at the east end of the main area. The building will be used for operations equipment, road maintenance equipment, and personnel transport vehicle storage. Diesel will be stored outside the warehouse in portable fuel cubes within concrete containment walls. Engine Test Sites The proposed engine test sites will be 40,000 ft2 areas scattered throughout the property along the banks of Coal Creek. The sites are setback 600 ft from the exterior property lines, other test sites, and bulk storage areas for safety with enough space for eleven possible locations within the subject property. Each engine test site will be evaluated for sound levels at the property line by UMT aerospace engineers and a Sound Report is provided with this USR submittal. The test pads will be cut into the sides of the existing slopes on the property to create natural berms around the blast area. This area will be covered with rip -rap aggregate and kept free of vegetation or other combustible materials to create a fire break around the testing site. The engine testing will be done in a test control building, 10 A ,:. ,S. hp I -h -I -F 47 T D 4' jI ALLES TAYLOR & DUKE, LL LICENSED PROFESSIONAL ENGINEERS LICENSED PROFESSIONAL LAND SURVEYORS 3610 35TH AVE. UNIT #6 EVANS, Co 80620 970-330-0308 approximately 1,200 ft2, situated on a concrete pad in the center of the test site and directed towards the uphill side of the slopes. The test stands will be situated within the buildings so the engine exhaust cone is just inside the uphill face of the building firing through a 16 ft wide door. The test sites will be connected through the property via 16 ft wide light -duty gravel roads that loop around the property to provide two directions of access to each site. On average one test stand can perform 5 tests per twelve-hour workday. Each test takes anywhere from 5 seconds to 5 minutes to conduct with several hours needed for test preparation and breakdown. Each test site will be continuously operating during business hours for a total of 20-30 minutes of actual rocket engine firing per site. The natural terrain across the subject property makes it ideal for locating each site to utilize the space and slopes to minimize noise levels for neighbors. UMT will use a combination of control methods to reduce the chances of a brush fire at the testing sites. Our test stands employ a fire suppression system based on liquid nitrogen that can extinguish any fires in under 1 minute that may start due to testing. The test sites are designed to have no vegetation within a minimum of 25 ft of the building, piping, tanks, or potential leak points. Existing vegetation height within an additional 75 ft, minimum, around the testing site will be kept to one foot or less. The side of the testing buildings where the engines are fired through will have a total of 120 ft, minimum, of non- combustible ground cover beyond the building face. The rocket engine mounting height above ground, and location of any berms will be such that the rocket plume will not be hot enough to start a fire. UMT consults with a Fire Protection Engineer during site design and after construction to ensure our testing facilities are safely operated. Bulk Tank Storage Sites The facility will be set up with two bulk storage areas that will house the large tanks and tube trailers for the various fuels and gases needed for rocket engine testing. The bulk tanks will be connected to run tanks located at each test site via an internal network of pipes. The bulk storage sites are located to provide ease of access for the large semi -trucks used to deliver the fuels, and centralized piping hubs for all the proposed testing sites. The roads to the bulk storage areas are 26' wide heavy-duty gravel roads designed to accommodate fully loaded tanker trailers. Each site is approximately 40,000 ft2 and can fit up to (10) ten 25 ft diameter tanks with secondary containment, and (4) four 28 ft long tube trailers. Table 4.

Due to limited availability, we cannot use water to control dust. The amount of internal traffic will be low and internal speed limits kept under 20 mph. Magnesium chloride will be used periodically to help reduce the level of dust generated by traffic on internal roads. UT's rocket engines are clean burning and do not produce harmful pollutants. The natural topography will be used along with cutting the testing sites into the hill sides to deflect noise. A Noise Study was provided by UMT based on the effects of the proposed grading and testing site locations and is included with this submittal. Economic Impact The proposed use would create dozens of high paying jobs in Weld County. The present headquarters for UMT is in Berthoud, Colorado. Due the rapid growth of the Company, UMT has outgrown the Berthoud facility and needs more space. However, the Berthoud facility will remain in operation for some testing of rocket engines and as the company headquarters. The (10) ten-year plan, covered by this USR application, is for up to 80 employees at the Galeton site. As time progresses, the size of the rocket engines may increase. Beyond the (10) ten-year plan, the number of employees may exceed 100, at which time an Amended USR will be applied for to address the additional site uses. USE BY SPECIAL REVIEW (USR) PLANNING QUESTIONNAIRE 12/15/2113 Answer the following questions per Section 23-2-260. A, B, C & E of the Weld County Code. Please type on a separate sheet. !fa question does not pertain to your proposal, please respond with an explanation — do not leave questions blank. 1. Explain the proposed use and business name. Ursa Major Technologies, Inc Rocket Test Facility near Galeton, Colorado 2. Explain the need for the proposed use. Ursa Major Technologies, Inc. (UMT) is an aerospace technology company based in Berthoud, Colorado that specializes in jet propulsion. Their primary focus is assembly and testing of small to medium sized rocket engines. The types of engines they test are not the large rocket ship launch engines but are much smaller engine types used for low earth and geostationary orbit. The company is expanding and needs a large property in a lightly populated area to construct a new testing facility capable of meeting their current and expected future demands. UMT has selected a large property, approximately of section 8, township 7N, range 63W, near Galeton in Weld County for their new Rocket Test Facility (RTF). 3. Describe the current and previous use of the land. The existing site use is as dryland pasture, this site is able to graze approximately 25 head of cattle on a year-round basic, per the present property owner. 4. Describe the proximity of the proposed use to residences. The closest residential home site is located 1.2 miles to the southeast with other homes in the surrounding area being at least 1.4 miles from the site. 5. Describe the surrounding land uses of the site and how the proposed use is compatible with them. This site has been chosen due to its remote location and Topographic features. The closest residential home site is located 1.2 miles to the southeast with other homes in the surrounding area being at least 1.4 miles from the site. The rocket engine test pads are proposed in low laying areas of the site and the site topography will be used to dampen the sound generated during the rocket engine testing. Noise reports are being prepared or have been prepared by UMT's aerospace engineers. 6. Describe the hours and days of operation (i.e. Monday thru Friday 8:00 a.m. to 5:00 p.m.). Normal business hours, Monday -Friday Sam to 6pm, to avoid causing disturbances in the evening, night, and early morning hours. Depending on the work load they may also include Saturday operations periodically. 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 the new RTF will operate with approximately 20 full time employees. Future expansion of their workforce up to 75 employees (up to 20 per building) over the next ten years. No shift work is proposed, the hours of operation are from Sam to 6pm. 8. Describe the maximum number of users, patrons, members, buyers or other visitors that the site will accommodate at any one time. There will be no public access allowed at the facility, but groups typically no larger than (10) ten visitors at a time will visit the site periodically. We anticipate that large groups of visitors will carpool by van or bus. 9. List the types and maximum numbers of animals to be on the site at any one time (for dairies, livestock confinement operations, kennels, etc.). No livestock or animal confinement is proposed. Employees may bring a household pet to work with them. 10. List the types and number of operating and processing equipment. No manufacturing or processing on -site. 11. List the types, number and uses of the existing and proposed structures. There presently no structures on -site. The proposed facility will include (4) four 135'x70' (9,450 ft ) warehouse/office buildings, (2) two chemical/fuel bulk storage locations, and up to (12) twelve 100'x100' (10,000 ft') rocket engine test sites each containing a 40540' test facility, developed over a ten year period. 12. Describe the size of any stockpile, storage or waste areas. No material stockpiles are proposed. Storage of scrap metals will occur in containers that are stored inside the assembly and pretesting areas. Trash enclosures are proposed at the main buildings, trash enclosures are not proposed at the test sites, all waste generated at the test sites will be collected in trash cans and transported to the trash enclosures at the main building. 13. Describe the method and time schedule of removal or disposal of debris, junk and other wastes associated with the proposed use. Scrape metals will be disposed of as necessary. No equipment maintenance, other than preventative maintenance, is proposed on site. Trashservices will be contracted, and a schedule will be setup for the services, it is assumed that office dumpsters will be emptied at least once per week or more often if necessary. 14. Include a timetable showing the periods of time required for the construction of the operation. Except for the internal roads that will be completely built per plan during initial site development, the buildings, bulk storage sites, and test sites will be built overtime. It is expected that only one of the warehouse/office buildings, one bulk storage area, and three of the test sites will be built in the initial phase of construction. Then an additional office/warehouse building, and one or two test sites will be added incrementally on demand and desired business operations. Below is a table representing the expected timeline for the improvements proposed under this USR.

Describe the proposed and existing lot surface type and the square footage of each type (i.e. asphalt, gravel, landscaping, dirt, grass, buildings). The existing site condition is as dryland pasture and one windmill for livestock water. The proposed site conditions are listed in the Land Use Table: RTF - Main Area • Office/Warehouse Buildings = 37,800 ft2 (4 @ 9,450 ft2 each) Concrete = 50,831 ft2 (12,708 ft2 per building) • Gravel = 153,265 ft2 (Entrance, around buildings) • Total Area = 241,896 ft2 RTF — Engine Testing Site (11 total) Testing Building = 1,200 ft2 • Concrete = 2,736 ft2 • Gravel = 12,884 ft2 (surrounding building) • 3-6" Rip -Rap = 25,000 ft2 (Slope Stabilization • Total Area per Testing Site = 41,820 ft2 RTF — Bulk Storage Site (2 total) Concrete = 8,000 ft2 (secondary containment, foundatio Gravel = 32,000 ft2 @ 40% +� Total Area per Bulk Site = 40,000 ft2 ns) RTF — Internal Road Network • Gravel (Light -Duty (16' wide), ^'10,200 If) = 163,200 ft2 • Gravel (Heavy -Duty (28' wide), ^ 2,710 If) = 75,880 ft2 • Total Area of Roads = 239,080 ft2 • Total Property Area = 17,319,9►98 ft2 (397.61 acres) 16. How many parking spaces are proposed? How many handicap -accessible parking spaces are proposed? 2 ADA parking stalls are proposed for each building. 34 additional standard parking stalls are proposed for each building, most of which are covered. 17. Describe the existing and proposed fencing and screening for the site including all parking and outdoor storage areas. The existing site fences consist of standard barbwire livestock fences. Due to the remoteness of the site, no screening fences are being proposed around the main structures. There are no publicly maintained roads near the site. Safety gates and fences will be installed around the testing pads. The testing pads are being proposed on the low laying areas of the site and are naturally screen from public view. Security fencing is proposed for the office/warehouse complex. 18. Describe the existing and proposed landscaping for the site. The existing site condition is dryland grass, no other landscaping exist on site. The proposed landscaping around the main structures, office and warehouse areas, is decorative rock or xeriscape. Outside watering may not be permitted with the commercial water well, the existing water well will be converted to commercial use, from the present ag well status, after approval of the USR. 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. At the cessation of the USR, all above ground piping will be removed from the site. All bulk storage fuel tanks will be removed from the site The 9,450 SQ-FT building could be used to support agricultural business operations, the test pad buildings could be used as livestock shelters or hay barns. The proposed on -site road network could be used to monitor livestock grazing the site. 20. Describe the proposed fire protection measures. Each rocket test pad will have a vegetation free zone. The size of the vegetation zone may vary from test pad to test pad. As the size of the rocket that is being tested increases, the vegetation zone will increase. The office/warehouse buildings are unable to be sprinkled because of their location. The office buildings occupancy groups are B and Si and qualify to be non -separated occupancies and meet allowable building area and height. The buildings will be a minimum of 60' apart. 10# ABC fire extinguishers will be provided and located per Fire Marshal. 21. Explain how this proposal is consistent with the Weld County Comprehensive Plan per Chapter 22 of the Weld County Code. ARTICLE 1! Principles, Goals, and Objectives Sec. 22-2-10. - Guiding principles. The following Guiding Principles are the foundation for land use policy in the County. All of the Goals and Objectives within the Weld County Comprehensive Plan are adopted with the intent that they are consistent with the Guiding Principles. A. Respecting Our Agricultural Heritage. Weld County has an agricultural heritage built upon the hard work of pioneers and farmers on traditional family farms. Weld County is now one of the most economically productive agricultural counties in the nation. The Weld County Right to Farm Statement and the Goals and Objectives in this Plan support the importance of agriculture in the County. In the past, the property has been used as dry land pasture. As it is dryland pasture, the property will only support 25 cows grazing on a year-round basis, as obtained from the present property owner. From the Web Soil Survey, the majority of the property is not prime farmland, 66.6%. The remaining 33.4% of the property is broken down into two different areas, 10.5% is classified as Farmland of Statewide Importance with the remaining 22.9% classified as Prime Farmland if irrigated and protected from flooding, there are no irrigation facilities on or near this property and the 22.9% area is primarily located in an un- published floodplain. The property would not be considered a highly productive agricultural property. The proposed site use will not impact the agricultural productivity of the surrounding properties. B. Respecting Private Property Rights. One of the basic principles upon which the United States was founded is the right of citizens to own and utilize property so long as that use complies with local regulations and does not interfere with or infringe upon the rights of others. The proposed site used is assembly and testing of small rocket engines used to control satellites in orbit. The proposed is grouped within the RESEARCH LABORATORIES which is permitted with an approved Use by Special Review. Please see the definition from Sec. 23-1- 90 as provided below. RESEARCH LABORATORY: A facility for scientific research in technology -intensive fields. Examples include, but are not limited to, biotechnology, pharmaceuticals, genetics, plastics, polymers, resins, coating fibers, films, heat transfer and radiation research facilities. This site has been chosen due to its remote location and Topographic features; thesite elevation changes are greater than 80 feet across the site. The closest residential home site is located 1.2 miles to the southeast with other homes in the surrounding area being at least 1.4 miles from the site. The rocket engine test pads are proposed in low laying areas of the site and the site topography will be used to dampen the sound generated during the rocket engine testing. Noise reports are being prepared or have been prepared by UMT's aerospace engineers. C Promoting Economic Growth and Stability. Land use policies have a significant impact on economic conditions in the County and should be structured to encourage economic prosperity. To ensure the continued strength of Weld county's economy, land use processes and decisions based on this plan shall be consistent and promote fiscally responsible growth. The proposed use would create a number of high paying jobs in Weld County. The present facilities of UMT are located in Berthoud, Colorado. Due the rapid growth of the Company, Ullrl'IT has outgrown the Berthoud facilities and needs more space. However, the Berthoud facility will remain in operation for some testing of rocket engines and as the company headquarters. The Ten (10) year plan, covered by this USR application, is for up to 80 employees at the Galeton site. As time progresses, the size of the rocket engines may increase. Beyond the Ten (10) year plan, the number of employees may exceed 100, at which time an Amended USR will be applied for to address the additional site uses. No public improvements to the existing maintained County Road system will be required. A slight increase in maintenance of WCR 78 from WCR 59 to WCR 63 may be required. WCR 63, North of WCR 78 is Weld County ROW per Road Viewer's Report at Reception No. 86028, recorded July 16, 1902. The present condition of this road is as an all-weather gravel road, wide single-track road, it is in very good condition. The mad is presently maintained by gas and oil companies. This roadway is located within the dedicated county ROW. It is proposed that this road be widened to accommodate the increased traffic loads as generated by the proposed development. The road improvements will be paid for and maintained by UMT. It is assumed that an agreement with the company that currently maintains the existing roadway will be obtained. The site is located in the 2016 Enterprise Zone as defined by the Weld County Property Portal. D. Protecting Health, Safety, and General Welfare. Land use regulations and policies will protect and enhance the health, safety, and general welfare of the citizens of Weld County. ARTICLE 1- General Provisions Sec. 23-1-40. - Purpose and intent. B. This Chapter is further intended to protect the public health, safety and welfare by: 1. Regulating activities and DEVELOPMENT in hazardous areas. The site of the proposed use is not located in a hazardous overlay district as defined the Weld County Information Portal or the airport overlay district. An un-published floodplain does exist on site. A detailed Floodplain Study has been preformed and the 100 -year floodplain has been defined. The proposed test stands have been placed outside of the floodplain and will adequately elevated to protect them from flooding and damage to sensitive equipment. 2. Protecting lands from activities which would cause immediate or foreseeable material danger to significant wildlife habitat and would endanger a wildlife species. The proposed use of the site is assumed to not affect any wildlife habitat or species. 3. Preserving areas of historical and archaeological importance. There are no known areas of historical or archaeological importance on this property. 4. Regulating, with respect to the establishment of, roads on public lands administered by the federal government; this authority includes authority to prohibit, set conditions for or require a permit for the establishment of any road authorized under the general right-of-way granted to the public by 43 U.S.C. 932 (R. S. 244 7) but does not include authority to prohibit, set conditions for or require a permit for the establishment of any road authorized for mining claim purposes by 30 U.S.C. 21 et seq., or under any specific permit or lease granted by the federal government. No public improvements to the existing maintained County Road system are required. A slight increase in maintenance of WCR 78 from WCR 59 to WCR 63 may be required, grading operations. WCR 63, North of WCR 78 is Weld County Right of Way (ROW), however this portion of road system is not maintained by Weld County. The present condition of this road is as an all- weather gravel road, wide single track. The road is presently maintained by gas and oil companies. This roadway is located within the dedicated ROW. 5. Regulating the location of activities and DEVELOPMENTS which may result in significant changes in population density. The proposed use does not affect the population density in area or at the site. 6. Providing for phased DEVELOPMENT of PUBLIC services and facilities. No new public services or facilities are required for the proposed use at the site. 7. Regulating the USE of land on the basis of the impact of land USE changes on the community or surrounding areas. This site has been chosen due to its remote location and Topographic features. The closest residential home site is located 1.2 miles to the southeast with other homes in the surrounding area being at least 1.4 miles from the site. The rocket engine test pads are proposed in low laying areas of the site and the site topography will be used to dampen the sound generated during the rocket engine testing. Noise reports are being prepared or have been prepared by UMT's aerospace engineers. 8. Otherwise planning for and regulating the USE of land so as to provide planned and orderly USE of land and protection of the environment in a manner consistent with constitutional rights. At this time, a Use by Special Review (USR) permit is in process for the proposed site use. 22. Explain how this proposal is consistent with the intent of the zone district in which it is located. (Intent statements can be found at the beginning► of each zone district section in Article Hi of Chapter 23 of the Weld County Code.) ARTICLE ill - Zone Districts Division I - A (Agricultural) Zone District Sec. 23-3-10. - intent. Agriculture in the COUNTY is considered a valuable resource which must be protected from adverse impacts resulting from uncontrolled and undirected business, industrial and residential land USES. The A (Agricultural) Zone District is established to maintain and promote agriculture as an essential feature of the COUNTY. The A (Agricultural) Zone District is intended to provide areas for the conduct of agricultural activities and activities related to agriculture and agricultural production, and for areas for natural resource extraction and energy development, without the interference of other, incompatible land USES. in the past, the property has been used as dry land pasture. As it is dryland pasture, the property will only support 25 cows grazing on a year-round basis, as obtained from the present property owner. From the Web Soil Survey, the majority of the property is not prime farmland, 66.6%. The remaining 33.4% of the property is broken down into two different areas, 10.5% is classified as Farmland of Statewide Importance with the remaining 22.9% classified as Prime Farmland if irrigated and protected from flooding, there are no irrigation facilities on or near this property, the 22.9% area is primarily located in an un-published floodplain. The property would not be considered a highly productive agricultural property. The proposed site use will not impact the agricultural productivity of the surrounding properties. 23. Explain how this proposal will be compatible with future development of the surrounding area or adopted master plans of affected m u nicipalities. This site has been chosen due to its remote location and Topographic features. The closest residential home site is located 1.2 miles to the southeast with other homes in the surrounding area being at least 1.4 miles from the site. The rocket engine test pads are proposed in low laying areas of the site and the site topography will be used to dampen the sound generated during the rocket engine testing.

Regulating activities and DEVELOPMENT in hazardous areas. The site of the proposed use is not located in a hazardous overlay district as defined the Weld County Information Portal or the airport overlay district. An un-published floodplain does exist on site. A detailed Floodplain Study has been performed and the 100 -year floodplain has been defined. The proposed test stands have been placed outside of the floodplain and will adequately elevated to protect them from flooding. No major changes to the existing un-published floodplain are proposed. An engineered low -flow crossing will be utilized when crossing the floodplain. 2. Protecting lands from activities which would cause immediate or foreseeable material danger to significant wildlife habitat and would endanger a wildlife species. The proposed use of the site is assumed to not affect any wildlife habitat or wildlife species. 3. Preserving areas of historical and archaeological importance. There are no known areas of historical or archaeological importance on this property. 4. Regulating, with respect to the establishment of, roads on public lands administered by the federal government, this authority includes authority to prohibit, set conditions for or require a permit for the establishment of any road authorized under the general right-of-way granted to the public by 43 I.S.C. 932 (R.S. 2447) but does not include authority to prohibit, set conditions for or require a permit for the establishment of any road authorized for mining claim purposes by 30 U.S.C. 21 et seq., or under any specific permit or lease granted by the federal government. No public improvements to the existing maintained County Road system is required. A slight increase in maintenance of WCR 78 from WCR 59 to WCR 63 may be required in the form of additional grading operations. WCR 63, North of WCR 78 is Weld County Right of Way (ROW), however this portion of the road system is not maintained by Weld County. The present condition of this road is as an all-weather gravel road, wide single track. The road is presently maintained by gas and oil companies. This roadway is located within the dedicated ROW. Future widening of this roadway may be required, an agreement with the present entity maintaining the roadway will need to be created and it will address who will pay for the improvements and future maintenance of the said roadway. It is not proposed that Weld County would maintain this roadway. 5. Regulating the location of activities and DEVELOPMENTS which may result in significant changes in population density. The proposed use does not affect the population density in area or at the site. 6. Providing for phased DEVELOPMENT of PUBLIC services and facilities. No new public services or facilities are required for the proposed use at the site. 7. Regulating the USE of land on the basis of the impact of land USE changes on the community or surrounding areas. This site has been chosen due to its remote location and the Topographic features of the site.

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 are no existing irrigation facilities on or near the site. In the past, the property has been used as dry land pasture. As it is dryland pasture, the property • ill only support 25 cows grazing on a year-round basis, as obtained from the present property owner. From the Web Soil Survey, the majority of the property is not prime farmland, 66.6%. The remaining 33.4% of the property is broken down into two different areas, 10.5% is classified as Farmland of Statewide Importance with the remaining 22.9% classified as Prime Farmland if irrigated and protected from flooding, there are no irrigation facilities on or near this property, the 22.9% area is primarily located in an un- published floodplain. The property would not be considered a highly productive agricultural property. The majority of the prime farm ground will remain as dryland grass, the office and warehouse buildings, as placed, do have a minor effect on the Farmland of Statewide Importance. 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 site of the proposed use is not located in a hazardous overlay district as defined the Weld County Information Portal or the airport overlay district. An un-published floodplain does exist on site. A detailed Floodplain Study has been performed and the 100 -year floodplain has been defined. The proposed test stands have been placed outside of the floodplain and will adequately elevated to protect them from flooding. 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. A Stormwater discharge permit, SWMP, as obtained from the Colorado Department of Environmental Health, will be required for site construction as the disturbed area will be greater than 1 AC. Upon approval of the USR, a SWMP permit, and associated maps will be provided to the project owner and/or site contractor, the responsible party will then apply for the said permit. An EPA Class V Wells for injection of Non -Hazardous Fluids into or Above Underground Sources of Drinking Water permit will need to be obtained for the septic building to serve more than 20 people. Permits from the Colorado Division of oil and Public Safety will also have to be obtained for the storage of the various fuels used on -site, boilers if used in the buildings, and a explosives permit. An Air Pollutant Emissions Notice (APEN) permit from the Colorado Department of Public Health & Environment will be required. USE BY SPECIAL REVIEW USR DEVELOPMENT REVIEW QUESTIONNAIRE Answer the following questions per Section 8-11-40, Appendix 8-Q, and Section 8-14-10 of the Weld County Code. Please type on a separate sheet. If a question does not pertain to your proposal, please respond with an explanation do not leave questions blank. 1. 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. WCR 63 Right -of -Way (ROW) extends to the property from WCR 78, but this stretch of WCR 63 is not maintained by Weld County* Access to the property is from WCR 63 through a barbed wire gate at the northwestern corner of the property, near where WCR 84 would be located. From there a wagon trail type road goes east to the water well and livestock water tank area. The office/warehouse buildings will be located near WCR 63 in the center of the western half of the subject property. Ursa Major wants to improve WCR 63, from WCR 78 to the proposed access, based on the current condition of WCR 63 and the needed service level for the expected traffic generated by the project. The existing gate from WCR 63 is at the very northwest corner of the property and will be removed with the development. The proposed access will be approximately 1/000 ft south of the existing gate. 2. Describe any anticipated change(s) to an existing access, if applicable. The existing gate from WCR 63 is at the very northwest corner of the property and will be removed with the development. The access is just unimproved wheel paths leading away from WCR 63 that will be reseeded with native prairie grass. 3. Describe in detail any existing or proposed access gate including its location. Existing —The existing gate is approximately 25' wide and made of barb wire with a tensioning latch. Proposed - A security gate will be constructed to control site traffic approximately 65 ft from the western edge of WCR 63 ROW which will allow for truck stacking during admittance. 4.

Describe the topography (using terms like flot, slight hills, steep hills, etc.) of the road in the vicinity of an existing or proposed access. VVith the exception of immediately around Coal Creek approximately 34 mile east of WCR 63, the area along WCR 63 from WCR 78 north to the subject property is relatively flat and open grasslands and crop fields. USE BY SPECIAL REVIEW (USR ENVIRONMENTAL HEALTH QUESTIONNAIRE Answer the following questions per the Weld county code, Chapters 14, 23 and 30. Please type on a separate sheet. If a question does not pertain to your proposal, please respond with an explanation — do not le a ve questions blank. 1. 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 permitted water well, Permit Number 153242-A, is located on one of the parcels under consideration for the proposed USR. The water well is presently classified as an agricultural water well used for the watering of livestock. Upon approval of the proposed USR, an application to convert the existing water well to a commercial well will be applied for. The well permit and a current Drawdown test have been attached. 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. Of 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.) There are no existing On -site Wastewater Treatment Systems (OWTS) on the site. The proposed sewage disposal method is OWTS. It is proposed that each OWTS will service two buildings, each build will accommodate 20 full-time employees. 3. if storage or warehousing is proposed, what type of items will be stored? Rocket engines will be stored in the warehouse building or test building during the pre-test and post - testing process and shipping preparation. The on -site tele-handlers and road maintenance equipment will be either parked outside near the test sites, office/ warehouse buildings, or in the equipment storage building once constructed. 4. Describe where and how storage and/or stockpile of wastes, chemicals, and/or petroleum will occur on this site. The proposed use will not generate any stockpiles of waste. No industrial waste stockpiles will be generated by the facility. Preventive maintenance fluids, motor oil, antifreeze, ect., will be stored on site to maintain the equipment used on site. These fluids will be stored in the warehouse area or a possible future equipment building. Diesel will be stored on site for the equipment used to support the site activities. It is assumed that 250 gallons will be adequate. The containment system will be dependent on the fuel tank provided by the fuel vendor, if a secondary containment tank is used, it will be free standing. If a single wall fuel tank is used, a containment system of at least 1.5 times the largest tank will be designed and placed at the fueling location. Jet "A" will be utilized for testing of some of the rocket engines. Bulk fuel storage areas have been denoted on the site plan. Tank sizing has not been determined at this time, vendor dependent. It is assumed that the Jet "A" fuel tank will have a secondary containment tank. S. If there will be fuel storage on site, indicate the gallons and the secondary containment. State the number of tanks and gallons per tank diesel will be stored on site for the equipment used to support the site activities. It is assumed that 250 gallons will be adequate. The containment system will be dependent on the fuel tank provided by the fuel vendor, if a secondary containment tank is used, it will be free standing. If a single wall fuel tank is used, a containment system of at least 1.5 times the largest tank will be designed and placed at the fueling location. Jet "A" will be utilized for testing of some of the rocket engines. Bulk fuel storage areas have been denoted on the site plan. Tank sizing has not been determined and dependent on the vendor. It is assumed that the Jet "A" fuel tank will have a secondary containment tank. A list of usage and known information is provided in the following tables. Bulk Tank Storage Sites The facility will be set up with two bulk storage areas that will house the large tanks and tub trailers for the various fuels and gases needed for the rocket engine testing. The bulk tanks will be connected to run tanks located at each test site via an internal network of pipes. The bulk storage sites will be located to provide ease of access for the large semi -trucks used to deliver the fuels, and centralized piping hubs for all the proposed testing sites. The roads to the bulk storage areas will be 26' wide heavy-duty gravel roads designed to accommodate fully loaded tanker trailers. Table 4.

If there will be washing of vehicles or equipment on site, indicate how the wash water will be contained. No washing of equipment is proposed on the site. 7. If there will be floor drains, indicate how the fluids will be contained. No floor drains are proposed in the warehouse areas. Floor drains may be utilized in the restrooms to aid in keeping the facilities clean, wastewater from these drains is considered as domestic wastewater. 8. indicate if there will be any air emissions (e.g. painting, oil storage, etc.). Emissions from our rocket engines are very clean and does not produce large quantities of particulate matter, oxides, or materials. like all combustion devices it does produce carbon dioxide and carbon monoxide. 9. Provide a design and operations plan if applicable (e.g. composting, landfills, etc.). The proposed facility will not be used for waste collection, recycling, or industrial processing of byproducts. Only pre-test assembly, inspections, and testing will be performed on -site. 10. Provide a nuisance management plan if applicable (e.g. dairies, feedlots, etc.). Ursa Mar utilizes concrete, boulders, and other natural methods to control dust in our rocket engine test stands. Due to limited availability, we cannot use water to control dust. The amount of internal traffic will be low and internal speed limits kept under 20 mph. Magnesium chloride will be used periodically to help reduce the level of dust generated by traffic on internal roads. The natural topography will be used along with cutting the testing sites into the hill sides to deflect noise. Noise Study will be p sided by Ursa Major based on the effects of the proposed grading and testing site locations. . Additional information may be requested depending on type of land use requested.

UNIT #6 EVANS, CO 80620 970-330-0308 General Location and Description The subject property is a combination of five parcels (Parcel #'s 071308200001, 071308200002, 071308200003, 071308200004, 0713082O0005), with a total area of 397.61 acres located approximately 10 miles northeast of Galeton, Colorado. The Reference the Property Vicinity Map in Figure 1 below. WCR 63 Right -of -Way (ROW) extends to the property from WCR 78, but this stretch of WCR 63 is not maintained by Weld County. The subject property is zoned Agriculture (AG), as are the majoring of the surrounding properties. There are multiple tank batteries for oil and gas production in the area as well. The closest residential structure is just over 1 mile away to the southeast of the southern most property boundary. The southern property boundary used to be ROW for WCR 82, however the ROW was vacated on April 6, 1959 (Reception No. 1301745). Long's Peak Dairy is approximately 2 miles west of the site, and a few farms are 2.5 miles to the north-northwest near Highway 14. The closest town with commercial services is Eaton, approximately 17 miles west of the subject property. Figure 1. Property Vicinity Map WebSoils Survey Based on information gather from the USGS Websoils Survey database, the site is mainly sandy loam and fine sandy loam with areas of Renohill-Shingle complex, reference Table 1 below for site soils descriptions. The hydrologic soils groups or the various soil types are A, B and D and the typical range of slope is 0% to 9%, however some areas going into the creek bed have higher slopes. The soils northwestern area of the subject property has the soils most favorable for septic system, and the soils found in the area are adequate for commercial/industrial building foundation systems. Within the creek bed the ground water may be seasonally higher based on regional precipitation leading to saturated and unstable soils with increased corrosion potential. Majority of the site is not prime farmland. Reference Figure 2 for a soils map with Farmland Classifications shown.

The subject property is approximately 5.3 miles north of Crow Creek along the Coal Creek tributary. Relatively close to the bottom of the contributing watershed, approximately 80 sq, miles drains to Coal Creek as it runs through the subject property. A FEI IA Flood Panel is not published for Coal Creek, Panel No. 08123C1300E, but it is a major drainage way and floodplain between the Pawnee National Grasslands (also unpublished) and Crow Creek, which is a published floodplain, Panel No. 08123C1600E. Since most of the Coal Creek watershed is the Pawnee National Grasslands, it is likely that FEMA did not map floodplains in the area since little to no development was expected besides irrigated farms and grazing land. The unpublished floodplain in Coal Creek was analyzed, within the boundaries of the subject property, to determine the boundaries of the 100 -year (1% probability) storm flows expected to protect sensitive testing equipment from flood damage. Reference Figure 3 below for an image of the 100 -year floodplain (purple hatched area) on the subject property.

Coal Creek 100-yr Floodpiain Boundary Proposed Development The proposed facility will include (4) four 9,450 ft2 warehouse/office buildings, (2) two chemical/fuel bulk storage locations, and up to (11) eleven 45,000 ft2 rocket engine test sites each containing a 1,200 ft2 test building. An internal road network will be constructed connecting the various sites via an all- weather gravel surface capable of handling the expected vehicle loads. The site will be accessed via WCR 63 along the western edge of the property near the proposed office/warehouse buildings. The facility will be built out over time with the initial phase of construction only including items planned on the west side of Coal Creek. It is expected that only one of the warehouse/office buildings, one bulk storage area, and three of the test sites will be built in the initial phase of construction.

UNIT #6 EVANS, CO 80620 970-330-0308 The main area will be designed so all generated runoff flows directly east into Coal Creek via a network of swales and culverts. Concrete channels, valley pans, and sedimentation basins will be used as necessary to reduce chronic erosion problems around the building, and as the main area runoff is concentrated into swales. The grading design will utilize natural topography as much as possible to direct all generated runoff directly into Coal Creek. The main area will receive up to 3 ft of fill to create positive drainage away from the buildings and direct runoff east towards Coal Creek. There are various minor draws (runoff concentrating geography) identified throughout the subject property run down the banks of the Coal Creek basin. Test sites have been laid out along the banks to ALLES TAYLOR & DUKE, LLO LICENSED PROFESSIONAL ENGINEERS LICENSED PROFESSIONAL LAND SURVEYORS 3610 35TH AVE. UNIT #6 EVANS, Co 80620 970-330-0308 avoid sitting in one of these draws and blocking natural drainage patterns, and culverts are planned at each internal road crossing. Most of the draws will not experience heavy runoff concentrations due to a multitude of naturally occurring local ridges and flow lines creating numerous flow paths and sheet flow areas. As such one of the larger tributary areas to the draws was identified and the expected runoff calculated, along with a range of slopes in the different draws, to determine that a 15" diameter common culvert size would suffice at all road crossings. The culverts will vary in material depending on the expected traffic (heavy-duty or light -duty), corrosion concerns, and pipe availability. Each culvert crossing will include concrete head walls at the inlet and outlet of the pipe and soil filled rip -rap erosion protection to prevent damage to the draws and the internal road network. The testing sites will be dispersed along the banks of the Coal Creek for sound attenuation purposes, and the bulk storage will be as centrally located relative to the testing sites as possible for the piping layout. As such, these sites will sit in the areas of the property with the highest relative slopes by being cut into the hill side. The sites will be graded such that the main working area of each site is uniformly graded at a 1-2% grade downhill. From the edge of the working area the uphill slopes will be cut back to a typical slope of 5:1 (20%). This area will be covered with a large diameter rip -rap for erosion protection. A maximum height on the fill embankment of 2' will be used to establish the relative elevation of the site relative to the native grades, and the fill embankment planned on the downslope sides of the bulk storage testing sites will be erosion protected by soil filled rip -rap. Coal Creek Floodplain Analysis A model of Coal Creek was created by ATD based on an AutoCAD Civil 3D surface created by Faber Engineering using aerial LiDAR topographic survey methods. The topographic data was imported into HEC-RAS-Version 6.1 as raster data to create a model of the terrain across the subject property using RAS Mapper, see Figure 4 below. The topographic data was converted into raster data by calculating the average elevation of every 3'x3' square due to the size of the surface data (>400 acres at LiDAR accuracy). Based on the level of detail retained in the HEC-RAS geometry data and resulting calculations, the data resolution chosen does not significantly change the results of the flood analysis. 8 ALLIES TAYLOR & DUKE, LLC LICENSED PROFESSIONAL ENGINEERS LICENSED PROFESSIONAL LAND SURVEYORS 3610 35TH AVE.

Peak flows within the Coal Creek were obtained from the USGS StreamStats website and printouts are included in Appendix B of this narrative. Three different locations within the subject property were selected within the StreamStats interactive map to calculate peak flow data for Coal Creek that would accurately represent the flow rates within the property, and changes in flow rates as Coal Creek runs through the property. The locations selected included one near the northern property line, one at the junction with a major tributary in the middle of the property, and one near the southern property line.

Stormwater Detention Exception Per Weld County Code Chapter 8, Article XI -Storm Drainage Criteria, section 8-11-40(I), stormwater detention will not be required for sites that meet any one of the (14) fourteen conditions listed. In our opinion, the subject property meets condition No. 11 based on the Coal Creek floodplain being on the floodplain. 11. An indivrdual parcel with an unobstructed flow path and no other parce!(s) between the Federal Emergency Management Administration (FEMA) regulatory floodplain channel and the project. The code states FEMA regulatory floodplain channel however, the Firm panel for the subject property is not published due to the largely undeveloped and undevelopable pa ble land within the Coal Creek watershed. Mainly due to the Pawnee National Grasslands (Federal property) making up a large portion of the Firm panel. Adjacent panels containing portions of the grasslands are also unpublished. Based on our analysis of the Coal Creek watershed, a floodplain does exist on the subject property. The estimated runoff generated by the proposed 2.5% increase in overall property imperviousness is insignificant compared to the total expected peak flows within Coal Creek and will not have a noticeable impact on the properties downstream of the site. The subject property is also not within an established MS4 area and ALLES TAYLOR & DUKE, LLC LICENSED PROFESSIONAL ENGINEERS LICENSED PROFESSIONAL LAND SURVEYORS 3610 35TH AVE. UNIT #6 EVANS, CO 80620 970-330-0308 is not upstream of any urbanized or urbanizing areas, and therefore meets the intent of this code exception. Construction BMWs Construction Best Management Practices (BMP's) will be utilized to control sediment travel and construction debris during grading operations on -site. Silt fencing will be installed around each test site, bulk storage, and the main area, prior to clearing and grubbing begins, to control sediment travel and mitigate fugitive dust during grading operations. The silt fence will remain in place until final stabilization is complete. Straw wattles will be used along the road disturbed areas, in the draws, and downstream of disturbed areas on the sloped portions of the site. The wattles will remain in place until permanent seeding can be established along the roads. Final stable ground cover will be achieved with compacted gravel road base and concrete within the main area, test sites, and roadway. All adjacent area disturbed during construction activities will be hydroseeded with a grass mixture like the native grasses present on the site. The maximum slope expected for cut or fill embankments is 4:1, but if the slope is exceeded in any areas Reinforced Turf Matting (RTM) will be installed immediately after final grading is achieved to aid in establishing permanent seeding. Permanent BMP's will be designed at the inlet and outlet of culverts. Soil -filled rip -rap rundowns with sedimentation ponds will be designed for all culvert outlets, and headwalls will be used to prevent piping and undermining from flows entering and existing the culverts.

The ratings are both verbal and numerical. Rating class terms indicate the extent to which the soils are limited by all of the soil features that affect these uses. Not limited indicates that the soil has features that are very favorable for the specified use. Good performance and very low maintenance can be expected. Somewhat limited indicates that the soil has features that are moderately favorable for the specified use. The limitations can be overcome or minimized by special planning, design, or installation. Fair performance and moderate maintenance can be expected. Very limited indicates that the soil has one or more features that are unfavorable for the specified use. The limitations generally cannot be overcome without major soil reclamation, special design, or expensive installation procedures. Poor performance and high maintenance can be expected. Numerical ratings in the table indicate the severity of individual limitations. The ratings are shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations between the point at which a soil feature has the greatest negative impact on the use (1.00) and the point at which the soil feature is not a limitation (0.00). Septic tank absorption fields are areas in which effluent from a septic tank is distributed into the soil through subsurface tiles or perforated pipe. Only that part of the soil between depths of 24 and 72 inches or between a depth of 24 inches and a restrictive layer is evaluated. The ratings are based on the soil properties that affect absorption of the effluent, construction and maintenance of the system, and public health. Saturated hydraulic conductivity (Ksat), depth to a water table, ponding, depth to bedrock or a cemented pan, and flooding affect absorption of the effluent. Stones and boulders, ice, and bedrock or a cemented pan interfere with installation. Subsidence interferes with installation and maintenance. Excessive slope may cause lateral seepage and surfacing of the effluent in downslope areas. Some soils are underlain by loose sand and gravel or fractured bedrock at a depth of less than 4 feet below the distribution lines. In these soils the absorption field may not adequately filter the effluent, particularly when the system is new. As a result, the ground water may become contaminated. Sewage lagoons are shallow ponds constructed to hold sewage while aerobic bacteria decompose the solid and liquid wastes. Lagoons should have a nearly level floor surrounded by cut slopes or embankments of compacted soil. Nearly impervious soil material for the lagoon floor and sides is required to minimize seepage and contamination of ground water. Considered in the ratings are slope, saturated hydraulic conductivity (Ksat), depth to a water table, ponding, depth to bedrock or a cemented pan, flooding, large stones, and content of organic matter. USDA Natural Resources Web Soil Survey Conservation Service National Cooperative Soil Survey 2117/2022 Page 1 of 3 Sewage Disposal --Weld County, Colorado, Northern Part Saturated hydraulic conductivity (Ksat) is a critical property affecting the suitability for sewage lagoons. Most porous soils eventually become sealed when they are used as sites for sewage lagoons. Until sealing occurs, however, the hazard of pollution is severe. Soils that have a Ksat rate of more than 14 micrometers per second are too porous for the proper functioning of sewage lagoons. In these soils, seepage of the effluent can result in contamination of the ground water. Ground -water contamination is also a hazard if fractured bedrock is within a depth of 40 inches, if the water table is high enough to raise the level of sewage in the lagoon, or if floodwater overtops the lagoon. A high content of organic matter is detrimental to proper functioning of the lagoon because it inhibits aerobic activity. Slope, bedrock, and cemented pans can cause construction problems, and large stones can hinder compaction of the lagoon floor. If the lagoon is to be uniformly deep throughout, the slope must be gentle enough and the soil material must be thick enough over bedrock or a cemented pan to make land smoothing practical. Information in this table is intended for land use planning, for evaluating land u s e alternatives, and for planning site investigations prior to design and construction. The information, however, has limitations. For example, estimates and other data generally apply only to that part of the soil between the surface and a depth of 5 to 7 feet. Because of the map scale, small areas of different soils may be included within the mapped areas of a specific soil. The information is not site specific and does not eliminate the need for onsite investigation of the soils or for testing and analysis by personnel experienced in the design and construction of engineering works. Government ordinances and regulations that restrict certain land uses or impose specific design criteria were not considered in preparing the information in this table. Local ordinances and regulations should be considered in planning, in site selection, and in design. Report Sewage Disposal [onsite investigation may be needed to validate the interpretations in this table and to confirm the identity of the soil on a given site. The numbers in the value columns range from 0.01 to 1.00. The larger the value, the greater the potential limitation. The table shows only the top five limitations for any given soil.

Hydrologic soil group is a group of soils having similar runoff potential under similar storm and cover conditions. The criteria for determining Hydrologic soil group is found in the National Engineering Handbook, Chapter 7 issued May 2007(http://directives.sc.egov.usda.gov/OpenNonWebContent.aspx? content=17757.wba). Listing HSGs by soil map unit component and not by soil series is a new concept for the engineers. Past engineering references contained lists of HSGs by soil series. Soil series are continually being defined and redefined, and the list of soil series names changes so frequently as to make the task of maintaining a single national list virtually impossible. Therefore, the criteria is now used to calculate the HSG using the component soil properties and no such national series lists will be maintained. All such references are obsolete and their use should be discontinued. Soil properties that influence runoff potential are those that influence the minimum rate of infiltration for a bare soil after prolonged wetting and when not frozen. These properties are depth to a seasonal high water table, saturated hydraulic conductivity after prolonged wetting, and depth to a layer with a very slow water transmission rate. Changes in soil properties caused by land management or climate changes also cause the hydrologic soil group to change. The influence of ground cover is treated independently. There are four hydrologic soil groups, A, B, C, and O, and three dual groups, ND, B/D, and CID. In the dual groups, the first letter is for drained areas and the second letter is for undrained areas. The four hydrologic soil groups are described in the following paragraphs: 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. Depth to the upper and lower boundaries of each layer is indicated. USDA Natural Resources Web Soil Survey a Conservation Service National Cooperative Soil Survey 2/17/2022 Page 1 of 6 Engineering Properties ---Weld County, Colorado, Northern Part Texture is given in the standard terms used by the U.S. Department of Agriculture. These terms are defined according to percentages of sand, silt, and clay in the fraction of the soil that is less than 2 millimeters in diameter. "Loam," for example, is soil that is 7 to 27 percent clay, 28 to 50 percent silt, and less than 52 percent sand. If the content of particles coarser than sand is 15 percent or more, an appropriate modifier is added, for example, "gravelly." Classification of the soils is determined according to the Unified soil classification system (ATM, 2005) and the system adopted by the American Association of State Highway and Transportation Officials (AASHTO, 2004). The Unified system classifies soils according to properties that affect their use as construction material. Soils are classified according to particle -size distribution of the fraction less than 3 inches in diameter and according to plasticity index, liquid limit, and organic matter content. Sandy and gravelly soils are identified as GW, GP, GM, GC, SW, SP, SM, and SC; silty and clayey soils as ML, CL, CAL, CH, and OH; and highly organic soils as PT. Soils exhibiting engineering properties of two groups can have a dual classification, for example, CL -ML. The AASHTO system classifies soils according to those properties that affect roadway construction and maintenance. In this system, the fraction of a mineral soil that is less than 3 inches in diameter is classified in one of seven groups from A-1 through A-7 on the basis of particle -size distribution, liquid limit, and plasticity index. Soils in group A-1 are coarse grained and low in content of fines (silt and clay). At the other extreme, soils in group A-7 are fine grained. Highly organic soils are classified in group A-8 on the basis of visual inspection. If laboratory data are available, the A-1, A-2, and A-7 groups are further classified as A -1-a• A b, A-2-4, A-2-5, A-2-6, A-2-7, A-7-5, or A-7-6. As an additional refinement, the suitability of a soil as subgrade material can be indicated by a group index number. Group index numbers range from 0 for the best subgrade material to 20 or higher for the poorest. Percentage of rock fragments larger than 10 inches in diameter and 3 to 10 inches in diameter are indicated as a percentage of the total soil on a dry -weight basis. The percentages are estimates determined mainly by converting volume percentage in the field to weight percentage. Three values are provided to identify the expected Low (L), Representative Value (R), and High (H). Percentage (of soil particles) passing designated sieves is the percentage of the soil fraction less than 3 inches in diameter based on an ovendry weight. The sieves, numbers 4, 10, 40, and 200 (USA Standard Series), have openings of 4.76, 2.00, 0.420, and 0.074 millimeters, respectively. Estimates are based on laboratory tests of soils sampled in the survey area and in nearby areas and on estimates made in the field. Three values are provided to identify the expected Low (L), Representative Value (R), and High (H). Liquid limit and plasticity index (Atterberg limits) indicate the plasticity characteristics of a soil. The estimates are based on test data from the survey area or from nearby areas and on field examination. Three values are provided to identify the expected Low (L), Representative Value (R), and High (H). References: American Association of State Highway and Transportation Officials (AASHTO). 2004.

Roads Background Aerial Photography The soil surveys that comprise your AOl were mapped at 1:24,000. Warning: Soil Map may not be valid at this scale. Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and accuracy of soil line placement. The maps do not show the small areas of contrasting soils that could have been shown at a more detailed scale. Please rely on the bar scale on each map sheet for map measurements. Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required. This product is generated from the USDA-NRCS certified data as of the version date(s) listed below. Soil Survey Area: Weld County, Colorado, Northern Part Survey Area Data: Version 16, Aug 312 2021 Soil map units are labeled (as space allows) for map scales 1:50,000 or larger. Date(s) aerial images were photographed: Jul 19, 2018 —Aug 1O, 2018 The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident.

UNIT #6 EVANS, CO 80620 970-330-0308 Per the Galeton-Rocket Test Facility Noise Study provided by Ursa Major Technologies, Inc., the calculated noise levels produced by a Ripley (50 kip thrust) engine exceeds the maximum permissible noise level for an industrial land use, 80-90 dBA, per Weld County Code Chapter 14, Article IX, Section 14-9-40(B) & (C). Using conservative estimates for the effect of passive sound mitigation, the expected levels will be 90-100 dBA within 1,000 feet of the north, east, and south property lines of the subject property. Due to the shape of the property and proposed location of the rocket test stands within the Coal Creek channel, the sound levels at existing County Right -of -Way does not exceed the limits set by Weld County Code. All property immediately around the subject property is unoccupied farm field and grazing land with several oil & gas well sites. The nearest neighbor is approximately 1.2 miles south of the southern property line, and the expected noise level at this property will be equivalent to or lower than a passenger car on a nearby road, 70 dBA or less. Based on the topography and remoteness of the subject property, the noise generated by the proposed rocket test facility will not create a dangerous environment for people or livestock. Rocket testing is conducted over relatively short durations throughout the day and will not create a constant disturbance for neighbors. Weld County Code section 14-9-60 provides specific land uses that are exempt from Article IX, Chapter 14. A rocket engine test facility is an uncommon use that was not anticipated by current codes but is similar to and creates equivalent or lower noise levels for their neighbors than land uses listed in section 14-9-60. Below is a list of the allowed exceptions that are comparable to the proposed rocket engine testing facility. C. Any noise made during the operation of aircraft or other activities which are preempted by federal law, with respect to noise control. H. Any noise related to the use of property for the purposes of conducting speed or endurance events involving motor or other vehicles, but only where such use has been authorized by resolution, variance permit or nonconforming use authorized by the political subdivision or governmental agency having jurisdiction to authorize such use, and only during the specific period of time that such use is authorized. L Any noise produced in the course of normal mining operation or oil and gas exploration, drilling and production. Ursa Major chose the subject property due the remote location and topography being ideal for mitigating sound created by the testing rocket engines.

PROPRIETARY Introduction Ursa Major is a manufacturer of rocket engines based in Berthoud, Colorado with approximately 180 employees at the time this report was generated. Ursa's current products include Hadley, a 5 kip rocket engine designed for small space launch vehicles and hypersonic test beds, and Ripley, a 50 kip rocket engine designed for small and medium sized space launch vehicles. A kip is equivalent to 1z a short -ton of force. These two products utilize Liquid Oxygen as the oxidizer and JET -A/R P-1 (refined kerosene derivatives) as the fuel. Contextually, these engines are relatively small compared to other engines being flown today. Engines from other companies, such as SpaceX Blue Origin, produce between 200 and 500 kip of thrust. Ursa Major's test facilities are remotely operated from a control center during hazardous operations and are de- signed with numerous fail -safes, fire safety systems, and egress routes to minimize hazards to Ursa Major person- nel. Additionally, all test operations staff undergo a minimum of 90 days training on Ursa Major test systems. The proposed Galeton-Rocket Test Facility location was chosen specifically due to its topology and distance to neighboring residences. Rocket engine noise is highly directional when tested in a horizontal orientation and is a low frequency noise. The noise typically is highest along two lines each 60 degrees off the rocket's exhaust plume, forming a"butterfly" shape which can be seen in later figures, such as Figure 5. This means that behind and directly in front of the rocket engine see much lower noise levels and the maximum amplitude can be aimed to further mitigate sound levels via attenuation and deflection. The steep inclines along the Coal Creek stream bed provide ample opportunities for such noise attenuation and deflection. While the low frequency noise waves will travel longer distances than high frequency noises, the distance and directionality of the proposed Galeton-Rocket Test Facility test stands means that noise levels near residential homes should be equivalent to or lower than a pas- senger car on a nearby road, as noted in Table 2. Design Criteria The daytime and nighttime Weld Co u my maximum permissible noise levels, per Section 14-9-40 of the Charter and County Code, are summarized by receptor property land use in table below.

Weld county maximum permissible noise levels Land Use Daytime Night Time (7:00 a.m. to 9:00 p.m.) (9:00 p.m. to 7:00 a.m.) Residential or Commercial Industrial Avon -specified 55 d BA 50 d BA 90 dBA 75 dBA L 55 d BA 50 d BA Each test stand typically only performs two to three tests per day. The test duration is less than 15 minutes per one hour period. Testing is predominately performed during daytime hours and weekdays. Properties nearest to the site appear to all be zoned as residential or agricultural, therefore the daytime "Residential or Non -specified" land use classification applies. Per Section 14-9-40, Item C of the Charter and County Code: "Between the hours of 9:00 p.m. and 7:00 a.m., the noise levels set forth above may be exceeded by up to ten (10) decibels for up to fifteen (15) minutes in a one -hour period." Ursa Major suspects that the time interval is a misprint, other noise ordinances including the Colorado Noise Stat- ute allow for exceeds noes during daytime hours only. The Ursa Major analysis in the following sections of this 4 URSA MAJOR TECHNOLOGIES INC. PROPRIETARY report assumes that the 10 dB variance for short-term noise events applies to daytime hours, so the maximum daytime level would be 65 dBA. The proposed engine test sites will be 40,000 ft2 areas scattered throughout the property along the banks of Coal Creek. The sites are setback 600 ft from the exterior property lines, other test sites, and bulk storage areas for safety with enough space for nine possible locations within the subject property. The engine testing will be done in a test control building, approximately 1,200 ft2, situated on a concrete pad in the center of the test site and directed towards the uphill side of the slopes. The test stands will be situated within the buildings so the engine exhaust cone (noise source) is just inside the uphill face of the building firing through a 16 ft wide door. On average one test stand can perform 5 tests per twelve-hour workday. Each test takes anywhere from 5 seconds to 5 minutes to conduct with several hours needed for test preparation and breakdown. Each test site will be contin- uously operating during business hours for a total of 20-30 minutes of actual rocket engine firing per site. Testing is only performed Monday through Friday, 8 am to 6 pm, with some Saturday operations. Equivalent Noise Levels Rocket engine noise levels beyond the property line of Ursa major are going to be akin to lines five and six of Table 2. At the nearest neighbor, as previously noted, the sound level is likely to be much lower and equivalent to a car passing on a nearby road. Table 2.

Similarly, 105-110 dBA. can cause hearing loss in the human ear after 5 minutes. Ursa Major's predicted sound levels at the property line are "490 dBA, which can cause hearing loss in the human ear after 50 minutes of continuous exposure. (Center for Disease Control, 2019) Test Orientation Overview Ursa Major currently tests engines in a horizontal or near horizontal configuration. The notation of "horizontal" and "vertical" testing will be used continuously throughout the rest of this report. An example of a horizontal test stand and a vertical test stand is shown in the figure below. URSA MAJOR TECHNOLOGIES INC. PROPRIETARY Figure 1. Ursa Major's Hadley Engine in a Horizontal Position (left) and an Aerojet Rocketdyne RS -25 engine in a Vertical Position (right) The resulting sound pattern for vertical test stands is typically a circular pattern, compared to the previously de- scribed "butterfly" pattern. For the purposes of this noise study, both horizontal and vertical test positions were evaluated for sound levels. Active & Passive Sound Suppression Overview Due to Colorado's naturally dry climate, horizontal rocket engine testing is preferred to minimize or eliminate the need for high volume flow water systems for structural cooling and active sound suppression. Active sound sup- pression techniques can be somewhat effective, but all require large quantities of water. For a typical 50 kip thrust rocket engine, the required water is approximately 10,000 gallons per minute of testing. For a typical test day, an active suppression system could use up to 100,000 gallons of water which is the maximum annual allotment for one commercial water well. Passive sound suppression includes berms, utilizing natural topography, and other sound deflection and attenua- tion structures. Passive sound suppression often provides a more effective means of sound attenuation and knock- down compared to active methods. Berms operate by diffracting and disrupting the sound as it travels across a barrier. This is illustrated well in the figure below, taken from Noise Control Earth Berms (Highway Engineering Branch, 1997), which shows how sound is diffracted and reduced behind a noise barrier.

Fundamental Noise Barrier Concepts, from "Noise Control Earth Berms" 6 URSA MAJOR TECHNOLOGIES INC. PROPRIETARY Similarly, topography can diffract and reduce sound, though the shadow zone may be shallower than an elevated berm. The key element for barrier effectiveness is ensuring that the system's peak is as close to the source of the noise as possible. This is again illustrated in a figure in Noise Control Earth Berms, shown below: EXTRA PATH LENGTH = 0,6rn INSERTION LOSS = 13 Od B 3" & EXTRA PATH LEN GT IH i= O,i4 rrt iNsERTioit4 LOSS 1 1.5dB Figure 3.

PROPRIETARY Ripley Block 1 Estimated Sound Levels The Ripley sound levels were predicted using a NASA toolset called "RUMBLE!' More details on the provided in- puts can be found in Appendix 1— RUMBLE 2.0 Inputs. Rocket engine noise generation is controlled by the geom- etry of the engine, the thrust level of the engine, and the speed of the rocket plume exhaust. These properties are fed into the RUMBLE software, which generates a dBA contour plot. Additionally, only the altitude of the test site is taken into consideration in the RUMBLE model. Topography, pas- sive mitigations, and active mitigations are not accounted for. Mitigations are applied to the generated contours after running the model, but topography is not included in the analysis provided in this report. A table of the general results is shown below in Table 3. The chosen sound levels are point of hearing loss (105 dBA), the maximum allowable with no hearing loss (95 dBA), the expected sound level at the nearest neighbor (75 dBA), and the distance to residential allowable (55 dBA). Table 3. Estimated Sound Levels and Distances for Ripley Engine with no mitigations Sound Level [dBAJ 105 95 75 55 Horizontal Min. Dist. Horizontal Max. Dist.

For horizontal test positions, there is a minimum distance which is directly downstream of the engine plume and a maximum distance which is at the tips of the "butterfly" wing pattern. For a vertical stand, sound is distributed evenly in a circle. Note that for horizontal test positions, while sound levels can be higher further than a vertical stand, the affected area is much smaller than a vertical test stand. URSA MAJOR TECHNOLOGIES INC. PROPRIETARY Galeton-Rocket Test Facility Sound Mapping Overview The sound mapping was accomplished by generating a 20x20 point grid, spaced 0405 nautical miles (nmi), covering an area of 1 square nmi total. This sets the resolution for the following decibel contours, providing 400 calculation points within the 1 nmi square grid. The resulting contours were overlayed on the topography map was provided in the flood report generated by Alles, Taylor & Duke LLC. This map is shown in Figure 4. %Vt. 0E1/rg=I: 1onM lb[. le wig; sTYlllb r, Fen WS OrlIUS[IIS l ' i t r' minty' 3,a3 re— r' / - - Worn nefW1%1 ar3A'aw+ �'5 i, t _. 1:'V.f" I, I1 5 5 ♦ 1.1C[a MP LL isle: I • ti xl • -' 'y 1 ; • f oti rel: ♦ y� 4 ti x f f I.

The vertical stand produces slightly more noise, if unmitigated, in an equidistant circle. The im- age above shows the result assuming there is zero impact on the sound levels from topography or any other mitigation efforts such as sound berms/walls or flame buckets. The latter item would greatly reduce noise by deflecting sound near the source but requires active water cooling. 11 URSA MAJOR TECHNOLOGIES INC. PROPRIETARY Sound Estimates with passive Mitigation Passive mitigation for sound would include berms on three sides and locating the stand near a sharp rise in the topography. Site 3 was chosen as the example for this document, but most sites are located near the start of a shift in topography to accommodate this desire.

(Highway Engineering Branch; 1997) 12 URSA MAJOR TECHNOLOGIES INC. PROPRIETARY Note on Active Mitigation Active sound mitigations, namely in the form of water suppression, have been shown to provide 3-5 dBA of further sound reduction. (NASA, 1971) However, it is important to note that passive systems, as previously stated, can provide mitigation of 10 dBA or more. This means active suppression is at best half as effective as passive mitiga- tion. Additionally, as noted on Page 6 (Active & Passive Sound Suppression Overview), the water requirements for such an active system will exceed the annual allowable withdrawal from a single well in a single, typical day of use by Ursa Major. Active mitigations are therefore become impractical due to their relatively worse performance and incredibly high demand for water. 13 URSA MAJOR TECHNOLOGIES INC. PROPRIETARY Nearest Neighbor Ursa Major's proposed site is remotely located relative to local housing and other infrastructure. The figure below depicts the site boundary of Ursa Major's proposed site (orange), a 4 mile by 4 mile square (inner) and a 10 mile by 10 mile square (outer). All known houses are noted in red, all oil/industrial sites are marked in pink, and other sources of nearby noise are marked in blue. The nearest houses, to the south, are approximately 1.25 miles from the site border. Y. 51 Figure 9. Map noting UM proposed site and local houses and infrastructure Pawnee.

Horizontal test stand pointing 20 deg N -E The final orientation of the stand will be chosen to mitigate, diffract, and dampen as much of the sound as possible utilizing both passive mitigations, including berms, and the natural topography. The expected sound reduction is expected to be at least 10 dBA from the included berms alone. Additional sound attenuation is expected from the topography of the land, but that analysis is beyond the scope of Ursa Major's sound models. 15 URSA MAJOR TECHNOLOGIES INC. PROPRIETARY Verification & Monitoring Ursa Major has previously utilized both internal and external resources to evaluate, map, and then mitigate sound levels at its Berthoud test site. Accurate sound maps, both local and at the property line, were obtained using calibrated microphones. An external party, ATA Engineering, was used to verify Ursa Major predictions and models of sound. The results of this external party's measurements are in work at the time of writing this report, but preliminary results show that the RUMBLE model is a slightly conservative predictor of actual sound levels. ATA engineering is also developing a separate model of sound levels to determine passive mitigation height and relative distance that will improve upon Ursa Major's ability to attenuate sound from rocket engine testing. Ursa Major anticipates repeating this verification and monitoring procedure at all future sites. 16 URSA MAJOR TECHNOLOGIES INC.

UNIT #6 EVANS, CO 80620 970-330-0308 General Location and Description The subject property is a combination of five parcels (Parcel #'s 071308200001, 071308200002, 071308200003, 071308200004, 071308200005), with a total area of 397.61 acres located approximately 10 miles northeast of Galeton, Colorado. The five parcels will be combined into one parcel after USR approval is obtained. Reference the Property Vicinity Map in Figure 1 below. The property is currently used as pastureland for cattle and is encompassed and divided up by barbed wire fencing. Native prairie grasses and sage brush cover most of the lot, and on the steeper banks of Coal Creek the ground is bare. There is also a water well, Colorado Division of Water Resources Well Permit 153242-A dated January 30, 1989, in the northern center of the combined parcels that is pumped by a windmill into a livestock water tank. No other irrigation equipment is used on the property. V'VCR 63 Right -of -Way (ROW) extends to the property from WCR 78, hut this stretch of WCR 63 is not maintained by Weld County. Access to the property is from WCR 63 through a barbed wire gate at the northwestern corner of the property, near where WCR 84 would be located. From there a wagon trail type road goes east to the water well and livestock water tank area. Overhead electrical and telephone lines run past the subject property along the west side of WCR 63, and a 20' ROW Easement for Poudre Valley Rural Electrical Association, dedicated October 15, 2013, at Reception No. 3970907, extends east ofWCR 63, where WCR 82 would be, to the eastern property line of the subject property. Several underground gas and oil lines run parallel to the electrical ROW Easement in a 30' wide Pipeline Easement, dedicated November 13, 2012, at Reception No. 3970907 that overlaps the electrical easement, to the well site just east of the subject property.

UNIT #6 EVANS, Co 80620 970-330-0308 Surrounding Land Uses The subject property is zoned Agriculture (AG), as are the majoring of the surrounding properties. There is multiple well sites for oil and gas production on all sides of the subject property and dispersed throughout the immediate vicinity. The closest residential structure is just over 1mile away to the southeast of the southernmost property boundary, with a light density of houses on large lots dispersed along WCR 63 and WC R 65 from here to Highway 392. The southern property boundary used to be ROW for VVCR 82, however the ROW was vacated by Weld County on April 6, 1959 (Reception No. 1301745). Long's Peak Dairy is approximately 2 mile west of the site, and the closest houses to the north are near Highway 14, 2.5-3 miles away. All surrounding land is used for agricultural related purposes, oil and gas wells, and private residences. A property 14 mile to the west has an active USR permit for a shooting range, MU5R13.0012, and at the northeast corner of WCR 61 & 78, approximately 2 miles southwest, there is a large livestock operation under another USR permit, I MUSR16-0009. North of the property is mainly farmland and the Pawnee National Grasslands. The northern area is largely uninhabited with few public roads until Highway 14 directly north approximately 3 miles of the northern property line. While there is now a diner and coffee shop in Galeton, the closest town with existing commercial services is Eaton, approximately 17 miles west of the subject property. UMT wants to expand their assembly and testing service capabilities to a location that won't disturb neighbors. The near 400 -acre property is in a sparsely populated area within Weld County and fits the company's criteria for the RTF project exactly. While the proposed land use is not agricultural in nature, the selected location allows for the industrial style use by UMT to cause the least amount of impact to existing residents, businesses, and livestock currently in the area. Proposed Development The proposed facility will include (4) four 9,450 ft2 warehouse/office buildings, (1) one 9,600 ft2 equipment storage building, (2) two chemical/fuel bulk storage locations approximately 40,000 ft2 each, and up to (9) nine 40,000 ft2 rocket engine test sites each containing a 1,200 ft2 test building. An internal road network will be constructed connecting the various sites via an all-weather gravel surface capable of handling the expected vehicle loads. The site will be accessed via WCR 63 along the western edge of the property near the proposed office/warehouse buildings. UMT wants to improve WCR 63, from WCR 78 to the proposed access, based on the current condition of \NCR 63 and the needed service level for the expected traffic generated by the project. We are planning to widen the road and provide a heavy- duty gravel road section with the proposed site development. WCR 63 ends at the northern section line where WCR 84 would be, and there is only a few well sites to west that use WCR 63 north of WCR 80 other than farmers. The facility will be built out over time with the initial phase of construction only including items planned on the west side of Coal Creek. It is expected that only one of the warehouse/office buildings, one bulk storage area, and three of the test sites will be built in the initial phase of construction. Then an additional office/warehouse building, and one or two test sites will be added incrementally depending on demand and desired business operations. Below is a table representing the expected timeline for the improvements proposed under this USR. 3 A T D 4' jI ALLES TAYLOR & DUKE, LL LICENSED PROFESSIONAL ENGINEERS LICENSED PROFESSIONAL LAND SURVEYORS Table 1.

Factors triggering future phases are dependent of business needs and may happen sooner or later than expected. Site Access WCR 63, North of WCR 78 is Weld County ROW per Road Viewer's Report at Reception No. 86028, recorded July 16, 1902, however this portion of road system is not maintained by Veld County. The present condition of this road is as an all-weather gravel road, wide single-track road, it is in very good condition. The road is presently maintained by gas and oil companies. This roadway is located within the dedicated county ROW. It is proposed that this road be widened to accommodate the increased traffic loads as generated by the proposed development. The road improvements will be paid for and maintained by UMT. It is assumed that an agreement with the company that currently maintains the existing roadway will be obtained. The office/warehouse buildings will be located near WCR 63 in the center of the western half of the subject property. The existing gate from WCR 63 is at the very northwest corner of the property, but the proposed access will be moved approximately 1,000 ft south of the existing gate to an area in the property more suited for central oversight of the facility. There are no other access points along WCR 63 at the time this USR was submitted. A security gate will be constructed to control site traffic approximately 65 ft from the western edge of WCR 63 ROW which will allow for truck stacking during admittance. From the proposed entrance to the nearest County maintained paved road, WCR 59 south of WCR 78, if approximately 4.8 miles. It is estimated that most traffic generated by the facility will be coming from UMT's headquarters in Berthoud. Since WCR 63 end 1,000 ft north of the proposed access all traffic will head south out of the site to WCR 78. From there vehicles will go west 2 miles to WCR 59, the closest paved road, and then south 2 miles to WCR 74. From WCR 74 both Highway 392 (east 5 miles) and Highway 85 (west 10 miles) can be directly accessed. Vehicles can also get to Highway 392 from WCR 74 by going west 4 miles to Galeton, and then south 3 miles on WCR 51 to the highway. Business Operations The new Galeton-RTF will operate with approximately 20 full time employees during normal hours, Monday -Friday 8am to 6pm, to avoid causing disturbances in the evening, night, and early morning hours. Depending on the work load they may also include Saturday operations periodically. Their work for is expected grow up to (75) seventy-five employees (up to 20 per building) over the next ten years. There will be no public access allowed at the facility, but groups typically no larger than (10) ten visitors ALLES TAYLOR & DUKE, LLC LICENSED PROFESSIONAL ENGINEERS LICENSED PROFESSIONAL LAND SURVEYORS 3610 35TH AVE. UNIT #6 EVANS, CO 80620 970-330-0308 at a time will visit the site periodically. We anticipate that large groups of visitors will carpool by van or bus. The project will generate incremental increases in daily traffic from employees and deliveries as the facility is expanded. Visitors are expected to the facility occasionally, but no public traffic will be allowed. The peak traffic hours for the site are expected to be 1/2 hour before and after the workday. A breakdown of the expected traffic generated by the proposed initial facility construction and full build - out is provided in Table 2 below. Table 2.
