Name: Christopher fIumbe Title: Executive Vice President, General Counsel /kz,z__, [Signature Page to Officer's Certificate] Ell ZEN MIDSTREAM Ren Compressor Station Planning Questionnaire Answer the following questions per Section 23-2-260. A, B, C & E 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. Explain the proposed use and business name. Zen Midstream LLC (Zen) proposes to build and operate a new gas compressor station in the SWNW and NWSW of Section 33, Township 7N, Range 62W. The gas compressor station would be approximately 7.38 acres with access to the facility from County Road 74, utilizing existing Access Permit APOG20-00060. 2. Explain the need for the proposed use. The Ren Compressor Station will facilitate the compression and transport of natural gas produced at nearby oil and gas production facilities. The natural gas gathering pipelines in this area operate at a line pressure above the pressure of the production facilities. The high pipeline pressure prevents the gas produced at the production facilities from entering the pipeline and being transported offsite. Natural gas production from the surrounding production facilities will be routed to the Ren Compressor Station where the gas will be compressed so it can be transported offsite via the existing pipeline infrastructure. 3. Describe the current and previous use of the land. The proposed property is private property in rural unincorporated Weld County. The current land use of the property is agricultural for grazing livestock activities. 4. Describe the proximity of the proposed use to residences. The nearest Residential Building Unit is approximately 4,300 feet southeast of the proposed Ren Compressor Station. 5. Describe the surrounding land uses of the site and how the proposed use is compatible with them. The Ren Compressor Station is located in an area mapped as rangeland and zoned agricultural. There are multiple other existing and planned oil and gas facilities in the area surrounding the Ren Compressor Station that it would serve. Additionally, there are natural gas pipeline easements within and adjacent to the parcel. 6. Describe the hours and days of operation (i.e. Monday thru Friday 8:00 a.m. to 5:00 p.m.). The proposed Ren Compressor Station will continuously operate twenty-four hours a day, seven days a week. Truck traffic to the site is anticipated to mainly occur between the hours of 7:00 am to 5:00 pm. 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. ItiPEI ZEN MIDSTREAM The location will be unmanned and the primary method of product delivery to the site will be by pipeline, however, the location was designed with the capability for materials to be loaded and off-loaded via tanker trucks. No full-time or part-time personnel will be specifically stationed at this compressor station, but the site will be visited daily by both full-time personnel and contractors for inspection and monitoring. Employees and contractors will visit the site on an 'as needed' basis for loading and off-loading operations. The Ren Compressor Station will also be visited by full-time personnel and contractors at regularly scheduled intervals for routine maintenance. 8. Describe the maximum number of users, patrons, members, buyers or other visitors that the site will accommodate at any one time. Once operational, a maximum of 2-8 employees/contractors can be expected to use this site at a time. This site will not be open to the public. 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.). There will be no animals allowed on the site at any time. 10. List the types and number of operating and processing equipment. The proposed processing equipment for the compressor station facility will include: • three (3) skid -mounted compressors, • two (2) blowdown tanks/vessels, • two (2) produced water tanks, • five (5) scrubbers, • one (1) discharge coalescer filter, • one (1) gas/glycol exchanger, • one (1) regen skid, • one (1) BTEX skid, • one (1) glycol make-up tank, • instrument air equipment, • one (1) dry air receiver, • two (2) generators, • two (2) VRUs, • three (3) blowdown blowers, • one (1) oxygen destructor, • one (1) air compressor, • one (1) air receiver vessel, • one (1) condensate treater, • one (1) slug catcher, • pig receivers, and • other minor support equipment. 11.

A barbed-wire fence will be installed around the perimeter of the location and stormwater and drainage features will also be installed. 12. Describe the size of any stockpile, storage or waste areas. The Ren Compressor Station will contain storage areas for liquids collected from the pipeline and storage of materials needed for the operation and maintenance of processing equipment onsite. The proposed storage items are listed below. The topsoil will be stripped from the disturbance area before construction and a 1.0 -acre stockpile will be on the east side of the disturbance area. The topsoil stockpile will be reseeded to prevent erosion and noxious weeds and will be used to reclaim the site when the compressor station is decommissioned. Proposed storage at the Ren Compressor Site includes: • 2 x 500 bbl produced water tanks each with lined secondary containment • 6 x 500 gallon lube oil tanks each with 750 gallon containment • 3 x 500 gallon coolant tanks each with 750 gallon containment • 3 x 100 gallon eco waste tanks with 150 gallon containment • 6 x 330 gallon methanol tanks each with 370 gallon containment • 1 x 1,000 gallon glycol tank with 1,500 gallon containment 13. Describe the method and time schedule of removal or disposal of debris, junk and other wastes associated with the proposed use. Waste generated at this location will be disposed of at an approved commercial waste facility. During construction, a dumpster will be provided for debris, junk, and other wastes associated with construction activities, and waste will be removed from the site monthly or more frequently if necessary. During operation, a dumpster may remain onsite for debris, junk, and other general rubbish and will be scheduled for monthly removal, or more frequently as needed. Other waste streams generated onsite will be removed as needed. Refer to the Waste Management Plan included in this application. 14. Include a timetable showing the periods of time required for the construction of the operation. The anticipated start of construction of the Project is Q4 2024 and will conclude in Q4 2025. 15. 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 surface type at the proposed site is undisturbed rangeland. Existing Parcel (rangeland) = 27,878,400 sq ft (640 acres) P roposed Pad = 321,473 sq ft (7.3 acres) • Graded pad (gravel) = 277,913 sq ft (6.3 acres) • Topsoil Stockpile (dirt - reseeded) = 43,560 sq ft (1.0 acres) Buildings = 8,160 sq ft • Compressor Building = 7,500 sq ft • PDC = 660 sq ft P roposed Access Road (gravel) = 87,300 sq ft (2.0 acres) Ea ZEN MIDSTREAM • Existing (gravel) = 78,240 (1.8 acres) • New (gravel) = 9,060 sq ft (0.2 acres) 16. How many parking spaces are proposed? How many handicap -accessible parking spaces are proposed? There are no planned formal parking spaces at the facility. 17. Describe the existing and proposed fencing and screening for the site including all parking and outdoor storage areas. Once constructed, the Ren Compressor Station will have a barbed-wire fence designed to be consistent with existing fences on the property. The fence will be installed around the perimeter of the site with a cattle guard at the access to the facility. 18. Describe the existing and proposed landscaping for the site. The existing landscaping at the site is rangeland/herbaceous. Once construction is completed, the areas not needed for long-term operation of the compressor station will be re -seeded with an NRCS-approved native seed mix. 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. Zen would decommission the facility, remove all equipment, and return the site to its pre. construction condition. Refer to Decommissioning Plan included with this application. 20. Describe the proposed fire protection measures. The Ren Compressor Station will employ a range of fire protection measures to mitigate risks and ensure operational safety. This includes the installation of automation with the capability to promptly detect potential fires and remotely shut down the facility if needed. Fire extinguishers will be strategically placed on -site during critical phases of operations to provide immediate fire response capabilities. Moreover, fire-resistant construction materials are utilized to minimize potential fire outbreaks. The implementation of regulator maintenance with general housekeeping further enhances the effectiveness of the fire protection measures. Zen Midstream personnel and contractors visit the site daily and will provide the first line of defense for preventing fire outbreaks and quickly responding to emergencies. The Ren Compressor Station is within the Briggsdale Fire Protection District and potential fire -related impacts are projected to be within the capacity of the local fire district. 21. Explain how this proposal is consistent with the Weld County Comprehensive Plan per Chapter 22 of the Weld County Code. The proposed Ren Compressor Station is consistent with the Weld County Comprehensive Plan Sec. 22-2-60. - Natural resource goals and objectives, which states: "Support responsible energy and mineral development." Zen has developed the Project, and this facility, to conserve the land and minimize the impact on surrounding land and the existing surrounding land uses by locating the compressor station near other existing oil and gas facilities and infrastructure, as well as minimized the footprint of the facility as much as possible. tr?el ZEN MIDSTREAM 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 III of Chapter 23 of the Weld County Code.) The current zoning for the proposed Ren Compressor Station is zoned Agriculture. 23. Explain how this proposal will be compatible with future development of the surrounding area or adopted master plans of affected municipalities. The Ren Compressor Station is located in an area considered non -crop rangeland. This rangeland is mainly used for periodic grazing of livestock. The surrounding area is primarily composed of similar non -crop rangeland with other oil and gas facilities in the vicinity. A key reason this location was selected for a compressor station was based on the centrality of the site in relation to oil and gas facilities that already exist, and future sites that are approved for development within the surrounding area. This compressor station will occupy a relatively small amount of the surrounding rangeland and the periodic grazing of livestock will continue on the parcel where this compressor station is located. The Ren Compressor Station is located approximately seven (7) miles south of Briggsdale and is not anticipated to impact the development plans for nearby municipalities. 24. Explain how this proposal impacts the protection of the health, safety and welfare of the inhabitants of the neighborhood and the County. Zen Midstream chose this facility location that was located next to or near areas that had previously been developed for natural gas handling purposes and that have limited potential for environmental effects; these facility locations are sited at some distance from sensitive areas (residential areas, schools, hospitals, etc.). The proposed facility is located in rural/agricultural areas and is approximately 7 miles from the nearest population center (which include small rural towns or larger cities). The Ren Compressor Station is not located in close proximity to schools or larger residential areas, and the nearest residence is approximately 4,300 feet from the the site. There are several mitigation measures that have been identified by Zen that will be implemented for potential air emissions and noise impacts to protect nearby populations as well as the greater populations in the Project area. Some of these mitigation measures include: Construction Mitigation Measures • Minimizing exhaust emissions from diesel and gasoline -fueled construction equipment and vehicle engines. • Minimizing vehicle and equipment idling time to the extent practical during construction. • Utilize dust suppression techniques to minimize fugitive dust during construction. • Limiting emissions from potential surface coating by purchasing and installing most piping and structural components that have been prepared and coated in shops prior to shipment to the construction site. • Zen will not burn any brush, trash, or materials generated from construction activities. Operational Mitigation Measures • Zen will install equipment that, at a minimum, meet state and/or federal emission limitation regulations. Pla ZEN MIDSTREAM • Engines will be equipped with Non -Selective Catalytic Reduction (NSCR) systems to reduce CO, VOC, and formaldehyde emissions below appliable emission standards and permit limits. • Zen will develop and implement an operation and maintenance plan consistent with the manufacturer's recommendations for good combustion practices. • Zen will operate and maintain compressors according to manufacturer recommendations. • Zen will conduct optical gas imagining camera surveys monthly to catch and repair fugitive leaks from piping components at compressor stations. • Zen will install non -emitting process controllers and will conduct routine maintenance to prevent malfunctions from occurring. • Zen will have enclosures (buildings) around the proposed new compressor skids to reduce noise from the facilities. • Zen conducted a Noise Impact Assessment (NIA) to assess operational noise levels against the maximum permissible dBA noise levels stated in CRS 25-12. Operations will comply with the maximum permissible noise levels (MPNLs) of the codes as summarized in the NIA. With these proposed mitigation measures in place, the proposed Project would not subject nearby communities or populations to disproportionate adverse impacts. 25. Describe any irrigation features. If the proposed use is to be located in the A (Agricultural) Zone District, explain your efforts to conserve prime agricultural land in the locational decision for the proposed use. The proposed Ren Compressor Station is located in an A (Agricultural) Zone District, but the current use of the property is rangeland for livestock grazing, no agricultural activities are occurring on the property and the construction and operation of it will not impact any irrigation features. 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 proposed Ren Compressor Station is not located within any Overlay Zoning District or a Special Flood Hazard Area. 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. Stationary Source Air Permits are required, and requirements of those applications have been submitted and are pending review/approval by CDPHE. Additionally, Zen will obtain a Construction Stormwater Permit from the CDPHE for the construction of the Ren Compressor Station.

ZEN MIDSTREAM Ren Compressor Station Process Description The Ren Compressor Station is a field gas gathering and compression station in Weld County, CO. This new facility serves well pads in the area via gas gathering pipelines. Gas leaving the station is sent to the nearby high-pressure sales pipeline via a custody transfer meter and also to the well pads via return gas lift pipelines. Water and condensate leave the station via water and oil pipelines via custody transfer meters. GAS • Gas entering the station is compressed through three natural gas engine -driven compressors. The gas is then dried to sales pipeline requirements via a glycol dehydration unit • Fuel gas for engines and other gas users in the station is made from high pressure station discharge gas that is post -dehydration. • Entrained liquids and compressor drip liquids are collected under pressure and routed to a condensate treating vessel where it is separated into condensate and water. Vapors leaving the treater are routed through the vapor recovery compressor and returned to the gas inlet to the station. • Total gas leaving the pad is metered via an orifice flow meter prior to leaving via a third -party gas sales line. BLOWDOWNS AND DEHY • Vapors from compressor and equipment blowdowns as well as the dehy BTEX unit are collected via a vapor recovery blower and routed to the vapor recovery compressor and returned to the gas inlet to the station. CONDENSATE • Condensate is routed to two pressurized condensate storage vessels. Vapors collected from the pressurized storage vessels are routed to the vapor recovery compressor and returned to the gas inlet to the station. • Condensate leaves the site via LACT with a coriolis flow meter via a third -party oil sales line. In cases oil sales line downtime, condensate may be trucked from location. • The loading of pressurized condensate trucks will not result in any vapors being emitted. PRODUCED WATER • Water is routed to two 500 bbl produced water tanks. • Produced water leaves the site via produced water transfer pump with a magnetic or Coriolis flow meter and goes to a third -party water gathering pipeline. In cases of water line downtime, produced water may be trucked from location. POWER AND AIR • Initially generator power will be utilized. Once electrical grid power is available, it will be used on site to power the control system, the oil LACT, produced water pump, VRUs, blowers, heat trace and lighting. • Starting air is utilized to start the compressor engines. Instrument air is utilized to operate the station control valves. ZEN MIDSTREAM, LLC REN COMPRESSOR STATION PROCESS FLOW DIAGRAM REVISION C DATE 30 -Apr -24 BY CONDER 60°F ih:,.

By following this communication plan, Bison will ensure that property owners remain informed, engaged, and supported during emergency situations, fostering a sense of security and trust in the response capabilities. ZEN MIDSTREAM Ren Compressor Station Decommissioning Plan When the proposed Ren Compressor Station reaches the end of its operational life, the components will be dismantled and removed from the site. Zen Midstream's lease with the property owner, Jerry W. Cass, requires us to decommission and restore the site at our expense. The decommissioning plan would commence at the end of the lease term or in the event of twelve (12) months of non -operation. At the time of decommissioning, the proposed facility components will be dismantled and removed using minimal -impact construction equipment. All underground infrastructure that is not removed will be abandoned in place by industry standards, or standards set forth by Weld County. All materials will be safely recycled or disposed of at an approved disposal facility. Zen Midstream will be responsible for all decommissioning costs. Upon termination of the proposed facility, all equipment will be removed. The ground will be regraded to match the surrounding contour of the land. Revegetation of the site will be considered complete when the percent plant cover reaches at least 80% of pre -disturbance vegetative cover and is free of noxious weeds. The pre -disturbance vegetation cover shall be determined by the undisturbed surrounding areas. Zen Midstream would also be willing to evaluate coordinating reclamation efforts with Weld County Extension, Public Works, and the Soil Conservation District. In addition to the required analysis of specific conditions to be addressed during the decommissioning process, particular focus will be placed on landowner coordination, including advance contact as necessary by rule or plan providing discussions regarding the process and addressing any concerns there may be.

Its approximate geographical coordinates are 40°31'50.41" N and 104°20'05.99" W. The red boundary delineates the compressor station In Figure 1. The surrounding area is primarily characterized by residential and agricultural land use. The orange line denotes the proposed approach road, which will be designed by others and is not within the scope of this report. The total area of the site measures 7.41 acres. Figure 1: Vicinity Mop Ren Compressor Station The current site conditions are agricultural with no significant geological features. The total impervious area is minimal, consisting primarily of agricultural fields and dirt/gravel roads surrounding the site. According to the NRCS website, the majority of the site falls under Hydrologic Soil Group B. The specific soil type is Olney fine sandy loam. The soil report from NRCS can be found in Appendix A. Floodplain Analysis The floodplain was delineated by the Federal Emergency Management Agency (FEMA) for this project. FEMA has designated this area as a Zone D meaning there has not been a study of the area. The site location is indicated by a red pin on the map below. 2424-00365 Ren Compressor Station 0 250 500 1,000 1300 2,000 Figure 2: FENIA Floodplain Map of Site Design Hydrologic Analysis The site will be covered in gravel, and the ground's impermeability will be increased to 40% according to the Mile High Flood District.

Using the NOAA Atlas 14, the 1 -hour 5 -year and 100 -year storm events were found to be 1.18 inches and 2.59 inches, respectively. The site's historical conditions indicate undisturbed grasslands with an imperviousness of 5%, as per the MHFD. Hydraulic Analysis The site currently lacks stormwater conveyance or storage facilities. It is an undeveloped grassland area that generally drains from west to east. Runoff will be directed offsite using detention ponds with corresponding outlets. Detention Ponds The required size of the detention ponds was determined using the modified FAA method for a 5- and 100 -year storm. The required volume to be contained and corresponding pond volume are shown below. Calculations for the sizing of both detention ponds and corresponding outlets can be found in Appendix D. Table 2: Basin Summary Basin ID Pond (acre Volume -ft) y 5- ear Required (acre Volume -ft) 100 Volume Required acre -year -ft ) Outflow (cfs) 1 0.322 0.103 0.271 3.70 2 0.507 0.129 0.147 3.14 Ponds release rates are controlled by a standpipe in each pond. Each standpipe has holes drilled in the side to control the release rate to drain the pond in 40 hours per MHFD and Weld County criteria. Details for the standpipes are located on the drainage maps in Appendix E. Maintenance Maintenance of the detention pond after the first year of installation requires monitoring vegetation growth and removing invasive species as necessary. Monthly to quarterly, orifices should be inspected, and debris removed. Due to the gravel and soil surfaces of the site, an inspection of sediment deposition should be conducted every 1-3 years. The impacts of site constraints are minimal due to the isolation of the site from nearby streets and structures. The proposed road design is on the opposite end of the site and uphill from the detention pond and spillway, reducing the impacts of overflow from the pond on the surrounding features of the site. Variance Requests There are no variance requests. Conclusion The drainage design suitably contains stormwater runoff from the site's surface through the installation of swales around the perimeter and two ponds on the northeast and southeast corners. Analysis of the swales shows that the swales are sized to convey the major storm event. The detention ponds are also sized to contain the full volume of estimated runoff from all three basins within the required 40 hour drain time and are designed with a spillway incase of emergency flows into the ponds. 2424-00365 Ren Compressor Station APPENDIX A- SOIL MAPS 2424-00365 Ren Compressor Station 4 Meters 0 150 300 600 900 Feet 0 500 1000 2000 3000 Map projection: Web Mercator Corner coordinates: WGS84 Edge tics: UTM Zone 13N WGS84 Soil Map —Weld County, Colorado, Northern Part MAP LEGEND Area of Interest (AO!)

Introduction This document provides site -specific information for the Ren Compressor Station located in Weld County, Colorado. The information in this document relates specifically to the time during the construction and operation of the proposed compressor station. The Ren Compressor Station will utilize an existing access point (Access Permit APOG20-00060) off of County Road 74. The Ren Compressor Station will be in the SWNW and NWSW of Section 33, Township 7N, Range 62W, and is located on parcel 0715-33-0-00-002 owned by Jerry W Cass. The parcel is zoned Agricultural within Weld County's Ag-Rural planning area and is currently used for rangeland activities. An Application for a Use By Special Review (USR) is being prepared for the Weld County Planning Department Construction of the proposed Location, with associated cut and fill slopes, would initially disturb approximately 7.3 acres. The proposed compressor station facility equipment will include three (3) skid -mounted compressors enclosed in buildings installed on a graded pad. Onsite chemical storage will include the following: • 2 x 500 bbl produced water tanks each with lined secondary containment • 6 x 500 gallon lube oil tanks each with 750 gallon containment • 3 x 500 gallon coolant tanks each with 750 gallon containment • 3 x 100 gallon eco waste tanks with 150 gallon containment • 6 x 330 gallon methanol tanks each with 370 gallon containment • 1 x 1,000 gallon glycol tank with 1,500 gallon containment There will be 4 -strand barbed wire fencing around the facility. Stormwater and drainage features will also be installed. Pending approval from Weld County the anticipated start of construction of the Project is Q4 2024 and conclude in Q4 2025. Article II. Dust Mitigation Plan Specific Data Soils Ren Compressor Station Soil type(s): 44 — Olney fine sandy loam, 0 to 6 percent slopes The total area of soil disturbance including access, in acres, is approximately 9.3 acres (7.3 acres facility disturbance + 2.0 acres access road). The Haul Route is 4.5 miles along County Road 74, coming from Hwy 392 to the west, which is a maintained county road as depicted on the Haul Route Map. Truck Traffic Vehicle traffic associated with the Ren Compressor Station will range from passenger cars and pickups to semi - truck vehicles. The duration of construction activity at this site is estimated to last approximately 12 months. Construction is anticipated to commence at Ren Compressor Station in Q4 2024. 4,14 ZEN MIDSTREAM During the operation phase, the expected number of per day roundtrips is estimated to be 10 passenger cars/pickups, and 2 annual semitruck trips during the life of operation for this location. Article III. Best Management Practices Zen will employ the following practices for control of fugitive dust caused by their operations: • Zen will minimize the amount of fugitive dust through the use of speed restrictions. All vehicles will be subject to a speed limit of 15 MPH on all lease roads to minimize dust. • Zen uses traffic signs when leaving the location to remind drivers of specific routes to utilize. • Automation of the facility which provides the ability to monitor the site and complete basic tasks remotely reduces the need for physical trips to the site. • Restriction of construction activity during high -wind days. • Zen will stabilize the topsoil stockpiles utilizing vehicle tracking perpendicular to slope angle for short term stabilization and drill seed/crimped straw mulch application for longer term stabilization measures to suppress fugitive dust caused solely by wind. • Zen will work diligently to ensure all disturbed surfaces are properly stabilized to minimize any dust migration. • Zen will primarily utilize water and/or commercial dust suppressants to limit the creation and spread of fugitive dust on access road and facility locations. While Zen plans to use freshwater for dust suppression efforts, in some situations, chemical -based palliatives may be considered as a necessary long-term dust mitigation solution. Should chemical soil binding compounds such as magnesium chloride or similar products be used, Zen will maintain the requisite safety data sheets (SDS) and make said SDS documentation available to state and local government officials. • Zen will use only fresh water (potable or non -potable) to conduct dust suppression activities within 300 feet of the ordinary high-water mark of any water body. Operators will not use any of the following fluids for dust suppression: • Produced water • E&P Waste or hazardous waste • Crude oil or any oil not specifically designed for road maintenance. • Solvents • Any process fluids Article IV. Cumulative Dust Impacts Where circumstances dictate, Zen will work to minimize cumulative dust impacts resulting from site operations. Such situations may include nearby Oil and Gas truck traffic, sharing of unpaved roads, as well as other major sources of dust in the area which may or may not be derived from Oil and Gas activities. As necessary, Zen will work with offset operators and any other dust source activities within a reasonable proximity to actively manage cumulative dust impacts. Article V.

WELD COUNTY, CO ZEN MIDSTREAM Ren Compressor Station Lighting Narrative Lighting Plan following the standards set forth in Section 23-2-250.D, if applicable. Lighting at the Ren Compressor Station will comply with the following lighting standards: 1. Sources of light shall be shielded so that light rays will not shine directly onto adjacent properties where such would cause a nuisance or interference with the use on the adjacent properties. 2. Neither direct nor reflected light from any light source will create a traffic hazard to operators of motor vehicles on public or private streets/roads. No colored lights will be used that may be confused with or construed as traffic control devices. Zen Midstream has included a layout of the location of the down -shielded lights at the Ren Compressor Station on the following page.

EXECUTIVE SUMMARY Urban Solution Group, LLC (Urban) was commissioned to prepare a Noise Impact Assessment (NIA) report for the proposed Ren Compressor Station (Ren location), to be located near Briggsdale, Colorado, and operated by Zen Midstream, LLC (Zen Midstream). The purpose of this report is to assess predicted environmental noise impacts from the proposed operations on the surrounding environment. The results of this assessment will compare the predicted levels of the Ren Compressor Station operations to the maximum permissible noise level (MPNL) limits described in the Colorado Revised Statutes (CRS) 25-12 noise regulation. The results of the NIA indicate the predicted unmitigated sound levels for the proposed compressor station operations are below the A -weighted permissible noise levels for an industrial zone as required by the CRS 25-12 noise regulation. As such, no noise mitigation is required at this time. Below is a summary of the noise model results.

REGULATIONS AND NOISE STANDARDS SUMMARY Noise for compressor stations located in Weld County, Colorado, are regulated through the Colorado Revised Statute (CRS) Title 25 Article 12 noise regulation. This regulation sets the MPNLs, which limit noise emitted from facilities within the study area over a specified period, as measured at noise compliance points. These allowable limits are dependent on the land use zoning within the study area. An overview of the CRS regulation is presented below. CRS 2542 Noise Regulation — Brief Overview CRS 25-12 states that operations must comply with the maximum permissible noise levels (MPNLs) in Table 1 below unless otherwise required by CRS 25-12. 1) Every activity to which this article is applicable shall be conducted in a manner so that any noise produced is not objectionable due to intermittence, beat frequency, or shrillness. Sound levels of noise radiating from a property line at a distance of twenty-five feet or more therefrom in excess of the db(A) established for the following time periods and zones shall constitute prima facie evidence that such noise is a public nuisance: Table 1. Maximum Permissible Noise Levels (CRS 25-12-103) Daytim = (7:00 Nighttime p.m. - 7:00 a.m.) (7:00 a.m. - 7:00 p.m.) Residential 55 dB(A) 50 dB(A) Commercial 60 dB(A) 55 dB(A) Light industrial 70 dB(A) 65 dB(A) Industrial 80 dB(A) 75 dB(A) 2) In the hours between 7:00 a.m. and the next 7:00 p.m., the noise levels permitted in subsection (1) of this section may be increased by ten db(A) for a period of not to exceed fifteen minutes in any one -hour period. 3) Periodic, impulsive, or shrill noises shall be considered a public nuisance when such noises are at a sound level of five db(A) less than those listed in subsection (1) of this section.

NOISE IMPACT ASSESSMENT The NIA was conducted for the proposed Ren Compressor Station using a three-dimensional computer noise modeling software. This is a predictive model to aid in ascertaining the e nvironmental impact of the proposed facility during normal facility operations on the surrounding e nvironment. The results of this assessment will compare the predicted levels of the Ren Compressor Station operations to the permissible noise level limits described in CRS 25-12 noise regulation. A brief explanation of the methodology is presented first, followed by noise model results for the compressor station. Methodology All computer models and predicted noise levels generated for the assessment are developed with the commercial noise modeling software SoundPLAN 9.0. The ISO 9613-1 and 2 international standards are utilized in this software as they are widely accepted both internationally as well as in North America. The algorithms used in the commercial software package are based on methods and theory accepted in the environmental acoustics community. Both detailed equipment technical information and location -specific topography, are used to generate comprehensive n oise predictions that take into account environmental conditions, buildings, ground cover and barriers (natural, topographical, and otherwise). Note that actual field measurements may differ from modeled noise levels on any given day due to ever changing environmental factors and other n oise sources in the study area not explicitly in the computer model. Table 3 below lists the conditions used in the model. Table 3. Conditions Used in SoundPLAN 9.0 Software Parameter Modeled Input and Description Temperature 55°F — Represents typical summer evening temperature Topography Modeled as is, with proposed location modified per grading plan Wind Velocity 2.2 - 11.2 receiver mph — ISO 9613 uses a slight downwind condition from each noise source to each Wind Direction From the noise source to the receptor points Relative Humidity 40% - Typical summer evening relative humidity Absorption Ground Ranges from 0.0 for water bodies & major roadways up to 1.0 for thick grasslands It is assumed that facility operating conditions do not change significantly between the daytime and nighttime periods. The resulting predicted noise levels are compared to the MPNLs outlined in the regulation to determine if the subject facility is compliant.

There are two important properties that describe sound; frequency and amplitude. Frequency is determined by the rate of movement and is measured in cycles per second, which is known as Hertz (Hz). A healthy human ear can hear 20 Hz — 20,000 Hz (Figure A). The sensation associated with frequency is commonly referred to as the pitch of a sound. High frequencies produce a higher pitch and vice versa. The amplitude of a sound is determined by the maximum displacement of air molecules produced by the vibrations. These displacements lead to pressure fluctuations in air, which are expressed in decibels (dB). Decibels are a logarithmic ratio of sound pressure over the standard threshold of hearing. The more energy a sound has, the larger the pressure fluctuations, resulting in a louder sound. Figure A: Auditory Field Displaying Thresholds for a Human Ear at Different Frequencies [Bruel and Kjaer] Limit of Damage Risk Frequency weightings are applied to measurements to provide a better match between measured results and human perception. Each weighting, in relation to their frequency components, allows for a consistent measurement of the different type of noise sources. A - weighted decibel sound pressure levels (dBA) are measurements recorded from a sound level meter measuring sounds similar to the response of the ear (Figure B). While C -weighted (dBC) measurements are for low -frequency components. 7\1\k-erirban Solution Group, LLC 14230 Elati St. Suite 200, Denver, CO I Phone (720) 749-2916 15 oal'URBAN SOLUTION c;ROUP Figure B: Common Sound Weightings Up to 20 kHz, Z -Weighting Means No Weighting [Bruel and Kjaer] Each measurement has an exponential time factor. Slow time weighting is the most common for environmental noise measurements and will be used for these measurements. For recording over long periods of time, the sound level meter records each weighted decibel reading with an equivalent, or average, continuous sound level reading (Leq). Leq represents the same energy as the actual time varying sound signal (Figure C). LAeq refers to the equivalent continuous sound level for an A -weighted measurement. Figure C: Sound Level Recording Displaying Leq, a Steady -State Sound Level, Over a Noise Measurement [Bruel and Kjaer] Environmental noise is a combination of various noise sources. These sources may include; vehicle traffic, aircraft flyovers, wind, weather disturbances, commercial or industrial activities, and other short-term events. These sources create "background noise". Background noise varies throughout the day, generally following the cycle of human activity.

Ambient noise includes sound from other industrial noise not subject to this directive, transportation sources, animals and nature. Average Sound Level See Energy Equivalent Sound Level. A -weighted sound level The sound level as measured on a sound level meter using a setting that emphasizes the middle frequency components similar to the frequency response of the human ear. Calibration A procedure used for the adjustment of a sound level meter using a reference source of a known sound pressure level and frequency. Calibration must take place before and after the sound level measurements. C -weighted Sound Level The C -weighting approximates the sensitivity of human hearing at the industrial noise levels (above 85 dBA). The C -weighted sound level is more sensitive to the sounds used to assess the low- frequencies than the A -weighted sound level. It is sometimes used to assess the low - frequency content of complex sound environments. Day Night Sound Level (Ldn) Is the average noise level over a 24 -hour period. The noise between the hours of 22:00 and 07:00 is artificially increased by 10 dB. The nighttime noise is weighted to consider the decrease in community background noise. Daytime Average Sound Level The time -averaged A -weighted sound level measured between the daytime hours, usually defined as 7:00 am to 7:00 pm. Decibel (dB) A unit of measure of sound pressure that compresses a large range of numbers into a more meaningful scale. The basic unit of measurement for sound levels. dBA The decibel (dB) sound pressure level filtered through the A filtering network to approximate human hearing response. See dB and A -weighted Sound Level. dBC The decibel (dB) sound pressure level filtered through the C filtering network. See dB and C - weighted Sound Level. 7\1\k-erirban Solution Group, LLC 14230 Elati St. Suite 200, Denver, CO I Phone (720) 749-2916 URBAN SOLUTION GROUP Energy Equivalent Sound Level (Leq) The Leq is a single -number average, sound level that represents cumulative acoustical energy as measured over a specified time interval. Facility Any operation used in exploration, processing, development and transportation of energy resources. Frequency The number of oscillations per second for a sound wave. Impulse Noise Unwanted, instantaneous sharp sounds that create sudden impulses of pressure similar to gunfire and explosions. Noise Reduction The difference in sound pressure level between two points Nighttime Average Sound Level (Lnight) The time -averaged A -weighted sound level measured between the nighttime hours, usually defined as 7:00 pm to 7:00 am. Ldn See Day night sound level. Leq See Energy Equivalent Sound Level. Noise Generally understood as unwanted sound. Noise Impact Assessment (NIA) Identifies the expected sound level emanating from operations and receptor points are placed in locations related to compliance. It also identifies what the permissible sound level is and how it was calculated. Noise Reduction Coefficient (NRC) A single number rating of the sound absorption properties for a material. An NRC value of zero indicates the material is purely reflective. An NRC value of one indicates perfect absorption. 7\1\k-erirban Solution Group, LLC 14230 Elati St. Suite 200, Denver, CO I Phone (720) 749-2916 19 URBAN SOLUTION GROUP Octave Band An octave band is a frequency band that spans one octave. A band is said to be an octave in width when the upper band frequency is twice the lower band frequency. Octave bands are commonly used in engineering acoustics. The nine common octave bands used for the study of industrial noise are identified by their center frequencies as 31.5Hz, 63Hz, 125Hz, 250 Hz, 500 Hz, 1000 Hz, 2000 Hz, 4000 Hz, and 8000 H z . Point Source A source that radiates sound from a single point. Generally used to model equipment when looking at the sound impact over a large area. Receiver A person or piece of equipment that is affected by noise. Sound A series of vibrations transmitted through the air, or other medium, and can be heard when they are processed by the human ear. Sound Level Meter (SLM) An instrument that contains a microphone and filter used to measure sound levels, using standard frequency -weightings and exponentially weighted time averaging. Sound Power Level A physical measurement of the amount of power a sound source radiates into the surrounding air. It is the rate at which sound energy is emitted, or received, per unit time. Sound Pressure Level (SPL) The sound level received at a given location. The decibel equivalent of the rate of sound pressure waves at a measured location, usually with a microphone. Sound Transmission Class (STC) An integer rating that measures how well a barrier or building partition attenuates sound. Indicates how well a barrier is at stopping sound from transmitting through it. 1/3 Octave Band The 1/3 octave band analysis provides a finer breakdown of sound energy distribution (compared to full octave band) as a function of frequency. 7\1\t/cerirban Solution Group, LLC 14230 Elati St. Suite 200, Denver, CO I Phone (720) 749-2916 20 ZEN MIDSTREAM Ren Compressor Station Traffic Narrative 1.

The information in this document relates specifically to the time during the construction and operation of the proposed compressor station facility. The Ren Compressor Station will utilize an existing access point (Access Permit APOG20-00060) off of County Road 74. The Ren Compressor Station will be in the SWNW and NWSW of Section 33, Township 7N, Range 62W, and is located on parcel 0715-33-0-00-002 owned by Jerry W Cass. The Ren Compressor Station is zoned Agricultural within Weld County's Ag-Rural planning area and is currently used for rangeland activities. An Application for a Use By Special Review (USR) is being prepared for the Weld County Planning Department. Construction of the proposed Location, with associated cut and fill slopes, would initially disturb approximately 7.3 acres. The proposed compressor station facility equipment will include three (3) skid - mounted compressors, enclosed in buildings installed on a graded pad. Onsite chemical storage will include the following: • 2 x 500 bbl produced water tanks each with lined secondary containment • 6 x 500 gallon lube oil tanks each with 750 gallon containment • 3 x 500 gallon coolant tanks each with 750 gallon containment • 3 x 100 gallon eco waste tanks with 150 gallon containment • 6 x 330 gallon methanol tanks each with 370 gallon containment • 1 x 1,000 gallon glycol tank with 1,500 gallon containment There will be barbed-wire fence installed around the facility. Stormwater and drainage features will also be installed. Pending approval from Weld County the anticipated start of construction of the Project is Q4 2024 and conclude in Q4 2025. 2.0 Waste Compliance This plan is being developed and consistent with the requirements of local government (Weld County) recommendations. Zen will utilize these general guidelines at the onset of construction activities as well as perform the necessary management and maintenance throughout the project life. Waste management should be included in the planning process for all projects and activities. Zen personnel are responsible for the proper identification, handling, and storage of waste, both at the facility and throughout the shipment process. Waste can only be disposed of at approved disposal or recycling facilities. Contractors and third parties may not bring any waste materials generated outside field boundaries into Zen facilities for disposal, recycling, or beneficial reuse without prior written approval. A dumpster may be provided onsite for miscellaneous trash and debris generated onsite. Waste generated on location will be disposed of at a permitted commercial waste facility (see list of current disposal facilities below).

This includes oily gloves, rags, absorbent pads, rod packing, and spent bags filters. These items are used in the maintenance of E&P exempt oil and produced water process equipment. Zen may install centralized disposal locations in the operations area for disposal of this waste. The covered waste containers are emptied on an as needed basis. The oily trash is transported to a permitted disposal facility under waste manifest to ensure chain of custody control. Tank Bottoms Liquid wastes consisting of Sand/Bacteria/Water, resulting from cleaning a produced water tank are transferred via hydro -vac truck to a permitted water recycling/disposal facility via vacuum truck or transport tanker truck. Solid wastes at the bottom of oil production tanks and produced water tanks including, but not limited to, sand, sludge, and other solids are transported to a permitted disposal facility via transport truck. Tank bottoms will be allowed to accumulate in the tank or vessel until operation requirements necessitate removal. Tank bottoms will be sent off site after receipt of 2 all ZEN MIDSTREAM laboratory analysis that indicates TENORM is not present. The waste will be sent to a disposal facility that is licensed to accept E&P wastes that can contain hydrocarbons or possible benzene contamination. Liquid and solid waste is transported to permitted recycling/disposal facilities under waste manifest to ensure chain of custody control. 4.0 Record keeping system Licensed third -party transporters will provide load tickets with the following information: o The date of the transport o The identity of the waste generator o The identity of the waste transporter o The location of the waste pickup site o The type and volume of waste o The name and location of the treatment or disposal site. For waste that requires a manifest, a manifest specific to the disposal site will be filled out after the waste is loaded. A Zen representative will sign the manifest and take a copy before the waste leaves location. The manifest will be brought to the disposal site and signed by a disposal site representative and transporter. 5.0 Spill Response and Remediation Occasionally, spills of productions fluids may occur during operations that result in localized impacts to soils on or near the facility. All reportable spills are immediately investigated by Zen personnel and/or Clean Harbors Environmental. Impacted soils are assessed to determine if they exceed regulatory cleanup standards and require removal, treatment, or disposal. Characterizing potentially contaminated soils is accomplished by field -screening the impacted soils to determine relative hydrocarbon concentrations, and/or by collecting samples of the impacted soils and sending the samples to an approved commercial lab for analysis per applicable Table 915- 1 constituents. All contaminated soils exceeding regulatory cleanup standards are excavated and managed/disposed of appropriately. If a spill incident is subject to agency reporting requirements, the appropriate agencies are notified within the regulatory timelines. Impacted soils that exceed applicable cleanup standards are typically excavated and taken to an off -site commercial disposal facility that is authorized to accept that type of waste. 6.0 Facility Decommissioning Facility closure will be pursuant to Rule 911.a at the time of decommissioning, unless the Director determines that a substantive change to the site requires a Form 27, or a reportable Spill or an historic impact is discovered during facility operation or removal. 7.0 Contingency Plan The contingency plan for contaminated soil will be to remediate and dispose of according to ECMC 900 Series rules. All contaminated soils exceeding regulatory clean-up standards are excavated and managed/disposed by immediate transfer to an off -site commercial disposal facility that is authorized to accept that type of waste. If any incident is subject to agency reporting requirements, the appropriate agencies are notified within the regulatory timelines. 3 1.1 ZEN MIDSTREAM 8.0 Best Management Practices Standard • Inspections: Conduct inspections and preventative maintenance on flow lines and storage tanks; use proper containers, keep lids on containers, and store containers properly to prevent overflow or spillage; maintain secondary containment for recovery of spills; and review SPCC Plans if applicable. • Sampling/Disposal/Inspections: Prior to transporting of the waste, Zen will ensure that a waste profile is on file with the disposal company or will characterize the waste for profiling. When the waste is sent for disposal, the waste will be identified on the waste shipping manifest. Any associated sampling data, inspection results, and/or SDS information will be kept with the waste profile documentation. Unforeseen wastes not listed in the Waste Stream table will be stored and disposed of in accordance with all regulations applicable to the specific waste. • Zen will not bury or burn trash or other waste materials at the facility location. • Secondary containment berms shall be constructed of steel rings or walls with a synthetic or engineered liner. • All liner seams will be welded and tested in accordance with applicable ASTM international standards. • Trash receptacles will be designed, maintained, and operated to exclude wildlife, and to protect public safety, the environment, and wildlife from exposure to overflowing, leak prone, or insecure trash receptacles. 4 COMPRESSOR STATION SURFACE AGREEMENT This Agreement Station Surface Compressor ent") is entered into and effective this Iseday of p May, 2024 (the "Effective Date"), by Jerry W.
