Date Signature: Owner or Authorized Agent Date Print Name Rev 4/2016 Introduction DCP Operating Company, LP (DCP) is in the process of expanding operations in Weld County, Colorado. The expansion project will include adding several compressors and interconnecting pipelines for the purpose of gathering raw natural gas and preparing it for compression and insertion into commercial sales pipelines. This USR application (Use by Special Review) only addresses adding the Crossroads Facility (which includes a compressor station only and not a new gas processing plant) and adding a proposed "up -to -100" foot DCP communications tower. Additional U FI permit applications will be submitted for any future compressor stations, plants, and pipelines. The proposed Crossroads Facility is located east of the intersection of CR 44 and CR 49 south of LaSalle, Co, northeast of Platteville, CO and east of Greeley, CO in central Weld County. • Site address: 24305 CR 44, LaSalle, CO 80645 • Parcel #1053-18-3-00-002 - 130 acres (only 8.7 -acres used for the Crossroads Facility) • Legal Description: SW 1/4, Section 18, Township 4 N, Range 64 W DCP intends to construct the proposed Crossroads Facility during the Summer of 2017 through the Spring of 2018. Since the Crossroads Facility will be an unmanned station once construction is complete, no full-time employees will be working on -site. Two to three times per week, a technician will visit the site to ensure quality control. The Crossroads Facility compressor station will operate 7 days/week, 24 hours/day, and 365 days/year. The access road is proposed to be off of CR 44 southeast of the Crossroads Facility with a double cattle guard installed to minimize any dirt being tracked onto CR 44. Traffic volumes will be minimal after construction since the site will be unmanned. • The Access Permit ##AP17-00165 was approved and issued March 21, 2017. No septic system is required for the Crossroads Facility since the site will be unmanned, Portable toilets, hand washing stations and bottled drinking water will be provided by the contractor during construction (which is expected to last 5-7 months). DCP will provide bottled drinking water and one portable toilet after construction is completed for the DCP technicians that will occasionally visit the site. A water truck will be located on -site during the performance of grading and drainage work to minimize and control dust during construction and will be removed upon construction completion.

Explain, in detail, the proposed amendment to the property. DCP Operating Company, LP (DCP) is proposing to build a new compressor station (Crossroads Facility) near the intersection of CR 44 and CR 49 south of LaSalle, CO and east of Greeley, CO. The proposed equipment is required to expand and enhance the existing natural gas supply currently being collected from nearby gathering systems, and will purify and compress the gas for delivery to pipelines for processing at existing DCP Gas Plants. The gathering system that feeds the Crossroads Facility services producers in the Nob ra ra Shale development. 2. Explain how this proposal is consistent with the intent of the Weld County Code, chapter 22 of the Comprehensive Plan. The proposed use is consistent with the comprehensive plan's intent to foster development of the natural resources of Weld County. Given the limited size of the property (only 8.7 -acres of the 130 -acre DCP parcel will be disturbed), the proposed use should have minimal impact on the surrounding land. a, Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 23 (Zoning) and the zone district in which it is located. The proposed Crossroads Facility is compliant with Chapter 23. The Weld County code provides that oil and gas production facilities are allowed as a matter of right in the agricultural zone district. 4, Describe what type of land uses surround the site. Explain how the proposed use is consistent and compatible with surrounding land uses. The proposed Crossroads Facility is located in an area of the county used primarily as pasture land and already contains various oil and gas operations and facilities. The existing site is surrounded by native pasture land and agricultural fields. By keeping the compressor footprint small (only 87 -acres), DCP intends that surrounding agricultural areas will not be affected by the compressor station's presence. Once the construction is completed, the disturbed area will be replanted with native grasses in compliance with the Weld County seed mix requirements, 5. What are the hours and days of operation? Hours of operation: 24 hours a day, seven days a week, 365 days a year. 6. List the number of full time and/or part time employees proposed to work at this site. The Crossroads Facility will be unmanned after construction is complete; however, one DCP technician will visit the site two -three times a week to ensure quality control. The construction crew required to build the Crossroads Facility will consist of approximately 20-50 people (and construction is expected to last 5-7 months). 7. If shift work is proposed include the number of employees per shift. No shift work is proposed once construction is completed. 8. List the number of people who will use this site. Include contractors, truck drivers, customers, volunteers, etc. During construction of the Crossroads Facility, construction crews will range from 20-50 workers for 5-7 months. During construction, material delivery trucks will make approximately 1-2 trips daily. No additional truck traffic is anticipated after construction is completed. No customers or volunteers will visit the site. 9. If this is a dairy, livestock confinement operation, kennel, etc., list the number and type of animals. There will not be any animals at the proposed Crossroads Facility 10. Describe the type of lot surface and the square footage of each type. Gravel: 8.7 acres of compacted gravel— Crossroads Facility within the fence line Buildings: 9 255 s. f. total (1 -MCC Building, 1 -Compressor Building, 1 -Maintenance Building and 1 -instrument Air Building). 11. How many parking spaces are proposed? How many handicapped (ADA) parking spaces are proposed: Since the Crossroads Facility will be unmanned, there are no proposed parking spaces and no ADA compliant parking spaces being proposed at the site. 12. Explain the existing and proposed landscaping for the site. DCI' intends to install some landscape screening or a screening wall on the east side of the access road to shield the one residence located adjacent to the property to the east and will work with the landowner to accommodate his concerns. Any areas disturbed during construction will be revegetated with the seed mix pursuant to the Weld county seed mix specifications. 13. Describe the type of fence proposed for the site. The Crossroads Facility will have a 6' chain link fence around the entire 8.7 -acre site. 14. Describe the proposed screening for all parking and outdoor storage areas. There will not be any parking or outdoor storage areas located at the Crossroads Facility, therefore no screening is proposed. 15. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. In the unlikely event operations cease at the Crossroads Facility; DCP will remove the equipments communications tower and all of its components in accordance with CO CC regulations. Where possible, materials will be reused or recycled. Where required, materials for disposal will be removed by a licensed contractor and transported to a disposal site. DCP will comply with all COGCC regulations concerning site restoration. 16. Who will provide fire protection to the site? The proposed Crossroads Facility is located within the Platte Valley Fire Protection District, DCP does not use foam and no foam truck is planned to be located at the proposed unmanned Crossroads Facility. The standard guidance from the American Petroleum Institute, and standard guidance followed by most emergency responders, discourages the use of water or foam to extinguish a pressurized gas fire. Furthermore, application of such materials would create an even more dangerous situation by allowing explosive gases to continue leaking out from the source. The only safe way to put out a pressurized gas fire is to stop all new fuel from entering the fire (via emergency shutoff valves to be installed around the compressor station) and to let the fire burn out. Foam and water -based systems are more typically used to suppress fires in oil storage facilities, where it is often important to contain a fire occurring in and around one storage vessel, in order to prevent the fire from spreading to adjacent storage vessels. This facility will have no crude oil storage and limited volumes of any combustible liquids. No foam or water - based suppressants are planned. DCP typically provides more details concerning our fire detection and prevention systems in our building permit submittals for the various buildings that will be built within the Crossroads Facility, and we will do so for this facility, as well. 17. List all proposed on -site and off -site improvements associated with the use (e.g., landscaping, fencing, buildings, drainage, turn lanes, etc.) and a timeline of when you will have each one of the improvements completed. A silt fence will be immediately installed prior to starting any grading work as part of the proposed Crossroads Facility construction (site work will be compliant with the approved grading permit and State Storm water Management Plan Permit). A double cattle guard will be installed at the Crossroads Facility entrance to minimize any dirt being tracked onto CR 44 as soon as construction starts and will remain in place after construction is completed and the site is reseeded per the Weld County required seed mix. A water truck will be on -site during the grading and drainage work being performed to minimize dust and will be removed once the grading and drainage work is completed. Temporary fencing will be installed around the 8.7 -acre site during construction and the permanent 6' tall chain link fence will be installed at the completion of the expansion surrounding the entire Crossroads Facility (5-7 months after construction starts). No off -site improvements are planned as part of the proposed expansion. 18. Describe any new site and equipment lighting. DCP designs lighting to meet the Weld County lighting guidelines and specifically details all site and equipment lighting to point downward at 45 degrees below the horizontal to minimize glare to neighboring properties. See Lighting Plan attached with the USR plans. 19. Prior to Operation: a. A signed copy of the Spill Prevention, Control and Countermeasure Plan shall be provided to the Weld County Environmental Health Services Division of the Weld County Department of Public Health and Environment. b. DCP shall develop an Emergency Action and Safety Plan with the Office of Emergency Management and the Fire District. The plan shall be reviewed on an annual basis by the Facility operator, the Fire District and the Weld County Office of Emergency Management DCP will submit evidence of acceptance to the Weld County Department of Planning Services. ENGINEERING QUESTIONS: 1. Describe how many roundtrips/day are expected for each vehicle type: Passenger Cars/Pickups, Tandem Trucks, Semi-TruckfTrailer/RV (Roundtrip = 1 trip in and 1 trip out of site) Once construction is completed, the Crossroads Facility will be unmanned; however, one DCP technician will visit the site for 60-90 minutes 2-3 times a week in a pickup truck. Estimate 2 roundtrips every other day in a pickup One to two large delivery trucks are also expected to access the Crossroads Facility weekly after construction completion Estimate 2 rounoitrips weekly 2. Describe the expected travel routes for site traffic: Expected travel routes will be traffic coming from Greeley heading East on Highway 34, turning south on CR 49 and turning East on CR 44 and then entering the access road North of CR 44 as approved on the Access Permit #SIP l 7-OO f 65. 3. Describe the travel distribution along the routes: 85% of the vehicle traffic will travel East on Highway 34 then south on CP 49, then travel East on CR 44 into the main entrance. 4. Describe the time of day that you expect the highest traffic volumes from above: 7:00 am — 7:30 am and between 5:00 pm — 5:30 pm daily will be the highest traffic volumes (Monday — Friday during construction). After construction the site will be unmanned, except for a technician visiting the site a few times a week between 7:30 am and 5:00 pm, 5, Describe where the access to the site is planned. The entrance into the Crossroads Facility will be located just east of the existing micro wa ve tower on CR 44. Access Permit #API7-00165 approved 3/2112017. The proposed entrance (with double cattle guards to be installed) will also be used for the existing well head access. 6. Drainage Design: Detention pond summarized in a drainage report compliant with Weld County Code Section 23-12-30 F.1. The Crossroads Facility is within a Non -Urbanizing Drainage Area. ;,1n the historic condition, the Project Site has been delineated into 3 basins and stormwater runoff generated within the basins generally flows from south to north across the Project Site and to the northwestern corner of the USR Parcel, where the runoff is collected via an unnamed drainageway which outfalls onto the adjacent parcel to the north. Flows from the basins combine prior to exiting the USR Parcel. Therefore, for the purposes of determining maximum allowable release rates for the Project Site, the flows from these basins were routed together. In the developed condition, a proposed Water Quality Pond has been included north of and downstream of the Project Site to attenuate the developed runoff, The Water Quality Pond has been sized based on the entire area that is tributary to the pond, which includes the Project Site, portions of the access road, as well as some offsite area. The Modified FAA Method was utilized to size the Water Quality Pond, which has been sized for the developed condition 100 year, 1 hour storm with a 10 yr, 1 hour storm historic (i.e. undeveloped site) release rate, since the Project Site is located in a NON -URBANIZING AREA. WOCV will be provided as part of the required 100 year detention volume. The following table summarizes the pond sizing requirements: Basin Area (ac) Req'd Volume (ac -ft) WQCV Detention via R eq'l Modified Method (ac 100 -if) Volume Year FAA Detention Surface ProV 100 Year d (ac 100 Elevation -ft) Volume Water Year at A - E 0.30 1.86 2.03 11.65 1. The runoff volume stored in the Water Quality Pond will be released at or below historic rates (which are defined as the 10 year, 1 hour storm for an undeveloped site, since the Project Site is located within a NON -URBANIZING AREA) within 72 hours of the storm event via a manually controlled release valve. For each storm e ven t, stormwater collected in the Water Quality Pond will be inspected by a O P Operating Company, LP technician for signs of contamination from leaks/spills. If contamination is not present, the valve will be opened and the pond will be drained after the storm event. The technician will close the valve upon completion of the pond draining. 2. In addition to the manually controlled release valve, an emergency overflow spillway has been provided, which has been sized to safely accommodate the 100 year developed flowrate into the pond with no more than 1.0 ft of depth over the emergency c ve r-flo w crest. 3. The Water Quality Pond will be lined with a pond liner (La clay liner, Bentomat Geoliner or approved equal) to minimize infiltration into the ground. 4. The Water Quality Pond will be located within the fenced area to protect animals and humans from accessing the pond area. 5. The Water Quality Pond includes maintenance access which provides access to the pond bottom and the pond's associated outlet pipe and manual release valve. Since all developed areas of the Project Site (with the exception of a portion of the access road) will be routed through the Water Quality Pond and released via the manually controlled valve within 72 hours of the storm event, offsite releases will be less than or equal to historic 10 year, 1 hour undeveloped site release rate for the Project Site. The water released from the Water Quality Pond will be conveyed overland north/northwesterly to match existing flow patterns of the Project Site and USR Parcel" • See Drainage Report, Colorado Engineer's stamped/signed Certification - Exhibit L ENVIRONMENTAL HEALTH QUESTIONS: 1. What is the drinking water source on the property? During construction, the contractor will provide bottled drinking water for their construction crews. Although the Crossroads Facility will be unmanned after construction completion, DCP will provide bottled water at the site for the DCP technicians that will occasionally visit the site. 2. What type of sewage disposal system is on the property? During construction, the contractor will provide portable toilet facilities and hand washing stations for their construction crews in compliance with the Department of Public Health and Environments portable toilet policy.

DCP proposes to construct a radio communications tower "up to 100 feet" in height at the proposed Crossroads Facility site. DCP designs and constructs such towers at each of its facilities to allow for remote monitoring and control of the facilities. It is imperative that the communications tower be located in the immediate vicinity of the site to allow for the transmission of a reliable signal. A secure location within the site is critical because of the life -safety functions associated with the station's control and emergency shut -down notification features. A list of towers within a 10 -mile radius is attached hereto. There are no existing towers within the 10 -mile radius that DCP would be able to collocate on. Due to safety concerns, DCP does not co -locate its transmitters on third -party towers, Because the transmitters are utilized to remotely control the compression and processing of natural gas and other hazardous materials, DCP requires that only DCP personnel be permitted access to its towers and transmitters to prevent intentional or accidental disruption of communication services, 2. The proposed communications tower will not constitute a hazard to aircraft due to its location. 3. The proposed communications tower will be located within the Property (Parcel No. #1053-18-3- 00-002) and the entire fall zone for the tower will be located within the Property. 4. As noted in Section 1 of this narrative, DCP does not permit co -location on its radio communication towers for safety reasons, 5. The proposed communications tower will be as short as practicable to allow for sufficient signal transmission and will be constructed out of non -reflective materials. 6. Due to its location, as well as the fact that only DCP transmitters will be located on the tower, the proposed tower should not adversely affect human health. 7. The proposed tower will be no taller than the minimum height required for adequate signal transmission between DCP's radio communication towers located in the vicinity. 8, DCP will ensure that the proposed tower complies will all applicable federal and state regulations. 9, The proposed tower will be professionally engineered to ensure the structural integrity of the tower, 10. The proposed tower will be located within the secure fenced boundaries of the proposed Crossroads Facility. 11. Due to DCP's transmission requirements, the proposed tower will be situated in the only feasible location. 12. DCP does riot anticipate any impact on wildlife due to the location of the proposed tower at the proposed Crossroads Facility. 13. DCP submits the following proposed Decommissioning Plan: Decommissioning Plan In the unlikely event operations cease at the Crossroads Facility, DCP will remove the communications tower and all of its components. Where possible, materials will be reused or recycled. Where required, waste materials for disposal will be removed by a licensed contractor and transported to a disposal site. DCP will comply with all COGCC regulations concerning site restoration.

Reponses are included below and are in bold and italicized: Comment 1 Water quality plate details. Response 1 Per our phone coordination with you on May 15, 2017, the proposed Water Quality Pond does not include a traditional multi -stage release structure that includes a water quality plate to release the WQCV over a 40 hour duration. Instead, the Water Quality Pond includes a manually operated release valve which will be opened after a storm event by a trained DCP Operating Company, LP technician once they have inspected the pond to ensure the pond is not contaminated from leaks or spills. The pond will be drained at or below historic release rates (based on NON -URBANIZING AREA release) within a 72 hour period, including draining the required WQCV over a 40 hour duration. As discussed, we have updated the drainage narrative to discuss the WQCV 40 hour release, which has been included in four different locations within the narrative as follows: Item IV. Hydraulic Criteria. B.1 (Page 7) includes the following updated text: "The runoff volume stored in the proposed Water Quality Pond will be released at or below historic discharge rates (which are defined as the 10 year, 1 hour storm, since the Project Site is located within a NON -URBANIZING AREA). At the conclusion of each storm event, stormwater collected in the Water Quality Pond will be inspected by a DCP Operating Company, LP technician for signs of contamination from leaks/spills. If contamination is not present, the technician will open the pond's manually operated release valve and the pond will be drained. The required WQCV will be released over a 40 hour duration following the storm event and the remaining volume (up to the 100 year required detention volume) will be released within 72 hours of the storm event. The technician will close the manually operated release valve upon completion of the pond draining."

The runoff from the Project Site will be detained in a proposed Water Quality Pond and the stormwater within the pond will be inspected by a DCP Operating Company, LP technician for signs of contamination from leaks/spills. If contamination is not present, the manually operated release valve will be opened and the pond will be drained at or below historic release rates (which are defined as the 10 year, 1 hour storm, since the Project Site is located within a NON - URBANIZING AREA) within 72 hours of the storm event. Within the 72 hour draining duration, the WQCV will be released over a 40 hour duration. Item V.B (Page 8) includes the following updated text: "Regarding offsite releases, since all developed areas of the Project Site (with the exception of a portion of the access road) will be routed through the Water Quality Pond and released via the manually operated valve within 72 hours of the storm event (which includes releasing the WQCV over a 40 hour duration), offsite releases will be less than or equal to historic 10 year, 1 hour storm release rates for the Project Site. The water released from the Water Quality Pond will be conveyed overland north/northwesterly to match existing flow patterns of the Project Site and USR Parcel." Item VII.B.1 (Page 12) includes the following updated text: "Runoff generated from the Project Site and small offsite areas is collected and conveyed north/northwesterly via channels and culverts into the proposed Water Quality Pond. Since all developed areas of the Project Site (with the exception of a portion of the access road) will be routed through the Water Quality Pond and released via the manually operated valve within 72 hours of the storm event (which includes releasing the WQCV over a 40 hour duration), offsite releases will be less than or equal to historic 10 year, 1 hour release rates for the Project Site and therefore, downstream improvements should not be adversely impacted by the proposed Crossroads Facility." Comment 2 Depth of flow over the emergency overflow cannot exceed 6" of flow. Response 2 The Water Quality Pond emergency overflow has been revised to be widened from a 10 ft weir crest length to a 41 ft weir crest length to ensure the emergency overflow passes the developed incoming flowrate into the pond at a depth of 6 inches. An update Water Quality Pond Emergency Overflow Weir Calculation and the associated Developed Drainage Map & Drainage Detail sheets have been provided with this letter to replace the original pages.

The owner of the facility, DCP Operating Company, LP, is proposing to construct a Turbine Booster Station which includes various equipment, buildings and access roads. The proposed facility will also include a Water Quality Pond for stormwater attenuation & water quality enhancement. II - GENERAL LOCATION & DESCRIPTION Location A) The USR Parcel is located in the Southwest Quarter & Northwest Quarter of Section 18, Township 4 North, Range 64 West of the 6th Principal Meridian, approximately 9.5 miles southeast of the Town of Greeley, Colorado. The Project Site is located within the portion of the USR Parcel within the Southwest Quarter of Section 18. See Appendix A for a Vicinity Map. B) The site is located in the northeast corner of the intersection of Weld County Road (WCR) 44 & WCR 49. The entrance to the Project Site is proposed to be off of WCR 44, approximately 1,800 feet east of WCR 49. C) No major drainageways exist within the USR Parcel. A small, unnamed drainageway exists in the northwest corner of the USR parcel. This drainageway collects runoff from the majority of the USR Parcel area and directs runoff offsite near the northwest corner of the parcel. As per the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (Map #08123C1775E, Effective January 20, 2016) the project site is located in Zone X— Other Areas, which are areas determined to be outside of the 0.2% annual chance floodplain. Description of Property A) The area associated with the USR Parcel is approximately 131 acres. The developed area is approximately 8.9 acres. For the purposes of this report, "Project Site" refers to the 8.9 acres of developed area associated with the Crossroads Facility. B) The majority of the USR Parcel is undeveloped and consists of cultivated farm field(s). The Project Site is also undeveloped and consists of cultivated farm field(s). As per the National Resources Conservation Service (MRCS), the predominant soils within the study area (portion of USR Parcel located in the SW Quarter of Section 18) are described as follows: 38— Nelson fine sandy loam, 3 to 9 percent slopes Parent material: Residuum weathered from sandstone, slope ranging from 3 to 9%, have a moderately low to high water capacity, are well drained, have a depth to water table greater than 80 inches, are moderately susceptible to erosion from water, and have a high Crestone Project No. 17004 Page I 1 CROSSROADS FACILITY: Final Drainage Report Revised May 16, 2017 susceptibility to wind erosion. The NRCS Hydrologic Soil Group for this type of soil has been classified as Group B (moderate to high infiltration rate; low to moderate runoff potential). 72— Vona loamy sand, 0 to 3 percent slopes Parent material: Alluvium and/or eolian deposits, slope ranging from 0 to 3%, have a high water capacity, are well drained, have a depth to water table greater than 80 inches, are moderately susceptible to erosion from water, and have a high susceptibility to wind erosion. The NRCS Hydrologic Soil Group for this type of soil has been classified as Group A (high infiltration rate; low runoff potential). 73— Vona loamy sand, 3 to 5 percent slopes Parent material: Alluvium and/or eolian deposits, slope ranging from 3 to 5%, have a high water capacity, are well drained, have a depth to water table greater than 80 inches, are moderately susceptible to erosion from water, and have a high susceptibility to wind erosion. The NRCS Hydrologic Soil Group for this type of soil has been classified as Group A (high infiltration rate; low runoff potential). Please refer to Appendix A for NRCS soils data. C) The Project Site does not include a major drainageway and is not located within a regulated floodplain. D) The project involves construction of a Turbine Booster Station which includes various equipment, buildings and access roads. The proposed facility will also include a Water Quality Pond for stormwater attenuation & water quality enhancement. E) The Project Site does not include irrigation facilities. III - DRAINAGE BASINS AND SUB -BASINS Major Basin Description The Project Site is within the South Platte River watershed and does not contain a major drainageway. As per the FEMA Flood Insurance Rate Map the project site is located in Zone X - Other Areas, which are areas determined to be outside of the 0.2% annual chance floodplain. Historic Sub -Basin Description A) The Project Site includes 3 historic sub -basins which are described as follows: Basin H1 (2.56 ac/2% Imp) Basin H1 is located in the west/southwest corner of the Project Site with the existing ground generally sloping from east to west/northwest at slopes ranging from 1.4 to 4.2%. After exiting the Project Site, runoff generated within this basin sheet flows westerly and adjacent to WCR 49, then northerly into the unnamed drainageway which conveys the runoff offsite, near the northwest corner of the USR parcel. Crestone Project No. 17004 Page 12 CROSSROADS FACILITY: Final Drainage Report Revised May 16, 2017 Basin H2 (3.35 ac/2% Imp) Basin H2 is located within the center of the Project Site with the existing ground sloping from south to north/northwest with slopes ranging from 1.5 to 3.0%. After exiting the Project Site, runoff generated within this basin sheet flows north/northwesterly into the unnamed drainageway which conveys the runoff offsite, near the northwest corner of the USR parcel. Basin H3 (2.82 ac/2% Imp) Basin H2 is within the eastern one-third of the Project Site with the existing ground sloping from south to north/northeast with slopes ranging from 2.5 to 4.3%. After exiting the Project Site, runoff generated within this basin sheet flows north/northwesterly into the unnamed drainageway which conveys the runoff offsite, near the northwest corner of the USR parcel. Please Note, the drainage paths for Basins H1 -H3 combine prior to exiting the USR Parcel. Therefore, for the purposes of determining maximum allowable release rates for the Project Site, the flows from these basins were routed together. Please refer to Appendix D for a copy of the Historic Drainage Exhibit. B) Runoff from the Project Site generally sheet flows north/northwesterly into an unnamed drainageway in the northwest corner of the USR Parcel. This drainageway collects the majority of the runoff generated by the USR parcel and conveys the runoff offsite, near the northwest corner of the USR parcel. Developed Basin Descriptions In the developed condition, the Project Site and the access road to the Project Site have been delineated into 7 basins (Basins A -E & OS1-OS2). The developed basins are described as follows: Basin A (1.91 ac/10.4% Imp) Basin A is comprised of a portion of the west half of the proposed access road as well as existing, undeveloped area tributary to the access road. Runoff generated within this basin sheet flows from the proposed access road and open space into a proposed drainage channel on the west side of the access road. The drainage channel conveys the runoff northerly to a proposed culvert at the southeast corner of the Project Site. The proposed culvert conveys the runoff beneath the access road and into Basin B where it is conveyed to the proposed Water Quality Pond via a proposed drainage channel. Basin B (1.26 ac/49.0% Imp) Basin B is comprised of the easterly boundary of the Project Site, more or less. Runoff generated within this basin sheet flows north/northeasterly into a proposed drainage channel which conveys runoff northerly and then westerly into the proposed Water Quality Pond. Basin C (2.02 ac/74.5% Imp) Basin C is located on the easterly portion of the Project Site, west of Basin B. Runoff generated within this basin sheet flows north into a proposed drainage channel which conveys the runoff westerly into the proposed Water Quality Pond. Crestone Project No. 17004 Page 13 CROSSROADS FACILITY: Final Drainage Report Revised May 16, 2017 Basin D (5.14 ac/82.6% Imp) Basin D is comprised of the central portion of the Project Site. Runoff generated within this basin sheet flows north/northwesterly into the proposed Water Quality Pond. Basin E (1.32 ac/79.6% Imp) Basin E is comprised of the westerly portion of the Project Site. Runoff generated within this basin sheet flows northwesterly into a proposed drainage channel which directs flow northerly into the proposed Water Quality Pond. Basin OS1 (2.79 ac/5.5% Imp) Basin OS1 is comprised of a portion of the access road as well as existing undeveloped area south of the access road. The areas located within this basin are not tributary to the Project Site's Water Quality Pond. Runoff generated within this basin sheet flows north/northeasterly to a drainage channel which runs along the southern/western side of the access road which routes the flow to a proposed culvert, which routes the flow northeast under the proposed access road. Basin OS2 (2.70 ac/2.0% Imp) Basin OS2 is located south of the Project Site and west of the proposed access road. Basin OS2 is comprised of existing undeveloped land. Runoff generated within Basin OS2 sheet flows north/northwesterly where it is intercepted by a proposed berm and redirected west around the Project Site. This basin is not tributary to the Project Site's Water Quality Pond. This basin was included to determine berm and channel sizing to route the flow generated by the basin around the Project Site. Please refer to Appendix D for a copy of the Developed Drainage Exhibit. IV - DRAINAGE DESIGN CRITERIA The regulations, guidelines, and drainage design criteria used in the preparation of this report are those contained within the Weld County Engineering and Construction Criteria Manual and the Urban Storm Drainage Criteria Manual — Volumes 1, 2, and 3. Development Criteria Reference and Constraints A) The Project Site is not included in any known previous drainage studies. B) The siting of the proposed facility within the USR parcel was influenced by the location of an existing "40' Wide Permanent Easement for Noble Midstream Partners Pipeline" (located approximately 220' east of the easterly right of way for WCR 49), the location of an existing abandoned well (70' south of the project site, 595' east of the easterly right of way for WCR 49) as well as the locations of numerous gas/oil facilities & pipelines within the USR Parcel and an existing microwave tower which is not within the USR Parcel boundary. The facility was located such that it would not be constrained by the existing gas/oil facility infrastructure. Crestone Project No. 17004 Page 14 CROSSROADS FACILITY: Final Drainage Report Revised May 16, 2017 Hydrological Criteria A) The 1 hour rainfall depths listed below were obtained from the Weld County Engineering and Construction Criteria Manual and were utilized in determining the historic and developed hydrologic calculations, as well as in calculating the required pond volume (Modified FAA Method) for the proposed Water Quality Pond. 2 YR 5 YR 10 YR 100 YR 1.04 1.49 1.76 2.78 The design storms analyzed in this report are as follows: Minor Storm —10 year, 1 hour storm occurrence (utilized for determining the historic release from the Project Site which was used in the Modified FAA Method Water Quality Pond sizing calculation) Please Note — based on coordination with Weld County, the USR Parcel and Project Site are located in a NON -URBANIZING AREA. Major Storm —100 year, 1 hour storm occurrence (open channel, culvert & riprap sizing calculations) B) The Rational Method was used to determine the historic & developed flow rates for the 2, 5, 10 & 100 year storms. The Rational Method formula is described as follows: Rational Formula Q = CIA Q = maximum rate of runoff (cubic feet per second = cfs) C = runoff coefficient I = average intensity of rainfall (inches/hour) for a duration equal to the time of concentration, Tc Where the average intensity ("I") is calculated as follows: = (28.5*P1)/(10+Tc)°78& (Reference 2) I = rainfall Intensity, inches per hour P1 = 1 hour point rainfall depth, inches Tc = time of concentration, minutes A = area (acres) Crestone Project No. 17004 Page 15 CROSSROADS FACILITY: Final Drainage Report Revised May 16, 2017 C) The following table summarizes the historic and developed Rational Method flowrates for the Project Site: Basin Area (ac) Q5 (cfs) Q10 (cfs) Q100 (cfs) Historic H1 2.56 0.1 0.4 3.0 H2 3.35 0.1 1.1 6.1 H3 2.82 0.1 1.2 6.3 Sum H1 -H3 8.73 0.4 2.6 14.6 Developed A 1.91 0.5 1.3 4.9 B 1.26 2.0 2.7 5.8 C 2.02 5.6 6.9 12.3 D 5.14 17.0 20.6 35.1 E 1.32 4.2 5.1 8.7 Sum A -E 11.65 19.5 24.6 45.8 OS1 2.79 0.4 1.5 6.6 O52 2.70 0.1 1.1 5.7 D) Urban Drainage & Flood Control District (UDFCD) equations were utilized to determine required Water Quality Capture Volume (WQCV) for the Project Site. E) A diversion berm/swale(s) is proposed along the south side of the Project Site to keep offsite runoff from entering the Project Site. The diversion berm/swale(s) will direct the offsite runoff to the west, where it will combine with other historic flows which will not be attenuated in the proposed Water Quality Pond. Refer to Appendix B for Hydrologic Calculations and Reference Materials. Hydraulic Criteria A) Autodesk Hydraflow Express Extensions was used to determine channel sizes necessary to convey the applicable developed design flow. Hydraflow employs the Manning's Equation in open channel calculations, which, for the purposes of design, the flow is assumed to be steady and uniform (allowing the use of Manning's Equations). The Manning's Equation can be stated as follows: Manning's Equation Q = 1.49 ARz/3 Sf1/z n = Manning's roughness coefficient A = flow area (ft2) Crestone Project No. 17004 Page 16 CROSSROADS FACILITY: Final Drainage Report Revised May 16, 2017 R = hydraulic radius Sf = friction slope (i.e. slope of the pipe, ft/ft) The design parameters for the channels are as follows: Maximum Velocity = 5.0 feet per second (grass lined) Maximum Velocity = 16.0 feet per second (riprap lined) Manning's roughness coefficient (n) = 0.045 B) The proposed Water Quality Pond has been sized based on the entire area that is tributary to the pond, which includes the Project Site, portions of the access road as well as offsite areas. The Modified FAA Method was utilized to size the Water Quality Pond, which has been sized for the 100 year, 1 hour storm with a 10 yr, 1 hour storm (NON -URBANIZING AREA) historic release rate. WQCV will be provided as part of the required 100 year detention volume. The following table summarizes the Water Quality Pond sizing: Basin Area (ac) Req'd WQCV Volume (ac -ft) Req'd 100 Year Detention Volume via Modified FAA Method (ac -ft) A - E 11.65 0.30 1.86 1. The runoff volume stored in the proposed Water Quality Pond will be released at or below historic discharge rates (which are defined as the 10 year, 1 hour storm, since the Project Site is located within a NON -URBANIZING AREA). At the conclusion of each storm event, stormwater collected in the Water Quality Pond will be inspected by a DCP Operating Company, LP technician for signs of contamination from leaks/spills. If contamination is not present, the technician will open the pond's manually operated release valve and the pond will be drained. The required WQCV will be released over a 40 hour duration following the storm event and the remaining volume (up to the 100 year required detention volume) will be released within 72 hours of the storm event. The technician will close the manually operated release valve upon completion of the pond draining. 2. In addition to the manually operated release valve, an emergency overflow spillway has been provided, which has been sized to safely accommodate the 100 year developed flowrate into the pond. 3. The Water Quality Pond will be lined with a pond liner (i.e. Bentomat Geoliner or approved equal) to minimize infiltration into the ground. 4. The Water Quality Pond will also be located within the fenced area to protect animals and humans from accessing the pond area. Crestone Project No. 17004 Page 17 CROSSROADS FACILITY: Final Drainage Report Revised May 16, 2017 A summary of the Water Quality Pond includes: Pond Invert: 4832.50 Top of Pond Embankment: 4838.00 Provided 100 Year Pond Volume at 100 Yr WS Elev: 2.15 ac -ft (required volume = 1.86 ac -ft) 100 Yr WS Elev.: 4836.50 Emergency Overflow Crest Elev: 4836.50 Provided Freeboard: 1.5 ft C) Permanent erosion control features consist of the proposed Water Quality Pond, riprap erosion protection throughout the various onsite channels and where concentrated flows will enter and exit the proposed Water Quality Pond. The pond's emergency overflow will include a concrete cut-off wall as well as buried riprap to help protect the pond berm in the event of a pond overflow. Refer to Appendix C for all Hydraulic Calculations (which include channel sizing, culvert sizing, riprap sizing and Water Quality Pond sizing) and Reference Materials. V - DRAINAGE FACILITY DESIGN General Concept A) The storm drainage conveyance and storage elements have been designed to safely collect and convey runoff generated by a 100 year storm event within the Project Site. The runoff from the Project Site will be detained in a proposed Water Quality Pond and the stormwater within the pond will be inspected by a DCP Operating Company, LP technician for signs of contamination from leaks/spills. If contamination is not present, the manually operated release valve will be opened and the pond will be drained at or below historic release rates (which are defined as the 10 year, 1 hour storm, since the Project Site is located within a NON -URBANIZING AREA) within 72 hours of the storm event. Within the 72 hour draining duration, the WQCV will be released over a 40 hour duration. B) Regarding offsite releases, since all developed areas of the Project Site (with the exception of a portion of the access road) will be routed through the Water Quality Pond and released via the manually operated valve within 72 hours of the storm event (which includes releasing the WQCV over a 40 hour duration), offsite releases will be less than or equal to historic 10 year, 1 hour storm release rates for the Project Site. The water released from the Water Quality Pond will be conveyed overland north/northwesterly to match existing flow patterns of the Project Site and USR Parcel. Crestone Project No. 17004 Page 18 CROSSROADS FACILITY: Final Drainage Report Revised May 16, 2017 C) Multiple tables, figures and drawings have been included within the appendices of this report and include the following: APPENDIX A— General Information Vicinity Map NRCS Soils Data APPENDIX B— Hydrologic Calculations (Historic & Developed Condition) Rational Method Calculations Hydrologic Calculation Reference Materials APPENDIX C — Hydraulic Calculations (Historic & Developed Condition) Channel Sizing Calculations Culvert Sizing Calculations Riprap Sizing Calculations Water Quality Pond Sizing Calculations Hydraulic Calculation Reference Materials APPENDIXD— Maps Historic Drainage Exhibit Developed Drainage Exhibit Drainage Details D) In addition to the Water Quality Pond and its associated features, hydraulic structures associated with the proposed Crossroads Facility are limited to drainage channels, swales and culverts. Channels (CH) have a bottom width of 5 feet, 4:1 side slopes and a minimum depth of 1 ft. Proposed channels are located within Basins A, B, C, E, OS1 and O52. Swales have a `V' section with 3:1 side slopes and a minimum depth of 0.5'. A swale is proposed south of Basin D to direct flow away from the proposed building & parking lot located at the south side of Basins C & D. Culverts are proposed in two locations along the access road. An 18" culvert (STM1) is proposed in Basin A to convey stormwater flows generated within Basin A beneath the access road and into Basin B. An 18" culvert (STM2) is proposed within Basin OS1 to convey stormwater flows generated within Basin OS1 beneath the access road. The Water Quality Pond release is discussed in previous sections. Specific Details A) The proposed Water Quality Pond includes a maintenance access on the south side of the pond which provides access to the bottom of the pond. Additionally, the pond's release pipe which the manually controlled valve is located on, includes a headwall/cut-off wall and concrete apron on the upstream end (within the pond) and a cut-off wall on the discharge end. The pond's emergency overflow will include a cut-off wall as well as buried riprap to help protect the berm in the event of a pond overflow. Crestone Project No. 17004 Page 19 CROSSROADS FACILITY: Final Drainage Report Revised May 16, 2017 B) Maintenance Plan All stormwater facilities designed herein are privately owned & maintained. The property owner will be responsible for regular maintenance and repairs of the drainage facilities which include drainage channels, culverts and the Water Quality Pond and its associated features. Drainage channels, culverts and pond shall be inspected routinely on at least a quarterly basis and after significant storm events. Routine maintenance activities for the channels, culverts and pond (including pond manual release valve/outfall, emergency overflow and maintenance access) include mowing/weed control, trash & debris removal, erosion mitigation through replanting/watering, overgrown vegetation removal and structural repair. The following table provides routine maintenance guidelines: Summary of Routine Maintenance Activities Maintenance Activity Minimum Frequency Look for: Maintenance Action Trash/Debris Removal Monthly Trash & debris in channel and pond Remove and dispose of trash and debris Mowing Twice annually for native species Excessive grass height/aesthetics Mow native grass to a height of 6" Inflow Point/Trash Rack/ Outlet Works Cleaning As needed; after significant storm events; w/ other maintenance Clogged inflow points, channel culverts, pond release; ponding water Remove and dispose of debris/trash/sediment to allow proper function Weed Control As needed, based upon inspections Noxious weeds; Unwanted vegetation Treat w/ herbicide or hand pull; Consult the local weed inspector Vegetation Removal/ Tree Thinning As needed, based upon inspections Trees and plant vegetation around channel features/ bottom, inflow points, pond release, emergency overflow Remove vegetation with tree trimming tools; Consult with arborist concerning evasive species; restore grade and surface Rodent Damage As needed, based upon inspections Holes, small piles of dirt, raised burrows Evaluate damage; consult animal control specialist or DOW for guidance Mosquito Treatment As needed Standing water/mosquito habitat Treat w/ EPA approved chemicals Based on the routine inspections, provide periodic minor and major maintenance activities for the channels, culverts and pond (including pond manual release valve/outfall, emergency overflow and maintenance access) include sediment removal from the channels, riprap pads, pond bottom, pond release; erosion repair; overgrown vegetation removal; structural repair/replacement.

The Water Quality Pond proposed with this report has been sized in accordance Weld County detention requirements. B) Drainage Concept 1. Runoff generated from the Project Site and small offsite areas is collected and conveyed north/northwesterly via channels and culverts into the proposed Water Quality Pond. Since all developed areas of the Project Site (with the exception of a portion of the access road) will be routed through the Water Quality Pond and released via the manually operated valve within 72 hours of the storm event (which includes releasing the WQCV over a 40 hour duration), offsite releases will be less than or equal to historic 10 year, 1 hour release rates for the Project Site and therefore, downstream improvements should not be adversely impacted by the proposed Crossroads Facility. 2. The Project Site is not included within a Master Drainage Plan and therefore, not impacted by previous plan requirements/recommendations. 3. The Project Site is not encumbered by irrigation facilities. 4. Please refer to Appendices A through D for specific technical criteria and references. VIII - REFERENCES 1.
