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 proposed Prairie Compressor Station and adding a proposed "up -to -100 -`ft." DCP communications tower. Additional USR permit applications will be submitted for any future compressor stations, plants, and pipelines. The proposed Prairie Compressor Station is located south of CR 50 and east of CR 59, south of Kersey, Co in central Weld County,. • Parcel #1053-01-0-00-023 and Parcel #1053-01-3-00-039 • Legal description: a portion of W 1,4 of Section -1 , Township 4 North, Range 64 West • The proposed Prairie Compressor Station will only utilize approximately 10 -acres for the permanent location of the facility and approximately 2.5 -acres for the temporary contractor laydown yard and temporary construction trailers out of the 144.1 USR boundary parcel. Pending Weld County BOCC approval, DCP intends to construct the proposed Prairie Compressor Station staring in January 2019 Since the proposed Prairie Compressor Station will be an unmanned station once construction is complete, no full-time employees will be working on -site. Typically, one DCP technician will visit the site daily for a few hours to ensure quality control. The proposed Prairie Compressor Station will operate 7 days/week, 24 hoursidaye and 365 days/year. The existing access road to the proposed Prairie Compressor Station is east of CR 59 and then south into the compressor station with a 60' turning radius and a cattle guard to be installed to minimize any dirt being tracked onto CR 59. Traffic volumes will be minimal after construction since the site will be u nmanned. Existing Access Permit #AP I B-00231 approved March 21, 2018. No septic system is required for the proposed Prairie Compressor Station since the site will be u nmanned. Portable toilets, hand washing stations and bottled drinking water will be provided by the contractor during construction (which is expected to last 8-12 months). DCP will provide bottled drinking water and one portable toilet after construction is completed for the DCP technician that will occasionally ✓ isit the site. An Air Permit was filed in May 2018 with the State of Colorado Air Pollution Control Division that includes all the proposed natural gas processing equipment to be installed at the proposed Prairie Compressor Station. The Air Permit is expected to be approved and released by the end of 2018. Permit #18WE0506. A State of Colorado Department of Public Health & Environment Construction Stormwater Permit was filed on September 12, 2018 — permit is expected to be approved and released by October 1, 2018. Exhibit D Use by Special Review (UDR) Questionnaire PLANNING UESTIONS: 1. Explain, in detail, the proposed use of the property. DCP Operating Company, LP (DCP) is proposing to build a new compressor station (Prairie) south of CR 50 and east of CR 59, south of Kersey, CO. The proposed natural gas processing 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 proposed Prairie Compressor station services producers in the Niobrara 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 proposed Prairie Compressor Station (only approximately 10 -acres will be permanently disturbed for the proposed compressor station out of the 144.1 -acre USR boundary property), the proposed use should have minimal impact on the surrounding land. 3. 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 Prairie Compressor station 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 Prairie Compressor station is located in an area of the County used primarily as agricultural and pasture land and already contains various oil and gas operations and facilities. The existing site is surrounded by irrigated crop land, agricultural fields and a few residents. By keeping the proposed compressor footprint small (approximately 10 -acres out of the 144.1 -acre USR property boundary), DCP intends that surrounding agricultural areas will not be affected by the compressor station's presence. Once the construction is completed, the approximately 25 -acre contractor laydown yard/parking area that was disturbed will be reseeded with a seed mix compliant with the Weld County Public Works specifications. 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 proposed Prairie Compressor station will be unmanned after construction is complete; however, one DCP technician will visit the site daily to ensure quality control. 7. If shift work is proposed include the number of employees per shift. No shift work is proposed. 8. List the number of people who will use this site. Include contractors, truck drivers, customers, volunteers, etc. During construction of the proposed Prairie Compressor Station, construction crews will range from 20-50 workers. During construction, one-two medium delivery trucks (10,000 lbs. - 26,000 lbs)will access the site weekly. After construction, there will be two transport trucks (26)000 lbs. 4-) accessing the site twice a week 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. Non -applicable. 10. Describe the type of lot surface and the square footage of each type.

How many parking spaces are proposed? How many handicapped (ADA) parking spaces are proposed: Since the proposed Praline Compressor Station 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. DCP intends to install a 16' tall pre -cast concrete wall around the entire Prairie Compressor Station with some additional berms located on the west side of the wail to provide some additional screening. DCP is working with the neighbors regarding their concerns. Any areas disturbed during construction will be revegetatod with a seed mix compliant with the Weld County Public Works seed mix specifications. 13. Describe the type of fence proposed for the site. The proposed Prairie Compressor station will have a 6' chain link fence with barbed wire and tan slats around the water quality pond and launcher/receiver meter areas that are not included within the proposed 16' tail precast concrete wall. (See C-6 screening plan) 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 proposed Prairie Compressor Station, however, a WWI precast concrete et wall will surround the entire proposed facility. 15. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. In the unlikely event operations cease at the Prairie Compressor Station, DCP will remove the equipment, communications tower and all of its components in accordance with COGCC 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 Prairie Compressor Station is located within the Platte Valley Fire Protection District. 17. List ail 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 startling any grading work as part of the proposed Prairie Compressor Station Facility construction (site work will be compliant with the approved grading permit and State of Colorado Stormwater Permit). A double cattle guard will be installed at the main entrance to the proposed Prairie Compressor station to minimize any dirt being tracked as soon as construction starts and will remain in place after construction is completed. The contractor laydown yard/parking area w/// be revegetated with a seed mix compliant with the Weld County Public Works seed mix specifications. 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 site during construction and the permanent 16' tall precast concrete wall will be installed at the completion of the compressor station construction that will surround the entire Prairie Compressor Station (7-9 months after construction starts). No off -site improvements are planned as part of the proposed project. 18. Describe any new site and equipment lighting. DCP designs lighting to meet the We/d County lighting guidelines and specifically details all site and equipment lighting to be LED lights and point downward at 45 degrees below the horizontal to minimize glare to neighboring properties.

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-Truck/Trailer/RV (Roundtrip = I trip in and I trip out of site) Once construction is completed, the Prairie Compressor Station will be unmanned; however, one DCP technician will visit the site daily in a pickup truck to ensure quality control: Estimate I roundtrip every day in a pickup truck One to two large transport trucks are also expected to access the Prairie Compressor Station weekly after construction completion Estimate 2 roundtrips weekly 2. Describe the expected travel routes for site traffic: Expected travel route will be traffic coming from Greeley heading east on Highway 34, turning south on CR 49 and turning east on CR 50 and then south on CR 59 entering the existing access road (Access Permit #API 8-00231). Alternatively traveling from Greeley heading east on Highway 34 turning south on CR 59 and turning east onto the main access road. 3. Describe the travel distribution along the routes: 50% of the vehicle traffic will travel from Greeley east on Highway 34 then south on CR 49, then travel east on CR 50 then south on CR 59 into the main existing access road. 50% of the vehicle traffic will travel east from Greeley on Highway 34 turning south on CR 59 and turning east onto the main access road. 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 (Monday — Friday during construction). 5:30 pm daily will be the highest traffic volumes After construction the site will be unmanned, except for a technician visiting the site daily for a few hours between 7:30 am and 5-00 pm. , Describe where the access to the site is planned. The existing access road to the proposed Prairie Compressor station is located on the east side of CR 59 - Permit #AP18-00231, The proposed main Prairie entrance (double cattle guard to be installed 100' back from the road and entrance to have a 60' turning radius) is shown on the attached plat maps. 6. Drainage Design: Detention pond summarized in a drainage report compliant with Weld County Code Section 23-12-30 F11. The proposed Prairie Compressor station is within a Non -Urbanizing Drainage Area. Currently, stormwater runs along eastewest cultivated furrows and then to the northeast to Box Elder creek, stormwater runoff from the proposed Prairie Compressor station will flow into Box Elder Creek, then off -site via the Creek to the northeast, and eventually into the South Platte River about 5 miles northeast of the site. In the proposed site development, the site will be graded generally flat, with a slight ridge running east -west along the center of the new compressor station. Water will flow on the surface both north and south away from this ridge so that runoff and winter snowmelt do not collect around the main process area, and those swales will drain to the new WQF pond (water quality feature) to be installed at the northeast edge of the site. swales will be located around the periphery of the facility in such a way as to convey runoff from all process areas associated with the compressor station into the WQF pond. 100 of the storm runoff from the process area will be collected in a new WQF/pond. pond. The design of the new W E/pond will be based on collecting 100% of a 100-yr/I-hr~' duration storm. After the rain from a large storm subsides, a DCP technician will check for any signs of accidental contamination from leaks/spills. If any contamination is found, the contaminated water will be removed by DCP and hauled to a refinery for recycling. Non -contaminated water will be released via a normally closed manual valve to flow off -site in a controlled manner. The rate of water discharge is limited so as to not exceed the historical stormwater flow from the site, calculated from a 10-yrr/I hr storm based on the pre -development runoff factor of imperviousness. Water will not be held for longer than 72 hours after capture from a rainstorm. Drainage off -site will continue to be routed to Box Elder Creek. The DCP technician will close the valve upon completion of the pond draining. In addition to the manually controlled release valve, an emergency overflow spillway will be provided, which has been sized to safely accommodate the 100 -year developed flowrate into the pond with no more than 1r g ft of depth over the emergency overflow crest. The Water Quality Pond will be lined with a pond liner (Le. clay liner, Bentomat Geoliner or approved equal) to minimize any infiltration into the ground. The Water Quality Pond will be located within the fenced area to protect animals and humans from accessing the pond area. There is a 100-yr floodplain mapped on the western edge of the property, extending 300 to 500 feet on both sides of Box Elder Creek The proposed Prairie Compressor Station will be built entirely out of the floodplain. No process equipment will be installed within the 100-yr floodplain. See Drainage Report - Exhlbit_M 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 proposed Prairie Compressor Station will be unmanned after construction completion, DCP will provide bottled water at the site for the DC! ' technician that will visit the site daily to ensure quality control. 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 Environment's portable toilet policy, Although the proposed Prairie Compressor Station will be unmanned after construction completion, DCP will have one portable toilet to be used by the DCP technician that will visit the site daily to ensure quality control. 3. If storage or warehousing is proposed, what type of items will be stored: Condensate Methanol Labe oil Coolant The -Ethylene Glycol (TEG) Produced water Used engine oil Used filters 4. Describe where and how storage and/or stockpile of wastes, chemicals, and/or petroleum will occur on this site. Wastes will not be stockpiled on site.

DCP proposes to construct a radio communications tower "up to 100 feet" in height at the proposed Prairie Compressor Station 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. If a third party user requested to collocate on this proposed tower, they would have to comply with DCP's safety, security and structural installation requirements. 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. #105301000023) and the entire fall zone for the tower will be located within the Property. 4. DCP will only authorize third -party users to co -locate on the DCP tower if the third party complies with DCP's safety, security, engineering and structural installation requirements, 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, 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, state and county regulations. 9.

As part of the installation of the proposed Prairie Compressor Station, DCP has developed a sound mitigation plan, as described below, that will ensure sound standard compliance through a combination of utilizing newest technology equipment/fans, and engineering measures. With available new technology for various equipment, DCP will comply with the applicable noise standard for the equipment to be installed at the proposed Prairie Compressor Station. • some of the natural gas processing equipment will be installed in fully enclosed and insulated buildings to minimize sound emissions, Exhibit Q Community Participation Plan DCP is committed to developing and sustaining a Community Participation Plan that facilitates effective stakeholder communications and public information regarding the installation of the proposed Prairie Compressor Station. The following describe the objectives and activities that comprise Objectives DCP has identified three objectives integral to an effective community participation plan: I. Build and Maintain Relationships. DCP has identified a list of key stakeholder contacts to ensure inclusion and proactive outreach, and to provide a pathway for questions and concerns. • An introductory letter was mailed to 34 households/residents within a -mile radius on July 18th, 2018 in an effort to solicit comment and input from our neighbors regarding the proposed Prairie Compressor Station. • DCP then followed up and held a neighborhood meeting on Tuesday, July 31st, 2018 to discuss the proposed installation of the proposed Prairie Compressor Station and discuss their concerns. 16 neighbors attended. 2. Educate Stakeholders. Through regular outreach, DCP is currently striving to educate stakeholders about operating procedures, emergency preparedness, community benefits, and industry awareness. 3. Provide openness DCP will identify various avenues through which the local community can access relevant information, and can provide comments and feedback. DCP understands that trust is founded upon strong, open and accessible relationships. Communication Activities. The following activities will help DCP meet its objectives as stated above: to build relationships, educate stakeholders and provide openness about the proposed Prairie Compressor Station activities and issues. This three-part approach addresses our local community's need for information regarding our plans and updates related to the construction of the proposed Prairie Compressor Station. Neighbor Response Line: DCP is working to establish a toll free number for all of Weld County that will allow citizens and neighbors to communicate directly with the correct DCP employees depending on the nature of their requests. While the toll free number is being established, the Prairie neighbors can use the email and phone number listed below with any questions, DCP olorado DCPMidstream.com. 970-378-8364 Emergency calls will continue to be directed to 911. CommunityTown I-il�a l ls; DCP is currently identifying a schedule of town hall meetings, extending through the construction period throughout 2019, Town halls will be held occasionally and local stakeholder input will be sought into the effectiveness of the format. The first town hall meeting with the neighbors was held on July 31st, 2018. • 16 neighbors attended out of 34 households notified of the meeting. Topics of discussion included: project overview, growth of natural gas within Weld d county, safety, environmental stewardship, reliable operations, proposed construction timeline, emergency preparedness, responding to questions and concerns about proposed compressor operations, sound and light mitigation measures being implemented, and social opportunities to build and maintain relationships. Electronic/Mobile Access: DCP is implementing a social media collaboration tool which allows interested neighbors to subscribe for updates and to provide feedback. This approach provides the additional benefit of mobile access to ensure openness and responsiveness. Postings may include topics such as operational planned updates, construction routes, unplanned activities, schedule reminders and input regarding town hall meetings, and questions and answers. DCP is currently getting this collaboration tool set up, but during the interim, DCP can be contacted at: P clora.da P P idstream,com 970-378-6364 Exhibit R Decommissioning Plan In the unlikely event operations cease at the Prairie Compressor Station, DCP will remove the natural gas processing equipment, buildings, tanks, meters, communications tower and all of its components in accordance with COGCC 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. Exhibit S Wetland/Rare Species Assessment DCP hired a wetland biologist with Oi a on & Associates to prepare the attached wetlandirare specifies assessment completed May 25, 2018 confirming the current floodplain and wetland boundary adjacent to the proposed Prairie Compressor Station. No portion of the proposed Prairie Compressor Station will be built within the 100 -year floodplain as indicated on the site plan and equipment layout drawings (see Plat Maps — Exhibit E), i See Wetland/Rare Species Assessment dated May 25. 2018 attached OLSSON ASSOCIATES May 25, 2018 hristina White White Engineering Inc. 3620 W. loth Street, Suite #410 Greeley, CO 80634 Re: Wetland Delineation and Stream Assessment le DCP Crosstie Project Weld County, Colorado Olsson Project # 018-1532 Dear Mrs. White: Olsson. Associates (Olsson), on behalf of White Engineering a wetland completed delineation and stream assessment for the DCP Crosstie Project (Project) located in Weld County, Colorado, southeast of Weld County Roads (WCR) 59 and 50. Olsson completed a .desktop review of the Project area, which included a .review of United States Geological ica � I Survey (U) Topographic Maps, United States Fish and Wildlife Service (USFWS) Wetland mapper data, Natural Resources rces onservation Service (NRCS) Soil Survey data, aerial photography, and Federal Emergency Management Agency (FEMA)flood lain maps. Olsson performed the wetland delineation and stream assessment on May 14 and 23, 2018 using the methodology described in the U.S. Army Corps of Engineers(USACE) 1987 Wetlands Delineation Manual and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Great Plains Region (Version 2.0). Background Data Review According to the USGS 7.5 -minute topographic map and the site visit, the topography within the Project area is sloped northeast (Figure 1). The USFWS Wetland mapper data suggests that the Project area contains one wetland, Box Elder Creek. Box Elder Creek connects to the South Platte River, and is therefore considered Waters of the United States (WOUS). The NRCS Soil Survey depicted two mapped soil types in the Project p � area —Colombo clay loam, 0 to 1 percent slopes and Nunn clay loam, 0 to 1 percent slopes (Figure 2). Nunn clay loam, 0 to 1 percent slopes is the soil type associated with the e wetland on site. This well -drained soil is often found on terraces and is not listed on the National Hydric Soils list for La rimer County. Aerial photography shows the Project area containing cropland around Box Elder Creek (Figure 2). The FEMA flood lainshows p map the northern and northwestern portions of the Project area are within a Zone A floodplain (Figure ). 1525 Raleigh Street, Suite 400 TEL 303 237,2072 Denver, CO 80204 FAX 3O3 237.2659 wwvv.olssonassociates.com OLSSON ASSOCIATES Field Investigation Olsson conducted the field investigation by walking the Project area, looking for wetlands and waterways, and inspecting potential wetland areas for hydrophytic vegetation, hydric soils, and wetland hydrology. Olsson performed a visual inspection of the entire Project area for any potential wetland areas or waterways not previously identified. Olsson observed one stream in the Project area. Olsson mapped the ordinary high water mark (HM) and obtained data points on the perimeter of the stream along the northern portion of the parcel to determine whether fringe wetlands were present adjacent to the stream (Figure 4). The ordinary high water mark was determined based on water levels, watermarks, and change in vegetation. The wetland -upland, boundary was determined based on a decreased presence of hydrophytic vegetation, increased presence of upland vegetation, a lack of hydric soil characteristics, and lack of hydrological cues. Olsson also conducted threatened and endangered species habitat and raptor nest surveys by observing the Project area for potential suitable habitat. Investigation Results The Project area contains a stream, Box Elder Creek, that is approximately 3,500 linear feet (Figure 4). No other wetlands exist within the Project area. Vegetation above the OHWM consisted of smooth brome (Bromus iiermis), curly dock (Rumex cr/spus), eastern cottonwood (PopuIus deltoides) , and narrowleaf willow (Sa /ix exigua) . Vegetation below the OHWM consisted of narrowleaf cattail (Typha an rustifo//a). No threatened and endangered species habitat exist within the Project area. A nest was observed in the southern portion of the Project Area as noted on Figure 4. The nest is an active Swainson's Hawk nest that is located in a cottonwood tree near Box Elder Creek along the southern portion of the Project area. If construction will occur between April 1 and July 15, then a 1/4 -mile buffer seasonal restriction surrounding the nest should be adhered to prior to any clearing or grading activities occurring (CPW 008). Conclusion Olsson recommends avoiding impacts to Box Elder Creek for the DCP Crosstie Project. If the Project impacts Box Elder Creek (Figure 4), a Pre -Construction Notification will be required to the USACE and the Project will be able to proceed under a Nationwide Permit 9, A Nationwide Permit 39 has an impact limit of 0.5 acres of wetlands and 300 linear feet of stream bed. If impacts to stream bed are greater than 300 linear feet, an individual permit will be required. A mitigation plan will also be required if the Project impacts 300 linear feet or more of stream bed. Nationwide Permit General Conditions will also apply to the Project. 1525 Raleigh Street, Suite 400 TEL 303.237.2072 Denver, co 80204 FAX 303.237.2659 vvww.olssonassociates,corn OLSSON ASSOCIATES t Olsson further recommends avoiding design and construction in the FEMA floodplain. If the design were to encroach into the floodplain, a Weld County Flood lain Development Permit would be required. The design would also need to demonstrate no -rise, otherwise Conditional Letter of Map Revision (CLOAK) and Letter of Map Revision (LOMR) would needed. The CLOIVIR process typically takes 120-180 days after submittal to the Federal Emergency Management Agency (FERIA). To prepare the no -rise certification or CLOMR requires: • Hydraulic modeling. Since the floodplain is an A Zone, approximate floodplain, a hydraulic model probably does not exist. A model would be created to determine the pre -project and post -project Base Flood Elevations (BFEs). The model would be prepared using LiDar data, if it is available. Otherwise, on -the -ground survey topographic would be needed to develop the model cross sections and map the floodplain. Field survey would be needed for the culvert crossings and WCR 59 and WCR 50. • Structures would need to be elevated above the flood elevation. • On a similar project in Weld County, the County required a scour analysis to evaluate erosion concerns and to identify the material size needed to resist erosion. Material testing to find a material that met the gradation requirements to protect the g pad from erosion, andconstruction materials testing was provided to show the required material was placed with the required compaction.

Description/Scope of Work: The proposed Prairie Compressor Station is located on a gently sloping site draining generally to the northeast with an average grade of about 1-2 percent, towards Box Elder Creek. This creek drains into the South Platte River about 10 miles northeast of the site. The overall parcel is about 144.1 acres, of which 9.03 acres will be used for a natural gas compression station. Additionally, approximately S acres will be used temporarily for parking and a contractor lay -down yard.

Soil Types: Clay loam topped with 4" gravel (NRCS type D, upgraded to Type A due to gravel topping) 3. Current Drainage Conditions II Current Off -site to On -site Drainage: Currently, excess stormwater drains across the parcel from the southwest to the northeast. Minimal runoff enters the site from the west because it is intercepted by WCR 59 and directed into Box Elder Creek. Similarly, some stormwater enters the parcel from the south but it is largely directed around the site to the east by ditches running along an unimproved road (where WCR 50 would normally be located) which cuts through the middle of the site running east -west. Such conditions will not change as a result of this project. All of the local sheet flow that runs onto the parcel will be diverted around the project site, and eventually into Box Elder Creek. 3.2 Current On -site Drainage: Within the proposed compressor station area, stormwater runoff currently runs along east -west cultivated furrows and then to the northeast within Box Elder Creek, 3.3 Current On -site to Off -site Drainage: Runoff from the location of the proposed compressor station flows into Box Elder Creek, then off -site via the Creek to the northeast, and eventually into the South Platte River about 5 miles northeast of the site. 4. Proposed Drainage Conditions 4.1 Proposed Off -site to On -site Drainage: The existing conditions remain unchanged in this project, Only a minor amount of surface water enters the sitefrom the southwest, and is routed into Box Elder Creek without flowing into or through the proposed compressor station site. 4.2 Proposed On -site Drainage: In the proposed site development, the site will be graded generally flat, with a slight ridge running east -west along the center of the new process area. Water will flow on the surface both north and south away from this ridge so that runoff and winter snowmelt do not collect around the main process area. Runoff will be collected in shallow swales on the north and south sides of the process area, and those swales will drain to the new WQF pond at the northeast edge of the site, Swales will be located around the periphery of the plant in such a way as to convey runoff from all process areas associated with the compressor station into the WQF pond. 4.3 Proposed On -site to Off -site Drainage: 100% of the storm runoff from the process area will be collected in a new WQF/pond. The design of the new WQF/pond will be based on collecting 100% of a 100-yr,/i-h r duration storm. After the ra i n from a large storm, subsides, a DCP technician will check the water in the pond for any sheen indicative of any accidental hydrocarbon contamination. If any contamination is found, the contaminated water will be removed by DCP and hauled to a refinery for recycling. Non -contaminated water will be released via a normally closed manual valve to flow off -site in a controlled manner. The rate of water discharge is limited so as to not exceed the historical stormwater flow from the site, calculated from a 10-yr/i-hr storm based on the pre -development runoff factor of 2% imperviousness. Water will not be held for longer than 72 hours after capture in a rainstorm. Drainage off -site will continue to be routed to Box Elder Creek as previously. Page 3 5.

Calculate Full -flow Release Rate of Pond: Per Weld County Code, for nonnurbanizing areas, the release rate cannot exceed the historical 10-yr/i-hr release rate assuming 2% runoff coefficient, For normal operations and storms up to a 100-yr/1-hr storm, the pond will have a normally closed, manually opened gate valve on a 12" -diameter outlet pipe. An operator will drain the pond after checking for inadvertent contamination. Pond will not drain during the 100-yr/1-hr storm.

By lowering the gate valve about 95% flow will not exceed allowable maximum release rate. The required pond volume is 39,235 cft Time to drain (actual) Vreq / °rnaxallowable = 5 VD of rnax flow 40.24 hrs (OK since c 72 hrs max per state laws) Summary: The WOF will be emptied after a DCP technician checks for the presence of inadvertent contamination after the conclusion of the storm. Since the full flow through the irrigation gate valve on a 12" -diameter pipe exceeds the allowable flow rate per County standards, the opening will be reduced in size to slow down the flow. The reduced flow will still be large enough to drain the pond within 72 hours per state law. 94 Emergency Spillway Calculations For extreme rainfalls exceeding the 100-yr/1- h r criteria, the pond will be constructed with a rectangular concrete emergency spillway, with a sharp -edged drop-off of 4 feet for energy dissipation. The emergency, spillway will allow the full flow of a second 100-yr/i-hr storm to discharge over the top of the spillway, which will only occur after the W0F is full from an initial 100-yr/i-hr storm. Stated another way, the spillway is designed for a Factor of Safety of 2.0 compared to the 100-yr/I-hr storm rate. Required maximum flow over spillway: -eq = 4M7 cfs, as calculated for 100-yr/1-hr post -development flow in Section 5.3 Allowable emergency flow for a sharp -crested weir, at maximum allowable 6" deep flow: %How = Ce * i.e * He'3 where: Ctall,, TA allowable flow of stormwater over top of weir (cfs) Ce = coefficient of discharge from Handbook of Hydraulics, King . Brater = 3.2756 Le = effective length of crest {ft) = 8 ft He = depth of flow above crest (ft) set at 03 feet max for safety reasons* QUOIN = (keg < 0allawable 9.26 cfs, which is the rate that can safely pass over the spillway if required, so flow rate is OK *Note that the WOF and its associated emergency spillway are within security fences, and not publicly accessible. The base of the drop-off below the weir is reinforced concrete, and rip -rap will be installed downstream of the spillway to further reduce flow velocity, Also note that the emergency spillway, is designed to safely convey the flow from a second 100-yr/i-hr storm. Because we have oversized the pond, a portion of the second storm will be contained within the pond before the stormwater begins to flow over the spillway. By that time, the pair of 100 -year storms will have largely dissipated, and the outflow rate over the spillway will be well below the design capacity. Page 4 10.

Miscellaneous Design Considerations Miscellaneous culverts will be installed around the proposed site where needed for pedestrian and vehicular traffic during rainstorms. l _ I Erosion control best practices will be employed prior to construction in compliance with engineered drawings and a County Public Works Permit for grading of the site. After construction, permanent erosion control measures will be finalized, and the areas outside of the perimeter fence will be reseeded with native seed mixes or returned to irrigated agricultural production. 12. Operations and Maintenance Plan DCP's experience with other existing facilities in Weld County that have WON and concrete spillways with designs comparable to those proposed is that maintenance issues with these facilities are minimal. 1. Essentially 100% of the subbasin draining into the pond is graveled or roofed. There is minimal silt or clay that erodes off of the process area into the pond. We rarely need to de -silt the pond. However, if we did need to do so, the base of the area immediately upstream of the outlet is designed as a flat concrete slab and is accessible via a skid steer loader or backhoe which could remove the soil if necessary. 2. DCP's technicians keep the site within the fenced process area very clean for safety and fire protection reasons. We do not have much trash blowing around that would collect within the pond. There are occasional tumbleweeds that blow over the fence that can collect at the spillway, but those are manually removed as required. 3. For fire safety reasons, weeds within and around the periphery of the facility are controlled and removed as required. There is not a lot of dead plant material that can collect in the pond and spillway. 4. For safety and security reasons, the main process areas of the facility, as well as the proposed pond, are installed behind security fences designed to keep the public out of the facility. As a result, vandalism and theft within the fenced areas have not been much of a concern. This precludes theft or damage that might occur to the gate valve and associated hardware at the pond outfall. 5. If the pond were in a public venue, we might be concerned about damage to the day geotextile pond liner. Inside our fence, however, we do not have to worry about vehicular or pedestrian traffic that might damage the liner. 6. DCP does instruct its Operations group to drain the WQF's periodically after large rainstorms, This complies with state laws regarding permanently capturing runoff water, and it complies with DCP's internal goals of reducing the possibility of inadvertent contaminant spills leaving the property. 7. DCP has experienced staff and the necessary equipment to complete minor repairs to stocrnwater control facilities as needed. DCP also has continuing relationships with qualified general contractors to expedite major repairs if they are ever needed. In most cases, DCP technicians will touch up the grading every year or so to minimize erosion. The only moving part of the gate valve is the handle and screw to lift the gate, and it is easily accessible for lubrication when or if required. 8. DCP technicians inspect the entire area of the facility daily, and are trained to identify and correct any conditions which present safety or security concerns, and/or potential environmental problems, The Operating Procedures for each facility includes these types of regular inspections, along with a directive to the Operations staff to drain the WOE'S as needed after checking for potential contaminants. Also, see Section 6 of the Storm Water Management Plan. 13. Use of Mrs for Contamination Control Although it is not required by state or county laws, DCP prefers to use the WOF associated with this facility for an additional layer of control in the event of an inadvertent or accidental release of contamination from the facility. DCP's preferred practice for ponds such as this is to oversize each pond so that 100% of the runoff during a severe storm will be captured in the WQ.F pond, and will not be allowed to "flow through the pond during the storm. After the storm subsides, a DCP technician will inspect the pond for evidence of any accidental contamination. If no indication of contamination is found, the technician will open a normally closed valve to allow the WQF to drain over 72 hours. The delayed release reduces the severity of downstream flooding after a severe storm and reduces instances of siltation released from the project site. In addition to the normal release pipe, an emergency spillway is provided for storm flows in excess of 100 yre ar flow rates, The pond will have a bentonite ite geotextile liner to prevent infiltration into the soil below the pond, which is a precaution DCP takes to prevent infiltration of contaminants in the event of an inadvertant spill that will be captured by the pond. Page 6 14 Summary The design of the new WQf detention pond will be based on collecting 100% of the runoff predicted from a 100-yr/ 1 -hr• duration storm. After the rain from a large storm subsides, a plant operator will check the water in the pond for any sheen indicative of any accidental hydrocarbon contamination. If any contamination is found, the contaminated water will be removed by DCP and hauled to a refinery. Non - contaminated water will be released via a normally closed manual valve to flow off -site in a controlled manner, The rate of water discharge is limited so as to not exceed the historical stormwater flow from the site, Water will not be held on the site for longer than 72 hours after capture in a rainstorm, The historical flow patterns and runoff amounts will be maintained in such a manner that it will reasonably preserve the natural character of the area and prevent property damage of the type generally attributed to runoff rate and velocity increases, diversions, concentration and/or unplanned ponding of storm runoff from the 100 -year storm. There are no significant stormwater-related project impacts to cuff, site property that need to be mitigated.

Provide a proposed condition drainage map, showing the site area draining to the pond versus the portion of the drainage that is being routed around the site (if it is routed around the site). 4. Please address any off -site flows for the property. Off -site flows can either be routed around the site or be passed over the pond's emergency overflow spillway undetained. a. From the Grading Detail Plan, it appears that a small amount of off -site flows will be routed around the site and may end up in the pond. If they are tributary to the pond, include this volume in the emergency spillway flows. 5. Please provide additional calculations for the swales, culverts and other drainage infrastructure, including the culvert under the entrance road, north east of the site. Swales should be sized to convey the 100 -year developed flows to the pond plus freeboard. The requirement is a foot of freeboard for flows over 50 cfs. For flows under 50 cfs, 1.33 x the design flow may be used. 6. When calculating the weighted C value for the proposed site, please model the pond water surface area using a 100% impervious value. 7. The valve referenced in the report should be placed downstream of a restrictor/orifice plate sized for the 10 -year historic release rate or include detail in the drawings indicting how the valve will be restricted to only open as far as calculated in Section 8. Calculated Maximum Allowable Pond Outflow Rate via 12" Outflow Pipe (with Reduced Opening). 8. In Section 5.1, the C -values used are for Type A soils. Placing gravel on Type D soils does not make it a type A soil. Use Type D soils for calculations. The post development C values are incorrect for the 2017 USDCM manuals (the equations referenced). Please update the calculation with the pre development and post development impervious percentage C -value for D Soils (around 0.147 and 0.67 respectively). Subsequent sections of the report will also need to be updated with correct release rates and runoff values. 9. In Section 6.0, the pond volume was calculated using the site impervious percentage rather than the C -value for the proposed site impervious percentage. Please update the calculation. 10. In Section 10, I do not understand where the values are coming from for the Inflow rate. Please clarify. 11. Provide details of the outlet structure and the emergency overflow weir for the pond for construction. 12. In Section 3.1 the report mentions "(where WCR 50 would normally be located)" — please clarify. 13. In Section 5, the report refers to the detention pond as a "temporary" detention pond. Please clarify if this means that the pond will be on site temporarily or if the water will be detained temporarily. 14. Once the revised design and drainage report have been submitted, the County may provide additional comments in addition to the ones listed above. Depending on the complexity of the changes made, a full 28 -day review period may be required. 15. Please provide a written response on how the above comments have been addressed when resubmitting the drainage report.
