This USR application is organized in an order to address the requirements of: i) the USR required submittal items outlined under Section 23-2-510 of the County Code, and ii) the additional information as outlined in the pre - application meetings and summary letters as requested by County staff. 1.1 OVERALL PROJECT OVERVIEW The Boardwalk Pipeline Project, approved on December 14, 2016 by the Weld County Board of County Commissioners (USR16-0028) incorporates a 29.4 -mile natural gas gathering trunkline originating at a Central Delivery Point ("CDP") Facility located in the SW of Section 24, Township 1S, Range 67W in Adams County, Colorado to Discovery's Ft. Lupton Gas Plant located approximately 4.3 -miles northwest of Lochbuie, b u i e, Colorado in the SW of Section 11, Township 1N, Range 66W and approved on October 26, 2016 by the Weld County Board of County Commissioners (USR16-0031), where the gas is processed to recover natural gas liquids (SNGL")}s for delivery to a nearby third party via a 0.6 -mile NGL sales pipeline. Conversely, pipeline quality natural gas off the Ft. Lupton Gas Plant is delivered to a custody meter station for sales to a third -party transmission pipeline via a 1.4 -mile residue gas sales pipeline. Phase II of the Boardwalk Pipeline Project expands the original system west of the CDP facility with a new 20 - inch or smaller natural gas pipeline, 8 -inch crude oil pipeline, and 12 -inch or smaller water pipeline from a new pipeline pigging facility (Brighton West Interconnect Facility) located approximately 2,100 feet west from the intersection of E. 1521d Avenue and Holly Street on the north side of E-470 in Adams County and heading north approximately 4.5 miles before crossing into Weld County near the intersection of E. 168th Ave. / County Road 2 and Quebec Street. From the Adams County I Weld County line at E. 168'h Ave. I County Road 2, t h e proposed 20 -inch or smaller natural gas pipeline, 8 -inch crude oil pipeline, and 12 -inch or smaller water pipelines will continue north into Weld County approximately 0 82 miles where they will terminate at a new pigging facility. From the pigging facility, the 20 -inch or smaller natural gas pipeline will continue north by north east approximately 9.47 miles to a second pigging facility located approximately 1,100 ft. north of the intersection of County Road 29 and County Road 6, before continuing in a general north by northeast direction approximately 4.95 miles to the Discovery Ft.

Prepared By: ZION ENGINEERING, LLC Page 12 of 27 Rev A, May 2017 BOARDWALK PIPELINE PROJECT APPLICATION FOR USE BY SPECIAL REVIEW PERMIT 20 -INCH NATURAL GAS PIPELINE DISCOVERY DJ SERVICES, LLC Figure 2.2,2 - 20 -Inch or Smaller Natural Gas Trunkline Route Options The preferred route is shown in "Blue" above in Figure 2.2.2, while Alternative #1 and Alternative #2 are shown in "Magenta" and "Orange" respectively. While both alternatives offer a short, more direct route between the Brighton West Interconnect Facility, located in Adams County, and Discovery's existing Ft. Lupton Gas Plant located in Weld county; these alternatives are further from both existing and future planned well development and would thus yield longer interconnecting laterals from the respective well pads to facilitate delivery into the proposed trunkline, have a greater impact on nearby landowners and the general public in both Adams and Weld County, and have overall greater environmental impacts. Similar to the preferred route, construction activities for both Alternative #1 and Alternative #2 will have minimal, temporary and short term, effects on the residents, businesses and natural environment of Weld County. Table 2.2.2 below summarizes the respective route lengths and land affected by each alternative and the preferred route. Table 2.2.2 Project Alternatives Route Lengths & Land Affected, Weld County Route Acres of Land Affected (Based on 80' wide area of disturbance) Total Pipeline Length (miles) No. Road Crossings Alternative 1 Alternative 2 Preferred 127,0 acres 126.1 acres 13.1 13.0 3.2.2.1 ALTERNATIVE ROUTE #1 Alternative #1 routes north and west of the preferred route providing a total length of approximately 16.7 miles, with approximately 13.1 miles in Weld County. This Alternative would have the same originating point, located approximately 2,100 feet west from the intersection of E. 152nd Avenue and Holly Street on the north side of E-470 in Adams County, entering into Weld County approximately 125 ft east of the intersection of E. 168th Ave. I Prepared By: ZION ENGINEERING, LIC Page 13 of 27 Rev A, May 2017 BOARDWALK PIPELINE PROJECT 20 -INCH NATURAL GAS PIPELINE APPLICATION FOR USE BY SPECIAL REVIEW PERMIT DISCOVERY DJ SERVICES, LLC County Road 2 and Quebec Street. From the Weld County Line, this Alternative would travel north along Weld County Road 17 to a point approximately 2,600 ft. north of WCR 6 before turning east approximately 3 -miles to WCR 23 and then north to WCR 8 where the route would turn east, crossing the Platte River, U.S. Highway 85, and the BNSF railroad, before taking a general northeasterly alignment to Discovery's Ft. Lupton Gas Plant. This Alternative would incorporate an area of disturbance in Weld County approximately 18.1 miles long and 80 feet wide, or approximately 127.0 acres, with a permanent easement of 13.1 miles long and 50 feet wide, or approximately 79.4 acres. Route Maps for this Alternative are provided under Exhibit G.1 "Alternative Route 41 — Route Maps", 3.2.2.2 ALTERNATIVE ROUTE #2 Alternative #2 routes south and east of the preferred route providing a total length of approximately 16.5 miles, with approximately 13.0 miles in Weld County. This Alternative would have the same originating point, located approximately 2,100 feet west from the intersection of E. 152nd Avenue and Holly Street on the north side of E-470 in Adams County, entering into Weld County approximately 125 ft. east of the intersection of E. 168th Ave. / County Road 2 and Quebec Street. From the Weld County Line, this Alternative would travel east along E. 188th Ave. /County Road 2 approximately 3 -miles before turning north approximately 2 -miles, crossing WCR 23 and WCR 6 before turning east and crossing the Platte River, U.S. Highway 85, and the BNSF railroad and continuing in a general easterly direction to WCR 33 before turning north to Discovery's Ft. Lupton Gas Plant. This Alternative would incorporate an area of disturbance in Weld County approximately 13.0 miles long and 80 feet wide, or approximately 126.1 acres, with a permanent easement of 13.0 miles long and 50 feet wide, or approximately 78.9 acres. Route Maps for this Alternative are provided under Exhibit 6.2 "Alternative Route 2 Route Flaps". 3.21.8 AIR QUALITY ALTERNATIVES The short-term emission sources impacting air quality would be the same for both Alternatives and the preferred route and would include construction equipment, typically diesel driven, and traffic on the roadways and right-of-way. Both Alternative #1 and Alternative #2 are in the same airshed rs hed as the preferred route. While both Alternatives are slightly shorter and incorporate less disturbed area than the preferred route, both Alternatives would require approximately the same construction duration. Construction for either Alternative or the preferred route is anticipated to occur in late 3rd Quarter 2017 based upon the anticipated receipt of the required permits. Water suppression will be utilized to reduce the amount of dust generated during construction, as necessary. 3.2.2.4 PREFERRED ROUTE The preferred route originates approximately 2,100 feet west from the intersection of E. 152nd Avenue and Holly Street on the north side of E-470 in Adams County, and travels in a general northeast direction, entering Weld County approximately 125 ft. east of the intersection of E. 168th Ave. / County Road 2 and Quebec Street. From the Weld County Line, the route continues north following parcel boundaries approximately 0.89 miles to the proposed Brighton West Pigging Facility. From there, the route travels north through agricultural fields approximately 2.8 miles to County Road 8 before turning east approximately 0.9 miles and then traveling in a general southeasterly direction to County Road 6 and crossing the Platte River, U.S. Highway 85, and BNSF railroad and continuing in a general easterly direction to WCR 29, before taking a general northeasterly alignment to Discovery's Ft. Lupton Gas Plant. The preferred route would incorporate an area of disturbance of approximately 15.2 miles long and 80 feet wide, or approximately 417.8 acres, with a permanent easement 15.2 miles long and 30 feet wide, or approximately 92.1 acres. While this route is longer in distance than the Alternatives considered, the route bypasses the more populated areas of unincorporated Weld County, taking local landowner preferences into account and providing Prepared By: ZION ENGINEERING, LLC Page 14 of 27 Rev A, May 2017 BOARDWALK PIPELINE PROJECT 20 -INCH NATURAL GAS PIPELINE APPLICATION FOR USE BY SPECIAL REVIEW PERMIT DISCOVERY DJ SERVICES, LLC a mitigated impact to local businesses and residential areas. Route Maps for the preferred route are provided under Exhibit G.3 "Preferred Route - Route Maps". A list of the parcels along the preferred route within Weld County on which the pipelines will be located is provided under Exhibit H "Weld County Line List". 3.2.2.5 PREFERRED ROUTE CONSIDERATIONS & REASONING The preferred route was selected to mitigate the impacts to local businesses and residential neighborhoods; conform with the comprehensive plans for Adams County, Weld County, the cities of Thornton and Ft. Lupton; minimize impacts to the environment; and to the greatest degree possible, the preferences of local city and county landowners. The preferred route is located on lands within Weld County that are zoned as agricultural, Industrial, and PUD. In selection of the preferred route, Discovery considered the Weld County Comprehensive Plan along with the current and future development plans for the City of Ft. Lupton. In addition, in areas zoned for Agricultural, Discovery has worked with the applicable property owners to accommodate their considerations and preferences for the route and develop the preferred alignment to mitigate impacts to actively cultivated fields and productive areas. The preferred route does cross various canals associated with regional drainage and irrigation, including the German Ditch and Fulton Canal systems. Discovery will plan to cross these canals via bore or horizontal direction drill, in accordance with the respective canal company requirements. Permit applications for these crossings, and other crossings along the preferred route, including permits with CDOT for U.S. Highway 85 and BNSF for the railroad crossings, 3.2.3 MITIGATING MEASURES & TECHNIQUES Procedures to be employed in mitigating any adverse impacts of the proposed routes or sites. All pipelines will be buried to provide 48 -inches of cover. The pipeline trench will be excavated mechanically; pipe segments will then be strung along the ditch line and then welded together using welders and weld procedures qualified under the requirements of the Code of Federal Regulations; each weld will be examined utilizing industry standard non-destructive examination, or x-ray, procedures by qualified technicians; the coating on the pipeline will be inspected for damage and repaired as necessary and then the line(s) will be lowered into the trench and backfilled. The pipeline(s) will subsequently be pressure tested using water (hydrostatically tested) to industry regulations. All available topsoil will be conserved through a process known as "double -ditching", which excavates and removes and conserves topsoil where practical. Conserved topsoil will be windrowed separately from the underlying subsoil and stored along the construction right-of-way until the trench is backfilled, unless construction occurs during the winter with frozen soils. Under frozen soil conditions, topsoil salvage may be conserved using the following Best Management Practices BM P" 's: 1) topsoil would be ripped to a depth of 6 inches prior to stripping to allow for effective separation from the subsoil; and 2) topsoil would be sheared off from the subsoil layer to approximately 6 inches using appropriate equipment to accomplish topsoil salvage without mixing. Prior to construction, a Stormwater Management Plan ("SWMP") will be prepared to address storrriwater and erosion control during construction activities. Stormwater Best Management Practices (aBM P")'s will be installed for the construction phase in accordance with the requirements of the SWMP. Erosion control BMP's will include, but not be limited to, silt fencing, straw wattles, hay bales, or combinations of these items, depending on the area requiring erosion control during construction, Construction staking will occur to designate the pipeline centerlines and outside construction right-of- way boundaries. The limits of disturbance will be clearly marked I staked prior to construction including the construction right-of-way, temporary use areas / work space, and access roads. Utility lines will be located and marked to prevent accidental damage during pipeline construction. Sensitive areas to be protected from disturbance or that require monitoring will be indicated on engineering documents and construction drawings and staked and marked accordingly in the field prior to construction. The location of access road entry points will be properly marked. Flagging, signs, and other markings Prepared By: 0/4 certe ZION ENGINEERING, LLC Page 15 of 27 Rev A, May 2017 BOARDWALK PIPELINE PROJECT 20 -INCH NATURAL GAS PIPELINE APPLICATION FOR USE BY SPECIAL REVIEW PERMIT DISCOVERY DJ SERVICES, LLC identifying the limits of disturbance would be maintained through all phases of construction. A survey crew would be available during construction to replace any stakes that have been damaged or inadvertently removed. Wildlife and High Interest.Species: Wildlife and high interest species surveys will be performed prior to construction and the applicable agencies consulted. This shall include: A Raptor nest survey will be completed if pipeline construction extends or is scheduled for the raptor nesting season (January 15 to July 31), If active raptor nests are found near the ROW (within 0.3 miles) the CDPW will be consulted to determine if any nest protection measures are needed. • • * *• A nesting Burrowing Owl Survey will be completed if any black -tailed prairie dog towns are crossed during the period of owl activity (March 15 to October 31). If nesting burrowing owls are located consultations would occur with the CDPW to determine if any nest protection measures are needed. A Ute ladies' tresses orchid and Colorado butterfly plant survey would be completed in all wetlands that are proposed to be crossed by trenching. This survey would be completed during the plants blooming period (late July through August). If either species is located consultation would occur with the USFWS. The Colorado Parks and Wildlife District Wildlife Manager for the area will be consulted prior to construction. If there any issues of wildlife mortality (entrapment in the trench, or other mortality) the District Wildlife Manager will be notified. Archeology and Paleontolggy: On call archeologist and paleontologist would be available to consult if any potential archeological (stone tools, fire rings, foundations, bones) or paleontological (fossils) are found during construction/excavation of the trench and ROW. Project construction would be temporarily stopped until review by the archeologist/paleontologist. If needed the State Historic Preservation Office (' HPO") would be consulted. Impacts to historic canal/ditch crossings would be avoided by completing these crossings by horizontal directional drill ("HDD"). DD") . M.obiliation:. Construction equipment will be transported to the construction right-of-way via tractor trailer and unloaded within designated staging area(s). Transportation equipment will be removed from the site or parked within a staging area once off-loading is completed. Clearing and + radin,g: Vegetation will be cleared and the construction right-of-way would be graded, to the degree necessary, to provide for safe and efficient operation of construction equipment and vehicles and to provide space for the storage of subsoil and topsoil. Construction activity and ground disturbance will be limited to approved, staked areas. Where required, trees will be cut with a chain saw and/or mechanical shears and brush would generally be cut with a hydro -axe or similar equipment. Trees and brush will be cut as close to the ground as possible. Vegetative material will typically be shredded and scattered back across the surface to increase roughness, facilitate seeding establishment, and protect the construction right-of-way. Stumps that are not shredded or chipped and that are incorporated into the topsoil will be removed and disposed of at an approved disposal facility. Vegetation may also be brush -hogged to preserve habitat. Topsoil will be stockpiled separately from subsoil and will not be used to pad the trench or construct trench breakers. In areas where the construction right-of-way crosses ephemeral drainages, the drainages will not be blocked with topsoil or subsoil piles. Topsoil and subsoil would be placed on the banks of the drainages. Gaps will be left periodically in the topsoil and subsoil piles to avoid ponding and excess diversion of natural runoff during storm events. Trenching_ Trenching will be completed using track hoes or a mechanical trenching machine. The pipeline trench will be to one side of the construction right-of-way to allow for spoil to be placed opposite of the wider working side. It is not anticipated that blasting will be required during pipeline construction. Prepared By: Page 16 of 27 Rev A, May 2017 ZION ENGINEERING, LLC BOARDWALK PIPELINE PROJECT 20 -INCH NATURAL GAS PIPELINE APPLICATION FOR USE BY SPECIAL REVIEW PERMIT DISCOVERY DJ SERVICES, LLC Access will be provided for landowners and grazing rights holders to move vehicles, equipment, and livestock across the trench where necessary and consistent with prior agreement with landowners. Livestock operators will be contacted and adequate crossing facilities would be provided as needed to ensure livestock are not prevented from reaching water sources because of the open trench. The contractor will keep wildlife and livestock trails open and passable by adding soft plugs (areas where the trench is excavated and replaced with minimal compaction) during construction. Soft plugs with ramps on either side will be left at all well-defined livestock and wildlife trails and at no more than 0.5 -mile intervals along the open trench to allow passage across the trench and to provide a means of escape for livestock and wildlife that may fall into the trench. Trench breakers constructed of sand bags or polyurethane foam will be installed at specific spacing intervals to impede shallow groundwater from flowing down the trench. Lowering -ire are _I _ ih i. Before the pipe section is lowered into the trench, an inspection will be conducted to verify that the pipe is properly fitted and installed in the trench, minimum cover is provided, and the trench bottom is free of rocks and other debris that could damage the external pipe coating. The pipe sections will be simultaneously lifted in position over the trench and lowered in place. Sifted soil fines from the excavated subsoil will provide rock -free pipeline padding and bedding. Sandbags may be used to pad the bottom of the trench instead of, or in combination with, padding with soil fines. In rocky areas, padding material or a rock shield will be used to protect the pipe and coating. Topsoil will not be used to pad the pipe. Backfilling Pipeline: Shading and backfill will begin after a section of pipe has been successfully placed in the trench, inspected, and approved for backfill. Backfill will be conducted using a bulldozer or other suitable equipment. Subsoil excavated from the trench will generally be used to backfill the trench, except in rocky areas where imported select fill material may be needed. Backfill will be graded a n d compacted, where necessary, for ground stability, by tamping or walking with a wheeled or tracked vehicle. Compaction will be conducted to the extent that there would be no voids in the trench. Any excavated materials or materials unfit for backfill will either be utilized elsewhere or properly disposed of in accordance with applicable laws, regulations and landowner agreements. Cleanup and, Restojaon. Cleanup and restoration will occur after the pipeline is installed and backfill is completed, or in the spring following construction if weather conditions would inhibit the proper restoration activities, to minimize the length of time that the open trench and un-stabilized right-of-way is present. Cleanup of the surface along the construction right-of-way will include removal of construction debris and final grading to the finished contours. Permanent erosion control measures will be installed as required and seeding would occur in accordance with landowner requirements. Invasive and noxious weeds will be controlled after construction until the right-of-way is restored. Road Crossings_ All county road crossings will be completed by conventional bore or directional drill methodology with sufficient depth to maintain a minimum of 60 -inches of cover at the lowest bar ditch. Waterbody Crossings: All streams and named ditch / canal crossings will be completed via HDD to avoid disturbance of the stream and ditch bed and banks. Each HDD will begin, end and be of sufficient depth to ensure the pipeline is not subject to the hazard of stream scour during anticipated flood events. If the HDD crossing avoids impact to all associated wetlands, a U.S. Army Corps of Engineers (USACE) 404 permit will not be necessary for this crossing. In areas with trenched wetland crossings, the construction right-of-way will be reduced from 80 feet in width to 50 feet.in width, where only the ditch line will be topsoiled and the drive space will be matted with pipeline mats to mitigate disturbance. Blading would occur only over the trench line and the construction traffic / access area would be matted to avoid vegetation disturbance. If standard open cut construction methods are used in wetland areas, Discovery will obtain the necessary ACC E 404 permits. 3.2.4 PROJECT DESIGN, PERMITTING, CONSTRUCTION & COMMISSIONING SCHEDULE An outline of the planned construction, including startup and commissioning schedule, to include the number of stages and timing of each.

Discovery plans to begin construction in Weld County once all permits are received and the required land and right-of-way is acquired. Following completion of construction, Discovery will commission the respective pipelines and associated facilities and place the Project in-service. Overall, the non -construction activities are anticipated to take approximately 4-6 months, followed by approximately 3-4 months of construction and 1-2 weeks of commissioning. 3.2.5 NEIGHBORHOOD MEETING Information of any public meeting conducted, to include the location, date, time, attendance and method of advertising. Pursuant to discussions during the pre -application meeting on January 13, 2017, Discovery conducted a neighborhood meeting to inform property owners located within 250 feet of the preferred pipeline permanent right-of-way (ROW") about the Project. A copy of the surrounding property owner notification list incorporating the names, addresses, and the corresponding parcel information of all property owners within 250 feet of the proposed pipeline right-of-way has been provided under Exhibit J "Sur�rountir q__I�r�o_ erty Owner Notifications List". The list was created from the Assessor records of Weld County and is current as of February 17, 2017. The neighborhood meeting was held on Wednesday, March 8, 2017 at the Eagle View Adult Center, located in Brighton, Colorado. Notification of the neighborhood meeting was mailed to all identified property owners within 250 feet of the Project on February 17, 2017. A copy of the notification brochure, along with the required summary of the neighborhood meeting is provided under Exhibit K 'NeiObernood, Meeting Notification & Summary" 3.2.6 DESCRIPTION OF HAZARDS A description of the hazards, if any, of fire, explosion and other dangers to the health, safety and welfare of employees and the genera/ PUBLIC. Prepared By: it ZION ENGINEERING, LLC Page 18 of 27 Rev A, May 2017 BOARDWALK PIPELINE PROJECT APPLICATION FOR USE BY SPECIAL REVIEW PERMIT 20 -INCH NATURAL GAS PIPELINE DISCOVERY DJ SERVICES, LLC The transportation of natural gas and other hazardous materials via pipeline is generally safer than other potential modes of transport. There is some small risk of an accident in which the integrity of the pipeline may be compromised resulting in a release of natural gas or natural gas liquids. Wet natural gas contains condensed forms of heavier natural gas liquids and produced water and is considered both flammable and combustible. Dry natural gas is a clean burning fuel source, also considered both flammable and combustible. In general, signs of a pipeline leak, include dead or discolored vegetation that is otherwise green along the pipeline right-of-way, along with pools of liquid or clouds of vapor or mist not usually present, Discovery will clearly mark the pipeline centerline with markers placed at line of site intervals and at all road, railroad and canal crossings. The markers will clearly identify the pipeline, and will provide a telephone number and address where a company representative can be reached in an emergency or prior to any excavation in the area. Discovery will also participate in the Colorado "One Call" system, which serves as a clearinghouse for excavation activities that are planned close to pipelines and other underground utilities. Discovery employs highly trained operators and contractors and maintains close working relationship with all emergency response personnel. 3.2.7 DESCRIPTION OF EMERGENCY PROCEDURES A description of emergency procedures to be followed in case of a reported failure or accident involving the proposed PIPELINE. Such outline shall include actions, if any, required of PUBLIC officials, including fire and police officials, and the names and telephone numbers of appropriate company officials to notify if an accident or failure should occur. Each respective pipeline centerline will be clearly identified with markers placed at line of sight intervals and at all road, railroad and canal crossings. These markers will clearly identify Discovery as the owner / operator, provide a telephone number and address where a company representative can be reached in an emergency. In the event of an emergency, a call to the number on these markers will go to Discovery's operations and control center located at the gas compression and processing facility. This facility will be staffed 24 hours / day, 7 days I week, 365 days/year by trained operators, qualified in both the day-to-day operation of the respective pipelines and associated facilities, but in emergency response procedures. These operators will also have the ability to monitor the operation of the pipeline system through a Supervisory Control and Data Acquisition ("SCADA") system. Through the SCADA system, operators will be able to see key parameters associated with the operation of the respective pipelines, including pressure, temperature, and flow rate. In the event that these parameters, or other critically identified criteria fall outside of pre -determined normal operating allowances, the SCADA system will raise warnings of potential operational upsets or pending emergency conditions, providing the operator with time to make corrections, if possible, to the system operation in order to clear the warning. In the event that the specified parameters, or critically identified criteria reach pre -determined setpoints within the system operation, the SCADA system will alarm. Upon notification of an emergency, either through the public emergency call number, SCADA system, operator inspection and training, or other originating source, Discovery will have the ability to isolate the respective pipelines by closing remotely operated valves at either end of the pipeline or, on t h e natural gas gathering trunkline, in e, at the three (3) remote pigging facility valves located along the line to isolate any potential fuel source and mitigate propagation of the emergency situation. In addition, Discovery operations personnel will have the ability to locally evacuate the natural gas pipeline via blowdowns located at each end of the line and at each respective remote pigging facility site. Depending upon the nature of the emergency, local emergency responders would be notified, and Discovery would implement their internal safety response procedures, including dispatching trained personnel to the site of the emergency. The specified emergency contact number for Discovery's Ft. Lupton Gas Plant has not yet been determined, but will be provided to the County and appropriate local emergency responders prior to commissioning of the Phase I pipeline system, and confirmed prior to commissioning of the Phase II pipeline system under this USR application. In the mean -time, emergency notifications or inquiries Prepared By: eit>d ZION ENGINEERING, LLC Page 19 of 27 Rev A, May 2017 BOARDWALK PIPELINE PROJECT 20 -INCH NATURAL GAS PIPELINE APPLICATION FOR USE BY SPECIAL REVIEW PERMIT DISCOVERY DJ SERVICES, LLC during construction of the project can be directed to Discovery's Project Manager, or on -site Construction Manager as provided below: 3.2.7.1 PROJECT MANAGER Cory Jordan Discovery DJ Services, LLC 7859 Walnut Hill Lane, Suite 335 Dallas, TX 75230 (318) 272-1018 3.2.7.2 CONSTRUCTION MANAGER Jeff Brewster Quality Check Energy Services, LLC 562 north 7th avenue Brighton, CO 80601 (318) 348-7693 3 2.8 MITIGATING MEASURES TO IMPACTS ON IRRIGATED AGRICULTURAL LANDS A description of the method or procedures to be employed to avoid or minimize the impacts on irrigated agricultural land. Discovery has worked with each respective landowner to develop the preferred alignment to mitigate impacts to irrigated and / or actively cultivated fields and productive areas. The impacts to these lands will in addition be further mitigated by: ••# Minimizing the construction right-of-way and associated surface disturbance to the degree possible; • Routing the pipeline so -as to avoid affecting the operation of irrigation equipment; • Segregating topsoil from excavated spoils to facilitate subsequent restoration following construction; •:* Following construction of the pipeline, the ROW will be seeded or left fallow in accordance with the agreed individual landowner reclamation procedures. 3.2.9 CONFORMANCE TO WELD COUNTY CODE, CHAPTER 22 OF THE COMPREHENSIVE PLAN A discussion of how the proposal conforms with the guidelines of Chapter 22 of this Code and any other applicable code provision or ordinance in effect. Section 22-2-10(D) of the Weld County Code states that "extraction of natural resources is an important part of the economy of the County." These proposed pipelines will contribute to the expansion of the County's industrial economic base by providing increased capacity for future marketing of natural gas and crude oil production in Weld County. Additionally, Section 22-5-100 (A) states that a County goal is to "promote the reasonable and orderly exploration and development of oil and gas mineral resources." Per Chapter 22 of the Code, oil and gas facilities are allowed as a use by right in the A (Agricultural) zone district, in which the majority of the properties along the proposed pipeline routes are zoned. In addition, Weld County Code Section 23-2-200 et seq. permits construction of oil and gas support and service facilities in agricultural zoned districts. Section 22-5- 90 of the Weld County Code Comprehensive Plan states: The most efficient and environmentally friendly way to transport crude oil is by pipeline, rather than by truck. Transportation of the product by pipeline has less impact on County roads. Less truck traffic also benefits air quality in the area". Weld County Code Section 22-5-100 further states: "Oil and gas activities should be planned to accommodate current and future subdivision activities to the extent such development can reasonably be anticipated". Prepared By: ZION ENGINEERING, LLC Page 20 of 27 Rev A. May 2017 BOARDWALK PIPELINE PROJECT 20 -INCH NATURAL GAS PIPELINE APPLICATION FOR USE BY SPECIAL REVIEW PERMIT DISCOVERY DJ SERVICES, LLC The proposed pipelines meet the objectives outline in the Weld County Code Comprehensive Plan without rezoning or changing the use of the land. The pipelines will be buried beneath the ground's surface and therefore the effect on any active agriculture will be temporary and isolated to the construction phase of the project. Following construction, the surface along the pipeline right-of-way will be restored to its prior condition, and agricultural activities may resume. 3.2.10 DECOMMISSIONING PLAN A Decommissioning Plan. During operation of the pipelines, should it become necessary to decommission a portion of a line for maintenance or repair activities, pressure on the pipeline would be reduced to a safe operating pressure, or completely blown down utilizing blowdown valves at the respective remote pigging facility sites or either end of the pipeline. Liquids on the crude oil pipeline would be displaced utilizing a pipeline pig propelled with dry air, nitrogen, water or other approved inert material. All decommissioning activities would be performed using written procedures designed for the specific requirements and situation. As part of the decommissioning plan, all local emergency responders would be notified in advance and affected landowners notified, as necessary. There is no intention of ceasing operations of the respective pipelines once they are operational. However, in the event that any portion of the pipeline system is permanently decommissioned, that portion will be evacuated, cleaned, isolated, and abandoned in place or removed per all State and local regulations and per the respective landowner agreements. 3.2.11 DESCRIPTION OF HAUL ROUTES A description of any haul routes during construction, identifying the roads and bridges involved and the weight of the loads. Staging for construction in Weld County will be performed from Discovery's Ft. Lupton Gas Plant (USR16-0031). It is anticipated that the construction contractor will mobilize their equipment to the staging area utilizing U.S. Highway 85 or Colorado Interstate 76 followed by County Road 12 % / Highway 52 and then south on UVCR 35 to the temporary staging area. Construction equipment will be transported utilizing semi -tractor and flatbed trailers, or comparable equipment, with gross vehicle weights estimated at 40,000 — 80,000 lbs. Pipe for the construction of the respective pipelines will be strung directly to the right-of-way from the applicable pipe supplier. The main haul routes will incorporate Highway 85, Colorado Interstate 76, W R 2 / E. 168th Ave., WCR 6, WCR 19 and WCR 23. From the respective state and county roads, stringing trucks will access the pipeline right-of-way utilizing temporary access drives at the respective pipeline crossing locations outlined under Table 1.2.1 a above, and off WCR 6. The estimated maximum gross vehicle weight for a loaded stringing truck with 20 -Inch pipe will be between 71,000 — 77!000 lbs. In addition, construction personnel utilizing 1 -ton pick-up trucks and comparable sized vehicles will access the right-of-way utilizing similar ingress / egress routes. The expected haul routes include both Colorado Department of Transportation ("COOT") highways and Weld County roads. Upon review of the Weld County Restricted Bridge Locations Map, dated October 2016, it was determined that the project area does not incorporate any restricted bridges. Similarly, the current state of COOT roads and bridges for the proposed haul routes were reviewed utilizing the Colorado Department of Transportation's Online Transportation Information System, Highway Data Explorer. The findings of this review are outlined below and on the following pages. 3.2.11.1 US Highway 52: The main routes were selected starting with US Highway 52 / WCR 12 z as shown in Figure 2.2.11.1 on the following page.

The following federal and state permits will be required for the Project: Federal Permits: Army Corps of Engineers (ACOE) • • The proposed pipelines will cross several wetland areas, ditches and streams that are under the jurisdiction of the ACOE. Generally, pipeline construction does not result in the permanent fill of wetlands or waters of the U.S. Pipeline construction results in a temporary disturbance without loss or long term impacts. The Project should fall within the Nationwide Permit (Nationwide Permit #12) guidelines with the ACOE. Nationwide permits are regulated under Section 404 of the Clean Water Act. Required mitigation activities include removing all excess materials at wetland and stream crossings; stockpiling and restoring topsoil; and restoration of the wetland or stream channel to pre - construction conditions and contours.

Prepared By: 4 ZION ENGINEERING, LLC Page 27 of 27 Rev A, May 2017 SITE SPECIFIC DEVELOPMENT PLAN AND USE BY SPECIAL REVIEW (USR) QUESTIONNAIRE The following questions are to be answered and submitted as part of the USR application. If a question does not pertain to your use, please respond with "not applicable", with an explanation as to why the question is not applicable. Planning Questions 1. Explain, in detail, the proposed use of the property Response: The Project will incorporate three (3) pipelines that will require easements within Weld County: 1) A 0-inchor smaller, natural cas ciathering trunkline. The natural gas trunkline will originate at Discovery's new Brighton West Interconnect pigging facility located in the SWSE of Section 7, Township 1S, Range 67W, approximately 2,100 feet west from the intersection of E. 152nd Avenue and Holly Street on the north side of E-470 in Adams County, Colorado and will transport wet natural gas via a new 19.5 mile trunkline north to Discovery's Ft. Lupton Gas Plant (USR2018-0031) located approximately 4.3 miles northwest of the town of Lockbuie, Colorado in the SW of Section 11, Township 1N, Range 66W. The trunkline will enter Weld County via a bored crossing of E. 168th Ave. / County Road 2 in Section 33, Township 1 NI, Range 67W near the intersection of E. 168th Ave. / County Road 2 and Quebec Street. From the Weld County Line, the trunkline continues north following parcel boundaries approximately 0.89 miles to Discovery's proposed Brighton West Pigging Facility incorporated under this USR application. From there, the route travels north through agricultural fields approximately 2.8 miles to County Road 8 before turning east approximately 0.9 miles and then traveling in a general southeasterly direction to County Road 6 and crossing the Platte River, I.J.S. Highway 85, and BNSF railroad and continuing in a general easterly direction to WCR 29, before taking a general northeasterly alignment to Discovery's Ft. Lupton Gas Plant. The 20 -inch, or smaller, natural gas gathering trunkline will be constructed within the following Township, Range and Sections: 33-67-01, 28-67-01, 27-67-01, 22-67-01, 15-67-01, 14-67-01, 23- 67-01, 24-67-01, 19-66-01, 20-66-01, 21-66-01, 22-66-01, 15-66-01, 14-66-01, 11-05-01 and will incorporate the acquisition of a 50 ft. permanent easement plus 30 ft. temporary construction easement providing for a total 80 ft. construction right-of-way. 2) An 8 -inch crude oil pipeline. The crude oil pipeline will originate at the proposed Brighton West Pigging Facility located in the SENW of Section 33, Township 1N, Range 67W and will transport produced crude oil via a new 5.19 mile pipeline south to Discovery's proposed Brighton West Interconnect located in the SWSE of Section 7, Township 1S, Range 67W, approximately 2,100 feet west from the intersection of E. 152nd Avenue and Holly Street on the north side of E-470 in Adams County, Colorado where it will be delivered into Discovery's crude oil pipeline system and transported north to Platteville, Colorado for subsequent sales to regional markets. The 8 -inch crude oil pipeline will be constructed within the following Township, Range and Sections: 33-67-01 and will be placed within the same 50 ft. permanent easement as the 20 -inch, or smaller, natural gas gathering trunkline. 3) A 12 -inch, or smaller,_ produced water pipeline. The produced water pipeline will originate at the Ward Petroleum's Ivey West well pad located in the SE of Section 11, Township 1S, Range 68W approximately 1,600 ft. southwest of the intersection of E. 152nd Ave. and the eastbound E-470 ramp and travel in a general easterly direction along the E-470 multi -use corridor to Discovery's new Brighton West Interconnect pigging facility located in the SWSE of Section 7, Township 15, Range 67W, approximately 2,100 feet west from the intersection of E. 152nd Avenue and Holly Street on the north side of E-470 in Adams County, Colorado before continuing north, entering into Weld County near the intersection of E. 158th Ave. / County Road 2 and Quebec Street and continuing approximately 0.89 miles to the proposed Brighton West Pigging Facility located in the SENW of Section 33, Township 1N, Range 67W where the line will be capped for future use. The 12 -inch, or smaller, produced water pipeline will be constructed within the following Township, Range and Sections: 33-67-01 and will be placed within the same 50 ft. permanent easement as the 20 -inch, or smaller, natural gas gathering trunkline and 6 -inch crude oil pipeline. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. Response: Section 22-2-10(D) of the Weld County Code states that "extraction of natural resources is an important part of the economy of the County." These proposed pipelines will contribute to the expansion of the County's industrial economic base by providing increased capacity for future marketing of natural gas and crude oil production in Weld County. Additionally, Section 22-5-100 (A) states that a County goal is to "promote the reasonable and orderly exploration and development of oil and gas mineral resources." Per Chapter 22 of the Code, oil and gas facilities are allowed as a use by right in the A (Agricultural) zone district, in which the majority of the properties along the proposed pipeline routes are zoned. In addition, Weld County Code Section 23-2-200 et seq. permits construction of oil and gas support and service facilities in agricultural zoned districts. Section 22-5-90 of the Weld County Code Comprehensive Plan states: "The most efficient and environmentally friendly way to transport crude oil is by pipeline, rather than by truck, Transportation of the product by pipeline has less impact on County roads. Less truck traffic also benefits air quality in the area". Weld County Code Section 22-5-100 further states: "Oil and gas activities should be planned to accommodate current and future subdivision activities to the extent such development can reasonably be anticipated". The proposed pipelines meet the objectives outline in the Weld County Code Comprehensive Plan without rezoning or changing the use of the land. The pipelines will be buried beneath the ground's surface and therefore the effect on any active agriculture will be temporary and isolated to the construction phase of the project. Following construction, the surface along the pipeline right-of-way will be restored to its prior condition, and agricultural activities may resume. However, oil and gas pipelines require a Use by Special Review (USR) permit in Weld County. 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. Response: Weld County Code Section 23-3-20 identifies that oil and gas production infrastructure is allowed as a use by right in agricultural zone districts. The pipelines are located primarily within the agricultural zone district, and such zoning allow oil and gas support and service infrastructure such as pipelines. Any impacts to actively cultivated land by the project will be temporary, and agricultural operations can resume once the pipelines are operational. Section 23-3-40 also indicated that Oil and Gas Support and Service Facilities are acceptable as a Use by Special Review in the district. Describe what type of land uses surround the site. Explain how the proposed use is consistent and compatible with surrounding land uses. Response: The respective pipeline routes are primarily located in unincorporated Weld County in the agricultural zone district. The area surrounding the pipelines primarily consist of plowed fields, pivot irrigation system, County Estates and industrial complexes. The project is consistent and compatible with the surrounding land uses as a use allowed by right under Weld County Code Section 23-3-20. 5 What are the hours and days of operation? (e.g. Monday thru Friday 8:00 a.m. to 5:00 p.m.) Response: The hours of operation for the respective pipelines will be 24 hours per day, 7 days per week, 365 days per year. 6. List the number of full time and/or part time employees proposed to work at this site. Response: The operation and maintenance of the pipelines will be performed by trained and qualified operators and pipeline technicians stationed at Discovery's Ft. Lupton Gas Plant (USR10- 0031). There will be approximately 7-10 full-time employees working out of gas plant, with two shifts per day anticipated. The day shift will have approximately 6-8 full time employees, followed by a night shift with a single operator on duty. Shift hours have yet to be confirmed, but a typical shift rotation may be 6 a.m. to 6 p.m. 7 If shift work is proposed include the number of employees per shift. Response: See Response to Planning Question No. 6 above. List the number of people who will use this site. Include contractors, truck drivers, customers, volunteers, etc. Response: During construction, approximately 50-75 construction personnel, including the construction contractor and Discovery's construction management team, will be required to construct the pipeline along the right-of-way. Following construction! the respective pipelines will be operated and maintained by approximately 6-12 people per day, including full time employees, contractors and third party truck drivers. 9 If this is a dairy, livestock confinement operation, kennel, etc., list the number and type of animals. Response: There will be no animals on site. 10 Describe the type of lot surface and the square footage of each type. (e.g. asphalt, gravel, landscaping, dirt, grass, buildings) Response: Not Applicable. 11 How many parking spaces are proposed? How many handicapped (ADA) parking spaces are proposed? Response: Not Applicable. 12. Explain the existing and proposed landscaping for the site, Response,: Following construction, the right-of-way and all disturbed areas will be restored to their pre -construction conditions and contours. Agricultural land will return to agricultural uses, native grassland habitats would be reseeded. Similarly, all wetland areas will be restored to pre - construction conditions and contours, topsoil will be replaced and the wetland will be reseeded. Wetlands should return to preconstruction conditions within 1-2 growing seasons. Permanent erosion control measures will be installed as required and seeding would occur in accordance with landowner requirements. Invasive and noxious weeds will be controlled after construction to minimize further propagation pursuant to Chapter 15, Articles I and II of the Weld County Code, until the right-of-way is restored. No additional landscaping is proposed. 13. Describe the type of fence proposed for the site (e.g. 6 foot chain link with earth tone slats) ,Response: oU$a: Only fencing around the two (2) respective pigging facilities will be required. These locations will be enclosed with a 6 -foot tall chain link fence plus 2 -foot outrigger and 3 -strands of barbed wire and will incorporate a 20 -foot drive gate for access. 14. Describe the proposed screening for all parking and outdoor storage areas. If the site is located in a floodplain la i n outdoor storage is restricted. Response: No permanent parking or storage areas will be required. 15. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. Response: During operation of the pipeline, should it become necessary to decommission a portion of the line for maintenance or repair activities, pressure on the pipeline would be reduced to a safe operating pressure, or completely blowndown utilizing blowdown valves at the respective pigging facility sites or either end of the pipeline. Liquids on the crude oil and / or produced water pipelines would be displaced utilizing a pipeline pig propelled with dry air, nitrogen, water or other approved inert material. Al! decommissioning activities would be performed using written procedures designed for the specific requirements and situation. As part of the decommissioning plan, all local emergency responders would be notified in advance and affected landowners notified, as necessary. There is no intention of ceasing operations of the respective pipelines once they are operational. However, in the event that any portion of the pipeline system is permanently decommissioned, that portion will be evacuated, cleaned, isolated, and abandoned in place or removed per all State and local regulations and per the respective landowner agreements. 16. Who will provide fire protection to the site? Response: The Fort Lupton Fire District provides fire protection to this area. A referral packet will be sent to the District by the County. In advance of the USR submittal, Discovery has met with the district Fire Marshal who has reviewed the proposed pipeline route and emergency response plans. 1T 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. Response: The proposed natural gas gathering trunkline will incorporate two (2) remote pigging facilities located along the right-of-way within Weld County. There will be two (2) pigging facilities located along the right-of-way within Weld County. The first facility, also named the "West Brighton Pigging Facility", will be located approximately 2.700 ft. north of County Road 2 approximately half- way between County Roads 17 and 19 will incorporate the following: C.

This application is in accordance with Division 6, Section 23-2-440 of the County Code as discussed during the pre -application meeting held on January 13, 2017. This USR application is organized in an order to address the requirements of: i) the USR required submittal items outlined under Section 23-2-510 of the County Code, and ii) the additional information as outlined in the pre - application meetings and summary letters as requested by County staff. 1.1 OVERALL PROJECT OVERVIEW The Boardwalk Pipeline Project, approved on December 14, 2016 by the Weld County Board of County Commissioners (USR16-0028) incorporates a 29.4 -mile natural gas gathering trunkline originating at a Central Delivery Point ("CDP") Facility located in the SW of Section 24, Township 1S, Range 67W in Adams County, Colorado to Discovery's Ft. Lupton Gas Plant located approximately 4.3 -miles northwest of Lochbuie, Colorado in the SW of Section 11, Township 1N, Range 66W and approved on October 26, 2016 by the Weld County Board of County Commissioners (USR16-0031), where the gas is processed to recover natural gas liquids ("NGL")'s for delivery to a nearby third party via a 0.6 -mile NGL sales pipeline. Conversely, pipeline quality natural gas off the Ft. Lupton Gas Plant is delivered to a custody meter station for sales to a third -party transmission pipeline via a 1.4 -mile residue gas sales pipeline. Phase II of the Boardwalk Pipeline Project expands the original system west of the CDP facility with a new 20 - inch or smaller natural gas pipeline, 8 -inch crude oil pipeline, and 12 -inch or smaller water pipeline from a new pipeline pigging facility (Brighton West Interconnect Facility) located approximately 2,100 feet west from the intersection of E. 152nd Avenue and Holly Street on the north side of E-470 in Adams County and heading north approximately 4.5 miles before crossing into Weld County near the intersection of E. 168th Ave. / County Road 2 and Quebec Street. From the Adams County / Weld County line at E. 168th Ave. / County Road 2, the proposed 20 -inch or smaller natural gas pipeline, 8 -inch crude oil pipeline, and 12 -inch or smaller water pipelines will continue north into Weld County approximately 0.82 miles where they will terminate at a new pigging facility. From the pigging facility, the 20 -inch or smaller natural gas pipeline will continue north by north east approximately 9.47 miles to a second pigging facility located approximately 1,100 ft. north of the intersection of County Road 29 and County Road 6, before continuing in a general north by northeast direction approximately 4.95 miles to the Discovery Ft. Lupton Gas Plant. This Use by Special Review Permit application incorporates the portion of the Phase II Boardwalk Pipeline Project proposed 20 -inch natural gas pipeline from the Adams County / Weld County line near the intersection of E. 168th Ave. / County Road 2 and Quebec Street and following a north by northeast route approximately 15.2 miles via dual pigging facilities to the Discovery Ft. Lupton Gas Plant. Sections 1.1.1 through 1.1.4 below further describe the key infrastructure located within Weld County: 1.1.1 NATURAL GAS GATHERING TRUNKLINE The natural gas gathering trunkline will be constructed of 20.0" O.D. x 0.406" W.T., X-65, API 5L, PSL2, or comparable line pipe coated with 12-14 mils of fusion bond epoxy for external corrosion protection. All state highway, railroad, city and county road, and other crossings will be crossed by either bore or horizontal directional drill ("HDD"), thereby avoiding surface impacts in these areas, utilizing 20.0" O.D. x 0.500" W.T., X-65, API 51, PSL2 or comparable crossing pipe coated with 12-14 mils of fusion bond epoxy plus an additional 24-30 mils of abrasive resistant overlay coating. Although the natural gas gathering trunkline does not fall under the jurisdiction of the Code of Federal Regulations ("CFR"), the trunkline will be designed and constructed to meet the requirements of CFR Part 192 "Transportation of Natural and Other Gas by Pipeline". In general, under the CFR, Discovery is required to design and construct the trunkline for a Class 1 area classification utilizing a 0.72 design safety factor at a depth of 36 inches below ground level. As an additional recognized safety precaution, Discovery will design the pipeline for the more stringent Class 2 area classification utilizing a 0.60 design safety factor and all state highway, railroad, city and county road, and other crossing locations to a Class 3 area classification utilizing a 0.50 design safety factor. In addition, Discovery will bury the trunkline a minimum of 48 inches below grade. At all county and / or public roads crossings, the Prepared By: Se ZION ENGINEERING, LLC Page 5 of 27 Rear A, May 2017 BOARDWALK PIPELINE PROJECT 20 -INCH NATURAL GAS PIPELINE APPLICATION FOR USE BY SPECIAL REVIEW PERMIT DISCOVERY DJ SERVICES, LLC trunkline will be buried a minimum of 60 inches below the bottom of the bar ditches (USDOT and Weld County Public Works Department requires a minimum of 36 inches). Discovery will comply with all requirements for construction within unincorporated Weld County, the city of Ft. Lupton, the Colorado Department of Transportation, as well as the Nationwide Plan 12 permit for all waterway crossings, which allow waterways to be open cut or bored depending upon the condition of the waterway. The natural gas trunkline will be designed to facilitate routine pigging operations to remove liquids that drop out in the pipeline as well as in -line inspection of the line as required in accordance with the CFR. Table 1.2.1 below summarizes key information for the natural gas trunkline. Table 1.2.1 Boardwalk Pipeline Project — Phase II Weld County Line to Ft. Lupton Gas Plant Natural Gas Gathering Trunkline Pipeline Diameter 20.0" O.D. Pipeline Wall Thickness 0.406" W.T. (Line Pipe) f 0.500" W.T. (Crossing Pipe) Yield Strength 65,000 psi (X-65 Grade) Total Pipeline Length 19.5 miles Total Pipeline Length in Weld County 15.2 miles Total Parcel / Tract Count In Weld County 58 1.1.2 CRUDE OIL PIPELINE The crude oil pipeline will be constructed of 8.625" O.D. x 0.219" W.T., X-52, API 5L, PSL2 or comparable line pipe coated with 12-14 mils of fusion bond epoxy for external corrosion protection. All state highway, railroad, city and county road, and other crossings will be crossed either by bore or horizontal directional drill ("H DD" ), thereby avoiding surface impacts in these areas, utilizing 8.625" O.D. x 0.322" W.T., X-52, API 51, PSL2 or comparable crossing pipe coated with 12-14 mils of fusion bond epoxy plus an additional 24-30 mils of abrasive resistant overlay coating. Although the crude oil pipeline does not fall under the jurisdiction of the Code of Federal Regulations ("CFR"), the pipeline will be designed and constructed to meet the requirements of CFR Part 195 "Transportation of Hazardous Liquids by Pipeline". In general, under the CFR, Discovery is required to construct the pipeline at a depth of 36 inches below ground level. As an additional recognized safety precaution, Discovery will bury the pipeline a minimum of 48 inches below grade. At all county and / or public roads crossings, the pipeline will be buried a minimum of 60 inches below the bottom of the bar ditches (USDOT and Weld County Public Works Department requires a minimum of 36 inches). Discovery will comply with all requirements for construction within unincorporated Weld County as well as the Nationwide Plan 12 permit for all waterway crossings, which allow waterways to be open cut or bored depending upon the condition of the waterway. The crude oil pipeline will be designed to facilitate routine pigging operations as well as in -line inspection of the line as required in accordance with the CFR.

See Section 1.1.1 above. 3.2.2 DESCRIPTION OF THE PREFERRED ROUTE(S) & PROJECT ALTERNATIVES CONSIDERED A description of the preferred route or site and reasons for its selection. Discovery has evaluated numerous route options in the planning of the Project, with three viable route options considered as outlined in Figure 2.2.2 on the following page. Prepared By: Se ZION ENGINEERING, LLC Page 12 of 27 Rear A, May 2017 BOARDWALK PIPELINE PROJECT APPLICATION FOR USE BY SPECIAL REVIEW PERMIT 20 -INCH NATURAL GAS PIPELINE DISCOVERY DJ SERVICES, LLC Figure 2.2.2 — 20 -Inch or Smaller Natural Gas Trunkline Route Options The preferred route is shown in "Blue" above in Figure 2.2.2, while Alternative #1 and Alternative #2 are shown in "Magenta" and "Orange" respectively. While both alternatives offer a short, more direct route between the Brighton West Interconnect Facility, located in Adams County, and Discovery's existing Ft. Lupton Gas Plant located in Weld County; these alternatives are further from both existing and future planned well development and would thus yield longer interconnecting laterals from the respective well pads to facilitate delivery into the proposed trunkline, have a greater impact on nearby landowners and the general public in both Adams and Weld County, and have overall greater environmental impacts. Similar to the preferred route, construction activities for both Alternative #1 and Alternative #2 will have minimal, temporary and short term, effects on the residents, businesses and natural environment of Weld County. Table 2.2.2 below summarizes the respective route lengths and land affected by each alternative and the preferred route. Table 2.2.2 Project Alternatives Route Lengths & Land Affected, Weld County Acres of Land Affected Route (Based area of disturbance) on 80' wide Total Pipeline (miles) Length No. Road Crossings Alternative 1 127.0 acres 13.1 8 126.1 acres 13.0 8 147.8 acres 15.2 13 Preferred 3.2.2.1 ALTERNATIVE ROUTE #1 Alternative #1 routes north and west of the preferred route providing a total length of approximately 16.7 miles, with approximately 13.1 miles in Weld County. This Alternative would have the same originating point, located approximately 2,100 feet west from the intersection of E. 152nd Avenue and Holly Street on the north side of E-470 in Adams County, entering into Weld County approximately 125 ft. east of the intersection of E. 168th Ave / Prepared By: Page 13 of 27 Se ZION ENGINEERING, LLC Rear A, May 2017 BOARDWALK PIPELINE PROJECT 20 -INCH NATURAL GAS PIPELINE APPLICATION FOR USE BY SPECIAL REVIEW PERMIT DISCOVERY DJ SERVICES, LLC County Road 2 and Quebec Street. From the Weld County Line, this Alternative would travel north along Weld County Road 17 to a point approximately 2,600 ft. north of WCR 6 before turning east approximately 3 -miles to WCR 23 and then north to WCR 8 where the route would turn east, crossing the Platte River, U.S. Highway 85, and the BNSF railroad, before taking a general northeasterly alignment to Discovery's Ft. Lupton Gas Plant. This Alternative would incorporate an area of disturbance in Weld County approximately 13.1 miles long and 80 feet wide, or approximately 127.0 acres, with a permanent easement of 13.1 miles long and 50 feet wide, or approximately 79.4 acres. Route Maps for this Alternative are provided under Exhibit G.1 "Alternative Route #1 — Route Maps". 3.2.2.2 ALTERNATIVE ROUTE #2 Alternative #2 routes south and east of the preferred route providing a total length of approximately 16.5 miles, with approximately 13.0 miles in Weld County. This Alternative would have the same originating point, located approximately 2,100 feet west from the intersection of E. 152nd Avenue and Holly Street on the north side of E-470 in Adams County, entering into Weld County approximately 125 ft. east of the intersection of E. 168th Ave. I County Road 2 and Quebec Street. From the Weld County Line, this Alternative would travel east along E. 168th Ave. I County Road 2 approximately 3 -miles before turning north approximately 2 -miles, crossing WCR 23 and WCR 6 before turning east and crossing the Platte River, U.S. Highway 85, and the BNSF railroad and continuing in a general easterly direction to WCR 33 before turning north to Discovery's Ft. Lupton Gas Plant. This Alternative would incorporate an area of disturbance in Weld County approximately 13.0 miles long and 80 feet wide, or approximately 126.1 acres, with a permanent easement of 13.0 miles long and 50 feet wide, or approximately 78.9 acres. Route Maps for this Alternative are provided under Exhibit G.2 "Alternative Route #2 — Route Maps". 3.2.2.3 AIR QUALITY ALTERNATIVES The short-term emission sources impacting air quality would be the same for both Alternatives and the preferred route and would include construction equipment, typically diesel driven, and traffic on the roadways and right-of-way. Both Alternative #1 and Alternative #2 are in the same airshed as the preferred route. While both Alternatives are slightly shorter and incorporate less disturbed area than the preferred route, both Alternatives would require approximately the same construction duration. Construction for either Alternative or the preferred route is anticipated to occur in late 3rd Quarter 2017 based upon the anticipated receipt of the required permits. Water suppression will be utilized to reduce the amount of dust generated during construction, as necessary. 3.2.2.4 PREFERRED ROUTE The preferred route originates approximately 2,100 feet west from the intersection of E. 152nd Avenue and Holly Street on the north side of E-470 in Adams County, and travels in a general northeast direction, entering Weld County approximately 125 ft. east of the intersection of E. 168th Ave I County Road 2 and Quebec Street. From the Weld County Line, the route continues north following parcel boundaries approximately 0.89 miles to the proposed Brighton West Pigging Facility. From there, the route travels north through agricultural fields approximately 2.8 miles to County Road 8 before turning east approximately 0.9 miles and then traveling in a general southeasterly direction to County Road 6 and crossing the Platte River, U.S. Highway 85, and BNSF railroad and continuing in a general easterly direction to WCR 29, before taking a general northeasterly alignment to Discovery's Ft. Lupton Gas Plant. The preferred route would incorporate an area of disturbance of approximately 15.2 miles long and 80 feet wide, or approximately 417.8 acres, with a permanent easement 15.2 miles long and 30 feet wide, or approximately 92.1 acres. While this route is longer in distance than the Alternatives considered, the route bypasses the more populated areas of unincorporated Weld County, taking local landowner preferences into account and providing Prepared By: Se ZION ENGINEERING, LLC Page 14 of 27 Rear A, May 2017 BOARDWALK PIPELINE PROJECT 20 -INCH NATURAL GAS PIPELINE APPLICATION FOR USE BY SPECIAL REVIEW PERMIT DISCOVERY DJ SERVICES, LLC a mitigated impact to local businesses and residential areas. Route Maps for the preferred route are provided under Exhibit G.3 "Preferred Route - Route Mass". A list of the parcels along the preferred route within Weld County on which the pipelines will be located is provided under Exhibit H "Weld County Line List". 3.2.2.5 PREFERRED ROUTE CONSIDERATIONS & REASONING The preferred route was selected to mitigate the impacts to local businesses and residential neighborhoods; conform with the comprehensive plans for Adams County, Weld County, the cities of Thornton and Ft. Lupton; minimize impacts to the environment; and to the greatest degree possible, the preferences of local city and county landowners. The preferred route is located on lands within Weld County that are zoned as agricultural, Industrial, and PUD. In selection of the preferred route, Discovery considered the Weld County Comprehensive Plan along with the current and future development plans for the City of Ft. Lupton. In addition, in areas zoned for Agricultural, Discovery has worked with the applicable property owners to accommodate their considerations and preferences for the route and develop the preferred alignment to mitigate impacts to actively cultivated fields and productive areas. The preferred route does cross various canals associated with regional drainage and irrigation, including the German Ditch and Fulton Canal systems. Discovery will plan to cross these canals via bore or horizontal direction drill, in accordance with the respective canal company requirements. Permit applications for these crossings, and other crossings along the preferred route, including permits with CDOT for U.S. Highway 85 and BNSF for the railroad crossings. 3.2.3 MITIGATING MEASURES & TECHNIQUES Procedures to be employed in mitigating any adverse impacts of the proposed routes or sites. All pipelines will be buried to provide 48 -inches of cover. The pipeline trench will be excavated mechanically; pipe segments will then be strung along the ditch line and then welded together using welders and weld procedures qualified under the requirements of the Code of Federal Regulations; each weld will be examined utilizing industry standard non-destructive examination, or x-ray, procedures by qualified technicians; the coating on the pipeline will be inspected for damage and repaired as necessary and then the line(s) will be lowered into the trench and backfilled. The pipeline(s) will subsequently be pressure tested using water (hydrostatically tested) to industry regulations. All available topsoil will be conserved through a process known as "double -ditching", which excavates and removes and conserves topsoil where practical. Conserved topsoil will be windrowed separately from the underlying subsoil and stored along the construction right-of-way until the trench is backfilled, unless construction occurs during the winter with frozen soils. Under frozen soil conditions, topsoil salvage may be conserved using the following Best Management Practices ("BMP")'s: 1) topsoil would be ripped to a depth of 6 inches prior to stripping to allow for effective separation from the subsoil; and 2) topsoil would be sheared off from the subsoil layer to approximately 6 inches using appropriate equipment to accomplish topsoil salvage without mixing. Prior to construction, a Stormwater Management Plan ("SWMP") will be prepared to address stormwater and erosion control during construction activities. Stormwater Best Management Practices ("BMP")'s will be installed for the construction phase in accordance with the requirements of the SWMP. Erosion control BMP's will include, but not be limited to, silt fencing, straw wattles, hay bales, or combinations of these items, depending on the area requiring erosion control during construction. Construction staking will occur to designate the pipeline centerlines and outside construction right-of- way boundaries. The limits of disturbance will be clearly marked / staked prior to construction including the construction right-of-way, temporary use areas / work space, and access roads. Utility lines will be located and marked to prevent accidental damage during pipeline construction. Sensitive areas to be protected from disturbance or that require monitoring will be indicated on engineering documents and construction drawings and staked and marked accordingly in the field prior to construction. The location of access road entry points will be properly marked. Flagging, signs, and other markings Prepared By: Se ZION ENGINEERING, LLC Page 15 of 27 Rear A, May 2017 BOARDWALK PIPELINE PROJECT 20 -INCH NATURAL GAS PIPELINE APPLICATION FOR USE BY SPECIAL REVIEW PERMIT DISCOVERY DJ SERVICES, LLC identifying the limits of disturbance would be maintained through all phases of construction. A survey crew would be available during construction to replace any stakes that have been damaged or inadvertently removed. Wildlife and High Interest Species: Wildlife and high interest species surveys will be performed prior to construction and the applicable agencies consulted. This shall include: • •• • •:• • A Raptor nest survey will be completed if pipeline construction extends or is scheduled for the raptor nesting season (January 15 to July 31). If active raptor nests are found near the ROW (within 0.3 miles) the CDPW will be consulted to determine if any nest protection measures are needed. A nesting Burrowing Owl Survey will be completed if any black -tailed prairie dog towns are crossed during the period of owl activity (March 15 to October 31). If nesting burrowing owls are located consultations would occur with the CDPW to determine if any nest protection measures are needed. A Lite ladies' tresses orchid and Colorado butterfly plant survey would be completed in all wetlands that are proposed to be crossed by trenching. This survey would be completed during the plants blooming period (late July through August). If either species is located consultation would occur with the USFWS. The Colorado Parks and Wildlife District Wildlife Manager for the area will be consulted prior to construction. If there any issues of wildlife mortality (entrapment in the trench, or other mortality) the District Wildlife Manager will be notified. Archeology and Paleontology: On call archeologist and paleontologist would be available to consult if any potential archeological (stone tools, fire rings, foundations, bones) or paleontological (fossils) are found during construction/excavation of the trench and ROW. Project construction would be temporarily stopped until review by the archeologist/paleontologist. If needed the State Historic Preservation Office ("SHPO") would be consulted. Impacts to historic canal/ditch crossings would be avoided by completing these crossings by horizontal directional drill ("HDD"). Mobilization: Construction equipment will be transported to the construction right-of-way via tractor trailer and unloaded within designated staging area(s). Transportation equipment will be removed from the site or parked within a staging area once off-loading is completed. Clearing and Grading: Vegetation will be cleared and the construction right-of-way would be graded, to the degree necessary, to provide for safe and efficient operation of construction equipment and vehicles and to provide space for the storage of subsoil and topsoil. Construction activity and ground disturbance will be limited to approved, staked areas. Where required, trees will be cut with a chain saw and/or mechanical shears and brush would generally be cut with a hydro -axe or similar equipment. Trees and brush will be cut as close to the ground as possible. Vegetative material will typically be shredded and scattered back across the surface to increase roughness, facilitate seeding establishment, and protect the construction right-of-way. Stumps that are not shredded or chipped and that are incorporated into the topsoil will be removed and disposed of at an approved disposal facility. Vegetation may also be brush -hogged to preserve habitat. Topsoil will be stockpiled separately from subsoil and will not be used to pad the trench or construct trench breakers. In areas where the construction right-of-way crosses ephemeral drainages, the drainages will not be blocked with topsoil or subsoil piles. Topsoil and subsoil would be placed on the banks of the drainages. Gaps will be left periodically in the topsoil and subsoil piles to avoid ponding and excess diversion of natural runoff during storm events. Trenching: Trenching will be completed using track hoes or a mechanical trenching machine. The pipeline trench will be to one side of the construction right-of-way to allow for spoil to be placed opposite of the wider working side. It is not anticipated that blasting will be required during pipeline construction. Prepared By: Se ZION ENGINEERING, LLC Page 16 of 27 Rear A, May 2017 BOARDWALK PIPELINE PROJECT 20 -INCH NATURAL GAS PIPELINE APPLICATION FOR USE BY SPECIAL REVIEW PERMIT DISCOVERY DJ SERVICES, LLC Access will be provided for landowners and grazing rights holders to move vehicles, equipment, and livestock across the trench where necessary and consistent with prior agreement with landowners. Livestock operators will be contacted and adequate crossing facilities would be provided as needed to ensure livestock are not prevented from reaching water sources because of the open trench. The contractor will keep wildlife and livestock trails open and passable by adding soft plugs (areas where the trench is excavated and replaced with minimal compaction) during construction. Soft plugs with ramps on either side will be left at all well-defined livestock and wildlife trails and at no more than 0.5 -mile intervals along the open trench to allow passage across the trench and to provide a means of escape for livestock and wildlife that may fall into the trench. Trench breakers constructed of sand bags or polyurethane foam will be installed at specific spacing intervals to impede shallow groundwater from flowing down the trench. Lowering -in and Padding: Before the pipe section is lowered into the trench, an inspection will be conducted to verify that the pipe is properly fitted and installed in the trench, minimum cover is provided, and the trench bottom is free of rocks and other debris that could damage the external pipe coating. The pipe sections will be simultaneously lifted in position over the trench and lowered in place. Sifted soil fines from the excavated subsoil will provide rock -free pipeline padding and bedding. Sandbags may be used to pad the bottom of the trench instead of, or in combination with, padding with soil fines. In rocky areas, padding material or a rock shield will be used to protect the pipe and coating. Topsoil will not be used to pad the pipe. Backfilling Pipeline: Shading and backfill will begin after a section of pipe has been successfully placed in the trench, inspected, and approved for backfill. Backfill will be conducted using a bulldozer or other suitable equipment. Subsoil excavated from the trench will generally be used to backfill the trench, except in rocky areas where imported select fill material may be needed. Backfill will be graded and compacted, where necessary, for ground stability, by tamping or walking with a wheeled or tracked vehicle. Compaction will be conducted to the extent that there would be no voids in the trench. Any excavated materials or materials unfit for backfill will either be utilized elsewhere or properly disposed of in accordance with applicable laws, regulations and landowner agreements. Cleanup and Restoration: Cleanup and restoration will occur after the pipeline is installed and backfill is completed, or in the spring following construction if weather conditions would inhibit the proper restoration activities, to minimize the length of time that the open trench and un-stabilized right-of-way is present. Cleanup of the surface along the construction right-of-way will include removal of construction debris and final grading to the finished contours. Permanent erosion control measures will be installed as required and seeding would occur in accordance with landowner requirements. Invasive and noxious weeds will be controlled after construction until the right-of-way is restored. Road Crossings: All county road crossings will be completed by conventional bore or directional drill methodology with sufficient depth to maintain a minimum of 60 -inches of cover at the lowest bar ditch. Waterbody Crossings: All streams and named ditch / canal crossings will be completed via HDD to avoid disturbance of the stream and ditch bed and banks. Each HDD will begin, end and be of sufficient depth to ensure the pipeline is not subject to the hazard of stream scour during anticipated flood events. If the HDD crossing avoids impact to all associated wetlands, a U.S. Army Corps of Engineers (USACE) 404 permit will not be necessary for this crossing. In areas with trenched wetland crossings, the construction right-of-way will be reduced from 80 feet in width to 50 feet in width, where only the ditch line will be topsoiled and the drive space will be matted with pipeline mats to mitigate disturbance. Blading would occur only over the trench line and the construction traffic / access area would be matted to avoid vegetation disturbance. If standard open cut construction methods are used in wetland areas, Discovery will obtain the necessary ACOE 404 perm its. 3.2.4 PROJECT DESIGN, PERMITTING, CONSTRUCTION & COMMISSIONING SCHEDULE An outline of the planned construction, including startup and commissioning schedule, to include the number of stages and timing of each.

Prepared By: Se ZION ENGINEERING, LLC Page 18 of 27 Rear A, May 2017 BOARDWALK PIPELINE PROJECT 20 -INCH NATURAL GAS PIPELINE APPLICATION FOR USE BY SPECIAL REVIEW PERMIT DISCOVERY DJ SERVICES, LLC The transportation of natural gas and other hazardous materials via pipeline is generally safer than other potential modes of transport. There is some small risk of an accident in which the integrity of the pipeline may be compromised resulting in a release of natural gas or natural gas liquids. Wet natural gas contains condensed forms of heavier natural gas liquids and produced water and is considered both flammable and combustible. Dry natural gas is a clean burning fuel source, also considered both flammable and combustible. In general, signs of a pipeline leak, include dead or discolored vegetation that is otherwise green along the pipeline right-of-way, along with pools of liquid or clouds of vapor or mist not usually present. Discovery will clearly mark the pipeline centerline with markers placed at line of site intervals and at all road, railroad and canal crossings. The markers will clearly identify the pipeline, and will provide a telephone number and address where a company representative can be reached in an emergency or prior to any► excavation in the area. Discovery will also participate in the Colorado "One Call" system, which serves as a clearinghouse for excavation activities that are planned close to pipelines and other underground utilities. Discovery employs highly trained operators and contractors and maintains close working relationship with all emergency response personnel. 3.2.7 DESCRIPTION OF EMERGENCY PROCEDURES A description of emergency procedures to be followed in case of a reported failure or accident involving the proposed PIPELINE. Such outline shall include actions, if any, required of PUBLIC officials, including fire and police officials, and the names and telephone numbers of appropriate company officials to notify if an accident or failure should occur. Each respective pipeline centerline will be clearly identified with markers placed at line of sight intervals and at all road, railroad and canal crossings. These markers will clearly identify Discovery as the owner / operator, provide a telephone number and address where a company representative can be reached in an emergency. In the event of an emergency, a call to the number on these markers will go to Discovery's operations and control center located at the gas compression and processing facility. This facility will be staffed 24 hours / day, 7 days / week, 365 days / year by trained operators, qualified in both the day-to-day operation of the respective pipelines and associated facilities, but in emergency response procedures. These operators will also have the ability to monitor the operation of the pipeline system through a Supervisory Control and Data Acquisition ("SCADA") system. Through the SCADS► system, operators will be able to see key parameters associated with the operation of the respective pipelines, including pressure, temperature, and flow rate. In the event that these parameters, or other critically identified criteria fall outside of pre -determined normal operating allowances, the SCADA system will raise warnings of potential operational upsets or pending emergency conditions, providing the operator with time to make corrections, if possible, to the system operation in order to clear the warning. In the event that the specified parameters, or critically identified criteria reach pre -determined setpoints within the system operation, the SCADA system will alarm. Upon notification of an emergency, either through the public emergency call number, SCADA system, operator inspection and training, or other originating source, Discovery will have the ability to isolate the respective pipelines by closing remotely operated valves at either end of the pipeline or, on the natural gas gathering trunkline, at the three (3) remote pigging facility valves located along the line to isolate any potential fuel source and mitigate propagation of the emergency situation. In addition, Discovery operations personnel will have the ability to locally evacuate the natural gas pipeline via blowdowns located at each end of the line and at each respective remote pigging facility site. Depending upon the nature of the emergency, local emergency responders would be notified, and Discovery would implement their internal safety response procedures, including dispatching trained personnel to the site of the emergency. The specified emergency contact number for Discovery's Ft. Lupton Gas Plant has not yet been determined, but will be provided to the County and appropriate local emergency responders prior to commissioning of the Phase I pipeline system, and confirmed prior to commissioning of the Phase II pipeline system under this USR application. In the mean -time, emergency notifications or inquiries Prepared By: Se ZION ENGINEERING, LLC Page 19 of 27 Rear A, May 2017 BOARDWALK PIPELINE PROJECT 20 -INCH NATURAL GAS PIPELINE APPLICATION FOR USE BY SPECIAL REVIEW PERMIT DISCOVERY DJ SERVICES, LLC during construction of the project can be directed to Discovery's Project Manager, or on -site Construction Manager as provided below: 3.2.7.1 PROJECT MANAGER Cory Jordan Discovery DJ Services, LLC 7859 Walnut Hill Lane, Suite 335 Dallas, TX 75230 (318) 272-1018 3.2.7.2 CONSTRUCTION MANAGER Jeff Brewster Quality Check Energy Services, LLC 562 north 7th avenue Brighton, CO 80601 (318) 348-7693 3.2.8 MITIGATING MEASURES TO IMPACTS ON IRRIGATED AGRICULTURAL LANDS A description of the method or procedures to be employed to avoid or minimize the impacts on irrigated agricultural land. Discovery has worked with each respective landowner to develop the preferred alignment to mitigate impacts to irrigated and I or actively cultivated fields and productive areas. The impacts to these lands will in addition be further mitigated by: ❖ Minimizing the construction right-of-way and associated surface disturbance to the degree possible; ••• Routing the pipeline so -as to avoid affecting the operation of irrigation equipment; +:• Segregating topsoil from excavated spoils to facilitate subsequent restoration following construction; + Following construction of the pipeline, the ROW will be seeded or left fallow in accordance with the agreed individual landowner reclamation procedures. 3.2.9 CONFORMANCE TO WELD COUNTY CODE, CHAPTER 22 OF THE COMPREHENSIVE PLAN A discussion of how the proposal conforms with the guidelines of Chapter 22 of this Code and any other applicable code provision or ordinance in effect. Section 22-2-10(D) of the Weld County Code states that "extraction of natural resources is an important part of the economy of the County." These proposed pipelines will contribute to the expansion of the County's industrial economic base by providing increased capacity for future marketing of natural gas and crude oil production in Weld County. Additionally, Section 22-5-100 (A) states that a County goal is to "promote the reasonable and orderly exploration and development of oil and gas mineral resources." Per Chapter 22 of the Code, oil and gas facilities are allowed as a use by right in the A (Agricultural) zone district, in which the majority of the properties along the proposed pipeline routes are zoned. In addition, Weld County Code Section 23-2-200 et seq. permits construction of oil and gas support and service facilities in agricultural zoned districts. Section 22-5- 90 of the Weld County Code Comprehensive Plan states: "The most efficient and environmentally friendly way to transport crude oil is by pipeline, rather than by truck. Transportation of the product by pipeline has less impact on County roads. Less truck traffic also benefits air quality in the area". Weld County Code Section 22-5-100 further states: "Oil and gas activities should be planned to accommodate current and future subdivision activities to the extent such development can reasonably be anticipated". Prepared By: Se ZION ENGINEERING, LLC Page 20 of 27 Rear A, May 2017 BOARDWALK PIPELINE PROJECT 20 -INCH NATURAL GAS PIPELINE APPLICATION FOR USE BY SPECIAL REVIEW PERMIT DISCOVERY DJ SERVICES, LLC The proposed pipelines meet the objectives outline in the Weld County Code Comprehensive Plan without rezoning or changing the use of the land. The pipelines will be buried beneath the ground's surface and therefore the effect on any active agriculture will be temporary and isolated to the construction phase of the project. Following construction, the surface along the pipeline right-of-way will be restored to its prior condition, and agricultural activities may resume. 3.2.10 DECOMMISSIONING PLAN A Decommissioning Plan. During operation of the pipelines, should it become necessary to decommission a portion of a line for maintenance or repair activities, pressure on the pipeline would be reduced to a safe operating pressure, or completely blown down utilizing blowdown valves at the respective remote pigging facility sites or either end of the pipeline. Liquids on the crude oil pipeline would be displaced utilizing a pipeline pig propelled with dry air, nitrogen, water or other approved inert material. All decommissioning activities would be performed using written procedures designed for the specific requirements and situation. As part of the decommissioning plan, all local emergency responders would be notified in advance and affected landowners notified, as necessary. There is no intention of ceasing operations of the respective pipelines once they are operational. However, in the event that any portion of the pipeline system is permanently decommissioned, that portion will be evacuated, cleaned, isolated, and abandoned in place or removed per all State and local regulations and per the respective landowner agreements. 3.2.11 DESCRIPTION OF HAUL ROUTES A description of any haul routes during construction, identifying the roads and bridges involved and the weight of the loads. Staging for construction in Weld County will be performed from Discovery's Ft. Lupton Gas Plant (USR16-0031). It is anticipated that the construction contractor will mobilize their equipment to the staging area utilizing U.S. Highway 85 or Colorado Interstate 76 followed by County Road 12 1�2 1 Highway 52 and then south on WCR 35 to the temporary staging area. Construction equipment will be transported utilizing semi -tractor and flatbed trailers, or comparable equipment, with gross vehicle weights estimated at 40,000 — 80,000 lbs. Pipe for the construction of the respective pipelines will be strung directly to the right-of-way from the applicable pipe supplier. The main haul routes will incorporate Highway 85, Colorado Interstate 76, WCR 2 / E. 168th Ave., WCR 6, WCR 19 and WCR 23. From the respective state and county roads, stringing trucks will access the pipeline right-of-way utilizing temporary access drives at the respective pipeline crossing locations outlined under Table 1.2.1a above, and off WCR 6. The estimated maximum gross vehicle weight for a loaded stringing truck with 20 -Inch pipe will be between 71,000 — 77,000 lbs. In addition, construction personnel utilizing 1 -ton pick-up trucks and comparable sized vehicles will access the right-of-way utilizing similar ingress / egress routes. The expected haul routes include both Colorado Department of Transportation ("CDOT") highways and Weld County roads. Upon review of the Weld County Restricted Bridge Locations Map, dated October 2016, it was determined that the project area does not incorporate any restricted bridges. Similarly, the current state of CDOT roads and bridges for the proposed haul routes were reviewed utilizing the Colorado Department of Transportation's Online Transportation Information System, Highway Data Explorer. The findings of this review are outlined below and on the following pages. 3.2.11.1 US Highway 52: The main routes were selected starting with US Highway 52 / WCR 12 1/2 as shown in Figure 2.2.11.1 on the following page.

EXHIBIT USE BY SPECIAL REVIEW QUESTIONNAIRE SITE SPECIFIC DEVELOPMENT PLAN AND USE BY SPECIAL REVIEW (USR) QUESTIONNAIRE The following questions are to be answered and submitted as part of the USR application. If a question does not pertain to your use, please respond with "not applicable", with an explanation as to why the question is not applicable. Planning Questions 1. Explain, in detail, the proposed use of the property. Response: The Project will incorporate three (3) pipelines that will require easements within Weld County: 1) A 20 -inch, or smaller, natural gas gathering trunkline. The natural gas trunkline will originate at Discovery's new Brighton West Interconnect pigging facility located in the SWSE of Section 7, Township 15, Range 67W, approximately 2,100 feet west from the intersection of E. 152nd Avenue and Holly Street on the north side of E-470 in Adams County, Colorado and will transport wet natural gas via a new 19.5 mile trunkline north to Discovery's Ft. Lupton Gas Plant (USR2016-0031) located approximately 4.3 miles northwest of the town of Lockbuie, Colorado in the SW of Section 11, Township 1N, Range 66W. The trunkline will enter Weld County via a bored crossing of E. 168th Ave.! County Road 2 in Section 33, Township 1N, Range 67W near the intersection of E. 168th Ave. I County Road 2 and Quebec Street. From the Weld County Line, the trunkline continues north following parcel boundaries approximately 0.89 miles to Discovery's proposed Brighton West Pigging Facility incorporated under this USR application. From there, the route travels north through agricultural fields approximately 2.8 miles to County Road 8 before turning east approximately 0.9 miles and then traveling in a general southeasterly direction to County Road 6 and crossing the Platte River, U.S. Highway 85, and BNSF railroad and continuing in a general easterly direction to WCR 29, before taking a general northeasterly alignment to Discovery's Ft. Lupton Gas Plant. The 20 -inch, or smaller, natural gas gathering trunkline will be constructed within the following Township, Range and Sections: 33-67-01, 28-67-01, 27-67-01, 22-67-01, 15-67-01, 14-67-01, 23- 67-01, 24-67-01, 19-66-01, 20-66-01, 21-66-01, 22-66-01, 15-66-01, 14-66-01, 11-66-01 and will incorporate the acquisition of a 50 ft. permanent easement plus 30 ft. temporary construction easement providing for a total 80 ft. construction right-of-way. 2) An 8 -inch crude oil pipeline. The crude oil pipeline will originate at the proposed Brighton West Pigging Facility located in the SENW of Section 33, Township 1N, Range 67W and will transport produced crude oil via a new 5.19 mile pipeline south to Discovery's proposed Brighton West Interconnect located in the SWSE of Section 7, Township 1S, Range 67W, approximately 2,100 feet west from the intersection of E. 152nd Avenue and Holly Street on the north side of E-470 in Adams County, Colorado where it will be delivered into Discovery's crude oil pipeline system and transported north to Platteville, Colorado for subsequent sales to regional markets. The 8 -inch crude oil pipeline will be constructed within the following Township, Range and Sections: 33-67-01 and will be placed within the same 50 ft. permanent easement as the 20 -inch, or smaller, natural gas gathering trunkline. 3) A 12 -inch, or smaller, produced water pipeline. The produced water pipeline will originate at the Ward Petroleum's Ivey West well pad located in the SE of Section 11, Township 1S, Range 68W approximately 1,600 ft. southwest of the intersection of E. 152nd Ave. and the eastbound E-470 ramp and travel in a general easterly direction along the E-470 multi -use corridor to Discovery's new Brighton West Interconnect pigging facility located in the SWSE of Section 7, Township 1S, Range 67W, approximately 2,100 feet west from the intersection of E. 152nd Avenue and Holly Street on the north side of E-470 in Adams County, Colorado before continuing north, entering into Weld County near the intersection of E. 168th Ave. / County Road 2 and Quebec Street and continuing approximately 0.89 miles to the proposed Brighton West Pigging Facility located in the SENW of Section 33, Township 1N, Range 67W where the line will be capped for future use. The 12 -inch, or smaller, produced water pipeline will be constructed within the following Township, Range and Sections: 33-67-01 and will be placed within the same 50 ft. permanent easement as the 20 -inch, or smaller, natural gas gathering trunkline and 8 -inch crude oil pipeline. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. Response: Section 22-2-10(D) of the Weld County Code states that "extraction of natural resources is an important part of the economy of the County." These proposed pipelines will contribute to the expansion of the County's industrial economic base by providing increased capacity for future marketing of natural gas and crude oil production in Weld County. Additionally, Section 22-5-100 (A) states that a County goal is to "promote the reasonable and orderly exploration and development of oil and gas mineral resources." Per Chapter 22 of the Code, oil and gas facilities are allowed as a use by right in the A (Agricultural) zone district, in which the majority of the properties along the proposed pipeline routes are zoned. In addition, Weld County Code Section 23-2-200 et seq. permits construction of oil and gas support and service facilities in agricultural zoned districts. Section 22-5-90 of the Weld County Code Comprehensive Plan states: "The most efficient and environmentally friendly way to transport crude oil is by pipeline, rather than by truck. Transportation of the product by pipeline has less impact on County roads. Less truck traffic also benefits air quality in the area". Weld County Code Section 22-5-100 further states: "Oil and gas activities should be planned to accommodate current and future subdivision activities to the extent such development can reasonably be anticipated". The proposed pipelines meet the objectives outline in the Weld County Code Comprehensive Plan without rezoning or changing the use of the land. The pipelines will be buried beneath the ground's surface and therefore the effect on any active agriculture will be temporary and isolated to the construction phase of the project. Following construction, the surface along the pipeline right-of-way will be restored to its prior condition, and agricultural activities may resume. However, oil and gas pipelines require a Use by Special Review (USR) permit in Weld County. 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. Response: Weld County Code Section 23-3-20 identifies that oil and gas production infrastructure is allowed as a use by right in agricultural zone districts. The pipelines are located primarily within the agricultural zone district, and such zoning allow oil and gas support and service infrastructure such as pipelines. Any impacts to actively cultivated land by the project will be temporary, and agricultural operations can resume once the pipelines are operational. Section 23-3-40 also indicated that Oil and Gas Support and Service Facilities are acceptable as a Use by Special Review in the district. 4. Describe what type of land uses surround the site. Explain how the proposed use is consistent and compatible with surrounding land uses. Response: The respective pipeline routes are primarily located in unincorporated Weld County in the agricultural zone district. The area surrounding the pipelines primarily consist of plowed fields, pivot irrigation system, County Estates and industrial complexes. The project is consistent and compatible with the surrounding land uses as a use allowed by right under Weld County Code Section 23-3-20. 5. What are the hours and days of operation? (e.g. Monday thru Friday 8:00 a.m. to 5:00 p.m.) Response: The hours of operation for the respective pipelines will be 24 hours per day, 7 days per week, 365 days per year. 6. List the number of full time and/or part time employees proposed to work at this site. Response: The operation and maintenance of the pipelines will be performed by trained and qualified operators and pipeline technicians stationed at Discovery's Ft. Lupton Gas Plant (USR16- 0031). There will be approximately 7-10 full-time employees working out of gas plant, with two shifts per day anticipated. The day shift will have approximately 6-8 full time employees, followed by a night shift with a single operator on duty. Shift hours have yet to be confirmed, but a typical shift rotation may be 6 a.m. to 6 p.m. 7 If shift work is proposed include the number of employees per shift. Response: See Response to Planning Question No. 6 above. 8. List the number of people who will use this site. Include contractors, truck drivers, customers, volunteers, etc. Response: During construction, approximately 50-75 construction personnel, including the construction contractor and Discovery's construction management team, will be required to construct the pipeline along the right-of-way. Following construction, the respective pipelines will be operated and maintained by approximately 6-12 people per day, including full time employees, contractors and third party truck drivers. 9. If this is a dairy, livestock confinement operation, kennel, etc., list the number and type of animals. Res aonse: There will be no animals on site. 10. Describe the type of lot surface and the square footage of each type. (e.g. asphalt, gravel, landscaping, dirt, grass, buildings) Response: Not Applicable. 11. How many parking spaces are proposed? How many handicapped (ADA) parking spaces are proposed? Response: Not Applicable. 12. Explain the existing and proposed landscaping for the site. Response: Following construction, the right-of-way and all disturbed areas will be restored to their pre -construction conditions and contours. Agricultural land will return to agricultural uses, native grassland habitats would be reseeded. Similarly, all wetland areas will be restored to pre - construction conditions and contours, topsoil will be replaced and the wetland will be reseeded. Wetlands should return to preconstruction conditions within 1-2 growing seasons. Permanent erosion control measures will be installed as required and seeding would occur in accordance with landowner requirements. Invasive and noxious weeds will be controlled after construction to minimize further propagation pursuant to Chapter 15, Articles I and II of the Weld County Code, until the right-of-way is restored. No additional landscaping is proposed. 13. Describe the type of fence proposed for the site (e.g. 6 foot chain link with earth tone slats) Response: Only fencing around the two (2) respective pigging facilities will be required. These locations will be enclosed with a 6 -foot tall chain link fence plus 2 -foot outrigger and 3 -strands of barbed wire and will incorporate a 20 -foot drive gate for access. 14. Describe the proposed screening for all parking and outdoor storage areas. If the site is located in a floodplain outdoor storage is restricted. Response: No permanent parking or storage areas will be required. 15. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. Response: During operation of the pipeline, should it become necessary to decommission a portion of the line for maintenance or repair activities, pressure on the pipeline would be reduced to a safe operating pressure, or completely blowndown utilizing blowdown valves at the respective pigging facility sites or either end of the pipeline. Liquids on the crude oil and r or produced water pipelines would be displaced utilizing a pipeline pig propelled with dry air, nitrogen, water or other approved inert material. All decommissioning activities would be performed using written procedures designed for the specific requirements and situation. As part of the decommissioning plan, all local emergency responders would be notified in advance and affected landowners notified, as necessary. There is no intention of ceasing operations of the respective pipelines once they are operational. However, in the event that any portion of the pipeline system is permanently decommissioned, that portion will be evacuated, cleaned, isolated, and abandoned in place or removed per all State and local regulations and per the respective landowner agreements. 16. Who will provide fire protection to the site? Response: The Fort Lupton Fire District provides fire protection to this area. A referral packet will be sent to the District by the County. In advance of the USR submittal, Discovery has met with the district Fire Marshal who has reviewed the proposed pipeline route and emergency response plans. 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. Response: The proposed natural gas gathering trunkline will incorporate two (2) remote pigging facilities located along the right-of-way within Weld County. There will be two (2) pigging facilities located along the right-of-way within Weld County. The first facility, also named the "West Brighton Pigging Facility, will be located approximately 2.700 ft. north of County Road 2 approximately half- way between County Roads 17 and 19 will incorporate the following: +.+ One (1) 20 -Inch or Smaller, ANSI 600 Natural Gas Pig Receiver; +*+ One (1 ) 20 -Inch or Smaller, ANSI 600 Natural Gas Pig Launcher; + One (1) 8 -Inch, ANSI 600 Crude Oil Pig Launcher; The second pigging facility, also named the "Ft. Lupton Pigging Facility", will be located approximately 1,100 ft. north of the intersection of County Roads 6 and 29 on the east side of County Road 29 and will incorporate the following: C. One (1) 20 -Inch or Smaller, ANSI 600 Natural Gas Pig Receiver; + One (1) 20 -Inch or Smaller, ANSI 600 Natural Gas Pig Launcher; Overall, the respective pigging facility sites will be approximately 60 ft. wide x 125 ft. long, or approximately 0.17 -acres each and will be enclosed with a 6 -foot tall chain link fence plus 2 -foot outrigger and 3 -strands of barbed wire. Construction of these pigging facilities will occur concurrently with pipeline construction and is anticipated to take approximately 3-4 months to complete. Engineering Questions 1. Describe how many roundtripslday are expected for each vehicle type: Passenger Cars/Pickups, Tandem Trucks, Semi-Truck/Trailer/RV (Roundtrip = 1 trip in and 1 trip out of site) Response: During construction, stringing trucks will be used to haul and string pipe along the length of the right-of-way. Stringing activities are anticipated to take approximately 3-4 weeks and would start following clearing and grading of the right-of-way and once ditching activities have progressed far enough along the length of the right-of-way to avoid conflicts. In addition, welding trucks and 1 - ton pick-up trucks will be required along the right-of-way for welding activities and construction management personnel. Following construction, during normal operations, vehicles will not be required along the right-of-way. Operations personnel will periodically drive the adjacent county roads along the right-of-way for visual inspection of the easement and to perform routine maintenance activities (approximately 2-3 round trips per month). 2. Describe the expected travel routes for site traffic. Response: The primary travel routes will be along U.S. Highway 85, Interstate 1-76, and U.S. Highway 52 along with County Roads 4, 6, 8, 10, 19, and 23. 3. Describe the travel distribution along the routes (e.g. 50% of traffic will come from the north, 20% from the south, 30% from the east, etc.) Response: During construction, the primary source of travel will be from the north out of Discovery's Ft. Lupton Gas Plant (appx. 75%) with the balance (appx. 25%) from the east. Following construction travel distribution will almost entirely come from the north out of the Ft. Lupton Gas Plant. 4. Describe the time of day that you expect the highest traffic volumes from above. Response: The greatest volume of traffic will occur between 7 a.m. — 5 p.m., Monday through Saturday. Describe where the access to the site is planned. Response: Temporary access to the pipeline right-of-way will occur at the various County Road crossings as outlined under Table 1.2.1a under the USR. Application and at existing access drives along the route of the pipelines. Following construction, required access to the right-of-way will be limited to foot traffic for periodic maintenance and inspection activities and via existing access drives along the alignment. 6.

Concerns / Issues & Responses 1. Question (Mr. Randy): How do you access the Right of Way? Response: We will access the right-of-way from existing roadways where possible and secure temporary access permits where needed. We do everything we can to stay in our Right of Way throughout construction. 2. Question (Mr. Randy): Will there be any problems with building a shed next to the Right of Way? Response: No, there are no problems. 3. Question (Mr. Randy) - Is this the final routing of the pipeline? Response: This is our preferred routing but it is not finalized. We have explored numerouse me rouse alternative routes, and are still working through discussions with landowners. /E.,zIINon I 4. Question (Mr. AJ Goddard): If local regulations change, will Discovery compensate me for any change of value to my property? Response: That would have to be discussed at that time. 5. Question (Mr. AJ Goddard): How big is the easement? Response: There is a 50 ft. permanent easement, 30 ft. temporary easement. 6. Question (Mr. AJ Goddard): How big is the pipeline? Response: It is a 20" pipeline, 7. Question (Mr. AJ Goddard): How deep is the pipeline? Response: The pipeline will be buried a minimum of 48" deep. 8. Question (Mr. AJ Goddard): What does this pipeline do to property values? Response: It should not change your property value. 9. Question (Mr. AJ Goddard): Why not go through Todd Creek? Response: We've looked at various route options, but have selected the preferred route based upon input from landowners and in an effort to minimize impacts to local neighborhoods and businesses. 10. Question (Mr. AJ Goddard): What sections of the pipeline are above grade? Response: At this time, we anticipate having a couple of above grade pigging facilities. Their actual location has not yet been determined. 11. Question (Mr. AJ Goddard): Where is the construction information posted such as a list of contractors etc.? Response: We have not yet selected the contractors for the project, but don't plan to post the contractor list publically. 12. Question (Mr. AJ Goddard): Where is this pipeline going? Response: This pipeline is going to the Ft. Lupton gas plant. 13. Question (Mr. Larry): What kind of response can we expect if there is trouble? Response: Someone will likely be out in 30 minutes. 14. Question (Mr. Larry): Do you monitor the pipeline? ZION ENGINEERING Response: Yes, the pipeline right-of-way will be flown via aircraft once a month to inspect for encroachment on the right-of-way or potential damage to the pipeline. 15.

Question (Mr. Larry): How long do you expect you will be constructing on my property? Response: For normal pipeline/ theprocess will be an assembly line. The first crew will come through and clear/segregate the top soil. Then the second crew will come through and lay out all of the pipe. After that the weld crew will come through and weld the pipe together. Then the pipe will be placed in the ground. The final crew will restore the Right of Way by seeding. The amount of time on your property will be a case by case basis depending on the length, but will roughly last about a month. 20. Question (Mr. Larry): What oversight will be in place for pipeline protection and leak avoidance/response? Response: All the pipeline will be built to federal code using a thicker steel than is required. The pipe will also be buried deeper than required. All pipe will be coated and cathodically protected. All pipe will be pressure tested with water to a pressure higher than the operating pressures. Fluid will be metered going into and out of the pipe. All welds will be x-rayed. 21.

The pipeline begins at the Adams/Weld County line 4 miles southwest of Wattenberg, Colorado, and runs generally northeast to located location 3.5 miles southeast of Fort Lupton, Colorado (Figure 1, project overview map, in Appendix A) . SWCA Environmental Consultants (SWCA) completed a field and geographic information systems (GIS)/literature review of the pipeline route to determine if the project area supports important plant communities, wetlands, and wildlife habitat; potential habitat for special status species; or known cultural resource sites. 2.1 Site Description, Vegetation, Wildlife SWCA completed field surveys on the entire proposed pipeline in February, March and May 2017. The field review was designed to identify potential ecological and environmental issues that may need to be addressed as the project is developed. 1 2.2 General Land Use and Plant Communities The project is primarily within a mixture of irrigated and dryland agricultural lands. The common agricultural lands include dryland wheat, corn, alfalfa, and grass hay. The project also crosses herbaceous native upland habitat dominated by non -woody vegetation (i.e., grasses and forbs). The dominant species are blue grama (Bouteloua gra cilis), buffalograss (Bouteloua dactyloides), western wheatgrass (Pascopyron srnithii), and slender wheatgrass (Elymus trachycaulus). These grassland communities are in generally poor condition due to disturbance and therefore have become infested with invasive species that include cheatgrass (Bromus tectorum), musk thistle (Carduus nutans), and Canada thistle (Cirsium canadensis). Multiple wetlands are also crossed by the project, dominated by hydrophytic species such as narrowleaf cattails (Typha angustifolia), Nebraska sedge (Carex nabrascensis), Baltic rush (Juncus balticus), and saltgrass (Distichlis spicata). The vegetation types crossed by the proposed project are summarized in Table 1. Table 1. Land Cover Types Crossed by the Project in Weld County Land Cover Type Miles Crossed (feet) Acres Impacted Construction PE, IWS, (Full by ATWS) Project ROW — Agricultural/tilled, including pasture and hay 13.77 (50,488) 121.04 Grassland 1.1 (5,808) 9.78 Developed residential, (industrial, etc.) 0.17 (897) 1.55 Wetland 0.09 (475) 0.83 Total 15.08 (79,622) 133.2 The presence of plant species listed on the Colorado Department of Agriculture's noxious weed list (2015) « as identified during field surveys. A complete inventory of weed occurrences allows for proper planning to control the spread of weeds in the project area. In the case that a noxious weed occurrence was identified in the field, the occurrence location or boundary was recorded with a global positioning system (GPS) unit, field notes were recorded, and photographs were collected to document this location. Six noxious weed occurrences are located within the survey corridor. The noxious weed populations that were observed along the surveyed portion of the route are summarized in Table 2, and their locations are illustrated in Figure 2 in Appendix A. Table 2.

The presence/absence of wetlands was evaluated in the field using routine delineation methods described in the U.S. Army Corps of Engineers Wetlands Delineation Manual (U.S. Army Corps of Engineers [USAGE] 1987), and in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Great Plains Region (version 2.0) (USACE 2010), hereinafter referred to as the Regional Supplement. Wetlands are characterized by a predominance of hydrophytic vegetation, presence of hydric soils, and presence of wetland hydrology. While surveying the proposed alignment, field investigators scanned the survey corridor for visual evidence of changes in vegetation composition consistent with prolonged inundation or saturation, and changes in surface features indicating the presence of wetland hydrology. If any of these circumstances were present, field investigators collected data necessary to complete a Regional Supplement Wetland Determination Data Form, providing documentation of the presence or absence of wetlands. Determination of wetland habitat type, if present, was based on the classification system developed by Cowardin et al. (1979). Wetland boundaries, if observed, were recorded at the upland/wetland interface on the GPS unit. The presence/absence of lotic systems (e.g., creeks, rivers, arroyos, human -made ditches; collectively "streams") was identified in the field pursuant to guidance provided in the USACE Regulatory Guidance Letter No. 05-05 regarding ordinary high water mark (OHWM) identification (USAGE 2005). An OHWM is a line on a shore established by fluctuations of water and indicated by physical characteristics such as a clear, natural line impressed on the bank; shelving; changes in the character of the soil; destruction of terrestrial vegetation; the presence of litter and debris; or other appropriate means that consider the characteristics of the surrounding areas. The OHWM is the defining element for identifying the lateral limits of non -wetland waters. Federal jurisdiction over a non -wetland water of the U.S. typically extends to the OHWM. All waterbodies were recorded on a Trimble GPS unit and photographs were taken at each site. The locations of wetland, stream, and canal crossings are illustrated in Figure 2 in Appendix A. The pipeline right-of-way (ROW) crosses 4 wetlands, 3 streams/rivers, and 14 canals/ditches, as summarized in Table 3. Table 3. Stream, Ditch, and Wetland Crossings in.

HDD = horizontal directional drilling OO = open cut The route crosses wooded riparian habitat in and around the South Platte River. If it is not possible to avoid wetland impacts greater than 0.10 acre, an appropriate permit would be obtained from the USACE for wetland crossings. The project would follow all requirements from the USACE for wetland restoration. Mitigation measures would be implemented to restore wetlands in place immediately after pipeline construction is completed. The USACE would require wetland restoration in order to close a Section 404 permit. Prior to construction, wetland topsoil would be stockpiled. Where possible the ROW width would be reduced at wetland crossings. Post -construction, wetlands would be restored to preconstruction conditions and contours, wetland topsoil would be replaced, and the wetland would be reseeded with a representative seed mixture approved by the USACE. Wetland restoration should take one to two growing seasons. 4 2.4 Threatened, Endangered, and Special Status Species SWCA reviewed the list of federally listed species for Weld County, Colorado, available through the U.S. Fish and Wildlife Service (USFWS) website (USFWS 2017b) to determine the species that are evaluated in this report. In total, nine species are listed for the project area (Table 4). The USFWS also provides protection to avian species under the Migratory Bird Treaty Act (MBTA). The MBTA makes it illegal for anyone to take, possess, import, export, transport, sell, purchase, barter, or offer for sale, any migratory bird, or the parts, nests, or eggs of such a bird, except under the terms of a valid permit issued by the USFWS. Several avian species protected by the MBTA, including raptors, are likely to occur within the project area. Table 4.

SWCA also conducted qualitative comparisons of the habitat requirements of listed species with vegetation communities or landscape features observed in the project area during the field surveys. When an area met the habitat requirements of a listed species, that area was mapped in a geographic information system (GIS) format using a handheld GPS unit (Trimble). Within the surveyed portion of the route, two areas of potential Preble's meadow jumping mouse (Zapus hudsonius preblei) habitat were identified in the survey corridor. These areas are adjacent to Big Dry Creek and provide enough shrubs to be considered potential habitat. These locations are illustrated in Figure 2 of Appendix A. It is recommended that these areas be avoided via HDD or consultation with the USFWS may be necessary. The route does cross potential habitat for the Ute ladies' tresses orchid (Spiranthes diluvialis) and Colorado butterfly plant (Laura neomexicana var. coloradensis) at wetland crossings. There are no known locations of either plant species within 30 miles of the project area. 6 23 Other wildlife Species SWCA identified six raptor nests near the survey corridor along the surveyed portion. One of the nests is a known bald eagle (Haliaeetus leucocephalus) nest that was active at the time of survey; the remaining five nests were inactive at the time of survey and a follow-up survey is recommended prior to the beginning of construction to confirm the activity status of these nests. The bald eagle is protected by the Bald and Golden Eagle Protection Act and the MBTA. The pipeline is located within the 0.5 -mile buffer zone of the nest designated by the CPW. The CPW recommends restricting activities within 0.5 mile of an active bald eagle nest between the dates of November 1 and August. 15 (CPW 2008). The locations of these nests are illustrated in Figure 2 in Appendix A. Three white-tailed prairie dog (Cynomys leucurus) colonies are located partially within the survey corridor and have the potential to support nesting burrowing owls (Athene cunicularia). The CPW (2017) recommends performance of surveys to confirm the presence or absence of nesting burrowing owls to avoid inadvertent take (i.e.., disturbance, harassment, mortality). The boundaries of these colonies were recorded and their location is illustrated in Figure 2 in Appendix A. The project is located in an area with extensive human disturbance (agriculture, roads, houses). Wildlife species present include those that are adapted to human use and presence. Wildlife species that are common in the area include coyote; red fox; a variety of small mammals (deer mouse, house mouse, jackrabbit, cottontail rabbit); a variety of birds (meadow lark, mourning dove, house finch, English sparrow, homed lark, black -billed magpie, starling, American kestrel, red-tailed hawk, ring-necked pheasant, Canada goose, and other species); and a few reptiles (western terrestrial garter snake, gopher snake) and amphibians (bullfrog, leopard frog, spadefoot toad, tiger salamander) (Andrews and Righter 1992; Fitzgerald et al. 1994; Hammerson 1999). Grassland and wetland habitats that are crossed by the project provide good nesting habitat to a variety of migratory birds. Migratory bird nesting (non -raptor) generally starts in northern Colorado on or shortly after April 1 of each year. The MBTA prohibits the taking or destruction of all nests. Other species of federally protected migratory birds may nest in the project area, so any ground disturbance activities commencing after April 1 should be preceded by nesting bird surveys to ensure compliance with the MBTA. Project construction -related disturbance (traffic, noise, and increased human activity) could result. in the temporary displacement of wildlife near construction zones. Limited mortality of small and less mobile animals (small mammals, some reptiles and amphibians) could occur with construction, No long-term disturbance impacts would occur once construction along the ROW is completed and the ROW is restored. ROW restoration; preconstruction eagle, raptor, and burrowing owl surveys (if construction is proposed during the nesting season for these species); HIT of stream and canal crossings; and other mitigation/minimization and restoration measures proposed will help reduce impacts to wildlife and habitats. 7 2.6Cultural Resources SWCA completed a cultural resources review for the project (Burnett 2017). The resources review considered a 400 -foot -wide corridor centered on the pipeline for potential direct project effects, and a 1 -mile -wide corridor for potential indirect project effects. This review was completed in part using records and spatial data provided by the Colorado Office of Archaeology and Historic Preservation (OAHP). These records include information regarding previous archaeological inventories conducted in the area, along with information detailing the archaeological resources previously recorded. Included in this information are evaluations of the archaeological remains in terms of theireligibility for listing on the National Register of Historic Places (NRHP). In addition to the OAHP records, potential cultural resources were identified using historic General Land Office survey plats and land patents, along with historic U.S. Geological Survey (USES) topographic maps. The OAHP file search results identified 44 previously recorded sites or site segments within 1 mile of the proposed centerline, including six that are within 200 feet of the proposed centerline: three ditches, one railroad, one farm, and one transmission line. Two ditches are eligible for NRHP nomination. Additionally, the Steiber Farm is a listed Centennial Farm. Additional data are needed before an eligibility determination of the Hoyt to Terry Street Transmission Line can be made, and the remainder of the sites are not eligible for NRHP nomination. Of the 38 sites located between 200 feet and 1 mile from the project, 19 are eligible for NRHP nomination, need additional data before an NRHP determination can be made, or are designated Colorado Centennial Farms. Given the developed nature of the project area, no known cultural resources located between 200 feet and 1 mile from the proposed centerline would be adversely affected by the project. The 1863 GLO plats for Township 1 North, Range 66 West and Township 1 North, Range 67 West depict two potential site leads: a road labeled "Road to Denver" and the "Dry Creek Road." The southwest -trending Road to Denver parallels the southeast side of the South Plane River on the 1863 GLO plat. This location roughly corresponds to the modern U.S. Ilighway 85. At the approximate crossing of this road and the proposed pipeline, the entire area is disturbed by modern developments. The Dry Creek Road is mapped as paralleling the northwest side of Dry Creek on the 1863 GLO plat. It crosses the proposed pipeline in two places. These crossings are located in cultivated fields, and there is no trail trace visible on aerial imagery. As a result, no extant portions of the Dry Creek Road or the Road to Denver as mapped on the GLO plats remain within the project area. Several buildings and canals are mapped in the project vicinity on the historic 1949 to 1950 USGS topographic maps for the Hudson, Fort Lupton, and Frederick quadrangles. The buildings cannot be confirmed to be intact, but the canals are still intact and include those documented in the CARP records, along with several ditch segments that have yet to be formally recorded. This cultural resource review identified several ditch segments that are or may be contributing elements of NRHP-eligible resources that will be crossed by the project. These include one the Brantner Ditch (5WL2649.6), two of the Brighton Ditch (5WL2650.2 and 5 WL2650.3), Fulton Ditch OWL2245.9/5WL2245.14), and Lupton Bottoms Ditch (5WL2652.11). Additionally, one Union Pacific Railroad segment in Section 20, Township 1 North, Range 66 West, and nine County Roads (4, 6, 8, 19, 21, 23, 27, 29, and 31), along with Baseline Road, , and U.S. Highway 85 along the proposed pipeline corridor are potentially significant. 8 3.1 Proposed Mitigation and Minimization Measures Stream, Ditch, and Wetland Crossings • In areas with trenched wetland crossings the construction ROW would be reduced from 80 to 60 feet. Blading would occur only over the french line; the traffic lane would be matted with no vegetation disturbance. Construction vehicles would drive on the matted area. All stream and named ditch/canal crossing to be completed by HIED to avoid disturbance of stream and ditch bed and banks. • General Construction, Erosion Control, Restoration • Follow the Stormwater Management Plan (SWMP) and best management practices (BMPs) to minimize erosion, sedimentation, and dust during construction. • Complete restoration using recommended seed mixtures or landowner seed mixtures (non-agricultural lands). • Invasive and noxious weeds would be controlled after construction until the ROW is restored. • All drainage tiles will be located prior to construction by contacting landowners and local soil conservation agencies. • All roadway crossings and construction access points will be located to document and ensure that safe and accessible conditions exist throughout the construction phase. • All staging areas and extra workspace areas will be located prior to construction to ensure compliance with the SWMP. • Construction scheduling will be planned to minimize the length of time that open trenches and un-stabilized ROW (stripped of vegetation and not reseeded or mulched) is present. Restoration and revegetation will be scheduled as soon as possible following pipeline installation and burial. Ideally, revegetation/restoration will be completed immediately following pipeline construction. • Minimize blading of vegetation. Where possible, practicable, and safe, vegetation blading/clearing will be limited to the trench line and associated spoil area. Existing vegetation will remain in place; construction access will be by driving over existing vegetation. • Topsoil stockpiling. Prevent the mixing of topsoil and subsoil by using soil segregation methods. The top 6 to 12 inches (additional topsoil depth may be required across agricultural lands if requested by landowners) of topsoil will be segregated from the subsoil and stockpiled in a separate pile. Topsoil will be stripped and stockpiled from the ditch line and adjacent spoil areas. • Cut and crush vegetation. Traditionally, vegetation is cleared with a bulldozer down to bare soil across the entire construction ROW. In order to minimize disturbance and the need for extensive use of restoration treatments, the contractor will attempt to minimize the ROW width wherever possible. Where possible, vegetation will be crushed by track vehicles or cut with a brush hog instead of cleared. Clearing will be necessary over the trench and possibly the passing lane, depending on fire protection needs for welding operations. Additional disturbance may occur if soil padding is used to work over adjacent pipelines. Wherever blading occurs, topsoil will be salvaged, stored separately, 9 • • and protected. Cuts and fills to maintain grades will be minimized; any that are necessary will he blended with the existing terrain to maintain drainage and slope stability and to minimize potential visual impacts. All design, material, construction, operation, maintenance, and termination processes shall be in accordance with safe and proven engineering practices. The construction of the pipeline shall not inhibit public use of existing roads and trails, or inhibit wildlife or livestock movement. All equipment and vehicular access into the pipeline project will be confined to existing roads and the established ROW corridor. No major reconstruction or rerouting of these roads is intended. Construction sites shall be maintained in a sanitary condition at all times; waste materials at those sites shall be disposed of promptly at an appropriate waste disposal site. "Waste" means all discarded matter including human waste, trash, garbage, refuse, oil drums, petroleum products, ashes, and equipment. Wildlife and High Interest Species • A raptor nest survey will be completed if pipeline construction is scheduled for the raptor nesting season (January 15 to July 31). If active raptor nests are found near the ROW (within 0.3 mile) the CPW will be consulted to determine if any nest protection measures are needed. • The CPW and USFWS should be consulted regarding the active bald eagle nest near the project. Based on this consultation, appropriate mitigation will be determined to avoid a nest take. • A nesting burrowing owl survey will be completed if the identified prairie dog colony is proposed to be crossed during the period of owl activity (March 15 to October 31). If nesting burrowing owls are located, consultation with the CPW will occur to determine if any protection measures are needed.. • The CPW District Wildlife Manager for the area will be consulted prior to construction. If there any issues of wildlife mortality (entrapment in the trench, or other mortality) the District Wildlife Manager will be notified. Archaeology • On -call archaeologist and paleontologist would be available to consult if any potential archaeological (stone tools, fire rings, foundations, bones) or paleontological (fossils) are found during construction/excavation of the trench and ROW. Project construction would be temporarily stopped until review by the archaeologist/paleontologist. If needed the State Historic Preservation Office (SHPO) would be consulted. • Impacts to historic canal/ditch crossings would be avoided by completing these crossings using an HDD. 10 5.0 Literature Cited Andrews, R., and R.

Colorado EXECUTIVE SUMMARY Discovery DJ Services, LLC, contracted SWCA Environmental Consultants to complete a cultural resources review for 13.565 1.8015.08 linear miles of proposed centerline in the vicinity of Wattenberg, Weld County, Colorado for the Adams/Weld County Line to Fort Lupton Gas Plant pipeline. The resources review considered a 400 -foot -wide corridor centered on the pipeline for potential direct project effects, and a 1 -mile -wide corridor for potential indirect project effects. Discovery DJ Services provided the centerline via KMZ file format. As a partof this desktop review, a limited field reconnaissance was also conducted in proximity to wetland and waterbody crossings. No other field surveys were completed. The purpose of this review is to identify any significant cultural resource constraints associated with the development of the Adams/Weld County Line to Fort Lupton Gas Plant pipeline. This desktop review identified several ditch segments that are or may be contributing elements of National Register of Historic Places -eligible resources that will be crossed by the proposed pipeline. These include one segment each of the Brantner Ditch (5WL2649.6), two segments of the Brighton Ditch (5WL2650.2 and 5WL2650.3), 1.3), the Fulton Ditch (5WL2245.9/5WL2245.14), the Fulton Lateral Ditch (5WL2651.3), and Lupton Bottoms Ditch (5WL2652. ii). Additionally, one railroad segment in Section 20, Township 1 North, Range 66 West, nine 13 County Roads (4, 6, 6 '��, 6 1/2, 8, 10, 19, 21, 23, 27, 29, and 314), Avenue, East 1684+ Avenue, Baseline Road, Quebec Street, State Highway 7, and U.S. Highway 85 along this pipeline are potentially significant and therefore may be adversely affected by project construction. SWCA Environmental Consultants recommends boring the pipeline below these resources to avoid physical damage to the resources. The areas of highest potential for encountering previously undocumented buried archaeological deposits are the extensive intact alluvial deposits associated with the South Platte River and Big Dry Creek. 111 SWCA Desktop Cultural Resources Review Proposed Adams/Weld County Line to Fort Lupton Gas Plant Weld County.

Colorado INTRODUCTION Discovery DJ Services, LLC, contracted SWCA Environmental Consultants (SWCA) to complete a cultural resources review for the 13.561.80 5615..08 mile -long Adams/Weld County Line to Fort Lupton Gas Plant pipeline in the vicinity of Wattenberg, Weld County, Colorado. The resources review considered a 400 -foot -wide corridor centered on the pipeline for potential direct project effects, and a 1 -mile -wide corridor for potential indirect project effects (Figure 1). As a part of this desktop review, a limited field reconnaissance was also conducted in proximity to wetland and waterbody crossings. No other field surveys were completed. The purpose of this review is to identify any significant cultural resource constraints associated with the development of the Adams/Weld County Line to Fort Lupton Gas Plant pipeline. SWCA conducted a review of cultural resource records for the P1.80 -mile long Adams Weld County Line to Fort Lupton Gas Plant pipeline (Figure 1), including a file search through the Colorado Office of Archaeology and Historic Preservation (OAHP) COMPASS database on February 9, 2017 (File Search No. 19934). This review was performed to evaluate the nature of the historical occupation of the area and to assess the potential for previously unrecorded cultural resources. Additionally, SWCA reviewed General Land Office (GLO) maps, maps from the U.S. Geological Survey (USGS) U.S. Topa and Historical Topographic Map Collection, and aerial imagery. OAHP FILE SEARCH RESULTS The OAHP geographic information systems (GIS) records search identified 10-8 previous cultural resource inventories within 1 mile of the project centerline, seven of which are within 200 feet of the proposed centerline (Table 1). Three of these seven inventories were conducted for oil and gas projects, two were conducted for property inventories, one was conducted for a transmission line, and one was conducted for a rail yard. In this context, the current project is similar to previous work that has been conducted in the area. 1 SWCA Desktop Cultural Resources Review Proposed Adams/Weld County Line to Fort Lupton Gas Plant Weld County.

These include three ditches, one railroad, one farm, and one transmission line (Table 2). The dearth of documented prehistoric resources in the project vicinity is notable. Two ditches are eligible for National Register of Historic Places (NRHP) nomination. Additionally, the She ber Farm is a listed Centennial Farm. Additional data are needed before an NRHP 6 SWCA Desktop Cultural Resources Review Proposed Adams/Weld County Line to Fort Lupton Gas Plant Weld County. Colorado eligibility determination can be made for the Hoyt to Terry Street Transmission Line, and the remainder of the sites are not eligible for NRIIP nomination. Table 2.

The segment was originally recorded in 2006 by Heritage Resource Associates. For the current project, the proposed centerline parallels the east side of the ditch for 0.18 mile before heading east on the north side of County Road 8. The ditch was established in 1860 and is associated with the earliest water rights appropriation in this portion of the South Platte River. The ditch was used to supply irrigation water to farms in the area. Given this association with early agricultural development, the ditch has been determined to be eligible for NRHP nomination under Criterion A. Where the centerline parallels this ditch, there is a modern residence on the opposite side of the ditch, and the pipeline will extend through a cultivated field. Therefore, the construction -related disturbance to the surrounding setting will be limited and will be rapidly subsumed by the regrowth of vegetation and subsequentcultivation. Because the ditch will be physically avoided by project design, and the effects to the setting will be only temporary, the project will result in no adverse effects to this resource. A segment of tThe NRHP-eligible Fulton Ditch (5WL2245.9) is crossed by the proposed centerline. The---Ssegrnent 9 was originally recorded in 2012 by SWCA and is adjacent to the north side of the proposed disturbance. The earthen ditch was established in 1865 to supply irrigation water from the South Platte River to farms in the area. The ditch has undergone few changes and is one of the more extensive ditch systems in this portion of Colorado. The ditch has been determined to be eligible for NRI-1P nomination under Criteria A and C given its role in the early agricultural history of the area and because it represents a significant type, period, or method of construction. For the current project, the proposed centerline approaches the techniques will be used to cross the ditch. The right of way (ROW) disturbance to the i b vegetation and subsequent cultivation. Because the ditch will be physically avoided by project design, and the effects to the setting will be only temporary, the project will result in no adverse effects to this resource. 7 SWCA Desktop Cultural Resources Review Proposed Adams/Weld County Line to Fort Lupton Gas Plant Weld County. Colorado The Stie'ber Centennial Farm (5WL4301) is mapped as spanning the south half of Section 24, Township (T) 1 North (N), Range (R) 67 West (W), along the north edge of the town of Wattenberg. The farm was acquired in 1901 and includes a dwelling constructed in 1875, a bunk house and old garage constructed around 1925, a cow barn and milk house constructed in 1932, and a modern garage. The farm was not updated for the current undertaking and remains unevaluated for NRHP nomination. The currently proposed centerline runs through cultivated fields west of the structures before following the existing residential driveway and farm roads between two of the structures. The Steiber Farm will project design, with the pipeline placed a minimum of 300 feet north of the nearest building, on the opposite side of a fence. At this distance and with the fence adding an obstruction The pipeline will be placed in disturbed cultivated ground and the previously established roadway disturbance. Beyond the farmstead the line runs through uncultivated pasture land. Given these factors, the effects to the setting will be only temporary and between this Centennial Farm an4- pipeline ROW, the project will result in no adverse effects to this resource. The Hoyt to Terry Street Transmission Line (5WL3 154.2) is crossed at right angles by the proposed north -trending pipeline. This transmission line was originally recorded in 1988 by Associated Cultural Resource Associates, and was recommended to be not eligible for NRHP nomination at that time. It was subsequently recorded by Metcalf Archaeological Consultants, and was officially determined to be not eligible at that time, In 2007, this segment was recorded by ERO, at which point the NRHP eligibility was evaluated as needing data regarding structural elements that may contribute to its historic integrity. The pipeline will be placed through a cultivated field that has several well pads and associated facilities in the vicinity. While this resource may be found to retain elements of historic significance at some point in the future, the proposed pipeline will not physically affect any portion of the transmission line, and the associated ROW disturbance will be minimized following revegetation in the cultivated field. As a result, the project will result in no adverse effects to this resource. In addition to the sites or segments that are within 200 feet of the proposed centerline, 398 sites or site segments are between 200 feet and 1 mile from the proposed centerline. To assess the potential for indirect adverse effects to these resources, the sites/segments that are determined or recommended to be eligible for NRHP nomination, need data before an NRHP evaluation can be supported, or are Centennial Farms were isolated. Excluding one prehistoric open camp site (5WL318) where setting is not a contributing factor to its eligibility, 18 eligible resources remain (Table 3). Table 3.

I Yoxall Ditch Segment Needs data (officially) Considering the subsurface nature of the proposed pipeline and the existing level of modern disturbance in the area, SWCA recommends that none of the canal/ditch segments between 200 feet and 1 mile from the proposed centerline will be adversely affected by the project. Additional data are needed before the NRHP eligibility of Segment 3 of the Hoyt to Terry Street Transmission Line can be determined, but given the nature of the proposed disturbance, which will be over 0.75 mile from this segment, the project will result in no adverse effects to this transmission line. Two NRHP-eligible railroad segments are between 200 feet and 1 mile of the proposed project centerlines (see Table 3). Major obstructions such as county roads and highways are located between the proposed project centerline and these railroad segments. Given these settings, no railroad segments between 200 feet and 1 mile of the proposed centerline will be adversely affected by the project. One documented farmstead located between 200 feet and 1 mile from the proposed centerline that is eligible for NRHP nomination. The Shoen Farm (5WL1418) is a minimum of 0.4 mile from the proposed centerline, and other harm houses, cultivated fields, and County Road 29 are located between this farm and the centerline. As a result of this setting, the project will not adversely affect this farm. Given the developed nature of the project area, no known cultural resources located between 200 feet and I mile from the proposed centerline would be adversely affected by the project, and no further work is recommended for the current project. HISTORIC PROPERTY REVIEW In an attempt to identify significant historic properties not present in the OAHP records, SWCA reviewed historic maps of the project area, including the 1863 GLO plats for T1N, R66W and TIN, R67W, as well as historic topographic maps containing information mapped 9 SWCA Desktop Cultural Resources Review Proposed Adams/Weld County Line to Fort Lupton Gas Plant Weld County. Colorado between 1948 and 1949 (Bureau of Land Management 2016). The GLO plats depict very few features of potential significance. Two sets of site leads were generated from the GLO plats: a road labeled "Road to Denver" and the "Dry Creek Road." Colorado is crossed by a network of roads,streets, and various routes, many of which have been inexistence in some form since the earliest Europeans arrived in the state. The Colorado State Roads and Highways Multiple Property Listing (Autobee and Dobson -Brown 2003) provides definitions of these terms and a context for which these types of transportation routes evolved in Colorado. Many of these first roads tended to follow property lines and the section lines surveyed by the GLO (Autobee and Dobson -Brown 2003:E-52). In 1885, the Colorado General Assembly passed legislation that allowed county commissioners to declare any section or township line on the public domain a public highway; thus, the Weld County Commissioner in 1889 declared all such lines on the public domain in Weld County as public highways (Sievers 2015). Lands that were excepted include those lands that were granted to individuals or entities under the various Railroad Acts, the school sections (Sections 16 and 36 of every township and range), and the Homestead Act by 1889 (Sievers 2015). In the current project area, much of the land was not in the public domain. The 1 889 Right -of -Way Declaration, however, allowedlocal landowners to petition the Board of County Commissioners for a road ROW in order to construct a road, either along the section lines or some other line specified in the petition (Sievers 2015). Eleven Nineteen -undocumented, potentially historic named road segments have been mapped by the U.S. Census Bureau, Geography Division (2010) and cross in proximity to the proposed centerline and arc listed below: County Roads (4, 6, 8, 19, 21, 23, 27, 29, and 31), Baseline Road, and U.S. Highway 85. Most of these roads appear to have been upgraded and/or paved and remain in use today. In addition, the historic topographic maps and aerial imagery depict several unnamed two -track roads that cross -cut sections throughout the greater project area. 4-6-8- Avenue East 168th Avenue Baseline Road County Road 2 County Road 4 County Road 6 County Road 6 1 County Road 6 1/ County Road 8 County Road 10 County Road 19 County Road 21 County Road 23 County Road 27 County Road 29 County Road 31 State Highway 7 U.S. Highway 85 Quebec Street 10 SWCA Desktop Cultural Resources Review Proposed Adams/Weld County Line to Fort Lupton Gas Plant Weld County. Colorado The southwest -trending Road to Denver parallels the southeast side of the South Platte River on the 1863 GLO plat for T 1 N, R66W. This location roughly corresponds to the modern U.S. Highway 85. At the approximate crossing of this road and the proposed pipeline, the entire area is disturbed by modern developments. Another Road to Denver site lead is present on the 1863 GLO plat for T I N, R67W, but this road is on the west side of the South Platte River. This road is mapped only on the north edge of the plat for Ti S, R67W, and stops for an unknown reason. Where this site lead crosses the proposed pipeline, the entire surrounding area has been plowed, and no trace remains on modern aerial imagery. In these settings, there is no trace of the Road to Denver through the project area. The Dry Creek Road is mapped as paralleling the northwest side of Dry Creek on the 1863 GLO plat for T1N, R67W. It crosses the project area in two places on the proposed pipeline. These crossings are located in cultivated fields, and no trail trace is visible on aerial imagery. As a result, no extant portions of the Dry Creek Road or the Road to Denver as mapped on the GLO plats remain within the project area. Several buildings and canals are mapped on the historic topographic maps (USGS 1949a, 1949b, 1950, 1951). The canals are still intact and include those documented in the aforementioned files search, along with several ditch segments that have yet to be formally recorded. Where these corresponded with potential U.S. Army Corps of Engineers jurisdictional waters of the United States, field reconnaissance was performed and the canals/ditches were recorded accordingly (discussed below). The pipeline route crosses one segment of the Union Pacific Railroad that has not been previously recorded in Section 20, T1N, R66W. Based on aerial imagery, it appears that an abandoned section of railroad grade is located immediately west of the active track. SWCA recommends that HDD techniques be used across both the active and abandoned railroad grades to avoid physical disturbance to the historic railroad. Considering the well pads, roads, agricultural fields, buildings, and gravel operations in the vicinity, the visual disturbance caused by the proposed pipeline ROW is unlikely to significantly affect the setting in the vicinity of the railroad. By the late 1940s, several farmsteads had occupied the project vicinity (USGS 1949a, 1949b, 1950, 1951). Undocumented historic farm complexes are present in the project area and surrounding region and can best be understood within the context of The Historic Farms and Ranches of Weld County Multiple Property Listing (Whitacre and Simmons 1990). These types of sites are common throughout the region and demonstrate the early history of agricultural development in Weld County. These historic buildings cannot be entirely confirmed to be extant, but OAHP records for the few that have been formally documented indicate that both NRHP-eligible and not eligible farmsteads are present in the vicinity. Considering the current level of modern visual disturbance in the area, the proposed pipeline ROW is unlikely to result in significant indirect adverse effects to any NRHP-eligible farmsteads in the vicinity of the project. Aside from the canals and railroad segment, the historic map review identified no other significant potential historic resources in the project area vicinity that are not already identified in the OAHP records. 11 SWCA Desktop Cultural Resources Review Proposed Adams/Weld County Line to Fort Lupton Gas Plant Weld County. Colorado Results of a land patent search for the project area indicates that nearly half of the land patents were issued to the Union Pacific Railroad under the Union and Central Railroad Grant of 1862. Other land patents were issued under the Homestead Act of 1862, Sale -Cash Entry Act of 1820, the 1875 Colorado Enabling Act, the Scrip or Nature of Scrip Act of 1842, and the Scrip/Warrant Act of 1855. FIELD RECONNAISSANCE Several segments of ditches located at proposed centerline crossings were visited for the current project. Two segments of the Brantner Ditch (5WL2649.5 and 5WL2649.6), one two segment of the Brighton Ditch (5WL2650.2 and 5WL2650.3), one segment of the Brighton Lateral Ditch (5WL2182.12), one segment of the Fulton Ditch (5WL2245.14), one segment of the Fulton Lateral Ditch (5WL2651.3), and one segment of the Lupton Bottoms Ditch (5WL2652.11)1 and one segment of the McCanne Ditch (5WL945.5) were newly recorded. Attempts were made to visit the Fulton Ditch (5WL945) east of the South Platte River, but to be intact. As mentioned above, the previously recorded segment of the Fulton Ditch (5WL22'15.9) crossed by the proposed pipeline also could not be visited during the current project, but. SWCA recommends that by avoiding physical disturbance to this ditch, the project will result in no adverse effects to this ditch segment. One segment of the B•rantner Ditch that was newly recorded (5WL2649.5) extends southwest from previously recorded Segment 4 for a distance of approximately 725 feet to a property line. As described above, Segment 4 was determined to be a contributing portion of this NRHP-eligible ditch. Segment 5 is in the same condition and is therefore also recommended to be a contributing portion. The proposed pipeline will not cross this newly recorded ditch segment, but it will parallel the east side of the ditch along the extent of the segment in a cultivated field. As is recommended for Segment 4, SWCA recommends that by avoiding physical disturbance to this ditch, the project will result in no adverse effects to this ditch segment. The second segment of the Brantner Ditch that was newly recorded (5WL2649.6) is 0.8 mile south of Segment 5. This segment is approximately 900 feet long and is bounded to the south by County Road 6, and to the east by a property line. The proposed north -trending pipeline will cross the ditch by paralleling this property line through cultivated fields. Segment 6 is another intact segment of the Brantner Ditch, and is recommended to be a contributing portion of this NRHP-eligible ditch. SWCA recommends avoidance of project -related disturbances by boring to place the pipeline at a sufficient depth under this historic ditch. By paralleling the property line through cultivated fields, the project will result in no indirect adverse effects to this ditch segment. The first newly recorded segment of the Brighton Ditch (5WL2650.2) is approximately 0.91 mile long and is bound to the north by County Road 8 and to the south by a property line. The 12 SWCA DesktopCultural Resources Review Proposed Adams/Weld County Line to Fort Lupton Gas Plant Weld County. Colorado segment crosses Big Dry Creek and extends through cultivated fields. The proposed east - trending pipeline will cross the ditch by paralleling this property line through cultivated fields. Although this segment of ditch appears to be intact, additional data are needed for the ditch as a whole before an NRHP recommendation can be made. SWCA recommends avoidance of project -related disturbances by boring to place the pipeline at a sufficient depth under this historic ditch. By paralleling the property line through cultivated fields, the project will result in no indirect effects to this ditch segment. The second newly recorded segment of the Brighton Ditch (5WL2650.3) is 0.48 mile long bound to the west by County Road 23 and to the south by County Road 6. The segment occurs at the edge of a cultivated field. The proposed pipeline intersects this segment of the ditch in two places; once near the north end where the pipeline trends south and once near the middle where the pipeline turns to the east. The vast majority of this segment has undergone recent modification in the form of recontoured sidewalls and blading along the channel bottom. Although this maintenance has sacrificed the integrity of the ditch, additional data are needed for the ditch as a whole before an NRHP recommendation can be made. SWCA recommends avoidance of project -related disturbances by boring to place the pipeline at a sufficient depth under this historic ditch. By paralleling the property line through cultivated fields, the project will result in no indirect effects to this ditch segment. The segment of the Brighton Lateral Ditch that was newly recorded (5WL2182.12) is approximately 07541.2 miles long and is bound to the north by County Road 10 and to the south by County Road 8. The segment crosses through cultivated fields te the southwest and an o fen Jastures to the northeast. A well pad is located along the west side of this ditch segment. Historically, this ditch represented a minor expansion to an existing irrigation network, and as such, it did not play a significant role in the agricultural development of the county. The site was previously determined to be not eligible for NRHP nomination, and SWCA found no new information that would contradict this previous assessment. Therefore, no avoidance is recommended, and the project will result in no effects to this ditch. As mentioned above, a previously recorded segment of the Fulton Ditch (,5WL2245.9} is adjacent to the proposed pipeline. Newly recorded Segment 14 was documented to the south of Segment 9. This newly documented segment retains the same character as Segment 9, and therefore supports the eligibility of this NRHP-eligible resource. The proposed centerline approaches the ditch at right angles through cultivated fields, and horizontal directional drilling (HDD) techniques are recommended to be used to cross the ditch. The right-of-way (ROW) disturbance to the surrounding setting will therefore be limited and will be rapidly subsumed by the regrowth of vegetation and subsequent cultivation. Because the ditch will be physically avoided by project design, and the effects to the setting will be only temporary, the project will result in no adverse effects to this resource. One segment of the Fulton Lateral Ditch (SW L2651.3 ) was newly recorded. This segment parallels the east side of County Road 27. Previously recorded segments 1 and 2 are in a similar setting less than 0.5 mile to the south. These previously recorded segments support the NRHP eligibility of this resource. Newly documented Segment 3 retains the same character as 13 SWCA Desktop Cultural Resources Review Proposed Adams/Weld County Line to Fort Lupton Gas Plant Weld County. Colorado the previously documented segments, and as a result, this segment is also recommended to support the NRHP eligibility of the ditch as a whole. The historic setting of this ditch has been compromised by gravel mining operations and the modern improved County Road 27 immediately to the east. The proposed pipeline will parallel existing road disturbances, approaching the ditch at a right angle. Considering the amount of existing disturbance in the immediate vicinity, the ROW disturbance will not result in indirect effects to this resource. HDD techniques are recommended to cross the ditch (and adjacent County Road 27), which will allow the ditch to be physically avoided by project design, resulting in no adverse effects to this resource. The newly recorded segment of the Lupton Bottoms Ditch (5WL2652.11) consists of two forks branches. at the crossing of the proposed centerline, which merge into one ditch 544 feeth.59 mile north of the proposed centerline. Both branches are bounded to the north by property lines. The west branch is also bounded to the south by t • County Road 6z and the east (and main) branch extends south to the South Platte River. This newly recorded segment is bounded to the north and south by property lines. The Lupton Bottoms Ditch is eligible for NRHP nomination due to its significance to the early agricultural history of the region. This newly documented segment of ditch is unaltered and is recommended to contribute to this eligibility. SWCA recommends avoidance of project -related disturbances by boring to place the pipeline at a sufficient depth under this historic ditch. The proposed pipeline will parallel a property boundary in the vicinity of these crossings, but unlike the other canals crossed by this project that are located in cultivated fields, the Lupton Bottoms Ditch crossings extend through what appears to be an -unplowed pasture landsurtace. As a result, construction may temporarily alter the historic setting of this ditch until the surface is revegetated. One segment of the McCanne Ditch (5WL945.5) was newly recorded. This segment parallels the proposed pipeline for 850 feet between two property boundaries. An industrial storage yard is located west of the segment, and a former gravel :pit mine is located to the east. The pipeline crosses the north end of this segment, where a road grade has displaced the ditch remnants. There are no culverts, and it appears that the ditch had been abandoned prior to the construction of the road grade. The only remnant of this ditch to the north of this road grade is a concrete diversion, but the ditch does not continue beyond this diversion due to modern grading of the surrounding area. Historically, this ditch made a minor contribution to an existing irrigation network, and as such, it did not play a significant role in the agricultural development of the county. The site was previously determined to be not eligible for NRHP nomination, and SWCA found no new information that would contradict this Previous assessment. Therefore, no avoidance is recommended, and the project will result in no effects to this ditch. 14 SWCA Desktop Cultural Resources Review Proposed Adams/Weld County Line to Fort Lupton Gas Plant Weld County. Colorado GEOLOGIC FACTORS AFFECTING SITE POTENTIAL The project area is located in an area of predominantly low relief. Loamy Mollisols are the most common soil orders across the project area, followed by Alfisols, Aridisols, and Entisols (Esri and Natural Resources Conservation Service [NRCS] 2014). The latter appear to be limited to some dissected hills and valleys. The upland plains, which is the most common geomorphic setting crossed by the project, are prime farmland when irrigated (Esri and NRCS 2014). These soils typically exhibit a stable surface horizon overlying a pedogenically altered subsurface horizon(s). Although these soils may be generally favorable for the preservation of buried archaeological material, the major factor affecting this preservation is the agricultural development in the area, which has disturbed the upper soil horizons along the majority of the proposed pipeline. A few locations appear to contain intact soils, namely areas adjacent to the streams crossing the project area, as these have not been plowed. Considering this and the common presence of aggraded sediment adjacent to streams, these areas are the most likely to contain intact buried archaeological material. The major drainages crossing the project area are the northeast -trending South Platte River and Big Dry Creek. Extensive intact alluvial depositsare associated with both streams (Esri and NRCS 2014; Tweto 1979). These have the potential to contain deeply buried archaeological material. SUMMARY AND RECOMMENDATIONS This desktop review identified several ditch segments that are or may be contributing elements of NRHP-eligible resources that will be crossed by the proposed pipeline. These include one segment each of the Brantner Ditch (5WL2649.6), two segments of the Brighton Ditch (5WL2650.2 and 5WL2650.3), Fulton Ditch (5WL2245.9/5WL2245.14), the Fulton Lateral Ditch (5WL2651.3), and Lupton Bottoms Ditch (5WL2652.11). Two additional segments of the Brantner Ditch (5WL2649.4 and 5WL2649.5) parallel the proposed pipeline but will not be crossed. Additionally, one railroad segment in Section 20, T 1 N, R66W, nine County Roads (4, 6, 8, 19, 21, 23, 27, 29., and 31), Baseline Road, and U.S. Highway 85 13 County Roads (2, 4, 6, 6 'A, 6 'A, 8, 10, 19, 21, 23, 27, 29, and 34), 168th Avenue, East 1684+ Avenue, Baseline Road, Quebec Street, State Highway 7, and U.S. Highway 85 along this pipeline are potentially significant resources and therefore may be adversely affected by project construction. These canal and road segments are located in rural agricultural settings, but the temporary disturbance caused by pipeline construction is not anticipated to permanently alter the character of these surroundings, and by physically avoiding these resources through boring, SWCA recommends that the project will result in no adverse effects. The areas of highest potential for encountering previously undocumented buried archaeological deposits are the extensive intact alluvial deposits associated with the South Platte River and Big Dry Creek. In the event that such a discovery is made, SWCA recommends that the resource be formally recorded and evaluated for NRHP eligibility by a permitted archaeologist.
