Rocky Mountain Midstream, LLC 540 E Bridge Street Brighton, Colorado 80601 EAST GREELEY PIPELINE PROJECT APPLICATION FOR USE BY SPECIAL REVIEW USR QUESTIONNAIRE Planning Questions: 1. Explain, in detail the proposed use of the property. Proposed pipeline: East Greeley — PRE18rO341 UP TO 24 -INCH NATURAL GAS PIPELINE Response: The East Greeley Pipeline Project is a proposed up to 24" Natural Gas Pipeline that will connect Rocky Mountain Midstream, LLC's Fort Lupton Gas Processing Plant (U R 17-006 9) with the Keenseburg Gas Plant to increase production efficiency of both gas plants. The selected route is approximately 13.65 miles long and is deemed to be the most direct route, which will minimize impact on the community, minimize cost, and maximize safety during construction. This pipeline project begins at the proposed Latham Compressor Station, (PREI8-0299) in Weld County, 527 T5N R65W, Parcel # 096127000060 traveling East into Section 26 to the proposed Auburn Compressor Station (PRE 18-02 98) and then South through Sections 26 and 35 in T5 N R65W, continuing South through Sections 02, 11, 14, 23, 26, and 36 in T4N R65W, and further South through Sections 01 and 12 in T3N R65W connecting to the Milton North pipeline (USRIB-0007). Rocky Mountain Midstream, LLC is in the process of acquiring a 30 -foot wide permanent easement along the pipeline route, along with a 50 -foot temporary work space. Upon completion of the proposed Natural Gas Pipeline, all lands disturbed will be reclaimed to prior conditions. The up to 24 -inch natural gas pipeline will be constructed within the following Township, Range, and Sections. Rocky Mountain Midstream is in the processes of obtaining agreements with all of the landowners which the pipeline route traverses. Below is a list of the parcels of land which we are entering into agreement to, as well as two maps outlining the proposed pipeline route.

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 landowners' agreements. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. Response: Advances in oil and gas extraction technologies have resulted in a substantial increase in oil and gas activities across Colorado. Crude oil and produced liquids (condensate, produced water) from these wells impede the natural gas production and require transportation to oil and gas facilities for processing, treatment, and either disposal or sale to regional markets. Currently, these liquids are transported by truck from the individual well pads resulting in an increasing number of trucks per day on the local city and county roads and state highways. Similarly, the existing natural gas infrastructure in and around these wells is a capacity or doesn't exist within areas of new drilling. Centralized collection of these liquids and more efficient means of transportation are required to reduce the local truck traffic and facilitate transportation of the natural gas produced liquids to locations where they can be processed and sold to meet market demands. The Project is a necessary component of the overall system to gather, process, transport and market the area's natural resources in the Niobrara and CodeII formations. 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 pipeline meets the objectives outlined in the Weld County Code Comprehensive Plan without rezoning or changing the use of the land. The pipeline 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. Wilkarns. Rocky Mountain Midstream, LLC 540 E Bridge Street Brighton, Colorado 80601 Proposed pipeline: East Greeley — PRE1B-0341 UP TO 24 -INCH NATURAL GAS PIPELINE 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: Section 23-3-20 identifies that oil and gas production infrastructure is allowed as a use by right in agricultural zone districts. Section 23-3-40 identifies that oil and gas support, service, and pipelines are acceptable as a Use by Special Review in the district. Any impacts to actively cultivated land by the project will be temporary, and agricultural operations can resume once the pipeline is operational. The proposed pipeline meets the objectives outlined in the Weld County code Comprehensive Plan without rezoning or changing the use of the land. 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 proposed pipeline route is primarily located in unincorporated Weld County in the agricultural zone district. The surrounding land usage for the proposed route in question primarily consists of plowed fields, pivot irrigation systems, and country homes. The pipeline 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. 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. A total of 19 crossings, including county roads, section lines, railroad, and irrigation canals are required within Weld County. The table below summarizes the Weld County road crossings required along the preferred route. A complete list of other feature crossings along the preferred route is outlined in the following table.

Each HDD will begin, end and be of sufficient depth to ensure the pipeline is not subject t 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 (U SALE) 404 permit will not be necessary for this project. 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 top -spoiled, and the drive space will be matted with pipeline mats to mitigate disturbance. Elading 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, Rocky Mountain Midstream will obtain necessary ALOE 404 permits. Railroad Crossings: All railroad crossings will be completed in strict conformity with the railroad company's current engineering standards and specifications. 5. What are the hours and days of operation? (e.g. Monday thru Friday 8:00 a.m. to 5:00 p.m.). Response: During Construction 7 days a week, 6:00 a.m. to 6:00 p.m., after construction, this is an unmanned project. The hours of operation for the pipeline will be 24 hours per day, 7 days per week, 365 days per year. 6. List the number of fu l l time and/or part time employees proposed to work at this site. Response: During construction, approximately 30-40 construction personnel, including the construction contractor and Rocky Mountain Midstream's construction management team, will be required to construct the pipeline along the right-of-way. There will be 1 employee to perform the monthly/quarterly inspection/maintenance trip. The operation and maintenance of the pipeline will be performed by trained and qualified operators and pipeline technicians. 7. If shift work is proposed include the number of employees per shift. Response: No shift work is proposed.

Describe the type of lot surface and the square footage of each type. (e.g. asphalt, gravel, landscaping, dirt, grass, buildings). Res onse: The pipeline will be cut and filled with the original grading surface. The right-of-way will be re- seeded after completion of the pipeline to return the area to original condition. 11. How many parking spaces are proposed? How many handicapped (ADA) parking spaces are proposed? Ides onse: The pipeline will run within the right-of-way and will not require parking. 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 will be reseeded. Similarly, all wetland areas will be restored to pre -construction conditions and contours, topsoil will be replaced, and any wetlands will be reseeded. Wetlands should return to pre - construction conditions within 1-2 growing seasons. Permanent erosion control measures will be installed as required and seeding will occur in accordance with landowner requirements. Invasive and noxious weeks will be controlled after construction to minimize further propagation pursuant to Chapter 15, Articles I and I I 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). Feseonse: The pipeline will be below grade and therefore not require a fence. 14. Describe the proposed screening for all parking and outdoor storage areas. If the site is located in a floodplain i n outdoor storage is restricted. Response: Because no parking or storage areas are associated with this project, no screening will be necessary. Williams. Rocky Mountain Midstream, LLC 540 E Bridge Street Brighton, Colorado 80601 Proposed pipeline: East Greeley — PRE1B-0341 UP TO 24 -INCH NATURAL GAS PIPELINE 15. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. Response: During operations 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 blown down utilizing blowdown valve(s). 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 pipeline once it is 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 LaSalle Fire Protection District provides fire protections to this area. Rocky Mountain Midstream maintains an ongoing working relationship with these fire districts and will reach out to them to review the upcoming project to review Rocky Mountain Midstream's emergency response plan. The pipeline will be covered under an Emergency Response Plan. The pipeline will be designed and constructed per code. Control and shut off valves will be strategically placed along the pipeline route and are required to be inspected twice a year on our mainline system. Overpressure protection devices will be installed and inspected annually or as required by code. Additionally, a hydrostatic test will be performed prior to start up. The pipeline will be protected with a leak detection system and monitored by a 24 -hour control room through a SCADA system. The pipeline will be identified through pipeline markers. The pipeline will be cathodically ca I ly protected to mitigate corrosion as well as above ground portions will be inspected through an atmospheric inspection program. Company employees are covered under training programs, including our Operator Qualification Program. Moreover, the company follows a detailed Public Awareness program. Rocky Mountain Midstream maintains an emergency response plan (copy included) which addresses responses to leaks or spills. This response plan contains detailed information on the steps needed to address any emergency event reasonably anticipated to be encountered during pipeline operations. The response plan contains contact information, detailed step by step s pillfleak response information, emergency phone numbers for local responders and spill/leak contractors. The response plan is reviewed on a regular basis. 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: Cleanup and restoration will occur after the pipeline is installed and backfill is completed. Cleanup of the surface along the construction right-of-way will include removal of the construction debris and final grading to the finished contours. Permanent erosion control measures will be installed as required and seeding will occur in accordance with landowner requirements. Invasive and noxious weeds will be controlled after construction until the right-of-way is restored. Rocky Mountain Midstream, LLC 540 E Bridge Street Brighton, Colorado 80601 Engineering Questions: Proposed pipeline: East Greeley — PRE18-0341. UP TO 24 -INCH NATURAL GAS PIPELINE 1. Describe how many roue dtripslday 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). The project will not impact the existing transportation network. The temporary increase in traffic during construction will be more than offset by the decrease in truck transport traffic associated with the crude oil and liquids production compared to the respective pipeline capacities over the life of the Project. 2. Describe the expected travel routes for site traffic. Response: During construction, the primary travel route to access the pipeline will be from Rocky Mountain Midstream, LLC's Keenseburg Laydown Yard located at: 8490 CR 57, Keenseburg, CO. Traffic will travel primarily from Keenesburg, traveling west on WCR 18 to WCR 49. Traffic will then travel north on WCR 49 to WCR 84.8 heading west to WCR 47 and then traveling north on WCR 47 to various access points along that portion of the pipeline route. Traffic will then travel west on WCR 52 to WCR 45 where traffic will then head north to the final section of the pipeline route.

All steel pipelines constructed to 49 CFR Part 192/195 DOT standards for gas or crude oil pipelines. The natural gas pipeline will be constructed of API 5L, X-65 pipe, with a 0.375" wall thickness for the line pipe and a 0.500" wall thickness for all crossing pipes. The pipe will be coated with fusion bond epoxy for external corrosion protection. All city and county road, and other crossings will be crossed by either bore or horizontal drill ("HOD'), thereby avoiding surface impacts in these areas. Rocky Mountain Midstream will comply with a l l requirements for construction within unincorporated Weld county, the ditch companies, railroad company, as well as the Nationwide Plan 12 permit for all waterway crossings, which allow waterways to be open cut or bored depending on the condition of the waterway. The following table summarizes key information for the natural gas pipeline. East Greeley Natural Gas Pipeline U # to Pipeline Diameter Line Pipe Wall Thickness Crossing Pipe Wall Thickness Yield Strenith 65,000 psi - wade) Approximate pipeline length 1 miles Total Parcel / Tract Count 29 All pipelines will be buried to provide 48 -inch 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 will be lowered into the trench and backfilled. The pipeline 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 form the underlying subsoil and stored along the construction right-of-way until the trench is backfilled. During construction, Discovery will follow BMP's described in the Stormwater Management Plan. Erosion control BMPs include silt fencing, straw wattles, hay bales, or combinations of these items, depending on the particular 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 location of access road entry points will be properly marked. Flagging, signs, and other markings identifying the limits of disturbance would be maintained through all phase of construction. A survey crew would be available during construction to replace any stakes that have been damaged or inadvertently removed. Wiliiam&,0•1060er Rocky Mountain Midstream, LLC 540 E Bridge Street Brighton, Colorado 80601 Proposed pipeline: East Greeley — PRE18-0341 UP TO 24 -INCH NATURAL GAS PIPELINE Clearing andGrading: 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, facilities seeding establishment, and protect the construction right-of-way. Stumps that are not shredded or shipped 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 would be placed on the banks of the drainages. Gaps will be left periodically in the topsoil and subsoil piles to avoid pending 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. Access will provide 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 -miles 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 soils 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. CULTURAL RESOURCE REVIEW OF THE PROPOSED GREELEY DISCHARGE PIPELINE, WELD COUNTY, COLORAD DECEMBER 21, 2018 PREPARED FOR Rocky Mountain Midstream PREPARED WY' MCA Environmental Consultants CULTURAL RESOURCE REVIEW OF THE PROPOSED GREELEY DISCHARGE PIPELINE, WELD COUNTY, COLORADO Prepared for Rocky Mountain Midstream 7859 Walnut Hill, Suite 335 Dallas, Texas 75230 Prepared by Stephanie Slaughter SWCA Environmental Consultants 295 Interlocker Boulevard, Suite 300 Broomfield, Colorado 80021 (303) 487-1183 www.swca.com SWCA Cultural Resources Report No. 18-846 December 21, 2018 Cultural Resource Review of the Proposed Greeley Discharge Pipeline, Weld County, Colorado EXECUTIVE SUMMARY Rocky Mountain Midstream contracted SWCA Environmental Consultants (SWCA) to complete a desktop cultural resource review for 10.70 linear miles of the proposed Greeley Discharge pipeline southeast of Greeley, Weld County, Colorado. The resource review considered a 400 -foot -wide corridor centered on the pipeline centerline for potential direct project effects and a 1 -mile -wide corridor for potential indirect project effects, Rocky Mountain Midstream provided the centerline via KMZ file format. As a part of this desktop review, SWCA conducted a limited field reconnaissance of 10 locations in proximity to areas that are potential jurisdictional waterbody crossings regulated by the U.S. Army Corps of Engineers and subject to compliance with Section 404 of the Clean Water Act. SWCA completed no other cultural resource field surveys. The purpose of this review was to identify any significant cultural resource constraints associated with the development of the pipeline. During the field reconnaissance, S'P'CA, additionally identified three segments of two historic county roads (County Roads 42 and 47), one segment of a historic irrigation ditch (Gilmore Ditch), one newly identified bridge over the historic irrigation ditch, and one previously recorded bridge over the historic irrigation ditch (5WL3063). 3). The desktop review revealed 148 known cultural resources that may be impacted by this project. These include 14 potential historic roads (Weld County Roads 34 5, 38, 40, 42, 43.5, 44 and State Highway 256, 45, 46, 47, 48, 49, 50, 52, and 54), both recorded (n = 8) and unrecorded (a _ 6) segments of six National Register of Historic Places (NRHP)-eligible irrigation ditches (Gilmore Ditch, East Neres Canal, Morrison Seep Ditch, Lower Latham Outlet Ditch, Union Ditch, and Latham Ditch), one unrecorded segment of an irrigation ditch (West Neres Canal) that is not eligible for the NRIIP, six undocumented and unnamed ditch segments, one undocumented historic reservoir (Lower Latham Reservoir), one undocumented segment of an abandoned NRIIP-eligible railroad grade (Colorado Central Railroad/Union Pacific Railroad, La Salle to Julesburg Branch), one previously recorded abandoned railroad siding (Auburn Siding) that is not eligible for the N P, one supporting segment of an NRHP-eligible transmission line (Kiowa Creek to Weld Transmission Line), one residence (Vetting House) that is not eligible for the RHF', one historic trash dump (5WL883) 83) that is not eligible for the INTRUP, one prehistoric open camp (5WL50) that is not eligible for the NRHP, one prehistoric open camp (5WL902) of unknown NREP eligibility, one prehistoric burial (5WL52) of unknown eligibility, three undocumented schools (Auburn School, Beebe Draw School, and Sky View School), three undocumented mines, one undocumented cemetery, and 103 undocumented farmsteads in the review area. Considering the disturbed nature of the landscape from oil and gas and modern development and the temporary nature of the disturbance associated with pipeline construction, the project would have no adverse indirect impact on the surrounding farmsteads, irrigation ditches and reservoir, transmission line, or other resources within 1 mile of the proposed centerline, SWCA recommends using boring to avoid physical damage to the historic Gilmore Ditch and the historic Colorado Central Railroad Union Pacific Railroad grade and to prevent any potentially adverse impacts. Should development change and the Gilmore Ditch be open -cut rather than bored, SWCA recommends returning it to pre -construction conditions within 30 days of completion of any trenching, spanning, or boring to avoid any potential impacts as the ditch has not been formally evaluated for NRIIP eligibility for the current project. By adhering to these avoidance measures, construction and operation of the Greeley Discharge pipeline should result in no adverse effects to significant known historic properties. No areas within the review i Cultural Resource Review of the Proposed Greeley Discharge Pipeline, Weld County, Colorado area possess a high potential for containing previously undocumented buried archaeological deposits, although the northern end of the pipeline route crosses the Kersey Terrace, which has a moderate potential for containing previously undocumented buried archaeological deposits. ii Cultural Resource Review of the Proposed Greeley Discharge Pipeline, Weld County, Colorado CONTENTS Executive Summary ', •se011*�lsesss0s11ses�l11111111•!ss11sss11s11sss1111�rssssss�r�aiR�ii�sisiil�Eiaa�i��asss�iiiiiri�+*4#*44ii�#44#fi444r�444►�*+!w!!f*rslassrsffsMsr/ssrrsss� i Introduction •••••••••••0410.440.04104441ifilli anti nellnegell 110000600,111101111001,00111141MUIPS1 memo1110111100411.0011aiiit114i4ii4i44.4.44440#f4t.4fflf•ss/s**•1 +)AHP Files Search ResultsMenif#41040444040440fi044it004*41011*eel110esee/sssess1111seessess11s■1111sss11s11o.111144«ss11iisss44mi4444if#4+ff#4#i#4tif S Historic Property ' evie sass.; I is iii Aaa a a iii i iai &&&& i •iiiT_•-*..T_T•err, 8 Field Reconnaissance nod ******El4444.04#440/4f#4i*1044tt1044i004if8eve leesseerentio soes•!11!#11ies1011*ir•••••••liiissesessiiit11f#44f000*44i0044Ff0*0•*4 J' Geologic Factors Affecting Site Potential •*R4ii+044444#f444i4ff#444i44446•11114eeeegsesl0sees*ssees*ssees11ssssspSes11411*ls44•*sseesses#Fi4 10 Summary and L •�J k3 Q14 Ft11�r�Rssi4411airRs�sll��li rii��-��l�W�l�l!!��!!�#T!�!!#!�!1 !M!�!!lill Ri�11!!!!!!ill!1lFR-!!!!llRiliiiiii!lliiii�iiiti i-iiiin �� References l +e f4444iff4444f44444i.i*44se01111esesl111111se11srses0+11111111!1111111111/111111111111/114s11ss11ssss11s4.ss+rssr444ss11iis i114rsiF+f#44f044t10i4i044feel011ssel0se0less 13 Figures Figure 1.

The proposed pipeline would traverse private land in Sections 1 and 12 of Township (T) 3 North (N), Range (R) 65 West (W), Sections 1, 2, 11, 12, 14, 23, 25, 26, 35, and 36 of T4N, R65W, and Sections 35 and 36 of T5N, R65W. The purpose of this review was to identify any significant cultural resource constraints associated with the development of the pipeline. The resource review considered a 400 -foot -wide corridor centered on the pipeline centerline for potential direct project effects and a 1 -mile -wide corridor for potential indirect project effects. Rocky Mountain Midstream provided the centerline via KMZ file format. SWCA conducted a review of cultural resource records for the area of consideration, including a file search through the Colorado Office of Archaeology and Historic Preservation (OAS) COMPASS database on December 4, 2018. The purpose of this part of the review was to evaluate the nature of the historical occupation of the area and to assess the potential presence of previously unrecorded cultural resources. Additionally, SWCA reviewed General Land Office (GL O) maps, maps from the U.S. Geological Survey (USGS) US. Topo and Historical Topographic Map Collection, and aerial imagery. As part of this review, SWCA also conducted a limited field reconnaissance of 10 locations near areas that are potential jurisdictional waterbody crossings regulated by the U.S. Army Corps of Engineers (DACE) and subject to compliance with Section 404 of the Clean Water Act (Figures 2 and 3). SWCA completed no other cultural resource field surveys. The purpose of this review was to identify any significant cultural resource constraints associated with the development of the pipeline.

Two previous linear inventories intersect the current project centerline: one near the southern portion of the proposed centerline, and one near the north -central portion. These inventories were conducted for the High Plains Gas Pipeline Expansion project (OAHP Report No. MC.E.RSS) and the La Salle Pipeline Project (OAHP Report No. WL.E.R48). Table 1.

USDA Natural Resources Conservation Service The OAHP` file search results identified 18 previously recorded sites or site segments within 1 mile of the proposed pipeline centerline. These 18 resources are summarized in Table 2 along with their recommendation of eligibility for inclusion in the National Register of Historic Places (NRHP). One site, 5WL883, a historic trash dump, has been mapped in the OAHP records near the north -central portion of the proposed route and is crossed by the pipeline centerline. One site, 5W1,3063, a Gilmore Ditch Bridge, is mapped in the °ARP records at the intersection of the Gilmore Ditch and County Road (R) 42. This site is not crossed by the pipeline centerline, although it is within 150 feet of the centerline. The OABP records show no other sites or site segments mapped within 200 feet of the proposed centerline. Two of the previously recorded sites mapped between 200 feet and 1 mile of the proposed pipeline centerline are prehistoric open camps and one site is a prehistoric burial. The remaining 13 sites mapped between 200 feet and 1 mile of the proposed centerline are all historic and include the Auburn Siding of the Julesburg Branch of the Colorado Central Railroad/Union Pacific Railroad, one railroad segment, one historic residence, one segment of the Union Ditch, two segments of the Lower Latham Outlet Ditch, four segments of the Gilmore Ditch, one bridge over the Gilmore Ditch, one segment of the Morrison Seep Ditch, and one segment of the Kiowa Creek to Weld Transmission line. The location of the historic residence, the Vetting House (5WL1535), 5), is unclear, with the mapped location in the OAHP records at a different locale than that described in the site form. In either case, the site is between 200 feet and 1 mile from the proposed pipeline centerline. Table 2.

Both of these sites are more than 400 feet from the proposed pipeline centerline and are noted to be currently inundated by the Lower Latham Reservoir. The remaining prehistoric open camp is recommended not eligible for inclusion in the iRHP, as are five of the historic sites including the Auburn Siding, a trash dump, a residence (the Vetting House), and two bridges over the Gilmore Ditch. The residence is recommended not eligible with OAHP concurrence. In Colorado, linear historic sites that have not been recorded in their entirety are generally recommended as Needs Data and the resource is treated as eligible. Each segment is assessed as supporting or not supporting the eligibility of the entire resource. Although some of the canal and railroad segments are listed in the COMPASS database as either eligible or not eligible, the overall pattern suggests that the majority of the resources are classified as Needs Data and am segments recommended eligible and therefore can be presumed to represent supporting segments, while segments recommended not eligible can be presumed to represent non -supporting segments. The Julesburg Branch of the Colorado Central Railroad/Union Pacific Railroad is recorded in the COMPASS database as eligible, and the one recorded segment within 1 mile of the pipeline centerline is recommended as supporting the eligibility of the overall linear resource. The Gilmore Ditch is recorded in the COMPASS database as both eligible and needs data; of the four recorded segments within 1 mile of the pipeline centerline, two are recommended as supporting, one with OAHP concurrence, one is recommended as non -supporting, and one is listed simply as needs data, with OABP concurrence. The Lower Latham Outlet Ditch is recorded in the COMPASS database as eligible, and one of the two recorded segments within 1 mile of the pipeline centerline is recommended as supporting the eligibility of the overall linear resource. The Morrison Seep Ditch is recorded in the COMPASS database as not eligible, and the one recorded segment within 1 mile of the pipeline centerline is recommended as non - supporting, with. OAHP concurrence. The Union Ditch is recorded in the COMPASS database as eligible, and the one recorded segment within I mile of the pipeline centerline is recommended as non -supporting. Finally, the Kiowa Creek to Weld Transmission Line is recorded in the COMPASS database as eligible, and the one recorded segment within I. mile of the pipeline centerline is recommended as supporting. One previously recorded segment of the N. HP -eligible Julesburg Branch of the Central Colorado Railroad Union Pacific Railroad (5 wL294 .1) is between 200 feet and 1 mile of the proposed pipeline centerline. The route crosses an unrecorded segment of the railroad. This portion of the railroad stretches between the small towns of La Salle to the southwest and Kersey to the east; the area surrounding the unrecorded railroad segment crossed by the pipeline route is in a landscape of scattered farms and developing oil and gas facilities near the edge of the encroaching development from the nearby cities of Evans and Greeley. Given the temporary nature of the aboveground disturbances associated with the construction of the pipeline and the surrounding development, the project would not adversely affect this railroad. Four previously recorded segments of the NRBP-eligible Gilmore Ditch (5 L5 18) are between 200 feet and 1 mile of the pipeline centerline. All four of these recorded segments are near the north -central and northern portions of the proposed pipeline route, and all are located to the east of the route. The ditch traverses a landscape that is largely agricultural with developing oil and gas facilities and infrastructure, as well as encroaching residential development from the nearby urban center of Greeley. The route crosses an unrecorded segment of the ditch that is adjacent to a developed feed lot. The disturbance associated with pipeline construction would be temporary and would not result in indirect effects to this historic resource. The remaining three NMHP-eligible sites are more than 200 feet from the proposed pipeline centerline. Given the developed nature of the project area, no known cultural resources between 200 feet and 1 mile 7 Cultural Resource Review of the Proposed Greeley Discharge Pipeline, Weld County, Colorado of the proposed centerline would be adversely affected by the project, and SWCA recommends no further cultural resource work for these sites in consideration of the current project. Historic Property Review In an attempt to identify significant historic properties not present in the OAP records, SWCA reviewed historic maps of the project area, including the 1865 GLO plat for T5N, R65W, the 1868 GLO plats for T3N, R64W and T4N, R64W, and the 1872 GLO plat for T3N, R65W and T4N, R65W (Bureau of Land Management 2018). SWCA also rev ie ed historic topographic maps containing information mapped between 1902 and 1952. The GLO plats depict no structures, railroads, ditches, or transmission lines within the vicinity of the pipeline centerline. One road labeled ROAD FROM EVANS TO BOX ELDER is depicted on the 1872 plat for T4N, R65W, and shown crossing the pipeline route in Section 14, Colorado is crossed by a network of roads, streets, and various routes, many of which have been in existence 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 how 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 in the public domain a public highway; thus, the Weld County Commissioner declared all such lines in the public domain in Weld County as public highways in 1889 (Sievers 2015). Lands that were excepted include those lands that were granted to individuals or entities under the various Railroad Acts, school sections (Sections 16 and 36 of every township and range), and those granted under the Homestead Act by 1889 (Sievers 2015). In the current project area, much of the land was not in the public domain. The 1889 Right -of -Way declaration, however, allowed local landowners to petition the Board of County Commissioners for a road right-of-way (ROW) to construct a road, either along the section lines or some other line specified in the petition (Sievers 2015). The USGS has mapped 14 potentially historic named roads near the proposed pipeline centerline: CRs 34.5, 38, 40, 42, 43.5, 44 and State Highway 256, 45, 46, 47, 48, 49, 50, 52, and 54. All 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 gravel roads and residential access roads that cro s s sections throughout the greater project area. The pipeline centerline would cross eight of the county roads: CRs 38, 40, 42, 44 and State Highway 256, 46, 47, 48, and 52. The surrounding area was relatively unoccupied as late as 1902. Few farmsteads occupied the project vicinity and were concentrated near the north end closer to Kersey, the Julesburg Branch of the Union Pacific Railroad, and the South Platte River. The Union and Latham Ditches are present, but most of the irrigation infrastructure (major ditches, smaller feeder ditches, and reservoirs) are not depicted on the 1902 map in the vicinity of the project (USGS 1902). An 1889 Weld County Road Rights -of -Way map book shows the presence of the Julesburg Branch of the Union Pacific Railroad, a ditch labeled PLATTE VALLEY CANAL that generally follows the current route of the Gilmore Ditch, and the modern configuration of county roads (Weld County 1889). By 1937, the irrigation infrastructure was largely present, with the Lower Latham Reservoir present, as well as the numerous ditches feeding into and out of the reservoir, as well as the modem names on the larger ditches such as Gilmore, Lower Latham Outlet, Union, and Latham (Works Progress Administration 1937). Two branches of the Neres Canal, identified in theCOMPASS files and on later topographic maps as the West Neres and the East Neres, are also present and in use on the 1937 map. By 1950, though, the West Neres Canal had been abandoned and Cultural Resource Review of the Proposed Greeley Discharge Pipeline, Weld County, Colorado appears on the later topographic maps as WEST NERES CANAL (ABANDONED) (USGS 1951a). By this time, the canal does not even show as a line on the adjacent map (USGS 195 1b). By 1950, the landscape had been transformed, with additional clusters of buildings depicted on the 1950 and 1951 topographic maps, likely corresponding to farmsteads, and mostly concentrated at the north end of the project vicinity. The additional buildings include at least three schools (the Auburn School, Beebe Draw School, and Sky View School), one cemetery, and three coal mines within 1 mile of the project. Undocumented historic farm complexes exist in the 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. 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. For lands within the project area vicinity, 27 land patents were issued to individuals under various acts. Most of these patents were issued to individuals under the Homestead Act of 1862, with several issued under the Sale -Cash Entry Act of 1820, the Timber Culture Act of 1873, and the State Grant, Agricultural College Act of 1862. One land patent was issued to the State of Colorado under the Colorado Enabling Act of 1875. The remaining land patents were issued to the Union Pacific Railroad under the Union and Central Railroad Grant of 1862. FIELD RECONNAISSANCE SWCA conducted a limited field reconnaissance of 10 locations in proximity to areas that are potential jurisdictional waterbody crossings regulated by the USACE and subject to compliance with Section 404 of the Clean Water Act. Two segments of CR 47, one segment of CR 42, one segment of the Gilmore Ditch, and one bridge were newly identified; and one previously documented bridge was identified in the vicinity of these waterbody crossings. The two newly identified segments of CR 47 pass through a rural part of Weld County that contains plowed fields and widely distributed farmsteads, residential development, and oil and gas infrastructure. On June 7, 1939, the State Board of Land Commissioners granted a ROW for a county road or public highway along the east boundary of Section 36 in T3N and T4N, R65W. The section was granted a ROW on the condition that a road would be constructed within 2 years (Weld County GIS 2018). Currently, the ROW for CR 47 remains in the public domain and is maintained by the county (Weld County GIS 2018). These segments of CR 47 are depicted in their current location and position on the 1937 Weld County Road ROW map (Works Progress Administration 1937), and the 1951 topographic maps (USGS 1951 b, 1951 c). Although the segments are part of a larger transportation network of farm -to -market roads, the route was one small part of the overall agricultural economic development in Weld County. However, because the entirety of this road has not been fully documented, additional data are needed to determine if the resource is significant. These segments have been widened and upgraded since 1937, affecting the historic integrity of the road, and SWCA recommends no further cultural resource work for these parts of the resource. The route of the pipeline centerline parallels both of these road segments along a corridor previously disturbed by continued road maintenance, Disturbance associated with pipeline construction would be temporary and would not result in effects to these historic road segments. The one visited segment of CR 42 is similar to CR 47 and passes through a rural part of Weld County dominated by agriculture, with widely distributed farmsteads, residential development, and oil and gas infrastructure. Citizens of Weld County petitioned for a 12 -mile -long east -trending road starting at the northwest corner of Section 27, T4N, ROW on July 18, 1887 (Weld County GIS 2018). A road viewers' report was approved and the road was declared a public highway on October 8, 1887 (Weld County GIS 9 Cultural Resource Review of the Proposed Greeley Discharge Pipeline, Weld County, Colorado 2018). This segment of CR 42 is depicted in its current location and position on the 1889 Weld County Road ROW map (Weld County 1889), and the 1951 topographic maps (USGS 1951 b, 1951c). Although the segment is part of a larger transportation network of farm -to -market roads, the route was one small part of the overall agricultural economic development in Weld County. However, because the entirety of this road has not been fully documented, additional data are needed to determine if the resource is significant. This segment has been widened and upgraded since 1889, affecting the historic integrity of the road, and SWCA recommends no further cultural resource work for this part of the resource. The route of the pipeline centerline crosses the road perpendicular and then parallels the road segment along a corridor previously disturbed by continued road maintenance. Disturbance associated with pipeline construction would be temporary and would not result in effects to this historic road segment. SWCA visited one segment of the Gilmore Ditch during the field reconnaissance for this project. The segment is in a cultivated field surrounded by widely distributed farmsteads, residential development, and oil and gas infrastructure. The visited segment is approximately 3,210 feet long, between 30 and 40 feet wide, and between 5 and 15 feet deep. The Gilmore Ditch originates at Milton Reservoir east of Platteville, Colorado, and provides water to irrigate farms and recharge underground wells in the area. The ditch terminates in Box Elder Creek. The Gilmore Ditch is the only structure used to transport water from Milton Reservoir to the lands owned by the Farmers Reservoir and Irrigation Company (FRICO) in Beebe Draw (Bott and Turner 2006; Colorado Division of Water Resources 2015). The Gilmore Ditch is part of the early irrigation district in Weld County, and portions of the Gilmore Ditch have been previously recorded and determined eligible for inclusion in the NRHP. SWCA recommends avoidance of project -related disturbances by either boring or returning the ditch segment to pre -construction conditions within 30 days of completion of the trenching, spanning, or boring. The segment is in an agricultural field and between two livestock feedlots; the disturbance associated with pipeline construction would be temporary and would not result in indirect effects to this historic resource. SWCA encountered two bridges spanning the Gilmore Ditch. One bridge is a previously recorded cultural resource, 5WL3063, , and located on CR 42 just east of the intersection with CR 47. The bridge is a steel stringer type bridge constructed of steel I -beams creating the deck and concrete wing walls, built in 1955. This bridge has been recommended as not eligible for inclusion in the NRHP. Given the temporary nature of the disturbance associated with pipeline construction, the project would not result in indirect effect to this historic resource. The second bridge SWCA visited is newly identified and located on CR 47. This bridge is similar to 5WL3063 in style and construction. The bridge is a steel stringer type likely built in 1955 and constructed of steel I -beams creating the deck and with concrete wing walls. The bridge has not been formally documented, thus additional data are needed to determine if the resource is significant. As currently designed, the pipeline route will avoid the direct impacts to the bridge, and the disturbance associated with pipeline construction would be temporary and would not result in indirect effects to this historic resource. GEOLOGIC FACTORS AFFECTING SITE POTENTIAL The project is in an area of low, rolling plains, generally trending along the edge of a hilly, upland area dominated by sand hills, with the north end terminating on the Kersey Terrace, a Pleistocene -age terrace of the South Platte River that has yielded a number of cultural sites, including several Paleoindian-age sites, although none are within 1 mile of the current proposed pipeline. The pipeline centerline crosses six types of soil: Aquolls and Aquents, Iacono clay loam, Nelson fine sandy loam, Olney fine sandy loam, Valent sand, and Vona loamy sand (Natural Resources Conservation Service 2018). These sediments vary from fine sandy loam to silt loam to clay and have weathered from underlying Cretaceous- and Tertiary - 10 Cultural Resource Review of the Proposed Greeley Discharge Pipeline, Weld County, Colorado aged sedimentary rocks (Tweto 1979). Deposition is largely alluvial and aeolian, with some residual sediments present. The upland plains are prime farmland when irrigated (Natural Resources Conservation Service 2018), and the major factor affecting the preservation of buried archaeological material is the agricultural and urban development in the area. Other disturbances in the area include oil and gas wells and associated pipelines and roads. In the cultivated uplands, a mantle of soil may have buried archaeological deposits, but cultivation has disturbed the upper soil horizons. Depositional settings favorable to the preservation of buried archaeological material are also commonly associated with floodplains and terraces. The northern end of the pipeline crosses one of these terraces, in a general area that has yielded both prehistoric camp sites and burials. These sites, however, are widely distributed, with a lower potential for any single pipeline trench disturbance to encounter buried cultural materials. Given this depositional setting and extensive cultivation, the project area is interpreted as having a moderate potential to contain significant buried archaeological deposits. SUMMARY AND RECOMMENDATIONS During the field reconnaissance, SWCA additionally identified three segments of two historic county roads (CR 42 and CR 47), one segment of a historic irrigation ditch (Gilmore Ditch), one newly identified bridge over the historic irrigation ditch, and one previously recorded bridge over the historic irrigation ditch (5WL3063). The desktop review revealed 148 known cultural resources that may be impacted by this project. These include 14 potential historic roads (Rs 34.5, 38, 40, 42,42,43,5, 44 and State Highway 256, 45, 46, 47, 48, 49, 50, 52, and 54), both recorded (n = 8) and unrecorded (n = 6) segments of six NRHP-eligible irrigation ditches (Gilmore Ditch, East Neres Canal, Morrison Seep Ditch, Lower Latham Outlet Ditch, Union Ditch, and Latham Ditch), one unrecorded segment of an irrigation ditch (West Neres Canal) that is not eligible for the NREP, six undocumented and unnamed ditch segments, one undocumented historic reservoir (Lower Latham Reservoir), one undocumented segment of an abandoned NM -IT -eligible railroad grade (Colorado Central Railroad/Union Pacific Railroad, La Salle to Julesburg Branch), one recorded abandoned railroad siding (Auburn Siding) that is not eligible for the NREP, one supporting segment of an NRHP-eligible transmission line (Kiowa Creek to Weld Transmission Line), one residence (Vetting House) that is not eligible for the NRITP, one historic trash dump (5WL883) that is not eligible for the NRHP, one prehistoric open camp (SWLSO) that is not eligible for the I` TRI P, one prehistoric open camp of unknown ' eligibility (5 L902), one prehistoric burial of unknown eligibility (5WL52), three undocumented schools (Auburn School, Beebe Draw School, and Sky View School), three undocumented inhles, one undocumented cemetery, and 103 undocumented farmsteads in the review area. Considering the disturbed nature of the landscape from oil and gas and modem development and the temporary nature of the disturbance associated with pipeline construction, the project would have no adverse indirect impact on the surrounding farmsteads, railroad grade, irrigation ditches and reservoir, transmission line, or other resources within 1 mile of the proposed centerline. SWCA recommends using boring to avoid physical damage to the historic Gilmore Ditch and the historic Colorado Central Railroad/Union Pacific Railroad grade and to prevent any potentially adverse impacts. Should development change and the Gilmore Ditch be open -cut rather than bored, SWCA recommends returning the segment to pre -construction conditions within 30 days of completion of any trenching, spanning, or boring to avoid any potential impacts as the ditch has not been formally evaluated for NRIIP eligibility for the current project. By adhering to these avoidance measures, construction and operation of the Greeley Discharge pipeline should result in no adverse effects to significant known historic properties. No areas within the review area possess a high potential for containing previously undocumented buried archaeological deposits, 11 Cultural Resource Review of the Proposed Greeley Discharge Pipeline, Weld County, Colorado although the northern end of the pipeline route crosses the Kersey Terrace, which has a moderate potential for containing previously undocumented buried archaeological deposits. However, in the event that such a discovery is made, SWCA recommends that a permitted archaeologist formally record and evaluate the resource for NRIIP eligibility. 12 Cultural Resource Review of the Proposed Greeley Discharge Pipeline, Weld County, Colorado REFERENCES CITED Autobee, Robert, and Deborah Dobson -Brown 2003 Colorado State Roads and Highways Multiple Property Listing.

An Emergency Event is an unexpected event, which, if not responded to immediately, has the potential to cause large-scale injury to humans and/or damage to the environment or property. An Emergency Event may include, but is not limited to: • Uncontrolled Fire, • Gas detected inside or near a building, • Extreme weather conditions (flooding, blizzard, hurricane, tornado), • Explosions (accidental or intentional, as in a bombing), Pipeline or equipment (vessels, etc.) rupture or serious leak, • Releases of hazardous chemicals (accidental or intentional), The nature of an Emergency Event will dictate the level of response and emergency actions necessary. Protection of human life and safety pre-empts the protection of the e nvironment or property. Incidents not considered an Emergency Event include: a Incidental releases of hazardous substances where no potential safety or health hazards exists, and where the substance can be absorbed, neutralized, or otherwise controlled by trained personnel in the immediate release area. • Small, quickly contained (incipient stage) fires • Other minor incidental events where there are no potential safety or health hazards. Post -Emergency Response includes activities performed after the immediate threat of an e mergency is stabilized or eliminated. Activities such as repairs, decontamination, and cleanup of the site are considered post -Emergency Response. These are not considered a part of the Emergency Response, so long as there is no further emergency condition or immediate threat of an emergency condition. 2.0 RECOGNITION, REPORTING AND NOTIFICATION 2.1 Recognition, Reporting and Notification -- 2.1.1 Upon recognition of an Emergency Event, authorized persons must activate local alarms and/or warning devices. Press ESD; Sound the emergency siren if applicable. If off -site assistance is required, immediately call 911. When requesting emergency service via 911 (or otherwise), emergency responders are to be advised of the "physical address" of where we expect them to respond. Give basic directions. The activities of 2,'1.1 through 2.1.3 may occur simultaneously, depending on the exigency of the situation. 10.00.70.02 Revision 01 Page 2 of 18 Effective Date 12/14/2017 -r t Williams.

These include noxious, invasive, and pest species (Adams County 2015, USFWS 2013, Weld County Government 2019). Weeds are easily spread through seeds or other regenerative plant parts and are notoriously successful generalists in a variety of macro and micro ecosystems (Petit and Fried 2012, USFWS 2013). The spread of weeds can be attributed to numerous avenues, including construction. Construction projects arc known to increase infestation by creating areas of disturbed ground where weeds thrive through movement of contaminated equipment and vehicles, and by increasing access for contaminated people and animals across uncontaminated lands (USFWS 2013). The pervasiveness of weeds across the United States and their deleterious effects on resources has encouraged government regulation as well as construction weed -control practices. Rocky Mountain Midstream (RMM) is developing natural gas pipeline projects throughout northeastern Colorado and in Weld County. The pipeline projects typically require trenching or boring and include supporting pipeline infrastructure. Development often includes access roads, bore pull back areas, and additional work spaces as needed. RMM will typically seek a 50 -foot permanent rights -of -way (ROW.) with an additional 30 -foot temporary construction ROW for construction access. Pipelines and the associated infrastructure have been designed to minimize new disturbance by placement adjacent to roadways and other existing linear utility ROWs. RMM is committed to eliminating the introduction of weeds and preventing the spread of weeds along pipeline ROWs within Weld County and other Colorado counties. In order to minimize noxious and other weeds regulated by the Colorado Noxious Weed Act of 1990 supported by the Weld County Weed Division Tasks and Platte Invasives Endeavor (PIE) Plan of 2008, this Weld County Weed Management Plan (WMP) provides general ' I formation and documents the process used to identify, assess, and minimize the spread of noxious and other weeds before, during, and after pipeline installation. DESIGNATED WEED SPECIES The State of Colorado lists 78 noxious and/or invasive weed plant species (State of Colorado 2018). Colorado weed species, including those in Weld County, are separated by pervasiveness near the bottom of this WMP. • Colorado statewide List A species are designated by the Commissioner for eradication. There are 25 List A species. • Colorado statewide List B weed species arc species for which the Commissioner, in consultation with the state noxious weed advisory committee, local governments, and other interested parties, develops and implements state noxious weed management plans designed to stop the continued spread of these species. There are 37 List B species. I Rocky Mountain Midstream Weld County Weed Management Plan • Colorado statewide List C weed species are species for which the Commissioner, in consultation with the state noxious weed advisory committee, local governments, and other interested parties, will develop and implement state noxious weed management plans designed to support the efforts of local governing bodies to facilitate more effective integrated weed management on private d public lands. The goal of such plans will not be to stop the continued spread of these species but to provide additional education, research, and biological control resources to jurisdictions that choose to require management of List C species. There arc 16 List C species. WELD COUNTY NOXIOUS WEEDS Weld County Weed Division is tasked to educate the public, mow and spray, and ensure that all landowners in Weld County control the designated noxious weeds on their property. Weld County weed species designated as noxious are; Absinth wormwood (Artemisia ahLsinthium), black henbane (Hyoscywnus niger), bull thistle (Girsiwn vul are), Chinese clematis (Clematis orientalis), common mullein (Verbascwn thapsius), dalmation toadflax (Linaria spp,), dames rocket Wesperis rnatronalis), houdstongue (Cynoglossum of fi`cinale), leafy spurge (Euphorbia esula), musk thistle (Carduus nutans), myrtle spurge (Eu phorbia myrsinites), Russian knapweed (Acroptilon repens), Scotch thistle (On oordiwwn acanthium), and yellow nutsedge (Cyperus esculentus; Weld County 2019). INVASIVE WEED SPECIES PLANNING, PREVENTION, AND MONITORING The Weld County Weed Management Team (WIVET will be consulted during the planning phase of the pipeline prior to construction. This consultation will help to inform RMM of best management practices for weed planning, spread prevention, and monitoring. In addition to measures reco • ended by the Weld County WMT, prior to construction, RMM will complete the following tasks. • Educate and train contractor personnel on weed occurrence, identification, infestation pa I ways, and mitigation. • Design a site footprint avoiding unnecessary soil disturbance where possible. • Use methods that prevent weed colonization by minimizing exposure to seed dispersal vectors and susceptibility to infestation during on -site inspection. • Conduct soil and vegetation assessments. • Treat all noxious weeds and invasive species. • Dispose of contaminated objects according to recommendations by the WMT. In addition to measures recommended by the Weld County WMT, during to construction, RMM will do the following. • Post weed awareness messages at strategic locations so that they are visible to all workers. • Minimize soil disturbance where possible. • Prevent weed germination and establishment by retaining native vegetation around the site. • Locate and use weed -free staging areas. 2 Rocky Mountain Midstream Weld County Weed Management Plan • Ensure equipment remains free of noxious weed seeds/propagules when entering the construction area or moving between locations of known infestation by avoiding these locations and/or regularly washing/brushing down equipment. • Accept only certified 'weed -free' materials and inspect seed, straw, mulch (including wattles, straw bales, dams, etc.), and gravel. • Maintain topsoil stockpiles in a weed -free condition through treatment and use of sterile and/or desired native cover crops. • Treat all noxious weeds and invasive species. • Dispose of contaminated objects according to recommendations by the WIVE In addition to measures recommended by the Weld County WMT, post -construction, RIVIM will do the following. • Treat all noxious weeds and invasive species. • Dispose of contaminated objects according to recommendations by the wMT. • Revegetate with a diversity of native grasses and simple forts. Seed mixtures used will be prescribed by the surface landowner and/or at the recommendation of the Weld County WMT. • Maintain topsoil stockpiles in a weed -free condition through treatment and use of sterile and/or desired native cover crops. • Accept only certified `weed -free' materials and inspect seed, straw, mulch (including wattles, straw bales, dams, etc.), and gravel. • Incorporate field -wide vegetation monitoring by trained, knowledgeable personnel. • Monitor disturbed areas annually. • Conduct ' onitoring in late spring to assess new germination and allow for immediate response. Determine a plan of action based on evaluation status. • Document species and size of infestations. INVASIVE WEED SPECIES CONTROL ACTIONS Noxious weeds and invasive non -desirable species will be controlled along all pipelines and associated project areas. Vegetation monitoring by trained personnel (:detection and analysis) during all project phases and pre -construction consultation with the Weld County WMT will dictate the control measures required for the project. Control actions under consideration include the following. • Spraying activities — Chemical selection will be based on documented success of specific species and recommendation by the W _MT. All chemicals will be applied according to label directions to ensure environmental safety, chemical efficacy, and cost-effective treatment. Spraying will start in late spring after target weeds are large enough and temperatures are conducive for effective control herbicide uptake and continue until all project locations are effectively treated. Treated sites will be monitored for effectiveness and reapplication administered where and when required based on monitoring reports. Completion of treatment is expected by late summer prior to onset of viable plant seeding. • Bare ground application - Bare ground will be maintained around equipment and facilities to control weeds and prevent fire hazards. All chemicals will be applied according to label directions 3 Rocky Mountain Midstream Weld County Weed Management Plan to ensure environmental safety, chemical efficacy, and cost-effectiveness. Bare ground control measures will begin in early spring after snow melt and continue until all sites arc effectively treated, no later than late spring.
