Address of the applicant and general office. PSCo 1123 West 3rd Ave., Denver, CO 80223 C. Summary statement of the project, to include when applicable: 1. Source, capacity, size, destination and type of facilities, support STRUCTURES, lines, etc., involved. PSCo is proposing to construct and operate the Lancaster to Fort Lupton Natural Gas Pipeline Project (Project) in Weld County, Colorado. The proposed Project would reinforce the natural gas system infrastructure and provide improved and reliable service to future and existing customers in the region. The proposed Project is needed to meet the increased demand for natural gas services as a result of the recent population growth and urban development. The proposed Project would transport natural gas from the existing Kerr- McGee Gathering, LLC Lancaster Gathering Facility, located on the south side of County Road (CR) 22, between CRs 31 and 37, to the existing PSCo-owned Fort Lupton Metering Station, located on the south side Barley Avenue, approximately 0.33 mile east of CR 31 (Exhibit A, Figures 1 and 2). The components of the proposed Project are described below. Exhibit A includes the detailed Project easement and right-of-way (ROW) drawings. 2. A detailed report shall be submitted which includes information on the following items: a. A description of the PIPELINE. Pipeline The length of the new 24 -inch high-pressure steel pipeline would be approximately 4.1 miles. The pipeline would be buried underground using open trenching techniques. In some locations, the pipeline would be constructed using horizontal directional drilling (HDD) techniques to bore under roads. The bore areas would be located outside of the roadway ROW. The pipeline would be designed with a maximum allowable operating pressure (MAOP) of 1,000 pound -force per square inch gauge. The pipeline would be buried at a 1 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines depth necessary to ensure a minimum 48 -inch cover over the natural gas pipeline once backfilling has been completed. Regulator Station The proposed Project would include construction of a new regulator station located within the Kerr-McGee Gathering, LLC Lancaster Gathering Facility property. Kerr-McGee Gathering, LLC is a subsidiary of Anadarko Petroleum Corporation. In some locations of this permit application, the Kerr-McGee Gathering, LLC Lancaster Gathering Facility is referred to as the Anadarko Lancaster Gathering Facility. The proposed regulator station would be located immediately south of the existing electrical substation owned by United Power Incorporated and west of the agricultural and oil and gas production parcel owned by Robert Warner (Exhibit B). The regulator station would include aboveground pipeline and associated valves, a pig launcher (used to insert remote cleaning and inspecting devices used for cleaning and inspecting into the pipeline), and four buildings to house components of the regulator station. The buildings include a remote terminal unit/gas chromatograph (RTU/GC) building approximately 128 square feet in size, one metering building approximately 200 square feet in size, and two control valve buildings approximately 200 square feet in size. One temporary access road running south from CR 22 would be required for access to the proposed regulator station (Exhibit B). The access road would use an existing access off CR 22 that is currently used for the United Power Incorporated substation and run parallel to and just west of the eastern property boundary of the Kerr-McGee Gathering, LLC Lancaster Gathering Facility. Up to three additional buildings would be built at a future date and are not part of the scope of this Project. They include one metering building approximately 200 square feet in size and two control buildings, each approximately 200 square feet in size. The site plan for the proposed regulator station is included in Exhibit B. Existing Fort Lupton Metering Station The existing PSCo-owned Fort Lupton Metering Station was constructed as part of PSCo's Cherokee Natural Gas Pipeline Project in 2014. The proposed Project would tie into the Cherokee natural gas pipeline at the existing Fort Lupton Metering Station. Besides the interconnection of the proposed pipeline, up to two new buildings, each approximately 100 square feet in size would be added to the existing metering station property as part of the proposed Project. The buildings would be used to protect pipeline equipment. Temporary Use Areas: The proposed Project would require the use of four temporary use areas (TUAs) (total area of 18.69 acres) to be located along the natural gas pipeline alignment in unincorporated Weld County as shown in pink in Exhibit A, Figures 1 and 2. Two of the TUAs would be used when the county road are bored under. These TUAs would be used for delivering the boring equipment and natural gas pipe, excavating boring entry and receiving pits, temporarily stockpiling excavated soil from the pits, and laydown for natural gas pipe segments. The boring pits would be backfilled, compacted, and restored and revegetated upon completion of the pipe installation as described Questions 6 and 7 of this Use by Special Review (USR) application. The other two TUAs would be used for storing 2 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines construction equipment and supplies during construction. Following construction, these areas would be returned to preconstruction conditions. Project Design, Construction, and Operation The proposed Project would be designed, constructed, and operated to meet or exceed federal and state standards and safety requirements applicable to the proposed facilities. The entire length of the proposed natural gas pipeline would be designed and constructed to meet the requirements of the U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration, Part 192 —Transportation of Natural and Other Gas by Pipeline: Minimum Federal Safety Standards (49 [Code of Federal Regulations] CFR 192). Safety measures would include continuous telemetered monitoring of the natural gas pipeline and all facility operations by PSCo's manned Gas Control Center. During natural gas pipeline installation, PSCo would install a corrosion prevention system designed to eliminate metal loss during the life of the natural gas pipeline, and a third party would x-ray all pipe welds to verify their integrity prior to the pipe being placed into operation. Additional natural gas pipeline safety measures are described in PSCo's Gas Emergency Plan. Before the natural gas pipeline is put into service, it would undergo hydrostatic pressure testing during which it would be filled with water and tested at a pressure 1.5 times the design MAOP to verify the structural integrity of the pipeline. A baseline in -line inspection (ILI) of the entire natural gas pipeline would also be conducted as a reference for future ILI runs to be conducted as part of PSCo's ongoing Integrity Management Program. After being put into service, the natural gas pipeline would be patrolled on annual, semi- annual, and quarterly intervals to check for leaks and cathodic protection levels. Inspection intervals will adhere to requirements set forth in the U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration, Part 192. Construction activities would be conducted in accordance with all applicable regulations. Major activities involved in construction of the proposed Project would include staging materials, establishing material laydown areas, natural gas pipeline trenching and use of HDD at roadway crossings, natural gas pipeline installation and welding, pressure -testing, backfilling the natural gas pipeline trench, and re -grading and re -paving any affected private roads according to landowner agreements. Two material staging and laydown areas would be established, one on the existing Fort Lupton Metering Station parcel, and one at the proposed regulator station. Additional staging of materials would occur within the temporary construction easement and TUAs. No other laydown or staging areas would be required. Construction activities would be sequenced and scheduled to minimize the length of open trench areas. The natural gas pipeline trench would be approximately 48 inches wide and 84 inches deep. Trenching involves excavating a trench for the pipe and is typically accomplished using a crawler -mounted wheel -type or rubber -tired wheel -type ditch digging machine or track -type excavators. Areas that show signs of unstable soil conditions or require larger excavations would be excavated using a trackhoe or backhoe. The trench would be at 3 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines a depth necessary to ensure a minimum 48 -inch cover over the natural gas pipeline once backfilling has been completed. Surface disturbance generally would be limited to a work zone width of 100 feet. This work zone includes a 50 -foot -wide permanent pipeline easement, along with an additional 50 -foot - wide temporary pipeline construction easement, a permanent 100 -foot by 250 -foot easement for the proposed regulator station, and a permanent access easement for the proposed regulator station. All easements for the proposed Project are being acquired through agreements with landowners. For the purposes of this application, the 50 -foot -wide permanent easement, along with the additional 50 -foot -wide temporary construction easement, regulator station, and one permanent access road for the regulator station, is referred to as the proposed Project ROW. b. A description of the preferred route or site and reasons for its selection. Routing Analysis A routing analysis was performed for the proposed Project to define a pipeline route that would avoid and minimize impacts to the natural and developed environment to the extent practicable. A routing report detailing the findings of the analysis, along with resource maps depicting resources in the vicinity of the proposed Project, and alternative routes considered, is included as Exhibit C The subsequent paragraphs describe the preferred route and reasons for its selection. Preferred Route The preferred route (Figures 1 and 2) runs south from the eastern side of the existing Kerr- McGee Gathering, LLC Lancaster Gathering Facility on the east side of an existing Tri-State Generation and Transmission, Inc. (Tri-State) electric easement for approximately 3 miles to Barley Avenue. This portion of the route crosses land used for agriculture and oil and gas production. The route avoids an oil and gas facility south of the CR 20 crossing by veering slightly east and back south of the road. The route also veers eastward in several areas south of CR 18, to avoid oil and gas pipeline easements and facilities. The route is primarily located on the east side of an existing Tri-State easement as it continues south across agricultural land to the intersection with Barley Avenue. The route intersects Barley Avenue about 0.2 mile east of Grant Street. A water storage facility is planned on the Fort Lupton parcel south of Barley Avenue. In addition, the route crosses the proposed Tri-State electric easement approximately 0.1 mile north of Barley Avenue to avoid that Fort Lupton parcel. The route continues south/southwest across Barley Avenue for about 0.25 mile and then runs west, avoiding oil and gas facilities within agricultural land for 0.6 mile, along an existing PSCo pipeline easement. The route then turns north for approximately 150 feet and then heads runs west to intersect the existing PSCo Fort Lupton Metering Station connection point. The route south of Barley Avenue is located within land used for agriculture and oil and gas production. Numerous oil and gas facilities are present in the area, including tanks, wells, and pipeline facilities. Land ownership 4 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines along the preferred route is private, with the exception of Weld County and Fort Lupton road ROWs. The route is preferred because it constitutes a least -distance option between the Kerr-McGee Gathering, LLC Lancaster Gathering Facility and the Fort Lupton Metering Station while avoiding the Aristocrat Ranchettes subdivision and existing and proposed utility line corridors. This route is preferred because it would have the least impacts to residential areas, congested streets, roadway ROW, and farmland. The preferred route would take advantage of an existing electric transmission line and pipeline corridor to avoid potential impacts to previously undeveloped areas. Additionally, sufficient space appears to be available for minor route adjustments if they are needed during the Weld County and Fort Lupton ROW permitting process. Access to the preferred route would be from CR 22, CR 20, CR 18, and Barley Avenue. The only permanent access would be off CR 22 to use an existing access to the proposed regulator station. Amy Joseph with Weld County Public Works stated that the only access permit application required for this USR permit application would be for use of the existing permanent access off CR 22.1 The access permit application is included as Exhibit D. The pipeline would be bored at the intersection with county roads. Preferred Route Alternative Segments Two preferred route alternative segments were considered to provide flexibility in further route refinement. The preferred route alternative segments are shown in orange on Figure 2. One preferred route alternative segment is located on the north side of Barley Avenue where the preferred route would cross the Tri-State easement for a proposed electric transmission line. This segment would allow the pipeline to cross the Tri-State easement at a right angle if required by agreements with Tri-State. It should be noted that alternating current (AC) mitigation would be installed with the pipeline at the Tri-State crossing to ensure the safety of the pipeline when it is located in close proximity of the proposed electric line. AC mitigation would protect the line from negative effects by dissipating any capacitive, inductive, or conductive electrical current from the transmission line using grounding techniques. One other preferred route alternative segment runs parallel to the preferred route on the south side of Barley Avenue. This preferred route alternative segment allows greater flexibility for routing in close proximity of several utility lines in the vicinity of the preferred route. c. Procedures to be employed in mitigating any adverse impacts of the proposed routes or sites. PSCo would mitigate adverse impacts to the natural and developed environment during the design, construction, and operations phases of the proposed Project, as described below. Joseph, A. 2017. Communication between Amy Joseph, Weld County Public Works, and John Heule, Tetra Tech Inc., concerning Public Works permits required for construction. Phone Conversation on February 1, 2017. 5 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines Air Quality Impacts to air quality in the Project area would be short term, transient, and limited to the construction period of approximately 4 months. Construction vehicles and equipment required for vegetation clearing, trenching, boring, and re -contouring may produce fugitive dust or exhaust emissions during the construction phase of the proposed Project. Dust suppression would be conducted during construction. Water for dust suppression would be obtained from municipal sources. No direct emissions are expected during the operation of the proposed Project. Emissions would be produced by end -users combusting the natural gas, and natural gas combustion produces the lowest air emissions of ozone precursors and particulate matter when compared to combustion of other fossil fuels. Small fugitive emissions of methane, a greenhouse gas, and other natural gas hydrocarbons from pipeline components such as valve sets and fittings would occur during the operation of the pipeline. These emissions would be regularly monitored and would be in conformance with all federal and state laws. Accordingly, mitigation for fugitive emissions is not necessary in relation to the proposed Project. Visual Quality Construction of the pipeline would pose some short-term visual effects including the sight of equipment, construction crews, and staging areas. Visual effects would be temporary, because the pipeline would be installed underground and equipment and staging areas would be removed once construction has been completed. Following construction, the pipeline temporary and permanent easements would be restored to preconstruction conditions and appearance. Long term visual effects during operation of the proposed Project would be limited to aboveground components. The new aboveground components of the Project would be located on the proposed regulator station parcel and at the existing Fort Lupton site south of Barley Avenue. These components would be observed in the context of the existing Kerr- McGee Gathering, LLC Lancaster Gathering Facility, the United Power Incorporated substation, and existing Fort Lupton site and would appear as an extension of the existing facilities. Buildings would be in conformance with all Weld County building requirements. Therefore, mitigation for visual effects is not necessary in relation to the aboveground features of the proposed Project. Ground Cover and Vegetation, or Other Natural Features The proposed Project would be predominantly located within and adjacent to other transmission corridors, roadways, and areas of developed industrial and commercial land use. The natural gas pipeline would be installed in a trench or by boring and ultimately be buried underground. The proposed aboveground facilities would be located at the proposed regulator station at the north end of the proposed Project, adjacent to the existing Kerr- McGee Gathering, LLC Lancaster Gathering Facility as well as on the south end at the 6 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines existing Fort Lupton facility. Existing ground cover in the proposed Project corridor primarily consists of grassland previously disturbed by construction of pipelines, transmission lines, and other development. Prior to construction, staking would occur to delineate limits of disturbance for the Project and other Project features. Staking would be used to mark and avoid impacts to sensitive features. Staking would be maintained throughout construction and a survey team would be available to replace any staking that has been disturbed. Upon completion of construction, the pipeline temporary and construction easements would be restored to preconstruction conditions. The proposed regulator station and existing access road would remain for the life of the Project. Construction materials and debris would be removed from the site. Work areas would be re -contoured, as required, so that surfaces would drain naturally, blend with the natural terrain, and be left in a condition that would facilitate natural revegetation. Disturbed areas where vegetation was removed by construction activities to an extent that it caused potential soil erosion would be treated with seedbed preparation techniques, re -seeded with an approved seed mixture, and mulched, if necessary, during the planting season. Further discussion regarding mitigation measures for weed management and revegetation are provided in Exhibit E. Water Quality Surface water features and wetlands A wetland and other waters of the U.S. (WoUS) delineation, including a desktop analysis and field survey, was completed as part of the biological resources assessment. The delineation revealed one potential WoUS in the vicinity of the Project. Impacts to the wetland would be avoided to the extent practicable. If construction within the wetland is necessary, PSCo would comply with all federal and state regulations. Potential surface water features and wetlands and WoUS are shown on maps included in the Biological Resources Report (Exhibit F). Stormwater PSCo would comply with all federal, state, and local water quality construction requirements and obtain all necessary state and county stormwater and water quality permitting. During construction of the proposed Project, stormwater would be managed through implementation of a state -approved Stormwater Management Plan (SWMP) and a county -approved Erosion and Sediment Control Plan and Stormwater Quality Permit to control for runoff and sediment loading through implementation of best management practices (BMPs) as further discussed and presented in Table 1. The proposed Project is not located in an area subject to Weld County Municipal Separate Storm Sewer Systems (MS4s) requirements. A summary of BM Ps to protect water resources from potential contamination is provided in Table 1. 7 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines Table 1: Summary of BMPs for Protection of Water Resources Potential Pollutant Source Activities Associated With This Pollution Source and BMPs Selected To Control The Source Management of contaminated soils No known contaminated soils exist within the Project ROW. If contaminated soils are encountered, all activity would be stopped until the situation can be assessed. The designated environmental project officer would be contacted for further direction. Loading and unloading operations Activities associated with this pollution source are potential spills during delivery and unloading of materials at the staging areas during all phases of construction activity. BMPs 1. Loading and unloading operations would occur within the disturbance limits at stablized material storage and staging areas. 2. Administrative controls may include materials management practices, personnel training, providing spill kts where needed, minimizing the number of areas where loading and unloading occur. Outdoor storage activities (including building materials, fertilizers, chemicals, etc.) Activities associated with this pollution source are storage of material at the staging areas and the potential for spills and leaks from these materials. BMPs 1. Containment of the storage or staging areas may include Installation of silt fence, erosion/sediment control logs, temporary berms, etc. Use of secondary containment devices for storage of Iiqulds and petroleum products may also be necessary. 2. Administrative controls may include materials management practices, personnel training, providing spill kts where needed. Vehicle and equipment maintenance and fueling Activities associated with this pollution source are fueling of equipment or vehicles and equipment repair and they may occur during all phases of construction activity. BMPs 1. Limit areas where fueling occurs and equipment maintenance activities at the site Stage fueling /maintenance activities away from storm sewer system inlets/waterways. Provide spill kits where fueling is conducted. Use plastic sheeting, drip pans, dirt berms, and other measures to contain fluids. Clean up and dispose of material spilled immediately. 2. Administrative controls may include materials management practices and personnel training. 3. The contractor is responsible for preparing a spill control and secondary containment plan for fuel storage areas. Routine maintenance activities involving fertilizers, pesticides, detergents, fuels, solvents, oils, etc. Activities associated with this pollution source are limited given the short-term nature of utility Installation activities, Fueling and maintenance activities involving vehicles and equipment and the potential for use of fuels, oils, solvents, etc. are discussed above Seeding operations typically occur during the final phase of the proposed Project and may involve use of fertilizers and tacklfers, as needed. Fertilizers are typically brought to the site by a seeding contractor during seeding operations and any remaining material is removed from the site by the contractor. BMPs 1. Liquids should be stored in secondary containment. Administrative controls may include materials management practices and personnel training In proper use and storage of mater als. 8 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines Table 1: Summary of BMPs for Protection of Water Resources Potential Pollutant Source Activities Associated With This Pollution Source and BMPs Selected To Control The Source On -site waste management practices (waste piles, liquid wastes, dumpsters, etc.) Activities associated with this pollution source are generation of waste materials during all phases of construction activities that include but are not limited to debris, saw cutting water, waste asphalt or concrete generated during excavating In paved areas, and wastes generated from various activities such as pipe and joint cleaning and sealing. BMPs 1. Use of waste receptacles, vacuuming up saw -cutting water, waste asphalt, and concrete should be hauled off immediately or be contained by either covering with a tarp or by temporary berms, silt fence, sedimentferosion control log, etc. Liquids should be stored In secondary containment. 2. Use of one dumpster for ferrous material and construction material recycling and another bear -proof dumpster for garbage. 3. Utilize portable waste facilities (toilets) at the construction site. Concrete truck/equipment washing, including the concrete truck chute and associated fxtures and equipment Activities associated with this pollution source are concrete pours that include, but are not limited to, restoring paved areas for final stablization, pouring transmission pole foundations, concrete vaults, or transformer pads. BMPs 1. Dedicated concrete washout areas that are clearly marked and maintained, Where applicable, urban mobile concrete washout structures or kiddy pools can be used depending on the amount of concrete used on the proposed Project Dedicated asphalt and concrete batch plants No dedicated asphalt or concrete batch plants are planned for this site, Non-industral waste sources worker trash and portable toilets Activities associated with this potent al pollutant source include the generation of non- industrial waste such as discarded building materials, litter, and sanitary waste at the construct on site that may cause adverse Impacts to water quality. BMPs 1. Good housekeeping practices and trash collected In vehicles and disposed of off - site or the use of waste containers. Portable toilets should be properly anchored down and located away from the storm sewer system or waterways. Other areas or procedures where potential spills can occur Other potential pollution source identified is the generation of condensates during flushing or abandonment of existing gas Imes in the area. PSCo has established procedures for the collection and disposal of condensate material at all projects Bentonite associated with boring activities would be present as a potential pollutant on site, The BMP selected to control this source involves using a designated containment pit and/or a vacuum truck for removal of bentonite from the site and site management practices Groundwater Quality and Quantity The proposed Project would not use groundwater or directly contribute to groundwater recharge or impact aquifer water levels. Groundwater quality also would be protected through the implementation of a SWMP and through the implementation of waste management BMPs during construction (presented in Table 1). Existing wells, including water wells, would not be impacted by construction or operations of the proposed Project. Areas of the pipeline that would be bored (to avoid impacts to county roads) have the potential to encounter groundwater. It is also possible to encounter groundwater during normal trenching activities, 9 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines but less likely. Prior to construction, these areas would be investigated to determine the depth to groundwater. If necessary, a Construction Dewatering Permit would be obtained from Colorado Department of Public Health and Environment (CDPHE) prior to the initiation of such activities. Terrestrial and Aquatic Animals and Habitat A desktop analysis and a preliminary field reconnaissance were performed to identify wildlife habitat in the area of the proposed Project (see Exhibit F). No federally listed species were observed to have suitable habitat in the Project ROW. The only state threatened or endangered species determined to have suitable habitat within the Project ROW was the burrowing owl (see discussion below). Six state species of concern were identified to have suitable habitat in grasslands within the Project ROW including the ferruginous hawk, mountain plover, swift fox, black -tailed prairie dog, northern pocket gopher, and the common garter snake. Other species that do not have regulatory protection may be temporarily displaced during construction, but these species would not be prohibited from returning to the site once the construction period has ceased. Burrowing Owls. The proposed Project ROW was observed to intersect two prairie dog colonies during the biological resources assessment survey (Exhibit F). Burrowing owls are known to utilize prairie dog colonies for habitat, and are known to occur in Weld County. Burrowing owls are listed as state threatened. Burrowing owl surveys are planned prior to construction in the summer of 2017 in accordance with Colorado Parks and Wildlife (CPW) protocol. If burrowing owls are observed in the vicinity of the Project, consultation with CPW would be completed, and recommended seasonal buffers for the species would be adhered to. Consultation with the U.S. Fish and Wildlife Service and CPW was initiated in February 8, 2017, requesting concurrence with the findings reported in Exhibit F. A copy of this correspondence is provided in Exhibit F. All migratory birds within the Project ROW would be protected against take under the Migratory Bird Treaty Act. Noxious Weeds. Table 2 lists the noxious weeds identified during the field reconnaissance. The noxious weeds were identified based on the Colorado Noxious Weed Act (35-5.5 CRS [Colorado Revised Statutes]). Weed species were present throughout the Project area, particularly in recently disturbed areas, near roadways and railways, and in fallow fields. No List A species were identified in the Project area; one List B species and four List C noxious weeds were identified. No large infestations of noxious weeds were identified. 10 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines Table 2: Noxious Weed Species Observed during Field Surveys Weed List (A, B, or C)1 Common Name Scientific Name State Management Policy List A Weeds None observed List B Weeds Scotch thistle Onopordum acanthium Follow Weld County Weed Management Plan for Treatment and Control (Spray Tordon® prior to construction disturbance If present Immediately prior to constructor) List C Weeds Common Mullein Verbascum thapsus Control up to landowners' discretion Field bindweed Convolvulus arvens!s Control up to landowners' discretion Downy brome Bromus tectorum Control up to landowners' discretion Puncture vine Tribulus ferresfris Control up to landowners' discretion Redstem filaree Erodium cfcufarfum Control up to landowners' discretion Tetra Tech consulted with Tina Booton, Weld County weed supervisor, in regards to the treatment of noxious weeds for the Project. Ms. Booton recommended that broadleaf weeds be treated by the herbicide Tordon. (Tina Booton 2017).2 More information regarding measures that would be used to mitigate noxious weeds for the Project can be found in Exhibit E. Soils, Geologic Conditions, and Natural Hazards The proposed Project would be primarily constructed underground and would not affect soil and geologic conditions in the area, impact any streambed meander limits, or affect aquifer recharge. Therefore, mitigation for these resources is not necessary in relation to the proposed Project. A map of soil types crossed by the Project is included in Exhibit C. Nuisances Noise, Glare, Dust, Fumes, Vibration, and Odor Levels Natural gas pipelines are common throughout Colorado's Front Range and are compatible with a wide variety of land uses, including residential, commercial, industrial, and agricultural uses. If a nuisance arises during construction, the nuisance would be mitigated in coordination with Weld County. Short-term localized impacts are anticipated from a temporary increase in traffic, construction equipment exhaust (fumes), and clearing and preparing areas for construction. The short- term impacts are not expected to result in nuisance effects. Noise. Construction work hours would be 7 AM to 7 PM Monday through Saturday unless otherwise specified by Weld County. Construction may occur on Sundays and other hours 2 Booton, T. 2017. Communication between Tina Booton, Weld County Weed Supervisor, and John Heule, Tetra Tech Inc., concerning the noxious weeds actively managed by Weld County. Phone Conversation on January 4, 2017. 11 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines outside the 7 AM to 7 PM timeframe on an as -required basis. If unforeseen circumstances occur, or construction is delayed, PSCo may require construction outside the 7 AM to 7 PM timeframe to complete construction. Construction would occur in one shift. Construction of the proposed Project would be in conformance with all Weld County noise standards (Weld County Code 14-9-10 et seq.) as established in Section 25-12-101, CRS. The following mitigation measures would reduce the potential for temporary adverse noise impacts during construction: • Implementing a complaint resolution program whereby residents can contact PSCo directly with their noise concerns. Throughout construction and operation of the proposed Project, PSCo would document, investigate, and attempt to resolve legitimate Project - related noise complaints. • Notifying landowners who may be directly impacted along the proposed Project ROW prior to noisy construction activities. • Coordinating construction vehicle travel to reduce the number of passes by sensitive receptors. • Restricting noisy construction activity, which causes off -site annoyance as evidenced by the filing of a legitimate noise complaint, would be restricted to daytime hours (i.e., 7 AM to 7 PM) unless construction during nighttime hours is requested by PSCo. • Using equipment with sound -control devices no less effective than those provided on the original equipment. • Fitting all internal combustion engines with appropriate muffler systems. Dust. Dust would be generated during all construction phases with the exception of pressure testing. Dust suppression would be conducted during construction. Water for dust suppression would be obtained from municipal sources. No air quality modeling has been completed for the proposed Project. Based on the amount of the temporary disturbance area, PSCo is obtaining a General Construction Permit from CDPHE, and preparing a Fugitive Dust Plan and Air Pollutant Emission Notice (APEN). The Fugitive Dust Plan would be completed and the APEN would be obtained prior to construction. Construction vehicles and equipment would be shut off when not in use to limit the amount of exhaust emissions. Wind patterns common to the area would act as a dispersion mechanism for air pollutants Odors. Odors resulting from construction of the proposed Project may include vehicle and equipment exhaust and asphalt odors from repaving activities. These odor emissions are expected to be short-term and transient in nature, limited to the area of active construction, and adequately dispersed by diurnal winds. Mitigation for odors generated during construction is not necessary. During long-term maintenance of the proposed Project, mercaptan odors may be intermittently noticeable. Mercaptan is the chemical injected into the natural gas product that 12 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines produces a sulfurous ("rotten egg") odor as a safety measure as required by federal regulation. However, continuous odors are not expected and mitigation is not necessary. Mercaptan odorant is already stored at the existing Fort Lupton Metering Station in the permanent holding tanks. Mitigation for odors generated during operations is not necessary. Areas of Paleontological, Historic or Archaeological Importance A desktop Class I cultural resources survey was completed in January 2017 and is included as Exhibit G. The Class I did not identify any previously recorded cultural resources that would be intersected by the pipeline. Should any undiscovered paleontological, historic, or archaeological artifacts be uncovered during construction activities, such activities would be temporarily stopped until a qualified person can evaluate the object of interest. Health and Safety One of the greatest risks to buried natural gas pipelines is excavation from individuals unaware of the location of a natural gas pipeline (third -party damage). PSCo installs natural gas pipeline markers in the permanent pipeline easement, i.e., outside roadways, to identify that a natural gas pipeline is buried nearby. Markers identify the product carried in the natural gas pipeline such as natural gas, the name of the natural gas pipeline operator, and its 24 - hour emergency contact number and the area's one -call center number. The detailed design of the proposed Project would avoid existing utilities and the ROW and access permitting process would include coordination with the county including recordation of the pipeline location to avoid third -party damage. This process would reduce the probability that individuals would damage the pipe with ground -disturbing activities. Hazardous Materials and Waste Management Construction, operation, and maintenance activities would comply with applicable federal, state, and local laws and regulations regarding the use of hazardous substances. In its contract with the construction contractor, PSCo would specify that it would hold a required preconstruction meeting with the contractor to ensure that all applicable laws and PSCo's procedures would be followed. Hazardous chemicals that may be used during construction are those found in diesel fuel, gasoline, coolant (ethylene glycol), and lubricants in machinery. Hazardous materials would not be drained onto the ground or into streams or drainage areas. Enclosed containment would be provided for trash disposal. All construction waste, including trash and litter, garbage, other solid waste, petroleum products, and other potentially hazardous materials would be removed to a disposal facility authorized to accept such materials. In some instances, the contractor may require a fueling tank. The tank would typically hold approximately 500 gallons. The tank would meet Occupational Safety and Health Administration requirements for secondary containment. Construction activities would be performed by methods that prevent entrance or accidental spillage of solid matter, contaminants, debris, and other pollutants and wastes into flowing 13 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines streams or dry watercourses, lakes, and underground water sources. Construction components are arranged in a manner to preserve trees and vegetation. Excavated material or other construction materials would not be stockpiled or deposited near or on stream banks or other watercourse perimeters where they could be washed away by high water or storm runoff or could encroach upon stream banks. Fueling vehicles would be equipped with spill kits and fire extinguishers and personnel would be properly trained in spill prevention, control, and countermeasures. A Phase I environmental site assessment has been completed. No recorded environmental conditions have been identified in the Project ROW. Based on review of available information from federal and state databases, construction activities associated with the proposed Project are not anticipated to encounter known areas of soil or groundwater contamination. PSCo and its contractors would provide and maintain sanitary accommodations for the use of their employees during construction of the proposed Project in a manner that would comply with the requirements and regulations of health departments and of other governmental bodies. These accommodations, including trash dumpsters and portable waste facilities (toilets), would be located in several locations along the construction route based on the construction plan. Construction waste would be stockpiled in the construction staging areas and would be removed from the construction sites during the construction process. Two types of dumpsters would be used during construction: one for ferrous metal and construction material recycling and one for garbage. The proposed Project would not include the need for permanent dumpsters or sanitary facilities. Construction and operation and maintenance activities would follow BM Ps for the management of wastes to avoid and minimize impacts from potential spills or other releases to the environment. These practices are discussed in greater detail below. Adverse impacts from the release of construction or operations wastes are not expected. In general, if a trenching or boring activity uncovers previously unknown areas of contamination, work would immediately be stopped until an identified PSCo contact is notified and consulted. PSCo, or its contractor, would then perform all necessary testing and handling of such materials as required by applicable state and/or federal requirements. d. An outline of the planned construction, including startup and commissioning schedule, to include the number of stages and timing of each. An approximate construction sequencing schedule for the entire natural gas pipeline and proposed regulator station is as follows: • Boring and trenching of the pipeline beginning August 2017; expected completion: December 2017 14 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines • Construction of the proposed regulator station, including four buildings, gravel surface, 7 -foot security fence topped with a three -strand barbed wire outrigger, and construction of the access road all beginning September 2017; expected completion: December 2017 • Construction of the Fort Lupton Metering Station including up to two buildings beginning September 2017; expected completion: December 2017 • Hydrostatic testing: December 2017 • Commissioned and in-service: December 2017; possibly into first quarter 2018 • Reclamation activities including revegetation and grading ongoing throughout construction and completed September 2018 e. Information of any public meeting conducted, to include the location, date, time, attendance and method of advertising. Information regarding the public meeting held on January 26, 2017, including questions asked during the meeting, can be found in Exhibit H. f. A description of the hazards, if any, of fire, explosion and other dangers to the health, safety and welfare of employees and the general PUBLIC. Given the rural nature of the Project area in unincorporated Weld County, the hazards of fire, explosion, or other danger to the health, safety, and welfare of employees or the general public are minimal. PSCo has prepared a Gas Emergency Plan to establish emergency protocols for natural gas pipeline facilities that include the preparation and planning for emergencies and natural disasters, the receipt and classification of odor complaint and gas emergency calls, dispatch of company personnel, and responsibilities of response personnel. An emergency response plan would be developed for the construction and operations phases of the proposed Project. This plan would be written to include elements of the emergency response departments near the Project area, including how and when to communicate with the Weld County Sheriff's Office, the Weld County Paramedic Services, the Weld County Office of Emergency Management, and the Fort Lupton Fire Protection district. g. 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. PSCo has prepared a Plan to establish emergency protocols for natural gas pipeline facilities. The purpose of the Plan is primarily to minimize the hazard to the public, PSCo's employees, and to property; and secondarily to re-establish service should a service interruption occur. The Plan establishes procedures and defines responsibilities prior to, during and following an emergency; and includes contact information and instructions for all such anticipated 15 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines emergency situations. The Plan describes all specific responsibilities of PSCo responders, including dispatchers and emergency responders. PSCo gas control staff are responsible for the constant electronic monitoring (24 hours a day, 7 days a week) of gas system flows and pressures and for coordinating various sources of natural gas to ensure adequate system supply and pressure. When notified, they would immediately respond to pressure regulation or gas odorization problems. These problems may include, but are not limited to, distribution regulator failures, emergency valve operation, odorizer malfunctions, and reports of damage, accidents, fires, excessive noise or odor at the proposed regulator station or odorant injection facilities. Actions taken during a gas system emergency include, but are not limited to, maintaining the pressure integrity and supply of the gas distribution and/or transmission systems and contacting customers concerning emergency load reductions as needed. In an emergency situation, a natural gas pipeline pressure reduction or shutdown to minimize hazards to life or property may be necessary for numerous reasons, including a line break, a facility malfunction, fire or explosion, or an emergency situation resulting from an abnormal operating condition. In the case of a broken gas line or fire or explosion at or near a natural gas pipeline facility, a response might include the following activities: controlling pedestrian and vehicular traffic as necessary, requesting the assistance of local emergency responders/law enforcement personnel with this task if needed, and evacuating the site and/or nearby areas if needed. Emergencies involving a fire or an explosion located at or near a PSCo natural gas pipeline facility, considerable odorant leak or spill, or in the case of an outage resulting from the failure of equipment, a break of a gas main or any other reason, qualified PSCo personnel would be dispatched to control and/or correct the emergency situation. Planning for and safely restoring service to all facilities affected is the next step after proper corrective measures have been taken. Whether an outage is the result of a system emergency shutdown or a facility malfunction, the procedure to restore service is the same. The PSCo employee or unit responsible for emergency coordination must craft and implement a tactical plan to safely restore service. The following items (among others) would be considered when drafting a plan to restore service to the affected area: awareness of appropriate reporting requirements, dispatch of qualified personnel and notification of appropriate gas control and engineering units, and conduct of appropriate surveys, purging, and evaluation procedures, and establishment of an office command center as necessary. h. A description of the method or procedures to be employed to avoid or minimize the impacts on irrigated agricultural land. The proposed Project ROW is currently used as existing pipeline facilities, pastureland, county road ROW, ROW for other utilities, and for dryland farming. The proposed regulator station is not located within land currently used for farming, so it is not anticipated to have an impact on irrigated agricultural land. No dryland farming area would be permanently removed for the proposed Project, because land would be restored to its original condition or left fallow 16 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines according to landowner agreements. PSCo is working closely with landowners to identify routes that minimize impact to agricultural land and farming operations to the extent practicable. The natural gas pipeline temporary and permanent easements would be able to be farmed following construction. If disturbance to crops occurs, the landowner would be compensated at fair market value. In addition, construction disturbance would be minimized to the extent practicable to minimize impacts to resources within the ROW including agricultural land. Following construction, all disturbed areas would be reclaimed or revegetated according to procedures discussed in the Weed Management and Revegetation Plan (Exhibit E). Topsoil would be segregated from subsoil during excavation and replaced on top of subsoil following pipeline installation. This method would preserve the existing seed bank in the soils and expedite successful reclamation efforts following construction. i. 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. The Weld County Code, Chapter 22, Comprehensive Plan, has been reviewed and the proposed Project is consistent with the intent of the Comprehensive Plan, including Land Use, Environmental Resources, and Natural Resources as discussed in the subsequent paragraphs. The proposed Project is consistent with the Oil and Gas Goals and Policies (Sec. 22-5-100) and the Economic Development Goals and Policies (Sec. 22-6-20). The proposed Project would not compromise the goals of agricultural land use, residential land use in existing developments, or any other land use category. The current use in the vicinity of the Project area is dryland farming and oil and gas production for the portion of the proposed Project from the Kerr-McGee Gathering, LLC Lancaster Gathering Facility to about 0.5 mile north of Barley Avenue. The preferred pipeline route would be located outside residential properties from 0.5 mile north of Barley Avenue and would be located south of Barley Avenue from the residential area north of the roadway. Existing pipeline facilities including the meter station and the Kerr-McGee Gathering, LLC Lancaster Gathering Facility would be used for Project aboveground facilities. The use of these existing facilities would not interfere with existing land use or cause additional visual effects. The underground pipeline would allow continued agricultural uses. The alternative preferred route segments, located south of Barley Avenue, would avoid transportation and other effects in the vicinity of Barley Avenue and would be located along utility corridors. The proposed Project in this area is consistent with these land uses. The proposed Project would not impact effective and efficient delivery or place undue strain on adequate public facilities and services or other land use amenities because it would not disrupt utility service. The proposed Project would cross over 3 miles of agricultural land. However, impacts to agricultural areas and farmland would only be temporary during 17 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines construction. During operation of the Project, farmers would be allowed to continue to grow crops and farm within the easement. The only restrictions would be that the landowner could not locate buildings within the easement or otherwise obstruct pipeline access. Areas of sensitive natural environments, including riparian areas, waterbodies, and areas of potentially suitable habitat for threatened and endangered species are not prevalent within the Project area. Impacts to environmental resources such as air, water, waste, noise, and public health would be minimal. Mitigation practices would minimize impacts from dust generation and waste products (see discussion above regarding impacts from dust and waste). A SW MP would be developed and implemented to protect water quality during construction. Areas from which vegetation was removed during construction would be reclaimed as soon as possible following completion of construction. Wildlife may be temporarily displaced during construction, but would not be prohibited from returning to the site once the construction period has ceased. Noxious weeds would be managed in all surface disturbed areas. If herbicides are needed to control noxious weeds, they would be applied by a licensed contractor. A Weed Management and Revegetation Plan was developed for the proposed Project (Exhibit E). This plan describes the Weld County noxious weed list, weed control measures, and revegetation practices and provides a recommended weed management and revegetation implementation schedule. j. A decommissioning plan. All decommissioning activities would be performed in accordance with all federal and state regulations, using written procedures that meet or exceed safety requirements. There are no existing plans to decommission the Project. If temporary decommissioning of the pipeline is necessary for routine or emergency maintenance or repair, the pipeline would be depressurized using remote valve sets. Upon termination of operations of the Project, the natural gas pipeline would be abandoned in place and filled with inert gas that is used to clean out the pipeline and remove natural gas. The pipeline would be abandoned in place to avoid further surface disturbance or unnecessary construction. The proposed regulator station would be dismantled and removed and the site would be reclaimed. k. A description of any haul routes during construction, identifying the roads and bridges involved and the weight of the loads. The roads and highways within Weld County that would be utilized for delivery of construction materials, construction worker trips include U.S. Highway 85, CR 16 (Barley Avenue), CR 18, CR 20, CR 22, and CR 31. Access to the Project ROW would be on existing roads. Haul routes and worker commuting routes to the proposed Project during construction would primarily use CR 22 and Barley Avenue (CR 16). Currently, it is anticipated that the pipe would be shipped by truck from the coating facility in Sydney, Nebraska, directly to the Project. The pipeline materials and appurtenances would be delivered to the Project via U.S. Highway 85 and CR 16 or 22 and staged at the PSCo- 18 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines owned Fort Lupton Metering Station or the temporary staging area off CR 22 at the proposed regulator station site. Materials would then be moved to easement locations along the natural gas pipeline for assembly and installation via CR 31, CR 22, CR 20, and CR 18. As often as practicable, the pipe itself will be delivered, off-loaded, and strung out directly on the pipeline permanent/temporary easement to avoid double handling. Material deliveries and oversized vehicle traffic on public roadways would be limited to off-peak commuting times, as practicable, when background traffic tends to be lower (i.e., early morning and late afternoon) to minimize impacts to local commuters and for worker safety. Loads delivered by truck would vary in weight based on material being transported. Loads delivered by truck may reach 21 tons. All oversize/ overweight loads would comply with Colorado and Weld County regulations. I.

Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines Planning Questions 1. Explain, in detail, the proposed use of the property. Public Service Company of Colorado (PSCo) is proposing to construct and operate the Lancaster to Fort Lupton Natural Gas Pipeline Project (Project) in Weld County, Colorado. The proposed Project would reinforce the natural gas system infrastructure and provide improved and reliable service to existing and future customers in the region. The proposed Project is needed to meet the increased demand for natural gas services as a result of the recent population growth and urban development. The proposed Project would transport natural gas from the existing Kerr-McGee Gathering, LLC Lancaster Gathering Facility, located on the south side of County Road (CR) 22, between CRs 31 and 37 to the existing PSCo Fort Lupton Metering Station, located on the south side Barley Avenue, approximately 0.33 mile east of CR 31 (Exhibit A, Figure 1). The length of the new 16 -inch high-pressure lateral would be approximately 4.1 miles. The proposed Project would include construction of a proposed regulator station located within the Kerr-McGee Gathering, LLC Lancaster Gathering Facility property. The proposed regulator station would be located immediately south of the existing electrical substation owned by United Power Incorporated and west of the agricultural and oil and gas production parcel owned by Robert Warner. The regulator station would require the construction of four buildings, including one remote terminal unit/gas chromatograph (RTU/GC) building approximately 128 square feet in size, one metering building approximately 200 square feet in size, and two control valve buildings approximately 200 square feet in size. One temporary access road running south from CR 22 would be required for access to the proposed regulator station (Exhibit B). The access road would use an existing access off CR 22 that is currently used for the United Power Incorporated substation and run parallel to and east of the eastern property boundary of the Kerr-McGee Gathering, LLC Lancaster Gathering Facility. Up to three additional buildings would be built at a future date at the regulator station and are not part of the scope of this Project. They include one metering building 200 square feet in size and two control buildings, each approximately 200 square feet in size. The site plan for the proposed regulator station is included in Exhibit B. The proposed Project would tie into the Cherokee natural gas pipeline at the existing Fort Lupton Metering Station. Besides the interconnection of the proposed pipeline, up to two new buildings 100 square feet in size would be added to the existing metering station property as part of the proposed Project. The buildings would be used to protect pipeline equipment. Detailed drawings of the proposed Project are included in Exhibit B. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. For 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, see the Pipeline USR questions of the main document, subsection i. J-1 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines 3. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 23 (Zoning) and the zone district in which it is located. The proposed natural gas pipeline route is located in the A (Agricultural) Zone District in Weld County (Exhibit C). Per Section 23-3-40(D)(3) of the Weld County Code, Major Facilities of Public Utilities or Public Agencies, subject to the provisions of Section 23-4-420, are uses by special review and may be allowed in the A (Agricultural) Zone District upon approval of a permit. Per Section 23-3-20(L) of the Weld County Code, utility service facilities are a use by right in the A (Agricultural) Zone District. This Use by Special Review (USR) application requests approval of the proposed Project within the A (Agricultural) Zone District. 4. Describe what type of land uses surround the site. Explain how the proposed use is consistent and compatible with surrounding land uses. The proposed Project would be compatible with the surrounding land uses. Land surrounding the proposed Project is used for agricultural and oil and gas production from the Kerr-McGee Gathering, LLC Lancaster Gathering Station to about 0.5 mile north of Barley Avenue. In the area 0.5 mile north of Barley Avenue and along Barley Avenue, the proposed Project would be located outside the boundary of Aristocrat Ranchettes subdivision, near areas already used for industrial purposes by the city of Fort Lupton. The route surrounding the subdivision is currently occupied by linear corridors including roadways and utilities —primarily electric transmission lines. Both the Kerr-McGee Gathering, LLC Lancaster Gathering Station and the Fort Lupton Metering Station are existing facilities and their continued use for utility service is consistent with the proposed Project. The proposed Project would not interfere with any agricultural operations. Although most of the proposed Project would cross agricultural land, the natural gas pipeline easement would be able to be farmed following construction. PSCo has entered into agreements with landowners to avoid crop damages; however, if disturbance to crops occurs the landowner would be compensated at fair market value and would not impact subsequent growing seasons. The preferred route alternative segments are located in areas used for oil and gas facilities and along city of Fort Lupton property that includes a municipal water tank. The proposed Project is consistent with existing land use in this area. 5. What are the hours and days of operation? (e.g. Monday thru Friday 8:00 AM to 5:00 PM) Construction Construction work hours would be 7 AM to 7 PM Monday through Saturday unless otherwise specified by Weld County. Construction may occur on Sundays and other hours outside the 7 AM to 7 PM timeframe on an as -required basis. If unforeseen circumstances occur, or construction is delayed, PSCo may require construction outside the 7 AM to 7 PM timeframe to complete construction. Construction would occur in one shift. Construction of the proposed Project would be in conformance with all Weld County noise standards (Weld County Code 14-9-10 et seq.) as established in Section 25-12-101, CRS. Once operational, the natural gas pipeline would be in use at all times. J-2 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines Operation The natural gas pipeline would be buried underground. No noise would be generated by the natural gas pipeline. The proposed regulator station would be operated continuously (24 hour/day). There would be little to no noise (50-70 decibels) generated by the proposed regulator station. 6. List the number of full time and/or part time employees proposed to work at this site. Construction of the proposed Project would require from 20 to 100 workers on site for a period of approximately 4 months. Once construction has been completed and the Project is operating normally, a single person may be present on the Project site once a week for routine operation and maintenance. 7. If shift work is proposed include the number of employees per shift. Shift work is not proposed at the site. A single person may be present on the Project site once a week for routine operation and maintenance. 8. List the number of people who will use this site. Include contractors, truck drivers, customers, volunteers, etc. Construction of the proposed Project would require from 20 to 100 workers on site for a period of approximately 4 months. A single person may be present on the Project site once a week for routine operation and maintenance. 9. If this is a dairy, livestock confinement operation, kennel, etc., list the number and type of animals. This section is not applicable to the proposed Project, which would be a pipeline facility. 10. Describe the type of lot surface and the square footage of each type. (e.g., asphalt, gravel, landscaping, dirt, grass, buildings) The Project right-of-way (ROW) would be restored to preconstruction conditions with the exception of the proposed regulator station site and associated access road and the proposed buildings at the Fort Lupton Metering Station. The four proposed buildings at the proposed regulator station include an RTU/GC building approximately 128 square feet in size, one metering building 200 square feet in size, and two control valve buildings approximately 200 square feet in size. Up to three additional buildings would be built at a future date and are not part of the scope of this Project. They include one metering building approximately 200 square feet in size and two control buildings, each approximately 200 square feet in size. Up to two new buildings, each approximately 100 square feet in size would be added to the existing metering station property as part of the proposed Project. The buildings would be used to protect pipeline equipment. The site plan for the proposed regulator station and Fort Lupton Metering Station is included in Exhibit B. J-3 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines The pipeline would be approximately 4.1 miles long, and would have a permanent 50 -foot - wide easement and an additional 50 -foot -wide construction easement. Additional information regarding restoration of the Project ROW is provided in Exhibit E. 11. How many parking spaces are proposed? How many handicapped (ADA) parking spaces are proposed? No parking spaces are planned for the proposed Project. Construction workers would use the existing PSCo property (existing Fort Lupton Metering Station and the proposed regulator station site), and the Project ROW to park during construction hours. 12. Explain the existing and proposed landscaping for the site. The Project ROW would be restored to preconstruction conditions with the exception of the proposed regulator station site and metering station site. The four proposed buildings at the proposed regulator station include an RTU/GC building approximately 128 square feet in size, one metering building approximately 200 square feet in size, and two control valve buildings approximately 200 square feet in size. Up to three additional buildings would be built at a future date and are not part of the scope of this Project. They include one metering building approximately 200 square feet in size and two control buildings, each approximately 200 square feet in size. Up to two new buildings approximately 100 square feet in size would be added to the existing Fort Lupton metering station property as part of the proposed Project. Additional information regarding restoration of the Project ROW is provided in Exhibit E: 13. Describe the type of fence proposed for the site (e.g., 6 foot chain link with earth tone slats) The proposed regulator station would be completely surrounded by 7 -foot security fence topped with a three -strand barbed wire outrigger. The fence would be shared with the existing Kerr-McGee Gathering LLC fence on the west site of the proposed site. Additional temporary chain link fencing or orange exclusion fencing may be used surrounding the staging areas or other construction areas during construction. 14. Describe the proposed screening for all parking and outdoor storage areas. If the site is located in a floodplain, outdoor storage is restricted. The proposed regulator station would be completely surrounded by 7 -foot security fence topped with a three -strand barbed wire outrigger. Additional temporary chain link fencing or orange exclusion fencing may be used surrounding the staging areas or other construction areas. No other screening is proposed. 15. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. Upon completion of construction, the Project ROW would be returned to preconstruction conditions with the exception of the footprint of the RTU building and the two metering buildings at the proposed regulator station site, which would remain in place for the life of the J-4 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines Project. Revegetation methods are described in Exhibit E. There are no current plans to decommission the proposed Project. However, if the Project is decommissioned and terminated in the future, the regulator station and Fort Lupton Metering Station would be removed and the area would be reclaimed. The natural gas pipeline would be abandoned in place and filled with inert gas that is used to clean out the pipeline and remove natural gas. 16. Who will provide fire protection to the site? The Fort Lupton Fire Protection district would provide fire protection to the site in the construction and operations phases of the proposed Project. 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. An approximate construction sequencing schedule for the Proposed Project is as follows: • Boring and trenching of the pipeline beginning August 2017; expected completion: December 2017 • Construction of the proposed regulator station, including four buildings, gravel surface, 7 -foot security fence topped with a three -strand barbed wire outrigger, and construction of the access road all beginning September 2017; expected completion: December 2017 • Construction of the Fort Lupton Metering Station including up to two buildings beginning September 2017; expected completion: December 2017 • Hydrostatic testing: December 2017 • Commissioned and in-service: December 2017; possibly into first quarter 2018 • Reclamation activities including revegetation and grading ongoing throughout construction and completed September 2018 Reclamation activities including revegetation and grading ongoing throughout construction and completed September 2018 Engineering Questions 1. Describe how many roundtrips/day 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) Please see Exhibit L for a more detailed traffic narrative. A summary is provided here. The total number and type of construction vehicles that would access the site each day include: • Pickup trucks: 7 trips per day • Welding trucks: 10 trips per day • Non-destructive examination "x-ray" trucks: 6 trips per day • Semi -truck pipe delivery: 4-5 trips per week • "Low boy" equipment transport trucks: 5 per week • Bus/van: 6 trips per day J-5 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines It is estimated that approximately 68 semi -truck pipe deliveries would be required for the proposed Project. These deliveries would take place over about 4 months as necessary for construction of the pipeline, or an average of 17 deliveries per month or an average of 4-5 deliveries a week. A single person in a pickup truck may be present on the Project site once a week for routine operation and maintenance. Trip generation for the construction phase of the proposed Project within unincorporated Weld County would be related to the delivery of materials and equipment to the staging areas, construction activities related to installation of the natural gas pipeline (workers, trucks, and equipment traffic), dust suppression, and hydrostatic testing. It should be noted that the hydrostatic testing of the entire length of the installed natural gas pipeline would be performed at the completion of construction. Construction work hours would be 7 AM to 7 PM Monday through Saturday unless otherwise specified by Weld County. Construction may occur on Sundays and other hours outside the 7 AM to 7 PM timeframe on an as -required basis. Substantial construction of the proposed Project is expected to begin by the end of the summer 2017, with commissioning and testing of the entire natural gas pipeline/facilities expected to be completed by the end of December 2017. The in-service start date of the natural gas pipeline is expected in December 2017, possibly into the first quarter of 2018. The pipeline would be bored under all county road crossings. A Traffic Control Plan would be submitted to the County as required with the County access permit application. The Plan would provide measures for traffic control during Project construction. Road closures are not expected during construction of the proposed Project. 2. Describe the expected travel routes for site traffic. Access to the easement would be on existing roads with the exception of one additional permanent access road required for access off CR 22 to the proposed regulator station. Haul routes and worker traffic to the proposed Project during construction would primarily use CR 22 and Barley Avenue (CR 16). Currently, it is anticipated that the pipe would be shipped by truck from the coating facility in Sydney, Nebraska, directly to the Project. The pipeline materials and appurtenances would be delivered to the Project via U.S. Highway 85 and CR 16 or 22 and staged at the PSCo- owned Fort Lupton metering station or the temporary staging area off CR 22 at the proposed regulator station site. Materials would then be moved to the Project ROW for assembly and installation via CR 31, CR 22, CR 20, and CR 18. As often as practicable, the pipe itself will be delivered, off-loaded, and strung out directly on the pipeline permanent/temporary easement to avoid double handling. Material deliveries and oversized vehicle traffic on public roadways would be limited to off-peak commuting times, as practicable, and staged at the PSCo-owned Fort Lupton metering station or the temporary staging area off CR 22 at the proposed regulator station site. Materials would then be moved to designated locations along the natural gas pipeline for assembly and installation. J-6 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines 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.) It is anticipated that approximately 60 percent of construction traffic would originate from the west (primarily via CR 22 and Barley Avenue). Approximately 20 percent of the construction traffic would originate from the south (primarily via U.S. Highway 85), and approximately 20 percent of the construction traffic would originate from the north (primarily via U.S. Highway 85). 4. Describe the time of day that you expect the highest traffic volumes from above. Peak travel times during construction of the proposed Project are expected from 6 AM to 7 AM and from 5 PM to 6 PM. Materials hauling would take place during various times of the day. 5. Describe where the access to the site is planned. Access to the proposed Project would be from private PSCo-owned easements and fee - owned land, private land, and county thoroughfares along the length of the natural gas pipeline. Existing PSCo facilities and temporary construction easement would be used as staging areas for temporary storage of construction materials and construction vehicle parking. Access to the construction areas and for operation of the proposed Project would be from existing county roads and via the pipeline easement across private property. One access road is proposed from CR 22 to the proposed regulator station using an existing access off CR 22. An access permit application is included as Exhibit D. 6. Drainage Design: Detention pond summarized in a drainage report is required unless the project falls under an exception to stormwater detention requirements per code section 23-12-30 F.1. Does your site qualify for an exception to stormwater detention? If so, describe in a drainage narrative the following: 1. Which exception is being applied for and include supporting documentation. As discussed in the pre -application meeting with Weld County on November 18, 2017, and documented in Exhibit I, pre -application case file, the proposed pipeline would be excluded from the stormwater detention requirements per code section 23-12-30 (F.1) under exception 5: Pipelines or transmission lines. The proposed regulator station would be excluded from the stormwater detention requirements per code section 23-12-30 (F.1) under item 13: A parcel greater than 1 gross acre and less than or equal to 5 gross acres in size is allowed a onetime exception. Drawings of the Project components showing size and location of these proposed components are included in Exhibit B, detailed engineered drawings. 2. Where the water originates if it flows onto the property from an offsite source There are no water conveyances including channels or streams that flow onto the Project ROW from an off -site source. J-7 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines A wetland and other waters of the United States (WoUS) delineation, including a desktop analysis and field survey, was completed as part of the biological resources assessment. The delineation revealed one wetland in the Project ROW. The wetland appeared to be isolated and there were no streams or other surface water features observed in the Project ROW. The proposed Project would avoid all impacts to potential WoUS if practicable. If impacts to wetlands cannot be avoided, PSCo would comply with all federal and state regulations for impacts to potential WoUS. 3. Where it flows to as it leaves the property The proposed Project would cross Riley Mound, a topographic high point. Water flows off Riley Mound in all directions and eventually flows toward Fulton Ditch and Speer Canal, both of which flow to the north. 4. The direction of flow across the property No water conveyances, including channels or streams, are present in the Project ROW. Elevation contours are included on Figure X. After construction, the Project ROW would be returned to preconstruction conditions and contours. Therefore, water flow across the property would not be altered by the Project. 5. If there have been previous drainage problems with the property There are no known drainage problems in the Project ROW. B. Does your site require a stormwater detention pond? The site does not require a stormwater detention pond. Environmental Health Questions What is the drinking water source on the property? If utilizing a drinking water well include either the well permit or well permit application that was submitted to the State -Division of Water Resources. If utilizing a public water tap include a letter from the Water District, a tap or meter number, or a copy of the water bill. This is an unmanned facility and drinking water would not be required during operation. Individual bottled water or water cooler service would be provided to construction workers. The proposed Project would require hydrostatic test water during the final phases of construction. The natural gas pipeline would be pressure tested once backfilling has been completed to ensure that the system is capable of withstanding the designed maximum allowable operating pressure (MAOP). The quantity of water required for hydrostatic testing is approximately 487,000 gallons. Water for the testing would be supplied from an approved municipal water source in the vicinity of the proposed Project and would either be obtained from a hydrant or delivered to the Project site via a water haul truck. J-8 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines Water for dust suppression would be obtained from municipal sources approved by jurisdictions in the Project area prior to construction and would be delivered via a water haul truck. Water requirements for dust suppression would be approximately 500,000 gallons. What type of sewage disposal system is on the property? If utilizing an existing septic system, provide the septic permit number. If there is no septic permit due to the age of the existing septic system, apply for a septic permit through the Colorado Department of Public Health and Environment (CDPHE) prior to submitting this application. If a new septic system will be installed please state "a new septic system is proposed". Only propose portable toilets if the use is consistent with the CDPHE's portable toilet policy. The proposed Project is an unmanned facility and a sewage disposal system would not be required during operation. During construction of the proposed Project port -a -lets would be used. 3. If storage or warehousing is proposed, what type of items will be stored? Two material staging and laydown areas would be established, one on the existing Fort Lupton Metering Station parcel and one at the proposed regulator station. Additional staging of materials would occur within the temporary construction easement and temporary usage areas for the pipeline. No other laydown or staging areas would be required. No permanent storage would be associated with the proposed Project. The Project ROW would also be used as necessary to store pipe prior to installation; and to store necessary construction equipment. The staging areas would be utilized for the following temporary uses: • Pipe and pipe materials including valves, fittings, and other miscellaneous materials • Limited parking for employees • Portable toilet • Construction equipment PSCo would provide Weld County documentation from each property owner that states that the property owner has entered into an agreement with PSCo for temporary use of the land, for construction easement, prior to construction. No additional odorant storage would occur during operation of the proposed Project. The mercaptan odorant storage is already on site at the existing Fort Lupton Metering Station in the permanent holding tanks. No storage of materials along the natural gas pipeline easements would occur following completion of construction. J-9 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines 4. Describe where and how storage and/or stockpile of wastes, chemicals, and/or petroleum will occur on this site. Hazardous materials would not be stored in the Project area and no hazardous materials would be generated during construction of the proposed Project. A fueling vehicle or fueling tank would service vehicles within the Project ROW as necessary. No additional odorant storage would occur during operation of the proposed Project. The mercaptan odorant (a sulfur -containing organic chemical substance, sold as Scentinel® E) storage is already on site at the existing Fort Lupton Metering Station in the permanent holding tanks. No storage of materials would occur in the Project ROW following completion of construction. Construction waste would be stored at the staging areas in commercial dumpsters that would be regularly serviced. All construction waste, including trash and litter, garbage, and other solid waste would be removed to a disposal facility authorized to accept such materials. Material disposal (i.e., clean fill) would be taken to approved disposal locations, including but not limited to: • Erie Front Range Landfill, 1830 CR-5, Erie, CO 80516 • Tower Landfill, 8480 Tower Road, Commerce City, CO 80022 • D&R Transfer Station, 6091 Brighton Boulevard, Commerce City, CO 80022 Waste management best management practices (BMPs) for protection of water resources are included in Table 1 of the Application. 5. If there will be fuel storage on site indicate the gallons and the secondary containment. State the number of tanks and gallons per tank. In some instances, the contractor may require a fueling tank. The tank would typically hold approximately 500 gallons. The tank would meet Occupational Safety and Health Administration requirements for secondary containment. Fueling vehicles and tanks would fuel construction vehicles within the Project ROW and at the staging areas as required. Fueling vehicles would be equipped with spill kits and fire extinguishers and personnel would be properly trained in spill prevention, control, and countermeasures. No vehicle maintenance would occur on site, and appropriate BMPs would be utilized and documented if on -site maintenance became necessary. 6. If there will be washing of vehicles or equipment on site indicate how the wash water will be contained. No vehicle or equipment washing would be performed on site during construction or operation of the proposed Project. J-10 Lancaster to Fort Lupton Natural Gas Pipeline Project Site -Specific Development Plan and Use by Special Review Permit Application for Pipelines 7. If there will be floor drains indicate how the fluids will be contained. No liquids would be stored inside any of the proposed buildings. The buildings would have a concrete slab foundation and would be a prefabricated drop over style metal building. 8. Indicate if there will be any air emissions. (e.g., painting, oil storage, etc.) Impacts to air quality in the Project area would be short term, transient, and limited to the construction period. Construction activities would be sequenced and no more than 2,500 feet of the trench would be open at one time. Vegetation clearing, trenching, boring, re -grading, and construction vehicles and equipment may produce fugitive dust or exhaust emissions during the construction phase of the proposed Project. Dust suppression would be conducted during construction. Water for dust suppression would be obtained from municipal sources. No air quality modeling has been completed for the proposed Project. Based on the amount of the temporary disturbance area, PSCo is obtaining a General Construction Permit from the Colorado Department of Public Health and Environment, and preparing a Fugitive Dust Plan and Air Pollutant Emission Notice (APEN). The Fugitive Dust Plan would be completed and the APEN would be obtained prior to construction. Construction vehicles and equipment would be shut off when not in use to limit the amount of exhaust emissions. Wind patterns common to the area would act as a dispersion mechanism for air pollutants. The Project area is in attainment of all National Ambient Air Quality Standards, with the exception of the Front Range ozone control area, which is nonattainment for the 8 -hour ozone standard. No air emissions would result from operation of the natural gas pipeline or Fort Lupton Metering Station. The operation of the proposed Project would comply with the air quality regulations promulgated by the Colorado Air Quality Control Commission. 9. Provide a design and operations plan if applicable. (e.g., composting, landfills, etc.) According to correspondence between Kim Ogle, Weld County Planner, and John Heule, Tetra Tech, on Wednesday January 4, 2017, a design and operations plan will not be required for the proposed Project. 10. Provide a nuisance management plan if applicable. (e.g., dairies, feedlots, etc.) Not applicable. 11. Additional information may be requested depending on type of land use requested. PSCo will gladly provide additional information upon request to the applicant listed in Sec. 23- 2 -510. —Application requirements of this application package.

List the type, size (square footage), and number of existing and proposed structures. Show and label all existing and proposed structures on the USR drawing. Label the use of the building and the square footage. Building permits would be obtained for all structures as necessary and would have state - issued insignia. One proposed regulator station and one existing metering station would be required for the proposed Project. The proposed regulator station site would be approximately 100 by 250 feet (25,000 square feet) and include four buildings. The buildings at the proposed regulator station include an RTU/GC building approximately 128 square feet in size, one metering building approximately 200 square feet in size, and two control valve buildings approximately 200 square feet in size. Up to three additional buildings would be built at a future date and are not part of the scope of this Project. They include one metering building approximately 200 square feet in size and two control buildings, each approximately 200 square feet in size. Up to two new buildings approximately 100 square feet in size would be added to the existing Fort Lupton metering station property as part of the proposed Project. The buildings would be used to protect pipeline equipment. The location of these buildings are shown in Exhibit B. 2. Explain how the existing structures will be used for this USR? The proposed regulator station, located at the north end of the proposed pipeline, would be used to control and adjust the pressure of the natural gas in the pipeline before transportation of the natural gas. The existing metering station would be used to document and report the pressure and is the interconnection point for gas delivery into the existing Cherokee natural gas pipeline. 3 List the proposed use(s) of each structure.
