DESCRIPTION OF PROPOSED USE: This USR application is referred to as the Johnstown Compressor Station application and is submitted by Kerr McGee Gathering, LLC (KMG), an Anadarko Petroleum Corporation (APC) Company. APC and KMG operate nearly 5,000 oil and gas wells in the Denver-Julesburg (DJ) Basin with the vast majority being located in Weld County, Colorado. All of these wells produce varying amounts of natural gas that need to be routed via a system of underground pipelines through a number of compressor stations in Weld County. This proposed site is located on parcel #105918000015 and is owned KMG. It is currently zoned Agricultural and surrounded by parcels that are also zoned Agricultural. The parcel is also bordered by the municipal boundary for the City of Johnstown. There is currently farmland with extensive oil and gas operations already in place. A compressor station helps the transportation process of natural gas from one location to another. Natural gas, while being transported through a pipeline, needs to be constantly pressurized in certain distance intervals (from 4 up to 100 miles). The gas in the compressor station is pressurized by special turbines, compressors, and engines. The proposed compressor station will be owned and operated by KMG. Proposed Johnstown Compressor Station Exhibit A — Vicinity Map Proposed Johnstown Compressor Station T4N-R67W Sec 18: Part of the SE4 Weld County, Colorado 2 Compressor Station: The proposed operation outlined in this application, includes various compression equipment that will be used to compress and transport natural gas. The equipment being proposed will include compressors, vapor recovery units, separators, dehydrators, launchers, coalescers, storage tanks, lightning protection, a communication tower, and additional supporting compression equipment. There will also be an electric switch yard consisting of a transformer to step down the incoming distribution voltage from 69 kV to 12.7 kV. The switch yard is included within the compressor station's fence area for safety and to reduce the total footprint. This allows the burial of the low voltage lines into the station instead running the larger power lines overhead across the parcel into the station. A communications tower is also proposed, to allow the site to be operated remotely. The communications tower will be a 70 foot tall tower and powered from the Compressor Station UPS. There will be 1-2 dishes on the tower and it will handle all communications on site, and co -location will be possible. Please see the Site Plan in the Appendix for a more detailed layout and description of the proposed equipment and a reasonable facsimile of the communications tower. The compressors on site operate 24 hours a day, 7 days a week, 365 days a year. However, the station will automatically adjust to run only those engine -compressors needed to adequately handle the volume of gas flowing through the pipeline. Facility Ownership: Johnstown Compressor Station Kerr-McGee Gathering, LLC 1099 18th St., Suite 1800 Denver, CO 80202 CONSISTENCY WITH THE INTENT OF THE WELD COUNTY CODE, CHAPTER 22 OF THE COMPREHENSIVE PLAN The proposed use is consistent with Chapter 22 and any other applicable code provisions or ordinance in effect. Section 22-2-10(D) emphasizes the "Extraction of natural resources as an important part of the economy of Weld County. Such extraction operations should minimize the impacts on agricultural lands and agricultural operations." This compressor station and laydown yard will contribute to the expansion of the County's economic base by providing increased capacity for future oil and natural gas production. The proposed addition of a compressor station and laydown yard in this location conserves land by eliminating the need for these facilities elsewhere in Weld County. In addition, KMG is owner of the property and is choosing to allow agricultural operations to remain in place. This is a testament to the minimal impacts of the proposed compressor station on the existing agricultural operations and to the applicability of the land use in this case with Section 22-2-10 "A. Goal 2. Continue the commitment to viable agriculture in Weld County through mitigated protection of established (and potentially expanding) agricultural uses from other proposed new uses that would hinder the operations of the agricultural enterprises ". Furthermore, after the addition of this compressor station, the agricultural use of this land and surrounding land will remain unchanged, which is in agreement with Section 22-5-100.B (OG. Goal 2) strive to, "Ensure that the extraction of oil and gas resources conserves the land and minimizes the impact on surrounding land and the existing surrounding land uses." Proposed Johnstown Compressor Station T4N-R67W Sec 18: Part of the SE4 Weld County, Colorado 3 Additionally, Section 22-5-100.A (OG. Goal I) states: "Promote the reasonable and orderly exploration and development of oil and gas mineral resources, " A compressor station supporting a network of pipelines is the most orderly manner of transferring the developed gas resource within the county. The Use by Special Review application for this Facility is part of a comprehensive gas processing network and is necessary to move larger volumes of gas. These larger volumes are due to increases in drilling activity and projected additional production increases anticipated by producers in the Weld County area. Moreover, Section 22-5-100.B, (OG. Policy 2.9) outlines the objective to, "Impose protective measures through available state, County and federal regulations to ensure that the mineral operator conducts operations in a manner that will minimize current and future environmental impacts." The Spill Prevention and Countermeasure Plans for the proposed Johnstown Compressor Station are developed in accordance with federal Environmental Protection Agency (EPA) standards, and all activities will be in compliance with the permit and control provisions of the state regulations (Colorado Air Quality Control Program, Title 25, Article 7, C.R.S. as applicable). CONSISTENCY WITH THE INTENT OF THE WELD COUNTY CODE, CHAPTER 23 (ZONING) AND THE ZONE DISTRICT IN WHICH IT IS LOCATED. Oil and gas facilities are allowed as a use by right in the A (Agricultural) Zone District. However, oil and gas support and service operations such as a Compressor Facility require the approval of a Use by Special Review Permit. The proposed use is consistent with the intent of the A (Agricultural) Zone District. Section 23-3-40.A.2 of the Weld County Code provides for Oil and Gas Support and Service, and Section 23-3-40.L of the Weld County Code provides for a communications tower greater than 70 feet in height as a Use by Special Review in the A (Agricultural) Zone District. 2. SURROUNDING USES AND COMPATIBILITY WITH SURROUNDING USES. There are currently no USR permits on the proposed site. The proposed facility does not interfere with the existing use of the area, and remains compatible with the current zoning. Furthermore, the parcel acreage also encompasses extensive multi -well oil and gas operations and pipeline easements. The facility location being proposed will abut many of the existing operations and allow for continued agricultural uses. This is consistent with Sec. 23-2-240. All. States that "Uses by Special Review in the A (Agricultural) Zone District shall be located on the least prime soils on the property in question unless the applicant can demonstrate why such a location would be impractical or infeasible." 3. DETAILS OF THE SITE a. Number of people who will use this site There are no permanent employees on this site. The site is visited by a KMG/APC employee on a daily basis. The employee is typically not on site for longer than one to two hours at a time. Given the short amount of time an employee is on site, permanent water and sewer service is not necessary. The site is monitored 24 hours a day 7 days a week by the computers at the company's gas control centers in Platteville. Bottled water and a port -a -let will be utilized by personnel visiting the facility and the laydown yard. b. Number of employees proposed to be employed at this site There will be no full time employees at the Johnstown Compressor Station. One employee may visit the site on a daily basis. Proposed Johnstown Compressor Station T4N-R67W Sec 18: Part of the SE4 Weld County, Colorado 4 c. Hours of operation The compressors on site run 24 hours a day 7 days a week based on demand. On average one employee will visit the site once each day in a pick-up truck. Trucks will generally only come to the site during the hours of 8 am to 5 pm unless there is an emergency. rL Type and number of structures to be built on this site Please see the Site Plan in the Appendix for a more detailed layout of all proposed buildings and communication tower. e. Type and number of animals There are no animals on site. f. Kind of vehicles that will access this site and how often A KMG/APC employee will visit the site once each day in a pick-up truck. Larger vehicles with trailers may come to the site for delivery, repair, and maintenance purposes only, on a periodic basis. g. Fire Protection Front Range Fire Rescue provides fire protection to this area. A referral packet will be sent to the District by the County. h. Water source on the property There are no full time employees on site. A KMG/APC employee will visit the site on a daily basis. Due to the lack of employees permanently on site, a water connection is not necessary. Should the status of employees on site change, water would be requested from Northern Colorado Water District or obtained from a new well on site as appropriate. Bottled water will be available during construction and during operation. L Sewage disposal system There is no need for a sewer disposal system. Employees will have access to use a port -o -let. This facility will be serviced by Waste Management for waste removal. A small dumpster will also be on site for the disposal of household waste. Should a water source later be required, there appears to be ample space on the lot to provide for an ISDS for sewage disposal. j. Storage or warehousing No storage or warehousing is being proposed as part of this application. 4. PROPOSED LANDSCAPING It is anticipated that the compressor facility and laydown area will be enclosed with a chain -link fence approximately 6 to 7 feet high with a potential 3 foot outrigger and barbed wire to prohibit vandalism and theft not only during the construction phase but also as a security device for the life of the facility. A precast concrete wall is also being proposed for screening specific areas of the facility. Please see USR drawings for Visual Mitigation Plan. Reclamation Procedures Upon termination of the proposed project, all equipment would be removed. The ground would be re- graded to accommodate agricultural uses or be re -vegetated to 80% of pre -disturbance vegetative cover in accordance with the COGCC 1000 Series Rules. The pre -disturbance vegetation cover shall be determined by the undisturbed surrounding area. KMG would also be willing to evaluate coordinating reclamation efforts with Weld County Extension, Public Works, and the Soil Conservation District. Proposed Johnstown Compressor Station T4N-R67W Sec 18: Part of the SE4 Weld County, Colorado 5 5. STORM WATER DRAINAGE A detention pond has been added to address site drainage. A drainage narrative will also be submitted and will provide additional details. 6. CONSTRUCTION PERIOD Construction of the proposed facility is expected to commence shortly after the site plan and Use by Special Review application are approved. We expect construction to be complete by the end of 2019. 7. STORAGE & STOCKPILING OF WASTES / WASTE HANDLING PLAN The following wastes are expected to be generated on site from the operations and maintenance of compressor station related equipment. Typically these are used as coolants and lubricants and need to be changed on a regular basis. Product Name Used Triethylene Glycol (TEG) Used Cat NGEC Premix 50/50 Used Mobil Pegasus 805/Oily Water Quantity 25 gal 25 gal 100 gal The wastes listed above are generated on a monthly basis and either recycled or disposed of by Mesa Oil. The replacement products needed as part of this equipment maintenance will be stored in steel tanks mounted on steel skid mounted containment units. The seams will be sealed. Each unit will be sufficient to contain 1.5 times the tank capacity. Additionally, oil and coolant are also stored within the compressor units themselves and spills are contained by the structural steel skid of the actual compressor. A list of associated SDS sheets are attached in the appendix of this application. No Chemicals will be stored facility, nor will any vehicles be washed. The waste generated at the compressor station and the laydown yard from the portable toilets are emptied weekly, and the dumpsters either weekly or biweekly. The roll -off is emptied on a call -out basis.

If a spill/release meets or exceeds any regulatory reporting criteria, KMG will report the spill to the appropriate regulatory agency(s). KMG's standard operating procedures are to excavate the impacted soils and transport them to a licensed disposal facility. As appropriate, confirmation soil samples will be collected from the excavation for laboratory analysis. Laboratory analytical results will be utilized to demonstrate effective remediation to below the appropriate regulatory standards. The laboratory reports will be included in any written report to a Proposed Johnstown Compressor Station T4N-R67W Sec 18: Part of the SE4 Weld County, Colorado 6 regulatory agency. Following completion of the excavating activities, the area will be backfilled and returned to its pre-release grade. Please see Appendix for all Safety Data Sheets (SDS) of wastes generated. No vehicles be washed on site. Additionally, All KMG/APC and contractor activities will be operated in a manner that prevents spills and releases of crude oil, natural gas, produced water and other wastes to the environment. Non -routine waste (e.g. spills or releases) will be managed in accordance with KMG/APC's Emergency Response and Oil Spill Contingency Plan. Spills, as appropriate, will be reported to the proper regulatory agency(s). Additionally, a site -specific Spill Prevention Control and Countermeasure (SPCC) Plan will be developed to outline appropriate actions to be taken in the event of a spill or release. The SPCC Plan, in conjunction with the Emergency Response and Oil Spill Contingency Plan, will ensure that all appropriate response actions are taken and that all waste will be handled in accordance with applicable rules and regulations. Both documents are written in accordance with requirements set forth by the Environmental Protection Agency. A copy of this plan will be submitted to Weld County within six months after start of operations. 8.

KMG has area wide permit coverage under the State Colorado Department of Public Health and Environment, Water Quality Control Division, Permit Number COR-039803. h. Road Maintenance Agreement KMG will obtain an Improvements and Road Maintenance Agreement for WCR 44. 4. TRAFFIC Compressor Station: The construction process for the compressor station will involve site grading with equipment, including but not limited to, motor graders, front end loaders, excavation equipment, and possibly scrapers. Heavy hauls involving the compressor units and some of the larger process equipment will be necessary, as will the use of large truck mounted cranes to unload and set this equipment. The length of the heavy haul trailers will determine the required access to the site off the county roads, although typically this has been an apron off the county road of about 75 to 100 feet necking down to a fenced and or gated opening of around 40 feet. This would depend on the available turning radius off the county road. There will also be concrete trucks and pumpers on a regular basis during construction. Anticipated staffing during the construction of the facility is estimated at 30 to 40 personnel during peak construction, 3 to 4 office trailers and 5 to 8 tool and parts vans/conex buildings. Please see Use by Special Review Questionnaire for traffic detail post construction. Laydown Yard: KMG will level then grade the laydown yard. During the construction phase of the project, APC/KMG, will use or contract to have water trucks utilized to maintain dust suppression and fugitive particulate emissions. Also, the Stormwater Management Plan will be followed to mitigate soil erosion during construction. After completion of construction, the perimeter of the property will be stabilized using appropriate native vegetation, usually a combination of dry land /grass mixture or crop. Additionally KMG will gravel all access and driving surfaces affected. Areas inside the fence line will be compacted and stabilized. If necessary, KMG will also use or contract to control dust after construction. 6. FIRE AND EMERGENCY RESPONSE There is adequate provision for the protection of the health, safety, and welfare of the inhabitants of the neighborhood and county. All roads leading to the site and within the site will be designated and maintained to support fire apparatus. A turnaround may be constructed as necessary to accommodate fire apparatus. In addition to above -referenced rules and regulations, APC/KMG is also subject to COGCC Rule 6064 pertaining to fire prevention and protection. APC/KMG has support personnel in the field or on call at all times to provide technical assistance in fire prevention and elimination. Proposed Johnstown Compressor Station T4N-R67W Sec 18: Part of the SE4 Weld County, Colorado 10 III. NOISE ABATEMENT PLAN Introduction The Johnstown Compressor Station is a proposed Kerr McGee Gathering, LLC (KMG) facility located in Weld County. This facility is needed to help transport the increasing amounts of natural gas to processing facilities where it is then prepared for sale to market. KMG has taken steps to attenuate noise originating from this site and will continue to take the necessary actions to comply with Weld County noise regulation. The following plan outlines how noise is mitigated at the Johnstown Compressor Station site. Location and Surrounding Land Use The proposed Johnstown Compressor Station access road is located at the intersection of WCR 44 and WCR 15 in an area zoned for agriculture. Proposed Improvements KMG is proposing the installation of eight (8) compressors. There will be eight (8) CAT3608/Ariel JGC- 3, or similar units. There will also be one 60,000 gallon slug catcher, four (4) 35 MMscfd coalescing filter separators, four (4) 35 MMscfd TEG dehydrator-condenser-VRU's, one condensate pump and LACT skid, one (1) communication tower, two (2) lightning protection masts, and associated piping and electrical infrastructure. Noise Regulation and Goal There is no equipment presently at the proposed site. Under the current regulations, permissible noise levels will not exceed 55 dBA during the day or 50 dBA at night. KMG will ensure the installed equipment complies with these regulations. KMG also has the ultimate goal of not exceeding 50 dBA at all times and will be measured at the property boundary on a regular basis. Efforts to Date KMG has already begun efforts to reduce noise on -site by installing with each compressor, a combustion air intake silencer, a hospital grade muffler on the engine exhaust, and electric driven compressor coolers. Assessment and Attenuation Upon operation KMG will conduct a noise survey to determine if noise levels meet local noise requirements. If noise exceeds levels then sound walls or insulation will be built around the identified problem equipment. Ventilation packages may also need to be installed to ensure that the equipment is able to operate while being completely enclosed.

The compressor station has S Gas compressor (reciprocating) and 2 electric motor driven reciprocating compressor. The purpose of the noise study is to predict the noise level for the Johnstown compressor station at the property line and fence line boundary of the site and ensure the noise levels meet the Weld County noise ordinance limit. A previous noise study report (Rev A) was issued showing the predicted noise levels for Johnstown compressor station. The situation that has been considered in the previous report are as follows: Situation 1: Equipment are modelled with ground elevation of 4810' and chain link fence around the fence line Situation 2: Equipment are modelled with ground elevation of 4810' and a noise protection brick wall was modelled at the south side of the fence line. The rest 3 sides are modelled with chain link fence. In this report two other options for noise control has been considered as described below: Situation 3: Equipment are modelled at the elevation of 4810 feet. 8 feet brick wall was modelled at the North and South side of the plant. West and East side has chain link fence. Situation 4: Equipment are modelled at the elevation of 4810 feet. 8 feet brick wall was modelled at all four side of the fence line. 1.2 Definitions Parameters Definition 1/1 Octave bands A 'constant percentage bandwidth' where each of the octave bands is a frequency band for which the highest frequency is twice the lowest frequency. 1/3 Octave bands A 'constant percentage bandwidth' where each of the octave bands defined above is divided into 3 bands (i.e. each band is approximately 1/3 the 'width' of the octave bands), providing a more discreet analysis of the frequency content of a sound field. Decibels A relative unit of measurement widely used in acoustics, electronics and communications. Ten times the logarithm of the ratio of a measured quantity to a reference value. The ratio may be sound power, sound pressure, voltage, sound intensity, etc. dB(A) The linear dB scale is usually modified by the A -weighting 'filter' to simulate the non-linear response of human hearing, The application of this filter is denoted by appending an 'A'; to the dB units. The unit may be presented as dBA or dB(A). US01070_Noise Study I May 2019 Page 6 of 15 4 • • wood Anadarko Johnstown Compressor Station Noise Assessment Report Report Parameters Definition RMS The mathematical means by which a signal that is regularly oscillating around a mean of zero, is 'averaged' such that the result is not zero. This involves squaring, averaging and then taking the square root of the signal. Rw The Weighted Sound Reduction Index is a single number index used to characterise the level of sound insulation provided by a structure such as a wall, window, door, or ventilator as measured in a lab. It is defined in the series of international standards ISO 140 (parts 1-14). R'w The Apparent Weighted Sound Reduction Index is a single number index used to characterise the level of sound insulation provided by a structure such as a wall, window, door, or ventilator as measured in -situ. It is defined in the series of international standards ISO 140 (parts 1-14). Sound Power The total sound energy radiated by a source in all directions, measured in watts. Under fixed operating conditions the sound power of a source is constant and independent of the environment in which it is operating. Sound power is often used to describe the noise emission of a machine and allows comparison of the 'source strength' of machines. Sound Power Level (SWL) , Ten times the logarithm of the ratio of the sound power to the sound power reference level. Sound power levels can only be calculated from measured sound pressure or sound intensity levels. Sound power levels are usually denoted by Lw and the reference sound power is 10 pW. Sound Pressure The difference between the pressure caused by a sound wave and the ambient pressure of the medium it is passing through, measured in Pascals, Pa. Sound Pressure Level (SPL) Twenty times the logarithm of the measured RMS sound pressure divided by the reference sound pressure. Sound pressure levels are usually denoted by Lp and the reference sound pressure is 20 pPa. Sound Transmission Class An integer rating scheme to characterize the transmission loss of a partition. Time -weighted Average Sound Level Daily noise exposure normalized to an 8 -hour working day. US01070_Noise Study I May 2019 Page 7of15 wood Anadarko Johnstown Compressor Station Noise Assessment Report Report 2.0 Weld County Noise Standard The Weld County noise standard establishes permissible sound levels by the type of property for daytime (7:00 AM -9:00 PM) and night time (9:00 PM -7:00 AM) operational noise shown in Table 2.1. The measurement location is defined in Section 14-9-50-A.2. "A noise originating on private property shall be measured at or within the boundary of the property from which the noise complaint is made". Johnstown compressor station is located adjacent to a Non -specified area. According to the Weld County noise ordinance the noise level of the unspecified areas needs to meet the night-time noise limit of 50 dBA. Therefore, the noise limit for Johnstown compressor station is 50 dBA at the property line.

P.E. State of Colorado No. 45134 3rca(jI ;:on, Johnstown Compressor Station_Prellm Drainage Report June2018.docx IV PRELIMINARY DRAINAGE REPORT GENERAL LOCATION This Drainage Report is written to support the development of the Johnstown Compressor Station (site) by Kerr-McGee Gathering, LLC. a wholly owned subsidiary of Anadarko Petroleum Company (Anadarko). This report was prepared in accordance with Weld County requirements. The site is located in the southeast quarter of Section 18. Township 4 North. Range 67 West of the 6th Principal Meridian, Weld County, Colorado. The site is bounded on the south by Weld County Road 44 (WCR44) and on the east by WCR15. The current zoning is agricultural (Zone A). 1.1 1_ oca l Streets The site is bounded on the south by WCR44 and on the east by WCR15. as stated above. Both roads are currently classified as local roads. Proposed access is along WCR44, where the minimum spacing between access points is 150 feet. To access the facility Anadarko has proposed to construct a driveway to tie into the existing PDC Energy Access road, which is on the north side of WCR 44 approximately 2,610 feet west of WCR 15. The nearest existing access to the west of the site is approximately 1570 feet. 1.2 Adjacent Waterways Hillsborough Ditch exists south of the proposed compressor site (off -property). The Little Thompson River is approximately 2,200 feet north of the proposed compressor site. There are no immediately adjacent major ditches or waterways to the proposed site. 1.3 Adjacent Development Adjacent development consists of a single-family residence to the southeast and south of the proposed compressor site. There is an existing oil and gas facility to the southwest and southeast of the proposed compressor station. Adjacent land is used as agricultural purposes. arcadis.com Johnstown Compressor Station_Prelim Drainage Report_October2D18 1 PRELIMINARY DRAINAGE REPORT PROPERTY DESCRIPTION The proposed compressor site is located on agricultural land and will encompass approximately 12.9 acres of the 84.4 -acre parcel that is owned by Anadarko (see Figure 1). 2.1 Vegetation and Soil Information The land for the proposed compressor station is currently used for agricultural purposes. and as such. the vegetation consists of agricultural crops. The predominant soil according to the Natural Resource Conservation Service (NRCS) is Colombo clay loam at the surface, with a stratified -loam to clayey -loam from a depth of 14 to 21 inches. and a stratified sand to loam to clayey -loam to a depth of 60 inches. The soil is classified as Hydrologic Soil Group C. which is also characterized as a CL in the Unified Soil Classification System. The NRCS soils report for the site is provided as reference in Appendix A. Johnstown Compressor Station_Prelim Drainage Report_October2018 2 PRELIMINARY DRAINAGE REPORT PROJECT DESCRIPTION The proposed Johnstown compressor site would include new oil and gas equipment. an electrical transformer yard, and associated piping to assist in the compression of natural gas in a pipeline. Approximately 12.9 acres of the site will be used for the development. A proposed detention pond is included in the development site plan and has been designed to provide the 100 -year detention volume based on the requisite design criteria for Weld County. arcadis.com Johnstown Compressor Station_Prelim Drainage Report_october2018 3 PRELIMINARY DRAINAGE REPORT EXIS r"INCA DRAINAGE CONDITIONS This section describes the existing drainage conditions on the site. as well as drainage that is flowing on to the site. The property is located in the Big Thompson regional watershed: however. there are no known Weld County Master Drainage plans for the site. 4J Existing Drainage Basins In general. stormwater flows from the south to the north. ultimately reaching the Little Thompson River. which is approximately 150 feet north of the northern property boundary. The stormwater drainage from a regional high point from the south is intercepted by the Hillsborough Ditch, south of WCR 44, before it reaches the Anadarko property. Therefore, only property north of the ditch that is tributary to the overall basin flow, has been considered (see Figure 1). The subject property, including contributory offsite areas can be delineated into three basins across the property. These have been labeled Basins 001. 002, and 003 on Figure 1. The flow through each of these basins is predominantly from the northern side of the Hillsborough ditch. across WCR44 and northward, off the property and ultimately to the Little Thompson River. The slopes onsite for this flow vary, with steeper slopes toward the south and lesser slopes to the north and range from approximately 5.0% to 0.5%. The proposed compressor site is located entirely within Basin 002 and no proposed improvements for the compressor site fall outside the boundary of Basin 002: therefore. it is the only basin under consideration. 4.2 Federal Emergency Management Agency Flood Insurance Rate Map The Federal Emergency Management Agency, Flood Insurance Rate Map that covers the proposed compressor site is Map Number 08123C1695E, dated January 20, 2016. This map shows that the proposed site is in Other Areas. Zone X. which is "Areas determined to be outside the 0.2% chance annual flood plain" (see Figure 2). arcadis corn Johnstown Compressor Station_Prelim Drainage Report_october2018 4 PRELIMINARY DRAINAGE REPORT PROPOSED DRAINAGE CONDITIONS This section describes the proposed drainage conditions for Basin 001. No changes are proposed to Basin 003 on the property. Stormwater flow for those portions of Basin 002 that remain undisturbed will be diverted around the compressor station and allowed to follow their historical drainage path north and offsite. Stormwater from the compressor station will be diverted to a retention pond that is sized per Weld County standards. and adequate to contain the 100 -year event. Calculations are included in Appendix B. 5.1 Rainfall The design rainfall for the compressor station was obtained through National Oceanic and Atmospheric Administration (NOAA), Point Precipitation Frequency Data Server (PPFDS); the Urban Storm Drainage Criteria Manual Volume 1 (USDCM); and Weld County requirements. The proposed compressor station is outside of the Urban Drainage and Flood Control District (UDFCD) boundary, and the watershed area is less than 15 square miles in size. Therefore, the NOAA PPFDS data for a 1 -hour storm, with average recurrence intervals of 2. 5, 10. 25. 50. 100, and 500 years were used. A copy of the applicable NOAA PPFDS for this location is included in Appendix C. 5 2 Detention Weld County prefers and recommends the use of detention basins wherever possible in development projects within the county. Detention is provided for the compressor statin and an 8 -inch culvert is proposed to drain the detention basin to east releasing the water at a controlled rate into the remaining undisturbed portions of the agricultural field (Figure 3). The storm water sheet flows to the east and leaves the property via an existing culvert in the northeast corner of the property. The basin is required to detain 2.66 -acre-feet per the requirements in the USDCM. The USDCM calculations that were prepared using the UDFCD Detention Basin Design Workbook are provided in Appendix B. arcadis.com Johnstown Compressor Station_Prelim Drainage Repor,_Octabe2018 5 PRELIMINARY DRAINAGE REPORT REFERENCES Detention Basin Design Workbook.

State agencies including the Agricultural Experiment Stations. and local participants Custom Soil Resource Report for Weld County, Colorado, Southern Part June 13. 2018 Preface Soil surveys contain information that affects land use planning in survey areas. They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers. foresters, agronomists. urban planners. community officials, engineers, developers. builders, and home buyers. Also. conservationists, teachers, students. and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect. or enhance the environment. Various land use regulations of Federal. State. and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm. local. and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http_//www.nres.usda.gov/wps/ portal/nres/main/soils/health!) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https //offices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nres142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies. State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes: the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently. soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate. water resources, soils, biological resources, and land uses (USDA. 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology landforms, relief. climate. and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations. supplemented by an understanding of the soil -vegetation -landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture. size and shape of soil aggregates, kind and amount of rock fragments. distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties. the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States. is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil 5 Custom Soil Resource Report scientists classified and named the soils in the survey area. they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components, the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned. onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors. including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil -landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil -landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color. depth to bedrock, and texture. and laboratory measurements, such as those for content of sand; silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress. samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field -observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example. data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and 6 Custom Soil Resource Report identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. 7 Soil Map The soil map section includes the soil map for the defined area of interest. a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map.

The map unit descriptions. along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however. the soils are natural phenomena. and they have the characteristic variability of all natural phenomena. Thus. the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely. if ever. can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar. components. They may or may not be mentioned in a particular map unit description. Other minor components. however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting. or dissimilar. components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or 11 Custom Soil Resource Report landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer. all the soils of a series have major horizons that are similar in composition. thickness. and arrangement. Soils of one series can differ in texture of the surface layer, slope. stoniness. salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences. a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam. 0 to 2 percent slopes. is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations. or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha -Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas. or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 12 Custom Soil Resource Report Weld County, Colorado, Southern Part 19 Colombo clay loam, 0 to 1 percent slopes Map Unit Setting National map unit symbol: 361v Elevation: 4,600 to 4,780 feet Mean annual precipitation: 12 to 16 inches Mean annual air temperature: 48 to 52 degrees F Frost -free period: 130 to 160 days Farmland classification: Prime farmland if irrigated Map Unit Composition Colombo and similar soils: 85 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the mapunit.

A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each property or quality. Soil Qualities and Features Soil qualities are behavior and performance attributes that are not directly measured, but are inferred from observations of dynamic conditions and from soil properties. Example soil qualities include natural drainage, and frost action. Soil features are attributes that are not directly part of the soil. Example soil features include slope and depth to restrictive layer. These features can greatly impact the use and management of the soil. Hydrologic Soil Group (Johnstown Compressor Station) Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation. are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A. B. C. and D) and three dual classes (A/D, B/D. and C/D). The groups are defined as follows' Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep. moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. 18 Custom Soil Resource Report Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table. soils that have a claypan or clay layer at or near the surface. and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (ND. B/D, or C/D). the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. 19 :0' IS 39'. 8 V 40° 18'19'N b A Custom Soil Resource Report Map —Hydrologic Soil Group (Johnstown Compressor Station) ‘,.-i06C1 P iniliainneasto Soil Map may n t be valid" I I I Map Scale: 1:4,450 it pnnteed on A landscape (11" x 8.S') sheet. k N o 50 1(X) 200 et N o zoo 409 eoo 1200 Map projection: Web Mercator Corner coordinates: WGS84 Edge tics: UTM Zone 13N WGS84 5930:0 Meters 5C61Ce 593190 20 `Sraaf00 5033:0 5:340° 503600 104° 5519' W 509300 Stoat° 114 40° 18'39'N 40° 18'19'N Custom Soil Resource Report MAP LEGEND MAP INFORMATION Area of interest (AOl) Area of Interest (AO') Soils Soil Rating Polygons A ND B B/D C C/D D Not rated or not available Soil Rating Lines A ^/ A/D ti r 0 B B/D C "00 C/D aka.

According to this system, soil is classified into seven major groups: A -I through A-7. Soils classified into groups A-1. A-2. and A-3 are granular materials of which 35% or less of the particles pass through the No. 200 sieve. Soils of which more than 35% pass through the No. 200 sieve are classified into groups A-4. A-5, A-6, and A-7. These soils are mostly silt and clay -type materials. The classifications system is based on the following criteria: 1. Grain size a. Gravel : fraction passing the 75 -mm( 3 -in.) sieve and retained on the No. 10 (2 - mm) U.S. sieve b. sand: fraction passing the No. 10 (2 -mm) U.S. sieve and retained on the No.200 (0.075 -mm) U.S. sieve c. Silt and clay: fraction passing the No. 200 U.S. sieve 22 Custom Soil Resource Report 2. Plasticity The term silty is applied when the fine fractions of the soil have a plasticity index of 10 or less. The term clayey is applied when the fine fractions have a plasticity index of 11 or more. 3. If cobbles and boulders (size larger than 75 mm) are encountered. they are excluded from the portion of the soil sample from which classification is made. To evaluate the quality of a soil as a highway subgrade material, one must also incorporate a number called the group index (GI) with the groups and subgroups of the soil. This index is written in parentheses after the group or subgroup designation. The group index is given by the equation: GI = (F200-35)[0.2+ 0.005(LL- 40)] + 0.01(.F200-15)(PI- 10) where: F200 = percentage passing through the No. 200 sieve LL — liquid limit PI plasticity index The group index is used typically to refine an AASHTO class but in the soil survey database is often used as a standalone soil attribute. For each soil layer. this attribute is actually recorded as three separate values in the database. A low value and a high value indicate the range of this attribute for the soil component. A "representative" value indicates the expected value of this attribute for the component. For this soil property. only the representative value is used. 23 b ° 40° 18' 39" N 40° 18'19"N Map Scale 1:4,450 if pnnted on A landscape (11" x8.5") sheet A Custom Soil Resource Report Map—AASHTO Group Index (Johnstown Compressor Station) 5359:0 0 50 100 200 Meters 300 Feet 0 200 400 800 1200 Map projection: Web Mercator Corner coordinates: WGS84 Edge tics: UTM Zone 13N WGS84 24 We 55 IT W 40° 18' 39" N 40° IK 19' N Custom Soil Resource Report Area of Interest (AOI) El MAP LEGEND Area of Interest (AOI) Solis Soil Rating Polygons <= 2 u > 2and <=3 > 3and <=5 Not rated or not available Soil Rating Lines �,<.. = 2 >2and <=3 > 3and <=5 Not rated or not available Soil Rating Points <=2 ❑ >2and <=3 > 3 and <= 5 Not rated or not available • O Water Features Streams and Canals Transportation r -+-a Rails Interstate Highways US Routes Major Roads Local Roads Background Olt Aerial Photography 25 MAP INFORMATION The soil surveys that comprise your AOI were mapped at 1:24,000.

It identifies three major soil divisions: (i) coarse -grained soils having less than 50 percent. by weight, particles smaller than 0.074 mm in diameter (ii) fine-grained soils having 50 percent or more. by weight, particles smaller than 0.074 mm in diameter: and (iii) highly organic soils that demonstrate certain organic characteristics. These divisions are further subdivided into a total of 15 basic soil groups. The major soil divisions and basic soil groups are determined on the basis of estimated or measured values for grain -size distribution and Atterberg limits. ASTM D 2487 shows the criteria chart used for classifying soil in the Unified system and the 15 basic soil groups of the system and the plasticity chart for the Unified system. The various groupings of this classification correlate in a general way with the engineering behavior of soils. This correlation provides a useful first step in any field or laboratory investigation for engineering purposes. It can serve to make some general interpretations relating to probable performance of the soil for engineering uses. 30 Custom Soil Resource Report For each soil horizon in the database one or more Unified soil classifications may be listed. One is marked as the representative or most commonly occurring.

ABC soil A soil having an A. a B. and a C horizon. Ablation till Loose, relatively permeable earthy material deposited during the downwasting of nearly static glacial ice, either contained within or accumulated on the surface of the glacier. AC soil A soil having only an A and a C horizon. Commonly, such soil formed in recent alluvium or on steep. rocky slopes. Aeration, soil The exchange of air in soil with air from the atmosphere. The air in a well aerated soil is similar to that in the atmosphere: the air in a poorly aerated soil is considerably higher in carbon dioxide and lower in oxygen. Aggregate, soil Many fine particles held in a single mass or cluster. Natural soil aggregates, such as granules. blocks. or prisms. are called peds. Clods are aggregates produced by tillage or logging. Alkali (sodic) soil A soil having so high a degree of alkalinity (pH 8.5 or higher) or so high a percentage of exchangeable sodium (15 percent or more of the total exchangeable bases). or both. that plant growth is restricted. Alluvial cone A semiconical type of alluvial fan having very steep slopes. It is higher. narrower, and steeper than a fan and is composed of coarser and thicker layers of material deposited by a combination of alluvial episodes and (to a much lesser degree) landslides (debris flow). The coarsest materials tend to be concentrated at the apex of the cone. 38 Custom Soil Resource Report Alluvial fan A low, outspread mass of loose materials and/or rock material, commonly with gentle slopes. It is shaped like an open fan or a segment of a cone. The material was deposited by a stream at the place where it issues from a narrow mountain valley or upland valley or where a tributary stream is near or at its junction with the main stream. The fan is steepest near its apex. which points upstream, and slopes gently and convexly outward (downstream) with a gradual decrease in gradient. Alluvium Unconsolidated material, such as gravel. sand. silt. clay, and various mixtures of these. deposited on land by running water. Alpha,alpha-dipyridyl A compound that when dissolved in ammonium acetate is used to detect the presence of reduced iron (Fe II) in the soil. A positive reaction implies reducing conditions and the likely presence of redoximorphic features. Animal unit month (AUM) The amount of forage required by one mature cow of approximately 1.000 pounds weight, with or without a calf. for 1 month. Aquic conditions Current soil wetness characterized by saturation. reduction. and redoximorphic features. Argillic horizon A subsoil horizon characterized by an accumulation of illuvial clay. Arroyo The flat -floored channel of an ephemeral stream, commonly with very steep to vertical banks cut in unconsolidated material. It is usually dry but can be transformed into a temporary watercourse or short-lived torrent after heavy rain within the watershed. Aspect The direction toward which a slope faces. Also called slope aspect. Association, soil A group of soils or miscellaneous areas geographically associated in a characteristic repeating pattern and defined and delineated as a single map unit. Available water capacity (available moisture capacity) The capacity of soils to hold water available for use by most plants. It is commonly defined as the difference between the amount of soil water at field moisture capacity and the amount at wilting point. It is commonly expressed as inches of water per inch of soil. The capacity. in inches, in a 60 -inch profile or to a limiting layer is expressed as: 39 Custom Soil Resource Report Very low: 0 to 3 Low: 3 to 6 Moderate: 6 to 9 High: 9 to 12 Very high: More than 12 Backslope The position that forms the steepest and generally linear, middle portion of a hillslope. In profile. backslopes are commonly bounded by a convex shoulder above and a concave footslope below. Backswamp A flood -plain landform. Extensive, marshy or swampy, depressed areas of flood plains between natural levees and valley sides or terraces. Badland A landscape that is intricately dissected and characterized by a very fine drainage network with high drainage densities and short, steep slopes and narrow interfluves. Badlands develop on surfaces that have little or no vegetative cover overlying unconsolidated or poorly cemented materials (clays. silts, or sandstones) with. in some cases. soluble minerals; such as gypsum or halite. Bajada A broad, gently inclined alluvial piedmont slope extending from the base of a mountain range out into a basin and formed by the lateral coalescence of a series of alluvial fans. Typically, it has a broadly undulating transverse profile, parallel to the mountain front, resulting from the convexities of component fans.

In a good conservation cropping system. the soil -improving crops and practices more than offset the effects of the soil -depleting crops and practices. Cropping systems are needed on all tilled soils. Soil -improving practices in a conservation cropping system include the use of rotations that contain grasses and legumes and the return of crop residue to the soil. Other practices include the use of green manure crops of grasses and legumes. proper tillage, adequate fertilization. and weed and pest control.

Diversion (or diversion terrace) A ridge of earth, generally a terrace. built to protect downslope areas by diverting runoff from its natural course. Divided -slope farming A form of field striperopping in which crops are grown in a systematic arrangement of two strips, or bands, across the slope to reduce the hazard of water erosion. One strip is in a close -growing crop that provides protection from erosion. and the other strip is in a crop that provides less protection from erosion. This practice is used where slopes are not long enough to permit a full striperopping pattern to be used. Drainage class (natural) Refers to the frequency and duration of wet periods under conditions similar to those under which the soil formed. Alterations of the water regime by human activities, either through drainage or irrigation. are not a consideration unless they have significantly changed the morphology of the soil. Seven classes of natural soil drainage are recognized —excessively drained, somewhat excessively drained, well drained, moderately well drained, somewhat poorly drained, poorly drained. and very poorly drained. These classes are defined in the "Soil Survey Manual." Drainage, surface Runoff, or surface flow of water, from an area.

Drumlins are products of streamline (laminar) flow of glaciers, which molded the subglacial floor through a combination of erosion and deposition. Duff A generally firm organic layer on the surface of mineral soils. It consists of fallen plant material that is in the process of decomposition and includes everything from the litter on the surface to underlying pure humus.

An ecological site is the product of all the environmental factors responsible for its development. It is typified by an association of species that differ from those on other ecological sites in kind and/or proportion of species or in total production. Eluviation The movement of material in true solution or colloidal suspension from one place to another within the soil. Soil horizons that have lost material through eluviation are eluvial: those that have received material are illuvial.

Hillslope A generic term for the steeper part of a hill between its summit and the drainage line. valley flat, or depression floor at the base of a hill. Horizon, soil A layer of soil, approximately parallel to the surface. having distinct characteristics produced by soil -forming processes. In the identification of soil horizons, an uppercase letter represents the major horizons. Numbers or lowercase letters that follow represent subdivisions of the major horizons. An explanation of the subdivisions is given in the "Soil Survey Manual." The major horizons of mineral soil are as follows: 55 Custom Soil Resource Report O horizon: An organic layer of fresh and decaying plant residue. L horizon: A layer of organic and mineral limnic materials. including coprogenous earth (sedimentary peat), diatomaceous earth, and marl. A horizon: The mineral horizon at or near the surface in which an accumulation of humified organic matter is mixed with the mineral material. Also. a plowed surface horizon, most of which was originally part of a B horizon. E horizon: The mineral horizon in which the main feature is loss of silicate clay. iron. aluminum, or some combination of these. B horizon: The mineral horizon below an A horizon. The B horizon is in part a layer of transition from the overlying A to the underlying C horizon. The B horizon also has distinctive characteristics. such as (1) accumulation of clay, sesquioxides, humus. or a combination of these: (2) prismatic or blocky structure; (3) redder or browner colors than those in the A horizon, or (4) a combination of these. C horizon: The mineral horizon or layer, excluding indurated bedrock. that is little affected by soil -forming processes and does not have the properties typical of the overlying soil material. The material of a C horizon may be either like or unlike that in which the solum formed. If the material is known to differ from that in the solum, an Arabic numeral, commonly a 2, precedes the letter C. Cr horizon: Soft, consolidated bedrock beneath the soil. R layer Consolidated bedrock beneath the soil. The bedrock commonly underlies a C horizon., but it can be directly below an A or a B horizon. M layer A root -limiting subsoil layer consisting of nearly continuous, horizontally oriented, human -manufactured materials. W layer: A layer of water within or beneath the soil. Humus The well decomposed. more or less stable part of the organic matter in mineral soils. Hydrologic soil groups Refers to soils grouped according to their runoff potential. The soil properties that influence this potential are those that affect the minimum rate of water infiltration on a bare soil during periods after prolonged wetting when the soil is not frozen. These properties include depth to a seasonal high water table, the infiltration rate, and depth to a layer that significantly restricts the downward movement of water. The slope and the kind of plant cover are not considered but are separate factors in predicting runoff. Igneous rock Rock that was formed by cooling and solidification of magma and that has not been changed appreciably by weathering since its formation. Major varieties include plutonic and volcanic rock (e.g., andesite, basalt, and granite). Illuviation The movement of soil material from one horizon to another in the soil profile. Generally, material is removed from an upper horizon and deposited in a lower horizon. 56 Custom Soil Resource Report Impervious soil A soil through which water air, or roots penetrate slowly or not at all. No soil is absolutely impervious to air and water all the time. Increasers Species in the climax vegetation that increase in amount as the more desirable plants are reduced by close grazing. Increasers commonly are the shorter plants and the less palatable to livestock. Infiltration The downward entry of water into the immediate surface of soil or other material, as contrasted with percolation, which is movement of water through soil layers or material. Infiltration capacity The maximum rate at which water can infiltrate into a soil under a given set of conditions. Infiltration rate The rate at which water penetrates the surface of the soil at any given instant, usually expressed in inches per hour. The rate can be limited by the infiltration capacity of the soil or the rate at which water is applied at the surface. Intake rate The average rate of water entering the soil under irrigation. Most soils have a fast initial rate; the rate decreases with application time. Therefore. intake rate for design purposes is not a constant but is a variable depending on the net irrigation application. The rate of water intakein inches per hour. is expressed as follows: Very low: Less than 0.2 Low: 0.2 to 0.4 Moderately low: 0.4 to 0.75 Moderate: 0.75 to 1.25 Moderately high: 1.25 to 1.75 High: 1.75 to 2.5 Very high: More than 2.5 Interfluve A landform composed of the relatively undissected upland or ridge between two adjacent valleys containing streams flowing in the same general direction. An elevated area between two drainageways that sheds water to those drainageways. Interfluve (geomorphology) A geomorphic component of hills consisting of the uppermost. comparatively level or gently sloping area of a hill: shoulders of backwearing hillslopes can narrow the upland or can merge.. resulting in a strongly convex shape. 57 Custom Soil Resource Report Intermittent stream A stream, or reach of a stream, that does not flow year-round but that is commonly dry for 3 or more months out of 12 and whose channel is generally below the local water table. It flows only during wet periods or when it receives ground -water discharge or long, continued contributions from melting snow or other surface and shallow subsurface sources. Invaders On range, plants that encroach into an area and grow after the climax vegetation has been reduced by grazing. Generally, plants invade following disturbance of the surface. Iron depletions See Redoximorphic features. Irrigation Application of water to soils to assist in production of crops. Methods of irrigation are: Basin: Water is applied rapidly to nearly level plains surrounded by levees or dikes. Border Water is applied at the upper end of a strip in which the lateral flow of water is controlled by small earth ridges called border dikes, or borders. Controlled flooding: Water is released at intervals from closely spaced field ditches and distributed uniformly over the field. Corrugation: Water is applied to small, closely spaced furrows or ditches in fields of close -growing crops or in orchards so that it flows in only one direction. Drip (or trickle). Water is applied slowly and under low pressure to the surface of the soil or into the soil through such applicators as emitters, porous tubing. or perforated pipe. Furrow: Water is applied in small ditches made by cultivation implements. Furrows are used for tree and row crops. Sprinkler Water is sprayed over the soil surface through pipes or nozzles from a pressure system.

The term is usually applied both to the relatively flat summit surface (tread) that was cut or built by stream or wave action and to the steeper descending slope (scarp or riser) that has graded to a lower base level of erosion. Terracettes Small, irregular steplike forms on steep hillslopes, especially in pasture, formed by creep or erosion of surficial materials that may be induced or enhanced by trampling of livestock. such as sheep or cattle. Texture, soil The relative proportions of sand, silt, and clay particles in a mass of soil. The basic textural classes. in order of increasing proportion of fine particles, are sand, loamy sand, sandy loam, loam, silt loam. silt, sandy clay loam, clay loam, silty clay loam, sandy clay, silty c/ay, and clay. The sand, loamy sand, and sandy loam classes may be further divided by specifying -coarse." "fine," or "very fine." Thin layer Otherwise suitable soil material that is too thin for the specified use. Till Dominantly unsorted and nonstratified drift, generally unconsolidated and deposited directly by a glacier without subsequent reworking by meltwater, and consisting of a heterogeneous mixture of clay. silt, sand, gravel. stones, and boulders: rock fragments of various lithologies are embedded within a finer matrix that can range from clay to sandy loam. Till plain An extensive area of level to gently undulating soils underlain predominantly by till and bounded at the distal end by subordinate recessional or end moraines. Tilth, soil The physical condition of the soil as related to tillage, seedbed preparation, seedling emergence, and root penetration. Toeslope The gently inclined surface at the base of a hillslope. Toeslopes in profile are commonly gentle and linear and are constructional surfaces forming the lower part of a hillslope continuum that grades to valley or closed -depression floors. 77 Custom Soil Resource Report Topsoil The upper part of the soil, which is the most favorable material for plant growth. It is ordinarily rich in organic matter and is used to topdress roadbanks, lawns, and land affected by mining. Trace elements Chemical elements. for example, zinc, cobalt. manganese. copper. and iron, in soils in extremely small amounts. They are essential to plant growth. Tread The flat to gently sloping, topmost, laterally extensive slope of terraces, flood - plain steps, or other stepped landforms; commonly a recurring part of a series of natural steplike landforms, such as successive stream terraces. Tuff A generic term for any consolidated or cemented deposit that is 50 percent or more volcanic ash. Upland An informal, general term for the higher ground of a region, in contrast with a low-lying adjacent area, such as a valley or plain, or for land at a higher elevation than the flood plain or low stream terrace; land above the footslope zone of the hillslope continuum. Valley fill The unconsolidated sediment deposited by any agent (water, wind. ice, or mass wasting) so as to fill or partly fill a valley. Variegation Refers to patterns of contrasting colors assumed to be inherited from the parent material rather than to be the result of poor drainage. Varve A sedimentary layer or a lamina or sequence of laminae deposited in a body of still water within a year. Specifically, a thin pair of graded glaciolacustrine layers seasonally deposited. usually by meltwater streams, in a glacial lake or other body of still water in front of a glacier. Very stony spot (map symbol) A spot where 0.1 to 3.0 percent of the soil surface is covered by rock fragments that are more than 10 inches in diameter in areas where the surface of the surrounding soil is covered by less than 0.01 percent stones. Water bars Smooth, shallow ditches or depressional areas that are excavated at an angle across a sloping road. They are used to reduce the downward velocity of water and divert it off and away from the road surface. Water bars can easily be driven over if constructed properly. 78 Custom Soil Resource Report Weathering All physical disintegration. chemical decomposition, and biologically induced changes in rocks or other deposits at or near the earth's surface by atmospheric or biologic agents or by circulating surface waters but involving essentially no transport of the altered material. Well graded Refers to soil material consisting of coarse grained particles that are well distributed over a wide range in size or diameter. Such soil normally can be easily increased in density and bearing properties by compaction. Contrasts with poorly graded soil. Wet spot (map symbol) A somewhat poorly drained to very poorly drained area that is at least two drainage classes wetter than the named soils in the surrounding map unit. Wilting point (or permanent wilting point) The moisture content of soil. on an ovendry basis, at which a plant (specifically a sunflower) wilts so much that it does not recover when placed in a humid, dark chamber. Windthrow The uprooting and tipping over of trees by the wind. 79 APPENDIX B Stormwater Detention Basin Calculations DETENTION BASIN STAGE -STORAGE TABLE BUILDER UD-Detentlon, Version 3.07 (February 20171 Project: Basin 10: scent • :o• _. ems •1 : tr. ecsesa row , setts Tweet fins...

The drainage design shall meet the requirements of the Weld County Code and commonly accepted engineering practices and methodologies. A detention pond design (or other stormwater mitigation design) is appropriate for projects which have a potential to adversely affect downstream neighbors and public rights -of -way from changes in stormwater runoff as a result of the development project. The design engineer's role is to ensure adjacent property owners are not adversely affected by stormwater runoff created by development of the applicant's property.

The County requires detention ponds in the Urbanizing area to be sized using the historic (2% impervious) 5 - year runoff value as the pond release rate during the 100 -year. 1 -hour storm event. a. A full spectrum pond design does not follow this standard (100 -year historic release during the 100 -year storm). so the method is not accepted by the County. b. The County does require the WQCV be contained and released within a 40 -hour time period. The WQCV may be included within the overall detention volume. 4/11/2018 Weld County Department of Public Works/ Development Review 1111 H Street. Greeley.

The Urban Drainage "UD-Detention_v3.07" spreadsheet can be used for the design, considering the following: i. The Routed Hydrograph method be used to size the detention volume. This information is found at the bottom of the "Outlet Structure" tab. ii. The final volume for the pond should be taken from the "Maximum Volume Stored- under the Routed Hydrograph Results section for the 100 -year event. iii. The "Peak Outflow Q (cfs)" for the 100 -year event should match the historic 10 -year release rate allowed. iv. The peak outflow value is adjusted by modifying the circular orifice, restrictor plate or rectangular orifice values located in the User Input section of the "Outlet Structure" tab. d. Other pond sizing methods are acceptable, such as the Modified FAA method. 2. Please provide imperviousness calculations. All historic basins should be modeled using 2% imperviousness. When calculating the weighted C value for the proposed site. please model the pond water surface area using a 100% impervious value. 3. Include the off -site runoff calculations used to design the swales around the site. 4. Include the historical 5 -year, 1 -hour runoff rates calculated. 5. Include time of concentration calculations. 6. Include outlet and spillway design calculations and details in the drawings. The spillway shall be designed to comply with the code section 23-12-90.A.6 & 7. The outlet shall be designed to comply with code sections 23- 12-90.A.5. 7. Page 5, Section 5 of the drainage report says the pond is a retention pond. Retention facilities are not allowed in Weld County without the issuance of a variance. If proposed. a retention pond must comply with section 23- 12-30.B of the Weld County Code. 8. A 12" outlet pipe is required on the pond outlet. 9. Once the revised design and drainage report have been submitted, the County may provide additional comments in addition to the ones listed above. Depending on the complexity of the changes made, a full 28 -day review period may be required. 10. Please provide a written response on how the above comments have been addressed when resubmitting the drainage report.

Only 4 residents inquired about the Compressor Station. We took the feedback gathered from these inquiries and agreed to share an access with PDC Energy so traffic during construction would not be routed in front of the residence located at 6604 COUNTY ROAD 44. Additionally we are proposing a masonry wall along the southern boundary of the facility to help provide visual screening and some noise mitigation. If you have any questions, please contact Nathan Keiser, Regulatory Analyst, Anadarko Petroleum Corporation at 720-929-6896 or Nathan.keiser@anadarko.com. MEMO ARCADIS Nathan Keiser Municipal Planning Analyst Anadarko Petroleum Corporation Bill Zahniser. P.E. Copies: File Date Arcadis Project No July 2, 2018 CO002330.0001.00002 Subject Anticipated Traffic Summary for the Johnstown Compressor Station Weld County, Colorado; USR 18-0125 Arcadis U.S., Inc. 630 Plaza Dnve Suite 100 Highlands Ranch Colorado 80129 Tel 720 344 3500 Fax 720 344 3535 Design & Consultancy for natural and built assets Anadarko Petroleum Corporation (Anadarko) is proposing construction of a new compressor station. near the intersection of Weld County Road (WCR) 15 and WCR 44. within the A (Agricultural) Zone District of Weld County. Colorado. This memorandum provides a summary of the traffic expectations associated with the development of the facility during the construction and operation phases. Based on our review of these numbers and Weld County requirements we do not anticipate a formal traffic study is warranted. AREA OF INTEREST The legal description for the property is Lot B RE -1228; which includes a portion of the Southeast Quarter of Section 18. Township 4 North, Range 67 West of the 6th Prime Meridian. and is currently considered unincorporated Weld County. To access the facility. Anadarko will construct a driveway to tie into the existing PDC Energy access road, which is on the north side of WCR 44 approximately 2,610 feet west of WCR 15. WCR 44. between WCR 13 and WCR 15 is currently a partially improved gravel roadway. that is classified by Weld County as a local road. TRIP GENERATION ESTIMATES Trip generation estimates for this development can be characterized as either construction phase (temporary) traffic and operations phase (future/permanent) traffic. A summary of the anticipated temporary traffic for the construction of this facility is provided in Attachment 1. The construction phase has been further broken down into two types of construction activity. which will be performed in a sequential (not concurrent manner). Below is an overview of the estimated duration. total vehicle numbers \\arcades-us.com\OfirceData\Denver-CO-Technical\Aprotect\Anadarko\Compressor Station SrteslJormstown CS\Traffic Memo\Traffic Summary Memo.docx Page. 1/2 MEMO per day. and peak hour traffic trips anticipated for the various phases of construction. as well as the ensuing operation of the facility. Construction Phase (Temporary) Traffic Expectations 1. Site Preparation and Grading a. Duration- 30 days b. Average Vehicles per Day: 41 Vehicles. 100 Passenger Car Equivalents (PCE) c. Number of AM/PM Peak Hour Trips: 13 Vehicles. 25 PCE 2. Mechanical & Electrical Construction a. Duration: 90 days b. Average Vehicles per Day: 100 Vehicles, 152 PCE c. Number of AM/PM Peak Hour Trips: 58 Vehicles. 72 PCE Operations Phase (Permanent) Traffic Expectations Once operational. anticipated traffic will be minimal, as the facility will be unmanned and only require a daily site visit by an operator for facility management and maintenance considerations. Routine daily activities will generally consist of a single pickup truck per day. Occasionally this will decrease or increase. depending on the type of maintenance activity, but any increase will be below the level expected during construction, and will likely be short lived (i.e., for a couple of days at a time). TRAFFIC STUDY CONSIDERATIONS Arcadis reviewed whether the anticipated development traffic would require a traffic study. Based on our review of the trip generation estimates (summarized above) and the Weld County Transportation Impact Study Standards it does not appear that a traffic study is warranted. Our conclusion that a traffic study is not necessary is based on the following: • There is no zoning change being requested to accommodate the siting of this facility. • According to the Weld County Public Works Transportation Impact Study Technical Completeness Checklist. traffic studies are typically only required when the anticipated trip generation is expected to exceed two hundred (200) vehicles per day. • The greatest increase in traffic will occur during the relatively shod -lived period (90 days) of mechanical and electrical construction. The maximum AM and PM peak hour trips during this time will be 58 vehicles. or 72 PCE. and the maximum average number of vehicles per day will be 100, which is below the traffic study threshold number (200) established in the Completeness Checklist of the County standards. • The number of vehicles that will visit the facility once it is operational will average out to approximately one vehicle per day, and many of these daily visits will occur during off-peak hour periods. No baseline counts were available but given the nominal amount of traffic anticipated once the facility is operational. traffic generated during operation of this facility is not likely to increase traffic intensities or have any substantive impact on the existing level of service. along WCR 15 or WCR 44. arcadis.cun 11arcadis-us.com\OfficeData\Denver-CO-TechnicaMprojectlAnadarko\Compressor Station SitesUohnstown CS\Traffic Memo\Traffic Summary Memo.docx Page 2/2 41J KerrlVrGee Kerr-McGee Gathering LLC Y.O.

It should be used with the Caterpillar Fuel Usage Guide for the engine and rating to determine the rating (or the fuel specified. A Fuel Usage Guide for each rating is included on page 2 of its standard technical data sheet. RPC always applies to naturally aspirated (NA) engines, and turbocharged (TA or LE) engines only when they are derated for altitude and ambient site conditions. Project specific technical data sheets generated by the Caterpillar Gas Engine Rating Pro program take the Caterpillar Methane Number and RPC into account when generating a site rating. Fuel properties for Btu/sc( calculations are at 60F and 14.696 psia. Caterpillar shall have no liability in law or equity, for damages, consequently or otherwise, arising from use of program and related material or any part thereof. FUEL LIQUIDS Field gases, well head gases, and associated gases typically contain liquid water and heavy hydrocarbons entrained In the gas. To prevent detonation and severe damage to the engine, hydrocarbon liquids must not be allowed to enter the engine fuel system. To remove liquids, a liquid separator and coalescing filter are recommended, with an automatic drain and collection tank to prevent contamination of the ground in accordance with local codes and standards. To avoid water condensation in the engine or fuel lines, limit the relative humidity of water in the fuel to 80% at the minimum fuel operating temperature.

Danger! Poison! May be fatal or cause blindness if swallowed. Vapor harmful. Flammable liquid and vapor. Harmful if swallowed, inhaled, or absorbed through the skin. Causes eye, skin, and respiratory tract irritation. May cause central nervous system depression. Cannot be made non-poisonous. Target Organs: Eyes, nervous system, optic nerve. Potential Health Effects Eye: May cause painful sensitization to light. Methanol is a mild to moderate eye irritant. inhalation, ingestion or skin absorption of methanol can cause significant disturbance in vision, including blindness. Skin: Causes moderate skin irritation. May be absorbed through the skin in harmful amounts. Prolonged and or repeated contact may cause defatting of skin and dermatitis. Methanol can be absorbed through the skin, producing systemic effects that include visual disturbances. Ingestion: May be fatal or cause blindness if swallowed. Aspiration hazard. Cannot be made non- poisonous. May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause systematic toxicity with acidosis. May cause central nervous system depression, characterized by excitement, followed by headache, dizziness, drowsiness, and nausea. Advanced stages may cause collapse, unconsciousness, coma, and possible death due to failed respiratory failure. May cause cardiopulmonary system effects. Microbial ID Chemicals 1 MSDS Potassium Hydroxide Solution Material Safety Data Sheet Instant FAME/Instant Anaerobe Methods Methanol Inhalation: Methanol is toxic and can very readily form extremely high vapor concentrations at room temperature. Inhalation is the most common route of occupational exposure. At first, methanol causes CNS depression with nausea, headache, vomiting, dizziness and incoordination. A time period with no obvious symptoms follows (typically 8-24 hrs). This latent period is followed by metabolic acidosis and severe visual effects which may include reduced reactivity and/or increased sensitivity to light, blurred, doubl and/or snowy vision, and blindness. Depending on the severity of exposure and the promptness of treatment, survivors may recover completely or may have permanent blindness, vision disturbances and/or nervous system effects. Chronic: Prolonged or repeated skin contact may cause dermatitis. Chronic exposure may cause effects similar to those of acute exposure. Methanol is only very slowly eliminated from the body. Because of this slow elimination, methanol should be regarded as a cumulative poison. Though a single exposure may cause no effect, daily exposures may result in the accumulation of a harmful amount. Methanol has produced fetotoxicity in rats and teratogenicity in mice exposed by inhalation to high concentrations that did not produce significant maternal toxicity. SECTION 4 - FIRST AID MEASURES Eyes: In case of contact, immediately flush eyes with plenty of water for a t least 15 minutes. Get medical aid. Skin: In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid immediately. Wash clothing before reuse. Ingestion: Potential for aspiration if swallowed. Get medical aid immediately. Do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. If vomiting occurs naturally, have victim lean forward. Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. Notes to Physician: Effects may be delayed. Antidote: Ethanol may inhibit methanol metabolism. SECTION 5 - FIRE FIGHTING MEASURES General Information: Ethanol may inhibit methanol metabolism. As in any fire, wear a self-contained breathing apparatus in pressure -demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire -exposed containers cool. Water may be ineffective. Material is lighter than water and a fire may be spread by the use of water. Vapors are heavier than air and may travel to a source of ignition and flash back. Vapors can spread along the ground and collect in low or confined areas. Extinguishing Media: For small fires, use dry chemical, carbon dioxide, water spray or alcohol -resistant foam. Water may be ineffective. For large fires, use water spray, fog or alcohol -resistant foam. Do NOT use straight streams of water.

Spills/Leaks: Use water spray to disperse the gas/vapor. Remove all sources of ignition. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Do not use combustible materials such as sawdust. Use a spark -proof tool. Provide ventilation. A vapor suppressing foam may be used to reduce vapors. Water spray may reduce vapor but may not prevent ignition in closed spaces. Microbial ID Chemicals 2 MSDS Potassium Hydroxide Solution Material Safety Data Sheet Instant FAME/Instant Anaerobe Methods Methanol SECTION 7 -HANDLING AND STORAGE Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Ground and bond containers when transferring material. Use spark -proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Do not ingest or inhale. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Use only with adequate ventilation. Keep away from heat, sparks and flame. Avoid use in confined spaces. Storage: Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a cool, dry, well -ventilated area away from incompatible substances. Flammables-area. Keep containers tightly closed. SECTION 8 -- EXPOSURE CONTROL/ PERSONALS PROTECTION Engineering Controls: Use explosion -proof ventilation equipment. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.

Revision Number: 0 of Revision Date: 02/10/2003 Catr® NGECTM (Natural Gas Engine Coolant) Premix 50/50 MSDS : 11116 { ADDITIONAL TOXICOLOGY INFORMATION: This product contains ethylene glycol (EG). The toxicity of EG via inhalation or skin contact is expected to be slight at room temperature. The estimated oral lethal dose is about 100 cc (3.3 oz.) for an adult human. Ethylene glycol is oxidized to oxalic acid which results in the deposition of calcium oxalate crystals mainly in the brain and kidneys. Early signs and symptoms of EG poisoning may resemble those of alcohol intoxication. Later, the victim may experience nausea, vomiting, weakness, abdominal and muscle pain, difficulty in breathing and decreased urine output. When EG was heated above the boiling point of water, vapors formed which reportedly caused unconsciousness, increased lymphocyte count, and a rapid, jerky movement of the eyes in persons chronically exposed. When EG was administered orally to pregnant rats and mice, there was an increase in fetal deaths and birth defects. Some of these effects occurred at doses that had no toxic effects on the mothers. We are not aware of any reports that EG causes reproductive toxicity in human beings. This product contains diethylene glycol (DEG). The estimated oral lethal dose is about 50 cc (1.6 oz) for an adult human. DEG has caused the following effects in laboratory animals: liver abnormalities, kidney damage and blood abnormalities. It has been suggested as a cause of the following effects in humans: liver abnormalities, kidney damage, lung damage and central nervous system damage. SECTION 12 ECOLOGICAL INFORMATION ECOTOXICITY The toxicity of this material to aquatic organisms has not been evaluated. Consequently, this material should be kept out of sewage and drainage systems and all bodies of water. ENVIRONMENTAL FATE This material is expected to be readily biodegradable. SECTION 13 DISPOSAL CONSIDERATIONS Use material for its intended purpose or recycle if possible. This material, if it must be discarded, may meet the criteria of a hazardous waste as defined by US EPA under RCRA (40 CFR 261) or other State and local regulations. Measurement of certain physical properties and analysis for regulated components may be necessary to make a correct determination. If this material is classified as a hazardous waste, federal law requires disposal at a licensed hazardous waste disposal facility.

Do not click links or open attachments unless you recognize the sender and know the content is safe Good morning Tisa, I was able to confirm our haul route for the proposed Johnstown Compressor Station. Based on feedback from our selected vendors and where the construction material is coming from, we will utilize two primary haul routes. The bulk of material needed to build construct the pad location will be utilizing WCR 13 to WCR 44 and then east to our proposed location. The remainder of the material (road base), will be coming from 1-25 to WCR 44, and then east to our location. Do you foresee any issues with this routing? Both of these routes utilize paved roads to within %: mile of our facility. The last half mile is unpaved and dust suppression applied to minimize impact during construction. Also, we agreed to share an access with PDC Energy to avoid having traffic drive past the resident to the south of the facility. Any feedback would be appreciated.

Ultimately it will be a combination of gas and electric, but permitting as gas gives us more flexibility to switch to gas if needed. Hopefully this all makes sense. Also, we'll still continue to be able to operate at residential noise standards, and the type of compressor won't impact our overall noise. Thanks for getting things set up and give me a call if we need to discuss the gas vs. electric.

I am setting aside time to set your case up tomorrow. One thing — can you indicate the types of compressor (gas vs. electrical).

We are fine installing at 35' tower for this location and don't need the typical 70' height. This should be sufficient to have the project set up and get it moving right? I'm pretty happy with this news! Thanks and let me know what my next steps should be. Have a good morning.

The only item I would like addressed immediately are items #2 and #3. Item #1 should be provided during the 28 -day referral period. Item #4 is more of an advisement vs. a submittal requirement: 1) I do not need it immediately — but an updated cover sheet (current within 30 -days) for the Certificate of Conveyances is required. 2) The site map indicates a total of 8 natural gas compressors (is that correct?). Could you please state the total number of compressors (and type of compressor (gas vs. electrical) in the application narrative. This will make sure that it is clear to all referral agencies. 3) The County Code regulates all towers over 35 -feet. There are specific requirements that should be addressed for any communication tower on the site (regardless if it is oil and gas, telecommunication tower...) I don't know that Planning has been consistent in requiring a response to these items — but going forward I am going to require a response as it applies to towers (including towers applied for under a USR. Per Section 23-4-830 (which applies to towers over 35 -feet) — there are some criteria — you should address: A report describing the TELECOMMUNICATION FACILITY and the technical need and other reasons for its design, height and location; the need for the TELECOMMUNICATION FACILITY and its role in the network. The proposed TELECOMMUNICATION ANTENNA TOWER shall be the minimum height needed to accommodate the TELECOMMUNICATION ANTENNA. Existing or approved TELECOMMUNICATION ANTENNA TOWERS cannot accommodate the telecommunications equipment planned for the proposed TELECOMMUNICATION ANTENNA TOWER. A Decommissioning Plan. Adequate financial assurance to cover the decommissioning of the facility may be required as a condition of approval of the Decommissioning Plan. NOTE: I can proceed with setting up the case. But I would like this to be addressed during our review/referral process. 4) NOTE: I have been at two hearings where the question is being asked re: why compressors are electrical vs. natural gas (arguing that electrical is preferred due to noise and emissions reduction). I recommend that you be prepared to address why gas compressors vs. electrical compressors are proposed for this site. Let me know if you have any questions.
