Rose VP — Engineering 1 Construction Supplement Garfield County Building & Planning Department Minor (2 Lot) Exemption Application Application for Subdivision of: Assessor Parcel 24934200108 318 300 County Road Parachute, Colorado 81635 Exemption Lot: 10.5 acre parcel to be created out of 196 acre Parent Parcel Owners: Rodney C. Power, William R. Patterson, Ronald E. Tipping, Marie E. Tipping Supplement Re: How lack of water and sewer will be addressed in Plat and Deed The Parcel being subdivided is not suitable for a home or an office in that the surface of the parcel is taken up with compressors, meter stations and other commercial -type structures and there are several pipelines that cross under the parcel. The parcel is surrounded by other commercial activity and enterprises. The oil and gas commercial activity associated with the parcel is long term, if not permanent and the equipment installed on and under the Parcel is permanent in nature. The plat for the proposed subdivison can reflect that the subdivision parcel does not have water and sewer because of these permanent commercial uses and the parcel is not suitable for a home or an office. Any deed associated with the Parcel post -subdivision can have deed -restriction language such as, by way of example only: "Grantee acknowledges that the Lands being conveyed herein have a restricted use in that they do not have a sufficient legal and physical source of water or a sewer system and cannot accommodate a home or an office as noted in the that Subdivision dated filed in Garfield County, Colorado." Any future buyer of the property would see in a title check or county record check that the Parcel was so restricted.

This program was most recently amended on November 5, 2009 and the amended regulations took effect on January 14, 2010. These oil pollution prevention regulations require the preparation of a Spill Prevention Control and Countermeasure (SPCC) Plan for a facility engaged in drilling, producing, gathering, storing, processing, refining, transferring, distributing, using, or consuming oil and oil products, and which due to its location, could reasonably be expected to discharge oil in quantities that may be harmful, as described in 40 CFR Part 110, into or upon the navigable waters of the United States or adjoining shoreline, or into or upon the waters of the contiguous zone, or in connection with activities under the Outer Continental Shelf Lands Act or the Deepwater Port Act of 1974, or that may affect natural resources belonging to, or under the exclusive authority of the United States (40 CFR, Part 112.1(b)). The SPCC regulations and additional information can be found at: http./fwww.eoa.govloilspilllspcc.htm. The following sections of this plan are presented in the sequence of the SPCC rule, as required by the rule. The substantive requirements (§112.7 and §112.9) are addressed in Sections 7.0 and 9.0, respectively. Throughout this plan, where applicable, references to the appropriate subsections of 40 CFR Part 112 are provided, followed by an explanation of how the requirements have been addressed. 3 SECTION 4.0 GENERAL APPLICABILITY The Oil Pollution Prevention Regulations (40 CFR Part 112) require preparation of an SPCC plan for facilities that have discharged or could reasonably be expected to discharge oil into or upon navigable waters of the United States or adjoining shorelines, Specifically, §112.1(d)(2) requires an SPCC plan to be developed for facilities where the buried below ground storage capacity of oil is greater than 42,000 gallons or the aggregate aboveground storage capacity of oil is greater than 1,320 gallons (inclusive of containers with thresholds of 55 -gallons or greater). The Orchard Compressor Station covered in this SPCC plan has a collective potential maximum aboveground storage capacity above the threshold amount, thus GRG is required to develop, implement, and maintain an SPCC plan for the facility. The purpose of this SPCC plan is to identify sources of oil at the Orchard Compressor Station and outline procedures to prevent the release of oil into or upon navigable waters of the United States or that may affect the natural resources of the United States. Any facility that could, because of its location, be expected to cause substantial harm to the environment by discharging oil into or on navigable waters or adjoining shorelines is required to prepare and submit a facility response plan (FRP) to the USEPA Regional Administrator (RA) in accordance with 40 CFR Part 112.20. The Orchard Compressor Station is not considered such a facility because it does not meet any of the substantial harm criteria specified in §112.20. These criteria, and the associated applicability determination regarding the Orchard Compressor Station, are shown in Appendix A. This appendix is the Certification of the Applicability of the Substantial Harm Criteria required by §112.20 and must be maintained at the facility. Because submittal of an FRP is not required, except at the discretion of the RA, this SPCC plan provides information and procedures for responding to discharges. 4 SECTION 5.0 SPCC PLAN ADMINISTRATION: §112.3, §112.4, AND §112.5 5.1 Requirement to Prepare and Implement an SPCC Plan: §112.3 This SPCC plan is intended to comply with the SPCC rule (40 CFR Part 112) that was mast recently amended on November 5, 2009 and took effect on January 14, 2010. This facility was operational before November 10, 2011, so the provisions of §112.3(c) do not apply. This facility is not an onshore or offshore mobile facility, so the provisions of §112.3(c) do not apply. In accordance with §112.3(d), this SPCC plan has been reviewed and certified by a professional engineer. See Section 2.0 of this document. As this facility is not typically manned for at least 4 hours per day, in accordance with §112.3(e)(1) and (2), a complete updated copy of the SPCC Plan and associated files will be maintained at the GRG office in Rifle, Colorado. During normal working hours the plan will be available to authorized representatives of Local, State or Federal governing agencies for on-site review and a copy will be submitted to the EPA if requested. 5.2 Amendment of SPCC Plan by Regional Administrator: §112.4 In accordance with §112.4(a), whenever more than 1,000 -gallons of oil have been discharged in a single incident or more than 42 -gallons of oil have been discharged in each of two incidents over a 12 -month period, GRG will submit an incident report to the EPA RA within 60 days (refer to the definition of a discharge previously provided in Section 4.0). The report must include the following: • §112.4(a)(1): Name of the facility; • §112.4(a)(2): Name of the operator; • §112.4(a)(3): Location of the facility; • §112.4(a)(4): Maximum storage or handling capacity of the facility and the normal daily throughput; • §112.4(a)(5): Corrective action and countermeasures that have been taken, including a description of equipment repairs and replacements; • §112.4(a)(6): An adequate description of the facility, including maps, flow diagrams, and topographical maps, as necessary; • §112.4(a)(7): The cause of such discharge as described in 40 CFR 112.1(b), including a failure analysis of the system or subsystem in which the failure occurred; • §112.4(a)(6): Additional preventive measures taken or planned to minimize the possibility of recurrence; and • §112.4(a)(9): Such other information as the Regional Administrator may reasonably require pertinent to the SPCC Plan or discharge. 5 In accordance with 40 CFR 112.4(c), copies of the incident report will also be forwarded to the Colorado Oil and Gas Conservation Commission (COGCC) and/or the Colorado Department of Public Health and Environment (CDPHE) as appropriate (See Appendix B for spill reporting details). The RA may subsequently propose by certified mail or personal delivery that this SPCC plan be amended. GRG will act in accordance with §112.4(d), (e), and (f) and will amend this SPCC plan as needed within 30 days and implement the amended plan within six months, unless the RA specifies another date. 5.3 Amendment of SPCC Plan by Owners or Operators: §112.5 In accordance with §112.5(a), when there is a change in facility design, construction, operation, or maintenance that materially affects the facility's potential for a discharge, GRG will amend this SPCC plan within six months of the change and implement the amended plan as soon as possible, but not later than six months following preparation of the amendment. Modifications which may require plan amendments and certification include: - Commissioning or decommissioning of containers or oil -filled equipment - Replacement, reconstruction, or movement of containers or oil -filled equipment Reconstruction, replacement, or installation of piping systems Construction or other work that alters secondary containment structures Changes in stored materials or type of equipment service - Changes in operating and maintenance procedures that affect SPCC compliance. There are no exempted produced water containers at this facility, according to the requirements of §112.9(c)(6)(i), so sections §112.5(b) and (c) do not apply to this facility. In accordance with §112.5(d), GRG will also review this plan at least once every five years from the last review. As a result of the review, the plan will be amended within six months of the review if more effective prevention and control technology has been field -proven at the time of the review and will significantly reduce the likelihood of a discharge. The amended plan will be implemented as soon as possible, but not later than six months following preparation of the amendment, The designated person accountable for oil spill prevention at the facility (see Section 7.1) will document completion of each five year review, sign a statement as to whether the plan will be amended, and record the results in Appendix C. As required by §112.5(e), technical amendments to the plan will be certified by a Professional Engineer. Any such amendments to this SPCC plan shall be noted on the Amendment Log included in Appendix C of this SPCC plan. Entries into the log will indicate a general description of the changes that were made to the facility, the corresponding changes that were made to the SPCC plan, including plan section and page numbers, and the name and signature of the person making the changes. A new certification page will be signed, sealed and inserted into this plan to complete the amendment process. Non-technical changes include, but are not limited to, such items as: contact lists, more stringent requirements for stormwater discharges to comply with NPDES rules, phone numbers, product changes if the new product is compatible with conditions in the existing tank and secondary containment materials, and any other changes which do not materially affect the facility's potential to discharge oil. if GRG personnel are unsure whether the amendment is technical or non-technical, the amendments should be reviewed and certified by a Professional Engineer. 6 SECTION 6.0 QUALIFIED FACILITY PLAN REQUIREMENTS: §112.6 This facility either does not meet the qualified facility qualification criteria in §112.3(g), or the operator is not choosing to self -certify the SPCC plan. As such, the provisions of §1126 do not apply to this plan. 7 SECTION 7.0 SPCC PLAN GENERAL REQUIREMENTS: §112.7 This section presents facility -specific details associated with the general requirements for SPCC plans outlined in §112.7. As previously indicated in Sections 1.0, 2.0 and 3.0, this SPCC plan has been prepared in accordance with good engineering practice, with management approval at a level with authority to commit the necessary resources for full implementation, and in the sequence of the rule. 7.1 General Facility Information Name and type of facility: The Orchard Compressor Station is a natural gas production facility owned and operated by Grand River Gathering, LLC. The Orchard Compressor Station is considered a production facility, as it is upstream of associated custody transfer points to transportation -related systems. Location of facility: The Orchard Compressor Station is located in the southeast of the southwest quarter of Section 27 in Township 7 South, Range 96 West in Garfield County, Colorado. The town of Parachute, Colorado, which lies approximately 4.3 miles southwest of the facility, is the nearest population center_ See Figure 1 for additional site location information.

The facility is located in western Colorado, in Garfield County. The area surrounding the facility is considered multiple -use land and area activities include oil and gas exploration and production. The location of the facility and details of the oil storage areas are depicted in Appendix D. According to U.S. Geological Survey topographic mapping sources (Parachute, Colorado quadrangle), the site lies at an approximate elevation of 4,990 -feet above mean sea level with shallow relief in the immediate vicinity of the site. All existing drainages in the vicinity of the facility discharge to the Colorado River, which lies approximately 1,650 -feet east of the facility. Drainage within the site boundary is governed by surface topography. Downhill slope direction arrows on Figure 2 indicate the predicted general direction of storm water flow to the south. The facility consists of metering equipment, separation equipment, above ground storage tanks, and piping systems. Products related to the maintenance and operation of the facility are stored in above ground storage tanks. Natural gas liquids are occasionally taken from the facility via tank truck. The facility operates 24 hours per day and is inspected daily by operations personnel. An inventory of all facility storage tanks is provided in Section 7,5. Specific liquids stored at the facility are considered oils, as defined in 40 CFR §112.2, for the purpose of this SPCC plan. The facility is considered a production facility and is thus subject to the specific SPCC requirements of 40 CFR §112.9 for onshore production facilities. 7.3 SPCC Plan Conformance and Deviations: §112.7(a)(1) and (2) This SPCC plan is intended to conform to the applicable requirements of CFR 40 §112.7, as detailed in the subsequent sections of this SPCC plan. The Orchard Compressor Station is an onshore production facility and is therefore subject to §112.9. 7.4 Facility Layout: §112.7(a)(3) Oil storage areas at the facility are identified on Figure 2. There are no completely buried or bunkered tanks or connected underground piping at the facility as defined by §112.2 of the SPCC regulations, other than lines leading from the separation equipment to storage tanks. Aboveground storage containers and oil -filled equipment applicable to this plan are listed below in Section 7.5 7.5 Oil Storage Capacity: §112.7(a)(3)(i) A summary of the substances, containers, and container capacities applicable to this plan is provided in the following table. Although oil -filled equipment are not considered bulk storage containers as defined by §112.2, the applicability criteria such as oil storage capacity and potential for a discharge still pertain and the prevention of discharges from such equipment is covered in §112.7(k) of the SPCC rule. Consequently, the type of oil and capacity of the oil - filled equipment at the Orchard Compressor Station are included in the summary. 9 SPCC -Regulated Storage Containers and Oil -Containing Equipment Container/Equipment Description p Container Reference ID Container Storage Capacity (BBL) Net Containment Capacity (BBL) Lubricating Oil AST 1 11.9 16 Lubricating Oil AST 3 11.9 16 Condensate/Prod.

(Source: NOAA Atlas 2) 7.6 Discharge Prevention Measures: §112.7(a)(3)(ii) The Orchard Compressor Station relies on a number of measures to aide in the prevention of a discharge. Descriptions of these measures are provided below. * Routine maintenance of any oil -containing equipment is performed by trained personnel at the location of the equipment utilizing soaker pads and the available secondary containment structures andlor drip pans as warranted. • Each storage tank or vessel has a system in place that has been designed and installed in accordance with good engineering practice to prevent discharges. These features may include: adequate containment volume to avoid overfill during normal operations, and; high level sensors and controls to stop liquid flow. All discharge features are inspected at regular intervals. 7.7 Discharge or Drainage Controls: §112.7(a)(3)(iii) The products stored at the Orchard Compressor Station (e.g. natural gas liquids, produced water, and lubricating oil) are noncorrosive materials and are compatible with the materials with which the storage containers and containment structures at the facility are constructed. The containment structures at the facility are designed to provide adequate protection against the discharge of oil. Secondary containment is provided for the atmospheric aboveground storage tanks. Secondary containment details are provided in Section 7.14. Containment capacity calculations and/or specifications are provided in Appendix D. Each secondary containment system, including the walls and floor of each respective system, is 10 capable of containing oil and has been constructed so that any discharge from a primary containment system (such as a tank or pipe) will not permeate, drain, infiltrate, or otherwise escape before cleanup occurs. 7.8 Countermeasures for Discharge Discovery, Response and Cleanup: §112.7(a)(3)(iv) As part of routine facility operational procedures, visual exterior inspections of the oil storage containers and equipment are made several times per week, at a minimum, for signs of deterioration or leaks. Deficiencies noted from these examinations are entered on a check sheet and corrected in a timely manner. Inspection check sheets are kept in a logbook in the field office in Rifle, Colorado. In addition to the regular checks, the oil storage equipment is inspected annually according to the written procedures outlined in Section 7.15 of this plan. Any discharge occurring at the facility would likely be discovered by GRG operational personnel during routine site visits. Upon discovery, response procedures will be immediately initiated. In the event of a release, the facility has trained personnel and equipment available to contain and clean up minor volumes of discharged oil. On-site equipment and materials include spill kits, shovels, and sorbent materials (booms, pads, etc.) that may be used to dike, contain, and remove minor releases. In the event of a larger discharge, specific response procedures have been developed (See Appendix B). As part of these procedures, external resources (contractors) have been identified to assist facility personnel. To ensure the commitment of these external resources, GRG maintains a service agreement with each selected contractor. A list of approved contractors is kept at the facility and at the GRG office in Rifle, Colorado. At a minimum, contractors identified to assist in a spill response will have the capabilities to provide emergency response, industrial power vacuuming, tank and pipeline cleaning, equipment decontamination, excavation/earthmoving and waste transportation and disposal services. 7.9 Recovered Materials Disposal: §112.7(a)(3)(v) Materials recovered during a spill event will be appropriately containerized or will be remediated on site in accordance with Colorado Oil and Gas Conservation Commission (COGCC) stipulations. Soils and other solids will be placed in 55 -gallon drums or roll -off containers, or in other approved containers as warranted. Liquids will be placed in 55 -gallon drums or will be collected in a tank truck using industrial power vacuuming. Recovered materials will be labeled, characterized and disposed/recycled in accordance with applicable federal, state and local regulations. 11 7.10 Contact List and Notification Phone Numbers: §112.7(a)(3)(vi) The contact list for oil spill response activities is provided in Appendix B, as part of the Oil Spill Response Procedures developed for the Orchard Compressor Station, 7.11 Reporting and Notification Procedures: §112.7(a)(4) Reporting and notification requirements are outlined in the Oil Spill Response Procedures provided in Appendix B, 7.12 Oil Spill Response Procedures: §112.7(a)(5) Oil Spill Response Procedures for the Orchard Compressor Station are provided in Appendix B. 7.13 Discharge Analysis: §112.7(b) Pursuant to §112.7(b), the reasonably expected modes of equipment failure or accidental fluid release are: Failure modes: Corrosion, piping or valve failure, tank failure, pressure vessel rupture, overflow, overfilling, vandalism, lightning strikes, and human error. Rate of discharge flow: the rate of flow of an accidental release will vary depending on ambient conditions, the type of failure mode causing the release, the location of the release, and the volume of material stored in the container or equipment. The ambient temperature at the time of release can affect fluid viscosity and flow rates. Piping or valve failures can result in flow rates ranging from 1 to several hundred gallons per hour. Tank failures or lightning strikes can result in instantaneous releases of entire container volumes. - Discharge quantity: discharge quantities will vary depending on the type and location of the failure. Tank release quantities will not exceed the storage volume of the tank. Process equipment release quantities will be dependent on the length of time that the release goes undetected. - Preventative measures: Tanks and oil -filled equipment are constructed in accordance with API, ASME, or other applicable industry standards. Where practicable, diversionary or containment structures are in place to control or contain released fluids as described in this document. 7.14 Spill Containment: §112.7(c) Oil storage containers at the Orchard Compressor Station are equipped with secondary containment as noted in this document. Spill containment at the facility is described below: Secondary containment is typically provided for the lubricating oil, and condensate above ground storage tanks in the form of earthen dikes or steel -wall containers. Containment or discharge prevention measures for other oil -filled equipment and vessels is provided as described below in Section 7.22. 12 Containment structures are, or will be, configured to contain the storage capacity of the largest tank within the containment area, plus at least 2.2 inches of freeboard to accommodate precipitation associated with a 24-hour 25 -year storm event (Source: U.S. Department of Commerce National Oceanic and Atmospheric Administration Atlas 2, Volume iI). The containment volume calculations associated with the secondary containment structures are presented in Appendix D. 7.15 Spill Containment Practicability: §112.7(d) No discussions related to practicability are warranted because this SPCC plan either does not deviate from the requirements of §§112.7(c), 112.7(h)(1), 112.8(c)(2), 112.8(c)(11), 112.9(c)(2), 112.10(c), 112.12(c)(2), and 112.14(c), or, where it does deviate, the deviations are not practicability -caused issues. 7.16 Inspections, Tests and Records: §112.7(e) Oil storage containers, oil -filled equipment and related containment structures at the Orchard Compressor Station are visually examined several times per week, at a minimum, for signs of deterioration or leaks. These inspections are conducted as part of normal facility operations. Deficiencies noted from these examinations are entered on a check sheet and corrected in a timely manner. The equipment is also inspected annually according to the written procedure in Appendix E. Signed and dated records of all inspections and other pertinent information, such as spills, removal and disposal of spill contaminated materials, replacement or repair of equipment, and training are maintained for a minimum of 3 years. 7.17 Personnel Training and Discharge Prevention Measures: §112.7(f) Oil -handling personnel operating the facility are required to have training in the operation and maintenance of equipment to prevent the discharge of oil; discharge procedure protocols; applicable pollution control laws, rules, and regulations; general facility operations; and the contents of the facility SPCC plan. They are under the direct supervision of the Compression Supervisor, who is responsible for establishing performance and duty guidelines and is the designated person accountable for spill prevention at the facility. Regular safety meetings are held to discuss a variety of safety procedures and other pertinent job responsibility criteria. A written record of all training is maintained for three years. At a minimum, training is conducted annually and whenever new spill regulations are promulgated, existing operating systems are modified, personnel responsibilities change, or the SPCC plan is amended. In addition, regular safety meetings will be used as a forum to reinforce understanding of SPCC procedures as necessary. An outline of the topics to be covered during SPCC training is presented in Appendix F. Attendance rosters and other training records will be maintained at the field office in Rifle, Colorado for a period of no less than three years. 13 7.18 Security: §112.7(g) The security requirements of the SPCC rule are not applicable to the Orchard Compressor Station, as the facility is a production facility. 7.19 Facility Tank Car and Tank Truck Loading/Unloading: §112.7(h) The Orchard Compressor Station has no loading/unloading racks as defined in §112.2. Proper loading procedures will be followed and wheel chocks used by tank truck drivers to prevent vehicles from departing or moving before completed disconnection of flexible or fixed oil transfer lines. All tank truck drivers are required to comply with DOT regulations in 49 CFR Part 177 and facility standard operating procedures. All drivers must be authorized and/or certified by GRG. When possible, GRG operations personnel will remain with any delivery truck during filling operations to monitor the transfer; inspect outlets, connections and valves on the delivery tank truck before and after oil -filling operations; and make adjustments as necessary. The driver or an operations personnel member visually inspects all tank trucks before leaving the loading/unloading areas. The lowermost drain and all outlets of transport vehicles shall be inspected and, if necessary, make certain that they are tightened, adjusted, or replaced to prevent liquid discharge while in transit. 7.20 Brittle Fracture Analysis: §112.7(i) The Orchard Compressor Station has no field -constructed aboveground oil -storage containers that apply to this plan and therefore this section of the regulation is not applicable. 7.21 Applicable Requirements: §112.76) Sections 7.0 and 9.0 of this plan provide detailed discussions of conformance with the applicable requirements and other effective discharge prevention used at the facility. 7.22 Qualified Oil -filled Operational Equipment: §112.7(k) This facility contains qualified oil -filled operational equipment (i.e. equipment that includes an oil storage container in which the oil is present solely to support the function of the device and that has not had a single discharge exceeding 1,000 gallons or two discharges exceeding 42 gallons within a twelve month period in the three years preceding this plan). The qualified oil -filled equipment is included in the facility inspection program discussed in Section 7.16 of this plan to detect equipment failure and/or discharges. The equipment is covered by an oil spill contingency plan following the provisions of 40 CFR Part 109 as described in Appendix B. Section 1.0 of this plan contains a written commitment of manpower, equipment, and materials required to expeditiously control and remove any quantity of oil discharged that may be harmful. 14 SECTION 8.0 SPCC PLAN REQUIREMENTS FOR ONSHORE FACILITIES (EXCLUDING PRODUCTION FACILITIES): §112.8 The Orchard Compressor Station is not an onshore non -production facility. Consequently, the provisions in §112.8 do not apply. 15 SECTION 9.0 SPCC PLAN REQUIREMENTS FOR ONSHORE OIL PRODUCTION FACILITIES: §112.9 9.1 Oil Production Facility Drainage: §112.9(b) Precipitation that may accumulate in any contained area is normally allowed to evaporate. No automatic pumps or ejector devices are present in any of the containment areas. If removal of any water accumulated in the containment areas is necessary, it will be conducted under the direct supervision of responsible personnel as described in this section. Accumulated precipitation is removed, when necessary, from secondary containment areas using a vacuum truck, pump, or other appropriate method. Removed water is disposed of in accordance with applicable local, state, and federal regulations. Prior to removal of the water from any containment area, the responsible personnel visually inspect the water in the containment structure and note the appearance of the water in the facility logs. The name of the person draining the containment, as well as the date, time, and approximate quantity of water removed will also be recorded in the facility logs and kept on file with the SPCC documents for a period of at least three years. A secondary containment drainage log is included in Appendix E. The drain systems at the Orchard Compressor Station are of the `enclosed' type. All process effluents are routed through drain lines to storage tanks. No process effluents, untreated or treated, are released off-site. All field drainage systems (such as drainage ditches or road ditches) in the vicinity of the facility are inspected at regular intervals for the presence of accumulated oil that may have resulted from a small discharge. Any accumulated oil will be removed from these areas promptly upon discovery. 9.2 Oil Production Facility Bulk Storage Containers: §112.9(c) In accordance with §112.9(c)(1), the products stored at the Orchard Compressor Station are compatible with the materials with which the storage containers and containment structures at the facility are constructed. Specific secondary containment details are presented in Section 7.14. In accordance with §112.9(c)(2), the tank battery and oil -filled equipment areas are equipped with sized secondary containment or covered by discharge prevention measures as noted in this document. Secondary containment at the facility is described in Section 7.14 and Appendix D. In accordance with §112.9(c)(3), oil storage containers, oil -filled equipment and related containment structures at the Orchard Compressor Station are visually examined several times per week, at a minimum, for signs of deterioration or leaks. These inspections are conducted as part of normal facility operations. Deficiencies noted from these examinations are entered on a check sheet and corrected in a timely manner. The equipment is also inspected annually according to the written procedure in Appendix E. In accordance with §112.9(c)(4), each storage tank or vessel at the Orchard Compressor Station has a system in place that has been designed and installed in accordance with good 16 engineering practice to prevent discharges. These features may include adequate container volume to avoid overfill and high-level sensors and controls to stop liquid flow. All discharge prevention features are inspected at regular intervals. Certain flow-through process vessels at the facility are not equipped with sized secondary containment. The alternate requirements of §112.9(c)(5) are followed, including these actions: - Periodically and on a regular schedule, the process vessels and associated equipment are visually inspected and/or tested for leaks, corrosion, or other conditions that could lead to a discharge. Corrective action is taken, or repairs are made to process vessels and associated equipment when necessary as indicated by regularly scheduled visual inspections, tests, or evidence of an oil discharge. Prompt removal or initiation of actions to stabilize and remediate any accumulations of oil discharges associated with process vessels and associated equipment. If the facility discharges more than 1,000 gallons of oil in a single discharge, or discharges more than 42 gallons in each of two discharges, within any twelve month period, from process flow-through vessels, then GRG will make certain that all process vessels comply with the requirements of §112.9 within six months of the discharge. There are no produced water tanks at this facility subject to §112.9(c)(6). 9,3 Facility Transfer Operations, Oil Production Facility: §112.9(d) In accordance with §112.9(d)(1), all above ground valves and piping associated with transfer operations are periodically and regularly inspected for the general condition of flange joints, valve glands and bodies, drip pans, pipe supports, and other appurtenances. There is no saltwater/oil field brine disposal equipment at this facility subject to §112.9(d)(2). In accordance with §112.9(d)(3), the facility flowlines with the potential for a discharge are either provided secondary containment, or covered by an oil spill contingency plan following the provisions of 40 CFR Part 109 as described in Appendix B. Section 1.0 of this plan contains a written commitment of manpower, equipment, and materials required to expeditiously control and remove any quantity of oil discharged that may be harmful. In accordance with §112.9(d)(4), the facility adheres to a program of flowiine maintenance that includes: - Ensuring that flowlines and associated valves and equipment are compatible with the type of production fluids, their potential corrosivity, volume, and pressure, and any other conditions expected in the operational environment. Visually inspecting and/or testing flowlines and associated appurtenances on a periodic and regular schedule for leaks, oil discharges, corrosion, or other conditions that could lead to a discharge as described in §112.1(b). - Taking corrective action or making repairs to and flowlines and associated appurtenances as indicated by regularly scheduled visual inspections, tests, or evidence of a discharge.

Appendix B OH Spill Response Procedures Oil Spill Response Procedures FACILITY NAME: ORCHARD COMPRESSOR STATION FACILITY ADDRESS: SE SW SECTION 27 IN TOWNSHIP 7 SOUTH, RANGE 96 WEST IN GARFIELD COUNTY, COLORADO NEAR PARACHUTE, COLORADO REFERENCE: SECTION 7.12 OF SPCC PLAN WRITTEN PROCEDURES APPROVED BY: Signature Title Name (please type or print) Date Oil Spill Response Procedures 1. Response Management Structure The Spill Coordinator and Alternate Spill Coordinator(s) are responsible for implementing response procedures in the event of an oil spill or discharge emergency. These personnel have the authority to commit the resources necessary to carry out a response. However, all operating personnel at the Orchard Compressor Station receive training to familiarize themselves with all aspects of the SPCC Plan, facility operations, the location and characteristics of materials handled at the facility, and the location of all records within the facility; and are responsible for proper implementation of response procedures should the Spill Coordinator or Alternate Spill Coordinator(s) be unavailable. 2. Initial Response Releases at the Orchard Compressor Station will be discovered through observations made during the course of normal work activities, inspections of work areas and equipment, monitoring devices, or by chance. Discovering a release is the first step in initiating a response. Upon discovery, the individual discovering a release should immediately: 1. Assess the basic situation. 2. Stop the source of the release if safely possible using available resources (including spill kits). 3. Restrict ignition sources if the material is flammable. 4. Secure the area as off limits. 5. In the event that the incident poses an immediate threat of fire, explosion, or other impact to safety, health, or the environment, contact the local fire department at 911. DO NOT HANG UP after completing the report, let the dispatcher hang up first. 6. Report the release to the Spill Coordinator or an Alternate Spill Coordinator (see attached Oil Spill Incident Notification Phone Numbers). 7. The Spill Coordinator (or alternate) will determine whether the spill incident warrants evacuation of the facility. If so, the procedures outlined in the facility Emergency Action Plan will be followed. 8. The Spill Coordinator (or alternate) will determine whether the spill incident constitutes a discharge as defined in §112.1(b) of the SPCC regulations (see Section 3, below) and will notify appropriate federal, state, and local agencies of the spillfrelease incident if warranted. 9. If the spill involves a minor volume of oil, it can be cleaned up by facility personnel provided that 1) they are OSHA trained and have received their current refresher training; 2) appropriate material safety data sheets (MSDS sheets) are available for the material spilled; and 3) appropriate personal protective equipment (PPE) is available. 10. If the spill involves a significant volume of oil, or any of the three criteria listed in (9) above are not met, it should be cleaned up by a properly certified outside contractor (see attached Oil Spill Incident Notification Phone Numbers). 3. Oil Spill Emergency Reporting if the release constitutes a discharge as defined in §112.1(b) of the SPCC regulations, it will be considered an Oil Spill Emergency. A release of oil is considered a discharge under this Plan only if: the release is into or upon the navigable waters of the United States, adjoining shorelines, or waters contiguous with navigable waters of the United States. This is apparent if a release impacts surface water quality by causing a film, sheen, or discoloration of the water surface, or upon water or adjoining shorelines, or causes a sludge or emulsion to be deposited beneath the surface of the adjoining shorelines. Impacts to groundwater also apply if the groundwater is contiguous with navigable waters of the United States (i.e., groundwater discharges to/contributes to the total volume of a surface water body that is itself contiguous with navigable waters of the United States). In summary, if a release directly affects surface water or groundwater at the facility, it must be considered an Oil Spill Emergency. Federal and local authorities to be notified in the event of an Oil Spill Emergency are outlined below. State of Colorado In Colorado, a spill or release of E&P wastes or produced fluids is to be reported within 24 hours if the spill has entered waters of the state (any surface or groundwater) or entered navigable waters (any surface water) in sufficient quantities to cause a sheen on the water or stain on the shore. Spills less than 5 barrels that do not impact, or threaten to impact, water, and which can be immediately contained and cleaned up, do not need to be reported. Spills greater than 20 barrels must be reported with 24 hours. All spills and releases of exploration and production waste or produced fluid exceeding five barrels, including those contained within lined or unlined berms, shall be reported in writing on the Colorado Oil and Gas Conservation Commission (COGCC) Spill/Release Report Form 19 within 10 days of discovery of the spill. In addition, spills or releases that exceed twenty barrels of exploration and production waste or produced fluid shall be reported on COGCC Form 19 and verbally reported to the COGCC as soon as practicable within 24 hours of discovery. Spills or releases of any size that impact or threaten to impact any waters of the state, residence or occupied structure, livestock or public byway, shall be verbally reported to the COGCC Environmental Release/Incident Report Hotline (1-877-518-5608) as soon as practicable after discovery. See COGCC Rule 906 for more information. If the spill may reach waters of the State (which include surface water, ground water and dry gullies or storm sewers leading to surface water), it must also be reported immediately to the Colorado Department of Public Health and Environment. Refined petroleum releases must be reported if they have entered navigable waters or if the quantity release exceeds 25 gallons. In general, verbal or telephone reports are to be made within 24 hours. The Director, Engineering, Construction and Operations or the Compression Supervisor will notify regulatory agencies as appropriate. As a practical matter, an evaluation of the specifics of each spill and a determination of reporting requirements will be made. If there is any question about reporting requirements, GRG will over -report rather than under -report. Written, follow up reports are to be sent within 10 days to: - Colorado Oil and Gas Conservation Commission 1120 Lincoln # 801 Denver, Colorado 80203 (Use COGCC Spill/Release Form) - Bureau of Land Management - File an "Undesirable Event Form" with:.

Responsibilities These procedures establish the requirements for periodic inspections and tests for the oil storage vessels and oil -filled equipment listed at the Orchard Compressor Station, to minimize the risk of a spill incident. The Compression Supervisor is responsible for the implementation of these procedures. Specifically, the Compression Supervisor is responsible for: ■ Conducting the inspections; • Producing documentation for deficiencies found during the inspections: and • Making certain that remediation or repair work is properly prioritized and completed in a timely manner. The Compression Supervisor may designate another personnel member to complete the inspections. Designated personnel will have the authority to commit the resources necessary to carry out a response, if warranted. Operating personnel at the Orchard Compressor Station receive training to familiarize themselves with all aspects of the SPCC Plan, facility operations, the location and characteristics of materials handled at the facility, and the location of pertinent records within the facility. 2. Procedures The Compression Supervisor (or designee) will conduct an annual visual inspection of the oil storage vessels and oil -filled equipment identified in Section 7.5 of the SPCC Plan. The inspections will be documented using the attached inspection forms. The annual inspection includes a visual examination of exterior surfaces for leaks and other deficiencies of the vessel, supports, connected piping and valves and secondary containment. It also includes visual inspection and monitoring of any leak detection system or other monitoring or warning systems (e.g., level indication/alarm or interstitial space monitoring). If any inspection reveals a leak or equipment deficiency outside of normal operating conditions, corrective action must be taken promptly to eliminate the leak or deficiency. Deficiencies noted during the inspection are recorded as a work order. The inspector will complete the following: 1. Visually inspect exterior surfaces of storage vessels and oil -filled equipment, along with associated piping, valves and other appurtenances for: o Drip marks or droplets of fluid/stored materials • Discoloration on equipment or ground surfaces • Puddles of spilled or leaked material o Corrosion o Cracks o Localized dead vegetation. 2. Visually inspect vessel/equipment supports, foundations, and containment structures for excessive settlement, apparent structural weakness, cracks or other deficiencies that would allow tanks or secondary containment structures to fail or leak. 3. Inspect and monitor existing leak detection systems (for example, observation ports on double -bottom tanks), cathodic protection equipment and other warning systems such as alarms and level gauges. If, during the annual inspection, the inspector observes a spill of oil from any of the equipment the inspector shall immediately initiate the oil spill response procedures outlined in Appendix B of this SPCC Plan. r Approximate Method of Removal and Quantity Removed (Gals) Disposal Appearance (visual, odor, etc.) Note: Do not discharge water containing any contaminant andior free oil or an oil sheen.

Disturbance Length: — 1,293 ft. (Includes both Red Boundaries depicted in Weed Site Map) Approximate Acreage 10.747 acres of disturbance: Site Maps: Attachment 1A: Weed Site Map & Attachment 1 B: Lot 1 Exemption Map Land Ownership: Tipping Site Inspection and Survey Date of Inspection: 11/13/12 Name of Inspector: Romana Sutton, Environmental Consultant Soil Type(s): 100% Arvada loam, 1 to 6 percent slopes (See Attachment 2: Orchard Compressor Station Soil Report) Description of Existing Vegetation (Appendix 1): Sagebrush Shrublands - See Appendix 1 for a description of species that would exist in the absence of development. Due to high traffic, industrial nature of this site, little to no vegetation exists Existing Vegetation Comprehensive Plant List Scientific Name Common Name NA NA Existing Weed Species (See Appendix 2 for State Priority Listing, Attachment 3 for Site Photos): Common Name Scientific Name State Weed List Downy Brome Kochia Bromus tectorum C NA. Kochia scoparia Primary Land Use: Previously disturbed industrial area; current location of Orchard Compressor Station. Bareground management has been maintained to prevent safety hazards, so little vegetation exists. Shows no sign of livestock or wildlife use. Additional Land Impacts: This site is adjacent to very high use traffic zones (roads, residential sites, industrial sites). Small portions of disturbance that lie outside of bareground boundaries which have been seeded continue to receive a high amount of traffic. Topsoil Handling All efforts shall be made during active construction of proposed facilities to preserve the physical structure, mineral composition and biotic properties of the native topsoil. Top soil shall be reserved and stockpiled separately from subsoils. On access road and well pads, all accessible topsoil shall be removed from areas that are to be excavated, covered in subsoils, or turned into stabilized unpaved surfaces. On well pads, if the initial topsoil stockpile areas are insufficient to accommodate the quantities of topsoil being generated, the excess shall be placed at either end of the subsoil stockpile and segregated as much as possible. On buried pipeline rights-of-way, all accessible topsoil (from the entire width of the right-of-way) shall be removed and temporarily stockpiled along the up -hill side of the right-of-way (if terrain grades will allow) for later use in reclamation activities. After major earthwork, grading, and erosion/drainage/sediment controls are complete, any areas that can be identified for immediate interim reclamation shall receive topsoil. On access roads, the topsoil is to be windrowed on the access road side of the vegetation windrow. After final grade has been established and/or pipeline installation is complete and final grade has been established the topsoil shall be dispersed on the fill slope of the access road for immediate interim reclamation. Revegetation It is proposed that disturbed areas will be reseeded using a seed mix similar to that provided in Attachment 3: Seed Tags. This mix has been utilized in adjacent areas. Seed will preferably be applied by drill -seeding at an application rate of approximately 24.8 lbs per acre. If applied by broadcast, this rate should be doubled. Stormwater, Run-off, Errosion Control Stormwater management and run-off control BMPs shall be implemented on this proposed site, as determined by the Colorado Department of Public Health and Environment. Common Name Scientific Name Treatment Method Downy brome Kochia (See Attachment 3) Bromus tectorum Cultural Chemical Chemical/ Mechanical Kochia scoparia Noxious Weed Management Pre -disturbance site preparation. Weed removal and/or control efforts will be implemented prior to site disturbance, as conditions allow. For this specific site, the following weed management efforts will be implemented for the weeds currently known to occupy the site: Timing of Ap • lication At time of Reclamation Pre -emergent bareground treatments in early spring Post -emergent spot treatment throughout growin• season Chemical controls will be applied in accordance to the consultation of a commercial pesticide applicator, licensed by the state of Colorado Department of Agriculture. Following completion of the proposed facility, this site will be monitored and treated as deemed appropriate, in accordance with the control level requirements determined in the Colorado Noxious Weed Act. Site Monitoring The proposed site will be visually monitored for surface erosion, run-off and stormwater management, as well as revegetation success and noxious weed encroachment. Visual monitoring will occur no less than every 30 days until 70% of the pre-existing vegetation cover is restored.

Common species among the sparse understory consist of common juniper, kinnikinnik, sticky -laurel, Junegrass, stonecrop, Colorado locoweed, and whitlow -wort (Draba spp.). Lichens cover exposed rock surfaces. 7. Alpine Tundra. Tundra vegetation consists of a low growth of shrubs, cushion plants, and small forbs with brilliantly colored flowers, and of lush meadows of narrow -leaved sedges and grasses. These plants cover gentle slopes and rock crevices filled with soil. Rock surfaces are partially covered with more primitive plants --- lichens and mosses. Shrubs consist of arctic willow (Salix arctica), barrenground (Salix brachycarpa), planeleaf (Salix planifolia), and snow (Salix reticulate ssp. nivalis).

All plant species are slow-growing perennials except for the rare annual koenigia, a tiny member of the buckwheat family. 8. Urban Areas. Urban areas contain an increased density of human -created structures in comparison to the areas surrounding it. Depending on the area, vegetation may account for anywhere between 20 and 70 percent of the total land cover, with the remaining portion being constructed materials. Types of vegetation within urban areas may be any combination of the above ecosystems, and may include areas of blue grass yards and parks. 9. Cropland. Cropland vegetation may consist of wheat, corn, soybeans, or a variety of many other crops. Cropland may either lie fallow (bare of any crops) or contain crops at any stage of growth from seedlings to mature plants.

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 an 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:llsoils.usda.govlsgil) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (http:lloffices.sc. egov.usda.govllocator/app? agency=nrcs) or your NRCS State Soil Scientist (http:llsoils.usda.govlcontactl state_offices/). 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 Soil Data Mart Web site or the NRCS Web Soil Survey. The Soil Data Mart is the data storage site for the 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 there 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 scientists classified and named the soils in the survey area, they compared the 5 Custom Soil Resource Report 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 Iandforms 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 Iandforms 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 level's 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 an 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 identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. 6 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 an 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 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. 10 100.0% 100.O% Custom Soil Resource Report 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 rnanagement. 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. 11 Custom Soil Resource Report Rifle Area, Colorado, Parts of Garfield and Mesa Counties 3—Arvada loam, 1 to 6 percent slopes Map Unit Setting Elevation: 5,100 to 6,200 feet Map Unit Composition Arvada and similar soils: 80 percent Minor components: 5 percent Description of Arvada Setting Landform: Terraces, fans Landform position (three-dimensional).: Tread Down-slope shape: Convex, linear Across -slope shape: Convex, linear Parent material: Highly saline alluvium derived from sandstone and shale Properties and qualities Slope: 1 to 6 percent Depth to restrictive feature: More than 80 inches Drainage class: Well drained Capacity of the most limiting layer to transmit water (Ksat): Moderately low to moderately high (0.06 to 0.20 in/hr) Depth to water table: More than 80 inches Frequency of flooding: None Frequency of ponding: None Calcium carbonate, maximum content: 10 percent Gypsum, maximum content: 2 percent Maximum salinity: Very slightly saline to moderately saline (4.0 to 16.0 mmhos/cm) Sodium adsorption ratio, maximum: 30.0 Available water capacity: Moderate (about 8.0 inches) Interpretive groups Farmland classification: Not prime farmland Land capability classification (irrigated): Ts Land capability (nonirrigated): 7s Hydrologic Soil Group: D Ecological site: Salt Flats (R048AY261C0) Typical profile 0 to 3 inches: Loam 3 to 17 inches: Silty clay loam 17 to 60 inches: Silty clay loam Minor Components Wann Percent of map unit: 5 percent Landform: Terraces Landform position (three-dimensional): Tread 12 Custom Soil Resource Report 13 References American Association of State Highway and Transportation Officials (AASHTO). 2004.
