REPRESENTATIVE: Lorne Prescott, Olsson Associates Mike Bonkiewicz, Noble Energy Inc. PRACTICAL LOCATION: Approximately 9 miles south west of Parachute, off of County Road 305 and generally situated in Section 1, TBS , R96W. ZONING: Rural (R) TYPE OF APPLICATION: Limited Impact Review Land Use Change Permit for a Storage Facility I. GENERAL PROJECT DESCRIPTION The Applicant proposes the creation of a storage facility on an existing disturbed site. The project area is approximately 2.11 acres in size and was originally developed in conjunction with the Noble Energy SGV 1 K Well Pad . The proposal includes the storage of typical oil and gas support equipment and materials . Pipe lay down and storage, temporary storage of empty tanks prior to installation, storage of valves, and storage of construction materials all are possible uses for the storage area . The Storage Facility will support oil and gas operations and construction activities in the immediate vicinity of the facility. The site is represented to be graded and leveled at this time . A small section of new or upgraded access road is planned to better serve the facility. The road extends through the adjoining Noble well pad which is located just south of the proposed storage area. No security fencing (chain link) is proposed however agricultural fencing may be in place or installed . No water or sanitary facilities are anticipated to be needed to serve the use as the proposal is to operate as an unmanned facility. Pre-application discussions did cover the potential for water supply to be addressed by provision of individual bottled water in employee trucks and the current location of portable toilets at nearby Noble facilities to address sanitation needs. No new site disturbance is planned other than the small section of roadway. The facility is anticipated to help reduce heavy truck traffic on County roads allowing easier more efficient access to equipment. The Application will need to clarify if there will be any storage of hazardous materials. It is Staff's understanding that no tanks or storage of liquids are proposed II.

RAMOS LAYDOWN YARD WAIVER REQUESTS Pursuant to Section 4-202 of the Garfield County Land Use and Development Code, Noble Energy, Inc. (Noble) requests a waiver for the submittal requirement of a Development Agreement and Improvements Agreement for the Ramos Laydown Yard. Section 4-203.J. Development Agreement A waiver request shall be considered based on the following criteria: 1. The Applicant shows good cause for the requested waiver; Response: Noble wishes to neither propose a phasing schedule or extend establishment of vested property rights. 2. The project size, complexity, anticipated impacts, or other factors support a waiver; Response: The facility is largely constructed and does not require additional improvements to operate as a storage facility. 3. The waiver does not compromise a proper and complete review; and Response: The request can be properly and completely reviewed without a development agreement. 4. The information is not material to describing the proposal or demonstrating compliance with approval criteria. Response: A development agreement is not material to describing the purpose, operation and maintenance of the facility or demonstrating compliance with applicable approval criteria. Section 4-203.K. Improvements Agreement A waiver request shall be considered based on the following criteria: 1. The Applicant shows good cause for the requested waiver; Response: No public improvements are being proposed that would warrant the creation of an improvements agreement. 2. The project size, complexity, anticipated impacts, or other factors support a waiver; Response: As stated above no public improvements are being proposed with this request. 3. The waiver does not compromise a proper and complete review; and Noble Energy Inc. Ramos Laydown Yard Waiver Requests Page 2 Response: The application can be properly and completely reviewed without an improvements agreement. 4. The information is not material to describing the proposal or demonstrating compliance with approval criteria. Response: An improvements agreement is not material to describing the purpose, operation and maintenance of the facility or demonstrating compliance with applicable approval criteria. Pursuant to Section 4-118 of the Garfield County Land Use and Development Code, Noble requests waivers for the following standards for storage setback for the Ramos Laydown Yard. Section 7-107 Access and Roadways F. Design Standards. Roadways, surfaces, curbs and gutters, and sidewalks shall be provided as follows (see Table 7-107: Roadway Standards): A waiver of standards request shall be considered based on the following criteria: 1. Achieves the intent of the subject standard to the same and better degree than the subject standard: Response: The intent of the ditch width and cross slope is to facilitate proper drainage off the roadway. The area where the roadway does not meet the cross slope standard is short and in the middle of the well pad that the road goes through. The cross slope in this section is 2.5% on half of the roadway and 0.6% on the other half. The surface is graveled and the drainage is not compromised by this steeper cross slope. There are not ditches along this roadway. Because it crosses an existing well pad location. The road is regularly maintained and run-on/run-off is addressed via implementation of Noble’s Stormwater Management Plan. 2. Imposes no greater impacts on adjacent properties than would occur through compliance with the specific requirements of this Code. Response: Full compliance with the cross slope standard would require that the road be regraded, causing additional disturbance on site to fix a very short section of the roadway. Adding ditches to the roadway through the existing well pad would put traffic barriers to activities on the well pad. These deficiencies do not impose any impacts on adjacent properties than would occur through compliance with the standards. Noble Energy Inc. Ramos Laydown Yard Waiver Requests Page 3 Section 7-1001 Industrial Use D. Storing 3. Shall be a minimum of 100 feet from an adjacent property line. A waiver of standards request shall be considered based on the following criteria: 3. Achieves the intent of the subject standard to the same and better degree than the subject standard: Response: The intent of the setback standard is to provide separation between dissimilar uses. The proposed storage area would be approximately 30 feet from an adjacent property line located directly west of the laydown yard. This adjacent property located to the west is approximately 59 acres in area and contains agricultural buildings, irrigated hay fields and oil and gas production facilities. Immediately west of the laydown yard area is an access road to an oil and gas production facility. Immediately west of this access road is a well pad with production equipment. A residence is located approximately 1500 feet west of the storage area on another parcel. The proposed setback does not significantly reduce the separation between the residential use located to the west and the laydown yard. The established oil and gas production facilities in the area are located closer to this residence than the proposed laydown yard. 4. Imposes no greater impacts on adjacent properties than would occur through compliance with the specific requirements of this Code. Response: Full compliance with the code would increase the distance between the laydown yard and the residence to the west by less than an additional 5 percent. The proposed setback would not impose an additional impact on the residential use than it would under the full standard. Noble Energy Inc.

RAMOS STORAGE AREA LIMITED IMPACT REVIEW APPLICATION As detailed in this application, NOBLE ENERGY, INC. (Noble) is requesting a Limited Impact Review (LIR) to allow a laydown yard (Storage Use). The property is zoned Rural by Garfield County. Table 3-403 of the Garfield County Land Use and Development Code identifies storage use as requiring a Limited Impact Review in this zone. The facility will be at an elevation of approximately 5,845 feet. The proposed project area is in a location that provides convenient field access for Noble operations. In addition, this land use will take advantage of a previously permitted surface disturbance and stay within the boundaries of the existing disturbance. The project site is located is approximately 5.25 miles southeast of the town of Parachute, Colorado in Sec. 1, T8S, R94W, 6th PM in Garfield County. The total project area is approximately 2.10 acres. The proposed laydown yard will utilize an existing disturbance. The use is intended accommodate storage of equipment and supplies on-site for convenient access (as needed) related to Noble’s natural gas drilling and production activities. The proposed use is compatible with surrounding properties which are similar and are host to natural gas operations. This property is located within the Rural (R) zone district and is not within a platted subdivision . Storage Areas are an allowed use in the subject zone district provided the LIR is approved. The proposed facility meets all applicable standards for the Rural zoning district. The adjacent properties are primarily undergoing oil and gas development and have limited residential and agriculture operations. Due to the location of the facility, the proposed use will have minimal impact, if any, to the surrounding area. Project activities will generate little or no noise impacts thus sound impacts will be easily accommodated by the Garfield County and Colorado Revised Statue noise standards. The Ramos Storage Area application is requesting a waiver of the 100 foot setback standard found in Section 7-1001.D.3 of the Land Use and Development Code. The proposed setback of approximately 30 feet meets the intent of the code of providing separation between dissimilar uses and does not impact the residential use more than if it was in full compliance with the code. A complete analysis of this request is located in the Waiver Requests section of the application. An area-wide Stormwater Management Plan (SWMP) detailing the use of site-specific Best Management Practices (BMPs) associated with Noble’s construction activities will be utilized for the proposed project. Implementation of the SWMP will ensure that activities conducted at the site comply with stormwater management regulations as required by Garfield County, the State RAMOS Storage Area Noble Energy, Inc. Project Description Page 2 of Colorado, and the United States Environmental Protection Agency. Through this plan, disturbed soils will be reseeded to regain stability as soon as practical and BMPs will be utilized to mitigate sediment erosion and transportation. Implementation of these plans also ensures that installation and operation of this facility will not impact surface runoff, stream flow, or groundwater. This facility will be in operation for approximately thirty (30) years, the expected lifespan of the associated gas wells in the area. When the facility is no longer needed to support operation of the wells in the area, this site will be reclaimed by removing all surface equipment and structures, grading to restore original contours, replacing any topsoil that may have been removed, and revegetating the reclaimed area with the applicable seed mix. See Reclamation Plan for further information. Hazardous materials will not be stored at this location. The proposed use will require minor additional surface disturbance. Noble employees and contractors will be on-site for short intervals picking up or dropping off supplies. Sanitation facilities, potable water and office space are not proposed. Portable toilets are provided throughout the area for use by field employees. The site will be fenced. Access to the Storage Area is via Garfield County Road (CR) 300 (Stone Quarry Road) to CR306 (Wallace Creek Road) for approximately 2.4 miles then on to a private access road (see Access Road Map). The Ramos Storage Facility location is approximately 0.5 miles north of CR306 on this private access road. There is no historic public access through the proposed site. See Traffic Analysis for further information. No significant natural or geological hazards are found at the project site. Because this is a previously disturbed location with minor additional disturbance anticipated, impacts on wildlife and native vegetation will be negligible. No smoke, vibration, heat, radiation or fumes will be produced as a result of the operation of this facility. Adjacent properties will not be affected by the operations. A public nuisance or hazard will not be created. Traffic impacts to public roads will be minimal and will not require additional improvements or permits. Potential impacts to wildlife, natural environment, and the surrounding properties are expected to be minimal, if any. The proposed facility will be located on an existing disturbed area. The remote location of this facility and the type of operations which will occur should eliminate the majority of the impacts required to be addressed in this application. The topography surrounding the facility acts as a visual and sound barrier in most directions. The facility will be partially visible from surrounding properties and public roads.

Ramos Garfield County, CO 013-2329 1 I. INTRODUCTION A. Background This Final Drainage Report has been prepared by Olsson Associates for Noble Energy Inc.’s proposed laydown storage area, located next to the pad SGV 1K. The laydown Yard will be known as the Ramos site (the site). This report evaluates the site’s existing drainage patterns, analyzes the change in stormwater quantity/quality associated with proposed development, and provides design to alleviate the impacts of increased stormwater runoff due to the proposed development. B. Project Location The site is located in the NE ¼ of the SW ¼ of Section 1, Township 8 South, Range 96 West of the Sixth Principal Meridian, County of Garfield, State of Colorado. The site is approximately 8.3 miles northeast of the town of De Beque. Refer to Figure 1 for project location. Figure 1: Vicinity Map C. Previous Investigations To the best of our knowledge, no previous drainage investigations have been conducted in regards to this site. SITE DRAINAGE REPORT Noble Energy Inc. Ramos Garfield County, CO 013-2329 2 D. Property Description The site consists of an existing 2.25 acre pad site that was previously graded into mountainous terrain. The site owner plans to upgrade the site into a laydown storage area. The topography is generally flat and drainage from the site travels to the northwest corner. According to the NRCS Web Soil Survey, soil in the area of the site consists of Potts loam, which is classified as hydrologic soil group Type C. A soil map from NRCS is included in Appendix A. II. DRAINAGE SYSTEM DESCRIPTION A. Existing and Proposed Drainage Conditions The site consists of two pads connected by an access road. The pad is divided into three sub- basins, A, B, and C. Drainage basin A comprises 1.71 acres of the developed area, and drains via sheet flow to the northwest corner of the site, where a berm (design point 1) will provide detention for the 24 hour 25 year storm. Basin B comprises 0.53 acre of the developed area and generally sheet flows offsite to an existing and natural drainage way. The up slope area located on the east side of the site, denoted as drainage basin OS, drains toward the pad. The runoff from drainage basin OS will be intercepted by a proposed swale (design point 2), which runs along the eastern property boundary between basins OS and B. This swale will discharge to an existing swale in basin B, where the flow will comingle with the flow from basin B and ultimately be discharged to an existing and natural drainage way. . Table 1: SITE Peak Runoff (Existing and Proposed) Basin ID 25-YR Peak Flow (cfs) 100-YR Peak Flow (cfs) Description A 2.42 3.92 Flow to basin B 0.68 1.17 Flow off-site OS-1 2.64 4.80 Conveyed around site B. Master Drainage Plan To our knowledge, no master drainage studies have analyzed the site. C. Drainage Facility Maintenance The owner shall be responsible for maintaining all on-site drainage facilities. In addition, the detention basin and swales should be examined after any significant rainfall event to ensure proper functionality and prevent erosion. DRAINAGE REPORT Noble Energy Inc. Ramos Garfield County, CO 013-2329 3 III. DRAINAGE ANALYSIS AND DESIGN CRITERIA A. Regulations This report has been prepared in accordance with common engineering practices, the Urban Drainage and Flood Control District’s Urban Storm Drainage Criteria Manual, and Garfield County standards. B. Development Criteria There are no known constraints placed on the site due to floodplain studies, master drainage studies or adjacent property drainage studies. Flows from upstream land will be diverted around the site. C. Hydrologic Criteria Hydrologic calculations have been prepared in accordance with common engineering practices. Rainfall intensities used are sourced from the NOAA Atlas 14 Hydrometeorological Design Studies Center. Refer to Appendix C for all hydrologic calculations. D. Hydraulic Criteria Hydraulic calculations have been prepared in accordance with common engineering practices and the Urban Drainage, Flood Control District’s Urban Storm Drainage Criteria Manual, and Garfield County Land Use and Development Code, Article 7 Section 204. IV. POST-CONSTRUCTION STORMWATER MANAGEMENT A. Stormwater Quality Control Measures The detention basin (design point 1), which was designed to detain the 24 hour 25 year storm will provide the required stormwater quality control measures of detaining the 0.5 inch 24 hour storm. See Appendix B for the infiltration calculations. V. CONCLUSIONS A. Compliance with Manual This report has been prepared in accordance with common engineering practices and the Urban Drainage and Flood Control District’s Urban Storm Drainage Criteria Manual. DRAINAGE REPORT Noble Energy Inc. Ramos Garfield County, CO 013-2329 4 B. Compliance with Colorado Oil and Gas Conservation Commission Criteria 100-Year Run-on Diversions Along the east side of the site, a swale will be constructed to convey the run-on flow. The proposed swale will discharge to an existing swale on the north side of the site and ultimately discharge to an existing and natural drainage way. 25-Year Run-off Control Run-off from the site will be captured in the northwest corner of the site. Run-off control will be handled with a berm and an outlet weir. Design Effectiveness Proper implementation of the proposed measures outlined in this report will alleviate the direct impacts of stormwater run-off on adjacent, downstream lands. The quantity of stormwater released from the site will be equivalent to existing conditions. A registered licensed engineer in the state of Colorado should be consulted for the preparation of construction plans related to the recommendations outlined within this report. C. Areas in Flood Hazard Zone The site is within the FEMA Panel 0802051700B, which has not been printed. Based upon this and the relative elevation above the nearest major river (approximately 800 vertical feet), the flood risk has been determined to be minimal. VI.

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.

This permit also authorizes the discharge of specific allowable non-stonnwater discharges, in accordance with Part I.D.3 of the permi4 which includes discharges to the ground. This includes stonnwater discharges from areas that are dedicated to producing earthen materials, such as soils, sand and gravel, for use at a single construction site (i.e., borrow or ftll areas). This permit also authorizes stormwater discharges from dedicated asphalt batch plants and dedicated concrete batch plants. (Coverage under the construction site permit is not required for batch plants if they have alternate CDPS permit coverage.) This permit does not authorize the discharge of mine water or process water from such areas. a) .Applicable Sections: In accordance with Part I.A.3 of this permit, some parts of this permit do not apply to sites covered under a Qualifying Local Program, as defmed in I.A.2.d. For sites not covered by a Qualifying Local Program, all parts of the permit apply except Part l.A.3. The permittee will be responsible for determining and then complying with the applicable sections. b) Oil and Gas Construction: Stormwater discharges associated with construction activities directly related to oil and gas exploration, production, processing, and treatment operations or transmission facilities are regulated under the Colorado Discharge Permit System Regulations (5CCR 1002-61), and require coverage under this permit in accordance with that regulation. However, references in this permit to specific authority under the Federal Clean Water Act (CW A) do not apply to stormwater discharges associated with these oil and gas related construction activities, to the extent that the references are limited by the federal Energy Policy Act of 2005 . . 2. Definitions a) Stormwater: Stormwater is precipitation-induced surface runoff. b) Construction activity: Construction activity refers to ground surface disturbing activities, which include, but are not limited to, clearing, grading, excavation, demolition, installation of new or improved haul roads and access roads, staging areas, stockpiling of fill materials, and borrow areas. Construction does not include routine maintenance to maintain original line and grade, hydraulic capacity, or original purpose of the facility. c) Small construction activity: Stonnwater discharge associated with small construction activity means the discharge of stormwater from construction activities that result in land disturbance of equal to or greater than one acre and less than five acres. Small construction activity also includes the disturbance of less than one acre of total land area that is part of a larger common plan of development or sale, if the larger common plan will ultimately disturb equal to or greater than one and less than five acres. d) Qualifying Local Program: This permit includes conditions that incorporate qualifying local erosion and sediment control program (Qualifying Local Program) requirements by reference. A Qualifying Local Program is a municipal stormwater program for stormwater discharges associated with small construction activity that has been formally approved by the Division. Other Definitions: Defmitions of additional terms can be found in Part I.E. of this permit. 3. Permit Coverage Without Application-for small construction activities under a Qualifying Local Program only If a small construction site is within the jurisdiction of a Qualifying Local Program, the operator of the construction activity is authorized to discharge stormwater associated with small construction activity under this general permit without the submittal of an application to the Division. a) Applicable Sections: For sites covered by a Qualifying Local Program, only Parts l.A.1, l.A.2, l.A.3, I.D.l, l.D.2, I.D.3, I.D.4, I.D.7, I.D.8, I.D.11, LE and Part II of this permit, with the exception of Parts II.A.I, II.B.3, II.B.8, and II.BIO, apply. PART I Permit -Page 4 Permit No. COR-030000 A. COVERAGE UNDER THIS PERMIT (cont.) b) Local Agency Authority: This permit does not pre-empt or supersede the authority of local agencies to prohibit, restrict, or control discharges of storm.water to storm drain systems or other water courses within their jurisdiction. c) Permit Coverage Termination: When a site under a Qualifying Local Program has been finally stabilized, coverage under this permit is automatically terminated. d) Compliance with Qualifying Local Program: A construction site operator that has authorization to discharge under this permit under Part I.A.3 shall comply with the requirements of the Qualifying Local Program with jurisdiction over the site. e) Full Permit Applicability: The Division may require any operator within the jurisdiction of a Qualifying Local Program covered under this permit to apply for and obtain coverage under the full requirements of this permit. The operator must be notified in writing that an application for full coverage is required. When a permit certification under this permit is issued to an operator that would otherwise be covered under Part I.A.3 of this permit, the full requirements of this permit replace the requirements as per Part IA.3 of this permit, upon the effective date of the permit certification. A site brought under the full requirements of this permit must still comply with local stormwater management requirements, policies or guidelines as required by Part I.D.l.g of this permit. 4.

PAR.TI Permit -Page 6 PermitNo. COR-030000 If the new responsible party will not complete the reassignment form, the applicable portion of the permitted site may be removed from permit coverage upon written request to the Division if the permittee has no legal responsibility, through ownership or contract, for the construction activities at the portion of the site. In this case, the new owner or operator would be required to obtain permit coverage separately. 9. Sale of Residence t-0 Homeowners For residential construction only, when a residential lot has been conveyed to a homeowner and all criteria in paragraphs a through e, below, are met, coverage under this permit is no longer required and the conveyed lot may be removed from coverage under the permittee' s certification. At such time, the permittee is no longer responsible for meeting the terms and conditions of this permit for the conveyed lot, including the requirement to transfer or reassign permit coverage. The permittee remains responsible for inactivation of the original certification. a) The lot has been sold to the homeowner(s) for private residential use; b) the lot is less than one acre of disturbed area; c) all construction activity conducted by the perrnittee on the lot is completed; d) a certificate of occupancy (or equivalent) has been awarded to the home owner; and e) the SW:MP has been amended to indicate the lot is no longer covered by permit. Lots not meeting all of the above criteria require continued permit coverage. However, this permit coverage may be transferred (Part LA.7, above) or reassigned (Part LA.8, above) to anew owner or operator. 10. Permit Expiration Date Authorization to discharge under this general permit shall expire on June 30, 2012. The Division must evaluate and reissue this general permit at least once every five years and must recertify the permittee's authority to discharge under the general permit at such time. Therefore, a permittee desiring continued coverage under the general permit must reapply by March 31, 2012. The Division will initiate the renewal process; however, it is ultimately the permittee's responsibility to ensure that the renewal is submitted. The Division will determine if the permittee may continue to operate under the terms of the general permit. An individual permit may be required for any facility not reauthorized to discharge under the reissued general permit. 11. Individual Permit Criteria Various criteria can be used in evaluating whether or not an individual (or alternate general) permit is required instead of this general permit. This information may come from the application, SWMP, or additional information as requested by the Division, and includes, but is not limited to, the following: a) b) c) d) e) the quality of the receiving waters (i.e., the presence of downstream drinking water intakes or a high quality fishery, or for preservation of high quality water); the size of the construction site; evidence of noncompliance under a previous permit for the operation; the use of chemicals within the stormwater system; or discharges of pollutants of concern to waters for which there is an established Total Maximum Daily Load (TMDL). In addition, an individual permit may be required when the Division has shown or has reason to suspect that the storm.water discharge may contribute to a violation of a water quality standard. B. STORMW ATER MANAGEMENT PLAN (SWMP)-GENERAL REQUIREMENTS 1. A SWMP shall be developed for each facility covered by this permit.

Any discharge of hazardous material must be handled in accordance with the Division's Noncompliance Notification Requirements (see Part II.A.3 of the permit). 5. SWMP Requirements a) SWMP Preparation and Implementation: The SWMP shall be prepared prior to applying for coverage under the general permit, and certification of its completion submitted with the application. The SWMP shall be implemented prior to commencement of construction activities. The plan shall be updated as appropriate (see paragraph c, below), below). SWMP provisions shall be implemented until expiration or inactivation of permit coverage. b) SWMP Retention Requirements: A copy of the SWMP must be retained on site unless another location, specified by the permittee, is approved by the Division. c) SWMP Review/Changes: The permittee shall amend the SWMP: I) when there is a change in design, construction, operation, or maintenance of the site, which would require the implementation of new or revised BMPs; or 2) if the SWMP proves to be ineffective in achieving the general objectives of controlling pollutants in stormwater discharges associated with construction activity; or PART I Permit -Page 12 Permit No. COR-030000 D. TERMS AND CONDITIONS (cont.) 3) when BMPs are no longer necessary and are removed. SWMP changes shall be made prior to changes in the site conditions, except as allowed for in paragraph d, below. SWMP revisions may include, but are not limited to: potential pollutant source identification; selection of appropriate BMPs for site conditions; BMP maintenance procedures; and interim and final stabilization practices. The SWMP changes may include a schedule for further BMP design and implementation, provided that, if any interim BMPs are needed to comply with the permit, they are also included in the SWMP and implemented during the interim period. d) Responsive SW1\'1P Changes: SWMP changes addressing BMP installation and/or implementation are often required to be made in response to changing conditions, or when current BMPs are determined ineffective. The majority of SWMP revisions to address these changes can be made immediately with quick in-the-field revisions to the SWMP. In the less common scenario where more complex development of materials to modify the SWMP is necessary, SW.MP revisions shall be made in accordance with the following requirements: 1) the SWMP shall be revised as soon as practicable, but in no case more than 72 hours after the change( s) in BMP installation and/or implementation occur at the site, and 2) a notation must be included in the SWMP prior to the site change(s) that includes the time and date of the change(s) in the field, an identification of the BMP(s) removed or added, and the location(s) of those BMP(s). 6. Inspections Site inspections must be conducted in accordance with the following requirements and minim.um schedules. The required minimum inspection schedules do not reduce or eliminate the permittee' s responsibility to implement and maintain BMPs in good and effective operational condition, and in accordance with the SWMP, which could require more :frequent inspections. a) Minimum Inspection Schedule: The permittee shall, at a minimum, make a thorough inspection, in accordance with the requirements in I.D.6.b below, at least once every 14 calendar days. Also, post-storm event inspections must be conducted within 24 hours after the end of any precipitation or snowmelt event that causes surface erosion. Provided the timing is appropriate, the post-storm inspections may be used to fulfill the 14-day routine inspection requirement. A more :frequent inspection schedule than the minimum inspections described may be necessary, to ensure that BMPs continue to operate as needed to comply with the permit. The following conditional modifications to this Minimum Inspection Schedule are allowed: 1) Post-Storm Event Inspections at Temporarily Idle Sites -If no construction activities will occur following a storm event, post-storm event inspections shall be conducted prior to re-commencing construction activities, but no later than 72 hours following the storm event. The occurrence of any such delayed inspection must be documented in the inspection record. Routine inspections still must be conducted at least every 14 calendar days. 2) Inspections at Completed Sites/Areas-For sites or portions of sites that meet the following criteria, but final stabilization has not been achieved due to a vegetative cover that has not become established, the permittee shall make a thorough inspection of their stormwater management system at least once every month, and post- storm event inspections are not required. This reduced inspection schedule is only allowed if: i) all construction activities that will result in surface ground disturbance are completed; ii) all activities required for final stabilization, in accordance with the SWMP, have been completed, with the exception of the application of seed that has not occurred due to seasonal conditions or the necessity for additional seed application to augment previous efforts; and iii) the S WMP has been amended to indicate those areas that will be inspected in accordance with the reduced schedule allowed for in this paragraph. ( . ~--( -;~ ·.______:,- PART I Permit -Page 13 Permit No. COR-030000 D. TERMS AND CONDITIONS (cont.) 3) Winter Conditions Inspections Exclusion -Inspections are not required at sites where construction activities are temporarily halted, snow cover exists over the entire·site for an extended period, and melting conditions . posing a risk of surface erosion do not exist. This exception is applicable only during the period where melting conditions do not exist, and applies to the routine 14-day and monthly inspections, as well as the post-storm- event inspections. The following information must be documented in the inspection record for use of this exclusion: dates when snow cover occurred, date when construction activities ceased, and date melting conditions began. Inspections, as described above, are required at all other times. When site conditions make the schedule required in this section impractical, the permittee may petition the Division to grant an alternate inspection schedule. b) Inspection Requirements 1) Inspection Scope -The construction site perimeter, all disturbed areas, material and/or waste storage areas that are exposed to precipitation, discharge locations, and locations where vehicles access the site shall be inspected for evidence of, or the potential for, pollutants leaving the construction site boundaries, entering the stormwater drainage system, or discharging to state waters. All erosion and sediment control practices identified in the SWMP shall be evaluated to ensure that they are maintained and operating correctly. 2) Inspection Report/Records -The permittee shall keep a record of inspections. Inspection reports must identify any incidents of non-compliance with the terms and conditions of this permit. Inspection records must be retained for three years from expiration or inactivation of permit coverage. At a minimum, the inspection report must include: i) The inspection date; ii) Name(s) and title(s) of personnel making the inspection; iii) Location(s) of discharges of sediment or other pollutants from the site; iv) Location(s) ofBMPs that need to be maintained; v) Location(s) ofBMPs that failed to operate as designed or proved inadequate for a particular location; vi) Location(s) where additional BMPs are needed that were not in place at the time of inspection; vii) Deviations from the minimum inspection schedule as provided in Part I.D.6.a above; vii) Description of corrective action for items iii, iv, v, and vi, above, dates corrective action(s) taken, and measures taken to prevent future violations, including requisite changes to the SWMP, as necessary; and viii) After adequate corrective action( s) has been taken, or where a report does not identify any incidents requiring corrective action, the report shall contain a signed statement indicating the site is in compliance with the permit to the best of the signer's knowledge and belief. c) Required Actions Following Site Inspections-Where site inspections note the need for B1v1P maintenance activities, BMPs must be maintained in accordance with the SWMP and Part I.D.7 of the permit. Repair, replacement, or installation of new BMPs determined necessary during site inspections to address ineffective or inadequate BMPs must be conducted in accordance with Part I.D.8 of the permit. SWMP updates required as a result of deficiencies in the SWMP noted during site inspections shall be made in accordance with Part I.D.5.c of the permit. 7. BMP Maintenance All erosion and sediment control practices and other protective measures identified in the SWMP must be maintained in effective operating condition. Proper selection and installation ofBMPs and implementation of comprehensive Inspection and Maintenance procedures, in accordance with the SWMP, should be adequate to meet this condition. BMPs that are not adequately maintained in accordance with good engineering, hydro logic and pollution control practices, including removal of collected sediment outside the acceptable tolerances of the BMPs, are considered to be no longer operating effectively and must be addressed in accordance with Part I.D.8, below. A specific timeline for implementing maintenance procedures is not included in this permit because BMP maintenance is expected to be proactive, not responsive. Observations resultii-ig in Bl\t1P maintenance activities can be made during a site inspection, or during general observations of site conditions. · PART I Permit -Page 14 Permit No. COR-030000 D. TERMS AND CONDITIONS (cont.) 8. Replacement and Failed BMPs Adequate site assessment must be performed as part of comprehensive Inspection and Maintenance procedures, to assess the adequacy of BMPs at the site, and the necessity of changes to those B.MPs to ensure continued effective performance. Where site assessment results in the determination that new or replacement B:rvIPs are necessary, the BMPs must be installed to ensure on-going implementation ofB11Ps as per Part ID2. Where BMPs have failed, resulting in noncompliance with Part I.D.2, they must be addressed as soon as possible, immediately in most cases, to minimize the discharge of pollutants. When new BNIPs are installed or B:rvIPs are replaced, the SWMP must be updated in accordance with Part LD.5(c). 9. Reporting No scheduled reporting requirements are included in this permit; however, the Division reserves the right to request that a copy of the inspection reports be submitted. 10.. SWMP Availabilitv A copy of the SWMP shall be provided upon request to the Division, EPA, or any local agency in charge of approving sediment and erosion plans, grading plans or stormwater management plans, and within the time frame specified in the request. If the SWMP is required to be submitted to any of these entities, it must include a signed certification in accordance with Part I.F.l of the permit, certifying that the SWNIP is complete and meets all permit requirements. All SWMPs required under this permit are considered reports that shall be available to the public under Section 308(b) of the CW A and Section 61.5( 4) of the Colorado Discharge Permit System Regulations. The permittee shall make plans available to members of the public upon request. However, the permittee may claim any portion of a SWMP as confidential in accordance with 40 CFR Part 2. 11. Total Maximum Dailv Load (TlVIDL) If a TMDL has been approved for any waterbody into which the permittee discharges, and stormwater discharges associated with construction activity have been assigned a pollutant-specific Wasteload Allocation (WLA) lm.der the TMDL, the Division will either: . a) Ensure that the WLA is being implemented properly through alternative local requirements, such as by a municipal storm.water permit; or b) Notify the permittee of the WLA, and amend the permittee's certification to add specific B.MPs and/or other requirements, as appropriate. The permittee may be required to do the following: I) Under the permittee' s SWMP, implement specific management practices based on requirements of the WLA, and evaluate whether the requirements are being met through implementation of existing stormwater Bl\1Ps or if additional Bl\1Ps are necessary. Document the calculations or other evidence that show that the requirements are expected to be met; and 2) If the evaluation shows that additional or modified Bl\1Ps are necessary, describe the type and schedule for the BMP additions/revisions. Discharge monitoring may also be required. The permittee may maintain coverage under the general permit provided they comply with the applicable requirements outlined above. The Division reserves the right to require individual or alternate general permit coverage. ( cf E. PARTI Permit -Page 15 Permit No. COR-030000 ADDITIONAL DEFINITIONS For the purposes of this permit: 1. Best Management Practices (B:M.Ps): schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce the pollution of waters of the State. BMPs also include treatment requirements, operating procedures, pollution prevention, and practices to control site runoff, spillage or leaks, waste disposal, or drainage from material storage. 2. Dedicated asphalt plants and concrete plants: portable asphalt plants and concrete plants that are located on or adjacent to a construction site and that provide materials only to that specific construction site. 3. Final, stabilization: when all ground surface disturbing activities at the site have been completed, and uniform vegetative cover has been established with an individual plant density of at least 70 percent of pre-disturbance levels, or equivalent permanent, physical erosion reduction methods have been employed. For purposes of this permit, establishment of a vegetative cover capable of providing erosion control equivalent to pre-existing conditions at the site will be considered final stabilization. 4. Municipal separate storm sewer system: a conveyance or system of conveyances (including: roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels, or storm drains), owned or operated by a State, city, town, county, district, or other public body (created by state law), havingjurisdiction over disposal of sewage, industrial waste, stormwater, or other wastes; designed or used for collecting or conveying stormwater. 5. Operator: the entity that has day-to-day supervision and control of activities occurring at the construction site. This can , .. be the owner, the developer, the general contractor or the agent of one of these parties, in some circumstances. It is anticipated that at different phases of a construction project, different types of parties may satisfy the defmition of 'operator' and that the permit may be transferred as the roles change. 6. Outfall: a point source at the point where storm.water leaves the construction site and discharges to a receiving water or a storm.water collection system. 7. Part of a larger common plan of development or sale: a contiguous area where multiple separate and distinct construction activities may be talcing place at different times on different schedules. 8. Point source: any discernible, confined and discrete conveyance from which pollutants are or may be discharged. Point source discharges of stormwater result from structures which increase the imperviousness of the ground which acts to collect nm.off, with runoff being conveyed along the resulting drainage or grading pattern. 9. Pollutant: dredged spoil, dirt, slurry, solid waste, incinerator residue, sewage, sewage sludge, garbage, trash, chemical waste, biological nutrient, biological material, radioactive material, heat, wrecked or discarded equipment, rock, s.and, or any industrial, municipal or agricultural waste. 10.

MANAGEMENT REQUIREMENTS 1. Amending a Permit Certification The permittee shall inform the Division (Permits Section) in writing of changes to the information provided .in the permit application, includ.ing the legal contact, the project legal description or map originally submitted with the application, or the planned total disturbed acreage. The permittee shall furnish the Division with any plans and specifications which the Division deems reasonably necessary to evaluate the effect on the discharge and receiving stream. If applicable, this notification may be accomplished through submittal of an application for a CDPS process water permit authorizing the discharge. The SWMP shall be updated and implemented prior to the changes (see Part I.D.5.c). Any discharge to the waters of the State from a point source other than specifically authorized by this permit or a different CDPS permit is prohibited. 2. Special Notifications -Definitions a) Spill: An unintentional release of solid or liquid material which may cause pollution of state waters. b) Upset: An exceptional incident in which there is unintentional and temporary noncompliance with permit discharge limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or careless or improper operation. 3. Noncompliance Notification a) The permittee shall report the following instances of noncompliance: 1) Any noncompliance which may endanger health or the environment; 2) Any spill or discharge of hazardous substances or oil which may cause pollution of the waters of the state. 3) Any discharge of storm.water which may cause an exceedance of a water quality standard. b) For all instances of noncompliance based on environmental hazards and chemical spills and releases, all needed information must be provided orally to the Colorado Department of Public Health and Environment spill reporting line (24-hour number for environmental hazards and chemical spills and releases: 1-877-518-5608) within 24 hours from the time the permittee becomes aware of the circumstances. For all other instances of noncompliance as defined in this section, all needed information must be provided orally to the Water Quality Control Division within 24 hours from the time the permittee becomes aware of the circumstances. For all instances of noncompliance identified here, a written submission shall also be provided within 5 calendar days of the time the permittee becomes aware of the circumstances. The written submission shall contain a description of: 1) The noncompliance and its cause; 2) The period of noncompliance, including exact dates and times, and if the noncompliance has not been corrected, the anticipated time it is expected to continue; 3) Steps taken or planned to reduce, eliminate, and prevent reoccurrence of the .noncompliance. A. MANAGEMENT REQUIREMENTS (cont.) 4. Submission of Incorrect or Incomplete Information Where the permittee failed to submit any relevant facts in a permit application, or submitted incorrect information-in a permit application or report to the Division, or relevant new information becomes available, the permittee shall promptly submit the relevant application information which was not submitted or any additional information needed to-correct any erroneous information previously submitted. 5. Bypass a) A bypass, which causes effluent limitations (i.e., requirements to implement BMPs in accordance with Parts I.B.3 and LD.2 of the permit) to be exceeded is prohibited, and the Division may take enforcement action against a permittee for such a bypass, unless: 1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage; 2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities (e.g., alternative BivIPs), retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if the permittee could have installed adequate backup equipment (e.g., implemented additional BMPs) to prevent a bypass which occurred during normal periods of equipment downtime or preventative maintenance; and 3) The permittee submitted notices as required in "Non-Compliance Notification," Part II.A3. 6. Upsets a) Effect of an Upset: An upset constitutes an affirmative defense to an action brought for noncompliance with permit limitations and requirements if the requirements of paragraph b of this section are met. (No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is fmal administrative action subject to judicial review.) b) Conditions Necessary for a Demonstration of Upset: A permittee who wishes to establish the affirmative defense of upset shall demonstrate through properly signed contemporaneous operating logs, or other relevant evidence that: c) 1) An upset occurred and that the perrnittee can identify the specific cause( s) of the upset; 2) The permitted facility was at the time being properly operated; 3) The perrnittee submitted notice of the upset as required in Part II.A3. of this permit (24-hour notice); and 4) The permittee complied with any remedial measures required under 40 CFR Section 122.41(d) of the federal regulations or Section 61.8(3)(h) of the Colorado Discharge Permit System Regulations.

The term "construction activity" includes ground suiface disturbing activities, including, but not limited to, clearing, grading, excavation, demolition, installation of new or improved haul and access roads, staging areas, stockpiling of fill materials, and borrow areas. "Stormwater" is precipitation-induced surface runoff. This rationale will explain the background of the Stormwater program, activities which are covered under this permit, how to apply for coverage under this permit, and the requirements of this permit. The forms discussed in the rationale and permit are available on the Water Quality Control Division's website at: www.cdphe.siate.eo.us/.wq/PermitsUnit II. CHANGES IN THIS GENERAL PER.lv!IT Several notable changes from the previous General Permit for Construction Activities have been incorporated into this permit. Significant changes are listed below. Numerous other minor changes were made for clarification purposes only. A. Authoritv to Discharge This section has been restructured to list all of the types of activities covered by this permit, and to be consistent with the definition of" construction activity." The definition of construction activity has been expanded to provide clarification. See Part I.A. I of the permit. PART II Permit -Page 24 Permit No. COR-030000 II. CHANGES IN THIS GENERAL PERMIT (cont.) B. Authoritv to Discharge -Oil and Gas Constntction This section has been added, to take into account a regulatory change. The federal Energy Policy Act of 2005 exempts nearly all oil and gas construction activities from federal requirements under the Clean Water Act's NP DES stormwater discharge permit program. In January 2006, the Colorado Water Quality Control Commission held a hearing to determine what effects, if any, the change in federal law would have upon Colorado's stormwater regulations. The Commission determined that oil and gas construction sites in Colorado that disturb one or more acres are still required to be covered under Colorado's stormwater permitting regulations (Colorado Discharge Permit System (CDPS) regulations (5CCR 1002-61)). In practice, oil and gas construction sites have the same requirements under this permit as do other types of construction. However, this permit contains some references to the federal Clean Water Act; generally these references are not applicable to oil and gas construction sites to the extent that the references are limited by the federal Energy Policy Act of 2005. See Part LA. I (b) of the permit. C. Application Requirements The permit application requirements have changed slightly, including the addition of an email address, if available. See Part IA.4(b). The applicant must be either the owner and/or operator of the construction site. An operator at a construction site that is not covered by a certification held by an appropriate entity may be held liable for operating without the necessary permit coverage. D. Temvorarv Coveraf!e Part IA.5(d) of the previous permit (effective July 1, 2002) dealt with temporarily covering a facility under the general permit even if an individual permit is more appropriate. This permit section essentially duplicated the previous section (see Part I.A.5(c)), and so it has been deleted. E. Reassignment of Permit Coverage Procedures have been added to clarifj; the requirements for the transfer of coverage of specific portions of a permitted site to a second party. See Section VIII.I.3 of the rationale and Part IA.8 of the permit. F. Individual Permit Criteria This section has been modified to include situations involving a Total Maximum Daily Load (TMDL). See Part I.A.I I of the permit. G. Stormwater Management Plan (SWMP) The Stormwater J1anagement Plan section has been divided into two parts: Stormwater Management Plan (SWMP) -General Requirements, which provides the basic framework and general requirements for the SWMP, and Stormwater Management Plan (SWMP) -Contents, which specifically identifies each item that must be addressed in the SWMP. See Parts 1.B and IC of the permit. H. Stormwater 1\1anagement Plan (SWMP) -General Requirements The SWMP General Requirements section has been modified to require that the SWMP be updated in accordance with Parts ID.5(c) and I.D.5(d) of the permit (SWlvlP Review/Changes). This additional requirement ensures that the SWMP provisions reflect current site conditions. See Part 1.B.2(c) of the permit. ( :"-. l. _ _( PART II Permit -Page 25 Permit No. COR-030000 II. CHANGES IN THIS GENERAL PERMIT (cont.) I. Stormwater Management Plan (SWMP) -Contents The SWMP Contents section has been modified. Some of the changes are limited to organization of information, which does not require modification of an existing permittee 's current SWMP. Most of the SWMP changes involve either clarifications, reformatting, or taking recommendations from the Division's SWMP guide and making them permit requirements (e.g., vehicle tracking controls, BMP installation specifications). If an existing permittee (i.e., those with permit coverage before June 30, 2007) followed the recommendations in the SWMP guide {Appendix A of the permit application), then their SWMP will presumabZv meet the new requirements. However, for any existing permittees who did not follow the applicable SWMP guide recommendations, their SMWP must be amended to include the new required items: -SWMP Administrator -Identification of potential pollutant sources -Best Management Practices descriptions and installation specifications, including dedicated concrete or asphalt batch plants; vehicle tracking control,· and waste management and disposal (including concrete washout activities). For existing permittees, any SWMP changes based on the change in permit requirements must be completed by October 1, 2007. The plan is not to be submitted to the Division unless requested, but must be available on site as outlined in Part I.D.5(b) of the permit. The BMP requirement clarifications included in this renewed permit in no way imply that adequate BMPs to address all pollutant sources at a permitted site were not required in previous permits. The revised requirements are intended onZv to better clarifY SWMP content requirements and provide improved direction to permittees. The SWMP changes are listed below. All new applicants (after June 30, 2007) for permit coverage for their sites must fully comply with the new SWMP organization, plan requirements, and implementation. 1. Site Description: The requirement to provide an estimate of the nm-off coefficient has been removed. The run-off coefficient as currently utilized in the SWMP may not contribute sufficiently to permit compliance to justify the effort in determining accurate values. See Part LC. l of the permit. However, the Division still encourages use of the coefficient as needed to adequately evaluate site-specific BMP selection and design criteria (e.g., pond capacities, BMP location, etc.) See Section C.2 of the SWMP guidance {Appendix A of the permit application). 2. Site Map: The requirement to identifY boundaries of the 100-year flood plain has been removed. The boundaries as current£v utilized in the SWMP may not contribute sufficiently to permit compliance to justifY the effort in determining their location. See Part l.C.2 of the permit. 3. Stormwater Management Controls: This section has been modified to require identification of a SWMP Administrator and all potential pollutants sources in the SWMP. See Part 1.C.3 of the permit. a) The SWMP Administrator is a specific individual(s), position or title who is responsible for the process of developing, implementing, maintaining, and revising the SWMP. This individual serves as the comprehensive point of contact for all aspects of the facility's SWMP. This· requirement may necessitate changes to existing permittees' SWMPs. PART II Permit -Page 26 Permit No. COR-030000 II. CHANGES IN THIS GENERAL PERMIT (cont.) b) The requirement to identifj; Potential Pollutant Sources has been expanded to include more details for the evaluation of such sources. This evaluation allows for the appropriate selection of BMPs for implementation at a facility or site. Additionally, this section was added to be consistent with the SWMP guide. This requirement may necessitate changes to existing permittees' SWMPs. c) Best Management Practices (BMPs) for Stormwater Pollution Prevention: This section was modified to require the following items to be addressed in the SW'MP. These requirements may necessitate changes to existing permittees' SWMPs. This section also requires that the SWMP provide installation and implementation specifications for each BAtf P identified in the SWMP. For structural BMPs, in most cases, this must include a technical drawing to provide adequate installation specifications. See Part I.C.3(c). i) Dedicated concrete or asphalt batch plants. This section requires that the practices used to reduce the pollutants in stormwater discharges associated with dedicated concrete or asphalt batch plants be identified in the SWMP. (Coverage under the construction site SWMP and permit is not required for batch plants if they have alternate CDPS permit coverage.) ii) Vehicle tracking control. This section requires that practices be implemented to control sediment from vehicle tracking, and that all such practices implemented at the site be clearZv described in the SWMP. iii) Waste management and disposal. This section requires that the practices implemented at the site to control stormwater pollution from construction site waste, including concrete washout activities, be clearly described in the SWMP. It also requires that concrete washout activities be conducted in a manner that does not contribute pollutants to surface waters or storm water runoff iv) Concrete Washout Water. Part ID.3(c) of the permit has been revised to conditionally authorize discharges to the ground of concrete wash water from washing of tools and concrete mixer chutes when appropriate BMPs are implemented. The permit prohibits the discharge of concrete washout water to surface waters and to storm sewer systems. Part IC.3(c)(7) of the permit requires that BMPs be in place to prevent surface discharges of concrete washout water from the site. The use of unlined pits to contain concrete washout water is a common practice in Colorado. The Division has further evaluated the need for a permit for discharge of concrete washout water to the ground. The Division has determined that the use of appropriate BJvf Ps for on-site washing of tools and concrete mixer chutes would prevent any significant discharge to groundwater. BMPs to protect groundwater are required by Part I.C.3(c)(7) of the permit. Because pH is a pollutant of concern for washout activities, the soil must have adequate buffering capadty to result in protection of the groundwater standard, or a liner/containment must be used. The following management practices are recommended to prevent an impact from unlined pits to groundwater: (1) the use of the washout site should be temporary (less than 1 year), and (2) the washout site should be not be located in an area where shallow groundwater may be present, such as near natural drainages, springs, or wetlands. ((.~ . ./!'' '·-.~· ··. ~.w PART II Permit -Page 27 ,r--Permit No. COR-030000 \ ____ j II. CHANGES IN THIS GENERAL PERMIT (cont.) Where -adequate management practices are not followed to protect groundwater quality, the Department may require discharges to unlined pits to cease, or require the entity to obtain alternate regulatory approval through notice from either the Water Quality Control Division or the Hazardous Materials and Waste Management Division. In addition, Part 1.D.l (b) of the permit has been revised to clearly state that the permit does not authorize on-site permanent disposal of concrete washout waste, only temporary containment of concrete washout water from washing of tools and concrete mixer chutes. Upon termination of use of the washout site, accumulated solid waste, including concrete waste and any contaminated soils, must be removed from the site to prevent on-site disposal of solid waste. v) Construction Dewatering. Part I.D.3(d) of the permit has been revised to conditionally authorize discharges to the ground of water from construction dewatering activities when appropriate BMPs are implemented. The permit does not authorize the discharge of groundwater from construction dewatering to swface waters or to storm sewer systems. Part 1.C.3(c)(8) of the permit requires that BMPs be in place to prevent surface discharges. The permittee may apply for coverage under a separate CDPS discharge permit, such as the Construction Dewatering general permit, if there is a potential for discharges to surface waters. The Division has determined that potential pollutant sources introduced into groundwater from construction dewatering operations do not have a reasonable potential to result in exceedance of groundwater standards when the discharge is to the ground. The primary pollutant of concern in uncontaminated groundwater is sediment. Although technology- based standards for sediment do exist in 5 CCR 1002-41, the discharge of sediment to the ground as part of construction dewatering does not have the reasonable potential to result in transport of sediment to the groundwater table so as to result in an exceedance of those standards. For a discharge of water contaminated with other pollutants that are present in concentrations that may cause an exceedance of groundwater standards, separate CDPS discharge permit coverage is required. Contaminated groundwater may include that contaminated with pollutants from a landfill, mining activity, industrial pollutant plume, underground storage tank, or other source of human-induced groundwater pollution and exceeding the State groundwater standards in Regulations 5 CCR 1002-41and42. J. Terms and Conditions. General Limitations and Design Standards This section reiterates the requirement that facilities select, install, implement, and maintain appropriate BMPs, following good engineering, hydrologic and pollution control practices. In addition, requirements for protection of water quality standards (see Part I.D.l.(a) of the permit) and requirements to adequately design BMPs to prevent pollution or degradation of State waters (see Part 1.D.2 of the permit) have been revised and are fully discussed in Part 111.B of the rationale, below. Additional language was also added to Section 111.B of the rationale further clarifying the expectations for compliance with this permit. 1. Management o(Site Waste This section has been modified to clarify that on-site waste must be properly managed to prevent potential pollution of State waters, and that this permit does not authorize on-site waste disposal. Solid waste disposal is regulated by the Hazardous Materials and Waste Management Division. PART II Permit -Page 28 Permit No. COR-030000 II. CHANGES IN THIS GENERAL PERMIT (cont.) K. Terms and Conditions. SWMP Requirements 1. SWMP Review/Changes: This section now requires that when changes are made to site conditions, the SWMP must be revised immediately, except for some BMP description changes which conditionally may occur within 72 hours. This requirement is included to both ensure that the SWMP be kept accurate and up-to-date, and to clarifY that stormwater management at a site typic.ally should be proactive instead of responsive, and be integrated into site management to ensure it is calibrated with those changes. The section was also clarified to state that only changes in site conditions that do not require new or modified BMPs do not need to be addressed in the SWMP. See Part ID.5(c) of the permit. 2. SWMP Certification: The previous permit was unclear on a requirement that the copy of SWMP that remains at the facility had to be signed in accordance with permit signatory requirements. This requirement has been deleted. The signatory requirement of Part IF. I only applies to the SWMP if it is to be submitted to the Division or to EPA. See Part 1.F. l of the permit. L. Terms and Conditions, Post-Storm Inspections The previous permit required post-storm inspections, but did not specifY the timing of inspections. This section now requires that post-storm event inspections general(v be conducted within 24 hours of the event. An alternative timeline has been allowed, onlv for sites where there are no construction activities occurring following a storm event. For this condition, post-storm event inspections shall instead be conducted prior to commencing construction activities, but no later than 72 hours following the storm event, and the delay noted in the inspection report. Any exception from the minimum inspection schedule is temporary, and does not eliminate the requirement to perform routine maintenance due to the effects of a storm event, including maintaining vehicle trading controls and removing sediment from impervious areas. In many cases, maintenance needs will require a more frequent inspection schedule than the minimum inspections required in the permit, to ensure that BMPs continue to operate as needed to comply with the permit. See Part I.D.6(a) of the permit. M Terms and Conditions. Inspections I. The Winter Conditions Inspection Exclusion section has been modified to include documentation requirements for this exclusion. See Part l.D.6(a) of the permit. The Inspection Scope has been modified to include the requirement to inspect waste storage areas during inspections conducted in accordance with the permit. See Part ID.6(b) of the permit. 2. The requirements for sites to qualifY for reduced inspection frequencies for completed sites have been slightly modified (see Part J.D.6(a)(2) of the permit,). The requirement now is that only construction activities that disturb the ground swface must be completed. Construction activities that can be ·conducted without disturbance of the ground suiface; for example, interior building construction, and some oil well activities, would not prohibit a site from otherwise qualifYingfor the reduced inspection frequency. In addition, the requirement for the site to be prepared for final stabilization has been slightly modified to allow for sites that have not yet been seeded to qualify, as long as the site has otherwise been prepared for final stabilization, including completion of appropriate soil preparation, amendments and stabilization practice. This will allow for sites with seasonal seeding limitations or where additional seed application may be needed in the future to still qualify. ·1 PART II Permit -Page 29 Permit No. COR-030000 II. CHANGES IN THIS GENERAL PERMIT (cont.) 3. The Inspection Report/Records section (PartLD.6(b)(2)) was added to clarify requirements for inspection reports generated during an inspection conducted in accordance with Part 1.D.6 of the permit. Inspection reports must be signed by the inspector, or the individual verifying the corrective action indicated in the inspection report, on behalf of the permittee. Inspection reports are not typically required to be submitted to the Division, and therefore, are not required to be signed and certified for accuracy in accordance with Part 1.F.l of the permit. However, any inspection reports that are submitted to the Division must follow the signatory requirements contained in that section. N. Terms and Conditions. Maintenance, Repair. and Replacement of Control Practices .These sections have been added to clarify requirements for maintaining the BMPs identified in the SWMP and for addressing ineffective or failed BMPs. BMP maintenance and site assessment to determine the overall adequacy of stormwater quality management at the site must occur proactively, in order to ensure adequate control of pollutant sources at the site. In most cases, if BMPs are already not operating effectively, or have failed, the issue must be addressed immediately, to prevent discharge of pollutants. See Parts ID. 7 and I.D.8 of the permit. 0. Total Maximum Dailv Load (TMDL) A section on TMDLs has been added. This section gives a general outline of the additional requirements that may be imposed by the Division if the facility discharges to a waterbody for which a stormwater-related TMDL is in place. See Section VIII. C of the rationale and Part LD.11 of the permit. P. Additional Definitions Part 1.E of the permit has been modified to remove the definition of nmoff coefficient, as it is no longer a permit requirement. The definition for state waters has also been deleted, but can be found in Regulation 61. Q. Changes in Discharge The section on the types of discharge or facility changes that necessitate Division notification has been clarified. See Part II.A.I of the permit. R. Non-Compliance Notification The section on notification to the Division regarding instances of non-compliance has been amended to clarify which types of noncompliance require notification. See Part II.A.3 of the permit. S. Short Term Certifications The previous permit allowed small short-term construction activities to be authorized for a predetermined period from 3 to 12 months, and then automatically expire (an inactivation request did not need to be submitted). The issuance of these certifications has led to significant confusion and incidents of noncompliance resulting from permittees unintentionally letting their certifications expire prior to final stabilization, as well as issues regarding billing. Therefore, the provisions for short-term certifications have been deleted. T. Bvpass The Division has revised the Bypass conditions in Part IIA.5 of the permit to be consistent with the requirements of Regulation 61.8(3)(i). The revised language addresses under what rare occurrences BMPs may be bypassed at a site. PART II Permit -Page 30 Permit No. COR-030000 III. BACKGROUND As required under the Clean Water Act amendments of 1987, the Environmental Protection Agency (EPA) has established aframeworkfor regulating municipal and industrial stormwater discharges. This framework is under the National Pollutant Discharge Elimination System (NPDES) program (Note: The Colorado program is referred to as the Colorado Discharge Permit System, or CDPS, instead of NP DES.) The Water Qua/tty Control Division ("the Division") has stormwater regulations (5CCR 1002-61) in place. These regulations require specific "types of industrial facilities that discharge stormwater associated with industrial activity (industrial stormwater), to obtain a CDPS permit for such discharge. The regulations specifically include construction activities that disturb one acre of land or more as industrial facilities. Construction activities that are part of a larger common plan of development which disturb one acre or more over a period of time are also included. A. General Permits The Division has determined that the use of general permits is the appropriate procedure for handling most of the thousands of industrial stormwater applications within the State. B. Permit Requirements This permit does not impose numeric e.ffl.uent limits or require submission of ejjl.uent monitoring data in the permit application or in the permit itself. The permit instead imposes practice-based e.ffl.uent limitations for stormwater discharges through the requirement to develop and implement a Stormwater Management Plan (SWMP). The narrative permit requirements include prohibitions against discharges of non-stormwater (e.g., process water). See Part LD.3 of the permit. The pennit conditions for the SWMP include the requirement for dischargers to select, implement and maintain Best Management Practices (BlvfPs) at a permitted construction site that adequate~v minimize pollutants in the discharges to assure compliance with the terms and conditions of the permit. Part l.D.2 of the permit includes basic design standards for BMPs implemented at the site. Facilities must select, install, implement, and maintain appropriate BMPs, following good engineering, hydrologic and pollution control practices. BMPs implemented at the site must be adequately designed to control all potential pollutant sources associated with construction activiry to prevent pollution or degradation of State waters. Pollution is defined in CDPS regulations (5CCR 1002-61) as man-made or man-induced, or natural alteration of the physical, chemical, biological, and radiological integri"ty of water. Utilizing industry-accepted standards for BMP selection that are appropriate for the conditions and pollutant sources present will "typically be adequate to meet these criteria, since construction BMPs are intended to prevent the discharge of all but minimal amounts of sediment or other pollutants that would not result in actual pollution of State waters, as defined above. However, site-specific design, including ongoing assessment of BMPs and pollutant sources, is necessary to ensure that BMPs operate as intended. The permit further requires that stormwater discharges from construction activities shall not cause, have the reasonable potential to cause, or measurably contribute to an excursion above any water qualify standard, including narrative standards for water qualify. This condition is the basis for all CDPS Discharge permits, and addresses the need to ensure that waters of the State maintain adequate water qualiry, in accordance with water qualify standards, to continue to meet their designated uses. It is believed that, in most cases, B1\1Ps can be adequate to meet applicable water qualiry standards. If water qualify impacts are noted, or the Division otherwise determines that additional permit requirements are necessary, they are "typical~v imposed as follows: I) at the renewal of this general permit or through a general permit specific to an industrial sector (if the issue is sector-based); 2j through direction from the Division based on the implementation of a TMDL (if the issue is watershed-based); or 3) if the issue is site-specific, through a revision to the certification from the Division based on an inspection or SWMP review, or through an individual permit. PART II Permit -Page 31 Permit No. COR-030000 III. BACKGROUND (cont.) Some construction sites may be required to comply with a Qualifying Local Program in place of meeting several of the specific requirements in this permit. Sites covered by a Qualifying Local Program may not be required to submit an application for coverage or a notice of inactivation and may not be required to pay the Division's annual fee. See Section VII of the rationale. C. Violations/Penalties Dischargers of stormwater associated with industrial activity, as defined in the CDPS regulations (5CCR 1002-61), that do not obtain coverage under this or other Colorado general permits, or under an individual CDPS permit regu,lating industrial stormwater, will be in violation of the Federal Clean Water Act and the Colorado Water Quality Control Act, 2 5-8-101. For facilities covered under a CDPS permit, failure to comply with any CDPS permit requirement constitutes a violation. As of the time of permit issuance, civil penalties for violations of the Act or CDPS permit requirements may be up to $10,000 per day, and criminal pollution of state waters is punishable by fines of up to $2 5, 000 per day. IV. STORMWATER DISCHARGES ASSOCIATED WITH CONSTRUCTION ACTIVITY The stormwater regulations (CDPS regulations (5CCR 1002-61)), require that stormwater discharges associated with certain industrial activities be covered under the permit program. Construction activity that disturbs one acre or more during the life of the project is specifically included in the listed industrial activities. This permit is intended to cover most stormwater discharges from construction facilities required by State regulation to obtain a permit. A. Construction Activitv Construction activity includes ground suiface disturbing activities including, but not limited to, clearing, grading, excavation, demolition, installation of new or improved haul and access roads, staging areas, stockpiling of.fill materials, and dedicated borrow/fill areas. Construction does not include routine maintenance to maintain original line and grade, hydraulic capacity, or original purpose of the facility. (The maintenance exclusion is intended for projects such as road resuifacing, and where there will be less than one acre of additional ground disturbed. Improvements or upgrades to existing facilities or roads, where at least one acre is disturbed, would not qualify as "routine maintenance. ") Definitions of additional terms can be found in Part J.E of the permit. Stormwater discharges from all construction activity require permit coverage, except for operations that result in the disturbance of less than one acre of total land area and which are not part of a larger common plan of development or sale. A "larger common plan of development or sale" is a contiguous area where multiple separate and distinct construction activities may be taking place at different times on d[(ferent schedules. B. Tvpes o(Discharges/Activities Covered 1. Stormwater: This permit is intended to cover most new or existing discharges composed entirely of stormwater from constmction activities that are required by State regu.lation to obtain a permit. This includes stormwater discharges associated with areas that are dedicated to producing earthen materials, such as soils, sand, and gravel, for use at a single construction site. These areas may be located at the construction site or at some other location. This permit does not authorize the discharge of mine water or process water from borrow areas. This permit may also cover stormwater discharges associated with dedicated asphalt plants and concrete plants located at a specific construction site. PART II Permit -Page 32 Permit No. COR-030000 IV. STORMWATER DISCHARGES ASSOCIATED WITH CONSTRUCTION ACTIVITY (cont.) 2. Process water: Under certain restrictions? discharges to the ground from construction dewatering, and from concrete washout activities, are also covered (see Parts IC.3{c){7), I.C.3(c)(8), I.D.3(c) and I.D.3(d) of the permit). C. Tvpes o(Activities NOT Covered 1. Stormwater: Aside from the sources listed in subparagraph B.1, above, this permit does not cover stormwater discharged from construction sites that is mixed with stormwater from other types of industrial activities, or process water of any kind. Other types of industrial activities that require stormwater discharge permits pursuant to different sections of the regulations (Regulation 5 CCR 1002-61, Section 61.2(e)(ii~)(A-L K)], are not covered by this permit. 2. Process water: This permit also does not cover any discharge of process water to swface waters. If the construction activity encounters groundwater, in order to discharge this groundwater to swface waters, a Construction Dewatering Discharge Permit (permit number COG-070000) must also be obtained. An application for this permit can be obtained from the Division at the address listed in Part I.A.4(a) of the permit, or at the website in Section I of the rationale. V. COVERAGE UNDER THIS GENERAL PERMIT Under this general permit, owners or operators of stormwater discharges associated with construction activity may be granted authorization to discharge stormwater into waters of the State of Colorado. This includes stormwater discharges associated with industrial activity ji-om areas that are dedicated to producing earthen materials, such as soils, sand and gravel, for use at a single construction site, and dedicated asphalt plants and dedicated concrete plants. This permit does not pre-empt or supersede the authority of other local, state or federal agencies to prohibit, restrict or control discharges of stormwater to storm drain systems or other water courses within their jurisdiction. Authorization to discharge under the permit requires submittal of a completed application form and a certification that the SWMP is co_mplete, unless the site is covered by a Qualifying Local Program. Upon receipt of all required information, the Division may allow or disallow coverage under the general permit. VI. APPLICATION AND CERTIFICATION At least ten days prior to the commencement of construction activities, the owner or operator of the construction site shall submit an original completed application which includes the signed certification that the SWMP is complete. Original signatures are required for the application to be considered complete. For small construction sites only, if the site is covered by a Qualifying Local Program (see below), submittal of an application is not required. For the purposes of this permit, the "operator" is the person who has day-to-day control over the project. This can be the own.er, the developer, the general contractor or the agent of one of these parties, in some circumstances. At different times during a construction project, different types of parties may satisfy the definition of "operator" and the certification may be transferred as roles change. (Note -Under the Federal regulations, this application process is refen·ed to as a Notice of Intent, or NOI For internal consistency with its current program, the Division will continue to use the term "application. ")A summary of the permit application requirements is found in the permit at Part LA.4(b). If coverage under this general permit is appropriate, then a certification will be developed and the applicant will be certified under this general permit. PART II Permit -Page 33 Permit No. COR-030000 VII. QUALIFYING LOCAL PROGRAMS For stormwater discharges associated with small constntction activity (i.e., one to five acre disturbed area sites), the permit includes conditions that inc01porate approved qualifying local erosion and sediment control program (Qualifying Local Program) requirements by reference. A Qualifying Local Program is a municipal stormwater program for stormwater discharges associated with small construction activity that has been formally approved by the Division. The requirements for Qualifying Local Programs are outlined in Part 61.8(12) of the Colorado Discharger Permit System Regu.lations (also see the Division's "Qualifying Local Programs for Small Construction Sites -Application Guidance"). Such programs must impose requirements to protect water quality that are at least as stringent as those required in this permit. A. Approval Termination A Qualifying Local Program may be terminated by either the Division or the municipality. Upon termination of Division approval of a Qualifying Local Program, any small construction activity required to obtain permit coverage under Section 61.3(2)(h) of the CDPS regu.lations (5CCR 1002-61), shall submit an application form as provided by the Division, with a certification that the Stormwater Management Plan (SWMP) is complete as required by Part l.A.3 of the permit, within 30 days of Division notification. B. Approval Expiration Division approval of a Qualifying Local Program will expire with this general permit on June 30, 2012. Any municipality desiring to continue Division approval of their program must reapply by March 31, 2012. The Division will determine if the program may continue as a approved Qualifying Local Program. VIII. TERMS AND CONDITIONS OF PERMIT A. Coverage under a QuaH(ying Local Program -For Small Construction Sites Onlv For small construction sites (disturbing less than 5 acres) covered under a Qualifying Local Program (see Section VIL above), only certain permit requirements apply, as outlined below. The local program must have been formally designated by the Division to qualify. Most municipalities have some type of local program and may require permits and fees. However, simply having a program in place does not necessarily mean that it is a qualifying program and that a State permit is not required. The local municipality is responsible for notifying operators and/or owners that they are covered by a Qualifying Local Program. As of May 31, 2007, the only approved Qualifying Local Programs within the state are for Golden, Durango and Lakewood. An updated list of municipalities with Qualifying Local Programs, including contact information, is available on the Division's website at: htm:l/w11,ri-v. cdolze.state. co. us/ivq/P ermits Unit/storm l·vater!constniction. html. The Division reserves the right to require any construction owner or operator within the jurisdiction of a Qualifying Local Program covered under this permit to apply for and obtain coverage under the full requirements of this permit. 1. Permit Coverage: If a construction site is within the jurisdiction of a Qualifying Local Program, the owner or operator of the constntction activity is authorized to discharge stormwater associated with small construction activity under this general permit without the submittal of an application to the Division. The permittee also is not required to submit an inactivation notice or payment of an annual fee to the Division. PART II Permit -Page 34 Permit No. COR-030000 VIII. TERMS AND CONDITIONS OF PERMIT (cont.) 2. Permit Terms and Conditions: The permittee covered by a Qualifying Local Program must comply with the requirements of that Qualifying Local Program. In addition, the following permit sections are applicable: a) Parts I.A.I, I.A.2, and l.A.3: Authorization to discharge and discussion of coverage under the permit. b) Part ID. I: General limitations that must be met in addition to local requirements. c) Parts I.D.2, I.D.3, I.D.4: BlvfP implementation, prohibition of non-stormwater discharges unless addressed in a separate CDPS permit, and requirements related to releases of reportable quantities. d) Part I.D.11: Potential coverage under a Total Maximum Daily Load (TMDL). e) Part 1.E: Additional definitions. j) Part II (except for Parts ILA.1, 11.B.3, 11.B.8, and 11.B.10): Specifically includes, but is not limited to, provisions applicable in the case of noncompliance with permit requirements, and requirements to provide information and access. B. Stormwater Management Plans (SWMPs) Prior to commencement of construction, a stormwater management plan (SWMP) shall be developed and implemented for each facility covered by this permit. A certification that the SWMP is complete must be submitted with the permit application. The SWMP shall identify potential sources of pollution (including sediment) which may reasonably be expected to affect the quality of stormwater discharges associated with construction activity from the facility. In addition, the plan shall describe the Best Management Practices (BMPs) which will be used to reduce the pollutants in stormwater discharges from the construction site. (Note that permanent stormwater controls, such as ponds, that are used as temporary construction BMPs must be adequately covered in the SWMP.) Facilities must implement the provisions of their SWMP as a condition of this permit. The SWMP shall include the following items: I. Site Description 2. Site Map 3. Stormwater Management Controls 4. Long-term Stormwater Management 5. Inspection and Maintenance (See Parts J.B. and I. C of the permit for a more detailed description of SWMP requirements.) The Division has a guidance document available on preparing a SWMP. The document is included as Appendix A of the permit application, and is available on the Division's website at •vwvv.cdphe.state.co.us/wq/PermitsUnit. Some changes have been made to the SWMP requirements. See Section II.I of the rationale for a discussion on permittee responsibilities regarding those changes. / VIII. TERMS AND CONDITIONS OF PERMIT (cont.) MasterSWMP PART II Permit -Page 35 Permit No. COR-030000 Often, a large construction project will involve multiple smaller construction sites that are within a common plan of development, or multiple well pads under construction within an oil and gas well field. Pollutant sources and the 'types of BMPs used can be relatively consistent in such cases. A permittee could significantly streamline the SWMP development process through the use of a master SWMP. SWMP information must be developed and maintained for all construction activities that exceed one acre (or _are part of a common plan of development exceeding one acre) conducted within the permitted area. By developing a single master plan, the permittee can eliminate the need to develop repetitive information in separate plans. Such a plan could include two sections, one containing a reference section with information applicable to all sites (e.g., installation details and maintenance requirements for many standard BMPs, such as silt fence and erosion blankets), and the second containing all of the lnformation specific to each site (e.g., site BMP map, drainage plans, details for BMPs requiring site specific design, such as retention ponds). As new activities begin, information required in the SWMP is added to the plan, and as areas become finally stabilized, the related information is removed. Records of information related to areas that have been finally stabilized that are removed from the active plan must be maintained for a period of at I east three years from the date that the associated site is finally stabilized. C. Total Maximum Dailv Load CTMDL) If the designated use of a stream or water body has been impaired by the presence of a pollutant(s), development of a Total Maxirnum Daily Load (TMDL) may be required. A TMDL is an estimate of allowable loading in the waierbody for the pollutant in question. Types of discharges that are or have the potential to be a significant source of the pollutant are also identified. If a TMDL has been approved for any waterbody into which the permittee discharges, and stormwater discharges associated with construction activiry have been assigned a pollutant-specific Wasteload Allocation (WLA) under the TMDL, the Division will either: 1. Notify the permittee of the TMDL, and amend the permittee's certification to add specific BMPs and/or other requirements, as appropriate; or 2. Ensure that the TMDL is being implemented properly through alternative local requirements, such as by a municipal stormwater permit. (The only current example of this is the Cherry Creek Reservoir Control Regulation (72.0), which mandates that municipalities within the basin require specific BMPs for constniction sites.) See Part I.D.11 of the permit for further information. D. Monitoring Sampling and testing of stormwater for specific parameters is not required on a routine basis under this permit. However, the Division reserves the right to require sampling and testing on a case-by-case basis, in the event that there is reason to suspect that compliance with the SWMP is a problem, or to measure the effectiveness of the BMPs in removing pollutants in the ejjluent. See Part I.D.l (e) of the permit. E. Facilitv Inspections Construction sites typically must inspect their stormwater management controls at least every 14 days and within 24 hours after the end of any precipitation or snowmelt event that causes suiface erosion. At sites or portions of sites where ground-disturbing construction has been completed but a vegetative cover has not been established, these inspections must occur at least once per month. (At sites where persistent snow cover conditions exist, inspections are not required during the period that melting conditions do not exist. These PART II Permit -Page 36 Permit No. COR-030000 VIII. TERMS AND CONDITIONS OF PERMIT (cont.) .. \ ~ -. conditions are on~v expected to occur at high elevations within the Colorado mountains.) For all of these inspections, records must be kept on file. Exceptions to the inspection requirements are detailed in Part LD.6 of the permit. F. SWMP Revisions The permittee shall amend the SWMP whenever there is a change in design, construction, operation, or maintenance of the site, which would require the implementation of new or revised BMPs. The SWMP shall also be amended if it proves to be ineffective in achieving the general objectives of controlling pollutants in stormwater discharges associated with construction activity. The timing for completion of SWMP changes is · detailed in Parts LD.5(c) and LD.5(d) of the permit. SWMP revisions shall be made prior to change in the field, or in accordance with Part I.D.5(d) of the permit. G. Reporting The inspection record shall be made available to the Division upon request. Regular submittal of an annual report is not required in this permit. See Part 1.D.9 of the permit. H. Annual Fee The permittee is required to submit payment of an annual fee as set forth in the Water Quality Control Act. Permittees will be billed for the initial permit fee within a few weeks of permit issuance and then annually, based on a July 1 through June 30 billing cycle. I. Responsibilitv for Permit The permit certification for a site may be inactivated, once coverage is no longer needed. The certification may be transferred, if another party is assuming responsibility for the entire area covered by the certification. In addition, permit responsibility for part of the area covered by the certification may be reassigned to another party. These actions are summarized below. The Stormwater Program construction fact sheet explains these actions in farther detail under the section on Multiple Owner/Developer Sites, and is available on the Division website at htm://\.vii·w.cdvhe.state.co.usAvq/PermitsUnit!stomrwater!ConstFactSheet.PDF, Section F. 1. Inactivation Notice: When a site has been finally stabilized in accordance with the SWMP, the permittee shall submit an Inactivation Notice that is signed in accordance with Part I.F. l of the permit. A summary of the Inactivation Notice content is described in Part I.A. 6 of the permit. A copy of the Inactivation Notice form will be mailed to the permittee along with the permit certification. Additional copies are available from the Division. For sites where all areas have been removed from permit coverage, the permittee may submit an inactivation notice and terminate permit coverage. In such cases the permittee would no longer have any land covered under their permit certification, and therefore there would be no areas remaining to finally stabilize. Areas may be removed from permit coverage by: -reassignment of permit coverage (Part I.A.8 of the permit); -sale to homeowner(s) (Part I.A.9 of the permit); or -amendment by the permittee, in accordance with Division guidance for areas where permit coverage has been obtained by a new operator or returned to agricultural use. PART II Permit -Page 37 Permit No. COR-030000 VIII. TERMS AND CONDITIONS OF PERMIT (cont.) 2. Transfer of Permit: When responsibility for stormwater discharges for an entire constntction site changes from one individual to another, the permit shall be transferred in accordance with Part LA. 7 of the permit. The permittee shall submit a completed Notice of Transfer form, which is available from the Division, and at rVW11-'. cdphe.state. co. us!wq!P ermits Unit. If the new responsible party will not complete the transfer form, the permit may be inactivated if the permittee has no legal responsibility, through ownership or contract, for the constnlction activities at the site. Jn this case, the new owner or operator would be required to obtain permit coverage separately. 3. Reassignment of Permit: When a permittee no longer has control of a specific portion of a permitted site, and wishes to transfer coverage of that portion of the site to a second party, the permittee shall submit a completed Notice of Reassignment of Permit Coverage form, which is available from the Division, and at www.cdvhe.state.co.uslwq/PermitsUnit. The form requires that both the existing permittee and new permittee complete their respective sections. See Part I.A.8 of the permit. J. Duration of Permit The general permit will expire on June 30, 2012. The pennittee's authority to discharge under this pennit is approved until the expiration date of the general permit. Any permittee desiring continued coverage under the general permit past the expiration date must apply for recertification under the general permit at least 90 days prior to its expiration date. IX.

Environmental Protection Agency (USEPA) National Pollutant Discharge Elimination System (NPDES) storm water regulations. This SWMP addresses construction activities associated with development of the natural gas resources in the Piceance· Basin Drilling area. This SWMP is intended to be periodically updated as needed to address planned developments, new disturbances, and other changes needed to manage stonn water and protect surface water quality. 1.1 Storm Water Runoff Permitting Requirements The Federal Clean Water Act [Section 402(p)) requires that discharges of pollutants to waters of the United States from any point source be regulated by NPDES permits. In November 1990 the USEP A published final regulations that established application requirements for storm water associated with construction activity for soil disturbances of 5 acres or more be regulated as an industrial activity and covered by an NPDES permit. In December 1999 the USEP A published final Phase II · NPDES regulations that established application requirements for storm water associated with construction activity for soil disturbances to be regulated as an industrial activity and covered by an NPDES permit. These regulations became effective July 1, 2002. On June 30, 2005, Colorado storm water regulations went into effect to require Colorado Discharge Permit System (CPDS) permits for storm water discharges from construction activities for small (I to 5 acre disturbance) oil and gas activities. Federal permit coverage for these discharges was conditionally exempted from the Federal Clean Water Act by the 2005 Federal Energy Bill. On February l, 2006, the CDPHE issued a letter clarifying that the CDPHE Water Quality Control Commission decided to maintain the existing requirements for stonn water permitting for oil and gas construction sites of 1 to 5 acres. 1.2 Project Description and Background The Piceance Basin wells will be located within Sections 1, 2, 8, 11, 12, 14, 15, & 18 of Township 8 South, Range 96 West of Garfield and Mesa Counties in Colorado. The town of Parachute, Colorado is the nearest population center. The Piceance Basin Drilling Program will be located approximately 5 miles south of Parachute. The current drilling and development plan includes pad construction, access road improvement/construction, pit construction, installation of associated facilities, well drilling, well completion, well 3 PICEANCE BASIN SWMP NOBLE ENERGY , INC. testing and pipeline constru.ction. The area of disturbance including the natural gas well pads, the access roads and gathering system pipeline will be greater than five acres. 1.3 Project Owner and Operator The lease owner and operator is Noble Energy, Inc. Their address is: Noble Energy, Inc. 804 Grand A venue Platteville, Colorado 80651 Ph (970) 785-5000 The Noble local contact person for the project is Randy Raines. Mr . Raines can be contacted by phone at (970) 309-4968. Noble will be in charge of all aspects of this project. Contractor(s) will do the actual construction but all work will be supervised by Noble and all decisions will be made by Noble. 4 PICEANCE BASIN SW1vfP NOBLE ENERGY, INC. 2.0 CONSTRUCTION SITE DESCRIPTION 2.1 Site Location and Construction Area Description The Piceance Basin wells will be located within Sections 1, 2, 8, 11) 12, 14, 15 , & 18 of Township 8 South,-Range 96 West of Garfield and Mesa Counties in Colorado. The town of Parachu.te, Colorado is the nearest population center . The Piceance Basin wells will be constructed using conventional cut and fill earthmoving techniques . Typically, the working pad surface will have dimension of approximately 200 feet by 400 feet. Each pad will have a reserve pit that is approximately 60 feet by 250 feet. Specific pad dimensions vary depending on the planned drill rig, number of wells to be drilled from each pad, and local conditions. The drilling reserve pit will be used during drilling to hold drilling fluids and cuttings. The reserve pits will be designed , constructed, and reclaimed according to Colorado Oil and Gas Conservation Commission (COGCC) requirements . In areas that are disturbed by well construction, topsoil will be stripped and stockpiled near the site. Soil materials will be managed so that erosion and sediment transport are minimized. Nearby drainages will be protected by appropriate measures. The well pad will be graded to drain the pad surface to the reserve pit and to direct runoff from SUITounding areas away from the well pad and reserve pit. 2.1 Schedule of Construction Activities Natural gas exploration, development, and production activities are currently underway within the Piceance Basin drilling program . Existing and future well pad s and facilitie s are included in this SWMP . The development of natural ga s well s is generally accomplished in three distinct work phases. The first phase is the Development (Construction/Drilling/Completion), the second phase is the Production (Operation/Maintenance), and the third phase is the Abandonment and Final Reclamation. Each work phase is briefly discussed below . Developme11t (Co11structio11/Drilli1tg!Completion/R.eclamatio1t) Approximately % of an acre of surface terrain is disturbed during the construction of a new pad. The Development phase includes the following activities; pad construction, well drilling, well completion, gas line installation, and pad area reclamation. Pad reclamation is accomplishe4 by backfilling the reserve pit, contouring di sturbed soils to conform with the surrounding terrain, replacing the stockpiled top soil, seeding of disturbed soil areas in order to reestablish a cover vegetation, and construction of erosion and sediment control structures. The completion of a well (gas production) generally triggers a one -year time period in which the reclamation phase of work should be completed. For the specific fmal stabilization seed mixture please refer to the Figure 2. 5 PICEANCE BASIN SWMP NOBLE ENERGY, INC. Production (Operation/Maintenance) The production phase includes the operation and maintenance activities during natural gas production. The typical equipment on a pad during the production phase consists of a wellhe~d, a separation unit, from one to several 300-barrel capacity aboveground tan.ks f9,tCo~densate, and ~I!~l?Qve ground tank for storing produced water. Gas pipelines are also installed during this phase of work. ,, Reclamation activities during this phase include maintenance of revegetated areas and maintenance of the erosion and sediment control structur~s. Natural gas wells in the Piceance Basin area are projected to produce for approximately 20 to 30 years. Abandonment and Final Reclamation When the natural gas production of a well is exhausted it will be abandoned. Upon well abandonment each borehole will be plugged, capped, and all surface equipment will be removed . Subsurface pipelines will be removed to specified locations and plugged. The pad area will be reclaimed by contouring disturbed soils to conform to the surrounding terrain, by replacing tf1:e stockpiled top soil, by seeding of disturbed soil areas in order to reestablish cover vegetation, and by construction of erosion and sediment contrql structures as needed. Once· stabilization is achieved, defined as uniform vegetative cover established with a density of at least 70 percent of pre-disturbance levels, a well pad may be removed from this SWMP for sediment control~. However, if petroleum hydrocarbons or other chemicals impact stonnwater as a result of industrial activities onsite, the impacted stormwater will be addressed by following a spill prevention control and countermeasures (SPCC) plan. 2.2 Runoff Characteristics Runoff characteristics are based on site topography, soil type, and soil /vegetative cover. The upper part of the Parachute soil series is classified as a Bucklon-Incbau-Cochetopa soils series consists of shallow to deep, well drained, moderately sloping to steep soils on mountains and alluvia's. The lower part of the Parachute soil series is classified as a Potts-Ildefonso-Vale: this soil series consists of well drained, gently sloping to steep soils on mesas, alluvial fans, terrac~s and benches. These soil types are typical betWeen 5000- 7000 feet in elevation. The native vegetation is mainly pinyon, juniper, sagebrush, shadescale saltbush, greasewood, yucca, and Indian ricegrass. The permeability of the Bucklon-Inchau-Cochetopa soils is 0.06 to 2.0 inches per hour. The available water capacity is 0 .16 to 0 .18 inches per inch; for the Potts series the available water capacity is 0.6 to 6 inches per hour, and the water capacity is 0.08 to 0.20 inches per inch. The runoff coefficient will range from 0.10 to 0.30 . The pre-disturbance 6 PICEANCE BASIN SWMP NOBLE ENERGY , INC. percent ground cover ranges. from 80 to 98 percent .For specific pad percent ground cover information please refer to the plat maps. Possible receiving waters include unnamed tributaries of Wallace Creek, Spring Creek, Bill and Pete Creek, Little Alkali Creek, and the Colorado River. 7 PICEANCE BASIN S WMP NOBLE ENERGY, INC. 3.0 POTENTIAL POLLUTION SOURCES Potential pollution sources associated with construction sites and natural gas development include: • Sediment resulting from erosion of soil stockpiles and other areas cleared of vegetation; • Leakage of fuels and lubricants from equipment and spills from fueling; • Trash and debris from clearing activities, constrnction materials, and workers; • Leakage or spills from storage tanks and process equipment associated with the natural gas development activities. The most common source of pollution from pad and access road construction is sediment, which can be carried away from the work site with storm water runoff and impact the water quality of a receiving stream. Clearing, grading, and otherwise altering previously undisturbed land can increase the rate of soil erosion over pre~disturbance rates. Petroleum products can also be potential storm water pollutants. These products are used in construction activities to power or lubricate equipment and include: fuel, gear oil, hydraulic oil, brake fluid, and grease. Debris from laydown areas, residue from equipment cleaning and maintenance, and solid waste generated from land clearing operations and hurrian activity (trees, brush, paper, trash, etc.) present other potential pollution sources within the construction site. Spills or leaks from potential sources are described in the SPCC plan. Response to certain events may require specialized training due to health and safety concerns. 8 PICEANCE BASIN SWMP NOBLE ENERGY, INC. 4.0 DESCRIPTION OF CONTROL MEASURES 4.1 Soil Erosion and Sediment Controls The objective of erosion and sediment controls is to minimize the release of sediments to stonn water runoff. This can be accomplished through the use of structural and/or nonstructural controls. This section describes erosion and sediment controls to be used at active construction sites to minimize possible sediment impacts to storm water runoff. The proposed erosion control features can include: • Placement of any topsoil stockpiles along the cut-slope side of the pad to divert run-on; • Installation of a diversion ditch at or below the toe of fill slopes where located within 100 feet of surface water drainages or where 'Steep slopes will likely result in rapid drainage from the location to nearby drainages, and; • Installation of check dams in areas of concentrated flow; • Installation of soil berms around the edges of the pad to prevent runoff over the sides of the pad; • Grading of pads to collect and drain water to the reserve pit. Uphill topsoil stockpile/diversion berm & ditches In order to divert surface runoff from upgradient areas away from the pad, salvaged topsoil may be placed on the uphill side of the cut slope. The topsoil stockpile may be placed and graded into a berm to direct flow toward sediment control structures. The construction of a diversion ditch in front of the berm will prevent runoff unto the pad. Downhill silt fence The silt fence is a temporary structure that is designed to slow, temporary impound, and filter sediment laden water. Installation techniques and maintenance is critical to proper performance. Silt fences will be installed at the down gradient edge of the fill slopes located within l 00 feet of a surface drainage. Typical silt fence installation details are given in Appendix B. 9 I I I I PICEANCE BASIN SWMP NOBLE ENERGY, INC. Hay bale check dams Hay bale dams are temporary structures of rectangular hay bales tightly butted together and staked into the ground. The hay bales help impound the water and settle out the heavier~ 9 9 ~s~ s~diments. H~y Qfll~ ~heck dams, at a minimum wilt be.installed in areas of concentrated flow . Typical hay bale check dam installation details are given in Appendix.B . Rock check dams Rock check dams will be installed in areas of concentrated flow. Rock check dams. may be used instead of hay bale check dams in areas where steep slopes, high flows , or long- term exposure are expected to result in failure or frequent maintenance of a hay bale structure . Road drainage relief Culverts, rolling dips or water bars may be used to provide drainage of water from road surfaces as needed to drain low areas or to reduce the amount of water flowing on the road surface . Road drainage relief should be provided as needed and in accordance with generally accepted practices. Guidance for road drainage relief is available in the doctunent "Low-Volume Roads Engineering, Best Management Practices Field Guide," developed by the U.S. Forest Service and available on-line at http://www.blm.gov/bmp/field%20guide.htm. Depending on the location and type of draina.ge relief installed, additional sediment control features may be needed such as sediment removal at the inlet and erosion protection at the outlet. Culvert inlet and outlet protection Installation of culverts may be needed in certain areas where the access road intersects inte!mittent drainages. The culvert inlet area will include a sediment sump. The culvert outlet area will also include an energy dissipation feature . The area of rock lining should be prepared by removing 6-to 8-inches of soil . The shallow excav ation should be filled with rock and the rock secured in-place by bucket tamping or wheel-rolling. The rock outlet should be installed to promote lateral spreading of water as it flows acro ss the rock. 10 PICEANCE BASIN SWMP NOBLE ENERGY, INC. Soil berms Soil berms may be used to divert drainage away from areas of concern or to direct flow toward sediment control structures. Where used, soil benns shall be constructed of soil with sufficient fines to minimize flow through the berm. Berms shall be at least 18 • inches tall and will be compacted in place by wheel rolling with suitable rubber tired, heavy eql,lipment. Straw waddles/straw rolls Straw rolls are intended to capture and keep sediment on the slopes. Straw rolls are useful to temporarily stabilize slopes by reducing soil creep and sheet and rill erosion until permanent vegetation can be established. Straw rolls will last an average of one to two years. The slope needs to be prepared before the rolls are placed. Small trenches are created across the slope on the contour. The trench should be deep enough to accommodate half the thickness of the roll (about 3"·5''). The trenches need to be 10 to 25 feet apart. The rolls need to be installed perpendicular to water movement, parallel to the slope contour. Start by insta lling rolls from the bottom of the slope. The rolls need to fit snugly against the soil. No gaps should be between the soil and roll. Willow or wooden stakes need to be driven through the roll and soil. There should only be l to 2 inches of stake exposed above the roll. The stakes should be installed every 4 feet. Natural vegetative cover An effective way to prevent erosion and sedimentation is to preserve the existing vegetation. It can provide both dust control and a reduction in erosion potential by increasing infiltration, trapping sediment, stabilizing the soil, and dissipating the energy of hard rain. Natural vegetative cover can be applied to any site and is not restricted by the type of soil, topography or climate. Sediment collection basins Sediment collection basins are intended to intercept, trap, and retain sediment from runoff while allowing detained runoff to slowly drain, infiltrate, or both. This structure is used for indefinite periods of sediment collection associated with disturbance. The basin is constructed by excavation, embankment, or a combination of the two. The embankment is usually constructed with compact earth with straw bales on top to act as further filtration for overflow. The size of the basin should be able to accommodate the mnoff of the area. The basins usually require removal of collected sediment to restore adequate operating capacity. 11 PICEANCE BASIN SWMP NOBLE ENERGY, INC. Pipe or armored rundowns Rundowns are for those situations requiring runoff to be conveyed from the top slope to the bottom to avoid damage to disturbed areas, especially on steep slopes . The pipe rundowns consist of a pipe that conveys the storm water from the top of a pad to the sediment collection basin on the bottom . The armored rundown can consist of rip rap and blankets placed in a channel along the side of a pad to convey storm water from the top of a pad to th!! sediment collection basin below. Seeding of disturbed areas Project areas disturbed by construction will be revegetated as soon as practi.~able following construction. Areas that will be revegetated will primarily be cut and fill slopes associated with grading activities. The permanent mix, rate, application method, and supplemental materials will b.e selected by the revegetation contractor. 1t is anticipated that this will include suitable grass species supplemented by cereal crops. Rocky areas In areas of the project, the depth to bedrock ·is expected to be relatively shallow . Excavation in these areas will result in rock fragment and pieces being exposed on the ground surface. Rock pieces, typically sedimentary sandstone, siltstone or shale, will provide a surface that is erosion resistant. Both cut and fill slopes in rocky areas may result in a surface that is similar to gravel surfacing (see below) and depending on the extent of rock pieces may preclude the use of downstream sediment retention BMPs (such as berms or silt fence). The person selecting BMPs should use experience and good judgment in determining which rocky soils will or won't require downstream BMPs . Gravel surfacing Gravel surfacing may be used to cover soil in areas of high traffic such as roads, facility areas, and the area near well heads. Gravel surfacing forms a layer that protects soil from wind and water erosion and prevents vehicle tracking. 12 PICEA.t"\ICE BASIN SWMP NOBLE ENERGY, INC. Additional BMP references The structural and non-structural BMPs listed above are intended to include all BMPs that may be used for gas gathering projects. However, there may be situations where a BMP is needed but not included above or project personnel may need additional information on the use, specifl_catiQ!l, and rrui.int~nance of BMPs. Additional information resources are listed beiow: • For oil and gas operations, the Bureau of Land Management and U.S. Forest Service have developed "Surface Operating Standards and Guidelines for Oil and Gas Exploration and Development," "Gold Book." The most recent version (fourth edition) of this is available on the internet at http://www.blm.gov/bmp/GoldBook Draft v12.pdf. • For construction BMPs the Urban Drainage and Flood Control Distr~ct, a Colorado front range group of city and county agencies has developed a BMP manual that is available on the internet at http://www.udfcd.org/usdcrn/vol3.htm • For construction BMPs and surface stabilization methods, the Alabama Soil and Water Conservation Committee has developed "Erosion Control, Sediment Control and Stormwater Management on Construction Sites and Urban Areas, Volume 1 Developing Plans and Designing Best Management Practices." This information is available on the internet at http://swcc.state.al.us/pdf/ASWCC June 2003 Alabama Handbook Constructio n E&S Control.pdf • For access roads, the US Forest Service and Bureau of Land Management have developed "Low-Volume Roads Engineering, Best Management Practices Field Guide," which is available on the internet at http://www.blm.gov/bmp/field%20guide.htm 13 PICEANCE BASIN SWMP NOBLE ENERGY, INC . 4.2 Storm Water Management Controls Structural BMPs will be installed, inspected, and maintained as needed. This SWMP will b e revised as needed to address new disturbances. DeQ~!!4ing on th~ typ~ ~d locath:m of new facilities tnere-may be a need for.i nclusion of new and different BMPs . In general , new devy_lopment should be planned with consideration for stonn water quality (e.g. minimize disturbed area and maximize distance from surface water drainages , as practicable). Other developments on the property, primarily existing and/or improved roads, not currently or specifically addressed in the SWMP will be periodically checked for erosion and drainage problems. This is especially important for access roads located within 100 feet of surface drainages or creeks. If problems are noted, they should be reported to the Site Manager and/or SWMP administrator. Problem areas may be addressed tlu·ough construction activities , but will likely need to be addressed through BMPs which will be added to the plan as needed. 14 PICEANCE BASIN SWMP NOBLE ENERGY, INC. 4.3 Other Controls 4.3.1 Waste management and disposal Pad and access road construction will generate various other wastes during the course of construction . Other wastes may include the following: • Trees and shrubs from clearing operations, • Trash and debris from construction materials and workers, • Sanitary sewage . Each of these wastes will be managed so as to not contribute to storm water pollution. Trees and shrubs will be piled along the toe of fill slopes to provide additional sediment control. Construction trash and debds will be collected in containers and hauled off~site for disposal in suitable landfills. Sanitary waste will be containeri zed in portable toilets or other storage tanks with waste materials regularly pumped and transported off-site for disposal at approved facilities . 4.3.2 Fuels and materials management Petroleum Products Petroleum products which may be pre sent at the construction site include : gasoline, diesel fuel, lubricant oils, hydraulic oils, used oils, and solvents. Gasoline and diesel fuel will be stored in portable storage tanks with secondary containment. Lubricant , hydraulic, and miscellaneous oils and solvents will be stored in 55-gailon or smaller containers . Pollutants from petroleum products used during construction activities adhere easily to soil particles and other surfaces. In case of a spill or leak, soils contaminated with petroleum productS will be contained and removed to a proper disposal site. Proposed soil erosion and sediment control practices will aid in retention of spills or leaks. Use of secondary containment and drip pans will reduce the likelihood of spills or leaks contacting the ground . Proposed maintenance and safe storage practices will reduce the chance of petroleum products contaminating the road site. Oily wastes such as crankcase oil, cans, rags , and paper containing oils will be placed in proper receptacles and di sposed of or recycled. An additional source of petroleum contamination is leaks from equipment and vehicles. Routine daily inspections will be conducted to identify leaks and initiate corrective actions, if needed . The following guidelines for storing petroleum products will be used . • All product containers will be clearly labeled. • Drums will be kept off the ground within secondary contairunent and stored under cover if needed. 15 PICEANCE BASIN SWMP NOBLE ENERGY, INC. • Fuel tanks will be s~ored within secondary containment. • Lids of drummed materials will be securely fastened. • Emergency spill response procedures will be available on-site. Persons trained in handling spills will be on call at all times. • Spill clean up and containment materials (absorbent, shovels, etc.) will be easily accessible. Spills will be immediately cleaned up and contaminated materials will be properly stored on site until they can be disposed of in accordance with applicable regulations. • Storage areas and containers will be regularly monitored for leaks and repaired or replaced as necessary . Workers should be reminded about proper storage and handling of materials dming \.veekly subcontractor or safety meetings Other Chemicals Products Management Additional materials will be used and stored on site for use in construction. These materials will be stored appropriately and managed to minimize spills and leaks. Storage areas will be regularly inspected and any minor spills or leaks will be cleaned up immediately. Materials Management The construction contractor will maintain a laydown or staging area for equipment and materials storage on site. These areas will be maintained with good housekeeping and will be inspected on a regular basis for spills, leaks, and potential contamination. 4.3.3 Construction Site Housekeeping Housekeeping will consist of neat and orderly storage of materials and containerized fluids . Wastes will be temporarily stored in sealed containers and regularly collected and disposed of at off-site, suitable facilities . If spills occur prompt cleanup is required to minimize any commingling of waste materials with stonn water runoff. Routine maintenance will be limited to fueling and lubrication of equipment. Drip pans will be used dtu"ing routine fueling and maintenance to contain spills or leaks . Any waste product from maintenance will be containerized and transported off site for disposal or recycling. There will be no major equipment overhauls conducted on site. Equipment will be transported off site for major overhauls. Cleanup of trash and discarded materials will be conducted at the end of each work day. Cleanup will consist of patrolling the road way, access areas, and other work areas to pickup trash, scrap debris, other discarded materials, and any contaminated soil. These materials will be disposed of appropriately. 16 PICEANCE BASIN SW11P NOBLE ENERGY, INC. 5.0 INSPECTION AND MAINTENANCE PROCEDURES To meet requirements . of the General Pennit inspection and maintenance of erosion and sediment controls must occur during the project. Continued inspection and maintenance is required for specific structures after construction is completed. The inspection program will include the following: 1. A qualified person familiar with the SWMP and control measures will conduct the inspections. 2. Inspections will cover these area of the construction site: • Disturbed areas without stabilization, • Material storage areas, • Best Management Practices (BMPs), • Surface water diversions, • Downgradient areas, • New access roads, and • Locations where vehicles enter or exit the site. 3. Inspections will occur at least once every 14 calendar days and afte r a significan t precipitation or snow melt event that causes erosion. 4. Completed and stabilized sites will be inspected at least once per month. 5. A log of inspections will be kept. 6. Water quality will be assessed for all receiving streams and discharge areas during each inspection. 7. Disturbed areas and material storage areas that are exposed to precipitation will be inspected for evidence of pollutants entering nearby drainages. 8. Check dams, silt fences, and other BMJ>s will be inspected for evidence of deterioration, under-cutting, and build up of sediment. Sediment will be removed when it has built up one-third to one-half the height of the bay bales or silt fence. 9. Roads used for vehicle access will be inspected for evidence of off-site sediment transport. l 0. Following each inspection, the SWMP will be modified as neces sary to include additional controls designed to correct identified problems. Revisions to the SWi'vfP will be made within 7 days of the inspection. 11. An inspection report summarizing the scope of the in spection, the name of the person conducting the inspection, date of inspection, and observatipns relating to the implementation will be prepared. Inspection reports will be ret ained for at least 3 years from the date that the site is finally stabilized . 12. Actions taken to modify any sto1m water control measure will be recorded and maintained with the SWlv1P. 13 . If no deficiencies are found during the inspection, the rep ort will contain certification that the site is in compliance with the SWMP. Signatures will be in accordance with the General Permit Conditions, Part E. I (Appendix A): 17 PICEANCE BASIN SWMP NOBLE ENERGY, INC . Maintenance will include prompt repairs and/or adjustments to any erosion and sediment control structures that are deteriorating or found to be performing inadequately. Repairs should be made as soon as possible and prior to the next anticipated storm event. Noble Energy, Inc. or designated contractor(s) will maintain, on-site all materials necessary to make any reasonably expected repairs such as silt fence, hay bales, and stakes. 18 PICEANCE BASIN SWMP NOBLE ENERGY, INC . 6.0 NON-STORMWATER DISCHARGES No non-stonn water discharges are anticipated from the project. Possible exceptions include fire prevention/suppression or dust control activities. 19 PICEANCE BASIN SWMP NOBLE ENERGY, INC . 7 .0 FINAL STABILIZATION Areas which have been disturbed are considered to be stabilized when a uniform vegetative cover with a density of 70 percent of the pre-disturbance levels has been established or when an equivalent permanent-, physical erosion reduction -method is in- place. For the specific final stabilization seed mix please refer to Figure 2. Areas at which are not used for facilities , access roads, materials storage yards, or other work areas will be stabilized with vegetation. Areas that are stabilized with vegetation will be considered to have achieved final stabilization when a uniform stand of vegetation with a density of at least 70 percent of the pre-disturbance has been established. Other areas which may include facilities, access roads, materials storage yards, and other work areas will be stabilized with the use of permanent, physical erosion reduction methods which include, but are not limited to: 1. Surface hardening -covering of the soil surface with hardened products such as concrete or asphalt pavement. 2. Surface covering -covering of the surface soil with structure that inhibits contact of precipitation with the soil surface which is generally considered -to be placement of a structure (building or tank) over the soil surface. 3. Gravel surfacing -gravel surfacing will be applied in areas such as access roads, materials storage yards, and other work surfaces. Some gravel may be lost due to erosion from intense precipitation events or due to vehicle traffic . Gravel surfaces will be periodically inspected to determine the need for gravel replacement. Gravel surfaces will be replaced or repaired (through grading) when inspection reveals that the gravel surface is no longer effectively covering the soil surface. 20 l I I I I I I I l I ! l PICEANCE BASIN SW11P NOBLE ENERGY, INC. 8.0 CERTIFICATIONS 8.1 Owner/.Applicant Certification I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.

Ramos Laydown Yard OA Project No. 013-2329-100 Reclamation Plan Noble Energy Inc. Noble estimates that the proposed laydown yard will be in operation for an anticipated period of approximately thirty (30) years in order to accommodate Noble’s natural gas operations. Upon termination of the development and production activities, the communication tower location will be reclaimed, as outlined below:  All equipment and structures will be removed.  Noble will remove all safety and stormwater BMPs, and other surface objects from the premises.  Noble will restore the site to pre-facility conditions by re-contouring and re-vegetating the site. Top soil will be redistributed across the site and will be reseeded with an approved seed mix (see attached seed mix recommendation).  Noble will monitor the site to ensure that 70 percent of the pre-existing vegetation is achieved. Seedbed Preparation and Slope Reconstruction: Cut and fill slopes will be backfilled and re-contoured to a slope of 3:1 – 2.5:1 or less in instances where necessary to match the existing natural contours. Following final contouring, all backfilled or ripped surfaces will be covered evenly with topsoil. Re-contouring should form a complex slope with heavy pocking. In areas with slope greater than 3 percent, imprinting of the seed bed is recommended. Final seedbed prep will consist of scarifying/imprinting the topsoil prior to seeding. Imprinting can be in the form of dozer tracks or furrows perpendicular to the direction of slope. When hydro-seeding or mulching, imprinting should be done prior to seeding, unless the mulch is to be crimped into the soil surface. If broadcast seeding and harrowing, imprinting will be done as part of the harrowing. Furrowing can be done by several methods, the most simple of which is to drill seed perpendicular to the direction of slope in a prepared bed. Other simple imprinting methods include deep hand raking and harrowing, always perpendicular to the direction of slope. All compacted areas will be ripped to depth of 18” with max furrow spacing of 2’. W here practicable, ripping will be conducted in two passes at perpendicular direction. Topsoil: Following final contouring, all backfilled or ripped surfaces will be covered evenly with topsoil. The topsoil in the cut slope on the back of the pad will be heavily pocked using the excavator bucket to form an uneven soil surface complex which will aid in revegetation and help with slope stabilization. The fill slope, and remaining disturbed, and reclaimed areas will be track walked to aid in revegetation and slope stabilization. In areas that may not have been disturbed during the reclamation process or areas of suspected compaction that will be reseeded, measures will be taken to loosen and spread the topsoil. These measures may include scarifying the soil by racking or harrowing the soil. Seed Mix: Seed mix used for reclamation will be taken from the approved seed mixtures identified below: Noble Energy, Inc.

Double this rate (120 PLS per square foot) if broadcast or hydroseeded. Seeding Procedures: For best results and success, the recommended grass mixture reseeding should be done in late autumn in order to take advantage of natural precipitation for the region. The reseeding rate should be doubled for broadcast application. Preferred seeding method is multiple seed bin rangeland drill with no soil preparation other than simple grading to slope and imprinting and water bars, where applicable. Alternative seeding methods include, but are not limited to:  harrow with just enough soil moisture to create a rough surface, broadcast seed and reharrow, preferably at a 90 degree angle to the first harrow;  hydro-seeding (most economical in terms of seed cost); and  hand raking and broadcast followed by re-raking at a 90 degree angle to the first raking.  These are not the only means of replanting the site. However, these methods have been observed to be effective in similar landscapes. The prepared soils will be seeded (weather permitting) no more than 24 hours following completion of final seedbed preparation. The seeding will be conducted by means of drilling the prescribed seed at prescribed seeding rate. The seed will be drilled with a common range drill at a depth of 0.25 – 0.5” beneath the soil surface. The seed will be drilled horizontally across the pad faces and perpendicular to the track walking when possible. When slope gradient less than 2.5:1 exists and drilling is not possible from a mechanical and safety standpoint the soils will be broadcast seeded at twice the prescribed amount. The reseeding will be monitored and reseeded as appropriate until the reclamation standards detailed above are met. Mulch: With 24 hours of reseeding (weather permitting) hydromulch will be applied to all reclaimed and reseeded surfaces. Areas where the erosion potential is such that biodegradable blankets will be used will not be hydromulched. Noble Energy, Inc. Reclamation Plan Page 4 This page left blank for two-sided printing.

The storage use would be limited to a 92,137 square foot or 2.11 acre area. Rural residential, natural gas development and agriculture are the uses on the subject parcel and surrounding properties. Natural gas development is the predominate use in the immediate area. The closest residential uses to the proposed storage yard are approximately 1500 feet to the west (Nauroth), 1,000 feet to the south (Murray) and 1,000 feet to the east (Ramos). The residential use to the east is on the subject parcel. The parcel to the north only contains oil and gas production facilities. 2. Site Features The subject property is located in the Rural (R) zone district of Garfield County in the Northeast ¼ of the Southwest ¼ of Section 1, Township 8 South, Range 96 West of the 6th PM. Access to the Storage Area is via Garfield County Road (CR) 300 (Stone Quarry Road) to CR306 (Wallace Creek Road) for approximately 2.4 miles and then north on a private access road. The access road to the site runs through a Noble Energy Inc. (Noble) natural gas well pad, the Ramos 1-36 Pad. The site is locate at approximately 5910 feet in elevation. All native vegetation has been removed from the project site and the area is currently being used as a laydown yard and storage facility. This pad contains an earthen berm around its perimeter and is surrounded by a fence with a gate controlled by Noble. This fence is intended to prevent vehicles, livestock, and wildlife from entering the laydown yard area. The vegetation types located outside of the fenced area consist of sagebrush steppe, mixed grasslands, and pinyon-juniper communities. 3. Soil Characteristics Soils, consisting of the following units, are within the study area around the proposed laydown yard: Potts loam (Unit 56): The Potts loam is a deep well-drained, moderately sloping to rolling soil found on mesas, benches, and the sides of valleys at elevations ranging from 5000 Noble Energy Inc. Ramos Laydown Yard Impact Analysis Page 2 feet to 7000 feet. The Potts loam formed in alluvium derived from sandstone, shale, or basalt. The permeability is moderate, and available water capacity is high. Surface runoff is medium, and the erosion hazard is severe. Potts-Ildefonso complex (Unit 58): The Potts-Ildefonso complex soils are strongly sloping to hilly soils formed on mesas, alluvial fans, and the sides of valleys with 12% to 25% slopes. The Potts soil formed in alluvium derived from sandstone, shale, or basalt and makes up 60 percent of this unit while the Ildefonso soil formed in calcareous, basaltic alluvium, and small amounts of eolian material and makes up about 30% of the unit. The Potts-Ildefonso soils are deep, well drained, permeability is moderate to moderately rapid, and the available water capacity is high. The surface runoff of these soils is medium, and the erosion hazard is moderate. 4. Geology and Hazard This is a summary of the Natural and Geologic Hazard Assessment Report that is provided with this application.  Geological hazards are not expected to be associated with the installation of buried utilities since the proposed laydown yard is not expected to have any buried utility lines.  Avalanche areas are present in the northeastern parts of Garfield County in parts of the Park Range and Flat Tops mountain range. Avalanche conditions are not expected to be present in area of the Site.  Rockfall areas are present in some areas of the steep canyons and narrow drainages incised by area streams, but are not expected to be a hazard in the vicinity of the Site.  Alluvial fan hazard areas are present along parts of the Colorado River drainage where tributary drainages from higher elevations have deposited sediments onto bedrock overlying the Wasatch Formation. These conditions are not present in the vicinity of the Ramos laydown yard.  The soil onsite has been mapped as the Potts Loam. Community development and recreation are limited for the Potts Loam by low-strength, shrink-swell potential, and slope. Considering the nature of the proposed development, the low-strength and shrinks/well potential of the soils are not expected to affect the laydown yard. Slope development may be an issue in the vicinity of the proposed laydown yard, since based on the descriptions of the soil type, slopes have been identified as moderately to severely limiting for development. Engineering controls will need to be taken into consideration with the proposed development. Therefore, slopes may be a hazard in the laydown yard area.  Corrosive or expansive soils and rock are not expected to be present in the vicinity of the proposed laydown yard site.  Collapsible soils are not present in the vicinity of the proposed laydown yard site.  No significant faulting is known in the laydown yard site. Noble Energy Inc. Ramos Laydown Yard Impact Analysis Page 3  No flood prone areas are mapped in the vicinity of the site. Flash flooding is an issue for lower elevations along Spring Creek, Wallace Creek, Pete and Bill Creek and areas along the Colorado River are prone to flood risks.  There are no mining activities shown in the vicinity of the site.  There are no naturally occurring radioactive mineral deposits known in the site area. NORM/TENORM may be an issue with exploration and production and could be an issue with used pipe scale. 5. Groundwater and Aquifer Recharge Areas No flood prone areas are mapped in the vicinity of the site. Flash flooding is an issue for lower elevations of Spring Creek, Pete and Bill Creek, and Wallace Creek areas along the Colorado River. An individual sewage disposal system (ISDS) is not being used at this site so soils will not have to support waste disposal. The site was previously graded. Minor soil disturbance and construction activity will be required to accommodate the grading and drainage plan. All soil disturbances have been fully stabilized according to CDPHE and COGCC criteria. 6. Environmental Impacts a. Determination of long-term and short-term effects on flora and fauna Flora It is not likely that the existing laydown yard would adversely affect federally listed plant species. No additional vegetation removal is associated with the laydown yard, since it is an existing storage facility and within an existing footprint. Vegetation communities and conditions will not be affected on a long or short term basis and will likely remain in their present condition. Fauna Federally Listed Threatened, Endangered, and Candidate Wildlife Species It is not likely that the existing laydown yard would adversely affect federally listed wildlife species. No additional vegetation removal is associated with the laydown yard, since it is an existing storage facility and within an existing footprint. No federally listed species or critical habitat occurs within or near the site. Raptors, Birds of Conservation Concern, Migratory and Non-Migratory birds No additional vegetation removal would be associated with the Ramos Laydown Yard; therefore no suitable raptor, birds of conservation concern, or other migratory or non- migratory bird species nesting habitat would be affected. Long- or short-term effects related to the site would be minimal due to the area being previously disturbed from activities associated with the laydown yard and the operation and maintenance of the nearby Ramos 1-36 pad. Noble Energy Inc. Ramos Laydown Yard Impact Analysis Page 4 American Elk and Deer Wildlife habitat is not present within the laydown yard. No additional vegetation removal will occur at the site. No impacts to deer or elk would occur as a result. Disturbance associated with human presence and some activities at the site may cause elk and deer to avoid this area; however, this area would remain the same as existing conditions. The Ramos Laydown Yard does not block or impede migration corridors for elk or mule deer. Black Bear and Mountain Lion No additional vegetation removal would occur as a result of this site; therefore, suitable habitat for black bear and mountain lion would remain the same as existing conditions. It is possible that human interactions could occur, but the mapped conflict areas were more than a mile northeast of the site. Small Mammals and Reptiles and Aquatic species No impacts are anticipated to occur to any small mammals or reptiles, since there will be no additional vegetation removal associated with the site. The laydown yard is absent of any vegetated habitat. Habitat is present directly adjacent to the site that would offer forage and resting opportunities for small animals. No aquatic species would be impacted by the Ramos Laydown Yard. b. Determination of the effect on designated environmental resources, including critical Wildlife Habitat The Ramos Laydown Yard is not expected to affect any critical habitat for any wildlife species, as no federally designated critical habitat or species were identified within or near the site. According to the CPW-NDIS GIS data, the laydown yard occurs within overall and winter range for elk and overall range, winter range, and winter concentration area for mule deer. No additional vegetation removal or construction is associated with the site that would further decrease habitat, but could preclude these species from using adjacent habitat as a result of increased human presence. This would not impede any natural migration or movement through the area. c. Impacts on wildlife and domestic animals through creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns, or other disruptions Impacts to wildlife or domestic animals are expected to be minimal through the creation of hazardous attractions. An existing fence surrounds the site and is used to protect the contents within the laydown yard and to potentially deter domestic animals or wildlife from entering the yard. Since the area is previously disturbed and lacking wildlife habitat, alteration of existing native vegetation has already occurred. The site is currently under a weed management plan implemented by the Noble Energy Inc. The site may disrupt the overall use of the area by wildlife, but due to the relatively small area compared to suitable adjacent habitat, it is not anticipated that the laydown Noble Energy Inc. Ramos Laydown Yard Impact Analysis Page 5 yard would permanently preclude wildlife movement. The inherent risks associated with the use of the laydown yard by birds and small mammals would likely be minimal due to absence of vegetation within the site. However, some bird species or small animals may inhabit or nest on or around equipment. The inherent risks are low. The potential risks can be reduced by closing cavities or covering openings. d. Evaluation of any potential radiation hazard that may have been identified by the State or County Health Departments Radon is not expected to be a significant problem at the proposed site since the development will not include any permanent structures, personnel will not be onsite for extended periods, and the site will not be developed with structures containing basements or substructures in which radon can accumulate. Colorado oil and gas operations are not known to have a significant problem with naturally occurring radioactive materials (NORM) or technologically enhanced naturally occurring radioactive materials (TENORM); however, there have been some instances where pipe scale has contained radium and associated radon gas. A NORM survey including site specific testing could be performed to further assess the radon potential at the site. 7. Nuisance Adjacent land uses will not be adversely impacted by the generation of vapor, dust, smoke, glare or vibration generated by the storage use beyond the limits set forth by Garfield County, the COGCC, the CDPHE and other regulatory agencies. 8. Hours of Operation The Ramos Laydown Yard will be accessible to Noble personnel 24 hours a day, year round. Materials will be picked-up and dropped-off on an as-needed basis. No personnel will be stationed at the facility on a regular basis. Noble Energy Inc.

Ramos Laydown Yard OA Project No. 013-2329-100 United States Department of Agriculture A product of the National Cooperative Soil Survey, a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local participants Custom Soil Resource Report for Rifle Area, Colorado, Parts of Garfield and Mesa Counties Noble Ramos Laydown Yard Natural Resources Conservation Service March 18, 2014 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.nrcs.usda.gov/wps/portal/ nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (http:// offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/? cid=nrcs142p2_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 scientists classified and named the soils in the survey area, they compared the 5 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 identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately.

Custom Soil Resource Report 9 Map Unit Legend Rifle Area, Colorado, Parts of Garfield and Mesa Counties (CO683) Map Unit Symbol Map Unit Name Acres in AOI Percent of AOI 56 Potts loam, 6 to 12 percent slopes 11.1 100.0% Totals for Area of Interest 11.1 100.0% Map Unit Descriptions The map units delineated on the detailed soil maps in a soil survey represent the soils or miscellaneous areas in the survey area. 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 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. Custom Soil Resource Report 10 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.

Building Site Development Building site development interpretations are designed to be used as tools for evaluating soil suitability and identifying soil limitations for various construction purposes. As part of the interpretation process, the rating applies to each soil in its described condition and does not consider present land use. Example interpretations can include corrosion of concrete and steel, shallow excavations, dwellings with and without basements, small commercial buildings, local roads and streets, and lawns and landscaping. Corrosion of Concrete "Risk of corrosion" pertains to potential soil-induced electrochemical or chemical action that corrodes or weakens concrete. The rate of corrosion of concrete is based mainly on the sulfate and sodium content, texture, moisture content, and acidity of the soil. Special site examination and design may be needed if the combination of factors results in a severe hazard of corrosion. The concrete in installations that intersect soil boundaries or soil layers is more susceptible to corrosion than the concrete in installations that are entirely within one kind of soil or within one soil layer. The risk of corrosion is expressed as "low," "moderate," or "high." 13 14 Custom Soil Resource Report Map—Corrosion of Concrete 43 6 2 5 9 0 43 6 2 6 2 0 43 6 2 6 5 0 43 6 2 6 8 0 43 6 2 7 1 0 43 6 2 7 4 0 43 6 2 7 7 0 43 6 2 8 0 0 43 6 2 8 3 0 43 6 2 8 6 0 43 6 2 5 9 0 43 6 2 6 2 0 43 6 2 6 5 0 43 6 2 6 8 0 43 6 2 7 1 0 43 6 2 7 4 0 43 6 2 7 7 0 43 6 2 8 0 0 43 6 2 8 3 0 43 6 2 8 6 0 753000 753030 753060 753090 753120 753150 753180 753210 753030 753060 753090 753120 753150 753180 753210 39° 22' 41'' N 10 8 ° 3 ' 4 6 ' ' W 39° 22' 41'' N 10 8 ° 3 ' 3 6 ' ' W 39° 22' 32'' N 10 8 ° 3 ' 4 6 ' ' W 39° 22' 32'' N 10 8 ° 3 ' 3 6 ' ' W N Map projection: Web Mercator Corner coordinates: WGS84 Edge tics: UTM Zone 12N WGS84 0 50 100 200 300 Feet 0 20 40 80 120 Meters Map Scale: 1:1,430 if printed on A portrait (8.5" x 11") sheet.

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. Depth to Any Soil Restrictive Layer A "restrictive layer" is a nearly continuous layer that has one or more physical, chemical, or thermal properties that significantly impede the movement of water and air through the soil or that restrict roots or otherwise provide an unfavorable root environment. Examples are bedrock, cemented layers, dense layers, and frozen layers. This theme presents the depth to any type of restrictive layer that is described for each map unit. If more than one type of restrictive layer is described for an individual soil type, the depth to the shallowest one is presented. If no restrictive layer is described in a map unit, it is represented by the "> 200" depth class. 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.

The Ecological Site Assessment section includes ecological site descriptions, plant growth curves, state and transition models, and selected National Plants database information. All Ecological Sites — Rangeland An "ecological site" is the product of all the environmental factors responsible for its development. It has characteristic soils that have developed over time; a characteristic hydrology, particularly infiltration and runoff, that has developed over time; and a characteristic plant community (kind and amount of vegetation). The vegetation, soils, and hydrology are all interrelated. Each is influenced by the others and influences the development of the others. For example, the hydrology of the site is influenced by development of the soil and plant community. The plant community on an ecological site is typified by an association of species that differs from that of other ecological sites in the kind and/or proportion of species or in total production. An ecological site name provides a general description of a particular ecological site. For example, "Loamy Upland" is the name of a rangeland ecological site. An "ecological site ID" is the symbol assigned to a particular ecological site. The map identifies the dominant ecological site for each map unit, aggregated by dominant condition. Other ecological sites may occur within each map unit. Each map unit typically consists of one or more components (soils and/or miscellaneous areas). Each soil component is associated with an ecological site. Miscellaneous areas, such as rock outcrop, sand dunes, and badlands, have little or no soil material and support little or no vegetation and therefore are not linked to an ecological site. The table below the map lists all of the ecological sites for each map unit component in your area of interest.

According to Section 7-108 Use of Land Subject to Natural Hazards of the Garfield County LUDC, “Land subject to identified Natural and Geologic Hazards, such as falling rock, landslides, snow slides, mud flows, radiation, flooding, or high water tables, shall not be developed unless it has been designed to eliminate or mitigate the potential effects of hazardous site conditions as designed by a qualified professional engineer and as approved by the County.” The LUDC requires a Natural and Geologic Hazard Study be prepared by a qualified professional geologist be submitted with a development plan or plat. The LUDC defines a geologic hazard as “A geologic phenomenon that is so adverse to past, current, or foreseeable construction or land use as to constitute a significant hazard to public health and safety or to property.” The LUDC defines a Hazard Area as “An area that contains or is directly affected by a geologic hazard, including but not limited to the following types of areas.” A. Avalanche Area. “A mass of snow or ice and other material that may become incorporated therein as such mass moves rapidly down a Slope.” B. Landslide Area. “An area with demonstrably active mass movement of rock and soil where there is a distinct surface rupture or zone of weakness that separates the landslide material from more stable underlying material.” C. Mudflow Debris Area. “An area subject to rapid mud and debris movement or deposit occurring after mobilization by heavy rainfall or snowmelt runoff. Such areas are formed by successive episodes of deposition of mud and debris.” D. Radioactive Area. “An area subject to various types of radiation emission from radioactive minerals that occur in natural or manmade deposits of rock, soil, or water.” E. Potentially Unstable Soils. “An area of land identified as having soils that may cause damage to structures, such as buildings and roadways, as a result of over saturation or some other outside influence.” According to the Garfield County LUDC Section 4-203 Description of Submittal Requirements, the professional qualifications for preparation and certification of certain documents required by this Code are as follows: “Geologist. Geology reports shall be prepared by either a member of the American Institute of Professional Geologists, a member of the Association of Engineering Geologists, or a qualified geotechnical engineer licensed in the State of Colorado.” Geologic Hazard Report Olsson Associates Noble Ramos Laydown Yard Golden, Colorado Garfield County, CO December 2013 ii A search of the Colorado Department of Regulatory Agencies (DORA) Licensed Professionals and Businesses, indicates that Colorado licenses “professional engineers” and “engineer interns” but does not appear to have a license specific to “geotechnical engineers.” Currently, the state of Colorado does not require licensure or registration of geologists. Colorado Revised Statutes do require that geologic reports be prepared or authorized by a professional geologist. However, “Professional Geologist” is a term defined in Colorado Statutes.

The site lies at an elevation greater than 5,840 feet above mean sea level (amsl) as shown on the attached Vicinity Map – V1. The purpose of this report is to identify geologic conditions that may pose hazards to a land development project in order that appropriate mitigation or avoidance techniques may be implemented as described in the Garfield County LUDC. According to the Garfield County LUDC, Section 7-207, the types of natural and geologic hazards identified pertain to the following: A. Utilities; B. Development in Avalanche Hazard Areas; C. Development in Landslide Hazard Areas; D. Development in Rockfall Hazard Areas; E. Development in Alluvial Fan Hazard Areas; F. Slope Development; G. Development on Corrosive or Expansive Soils and Rock; H. Development in Mudflow Areas; and I. Development Over Faults. This report presents Olsson findings following an evaluation of these and other geologic hazards potentially affecting the site and proposed development. The Ramos laydown yard (Site) was found to be suitable for the proposed development. Geologic hazards or potential geologic hazards were not identified in the immediate vicinity of the Site. The potential exists for geologic hazards to exist in surrounding areas and in other parts of Garfield County. Steep slopes are found in areas to the south of Section 1 along the along the Spring Creek drainage, which could result in rock fall hazards. Steep slopes may be an issue in the vicinity of the proposed laydown yard since slopes have been identified as severely limiting development. Engineering controls will need to be taken into consideration with the proposed development, but should be feasible considering the nature of the proposed development. This report should be read in its entirety, including but not limited to the conclusions and recommendations in section 4.0. Geologic Hazard Report Olsson Associates Noble Ramos Laydown Yard Golden, Colorado Garfield County, CO December 2013 2 2.0 GENERAL SITE LOCATION AND BACKGROUND Noble contracted Olsson Associates (Olsson) to conduct a natural and geologic hazards assessment as part of the proposed development of the Ramos Laydown Yard. The proposed yard will be used to store sections of pipe and other equipment and will not involve the construction of permanent or occupied structures. The following sections provide information about the proposed development and the site geologic setting. The site surface and bedrock geology is shown on the Geology Map – G1. 2.1 Project and Site Description The proposed Ramos Laydown Yard site is to be located off of Spring Creek Road approximately three miles south of the towns of Parachute and Battlement Mesa. 2.2 Structural Geology The proposed laydown yard is located in the southeastern part of the Piceance Basin. The Piceance Basin is an irregularly-shaped elongated basin formed by tectonic forces associated with the Laramide orogeny. These tectonic forces down warped the earth’s crust and formed the Piceance Basin as a result of the uplift of the surrounding Colorado Rocky Mountains and the Colorado Plateau. The Piceance Basin is the major structural geologic feature in the region. It is bound to the east by the Grand Hogback monocline, the White River Uplift to the northeast, the Gunnison Uplift to the south, the Uncompahgre Uplift to the south and southwest, the Douglas Creek Arch to the west-northwest, and the axial basin uplift to the north (Grout and Verbeek, 1992). A fault is a fracture in rock along which movement has occurred. Mountains are bound by faults and are a visible indication of a structural weakness in the earth’s crust. The Colorado Rocky Mountains are bound by faults; however, these faults are not always visible at the ground surface either because the fault trace is ‘blind’ meaning that the fault does not have surface expression since it does not cut across overlying sedimentary bedrock units, or that it has been buried and concealed by unconsolidated sediments deposited over the area where the faults are present. 2.3 Site Bedrock Geology Olsson reviewed the Geologic Map of the Housetop Mountain Quadrangle, Garfield and Mesa Counties, Colorado (Donnell, Yeend, and Smith, 1989). The bedrock geology as shown on the attached Geologic Map, consists of the Tertiary (Eocene epoch) Shire Member of the Wasatch Formation. The Shire Member consists of variegated purple, lavender, red, gray, and brown claystones with some locally lenticular, fine- to coarse-grained sandstone and conglomerate, and thin limestone beds. The thickness of the Wasatch Formation Shire Member is about 900 feet to 1,700 feet, while the maximum exposed thickness of the Wasatch Formation is about 800 feet. Geologic Hazard Report Olsson Associates Noble Ramos Laydown Yard Golden, Colorado Garfield County, CO December 2013 3 2.4 Site Surficial Geology The surficial geology onsite consists of older Quaternary gravels and alluvium of pre-Bull Lake Age (Qgo) or pediment gravels consisting of pebbles, cobbles, and boulders of nearly equal amounts of basalt and sedimentary rock fragments of locally derived sandstone, claystone, and marlstone. The matrix consists of greenish-gray silty sand. Reddish-brown windblown silt and sand locally mantle terrace surfaces. These deposits range in thickness from 10 feet to 60 feet with thicker deposits near the Colorado River. (Donnell, Yeend, and Smith, 1989). The pediment gravels consist of basalt boulders and weathered shale, marlstones, siltstones and sandstones from the Wasatch and Green River Formations found at higher elevations on Battlement Mesa. The pediment gravels form extensive deposits that border the Colorado River between Rifle and De Beque and are mantled with poorly-sorted, coarse-grained gravels of pre- Bull Lake age. Log Mesa, High Mesa, and Samson Mesas are some of the local names given to these gravel covered pediments. The pediments overlie gently dipping sandstones, siltstones, and claystones of Wasatch Formation (Yeend, 1969). The floors of Wallace Creek, Spring Creek, and Pete and Bill Creek on the northwest side of Battlement Mesa are mantled with alluvial gravel of Pinedale age and overlie the older pediment gravels (Yeend, 1969). These alluvial deposits are reworked glacial deposits of later Pinedale age. 2.5 Soil The Soils Map – S1 shows the area soil types. Soils, consisting of the following units, are within the study area around the proposed laydown yard:  Potts loam (Unit 56): The Potts loam is a deep well-drained, moderately sloping to rolling soil found on mesas, benches, and the sides of valleys at elevations ranging from 5000 feet to 7000 feet. The Potts loam formed in alluvium derived from sandstone, shale, or basalt. The permeability is moderate, and available water capacity is high. Surface runoff is medium, and the erosion hazard is severe.  Potts-Ildefonso complex (Unit 58): The Potts-Ildefonso complex soils are strongly sloping to hilly soils formed on mesas, alluvial fans, and the sides of valleys with 12% to 25% slopes. The Potts soil formed in alluvium derived from sandstone, shale, or basalt and makes up 60 percent of this unit while the Ildefonso soil formed in calcareous, basaltic alluvium, and small amounts of eolian material and makes up about 30% of the unit. The Potts-Ildefonso soils are deep, well drained, permeability is moderate to moderately rapid, and the available water capacity is high. The surface runoff of these soils is medium, and the erosion hazard is moderate. The Soil Survey of the Rifle Area, Parts of Garfield and Mesa Counties, (Harman and Murray, 1985) contains tables that give estimates of engineering properties and classifications of the major horizons of each soil in the survey area for building site development. Community development and recreational developments are limited by the Geologic Hazard Report Olsson Associates Noble Ramos Laydown Yard Golden, Colorado Garfield County, CO December 2013 4 low strength, shrink-swell potential, and the slopes of these soils. Roads and other development can be designed to accommodate these limitations. 2.6 Hydrologic Setting The hydrology of the area around the proposed laydown yard is controlled by Spring Creek located approximately 0.2 miles to the south of the proposed Site. Wallace Creek is located to the southwest of Spring Creek, and Pete and Bill Creek is located to the northeast of the proposed Site. These streams drain to the north - northwest toward their confluences with the Colorado River. Groundwater within the unconsolidated Quaternary age deposits is expected to follow topography and flow parallel and toward these drainages. 2.7 Aquifers An aquifer is defined as a geological formation, group of formations, or part of a formation that is capable of yielding a significant amount of water to a well or spring. Based on data from the Colorado Division of Water Resources, groundwater in the Quaternary age alluvial sediments is likely to be encountered within the alluvium at depths of more than 200 feet below ground surface (bgs), and records indicate that water wells in the area have total depths ranging from 250 feet to 300 feet bgs. Several springs have been observed and are shown on the Surface Water Map (SW-1) along the banks of Spring Creek where groundwater discharges to the Spring Creek drainage. The Wasatch Formation is a confining unit and serves as the base for groundwater in the Quaternary age alluvium and pediment gravels. The Wasatch Formation can be as much as 5,000 feet thick, and locally contains sandstone lenses that yield water of limited quantity and quality to wells. The Tertiary (Paleocene Epoch) Fort Union Formation underlies the Wasatch Formation, and is locally considered an aquifer; however, it is limited to a thin layer of coarse- grained sandstone on the northeastern side of the Piceance Basin. The Mesaverde aquifer comprises water-yielding units in the Upper Cretaceous Mesaverde Group, its equivalents, such as the Ohio Creek Member, and some adjacent Tertiary formations, such as the Fort Union Formation. The quality of the water in the Mesaverde aquifer is extremely variable, and in most areas of the Mesaverde aquifer, groundwater withdrawals have been small. The water quality can be very good with total dissolved solids (TDS) concentrations less than 1,000 milligrams per liter (mg/l) in areas along the margin of the basin, but locally, the TDS can be very large to more than 35,000 mg/l where the water is too saline for most uses (Robson and Banta, 1995). The Mesaverde aquifer is not likely to be impacted by the proposed project due to the thickness and minimal permeability of the Wasatch Formation (Topper et al, 2003). Geologic Hazard Report Olsson Associates Noble Ramos Laydown Yard Golden, Colorado Garfield County, CO December 2013 5 3.0 NATURAL AND GEOLOGIC HAZARD ASSESSMENT The following sections present the assessment of geologic hazards in the vicinity of the proposed Ramos Laydown Yard. The Vicinity Map shows the proposed laydown yard in relation to the affected parcel and local roads. 3.1 Utilities Installations of buried utilities are not expected to be associated with the construction of the proposed laydown yard. Therefore, geologic hazards associated with trenching or excavation for the placement of buried utilities is not expected to affect the proposed project. The laydown yard will be used to store sections of pipe and equipment above grade for use elsewhere in the area and region. 3.2 Avalanche Hazard Area The site is not located in a known avalanche hazard area. Winters are cold in the mountainous areas of Garfield County, and valleys are colder than the lower parts of adjacent mountains due to cold air drainage. Average seasonal snowfall in Garfield County is 50 inches. The greatest snow depth at any one time during the period of record from 1951 to 1974 was 29 inches recorded at Rifle, Colorado approximately 30 miles to the east of the proposed site. Much of the Rifle area is at a higher elevation than the town of Rifle and areas to the west. Parts of eastern Garfield County are somewhat cooler and receive more precipitation. Avalanches are not expected to affect the proposed laydown yard since it is located at elevations between 6000 feet and 8000 feet. Avalanches are the most dangerous geologic hazard in Colorado resulting in injuries, loss of life, and about $100,000 in direct property damage, and indirect economic losses in the millions of dollars annually. However, the avalanche prone areas include the Park Range and Flat Tops in northeastern Garfield County, Colorado, to the north of Glenwood Springs. Glenwood Springs, near the east edge of the area, averages about one degree cooler than Rifle and receives about five inches more precipitation per year (Harman and Murray, 1985). 3.3 Landslide Areas or Potential Landslide Hazard Areas Landslides in Colorado in the western part of the state are typically associated with areas of significant slopes where landslides are natural and ongoing events. Landslides can be triggered by human activities disrupting the land and periods of precipitation which increase the chances of landslide occurrence. According to the Garfield County GIS Surficial Geology map, the areas to the southwest of the town of Parachute and on the south side of the Colorado River have not been mapped for landslide potential. According to the Geologic map of Surficial Deposits in the Grand and Battlement Mesas Area, Delta, Mesa, and Garfield Counties, Colorado, the site is located in an area of Pleistocene age pediment gravels estimated to have been deposited pre- Bull Lake age glaciation. The nearest mapped landslide deposits are located to the north in Township 7 South, Range 96 West. Geologic Hazard Report Olsson Associates Noble Ramos Laydown Yard Golden, Colorado Garfield County, CO December 2013 6 3.4 Rockfall Areas The site is not located within an area that has been mapped as having rockfall or potential for rockfall. Potential rockfall areas are present to the west along Log Mesa where piedmont gravels lie along steep slopes in the southwest part of Section 12. 3.5 Alluvial Fan Hazard Areas The site is located in an area of pediment gravel. Areas closer to the Colorado River near Township 7 South, Range 96 West, have been mapped as alluvial fans, alluvial terrace and fan- gravel deposits. Alluvial fan areas are located along the flanks of Flatiron Mesa and Grass Mesa, and pediment gravels along the Wallace Creek and Pete and Bill Creek drainages. These alluvial sediments were transported down from higher elevations on Battlement Mesa and prograded out over outcrops of the Wasatch Formation pediment. Outwash gravels and reworked glacial alluvium deposited by retreating glaciers are present in the major stream valleys in the area. The present streams have cut narrow valleys into these alluvial fill and fan deposits. Poorly sorted alluvial fan deposits are present along the sides of tributaries where they empty into the Colorado River. 3.6 Unstable or Potentially Unstable Slopes According to the Garfield County Slope Hazard Study Areas, the areas south of the Colorado River and the towns of Parachute and Battlement Mesa, Colorado, have not been mapped to document slope hazards. Areas to the north of the town of Parachute have been mapped as being in an area of major slope hazards. Site specific investigations should be conducted to assess active landslide areas. According to the Garfield County Slope Hazard Study Areas 1, 2 & 3 Map, geologic studies may include intensive drilling and sophisticated strength testing, stability analyses, and monitoring of soil, rock, and groundwater conditions. Mitigation may be possible, but likely will be expensive, may require special siting, and will involve some risk. Avoidance may be recommended for projects of lower economic value (Garfield County, Slope Hazard Study 2002). 3.7 Corrosive or Expansive Soils and Rock The Garfield County Soil Hazard Profile Study Areas 1, 2 & 3 map does not extend to the south of the towns of Parachute and Battlement Mesa. Soil hazards are shown in the eastern part of Garfield County. These conditions are not expected to be present in the area of the laydown yard. The proposed laydown yard is not located in an area known to have corrosive or expansive soil or rock types based on a review of the site geology. No permanent structures are to be built. Sedimentary rock containing high salt content, such as chloride or sulfate, and soils derived from these rock types, may be corrosive to concrete or metal, causing damage to structures built upon them. These conditions exist elsewhere in the region, but are not expected to be present in the vicinity of the laydown yard site. Geologic Hazard Report Olsson Associates Noble Ramos Laydown Yard Golden, Colorado Garfield County, CO December 2013 7 Some Tertiary and Cretaceous age sedimentary rocks with high clay content are capable of accepting water into their chemical structure and expand many times their volume when dry. These sedimentary rocks, and soils formed from these rock types, may expand or contract as they become wet and then dry out resulting in damage to structures built upon them. 3.8 Mudflow and Debris Fan Areas The proposed laydown yard is located in an area that is underlain with pre-Bull Lake alluvium gravel deposits and older pediment gravels locally mantled with eolian sediments. (Donnell, Yeend, and Smith, 1989). There are no mapped mudflow or debris fan areas in the immediate vicinity of the proposed laydown yard. Mudflow and debris fan areas have been mapped to the south of the Colorado River drainage in areas further to the east. These are areas where unconsolidated sediments have eroded from higher elevations and have been deposited on top of the Wasatch Formation. Landslide areas are shown on the surficial geology Garfield County GIS map revised June 2007. These landslide areas are to the southeast of the town of Rifle on the south side of the Colorado River floodplain. Weak claystone units within the Wasatch have been known to fail due to saturated conditions resulting in slides of these unconsolidated materials. 3.9 Development Over Faults Based on a review of Colorado’s Earthquake and Fault Map (Morgan, 2007), major faults are not known in the project area. Faults have not been mapped at the surface in the project area according to USGS Professional Paper 617, Plate 1 (Yeend, 1969) or on the Geologic Map of the Housetop Mountain Quadrangle (Donnell, Yeend, and Smith, 1987). The Piceance Basin and other Tertiary age basins of the Colorado are bound along at least one margin by monoclines, such as the Grand Hogback to the east near the town of Rifle, which were thought to have formed by reactivation of pre-existing, steeply dipping fault zones in the Precambrian basement rock. Recent seismic data suggests that some of the monoclines, especially in the Rocky Mountain foreland near the boundary with the Colorado Plateau, overlie a west-, southwest-, or south-directed thrust fault system. These blind thrust faults transect older Mesozoic and Paleozoic sedimentary rocks that resulted from two major deformational events associated with the uplift of the ancestral Rocky Mountains. The Grand Hogback monocline formed above the tip of a blind, Precambrian basement rock thrust fault wedge which moved southwest and west-southwest into the Piceance basin (Grout and Verbeek, 1992). Several northwest-trending faults are present on the north side of Plateau Creek to the south of the area. They cut rocks as young as the upper Wasatch and possess throws of less than 150 feet (Yeend, 1969). There are no major faults in the area of the central Roan Plateau area to the north. Three narrow grabens have been mapped along a northwest trending fracture zone to the north in the central part of Township 4 South, Range 97 West, and along a graben in the southwestern part of Township 4 South, Range 96 West, suggesting that these grabens lie along a single fracture zone that extends for approximately 9 miles. Maximum measured Geologic Hazard Report Olsson Associates Noble Ramos Laydown Yard Golden, Colorado Garfield County, CO December 2013 8 stratigraphic displacements along these faults do not exceed 120 feet, and most are considerably less (Hail, 1992). Colorado is considered a region of minor earthquake activity; however, there is uncertainty due to the relatively short historic record. According to the USGS Colorado Earthquake History online, newspaper accounts were the primary source of earthquake data in Colorado prior to 1962. Few earthquakes have been reported in this part of Colorado. A very minor earthquake occurred in the northwestern part of Colorado on November 22, 1982 at 3:09 a.m. MST. The magnitude 2.9 earthquake was located about 18 miles northeast of the town of Rifle and was felt at a fish hatchery in the area. The largest quake in the area occurred on April 22, 1984 and had a magnitude of 3.1 on the Richter scale. The quake was felt in Carbondale and in Glenwood Springs. Of the hundreds of quakes that occurred in the Carbondale area during that time period, 12 were reported as felt. The western part of Colorado experienced four earthquakes during September and October of 1990. On October 18, 1990, two earthquakes occurred - the first at 6:32 p.m. MDT and the second at 6:43 p.m. MDT. Both earthquakes were located about 22 miles west of Glenwood Springs in the vicinity of the town of New Castle. The earthquakes had magnitude of 2.3 and 2.1. On December 12, another very minor earthquake of 2.7 magnitude was centered and felt near the town of New Castle. 3.10 Flood Prone Areas The laydown yard is not located in a flood prone area. According to available information from the Federal Emergency Management Agency (FEMA) National Flood Insurance Program, Flood Insurance Rate Map (FIRM), the site is not located within the 100-year floodplain or 500-year floodplain. The Floodplain map of the town of Parachute shows the floodplain along the Colorado River drainage which is several miles north of the proposed laydown yard site location. Flash flood conditions are a potential concern along the Spring Creek and the Pete and Bill Creek drainages. 3.11 Collapsible Soils Collapsible soils are another type of subsidence that occurs in parts of Colorado where unconsolidated sediments are present. This ground settlement can damage man-made structures such as foundations, pavements, concrete slabs, utilities, and irrigation works. These conditions are not expected in the vicinity of the proposed laydown yard. Hydrocompactive soils are the most common type of collapsible soils. The presence or introduction of water causes the soils to compact once they become wet. Hydrocompactive soils form in semi-arid to arid climates in the western United States and large parts of Colorado in specific depositional environments. Collapsible soils have a low density and low moisture content where the grains are not packed tightly together, and are strong under dry conditions. The loose, skeletal, fabric of these soils is Geologic Hazard Report Olsson Associates Noble Ramos Laydown Yard Golden, Colorado Garfield County, CO December 2013 9 preserved when the soil is dry because the grains are “tack-welded” due to the presence of binding agents, such as clay or silt, soil suction pressures, or other binding agents. These binding agents can break, soften, disperse, or dissolve when the soils become wet causing subsidence or settling. Silty clay and clayey sandy soils onsite are potentially collapsible, although less likely onsite than subsidence due to expansive soils. Collapsible soil conditions may be present in alluvial fan, alluvial, colluvial, and eolian depositional environments, and are found in some areas along the Colorado River drainage where fine-grained sediments have been deposited from higher elevations, but are not expected to be present in the vicinity of the proposed laydown yard site. 3.12 Mining Activity A review of the Grand Valley 7.5-minute quadrangle and the Housetop Mountain 7.5-minute topographic quadrangle maps did not show any mining activities in close proximity to the proposed laydown yard. Natural gas wells are shown in the areas to the north of the proposed laydown yard right-of-way. 3.13 Radioactivity According to Colorado Geologic Survey Bulletin 40, Radioactive Mineral Occurrences of Colorado, the only naturally occurring radioactive mineral occurrences in Garfield County include uranium and vanadium deposits that occur near the town of Rifle (Nelson-Moore, Collins, Hornbaker, 2005). This site is located more than 30 miles to the northeast of the proposed Ramos laydown yard. According to the Vanadium-Uranium Deposits of the Rifle Creek Area, Garfield County, Colorado, U.S.G.S. Bulletin 1101, these deposits are located approximately 13 miles northeast of the town of Rifle and are hosted in older Jurassic age sediments, are not exposed in the vicinity of the site, and lie stratigraphically below the zones that are developed for oil and gas production. The Colorado Department of Public Health and Environment (CDPHE) has posted a statewide radon potential map on their website based on data collected by the EPA and the U.S. Geological Survey. Garfield County and most of Colorado has been mapped as being within Zone 1 – High Radon Potential, or having a high probability that indoor radon concentrations will exceed the EPA action level of 4 picocuries per liter (pCi/L). Radon is not expected to be a significant problem at the proposed site since the development will not include any permanent structures, personnel will not be onsite for extended periods, and the site will not be developed with structures containing basements or substructures in which radon can accumulate. Colorado oil and gas operations are not known to have a significant problem with naturally occurring radioactive materials (NORM) or technologically enhanced naturally occurring radioactive materials (TENORM); however, there have been some instances where pipe scale has contained radium and associated radon gas. A NORM survey including site specific testing could be performed to further assess the radon potential at the site. Geologic Hazard Report Olsson Associates Noble Ramos Laydown Yard Golden, Colorado Garfield County, CO December 2013 10 4.0 Conclusions and Recommendations The following conclusions and recommendations were made following a review of the available site data for natural and geologic hazards in the vicinity of Noble’s proposed laydown yard located in Garfield County, Colorado.  Geological hazards are not expected to be associated with the installation of buried utilities since the proposed laydown yard is not expected to have any buried utility lines.  Avalanche areas are present in the northeastern parts of Garfield County in parts of the Park Range and Flat Tops mountain range. Avalanche conditions are not expected to be present in area of the Site.  Rockfall areas are present in some areas of the steep canyons and narrow drainages incised by area streams, but are not expected to be a hazard in the vicinity of the Site.  Alluvial fan hazard areas are present along parts of the Colorado River drainage where tributary drainages from higher elevations have deposited sediments onto bedrock overlying the Wasatch Formation. These conditions are not present in the vicinity of the Ramos laydown yard.  The soil onsite has been mapped as the Potts Loam. Community development and recreation are limited for the Potts Loam by low-strength, shrink-swell potential, and slope. Considering the nature of the proposed development, the low-strength and shrink- swell potential of the soils are not expected to affect the laydown yard. Slope development may be an issue in the vicinity of the proposed laydown yard, since based on the descriptions of the soil type, slopes have been identified as moderately to severely limiting for development. Engineering controls will need to be taken into consideration with the proposed development. Therefore, slopes may be a hazard in the laydown yard area.  Corrosive or expansive soils and rock are not expected to be present in the vicinity of the proposed laydown yard site.  Collapsible soils are not present in the vicinity of the proposed laydown yard site.  No significant faulting is known in the laydown yard site.  No flood prone areas are mapped in the vicinity of the site. Flash flooding is an issue for lower elevations along Spring Creek, Wallace Creek, Pete and Bill Creek and areas along the Colorado River are prone to flood risks.  There are no mining activities shown in the vicinity of the site.  There are no naturally occurring radioactive mineral deposits known in the site area. NORM/TENORM may be an issue with exploration and production and could be an issue with used pipe scale.

Section 4-203.G requires proposed developments to describe existing conditions and potential changes created by the proposed land use change. The purpose of this report is to determine the environmental impacts (Section 4-203.G(8)) of the proposed development on wildlife habitat, the creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, and changes in habitat use by wildlife. The Ramos Laydown Yard is located in the NE¼ of the SW ¼ of Section 1, Township 8S, Range 96W of the 6th P.M. in Garfield County, CO (Figure L1). This site is an existing laydown yard adjacent to the Ramos 1-36 well pad. This site is currently being used as a laydown yard and is absent of any wildlife habitat and/or vegetation. This site currently has an existing fence that runs along the perimeter. 2.0 Survey Methods A preliminary review of the Ramos Laydown Yard was conducted to familiarize Olsson with the site and to determine the presence/absence of threatened, endangered, or sensitive wildlife and plant species, raptors, Birds of Conservation Concern (BCC), and migratory and non-migratory birds. The review utilized aerial photographs and Geographic Information Systems (GIS) which included those species listed by County according to the U.S. Fish and Wildlife Service (USFWS) Information, Planning, and Conservation System (IPAC) (USFWS 2013). Species identified by IPAC were further evaluated for overlapping range data encompassing the project location site. Range data for rare species was reviewed from the Colorado Parks and Wildlife (CPW) Natural Diversity Information source (NDIS) ArcGIS website for locations of rare plants and animals. Colorado Oil and Gas Conservation Commission (COGCC) GIS data for wildlife habitat, dated 2013, also was utilized. Additionally, species located in the range of the project location site were further reviewed for critical habitat. Field data collected during the survey were documented and/or recorded using GPS utilizing the NAD83 map datum, with all coordinate systems based on the Universal Transverse Mercator (UTM) coordinate system in Zone 12. The Ramos Laydown Yard was surveyed in 2009 for permitting purposes by WestWater Engineering; this was predominately a weed and wildlife survey. During this field observation, present vegetation and weeds were documented along with any wildlife sign (Figure 1). A raptor nest was found in a 30 foot juniper tree that was located within the old growth juniper woodland in Spring Creek drainage. This nest was vacant at the time of the survey and in poor/fair condition. In addition to finding the nest, WestWater biologists found deer sign, cottontail rabbits, meadowlarks and western bluebirds (Appendix A). On November 26, 2013, an Olsson biologist conducted surveys of the project site and the surrounding area to reassess the site facilities since the last survey and to determine any additional potential impacts to wildlife habitat. If potential habitat was available for raptors or special status wildlife species, surveys were conducted on foot through suitable habitats for these species within 0.25 miles of the site. Vegetation types were determined during an on-site field identification of plant species and community types. Plant identification was conducted by a trained plant ecologist with the aid of several published field guides (CWMA 2013, Weber 2012 3rd edition, Whitson et al. 2006). Noble Energy, Inc. Ramos Laydown Yard Wildlife and Vegetation Impact Analysis Page 2 Olsson Associates Photographs of the laydown yard location, as well as the surrounding area located within the site, were taken to record general biological communities, site conditions, and terrain. As this survey was conducted in the late fall, it is recommended that a follow-up survey be conducted in the spring. Please reference vegetation section below. Section 4-203.G (8) Environmental Impacts: Existing Environmental Conditions Waters of the U.S.-Army Corps of Engineers (ACOE) A desktop review for waterbodies and wetlands was evaluated by reviewing areas that could potentially be identified as Jurisdictional Waters of the United States (WOUS). Impacts to WOUS require compliance under Section 404 of the Clean Water Act (CWA). Section 404 of the CWA authorizes the United States Army Corps of Engineers (USACE) to issue permits for the discharge of dredge or fill materials into WOUS. Construction in areas that are WOUS may require a permit from the USACE depending on the type of project and associated WOUS impacts. Based on desktop review and on site surveys, Olsson determined that no wetlands or drainages would be affected by the site. Vegetation Assessment Olsson Associate’s trained ecologist conducted the vegetation assessment in the late fall when most of the plant species had senesced. The Ramos laydown yard is located in an area where the primary land uses include agricultural activities and natural gas development. The access road to the site runs through another Noble Energy Inc. (Noble) natural gas well pad, the Ramos 1-36 Pad. The laydown yard footprint will be on an area that has been stripped of all native vegetation and currently is being used as a laydown yard and storage facility. The pad contains an earthen berm around its perimeter that currently supports weed species. This project area will need to maintain the current weed management process(es) to control the existing conditions. The area of the proposed laydown yard is surrounded by a fence with a gate controlled by Noble. This fence is intended to prevent vehicles, livestock, and wildlife from entering the laydown yard area. The vegetation types located outside of the fenced area consist of sagebrush steppe, mixed grasslands, and pinyon-juniper communities. Mixed Grasslands The mixed grassland community is likely a result of the removal of the sagebrush steppe community. This community type is located on recontoured and vegetated fill and cut slopes. These areas are dominated by Crested Wheatgrass (Agropyron cristatum), Intermediate Wheatgrass (Thinopyrum intermedium), and Downy Brome (Bromus tectorum). Sagebrush Steppe The sagebrush steppe community is dominated by Big Sagebrush (Artemisia tridentata), and various other shrubs which includes Rubber Rabbitbrush (Ericameria nauseosa). Dispersed grasses and forbs make up the understory. Noble Energy, Inc. Ramos Laydown Yard Wildlife and Vegetation Impact Analysis Page 3 Olsson Associates Pinyon-Juniper The pinyon-juniper community is dominated by Two needle pinyon (Pinus edulis), and Utah Juniper (Juniperus osteosperma), with various grasses and forbs dispersed in the understory. Disturbance to vegetative communities is restricted to the confines of the existing project area footprint and should not directly impact the communities located outside of the project area. There is potential for the existing vegetation to be threatened by encroaching weed species from the previously disturbed project area (including roadways), and existing natural gas well pad. Species observed during the survey are shown in Table 1. Table 1- Common plant species observed within the immediate area of the laydown yard both in and outside of the fenced area.

Ramos Laydown Yard Wildlife and Vegetation Impact Analysis Page 4 Olsson Associates  Ute ladies’-tresses (Spiranthes diluvialis) None of the above mentioned species, or potential habitats, was located within the parcel of the proposed laydown yard site. Noxious Weeds Three Colorado State B-list weed species were found present in the surrounding area but not within the fenced laydown yard, Bull Thistle (Cirsium vulgare), Musk Thistle (Carduus nutans), and Houndstongue (Cynoglossum officinale). Houndstongue was reported in a previously conducted survey that can be found in Appendix A. Three Colorado State C-list species were found in the area. Cheatgrass (Bromus tectorum) was found both in the surrounding area and within the fenced laydown yard footprint. Common burdock (Arctium minus) was found in the stormwater drainage that runs down the right of way located to the south. Redstem filaree (Erodium cicutarium) was reported in a previously conducted survey that can be found in Appendix A. Because the field survey was conducted in the late fall when most of the plants had senesced, it is possible that other weed species occur on the project site and in the nearby area but were not detected. The vegetative community within the project area along the pad berm is dominated by annual weedy species. Species found included: Russian Thistle (Salsola iberica), Tumble mustard (Sisymbrium altissimum), Yellow sweetclover (Melilotus officinale), Squirreltail (Elymus elemoides), Purple Aster (Machaeranthera Canescens), Kochia (Kochia scoparium), and Common Sunflower (Helianthus annuus). None of the weed species found within the fenced laydown yard area are included in the Garfield County or Colorado Noxious Weeds Lists.

Noble Energy, Inc. Ramos Laydown Yard Wildlife and Vegetation Impact Analysis Page 5 Olsson Associates As outlined in Noble’s Noxious Weed Management Plan, the above mentioned weed species should be treated using the best available management tools for each species and situation. Please reference Noble Energy Inc. Noxious Weed Management Plan, located in Appendix B. Wildlife Threatened, Endangered, and Candidate Wildlife Species The Ramos Laydown Yard was evaluated for threatened, endangered, or sensitive wildlife species listed in Garfield County (Table 3) (USFWS 2013). According to the USFWS IPAC, there are ten federally listed threatened, endangered, and candidate wildlife species that have the potential to occur in Garfield County. Table 3- Federal Threatened, Endangered, and Candidate Wildlife Species for Garfield County. Common Name Scientific Name Status Habitat Present Birds Greater Sage Grouse Centrocercus urophasianus Candidate No Mexican Spotted owl Strix occidentalis lucida Threatened No Yellow-Billed Cuckoo Coccyzus americanus Candidate No Fish Bonytail chub Gila elegans Endangered No Colorado pikeminnow Ptychocheilus lucius Endangered No Greenback Cutthroat Trout Oncorhynchus clarki stomias Threatened No Humpback chub Gila cypha Endangered No Razorback sucker Xyrauchen texanus Endangered No Mammals Canada lynx Lynx canadensis Threatened No North American wolverine Gulo gulo luscus Proposed Threatened No Nine of the listed species in the above table do not have mapped habitat occurring within or near the site (CPW-NDIS 2013). Potential habitat is not present for the Mexican Spotted Owl, Yellow-billed Cuckoo, Greenback cutthroat trout, Canada Lynx, the North American wolverine, and for the four federally listed endangered fish species. The greater sage grouse (GrSG) has CPW-NDIS mapped historic habitat overlaying the site (Figure 2). GrSG mapped production (includes majority of nesting habitat), overall range, brood areas, winter range and severe winter range habitats all occur >10 miles northwest of the site across the Colorado River. COGCC GIS wildlife habitat data shows mapped lek sites occurring 17 miles to the northwest of the project area (Figure 3). The GrSG inhabits vast, continuous sagebrush communities. Sagebrush is present in the vicinity of the site; however, this habitat is limited and highly fragmented. Additionally, the amount of disturbance from oil and gas pads, pipelines, and agricultural land would preclude sage grouse use of the area. Raptors Several raptor species or birds of prey, may potentially occur (nest, forage reside, or pass through) in areas surrounding the site (Table 4). The most common raptors that could potentially occur within the area are the American kestrel, Coopers hawk, Golden Eagle, Long- eared Owl, Northern Goshawk, Northern Harrier, Northern Saw-whet owl, Prairie Falcon, Red- tailed hawk, and Sharp-shinned Hawk. A previous survey was conducted in March 31, 2009 by WestWater (Appendix A & Figure 1). During this survey, a raptor nest was found within 0.5 miles of the site, in the Spring Creek Noble Energy, Inc. Ramos Laydown Yard Wildlife and Vegetation Impact Analysis Page 6 Olsson Associates drainage, south of the laydown yard. This raptor nest was unoccupied with no evidence of use, and the nest was found in poor condition. Olsson conducted a survey on November 26, 2013 to determine if any potential raptor nesting habitat was present, including attempting to locate the previously recorded nest. Overall, raptor nesting habitat is limited surrounding the site. The typical raptor nesting season occurs from February 15-August 15 depending on the species. Table 4- Raptor species that could occur (nest or forage) near the site. Common Name Scientific Name Preferred habitat BCC* American Kestrel Falco sparverius Nests in a wide variety of open country with scattered trees. Can include cottonwood, pinyon/juniper, ponderosa pine, Doug-fir, aspen, and spruce-fir. No Coopers Hawk Accipiter cooperii Cottonwood riparian to spruce/fir forests. Ponderosa pine, Doug-fir, lodgepole pine, aspen and pinyon- juniper woodlands No Golden Eagle Aquila chrysaetos Grasslands, sagebrush, farmlands, pinyon-juniper woodlands, and ponderosa pine forests. Prefers to nest on cliffs but will utilize trees. Yes Long-eared Owl Asio otus Occupies sagebrush, desert shrub, grassland, mountain meadows adjacent to thick cover. Roosts and nests in riparian, Gambel oak, willow and on the edges of dense stands of pinyon-juniper, Doug-fir, and spruce- fir No Northern Goshawk Accipiter gentilis Occupies coniferous forests, preferably in higher elevations.

No Northern Saw-whet owl Aegolius acadicus Nests in pinyon-juniper, narrowleaf cottonwood, ponderosa pine, Doug-fir, aspen, and mixed montane forests. No Prairie Falcon Falco mexicanus Nests on cliffs adjacent to open grassland, shrubland, or alpine tundra. Yes Red-tailed Hawk Buteo jamaicensis Occupies many different habitat types including grasslands, pinyon-juniper woodlands, deciduous, coniferous, and riparian forests. Will nest in mature trees or cliffs and utility poles. No Sharp-Shinned Hawk Accipiter striatus Nests primarily in coniferous forests and is known to hunt in a variety of woodland and forest habitats from pinyon-juniper to aspen and spruce/fir. No *BCC=U.S. Fish and Wildlife Service, Bird of Conservation Concern No raptor nests were located within the area surveyed surrounding the site. The previous raptor nest documented in the Spring Creek drainage was not found during the November 26, 2013 survey. Noble Energy, Inc. Ramos Laydown Yard Wildlife and Vegetation Impact Analysis Page 7 Olsson Associates Birds of Conservation Concern, Migratory, and Non-Migratory Birds In addition to raptors and grouse, Olsson evaluated the project area for bird species that could potentially occupy habitats surrounding the laydown yard. Birds of Conservation Concern (BCC) have been identified by the USFWS for priority conservation management in an attempt to prevent or remove the need to list additional species under the Endangered Species Act (USFWS 2008). A thorough literature review was conducted to identify the presence/absence of BCC species that have potential to occur in pinyon-juniper woodlands near the site (Andrews & Righter 1992 and Kingery 1998). During the 2009 survey, meadowlarks and western bluebirds were observed. During the 2013 survey, Olsson surveyed the site and surrounding habitat for the presence of any bird species that could potentially occur based on the literature review. It is noted that the survey was conducted outside of the breeding season. Table 5 shows the BCC species for the Southern Rockies/Colorado Plateau that may have potential to occur within the habitats adjacent to the site. The site is an existing well pad and laydown yard and has been cleared of all vegetation; therefore, the site is does not provide wildlife habitat. However, the pinyon-juniper habitat and understory grasses adjacent to the site and surrounding areas do provide potential nesting and foraging habitat for various migratory and non-migratory bird species, depending on the season of the year (Andrews & Righter 1992, Kingery 1998, Righter et al. 2004). Table 5- Status of Birds of Conservation Concern that may occur within the project area. Common Name Scientific Name Status Habitat Description Potential to Occur Brewer’s Sparrow Spizella breweri BCC Sagebrush shrublands; occasionally found in greasewood or other shrublands May occur in sagebrush shrubland habitat near the site. Pinyon Jay Gymnorhinus cyanocephalus BCC Occurs in pinyon/ juniper woodlands May occur in scattered pinyon/ juniper trees northeast and south of the site. Juniper Titmouse Baeolophus ridgwayi BCC Occurs in pinyon/juniper woodlands May occur in scattered pinyon/ juniper trees northeast and south of the site. Cassin’s Finch Carpodacus cassinii BCC Occurs in pinyon/ juniper woodlands, Douglas-fir trees, lodgepole and ponderosa pine forests May occur in scattered pinyon/ juniper trees northeast and south of the site. American Elk and Mule Deer The laydown yard is located within CPW Game Management Unit (GMU) 42. It occurs within CPW-NDIS mapped American Elk (Cervus elaphus) overall range and winter range and in mule deer (Odocoileus hemionus) overall range, winter concentration area, and winter range (Figures 4 and 5). The project area does not occur within CPW-NDIS mapped migration corridors or wildlife habitat linkages for either species. Elk and mule deer may utilize winter range surrounding the site, following the snow line to higher elevations in the spring. Elk are found in semi-open forests or forest edges adjacent to parks, meadows, and alpine tundra and rely primarily on available grasses and browse for food. Mule deer utilize montane forests and pinyon-juniper woodlands with good shrub understory during winter. They rely on sagebrush and shrubs as their primary food source (Fitzgerald et al. 1994). Noble Energy, Inc. Ramos Laydown Yard Wildlife and Vegetation Impact Analysis Page 8 Olsson Associates During the 2009 survey, signs of mule deer were documented (fecal pellets, tracks and 1 shed) within areas surrounding the site. During the 2013 survey, the same was noted in the sagebrush adjacent to the laydown yard, there is no vegetation within the yard footprint. No signs of elk were noted during the survey. It is likely that in addition to migrating elk, the habitat may be utilized on a permanent basis by mule deer. The elements necessary to provide year-round habitat for mule deer, such as forage, cover, and water is present surrounding the project area. The site location does not occur within CPW-NDIS mapped migration corridors or wildlife habitat linkages for either species. Black Bear and Mountain Lion The site occurs with mapped CPW-NDIS black bear (Ursus americanus) and mountain lion (Felis concolor) overall range (Figure 6). Mapped human conflict areas for either species occur >1 mile north and northwest of the site, respectively. Black bear are omnivorous and their diet depends largely on what kinds of food are seasonally available, although their mainstay is vegetation (Fitzgerald et al. 1994). Black bears will eat a diversity of forbs, berries, insects and termites, and may also kill a variety of small mammals including rabbits and rodents (Fitzgerald et al. 1994). No signs of black bear were noted during the survey. Mountain lions have very large territories primarily to search for food and/or new territories. They generally follow deer herds, as this is their primary food source, however, they will prey on elk or moose, ground squirrels, beavers, rabbits, and occasionally livestock. It is possible that the mountain lion may inhabit the general area around the site, but would be transitory as this habitat has high human activity and habitat lacks sufficient cover for hunting (Fitzgerald et al. 1994). The site is more than one mile south of any mapped potential mountain lion conflict areas. No sign of mountain lions were observed during the survey. Small Mammals, Reptiles and Aquatic Species The project area is surrounded by pinyon-juniper, shrubs, and dispersed sage brush habitats. Some of the common small mammals that may occur in the surrounding area include least chipmunk (Tamias minimus), coyote (Canis latrans), gray fox (Urocyon cinereoargenteus), black-tailed jackrabbit (Lepus californicus), mountain cottontail (Sylvilagus nuttallii), striped skunk (Mephitis mephitis), and many rodent species (Mutel and Emerick 1992 and Fitzgerald et al. 1994). The cottontail was documented during the 2009 survey; no small mammals were documented during the 2013 survey. Common reptiles that may utilize the sagebrush and pinyon-juniper habitat near to the site include: collard lizard (Crotaphytus collaris), eastern fence lizard (Sceloporus undulatus), northern side-blotched lizard (Uta stansburiana), northern tree lizard (Urosaurus ornatus), sagebrush lizard (Sceloporus graciosus), short-horned lizard (Phrynosoma douglassii), and western rattlesnake (Crotalus viridis) (Mutel and Emerick 1992). No reptiles were documented during the surveys. No aquatic species would be impacted by the laydown yard facility. The nearest drainage is an unnamed intermittent drainage located approximately <0.10 mile to the north and Spring Creek to the south. Noble Energy, Inc. Ramos Laydown Yard Wildlife and Vegetation Impact Analysis Page 9 Olsson Associates Section 4-203.G(8) (a) Determination of the Long-Term and Short-Term Effect on Flora and Fauna Flora It is not likely that the existing laydown yard would adversely affect federally listed plant species. No additional vegetation removal is associated with the laydown yard, since it is an existing storage facility and within an existing footprint. This site is meant to be permanent, so reclamation will not be addressed in this assessment. Vegetation communities and conditions will not be affected on a long or short term basis and will likely remain in their present condition. The vegetation assessment was conducted in the late fall when most of the plant species had senesced. It is recommended that a follow-up site visit and vegetation assessment occur in the spring in order to identify any early emerging noxious weeds that may be present and to better assess the previously identified noxious weeds establishment. At that time, locations of any present county listed weeds and any rare or endangered plant species found on site and referenced in this report will be recorded with the aid of a handheld global positioning system (GPS) receiver using NAD83/WGS84 map datum, with all coordinate locations based on the Universal Transverse Mercator (UTM) coordinate system in Zone 12. As outlined in Noble’s Noxious Weed Management Plan, the above mentioned weed species should be treated using the best available management tools for each species and situation. Please reference Noble Energy Inc. Noxious Weed Management Plan, located in Appendix B. Fauna Federally Listed Threatened, Endangered, and Candidate Wildlife Species It is not likely that the existing laydown yard would adversely affect federally listed wildlife species. No additional vegetation removal is associated with the laydown yard, since it is an existing storage facility and within an existing footprint. No federally listed species or critical habitat occurs within or near the site. Raptors, Birds of Conservation Concern, Migratory and Non-Migratory birds No additional vegetation removal would be associated with the Ramos Laydown Yard; therefore no suitable raptor, BCC, or other migratory or non-migratory bird species nesting habitat would be affected. Long- or short-term effects related to the site would be minimal due to the area being previously disturbed from activities associated with the laydown yard and the operation and maintenance of the nearby Ramos 1-36 pad. American Elk and Deer Wildlife habitat is not present within the laydown yard. No additional vegetation removal will occur at the site. No impacts to deer or elk would occur as a result. Disturbance associated with human presence and some activities at the site may cause elk and deer to avoid this area; however, this area would remain the same as existing conditions. The Ramos Laydown Yard does not block or impede migration corridors for elk or mule deer. Black Bear and Mountain Lion No additional vegetation removal would occur as a result of this site; therefore, suitable habitat for black bear and mountain lion would remain the same as existing conditions. It is possible that human interactions could occur, but the mapped conflict areas were more than a mile northeast of the site. Noble Energy, Inc. Ramos Laydown Yard Wildlife and Vegetation Impact Analysis Page 10 Olsson Associates Small Mammals and Reptiles and Aquatic species No impacts are anticipated to occur to any small mammals or reptiles, since there will be no additional vegetation removal associated with the site. The laydown yard is absent of any vegetated habitat. Habitat is present adjacent to the site that would offer forage and resting opportunities for small animals. No aquatic species would be impacted by the Ramos Laydown Yard. Section 4-203.G(8) (b) Determination of the Effect on Designated Environmental Resources-Critical Wildlife Habitat The Ramos Laydown Yard is not expected to affect any critical habitat for any wildlife species, as no federally designated critical habitat or species were identified within or near the site. According to the CPW-NDIS GIS data, the laydown yard occurs within overall and winter range for elk and overall range, winter range, and winter concentration area for mule deer. No additional vegetation removal or construction is associated with the site that would further decrease habitat, but could preclude these species from using adjacent habitat as a result of increased human presence. This would not impede any natural migration or movement through the area. Section 4-203.G(8) (c) Impacts on Wildlife and Domestic Animals Impacts to wildlife or domestic animals are expected to be minimal through the creation of hazardous attractions. An existing fence surrounds the site and is used to protect the contents within the laydown yard and to potentially deter domestic animals or wildlife from entering the yard. Since the area is previously disturbed and lacking wildlife habitat, alteration of existing native vegetation has already occurred. The site is currently under a weed management plan implemented by the Noble Energy Inc. The site may disrupt the overall use of the area by wildlife, but due to the relatively small area compared to suitable adjacent habitat, it is not anticipated that the laydown yard would permanently preclude wildlife movement. The inherent risks associated with the use of the laydown yard by birds and small mammals would likely be minimal due to absence of vegetation within the site. However, some bird species or small animals may inhabit or nest on or around equipment. The inherent risks are low. The potential risks can be reduced by closing cavities or covering openings. Section 7-202 Mitigation of Wildlife Habitats Wildlife habitat would not be further affected by the laydown yard because no additional vegetation removal or construction is associated with it. Special requirements or seasonal restrictions would not need to be recommended due to the existing foot print. Ongoing noxious weed management will be required to maintain existing vegetation and wildlife habitat quality, and to control any spread of existing noxious weeds. Noble Energy, Inc.

They possess the ability to dominate plant communities to the extent plant diversity and ecosystem integrity are threatened. Noxious weeds also threaten valuable wildlife habitat, cause economic hardships to agriculture and are a nuisance for recreational activities. Noxious weeds are difficult to eradicate or control because they readily become established in disturbed areas, spread rapidly, possess a unique ability to reproduce profusely, and resist control. In general, noxious weeds are most common in areas where human activity is having or has had the greatest impact on the soil and vegetation and/or where human activities have resulted in the introduction of seed sources. Previously disturbed land, where the plant cover has been removed is susceptible to noxious weed establishment and invasion into adjacent native plant communities. These include roadways, rock or borrow pits, heavily grazed areas, mining, gas and oil drilling areas, and irrigation canals. Species of noxious weeds that are known to occur in the Mesa/Garfield County area in Colorado are listed in Table 1. There are state and federal laws that provide definitions of and guidance for the management of noxious weeds (Colorado Department of Agriculture 2009a,b). The Noxious Weed Management Plan (Plan) provides a process for implementing noxious weed management strategies to be used by Noble Energy Inc. (NEI) during activities in the Piceance Field. The guiding purpose of noxious weed management in this Plan is to preclude the inadvertent introduction, establishment, or proliferation of noxious weed species as a result of NEI development activities. It is the intent of NEI to cooperate with federal and state agencies, local landowners, county weed control agents, and other parties in the management and control of noxious weeds in the area.

The shared goals of: 1) prevention, 2) treatment, 3) monitoring, and 4) cooperation form the framework of this Plan. Each goal is characterized by specific management objectives intended to achieve the goal. Each objective has specific actions that will be implemented by NEI. The following summarizes the goals of this Plan. 1) Prevention Preventive actions include conducting periodic weed surveys and the use of weed-free seed mixtures during reclamation. Weed surveys of the field will be conducted by a local weed expert to identify noxious species on a scheduled basis so that infestations can be treated quickly before they spread. Revegetation activities will be completed in all disturbed areas not required to be vegetation-free. Proper and timely revegetation with desirable species will create less favorable conditions for weed growth and spread. Revegetation will be done with weed-free seed and mulch. Disturbances will minimize spread of weeds by treating them prior to disturbance or avoiding them. 2) Treatment Treatments will be developed using integrated weed management principles for each species and situation. Treatments may include hand pulling, grubbing, mowing, mulching, seeding, burning, herbicide application and soil management, as recommended by NEI’s local weed expert. All treatments will follow the guidelines stipulated in this Plan. Large and/or widespread weed infestations that are beyond the control and influence of NEI will be managed cooperatively with other parties. All treatments will be monitored for effectiveness. 3) Monitoring Monitoring will be conducted on a scheduled basis to detect new infestations, evaluate prevention and/or treatment success, and identify the need for re-treatment. 4) Cooperation NEI will cooperate with the U.S. Bureau of Land Management, Garfield and Mesa Counties and affected landowners to manage noxious weeds in the project area. Piceance Noxious Weed Management Plan January 2010 3-1 3.0 GOALS AND OBJECTIVES Goal 1. Prevention Objective 1: Forestall or hinder the introduction and spread of specific noxious weed species in areas not currently infested. Action: Ensure that disturbed land adjacent to vegetation-free zones is revegetated immediately after disturbance. Although revegetation after ground disturbance is a guiding principle for the management of weeds, NEI requires vegetation-free zones around their well pads and infrastructure for safety reasons. This vegetation-free zone is approximately 250 feet by 300 feet or an estimated 1.6 acres for each well pad. Outside of the vegetation-free zones, NEI will revegetate bare ground regardless of whether noxious weeds are in the local area. Native plant species (or domestic varieties of native species) will be used instead of introduced species for seeding for site protection if the native species can accomplish the site objectives in a reasonable time frame and costs are not excessive. Species and seed mixes that will become established will be used for the reclamation of disturbed ground. Generally, the addition of broadleaf species to seed mixes will be avoided as reseeded areas often require herbicidal treatment of broadleaf weeds in the first year or two, which would also affect all desirable broadleaf species in the treated area. All seed purchased for reclamation purposes will be free of noxious weeds. If hay or straw will be used for mulching, erosion control, rehabilitation, or other uses, it will be free of noxious weeds and their seeds. On national BLM Lands, reclamation will use the approved BLM seed mixes listed in Tables 2-1 through 2-4. Piceance Noxious Weed Management Plan January 2010 3-2 n'='n o ble ' \;:; ene rg y Table 2-1.

Piceance Noxious Weed Management Plan January 2010 3-3 Piceance Noxious Weed Management Plan January 2010 3-4 Objective 2: Prevent the spread or proliferation of existing infestations. Action: Conduct ground disturbing actions consistent with the goals and objectives of this Plan. Where road shoulders or drainage ditches are covered by desirable herbaceous cover, consider leaving it in place rather than clearing it off, if such a practice can be done without causing excessive damage to the road or ground surface or cause significant public safety hazards. Use the following guidelines for existing infestations to be disturbed: (1) if the weed is not in flower, or will not reproduce through damaged plant parts (i.e., vegetatively), proceed with maintenance/road work, (2) if the weed has flowered, either hand pull or cut all tops, bag in a plastic bag (and dispose of appropriately), then proceed with road work; or flag the site for avoidance by the machinery until the infestation is treated; and (3) if the weed is known or suspected to sprout vegetatively from cut parts, flag the site to ensure avoidance by machinery until the weed can be treated by proper means. Goal 2. Treatment Objective 1: Evaluate treatment options for established infestations. Actions: Evaluate each infestation for causal factors and appropriate treatment employing integrated weed management principles. Integrated Weed Management (IWM) is a decision-making process used to select the most appropriate actions from an assortment of options and apply them to each unique situation. IWM Piceance Noxious Weed Management Plan January 2010 3-5 evaluates, integrates, and implements noxious weed management strategies based on predicted ecological, sociological, and economic consequences. IWM includes the use of naturally occurring weed controls including biological diversity, competition, and plant succession. In addition, IWM utilizes various mechanical, biological, cultural and chemical controls, and habitat modification techniques. Objectives will be set for each infestation and will include reasonable and attainable time frames for management. Management objectives may include: control (to prevent reproduction), containment (to prevent off site movement), reduction (to shrink the population in number, density, and/or area covered); and/or eradication (to eliminate permanently from the site). In cases where infestations extend beyond the areas affected by NEI’s activities and/or are contributed to by management of surrounding lands, NEI will coordinate with adjacent landowners to determine the appropriateness and anticipated effectiveness of treatment options. If adjacent lands are not treated, NEI may decline to treat infestations on their areas or to limit their treatments to non- chemical methods or to roadsides only. This will minimize the use of herbicides where results may be poor. The greatest priority for treatment will be placed on species in Garfield and Mesa County classified as Class I. Class II species located outside of public roadways will be given less emphasis for treatment and will not be managed if treatments are predicted to have little effect. Prepare and Implement Treatment Plans Treatment options appropriate for use by NEI are limited to physical, mechanical, cultural, and chemical methods. Specific methods include hand pulling, grubbing, mowing, mulching, burning, herbicide application, and soil management. Appropriate herbicides are a function of the target noxious weed species and are not listed in this Plan. Specific herbicides will be determined in conjunction with the BLM, as appropriate, in order to ensure the best, most current information is applied. Guidelines to be followed for all treatment activities are listed in Appendix C. All treatments will be conducted in a manner consistent with the guidelines and measures in this Plan including all appendices. On BLM land, all treatments will be developed in coordination with the BLM. Piceance Noxious Weed Management Plan January 2010 3-6 Goal 3. Monitoring Objective 1: Implement a sound monitoring program to track prevention and treatment activities and to determine the effectiveness of such practices to meet stated objectives. Actions: Conduct field surveys to detect new infestations and/or changes in existing infestations. Field surveys will be conducted periodically throughout the NEI Piceance field to monitor changes and determine the need for new treatments and re-treatments. Goal 4. Cooperation Objective 1: To coordinate and integrate inventory, prevention and management of noxious weeds with private parties; federal, state and local governments; and other agencies. Actions: Manage established infestations in full coordination with BLM and landowners. Objectives for each established infestation are determined in an integrated manner and are applied through a process based on an assessment of risks, costs/benefits, appropriate strategies and tactics. Determine treatment options cooperatively with affected parties. (See Goals 2 and 4.) Piceance Noxious Weed Management Plan January 2010 4-1 4.0 REFERENCES Garfield County. 2007.

Basic Traffic Analysis Page 1 INTRODUCTION & OBJECTIVE This Basic Traffic Analysis summarizes findings of a traffic impact analysis performed for Noble Energy, Inc and includes two sites, Jones Laydown Yard and Ramos Laydown Yard. The two facilities will be used to store equipment and material associated with natural gas operations. The facilities are currently constructed as well pads. It is expected that the lifespan of the sites will be approximately 30 years. The sites are approximately six (6) travel miles southwest of the West Parachute I-70 interchange near Parachute, CO. The Ramos Laydown Yard is located in the southwest ¼ of Section 1, Township 8 South, Range 96 West of the 6th Principal Meridian in unincorporated Garfield County and encompasses approximately 1.95 acres. The Jones Laydown Yard is located in the southeast ¼ of Section 35, Township 7 South, Range 96 West of the 6th Principal Meridian in unincorporated Garfield County and encompasses approximately 2.42 acres. Both facilities are owned and operated by Noble Energy, Inc. The objective of this analysis is to provide an update to a 2009 study prepared by Environmental & Civil Solutions, LLC for the Ramos site and to jointly review the existing road network and provide traffic projections for the modification of both sites with the additional uses. While these are being permitting under two separate applications, the traffic analysis is being performed for both sites due to their close proximity and thus interactions of site traffic. EXISTING ROAD NETWORK Regional trips to both facilities will use the I-70 West Parachute Interchange southwest of Parachute, Colorado. Vehicles traveling to the sites will drive west along the I-70 frontage road to CR 300 (Stone Quarry Road), then south and east along CR 300 approximately 1.5 miles to CR 306 (Wallace Creek Road). At this intersection, vehicles will turn south along CR 306 and travel southeast approximately 2.5 miles to the existing Ramos well pad. For the Jones site, vehicles will continue along CR 300 for another 0.5 miles past its intersection with CR 306 to CR 304 (Richardson Road) then travel east and then south approximately 1.5 miles to the well pad. Vicinity Maps are included as attachments to this document. The Garfield County Road Inventory Report, 2011 Garfield County HUTF Report, and 2002, Garfield County Road & Bridge county-wide traffic study were all used to identify the roadway geometry and characteristics of the facilities being used by site traffic. That information is shown in Table 1 below. Ramos & Jones Laydown Yards January, 2014 Noble Energy, Inc.

Given the lack of data regarding traffic growth for this area, a conservative growth rate of 3% is assumed. This rate was applied to the existing counts to obtain background traffic for the year 2013. The results are shown in Table 1 below. Table 2: Background Traffic Projections – Logan Wash Storage Area Roadway 2002 Actual 2013 Estimated CR 300 2527 3498 CR 304 - - CR 306 159 220 TRIP GENERATION AND DISTRIBUTION Trip generation is generally determined using rates found in the ITE Trip Generation Manual. Rates from this publication are applied to values related to the size of the proposed site to estimate the trips expected to enter and exit the site. In this case, no rates are provided for facilities similar to these. To estimate trips expected for this site, information was gathered regarding the expected traffic based on the existing operations. According to the 2009 study performed for the Ramos Site, existing vehicle activities during daily operations consist of one (1) pickup truck (two trips per day) with up to 10 pickups per week (20 trips) and an additional one heavy truck (2 trips) per week. Existing traffic data was not available for the Jones site, however it is a similar land use. It is assumed that the trip generation would also be similar. Traffic associated with the additional land use as a storage facility at the Ramos site include ten (10) pickup trucks (20 trips) per day with and additional heavy truck (2 trips) every two weeks to haul pipes to and from the site. Additional trips to the Jones site will include one (1) pickup truck (2 trips) per day and one (1) heavy truck every two months to haul pipes. Each site is already in operation as a well pad. There will be no construction phase associated with the additional land use. Ramos & Jones Laydown Yards January, 2014 Noble Energy, Inc. Basic Traffic Analysis Page 3 Based on the background traffic calculated above, the Ramos and Jones Storage Area facility related traffic will have an average 1% increase on daily traffic activity on CR 300. Background traffic data was not available for CR 304. There will be an average 12% increase in traffic related to site traffic from the Ramos site on CR 306. Table 2 summarizes the expected percentage of trips this facility will generate on county roads. Table 3: Traffic Volume Increases (vpd) Roadway Background Volumes Exist. Ramos Trips Ramos Trips Exist. Jones Trips Jones Trips Total ADT Percent of 2013 ADT CR 300 3498 6 20 6 2 3532 1% CR 304 N/A - - 6 2 - - CR 306 216 6 20 - - 242 12% It should be noted that some of the trips associated with the additional uses will originate from other activities in the immediate area. Therefore, some additional trips are likely accounted for in background traffic projections because the area is currently active and generating trips related to transporting materials in and out of the larger field. The Table 2 above provides a conservative estimate of traffic volume increases, but it is likely that they will be less due to the consolidation of material hauling to the immediate area as related to the storage uses on the existing sites. ROADWAY ANALYSIS Existing Parcels Current land use on the subject parcels is a well pad. Each site is located in an area with existing activities related to natural gas development. There are also some agricultural and rural residential land uses along CR 300 and CR 306. CR 304 serves only natural gas facilities and is not maintained by Garfield County. State Highway Crossings and Access The roadway access to this site does not cross any highway right-of-ways managed by the Colorado Department of Transportation. CR 300 is accessed from the I-70 Frontage Road and from the interstate at the I-70 West Parachute Interchange approximately two miles southwest of Parachute, Colorado. The ramp terminals at this grade-separated interchange are roundabouts. Site distances are adequate in both directions at these ramp terminals. The intersection of CR 300 & I-70 Frontage Road is a two-way stop-controlled intersection with I-70 Frontage Road as the major roadway. Ramos & Jones Laydown Yards January, 2014 Noble Energy, Inc. Basic Traffic Analysis Page 4 Railroad Crossings CR 300 crosses a main railroad line approximately 100 feet south of the intersection of CR 300 & I-70 Frontage Road. Additionally, I-70 Frontage Road crosses the same railroad line approximately 1.6 miles northeast of the De Beque interchange. This rail line is generally used for the transport of freight, coal, and passenger rail traffic. The railroad crossing with CR 300 is an at-grade intersection with flashers and gates. It is expected that trips will use the Parachute South interchange, but in the event that trucks would originate from the Debeque interchange they would need to pass under the rail line while traveling along the I-70 Frontage Road. Clearance at that bridge is 15 feet 2 inches. The roadway access to this site does not cross any other active railroad right-of-ways. Intersection of CR 300 & CR 304 The intersection of CR 300 & CR 304 is a “T” intersection with the CR 304 having a single east leg approach. The angle of the approach is approximately 14 degrees. This angle of approach causes westbound vehicles on CR 304 to look back across their body for approaching vehicles. While it is not anticipated that site traffic, specifically large trucks, would have to negotiate this sharp turn, it does create an undesirable condition for intersection sight distance. A stop sign controls westbound traffic on CR 304 at the intersection of that road with CR 300. However, given the amount of traffic estimated to be generated from the additional use, it is not expected that any existing problems would be exacerbated such that improvements would be required to the intersection as specifically related to this site. Intersection of CR 300 & 306 The intersection of CR 300 & CR 306 is a “T” intersection controlled with a northbound stop sign for CR 306 traffic. For northbound vehicles turning on to CR 300, sight distance looking both east and west at this intersection is adequate. Improvements at this intersection are not anticipated to be needed. CONCLUSIONS Based on the expected trip generation rates discussed above, the increase in average daily traffic is not expected to increase on County Roads such that a modification of the existing access permit would be required. The county roads discussed will see only a minor increase in traffic. The total traffic volumes will remain very low and can be accommodated by the existing roadway. Additionally, the majority of existing traffic on this road is associated with the natural gas industry, particularly along CR 304 which is not maintained by Garfield County.

GENERAL APPROVAL STANDARDS FOR LAND USE CHANGE PERMITS SECTION 7-101. ZONE DISTRICT USE RESTRICTIONS The subject property is located in the Rural (R) zone district of Garfield County in the Northeast ¼ of the Southwest ¼ of Section 1, Township 8 South, Range 96 West of the 6th PM. The proposed use is considered a Storage use according to Table 3-403: Use Table of the Garfield County Unified Land Use and Development Code. This use requires a Limited Impact Review (LIR) to obtain a Land Use Change Permit (LUCP). SECTION 7-102. COMPREHENSIVE PLAN AND INTERGOVERNMENTAL AGREEMENTS The Ramos Laydown Yard generally conforms to the Garfield County Comprehensive Plan. The site is designated in the Garfield County Comprehensive Plan 2030 as a Residential Medium High (RMH) area with a residential density of 2 to 6 acres per dwelling unit. According to the Comprehensive Plan, facilities that are appurtenances to oil/ gas development activities (compressors, etc.) are considered appropriate in all land uses so long as they meet the respective mitigation requirements of the ULUR to maintain compatibility with surrounding land uses. The existing use is not within an area governed by an intergovernmental agreement. SECTION 7-103. COMPATIBILITY The proposed site is located within the boundaries of a 40 acre property. The storage use would be limited to a 92,137 square foot or 2.11 acre area. Rural residential, natural gas development and agriculture are the predominate uses on the subject parcel and surrounding properties. The closest residential uses to the proposed storage yard are approximately 1500 feet to the west (Nauroth), 1,000 feet to the south (Murray) and 1,000 feet to the east (Ramos). The residential use to the east is on the subject parcel. The parcel to the north only contains oil and gas production facilities. The proposed use is intended to provide a centralized and convenient storage location for the natural gas operations in the immediate area. This proposed use is compatible with and supportive of the adjacent uses. Noble Energy, Inc Ramos Laydown Yard Standards Analysis Page 2 SECTION 7-104. SOURCE OF WATER A source of potable water will not be required for workers utilizing the site. This facility is not manned on a regular basis and does not require a water distribution and wastewater system to properly function. Workers will provide their own potable water in their trucks. Noble will provide personnel bottled or potable water at their field office. A source of water is not required for the operation of the facility. The site will be used as a storage facility. Water will not be required for the operation of sanitary facilities. Portable toilets will be used and all wastes will be hauled to a licensed treatment facility. Water will not be required for landscaping. No landscaping is proposed at this site. SECTION 7-105. CENTRAL WATER DISTRIBUTION AND WASTEWATER SYSTEMS A. Water Distribution System As stated above, the proposed facility will not require a source of water or a central water distribution system. B. Wastewater Systems As stated above, the proposed facility will not require a centralized wastewater system. Portable toilets will be used and wastes will be hauled to a license disposal facility. SECTION 7-106. PUBLIC UTILITIES The facility will not require public utilities in order to operate. SECTION 7-107. ACCESS AND ROADWAYS A. Access to Public Right of Way No new roads are proposed to accommodate the additional storage use. Access to the subject property is from County Road (CR) 30 (Wallace Creek Road) via a private driveway. The existing roadway and access are adequate for the anticipated low traffic volumes. Dust from the private driveway will be mitigated as appropriate. B. Safe Access The access driveway meets the Primitive Roadway / Driveway standards of Table 7-107 of the Land Use and Development Code. The county road system and private driveway provides safe access to the facility. C. Adequate Capacity The proposed facility will generate little traffic and the current road system has adequate capacity to support the proposal. See Traffic Analysis included with this application for additional details. D. Road Dedications No new public roads are being built or dedicated as part of this project. Noble Energy, Inc Ramos Laydown Yard Standards Analysis Page 3 E. Impacts Mitigated County roads will experience minor impacts from this project. The proposed storage use may actually reduce traffic impacts by limiting the need to haul equipment in and out of the area when it is needed. See the Traffic Analysis for further information. F. Design Standards As stated above, no new roads are being built as part of this project. SECTION 7-108. USE OF LAND SUBJECT TO NATURAL HAZARDS According to the Natural and Geological Hazard Assessment Report the project area is not subject to rock fall, snow slides, radiation, flooding or high water hazards. Since the last period of glaciation the area has been subject to mudflows and landslides. Given the proposed storage use and the typical period between these occurrences, these events should not present a significant hazard. SECTION 7-109. FIRE PROTECTION Noble makes their Emergency Response Plan available to the appropriate fire protection district. If requested, Noble will orientate the appropriate fire protection district regarding this facility. DIVISION 2. GENERAL RESOURCE PROTECTION STANDARDS SECTION 7-201. AGRICULTURAL LANDS A.

Domestic Animal Controls Dogs and other domestic animals will not be permitted on the property or allowed to interfere with livestock. C. Fences The site will be fenced. D. Roads No new roads will be constructed to access this facility, and the existing road will be maintained. E. Irrigation Ditches The proposed use will not impact irrigation ditches. Noble Energy, Inc Ramos Laydown Yard Standards Analysis Page 4 SECTION 7-202. WILDLIFE HABITAT AREAS A. Buffers Visual or sound buffers are not necessary to screen activity areas from habitat areas. According to the Wildlife Assessment performed by Olsson Associates, it is not likely that the proposed laydown yard would adversely affect federally listed wildlife species. No additional vegetation removal is associated with the laydown yard, since it was previously disturbed. Olsson Associates surveyed the project site for the potential habitat for the greater sage grouse. They found the area to be poor habitat for the greater sage grouse. The greater sage grouse inhabits vast, continuous sagebrush communities. Sagebrush is present in the vicinity of the site; however, this habitat is limited in the area and highly fragmented. Additionally, the amount of existing disturbance and agricultural land would preclude sage grouse use of the area. B. Locational Controls of Land Disturbance The project area is currently disturbed. No additional wildlife habitat disturbance will occur. According to the Biological Assessment the site is not within CPW-NDIS mapped migration corridor for elk or deer. The project area does not provide wildlife habitat linkages for either species. C. Preservation of Native Vegetation The site will be reclaimed after the facility is no longer utilized and will be revegetated with native plant species. Noxious weeds will be controlled during the life of the facility and during the re-establishment of native plants. D. Habitat Compensation No critical wildlife habitat will be disturbed at this site. E. Domestic Animal Controls Domestic animals will not be kept on the site. SECTION 7-203. PROTECTION OF WATERBODIES A. Minimum Setback The proposed site is located approximately 1,400 feet north of Spring Creek. The project area will be more than 35 feet from the Typical and Ordinary High Water elevation of this stream. B. Structures Permitted in Setback There will not be any structures located in this setback area. C. Structures and Activity Prohibited in Setback There will not be any structures or activities located in the buffer zone. Noble Energy, Inc Ramos Laydown Yard Standards Analysis Page 5 D. Compliance with State and Federal Laws The facility will comply with all applicable state and federal laws. SECTION 7-204. DRAINAGE AND EROSION The site is an existing disturbed surface area. Minor additional surface disturbance is planned. BMPs will be used to protect water bodies from stormwater runoff during the operation of this facility. This facility is more than 100 feet from a water body, and it does not create more than 10,000 square feet of impervious area. SECTION 7-205. ENVIRONMENTAL QUALITY A. Air Quality This facility will not cause air quality to be reduced below acceptable levels established by the Colorado Air Pollution Control Division and will comply with appropriate Colorado air emissions regulations as applicable. The equipment and materials proposed to be stored on site will not require an APEN. B. Water Quality This facility will be operated in compliance with all applicable State and Federal hazardous material regulations. Implementation and adherence to Noble’s Stormwater Management Plan (SWMP) BMPs and Spill Prevention Control and Countermeasures Plan (SPCC) will assure that water quality is protected. There will be no hazardous materials stored at this proposed site. SECTION 7-206. WILDFIRE HAZARDS A. Location Restrictions The site is in a low wildfire hazard area according to the Garfield County on-line GIS map resources. F. Development Does Not Increase Potential Hazard The facility will not increase the potential intensity or duration of a wildfire, or adversely affect wildfire behavior or fuel composition. G. Roof Materials and Design No structures are being proposed. This standard is not applicable. SECTION 7-207. NATURAL AND GEOLOGIC HAZARDS A Natural and Geological Hazard Assessment Report is included with this application under a separate tab. A. Utilities Installations of buried utilities are not expected to be associated with the construction of the proposed laydown yard. Therefore, geologic hazards associated with trenching or excavation Noble Energy, Inc Ramos Laydown Yard Standards Analysis Page 6 for the placement of buried utilities is not expected to affect the proposed project. The laydown yard will be used to store sections of pipe and equipment above grade for use elsewhere in the area and region. B. Development in Avalanche Hazard Areas The site is not located in a known avalanche hazard area. Winters are cold in the mountainous areas of Garfield County, and valleys are colder than the lower parts of adjacent mountains due to cold air drainage. Average seasonal snowfall in Garfield County is 50 inches. The greatest snow depth at any one time during the period of record from 1951 to 1974 was 29 inches recorded at Rifle, Colorado approximately 30 miles to the east of the proposed site. Much of the Rifle area is at a higher elevation than the town of Rifle and is somewhat cooler and receives more precipitation. Avalanches are not expected to affect the proposed laydown yard, since it is located at elevations between 6000 feet and 8000 feet. C. Development in Landslide Hazard Areas Landslides in Colorado in the western part of the state are typically associated with areas of significant slopes where landslides are natural and ongoing events. Landslides can be triggered by human activities disrupting the land and periods of precipitation which increase the chances of landslide occurrence. According to the Garfield County GIS Surficial Geology map, the areas to the southwest of the town of Parachute and on the south side of the Colorado River have not been mapped for landslide potential. According to the Geologic map of Surficial Deposits in the Grand and Battlement Mesas Area, Delta, Mesa, and Garfield Counties, Colorado, the site is located in an area of Pleistocene age pediment gravels estimated to have been deposited pre-Bull Lake age glaciation. The nearest mapped landslide deposits are located to the north in Township 7 South, Range 96 West. D. Development in Rockfall Hazard Areas The site is not located within an area that has been mapped as having rockfall or potential for rockfall. Potential rockfall areas are present to the west along Log Mesa where piedmont gravels lie along steep slopes in the southwest part of Section 12. E. Development in Alluvial Fan Hazard Area The site is located in an area of pediment gravel. Areas closer to the Colorado River near Township 7 South, Range 96 West, have been mapped as alluvial fans, alluvial terrace and fan gravel deposits. Alluvial fan areas are located along the flanks of Flatiron Mesa and Grass Mesa, and pediment gravels along the Wallace Creek and Pete and Bill Creek drainages. These alluvial sediments were transported down from higher elevations on Battlement Mesa and prograded out over outcrops of the Wasatch Formation pediment. Outwash gravels and worked glacial alluvium deposited by retreating glaciers are present in the major stream valleys in the area. The present streams have cut narrow valleys into these alluvial fill and fan deposits. Poorly sorted alluvial fan deposits are present along the sides of tributaries where they empty into the Colorado River. Noble Energy, Inc Ramos Laydown Yard Standards Analysis Page 7 F. Slope Development According to the Garfield County Slope Hazard Study Areas 1, 2, & 3 map, the area south of the Colorado River and the towns of Parachute and Battlement Mesa, Colorado, has not been mapped as being in an area of major slope hazards. The slope hazard map recommends that site specific investigations should be conducted to assess active landslide areas. G. Development on Corrosive or Expansive Soils and Rock The proposed laydown yard is not located in an area known to have corrosive or expansive soil or rock types based on a review of the site geology. No permanent structures are to be built. H. Development in Mudflow Areas There are no mapped mudflow or debris fan areas in the immediate vicinity of the proposed laydown yard. I. Development Over Faults Based on a review of Colorado’s Earthquake and Fault Map major faults are not known in the project area. Faults have not been mapped at the surface in the project area according to USGS Professional Paper 617, Plate 1 or on the Geologic Map of the Housetop Mountain Quadrangle. SECTION 7-208. RECLAMATION After the completion of Noble’s natural gas production in the area, the facility will be decommissioned and reclaimed in accordance with the reclamation plan provided in the Supplemental Materials.

Connor Consulting, Inc Page 2–1 Section 2.1 Purpose This company Incident Management Plan (IMP) has been prepared for all domestic operations carried out by Noble Energy. It defines the organizational structure, the communication channels, and the main actions to be taken by the designated company personnel and resources engaged in response to emergency situations. This plan provides the holder with the necessary information to manage a response to an incident that may occur while assigned to Noble Energy’s Incident Management Team (IMT). The plan provides guidance for responding to any type of exploration, production or pipeline incident (spill, medical, well control, explosion/fire, etc.) that may occur on a facility operated by Noble. The plan will provide the holder with a road map to guide them through the complexities of notifications, agency interactions, important contacts, and procedures necessary for a successful response operation. The protection of life, environment and property will be the focus of priorities in operational scenarios whether routine or emergency. This plan is a living document, and is intended to be linked to existing Risk Management, Emergency Response, Inclement Weather, and Environmental plans associated with specific projects and facilities comprehensive operations reviews. Improved procedures from these sources will be incorporated herein as appropriate. Suggestions for improvement may be submitted to Noble Energy’s HSE Manager who will ensure consideration of the document’s amendment as appropriate. This plan will be revised as necessary to cover future company-operated activities. Objectives & Expectations • Emergency management plans are based on the risks that potentially impact the business. These plans are documented, accessible, clearly communicated and align to the Noble Energy’s incident management system. • Equipment, facilities and personnel needed for emergency response are identified, tested and available. • Personnel are trained and understand emergency plans, their roles and responsibilities, and the use of crisis management tools and resources. • Drills and exercises are conducted to assess and improve emergency response/ crisis management capabilities, including liaison with and involvement of external organizations. • Periodic updates of plans and training are used to incorporate lessons learned from previous incidents and exercises.

Connor Consulting, Inc Page 3–1 Section 3.1 Goal of Incident Management Response Operations The goal of incident management is the restoration of normal operations while minimizing impacts to people, the environmental, and property. To achieve this goal, Noble Energy incident and crisis response personnel, at all levels, must be able to move from a reactive to a proactive mode of operations by establishing and maintaining command and control over the situation. For incident response operations, these are procedures that allow incident response personnel to rapidly and efficiently determine and communicate effectively about the problem, its potential and what is being done to address the problem and its potential. During crisis response operations, corporate crisis response personnel should address this objective by analyzing the information generated by incident response personnel and determining the implications of the incident on the Company. The analysis should focus on public health and safety, environmental and community protection, external affairs, human resources, legal, business and financial issues that are attendant to, but separate from those more properly addressed by emergency response personnel. Incident vs. Crisis Response Operations Incidents are any events or situations that require the conduct of emergency and/or crisis response operations by incident response personnel. Incidents generally happen unexpectedly and interrupt or interfere with normal operations. Most incidents generate emergency response operations directed at protecting human health and safety, maximizing protection of the environment and minimizing damage to property. Incidents also have the potential to precipitate crises. Crises arise when incidents impact, or have the potential to impact Noble’s visibility, operability, credibility, pose or have the potential to pose, a significant environmental, economical or legal liability.

Connor Consulting, Inc Page 3–2 Section 3.2 Levels of Response Not all incidents require full implementation of the Incident Management Plan or activation of the entire Incident Management Team. For all emergency scenarios identified, three tiers (levels) of emergencies have been defined in relation to the magnitude, the provision of resources for the response, and the level of Noble Energy’s involvement. They range from a localized emergency that can be dealt with by on-site facility personnel to major incidents which may require the intervention of Noble Energy Corporate resources. Figure 3-1 on page 3-3 shows the decision tree for the emergency classification; Table 3-1 on page 3-4 further describes the types of incidents and the level of response activation for each Tier.

Connor Consulting, Inc Page 3–6 Section 3.4 Response Management Teams Noble Energy utilizes a tiered command system for emergency response. Response is managed through a multi-tiered response system, starting with the Tactical Response Team at the facility, supported by the Business Unit and Regional offices, which in turn are supported by a Corporate Incident Management Team out of the Houston office. Section 1.2 depicts the combined Tactical and Incident Management Team. Noble’s multi-tier response system is designed to handle worst-case situations. Standard processes and well-trained people enable us to mobilize quickly and start managing priorities. Thereafter, the response organization can be modified to suit the particular incident. Business Unit and Regional managers are accountable for ensuring that plans and effective resources are in place throughout their organization to mobilize the first two tiers of response. Since they are unlikely to have the personnel resources to handle a worst-case incident, they may require assistance from other parts of the organization. Noble Energy’s organizational and management approach to incident response and crisis management operations is accomplished through the Incident Command System (ICS), ICS has been adopted by Noble because: • It is mandated by the National Incident Management System (NIMS), the response management system adopted by federal, state, and local government response organizations, • It functionally meets the goals and requirements of Noble’s EH&S policies and standard for environmental excellence and • It ensures ongoing performance capabilities within local and regional legislation. The ICS organizational principles that have been adopted by this IMS are: • The ability to address all risks and hazards, • The ability to mobilize an organization that is functional (i.e., one that is organized to perform the tactical and strategic work necessary to address the incident and to protect people, the environment and property), • The ability to activate and deactivate the functional organization in a modular fashion, • The maintenance of a hierarchical structure that has a clear Chain-of-Command and well defined reporting relationships, and • The ability to establish and maintain a Unified Command with involved incident response organizations. SECTION 3 PICEANCE, CO - DISTRICT #14 INCIDENT MANAGEMENT PLAN Uncontrolled copy—Valid only at 9/23/2008 12:12 PM J. Connor Consulting, Inc Page 3–7 The ICS management principles that have been adopted by Noble’s IMT are: • The use of common terminology, • The maintenance of a manageable Span-of-Control, • The preparation of Incident Action Plans, • The use of comprehensive resource management techniques, • The pre-designation of incident facilities and • The establishment of integrated communications. Response Management Teams Tactical Response Teams Tactical Response Teams (TRT) are the response teams at each field facility that are responsible for implementing the necessary local actions to respond to and manage the incident. The responding TRT handles all tactical response operations, including: • Ensuring that tactical response operations are carried out in a safe, well- organized, and effective fashion, • Sizing up the incident to identify the problems that need to be addressed by tactical response personnel, • Developing solutions to the problems and breaking the work that needs to be done down into manageable tasks to achieve site control, ensure site safety, control the source of the incident, and protect people, the environment, and property, • Securing and assigning necessary tactical response resources, • Supporting tactical response operations, • Continuously assessing the incident to determine the adequacy of tactical response operations and the need for assistance from the IMT and • Interacting, as appropriate, with IMT personnel, government agency officials, and other involved or interested parties. Tactical Response Teams are capable of handling most incidents that occur at Noble’s facilities and in the company's operations. However, the potential exists for incidents that require a response capability beyond that provided by the TRTs. If and when such incidents occur, the IMT would be activated and would build on the TRT organizational structure. SECTION 3 PICEANCE, CO - DISTRICT #14 INCIDENT MANAGEMENT PLAN Uncontrolled copy—Valid only at 9/23/2008 12:12 PM J. Connor Consulting, Inc Page 3–8 Incident Management Team The primary role of the Incident Management Team is to provide strategic direction to incident response operations, support tactical responders, address tactical and/or crisis issues and concerns best handled at the IMT level, and manage the overall impact of the incident on the Company. The functions carried out by the IMT include: • Sizing up the incident and the nature and status of tactical response operations • Developing strategic objectives and response priorities • Gathering information on the nature and location of tactical response operations and the resources being used to carry out the operations • Securing the resources necessary to support tactical response operations • Working with the TRT(s) to develop Incident Action Plans describing field assignments for the next operational period • Securing the resources necessary to implement the General Plan • Instituting and enforcing appropriate financial controls • Continuously assessing incident potential to determine an incident’s capacity to grow into a crisis situation One of the factors that would lead to a decision to activate the IMT would be if the incident is severe enough to trigger the direct involvement of one or more government agencies in emergency response operations. When this occurs, the IMT would take the lead in interacting with agency personnel, which may include establishing a Unified Command Structure and integrating agency response personnel, as appropriate, into the Noble Energy incident response organization.

Dial-In Number: 877-394-0659 International Dial-In Number: 602-462-9833 Conference ID: 218062 Upon notification of a Tier 2 incident, the HS&E Manager (or his/her designee) will activate the conference bridge to be used by all company responders. The first responder to the incident site should remain on the Conference Bridge if reception and safety factors allow. A Documentation Leader will be assigned to keep a log of all significant events and phone calls made. Once the Conference Bridge has been established, the Incident Commander will set the meeting schedule for responders to call in to the Conference Bridge. The Conference Bridge will remain active until the Incident Commander decides to end the call.

SECTION 5 PICEANCE, CO - DISTRICT #14 INCIDENT MANAGEMENT PLAN Uncontrolled copy—Valid only at 9/23/2008 12:13 PM J. Connor Consulting, Inc Page 5–2 Section 5.2 Organizational Principles of the ICS Noble Energy, Inc.’s organizational and management approach to incident response and crisis management operations is accomplished through the Incident Management System (IMS). Based on the Incident Command System (ICS), this Incident Management System has been adopted by Noble Energy, Inc. because: • It is compliant with the National Incident Management System (NIMS), the response management system adopted by federal, state, and local government response organizations, • It functionally meets the goals and requirements of Noble Energy, Inc.’s EH&S policies and standard for environmental excellence and • It ensures ongoing performance capabilities within local and regional legislation. The Incident Command System organizational principles that have been adopted by this Incident Management System are: • The ability to address all risks and hazards, • The ability to mobilize an organization that is functional (i.e., one that is organized to perform the tactical and strategic work necessary to address the incident and to protect people, the environment and property), • The ability to activate and deactivate the functional organization in a modular fashion, • The maintenance of a hierarchical structure that has a clear Chain-of-Command and well defined reporting relationships, and • The ability to establish and maintain a Unified Command with involved incident response organizations. The Incident Command System management principles that have been adopted by Noble Energy, Inc.’s Incident Management System are: • The use of common terminology, • The maintenance of a manageable Span-of-Control, • The preparation of Incident Action Plans, • The use of comprehensive resource management techniques, • The pre-designation of incident facilities and • The establishment of integrated communications. SECTION 5 PICEANCE, CO - DISTRICT #14 INCIDENT MANAGEMENT PLAN Uncontrolled copy—Valid only at 9/23/2008 12:13 PM J. Connor Consulting, Inc Page 5–3 Section 5.3 Incident Command System Functionality The primary organizational principle of ICS is that response teams should be functional in nature (i.e., they should be organized to carry out the work that must be performed to protect people, property, and the environment). Five major functions have been identified that serve as the foundation of the Incident Management Organization: Command, Operations, Planning, Logistics, and Finance. In a small incident, a single person can address all five functions. The Incident Management Team is multi-functional and covers areas including Public Affairs, Community Liaison, Legal, Human Resources, ES&H, Operations, Planning, Logistics, and Finance. Incident Management organizations are modular in nature; that is, they are activated and de-activated in a modular fashion. When an incident occurs, the Incident Management Team’s Incident Commander activates only the functions needed to support tactical response operations; and deactivates the functions as soon as they are no longer needed. In addition, Incident Management organizations are hierarchical in nature. There is a clear chain-of-command to facilitate communications and the decision-making process. Finally, the structure of Incident Management organizations must remain flexible. SECTION 5 PICEANCE, CO - DISTRICT #14 INCIDENT MANAGEMENT PLAN Uncontrolled copy—Valid only at 9/23/2008 12:13 PM J. Connor Consulting, Inc Page 5–4 Section 5.4 Common Terminology An Incident Management Team is made up of individuals who may not work together except during emergency response operations. When they come together, the use of common terminology is viewed as an essential element in team building and communications, both internally and with response personnel from government organizations and contractors. The Incident Command System (ICS) promotes the use of common terminology, and has an associated glossary of terms that help bring consistency to positions titles, the description of resources and how they can be organized, the types and names of incident facilities, and a number of other subjects SECTION 5 PICEANCE, CO - DISTRICT #14 INCIDENT MANAGEMENT PLAN Uncontrolled copy—Valid only at 9/23/2008 12:13 PM J. Connor Consulting, Inc Page 5–5 Section 5.5 Manageable Span-of-Control Manageable span-of-control is the most fundamentally important principle of the Incident Command System (ICS). It applies to the management of individual responsibilities and allocation of any required response resources. The objective is to limit the number of responsibilities being handled by, and the number of resources reporting directly to, an individual. Based on experience, the number is thought to range from three to seven, with five being considered an optimum number. When span-of-control problems arise, they can be addressed by expanding the organization in a modular fashion. This can be accomplished in a variety of ways. When the number of single resources exceed a person’s span-of-control, they can be grouped together into Task Forces. When the number of Task Forces exceeds a person’s span-of-control, they can be grouped into Divisions (Task Forces are assigned to a specific geographic area) or Groups (i.e., when the Task Forces are assigned to functions that cross the geographic boundaries of Divisions). When the number of Divisions and/or Groups exceed a person’s span-of-control, the Divisions and/or Groups can be divided into Branches. SECTION 5 PICEANCE, CO - DISTRICT #14 INCIDENT MANAGEMENT PLAN Uncontrolled copy—Valid only at 9/23/2008 12:13 PM J. Connor Consulting, Inc Page 5–6 Section 5.6 Objective-Driven Response The Incident Command System (ICS) promotes a structured pattern of thought for personnel managing response operations. It stresses the importance of establishing and addressing objectives in the formulation and execution of plans of action. The Incident Commander’s reports should engage in a continuous assessment process designed to: • Determine what must be done, if anything, to stabilize the incident, and to protect people, property, and the environment; and, • Evaluate the effectiveness of ongoing tactical response operations The Incident Management Team process should result in the formulation of an overall strategy that defines what tactical responders will be asked to achieve, and tactics that define how the strategy will be implemented. Once the tactics are defined, the work to be done to carry out the tactics should be broken down into manageable tasks. Each task should be assigned to a Task Leader, and available tactical response resources should be assigned to the tasks. Information on the overall strategy, tactics, and tasks should be forwarded to the Incident Management Team (IMT) where it should serve as the basis for the formulation of Strategic Response Objectives. SECTION 5 PICEANCE, CO - DISTRICT #14 INCIDENT MANAGEMENT PLAN Uncontrolled copy—Valid only at 9/23/2008 12:13 PM J. Connor Consulting, Inc Page 5–7 Section 5.7 Incident Action Plans The structure pattern in Section 5.6, Objective-Driven Response, leads to the formulation of field assignments. Field assignments describe exactly what is going to be done to address response objectives, by whom, how, where, when and with what resources. Field assignments, in turn, serve as the nucleus of a document referred to as an Incident Action Plan (IAP). An Incident Action Plan generally is prepared for a period of time referred to as the next Operational Period. In addition to field assignments, an Incident Action Plan may contain: • overall response objectives • an organizational assignment list • a communication plan • an emergency medical plan • an air operations plan • environmental sensitivities to be observed by field operations • other documents The actual contents of an Incident Action Plan vary depending on the nature and demands of response operations. When two or more response organizations are responding to an incident, it is important that the organizations work together to formulate one consolidated Incident Action Plan that fully addresses mutually agreed- upon objectives. SECTION 5 PICEANCE, CO - DISTRICT #14 INCIDENT MANAGEMENT PLAN Uncontrolled copy—Valid only at 9/23/2008 12:13 PM J. Connor Consulting, Inc Page 5–8 Section 5.8 Planning Cycle In addition to an organizational structure, the Incident Command System is a management tool built around a schedule of tasks, planning and meetings. Operational Periods are established, usually from 12 to 24 hours, and during each period a series of meetings occur, goals are established, and plans for the next Operational Period are developed. See Figure 3.1 on page 3-3 for a list and description of the meeting cycle, which should be repeated during each Operational Period. The key goals of the Incident Command System (ICS) are to proactively manage the incident by preparing an Incident Action Plan for the next Operational Period, dispatch resources in a precise and controlled manner, and monitor the response, making adjustments as circumstances change.

Ramos Laydown Yard OA Project No. 013-2329-100 760 Horizon Drive, Suite 102 TEL 970.263.7800 Grand Junction, CO 81506 FAX 970.263.7456 www.olssonassociates.com ACCESS ROAD ASSESSMENT NOBLE ENERGY, INC RAMOS LAYDOWN YARD The Ramos Driveway (Access Road) begins where it turns off of County Road (CR) 306 (Wallace Creek Road) in the NE ¼ of the SW ¼ of Section 1, Township 8 South, Range 96 West of the 6th P.M. and terminates at the Ramos Laydown Yard (laydown yard). This access road is approximately 522 feet from CR 306 to the laydown yard. Statement of Adequacy This access road crosses an existing COGCC approved well pad and is typical of roads providing access to natural gas production facilities in Garfield County. The roadway is adequate for the intended use. Geometry of Road The following table compares this access road to the Garfield County Roadway Standards found in Table 7-107 of the Land Use and Development Code for Primitive Roadways and Driveways. Table 7-107: Roadway Standards Design Standards Primitive/ Driveway Ramos Access Road Design Capacity (ADT) 0-20 ≤20 ADT Minimum ROW Width (Feet) 15 to 30 30 ft Lane Width (Feet) Single Lane 12 Single Lane 16 to 30 ft Shoulder Width (Feet) 0 0 to 4.5 ft Ditch Width (Feet) 3 0 Cross Slope 2% 0.1 to 2.5% Shoulder Slope n/a n/a Design Speed n/a n/a Minimum Radius (Feet) 40 100 to 350 ft Maximum % Grade 12% 0.1 to 10.3% Surface Native Material Native Material and Gravel Cross slope is 2 percent or less on most of the access road, except for a short portion crossing the well pad where the cross slope is 2.5 percent. Horizontal curve radii on this access road exceed the 40 foot minimum. Maximum grade is 10.3 percent or less. The access road easement is 30 feet wide. The actual driving surface is 16 to 31 feet in width, and two opposing vehicles can pass each other on the access. Because this access crosses an existing well pad location, no ditches are located along the driveway. The Surface Use Lease Ramos Laydown Yard Noble Energy, Inc. Access Road Assessment Page 2 Agreement between the landowner and Noble dictates that the driveway be constructed with 3 inches of 3-inch road base and capped by 3 inches of ¾-inch road base. The road is constructed of native material and road base according to the code standard. See the drawing accompanying this report for details related to the access road. Safety/Structural Issues No obvious safety or structural issues were observed on the date of the field observation, November 21, 2013. Maintenance The access road for this facility will be maintained using equipment (such as dozers, heavy trucks, backhoes, etc.) available to Noble in the field of operations. The road will be graded and augmented with road base on a monthly basis (or more frequently in order to assure access to the facility). The Access Easement Agreement between the property owners and Noble outlines maintenance requirements such as grading and surface, protection of water sources and conveyance structures, and dust mitigation via the use of magnesium chloride. Travel Demand Average Daily Traffic (ADT) is expected to be equal to or less than twenty (20) as shown in the Basic Traffic Study prepared by Olsson Associates, dated January 2014, included with this submittal. This roadway is being assessed according to the standards for a Primitive Roadway/Driveway. Traffic associated with the additional land use as a storage facility at the site include 10 pickup trucks (20 trips) per day with an additional heavy truck (2 trips) every two weeks to haul pipes to and from the site. The adjacent site is currently in operation as a well pad. There will be no construction phase associated with the additional land use or with additional drilling. Other Evidence of Compliance Section 7-107.A Ac cess to Public Right-of-Way Access is granted from County Road 306 to the project site as part of the Surface Lease Agreement between Stella and Robert Ramos and Noble Energy, Inc, Reception number 732812, and the Access Easement Agreement between Robert and Stella Ramos and Noble Energy, Inc., Reception number 754936 (see Deeds section of this submittal). Driveway permit 04-85 applies to this access road. Section 7-107.B Safe Access Access to the site is consistent with other similar uses. Section 7-107.C Adequate Capacity Traffic congestion is not anticipated as a result of the proposed laydown yard. Section 7-107.D Road Dedications The access road is a private road. No rights-of-way will be dedicated to the public. Section 7-107.E Impacts Mitigated Based on the expected trip generation rates discussed in the Basic Traffic Study, the increase in average daily traffic is not expected to increase on County Roads such that a modification of the Ramos Laydown Yard Noble Energy, Inc. Access Road Assessment Page 3 existing access permit would be required. The total traffic volumes will remain very low and are anticipated to be accommodated by the existing roadway. Additionally, the majority of existing traffic on this road is associated with the natural gas industry. Conclusions The Ramos Laydown Yard Access Road deviates from the Design Standards in Table 7-107 for ditch width and cross slope. The intent of the ditch width and cross slope is to facilitate proper drainage off the roadway while allowing vehicles to access the site. The cross slope varies due to maintenance practices and the natural topography of the area. The surface is graveled and the drainage and access is not compromised by the varied cross slope. Full compliance with the cross slope standard would require that the road be regraded, causing additional disturbance. There are no ditches along this access road, because it crosses an existing well pad location. Adding ditches to the road through the well pad would put traffic barriers to the activities on the well pad. The road functions adequately as built and is typical of existing roads providing access to natural gas production in Garfield County. Wyatt E.

This letter serves as Noble Energy’s response to your March 5, 2014 technical completeness letter. Legal Use, Grading and Drainage, Reclamation 1. The application states that the proposed storage facility will be on a COGCC approved well pad. Although it is understood that there are no wells on the well pad currently, the site has been graded and impacted, presumably, in accordance with this APD. As a result, per Section 4-201(8), it will be necessary to review the APD as well as any reclamation and revegetation plans associated with the well pad in tandem with this Land Use Change Permit. This information is important because it impacts the drainage, grading and storm water management plans. Noble Response: This site was intended to be permitted for drilling. It was never permitted with the COGCC for drilling and will not be. The construction of the laydown yard does not require any COGCC permitting. 2. The submitted Grading and Drainage Plan indicates that the site was "previously designed and constructed under a separate cover". It is important to understand this "separate cover'', presumably a COGCC approved APD, to demonstrate compliance with Section 7-204 of the LUDC. Specifically, stating that the "Drainage design is not included as the site appears to have been designed under separate cover'' for Section 4- 203(E}(l4) is not an adequate response without documentation of the "separate cover'' to demonstrate compliance. Should the "separate cover'' documentation not demonstrate compliance, it is the responsibility of the applicant to demonstrate compliance regardless of previous disturbance or grading to the site. Noble Energy, Inc. Limited Impact Review Land Use Change Permit – Ramos Laydown Yard – Storage Garfield County File Number LIPA-7825 NTC Response Page 2 3. Noble Response: Noble has previously submitted information and photographs prepared by a PE indicating that there are no drainage concerns for this existing stabilized site. No additional surface disturbance is anticipated at this site thus there will be no resultant in changes to drainage patterns. Gathering of survey information and preparation of an expanded Grading and Drainage assessment by the PE has been delayed due to weather restrictions and time schedules. It will take at a month to complete the final Grading and Drainage Plan. A waiver request for the submittal requirement is included in this response. If Garfield County deems the waiver request to be inappropriate, an alternative would be to assign a Condition of Approval for the submittal of the expanded Grading and Drainage Plan when it is completed. 4. Although it is understood that there are no current plans to drill on this approved and graded well pad, as the storage is expected to be utilized for up to 30 years, an explanation on how the site is anticipated to transition from storage to a well pad should drilling take place within the lifespan of the storage site is also necessary for a complete review. This project description information is requested per Section 4-201(8). Noble Response: Any drilling will be permitted/approved according to COGCC via the submittal of a Form 2. All items not associated with a proposed drilling operation will be removed prior to establishment of drilling operations. Reclamation of the site will be according to the plan attached to this response. 5. The Reclamation Plan states that it is for a "compressor station". Please provide a reclamation plan which is site specific and demonstrates compliance with Section 7-208 of the LUDC. Noble Response: See revised Reclamation Plan included with this response. 6. That application represents that "all of Noble's surface disturbances are covered under a statewide bond" (Standards Analysis P. 7). Please include this information with the reclamation plan. If this bonding is associated with Noble's drilling operations and tied to this particular APD, please submit the necessary documentation to support this claim. Noble Response: See attached Surety Detail from the COGCC. This $25,000 rider is a blanket bond that covers Noble’s surface disturbances. Power of Attorney (POA) from Noble Energy, Inc. and Authorization 7. As with Savage-Noble LPAA 7824, Noble's Power of Attorney from 2010 to Robert Hoelsken has expired. Robert authorized Linda Pavelka and Jim Kirkpatrick to act on Noble's behalf. Since Mr. Hoelskin's authority expired, this authorization is invalid. The consent letter signed by the owners of the property is also signed by Jim Kirkpatrick who has no authority. Linda Pavelka signed as applicant and billing contact, but she has no authority and does not have the authority to designate Olsson as Noble's agent. As such, the authorization is not valid. A new POA from Noble and updated letters of authorization need to be provided. Noble Energy, Inc. Limited Impact Review Land Use Change Permit – Ramos Laydown Yard – Storage Garfield County File Number LIPA-7825 NTC Response Page 3 Noble Response: Please see Power of Attorney from Noble Energy, Inc. to Mari Gillman.

Noble Response: A phone conference was conducted between Noble and the Assistant County Attorney, Kelly Cave, on May 16, 2014, which clarified Noble’s position on the existence of permanent easements. Attorney Cave indicated the documentation provided by Noble is sufficient to demonstrate legal access to project sites. See Access Easement Agreement effective November 20, 2007, Rec. No. 747409, and Extension of Surface Lease, dated May 10, 2012, Rec. No. 818669. The easement is formally granted for the term of this agreement.
