As produced water is generated from existing wells, the water is collected / transported to one of the Centralized E&P waste management facilities for further treatment and potential re-use / recycling during hydraulic fracturing operations. The “finished” water from the treatment facility has been treated to remove any residual hydrocarbon content that was not separated at the well-head. After treatment, the treated water may then be “re-used / recycled” during hydraulic fracturing operations where the water is pumped from a Centralized E&P waste management facility to a series of remote storage ponds where the water is staged and ultimately re-used / recycled for hydraulic fracturing operations. Hydraulic fracturing operations is a highly water intensive activity and re-using / recycling produced water serves to protect and reserve freshwater resources. Third Party Disposal Facilities Third party disposal facilities are an option available to TEP for management and disposal of produced water. However, because this option requires trucking to a distant commercial disposal facility, this is typically considered to be a labor-intensive option, is not cost effective for TEP, and therefore, is not a preferred option. There are six Third-Party, commercial disposal facilities that are locally / regionally available to TEP operations (see Table 4). Typically, TEP would only use a third-party commercial disposal facility for produced water disposal if our existing water treatment facilities were full (at maximum capacity) and/or TEP’s permitted injection wells were incapacitated (not available) for some reason.

All spills are immediately investigated by TEP Environmental and Operations personnel. Contaminated soils are assessed to determine if they exceed regulatory cleanup standards and require removal, treatment, or disposal. Characterizing potentially contaminated soils is accomplished either by field-screening the impacted soils to determine relative hydrocarbon concentrations, and/or by collecting samples of the impacted soils and sending the samples to an approved commercial lab for analysis. All contaminated soils exceeding regulatory cleanup standards are excavated and managed / disposed of appropriately. If a spill incident is subject to agency reporting requirements, the appropriate agencies are notified within the regulatory timelines. Impacted soils that exceed applicable cleanup standards are typically excavated and taken to an off-site commercial disposal facility that is authorized to accept that type of waste. Sewage Chemical toilets (i.e., porta potties) will be provided on site for personnel use during construction, drilling, and completions operations. Porta potties will be emptied weekly by an approved sanitary waste contractor and hauled to an approved sanitary waste disposal facility. Please see the Waste Handling Table (Table 5) for additional details. Garbage All garbage and trash (i.e., solid, non-hazardous wastes) will be stored in enclosed bear-proof trash containers. Disposal of garbage and trash will occur approximately once per week during drilling and completions operations. All garbage and trash will be transported to a permitted solid waste landfill Page 11 of 12 within one (1) week following termination of drilling or completion operations. Garbage or trash will not be disposed of on-location. The well site and access road will be kept free of trash and debris during long-term production operations. No hazardous substances or hazardous wastes are anticipated to be generated during construction, drilling, and completions operations. Such materials are strictly prohibited for disposal at a solid waste landfill. Please see the Waste Handling Table (Table 5) for additional details. RECORD KEEPING TEP will comply with COGCC Rule 905.b.(3), Waste Generator Requirement, which states that operators that generates E&P Waste that is transported off-site will maintain records of invoices, bills, or tickets for a minimum of five (5) years including the following information: 1. The date of the transport; 2. The identity of the waste generator; 3. The identity of the waste transporter; 4. The location of the waste pickup site; 5. The type and volume of waste; and 6. The name and location of the treatment or disposal site. Records will be maintained in compliance with COGCC Rule 206, Recordkeeping and Access to Records. Records will be maintained at TEP’s main field office in Parachute, CO. TEP will maintain facility inspection forms, maintenance documentation, analytical sample data, storm water management and weed control documentation, operational data, and any other information relative to the operation of this facility. BEST MANAGEMENT PRACTICES 1) TEP will properly characterize and dispose of all waste streams at facilities approved for acceptance of each waste stream; 2) TEP will properly characterize and dispose of all waste at the appropriate specific landfill/waste disposal location that allows for acceptance of the particular waste stream. 3) No offsite disposal of cuttings to another oil and gas location shall occur without prior approval of an amended Waste Management Plan specifying disposal location and waste characterization method; commercial disposal of drill cuttings and drilling fluids will only require the operator to maintain documentation (manifests, bills of lading) of drill cuttings and drilling fluids disposal; the operator will implement measures (covers, misting) in trucks to reduce dust and PM emissions during transport of WBM solids and cuttings materials from the well pad location; SUMMARY As described above, development of the proposed wells on the South Leverich 13-09 pad will produce waste fluids and materials which will be managed in accordance with all Federal, State, and local guidelines.

INTRODUCTION TEP Rocky Mountain LLC (hereafter “TEP”) has developed the following topsoil protection plan to address compliance with Federal, State, and local requirements regarding topsoil management and preservation during construction of the South Leverich 13-09 well pad and pipeline. Proper management of topsoil from the Oil and Gas Location during initial site construction is necessary to ensure topsoil is preserved for site reclamation—following completion of development of the well pad and pipeline corridor—and to ensure adequate organic material for the re-establishment of desirable vegetation is available at reclamation (restoring the land as nearly as practicable to its condition at commencement of drilling and production operations). RULE 1002. SITE PREPARATION AND STABILIZATION There are two components of the South Leverich 13-09 Oil and Gas Location that require removal and temporary storage of topsoil: construction of the South Leverich 13-09 well pad (6.43 acres) and pipeline corridor (1.83 acres). Topsoil stripped during initial construction of these project components will be managed according to use and duration of development. Prior to separation and storage of the topsoil horizon, or top six (6) inches, from the well pad facility and pipeline corridor, woody vegetation will be mulched and stormwater control measures properly installed to control erosion and sedimentation during precipitation events. (Please refer to the Stormwater Management Plan attached to the Form 2A for details on planned stormwater control measures.) When separating soil horizons, TEP will segregate each horizon based upon noted changes in physical characteristics, such as organic content, color, texture, density, or consistency. To the extent feasible, stockpiled soils will be protected from degradation due to contamination, compaction, and from wind and water erosion during drilling and production operations. Surface roughening, temporary seeding and mulching, erosion control blankets, or soil binders will be used as needed, and best management practices implemented, to prevent weed establishment and to maintain soil microbial activity. South Leverich 13-09 Well Pad During construction of the well pad, TEP’s excavation contractor will strip the topsoil horizon between the top of cut and toe of fill slopes. Topsoil will be stripped to a depth no less than six inches (6”) and stockpiled south of the existing well pad. Topsoil will be segregated from other subsurface materials disturbed during well pad construction activities and no topsoil will be used for building the location or left in place and covered by subsoil in a cut and fill situation. To control sedimentation, wattles will be properly installed around the base of topsoil stockpiles and a metal sign (11” x 17”) with the wording “Topsoil Stockpile” will be placed on the north (pad) side of the stockpile area. Upon completion of well pad construction activities, hydro-seed/mulch will be applied to topsoil stockpiles to stabilize the soils and promote the growth of desirable plants until interim reclamation can be completed. • Quantity of topsoil that will be disturbed for the well pad: approximately 2,920 cubic yards (based on 6” depth, not including the working surface). • Location of topsoil that will be disturbed: Please see Requirement 8: Scaled Diagram Showing Topsoil Stockpile Locations below. When drilling and completion operations and recontouring of the site are complete (as described in the Interim Reclamation Plan), topsoil will be moved from the stockpile area and placed over the facility’s cut and fill slopes. Following the uniform placement of topsoil over cut and fill slopes, hydro-seed/mulch will be applied to stabilize soils to promote the growth of desirable vegetation. The facility’s Interim Reclamation Plan provides specific details about the materials and methods to be used for interim reclamation of the stockpile area. Proposed Pipeline Corridor During construction of the pipeline corridor, TEP’s pipeline installation contractor will strip the topsoil horizon within the 50’ wide corridor pipeline right-of-way (ROW) width and place the material along the downhill side. Topsoil will be segregated from subsurface materials excavated during pipeline installation and stockpiled upslope of the trench. When construction is complete and the pipeline ROW has been re- contoured to pre-construction slopes, stripped topsoil will be uniformly re-placed across the disturbance. • Quantity of pipeline corridor topsoil that will be disturbed: approximately 1,476 cubic yards (based on 6” average depth). • Location of topsoil that will be disturbed: topsoil will be stripped from the pipeline ROW and windrowed along the downhill side of the ROW. Following the uniform placement of topsoil, the pipeline ROW will be hydro-seeded/mulched to stabilize the soil and promote growth of desirable vegetation. The project’s Reclamation Plan, attached to the Form 2A, provides specific details about the reclamation materials and methods to be used for the pipeline corridor.

Leverich 13-09 Natural Resources Conservation Service September 6, 2021 USDA ~ NRCS 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 (https://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.

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. Custom Soil Resource Report 9 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. 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 Custom Soil Resource Report 10 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.

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 Erosion Factors Soil Erosion Factors are soil properties and interpretations used in evaluating the soil for potential erosion. Example soil erosion factors can include K factor for the whole soil or on a rock free basis, T factor, wind erodibility group and wind erodibility index. K Factor, Whole Soil Erosion factor K indicates the susceptibility of a soil to sheet and rill erosion by water. Factor K is one of six factors used in the Universal Soil Loss Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE) to predict the average annual rate of soil loss by sheet and rill erosion in tons per acre per year. The estimates are based primarily on percentage of silt, sand, and organic matter and on soil structure and saturated hydraulic conductivity (Ksat). Values of K range from 0.02 to 0.69. Other factors being equal, the higher the value, the more susceptible the soil is to sheet and rill erosion by water. "Erosion factor Kw (whole soil)" indicates the erodibility of the whole soil. The estimates are modified by the presence of rock fragments. Factor K does not apply to organic horizons and is not reported for those layers. 28 29 Custom Soil Resource Report Map—K Factor, Whole Soil 4368200436850043688004369100436940043697004370000437030043706004370900437120043682004368500436880043691004369400436970043700004370300437060043709004371200255800 256100 256400 256700 257000 257300 257600 257900 255800 256100 256400 256700 257000 257300 257600 257900 39° 27' 24'' N 107° 50' 21'' W39° 27' 24'' N107° 48' 42'' W39° 25' 42'' N 107° 50' 21'' W39° 25' 42'' N 107° 48' 42'' WN Map projection: Web Mercator Corner coordinates: WGS84 Edge tics: UTM Zone 13N WGS84 0 500 1000 2000 3000Feet 0 200 400 800 1200Meters Map Scale: 1:15,300 if printed on A portrait (8.5" x 11") sheet.

A map unit is typically composed of one or more "components". A component is either some type of soil or some nonsoil entity, e.g., rock outcrop. For the attribute being aggregated, the first step of the aggregation process is to derive one attribute value for each of a map unit's components. From this set of component attributes, Custom Soil Resource Report 32 the next step of the aggregation process derives a single value that represents the map unit as a whole. Once a single value for each map unit is derived, a thematic map for soil map units can be rendered. Aggregation must be done because, on any soil map, map units are delineated but components are not. For each of a map unit's components, a corresponding percent composition is recorded. A percent composition of 60 indicates that the corresponding component typically makes up approximately 60% of the map unit. Percent composition is a critical factor in some, but not all, aggregation methods. The aggregation method "Dominant Condition" first groups like attribute values for the components in a map unit. For each group, percent composition is set to the sum of the percent composition of all components participating in that group. These groups now represent "conditions" rather than components. The attribute value associated with the group with the highest cumulative percent composition is returned. If more than one group shares the highest cumulative percent composition, the corresponding "tie-break" rule determines which value should be returned. The "tie-break" rule indicates whether the lower or higher group value should be returned in the case of a percent composition tie. The result returned by this aggregation method represents the dominant condition throughout the map unit only when no tie has occurred. Component Percent Cutoff: None Specified Components whose percent composition is below the cutoff value will not be considered. If no cutoff value is specified, all components in the database will be considered. The data for some contrasting soils of minor extent may not be in the database, and therefore are not considered. Tie-break Rule: Higher The tie-break rule indicates which value should be selected from a set of multiple candidate values, or which value should be selected in the event of a percent composition tie. Layer Options (Horizon Aggregation Method): Surface Layer (Not applicable) For an attribute of a soil horizon, a depth qualification must be specified. In most cases it is probably most appropriate to specify a fixed depth range, either in centimeters or inches. The Bottom Depth must be greater than the Top Depth, and the Top Depth can be greater than zero. The choice of "inches" or "centimeters" only applies to the depth of soil to be evaluated. It has no influence on the units of measure the data are presented in. When "Surface Layer" is specified as the depth qualifier, only the surface layer or horizon is considered when deriving a value for a component, but keep in mind that the thickness of the surface layer varies from component to component. When "All Layers" is specified as the depth qualifier, all layers recorded for a component are considered when deriving the value for that component. Whenever more than one layer or horizon is considered when deriving a value for a component, and the attribute being aggregated is a numeric attribute, a weighted average value is returned, where the weighting factor is the layer or horizon thickness. Custom Soil Resource Report 33 Soil Qualities and Features Soil qualities are behavior and performance attributes that are not directly measured, but are inferred from observations of dynamic conditions and from soil properties. Example soil qualities include natural drainage, and frost action. Soil features are attributes that are not directly part of the soil. Example soil features include slope and depth to restrictive layer. These features can greatly impact the use and management of the soil. Hydrologic Soil Group Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

Topsoil will be stripped to a depth no less than six inches (6”) and stockpiled south of the existing pad location. Topsoil will be segregated from all subsurface materials disturbed during well pad construction and no topsoil will be used for building the location or will be left in place and covered by subsoil in a cut and fill situation. Proposed Pipeline Corridor During construction of the pipeline corridor, approximately 1,476 cubic yards of topsoil within the pipeline right-of-way (ROW) will be salvaged. Topsoil will be stripped to a depth no less than six -inches (6”) and windrowed along the downhill side of the ROW. Topsoil will be segregated from all other subsurface materials disturbed during pipeline construction and no topsoil will be used for construction of the corridor or will be left in place and covered by subsoil in a cut and fill situation. REQUIREMENT 10: DESCRIPTION OF MEASURED TOPSOIL DEPTHS South Leverich 13-09 Oil and Gas Location Soil Pit Profile Description The South Leverich 13-09 facility is primarily located in mixed mountain shrubland; dominant plant types include brush and mountain sagebrush, and lesser types include Aspen trees and perennial and annual grasses. Six (6) samples were collected from two NRCS-defined soil type areas: • One (1) for the pipeline corridor soil type 45 • One (1) for the pipeline corridor soil type 16 • One (1) for the well pad soil type 16 • Three (3) for the well pad soil type 45 Soil profiles did not include Horizon O and the topsoil Horizon A was moderately developed and appeared to have a high mineral to organic matter ratio and moderate to poor plant rooting. Soil samples were collected by hand from the surface to depths of 6” to meet the minimum depth requirement for topsoil sample collections (COGCC reclamation rule 1002.B). From the sample locations, no topsoil horizons extended more than 12” below the surface elevation and measured topsoil depths among soil pit and sample locations varied. Horizon A, or topsoil horizon, averaged: • Approximately 8.5” thickness for NRCS soil type 16 • Approximately 10.3” thickness for NRCS soil type 45 The topsoil horizon was defined as an A horizon containing mixed organic material and mineral content, with minerals and some organics identified in shallow, root-dense layers of the soil profile. REQUIREMENT 11: DESCRIPTION OF BMPs FOR SHORT- AND LONG- TERM STABILIZATION OF TOPSOIL STOCKPILES RULE 1002. INTRODUCTION During construction activities, topsoil stockpiles may be formed with soils removed from and segregated for roads, pipelines, well pads, and other TEP facilities. The preserved soils will be used to re-contour disturbed surfaces or for reclamation/restoration of disturbed areas that will utilize vegetative final stabilization. Stockpiles will be protected from degradation due to contamination, compaction, and, to t he extent practicable, from wind and water erosion during drilling and production operations. Best management practices (BMPs) to prevent weed establishment and to maintain soil microbial activity will be implemented. BMPs for Short-Term Stabilization Proper stockpile construction (e.g., away from drainages, with 2:1 slopes, proper heights, and control measures downgradient) and management should help to preserve the chemical and biological integrity of topsoil. According to site conditions, the following BMPs may be used to stabilize topsoil stockpiles in the initial phase of construction. • Protection from Contamination: based on changes in physical characteristics (e.g., organic content, color, texture, density, or consistency), soil horizons will be segregated and stockpiled separately; stockpiles of different soil types will be separated by compacted earthen berms, sediment control logs, straw bale barriers, etc.; and stockpile surfaces will be stabilized to control for erosion and sedimentation. • Protection from Compaction: topsoil stockpiles will be indicated on site with signage; stockpiles will be placed in areas away from vehicle and equipment traffic; and when stockpiling, compaction will be minimized by limiting the number of equipment passes, limiting stockpile height, and using vegetation. • Protection from Wind Erosion: surface roughening, applying hydro-seed/mulch, using soil tackifier, covering stockpiles with rolled erosion control products, etc. • Protection from Water Erosion: surface roughening, applying hydro-seed/mulch, using soil tackifier, covering stockpiles with rolled erosion control products, etc. • Weed Establishment Prevention: TEP uses cultural, mechanical, biological, and chemical controls to prevent the establishment of weeds. TEP’s complete Weed Control plan is included in Requirement 12 below. BMPs for Long-Term Stabilization Interim reclamation: When drilling and completion operations and recontouring of the site are complete (as described in the Interim Reclamation Plan), all topsoil will be moved from the stockpile area and placed over the facility’s cut and fill slopes to ensure long term topsoil health including protection from erosion, prevention of weed establishment, and maintenance of soil microbial activity until final reclamation. The following BMPs will be used after topsoil placement is complete on cut and fill slopes. • The seed bed will be prepared on all topsoiled areas to alleviate compaction and minimize the potential for erosion. • Topsoiled areas will be planted with desirable species or a seed mixture provided by the Surface Owner for this particular location. • Protection from Wind and Water Erosion: topsoiled areas will be covered with certified weed free mulch at an application rate specified by the product’s manufacturer, or a specification sheet that follows good engineering practices. • Weed Establishment Prevention: TEP uses cultural, mechanical, biological, and chemical controls to prevent the establishment of weeds. TEP’s complete Weed Control plan is included below in Requirement 12. Final reclamation: During final reclamation, topsoil will be stripped from cut and fill slopes and stockpiled during the final recontouring of the facility. BMP practices listed in the short-term stabilization will be used. Once recontouring is complete, topsoil will be moved from the stockpile area and placed over surfaces recontoured for final reclamation. The following BMPs will be used after topsoil placement is complete on finally reclaimed surfaces. • The seed bed will be prepared on all topsoiled areas to alleviate compaction and minimize the potential for erosion. • Topsoiled areas will be planted with desirable species or a seed mixture provided by the surface owner for this particular location. • Protection from Wind and Water Erosion: topsoiled areas will be covered with certified weed free mulches at an application rate specified by the product’s manufacturer, or a specification sheet that follows good engineering practices. • Weed Establishment Prevention: TEP uses cultural, mechanical, biological, and chemical controls to prevent the establishment of weeds.

These areas include well pads, lease roads, disturbed sites, reclaimed sites, as well as some undisturbed areas. In order to minimize impacts that may result from the presence of noxious weeds, improve reclamation success, and ensure good land stewardship, TEP has adopted the following Integrated Noxious Weed Management Plan. The Weed management plan is designed to bring TEP into compliance with the Colorado Noxious Weed Act (C.R.S. Title 35, Article 5.5), Colorado Oil & Gas Conservation Act, the Rio Blanco County Noxious Weed Management Plan, and the BLM Gold Book. Weed Management activities will primarily focus on the Colorado Noxious Weed List and the Rio Blanco County Noxious Weed List (see list below). TEP’s Integrated Weed Management plan will focus four key components of weed management.  Prevention  Inventory and Mapping  Weed Control  Monitoring Prevention - Prevention is a key component of the TEP weed management program. TEP addresses prevention in the planning, development, and operations phases of field development. TEP tries to avoid or limit ground disturbance activities when practical. If ground disturbing activities cannot be avoided, TEP tries to plan development that will avoid identified weed infestation or areas where weed establishment may be more optimal if this is practical to operations. If ground disturbing activities do occur, TEP uses temporary or permanent seed mixes that help to develop healthy stands of vegetation that can be self sustaining and deter the establishment of invasive species. Inventory and Mapping – TEP uses various means to inventory noxious weeds that fall within its lease boundaries. First, members of TEP Environmental staff are trained in weed identification and note noxious weed occurrences when they are completing field work. Second, the environmental staff works to educate field operations staff to identify weed infestations so that they can also document infestations and inform environmental staff where those infestations occur. If operations personnel are unsure of a suspected infestation, they contact the Environmental staff, and the suspected infestation is then investigated before it is documented. Third, TEP hires a Certified Weed Applicator to do its bare ground and noxious weed spraying. While the Applicator is conducting their annual spraying activities they are required to GPS infestations they find and treat for a company inventory and also for annual reporting. Lastly, many of the lands that TEP operates on are also used for livestock grazing or agricultural purposes and TEP works with the lessees to document weed infestations that the lessees may identify. Weed Control – TEP uses an Integrated Weed Management Approach for the control of identified noxious weed infestations. This is made up of four control methods. These include Cultural, Mechanical, Biological, and Chemical.  Cultural – Cultural control is the use of management practices that will help to favor the growth of desirable species over undesirable species. This establishment is accomplished by using appropriate seed mixes that reflect the surrounding area or species that have been developed and are approved for rapid stabilization of a site. Purchased seed and mulch is certified weed free to decrease the opportunity for noxious weed species to be introduced into disturbed sites.  Mechanical – Mechanical controls methods most often used by TEP include the following. Mowing, tillage, and hand pulling. However, because mechanical methods tend to be fairly labor intensive and cost prohibitive, it is not typically a preferred method but can be used in sensitive areas or areas where topography or other environmental factors may be considered prohibitive.  Biological - Biological Control Methods are the release of organisms that are known to be effective in controlling specific weed species. This method may be chosen if there is a heavy infestation of a specific species on a site. TEP will consult with the Colorado Department of Agriculture Insectary located in Palisade, Colorado when exploring control options. The BLM will also be consulted if this method is being considered on federally controlled lands.  Chemical – Chemical control is the use of herbicides to control weed populations. This is the primary weed control method used by TEP. TEP annually contracts a Certified Commercial applicator to apply herbicides on lease acreage. Both bare ground and noxious weed applications occur throughout spring, summer, and fall. TEP encourages the use of spot spray application on lease land to ensure vegetation diversity components are maintained. Broadcast applications are only used if a weed infestation is extremely heavy and has created a monoculture in the infested area. The use of appropriate PPE, pesticide storage, pesticide handling, spray mixtures and application rates will occur on TEP lease acreage. Monitoring – Areas where noxious weed infestations are identified and treated will be inspected over time to ensure that control methods are working to reduce and suppress the identified infestation. The sites will be monitored until the infestations are eliminated or reduced to acceptable levels. These inspections will be used to prioritize future weed control efforts.

Additionally, this plan provides site specific stormwater management control measures that will be employed during development of the South Leverich 13-09 pad to ensure compliance with COGCC, Colorado Department of Public Health and Environment, and Federal regulations. TEP has developed a Field Wide Storm Water Management Plan (SWMP) in compliance with the CDPHE’s Colorado Discharge Permit System (CDPS) and to ensure conformance to the stormwater management standards under COGCC Rule 1002.f. The SWMP will identify possible pollutant sources that may contribute pollutants to stormwater, and identify Best Management Practices (BMPs) that, when implemented, will reduce, or eliminate any possible water quality impacts. TEP has also developed a field wide Post-Construction Stormwater Management Plan (PC-SWMP) as required by COGCC Rule 1002.f.(3) to ensure that Best Management Practices (BMPs) are implemented on all subject oil and gas locations under its management where the Construction Storm Water permit issued by CDPHE has been terminated. The PC-SWMP identifies possible pollutant sources that may contribute pollutants to stormwater during the post-construction and reclamation phase of operations and describes BMPs to control stormwater runoff in a manner that minimizes erosion, transport of sediment offsite, transport of pollutants offsite, or degradation of site conditions. Upon request by the COGCC or the director, TEP will provide the SWMP and / or PC-SWMP for review. TEP is proposing to drill, complete, and operate twenty-one (21) directional natural gas wells from the existing South Leverich 13-09 pad located on private surface owned by TEP overlying Fee minerals. The South Leverich 13-09 pad is an existing oil and gas location (COGCC Loc ID: 335045) with four (4) natural gas wells producing from the underlying Fee lease. The existing oil and gas location is located on resource / rangeland within Lot 3 and Lot 4 of Section 13, Township 7 South, Range 94 West, 6th P.M., within Garfield County, Colorado. The South Leverich 13-09 pad would be reconstructed and slightly expanded to accommodate the development of the twenty-one (21) new proposed directional wells. The existing access road from Garfield County Road 317/317A will be used to access the existing oil and gas location. Development of the twenty-one (21) proposed wells on the South Leverich 13-09 pad would also require the construction of two (2) new pipelines, one to support gas gathering operations and the other to support transport of produced water. Other existing facilities including the Youberg SR 43-12 pad (COGCC Loc ID: 413683), Youberg RU 44-7 pad (COGCC Loc ID: 439173), and the Beaver Creek Pit (Pit 11-7-793; COGCC Loc ID: 432702), would be utilized as support facilities for development of the proposed wells on the South Leverich 13-09 pad. Development Phases: Each phase of development requires the implementation and maintenance of both structural and non-structural stormwater management control measures used by TEP to effectively minimize site erosion and sediment transport. The following outlines the typical development phase which is described in greater detail below. 1) Pre-Construction Phase 2) Construction Phase (pad, road, and pipeline) 3) Interim Reclamation Phase 4) Final Reclamation Phase Page 3 of 14 Please see Appendix A, Construction Layout, and Appendix B, Interim Reclamation Layout, which depict preliminary site-specific stormwater control measures planned for installation at the South Leverich 13-09 pad during both initial construction and interim reclamation of the oil and gas location. SUPPLEMENTAL SITE INFORMATION The South Leverich 13-09 pad is an existing 5.44-acre oil and gas location that would be reconstructed and expanded to a 6.43-acre footprint to support drilling and completion operations of twenty-one (21) proposed natural gas wells. The long-term disturbance of the South Leverich 13-09 pad would be approximately 1.74-acres. Approximately 4.69-acres of the oil and gas location would be reclaimed following completion of well construction. Soils: The National Resource Conservation Service (“NRCS”) identifies the dominate soil types within the boundary of the South Leverich 13-09 pad as the Morval-Tridell complex and the Cimarron loam. The Morval-Tridel complex soil type is associated with alluvial fans and was derived from sandstone and/or basalt. The typical profile to a depth of 5 inches is defined as loam, 5-17 inches defined as clay loam, 17- 27 inches defined as stony clay loam, and 27-60 inches defined as stony loam. The Cimarron loam soil type is associated with valleys or drainageways and was derived from basalt. The typical profile to a depth of 4 inches is defined as loam, 4-16 inches is defined as silty clay loam, and 16-60 inches is defined as silty clay. The NRCS reports that these soils are classified, under the Uniform Soils Classification System, as inorganic clays (CL). These soils have a reported hydrologic group rating of C, having a slow infiltration rate when thoroughly wet. The infiltration rate is listed as moderately low to moderately high ranging from 0.06 to 0.60 inches per hour. The NRCS lists the Flood Frequency Class for the facility location as “None”. “None” means that flooding is not probable, and the chance of flooding is nearly zero percent in any year. NRCS reports that the Erosion factor K (whole soil) of 0.28 for the site, or moderately susceptible to erosion by water. Erosion factor K indicates the susceptibility of a soil to sheet and rill erosion by water. Factor K is one of six factors used in the Universal Soil Loss Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE) to predict the average annual rate of soil loss by sheet and rill erosion in tons per acre per year. The estimates are based primarily on percentage of silt, sand, and organic matter and on soil structure and saturated hydraulic conductivity (Ksat). Values of K range from 0.02 to 0.69. Other factors being equal, the higher the value, the more susceptible the soil is to sheet and rill erosion by water. Stormwater BMPs will be implemented to control soil erosion. Vegetation Description: The primary vegetation communities within the project area include Wyoming big sagebrush, Gambel’s oak, serviceberry, Rocky Mountain maple, and quaking aspen. A comprehensive list of common plant species within the project area can be found in the Biological Survey Report attached to the Form 2A. Since the South Leverich 13-09 pad is an existing oil and gas location, a pre-disturbance vegetation cover evaluation would not provide an accurate assessment of vegetation cover at the site. However, a vegetation assessment was completed for the reference area, which determined that precent cover for pre-disturbance conditions are approximately 98%. Please see the vegetation assessment included in the Biological Survey for additional details. Weed Infestations: WestWater Engineering (“WestWater”) conducted a biological survey which included a survey for weeds within the project area. WestWater identified several noxious weed infestations within the project area including State Listed B and C noxious weeds. Please see the Biological Survey Report attached to the Form 2A for additional detail on noxious weeds, including a list of the noxious weed observed within the project area. Non-Stormwater Discharges: Non-stormwater discharges are limited to application of fresh water along the existing access road and well pad. Excavation activities associated with the proposed activities are not Page 4 of 14 expected to impact groundwater. However, ground water encountered during excavation will be addressed in accordance with Federal and State regulations. Receiving Water: Beaver Creek, a perennial stream which is located west of the Oil and Gas Location approximately 640 feet, is the nearest surface water feature downgradient of the South Leverich 13-09 pad. Two (2) other unnamed intermittent drainages are located northeast of the Oil and Gas Location but are topographically isolated. Stormwater control measure described below will minimize the potential for impacts to surface water features. STORMWATER MANAGEMENT CONTROL MEASURES Potential Pollution Sources and Locations: Stormwater management control measures will be implemented to minimize the potential for pollution. The following potential pollution source have been identified as part of planned activities on the South Leverich 13-09 pad: 1) Transport of chemicals and materials, including loading and unloading operations Spill prevention during loading and unloading is outlined in TEP’s Piceance Basin Spill Prevention and Response Plan (“SPRP”) and Integrated Spill Prevention, Control, and Countermeasures (“SPCC”) Plan. TEP complies with applicable DOT requirements when transporting chemicals and materials to oil and gas locations. 2) Vehicle/equipment fueling Equipment is only fueled in designated fueling areas. Proper storage and transport of fuels is described below. 3) Outdoor storage activities, including those for chemicals and additives Material or chemicals brought to or produced on the oil and gas location will be handled properly using good housekeeping practices. TEP’s SPCC and SPRP plans address storage and handling procedures including guidelines for materials handling, storage container labeling, elevation, sealing, covering, securing, and secondary containment, as described below. 4) Produced water and drilling fluids storage Guidelines for storing produced water, drilling fluids, fuels, and chemicals include the following.  All containers will be clearly labeled.  Dry materials will be stored on pallets and covered when not in use to avoid contact with precipitation, stormwater, and wind.  Potentially hazardous liquid materials in buckets, drums or tanks will be stored within secondary containment, such as soil berms, steel containers or bermed visqueen, to capture accidental spills or leaks. Drums will be kept off the ground within secondary containment and stored under cover, if needed. The berms shall be constructed such that they are sufficiently impervious to prevent the material from being released beyond the confines of the containment system.  Fuel tanks will be stored within secondary containment.  Container lids will be securely fastened.  In the event of a spill, procedures outlined in TEP’s SPRP will be followed. Persons trained in handling spills will be available.
