Responses to USR Questionnaire Planning Questions: 1. Explain, in detail the proposed use of the property. This USR application is being submitted by Enerplus Resources (USA) Corporation (Enerplus) for the Orca Centralized Gathering Facility. Enerplus proposes to build a centralized gathering facility with gas compression and gas processing capabilities. This facility will also act as centralized gathering facility for produced water and oil for Enerplus wells in this area. This site will also house an Enerplus field office, storage yard, produced water recycling, and SWD well. The proposed use is consistent with the comprehensive county plan to foster development of the natural resources of Weld County. Given the size of the property, only a small amount of agricultural land would be affected. The facility will service low pressure gas (10"), oil (6-8"1, and produced water (4-6") pipelines entering from the east and west directions with a high-pressure gas discharge pipeline exiting the facility to the east. . Consistency with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. The Weld County Comprehensive Plan addresses goals and policies for agriculturally zoned properties, oil and gas deposits, as well as environmental pollutants that gathering facilities may emit. A goal of the Comprehensive Plan encourages the division of land in agricultural areas to support the continuation of agricultural production. The site is currently owned and used by Enerplus for agricultural purposes. Finally, the Comprehensive Plan addresses the presence of oil and gas deposits in the County and encourages the extraction of oil and gas resources by methods that conserve and minimize the impact on surrounding lands and land uses. The centralized gathering facility will allow for tankless well production sites which will in turn reduce the amount of land required at production sites on agricultural lands in the surrounding area. The proposed use is consistent with Chapter 22 and any other applicable code provisions or ordinance in effect. Section 22-5-100.A. (OG.Goal 1.) states, "Promote the reasonable and orderly exploration and development of oil and gas mineral resources," while Section 22-5-100.B. (OG..Goai 2.) strives to, "Ensure that the extraction of oil and gas resources conserves the land and minimizes the impact on surrounding land and the existing surrounding land uses." Section 22-5-100.B., (O .Policy 2.9.) outlines the objective to, "Impose protective measures through available state, County and federal regulations to ensure that the mineral operator conducts operations in a manner that will minimize current and future environmental impacts!' This Use by Special Review application for a centralized gathering facility, due to increases in drilling activity and anticipated production increases by producers in the Weld County area, remains consistent with the goals of Chapter 22. 3. Consistency with the intent of the Yield County Code, Chapter 23 (Zoning) and the zone district in which it is located. Oil and gas facilities are allowed as a use by right in the A (Agricultural) Zone District. However, oil and gas support and service operations such as a gathering and compression require the approval of a Use by Special Review Permit. The proposed facility use is consistent with the intent of the A (Agricultural) Zone District. Section 23-3-40.A.2 of the Weld County Code provides for oil and gas production support and service. Enerplus Resources (USA) Corporation Page 3 Weld County Use by Special Review Application 4. Surrounding Uses and Compatibility with surrounding uses. There are currently no USR permits on the site. The facility does not interfere with the existing use of the area, and remains compatible with the current zoning. 5. Hours and days of Operation. This facility is designed to operate twenty-four (24) hours a day, seven (7) days a week, 365 days a year. 6. List the number of full time and/or part time employees proposed to work at this site. Five full time employees, and three-part time employees. 7. If shift work is proposed include the number of employees per shift. Shift work is not proposed. 8. List the number of people who will use this site. Include contractors, truck drivers, customers, volunteers, etc. This site will have truck traffic that will be determined by production rates throughout the field and pipeline capacity. The site will not be continuously manned, but will be visited several times per day by Enerplus operations employees. 9. If this is a dairy, livestock confinement operation, kennel, etc., list the number and type of animals. N/A 10. Describe the type of lot surface and the square footage of each type.

A parking lot size 50' x 300' is additionally planned. 11. How many parking spaces are proposed? How many handicapped (ADA)parking spaces are proposed? There will be 12 parking spaces with 2 additional parking space reserved for ADA compliant handicapped parking. 12. Explain existing and proposed landscaping. No current landscaping exists. Formal landscaping is not planned. 13. Describe the type of fence proposed for the site (e.g., Moot chain link with earth tone slats). 6 -foot chain link around the site perimeter with gated entry. 14. Describe the proposed screening for all parking and outdoor storage areas. Due to the isolated nature of this facility, no screening is proposed. 15. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. Planned reclamation procedures will follow the guidelines set forth in COGCC 1000 series rules "Reclamation Regulations" to establish proper reclamation of the land and soil affected by oil and gas operations and ensure the protection of the topsoil of said land during such operations. The surface of the land shall be restored as nearly as practicable to its condition at the commencement of construction and operations. Enerplus Resources (USA) Corporation Page 4 Weld County Use by Special Review Application 16. Who will provide fire protection to the site?

The proposed site development is located within a parcel with a total area of 161.88 acres. The site is predominantly irrigated field. A relatively small portion, approximately 50 acres, is being converted to an oil and gas gathering facility. Because of this proposed development, the overall parcel imperviousness would increase just 8.57% (2% to 10.57%) and the overall drainage pattern would not be changed. In the absence of any attenuation efforts, stormwater runoff from the developed areas would flow back to the irrigated field at points more than 170 feet upgradient of from neighboring properties. Full stormwater flood attenuation is required for this project and the attached report outlines measures intended to address water quality. This report is prepared in accordance with the Weld County Storm Drainage Criteria (WCSDC). and the Weld County Engineering and Construction Criteria (WCECC). Additionally, Urban Drainage and Flood Control District's Urban Storm Drainage Criteria Manual (USDCM). The proposed site would collect and detain the stormwater quality control volume (WQCV) for the developed areas and release as prescribed within the WCSDC by methods outlined in the USDCM. Therefore, the construction of the proposed ORCA Pad Centralized Gathering Facility complies with both the Weld county and UDFCD stormwater criteria. We look forward to your consideration and feedback of this Final Drainage Report.

General Location and Description 1.1. Location The ORCA Pad Centralized Gathering Facility is located in the Southwest quarter of Section 26, Township 8 North, Range 67 West of the 6th Principal Meridian, Weld County, Colorado. It is physically located of County Road 90 southeast of its' intersection with County Road 19. The proposed site is bounded by agricultural land to the north, west, south, and east. (Please see the Vicinity Map in the Appendix A). 1.2. Description of the Property The proposed site is located within a parcel with combined total area of approximately 161.88 acres. The site is predominantly irrigated field. A small portion, approximately 50 acres, is being converted to an oil and gas production facility. The site is located approximately 0.7 mile northeast of Black Hollow Reservoir. There are no major drainage or irrigation facilities across the site or within 200 feet of the site. The proposed site is within FEMA Panel ID 08123C0925E which is provided in Appendix A. Busch Entertainment Corporation owns the proposed site. When development is complete, the proposed gathering facility will consist of a single facility pad. The gathering facility pad will consist of 10 oil tanks, 10 water tanks, water pumps, oil pumps, ECD'sfflares, vapor recovery towers, vapor -recover units, pigging/metering/slug catchers, 2 separators, MCC, compressors, NGL storage and loadout, NGL skids, NGL electrical generators, NGL tanks, NGL valve trailers, SWD well, and disposal injection pumps. During the Drilling Phase of the project, temporary stormwater BMPs will be implemented to provide sediment and erosion control. Refer to the Construction Drawings and Stormwater Management Plan for the types, locations, and descriptions of implemented BMPs. During the Production Phase of the project, a majority of the disturbed area will be reclaimed and returned to agricultural land. Stormwater from the facility and well pads will be routed to permanent WO drainage facilities, including WQCV ponds/swales, emergency spillways, and outlet features. Swabs and diversion channels are also proposed to direct onsite and offsite stormwater appropriately. As determined by USDA Web Soil survey, the soils for the proposed site have been identified as Olney fine sandy loam (Hydrologic Type B). The existing site generally slopes from the north northeast to south southwest at a range of -1 % to 5% grades (Please see the Soil Properties Map in the Appendix A). Upon completion of development, the proposed site will be a combination of compacted gravel and concrete piers/pads. The existing ground was assumed to have a percent imperviousness of 2%. When developed, the well pad is assumed to be compacted gravel with a percent imperviousness of 40%. The Final Drainage Report for ORCA Gathering Facility Pad Page 1 enerPLus ASCENT GEOMATICS SOLUTIONS facility pad is assumed to be compacted gravel and concrete with a percent imperviousness of 40% and 100% respectively. To account for sedimentation, an imperviousness value of 90% was use for the WQCV ponds. The composite percent imperviousness will be 48.9% for the Basin I. The overall post -development imperviousness for the entire 161.88 acre parcel is 10.57% (Please see calculation in Appendix B and Proposed Drainage Plan for details). 2. Drainage Basins and Sub -Basins 2.1. Major Basin Description The site is located within the Black Hollow Creek Basin. The proposed site is associated with the Town of Windsor Master Drainage Plan: 2017 Update Volume I: Law Basin and Windsor Basin. As indicated in the FIRM map in Appendix A, the proposed site is not within the 100 -year floodplain. No irrigation facilities are located within 200 feet of the proposed site. 2.2. Sub -Basin Description Historical stormwater flows from the northeast to southwest at 1 to 5% grades. Currently, stormwater follows along a similar drainage pattern and flows to the southwest and eventually reaches the Black Hollow Reservoir. The property is bound on the south and east by dirt farm roads, and on the north and west by other parcels of irrigated farmland. For discussion in this report, 7 drainage basins have been identified within the 161.88 -acre parcel. See Drainage Plan drawings (Appendix D) for basin boundaries and contributing areas. • Basin (Onsite flows) is the 30.79 -acre area of the permanent gathering facility pad. Basin 1 includes the facility pad perimeter diversion swale and the water quality pond. The pad surface is not sloped. • Basin 2 — (offsite flows) is a 8.45 -acre offsite area that abuts the northwestern portion of Basin 1 and includes a diversion ditch along its southern border with Basin I. Basin 2 is farmland, and is surrounded by farmland to the north, west, and east. • Basin 3 — (Offsite flows) is a 5.40 -acre offsite area that lies to the northeast of Basin 1 and to the north of Basin 4. Basin 3 is farmland and is bounded by farmland to the north, west, and east. • Basin 4 - (Offsite flows) is a 1.05 -acre offsite area situated east of the permanent gathering facility pad. Basin 4 is is comprised of farmland and abuts farmland to the east, north, and south. • Basin — (Offsite flows) is a 0.99 -acre offsite area east of the gathering facility pad and south of Basin 4. Additionally, this basin is bounded to the east and south by Basin 6 which is comprised of farmland. Final Drainage Report for ORCA Gathering Facility Pad Page 2 enermaus ASCENT GEOMATICS SOLUTIONS • Basin 6 — (Offsite flows) is a 2.81 -acre offsite area southeast of the proposed gathering facility pad. This basin is bound by the proposed access road to the north, by the proposed gathering facility pad to the northwest, and by farmland to the south and east. • Basin 7 — (Offsite flows) is a 52.18 -acre offsite area north of the proposed gathering facility pad. Basin 7 is bound by farmland to the north and west, by an existing dirt road to the east, and by the proposed facility pad to the south. The basin is unaffected by the proposed development. • Basin 8 — (Offsite flows) is a 60.22 -acre area west of the proposed gathering facility pad. This basin is bounded by farmland to the north, west, and south, and by the proposed gathering facility pad to the east. Basin 8 is unaffected by the proposed development. 3. Drainage Design Criteria 3.1. Jevelopment Criteria Reference and Constraints The proposed site is associated with the Town of Windsor Master Drainage Plan: 2017 Update Volume I: Law Basin and Windsor Basin. Access to the proposed development is to be constructed east of an existing dirt road that extends south from County Road 90, past the eastern side of the site. Runoff from this project is to be routed to conform with the WCSDC and to mitigate potential negative impacts to adjacent properties. 3.2. Hydrological Criteria This proposed drainage plan follows Weld County's Storm Drainage Design Criteria (WCSDC) and the Weld County Engineering and Construction Criteria (WCECC). As per WCECC, the minor and major design storm frequency for water quality and detention pond designs is 10 years and 100 years. As per Section 5.4.1 Table 5-1, the associated one -hour point rainfalls for minor and major design storm frequencies are 1.76 inches and 2.78 inches respectively. As the on -site basin is less than 160 acres, the rational method was employed to compute runoff via the UD-Rational 2.00 workbook. The gathering facility pad drains into a WQCV Pond with an outlet structure orifice plate designed for a 40 -hour drain time. The WQCV pond emergency spillway has been designed to release at a rate equal to the 100 -year developed flow rate. The emergency spillway has been sized using UDFCD v3 ediment Basin SC -7, with Table SB-1 used to size the respective crest lengths. The composite percent imperviousness was calculated for each basin referencing Urban Storm Drainage Criteria Manual (USDCM) Table 6-3 Recommended percentage imperviousness values. Final Drainage Report for ORCA Gathering Facility Pad Page 3 enerts ASCENT GEOMATICS SOLUTIONS Please see Hydrological Calculation in Appendix B for details. 3.3. Hydraulic Criteria The hydraulic structure proposed on -site includes one detention pond with outlet structure and emergency spillway. The outlet structures of the detention pond were computed using the UDFCD UD- Detention._v2.34 spreadsheet. These hydraulic calculations include state storage sizing for Detention Basins, stage -Discharge sizing of the Water Quality Capture Volume (WV) Outlet, Restrictor Plate Sizing for Circular Vertical Orifices, Stage -Discharge Sizing of the Weirs and Orifices, stage -Discharge sizing of the outlet culvert, and Stage -Discharge Sizing of the Spillway. Water quality capture volume was determined with a 40 -hour time. The Water Quality trash screen size and trash rack over the outlet were calculated per USDCM V3 Chapter 4 Outlet Structure. The UD- Channels V1.05 spreadsheets were utilized to determine channel geometry and capacity. The UD- Culvert V3.05 spreadsheets were utilized to determine culvert geometry and capacity. Please see Hydraulic Computations in Appendix C for details. 4. Drainage Facility Design 4.1. General Concept To address water quality concerns, due to surface imperviousness changes, the proposed topography and features have been designed to control and detain flow from the developed areas and release that flow at a regulated rate. offsite flows will be diverted utilizing a series of channels away from the developed areas and released where they may resume historical flow patterns. The WOCV pond was sized based on proposed development. Any contributing offsite flows, from the undeveloped areas, were not accounted in sizing the WQCV ponds. However, these flows were accounted when sizing the emergency spillway. 4.2. Specific Details Basin I Stormwater from the gathering facility pad is collected in Diversion Channels 1 and 2 around the edge of the pad, and is conveyed west to Design Points 1 & 2 where the stormwater enters the 'QV pond at the southwest corner of the pad. Final Drainage Report for ORCA Gathering Facility Pad Page 4 enermaus ASCENT OEot,lafiiCS 'SOLUTIONS The catchment area of 15.18 acres with an imperviousness of 49.78%, a channel capable of conveying a 100 -year peak flow of 26.54 cfs is required. A channel (Diversion Channel 1 l Design Point 1) capable of conveying 31.8 cfs has been designed, with a 3:1 side slope and a total depth of 2.7 feet. The catchment area of 14.66 acres with an imperviousness of 45.22%, a channel capable of conveying a 100 -year peak flow of 25.95 cfs is required. A channel (Diversion Channel 2 / Design Point 2) capable of conveying 27.88 cfs has been designed, with a 3:1 side slope and a total depth of 2.55 feet. The UD-Detention v2.34 WQCV spreadsheet was used to size the stormwater detention pond. A 40 -hour drain time with a catchment imperviousness of 48.86% requires 2.618 ac -ft (114,656 cubic -feet) of stormwater detention volume. The proposed pond provides the calculated volume at elevation 5165.00' with a berm providing a minimum 1.0 foot of freeboard. Orifices in the outlet box (6 at 1.46 inches in diameter) were sized to facilitate drainage of the design volume within 40 hours. Using the USDCM Manual, V3, Construction BMP Fact Sheets, SC -7, Table B-1, an emergency spillway was designed to provide failure protection for the embankment in the event the outlet is clogged, or form storm volumes greater than the WQCV. The spillway is designed with 3:1 side slopes and a crest length of 12 feet. Basin 2 Stormwater from this area flows to the south, entering Diversion Channel 3 around the northern and northwestern edge of the gathering facility pad. The diversion ditch conveys the stormwater to the west away from the gathering facility pad and releases it into Basin 7 at Design Point 5 where it follows historic drainage patterns. For the catchment area of 8.45 acres with an imperviousness of 2.00%, a channel capable of conveying a 100 -year peak flow of 10.90 cfs is required. A channel (Diversion Channel 3 / Design Point 5) capable of conveying 11.45 cfs has been designed, with a 3:1 side slope and a total depth of 2.7 feet. Basin 3 Stormwater from this area flows to the south and is collected in Diversion Channel 4 at Design Point 6. Once in the diversion channel the stormwater is conveyed to the east and south through a culvert under the access road into Basin 6 at Design Point 10. The catchment area of 5.40 acres with an imperviousness of 2.41%, a channel capable of conveying a 100 -year peak flow of 10.49 cfs is required. A channel (Diversion Channel 3 / Design Point 6) capable of conveying 14.92 cfs has been designed, with a 3:1 side slope and a total depth of 2.3 feet. Final Drainage Report for ORCA Gathering Facility Pad Page 5 enermaus ASCENT GEOMATICS SOLUTIONS A 12" culvert, culvert 1, conveys the stormwater under the access road to Design Point 10, and is capable of conveying the 10-yr peak flow. The culvert is to be placed at the location indicated on the drainage plan and is set with a minimum slope of 2.4%. Basin 4 Stormwater from this offsite area sheet flows to the south Design Point 7 where it enters a culvert that conveys the stormwater under the access road into Basin 5. The catchment area of 1.05 acres with an imperviousness of 7.74%, a channel capable of conveying a 100 -year peak flow of 2.94 cfs is required. A channel (Diversion Channel 4 / Design Point 7) capable of conveying 2.98 cfs has been designed, with a 3:1 side slope and a total depth of 1.8 feet. To convey this stormwater under the proposed access road, culvert 2, a 12" culvert capable of conveying the 10-yr peak flow is to be placed at the location indicated on the drainage plan. The culvert is to be set with a minimum slope of 2.7%. Basin 5 Stormwater from this offsite area sheet flows to the south before entering Culvert 3 under the access road, into Basin 6 at Design Point 8. For the catchment area of 0.99 acres with an imperviousness of 10.84%, a channel capable of conveying a 100 -year peak flow of 0.45 cfs is required. To convey this stormwater under the proposed access road, culvert 3, a 12" culvert (Design Point 8) capable of conveying the 10-yr peak flow is to be placed at the location indicated on the drainage plan. The culvert is to be set with a minimum slope of 4.4%. Basin Stormwater from this offsite area sheet flows to the south in historical flow patterns before leaving the Basin 6. Basin 7 Stormwater from this offsite area sheet flows to the south and southwest according to historic drainage patterns. Runoff that enters Basin 7 from Basin 2 via offsite Diversion Channel 3 will return to sheet flow and mimic historic drainage patterns. Basin 8 Stormwater from this offsite area sheet to the south and southwest before entering Basin and 7. 2, 3, Final Drainage Report for ORCA Gathering Facility Pad Page 6 enern.us ASCENT GEOMATICS SOLUTIONS The owner is responsible for maintaining proper operation and access for all drainage facilities. The proposed detention features can be accessed from County Road 90, via the proposed access roads. Reclaimed portions of the disturbed area of the proposed site will be re -seeded. Any vegetation should be trimmed. Any debris or trash from the trash racks attached to the outlet structure should be cleaned. Any sediment from the rnicropool box should be cleaned out regularly. Any blockage in the culverts, swales, or outlet pipes should be removed to keep the drainage facilities at full capacity. 5. Conclusions The hydrologic and hydraulic calculations associated with the proposed drainage plan follow the Weld County Storm Drainage Criteria (WCSDC) and the Weld County Engineering and Construction Criteria (WCECC). These calculations show that the detention pond will detain the difference of developed 100 -year flow and the 5 -year historic release rate. The outlet structure is able to control water quality, detain the 100 -year storm, and release stormwater runoff at the 5 -year historic rate. The emergency spillway is able to release storm runoff at the 100 -year developed flow rate. Thus, the Weld County's stormwater requirements have been met and stormwater impacts due to proposed development have been mitigated.

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 (AID, BID, 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 (AID, BID, or CID), 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.

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 (AID, BID, 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 (AID, BID, or CID), 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.

Introduction Project Overview This traffic impact study addresses the capacity, geometric, and control requirements associated with the development entitled Enerplus Resources — Orca 8N67W26 Well Site. This proposed development consists of an Enerplus Resources salt water injection well site. The development is located near the southeast corner of the Weld County Road 90 and Weld County Road 19 intersection in Weld County, Colorado. Study Area Boundaries The study area to be examined in this analysis encompasses Weld County Road 90 east of Weld County Road 19. Figure 1 illustrates location of the site and study roadway. Site Description The proposed development is understood to entail the new construction of an Enerplus Resources salt water injection well site. Land for the development is currently vacant and surrounded by a mix of agricultural and open space land uses. Proposed access to the development is provided at the following location: One full -movement access road on Weld County Road 90 (referred to as Site Access). Site Access is existing and is an extension from Weld County Road 90 south approximately one mile. For purposes of this study, it is anticipated that development operations would be phased and be completed within a few months of development construction. A conceptual site plan, as prepared by Ascent Geomatics Solutions, is shown on Figure 2. This plan is provided for illustrative purposes.

A brief description of the roadway is provided below: Weld County Road 90 is an east -west, unpaved, rural local roadway having two through lanes (one lane in each direction). Weld County Road 90 does not provide a posted speed limit; however, based on County's Design Standardsl, Weld County Road 90 is assumed to have a speed limit of 55 MPH. No regional or specific improvements for Weld County Road 90 are known to be planned or committed at this time. I Weld County Engineering & Construction Criteria, Weld County' April 2012. SM ROCHA, LLC— Traffic and Transportation Consultants Page 4 Enerplus Resources — Orca 8N67W26 Well Site — Traffic Impact Study December 2018 II. Existing Traffic Conditions Average daily (24 -hour) traffic volumes were collected on Weld County Road 90 and include the directional morning (AM) and afternoon (PM) peak hour volumes. Counts also consider vehicle type based on size and number of axles. These counts are shown on Figure 3. Due to the nature and location of the development, no intersections were considered in this analysis. Traffic count data is included for reference in Appendix A. The Roadway Level of Service Analysis technique, as published in the Highway Capacity Manual (HCM) by the Transportation Research Board, was used to analyze the study roadway for existing traffic conditions. This nationally accepted technique allows for the determination of roadway level of service (LOS) based on the congestion and delay of each traffic movement. Level of service is a method of measurement used by transportation professionals to quantify a driver's perception of travel conditions that include travel time, number of stops, and total amount of stopped delay experienced on a roadway network. The H C M categorizes level of service into a range from "A" which indicates little, if any, vehicle delay, to "F" which indicates a level of operation considered unacceptable to most drivers. These levels of service grades with brief descriptions of the operating condition, for unsignalized and signalized intersections, are included for reference in Appendix B and have been used throughout this study. Table I summarizes roadway (arterial) level of service analysis results for existing conditions.

Future Traffic Conditions Without Proposed Development Background traffic is the traffic projected to be on area roadways without consideration of the proposed development. Background traffic includes traffic generated by development of vacant parcels in the area. Due to the nature of proposed development and its location within the County, no significant changes to existing traffic volumes are anticipated given the relatively short time of site operations mentioned in Section I. Additionally, no adjacent developments are known to be planned or committed within the immediate area which may impact traffic volumes. Therefore, no background traffic analysis was performed and changes to existing traffic volumes are expected to be caused by development site generated traffic only. SM ROCHA, LLC— Traffic and Transportation Consultants Page 7 Enerplus Resources — Orca 8N67W26 Well Site — Traffic Impact Study December 2018 IV. Proposed Project Traffic Trip Generation Traffic generation characteristics for the proposed development were estimated based on information provided by Enerplus Corporation as the Institute of Transportation Engineers (ITE) in their report entitled Trip Generation, I Oth Edition, do not provide accurate traffic generation information for a well site land use. As such, proposed facility operations were evaluated to estimate average daily trip generation. A vehicle trip is defined as a one-way vehicle movement from point of origin to point of destination. Trip generation estimates are given for two different phases of development. The summarized phases are as follows: 1. Facility Construction Phase — earthwork of site and general facility installations 2. SWD Construction Phase — salt water disposal well construction It should be noted that peak hour volumes were derived from standard relationships of ADT volumes versus peak hour volumes. Truck traffic generated throughout site development can vary based on numerous factors. Such factors include length of any access road being constructed, extent of site grading, and resource transportation methods including water delivery and oil or gas production. The trip generation estimates used in this study were selected to provide for a conservative analysis. It should also be noted that only site construction phases are considered as these phases are anticipated to be the highest periods of trip generation. Trip generation caused be development operations upon construction completion are considered to be minor with minimal impact to the surrounding roadway network. Trip generation estimates used in this study are presented in Table 2. SM ROCHA, LLC— Traffic and Transportation Consultants Page 8 Enerplus Resources — Orca 8N67W26 Well Site — Traffic Impact Study December 2018 Table 2 — Trip Generation Estimate PHASE OF DEVELOPMENT SIZE TOTAL TRIPS GENERATED HOUR 24 AM PEAK HOUR PM PEAK HOUR ENTER EXIT TOTAL ENTER EXIT TOTAL Facility Construction Phase 6 VEH 2 VEH 37 VEH 12 74 4 1 1 3 0 0 3 1 0 6 0 0 2 1 1 2 1 0 4 - - - Passenger Single Multiple Unit Unit Vehicle Truck Truck Construction Phase 'I Total: 90 5 3 7 2 4 4 SUD Construction Phase 12 14 50 VEH VEH VEH 100 24 28 1 1 4 1 1 4 2 2 8 1 1 5 1 2 5 2 3 10 - - - Passenger Single Multiple Unit Unit Vehicle Truck Truck Construction Phase 2 Total: 152 6 6 12 7 8 15 Note: All data and calculations above are subject to being rounded to nearest value. VEH = Vehicles. Passenger Vehicle = 4,500 to 8.500 lbs. Single Unit Truck = 10,000 to 20,000 lbs. Multiple Unit Truck = ≥ 50,000 lbs. As Table 2 shows, the proposed development has the potential to generate the following daily trips during each development phase: 1. Facility Construction Phase: 90 trips per day 2. SWD Construction Phase: 1 b2 trips per day Adjustments to Trip Generation Rates A development of this type is not likely to attract trips from within area land uses nor pass -by or diverted link trips from the adjacent roadway system, therefore no trip reduction was taken in this analysis. Trip Distribution The overall directional distribution of site -generated traffic was determined based on the location of the development site within the County, proposed and existing area land uses, and available roadway network. Overall trip distribution patterns for the development are shown on Figure 4. SM ROCHA, LLC— Traffic and Transportation Consultants Page 9 Enerplus Resources — Orca 8N67W26 Well Site — Traffic Impact Study December 2018 Trip Assignment Traffic assignment is how generated and distributed vehicle trips are expected to be loaded onto the available roadway network. Applying trip distribution patterns to the highest phase of site -traffic generation (SWD Construction Phase) provides the site -generated trip assignments shown on Figure 4 for analysis considerations. It should be noted that site -generated traffic volumes shown in Figure 4 represent total traffic volumes generated by the proposed development without including vehicle equivalence. Vehicle equivalence is based on the Colorado Department of Transportation (CDOT) vehicle equivalency definitions and is used for determining roadway service flow rates.

Future Traffic Conditions with Proposed Development Site -generated traffic was added to existing traffic volumes to determine total traffic conditions. For analysis purposes, total traffic conditions include trips generated by the SWD Construction Phase, the most conservative average daily trip generator between phases one and two as described in Section IV. Total traffic conditions were analyzed to determine the greatest potential impact caused by the proposed well site during the establishing phases of development. Impacts due to recurring traffic during the operational life -time of the well site are anticipated to be less than those caused during development construction and are considered to be minor. Pursuant to area roadway improvement discussions provided in Section I, total traffic conditions assume no roadway improvements to accommodate regional transportation demands. Roadway improvements associated with site development are expected to be limited to site access and frontage as required by the governing agency. Projected total traffic volumes are shown in Figure 5.

Project Impacts The analyses and procedures described in this study were performed in accordance with the Highway Capacity Manual (HCM) and are based upon the worst -case conditions that occur during a typical weekday. Therefore, study roadways are likely to operate with traffic conditions better than those described within this study, which represent the peak hours of weekday operations only. Peak Hour Intersection Levels of Service Total traffic level of service analysis results are summarized in Table 3. As previously mentioned, total traffic conditions consider build -out of the SWD Construction Phase, the most conservative trip generator between phases one and two as described in Section IV. Definitions of levels of service are given in Appendix B.

A maximum service flow of approximately 27 total passenger car equivalent vehicles is anticipated occurring within the PM peak traffic period. SM ROCHA, LLC— Traffic and Transportation Consultants Page 14 Enerplus Resources — Orca 8N67W26 Well Site — Traffic Impact Study December 2018 VII. Conclusion This traffic impact study addressed the capacity, geometric, and control requirements associated with the development entitled Enerplus Resources — Orca 8N67W26 Well Site. This proposed development consists of an Enerplus Resources salt water injection well site. The development is located near the southeast corner of the Weld County Road 90 and Weld County Road 19 intersection in Weld County, Colorado. The study area to be examined in this analysis encompasses Weld County Road 90 east of Weld County Road 19. Analysis was conducted for critical AM Peak Hour and PM Peak Hour traffic operations for existing traffic conditions, and total traffic conditions. Due to the nature of the proposed business and its location within the City, background traffic analysis was not accounted for. Analysis of existing conditions indicates that Weld County Road 90 operates at LOS A during both the morning and afternoon peak traffic hours. Analysis of future traffic conditions indicates that the addition of site -generated traffic is expected to create no negative impact to traffic operations for the existing and surrounding roadway system. With all conservative assumptions defined within this analysis, the study roadway is projected to operate at future levels of service comparable to existing traffic conditions.

Automobile Level of Service (LOS) for Signalized Intersections Levels of service are defined to represent reasonable ranges in control delay. LOS A Describes operations with a control delay of lOs/veh or less and a volume -to -capacity ratio no greater than 1.0. This level is typically assigned when the volume -to -capacity ratio is low and either progression is exceptionally favorable or the cycle length is very short. If it is due to favorable progression, most vehicles arrive during the green indication and travel through the intersection without stopping. LOSB Describes operations with control delay between 10 and 20 s/veh and a volume -to -capacity ratio no greater than 1.0. This level is typically assigned when the volume -to -capacity ratio is low and either progression is highly favorable or the cycle length is short. More vehicles stop than with LOS A. LOSC Describes operations with control delay between 20 and 35 slveh and a volume -to -capacity ratio no greater than 1.0. This level is typically assigned when progression is favorable or the cycle length is moderate. Individual cycle failures (i.e., one or more queued vehicles are not able to depart as a result of insufficient capacity during the cycle) may begin to appear at this level. The number of vehicles stopping is significant, although many vehicles still pass through the intersection without stopping. LOS D Describes operations with control delay between 35 and 55 slveh and a volume -to -capacity ratio no greater than 1.0. This level is typically assigned when the volume -to -capacity ratio is high and either progression is ineffective or the cycle length is long. Many vehicles stop and individual cycle failures are noticeable. LOS E Describes operations with control delay between 55 and 80 s&veh and a volume -to -capacity ratio no greater than 1.0. This level is typically assigned when the volume -to -capacity ratio is high, progression is unfavorable, and the cycle length is long. Individual cycle failures are frequent. LOS F Describes operations with control delay exceeding 80 slveh or a volume -to -capacity ratio greater than 1.0. This level is typically assigned when the volume -to -capacity ratio is very high, progression is very poor, and the cycle length is long. Most cycles fail to clear the queue.

The project is located in the Southwest Quarter of Section 26, Township 8 North, Range 67 West. The approximate coordinates are: Latitude — 40.62698 N Longitude —104.86771 W. Please advise. I will follow up with an additional phone call to discuss with you tomorrow, the 18th. Thank you for your time.
