If a corporation is the fee owner, notarized evidence must be included indicating that the signatory has to legal authority to sign for the corporation. Signature: Owner or Authorized Agent Date Signature: Owner or Authorized Agent Date 1. Explain, in detail, the proposed use of the property. Whiting Oil and Gas is proposing a produced water injection facility in the A (Agricultural) Zone District on a 312.129 acre parcel located in the South 1/2 of Section 19, Township 10 North, Range 57 West, 6th P.M., Weld County, Colorado. This facility will handle only Whiting Oil and Gas produced water and will not operate as a commercial facility. The water that is brought to this facility is from the surrounding vicinity. This water will be delivered to the location primarily by pipeline; however, the ability to truck water is also proposed. The site is accessed from an existing lease road. From the intersection of CR 116 and CR 133, a lease road is accessed going south about 1 mile, then left (east) to the disposal location. The vicinity map shows the proposed water injection facility location as it relates to county roads. This facility is anticipated to operate twenty four hours per day, seven days a week. Whiting Oil and Gas is concurrently submitting a subdivision exemption application for the land that is being leased from RIM Land Company LLC, where this facility will be constructed. The land that this disposal well sits on has already been cleared, and a well has already been drilled for micro-seismic monitoring. The facilities for this well are on the location. The facility is anticipated to be unmanned other than routine maintenance being done on the facility. The expected flow into this facility is up to 15,000 barrels per day and is expected to reach this flow very shortly after being put into service if not immediately. As stated, the majority of this volume will be piped in, eliminating the need for approximately 50 trucks daily that are currently traveling great distances on Weld county roads to commercial injection wells. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive plan. With the development and use of the saltwater disposal well, it will provide the most efficient means of transportation. Sec 22-5-90, subsection C, states that the most efficient and environmentally friendly way to transport product is by pipeline, rather than by truck. The well will eliminate the need for approximately 50 water trucks per day, which will reduce the consumption of resources, damages to the road and road congestion, and help with the mitigation of dust. This also supports Sec 22-3-60, Transportation Goals and Policies and the goal of considering alternative modes of transportation, and reducing the overall Vehicle Miles Traveled (VMT) 3. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 23 (Zoning) and the zone district in which it is located. With the development and use of the saltwater disposal well, it will provide the most efficient means of transportation. Sec 23-1-40, Purpose and Intent, paragraph A, subsection 1, is met with the reduction of congestion on the streets and roads or reducing the waste caused by excessive amounts of road use. 4. What type of uses surround the site (explain how the proposed use is consistent and compatible with surrounding land uses). Surrounding the proposed location of the saltwater disposal well are oil production facilities to support overall production of oil and natural gas. The location of the wells were also discussed and approved by the landowner, through the use of a Surface Use Agreement. No residential homes are located near or are visible to this location. 5. Describe, in detail, the following: a. Number of people who will use this site. These sites will be unmanned and the primary method of water delivery will be by pipeline. Traffic associated with this disposal well will be minimal and will include up to five visits per day by a pickup truck to do routine maintenance and inspections. The facility is being built to accommodate up to 50 water trucks daily; however, the expectation is that the facility will see an average of 10 water trucks daily under normal operating conditions. The few water trucks that will visit this site will be travelling many fewer miles on county roads than they otherwise would without this facility. b. Number of employees who will use this site. The site will be unmanned and the well will be monitored remotely. c. Hours of operation. Twenty four hours a day, seven days a week. d. Type and number of structures to be built on this site. • Up to twenty four 750 BBL tanks. • Up to 21,000 BBL tanks. • Up to 4 400 BBL tanks. • One Separator. • One Enclosed Pump Skid. • One Power Distribution Building. • One Truck Unloading Skid. • One Data Controls Building with remote monitoring. • One communications tower. • One disposal wellhead. e. Type and number of animals, if any, to be on this site There will be no animals housed on the site. f. Kind of vehicles (type, size, weight) that will access this site and how often. Trucks that will access the site include 18-wheeler water haul trucks with a capacity of 190 BBLs. These trucks will access the site an average of 10 times per day. In addition, 4-wheel drive pickup vehicles will access the site for maintenance and inspections, with no more than 5 visits per day. g. Who will provide fire protection to the site? The property falls within the New Raymer — Stoneham Fire Protection District h. Water source on the property (both domestic and irrigations). There is no existing water source (domestic or irrigation), on the property. Bottled water for human consumption will be provided during construction. i. Sewage disposal system on the property (existing and proposed). There is no existing sewage disposal system on the property. Portable toilets will be provided during construction and once the site is operating. There are no plans to permit for a sewage disposal system. j. If storage or warehousing is proposed, what type of items will be stored? No storage or warehousing is proposed for this site. 6. Explain the proposed landscaping for the site. There are no neighbors around the site to require screening and there is no irrigation to the site to support landscaping; therefore, no landscaping is proposed. The native vegetation around the site will remain. 7. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. When termination of the facility occurs, the facilities will be removed and the land will be returned to its native state including its natural terrain as well as reseeded with native vegetation. 8. Explain how the storm water drainage will be handled on the site. The natural terrain and drainage of this site slopes from northwest to the southeast, with a slope range of 0-6%. The location being applied for an USR is 4.887 acres on an approximately 312.129 acre parcel. Whiting Oil and Gas has included in the application a professional engineered stamped conceptual drainage report to support the USR process. A water quality feature has also been added to the plats. 9. Explain how long it will take to construct this site and when construction and landscaping is scheduled to begin. Whiting Oil and Gas anticipates that it will take three months to construct the site. No landscaping is proposed for the site. The native vegetation around the site will remain. 10. Explain where storage and/or stockpiles of wastes that will occur on this site. There will be no storage and/or stockpiles of wastes on this site. 11. Please list all proposed on-site and off-site improvements associated with the use (example: landscaping, fencing, drainage, turn lanes, etc.) and a timeline of when you will have each one of the improvements completed. There will be no improvements to the landscaping. Surrounding the proposed well are other wells, which have already been permitted. A fence will be constructed around the well on Horsetail 19 N pad. This improvement will be completed during the anticipated three month construction period. The natural terrain of this site slopes from northwest to the southeast, with a slope range of 0-6%. The location being applied for an USR is 4.887 acres on an approximately 312.129 acre parcel. Whiting Oil and Gas has included in the application a professional engineered stamped conceptual drainage report to support the USR process. A water quality feature has also been added to the plats. Drainage Report The location being applied for an USR is 4.887 acres on an approximately 312.129 acre parcel. Whiting Oil and Gas has included in this application a professional engineered stamped conceptual drainage report. Please refer to the attached Conceptual Drainage Report for Horsetail 19N-1924M Pad, dated January 28, 2015, for specific drainage details. Traffic Narrative Trucks that will access the site include 18-wheeler water haul trucks with a capacity of 190 barrels. These trucks will access the site an average of 10 times per day. In addition, 4-wheel drive pickup vehicles will access the site for maintenance and inspections, with no more than 5 visits per day. As this site will be operational 24 hours a day and is generally an unmanned facility, there are no peak traffic hours when more water hauling vehicles would be expected to access or use the site. The pickup truck visits, approximately 5 per day, will generally be during normal business hours between 6 AM and 4 PM. All vehicles are expected to access this site via a lease road that begins at the intersection of CR 116 and CR 133 (Access Permit # AP11-00363). During operation the of this facility, most of the traffic, approximately 75%, is expected to access the site from CR 133 to the south, and the remainder is expected to access the site from CR 116 to the east. Whiting Oil and Gas will agree to improvement triggers as required by Weld County of: - 200 vpd or significant dust as identified by County-Mag-Chloride dust abatement - 300 vpd alternative pavement - 400 vpd pavement - 10 vph during peak hour turning left into the facility-left deceleration lane - 25 vph during peak hour turning right into the facility-right deceleration lane - 50 vph during peak hour turning right out of the facility-right accelerat on lane Waste Handling Plan The location will be unmanned, so there will be no trash service at this saltwater disposal well location during operation. Employees and contract truck drivers will be responsible for taking any trash generated onsite to a location with waste handling capabilities. During construction, a trash dumpster will be provided on-site. Whiting Oil and Gas preferred trash service is Wolf Waste Removal. The only wastes to be handled on this site are water and trace amounts of oil. The water will be disposed of in the injection well. The oil will be separated from the water and held in four onsite oil tanks. This oil will be removed from the site via truck initially, with the possibility of adding a pipeline to move the oil off the site at a later date. Whiting Oil and Gas has multiple oil trucking companies on contract in the area and will likely utilize multiple companies to truck the oil. Scale inhibitor is the only chemical planned to be stored onsite. Whiting Oil and Gas would keep no more than 500 gallons onsite at any given time. These chemicals would be stored in a tank and would either be located in a building with a sump or be contained within a secondary containment of corrugated steel with a liner. The location will depend on where they will be most effective. The purpose of these chemicals is to treat the water to extend equipment life. The chemicals will not need to be disposed of offsite as they will be added to the water in trace amounts to perform their function. Tank bottoms will be cleaned as needed, which Whiting Oil and Gas anticipates to be approximately once per year. They will be cleaned by draining the tanks, injecting hot water into the tanks to mix up the solids and re-draining the tanks. Waste Management is the company Whiting Oil and Gas anticipates using for removal/disposal. Closure Plan Once this well is no longer in operation, the proper steps will be taken to return this site to its native state. This will include plugging and abandoning the well according to current regulations, removing all equipment to approved locations, bringing the land back to its original slope, and planting native grasses to re-vegetate the location. Horsetail 19 N Water Injection Facility Dust Abatement Plan • During construction, a water truck will be utilized to control dust. • The access road and facility pad will consist of gravel road base. Since traffic to the site will be sparse and at various times of day, dust will primarily be controlled by limiting speed of vehicles on the site. If for any reason the traffic to the s to is expected to be heavier than normal, water trucks will be utilized to control dust. Air Pollutant Emission Notice A copy of the Air Pollutant Emission Notice (APEN) that is submitted to the Colorado Department of Public Health and Environment (CDPHE) will be sent to the Weld County Department of Public Health and Environment when it becomes available . This site is an APEN reportable site but will not reach any APEN permitting thresholds. A copy of the APEN report will be provided when it become available. Ground Water Monitoring Plan To ensure the integrity of groundwater, Whiting Oil and Gas will construct a SWD well with numerous barriers of protection: Whiting will run a string of 9-5/8" steel casing to approximately 1600' and cement the casing to surface; In addition, Whiting will run a string of 7" casing to approximately 8300' (the total depth of the well) and will cement the casing to surface; Finally, Whiting will run a string of 3- 1/2" internally coated injection tubing inside of the 7" casing with a packer, which is a device that provides and additional pressure seal inside the weilbore. A Cement Bond Log (CBL) will be run to evaluate and ensure the cement behind the casing is capable of providing a pressure and mechanical barrier — engineers and regulators at the COGCC will verify the cement quality is adequate. Whiting's proposed disposal zones are between 7000' and 8200', which is even deeper than the Niobrara formation, from which oil and gas are currently being extracted. The three (3) strings of steel tubulars, in conjunction with 2 layers of cement, will ensure protection of groundwater from the water being injected into the deeper formations. An initial pressure test will be performed on the casing, tubing and packer per the Colorado Oil and Gas Conservation Commission (COGCCC) regulations to ensure the welibore is competent (otherwise known as a Mechanical Integrity Test, or MIT), and will be witnessed by a COGCC official. By law, Whiting will comply with a maximum injection pressure and maximum injection rate, also set and regulated by the COGCC. Monthly injection pressure and rate records will be kept and submitted to the COGCC. Daily monitoring will be performed to ensure the wellhead and all surface equipment is functioning properly. Automation equipment will be installed for an added safety feature to shut-down operations if any major component should malfunction. Finally, Whiting will perform Mechanical Integrity Tests every five (5) years to prove wellbore integrity, to be witnessed by a COGCC official. If at any time wellbore integrity is in quest on, Whiting will cease injection operations and restore integrity to the weilbore.

This report is prepared in accordance to the Weld County Engineering and Construction Criteria (WCECC), Weld County Ordinance 2008-9 and Urban Storm Drainage Criteria Manual (USDCM). The proposed site collects runoff from the pad and diverts it through a water quality feature in accordance with the WCECC and USDCM in the southeast corner of the site. Therefore, the construction of the proposed Horsetail 19N- 1924M Pad development is in compliance with both the Weld County and UDFCD stormwater criteria. We look forward to your consideration and feedback of this Conceptual Drainage Report.

General Location and Description 1 . 1 . Location The Horsetail 19N-1924M Pad is located in the south quarter of Section 19, Township 10 North , Range 57 West of the 6th Principal Meridian , Weld County, Colorado. It is physically located about 1 mile southeast of the intersection of Weld County Road (CR) 116 and Weld County Road (CR) 133. The proposed site is bounded by agricultural land to the north , east, south , and west (please see the Vicinity Map in Appendix A). There are no water resource facilities within or adjacent to the proposed site. Surrounding development includes two pads north of CR 116 and a residential lot west of HWY 114. The two pads are located 4500 ft. north of the proposed site. The residential lot is located 4800 ft. northwest of proposed site. 1 .2. Description of the Property The proposed site is owned by Whiting Petroleum Corporation with an intention to develop in two phases. The original 4 .887 acres of land purchased for this development was split into Phase I and Phase II . Phase I of the site is a well pad that was developed on the west half of the site, consisting of one well . There are also existing dirt piles to the east the well pad for Phase I development. An existing access road is located on the southwest side of the well pad and connects to HWY 114 through an existing 2-track dirt road . Phase II development includes an additional well , swales, and a detention pond . Swales are proposed to the north , south , and west of the site. The detention pond is proposed in the southeast corner of the site, which is sized to accommodate runoff from the Phase I & II developments. Prior to development, the proposed 4.887 acre site (Phase I & II ) was used in an agricultural capacity. As determined by the USDA Web Soil Survey, the historical soils are Kim-Mitchell complex. The Hydrologic Soil property is Hydrologic Type C. (Please see the Hydrologic Soils Map in Appendix A. ) The historical site generally slopes from the northwest to the southeast at a range of 0% to 6% slope. The percent imperviousness for the historical site is 2% . Upon Phase and Phase II development, the proposed site will be a mix of native planted areas and compacted gravel . The composite percent imperviousness will increase. The site is located approximately 2800 feet northwest of a livestock water pond . There are no major drainage or irrigation facilities across the site or within 200 feet of the site.

Major Basin Description There is no comprehensive drainage plan associated with the proposed site and no irrigation facilities are located within 200 feet of the proposed site. As indicated from the Weld County FEMA Map Indexes, the proposed site is within Panel ID 08123C0825E (Preliminary FIRM Map), which was not printed . Thus, there is no FIRM Map associated with the proposed site. 2 .2 . Sub-Basin Description There is one basin for the proposed development. Basin 1 is delineated to include Phase I and Phase II development. Stormwater historically drains from the northwest to the southeast. On- site stormwater follows a similar drainage pattern and drains from the northwest corner to the southeast corner. There are no developed properties southwest of the site. Stormwater discharged from the southeast corner of the site continues the historical drainage pattern and flows to the southeast. Offsite stormwater also follows a similar drainage pattern and drains to the proposed site from the north and the west. 3 . Drainage Facility Design 3 . 1 . General Proposed Concept The proposed drainage plan follows a similar drainage pattern as the historic path . The site will be graded to drain a majority of the site to the southeast to a proposed water quality feature via the south swales. Offsite stormwater from the northwest follows the historical drainage pattern and sheet flows across the site. This will be collected by proposed diversion swales located to the north and west of the proposed site and continue to flow offsite. Since the proposed project consists of 4.88 acres of gravel covered pad from a parent parcel of 629.559 acres the post development imperviousness will be 2. 14% which is less than 10% so no stormwater detention is required per Weld County Ordinance 2008-9 "No stormwater detention shall be required for rural residential developments of nine (9) lots or fewer, where the average lot size is equal to or greater than three (3) acres per lot and : 1 ) downstream roadway criteria are not exceeded (6-inches water depth on road for the 10-year storm); and 2) the total post-development imperviousness for the rural residential development does not exceed ten Conceptual Drainage Report for Horsetail 19N-1924M Pad Page 2 l, l WHITING PFS81. VPr_hoteum Field Services percent ( 10%), assuming that all internal roads and driveways are paved (or eventually will be paved )." Water quality will be incorporated into the pad at a volume of 2,050 cubic feet. See Appendix A for all water quality and imperviousness calculations 3 .2. Specific Details This proposed drainage plan follows the Weld County Engineering and Construction Criteria (WCECC) and follows the suggested methods for Water Quality Feature Procedure as shown in Appendix A. This procedure is based off of the Urban Drainage Criteria Manual V3. The results of the calculations indicate a required storage volume of 0.77 ac ft (33, 747 cu ft) for the site. The proposed water quality feature will be 115' x 100' at 3' deep which is shown on the Conceptual Drainage Plan in Appendix A. Site grading shall be implemented to conform to this report.

This report is prepared in accordance to the Weld County Engineering and Construction Criteria (WCECC) and Urban Storm Drainage Criteria Manual (USDCM). The proposed site collects 100-year developed flows and releases at the historic 5-year rate. In addition, the outlet structure incorporates water quality measures in accordance with the WCECC and USDCM. Therefore, the construction of the proposed Horsetail 19N-1924M Pad development is in compliance with both the Weld County and UDFCD stormwater criteria. We look forward to your consideration and feedback of this Conceptual Drainage Report. if you have any further questions or comment, please contact our office at 303-928-7128 or by email at mwelkerpetro-fs.com.

General Location and Description 1 . 1 . Location The Horsetail 19N-1924M Pad is located in the south quarter of Section 19, Township 10 North , Range 57 West of the 6th Principal Meridian , Weld County, Colorado. It is physically located about 1 mile southeast of the intersection of Weld County Road (CR) 116 and Weld County Road (CR) 133. The proposed site is bounded by agricultural land to the north, east, south , and west (please see the Vicinity Map in Appendix A). There are no water resource facilities within or adjacent to the proposed site. Surrounding development includes two pads north of CR 116 and a residential lot west of HWY 114. The two pads are located 4500 ft. north of the proposed site. The residential lot is located 4800 ft. northwest of proposed site. 1 .2. Description of the Property The proposed site is owned by Whiting Petroleum Corporation with an intention to develop in two phases. The original 4 .887 acres of land purchased for this development was split into Phase I and Phase II . Phase I of the site is a well pad that was developed on the west half of the site, consisting of one well . There are also existing dirt piles to the east the well pad for Phase I development. An existing access road is located on the southwest side of the well pad and connects to HWY 114 through an existing 2-track dirt road . Phase II development includes an additional well , swales, and a detention pond . Swales are proposed to the north , south, and west of the site. The detention pond is proposed in the southeast corner of the site, which is sized to accommodate runoff from the Phase I & II developments. Prior to development, the proposed 4.887 acre site (Phase I & II ) was used in an agricultural capacity. As determined by the USDA Web Soil Survey, the historical soils are Kim-Mitchell complex. The Hydrologic Soil property is Hydrologic Type C. (Please see the Hydrologic Soils Map in Appendix A. ) The historical site generally slopes from the northwest to the southeast at a range of 0% to 6% slope. The percent imperviousness for the historical site is 2% . Upon Phase and Phase II development, the proposed site will be a mix of native planted areas and compacted gravel . The composite percent imperviousness will increase. The site is located approximately 2800 feet northwest of a livestock water pond . There are no major drainage or irrigation facilities across the site or within 200 feet of the site. Conceptual Drainage Report for Horsetail 19N-1924M Pad Page 1 l, l )L WHITING PFS1 / 4 uc Nay Petroleum Field Services 2 . Drainage Basins and Sub-Basins 2. 1 . Major Basin Description There is no comprehensive drainage plan associated with the proposed site and no irrigation facilities are located within 200 feet of the proposed site. As indicated from the Weld County FEMA Map Indexes, the proposed site is within Panel ID 08123C0825E (Preliminary FIRM Map), which was not printed . Thus, there is no FIRM Map associated with the proposed site. 2 .2 . Sub-Basin Description There is one basin for the proposed development. Basin 1 is delineated to include Phase I and Phase II development. Stormwater historically drains from the northwest to the southeast. On- site stormwater follows a similar drainage pattern and drains from the northwest corner to the southeast corner. There are no developed properties southwest of the site. Stormwater discharged from the southeast corner of the site continues the historical drainage pattern and flows to the southeast. Offsite stormwater also follows a similar drainage pattern and drains to the proposed site from the north and the west. 3 . Drainage Facility Design 3 . 1 . General Proposed Concept The proposed drainage plan follows a similar drainage pattern as the historic path . The site will be graded to drain a majority of the site to the southeast to a proposed water quality feature via the south swales. Offsite stormwater from the northwest follows the historical drainage pattern and sheet flows across the site. This will be collected by proposed diversion swales located to the north and west of the proposed site and continue to flow offsite. An outlet structure and emergency spillway will be proposed at the south end of the detention pond to convey flows offsite. Water quality will be incorporated in the outlet structure and a micropool box is proposed to control the sedimentation . Conceptual Drainage Report for Horsetail 19N-1924M Pad Page 2 l, l )L WHITING PFS1 / 4 1% uc Petroleum Field Services 3 .2 . Specific Details This proposed drainage plan follows the Weld County Engineering and Construction Criteria (WCECC) and follows the suggested methods for Water Quality Feature Procedure as shown in Appendix A. This procedure is based off of the Urban Drainage Criteria Manual V3. The results of the calculations indicate a required storage volume of 0.77 ac ft (33,747 cu ft) for the site. The proposed water quality feature will be 115' x 100' at 3' deep which is shown on the Conceptual Drainage Plan in Appendix A. Site grading shall be implemented to conform to this report.
