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 308.85 acre parcel located in the southeast quarter of Section 16, Township 9 North, Range 59 West. 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 110 and CR 119, go south to CR 104. Turn west on CR 104 to the lease road entrance, turn right (north) to the well site. 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 Wade E. Castor and Deland Todd Castor, where this facility will be constructed. The land that this disposal well sits on has already been cleared as it is drilled adjacent to wells that are producing oil and gas from the Niobrara formation. The facilities for this well are on land just northwest of the disposal well and this location has not yet been cleared. 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 wells, 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 this 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 lessening of congestion in 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 2 1,000 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 ite. 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 of this site slopes from the southeast to the northwest, with slopes ranging from 0 - 9%. The location being applied for an USR is 9.795 acres on an approximately 308.85 acre parcel. Whiting Oil and Gas has included in the application a professional engineered stamped final 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 Wildhorse 16 L pad. This improvement will be completed during the anticipated three month construction period. The natural terrain of this site slopes from the southeast to the northwest, with slopes ranging from 0 - 9%. The location being applied for an USR is 9.795 acres on an approximately 308.85 acre parcel. Whiting Oil and Gas has included in the application a professional engineered stamped final 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 9.795 acres on an approximately 308.85 acre parcel. Whiting Oil and Gas has included in this application a professional engineered stamped final drainage report. Please refer to the attached Final Drainage Report for Wildhorse 16 SWD Injection Facility, 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 from CR 104 (Access Permit# AP10-00136). During operation of this facility, most of the traffic, approximately 75%, is expected to be accessing the site from CR 104 from the east and the remainder is expected to access the site from CR 104 from the west. 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 acceleration 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's 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 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 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 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. Wildhorse 16 L 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 the day, dust will primarily be controlled by limiting the speed of vehicles on the site. If for any reason the traffic to the site 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. Groundwater Monitoring Plan To ensure the integrity of groundwater, Whiting 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 an additional pressure seal ins de the wellbore. A Cement Bond Log (CBL) will be run to evaluate and ensure the cement behind the casin::- 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 wellbore 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 question, Whiting will cease injection operations and restore integrity to the wellbore.

General Location and Description 1 . 1 . Location The Wildhorse 16 SWD Injection Facility is located in the Northwest IA of the Southwest 1/4 of Section 16, Township 9 North , Range 59 West of the 6th Principal Meridian , Weld County, Colorado. It is physically located about 1 miles northwest of the intersection of Weld County Road (CR) 115 and Weld County Road (CR) 104 (see Vicinity Map in Appendix A for exact location). The site is located within the Pawnee National Grasslands and consists of agricultural rangeland . There is one well pad located directly south of the proposed facility. 1 .2 . Description of the Property The proposed site is 9.795 acres in area and owned by Whiting Petroleum Corporation . This site is developed in two construction phases: Phase I and Phase II . Phase I consists of a graded well pad that makes up the southeast portion of the site. This well pad consists of 2 wells, 4 oil tanks, a pump building , a propane tank, a flare stack, and a burner. There is also an existing buried pipeline located east of the well heads that runs north-south and an existing topsoil stockpile located along the south edge of the pad. Phase II of the site is a proposed production facility pad and makes up the northwest portion of the property. This portion consists of 4 proposed tank pads - one containing 12 filtered water tanks, one containing 14 working water tanks, one containing two oil tanks, and one containing water tanks - as well as a proposed pump building . Drainage facilities, including a detention pond , an emergency spillway, and outlet structures are proposed to the north of the proposed production facility pad . Swales are also proposed on the southwest and northeast of the site to drain offsite and onsite stormwater. As determined by the USDA Web Soil Survey, the historical soils on this site are Epping silt loam , Olney fine sandy loam and Otero sandy loam . The hydrologic soil property is a combination of hydrologic type A (32%), type B (23%) and type D (45%) (see Hydrologic Soils Map in Appendix A). The historical site generally slopes from the southeast to the northwest with slopes ranging from 0 to 9%. The percent imperviousness for the historical site is 2% . Upon completion of phase II development the proposed site will be a combination of native planted areas, compacted gravel, concrete pads and buildings. The composite percent imperviousness will be 33. 00% (please see calculations in Appendix B for details). Final Drainage Report for Wildhorse 16 SWD Injection Facility Page 3 I1 WHITING PFSNse Petroleum Field Services 2 . Drainage Basins and Sub-Basins 2 . 1 . Major Basin Description There is no Weld County Master Drainage Plan associated with the proposed site and there are no irrigation facilities located within 200 feet of the site. As indicated by the Weld County FEMA Map Index, the proposed site is within Panel ID 08123C0800E (Preliminary FIRM Map), which was not printed . Thus, there is no FIRM Map associated with the proposed site. 2 .2 . Sub-Basin Description Stormwater historically drains from the southeast to the northwest of the site. Developed on site stormwater follows a similar drainage pattern and drains from the southeast to the northwest as well . A single drainage basin was delineated within the proposed site. Runoff from the southeast well pad flows to the northwest corner, is collected via proposed swales, and drains to the proposed detention pond . Runoff from the northwest production facility pad also drains to the proposed detention pond from the southeast through swales located to the east and west. Offsite stormwater to the north and west of the site will follow the historical drainage pattern and naturally flow away from the site. Offsite stormwater coming from the southeast will partially drain to the proposed detention pond and partially flow away from the site. Offsite stormwater from the south will be picked up by a roadside ditch from an existing access road . 3 . Drainage Design Criteria 3 . 1 . Development Criteria Reference and Constraints There is no Weld County Master Drainage Plan associated with the proposed site. The composite percent imperviousness for the developed area will increase because of additions of gravel and small structures. A majority of the area will be graded to drain to the northwest, then through swales into a proposed detention pond (please see Appendix D for details). There is an existing pipeline corridor running in a north-south direction in the east half the well pad . This buried pipeline limits the extent of the proposed swales. In addition , there is an existing stockpile located south of the well pad . Swales will be required to convey stormwater developed from the stockpiles. Final Drainage Report for Wildhorse 16 SWD Injection Facility Page 4 I1 WHITING PFSNse Petroleum Field Services 3 .2 . Hydrological Criteria This proposed drainage plan follows 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 indicated in the NOAA Atlas in Appendix A, the associated one hour point rainfalls are 1 .57 inches and 2 .76 inches respectively. As the on-site basin is less than 160 acres ( 11 . 77 acres), the rational method was used to compute the runoff. The weighted percent imperviousness and runoff coefficient were calculated for Basin 1 and Basin 2 for the proposed development per WCECC Table 5-3 and USDCM RO- 4, and Equations RO-6 and RO-7. The time of concentration was calculated using USDCM Table RO-2 and Equation RO-2 , RO-3, RO-4, and RO-5. As noted in WCECC, the detention pond is sized by the difference between 100-year fully developed runoff rate and historic 5-year release rate. The storage volume of the detention pond was computed by the Modified FAA Method using UDFCD UD-Denteion_v2 .34 Spreadsheet. Please see Hydrological Computations in Appendix B for details. 3 .3 . Hydraulic Criteria The hydraulic structure proposed on-site includes one detention pond , outlet structure, and emergency spillway. The outlet structures of the detention pond were computed using the UDFCD UD- Denteion_v2.34 Spreadsheet. These hydraulic calculations include Stage Storage Sizing for Detention Basins, Stage-Discharge Sizing of the Water Quality Capture Volume (WQCV) 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 drain time. The Water Quality trash screen size and trash rack over the outlet were calculated per USDCM V3 Chapter 4 Outlet Structure. Please see Hydraulic Computations in Appendix C for details. 4. Drainage Facility Design 4. 1 . General Concept The proposed drainage plan follows a similar drainage pattern as the historic path . For the proposed production facility pad , the site will be graded to drain a majority of the site to the Final Drainage Report for Wildhorse 16 SWD Injection Facility Page 5 I1 WHITING PFS Petroleum Field Services proposed detention pond located in the northwest. Stormwater from the well pad will be conveyed via swales to the proposed detention pond . An outlet structure and emergency spillway will be constructed at the northwest end of the detention pond to convey flows offsite. Water quality is incorporated in the outlet structure and a micropool box is proposed to control the sedimentation . 4.2 . Specific Details The depth of the proposed detention pond is 5.0 ft. as the top of the pond is 5037.0 and the invert of the outlet pipe is 5032.0. The proposed detention pond has a calculated storage volume of 1 .69 acre-ft. The proposed detention pond is graded with a 4: 1 interior side slope and provides 1 foot of freeboard above the developed 100-year water surface elevation . The associated outlet structure includes a micropool box with water quality plate, restrictor plate, and one 18-in outlet pipe. The diameter of the holes in the water quality plate is 0.917 inch . An emergency spillway, which is designed to provide failure protection for the embankment in the event the outlet is clogged, is designed with 4: 1 side slopes and a length of 30 feet. The owner is responsible for maintaining the operation and access of the drainage facilities. The proposed detention pond can be accessed from CR 104, and on-site access roads. The disturbed area of the revised pond will be re-seeded . Any vegetation should be trimmed . Any debris or trash from the trash grates attached to the outlet structure should be cleaned. Any sediment from the micropool box should be cleaned out regularly. Any blockage in the culverts, ditches, or outlet pipes should be removed to keep the drainage facilities at full capacity. 5. Conclusion The hydrologic and hydraulic calculations associated with the proposed drainage plan follow the Weld County Engineering and Construction Criteria (WCECC) and Urban Storm Drainage Criteria Manual (USDCM ). 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 stormwater, 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, Weld County's stormwater requirements have been met and stormwater impacts due to proposed development have been mitigated.

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