More specifically the property is located approximately 8,000 feet west of the intersection of Weld County Road (WCR) 74 and WCR 105. This is approximately 14 miles southwest of New Raymer. The following questions are to be answered and submitted as part of the USR application. If a question does not pertain to your use, please respond with "not applicable",with an explanation as to why the question is not applicable. 1. Explain, in detail,the proposed use of the property. The proposed Use by Special Review is for a well water storage and a water load-out facility. The property contains an 80,000 barrel capacity reservoir with three (3) truck filling bays.The reservoir is filled by an existing on-site water well. The non-potable water is used to support oil and gas operations including drilling and hydraulic fracturing. The facility is operated by Select Energy Services and is used to provide water for oil and gas operations on the Weitzel Ranch and surrounding areas. The facility will encumber approximately 10.8+/-acres of a larger 80 acre parcel. For projects located within the Weitzel ranch, water can be piped from the reservoir using ten (10) inch Victaulic pipe that can span distances up to 14 miles from the reservoir. Through the use of piping, the volume of truck traffic on county roads is greatly reduced. For surrounding projects not located within the ranch boundary, water will be trucked off-site. Trucks will enter the property using the existing access road, load water at the filling bay and then exit the property. The facility does not have daily operations such as a permanent office or maintenance facilities. The site will be accessed by truck drivers picking up water, by employees checking on the facility to ensure that the facility is within good working condition or by a pipe laying crew installing piping and plumbing for a specific project. Since the site does not have permanent facilities, it is not envisioned that the site would have enhanced landscaping. The site is located within a ranch and fenced from cattle so areas disturbed will be re-seeded with native grasses. Additionally, the site will not have permanent signage, parking spaces, or lighting. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. The Weitzel Sec 33 Water Facility is consistent with Section 22-2-10 Agriculture and Section 22-2-20 Agriculture goals and policies, of Chapter 22 of the Weld County Code. The property is currently zoned agriculture, A. This facility preserves the existing rangeland of the property yet incorporates a much needed support service for the oil and gas industry. Weld County's Comprehensive plan recognizes that agriculture and extraction of natural resources are vital to the County's economy.The project Lamp, Rynearson&Associates, Inc. Page 1 Project No.0212010.00 MSS positively supports mineral extraction within agriculture lands by minimizing impacts to County's roads by reducing the number of trucks trips and reducing the number of miles driven by the trucks. 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 As previously noted,the Weitzel Sec 33 Water Facility is currently zoned agriculture, A. The proposed USR is consistent with Section 23-3-10 Agriculture and Section 23-3-40 Agriculture Intent and Uses by Special Review respectively, of Chapter 23 of the Weld County Code. This facility preserves the existing rangeland of the property per the intent of chapter 23 while applying an acceptable use by special review (commercial/industrial) as noted in section 23-3-40 (A and S). The intent of the project, as noted in question number 2 above is that the site will provide support service for the oil and gas industry. 4. What type of uses surround the site(explain how the proposed use is consistent and compatible with surrounding land uses). The Weitzel Sec 33 Water Facility is adjacent to the following properties: • To the east is an approximately 198 acre parcel zoned agriculture (A) containing a residence along the north property line. • To the west is the remaining portion of the property outside of the USR boundary, also zoned agriculture (A). The land is part of the Weitzel Ranch. • To the north is the remaining portion of the property outside of the USR boundary, also zoned agriculture (A). The land is part of the Weitzel Ranch. • South of County Road 74 is Morgan County. Land uses appear to be either open pasture or farmland. The proposed use is compatible with the surrounding uses as the property is surrounded on the north, west, and east by the same zoning (A). All surrounding properties appear to be open pasture, grazing land, or farmland. 5. Describe, in detail,the following: a) Number of people who will use site: This site will not have full time employees on-site.The site will be accessed by truck drivers picking up water, by employees checking on the remote facility to ensure that the facility is within good working condition or temporarily by a pipe laying crew installing piping and plumbing for a specific project. Generally the site will have days with zero (0) people on site to an approximate maximum of forty(40) people on site in a 24-hour period during peak trucking operations. On average over the course of a year, between trucks and operations,there may be sixteen (16) visits to the site per day. b) Number of on-site employees: This site will not have full time employees on-site. On average, the site will be accessed by 15 water haulers per day to pick up water and one employee per day for maintenance of the property. Lamp, Rynearson&Associates, Inc. Page 2 Project No.0212010.00 MSS c) Hours of operation: The site will not have full time operations.The reservoir will be managed, filled, and emptied, by telemetry. However,the specific times that water haulers will access the facility will vary. Potentially, water haulers can access the site twenty four hours a day, seven days a week, every day of the year. d) Type and number of structures to be built: No proposed structures (large buildings) are being built.The existing facility includes an 80,000 barrel storage pond, a skid mounted pump house building, and a three bay load out facility for water trucks. e) Type and number of animals: The property is a ranch so the existing cattle will remain on site. A barbed wire fence protects the reservoir and the well from cattle. f) Kind of vehicles(type, size,weight)that will access this site and how often: 1. The site is accessed by an existing oil well lease road.The existing traffic to the oil well site will continue to use this road. 2. Additionally, it is anticipated that vehicles will consist of: a. On average, one trip per day for miscellaneous maintenance to the facility using a Select Energy Services pickup truck. b. On average, 5 trips per 8 hour day by 130 barrel capacity tanker trucks, comparable to WB-50 trucks. During peak operations an estimated maximum of 13 trips per 8-hour day may be required for a period of 15 days and distributed such that during 8 hours the peak hour may have 2 or 3 trips Please refer to the Traffic Narrative provided with this submittal. g) Who will provide fire protection to the site: Fire protection for the site will be provided by the Briggsdale Fire Protection District. h) Water source on the property: The site will not have potable water since there are no facilities located on-site. i) Sewage disposal system on the property: The site will not have sewer service since there are no facilities located on-site. Portable toilet facilities will be provided for truck drivers. j) If storage or warehousing is proposed,what type of items will be stored: No storage or warehousing will be located on site. 6. Explain the proposed landscaping for the site.The landscaping shall be separately submitted as a landscape plan map as part of the application submittal. Lamp, Rynearson&Associates, Inc. Page 3 Project No.0212010.00 MSS Since the site is located within agricultural property that is sparsly vegetated, all disturbed areas are reseeded with native grass mixes. 7. Explain any proposed reclamation procedures when termination of the Use by Special Review activity occurs. It is not envisioned that the operations will be terminated but if they are pipe will be removed from the ground, pond liner will be removed, embankments will be graded to fill in the existing pond,fences will be removed, and seeding will be used to stabilize the area disturbed. The access to the site will remain since was an existing access for agriculture and a lease access for existing oil/gas facilities on site. 8. Explain how the storm water drainage will be handled on the site: Stormwater drainage will continue to follow historic patterns. In general, stormwater travels from the northeast to the southwest across the site. Stormwater does not overland flow into the water storage pond,therefore the only stormwater that will enter the pond would be directly from a precipitation event. Runoff from gravel access and turnaround areas will sheet flow to basic best management practices for water quality and detention if necessary. Please refer to the Drainage Analysis provided with this submittal. 9. Explain how long it will take to construct this site and when construction and landscaping is scheduled to begin. The site has been constructed and is operable today. This USR is to allow the change in use from a storage pond originally used for water distribution by pipe.The change in use is to allow truck hauling operations when needed. 10. Explain where storage and/or stockpile of wastes will occur on this site: No storage or stockpiles of wastes are anticipated on 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. Improvements to this site are minimal. Originally the site was developed with a grading permit to allow the use by right. The grading permit improved an existing oil and gas lease road to provide access to the new water well and water storage pond. As part of the access to the pond, a turnaround was provided for trucks which was improved to allow for a water load out facility. Those improvements are currently in place. With this USR, there are not expected to be any additional improvements with the expectation of adding a small water quality improvement pond to capture runoff from the water load out area which is constructed of a gravel drive surface. To address basics, existing fencing is barbed wire to keep cattle away from the existing pond, away from the wells, and off of existing access roads and county roads. Disturbed areas were reseeded with native seed mixes. Drainage improvements were kept to a minimum to promote sheet flow and percolation rather than developing concentrated flows that could produce more significant erosion. As noted, no additional improvements are foreseen with the exception of the small water quality improvement pond. That pond will be constructed with approval of the drainage memo included with this application. Lamp, Rynearson&Associates, Inc.

The property is located in the west half of Section 33, Township 7N, Range 60 West. More specifically the property is located approximately 8,000 feet west of the intersection of Weld County Road (WCR) 74 and WCR 105. The proposed facility is a well water storage and a water load-out facility. The property contains an 80,000 barrel capacity reservoir with three (3) truck filling bays. The reservoir is filled by an existing on- site water well. The non-potable water is used to support oil and gas operations including drilling and hydraulic fracturing. The facility is operated by Select Energy Services. The site will utilize the existing oil and gas lease access road from Weld County Road 74. Anticipated truck traffic to the site includes WB-50 130 barrel water tankers and Select Energy Services personnel pickups. The water facility will be used to provide water for oil and gas drilling operations and hydraulic fracturing jobs. It is the intent of this facility to provide water for oil and gas operations within the Weitzel Ranch and therefore will use piping to deliver water to various drill sites up to 14 miles from the facility. Through the use of piping this facility will significantly reduce the number of truck traffic on the surrounding Weld County roads. For projects not located within the ranch boundary water will be trucked offsite. It is expected that trucks exiting the facility will travel along two different routes. For trucks headed north, the anticipated haul route is to exit the facility and travel east along WCR 74 and then north onto WCR 105. For trucks traveling south, the anticipated haul route is to exit the facility and travel west along WCR 74 and then south onto Morgan County Road 2. The haul route utilized by the trucks will be determined by the location of the job. No staging of trucks will occur on WCR 74. Per the Weld County 2035 Transportation Plan, WCR 74 from WCR 101 to WCR 103 is classified as a local road with a capacity of two hundred (200) vehicles per day. Weld County Road 105 from WCR 74 to 76 is classified as a collector, also with a capacity of two hundred (200) vehicles per day. The site will not have full time employees on-site; however it can be assumed that the site will be accessed daily by a Select Energy Services employee to ensure proper maintenance of the facility. Personnel accessing the site will be driving typical pickup trucks. For normal operations, the average number of trips to the facility by water tankers is anticipated to be three (3)trips per 8-hour day. When a hydraulic fracture requires water an estimated maximum of thirteen (13)trips per 8-hour day may be required for a period of 15 days and distributed such that during 8 hours the peak hour may have 2 or 3 trips. The water tankers have a 130 barrel capacity and can be considered WB-50 type trucks. Loavir,q a Lognry cif Enduring imiimvornonls In Our C,nn nn nrifir>s . ENGINEERS SURVEYORS PLANNERS Traffic Narrative Weitzel Sec 33 Water Facility July 25, 2014 Page 2 of 2 On average, the Weitzel Sec 33 Water Facility will result in an increase of sixteen trips per day to the surrounding county roads. However, the facility is ultimately greatly reducing truck traffic to the surrounding roads by providing a facility that delivers water to various oil and gas locations via a pipe network. In conclusion, the proposed facility will not create a significant increase to the average daily traffic that is already being experienced on WCR 74 and therefore no public improvements to the road or the existing access are proposed. Please contact us if you require any further information or have any questions. Sincerely, LAMP RYNEARSON & ASSOCIATES, INC. John Tufte, PE Project Manager MSS DUST ABATEMENT PLAN SELECT ENERGY SERVICES WEITZEL SEC 33 WATER FACILITY WELD COUNTY, COLORADO Through the life of this project, Select Energy Services will utilize watering and other best management dust suppression practices to control fugitive dust. On unpaved roads, Select Energy Services will utilize water trucks as needed to control dust. Vehicle speeds will also be limited to ten miles per hour to reduce dust. The main access drive, truck circulation areas, and truck loading areas are constructed with road base, thereby reducing dust emission. If areas are disturbed due to facility maintenance activities, disturbances will be watered to control dust as needed and vehicle speeds will be limited to ten miles per hour. Revegetation of the disturbed area shall be completed within one year. To prevent dust emissions, disturbed soil shall be furrowed a minimum of six inches deep at right angles to prevailing winds. If needed, silt fence shall be installed as a wind break. Water used for dust suppression will be provided by the onsite source and Select water trucks. Lamp, Rynearson&Associates, Inc.

More specifically the property is located approximately 8,000 feet west of the intersection of Weld County Road (WCR) 74 and WCR 105. This is approximately 14 miles southwest of New Raymer. The existing site is comprised of agricultural-grazing land with soils consisting of Olney fine sandy loam and Ascalon fine sandy loam. The area considered for this drainage analysis accounts for approximately 10.8 acres of the approximate 318 acres of the platted parcel. Existing structures within the parcel include oil and gas wells and associated production equipment including an access road. Site Conditions Site conditions include a ± 1.7 acre, freshwater storage pond and gravel access road with turn-around and a three truck loading area for fresh water hauling. An emergency spillway is proposed for the west side of the pond and will direct flow to an existing drainage way through the property. The site will be accessed from WCR 74 via the existing oil and gas access road running north to south. In general, stormwater flows overland from the northeast to the southwest across the site. An existing drainage way exists along the top edge of the ridge located in the approximate center of the 40 acre USR boundary. Analysis & Results A drainage area of 10.85 acres was defined for the the purposes of the following calculations. This area encompasses the facility located within a barbed wire fence. The existing conditions of the property were analyzed as the historic condition. Prior to construction, the property was used primarily for grazing with an oil and gas access road. The percent impervious was calculated to be 1.0%. With the addition of the reconstructed access road, gravel turn around, loading area, and pump house, the percent impervious was calculated to be 7.0%. The increase in imperviousness resulted in a minor increase in peak runoff. For the 10-year and 100-year design storms, the peak runoff increased by 2.4 Ltvnvinq II Lrgnry of Enduring Imprnvmnontc to Our C111111111111/110S - u r Ats-&1='.n.: ENGINEERS SURVEYORS PLANNERS and 3.6 cfs respectively. The fresh water storage pond is not intended to capture surface stormwater flows and only receives storm event precipitation. The pond is designed to include an emergency spillway. Given the pond water surface area and an assumed 100% imperviousness for the water surface, a 100-year peak flow rate of 12.5 cfs was calculated. The emergency spillway was designed to convey the peak flow rate resulting in spillway dimensions of 40-foot in length by 0.5-foot in depth. In addition, the pond design allows for one-foot of freeboard above the maximum freshwater storage surface elevation. Therefore, the emergency spillway and overflow channel would be implemented only after the one- foot freeboard depth has been used. See attached supporting calculations. Conclusion The proposed site conditions result in a minor increase in peak runoff rates. Stormwater drainage will continue to follow historic patterns. The freshwater storage pond is not intended to receive surface runoff and will only capture storm precipitation. The emergency spillway was conservatively sized to pass the 100-year design storm event. If you have any questions or concerns, please feel free to contact me at your convenience.

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 (ND, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential)when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture.These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential)when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.
