Explain, in detail, the proposed use of the property This USR application is referred to as the Anadarko Exploration and Production (E&P) Waste Management Facility and it is provided from Kerr-McGee Oil & Gas Onshore LP. The facility is located on property owned by Anadarko E&P Onshore LLC, northwest of the intersection of Weld County Road 22 and Weld County Road 31, near Fort Lupton. If the proposed USR is approved, the site will be used to recycle and recondition used mud/fluids from completions, midstream and production for re -use in future oil and gas operations including: warkaver/intervention operations, completions, and new drilling operations. In addition, if needed, the facility can be used for the production of fresh mud for workover drilling and new drilling activities. All recycled mud/fluids produced at the Facility will be transported back to the location where they were originally produced via truck. Recycled mud/fluids will be used for the following application: • Spacing fluid between cemented intervals below surface casing • Kill fluid/workaver fluids below surface casing • Drilling fluids below surface casing • Completions fluids Recycled mud/fluids will NOT be used for the following applications: • Drilling fluid for the surface casing interval • Fluid for cement • Workover fluids that have the potential for contact with fresh water aquifers. The proposed use is located on parcel 130909000019 in Weld County and measures approximately 2.4 acres in total area (includes proposed detention). The overall parcel is approximately 103 acres in total area. The parcel is located approximately 4.8 miles to the north and east of Fort Lupton. The parcel is bordered by Weld County Road 31 the east and Weld County Road 22 to the south. It is currently zoned Agricultural and is surrounded by Agricultural zoned properties. There are agricultural uses/improvements located to the east and other oil field operations located to the north. There are some single-family uses located to the south of the facility approximately one- half mile away. There is also an existing oil well facility located directly to the west of the waste management facility on the subject property (Aggregate State 37C-16HZ). It should be noted that this facility is currently in operation and was previously approved through the COGCC as a temporary use. This facility was also approved by Weld County in November of E&P Waste Managment Facility Proposed Use by Special Review Kerr McGee Oil & Gas Onshore LP 5 2015 as part of a temporary pilot program. Kerr McGee is working with the COGCC to make the facility permanent through the approval of a Form 28 application per Rule 908. The intent of this USR application will be to make the facility permanent with Weld County as well. A description of the proposed traffic associated with the site is provided in the attached memorandum. The access road for the waste management facility is existing and is located along WCR 31— approximately 0.32 miles north of WCR 22. The access point is permitted under AP 14- 0006 1.

Reference to Weld County Master Drainage Plan(s) where applicable: There are no known Weld County Master Drainage Plans for the project site. 2. Major basin drainage characteristics: There are no known details of the drainage basin characteristics of the project site defined by a Master Drainage Plan on record. 3. Identification of all FEMA-defined 100 -year floodplains and floodways affecting the property: The property lies within the FEMA FIRM Panel 08123C1920E which contains no floodplains. The Platte River floodplain is approximately 3 miles due east of the site. The FEMA Panel is located in Appendix B. 4. On -site & offsite contours at minimum 2 -ft vertical intervals are to be included on the Drainage Report Drawings: Topography at the project site has been provided from a recent engineering survey and LiDAR contours. Contours are labeled accordingly on the Drainage Plan provided in Appendix G. B. SUB -BASIN DESCRIPTION 1. Historic Drainage patterns on the subject property and adjacent properties: The topography within the disturbance limits drains from the east to the west at a 2% average slope. Surrounding topography within the property generally slopes down from southeast to northwest at 2%, bypassing the proposed site to the north and south. The north adjacent property flows east to west and does not enter the site property. Flows from the east property are separated from the site by Weld County Road 31. Basin P1, which encompasses the entire facility, is 1.99 acres located in the north portion of the property. Water will flow from the eastern edge of the basin across the site and into a detention pond, where an outlet structure will release runoff to the west. Basin P1 overall post construction imperviousness is 4185% with a 100 -year discharge of 0.46 cfs, based on the historic 10-yr release. 2 2. Off -site drainage flow patterns and impacts on the subject property (minimum 200 ft outside property boundary or until no further off -site contributing flow area is encountered): There are no significant off -site drainage flows entering the property. The property to the north drains in an easterly direction does not flow into the property. Runoff from the eastern property is separated from the subject property by WCR 31. To the south of the project area, existing topography directs flows to the west-northwest into a ditch along the north property line and eventually into the Platteville Ditch. III DRAINAGE DESIGN CRITERIA A. DEVELOPMENT CRITERIA REFERENCE AND CONSTRAINTS 1. Discussion of previous drainage studies (i.e. project master plans) for the subject property that influence or are influenced by the proposed drainage design for the site: There are no known drainage studies that affect this property. 2. Discussion of site constraints such as slopes, streets, utilities, existing structures, irrigation ditches, and the site plan impacts on the proposed drainage plan: Existing topography onsite includes a channel which will be expanded to create the required stormwater detention for this project. Existing structures will not be affected by the addition of a detention pond. Stormwater discharges will be directed to the west where they have historically flowed. B HYDROLOGICAL CRITERIA 1. Identify design rainfall amounts and source of design storm depth information, NOAA Atlas, UD&FCD maps, etc.: Design rainfall depths were taken from the UDFCD Urban Storm Drainage Criteria Manual, Volume 1. The Drainage calculations can be viewed in Appendices C, D, and E of this report. The UDFCD rainfall depth -duration -frequency charts can be found in Appendix H. 2. Identify design storm recurrence intervals. Reference the appropriate information in the Appendix: Design storm recurrence intervals of 5 -year and 100 -year were examined in this study. The historic 1 -hour 10 -year event release rate was used since the site is within a NON URBANIZING area. Relevant calculations can be viewed in Appendices C, D, and E of this report. 3. Identify runoff calculation method(s) and any computer models. Include summaries of the routing and accumulation of flows at all identified design points for minor and major storm runoff. Reference the results in the Appendix: The Rational Method was used to determine developed flow volumes. The Rational Formula is Q = CiA, where C., the maximum rate of runoff is equal to the runoff coefficient C, times the rainfall intensity (I), times the area (A). Sheet 3 flows within the basin are directed either directly into the detention pond, or into a drainage swale along the north edge of the site that drains into the detention pond. Relevant calculations can be viewed in Appendices C, D, and E of this report. 4. Identify detention discharge and storage calculation methods and computer models. Reference the results in the Appendix: Stormwater Detention storage and discharges were calculated using the UDFCD UD-Detention spreadsheet. Per Weld County's criteria, the detention pond was designed for the 1 -hour, 100 -year storm. The volume of this event was calculated to be 0.17 acre-feet at an elevation of 4925.85. The proposed detention pond berm is set at 4927.00 with a 20' wide emergency spillway at 4926.25 that is capable of releasing the peak 100 -year runoff at a depth of 216 inches. Calculations are shown in Appendix F. 5. Discuss how off -site flows will be routed around the proposed site or over the spillway for the 100-yr developed condition: The proposed basin is kept small by both existing topography and previous improvements. Flows coming from the south are directed around the site to the west by way of the existing access road. Flows from the east are directed around the site to the north and west via the access road and existing topography. The detention pond is positioned on the western portion of the site so that flows from the outlet structure and emergency spillway can follow historic flow paths. C HYDRAULIC CRITERIA 1. The hydraulic criteria and drainage design features of this project were designed in accordance with the Denver, Colorado, Urban Drainage and Flood Control District's (UDFC) "Urban Storm Drainage Criteria Manual," Volumes 1-3 and Weld County Storm Drainage Criteria identified in Chapter 23, Article 12 of the Weld County Code. 2. Identify detention outlet type. Include a summary of the 100 -year water surface elevation, spillway/overflow facility. Reference the appendix for the calculations. Include summaries of the detention storage sizing and provide a stage -storage table/curve identifying water quality storage, 100 -year detention pond storage, and 1 ft of freeboard. Reference the calculations in the Appendix: An outlet structure with an internal micropool, water quality orifice plate, outlet pipe with a restrictor plate, and an overflow spillway has been provided to release stormwater runoff at a controlled rate. The total maximum volume stored in the pond is 0.17 ac -ft at the 100-yr water surface elevation of 4925.85. The top of pond is set at 4927.00 which provide 0.75' of freeboard above the emergency spillway. A 15" outlet pipe with a restrictor plate will 4 control 100-yr outflows, and an 20' wide spillway at elevation 492625 ft accounts for overflow capacity at a depth of 2.16 inches for the peak 100-yr outflow. Appendix F contains all pertinent calculations, and Appendix G includes the outlet structure details. 3. Identify the water quality outlet configuration. Reference the calculations in the Appendix: The water quality outlet is provided as an orifice plate with one row of three 1/2" diameter holes designed to drain the WQCV within 40 hours. Calculations are provided in Appendix F. 4. Identify culverts including diameter, type, and slope. Reference the calculations in the Appendix: There are no proposed culverts for this project. 5. Identify storm sewer inlets, manholes, etc. Reference the calculations in the Appendix: There are no related improvements of this nature proposed in this project. 6. Discussion of permanent erosion control features: Buried riprap from the spillway to the embankment toe at the emergency spillway► will be included per Weld County requirements, as well as a riprap section at the outlet pipe to protect downstream property from pond outflows. After pond construction is completed, it shall be reseeded per the revegetation requirements outlined in Section 23-12-100 of the Weld County Code. 7. Discussion and justification of criteria or calculation methods (for water quality, check dams, drop structures, rundowns, etc.) used that are not presented in Weld County Code: All calculations and structures utilized in this detention pond design follow the UDFCD and Weld County Criteria. IV DRAINAGE FACILITY DESIGN A. GENERAL CONCEPT 1. Discussion of concept and typical on -site drainage patterns: The site consists of a gravel pad and access road, fluid recycling equipment, and existing ground cover as described in the NRCS Soil Survey. All drainage that occurs within the disturbance limits will be directed into the detention pond by overland flow across the facility pad or by a drainage swale along the northern edge of the disturbance limits. Once in the pond, an outlet structure will control release rates for both the water quality capture volume and 100 -year storm event, while an emergency spillway accounts for events greater than the 1 -hour, 100 -year storm. 5 2. Discussion of compliance with offesite runoff considerations and constraints: The Weld County requirements for sites within a NON URBANIZING area include releasing the 1 -hour, 100 -year storm runoff at the historic 1 -hour, 10 -year flow. On this site, the calculated historic 10 -year flow was 0.46 CFS. 3. Discussion of the content of all tables, charts, figures or drawings in the report: Each of the Appendices provided in this report are discussed throughout the narrative of this document as they pertain to each topic. The list of Appendices to this report include the following: Appendix A: NRCS Soils Map — Includes map and report discussing the soil conditions in accordance with soil classifications which include properties and features and hydrologic soil group for drainage calculations. Appendix B: FEMA Map — Attached FEMA FIRMette within panel 0812301920E with an effective date of January 20, 2016. The project location is identified on the map for reference. Appendix C: Composite "C" Factors — Standard Form 1 from the UDFCD and Weld County Code which identify the various coefficients present on -site which are combined to create a composite "C" value used in the formula to calculate site runoff. Appendix D: Time of Concentration — Standard Form 2 from the UDFCD and Weld County Code utilize variables including but not limited to the drainage basin area, slope, length, etc. as defined by the rational method of computation for peak flow values. Appendix E: Storm Drainage System Design — Standard Form 3 from UDFCD and Weld County Code including rational method computations for 5 -year and 100 -year peak runoff values in cfs. Appendix F: Detention Pond Design Calculations — includes Hydrograph p h Report and data utilized to determine required detention pond volume, as well as outlet structure design information. Appendix G: Proposed Drainage Plan — Includes Sheet C5 (Drainage Plan) and Sheet C6 (Outlet Details) which show the necessary information as requested by the Weld County Site Plan Review and the Drainage Report Outline checklist. Appendix H: Rainfall Depth -Duration -Frequency Estimates for the 5 -year and 100 -year storm events from USDCM Volume 1, Chapter 5. 4. Discussion of anticipated hydraulic structures (channels, pipes, rundowns, etc.): An existing drainage swale along the north edge of the disturbance limits will drain into the eastern portion of the detention pond. The outlet structure includes a 15" reinforced concrete pipe with a restrictor plate. The emergency spillway will include a concrete cutoff wall per Weld County detention storage requirements. B. SPECIFIC DETAILS 1. Discussion of maintenance access and aspects of the design. Include a maintenance plan: The detention pond has maximum side slopes of 4:1 to allow access to the outlet structure. The site shall be maintained by the owner in accordance with Weld County Code. Debris and other accumulations that might reduce the storage capacity of the pond shall be monitored and removed as necessary. In order to ensure that the stormwater facility functions as designed, the owner will need to maintain the pond. Future maintenance of the pond show include the following: -Educate property owners/residents to be aware of how their actions impact water quality, and how they can help reduce maintenance costs - Keep properties, gravel roads and parking areas free of trash and debris. - Ensure the proper disposal of hazardous wastes and chemicals - Sweep paved surfaces and put the sweepings in a compost pile. - Be aware of automobiles leaking fluids. Use absorbents such as cat litter to soak up drippings — dispose of properly - Re -vegetate disturbed are bare areas to maintain vegetative stabilization. - Clean out the upstream components of the storm drainage system, including inlets, storm sewers and outfalls - Do not store materials outdoors (including landscaping materials) unless they are properly protected from stormwater runoff 2. Provide copies of CDPHE, CAFO, DRMS, or State Engineer's permit applications where applicable: No additional permit applications are included with this project. V. CONCLUSIONS A COMPLIANCE WITH STANDARDS 1. Statement of whether or not the design will meet Weld County Code: To the best of my knowledge, the drainage design set forth in the plans and specifications complies with the Weld County Standards. B DRAINAGE CONCEPT 1. Effectiveness of drainage design to control damage from storm runoff: The proposed detention pond will serve to control developed stormwater runoff and discharge the flows at a safe rate for downstream properties. 2. Influence of proposed development on any applicable Weld County Master Drainage Plan recommendations: The project site is located in an area that is not defined by a Master Drainage Plan on record. There is no proposed development associated with this project that would greatly influence the drainage conditions of the site. Current drainage patterns will be retained and there will be no damage due to stormwater runoff from this site. 3. Identification of and intent to obtain written approval of affected irrigation company or other property owner(s). Weld County may require that the applicant provide evidence that offsite impacted jurisdictions have been notified or the proposed plans: There are no impacts of this project to irrigation companies or other property owners. The site is currently used as fluid recycling facility for Anadarko Petroleum, and the property owner maintains the site. The site is in the middle of a large parcel owned by Anadarko E&P Onshore LLC, and flows from the site will not affect adjacent property owners. 4.

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 CID). 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.

Include overall post construction site imperviousness The overall post construction site imperviousness has been included in section B.1 of the drainage report. CONSTRUCTION DRAWINGS: 2. Drawings of outlet structure to be included in the drainage report. Details have been included in the drainage report. COMMENTS: 3. Please use "100 % imperviousness value for the water surface area of the pond in the rational calculations. It looks like a "pond" column was added to the impervious calculations, but a 0% impervious value was used. The imperviousness of the pond was revised to be 100% for the rational calculations. 4. The pond volume should be taken from the "maximum volume stored (acre -ft)" column in the UDFCD spreadsheet. The volume should be 0.217 acre -ft, which equates to a water surface in the pond of approximately 4926.19. The volumes will change slightly with the increase in impervious percentage of the pond water surface. Please update calculations and details are required. Maximum pond volume stored updated based on the revised calculations from the UDFCD spreadsheet, see revised plans and report. Attached please find the drainage report as requested. We look forward to the final approval based on these minor changes.

Appendices Appendix A - Site plan Appendix B - Construction drawings Appendix C - Inspection Form(s) Appendix D - Maintenance Form(s) Appendix E - Stormwater Facility Maintenance Notification Form I. Reasons for Stormwater Facility Maintenance A. The purpose of this plan is to ensure property owners follow proper operation and maintenance procedures for stormwater management facilities located on their sites. Requirements for inspection and maintenance, as well as reporting requirements are located in this Stormwater Management Facility Guidance Document. Additional information can be found in the Urban Drainage Manual or by contacting the Weld County Engineering Division. B. Preventive Measures to Reduce Maintenance Costs The most effective way to maintain your water quality facility is to prevent the pollutants from entering the facility in the first place. Common pollutants include sediment, trash and debris, chemicals, pet wastes, runoff from stored materials, illicit discharges into the storm drainage system and many others. A thorough maintenance program will include measures to address these potential contaminants, and will save money and time in the long run. Key points to consider in your maintenance program include: • Educate property owners/residents to be aware of how their actions impact water quality, and how they can help reduce maintenance costs. • Keep properties, streets and curb & gutters, and parking lots free of trash, debris, and lawn clippings. • Ensure the proper disposal of hazardous wastes and chemicals. • Plan lawn care to minimize the use of chemicals and pesticides. • Sweep paved surfaces and put the sweepings in a compost pile or back on the lawn. • Be aware of automobiles leaking fluids. Use absorbents such as cat litter to soak up drippings — dispose of properly. • Re -vegetate disturbed and bare areas to maintain vegetative stabilization. • Clean out the upstream components of the storm drainage system, including inlets, storm sewers and outfalls. • Do not store materials outdoors (including landscaping materials) unless they are properly protected from stormwater runoff. H. GENERAL LOCATION AND► DESCRIPTIO General Site Description The subject property is located in the southeast 1/4 of Section 9, Township 2 North, Range 66 West of the 6th P.M., Weld County, Colorado. The parcel is bordered by Weld County Road (WCR) 31 to the east and Weld County Road 22 to the south. The Fulton Extension Ditch traverses along the eastern portion of the parcel, and the Twombly Reservoir comprises the southern portion of the property. There are no known developments surrounding the site. WCR 31 abuts the site to the east, and WCR 22 to the south, both governed by Weld County. The City of Fort Lupton lies approximately 7 miles to the south. There are no known channels, irrigation ditches, or streams adjacent to the site. There are no known developments surrounding the site. In order manage stormwater runoff to prevent flooding and downstream erosion, and improve water quality; a stormwater detention pond is incorporated into the development and proportionately sized according to the contributing basin area and runoff volume. III. STORMWAT,E,R MANAGEMENT FACILITIES 1 Inspection Inspect the pond at least annually. Note the amount of sediment and look for debris. 2 Debris and Litter Removal Remove debris and litter from the pond as needed. 3 Aquatic Plant Harvesting Harvesting plants will permanently remove nutrients from the system, although removal of vegetation can also re -suspend sediment and leave areas susceptible to erosion. Additionally, the plants growing on the safety wetland bench of a retention pond help prevent drowning accidents by demarking the pond boundary and creating a visual barrier. For this reason, UDFCD does not recommend harvesting vegetation completely as routine maintenance. However, aquatic plant harvesting can be performed if desired to maintain volume or eliminate nuisances related to overgrowth of vegetation. When this is the case, perform this activity during the dry season (November to February). This can be performed manually or with specialized machinery. if a reduction in cattails is desired, harvest them annually, especially in areas of new growth. Cut them at the base of the plant just below the waterline, or slowly pull the shoot out from the base. Cattail removal should be done during late summer to deprive the roots of food and reduce their ability to survive winter. Weekly mosquito inspections with targeted treatments are frequently less costly and more effective than regular widespread application of insecticide. 4 Mosquito Control Mosquito control may be necessary if the BMP is located in proximity to outdoor amenities. The most effective mosquito control programs include weekly inspection for signs of mosquito breeding with treatment provided when breeding is found. These inspections and treatment can be performed by a mosquito control service and typically start in mid -May and extend to mid -September. The use of larvicidal briquettes or "dunks" is not recommended for ponds due to their size and configuration. 5 Sediment Removal Remove sediment before it becomes a significant source of pollutants for the remainder of the pond. More frequent removal will benefit long-term maintenance practices. Sediment removal in should occur approximately once a year or when build up of sediment results in excessive algae growth or mosquito production. Ensure that the sediment is disposed of properly and not placed elsewhere in the pond. 6 Sediment Removal from the Pond Bottom Regrading of the pond bottom may be required every 10 to 20 years to maintain volume and deter algae growth. This typically requires heavy equipment, designated corridors, and considerable expense. Harvesting of vegetation may also be desirable for nutrient removal. When removing vegetation from the pond, take care not to create or leave areas of disturbed soil susceptible to erosion.

We have two Low Pressure discharge pipelines going from our Powars compressor station to the existing lines heading east that are going in right now. They only run from the Powars compressor station across the southern end of the Basalite property. Since these gas pipelines are low pressure, we don't need any permits form the county, correct?

Lupton but we keep missing each other. Platteville doesn't have any interest in annexing this property and does not object to the USR. The property is located in a joint planning area with Ft. Lupton but we wouldn't annex due to having to pick up a road on the flagpole and it's not cost effective.. Thanks for reminding me about the USR and just let me know if I can assist further.
