Explain, in detail, the proposed use of the property. Noble Energy has a Memorandum Agreement and Letter of Authorization in place with the Castor Family (enclosed with this application) and will be purchasing an 80 acre parcel from Wade E. Castor and Deland Todd Castor to own and operate an Oil and Gas Centralized Processing Facility. They will sublease approximately twenty acres to Wattenberg Holding, LLC for their portion of the facility. Both Noble Energy and Wattenberg Holding, LLC are applicants for this USR and both applicants have signed and submitted the application. Signature blocks for both Noble Energy and Wattenberg Holding are included on the USR Plat Map. The property is located south of and adjacent to Weld County Road 104 and west of and adjacent to WCR 115 right-of-way, in the A (Agricultural) Zone District in Weld County, Colorado. The parcel is located in the east half of the northeast quarter of Section 21, Township 9 North, Range 59 West of the 6th P.M, Weld County, Colorado. The facility will be used by Noble Energy for oil and gas processing equipment, fresh water ponds, an office and Use by Right Communications Tower (35' or less) and by Wattenberg Holding, LLC for crude oil storage, office, shop/warehouse and a four bay truck unloading facility. Question 51. and the Traffic Narrative included with this application, address the associated traffic associated with this facility. Overall, the facility will be open 24 hours per day, seven days per week, 365 days per year and is planned to be a secure facility with chain link fencing around the site as shown on the USR plat map. Following is how Noble Energy and Wattenberg Holding, LLC will operate their respective portions of the facility: Noble Energy: Noble Energy's wells, surrounding this site, will be conveying product (a combination of oil/gas/water) to the East Pony facility, primarily via pipeline. Initially, 100% of the oiUgas/water will be conveyed via pipelines. When the Truck Unloading Facility is built 10- 15% of the oil could be trucked to this facility and would primarily come from outlying wells. If the outlying wells are 10 miles away or more, from the East Pony facility, is not economically feasible to pipe the product from that distance. Before the product leaves the well site, produced water will be initially separated from the oil and gas at the tank battery so that the product contains no more than 2% water. Once the product reaches the East Pony Facility, it will be further separated to decrease the water content to 0.3% or less. The produced water separated off at the East Pony Facility will be stored in tanks and later trucked or piped to a third party approved disposal facility within the area. The water storage tanks will be 40,000 barrel tanks, as shown on the USR Plat map and will approximately 48' tall. The gas separated out will be piped to Noble's Keota Gas Plant or the Lilli Gas Plant (the gas pipeline is planned to be a 16", 50psi with under a 20% hoop strength pipeline). The oil separated out will either be sent to Wattenberg Holding, LLC's oil storage facility on this site to be transported via the Wattenberg Extension Pipeline or it will be directed to Noble's oil storage tanks to be transported through the inlet and LACT meters and enter the Tall Grass Pipeline, located on the western edge of the property. Tallgrass and Noble Energy are currently working on finalizing the License Agreement for the meter area and right-of-way to the meter area. Once this agreement is completed, a copy will be provided to Weld County Planning. Tallgrass currently has easements for their pipeline on the property west of and adjacent to the East Pony site. There will be fresh water ponds and a load out facility on site with water being piped from a deep aquifer well in the area, most likely from the Timmerman Ranch. The pipeline will be within a private easement to the site and the easements are in place. These pipelines are Noble Energy pipelines for fresh water transport. The water may be piped to wells in the 1 area, but Noble would like to have the option of trucking the fresh water, as described below. There will be secondary containment areas for the tanks, as shown on the USR plat map. Noble's tanks are located in the southwestern corner of the facility. As requested, containment areas will be designed for sufficient capacity to contain the volume of the largest single tank including sufficient freeboard for precipitation. The engineered design of the containment areas will certify that the any alternative liner material meets the expected function of concrete with regards to spill containment. The containment plans will be submitted to the Weld County Department of Public Health and Environment, prior to the release of building permits for Noble's facility. Noble would like to include an option for this USR for a Temporary Water Depot to be used when hydraulically fracturing wells in the vicinity of this site. The Temporary Water Depot would include about 30-40 trucks per day, for an approximately four day period during the time that the well is being fractured. The trucks carrying water are already on Weld County roads, but would currently be hauling water from longer distances away from the wells in this area. The Water Depot would significantly cut down on the hauling distance. We discussed working with Public Works to have a Road Improvement and Maintenance Agreement for this use with triggers for dust control and other road maintenance. A 35' or less communication tower is planned for this facility and will be on Noble's own frequency, to ensure communication service for Noble's employees. Noble is planning on having up to five employees on site, each day. Wattenberg Holding, LLC: Wattenberg Holding, LLC will have storage tanks on the property that will accept the oil from Noble Energy's processing facility on the northern and western portions of this site. There is secondary containment shown on the USR plat map for Wattenberg's tanks, which are located in the southeast corner of the facility. Containment areas will be designed to meet regulatory requirements and industry standards. Oil from the tanks will be metered as it enters and leaves the tanks. Oil leaving the tanks will be directed into the 12" Wattenberg Extension Pipeline that runs along the eastern portion of this site, on its way to the Platteville Truck Unloading Facility (aka Rose Rock Truck Unloading Facility — AmUSR-1614) at County Road 30 and County Road 49 and then onto Cushing, Oklahoma for further distribution into the market. Wattenberg Holding, LLC is planning on having one employee on site each day, generally from 6:00 a.m. to 4:00 p.m. Wattenberg Holding LLC is proposing a future truck unloading bay and canopy. It is not anticipated that this facility will need to unload oil by truck, but it if the pipelines become over capacity, they would like to leave that option for the future. An updated traffic study will be completed and submitted to Weld County prior construction of the truck unloading portion of the facility. The design will incorporate a concrete unloading pad to accommodate unloading trucks and coupling with the unloading bay. The design will demonstrate how spilled waste will be contained within the receiving areas and sumps. The design will include the method in which seams will be sealed to prevent leakage through the pad. A Colorado registered professional engineer will design the structure. Traffic is discussed in Question 51 further in this questionnaire. There are other permits that Noble Energy and Wattenberg Holding, LLC will submit to the State of Colorado for this project. If requested, copies of these permits may be provided to Weld County. Copies of the Air Pollution Emission Notice permit information are included with this application for Noble Energy and for Wattenberg Holding, LLC. A groundwater monitoring plan is not anticipated for 2 this facility at this time. A Secondary Containment and Unloading Pad Plan will be provided 30 days prior to construction of that portion of the facility, where required. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. The Weld County Comprehensive Plan has Goals and supporting Policies that encourage responsible Oil and Gas development in the County. Below is a list of the specific Oil and Gas goals followed by an explanation of how the goals are being addressed: OG.Goal 1: Promote the reasonable and orderly exploration and development of oil and gas mineral resources. OG.Goal 2: Ensure that the extraction of oil and gas resources conserves the land and minimizes the impact on surrounding land and the existing surrounding land use. OG Goal 3: Prevent surface and groundwater contamination from oil and gas minerals exploration and extraction. The proposed East Pony Centralized Processing facility is an area of Weld County that is very active with oil and gas wells and associated facilities. The nearest residence to the site is approximately one mile north of the facility. There are a few other homes in the area, but all of them are over a mile from this site. The East Pony facility, will minimally impact surrounding properties since the oil and gas entering and leaving the site is via pipeline. There will be some initial impacts during construction, but once the facility is constructed, the impacts should be minimal. Dust will be controlled with water during construction of the facility. Traffic will be minimal at this site and is further discussed in 5.1 below. The site will be designed to have detention ponds that will be used to control surface water in the event of a storm. (See attached Final Drainage Report and Plan). 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. According to the Weld County Code, oil and gas support and service facilities are a Use by Special Review in the Agricultural Zoning District. Crude oil processing facilities would be considered oil and gas support facilities which is the reason a Use by Special Review application is being submitted. 4. What type of uses surround the site (explain how the proposed use is consistent and compatible with surrounding land uses). The project is located in a very remote area of the county where open dryland prairie and other oil and gas facilities are the primary land uses. The Pawnee Buttes are north of this area and there are very few residences in the area, the closest being approximately one mile away. Due to the fact that the facility will generate so little traffic, the use will be consistent with the multitude of other oil and gas facilities in the area and compatible with the few residential land uses that are located in the vicinity. 5. Describe, in detail, the following: a. Number of people who will use this site. Both Noble's and Wattenberg Holding, LLC's facilities on this site will operate 24 hours a day, 7 days a week, 365 days per year. Approximately six employees will be at the site on a daily basis; five Noble employees and one Wattenberg Holding, LLC employee. b. Number of employees proposed to be employed at this site. See above. c. Hours of operation. The site will operate 24 hours a day, 7 days per week, 365 days per year. Noble Energy will have two twelve hour shifts (6:00 a.m. to 6:00 p.m.) with Wattenberg Holding having one shift from 6:00 a.m. to 4:00 p.m. 3 d. Type and Number of structures to be erected (built) on this site. Noble's proposed improvements/structures include: • Heaters (5) • Stabilizing Tower (5), estimated 65' tall • Flash Gas Compressors (6) • Transfer Pump Skid • 60,000 Gallon Discharge Bullet Tanks (3) • 60,000 Gallon Inlet Bullet Tanks (5) • Gas Scrubber (2) • Free Water Knockouts (8) • Heater Treaters (8) • MCC Structures (2) • Booster Compressors (6) • 250,000 BBL Tanks (2) • 40,000 BBL Tanks Produced Water (2) • 40,000 BBL Oil Tanks (4) • 5,000 BBL Tank • 500 BBL Biocide Tank • 500 BBL Chemical Tank • Pump Skids • Pump house • Meter area (100' x 100' pad site) • Flare • Office Building, estimated 15' x 40' • Instrument Air Building • Fire Foam Building • Shop Building, estimated 60' x 30' • Communication Tower (35' or less) Wattenberg Holding, LLC's proposed improvements/structures include: • Office Buildings (2) Estimated dimensions: 15' tall, 15' wide, 40' long • 12' x 12' General Building (2) • General Electrical areas for pipeline and other equipment • Equipment areas • 122' Diameter Tanks (100,000 BBL) (2) • 87' Diameter Tank (50,000 BBL) • 35' Diameter Tanks (5,000 BBL) (4) • Warehouse, estimated dimension: 33' tall, 30' wide, 60' long • Truck Unloading Bays and Canopy for up to four bays estimated dimension: 33' tall, 67' wide, 80' long Dimensions on the equipment listed above for Noble Energy and Wattenberg Holding, LLC will be determined with the final facility design and shown on building permits. e. Type and number of animals, if any, to be on this site. There will be no animals kept on this site. 1. Kind of vehicles (type, size, weight) that will access this site and how often. The East Pony site will generate very little traffic on a day to day basis, since generally all of the oil and gas entering and leaving the site is via pipeline. If a pipeline was shut down temporarily, there could be some minor traffic associated with this facility. Other traffic could include a few incidental vehicles coming to the site for waste pick-up, mail, and deliveries. 4 Total large truck traffic is estimated to be around 17 trucks per day, most of which, will arrive and depart during daylight hours. This number may increase by 5-10 trucks if it becomes necessary to truck water to a third party location. Under worse case conditions, there will be 27 trucks per day arriving and departing the site. Truck arrivals and departures will occur randomly and are estimated at one to two per hour. Employee and miscellaneous site vehicles will typically be passenger cars or pickup trucks and will be in the range of 6-8 vehicles per day. In total, an estimated 35 vehicles per day are expected to visit the site. Noble and Wattenberg Holding, LLC propose to build the main shared access to the site off of Weld County Road 104, basically in the center of the 80 acre parcel, approximately 650' west of the intersection of WCR 104 and WCR 115 right-of-way. Access to the site is shown on the USR Plat map to accommodate both Noble Energy's and Wattenberg Holding, LLC's facilities_ A secondary access is proposed at the intersection of WCR 104 and WCR 115, with limited traffic planned at this access point at this time. (See Traffic Narrative included with this application). Noble Energy is currently having detailed construction plans prepared for WCR 104 and WCR 115 to accommodate the numerous wells and activity within the vicinity of the East Pony CPF. They are already working with Weld County Public Works on the design for this road. The plans will include the design for improvements to the intersection of WCR 104 and WCR 115 and for both of the roads. Weld County Public Works indicated during our Pre -application meeting that there are currently no traffic counts on WCR 104. The Traffic Impact Study was waived and a detailed traffic narrative, prepared by Gene Coppola, P.E., PTOE, is included with this application. See the attached Traffic Narrative for more details. 9. Who will provide fire protection to the site. The property falls within the Pawnee Fire District. We are working on setting up a meeting with the District soon. Water source on the property (both domestic and irrigation). There is no existing water source (domestic or irrigated) on the property. Noble Energy and Wattenberg Holding, LLC both plan to have portable toilets and hand washing facilities on the property during construction and will have septic systems at their offices, once constructed and building permits are applied for. A commercial well will be applied for and shared between Noble Energy and Wattenberg Holding. Bottled water and handwashing facilities will be provided for employees working at the site until the commercial well is in place. i. Sewage disposal system on the property (existing and proposed). There is no existing sewage disposal system on the property. Noble Energy and Wattenberg Holding, LLC both plan to have some portable toilets and hand washing facilities on the property during construction and for truck drivers coming to the site. They both plan to construct septic systems for each of their offices once they are ready to pull their building permits. If storage or warehousing is proposed, what type of items will be stored. Some outside storage of pipe and some oil and gas equipment will be on site. 6. Explain the proposed landscaping for the site. No landscaping is proposed for this facility for several reasons. First, there is no irrigation to the site to support landscaping. Second, vegetation can be a fire hazard at these types of facilities. The detention ponds will be re -seeded for erosion control. The undisturbed areas on the site will remain native and the remainder of the site will most likely be road base and rock in the process areas. Stockpiles of topsoil will be seeded to prevent blowing dust. Therefore, no landscaping is proposed and the native vegetation around the outside of the facility will remain. 5 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. 8. Explain how the storm water drainage will be handled on the site. Off -site flows will be routed around the site. On -site flows will be conveyed to on -site detention ponds, two for Noble Energy's facility and one for Wattenberg Holding's facility. The one -hundred year developed storm event will be released at the ten-year historic rate from the ponds. For more details, please see the attached Final Drainage Report. 9. Explain how long it will take to construct this site and when construction and landscaping is scheduled to begin. Noble Energy and Wattenberg Holding, LLC anticipate that it will take approximately nine to twelve months to construct the site. Construction should be complete by Fall of 2015. 10. Explain where storage and/or stockpiles of wastes will occur on this site. There will be no storage and/or stockpiles of waste 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. On -site improvements: • Joint access with turn radius of 60' from WCR 104, with tracking control. • There will be a shared, internal road for use by Noble Energy and Wattenberg Holding, LLC and their respective facilities. The internal road will be constructed with 3" or 6" road base. Anticipated completion: Fall, 2015 • Noble Energy and Wattenberg Holding, LLC will each fence their facilities with chain link fence around their perimeters and have security gates with lock boxes at the entrances to each of their facilities. The fire district will either be given a key or code, so that they can obtain access, if needed during an emergency. Anticipated completion: Fall, 2015 • Noble Energy and Wattenberg Holding, LLC will have their own detention and drainage structures for each of their facilities, as shown on the USR plat map and within the Final Drainage Report and Plans. Anticipated completion: Fall, 2015 • Overlot grading will be completed on the Noble Energy site and on the Wattenberg Holding, LLC site. Anticipated completion, Fall, 2015 • Landscaping is not being proposed for this facility. Off -site improvements: • No off -site improvements are anticipated at this time, since there is very little traffic associated with the property. During construction, water will be used for dust control, as needed. 6 it ) TETRA TECH August 14, 2014 Mr. Kim Ogle Weld County Planning Department 1555 N. 17th Avenue Greeley, CO 80631 RE: Noble EnergyNVattenberg Holding, LLC: East Pony Central Processing Facility Submittal of Use by Special Review and response to 7 day completeness questions Dear Kim: Please find one (1) complete hard copy of the items in the USR Application you requested, two (2) updated full-size copies of the USR plan set, and one (1) CD of the complete application for the East Pony Central Processing Facility application for Noble Energy and Wattenberg Holding, LLC.

Sunset #1-E Longmont, CO 80501 RE: Traffic Narrative for Noble Energy's East Pony Site Julie: I have estimated site traffic for the East Pony site in Weld County. The site is located on the south side of CR 104 just west of CR 115 (extended). The site will be used by Noble Energy and Wattenberg Holding for an oil and gas centralized processing facility. Specific traffic items are identified and discussed in the following sections of this letter. PROJECT OVERVIEW Noble Energy will convey oil, water, and gas to the site by pipeline. Once onsite, it will be treated, processed, and/or recycled before it leaves the site. For the most part, all products will arrive at and depart the site via pipeline. SITE TRAFFIC Short Term The centralized processing facility will operate 24 hours per day, seven days per week. It will have a total of six employees working on -site with Noble having five employees and Wattenberg having one employee. Noble will have two twelve hour shifts (6:00 AM - 6:00 PM) with Wattenberg having one shift from 6:00 AM - 4:00 PM. Large truck traffic is estimated at about 17 per day, most of which, will arrive and depart during daylight hours. This may increase by 5 - 10 trucks if it becomes necessary to truck water to a third party location. Under worst case conditions there will be 27 trucks per day arriving and departing the site. Truck arrivals and departures will occur randomly and are estimated at 1 - 2 per hour. Employee and miscellaneous site vehicles will typically be passenger cars or pickup trucks and will be in the range of 6 - 8 vehicles per day. In total, up to 35 vehicles per day are expected to visit the centralized processing facility. Site access will be from CR 104 with the primary access located some 670 feet west of CR 115 based on centerline spacing. Secondary access will be provided by an easement to the south of CR 104 which will generally align with CR 115. Sight distance at the primary access is about 1,000 feet or more. Sight distance at the secondary access will be increased as part of Noble's plan to improve this section of CR 104. Construction documents have been prepared by Baseline Engineering. Future sight distances and all other design features contained in the Baseline documents will be reviewed and approved by the County as part of its' review process. Essentially all vehicles arriving at and departing the site are expected to use SH 14, CR 105, and CR 104. All roadways except SH 14 are grave! roads. Long Term A truck unloading facility is contemplated on the East Pony site in the future. Such a facility will add up to 50 trucks per day. When the truck unloading facility is built, total site traffic will be 85 vehicles per day. IMPROVEMENTS No improvements will be warranted by the site traffic generated by the East Pony project. This was determined by a review of the following County numerical warrants for dust abatement and turn lanes. County dust abatement triggers for the various levels of treatment are stated below. These triggers will not be met by the daily traffic generated by the East Pony site: 200 vpd will require Mag-Chloride dust abatement 300 vpd alternative pavement as accepted by Public Works 400 vpd pavement Turn lanes will not be needed with this development since site traffic will not impede through traffic, and the number of peak hour turning vehicles will be below the following County triggers for higher speed roadways: 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 I trust this traffic narrative will meet your current needs. Please give me a call if you have any questions or need further assistance. Sincerely, 41-Mti---- Eugene G. Coppola, P.E., PTOE Weld County Public Works Dept. 1111 H Street P.O.

Emission calculations, emission factor documentation, O&M plans, facility wide emission inventory, notice of startup, and other applicable forms are included in this package. Noble requests all emission points be covered under a single facility -wide permit. This facility will process oil from area well sites as well as have the ability to further treat oil past -custody transfer, There will also be both electric and gas compression on -site to boost area gas gathering system pressures. As such, this facility could be considered an E&P site, a non-E&P site, or a compressor station. If there is a discrepancy in requirements, we will default to the most stringent requirement. Emission Points and Regulatory Analysis Engines NSPS JJJJ / MACT ZZZZ — All engines will be considered new for NSPS JJJJ and MACT ZZZZ applicability. - An O&M plan is included for the engines. Tank Battery (Oil and Produced Water) Regulation 7 — The tank battery is not located in the ozone nonattainment area and is therefore not subject to Section XII of the regulation. All other state-wide O&G sections apply. NSPS Kb — The storage tanks at the facility all have the potential to receive oil post custody transfer and are therefore subject to the regulation. All oil tanks will comply by having internal floating roofs. Produced water tanks have the potential to have a layer of skim oil and thus are considered oil tanks for Kb applicability. The produced water tanks will either have internal floating roofs or will be fixed roof routed to a closed loop control system. NSPS OOOO — All tanks are subject to NSPS Kb and are thus exempt from NSPS OOOO. The water handling portion of the facility is still in the design phase. The preference would be to have floating roofs on the produced. water tanks similar to the oil tanks as the floating roof tanks inherently have lower emissions. However, Noble is still researching the technical feasibility of incorporating an oil slimming system on a floating roof tank. Thus there is a possibility the produced water tanks will be fixed. roof. In this scenario, the produced water tanks would be controlled with a VRU with a flare backup in case of VRU downtime. The requested permit limit is based upon the maximum expected from any of the scenarios. An O&M plan is included for the produced water tanks. This plan will only apply if the fixed roof option is selected. All floating roof tanks will follow the floating roof requirements of NSPS Kb. Fugitives Regulation 7 — The facility subject to STEM and LDAR requirements of Regulation 7 Sections XVIl.C. and XVII.F. A monthly leak monitoring program meets these requirements. As such, an individual O&M plan is not submitted. Beaters Regulation 3 — The heaters arc all less than 5 mmbtuh and thus are exempt from APEN and permitting requirements per Regulation 3 Part A ILD1,ggg. Emission estimates arc still presented to provide data on insignificant activities. Emergency Generator NSPS 111I — The diesel generator meets all the emergency generator requirements for NSPS IIII. It is not intended for this engine to operate greater than 250 hours per year, thus the engine is APEN required, but permit exempt. I miscalculated my APEN fees when requesting a check. The additional required APEN fee may either be billed with the permit fees at a later date or immediately charged to my credit card. Should there be any questions concerning this application, I can be contacted at the letterhead address above, directly by phone at (303) 228-4150, or by e-mail at eflanders(canobleenergvine.com.

It should be used with the Caterpillar Fuel Usage Guide for the engine and rating to determine the rating for the fuel specified. A Fuel Usage Guide for each rating Is included on page 2 of its standard technical data sheet. RPC always applies to naturally aspirated (NA) engines, and turbocharged (TA or LE) engines only when they are Berated for altitude and ambient site conditions. Project specific technical data sheets generated by the Caterpillar Gas Engine Rating Pro program take the Caterpillar Methane Number and RPC into account when generating a silo rating. Fuel properties for Btu/sof calculations areal 61F and 14.696 psin. Caterpillar shall have nn liability In law or equity, for damages, consequently or otherwise, arising from use of program end related material or any part thereof. FUN LIQUIDS Hole gases, well head gases, and associated gases typically contain liquid water and heavy hydrocarbons entrained In the gas. To prevent detonation and severe damage to the engine, hydrocarbon liquids must not be allowed to enter the engine fuel system. To remove liquics, a liquid separator and coalescing filter are recommender, with an automatic drain and collection tank to prevent contamination of the ground in accordance with local codes and standards. To avoid water condensation in the engine or fuel lines, limit the relative humidity of water in the fuel to 80% at the minimum fuel operating temperature.

Assume Gasoline RVP 12 as a conservatively high estimate, Facility is designed for a maximum of 125K BOPD processed. The various tank sizes are present for operational flexibility. Emissions from floating roof tanks are based primarily on seal and fitting losses, Throughput has a minimal affect on total emissions, therefore total oil storage tank emission factors are to be based upon lb/hr rather than lb/bbl. The throughputs listed for each tank size are reasonable averages for that tank size for EPA Tanks model runs only, Individual modeled throughputs are not cumulative, Total throughput for the facility will not exceed 125K BOPD. Requested permit limits are for all oil storage tanks combined. Throughput through individual tanks will not be tracked. *Nominal working capacity. Total design capacity as defined by Kb will be higher *Tanks are still in design phase and dimensions are subject to change. This source is subject to NSPS Kb and thus exempt from NSPS OOOO.

Total design capacity as defined by Kb will be higher 'Tanks are still in design phase and dimensions arc subject to change. This source Is subject to NSPS Kb and thus exempt from NSPS 0000. The water tanks have the potential to have an accumulation of oil on the surface. Given the size of the tanks, they will be treated as oil tanks for Kb applicability purposes. Requested permit limits are for all oil storage tanks combined. Throughput through Individual tanks will not be tracked. The water handling system Is still in design phase. Emissions have been estimated using three scenarios: 1) Large Internal floating roof tanks with Internal skim box - no flash emissions 2) Smaller Internal floating roof tanks with internal skim box - no flash emissions 3) Large or small fixed roof tanks with potential for flash emissions Emission estimates for the IFRT scenarios are straight forward using EPA Tanks assuming the tank contents are oil but using the water throughput. There Is no additional control on fixed roof tanks. Emission estimates for the fixed roof scenario use the APCD default produced water emission factors. The control scheme In this scenario would be a primary VRU with a secondary flare or combustor. The % runtime of the VRU Is then adjusted to approximately match the 40K IFRT scenario. A requested permit limit of 6 tpy is sufficient to cover all three scenarios.

It applies to permits subject to Regulation NNo. 3 Part. B, §III.B.5.d (100103agccstationarysourcepermitting.pdf) and to general permits that have an "impact analysis" requirement, It applies to sources emitting particulate matter, carbon monoxide, lead, sulfur dioxide, or nitrogen oxides. Sources emitting only volatile organic compounds (VOCs) should disregard this form. 1. ❑ Submit a complete Air Pollutant Emission Notice (APEN) form and all other required APEN forms arc available at: http://www.cdphe.state.co.us/ap/stationarv.hanl forms. 2.

Gas -fired compressor engines will bring nearby gas from the gathering system for booster compression to area gas plants or pipeline sales. Pressurized crude oil will be delivered via pipeline to the East Pony Processing Facility. The rate is estimated to peak at 125,000 BOPD. Crude oil will initially be delivered to a free water knock out (Qty up to 8). If it is out of pipeline specifications, once it has left the FWKO, the oil will be processed in gas fired heater treaters for final oil / water separation. These heater treaters (Qty up to 8) will be less than 5,000,000 btu/hr. Oil will then be staged in pressurized bullet tanks for flow control. Oil will be pumped from the bullet tanks through stabilizing towers to get the RVP to the pipeline specifications. As a result of this stabilization, a gas stream will come off the top of the stabilizing towers, be compressed by electric vapor recovery units, and sent down line to gas sales. An NGL stream may also be generated and sent to the bullet tanks for load out / truck sales. There will be no emissions associated with the NGL stream as the system is pressurized. Stabilized oil will be sent to floating roof tanks for storage prior to sale via pipeline. We have planned two 250,000 bbl tanks, six 40,000 bbl tanks and four 5,000 bbl tanks. Additionally there will be two 5000 - 40,000 bbl produced water tanks for production water as well as water recovered from the FWKO and Heater / Treaters. The produced water tanks will either be floating roof with an internal oil skim system or they will be fixed roof with a VRU / flare closed loop control system. An emergency / blow down flare will be located on site as well and is expected to only run during emergency / blow down situations. Additional exempt sources such as electric compression, fresh water ponds, and recycled water storage may be located on site. . 0 co LL O) i . U) V J W O 2. I.L..

With development of a green field site, one can expect an increase in impervious cover and, therefore, an increase in peak storm water runoff. This report examines the undeveloped flow patterns of off -site and on -site drainage basins and the proposed storm water facilities designed to mitigate the downstream impact of increased storm water runoff. The contents of this report are prepared, at a minimum, in accordance with the Weld County Code for a Final Drainage Report. 2.0 GENERAL LOCATION AND DESCRIPTION 2.1 Location and Existing Conditions The East Pony Central Processing Facility site is located on an approximately 79.94 acre parcel approximately 5.7 miles east-northeast of the Town of Keota, Colorado, adjacent to and west of Weld County Road (WCR) 115 and adjacent to and south of WCR 104. More specifically, the subject property is located in the northeast corner of Section 21, Township 9 North, Range 59 West of the 6th P.M., Weld County, Colorado. A vicinity map has been provided in Appendix A. The property is currently undeveloped and consists of agricultural rangeland. Surrounding land use adjacent to the subject parcel is primarily rangeland for livestock grazing. Other hydrocarbon production wells are present on adjacent properties. An existing natural gas pipeline traverses the site near the northern property boundary. Another existing gas line on a northwest -southeast trend is located at the northeast corner of the property. A power line is present near the eastern property boundary and is approximately 30 feet west of the section line. WCR 104 is a publicly maintained road within dedicated County right of way. WCR 115 has a dedicated County right of way. The road located within WCR 115 right of way is a private road and is not maintained by the County. 2.2 Proposed Development Noble Energy and Wattenberg Holding are proposing an oil and gas central processing facility. Noble Energy will own the property and Wattenberg Holding will lease a portion of the site from Noble Energy. Future facilities at the Noble Energy site may include freshwater storage ponds fed by a pipeline from a well at a remote site. The Wattenberg Holding portion of the site is located in the southeastern quadrant of the facility. Future facilities in Wattenberg Holding's tract may include a truck unloading facility. Detailed discussion of both facilities uses is included in the USR application. There is one proposed access point from WCR W4 onto the site. There will be informational signs at the entrances to direct traffic. Final Drainage Report East Pony Central Processing Facility l July 2014 F:G57 19A133-35719-14007ADues \ Reports \FINAL DRAIN AG@AFinal Drainaee Report_hastl'ony.doe 3.0 DRAINAGE BASINS AND SUBBASINS 3.1 Major Basin Description The subject property is located in rural Weld County and is surrounded by undeveloped agricultural rangeland. The project site lies in a FEMA designated area, Zone D: "no analysis of flood hazards has been conducted." The Weld County Map Index is provided in Appendix A. The East Pony facility is located in Flood Insurance Rate Map (FIRM), Community Panel No. 0802660425C. This map panel is not published, which indicates that no FEMA designated floodplains have been identified. The site is located outside any applicable Weld County or adjacent Master Drainage Plans. The site is located within a watershed that generally flows southeast towards Wild Horse Creek. According to the Soil Survey of Weld County, Colorado, Northern Part [1 ], site soils are primarily silty loam with some sandy loam. Loam soils are generally well drained and slopes are between 0 and 9 percent. The soils in the drainage basins surrounding the project site are primarily sandy hams and hams with slopes generally ranging between 0 and 9 percent. A detailed soil survey report has been provided in Appendix B-1. The soil types are predominantly hydrologic soil group B, with some type A and type D soils located in at the periphery off the offsite basins. 3.2 Historic Drainage Patterns Minor ridge lines divide the site into three historic sub -basins: Basin A, Basin B and Basin C. Basins A and B consists of the northern portion of the watershed and drains southeast towards a tributary to Wild Horse Creek. Basins A and B were delineated in order to determine separate flows for onsite drainage features. While USGS topography shows that there is a stream along the eastern property boundary, field topographic survey shows no such stream. Aerial photography does show that a stream is present east of the project site. The lack of a defined stream on the project site combined with the magnitude of the peak runoff leads us to assume that runoff concentrates at the intersection and overtops the roads. Overtopping flow is presumably split between the project site and the property east of the project site. Basin A is located north of the project site and drains to the intersection of WCR 104 and WCR 115. An existing roadside ditch along the north side of Weld County Road 104 also intercepts some of the storm water runoff from Basin A. Existing topography shows that flows from Basin A flow through a small portion of the site area at the northeast corner. Basin B is located in the middle of the project area. Runoff from Basin B flows south east towards Wild Horse Creek and the existing roadside ditch along the north side of Weld County Road 104. Runoff from Basin B flows from the northwest corner, southeast across the entire project site. Basin C is located in the southern part of the project area and flows southeast towards Wild Horse Creek. Basin C flows across the project site from the west to the southeast corner of the site. Site rainfall depth information was obtained from the National Oceanic and Atmospheric Administration (NOAA) Atlas 14, Volume 8, Precipitation -Frequency Atlas of the United States Final Drainage Report East Pony Central Processing Facility 2 July 2014 P935719 \ 133-35719-14007 \ Dues \ Reports \ FINAL DRAIN AG@AFinal Drainaee Report_hastpony.doe (2013). This data supersedes the rainfall depth information provided in the Urban Storm Drainage Criteria Manual. The current NOAA data was used for the determination of point rainfall data. The NOAA data formed the basis of the IDF calculations for other storm frequencies and durations using Urban Drainage methods. Rainfall data is presented in Appendix B-2. Historic runoff coefficients are calculated for each site soil type using the methods detailed in the Urban Storm Drainage Criteria Manual, Volume 1, Ch. 5. Because the areas of drainage basins B and C are less than 160 acres, the Rational Method was used to analyze the historic peak flows. Historic runoff coefficients and peak flows for the 10 -year and 100 -year storm events for drainage areas B and C have been provided in Table I . Times of concentration for Basins B and C were estimated using the methods detailed within Urban Storm Drainage Criteria Manual, Volume I, Ch. 5. Basin A exceeded 160 acres, so the NRCS Curve Number method was used to estimate peak runoff. HEC-HMS was used to estimate the flow. Time of concentration for Basin A was estimated using the time of concentration methods detailed within Urban Storm Drainage Criteria Manual, Volume I, Ch. S. HEC-HMS uses the lag time, defined as 0.6 times the time of concentration, as input for calculation of the hydrograph. The Curve Number was estimated using the values for semi -arid rangeland that is presented in Table 2-2d of the NRCS TR-55 Urban Hydrology for Small Watersheds publication. A composite CN accounting for land use and hydrologic soil group was estimated. The composite CN for Basin A was estimated as approximately 8I I. Calculations for time of concentration and composite CN for the HMS analysis is presented in Appendix B-3. Table 1: Historic Basin Runoff Summary Peak Flow Peak Flow Corresponding Basin ID Acres 10-yr (cfs) 100-yr (cfs) POA A 520.10 131 385 A B 110.78 30.88 114.63 B C 136.00 38.99 143.18 C The values presented in the preceding table are the maximum allowable 10 -year historic discharges that may be discharged from the site per County code. Detailed historic drainage calculations are provided in Appendix B-3. 3.3 Off:Site Drainage Patterns Basin A will remain unchanged as a result of the project. Runoff from Basin A will be conveyed south along the eastern property boundary to connect to a proposed culvert. Basin A will discharge at Point of Analysis (POA) A, but will be conveyed unchanged to POA B. Off -site drainage basin, O-2, is located north of the subject property and is approximately 104.4 acres. Basin O-2 is a subdivision of historic Basin B. Basin O-2 drains to the eastern property boundary in the same location as Basin B. Basin O-2 was considered to be essentially undeveloped. The proposed site does show some improvements that may be constructed, such as an access road within the site. Due to the relatively small acreage of the road (approximately 1.05 acres) compared Final Drainage Report East Pony Central Processing Facility 3 July 2014 P:A35719A133-35719-14007ADots\ReportsAFINAL DRAINAGEVFinal Drainage Repuri_FastPuny.doc to the overall watershed area, the increase in runoff due solely to the road is expected to be insignificant. Two fresh water storage ponds are also proposed. The ponds are proposed as future construction. The ponds are anticipated to be partially above and below grade. As a result of anticipated configuration, the ponds will capture and contain rainfall that falls directly into it. If the ponds are constructed, it is anticipated that they will lower the peak flows from Basin O-2. Basin O-2 will be conveyed under the access road and the private road within the WCR 115 right of way by two culverts. Basin O-2 will discharge at POA B. The runoff coefficient for Basin O-2 is the same as Basin B. Off -site drainage basin, O-3 is located west of the subject property and is approximately 97.55 acres. Basin O-3 is a subdivision of historic basin C. The runoff will be intercepted by a drainage ditch located along the western property boundary and discharged off site at POA C. The runoff coefficient for Basin O-3 is the same as Basin C.

Off -site drainage calculations are provided in Appendix B-4. 4.0 DRAINAGE DESIGN CRITERIA This report is prepared in compliance with the Urban Storm Drainage Criteria Manual, Volumes 1, 2 and 3; Weld County Code; and the Weld County Storm Drainage Criteria Addendum to the Urban Storm Drainage Criteria Manuals Volumes 1, 2, and 3. Based on this criterion, a 100 -year storm is used as the major stone when evaluating existing and proposed drainage facilities. Rainfall Data: Data for the 6 -hour and 24 -hour storm event was collected using the Volume 8, Precipitation -Frequency Atlas of the United States (2013). Rainfall data was then converted to I - hour rainfall data using Urban Drainage and Flood Control District's (UDFCD's) UD-RainZone v1.01 spreadsheet. Pipe and Culvert Sizing: Site storm infrastructure capacities have been evaluated using Manning's Equation. The culverts on site are sized to convey the 100 -year storm event. Additionally, the outlet pipes from each detention pond are sized for a specific release rate of the 10 -year historic flow with the use of an orifice plate. Erosion control devices will be provided at all culvert and swale outlets to protect against downstream erosion. Culvert sizes were determined using Culvertmaster software. Preliminary pipe calculations have been provided in Appendix C-1. Drainage Channel Sizing: A drainage channel is proposed along the southwest side of the project site to route offsite flows along the west side of the site. Additional channels are present on the site to Final Drainage Report East Pony Central Processing Facility 4 July 2014 P935719A133-35719-14007ADues \ Reports \FINAL DRAIN AG@AFinal Drainaee Report_hastl'ony.doe channel flows to the detention ponds. All channels are sized for the 100 -year storm event using Manning's Equation. Multiple on -site drainage channels have also been sized to convey the major storm event. Detailed channel calculations have been provided in Appendix C-2. Due to the fire danger at the site, much of the developed section of the site will be unvegetated, including drainage channels. Detention ponds may be vegetated. Due to the relative steepness of channels and the soil types, turf reinforcement mat is recommended for all drainage channels and pond slopes to reduce erosion potential. Water Quality Pond Sizing: A water quality pond is required prior to releasing stormwater runoff from the development. The water quality pond has been sized for the 25-yr developed stone event in accordance with Noble Energy's operational procedures for mitigation of stormwater runoff from this industrial site. This volume is in excess of the mandated WQCV. This water quality pond will include a water quality orifice plate on the outlet structure in accordance with the Urban Storm Drainage Criteria Manual. Water quality pond sizing for the Wattenberg Holding ponds will be calculated in accordance with the Urban Storm Drainage Criteria Manual. Detailed water quality pond sizing information is presented in Appendix C-3. Detention Pond Sizing: The detention pond volume has been determined using the UDFCD's Detention Design — UD-Detention v2.34. Detention Ponds Noble 201 and Noble 301 will detain the 100 -year developed storm event from the Noble portion of the site. Detention Pond Watt 101 and Watt 201 will detain the 100 -year develop storm event from the Wattenberg Holding portion of the site. Detention Pond Watt 101 will serve only as a Detention Pond. Detention Pond Watt 201 will function as both the detention pond and secondary containment for spills for a portion of the Wattenberg Holding site. Detention ponds will be configured to release no more than the 10 -year historic flow at the points of analysis in accordance with Weld County criteria. A minimum of one -foot of freeboard will be provided. The required water quality capture volume win be contained within the detention volumes for each pond. An emergency spillway, in the form of a trapezoidal weir, is proposed to convey the 100 -year flow rate at a 6 -inch depth. Detailed detention pond calculations have been provided in Appendix C-4. 5.0 DRAINAGE FACILITY DESIGN 5.1 General Concept Noble Energy and Wattenberg Holding will have separate drainage facilities that are contained within their respective portions of the project site. Basins designated with an "N" prefix are on the Noble Energy section of the property. Basins designated with a "W" prefix are on the Wattenberg Holding section of the property. Historic Basin A will drain unchanged through the site and overland into the property adjacent to the east. Basin A runoff concentrates at the road intersection and is assumed to overtop the roads. Overtopping flows are expected to disperse and follow the general trend of the topography to the Final Drainage Report East Pony Central Processing Facility 5 July 2014 P935719A133-35719-14007ADues \ Reports \FINAL DRAIN AG@AFinal Drainaee Report_hastl'ony.doe southeast. Due to the uncertain nature of the Basin A runoff, no attempt will be made to channelize or otherwise contain this flow. The developed condition of the site is divided into four major drainage basins: N201, N30I, W101, and W201. Basin N301 is further subdivided into nine sub -basins. Basin N201 is subdivided into two sub -basins. Basin W101 is divided into 3 sub basins. Basin N201 will flow overland to Detention Pond N201. The detention pond will drain to a culvert under the access road and then through another culvert under Weld County Road 115. Basin N201 flows are associated with POA B. Basin N301 will drain through a network of drainage ditches to the N301 detention pond. The detention pond will drain directly to natural grade near the property boundary. Basin N301 flows are associated with POA C. Basin W101 will flow through drainage channels into the W101 detention pond.

The basin is graded to drain into Pond N201. All runoff reaches Pond N201 as overland flow. Drainage Basin N301 includes the majority of Noble Energy processing facility equipment, including heaters, stabilizing towers, compressors, a transfer pump, bullet tanks, and other oil and gas processing equipment. Basin N301 was subdivided into several sub -basins for the sizing of tributary channels and Culvert 301. Tributary drainage channels collect runoff from the basin and into a main channel that flows into Detention Pond N301. Basin N301k includes the secondary containment for Noble's oil storage facilities. There is a direct pipe connection between Basin N301 k and the detention pond. The secondary containment release will be valved and actively managed by the onsite operator. Future facilities are included in impervious area calculations. Drainage Basin W101 encompasses the supporting facilities of Wattenberg Holding's operations, including offices, equipment storage areas, and other supporting facilities. Buildings are generally located within Basin W101a. Basin W101b will be released directly offsite without detention due to the physical constraints of the site layout. Basin W 101c is a small sub -basin which drains a portion of the loop access road. Each sub -basin drains into Detention Pond WI 01. Equipment storage areas are planned to have a gravel surface. A future truck unloading facility may be constructed and is included in impervious area calculations. Drainage Basin W201 encompasses hydrocarbon storage and equipment and includes secondary containment for these facilities. The secondary containment will also function as a detention pond. The secondary containment detention pond release will be valved and actively managed by the onsite operator. Consideration was given to combining detention facilities for Basins W I01 and W20I . However, the desired grading and finished floor elevations physically prevented combination of the two ponds. Table 5 provides the peak flow rates for the sub -basins of each of the major basins.

Channel N302 will convey the offsite flows to the south, returning the runoff to overland flow near the southern property boundary. Channel N302 conveys runoff to POA C. Detailed channel calculations are provided in Appendix C-2. 5.4 Water Quality The proposed water quality features for the site are water quality capture ponds. Water quality capture volume (WQCV) for Basin N201 will be located within Detention Pond N201. WQCV for Basin N301 will be located within Detention Pond N301. WQCV for Basin W101 will be located within Detention Pond W101. WQCV for Basin W201 will be located within Detention Pond W201. The water quality volumes for all of the detention ponds are sized in accordance with the Urban Storm Drainage Criteria Manual, Volume 1-3 and the water quality features are designed to handle the runoff from the developed portions of the site. Developed runoffflows are designed to route through the water quality feature. Per Urban Storm Drainage Standards, 120% of the water quality volume will be provided. The proposed water quality volume drain time is 40 hours. A perforated plate is proposed as the water quality feature for each pond. The WQCV is included in the detention pond volumes for each of the drainage basins. WQCV calculations are presented in Appendix C-3. A storage volume summary is provided below in Table 6.

The maximum release rate to POA C, which includes the combined discharges from N301, W101, and W201, is 7.94 cfs. Pond N201 is used to detain runoff from Basin N201, which generally encompasses Noble Energy's office facilities. The maximum outflow rate of the pond was set to 1.82 cfs in the Urban Drainage calculation spreadsheet. Pond N301 is used to detain runoff from Basin N301, which encompasses the majority of Noble Energy's processing equipment. The maximum outflow rate of the pond was set to 5.0 cfs in the Urban Drainage calculation spreadsheet. Separate calculations for total basin imperviousness and time of concentration were determined for the overall basin draining to the pond. Pond W I01 is used to detain runoff from Basin W 101, which encompasses Wattenberg Holding's office facilities. The maximum outflow rate of the pond was set to 2.0 cfs. This rate was selected in order to use the maximum detention volume of the space designated for the detention pond by the facility designer. Pond W201 is used to detain runoff from Basin W201, which encompasses Wattenberg Holding's storage tanks. Pond W201 is also used for secondary containment for the tanks. As a result, the volume of the pond is significantly larger than needed for runoff detention. In order to prevent an accidental oil spill from leaving the site, the outlet for Pond W201 will be closed at all times until it can be opened to release water. The maximum outflow rate of the pond was set to 0.94 cfs. Calculations show that the total storm volume is approximately 1.116 ac -ft. The total volume of the secondary containment is approximately 18.08 ac -ft. The pond has sufficient volume to contain both 110% of the largest tank and a 100 -year, 1 - hour storm. A summary of the required detention volumes is presented in the following table. The combined outflow for Ponds N30I, W101, and W201 are 7.94 cfs, which is the maximum outflow allowable for POA C.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/portal/ nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (http:// offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nres142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil -vegetation -landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil scientists classified and named the soils in the survey area, they compared the 5 Custom Soil Resource Report individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil - landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil -landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field -observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. 6 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If 94.7% 5.3% 100.0% 10 Custom Soil Resource Report intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha - Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 11 Custom Soil Resource Report Weld County, Colorado, Northern Part 31 —Kim -Mitchell complex, 0 to 6 percent slopes Map Unit Setting Elevation: 3,500 to 6,500 feet Mean annual precipitation: 11 to 17 inches Mean annual air temperature: 46 to 54 degrees F Frost -free period: 120 to 160 days Map Unit Composition Kim and similar soils: 45 percent Mitchell and similar soils: 40 percent Minor components: 15 percent Description of Kim Setting Landform: Alluvial fans, plains Down -slope shape: Linear Across -slope shape: Linear Parent material: Calcareous loamy alluvium Typical profile H1 - 0 to 3 inches: moderately alkaline, loam H2 - 3 to 7 inches: moderately alkaline, clay loam H3 - 7 to 60 inches: moderately alkaline, loam Properties and qualities Slope: 0 to 6 percent Depth to restrictive feature: More than 80 inches Natural drainage class: Well drained Capacity of the most limiting layer to transmit water (Ksat): Moderately high (0.20 to 0.60 in/hr) Depth to water table: More than 80 inches Frequency of flooding: None Frequency of ponding: None Calcium carbonate, maximum in profile: 15 percent Salinity, maximum in profile: Nonsaline to very slightly saline (0.0 to 4.0 mmhos/cm) Available water storage in profile: High (about 9.7 inches) Interpretive groups Farmland classification: Farmland of statewide importance Land capability classification (irrigated): 4e Land capability classification (nonirrigated): 4e Hydrologic Soil Group: B Ecological site: Loamy Plains (R067BY002CO) Description of Mitchell Setting Landform: Alluvial fans, plains Down -slope shape: Linear Across -slope shape: Linear Parent material: Calcareous loamy alluvium 12 Custom Soil Resource Report Typical profile H1 - 0 to 7 inches: moderately alkaline, silt loam H2 - 7 to 60 inches: moderately alkaline, silt loam Properties and qualities Slope: 0 to 6 percent Depth to restrictive feature: More than 80 inches Natural drainage class: Well drained Capacity of the most limiting layer to transmit water (Ksat): Moderately high to high (0.57 to 5.95 in/hr) Depth to water table: More than 80 inches Frequency of flooding: None Frequency of ponding: None Calcium carbonate, maximum in profile: 15 percent Available water storage in profile: High (about 10.8 inches) Interpretive groups Farmland classification: Farmland of statewide importance Land capability classification (irrigated): 4e Land capability classification (nonirrigated): 4e Hydrologic Soil Group: B Ecological site: Siltstone Plains (R067BY009CO) Minor Components Haverson Percent of map unit: 5 percent Thedalund Percent of map unit: 5 percent Keota Percent of map unit: 5 percent 47 —Otero sandy loam, 3 to 9 percent slopes Map Unit Setting Elevation: 4,500 to 5,500 feet Mean annual precipitation: 12 to 15 inches Mean annual air temperature: 48 to 52 degrees F Frost -free period: 130 to 180 days Map Unit Composition Otero and similar soils: 85 percent Minor components: 15 percent Description of Otero Setting Landform: Fans, plains 13 Custom Soil Resource Report Down -slope shape: Linear Across -slope shape: Linear Parent material: Calcareous loamy alluvium and/or colluvium Typical profile H1 - 0 to 5 inches: moderately alkaline, sandy loam H2 - 0 to 5 inches: moderately alkaline, sandy loam H2 - 0 to 5 inches: moderately alkaline, sandy loam Properties and qualities Slope: 3 to 9 percent Depth to restrictive feature: More than 80 inches Natural drainage class: Well drained Capacity of the most limiting layer to transmit water (Ksat): Moderately high to high (0.57 to 5.95 in/hr) Depth to water table: More than 80 inches Frequency of flooding: None Frequency of ponding: None Calcium carbonate, maximum in profile: 10 percent Salinity, maximum in profile: Nonsaline to very slightly saline (0.0 to 4.0 mmhos/cm) Available water storage in profile: Very high (about 14.8 inches) Interpretive groups Farmland classification: Not prime farmland Land capability classification (irrigated): None specified Land capability classification (nonirrigated): 6e Hydrologic Soil Group: B Ecological site: Sandy Plains (R067BY024CO) Minor Components Stoneham Percent of map unit: 7 percent Kim Percent of map unit: 3 percent Bushman Percent of map unit: 3 percent Mitchell Percent of map unit: 2 percent 14 References American Association of State Highway and Transportation Officials (AASHTO). 2004.

Inadequate protection at conduit and culvert outlets has long been a major problem. The designer should refer to Section 4.4 for additional information on major drainage applications utilizing riprap. In addition, the criteria and guidance in Section 4.4 may be useful in design of erosion protection for conduit outlets. The reader is referred to Section 7.0 of the HYDRAULIC STRUCTURES chapter of this Manual for information on rundowns, and to Section 3.0 of the HYDRAULIC STRUCTURES chapter for additional discussion on culvert outfall protection. Scour resulting from highly turbulent, rapidly decelerating flow is a common problem at conduit outlets. The riprap protection design protocol is suggested for conduit and culvert outlet Froude numbers up to 2.5 (i.e., Froude parameters Q/d025 or Q/WH15 up to 14 ft°5/sec) where the channel and conduit slopes are parallel with the channel gradient and the conduit outlet invert is flush with the riprap channel protection. Here, Q is the discharge in cfs, d° is the diameter of a circular conduit in feet and W and H are the width and height, respectively, of a rectangular conduit in feet. 7.1 Configuration of Riprap Protection Figure MD -25 illustrates typical riprap protection of culverts and major drainageway conduit outlets. The additional thickness of the riprap just downstream from the outlet is to assure protection from flow conditions that might precipitate rock movement in this region. 7.2 Required Rock Size The required rock size may be selected from Figure MD -21 for circular conduits and from Figure MD -22 for rectangular conduits. Figure MD -21 is valid for Q/D,z5 of 6 or less and Figure MD -22 is valid for QNN-I' 5 of 8.0 or less. The parameters in these two figures are: 1. Q/D15 or QNW-i°.5 in which Q is the design discharge in cfs, D, is the diameter of a circular conduit in feet, and Wand H are the width and height of a rectangular conduit in feet. 2. Y,/DC or Y,/H in which y is the tailwater depth in feet, D, is the diameter of a circular conduit in feet, and H is the height of a rectangular conduit in feet. In cases where Y is unknown or a hydraulic jump is suspected downstream of the outlet, use Y,/D, = Y,/H = 0.40 when using Figures MD -21 and MD -22. Rev. 04/2008 Urban Drainage and Flood Control District MD -103 MAJOR DRAINAGE DRAINAGE CRITERIA MANUAL (V. 1) 3. The riprap size requirements in Figures MD -21 and MD -22 are based on the non -dimensional parametric Equations MD -18 and MD -19 (Steven, Simons, and Lewis 1971 and Smith 1975). Circular culvert: d Y -ts s t D"D—=0.023 Rectangular culvert: 'd "Y so r H H�—_0.014 Q WH (MD -18) (MD -19) The rock size requirements were determined assuming that the flow in the culvert barrel is not supercritical. It is possible to use Equations MD -18 and MD -19 when the flow in the culvert is supercritical (and less than full) if the value of D, or H is modified for use in Figures MD -21 and MD -22. Whenever the flow is supercritical in the culvert, substitute Dafor D, and Ha for H, in which Da is defined as: D = �D,+Yn) a2 in which the maximum value of Da shall not exceed D, and H +Yn) Ha in which the maximum value of Ha shall not exceed H, and: Da = parameter to use in place of D in Figure MD -21 when flow is supercritical D, = diameter of circular culvert (ft) Ha = parameter to use in place of H in Figure MD -22 when flow is supercritical H = height of rectangular culvert (ft) Y = normal depth of supercritical flow in the culvert (MD -20) (MD -21) MD -104 04/2008 Urban Drainage and Flood Control District DRAINAGE CRITERIA MANUAL (V. 1) MAJOR DRAINAGE 7.3 Extent of Protection The length of the riprap protection downstream from the outlet depends on the degree of protection desired. If it is necessary to prevent all erosion, the riprap must be continued until the velocity has been reduced to an acceptable value. For purposes of outlet protection during major floods, the acceptable velocity is set at 5.5 ft/sec for very erosive soils and at 7.7 ft/sec for erosion resistant soils. The rate at which the velocity of a jet from a conduit outlet decreases is not well known. For the procedure recommended here, it is assumed to be related to the angle of lateral expansion, 0, of the jet. The velocity is related to the expansion factor, (1/(2tan0)), which can be determined directly using Figure MD -23 or Figure MD -24 assuming that the expanding jet has a rectangular shape: where: and: where: Lp = 7 1 \' 4 -W 2tanO, Y Lp = length of protection (ft) W = width of the conduit in (ft) (use diameter for circular conduits) Yt = tailwater depth (ft) 0 = the expansion angle of the culvert flow _Q V Q = design discharge (cfs) V = the allowable non -eroding velocity in the downstream channel (ft/sec) A, = required area of flow at allowable velocity (ft2) (MD -22) (MD -23) In certain circumstances, Equation MD -22 may yield unreasonable results. Therefore, in no case should Lp be less than 3H or 3D, nor does Lp need to be greater than 10H or 10D whenever the Froude parameter, Q/WH' 5 or Q/D25, is less than 8.0 or 6.0, respectively. Whenever the Froude parameter is greater than these maximums, increase the maximum Lp required by IA D, or IA H for circular or rectangular culverts, respectively, for each whole number by which the Froude parameter is greater than 8.0 or 6.0, respectively. Rev. 04/2008 Urban Drainage and Flood Control District MD -105 MAJOR DRAINAGE DRAINAGE CRITERIA MANUAL (V. 1) 7.4 Multiple Conduit Installations The procedures outlined in Sections 7.1, 7.2, and 7.3 can be used to design outlet erosion protection for multi -barrel culvert installations by hypothetically replacing the multiple barrels with a single hydraulically equivalent rectangular conduit. The dimensions of the equivalent conduit may be established as follows: 1. Distribute the total discharge, Q, among the individual conduits. Where all the conduits are hydraulically similar and identically situated, the flow can be assumed to be equally distributed; otherwise, the flow through each barrel must be computed. 2. Compute the Froude parameter Q/Dd25 (circular conduit) or Q;/W;H;15 (rectangular conduit), where the subscript i indicates the discharge and dimensions associated with an individual conduit. 3. If the installation includes dissimilar conduits, select the conduit with the largest value of the Froude parameter to determine the dimensions of the equivalent conduit. 4. Make the height of the equivalent conduit, H,, equal to the height, or diameter, of the selected individual conduit. 5. The width of the equivalent conduit, Wes, is determined by equating the Froude parameter from the selected individual conduit with the Froude parameter associated with the equivalent conduit, Q/W,,H,15 MD -106 04/2008 Urban Drainage and Flood Control District DRAINAGE CRITERIA MANUAL (V. 1) MAJOR DRAINAGE 2 OO .2 .4 .6 Yt/D ette FAQ J$�0.-4.
