Explain in detail, the proposed use of the property. The oil and gas market is continuing to expand in Weld County. The applicant, Blue Grama Land Corporation (Blue Grama), proposes to use a 73+/- acre parcel as a Truck Unloading and Oil and Gas Support Facility as defined in the Weld County Code. The Lucerne Origination Facility will be the origination point for the Grand Mesa Pipeline. Blue Grama has commitments from key industry producers to transport crude oil from Weld County to Cushing, Oklahoma. From Cushing, the resource is piped for refinement before being sent to other domestic and international destinations. A communications tower that will not exceed 70' in height is proposed for the southwestern portion of the property. The site is located south of and adjacent to Weld County Road 66 and west of and adjacent to Weld County Road 45. The site is located in part of the east half of the northeast quarter of Section 27, Township 6 North, Range 65 West of the 6th P.M., Weld County, Colorado. A Recorded Exemption and Subdivision Exemption are being processed concurrently with this USR request. The facility will operate 24 hours a day, 7 days a week, 365 days a year. The total number of employees at this facility will not exceed 8 employees. Initially, there will be one eight-hour shift with employees taking on-call times for off- hour work. Additional shifts may be added in the future. The site will be secure and fenced with chain link and topped with barbed or concertina wire. Access to the facility will be controlled by an automated access system. During daylight hours, the main gates may be left open to enable more efficient access to the facility. The facility will be secured during other times. Lighting will be for security purposes and shall not spill onto adjacent properties. Lighting standards are illustrated on the USR maps but placement will not occur until final construction is completed and security needs are identified. Traffic generation, site access and the proposed site improvements/structures are discussed in further detail elsewhere in this questionnaire. There are other permits that Blue Grama will be submitting 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 application submittal and evidence the application was received by the State of Colorado are included with this USR Application submittal. A Secondary Containment and Unloading Pad Plan will be provided 30 days prior to construction of that portion of the facility, as applicable. Initially, Blue Grama anticipates that 1/3 of the inbound product will be received by truck and 2/3 of the inbound product will be received by 3rd party pipeline connections. It is anticipated the number of trucks using the facility may decrease as piping infrastructure to the facility increases. 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 Weld County. Below is a list of 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. 0G.Goal 3 : Prevent surface and groundwater contamination from oil and gas minerals exploration and extraction. The proposed Lucerne Station is a new facility in an area of Weld County experiencing increased oil and gas activities. The proposed facility will support the industry by transporting material to Cushing where it is then transported to refineries for processing. The market has directed the need for this proposed facility. The proposed facility will minimally impact the surrounding properties. Surrounding properties include unincorporated Weld County in agricultural uses with some rural residential. There are two residential structures north of the property and one immediately west and adjacent to the property. Traffic generation and access will be discussed further in this application. The site design includes water quality feature(s) such as drainage swales and a retention pond to be used to control surface water in the event of a storm. Refer to the Drainage Report and Plan included with application materials. The site design includes secondary containment to adhere to Comprehensive Plan OG.Goal3 listed above. 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. The application materials have been prepared according to the Weld County pre-application meeting held on February 12, 20152 a second meeting held on May 14, 2015, and in conformance with Division 4 starting with Section 23-2-200 of the Weld County Code. The property is zoned "A" Agricultural and according to the Weld County Code, oil and gas support and service facilities are a Use allowed by Special Review in the Agricultural Zone District. Crude oil processing facilities are considered an oil and gas support facility supporting the submittal of this application for review. The Grand Mesa Pipeline is the 20" pipeline that will exit the site and transport crude oil to Cushing, Oklahoma. Additional gathering lines will enter the site including a 12" line that will enter the site from the future Riverside Station. The applicant will submit a separate USR application for this facility in mid-2015 and it is the intent to connect the facilities with the proposed 12" pipeline rather than rely on trucking to distribute the crude oil to the Lucerne facility. As applicable, the pipelines are designed to the Federal Department of Transportation standards and regulated by Federal Energy Regulatory Commission. As such and according to the current Weld County Code, these pipelines are exempt from requiring a separate application for a Use by Special Review permit. 4. What type of uses surround the site (explain how the proposed use is consistent and compatible with surrounding land uses). The surrounding properties are in agricultural production with rural residential uses. The property is within the Airport Overlay District. The applicants have been in contact with the Greeley-Weld County Airport Authority. The nearest residential structure is adjacent to and north of the proposed facility. The applicants held an Open House on May 27 and invited those within '/2 mile of the facility to the Open House. Five individuals representing 3 of the 24 properties within this radius attended. Of those that attended, no negative comments or concerns over the proposed facility were made. S. Describe, in detail, the following: a. Number of people who will use the site. b. Number of employees proposed to be employed at this site. It is anticipated that there will be up to 8 employees associated with the facility. These employees will be available during operating hours and on an on-call basis. Tetra Tech c. Hours of operation. Generally the site will be open from 7 am — 6 pm for trucking operations; however, the site will operate 24/7, 365 days per year. Initially, staff will work 8-hour shifts with some overtime for weekend or as needed work. The Edmond control center operates 24/7 allowing continuous monitoring of the facility and pipeline for increased public safety, protection of the crude resource, and efficiency of delivery. d. Type and Number of structures to be erected (built) on this site. The following improvements/structures proposed to be located on site are listed below. It is important to note that the final dimensions and location of the equipment and structures will be determined with the final facility design and illustrated on building permits. The applicant has provided the best estimation of location and sizes of the equipment and structures for the USR application submittal. The general descriptions of these items are described below: ❑ Eight 150,000 barrel tanks are illustrated on the USR Map, four of which are planned with phase 1 . These tanks have been designed with primary and secondary containment structures. Until the on-site construction for the larger tanks can occur, the applicant proposes utilizing pre-fabricated tanks of smaller sizes but not to exceed the volumes proposed. ❑ Covered truck unloading bays and staging area: 16 covered units are planned, of which 12 are planned with phase 1 . There will be a culvert structure under the bay to collect all crude should an accidental spill occur. Staging of at least two additional trucks can occur per bay. At the south end of the bay area, there will be a hatch to access and remove any collected material. The function of this area is to transfer material from the trucks to the Delivery Manifold. o Driver's Shacks will be included at each lane for drivers to complete their Manifest documents. o Portable toilets will be located at the south end of the bay area. o Instrumentation at the bay will identify the water and sediment content of the material. This facility will accept only merchantable crude oil. ❑ Future Meters: The meters located west of the bay area will have the ability to meter oil entering the facility through gathering pipelines. The facility has been designed to eventually remove trucks from the County Roads by feeding the facility via gathering lines. • Delivery Manifold: All crude entering the system will be routed to the Manifold. It is at this location that the destination of the material (which tank) is made. ❑ Facility Sump: The drain lines for equipment will be collected at this location. This is a collection point for all oil at the facility. Booster Pump: This is the power source for the facility and will pressurize the crude oil from the tank entering the mainline pumps. ❑ Suction Manifold: These are the tank lines that feed the Booster Pumps and assist the crude's transport from each tank into the booster pump. ❑ Firewater Tank and Pump House: A water tank and pump house are illustrated on the USR application map. The applicant and the Eaton Fire Protection District are collaborating on the best method of fire suppressant at the facility which may include potable, non-potable, or dry chemical application. Therefore, the final placement of firewater tank(s) or a pump house should be considered tentative as the need for such, or the placement of such, may change upon site construction. ❑ QA/QC/Sample Building: Testing is completed within this building. The purpose of the building and activity within it is to monitor the quality and sample the products entering the facility. As this facility is for specification oil only, quality control is of upmost importance. Sampling is sent to different labs and this building will provide the correct instrumentation to perform the work. This building may be a manufactured structure permanent to the site. By Tetra Tech including this in the USR application, the need for a Zoning Permit for Mobile Structure is negated. ❑ Warehouse: The warehouse will house spare equipment such as a snow tractor or bobcat and equipment needed to maintain the site. This building may be a manufactured structure permanent to the site. By including this in the USR application, the need for a Zoning Permit for Mobile Structure is negated. ❑ Power Control Room (PCR): The switch gear and electrical equipment will be housed at this location. This building may be a manufactured structure permanent to the site. By including this in the USR application, the need for a Zoning Permit for Mobile Structure is negated. One will be constructed with phase 1 and the second may be needed for phase 2. ❑ Surveillance Meters: Crude flow will be metered in this area for line balancing purposes. ❑ Mainline Pumps: This station will enable proper flow into the Grand Mesa Pipeline. ❑ Pipeline Surge Relief: This is a pressure over-protection system for the 12" pipeline entering the facility as well as the 20" pipeline exiting the facility. ❑ Launchers and Receivers: These pumps will pump the crude oil from the 150,000 barrel tanks into the Grand Mesa Pipeline to Cushing, Oklahoma. Equipment called "Pigs" are used to check and clean out the lines. The area labeled "Launcher" is the launching area for when the pigs are needed. ❑ On-site transformers: This is the location where power will enter the site and be distributed for on-site activities only. The footprint illustrated on the application maps describes the anticipated footprint. This is the general location of the facility. Once the applicant and Xcel have finalized the location and equipment needed to supply power to the facility, any appropriate changes will be noted and communicated with the County. ❑ Office: Technicians, Operations Staff and the Area Supervisor will office at this location during the day. For safety and security, a SCADA system. in Edmond, Oklahoma will be used to monitor this facility 24/7. This building may be a manufactured structure permanent to the site. By including this in the USR application, the need for a Zoning Permit for Mobile Structure is negated. ❑ Construction Office(s): There will be several mobile units installed in the area illustrated on the submitted USR Map. For the purpose of this application, we've illustrated an area to be used for construction offices. It is important to note that this proposed location may change once contractors are selected. These units should be considered permanent as the use may extend beyond 18 months. By including this in the USR application, the need for a Zoning Permit for Mobile Structure is negated. ❑ Construction Lay-Down Yard: This area will be used to store pipe and other equipment needed for the construction of the Grand Mesa Pipeline, the future facility to the west as well as this proposed facility. ❑ DRA and CI Skids: Drag Reducing Agent and Corrosion Inhibitor will delivered and injected into the pipeline here. A future sign for the facility will not exceed 16 square feet in size and will not be greater than 6' tall. A typical sign detail is included on the. USR Map submitted with this application. It will be placed at the main truck entrance off of Weld County Road 66 on either the east or west side of the entrance. A small sign will be installed on the fence near the entrance from Weld County Road 45 to be used to direct traffic to the main entrance or to dictate what type of traffic will be accepted from the WCR 45 access (construction equipment, etc.). The traffic routes will be surfaced with asphalt or road base/graveled as illustrated on the USR map. Aggregate materials such as pea gravel or larger gravel will cover portions of the site around the Tetra Tech equipment areas similar to other facilities to reduce dust and weeds and to allow easy maintenance around the facility. e. Type and number of animals, if any, to be on this site. Animals are not going to be kept on site. f. Kind of vehicles (type, size, weight) that will access this site and how often. It is anticipated this site will generate up to 260 vehicles per day with the majority of the trips occurring during daylight hours. Of these trips, 250 will be trucks, 8 employees and up to 2 miscellaneous trips. Offloading trucks are third party trucks. The main access to the site will be from Weld County Road 66, approximately 1 , 170 feet from the intersection of Weld County Roads 66 and 45. The second access from Weld County Road 66 is located approximately 500 feet from the intersection of Weld County Roads 66 and 45. The easternmost access is one-way for truck entrance. The westernmost access is one-way for truck exiting. The access from WCR 45 is for employee vehicles and is a two way access. An emergency access was requested by the Eaton Fire Protection District and i.s located along Weld County Road 45 approximately 1 ,490 feet from the intersection of Weld County Roads 60 and 45 on land owned by Blue Grama. A tracking pad at the WCR 45 access is proposed to keep trucks from tracking onto the County Roads. An access permit is submitted with this application. Site design was also discussed with the Eaton Fire Protection District prior to submittal and the results are illustrated on the plans submitted with this application. About 1-4 times per month, Blue Grama could have deliveries of DRA (drag reducing agent) and CI (Corrosion Inhibitor) for the pipeline. This material will be delivered via semi-trailer. Other maintenance activities will be accomplished with standard passenger trucks. A crane may be on-site during construction activities. The facility has been designed to receive crude via pipeline as well as truck. The initial site design has been designed to receive up to 2/3 of the product via truck and 1/3 of the product via pipeline. According to the Traffic Impact Study prepared by Gene Coppola, "since the number of turning vehicles will be well below County warrants indicating the need for turn lane improvements, it was determined that turn lanes will not be needed at any intersection with this development (page 16)." Furthermore, "Based on the above documented investigations and analyses, the following can be concluded: ❑ Current operating conditions are acceptable in the area of the Blue Grama site. ❑ No auxiliary lane improvements are needed at the site access points or at critical intersections. This determination was made using Weld County auxiliary lane warrants. ❑ Site trips can be readily accommodated by the existing street system. ❑ Future intersection levels of service will, in fact, essentially replicate current levels of service. Accordingly, no noticeable impacts are expected. ❑ Blue Grama is viable from a traffic engineering perspective. In summary, acceptable operating conditions are expected in the area of the Blue Grama Lucerne Facility for the foreseeable future." There will be a setback from Weld County Road 66 to allow trucks to access the site through the gate and have space to stage off of the County Roads. Separate accesses and on-site circulation routes will accommodate the goal of keeping passenger and truck traffic separated. Tetra Tech g. Who will provide fire protection to the site. The property is within the Eaton Fire Protection District boundary. Several meetings have been held with the District. The applicant has incorporated the District's suggestions into the design of the facility. Future collaboration between Blue Grama and the District is anticipated. h. Water source on the property (both domestic and irrigation). An "Intent to Serve" letter from North Weld County Water District is included with application materials. A tap from the District will be provided for the potable uses. A well may be utilized for non-potable uses including fire suppression. As the use of a well is not clearly necessary at this time, the Water Supply Summary Statement has not been included with application materials. Additional water needs on-site include water needed for hydrostatic testing of the tanks. Available water in the vicinity will be tested for corrosive bacteria and other negative factors prior to contracting for the water provision. An on-site water tank could be used to supply water should an on-site foam/dry chemical fire suppression system be developed. On an annual basis, it can be assumed that the water in the tank will be topped off to maintain a full condition in the tank in the event of use. Due to the variable nature of the use, it is difficult to quantify the expected annual use. i. Sewage disposal system on the property (existing and proposed). Sewage disposal will be through a new septic system. The existing structures on-site are served by an individual septic systems which will be property abandoned during site construction. Portable toilets and hand-washing facilities will be provided during construction and for truck drivers coming to the site. Portable toilets will be placed near the unloading bays for truck drivers. j. If storage or warehousing is proposed, what type of items will be stored. A construction lay-down yard is proposed for the southeast portion of the property. This yard will contain new pipe and facility-related equipment. 6. Explain the proposed landscaping for the site. The landscaping shall be separately submitted as a landscape plan map as part of the application submittal. Landscaping is not proposed for the facility. Vegetation can be a fire hazard at these types of facilities. The water quality features will be re-seeded for erosion control. The undisturbed areas will remain native. The remainder of the site, including the process areas, will be covered in road base, rock or other non-flammable aggregate material. These materials are most conducive to keep the site weed free. Topsoil that will be stripped during construction will be stockpiled and seeded or covered to prevent blowing dust. Following construction, the topsoil will be redistributed on-site in areas where it is not a safety hazard to have vegetation growing; any bare soil will be re-seeded to prevent erosion. 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 the detention ponds. The one- hundred year developed storm event will be released at the ten-year historic rate from the ponds. Additional details Tetra Tech can be found in the Drainage Report attached with the USR application submittal . Blue Grama will most likely request an early release of the Grading Permit. 9. Explain how long it will take to construct this site and when construction and landscaping is scheduled to begin. Blue Grama anticipates that it will take approximately 6 — 12 months to construct the site and are aiming to have the site functioning by late summer, 2016. 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. In addition to the response to Question 5d above, the following additional on-site improvements will be constructed at this location: ❑ Over-lot grading will be completed in late Summer, early Fall, 2015 and continuing into the Winter, 2015. ❑ Detention and drainage will be constructed after over-lot grading through Winter, 2015. O During construction, water will be used for dust suppressant as needed. O Blue Grama is proposing temporary and permanent manufactured structures as illustrated on the USR Map submitted with application materials. A temporary construction trailer may be needed at a temporary site until grading can be completed. Tetra Tech Blue Grama Land Corporation Lucerne Station USR Waste Management Plan 1 . All waste on site will either be taken to Waste Management or Waste Management Conservation Services Inc. (CSI). Waste Management will take care of typical waste generated onsite. It is anticipated that the site will generate no more than one trash dumpster of trash within a week. CSI will take care of any solids/sediments accumulated in the tanks. The solids/sediments are removed with a vacuum truck and then hauled to CSI with a Waste Management manifest. The solids/sediments are stored in the tanks until removal. The amount of solids/sediments that will be generated is unknown at this time, but that information will be provided to the Weld County Department of Public Health and Environment when it is available. Addresses and phone numbers for Waste Management and Waste Management Conservation Services Inc. are provided below. Waste Management North Weld Landfill 4000 WCR 25 Ault Co, 80610 866-482-6319 Waste Management - Conservation Services Inc. (CSI) 41800 E 88th Avenue Bennett, CO 80102 303-644-4395 2. Sewage from portable restrooms will be taken off-site for disposal at: McDonald Farms Enterprises, Inc. 7247 East County Line Road Longmont, CO 80501 303-772-4577 3. Various chemicals will be used with the operation. An MSDS, as required, will be available on site for each chemical during operations. 4. The applicants operations will be in accordance with the approved Waste Handling Plan. The operator of the facility will notify the Weld County Department of Public Health and Environment in writing, in the event the plan is amended. The amended plan will be reviewed and approved by the Weld County Department of Public Health and Environment. 5. All development standards will be adhered to. Blue Grama Land Corporation Lucerne Station USR Dust Mitigation Plan During the construction phase of the facility, water trucks will be utilized to suppress dust. The Storm Water Management Plan will be followed to mitigate soil erosion during the construction phase of the project. After construction, the main traffic route will be paved. Secondary traffic routes and disturbed areas will be stabilized with road base, recycled base or other aggregate materials. The internal speed limit will be less than 10 mph. Should fugitive dust be generated on site, the applicants will abate with water or chemical treatment. A Weld County grading permit will be applied for during the construction phase of the project if more than one acre of land is disturbed. In addition, a construction stormwater permit is required through the State of Colorado if more than one acres of land is disturbed. This will be acquired, if necessary, prior to the construction phase of the project. C (.5114 Weld County Public Works Dept. 1111 H Street ACCESS PERMIT co P.O.

INTRODUCTION This study addresses the traffic engineering impacts of the Blue Grama Lucerne Facility in Weld County Colorado. It assesses site operations in both the short and long term time frames. Primary activities will focus on collecting crude oil products for pipeline transport to Cushing , Oklahoma . Blue Grama will be located on the south side of CR 66, just west of CR 45 . This site will primarily serve the Greeley — Windsor area and other areas generally located to the west and south of the facility. A vicinity map is presented in Figure 1 . Key work tasks undertaken as part of this effort are described below. • Obtain current traffic and roadway data in the immediate area of the site . • Determine site generated traffic and distribute this traffic to the nearby street system . • Estimate traffic for future short- and long-term conditions. • Evaluate traffic operations with the proposed facilities fully operational un- der future conditions. • Identify areas of potential deficiencies. • Recommend measures to mitigate the impact of site generated traffic and other deficiencies as appropriate.

Current Road Network SH 392 is located one mile north of the site and is the major east — west roadway extending from U .S. 85 east. It has one lane in each direction and there are currently no existing turn lanes at the SH 392 intersections with CR 43 , CR 45 and CR 47. The posted speed limit is 65 miles per hour. U . S. 85 is the regional truck route serving this area and generally extends in the north — south direction . It has a 65 MPH speed limit, two lanes in each direction and all auxiliary lanes at all intersections . CR 66 , CR 43, and CR 47 are all two lane paved roadway. CR 45 is paved south of CR 66 but gravel north of CR 66. There are no posted speed limits on these roadways. U . S. 85 and SH 392 are under CDOT control with other roadways under Weld County control . Current roadway geometry is shown on Figure 2. B). Current Traffic Conditions Peak hour traffic counts were undertaken at a number of intersections in conjunction with this study including the CR 66 — CR 43, CR 66 — CR 45 and CR 66 — CR 47 intersections. These intersections are considered critical given the anticipated site traffic routes and site traffic activity. The high continuous peak hour within the two hour count times represents the morning and afternoon peak hour. Peak hour traffic at key intersections is shown on Figure 3 with count tabulations for all count locations provided in Appendix A. On a daily basis, some 219 vehicles per day use CR 66 , west of CR 45 adjacent to the site based on County data . Capacity analyses were conducted at the key intersections using current traffic de- mands and the existing roadway geometry. Current operating levels of service are shown below. 3 U ce 2 O W cV Q L Q .Li. ° V"Ir el z re le s Aj\t• 41> Sf 110 <p.

As shown above, very acceptable operations are currently being experi- enced in the area of the Blue Grama site. Capacity worksheets are provided in Appendix B. C). Surrounding Land Uses The site is currently used for industrial and agricultural purposes and is surrounded by other agricultural and industrial land uses. Several other oil and gas facilities currently exist or are being built in the general area. 6 III . SITE ASSUMPTIONS Blue Grama will be located in the southwest corner of CR 66 and CR 45 . It will be an origination station of the Blue Grama pipeline which will gather crude products for pipeline transportation to Cushing, Oklahoma. Product will arrive on site by both pipeline and truck, initially in about equal portions. As additional pipelines are con- structed , truck service to this site will be reduced . Twelve unloading bays will be constructed with the potential for 16 at build out. A lay down yard will also be built. Blue Grama is expected to be in service in 2016 and will operate 24 hours per day, 365 days per year. A concept plan for the site is provided on Figure 4. An estimated 250 trucks will use this site in a 24 hour period with 75% of the activity expected during daylight hours and the remaining 25% expected at night. On bal- ance, 13 — 14 truck round trips are anticipated each hour. Traffic activity associated with the lay down yard will be minimal. Some 14 employees will visit this site daily, 4 of which will be permanently working on-site with shifts ranging from 8 — 12 hours. About one-third of the employee visits are expected at night. During daylight hours, four inbound employee trips are ex- pected in the morning with four outbound employee trips expected in the afternoon . To be conservative these trips were assumed to occur in the same hour. On a daily basis, 264 round trips are expected from the Blue Grama site . Of these, 250 round trips will be trucks; however, the number of truck trips will be reduced as pipeline usage increases . Site access will be provided by two driveways to CR 66 with the east driveway being an entrance and the west driveway being an exit. Additionally, the lay down yard will have a driveway to CR 45 . 7 t _ _ _ N - - - - _ _ \ - - - - - - - - - - - - - - CR66 —x x x� ` r-X-X-7.--x- e x x x x x___ - - - I 'N vr LL x - -1 o X13 IL x�J.".. ./4 - le," I in I \\\:-.C o ICC DC al linin ri err II x X O �a� I 02=0:2=0 x 040 Olg== X ._.

With this service area, virtually all site traffic will arrive at and depart the site from or to the south , southeast, west, southwest, and northwest. Other geographical areas will be served by other facilities generally located or planned to the east and northeast of Blue Grama. Site traffic was assigned to the various roadways based on the Blue Grama service area, the existing and planned roadway network, and the serviceability and efficiency of the various routes. Principal area roadways expected to serve site traffic are CR 66 from CR 47 to US 85 , CR 47 south of CR 66, CR 43 north and south of CR 66, SH 392 west of CR 43 , and US 85. This resulted in the site traffic distributions shown on Figure 5 and the peak hour site traffic shown on Figure 6 . Since all site traffic will use at least one of the CR 66 intersections with CR 43, CR 45 , and CR 47 , these intersec- tions were selected for further evaluation in addition to the site access points. Site traffic at other locations is not considered meaningful. IV. FUTURE CONDITIONS A). Background Traffic Future background traffic was estimated using a straight-line growth rate of 5% annually for County Roads. Background peak hour traffic is shown on Figures 7 and 8 for the short term (2016) and long term (2035) time frames , respectively. B). Total Traffic Total traffic volumes were developed for each future evaluation year, namely 2016 and 2035. Total traffic is the combination of site and background traffic. This infor- mation is shown on Figure 9 for the short term and on Figure 10 for the long term . 9 1 C r M Z Z tom) to 2 L t u. p To 0) C U. i• O Z I- Lu T ~ en %0Z Lf213 IeuiWON jeu!woN c d 0 9fr ?J3 w A 0 co CV NO MP'IeuiwoN %5 %9Z • A to 0 V V 4 %0£ 98 •S•n %o � 10 M CO to U = U m LL co L g U) z N / N �- (00 + 1£) £ / (00 + 1E) E LP NO R ♦ 906 NUN ---► (O6 + 10) 6 / O6 + 10) 6 m I t r az & + z + U o M r r cn + to ~ o U 4, r r 0 d. + + 4— l— a 0 r r M + H (t) j— N / N j— N / N 5t' e13 N / N —� (sir U z zz + z zz M 7+ m (11 eL + C] f'^ M `a aauei;u3 a;!S U a H r U M to L k— tot, +1s)* too + le) £ ° (017 + 14) 9W00 + 1101. 1 _ 0 d 74 N Y ;IXaa;IS g >. zU2 U N 0 2 Q II II N Q z + + + U I- d N y Cs) W of W C9 ^0 0^^ W 0 + + + N 0 cei N0col I. + 1Z) E 1 (00 + 1Z) Z 4) i 4 (00 tic) E / (a" + 1E) P 09 I Et' a3 OE N / N (a0 + it) Z / (a6 + lZ) £ -_, t U p O + + N to N CD U 0 U r r N + N +iNt 1 1 r ( � 1 CC ri U N O zzz ZZZ z D Ai liss ti ce N/N-,1 N/N 2 D OZ/0 6 4-0Z/9Z 3 9/9-1/2 0-9101 U R t I l LL cz n 2 to 1- cc ....� 11.1's.\ H `\SIP Lti NO o I \ NJ t taiga la.

Shod- and long-term conditions were evaluated . A). Short Term Turn lane improvements were investigated for the Blue Grama site. This involved com- paring traffic at the site access points and key intersections with the County's numerical turn lane warrants. County turn lane warrants are as follows for higher speed roadways. • More than 10 peak hour vehicles turning left into the facility warrants a left turn deceleration lane • More than 25 peak hour vehicles turning right into the facility warrants a right turn deceleration lane • More than 50 peak hour vehicles turning right out of the facility warrants a right turn acceleration lane Since the number of turning vehicles will be well below County warrants indicating the need for the turn lane improvements, it was determined that turn lanes will not be needed at any intersection with this development. Consequently, the resultant short term roadway geometry is shown on Figure 11 . 16 • co r rt } 1 a U w W >- r Q T 2 o = 4 E 12 A `its w cc . el a 1t )43 ct _ N f <tool ittAr AlNiti. i> nit Oa_ CvaPs 9V NO + v_i%\k/Ar - D V E tVa .?

Capacity worksheets are presented in Appendix C. B). Long Term A review of long term peak hour traffic also determined that turn lanes will not be warranted in the long term with Blue Grama . Accordingly, the short term roadway geometry shown on Figure 11 was retained through the long term to determine oper- ating conditions in 2035. Resultant operating levels of service are shown below. 18 , LONG TERM OPERATING CONDITIONS WITH BLUE GRAMA Movement/ Level of Service Intersection Control Direction AM PM CR 66 — CR 43 Stop EB LTR A A (E - W) WB LTR A A NB LTR B B SB LTR B B CR 66 -- Site Exit Stop NB LR A A CR 66 — Site Entrance N/A WB LT A A CR 66 — CR 45 Stop EB LTR A A (E — W) WB LTR A A NB LTR A A SB LTR A A CR 66 - CR 47 Stop EB A A (All) WB A A NB A A SB A A Overall A A As indicated above, the site access intersection will operate acceptably in the long- term. Capacity worksheets are available in Appendix D. VI . CONCLUSIONS Based upon the above documented investigations and analyses, the following can be concluded . • Current operating conditions are acceptable in the area of the Blue Grama site. 19 • At full operation , Blue Grama will generate 32 morning and afternoon peak hour trips. On a daily basis, up to 264 round trips are expected of which , 250 will be trucks. The number of site trips will be reduces as new pipe- lines become available to serve this site. • No auxiliary lane improvements are needed at the site access points or at critical intersections. This determination was made using Weld County auxiliary lane warrants. • Site trips can be readily accommodated by the existing street system . • Acceptable levels of service are expected for all traffic movements at all intersections. These levels of service will be maintained from opening day through the long-term. • Future intersection levels of service will, in fact, essentially replicate current levels of service. Accordingly, no noticeable impacts are expected . • Blue Grama is viable from a traffic engineering perspective. In summary, acceptable operating conditions are expected in the area of the Blue Grama Lucerne Facility for the foreseeable future. 20 APPENDIX A � N t�o U M � LL = U ¢ y � r 00o Z �IooI � 0/0-�r � y�-0/0 J 6UOl� �-- lZ/9Z U E/9� } �l/E � I � mov QON \` � '�., cv a� , , ; N � m � ` � Z/b1 � LOl/8 6/8� �4/OL Zl/L-� ♦ j- lZ/b � I � o rn�n � Nn n � n e � nn \ N�O � ut�'� 1 �'�zie zi�--. .--ai� 0/E� } j-Z/S � I � N O� M � vn �\ � '�, sv a� . ; s[� : m ; P 1 1 1 O� �- W oio�''� �1 �''�oiz ~ an� � uo � oiz-a s- u� � T � � « � � a � � , M � o � m N n sv a� ; ,, , , .� � ; b � ` � Q oJ = �N � mmp N zn�'� 1 �'�-a�s� u�-r`� 1 �'�sro a bblLL—� .--aus sysz---. �-9E/LL � � Zl/4 � � ^j-El/Z E/E�� r4/6 � p I NNN mm � p a ��n vmo W a � J a�e � � t0 p '�V� M L7 RO �f �.: i0 M � � CO W OJ M �N�.

Rainfall data from NOAA Atlas 14 Volume 8 for Colorado was usetl in conjunction with Urban Drainage design documents for ihis tlrainage report. 2.) Detention pond designs shall be sized to store the stormwater mnoff generated by the 100-year, 1 hour storm from the developed site antl to release the stormwater at a rete not to exceed the historic 5-year, 1 hour storm. Detention pond embankments should be a 4:1 (H:� slope or flatler to facilitate maintenance. Detention pond bottoms should have a minimum slope of 1 %. -Due to anticipated revisions to ihe Weld County Cotle, detention ponds were sized to store runoR from the 100-year, t hour storm from the developed site and release at a rate that tloes not exceed tne 10-year histeric rate. 3.) Channel lining criteria is specifed for various types of channel lining in Table 5-9 of the Weld County Engineering and Construction Criteria. -Turf Reinfo�cement Mat is recommended to reduce erosion due to the velocities of flows and slopes of the channels on site, no vegetation on site due to fre hazard, and onsite non-cohesive soils. 4.)

Proposed development encompasses appiroximately 73 acres +/- for a Truck Unloading and Oil and Gas Support Facility, as defined in the Weld Counry Code. The proposed facility will be the origination location for the Grand Mesa Pipeline. Blue Grama has commitments from key industry producers to transport crude oil from Weld County to Cushing, Oklahoma. From Cushing, the resource will be piped for refiuement before being sent to other domestic and international destinations. Final development of this site to meet the intended function will int��oduce an increase in impervious cover from facility development resulting in an increase in peak stonnwater runoff. This report exainines the following: Undeveloped flow patterns of offsite and on-site drainage basi��s. Proposed on-site drainage basins. � Stormwater facilities designed to mitigate dowustream impacts associated with increased storn�water runoff. The coutents of this report are prepared, at a ininimum, in accordauce with the Weld County Code for a Final Drainage Report. 2. 0 GENERAL LOCATION AND DESCRIPTION 2. 1 Locarion and Existin.2 Conditions The proposed Lucerne Station is located on a 73 acre +/- parcel south of and adjacent to Weld Cowiry Road (WCR) 66 and WCR 45 . More specifically, the site is located in part of the east half of the northeast quarters of Section 27, Township 6 North, Range 65 West of the 6`h Principal Meridian, in Weld County. A viciniry map is provided in Appendix A-1. The site will be owned by Bluc Grama Land Corporation . The property is currently used for agriculture. There are also a few rural residential properties in the vicinity of the proposed siYe. Drxinage at the proposed development area currendy sheet-flows to the southeast across the proposed properry to an inigation ditch that flows south along the west side of WCR 45 . The historic drainage plan for the site is attached to this report as Appendix A-2 . 2.2 Provosed Development Proposed developmeut iucludes the coustruction of a Truck Unloadiug aud Oil aud Gas Support Facility as defined in the Weld County Code. Anticipated site features are highlighted below and can be found on the USR Map. These features and others contribute to an increase in impermeable surface area, which cause increased runoff from the proposed site when compared to prc-developed conditions. _ Storage Tauks: Eight storage tanks comprising 150,000 barrels each are ultimately proposed for the site. Pour of these tanks will be constructed for the Phase 1 portion of the development. Future development (Phase 2) will construct the remaining four storage Final Drainage Report I June 2015 Q�UO GT81n8 LuCerne StAholt Y:AI24G03VI33-1 24 603-1 500SuocxUieporcs�Dreinu¢e Re�urc\Finul Druinage Itepoh_Luceme.Aocx tanks. A benn will be developed around tanks to restrict free runoff form tauk containment locations. Unloading Bays / Staging Area: Ultimately, sixteen covered bays are proposed. For Phase 1 , twelve bays will be constructed. Trucks euteriug the site will pull iuto this area and unload their payload. Asphalt will be incorporated into this area for trucks to drive on. Equipment areas and buildings will be positioned on the site. During construction, several mobile units will be placed on-site to accouimodate constmction activities and personnel. Internal roads will provide access to these facilities. Typically, roads outside of the unloading bays will be consTructed of gravel or a crushed base type material. 3. 0 DRAINAGE BASINS AND SUBBASINS 3. 1 Maior Basin Descrznxion The Lucerne Station is located in rural Weld Counry and is surrow�ded by agricultural land along with some residenYial housing surrounding the site. The project siYe is within a F�MA designated area, Zone C : "areas of nunimal flooding." The site is located in Flood lnsurance Rate Map (FIRM), Cominm�iry Panel No. 080266 0627C, attached to this report as Appendix B-1 . Zone C refers to an area that may exhibit ponding and other localized drainage proble�ns during storm events. In terms of the area in the vicinity of the proposed Luceme Station, relatively flat terraiu will allow ponding to occur where overland slopes are mild. Zone C locations do not merit a detailed flood study or designation as a base floodplain. According to the Soil Survey of Weld County, Cola�ado, Southern Part, site soils are primarily composed of sandy loams and fine sandy loams. Specifically, soils for the project site are identified as Oluey Fine Sandy Loa�n (46), Otero Sandy Loam (50 & 51 ), and Vona Saudy Loam (75). Corresponding soil types within the project site are predominantly Hydrologic Soil Groups A and B . Soils in Group A are comprised of sand, loamy sand or sandy loam. Group A soils have low runoff potential and high infiltration rates whcn thoroughly wet. Group B soils consist of silt loam or loam and experience moderate intiltration rates. On-site soils are anticipated to have less runoff potential and greater capacity for infiltration. A detailed soil survey report is provided in Appendix B-2. 3.2 Hisfioric Draina�e Patterns The project site is locxted within two historic draiiiage basins, designated as Historic Basin A and Historic Basin B. Historic Basin A is located uorth aud west of the proposed project site. Ruuoff fro�n this basin flows southeast toward the proposed project site and ultiinately to an irrigation ditch aloug WCR 45 . Current land use within this basin is agricultural farn�land xnd has gentle slopes. Historic Basin B is located west and north of the site and is also curreudy uscd as agricultural fannland. Runoff from this basin generally flows to the south along the west side of the proposed project site. Historic runoff coe�cients are calculated for each soil rype using the methods detailed in the Urban Storm Drainage Criteria Manua(, Volume 1, Ch. 5. Because historic drainage basins are less than 160 acres, the Rational Method was used to analyze historic peak flows.

Offsite Basin O- 1 is located north of the site and in general drains to the southeast towarcl WCR 45 . Flow is ultin�aTely captured by an irrigation diYch that runs along the western side of WCR-45 (See Section 3, Drainage Channe] Siziug). Runoff from this basin will be routed around the site through au offsite drainage channel . Near the southern portion of the project site, O- 1 ' s channel geometry will transition to unconfined sheet flow via a riprap section. ilow will migrate to offsite conveydnce where it has historically found conveyance. Basin O-2 is located west of the site and in general drains to the south. Runoff from this basin will be routed around the site through an offsite drainage channel . Peak flows for the ] 0-year aud 100-year storm eveuts for the offsite drainage basins are summarized in Table 2, below. Detailed runotf calculations for the offsite drainage basins can be found in Appendix B-5.

Based on this criteria, a 100-year storm is used as the majar sTorm when evaluating existing and proposed drainage faciliTies. Final Drainage Report 3 June 2015 Q�UO GT81n8 LuCerne StAholt Y:AI24G03VI33-1 24 603-1 500SuocxUieporcs�Dreinu¢e Re�urc\Finul Druinage Itepoh_Luceme.Aocx R�noff Calculations: Because all drainage basins cvaluated in this analysis are less than 160 acres in area, the Rational Method was used for stormwater runoff calculations. The time of concentration for each basin was es�imated using the methods detailed within the Urban Storm D�-ainage Criteria Manual, Uolume 1, Ch. 5. Rainfall Data: Site rainfall depth information was obtained from the National Oceanic and Atmospheric Administration (NOAA) Atlas 14, �o/ume 8, �ersiora 3, Precipitation-Freyuencv Atlas of the United States (2013). This data supersedes the default rainfall depth information provided in the Urban Storin Drainage Crite�za Manual. C�n�ent NOAA data was used for the deterniination of point rainfall data. NOAA data formed the basis of the intensiry-duration-frequency (IDF) calculations for other storm frequencies and duratious using Urban Drainage methods. Rainfall data is presented in Appendix B-3. Pipe and Culvert Sizing: Site storm infrastructure capacities have been evaluated using Manniug's Equation. On-site culverts are sized to convey the 100-year stomi event. Additionally, outlet pipes from each detention pond are sized for a specitic release rate of the 10-year historic tlow with the use of an orifice plate. �rosion control devices will be provided at all culvert and swale ouflets to protect against downstream erosion. Culvert sizes were detenniued using Bent]ey CulvertMaster version 33 and Bentley StormCAD V8i software. Pipe sizing calculations are provided in Appendix C-1 . Drainage Channel Sizing: The majariry ofon-site drainage conveyancewill occurwithin minor ditch alibminents that are strategically place throughout the proposed site. Ditch conveyance will ultimately transport flows to one of two on-site detention ponds. In son�e locations, minor swales are placed to help direct flows in areas where additional contour detail is needed to ensure flows are transported to desired locations. Swales help to facilitate conveyance of minor flows. 'I�vo offsite drainage channels are proposed that will route otfsite flows from Basins O- I and O-2 around the proposed site. The Basin O- 1 channel begins near the northwest corner ofthe proposed site and traverses the north side of the proposed development, paralleliug WCR 66 along the south side of the road. Upon reaching the intersection of the proposed subdivision exemption (SUBX I 5-0019), the channel transitions to a southern direction and then an easterly direction as it parallels the western and southeni properry boundary of the proposed subdivision exemption (SUBX15-0019). Finally the channel transitions to a southern direction for the remainder of the project site. Near the southern portion of the site, the ditch transitions from channelized flow to ovei9aud, un-concentrated t7ow as it reestablishes its historic flow pattern, evenhzally reachiug the confluence of the irrigation ditch. Another offsite drainage channel is proposed along the west side of the site to coirvey flows to the south that originate from Basin O-2 . All channels have been sized for the I 00-year storm event using Manning's Equation. DeYailed channel calculations have been provided in Appendix C-2. Riprap will be placed at all culvert outfalls, and has been sized according to the Urban Drainage Flood Conh ol Disb-ict Manual, Volume 2. Detailed riprap calculations have been provided in Appendix C- 3 .

Detention Pond B will detain the 100-year developed storm event from DeveJoped Drainage Basins 2A, 2B, and 2C . Both detention ponds will be configured to release no n�ore than the ] 0-year hisToric flow at the points of analysis in accordance with Weld County criteria. A miuimum of one foot of freeboard will be provided for each detention pond. The required water quality capture volume will be contained within the detention volume for each detention pond . Emergency spillways, in the forni of a trapezoidal weir, are proposed to convey the 100-year flow rate at a 6-inch depth. Detailed detention pond calculations are provided in Appendix G4. Water Quality Pond Sizing: Water quality ponds are required prior to releasing storniwater ruuoff from the development. Detention ponds will include a water quality orifice plate on the outlet siruchire in accordance with the Urban Storm Drainage Criteria Manual. The volume added to the detenYion ponds to account for water quality was detenniued following UDFCD's Detention Design — UD- Detention v3.34 spreadsheet. Detailed water qualiry pond sizing iuforn�ation is presented in Appendix G5. 5. 0 DRAINAGEFACILITYDESIGN 5. 1 General Concept Drainage ditches and culverts for the proposed site are designed to couvey runoff from the ] 00-year storn� event in the developed condition. Oirsite drainage features will convey stonnwater flows through the site to two proposed detention ponds, designated as Detention Pond A aud Detention Pond B, respectively. Detention Pond A is located in the southeast portion of the site. Detention Pond B is located in the northern part of the site on the west side. In order to adequately size drainage chaunels and culverts, the proposed site was subdivided into smaller drainage basins, which reflects the developed drainage. Detention ponds have been designed to detain the 100-year storni, 1 -hour event iu the developed conditiou and to release at a rate that does not exceed the I 0-year historic rate. Detention Pond A will discharge to Poiut of Analysis (POA) A, which corresponds to the historic drainage poiut of discharge. Detention Pond B will also discharge to POA A, which corresponds to the historic drainage point of discharge. The followiug table shows the allowable discharge for each POA based on the historic 10-year flows and the developed I 0-year flows.

Developcd Basins lA, IB, IC and 1D comprise Basin 1 and runoffwill drain into Detention Pond A. Detention Pond A will discharge in POA A and will not exceed the 10-year histoiic rate. Developed Basins 2A, 2B and 2C will drain into Dete�tion Pond B. Discharge from Dete�tion Pond B will also discharge info POA A and will uot exceed the 10-year historic rate. Drainage Basiu 1 is located in the eastern half of the project site area. Drainage Basin 1 is divided into four sub-basins in order to size the drainage ditches and culverts that it drains. Basin I A will sheet tlow to the southeast into Channel 1 . Chamiel 1 and Culvert I will convey the flow to Detention Pond A. Basin 1B will sheet flow into Detention Pond A. Basin 1C contains the ]ocation of future tanks and secondary containment. Basin 1C will sheet tlow into Detention Pond A until future development occurs. Detention Pond A is designed to hxndle flow fron� Basin 1C before the future development occurs. Upon construction of the future tanks, Basin 1 C will no ]ouger draiu iuto the detention pond. Flow trom this location will be regulated by a gated outlet pipe. Basin 1 D contains a small area north of the secondary conYainnlenT area. Runoff from Qasin 1 D sheets flows into Channel3 and is conveyed through Culverts 3a aud 3b to Detention Pond A. Drainage Basin 2 is located in the norCh a��d central portion of the project site. Drainage Basin 2 is divided into three sub-basins in order to size the draivage ditches and culverts which they drain. Basin 2A will sheet flow to the southeast into Channel 2 . Channel conveyance will flow through Culvert 2 into Detention Pond B. Basin 2B will sheet flow away from the pump out area toward the edge of gravel. A shallow drainage swale will intercept flow and direcf it to the detention pond. Basin 2C will sheet flow into Detention Pond B. The followiug table provides the peak flow rates for the on-site drainage basius. Detailed runoff calculations for the developed condition can be found in Appendix B-6.

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.nres. usda.gov/wps/portal/ nres/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=nres) 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. The U .S. Department of Agriculture (USDA) prohibits discrimination in all its programs and activities on the basis of race, color, national origin, age, disability, and where applicable, sex, marital status, familial status, parental status, religion, sexual orientation, genetic information, political beliefs, reprisal, or because all or a part of an individual's income is derived from any public assistance program. (Not all prohibited bases apply to all programs. ) Persons with disabilities who require alternative means 2 for communication of program information (Braille, large print, audiotape, etc.) should contact USDA's TARGET Center at (202) 720-2600 (voice and TDD).

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 surtace 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. Also presented are various metadata about data used to produce the map, and a description of each soil map unit. 7 3 Custom Soil Resource Report 3 e Soil Map s � � °s °s � � s3oan s3oioo s3ozoo s3o3ao s�oaao s3osoo ssawo s3o�eo w� n� w"ry li i i i: l_� i .

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 forthe properties ofthe 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 10 Custom Soil Resource Report 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 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 misce/laneous 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, Southern Part 39—Nunn loam , 0 to 1 percent slopes Map Unit Setting Nafiona/ map unit symbol: 2t1n3 Elevation: 3,900 to 6,250 feet Mean annual precipitation: 13 to 16 inches Mean annual air temperature: 46 to 54 degrees F Frost-free period: 135 to 160 days Farmland classification: Prime farmland if irrigated Map Unit Composition Nunn and similar soils: 85 percent Minor components: 15 percent Estimates are based on observations, descriptions, and transects of the mapunit.

This standard is based on 24 consecutive opacity readings taken at 15-second intervals for six minutes. The approved reference test method for visible emissions measurement is EPA Method 9 (40 CFR, Part 60, Appendix A (July, 1992 ) in all subsections of Section II . A and B of this regulation. Re ulation 2 — Odor Section I.A - No person, wherever located, shall cause or allow the emission of odorous air contaminants from any single source such as to result in detectable odors which are 002 measured in excess of the following limits: For areas used predominantly for residential or commercial purposes it is a violation if odors are detected after the odorous air has been diluted with seven (7) or more volumes of odor free air. Re ulation 3 - APENs Construction Permits O eratin Permits PSD Part A-APEN Requirements Criteria Pollutants: For criteria pollutants, Air Pollutant Emission Notices are required for: 002 each individual emission point in a non-attainment area with uncontrolled actual emissions of one ton per year or more of any individual criteria pollutant (pollutants are not summed) for which the area is non-attainment. (Applicant is required to file an APEN since emissions exceed 1 ton per year VOC) Part B — Construction Permit Exemptions 002 Applicant is required to obtain a permit since unconfrolled VOC emissions from fhis facility are reater fhan fhe 2. 0 TPY threshold Re . 3, Part 8, Section II.

Up to 6-5,000 bbl internal floating roof storage tanks Operator did not know how it was going to configure the site, but knew the facility would have a maximum throughput of 127,750,000 bbl/yr. For the purpose of the application, calculations were based on "worst-case" assumption that all 6-250,000 bbl tanks would be constructed, but allowing for other tank sizes to be built as long as the total facility emissions stayed under the permitted total. On May 1 , 2015, I got an email from the consultant saying that the operator decided on their configuration of 8- 150,000 bbl internal floating roof storage tanks. They wanted to cancel the APENs for the 250,000 bbl, 100,000 bbl and 5,000 bbl tanks. I requested a cancellation notice for the 3 points. They provided a revised APEN for the 150,000 bbl tanks so that I could use that to redline the original APEN and supporting documentation via email on 5/1 /2015. Operator referred me to permit 07WE0329. Page 4 AIRS Point 002 Condensate Storage Tanks A permit will be issued because the uncontrolled VOC emissions are greater than 2 TPY (permit threshold). Operator used EPA Tanks 4.0.9d to calculate working and breathing emissions from the tanks. Flash emissions are not anticipated from these tanks (indicated on the APEN). Landing loss emissions were also calculated and included with the total VOC emissions. When determining HAP emissions from the landing losses, the operator took the ratio of the HAP/VOC from EPA Tanks and multiplied it to the total VOC emissions from the landing losses. There are 8 tanks and the EPA Tanks modeled 1 tank.
