Date: Josh Patterson VP of Operations NGL Water Solutions DJ Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 2 13159 WCR 39 Platteville, Colorado 2.0 GENERAL 2.1 SPCC Plan Description 1112.7(a)(1)l The following Spill Prevention, Control, and Countermeasure (SPCC) Plan has been developed and updated as part of a comprehensive plan to minimize the potential for oil discharges at the NGL Water Solutions C6 facility. The plan is designed to guide personnel in their oil spill prevention activities in conformance with applicable federal requirements outlined in the Code of Federal Regulations (CFR), Title 40, Part 112, for facilities with aggregate aboveground oil storage capacity greater than 1,320 gallons. The SPCC Plan is maintained at the NGL Water Solutions C6 facility for use by oil handling personnel. It is available for inspection by regulatory officials during regular business hours. 2.2 Amendment and Review Procedures 1112.5] The SPCC Plan will be amended as needed by NGL Water Solutions whenever there is a change in the facility design, construction, operation, or maintenance which materially affects the potential to discharge oil into navigable waters or adjoining shorelines. Any amendment to this SPCC Plan will be effective only if certified by a Professional Engineer in accordance with 40 CFR Part 112.3(d). In addition, NGL Water Solutions will review and evaluate the current SPCC Plan at least once every five years. As a result of such review, the SPCC Plan will be updated and modified to include more effective prevention and control technology where applicable. All plan amendments will be certified by a Professional Engineer and fully implemented within six months of the date of the facility change. SPCC Plan reviews will be documented on a review log that will be maintained with the SPCC Plan. The SPCC Review Log form is provided in Appendix A. 2.3 Facilities Not Yet Operational 1112.71 The solids processing facility described in this SPCC plan is pending construction. The first phase of construction will consist of installing 23 ASTs within the tank farm in addition to the processing tanks and equipment within the main and auxilary processing buildings. The second phase of construction will involve installing four additional 400 barrel (bbl) drilling mud tanks and four additional 400 bbl tank-bottom tanks and four additional 400 bbl off-spec tanks at an undetermined date. A detailed description of the solids processing facilities and figure illustrating the proposed facility layout are included in Appendix K. If the facility is not constructed according to the specifications of this SPCC plan, then this SPCC plan must be amended. 2.4 Deviations from Requirements 112.7(a)(2) The NGL Water Solutions C6 facility currently has no deviations from the SPCC requirements. Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 3 13159 WCR 39 Platteville, Colorado 2.5 Facility Description I112.7(a)(3)1 The NGL Water Solutions C6 facility is an oilfield water storage, recycling, and Class II injection facility. Oilfield production water with trace quantities of oil is transported to the site by tanker trucks that vary in size. The largest transport has a storage capacity of approximately 8,400 gallons. The production water delivered to the site is offloaded from the tankers on a concrete pad that slopes to the center from the east and west. The unloading pad includes a drain to collect surface runoff, which slopes for drainage into a containment sump on the north side of the unloading pad. The water offloaded from the tanker trucks is pumped directly from the transports through an offloading pump and into an enclosed 981 barrel (41,202-gallons) separator tank, where the solids are separated from the oil/water mixture. After initial separation the water is pumped into the six manifolded 21,000-gallon aboveground storage tanks (ASTs), which are identified as AST 1 through AST 6. Furthermore, an oil-rich mixture is pumped from the top of the separator tank into 36,600-gallon ASTs 9 and 10. After the oil is allowed to completely separate from the water, the oil is transferred into 21,000-gallon AST 11, and 16,800-gallon ASTs 12 and 13. The water from ASTs 1 through 6 and the separated production water from ASTs 9 and 10 are transferred to the pump house for filtration and treatment prior to injection or further recycling. The treated water is then transferred to 33,600-gallon ASTs 7 and 8, and subsequently pumped into the on-site injection well or further conditioned and treated for subsequent industrial Exploration and Production (E&P) application. The water treatment and conditioning process occurs after all fluids have passed through the existing facility processes including filtration. As an alternative to disposal via deep well injection a portion of those fluids in the "clean" fluid tanks (ASTs 7 and 8) is diverted into pre-treatment tanks (PT-tanks 1 through 6) prior to being routed through the treatment and conditioning building or the solids processing facility. Each tank in this treatment building (ASTs A through G) contains a proprietary process that breaks down and removes those constituents that prohibit industrial re- use. The chemicals utilized in the water treatment process are inert after they have been spent in the treatment and conditioning process. Some dissolved solids are precipitated via a chemical softening process, where thereafter, the total suspended solids are removed via coagulation and flocculation processes. The sediment is drained to a filter box, which enables the sediment to be disposed of at a licensed landfill. Treated and conditioned water is transferred into the recycled water diked area for subsequent loading into water trucks for utilization in industrial E & P application. No waste fluid is generated during the water recycling process. Since the diminutive possibility of the introduction of oil into the water conditioning and treatment tanks, or the solids processing facility exists the water treatment tanks are included in the facility SPCC plan. Overall, the initial treatment facility consists of a concrete unloading pad, pump house, office, storage tent, injection well, and a concrete secondary containment dike that stores six 21,000-gallon production water ASTs (AST-1 through AST-6), two 33,600-gallon treated water ASTs (AST-7 and AST-8), two 21 ,000-gallon "skim tank" ASTs (AST-9 and AST-10), one 21,000-gallon oil AST (AST-11), and two 16,800-gallon oil tanks (AST-12 and AST-13). Furthermore, Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 4 13159 WCR 39 Platteville, Colorado one, 41,202-gallon raw production water AST (unloading/offloading tank) is located within the secondary containment of the concrete unloading pad. Additionally, one 12,238-gallon sump tank located to the north of the unloading pad collects water from drains located in the pump house, AST secondary containment, and a drain which traverses the center of the unloading pad. Other oil containers at the facility with a capacity of 55-gallons or greater include one 55-gallon drum containing gear oil which is located inside the pump house. The oil is used for maintenance of the facility pump equipment. The water treatment and conditioning and process building involves seven ASTs ranging in size from 2,500-gallons to 7,500-gallons (AST-A through AST-G). Furthermore, the water recycling concrete secondary containment dike contains six pretreatment tanks (PT-1 though PT-6), two waste tanks (waste-1 and waste-2), and six recycled water tanks (AST-R1 through AST-R6). The solids processing facility will enable NGL Water Solutions to process drilling mud and tank-bottom fluids laden with sediment. The solids processing facility will receive two main types of waste 1 .) drilling mud, and 2.) tank bottoms. Trucks will offload drilling mud waste into offload shakers that will assist in removing large particles from the fluid. The initial solids generated will be transferred into a solids dumpster and eventually to a licensed landfill. The drilling mud fluids will be stored in four ASTs within the tank farm (four additional tanks will be installed at a later date). Drilling mud fluids will then enter a reaction tank where coagulant is mechanically added followed by a decanter centrifuge tank where a polymer is mechanically added that aids in removing fine particles from the fluid. Solids are transferred from the decanter centrifuge to the solids storage building for subsequent loading onto trucks and eventually to a licensed landfill. Water from the drilling mud enters the capture tanks and is then pumped out to the water tanks in the tank farm where it may be transferred to the existing water recycling plant or salt water disposal. Tank bottoms are offloaded and pumped into the four tank-bottoms ASTs within the tank farm (four additional tanks will be installed at a later date). Fluids are then pumped from the ASTs through heat exchangers and into the reaction tank inside the processing building. The fluid then enters the reaction tank where coagulant is mechanically added to aid in the sedimentation process. The fluid is pumped into the centrifuge where a polymer is mechanically added in-line to further aid in the removal of solids from the fluid. The fluids may also be processed through a filter press whereby solids will be transferred to the solids storage building for subsequent loading onto trucks and eventually to a licensed landfill. The fluids will continue to move into the centrate/filtrate tanks where oil and water separation occurs. Oil is pumped out to the six oil tanks in the tank farm where it is eventually sold and delivered offsite. The water is pumped out into the four water tanks within the tank farm and pumped to the existing on-site water recycle facility. The solids processing facility encompasses eight treatment areas including the shale shakers, drilling mud tanks, tank bottoms, heat exchangers, reaction tanks, centrifuge/filter press, centrate/filtrate tanks, water and oil tanks, and a conveyor belt for transferring solids to the solids storage shed with tank sizes ranging from 420-gallons to 35,280-gallons. Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 5 13159 WCR 39 Platteville, Colorado All facility ASTs are within secondary containment areas sized to hold the contents of the largest tank in each area with excess freeboard (excluding ASTs within covered processing buildings) for precipitation. The secondary containment structures are designed to be adequately impervious to prevent oil from escaping before cleanup occurs. The main solids processing building involves five ASTs ranging in size from 6300-gallons to 16,800-gallons (reaction tanks and centrate/filtrate tanks; ASTs 40-01 thru 40-02 and ASTs 50-03 thru 50-05). Furthermore, the solids processing facility main secondary containment area contains four drilling mud tanks (AST 10-01 thru AST 10-04), four tank-bottom tanks (AST 20-01 thru 20-04), four ofd spec tanks (AST 30-01 thru 30-04), six oil tanks (AST 70-01 thru 70-06) and five water tanks (AST 60-01 thru 60-05). Additionally, the auxiliary process building includes one reverse osmosis permeate tank and one hot brine tank. The facility is located in the Northeast '/4 of the Southeast '/4 of Section 30, Township 3 North, Range 65 West, in Weld County, Colorado. The facility is located approximately 1 ,000 feet north of the intersection of Weld County Road (WCR) 28 and WCR 39. The facility is surrounded by grazing land and oil and gas operation areas. The regional topography is relatively level with a regional drainage to the east-southeast toward the Beebe Seep Canal. The subject property is relatively level with a gradual grade to the southeast. Surficial runoff within the concrete unloading areas will be captured within the pad drain. Furthermore, surficial runoff within the concrete recycled water loading area and solids processing facility will drain and be captured within the recycled water containment dike and solids processing facility containment dike, respectively. All other site runoff is generally sheet flow towards WCR 39 to the east or WCR 28 to the south. Most precipitation will infiltrate into the silty to sandy surficial soils surrounding the facility. The nearest significant water body is the Milton Reservoir, which is approximately 3 miles northeast of the site. Site location and area topographic and surface water features are depicted on Figure 1 (Topographic map). General site conditions and facility details are shown on Figure 2. 2.6 Facility Storage 1112.7(a)(3)(i)1 The following table describes ASTs at this facility: # of AST s Capacity Contents Construction (Tank IDs) (gallons) System production Single-wall steel shop fabricated horizontal 1 41 ,202 water unloading tank AST elevated on skids within unloading pad (offloading tank) (water and oil containment. mixture) 6 Pre-filter production Single-wall steel shop fabricated vertical ASTs (ASTs 1 -6) 21,000 water within concrete secondary containment Oil with some 2 Single-wall fiberglass shop fabricated vertical (ASTs 9-10) 33,600 production water AST within main concrete containment.

NGL Water Solutions only accepts disposal water when there is adequate capacity in the tanks to receive fluid. Monitoring of the transfer operation is done visually, with strict attention being paid to the volume received in accordance with available tank capacity. Inspection of automatic tank level sensors and sight confirmation of tank liquid levels are performed approximately every two hours with additional inspection as needed. Unloading procedures consist of two transfer pumps situated on the concrete secondary containment pad that transfers fluid from the unloading tanker into the unloading AST. Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 8 13159 WCR 39 Platteville, Colorado After the general separation of the oil and water in the unloading tank, the oil is transferred into one of two skim tanks and the production water is transferred into one of six manifolded ASTs. As aforementioned, tank filling does not begin until the plant operator has verified and documented the ullage (available capacity) based on electronic gauge measurements and sight confirmation. In addition, electronic gauges are utilized that automatically shut down the pump transfer when tank volume capacity reaches 90%. After separation of the oil from the production water in the skim tanks, the water is transferred to the six manifolded production water ASTs, and subsequently transferred to the pump house for filtration. The oil is transferred to one of three oil tanks where it is pumped into transport trucks on a regular basis. After filtration of the production water, the water is transferred to the treated water ASTs, and then back through the pump house where it is injected into the subsurface via the injection well located west of the pump house. Any water spilled within the pump house during pump operation or maintenance flows into one of two floor drains which drain into the sump located adjacent to the unloading secondary containment area. An example Ullage Log is provided in Appendix B. In addition to the general facility operations described above, water may be further treated and conditioned in the treatment and conditioning building for potential E & P process re-use. Any spilled fluids within the water treatment and conditioning building will be drained back into the existing facility treatment process. Furthermore, the solids processing facility is equipped with level and atmosphere sensing alarms, which are monitored on a consistent basis to ensure proper operation. Each tank within the recycling facility process is secondarily contained to prevent discharge of exploration and production water. A detailed description of the solids processing facility along with the proposed layout is included as Appendix K. NGL Water Solutions requires all drivers to comply with DOT regulations in 49 CFR Part 177 regarding tank loading and unloading procedures. DOT requirements are provided in Appendix C. The following procedures are implemented when ASTs are being loaded: O Vehicle's motor and lights are turned off, and the parking brake is set ❑ The driver does not remain in the vehicle ❑ Outlet valves are closed O Grounding procedures are followed ❑ Ungrounded objects are removed from loading/unloading areas ❑ Flow is started slowly. The fill pipe is touching both the truck hatch and bottom of compartment ❑ Transfer operator is present and attentive After loading is complete, the following procedures are followed: ❑ All loading valves are closed and loading arms disengaged. Signs of spillage are noted and remedial action taken if necessary O All hatches are closed tightly Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 9 13159 WCR 39 Platteville, Colorado ❑ Internal safety valves are closed 2.8 Discharge Controls 112.7(a)(3)(iii)1 The ASTs and all associated piping and equipment are located within a concrete diked secondary containment, or the unloading pad, which will contain and control any potential discharges from the tanks, equipment or transport trucks. A catastrophic spill would further be contained by the impermeable overflow basin located to the east of the unloading pad. Furthermore, any spills occurring within the pump house or treatment and conditioning building flow to the floor drains, which drain to the unloading area sump, or the pretreatment tanks, respectively. The proposed solids processing facility is designed to contain process water through every step in the recycling process. Tanks are either contained within an impermeable secondary containment berm or are double walled to prevent discharge. The cargo tankers could be considered mobile or portable oil storage tanks; however, the tankers are not owned by NGL Water Solutions and are generally situated on the unloading pad for short periods of time during deliveries. The design of the unloading pad is such that liquids would be contained on the pad or diverted to the containment drain, which flows into the containment sump that is automatically pumped into the unloading tank as needed. NGL Water Solutions maintains spill response oil absorbent materials readily available at the facility that can be rapidly deployed to contain and abate potential discharges outside the secondary containment areas. NGL Water Solutions instructs oil handling personnel to assure that all 55-gallon oil drums are stored inside the pump house, and that drum openings are sealed appropriately when not in use to prevent spills. NGL Water Solutions assures that all transfer equipment is compatible with the products being dispensed. Furthermore, drum fittings are securely attached to the appropriate bung openings and operated according to manufacturer recommendations. 2.9 Countermeasures: Discovery/Response/Cleanup 1112.7(a)(3)(iv)1 NGL Water Solutions employees are aware of the need to report all spills of petroleum products to management. In the event of a large spill requiring emergency response (i.e., spill spreads beyond the immediate spill area, enters surface water, requires special training or equipment, poses a danger of fire or explosion), emergency personnel from the Platteville-Gilcrest Fire Department and other local emergency authorities are on hand by calling 911 . Additionally, NGL Water Solutions maintains an ample inventory of oil absorbent materials, such as booms, pads, and granular absorbent, readily available on-site to respond to spills. Equipment, such as tractors with excavation attachments, and manual tools, such as shovels and rakes, are located at the facility for use in containing and cleaning up potential spills. In the event of a spill outside the secondary containment areas, oil absorbent materials will be placed along the leading edge of the flow path and, if needed, excavating equipment will be used to erect soil berms to contain spills on-site until cleanup measures are completed. NGL Water Solutions instructs all operations personnel who operate the AST systems and are involved with oil handling activities on the location of the spill containment materials and deployment measures needed to contain and clean up spills. Spill response will be initiated as soon as possible to stop Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 10 13159 WCR 39 Platteville, Colorado additional spillage and to implement containment measures. Discovery, response, and cleanup activities are described in more detail in the following sections. 2.10 Disposal 1112.7(a)(3)(v)l The final operation in spill response and cleanup is the disposal of impacted materials. Any plan used by NGL Water Solutions for disposal must be coordinated through the Colorado Oil and Gas Conservation Commission (COGCC). Media impacted by a spill must be disposed at a facility approved by the Colorado Department of Public Health and Environment (CDPHE), or other appropriate regulatory agency, to receive the type of waste being shipped. NGL Water Solutions will submit follow-up written reports to the appropriate agency at times commensurate with requirements of the agency. Sediments removed via the water treatment and conditioning system will be disposed of at a CDPHE licensed landfill. Each waste shipment must be documented using appropriate waste manifest or bill-of- lading forms. 2.11 Notification Phone List I112.7(a)(3)(vi)1 In the event of leakage or spills, the individuals and/or companies listed in Appendix D are to be notified. Spills ultimately reaching navigable waters in harmful quantities as defined by 40 CFR 110.3 (that which violates applicable water quality standards or causes a sheen on the water surface) are required to be reported under 40 CFR 110.6. If a petroleum release occurs and is greater than 840-gallons (20 bbls), it must be reported to the following regulatory agencies within 24 hours: Colorado Oil and Gas Conservation Commission 1120 Lincoln Street, Suite 801 Denver, Colorado 80203 303-894-2100 {Ifa petroleum release occurs and is greater than 5 barrels (210 gallons), it must be reported within 10 days Colorado Department of Public Health and Environment (CDPHE) 4300 Cherry Creek Drive South Denver, Colorado 80246-1530 (303) 692-3425 If the release reaches navigable water, the following agency must be contacted: National Response Center Washington, DC 800-424-8802 (24-hour phone) 2. 12 Discharge Notification Form 1112.7(a)(4)l An example form for spill documentation and reporting is provided in Appendix E. When contacting regulatory agencies, the following information should be provided: Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 11 13159 WCR 39 Platteville, Colorado O name and owner/operator of facility ❑ responsible company/person, including mailing address and telephone number O name of person reporting the release ❑ date and time of release legal description of release location ❑ type of substance ❑ amount of substance released ❑ waterway affected, including amount reaching water ❑ cause of release ❑ action taken to control, contain, and remove release ❑ other pertinent information specific to the release In accordance with 40 CFR Part 112.4(a), if NGL Water Solutions has a discharge to navigable water of more than 1,000 gallons of oil in a single event or discharges more than 42 gallons of oil in each of two discharges occurring within any twelve month period, NGL Water Solutions will submit the following information to the EPA Regional Administrator within 60 days from the day of the discharge. ❑ Name of the facility ❑ Callers name ❑ Location of the facility ❑ Maximum storage or handling capacity of the facility and normal daily throughput ❑ Corrective action and countermeasures taken, description of equipment repairs and replacements ❑ Description of the facility, including maps, flow diagrams, and topographic maps, as necessary ❑ Description of the cause of the discharge, including a failure analysis of the system or subsystem that failed ❑ Additional preventative measures taken or contemplated to minimize the possibility of recurrence I I Any other information as the Regional Administrator may reasonably require pertinent to the Plan or discharge 2.13 Discharge Procedures 1112.7(a)(5)1 After identifying and locating a spill, the necessity for and feasibility of effective containment can be assessed. Containment must be initiated as soon as possible to prevent undue spreading of released product. The first action should be the elimination of any additional spillage. This may be accomplished by shutting off a pump or valve, placing a cap or a plastic or epoxy patch over the leak, putting a temporary plug in a puncture or tear, righting an overturned container, or other appropriate action. Oil absorbent materials maintained at the facility will be used to contain and clean up spilled product. If required, excavation equipment and/or manual tools, such as shovels and rakes, will be used to erect earthen berms along the Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 12 13159 WCR 39 Platteville, Colorado leading edge of the spill to prevent spreading. Materials recovered during cleanup will be placed in appropriate containers or stockpiled using an impermeable liner and cover (such as polyethylene sheeting) to prevent cross- contamination with unexposed media prior to disposal. If free product is present or if the spill reaches surface water, the spill must be contained and removed. Mechanical methods of spill removal include suction hoses, excavation, the use of skimmers, and sorbent materials. The use of chemical or biological collecting agents is discouraged and can only be used with prior approval from both state and federal regulatory officials. NGL Water Solutions instructs all personnel who operate the AST systems on the location of the spill containment materials and deployment measures needed to contain and clean up a potential spill. 2.14 Discharge Prediction f 112.7(b)1 A review of operations at the NGL Water Solutions C6 facility indicates a low potential for equipment failure. The NGL Water Solutions facility has had no reported spills of treated production water or oil, which qualified as "spill event" under the federal definition. The following table describes storage containers and associated equipment where potential discharges could occur. The table includes predictions of failure types, estimated volume, flow rate and the direction of flow, which could be discharged from the facility as a result of each type of major equipment failure and general secondary containment notes. ` Type of Failure I.

The water is pumped directly from the transports into the unloading/offloading AST, where the condensate, sediment and production water are initially separated. If a spill were to occur, the design of the unloading pads are such that liquids would be contained on the pads and in the drains and containment sumps adjacent Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 15 13159 WCR 39 Platteville, Colorado to the unloading areas. Transfer pumps and piping used to fill all tanks are within the secondary containment dike or unloading pad containment. The combined secondary containment of the unloading pad, unloading pad sump, and the overflow basin have the capacity to contain the contents of the unloading tank plus freeboard allowance. Secondary containment for oil transfer activities from ASTs 11 through 13 are provided by the concrete unloading/loading pad. Furthermore, overfills, valve or connection failures would be contained within the AST secondary containment or unloading/loading pad. Loading and unloading of 55-gallon oil drums is performed on the unloading/loading pad and transferred into the pump house. The building walls and readily available spill response absorbent materials maintained on-site provide secondary containment for potential discharges that may occur inside. Furthermore, two drains are situated within the pump house to allow spills to drain to the unloading pad sump. Secondary containment for production water filtration within the pump house is provided by the 12,290-gallon sump, which is located in the unloading secondary containment area. Two drains located within the pump house flow through underground schedule 80 PVC piping into the sump. The drain is positioned to collect any production water or oil spillage that may occur during equipment maintenance including changing system filters or adjusting/repairing system piping within the pump house. The liquid level in the sump is equipped with a float valve that automatically pumps fluid into the unloading tank as needed. Secondary containment for the water treatment and conditioning tanks to the southwest of the pump house is provided by a concrete secondary containment dike surrounding all of the water treatment holding tanks. Furthermore, the processing building is designed with a four-inch concrete dike within the foundation of the building perimeter, which provides secondary containment for any catastrophic rupture of the treatment and processing tanks. Additionally, minor spills are collected by a drain that is positioned below the water treatment and conditioning process tanks. The drain empties to a small sump that pumps the water into the pretreatment storage tanks. Secondary containment for the solids processing facility and pre-treatment frac-tanks are provided by plastic lined secondary containment berms or secondarily contained tanks. Secondary containment for the solids processing facility and associated tanks is provided by an 18-inch tall concrete secondary containment dike surrounding all of the water and oil holding tanks. Furthermore, the main and auxiliary solids processing buildings are designed with the floor six inches lower than the foundation and grade, which provides secondary containment for any catastrophic rupture of the treatment and processing tanks. The auxiliary process building is designed with a six-inch sunken concrete dike within the foundation of the building perimeter. There is one drain for the processing facility building that traverses the length of the building located in the center designed to receive any and all liquids and thus pumped out of the facility via a sump pump on the eastern end. The main tank battery contains two floor sinks that drain into a sump located at the southwest corner of the tank battery. Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 16 13159 WCR 39 Platteville, Colorado Secondary containment for water transfer activities from the four truck lanes are provided by the concrete unloading/loading pad. Furthermore, overfills, valve or connection failures would be contained within the concrete secondary containment or unloading/loading pad. Readily available spill response absorbent materials maintained on-site provide additional secondary containment for potential discharges that may occur inside. Additionally, one drain is situated within the pad to allow spills to drain directly to the unloading pad sump. In the event of a spill outside the secondary containment areas, oil absorbent materials maintained on-site will be placed along the leading edge of the flow path and, if needed, excavating equipment will be used to erect soil berms to contain spills on-site until cleanup measures are completed. Furthermore, an overflow basin is positioned to contain additional spills to the east of the unloading pad for the water recycling facility. The overflow basin is designed with a holding capacity of 22,443 gallons. NGL Water Solutions instructs all operations personnel who operate the AST systems and are involved with oil handling activities on the location of the spill containment materials and deployment measures needed to contain and clean up spills. All secondary containment systems at the facility are sized to hold the volume of the largest predicted spills associated with loading and unloading activities. Furthermore, the secondary containment systems are adequately impervious to contain spilled oil on-site until clean- up occurs. 2.16 Statement of Impractibility 1112.7(d)] Not applicable; secondary containment is provided for all petroleum storage containers at the facility. 3.0 INSPECTIONS, TESTS AND RECORDS 3.1 Inspections and Record-Keeping ( 112.7(e) Inspections are an integral part of NGL Water Solutions operations. As described in more detail in Section 9.6, the AST systems are visually inspected each month and annually to ensure that there has been no failure of the tanks or associated equipment. Periodic certified inspections are also performed on the tanks, piping, and transfer equipment. Storage tank inspection reports which have been completed are signed by the appropriate supervisor or inspector and are made part of the current SPCC Plan. NGL Water Solutions management is responsible for all inspection reporting and documentation procedures. These records are kept on file with the SPCC Plan for a minimum period of three years. Inspection and recording forms are provided in Appendix F. Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 17 13159 WCR 39 Platteville, Colorado 4.0 PERSONNEL TRAINING 4.1 Personnel Instruction 1112.7(0(1)1 The AST systems are used only by a few employees who are properly trained in the operation and maintenance of the ASTs and associated equipment. Moreover, specific training to instruct all operations personnel on the contents and requirements of the SPCC Plan is regularly conducted and training is documented. Since the design of the system is relatively simple and employee turnover is low, subsequent training is performed only occasionally. 4.2 Designated Individual for Spill Prevention 1112.7(0(2) The designated individual for spill prevention and reporting at the NGL Water Solutions C6 facility is Mr. Daniel Garcia, who can be contacted at 970-397-9156 (cell), or 970-356-5560 (office). 4.3 Spill Prevention Briefings 1112.7(0(3)1 NGL Water Solutions schedules and conducts spill prevention briefings at least annually, in coordination with regularly scheduled safety meetings, for all personnel involved with oil handling operations to assure adequate understanding of the SPCC Plan. These briefings highlight and describe spill events or failures, malfunctioning components, and recently developed precautionary measures. Employees acknowledge attendance and understanding of these briefings with their signatures on an attendance form. An SPCC training attendance form is provided in Appendix G. 5.0 SECURITY 1112.7(g)1 5. 1 Securing and Controlling Access Security and access control is provided by a fence that surrounds the entire NGL Water Solutions C6 facility. In addition, the facility accepts E&P production water from 7am to 10 pm; however, the facility is manned and operates 24 hours per day, 7 days per week and personnel entering the facility are required to check in at the main office. 5.2 Securing Master Flow/Drain Valves NGL Water Solutions locks master flow/drain valves on the applicable ASTs when not in use, or in standby mode for extended periods of time. 5.3 Preventing Unauthorized Access to Starter Controls Starter controls for the AST oil transfer pump are located in a control panel which is locked with switches in the off position when not in use, or in standby mode for extended periods of time. NGL Water Solutions limits access into the control panel to authorized personnel trained in the operation of the AST system. Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 18 13159 WCR 39 Platteville, Colorado 5.4 Securing Loading/Unloading Connections Loading/unloading pipe connections are securely capped and valves locked when not in use. 5.5 Security Lighting Overhead lighting is present in all of the oil and production water storage/transfer areas and outlying areas that will assist in the discovery of discharges occurring during hours of darkness both by operating personnel and non- operating personnel and to deter acts of vandalism. 6.0 TANK TRUCK LOADING/UNLOADING 6.1 Secondary Containment for Loading/Unloading Areas Including Racks 1112.7(h)(111 The ASTs at the facility do not include loading/unloading racks. As described in Section 2. 14, all loading and unloading connections and equipment on the ASTs are within the secondary containment dike and loading/unloading areas. If a spill occurs from a tanker truck outside the containment areas, NGL Water Solutions maintains readily available and ample quantities of absorbent materials and equipment on-site that can be rapidly deployed to contain and abate any potential spill on-site. Supplemental secondary containment is also provided by the overflow basin. 6. 2 Warning/Barrier Systems 1112.7(h)(2)1 Signs warning drivers to disconnect transfer lines before departure are posted in unloading/loading area. 6. 3 Bottom Drains of Vehicles Examined 112.7(h)(3) NGL Water Solutions assures that prior to filling and departure of any tank truck, the lowermost drain and all outlets of such vehicles are closely examined for leakage and, if necessary, tightened, adjusted, or replaced to prevent liquid leakage while in transit. 7.0 OTHER GENERAL REQUIREMENTS 7. 1 Brittle Fracture/Other Failure Evaluation — Field Constructed Aboveground Containers 112.7(i) The NGL Water Solutions C6 facility does not include field-constructed ASTs. 7.2 Conformance with Stricter State Rules 1112.7(i)1 No stricter State discharge prevention and containment procedures are applicable to this facility.

In the event of excess precipitation accumulation, minor spills, or AST or piping discharges within the secondary containment areas, fluids are allowed to drain into the containment sump via a drain located within the secondary containment, or pumped into processing tanks. Furthermore, precipitation onto the concrete unloading/loading pad flows into a central drain, which flows into the containment sump and is subsequently pumped into the unloading AST. Precipitation which accumulates in the concrete overflow basin located to the east of the unloading pad is only discharged after it is visually checked for the presence of an oil sheen. Water is drained with a drainage valve which remains in the closed position at all times. Each time water is drained from diked areas the drainage is documented. A Dike Water Drainage Log is provided in Appendix H. 8.2 Dike Drainage Valves - Manual, Open/Closed Designed 1112.8(b)(2)1 Drainage valves are located on the drain between the AST secondary containment and the unloading pad sump, and on the effluent drain of the overflow catchment basin. Dike drainage valves utilized at the facility are manual open/close designed. 8.3 Drainage System for Undiked Areas 112.8(b)(3) Secondary containment is provided for all aboveground tanks, piping and tanker truck transfer areas to prevent discharges to storm drainages outside the secondary contained areas. 8.4 Final Discharge Diversion System 1112.8(b)(4) The final discharge diversion system employed at the water recycling facility is the concrete overflow basin that provides an additional 22,443 gallons of secondary containment capacity. 8.5 Backup Pump for Lift Station and Transfer Systems 1112.8(b)(5)1 NGL Water Solutions does not operate drainage lift stations at the C6 facility. Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 20 13159 WCR 39 Platteville, Colorado 9.0 BULK STORAGE TANKS 9.1 Containers Compatible with Materials Stored 112.8(e)( 1 ) The ASTs and portable containers used for storage of water and petroleum products at the NGL Water Solutions facility are shop manufactured for their intended use. The containers are constructed with materials compatible with the products stored and conditions of storage, such as pressure and temperature. 9.2 Secondary Containment 1112.8(c)(2f Main Secondary Containment The oil and production water ASTs are within a concrete paved and diked secondary containment. The secondary containment is designed with adequate capacity to hold the volume of the largest tank (33,600-gallons) plus freeboard allowance for precipitation. The total calculated holding capacity of the containment is approximately 84,654 gallons.

Each secondary containment system at the NGL Water Solutions C6 facility is designed to be impervious to contain spills from the largest tank without loss of oil or production water until cleanup measures are implemented. NGL Water Solutions assures that excess precipitation is removed from the secondary containments, where applicable, in order to maintain adequate spill retention volume for the tanks. Secondary containment volume calculations are presented in Appendix I. 9.3 Rainwater Drainage Procedure 1112.8(c)(3)1 Precipitation that accumulates within the diked areas is pumped into the production water or recycled water pre- treatment holding tanks. Precipitation accumulating in the overflow basin is drained after inspection of the accumulated water for the absence of oil or a visible sheen. 9.4 Buried Metal Tanks Corrosion Protection i112.8(c)(4)I The facility does not currently operate buried tanks. Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 22 13159 WCR 39 Platteville, Colorado 9.5 Partially Buried Tanks Protected Against Corrosion 112.8(O(5) The facility does not operate partially buried tanks. 9.6 Integrity Testing 1112.8(O(611 NGL Water Solutions assures that the ASTs and associated equipment are maintained in good condition. The ASTs, valves, transfer equipment, and aboveground piping components are readily accessible for visual inspection. Preventive spill measures include regular periodic inspections of the storage tanks and associated equipment and secondary containment systems following guidelines of the Steel Tank Institute (STI) Standard for the Inspection of Aboveground Storage Tanks SP001 September 2011 5th Edition. Based on the tank configurations, tank volumes, release prevention barrier provided the secondary containment structures, and spill control provided by the secondary containment diking, these activities include the following: C On a monthly basis, the owner inspects the tanks, piping, and associated equipment for evidence of leakage. If needed, gaskets are replaced and threaded connections are tightened. Secondary containment areas are checked for the presence of spills or leaks, which are removed if present. The secondary containment sump pumps are checked to assure they are operable and water transfer piping is unobstructed. Tank gauge calibrations are checked by obtaining stick readings to verify gauge readings. Overfill equipment is tested to assure proper operation. On an annual basis, the owner inspects the condition of the tank containment structure. Tank foundations and supports are inspected for evidence of settling, cracking or distortion, proper water drainage and grounding. Inspections of the AST exteriors are performed to identify and repair damage to the tanks or surface coatings. Bolts on flanged manways, piping and equipment are inspected for tightness, wear and corrosion. Normal operating and emergency vents are inspected for proper operation and cleaned if needed. Tank liquid level sensing and overfill prevention devices are tested for proper operation. Electrical equipment, including grounding devices, control boxes and lights are inspected for proper operation. At a maximum 20 year interval, formal external inspections are performed by a Certified Tank Inspector on all ASTs with volume capacities larger than 5,000-gallons. The formal inspections generally include items covered in the owner's monthly and annual inspections as well as comparison of tank conditions in relation to the original construction standards. In addition, leak detection equipment is checked to confirm proper operation. Any leaks discovered during inspection are promptly evaluated and reported to the General Manager. NGL Water Solutions assures that personnel who operate, maintain and inspect the AST systems are properly trained in the operation and maintenance of the systems, and characteristics of the fluids stored, which helps to reduce the probability for a spill. As noted in Section 3. 1, monthly and annual inspection documentation forms are provided in Appendix F. Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 23 13159 WCR 39 Platteville, Colorado 9.7 Internal Coils I112.8(c)(7)1 Internal coils are present in the hot brine tank. Steam return and exhaust lines are part of a closed loop system so that any oil that accumulates in the steam is not discharged. The tank and associated piping are inspected on a monthly basis to detect leaks or malfunction of the heating element. 9.8 Engineered to Avoid Discharges 1112.8(c)(8)1 NGL Water Solutions only accepts disposal water when there is adequate capacity in the tanks to receive the product. Furthermore, NGL Water Solutions only treats and conditions system water when there is adequate capacity available in the treatment and conditioning system tanks. Monitoring of the transfer operation is done visually, with strict attention being paid to the volume received in accordance with available tank capacities. Checking automatic tank level sensors and sight confirmation of tank liquid levels are performed approximately every two hours with additional confirmation as needed. Tank filling does not begin until the plant operator has verified and documented the ullage (available capacity) based on tank monitoring sensors and sight confirmation. Furthermore, all system processing tanks are equipped with overfill pump shut off sensors, which automatically shut down the pumps once tanks reach 90% available capacity. All production and treated system water transfers and oil transfers are performed within secondary containment areas. All areas where production water and oil are transferred and stored are on concrete pavement, which is sloped to an interior drainage system and/or diked, or within a lined and secondarily contained area. The engineered design of the facility forms a closed loop system to contain spills and precipitation within the secondary containment areas and prevents discharges to the surrounding environment. 9.9 Plant Effluent Discharges into Navigable Water 1112.8(c)(9)1 The facility does not have plant effluent discharges to navigable waters. 9.10 Oil Leaks Promptly Corrected I112.8(c)(10)1 Any oil or production water leaks identified through routine inspection are promptly corrected, reported to management, and abated. 9.11 Mobile or Portable Oil Storage Tanks I112.8(c)(11)1 The cargo tankers could be considered mobile or portable oil storage tanks; however, the tankers are not owned by NGL Water Solutions and are only on site for short periods during fluid transfer activities. Portable oil storage containers at the facility include one 55-gallon drum of gear oil for pump house maintenance activities. The drum is stored inside the pump house and secondary containment for the oil storage container is provided by the concrete floor, floor drains to the unloading sump, and readily available spill response materials. Oil-handling personnel are instructed to maintain Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 24 13159 WCR 39 Platteville, Colorado appropriate seals and plugs on the container when not in use to prevent spills. If a spill occurs, spilled product will be contained within the building walls and cleaned up with readily available oil absorbent materials. 10.0 FACILITY TRANSFER OPERATIONS 10. 1 General General safety features which are applicable to maintaining the integrity of transfer operations include: Valves and pipelines are examined monthly to assess the condition of the transfer equipment; and ❑ If corrosion damage is found, additional examination and corrective action are taken as indicated by the magnitude of the damage. 10.2 Buried Pipe Installations [112.8(d)(1)1 Most facility piping is aboveground and readily visible for inspection. However, piping connecting the pump house and secondary containment drains to the containment sump is underground and piping connecting the solids processing facility to the water recycling facility is underground. All underground piping is constructed with schedule 80 PVC, which is not susceptible to corrosion and does not require cathodic protection. If a section of buried pipe is exposed for any reason, it will be carefully inspected for deterioration. If deterioration or damage is found, additional examination and corrective action will be taken as indicated by the magnitude of the damage. 10.3 Terminal Pipe Connections Capped or Blank Flanged 1112.8(d)(2)1 There is no out-of-service piping associated with the AST systems. The terminal pipe connections where the tanker truck connects to unload oil from ASTs 11 through 13 are securely capped when not in use, are located inside secondary containment, and are labeled to identify what types of product are to be transferred. 10.4 Aboveground Pipe Supports I112.8(d)(3)1 NGL Water Solutions maintains adequate bracing on aboveground pipe runs to avoid excess movement that can cause stress and abrasion. Piping on the ASTs is of heavy gauge steel construction and is securely attached with threaded fittings to the tank and ground. 10.5 Testing and Inspection of Aboveground Pipes and Valves 1112.8(d)(4)j As discussed in section 9.6, valves and piping are examined monthly to assess the condition of the transfer equipment. The dispensing system equipment is maintained in good condition. If corrosion damage or leakage at valves or pipe connections is found, additional examination and corrective action will be taken commensurate with the magnitude of the damage. Spill Prevention Control and Countermeasure Plan October 30, 2014 NGL Water Solutions DJ, LLC C6 Facility Page 25 13159 WCR 39 Platteville, Colorado 10.6 Warning for Trucks of Pipes [112.8(d)(5) No aboveground piping is exposed outside of the secondary containment, or exposed to vehicular traffic. The unloading pumps and associated piping are protected by steel bollards. NGL Water Solutions instructs personnel operating in the unloading area to be aware of piping and pumping equipment and to use caution when approaching the area. 11.0 SUBSTANTIAL HARM [112.20(e)] 40 CFR 112.20 (f)(1) lists criteria under which "a facility could, because of its location, reasonably be expected to cause substantial harm to the environment by discharging oil into or on the navigable waters or adjoining shorelines. . ." if it meets any of the listed criteria. NGL Water Solutions does not meet the listed criteria, including: (1) does not transfer oil over water; and (2) has a total oil storage capacity of less than one million gallons. Because of the design of the tanks, limited spill history at the facility, no proximity to drinking water intakes, and the well- trained personnel at this facility, no Facility Response Plan should be required. The required Certification of Applicability of the Substantial Harm Criteria, Part 112.20, Appendix D, Attachment C-II, has been completed and is maintained at the facility in Appendix J of the SPCC Plan.

A person who loads or unloads hazardous materials into or from a transport vehicle or vessel shall comply with the applicable loading and unloading requirements of parts 174, 175, 176, and 177 of this subchapter. [Arndt. 173-94, 41 FR 16064, Apr. 15, 1976] 174.67 Tank car unloading. a) In unloading tank cars, the following rules must be observed (see subpart F of this part for gases): 1) Unloading operations must be performed only by reliable persons properly instructed in unloading hazardous materials and made responsible for careful compliance with this part. 2) Brakes must be set and wheels blocked on all cars being unloaded. 3) Caution signs must be placed on the track or cars to give necessary warning to persons approaching the cars from the open end of a siding and must be left up until after the cars are unloaded and disconnected from the discharge connection. The signs must be of metal or other comparable material, at least 30 cm (12 inches) high by 38 cm (15 inches) wide in size, and bear the words, "STOP — Tank Car Connected", or "STOP — Men at Work", the word "STOP" being in letters at least 10 cm (3.9 inches) high and the other words in letters at least 5 cm (2 inches) high. The letters must be white on a blue background. 4) Before a manhole cover or outlet valve cap is removed from a tank car, the car must be relieved of all interior pressure by cooling the tank with water or venting the tank by raising the safety valve or opening the dome vent at short intervals. However, if venting to relieve pressure will cause a dangerous amount of vapor to collect outside the car, venting and unloading must be deferred until the pressure is reduced by allowing the car to stand overnight or otherwise cooling the contents. These precautions are not necessary when the car is equipped with a manhole cover which hinges inward or with an inner manhole cover which does not have to be removed to unload the car, and when pressure is relieved by piping vapor into a condenser or storage tank. b) After the pressure is released, the seal must be broken and the manhole cover removed as follows: 1) Screw type. The cover must be loosened by placing a bar between the manhole cover lug and knob. After two complete turns, so that vent openings are exposed, the operation must be stopped, and if there is any sound of escaping vapor, the cover must be screwed down tightly and the interior pressure relieved as prescribed in paragraph (a)(4) of this section, before again attempting to remove the cover. 2) Hinged and bolted type. All nuts must be unscrewed one complete turn, after which same precautions as prescribed for screw type cover must be observed. 3) Interior type. All dirt and cinders must be carefully removed from around the cover before the yoke is unscrewed. c) When the car is unloaded through a bottom outlet valve, the manhole cover must be adjusted as follows: 1) Screw type. The cover must be put in place, but not entirely screwed down, so that air may enter the tank through the vent holes in threaded flange of the cover. 2) Hinged and bolted type. A non-metallic block must be placed under one edge of the cover. 3) Interior type. The screw must be tightened up in the yoke so that the cover is brought up within one-half inch of the closed position. d) When unloading through the bottom outlet of a car equipped with an interior manhole type cover, and in each case where unloading is done through the manhole (unless a special cover with a safety vent opening and a tight connection for the discharge outlet is used), the manhole must be protected by asbestos or metal covers against the entrance of sparks or other sources of ignition of vapor, or by being covered and surrounded with wet burlap or similar cloth material. The burlap or other cloth must be kept damp by the replacement or the application of water as needed. e) Seals or other substances must not be thrown into the tank and the contents may not be spilled over the car or tank. f) The valve rod handle or control in the dome must be operated several times to see that outlet valve in the bottom of tank is on its seat before valve cap is removed. g) The valve cap, or the reducer when a large outlet is to be used, must be removed with a suitable wrench after the set screws are loosened and a pail must be placed in position to catch any liquid that may be in the outlet chamber. If the valve cap or reducer does not unscrew easily, it may be tapped lightly with a mallet or wooden block in an upward direction. If leakage shows upon starting the removal, the cap or reducer may not be entirely unscrewed. Sufficient threads must be left engaged and sufficient time allowed to permit controlled escape of any accumulation of liquid in the outlet chamber. If the leakage stops or the rate of leakage diminishes materially, the cap or reducer may be entirely removed. If the initial rate of leakage Department of Transportation 49 CFR Page 2 continues, further efforts must be made to seat the outlet valve (see paragraph (f) of this section). If this fails, the cap or reducer must be screwed up tight and the tank must be unloaded through the dome. If upon removal of the outlet cap the outlet chamber is found to be blocked with frozen liquid or any other matter, the cap must be replaced immediately and a careful examination must be made to determine whether the outlet casing has been cracked. If the obstruction is not frozen liquid, the car must be unloaded through the dome. If the obstruction is frozen liquid and no crack has been found in the outlet casting, the car may, if circumstances require it, be unloaded from the bottom by removing the cap and attaching unloading connections immediately. Before opening the valve inside the tank car, steam must be applied to the outside of the outlet casting or wrap casting with burlap or other rags and hot water must be applied to melt the frozen liquid. h) Unloading connections must be securely attached to unloading pipes on the dome or to the bottom discharge outlets before any discharge valves are opened. i) Tank cars may not be allowed to stand with unloading connections attached after unloading is completed. Throughout the entire period of unloading, and while car is connected to unloading device, the car must be attended by the unloader. j) If necessary to discontinue unloading a tank car for any reason, all unloading connections must be disconnected. All valves must first be tightly closed, and the closures of all other openings securely applied. k) As soon as a tank car is completed unloaded, all valves must be made tight, the unloading connections must be removed and all other closures made tight, except that heater coil inlet and outlet pipes must be left open for drainage. The manhole cover must be reapplied by the use of a bar or wrench, the outlet valve reducer and outlet valve cap replaced by the use of a wrench having a handle at least 0.9 m (3.0 feet) long, and the outlet valve cap plug, end plug, and all other closures of openings and of their prospective housings must be closed by the use of a suitable tool. 1) Railroad defect cards may not be removed. m) If oil or gasoline has been spilled on the ground around connections, it must be covered with fresh, dry sand or dirt. n) All tools and implements used in connection with unloading must be kept free of oil, dirt, and grit.

Containers of Class 1 (explosive), Class 3 (flammable liquid), Class 4 (flammable solid), Class 5 (oxidizing), Class 8 (corrosive), Glass 2 (gases) and Division 6. 1 (poisonous) materials, must be so braced as to prevent motion thereof relative to the vehicle while in transit. Containers having valves or other fittings must be so loaded that there will be the minimum likelihood of damage thereto during transportation. h) Precautions concerning containers in transit; fueling road units. Reasonable care should be taken to prevent undue rise in temperature of containers and their contents during transit. There must be no tampering with such container or the contents thereof nor any discharge of the contents of any container between point of origin and point of billed destination. Discharge of contents of any container, other than a cargo tank, must not be made prior to removal from the motor vehicle. Nothing contained in this paragraph shall be so construed as to prohibit the fueling of machinery or vehicles used in road construction or maintenance. i) Attendance requirements. 1 ) Loading. A cargo tank must be attended by a qualified person at all times when it is being loaded. The person who is responsible for loading the cargo tank is also responsible for ensuring that it is so attended. 2) Unloading. A motor carrier who transports hazardous materials by a cargo tank must ensure that the cargo tank is attended by a qualified person at all times during unloading. However, the carrier's obligation to ensure attendance during unloading ceases when: (i) The carrier's obligation for transporting the materials is fulfilled; (ii) The cargo tank has been placed upon the consignee's premises; and (iii) The motive power has been removed from the cargo tank and removed from the premises. 3) A person "attends" the loading or unloading of a cargo tank if, throughout the process, he is awake, has an unobstructed view of the cargo tank, and is within 7.62 meters (25 feet) of the cargo tank. 4) A person is "qualified" if he has been made aware of the nature of the hazardous material which is to be loaded or unloaded, he has been instructed on the procedures to be followed in emergencies, he is authorized to move the cargo tank, and he has the means to do so. 5) A delivery hose, when attached to the cargo tank, is considered part of the vehicle. j) Prohibited loading combinations. In any single driven motor vehicle or in any single unit of a combination of motor vehicles, hazardous materials shall not be loaded together if prohibited by loading and storage chart, 177.848. This section shall not be so construed as to forbid the carrying of materials essential to safe operation of motor vehicles. (See Motor Carrier Safety Regulations part 393 of this title.) k) [Reserved] 1) Use of cargo heaters when transporting certain hazardous material. Transportation includes loading, carrying, and unloading. 1) When transporting Class 1 (explosive) materials. A motor vehicle equipped with a cargo heater of any type may transport Class 1 (explosive) materials only if the cargo heater is rendered inoperable by: (i) Draining or removing the cargo heater fuel tank; and (ii) disconnecting the heater's power source. 2) When transporting certain flammable material — (i) Use of combustion cargo heaters. A motor vehicle equipped with a combustion cargo heater may be used to transport Class 3 ( flammable liquid) or Division 2. 1 (flammable gas) materials only if each of the following requirements are met: A) It is a catalytic heater. B) The heater's surface temperature cannot exceed 54 EC (130 EF) — either on a thermostatically controlled heater or on a heater without thermostatic control when the outside or ambient temperature is 16 EC (61 EP) or less. C) The heater is not ignited in a loaded vehicle. D) There is no flame, either on the catalyst or anywhere in the heater. E) The manufacturer has certified that the heater meets the requirements under paragraph (1)(2)(i) of this section by permanently marking the heater "MEETS DOT REQUIREMENTS FOR CATALYTIC HEATERS USED WITH FLAMMABLE LIQUID AND GAS." F) The heater is also marked "DO NOT LOAD INTO OR USE IN CARGO COMPARTMENTS CONTAINING FLAMMABLE LIQUID OR GAS IF FLAME IS VISIBLE ON CATALYST OR IN HEATER."

Unless the engine of the motor vehicle is to be used for the operation of a pump, no Class 3 (flammable liquid) material shall be loaded into, or on, or unloaded from any motor vehicle while the engine is running. b) Bonding and grounding containers other than cargo tanks prior to and during transfer of lading. For containers which are not in metallic contact with each other, either metallic bonds or ground conductors shall be provided for the neutralization of possible static charges prior to and during transfers of Class 3 (flammable liquid) materials between such containers. Such bonding shall be made by first connecting an electric conductor to the container to be filled and subsequently connecting the conductor to the container from which the liquid is to come, and not in any other order. To provide against Department of Transportation 49 CFR Page 5 ignition of vapors by discharge of static electricity, the latter connection shall be made at a point well removed from the opening from which the Class 3 (flammable liquid) material is to be discharged. c) Bonding and grounding cargo tanks before and during transfer of lading. 1) When a cargo tank is loaded through an open filling hole, one end of a bond wire shall be connected to the stationary system piping or integrally connected steel framing, and the other end to the shell of the cargo tank to provide a continuous electrical connection. (If bonding is to the framing, it is essential that piping and framing be electrically interconnected.) This connection must be made before any filling hole is opened, and must remain in place until after the last filling hole has been closed. Additional bond wires are not needed around All-Metal flexible or swivel joints, but are required for nonmetallic flexible connections in the stationary system piping. When a cargo tank is unloaded by a suction-piping system through an open filling hole of the cargo tank, electrical continuity shall be maintained from cargo tank to receiving tank. 2) When a cargo tank is loaded or unloaded through a vapor-tight (not open hole) top or bottom connection, so that there is no release of vapor at a point where a spark could occur, bonding or grounding is not required. Contact of the closed connection must be made before flow starts and must not be broken until after the flow is completed. 3) Bonding or grounding is not required when a cargo tank is unloaded through a nonvapor-tight connection into a stationary tank provided the metallic filling connection is maintained in contact with the filling hole. d) Manholes and valves closed. A person shall not drive a cargo tanks and motor carrier shall not require or permit a person to drive a tank motor vehicle containing a Class 3 (flammable liquid) material (regardless of quantity) unless: 1) All manhole closures on the cargo tank are closed and secured; and 2) All valves and other closures in liquid discharge systems are closed and free of leaks.

The first action should be the elimination of any additional spillage by pressing the emergency shutoff button, shutting off a pump or valve, placing a cap or a plastic or epoxy patch over the leak, putting a temporary plug in a puncture or tear, righting an overturned container, or other appropriate action. Spill response materials maintained at the facility will be used to contain and clean up spilled product. Place portable dike materials or erect berms with granular absorbent or earthen material along the leading edge of the spill to prevent spreading. Apply absorbent pads or granular absorbent to the spilled product for clean up. Using the Emergency Contact List for reference: 1 . Alert and notify on-site supervisory personnel. 2. If the spill exceeds the capabilities of on-site facility personnel (ie: spill spreads beyond the immediate spill area, enters surface water, requires special training or equipment, poses a danger of fire or explosion), immediately contact the local fire authority by calling 911 . 3. If the spill enters surface water, contact the National Response Center at (800) 424-8802. ❑ Materials recovered during cleanup must be placed in appropriate containers (such as DOT rated drums) or stockpiled using an impermeable liner and cover (such as polyethylene sheeting) to prevent cross-contamination with unexposed media prior to disposal.

In addition to the four main components, there will be auxiliary stationary equipment consisting of a thermal oxidizer, heat exchangers, chemical storage containers, solids dewatering platform with a filter press and associated tanks, and sludge storage tanks. The solids processing system will consist of multiple tanks varying in size from 50 bbls to 840 bbls within the processing building , individual containment areas, and a main secondary containment. The equipment will be placed within containment consisting of concreted dikes with a minimum capacity of 1 . 5 times the volume of the largest tank or compartment. Power for the system will be sourced from the local electric grid . The system is controlled by an automatic level instrumentation device with alarms and will be manned 24/7. The operational personnel are all highly trained and are certified by the State of Colorado. There will be one person per shift consisting of a Class D and a Class A water or wastewater operator as certified by the State of Colorado . Equipment: The truck offload area consists of two segments separated by the offload drain and four centrifugal pumps . Segment 1 is a concrete pad approximately 82-feet x 37 . 5-feet and segment 2 is a concrete pad approximately 82-feet x 60-feet. There are bollards surrounding the pumps at each truck lane in addition to protection by a structural column for the pump located at the washout platform . Fluid mixtures from tank bottoms are pumped via self-priming centrifugal pumps from the off-load bays into storage tanks within the main secondary containment "yard" . Drilling muds are offloaded using self- priming centrifugal pumps and enter the processing building for initial treatment. Tank Bottoms: After the tank bottoms have been offloaded the fluids pass through a one inch strainer before entering the pumps. The fluids are then pumped to the tank bottom storage tanks (4) inside the main secondary containment area which allow the system to compensate for the difference between a water system 's maximum pumping capacity and peak hour demand (equalization storage) . Fluids are pumped from the storage tanks through heat exchangers inside the process building thereby raising the temperature to 180 degrees Fahrenheit. The heated fluid exits the heat exchangers and enters the reaction tank where a coagulant is mechanically added to the reaction tank causing rapid mixing within the tank. As the fluid mixture is pumped to the centrifuge flocculant is mechanically added in-line between the reaction tank and the centrifuge holding tank. A filter press will be available to process slurry on an as needed basis to perform as a backup to the centrifuge method . Fluids are pumped from the centrifuge to the centrate/filtrate capture tanks (3) to undergo oil and water separation . After separation the oil from the centrate/filtrate tanks is pumped to the oil tanks (6) within the main containment "yard" and water (brine) is pumped into the water tanks (4) also located inside the yard . Oil from the tanks will be removed by vacuum trucks on a regular basis. Water from the brine tanks will be pumped daily to the existing C6 water recycle facility via an underground PVC 6" line . Drilling Muds: After the drilling muds have been offloaded at the offload bays the fluids will pass through a one inch strainer before entering the pumps. The fluids are pumped into linear shale shakers located just outside of the offload area which screen and reduce the particles within the drilling muds to less than 500 micron . Solids from the shakers will be held in a roll-off dumpster located next to the shakers and finally transported directly to a landfill . A sump is located directly under the shakers to catch fluid as it passes through the screens. A pump removes drilling mud fluids out of the sump and sends it to the drilling mud tanks (4) within the main containment area . From the drilling mud tanks the fluid is pumped to the drilling muds reaction tank inside the processing building . Coagulant is added via an automated system to the reaction tank causing rapid mixing . As the fluid mixture is pumped to the centrifuge flocculant is added in-line mechanically between the reaction tank and the centrifuge holding tank. A filter press will be available to process slurry on an as needed basis to perform as a backup to the centrifuge method . Fluids are pumped from the centrifuge to the centrate/filtrate capture tanks (3) to undergo further separation whereby the water is then pumped out to the water tanks (4) in the main containment area . The piping connecting the oil tanks and all of the piping runs downstream of the heat exchangers are constructed of steel . All other associated piping is constructed of PVC or flex hoses for the offload pumps and shale shakers inlets . Solids Processing : Solids will be removed from incoming waste in the centrifuges and transferred to the solids temporary staging shed by means of a conveyor belt system . Incoming waste may also be processed through a filter press to remove solids . The filter press is intended to be used as a backup (standby) system , with the centrifuge acting as the primary dewatering system . Solids from the decanter centrifuge will be transferred to the solids temporary staging shed . The fluids will continue to move into the centrate/filtrate tanks where oil and water separation occurs. Oil will be pumped to six oil tanks in the main containment area where it is eventually removed by vacuum trucks on a regular basis and sold offsite. Operations and Control System : The entire water recycling facility is controlled by an Allen Bradley PLC system with HMI operator interface . Multiple data points are recorded . All flows, tank levels and chemical drum and tank weights are monitored . An immediate loss in drum or tank weight would initiate an alarm . All pH values and chemical feeds are automated . Each 12 hour shift is manned by 2 operators with additional manpower spread across several shifts to assist with dewatering . The main operators are State of Colorado certified water, wastewater, or both , operators. Each shift is operated with one A class operator and one D class or better certified operator. These operators have received significant training in our system operation at our facility in Denver. Chemicals : All the chemicals utilized in the treatment of this water are National Science Foundation approved chemistries for the treatment of potable water. Below is a list of the main chemicals used but is subject to change as required to meet treatment goals; 35% Hydrochloric acid solution 40% Ferric Chloride Chemical Storage Ferric Chloride Tank — 9996 gal Hydrochloric Acid Tank — 9996 gal Liquid Volumes Process Buildings Reaction Tanks (2 ) — 6300 gal/each Centrate/Filtrate Tanks (3) — 16800 gal/each Filter Press — ( 1 ) — 598 gal Hot Brine Tank — ( 1 ) — 5000 gal Reverse Osmosis Tank — ( 1 ) — 5000 gal Hello
