C6 Solids Processing Facility Process Description Tank Bottoms: Tank bottoms are offloaded at the offload bays using self-priming centrifugal pumps. The fluids pass through a 2" trash rack before entering the pumps. Tank bottoms are then pumped through a strainer pot (3/8" perforations) to the tank bottom tanks, in the concrete containment area, which provide equalization storage volume. From the tank bottom tanks, the fluid is then pumped into the main process building. In this building, the fluid passes through a heat exchanger and into the tank bottom reaction tank. The fluid is heated to 180 degrees Fahrenheit in the heat exchangers. Coagulant is added in the reaction tank and rapid mixing occurs. Then, the tank bottoms are pumped to the decanter centrifuge. Polymer (flocculant aid) is dosed in line between the reaction tank and the centrifuge. Centrate from the tank bottoms goes to the tank bottom Centrate/Filtrate Capture tank under the centrifuge platform. It is then pumped to the tank bottom Centrate/Filtrate tanks (also in the main process building) for oil/water separation. Oil from the tank bottom Centrate/Filtrate tanks is pumped to the Oil tanks in the yard. Water (brine) from the tank bottom Centrate/Filtrate tanks is pumped to the water tanks in the yard. Oil from collection is sold and transported offsite in oil tanker trucks. Drilling Muds: Drilling muds are offloaded at the offload bays using self-priming centrifugal pumps. The fluids pass through a 2" trash rack before entering the pumps. Drilling muds are then pumped to a linear shale shakers. The shakers screen the drilling muds down to 500 micron. A sump under the shakers catches fluids that pass through the screens. A pump draws drilling muds out of this sump and sends it to the drilling mud tanks. From the drilling mud tanks, the fluid is then pumped into the main process building to the drilling mud reaction tank. Coagulant is added in the reaction tank and rapid mixing occurs. Then the drilling muds are pumped to the centrifuge. Polymer (flocculant aid) is dosed in line between the reaction tank and the centrifuge. Centrate from the drilling mud goes to the drilling mud Centrate/Filtrate Capture tank under the centrifuge platform. It is then pumped back outside to the water tanks in the yard. Solids: Solids from the centrifuge and filter press fall onto a covered conveyor belt below the centrifuge platform. The conveyor belt moves the solids into covered containers in the solids holding building next to the main process building. The solids holding building has one open side for front loader access. Front loaders are used to move roll off dumpsters for transport to the local landfill. Concrete housekeeping pads with curbs are provided under the entire length of the conveyor belt. The pads are sloped to sumps, which are equipped with sump pumps that send the spillage/drainage back to the front of the process. __ie.—Nag% M3C0N-1 OP ID: MH AC� 07/19 CORP CERTIFICATE OF LIABILITY INSURANCE DATE DIYYYY) 07119!13 THIS CERTIFICATE IS ISSUED AS A MATTER OF INFORMATION ONLY AND CONFERS NO RIGHTS UPON THE CERTIFICATE HOLDER.

SECTION 2 SWMP DESIGN DRAWINGS Please see attached erosion control plan for the site. SECTION 3 STORMWATER MANAGEMENT CONTROLS a. SWMP Administrator and Important Contacts SWMP Administrator (Contractor) Nick Valencia 913-424-4073 b. BMPs for Stormwater Pollution Prevention 1. Vegetative Buffer:The existing vegetation will not be disturbed whenever possible and be used as a buffer(min of 70') between the row to the east and south and the limits of the disturbance area. 2. Silt Fence: Silt fence will be placed around the down gradient side of the project boundaries for sediment control. 3. Vehicle Tracking: A vehicle tracking pad will be utilized at the access/exit points of the site in order to minimize off-site sediment tracking. 4. Please see drawings for location of site specific BMP's Section 4 Spill Response— Cleanup and Removal Procedures • Upon detection of any spill, the first action to be taken is to ensure personal safety. All possible ignition sources, including running engines, electrical equipment(including cellular telephones, etc.), or other hazards will be immediately turned off or removed from the area.The extent of the spill and the nature of the spilled material will be evaluated to determine if remedial actions could result in any health hazards, escalation of the spill, or further damage that would intensify the problem. If such conditions exist, a designated employee will oversee the area of the spill and the construction SWMP Administrator will be notified immediately. • The source of the spill will be identified and if possible the flow of pollutants stopped if it can be done safely. However, no one should attend to the source or begin cleanup of the spill until ALL emergency priorities (fire, injuries, etc.) have been addressed. Small Spills Small spills (usually<5 gallons) consist of minor quantities of gasoline, oil, anti-freeze, or other materials that can be cleaned up by a single employee using readily available materials. The following procedures should be used for clean-up of small spills: a. Ensure personal safety, evaluate the spill, and if possible, stop the flow of pollutants. b. Contain the spread of the spill using absorbents, portable berms, sandbags, or other available BMPs. c. Spread absorbent materials on the area to soak up as much of the liquid as possible and to minimize infiltration into the soil. d. Once the liquids have been absorbed, remove all absorbents from the spill and place the materials in a suitable storage container. On paved areas,wipe any remaining liquids from the surface and place the materials in a storage container. Do not spray or wash down the area using water. For open soil areas, excavate any contaminated soil as soon as possible and place the soil in a suitable storage container.All materials will then be transported off-site for disposal. e. If immediate transfer and storage of the contaminated soil is not practical, excavate and place the contaminated soil on a double thickness sheet of 3-mil or higher polyethylene film. In addition, a small berm should be formed around the outer edges of the soil stockpile, underneath the polyethylene film;to ensure that contaminants are not washed from the site during precipitation events and that materials do not seep through the berm. f. Record all significant facts and information about the spill, including the following: • Type of pollutant • Location • Apparent source • Estimated volume • Time of discovery • Actions taken to clean up spill g. Notify the SWMP Administrator of the spill and provide the information from Item Medium to Large Spills Medium to large spills consist of larger quantities of materials (usually >5—25 gallons) that are used on site that cannot be controlled by a single employee. Generally, a number of facility personnel will be needed to control the spill and a response may require the suspension of other facility activities.The following procedure shall be used for the cleanup of medium to large spills: a. Ensure personal safety, evaluate the spill, and if possible, stop the flow of pollutants. b. Immediately dispatch a front-end loader or similar equipment to the spill and construct a berm or berms down gradient of the spill to minimize the spread of potential pollutants. On paved surfaces, portable berms, sandbags, booms, or other measures will be used to control the lateral spread of the pollutants c. When the spread of the spill has been laterally contained, contact the SWMP Administrator or designated facility employee and provide them information on the location, type, and amount of spilled material, and a briefing on the extent of the spread and measures undertaken to contain the contaminants. d. Depending on the nature of the spill, mobilize additional resources as needed to contain the contaminants. e. Cleanup will commence when the lateral spread has been contained and the notification to the SWMP Administrator has been made. f. Freestanding liquid will be bailed or pumped into 55-gallon storage drums, steel tanks, or other suitable storage containers. When all the liquid has been removed from the pavement or soil layer, absorbents will be applied to the surface and transferred to the storage containers when they have soaked up as much of the spill as possible. g. On paved surfaces,the remaining contaminants will be removed to the extent possible, with rags, sweeping, or similar measures. The area of the spill will not be sprayed or washed down using water. Any contaminant soaked materials will be placed into the storage containers with the other absorbents. h. The remaining contaminated soils will be excavated and loaded into a dump truck(s) for disposal off-site at a designated facility. If transport off-site is not immediately available,the remaining soils will be stockpiled on a double thickness sheet of 3-mil or higher polyethylene film. In addition, a small berm will be formed around the outer edges of the soil stockpile, underneath the polyethylene film,to ensure that contaminants are not washed from the site during precipitation and do not seep through the berm. Record all significant facts and information about the spill, including the following: • Type of pollutant • Location • Apparent source • Estimated volume • Time of discovery • Actions taken to clean up spill j. Provide the SWMP Administrator(or designated employee)with the information from Item #6. Notifications Notification to the Colorado Department of Public Health & Environment (CDPHE) is required if there is any release or suspected release of any substance, including oil or other substances that spill into or threaten State waters. Unless otherwise noted, notifications are to be made by the SWMP Administrator and only after emergency responses related to the release have been implemented.This will prevent misinformation and assures that notifications are properly conducted. The notification requirements are as follows: 1.

Platteville is approximately eight miles to the west. The aerial photo shows the location. In this area, WCR-39 is a two-lane paved collector roadway that carries - 4 - - -t rr approximately 1 ,000 vehicles per day I' ' ' - according to the Weld County 2035 Transportation Plan. It is 24 feet wide and in good condition per the plan. The plan forecasts an increase to ... , :^ approximately 3,400 vpd by 20351 . The daily capacity is 4,600 vpd2. The access 39 to the site features a 175 foot right turn -o ' The plan actually forecasts 310 vpd by 2035. This is obviously in error and we have assumed a 3.4 growth rate consistent with the plan's overall growth rates in this area. 2 This is a planning-level traffic capacity. Actual capacity is determined from a peak-hour analysis prescribed in the HCM 2010. ALDRIDGE TRANSPORTATION CONSULTANTS, LLC Page 2 of 2 deceleration lane and a 125 foot left turn deceleration lane. The water disposal facility will employ 15 persons per 24 hour period. This is an increase of five employees. With the expansion, it will serve approximately a maximum of 180 trucks per day spread out over a 24-hour period. The average is less than 150 trucks per day. The average number of trucks will not exceed the estimated daily capacity of 4,600 vpd. The peak hour capacity with approximately 10-20 per hour trucks is not exceeded and the access will unquestionably operate at LOS A in the near-term and LOS B in 2035 with the projected volumes. Based on this analysis, the present roadway surface, geometric design, and traffic control will adequately handle, without improvements, the truck traffic generated by the expansion of the water disposal facility.

Aldrid:e, PE, PTOE, AICP Principal JMWA/me C 6 SITE WASTE MANAGEMENT PLAN N LG WATER SOLUTIONS DJ, LLC Scope: This Waste Management Plan has been prepared to provide onsite operations personnel at the C6 site with the information necessary to properly identify, manage and dispose of wastes, and to ensure the safety and protection of employees, the public and the environment. The objective of this plan is to ensure waste generated at the site is managed according to all Local, Colorado and Federal regulations. Further, the plan will define operational chemicals used or stored on site requiring specific disposal pathways. Chemicals Stored On Site: The following materials will be stored at the site to support operations and have specific disposal requirements. The quantities given are the maximum amount to be stored on site at a single time. The coagulants and polymers listed below are all of the chemicals that may be used at one time or another for sludge treatment on the site. Only two or three of these are likely to be stored on site at any given time. NOTE:The oil collected as part of the skimming process is captured in three 400 BBL separation tanks in the main process building, and then stored in six 400 BBL steel tanks in the tank farm, and is considered production oil that will be trucked out for sales. This oil is not considered waste and is not listed in this plan. Chemicals Description Quantity Diesel Fuel Distillate fuels suitable for use in high and medium speed internal 50 Gal. combustion engines of the compression ignition type Emulsion Breaker Clear to Slightly Hazy Light 30 Gal. Amber to Dark Amber liquid with pungent odor Crude Oil (petroleum) Naturally occurring,yellow-to-black liquid found in geologic 90 BBL's formations beneath the Earth's surface, which is commonly refined into various types of fuels Unleaded Gasoline Light straw to red clear liquid with characteristic strong odor of 15 Gal. gasoline Chevron Way Oil Vistac Brown liquid with Petroleum odor 20 Gal.

Off-white 1,375 Gal translucent liquid with hydrocarbon odor. NOTE:All chemicals listed above will have Material Safety Data Sheets on-site. Projected Waste Streams and Volume: Waste Stream Waste Constituents Volume Disposal contact Sale Oil Crude oil 1-3 Loads per day NGL Crude Oil Transportation Solid Wastes Dewatered sludge (sand, 200-550 cuyds/day, Waste Management - silt,trace oil, coagulants, removed in 20 cubic Buffalo Ridge Landfill polymers) yard dumpsters Dumpsters Trash 4-6 Cubic yard Waste Management dumpsters, removed weekly NOTE:The primary waste stream generated will be dewatered sludge, as the primary purpose of the facility is dewatering/treatment of oil and gas tank bottoms and drilling muds. Any wastes that may be generated during the construction of this site will be temporarily stored in covered containers and will be removed from the site for proper disposal at a permitted facility. Spill Prevention and Response: Activities related to solids processing facilities require storage of hazardous and nonhazardous products and wastes. All efforts will be made to prevent spills of any amount of these products. The scope of this plan is intended to cover activities related to associated facilities. The following procedures will be followed to help avoid spills and minimize the impact of spills that accidentally occur: C Bulk quantities of any chemical will be stored in above ground tanks, which will be diked or be of double wall secondary containment design, or smaller containers. Secondary containment will also be provided for loading/unloading areas. No underground tanks will be used. A Safety Data Sheet (SDS) for each hazardous material will be located on site. Fuel will be stored within secondary containment and as much as practical all equipment will be refueled there. Any equipment that must be refueled in the field will be fueled from tanks carried to the work area. Lesser quantities of chemicals (i.e., cleaning supplies, lubricants) may be stored at the work area as necessary to service equipment provided that this storage does not conflict with other parts of this plan. I_ All chemical storage areas will be located at least 200 feet from active private water wells, and at least 400 feet from municipal water wells. Equipment servicing, lubricating, and refueling will also be in accordance with these requirements whenever possible. I_ Use of hazardous materials for vehicle maintenance will follow the same requirements mentioned above for equipment refueling. Impervious or sorbent materials will be placed under the work area before the work begins. Additional sorbent materials will also be readily available. 2 11 Waste materials created during maintenance (i.e., used oil) will be collected for proper disposal. L The work site for which these chemicals are used will be inspected after the maintenance work is complete to ensure that all hazardous materials are properly contained. All waste material, including partially used or empty containers, discarded parts, dirty rags, and used sorbent material, as well as discarded hazardous materials containers (i.e., oil cans, grease tubes) will be collected and placed in open-top drums for proper disposal. - All motor fuel, lube oil, chemicals, and other polluting substances will be tightly sealed and clearly labeled during transportation and storage. Runoff resulting from facility equipment washing operations will not be permitted to directly enter any water body or wetland area. Construction equipment, vehicles, materials, hazardous materials, chemicals, fuels, lubricating oils, and petroleum products will be parked, stored, or serviced 100 feet from all water bodies and wetlands when not in use and when possible. Any materials, hazardous materials, chemicals, fuels, lubricating oils, and petroleum products that must be used within 100 feet of a water body or wetland to support the work will only be used within the secondary containment protection and will be stored within temporary secondary containment during work hours. No materials, hazardous materials, chemicals, fuels, lubricating oils, or petroleum products that are not contained within equipment will be stored within 100 feet of a water body or wetland. All other sections of this plan will be followed for spill prevention and mitigation and cleanup methods. All equipment will be inspected daily for leaks prior to beginning operations. Steps will be taken to repair leaks or remove the equipment from service, if necessary. E All containers containing any hazardous material (i.e. chemicals, lubricants, oils) will be neatly labeled. - The height of stacked containers will be limited and containers will be stacked carefully to provide stability to avoid spills. Clean up procedures and materials will be readily available and clearly posted at work areas. Pollution Incident Response: In the event of a spill the following will occur: E The source will be immediately stopped. - The spill will be contained by placing sorbent booms or constructing dikes. - The spill will be collected with sorbent materials, skimmed off water surfaces with booms, and/or the contaminated soil will be excavated; and the waste materials will be properly disposed in accordance with NGL's internal policies. E Document the spill and its clean-up procedures whether reporting is required or not. At a minimum document the following: o Nature of spill o Quantity of spill o Date/time spill occurred: Agency notification if necessary o Clean-up procedures used o Daily monitoring (7 days) after clean-up o Photographs o Interview(s) with any witnesses of the event 3 ▪ The affected areas will be restored as closely as possible to their previous condition. Spills of oil or petroleum products should be reported immediately to the Site Manager. Environmental support staff will determine the reporting requirements and contact the appropriate State and Federal environmental agencies for notification requirements. If the Site Manager cannot be contacted, then the Site Supervisor should make the necessary notifications. A reportable release is a quantity or an unknown quantity of regulated substance released to or posing an immediate threat to surface water, groundwater, bedrock, soil or sediment. The term does not include the following, provided the owner or operator has control over the release, the release is completely contained, and within 24 hours of the release, the total volume of the release is recovered or removed in the corrective action: o A release to the interstitial space of a double-walled aboveground or underground storage tank. o A release of less than 25 gallons to a containment area, structure or facility around an aboveground storage tank. o A release of less than five gallons to a synthetic surface, such as asphalt or concrete, which prevents migration of the regulated substance to surface water, groundwater, bedrock, soil or sediment; and a release of less than one-gallon to surface soils. ▪ Some spills will need to be reported to the Division of Water Quality immediately including the following: o Over 25 gallons of petroleum. o Over 5 CCs of mercury. C A release of any chemical, oil, petroleum product which entered waters of the State of Colorado (which include surface water, groundwater, dry gullies or storm sewers leading to surface water). C Any spill or release of raw sewage. ▪ If any of the above criteria is met or exceeded, the Colorado Department of Public Health and Environment (CDPHE), Local Emergency Planning committee, downstream users and other agencies (MS4s) will be notified. The CDPHE will be notified by telephone within 24 hours. In addition, written notification describing the spill and the cleanup procedures used will be sent to the agencies 5 days following the spill. If a spill does not meet the above criteria, reporting is not mandatory. CDPHE 24-hour environmental emergency spill reporting line is 1-877-518-5608.

The Chloride product that will most likely be used will be Magnesium Chloride. ▪ The Chloride product will be applied as needed throughout the entire construction/site work process as the road surface changes, due to traffic or weather conditions. J Application of water& chemicals will be done with a 1200 gallon tank truck with a spray type applicator. Parking Area ▪ The primary parking area that is closest to the activities area will be constructed of the same material as the site access.This will provide for any handicap parking needs as well as a dust abatement plan for the heaviest traveled parking area. ❑ The overflow parking area will be moistened with non-potable water, not a chemical chloride product, to prevent any potential vegetation damage. ❑ The isles of the overflow parking area will be the largest concern for dust &they will be monitored throughout the day. Water will be applied as needed to this parking area. ❑ Application of water will be done with a 1200 gallon tank truck with a spray type applicator. Activities Area ❑ The activities area will be monitored daily&throughout the day for dust control. ❑ As surface may become loosened with traffic; non-potable water will be applied to the area as needed to lessen the effects of heavy foot traffic. ❑ Application of non-potable water will be done by either a 1200 gallon tank truck with a spray type applicator or a 30 gallon sprayer mounted on an All-Terrain Vehicle.

Box 758 Greeley CO 80632 RE: Drainage letter for High Sierra's C6 facility at 13159 CR 39 Platteville CO 80651 Dear Ms. Petrik: This letter addresses the Water Quality Capture Volume (WQCV) requirements and existing and proposed drainage ways on the site The storm-water historically enters the site from the north-west and drains across the site to the south east. The proposed plan will collect on site flows and direct them around the proposed improvements to the water quality pond in the south east corner of the site. When the water quality pond reaches capacity at elevation 4922 storm-water will flow to the east as sheet flow. Storm water will travel approximately 70 feet east on the lot to further dissipate flows before they travel into the ditch along WCR 39. The proposed conditions imperviousness (including all of the existing improvements)is 7.4 which is less than the 10 which would require the site to have a detention pond.

Water quality sampling activities for the C6 facility are performed on a quarterly basis. The most recent sampling activities were performed on September 16, 2014. Water quality samples obtained from the groundwater monitoring wells are analyzed for benzene, toluene, ethylbenzene, and xylenes (BTEX), total dissolved solids (TDS), dissolved metals, and chlorides. These compounds are commonly associated with the oil field production water and associated sediment which is disposed of at the NGL facility. The water quality monitoring program provides baseline background groundwater quality data, which will facilitate early detection of an unknown release of production water related to facility operations. Furthermore, depth to groundwater is measured in each monitoring well and the groundwater elevation, flow direction and hydraulic gradient are calculated using surveyed well elevations in order to monitor groundwater flow trends. A total of four groundwater monitoring wells (MW-3, MW-4, MW-5, and MW-6) have been installed for facility monitoring purposes. An additional monitoring well has been proposed downgradient of the solids processing tank farm. See Figure 2 for monitoring well locations and site condition details. The monitoring wells were installed to a depth of approximately 30 to 53 feet below ground surface (bgs). The wells were constructed with approximately 25 to 35 feet of 2-inch diameter, 10-slot PVC screen and approximately 10 to 23 feet of solid PVC riser based on the depth to groundwater in each well location. 10/20 silica sand surrounds the screened portion of the wells to a depth of 2 feet above the well screen, at which point the well bore is sealed with hydrated bentonite to the surface. The wells are finished with either a flush mounted steel manway or a 3 foot aluminum locking stick up mount. Based on information collected during well installation activities, the subsurface lithology generally consists of alternating layers of sand and silty sand to sandy/silty clay and clay from the surface to approximately 20 to 41 feet bgs. Starting at approximately 20 to 41 feet bgs, weathered blocky claystone with secondary calcareous and iron oxide mineralization was encountered to the total depth of the borings. Semi-annual groundwater quality monitoring has been ongoing since November, 2007, and has recently been adjusted to a quarterly monitoring schedule per the suggestion of the Weld County Department of Public Health and Environment. Historic groundwater monitoring data indicates groundwater depths across the site vary from approximately 14 to 29 feet below the top of the surveyed well casings. 1301 Academy Court Fort Collins, CO 80524 T 800-288-2657 F 970-493-7986 www.cgrs.com Site Groundwater Monitoring Plan NGL Water Solutions; C6 Disposal Facility 13159 Weld County Road 39 Platteville, Weld County, Colorado S1/2, E1/4, Sec. 30, T3N, R65W Furthermore, data indicates a consistent groundwater flow direction to the southeast towards monitoring wells MW-5 and MW-3 at a calculated hydraulic gradient of 0.05 ft/ft.

Using this procedure, a 2-inch O.D. split-spoon sampler will be driven into the soil by a 140-pound weight falling 30 inches. After an initial set of 6 inches, the number of blows required to drive the sample an additional 12 inches, known as the penetration resistance (N value), will be recorded. The N value is an index of the relative density of cohesionless soils and the consistency of cohesive soils. Soil Classification/Characterization As samples are obtained in the field, they will be visually inspected and classified in accordance with ASTM:D 1488-84. Representative portions of the samples will then be retained for further examination and for verification of the various strata, the N value, water level data, and pertinent information regarding the method of maintaining and advancing the boring will be provided. Charts illustrating the soil classification procedure, descriptive terminology and symbols used on the logs will be provided. As samples are collected they will be examined for evidence of petroleum hydrocarbons using visual appearance, odor, and by screening with portable photoionization equipment. Decontamination To avoid potential transport of contaminated materials to the project site, all drilling equipment and down- hole tools will be steam cleaned prior to mobilization. To prevent cross contamination between soil borings or monitoring wells all down-hole equipment will also be steam cleaned and rinsed with water between soil borings. Monitoring Well Construction New Monitoring wells will be installed utilizing the following general construction criteria: ❑ borehole diameter: minimum 2.0 inches push probe / 6.25 inches conventional boring ❑ well diameter: 1 inch for push probe / 2 inches for conventional boring ❑ estimated depth: ≥ 5 feet below static groundwater table -a- CGRS, INC. NGL Water Solutions C6 Facility ❑ casing material: schedule 40, flush thread PVC ❑ well screen: 1 inch I.D. for push probe / 2 inch I.D. for conventional boring, # 0.01 slot PVC ❑ estimated screened interval: 10 feet above and 10 feet below the groundwater table (may be adjusted based on total depth and water table position) ❑ annular pack: 10-20 silica sand ❑ protective casing: 4" aluminum above grade mount, locking cap h annular seal : cement grout and bentonite pellets. Groundwater Sampling All borings where groundwater is encountered will be sampled from the suspected cleanest to the most contaminated according to the protocols listed below. All pertinent information will be recorded on a sampling information form. Field Protocol Step 1 - Measure water level. Step 2 - A dedicated polyethylene bailer will be used to develop each boring. Three bore volumes will be evacuated from each boring prior to sampling. Step 3 - Collect water samples. Water samples will be collected using a polyethylene bailer. Step 4 - Store samples in a cooler on ice for transport to the laboratory. Follow all documentation and chain-of-custody procedures. Step 5 - Clean equipment. Water level measurement equipment will be cleaned with ethanol followed by a deionized water rinse. Upon completion of soil or groundwater sampling, a chain of custody log will be initiated. A copy of the chain of custody will be returned to the project manager. Chemical Analysis An approved contract laboratory will provide stationary laboratory analysis. The following analyses will be performed: Soil Analyses Chemical Parameters Method Used Benzene/Toluene/Ethylbenzene/Total Xylenes EPA - 8260 Total Recoverable Petroleum Hydrocarbons EPA - 418. 1 -b- CGRS, INC. NGL Water Solutions C6 Facility Total Metals EPA 6010O & 7471B Water Analyses Benzene/Toluene/Ethylbenzene/Total Xylenes (BTEX) EPA - 8260 B Total Dissolved Solids (TDS) EPA - 160. 1 Chloride EPA - 300. 1 Dissolved Metals EPA-3005A Groundwater Trend Analyses Groundwater concentrations are measured in site monitoring wells on a quarterly basis. Upon receiving groundwater analytical data from the laboratory the data is inserted into an historic groundwater analytical data table. Chlorides and TDS concentrations will be evaluated to ensure that the current concentrations in each well do not exceed 1 .25 times the average background conditions. If results indicate that this threshold is exceeded, then further analyses or investigation will be conducted. Any BTEX constituents above the Colorado Oil and Gas Conservation Commission (COGCC) maximum allowable concentrations (MACs) discovered in a monitoring well water quality sample will be reanalyzed at the laboratory. If the laboratory re-analyses confirms the presence of a BTEX constituent above the MACs then the well will be resampled. The presence of BTEX above MACs will prompt a complete evaluation of site operations since the last quarterly sampling event, and prompt further subsurface investigation if warranted. Groundwater Elevation Measurements The following outlines our standard groundwater quality sampling methodology. Before purging any of the soil test borings or monitoring wells, water level measurements must be taken. Measuring Point Establish the measuring point for the well. The measuring point is marked on the north side of the top of the temporary monitoring well riser. The top of the riser is normally a 2-inch schedule 40 PVC casing inside a locked protective casing. The measuring point should be described on the groundwater sample collection record. -c- CGRS, INC. NGL Water Solutions C6 Facility Access After unlocking or opening a monitoring well, the first task will be to obtain a water level measurement. Water level measurements will be made using an electronic water level indicator. Depth to water and total depth of the well will be measured for calculation of purge volume. Measurement To obtain a water level measurement, lower a decontaminated electronic water level probe into the monitoring well. Care must be taken to assure that the electronic probe hangs freely in the monitoring well and is not adhering to the well casing. The electronic probe will be lowered into the well until the audible sound of the unit is detected and the light on the electronic sounder illuminates. At this time, the precise measurement should be determined by repeatedly raising and lowering the probe to obtain an exact measurement. The water level measurement is then entered on the groundwater sampling collection record sheet or groundwater level data sheet to the nearest 0.01 feet. Decontamination The electronic probe shall be decontaminated immediately after use by wiping with isopropyl alcohol- soaked paper towels. Always proceed in order from the suspected cleanest well or soil test boring to the suspected most contaminated one. Purge Volume Computation All soil test borings and temporary monitoring wells will be purged prior to sample collection. Depending upon the rate of recovery, three to five volumes of groundwater present in a well or borehole shall be withdrawn prior to sample collection. If a well or bore hole bails dry, the well or bore hole should be allowed to recharge and a sample taken as soon as there is sufficient volume for the intended analysis. The volume of water present in each well or bore hole shall be computed using the two measurable variables, length of water column in soil boring or monitoring well depth and diameter. Purging and Sample Collection Procedures Bailing Obtain a laboratory decontaminated disposable bailer and a spool of nylon rope or equivalent bailer cord. Tie a bowline knot or equivalent through the bailer loop. Test the knot for adequacy by creating tension between the line and the bailer. Tie again if needed. New rope will be used for every sample or purge event. New clean latex gloves will be used when touching the rope or bailer. -d- CGRS, INC. NGL Water Solutions C6 Facility O Spread a clean plastic sheet near the base of the well. The plastic sheet should be of sufficient size to prevent bailer or bailer rope from contacting the ground surface. Place the bailer inside the well to verify that an adequate annulus is present between the bailer and the well casing to allow free movement of the bailer. I Lower the bailer carefully into the well casing to remove the sample from the top of the water column, taking care not to agitate the water in the well. ❑ Pour the bailed groundwater into a bucket. Once the bucket is full, transfer the water to a barrel and contain on-site. Li Raise the bailer by grasping a section of cord, using each hand alternately. This bailer lift method will assure that the bailer cord will not come into contact with the ground or other potentially contaminated surfaces. Sampling O Instructions for obtaining samples for parameters are reviewed with the laboratory coordinator to insure that proper preservation and filtering requirements are met. ❑ Appropriate sample containers will be obtained from the contract laboratory for the Hazardous Substance List (HSL) for organics. After samples are collected, they will be put on ice in coolers (4°C). Care will be taken to prevent breakage during transportation or shipment. 0 Samples collected by bailing will be poured directly into sample containers from bailers. The sample should be poured slowly to minimize air entrapment into the sample bottle. During collection, bailers will not be allowed to contact the sample containers. ❑ Upon completion of sampling a chain-of-custody log will be initiated. Chain-of-custody records will include the following information: project name and number, shipped by, shipped sampling point, location, field ID number, date, time, sample type, number of containers, analysis required and sampler's signature. The samples and chain-of-custody will be delivered to the laboratory. Upon arrival at the laboratory the appropriate laboratory personnel will check in the samples. Laboratory identification numbers will be noted on the chain-of-custody record. Upon completion of the laboratory analysis, the completed chain-of-custody record will be returned to the project manager. Field Cleaning Procedures For all equipment to be reused in the field, the following cleaning procedures must be followed: -e- CGRS, INC. NGL Water Solutions C6 Facility ❑ Disassemble the equipment to the extent practical. ❑ Wash the equipment with distilled water and laboratory-grade detergent. ❑ Rinse with distilled water until all detergent is removed. ❑ Rinse the equipment with isopropyl or methanol, making sure all surfaces, inside and out, are rinsed. ❑ Triple rinse the equipment with distilled water. Laboratory Selection The project manager should consider the following factors when selecting a laboratory: ❑ Capabilities (facilities, personnel, instrumentation), including: H Participation in interlaboratory studies (e.g., EPA or other Federal or State agency sponsored analytical programs); ❑ Certifications (e.g., Federal or State); ❑ References (e.g. other clients); and ❑ Experience (UST, RCRA and other environmentally related projects). El Service: Li Turnaround time; and ❑ Technical input (e.g., recommendations on analytical procedures). The project manager is encouraged to gather pertinent laboratory-selection information prior to extensively defining analytical requirements under the project. A request may be made to a laboratory to provide a qualifications package that should address the points listed above. Once the project manager has reviewed the various laboratory qualifications, further specific discussions with the laboratory or laboratories should take place. In addition, more than one laboratory should be considered. For large-scale investigations, selection of one laboratory as a primary candidate and one or two laboratories as fall-back candidates should be considered. The quality of the laboratory service provided is dependent on various factors. The project manager should be able to control the quality of the information (e.g., samples) provided to the laboratory. It is extremely important that the project manager communicate to the laboratory all the requirements relevant to the project. This includes the number of samples and their matrices, sampling schedule, parameters and constituents of interest, required analytical methodologies, detection limits, holding times, deliverables, level of QA/QC, and required turnaround of analytical results. -f- CGRS, INC. NGL Water Solutions C6 Facility Field and Laboratory Quality Control General Quality control checks are performed to ensure that the data collected is representative and valid data. Quality control checks are the mechanisms whereby the components of QA objectives ore monitored. Examples of items to be considered are as follows: 1. Field Activities: 0 Use of standardized checklists and field notebooks; 0 Verification of checklist information by an independent person; 0 Strict adherence to chain-of-custody procedures; ❑ Calibration of field devices; ❑ Collection of replicate samples where applicable; and u Submission of field blanks, where appropriate. 2. Analytical Activities: ❑ Method blanks; 0 Laboratory control samples: O Calibration check samples; O replicate samples; ❑ Matrix-spiked samples; ❑ "Blind" quality control samplers; ❑ Control charts; ❑ Surrogate samples; ❑ Zero and span gases; and Reagent quality control checks. Management of Waste Material During the advancement of soil borings, decontamination of field equipment and development of soil borings or temporary monitoring wells, waste materials will be generated. This section addresses both the management of solid waste (soils) and the liquid wastes generated. Soil generated during remedial activities will be containerized in 55-gallon drums or stockpiled on an impermeable membrane and covered with plastic, which ever is most appropriate. The waste characteristics of the soil will be determined by appropriate analytical methods and the soil disposed of in accordance with state and federal regulations. Water generated during field activities will be containerized in storage vessels, -g- CGRS, INC. NGL Water Solutions C6 Facility which are compatible with the suspected or identified contaminant(s). If required, the water will be analyzed by appropriate analytical methods to determine its waste characteristics. If a water treatment system is available wastewater will be treated on-site, thus eliminating the need for disposal. A portable aeration system can also be utilized to eliminate volatile contaminants in wastewater. In any event, the ultimate disposition of water will be in accordance with all applicable regulations.
