Hansen, Director Division of Waste Management and Radiation Control PO Box 144880 Salt Lake City, Utah 84114-4880 cc: Wade Hess wadehess@utah.gov Sent via Certified Mail and E-Mail Re: Utah Department of Waste Management and Radiation Control Issuance of Temporary Waste Storage Permit to Environmental Energy Innovations, LLC Mr. Hansen, I represent Integrated Water Management, LLC (“IWM”). It has come to IWM’s attention that on August 8, 2023, DWMRC issued an approval letter for a temporary storage permit for Environmental Energy Innovations, LLC (“EEI”). [Attached hereto as Exh. “A”.] Unfortunately, the temporary storage permit application presented by EEI suffers from a number of fatal deficiencies, and should never have been approved. IWM calls each of these deficiencies into question, as detailed below, and hereby requests immediate revocation by DWMRC of the non-conforming permit. In addition to the below, IWM has contracted with Wasatch Environmental to audit the EEI temporary permit application for additional non-compliance with state, local and federal rules and regulations, which will be forthcoming. 1. EEI’s permit application does not indicate the site has a Standard Design liner, nor has the Director given approval for an Equivalent or Alternative liner. The approval letter is contingent upon EEI’s compliance with, among other regulations, R315-314-(2)(2)(a-c), requiring that the waste pile have a conforming liner in place. It is clear from the permit application that EEI does not have a “Standard Design” liner. It is also clear, there has been no separate approval by the Director for an “Equivalent” or “Alternative” Design pursuant to R315-303-3(b) or (c). Additionally, if EEI is relying on either an Equivalent or Alternative Designs, it must demonstrate comprehensive soil testing to indicate whether the site is suitable for either, which, again, is absent on the face of the application. Thus, EEI’s waste pile 2 has no conforming liner, nor approved Equivalent or Alternative design, and its temporary permit approval must be revoked. 2. EEI’s permit application fails to affirm the contents of the waste pile and whether the waste pile located at the site is greater than 10,000 cubic yards. As DWMRC knows, R315-314-2(2)(c) requires that any waste pile greater than 10,000 cubic yard shall have either a ground water monitoring system that complies with R315-308, or, a leachate detection, collection and treatment system. Here, the application, and issued permit, fail to address definitively whether or not EEI’s waste pile is larger or smaller than the 10,000 cubic yard threshold, which should have mandated denial in the first place, and requires revocation of the permit. In fact, the application also has failed to characterize the waste in the pile—DWMRC has no information whatsoever about whether any of the material presently stored at the site is or is not exempt. As a result, without further testing, the application should have been denied on its face. 3. EEI’s permit application has failed to adequately characterize the groundwater at the site. R315-302-1(e) prohibits any new waste storage facility from being located over an aquifer, or IB-classed groundwater. EEI’s application does include a groundwater analysis, however, the samples are limited only to fifty feet. The analysis fails to affirm that the site is not located at an aquifer, and given that there is no complying liner, the groundwater studies must be performed to at least 100 feet to rule out the possibility of contaminating any aquifer. In many cases, DOGM, DWMRC’s predecessor, required applicants to have testing boreholes down to 200 feet to rule out the possibility of aquifer and groundwater contamination. Given that such studies and affirmations are missing from the application, those deficiencies alone should have mandated denial. Given that, IWM requests revocation of the permit on this basis alone. 4. Conclusion In summation, this temporary permit should never have been issued based on the application presented. Its numerous deficiencies more than mandate immediate revocation of the permit. IWM hereby formally requests such immediate revocation, which, if not done by DWMRC by Friday, November 3, 2023, IWM will have no choice but to seek administrative review and other legal recourse.

The property is fenced, bermed, and divided into 12 cells, each approximately 10 acres in size. See attached facility layout drawing. The loading area includes a concrete pad and lined holding ponds that function in separating liquid from solids arriving on hydro excavators. There are 3 - 400 bbl insulated hot water tanks for dust control and the occasional cleaning of equipment and concrete surfaces, see attached solid separator drawing for details. There is a small office trailer. Small tools are stored in a con-ex located on site. Equipment used on the site includes Front End Loaders (2), Dump Trucks (2), Backhoe (1), Farm Tractor (1), and miscellaneous discs, rippers, tillers. Surface Water The Bridgeland Quadrangle map shows an intermittent stream located approximately 950 feet southwest and 528 feet northwest of the project. These stream beds consist of desert shrub vegetation. There is an irrigation canal 4,488 feet northwest of the project. The streams and canal are at a lower elevation than the project. See attached water and contour map. Storm Water Annual precipitation for the project area is below 10 inches per year. See attached precipitation map. 1.0 OPERATIONS PLAN 1.1 SCHEDULE OF CONSTRUCTION The 140 =/- acre property has been operated as a bio-remediation land farm since 2011. The proposed facility is sectioned into 12 10 acre =/- cells plus a 10 acre area for operations, parking, office, and water tank battery. A 2-to-8-foot berm will surround each cell with slopes no steeper than 33% to prevent storm water from entering or leaving each cell. Berms are constructed from existing site soils excavated from the property. A detail of the EEI Facility berm is attached in the solid separator drawing. Page | 2 To the south, adjacent to the facility will be a waste staging area where waste delivered to the site will be inspected and treated, if necessary, prior to disposal. Waste that requires treatment will be processed in a waste concrete holding area designed to protect ground water from possible waste contamination. Drawing details of the waste staging area are attached see the solid separator drawing. At the start of operations, EEI anticipates approximately 70 cubic yards of E & P waste will be transported to the proposed facility per day. EEI is considering using several different products and processes to stabilize the waste. Some of the products that may be used for mixing and stabilizing the waste include but are not limited to sawdust, native soils, lime, potash, or remediated soils from any of the 11 cells currently not in use receiving waste. EEI may also process the waste to remove liquids by drying the waste in the concrete storage area. Waste acceptance procedures and quality control of waste being disposed in the facility are outlined in sections 1.2.1 and 1.2.2 of this report. Each of the 10-acre cells will be filled to closure capacity one cell at a time. Once the final process is defined adjustments to the design life of the facility will be made. At this point the life duration of the facility is defined assuming that half of the waste arriving at the facility will be mixed with remediated soil and the remaining waste will be processed using other equipment [mixing, drying] and then placed directly into one of the facilities cells. Waste that will be mixed with additional material will need to reach a moisture content that is workable. In order to obtain an estimate for the mixing ratio, a preliminary waste assessment was conducted using samples of anticipated types of waste and remediated soils that will be disposed of in the EEI facility under this permit application. During this assessment it was determined that the mixing of remediated soils with waste when needed will be done at a ratio of approximately 1.5:1 respectively, in order to reach a waste moisture content that will be suitable to be spread on the site. In other words, for every 1 Cu. Yd. of waste there will be approximately 0.5 Cu. Yds. of remediated soils added to reach a moisture content that is workable. Based on waste mixing assumptions described above and assuming waste will be accepted 6 days per week with a 10% growth rate over the life of the facility up to 50,000 cubic yard per year, the projected life of the facility is approximately 85 years. However, the projected life may increase or decrease based on the type of processing and/or mixing methods utilized. A copy of the spreadsheet used to calculate this estimated life is included in the closure plan. All assumptions presented in the previous paragraphs were used in the spreadsheet calculations. 1.2. DESCRIPTION OF WASTE HANDLING PROCEEDURES The following sections describe the general procedures that will be followed under this permit application for accepting, disposing, recording, and excluding waste at EEI. 1.2.1 General Procedures All waste will be hauled to EEI using commercial or independently owned trucks. All trucks will enter at the main gate and check in with the EEI facility office. Every truck load of waste will be inspected for liquids and inappropriate waste prior to disposal. Waste that appears to be stable, free of liquids, will be directed to the appropriate cell for placement. Waste that is unstable, has excessive liquid Page | 3 content, will be placed on the concrete pad for further processing. The concrete pad is designed to separate liquids from solid waste. The liquids drain off into lined holding ponds. Liquids are then collected and loaded into a vacuum truck and sprayed onto a dry cell. After the solid waste has been separated from the liquid waste and mixed with other solid materials, the solid waste will be removed from the concrete pad and then placed in the appropriate cell using heavy equipment or a conveyor system. All waste will then be placed in a uniform layer in the current working cell. 1.2.2 Waste Shipment Records The EEI facility operation manager will maintain and store waste shipment records as part of the daily record of disposal activity. Each truck load of inbound waste will have a load ticket completed by the truck driver and verified by the EEI facility operating staff. An example of the load ticket is included below. See Figure 1. Figure 1 Page | 4 1.2.3 Waste Disposal Waste deposited in one 10-acre cell will be placed in 1 ft. thick lifts and compacted to reach a firm and unyielding surface to maximize facility capacity. EEI will distribute inbound waste to the same 10-acre cell until the capacity of that cell has been reached. Closure of the cell will occur at that time and EEI will direct new waste material to one of the remaining eleven cells. 1.2.4 Plans For Excluding Waste Non-hazardous industrial waste including E&P waste and RCRA exempt waste will be accepted at the EEI facility as allowed as directed by DWMRC. To ensure that waste meets this requirement, all potential waste generators disposing of waste at EEI proposed facility must first complete a waste profile assessment to determine the acceptability of the waste according to this permit application. Representative samples of each type of waste will be provided to EEI by all generators for testing. Generators will provide a waste characterization form certifying that it meets the requirements of disposal from all sources. Generators will be required to inform EEI when composition changes and then resubmit a waste characterization form with samples. 1.3. WASTE FACILITY INSPECTION AND MONITORING EEI personnel will inspect the proposed facility to avoid operator error and discharges which may cause or lead to the release of wastes to the environment or to a threat to human health. Facility inspections will be conducted weekly. 1.3.1 Fugitive Dust Control As part of the daily operations of the proposed facility, fugitive dust will be monitored, and controls will be put in place as deemed necessary by the Operations Manager. These sources of dust will be controlled by watering and proper placement of waste in the facility. EEI staff will be trained in monitoring opacity and checking the facility for dust control issues. When opacity of the dust exceeds 20%, watering controls will be affected on the facility haul roads, waste cells, and common areas. 1.3.2 Plan For Litter Control EEI does not anticipate accepting waste materials that will cause a wind-blown litter problem. EEI will complete a daily inspection of the facility and the surrounding area to identify a potential litter problem. EEI does not anticipate waste that would be considered a disease vector. 1.3.3 Contingency Plan for Fire or Explosion In the event of a fire or explosion the EEI manager will contact local emergency authorities to initiate emergency response. A list of the local responders is provided, see Figure 2. Page | 5 1.3.4 Alternative Waste Handling Plan In the event of a facility closure due to an emergency or repairs, EEI will make arrangements to have the waste re-directed to other DWMRC landfills in Duchesne County or the Duchesne County Landfill located at 20550 W and 2000 S. 1.3.5 General Training Plan EEI currently has a training program to educate employees on handling waste and operating existing equipment at the EEI waste facility as required in R315-302-2[2].

The closure costs for the EEI facility are based on the cost of constructing the final cover. The final cover construction includes the placement and grading of the 6-inch clay cover, 6-inch topsoil layer and seeding of topsoil. The cost for the closure tasks is estimated at $275,000. Detailed financial assurance costs are presented below in table 1. This is the cost of just one cell. Closure Cost for 1 EEI Facility Cell Task Description Total Cost Details Closure Cost Letter of Notification of Closure $2,000 Letter to DWMRC and County Cover and Topsoil Material $240,000 Seeding/Mulching $8,000 Contingency $25,000 Total Cost $275,000 Table 1 Closure Costs POST CLOSURE CARE COSTS Post closure care of inactive sections of the EEI facility will consist of maintaining the integrity of the final and vegetative covers. Any areas subject to erosion will be corrected and appropriate measures will be implemented to identify and eliminate the run-on source. No active or technical devices are proposed for at the EEI facility. Best management practices will be implemented to minimize infiltration and assure the integrity of the run-on/run-off system. An evaluation of the system will be made during the quarterly inspections and corrective measures if any will be implemented. All run-on and run-off from events smaller than the 25-year storm will be controlled through drainage design. Post closure care costs are estimated by the cost of maintaining the previously described activities for a 30-year period. The estimated cost of the post closure care tasks is approximately $28,500.

Civil Engineering Consultants PO Box 1758 * 1256 W 400 S, Suite 1 Vernal, Utah 84078 Phone (435)789-5448 * Fax (435)789-4485 Email: civco@civcoengineering.com ENVIRONMENT ENERGY INNOVATIONS PLEASANT VALLEY, UTAH CLOSURE DESIGN PLAN Introduction At the end of the life of the Environmental Energy Innovations, LLC (EEI) facility it will be closed according to R315-302. The following is a brief plan for closure of the facility and each cell and is subject to amendment if conditions and circumstances justify an amendment. Closure Procedures The following procedures will be followed: 1. Notify the Executive Secretary of intent to close 60 days prior receipt of final material. 2. Commence closure procedures within 30 days of receipt of final material. Closure activities will be completed within 180 days of commencement of closure activities. 3. Within 90 days of completion of closure activities, submit a copy of the closure plan and certificate that closure has been performed per the closure plan. These must be stamped and signed by a State of Utah Licensed Professional Engineer. Closure Schedule It is anticipated that the proposed EEI facility will be closed, one 10-acre cell at a time, including the final grading of the waste material and the placement of the final cover. Sixty days prior to the expected final receipt of waste, EEI will notify the division of their intent to begin closure operations. EEI will begin the closure operations after the final receipt of waste is obtained. It is anticipated that each closure operation will take place over an anticipated duration of 90 to 120 days. During this period, the EEI facility cell will be graded, covered, and surveyed. As-built plans will be generated for reference for the final inspection by the division. Design of Final Cover for each 10 Acre Cell The final cover will consist of two soil layers. The lower layer will consist of a compacted clay soil liner which will be overlain by an upper layer of soil that will be seeded with native grasses. The construction of the lower layer portion of the final cover will be an Alternative Design that will achieve equivalent requirements as the Standard Design as prescribed in R315-303-3(4)(c)(i). The upper layer will follow the Standard Design requirements as explained in R315-303- 3(4)(a)(ii). Cover soils will be constructed from existing site soils. All testing and calculations are based on samples of the native soils at the site. In the alternative final cover design the waste will be covered with a minimum of six inches of clay that Page | 2 will have a permeability of at most 1 x 10 -6 cm/sec. The Utah regulation R315-303- 3(4)(c)(i) requires that the alternative final cover of a soil liner must achieve an equivalent reduction in infiltration as achieved by the standard design. Standard design calls for at least 18 inches of compacted soil, or equivalent, with a permeability of 1 x 10 -5 cm/sec or less, or equivalent. The proposed soils used for the final cover are far less permeable than this requirement. The proposed lower layer will use 6 inches of clay soils that have a permeability of no greater than 1 x 10 -7 cm/s In addition, R315-303-3(4)(a)(ii) also requires that a second layer of soil is to be used for reducing erosion consisting of at least 6 inches of soil capable of sustaining vegetative growth placed over the compacted soil cover and seeded with grass, other shallow rooted vegetation, or other native vegetation. In our proposed design follows the standard design requirements in that the compacted clay liner soils will be covered with a second soil layer that will be a minimum of six inches of soil as prescribed in R315-303-3(4)(a)(ii). This soil layer will be capable of sustaining vegetative growth and will be seeded with native shallow root vegetation or native vegetation to minimize erosion of the final cover. These soils may be tested for organic content, permeability and cohesion prior to use as final cover soil. The final cover for each cell will be graded to no steeper than a 3:1 slope around the outer perimeter of the EEI facility cell. The top elevation of each EEI facility cell will be rectangular and will have a slope of no less than 2%. To control the run-off of storm water and minimize erosion of the final cover material, it is intended that the final cover soils be seeded with native grasses and use other erosion controls as needed. The final cover may be reseeded as needed during the post closure phase of the EEI facility. The final cover plan of each cell is attached. Capacity of EEI Facility Based on the assumption of half the waste being mixed with additional material, the estimated capacity of the (1) EEI facility cell up to the final cover is approximately 343,000 cubic yards of waste plus mixing material. This calculation also accounts for an estimated dry density of 135 lb./cu-ft for the mixing material. In total, the EEI facility will store approximately 4,117,000 cubic yards of waste plus mixing material after all 12 cells are built. An additional 2,058,500 cubic yards of waste can be accommodated by filling in between the completed cells and building upward after the first 12 cells are filled in. A table with the projected life at 10 percent growth rate, capped at 50,000 cubic yards of waste plus mixing material per year, for the EEI facility is provided in Table 1 below. The growth rate is defined as the number of trucks delivered to the site on an average daily basis. With an increase in the growth rate, the life of the EEI facility will be reduced. It will take eight years for the first cell to be completed, and then seven years for each cell thereafter to be completed. This process will take 85 years to fill in 12 cells. The EEI facility can have its life expectancy extended 50 years by filling in between these completed cells with waste after the initial 12 are built, as well as building additional cells on top.

EEI will notify the division of the anticipated date of completion and plan for scheduling the inspection. POST CLOSURE CARE Immediately after the completion of construction for the final cover of a EEI facility cell, the post closure care plan will be implemented. As required in R315-302-3(5) the post closure care activities will take place for 30 years or as long as the Director determines is necessary for the facility or unit to become stabilized and to protect human health and the environment. A licensed engineer with the state of Utah will direct the post-closure care of the facility and will provide EEI with recommendations to properly maintain the EEI facility and prevent any release of harmful substances. The engineer will also provide the division with documentation if he determines that the site is safe to reduce or discontinue site monitoring prior to the end of the 30-year period. During the post closure period the following activities will take place: Site Monitoring: EEI personnel will be on site weekly to monitor activities at the proposed EEI facility and restrict access to the facility. Access to the proposed EEI facility will be restricted with fencing and locked gates at the roadway entrance. Signs will be posted advising of the potential dangers associated with the EEI facility. Only authorized personnel of EEI will have access to the site. On a quarterly basis the EEI facility cover will be inspected to check for rutting and depressions that could result in rapid erosion. If rutting or depressions in the cover are identified, they will be repaired by grading and seeding the surface. Slopes of the final cover will also be inspected and maintained. EEI Page | 4 will ensure that a 2% slope will be maintained on the top of the cover and a 3:1 slope will be maintained around the perimeter of the EEI facility. Run-off water from the final cover will be directed into the existing drainages to the north and west of the EEI facility. EEI will on a Quarterly basis inspect the run-off collection system and ensure that they are properly diverting water into the existing storm water drainages. Repairs will be made as needed. Surface and Ground Water Monitoring: No samples of surface waters will be collected because there are no observed streams, springs, or other surface waters at the site of the proposed EEI facility. Ground water will not be sampled as the test holes taken did not encounter groundwater. Record of Title, Land Use, Zoning The Duchesne County Recorder will be notified during the closure period of the completion of the disposal site. The county recorder will be provided with documentation and plats of the location of the disposal site. Notification of the closure, and location of the EEI facility will also be sent to the county recorder and zoning changes will be made if necessary. Documentation of the history of the EEI facility permanently appended to the title of record and land use restrictions will be put in place.
