LEGAL DESCRIPTION AND PROOF OF OWNERSHIP The Sevier County Sage Flat Solid Waste Landfill is located in Lots 3 through 6, 12, and the West ½ of the Southwest ¼ of Section 3; Lots 1 , 9, 10 and the East ½ of the Southeast ¼ of Section 4; the Northeast ¼ of the Northeast 1/4 of Section 9 and the West ½ of the Northwest ¼ of the Northwest ¼ of Section 10 of Township 23 South, Range 1 West, SLBM approximately four miles east of Sigurd Utah. The site occupies approximately 460 acres of property. In 1994, Sevier County purchased the property from the Bureau of Land Management (BLM). 1.2. WASTE TYPES CURENTLY ACCEPETED The following types of waste are currently accepted at the Sage Flat Landfill facility: • Non-hazardous solid waste that may include: o Municipal solid waste o Commercial waste o Industrial waste o Construction/demolition waste • Special waste as allowed by R315-315 of the Utah Administrative Code and authorized in Section III-I of the site’s permit. o Special wastes currently accepted include ash, animal carcasses, and asbestos waste Jones & DeMille Engineering Sevier County Sage Flat Landfill Page 2 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION • Conditionally exempt small quantity generator hazardous waste as defined in R315-303- 4(7)(a)(i)(B) 1.3. COMPOST SITE WASTE ACCEPTANCE The proposed compost site for the Sage Flat Landfill will accept the following types of waste: • Yard and garden waste (already permitted and accepted) • Clean woody construction material (already permitted and accepted) • Grease trap waste • Animal mortalities • Butcher residuals Discussions with local businesses suggest roughly 3,200 tons per year of animal products will be sent to the compost site. The grease trap waste anticipated to be sent to the compost site is approximately 3,000 gallons per month from a single pumping company. 2. SITE INFORMATION 2.1. GENERAL DESCRIPTION OF EXISTING FACILITY The Sage Flat Landfill was constructed in 1994 and occupies approximately 460 acres of property. The landfill receives municipal solid waste from all areas of Sevier County. The original expected life of the landfill was 20 years with a capacity of 1,500,000 cubic yards of waste. Modifications to the landfill increased its capacity to approximately 2,825,000 cubic yards of waste. The current remaining capacity of 1,251,692 cubic yards provides an estimated remaining life of roughly 21-years. The landfill is currently permitted to accept waste until December 22, 2029 Within the site is located a Class I landfill, a Class IV landfill, several maintenance buildings, a tire and white goods (refrigerators, water heater, other appliances, etc.) collection area, a dead animal pit, and access roads. The entire site has been surveyed and marked to ensure that all facilities are within the boundaries of the property. The boundary is marked with barbed wire and chain link fences. However, there is high relief terrain on the southeast portion of the site and there is no fencing in that area. There is a paved access road from state Road 24 to the landfill entrance. The roads within the landfill site are gravel to provide access to the various disposal areas. An overview map of the landfill layout is included in Appendix A. The landfill is located at Sage Flat, a remote narrow, north-south trending valley approximately four miles east of Sigurd, Utah. Sage Flat is in a semi-arid region of Utah receiving an average annual precipitation of less than 1O-inches. The landfill is in a roughly 3,000-foot-wide valley in the Cedar Mountains. The surface topography in the area of the Class I site is relatively flat and slopes gently to the south. South of the Class I site, the valley narrows, and the surface topography slopes down about 80 feet before reaching the flat lying area of the Class IV site, where the valley widens again. The Sage Flat Jones & DeMille Engineering Sevier County Sage Flat Landfill Page 3 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION soils are derived from alluvium and alluvial fans revealing sequences of silty clays, silts, silty sands, and gravel with occasional cobbles. The upper-most aquifer that underlies the site occurs in the unconsolidated alluvium under water-table (unconfined) conditions. Depth to the groundwater under the proposed Class I and IV sites is approximately 165 and 950 feet below the ground, respectively. The land use of adjacent properties to the Sage Flat Landfill boundary are designated as grazing, recreation, and forestry (GRF-l). 2.2. AREA SURVED BY FACILITY The Sage Flat Landfill serves the residents and businesses within the boundaries of Sevier County. Sevier County has an area of 1,918 square miles. Sevier County is located in Central Utah and is mainly a rural, Agricultural County. Richfield City is the county seat and located along Interstate 70. From the 2020 census, the population of Sevier County was estimated to be 21,522. 3. PUBLIC PARTICIPATION REQUIREMENTS The property surrounding the Sage Flat Landfill is entirely owned by the US Bureau of Land Management (BLM). The contact information for the Utah State Office of the BLM is: Utah Office of the Bureau of Land Management 440 West 200 South, Suite 500 Salt Lake City, UT 84101 801-539-4001 blm_ut_so_public_room@blm.gov The BLM was notified of the application for a composting facility via letter in January of 2025 and a copy of the letter is included in Appendix B. 4. LOCATION STANDARDS FOR COMPOST FACILITIES The proposed compost facility will be located in a remote area of Sevier County. The landfill currently accepts animal mortalities for burial. The change to composting should reduce the odors generated. The site’s remote location further reduces the risk of odor complaints from neighbors. The facility sits on soils with a high clay content which reduces the risk of groundwater contamination. 4.1. SITE RUN-ON AND RUN-OFF The landfill currently has a run-on control system designed for the 25-year storm surrounding the property. This system will prevent run-on from entering the compost site. An existing landfill drainage ditch runs across the eastern and southern borders of the compost site. A second ditch will be added across the northern boundary to capture runoff in that direction. The new ditch will be sized to handle the 25-year compost site storm run-off and convey the flow to the landfills existing drainage system. Any solids or debris carried into the drainage system will be captured in existing detention basins and Jones & DeMille Engineering Sevier County Sage Flat Landfill Page 4 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION removed for proper disposal. The new compost site run-off ditch will be constructed following details found in the landfills Operating Permit and shown in Error! Reference source not found.. 4.2. WETLANDS AND WATERCOURSES According to the National Wetlands Inventory (NWI) there are 2 ephemeral streams that cross the landfill. When the landfill was built the northern watercourse was conveyed through the site. The southern watercourse currently drains naturally into a small detention pond on the landfill property. A drainage ditch sized for the 25-year 24-hour storm event will be constructed to better direct this watercourse into the pond. The ditch will be constructed according to details found in the landfills current operating permit and shown in Appendix C. An NWI map of the landfill site is included in Error! R eference source not found.. 4.3. SURROUNDING STRUCTURES The Sevier County Sage Flat Landfill is located in a remote valley with no surrounding structures of any kind. The maps found in 0 show that there are no permanent residences, schools, hospitals, institutions, office buildings, restaurants, churches, or structures of any kind within 500 feet of the landfill. In addition, the compost site is roughly 2,500 feet from the nearest landfill structure. 4.4. HISTORIC PRESERVATION The proposed compost site is above closed and covered waste trenches. Historical and archeological identification efforts for the proposed site would have been conducted when permitting the closed waste site. Because the site has already been used for waste disposal and is heavily disturbed no historical or archeological identification was performed. A notice of concurrence from the state historic preservation officer showing no historic properties will be affected by the compost site is included in Error! Reference source not found.. 5. CONSTRUCTION SCHEDULE The proposed site is accessed by existing facility roads and will only need minor site grading, drainage construction, and compaction. The landfill and county employees will conduct all construction activities. Construction will begin as soon as possible. The project could start as soon as April if an operating permit is approved and the ground dries sufficiently for construction. From start to finish the project is estimated to take approximately 2 months. Jones & DeMille Engineering Sevier County Sage Flat Landfill Page 5 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION 6. FINANCIAL 6.1. STARTUP COSTS The landfill has the necessary equipment and knowledge to construct the compost site in-house. Soil in the landfill and surrounding areas is high in clay and will be used for the composting floor. The clay soil will be graded and compacted to provide a smooth low permeability liner. A drainage berm and ditch will be created to direct compost site run-off to an existing detention basin. The estimated costs for the compost site can be found in Table 6-1. Table 6-1 Estimated Compost Site Startup Costs Task Quantity Units Unit Cost Total Cost Site Grading C.Y. 2,750 $3.00 $8,250 Soil Compaction S.Y. 14,000 $1.00 $14,000 Drainage System Excavation L.F. 1,500 $1.00 $1,500 Long Stem Thermometer 4 Each $2,000 $8,000 Total $31,750 6.2. OPERATIONAL COSTS The landfill plans to hire a contractor to operate the compost facility for the initial years of operation. Hiring a contractor will provide lower startup costs for the landfill, reduce the needed employees, and allow the landfill to learn from the contractor. The yearly cost for a contractor to run the facility is expected to be covered by the sale of compost. In the future the landfill may operate the compost site in-house. If the landfill takes over the operation, they may purchase a compost windrow turner and hire a new employee. The Turner is expected to cost $90,000 and the employee pay will be covered by compost sales and tipping fees. The turner will reduce the time required by the compost operator but is not needed as the piles can be turned with a loader. 7. PLAN OF OPERATION 7.1. WASTE HANDLING PROCEDURES A member of the County Commission will always be designated as the Director of Solid Waste Services and have supervisory responsibility over the landfill. Daily operation of the landfill is under the direction of the Landfill Manager. When the Landfill Manager is absent, a senior operator will be designated to be in charge of the landfill. At the beginning of each working day, the Landfill Manager is responsible for informing his operators where to direct the various types of waste for disposal. The operator will direct each customer to the proper location for disposal of the waste. The landfill will be always attended by an operator or the Landfill Manager during landfill operating hours. Jones & DeMille Engineering Sevier County Sage Flat Landfill Page 6 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION The landfill has a scale for weighing waste loads that are brought to the landfill. The scale is located at the main entrance to the landfill, next to the maintenance building. Each waste load is weighed prior to disposal. The landfill has the following equipment available for use on the compost site: o John Deere 624k Loader o Caterpillar 938M Loader o Caterpillar 973 Track Loader o Caterpillar 826K Compactor o Caterpillar D8T Dozer o 2 Peterbilt Dump Trucks o GMC Service Truck o Ford F-250 Pickup o Kenworth T-300 Water Truck o Sheepsfoot Compactor 7.1.1. PROCEDURES FOR EXCLUDING THE RECEIPT OF HAZARDOUS WASTE The following types of waste will be accepted for use by the compost facility: • Yard wastes • Food wastes • Clean paper waste • Animal mortalities • Butcher remnants • Clean biodegradable construction material • Sawdust • Animal manures • Pre-solidified blood passing the paint filter test described in EPA Method 9095B The following types of waste will not be accepted at any time for composting: o Hazardous wastes as defined in R315-261-3 o PCB’s as defined in R315-301-2(53) o Toxic waste o Chemical wastes o Treated woods Signage specifying the acceptable and unacceptable waste types will be posted at the landfill gate. The operator at the gate and the operator at the compost site are each responsible for identification and prohibition of excluded wastes. All employees will be trained in methods and techniques for spotting prohibited liquid waste, drums, waste in sealed containers, red-bag waste, and waste which exhibits unusual odors or markings. These methods and techniques will be used for thorough inspections at the gate. All such waste will be refused access to the landfill; if such waste is discovered at the compost site it will be segregated from the other waste pending alternative disposal. When possible, information on Jones & DeMille Engineering Sevier County Sage Flat Landfill Page 7 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION violators of the hazardous waste policies will be recorded including date, name of hauler, and license plate number. The generators of any animal products will be required to certify that the waste does not contain hazardous materials. Large generators will also be required to have animal products tested on a quarterly basis to verify no hazardous waste is present. Records of this testing will be maintained in the main landfill building. At least one percent of incoming compostable loads will be inspected. Loads will be selected at random by the operator at the gate. The vehicle will be stopped, and the operator will conduct a trained inspection, looking specifically for prohibited waste materials. A “Waste Inspection Report” form (see Error! Reference source not found.) will be completed and filed on every inspection conducted. The d aily operating log also notes waste inspection conducted (see Error! Reference source not found.). The Landfill Manager will have the ultimate authority and responsibility to decide whether to accept or reject waste material. 7.1.2. FUGITIVE DUST AND LITTER CONTROL The landfills water truck will be used to wet down traveled areas, areas of heavy excavation activity, and the compost windrows to reduce fugitive dust generation. The compost site will consist of two separate areas namely a green waste area and the composting area itself. The green waste site is already used and is surrounded by a large dirt berm that limits wind and prevents litter from leaving. If any litter is blown from the site, it will be collected by the perimeter fence. The composting area should have minimal litter present as the majority will be removed in the green waste area. Any litter in the compost windrows will be controlled with the addition of water and windrow mixing. Roughly every two weeks an inmate work crew from the Sevier County Jail will gather all visible litter from the perimeter fence, the green waste berms, and the compost windrows. 7.1.3. PROCEDURES FOR CONTROLLING DISEASE VECTORS Disease vectors in the compost will be controlled through temperature and the green waste cover of the animal products. No animal products will be left uncovered beyond the day they are accepted. The windrows will be left unturned for up to 6 months after initial cover to allow full decomposition of animal products in a protected environment. Surface water controls will be used to reduce ponding issues and further reduce disease vectors. 7.2. RECORD KEEPING AND REPORTING The landfill manager maintains the following operating records for the compost site: • Record of waste accepted (Animal product acceptance form found in Appendix F) • Record of windrow monitoring (Record form found in Appendix F) • Records of operator training Jones & DeMille Engineering Sevier County Sage Flat Landfill Page 8 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION • Generator certifications of non-hazardous wastes Any waste type that can be sent to the Class I or IV sites will be recorded on the landfill’s existing recording forms. 7.3. MAINTENANCE AND INSPECTION SCHEDULE AND LOG A schedule is provided in Table 7-1 to ensure proper operation and monitoring. Table 7-1. Inspection and Monitoring Schedule Inspection/Monitoring Activity Frequency Windrow temperature Daily Access road conditions and maintenance As needed during operation Fence inspection and maintenance Monthly Run-on containment systems Monthly or following significant storm events Composting area Monthly and after clearing a compost windrow Run-off containment system Monthly or following significant storm events Landfill equipment maintenance Per manufacturer recommendation or as needed Gas monitoring Quarterly The following monitoring equipment and documentation will be housed in the landfill’s main office: long stem thermometers, waste acceptance records, maintenance equipment, compost monitoring forms, site schematics, and equipment maintenance records. 7.4. COMPOSTING Composting is a biological process where organic products are broken down into a soil-like substance by invertebrates and microorganisms. Waste types already accepted by the landfill such as yard waste, paper waste, food waste, animal products, and certain construction waste are used for the composting process; thereby reducing the amount of waste requiring traditional disposal. The product, compost, is then used to improve soil in the surrounding communities. Compost operations therefore benefit both the landfill and the surrounding population. To achieve the fastest and most efficient composting requires controlling four main factors: carbon, nitrogen, oxygen, and temperature. The compost site will use grass, wood chips, garden wastes, clean biodegradable construction material, sawdust, and paper wastes as the carbon source. The addition of wood chips or other bulky pieces is critical to the compost process as they create airways and allow oxygen to enter the compost. The facilities nitrogen source will consist of animal mortalities, butcher residuals, pre-solidified blood, grease trap waste, and food waste. The time required for complete composting will depend on the carbon to nitrogen ratio, surface area, moisture content, temperature, and the size of the nitrogen source type. The temperature will be the main source of control during the process and is adjusted by altering the surface area, water content, Jones & DeMille Engineering Sevier County Sage Flat Landfill Page 9 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION and frequency of turning. The estimated duration of composting will be 2-12 months depending on the materials used as a nitrogen source. Full animal mortalities will require the longest time frame due to the large size of the material. The smaller compostable materials, such as food waste, will produce a ready compost in the shortest time. 7.4.1. COMPOSTING PROCESS Aerated windrows will be utilized as the composting method. Because the composting process can vary depending on site conditions and input materials the exact process will vary from windrow to windrow. A composting contractor will initially be used to work the site and to improve their composting process when possible. The general process will consist of the following steps. 1. Before the composting process can begin, sufficient green waste material will be produced on site or purchased. Large woody materials such as tree trimmings or clean biodegradable construction wastes will be chipped to pieces with an average size of 1-2 inches. The chipped material will then be mixed with other garden waste products in a roughly 1:1 ratio. The mixture of mulch and garden waste is needed to provide a cover material that both allows airflow and provides small material that is easily broken down by the composting process. 2. Because the site is over a closed waste trench, care will need to be taken to avoid surface damage. Before any new compost windrows are created the site will be inspected and re- graded/compacted as necessary. 3. A bedding of the green waste mixture will be laid out 10-12 feet wide and 2 feet deep. This bed will act as both a carbon source for composting and a sponge to prevent liquid runoff. 4. The windrows will be assigned a number and temperature monitoring sheet. 5. Separate windrows will be created for large animal carcasses, butcher residuals, and small compostable materials. The nitrogen sources will be placed 1-2 feet deep on the green waste bed. A cover layer of green waste mixture 2 feet deep will be placed on the tops and sides. A second layer of nitrogen source will be added followed by a final cover of green waste mixture. The nitrogen sources will be covered at the end of each business day to reduce odors, disease vectors, and animal activity. 6. The finished windrows will be roughly 10-12 feet wide, 8-10 feet tall, and 400-500 feet long. 7. After a windrow is finished it will be left unturned to allow for decomposition. The length the row will be allowed to sit will vary based on the nitrogen source. Full animal carcasses will be left for up to 6 months, butcher residuals up to 2 months, and the other small compostables up to a week. 8. Moisture content will be kept between 40-60 percent and will be monitored using the “squeeze test”. Raising the moisture will be done with the sites water truck. If the water content is too high the row will be turned or have dry green waste added. 9. Internal windrow temperature will be checked and recorded 3 times per day using a long stem thermometer. Due to the length of the windrows, temperature will be monitored at both ends and near the middle. When not in use the thermometers will be stored in the main building at Jones & DeMille Engineering Sevier County Sage Flat Landfill Page 10 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION the landfills gate. Temperature monitoring will not begin until after the initial resting period ends. 10. After sitting for the required decomposition time, the piles will be turned with a loader or specialized compost turner. This will improve aeration and ensure complete composting of the windrow. The turning frequency will vary depending on the nitrogen source and internal windrow temperature. Rows will be turned when temperatures exceed 140°F or drop below 90°F. If composting is proceeding in a way temperatures do not leave this range, then full animal carcass windrows will be turned monthly while butcher residuals and small compostable windrows will be turned weekly. 11. A compost windrow will be considered complete when the temperatures begin to drop, even with turning. A prolonged temperature drop, even after turning, suggests diminished microbial activity and completion of the composting process. Completed compost material will be screened to remove any metals or large materials. The screened compost will be stockpiled for public sale. Any materials removed by the screen will be disposed of in the proper manner or re- composted. The green waste used for bedding and cover will mainly come from green waste sites around Sevier County. Initially the woody material will be chipped by a contractor and stockpiled for later use. In the future the landfill may purchase and operate their own chipper. The mixing of green waste and creation of windrows will be accomplished with the facilities existing loaders. The thickness of green waste and nitrogen source layers will be adjusted based on the composting process. If the temperature of the windrows is low, indicating slow composting, the green waste layer will be increased or the nitrogen will be decreased in future rows. If an ammonia odor is generated by a windrow, then more green waste will be added to the row and future row layering will be altered. 7.4.2. COMPOST USE AND STORAGE The final compost product is meant to be sold the public. This will require effective monitoring of temperature during the process to ensure the product can be considered compost. Before being classified as compost the temperature must reach between 104 and 149°F for at least 5 days. The compost must also reach at least 131°F for a consecutive 4 hours in that five-day period. If a windrow does not reach the proper temperatures, it cannot be classified as compost and the material will be re- composted or sent to the Class I landfill for disposal. Compost sold will be weighed and fees collected at the existing facility scale house. At least 50% of a completed compost row will be removed within two years, as outlined by the site’s permit. 7.4.3. SITE CONSIDERATIONS Several site considerations will improve the efficiency of the composting process. The windrows will be created in a north to south orientation. This is needed during winter months to allow both sides of the windrow to be hit with sunlight. If the windrows run from east to west then the north facing side can freeze in winter months, delaying the compost process. Jones & DeMille Engineering Sevier County Sage Flat Landfill Page 11 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION The site will also be graded so that seepage from windrows will run to the neighboring pile. The downhill ends of compost windrows will have small berms protruding to catch any runoff that escapes a windrow. This will help reduce odors and disease vectors caused by uncontained seepages. Maps of the compost site are included in Appendix A and construction drawings with details are included in Appendix C. 7.4.4. ADVERSE OPERATING CONDITIONS The following adverse operating conditions will be handled with the procedures listed below: Wind: Additional water will be added to the windrows as necessary to increase moisture content and reduce fugitive dust. Heavy Rain: Drainage systems will be monitored and maintained as necessary during heavy rains. Drainage between windrows will also be monitored and maintained, as necessary. Snow and Freezing Temperatures: During winter months the windrows will be built with extra cover to provide insulation. Melting snow will provide water content and increase moisture thereby reducing watering requirements. During winter months the composting process will likely be slowed and increased time will be added to ensure complete composting. 7.5. CONTINGENCY PLANS Contingency plans are designed to minimize hazards to human health and the environment. These plans are created to handle any unplanned discharge to air, soil, or off-site water bodies. The provisions of this plan shall be carried out immediately when there is an emergency situation or release which could threaten human health or the environment. Emergency evacuation of the site will not be necessary given the nature of the waste materials stored and processed at the site. The nature of the materials used for composting creates a low probability of fire, explosion, or toxic vapor generation. Contingency plans are as follows: 7.5.1. FIRE OR EXPLOSION The primary means of fire control will be the exclusion and or isolation of hot or burning loads. In the event that fires do erupt during operating hours, the burning material will be separated from other material and covered with soil, using onsite earthmoving equipment. This action will be supported, when necessary, by the availability of additional equipment owned and operated by the County Road Department. Small fires may be extinguished with the fire extinguishers provided in site vehicles or by using the site water truck. Upon notification of an onsite fire or explosion which is not controllable with onsite fire protection equipment, a long blast on a vehicle horn will be sounded, nonessential equipment will be shut down, and all site personnel will assemble outside the landfill entrance. The Sigurd Fire Department will be alerted, and all personnel will move to a safe distance from the involved area until the fire is extinguished. Secondary fire control will be supported by the Richfield City Fire Department and other Jones & DeMille Engineering Sevier County Sage Flat Landfill Page 12 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION fire departments in Sevier County as needed. The telephone number and location of the nearest fire station will be displayed in a conspicuous place in the site office. The landfill employees will participate in a fire drill conducted semi-annually. Fires which occur during times that the landfill is closed are more difficult to control due to the time available for the fire to spread. If a fire is reported after hours, the Landfill Manager may utilize site equipment to segregate the burning portion and bury the fire with soil. Otherwise, the local fire department will be summoned to fight the fire. 7.5.2. EXPLOSIVE GAS RELEASE Under proper operating conditions a compost pile will not generate any significant amount of explosive gas. However, the landfill Manager is responsible for quarterly monitoring of landfill gas using a methane detection meter capable of measuring methane at levels below the Lower Explosive Limit (LEL). Gas monitoring will be conducted to test for methane at the LEL at the facility boundary and at twenty five percent of the LEL in the facility structures. In the event that explosive gases are detected above the LEL during monitoring, or at any other time, the emergency audible alarm and evacuation procedures will be implemented. 7.5.3. FAILURE OF A CONTAINMENT SYSTEM No containment system is being proposed for the site because the composting operation will not be accepting domestic sewage sludge, septage, or municipal solid waste. 7.5.4. GROUNDWATER Because the composting operation will not be accepting hazardous wastes there is little risk to groundwater. The aquifer below the site is also roughly 950 feet below the surface, allowing adequate time for natural treatment of water. No additional groundwater monitoring is being proposed at the site. The groundwater plans described in the landfills current permit will be used at the composting site. 7.5.5. EQUIPMENT FAILURE The existing landfill facility has a several loaders available. In the event the primary composting equipment is unusable for any reason, the facilities other equipment will be used for temporary compost work. Composting contractors may also be hired temporarily to handle compost operations until the landfill equipment is returned to usable condition. 7.6. TRAINING & SAFETY PLAN FOR SITE OPERATION Each employee who works with solid waste at the Sevier County Landfill facility will be trained and have a working knowledge of basic maintenance and operational techniques necessary to operate and maintain the landfill facility in a manner which does not endanger human health and safety or Jones & DeMille Engineering Sevier County Sage Flat Landfill Page 13 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION environmental quality. Training will be accomplished through on-the-job training (OJT) and classroom training sessions. Training sessions will be those sponsored by the Solid Waste Association of North America (SWANA). All operators and managers will complete at a minimum the following courses of instruction: “Landfill Operator Training,” and “Waste Screening at Municipal Solid Waste Landfills.” The training program will be directed by the facility manager, or a designated professional trainer. Initial OJT will be completed within three months of employment followed by completion of SWANA courses within one year. TRAINING SCHEDULE A. Introductory Training (half hour minimum): Synopsis of solid waste regulations, record keeping and transporter requirements. Requirement: All Personnel Method: OJT Review: Annual B. Policies and Procedures (half hour minimum): Security, inspections, and emergency response. Requirement: All Personnel Method: OJT, lecture/video course Review: Annual C. Safety (one hour minimum): Personal protection, hazardous waste recognition, hazardous material handling, emergency response and first aid. Requirement: All Personnel Method: Lecture/video course Review: Annual If the landfill decides to begin operating the composting site in-house, compost training will be added to the training schedule. The “Managing Composting Program” offered by SWANA will be a required training for the landfill manager and selected operators. The course is available online and will be reviewed every 5 years. All employees operating the compost site will meet monthly to discuss any issues and determine corrective actions. Training records will be kept in the main landfill building for at least five years. Jones & DeMille Engineering Sevier County Sage Flat Landfill Page 14 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION 7.7. CLOSURE AND POST-CLOSURE 7.7.1. CLOSURE AND POST CLOSURE CARE If possible, final closure of the composting site will be up to 12 months after the final waste load is accepted. This will allow all materials at the site to be composted. Within 30 days of closure, all compost, mulch, and material will be removed from the composting site. Any remaining material that has not been fully composted will be disposed of in the Class IV landfill site or transported to an appropriate disposal location. Any remaining finished compost will be given to the public or stockpiled for use as an alternative cover. Any standing water on the composting site will be evaporated or disposed of properly. Native soils will then be graded over the compost site to ensure no standing water in the future. Post closure monitoring and activities will follow the requirements in R315-302-3. Because the compost site is located on the cover of a previously closed waste trench, monitoring is already described in the facilities plan of operation. After successfully closing the compost area, the site will be recorded as having been a composting facility with the county recorder. 7.7.2. CLOSURE AND POST CLOSURE COSTS The estimated closure costs are shown in Table 7-2. For the closure cost estimates it was assumed that 1,000 cubic yards of compost will require hauling to the landfills Class IV site and 2-inches of native cover is graded over the site. Table 7-2. Estimated Closure Costs Task Quantity Units Unit Cost Total Cost Remaining Compost Removal 1,000 C.Y. $5.00 $5,000 Site Grading/Topsoil Cover 3,900 C.Y. $3.00 $11,700 Reseeding Compost Site 1 L.S. $2,500 $2,500 Total $19,200 Jones & DeMille Engineering Sevier County Sage Flat Landfill Page A-1 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION APPENDIX A.

Jones & DeMille Engineering Sevier County Sage Flat Landfill Page E-1 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION APPENDIX E. HISTORIC PRESERVATION SURVEY December 20, 2024 RE: Sevier County Landfill Permitting; Case No. 24-3141 Sevier County is applying to include a composting facility at their existing landfill that will require a new permit with the Utah Department of Environmental Quality. The current permit will also be modified to authorize a high-liquid waste facility (e.g., grease trap waste) and construction of the animal pits. The proposed composting facility and high-liquid waste are within previously disturbed areas of the landfill. The area for the animal pits has not been obviously disturbed, but we believe the area would have been culturally surveyed and cleared recently for BLM’s authorization of the landfill expansion. Due to the project activities occurring wholly within the authorized landfill, I recommend a finding of No Historic Properties Affected. Please contact me with any questions about this request; (435) 893-5203 or jenna.j@jonesanddemille.com.
