1.1. LEGAL DESCRIPTION AND PROOF OF OWNERSHIP
The 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 landfill:
• 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 waste 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 will accept the following types of waste:
• Grease trap waste
• Animal mortalities
• Butcher residuals (including blood)
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. The compost facility will also take green waste
and clean biodegradable construction materials from the landfill for use in composting. The green waste
and construction materials will be stockpiled by the landfill in the existing green waste area show in
Appendix A.
2. SITE INFORMATION
2.1. GENERAL DESCRIPTION OF EXISTING FACILITY
The 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 was 20 years
with a capacity of 1,500,000 cubic yards of waste. Modifications 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
Jones & DeMille Engineering
Sevier County Sage Flat Landfill Page 3 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION
feet before reaching the flat lying area of the Class IV site, where the valley widens again. The Sage Flat
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 compost facility will serve 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 site 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
[e-mail]

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 addition of composting will reduce the amount of animal
products that are buried and should reduce the odors generated. The site’s remote location further
reduces the risk of odor complaints from neighbors. The compost facility sits on soil with high clay
content which reduces the risk of groundwater contamination.
4.1. SITE RUN-ON AND RUN-OFF
The site 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
Jones & DeMille Engineering
Sevier County Sage Flat Landfill Page 4 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION
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 removed for
proper disposal. The new compost site run-off ditch will be constructed following details found in
Appendix A.
4.2. WETLANDS AND WATERCOURSES
According to the National Wetlands Inventory (NWI) there is an ephemeral streams that crosses the
landfill near the compost site. The watercourse currently drains naturally into a small detention pond
west of the compost site. 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 Appendix A. An NWI map of the compost site is included in Appendix C.
4.3. SURROUNDING STRUCTURES
The compost facility is located in a remote valley with no surrounding structures of any kind. The maps
found in Appendix A show that there are no permanent residences, schools, hospitals, institutions, office
buildings, restaurants, churches, or structures of any kind within 500 feet of the compost site. 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 a closed and covered landfill animal product cell. 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 Appendix D.
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.

6. FINANCIAL
6.1. STARTUP COSTS
The landfill has the necessary equipment and knowledge to construct the compost site in-house. Soil in
the compost facility area 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. Road base will be added to create
safe travel corridors between compost windrows during wet weather. The landfill has a gravel pit that
can provide all the necessary road base. 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 Unit Quantity 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 Each 4 $2,000 $8,000
Road Base C.Y. 2,000 $5.00 $10,000
Total $41,750
The compost site will require a compost turner, a tractor, and a woodchipper. Preliminary costs for the
equipment needed are shown in Table 6-2.
Table 6-2. Equipment Costs for Compost Facility
Equipment Cost
Tractor $200,000
Compost Turner $200,000
Woodchipper $100,000
Total $500,000
The remaining startup for the compost site will require no land acquisition, ancillary structures, roads
other than between windrows, or transfer stations. All other operations contiguous to operating the
compost site are already in place for the landfill operations and extra costs in this area for the compost
site are not expected.
6.2. OPERATIONAL COSTS
The compost facility plans to hire a contractor to operate for the initial years. Hiring a contractor will
provide lower startup costs, reduce the employees needed, and allow landfill staff to learn from the
contractor. The landfill will lease the compost site to a contractor which is expected to generate $2,000-
5,000 dollars per month in revenue. No other costs are assumed for the landfill if the compost site is
operated by a contractor.
Jones & DeMille Engineering
Sevier County Sage Flat Landfill Page 6 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION
In the future the landfill may operate the compost site in-house. To operate in house the compost site
will require an employee for all hours of operation, or roughly 50 hours per week. Estimated yearly costs
for an employee and equipment are shown in Table 6-3.
Table 6-3. Estimated Weekly Compost Site Operational Costs
Cost Unit Quantity Unit Cost Total Cost
Employee Hour 2,500 $35.00 $87,500
Equipment Fuel Hour 624 $55.00 $34,320
Equipment Maintenance L.S. 1 $1,500 $1,500
Yearly Total Cost $123,320
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 compost facility. Daily operation of the facility 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 compost facility.
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 compost site will be always attended by an operator or
the Compost manager during operating hours.
The landfill has a scale for weighing waste loads that are brought to the compost site. The scale is
located at the main entrance, 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

All compostable materials will be sent to the compost area where they will immediately be dumped or
placed with a loader on a green waste bedding. The green waste bedding is used to reduce liquid
seepage from the compost facility. No waste will be stored by the compost facility, all waste will be
immediately added to a compost windrow. In the event that no green waste bedding is available,
Jones & DeMille Engineering
Sevier County Sage Flat Landfill Page 7 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION
compostable waste loads will be sent to the landfill. In the event that the compost accepts liquid blood
or grease for composting the load will be solidified with sawdust and woodchips on the landfill’s high
liquid waste mixing pad before composting.
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:
• Animal mortalities
• Butcher remnants
• Animal manures
• Blood and grease that has been pre-solidified by the generator or the compost facility
The following types of waste will be taken from the landfill for use in composting:
• Yard waste
• Food waste
• Clean paper waste
• Clean biodegradable construction waste
• Sawdust
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.
Acceptable waste types as well as compost site operational costs will also be available on the Sevier
County website. The operator at the gate and the operator at the compost site are each responsible for
identification and prohibition of excluded waste. 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 compost site; if such waste
is discovered at the compost site it will be segregated from the other waste pending alternative
disposal. When possible, information on 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.
Jones & DeMille Engineering
Sevier County Sage Flat Landfill Page 8 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION
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 will be
completed and filed on every inspection conducted. The daily operating log also notes waste inspection
conducted. The Compost 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
A 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 composting area should have minimal litter present. 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 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 compost manager maintains the following operating records for the compost site:
• Record of waste accepted (Acceptance form found in Appendix E)
• Record of windrow monitoring (Record form found in Appendix E)
• Records of operator training
• Generator certifications of non-hazardous waste
7.3. MAINTENANCE AND INSPECTION SCHEDULE AND LOG
A schedule for inspections and maintenance of landfill facilities to ensure proper operation and
monitoring is provided in Table 7-1.

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 waste, clean
biodegradable construction material, sawdust, and paper waste 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,
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 the composting process
Jones & DeMille Engineering
Sevier County Sage Flat Landfill Page 10 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION
when possible. Because the facility will be composting animal products the compost process will vary
slightly from normal composting operations. Normally the carbon and nitrogen sources are mixed during
windrow construction. Animal products and carcasses cannot be composted in this manner as exposed
animal products would generate noxious odors. Therefore, animal products and carcasses are buried in
green waste to allowed an initial decomposition before mixing with the carbon source. The general
process will consist of the following steps.
1. Before the composting process can begin, sufficient green waste material will be taken from the
landfill 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. A temperature monitoring sheet will be created with each new windrow.
5. Separate windrows will be created for large animal carcasses, butcher residuals, and small
compostable materials.
a. For animal products and carcasses: 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 top and sides. A second 1-2 foot layer of nitrogen source will be added followed by a
final 2-foot 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.
b. For small compostable materials: Nitrogen sources will be mixed in a 1:2 ratio with
carbon source and placed on the green waste bed. Measuring and mixing of the small
compostables and green waste for these rows will be completed with the loader bucket.
6. The finished windrows will be roughly 10-12 feet wide, 8-10 feet tall, and up to 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
the landfills gate. Temperature monitoring will not begin until after the initial resting period
ends.
Jones & DeMille Engineering
Sevier County Sage Flat Landfill Page 11 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION
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 come from the landfill and will be collected from green
waste sites around Sevier County. The woody material will be chipped and shredded by a contractor
until the compost facility is able to purchase a chipper. The mixing of green waste and creation of
windrows will be accomplished with the facilities existing loaders.
In order for the composting process to be successfully completed the ratio of carbon and nitrogen will
need to be carefully controlled. The ideal carbon to nitrogen ratio is between 25:1 and 40:1. The process
and windrow dimensions described above follow the guidance found in The Cornell Waste Management
Institutes Composting Animal Mortalities manual and the USDA Field Guide to On-Farm Composting.
Windrows constructed to the described depths and dimensions will fall within the necessary carbon to
nitrogen ratio without the need for further measuring or proportioning of materials. However, the
makeup of the green waste and compostable materials will vary, and a trained operator will monitor
and modify the procedures as needed. The thickness of green waste and nitrogen source layers can be
adjusted to meet the needs of the compost operation. Examples of adjustments that can be made are:
• 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 ADDITIVES
The composting process can be aided by the use of a variety of additives. The use of these additives will
be determined by the compost operator based on the compost process and the desired compost
properties. Many of the additives are to increase the composts soil amendment properties. The
additives that may be used and the reason for their use are as follows:
1. Probiotic cultures to help jump start or speed the composting process.
2. Limestone to raise pH levels and add calcium.
3. Bone meal to add calcium and phosphorus.
4. Clay soils to increase clay-humus compound formation (improves the composts’ performance as
a soil amendment in sandy soils)
5. Gypsum to improve the composts performance as a soil amendment.
6. Rock phosphate to add a slowly available phosphate source.
7. Sand or granite dust to improve soil drainage.
8. Seaweed meal to add potassium and trace minerals.
9. Rock meals or powders to supply trace minerals, reduce unpleasant odor, enhance humus
formation, and improve drainage.
7.4.3. 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 temperature, 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.
7.4.4. 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 by sunlight. If the windrows run from east to west then the north facing side can
freeze in winter months, delaying the compost process.
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 and construction
details for the compost site are included in Appendix A.
Jones & DeMille Engineering
Sevier County Sage Flat Landfill Page 13 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION
7.4.5. 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 rain.
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 area involved until the fire is
extinguished. Secondary fire control will be supported by the Richfield City Fire Department and other
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 compost facility employees will
participate in a fire drill conducted semi-annually.
Jones & DeMille Engineering
Sevier County Sage Flat Landfill Page 14 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION
Fires which occur during times that the compost site are closed are more difficult to control due to the
time available for the fire to spread. If a fire is reported after hours, the Compost 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 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 waste there is little risk to
groundwater. Furthermore, the aquifer below the site is roughly 950 feet below the surface and the soil
has relatively low hydraulic conductivity. This allows any seepage to be naturally filtered before reaching
groundwater. Because of this the landfill is currently not required to test groundwater and no additional
groundwater monitoring is being proposed for the compost site.
7.5.5. EQUIPMENT FAILURE
The existing landfill facility has 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 equipment is returned to usable condition.
7.6. TRAINING & SAFETY PLAN FOR SITE OPERATION
Each employee who works with solid waste at the compost facility will be trained and have a working
knowledge of basic maintenance and operational techniques necessary to operate and maintain the
facility in a manner which does not endanger human health and safety or environmental quality.
Training will be accomplished through on-the-job training (OJT) and classroom training sessions. Training
sessions will be 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,”
Jones & DeMille Engineering
Sevier County Sage Flat Landfill Page 15 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION
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 composting site is operated 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 compost
manager and compost 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.
7.7. CLOSURE AND POST CLOSURE
7.7.1. CLOSURE PROCEDURES
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
Jones & DeMille Engineering
Sevier County Sage Flat Landfill Page 16 Project #: 2411-046 UTAH COMPOST PERMIT APPLICATION
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 soil will then be graded over the compost site to ensure no standing water
in the future.
7.7.2. POST CLOSURE CARE
Post closure care and monitoring for the compost site will follow Utah Administrative Code R315-312-
3(5)(b) which states:
b. The post-closure care and monitoring shall be for five years and shall consist of:
i. The maintenance of any monitoring equipment and sampling and testing schedules as
required by the Director; and
ii. Inspection and maintenance of any cover material.
7.7.3. 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 and Post-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

Environmental Quality to authorize a composting facility at the Sevier County Sage Flat Landfill.
We are currently in the process of evaluating impacts associated with the addition of the
composting facility.

The composting facility will be within existing landfill boundaries and no impact will occur
outside of the authorized boundaries. This letter is notifying you as an adjacent landowner of the
proposed composting facility.

APPENDIX D. 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; [phone] or
[e-mail].
Sincerely,

Jenna Jorgensen
