Other federal, state, or local agencies may have requirements that the facility must meet. The applicant is responsible to be informed of, and meet, any applicable requirements. Examples of these requirements may include obtaining a conditional use permit, a business license, or a storm water permit. The applicant is reminded that obtaining a permit under the Solid Waste Permitting and Management Rules does not exempt the facility from these other requirements. Please take note of the heading of each section for the facilities that the section applies to. An application for a permit to construct and operate a landfill is the documentation that the landfill will be located, designed, constructed, operated, and closed in compliance with the requirements of Utah Administrative Code R315-301 through 320 (Utah Solid Waste Permitting and Management Rules) and Utah Code Annotated 19-6-101 through 126 (Utah Solid and Hazardous Waste Act). The application should be written to be understandable by regulatory agencies, landfill operators, and the general public. The application should also be written so that the landfill operator, after reading it, will be able to operate the landfill according to the requirements with a minimum of additional training. Copies of the Solid Waste Permitting and Management Rules, the Utah Solid and Hazardous Waste Act, along with many other useful guidance documents can be obtained by contacting the Division of Waste Management and Radiation Control at 801-536-0200.

The facility is divided into areas for waste processing, waste disposal, and storage of recyclable materials. The waste disposal area, which is approximately the westerly half of the property, receives waste that is then segregated for either recycling or disposal. Materials are initially processed to separate recyclable materials from disposal materials. Once segregated, the recyclable materials are stockpiled and further processed in the materials storage area, and the disposal materials are deposited in the waste disposal area. The materials for disposal may include but are not limited to asphalt mixed with concrete, trees, signs, fencing material, etc. The disposal area is graded and covered with soil on an as-needed basis. The processing areas and disposal areas are rotated within the footprint of the disposal area to provide uniform disposal and level working areas. Soil for the cover material is select waste that is obtained from the waste stream and stockpiled at the north edge of the waste disposal area. Topsoil for the final closure is also stockpiled on the north side of the disposal area. The materials storage area is approximately the easterly half of the property. Materials stockpiling is typically recyclable materials, which can include clean fill, concrete, and asphalt. Concrete and asphalt are crushed and incorporated into common fill, base course materials, or hot mix asphalt for construction projects. See the facility plans in Appendix A for an overview of the facility layout. Stormwater storage is provided in shallow basins at the east side of the waste disposal area and along the southerly edge of the recyclable materials storage ar ea. Surface grading directs stormwater runoff to the retention areas. Additional stormwater retention areas will be added as indicated on the facility drawing. Recent updates to the landfill plans have limited the disposal of non -recyclable materials to the west side of the site. This is consistent with previous waste disposal patterns and future plans for the property. The closure plan has been updated to show a smaller waste disposal area and a greater height. The closure plan maintains an anticipated total waste volume of 300,000 cubic yards. Advanced Paving and Construction Class IVb Landfill Permit Renewal Application 2023 5 1.2 - LEGAL DESCRIPTION OF THE FACILITY (R315-310- 3(1)(c)) Property Serial Number: 15-064-0041 Size: 21.25 acres Legal Description dated 5/26/98: Part of the southwest quarter of Section 24, Township 6 North, Range 2 West, Salt Lake Base and Meridian, US Survey: Beginning at a point 17.61 chains north and 231.84 feet west from the southeast corner of said quarter section, running thence north 326.5 feet; thence North 32d30' West 513.51 feet; thence West 509.25 feet, thence South 26d30' West 33 feet, more or less, thence North 88d22' 38" West 701.53 feet; thence South 11d03' 39" East 659.08 feet, more or less, thence South 75d39'39" East 216.64 feet; thence South 71d09'39" East 80.40 feet; thence South 85d41'39" East 110.9 feet; thence North 89d34' 21" East 131.75 feet; thence east to the point of beginning. Together with right -of- way (1427-483) 1.3 - LAND USE AGREEMENT (R315-310- 3(1)(c)) The landfill property is owned by Weber Properties, LLC. Advanced Paving and Construction has been granted use of the property for a landfill by an agreement with Weber Properties, LLC. Under the terms of this agreement, Advanced Paving and Construction has sole responsibility for the maintenance and operation of this facility. A copy of the agreement between Advanced Paving and Construction and Weber Properties, LLC is included in Appendix B. 1.4 - DEMONSTRATION THAT THE LANDFILL IS NOT A COMMERCIAL FACILITY Advanced Paving and Construction uses this facility for its own use and does not intend to operate this facility as a commercial landfill. Access to the facility is controlled through two (2) locked gates. These gates are only open when Advanced Paving and Construction employees are present and access to the landfill area is required. Entry is further controlled by visual inspection, as vehicles must pass in front of the Advanced Paving and Construction office building to access the landfill area. 1.5 - WASTE TYPE AND VOLUME (R315-310- 3(1)(d)) Waste stored and disposed of at this facility is construction/demolition waste, yard waste, and inert waste generated during the course of business for Advanced Paving and Construction. Accepted waste materials comply with R315-301-2(7) and may include, but are not limited to, soil, concrete, asphalt, fencing, building demolition, and metal (i.e. rebar, steel Advanced Paving and Construction Class IVb Landfill Permit Renewal Application 2023 6 beams, general building debris). The amount of waste delivered to the landfill over the past five years has averaged less than 1,000 cubic yards per year. It is anticipated that the amount of waste delivered to the site will increase in the future. Nearly all the waste disposed of in this landfill is generated from construction projects located within a 30 -mile radius of the landfill site. 1.6 - LOCATION STANDARDS (R315-310- 4(1)) This landfill is an existing facility and is not subject to the location standards given in R315-305-4 and R315-302-1. 2.0 - PLAN OF OPERATION 2.1 - SCHEDULE OF CONSTRUCTION (R315-302- 2(2)(a)) The landfill is an existing facility, and all basic components of the facility have been constructed. 2.2 - DESCRIPTION OF ON-SITE WASTE HANDLING PROCEDURES (R315-302- 2(2)(b) and R315- 310- 3(1)(f)) This facility is open only to Advanced Paving and Construction employees, and on-site waste handling is controlled through employee meetings. All employees are informed about which waste materials are acceptable for disposal, and areas of the landfill are to receive specific types of waste material. Additionally, management personnel visits to the landfill area are performed on a regular basis to observe that proper storage and disposal procedures are being followed. The volume of materials delivered to the landfill is tracked by means of a daily load count. A copy of the daily load count form is provided in Appendix C. Daily load count records are maintained for inspection at the office of Advanced Paving and Construction. 2.3 - SCHEDULE OF INSPECTIONS AND MONITORING (R315-302-2(2)(c) and R315-310-3(1)(g)) Inspections of the landfill facility are conducted not less than quarterly. The form used for recording inspection observations is provided in Appendix C. In addition to the quarterly inspections, management personnel regularly observe the facility to ensure that proper procedures are being followed. Any deviations from appropriate procedures are immediately corrected. Advanced Paving and Construction Class IVb Landfill Permit Renewal Application 2023 7 2.4 - CONTINGENCY PLANS IN THE EVENT OF FIRE OR EXPLOSION (R315-302- 2(2)(d)) The risk of a fire or explosion at this landfill is minimized by not allowing decomposable waste such as household, restaurant, food processing, and commercial waste. Advanced Paving and Construction employees are prepared to provide immediate fire suppression in the event of a waste fire. Fire suppression will be accomplished by means of earth-moving equipment when possible. If necessary, water may also be used to extinguish fires. The on -site stormwater retention pond is equipped with a portable 6-inch diameter pump that may be used to provide water for fire suppression. In the event of an uncontrolled fire or a fire that cannot be managed by on-site personnel, the Weber County Fire Department will be contacted. The Fire Department is located approximately 4 miles from the facility; the estimated response time is 10 minutes. On arrival at the facility, Fire Department personnel will assume responsibility for fire abatement activities. 2.5 - CORRECTIVE ACTION PROGRAMS FOR GROUNDWATER CONTAMINATION (R315-302- 2(2)(e)) The possibility of groundwater contamination is minimal because disposal of hazardous materials is not permitted at this facility. In the unlikely event that groundwater does become contaminated, Advanced Paving and Construction will retain a qualified professional to define the extent of the problem, develop a plan for corrective action, and implement the plan. The Utah Division of Solid and Hazardous Waste will be notified if groundwater contamination is observed or suspected. 2.6 - CONTINGENCY PLANS FOR OTHER RELEASES (R315-302- 2(2)(f)) The possibility of releasing explosive gases from the landfill is minimal because disposal of decomposable waste is not permitted at this facility, and the materials that are accepted have a very low potential for generating explosive gases. Failure of the runoff containment system is not a significant possibility because the site is graded to direct runoff toward the low point at the center of the facility. The low point of the facility is much lower than the surrounding area, and this low area creates a storage volume that is many times the potential runoff volume for the facility. Waste materials that are likely to be transported by the wind will be covered the day they are delivered to the site. The site will be frequently monitored for litter, and any litter that is observed will be collected and covered. 2.7 - PLAN TO CONTROL FUGITIVE DUST AND COVERING OF WASTE (R315 -302- 2(2)(F)) Vehicles traveling on the access road to the waste disposal site have the highest potential for generating fugitive dust. Dust from the road has been minimized by covering it Advanced Paving and Construction Class IVb Landfill Permit Renewal Application 2023 8 with roto-milled asphalt (1" minus asphalt, recycled from existing roadways). Roto -milled asphalt material covers the roadway and eliminates problems associated with dust. The roadway surface has also been covered with a chip and seal coat to further protect the road surface. Within the landfill area, water trucks are used to prevent dust problems by wetting the ground surface. Waste piles are regularly pushed off with a bulldozer and covered with soil. As excavated soil is the most common type of material disposed of within this facility, material for covering the waste is readily available. Additionally, topsoil is being stockpiled, which may be used in the future to cover the site for final closure. If necessary, dust control as waste piles are pushed off is accomplished using a water truck. 2.8 - DESCRIPTION OF MAINTENANCE OF INSTALLED EQUIPMENT (R315 -302- 2(2)h)) This facility does not contain a leachate collection system, gas collection system, groundwater monitoring equipment, or any other installed equipment. 2.9 - PROCEDURES FOR EXCLUDING THE RECEIPT OF HAZARDOUS OR PCB WASTE (R315-302- 2(2)(I)) Hazardous materials or materials containing PCBs are excluded from this facility by limiting facility access for waste delivery to only Advanced Paving and Construction employees and allowing only materials from Advanced Paving and Construction 's construction sites. Acceptable materials for disposal at the landfill facility are identified at the construction site. If any hazardous or otherwise unacceptable waste materials are identified on a construction site, they are properly disposed of at a facility that is permitted to receive this waste. Hazardous waste materials identified on an Advanced Paving and Construction job site must be handled and delivered for disposal by either another contractor or the site owner. Advanced Paving and Construction does not have the certifications necessary to handle and haul hazardous wastes. 2.10 - PROCEDURES FOR CONTROLLING DISEASE VECTORS (R315-302- 2(2)(j)) Controlling disease vectors is accomplished by eliminating the habitat attractive to rodents. Non-recyclable wastes are regularly covered to stop potential nesting areas for rodents or other undesirable types of animal life. Breeding grounds for insects are minimized by avoiding grading that creates shallow pools of water. If areas of stagnant water are observed, these areas are graded to promote drainage. The pond used to contain runoff near the center of the facility is relatively deep and has not caused insect problems in the past. 2.11 - PLAN FOR ALTERNATIVE WASTE HANDLING (R315-302- 2(2)(k)) Conditions that would prevent this facility from accepting waste are unlikely because Advanced Paving and Construction Class IVb Landfill Permit Renewal Application 2023 9 there is no permanent equipment on-site. Equipment necessary for grading, covering, and processing waste material is brought to the site as needed. This equipment could be rented from a number of sources if breakdowns were to occur. If a condition preventing the facility from accepting waste does occur, waste would be taken to another acceptable facility. Weber County C & D Landfill, which is located approximately 11 miles away, is a potential alternate location for waste disposal. 2.12 - GENERAL TRAINING AND SAFETY PLAN FOR OPERATIONS (R315-302- 2(2)(n)) The safety and operation of this facility are covered under the safety plan for Advanced Paving and Construction. Training for Advanced Paving and Construction employees will also include information from this document. 2.13 - RECYCLING PROGRAM (R315-302- 2(2)(n)) The facility is used for the processing and storage of recyclable materials and the disposal of non-recyclable materials. Recyclable materials delivered to the site include soil and asphalt paving materials. Recyclable materials are initially segregated in the waste disposal area and then moved to the storage area on the east side of the property. Concrete and asphalt materials are crushed for use for reuse in hot mix asphalt, roadbase, and common fill materials. Stockpiles of asphalt and concrete materials are maintained in the storage area until needed for roadway construction materials. Advanced Paving and Construction Class IVb Landfill Permit Renewal Application 2023 10 PART III TECHNICAL REPORT 3.0 - MAPS See the attached maps in Appendix A. 4.0 - ENGINEERING REPORT 4.1 - CELL DESIGN AND FILL METHODS (R315-310- 3(1)(b)) This facility is located on a parcel that is approximately 21.2 acres. The waste disposal site occupies approximately 7.5 acres of the parcel, materials recycling and storage occupies approximately 8.5 acres, and natural vegetation buffers (including a trail easement along the river) make up the remainder of the parcel. See the attached drawings and facility plans for an overview of the facility layout. Waste materials are generally received in the waste disposal area by material type (e.g., concrete or asphalt) and then further segregated for disposal or recycling. Recyclable materials are transferred to the materials storage area, and materials for disposal are deposited and graded within the disposal area footprint and covered as needed. The active disposal area and the materials segregation areas are rotated to maintain a more consistent waste elevation and a uniform surface for the segregation and processing area. 4.2 - DESIGN AND LOCATION OF RUN-ON AND RUNOFF CONTROL SYSTEMS (R315-310- 5(2)(b)) The landfill is located on a site that was previously mined for gravel. Prior to mining operations, the natural ground surface for most of the site was higher than the surrounding area. Gravel mining operations left a depression near the center of the property. Although the depression has been mostly filled by clean fill material, the general drainage pattern remains toward the center of the property. Runoff from the waste disposal and materials storage areas is contained in on-site retention basins. The existing drainage pattern will be maintained by grading as waste materials are placed at the site. As the site is filled with waste, drainage ditches, and channels will be created to maintain the desired drainage pattern . Additional runoff retention areas will be created along the west side of the fill area. Runoff volumes were calculated separately for the waste disposal area and the materials storage area. Currently, the runoff from both areas is tributary to the low area s near the west and south edges of the materials storage area. At closure, the runoff will be retained in separate areas. For current conditions, a total potential runoff volume of 1.6 acre-feet was Advanced Paving and Construction Class IVb Landfill Permit Renewal Application 2023 11 calculated for the 25-year, 24-hour storm event. Runoff volumes were calculated using the National Resource Conservation Service (NRCS) curve number methodology, and calculations are provided in Appendix D. The existing stormwater retention area has a storage volume greater than 2 acre-feet. As materials storage and disposal operations expand, the site will be graded so a stormwater retention volume of at least 1.6 acre-feet is maintained. When the landfill approaches capacity, the stormwater retention area will be moved to the west and east edges of the disposal site. The required retention volume will decrease to 0.13 acre-feet for the 25-year, 24-hour storm event when the final closure is constructed, and vegetation is established in the landfill area. This retention volume is for the landfill waste disposal area. It has been assumed that the materials storage and processing area will continue as industrial land use following final closure, and runoff from this area will be regulated by a discharge permit or by the Marriott- Slaterville stormwater management plan requirements. 5.0 - CLOSURE PLAN 5.1 - CLOSURE SCHEDULE (R315-310- 4(2)(d)(i)) It is anticipated that with proper management and continued recycling of asphalt material, this landfill may be operated in excess of 20 years. At the proposed final closure elevation, this site could receive approximately 300,000 cubic yards of material. At this time , the landfill is approximately 33% full, leaving approximately 200,000 cubic yards of available capacity. In the past five years, the landfill received less than 1,000 cubic yards of waste material per year. It is likely that Advanced Paving and Construction's business will continue to grow, and the rate of material coming into the site will increase. If the amount of material brought to the site for disposal increases to an average of 10,000 cubic yards per year or approximately 18,000 tons per year, the landfill will approach its design capacity in approximately 20 years. 5.2 - DESIGN OF FINAL CLOSURE (R315-310- 4(2)(c)(iii) and R315-305-5(5)) At final closure, the landfill will be closed as per applicable requirements with the State of Utah, Weber County, and Marriott-Slaterville City. Prior to placing the final cover layer, the site will be graded and leveled to create a smoothly contoured area. The landfill cover will consist of a layer of clean soil at least 2 feet thick over the top of the waste. Excess soil excavated from Advanced Paving and Construction's construction projects is a large portion of the material delivered to this landfill, and the cover material will be obtained from the soil delivered to the landfill. The 2-foot thick layer will include an upper layer of topsoil at least 6 inches thick. Topsoil will be stockpiled on-site for future use during closure. The final cover will be seeded with shallow-rooted vegetation and a seed mix similar to native grasses. The Advanced Paving and Construction Class IVb Landfill Permit Renewal Application 2023 12 proposed seed mix is shown in the maps in Appendix A. Final grading contours and a typical cross-section are shown on the attached drawings. The maximum elevation of the final cover is approximately 36 feet above the existing ground surface. Advanced Paving and Construction is planning to use and maintain the landfill area after landfill closure. Parts of the landfill area may be utilized for future facilities to process roadway construction materials. 5.3 - CAPACITY OF SITE IN VOLUME AND TONNAGE (R315-310-4(2)(d)(ii)) The proposed closure grading plan provides a total landfill volume of approximately 300,000 cubic yards of material. At an average weight of 1.8 tons per cubic yard, 300,000 cubic yards equates to 540,000 tons. It is estimated that the landfill is currently 33% filled, which leaves 200,000 cubic yards or 360,000 tons of available capacity. 5.4 - FINAL INSPECTION BY REGULATORY AGENCIES (R315-310-4(2)(d)(iii)) Final closure of the facility will be conducted as per regulation R315-302-3(4)). This will include notification to the Executive Secretary that closure of this facility is intended as well as notification and appropriate documentation that closure has been completed. Notification will also be given to any other agency entity as may be directed (i.e., Weber County Environmental Health Department, Marriott-Slaterville City). 6.0 - POST-CLOSURE CARE PLAN (R315-310-3(1)(h)) 6.1 - SITE MONITORING (R315-310- 4(2)(e)) Groundwater and surface water monitoring and site monitoring for landfill gases are not required for a Class IVb landfill. Site monitoring associated with maintenance of cover material, vegetation, and runoff control facilities is discussed in Section 6.3. 6.2 - CHANGES TO RECORD OF TITLE, LAND USE, AND ZONING RESTRICTIONS (R315-310- 4(2)(e)(ii)) Upon closure, "plats and a statement of fact" concerning this facility will be recorded as a part of the record of title with the Weber County Recorder. At the time of closure , a determination will be made if changes to the title, land use, and zoning are required. If such action is deemed necessary, steps will be taken to ensure proper compliance with appropriate regulations. Advanced Paving and Construction Class IVb Landfill Permit Renewal Application 2023 13 6.3 - MAINTENANCE ACTIVITIES TO MAINTAIN COVER AND RUN-ON/RUNOFF CONTROL SYSTEMS (R315-310- 4(2)(e)(iii)) Maintenance activities to maintain the cover and runoff control systems will include semi-annual inspections to assess the condition of the landfill cover material, vegetation, and runoff control facilities. Any areas of erosion or significant settlement will be repaired and the area re-seeded. Maintenance of the runoff control facilities may include cleaning out the retention areas to maintain sufficient storage volume. Due to the topography of the site, run -on control facilities are not needed. 6.4 - POST CLOSURE CARE – CONTACT PERSON OR OFFICE (R315-310-4(2)(e)(iv)) Any questions or concerns during the post-closure care period should be directed to: Advanced Paving and Construction 1723 West 1350 South PO Box 12847 Ogden, Utah 84412 Telephone (801) 731-7882 7.0 - FINANCIAL ASSURANCE 7.1 - CLOSURE COSTS (R315-310- 4(2)(d)(iv)) Closure costs for this facility have been estimated to be $ 41,000.00. This cost includes the cost to complete necessary engineering requirements, place topsoil, and seed the landfill area. Closure costs are guaranteed by means of a surety bond.
