Also, as required in the Solid Waste Renewal permit, this section presents the closure and post-closure cost estimate revision which is due by August gt,20!6. 2.t LINER ALTERNATIVES Alternatives to the permitted liner design are proposed in order to gain flexibility in construction as certain materials meeting performance requirements become available that may be utilized in the finer construction. These alternatives are proposed for Phase l and future phases, as applicable. 2.1.1 PERMITTED LINER DESIGN The permitted composite liner design consists of a clay layer and a HDPE layer. A clay layer consisting of a geocomposite clay layer (GCL) has been previously approved as the low permeable soil component. The HDPE layer would be 60 mil or thicker to minimize puncture risk. The HDPE would be protected from site soils by the clay layer. The leachate collection system would consist of a geonet. Overlaying the leachate collection layer would be a 20 ounce/yard nonwoven filter geotextile mat. The purpose of this mat is to separate the leachate collection system and the waste. A protective soil layer will be placed on top of the geotextile mat to protect the mat and geonet from protrusions and to also provide a buffering and filtration function. The protective layer will consist of a homogenous material with an average particle size less than Vz-inch diameter, and a maximum particle size less than 1 inch diameter. 2.1.2 PROPOSED LEACHATE COLLECTION I-AYER ALTERNATIVES In order to utilize construction materials as they become available, two lateral drainage layer alternatives are presented one which includes soil operations layer, geotextiles and $ravel, while the second consisting of only a thick layer of course sand. The two alternatives are described below. Detailed design and support calculations are included in the Desi$n Report portion of this document included in Section 3.0. 2.1,.2.1 ALTERNATIVE 1 Alternative 1 includes the following from bottom to top (see Figure C-501, Detail 3): o Prepared liner subgrade; Promontory Landfi ll Facility J:\Promontory Point\Permit Revision\permit Mod-Design Rpt.docx o o o r o o 2.T.2.2 GCL (non-woven); 60-MlL HDPE Geomembrane (textured on both sides); Cushion geotextile; Nine (9) inch graveldrainage layer; Non-woven geotextile filter fabric; and Minimum l8-inch protective soilcover. ALTERNATIVE 2 Alternative 2 includes the following from bottom to top (see Figure C-501, Detail 2): o o r r 2.2 Prepared liner subgrade; GCL; 60-MlL HDPE Geomembrane (textured on both sides); and Minimum 18-inch coarse sand. LINER LOW-PERMEABILITY I.AYER SUBSTITUTTON An alternative to the permitted low-permeability layer of the liner design is proposed in order to gain flexibility in construction as certain materials become available that may be utilized in the liner construction. This alternative is proposed for Phase 1 and future phases, as applicable. 2.2.1 PERM]TTED LOW-PERMEABILITY LAYER The permitted composite liner design consists of a clay layer and a HDPE layer. A clay " 2.2.2 layer consistin$ of a GCL, is presented in the permit document and is also allowed in Section ll.C of the Solid Waste Permit Renewal issued September 1, 2011 (see Appendix A). Section l].C indicates that the facility has been approved for an equivalent design which uses a geosynthetic clay liner in place of the liner required in Utah Administrative Code (UAC) R315-303-3(3XaXii). PROPOSED LOW-PERMEABILITY LAYER The low-permeability layer portion of the liner is proposed to utilize clay soils in lieu of a GCL, at the owner's option should appropriate materials become available. The clay layer will meet the prescriptive requirements of UAC R315-303-3(3)(aXii) which requires that the lower finer be constructed of at feast two feet of recompacted clay or other soil material with a permeability of no more than 1 x 10'z cm/sec. Detailed design and support calculations are included in the Design Report portion of this document included in Section 3.O. Promontory Landflll Facility Permit Modification and Design Report 2-2 J:\Promontory Point\Permit Revision\Permit Mod-Design Rpt.docx Tetra Tcch BAS 2.3 BASE GRADE MODIFICATION An alternative to the permitted base grade is proposed for stability and operational concerns. This alternative is proposed for Phase l and future phases, as applicable. It is proposed that the base grades be excavated to the maximum extent possible maintaining a five-foot seperation between the historical high level of groundwater and the bottom of the lowest liner component, along with a three percent sheet grade as opposed to the currently permitted five percent grade (see Figures C-101 and C-301). The proposed grade decrease is still within the allowed base grade in UAC R315-3033(3Xa)(ii) which allows for base grades as flat as two percent. lt is proposed that flowlines of the leachate collection pipes be greater than one percent. Detailed design and support calculations are included in the Design Report portion of this document included in Section 3.0. 2.4 LEACHATE UTILIZATION An alternative to leachate utilization is proposed. The currently permitted use/disposal of leachate is for either dust controly'compaction water on lined areas or pumped to evaporation basins. lt is proposed that the leachate may also be recirculated into the waste thus increasing anerobic digestion and landfill gas production which may be used to generate electricity. Leachate recirculation is allowed by UAC R315-303-3(2Xb) on landfills with composite liners like the PLF. Leachate recirculation would only occur in lined portions of the facility. Leachate production . 2.5 would be closely monitored to ensure that the moisture holding capacity of the refuse is not exceeded. FILLSLOPE MODIFICATION Modification of the design of the finalfill slopes is proposed. The currently permitted final fill slopes are set at 4:L (horizontal:vertical) gross or approximate 3.5:1 slopes between 1S-foot benches. The proposed modification to the final fill slopes will be gross 3:1 or 2.5:1, slopes between 1S-foot benches (see Figure C-L02). This design modification is supported by the stability analysis provided in Appendix E and disucssed in Section 3.1.4. This modification is proposed for Phase 1 and future phases, as appllicable. 2.6 ALTERNATIVE FINAL COVER DESIGN The current permitted final cover design for the PLF is as follows (from bottom to top): Permit Modification and Design Repod Promontory Landfill Facility 2-3 J:\Promontory Point\Permit Revision\Permit Mod-Design Rpt.docx fetra Toch BAS O o o o GCL; 40 MIL Very Flexibte polyethytene (VFpE); Bi-planarGeocomposite;and 18 inches of site soils. An alternative to the permitted final cover is proposed as allowed in UAC R315-303-3(4XaXi) and (ii) which allows the director to approve an alternative cover desi$n if it can be documented that the alternative cover achieves an equivalent recluction in infiltration as achieved by the standard design and the alternative finat cover provides equivalent protection from wind and water erosion as achieved by the standard design. The proposed alternative design will consist of a monolithic soil evapotranspiration cover for placement on final fill slopes which will be designed to a depth and soil type which will perform equivalently to the prescriptive standard in UAC R315-303-3(4). Detailed design and support calculations will be presented atthe time of closure when final cover materials have been selected and modeled. 2.7 CLOSURE AND POST€LOSURE MATNTENANCE COST ESTTMATE REV S ON/UPDATE As required in the Solid Waste Renewal Permit, the closure cost estimate revision/update is due by August 31, 2016. ln light of the design of phase 1, the cfosure and post+losure cost estimates have been updated from 2008 to 2eI6 rates and reflects the costs of placement of the proposed alternative final cover on the final fillslopes and the prescriptive cover on the deck areas. The post-closure costs reflect the appropriate maintenance costs for each final cover type. The cost estimates assume that closure activities would be implemented as each phase within the disposal site is completed. These closure activities would minimize the need for further maintenance, and minimize or eliminate the threat to human health and the environment from post-closure escape of solid waste constituents, leachate, contaminated run-off or waste decomposition products to the ground, groundwater, surface water or the atmosphere. The previous cost estimate prepared as part of the permit application assumed the first module to close to be 20 acres. The redesign of the landfittdevelopment provides for the initial phase to consist of 31 acres; therefore the cost estimates are based on closure of the first 31 acres of the PLF. Table A and B presents the revised/updated costs, and supporting documentation is included in Appendix G. The closure and postclosure costs have been prepared as required by UAC R315-3Og-2 and in accordance with UAC R315-309-2(3Xa) and (b). Permit Modification and Design Report 2-4 J:\Promontory Point\permit Revision\perma Mo&Design Rpt.docx Totra Tech BAS 3.0 PHASE 1. DESIGN This section describes the design and proposed construction of Phase 1 which meets the desi$n requirements of UAC R315-303 for Class I tandfilts as weff as the Sotid Waste permit Renewal conditions for the PLF. Design elements include the liner design configuration, design criteria and supporting calculations. Construction design elements include the excavation, subgrade preparation, composite liner system, leachate collection and removal system (LCRS), operations layer, and surface water drainage control system. In addition, this section summarizes the cQA plan and operational requirements for phase 1. 3,1 DEStcN 3.1.1 LINER CONF GURATION The Phase 1 development area will be the initial phase in the development of the pLF (see Figure C-100). The limits of disturbance for the Phase area is approximately 43 ! acres, of which approximately 34 acres are to be lined. Within this configuration, the ffoor area consists of approximately 26.6 acres and the slopes 4.2 acres. The liner plans for Phase 1 is shown on C-101, C-103 and G105 of the Construction plans (Appendix B). The base of Phase 1 is designed at a minimum three (3) percent sheet flow gradient and the LCRS mainline is at two (2) percent. Subgrade elevations were set to maintain positive gravity flow of liquids through the LCRS to the sump. A pump will be installed in the sump and leachate will be pumped into tanks located to the south west of the cell. The excavation slopes are comprised of a maximum of 3:1 (horizontal:vertical) slope grades. 3.1.2 DESIGN CRTTERIA The Phase 1 liner system reflects current design criteria requirements in UAC R31S303-3(3). These criteria are discussed in the following applicable construction element sections. 3.1.3 DESIGN CALCULATIONS Desi$n calculations were performed for various elements of the Phase 1 liner system. The following calculations are included in Appendix D. o Liner and LCRS Pipe Calculations: o Geotextile cushion; Permit Modification and Design Repon J:\Promontory Point\Permit Revision\permit Mod-Design r*j.?

SLOPE STABILITY ANALYSIS Analysis of slope stability is mandated for subgrade slopes by 40 cFR, part 25g.15, which requires the operator to ensure against landfilling over unstable areas which may compromise the integrity of fandfifl structural components. Final refuse fill slope stability is governed in UAC R315-302-1(2Xb). A slope stability analysis, which was based on sit+specific geotechnical field investigations, proposed liner materials and calculbtions for static and pseudostatic slope stability, was prepared forthe Phase l design. The methods and results of this work are documented in a report titled Slope stability Evaluation, promontory point Landfill Cell 1, Phase 14, Ogden Utah (see Appendix E). Static and pseudostatic slope stability calculations were completed for subgrade, liner, interim fill, and final fill slope geometries for phase 1. 3.1.5 CONSTRUCTION ELEMENTS 3.1.5.1 EXCAVATION The geometry for the Phase 1 excavation is shown on Sheets c-101, c-103, and G105 of the Construction Plans (Appendix B). The excavated soils will be stockpiled onsite, used within the cell or exported. Total excavation is approximately 7g5,OOO cubic yards, see the break down by phase in Table 1. 3-6 J:\Promontory Point\Permit Revision\permit Mod-Design Rpt.docx Permit Modification and Design Report Totra Toch BAS Table 1 Earthwork Volumes Phase 3,T.5.2 Excavatlon(GY) Phase 1A 448,OOO Phase 18 228,000 Phase 1C 109,000 Total 785,000 COMPOSITE LINER For the liner construction, a composite liner system (two-layer low-permeability systems) and an LCRS are proposed, which meet the requirements specified in UAC R315-303-3(3)(a) and (b) and the Promontory Landfill LLC Class I Landfitl Permit Application document. The UAC contains design requirements for a prescriptive liner system and also allow an operator to develop and submit for approval, an alternative liner design in accordance with UAC R315-303-3(3Xb). An alternative tiner and LCRS were approved by the Utah Solid and Hazardous Waste Control Board forthe PLF which allows a GCL in lieu of the two-foot low-permeability soil layer. Dependent upon materials availability either the prescriptive low-permeability soil layer or GCL may be utilized in the composite liner construction. Appendix D contains design support calculations for the composite liner system. The calculations check the integrity of the liner material to resist puncture, shearing and tearing. Appendix D also includes calculations for the leachate collection and recovery system design. Where the ed$es of the Phase 1 composite liner system meet future liner systems of adjacent phases, the soil and geosynthetic components from each liner system will be appropriately joined and/or welded together to form a continuous liner between the phases as shown in the Construction Plans. A representative of the geosynthetic installation contractor and CQA personnel will approve the condition of the subgrade prior to plaoement o-f geosynthetic materials. The liner design consists of the side slope and bottom areas as described in the followi ng two sections. J:\Promontory Point\Permit Revision\Permit Mo&Design Rpt.docx J g.r.s.2.tside stopes The composite liner system for the slope liner section is comprised of the following (from bottom to top as shown below in Figure G501, Detail 4): o o o . o Prepared liner subgrade; Geotextile-backed GCL or two-foot low-permeability soil layer (with conductivity less than or equal to LxLtT cm/sec); a hydraulic 60-MlL HDPE Geomembrane (textured on both sides); 16 ounce cushion geotextile;and 24-inch protective soil cover. The composite liner system has been designed to prevent migration of leachate into the underlying ground and facilitate leachate collection by the LCRS. 3.7.5.2.2 Floor Areas The composite liner system for the bottom liner section (gradients less than 5:1) is comprised of the following (fiom bottom to top as shown below in Figlure C-501, Details 2 and 3): ,} o . r o r o o Prepared liner subgrade; Geotextile-backed GCL or twcfoot low-permeability soil layer (with conductivity less than or equal to 1x1O7 cm/sec); 6O-M L HDPE Geomembrane (textured on both sides); Cushion geotextile; a hydraulic Six (6) inches gravel drainage layer; Non-woven geotextile filter fabric; and 18-inch protective soil cover. Or . o r o Prepared liner subgrade; Geotextile-backed GCL or twefoot low-permeability soil layer (with conductivity less than or equal to 1x10z cm/sec); 60-MlL HDPE Geomembrane (textured on both sides);and a hydraulic 18-inch coarse sand. The composite liner system has been designed to prevent the migration of leachate into the underlying ground and facilitate leachate collection by the LCRS. The HDPE geomembrane or flexible membrane liner (FML) will be textured on the surface placed over the finished subgrade and will be overlain by geotextile. This allows the geote)dile to move above the FML without affecting the integrity of the lowPromontory Landfill Facility Permit Modmcation and Design Repon 3-8 J:\Promontory Point\Permit Revbion\Permit MoGDesign RpLdocx Tetra Tech 8AS permeability performance of the waste containment system. The floor FML will be textured on both sides to provide the highest possible friction inteface on the floor and increase the stability of the waste prism. The construction drawings contain details for anchoring of the liner materials at the top of slope. These anchors provide restraint against pull out, which is not likely to occur given the proposed uniform waste filling operation which will provide buttressing and support of the liner system. All anchor trenches shall be monitored during construction and density tests shall be completed in accordance with the CQA plan. 3.1.5.3 LEACHATE COLLECTION AND REMOVAL SYSTEM A LCRS shall be installed above the FML on the floor, bench, and slope areas. The LCRS was designed in consideration of the following criteria: o o Provide for efficient collection and removal of leachate by gravity flow; and Limit the maximum amount of hydraulic head on the primary liner to less than 12 inches. Modelingof potential leachate was performed usingthe United States Environmental Protection Agency (EPA) Hydrologic Evaluation of Landfill Performance (HELP) version 3.07. The HELP model output files for each run are included in Appendix D. The HELP Modelwas developed to provide landfilldesigners and regulators with a tool for rapid, economical screening of alternative designs. The computer program uses climatologic, soil, and design data to produce daily estimates of water movement across, into, through, and out of the landfill. To accomplish this; daily precipitation, runoff , infiltration, surface evaporation, subsurface evapotranspiration, stored soil moisture, percolation, and subsurface lateral drainage are modeled to maintain a water balance. The model utilizes daily climatic data to develop a daily water balance for up to thirty years. The HELP Model was used to evaluate and design of both base liner section options and the slope liner for conformance with regulatory requirements. Specifically, the HELP Model was used to evaluate the total head on the liner and to determine leachate generation rates for use in Oesigning and sizing the leachate pipes and storage tanks. A review of historic climatic records from nearby weather stations revealed that the largest amount of rain in one year was 33.93 inches recorded at Brigham City waste plant in 1983. The Bringham City waste plant is approximately 24 mile north east of PPL. The 33.93 inch annual rainfall was used and HELP synthetically generated precipitation for a five year period forthe intermediate condition to determine the worst Permit Modification and Design Repon Promontory Landfill Facility 3-9 J:\Promontory Point\Permit Revision\Permit Mod-Design Rpt.docx Totra Tech BAS case scenario, or highest leachate generation rate to be expected. The default weather data from Salt Lake City was used for the final condition, with 200 feet of refuse over 30 year duration to determine the range of leachate generation to be expected. The input used in the HELP to modelthe proposed liner design profile are listed in the first section of each HELP Model output file: The input listing shows layer type, thickness, and soil characteristics. The soil characteristics are default values suggested by the HELP Modelto simulate the soils to be used in the proposed design. The HDPE layer was assumed to have a pinhole density of 3 per acre and installation defect of 3 per acre, and a placement quality of "3-good". The following table summarizes the main input values and results for the various scenarios.

August 2008 Attachment 2 Run-on Run?off Controls 3.1.5.4 STORMWATER DRAINAGE CONTROL Stormwater is water that does not come into contact with the refuse. Stormwater drainage can be described as being either run{n - stormwater flows entering the developed portion of the site from adjacent undeveloped areas, or runoff - stormwater flow coming from the developed portion of the site that has not had contact with refuse, i.e. stormwater flows over native cut slopes or intermediate cover.. All stormwater that comes into contact with refuse is considered leachate and must remain within the boundaries of the landfill liner and be managed as leachate. The landfill runoff will be kept separated from the runon flows. The diversion channels are designed to handle the 2Syear,24-hour storm event. The quantity of flow expected for the run-on condition of the Phase 1 landfitl cell was determined by usingthe precipitation rainfalf depth of 2.25 inches (NOAA precipitation frequency data server Atlas 14). The Runoff Curve Number varies across the tributary area from 63 for soil type A and 88 for Wpe D soils. The areas of the various hydrologic soil types was determined using the Web Soil Survey website from the USDA. Vegetation was assumed to be poor condition desert shrub. The 48 acre tributary is divided into eastern and western. The time of concentration was calculated using Kirpich and Manning's equations for sheet flow, shallow concentrated flow and channelized flow accordingly. The peak flow generated was determined by applying the US Soil Conservation Science Technical Release 55 (TR-55) method. Details of the input parameters and model output are included in Appendix D. Table 3 shows the peak discharge generated from the runon. Table 3 2$Year, 2fiHour Peak Flow ft€k Bffirgb 8ub€rea A1(Western Run€n) 14.68 81(Eaetern Run'4n) 47.72 (o{s) The diversion channels that convey the runon around the site consist of earthen swales that are lined with an erosion control blanket. The channels were sized using Flowmaster hydraulic software from BenUey Systems Inc. The runoff from the Phase l landfillcellwill be managed through temporary drainage facilities consisting of benches, down drains, and drainage swales. Runoff from the landfill as well as the onsite facilities will be routed through the detention basin to 3-L2 J:\Promontory Point\Permit Revision\permit MoGoesign RpLdocx lGtra T€ch BAS capture sediment and pollutants prior to the stormwater discharging from the site. lf required, culverts will be placed along the access road as needed. Stormwater that collects inside of the landfill cell but does not come into contact with refuse will drain to an earthen lined pond located in the northern portion of the cell. As the landfill expands through the phases 1A, 18, and 1C the pond will be reconstructed to accommodate the runoff volume of the subsequent interim drainage conditions. The 2 year,24 hour storm event of 1".32 inches was multiplied by the tributary area to determine the size of the ponds. Figures D-2 through D4 show the various pond configurations and calculations (Appendix D). Stormwater that accumulates at the interior basin will be allowed to settle prior to pumping to site drainage facilities. 3.1.5.5 CONSTRUCTION SWPPP The draft construction stormwater pollution prevention plan (SWPPP) has been prepared for the Phase 1 landfill cell in accordance to Utah Administrative Code R317&3.9. The Utah Pollutant Discharge Elimination System (UPDES) requires construction stormwater permits for construction activities that disturb one acre or more. The permit requires submission of a Notice of Intent (NOl) by creating an account on the Utah.gov website. The construction generaf permit must be renewed annually and the online account can be used to renewthe permits. An owner or operator may submit a Notice of Termination (NOT) form at the end of the construction activity. A draft construction SWPPP is included in Appendix H. 3.1.5.6 . INDUSTR]AL SWPPP Operators of facilities that have industrial stormwater discharges are covered by the General Multi-sector Industrial Storm Water Permit. Coverage is based on the facility's Standard Industrial Classification (Sl0) code which is 4953 for Refuse Systems. The permit requires submission of a Notice of Intent (NOl) by creating an account on the Utah.gov website. The general permit cycle is for 5 years and the online account ian be used to renew the permits.

Description of potential frrgitive waste generatons and prevention and control steps Waste loads entcring the landfill must bc covercd. Promontory IffdfiU LLC will purchase containers that are equipped with covers. In the unlikely event of receiving an unc-overed Ioad, it will be stopped for corrective actions. First time violators will reccive a one-time warning. Repeat violators will be subject to increased disposal fees. Upon entering the site, w*te loads will be taken to an enclosed transfcr station. The transfer station will specifically be designed with prevcntion of fugitive wastc in mind. The transfer of waste from incoming containers cither by truck or rail will be contained within the transfer station. Incoming containers would be rernoved and loaded to onsitc haul trucks for transit and unloading at the working face. Empty containen wiU be cleancd either at the working face, inside the transfer building, or in a fenced compound bcfore being placed back into service. Waste inside tbe transfer station will be picked up daily with though cleaning conductcd weekly. The closest weather station to Promontroy landfill sits atop thc mountain above the landfill. Per Dr. Hohnc Horel of the Departnent of Metcorolgy at the University of Utah, the wind data generated frome this weather station is not necessarily representative of the conditions at the landfill site due to the difference in elevation and topo-graihy. The applicant therrfore, will construct and operate a weather station at the landfilt iitc. information fr:om the weather station will be recorded into the Daily Operating Record. From this information, the applicant will be able to ascertain what wind evlnts (velocity, duration, and direction) compromise the effectiveness of applicant's fugitive waste control rrcasures. fr-om the applicant's weather station will be initially collccted for one ycar. Within 60 of the end of the first ycar's operations, applicant will prcsent to the Eiecutive Secretary for approval a protocol outlining wind threshoids (vclociry,iuration, and direction) requiring D- ata days possible ccssation ofoperations at the tipping face. During the first year while applicant is developing is data base and protocol applicant will ygluntarily cease placing waste at the tipping face during any wind event in which ttrc following occur: r o Wind direction is from due north to due east. Wind velocity cxceeds 35 mph for 30 minures or longcr. ^AG= L-1 August 20OB PrnnntoryLarrffilllJ,C ctass t t-anctfltt Permit tr*if:il Prior to implementation of a protocol, the applicant will take necessary preventative actions to stop fugitive wastc during cessation of opcrations cause by wind events. The buffer area around the disposal area will bc given special attention, as it is the final opportunity to prevent fugitive waste from leaving the site. A five-foot high berm would be built and topped with a lS-foot high fence. The fence and berm combination would begin on the hill along the east side, wrap around thc south side of thc property and thcn run along the wcst sidc to a point where ttre property bcgins to gain significant elevation. The remainder of the property would be fenced with a Gfoot high fence. Fencing would be inspecrcd weekly and waste cleanup and repair of the fence would occur as necessary. Positive control of fugitive waste will include the cleanup of the site, including buffer arcas on a weekly basis, and afrer wind cvcnts from due north to duc east during which the tipping facc is exposcd in excess of 35 mph that last more than thirty minuas to minimizc tbc amount of wasrc rcaching the perimeter fcnce. The drivers of the haul uucks will inspect haul roads and spills will be cleaned up as reported. Spills inside the site would be cleaned up as dctected. Any waste that escapes the sirc would be collecrcd and disposed of before thc end of the next ivorking day. At the working face, frrgitive wastc will be minimized in multiple ways. First thc working face will be reduced to the smallest workable area as possible. It is anticipated the working face will be about a half acre. Next tcmporary 12' high fencing will be placed around the working face to keep fugitive waste from moving out onto the site. Other temporary fencing will be erected if necessary to contain waste on site. .AG= L-2 August2008 Pronwttory LanffillUC Pronontorvta iltil FacilN C/ass I landfill Permit &plicalion Emergency Opentions Plan APPENDX N - EMERGENCY OPERATIONS PLAII This document provides landfill employees with infomration on how to respond and what to expect in the case of a major disaster, such as an earthquake. The Promontory Landfill Facility (hereafter refened to as the Facility), in an effort to respond to various disasters that could seriously tlueaten lives and property, has developed this Emergency Operations Plan. This Plan in not meant as a stand-alone plan; the intent is to usc this plan in conjunction with State, County, and Local Emergency Operations Plans. The Dcpartment of Environmental Quatity may elect to waive requiremens for daily cover on constnrction and demolition materials duing an emergency. ASSIJMPTIONS l. The Facility is expected to continue normal operation and must maintain normal daily operation besides handling the disposal of emergency, nonhazardous rubble material. Because of the location of the Facility and the types of structures Iocated on the premises, the Facility is expected to be minirnally affected by most major disasters. 2. The Facility will be most heavily impacted approximately 72-hours after an emergency, when the clean up, removal and disposal of rubble begins. The Facility may then need to be open amund the clock (24-hour operation). All the Facility personnel and equipment will be needed to run the operation. 3. of The primary responsibility of Landfill resources would be the Rail Transfer Area/Landfi ll operations. FIRST RESPONSE D{.'RING WORKING HOTJRS l. Remain calm and rcassure others. Avoid objects that could fall. Do not touch downed power lines or objects touching downed power lines. Ihis is especially significant at the Landfill. 2. Report your location, physical condition, and area damage to your supervisor. 3. Provided the Facility areas are not severely damaged or inaccessible, continue with normal duties. In the event that certain areas are severely damaged, perform other duties as assigned by the Supervisor. 4. The Supervisor should check all areas for structure damage and also check on site utilities. If necessary, turn these utilities off. Call the Weber and Box Elder County dispatch at (801) 399-841I and (435) 734-38W to report findings. ^AGA N-1 August 2008 Prcmontory LandfrllLLC Promontow Latrdftll FaciliV Class I Landfill Permit Apdiation Enn rgency OPe rettion s P la n 5. All efforts will be made to contact Facility employees' families and others that employees have listed on the Family Notification List. Employees will be notified of family stafts as soon as possible. AFTER WORKING HOURS l. Contact the Facility and gve your location, status, and availability. unable to get to the Landfill notify the supervisor. 2. The first person to arrive at the Landfill should check dl structures for damage and check utilities (power, sewer, gas and water) lines. If necessary, turn these If you are off. 3. After all strctures and utilities have been inspected, perform normal duties unless otherwise assigned by the Supervisor. 4. The Supervisor should check all areas for struchrre damage and also check on site utilities. If necessary, turn these utilities off. Call the Weber and Box Elder County dispatch at (801) 399-8411 and (435) 73+38ffi to report findings. FACIUTY OPERATIONS 1. The Landfill will maintain regularly scheduled working hours. 2. When the emergency cleanup begins, approximately 72-hours later, the Facility may need to be open 24-hours per day. 3. When 24-hour operation begins, all Facility personnel and equiprnent will be needed to run the Rail Transfer Area and l-andfill operations. 4. During the clean up and disposal of rubble, City/County and State Health DeparEnent inspectors will need to be at the clean-up site to determine if the substance being disposed of contains hazardous material. If so determined, then the goveming authorities (federal, state or local) must arnnge for proper disposal at a designated hazardous waste disposal facility (not the Promontory Landfill Facility). 5. During 24-hour operation employees should expect to work l2-hour shifu. Management will decide which employees take the first shift and which employees take the second shift according to ernployee availability. ^AGA N-2 August 2008 RAI{DOM INSPECTION FORM Time:_ Date: Inspected by Load Origin: How was the inspection conducted?

Listed below are monitoring guidelines for groundwater monitoring, leachate monitoring and control system, and landfill gas monitoring system. 1. Groundwater Monitoring System Background concentrations of the constituents will be established using a statistical analysis method approved by the Executive Secretary. Eight independent samples will be obtained and analyzed during the first year immediately after the permit is issued and prior to the receipt of MSW from the up gradient and down gradient wells. After background concentrations have been determined, groundwater monitoring would be conducted semi-annually in the spring and fallfrom the up-gradient and down-gradient wells. The well locations and a typical well design are shown in the attached Figure l-L,l-2,1-3, and l-4. Groundwater samples will be analyzed detection of constituents per the Utah State Administrative Code R315-308 Ground Water Monitoring Requirements.

The water samples would be collected using currently accepted and approved techniques and technologies. The protocols for sampling would consist of water level measurements, detection of immiscible layers, well purging, field measurements, sample collection, sample handling and preservation, and sample custody. Samples would be tested using a state certified laboratory. Each sampling protocol is discussed'in detail below. Water level measurements would be read to the nearest 0.O1foot. Elevations at each well would be known for cross-references and determination of ground water levels in the area. Measurements would be taken from the same location at each well. Detection of immiscible layers would begin with screening organic vapors with a monitor prior to any evacuation of water. lf concentrations were to exceed 25 percent of the lower explosive limit, landfill personnel would immediately contact the Landfill Manager. lf concentrations were betow 25 percent of the lower explosive limit, an interface probe would be lowered into the well to detect and measure the thickness of any possible immiscible layer that may develop. The probe would further be lowered to the bottom of the well to register the presence of any dense organic liquids. lf any immiscible layers were found, samples would carefully be retrieved. . The water level and interface probes will be cleaned prior to use and between each sampling point by washing with soapy (Alconoxo) water solution; spraying de-ionized water on the outside surfaces; and wiping the outside surface with a paper towel. Each well would be equipped with a dedicated low flow pump designed to be non-aerating or non-leaching. In preparation.for taking water samples, each monitoring well would be micro:purged to obtain a fresh sample. Micropurging of a well would be performed by removing water from the well using the low flow pump. when purging a well, purging would continue until the pH, conductivity, turbidity, and water temperature have stabilized or until t at least three wellvolumes of waterwould be purged from the well. Stabilization would occur when pH, conductivity, turbidity, and water temperature readings do not exceed 10 percent deviation over at least three measurements. lf the well is purged dry, samples will be taken as soon as a sufficient volume of ground water has entered the well. Field measurernent samples would be collected in a clean beaker once the well was properly purged' All probes or instruments would be kept in designated containers to prevent cross contamination between samples. All instruments would be cleaned according to manufacturer's recommendations after and prior to taking any measurements. The dedicated pumps will likely be powered by a gas-powered generator. care will be taken during sampling to ensure that the generator is located downwind of the sampling area to prevent contamination from the generator exhaust. Field measurements and field notes would include: ,\' . name of collector r time of sample . . weatherconditions . air temperature o date of sample . monitoring well identification number . lower explosive limit o immiscible layers found with thickness information . static water level . water temperature o turbidity o elecricalconductivity .pH o dissolved oxygen o wellyield o sampling procedures and methods . sampling identification number preservatives used t_ a containers used a parameters requested a daily instrument drift general comments section. This information would be recorded on the water Sample Worksheet (included at the end of this document) and kept in a field notebook. All measurement instruments would be calibrated at the beginning of the day and reghecked after all the sampling was complete to record any possible instrument drift. The pumping rate shall not exceed 100 millimeter/minute. The degree of sensitivity to pH or volatilization would determine the order in which parameters are sampled. Sampling containers and procedures for preparations of samples would be provided by the testing laboratory. Quality assurance samples will include, but not be limited to a trip blank, field blank, and field duplicates. The trip blank will be a vial of reagent grade water included in each cooler during sampling and shipping. This blank is used to provide an indication of contamination introduced as a consequence of the sampling and shipping procedure. The field blank will be a vial of reagent grade water filled in the field along with other samples taken at a selected well. This blank is used to provide an indication of contamination induced during the sampling process. Field duplicates will be collected at a rate of 10 percent. lf fewer than 10 samples are collected one field duplicate will be included. Once the samples were cotlected and prepared to laboratories recommendations, the sample would be immediately labeled, recorded in the field book, and ptaced in a sampling cooler. The samples would be recorded on a chain-of-custody and remain with the sampler untilformally released to another individual. custody of the samples would be documented on a chain of custody form. samples would remain in the custody of the sampler until samples are checked in and relinquished to the laboratory or untilthey were relinquished for transport to the laboratory. I t All data received would be reviewed to assess data validity. Each data report would be checked to insure the following: r o e . o o o ldentification numbers of the samples match. chain of custody and field notes matches the sample information. Sample analysis was performed using requested methods and acceptable time limits. Reporting limits conform to current detection limits. Blank results have been included and are acceptabte. MS/MSD results are representative and are included. All AA/aC sampling results are included and acceptable. lf there were any potential problems with the data reports or discrepancies, the laboratory would be notified immediately. lf necessary, new samples would be collected and tested. Data would be analyzed by: o Concentrations of naturally occurring constituents would be plotted at each we1 on control charts for that specific well. Each constituent would be analyzed to determine whether groundwater is being impacted. r Look for the presence of non-naturally occurring compounds. lf these compounds were reported, the validity of the results would be reviewed. lf results appear to be potentially valid, new samples would be collected and tested. Semi-annual reports would be prepared and would include the following in an electronic format: r Description of procedures, including the quality assurance/quality control, followed during the collection of samples. o o Results of field measured parameters. Chain of custody and quality assurance/quality control procedures followed by the laboratory. o r Laboratory results with detection limits and testing methods used. Statistical analysis of the laboratory results. After background constituent and levels have been established, the Owner would determine what statistical method would be used to determine whether a significant change has occurred L compared to the background water quality. ( 2. Leachate Monitoring and Control System The proposed Class I Landfilf would be equipped with a leachate monitoring and controlsystem. The system is comprised of a network of piping providing gravity flow to centrally tocated su mps positioned at the lowest elevation of the cell. The sumps would be activated if more than one foot of standing leachate is detected above the liner. The leachate would be pumped at a low flow rate to an evaporation basin or sprayed back on the surface ofthe landfill to suppress fugitive dust. Evaporation basins would accommodate peak flows. lf the evaporation basins were unable to meet the demand generated by the leachate collection system, additional evaporation basins would be constructed. 3. Landfill Gas Monitoring System Rule R315-303 Landfilling Standards require landfill gases to be monitored to protect air quality and limit explosive gas emissions. A hand-held field explosive gas meter woutd be used for recording at the site. The meter would be calibrated as recommended by the manufacture by using a methane standard. Concentrations would not be allowed to exceed 25% of the lower limit in facifity structures and 1:oo% of the lower timit around the disposat area boundary. Quarterly monitoring would be performed at the locations indicated on Figure 4.5 and within all facility structures. Readings would be taken at the ground level. lf a monitoring event were to exceed the regulatory limit, procedures would be taken as noted in section 5.2 I Water Sampling Worksheet Site Sample Date : Sample ID : Sample l-l crounowater Icrau Well Drilled Depth ft.

Comments: I Attachment 5 Closure Past-Closure 2.3 BASE GRADE MODIFICATION An alternative to the permitted base grade is proposed for stability and operational concerns. This alternative is proposed for Phase and future phases, as applicable. It is proposed that the base grades be excavated to the maximum extent possible l maintaining a five'foot seperation between the historical high levet of groundwater and the bottom of the lowest liner component, along with a three percent sheet grade as opposed to the currently permitted five percent grade (see Figures C-101and C-301). The proposed grade decrease is stillwithin the allowed base grade in UAC R315-3033(3XaXii) which allows for base grades as flat" as two percent. lt is proposed that flowlines of the leachate collection pipes be greater than one percent. Detailed design and support cafculations are included in the Design Report portion of this document included in Section 3.0. 2.4 LEACHATE UTILIZATION An alternativeto leachate utilization is proposed. The currently permitted use/disposal of leachate is for either dust contro/compaction water on lined areas or pumped to evaporation basins. lt is proposed that the leachate may also be recirculated into the waste thus increasing anerobic digestion and landfill gas production which may be to generate electricity. Leachate recirculation is allowed by UAC R315'303-3(2Xb) on landfills with composite liners like the PLF. Leachate recirculation would only occur in lined portions of the facility. Leachate production used would be closely monitored to ensure that the moisture hotding capacrty of the refuse is not exceeded. 2.5 FILL SLOPE MODIFICATION Modification of the design of the final fill slopes is proposed, The currently permitted finalfill slopes are set at 4:1 (horizontat:vertical) gross or approximate 3.5:1 stopes between ls-foot benches. The proposed modification to the final fill slopes will be gross 3:1 or 2.5:t slopes between lS-foot benches (see Figure C-LO2). This design modification is supported by the stability analysis provided in Appendix E and disucssed in Section 3.1".4. This modification is proposed for Phase 1 and future phases, as appllicable. 2.6 ALTERNATIVE FIML COVER DESIGN The current permitted final cover design for the PLF is as follows (from bottom to top): Promontory Landfi ll Facility Permit Modification and Design Repon 2-3 J:\Promontory Point\Permit Revision\permit MoGDesign Rpldocx TotraTsch BAS . . o GCL; 40 MIL Very Flexible Polyethylene (VFPE); Bi-planar Geocomposite; and 18 inches of site soils. An alternative to the permitted final cover is proposed as allowed in UAC R315-303-3(4XaXi) and (ii) which allows the director to approve an alternative cover design if it can be documented that the alternative cover achieves an equivalent reduction in infiltration as achieved by the standard design and the alternative final cover provides equivalent protection from wind and water erosion as achieved by the standard design. The proposed alternative design will consist of a monolithic soil evapotranspiration cQver for placement on final fill slopes which will be designed to a depth and soil type which will perform equivalently to the prescriptive standard in UAC R315-303-3(4). Detailed design and support calculations will be presented at the time of closure when final cover materials have been selected and modeled. 2.7 CLOSURE AND POST-CLOSURE MATNTEMNCE @ST ESTTMATE REVIS ON/UPDATE As required in the Solid Waste Renewal Permit, the closure cost estimate revision/update is due by August 3L,20!6. In light of the design of Phase 1, the closure and post-closure cost estimates have been updated from 2008 to 2016 rates and reflects the costs of placement of the proposed alternative final cover on the final fill slopes and the prescriptive cover on the deck areas. The post+losure costs reflect the appropriate maintenance costs for each final cover type. The cost estimates assume that cfosure activities woutd be implemented as each phase within the disposalsite is completed. These closure activities would minimize the need for further maintenance, and minimize or eliminate the threat to human health and the environment from post+losure escape of solid waste constituents, leachate, contaminated run-off or waste decomposition products to the ground, groundwater, surface water or the atmosphere. The previous cost estimate prepared as part of the permit application assumed the first module to close to be 20 acres. The redesign of the landfill development provides for the initial phase to consist of 31 acres; therefore the cost estimates are based on closure of the first 31 acres of the PLF. Table A and B presents the revised/updated costs, and supporting documentation is included in Appendix G. The closure and postclosure costs have been prepared as required by UAC R315-309-2 and in accordance with UAC R315-3O9-2(3)(a) anct (b). 2-4 J:\Promontory Point\Permit Revision\permit Mod-Des(n Rptdocx Totra Tech BAS TABLE A PROMONTORY TANDFILL LLC PRELIMIMRY CLOSURE COST ESTIMATE a ru,covBblllzation/Demobillzati 1_ liminary Grading/Sub! t (Ileck) 1,357,000 MIL VFPE Uner (Oeck) 191,353 191,353 191,353 lglvegetative Cover 18' Thick plrdu"r 191,3s3 123,342 C"""istrp*,Ii- Monument Installation 2 :ll{at govER oot{slBucnofl Quru,ryAssuRAllcE -r 5 4.4 26.4 $si?66-' $370,025 $1,500 ls I $5O.OOO 6C $10,ofi) ac ac 2su&otat $2,100 2,500 9300.000 9g0o,0oo $9,240 $67.000 bnrffii szs:no OL 30 4 ea 30 ac ea $o $1"200 $36,000 879 $3,515 ltcm 4 Subtotat Sgg,sto DffA TASE OOiTTROL SVSTGiI $12.Oq) Itm rrRrrcruRE oIlsTRUCnOil rn lAcilEilT ,;onsutruon Management t ls 30 ac $360.OOO il RflovAl/AB xDoilnEilT )ernolition€cale House/Salvage S€bs 63 ,e@mm6$ontng ot Envtronmental control sy€tem 7 $L24.379 ;T--Goo- Itcm lydroseeding DIaloeEe Control Svstem (incl, bernB. downdmire- lnlets. etc-I50 6 30 DillSeeqing Ylonitoring and Control SElems ''o lalse LFG Well Heads tynth€uc Boots (D€ck) E $153,OE2 $0.5"0 gnosDr @rrnot (newogrenol)'" 4 $200,000 $135,700 $143,515 $2O0,O00 - lilonitoring lrcp€ctlng, Testing and Reporting 3 ls ;-f $oro $o?5 sf $0.8o "-f rrTjoss ?T $po tT s960,000 $50,000 $50,000 $0 $12.OOO $360.000 m TOTALPREUMINANY cLosuRE cosr se42g3ct Footnotes*: 1.O Assumes all soil necessary for do$rre is stockpiled on site. 1.1 Includes noc€€sary permits, health & safety plan, swPPP, bid bond, office equlpment, traller, ufllities, ofrtce support, goneral labor, and miscellaneous charges to be incurred by the cont actor.
