ONE TO CONTRACT WITH GC ENVIRONMENTAL, INC. FOR MAINTENANCE/REPAIR SERVICES FOR THE NEWPORT TERRACE LANDFILL GAS CONTROL SYSTEM ISSUE: Should the Council approve a contract amendment to extend GC Environmental, Inc.'s (GCE) contract for one (1) year (FY 2010 - 2011)? RECOMMENDATION: Approve Amendment No. One to the Contract with GCE in the amount of $66,206.00 for an additional one (1) year (FY 2010 -2011) of Operation, Monitoring and Maintenance (OM &M) of the Newport Terrace Landfill Gas Control System (System). BACKGROUND: On June 9, 2009, Council approved the award of the original contract for OM &M services of the System to GC Environmental, Inc. DISCUSSION: Since July 1, 2009, GCE has been the System OM &M contractor. Each month, GCE monitors and maintains the methane and sulfur gas levels of the System to fall below the SCAQMD permit requirements. Monitoring reports are generated (monthly and quarterly) and submitted to the Orange County Environmental Health Division (also known as the Orange County Solid Waste Local Enforcement Agency) (LEA) and South Coast Air Quality Management District ( SCAQMD), respectively. On April 14, 2010, representatives from the City of Newport Beach Utilities Department (City) and the Newport Condominium Association (NCA) met to discuss GCE's contract, Newport Terrace Landfill Gas Control System June 22, 2010 Page 2 which terminates on June 30, 2010. During this meeting, the City and the NCA agreed that GCE's overall performance has been outstanding. GCE's growing knowledge of the system will enable them to provide guidance to the City and the NCA on future upgrades and preventative maintenance that will help the System continue running smoothly. With concurrence from the NCA, Staff recommends extending GCE's contract for a period of one (1) year. A budget of $80,000 is needed for FY 2010 -2011 of OM &M services. A breakdown of the $80,000 budget can be found in the Funding Availability Section. Under the terms of the Settlement and License Agreement, the NCA is obligated to reimburse the City for 50% of the negotiated contract costs. Reimbursement will be accomplished by submittal of a City invoice, generated by the Revenue Department, which is done quarterly. ENVIRONMENTAL REVIEW: The project is Categorically Exempt from provisions of the California Environmental Quality Act (CEQA) pursuant to Section 15301, Class 1 of the CEQA Implementing Guidelines. This exemption covers operation, repair, maintenance, minor alteration, etc., of existing structures, facilities, mechanical equipment, etc., involving no expansion of use of that existing at the time of the City's determination. A Notice of Determination has been filed with the Orange County Clerk's Office. GEOTECHNICALISURVEY SERVICES: Not applicable. CONSTRUCTION AND PROJECT MANAGEMENT: No construction management is needed. Project management will be handled by the Utilities Department staff. FUNDING AVAILABILITY: Sufficient funds are available in the Environmental Liability, Services Professional 8 Technical, 3155 -8080, budget for this contract renewal. Should additional funds be required, Utilities will request a budget amendment through the City Manager.

AND MAINTENANCE MANUAL OBJECTIVES The City of Newport Beach (City) has entered into an agreement with Newport Condominium Association, Inc. (NCA) to operate and maintain the LFG collection and control system at the Newport Terrace Landfill. The purpose of this manual is to familiarize the reader with and to provide step -by -step instructions for the operation, maintenance, and monitoring of the Landfill Gas (LFG) control system at the Newport Terrace site. It is recommended that qualified, experienced professionals operate, maintain, and monitor the system, especially if LFG is detected at or outside the property boundary or if the system is modified significantly. It is further recommended that this manual be updated periodically to reflect the current operating conditions, such as for a change in operation, when extensive reconstruction or modifications have been made, when maintenance or monitoring events provide new information, changes in regulations, or other important events occur that may affect the monitoring regime. At a minimum, the manual should be reviewed annually to determine if modifications are needed. 1.2 APPLICABLE PERMITS AND REGULATIONS The LFG system at Newport Terrace operates under the following permits issued by the South Coast Air Quality Management District (AQMD): 1.2.1 No. F85011, Issued November 6, 2006 (Appendix C) This "Permit to ConstiucUOperate" principally addresses the LFG treatment (carbon adsorption and system, setting requirements for operation, monitoring and reporting). A summary of requirements follows. • LFG flow through the treatment system shall not exceed 375 standard cubic feet per minute (scfin). • Concentration of total non - methane organic compounds ( TNMOC) in inlet gas (before treatment) shall not exceed 250 parts per million by volume (ppmv) measured as hexane. • Concentration of TNMOC after treatment shall not exceed 20 ppmv measured as hexane at 3 percent oxygen, or shall be reduced by at least 98 percent by weight (relative to inlet concentration). • Annual source test required (see Item #10 in Permit, Appendix C). • Monthly sampling of inlet and treated gas for volatile organic compounds (methane and TNMOC) and Toxic Air Contaminants (TACs). Newport Terrace Landfill — O &M Manual • Monthly sampling of Sulfa -Treat system exhaust for sulfur compounds (as hydrogen sulfide). • Emissions at the treatment exhaust shall not exceed the following concentrations: - Chloroform 0.10 ppmv - Vinyl Chloride 0.17 ppmv - Hydrogen Sulfide 0.1 ppmv • If TNMOC concentration at the outlet of the primary (lead) adsorber exceeds 20 ppmv, the carbon in the primary adsorber shall be replaced or the vessels rotated (see Item #16 in Permit). 1.2.2 No. F85012, Issued November 2, 2006 (Appendix D) This "Permit to Construct/Operate" principally addresses the LFG collection. It sets conditions for the construction/installation of extraction wells and collection piping, principally to prevent nuisances and air quality impacts during underground construction (drilling and trenching). The Permit allows for a control system of up to 75 vertical extraction wells (the newly installed system has 15). The future construction of additional wells (if needed for additional control and/or replacement of failed wells) would need to conform to this Permit. 1.2.3 Rule 1150.1 Compliance Plan, Issued December 17, 1999 (Appendix G) AQMD Rule 1150.1 addresses surface emissions and lateral (subsurface) migration of LFG. All of the surface emissions monitoring requirements contained in Rule 1150.1 have been waived by the AQMD for the Newport Terrace site (see Appendix G). Monthly perimeter probe monitoring is required, which is duplicative of requirements under CCR Title 27 (see next section). However, the Rule 1150.1 Plan does add these requirements to the routine probe monitoring: • Obtain laboratory analyses of a gas sample from a monitoring probe: - Toxic air contaminants (TAC) from the probe with the highest concentration during any one of the monthly monitoring events during the quarter. - Total Organic Compounds (TOCs) — if the TOC concentration measured with a Flame Ionization Device or approved alternative instrument exceeds 5 percent by volume in any of the probes, a single sample from the probe with the highest concentration (from the monthly monitoring events during the quarter). 1.2.4 California Code of Regulations (CCR), Title 27 These regulations govern subsurface lateral gas migration, and are administered by the local enforcement agency (LEA), in this case the Orange County Environmental Health. 2 Newport Terrace Landfill - O &M Manual Conformance requires monthly monitoring and reporting of perimeter gas migration probes. Methane concentrations in the probes may not exceed 5 percent by volume. 1.3 SITE LOCATION AND PHYSICAL DESCRIPTION The Newport Terrace Landfill (Newport Terrace) is located at corner of Balboa Boulevard and 19th Street in the City of Newport Beach, CA (see Figure 1). The site contains the Newport Ten-ace Condominium complex that consists of 62 residential buildings containing between two to eight condominium units each, parking garages and ancillary buildings. All units are residential use and many families live in them. It is assumed that most are owner- occupied; however, some are rental units. The condominium complex was constructed at the site in 1972; prior to that, it was vacant land partially used for aggregate mining and land - filling (until 1967). A portion of the condominium complex overlies an inactive municipal solid waste (MSW) landfill, operated in the 1960's and 1970's. The landfill actually has two distinct areas: (1) the main landfill, and (2) the "rubble fill," which received principally inert waste. The areas are delineated on Figure 2. An LFG system was installed in landfill areas in the early 1980's to protect the surrounding residential improvements. A substantial reconstruction replacement of the LFG system was initiated in September 2007 and completed in May 2008. The new system consists of 15 gas extraction wells, associated underground collection piping, four pneumatic condensate traps, and an indoor treatment facility consisting of blowers, hydrogen sulfide removal and carbon adsorption equipment. The system also contains cross - connections to allow extraction from portions of the previously existing gas control system. In addition, about 40 gas migration monitoring wells (including about 80 probes) exist at the site. A complete set of as -built drawings of the reconstructed LFG system is contained in Appendix A. The new system was constructed pursuant to corrective action ordered by the Orange County Local Enforcement Agency (LEA), the California Integrated Waste Management Board (CIWMB), and permits from the South Coast Air Quality Management District (SCAQMD) Newport Terrace Landfill — O&M manual Figure 1.

The contact person for the City is: George Murdoch City of Newport Beach Utilities Department 3300 Newport Boulevard P.O. Box 1768 Newport Beach, CA 92658 -8915 (949) 644 -3011 1.5 LANDFILL GAS HAZARDS LFG is produced as part of the decomposition processes that occur following the burial of organic refuse materials. LFG contains methane which is a flammable gas — if exposed to an ignition source, methane is explosive at concentrations between 5 and 15 percent v /v, the so- called lower and upper explosive limits (LEL and UEL). An LFG mixture is flammable at higher methane concentrations. Production of LFG can create pressure within the landfill which acts as a driving force, pushing LFG into surrounding soils, which can result in off -site subsurface movement (migration). The placement of cover soil or other means of capping (i.e., pavement or landscaping) over the landfill site or adjacent areas reduces free venting of LFG to the atmosphere and promotes lateral LFG migration toward off -site locations. Methane migrating through soils from landfill sites may pose a safety threat if it is allowed to infiltrate into an enclosed space, and is ignited by a spark or other ignition source. Methane can accumulate in buildings above the ground surface, particularly in wall spaces. The distance and speed of LFG migration are functions of the rate of gas generation, characteristics of the landfill cover (which regulates internal pressure buildup), the elevation of groundwater, and the permeability of adjacent soils. The composition of the waste and the availability of moisture are the principle factors determining the amount of LFG generated. Construction debris with low organic content produces a small volume of gas, whereas municipal wastes with a high organic content can produce substantial volumes of LFG. The age of the landfill also affects the rate of gas generation. Decomposition of refuse, and the resulting gas generation, will slow over time as the organic fraction of the waste is consumed. It has been observed that significant gas production and the potential for a migration problem may proceed for 20 to 50 years after the placement of refuse in the landfill site. The LFG system at Newport Terrace was installed to control potential off -site subsurface migration. As generated, LFG is primarily composed of 45 to 60 percent methane and 40 to 55 percent carbon dioxide. In older landfills, such as Newport Terrace, the LFG is often naturally diluted Newport Terrace Landfill — O &M Manual with nitrogen and oxygen due to air intrusion into the waste mass. LFG also includes small amounts of ammonia, sulfides, hydrogen, carbon monoxide, and non- methane organic compounds (NMOCs) such as trichloroethylene, benzene, and vinyl chloride. Table 1 lists typical landfill gases, their percent by volume, and their characteristics. NMOCs consist of hazardous air pollutants (HAPs) and volatile organic compounds (VOCs), which can react with sunlight to form ground -level ozone (smog) if uncontrolled. Some of the NMOCs also are odorous. Rule 1150.1 identifies a list of specific Toxic Air Contaminants (TACs) which must be sampled for within collected and treated gas, as well as at probes (see Section 1.2.1 and 1.2.3). Table 1. Typical Landfill Gas Components Component percent by Characteristics Volume Methane 45 -60 Methane is a naturally occurring gas. It is colorless odorless, and can be explosive. Landfills are the single largest source of U.S. man -made methane emissions. Carbon Dioxide 40 -55 Carbon dioxide is naturally found at small concentrations in the atmosphere (0.03 %). It is colorless, odorless, and slightly acidic. Nitrogen 2 -5 Nitrogen comprises approximately 79% of the atmosphere. It is odorless, tasteless, and colorless. Oxygen 0.1 -1 Oxygen comprises approximately 21 % of the atmosphere. It is odorless, tasteless, and colorless. Ammonia 0.1 -1 Ammonia is a colorless gas with a pungent odor. Non - Methane Organic 0.01 -0.6 NMOCs are organic compounds (i.e., compounds Compounds (NMOCs) that contain carbon). (Methane is an organic compound but is not considered an NMOC.) NMOCs may occur naturally or be formed by synthetic chemical processes. NMOCs most commonly found in landfills include acrylonitrile, benzene, 1,1- dichloroethane, 1,2 -cis dichloroethylene, dichloromethane, carbonyl sulfide, ethyl- benzene, hexane, methyl ethyl ketone, tetrachloroethylene, toluene, trichloroethylene, vinyl chloride, and xylenes. Hydrogen Sulfide 0 -1 Hydrogen sulfide and other sulfur compounds (e.g., dimethyl sulfide, mercaptans) are commonly found in landfills that give the landfill gas mixture its rotten -egg smell. Sulfides can cause unpleasant odors even at very low concentrations. 7 Newport Terrace Landfill — O &M Manual Table 1.

Source: Tchobangolous, Theisen, and Vigil 1993; EPA 1995. 1.5.1 Landfill Gas Levels at Newport Terrace At Newport Terrace, with the installation of the new vertical wells and collection piping, the concentration of methane in the collected gas is averaging about 4 to 5 percent. (Before the 2007 -08 modification of the system, the gas collected usually contained methane concentrations under 1.0 percent by volume, because (a) the collection piping had deteriorated over the years, allowing air intrusion; and (b) the original trench collectors were very shallow, and the system was located at the margins of refuse burial, possibly in native soil.) At Newport Terrace, based on monitoring performed since start-up of the new system, total NMOCs have been detected in the area of 40 ppmv (after carbon adsorption the concentrations have been reduced to under 10 ppmv). TACs in the collected gas have been consistently been detected at the levels (parts per billion, ppbv) shown in Table 2. Table 2. Non - Mefhane Organic Compounds Defected at Newport Terrace Compound Average Level Detected (ppbv) Benzene 10.0 Chlorobenzene E 2.0 Dichlorobenzenes 15.0 Dichloromethane 1.5 Perchloroethylene 3.0 Toluene 50.0 Tricholorothene 3.0 Chloroform 10.0 Vinyl Chloride 5.0 m +p xylenes 90.0 o- xylene 30.0 M Newport Terrace Landfill — O &M Manual After treatment, all levels decline to single -digit ppbv or non - detectable, with the exception of Vinyl Chloride, which remains at the 5.0 ppbv level, but well below the AQMD permit standard of 170 ppbv (0.17 ppmv). Hydrogen sulfide has not been detected in significant amounts. Title 27 of the California Code of Regulations (27 CCR), Section 20917, requires all municipal solid waste landfill operators to ensure that the concentration of methane gas generated from their landfill does not exceed 1.25 percent (by volume in air) in all on -site enclosed structures, excluding LFG control structures, nor 5 percent (by volume in air) in soils at the property boundary. Further, air quality regulations have been adopted which limit the amount of LFG that can be released into the atmosphere. SCAQMD Rule 1150.1 supports Title 27 by requiring subsurface monitoring, but also addresses surface emissions monitoring (although Newport Terrace is largely exempt due to its age.) Newport Terrace Landfill — O &M Manual 2 DESCRIPTION OF LFG CONTROL SYSTEM 2.1 SYSTEM OBJECTIVES AND GENERAL DESCRIPTION The primary objective of the Newport Terrace LFG system is to maintain methane concentrations of no more than 5 percent at the property boundary. The secondary objective of the system is to reduce emissions of non - methane organic compounds (NMOCs) of the collected LFG to less than 20 parts per million by volume (ppmv) (measured as hexane at 3 percent oxygen) or 98 percent destruction, thereby protecting air quality. The reduction of NMOC emissions is accomplished via the newly installed carbon adsorption units. These objectives meet the goals of regulations which govern the site, primarily those summarized below: California Code of Regulations (CCR) Title 27, Section 20917 et seq. This code requires the site owner to monitor for the presence or movement of subsurface LFG toward off -site locations. The monitoring is typically accomplished through installation of probes at the property boundary. This code also requires the owner to maintain a methane concentration of 5 percent or less at the property boundary and a methane concentration of 25 percent or less within on -site structures. The Local Enforcement Agency (LEA) administers the above regulation for the state. The LEA for the Newport Terrace site is the: Orange County Health Care Agency Environmental Health Division 1241 East Dyer Road, Suite 120 Santa Ana, CA 92705 (714) 433 -6000 • South Coast Air Quality Management District (AQMD) Rule 1150.1 Compliance Plan. The Newport Terrace site applied for a Rule 1150.1 Compliance Plan (Application #355993) which was approved on December 17, 1999. This plan describes compliance procedures for control of gaseous emissions from municipal solid waste landfills. The plan may be referenced in Appendix G. South Coast Air Quality Management District 21865 Copley Drive Diamond Bar, CA 91765 (909) 396 -2000 10 Newport Terrace Landfill — O &M Manual The Newport Terrace LFG Control System consists of three major components: • Monitoring Probes. Thirty -nine multi -depth monitoring wells, three containing three nested probes and the rest containing two probes, have been installed around the site boundary. (Note: These probes were all in place prior to the 2007 -08 system upgrade.) • Extraction Wells. Fifteen vertical extraction wells have been installed at the landfill. These extraction wells were constructed in 2008. The previously installed horizontal collectors are connected to the new system, and can be utilized in conjunction with the new wells, although their condition is not known. • Blower Station. A blower station is located in the Northwest corner and contains blower equipment, activated carbon adsorption units, a Sulfatreat system, and condensate separation equipment, all installed as part of the 2007 -08 construction. Record drawings for the system installed in 2008 are attached in Appendix A. 2.2 MONITORING PROBES Monitoring probes are located outside of refuse around the site perimeter. (These probes were part of the original LFG system and pre -date the 2008 construction). All the probes are multi - depth and contain casings which are capable of providing readings for different subsurface zones. Five of the probes contain three casings. The data that is known about the probes, including depth where available, is listed in Table 3. Probe locations are shown on Figure 2. Table 3.

EW 6 through 11 are in soils outside the perimeter of refuse placement. EW 12, 13, 14 and 15 were completed in the rubble fill area. The wells depths are shown in Table 4, and each contains a casing perforated in the lower 1/3 zone, approximately (see boring logs, Appendix B). Table 4.

The well casing is installed straight and plumb in the center of the 18 -inch diameter borehole (except wells EW -12 through EW -15, which have 12 -inch boreholes). The annular space surrounding the slotted well casing is filled with specified filter pack consisting of clean gravel backfrll 1 foot above the top of the slotted casing. The gravel backfrll is then covered with a 1 -foot layer of clean soil, followed by a 3 -foot bentonite plug. The casing is backfilled with soil up to 4 feet 6 inches below ground surface, and an additional 2- foot bentonite plug is then placed. The well is completed by installing a valve box with concrete surround and a gravel base. A control valve and monitoring tubing with labcock valves are also installed with a valve box. 15 Newport Terrace Landfill — O&M Manual 2.4 BLOWER STATION The blower station is located within a building with locking doors. Four blowers, a moisture separating tank, two activated carbon adsorber units, a sulfatreat system, and electrical controls are located within the blower station. Highlights of the major blower station components are given below. 2.4.1 Moisture Separating Tank The first equipment LFG reaches in the station is the moisture separator (knockout) vessel. The LFG is introduced into the knockout near the midpoint and exhausted at the top. While rising through the tank, condensate and particulates are removed from the gas stream through a filter (demister). This condensate drains from the knockout bottom to a pipe and flows by gravity to the condensate sump (CS -1). 2.4.2 Blowers Four blowers are installed in the station. There are two CP404M H2S blowers and two CP808 LFG blowers. Information on the blowers is provided below. Manufacturer: Rotron; Saugerties, NY 12477 Motor Model Numbers: H2S blowers: CP- 404FQ58MLR - 1.0 hp 115/230 V, 60 Hz, 1 Phase 107 cfm capacity each LFG Blowers: CP- 808FX5MWLR - 5.5 hp 230 V, 60 Hz, 1 Phase 300 cfm capacity each Type: Sealed Regenerative w /Explosion -Proof Motor 2.4.3 Activated Carbon Adsorption Units Two skid mounted activated carbon adsorption units (vessels), installed in series, are located within the blower station, each containing 2,000 Ibs of material. The carbon is R 4X8 series granular activated carbon (GAC) from Baker Filtration. The purpose of the activated carbon is to remove the non - methane organic compounds (NMOCs) of the LFG by adsorption. A sampling port is provided at the exhaust side of each unit to monitor the carbon performance. Upon detection of unacceptable levels of NMOCs at the first vessel exhaust which is specified in the AQMD permit as 20 ppm as hexane (see Appendix D), the material is considered exhausted and the unit contents must be removed and reloaded with fresh (regenerated) GAC. The LFG passes through each adsorption unit in series, and the units are intended to operate as a primary unit and secondary unit. When carbon in the primary becomes "saturated," i.e., can no longer adsorb NMOCs, "breakthrough" will be detected and the secondary unit becomes the principal adsorber. 11112 Newport Terrace Landfill — O &M Manual At that point, fresh carbon should be ordered for the primary unit; and after it has been replaced, the flow should be reversed (using the available valves), so that the secondary unit becomes the primary. (For example, if the system is running with gas flowing from Vessel A to Vessel B, when the gas exiting Vessel A exceeds 20 ppm NMOCs, replacement carbon should be ordered and put into Vessel A, then the system should be reversed such that the gas flows from Vessel B to Vessel A.) The LFG control system must be shut down during unloading and reloading of carbon. 2.4.4 Sulfatreat System One skid mounted sulfur absorber is located within the blower station, containing 2,000 lbs of material ( "Sulfatreat'). The purpose of the Sulfatreat system is to remove the sulfur compounds of the LFG collected in header line `B ". A sampling port is provided at the exhaust and intake sides to monitor the Sulfatreat performance. The discharge of the Sulfatreat system is into the carbon adsorption units. Upon detection of unacceptable levels of sulfur measured as HZS at the Sulfatreat exhaust ( "breakthrough ") which is specified in the AQMD permit — a maximum of 0.1 ppmv sulfur at the exhaust of the carbon system (see Appendix D) — the material is considered exhausted and the unit contents must be removed and reloaded with fresh Sulfatreat material. The LFG control system serving Line B is shut down during unloading and reloading of Sulfatreat material in the unit. 2.5 SITE SECURITY The blower facility is contained within a lockable building — keys are maintained by the city staff and its contractors. The building doors are connected to an alarm system — entry sends a signal to the city Utilities Department. Authorized personnel are issued two keys — one to enter the building and a second to suppress the alarm. The operations contractor is be responsible for ensuring appropriate signage is placed on the exterior of the blower facility (e.g. "Keep Out'). Well control valves, monitoring probes, condensate sumps are contained in valve /utility boxes as illustrated on the as- builts (see Appendix A), and require a lifting tool and wrench to access. 17 Newport Terrace Landfill — O &M Manual 3 LFG CONDENSATE HANDLING SYSTEM 3.1 LFG CONDENSATE LFG condensate is a liquid which develops as LFG cools while flowing in the collection system. It is mostly water but contains some dissolved organics and often is acidic (due to carbon dioxide in the LFG). LFG condensate must be removed - from the collection piping system or it could collect in low points and cause gas flow blockage. Condensate shall be disposed of as hazardous waste unless otherwise determined by laboratory tests. 3.2 GAS CONDENSATE HANDLING SYSTEM DESCRIPTION Condensate collection facilities are shown on Sheets 3 (location) and 5 (details) of the system drawings (Appendix A). To collect and remove LFG condensate, four sumps (CS -1 through -4) are incorporated into the collection header (Line A), and a moisture knockout is located in the blower station. The sumps are pneumatic in operation — air is supplied from a compressor in the blower station and via HDPE pipes in the collection header trenches. When the liquid level in the sump reaches a certain point, a float - control valve activates the air supply to the pneumatic pump, and liquid is pumped back into the header to continue flowing downhill to the next sump /low point, where the process is repeated. At the downhill end of the header system (past EW 11), the liquid is pumped out of the last trap to a discharge line which runs north into an existing city sewer manhole in the condominium development in Seabird Court. For Line B, condensate is allowed to drain back into EW 14. In the blower station, all gas travels through the condensate knockouts (one each for Line A and B). The condensate flows by gravity to CS -1 where it is pumped into the header to ultimately flow to the city sewer. 3.3 HANDLING LFG CONDENSATE LFG condensate may contain many trace chemicals and be highly biologically active. Appropriate protective gloves and splash protection equipment should always be employed when working with LFG condensate. Operating personnel should always avoid direct skin contact. 18 e Newport Terrace Landfill — O &M Manual 4 SYSTEM OPERATION 4.1 OPERATIONAL CRITERIA The Newport Terrace LFG Control System operational criteria are based on the system design, regulatory requirements, and past experience with other LFG extraction systems. The criteria summarized below follow the AQMD Permit to Construct/Operate (PTO) (see Appendices C _ and D): • Methane concentration shall be maintained at less than 5 percent by volume at all perimeter probes. • The concentration of total NMOCs at the final outlet of the carbon adsorption units shall not exceed 20 ppmv or achieve 98 percent destruction removal efficiency. The sulfur concentration, measured as HZS at the final outlet of the carbon adsorption unit shall be below 0.1 ppmv. A more extensive discussion of permitting requirements is presented in Section 1.2. 4.2 SYSTEM START -UP The system requires start up upon power shutdown, carbon adsorption unit replacement, blower maintenance, or other operation interruption. Only qualified, experienced staff is recommended as operators to start the system using the following guidelines: 1. Check for alarms before entering blower house. 2. Check the system instrumentation for malfunctions (Yokogawa recorder, Kurz flowmeter, Race autodialer, General Monitors gas detectors), which are indicated by trouble- lights on the control panel. 3. Check air compressor pressure (normal operating pressure is 100 psig). 4. Confirm main gas inlet valve HV -1 is open. 5. Confirm inlet and outlet valves (HV -2 and 3 or HV -4 and 5) are open for the selected blower. 6. Confirm valves for the Carbon vessels are set correctly (for V -1 primary and V -2 secondary, valve position is as follows: HV -6, 9, 10, and 13 open; valves HV -7, 8, 11, and 12 closed). 7. Confirm hydrogen sulfide gas inlet valve HV -14 is open. 19 Newport Terrace Landfill — O &M Manual 8. Confirm inlet and outlet valves (HV -15 and 16 or HV -17 and 18) are open for the selected Sulfatreat blower. 9. Confirm Sulfatreat outlet valve HV -19 is open. 10. Select Blower No. 1 or Blower No. 2 for the methane system and select Blower No. 3 or Blower No. 4 for the hydrogen sulfide system. (Note: Use hours meters on blowers to balance long -term usage.) 11. Turn the blower control selector switches to "AUTO." 12. Confirm that selected blowers are operating. 13. Confirm that operating parameters are within acceptable limits. For the initially installed equipment, the following should apply: - Main system— vacuum maximum 60 inches; flow between 200 scfm and 300 scfin (maximum under SCAQMD Permit). - H2S system —vacuum maximum 45 inches; flow between 40 to 80 scfm. - Inlet gas temperature maximum below 140 °F. Use the following procedure to shutdown the treatment system: 14. Turn blowers I through 4 to the "OFF" position. 15. Close inlet valves HV -1 and HV -14. 4.3 SYSTEM SHUTDOWN It will be necessary to periodically shut the system down for repair or service. Use the following procedure to shutdown the treatment system: 1. Turn blowers 1 through 4 to the "OFF" position (on control panels). 2. Close inlet valves HV -1 and HV -14. 3. Additional steps may be required for extensive maintenance or repair activities. 4.4 OPERATION SCHEDULE The blower station is equipped with a timer for an automatic start up and shutdown to allow the system to operate a minimal amount of hours while still preventing methane concentrations above 5 percent at the perimeter. i Newport Terrace Landfill — O &M Manual The operating schedule (as of October 2008) is 10 hours per day, 7 days per week. It may be possible over time to reduce these hours to minimize operating costs and system wear, while meeting regulatory performance goals. Iteratively, the system flow should be reduced while watching probe methane concentrations — until monitoring data suggest that further reductions in operating times could result in methane exceeding the 5 percent limit. Changes to the operating schedule should be discussed with and approved by city staff. 4.5 REMOTE MONITORING BY CITY Remote monitoring of the on -site alarm systems within the equipment building will be handled by the Utilities Department. Such monitoring will be accomplished by wireless means with a telephone land -line connection as backup. Information relative to power outage, blower failure, gas detection, and unauthorized building entry is transmitted to the city's SCADA system on a real -time basis which is continuously monitored. Operation and maintenance of remote monitoring equipment are the responsibility of the Utilities Department. Operation and maintenance of the on -site alarm system within the equipment building are the responsibility of the O &M contractor. The O &M contractor shall provide contact information to the Utilities Department so that alarms detected by the remote monitoring can be relayed to the O &M contractor for response on a "24/7" basis. The contact information must be kept current during the O &M contract term. 07F Newport Terrace Landfill — O &M Manual 5 SYSTEM MONITORING 5.1 MONITORING CRITERIA Routine monitoring is scheduled at the Newport Terrace LFG Control System to check its conformance with the regulatory criteria and permits described in Section 3 of this report, as follows: • Methane concentration shall be maintained at less than 5 percent by volume at all perimeter probes. • The concentration of total NMOCs at the final outlet of the carbon units shall not exceed 20 ppmv or achieve 98 percent destruction removal efficiency. Sulfur concentration measured as HzS at the final outlet of the carbon adsorption system shall not exceed 0.1 ppm. In addition, monitoring is performed to keep the system running at its optimum efficiency. Experienced, qualified LFG technical staff is recommended to perform the monitoring tasks. 5.2 MONITORING EQUIPMENT Monitoring techniques described in this manual involve commonly used battery- operated instruments which have proven to be easy to use and provide reliable results. The following monitoring equipment is needed to perform recommended monitoring. Alternative equipment may be utilized if it can provide suitable, dependable data. 5.2.1 Combustible Gas Monitoring Instrument For monitoring methane at the extraction wells, monitoring probes, and the blower station, a portable combustible gas analyzer is necessary. At a minimum, the gas analyzer must be capable of measuring methane in percent by volume and percent LEL. Instruments are available which measure methane as well as oxygen, carbon dioxide, pressure, vacuum, and temperature, but these are more expensive. Measurement of carbon monoxide and temperature may be considered optional and warranted under special conditions, such as suspicion of subsurface combustion. Gas instruments are to be calibrated in accordance with the manufacturer's procedures and schedules. There are numerous portable gas instruments available. However, the preferred instrument is the Landtec GEM -2000. This instrument is recommended and detects methane, oxygen, carbon dioxide, and nitrogen, as well as static pressure and flow rate. 5.2.2 Photo Ionization Detector (PID) A PID is recommended (referred to as an organic vapor analyzer in the SCAQMD Permit to Operate) to measure the emission at the carbon adsorption unit exhaust. A PID measures all organic components in the gas stream, except methane. 22 Newport Terrace Landfill — O &M Manual Either of the following instruments may be considered appropriate for this site: Thermo Electron TVA 100013 Vapor Analyzer www.thermo.com MiniRAE 2000 RAESales@raesystems.com 5.2.3 -- Hydrogen Sulfide Measurement Drager tubes or H2S detectors are used to measure the sulfur emissions as H2S. A bag sample needs to be taken from the outlet of the Sulfatreat system for testing for H2S. A Drager tube or other instrument is used to determine if the sulfur emissions are above 0.2 ppmv. A bag sample can be taken using a sampling box. SCS recommends taking bag samples to measure the sulfur emissions at the rubble fill wells (EW -12, EW -13, EW -14, and EW -15). 5.2.4 Pressure /Vacuum Gauges Portable pressure /vacuum gauges are required for field measurements at the extraction wells and monitoring probes. Appropriate, permanent gauges are installed on -line at the blower station piping. (Note: The GEM 2000 allows direct reading of static and differential pressures and so can service this purpose.) The ranges of pressure /vacuum typically encountered at sites such as Newport Terrace would be from 0 to 30 inches -water column. Magnehelics or a digital manometer may also be used for pressure measurements. 5.2.5 Miscellaneous Tedlar bags will be required for LFG samples taken at the carbon adsorption unit inlets and emission sample at the outlet of the final carbon adsorption unit. Tedlar bag and Drager Tube that can measure down to 0.2 ppmv H2S or equivalent equipment is necessary to measure the inlet and exhaust of the Sulfatreat system. Gas samples from the inlet are analyzed for VOCs and speciated for Toxic Air Contaminants (TACs, as defined in SCAQMD Rule 1150.1) and the gas samples from the exhaust of the carbon system are analyzed for chloroform, vinyl chloride, and hydrogen sulfide in the laboratory in accordance with the AQMD permit. 5.3 MONITORING PROCEDURES Monitoring procedures include visual inspection, meter reading, and testing with field instruments. Monitoring results should be recorded directly into the instrument (if capable) or onto an inspection form (Appendix E). 23 Newport Terrace Landfill - O &M Manual The system is monitored for the following items: 24 Subject Method Methane Inlet System Inlet separator Differential pressure, in H2O Gauge reading Inlet gas temperature Temperature, °F Gauge reading Inlet gas pressure Pressure, in H2O Gauge reading Blower discharge temperature Temperature, °F Gauge reading H2S Inlet System Inlet Separator Differential pressure, in H2O Gauge reading Sulfatreat discharge temperature Temperature, °F Gauge reading Sulfatreat discharge pressure Pressure, in H2O Gauge reading Blower discharge pressure Pressure, in H2O Gauge reading Instrumentation - Operating System Gas flowrate Flowrate, SUM Kurz meter Total gas flow Volume, SCF Kurz meter Major gases (CH4, CO2, N2, 02) Percent by volume GEM 2000 (inst. test) 1-12S concentration ppm Drager Tube (inst. test) Air compressor pressure Pressure, psi Gauge reading Air compressor hours Elapsed time, hr Gauge reading Blowers (H -O -A) Lead blowers Note switch position Blower hours (each) Elapsed time, hr Gauge reading Blower Station Automated Safety Monitoring Percent combustibles - percent LEL - General Monitors Sensor /Alarm H2S concentration- ppm H2S - General Monitors Sensor /Alarm Carbon Adsorbers Vessel No. 1 inlet NMOC Concentration PID Instrument test Vessel No. 1 outlet NMOC Concentration PID Instrument test Vessel No. 2 outlet NMOC Concentration PID Instrument test Sulfatreat System outlet Sulfur Concentration (as H2S) Drager Tube or other inst. 24 Newport Terrace Landfill — O &M Manual Extraction Wells (each) Pressure /Vacuum Instrument test Temperature Instrument test Methane Instrument test Oxygen Instrument test Carbon Dioxide Instrument test Monitoring Probes (each) Pressure /Vacuum Instrument test Methane Instrument test Oxygen Instrument test Carbon Dioxide Instrument test All instrument readings are taken at cock valve hose fittings under the procedures noted below. 5.3.1 Carbon Adsorption Units (Each) 1.

Record instrument reading for methane, carbon dioxide, oxygen and balance gas, if included, upon stabilization. PM Newport Terrace Landfill — O &M Manual 6. Close cock valve. 7. Remove hose and instrument. S. Repeat Steps 4 through 8 for all subsurface zone cock valves. 5.3.4.3 Methane Concentration Exceedance When gas monitoring indicate concentrations of methane in excess of the compliance level, do some combination of the following to bring the probe back into compliance with the requirements of CCR Title 27: 1. If a probe has more than 5% methane, notify the Landfill owner and LEA within 1 business day of the monitoring event. 2. Within 7 days of the detection of exceedance verify the result by performing the following: • Monitor probe weekly. • Verify that the blower is running properly and that there are no water restrictions or air leaks in the pipe. • Increase and optimize landfill gas collection using the existing gas collection wells. This may require increasing the blower speed using the variable frequency drive. • Improve gas collection by improving Landfill surface cover to decrease air infiltration. • Evaluate the effects of barometric pressure. • Verify the probe(s) measurements. • Inform LEA of actions taken to control LFG by e-mail or letter. 3. If the initial verification indicates exceedance, continue monitoring on a weekly to allow the methane concentration drop to below 5% in response to the system adjustments/ optimization. 4. Within 21 days of first methane exceedance, submit to the LEA a letter workplan which describes the nature and extent of the problem, all operational actions taken, and recommended corrective actions needed to protect public health and safety and the environment. The letter should: • Evaluate the problem. • State actions taken to date. • Evaluate appropriate alternatives. Alternatives may include some combination of the following: — Install additional interior landfill gas extraction well(s) — Replace the blower with a larger unit. 27 Newport Terrace Landfill — O &M Manual — Other control alternatives -the purpose of this category is to acknowledge that new technologies are continually being developed and that a new technology may be the preferred approach. • Bar hole punch (3 foot depth) and monitor by all homes within 25 feet of probe weekly. • An implementation schedule of the selected alternative and anticipated schedule to bring the probe into compliance. 5. After probe readings decrease to below compliance levels, continue weekly monitoring for four (4) consecutive weeks. After four (4) consecutive weeks of readings below compliance levels, the monitoring frequency may revert to monthly or as otherwise approved by the LEA. 6. If exceedances return, increase monitoring frequency to weekly and reinitiate evaluation, and implementation of control measures. 5.4 MONITORING RECORDS AND SCHEDULE The probes are monitored monthly for TOCs (reported as methane) and lab analyzed quarterly for TACs. A Tedlar bag sample needs to be lab analyzed for TOCs quarterly. All other monitoring events happen monthly except the source test which is performed annually (see Table 5b). Table 5a. Monitoring Schedule 28 Monthly Quarterly Annually Collect and lab analyze sample from inlet and outlet of carbon x system for VOCs and TACs Monitor Sulfatreat exhaust for H2S with Drager Tubes x Monitor TNMOC concentration at each carbon adsorber outlet x with PID Monitor boundary probes for TOCs (as methane) using x portable instrument Collect sample(s) from boundary probe(s) for lab x analysis of TACs and TOC Source Test x 28 Newport Terrace Landfill — O &M Manual Field measurements should be recorded directly either directly into monitoring instruments that have data logging capability (e.g., GEM), or onto paper monitoring forms (see example forms, Appendix E). If monitoring data is recorded on the instrument, that data should be uploaded to a data management system which can be queried for trends and reporting. Original records shall be saved for a minimum of 2 years in accordance with the SCAQMD Permits and 3 years per LEA requirements. In practice however, all data should be securely stored electronically for future use, which may be assumed to be for 20 years or more. In addition to the reporting required by regulatory agencies (LEA and SCAQMD), monitoring and maintenance data should always be sent to the City of Newport Beach and the Newport Condominium Association. 5.5 REPORTING TO REGULATORY AGENCIES Monitoring results are required to be reported to two regulatory agencies, the solid waste local enforcement agency (LEA) within five days of monitoring event, and the South Coast Air Quality Management District.

The maintenance program consists of the observation and servicing of mechanical equipment and other components. Most of the equipment at the blower station is to be maintained according to manufacturer's criteria. This equipment includes the blowers, electrical controls, activated carbon canisters, Sulfatreat system, and moisture separating tank. The remainder of the system components is to be maintained by field staff. These components include the header /lateral/blower station piping, cock valves, check valves, in -line meters, and valve boxes. The safety and orderliness of the blower building, as well as the accessible wellfteld facilities (well and probe vaults) are the responsibility of the system operator. This includes preventing and repairing damage from vermin. 6.2 MAINTENANCE PROCEDURES Visual inspection is the typical maintenance procedure, as described below, to be performed outside of the manufacturer's requirements. In general, the operator should do a visual inspection each time they enter the blower building and/or open well -field or probe vaults. Signs of unusual deterioration, damage (including from animals) shall be noted on a monthly log, included in Appendix E, and addressed as necessary. Equipment literature, including maintenance details, are included in Appendix H. 6.2.1 Compressor An Atlas Copco GX -4 air compressor provides pressurized air for the pneumatic pumps in the condensate sumps. Maintenance principally involves checking and maintaining the oil level, and cleaning air and oil filters. However, it is important that the operator respond to signs of incipient failure (unusual wear, or sounds or smells) in order to anticipate or react quickly to equipment failure, to allow planning for equipment replacement and minimize system downtime. 6.2.2 Blowers The manufacturer requires periodic inspection and service typically based on hours of service as measured by the elapsed time meter. BE Newport Terrace Landfill — O &M Manual 6.2.3 Flame Arrestor The flame arrestor will require disassembly and cleaning if the differential pressure exceeds two inches water - column. 6.2.4 Moisture Separator The moisture separator should be visually inspected for corrosion, weathering, leaks, seals, and pressure drop. An increase in pressure drop, measured at the sampling ports, one on each of the tank inlet and outlet pipes, indicates the unit is clogged and should be cleaned. Accumulated moisture in the separator, indicated also by an increase in pressure drop across the unit, should be drained by opening the drainage valve at the base of the unit. 6.2.5 Electrical Controls The system should be start-up tested monthly. The electrical controls should be visually inspected monthly or more frequently. 6.2.6 Gauges and Sampling Ports Permanent station gauges and sampling ports should be visually inspected for damage, proper seating and fit, and accuracy. Gauges need to be zeroed prior to recording readings. 6.2.7 Piping, Valves, and Fittings Piping, valves, and fittings within the station should be visually inspected for damage, corrosion, weathering, seal, and leaks. 6.2.8 Extraction Wells Visually inspect the wells at least once a month as follows: 1. Check inside the vaults and look for damage and proper operation of the well head, later tie in (flex hose) and condensate drain. 2. Check the sampling ports and gate valve for damage, leaks, workability, and seating. 3. Check the lateral piping for damage and leaks. 4. Check the modified condensate drains for damage or leaks. 6.2.9 Monitoring Probes Visually inspect the probes as follows: 1. Check the valve box, valve box cover, and identification tags for damage. 2. Check the cock valves for damage, leaks, workability, and seating. 33 Newport Terrace Landfill — O &M Manual 6.2.10 Carbon Adsorption Units Upon detection of "breakthrough" (exceedance of NMOCs at the carbon units' final exhaust, as measured by PID), the carbon shall be replaced and /or reactivated by an approved carbon provider as necessary. The sequence of carbon change -out is discussed in Section 2.4.3. 6.2.11 Sulfatreat System When breakthrough of H2S is detected (Drager Tube reading of 0.1 ppmv), the Sulfatreat media needs to be replaced, by contacting the Sulfa -treat vendor. 6.2.12 In -Line Flow Meter The Kurz flow transmitter uses thermal conductivity to measure the rate of flow of gas passing through the pipe. The heated sensor should be removed and cleaned annually. 6.2.13 Automated Condensate Sumps The four automated sumps should be visually inspected during routine monthly monitoring. 6.3 MAINTENANCE RECORDS AND SCHEDULE Routine maintenance activities at the blower station should be performed weekly, monthly, quarterly or annually, as described above and summarized in Table 6a I. Monitoring forms for these maintenance activities are included in Appendix E All maintenance work should be promptly and neatly recorded and retained as a permanent record to track long -term changes or trends in the equipment performance. This record is used for planning future preventive maintenance or in diagnosing equipment breakdowns. Section 7 discusses data management. An annual maintenance and monitoring report shall be submitted by the owner to the solid waste local enforcement agency (LEA) by March I" of every year. Report shall include all maintenance performed on the system. 1 Monitoring Forms are included in Appendix E. 34 Newport Terrace Landfill — O&M Manual TABLE 6a.

This process of collecting, evaluating, and managing data may be relatively simple or very complex. The level of complexity depends on the problems that a site presents, the evaluation or control objectives, resources available, and budget constraints. The process may be as simple as measuring and recording several key parameters on a reading sheet and making immediate on the spot adjustments in the field, or as detailed as performing systematic analysis using sophisticated software employing graphing or plotting data in multiple dimensions. 7.2 DATA COLLECTION The data required by the SCAQMD Permits to Operate are as follows: • The quantity of LFG in standard cubic feet per minute being treated by the carbon adsorbers. • The concentration of TNMOCs at the combined inlet to the carbon adsorption system. • The concentration of TNMOCs at the final outlet of the carbon adsorber. • Annual source tests of the carbon adsorber system inlet and final outlet. • VOC and TAC samples collected from the inlet and outlet of the carbon adsorbers. • Sulfur compounds (measured as HZS) concentration at the exhaust of the Sulfatreat system. • Emissions at the exhaust of the carbon adsorbers sent to a lab to determine concentration of chloroform, vinyl chloride, and hydrogen sulfide. • Test results. • Monitoring data. • Dates of carbon replacement. Data is collected routinely using monitoring forms (either manual or electronic) for the blower facility, the wellfield, migration monitoring probes, onsite structures, etc. These data readings become a part of the facility operating record. A retention period of at least three years is required by the solid waste local enforcement agency (LEA). 36 Newport Terrace Landfill — O &M Manual The system operator (contractor) will retain all monitoring and maintenance records, as well as providing digital copies to the City of Newport Beach and the NCA. Contact information for the city and NCA are listed in Appendix F. The city and NCA will each be responsible for archiving monitoring and maintenance records. A contractor working for the city or NCA should retain data for 10 years. The city and NCA should retain data for at least as long as the landfill and LFG system are subject to regulatory oversight (i.e., indefinitely). 37 Newport Terrace Landfill — O &M Manual 8 SAFETY The principle components of LFG are methane and carbon dioxide; other gases which may be found in lesser amounts are hydrogen sulfide, organic acids and gases, and nitrogen. Hydrogen sulfide is HIGHLY TOXIC; the other acidic gases and organic vapors should also be treated as toxic and hazardous. In concentrations of 5 to 15 percent by volume in air, methane may explode when ignited by a spark or other ignition source. In addition, LFG can displace oxygen in confined spaces. Confined spaces within which oxygen levels are below 19 percent by volume should not be entered. This manual does not contain a Health and Safety Plan (HASP), nor does it contain lock -out, tag - out procedures. The LFG system operator needs to develop a site - specific HASP (including lock -out, tag -out procedures) based on analysis of the existing site conditions. 8.1 CONTACT INFORMATION Appendix F lists major stakeholder and regulatory parties contact information. 38 Newport Terrace Landfill — O&M Manual 9 LISTING OF PERMITS South Coast Air Quality Management District, Permit to Construct/Operate, No. F85011, issued November 6, 2006 (Appendix C) — no specific expiration date..
