SECTION A SUMMARY OF LANDFILL GAS FLARING IN 2003 AND 2004 Summary of W12A Landfill Gas Flaring 2003 On June 23, 2003, a temporary landfill gas (LFG) flaring system became operational at the City of London s W12A landfill. However, the data logger was not operational until September 19, 2003. Therefore, the LFG quantities flared between June 23 and September 19 are not included in the determination of emission reduction credits (ERCs). The temporary LFG flare system remained operational until December 19, 2003. During that time, 269.5 tonnes of methane were destroyed in the flare. Based on methane s global warming potential (GWP = 21), this is equivalent to 5,660 tonnes of greenhouse gases avoided (GHGs expressed in terms of equivalent carbon dioxide). Summary of W12A Landfill Gas Flaring 2004 On June 20, 2004, the permanent LFG flaring system became operational at the W12A landfill. Initially, the system was collecting around 0.35 standard cubic metres per second (or 750 Scfm) of LFG with a methane content of 45%. This is equivalent to approximately 4,100 tonnes of methane destroyed (85,000 tonnes of greenhouse gases) per year had this LFG flowrate been maintained with minimal down time. However, by early December, LFG gas flow to the LFG flare had dropped to around 0.24 m 3 /s (500 Scfm) with a methane content of 50%. This is equivalent to approximately 2,200 tonnes of methane destroyed (46,000 tonnes of greenhouse gases) per year. Some of this drop can be attributed to depletion of pent-up landfill gas. However, most of this drop can be attributed to the commissioning and operational problems outlined below. During 2004, 852 tonnes of methane were destroyed in the flare. This is equivalent to 17,897 tonnes of greenhouse gases avoided. The quantity of GHG emission reductions created by the landfill flare in 2004 was approximately 25% of the amount of gas stated in the Purchase and Sale of Greenhouse Gas Emission Reduction Agreement between the City of London and Environment Canada. The reduced quantity is the result of three factors: 1. Delays in Flare Delivery - Delays in the fabrication of the flare by LFG Specialties in Ohio delayed start up of the system until the end of June. As a result the system was only operational for approximately 6 months in 2004. In future years, GHG emission reductions should double with year round operation. 2. Commissioning/Operational Problems - Since beginning operation, the flare has been shut down approximately 20% of the time due to commissioning/operational problems. Commissioning problems have included valves sticking in cold weather (valves have since been insulated) and fluctuating pressures in collection line. The latter problem periodically caused the system to shut down because of high suction pressures at the flare. It was only after several shutdowns that the cause of the problem was determined (pressure testing plug left in collection line). The pressure PERRL Emission Reduction Claim Report 2003 and 2004
testing plug was removed in late December 2004. Subsequently, methane content at the flare increased from 50% to 70%. An ongoing operational problem that is continuing to cause the flare to periodically shut down is the poor electrical supply to the landfill. Short term power fluctuations (i.e., equivalent to lights flickering) can cause the flare to shut down. The City plans on installing an uninterrupted power supply (UPS) at the flare in 2005. 3. Base Flow to the Flare was Less Than Originally Estimated - There is less gas being collected when the system is running than originally projected. The main reason for the reduced flow is because no gas is being collected from an area that was expected to produce significant gas quantities given the type and age of the waste buried. A test well drilled in this area produced high gas flows (0.03 m 3 /s or 60 cfm) however the nine production wells drilled in this area are flooded. Calculation Method for Methane Destruction The W12A Landfill s LFG flaring system is equipped with on-line continuous monitors for the following: Oxygen concentration (percent by volume) Methane concentration (percent by volume) Flare temperature ( C) LFG flow to the flare (cubic feet per minute, corrected to standard conditions) The LFG flaring system s datalogger records these data every two minutes. The quantities of methane destroyed in the flare were calculated in two-minute intervals based on the following formula: M CH4 = 0.4536 DRE V LFG c CH4 ρ CH4 Where, M CH4 = mass flowrate of methane to LFG flare (kilograms/minute) DRE = destruction removal efficiency (99%) V LFG = volume flowrate of LFG to flare (standard cubic feet per minute) c CH4 = methane concentration (percent by volume) ρ CH4 = methane density at standard conditions (0.0409 lbs/sft 3 ) Data from periods where the LFG flare system was not in operation (i.e., when the LFG gas flowrate fell below 300 Scfm) were excluded in these calculations. Example Calculation On July 2, 2004 at 3:30 pm, the following operating conditions were observed: Methane concentration - 52.5 % LFG flow to the flare 794 cfm (or Sft 3 /minute) PERRL Emission Reduction Claim Report 2003 and 2004
Based on the formula above: M CH4 = 0.4536 DRE V LFG c CH4 ρ CH4 = 0. 4536 kg/lbs 0.99 794 Sft 3 /minute 0.525 0.0409 lbs/ Sft 3 = 7.66 kg/minute W12A Landfill Gas Flaring System - Plans for 2005 As of December 31, 2004, the LFG flaring system was running at around 70% methane concentration with a LFG flowrate around 0.21 m 3 /s (450 Scfm). This is equivalent to approximately 3,100 tonnes of methane destroyed (65,000 tonnes of greenhouse gases) per year if this LFG flowrate is maintained with minimal down time. The City has approved a capital expenditure of $600,000 in 2005 in order to increase the base flow of landfill gas. Options for increasing the flow are: Decrease Well Spacing in Existing Well Field - The existing gas wells that are spaced relatively far apart and the zone of influence for the wells do not overlap. Consideration will be given to adding additional wells in the existing well fields. Lower Leachate Levels in Flooded Wells - Alternatives for lowering the leachate levels in the flooded wells will be examined. Drilling additional wells beside the gas production wells and pumping the leachate is likely to be the most cost effective method. A test well will likely be drilled in early 2005 to determine the effectiveness of this alternative. Expanding Into New Areas - Approximately 8 hectares of landfill reached capacity and was capped in 2004. Consideration will be given to expanding the well field into this area. It is anticipated that the work mentioned above could increase the LFG flowrate up to 0.57 m 3 /s (1200 Scfm) with a methane concentration of 50%. This could increase the annual methane destruction rate up to approximately 5,700 tonnes of methane (120,000 tonnes of greenhouse gases) y:\shared\solwaste\w12a\landfill gas\perrl submission\summary of w12a landfill gas flaring 2003-2004.doc PERRL Emission Reduction Claim Report 2003 and 2004

Greenhouse Gas ERCs from Landfill Gas Flaring Desktop Review The Corporation of the City of London SUMMARY This project review addresses the requirements for a third party verification audit of greenhouse gas emission reduction credits generated from a landfill gas collection and combustion system under the Pilot Emissions Removals, Reductions and Learnings (PERRL) Initiative. The current document covers the requirements for a Desktop Review Report under the PERRL Verification Protocol (Section 7.0) of the PERRL Proponent s Application Manual, Version 1.0. It is the opinion of the reviewer that the emission reduction credits presented by the proponent are real, measurable and verifiable. Project Scope The project scope accurately defines a valid greenhouse gas reduction activity, with substantiated supporting information. The technical details of the activity changed from the original proposal to the actual installed equipment, however the as built system provides a greater degree of data reliability for the supporting of emission reduction credit calculations than the original proposed system. Emission Reduction Calculations The calculation of the stated Emission Reduction Credits was conducted without error according to accepted standard methodologies. The data used for the performance of the calculations were all derived from reliable sources which were traceable to either a specified manufacturer s performance guarantee or a primary calibration standard. The calculations correctly accounted for periods of operational downtime where no landfill gas flaring was occurring. D.H.Lyons Page 1 Feb 2005 Project 05-01

Greenhouse Gas ERCs from Landfill Gas Flaring Desktop Review The Corporation of the City of London 2 REVIEW OF LFG CAPTURE AND CONTROL PROJECT 2.1 Project Summary 2.1.1 Project Scope The project covers the operation of a landfill gas collection and combustion system operated at the existing W12A landfill by the Corporation of the City of London. The system is described under the original proposal provided by the city to PERRL in December, 2002. The system consists of a series of landfill gas extraction wells installed over a closed area of the pre-existing landfill site. The extracted gas is mechanically pumped to a collection station and routed through a flare. A condensate removal system is used to prevent liquid carryover into the collection system and continuous online monitoring is provided for methane concentration, flow rate, oxygen concentration and flare temperature. The control system is designed to maintain the flare combustion at the optimal design conditions, and will vary the flow rate and excess combustion air requirements as needed to maintain a constant combustion profile. Following installation of the landfill gas collection system, a temporary flare was installed during late 2003 to provide some measure of greenhouse gas combustion during construction and commissioning of the permanent installed system for 2004. The operational and commissioning history of the system is adequately described in the proponent s summary report for 2003-2004. The project as described and installed by the proponent constitutes a recognized and acceptable means of reducing greenhouse gas emissions through the collection and conversion of excess methane generated by the landfill to carbon dioxide. Without the described collection and combustion system, methane generated from the landfill would escape uncontrolled to the atmosphere. 2.1.2 Emission Reduction Claim The proponent described the baseline scenario of uncontrolled methane emissions according to the accepted PERRL specification using the U.S. EPA LandGEM model. The identification of potential emission reductions were based on the measured methane concentrations and landfill gas flow rates following the collection of the collection and combustion systems. Owing to stated operational and commissioning problems during initial startup, the volumes of landfill gas collected for 2003 and 2004 were given as significantly lower than for the projected future operation of the system. These assumptions are reasonable given the operational data at hand and the proposed future modifications to the system, although any future emission reduction claims would be based on actual measured data for the following years.

Greenhouse Gas ERCs from Landfill Gas Flaring Desktop Review The Corporation of the City of London 2.2 Emission Reduction Calculations 2.2.1 Calculation Methodology The determination of the emission reduction credits for 2003 and 2004 was based on the calculated volume of methane collected and combusted over the operational period. The approach used by the proponent for this calculation is a straight mass balance based on measured operating data from the installed system: M CH4 = DRE V LFG c CH4 ρ CH4 Where, M CH4 = mass flowrate of methane to LFG flare DRE = destruction removal efficiency of flare (99%) V LFG c CH4 ρ CH4 = volume flowrate of LFG to flare at standard conditions = methane concentration (percent by volume) = methane density at standard conditions This is the preferred approach for determining the operational behaviour of the system as it is based to the greatest degree practical on directly measurable data. 2.2.2 Data Sources The calculation of greenhouse gas emission reduction credits depends on the reliability of three key sources of information: Landfill gas methane concentration; Landfill gas flow rate to flare; and Destruction/Removal efficiency of flare. The methane concentration of the landfill gas is provided continuously by a dedicated continuous emission monitoring system incorporated into the collection system, just downstream of the flare stack. The provision of dedicated, continuous monitoring of methane concentration is a significant improvement in data availability and reliability over the originally proposed system of periodic manual monitoring with a hand held instrument as given under the original project proposal and as recommended by the PERRL Application Manual. During the temporary flare installation, continuous monitoring was provided by a Non-Dispersive Infrared (NDIR) Model 100-IR continuous analyzer, manufactured by California Analytical Instruments Inc. The stated accuracy of the analyzer was given as better than +/- 1% of full scale. For the permanent installation, the D.H.Lyons Page 5 Feb 2005 Project 05-01
