Curva de Rodas and La Pradera Landfill gas management project 1 Registration No. 2183 Monitoring Report – Version 1.01

Section A: General project activity information

A.1 Title of the project activity

Green Gas Colombia S.A. E.S.P (hereafter referred to as “GGC”) implemented a landfill gas extrac-tion system on landfills near Medellin, Columbia. The Curva de Rodas and La Pradera Landfill gas management project (hereafter referred to as “Project”) has been validated by TÜV Rheinland under reference number 9105044356 Rev. 03 of August, 3rd, 2008 according the Project Design Document version 3 (hereafter referred to as “PDD”). The Project was approved by the Colombian Designated National Authority under reference number N° 2000-2 -46665 on April 29th, 2008 and registered by UNFCCC on February 06th, 2009, under reference number 2183.

A.2 Short description of the project activity

The purpose of the project activity is to install a controlled methane capture and flaring system simul-taneously at the Curva de Rodas and the La Pradera landfills in order to reduce the greenhouse gas (GHG) emission. The project activity takes place in the central north-western part of Colombia. The Curva de Rodas landfill has a total area of 73 ha, from where 33 ha have been used as disposal area. Approximately 8.5 million tons of solid waste has been disposed to the landfill during its operation from the year 1984 up to year 2003, when it was closed. The other project site La Pradera sanitary landfill has been operational since the year 2003. The land-fill La Pradera comprises three modules La Carrilera (3.2 ha), La Música (7.1 ha) and Altair (not de-fined yet, approx. 15 – 20 ha). Currently filling is occurring in the module La Música, this module is permitted to accept approximately 3.5 million tons waste according to the environmental license. Once the module La Música is closed, the filling will occur in the module Altaír, which permitted to ac-cept approximately 6.5 million tons waste according to the environmental license. The landfill receives daily approximately 2,100 tones of waste per day. Hence, the expected closure is in year 2027. The waste disposed at both sites La Pradera and Curva de Rodas comes from the metropolitan area of Medellin, specifically from the municipalities Medellín, Bello, Barbosa, Girardota, Itagüí, Sabaneta, Caldas, Copacabana, Envigado and La Estrella, Guarne, El Retiro and Rionegro.

A.3 Monitoring period

This report covers the monitoring period from 07.07.2008 00:00h (local time) to 05.02.2009 24:00h (lo-cal time).

A.4 Methodology applied to the project activity

According to the classification of the CDM Executive Board the project activity is categorised as waste handling and disposal (sectoral scope no. 13). The revised approved consolidated baseline methodology ACM0001 (“consolidated baseline method-ology for landfill gas project activities”) version 07 is in effect as of November 2nd, 2007 and the related tools have been applied accordingly.

Landfill gas quantity Unit Flow meter

Description The Gas Flow Meter (GFM) consists of two main components, the electronic turbine meter Q75-K with the meter case and the measuring element (with turbine wheel and including temperature and pressure sensor) and the visualization equipment Flowcomp M1n. The GFM measures directly the flow rate at measurement conditions and integrates the measured values; therefore, as a result the gas volume which flowed through the meter is registered by an electronic totalising unit. The gas flow drives a turbine wheel whose speed is recorded through non-contact measurement by a sen-sor. Therefore, the meter is characterized by long-term stability and low wear.

Logging Accumulated gas flow is recorded in the electronic totalising unit of the flow meter.

Revision / Calibrating

According to specifications of the manufacturer (including temperature sensor and pressure sensor) a revi-sion of the Flowcomp M1n should be done according to recommendation of the manufacturer after 5 years by authorized trained staff, Furthermore a yearly spintime test will be done according the recommenda-tions. A periodical revision including a visual check of internal measurement parts assures that the flow meter is in good conditions According to manufacturer’s recommendation a revision/calibration should oc-cur after six years if no damages are located within the period of six years.. During the period of calibration a substitution flow meter will be installed to assure the destruction of meth-ane. Both recommendations will be submitted under request.

Flue gas quality Unit Flue gas analyser

Description The flue gas analysing system is a modular construction and designed for stationary, continuous operation. The measuring gas to be analysed, is taken directly from the flare and fed via the internal measuring gas processor to the measuring instrument. The CH4 channel of the gas analyser is a non-dispersive infrared-photometer (NDIR). The O2 channel of gas analyser uses a chemical sensor.

Logging The flue gas analyser provides two analogue signals, CH4 and O2. The values are recorded as analogue

input signals and measured every minute. Data storage is in the internal memory.

Calibrating According to the specification of the flue gas analyser (see E.2.6), after four weeks of operation this meas-urement device has to be calibrated by the operator. The results of calibration are recorded in a separate protocol which is available on site.

Landfill gas quality Unit Stationary landfill gas analyser

Description The landfill gas analysing system is a modular construction and designed for a stationary continuous opera-tion. The measuring gas to be analysed, is taken directly from the landfill gas pipeline and fed via the internal measuring gas processor to the measuring instruments.

Logging The landfill gas analyser provides three analogue signals, CH4, CO2 and O2. The values are recorded as analogue input signals and measured every minute. Data storage is in the internal memory. Long term ar-chiving is done on an external PC.

Calibrating According to the specification of the landfill gas analyser (see Annex E.2.4), after four weeks of operation this measurement device has to be calibrated by the operator. The results of calibration are recorded in a separate protocol which is available on site.

Flue gas temperature Unit Thermocouple

Description The thermocouple is used to measure the combustion temperature in the flare. If the temperature is less than 500°C or no temperature records exist, the fla re efficiency shall be assumed as zero.

Logging The effect responsible for the thermocouples is the Seebeck effect. It produces a contact voltage at the junction of two different metals, which depends on the temperature at this point. The thermocouple meas-ures the temperature difference between the measuring junction and the reference junction. The tempera-ture of the reference junction must be known and constant.

Calibrating Referring to Methodological “Tool to determine project emissions from flaring gases containing methane” the temperature sensor of the thermocouple will be calibrated each year in the lab of the manufacturer. A backup thermocouple will be installed to ensure the destruction of methane.


Power consumption Unit Power meter

Description For metering power consumption of all project related consumers a multi function power meter DIRIS AM measures the imported electrical energy from the grid. The power meter is a DIN rail mounted multi function meter for measuring electrical values in phases 1, 2 & 3, low and high voltage networks.

Logging As the power consumption is continuously measured and automatically recorded in the power meter, the monthly power consumption is recorded in each visit report. Based on the first reading of each month the power consumption of each month is calculated. The power consumption of the monitoring period is calcu-lated based on first and final reading of the period.

Calibrating According to the specification of the power meter, this measurement device will be treated according to the requirements of the manufacturer.

Backup Equipment Unit Portable gas monitor

Description The portable gas analysing system is a gas monitor designed for portable operation on landfill sites, espe-cially at manifold stations and gas collection pipes. The gas analysing system measures methane (CH4) and carbon dioxide (CO2) by non-dispersive infrared-photometers (NDIR) and records the absorption of the infrared rays caused by the measuring gas. Oxygen (O2) is measured by a chemical sensor (galvanic cell). This analyser will be used for daily operation work on site and for cross-checking landfill gas quality. In cases of emergency or troubleshooting (according to C.5) or malfunction of the stationary gas analyser this portable gas analysing system can substitute the stationary gas analyser.

Logging For daily operation work no data logging is required. In case of malfunction of the stationary gas analyser the readings of CH4, CO2 and O2 can be logged in the internal memory. Long term archiving is done on an external PC (personal computer).

Calibrating According to the specification of the landfill gas analyser, this measurement device has to be checked/calibrated periodically according to recommendation of manufacturer.

Unit Electromechanical hour counter (run time meter)

Description For metering the operation time of the flare an ultra violet (UV) sensor detects the flame inside the combus-tion chamber. The UV sensor consists essentially of a UV-sensitive tube and electronic components. Only when UV radiation is present, generated by a flame or an ignition spark, the tube will switch. When tube has switched the main gas valve will be opened for gas supply to the flare by the automatic burner control unit and landfill gas combustion starts. Simultaneous to the starting process this control unit activates the electromechanical hour counter for metering the operation time of the flaring process.

Logging Accumulated operation time of the flare is logged only at the electromechanical hour counter and has to be recorded manually in each visit report.

Calibrating According to specification of the manufacturer the run time meter can neither be modified nor be calibrated for the counting range of 99999.99 hours. It works or it is defect and a reset is not possible.

In case of any future modifications the training for the modified items will be repeated according to such specifications.

C.4 Internal audits and control measures

All collected data are controlled on a monthly basis according to scheduled controlling meetings within GGG based on internal quality management activities. The general status of the plant including all technical details is controlled monthly based on the monthly operation journals provided by GGC. Based on monthly reporting, periodic maintenance steps will be scheduled quarterly by GGC and ar-ranged with GGG and / or any external service partner. On a semi-annual base the site will be visited by GGG to advise technical control and any service ac-tivities that need to be done by specially trained service staff. On an annual base the technical control and service activities are verified by GGG and updated ac-cording to modifications.


C.5 Troubleshooting procedures

In case of any failures or malfunction at the flare-booster-station the local party in charge for service and operation on site (GGC) would get a text message on mobile phone sent by the remote control system. GGC would visit the site time for inspection and identification of the failure as soon as appro-priate. Failure and potential cause shall be recorded in the operation journal and the visit report. In case of unclear situation GGC contacts GGG for consultation and technical service support. In case of any emerging specific technical problem external service suppliers might be involved for support. In case of any failures or malfunction at any measurement device the following trouble shooting pro-cedures shall be carried out to meet the requirements of the monitoring methodology:

Power supply failure

In case of any power outages the complete landfill gas extraction system including booster and flare is out of operation as there is no emergency power supply installed. Therefore, all measurement devices would be out of operation. Recorded data are secured on a separate memory card in the substation of the flare-booster station as well as on hard drive of the local computer on site. GGC will analyse the situation as soon a possible and solve the failure if the problem is located internally. Any locally se-cured data are sent to GGG, respectively to the Central data Server.

Failure of gas flow meter

In the unlikely event of any malfunction of the gas flow meter, this measurement device and/or any other related equipment will be repaired or exchanged as soon as possible. In the meantime, GGG and GGC will choose a feasible and technically reliable method to determine the gas flow rate.

Failure of energy meter

In the unlikely event of any malfunction of the energy meter, this measurement device and/or any other related equipment would be repaired or exchanged by spare parts as soon as possible. In case of any failure of the energy meter the energy consumption of the project is recorded by the energy me-ter of the public energy provider based on monthly invoicing and can be provided on request.

Failure of landfill gas analyser

In the unlikely event of any malfunction of the landfill gas analyser this measurement device and/or any other related equipment would be repaired or exchanged by spare parts as soon as possible. In case of any failure of the oxygen analyser the plant will shut down because of safety reasons. In case of any failure of the carbon dioxide analyser no additional trouble shooting processes are necessary as this parameter is not required for calculating emission reductions. In case of any failure of methane analyser the carbon dioxide and oxygen measurements can be used for determining the methane fraction in landfill gas. In addition to this indication, regular measurements with a handheld landfill gas analyser will be carried out and recorded manually (please see E.2.5), Failure of data-logger

In the unlikely event of any malfunction of the substation the data-logger and/or any other related equipment would be repaired or exchanged by spare parts as soon as possible. In case of any failure of the data-logger the following measurement devices work independently:

- gas flow meter - energy meter - electromechanical hour counter

Besides these independent measurements landfill gas quality including methane concentration has to be recorded manually according to the trouble shooting procedure for failure of landfill gas analyser.


In case of any failure or malfunction of logging the data from gas analyser a linear trend-interpolation is made. This means that a linear trend between the last logged data before the failure occurred and first logged data after repair of logging system is created. The difference between last logged value and the first logged value is divided by the number of missing data. This value is added to the start value for calculating the first missing value. For calculating the second value the difference is added to the first calculated one. This is done for all missing values. Any manually recorded data collected dur-ing site visit are taken into consideration for the linear trend-interpolation as logged data to be put into data-logging protocol.

Section D: Monitored and calculated data

D.1 Calculation of greenhouse gas emission reductio ns

The calculation of VERs is carried out per minute based on raw data as logged. All parameters which are mentioned in Section B.1 are stored by the archiving system and used in the calculation. Referring to the ACM0001 (version 7), the greenhouse gas emission reductions of this project are cal-culated by the following equation:

ERy � ��LFG�lared,y�wCH4�DCH4 – �PE�lared,y GWPCH4

D.3 Description and consideration of measurement un certainties and error propa-gation

Due to the fact that the tolerances of the measurement devices for volume flow, methane concentra-tion and power consumption are very low (< 3.0%) measurement uncertainties are not considered. Based on regular maintenance according to specification of the most relevant measurement devices for volume flow and methane concentration any variances are reduced to a minimum and a calculation of error propagation based on a variance analysis of the different measurement devices is negligible.

D.5 GHG emission reductions

The amount of fugitive and remaining landfill gas emissions (project emissions) leaving the project boundary is derived by subtracting the estimated amount of captured methane from the estimated baseline emissions. Carbon dioxide (CO2) is generated as direct source of emissions from the project by combustion of methane. According to the PDD and in consideration of the baseline emissions, leakage and sum of the emis-sion reductions the total project emissions for the relevant monitoring period are 20,469.7 tons of CO2e. All raw data, weekly and monthly reports that form the basis of total emission reductions are attached as open Excel-sheets in Sector E.5. Based on the monitoring sheets the total emission reductions produced during the monitoring period are as follows (table D.5): Table D.5 Summary of emission reductions (in total) Total emission reductions according to monitoring sheets 20,688.4 tons CO 2e Total emissions from flaring of the residual gas stream 77.6 tons CO2e Total emissions by power consumption 141.1 tons CO 2e Total emission reductions 20,469.7 tons CO 2e
