Monitoring: 1.1 Title and reference of the VCS methodology (which includes the monitoring requirements) applied to the project activity and explanation of methodology choices: UNFCCC CDM AMS III.Y version 01: Methane avoidance through separation of solids from wastewater or manure treatment systems, clause 29 Monitoring. The methodology applies to the project described herein as explained in section 2.2 of the present document. 1.2 Monitoring, including estimation, modelling, measurement or calculation approaches: The project s energy consumption data and dairy manure data are collected on site. BOS Farms is responsible for the data collection and input. The data is kept at the head office and are compiled on Excel spreadsheet. Specific analyses of the solid and liquid parts of the manure separation are done by an independent biochemical laboratory. As a requirement from the CDM methodology III.Y, the dry matter content of the separated solid must be higher than 20%. Based on Chastain (2008) 1 study, the US Farm mechanical separators with two screens can remove close to 59.7% of the total dry matter from the manure stream. 1.3 Data and parameters monitored / Selecting relevant GHG sources, sinks and reservoirs for monitoring or estimating GHG emissions and removals: Electricity consumption kwh Electricity consumption for the processing pit pump 2007-1 147 378 2009-3 081 025 QA/QC procedures to be Section 5.10 of ISO 14064-2 2 Diesel consumption 1 Chastain, J.P, 2008.

Separated solids (kg) Specific data on the separated solid part of the manure. The percentage used is 8.4% for the least efficient system and 65.7% for the more efficient one. Evaluation and testing done by Les Consultants Valéro Inc. presented in the report entitled: Efficacité relative des filtres métalliques pour la filtration des excréments de bovines (Californie); and Ph.D. John P. Chastain: Field Evaluation of a two-stage liquid-solid Separation System at a California Dairy. All solids separated expressed in tons: 2007-4538.60 2009-4629.55 The method applied implies a multiplication of the percentage of solids separated by the number of cows and by the volatile solids produced by a cow.

Dry matter content (%) of the separated solid. Specific data on the separated solid part of the manure. Evaluation and testing done by an independent biochemical laboratory. Dry matter content: 2007 Stage #1: 76.09% Stage #2: 79.63% 2009 Stage #1: 22% Stage #2: 20.3% The data is compiled based on batch testing. The results can be extrapolated to similar situations. QA/QC procedures to be Section 5.10 of ISO 14064-2 8 1.4 Description of the monitoring plan General Information The data collection for the GHG emissions reduction project was completed during a site survey. Collected data originates from two sources: the farm's owner and US Farm. The project is managed by the farm's owner in collaboration with US Farm. The data verification was completed directly between the GHG quantification technical expert and the farms' owner. Original documents were consulted and copies were obtained. Client data is saved on a per farm basis. An information checklist summarizes the data available for each farm. US Farm Maintenance Program The Maintenance program is either implemented by US Farm or the farm s owner and consists in the complete stop of the separation process to allow US Farm technical team to clean filters and to proceed with the equipment mechanical maintenance (motors, etc.) US Farm also provides separator cleaning service using water jets. US Farm Maintenance Program is performed methodically and periodicaly, every three months. In the case of this project, the farm s owner is responsible for the maintenance program. Also, in this project, based on collected data, the separators are considered to be operational 360 days per year. Collected data and collection frequency 8 International Standards ISO 14064-2:2006(F), Section 5.10, P.13.
The characteristics of each animal included in the manure handling system will have to be kept up to date year after year. For instance, each year, the number of animals, the animal type, the farm system equipment and the average weight will be taken into consideration. Any change in the process frequency or any change made in the used technology must be reported. Data storage The information will be stored at the dairy farm as well as in a computer located at US Farm s offices. This data is available in electronic format. Backups are done on removable hard disk and provide access to the data from the last 10 years. Older data is in paper form.
