CDM project activity/programme of activities issuance request review form (CDM-ISSR-FORM) (Version 03.0)

Project title of the project activity or programme of activities (PoA) for which issuance is requested	AWMS Methane Recovery Project BR07-S-31, Mato Grosso do Sul, Parana, Rio Grande do Sul, and Santa Catarina, Brazil (1531)
DOE that requested for issuance and date of request	DNV (29 Mar 12)
Please indicate, in accordance with paragraphs 65 of the CDM modalities and procedures, for which reason(s) you request review
Incompetence
Please indicate reasons for the request for review
1) The monitoring plan of the revised PDD (page 28) states: a) ¨Accuracy of the flow meters utilized exceeds 99 percent across the entire measured rate curve with an uncertainty range of less than + 1 percent¨; b) Methane concentration is determined using a Bacharach Model Fyrite (or equivalent) gas analyzer. The process is described in the Monitoring Plan. The measuring equipment is calibrated in accordance with the manufacturer specifications. The equipment is accurate to within 0.5%." However, the Verification Report (pages 6 and 7) states: a) The PDD does not specify the accuracy. The type of flow meter applied represent good monitoring practice. b) The maximum error rate for methane with volume between 15 and 100% as per the operating manual of the LandTec Biogas Check portable gas analyzer is 3% and represent a good monitoring practice. The DOE is requested to further clarify how it assessed the consistency of the accuracy equipment (i.e. Roots flow meter and Landtec gas analyzer) used to monitor the volume of biogas and the methane content of the biogas with the accuracy and monitoring method specified in the revised monitoring plan. Please refer to VVM version 01.2 paragraph 205 (c).
