1) The DOE states in the verification report (p. 9) that the PDD specifies that the CO2 concentration is obtained with a gas analyzer using the “Orsat” method of volumetric analysis with an accuracy with a ± ½ percent uncertainty range; however, the accuracy of the Landtec portable gas analyser used, which is  3% for CO2 contents above 15% in line with the specifications for the equipment by the supplier, represents in DOE’s opinion good monitoring practice even if less than what was specified in the monitoring plan. The secretariat has noted that according to Sec. D.2.1.3 of the PDD, the parameter % CH4 in biogas (ID#21) is to be measured periodically with confidence level of at least 95%.  The DOE is requested to clarify which requirements in the PDD and revised monitoring plan applies to the verification of this parameter, considering that sections D.2.1.3 and Section D4 of the PDD and the revised monitoring plan refer to different ways of measuring the methane content of biogas. Please refer to VVM version 01.2 paragraph 205 (c).
