Scope: The verification report does not provide an assessment on whether the calibration of measuring equipments was conducted at a frequency specified in applied monitoring methodology or EB guidance if applicable, and/or the monitoring plan (VVS v2, para 243)
Issue: The registered monitoring plan (page 21) specifies that there was a delay in calibration of the thermal gas mass flow meter used to measure the total amount of landfill gas flared (LFGflared,y), thus the error measured from the delayed calibration result (8.11%) was applied for the period 20/11/2009 – 15/02/2010. The validation report (page 19) states that in order to comply with the VVS paragraph 242, it validated the test certificate provided from the original equipment manufacturer. However, the spreadsheet shows that a manufacturer’s adjustment formula was used to correct the values for the whole monitoring period. Therefore, the DOE is requested to provide a validation opinion on a) how it considers that the manufacturer’s adjustment formula is conservative as the validation report does not provide any information on it and b) clarify the discrepancy in the duration when the correction was applied, as the correction has been applied to the whole monitoring period while the validation report pages 21 and 105 mention that the correction of values has been done for the period 20/11/2009 – 15/02/2010.
