Spartanburg County Landfill Gas Combustion Project

Audit Analysis

The Spartanburg County Landfill Gas Combustion Project has a fundamentally sound design with VVB-confirmed additionality, inherent permanence (methane destruction), and a reasonable zero-leakage position. However, the project is burdened by an extensive catalogue of data-quality findings, calibration lapses, and calculation errors spanning multiple monitoring periods, and the low extraction confidence in the underlying documents limits assurance. The project-specific baseline and ambiguous ERR reporting basis introduce moderate over-crediting risk.

Project Description

Red Flags

• ⚠Extensive material findings (40+ items) spanning calibration lapses, calculation errors, missing data, and documentation gaps across multiple monitoring periods, indicating systemic MRV weaknesses
• ⚠Minimum extraction confidence rated 'low', meaning at least one key document was poorly readable, reducing assurance in the extracted data
• ⚠Grid emission factor contradiction between 0.2677 (2025 monitoring report) and 675.4 (2022 monitoring report) suggests unit confusion or data-entry errors in the MRV chain
• ⚠FPIC not conducted and benefit-sharing described as absent in the most recent monitoring report, despite a grievance mechanism being confirmed in the 2020 verification report
• ⚠Flow meter SN 42055 was out of calibration for August–December 2021 with only a 1% discount factor applied, and the SCADA system stopped recording gas analyzer data for over a month in 2019
