Midshore Regional Solid Waste Facility (MRSWF) Landfill Gas Combustion Project

Audit Analysis

A long-running (since 2009) landfill gas destruction project with verified additionality but a troubling history of monitoring quality failures, including calibration lapses, data gaps of up to 158 days, and calculation errors (GWP, eGRID factors). The project delivered only ~37% of its pro-rata ex-ante expectation for the 2022 monitoring period, partly attributable to data logger failures. The absence of a buffer pool, a project-specific modeled baseline, and weak safeguards documentation limit confidence in the credit's robustness.

Project Description

Red Flags

• ⚠158 days of missing flow and methane data in 2022 due to data logger failures, directly reducing verified reductions to 37% of pro-rata expectation
• ⚠Over 80 material findings and corrective actions across the project's history, including repeated calibration failures, GWP errors (21 vs 25), and incorrect eGRID factors
• ⚠FPIC not conducted, no grievance mechanism confirmed by the VVB, and benefit sharing not described
• ⚠Methane sampling frequency (1/week) below the CDM Tool 08 requirement (2/week), requiring a 10% conservative discount
