Improving Methane Emission Estimates from Nonsewered Wastewater during Storage in Septic and Holding Tanks
when normalized by the surface area of the containment. Methane correction factors (MCFs) calculated in this study were different from those recommended by the IPCC. These results reveal important limitations in the IPCC methodology for scaling point-source measurements using current Tier 1 defaults, including the difficulty of reliably estimating organic loading values and population equivalents, and the inadequacy of IPCC MCF values to represent highly variable and context-specific conditions in containments.
