What must facilities document when using estimates for diversion calculations?

When facilities use estimates for diversion calculations, it is essential for them to document the methodology and source references for those estimates. This requirement ensures transparency and credibility in the waste diversion process. By clearly outlining how the estimates were derived and citing the sources of data or methods used, facilities provide a traceable path that allows for verification and understanding of the calculations. This information is critical for stakeholders, such as regulators or auditors, who may review the diversion efforts to ensure compliance with waste management regulations and goals.

Documentation of the methodology also aids in replicability; if other facilities or analysts wish to conduct similar calculations, they can follow the same approach. Furthermore, it strengthens the integrity of the data reported, as it shows that the estimates are not arbitrary but based on systematic methods. Having well-documented estimates can further support a facility's assessments of their environmental performance and progress toward waste diversion objectives.
