Contaminant Concentrations in Traditional Fuels: Tables for Comparison

This document includes tables that present summary statistics for contaminant concentrations in common traditional fuels. Members of the regulated community may find the data presented useful when comparing contaminants in their non-hazardous secondary materials (NHSMs) to contaminants in the appropriate traditional fuels. EPA has organized and presented this data as a service to assist non-hazardous secondary materials processors and combustors in making contaminant comparisons. The Agency will periodically update these tables as additional data become available.
